Description
Die Erfindung betrifft ein Gerätegehäuse für einen Bodenstaubsauger, welches im Inneren in einen Motorgebläseraum und in einen Staubsammelraum unterteilt ist, mit einem Gehäuseunterteil, einem Gehäuseoberteil und einem Gehäusedeckel, wobei der Staubsammelraum über den Gehäusedeckel verschließbar ist.The invention relates to a device housing for a vacuum cleaner, which is divided into a motor fan room and in a dust collecting space inside, with a lower housing part, an upper housing part and a housing cover, wherein the dust collection chamber is closed via the housing cover.

Bei beiden Ausführungen ist der mehrteilige Aufbau des Gehäuses derart ausgebildet, dass das Gehäuseunterteil als eine an den Seitenwänden hochgezogene Schale ausgebildet ist, welche einen gegenüber dem Staubsammelraum abgedichteten Motorgebläseraum aufweist. Der Motorgebläseraum ist durch das Gehäuseoberteil, an dem der Gehäusedeckel angelenkt ist, abgedeckt. Der Gehäusedeckel ist derart geformt, dass er die Gehäuseoberseite sowie die seitliche Wandung für den Staubsammelraum bildet. Außerdem ist der Gehäusedeckel mit einem Aufnahmeraum für Staubsaugerzubehör ausgebildet, der über einen separaten Deckel verschließbar ist. Die Ausblasluft des Staubsaugers wird aus dem Motorgebläseraum über ein Abluftfilter geleitet. Das Abluftfilter ist unterhalb des Gehäusedeckels angeordnet. Der Gehäusedeckel ist in dem das Abluftfilter überdeckenden Bereich mit Abluftschlitzen ausgebildet.In both embodiments, the multi-part structure of the housing is designed such that the lower housing part is formed as a raised to the side walls shell which has a sealed relative to the dust collecting space engine fan room. The engine fan room is covered by the upper housing part, on which the housing cover is articulated. The housing cover is shaped such that it forms the housing top side and the lateral wall for the dust collection chamber. In addition, the housing cover is formed with a receiving space for vacuum cleaner accessories, which can be closed by a separate lid. The exhaust air of the vacuum cleaner is led out of the engine fan room via an exhaust air filter. The exhaust filter is located below the housing cover. The housing cover is formed in the area covering the exhaust air filter with exhaust air slots.
Durch den Aufbau und die Anordnung des Deckels bedingt, bestehen bei beiden Ausbildungen erhöhte Anforderungen an die Ausbildung der Dichtungen, damit der Unterdruckbereich im Staubsammelraum optimal gegenüber dem Ausblas- bzw. Überdruckbereich des Motorgebläseraumes abzudichten ist. Die stark gewölbte Ausbildung des Gehäusedeckels, der auch die seitliche Gehäusebegrenzung des Staubsammelraumes bildet, ist fertigungstechnisch sehr aufwändig. Außerdem entsteht bei geöffnetem Gehäusedeckel der Eindruck einer instabilen Anordnung.Due to the structure and the arrangement of the lid, there are increased demands on the design of the seals in both embodiments, so that the negative pressure region in the dust collection chamber is optimally sealed against the blow-out or overpressure region of the engine blower compartment. The strongly curved design of the housing cover, which also forms the lateral housing boundary of the dust collection chamber, is very expensive to produce. In addition, the impression of an unstable arrangement arises when the housing cover is open.
Um diese Nachteile zu vermeiden, sind bereits geänderte Aufbauten für Bodenstaubsauger bekannt (z.B. Miele Baureihe S 700), bei denen das mehrteilige Gerätegehäuse ein Unterteil mit seitlich topfförmig hochgezogenen Wänden für die Staubsammelraum-Begrenzung aufweist. Die topfförmigen hochgezogenen Staubsammelraum-Wände weisen eine umlaufende Dichtung auf, die mit dem Gehäusedeckelbereich für den Staubsammelraum dichtend abschließt. Die topfförmig hochgezogenen Staubsammelraum-Wände sind seitlich von einem Gehäuseoberteil abgedeckt, welches den Motorgebläseraum und den Staubsammelraum umschließt. An dem Gehäusebereich, welcher den Motorgebläseraum abdeckt, ist ein flach ausgebildeter Gehäusedeckel mit einem Aufnahmeraum für Staubsaugerzubehör scharnierartig angelenkt. Der den Motorgebläseraum umschließende Teil des Gehäuseoberteils weist eine Aufnahme für ein Abluftfilter auf. Außerdem sind an diesem Gehäusebereich die Ein/Austaste, die Bedienelemente für die Saugleistungsregelung sowie die Taste für die Kabelaufwicklung angeordnet.In order to avoid these drawbacks, already known structures for vacuum cleaners are known (for example Miele S 700 series) in which the multipart device housing has a lower part with laterally pot-shaped raised walls for the dust collecting space delimitation. The cup-shaped raised dust collecting chamber walls have a circumferential seal, which seals with the housing cover area for the dust collection space. The cup-shaped raised dust collecting chamber walls are laterally covered by an upper housing part, which encloses the engine fan room and the dust collecting space. On the housing portion which covers the engine fan room, a flat trained housing cover is hinged with a receiving space for vacuum cleaner accessories like a hinge. The part of the housing upper part enclosing the engine fan chamber has a receptacle for an exhaust air filter. In addition, the on / off button, the controls for the suction power control and the button for cable rewinding are arranged on this housing area.
