Description

GEBIET DER ERFINDUNGFIELD OF THE INVENTION

Die vorliegende Erfindung betrifft eine Motoranordnung für ein elektromotorisch angetriebenes Haushaltsgerät, insbesondere für einen Staubsauger.The present invention relates to a motor assembly for an electric motor driven household appliance, in particular for a vacuum cleaner.

TECHNISCHER HINTERGRUNDTECHNICAL BACKGROUND

Obwohl auf beliebige Haushaltsgerät anwendbar, die elektromotorisch angetrieben werden, wird die vorliegende Erfindung sowie die ihr zugrunde liegende Problematik nachfolgend mit Bezug auf ein als Staubsauger ausgebildetes Haushaltsgerät beschrieben, ohne jedoch die Erfindung aber dahingehend einzuschränken.Although applicable to any home appliance that is driven by an electric motor, the present invention and the problem underlying it is described below with reference to a trained as a vacuum cleaner household appliance, but without limiting the invention to the effect.

Staubsauger weisen typischerweise einen elektrischen Gebläsemotor auf, der zumeist im Inneren des Staubsaugergehäuses angeordnet ist und der die Saugleistung des Staubsaugers bereit stellt. Insbesondere aus Komfortgründen und zur Vermeidung einer unnötigen Lärmbelästigung für die Umgebung besteht bei Staubsaugern stets der Bedarf darin, die während des Betriebs des Staubsaugers insbesondere durch den Gebläsemotor verursachte Geräuschentwicklung, die mitunter als sehr unangenehm empfunden wird, auf ein Mindestmaß zu reduzieren.Vacuum cleaners typically have an electric fan motor, which is usually located inside the vacuum cleaner housing and provides the suction power of the vacuum cleaner. In particular, for reasons of comfort and to avoid unnecessary noise pollution for the environment is in vacuum cleaners always the need to reduce the noise caused during operation of the vacuum cleaner in particular by the blower motor noise, which is sometimes perceived as very unpleasant, to a minimum.

Um die Geräuschemissionen eines Staubsaugers zu reduzieren, existieren verschiedene Lösungsansätze. Beispielsweise kann vorgesehen sein, den Motor mit einer Vielzahl von Geräusch dämpfenden Materialien zu umgeben, welche die vom Motor erzeugten Schallwellen absorbieren und damit die Geräuschemissionen reduzieren sollen. Zusätzlich oder alternativ werden auch möglichst geräuscharme Motoren in die Staubsauger verbaut, welche bereits im Vorfeld die Geräuschentwicklung minimieren sollen.In order to reduce the noise emissions of a vacuum cleaner, various approaches exist. For example, it may be provided to surround the engine with a variety of noise attenuating materials, which absorb the sound waves generated by the engine and thus reduce the noise emissions. Additionally or alternatively, the quietest possible engines are installed in the vacuum cleaner, which should minimize the noise in advance.

Die US 2006/ 0 260 091 A1 offenbart eine Motoranordnung für ein elektromotorisch angetriebenes Haushaltsgerät, insbesondere für einen Staubsauger, mit einem Gehäuse, mit einer Motorkapsel, mit einem Gebläsemotor, der im montierten Zustand im Inneren des Gehäuses und der Motorkapsel angeordnet ist und von diesen umgeben ist, mit einem Dämpfungselement, welches konturgebunden zwischen dem Gehäuse und dem Gebläsemotor angeordnet ist und welches dazu ausgelegt ist und angeordnet ist, vom Gebläsemotor auf das Gehäuse übertragene Schwingungen zu dämpfen, mit einer Fixiereinrichtung, welche das Dämpfungselement, den Gebläsemotor und die Motorkapsel bezüglich des Gehäuses derart fixiert, dass das Dämpfungselement vorgespannt ist.The US 2006/026091 A1 discloses a motor assembly for an electric motor driven household appliance, in particular for a vacuum cleaner, with a housing, with a motor capsule, with a blower motor, which is arranged in the mounted state inside the housing and the motor capsule and surrounded by these, with a damping element, which is arranged contour-bound between the housing and the blower motor and which is designed and arranged to dampen vibrations transmitted from the blower motor to the housing, with a fixing device which fixes the damping element, the blower motor and the motor capsule with respect to the housing such that the damping element is biased.

Auch die US 5 293 664 A offenbart eine derartige Motoranordnung.Also the US 5 293 664 A discloses such a motor assembly.

