Description

Die vorliegende Erfindung betrifft einen Staubsauger, insbesondere einen Bodenstaubsauger, mit einem Haltegitter für einen zwischen Staubraum und Gebläseraum vorgesehenen Motorschutzfilter. Haltegitter für einen Motorschutzfilter sind bei Staubsaugern an sich bekannt, so z. B. gitterähnliche Aufnahmen für den Motorschutzfilter, die für einen Filterwechsel drehbar oder als Kassette zum Klappen oder als Einschub ausgeführt sind. Siehe z.B das Dokument US 2006/016043 A1 . Speziell bei klappbaren Haltegittern wird mitunter als nachteilig empfunden, dass der Benutzer zum Filterwechsel beide Hände benötigt, nämlich zum einen zum Öffnen und Offenhalten des Haltegitters und sodann zum Einführen des Motorschutzfilters. Das Haltegitter neigt nämlich insbesondere bei Ausführungsformen, bei denen ein Filmscharnier verwendet wird, selbsttätig wieder in die geschlossene Position zurückzukehren.The present invention relates to a vacuum cleaner, in particular a canister vacuum cleaner, with a holding grid for a provided between the dust chamber and fan motor protection filter. Holding grille for a motor protection filter are known in vacuum cleaners per se, such. B. lattice-like recordings for the motor protection filter, which are rotatable for a filter change or designed as a cassette for folding or as a slot. See for example the document US 2006/016043 A1 , Especially with foldable holding gratings is sometimes considered disadvantageous that the user needs to change the filter both hands, namely on the one hand to open and keep open the holding grid and then to insert the motor protection filter. Namely, the holding grid tends to automatically return to the closed position, in particular in embodiments in which a film hinge is used.

Eine Aufgabe der Erfindung besteht entsprechend darin, einen Staubsauger mit einem schwenkbaren Haltegitter anzugeben, bei dem die o. g. Nachteile vermieden werden, so dass sich insbesondere eine vereinfachte Handhabbarkeit ergibt.Accordingly, it is an object of the invention to provide a vacuum cleaner with a pivotable holding grid, in which the o. G. Disadvantages are avoided, so that in particular results in a simplified handling.

Diese Aufgabe wird mit einem Staubsauger mit einem Staubraum und einem Motorraum sowie einem zwischen Staub- und Motorraum angeordneten, verschwenkbaren Haltegitter für einen Motorschutzfilter durch Mittel zur Arretierung des Haltegitters in verschwenkter Position gelöst. Als verschwenkte Position wird dabei die geöffnete Position des Haltegitters angesehen. Die Arretierung des Haltegitters in geschlossener Position ist ebenfalls erforderlich, um die Wirksamkeit des Motorschutzfilters zu gewährleisten.This object is achieved with a vacuum cleaner with a dust chamber and an engine compartment and arranged between the dust and engine compartment, pivotable holding grid for a motor protection filter by means for locking the holding grid in a pivoted position. When pivoted position while the open position of the holding grid is considered. The locking of the retaining grid in the closed position is also required to ensure the effectiveness of the motor protection filter.

Der Vorteil der Erfindung besteht darin, dass aufgrund der Arretierbarkeit des Haltegitters in verschwenkter, also geöffneter Position der Benutzer den Filterwechsel mit einer Hand vornehmen kann, indem zunächst das Haltegitter geöffnet und sodann so weit verschwenkt wird, dass die Arretierung in verschwenkter Position wirksam wird. Sodann kann, ohne das Haltegitter festhalten oder abstützen zu müssen, der Motorschutzfilter angebracht und danach das Haltegitter wieder aus der Arretierung gelöst und geschlossen werden.The advantage of the invention is that due to the lockability of the holding grid in pivoted, ie open position, the user can make the filter change with one hand by first the holding grid is opened and then pivoted so far that the lock in the pivoted position is effective. Then, without having to hold or support the grille, the motor protection filter attached and then the holding grid again released from the lock and closed.

Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Dabei verwendete Rückbeziehungen weisen auf die weitere Ausbildung des Gegenstands des Hauptanspruchs durch die Merkmale des jeweiligen Unteranspruchs hin.Embodiments of the invention are the subject of the dependent claims. Relationships used here point to the further development of the subject-matter of the main claim by the features of the respective sub-claim.

Eine Ausführungsform des Staubsaugers zeichnet sich dadurch aus, dass das oder die Mittel zur Arretierung des Haltegitters eine lösbare Verrastung in der verschwenkten Position bewirkt bzw. bewirken. Eine Verrastung ist für die Arretierung des vergleichsweise leichtgewichtigen Haltegitters ausreichend. Die Verrastung ist des Weiteren auch ausreichend, wenn an dem Haltegitter der ebenfalls leichtgewichtige Motorschutzfilter angebracht wird.An embodiment of the vacuum cleaner is characterized in that the means or means for locking the holding grid causes a releasable locking in the pivoted position or effect. A locking is sufficient for the locking of the comparatively lightweight holding grid. The locking is also sufficient, if also attached to the holding grid of the lightweight motor protection filter.

Wenn das Haltegitter aufgrund einer einseitigen Anlenkung verschwenkbar ist, ergibt sich aufgrund der Schwenkachse eine definierte Position nicht nur für die Beweglichkeit des Haltegitters, sondern auch für die Mittel zu dessen Arretierung, insbesondere die Mittel für dessen lösbare Verrastung.If the holding grid is pivotable due to a one-sided articulation, results due to the pivot axis a defined position not only for the mobility of the holding grid, but also for the means for its locking, in particular the means for its releasable locking.

Als Ort für die Mittel zur Arretierung des Haltegitters kommt eine Position im Bereich der angelenkten Seite des Haltegitters in Betracht, insbesondere im Bereich einer Mitte der angelenkten Seite, so dass das oder die Mittel zur Arretierung des Haltegitters nah an diesem Haltegitter anordenbar sind und damit im Vergleich zu einer etwa möglichen seitlichen Anbringung zusätzlicher konstruktiver Aufwand vermieden wird und im Vergleich zu einer ebenfalls etwa möglichen Anbringung im Bereich der der angelenkten Seite gegenüber liegenden Seite die Einführmöglichkeit des Motorschutzfilters nicht beschränkt wird.As a location for the means for locking the holding grid is a position in the region of the hinged side of the holding grid into consideration, in particular in the region of a center of the hinged side, so that the one or more means for locking the holding grid can be arranged close to this holding grid and thus in Compared to an approximately possible lateral attachment additional design effort is avoided and in comparison to a likewise possible attachment in the region of the hinged side opposite side, the possibility of introducing the motor protection filter is not limited.

Als Mittel zur Arretierung des Haltegitters oder als Mittel zur lösbaren Verrastung des Haltegitters kommen einerseits eine Rastnase und andererseits eine korrespondierende Ausnehmung in Betracht. Solche Arretierungs- oder Rastmittel sind fertigungstechnisch besonders einfach realisierbar, so dass der Zweck der Erfindung auf vergleichsweise kostengünstigem Wege erreichbar ist.As a means for locking the holding grid or as a means for releasably locking the holding grid come on the one hand a locking lug and on the other hand, a corresponding recess into consideration. Such locking or locking means are particularly easy to manufacture, so that the purpose of the invention can be achieved in a relatively inexpensive way.

Wenn die Ausnehmung an ihrer durch die Rastnase kontaktierten Seite einen von der Rastnase kontaktierbaren Vorsprung aufweist, der über eine Fläche, in der die Ausnehmung gebildet ist, hervorsteht, kann die Rastnase kürzer sein, so dass sich eine verbesserte Stabilität oder Steifigkeit der Rastnase ergibt.If the recess has on its contacted by the locking lug side contactable by the detent projection which protrudes over a surface in which the recess is formed, the detent may be shorter, so that there is an improved stability or rigidity of the detent.