Die Fertigung des Unterteils mit den seitlich topfförmig hochgezogenen Staubsammelraum-Wänden ist werkzeugtechnisch aufwändig und große, teure Spritzgussmaschinen sind erforderlich. Außerdem kann es aufgrund ungünstiger Wanddickenverhältnisse im Übergangsbereich von Bodenplatte und den seitlich hochgezogenen Wandabschnitten mit den daran ausgebildeten Rippen zu Einfallstellen kommen.The production of the lower part with the cup-shaped raised side dust collecting space walls is technically complex and large, expensive injection molding machines are required. In addition, due to unfavorable wall thickness ratios in the transition region of the base plate and the laterally raised wall sections with the ribs formed thereon, sinkholes may occur.
Aufgrund der Steigerung der Saugleistung ist es außerdem mittlerweile erforderlich, die Staubsammelraum-Wände durch Rippen zu verstärken (siehe
Aus der
Der Erfindung stellt sich somit das Problem einen mehrteiligen stabilen Aufbau für das Gerätegehäuse eines Staubsaugers zu gestalten, der fertigungstechnisch kostengünstig herstellbar ist, bei dem der Staubsammelraum für ein maximal mögliches Volumen ausgebildet ist und bei dem der Unterdruckbereich im Staubsammelraum trotz maximal möglichem Tütenvolumen optimal gegenüber dem Motorgebläseraum abzudichten ist.The invention thus raises the problem of designing a multi-part stable construction for the device housing of a vacuum cleaner, which is inexpensive to produce in terms of manufacturing, in which the dust collecting space is designed for a maximum possible volume is and in which the negative pressure region in the dust collection chamber is to seal optimal despite the maximum possible bag volume with respect to the engine fan room.
Erfindungsgemäß wird dieses Problem durch ein Gerätegehäuse für einen Bodenstaubsauger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a device housing for a vacuum cleaner with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.
Die mit der Erfindung erreichbaren Vorteile bestehen insbesondere in der Gestaltung der einzelnen Gehäuseteile, die durch ihre an optimale Entformungsrichtungen angepasste Gestaltung sowie das geringere Teilegewicht und die geringere projizierte Fläche der Einzelteile in relativ kostengünstig herstellbaren Spritzgießwerkzeugen und Spritzgießmaschinen zu fertigen sind. Geringerer Materialverbrauch für die Einzelteile ermöglicht außerdem kürzere Zykluszeiten beim Spritzgießen, wodurch die Teile insgesamt kostengünstiger herstellbar sind. Durch die nach oben und unten offene, im wesentlichen rohrförmige Ausbildung des Gehäuseeinsatzes kann dieser nach unten entformt werden und bietet so bessere, platzsparendere Möglichkeiten zur Gestaltung von Innenrippen und Dichtungsflächen.The achievable with the present invention consist in particular in the design of the individual housing parts, which are manufactured by their optimal demolding directions adapted design as well as the lower part weight and the lower projected area of the items in relatively inexpensive to produce injection molding and injection molding machines. Lower material consumption for the individual parts also enables shorter cycle times in injection molding, whereby the parts are overall less expensive to produce. By upwardly and downwardly open, substantially tubular design of the housing insert, this can be demoulded down and offers better, space-saving options for the design of inner ribs and sealing surfaces.
In einer vorteilhaften Ausführungsform ist der Gehäuseeinsatz als separates, frei von Gehäusesichtflächen gehaltenes Bauteil ausgebildet. Hierdurch ist eine Fertigung möglich, welche frei von Farbvarianten ist und so die Lagerhaltung und das Montage-Handling erleichtert. Außerdem kann bei einem solchen Einsatz auch auf der Außenseite eine beliebige Rippenstruktur angeformt werden. So kann vorteilhafterweise bei sehr hohen Saugleistungen der Gehäuseeinsatz auf der nach außen gerichteten Fläche mit einer fachwerkartigen Rippenstruktur verstärkt werden.In an advantageous embodiment of the housing insert is designed as a separate, held free from housing sealing surfaces component. As a result, a production is possible, which is free of color variants and so facilitates the storage and assembly handling. In addition, in such an application on the outside of any rib structure can be formed. Thus, advantageously at very high suction rates, the housing insert on the outwardly directed surface can be reinforced with a truss-like rib structure.
