Description

Die Erfindung betrifft ein Hochdruckreinigungsgerät mit einem Rahmen, der eine Unterseite und eine Oberseite aufweist und einen Motor sowie eine von diesem angetriebenen Hochdruckpumpe trägt, und mit einer oberhalb von Pumpe und Motor am Rahmen gelagerten Aufnahme für einen einseitig mit dem Druckauslaß der Pumpe in Verbindung stehenden Hochdruckschlauch, der von der Aufnahme abziehbar ist.The invention relates to a high-pressure cleaner with a frame having a bottom and a top and carries a motor and a driven by this high-pressure pump, and with a mounted above the pump and motor on the frame receptacle for a one-sided with the pressure outlet of the pump in communication High-pressure hose, which is removable from the receptacle.

Bei Hochdruckreinigungsgeräten wird normalerweise ein relativ langer Hochdruckschlauch verwendet, damit der Benutzer vom Standpunkt des Hochdruckreinigungsgerätes aus unterschiedlich weit von diesem entfernte Reinigungsbereiche gut erreichen kann. Es ist dabei bekannt, den Hochdruckschlauch auf einer Aufnahme des Hochdruckreinigungsgerätes aufzunehmen, beispielsweise einer Schlauchtrommel, so daß der Benutzer bei Bedarf die gewünschte Länge des Hochdruckschlauches von dieser Aufnahme abzieht und sie wieder an die Aufnahme zurückgibt, also beispielsweise auf der Schlauchtrommel aufwickelt, wenn nur ein kürzerer Hochdruckschlauch benötigt wird.In high-pressure cleaning equipment, a relatively long high-pressure hose is normally used, so that the user can reach well from the point of view of the high-pressure cleaner at different distances from this remote cleaning areas. It is known to receive the high-pressure hose on a recording of the high-pressure cleaner, such as a hose drum, so that the user subtracts the desired length of the high-pressure hose from this recording if necessary and returns them to the recording, so for example wound on the hose reel, if only a shorter high pressure hose is needed.

Es sind Hochdruckreinigungsgeräte bekannt ( EP-A-0 904 855 ), bei denen an einem Rahmen im unteren Bereich die Pumpe, der Pumpenantrieb und eventuell andere Aggregate angeordnet sind, während eine Aufnahme für den Hochdruckschlauch oberhalb der Bauteile Platz findet. Es ergibt sich dann zwar eine relativ günstige und platzsparende Anordnung all dieser Teile, es besteht aber unter Umständen die Gefahr, daß der Benutzer beim Abziehen des Hochdruckschlauches ein so großes Drehmoment auf das Hochdruckreinigungsgerät ausübt, daß dieses umkippt. Je höher die Schlauchaufnahme beim Hochdruckreinigungsgerät angeordnet ist, desto größer wird diese Gefahr.High pressure cleaning devices are known ( EP-A-0 904 855 ), which are arranged on a frame in the lower area of the pump, the pump drive and possibly other units, while a receptacle for the high-pressure hose above the components takes place. Although this results in a relatively cheap and space-saving arrangement of all these parts, but there is a risk that the user exerts such a large torque on the high-pressure cleaner when pulling the high-pressure hose that this tilts. The higher the hose receiving the high-pressure cleaner is arranged, the greater this danger.

Das Dokument, EP-A-0 904 855 umfasst ein Hochdruckreinigungsgerät gemäss dem oberbegriff des Anspruchs 1. Es ist Aufgabe dieser Erfindung, ein gattungsgemäßes Hochdruckreinigungsgerät so auszubilden, daß auch beim Abziehen des Hochdruckschlauches dessen Standfestigkeit nicht beeinträchtigt wird.The document, EP-A-0 904 855 It is an object of this invention to design a generic high-pressure cleaning device so that even when removing the high-pressure hose whose stability is not affected.

Eine lösung für diese Aufgabe wird bereits in EP-A-0 770 575 vorgeschlagen.A solution for this task is already in EP-A-0 770 575 proposed.

