- the spacing also allows the vacuum cleaner fan seal to freely deform, thus making the dust extractor unit easy to use, with the ductility of the vacuum cleaner fan gasket capable of compensating for manufacturing tolerances of the dust extractor and blower and inaccuracies in positioning the two together after insertion by the user.
- the thickness of the membrane of the vacuum cleaner fan seal according to the invention decreases in the radial vacuum cleaner fan seal. This means that the thickness of the membrane at the transition to the inner ring is greater than the thickness of the membrane at the transition to the outer ring. Preferably, the thickness of the vacuum cleaner fan seal decreases monotonically from the inner to the outer ring. Thus, it can be ensured that in the vicinity of the inner ring, a high stability of the vacuum cleaner fan seal is given and the vacuum cleaner fan seal can withstand a frequent insertion of Staubabscheideiki unscathed. In addition, the small thickness of the membrane in the vicinity of the outer ring to the fact that the membrane can deform very easily there and - especially when the fan is switched on and resulting negative pressure - the blower can nestle well.
- the vacuum cleaner fan seal is rotationally symmetrical. Due to the rotational symmetry, the force, which is transmitted on the one hand by the negative pressure of the blower and on the other hand by the insertion and removal of Staubabscheideiki on the vacuum cleaner fan seal, can be evenly distributed. So it can be avoided that some areas of the vacuum cleaner fan seal wear out very quickly and the vacuum cleaner fan seal is destroyed after only a short use.

- the vacuum cleaner fan seal has a collar.
- the collar is closer to the inner ring than to the outer ring. It is preferred that the collar is on the tube into which the inner ring continues. Particularly preferably, the collar is attached to the outer surface of the tube. Thanks to the collar, the vacuum cleaner fan seal can be attached to a vacuum cleaner in a particularly easy way.
- the vacuum cleaner according to the invention has a groove into which the collar of the vacuum cleaner fan seal can engage.
- the attachment of the vacuum cleaner fan seal in the groove is particularly easy in the manufacturing process.
- the vacuum cleaner fan seal is fixed particularly strong in the groove.
- the Staubabscheidetician tapers on the fan-facing side.
- the preferred Staubabscheidetician tapers At the side of the Staubabscheidetician, at which there is an opening through which the air can enter the fan, the preferred Staubabscheidetician tapers.
- features are attached to the vacuum cleaner and / or the Staubabscheideisme through which an introduction path is defined, so that the Staubabscheideerne initially rests obliquely to the plane of the vacuum cleaner fan seal on the vacuum cleaner fan seal.
- the preferred Staubabscheidetician has for this purpose a rib, particularly preferably a circumferential rib.
- the preferred vacuum cleaner includes a recess into which these Rib can be introduced.
- the dust collecting unit can be inserted into the vacuum cleaner in a lever movement, that is to say in a rotation about the axis of the depression.
- the Staubabscheidetician first touches the vacuum cleaner fan seal on the side facing the recess.
- the vacuum cleaner fan seal according to the invention is particularly well suited for the one-sided application of force at first, since the vacuum cleaner fan seal is stabilized by both the inner and the outer ring.
- the invention makes it possible to produce a vacuum cleaner fan seal, which has a very good sealing effect at already very low joining force and at low pressures. This is particularly advantageous in vacuum cleaners with a low blower power, as z. B. is usually the case with battery-operated vacuum cleaners.
- the vacuum cleaner fan seal according to the invention is designed so that when joining the vacuum cleaner fan seal very little friction on the vacuum cleaner fan seal occurs, so that the vacuum cleaner fan seal undergoes little wear and can be used for a particularly long time.
- a high tolerance width is achieved by the membrane of the vacuum cleaner fan seal. This means that higher manufacturing tolerances of the vacuum cleaner parts do not lead to a loss of sealing effect.
- the sealing is not reduced by an imprecise insertion of Staubabscheideiki in the vacuum cleaner.
- FIG. 1 shows a vacuum cleaner 1 according to the invention with a suction air inlet 2, through which the suction air can enter the vacuum cleaner 1, where it is fed through a suction air duct 3 of a Staubabscheideech 4.
- the Staubabscheideech 4 includes a vortex separator 5 with a centrally located filter 6.
- the suction air is cleaned in the vortex separator 5 of dust and then passes through an outlet opening 7 of the Staubabscheideisme 4 in the inlet opening 8 of the blower 9.
