Description

Die Erfindung betrifft ein Hochdruckreinigungsgerät mit einem Gehäuse, in dem eine Pumpe und ein Antriebsmotor angeordnet sind, wobei von der Pumpe unter Druck gesetzte Flüssigkeit über einen Hochdruckschlauch abgebbar ist und der Hochdruckschlauch auf eine Schlauchtrommel aufwickelbar ist, die innerhalb des Gehäuses um eine Drehachse drehbar gelagert ist, und aus dem Gehäuse herausgeführt ist.The invention relates to a high-pressure cleaning device with a housing in which a pump and a drive motor are arranged, wherein the pump pressurized liquid can be delivered via a high-pressure hose and the high-pressure hose can be wound on a hose drum which is rotatably mounted within the housing about a rotational axis is, and led out of the case.

Aus der Gebrauchsmusterschrift DE 299 14 193 U1 ist ein Hochdruckreinigungsgerät bekannt, bei dem die Schlauchtrommel, auf die der Hochdruckschlauch aufgewickelt werden kann, außenseitig an einer Stirnseite des Gehäuses angeordnet ist. Über eine Schlauchführungseinrichtung kann der Hochdruckschlauch an einer Längsseite des Gehäuses von der Schlauchtrommel abgewickelt werden. Die Schlauchtrommel ist frei zugänglich. Es besteht deshalb die Gefahr, dass die Schlauchtrommel, insbesondere deren Lagerung, bei Einsatz des Hochdruckreinigungsgerätes beschädigt wird. Außerdem kann das Hochdruckreinigungsgerät nicht unmittelbar seitlich an einer Wand abgestellt werden, da seitlich neben dem Hochdruckreinigungsgerät ausreichend Platz vorhanden sein muss, um den Hochdruckschlauch von der Schlauchtrommel abzuwickeln.From the utility model DE 299 14 193 U1 a high-pressure cleaning device is known in which the hose reel, on which the high-pressure hose can be wound, is arranged on the outside at an end face of the housing. Via a hose guide device, the high-pressure hose can be unwound from the hose drum on a longitudinal side of the housing. The hose reel is freely accessible. There is therefore a risk that the hose reel, in particular their storage, is damaged when using the high-pressure cleaner. In addition, the high-pressure cleaning device can not be placed directly on the side of a wall, since there must be sufficient space next to the high-pressure cleaning device to unwind the high-pressure hose from the hose reel.

Aus der Offenlegungsschrift EP 0 770 575 A1 ist ein Hochdruckreinigungsgerät mit den Merkmalen des Oberbegriffes von Patentanspruch 1 bekannt. Bei diesem Gerät ist die Schlauchtrommel innerhalb des Gehäuses angeordnet und der Hochdruckschlauch über eine Öffnung aus dem Gehäuse herausgeführt. Mittels einer seitlich am Gehäuse gehaltenen Handkurbel kann der Hochdruckschlauch aufgewickelt werden. Die Drehachse der Schlauchtrommel ist parallel oder senkrecht zur Vertikalachse des Gehäuses ausgerichtet. Während des Betriebes des Hochdruckreinigungsgeräts nimmt das Gehäuse eine aufrechtstehende Lage ein, zum Verfahren kann es gekippt werden nach Art einer Sackkarre, wobei es eine verhältnismäßig lange Ausdehnung aufweist und deshalb vorsichtig verfahren werden muss.From the publication EP 0 770 575 A1 is a high-pressure cleaner with the features of the preamble of claim 1 is known. In this device, the hose drum is disposed within the housing and the high-pressure hose led out of the housing via an opening. By means of a hand crank held on the side of the housing, the high-pressure hose can be wound up. The axis of rotation of the hose reel is aligned parallel or perpendicular to the vertical axis of the housing. During operation of the high-pressure cleaning device, the housing assumes an upright position, for the process it can be tilted in the manner of a sack truck, wherein it has a relatively long extent and therefore must be moved carefully.

Aufgabe der vorliegenden Erfindung ist es, ein Hochdruckreinigungsgerät der eingangs genannten Art derart weiterzubilden, dass es eine kürzere Bauweise aufweist.Object of the present invention is to develop a high-pressure cleaning device of the type mentioned in such a way that it has a shorter design.

