Abstract
A description is given of a temperature detection device for an electric radiant heater, with which is associated an active sensor for detecting the positioning of a cooking vessel on a hotplate, particularly a glass ceramic plate, covering the radiant heater. This sensor is part of an inductive resonant circuit of a control means and preferably has a single sensor loop of electrically conductive material located in the vicinity of at least one heating zone heatable by electric radiant elements and preferably partly overlapping the same. According to the invention, with at least one portion the sensor loop forms a functional element of a temperature sensor of the temperature detection device. For example, a tubular sensor loop portion can serve as a supporting or protective jacket of a jacket thermocouple.
