Description

Die Erfindung betrifft einen Staubsauger mit einem Gehäuse und einem darin aufgenommenen Elektromotor.The invention relates to a vacuum cleaner with a housing and an electric motor received therein.

Bei bekannten Staubsaugern gestaltet sich die Montage des Elektromotors und dessen Komponenten im Inneren des Staubsaugergehäuses oftmals kompliziert und zeitaufwendig. Es müssen hierzu zumeist mehrere Befestigungsmittel, wie Platten, Klemmen und dergleichen Elemente, verwendet werden. Gemäß DE 195 07 270 C5 ist der Elektromotor unter Zwischenordnung schwingungsdämpfender Elemente in einem weiteren dünnwandigen Motorgehäuse aufgenommen, welches unter Zwischenordnung weiterer schwingungsdämpfender Elemente in dem Staubsaugergehäuse angeordnet ist.In known vacuum cleaners, the assembly of the electric motor and its components in the interior of the vacuum cleaner housing is often complicated and time consuming. For this purpose, it is usually necessary to use a plurality of fastening means, such as plates, clamps and the like elements. According to DE 195 07 270 C5 the electric motor is accommodated with the interposition of vibration damping elements in a further thin-walled motor housing, which is arranged in the vacuum cleaner housing with the interposition of further vibration-damping elements.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Anordnung und Montage eines Elektromotors in einem Staubsauger zu vereinfachen.The present invention has for its object to simplify the arrangement and assembly of an electric motor in a vacuum cleaner.

Diese Aufgabe wird bei einem gattungsgemäßen Staubsauger erfindungsgemäß dadurch gelöst, dass der Elektromotor in einer den Elektromotor zumindest teilweise umgebenden Kapselung aus einem formstabilen, schalldämmenden geschäumten Material einer Wandstärke von wenigstens 10 mm aufgenommen ist, wobei die Kapselung nicht Teil des Elektromotors ist, und dass die so gebildete Einheit aus Elektromotor und Kapselung in einen komplementär zu der Einheit ausgebildeten Aufnahmeraum in dem Gehäuse eingesetzt ist und vorzugsweise ohne weitere Befestigungsmittel zu erfordern formschlüssig in dem Gehäuse angeordnet ist.This object is achieved in a generic vacuum cleaner according to the invention that the electric motor is housed in a surrounding the electric motor at least partially encapsulation of a dimensionally stable, sound-insulating foamed material of a wall thickness of at least 10 mm, the encapsulation is not part of the electric motor, and that the thus formed unit of electric motor and encapsulation is inserted into a receiving space formed complementary to the unit in the housing and preferably without requiring further fastening means is positively arranged in the housing.

Es wird also erfindungsgemäß vorgeschlagen, dass der Elektromotor vermittels der Kapselung in dem Staubsaugergehäuse in seiner bestimmungsgemäßen Position angeordnet wird und in dieser bestimmungsgemäßen Position dann dauerhaft, wenn auch lösbar, gehalten ist. Das formstabile geschäumte Material ist in der Lage, den hier üblicherweise auftretenden Kräften standzuhalten ohne zu verformen. Es ist auch geeignet, die Komponente Elektromotor des Staubsaugers so zu umgeben und zu fixieren, dass der Elektromotor und die Kapselung dabei selbst keinen Schaden erleiden. Hierfür haben sich (Hart)Schaummaterialien als vorteilhaft erwiesen. In besonders bevorzugter Weise können Polypropylen- (PP) oder Polyurethanschäume (PU) verwendet werden. Geschäumte Materialien einer Dichte von wenigstens 40 g/l, insbesondere 40 bis 100 g/l, und vorzugsweise 50 bis 90 g/l haben sich als besonders geeignet erwiesen. Schäume sind zudem schalldämmend und daher für diese Anwendung vorteilhaft.It is therefore proposed according to the invention that the electric motor is arranged by means of the encapsulation in the vacuum cleaner housing in its intended position and in this intended position then permanently, albeit releasably held. The dimensionally stable foamed material is able to withstand the forces normally occurring here without deforming. It is also suitable to surround and fix the component electric motor of the vacuum cleaner in such a way that the electric motor and the encapsulation themselves do not suffer any damage. For this purpose, (hard) foam materials have proven to be advantageous. In a particularly preferred manner, polypropylene (PP) or polyurethane foams (PU) can be used. Foamed materials having a density of at least 40 g / l, in particular 40 to 100 g / l, and preferably 50 to 90 g / l have proven to be particularly suitable. Foams are In addition, sound-absorbing and therefore advantageous for this application.

