Abstract
An oven latch mechanism for heat-cleaning ovens is disclosed. The latch mechanism employs a unidirectional rotating d.c. motor to automatically latch the oven door upon initiation of a heat-cleaning operation and to automatically unlatch the door after a heat-clean operation and after the oven has reached a predetermined lower temperature. The latch mechanism includes a latch arm which moves arcuately through a variety of positions. The latch member senses whether the door is open and follows a different path of motion accordingly. If the latch member senses an open door, it returns to an unlatched position.
