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.
