1. INTRODUCTION:

Pedal power washing machine means applying the pedal rotate the drum attached with the

shaft by means of chain drive and create the resistance (Turbulence) between inside drum

water, cloth, powder to wash the cloth.

“To support the basic family economy, through the design and distribution of bicycle

machines, providing an efficient alternative for the rural development of India.”

Women in GUJARAT (also in India) wash clothes manually, but the detergents are

chemically harmful to their hands, and the motion of scrubbing is straining to the muscles.

Our goal is to design an inexpensive and durable pedal-powered washing machine for use in

rural areas to gently wash clothes. Due to cost constraints, the washing machine is to be

shared among several families or can be used by a local entrepreneur to run a laundering

service. The washing machine must be easy to build and maintain locally with local

materials, easy to operate (minimal required steps), and easy to power by women or

children. It must also be more comfortable to use than manual methods and culturally

acceptable in GUJARAT.

2. HISTORY:

One of consequences of globalization is that there is great competition in

the market and it is increasingly specialized. Every day, there are more

types of washing machines. The available models get more and more

effective, noiseless, economical, light and their design adjusts to the place

where you want to place them. That is why you should exactly know the

type of machine you are looking for, its particular features and the key

questions you should ask the salesperson.

Fig.2 19th-century metropolitan washing machine Fig.3 a vintage German model

Page 11: Project Report "Peddling Washing Machine"

There are many kinds of washing machines. Some of them are for industrial use and others

for consumer use; some have top-loading and others front-loading design; some of them

include spin dryer and others do not. Nowadays, many washing machines offer digital

technologies that help you control details such as time, speed and vibrations during the

drying process. Modern machines' goal is to finish a great load of work in a short time, with

the less possible users' help.

As a consequence of the great variety of machines in the market, you should take many

fundamental aspects into account, such as what you will use it for -for industrial or consumer

use-, how often you will use it -daily or weekly-, and the room you have for it -large or tight.

Fig.4 Industrial w/s m/c

The origin of washing was a consequence of different changes in the clothes materials and

the new esthetics of the fashion world. The different materials that appeared required

different ways of washing them. All fabrics could not be washed the same way -each type

required specific cares.

1. At first, clothes were washed in vats with hot water and soap, and the fine fabrics were kept

soft.

2. In 1780, technology began to appear with Robinson Lancashire, who invented the washing

machine, which also dripped clothes.

3. In 1855 a machine to wash and dry clothes was invented in Crimea's hospitals.

4. In 1880 the first washing machines were built. They heated water with gas and coal.

5. In 1888 the electro-technical engineer Incola Tesla invented a compact electric engine which

joined electronics with washing.

Page 12: Project Report "Peddling Washing Machine"

6. In 1901 the American engineer Alva Fisher invented the first washing machine, adding to

the already existing machines an electric engine which impelled a cylinder. An automatic

mechanism inverted the spinning sense from time to time so that the clothes did not

compress, which frequently used to happen. The next step was to add some rollers to drip

clothes. This is the date when the first washing machine was born.

7. After the Second World War, in 1945, washing machines started being highly sold in the

Western countries. The washing machines were sold in series, and manufacturing was

distributed. They were cheaper.

3

8. In 1960, important industrial companies began to manufacture huge amounts of washing

machines, and others turn them into their main source of prestige and earnings -as Kelvinator

and Zanussi.

9. In the 70's, the washing machine was definitely a well known product in Europe and

America.

Fig.5 washing machine

The esthetic and functional evolution of the washing machine has developed, especially during the

last years, with the use of microelectronics. Some of the elements that have been added and have

enhanced the washing machine are:

Page 13: Project Report "Peddling Washing Machine"

Nowadays, drain pipes let dirty water go out and let clean water come in without the need of

doing it with the hands like some years ago. Besides, the city plumbing system is involved

here too.

Nowadays, the door has a mechanism which is connected to the microprocessor to avoid

dangers. The machine does not start until the door is closed. We can also watch the interior

process to check if it is taking place normally.

Their materials are lighter today. Many years ago, wood materials were used, but now

washing machines are built with stronger materials such as aluminum or enameled materials.

Today's trend is to join material's quality with lightness and design.

3. WASHING MACHINE:

Although the breakthrough technology of the different brands turns each washing machine

into a unique device, we can define the minimum and basic function of a washing machine.

The washing machine has a central loading cylinder with holes and a spinning system on its

own axis. Once it is filled with water, the process ends and throws the machine contents out.

Its function is based on a spinning movement over a container, generally of cylindrical shape.

Inside of it, water, detergent and dirty clothes are mixed. This movement mixes the detergent

with dirtiness and the relative movement between water and clothes, which develops the

cleaning process. Automatic washing machines have a program system that allows the

machine to perform different cleaning processes. According to the one you chose, spinning

speeds vary as well as the time and the chosen temperature.

The basic components of the machine are:

An electric engine which transmits movement to the cylinder so that it spins in the right way.

A microprocessor that controls the function of the different cleaning choices as well as the

programs. This device orders the priorities.

A cylinder or tube which mixes the clothes, water and detergent and which acts as a

container for the elements.

Page 14: Project Report "Peddling Washing Machine"

A small vat which protects and supports the tube or cylinder, allows water and temperature

changes, and supports all the elements while the process changes.

3.1 TYPES OF WASHING MACHINE:

Nowadays, there are two types of washing machines. This classification depends on the place where

clothes are introduced: top-loading or front-loading washing machines. Top-loading machines are

frequently found in the United States, Canada, Australia and many African and Asiatic countries.

They are tighter, which means that they occupy less space. They are perfect to use when you have

space problems. The front-loading machines are found in Europe and they are more popular ones.

