Definitions

  • the invention relates to an electric hotplate for a stove or the like.
  • a glass ceramic plate which is arranged at a free distance above at least one electrical heating element which consists of a helically wound heating resistor which is mounted in a spiral arrangement in an insulating body, the glass ceramic plate on rests on the edge of the pot-like insulating body.
  • a known hotplate of this type (DE-OS 2 500 586) has an insulating material carrier which supports the glass ceramic plate with raised edges, in the bottom of which grooves are formed between the projecting edges, which run essentially in a spiral and are designed to accommodate a helically wound heating resistor, whereby the heating resistor is sunk in the grooves.
  • the grooves can be a rectangular or semicircular Bo have the shape and the heating resistor is cemented along the entire length or in sections.
  • the disadvantage here is the large amount of heat given off by the heating resistor to the insulating material carrier surrounding it.
  • an electric hot plate is known (DE-AS 2 339 768), in which a heating coil which is laid helically from the center to the outside is held by means of clamps on the flat inner surface of a plate-like structure with the interposition of a layer of thermal insulation material.
  • This holder of the heating coil is very expensive to manufacture.
  • the mechanical hold of the heating coil in the insulating body is only slight, since the wire clips used sit only in the relatively soft insulating material due to frictional engagement.
  • the invention has for its object to keep the heat output of the heating element to the glass ceramic plate by radiation as large as possible and to keep the heat output of the heating element to the holder or the insulating body as small as possible, the attachment of the heating coil should be possible without additional aids.
  • This object is achieved on the basis of an electric hotplate of the type mentioned in that the heating resistor is jammed between rows of pins or the like of the insulating body.
  • the heating coil forming the electrical heating resistor is only in sections and in linear or only point contact with the rows of pins of the insulating body, the heat emission to the insulating body is very low and at the same time the radiation to the glass ceramic plate particularly intense. Clamping the heating coil between the rows of pins results in simple assembly without additional fasteners.
  • the electric hotplate essentially consists of a plate-shaped or pot-shaped insulating body 2, on the bottom of which a heating resistor 5 is arranged, while the rim of the plate supports a glass ceramic plate (not shown).
  • a heating resistor 5 is arranged in the manner of rows of pins.
  • cylindrical cams 3 are arranged on both sides in the manner of rows of pins. The distance 4 of these rows of pins perpendicular to the imaginary screw line is chosen so that a slightly smaller clear width is created than the diameter of the heating coil 5.
  • the heating coil is inserted between the cylindrical cams or the like in accordance with the course of the imaginary screw line or spiral.
  • the heating resistor is held in the insulating body 2 by the pressure which the heating coil receives between the cams 3.
  • the height h of the cams or pins 3 corresponds to at least half the diameter of the heating resistor 5.
