Description

  

  Elektrische Kochplatte.    Vorliegende     Erfindung    betrifft eine elek  trische Kochplatte mit Widerstandsheizung,  welch letztere einen Kern aus Isoliermaterial  und darauf aufgewickeltem     Widerstands-          material    aufweist.  



  Gemäss der Erfindung ist an der Unter  s?ite der Kochplatte mindestens eine Nut       vorhanden,    welche zur Aufnahme der elek  trischen Heizvorrichtung dient, die zwecks  guter     Wärmeübertragung    an die     Nutenwand     anliegt.  



  Beiliegende     Zeichnung    zeigt eine beispiels  weise     Ausführungsform    des Erfindungs  gegenstandes.  



  In     hig.    1 ist     rc    die im Schnitt gezeichnete       Kochplatte,    zum Beispiel aus Gusseisen, die  an ihrer Unterseite Rippen b enthält, wo  durch Nuten c gebildet sind. Diese dienen  zur Aufnahme von je zwei. bandförmigen       Widerstandskörpern    e., die hochkant gestellt  sind und, wie in     Fig.    2 besser veranschau  licht ist, aus einem Isolierstreifen f, zum  Beispiel aus Glimmer, bestehen mit darauf       aufgewickeltem        bandförmigem    Widerstands-    material     rg,    das auch aus Draht sein könnte;

    es ist nur der in der einen Nut c vorhandene  Teil der Heizvorrichtung eingezeichnet. -Zu  beiden Seiten des     Widerstandskörpers    e be  findet sich je ein Isolierstreifen h, beispiels  weise     ebenfalls    aus Glimmer, während       zwischen    den beiden inneren Isolier  streifen     la    zwei Schutzstreifen<I>i,</I> beispiels  weise aus     Eisenblech,    vorgesehen sind. Die  beiden Widerstands- oder Heizkörper e wer  den mittelst eines zwischen die beiden  Schutzstreifen i eingeführten, keilförmigen  Metallstuckes     k    an den ihnen je von einer  Rippe b' dargebotenen Wandteil der Nute  angedrückt.

   Dadurch wird die Wärmeüber  tragung vom Heizkörper auf die     Nutenfläche     und mithin auf die Kochplatte eine vorzüg  liche, so dass es möglich wird, die Kochplatte  sehr hoch zu belasten, ohne dass das Wider  standsmaterial vorzeitig zugrunde geht.  



       Di´Kochplatte    könnte eventuell auch nur  eine Nut zur Aufnahme der Heizvorrichtung  besitzen. Diese könnte ihrerseits auch nur aus  einem Heizkörper, statt     aus    mehreren sol-      (Ion, bestehen. Der Heizkörper kann natür  lich auch in anderer Form auftreten, als es  beim gegebenen Beispiel der Fall ist, -wie die  Nut oder die Nuten der Kochplatte ebenfalls  andere Form als gezeichnet besitzen kann       bezW.        können.  



  Electric hotplate. The present invention relates to an electric hotplate with resistance heating, the latter having a core made of insulating material and resistance material wound thereon.



  According to the invention, at least one groove is present on the underside of the hotplate, which groove serves to accommodate the electrical heating device which rests against the groove wall for the purpose of good heat transfer.



  The accompanying drawing shows an example embodiment of the subject invention.



  In hig. 1 rc is the cooking plate drawn in section, for example made of cast iron, which contains ribs b on its underside, where grooves c are formed. These are used to accommodate two each. ribbon-shaped resistance bodies e., which are placed on edge and, as is illustrated better in FIG. 2, consist of an insulating strip f, for example made of mica, with ribbon-shaped resistance material rg wound thereon, which could also be made of wire;

    only the part of the heating device that is present in one groove c is shown. On both sides of the resistor body e there is an insulating strip h, for example also made of mica, while two protective strips are provided between the two inner insulating strips la, for example made of sheet iron. The two resistance or heating elements e are pressed against the wall part of the groove presented to them by a rib b 'by means of a wedge-shaped metal piece k inserted between the two protective strips i.

   As a result, the heat transfer from the radiator to the groove surface and thus to the hotplate is an excellent one, so that it is possible to load the hotplate very heavily without the resistance material perishing prematurely.



       The hotplate could possibly only have one groove to accommodate the heating device. This could in turn consist of just one heating element instead of several sol- (ion. The heating element can of course also appear in a different form than is the case in the given example, such as the groove or the grooves of the hotplate also different Can or can have shape as drawn.
