Description

Die vorliegende Erfindung betrifft ein Gehäuse für einen Staubsauger und insbesondere ein Gehäuse für einen Handstaubsauger gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a housing for a vacuum cleaner and in particular to a housing for a hand-held vacuum cleaner according to the preamble of claim 1.

Staubsauger, insbesondere Haushaltsstaubsauger, werden üblicherweise mit mehreren Zubehörteilen, wie beispielsweise verschiedenen Düsen und Bürsten, verwendet, die jeweils für einen bestimmten Saugvorgang vorgesehen sind. Da diese Düsen jedoch oft nur dann benutzt werden, wenn sie ohne lange Laufwege greifbar sind, werden die Düsen zweckmäßigerweise am oder im Staubsaugergehäuse stets griffbereit mitgeführt. Darüber hinaus kann dem Staubsauger eine Teppichbürste mit eigenem elektrischen Antrieb vorgeschaltet werden, der über ein Kabel mit einem elektrischen Anschluß des Staubsaugers verbunden wird.Vacuum cleaners, in particular household vacuum cleaners, are usually used with several accessories, such as various nozzles and brushes, which are each intended for a specific suction process. However, since these nozzles are often only used if they can be gripped without long walking distances, the nozzles are expediently always at hand on or in the vacuum cleaner housing. In addition, the vacuum cleaner can be preceded by a carpet brush with its own electric drive, which is connected to an electrical connection of the vacuum cleaner via a cable.

Solche Staubsauger sind als Bodenstaubsauger beispielsweise aus der DE-AS 16 28 702 bekannt. In dieser Druckschrift wird ein quaderförmiges Gehäuse eines Bodenstaubsaugers beschrieben, das an seiner Unterseite eine Ausnehmung zum Aufnehmen des aufgerollten Saugschlauches sowie einen zweiten Hohlraum aufweist, zur Aufnahme eines Mundstückes. Der Mundstückaufnahmeraum ist dabei auf der dem Motor abgewandten Seite des Staubbeutelraumes angeordnet. Durch diese Anordnung wird die Bauweise des Staubsaugers sehr lang und somit sperrig, was jedoch bei mit Rädern versehenen Bodenstaubsaugern eine nur untergeordnete Rolle spielt. Zur Verwendung bei Handstaubsaugern ist diese Anordnung jedoch weniger geeignet, da Handstaubsauger kompakt und handlich sein müssen. Darüber hinaus ist die Trennwand zwischen dem Mundstückaufnahmeraum und dem Staubbeutelraum zweistückig und mit Hinterschneidungen ausgebildet, da sie aus spritzgußtechnischen Gründen nur schwer einstückig mit dem Gehäuse herstellbar ist. Somit sind bei dieser Gehäuseform entweder mindestens zwei verschiedene Spritzgußformen notwendig oder eine einzelne, komplizierte. In jedem Fall ist die Herstellung aufwendig und somit teuer.Such vacuum cleaners are known as canister vacuum cleaners, for example from DE-AS 16 28 702. In this publication, a cuboid housing of a vacuum cleaner is described, which has on its underside a recess for receiving the rolled-up suction hose and a second cavity for receiving a mouthpiece. The mouthpiece receiving space is arranged on the side of the dust bag compartment facing away from the motor. This arrangement makes the construction of the vacuum cleaner very long and therefore bulky, which, however, only plays a subordinate role in the case of wheeled vacuum cleaners. However, this arrangement is less suitable for use with handheld vacuum cleaners, since handheld vacuum cleaners must be compact and handy. In addition, the partition between the mouthpiece receiving space and the dust bag space is formed in two parts and with undercuts, since it is difficult to manufacture in one piece with the housing for reasons of injection molding. Thus, with this housing shape either at least two different injection molds are necessary or a single, complicated one. In any case, the production is complex and therefore expensive.

