Electrical koch under set for koch gefa se

摘要

A base containing an electric heater element and controls for supporting glass or ceramic cookware and providing automatic temperature control. The control includes a bi-metal controlled switch enclosed in a metal housing having one surface, generally adjacent the bottom of the cookware, treated so as to be highly absorptive of infrared radiation incident thereon. The bi-metal then reacts in response to the amount of radiation absorbed on that surface which is directly related to the temperature of the cookware. Other surfaces of the housing are also similarly treated to aid dissipation of the heat in the control and minimize lag time between the temperature of the dish and the temperature of the controls.
