Die Erfindung betrifft eine Bodendüse für einen Staubsauger zur Reinigung und Pflege von Bodenflächen, mit einem Gehäuse, das eine in Bearbeitungsstellung der Bodenfläche zugewandte Unterseite aufweist, an der ein länglicher, quer zur Bearbeitungsrichtung verlaufender Saugmund angeordnet ist, wobei der Saugmund durch eine zugeordnete Saugmundkante begrenzt ist, wobei die Saugmundkante ein Befestigungsteil und eine Lippe aufweist, wobei das Befestigungsteil an der Unterseite befestigt ist und die Lippe gegenüber dem Befestigungsteil beweglich ausgebildet ist. Außerdem betrifft die Erfindung einen Staubsauger mit einer solchen Bodendüse.The invention relates to a floor nozzle for a vacuum cleaner for cleaning and care of floor surfaces, having a housing which has a lower surface in processing position of the bottom surface on which an elongated, extending transversely to the direction of processing suction mouth is arranged, wherein the suction mouth bounded by an associated suction mouth is, wherein the suction mouth edge has a fastening part and a lip, wherein the fastening part is fixed to the underside and the lip is designed to be movable relative to the fastening part. Moreover, the invention relates to a vacuum cleaner with such a floor nozzle.
Im privaten Haushalt sowie im Gewerbe kommen Staubsauger, zur Reinigung von Flächen wie textilen Bodenbelägen und glatten Böden zum Einsatz. Dabei wird zur Staubaufnahme eine Bodendüse des Staubsaugers auf einer Bodenfläche kontinuierlich vor- und zurückgeschoben. Die Staubaufnahmeeffektivität des Staubsaugers hängt dabei stark von der Gestaltung der Bodendüse ab.In the private household as well as in the industry, vacuum cleaners are used to clean surfaces such as textile floor coverings and smooth floors. In this case, a floor nozzle of the vacuum cleaner is continuously pushed back and forth on a floor surface for dust absorption. The dust absorption efficiency of the vacuum cleaner depends strongly on the design of the floor nozzle.

Erfindungsgemäß wird dieses Problem durch eine Bodendüse mit den Merkmalen des Patentanspruchs 1 und einen Staubsauger gemäß Anspruch 11 gelöst. Dadurch, dass die Saugmundkante zwischen dem Befestigungsteil und der Lippe oder Leiste mindestens ein Federelement aufweist, wobei das Federelement eine vertikale Federbewegung der Lippe oder Leiste senkrecht zur Bearbeitungsrichtung ermöglicht, kann sich die Saugmundkante besser an den Bodenbelag der zu reinigenden Bodenfläche anpassen. Durch die vertikale federbelastete Bewegung der Lippe oder Leiste können unterschiedliche und wechselnde Kräfte, die durch Schieben und Ziehen der Bodendüse in Bearbeitungsrichtung entstehen, wirksamer durch die Saugmundkante ausgeglichen werden. Die Leiste selbst ist starr, also aus einem harten Werkstoff ausgebildet, während eine Lippe im klassischen Sinne verformbar, also aus einem elastischen oder weichen Werkstoff, wie Gummi oder einem Elastomer, besteht. Das im folgende mit Lippe bezeichnete Bauteil umfasst hier jedoch beide Varianten, also das klassische verformbare Bauteil sowie die starre Leiste.According to the invention this problem is solved by a floor nozzle with the features of
Mit einer Anordnung einer schwenkbaren Saugmundlippe an einer Bodendüse kann die Staubaufnahmeeffektivität der Bodendüse - insbesondere auf Teppichböden - vorteilhaft erhöht werden, sodass auch bei niedrigen Aufnahmeleistungen gute Performanceklassen bzw. Staubaufnahmewerte erreicht werden können.With an arrangement of a pivotable suction lip on a floor nozzle, the dust absorption efficiency of the floor nozzle - especially on carpets - can be advantageously increased so that good performance classes and dust absorption values can be achieved even at low recording powers.
Die Bodenfläche kann durch einen textilen Bodenbelag wie einen Teppich oder Teppichboden oder durch einen Hartboden wie z. B. ein Holzparkett, Laminat oder einen PVC-Bodenbelag gebildet werden.The floor surface may be covered by a textile floor covering such as a carpet or carpet or by a hard floor such. As a wood parquet, laminate or PVC flooring are formed.
