Abstract
A motorized hinge system for an oven door includes first and second hinge assemblies. At least one hinge assembly is motorized. In the motorized hinge assembly, a first hinge portion is connected to the oven door and a second hinge portion connected to the oven body. A door control arm has first end connected to the first hinge portion and a second end spaced from the first end. A motor is connected to the oven body and includes an actuator that is driven by the motor. The actuator is operably coupled to the door control arm and is movable in first and second directions by the motor to move the door control arm and door in corresponding first and second directions pivotally relative to the second hinge portion. In one example, the actuator is a lead screw type actuator. A non-motorized hinge assembly is also used together with the motorized hinge assembly to connect the oven door to the body. The non-motorized hinge assembly is spring-biased to urge the door toward its closed position.
