Abstract: A microwave oven comprises a high frequency generator which is formed by a magnetron 5, a high-voltage transformer 6 and a high-voltage capacitor 7, and a cooling device 8 for cooling these components. The heating power of the high frequency generator is reinforced as compared with the cooling power of the cooling device, and there is such a possibility that the magnetron and the like are subjected to abnormal temperature rise if the high frequency generator is continuously driven at the maximum high frequency output. Therefore, if the user sets a heating time for quick heating at the maximum high frequency output in excess of a prescribed maximum allowable heating time of five minutes, driving of the magnetron is inhibited. If quick heating is repetitively performed, the prescribed maximum allowable heating time is corrected in time relation with preceding heating.
