ABSTRACT:
A timer for an electric rice cooker includes a switch for setting the current time and a switch for setting the cooking completion time. When the operation of the current time set switch precedes that of the cooking completion time set switch, the cooking operation is started after lapse of a predetermined time period in accordance with the difference time period between the current time set and the cooking completion time set. The cooking operation is completed at the cooking completion time set. When the cooking completion time set switch is operated without preceding operation of the current time set switch so that a cooking completion standby period of time is set, the cooking operation is started after lapse of a leftover period of time, the value of which is obtained by subtracting a cooking period of time from the cooking completion standby period of time set. The cooking operation is completed after lapse of the cooking completion standby time period. The setting of the timer can be done in two ways described above according to the situation.
