Description
Steuervorrichtung für ein wechselstrombetriebenes Heizgerät. Control device for an AC powered heater.
Die Erfindung bezient sich auf eine Vorrichtung zum Steuern der Leistung eines Heizwiderstandes in einem wechselstrombetriebenen Keizberät.The invention relates to an apparatus for controlling power of a heating resistor in an AC operated Keizberät.
Aufgabe der Erfindung ist es, eine derartige Vorrichtung zu verbessern, insbesondere das Steuern der in dem Heizwiderstand in Wärme ungesetsten elektrischen Leistung einfacher und wirksamer durchzuführen. Hierbei ist unter einem eizwiderstand sowohl ein einzelner Ohmscher Widerstand als auch eine in geeigneter Weise geschaltete Gruppe derartiger Widerstände zu verstehen.The object of the invention is to improve such a device, in particular the control of the electrical ones that are unset in heat in the heating resistor Easier and more effective performance to perform. Here is under a heating resistance both a single ohmic resistor and one suitably switched To understand group of such resistances.
Bei einer Vorrichtung der eingangs genannten Art besteht die Erfindung darin dass in Reihe mit dem Heizwiderstand ein den Stromdurchgang beeinflussender Bauteil geschaltet ist, und dass parallel zu dem Bauteil ein diesen überbrückender Steuerschalter geschaltet ist, sodass bei geöffnetem Steuerschalter die Beeinflussung des Stromdurchganges durch den Bauteil eintritt und bei geschlossenem Steuerschalter der Bauteil kurzgeschlossen ist.The invention consists in a device of the type mentioned at the beginning in that in series with the heating resistor one influencing the passage of current Component is connected, and that parallel to the component a bridging this Control switch is switched, so that the influence when the control switch is open the passage of current through the component occurs and with the control switch closed the Component is short-circuited.
Eine Ausführungsform der Vorrichtun nach der .Erfindung besteht darin, dass der bauteil eine Diode ist. sodass der Heizwiderstand bei geöffnetem Steuerschalter infolge Unterdrückung einer Halbwelle nur die halbe Leistung und bei geschlossenem Steuerschalter die volle Leistung aufnimmt.An embodiment of the device according to the invention consists in that the component is a diode. so that the heating resistor is open when the control switch is open due to the suppression of a half-wave, only half the power and when the power is closed Control switch takes full power.
Eine weitere Ausführungsform der Vorrichtung nach der Erfindung besteht darin, dass der Bauteil ein Transistor ist, sodass der Heizwiderstand bei geöffnetem Steuerscnalter nur den der kontinuierlich veränderlichen Einstellung des Transistors entsprechenden Teil der Leistung und bei geschlossenem Steuerschalter die volle Leistung aufnimmt.Another embodiment of the device according to the invention consists in that the component is a transistor, so that the heating resistor when open Control switch only that of the continuously variable setting of the transistor corresponding part of the power and the full when the control switch is closed Performance.
Der Unterschied zwischen den beiden Ausführungsformen der'Vorrichtung nach der Erfindung besteht im wesentlichen darin, dass im Falle der Verwendung einer Diode nur eine Halbierung der Wärme leistung des Heizwiderstandes erreicht werden kann, während im Falle der Verwendung eines Transistors die Diärmeleistung des Heizwiderstandes durch entsprechende Beschaltung des Transistors eine kontinuierlich veränderliche Einstellung erfahren kann.The difference between the two embodiments of the device according to the invention consists essentially in the fact that in the case of using a Diode only halving the heat output of the heating resistor can be achieved can, while in the case of the use of a transistor, the thermal power of the heating resistor a continuously variable one through appropriate wiring of the transistor Can experience attitude.
In der Zeichnung ist ein Ausführungsbeispiel der Schaltung einer Vorrichtung nach der Erfindung schematisch dargestellt.In the drawing is an embodiment of the circuit of a device shown schematically according to the invention.
Der Heizwiderstand 1 ist an eine Wechselstromquelle 7 über einen zweipoligem Hauptschalter 6 angeschlossen, mittels dessen das Heizgerät willkürlich abgeschaltet werden kann. In Reihe mit dem Heizwiderstand 1 ist eine Diode 2 und ein Raumthermostat-Schalter 5 üblicher Funktion geschaltet.The heating resistor 1 is connected to an alternating current source 7 via a two-pole Main switch 6 connected, by means of which the heater switched off arbitrarily can be. In series with the heating resistor 1 is one Diode 2 and a room thermostat switch 5 of the usual function switched.
Mittels der Leitung 3 ist in ParallelsenAltung zu der Diode 2 ein Steuerschalter 4 anbeordnet. Bei geöffnetem Steuerschalter 4 ist ein Stromdurchgang von der Wechselstromquelle 7 zu dem Heizwiderstand 1 nur über die Diode 2 möglich. Entsprechend der Funktion der Diode 2 wird hierbei jeweils die eine Halbwelle des TTechselstromes unterdrückt, so-dass der Heizwiderstand 1 nur die halbe elektrische Leistung aufniìmmt. Bei geschlossenem Steuerschalter 4 ist dagegen die Diode 2 kurzgeschlossen, sodass der Heizwiderstand 1 die volle elektrische Leistung über die Leitung 3 und den Steuerschalter 4 aufnehmen kann.By means of the line 3 in parallel with the diode 2 is a Control switch 4 arranged. When the control switch 4 is open, there is continuity of current from the alternating current source 7 to the heating resistor 1 only possible via the diode 2. In accordance with the function of the diode 2, one half-cycle of the T AC suppressed so-that the heating resistor 1 only half the electrical Performance. When the control switch 4 is closed, however, the diode 2 is short-circuited, so that the heating resistor 1 the full electrical power via the line 3 and the control switch 4 can accommodate.
Selbstverständlich sind die Kennwerte der Diode 2 entsprechend den Nennsferten des Heizwiderstandes 1-und der Wechselstromquelle 7 zu wählen.Of course, the characteristics of the diode 2 are in accordance with Nominal values of the heating resistor 1 and the alternating current source 7 to be selected.
