Description

Stufenschalter für Heizgeräte, der zu bestimmter Zeit nach dem Einschalten des höchsten Energieverbrauches diesen selbsttätig ausschaltet Gegenstand der Erfindung ist ein Stufenschalter für Heizgeräte, der zu einer bestimmten Zeit nach dem Einschalten des höchsten Energieverbrauches diesen selbsttätig ausschaltet und auch nur zum Ein- und Ausschalten von Hand verwendet werden kann.Step switch for heating devices, which is activated at a certain time after switching on the highest energy consumption turns it off automatically the subject of the invention is a step switch for heating devices that works at a certain time after switching on of the highest energy consumption switches it off automatically and only for Switching on and off by hand can be used.

Es sind bereits Zeitschalter dieser Art, die mit Uhrwerks-, Relais- oder Quecksilberzeitmessern versehen sind, bekannt. Doch sind diese Einrichtungen zu teuer, unhandlich und empfindlich.There are already time switches of this type with clockwork, relay or mercury timers are known. Yet these facilities are too expensive, unwieldy and sensitive.

Erfindungsgemäß 'wird dieser Nachteil dadurch behoben, daß zum Ein- und Ausschalten des Anheizstromkreises von Hand zwei Kontaktfedern durch zwei Nockenscheiben voneinander unabhängig gesteuert werden, beim Einschalten des Anheizstromkreises nacheinander die eine Köntaktfeder an einem federnden Arm in eine durch eine Nase gesperrte Stellung gelegt und an den Kontaktfedern der Heizstromkreis für einen Bimetallauslöser eingeschaltet wird, und daß dann nach bestimmter Zeit diese Sperrung dadurch gelöst wird, daß das äußere Ende des Bimetalls gegen das äußere Ende des Sperrfederarms drückt und der Anheizstromkreis sowie der Heizstromreis für den Bimetallauslöser hierdurch ausgeschaltet werden.According to the invention 'this disadvantage is eliminated by the fact that and switching off the heating circuit by hand using two contact springs using two cam disks can be controlled independently of each other when the heating circuit is switched on one after the other the one contact spring on a resilient arm into one through a nose locked position and placed on the contact springs of the heating circuit for one Bimetal release is switched on, and that then after a certain time this blocking is achieved in that the outer end of the bimetal against the outer end of the The locking spring arm presses and the heating circuit and the heating circuit for the bimetallic release thereby be switched off.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt, und zwar sollen nacheinander zwei Stromkreise betätigt und der letztere nach bestimmter Zeit abgeschaltet werden.In the drawing, the subject of the invention is for example shown, namely two circuits are operated one after the other and the latter switched off after a certain period of time.

Abb. z zeigt die Zeitschalteinrichtung in Draufsicht im ausgeschalteten Zustand, Abh. a Stromkreis I eingeschaltet, Abb. 3 Stromkreis 1 und II eingeschaltet. Auf der Grundplatte a ist .ein Drehschalter o in bekannter Weise angeordnet. An der Achse b des Schalters sind zwei Nockenscheiben c und d befestigt. Der Nockend beeinüußt den federnden Kontaktarm e. Unter dem Kontaktarm e liegt der federnde Kontaktarm f. Dieser ruht auf der Nase g des federnden Sperrarms A. Gegen das vordere Ende ;1 des Sperrarms lt drückt der durch Wärme leicht verformbare, z. B. aus Bimetall gebildete Stab k. Der 'Metallstab h ist mit einer Heizwicklung nz umgeben. Soll der Stromverbraucher I eingeschaltet werden, so wird von Hand der Schaltkörper o mit dem Nokken d so gestellt, daß der Nocken.rl, wie in Abb. 2 ersichtlich, den Kontaktarme hebt. Die Nockenscheibe c hebt während dieser Drehung den Kontaktarm/ auf die Nase Alsdann fließt der Strom über den Dreh schaltkörper o durch den Widerstand I in Pfeilrichtung r. Wird der Schaltknopf weitergedreht, so gibt der Nockend den Kontaktarm e frei, und die Nase zz des Kontaktarms e drückt dann auf den Kontaktarm f. wodurch der Strom über den Drehschaltkörper o in den beiden Pfeilrichtungen b Ilie ßt (äielie Abb. 3 ) und die Stromverbraucher I und 11 eingeschaltet sind. Außerdem ist auch der Widerstandzn mit dem Stromverbraucher 1I in Reihe geschaltet und dadurch die Zeitschaltvorrichtung in Betrieb gesetzt. Durch die erzeugte Wärme in dem Widerstand in dehnt sich der Stab /z .aus, und das Ende des Stabes .k drückt dann gegen das Endei der Sperrfederh. Hierdurch wird die Nase :;' zurückgedrückt und der Kontaktarm f frei, so daß der Kontakt bei tz unterbrochen wird und der Energieverbraucher II und Widerstandzn ausgeschaltet werden. Der Energieverbi-aiicher 1 bleibt weiterhin eingeschaltet. Soll der Widerstand nz im Nebenschltil:7 lieben, was bei Verwendung gewisser Gebraucbsgeräte erforderlich ist, wird in den Schalter ein Transformator eingebaut. um de#n Widerstand nicht zu hoch zu belasten.Fig. Z shows the time switch device in a top view in the switched-off state, depending on a circuit I switched on, Fig. 3 circuit 1 and II switched on. A rotary switch o is arranged in a known manner on the base plate a. Two cam disks c and d are attached to the axis b of the switch. The cam end influences the resilient contact arm e. The resilient contact arm f lies under the contact arm e. This rests on the nose g of the resilient locking arm A. Against the front end; B. formed from bimetal rod k. The 'metal rod h is surrounded by a heating coil nz. If the power consumer I is to be switched on, the switch body o with the cam d is set by hand so that the Nocken.rl, as can be seen in Fig. 2, lifts the contact arm. During this rotation, the cam disc c lifts the contact arm / onto the nose. The current then flows over the rotary switch body o through the resistor I in the direction of the arrow r. When the operation knob is further rotated, the Nockend are the contact e free, and the nose zz then presses the contact e on the contact f. Whereby the current through the rotary switch body o in the two directions of arrow b Ilie SST (äielie Fig. 3) and the Power consumers I and 11 are switched on. In addition, the resistor is also connected in series with the current consumer 1I and the timer device is thereby put into operation. The generated heat in the resistor in causes the rod / z. To expand and the end of the rod .k then presses against the end of the locking springh. This makes the nose:; ' pushed back and the contact arm f free, so that the contact is interrupted at tz and the energy consumer II and resistance zn are switched off. The energy consumption 1 remains switched on. If the resistance is nz in the secondary circuit: 7, which is necessary when using certain appliances, a transformer is built into the switch. in order not to overload the resistance.