Der Staubsauger kann ein Gebläse zur Erzeugung eines Unterdruckes aufweisen, durch den die über eine zu reinigende Bodenfläche geführte Bodendüse Staub und Schmutz von der Bodenfläche aufnimmt. Hierzu wird die Bodendüse durch den Benutzer mittels Schub- und Zugbewegungen in Bearbeitungsrichtung vor und zurück bewegt. Hierdurch gleitet die Bodendüse über die zu reinigende Bodenfläche. Insbesondere bei langflorigen Teppichen gleitet die Unterseite der Bodendüse über die Bodenfläche, während die Unterseite bei Hartböden beanstandet, gegebenenfalls durch Abstandsborsten, über diese Bodenflächen hinweg schwebt. Der Benutzer kann dazu beispielsweise einen mit dem Saugrohr verbundenen Griff des Staubsaugers handhaben. Damit die Reinigung und Pflege des Bodenbelags möglichst effektiv ausgeführt werden kann, ist der Saugmund länglich ausgebildet und verläuft im Wesentlichen quer zur Bearbeitungsrichtung. Länglich ausgebildet bedeutet in diesem Zusammenhang, dass der vorzugsweise im Wesentlichen rechteckige Saugmund eine größere Länge quer zur Bearbeitungsrichtung aufweist, als Breite in Bearbeitungsrichtung. Die Bodendüse kann auch an einem selbstständig fahrenden Staubsauger, insbesondere Saugroboter, angeordnet sein, sodass die Bearbeitungsrichtung der Bodendüse der Fahrtrichtung des selbstständig fahrenden Staubsaugers entspricht. Ein Staubsaugergehäuse des Staubsaugers kann eine Staubaufnahmekammer aufweisen, in welcher der über die Bodendüse aufgenommene Staub beispielsweise in einem Staubbeutel gesammelt werden kann. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.The vacuum cleaner may have a fan for generating a negative pressure, through which the floor nozzle guided over a floor surface to be cleaned receives dust and dirt from the floor surface. For this purpose, the floor nozzle is moved back and forth by the user by means of push and pull movements in the machine direction. As a result, the floor nozzle slides over the floor surface to be cleaned. Especially in long-pile carpets, the underside of the floor nozzle slides over the bottom surface, while the underside of hard floors soils, possibly floated by spacer bristles, over these bottom surfaces. The user can handle for example a connected to the suction pipe handle of the vacuum cleaner. So that the cleaning and care of the floor covering can be carried out as effectively as possible, the suction mouth is elongated and extends substantially transversely to the machining direction. In this context, elongated means that the preferably substantially rectangular suction mouth has a greater length transversely to the machining direction than the width in the machining direction. The floor nozzle can also be arranged on a self-propelled vacuum cleaner, in particular suction robot, so that the machining direction of the floor nozzle corresponds to the direction of travel of the self-propelled vacuum cleaner. A vacuum cleaner housing of the vacuum cleaner may have a dust receiving chamber in which the dust received via the floor nozzle can be collected, for example, in a dust bag. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass in Bearbeitungsrichtung vor oder in Bearbeitungsrichtung hinter dem Saugmund eine dem Saugmund zugeordnete Saugmundkante an der Unterseite angeordnet ist. Die Anordnung einer Saugmundkante, welche eine vertikale Federbewegung der Lippe ermöglicht, ist bei einer Vorwärtsbewegung der Bodendüse in Bearbeitungsrichtung von besonderem Vorteil, wenn sich diese vor dem Saugmund befindet. Durch eine solche Saugmundkante werden durch die Saugmundkante überstrichene Teppichfasern wirksam aufgebogen, ohne dass ein übermäßiger Kraftaufwand durch den Benutzer bei der Vorschubbewegung erforderlich ist. Die vertikale Federbewegung ermöglicht eine optimale Positionierung der Lippe auf der Bodenfläche auch bei wechselnden Untergründen. Der in der Vorschubbewegung der Lippe nachfolgende Saugmund ermöglicht die wirksame Aufnahme von Schmutz und Dreck aus den von der Lippe aufgebogenen Teppichfasern. Die Anordnung einer entsprechenden Saugmundkante hinter dem Saugmund ermöglicht eine entsprechende vorteilhafte Behandlung der Bodenfläche bei der Rückwärtsbewegung der Bodendüse in Bearbeitungsrichtung.According to an advantageous embodiment of the invention, it is provided that in the processing direction before or in the processing direction behind the suction mouth, a suction mouth associated with the suction mouth is arranged on the underside. The arrangement of a suction mouth edge, which allows a vertical spring movement of the lip is included a forward movement of the floor nozzle in the machining direction of particular advantage when it is in front of the suction mouth. By such a suction mouth edge carpet fibers swept over by the suction mouth edge are effectively bent, without requiring an excessive effort by the user during the advancing movement. The vertical spring movement allows optimal positioning of the lip on the floor surface, even on changing surfaces. The subsequent in the advancing movement of the lip suction mouth allows the effective absorption of dirt and dirt from the bent up from the lip carpet fibers. The arrangement of a corresponding suction mouth behind the suction mouth allows a corresponding advantageous treatment of the bottom surface in the backward movement of the floor nozzle in the machine direction.
