Abstract (en)
[origin: ES8502306A1] A radiant heating element for heating a glass ceramic plate carries on a circular insulating support heating elements in the form of wire coils fixed thereto, which are arranged in the form of two parallel spiral paths. Two separately switchable heating conductors are successively arranged in one spiral path, while the third heating conductor is positioned alone in the other spiral path. The heating conductors have different power levels and can be switched to different power stages by a seven-timing switch.
