Description

Elektrisch betriebenes Gebläse für kalte und warme Luft Die bisher bekannten Haartrockenanlagen werden durch mechanische, zum Teil zwangsläufige Schaltungen betätigt. Hierbei ist stets die Gefahr vorhanden, daß, falls der Motor während des Betriebes durch irgende$ne Stromunterbrechung versagt, die in einem besonderen Stromkreis angeordneten Hei'x= widerstände durchbrennen. Dieser Übelstand wird durch die Erfindung dadurch beseitigt, daß der selbsttätige Schalter als ein unter dem Einfluß der Strömung der geförderten Luft stehender Kipphebelschalter ausgebildet ist, der die Heizspulenkontakte schließt. Ist kein Luftstrom vorhanden, so befindet sich der Schalter infolge seines Eigengewichts in Ausschaltstellung. Auch fällt der Schalter bei plötzlicher Unterbrechung -des Luftstromes durch Schließen des Lufthahnes oder Stauung des Luftstromes durch Zuhalten der Ausströmöffnungen in seine Ruhelage zurück und schaltet die Heizkörper aus.Electrically operated blower for cold and warm air The previously known hair drying systems are made by mechanical, partly inevitable circuits actuated. There is always the risk that if the engine is running during the Operation has failed due to any power interruption in a special circuit Burn through the arranged Hei'x = resistors. This drawback is made possible by the invention thereby eliminating that the automatic switch as one under the influence of the flow the conveyed air standing toggle switch is formed, which contacts the heating coil closes. If there is no air flow, the switch is due to it Dead weight in switch-off position. The switch also drops in the event of a sudden interruption -the air flow by closing the air valve or blocking the air flow Keep the outflow openings closed in its rest position and switch the radiator on the end.

Soll bei in Betrieb befindlicher Anlage, d. h. bei vorhandenem Luftstrom und eingeschalteten Heizkörpern, kalte Luft entnommen werden, so kann der Kipphebelschalter mittels eines mit einer Handhabe verseh-enlen Sperrglieds in der Offenstellung der Stromschlußkontakte festgehalten werden.Should the system be in operation, i. H. when there is airflow and switched on radiators, cold air can be removed, so the toggle switch by means of a locking element provided with a handle in the open position of the Current connection contacts are held.

Eine Ausführungsform des Erfindungs, gegenstandes ist in der Zeichnung in Abb. i in Seitenansicht mit abgenommenem Abschlußdeckel dargestellt, während Abb. z eine um 9o° gedrehte Seitenansicht zeigt. Es bezeichnet a das an dem elektrischen Ventilator angeschlossene Rohr mit der Drossel- bzi"#. Abstellklappe b, welche mittels des Griffes c drehbar ist. Der bei geöffneter Drosselklappe b das Rohr a durchstreichende Luftstrom stößt im Schaltergehäused infolge Lenkung durch die Führungsplatte e auf die Platte t des Kipphebelschalters g, welcher um den Zapfen lt drehbar ist. Die eine Klemme i desselben ist mit der Stromzuführungsklemmek und die andere Klemme L mit dem Heizspulenkontakt m verbunden, deren anderer Kontakt n mit einer über oder hinter der Klemme h angeordneten weiteren Stromanschlußklemme verbunden ist.An embodiment of the invention, subject is shown in the drawing in Fig. I in a side view with the cover removed, while Fig. Z shows a side view rotated by 90 °. A designates the pipe connected to the electric fan with the throttle valve b, which can be rotated by means of the handle c. The air flow that passes through pipe a when the throttle valve b is open hits the switch housing as a result of being steered by the guide plate e Plate t of the toggle switch g, which is rotatable about the pin lt . One terminal i of the same is connected to the power supply terminal and the other terminal L to the heating coil contact m, the other contact n of which is connected to a further power connection terminal arranged above or behind the terminal h is.

Die Klemmen i und L sind nur in der waagerechten Stellung des Kipphebels ä stromleitend verbunden, also nicht in der punktiert angedeuteten Stellung derPlattef.Terminals i and L are only in the horizontal position of the rocker arm ä connected electrically, so not in the position of the plate indicated by dotted lines.

In dieser Stellung wird die Platte f mit dem Kipphebelschalter g durch Niederdrehen des Griffes o mit dem Sperrglied p gehalten, welcher sich dann in der Weise gegen nie Plattet legt, daß diese sich auch bei stärkstein: Luftstrom nicht anheben kann. In. dieser Stellung wird kalte Luft durch das' auf den Rohrstutzen g aufgesteckte Luftleitungsrohr geleitet.In this position, the plate f with the toggle switch g through Turning down the handle o held with the locking member p, which is then in the Way against never flat, so that this is not even with a strong stone: air flow can lift. In. In this position, cold air is drawn through the 'on the pipe socket g attached air duct.

Der Kipphebelschalterg kann mit Quecksilberkontaktgebung oder in sonstiger Weise wirken.The toggle switch can with mercury contact or in other Act wisely.