Die deutsche Patentanmeldung DE 41 00 858 A1 beschreibt einen Staubsauger mit einem Gebläseaggregat, das von einer inneren Gehäusekapsel umgeben ist, die ihrerseits unter Belassung eines Strömungsraumes in eine äußere Gehäusekapsel eingebaut ist, zwischen der und dem Gehäuse des Staubsaugers ein Freiraum besteht, bei welchem Staubsauger ferner der vom Gebläseaggregat erzeugte Luftstrom durch den Strömungsraum zu einem am Staubsaugergehäuse vorgesehenen Auslass geführt ist. Eine Verbesserung der Geräuschdämpfung wird dadurch erreicht, dass der Strömungsraum direkt mit dem Auslass verbunden und die äußere Gehäusekapsel mittels an ihrem Außenumfang angeordneter, geräuschdämpfender Abstützmittel im Staubsaugergehäuse abgestützt gehalten ist.The German patent application DE 41 00 858 A1 describes a vacuum cleaner with a blower unit, which is surrounded by an inner housing capsule, which is in turn leaving a flow space in an outer housing capsule between which and the housing of the vacuum cleaner, there is a free space in which vacuum cleaner generated by the blower unit air flow through the Flow space is guided to a provided on the vacuum cleaner housing outlet. An improvement of the noise attenuation is achieved in that the flow space is connected directly to the outlet and the outer housing capsule is held supported by means arranged on its outer circumference, noise-damping support means in the vacuum cleaner housing.

In der Deutschen Patentanmeldung DE 198 43 719 A1 ist ein Staubsauger beschrieben, dessen Gebläsemotor von einer Motorabdeckung umschlossen ist und bei welchem Geräusch dämpfende Materialien an der Innen- und Außenseite der Motorabdeckung vorgesehen sind. Bei dieser Art eines Staubsaugers werden die Schwingungen des Gebläsemotors direkt auf das Staubsaugergehäuse übertragen. Das Staubsaugergehäuse wird durch diese Schwingungen angeregt, was sich in einer als unangenehm empfundenen Geräuschentwicklung äußert. Trotz der an der Innen- und Außenseite angeordneten Geräusch dämpfenden Materialien ist hier also trotzdem eine signifikante Geräuschentwicklung vorhanden.In the German patent application DE 198 43 719 A1 a vacuum cleaner is described, the blower motor is enclosed by an engine cover and in which noise damping materials are provided on the inside and outside of the engine cover. In this type of vacuum cleaner, the vibrations of the fan motor are transmitted directly to the vacuum cleaner housing. The vacuum cleaner housing is excited by these vibrations, which manifests itself in a perceived as unpleasant noise. Despite the arranged on the inside and outside noise damping materials so here is still a significant noise development available.

Dies ist ein Zustand, den es zu verbessern gilt.This is a condition to be improved.

ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION

Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine verbesserte Motoranordnung für ein Haushaltsgerät zur Verfügung zu stellen.Against this background, the present invention has the object to provide an improved engine assembly for a household appliance available.

Diese Aufgabe wird erfindungsgemäß durch eine Motoranordnung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a motor assembly with the features of claim 1.

Demgemäß ist eine Motoranordnung für ein elektromotorisch angetriebenes Haushaltsgerät vorgesehen, insbesondere für einen Staubsauger, mit einem Gehäuse, mit einer Motorkapsel, mit einem Gebläsemotor, der im montierten Zustand innerhalb des Gehäuses und der Motorkapsel angeordnet ist und von diesen umgeben (vorzugsweise vollständig umschlossen) ist, mit einem Dämpfungselement, welches konturgebunden zwischen dem Gehäuse und dem Gebläsemotor angeordnet ist und welches dazu ausgelegt ist und angeordnet ist, vom Gebläsemotor auf das Gehäuse übertragene Schwingungen zu dämpfen.Accordingly, a motor assembly for an electric motor-driven household appliance is provided, in particular for a vacuum cleaner, with a housing, with a motor capsule, with a blower motor, which is arranged in the mounted state within the housing and the motor capsule and surrounded by these (preferably completely enclosed) , comprising a damping element, which is arranged contour-bound between the housing and the blower motor and which is designed and arranged to dampen vibrations transmitted from the blower motor to the housing.

