Description

Die Erfindung betrifft ein Staubsaugergehäuse mit einem Gehäuseteil und einem eine Wand des Gehäuseteils durchdringenden Anschlussstutzen zur Anbindung eines Staubsaugerschlauchs an das Gehäuseteil.The invention relates to a vacuum cleaner housing with a housing part and a wall of the housing part penetrating connection piece for connecting a vacuum cleaner hose to the housing part.

Bodenstaubsauger weisen einen Saugschlauch bzw. ein Saugrohr auf, durch den Staub an- bzw. eingesaugt und in den Innenraum des Staubsaugers befördert wird. Zur Anbindung des Saugschlauchs bzw. des Saugrohrs an das Gehäuse des Staubsaugers ist ein Anschlussstutzen vorgesehen, der fest mit dem Gehäuse verbunden ist. Der Anschlussstutzen ist beispielsweise in das Gehäuseoberteil eingelassen, eingeklebt oder eingeschweißt und bildet somit einen angeformten Bestandteil des Gehäuseoberteils. Typischerweise ist der Anschlussstutzen in einer solchen Weise gestaltet, dass der Saugschlauch lösbar und drehbar im Anschlussstutzen gelagert werden kann, so dass eine optimale Bewegungsfreiheit im Gebrauch bzw. ein schnelles Abnehmen des Saugschlauchs ermöglicht wird. Ein derartiges herkömmliches Anschlusskonzept ist beispielsweise in der US 2,667,371 A gezeigt. Dort durchdringt ein Anschlussstutzen zur Anbindung eins Saugrohrs oder eines Saugschlauchs ein Staubsaugergehäuse, wobei der Anschlussstutzen mit einer Flanschplatte versehen ist, die mit dem Staubsaugergehäuse verbunden ist.Underground vacuum cleaners have a suction hose or a suction pipe, is sucked by the dust or sucked and transported into the interior of the vacuum cleaner. For connecting the suction hose or the suction pipe to the housing of the vacuum cleaner, a connection piece is provided, which is firmly connected to the housing. The connecting piece is, for example, embedded in the upper housing part, glued or welded and thus forms an integral part of the upper housing part. Typically, the connecting piece is designed in such a way that the suction hose can be releasably and rotatably mounted in the connecting piece, so that an optimal freedom of movement during use or a quick removal of the suction hose is made possible. Such a conventional connection concept is for example in the US 2,667,371 A shown. There penetrates a connection piece for connecting a suction pipe or a suction hose, a vacuum cleaner housing, wherein the connection piece is provided with a flange plate which is connected to the vacuum cleaner housing.

Staubsauger einer Modellklasse werden oftmals in verschiedenen Varianten angeboten, die sich in Bezug auf ihre Saugleistung unterscheiden. Die Saugleistung ist das Produkt aus Unterdruck und (Luft-)Volumenstrom. Eine Steigerung der Saugleistung kann durch die Verwendung eines leistungsstärkeren Motors und/oder durch eine Vergrößerung des Schlauchdurchmessers erfolgen. Eine Vergrößerung des Schlauchdurchmessers geht einher mit höheren Kosten und erfordert eine Vergrößerung des Anschlussstutzens. Staubsaugervarianten mit unterschiedlichen Saugleistungen haben somit typischerweise unterschiedlich geformte Anschlussstutzen. Sollen auf ein- und derselben Geräteplattform mehrere Staubsaugervarianten mit unterschiedlicher Saugleistung (und unterschiedlichem Verkaufspreis) angeboten werden, so erfordert dies die Bereitstellung einer Vielzahl unterschiedlicher Staubsaugergehäuse, da sich die diversen Varianten in Bezug auf die Dimensionierung der Anschlussstutzen unterscheiden. Die Herstellung einer Mehrzahl unterschiedlicher Gehäuse - beispielsweise durch Kunststoff-Spritzguss - geht allerdings einher mit hohen Werkzeugkosten, da für jede Gehäusevariante ein separates Werkzeug erforderlich ist.Vacuum cleaners of a model class are often offered in different variants, which differ in terms of their suction power. The suction power is the product of negative pressure and (air) volume flow. An increase in the suction power can be done by using a more powerful motor and / or by increasing the diameter of the hose. An increase in the hose diameter is associated with higher costs and requires an enlargement of the connection piece. Vacuum cleaner variants with different suction powers thus typically have differently shaped connecting pieces. If several vacuum cleaner variants with different suction power (and different selling price) are to be offered on one and the same appliance platform, this requires the provision of a multiplicity of different vacuum cleaner housings, since the various variants with respect to the Differentiate sizing of the connecting piece. The production of a plurality of different housing - for example by plastic injection - but goes along with high tooling costs, since a separate tool is required for each housing variant.

