    • In a microwave heating device, a propeller fan is mounted on a drive shaft of a motor that in vertically positioned parts of a high frequency power supply unit are arranged in the order of a power control semiconductor device and a high-voltage transformer along the direction of revolution of the propeller fan. The motor is secured to a support member formed by a motor cover attached to the casing of the propeller fan. The fan and high frequency power supply unit are mounted to a first frame and a second frame, both of which are bent and connected at a connecting portion and fixed in an approximately "L" shape, while an airflow path is defined by a first guide wall and a second guide wall to cool the parts of the high frequency power supply unit. An airflow path is formed by a plurality of guide walls provided on the two frames, and a communicating hole is provided in proximity to the connecting portion of the two frames. The propeller fan is so arranged as to revolve at a low r.p.m. after stopping the microwave heating.
