Circuit for controlling a rice cooker with power interruption control

A circuit for controlling a rice cooker having at least one heater used for cooking rice, comprising:

• rice cooking mode setting means for selectively setting one of at least three different rice cooking modes having high, medium and low heater heating calories, respectively;
• main control means for fetching preset mode data responsive to said mode set by said rice cooking mode setting means, and for supplying a predetermined energize/deenergize control signal corresponding to the preset mode data, to said heater;
• power failure detecting means for detecting a temporary interruption of a drive power voltage to said to said main control means after the preset mode data has been fetched in said main control means, and for maintaining the detected state for a predetermined period of time;
• power interrupt recovery operation control means for fetching a detection signal from said power failure detecting means when supply of the drive voltage to said main control means is recovered, and for controlling said main control means to supply an energize/deenergize control signal corresponding to a specific rice cooking mode of a medium heating calorie to said heater;
• preset mode display means including at least three display elements which correspond to the preset mode data;
• and
• mode display control means for controlling all the display elements of said preset mode display means by fetching the detection signal from said power failure detecting means when supply of the drive voltage to said main control means is recovered.
