    摘要: An electrical heating element (18) for heating a plate, e.g. a glass ceramic plate (14) has a multilayer insulating support (12) in whose dish-shaped depression heater coils (18) are arranged in spiral form. The heater coils are located on the insulating support surface (17) and have downwardly directed deformations (19) comprising a turn pressed out in the downwards direction. These deformations (19) are embedded in the surface layer (16) of the insulating support, which is mechanically stronger and more thermally conductive than the underlying insulating layer (15). The deformations are produced in a mould (22, 23) carrying the heater coils in slots (21) and by means of a bladelike punch (24) a turn is pressed into a depression (25). The connection between heater coil (18) and insulating support (12) during the moulding thereof comprises a loose insulating material, the heater coil and deformations being placed in slots (27) of mould part (26).

    摘要: A control device for an electrical heating device for a cooking field with a cooking field plate comprises an electro-mechanical switching device for adjusting a power of said heating device with different power levels and comprises two different heating element. The switching device is configured so that starting from a zero-position and rotating in a first rotation direction, a power level for a first heating element is adjusted in a cooking-mode. Rotation in the other direction activates a second heating element in a warm-keeping mode with significantly lower power. A relay is closed by a thermomechanical temperature sensing device below a defined switching temperature of 60° C. to 100° C. and opened above the switching temperature. When closed, the relay connects the two heating elements to an operating voltage for common operation. When opened, the first heating element is switched off for exclusive operation of the second heating element.

    摘要: Heating resistors and/or series resistors (10) are curved in flat corrugation manner from flat band and are so pressed into the bottom (7) of an insulation (3), that they are only prevented by friction from rising from the bottom (7). The resistor (10) has non-offset, uninterrupted, through-edge faces (14, 15). Thus, in the case of a very simple construction, a surface-specific, high power density can be obtained.

    摘要: 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.

    摘要: For producing a radiant heater it is proposed to produce a flat disk-shaped tablet as a separate thermally insulating molding outside of the carrier dish of the radiant heater. On this, heating conductors in the form of corrugated strips provided with fastening feet are pressed into the flat top surface of the tablet. In conclusion the radiant heater is fitted by insertion of this prefabricated component.