Der Begriff Kapselung bedeutet im Sinne der vorliegenden Erfindung, dass ein Formkörper aus einem geeigneten geschäumten und formstabilen Material den Elektromotor zumindest teilweise so umgibt, dass der Elektromotor durch den Formkörper in seiner bestimmungsgemäßen Montageposition in dem Staubsaugergehäuse verliersicher und vorzugsweise im Wesentlichen spielfrei gehalten ist, auch wenn der Staubsauger ruckartig von einem Benutzer bewegt wird. Beispielsweise müssen auch die beim stoßartigen Aufsetzen des Staubsaugers auftretenden Impulse oder Momente von der Kapselung bzw. dem Formkörper zerstörungsfrei und im Wesentlichen verwindungsfrei aufgenommen werden können. Der Elektromotor wird ferner ohne weitere Befestigungsmittel zu erfordern drehfest gehalten. Die Wandstärke der Kapselung liegt vorzugsweise durchgehend zwischen 10 - 50 mm, insbesondere 10 - 25 mm, insbesondere 10 - 20 mm und weiter insbesondere 12 - 17 mm.The term encapsulation in the context of the present invention means that a shaped body of a suitable foamed and dimensionally stable material at least partially surrounds the electric motor so that the electric motor is held captive by the molded body in its intended mounting position in the vacuum cleaner housing and preferably substantially free of play, also when the vacuum cleaner is jerkily moved by a user. For example, the impulses or moments occurring when the vacuum cleaner is placed abruptly must also be able to be absorbed by the encapsulation or the molded body in a non-destructive and essentially torsion-free manner. The electric motor is further required to require rotation without further fasteners. The wall thickness of the encapsulation is preferably continuously between 10 and 50 mm, in particular 10 to 25 mm, in particular 10 to 20 mm and more particularly 12 to 17 mm.

Vorzugsweise ist die Einheit aus Elektromotor und Kapselung so ausgebildet, dass sie, ohne weitere Befestigungsmittel zu erfordern, formschlüssig in dem Gehäuse angeordnet ist.Preferably, the unit of electric motor and encapsulation is designed so that it, without requiring further fastening means, is arranged in a form-fitting manner in the housing.

Die Kapselung kann beispielsweise einteilig ausgebildet sein und beispielsweise eine Topfform aufweisen, in welche der Elektromotor dann in axialer Richtung einsetzbar ist. Die Kapselung kann aber auch in vorteilhafter Weise zwei Halbschalenteile umfassen, in deren Trennebene die Längsachse des Elektromotors verläuft.The encapsulation may for example be formed in one piece and, for example, have a pot shape, in which the electric motor is then used in the axial direction. However, the encapsulation can also advantageously comprise two half-shell parts, in the parting plane of which runs the longitudinal axis of the electric motor.

Nach einer bevorzugten Ausführungsform des erfindungsgemäßen Staubsaugers stützt sich der Elektromotor zwischen der Kapselung und einem Flanschabschnitt des Gehäuses ab.According to a preferred embodiment of the vacuum cleaner according to the invention, the electric motor is supported between the enclosure and a flange portion of the housing.

In Weiterbildung dieses Erfindungsgedankens erweist es sich als besonders vorteilhaft, wenn der Elektromotor eine integrierte Turbineneinheit aufweist und sich mit einem Ansaugbereich der Turbineneinheit gegen den genannten Flanschabschnitt abstützt. Dieser Flanschabschnitt begrenzt vorzugsweise unmittelbar einen Ansaugraum des Staubsaugers, in welchen ein Staubsaugerschlauch einmündet. Somit kann der Elektromotor mit integrierter Turbineneinheit unmittelbar Luft aus dem Saugraum ansaugen. Durch Einsetzen der Einheit aus Elektromotor und Kapselung in die bestimmungsgemäße Montageposition ist also nicht nur der Elektromotor in einer bestimmungsgemäßen Monateposition fixiert, sondern auch der Anschluss der Turbineneinheit an den Saugraum des Staubsaugers erreicht.In a further development of this inventive idea, it proves to be particularly advantageous if the electric motor has an integrated turbine unit and is supported with a suction region of the turbine unit against said flange portion. This flange portion preferably limits directly a suction chamber of the vacuum cleaner, in which a vacuum cleaner hose opens. Thus, the electric motor with integrated turbine unit can directly suck in air from the suction chamber. By inserting the unit of electric motor and encapsulation in the intended mounting position so not only the electric motor is fixed in a proper month position, but also reached the connection of the turbine unit to the suction chamber of the vacuum cleaner.

Im Hinblick auf eine optimale Schalldämmung erweist es sich als vorteilhaft, dass die Kapselung eine mehrfache Umlenkung der angesaugten Luft bewirkt. Sie weist wenigstens eine Öffnung auf, um angesaugte Luft in Längsrichtung des Gehäuses weiterzuleiten.With regard to an optimal sound insulation, it proves to be advantageous that the enclosure causes a multiple deflection of the sucked air. It has at least one opening to forward sucked air in the longitudinal direction of the housing.