Diese Aufgabe wird durch ein Hochdruckreinigungsgerät mit den Merkmalen von Patentanspruch 1 gelöst.This object is achieved by a high-pressure cleaner with the features of claim 1.

Beim erfindungsgemäßen Hochdruckreinigungsgerät ist die Schlauchtrommel innerhalb des Gehäuses angeordnet und daher vor Beschädigungen geschützt. Es besteht praktisch keine Gefahr, dass die Schlauchtrommel, insbesondere deren Lagerung, während des Betriebes des Hochdruckreinigungsgerätes beschädigt wird. Von der Schlauchtrommel kann der Hochdruckschlauch an der Rückseite des Hochdruckreinigungsgerätes abgewickelt werden. Hierzu ist der Hochdruckschlauch rückseitig aus dem Gehäuse herausgeführt. Dies vereinfacht die Handhabung des Hochdruckreinigungsgerätes, insbesondere ist seitlich neben dem Hochdruckreinigungsgerät kein Platz erforderlich, um den Hochdruckschlauch auf- und abwickeln zu können.In the high-pressure cleaning device according to the invention, the hose reel is arranged within the housing and therefore protected from damage. There is virtually no risk that the hose reel, in particular their storage, will be damaged during operation of the high-pressure cleaning device. From the hose drum, the high-pressure hose can be unwound at the back of the high-pressure cleaner. For this purpose, the high-pressure hose is led out of the housing at the rear. This simplifies the handling of the high-pressure cleaning device, in particular no space is required laterally next to the high-pressure cleaning device in order to be able to wind up and unwind the high-pressure hose.

Die Drehachse der Schlauchtrommel ist parallel zur Horizontalachse des Gehäuses ausgerichtet ist. Dies erlaubt eine besonders kurze Bauweise des Gehäuses, so dass sich das erfindungsgemäße Hochdruckreinigungsgerät durch eine kompakte Bauform auszeichnet.The axis of rotation of the hose reel is aligned parallel to the horizontal axis of the housing. This allows a particularly short construction of the housing, so that the high-pressure cleaner according to the invention is characterized by a compact design.

Zum Aufwickeln des Hochdruckschlauches kann die Schlauchtrommel in Drehung versetzt werden. Bei einer bevorzugten Ausgestaltung der Erfindung ist hierzu an der Rückseite des Gehäuses eine Handkurbel drehbar gelagert. Günstig ist es, wenn die Drehachse der Handkurbel koaxial zur Drehachse der Schlauchtrommel ausgerichtet ist, insbesondere kann vorgesehen sein, dass die Handkurbel drehfest mit der Schlauchtrommel verbunden ist.To wind the high pressure hose, the hose reel can be rotated. In a preferred embodiment of the invention for this purpose a hand crank is rotatably mounted on the back of the housing. It is advantageous if the axis of rotation of the hand crank is aligned coaxially to the axis of rotation of the hose reel, in particular it can be provided that the hand crank is rotatably connected to the hose reel.

Eine besonders kurz -bauende Ausgestaltung des erfindungsgemäßen Hochdruckreinigungsgerätes zeichnet sich dadurch aus, dass die Handkurbel in einer rückseitigen Vertiefung des Gehäuses angeordnet ist. Dies hat den Vorteil, dass die Handkurbel allenfalls geringfügig über die Rückseite des Gehäuses hervorsteht, da sie größtenteils von der rückseitigen Vertiefung des Gehäuses aufgenommen ist.A particularly short construction of the high-pressure cleaning device according to the invention is characterized in that the hand crank is arranged in a rear recess of the housing. This has the advantage that the hand crank protrudes at most slightly above the back of the housing, since it is largely taken up by the rear recess of the housing.