Both of them have the same capacity to load clothes and the same functions.

There are also different types of washing machines according to use and frequency of use. There are

industrial washing machines -with more capacity- and machines for home use. There are some

washing machines with complex services that include the temperature of the drying water. They are

ideal for people who live alone. There are also washing machines which include minimum processes

and they are cheaper. It all depends on the needs and user's choices.

Page 16: Project Report "Peddling Washing Machine"

Finally, we can find automatic and semiautomatic washing machines. The difference is the number

of elements that you have to bear in mind to wash clothes. This classification has to do with the

user's dedication when washing.

7

3.1.1 TOP-LOADING VS. FRONT-LOADING WASHING MACHINES

Washing machines come in two types: top-loading and front-loading. Top-loading washers have a

lid on the top of the machine, and most use an internal agitator that spins on a vertical axis to churn

the water and clean the laundry. Top loaders are easier to load and unload than front-loading

machines (since you don't have to stoop over to unload them), and they cost around $400 less on

average than front loaders. However, top-loading washing machines are less efficient than front

loaders because they use more water and energy.

Since energy efficiency is such an important shopping consideration, a number of manufacturers

now make energy-efficient top-loading washing machines. According to EnergyStar.gov, Energy

Star-rated washing machines use about 30 percent less energy and 50 percent less water than non-

qualified machines. Replacing a 10-year-old washer with a new Energy Star machine, they say, can

save the average person about $135 per year on utility bills.

The construction of energy-efficient top-loading washers can vary. Some, like traditional top

loaders, use a central agitator, but many rely on different mechanisms such as impellers, which

reside on the bottom of the washing tub and move laundry throughout the wash in a circular motion.

Page 17: Project Report "Peddling Washing Machine"

These eco-friendly appliances are more expensive than traditional top-loading washers, with prices

that rival those of front loaders. They may also require high-efficiency (HE) detergent, which

produces fewer suds. High-sudsing regular detergent may not be rinsed out completely in high-

efficiency washing machines due to their low water use. Another problem: These new energy-

efficient top loaders, with their high spin speeds, can tangle and wrinkle laundry.

Front-loading washing machines are the most popular option. In addition to using far less water and

energy, they demonstrate the best overall washing performance in comparison tests. These washers,

which look like those found in professional laundries, have a door on the front; laundry is put into a

stainless-steel drum that spins on a horizontal axis. These washers typically feature higher spin

speeds than top loaders, wringing out more water so that laundry requires less time in the dryer.

They also tend to offer more bells and whistles, such as additional wash cycles and high-temperature

cycles. Some front loaders also include special deep-cleaning steam cycles.

8

3.1.2 TOP-LOADING WASHERS

TRADITIONAL TOP LOADERS ARE CHEAPER

Old-style top loaders aren't as "sexy" as more stylish front-loading washing machines, but they still

have some advantages. First, they are generally cheaper than front loaders, often hundreds of dollars

less. Although less efficient, top-loading washing machines can be easier to load and unload than

front-loading machines, since you don't have to stoop down. They also make it easier to add items in

mid-cycle (you can't do this at all with a front loader). Another major advantage top loaders have

over front-loading washers: They aren't prone to mold and mildew buildup in the door gasket.

Many manufacturers of top-loading washing machines are aiming to make their washers more

energy efficient. In terms of cleaning performance, energy-efficient top loaders fall somewhere

between conventional washers and front-loading washing machines. Pricewise, however, the newest

top-load machines can cost as much as more efficient and generally better-cleaning front-load

machines. Even so, many owners prefer top loaders for their easy loading and unloading and for the

ability to add items to the cycle after it's started.

Unlike traditional top loaders, which use an agitator to circulate laundry in the water, the Maytag

Bravos has an impeller at the bottom of the washtub that moves laundry through the water. As

Page 18: Project Report "Peddling Washing Machine"

Maytag describes it, "The load is moved from the outside toward the middle with items coming up in

the center and down on the outside edges." It requires high-efficiency (HE) detergent, which

produces fewer suds than regular detergent.

The Maytag Bravos MVWB750WQ excels in independent testing. In one test of top-loading

washers, it was among the top-ranked products, with good to excellent scores in every category. This

machine gets high marks from owners as well. Over 50 reviewers at HomeDepot.com, roughly 30 at

BestBuy.com and another 25 or so at Sears.com give the Maytag Bravos MVWB750WQ average

ratings of approximately 4 stars out of 5. Users rave about the washer's high capacity, with one

reviewer saying that this machine can do in one load what others do in three. They are also

enthusiastic about its quiet operation and the fast spin speeds that wring clothes out nearly dry.

9

3.1.3 FRONT-LOADING WASHERS

FRONT-LOADING WASHING MACHINES GET THE BEST REVIEWS

Front loaders are both the most efficient washing machines and the best overall performers,

according to professional tests. Their horizontal tubs tumble clothes into and out of the water,

making it possible to wash a full load without filling the tub completely. On average, front loaders

tend to be gentler on clothes than top-loading machines, as well as more efficient. The bad news is

that front loaders cost more than traditional top loaders (though not much more than high-efficiency

top loaders), and they still get complaints for reliability. On average, however, the differences in

reliability between top loaders and front loaders are not significant, according to owner surveys at

ConsumerReports.org.

Front loaders use about half as much water and two-thirds as much energy as conventional top-

loading washers, according to the National Geographic Green Guide. In addition, their fast spin

speeds remove more water from clothing, thereby reducing drying time and resulting in further

energy savings. However, this high-speed spinning can also cause clothes to become tangled and

wrinkled. Because these machines use so little water, they require special low-sudsing high-

efficiency (HE) detergents that can cost more than regular laundry detergent.

