Abstract

PURPOSE: To prevent extraodinary temperature rise of food to be cooked, by using a control system of the type controlling current supply to a heater through detection of the temperature of the food to be cooked by means of a temperature-sensitive resistance element, which has a circuit designed to be capable of stopping current supply to the heater when a trouble such as short-circuit or disconnection of wire is caused with the temperature-sensitive resistance element.
CONSTITUTION: When the temperature of a pan having therein food to be cooked exceeds a setting temperature as the pan is heated by a heater 3 and the value of resistance of a thermistor 14 serving as a temperature-sensitive resistance element is decreased with proceeding of cooking, an operational amplifier 10 produces an H-level output. Thereupon, a capacitor C37 begins to be charged, and transistors Tr40, Tr41 are turned OFF and ON, respectively. Further, a thyritor 4 is turned OFF, so that current supply to the heater 3 is stopped. Here, if the thermistor 14 causes a trouble of short-circuit, a voltage of a plus source wire 15 is impressed to a non-inverting inputterminal 16 of the operational amplifier 10, so that it produces also an H-level output and stops current supply to the heater 3.
