Abstract

PURPOSE: To eliminate the influence of the fluctuation of a power source voltage upon finishing of foods, by detecting the fluctuation of the power source voltage and by correcting the heating time on a basis of this fluctuation.
CONSTITUTION: When foods are charged in a heating chamber 3 and a prescribed heating time is set to a setter 16, a semiconductor control element circuit 2 is turned on. Next, when a heating start button is depressed, a latch switch 20 is closed, and a counter 15 starts subtraction simultaneously with the start of heating of a heater 4. Meanwhile, the voltage of an AC power source is generated as a proportional DC voltage in a resistance circuit 7 through a detecting transformer 5 and a rectifying circuit 6. This DC voltage is converted to a digital value E1(t) by an A/D converting circuit 8 and is inputted to a subtracting circuit 9, and the circuit 9 outputs the result obtained by subtracting the digital value E1(t) from a digital value E corresponding to a reference voltage. This output value is multiplied in a multiplying circuit 11 by a proportion constant and is inputted to a counter 12. When the counter 15 becomes zero the counter 12 starts a time subtraction proportional to the integration of the variation of the power source voltage, and the circuit 2 is turned on during this subtraction time.
