Abstract
A circuit for controlling a rice cooker having at least one heater used for cooking rice comprises, a rice cooking mode setting section capable of selectively setting three or more different rice cooking modes having high, medium and low heater heating calories, respectively, a main control section for fetching preset mode data set by the rice cooking mode setting section, and for supplying a predetermined energize/deenergize control signal corresponding to the preset mode data to the heater, a power interrupt detecting section for detecting a state wherein supply of a drive power voltage to the main control section is temporarily interrupted after the preset mode data is fetched in the main control section, and for maintaining the detected state for a predetermined period of time, and a power interrupt recovering operation control section for fetching a detection signal from the power interrupt detecting section when supply of the drive voltage to the main control section is recovered, and for controlling the main control section in such a manner that the energize/deenergize control signal corresponding to a specific rice cooking mode at the medium heating calorie is supplied to t…