Diese Aufgabe wird in der Erfindung bei einem Hochdruckreinigungsgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß am Rahmen an dessen Unterseite eine Abziehführung für den Hochdruckschlauch angeordnet ist und daß der Hochdruckschlauch am Rahmen von der Aufnahme zu der Abziehführung verläuft. Bei einer solchen Ausgestaltung ist sichergestellt, daß die Abziehkräfte, die über den Hochdruckschlauch auf das Hochdruckreinigungsgerät übertragen werden, im Bereich der Abziehführung auf das Hochdruckreinigungsgerät wirken, und da diese Abziehführung am unteren Ende des Hochdruckreinigungsgerätes angeordnet ist, werden also diese Kräfte am unteren Ende in das Hochdruckreinigungsgerät eingeleitet. Kippmomente werden dadurch fast vollständig vermieden.This object is achieved in the invention in a high-pressure cleaner of the type described above according to the invention that the frame on the underside of a Abziehführung is arranged for the high-pressure hose and that the high-pressure hose runs on the frame from the receptacle to the removal guide. In such an embodiment, it is ensured that the removal forces, which are transmitted via the high-pressure hose to the high-pressure cleaner, in the Abziehführung act on the high-pressure cleaner, and since this Abziehführung is located at the lower end of the high-pressure cleaner, so these forces at the lower end in initiated the high pressure cleaning device. Tipping moments are thereby almost completely avoided.

Die Aufnahme kann unterschiedlich ausgebildet sein, besonders vorteilhaft ist die Verwendung einer drehbaren Trommel, vorzugsweise kann diese Trommel auch federbelastet sein, so daß beim Verkürzen des Hochdruckschlauches dieser selbsttätig auf die Trommel aufgewickelt wird.The receptacle can be designed differently, particularly advantageous is the use of a rotatable drum, preferably this drum can also be spring loaded, so that when shortening the high pressure hose this is automatically wound onto the drum.

Besonders günstig ist es, wenn die Abziehführung an einer unteren Außenkante des Rahmens angeordnet ist.It is particularly favorable if the removal guide is arranged on a lower outer edge of the frame.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß der Hochdruckschlauch an der Unterseite des Rahmens vor der Abziehführung längs der Unterseite des Rahmens geführt ist, insbesondere verläuft der Hochdruckschlauch an der Unterseite des Rahmens über dessen gesamte Ausdehnung von einer Seite des Rahmens bis zur gegenüberliegenden Seite.In a preferred embodiment it is provided that the high-pressure hose is guided on the underside of the frame in front of the removal guide along the underside of the frame, in particular the high-pressure hose runs on the underside of the frame over its entire extent from one side of the frame to the opposite side.

Es ist weiterhin vorteilhaft, wenn der Hochdruckschlauch von der Aufnahme zur Unterseite des Rahmens neben dem Rahmen verläuft. Dadurch ist im Bereich des Rahmens ausreichend Platz zur Aufnahme aller notwendigen Aggregate, der seitlich am Rahmen vorbeigeführte Hochdruckschlauch hat einen sehr geringen Platzbedarf, und dieser Verlauf an der Außenseite des Rahmens gibt dem Konstrukteur die Möglichkeit, im Inneren des Rahmens die notwendigen Bauteile ohne Rücksicht auf den Verlauf des Hochdruckschlauches unterzubringen.It is also advantageous if the high-pressure hose extends from the receptacle to the underside of the frame next to the frame. As a result, in the area of the frame there is sufficient space for accommodating all the necessary aggregates, the high-pressure hose routed past the frame has a very small space requirement, and this course on the outside of the frame gives the designer the opportunity to install the necessary components in the interior of the frame irrespective of to accommodate the course of the high pressure hose.

Besonders vorteilhaft ist es, wenn der Rahmen einen Rücksprung aufweist, durch den der Hochdruckschlauch hindurchläuft. Dieser Rücksprung schützt den Hochdruckschlauch gegen Beschädigung oder gegen ungewollte Berührung durch den Benutzer.It is particularly advantageous if the frame has a recess through which the high-pressure hose passes. This return protects the high pressure hose against damage or accidental contact by the user.

Beispielsweise kann der Rücksprung als sich über eine Seitenfläche des Rahmens erstreckende Nut ausgebildet sein.For example, the recess may be formed as extending over a side surface of the frame groove.

