FUNCTION OF CENTER THERMOSTAT , THERMAL FUSE

A. Center Thermostat

the cooking cycle, and starts the warming cycle.

Rod Inner spring

gilfi r (coonns Pornron) (WermlrU or Ott Podtlon) Micro switch

Refer to these figures showing the center thermostat construction and cooking position. As the metal is heated,

its abilityto be attractedbythe magnet decreases.

Finally , the inner spring pressure becomes stronger than the magnetic pull and the metal and magnet will pop apart.

The rod activates the switch lever which causes the auxiliary lever to press the micro-switch button into the warming cycle.

B. Switch-On Preventive System

Thermostat surfaceInner spring

Cooking heatetOuter springThermostat case

Cook switch button

Svvrlch lever

This is design to prevent the rice cooker from being tumed on without the pan placed into position.

1) Normally when the pan is inserted properly into the rice cooker , the pan will depress the center thermostat. The center

thermostat outer spring will be compressed. In this case when the switch button is depressed , the following will happen :

a. The auxiliary lever will release the micro-switch button. This puts the micro-switch in the cook position.

b. The switchleverwill pushthe rodwhichwill allowthe magnetto meetwiththe metal.

c. When the rice is cooked and the proper temperature has been reached I34' C r 6 " C , the metal and magnet will

pop apart as described in the center thermostat operation above'

d. The rod will push the switch lever and cause the auxiliary lever to depress the micro-switch button. This puts the

micro-switch in the warming position.

2) When the pan is not in place within the rice cooker , the center thermostat is not dqpressed.

a. In this condition , the outer spring is not compressed within the center thermostat preventing the metal from

reaching its normal operating position

b. When the switch button is depressed , the switch lever and auxiliary lever work as above but the magnet cannot

come in contact with the metal to hold the switch lever in the cook position. This happens because the switch lever

hitsthe thermostat case andccannot pushthe rod , withthe magnet attached , alltheyway upto meetwiththe metal

c. Whenthe pressure istakenoffthe switchbutton, the switchleverreleases immediatelyto the open orwarmpositions.

C. Thermal Fuse

The thermal fuse is used to open the circuit to the cooking heater when the temperature has gone unusually high.

This happens in cases such as incomplete contact between the heater and pan or if the switch button is forced to stay

on keeping the heater energized abnormally.

This fuse is not a resetting device and must be replaced after openning.

Whenever replacing the fuse make sure the protective cover is placed over all exposed wiring.

When recieving the cooker to be repaired, be sure to always take charge of not only the cooker body but also the pan

and the lid, and ask for details as to the symptom of the trouble.

Furthermore, when making troubleshooting of each part, be sure to remove the power plug from the socket.

TESTING PROCEDURE

l. Bubbling Test

Input the pan in the main body, and lightly rotate the pan clockwise and counter clockwise to set the pan on the heating

plate properly.

1. Fill water until the center area of the pan bottom is depped, and close the lid. Then turn on the boiling switch.

2. When it begins boiling to produce steam, remove the lid and immediately check the bubbling condition on the pan

bottom.

3. Bubbling condition is shown in figure 3

A. Bubbles generate through outthe circumference ofthe panbottom....... Proper

B. Bubblesdoesnotgenerateonmorethanonequaterpartofthepanbottomcircumference.....Improper

thermostat

Figure 2 Figure 3

If it is improper, it mayresult fromthe insufficient contact betweenthe panbottomandthe sheathed heater. Checkthe pan

bottom and the sheathed heater for foreign material remained. Clean up the foreign materials or replace the parts.

2. Evaporation Test

I . After satisfactory bubbling is confirmed, remove the lid and put a weight on the cooker.

2.Covertheentirepanbottomwith2or3piecesoftissuepaper(or gatze),andtumontheswitchsubsequently.

3. The cooker is consideredacceptable ifthe timingwhen steam generationcomes to a stop afterwaterof the panbottom

has evaporated, is within I minute before and after the cooking switch is turned off.

If these requirements are not satisfied, checkthe center thermostat as well as the contacted conditionbetween the pan

bottom and the cooking heater, and then repair or replace the parts.

3. Boiling control lever adjustment

Such a mechanical operation as center thermostat goes up and down is used to turn on and offthe micro-switch.

Checkand adjust this relationship as shown below.

When the boiling switch is turned on. Whentheboiling switch is turn off.

Checking The auxiliary lever presses the push-button

(Theo'Warm" larnp comes on)

The auxiliary lever does not press the push

button. (The "COOK" lamp comes on.)

Adjusting To

lainthe

above relationship, adjust the auxiliary leverbybending itwithlong nose pliers.
