<p>A circuit for controlling a rice cooker has at least one heater used for heating a cooking pot. This circuit comprises a temperature detection element capable of detecting the temperature of the pot; a converter, connected to receive a detection signal from the temperature detection element, for converting the received signal to a specified electrical signal; a selector, connected to receive an electrical signal from the converter, for producing a first or second selection signal based on whether the value of the electrical signal is or is not within a specified range; and a display capable of displaying a plurality of cooking operation states. This circuit further includes a first controller which receives the first selection signal and supplies to the heater specified turn-on control signals for dividing the cooking operation into a plurality of states and sequentially performing each cooking operation. The controller also supplies display control signals for dividing the cooking operation into a plurality of states corresponding to the turn-on control signals and sequentially indicating these states. A second controller receives the second selection signal and supplies to the display model display control signals which divides the cooking operation into a plurality of states and displays the states.</p> |