Es erweist sich auch als vorteilhaft, wenn zwischen Kapselung und Elektromotor wenigstens abschnittsweise ein Zwischenraum ausgebildet ist, da dieser zur Kühlung und/oder Luftführung dienen kann.It also proves to be advantageous if, at least in sections, a gap is formed between the encapsulation and the electric motor, since this can serve for cooling and / or air guidance.

Der Elektromotor kann des weiteren über Positionierungsmittel, beispielsweise über in Eingriff miteinander befindliche Vorsprünge und Ausnehmungen, in vorbestimmter Anordnung verdrehsicher an der Kapselung gehalten sein.Furthermore, the electric motor can be held in a predetermined arrangement against rotation by means of positioning means, for example via projections and recesses which are in engagement with one another, against the encapsulation.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aus den beigefügten Patentansprüchen und aus der zeichnerischen Darstellung und nachfolgenden Beschreibung einer bevorzugten Ausführungsform der Erfindung.Further features, details and advantages of the invention will become apparent from the appended claims and from the drawings and the following description of a preferred embodiment of the invention.

Figur 1 zeigt schematisch angedeutet einen insgesamt mit dem Bezugszeichen 2 bezeichneten Staubsauger mit einem Gehäuse 4 und einem darin aufgenommenen Elektromotor 6. Der Elektromotor 6 bildet mit einer Kapselung 8 aus einem formstabilen und schalldämmenden Material eine Einheit 10 (s. Figur 2), die als solche in das Innere des Gehäuses 4 einsetzbar ist. Bei dem formstabilen und schalldämmenden Material handelt es sich vorzugsweise um einen (Hart)Schaum, insbesondere auf PP- oder PU-Basis, der einfach herstellbar ist und hervorragende tragende und schalldämmende Eigenschaften aufweist. Eine Dichte von ca. 60 g/l hat sich als besonders geeignet erwiesen.1 schematically shows a vacuum cleaner designated as a whole by the reference numeral 2 with a housing 4 and an electric motor 6 accommodated therein. The electric motor 6 forms an encapsulation 8 of a dimensionally stable and sound-insulating material, a unit 10 (see FIG such is inserted into the interior of the housing 4. The dimensionally stable and sound-insulating material is preferably a (hard) foam, in particular PP or PU-based, which is easy to produce and has excellent load-bearing and sound-insulating properties. A density of about 60 g / l has proven to be particularly suitable.

Die Einheit 10 ist formschlüssig, ohne weitere Befestigungsmittel, wie Schrauben, Laschen oder Bleche zu erfordern, in einem komplementär ausgebildeten Aufnahmeraum 12 des Staubsaugergehäuses 4 im Wesentlichen spielfrei aufgenommen. Bei der Montage des Staubsaugers wird also die Einheit 10 in den Aufnahmeraum 12 eingesetzt, der dann durch eine oder mehrere Gehäusekomponenten verschlossen wird. Allein durch die Kapselung 8 ist der Elektromotor 6 in der bestimmungsgemäßen Montageposition im Gehäuse 4 des Staubsaugers fixiert.The unit 10 is positively, without requiring further fastening means, such as screws, tabs or plates, in a complementary design receiving space 12 of the vacuum cleaner housing 4 substantially free of play added. When mounting the vacuum cleaner so the unit 10 is inserted into the receiving space 12, which is then closed by one or more housing components. Solely by the encapsulation 8 of the electric motor 6 is fixed in the intended mounting position in the housing 4 of the vacuum cleaner.

Im beispielhaft dargestellten Fall umfasst die Kapselung 8 an einer Stirnseite 14 einen dom- oder stiftförmigen Vorsprung 16, der in eine komplementäre Ausnehmung 18 in einem Wandabschnitt 20 des Gehäuses 4 eingreift. Die Kapselung 8 stützt sich ferner über einen beispielhaft umlaufenden Flanschabschnitt 22 (s. auch Figur 3) gegen eine den Aufnahmeraum 12 begrenzende Wandung des Gehäuses 4 ab. Er ist hierdurch in der vertikalen Ebene vollständig gestützt und in seiner Lage fixiert.In the case illustrated by way of example, the encapsulation 8 comprises on an end face 14 a domed or pin-shaped projection 16 which engages in a complementary recess 18 in a wall section 20 of the housing 4. The encapsulation 8 is further supported by way of an exemplary circumferential flange section 22 (see also FIG. 3) against a wall of the housing 4 delimiting the receiving space 12. He is thereby fully supported in the vertical plane and fixed in its position.