Wenn das Haltegitter mit einem Filmscharnier einseitig angelenkt ist und die Mittel zur Arretierung oder lösbaren Verrastung des Haltegitters teilweise dem Haltegitter und teilweise einem damit über das Filmscharnier einstückig verbundenen Haltegitterbasisteil zugeordnet sind, findet die Rastverbindung vollständig innerhalb ein- und desselben (einstückigen) Bauteils statt. Damit entfällt auch eine ansonsten evtl. erforderliche Justierung bei der Montage, mit der zu gewährleisten wäre, dass Rastnase und Ausnehmung als Beispiel für Mittel zur Arretierung des Haltegitters tatsächlich bestimmungsgemäß zusammenwirken, indem die Rastnase lösbar in die Ausnehmung eingreift.If the holding grid is articulated on one side with a film hinge and the means for locking or releasable locking of the holding grid are partially associated with the holding grid and partially associated therewith via the film hinge integrally connected holding grid base part, the locking connection is completely within one and the same (one-piece) component instead. This eliminates an otherwise possibly required adjustment during assembly, which would ensure that locking lug and recess as an example of Means for locking the holding grid actually cooperate as intended by the locking lug releasably engages in the recess.

Figur 1 zeigt ein Gehäuseunterteil 10 eines ansonsten nicht weiter dargestellten Staubsaugers in einer Ausführung als Bodenstaubsauger. Das Gehäuseunterteil 10 umfasst Strukturen zur Bildung eines Staubraums 12 und eines Motorraums 14. Im Staubraum 12 wird im Betrieb des Staubsaugers in an sich bekannter Art und Weise ein nicht dargestellter Staubbeutel angebracht. Im Motorraum 14 wird bei der Montage des Staubsaugers in an sich bekannter Art und Weise ein ebenfalls nicht dargestelltes Staubsaugergebläse angebracht. Zwischen Staub- und Motorraum 12, 14 befindet sich ein im Vergleich zur Längsachse des Gehäuseunterteils 10 vertikal orientiertes Lüftungsgitter 16. Vor oder am Lüftungsgitter 16 ist ein Motorschutzfilter 18 anbringbar, der in seiner Position am Lüftungsgitter 16 durch ein Haltegitter, insbesondere ein verschwenkbares Haltegitter 20, fixiert wird. Nach dem Einbringen des Motorschutzfilters 18 kann das Haltegitter, wie in Figur 2 gezeigt, geschlossen werden. FIG. 1 shows a lower housing part 10 of a vacuum cleaner otherwise not shown in an embodiment as a vacuum cleaner. The lower housing part 10 comprises structures for forming a dust chamber 12 and an engine compartment 14. In the dust chamber 12, a dust bag, not shown, is mounted in a manner known per se during operation of the vacuum cleaner. In the engine compartment 14 a likewise not shown vacuum cleaner fan is mounted during assembly of the vacuum cleaner in a conventional manner. Between the dust and engine compartment 12, 14 is located in relation to the longitudinal axis of the housing base 10 vertically oriented ventilation grille 16. Before or on the ventilation grille 16 is a motor protection filter 18 attachable in its position on the ventilation grille 16 by a holding grid, in particular a pivotable holding grid 20th , is fixed. After inserting the motor protection filter 18, the holding grid, as in FIG. 2 shown to be closed.

