The display block J arranged on the right side of FIG. 3 is a temperature scale for displaying the set temperature and the cooking temperature, and the temperature corresponding to the cooking condition and the type of the cooked food displayed on the display blocks C to I is displayed. It is supposed to be done. The display contents of the display panel shown in FIG. 3 are displayed corresponding to the cooking conditions set by the function key 7.

FIG. 4 is a block diagram of the control circuit of the embodiment shown in FIG. 2, 10 is a microcomputer including CPU, ROM, RAM, I / O ports, etc., 11 is a food placed in the heating chamber 2. A magnetron that is heated by microwaves, 12 is a heater that cooks food placed in the heating chamber 2 in an oven or a grill, 13 is a temperature sensor that detects the temperature of the heating chamber, 14 is a door switch that detects whether the door 3 is open or closed, A motor 15 drives the turntable 4. Microcomputer
The numeral 10 receives the output from the keyboard 6, the sensor 13 and the door switch 14, and the magnetron 11, the heater 12 and the display panel 5 are received.
And output to the motor 15.

In such a configuration, when the food to be cooked is placed in the heating chamber 2 and the cooking condition is set by the function key 7 after the door 3 is closed, the display corresponding to the cooking condition is displayed on the display panel 5. It Next, when the start key 9 is pressed, the magnetron 11 or the heater 12 is driven to heat and cook the food according to the set conditions. The progress of cooking is confirmed by the sensor 13, and the content is displayed on the display panel 5. When the cooking under the set cooking conditions is completed, the driving of the magnetron 11 or the heater 12 is stopped. When the door 3 is opened carelessly during cooking, the door switch 14 detects it and immediately stops driving the magnetron 11 or the heater 12.