Page 19: Project Report "Peddling Washing Machine"

Another caveat is that because of their design, front-loading washers require more daily attention.

For example, we've read many reports that front loaders can develop mold and mildew problems

caused by moisture and dirt being trapped in the door seal after a cycle. Some users say that wiping

away water after a cycle and leaving the washer door open when the machine is not in use will

prevent the problem, but others have tried this approach without success. Afresh Washer Cleaner

Tablets, developed by Whirlpool, are supposed to combat mildew and odors in high-efficiency

washers. These tablets get a 4-star rating in over 50 reviews at Amazon.com. Some owners report

great success and improved freshness, but others say the tablets don't make a dent on odor.

Whirlpool and Maytag, in their high-end front-loading washers, are now including a small fan that

can blow air inside the empty washing machine. Company representatives told us that using the

internal fan is supposed to dry out any water that might remain in the washer and gasket after a

cycle, but since this feature is so new, we haven't seen many reports from owners on how well

it works.

10

3.2 FURTHER COMPARISONS

Top-loading washers do not suffer from continued maintenance problems and needs no regular

freshening. During the spin cycle, a top-loading tub is free to move about inside the cabinet of the

machine, using only a lip around the top of the inner basket and outer tub to keep the spinning water

and clothing from spraying out over the edge.

There are many variations of these two general themes. Top-loading machines in Asia use impellers

instead of agitators. Impellers are similar to agitators except that they do not have the center post

extending up in the middle of the wash tub basket. There is also a variant of the horizontal axis

design that is loaded from the top, through a small door in the circumference of the drum. These

machines usually have a shorter cylinder and are therefore smaller, but offer the efficiency of a

front-loader while eliminating the problems of the flexible bellows. This kind of washing machine is

sold and popular in Europe, especially in small households, because it offers the same drum system

as front-loaders, just with a smaller footprint.

WATER LEAKAGE

Top loading machines are less prone to leakage. Front loading machines require a seal on the front

door, and similarly the front door must be latched during operation to prevent opening, lest large

Page 20: Project Report "Peddling Washing Machine"

amounts of water spill out. This seal may leak or require replacement. Many current front-loaders,

though, can be stopped and added to or removed from, by way of keeping the water level in the

horizontal tub below the door level.

ENERGY USAGE

Front loaders use less energy, water and detergent and clean more effectively than the best top

loaders.

WATER USAGE

Front loaders generally use less water than top-loading residential clothes washers. Estimates are

front loaders use anywhere from about one third to one half (Consumer Energy Center) as much as

top loaders.

11

COMPACTNESS

Front loading machines may be installed underneath counters. A front loading washing machine, in a

fully-fitted kitchen, may even be disguised as an ordinary base cabinet/unit. They may also be

convenient in homes with limited floor area, since the dryer may be installed directly above the

washer.

SPIN-DRY EFFECTIVENESS

Front loaders also offer much higher spin drying speeds of up to 2000 RPM. This makes it possible

to dry clothes very quickly by hanging them on washing lines or airing racks or can substantially

reduce the length of time required in a tumble dryer.

NOISE

Front loaders tend to operate more quietly than top loaders, since there is less of a tendency to

imbalance.

ACCESSIBILITY AND ERGONOMICS

Front loaders are more convenient for little people and those with paraplegia, as the controls are

front-mounted and the horizontal drum eliminates the need for standing and/or climbing.

Page 21: Project Report "Peddling Washing Machine"

For people who are sufficiently tall and can stand, top-loaders may be easier to load and unload,

since reaching into the tub does not require stooping. However, this issue can be mitigated due to the

offering of risers (usually with storage drawers underneath) to raise the front loader door opening

closer to the user's level.

MAINTENANCE WASH

Most, if not all consumer washing machines, now use a plastic outer shell instead of stainless steel

to contain the water. Washing machine manufacturers are now advising users, due to the plastic's

adhesion properties with laundry detergent and mold, to perform a regular maintenance wash which

cleans the inside of the washing machine. A maintenance wash is performed without any laundry on

the hottest wash programme, using either one of the following: white vinegar, a detergent with

bleaching properties or you could use a proprietary washing machine cleaner. The purpose of a

maintenance wash is to remove any mold, bacteria, old detergent residue and gunge.

12

3.3 WORKING PRINCIPALE OF WASHING MACHINE:

A washing machine has become a vital household item that most people simply cannot do without

these days. For one, it is designed to make washing clothes a lot easier. If you have already tried

washing your clothes by hand, then you’ll certainly understand what it means not to have this

appliance with you.

A washing machine is a pretty straightforward piece of contraption which can be

run by practically anybody. It is designed to remove dirt and stains from your

clothes and make them suitable for wearing again. The machine moves the

clothes about in soap suds and spins them around to separate water later on.

One thing that you should understand about how washing machines work is that

these contraptions are actually made of two drums instead of one. The inner

drum works to let water in and out to spin your clothes and clean them and has

a lot of small holes on it for that purpose. The bigger drum, that you really don’t

see works to hold water while the inner one works on spinning your clothes

around.

Page 22: Project Report "Peddling Washing Machine"

The machine also has an electrically-powered pump which works to remove water from the drum

after you’re done with the laundry. All these parts are controlled by a central programmer.

The programmer is an essential part that will explain how washing machines work. You can

probably think of it as the brain of the whole machine because it regulates all sorts of tasks. It makes

the machine goes through the whole process of washing clothes – wash, rinse, and spin. The

programmer also dictates the wash cycle to use according to your specifications. Clothes have

different wash requirements so it’s important for the programmer to be given specific instructions to

enact.