Figur 3 zeigt die Situation gemäß Figur 1 in vergrößerter Darstellung und einer geschnittenen Seitenansicht, wobei die Schnittebene etwa mittig durch das Gehäuseunterteil 10 und parallel zur Längsachse des Gehäuseunterteils 10 verläuft. Man erkennt das zwischen Staub- und Motorraum 12, 14 (Figur 1) befindliche Lüftungsgitter 16, das davor angeordnete, verschwenkbare Haltegitter 20 und sodann den Motorschutzfilter 18 in einer Position beim Kombinieren mit dem Haltegitter 20. In der Darstellung sind zwei Rastelemente erkennbar, nämlich ein oberes Rastelement 22, das wirksam wird, wenn das Haltegitter 20 geschlossen wird und dann mit einer entsprechenden Rastöffnung 30 am Lüftungsgitter 16 oder einem Gehäuseelement im oberen Bereich des Lüftungsgitters 16 zusammenwirkt, so dass das Haltegitter 20 in geschlossener Position am Lüftungsgitter 16 arretiert ist. Als weitere Rastelemente sind eine Rastnase 24 und eine für deren Aufnahme vorgesehene Ausnehmung 26 sichtbar, die im Folgenden anhand der vergrößerten Darstellung in Figur 4 weiter erläutert werden. FIG. 3 shows the situation according to FIG. 1 in an enlarged view and a sectional side view, wherein the sectional plane extends approximately centrally through the lower housing part 10 and parallel to the longitudinal axis of the housing lower part 10. It can be seen that between dust and engine room 12, 14 ( FIG. 1 ) located in front of it, pivotable holding grid 20 and then the motor protection filter 18 in a position when combined with the holding grid 20. In the illustration, two locking elements can be seen, namely an upper locking element 22, which is effective when the holding grid 20 is closed is and then cooperates with a corresponding latching opening 30 on the ventilation grille 16 or a housing element in the upper region of the ventilation grille 16, so that the holding grid 20 is locked in the closed position on the ventilation grille 16. As a further latching elements, a detent 24 and provided for receiving the recess 26 are visible, which in the following with reference to the enlarged view in FIG FIG. 4 be explained further.

Figur 4 zeigt einen vergrößerten Ausschnitt aus der Darstellung in Figur 3. Dort ist erkennbar, dass die Rastnase 24 in eine in der geschnittenen Darstellung nur abschnittsweise erkennbare Ausnehmung 26 eingreift. Die Ausnehmung 26 weist einen von der Rastnase 24 kontaktierbaren Vorsprung 28 auf, der über eine Fläche, in der die Ausnehmung 26 gebildet ist, hervorsteht. Beim Verschwenken des Haltegitters 20 kommt die Rastnase 24 mit dem Vorsprung 28 in Kontakt und gleitet beim weiteren Verschwenken aufgrund der an deren Unterseite gebildeten Fase zunächst unter elastischer Verformung an dem Vorsprung 28 vorbei. Sobald die Betätigung des Haltegitters 20 für dessen Verschwenken endet, strebt das Haltegitter 20 aufgrund einer Federvorspannung oder einer Materialelastizität eines z. B. für die Verschenkbarkeit vorgesehenen Filmscharniers teilweise aus der verschwenkten Position zurück, so dass jetzt die Rastnase 24 mit ihrer Oberseite mit dem Vorsprung 28 in Kontakt kommt und so die Bewegung des Haltegitters 20 beschränkt. Das Haltegitter 20 ist damit in verschwenkter Position arretiert. Die Arretierung ist lösbar, weil beim erneuten Betätigen des Haltegitters 20 in Richtung auf dessen geschlossene Position die Oberkante der Rastnase 24 an einer an der Unterseite des Vorsprungs 28 gebildeten Fase unter evtl. elastischer Verformung von sowohl der Rastnase 24 wie auch des Vorsprungs 28 entlang gleitet und damit die Arretierung gelöst wird. FIG. 4 shows an enlarged section of the illustration in FIG. 3 , There it can be seen that the locking lug 24 engages in a recess 26 which is only partially recognizable in the sectioned illustration. The recess 26 has a contactable by the locking lug 24 projection 28 which projects beyond a surface in which the recess 26 is formed. When pivoting the holding grid 20, the detent 24 comes into contact with the projection 28 and slides on further pivoting due to the chamfer formed on the underside of the projection 28 past under elastic deformation. Once the operation of the holding grid 20 ends for pivoting, the holding grid 20 strives due to a spring preload or a material elasticity of a z. B. for Verschenkbarkeit provided film hinge partially back from the pivoted position, so that now the locking lug 24 comes with its top with the projection 28 into contact and thus limits the movement of the holding grid 20. The holding grid 20 is thus locked in the pivoted position. The lock is releasable, because upon re-actuation of the holding grid 20 in the direction of its closed position, the upper edge of the locking lug 24 slides on a bevel formed on the underside of the projection 28 under possibly elastic deformation of both the locking lug 24 and the projection 28 along and thus the lock is released.

