Description

Die Erfindung betrifft ein Hochdruckreinigungsgerät mit einer Motorpumpeneinheit, die zumindest teilweise von einem Gehäuse umgeben ist und die einen Motor sowie eine vom Motor angetriebene Pumpe für eine Reinigungsflüssigkeit aufweist, und mit einem an die Pumpe angeschlossenen Saugschlauch für ein der Reinigungsflüssigkeit beimischbares Reinigungsmittel, das der Pumpe über den Saugschlauch zuführbar ist.The invention relates to a high-pressure cleaning device with a motor pump unit which is at least partially surrounded by a housing and having a motor and a pump driven by the motor for a cleaning liquid, and with a connected to the pump suction hose for a cleaning liquid which can be added to the cleaning liquid, that of the pump can be fed via the suction hose.

Mittels derartiger Hochdruckreinigungsgeräte kann eine Reinigungsflüssigkeit, vorzugsweise Wasser, unter Druck gesetzt und auf eine zu reinigende Fläche gerichtet werden. Die Reinigungsflüssigkeit kann der Pumpe des Hochdruckreinigungsgeräts über eine Flüssigkeitszufuhrleitung zugeführt werden, und die von der Pumpe unter Druck gesetzte Reinigungsflüssigkeit kann über eine Flüssigkeitsabgabeleitung, beispielsweise einen Hochdruckschlauch abgegeben werden. Am freien Ende der Flüssigkeitsabgabeleitung ist üblicherweise eine Sprühlanze oder eine Sprühpistole angeordnet.By means of such high-pressure cleaning devices, a cleaning liquid, preferably water, can be pressurized and directed to a surface to be cleaned. The cleaning liquid may be supplied to the pump of the high-pressure cleaner via a liquid supply pipe, and the cleaning liquid pressurized by the pump may be discharged through a liquid discharge pipe such as a high-pressure hose. At the free end of the liquid discharge line usually a spray lance or a spray gun is arranged.

Zur Erhöhung der Reinigungswirkung kann der Reinigungsflüssigkeit ein flüssiges Reinigungsmittel beigemischt werden. Das Reinigungsmittel kann der Pumpe über einen Saugschlauch zugeführt werden. Der Saugschlauch ist an die Pumpe angeschlossen. Hierzu kann ein erstes Ende des Saugschlauchs unmittelbar mit einem Pumpengehäuse verbunden sein, es kann allerdings auch vorgesehen sein, dass das erste Ende des Saugschlauchs an eine Saugleitung angeschlossen ist, die mit einem Saugeinlass der Pumpe in Strömungsverbindung steht. An ein der Pumpe abgewandtes zweites Ende des Saugschlauchs, das nachfolgend als "freies Ende des Saugschlauchs" bezeichnet wird, kann ein mit flüssigem Reinigungsmittel befüllter Reinigungsmittelbehälter angeschlossen werden. Aus dem Reinigungsmittelbehälter kann dann von der Pumpe Reinigungsmittel abgesaugt und der Reinigungsflüssigkeit beigemischt werden.To increase the cleaning effect of the cleaning liquid, a liquid detergent can be added. The cleaning agent can be supplied to the pump via a suction hose. The suction hose is connected to the pump. For this purpose, a first end of the suction hose can be connected directly to a pump housing, but it can also be provided that the first end of the suction hose is connected to a suction line, which is in flow communication with a suction inlet of the pump. At one of the pump remote from the second end of the suction hose, which is hereinafter referred to as "free end of the suction hose", a filled with liquid detergent detergent container can be connected. Cleaning agent can then be sucked out of the detergent container by the pump and mixed with the cleaning liquid.

Aus der Veröffentlichung EP 0 904 856 B1 ist ein Hochdruckreinigungsgerät bekannt, bei dem ein Reinigungsmittelbehälter in das Hochdruckreinigungsgerät integriert ist. In vielen Fällen wird jedoch bereits ohne Beimischung eines flüssigen Reinigungsmittels eine sehr gute Reinigungswirkung erzielt, so dass der Einsatz eines Reinigungsmittels nicht permanent erforderlich ist. In der Veröffentlichung DE 91 17 199 U1 wird für den Einsatz eines Reinigungsmittels ein Zusatzbehälter vorgeschlagen, der das Reinigungsmittel aufnimmt und der am Gehäuse des Hochdruckreinigungsgeräts positioniert werden kann. Der Zusatzbehälter wird dann über den Saugschlauch mit der Pumpe verbunden.From the publication EP 0 904 856 B1 a high pressure cleaning device is known in which a detergent container is integrated into the high pressure cleaning device. In many cases, however, a very good cleaning effect is achieved even without admixing a liquid cleaning agent, so that the use of a cleaning agent is not permanently required. In the publication DE 91 17 199 U1 For the use of a cleaning agent, an additional container is proposed, which receives the cleaning agent and can be positioned on the housing of the high-pressure cleaner. The additional container is then connected via the suction hose to the pump.