Eine vorteilhafte Ausführung ist, dass die Bodendüse wenigstens zwei einem Saugmund zugeordnete Saugmundkanten aufweist, wobei wenigstens eine Saugmundkante an der Unterseite in Bearbeitungsrichtung vor und wenigstens eine Saugmundkante an der Unterseite in Bearbeitungsrichtung hinter dem Saugmund angeordnet ist. Die Anordnung von zwei Saugmundkanten vor und hinter einem Saugmund in Bearbeitungsrichtung ermöglicht ein optimales Aufbiegen der Teppichfasern sowohl in der Vorwärtsbewegung als auch in der Rückwärtsbewegung der Bodendüse in Bearbeitungsrichtung. Das Aufbiegen der Teppichfasern durch die Saugmundkante und das Aufsaugen von Schmutz und Dreck durch den in der jeweiligen Bewegung nachfolgenden Saugmund kann eine optimale Reinigung der Bodenfläche sicherstellen, ohne dass ein deutlich erhöhter Kraftaufwand durch den Benutzer hierfür erforderlich ist.An advantageous embodiment is that the floor nozzle has at least two suction mouth edges associated with a suction mouth, wherein at least one suction mouth edge is arranged on the underside in the machine direction and at least one suction mouth edge on the bottom in the machine direction behind the suction mouth. The arrangement of two suction mouth edges in front of and behind a suction mouth in the machine direction enables optimal bending of the carpet fibers both in the forward movement and in the backward movement of the floor nozzle in the machine direction. The bending of the carpet fibers through the suction mouth edge and the absorption of dirt and dirt by the subsequent in the respective movement suction mouth can ensure optimum cleaning of the floor surface, without a significantly increased force required by the user for this.
Gemäß dem hier vorgestellten Ansatz können bei einem Einsatz eines die vorgeschlagene Bodendüse aufweisenden Bodenpflegegeräts beim Schieben und Ziehen der Bodendüse über einen zu reinigenden Bodenbelag auf die vordere und die hintere Saugmundkante gleiche oder zumindest annähernd gleiche Kräfte in Richtung des Bodenbelags ausgeübt werden. Da mit dem vorgestellten Ansatz die Saugmundkante vor dem Saugmund flexibel auf wechselnde Bedingungen des Bodenbelags reagieren kann, kann die Bodendüse und insbesondere die Lippe gegenüber dem Bodenbelag optimal zum Erzielen guter Staubaufnahmewerte positioniert werden.According to the approach presented here, the same or at least approximately equal forces in the direction of the floor covering can be exerted on the front and the rear Saugmundkante on a flooring to be cleaned in a use of the proposed floor nozzle having floor care device when pushing and pulling the floor nozzle. Since with the presented approach the suction mouth edge in front of the suction mouth can react flexibly to changing conditions of the floor covering, the floor nozzle and in particular the lip opposite the floor covering can be optimally positioned to achieve good dust absorption values.
Eine bevorzugte Ausführung sieht vor, dass die Lippe mindestens einer Saugmundkante um eine quer zur Bearbeitungsrichtung verlaufende Achse schwenkbar ausgebildet ist. Die zusätzliche Verschwenkbarkeit der Lippe bietet eine zusätzliche Möglichkeit für eine Anpassung der Lippenposition an die Eigenschaften der zu reinigenden Bodenfläche. Die Verschwenkung der Lippe ermöglicht eine bessere Ausrichtung für ein wirksames Aufbiegen der überstrichenen Teppichfasern, wobei die durch das Federelement ermöglichte vertikale Bewegung eine optimale Anpassung an wechselnde Eigenschaften der zu reinigenden Bodenfläche bietet.A preferred embodiment provides that the lip of at least one suction mouth edge is designed to be pivotable about an axis extending transversely to the machining direction. The additional pivotability of the lip offers an additional possibility for adapting the lip position to the properties of the floor surface to be cleaned. The pivoting of the lip allows for better alignment for effective bending of the swept carpet fibers, with the vertical element allowed by the spring element Movement provides optimal adaptation to changing properties of the floor surface to be cleaned.
