Abstract
An electric rice cooker is disclosed which performs auxiliary cooking such as 'twice cooking' by changing the operating time of auxiliary cooking in accordance with the actual cooking amount, immediately after the main cooking is completed. The actual temperature of a kettle which contains rice and water and which is detachably mounted in a thermal insulating frame is measured by a thermistor. Upon deenergization of an electric heater after main cooking is completed, the actual kettle temperature decreases. A time interval for the kettle temperature to go from a first temperature at the completion of main cooking to a second temperature is closely related to the actual cooking amount. The auxiliary cooking time interval is determined by a control circuit arranged in a case in accordance with the time interval described above.
