Abstract

A modulated steam cooker in which food to be cooked is received in an oven chamber having an access door associated with a door switch, steam being fed directly into the oven by a steam generator having an electric heater immersed in a pool of water. The heater is connected through the door switch to a power source whereby the generator is powered only when the door is shut. The pressure of steam draining from the oven is sensed by a pressure-responsive switch interposed between the heater and the power source, the pressure switch intermittently interrupting the power supplied to the heater only when the sensed pressure exceeds a predetermined level somewhat above atmospheric pressure, thereby modulating the generation of steam supplied to the oven as a function of the quantity and temperature of food therein to effect efficient cooking of the food. Mounted on the steam generator is a spray head supplied with water only when the door is opened. The head then emits a spray of water which quenches the steam in the generator, the resultant pressure drop causing steam to be sucked back from the oven into the steam generator whereby little steam escapes from the opened door and the person opening the door is not subjected to hazardous steam.