- the air strikes the rotating impeller 10 and is accelerated by this, so that the air is finally carried out through air outlet openings 11 from the vacuum cleaner 1 back into the environment.
- the vacuum cleaner fan seal 12 Between the outlet opening 7 of the Staubabscheidetician and the inlet opening 8 of the blower 9 is the vacuum cleaner fan seal 12 of the invention.
- the vacuum cleaner fan seal 12 has an outer ring 13 which is rotationally symmetrical and has a rectangular cross-section.
- the vacuum cleaner fan seal 12 has an inner ring 14 which rests against the fan 9.

- the vacuum cleaner fan seal 12 also has a circumferential collar 17 which is inserted into a groove 18 in the vacuum cleaner 1 to the Vacuum cleaner fan seal 12 to fix in the vacuum cleaner 1. Moreover, in the vicinity of the inner ring 14, the vacuum cleaner fan seal 12 has a groove 19 into which the pipe 20 is inserted around the inlet port of the blower 8. Thus, a particularly good sealing effect between the vacuum cleaner fan seal 12 and the blower 9 can be achieved.
- the outer ring 13 is based on an abutment in the vacuum cleaner 1 from.
- both the outer ring 13 and the inner ring 14 act forces on the vacuum cleaner fan seal 12, which are aligned against the Staubabscheidetician 4 and thus lead to a better nestling of the vacuum cleaner fan seal 12 to the Staubabscheidetician.
- FIG. 3 is to be seen in another embodiment of the Staubabscheidetician 3 according to the invention that the outer ring 13, which is made very thin here, is not supported on a portion of the vacuum cleaner 1, but is spaced from the vacuum cleaner 1.
- the vacuum cleaner fan seal 12 is attached only to the vacuum cleaner via the inner ring 14, the collar 17, and the groove 18. This has the consequence that the vacuum cleaner fan seal 12 can nestle particularly well on the Staubabscheidetician 4, as it is designed very flexible on the one hand by the very thin outer ring 13 in particular in its outer region and through the space between the outer ring 14 and the Vacuum cleaner 1 particularly good clings to varying gap dimensions, which can be caused by manufacturing tolerances or imprecise insertion of Staubabscheidetician 4.
- the vacuum cleaner fan seal 12 as in FIG. 3 is shown, has a membrane 15 whose thickness decreases from the inner ring 14 to the outer ring 13. In this way, the close to the inner ring 14 located diaphragm 15 of the vacuum cleaner fan seal 12 can give stability, while the outer, thinner membrane can fit particularly well to the Staubabscheidetician 4.
- the Staubabscheidetician 4 has a circumferential collar 21 which can be inserted into a recess 22 in the vacuum cleaner. When inserting the Staubabscheideisme 4, the collar 21 is first inserted into the recess 22 on the front side 23 of the vacuum cleaner 1.
- the Staubabscheidetician 4 is so located only in the region of the vacuum cleaner fan seal 12, the front of the Vacuum cleaner 1 is closest to the vacuum cleaner fan seal 12 at.
- the Staubabscheidetician 4 is inserted in a lever movement in the vacuum cleaner 1, so that the collar 21 engages in the recess 22 on the rear side 24 of the vacuum cleaner 1. Thereafter, the entire sealing surface of the vacuum cleaner fan seal 12 is applied to the Staubabscheidetician 4, so that an optimal sealing effect can be achieved.
- the collar 21 on the Staubabscheidetician 4 and the recess 22 on the vacuum cleaner 1 ensure that the Staubabscheidetician 4 is precisely positioned in the vacuum cleaner 1, so that the vacuum cleaner fan seal 12 is charged in the right way and no leakage occurs.
- the conical taper 16 around the outlet opening 7 of the Staubabscheidetician 4 serves at the same time when inserting the Staubabscheidetician 4 as centering, so that a more accurate positioning of Staubabscheidetician 4 is possible.

Die der Erfindung zugrundeliegende Aufgabe wird gelöst durch einen Staubsauger mit einer Staubsaugergebläsedichtung gemäß Anspruch 1.The object underlying the invention is achieved by a vacuum cleaner with a vacuum cleaner fan seal according to claim 1.