Das Haltegitter 20 kann, wie in Figur 4 erkennbar, als einstückiges Element ausgeführt sein. Für die Verschwenkbarkeit ist dann ein Filmscharnier vorgesehen, der ein Haltegitterbasisteil 32 mit dem eigentlichen Gitterteil 34 verbindet. Das Haltegitterbasisteil 32 ist mit dem Gehäuseunterteil 10 des Staubsaugers verbindbar, z.B. durch Einführen in eine dort gebildete und zur formschlüssigen Aufnahme des Haltegitterbasisteils 32 vorgesehene Ausnehmung (nicht dargestellt). In dieser Ausnehmung wird das Haltegitterbasisteil 32 z.B. aufgrund einer sich beim Einführen ergebenden Verrastung gehalten. Bei einem solchen einstückigen Haltegitter 20 sind die Mittel zu dessen Arretierung, im dargestellten Ausführungsbeispiel also die Rastnase 24 und die Ausnehmung 26, dem Gitterteil 34 und der Vorsprung 28 dem Haltegitterbasisteil 32 zugeordnet. Nachdem Gitterteil 34 und Haltegitterbasisteil 32 über das Filmscharnier einstückig verbunden sind, ist ohne weitere Justierung jederzeit eine exakte Positionierung der Mittel 24, 26, 28 zur Arretierung des Haltegitters 20 zueinander gewährleistet, so dass diese ohne zusätzlichen Montageeingriff die Funktion zum arretierten Halten des Haltegitters 20 übernehmen können.The holding grid 20 can, as in FIG. 4 recognizable to be designed as a one-piece element. For the pivotability, a film hinge is then provided, which connects a holding grid base part 32 with the actual grid part 34. The holding grid base part 32 can be connected to the housing lower part 10 of the vacuum cleaner, for example by insertion into a recess formed there and provided for the positive reception of the holding grid base part 32 (not shown). In this recess, the holding grid base part 32 is held, for example, due to a resulting during insertion latching. In such a integral holding grid 20 are the means for locking it, in the illustrated embodiment, therefore, the latching lug 24 and the recess 26, the grid part 34 and the projection 28 associated with the holding grid base part 32. After grid part 34 and holding grid base part 32 are integrally connected via the film hinge, an exact positioning of the means 24, 26, 28 for locking the holding grid 20 is guaranteed to each other without further adjustment at any time, so that this without additional mounting engagement the function for holding locked the holding grid 20th can take over.

Zusammenfassend lässt sich die vorliegende Erfindung damit wie folgt beschreiben: Es wird ein Staubsauger mit einem Staub- und einem Motorraum 12, 14 sowie einem zwischen Staub- und Motorraum 12, 14 angeordneten, verschwenkbaren Haltegitter 20 für einen Motorschutzfilter 18 angegeben, wobei für das Haltegitter 20 Mittel für dessen Arretierung in verschwenkter Position vorgesehen sind, so dass die Bedienung des Haltegitters 20 und das Entfernen oder Anbringen eines Motorschutzfilters 18 erleichtert wird und sich mit wenigen Handgriffen, insbesondere mit nur einer Hand, erledigen lässt.In summary, the present invention can thus be described as follows: It is a vacuum cleaner with a dust and an engine compartment 12, 14 and arranged between a dust and engine compartment 12, 14, pivotable holding grid 20 for a motor protection filter 18, wherein for the holding grid 20 means are provided for the locking in a pivoted position, so that the operation of the holding grid 20 and the removal or attachment of a motor protection filter 18 is facilitated and can be done in a few steps, especially with just one hand.
