Oven thermostat

An oven control for self-cleaning ovens comprising a body, a first switch on said body for controlling oven heaters and controlling the oven temperature a second switch on said body for operating an oven door lock during self-cleaning, and an adjustable temperature sensor providing an output surface movable in response to changes in oven temperature, said output surface being connected to operate said first switch in response to movement of said output surface to a predetermined position, adjustment of said sensor providing adjustment of the temperature of operation of said first switch, said output surface being connected to operate said second switch in response to a substantially constant predetermined temperature independent of the adjustment of said sensor.

An oven control for self-cleaning ovens comprising a body, a sensing unit providing opposed first and second sides movable apart in response to increasing temperature and towards each other in response to decreasing temperature, a control shaft journaled on said body for rotation about an axis, a cam mounted on said shaft operating to adjust the position of said first side relative to said body, switch means on said body operated in response to movement of said second side, and bimetal ambient temperature compensating means adjusting the position of said cam relative to said body in response to changes in ambient temperature so that the operation of said switch means is substantially unaffected by changes in ambient temperature.

An oven control for self-cleaning ovens comprising a body, a first switch on said body for controlling heating means in an associated oven, a second switch for controlling an oven door lock, a sensor connected to said first switch for adjustably controlling the temperature in said associated oven sensed by said sensor within a BAKE temperature range and controlling the temperature in said associated oven at a SELF-CLEANING temperature, said sensor being connected to operate said second switch at an intermediate temperature above said BAKE temperature range and below said SELF-CLEANING temperature for controlling an oven door lock, and separate first, second and third independent calibration means, said first calibration means being connected to independently calibrate the BAKE temperature range, said second calibration means being connected to independently calibrate said self-cleaning temperature, and said third calibration means being connected to independently calibrate said intermediate temperature.