Die der vorliegenden Erfindung zugrunde liegende Idee besteht darin, den Gebläsemotor von dem Gehäuse mittels eines konturgebundenen Dämpfungselementes zu entkoppeln. Das Dämpfungselement liegt konturgebunden an jeweilige Anlageflächen des Gebläsemotors und des Gehäuses an und soll dabei vom Gebläsemotor verursachte Schwingungen aufnehmen und damit dämpfen.The idea underlying the present invention is to decouple the fan motor from the housing by means of a contour-bound damping element. The damping element is contour-bound to respective contact surfaces of the fan motor and the housing and is intended to absorb the vibration caused by the fan motor and thus dampen.

Konturgebunden bedeutet in diesem Zusammenhang, dass das Dämpfungselement das Motorgehäuse des Gebläsemotors zumindest teilweise umschließt und weitestgehend die gleiche Form wie derjenige Teil bzw. diejenigen Außenflächen des Motorgehäuses des Gebläsemotors aufweist, an welchem es anliegt. Auf diese Weise können Schwingungen des Gebläsemotors gedämpft werden, da keine Spalte und Schlitze zwischen dem Motorgehäuse und dem Dämpfungselement einerseits und zwischen dem Dämpfungselement und dem Gehäuse andererseits vorhanden sind, sodass die erzeugten Schwingungen direkt von dem Dämpfungselement aufgenommen werden können. Das Dämpfungselement weist zu diesem Zweck ein Material auf, welches möglichst gute Dämpfungseigenschaften aufweist.Contour-bound means in this context that the damping element at least partially surrounds the motor housing of the fan motor and largely has the same shape as that part or those outer surfaces of the motor housing of the fan motor on which it rests. In this way, vibrations of the fan motor can be damped, since there are no gaps and slots between the motor housing and the damping element on the one hand and between the damping element and the housing on the other hand, so that the vibrations generated can be absorbed directly by the damping element. The damping element has for this purpose a material which has the best possible damping properties.

Zur zusätzlichen Geräuschreduktion ist der Gebläsemotor im Inneren einer mit dem Gehäuse montierten Motorkapsel angeordnet. Eine solche Motorkapsel ist ein Bauteil einer Motoranordnung, welche zur Dämmung der vom Gebläsemotor ausgehenden Geräuschemissionen dient. Diese Motorkapsel ist vorzugsweise ebenfalls direkt an dem Dämpfungselement angeordnet und dämpft die Geräuschemission des Gebläsemotors zusätzlich.For additional noise reduction, the fan motor is mounted inside a motorized capsule mounted to the housing. Such a motor capsule is a component of a motor assembly, which serves for the insulation of the emissions from the fan motor. This motor capsule is preferably also arranged directly on the damping element and attenuates the noise emission of the fan motor in addition.

Vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus den weiteren Unteransprüchen sowie aus der Beschreibung unter Bezugnahme auf die Figuren der Zeichnung.Advantageous embodiments and further developments will become apparent from the other dependent claims and from the description with reference to the figures of the drawing.

In einer weiteren bevorzugten Ausführungsform weist der Gebläsemotor einen (a-seitigen) Gehäusedeckel auf und das Dämpfungselement weist eine Innenkontur auf, welche der Außenkontur des Gehäusedeckels entspricht. Vorzugsweise umschließt das Dämpfungselement den Gehäusedeckel des Gebläsemotors zu einem Großteil. Auf diese Weise lassen sich Motorschwingungen, insbesondere in axialer und in radialer Richtung, sehr gut dämpfen.In a further preferred embodiment, the blower motor has an (a-side) housing cover and the damping element has an inner contour which corresponds to the outer contour of the housing cover. Preferably, the damping element surrounds the housing cover of the fan motor to a large extent. In this way, engine vibrations, especially in the axial and in the radial direction, dampen very well.

In einer bevorzugten Ausführungsform ist das Dämpfungselement bündig an der A-Seite des Gebläsemotors angeordnet oder angebracht. Die A-Seite des Gebläsemotors bezeichnet diejenige Seite, an welcher die Antriebswelle des Gebläsemotors aus dem Gebläsemotor heraustritt und welche somit die Antriebsseite bezeichnet. Bündig bedeutet z.B., dass das Dämpfungselement im direkten Kontakt an Außenflächen des Gebläsemotors anliegt und dass keine weiteren Bauteile, Elemente oder etwa ein Spalt zwischen dem Gebläsemotor und dem Dämpfungselement vorhanden sind.In a preferred embodiment, the damping element is arranged or mounted flush with the A-side of the fan motor. The A-side of the blower motor refers to the side on which the drive shaft of the blower motor emerges from the blower motor and which thus designates the drive side. Flushing means, for example, that the damping element is in direct contact with outer surfaces of the fan motor and that there are no other components, elements or a gap between the fan motor and the damping element.

