Table of Contents

In case satisfactory cooking of rice is not accomplished (excessively overdone), conduct the temperature test

in accordance with the following procedure.

Simpliﬁ ed Testing Method. (Simulated Rice-Cooking)

1. Testing conditions

a. Power voltage 220V.

b. Fill inner pot with 80 ml. of water. (Water temperature to be the same as ambient temperature.)

c. Ambient temperature to be 20 to 30

d. JAR RICE COOKER to be sufﬁ ciently kept cooled. (Cooker body temperature to be the same as ambient

temperature.)

e. Never fail to set the inner lid.

2. Testing procedure

a. Fill the inner pot with 80 ml. of water turn ON the cook switch (for cooking purpose) to energize the

cooker, and measure the time for cooking.

b. When steam comes out of the steam vent, open the upper lid and check the bubbling state on the

bottom of inner pot. (Check if the inner pot is allowed to be in close and stable contact with the heater

plate. Conduct checking within a short period of time so as not to inﬂ uence over the operating time.)

c. Where the bubbling state is satisfactory, close the upper lid again and energize the cooker.

3. Judgment criteria

During the course of the simulated cooking with water conducted under the conditions as above, if meeting

the following requirements, will be considered acceptable.

a. If the bubbling state is such that bubbles occur evenly around the bottom of inner pot as shown in

Fig. 19(A), the inner pot is satisfactorily in contact with the heater plate. Where bubbles do not occur more

than 1/3 of the bottom periphery as shown in Fig. 19(B), contaminant deposits on the heater plate or

deformation or damage on the inner pot may be existing. (Though such containment deposits can be

removed by cleaning, the inner pot deformed to the extent hardly rectiﬁ ed should be replaced with new

one. The same applies to the heater plate deformed.)
