ELECTRIC HEATING ELEMENT Russian patent published in 1994 - IPC

FIELD: heating of surface of stove plates, irons, rooms, manufacturing heating of extra clean elements, material drying and other domestic purposes. SUBSTANCE: device uses a dielectric heat-proof base that is transparent to light and infra-red rays; heat-carrying tracks of high-resistance metal deposited by spraying in decorative manner of the base, then ceramics coating is applied, over which temperature control tracks are applied, glaze is laid and a mirror screen is deposited by spraying, from the outside it is coated with heat-insulating material. Ceramics may be deposited in the form of a cone with its vertex being in the center of the heater plane, the control tracks may be coated with metal on ceramics, whose conduction depends on the degree of heating. EFFECT: enhanced effectiveness. 1 dwg
