Connectionless food steamer with automatic electric steam trap

摘要: A connectionless steam cooker has an insulated housing that surrounds internal cooking compartment accessible through a door. supply of water is held in the and immerses plate-like heating element mounted at floor, preferably electrical resistance type. outlet located above maximum level fluid communication with adjacent electrically-operated solenoid valve normally open to atmosphere. temperature sensor close physical proximity closes wherein sensed or set level. The also connected pair column pressure-responsive microswitches. One microswitch controls power element. It closely, e.g. cycle between ON OFF response pressure range 1 3 inches W. C.) second responds higher (e.g. 9 indicative unsafe over-pressure vent tilt respect horizontal Two heat-sensing elements are secured on upper lower portions tilted heater plate, diagonally opposite comers. sensors each produce output alarm signal when region not immersed water.
