Description
Elektrisches Raumheizgerät Die vorliegende Erfindung bezieht sich auf ein elektrisches Raumheizgerät mit Lüfter und Übertemperaturauslöser, bei dem der Antriebsmotor für den Lüfter konzentrisch von der Heizwicklung umgeben ist.Electric Space Heater The present invention relates to an electric space heater with fan and excess temperature release, in which the drive motor for the fan is concentrically surrounded by the heating coil.
Es sind derartige Raumheizgeräte bekannt, bei denen als Fühlerorgan für den übertemperaturauslöser in der Nähe der Heizwicklung ein Bimetallstreifen angeordnet ist, der bei Übertemperatur der Heizspiralen, z. B. bei Ausfall des Lüftermotors, ein Abschalten der Heizung bewirkt. Bei einer derartigen Anordnung wird aber lediglich die Temperatur der Heizspiralen, nicht aber die des Lüftermotors überwacht.Such space heaters are known in which as a sensor element a bimetal strip near the heating coil for the excess temperature release is arranged, which at excess temperature of the heating coils, z. B. if the fan motor fails, causes the heating to be switched off. In such an arrangement, however, is only monitors the temperature of the heating coils, but not that of the fan motor.
Die Erfindung besteht nun darin, daß als Temperaturfühlerorgan für den Übertemperaturauslöser ein temperaturabhängiger Widerstandsdraht zwischen Heizwicklung und Antriebsmotor für den Lüfter angeordnet ist, der den Antriebsmotor kreisförmig umgibt und konzentrisch zur Heizwicklung liegt.The invention consists in that as a temperature sensor for the overtemperature release is a temperature-dependent resistance wire between the heating coil and drive motor for the fan is arranged, the drive motor is circular surrounds and is concentric to the heating winding.
Gegenüber den bekannten Raumheizgeräten, bei denen durch das Temperaturfühlerorgan des übertemperaturauslösers lediglich die Temperatur der Heizwicklung überwacht wird, weist der erfindungsgemäße Temperaturfühler für Cibertemperaturauslöser durch seine besondere Anordnung zwischen Heizwicklung und Antriebsmotor den Vorteil auf, daß neben der bisher bekannten Überwachung der Heizwicklung auch eine Überwachung des Motors gegen Überlastung, d. h. Übertemperatur, erfolgt. Der Übertemperaturauslöser kann so eingestellt werden, daß bei auftretender Übertemperatur, ganz gleich ob sie an der Heizwicklung oder am Motor auftritt, eine Abschaltung des gesamten Raumheizgerätes von der Netzspannung erfolgt.Compared to the known space heaters, in which by the temperature sensor element of the overtemperature release only monitors the temperature of the heating coil the temperature sensor according to the invention for Ciber temperature triggers through its special arrangement between heating coil and drive motor has the advantage, that in addition to the previously known monitoring of the heating winding also a monitoring of the motor against overload, d. H. Overtemperature, occurs. The overtemperature release can be set so that in the event of overtemperature, regardless of whether it occurs on the heating coil or on the motor, a shutdown of the entire room heater from the mains voltage.
Es ist zwar an sich bekannt, temperaturabhängige Widerstandsdrähte als Temperaturfühler für einen Übertemperaturauslöser zur Überwachung von Heizspiralen zu verwenden. Die Verwendung dieser temperaturabhängigen Widerstandsdrähte erfolgte aber bisher ebenfalls nur zur Überwachung der Temperatur eines einzigen Heizgerätes.It is known per se, temperature-dependent resistance wires as a temperature sensor for an overtemperature release to monitor heating coils to use. These temperature-dependent resistance wires were used but so far only for monitoring the temperature of a single heater.
Weitere vorteilhafte Einzelheiten der Erfindung sind an Hand der Beschreibung der Zeichnung dargelegt.Further advantageous details of the invention can be found on the basis of the description outlined in the drawing.
Fig. 1 zeigt in schematischer Darstellung ein erfindungsgemäßes Heizgerät, Fig.2 und 3 verschiedene Schaltungen für den Temperaturfühler des übertemperaturauslösers.Fig. 1 shows a schematic representation of a heater according to the invention, Fig. 2 and 3 different circuits for the temperature sensor of the excess temperature release.