Der Erfindung liegt die Aufgabe zugrunde, ein Staubsaugergehäuse für eine Staubsaugerplattform mit mehreren Varianten unterschiedlicher Saugleistung bereitzustellen, das kostengünstig herstellbar ist. Das Staubsaugergehäuse soll insbesondere die Integration unterschiedlich dimensionierter Anschlussstutzen ermöglichen.The invention has for its object to provide a vacuum cleaner housing for a vacuum cleaner platform with several variants of different suction power, which is inexpensive to produce. The vacuum cleaner housing should in particular allow the integration of differently dimensioned connecting pieces.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The object is solved by the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

Danach ist dasjenige Gehäuseteil des Staubsaugers, das den Anschlussstutzen trägt, mit einer Aussparung versehen, die die unterschiedlich dimensionierten Anschlussstutzen aufnehmen kann. Die Anschlussstutzen sind mit Flanschplatten versehen, deren Form in einer solchen Weise auf die Öffnung im Staubsauger-Gehäuseteil abgestimmt ist, dass die Flanschplatten unlösbar in die Öffnung eingesetzt werden können. Auf diese Weise kann ein- und dasselbe Gehäuseteil für Staubsauger unterschiedlicher Varianten verwendet werden, da Flanschplatten mit unterschiedlichen Anschlussstutzen in das Gehäuseteil integriert werden können. Die für verschiedene Staubsaugervarianten benötigten Gehäuseteile stimmen in Bezug auf ihre geometrische Ausgestaltung überein und können daher kostengünstig in ein- und demselben Spritzgusswerkzeug gefertigt werden. Das Gehäuseteil ist also universell für die verschiedenen Staubsaugervarianten verwendbar. Zur Herstellung eines Staubsaugergehäuses einer vorgegebenen Variante wird in das (universell verwendbare) Gehäuseteil der an die gewünschte Variante angepasste (anwendungsbezogen dimensionierte) Anschlussstutzen eingefügt.Thereafter, that housing part of the vacuum cleaner, which carries the connection piece, provided with a recess which can accommodate the differently sized connection piece. The connecting pieces are provided with flange plates whose shape is matched in such a way to the opening in the vacuum cleaner housing part, that the flange plates can be used inextricably in the opening. In this way, one and the same housing part can be used for vacuum cleaners of different variants, since flange plates with different connecting pieces can be integrated into the housing part. The housing parts required for various types of vacuum cleaner agree with respect to their geometric configuration and can therefore be manufactured inexpensively in one and the same injection molding tool. The housing part is thus universally usable for the various types of vacuum cleaner. To produce a vacuum cleaner housing of a given variant, the (universally applicable) housing part is adapted to the desired variant (application-dimensioned) connecting piece is inserted.

Das erfindungsgemäße Staubsaugergehäuse kann für Staubsaugervarianten mit unterschiedlicher Saugleistung verwendet werden, da das Gehäuseteil mit unterschiedlichen Anschlussstutzen versehen werden kann, die sich in Bezug auf ihre Außendurchmesser unterscheiden und in Bezug auf die Außenkonturen ihrer Flanschplatten näherungsweise übereinstimmen.The vacuum cleaner housing according to the invention can be used for vacuum cleaner variants with different suction power, since the housing part can be provided with different connecting pieces, which differ with respect to their outer diameter and approximately match with respect to the outer contours of their flange plates.

Das Gehäuseteil, an dem der Anschlussstutzen mit seiner Flanschplatte eingefügt wird, ist vorteilhafterweise der Gehäusedeckel. In einer vorteilhaften Ausführung wird die mit dem Anschlussstutzen verbundene Flanschplatte mittels Ultraschallschweißen mit der Wandung des Gehäuseteils verbunden.The housing part, on which the connecting piece is inserted with its flange plate, is advantageously the housing cover. In an advantageous embodiment, the with connected to the connecting piece flange plate by means of ultrasonic welding to the wall of the housing part.

