SINGLE POLARITY OVEN CONTROL

摘要

An oven system having a heat clean cycle is disclosed that utilizes a single peak circuit having a single polarity thermal power relay. An oven thermostat is used to provide the required dialed in temperature for heat cleaning and this thermostat includes a cam arrangement actuating a movable contact which is closed for normal cooking temperatures and which is open for oven cleaning purposes. The contact is shunted in latch and clean modes to insure that the multi-terminal selector switch is set for proper oven circuitry whenever the thermostat is set for an upper temperature limit. The single polarity thermal relay is connected in series circuit relationship to the oven heaters for broil, fast broil and bake and opens upon attainment of the temperature peak utilized for cleaning purposes.
