ABSTRACT:
A control device for controlling the heating capacity of the heating element of a cooking or heating plate, on which a cooking vessel, roasting vessel, or the like, can be placed and heated. The temperature on or in the cooking vessel is determined by means of a temperature sensor, conveyed to a logic circuit, and used in this for the control of the heating element by means of an output stage in dependence on the actual temperature determined and/or the temperature increase in the heating phase. In order for control of the heating output of the heating element to also be performed during a roasting process with a roasting pan placed on the cooking or heating plate, a program selection switch provided to select between various cooking processes, such as rapid simmering, steaming, warming and the like has a coordinated switching position for each and for a roasting process has an additional switching position. The heating output is controlled during the heating phase by means of preset programs of the logic circuit by switching the heating element on and off by means of the output stage in dependence on the actual temperature detected by means of the temperature sensor and/or the temperature increase detected from the temperature curve.
