PURPOSE:To achieve an efficient heating of food by arranging an action time control mechanism to adjust the heating time with a heater and that by a microwave heating means in such a manner that the former is less initially but becomes more with the passage of time. CONSTITUTION:A conversion table is entered into a ROM of a heating control circuit 9 beforehand to determine the ratio of action time between the heating time G1, G2, G3... with a heater 4 and the heating time M1, M2, M3... with a microtron 3 in the mixed grilling of repeating a grill heating and a range heating alternately. In this case, an action time control mechanism is so arranged so to adjust the heating time with the heater 4 and the heating time with the microtron 3 in such a manner that the former is less than the latter in the early period of starting the heating and becomes more with the passage of time by the conversion table according to the time set with the timer 8. |
