Abstract
An electric rice cooker is disclosed which has a cooking pot or kettle for containing rice and water, an electrical cooking heater provided adjacent to the outside surface of the kettle for heating the kettle and its contents, a thermal insulating frame structure including a removable lid member, and a kettle temperature measuring device including a thermally sensitive resistor. A connection failure of the thermally sensitive resistor is detected after a specified time interval has lapsed after starting the cooking operation. The detection is carried out in accordance with a decrease in level of the output from the kettle temperature measuring device, thereby stopping the supply of power to the heater and at the same time informing the operator of the connection failure.
