Abstract (en)
[origin: EP0866641A2] An electrical cooker plate has a plate body with a flat surface and heating layer below it. The heating layer is designed as a flat, especially sandwich-type, layer made of heat-resistant material with an electrical resistance element located inside, in contact with the underside of the part of the plate body to be heated. The heating layer is applied to the underside of the plate body and is maintained by a glue or filling material as a support element. The plate body is a glass ceramic plate, on whose underside a metal foil (3) is brought into direct contact, working as heating layer, and which is connected to an electric energy source.