Bei einer bevorzugten Ausgestaltung sind oberhalb der Vertiefung Bedienelemente des Hochdruckreinigungsgerätes angeordnet. Beispielsweise kann oberhalb der Vertiefung ein Schalter zum Ein- und Ausschalten des Antriebsmotors angeordnet sein, der die Pumpe antreibt. Auch Anzeigeelemente können oberhalb der Vertiefung angeordnet sein, beispielsweise eine Temperaturanzeige, falls das Hochdruckreinigungsgerät beheizbar ist. Die Anordnung von Bedienelementen oberhalb der die Handkurbel aufnehmenden Vertiefung an der Rückseite des Gehäuses vereinfacht die Handhabung des Hochdruckreinigungsgerätes, da die Bedienperson das Hochdruckreinigungsgerät an der Rückseite stehend bedienen kann.In a preferred embodiment, operating elements of the high-pressure cleaning device are arranged above the depression. For example, a switch for switching on and off the drive motor can be arranged above the depression, which drives the pump. Also display elements can be arranged above the recess, for example, a temperature display, if the high-pressure cleaning device is heated. The arrangement of controls above the handle receiving recess on the back of the housing simplifies the handling of the high-pressure cleaner, because the operator can operate the high-pressure cleaner standing at the back.

Von Vorteil ist es, wenn in der Vertiefung mindestens eine Einfüllöffnung zum Befüllen eines im Gehäuse angeordneten Vorratstankes angeordnet ist. Das Gehäuse kann beispielsweise einen Vorratstank für eine Reinigungschemikalie aufweisen, die der unter Druck gesetzten Flüssigkeit, vorzugsweise Wasser, beigemischt werden kann. Der Vorratstank kann über eine in der-Vertiefung angeordnete Einfüllöffnung befüllt werden. Dadurch vereinfacht sich die Handhabung des Hochdruckreinigungsgerätes.It is advantageous if at least one filling opening for filling a storage tank arranged in the housing is arranged in the recess. The housing may, for example, comprise a storage tank for a cleaning chemical which may be admixed with the pressurized liquid, preferably water. The storage tank can be filled via a filling opening arranged in the recess. This simplifies the handling of the high-pressure cleaner.

Es kann auch vorgesehen sein, dass neben der Vertiefung mindestens eine Einfüllöffnung zum Befüllen eines- im Gehäuse -angeordneten -Vorratstankes angeordnet ist, beispielsweise kann das Gehäuse einen Vorratstank für eine Entkalkungslösung aufweisen, der über eine seitlich neben der Vertiefung angeordnete Einfüllöffnung befüllt werden kann.It can also be provided that, in addition to the depression, at least one filling opening is arranged for filling a storage tank arranged in the housing, for example, the housing can have a storage tank for a descaling solution, which can be filled via a filling opening arranged laterally next to the depression.

Von besonderem Vorteil ist es, wenn die Vertiefung zwischen zwei Einfüllöffnungen angeordnet ist, über die jeweils ein Vorratstank befüllbar ist. Beispielsweise können an der Rückseite des Gehäuses, vorzugsweise jeweils in einem Eckbereich, zwei Einfüllöffnungen für Vorratstanks angeordnet sein, wobei die Vertiefung zwischen den beiden Einfüllöffnungen positioniert ist.It is particularly advantageous if the depression is arranged between two filling openings, via which a respective storage tank can be filled. For example, two filling openings for storage tanks can be arranged on the rear side of the housing, preferably in each case in a corner area, the depression being positioned between the two filling openings.

Das Hochdruckreinigungsgerät kann beheizbar ausgestaltet sein, indem die unter Druck gesetzte Flüssigkeit mittels eines Wärmetauschers aufgeheizt werden kann. Zum Betrieb des Wärmetauschers kann Brennstoff zum Einsatz kommen, der in einem Vorratstank innerhalb des Gehäuses bevorratet werden kann. Ein weiterer Vorratstank kann, wie bereits erläutert, eine Entkalkungslösung aufnehmen, wobei auch dieser Vorratstank über eine rückseitig am Gehäuse, nämlich seitlich neben der Vertiefung angeordnete Einfüllöffnung befüllt werden kann.The high-pressure cleaning device can be designed to be heatable by the pressurized liquid can be heated by means of a heat exchanger. For operation of the heat exchanger fuel can be used, which are stored in a storage tank within the housing can. As already explained, another storage tank can accommodate a descaling solution, wherein this storage tank can also be filled via a filling opening arranged on the rear side of the housing, namely laterally next to the recess.

Bei einer besonders bevorzugten Ausführungsform sind sämtliche Bedienelemente des Hochdruckreinigungsgerätes an der Rückseite des Gehäuses angeordnet. Dies erlaubt eine besonders einfache Handhabung des Hochdruckreinigungsgerätes.In a particularly preferred embodiment, all operating elements of the high-pressure cleaning device are arranged on the rear side of the housing. This allows a particularly simple handling of the high-pressure cleaning device.