Eine weitere Ausführungsform eines Bodenstaubsaugers ist in der DE-AS 16 28 685 beschrieben. Bei dem in dieser Druckschrift beschriebenen Bodenstaubsauger ist in der oberhalb des Staubbeutels liegenden Gehäusewand eine Vertiefung ausgebildet, in der die meistbenutzte Saugdüse aufgenommen ist. Weitere Saugdüsen werden jedoch in einem gemeinsamen Halter auf diese Vertiefung aufgesetzt, wodurch die glatte Kontur des Gehäuses verloren geht und sich die Gefahr einstellt, daß der Aufsatz sich im Kabel des Staubsaugers verfängt oder an einer Möbelkante hängen bleibt und somit beschädigt wird. Darüber hinaus ist eine solche Befestigung zur Verwendung bei Handstaubsaugern nicht geeignet, da durch deren schnelle Hin- und Herbewegung und die damit verbundene, ständig wechselnde Neigung beim Staubsaugen die Halterung weggeschleudert würde.Another embodiment of a cylinder vacuum cleaner is described in DE-AS 16 28 685. In the cylinder vacuum cleaner described in this document, a recess is formed in the housing wall above the dust bag, in which the most frequently used suction nozzle is accommodated. However, additional suction nozzles are placed in a common holder on this recess, which means that the smooth contour of the housing is lost and the danger arises that the attachment gets caught in the cable of the vacuum cleaner or gets caught on an edge of the furniture and is therefore damaged. In addition, such a fastening is not suitable for use with hand-held vacuum cleaners, since the holder would be thrown away by its rapid reciprocating movement and the associated, constantly changing inclination when vacuuming.

Beiden genannten Staubsauger-Bauformen ist vor allem jedoch der Nachteil gemeinsam, daß die luftdurchlässige Trennwand zwischen Staubbeutelraum und Saugmotor eben ausgebildet ist, so daß der Staubbeutel sich an die Wand anlegen kann, wodurch die Saugwirkung sich nicht mehr Über den gesamten Staubbeutel verteilt, sondern nur noch an den Bereichen des Staubbeutels auftritt, die an den Öffnungen der Trennwand anliegen. Somit wird durch die von der Trennwand entfernt liegenden Bereiche des Staubbeutels kaum noch Luft in den Staubbeutelraum abgesaugt und dadurch die Aufnahmekapazität des Staubbeutels nicht vollständig ausgenützt.However, the two vacuum cleaner designs mentioned above have the disadvantage in common that the air-permeable partition between the dust bag compartment and the suction motor is flat, so that the dust bag can lie against the wall, as a result of which the suction effect is no longer distributed over the entire dust bag, but only still occurs in the areas of the dust bag that abut the openings of the partition. Thus, hardly any air is sucked into the dust bag space through the areas of the dust bag located away from the dividing wall, and therefore the absorption capacity of the dust bag is not fully utilized.

Aufgabe der Erfindung ist es daher, ein gattungsgemäßes Gehäuse für einen Handstaubsauger zu gestalten, das kompakt aufgebaut ist, aus möglichst wenigen Teilen besteht und das eine vollständige Ausnutzung der Kapazität des Staubbeutels ermöglicht.The object of the invention is therefore to design a generic housing for a hand-held vacuum cleaner, which is of compact construction, consists of as few parts as possible and which enables a full utilization of the capacity of the dust bag.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Das Bodenteil des Gehäuses ist einstückig und ohne Hinterschneidungen ausgebildet und daher einfach und somit billig herzustellen. Es weist gemäß der Erfindung Vertiefungen auf, in welche die Zubehörteile von außen leicht eingesetzt werden können, derart, daß sie in den Vertiefungen vollständig aufgenommen werden. Dadurch behält der Handstaubsauger seine ästhetisch ansprechende Form. Das glattflächige Gehäuse verhindert darüber hinaus bei der Handhabung des Staubsaugers ein Hängenbleiben an Möbelkanten, Gardinen und dergleichen.The bottom part of the housing is made in one piece and without undercuts and is therefore simple and therefore inexpensive to manufacture. According to the invention, it has recesses in which the accessories can be easily inserted from the outside, in such a way that they are completely accommodated in the recesses. As a result, the handheld vacuum cleaner maintains its aesthetically pleasing shape. The smooth surface housing also prevents getting stuck on furniture edges, curtains and the like when handling the vacuum cleaner.