Dabei ist es günstig, wenn die Nut sich zur Unterseite des Rahmens hin verengt, insbesondere V-förmig. Die Seitenwände der Nut bilden dann eine Führung für den Hochdruckschlauch, die diesem ermöglichen, beim Aufwickeln auf die Aufnahme quer zu deren Drehachse zu wandern und sich so in nebeneinander liegenden Lagen auf der Aufnahme abzulegen. An der gegenüberliegenden Seite dagegen bildet die sich verengende Nut eine Führung für den Hochdruckschlauch, beispielsweise führt diese Nut den Hochdruckschlauch bei einer zentralen Anordnung in der Mittelebene des Hochdruckreinigungsgerätes.It is advantageous if the groove narrows towards the underside of the frame, in particular V-shaped. The side walls of the groove then form a guide for the high-pressure hose, which allow it to migrate when winding on the recording transversely to the axis of rotation and thus deposit in adjacent layers on the recording. On the opposite side, however, the narrowing groove forms a guide for the high-pressure hose, for example, this groove leads the high-pressure hose in a central arrangement in the center plane of the high-pressure cleaner.

Zusätzlich kann vorgesehen sein, daß der Rücksprung zumindest teilweise nach außen hin abgedeckt ist, dadurch wird der Schutz noch erhöht.In addition, it can be provided that the return is at least partially covered to the outside, thereby the protection is increased.

Günstig ist es, wenn mindestens eine zweite Führung für den Hochdruckschlauch zwischen der Aufnahme und der Abziehführung angeordnet ist.It is advantageous if at least one second guide is arranged for the high-pressure hose between the receptacle and the removal guide.

Diese weitere Führung kann insbesondere als Umlenkführung ausgebildet sein, die den von oben nach unten verlaufenden Teil des Hochdruckschlauches in einen längs der Unterseite des Rahmens verlaufenden Abschnitt umlenkt.This further guide can be designed, in particular, as a deflecting guide, which deflects the part of the high-pressure hose extending from top to bottom into a section extending along the underside of the frame.

Günstig ist es, wenn die Umlenkführung an einer unteren Außenkante des Rahmens angeordnet ist.It is advantageous if the deflecting guide is arranged on a lower outer edge of the frame.

Bei einer bevorzugten Ausführungsform der Erfindung ist mindestens eine weitere als Stützfläche wirkende Stützführung zwischen der Abziehführung und der Umlenkführung angeordnet. Diese Stützführung kann beispielsweise als drehbare Rolle oder Walze ausgebildet sein.In a preferred embodiment of the invention, at least one further supporting guide acting as a supporting surface is arranged between the peeling guide and the deflecting guide. This support guide may be formed, for example, as a rotatable roller or roller.

Die Abziehführung kann gemäß einer bevorzugten Ausführungsform der Erfindung eine Durchtrittsöffnung für den Hochdruckschlauch aufweisen, die seitlich durch Führungsflächen begrenzt ist. Dabei ist es vorteilhaft, wenn mindestens eine Führungsfläche durch eine drehbare Führungsrolle begrenzt wird. Es können mehrere derartige Führungsrollen vorgesehen sein, deren Drehachsen gegeneinander geneigt sind, vorzugsweise verlaufen bei mindestens zwei der Führungsrollen die Drehachsen quer zueinander.The removal guide can according to a preferred embodiment of the invention have a passage opening for the high-pressure hose, which is bounded laterally by guide surfaces. It is advantageous if at least one guide surface is limited by a rotatable guide roller. There may be provided a plurality of such guide rollers whose axes of rotation are inclined relative to each other, preferably extend at least two of the guide rollers, the axes of rotation transversely to each other.

Der Rahmen kann sehr unterschiedlich ausgebildet sein, unter "Rahmen" wird bei der Erfindung jede Vorrichtung verstanden, die die Pumpe und den Motor und gegebenenfalls weitere technische Aggregate im Betrieb des Hochdruckreinigungsgerätes aufnimmt, dabei kann es sich um ein einfaches Rahmengestell handeln, um ein teilweise oder ganz geschlossenes Gehäuse, um ein Kunststofformteil mit integrierten Flüssigkeitstanks etc.The frame can be designed very differently, "frame" is understood in the invention, any device that receives the pump and the motor and possibly other technical units in operation of the high-pressure cleaner, it may be a simple frame to a partial or completely closed housing to a plastic molding with integrated liquid tanks etc.

Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, daß der Rahmen ein Gehäuse umfaßt, das den Motor und die Pumpe aufnimmt, und daß der Hochdruckschlauch längs einer Seitenwand und längs der Unterseite des Gehäuses zur Abziehführung verläuft.In a particularly preferred embodiment it is provided that the frame comprises a housing which houses the motor and the pump, and that the high-pressure hose along a side wall and along the underside of the housing extends to Abziehführung.

Dabei ist es vorteilhaft, wenn die Aufnahme oberhalb des Gehäuses angeordnet ist.It is advantageous if the receptacle is arranged above the housing.

Insbesondere kann die Aufnahme von einem mit dem Rahmen verbundenen Handgriff umgeben werden, der beispielsweise an das Gehäuse angeformt ist und U-förmig ausgebildet ist, auf diese Weise erhält man eine optimale Platzausnützung zur Aufnahme der unterschiedlichen Bauteile.In particular, the receptacle can be surrounded by a handle connected to the frame, which is formed, for example, to the housing and U-shaped, in this way one obtains optimal space utilization for receiving the different components.

Das in der Zeichnung dargestellte Hochdruckreinigungsgerät 1 umfaßt ein im wesentlichen quaderförmiges geschlossenes Gehäuse 2, welches in seinem Inneren einen Motor und eine Pumpe sowie weitere technische Aggregate aufweist, die dazu nötig sind, um eine Reinigungsflüssigkeit, beispielsweise Wasser, von einer Versorgungsleitung auf hohen Druck zu bringen und dann einer Hochdruckleitung zuzuführen. Diese Aggregate sind in der Zeichnung nur schematisch angedeutet und pauschal mit dem Bezugszeichen 3 versehen.The high-pressure cleaner 1 shown in the drawing comprises a substantially cuboid closed housing 2, which has in its interior a motor and a pump and other technical units, which are necessary to a cleaning fluid, such as water, from a supply line to high pressure bring and then supply a high pressure line. These units are indicated only schematically in the drawing and provided with the reference numeral 3.

Das Gehäuse 2 weist eine im wesentlichen ebene Unterseite 4 auf sowie eine etwa senkrecht davon abgehende Vorderseite 5 und eine ebenfalls etwa senkrecht davon abgehende Rückseite 6, die über eine Oberseite 7 miteinander verbunden sind, die etwa parallel zur Unterseite 4 verläuft. Im Übergangsbereich zwischen der Vorderseite 5 und der Unterseite 4 ist eine Vorderkante 8 ausgebildet, im Übergangsbereich zwischen der Rückseite 6 und der Unterseite 4 eine Rückkante 9.The housing 2 has a substantially flat underside 4 and a front side 5 extending approximately perpendicularly therefrom and a rear side 6 which also extends approximately perpendicularly therefrom and which are interconnected via an upper side 7 which runs approximately parallel to the underside 4. In the transition region between the front 5 and the bottom 4, a front edge 8 is formed, in the transition region between the back 6 and the bottom 4, a rear edge. 9

Im Bereich dieser Rückkante 9 sind am Gehäuse 2 zwei Räder 10 um eine parallel zur Rückkante 9 verlaufende Drehachse drehbar gelagert, im Bereich der Vorderkante 8 befinden sich am Gehäuse 2 in der Zeichnung nicht näher dargestellte Stützen, so daß das Gehäuse 2 normalerweise auf diesen Stützen und den Rädern 10 auf einer Stellfläche ruht.In the area of this rear edge 9, two wheels 10 are mounted rotatably about a parallel to the rear edge 9 extending axis of rotation on the housing 2, in the region of the front edge 8 are on the housing 2 in the drawing not shown supports, so that the housing 2 normally on these supports and the wheels 10 rests on a footprint.

