PURPOSE:To reduce irregularities in finish, by calculating an additional heating period from an initial microwave heating period and the period of time elapsed from the moment microwave heating subsequent to convection heating is started to the moment an output from a gas sensor reaches a predetermined level. CONSTITUTION:The first period to time elapsed from the moment the first microwave heating by a microwave oscillator 2 is started when starting cooking to the moment an output signal from the gas sensor 7 reaches a predetermined detection level is stored in a microcomputer 49, and after the first period of time is elapsed, the first microwave heating is stopped, and then hot-air circulation heating by a heater 9 is conducted. The second period of time elapsed from the moment the second microwave heating subsequent to the hot-air circulation heating is started to the moment the output signal from the gas sensor 7 reaches a predetermined detection level is stored in the microcomputer 49, which calculates an additional heating period from the first and second periods of time, and the second microwave heating is conducted until the additional heating period is elapsed. |