Once the detergent has done its job in removing dirt from your clothes, the drum opens to drain the

wastewater and then replace it with a cleaner one. This will then be used to rinse your clothes. After

rinsing, the drum will rotate at high speed to spin your clothes around, separate water from them and

dry your laundry.

13

3.3.1 WORKING STAGES:

Generally, the washing machines are 60 cm. broad and deep (23 inches), and 85 cm. (33 inches) - 1

meter (39 inches) tall. In some special occasions, we can find 60 cm. deep washing machines. The

main feature of these types of machines is that they have a helix deep inside with a rotation system

which twists the clothes and helps them wash filth with specific detergents. The vast majority has a

timing control and a draining system.

The cloth capacity is measured by kilograms. A standard machine has a capacity to store between 5

and 7 kg. This capacity changes according to particular needs and the clothes' fabric. It is important

to bear in mind that the kilogram capacity is an industrial parameter reference between the

manufacturers, not a limit for the user.

Page 23: Project Report "Peddling Washing Machine"

The washing process is divided in two stages. You need to follow them in order and carefully to get

a good cleaning. The steps to follow are:

1. In the first place, clothes selection. You need to select and distinguish white and colored clothes.

The colored clothes should not dye the others. You should separate clothes according

14

2. To the material they are made of, size or use. You need to read the brand's instructions on the

clothes (some of them can be washed in a washing machine, others cannot) and the washing

machine's manual as well.

3. The next step is to use the detergent and the smoothing products -if they are necessary. You need

to buy washing machine detergent and, if it is possible, a low-foam one. Following the

instructions, the idea is to use the same amount of detergent as the amount of clothes included in

the machine. Detergent overuse does not wash the clothes better. As regards smoothing products,

they are specially used with cotton or fine clothes.

4. Next, the washing machine process begins. It includes three steps: washing, clearing and

spinning. In some occasions, it also includes drying. The first step is the input of water and the

wash. Water fills the machine up to the necessary level for the process depending on the loading

amount. If there is a timer, it will be filled according to the accurate temperature. While this

happens, the machine starts washing, setting its engine. Detergent is mixed with water and

clothes are twisted by a pressing system.

Page 24: Project Report "Peddling Washing Machine"

5. After some time and after the washing process has been carried out, the clearing process begins.

The already used water is eliminated by means of an internal filtering system. A series of rinsing

steps is carried out; some of them can be programmed. Generally, four or five rinsing steps are

carried out until detergent is fully eliminated. To the end of the process and if you have indicated

so, smoothing products are added. You need to tell the machine how you want to wash your

clothes. That is why you need to select the program, temperature and type of loading.

6. The last step in the process is the spin process, which helps get the clothes even drier. As there

are more revolutions, the clothes will be drier. Some machines have a double spin system and

some allow you to choose a soft spin or even avoid it.

7. Finally, and in fewer cases, the drying process is included. Washing machines which offer this

type of service are very expensive, so this step is usually ignored. However, we should highlight

that some clothes are damaged due to high intensity drying.

15

Page 25: Project Report "Peddling Washing Machine"

We could summarize the process in the next steps:

Open the door.

Pour the detergent in the right place. You should use low-foam detergents and, in case water

is very heavy, you could use a smoothing product.

Classify clothes: Clothes with different types of fabrics or colors should be washed

separately from the others.

Select the program.

Introduce the clothes.

Close the door.

Press the on/off button.

When the washing process ends, press the same button again.

16

3.4 WASHING MACHINE DETERGENTS

Washing Machine Detergents are solutions used for cleaning the laundry items such as the clothes,

towels and bed sheet. Washing machine detergent is used in the washer, a mechanism designed for

cleaning the clothes in a washing machine.

Water is used as the main source for cleaning of clothes and washing machine detergent is used as a

cleaning fluid that helps in the removal of stains and dirt from the clothes. The energy created in the

washing machine induces the washer to wash the clothes and the washing machine detergent cleans

the stains in the process of washing.

There are two types of detergents used for washing purposes, cold water detergent and hot water

detergent.

Page 26: Project Report "Peddling Washing Machine"

These detergents has to be used depending upon the temperature of the water. Washing machine

detergents play an ultimate role in keeping the clothes fresh and dirt free. It is compulsory to wash

the clothes using detergents and this process provides clean clothes.

DIFFERENT TYPES OF WASHING MACHINE DETERGENTS

Washing Machine Detergents are available in the market in different forms. Some of the popular

types of washing machine detergents are washing powder, washing liquid, washing soap and

washing tablets. Washing powder comes in a powdered form and they are easily soluble in water.

The washing powder provides lot of bubbles and fragrance to the washing water.

Washing powder is easily dispensable and protects clothes from germs and dirt. Washing liquid is

something which is watery in nature and it can be used by pouring the liquid into the water, it easily

combines with the water and removes tough stains and grime from the clothes.

Washing tablet comes in the form of small buttons and they are easily soluble in water, these tablets

can be dropped inside the washing tub and on rotation of the tub the tablet dissolves and merges with

water. It protects the clothes and provides fragrance too.

RECOMMENDATIONS FOR THE TOP FIVE DETERGENT BRANDS

Some of the popular brands of detergents used in America are

Tide with Bleach Alternative- This detergent is found to be costlier than other detergents

but ranks first due to the removal of tough hard stains and odor removal. The detergent is

professionally tested and has gained many good reviews from the customers.

Great Value Ultra-The washing detergent is little cheaper than compared to Tide. It

removes stains to certain extent. The detergent has gained popularity due to the low price and

it is generally suitable for normal clothes.

