Saugvorsatz für einen StaubsaugerSuction attachment for a vacuum cleaner
Die vorliegende Erfindung betrifft einen Saugvorsatz für einen Staubsauger mit einem an einem Gehäuse ausgebildeten Saugkanal und mindestens einer im Bereich des Saugkanals angeord- neten drehbar gelagerten Walze, die während des Saugbetriebes antreibbar ist und über Borsten und/oder Leitwände teilweise in Kontakt mit dem Bodenbelag steht, wobei die Walze beweglich gelagert ist und während einer Drehbewegung zusätzlich auch eine schwingende Bewegung der Walze erfolgt.The present invention relates to a suction attachment for a vacuum cleaner with a suction channel formed on a housing and at least one rotatably mounted roller arranged in the region of the suction channel, which can be driven during the suction operation and is partially in contact with the floor covering via bristles and / or baffles , wherein the roller is movably mounted and during a rotational movement additionally also a swinging movement of the roller takes place.
Aus der DE 43 43 432 C2 ist ein Saugvorsatz für einen Staubsauger mit einer sich drehenden Bürstenwalze bekannt, bei dem die Bürsten den Flor im Bereich des Saugmundes bewegen, um eine hohe Schmutzaufnahme zu gewährleisten. Dabei wird der Teppichflor durch die Bürste „aufgebrochen", wenn ein Borstenbüschel in Folge der Rotationsbewegung der Bürstenwalze in bzw. gegen die Schieberichtung der Düse die Teppichoberfläche kämmt. Die Borsten sind jedoch nur in Drehrichtung der Bürstenwalze wirksam.From DE 43 43 432 C2, a suction attachment for a vacuum cleaner with a rotating brush roller is known, in which the brushes move the pile in the region of the suction mouth in order to ensure a high dirt pickup. The carpet is "broken up" by the brush when a bristle tuft meshes with the surface of the carpet due to the rotational movement of the brush roller in or against the direction of sliding of the nozzle, but the bristles act only in the direction of rotation of the brush roll.
Um bei einem solchen Saugvorsatz die Reinigungsleistung zu verbessern, ist es bekanntIn order to improve the cleaning performance in such a suction attachment, it is known
(DE 101 26 354 A1 , DE 102 10 862 A1 , DE 102 00 346 A1 , DE 12 43 838 B), die Bürstenwalze bzw. deren Antrieb so auszubilden, dass sie zusätzlich zur Drehbewegung eine schwingende Bewegung in axialer Richtung durchführen kann. In den vorgenannten Schriften sind verschiedene motorische oder mechanische Antriebe beschrieben.(DE 101 26 354 A1, DE 102 10 862 A1, DE 102 00 346 A1, DE 12 43 838 B), the brush roller or its drive in such a way that they can perform in addition to the rotational movement, a swinging movement in the axial direction. In the aforementioned publications various motor or mechanical drives are described.
Aus der JP 2001 245 832 A ist es bekannt, eine Bürstenwalze bei einem Saugvorsatz mittels Magneten schwimmend zu lagern.From JP 2001 245 832 A it is known to store a brush roller in a suction attachment by means of magnets floating.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Saugvorsatz der eingangs genannten Art dahingehend zu verbessern, dass die Erzeugung der schwingenden Bewegung vereinfacht wird.It is therefore an object of the present invention to improve a suction attachment of the type mentioned in that the generation of the oscillating movement is simplified.
Diese Aufgabe wird mit einem Saugvorsatz mit den Merkmalen des Anspruches 1 gelöst. Die mit der Erfindung erreichbaren Vorteile ergeben sich dadurch, dass zur Erzeugung der schwingenden Bewegung an der Walze Magnete vorgesehen sind, die mit gehäusefesten Magneten dergestalt zusammenwirken, dass bei einer Drehung der Walze diese von den Magneten abwechselnd angezogen und/oder abgestoßen wird. Hierdurch werden auf sehr einfache und kos- tengünstige Weise seitliche Schwingungen erzeugt.This object is achieved with a suction attachment with the features of claim 1. The achievable with the invention advantages result from the fact that magnets are provided for generating the oscillating movement of the roller, which cooperate with fixed housing magnets in such a way that upon rotation of the roller it is alternately attracted to the magnets and / or repelled. As a result, lateral vibrations are generated in a very simple and cost-effective manner.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Achse in eine axiale Richtung oszillierend während einer Drehbewegung angetrieben. Dadurch wird der Flor einerseits in Drehrichtung der Walze und andererseits senkrecht dazu bewegt, so dass die Florfasern für eine bessere Schmutzaufnahme in verschiedene Richtungen aufgebogen werden. Für die Bewegung in axiale Richtung können an mindestens einer Seite der Walze Magnete vorgesehen sein, so dass bei geringem Eigengewicht eine schwingende Lagerung erhalten wird, die weit- gehend verschleißfrei arbeitet. Für einen kompakten Aufbau können dabei Magnete an der Walze gehalten sein und axial benachbart weitere Magnete an dem Gehäuse drehfest montiert sein. Besonders vorteilhaft ist der Einsatz von ringförmigen Magneten mit wechselnder Polung.According to a preferred embodiment of the invention, the axis is driven to oscillate in an axial direction during a rotational movement. As a result, the pile is on the one hand in Direction of rotation of the roller and on the other hand moved perpendicular thereto, so that the Florfasern be bent up for better dirt pickup in different directions. For the movement in the axial direction, magnets may be provided on at least one side of the roller, so that at low dead weight a vibrating bearing is obtained, which works largely wear-free. For a compact design while magnets may be held on the roller and axially adjacent further magnets to be rotatably mounted on the housing. Particularly advantageous is the use of annular magnets with alternating polarity.