Zur Vereinfachung der Montage ist es sinnvoll, wenn an den rohrförmigen Teil des Gehäuseeinsatzes ein den Motorgebläseraum überdeckender, nach unten offener und nach oben bis auf eine Ausblasöffnung geschlossener Einsatzabschnitt angeformt ist. Außerdem ist es aus Designgründen zweckmäßig, wenn der Gehäuseeinsatz durch das als Abdeckrahmen ausgebildete Gehäuseoberteil verkleidet ist.To simplify the assembly, it is useful if a motor fan room overlapping, downwardly open and up to a blow-off closed insert portion is formed on the tubular part of the housing insert. In addition, it is expedient for design reasons, when the housing insert is covered by the cover designed as a housing upper part.
Eine weitere vorteilhafte Ausgestaltungsform, insbesondere bei etwas geringeren Saugleistungen, ist dadurch gekennzeichnet, dass das Gehäuseoberteil doppelwandig ausgebildet ist und dass die Innenwand den Gehäuseeinsatz bildet. Hierdurch wird ein einfacher, leicht zu fertigender Aufbau geschaffen. Zur weiteren Vereinfachung der Fertigung ist es zweckmäßig, wenn das Gehäuseoberteil einen den Motorgebläseraum überdeckenden, nach oben hin im wesentlichen geschlossenen hinteren Gehäuseabschnitt beinhaltet.A further advantageous embodiment, in particular with slightly lower suction powers, is characterized in that the upper housing part is double-walled and that the inner wall forms the housing insert. This creates a simple, easy-to-manufacture construction. To further simplify the production, it is expedient if the upper housing part includes a motor housing area covering, upwardly substantially closed rear housing portion.
Es ist außerdem vorteilhaft, wenn zwischen den Gehäuseeinsatz bildenden Innenwänden und Gehäusesichtflächen bildenden Außenwänden des Gehäuseoberteils senkrechte, in axialer Richtung des Gehäuseeinsatzes verlaufende Außenrippen angeordnet sind. Hierdurch wird auch mit einem einfachen, leicht zu entformenden Rippenaufbau eine ausreichende Verstärkung des Staubsammelraums erreicht.It is also advantageous if between the housing insert forming inner walls and housing sealing surfaces forming outer walls of the upper housing part vertical, in axial Direction of the housing insert extending outer ribs are arranged. As a result, a sufficient reinforcement of the dust collecting space is achieved even with a simple, easily demoulded rib structure.
Durch den nach unten geöffneten Aufbau des Gehäuseeinsatzes kann dieser auf der nach innen gerichteten Fläche mit Innenrippen versehen werden, welche sich in axialer Richtung und zum Staubsammelraum-Inneren erstrecken und welche dann einfach nach unten entformt werden. Aufgrund der möglichen Entformung nach unten kann der Gehäuseeinsatz im Bereich der zum Gehäusedeckel gerichteten Öffnung nach innen gebogen oder abgewinkelt sein und die Innenrippen können bezüglich ihrer zum Staubsammelraum-Inneren gerichteten Ausdehnung wenigstens teilweise unter dem gebogenen oder abgewinkelten Bereich liegen. Die Abwinklung oder Biegung des Gehäuseeinsatzes führt dazu, dass sich dieser sehr eng an die Außenseiten des Gehäuseoberteils bzw. der Abdeckung anschmiegen kann und deshalb das zur Verfügung stehende Bauvolumen nahezu vollständig als Staubsammelraum genutzt wird. Nur aufgrund der Entformungsmöglichkeit nach unten, d. h. durch die Bodenöffnung kann der Gehäuseeinsatz mit einer solchen Abwinklung oder Biegung ausgestattet werden und trotzdem mit Rippen versehen sein.Through the downwardly open structure of the housing insert, this can be provided on the inwardly facing surface with internal ribs which extend in the axial direction and the dust collection chamber interior and which are then easily demolded down. Due to the possible demoulding downwards, the housing insert may be bent or angled inwardly in the region of the opening directed towards the housing cover, and the inner fins may lie at least partially below the bent or angled region with respect to their extent directed to the dust collection chamber interior. The bending or bending of the housing insert causes it to nestle very closely against the outer sides of the housing upper part or the cover and therefore the available volume of construction is almost completely used as a dust collecting space. Only because of the demoulding possibility down, d. H. through the bottom opening of the housing insert can be equipped with such an angling or bending and still be provided with ribs.

Der konstruktive Aufbau des Gerätegehäuses ist in einer Explosionsdarstellung gemäß
In Zusammenbau mit dem Gehäuseoberteil 4 bildet das Gehäuseunterteil 3 den Motorgebläseraum 7 und den Staubsammelraum 9. Damit der Staubsammelraum 9 im Saugbetrieb bei geschlossenem Gehäusedeckel 5 dem durch das Motorgebläse (nicht dargestellt) erzeugten Unterdruck standhält, ist das Gehäuseoberteil 4 im vorderen Teil doppelwandig ausgebildet. Dabei bilden die Außenwände 21 die Gehäusesichtflächen und die Innenwände 22 einen nach unten und nach oben offenen, im wesentlichen rohrförmigen Gehäuseeinsatz 23, welcher wiederum die seitlichen Wandungen des Staubsammelraums 9 erzeugt.