Cheer color guard HE-This is a highly concentrated soap and it is recommended for usage

in front loading washing machines and high proficiency top loaders mostly. It has a color

guard and works well on stains.

Page 27: Project Report "Peddling Washing Machine"

Seventh Generation Free and Clear-This detergent is an eco-friendly detergent and it is

made out of vegetable oils instead of petroleum products. The detergent is friendly to the

environment and gentle to the clothes. Acts well on stains and provide good fragrance.

Cheer Free and Gentle- This is a mild detergent and the usage of chemical is also very low

in this case. It is suitable for babies and children. The chemicals are harmless and do not

react upon the skin of the babies.

4. PEDDLING WASHING MACHINE:

Mission:

“To support the basic family economy, through the design and distribution of

bicycle machines, providing an efficient alternative for the rural development of

India.”

Page 29: Project Report "Peddling Washing Machine"

It all started around 3 months ago, we are going around scrap yards, local dumps, and could not

believe how much was being wasted. So we thought about trying to make something out of waste

washing machines.

A washing machine that was eco friendly also helps get you fit so we built the pedal powered

washing machine. It took about twenty weeks tinkering in the evening and many failed attempts to

start with. But after a few attempts we noticed that the machine wanted to build itself so we worked

with it, and after each hurdle we faced we just sat down and looked, and out of the blue the problem

was solved this carried on for quite a while so you could say the machine built itself.

20

The workings of the washing machine are so simple. All you need is an old washing machine to strip

down, just the drum and shocks, we made a frame for the machine to sit on.

We made a frame for the bike to sit on using the brazons on the bike connected the whole machine

together and it worked!

This could help many people in developing nations, eco villages, conserve water, and of course get

you fit.

Page 30: Project Report "Peddling Washing Machine"

5. BACKGROUND

5.1NEED

In developing countries, rural women are among the least privileged. Women are both essential to

The family unit and integral to the economy, yet they rarely have equal opportunities for education,

Career development or social status when compared to men. One factor behind the inequality is the

long list of responsibilities that traditionally fall to Women. Not only do women perform agricultural

duties and care for livestock alongside men, but Women are also responsible for many domestic

chores. Usually, new technology improves people Efficiency, but women benefit less from new

technology for several reasons. First, women’s duties Are neglected by technological improvement

efforts because domestic chores are often seen as cultural Obligations for women so little effort is

expended to diminish them. Second, foreign aid in the Form of appropriate technologies is unevenly

distributed because women are often considered less technically competent than men. Factors like

these tend to prevent the development of improved Technology for women’s uncompensated, time-

consuming, and laborious tasks. Our team intends to directly address the plight faced by women by

developing a pedal-powered Washing machine. . The success pedal power is effective and applicable

To their community. Women’s cooperatives that use a pedal-powered washing machine that would

allow them to spend more time on profitable tasks and less time doing chores. An Average woman

may do two to three loads per week for a family of about five children and her Husband. It generally

takes at least 8 hours of washing time, not including the extra time needed to Walk to the public

washing reservoir or hang up clothes to dry.

21

Additionally, while washing clothes By hand, women spend hours leaning over a concrete basin.

Clothes are washed by laboriously scrubbing each section of cloth over a cement washboard with

their hands immersed in detergents

Those are harmful to the skin. A pedal-powered washing machine would allow women to wash

clothes faster and with less Strain. When asked what they would do with their free time, women said

that they would try to

Generate income by making crafts or food to sell. Young daughters who help their mothers with

Domestic chores may also have the opportunity to concentrate more on their studies. Laundromat

Page 31: Project Report "Peddling Washing Machine"

Micro-enterprises may even arise if our washing machines are successful. Conditions vary in

Developing countries, but women in many regions are washing clothes manually while they could

Be doing more profitable or rewarding work elsewhere.

5.2 PROBLEM STATEMENTS

Women in India (Gujarat) wash clothes manually, but the detergents are chemically harmful to their

Hands and the motion of scrubbing is straining to the muscles. Our goal is to design an inexpensive

And durable pedal-powered washing machine for use in rural areas to gently wash clothes. Due to

Cost constraints, the washing machine is to be shared among several families or can be used by a

Local entrepreneur to run a laundering service. The washing machine must be easy to build and

Maintain locally with local materials, easy to operate (minimal required steps), and easy to power by

women or children. It must also be more comfortable to use than manual methods and culturally

Acceptable in India.

22

6. DESIGN SPECIFICATIONS

The most important aspect in the design of the machine is its ability to perform as a

device that eases the task of washing clothes. In order to be a viable solution in rural areas, the

machine should be able to deliver the same quality of washing without adding excessive overheads

(in terms Of water use, clothing wear, effort required to operate, etc.). Thus the design and operation

of the Machine should be firmly grounded in the physics of clothes washing, with a special emphasis

Page 32: Project Report "Peddling Washing Machine"

on the mechanical aspects (since water temperature and detergent composition are likely to vary).

The group also identified a number of secondary goals with varying degrees of importance that

could help make the machine more useful and thus more successful. The ability to spin-dry clothes

would increase water economy by requiring fewer wash cycles, and could relieve the strenuous task

of manually wringing the clothes before they are hung to dry. If the layout of the machine allowed

the user to perform manual work (hand-craft, food preparation, etc.) while pedaling, we could further

reduce the amount of time consumed by washing. A number of safety features should also to be

included in order to mitigate the inherent safety issues involved in a chain-driven machine. If the

machine was to be used in a home, insuring its portability of would allow it to be shared among

families, transported close to a water source for operation, or used in households where space is

limited. Another set of specifications for load sizing, water usage and pricing, depend on the targeted

Community. Since we are expecting the amount of laundry to vary between families, an initial size

was selected based on existing washing machines, and designs allowing for easy re-sizing were

preferred.

