Abstract
A microwave oven comprises a double-walled housing structure and a hingedly supported door and a door interlocking mechanism for locking the door in locked position to close an access opening communicating to the interior of the microwave oven. In addition to a switch operatively coupled to the interlocking mechanism, which is closed upon closure of the door, a detector device is provided for rendering the high frequency wave oscillator inoperative when the door in the locked position is to be moved from the closed position towards the opened position by the application of an external pulling force thereto or when a foreign matter is jammed in between the door and the front of the microwave oven. The detector device may comprise any of a detector switch, which may be in the form of a microswitch or a pressure sensitive element, or a pivotable lever.