In der erfindungsgemäßen Ausführungsform weist das Gehäuse eine Ausnehmung für den Gebläsemotor auf, wobei das Dämpfungselement bündig in der Ausnehmung, d.h. an Innenflächen der Ausnehmung angeordnet ist. Durch eine derartige Ausgestaltung kann das Dämpfungselement besonders gut Schwingungen absorbieren, da das Dämpfungselement sicher und positionsgenau in der Ausnehmung angeordnet ist.In the embodiment according to the invention, the housing has a recess for the fan motor, wherein the damping element is arranged flush in the recess, ie on inner surfaces of the recess. By such a configuration, the damping element can absorb vibrations particularly well, since the damping element is arranged securely and positionally accurate in the recess.

In einer weiteren bevorzugten Ausführungsform ist das Dämpfungselement aus einem elastischen Kunststoff, vorzugsweise aus PUR, ausgebildet. PUR (Polyurethane) eignet sich besonders gut zur Ausbildung des Dämpfungselementes, da es eine sehr hohe mechanische Verschleißbeständigkeit aufweist, zudem gegenüber den meisten Schmiermittel und Schmierfetten unempfindlich ist und gute Dämpfungseigenschaften aufweist. Als Material für das Dämpfungselement können jedoch auch andere elastische Materialien verwendet werden, welche gute Dämpfungseigenschaften aufweisen, beispielsweise federelastische Elemente, eine federelastische Aufhängung und dergleichen.In a further preferred embodiment, the damping element is made of an elastic plastic, preferably made of PUR. PUR (polyurethanes) is particularly suitable for the formation of the damping element, since it has a very high mechanical wear resistance, is also insensitive to most lubricants and greases and has good damping properties. As the material for the damping element but other elastic materials can be used, which have good damping properties, such as elastic elements, a resilient suspension and the like.

In einer weiteren bevorzugten Ausführungsform weist das Gehäuse eine Positioniereinrichtung auf, an welcher das Dämpfungselement und die Motorkapsel bezüglich des Gehäuses positioniert sind. Beispielsweise weist das Gehäuse eine Vielzahl von Vorsprüngen auf, welche in entsprechende Ausnehmungen in dem Dämpfungselement und in der Motorkapsel eingreifen. Durch die Positioniereinrichtung kann sichergestellt werden, dass das Dämpfungselement und die Motorkapsel stets in einer bezüglich der Dämpfungswirkung optimalen Position in dem Gehäuse angeordnet sind.In a further preferred embodiment, the housing has a positioning device, on which the damping element and the motor capsule are positioned relative to the housing. For example, the housing has a plurality of projections, which engage in corresponding recesses in the damping element and in the motor capsule. The positioning device can ensure that the damping element and the motor capsule are always arranged in an optimum position with respect to the damping effect in the housing.

In einer weiteren bevorzugten Ausführungsform ist eine Fixiereinrichtung vorgesehen, welche das Dämpfungselement, den Gebläsemotor und/oder die Motorkapsel bezüglich des Gehäuses fixieren. Beispielsweise weist die Fixiereinrichtung eine Vielzahl von Fixierstiften auf, welche sich durch das Gehäuse, durch das Dämpfungselement, durch den Gebläsemotor und/oder durch die Motorkapsel erstrecken. Auf diese Weise kann sichergestellt werden, dass das Dämpfungselement, die Motorkapsel bzw. der Motor verdrehsicher und schwingungssicher an dem Gehäuse fixiert sind. In einer bevorzugten Ausführungsform verspannt die Fixiereinrichtung den Motor zwischen dem Gehäuse und der Motorkapsel, sodass das Dämpfungselement vorgespannt ist. Durch diese Ausgestaltung können Schwingungen des Gebläsemotors besonders gut von dem Dämpfungselement absorbiert werden.In a further preferred embodiment, a fixing device is provided, which fix the damping element, the fan motor and / or the motor capsule with respect to the housing. For example, the fixing device has a multiplicity of fixing pins which extend through the housing, through the damping element, through the fan motor and / or through the motor capsule. In this way it can be ensured that the damping element, the motor capsule or the motor are fixed against rotation and vibration safe to the housing. In a preferred embodiment, the fixing device braces the motor between the housing and the motor capsule, so that the damping element is biased. Due to this configuration, vibrations of the fan motor can be absorbed particularly well by the damping element.

