Radiator, in Particular for Heating a Glass-Ceramic Hot Plate

摘要

The invention relates to a radiant heater, in particular for heating a vitroceramic hob (ceramic hob), having a surface which carries an electrical heating conductor, this surface being the top surface of an insulation body which comprises a bearing layer and/or a heat-insulating microporous insulation layer, and having a shell-shaped enclosure which surrounds the insulation body in an annular manner. The radiant heater is characterised in that the bearing layer and/or the enclosure and/or the microporous insulation layer contains a highly porous fibre-free inorganic material, for example vermiculite. A particularly preferred configuration provides a fibre-free radiant heater.