Eine erste Gehäusevertiefung ist bei einer besonderen Ausführungsform der Erfindung von einem zwischen dem vorderen Staubraum und dem hinteren Motorraum des Gehäuses angeordneten, zur Bodenseite des Gehäuses hin geöffneten Stauraum für eine Düse gebildet, wobei ein auch bei herkömmlichen Staubsaugergehäusen ohnehin vorhandener Zwischenraum vergrößert ist, der technisch zur Ausbildung des in diesem Bereich verlaufenden Abschnittes der Dichtungsnut vorgesehen ist. Dies hat den Vorteil, daß der Aufbewahrungsraum für die Düse praktisch ohne großen zusätzlichen Aufwand, wie Hinterschneidungen, zusätzliche Spritzgußformen oder Teile, ausgebildet wird, da lediglich ein bereits vorhandener Zwischenraum durch Vergrößerung nutzbar gemacht wird.In a particular embodiment of the invention, a first housing recess is formed by a storage space for a nozzle, which is arranged between the front dust chamber and the rear motor chamber of the housing and is open towards the bottom of the housing, whereby an intermediate space that is already present in conventional vacuum cleaner housings is enlarged, which is technical is provided to form the section of the sealing groove extending in this area. This has the advantage that the storage space for the nozzle is formed practically without much additional effort, such as undercuts, additional injection molds or parts, since only an existing space can be used by enlarging it.

Die Luftdurchtrittsöffnungen in der Zwischenwand zwischen dem Staubraum und dem Motorraum sind zweckmäßigerweise zu beiden Seiten des Stauraumes angeordnet, wobei die die Luftdurchtrittsöffnungen aufweisende Zwischenwand erfindungsgemäß gegenüber der Vorderwand des Stauraumes in Richtung des Motorraumes zurückversetzt ist. Diese Ausbildung hat den Vorteil, daß der in den Staubraum eingesetzte Staubbeutel nicht an den Luftdurchtrittsöffnungen anliegen kann, wodurch eine gleichmäßige Verteilung der Saugwirkung um den gesamten Staubbeutel und somit eine wesentlich bessere Ausnutzung der Kapazität erreicht wird.The air passage openings in the intermediate wall between the dust space and the engine compartment are expediently arranged on both sides of the storage space, the intermediate wall having the air passage openings being set back in the direction of the engine compartment relative to the front wall of the storage space. This training has the advantage that in the dust room inserted dust bag can not rest on the air passage openings, whereby a uniform distribution of the suction effect around the entire dust bag and thus a much better utilization of the capacity is achieved.

Vorteilhafterweise hat der Stauraum im wesentlichen die Form der aufzunehmenden Düse mit geringfügig vergrößerten Abmessungen. Dadurch kann die Düse bequem in den Aufbewahrungsraum eingeführt werden, ohne daß darin ein ungenutzter Raum verbleibt. Zweckmäßigerweise ist an der oberen Wand des Stauraumes ein sich in Richtung der Bodenseite erstreckender ringförmiger, sich nach oben konusförmig erweiternder Ansatz angeformt, auf den die Düse aufsteckbar ist. Damit ist eine besonders einfache Befestigungsmöglichkeit für die Düse vorgesehen.The storage space advantageously has essentially the shape of the nozzle to be accommodated with slightly enlarged dimensions. This allows the nozzle to be conveniently inserted into the storage space without leaving an unused space. A ring-shaped extension, which extends in the direction of the base and extends conically upwards and onto which the nozzle can be attached, is expediently formed on the upper wall of the storage space. This provides a particularly simple attachment option for the nozzle.

Der Stauraum kann im wesentlichen die Form einer Polsterdüse haben, so daß darin die häufig verwendete Polsterdüse untergebracht werden kann.The storage space can essentially have the shape of an upholstery nozzle, so that the frequently used upholstery nozzle can be accommodated therein.