Zweckmäßigerweise sind die den verschiedenen Anschlussstutzen zugehörigen Flanschplatten näherungsweise eben und einstückig mit dem jeweiligen Anschlussstutzen ausgestaltet. Dies ermöglicht eine einfache Herstellung der Anschlussstutzen durch Spritzgießen, da die Flanschplatte unmittelbar an den Anschlussstutzen angegossen werden kann. Im Anschlussstutzen kann eine Verbindungseinrichtung zur lösbaren Anbindung des Staubsaugerschlauchs vorgesehen sein.Appropriately, the flange of the various connecting pieces are approximately flat and designed in one piece with the respective connecting piece. This allows a simple production of the connecting pieces by injection molding, since the flange plate can be cast directly to the connection piece. In the connection piece, a connection device can be provided for the detachable connection of the vacuum cleaner hose.

Zusätzlich zu dem Anschlussstutzen können in der Flanschplatte weitere Elemente integriert sein, beispielsweise eine Fixiervorrichtung für einen Stromanschluss.In addition to the connecting piece, further elements can be integrated in the flange plate, for example a fixing device for a power connection.

Im Folgenden wird die Erfindung anhand eines in den Figuren dargestellten Ausführungsbeispiels näher erläutert. Dabei zeigen:

Figur 1a zeigt eine Schnittdarstellung eines Ausschnitts eines Gehäuses 2 für einen Bodenstaubsauger 1 mit einem Gehäuseteil 3, in den ein Anschlussstutzen 4a für einen (in Figur 1a nicht dargestellten) Saugschlauch integriert ist. Der Anschlussstutzen 4a durchdringt die Wand 13 des Gehäuseteils 3 und schafft eine Verbindung zwischen einem Staubsaugerinnenraum 14 und einem Staubsaugeraußenraum 15, durch die der durch den Saugschlauch geförderte Staub in einen (in Figur 1 a nicht dargestellten) Staubbeutel im Staubsaugerinnenraum 14 gefördert werden kann. In eine Innenwand des Anschlussstutzens 4a ist eine umlaufende Nut eingeformt, die als Verbindungselement 12a zum lösbaren Fixieren, insbesondere Einklinken, des Saugschlauchs dient. Im vorliegenden Ausführungsbeispiel ist das Gehäuseteil 3 ein Gehäusedeckel 5, der mit einer Abdeckblende 6 versehen ist. FIG. 1a shows a sectional view of a section of a housing 2 for a canister vacuum cleaner 1 with a housing part 3, in which a connecting piece 4a for a (in FIG. 1a not shown) suction hose is integrated. The connecting piece 4 a penetrates the wall 13 of the housing part 3 and creates a connection between a vacuum cleaner interior 14 and a vacuum cleaner outer space 15, through which the dust conveyed through the suction hose into a (in FIG. 1 a) dust bag in the vacuum cleaner interior 14 can be promoted. In an inner wall of the connecting piece 4a, a circumferential groove is formed, which serves as a connecting element 12a for releasably fixing, in particular latching, of the suction hose. In the present embodiment, the housing part 3 is a housing cover 5, which is provided with a cover panel 6.

Wie aus der Detaildarstellung der Figur 2a ersichtlich ist, ist der Anschlussstutzen 4a mit einer näherungsweise ebenen Flanschplatte 7a versehen, die näherungsweise senkrecht zu einer Symmetrieachse 8a des Anschlussstutzens 4a angeordnet ist. Im vorliegenden Ausführungsbeispiel sind Anschlussstutzen 4a und Flanschplatte 7a einstückig ausgebildet und beispielsweise durch Kunststoff-Spritzgießen hergestellt. Auf der Flanschplatte 7a ist neben dem Anschlussstutzen 4a eine Fixiervorrichtung 19 für einen (in den Figuren nicht gezeigten) Stromanschluss vorgesehen. Der Anschlussstutzen 4a hat den einem "herkömmlichen" Anschluss entsprechenden Außendurchmesser 16a von 32 mm.As from the detailed representation of the FIG. 2a it can be seen, the connecting piece 4a is provided with an approximately flat flange plate 7a, which is arranged approximately perpendicular to an axis of symmetry 8a of the connecting piece 4a. In the present embodiment, connecting pieces 4a and flange plate 7a are integrally formed and manufactured, for example, by plastic injection molding. On the flange plate 7a, a fixing device 19 for a (not shown in the figures) power connection is provided in addition to the connecting piece 4a. The connecting piece 4a has the outer diameter 16a of 32 mm corresponding to a "conventional" connection.

