Description
Schaltungsanordnung bei elektrischen Motoren, die in Verbindung mit einer Heizeinrichtung arbeiten. Gegenstand der vorliegenden Erfindung ist eine Schaltungsanordnung bei elektrischen -Motoren, die in Verbindung mit einer elek trischen Heizeinrichtung arbeiten. Bei dieser -#.iiordnurig ist der Motor mit. wenigstens einem Teil des Heizwiderstandes in Serie geschaltet. Dies ermöglicht, ohne Vorschalten eines besonderen Widerstandes einen für nie drige Spannung gewickelten und daher billigen Motor zu verwenden; die Anordnung wird namentlich in Verbindung mit Kleinmotoren zweckmässig sein.
Auf der beiliegenden Zeichnung sind meh rere Ausführungsbeispiele des Erfindungs gegenstandes schematisch veranschaulicht.
Bei der in Fig. 1 dargestellten Ausfüh rungsform ist der Motor a zum vollen Heiz- widerstande b in Serie geschaltet. Der Motor kann zum Beispiel ein Kleinmotor zum Be trieb eines Ventilators sein, der dazu dient, die Luft einer durch den Heizkörper b gebil deten Raumheizung in Zirkulation zu setzen. Es wird bei dieser Anordnung gleichzeitig verhindert, die Heizung in Betrieb zu setzen, ohne auch die Luftbewegungseinriehtung zu betätigen.
Bei dem Beispiel gemäss Fig. ? ist der Heizwiderstand durch die beiden parallel geschalteten Zweire bi und b\ gebildet, wo bei der Motor nur finit dem Zwei#Ze b@ des Widerstandes in Serie geschaltet ist. Die Einrichtung kann so getroffen sein. dass der Zweig b-' finit dein Motor für sich allein ein geschaltet beerden kann.
Bei der Ausführung nach Fi-. .'', sind die beiden -'#\'iderstandszweig-e b1 und b\ und der dazwisehengescbaltete Motor miteinander in Serie geschaltet, wobei der Motor finit einem Teil des Widerstandszwei-es b1 durch eine abschaltbare Verbinduu, c a,us@@eschaltet wer den kann.
Bei dein Beispiel Fig. '1- ist der Motor a als Shunt zu einem Teil des Heizwiderstandes b eingeschaltet. b k:inil zum Beispiel die Heizwiclklun#,- der die Kaffeebohnen auf nehmenden Rösttrommel einer 1iaffeeröst- inasclline sein, welche Trommel durch den Motor a in Umdrehung versetzt wird:
letz- terer kann dabei ein kleiner Spielzeugmotor sein. da die Spannung beliebig niedrig ge- halt(=n erden kann.
Circuit arrangement in electric motors that work in conjunction with a heating device. The present invention relates to a circuit arrangement in electric motors that work in conjunction with an electric heating device. With this - #. Iiordnurig the engine is with. at least part of the heating resistor connected in series. This makes it possible to use a motor wound for low voltage and therefore cheap without connecting a special resistor upstream; the arrangement will be appropriate especially in connection with small engines.
In the accompanying drawings, several embodiments of the subject invention are illustrated schematically.
In the embodiment shown in FIG. 1, the motor a is connected in series with the full heating resistor b. The motor can, for example, be a small motor to operate a fan which is used to circulate the air of a room heating system formed by the radiator b. With this arrangement, it is prevented at the same time to put the heater into operation without also activating the air movement device.
In the example according to FIG. the heating resistor is formed by the two parallel-connected Zweire bi and b \, where in the motor only the two # Ze b @ of the resistor is connected in series. The arrangement can be made like this. that branch b- 'can finitely connect your motor to itself.
When executing according to Fi-. . '', the two - '# \' resistor branches b1 and b \ and the motor connected in series are connected to one another, with the motor finite part of the resistor branch b1 by a disconnectable connection, ca, us @@ eschwitches can be.
In your example Fig. 1- the motor a is switched on as a shunt to part of the heating resistor b. b k: inil for example be the Heizwiclklun #, - the roasting drum of a 1iaffeeröst- inasclline that receives the coffee beans, which drum is set in rotation by the motor a:
the latter can be a small toy motor. since the voltage can be kept as low as desired (= n can be grounded.