Besonders vorteilhaft ist die Weiterbildung, dass mindestens eine Saugmundkante einen in Bearbeitungsrichtung hinter der Lippe angeordneten, hinteren Schwenkbegrenzungsanschlag zum Begrenzen eines Schwenkausschlags der Lippe in einer ersten Schwenkrichtung und / oder mindestens eine Saugmundkante einen in Bearbeitungsrichtung vor der Lippe angeordneten, vorderen Schwenkbegrenzungsanschlag zum Begrenzen eines Schwenkausschlags der Lippe in einer zu der ersten Schwenkrichtung entgegengesetzten zweiten Schwenkrichtung aufweist. Die Anordnung eines Schwenkbegrenzungsanschlags vor oder hinter der Lippe bietet eine einfache Möglichkeit den Schwenkwinkel der Lippe um die quer zur Bearbeitungsrichtung verlaufende Achse zu begrenzen. Die Begrenzung mittels Schwenkbegrenzungsanschlag ermöglicht, dass die Lippe bei Anschlag an die Begrenzung abgestützt wird, sodass eine weitere Verschwenkung verhindert wird. Diese Abstützung an dem Schwenkbegrenzungsanschlag führt zu einer ausreichend starken Bearbeitung, also Überstreichung, auch von härteren Teppichböden durch die Lippe, wobei die vertikale Verschiebemöglichkeit der Lippe durch das Federelement eine allzu starke Abnutzung der Lippe verhindert und den Kraftaufwand für den Nutzer falls nötig reduziert.Particularly advantageous is the development that at least one suction mouth edge arranged in the processing direction behind the lip, rear pivot limiting stopper for limiting a pivoting movement of the lip in a first pivoting direction and / or at least one Saugmundkante a arranged in the machining direction in front of the lip, front pivot limiting stop for limiting a pivoting deflection the lip has in a direction opposite to the first pivoting direction second pivoting direction. The provision of a swing limit stop in front of or behind the lip provides an easy way to limit the pivoting angle of the lip about the transverse axis to the machining direction. The limitation by means of a swing limit stop enables the lip to be supported against the boundary when it stops, thus preventing further pivoting. This support on the swing limit stop leads to a sufficiently strong processing, ie sweeping, even of harder carpets through the lip, the vertical displacement possibility of the lip by the spring element prevents excessive wear of the lip and reduces the effort for the user if necessary.
Weiter vorteilhaft ist die Ausgestaltung, dass der erste Schwenkbegrenzungsanschlag eine erste Anschlagsfläche für die Lippe bereitstellt und / oder dass der zweite Schwenkbegrenzungsanschlag eine zweite Anschlagsfläche für die Lippe bereitstellt, wobei in einer Ruhestellung der Lippe die erste Anschlagsfläche im Wesentlichen parallel zu der Lippe verläuft und die zweite Anschlagsfläche den Schwenkwinkel der Lippe in Richtung des zweiten Schwenkbegrenzungsanschlags derart begrenzt, dass der Schwenkwinkel der Lippe ausgehend von einer Position senkrecht zur Bearbeitungsrichtung zwischen 45° und 90°, vorzugsweise ca. 70° beträgt. Eine im Wesentlichen parallel zur Ruhestellung der Lippe, also im Wesentlichen senkrecht zur Bearbeitungsrichtung verlaufende Anschlagsfläche bietet die Möglichkeit die verschwenkbare Lippe bei Anschlag mit dieser Fläche gegenüber der Bearbeitungsrichtung aufzustellen, wodurch die überstrichenen Teppichfasern besonders effektiv aufgebogen werden. Eine Anschlagsfläche, die den Schwenkwinkel der Lippe ausgehend von einer Ruhestellung senkrecht zur Bearbeitungsrichtung zwischen 45° und 90° begrenzt, ermöglicht, dass sich die Lippe nach einer entsprechenden Verschwenkung an diese Fläche anlegt, sodass die Lippe einfacher über die Teppichfasern gleitet, ohne dass hierfür ein besonderer Kraftaufwand durch den Benutzer erforderlich wäre.Further advantageous embodiment is that the first pivot limiting stop provides a first abutment surface for the lip and / or that the second pivot limiting stop provides a second abutment surface for the lip, wherein in a rest position of the lip, the first abutment surface is substantially parallel to the lip and the second abutment surface limits the pivoting angle of the lip in the direction of the second pivot limiting stop such that the pivoting angle of the lip, starting from a position perpendicular to the machining direction, is between 45 ° and 90 °, preferably approximately 70 °. A substantially parallel to the rest position of the lip, that is substantially perpendicular to the machining direction stop surface offers the possibility to set up the pivotable lip at stop with this surface opposite the machining direction, whereby the swept carpet fibers are bent particularly effective. A stop surface, which limits the pivoting angle of the lip from a rest position perpendicular to the machining direction between 45 ° and 90 °, allows the lip to abut against this surface after pivoting so that the lip slides more easily over the carpet fibers without this a special effort by the user would be required.