Gemäß einer weiteren Ausgestaltung der Erfindung ist mittels der Walze eine senkrecht zum Boden gerichtete Klopfbewegung während einer Drehbewegung ausführbar. Dadurch wird der Flor durch die Borsten und/oder Leitwände klopfend bearbeitet, was die Schmutzaufnahme erhöht.According to a further embodiment of the invention, by means of the roller a directed perpendicular to the ground knocking movement during a rotational movement executable. As a result, the pile is tapped by the bristles and / or baffles, which increases the dirt pickup.
Für die schwimmende Lagerung der Walze können an gegenüberliegenden Seiten Magnete vorgesehen sein, zu denen benachbart stationär angeordnete Magnete vorgesehen sind. Dabei eignen sich besonders gut Seltenerd-Magnete, die sich wegen der starken Magnetfelder eig- nen.For the floating mounting of the roller magnets may be provided on opposite sides to which adjacent stationary magnets are provided. Here, rare earth magnets are particularly suitable, which are suitable because of the strong magnetic fields.
Für eine effektive Reinigung kann die Amplitude der Schwingung der Walze in axiale und/oder vertikale Richtung beispielsweise 0,5 mm bis 2 mm, vorzugsweise etwa 1 mm betragen.For effective cleaning, the amplitude of the vibration of the roller in the axial and / or vertical direction may be, for example, 0.5 mm to 2 mm, preferably about 1 mm.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles mit Bezug auf die beigefügten Zeichnungen näher erläutert. Es zeigen:The invention will be explained in more detail using an exemplary embodiment with reference to the accompanying drawings. Show it:
Figur 1 eine Unteransicht eines erfindungsgemäß ausgebildeten Saugvorsatzes;Figure 1 is a bottom view of an inventively designed suction attachment;
Figur 2 eine Unteransicht des Saugvorsatzes der Figur 1 in modifizierter Position;Figure 2 is a bottom view of the suction attachment of Figure 1 in a modified position;

Figur 4 eine Detailansicht gemäß Figur 3 in veränderter Position.Figure 4 is a detail view of Figure 3 in a changed position.
Ein Saugvorsatz 1 umfasst ein Gehäuse 2, in dem ein Saugkanal 3 ausgebildet ist. In dem Saugkanal 3 ist im Bereich eines Saugmundes an der Unterseite des Gehäuses 2 eine Walze 4 angeordnet, an der radial hervorstehende Borsten 5 festgelegt sind, die in Borstenbüscheln zusammengefasst sind, die sich spiralförmig um die Walze 4 erstrecken.A suction attachment 1 comprises a housing 2, in which a suction channel 3 is formed. In the suction channel 3, a roller 4 is arranged in the region of a suction mouth on the underside of the housing 2, are fixed to the radially projecting bristles 5, which are summarized in bristle tufts, which extend spirally around the roller 4.
An der Walze 4 ist an einem Endabschnitt 6 ein Ringmagnet 7 festgelegt, der durch eine Achse 9 durchgriffen ist. Der Ringmagnet 7 weist zwei oder vier Bereiche unterschiedlicher Polung auf.On the roller 4, a ring magnet 7 is fixed to an end portion 6, which is penetrated by an axis 9. The ring magnet 7 has two or four regions of different polarity.
Benachbart zu dem Ringmagnet 7 ist ein zweiter Ringmagnet 8 drehfest an dem Gehäuse 2 gehalten, der ebenfalls durch die Achse 9 durchgriffen ist. Die Achse 9 ist auf einer Seite an einer Aufnahme des Gehäuses 2 eingefügt und auf der gegenüberliegenden Seite an einem Halteabschnitt 10 innerhalb der Walze 4 festgelegt, wobei die Achse 9 im Bereich des Gehäuses 2 mit Spiel angeordnet ist.Adjacent to the ring magnet 7, a second ring magnet 8 is rotatably held on the housing 2, which is also penetrated by the axis 9. The axis 9 is inserted on one side on a receptacle of the housing 2 and on the opposite side to a Holding portion 10 defined within the roller 4, wherein the axis 9 is arranged in the region of the housing 2 with play.
