Abstract
A door interlock arrangement for an appliance such as a self-cleaning electric oven has an operating lever manually movable in a limited arc to move a door bolt into and out of door latching position and provide further motion to close the door very securely, and has a lock arranged in a novel cooperative relationship with an electrical interlock unit to permit certain appliance operations only when the door is latched and to permit opening of the door after the end of those appliance operations only when a selected appliance zone has cooled to a safe temperature.
