Description

Die vorliegende Erfindung betrifft eine Düse für einen Staubsauger, insbesondere Handdüse, mit einem Gehäuse, an dem ein Anschlussstutzen zur Verbindung mit einem Staubsauger ausgebildet ist, und einem relativ zu dem Gehäuse drehbar gelagerten Saugmundstück mit einer Saugöffnung, wobei im Bereich der Saugöffnung im Saugmundstück eine drehbare Bürstenwalze angeordnet ist, die über eine Turbine angetrieben ist.The present invention relates to a nozzle for a vacuum cleaner, in particular hand nozzle, with a housing on which a connecting piece for connection to a vacuum cleaner is formed, and a rotatably mounted relative to the housing suction mouthpiece with a suction opening, wherein in the suction opening in the suction mouthpiece rotatable brush roller is arranged, which is driven by a turbine.

Es gibt Düsen für Staubsauger, die ein kastenförmiges Gehäuse aufweisen, an dem an einer Seite ein Anschlussstutzen zur Verbindung mit einem Staubsauger und an der gegenüberliegenden Seite ein Saugmundstück ausgebildet ist, das auf eine zu reinigende Oberfläche auflegbar ist und um eine horizontale Achse an dem Gehäuse verschwenkbar gelagert ist. In dem Saugmundstück kann dabei auch eine Bürstenwalze drehbar angeordnet sein, die über eine im Saugkanal angeordnete Turbine antreibbar ist. Bei solchen kastenförmigen Gehäusen besteht der Nachteil, dass sich Eckbereiche nur schlecht reinigen lassen und auch schwer zugängliche Nischen mit der Düse nicht erreichbar sind.There are nozzles for vacuum cleaners, which have a box-shaped housing, on which on one side a connecting piece for connection to a vacuum cleaner and on the opposite side a suction mouthpiece is formed, which can be placed on a surface to be cleaned and about a horizontal axis on the housing is pivotally mounted. In the suction mouthpiece can also be rotatably arranged a brush roller which is drivable via a turbine arranged in the suction channel. In such box-shaped housings, there is the disadvantage that corner areas can only be cleaned poorly and even difficult-to-reach niches can not be reached with the nozzle.

Aus der DE 36 43 939 ist ein Saugmundstück für ein Saugreinigungsgerät bekannt, bei dem ein L-förmiges Gehäuse vorgesehen ist, wobei an einem Ende ein Stutzen zum Anschluss an ein Saugreinigungsgerät und an dem gegenüberliegenden abgewinkelten Ende ein Saugmundstück mit einer Bürstenwalze vorgesehen ist. Die Bürstenwalze ist dabei über eine Turbine angetrieben, die auf der selben Achse wie die Bürstenwalze befestigt ist. Dadurch ist der Bereich der Saugöffnung an dem Saugmundstück vergleichsweise klein ausgebildet, da der Gehäusebereich mit der Turbine nicht für Reinigungszwecke genutzt wird. Zudem besteht das Problem, dass die Turbine in dem Gehäuse von außen nicht zugänglich ist und leicht durch Flusen verschmutzen kann, was den Antrieb der Bürstenwalze außer Kraft setzen kann.From the DE 36 43 939 a suction nozzle for a Saugreinigungsgerät is known in which an L-shaped housing is provided, wherein at one end a nozzle for connection to a Saugreinigungsgerät and at the opposite angled end a suction mouthpiece is provided with a brush roller. The brush roller is driven by a turbine which is mounted on the same axis as the brush roller. As a result, the area of the suction opening at the suction mouthpiece is comparatively small, since the housing area with the turbine is not used for cleaning purposes. In addition, there is the problem that the turbine in the housing is not accessible from the outside and can easily be polluted by lint, which can disable the drive of the brush roller.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Düse für einen Staubsauger zu schaffen, die einen kompakten Aufbau besitzt und eine effektive Reinigung ermöglicht.It is therefore an object of the present invention to provide a nozzle for a vacuum cleaner, which has a compact structure and allows effective cleaning.

Diese Aufgabe wird mit einer Düse mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a nozzle having the features of claim 1.

Erfindungsgemäß ist das Gehäuse im Wesentlichen L-förmig ausgebildet, wobei das Saugmundstück mit der Bürstenwalze an einem ersten Schenkel und die Turbine an einem zweiten Schenkel des "L" angeordnet sind, und die Turbine über Kraftübertragungsmittel mit der Bürstenwalze gekoppelt ist. Durch die L-förmige Ausbildung des Gehäuses lässt sich ein besonders kompakter Aufbau der Düse erreichen, so dass auch enge Nischen und Eckbereiche mit der Düse gut gereinigt werden können. Dabei kann das Saugmundstück im Verhältnis zum Gehäuse eine großflächige Reinigung vornehmen, da der Antrieb für die Bürstenwalze räumlich von dieser entkoppelt ist, was eine optimierte Gestaltung der Reinigungselemente ermöglicht. Insbesondere kann die Saugöffnung sich über mehr als die Hälfte der Breite der Düse erstrecken.According to the invention, the housing is substantially L-shaped, wherein the suction mouthpiece with the brush roller on a first leg and the turbine on a second leg of the "L" are arranged, and the turbine is coupled via power transmission means with the brush roller. Due to the L-shaped design of the housing, a particularly compact design of the nozzle can be achieved, so that even narrow niches and Corner areas can be cleaned well with the nozzle. In this case, the suction nozzle in relation to the housing make a large-area cleaning, since the drive for the brush roller is spatially decoupled from this, allowing for an optimized design of the cleaning elements. In particular, the suction opening may extend over more than half the width of the nozzle.

