PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine elektrische Heizvorrichtung, welche in bekannter Weise in einem Gehäuse einen Elektromotor, ein von diesem betriebenes Gebläse und einen elektrischen Heizkörper enthält, und unterscheidet sich von den bisher bekannt gewordenen Vorrichtungen dieser Art dadurch, daß die gesamte angesaugte Luft zunächst den Motor und dessen VorschaltwiderständeThe present invention relates to an electric heating device, which is known in Way in a housing an electric motor, a fan operated by this and a contains electric radiators and differs from those previously known Devices of this type in that all the air sucked in first of all the motor and its series resistors
ίο kühlt und dann, so vorgewärmt, zu den in der Austrittsöffnung des Ventilators befindlichen Heizwiderständen gelangt, um von hier, genügend erhitzt, durch die mit einem nach unten gerichteten Leitgatter versehene Austrittsöffnung nach außen zu entweichen.ίο cools and then, preheated in this way, to the in the outlet opening of the fan is located in the heating resistors, in order from here, sufficiently heated through the outlet opening provided with a downwardly directed guide gate to escape to the outside.
Die Vorrichtung ist auf der beiliegenden Zeichnung beispielsweise "dargestellt, und zwar in Fig. ι in Ansicht und teilweise im Längsschnitt und in Fig. 2 zum Teil in Ansicht und Schnitt nach A-B der Fig. 1.The device is shown, for example, in the accompanying drawing, namely in FIG. 1 in view and partly in longitudinal section and in FIG. 2 partly in view and section according to AB of FIG.
α ist der Elektromotor, auf dessen verlängerter Welle b ein Flügelrad c sitzt. Beide Teile bewegen sich innerhalb des Gehäuses df. Die Flügel c werden zweckmäßig etwas nach rückwärts gekrümmt. Das Gehäuse df ist unmittelbar vor dem Motor α mit Durchs bohrungen g versehen, durch welche Luft zum Anker gelangen kann. In dem Ausblaserohr h sind Rahmen i angeordnet, über welche Drähte j von hohem Widerstand ausgespannt sind, die von einem elektrischen Strom durchflossen und hierdurch zum Glühen gebracht werden. Diese Rahmen i sind zweckmäßig" so angeordnet, daß von zwei aufeinander folgenden die Drähte rechtwinklig zueinander stehen. α is the electric motor, on whose extended shaft b an impeller c sits. Both parts move inside the housing df. The wings c are appropriately curved somewhat backwards. The housing df is provided directly in front of the motor α with holes g through which air can reach the armature. In the exhaust pipe h , frames i are arranged, over which wires j of high resistance are stretched, through which an electric current flows and which is caused to glow. These frames i are expediently arranged in such a way that the wires of two successive ones are at right angles to one another.
Wenn, namentlich bei größeren Vorrichtungen der beschriebenen Art, es unmöglich ist, das ganze vom Exhaustor bewegte Luftquantum durch den Motor einströmen zu lassen, versieht man am besten die gegenüberliegende Seitenwand des Gehäuses mit weiteren Durchlaßöffnungen k. Man kann bei diesen Öffnungen die etwa für den Motor erforderlichen Vorschaltwiderstände, diezweckmäßig aus über Rahmen gespannten Drähten oder Bändern bestehen können, anbringen, so daß die durch diese Öffnungen einströmende Luft schon vorgewärmt in den Exhaustor tritt, um dann über die durch den elektrischen Strom zum Glühen gebrachten Drähte j durch das Leitgatter η hindurch in den zu beheizenden Raum geblasen zu werden.If, especially in the case of larger devices of the type described, it is impossible to allow the entire quantity of air moved by the exhaustor to flow in through the motor, it is best to provide the opposite side wall of the housing with further passage openings k. You can attach the necessary ballast resistors for the engine to these openings, which can expediently consist of wires or bands stretched over frames, so that the air flowing in through these openings enters the exhaustor already preheated, in order to then pass through the electric current to the Annealed wires j to be blown through the guide gate η into the room to be heated.
Das Gehäuse kann beliebig gestaltet sein und beispielsweise auch die Form eines Ofens haben.The housing can be designed in any way, including, for example, the shape of an oven to have.
Bei dem Erfindungsgegenstand können auch die Widerstände des Motors vor den Säugöffnungen aufgestellt sein, so daß bei steter Lüftung und Kühlung des letzteren die in ihm frei werdende Wärme, sowie auch die Wärme der eingeschalteten Widerstände zur Vorwärmung der angesaugten Frischluft nutzbringend verwertet wird.In the subject matter of the invention, the resistances of the motor in front of the suction openings be set up so that with constant ventilation and cooling of the latter, the heat released in it, as well as the Heat from the switched-on resistors is useful for preheating the fresh air drawn in is recycled.
Zweckmäßig wird man den austretenden Heißluftstrom gegen den Boden des zu beheizenden Raumes leiten. Das geschieht, indem man das Rohr h nach abwärts richtet, am besten jedoch, indem man die Mündung desselben durch schräg nach abwärts geneigte jalousieartig angeordnete Brettchen bezw. durch das Leitgatter η verschließt, welchesAppropriately, you will guide the exiting hot air stream against the floor of the room to be heated. This is done by directing the tube h downwards, but best by opening the mouth of the same through slabs or slabs that are inclined downwardly in the manner of blinds. by the guide gate η closes, which
den Luftstrom teilt und nach abwärts lenkt. Das Gatter verhindert gleichzeitig, daß durch Berühren der Heizdrähte oder durch eindringende Fremdkörper Kurzschluß verursacht werden kann.divides the airflow and directs it downwards. The gate prevents at the same time that by touching the heating wires or by penetrating Foreign body short-circuit can be caused.
