摘要： 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.

摘要： A door latch interlock system for use in a microwave oven in selectively securing a closure door in a closed position across the opening to the microwave oven cavity. The structure for selectively securing the door in the closed position includes a guide on the cabinet, a slider member movably carried by the guide, catch structure carried by the slider member, latch structure carried by the closure and engageable with the catch structure as an incident of the closure being disposed in the latching position, an actuator carried by the closure for operating one of the switches of the electrical circuit for controlling delivery of electric power to the microwave energy generator of the oven to permit operation of the generator only when the door is latched in the closed position, and manually operable structure carried by the closure for arranging the actuator to cause the one switch to prevent operation of the generator and concurrently move the slider member to the released disposition. A second switch control is carried by the latch structure for causing a second of the electrical circuit switches to prevent operation of the microwave energy generator whenever the closure door is in the closed position. In the illustrated embodiment, the guide is defined by a vertical support bar. The latch structure, in the illustrated embodiment, is defined by a pair of interconnected arms pivoted from the support bar. In the illustrated embodiment, the slider member is biased upwardly to the latching position. In the illustrated embodiment, the manually operable structure includes a pushbutton connected to the door handle.