Für einen kompakten Aufbau der Düse ist die Turbine vorzugsweise zwischen dem Anschlussstutzen und der Bürstenwalze angeordnet. Die Turbine kann dabei in dem Saugkanal des Gehäuses in einem Abschnitt aufgenommen sein, der auch als Griffabschnitt für die Düse dient.For a compact construction of the nozzle, the turbine is preferably arranged between the connecting piece and the brush roller. The turbine can be accommodated in the suction channel of the housing in a section which also serves as a handle section for the nozzle.

Gemäß einer bevorzugten Ausgestaltung ist im Bereich der Turbine ein entfernbarer Gehäuseabschnitt angeordnet. Dadurch kann bei einer Verunreinigung der Turbine, insbesondere durch Flusen, eine leichte Reinigung erfolgen. Für eine einfache Zugänglichkeit zum Innenraum des Gehäuses kann der entfernbare Gehäuseabschnitt mit dem Gehäuse verrastet sein. Vorzugsweise ist der entfernbare Gehäuseabschnitt als Schieber ausgebildet, der von einer Seite des Gehäuses zur gegenüberliegenden Seite verschiebbar ist, so dass auch hohe Rastkräfte und eine gute Abdichtung des Gehäuses gewährleistet werden können. Zudem lässt sich dann der entfernbare Gehäuseabschnitt durch einen Druckknopf auf einfache Weise herausschieben.According to a preferred embodiment, a removable housing section is arranged in the region of the turbine. This can be done in case of contamination of the turbine, in particular by linting, a slight cleaning. For ease of access to the interior of the housing, the removable housing portion may be latched to the housing. Preferably, the removable housing portion is designed as a slide which is displaceable from one side of the housing to the opposite side, so that high locking forces and a good sealing of the housing can be ensured. In addition, then the removable housing section can be pushed out easily by a push button.

In einer weiteren Ausgestaltung ist an dem Saugmundstück um die Saugöffnung ein abgeflachter, rahmenförmiger Rand ausgebildet, so dass das Saugmundstück bei der Reinigung auf einer flachen Oberfläche parallel zu der Oberfläche verbleibt, während das Gehäuse relativ zu dem Saugmundstück gedreht werden kann. Um bei einer Bewegung des Saugmundstücks über die zu reinigende Fläche ein gutes Reinigungsergebnis zu erzielen, ist vorzugsweise an dem Rand des Saugmundstückes mindestens ein streifenförmiger Flor als Fadenheber vorgesehen.In a further embodiment, a flattened, frame-shaped edge is formed on the suction mouthpiece around the suction opening, so that the suction mouthpiece remains parallel to the surface during cleaning on a flat surface, while the housing can be rotated relative to the suction mouthpiece. In order to achieve a good cleaning result during a movement of the suction mouthpiece over the surface to be cleaned, at least one strip-shaped pile is preferably provided at the edge of the suction mouthpiece as a thread take-up.

Um das Gehäuse der Düse vielseitig einsetzen zu können, ist vorzugsweise mindestens ein leistenförmiger Vorsprung zur Grobschmutzentfernung ausgebildet. Dabei können auch mehrere rippenförmige Vorsprünge in einem Eckbereich des Gehäuses ausgebildet sein, so dass die rippenförmigen Vorsprünge über eine grobe Verschmutzung nach Art eines Schabers bewegt werden können.In order to use the housing of the nozzle versatile, preferably at least one strip-shaped projection for coarse dirt removal is formed. In this case, a plurality of rib-shaped projections may be formed in a corner region of the housing, so that the rib-shaped projections on a coarse contamination in the manner of a scraper can be moved.

Vorzugsweise ist an dem Saugmundstück außen eine ringförmige Nut vorgesehen, in die ein Führungsabschnitt an einem Ausleger des Gehäuses eingreift. Dadurch wird eine besonders gute Führung des Saugmundstückes relativ zu dem Gehäuse gewährleistet. Zudem können an dem Ausleger des Gehäuses Anschläge vorgesehen sein, um die Drehung des Saugmundstückes zu begrenzen.Preferably, an annular groove is provided on the outside of the suction mouthpiece, into which engages a guide section on a cantilever of the housing. As a result, a particularly good guidance of the suction mouthpiece is ensured relative to the housing. In addition, stops may be provided on the boom of the housing to limit the rotation of the suction mouthpiece.