In einer weiteren bevorzugten Ausführungsform ist die Dämpfung des Dämpfungselementes einstellbar. Beispielsweise kann die Härte und/oder das Elastizitätsmodul des Dämpfungselementes derart verändert werden, das diese optimal auf die vom Gebläsemotor erzeugten dominanten Schwingungsfrequenzen abgestimmt sind. Auch kann die Größe und die Masse des Dämpfungselementes an die jeweiligen Randbedingen, insbesondere die Größe und den Drehzahlbereich des Gebläsemotors, angepasst werden. Auf diese Weise kann die erfindungsgemäße Motoranordnung in unterschiedlichen Konstruktionen und Bauweisen von Staubsaugern und Haushaltsgeräten angewendet werden.In a further preferred embodiment, the damping of the damping element is adjustable. For example, the hardness and / or the modulus of elasticity of the damping element can be changed in such a way that it optimally are tuned to the dominant vibration frequencies generated by the fan motor. Also, the size and mass of the damping element to the respective boundary conditions, in particular the size and the speed range of the fan motor, can be adjusted. In this way, the engine assembly according to the invention can be applied in different constructions and designs of vacuum cleaners and household appliances.

In einer weiteren bevorzugten Ausführungsform ist zumindest ein weiteres Dämpfungselement vorgesehen, welches an der dem Dämpfungselement gegenüberliegende Seite des Gebläsemotors, z.B. an der B-Seite des Gebläsemotors, zwischen Gebläsemotor und Motorkapsel angeordnet ist.

BESCHREIBUNG VON AUSFÜHRUNGSBEISPIELENDESCRIPTION OF EMBODIMENTS

Figur 1 zeigt eine perspektivische Explosionsansicht einer erfindungsgemäßen Motoranordnung 1. Die Motoranordnung 1 weist ein Gehäuse 2, ein Dämpfungselement 3, einen Gebläsemotor 4 und eine Motorkapsel 5 auf. Das Gehäuse 2 ist beispielsweise ein Teil eines hier nicht dargestellten Staubsaugergehäuses. Das Gehäuse 2 weist eine Ausnehmung 22 auf. In dieser Ausnehmung 22 ist das Dämpfungselement 3 konturgebunden angeordnet. Eine Öffnung 6 des Gehäuses 2 ist zu einer Öffnung 10 des Dämpfungselements 3 fluchtend ausgerichtet. Auf dem Dämpfungselement 3 ist der Gebläsemotor 4 ebenfalls konturgebunden angeordnet. Durch die Öffnungen 6, 10 erstreckt sich im montierten Zustand der Motoranordnung die Antriebswelle des Gebläsemotors. Vorzugsweise wird der Gebläsemotor 4 A-seitig an das Dämpfungselement 3 angekoppelt. A-seitig bedeutet, dass der Motor mit seiner Antriebsseite (an welcher sich die Antriebswelle mit dem Gebläse nach außen erstreckt) an dem Dämpfungselement angeordnet ist. Der Gebläsemotor 4 wird von der Motorkapsel 5 umschlossen. Die Motorkapsel 5 ist ebenfalls, wie der Gebläsemotor 4, mit dem Dämpfungselement 3 direkt und konturgebunden gekoppelt. FIG. 1 shows an exploded perspective view of a motor assembly according to the invention 1. The motor assembly 1 comprises a housing 2, a damping element 3, a fan motor 4 and a motor capsule 5 on. The housing 2 is for example a part of a vacuum cleaner housing, not shown here. The housing 2 has a recess 22. In this recess 22, the damping element 3 is arranged contour-bound. An opening 6 of the housing 2 is aligned with an opening 10 of the damping element 3. On the damping element 3, the fan motor 4 is also arranged contour-bound. Through the openings 6, 10 extends in the mounted state of the motor assembly, the drive shaft of the fan motor. Preferably, the fan motor 4 is coupled on the A side to the damping element 3. A-side means that the motor with its drive side (at which the drive shaft with the fan extends to the outside) is arranged on the damping element. The fan motor 4 is enclosed by the motor capsule 5. The motor capsule 5 is also, like the fan motor 4, coupled to the damping element 3 directly and contour-bound.

