ELECTRICAL RADIANT HEATER FOR HEATING HEATING SURFACES,AS WELL AS PROCESS AND APPARATUS FOR PRODUCING THE SAME

摘要

An electric radiant heater (11) for heating a glass ceramic cooking surface (12) contains a dish-shaped insulator (14), to whose inner bottom surface (18) are fixed heater coils (20). The heater coils have an oval cross-section and are pressed by their narrow sides into surface (18) and fixed. The fixing pressing in takes place during the moulding of the moist insulator (14), made from fibrous material and by means of a male mould receiving the heater coils in slots.
