Abstract: A domestic range of the electric type includes a cooking platform providing a plurality of "burner" locations constituted by pancake-shaped surface heating elements formed of spirally wound resistance wire. An elongated boxlike control unit extends upwardly from and across the back edge of the cooking platform. An oven chamber of the pyrolytic self-cleaning type is located below the range platform and includes radiant-type heating elements also formed of resistance wire. A heat-sink-mounted electronic module located within the control unit is protected from damaging high temperatures caused by improper operation of the range by a pair of normally closed temperature-sensitive bimetal actuated switches mounted to the module heat sink, the switches being connected in electrical series relationship between the heating elements and their electrical power source.

Abstract: An L-shaped hooked end of a latch rod, rotatably supported by a range body, engages a door-supported cam surface as the rod is rotated on its longitudinal axis by a motor to effect oven door locking. The cam surface is fixed at and radially spaced from the center of an elongated member whose ends are fastened to the oven door. As the latch hook engages and rides the cam surface, the elongated member is placed in torsion to provide a biasing force that maintains the locked oven door in tight sealing engagement with the range body. The motor rotating the latch rod to effect oven door locking and unlocking is actuated solely by operator manipulation of the oven thermostat control apart from the oven selector and timer controls.

Abstract: A free-standing, convection-cooled domestic range of the pyrolytic self-cleaning type including heat sink means for limiting the temperature of user accessible exterior surfaces of the range body to safe levels during a high temperature, oven-cleaning operation. A pair of downwardly extending, elongated channel members having U-shaped cross sections is positioned within the range body, one under each upper front corner thereof between a respective side wall of the range body and an opposed oven liner side wall. Apertured, horizontal mounting flanges from which the channel members are hung advantageously allow for the unimpeded upward flow of convected air along the entire lengths of the heat sink channel members.
