Description
Bei elektrisch beheizten Geweben wurden bisher in unmittelbarer Nähe des Heizwiderstandes ein oder mehrere Thermoschalter angeordnet, die denselben abschalten, wenn durch zu lange Einschaltung oder durch Kurzschluß eine unzulässige Erwärmung entsteht. Bei allen bekannten Anordnungen erfolgte die Ausschaltung in der Nähe der Gewebe, was wegen der hierbei möglichen Lichtbogenbildung unerwünscht ist. Man hat auch die Schalter nach außen verlegt, um diese Gefahr zu beseitigen, und sie indirekt durch eine besondere Heizwicklung· beheizt; hierbei besteht jedoch die Gefahr, daß beim Schadhaftwerden der B eheizungs wicklung der Schalter unwirksam wird und auch bei Überheizung eine Abschaltung nicht erfolgt.In the case of electrically heated fabrics, up to now, the heating resistor was in the immediate vicinity one or more thermal switches arranged to switch off the same when if the device has been switched on for too long or a short circuit, inadmissible heating occurs. In all known arrangements, the elimination took place in the vicinity of the tissue, what is undesirable because of the possible arcing. The switches have also been moved outside to avoid this danger to eliminate, and they are indirectly heated by a special heating coil ·; here exists however, there is a risk that the switch will be damaged if the heating system is damaged becomes ineffective and shutdown does not take place even in the event of overheating.
Die nachstehend beschriebene neue Schaltung ist frei von diesen Nachteilen und unterscheidet sich von den bekannten dadurch, daß sowohl das Einschalten als auch das Ausschalten der Heizwiderstände durch außerhalb des Gewebes liegende Thermostaten erfolgt, daß also eine Lichtbogenbildung in der Nähe des Gewebes unmöglich wird.The new circuit described below is free from these drawbacks and is different differs from the known in that both switching on and switching off the heating resistances are carried out by thermostats located outside the tissue, so that arcing occurs in the vicinity of the tissue becomes impossible.
In beiliegender Zeichnung ist A der Gewebeheizwiderstand, der auch, wie üblich, in zwei Teile geteilt werden kann, die durch den Schalter B in Reihe, einzeln oder nebeneiinander geschaltet werden. C ist ein. hier mit dem Steckkontakt vereinigt angenommenes Gehäuse, welches zwei Thermoschalter I und III, die durch Heizwicklungen 2 und 7 beheizt werden, .enthält. II ist ein dritter im Gewebe angeordneter Thermoschalter. I und II schließen, III öffnet bei Erwärmung den zugehörigen Stromkreis. 6 ist eine Schmelzsicherung. Die Teile arbeiten nun wie folgt zusammen: Beim Einschalten fließt zunächst ein Strom über den Heizwiderstand 2 des Thermoschalters I, schließt diesen und gibt hierdurch dem Gewebeheizwiderstand Strom. Bei Erreichung der Temperaturgrenze arbeitet der Thermoschalter II und schaltet hierdurch den Heizwiderstand 7 des Thermoschalters III ein, durch dessen Wärmewirkung das Ganze abgeschaltet wird. Nach Abkühlung beginnt das Spiel von neuem.In the accompanying drawing, A is the fabric heating resistor, which, as usual, can also be divided into two parts, which are connected in series, individually or next to each other by switch B. C is a. Here with the plug contact combined assumed housing, which contains two thermal switches I and III, which are heated by heating windings 2 and 7. II is a third thermal switch arranged in the tissue. I and II close, III opens the associated circuit when heated. 6 is a fuse. The parts now work together as follows: When switching on, a current first flows through the heating resistor 2 of the thermal switch I, closes it and thereby gives the tissue heating resistor current. When the temperature limit is reached, the thermal switch II works and thereby switches on the heating resistor 7 of the thermal switch III, the thermal effect of which switches the whole thing off. After cooling down, the game starts again.
