Definitions

  • the invention relates to a hotplate heating element according to the preamble of claim 1.
  • a known electrical heating device in a known electrical heating device according to US-A-1 636 029, cell-like cavities, delimited by ribs, are provided on the underside of a metallic hotplate body, in which heating elements are arranged.
  • the ribs delimit concentric cavities to accommodate heating elements of different heating capacities.
  • a resistance layer is applied to the underside of a carrier plate, which is repeatedly interrupted by radial and concentric incisions to form, for example, meandering heating conductors, such that the areas of the resistance layer take the form of Have circular or circular ring sectors. It is provided here that annular or circular areas of different electrical surface loads arise.
  • a thin-walled metal body has radial stiffening ribs.
  • a heating foil is applied, which can be designed so that the edge zone performance is preferred.
  • a plate-shaped floor heating element for electrical heating devices is known, which is divided by core-shaped, radial slots into sector-like areas which are connected at the plate edge. These sectors, which are individually resilient to a certain extent, are intended to improve contact with an uneven, heated floor.
  • the invention has for its object to design a hotplate heating element according to the preamble of claim 1 so that the special features of the flat conductor technology are advantageously used for heating hotplates in a structurally and technically simple manner. This object is achieved by the features listed in the characterizing part of claim 1. Advantageous developments of the invention result from the following patent claims.
  • the solution according to the invention results in a hotplate heating element which can be designed in a particularly flat design and which opens up the possibility of obtaining different, selectable heating surface loads on the entire, for example circular heating surface, in particular for the parboiling and continued cooking process (normal cooking process).
  • Such box configurations with different heating capacities can be produced in a particularly advantageous manner using the so-called thick-film paste technique.
  • the cross section of all heating conductor tracks or heating conductor sections is the same, it is also possible within the scope of the invention to vary the heating track cross section in order to achieve different heating effects in this way. In the former case, i.e. with a constant cross-section, one becomes different Achieve heating effects by arranging the distances between the heating conductors, for example meandering, at different distances from one another or by providing different gaps between the meandering sections.
  • the exemplary embodiment according to FIG. 1 is, for example, a circular hotplate heating element which can be used directly or indirectly, for example in connection with a trough plate or glass ceramic plate, as hotplate heating.
  • It has as carrier 1 a flat, smooth steel plate made of a scale-resistant material up to approx. 700 ° C., which is preferably provided on both sides with enamel coatings 2 and 3.
  • This metallic carrier 1 is provided with a protective conductor connection, not shown.
  • a thick-film heating conductor track 4 is applied to the underside of the carrier 1 on the enamel layer 3, for example by baking, in the geometric arrangement explained below.
  • This cover layer 5 for example glass layer, has a relatively high dielectric strength at 1250 V.
  • a fastening bolt 7 is provided which extends through and protrudes through the aforementioned layers and is welded to the carrier 1. This mounting bolt 7 is used for mechanical attachment of the hotplate heating element, for example in a hob of the type mentioned.
  • different heating zones are segment-shaped in the form of circular sections of different surfaces.
  • wide, segment-shaped heating zones 24 and narrow segment-shaped heating zones 25 are alternately strung together within the annular overall heating zone 21 with an unheated central zone 22 and an unheated peripheral zone 23.
  • a single heating conductor 4 can be provided here for all heating zones, or it can be a two-circuit heating with a heating conductor for the wide heating zones 24 and a heating conductor for the narrow heating zones 25.
  • the narrow heating zones 25 form the heating Heating zones and the wide heating zones 24 normal cooking heating zones.
  • connection contact surfaces can be provided for the connection of the heating conductor.
  • the individual heating zones are largely thermally decoupled from one another. 1 by insulating webs 26, which are arranged in the region between the heating zones 9 and 10 and preferably also extend through the carrier 1, so that in this way a clear thermal delimitation of the various heating zones or none significant thermal influence on the adjacent heating zone and, if possible, no heat conduction in the support 1 is obtained.
  • insulating bars 26 instead of insulating bars 26 or additionally, between the heating zones, e.g. in the material of the carrier 1 and / or top layer 5, heat sinks e.g. be provided in the form of material constrictions.
  • the hotplate surface can have a plurality of separate heating conductor tracks 4a or 4b, which are illustrated in FIG. 3 on the basis of a circuit diagram.
  • the same or different heating powers can be assigned to these heating conductor tracks, as indicated in FIG. 3 by different numbers of turns.
  • All heating conductor tracks are parallel to one another and can be connected individually or in combination to the power source via a multi-stage switch 38.
  • a total of nine heating levels, consisting of four individual heating levels and five combination heating levels, each with operation of two heating conductor tracks, are obtained through four heating conductor tracks.