Eine Staubsaugergebläsedichtung ist eine Dichtung, die dazu geeignet ist, in einen Staubsauger eingesetzt zu werden und dort das Gebläse gegenüber einem an das Gebläse angrenzenden Teil, wie z. B. eine Filterkammer oder einen Staubabscheideraum, abzudichten. Ein Ring ist ein Körper, der durch einen Tunnel vollständig durchstoßen wird. Der erfindungsgemäße Ring ist vorzugsweise rotationssymmetrisch, zum Beispiel ein Torus. Bevorzugt ist der Ring die Rotationsfigur eines Vierecks, besonders bevorzugt eines Rechtecks und ganz besonders bevorzugt eines Quadrats. Erfindungsgemäß ist ein innerer Ring von einem äußeren Ring umgeben. Zwischen dem inneren und dem äußeren Ring ist eine im Wesentlichen geschlossene Membran aufgespannt. Die Ringe dienen zur Definition der Membran. Dies bedeutet, dass die Ringe nicht notwendigerweise von der Membran unterscheidbar sind. Vorzugsweise sind jedoch der innere und/oder äußere Ring von der Membran unterscheidbar. Besonders vorzugsweise weisen der innere und/oder äußere Ring eine verstärkende Funktion auf. Eine Oberflächenlinie ist eine Linie auf der Oberfläche der Membran, die den Punkt an dem die Membran dem äußeren Ring entspringt mit dem nächstgelegenen Punkt, an dem die Membran in den inneren Ring übergeht, verbindet. Dabei verläuft die Oberflächenlinie entlang der Oberfläche der Membran. Erfindungsgemäß ist die Membran abschnittsweise gewölbt, dies bedeutet, dass mindestens eine der genannten Oberflächenlinien nicht der kürzesten Verbindung zwischen den beiden genannten Punkten entspricht. Vorzugsweise ist die gesamte Membran gewölbt, das heißt, dass keine Oberflächenlinie der kürzesten Verbindung der genannten zwei Punkte entspricht.A vacuum cleaner blower seal is a seal that is adapted to be inserted into a vacuum cleaner and there the blower to a fan adjacent to the part, such as. B. a filter chamber or a Staubabscheideraum to seal. A ring is a body that is completely pierced by a tunnel. The ring according to the invention is preferably rotationally symmetrical, for example a torus. Preferably, the ring is the rotation figure of a quadrangle, more preferably a rectangle, and most preferably a square. According to the invention, an inner ring is surrounded by an outer ring. Between the inner and the outer ring, a substantially closed membrane is clamped. The rings are used for Definition of the membrane. This means that the rings are not necessarily distinguishable from the membrane. Preferably, however, the inner and / or outer ring are distinguishable from the membrane. Particularly preferably, the inner and / or outer ring have a reinforcing function. A surface line is a line on the surface of the membrane which connects the point at which the membrane originates from the outer ring to the closest point at which the membrane merges into the inner ring. The surface line runs along the surface of the membrane. According to the invention the membrane is curved in sections, this means that at least one of said surface lines does not correspond to the shortest connection between the two mentioned points. Preferably, the entire membrane is curved, that is, no surface line corresponds to the shortest connection of said two points.
Durch die erfindungsgemäße Staubsaugergebläsedichtung ist es möglich, ein Staubsaugergebläse besonders gut abdichtend mit einer Staubabscheideeinheit zu verbinden. Insbesondere ist es mit der erfindungsgemäßen Staubsaugergebläsedichtung möglich, einen Staubsauger mit einer geringen Gebläseleistung zwischen Gebläse und Staubabscheideeinheit abzudichten. Die erfindungsgemäße Staubsaugergebläsedichtung ist besonders geeignet für einen akkubetriebenen Staubsauger, da gerade in diesem nur eine eingeschränkte Gebläseleistung zur Verfügung steht. Zudem weist die erfindungsgemäße Staubsaugergebläsedichtung den Vorteil auf, dass bei einem Staubsauger mit einer herausnehmbaren Staubabscheideeinheit der Übergang zwischen Staubabscheideeinheit und Gebläse besonders gut abgedichtet werden kann. Die erfindungsgemäße Staubsaugergebläsedichtung ist in der Lage, unterschiedliche Spaltbreiten zwischen Staubabscheideeinheit und Gebläse zu überbrücken. Dies bedeutet, dass die Staubsaugergebläsedichtung variierende Spaltbreiten, die durch das unpräzise Einsetzen der Staubabscheideeinheit in den Staubsauger entstehen, problemlos