Vorteilhafterweise kann im Bodenbereich des Staubraumes ein in dessen Längsrichtung verlaufender zweiter Stauraum zur Aufnahme einer weiteren Düse ausgebildet sein. Wegen ihrer besonderen Form ist hierzu die langgestreckte Fugendüse besonders geeignet, die ebenfalls bei nahezu jedem Saugvorgang benötigt wird.Advantageously, a second storage space running in the longitudinal direction of the dust space for receiving a further nozzle can be formed in the bottom region of the dust space. Because of its special shape, the elongated crevice nozzle is particularly suitable for this, which is also required for almost every suction process.

Ferner erweist es sich als zweckmäßig, im Bodenbereich des Motorraumes einen in dessen Längsrichtung verlaufenden, zur Bodenseite hin offenen, in den Stauraum einmündenden Kanal zur Aufnahme eines elektrischen Verbindungskabels für eine Teppichbürste auszubilden. Auf diese Weise kann ein weiteres Zubehörteil, nämlich das elektrische Verbindungskabel für eine Teppichbürste, in dem erfindungsgemäßen Gehäuse untergebracht werden. Dabei ist in dem Kanal wenigstens ein Paar gegenüberliegender Klemmarme angeordnet, zwischen denen das Kabel festklemmbar ist. Auf diese Weise ist das Kabel sicher innerhalb des Gehäuses befestigt, so daß es beim Saugvorgang nicht stört.Furthermore, it proves to be expedient to form in the floor area of the engine compartment a channel which runs in the longitudinal direction thereof and is open towards the floor and opens into the storage space for receiving an electrical connecting cable for a carpet brush. In this way, a further accessory, namely the electrical connection cable for a carpet brush, can be accommodated in the housing according to the invention. At least one pair of opposing clamping arms is arranged in the channel, between which the cable can be clamped. In this way, the cable is securely fastened within the housing so that it does not interfere with the suction process.

Vorteilhafterweise ist in einer an den Kanal sich anschließenden Aussparung des Motorraumes eine Steckdose für den Steckeranschluß des Kabels in axialer Ausrichtung auf den Kanal angeordnet. Diese Ausbildung hat den Vorteil, daß der Stecker von unten in die Steckdose einführbar und im Gehäuse versenkt angeordnet ist, wodurch dem Staubsaugergehäuse nicht nur ein gefälligeres Äußeres verliehen wird, sondern auch Winkelstecker und umständliche Kabelführungen vermieden werden.Advantageously, a socket for the plug connection of the cable is arranged in an axial orientation on the channel in a recess in the engine compartment which adjoins the channel. This design has the advantage that the plug can be inserted into the socket from below and sunk in the housing, which not only gives the vacuum cleaner housing a more pleasing appearance, but also avoids angled plugs and cumbersome cable routing.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung einer bevorzugten Auführungsform, sowie anhand der Zeichnung.Further advantages and details of the invention emerge from the following description of a preferred embodiment and from the drawing.

  • 2 shows a cross section along the line 11-11 in Fig. 1st

Das in den Figuren 1 und 2 dargestellte Gehäuse für einen Handstaubsauger hat einen vorderen Staubraum 1 und einen hinteren Motorraum 2, die durch eine Zwischenwand 3 getrennt sind. Der Deckel 4 des Staubraumes 1 ist in Richtung eines in Fig. 1 dargestellten Pfeiles aufklappbar und mittels einer Dichtung 5, die in eine umlaufende Nut 6 eingesetzt ist, im geschlossenen Zustand luftdicht mit dem Bodenteil des Staubraumes 1 verbunden.The housing for a handheld vacuum cleaner shown in FIGS. 1 and 2 has a front dust compartment 1 and a rear engine compartment 2, which are separated by an intermediate wall 3. The lid 4 of the dust chamber 1 can be opened in the direction of an arrow shown in FIG. 1 and is connected in an airtight manner to the bottom part of the dust chamber 1 by means of a seal 5 which is inserted into a circumferential groove 6.

