ABSTRACT:
An air circulation system for a microwave oven is provided which includes air inlet openings in the front wall, bottom wall and rear wall of the oven cabinet to cause air to flow over the various electrical components within the oven cabinet prior to passing through an air blower. All the air passing through the blower passes over the magnetron for cooling purposes and then the air flow is split into three air streams, one air stream passing through the cooking cavity for removal of humidity, a second air stream passing through the cooking cavity above a protective cover for cooling a light bulb and a third air stream passing directly out of the oven cabinet. The air outlets are provided in the front wall of the cabinet to avoid the necessity of providing a separate air ducting system if the oven is mounted in a recessed or built-in manner. An air baffle is used within the cabinet to keep the third air stream separate from the air streams which have passed through the cooking cavity.
