Description

Die vorliegende Erfindung betrifft eine Rotordüse für ein Reinigungsgerät, insbesondere für ein Hochdruckreinigungsgerät. Ferner betrifft die Erfindung auch die Verwendung einer Rotordüse in einem Reinigungsgerät, und insbesondere in einem Hochdruckreinigungsgerät.The present invention relates to a rotor nozzle for a cleaning device, in particular for a high-pressure cleaning device. Furthermore, the invention also relates to the use of a rotor nozzle in a cleaning device, and in particular in a high-pressure cleaning device.

Rotordüsen für Reinigungsgeräte sind im Stand der Technik bekannt.Rotary nozzles for cleaning equipment are known in the art.

So ist beispielsweise aus der europäischen Patentschrift EP 0 600 937 B1 eine Rotordüse für ein Hochdruckreinigungsgerät bekannt, bei welcher die Düse in einem Gehäuse angeordnet ist und im Auslassbereich des Gehäuses in einer Lagerpfanne aufgenommen und im Kopfbereich über Bremskörper an der Innenwand des Gehäuses abgestützt ist.For example, from the European Patent EP 0 600 937 B1 a rotor nozzle for a high-pressure cleaning device is known in which the nozzle is arranged in a housing and received in the outlet of the housing in a bearing cup and is supported in the head area via brake body on the inner wall of the housing.

Nachteilig hierbei ist es jedoch, dass sowohl die Lagerung des Düsenkörpers im Bereich der Ausgangsöffnung, als auch die Abstützung über die Bremskörper innerhalb des Rotorgehäuses aufwendig und damit kostenintensiv ist.The disadvantage here, however, is that both the storage of the nozzle body in the region of the outlet opening, as well as the support on the brake body within the rotor housing is expensive and therefore expensive.

Auch die deutsche Gebrauchsmusteranmeldung DE 200 22 303 U1 betrifft eine Rotordüse für ein Reinigungsgerät, bei welcher die Flüssigkeit in tangentialer Richtung in den Innenraum des Gehäuses der Rotordüse eingeleitet wird und hierbei eine, um die Längsachse des Gehäuses rotierende Flüssigkeitssäule bildet. Diese Flüssigkeitssäule nimmt bei ihrer Rotation um die Längsachse den Düsenkörper mit, der auf diese Weise längs eines Kegelmantels, der innerhalb des Gehäuses gebildet ist, umläuft.Also the German utility model application DE 200 22 303 U1 relates to a rotor nozzle for a cleaning device, wherein the liquid is introduced in a tangential direction in the interior of the housing of the rotor nozzle and in this case forms a, about the longitudinal axis of the housing rotating liquid column. This liquid column takes with its rotation about the longitudinal axis with the nozzle body, which in this way along a cone sheath, which is formed within the housing, rotates.

Bei diesem Schutzrecht wird der Düsenkörper im vorderen Bereich in einer Lagerpfanne aufgenommen, welche auch eine Durchlassöffnung für die Flüssigkeit bereitstellt, und ist im oberen Bereich mittels eines Gleitringes gelagert.In this protective right, the nozzle body is received in the front region in a bearing socket, which also provides a passage opening for the liquid, and is mounted in the upper region by means of a sliding ring.

Ausgehend vom Stand der Technik, stellt sich bei der vorliegenden Erfindung die Aufgabe, eine Rotordüse der eingangs genannten Art zu schaffen, die einfach aufgebaut und insbesondere leicht verwendbar ist. Ferner ist es Aufgabe der vorliegenden Erfindung, einen Düsenkörper bereit zu stellen, bei welchem die verwendeten Düsen verändert bzw. ausgetauscht werden können, um insbesondere für unterschiedliche Anwendungen den Flüssigkeitsstrahl am Auslass des Düsenkörpers verändern bzw. den Anforderungen des Bedieners anpassen zu können.Starting from the prior art, the object of the present invention is to provide a rotor nozzle of the type mentioned in the introduction, which has a simple structure and is particularly easy to use.