Eine vorteilhafte Ausführungsform der Erfindung sieht vor, dass ein zwischen Saugmund und Lippe angeordneter erster Schwenkbegrenzungsanschlag eine im Wesentlichen parallel zu der Lippe in Ruhestellung verlaufende Anschlagsfläche aufweist, während ein dem ersten Schwenkbegrenzungsanschlag von der Lippe aus gegenüberliegender zweiter Schwenkbegrenzungsanschlag den Schwenkwinkel der Lippe in Richtung des zweiten Schwenkbegrenzungsanschlags derart begrenzt, dass der Schwenkwinkel der Lippe ausgehend von einer Position senkrecht zur Bearbeitungsrichtung zwischen 45° und 90°, vorzugsweise ca. 70° beträgt. Eine im Wesentlichen parallel zur Ruhestellung der Lippe, also im Wesentlichen senkrecht zur Bearbeitungsrichtung verlaufende Anschlagsfläche bietet die Möglichkeit die verschwenkbare Lippe bei Anschlag mit dieser Fläche gegenüber der Bearbeitungsrichtung aufzustellen. Dies hat besondere Vorteile, wenn hierdurch die Lippe aufgestellt wird, welche durch die Vorschub- oder Rückzugbewegung der Bodendüse in Bearbeitungsrichtung die Teppichfasern überstreicht und aufbiegt, welche anschließend von dem nachfolgenden Saugmund von Schmutz und Dreck befreit werden. Eine deutliche Reduzierung des notwendigen Kraftaufwandes beim Vorschub und Rückzug der Bodendüse kann dadurch erreicht werden, dass die Lippe, welche durch die Vorschub- oder Rückzugbewegung in Bearbeitungsrichtung die Teppichfasern überstreicht, welche bereits durch den Saugmund gereinigt wurden, um bis zu 90° verschwenkt wird.An advantageous embodiment of the invention provides that an arranged between the suction mouth and lip first pivot limiting stop has a substantially parallel to the lip in the rest position extending stop surface, while a the first Swivel limiting stop from the lip of opposite second pivot limiting stop the pivot angle of the lip in the direction of the second pivot limiting stop limited such that the pivot angle of the lip from a position perpendicular to the machining direction between 45 ° and 90 °, preferably about 70 °. A substantially parallel to the rest position of the lip, that is substantially perpendicular to the machining direction stop surface offers the possibility to set up the pivotable lip at stop with this surface relative to the machining direction. This has particular advantages, if in this way the lip is placed, which sweeps through the feed or retraction movement of the floor nozzle in the machining direction of the carpet fibers and bends, which are then freed from the subsequent suction of dirt and dirt. A significant reduction in the force required for advancing and retracting the floor nozzle can be achieved by the lip, which sweeps over the carpet fibers by the advancing or retreating movement in the machining direction, which has already been cleaned by the suction mouth, is pivoted by up to 90 °.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass wenigstens eine Saugmundkante länglich ausgebildet ist und sich parallel zum Saugmund erstreckt. Mit einer Saugmundkante, welche länglich ausgebildet ist und parallel zu dem länglich erstreckenden Saugmund verläuft, ist eine möglichst effektive Bearbeitung von Teppichböden während des Staubsaugens möglich, da die Saugmundkante quer zur Bearbeitungsrichtung verläuft und so einen möglichst breiten Bereich der zu reinigenden Bodenfläche abdeckt.According to an advantageous embodiment of the invention, it is provided that at least one suction mouth edge is elongate and extends parallel to the suction mouth. With a suction mouth edge, which is elongated and runs parallel to the longitudinally extending suction mouth, as effective as possible processing of carpets during vacuuming is possible because the suction mouth edge extends transversely to the processing direction and thus covers the widest possible area of the floor surface to be cleaned.