Eine Düse 1 für einen Staubsauger ist als Handdüse ausgebildet und umfasst ein Gehäuse 2, das im Wesentlichen L-förmig ausgebildet ist, wobei an einem Ende ein Anschlussstutzen 3 zur Verbindung mit einem Staubsauger ausgebildet ist. An der gegenüberliegenden Seite des Gehäuses 2 ist ein seitlich hervorstehender Ausleger 4 ausgebildet, an dem ein Saugmundstück 5 drehbar gelagert ist. Das Saugmundstück 5 steht seitlich über den Ausleger 4 hervor.A nozzle 1 for a vacuum cleaner is designed as a hand nozzle and comprises a housing 2 which is substantially L-shaped, wherein at one end a connecting piece 3 is designed for connection to a vacuum cleaner. On the opposite side of the housing 2, a laterally projecting arm 4 is formed, on which a suction nozzle 5 is rotatably mounted. The suction nozzle 5 projects laterally beyond the boom 4.

An dem Saugmundstück 5 ist eine Saugöffnung 6 ausgebildet, die auf eine zu reinigende Oberfläche auflegbar ist. Die Saugöffnung 6 ist von einem Rahmen 8 umgeben.At the suction mouthpiece 5, a suction opening 6 is formed, which can be placed on a surface to be cleaned. The suction opening 6 is surrounded by a frame 8.

Wie in Figur 3 gezeigt ist, kann das Gehäuse 2 relativ zu dem Saugmund 5 gedreht werden. Der Saugmund 5 liegt mit der Saugöffnung 6 auf der zu reinigenden Oberfläche auf, während das Gehäuse 2 um eine horizontale Achse verschwenkbar ist, wobei die durchgezogenen Linien eine Endstellung des Gehäuses 2 zeigen, während die gestrichelte Darstellung des Gehäuses 2' mit dem Anschlussstutzen 3' eine gegenüberliegende Schwenkstellung zeigt.As in FIG. 3 is shown, the housing 2 can be rotated relative to the suction mouth 5. The suction mouth 5 rests with the suction opening 6 on the surface to be cleaned, while the housing 2 is pivotable about a horizontal axis, wherein the solid lines show an end position of the housing 2, while the dashed line of the housing 2 'with the connecting piece 3' an opposite pivoting position shows.

An dem Gehäuse 2 sind in einem Eckbereich mehrere Rippen 7 ausgebildet, die seitlich von dem Gehäuse 2 hervorstehen und zur Grobschmutzentfernung eingesetzt werden. Die Rippen sind entsprechend stabil ausgebildet und stehen beispielsweise um 1 bis 8 mm, vorzugsweise 2 bis 6 mm, von dem Gehäuse 2 hervor. Durch die Anordnung im Eckbereich bilden die Rippen 7 eine Ecke aus, die besonders effektiv für hartnäckigen Schmutz eingesetzt werden kann.On the housing 2 a plurality of ribs 7 are formed in a corner region, which project laterally from the housing 2 and are used for coarse dirt removal. The ribs are correspondingly sturdy and project, for example, by 1 to 8 mm, preferably 2 to 6 mm, from the housing 2. The arrangement in the corner of the ribs 7 form a corner, which can be used particularly effective for persistent dirt.

Beabstandet von dem Saugmund 5 ist das Gehäuse 2 rohrförmig ausgebildet und kann gut von Hand gegriffen werden.Spaced from the suction mouth 5, the housing 2 is tubular and can be easily grasped by hand.

Wie in Figur 4 gezeigt ist, besitzt das Saugmundstück 5 an einer zylindrischen Außenwand eine ringförmige Nut 10, in die ein Führungsabschnitt 11 an dem Ausleger 4 des Gehäuses 2 eingreift. Dadurch kann das Saugmundstück 5 exakt an dem Gehäuse 2 drehbar geführt werden. Zudem sind Anschläge an dem Gehäuse 2 ausgebildet, um die maximale Drehbewegung des Saugmundes 5 zu begrenzen.As in FIG. 4 is shown, the suction nozzle 5 has on a cylindrical outer wall an annular groove 10, in which a guide portion 11 engages on the arm 4 of the housing 2. As a result, the suction mouthpiece 5 can be guided precisely on the housing 2 in a rotatable manner become. In addition, stops on the housing 2 are formed in order to limit the maximum rotational movement of the suction mouth 5.

In dem Saugmundstück 5 ist ferner eine drehbare Bürstenwalze 12 angeordnet, die radial hervorstehende Borsten 13 aufweist. Über die Bürstenwalze 12 kann die zu reinigende Oberfläche beim Saugen gebürstet werden. Die Bürstenwalze 12 ist an einem Ende mit einem Antriebsrad 14 versehen, das über ein Kraftübertragungsmittel 15 in Form eines Riementriebes mit einer Turbine 16 gekoppelt ist.