An der gegenüberliegenden Seite des Gehäuses 2 ist in der Walze 4 ein Antrieb 11 angeordnet, der mit einer Welle 12 in eine Getriebehülse 13 eingreift, so dass bei Drehen der Welle 12 über 5 die Getriebehülse 13 die Walze 4 gedreht wird, beispielsweise mit einer Geschwindigkeit von 2000 bis 3000 U/min.On the opposite side of the housing 2, a drive 11 is arranged in the roller 4, which engages with a shaft 12 in a transmission sleeve 13, so that upon rotation of the shaft 12 via 5 the gear sleeve 13, the roller 4 is rotated, for example at a speed from 2000 to 3000 rpm.
In den Figuren 3 und 4 ist die axiale Beweglichkeit der Walze 4 relativ zu dem Gehäuse 2 im Detail dargestellt. An gegenüberliegenden Seiten der Walze 4 ist jeweils ein Ringmagnet 7 an einem Endabschnitt 6 drehfest gelagert. Der Ringmagnet 7 besitzt dabei Bereiche unterschied- iö licher Polung und ist benachbart zu dem Ringmagnet 8 angeordnet, der drehfest an dem Gehäuse 2 festgelegt ist. Wenn Bereiche gleicher Polung nebeneinander liegen, wird die Walze 4 abgestoßen, so dass sich ein Spalt zwischen den Ringmagneten 7 und 8 ausbildet. Durch die in dem Ringmagneten 8 lose gehaltene Achse 9 ist die Walze 4 axial beweglich gelagert, kann jedoch nicht in radialer Richtung ausbrechen.In Figures 3 and 4, the axial mobility of the roller 4 is shown relative to the housing 2 in detail. On opposite sides of the roller 4, a ring magnet 7 is rotatably mounted at one end portion 6 in each case. In this case, the ring magnet 7 has areas of different polarity and is arranged adjacent to the ring magnet 8, which is secured against rotation on the housing 2. If areas of the same polarity are adjacent to each other, the roller 4 is repelled, so that a gap between the ring magnets 7 and 8 is formed. By the loosely held in the ring magnet 8 axis 9, the roller 4 is mounted axially movable, but can not break out in the radial direction.
i5 Wird die Walze 4 über den Antrieb 11 weitergedreht, sind in einem nächsten Schritt Bereiche unterschiedlicher Polung bei den Ringmagneten 7 und 8 benachbart angeordnet. Dadurch wird der Ringmagnet 7 zusammen mit der Walze 4 zu dem Ringmagneten 8 angezogen und der Spalt zwischen den Ringmagneten 7 und 8 verkleinert sich (Figur 4). Die Achse 9 wird dabei in eine Aufnahme an dem Gehäuse 2 durch den Ringmagneten 8 eingeführt.If the roller 4 is further rotated via the drive 11, regions of different polarity are arranged adjacent to the ring magnets 7 and 8 in a next step. Thereby, the ring magnet 7 is attracted together with the roller 4 to the ring magnet 8 and the gap between the ring magnets 7 and 8 decreases (Figure 4). The axis 9 is thereby introduced into a receptacle on the housing 2 by the ring magnet 8.
20 Es ist bei dem Saugvorsatz 1 möglich, nur an einer Seite Ringmagnete 7 und 8 oder an gegenüberliegenden Seiten der Walze 4 entsprechende Ringmagnete 7 und 8 mit einer entsprechenden Lagerung vorzusehen. Die Ringmagnete 7 und 8 besitzen dabei Magnete aus seltenen Erden, die starke Magnetfelder aufweisen. Durch die schwimmende Lagerung der Walze kann diese weitgehend verschleißfrei in axiale Richtung oszillieren und erzeugt dabei nur20 It is possible in the suction attachment 1, only on one side ring magnets 7 and 8 or on opposite sides of the roller 4 corresponding ring magnets 7 and 8 provided with a corresponding storage. The ring magnets 7 and 8 have magnets of rare earth, which have strong magnetic fields. Due to the floating bearing of the roller, it can oscillate largely wear-free in the axial direction and thereby only generates
25 wenig Geräusche.25 little noises.
In dem gezeigten Ausführungsbeispiel ist nur eine axiale Beweglichkeit der Walze 4 vorgesehen. Es ist natürlich auch möglich, oberhalb der Walze 4 an dem Gehäuse 2 einen entsprechenden Magneten vorzusehen, so dass bei Drehen der Walze 4 der Ringmagnet 7 für eine oszillierende Bewegung in vertikale Richtung sorgt. Dadurch lassen sich Klopfbewegungen der 30 Walze mit den Bürsten 5 realisieren. Möglich ist auch eine Überlagerung einer axialen und einer vertikalen Bewegung. In the embodiment shown, only an axial mobility of the roller 4 is provided. It is of course also possible to provide above the roller 4 on the housing 2 a corresponding magnet, so that when rotating the roller 4, the ring magnet 7 provides for an oscillating movement in the vertical direction. This makes it possible to realize knocking movements of the roller with the brushes 5. It is also possible to superimpose an axial and a vertical movement.