Erfindungsgemäß weist die Rotordüse für ein Reinigungsgerät, insbesondere ein Hochdruckreinigungsgerät wenigstens ein Gehäuse auf, das mit einer Zuführungsleitung und einem Auslass für eine Flüssigkeit ausgestattet ist.

It should be noted, however, that this does not limit the invention in its design options, but that in particular the modification or adaptation of the bearings, bearing surfaces, sliding surfaces and so on is within the meaning of the present invention.

So zeigt Fig. 1 eine mögliches Ausführungsbeipiel für eine erfindungsgemäße Rotordüse im Querschnitt.Thus, Fig. 1 shows a possible Ausführungsbeipiel for a rotor nozzle according to the invention in cross section.

Gemäß dem hier dargestellten Ausführungsbeispiels wird eine Reinigungsflüssigkeit wie beispielsweise Wasser mit oder ohne Zusätzen über die Zuleitung 1 der Rotordüse zugeführt. Neben Wasser kann auch als Reinigungsflüssigkeit ein Reinigungsmedium wie beispielsweise Wasserdampf und dergleichen verwendet werden. Die Reinigungsflüssigkeit strömt über die Öffnungen 6 der Platte 5 in den konusförmigen Innenabschnitt des Gehäuses, gelangt anschließend über die Öffnungen des Düsenkörpers 11 zur Düse 12, den Düsenkanal 19 und verlässt die Rotordüse über die Mündung der Düse bzw. des Auslasses der Rotordüse. Bevorzugt ist die Länge der Düse derart gewählt, dass sich die Mündung der Düse innerhalb des Auslasses 8 der Rotordüse befindet.According to the embodiment shown here, a cleaning liquid such as water is supplied with or without additives via the supply line 1 of the rotor nozzle. Besides water, a cleaning medium such as water vapor and the like may also be used as the cleaning liquid. The cleaning liquid flows via the openings 6 of the plate 5 in the conical inner portion of the housing, then passes through the openings of the nozzle body 11 to the nozzle 12, the nozzle channel 19 and leaves the rotor nozzle over the mouth of the nozzle or the outlet of the rotor nozzle. Preferably, the length of the nozzle is chosen such that the mouth of the nozzle is located within the outlet 8 of the rotor nozzle.

Hierbei besteht die Rotordüse aus einer Gehäusehaube 7 und einem Gehäusefuß 2, in welchem die Zuführungsleitung 1 angeordnet ist. Der Gehäusefuß 2 ist über eine Gewindeverbindung 3 mit der Gehäusehaube 7 verbunden und weist ein Dichtelement vorzugsweise einen O-Ring auf. Selbstverständlich kann die Abdichtung auch durch andere Arten, wie sie im Stand der Technik bekannt sind, erfolgen.Here, the rotor nozzle consists of a housing cover 7 and a housing foot 2, in which the supply line 1 is arranged. The housing foot 2 is connected via a threaded connection 3 with the housing cover 7 and has a sealing element, preferably an O-ring. Of course, the seal can also be made by other types, as they are known in the art.

In axialer Richtung ist zwischen dem Gehäusefuß 2 und der Gehäusehaube 7 eine Düsenplatte 5 angeordnet, welche zumindest eine Durchführung 6 aufweist, durch welche die Flüssigkeit, welche über die Zuführungsleitung 1 der Rotationsdüse zugeführt wird, in den kegelförmigen Innenabschnitt der Rotationsdüse mündet. Dabei sind die Öffnungen der Düsenplatte in der Art gestaltet, dass die Flüssigkeit in einem vorgegebenen Winkel in den konusförmigen Innenbereich der Rotordüse eintritt, wodurch der Düsenkörper 11 mit der Düse 12 in Bewegung, vorzugsweise in Rotationsbewegung, versetzt wird.In the axial direction, a nozzle plate 5 is arranged between the housing foot 2 and the housing cover 7, which has at least one passage 6 through which the liquid, which is supplied via the supply line 1 of the rotary nozzle, opens into the conical inner portion of the rotary nozzle. In this case, the openings of the nozzle plate are designed in such a way that the liquid enters at a predetermined angle in the conical inner region of the rotor nozzle, whereby the nozzle body 11 with the nozzle 12 in motion, preferably in rotational movement, is added.