Eine bevorzugte Ausführung sieht vor, dass an der Unterseite mehrere längliche, quer zur Bearbeitungsrichtung verlaufende und parallel zu einander ausgerichtete Saugmünder angeordnet sind, wobei diese Saugmünder durch mindestens eine Saugmundkante begrenzt sind. Die parallele Anordnung mehrerer Saugmünder an der Unterseite einer Bodendüse bietet die Möglichkeit einer besonders effektiven Reinigung. Hierdurch wird gewährleistet, dass die den Saugmündern zugeordneten Saugmundkanten bei der Vorschub- und Rückzugbewegung in Bearbeitungsrichtung nacheinander die zu reinigende Bodenfläche überstreichen. Dieses mehrfache Überstreichen der Bodenfläche durch die Saugmundkanten erhöht die Staubaufnahme, obwohl die von dem Gebläse geförderte Luftmenge sich in diesem Fall auf mehrere Saugmünder aufteilt. Dieses mehrfache Überstreichen der Bodenfläche bietet zudem gegenüber Bodendüsen mit nur einem Saugmund den Vorteil, dass der Benutzer wesentlich früher ein zufriedenstellendes Reinigungsergebnis auf der zu reinigenden Oberfläche erzielt und weniger Vorschub- und Rückzugbewegungen der Bodendüse einleiten muss.A preferred embodiment provides that on the underside a plurality of elongated, transverse to the processing direction and are arranged parallel to each other aligned Saugmünder, these Saugmünder are limited by at least one Saugmundkante. The parallel arrangement of several suction nozzles on the underside of a floor nozzle offers the possibility of a particularly effective cleaning. This ensures that the suction mouths associated Saugmundkanten sweep in the feed and retraction movement in the machine direction successively to be cleaned floor surface. This multiple sweeping of the bottom surface through the Saugmundkanten increases the dust pickup, although the volume of air delivered by the fan is divided in this case on several Saugmünder. This multiple sweeping of the bottom surface also offers over floor nozzles with only a suction mouth the advantage that the user much earlier achieves a satisfactory cleaning result on the surface to be cleaned and must initiate less advancing and retreating movements of the floor nozzle.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass zwischen den Saugmündern an der Unterseite mindestens ein länglicher, quer zur Bearbeitungsrichtung verlaufender Luftkanal angeordnet ist. Mit einem Luftkanal, welcher länglich ausgebildet ist und parallel zu dem länglich erstreckenden Saugmund verläuft, ist ein ausreichend hoher Luftstrom an den Saugmündern während des Staubsaugens erreichbar, da die Saugmundkanten auf einem möglichst breiten Bereich der zu reinigenden Bodenfläche zuverlässig umströmt werden.According to an advantageous embodiment of the invention, it is provided that at least one elongated, transversely to the processing direction extending air duct is arranged between the suction mouths on the underside. With an air duct, which is elongate and runs parallel to the longitudinally extending suction mouth, a sufficiently high air flow at the suction mouths during the Staubsaugens can be achieved since the Saugmundkanten are reliably flowed around as wide as possible to be cleaned bottom surface.
Eine vorteilhafte Ausführung ist, dass der Luftkanal sich von der Unterseite bis zur am Gehäuse gegenüberliegenden Oberseite erstreckt. Die Durchführung des Luftkanals bis zur Oberseite der Bodendüse stellt einen möglichst hohen Luftstrom im gesamten Bereich der Saugmünder sicher.An advantageous embodiment is that the air channel extends from the bottom to the opposite top of the housing. The passage of the air duct to the top of the floor nozzle ensures the highest possible air flow in the entire area of the suction mouth.
Ferner ist Gegenstand der Erfindung ein Staubsauger zur Reinigung und Pflege von Bodenflächen mit einem Gebläse zur Erzeugung eines Unterdruckes zur Aufnahme von Schmutz mittels eines Luftstromes und einem Abscheidesystem zur Reinigung der aufgenommenen Luft vom Schmutz, wobei der bereits und im Folgenden näher beschriebene Staubsauger eine Bodendüse gemäß der vorherigen und nachfolgenden Beschreibung aufweist.Furthermore, the subject matter of the invention is a vacuum cleaner for cleaning and care of floor surfaces with a fan for generating a negative pressure for receiving dirt by means of an air flow and a separation system for cleaning the air taken from the dirt, wherein the already described in more detail below vacuum cleaner and a floor nozzle according to has the previous and following description.