ausgleichen kann. Zudem können die Bauteile des Staubsaugers mit einer größeren Toleranz gefertigt werden, da auch die Toleranzen in den Bauteilabmessungen durch die Staubsaugergebläsedichtung ausgeglichen werden können. Wenn die Ringe verstärkende Wirkung zeigen, so kann die erfindungsgemäße Staubsaugergebläsedichtung mit Vorteil den häufigen Ein- und Ausbau der Staubabscheideeinheit erlauben, ohne dass die Staubsaugergebläsedichtung beschädigt oder zerstört wird. Bei zugleich hoher Dichtwirkung der erfindungsgemäßen Staubsaugergebläsedichtung ermöglicht es diese zugleich, die Staubabscheideeinheit leicht zu entnehmen, da die Staubsaugergebläsedichtung ihre Dichtwirkung schon bei geringer Fügekraft entfaltet.By the vacuum cleaner fan gasket according to the invention, it is possible to connect a vacuum cleaner fan particularly good sealing with a Staubabscheideeinheit. In particular, it is possible with the vacuum cleaner fan seal according to the invention to seal a vacuum cleaner with a low blower power between blower and Staubabscheideeinheit. The vacuum cleaner fan gasket according to the invention is particularly suitable for a battery-operated vacuum cleaner, since just in this only a limited fan power is available. In addition, the vacuum cleaner fan seal according to the invention has the advantage that in a vacuum cleaner with a removable Staubabscheideeinheit the transition between Staubabscheideeinheit and blower can be particularly well sealed. The vacuum cleaner fan gasket according to the invention is able to bridge different gap widths between Staubabscheideeinheit and blower. This means that the vacuum cleaner fan seal can easily compensate for varying gap widths that result from the imprecise insertion of the Staubabscheideeinheit in the vacuum cleaner. In addition, the components of the vacuum cleaner can be made with a greater tolerance, since the tolerances in the component dimensions can be compensated by the vacuum cleaner fan seal. If the rings have a reinforcing effect, the vacuum cleaner fan gasket according to the invention can advantageously permit frequent installation and removal of the dust removal unit without damaging or destroying the vacuum cleaner fan gasket. At the same time high sealing effect of the invention Vacuum cleaner fan seal allows this at the same time to easily remove the Staubabscheideeinheit because the vacuum cleaner fan seal unfolds their sealing effect even at low joining force.
Der erfindungsgemäße Staubsauger weist eine entnehmbare Staubabscheideeinheit auf. Eine solche Staubabscheideeinheit kann einen Filter und/oder einen Wirbelabscheider enthalten, in dem der Staub von der Saugluft durch Zentrifugalkräfte abgetrennt wird. Die Entleerung der entnehmbaren Staubabscheideeinheit gestaltet sich besonders einfach, da die Staubabscheideeinheit leicht zu einem Sammelbehälter für Hausmüll transportiert werden kann. Die erfindungsgemäße Staubsaugergebläsedichtung ist besonders gut für die Verwendung in Verbindung mit einer entnehmbaren Staubabscheideeinheit geeignet, da die radialen Kräfte, die beim Einsetzen der Staubabscheideeinheit wirken können, diese Staubsaugergebläsedichtung nur wenig beanspruchen. Zugleich kann die erfindungsgemäße Staubsaugergebläsedichtung ein ungenaues Einsetzen der Staubabscheideeinheit dadurch ausgleichen, dass sie sich besonders gut an die Staubabscheideeinheit anschmiegen kann.The vacuum cleaner according to the invention has a removable Staubabscheideeinheit. Such Staubabscheideeinheit may include a filter and / or a Wirbelabscheider in which the dust is separated from the suction air by centrifugal forces. The emptying of the removable Staubabscheideeinheit designed particularly simple, since the Staubabscheideeinheit can be easily transported to a collection container for household waste. The vacuum cleaner fan gasket according to the invention is particularly well suited for use in conjunction with a removable dust collecting unit, since the radial forces that can act on insertion of the dust collecting unit only make little use of this vacuum cleaner fan gasket. At the same time, the vacuum cleaner fan gasket according to the invention can compensate for an inaccurate insertion of the Staubabscheideeinheit thereby, that they can cling particularly well to the Staubabscheideeinheit.