An die Oberseite 7 des Gehäuses 2 schließt sich ein U-förmiger Handgriff 11 an mit einem parallel zur Oberseite 7 verlaufenden Griffsteg 12 und zwei quer dazu verlaufenden, in das Gehäuse 2 einmündenden seitlichen Holmen 13, 14. Mit Hilfe dieses Handgriffes 11 kann das Hochdruckreinigungsgerät 1 mittels der Räder 10 verfahren werden.At the top 7 of the housing 2, a U-shaped handle 11 connects with a parallel to the top 7 extending grip web 12 and two transverse thereto, opening into the housing 2 side rails 13, 14. With the help of this handle 11, the high-pressure cleaning device 1 are moved by means of the wheels 10.

Der Handgriff 11 bildet oberhalb des Gehäuses 2 zwischen dem Griffsteg 12 und den beiden Holmen 13, 14 einen Aufnahmeraum aus, in dem zwischen den beiden Holmen 13 und 14 eine Schlauchtrommel 15 gelagert ist, diese ist um ihre Längsachse verdrehbar, diese Längsachse läuft parallel zum Griffsteg 12. Auf diese Schlauchtrommel 15 ist ein flexibler Hochdruckschlauch 16 aufgewickelt, dessen auf die Schlauchtrommel 15 aufgewickeltes Ende in aus der Zeichnung nicht ersichtlicher Weise mit dem Druckauslaß der Hochdruckpumpe im Inneren des Gehäuses 2 in Verbindung steht. Dazu sind dem Fachmann die notwendigen Verbindungsmittel bekannt, beispielsweise wird eine Lagerwelle der Schlauchtrommel 15 als Zuleitung für die von der Pumpe zum Hochdruckschlauch geförderte Flüssigkeit verwendet.The handle 11 forms above the housing 2 between the handle bar 12 and the two bars 13, 14 a receiving space in which between the two bars 13 and 14 a hose drum 15 is mounted, this is rotatable about its longitudinal axis, this longitudinal axis runs parallel to On this hose reel 15, a flexible high-pressure hose 16 is wound, the end wound on the hose reel 15 in the manner not apparent from the drawing with the pressure outlet of the high-pressure pump in the interior of the housing 2 is in communication. For this purpose, the person skilled in the necessary connection means are known, for example, a bearing shaft of the hose drum 15 is used as a supply line for the pumped from the pump to the high-pressure hose liquid.

Von der Umfangsfläche 17 der Schlauchtrommel 15 verläuft der Hochdruckschlauch 16 parallel zur Rückseite 6 des Gehäuses 2 in geringfügigem Abstand von dieser Rückseite 6 bis in den Bereich der Rückkante 9 und von dort unmittelbar an der Unterseite 4 des Gehäuses 2 entlang bis zur Vorderkante 8.From the circumferential surface 17 of the hose reel 15, the high-pressure hose 16 runs parallel to the rear side 6 of the housing 2 at a slight distance from this rear side 6 into the region of the rear edge 9 and from there directly to the underside 4 of the housing 2 along the front edge 8.

Im Bereich der Vorderkante 8 ist in deren Mitte eine Abziehführung 18 angeordnet, durch die der Hochdruckschlauch 16 hindurchläuft und die den Hochdruckschlauch quer zu seiner Längsrichtung durch eine definierte Durchtrittsöffnung hindurchführt, deren Querschnitt nur geringfügig größer ist als der Querschnitt des Hochdruckschlauches 16. Ein Beispiel einer solchen Abziehführung 18 ist in Figur 5 dargestellt. In einem rechteckigen Rahmen 19 sind drei Führungsrollen 20, 21, 22 um jeweils senkrecht aufeinanderstehende, parallel zu den Seiten des Rahmens 19 verlaufende Drehachsen verdrehbar gelagert, diese bilden zwischen sich die Durchtrittsöffnung 23 aus, die an der vierten Seite durch den Rahmen 19 selbst begrenzt wird.In the area of the front edge 8, a removal guide 18 is arranged in the middle, through which the high-pressure hose 16 passes and which passes the high-pressure hose transversely to its longitudinal direction through a defined passage opening whose cross-section is only slightly larger than the cross-section of the high-pressure hose 16. An example of Such Abziehführung 18 is in FIG. 5 shown. In a rectangular frame 19, three guide rollers 20, 21, 22 rotatably mounted about mutually perpendicular, parallel to the sides of the frame 19 extending axes of rotation, these form between them the passage opening 23, which limits on the fourth side by the frame 19 itself becomes.

