Description

Üordnung zur Verringerung der Wärmeaufnahme an elektrischen Herden Bei elektrischen Kochherden benötigt man besonders für das erste Ankochen einen verhältnismäßig großen Heizwiderstand, während man für das Weiterkochen und besonders zum Warmhalten mit einer wesentlich geringeren Wärmezufuhr zur Heizplatte auskommen kann. Man ist bisher so vorgegangen, durch Teilung des Widerstandes und Anwendung von Serienparallelschaltung die Wärmeaufnahme auf ein Viertel des Höchstbetrages herabzusetzen. In den meisten Fällen genügt aber ein Fünftel oder ein Sechstel des Höchstbetrages und können hierdurch weitere Ersparnisse erzielt werden. Bei den bisherigen Anordnungen verwendet man relativ dünne Heizwicklungen, die bei der höchsten Wattaufnahme parallel geschaltet sind. Es ist aber für die Herstellung und den Betrieb vorteilhafter, mit einem stärkeren Heizdraht zu arbeiten. Um mit einem einzigen Heizleiter von verhältnismäßig starkem Querschnitt auszukommen, wird gemäß der Erfindung das Herabsetzen der Wärmeaufnahme durch die Vorschaltung eines sogenannten Spartransformators erreicht, der für ein Fünftel bis ein Sechstel der vollen Leistung der Heizeinrichtung bemessen ist, d. h. für die volle Heizleistung wird die Heizwicklung an die volle Netzspannung gelegt, und nach Ablauf der Ankochzeit oder in der Zeit des Warmhaltens wird dann mittels eines einfachen Serienschalters auf den Spartransformator umgeschaltet. Die Größe eines solchen Spartransformators ist bei der geringen Leistung so gering, daß er ohne weiteres in die normalen Küchenherde mit eingebaut werden kann.Ordinance to reduce the heat absorption of electric stoves With electric stoves, you need one especially for the first boil relatively large heating resistance, while one for further cooking and especially keep warm with a significantly lower heat supply to the heating plate can. So far this has been done by dividing the resistance and applying it series parallel connection reduces the heat absorption to a quarter of the maximum amount to belittle. In most cases, however, a fifth or a sixth of that is sufficient This means that further savings can be achieved. Both previous arrangements used relatively thin heating coils, the highest Watt consumption are connected in parallel. But it is for manufacturing and operating more advantageous to work with a thicker heating wire. To be with a single To get along with heating conductors of relatively thick cross-section, according to the invention the reduction of the heat absorption through the upstream connection of a so-called autotransformer that for a fifth to a sixth of the full output of the heating device is dimensioned, d. H. for the full heating output, the heating winding is at the full Mains voltage applied and after the boil-up time has elapsed or during the time the food is kept warm is then switched to the autotransformer using a simple series switch. The size of such an autotransformer is so small with the low power, that it can easily be built into normal kitchen stoves.

Die Schaltungsmöglichkeit ergibt sich aus der Zeichnung. a ist der Heizwiderstand, b der Spartransformator, c der Umschalter. In Stellung i ist der Heizwiderstand an die Netzspannung geschaltet, in Stellung 2 nimmt der Schalter c von dem Spartransformatonb einen entsprechenden Spannungsteil ab, so daß die Wärmeaufnahme in wünschenswerter Weise herabgesetzt wird.The circuit option results from the drawing. a is the heating resistor, b the autotransformer, c the changeover switch. In position i the heating resistor is connected to the mains voltage, in position 2 switch c takes a corresponding voltage part from the autotransformer, so that the heat absorption is reduced in a desirable manner.
