Abstract
A microwave cooking apparatus includes a cooking chamber and a reflecting chamber disposed on the cooking chamber. The reflecting chamber is provided with a rotatable reflector for reflecting microwaves from a magnetron. The cooking apparatus further includes a fan device for producing cooling air, and a duct device directing a portion of the air to the reflecting chamber for rotating the reflector, and by-passing the reflecting chamber and directing a portion of the air to the cooking chamber for ventilating the cooking chamber. This construction may provide sufficient air to the reflecting chamber and the cooking chamber.
