MOTORIZED OVEN DOOR LATCH AND CONTROL CIRCUIT FOR SAME

摘要

MOTORIZED OVEN DOOR LATCH AND CONTROL CIRCUIT FOR SAME 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 therange 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.