Die Bewegung des Düsenkörpers erfolgt hierbei in der Weise, dass der Düsenkörper entlang der konischen Innenfläche 15 des Gehäuses 7 um die Achse 23 rotiert, wobei der Düsenkörper 11 ferner eine Eigenrotation um seine Rotationsachse 22 durchführt.The movement of the nozzle body takes place here in such a way that the nozzle body rotates along the conical inner surface 15 of the housing 7 about the axis 23, wherein the nozzle body 11 also performs a self-rotation about its axis of rotation 22.

Über den Winkel _, der durch die Mittelachse 23 und die Rotationsachse 22 gebildet wird, lässt sich gemäß der vorliegenden Erfindung der Strahlkreis, der durch die rotierende Düse gebildet wird, in seiner Größe festlegen. So kann mit der Größe zum Beispiel der Anwendungsbereich als "Schmutzfräse" bestimmt werden, wobei hierdurch das Reinigen von größeren Flächen für den Bediener vereinfacht wird, da durch die Rotationsbewegung des Reinigungsstrahls die Bearbeitungsfläche vergrößert wird.Through the angle _ formed by the center axis 23 and the rotation axis 22, according to the present invention, the beam circle formed by the rotating nozzle can be determined in size. For example, size may be used to determine the scope of use as a "dirt tiller", thereby simplifying the cleaning of larger areas for the operator because of the Rotational movement of the cleaning jet, the processing surface is increased.

Der Düsenkörper 11 weist ferner eine Gleitfläche 21 auf, die gemäß der vorliegenden Erfindung als Kugelflächenabschnitt ausgebildet ist. Über diese Gleitfläche stützt sich der Düsenkörper auf dem Lager 9 ab, welches eine Lagerfläche 20 aufweist, die im wesentlichen auch einen kugelförmigen Oberflächenabschnitt bildet.The nozzle body 11 further has a sliding surface 21, which is formed according to the present invention as a spherical surface portion. About this sliding surface, the nozzle body is supported on the bearing 9, which has a bearing surface 20 which also forms a spherical surface portion substantially.

Gemäß eines besonders bevorzugten Ausführungsbeispiels können sich die Durchmesser der kugelförmigen Abschnitte der Gleitfläche und der Lagerfläche unterscheiden, wobei bevorzugt die Gleitfläche des Düsenkörpers etwas größer ausgeführt ist, als die Lagerfläche.According to a particularly preferred embodiment, the diameters of the spherical portions of the sliding surface and the bearing surface may differ, wherein preferably the sliding surface of the nozzle body is made slightly larger than the bearing surface.

Gemäß eines weiteren besonders bevorzugten Ausführungsbeispiels ist die Gleitfläche 21 als Konusöffnung mit einem Öffnungswinklel zwischen 110° und 150°, bevorzugt zwischen 120° und 140° ausgelegt.According to a further particularly preferred embodiment, the sliding surface 21 is designed as a cone opening with an opening angle between 110 ° and 150 °, preferably between 120 ° and 140 °.

Die Düse 12 mündet gemäß dem hier dargestellten Ausführungsbeispiel im Auslassbereich 8 des Düsengehäuses.The nozzle 12 opens according to the embodiment shown here in the outlet region 8 of the nozzle housing.

Der Düsenkörper weist gemäß dieses Ausführungsbeispiels einen wechselbaren Einsatz 16 auf, der bevorzugt aus einem anderen Material, als der des Düsenkörpers11 hergestellt ist. Hierdurch kann insbesondere der Bereich zwischen der Gleitfläche 21 und der Lagerfläche 20 so hergestellt werden, dass dieser den besonders hohen mechanischen Belastungen, welche durch die relativ hohe Differenzgeschwindigkeit zwischen der Gleitfläche und dem Lagerfläche im Betrieb besteht, besser standhält.The nozzle body according to this embodiment has a replaceable insert 16, which is preferably made of a different material than that of the nozzle body 11. In this way, in particular the region between the sliding surface 21 and the bearing surface 20 can be manufactured so that it better withstands the particularly high mechanical loads which exist due to the relatively high differential speed between the sliding surface and the bearing surface during operation.