Im Bereich der Rückkante 9 ist ebenfalls in deren Mitte eine Umlenkrolle 23 angeordnet, die den Hochdruckschlauch von der Senkrechten in die Horizontale umlenkt, und zwischen dieser Umlenkrolle 23 und der Abziehführung 18 ist etwa in der Mitte der Unterseite 4 noch eine Stützrolle 24 angeordnet, an welcher der Hochdruckschlauch 16 anliegt.In the area of the rear edge 9, a guide roller 23 is also arranged in the middle, which deflects the high pressure hose from the vertical to the horizontal, and between this guide roller 23 and the Abziehführung 18 is approximately in the middle of the bottom 4 is still a support roller 24 is arranged at which the high-pressure hose 16 abuts.

Die Rückseite 6 des Gehäuses 2 weist eine von oben nach unten durchlaufende, in der Mitte angeordnete Längsnut 25 auf, die sich V-förmig von oben nach unten verengt und die im Bereich der Rückkante 9 so schmal ist, daß der Hochdruckschlauch 16 gegen eine seitliche Verschiebung in der Mitte der Rückkante geführt und dort direkt der Umlenkrolle 23 zugeführt wird. Durch die V-förmige Aufweitung erlaubt die Längsnut 25 dem Hochdruckschlauch 16 dagegen am oberen Ende der Längsnut eine seitliche Bewegung, so daß der Hochdruckschlauch sich über die gesamte Breite der Schlauchtrommel 15 bewegen und lagenweise auf der Umfangsfläche 17 ablegen kann.The back 6 of the housing 2 has a continuous from top to bottom, arranged in the middle longitudinal groove 25 which narrows V-shaped from top to bottom and which is so narrow in the region of the rear edge 9, that the high-pressure hose 16 against a lateral Guided displacement in the middle of the rear edge and there directly to the guide roller 23 is supplied. By virtue of the V-shaped widening, the longitudinal groove 25 permits the high-pressure hose 16 to move laterally at the upper end of the longitudinal groove, so that the high-pressure hose can move over the entire width of the hose reel 15 and deposit it in layers on the peripheral surface 17.

Durch die beschriebene Führung des Hochdruckschlauches 16 am Hochdruckreinigungsgerät 1 werden beim Abziehen des Hochdruckschlauches 16 die dadurch entstehenden Kräfte im Bereich der Abziehführung 18 in das Hochdruckreinigungsgerät 1 eingeleitet, also an dem unteren Ende des Hochdruckreinigungsgerätes 1 und außerdem in der Mitte der Vorderkante. Es wird dadurch praktisch kein Kippmoment auf das Hochdruckreinigungsgerät ausgeübt, und trotzdem ist es möglich, die Schlauchtrommel 15 in großem Abstand von der Unterseite des Hochdruckreinigungsgerätes 1 an diesem zu lagern und dadurch eine sehr kompakte Anordnung aller gewünschten Teile des Hochdruckreinigungsgerätes zu erreichen.As a result of the described guidance of the high-pressure hose 16 on the high-pressure cleaning device 1, the resulting forces in the region of the removal guide 18 are introduced into the high-pressure cleaning device 1 when the high-pressure hose 16 is removed, ie at the lower end of the high-pressure cleaning device 1 and also in the middle of the leading edge. It is practiced practically no tilting moment on the high-pressure cleaner, and yet it is possible to store the hose drum 15 at a great distance from the bottom of the high-pressure cleaner 1 at this and thereby achieve a very compact arrangement of all desired parts of the high-pressure cleaner.

Der Hochdruckschlauch 16 wird um das Gehäuse 2 auf definierten Wegen herumgeführt und ist dabei auch im Bereich des Hochdruckreinigungsgerätes 1 über seinen gesamten Verlauf geschützt, gegebenenfalls können auch Abdekkungen vorgesehen sein, um diesen Schutz noch zu verbessern.The high-pressure hose 16 is guided around the housing 2 on defined paths and is also protected in the area of the high-pressure cleaning device 1 over its entire course, if necessary, also covers can be provided to improve this protection.
