Abstract
PURPOSE:To increase the safety, by causing a heating energy supply means to be in the undriven state when means for setting an intermittent infrared introduction path to an infrared sensor is in trouble. CONSTITUTION:A microcomputer 30 for controlling a coocker outputs a digital code corresponding to the desired cooking temperature inputted from a key board 31, and a digital-analogue converter 32 output a voltage corresponding to that code. A comparator 33 compares the output voltage of an adder 24 with the output of the digital-analogue converter 32, and sends an output signal to the microcomputer 30 when the former becomes greater than the latter. Thus, the driving of the heating energy supply means 34 is stopped. An abnormality detecting means 36, when pulse-like synchronous signals outputted from a synchronous signal output means 13 are not pulses, detects them, and inform the fact to the microcomputer 30. Based on this, the microcomputer 30 stops the driving of the heating energy supply means 34.