Vorzugsweise ist die Membran so gewölbt, dass sie auf der Gebläseseite konkav ist. Es ist jedoch auch möglich, dass die Membran auf der Gebläseseite konvex ausgeformt ist. Die Membran ist vorzugsweise so gestaltet, dass mindestens eine, besonders vorzugsweise alle Oberflächenlinien eine monoton fallende Steigung haben. Es ist ebenfalls möglich, dass mindestens eine, vorzugsweise alle Oberflächenlinien monoton ansteigen. Die Staubsaugergebläsedichtung wird vorzugsweise aus einem elastischen Material, z. B. einem Elastomer, hergestellt. So kann eine besonders hohe Dichtungswirkung erzeugt werden.Preferably, the membrane is curved so that it is concave on the fan side. However, it is also possible that the membrane is convexly formed on the fan side. The membrane is preferably designed so that at least one, more preferably all surface lines have a monotonically decreasing pitch. It is also possible that at least one, preferably all surface lines increase monotonically. The vacuum cleaner fan seal is preferably made of an elastic material, e.g. As an elastomer produced.

Dies bedeutet, dass die Membran dünner ist als der Ring an seiner dicksten Stelle. Bevorzugt ist die Membran dünner als der Ring an seiner dünnsten Stelle. Wenn der Ring eine Rotationsfigur darstellt, so ist bevorzugt, dass die Membran dünner ist als der größte Durchmesser der Figur, auf der die Rotationsfigur basiert. Besonders bevorzugt ist die Membran dünner als der kleinste Durchmesser dieser Figur. An dem dickeren inneren Ring kann die Staubsaugergebläsedichtung besonders gut an einem Staubsaugergebläse fixiert werden. Die dünnere Membran kann sich auch bei geringen Unterdrücken, z. B. in einem akkubetriebenen Staubsauger, gut an die Staubabscheideeinheit anschmiegen und so eine hohe Dichtwirkung erzeugen.In a particular embodiment of the vacuum cleaner fan gasket according to the invention, the membrane is thinner than the inner ring. This means that the membrane is thinner than the ring at its thickest point. Preferably, the membrane is thinner than the ring at its thinnest point. When the ring is a rotational figure, it is preferred that the membrane be thinner than the largest diameter of the figure on which the rotational figure is based. Particularly preferably, the membrane is thinner than the smallest diameter of this figure. On the thicker inner ring, the vacuum cleaner fan seal can be fixed very well on a vacuum cleaner fan. The thinner membrane can also be at low negative pressures, z. B. in a battery-powered vacuum cleaner, nestle well on the Staubabscheideeinheit and so produce a high sealing effect.
Erfindungsgemäß ist es bevorzugt, dass die Membran dünner ist als der äußere Ring. Dies bedeutet, dass die Membran dünner als der äußere Ring an seiner dicksten Stelle ist. Vorzugsweise ist die Membran dünner als der äußere Ring an seiner dünnsten Stelle. Wenn der äußere Ring eine Rotationsfigur ist, so ist es bevorzugt, dass die Figur, auf der die Rotationsfigur basiert, einen größten Durchmesser, besonders bevorzugt einen kleinsten Durchmesser, aufweist, der größer ist als die Dicke der Membran. Durch den dicken äußeren Ring kann der Staubsaugergebläsedichtung nach außen hin eine hohe Stabilität verliehen werden. Insbesondere kann so ein Einknicken der Membran verhindert werden, wenn die Staubabscheideeinheit in den Staubsauger eingesetzt wird. Alternativ kann der innere und/oder äußere Ring auch genauso dick oder dünner als die Membran sein. Dies kann zur Folge haben, dass der innere und/oder äußere Ring von der Membran nicht unterscheidbar sind.According to the invention it is preferred that the membrane is thinner than the outer ring. This means that the membrane is thinner than the outer ring at its thickest point. Preferably, the membrane is thinner than the outer ring at its thinnest point. When the outer ring is a rotational figure, it is preferable that the figure on which the rotational figure is based has a largest diameter, more preferably a smallest diameter, larger than the thickness of the membrane. Due to the thick outer ring, the vacuum cleaner fan seal can be imparted outwards a high stability. In particular, such a buckling of the membrane can be prevented when the Staubabscheideeinheit is inserted into the vacuum cleaner. Alternatively, the inner and / or outer ring may also be as thick or thinner than the membrane. This can result in the inner and / or outer ring being indistinguishable from the membrane.