Von Vorteil ist es, wenn im Gehäuse eine Schlauchführungseinrichtung angeordnet ist zum Führen des Hochdruckschlauches von der Schlauchtrommel zu einer rückseitigen Öffnung des Gehäuses. Mittels-der Schlauchführungseinrichtung kann der Hochdruckschlauch innerhalb des Gehäuses geführt werden. Dadurch ist sichergestellt, dass der Hochdruckschlauch auf einfache Weise an der Rückseite des Gehäuses aus dem Gehäuse herausgezogen und bei Bedarf wieder in das Gehäuse zurückgeführt werden kann. Eine unbeabsichtigte Schlaufenbildung beim Auf- oder Abwickeln des Hochdruckschlauches oder auch ein Verklemmen des Hochdruckschlauches kann dadurch vermieden werden.It is advantageous if a hose guide device is arranged in the housing for guiding the high-pressure hose from the hose reel to a rear opening of the housing. By means of the hose guide device, the high-pressure hose can be guided within the housing. This ensures that the high-pressure hose can be easily pulled out of the housing at the rear of the housing and returned to the housing as required. An unintentional looping when winding or unwinding the high pressure hose or jamming of the high pressure hose can be avoided.

Die Schlauchführungseinrichtung umfasst bei einer vorteilhaften Ausgestaltung mehrere im Abstand zueinander angeordnete Umlenkelemente. Es hat sich gezeigt, dass durch einen Satz von zueinander beabstandeten Umlenkelementen der Hochdruckschlauch auf einfache Weise auf- und abgewickelt werden kann. Zwischen einander benachbarten Umlenkelementen kann sich der Hochdruckschlauch entspannen, dies erleichtert das Auf- und Abwickeln. Günstig ist es, wenn zumindest ein Umlenkelement unterhalb der Schlauchtrommel angeordnet ist. Dies ermöglicht eine kompakte Bauform des Hochdruckreinigungsgerätes, wobei der Platzbedarf für die Schlauchtrommel und die Zuführung des Hochdruckschlauches gering gehalten werden können.The hose guide device comprises in an advantageous embodiment a plurality of mutually spaced deflection elements. It has been found that the high-pressure hose can be wound up and unwound in a simple manner by means of a set of deflection elements spaced apart from one another. Between adjacent deflecting the high-pressure hose can relax, this facilitates the winding and unwinding. It is favorable if at least one deflecting element is arranged below the hose drum. This allows a compact design of the high-pressure cleaning device, wherein the space required for the hose reel and the supply of the high-pressure hose can be kept low.

Es kann vorgesehen sein, dass die Schlauchtrommel einen zylindrischen Wickelkern und über dem Wickelkern radial vorstehende Seitenwangen aufweist und dass ausgehend von der Schlauchtrommel mindestens ein erstes Umlenkelement in einem Abstand zum Wickelkern angeordnet ist, der größer ist als der Wickelkerndurchmesser. Durch die Bereitstellung eines verhältnismäßig großen Abstandes zwischen dem Wickelkern und dem ersten Umlenkelement wird das Auf und Abwickeln des Hochdruckschlauches auf der Schlauchtrommel vereinfacht. Dies gilt insbesondere dann, wenn die Seitenwangen einen verhältnismäßig großen Abstand zueinander aufweisen. Der eher groß gewählte Abstand zwischen dem ersten Umlenkelement und dem Wickelkern ermöglicht eine zuverlässige Zuführung des Hochdruckschlauches zum Wickelkern, ohne dass die Gefahr besteht, dass der Hochdruckschlauch auf den Wickelkern ungleichmäßig aufgewickelt wird.It can be provided that the hose reel has a cylindrical winding core and radially projecting side cheeks above the winding core and that, starting from the hose reel, at least one first deflecting element is arranged at a distance from the winding core which is larger than the winding core diameter. By providing a relatively large distance between the winding core and the first deflecting the winding and unwinding of the high pressure hose on the hose reel is simplified. This is especially true when the side cheeks have a relatively large distance from each other. The rather large selected distance between the first deflecting element and the winding core allows reliable feeding of the high-pressure hose to the winding core, without the risk that the high-pressure hose is wound unevenly on the winding core.

