Description
Durch das Patent 492 340 ist eine Anordnung zur Verringerung der Wärmeaufnahme der in elektrische Herde eingebauten Heizleiter bekanntgeworden, bei der für die Zeit des Warmhaltens oder Fertigkochens der Speisen die Heizwicklung mittels eines Umschalters auf einen eingebauten Spartransformator umgeschaltet wird, um eine Unterteilung des Heizleiters zu vermeiden und mit einem einzigen Heizleiter von verhältnismäßig starkem Querschnitt auskommen zu können. Bei einer derartigen Anordnung liegt der Spartransformator mit seiner gesamten Wicklung bzw. Primärwicklung stets am Netz!.An arrangement for reducing the heat absorption of the heating conductors built into electric stoves has become known through patent 492 340, in which the heating coil is switched to a built-in autotransformer by means of a changeover switch in order to avoid subdivision of the heating conductor while the food is being kept warm or ready to be cooked and to be able to manage with a single heating conductor with a relatively large cross-section. With such an arrangement, the autotransformer is always connected to the mains with its entire winding or primary winding ! .
Es wird also in der Zeit des Anheizens bei großer Wärmeaufnahme des Heizleiters über den Transformator ein wenn auch kleiner Strom fließen, der einen Verlust darstellt.So it becomes over during the heating-up period when the heat conductor absorbs a great deal of heat A current, albeit a small one, will flow through the transformer, which is a loss.
Die Erfindung beseitigt diese Nachteile durch die Verwendung eines Relais, das im Stromkreis zum Transformator liegt und geschlossen wird, wenn der Umschalter auf Sparstellung steht, dagegen offen ist, wenn der Umschalter auf Anheizen steht. Hiierdurch sind Leerlaufverluste des Transformators vermieden.The invention overcomes these disadvantages through the use of a relay which is im Circuit to the transformer is and is closed when the changeover switch is on Economy position is, on the other hand it is open when the switch is on heating up. Through this no-load losses of the transformer are avoided.
Aus der Zeichnung ist die Schaltungsmöglichkeit zu ersehen, α ist der Heizleiter, b der Spartransformator, c das im Stromkreis zum Spartransformator liegende Relais, dessen Magnetwicklung d in dem Stromkreis zum Umschaltern liegt. In der gezeichneten Stellung des Umschalters e auf den Kontakt 1 liegt der Heizleiter α direkt am Netz. Der Stromkreis des Transformators b ist durch das Relais c unterbrochen. Wird auf den Kontakt 2 umgeschaltet, so wird die Magnetspule d gespeist, der Anker wird angezogen und das Relais c geschlossen, so daß der Transformator eingeschaltet wird.From the drawing, the circuit option can be seen, α is the heating conductor, b is the autotransformer, c is the relay in the circuit to the autotransformer, whose magnet winding d is in the circuit to the switch. In the position shown with the switch e on contact 1, the heating conductor α is directly connected to the network. The circuit of the transformer b is interrupted by the relay c . If the switch is made to contact 2, the magnet coil d is fed, the armature is attracted and the relay c is closed, so that the transformer is switched on.
