ABSTRACT:
An electrical heating device for cookers and hot plates is disclosed, having a heat-resistant support member disposed below a heat-radiation transmitting plate, in particular, a glass-ceramic plate. The support member is adapted to receive at least one electric heater filament, wherein the support member is disposed within a hollow space between the heat-radiation transmitting plate and a heat-insulating layer or body. The support member is provided with holes or cut-out portions enforcing convection of the air enclosed within the hollow space, and furthermore, the heat-insulating layer being covered by a reflecting sheet or foil, so that a substantial portion of the heat radiated downwards by the heater filament is directed partially by reflection at the sheet or foil and partially by the air current passing over the sheet or foil onto the heat-radiation transmitting plate and onto a cooking or frying vessel standing thereupon.