ANALYSIS:

• Cleaning:

Machine-washed clothes must be as clean as those hand-washed for 5 minutes [color]

24

7. DESIGN ALTERNATIVES:

The team evaluated a number of mechanisms that could serve as the basis for the washing machine.

Initial concepts were developed starting from the mechanical requirements of laundry washing, with

inspiration drawn from existing and historical washing machines. Refer to the Appendix for

diagrams of the design alternatives.

Page 34: Project Report "Peddling Washing Machine"

• Vertical-Axis Agitator:

The usual washing machine found in American homes consists of two vertical-axis concentric tubs.

The inner tube, which holds the clothes, has densely-spaced perforations which allow the water to

run in and out easily. Soap and water are kept inside the outer tub during the was cycle. A central

agitator alternating directions induces friction between the clothes to mechanically remove dirt and

stains. For the spin cycle, water is emptied from the outer drum and the inner drum is spun to

centrifugally extract water from the clothes.

25

• HORIZONTAL-AXIS TUMBLER:

Page 35: Project Report "Peddling Washing Machine"

Commonly used in European homes, this washer also uses two concentric tubs, however their

revolution axis is horizontal. Instead of using an agitator, the horizontal washer utilizes fins along

the inner barrel that lift the clothes on the side of the drum, and let them fall back in the water on top

of other clothes. Cycling the clothes through the water in this fashion eliminates the need for rapid

changes in the direction of rotation of the agitator, which results in lower energy requirements. Since

the drum is only filled up to one third with water, the machine realizes a sizeable water economy.

Crank-shaft piston:

Rather than using rotational motion to agitate the clothes, we were considering

using a crack-shaft to convert the rotation of the pedals to vertical translation of a piston. There are

several possibilities for the piston design. The clothes can be held in a container with holes that is

plunged into and out of the water. The piston can also be a solid block pushing the clothes

underneath it through the water. Two plates with holes could hold clothes between them as they

plunge in and out of the water. We did not select this design because it seemed inefficient to convert

the rotation of the pedals into vertical motion since commercial washers operate on rotational motion

already.

26

• TILTED-AXIS TUMBLER:

Page 36: Project Report "Peddling Washing Machine"

A tub spinning at a inclined axis using a helical fin would perform the same kind of action, in a

fashion similar to a cement mixer. The tilted design would allow for easier addition of water and

clothes. No known commercial washers use this mechanism. Manufacturing of the helical fin proved

to be problematic, and the other construction benefits we were hoping for in the tilted axis design did

not end up materializing themselves. No conclusive cleaning experiments were performed using this

design.

• Pressurized Bubbler:

A rather new concept is pressurizing air and bubbling it forcefully through the

clothes. This may lift the dirt off the clothes without requiring them to be scrubbed against one

another. Heated water has also been shown to increase cleaning efficiency. Since this idea is not

common in commercial washers, we thought it would be too risky to base our prototype on it

without having a good understanding of the cleaning mechanism or how to implement it with cheap,

available, easy-to-maintain components.

27

8. FINAL DESIGN CHOICES:

Page 37: Project Report "Peddling Washing Machine"

Our final design resembles a commercially available horizontal axis washer. The inner drum which

holds the clothes is currently constructed by modifying a plastic utility tub. Tubs like these are

widely available in anywhere, but could easily be substituted for other types of buckets, perforated

sheet metal or mesh, depending on availability. The inner drum is perforated, so that spinning the

drum will extract water from the garments. There are also three triangular fins inside the inner drum

that agitate the clothes during the wash cycle. The main structure of the machine consists of a simple

tube frame. The frame can be built by modifying an existing bicycle frame. The inner drum is

mounted on one side of a pedal shaft. Rotational force turns the drum via a drive gear attached to the

opposite side of the pedal shaft. A bicycle chain connects the gear at the drum to a set of pedals

mounted on the it’s frame.

The pedals are mounted close to the ground so that the operator can pedal the machine while seated

In a regular chair. There is an outer barrel that surrounds the inner drum and contains all the water.

In our current design, the outer barrel is constructed using a common plastic oil drum. The operator

loads and unloads clothing from the inner drum through a cutout on the side of the outer barrel. The

operator drains the soapy water and rinse water by opening a drain value at the bottom of the barrel.

A convenient feature of the peddling washing machine is the optional table mounted above the

structure. The operator can use her hands to do manual work like weaving while pedaling the

machine. Women are expressed interest in this particular feature.

28

9. PART OF THE WASHING MACHINE:

9.1 SHAFTING:

Page 38: Project Report "Peddling Washing Machine"

Here we are using a iron-hollow shafting. It is a main base for the mounting the flywheel, fins and

both the drums. It is shown in figure .first of all when we applying the pedal this shafting is rotated

by means of chain drives.

9.2 GEARING:

The machine uses a regular mountain bicycle transmission which can provide gear ratios between

1:1 and 3.5:1.

29

The user is expected to turn the pedals of the machine at about 60 rpm for the wash Cycle and a

higher 80 rpm during the dry cycle, where the lack of resistance from water makes Pedaling easier

(continuous pedaling is not necessary in this case). With a inner drum diameter of 19in, at a 1:1 gear

Page 39: Project Report "Peddling Washing Machine"

ratio, pedaling at 60rpm results in a centripetal acceleration on the clothing of about 0.87 g, which

results in efficient clothing tumbling. For the spin cycle, the user would switch to the highest

available gear, and a pedal speed of 80 rpm results in an acceleration of 18.5 g. This has been shown

to extract 50% of the water from wet cotton clothing (remaining water weight in clothing is

approximately 90% of the dry fabric weight - comparable to commercial vertical axis washing

machines).