Besonders günstig ist es, wenn der Abstand zwischen dem ersten Umlenkelement und dem Wickelkern mindestens das 1,5-fache des Wickelkerndurchmessers beträgt.It is particularly favorable if the distance between the first deflecting element and the winding core is at least 1.5 times the diameter of the winding core.

Das erste Umlenkelement ist bei einer vorteilhaften Ausgestaltung als Umlenkstange ausgestaltet, deren Länge mindestens dem gegenseitigen Abstand der Seitenwangen entspricht. Die Umlenkstange ist vorzugsweise frei drehbar gelagert, wobei die Drehachse der Umlenkstange parallel zur Drehachse der Schlauchtrommel ausgerichtet sein kann.The first deflecting element is designed in an advantageous embodiment as a deflecting bar whose length corresponds at least to the mutual distance of the side cheeks. The deflection bar is preferably freely rotatably mounted, wherein the axis of rotation of the deflection bar can be aligned parallel to the axis of rotation of the hose drum.

Bei einer besonders kompakt bauenden Ausgestaltung des erfindungsgemäßen Hochdruckreinigungsgerätes ist der Hochdruckschlauch am ersten Umlenkelement im Wesentlichen horizontal ausrichtbar. Beispielsweise kann der Hochdruckschlauch vom Wickelkern schräg zur Horizontalen ausgerichtet zum ersten Umlenkelement geführt werden und dort eine Umlenkung in eine Horizontalebene erfahren. Am ersten Umlenkelement ist der Hochdruckschlauch bei einer bevorzugten Ausgestaltung um mindestens 90° umlenkbar.In a particularly compact design of the high-pressure cleaning device according to the invention, the high-pressure hose can be aligned substantially horizontally on the first deflecting element. For example, the high-pressure hose can be guided by the winding core oriented obliquely to the horizontal to the first deflecting element and there experience a deflection in a horizontal plane. In the case of a preferred embodiment, the high-pressure hose can be deflected by at least 90 ° at the first deflecting element.

Mindestens ein zweites Umlenkelement ist bei einer bevorzugten Ausgestaltung in einem Abstand zum ersten Umlenkelement angeordnet, der mindestens dem Wickelkerndurchmesser entspricht. Dies ermöglicht eine Entspannung des Hochdruckschlauches zwischen dem ersten und dem zweiten Umlenkelement und dies wiederum erleichtert das Aufwickeln des Hochdruckschlauches auf der Schlauchtrommel.At least one second deflection element is arranged in a preferred embodiment at a distance from the first deflection element, which corresponds at least to the winding core diameter. This allows a relaxation of the high-pressure hose between the first and the second deflecting element and this in turn facilitates the winding of the high pressure hose on the hose reel.

Vorzugsweise beträgt der Abstand zwischen dem ersten und dem zweiten Umlenkelement mindestens das 1,5-fache des Wickelkerndurchmessers.Preferably, the distance between the first and the second deflecting element is at least 1.5 times the diameter of the winding core.

Von Vorteil ist es, wenn der Hochdruckschlauch am zweiten Umlenkelement im Wesentlichen parallel zur Horizontalachse des Gehäuses ausrichtbar ist. Dies ermöglicht es auf konstruktiv einfache Weise, den Hochdruckschlauch an der Rückseite des Gehäuses in einer Ausrichtung parallel zur Horizontalachse des Gehäuses auszugeben.It is advantageous if the high-pressure hose can be aligned on the second deflecting element substantially parallel to the horizontal axis of the housing. This makes it possible in a structurally simple way to output the high-pressure hose at the rear of the housing in an orientation parallel to the horizontal axis of the housing.

Das zweite Umlenkelement kann beispielsweise als frei drehbare Umlenkrolle ausgestaltet sein. Die Drehachse der Umlenkrolle ist bevorzugt vertikal ausgerichtet.The second deflection element can be designed, for example, as a freely rotatable deflection roller. The axis of rotation of the deflection roller is preferably aligned vertically.

Das zweite Umlenkelement kann mehrere frei drehbare Umlenkrollen aufweisen, die insgesamt eine Umlenkung des Hochdruckschlauches um einen Winkel von etwa 90° ermöglichen.The second deflecting element may have a plurality of freely rotatable deflection rollers, which allow a total of a deflection of the high-pressure hose at an angle of about 90 °.