Die Flanschplatte 7a mit dem damit verbundenen Anschlussstutzen 4a und der Fixiervorrichtung 19 ist - wie in Figur 1a gezeigt - flächenhaft mit dem Gehäusedeckel 5 verbunden. Hierzu ist der Gehäusedeckel 5 mit einem Gehäuseflansch 9 versehen, der in eine Aussparung 10 des Gehäusedeckels 5 hineinragt. Die Außenkontur der Aussparung 10 ist in einer solchen Weise dimensioniert, dass sie die Aufnahme des Anschlussstutzens 4a und der Fixiervorrichtung 19 gestattet; weiterhin ist der Gehäuseflansch 9 der räumlichen Form und der Außenkontur 17a der Flanschplatte 7a angepasst, so dass die Flanschplatte 7a durch Kleben, Schweißen etc. an den Gehäuseflansch 9 angebunden werden kann. Im vorliegenden Ausführungsbeispiel hat die Aussparung 10 eine näherungsweise ovale Form (siehe hierzu die Aufsicht der Figur 5). Der Gehäuseflansch 9 ist näherungsweise eben und ragt ringförmig in die Aussparung 10 hinein; in Zusammenbaulage der Flanschplatte 7a mit dem Gehäusedeckel 5 überlappt der Gehäuseflansch 9 einen Randbereich 11a der Flanschplatte 7a ringförmig, so dass in diesem Überlappungsbereich eine umlaufende Verbindung , beispielsweise eine Ultraschall-Schweißverbindung, zwischen Gehäuseflansch 9 und der Flanschplatte 7a geschaffen werden kann.The flange plate 7a with the associated connection piece 4a and the fixing device 19 is - as in FIG. 1a shown - areal connected to the housing cover 5. For this purpose, the housing cover 5 is provided with a housing flange 9, which projects into a recess 10 of the housing cover 5. The outer contour of the recess 10 is dimensioned in such a way that it accommodates the Connection piece 4a and the fixing device 19 allowed; Furthermore, the housing flange 9 is adapted to the spatial shape and the outer contour 17a of the flange plate 7a, so that the flange plate 7a can be connected to the housing flange 9 by gluing, welding, etc. In the present embodiment, the recess 10 has an approximately oval shape (see the plan view of Figure 5). The housing flange 9 is approximately flat and projects annularly into the recess 10; in the assembly position of the flange plate 7a with the housing cover 5, the housing flange 9 overlaps an edge region 11a of the flange plate 7a annular, so that in this overlap region a circumferential connection, for example, an ultrasonic welded joint between the housing flange 9 and the flange plate 7a can be created.

Figur 2b zeigt einen Anschlussstutzen 4b, der gegenüber dem Anschlussstutzen 4a der Figur 2a einen größeren Außendurchmesser 16b von 46 mm aufweist. Ein solcher Anschlussstutzen 4b ermöglicht die Anbindung eines groß dimensionierten Saugschlauchs, der eine höhere Saugleistung gestattet als der zum Anschluss an den kleineren Anschlussstutzen 4a vorgesehen Saugschlauch. Der Anschlussstutzen 4b ist mit einer Flanschplatte 7b versehen, die - ebenso wie die Flanschplatte 7a der Figur 2a - näherungsweise senkrecht zu einer Symmetrieachse 8b des Anschlussstutzens 4b angeordnet ist. FIG. 2b shows a connecting piece 4b, opposite the connecting piece 4a of FIG. 2a has a larger outer diameter 16b of 46 mm. Such a connecting piece 4b allows the connection of a large-sized suction hose, which allows a higher suction power than the suction hose provided for connection to the smaller connection piece 4a. The connecting piece 4b is provided with a flange plate 7b, which - as well as the flange plate 7a of FIG. 2a - Is arranged approximately perpendicular to an axis of symmetry 8b of the connecting piece 4b.