9.3 BEARING:

SLIDING BEARING AND ROLLING BEARING:

Bearing are used as a mechanical component to transfer the power and to move a certain part, and is

done by utilizing the small frictional forces of the bearing, which makes rotates easily withstanding

the force and weight load acting against them.

30

Bearing house be classified into two major groups, namely, sliding bearings and rolling bearings,

depending on their friction type.

Page 40: Project Report "Peddling Washing Machine"

Three types of bearing are shown in fig. and ball bearing has balls between inner ring and outer ring

and roller bearing has rollers instead of balls. Either balls or rollers of rolling bearings serve the

same purpose as the lubricating oil in the sliding bearings.

Rolling bearing have some advantages as listed below, compared with the sliding bearing.

Because bearing specifications are standardized internationally, most rolling bearing are

interchangeable, and could be replaced easily with the made by different manufacturers.

Surrounding structures of a bearing could be simplified.

Easy to diagnose and maintain.

Comparatively easy to be used even under the high or low temperatures.

The rigidity of bearing could be increased by applying preload.

9.4 FLYWHEEL:

Here we are using a 20 teeth back wheel of the cycle flywheel. It is attached with the shafting and

another end with the cycle big flywheel by means of chain drive. It is shown in figure.

31

9.5 FINS:

Page 41: Project Report "Peddling Washing Machine"

We are using an opposite shaped fins to creates the turbulence inside the drum water and cloth. We

are using second hand fins of the A.C. It is attached with the shafting by means of gas welding.

When we applying the pedal shafting is attached by means of flywheel there for fins also rotated

with the shaft in the drums.

9.6 DRUM:

32

Here we are using a galvanized drum. First of all we are thinking about the plasting drum, but after

practice we are failed. Then we decided the used heavy structure drum of the galvanized drum both

Page 42: Project Report "Peddling Washing Machine"

inner and outer. Drum is shown in figure. It is a main important part of the peddling washing

machine because of all load of water; cloth is rotated by with drums. So it’s required heavy structure.

9.7 WATER USAGE:

The diameter of the outer tub is 23 inches, and depth 22 inches. Our machine is not optimally

efficient in terms of water use, since the plastic construction of the inner drum required larger

clearance between the two tubs in order to prevent contact during the spin cycle. The front of the

Outer drum also extends considerably past the front of the inner drum to provide easy access for

Clothes. With approximately 1/3 of the capacity of the outer drum filled with water, the machine

requires about 10 gallons of water. Total water usage for one load of laundry adds up to

approximately 20 gallons, half of which is used for the wash cycle, while the other half is used for

the first rinse cycle. The water from the second rinse cycle, containing just soap, can be reused for

washing the next laundry load. We expect that clever design would allow for sizeable reduction in

the water Requirement in the next prototype.

33

10. WORKING OF PEDDLING WASHING MACHINE:

Page 43: Project Report "Peddling Washing Machine"

The main important thing is how the pedal powered washing machine works?

Here after manufacture we are starting a working of the peddling washing machine. First of

all open the both the door of the inside and outside drums. Then put up the cloth in the drum.

After put up the cloth according to requirement put the 5 to 10 liters water and the washing

powder.

Now close the both the door. And sit on the cycle and starting up to applying a pedal with

slowly .After 15 to 20 minutes applying the pedal stop the applying the pedal and see what’s

happens. Then removes the inside water with the help of below pipes in the one doll or other

objects. After removing the water apply the some pedal its gain the heat inside the drums and

its help into the drying the cloth. Then remove the cloth from the drum.

12. EASE OF USE:

It is easy to use by younger and older women. After loading the machine, Washing requires three

cycles. Between each cycle, the drum spins quickly to draw the water out Of the clothing, as it drains

out of the drum. In the first cycle, water and detergent are added to the drum. The operator pedals the

machine for roughly 25 minutes, spins, and drains the water. The next two cycles are rinse cycles. In

each rinse cycle, the operator pours clean water into the Machine, pedals for 10 minutes, spins,

drains the drum. After the last rinse cycle, the operator Spins the clothes dry and saves the slightly

soapy water for the next wash cycle. Our research into existing washers and our earlier prototypes

indicate that the power required for washing and spinning is relatively low. We demonstrated that it

is not difficult to spin a perforated Plastic drum up to extraction speeds with clothes inside. For these

experiments, we used a Geared transmission from a bicycle. Both younger and older women can

generate enough power for the wash and spin cycles. We Estimate this power to be 50-75 watts.

While familiarity with pedaling in general and the machine In particular will reduce the effort

expended by the user, no prior experience will be necessary for

Its operation. The ability to change gearing ratios will allow some level of tuning to individual

Users and also allow for shorter wash times with more power input or conversely less strenuous

Operation if the user can pedal for a longer amount of time.

13. JUSTIFICATION:

• EFFICIENT:

It is much more efficient to wash clothes using than to use the manual washing tanks. It’s also

requires less energy when compared to vertical axis washing machines. The horizontal axis of

rotation uses less power because it rotates continuously without changing directions. The operator

does not need to combat the momentum and drag forces of a barrel full of water. The operator does

Not need to lean over the washing tank and submerge her hands in the soapy water. Instead, the

operator sits on the seat and pedals most of the time. She only needs get up to load the machine,

change the water and unload the machine. This leaves her hands free to work on making crafts and

keeps them out of the harmful detergent.

37

Page 47: Project Report "Peddling Washing Machine"

• EASY TO BUILD AND MAINTAIN:

Unlike any of the other alternatives, its uses locally available materials or recycled bicycle parts. It

can be produced in any area that has prevalent bicycle technology and things like plastic buckets.

