Oven thermostat

摘要

An oven control for self-cleaning ovens provides a hydraulic sensing system having a wafer-like bellows. The position of the bellows is adjusted by a face cam on a control shaft in the BAKE and BROIL modes of operation. The bellows also controls the temperature of the oven for SELF-CLEANING. However, the face cam does not determine the SELF-CLEANING temperature. A door lock operator switch is also operated by the bellows, but is connected so that the adjusted position of the bellows does not affect the door lock operating temperature. Three separate calibration adjustments are provided. The first calibrates the operating temperature in the BAKE and BROIL modes of operation. The second calibrates the SELF-CLEANING temperature, and the third calibrates the door lock operating temperature. A bimetal ambient temperature compensator is provided to compensate for variations in the ambient temperature of the control.