Ferner ist aus Fig. 1 erkennbar, dass in der Ausnehmung 22 des Gehäuses 2 eine Positioniereinrichtung 7 vorgesehen ist, mit welcher das Dämpfungselement 3 in dem Gehäuse 2 positioniert wird. Die Positioniereinrichtungen 7 ist durch drei Vorsprünge ausgebildet, welche sich durch Ausnehmungen 8 im Dämpfungselement 3 und durch Ausnehmungen 9 in der Motorkapsel erstrecken. Durch die Ausnehmungen 8, 9 können sich auch Fixierstifte 15 erstrecken, welche den Gebläsemotor 4 zwischen dem Gehäuse 2 und der Motorkapsel 5 verspannen und welche das Dämpfungselement 3 verspannen.Furthermore, it is off Fig. 1 recognizable that in the recess 22 of the housing 2, a positioning device 7 is provided, with which the damping element 3 is positioned in the housing 2. The positioning means 7 is formed by three projections which extend through recesses 8 in the damping element 3 and through recesses 9 in the motor capsule. Through the recesses 8, 9 also fixing pins 15 may extend, which clamp the fan motor 4 between the housing 2 and the motor capsule 5 and which clamp the damping element 3.

Durch eine derartige Ausbildung einer Motoranordnung kann der Gebläsemotor 4 vollständig von dem Gehäuse 2 schwingungsisoliert werden. Somit werden keine Schwingungen vom Gebläsemotor 4 auf das Gehäuse 2 übertragen, wodurch die Geräuschabstrahlung des Haushaltsgerätes weitgehendst unterdrückt wird.Such a design of a motor assembly, the fan motor 4 can be completely isolated from the housing 2 vibration isolation. Thus, no vibrations are transmitted from the fan motor 4 to the housing 2, whereby the noise emission of the household appliance is largely suppressed.

Für das Dämpfungselement 3 ist vorzugsweise ein Material vorgesehen, welches gute Dämpfungseigenschaften aufweist. Beispielsweise ist das Dämpfungselement 3 aus Polyurethan ausgebildet. Jedoch kommen auch andere Kunststoffe, insbesondere thermoplastische und/oder duroplastische und/oder thermoelastische Kunststoffe, für die Ausbildung des Dämpfungselementes 3 in Frage.For the damping element 3, a material is preferably provided which has good damping properties. For example, the damping element 3 is formed of polyurethane. However, other plastics, in particular thermoplastic and / or thermoset and / or thermoelastic plastics, come for the formation of the damping element 3 in question.

Aus Fig. 2 ist ersichtlich, dass der Gebläsemotor 4 konturgebunden an dem Dämpfungselement 3 anliegt. Das Dämpfungselement 3 liegt dabei an der Mantelfläche 17 des Gebläsemotors 4 mit der Kontaktzone 18 an. Ferner liegt der Gebläsemotor 4 an einer Aushalsung 20 an der Innenseite 19 der Öffnung 6 des Dämpfungselementes 3 an. Das Motorgehäuse liegt an seiner Stirnfläche 11 an einer Stirnfläche 12 des Dämpfungselementes 3 an.Out Fig. 2 It can be seen that the fan motor 4 bears contour-bound on the damping element 3. The damping element 3 is applied to the lateral surface 17 of the fan motor 4 with the contact zone 18 at. Furthermore, the blower motor 4 abuts against a neck 20 on the inner side 19 of the opening 6 of the damping element 3. The motor housing rests against an end face 12 of the damping element 3 on its end face 11.

An dem Gebläsemotor 4 ist hier ein Vorsprung 14 ausgebildet, welcher sich in eine Ausnehmung 13 des Dämpfungselementes 3 erstreckt. Der Vorsprung 14 erstreckt sich über die gesamte Stirnfläche 11 des Gebläsemotors 4 und greift in die Ausnehmung 13 des Dämpfungselementes 3, welche entsprechend dem Vorsprung 14 ausgebildet ist, ein. Durch diesen Vorsprung 14 und dieser Ausnehmung 13 wird der Gebläsemotors 4 bezüglich des Dämpfungselementes 3 zentriert. Somit bleibt die Position des Gebläsemotors 4 bezüglich des Dämpfungselementes 3 stets gleich.On the blower motor 4, a projection 14 is formed here, which extends into a recess 13 of the damping element 3. The projection 14 extends over the entire end face 11 of the fan motor 4 and engages in the recess 13 of the damping element 3, which is formed according to the projection 14, a. By this projection 14 and this recess 13 of the fan motor 4 is centered with respect to the damping element 3. Thus, the position of the fan motor 4 with respect to the damping element 3 always remains the same.