In Fig. 1 ist mit 1 das Gehäuse des Raumheizgerätes bezeichnet, in dem innerhalb eines Tragringes 2, der am Gehäuse 1 aufgehängt ist, auf radial nach außen verlaufenden Stegen 3 die Heizwicklung 4 angeordnet ist.In Fig. 1, 1 designates the housing of the space heater, in within a support ring 2, which is suspended on the housing 1, on radially externally extending webs 3, the heating coil 4 is arranged.
Die Heizwicklung 4 umschließt den in ihrem Mittelpunkt innerhalb eines Tragringes 5 angeordneten Lüftermotor 6, der mit einem Lüfterflügel 7 versehen ist.The heating winding 4 encloses the fan motor 6 which is arranged in its center within a support ring 5 and which is provided with a fan blade 7.
Erfindungsgemäß ist auf den Stegen 3 den Motor 6 ebenfalls kreisförmig umschließend und konzentrisch zur Heizwicklung 4 liegend als Temperaturfühler für den übertemperaturauslöser ein temperaturabhängiger Widerstandsdraht 8 angeordnet, der mit der Heizung parallel geschaltet ist und mit den Kontakten einer Schalteinrichtung 9 in Reihe liegt.According to the invention, the motor 6 is also circular on the webs 3 surrounding and concentric to the heating coil 4 lying as a temperature sensor for the overtemperature release a temperature-dependent resistance wire 8 is arranged, which is connected in parallel with the heater and with the contacts of a switching device 9 is in series.
In Fig. 2 ist ein Ausführungsbeispiel der Schalteinrichtung 9 dargestellt. Der temperaturabhängige Widerstand 8 ist mit einer Regeleinrichtung 10 und der Heizwicklung 11 eines die Kontakte 12 eines Schalters betätigenden Bimetallstreifens in Reihe geschaltet und liegt parallel zur Heizwicklung des Raumheizgerätes.In Fig. 2, an embodiment of the switching device 9 is shown. The temperature-dependent resistor 8 is connected to a control device 10 and the heating coil 11 of a bimetal strip actuating the contacts 12 of a switch in series switched and is parallel to the heating coil of the space heater.
Erhöht sich die Temperatur der Heizwicklung des Raumheizgerätes über das zulässige Maß hinaus, so wird der temperaturabhängige Widerstand kleiner, und durch die Heizwicklung des Bimetallstreifens fließt mehr Strom. Dadurch wird der Bimetallstreifen ausgebogen und die im Stromkreis der Heizwicklung des Raumheizgerätes liegenden Kontakte 12 geöffnet und die Heizwicklung abgeschaltet.If the temperature of the heating coil of the space heater increases beyond the permissible level, the temperature-dependent resistance becomes smaller and more current flows through the heating coil of the bimetallic strip. As a result, the bimetallic strip is bent and the contacts 12 in the circuit of the heating coil of the space heater are opened and the heating coil is switched off.
In Fig.3 ist eine weitere Ausführungsform der Schalteinrichtung 9 dargestellt. An Stelle des in Fig.2 verwendeten Bimetallstreifens ist mit dem temperaturabhängigen Widerstand 8 eine Spule 13 in Reihe geschaltet, durch die ein öffnen der Kontakte des Heizstromkreises bewirkt wird.A further embodiment of the switching device 9 is shown in FIG shown. Instead of the bimetal strip used in Fig. 2, the temperature-dependent one is used Resistor 8 a coil 13 connected in series, through which an opening of the contacts the heating circuit is effected.
Es ist ohne weiteres möglich, sowohl einen positiven als auch einen negativen temperaturabhängigen Widerstand zu verwenden. Weiterhin kann in dem Stromkreis des temperaturabhängigen Widerstandes ein Magnetverstärker eingeschaltet werden.It is easily possible, both a positive and a to use negative temperature-dependent resistance. Farther can be a magnetic amplifier in the circuit of the temperature-dependent resistor be switched on.
