Abstract
A pyrolytic self-cleaning oven has an oven door latch mechanism with an elongated latch arm that has a shifting pivot means and a tapered latch hook so the latch mechanism will cause the compression of the door gasket for sealing the oven cavity during the self-cleaning cycle. There is a locking means for the latch mechanism which functions when the door is locked and the oven temperature is above normal cooking temperatures. The locking means includes a bimetal actuator that senses the temperature of the oxidation unit in the oven exhaust system.
