Temperature detection device for an electric radiant heater

An electric radiant heater associated with an active sensor for detecting the positioning of a cooking vessel on a hotplate covering said radiant heater, said radiant heater comprising:

• said active sensor having at least one sensor loop with electrically conductive material positioned in the vicinity of at least one heating zone of said radiant heater, said heating zone heatable by electric radiant elements;
• a temperature signal-emitting temperature sensor;
• a support for at least one electrically active element of said temperature sensor, wherein said support is constructed of at least one portion of said sensor loop;
• wherein at least one portion of said sensor loop comprises a functional component of said temperature sensor;
• and
• wherein said temperature sensor is a thermocouple.
