Radiant heater mounted with a thermal switch in a cooking hob

摘要

The electric radiant heater (101) adapted to a cooking hob is attached to the cooking plate (2a) forming with it an air cavity (13) in which the extended heating resistor (105) is housed on an insulating base (104). A peripheral outer wall (3,6) of the heater defines said cavity (13) in which there is a thermal switch (107) positioned, having a bimetal sensor (107c) the compact body (107a) of which rests on a central area (104a) of the insulating base, and its metal heat-receiving base (107b) in a position facing a heating resistor segment (105a) and either very close to or above it making contact. The relative position of the bimetal sensor (107c) enables a switching point (SWC',SWO') of the electrical contact (109) to be set in correlation to the hotplate warning light temperature range (TU).