Auf der von der Stirnseite 14 abgewandten und zu einem Saugraum 24 zugewandten Seite stützt sich die Einheit 10 aus Elektromotor und Kapselung über eine mit dem Elektromotor 6 integrierte Turbineneinheit 26 gegen eine Trennwand 28 des Staubsaugers 2 ab. Diese Trennwand 28 trennt den Motorraum 30 von dem Saugraum 24. Die Turbineneinheit 26 ist im beispielhaft dargestellten Fall mit dem Elektromotor 6 unmittelbar integriert, und die Turbineneinheit stützt sich im beispielhaft dargestellten Fall über einen Dichtring 32 gegen die Trennwand 28 unmittelbar um eine Ansaugöffnung 34 herum ab. Hierdurch ist mit dem Vorgang des Einsetzens der Einheit 10 in den Aufnahmeraum 12 zugleich eine Verbindung zwischen der Turbineneinheit 26 und dem Ansaugraum 24 des Staubsaugers erreicht.On the side facing away from the end face 14 and facing a suction chamber 24 side, the unit 10 is supported by electric motor and encapsulation via a turbine unit 26 integrated with the electric motor 6 against a partition wall 28 of the vacuum cleaner 2. This partition wall 28 separates the engine compartment 30 from the suction chamber 24. The turbine unit 26 is directly integrated with the electric motor 6 in the case exemplified, and the turbine unit is supported in the case exemplified by a sealing ring 32 against the partition wall 28 immediately around an intake opening 34 from. As a result, with the operation of inserting the unit 10 in the receiving space 12 at the same time a connection between the turbine unit 26 and the suction chamber 24 of the vacuum cleaner is achieved.

Die Figuren 3 bis 7 zeigen eine beispielhafte und vorteilhafte Ausführungsform des die Kapselung 8 bildenden Formkörpers 35. Er ist im beispielhaften Fall einstückig und im Wesentlichen topfförmig ausgebildet. Am Boden 36 der Topfform der Kapselung 8 erkennt man Vorsprünge 38 (die auch aus Figuren 1 und 2 ersichtlich sind), welche in komplementäre Öffnungen 40 einer Stirnseite des Elektromotors 6 eingreifen und auf diese Weise den Elektromotor 6 in einer bestimmungsgemäßen Position gegenüber der Kapselung 8 halten. Sie bilden Positionierungsmittel. Der Elektromotor wird dadurch verdrehsicher in der Kapselung gehalten. Auf diese Weise kann auch ein Zwischenraum 42 zwischen dem Elektromotor 6 und der Kapselung 8 realisiert werden, der zur Luftkühlung und Luftführung dienen kann. Im beispielhaft dargestellten Fall wird die von der Turbineneinheit 26 angesaugte und geförderte Luft über Luftaustrittsöffnungen 44 im Gehäuse des Elektromotors 6 nach radial außen in den Zwischenraum 42 zwischen Elektromotor 6 und Kapselung 8 geleitet. Die Kapselung 8 bewirkt dann eine schalldämmende Umleitung der Luft in Richtung des Pfeils 46 und weiter in Richtung des Pfeils 48. Die Luft wird schließlich über im beispielhaft dargestellten Fall vier Öffnungen 50 in dem Flanschabschnitt 22 der Kapselung 8 in Längsrichtung des Staubsaugergehäuses 4 weitergeleitet und gelangt schließlich nach außerhalb des Staubsaugers 2.Figures 3 to 7 show an exemplary and advantageous embodiment of the encapsulation 8 forming Shaped body 35. It is in the exemplary case in one piece and substantially cup-shaped. At the bottom 36 of the cup shape of the enclosure 8 can be seen protrusions 38 (which are also apparent from Figures 1 and 2), which engage in complementary openings 40 of an end face of the electric motor 6 and in this way the electric motor 6 in a position opposite the encapsulation. 8 hold. They form positioning means. The electric motor is thereby held against rotation in the enclosure. In this way, a gap 42 between the electric motor 6 and the enclosure 8 can be realized, which can serve for air cooling and air flow. In the case illustrated by way of example, the air sucked in and conveyed by the turbine unit 26 is led via air outlet openings 44 in the housing of the electric motor 6 radially outward into the intermediate space 42 between the electric motor 6 and the encapsulation 8. The enclosure 8 then causes a sound-insulating bypass of the air in the direction of the arrow 46 and further in the direction of the arrow 48. The air is finally passed on in the example illustrated four openings 50 in the flange portion 22 of the enclosure 8 in the longitudinal direction of the vacuum cleaner housing 4 and passes finally to the outside of the vacuum cleaner. 2
