  • Patent number: 3979573
    Abstract: A microwave oven has an up-opening oven door which is hinged to be movable in an arcuate path. The door moves between a closed lower position covering an aperture to the cooking cavity in the front surface of the oven cabinet and an open upper position above the aperture. The axis of this arcuate motion is adjacent the upper edge of the oven door and internal to the oven cabinet. Connecting arms extend from pivots within the cabinet through openings in the front surface of the oven cabinet, and connect to the oven door. The front surface of the oven cabinet above the aperture is recessed such that the oven door may be opened substantially beyond a horizontal position to provide access to the oven cooking cavity.