Zwischen dem Staubraum 1 und dem Motorraum 2 ist ein Stauraum 7 zur Aufnahme einer Polsterdüse 7a ausgebildet. Dieser Stauraum 7 hat eine vordere Seitenwand B, eine obere Wand 9, in der ein Abschnitt der umlaufenden Nut 6 ausgebildet ist, und eine hintere Wand 10. Der Stauraum 7 ist zur Bodenseite des Gehäuses hin geöffnet und hat, wie insbesondere aus Fig. 2 zu ersehen, eine Form, die der aufzunehmenden Polsterdüse entspricht. An der oberen Wand 9 des Stauraumes ist ein sich in Richtung der Bodenseite erstreckender ringförmiger, sich nach oben konusförmig erweiternder Ansatz 11 angeformt, auf den die in den Stauraum 7 aufzunehmende Polsterdüse aufsteckbar ist.A storage space 7 for receiving an upholstery nozzle 7a is formed between the dust space 1 and the engine compartment 2. This storage space 7 has a front side wall B, an upper wall 9, in which a section of the circumferential groove 6 is formed, and a rear wall 10. The storage space 7 is open towards the bottom of the housing and, as in particular from FIG. 2 to see a shape that corresponds to the upholstery nozzle to be accommodated. On the upper wall 9 of the storage space, an annular extension 11, which extends in the direction of the bottom side and widens conically upward, onto which the upholstery nozzle to be accommodated in the storage space 7 can be attached.

In der Zwischenwand 3 zwischen dem Staubraum 1 und dem Motorraum 2 sind Luftdurchtrittsöffnungen 20 ausgebildet, die den Staubraum 1 mit dem Motorraum 2 verbinden. Da die die Luftdurchtrittsöffnungen enthaltende Zwischenwand 3 gegenüber der vorderen Wand 8 des Stauraumes 7 zurückversetzt ist, kann ein Staubbeutel 21 nicht in Anlage an die Luftdurchtrittsöffnungen 20 geraten und diese verschließen, so daß eine gleichmäßige Verteilung der Saugwirkung in dem Staubraum sichergestellt ist.In the intermediate wall 3 between the dust chamber 1 and the engine compartment 2, air passage openings 20 are formed which connect the dust compartment 1 to the engine compartment 2. Since the intermediate wall 3 containing the air passage openings is set back in relation to the front wall 8 of the storage space 7, a dust bag 21 cannot come into contact with the air passage openings 20 and close them, so that a uniform distribution of the suction effect in the dust chamber is ensured.

Im Bodenbereich des Staubraumes 1 ist ferner ein in Längsrichtung sich erstreckender zweiter Stauraum 12 ausgebildet, der zur Aufnahme einer Fugendüse 13 dient.In the bottom area of the dust chamber 1 there is also a second storage space 12 which extends in the longitudinal direction and serves to receive a crevice nozzle 13.

Das Staubsaugergehäuse weist ferner im Bodenbereich des Motorraumes 2 einen zur Bodenseite hin offenen, in den Stauraum 7 mündenden Kanal 14 zur Aufnahme eines elektrischen Verbindungskabels 15 für eine Teppichbürste auf. In dem Kanal 14 ist ein Paar gegenüberliegender Klemmarme 16 angeordnet, zwischen denen das Kabel 15 einklemmbar ist. Im Bereich des hinteren Endes des Motorraumes 2 vergrößert sich die Tiefe des Kanals 14 derart, daß ein Stecker 17 des elektrischen Verbindungskabels 15 bequem innerhalb des Kanals geführt und in eine Steckdose 18 eingesteckt werden kann, die in einer sich an den Kanal 14 anschließenden Gehäusekammer 19 angeordnet ist.The vacuum cleaner housing also has, in the floor area of the engine compartment 2, a channel 14, which is open towards the floor and opens into the storage space 7, for receiving an electrical connecting cable 15 for a carpet brush. A pair of opposing clamping arms 16 is arranged in the channel 14, between which the cable 15 can be clamped. In the area of the rear end of the engine compartment 2, the depth of the channel 14 increases in such a way that a plug 17 of the electrical connecting cable 15 can be conveniently guided inside the channel and inserted into a socket 18 which is located in a housing chamber 19 adjoining the channel 14 is arranged.