Die Staubsaugergebläsedichtung kann z. B. so gestaltet sein, dass sie mit dem inneren Ring an einem Staubsauger befestigt ist und zugleich der äußere Ring an einem Teil des Staubsaugers anliegt oder keinem Teil des Staubsaugers anliegt, sondern zum nächsten Teil des Staubsaugers beabstandet ist. Durch das Auflegen des äußeren Rands am Staubsauger kann eine besondere Stabilität der Staubsaugergebläsedichtung, insbesondere beim Einsetzen der Staubabscheideeinheit, erreicht werden. Durch die Beabstandung kann eine besondere Flexibilität der Staubsaugergebläsedichtung erreicht werden, wobei der dickere äußere Rand weiterhin der Membran eine gute Stabilität verleiht. Die Beabstandung ermöglicht es ferner, dass die Staubsaugergebläsedichtung sich frei verformen lässt und so die Staubabscheideeinheit leicht einzusetzen ist, wobei die Verformbarkeit der Staubsaugergebläsedichtung Fertigungstoleranzen der Staubabscheideeinheit und des Gebläses sowie Ungenauigkeiten bei der Positionierung der beiden zueinander nach dem Einsetzen durch den Benutzer ausgleichen kann.The vacuum cleaner fan seal may, for. B. be designed so that it is attached to the inner ring to a vacuum cleaner and at the same time the outer ring rests against a part of the vacuum cleaner or no part of the vacuum cleaner is applied, but to the next Part of the vacuum cleaner is spaced. By placing the outer edge on the vacuum cleaner, a particular stability of the vacuum cleaner fan seal, in particular when inserting the Staubabscheideeinheit be achieved. By the spacing, a particular flexibility of the vacuum cleaner fan seal can be achieved, wherein the thicker outer edge continues to give the membrane good stability. The spacing also allows the vacuum cleaner fan seal to freely deform, thus making the dust extractor unit easy to use, with the ductility of the vacuum cleaner fan gasket capable of compensating for manufacturing tolerances of the dust extractor and blower and inaccuracies in positioning the two together after insertion by the user.
Es ist bevorzugt, dass die Dicke der Membran der erfindungsgemäßen Staubsaugergebläsedichtung in radialer Staubsaugergebläsedichtung abnimmt. Dies bedeutet, dass die Dicke der Membran am Übergang zum inneren Ring größer ist als die Dicke der Membran am Übergang zum äußeren Ring. Vorzugsweise nimmt die Dicke der Staubsaugergebläsedichtung vom inneren zum äußeren Ring hin monoton ab. So kann gewährleistet werden, dass in der Nähe des inneren Rings eine hohe Stabilität der Staubsaugergebläsedichtung gegeben ist und die Staubsaugergebläsedichtung auch ein häufiges Einsetzen der Staubabscheideeinheit unbeschadet überstehen kann. Zudem führt die geringe Dicke der Membran in der Nähe des äußeren Rings dazu, dass sich die Membran dort besonders einfach verformen kann und - insbesondere bei eingeschaltetem Gebläse und dadurch entstehendem Unterdruck - dem Gebläse gut anschmiegen kann.It is preferred that the thickness of the membrane of the vacuum cleaner fan seal according to the invention decreases in the radial vacuum cleaner fan seal. This means that the thickness of the membrane at the transition to the inner ring is greater than the thickness of the membrane at the transition to the outer ring. Preferably, the thickness of the vacuum cleaner fan seal decreases monotonically from the inner to the outer ring. Thus, it can be ensured that in the vicinity of the inner ring, a high stability of the vacuum cleaner fan seal is given and the vacuum cleaner fan seal can withstand a frequent insertion of Staubabscheideeinheit unscathed. In addition, the small thickness of the membrane in the vicinity of the outer ring to the fact that the membrane can deform very easily there and - especially when the fan is switched on and resulting negative pressure - the blower can nestle well.
Erfindungsgemäß ist es bevorzugt, dass die Staubsaugergebläsedichtung rotationssymmetrisch ist. Durch die Rotationssymmetrie kann die Kraft, die einerseits durch den Unterdruck des Gebläses und andererseits durch das Einsetzen und Herausnehmen der Staubabscheideeinheit auf die Staubsaugergebläsedichtung übertragen wird, gleichmäßig verteilt werden. So kann vermieden werden, dass sich einzelne Bereiche der Staubsaugergebläsedichtung besonders schnell abnutzen und die Staubsaugergebläsedichtung schon nach kurzer Benutzung zerstört wird.According to the invention it is preferred that the vacuum cleaner fan seal is rotationally symmetrical. Due to the rotational symmetry, the force, which is transmitted on the one hand by the negative pressure of the blower and on the other hand by the insertion and removal of Staubabscheideeinheit on the vacuum cleaner fan seal, can be evenly distributed. So it can be avoided that some areas of the vacuum cleaner fan seal wear out very quickly and the vacuum cleaner fan seal is destroyed after only a short use.