In der Zeichnung ist schematisch ein beheizbares Hochdruckreinigungsgerät 10 dargestellt mit einem Gehäuse 12, das auf Hinterrädern 14 und Vorderrädern 15 verfahrbar gelagert ist und in üblicher Weise eine in der Zeichnung nicht dargestellte Pumpe, einen die Pumpe antreibenden Antriebsmotor sowie einen brennstoffbetriebenen Wärmetauscher aufnimmt. Derartige Pumpen, Antriebsmotoren und Wärmetauscher sind dem Fachmann bekannt, sie sind daher in der Zeichnung nicht dargestellt. Mittels der Pumpe kann eine Reinigungsflüssigkeit, vorzugsweise Wasser, unter Druck gesetzt werden, und mittels des Wärmetauschers kann die Reinigungsflüssigkeit aufgeheizt werden.In the drawing, a heated high-pressure cleaning device 10 is shown schematically with a housing 12 which is movably mounted on rear wheels 14 and front wheels 15 and accommodates in the usual way a pump not shown in the drawing, a drive motor driving the pump and a fuel-operated heat exchanger. Such pumps, drive motors and heat exchangers are known in the art, they are therefore not shown in the drawing. By means of the pump, a cleaning liquid, preferably water, can be pressurized, and by means of the heat exchanger, the cleaning liquid can be heated.

Zur Abgabe der unter Druck gesetzten Reinigungsflüssigkeit umfasst das Hochdruckreinigungsgerät 10 einen Hochdruckschlauch 17, der auf eine innerhalb des Gehäuses 12 im Bereich von dessen Rückseite 19 angeordnete Schlauchtrommel 21 aufgewickelt werden kann. Die Schlauchtrommel 21 ist um eine Drehachse 22 drehbar gelagert, die parallel zur horizontalen Längsachse (Horizontalchse) des Gehäuses 12 ausgerichtet ist.To deliver the pressurized cleaning liquid, the high-pressure cleaning device 10 comprises a high-pressure hose 17, which can be wound onto a hose reel 21 arranged within the housing 12 in the region of its rear side 19. The hose reel 21 is rotatably mounted about an axis of rotation 22 which is aligned parallel to the horizontal longitudinal axis (horizontal axis) of the housing 12.

Die Schlauchtrommel 21 umfasst einen zylindrischen Wickelkern 24 sowie zwei im Abstand zueinander angeordnete und über den Wickelkern radial vorstehende Seitenwangen, von denen in der Zeichnung nur eine Seitenwange 25 dargestellt ist. Die beiden Seitenwangen sind parallel zueinander ausgerichtet und jeweils in Form eines Gitters ausgebildet.The hose reel 21 comprises a cylindrical winding core 24 and two spaced-apart and over the winding core radially projecting side cheeks, of which only one side cheek 25 is shown in the drawing. The two side cheeks are aligned parallel to each other and each formed in the form of a grid.

Ein Ende des Hochdruckschlauches 17 taucht in den Wickelkern 24 ein und ist über eine an sich bekannte und deshalb in der Zeichnung im Detail nicht dargestellte stationäre Flüssigkeitskupplung in der Drehachse 22 der Schlauchtrommel 21 mit einer gehäusefesten Druckleitung verbunden, die an den Auslass der Pumpe angeschlossen ist. Über die Flüssigkeitskupplung ist in jeder Stellung der Schlauchtrommel 21 eine flüssigkeitsdichte Verbindung zwischen der Druckleitung und dem Hochdruckschlauch 17 sichergestellt.One end of the high-pressure hose 17 dips into the winding core 24 and is connected via a known per se and therefore not shown in detail in the drawing stationary fluid coupling in the axis of rotation 22 of the hose drum 21 with a housing-fixed pressure line, which is connected to the outlet of the pump , About the fluid coupling a liquid-tight connection between the pressure line and the high-pressure hose 17 is ensured in each position of the hose drum 21.