Damit auch der größer dimensionierte Anschlussstutzen 4b der Figur 2b in den Gehäusedeckel 5 eingefügt werden kann, ist die Aussparung 10 des Gehäusedeckels 5 in einer solchen Weise dimensioniert, dass der Anschlussstutzen 4b durch die Aussparung 10 hindurchragen kann. Die räumliche Gestaltung des Randbereichs 11b und die Außenkontur 17b der Flanschplatte 7b sind dem Gehäuseflansch 9 angepasst, so dass eine umlaufende Verbindung, beispielsweise eine Ultraschall-Schweißverbindung, zwischen Gehäuseflansch 9 und der Flanschplatte 7a geschaffen werden kann.So that the larger-sized connection piece 4b of FIG. 2b can be inserted into the housing cover 5, the recess 10 of the housing cover 5 is dimensioned in such a manner that the connecting piece 4b can protrude through the recess 10. The spatial configuration of the edge region 11b and the outer contour 17b of the flange plate 7b are adapted to the housing flange 9 so that a peripheral connection, for example an ultrasonic welded connection, can be created between the housing flange 9 and the flange plate 7a.

Der Gehäusedeckel 5 ist also in einer solchen Weise ausgestaltet, dass er sowohl einen herkömmlichen Anschlussstutzen 4a (Figur 2a) als auch einen Anschlussstutzen 4b für einen Saugschlauch mit höherer Saugleistung aufnehmen kann. Durch die in Figur 4 gezeigte ovale Aussparung 10 kann der großdimensionierte Anschlussstutzen 4b, aber auch der kleiner dimensionierte Anschlussstutzen 4a mitsamt der Fixiervorrichtung 19 hindurchgeführt werden. Der Vergleich der Figuren 2a und 2b zeigt, dass die Flanschplatten 7a und 7b bezüglich ihrer Außenkonturen 17a und 17b und der räumlichen Gestaltung ihrer Randbereiche 11a und 11b gleich gestaltet sind, so dass - ungeachtet der unterschiedlichen Formen der auf den Flanschplatten 7a, 7b vorgesehenen Elemente 4a und 19 bzw. 4b, beide Flanschplatten 7a, 7b in gleicher Weise mit dem Gehäusedeckel verbunden werden können. Der Gehäusedeckel 5 ist somit ein Gleichteil, der für verschiedene Varianten von Anschlussstutzen 4a, 4b (entsprechend unterschiedlichen Staubsaugervarianten) verwendet werden kann. Neben den beiden in den Figuren 2a, 2b gezeigten Varianten der Anschlussstutzen 4a, 4b können weitere Varianten vorliegen, die ebenfalls in den Gehäusedeckel 5 eingefügt werden können, sofern sie durch die Aussparung 10 passen und sofern ihre Flanschplatten analog den Flanschplatten 7a, 7b gestaltet ist.The housing cover 5 is thus configured in such a way that it can be connected to both a conventional connecting piece 4a (FIG. FIG. 2a ) as well as a connection piece 4b for a suction hose with higher suction power can absorb. By the in FIG. 4 shown oval recess 10, the large-sized connecting piece 4b, but also the smaller sized connecting piece 4a together with the fixing device 19th be passed. The comparison of FIGS. 2a and 2b shows that the flange plates 7a and 7b with respect to their outer contours 17a and 17b and the spatial configuration of their edge regions 11a and 11b are made identical, so that - regardless of the different shapes of the provided on the flange plates 7a, 7b elements 4a and 19 and 4b, both flange plates 7a, 7b can be connected in the same way with the housing cover. The housing cover 5 is thus a common part, which can be used for different variants of connecting pieces 4a, 4b (corresponding to different types of vacuum cleaner). In addition to the two in the FIGS. 2a, 2b shown variants of the connecting pieces 4a, 4b may be present further variants, which can also be inserted into the housing cover 5, provided that they fit through the recess 10 and if their flange plates analogous to the flange plates 7a, 7b is designed.