Erfindungsgemäß ist es bevorzugt, dass der innere Ring sich in einem Rohr fortsetzt. So kann die Staubsaugergebläsedichtung besonders gut an einer Einlassöffnung des Staubsaugergebläses befestigt werden. Durch die Befestigung an dem Rohr erfährt die Staubsaugergebläsedichtung sowohl in axialer als auch radialer Richtung bezogen auf das Rohr eine Befestigung, was insbesondere bei der erfindungsgemäßen Staubsaugergebläsedichtung, die sowohl durch den Unterdruck des Gebläses als auch durch das wiederholte Einsetzen der Staubabscheideeinheit beansprucht wird, vorteilhaft ist.According to the invention it is preferred that the inner ring continues in a tube. Thus, the vacuum cleaner fan seal particularly well at an inlet opening of the Vacuum cleaner fan to be attached. By attachment to the pipe, the vacuum cleaner fan seal undergoes attachment in both the axial and radial directions with respect to the pipe, which is particularly advantageous in the vacuum cleaner fan seal of the present invention, which is claimed by both the negative pressure of the blower and repeated insertion of the dust separation unit ,
Es ist erfindungsgemäß bevorzugt, dass die Staubsaugergebläsedichtung einen Kragen aufweist. Vorzugsweise befindet sich der Kragen näher an dem inneren Ring als an dem äußeren Ring. Es ist bevorzugt, dass sich der Kragen an dem Rohr befindet, in das sich der innere Ring fortsetzt. Besonders bevorzugt ist der Kragen an der äußeren Oberfläche des Rohres befestigt. Durch den Kragen kann die Staubsaugergebläsedichtung besonders einfach an einem Staubsauger befestigt werden.It is inventively preferred that the vacuum cleaner fan seal has a collar. Preferably, the collar is closer to the inner ring than to the outer ring. It is preferred that the collar is on the tube into which the inner ring continues. Particularly preferably, the collar is attached to the outer surface of the tube. Thanks to the collar, the vacuum cleaner fan seal can be attached to a vacuum cleaner in a particularly easy way.
In einer bevorzugten Ausführungsform weist der erfindungsgemäße Staubsauger eine Nut auf, in die der Kragen der Staubsaugergebläsedichtung einrasten kann. Die Befestigung der Staubsaugergebläsedichtung in der Nut ist im Herstellungsprozess besonders einfach. Zugleich wird die Staubsaugergebläsedichtung besonders belastbar in der Nut fixiert.In a preferred embodiment, the vacuum cleaner according to the invention has a groove into which the collar of the vacuum cleaner fan seal can engage. The attachment of the vacuum cleaner fan seal in the groove is particularly easy in the manufacturing process. At the same time the vacuum cleaner fan seal is fixed particularly strong in the groove.
Es ist bevorzugt, dass die Staubabscheideeinheit sich auf der dem Gebläse zugewandten Seite verjüngt. An der Seite der Staubabscheideeinheit, an der sich eine Öffnung befindet, durch die die Luft ins Gebläse gelangen kann, verjüngt sich die bevorzugte Staubabscheideeinheit. Besonders vorzugsweise läuft die Wand, die die Öffnung umgibt, aus der die Luft in das Gebläse einströmen kann, konisch zu. So kann erreicht werden, dass sich die Staubsaugergebläsedichtung besonders gut an die Staubabscheideeinheit anschmiegen kann.It is preferred that the Staubabscheideeinheit tapers on the fan-facing side. At the side of the Staubabscheideeinheit, at which there is an opening through which the air can enter the fan, the preferred Staubabscheideeinheit tapers. Particularly preferably, the wall surrounding the opening, from which the air can flow into the fan, tapers conically. Thus, it can be achieved that the vacuum cleaner fan seal can cling particularly well to the Staubabscheideeinheit.
Erfindungsgemäß ist es besonders bevorzugt, dass an dem Staubsauger und/oder der Staubabscheideeinheit Merkmale angebracht sind, durch die ein Einführungsweg definiert wird, sodass die Staubabscheideeinheit zunächst schräg zur Ebene der Staubsaugergebläsedichtung auf der Staubsaugergebläsedichtung aufliegt. Die bevorzugte Staubabscheideeinheit weist dazu eine Rippe, besonders vorzugsweise eine umlaufende Rippe auf. Der bevorzugte Staubsauger enthält eine Vertiefung, in die diese Rippe eingeführt werden kann. In einer Ausführungsform kann nach Einsetzen der Rippe in die Vertiefung die Staubabscheideeinheit in einer Hebelbewegung, das heißt in einer Rotation um die die Achse der Vertiefung, in den Staubsauger eingesetzt werden. Dabei berührt die Staubabscheideeinheit die Staubsaugergebläsedichtung zunächst an der der Vertiefung zugewandten Seite. Durch die Hebelbewegung werden fortlaufend auch die weiter von der Vertiefung entfernten Teile der Staubabscheideeinheit an die Staubsaugergebläsedichtung angefügt, sodass zuletzt die gesamte Dichtfläche der Staubsaugergebläsedichtung mit der gewünschten Fügekraft gegen die Staubabscheideeinheit gepresst wird. Die erfindungsgemäße Staubsaugergebläsedichtung ist besonders gut für die zunächst beim Einsetzen einseitige Krafteinwirkung geeignet, da die Staubsaugergebläsedichtung sowohl durch den inneren als auch den äußeren Ring stabilisiert wird. Durch den definierten Einführungsweg kann ein präzises Einführen der Staubabscheideeinheit in den Staubsauger erreicht werden.According to the invention it is particularly preferred that features are attached to the vacuum cleaner and / or the Staubabscheideeinheit through which an introduction path is defined, so that the Staubabscheideeinheit initially rests obliquely to the plane of the vacuum cleaner fan seal on the vacuum cleaner fan seal. The preferred Staubabscheideeinheit has for this purpose a rib, particularly preferably a circumferential rib. The preferred vacuum cleaner includes a recess into which these Rib can be introduced. In one embodiment, after inserting the rib into the recess, the dust collecting unit can be inserted into the vacuum cleaner in a lever movement, that is to say in a rotation about the axis of the depression. The Staubabscheideeinheit first touches the vacuum cleaner fan seal on the side facing the recess. As a result of the lever movement, the parts of the dust removal unit which are further removed from the depression are also continuously added to the vacuum cleaner fan seal, so that the entire sealing surface of the vacuum cleaner fan seal is pressed against the dust separation unit with the desired joining force. The vacuum cleaner fan seal according to the invention is particularly well suited for the one-sided application of force at first, since the vacuum cleaner fan seal is stabilized by both the inner and the outer ring. By the defined introduction path, a precise insertion of Staubabscheideeinheit be achieved in the vacuum cleaner.
Die Erfindung ermöglicht es, eine Staubsaugergebläsedichtung herzustellen, die bei bereits sehr geringer Fügekraft und bei geringen Drücken eine sehr gute Dichtwirkung aufweist. Dies ist insbesondere von Vorteil bei Staubsaugern mit einer geringen Gebläseleistung, wie es z. B. bei akkubetriebenen Staubsaugern gewöhnlich der Fall ist. Zudem ist die erfindungsgemäße Staubsaugergebläsedichtung so gestaltet, dass beim Fügen der Staubsaugergebläsedichtung nur sehr wenig Reibung auf der Staubsaugergebläsedichtung auftritt, sodass die Staubsaugergebläsedichtung nur eine geringe Abnutzung erfährt und besonders lange verwendet werden kann. Zudem wird durch die Membran der Staubsaugergebläsedichtung eine hohe Toleranzbreite erreicht. Dies bedeutet, dass höhere Fertigungstoleranzen der Staubsaugerteile nicht zu einem Verlust der Dichtwirkung führen. Zusätzlich wird durch ein unpräzises Einsetzen der Staubabscheideeinheit in den Staubsauger die Abdichtung nicht verringert.The invention makes it possible to produce a vacuum cleaner fan seal, which has a very good sealing effect at already very low joining force and at low pressures. This is particularly advantageous in vacuum cleaners with a low blower power, as z. B. is usually the case with battery-operated vacuum cleaners. In addition, the vacuum cleaner fan seal according to the invention is designed so that when joining the vacuum cleaner fan seal very little friction on the vacuum cleaner fan seal occurs, so that the vacuum cleaner fan seal undergoes little wear and can be used for a particularly long time. In addition, a high tolerance width is achieved by the membrane of the vacuum cleaner fan seal. This means that higher manufacturing tolerances of the vacuum cleaner parts do not lead to a loss of sealing effect. In addition, the sealing is not reduced by an imprecise insertion of Staubabscheideeinheit in the vacuum cleaner.