Aus Fig. 2 ist ferner ersichtlich, dass das Dämpfungselement 3 den Gebläsemotor 4 sowohl axial als auch radial umgibt, sodass in alle Raumrichtungen gerichtete Schwingungen des Gebläsemotors 4 aufgenommen werden können.Out Fig. 2 It can also be seen that the damping element 3 surrounds the fan motor 4 both axially and radially, so that vibrations of the fan motor 4 directed in all directions in space can be accommodated.

Fig.3 zeigt ein Schnittbild einer Motoranordnung 1 im montierten Zustand und Fig. 4 zeigt eine perspektivische Ansicht einer Motoranordnung im montierten Zustand. Die Motorkapsel 5 ist hier direkt mit dem Dämpfungselement 3 gekoppelt und liegt konturgebunden an diesen an. Der Gebläsemotor 4 ist ferner direkt mit dem Dämpfungselement 3 gekoppelt. Figure 3 shows a sectional view of a motor assembly 1 in the assembled state and Fig. 4 shows a perspective view of a motor assembly in the mounted state. The motor capsule 5 is here coupled directly to the damping element 3 and lies contour-bound to this. The blower motor 4 is further coupled directly to the damping element 3.

In diesem Ausführungsbeispiel ist innerhalb der Motorkapsel 5 ein weiteres Dämpfungselement 23 an der B-Seite des Gebläsemotors 4 angeordnet. Das weitere Dämpfungselement 23 hat - wie das Dämpfungselement 3 - die Aufgabe zu verhindern, dass Schwingungen des Gebläsemotors 4 auf das Gehäuse 2 übertragen werden. Das weitere Dämpfungselement 23 ist - wie das Dämpfungselement 3 - aus einem elastischen Material, wie z.B. Polyurethan.In this embodiment, a further damping element 23 is arranged on the B side of the fan motor 4 within the motor capsule 5. The further damping element 23 has - as the damping element 3 - to prevent the task that vibrations of the fan motor 4 are transmitted to the housing 2. The further damping element 23, like the damping element 3, is made of an elastic material, e.g. Polyurethane.

In der Darstellung in Fig. 3 ist erkennbar, dass der Motor zwischen dem Dämpfungselement 3 und der Motorkapsel 5 verspannt ist. Beispielsweise werden Fixierstifte 15 in die Ausnehmungen 8, 9 des Dämpfungselementes 3 und der Motorkapsel 5 geführt und können von außen verspannt werden.In the illustration in Fig. 3 It can be seen that the motor between the damping element 3 and the engine capsule 5 is braced. For example, fixing pins 15 are guided in the recesses 8, 9 of the damping element 3 and the motor capsule 5 and can be clamped from the outside.

Die Motorkapsel 5 der Motoranordnung 1 weist in diesem Ausführungsbeispiel zudem Verstärkungsrippen 21 auf, welche die Stabilität der Motorkapsel 5 erhöhen. Somit werden auch die Schwingungen der Motorkapsel 5 reduziert.The motor capsule 5 of the motor assembly 1 in this embodiment also has reinforcing ribs 21, which increase the stability of the motor capsule 5. Thus, the vibrations of the engine capsule 5 are reduced.

Obwohl die vorliegende Erfindung anhand bevorzugter Ausführungsbeispiele vorstehend vollständig beschrieben wurde, ist sie darauf nicht beschränkt, sondern auf vielfältige Art und Weise modifizierbar.
Beispielsweise ist die Erfindung nicht ausschließlich auf als Staubsauger ausgebildete Haushaltsgeräte beschränkt, sondern lässt sich auch bei anderen elektromotorisch angetrieben Haushaltsgeräten vorteilhaft einsetzen, beispielsweise bei Entsaftern, Kaffeevollautomaten, Küchenmaschinen, etc.Although the present invention has been fully described above with reference to preferred embodiments, it is not limited thereto but is modifiable in a variety of ways.
For example, the invention is not limited exclusively to designed as a vacuum cleaner household appliances, but can also be used advantageously in other electric motor driven household appliances, such as juicers, coffee machines, food processors, etc.