Die Schlauchtrommel 21 ist von einem Käfig 27 umgeben, der von mehreren, im Abstand zueinander angeordneten Stegen 28 gebildet wird, die jeweils parallel zur Drehachse 22 der Schlauchtrommel 21 ausgerichtet sind und über den Außenumfang der Seitenwangen 25 verteilt angeordnet sind. Mittels des Käfigs 27 ist sichergestellt, dass der Hochdruckschlauch 17 nicht unkontrolliert eine von der Schlauchtrommel 21 abstehende Schlaufe bilden kann.The hose drum 21 is surrounded by a cage 27 which is formed by a plurality of spaced-apart webs 28, each are aligned parallel to the axis of rotation 22 of the hose drum 21 and are arranged distributed over the outer circumference of the side cheeks 25. By means of the cage 27 it is ensured that the high-pressure hose 17 can not uncontrollably form a loop protruding from the hose drum 21.

Der Hochdruckschlauch 17 ist zwischen zwei Stege 28 radial nach außen geführt und trifft unterhalb der Schlauchtrommel 21 auf eine Schlauchführungseinrichtung 30 mit einem ersten Umlenkelement in Form einer Umlenkstange 32 und einem zweiten Umlenkelement in Form zweier Umlenkrollen 33, 34, zwischen denen der Hochdruckschlauch 17 hindurchgeführt ist. Die Umlenkstange 32 ist um eine parallel zur horizontalen Längsachse des Gehäuses 12 ausgerichtete Drehachse 36 frei drehbar, und die beiden Umlenkrollen 33, 34 sind über vertikal ausgerichtete Drehachsen 37, 38 frei drehbar. Mit einer Ausrichtung schräg zur Vertikalen wird der Hochdruckschlauch 17 vom Wickelkern 24 zur Umlenkstange 32 geführt. An der Umlenkstange 32 erfährt der Hochdruckschlauch 17 eine erste Umlenkung dergestalt, dass er anschließend im Wesentlichen horizontal ausgerichtet ist. In der vom Hochdruckschlauch 17 definierten Horizontalebene erfährt dieser dann an den Umlenkrollen 33, 34 eine weitere Umlenkung, so dass er anschließend parallel zur horizontalen Längsachse des Gehäuses 12 ausgerichtet ist und über eine Gehäuseöffnung 40, die an der Rückseite 19 des Gehäuses 12 angeordnet ist, aus dem Gehäuse 12 herausgezogen werden kann. An der Gehäuseöffnung 40 sind weitere Umlenkrollen 41, 42, 43 angeordnet, die jeweils frei drehbar gelagert sind. Die Drehachsen der Umlenkrollen 41 und 42 sind vertikal ausgerichtet und die Drehachse der Umlenkrolle 43 ist horizontal ausgerichtet. Der Hochdruckschlauch 17 ist zwischen die beiden Umlenkrollen 41 und 42 hindurchgeführt, und die Umlenkrolle 43 ist an der Gehäuseöffnung 40 über dem Hochdruckschlauch 17 angeordnet und überbrückt den Abstand zwischen den Umlenkrollen 41 und 42.The high-pressure hose 17 is guided radially outward between two webs 28 and strikes underneath the hose reel 21 a hose guide device 30 with a first deflecting element in the form of a deflecting rod 32 and a second deflecting element in the form of two deflecting rollers 33, 34, between which the high-pressure hose 17 is passed , The deflection bar 32 is freely rotatable about an axis of rotation 36 aligned parallel to the horizontal longitudinal axis of the housing 12, and the two deflection rollers 33, 34 are freely rotatable via vertically aligned axes of rotation 37, 38. With an orientation obliquely to the vertical of the high-pressure hose 17 is guided from the winding core 24 to the deflection bar 32. At the deflection bar 32, the high-pressure hose 17 undergoes a first deflection in such a way that it is subsequently aligned substantially horizontally. In the horizontal plane defined by the high-pressure hose 17, the latter then experiences a further deflection at the deflection rollers 33, 34, so that it is subsequently aligned parallel to the horizontal longitudinal axis of the housing 12 and via a housing opening 40 which is arranged on the rear side 19 of the housing 12. can be pulled out of the housing 12. At the housing opening 40 more pulleys 41, 42, 43 are arranged, which are each mounted freely rotatable. The axes of rotation of the guide rollers 41 and 42 are vertically aligned and the axis of rotation of the guide roller 43 is aligned horizontally. The high pressure hose 17 is passed between the two guide rollers 41 and 42, and the guide roller 43 is at the housing opening 40 above the high pressure hose 17 arranged and bridges the distance between the pulleys 41 and 42nd
