  • Patent number: 7573003
    Abstract: In a cooktop with a cooktop panel, beneath which at least one heating element is disposed for heating up a cooking vessel to be placed on the cooktop panel, and with a temperature sensor for sensing the temperature of the cooktop panel, which temperature sensor is in heat-conducting contact with the underside of the cooktop panel within the heating element and is connected to a control unit for controlling the heating power of the heating element, to simplify assembly/fitting, the invention provides a heat-conducting element within the heating element in heat-conducting contact with the underside of the cooktop panel, and fastens the temperature sensor in this region to the heat-conducting element.

  • Patent number: 6753509
    Abstract: In a cooktop with a cooktop plate, in particular, made from glass ceramic, beneath which at least one heating element is disposed, for heating a cooking vessel to be placed on the cooktop plate, and having a temperature sensor for recording the temperature of the cooktop plate, which temperature sensor senses the temperature of the underside of the cooktop plate within the heating element and is shielded from the thermal radiation from a heating device of the heating element by insulating material, and is connected to a control unit for controlling the heating power of the heating element, to enable a good measurement accuracy to be achieved, the temperature sensor is in thermal contact with the underside of the cooktop plate by a thermally conductive element, and that the element and the temperature sensor are shielded from the thermal radiation of the heating device by insulating material.

  • Patent number: 6580058
    Abstract: In a cooktop having a cooktop panel, beneath which at least one heating element is disposed for heating up a vessel to be placed on the panel, and a temperature sensor sensing temperature of the underside of the panel within the heating element and connected to a control unit for controlling heating power of the heating element, to make assembly/fitting of the unit easier, the temperature sensor is fastened to an element extending from a region inside the heating element into a region outside the heating element, the element having a receiving portion inside the heating element for the temperature sensor and a fitting portion for fastening of the element, in particular, to the heating element, and/or a connection portion for connecting at least an electrical line from outside the heating element, which receiving portion lies radially offset laterally with respect to the fitting portion or connection portion.
