子レンジ。 A heating chamber having an air intake port, a microwave oscillating unit as a first cooking heat source, a heater as a second cooking heat source, a blower device, the air intake port being opened and closed, and when the air intake port is opened, the air generated by the air blower device is A damper that causes air to flow into the intake port, a cam motor, a cam that is rotationally driven by the cam motor and places the damper in a fully closed or fully open state at a predetermined rotational position, and a cam that changes the damper from a fully closed state to a fully open state based on a fully open signal. a motor drive circuit and a control unit that energize the cam motor in order to change the damper in the opposite direction and stop it in the fully open state, and change the damper from the fully open state to the fully closed state and stop it in the fully closed state when the fully open signal disappears; The control unit selectively drives and controls the microwave oscillation unit and the heater, and also controls the blower when both are driven, and the control unit further controls the microwave oscillation unit and the heater. The full-open signal is continuously applied to the motor drive circuit during almost the entire drive period of the oscillation section, and when the heater is driven, at the initial stage of the drive,
A microwave oven characterized in that the fully open signal is applied to the motor drive circuit only for a period of time approximately equal to the time required for the damper to change from a fully closed state to a fully open state.
