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 :
der Plattenmitte. In, ein facher Weise kann dies dadurch erreicht wer-

der Peripherie hin abnimmt, so dass also von der Mitte weg gegen den Rand pro Längenein- heit :d4r Heizspirale mehr Windungen, ent fallen. Damit wird erreicht, :dass sich die Plattenoberfläche bei allen Sühaltstufennicht deformiert, was sich .auf die Kochtopfböden günstig auswirkt.
In der Zeichnung ist, eine beispielsweise Ausführungsform :des Erfindungsgegenstan- desdargestellt, und zwar zeigt die Wohnung eine Kochplatte in schematischer Weise in Draufsicht.

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:
