ABSTRACT:
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.
