Description

Ro w e n t a Metallwarenfabrik GmbH., Offenbach am Main, Waldstraße 232 "H e i z l ü f t e r " Heizlüfter, insbesondere solche kleinerer Bauart, wie sie für den Hausgebrauch vielfach verwendet wer- tief,benutzen als Antriebsmotor für die Luftschrau- be gewöhnlich Spaltpolmotoren. Diese sind einfach herstellbar, haben eine große Lebensdauer und sehr geräuscharm. Ihr Nachteil ist das sehr geringe Anlaufdrehmoment. Insbesondere kann es vorkommen, daß die Motoren, wenn sie längere Zeit nicht in Gebrauch waren, durch Verharzung des Fettes in den Lagern nicht anlaufen.Ro wenta Metallwarenfabrik GmbH., Offenbach am Main, Waldstraße 232 "H eizlü fter" fan heaters, especially those of a smaller design that are often used for domestic use deep, used as a drive motor for the air screw usually shaded pole motors. These are easy manufacturable, have a long service life and very low noise. Their disadvantage is the very low starting torque. In particular, if the motors have not been used for a longer period of time, the grease in the bearings may resinify and not start up.

Die Heizwicklung eines solchen Gerätes ist so dimensioniert, daß sie bei normalem Gebrauch, d.h. also, wenn der Motor ordnungsgemäß läuft, durch den Luftstrom so stark gekühlt wird, daß sie nicht oder kaum zum Glühen kommt. Bei Ausfall des Luftstromes, beispblsweise durch Versagen des Motors, steigt die Tem- peratur des Haizwiderstandes sehr hoch an, so daß der Heizdraht entweder durchbrennen kann oder aber Gefahr für das Gerät selbst besteht.The heating coil of such a device is dimensioned so that during normal use, ie when the engine is running properly, it is so strongly cooled by the air flow that it does not or hardly glow. If the air flow fails, for example due to a failure of the motor, the temperature rises temperature of the shark resistance is very high, so that the The heating wire can either burn through or there is a danger to the device itself.

Der Erfindungszweck wird dadurch erreicht, daß zum Schutz gegen Durchbrennen oder Überhitzen der Heizwicklung zwischen der Luftschraube und dem Heizdraht ein Schalter angeordnet ist, des den Strom für den Heizwiderstand nur bei genügendem starken Luftstrom einschaltet. Zweckmäßig ist der Schalter mit einer Klappe versehen, die im Luftstrom liegt. Der Schalter besteht vorzugsweise aus einem Quecksilberschaltrohr.The purpose of the invention is achieved in that to protect against burning through or overheating of the heating coil between the propeller and the heating wire a Switch is arranged, the current for the heating resistor only when sufficient turns on strong airflow. The switch is expediently provided with a flap, which lies in the air stream. The switch preferably consists of a mercury switching tube.

Anhand der Figur Mi die Wirkungsweise der Erfindung kurz erläutert ! der Motor 1 mit den Anschlußklemmen 2 trägt eine Luftschraube 3. Bei ordnungsgemäßem Lauf erzeugt dieser einen Luftstrom in Pfeilrichtung 4.The mode of operation of the invention is briefly explained with reference to FIG ! the motor 1 with the terminals 2 carries a propeller 3. When it is working properly Run this generates an air flow in the direction of arrow 4.

Vor der Luftschraube 3 im Luftstrom ist der Heizwiderstand 5 angeordnet. Die an diesem vorbeiströmede Luft erwärmt sich. Gleichzeitig kühlt jedoch der Luftstrom den Heizwiderstand 5 ab, so daß dieser nicht unzulässig erwärmt wird.The heating resistor 5 is arranged in front of the propeller 3 in the air stream. The air flowing past this heats up. At the same time, however, the air flow cools the heating resistor 5 from so that it is not excessively heated.

In dem von der Luftschraube 3 erzeugten Luftstrom 4 ist eine um eine Achse 8 drehbare Klappe 9 angeordnet.In the air flow 4 generated by the propeller 3 is one by one Axis 8 rotatable flap 9 is arranged.

Fest mit der Klappe 9 ist eine Haltevorrichtung lo verbunden, die ein Quercksilberschaltrohr 11 trägt. In der Ruhestellung, also bei stillstehendem Motor, befindet sich die Luftklappe 9 mit Quecksilberschaltrohr 11 in der dargestellten Lage, d. h. die beiden Stromzuführangen 12a und 12b zum Quecksilberschaltrohr 11 sind unterbrochen. Setzt sich der Motor in Bewegung, so wird von einer bestimmten Umlaufgeschwindigkeit ab der Luftstrom so stark, daß die Klappe 9 in Pfeilrichtung 4 bewegt wird, bis schließlich das Quecksilberschaltrohr 11 den Strom für den Heizwiderstand einschaltet.Fixed to the flap 9 is a holding device lo is connected a transverse silver switching tube 11 carries. In the rest position, i.e. when the vehicle is at a standstill Motor, the air flap 9 with mercury switching tube 11 is in the illustrated Location, d. H. the two power supply lines 12a and 12b to the mercury switching tube 11 are interrupted. When the motor starts moving, a certain one is used Circulation speed from the air flow so strong that the flap 9 in the direction of the arrow 4 is moved until finally the mercury switching tube 11 supplies the current for the heating resistor turns on.

Anstelle des Quecksilberschaltrohres 11 kann selbstverständlich auch ein anderes geeignetes Kontaktsystem verwendet werden. Das Gebrauchsmuster ist nicht auf die dargestellte sfuhrungsform beschränkt. Vielmehr können Einzel- heiten dem jeweiligen Verwendungezweck angepaßt wer- den ohne vom grundsätzlichen Erfindungsgedanken abzuweichen.Instead of the mercury switching tube 11, another suitable contact system can of course also be used. The utility model is not based on the one shown limited management. Rather, individual units are adapted to the respective purpose of use without deviating from the basic inventive concept.
