Description

  

  Elektrische Kochplatte.    Es     ist        bereits    vorgeschlagen worden,     elek-          trisahe    Kochplatten derart     auszubilden,        dass          eine        Plattendeformation    zufolge     vermehrter     Abkühlung am Rand     vermieden    werden  kann.

   Die bekannten Ausführungen sehen  zwei     getrennte        Heizwicklungen    vor, wovon  die     schwächere    zum     Beispiel    im     mittleren          Drittel    des     Kochplattenradius    angeordnet ist.

         Diese    Anordnung kann jedoch ein     Deformie-          ren    der Plattenoberfläche nicht in allen Reiz  stufen verhindern, was auf das     G.eradeblei-          ben    der     Kochtopfböden        eine        ungünstige        Aus-          wirkung    hat.     Die        erfindungsgemässe    Koch  platte     ist        nun        :

  derax-t        konstruiert,    dass jede       Heizwicklung    für     sich    so     ausgebildet        ist,    dass  die Wärmeabgabe gegen den     Plattenrand    hin       grösser    ist als     in    :

  Electric hotplate. It has already been proposed to design electric hot plates in such a way that plate deformation due to increased cooling at the edge can be avoided.

   The known designs provide for two separate heating coils, of which the weaker one is arranged, for example, in the middle third of the hotplate radius.

         However, this arrangement cannot prevent deformation of the plate surface in all stimulus levels, which has an unfavorable effect on the saucepan base remaining straight. The hotplate according to the invention is now:

  derax-t designed that each heating coil is designed in such a way that the heat dissipation towards the edge of the plate is greater than in:

  the center of the plate. In a simple way this can be achieved

  decreases towards the periphery, so that from the center towards the edge per unit of length: the heating coil more turns are omitted. This ensures that: the plate surface does not deform at all levels, which has a favorable effect on the bottom of the saucepan.



  The drawing shows an exemplary embodiment of the subject matter of the invention, namely the apartment shows a hotplate in a schematic plan view.

   For each of the heating wire windings I and II, only one turn of the heating coils is drawn in, in order to design the drawing properly. There. is the pitch S, -C:
