Description

Die Erfindung betrifft einen Staubsauger, insbesondere einen Bodenstaubsauger, nach dem Oberbegriff des Anspruchs 1. Bekannt sind weiterhin unterschiedliche Ansätze für die Halterung oder Lagerung des Staubsaugergebläses in einem vom Staubsauger umfassten Gebläseraum. Zur Vermeidung unerwünschter Geräuschentwicklung kommt eine elastische Lagerung z.B. unter Verwendung von Gummipuffern und dergleichen in Betracht.The invention relates to a vacuum cleaner, in particular a vacuum cleaner, according to the preamble of claim 1. Also known are different approaches for the support or storage of the vacuum cleaner fan in a fan chamber included by the vacuum cleaner. To avoid unwanted noise, elastic storage occurs e.g. using rubber buffers and the like.

Bei besonders hochwertigen Staubsaugern ist die Verwendung einer das Staubsaugergebläse umgebenden Dämmkapsel vorgesehen. Bei einer Lagerung eines derart gekapselten Staubsaugergebläses erfolgt diese durch Verwendung von auf die Dämmkapsel abgestimmten Lagerelementen. Bei Verzicht auf die Dämmkapsel kommen demgegenüber Lagerelemente zum Einsatz, die auf das Staubsaugergebläse abgestimmt sind.For particularly high-quality vacuum cleaners, the use of an insulating capsule surrounding the vacuum cleaner fan is provided. When storing such an encapsulated vacuum cleaner fan this is done by using matched to the Dämmkapsel bearing elements. By dispensing with the Dämmkapsel come in contrast bearing elements are used, which are tailored to the vacuum cleaner fan.

Ein Staubsauger den mit Merkmalen des Oberbegriffs des Anspruchs 1 ist aus der JP 64 004366 U bekannt. Eine Aufgabe der Erfindung besteht entsprechend darin, die Anzahl der für eine Herstellung eines Staubsaugers erforderlichen Einzelteile zu reduzieren.A vacuum cleaner having features of the preamble of claim 1 is known from JP 64 004366 U known. Accordingly, it is an object of the invention to reduce the number of items required to produce a vacuum cleaner.

Diese Aufgabe wird für einen Staubsauger mit einem in einem Gebläseraum angeordneten Staubsaugergebläse mit den Merkmalen des Anspruchs 1 gelöst, indem das Staubsaugergebläse ausschließlich mit mindestens zwei Lagerelementen, nämlich jeweils mindestens einem front- und rückseitigem Lagerelement, in dem Gebläseraum gehalten wird, wobei die Lagerelemente eine Halterung des Staubsaugergebläses mit und ohne eine das Staubsaugergebläse umgebende Dämmkapsel erlauben. Die Erfindung erlaubt also die Verwendung gleicher Lagerelemente (Gleichteile) für die Halterung des Staubsaugergebläses unabhängig davon, ob dieses von einer Dämmkapsel umgeben ist oder nicht. Die Anzahl der für die Herstellung des Staubsaugers erforderlichen Einzelteile reduziert sich damit, weil bei beiden in Bezug auf die Montage des Staubsaugergebläses in Betracht kommenden Varianten gleiche Lagerelemente verwendbar sind. Der Vorteil besteht in den reduzierten Lagerhaltungskosten, weil nur noch eine Variante von Lagerelementen erforderlich ist. Zudem werden Konstruktionskosten eingespart durch die Vermeidung derjenigen Kosten, die bisher für die Entwicklung von unterschiedlichen Lagerelementen für beide Einbauvarianten erforderlich waren. Des Weiteren werden, nachdem es sich bei solchen Lagerelementen im Wesentlichen um Formteile handelt, Kosten für die Erstellung und den Erhalt solcher Formen eingespart. Im Ergebnis erlaubt die Erfindung eine Kosten- und Materialeinsparung und führt zu einer Fertigungsvereinfachung.This object is achieved for a vacuum cleaner with a arranged in a fan room vacuum cleaner fan with the features of claim 1 by the vacuum cleaner fan exclusively with at least two bearing elements, namely in each case at least one front and back bearing element is held in the fan chamber, wherein the bearing elements a Allow mounting of the vacuum cleaner fan with and without an insulating capsule surrounding the vacuum cleaner fan. The invention thus allows the use of the same bearing elements (identical parts) for holding the vacuum cleaner fan regardless of whether this is surrounded by a Dämmkapsel or not. The number of items required for the production of the vacuum cleaner is thus reduced, because in both with respect to the assembly of the vacuum cleaner fan suitable variants bearing elements are used. The advantage is the reduced storage costs, because only one variant of bearing elements is required. In addition, construction costs are saved by avoiding those costs that were previously required for the development of different storage elements for both installation variants. Furthermore, after such bearing elements are essentially molded parts, the cost of creating and maintaining such shapes is saved. As a result, the invention allows cost and material savings and leads to a manufacturing simplification.

Eine Gebläseeinheit für einen Staubsauger, die hier und nachfolgend als Staubsaugergebläse bezeichnet ist, besteht aus einem elektrischen Antriebsmotor (Motor) mit einem Lagertopf zur Aufnahme der Baumodule des Motors sowie aus einer vom Motor angetriebenen, mindestens einstufigen Gebläseeinheit mit einem Laufrad und einer Ansaughaube und eventuell einer zwischen Laufrad und Motor befindlichen Leitstufe. Das Staubsaugergebläse ist eventuell von einer Dämmkapsel umgeben. Bei der Bezeichnung einzelner Lagerelemente als front- oder rückseitig bezieht sich dies nicht auf die Einbausituation und die damit einhergehende Ausrichtung des Staubsaugergebläses im Gebläseraum. Frontseitig meint stattdessen stets die Saugseite der Gebläseeinheit und rückseitig meint entsprechend die gegenüberliegende Seite des Staubsaugergebläses.A blower unit for a vacuum cleaner, here and hereinafter referred to as a vacuum cleaner fan, consists of an electric drive motor (motor) with a bearing cup for receiving the building modules of the engine and from a motor driven, at least one-stage blower unit with an impeller and a suction hood and possibly a control stage located between the impeller and the engine. The vacuum cleaner fan may be surrounded by an insulating capsule. In the designation of individual bearing elements as front or rear side, this does not refer to the installation situation and the concomitant orientation of the vacuum cleaner fan in the fan room. Instead, the front side always means the suction side of the blower unit and the rear accordingly means the opposite side of the vacuum cleaner blower.

Wenn der Lagerring eine Mehrzahl von Ausnehmungen aufweist, die über den Außenumfang verteilt, insbesondere gleichmäßig verteilt, und von der Außenumfangsfläche zurückgesetzt sind, stehen die Außenumfangsfläche zur Kontaktierung durch das Halteelement, also zur Lagerung des Staubsaugergebläses, und einzelne oder mehrere von der Außenumfangsfläche zurückgesetzte Ausnehmungen zur Lagerung der Dämmkapsel zur Verfügung.If the bearing ring has a plurality of recesses which are distributed over the outer circumference, in particular evenly distributed, and reset from the outer peripheral surface, the outer peripheral surface for contacting by the holding element, so for storage of the vacuum cleaner fan, and one or more recessed from the outer peripheral surface recesses for storage of the insulating capsule available.

Die abhängigen Ansprüche sind auf besondere Ausführungsformen der vorliegenden Erfindung gerichtet. Dabei verwendete Rückbeziehungen weisen auf die weitere Ausgestaltung des Gegenstands des Hauptanspruchs durch die Merkmale des jeweiligen Unteranspruchs hin. Sie können auch selbständige Erfindungen enthalten, die eine von den Gegenständen der vorhergehenden Ansprüche unabhängige Gestaltung aufweisen und sind nicht als ein Verzicht auf die Erzielung eines selbständigen, gegenständlichen Schutzes für deren Merkmale zu verstehen. Des Weiteren ist im Hinblick auf eine Auslegung der Ansprüche bei einer näheren Konkretisierung eines Merkmals in einem nachgeordneten Anspruch davon auszugehen, dass eine derartige Beschränkung in den jeweils vorangehenden Ansprüchen nicht vorhanden ist.The dependent claims are directed to particular embodiments of the present invention. Relationships used here point to the further embodiment of the subject matter of the main claim by the features of the respective subclaim. They may also contain independent inventions having a design independent of the objects of the preceding claims and are not to be understood as a waiver of obtaining independent, objective protection of their characteristics. Furthermore, with a view to an interpretation of the claims in a closer specification of a feature in a subordinate claim, it is to be assumed that such a restriction does not exist in the respective preceding claims.

Die Dämmkapsel ist an einem mit Ausnehmungen versehenen Lagerring besonders einfach anbringbar, wenn diese oder ein Teil einer solchen Dämmkapsel im Bereich einer Dämmkapselgebläseöffnung eine Mehrzahl von Lagerringkontaktelementen aufweist, die nach Größe und untereinander bestehendem Abstand zur Anbringung der Dämmkapsel bzw. des Dämmkapselteils an der Ansaughaube jeweils in eine der Ausnehmungen entlang der Außenumfangsfläche des Lagerrings einführbar sind.The Dämmkapsel is particularly easy to attach to a provided with recesses bearing ring, if this or a part of such Dämmkapsel in the region of Dämmkapselgebläseöffnung a plurality of bearing ring contact elements, the size and each existing distance for attaching the Dämmkapsel or the Dämmkapselteils to the suction hood respectively in one of the recesses along the outer peripheral surface of the bearing ring are insertable.

In einer speziellen Ausführungsform sind die mindestens zwei Lagerelemente nicht nur zu einer vom Gebläseraum mechanisch entkoppelten Lagerung des Staubsaugergebläses, sondern gleichzeitig auch zu einer sowohl vom Gebläseraum wie auch vom Staubsaugergebläse mechanisch entkoppelten Lagerung der Dämmkapsel wirksam. Die Lagerelemente halten also gleichzeitig das Staubsaugergebläse und die Dämmkapsel und zwar so, dass auch Staubsaugergebläse und Dämmkapsel voneinander mechanisch entkoppelt sind. Quellen für eine potentielle zusätzliche Geräuschentwicklung werden auf diese Weise von Anfang an eliminiert.In a special embodiment, the at least two bearing elements are effective not only for a mechanically decoupled from the fan room storage of the vacuum cleaner fan, but at the same time to a both the fan room as well as the vacuum cleaner fan mechanically decoupled storage of Dämmkapsel effective. The So storage elements hold at the same time the vacuum cleaner fan and the Dämmkapsel in such a way that even vacuum cleaner fan and Dämmkapsel are mechanically decoupled from each other. Sources of potential additional noise are eliminated in this way from the beginning.

Wenn das Staubsaugergebläse eine Gebläseeinheit mit einer Ansaughaube und einer darin freibleibenden Ansaugöffnung aufweist, ist bei einer Ausführungsform der Erfindung vorgesehen, dass ein Lagerring mit einer in dessen Zentrum freibleibenden und zur Ansaugöffnung passenden Lagerringöffnung als das mindestens eine frontseitige Lagerelement fungiert. Der Lagerring ist dann direkt an der Ansaughaube anbringbar. Wenn die Ansaughaube eine die Ansaugöffnung umlaufende Wulst aufweist, besteht eine Ausführungsform des Lagerrings darin, dass dieser auf die Wulst aufsetzbar ist und dort im aufgesetzten Zustand im Passsitz gehalten wird. Das Anbringen des Lagerrings an der Ansaughaube vereinfacht sich bei dieser Ausführungsform also zu einem Aufsetzen auf die dort gebildete Wulst.When the vacuum cleaner blower has a blower unit with an intake hood and a suction opening remaining free therein, in one embodiment of the invention it is provided that a bearing ring with a bearing ring opening which remains free in its center and which fits the intake opening functions as the at least one front bearing element. The bearing ring can then be attached directly to the suction hood. If the suction hood has a bead that surrounds the suction opening, one embodiment of the bearing ring is that it can be placed on the bead and held there snugly in the mounted state. The attachment of the bearing ring on the suction hood is thus simplified in this embodiment to a touchdown on the bead formed there.

Zur frontseitigen Halterung des Staubsaugergebläses kommt ein Halteelement in Betracht, das auf den Außenumfang des Lagerrings abgestimmt ist und bei eingebautem Staubsaugergehäuse den Lagerring aufnimmt, indem das Halteelement zumindest abschnittsweise den Lagerring entlang dessen Außenumfangsfläche kontaktiert. In einer besonders einfachen Ausführungsform kommt ein im Wesentlichen U-förmig gestaltetes Halteelement in Betracht, in dessen Profil der Lagerring mit einer zumindest im Wesentlichen geradlinigen Bewegung einführbar ist, so dass sich ein besonders einfacher Fertigungsschritt ergibt, der auch ohne Weiteres automatisierbar ist.For front-side mounting of the vacuum cleaner fan is a holding element into consideration, which is tuned to the outer circumference of the bearing ring and with built-in vacuum cleaner housing receives the bearing ring by the holding element at least partially contacted the bearing ring along the outer peripheral surface. In a particularly simple embodiment, a substantially U-shaped retaining element is contemplated, in the profile of the bearing ring with an at least substantially rectilinear movement is inserted, so that there is a particularly simple manufacturing step, which is also readily automatable.

In Ausführungsformen des erfindungsgemäßen Staubsaugers ist vorgesehen, dass zwei Puffer als rückseitige Lagerelemente fungieren. Mit zwei Puffern ist eine drehfeste Lagerung des Staubsaugergebläses möglich.In embodiments of the vacuum cleaner according to the invention it is provided that two buffers act as rear bearing elements. With two buffers a non-rotatable mounting of the vacuum cleaner fan is possible.

In einer Ausführungsform des Staubsaugers weist ein Lagertopf des Staubsaugergebläses in einem rückseitigen Abschnitt, also an einer der Gebläseeinheit gegenüberliegenden Seite, zwei Zapfen zur Aufnahme jeweils eines Puffers auf. Derartige Zapfen ermöglichen das Anbringen des jeweiligen Puffers durch einfaches Aufstecken. Auch dieser Montageschritt zeichnet sich durch eine besondere Einfachheit aus und ist zudem ohne Weiteres automatisierbar. Die Zapfen haben insbesondere radial den gleichen Abstand von einer in Verlängerung der Motorachse verlaufenden Achse.In one embodiment of the vacuum cleaner, a bearing cup of the vacuum cleaner fan in a rear portion, ie on one side opposite the fan unit, two pins for receiving a respective buffer. Such pins allow the attachment of the respective buffer by simply plugging. This assembly step is characterized by a particular simplicity and is also easily automated. The pins have in particular radially the same distance from an axis extending in the extension of the motor axis.

Gemäß einer weiteren Ausführungsform umfasst der Staubsauger ein Trägerelement mit Mitteln einerseits zur Anbringung an einem Gehäuseteil des Staubsaugers, insbesondere in dessen Gebläseraum, und zur Aufnahme der am Lagertopf angebrachten oder anbringbaren Puffer. Das Trägerelement kann vor der Montage des Staubsaugergebläses mit den Puffern kombiniert werden, so dass die Montage des Staubsaugergebläses auf dessen rückwärtiger Seite nur noch die Kombination des Trägerelements mit dem jeweiligen Gehäuseteil des Staubsaugers erfordert. Für manuelle Montagevorgänge handelt es sich erneut um einen äußerst einfachen Verfahrensschritt. Dieser ist auch ohne Weiteres automatisierbar, zumal die Montagerichtung im Wesentlichen geradlinig ist und die Montage geradlinig von oben in den geöffneten Staubsauger und dessen Gebläseraum erfolgen kann.According to a further embodiment, the vacuum cleaner comprises a carrier element with means on the one hand for attachment to a housing part of the vacuum cleaner, in particular in the fan room, and for receiving the attached or attachable to the storage cup Buffer. The support member may be combined with the buffers before assembly of the vacuum cleaner fan, so that the mounting of the vacuum cleaner fan on the rear side only requires the combination of the support member with the respective housing part of the vacuum cleaner. Manual assembly operations are again an extremely simple process step. This can also be easily automated, especially since the mounting direction is substantially rectilinear and the installation can be done in a straight line from above into the open vacuum cleaner and its fan room.

Wenn die Dämmkapsel oder ein Teil einer solchen Dämmkapsel auf einer der Dämmkapselgebläseöffnung gegenüberliegenden Oberfläche zwei Pufferaufnahmeöffnungen aufweist, deren Weite oder Geometrie jeweils auf eine Außenkontur der Puffer abgestellt sind und in die jeweils ein Puffer einführbar ist, ergibt sich eine besonders einfache Möglichkeit zur Anbringung der Dämmkapsel bzw. des Dämmkapselteils am Lagertopf. Eine derartige Anbringung der Dämmkapsel oder des Dämmkapselteils gewährleistet eine vom Staubsaugergebläse mechanisch entkoppelte Lagerung der Dämmkapsel. Dadurch, dass der oder jeder Puffer durch die Pufferaufnahmeöffnungen hindurchragt und nur an seinem über die Pufferaufnahmeöffnung hinausragenden Ende von dem Trägerelement kontaktiert wird, ist die Dämmkapsel auch vom Gebläseraum mechanisch entkoppelt gelagert.If the Dämmkapsel or a part of such Dämmkapsel on one of Dämmkapselgebläseöffnung opposite surface has two buffer receiving openings whose width or geometry are each placed on an outer contour of the buffer and in each of which a buffer is inserted, there is a particularly simple way to attach the Dämmkapsel or the Dämmkapselteils the storage cup. Such attachment of Dämmkapsel or Dämmkapselteils ensures a mechanically decoupled from the vacuum cleaner fan mounting the Dämmkapsel. Characterized in that the or each buffer protrudes through the buffer receiving openings and is contacted only at its projecting beyond the buffer receiving opening end of the support member, the Dämmkapsel is also mechanically decoupled from the fan room.

Figur 1 zeigt in einer teilweise geschnittenen Darstellung ein Staubsaugergebläse 10 in einer Gehäuse- oder Dämmkapsel 12, wobei das Staubsaugergebläse 10 über mindestens zwei Lagerelemente, nämlich einen Lagerring 14 als frontseitiges Lagerelement und zumindest einen Puffer 16 als rückseitiges Lagerelement, in einem Gebläseraum eines Staubsaugers gehalten wird. Von dem Staubsauger sind nur geschnittene Abschnitte eines Gehäuseunterteils 18 sichtbar, die aufgrund ihrer Kontur zusammen mit weiteren, nicht dargestellten Wänden den Gebläseraum zur Aufnahme des Gebläses bilden. Das Gehäuseunterteil besitzt außerdem eine Tasche 20 zur Aufnahme eines später beschriebenen Halteelements 38. Die Lagerelemente, also Lagerring 14 und Puffer 16, sind bevorzugt als Gummibauteile oder ähnlich elastische Teile ausgeführt und bewirken, dass die Dämmkapsel 12 nur in diesen Teilen liegt oder hängt. Es besteht keine mechanisch oder akustisch starre/steife Ankoppelung zum Staubsaugergebläse 10 oder zum Staubsaugergehäuse, insbesondere dessen Gehäuseunterteil 18. Die Orte, an denen sich die mechanisch entkoppelte Lagerung ergibt, sind in Figur 1 mit zwei Pfeilen 22, 24 bezeichnet. FIG. 1 shows in a partially sectional view of a vacuum cleaner fan 10 in a housing or Dämmkapsel 12, wherein the vacuum cleaner fan 10 is held via at least two bearing elements, namely a bearing ring 14 as a front bearing element and at least one buffer 16 as a rear bearing element in a fan room of a vacuum cleaner. Of the vacuum cleaner only cut portions of a housing lower part 18 are visible, which form due to their contour together with other walls, not shown, the fan room for receiving the blower. The lower housing part also has a pocket 20 for receiving a later-described retaining element 38. The bearing elements, so bearing ring 14 and buffer 16 are preferably designed as rubber components or similar elastic parts and cause the Dämmkapsel 12 lies or hangs only in these parts. There is no mechanically or acoustically rigid / rigid coupling to the vacuum cleaner fan 10 or to the vacuum cleaner housing, in particular its lower housing part 18. The locations where the mechanically decoupled storage results are in FIG. 1 denoted by two arrows 22, 24.

Das Staubsaugergebläse 10 umfasst in an sich bekannter Art einen elektrischen Antriebsmotor (Motor) mit einem Lagertopf 26 zur Aufnahme der Baumodule des Motors sowie eine vom Motor angetriebene, mindestens einstufige Gebläseeinheit mit einem Laufrad (beides in der Darstellung nicht sichtbar) und eine Ansaughaube 28 und eventuell eine zwischen Laufrad und Motor befindliche Leitstufe (in der Darstellung in Figur 1 ebenfalls nicht sichtbar).The vacuum cleaner fan 10 includes in a conventional manner an electric drive motor (motor) with a bearing cup 26 for receiving the building modules of the engine and a motor driven, at least one-stage fan unit with an impeller (both not visible in the illustration) and a suction hood 28 and possibly a control stage located between the impeller and the motor (in the illustration in FIG FIG. 1 also not visible).

Figur 1 zeigt die Dämmkapsel 12, wobei erkennbar ist, dass diese aus zwei Dämmkapselteilen, nämlich einem frontseitigen ersten Dämmkapselteil 30 und einem zweiten Dämmkapselteil 32, besteht. Das erste Dämmkapselteil 30 befindet sich im Bereich der Ansaughaube 28. Das zweite Dämmkapselteil 30 befindet sich im Bereich des Lagertopfes 26. FIG. 1 shows the Dämmkapsel 12, wherein it can be seen that this consists of two Dämmkapselteilen, namely a front side Dämmkapselteil 30 and a second Dämmkapselteil 32. The first Dämmkapselteil 30 is located in the region of the suction hood 28. The second Dämmkapselteil 30 is located in the region of the bearing cup 26th

Figur 2 zeigt in einer Explosionsdarstellung die Kombinierbarkeit des Staubsaugergebläses 10 in einer Konfiguration mit den Lagerelementen, aber ohne Dämmkapsel. Die Gebläseeinheit des Staubsaugergebläses 10 ist von der Ansaughaube 28 abgedeckt. In dieser bleibt im Zentrum eine Ansaugöffnung 34 frei. Die Ansaugöffnung 34 wird von einer umlaufenden Wulst 36 umgeben und auf diese Wulst 36 ist der Lagerring 14 so aufsetzbar, dass dieser dort in einem Passsitz gehalten wird. Der Innenradius des Lagerrings 14 ist dazu auf den Außenradius der Wulst 36 und deren sonstige Form abgestimmt. Die Halterung des FIG. 2 shows in an exploded view, the combinability of the vacuum cleaner fan 10 in a configuration with the bearing elements, but without Dämmkapsel. The blower unit of the vacuum cleaner fan 10 is covered by the suction hood 28. In this remains in the center of a suction port 34 free. The suction opening 34 is surrounded by a circumferential bead 36 and on this bead 36, the bearing ring 14 is placed so that it is held there in a snug fit. The inner radius of the bearing ring 14 is matched to the outer radius of the bead 36 and its other shape. The holder of the

Lagerrings 14 an der Wulst 36 wird dadurch erleichtert, dass der Lagerring 14 aus Gummi oder einem vergleichbaren Material hergestellt ist, so dass sich dieser durch leichte Verformung, insbesondere Dehnung, auf die Wulst 36 aufschieben lässt und dort aufgrund der Elastizität des Materials und der dadurch begründeten Federwirkung sowie der ebenfalls durch das Material begründeten Haftreibung sicher im Passsitz gehalten wird.Bearing ring 14 on the bead 36 is facilitated by the fact that the bearing ring 14 is made of rubber or a comparable material, so that this can be postponed by slight deformation, in particular stretching, on the bead 36 and there due to the elasticity of the material and thereby reasoned spring action and the well-founded by the material stiction is securely held in snug fit.

Der Lagerring 14 hat eine kreisförmige Außenkontur und mit dieser Außenkontur wird er von einem Halteelement 38 aufgenommen, das in der Schnittdarstellung in Figur 1 nur ansatzweise erkennbar ist und sich bei einer Konfiguration wie in Figur 1 dargestellt in der Tasche 20 und vor dem ersten Dämmkapselteil 30 auf Höhe des Lagerrings 14 befindet. Das Halteelement 38 ist gabelförmig gestaltet und weist bei der dargestellten Ausführungsform ein U-förmiges Profil auf, das auf den Außenumfang des Lagerrings 14 abgestimmt ist. Das Halteelement 38 kontaktiert bei eingebautem Staubsaugergebläse 10 den Lagerring 14 abschnittsweise entlang dessen Außenumfangsfläche. Als rückseitiges Lagerelement ist zumindest ein Puffer 16 vorgesehen (in Figur 2 nur einmal dargestellt). Zum Anbringen des Puffers 16 weist der Lagertopf 26 des Staubsaugergebläses 10 in einem rückseitigen Abschnitt zumindest einen Zapfen 40 auf, auf den der Puffer 16 aufsteckbar ist und dort wie der Lagerring 14 an der Wulst 36 im Passsitz gehalten wird. Zwei derartige Puffer 16 (in Figur 2 nur einmal dargestellt) werden von einem Trägerelement 42 aufgenommen. Das Trägerelement 42 weist dafür Mittel zur Aufnahme der am Lagertopf 26 angebrachten Puffer 16 auf, nämlich auf den Außenumfang der Puffer 16 abgestellte Pufferaufnahmen 44. Des Weiteren weist das Trägerelement 42 Mittel zu dessen Anbringung am Gehäuseunterteil 18 (Figur 1) auf, nämlich zumindest einen Schaft, in der dargestellten Ausführungsform zwei Schäfte 46, die in entsprechende, im Gehäuseunterteil 18 gebildete und in Figur 1 wegen der Schnittdarstellung nicht sichtbare Aufnahmen einführbar sind.The bearing ring 14 has a circular outer contour and with this outer contour it is received by a holding element 38, which in the sectional view in FIG. 1 is only slightly recognizable and in a configuration as in FIG. 1 shown in the pocket 20 and 30 is located in front of the first Dämmkapselteil at the height of the bearing ring 14. The holding element 38 is designed fork-shaped and has in the illustrated embodiment a U-shaped profile which is matched to the outer circumference of the bearing ring 14. The holding member 38 contacted when installed vacuum cleaner fan 10, the bearing ring 14 in sections along the outer peripheral surface. As a rear bearing element, at least one buffer 16 is provided (in FIG. 2 shown only once). For attaching the buffer 16, the bearing cup 26 of the vacuum cleaner fan 10 in a rear portion at least one pin 40, on which the buffer 16 can be plugged and held there as the bearing ring 14 on the bead 36 in snug fit. Two such buffers 16 (in FIG. 2 shown only once) are received by a support member 42. The support member 42 has for this means for receiving the bearing cup 26 mounted on the buffer 16, namely on the outer periphery of the buffer 16 parked buffer receptacles 44. Furthermore, the support member 42 means for its attachment to the housing base 18 (FIGS. FIG. 1 ), namely at least one shaft, in the illustrated embodiment, two shafts 46 which in corresponding, formed in the housing base 18 and in FIG. 1 because of the sectional view invisible recordings are inserted.

Bei mit dem Staubsaugergebläse 10 kombinierten Lagerelementen, also Lagerring 14 und Puffer 16, besteht der über das Halteelement 38 und das Trägerelement 42 mittelbar hergestellte mechanische Kontakt mit dem Staubsaugergehäuse, also insbesondere dessen Gehäuseunterteil 18, ausschließlich über diese Lagerelemente, so dass eine schwimmende Lagerung gegeben ist, bei der keine mechanisch oder akustisch starre/steife Ankoppelung zum Staubsaugergehäuse besteht.When combined with the vacuum cleaner fan 10 bearing elements, so bearing ring 14 and buffer 16, the indirectly via the support member 38 and the support member 42 made mechanical contact with the vacuum cleaner housing, ie in particular its lower housing part 18, exclusively on these bearing elements, so given a floating storage is where there is no mechanically or acoustically rigid / rigid coupling to the vacuum cleaner housing.

Figur 3 zeigt die Dämmkapsel 12 mit erstem und zweitem Kapselteil 30, 32. Ebenfalls dargestellt sind der Lagerring 14 und zwei Puffer 16. Der Lagerring 14 weist eine Mehrzahl von Ausnehmungen 48 auf, die über dessen Außenumfang verteilt und von der Außenumfangsfläche zurückgesetzt sind. Der erste Dämmkapselteil 30 weist im Bereich einer Dämmkapselgebläseöffnung 50 eine Mehrzahl von Lagerringkontaktelementen 52 auf, die nach Größe und untereinander bestehenden Abstand zur Anbringung der Dämmkapsel 12 bzw. des ersten Dämmkapselteils 30 jeweils in eine der Ausnehmungen 48 entlang der Außenumfangsfläche des Lagerrings 14 einführbar sind. Wenn der Lagerring 14 bereits an der Ansaughaube 28 angebracht ist, erfolgt mit dem Einführen der Lagerringkontaktelemente 52 in die Ausnehmungen 48 des Lagerrings 14 auch das Anbringen der Dämmkapsel 12 an der Ansaughaube 28. Dadurch, dass die Ausnehmungen 48 von der Außenumfangsfläche des Lagerrings 14 zurückgesetzt sind, kann das Halteelement 38 (Figur 2) auch bei einem am Lagerring 14 angebrachten ersten Dämmkapselteil 30 abschnittsweise den Lagerring 14 entlang dessen Außenumfangsfläche kontaktieren. FIG. 3 shows the Dämmkapsel 12 with the first and second capsule part 30, 32. Also shown are the bearing ring 14 and two buffers 16. The bearing ring 14 has a plurality of recesses 48 which are distributed over the outer periphery and are set back from the outer peripheral surface. The first Dämmkapselteil 30 has in the region of Dämmkapselgebläseöffnung 50 a plurality of bearing ring contact elements 52, the size and spacing between them for mounting the Dämmkapsel 12 and the first Dämmkapselteils 30 respectively in one of the recesses 48 along the outer peripheral surface of the bearing ring 14 are inserted. When the bearing ring 14 is already attached to the suction hood 28, with the introduction of the bearing ring contact elements 52 in the recesses 48 of the bearing ring 14 and the attachment of the Dämmkapsel 12 to the suction hood 28. Due to the fact that the recesses 48 of the outer peripheral surface of the bearing ring 14 is reset are, the holding element 38 ( FIG. 2 ) contact the bearing ring 14 along its outer peripheral surface even when the first Dämmkapselteil 30 attached to the bearing ring 14 sections.

Das zweite Gehäuseteil 32 weist in seinem rückseitigen Abschnitt - also auf einer der Dämmkapselgebläseöffnung 50 gegenüberliegenden Seite - zwei Pufferaufnahmeöffnungen 54 (nur eine sichtbar) auf, deren Weite und Geometrie jeweils auf einer Außenkontur der Puffer 16 abgestellt ist und in die jeweils ein Puffer 16 einführbar ist. Ein in die Pufferaufnahmeöffnung 54 eingeführter Puffer 16 reicht beim mit dem Staubsaugergebläse 10 (Figur 2) kombinierten zweiten Dämmkapselteil 32 bis zu dem in Verlängerung der Pufferaufnahmeöffnung 54 befindlichen, am Lagertopf 26 gebildeten Zapfen 40 (Figur 2), so dass jeder Puffer 16 gleichzeitig das zweite Dämmkapselteil 32 und einen der Zapfen 40 kontaktiert. Jeder Puffer 16 bewirkt damit einerseits eine vom Staubsaugergehäuse mechanisch entkoppelte Halterung des Staubsaugergebläses 10 und gleichzeitig eine vom Staubsaugergehäuse und vom Staubsaugergebläse 10 entkoppelte Halterung des zweiten Dämmkapselteils 32.The second housing part 32 has in its rear portion - ie on one of Dämmkapselgebläseöffnung 50 opposite side - two buffer receiving openings 54 (only one visible), whose width and geometry is turned off on an outer contour of the buffer 16 and in each case a buffer 16 inserted is. A buffer 16 inserted into the buffer receiving opening 54 is sufficient to be filled with the vacuum cleaner fan 10 (FIG. FIG. 2 ) combined second Dämmkapselteil 32 up to the extension of the buffer receiving opening 54 located on the bearing cup 26 pin formed 40 ( FIG. 2 ), so that each buffer 16 simultaneously contacts the second Dämmkapselteil 32 and one of the pins 40. Each buffer 16 thus causes on the one hand a mechanically decoupled from the vacuum cleaner housing holder of the vacuum cleaner fan 10 and at the same time a decoupled from the vacuum cleaner housing and the vacuum cleaner fan 10 of the second Dämmkapselteils 32nd

Die beiden Lagerelemente, also Lagerring 14 und Puffer 16, erlauben also eine Halterung des Staubsaugergebläses 10 sowohl mit einer das Staubsaugergebläse 10 umgebenden Dämmkapsel 12 wie auch ohne eine dieses umgebende Dämmkapsel 12.The two bearing elements, ie bearing ring 14 and buffer 16, thus allowing a holder of the vacuum cleaner fan 10 with both the vacuum cleaner fan 10 surrounding Dämmkapsel 12 as well as without this surrounding Dämmkapsel 12th

Bei den Lagerelementen handelt es sich dabei um Gleichteile und unabhängig von der jeweiligen Konfiguration, also Staubsaugergebläse 10 mit Dämmkapsel 12 oder Staubsaugergebläse 10 ohne Dämmkapsel 12, kommen die gleichen Lagerelemente zur Anwendung.The bearing elements are identical parts and regardless of the configuration, so vacuum cleaner fan 10 with insulating capsule 12 or vacuum cleaner 10 without Dämmkapsel 12, the same bearing elements are used.

Figur 4 zeigt auf der linken Seite eine Frontansicht des von der Dämmkapsel 12 umgebenen Staubsaugergebläses 10 mit dort angebrachtem Lagerring 14 und von dem Lagerring 14 gehaltenen ersten Dämmkapselteil 30. In dieser Darstellung ist besonders gut sichtbar, wie der Lagerring 14 abschnittsweise entlang dessen Außenumfangsfläche von dem Halteelement 38 kontaktiert wird. Die rechte Seite der Darstellung in Figur 4 zeigt die rückwärtige Seite des Staubsaugergebläses 10 mit dem dort vorgesehenen Trägerelement 42, das in in Figur 4 nicht sichtbarer Weise zwei Puffer 16 (Figur 3) kontaktiert, so dass diese sowohl zur Halterung des dort vorgesehenen zweiten Dämmkapselteils 32 als auch zur Halterung des Staubsaugergebläses 10 insgesamt und zudem zur drehfesten Lagerung des Staubsaugergebläses 10 wirksam sind, wenn das Trägerelement 42 mit dem Staubsaugergehäuse kombiniert wird. FIG. 4 shows on the left side a front view of the surrounded by the Dämmkapsel 12 vacuum cleaner fan 10 there mounted bearing ring 14 and held by the bearing ring 14 first Dämmkapselteil 30. In this illustration is particularly clearly visible as the bearing ring 14 in sections along the outer peripheral surface of the holding element 38th will be contacted. The right side of the illustration in FIG. 4 shows the rear side of the vacuum cleaner fan 10 with the provided there support member 42, which in in FIG. 4 invisible way two buffers 16 ( FIG. 3 ), so that these both for holding the second Dämmkapselteils 32 provided there and for holding the vacuum cleaner fan 10 in total and also for non-rotatable mounting of the Vacuum cleaner fan 10 are effective when the support member 42 is combined with the vacuum cleaner housing.

Zusammenfassend lässt sich die vorliegende Erfindung damit wie folgt beschreiben: Es wird ein Staubsauger mit einem in einem Gebläseraum angeordneten Staubsaugergebläse 10 angegeben, wobei das Staubsaugergebläse 10 ausschließlich mit mindestens zwei Lagerelementen, nämlich einem Lagerring 14 als frontseitiges Lagerelement und mindestens einem Puffer 16 als rückseitiges Lagerelement, in dem Gebläseraum gehalten wird und wobei die Lagerelemente eine Halterung des Staubsaugergebläses 10 mit und ohne eine dieses umgebende Dämmkapsel 12 erlauben, so dass unabhängig von der Konfiguration des Staubsaugergebläses 10 gleiche Teile für dessen Lagerung und dessen mechanische und akustische Entkopplung vom Staubsaugergehäuse verwendbar sind.In summary, the present invention can thus be described as follows: It is a vacuum cleaner with a arranged in a fan room vacuum cleaner fan 10, said the vacuum cleaner fan 10 exclusively with at least two bearing elements, namely a bearing ring 14 as a front-side bearing element and at least one buffer 16 as a rear bearing element , is held in the fan room and wherein the bearing elements allow a holder of the vacuum cleaner fan 10 with and without a surrounding Dämmkapsel 12, so that regardless of the configuration of the vacuum cleaner fan 10 the same parts for its storage and its mechanical and acoustic decoupling from the vacuum cleaner housing can be used.
