ABSTRACT:
A combination microwave and gas oven, in which an object to be heated is heat-treated by microwave energy and air heated by a gas burner inside a combustion chamber and forced to be circulated by a fan. A microwave introducing port to the heating cavity is covered with a heat insulating member provided with a film which can reflect the radiant energy transferred to the direction of the microwave introducing port. To prevent the leakage of microwave from the heating cavity especially related to a shaft of the fan which is connected to a driving motor located outside the heating cavity, a choke cavity for terminating leaked microwave from said cavity is provided.
