ABSTRACT:
A steam heated cooking pan comprises in combination a double-mantled food preparation vessel arranged above a steam generator which includes an outer vessel and an open bottom inner vessel enclosed in the outer vessel and in which are disposed steam generating electrodes. A steam exhaust opening is provided at the upper end of the inner vessel for supplying steam to the double-mantled vessel. Steam generation is automatically controlled by a movable cover opening and closing the steam exhaust opening in response to steam pressure sensed by a pressure sensitive member arranged below the outer vessel and coupled to the cover by an actuating rod passing through a tube secured to the bottom of the outer vessel and extending upwardly to the opening. The tube communicates the pressure sensitive member with the inner vessel and prevents contact between the water in the steam generator and the pressure sensitive member and actuating rod thereby preventing deposition of time thereon.