Since the parts are widely available, it can serve as a basis for local entrepreneurs to start

microenterprises which would stimulate the local economy. Another advantage of using locally

available parts is that easy to repair. It is mechanically simple enough that any bicycle repair shop

would be able to service the pedal-drive.

14. CRITIQUE OF PROTOTYPE:

• INNER BARREL INSTABILITY:

The inner barrel was cantilevered from a rotating shaft supported in a bicycle bottom bracket. Since

the plastic was so flexible, the inner barrel distorts quite a bit during rotation and needs a large

clearance within the outer barrel to avoid collisions. Frequent use would probably lead to fatigue

failure of the bucket, shaft, or bearing.

38

Page 48: Project Report "Peddling Washing Machine"

• VIBRATION:

Our structure of our initial prototype was made primarily out of wooden planks bolted to each other

and the frame because we wanted it to be easy to disassemble for design changes, and light for

portability. However, using removable fasteners increases the assembly time and leaves possibilities

for tampering since the machine is used in public spaces. Also having a light-weight structural frame

makes it difficult to prevent vibrations during the spin-dry cycle when clothes may gain a centripetal

acceleration of up to 20G. We had been putting removable 50lb weights on the structure to allow it

to remain portable, but the final design should have the weight incorporated into its structure so it

will not be misused.

15. NEXT STEP

15.1 NEXT GENERATION PROTOTYPE

• DOUBLE SUPPORTED INNER BARREL:

The inner barrel will be supported at both ends fixed to a rotating shaft. Since the first prototype had

one open end to allow for side-loading, alternative loading mechanisms must be designed. One

option is to have a trap door in both the inner and outer barrels. Another is to make one of the

support for the inner barrel movable so that the inner barrel can still be opened and accessed from

the side.

• WELDED STEEL STRUCTURE:

To reduce the assembly time and prevent others from tampering with it in public areas, the structure

will be made out of welded angle iron. Welding fixtures may be designed to make it easier to weld

several structures with proper alignment of components. The welded structure will add to the weight

of the machine, making it inherently less likely to vibrate. The steel structure may also be cemented

into the ground to ensure stability and security of the machine from theft.

39

Page 49: Project Report "Peddling Washing Machine"

• DIFFERENT MATERIALS FOR OUTER BARREL:

We are considering using a steel oil drum so it can be welded directly to the structure. Welded

attachment points would not require any bolt holes that need to be sealed. The oil drum may also be

shortened by cutting off the end, and welding on a steel lid. Steel would also be more rigid than the

plastic drum we used for the initial prototype, so it would be easier to align the barrels and avoid

collisions during rotation. We are also considering using a cement basin that has the structure

incorporated into it. This would make the machine much easier to manufacture because most of the

machine would be a single intact piece.

• STEERING COLUMN OR INDUSTRIAL BEARINGS:

Since we does not currently have a use for the steering columns they receive, it would nice to

incorporate it into the washing machine design so the component would not go to waste. Industrial

bearings are also available everywhere. If we find that bicycle bearings are not suitable to support

the load, we may use industrial bearings with greater tolerances and load capacities.

• EXTEND BARRELS AXIALLY:

We are assuming that extending the barrel axially will not greatly increase the effort that must be

exerted to rotate the barrel. Having longer barrels would increase the capacity of the machine and the

amount of clothes that may be washed at one time. There are possibilities for dividing the outer

barrel so that there are two compartments, which would allow for washing to occur on one side and

rinsing occurring on the other with the same shaft rotating two separate inner barrels.

• FAUCET DRAIN SPOUT:

To maximize the ease of use, we will use a faucet spout rather than a rubber stopper so the outflow

of water can be better controlled. Leakage may be less of a concern if there was a fixed spout rather

than a removable stopper which could be easily lost or may not fit properly after repeated use.

16. ADVANTAGE AND DISADVANTAGE:

ADVANTAGE:

Having a washing machine will make you forget about Laundromats. If you buy one, you will have

enough freedom to wash clothes when you need to with comfort.

The greatest washing machine's advantage is time. Just think about all the things you could be doing

while clothes are being washed. Although prices are high, your time is precious. Specially, if you are

with your family or performing activities you like.

If you have your own washing machine, you can determine what kinds of washing procedures you

need for each piece of cloth and you do not need other people to do it for you.

• Uses less water, power, and soap

• Cleans as well as commercial washer with similar capacity

• Spin dries so no wringing needed

• Comfortable to use

• Enables women to do more rewarding things

• Technology for women

• Community investment that also benefits the poor

• Sustainable with local production and maintenance

• Replicable anywhere with bicycles

• Save the water.

• It is a non-polluting, as well as not using any types of electricity.

• Also we get the advantage of exercises with washing the cloth by means of applying the

pedal.

Page 51: Project Report "Peddling Washing Machine"

DISADVANTAGES:

The washing machine needs detergent, and water. This means an increase of consumption

and expenses in your house. If you are about to buy a washing machine, you should bear

these items in mind as future expenses and analyze your economic possibilities.

The washing machine occupies too much space. If you generally change spaces or live in

small apartments, having a washing machine will be a disadvantage for you to move around

and for the machine too.

From the above project, it can be concluded that the “peddling washing

machine” is a very simple yet very powerful design of washing cloth which if

brought into application in the rural areas of the developing countries can aid a

lot of plight and the suffering of the poor peoples who find it very difficult to

wash cloth by means of hand. Thus it is used as a application keeping in mind

the social welfare of the peoples of the rural areas. Also It is safe in working condition

and hence it does not require any safety guards during operation. The cost of maintenance is a low
