PURPOSE:To provide an automatic suitable finishing of the foodstuff irrespective of the material to be cooked, and weight of the foodstuff and power voltage by a method wherein a heating time for the grill is corrected in response to a variation in time of the input signal of the thermistor for a discharging gas temperature in the oven. CONSTITUTION:Gas sensor 7 and the thermistor 8 are connected to DC power supply 11 through a load resistance, and the terminal voltages in the gas sensor7 and the thermistor 8 are fed to the CPU of the microcomputor 15 through A-D convertors 12, 13 and an interface 14. Key signal on the panel 1 is also fed to the microcomputor 15 through the IF 14. Magnetron 9 is operated through the contact point 18 of the relay 17, door switch 19 and a voltage increasing transformer 20 etc. The heater 10 is operated through the contact point 24 of the relay 23 and the switch 19 etc. The relays 17 and 23 are controlled under an instruction from CPU through IF 14 and the transistors 21 and 25. |