Ist die Beimischung eines Reinigungsmittels zur Lösung einer konkreten Reinigungsaufgabe nicht erforderlich, so kann der Reinigungsmittelbehälter vom feien Ende des Saugschlauchs getrennt werden und der über sein erstes Ende mit der Pumpe verbundene Saugschlauch kann am Hochdruckreinigungsgerät verstaut werden. Es ist denkbar, den Saugschlauch mit seinem freien Ende an einer vom Gehäuse abstehenden Schlauchhalterung zu fixieren. Hierbei besteht allerdings die Gefahr einer Beschädigung des Saugschlauchs und/oder der Schlauchhalterung. Die Gefahr einer Beschädigung besteht insbesondere in Fällen, in denen am freien Ende des Saugschlauchs ein Filterelement angeordnet ist, mit dessen Hilfe das der Pumpe zuführbare Reinigungsmittel gefiltert werden kann.If the admixture of a cleaning agent to solve a specific cleaning task is not required, then the detergent container from the fine end of the suction hose can be separated and connected via its first end to the pump suction hose can be stowed on the high-pressure cleaner. It is conceivable to fix the suction hose with its free end to a hose holder projecting from the housing. However, there is the risk of damage to the suction hose and / or the hose holder. The risk of damage exists in particular in cases in which a filter element is arranged at the free end of the suction hose, with the help of which the pump can be fed to the cleaning agent can be filtered.

Aus dem Dokument EP 0 504 568 A1 ist ein Hochdruckreinigungsgerät bekannt, dessen Gehäuse ein Fach aufweist, das von einem Deckel verschließbar ist und in dem ein Behälter angeordnet ist. In den Behälter taucht ein Saugschlauch ein, der an seinem freien Ende innerhalb des Behälters ein Sieb oder Filter trägt. Der Saugschlauch ist durch einen Deckel des Behälters hindurchgeführt und erstreckt sich bis zu einem Injektor, in dem ein Unterdruck erzeugt wird. Eine im Behälter befindliche Chemikalie kann über den Saugschlauch angesaugt und einer Pumpe des Hochdruckreinigungsgeräts zugeführt werden.From the document EP 0 504 568 A1 a high-pressure cleaning device is known, the housing has a compartment which can be closed by a lid and in which a container is arranged. In the container immersed a suction hose, which carries at its free end within the container a sieve or filter. The suction hose is passed through a lid of the container and extends to an injector, in which a negative pressure is generated. A chemical contained in the container can be sucked in via the suction hose and fed to a pump of the high-pressure cleaning device.

Das Schlauchfach ist von einem Schlauchfachabdeckelement abgedeckt, so dass der im Schlauchfach deponierte Saugschlauch vor Beschädigungen geschützt ist. Das Schlauchfachabdeckelement weist eine Durchgangsöffnung auf, durch die hindurch der Saugschlauch aus dem Schlauchfach herausgezogen werden kann in Fällen, in denen der Reinigungsflüssigkeit ein flüssiges Reinigungsmittel beigemischt werden soll, das der Pumpe über den Saugschlauch zugeführt wird. Nach erfolgtem Einsatz des Saugschlauchs kann dieser über die Durchgangsöffnung des Schlauchfachabdeckelements in das Schlauchfach zurückgeführt werden. Damit der Saugschlauch dem Benutzer auf einfache Weise zugänglich ist, ist das freie Ende des Saugschlauchs, das heißt das der Pumpe abgewandte Ende des Saugschlauchs an dem Schlauchfachabdeckelement positionierbar, insbesondere lösbar fixierbar. Alternativ kann vorgesehen sein, dass am freien Ende des Saugschlauchs ein Filterelement angeordnet ist.

The Schlauchfachabdeckelement thus gives the user the ability to take the free end of the suction hose or arranged at the free end of the suction hose filter element, then to pull the suction hose out of the hose compartment.

Das der Pumpe zugewandte erste Ende des Saugschlauchs kann permanent mit der Pumpe verbunden bleiben, eine vollständige Trennung des Saugschlauchs von der Pumpe in Fällen, in denen der Reinigungsflüssigkeit kein Reinigungsmittel beigemischt werden soll, ist nicht erforderlich.The pump facing the first end of the suction hose can remain permanently connected to the pump, a complete separation of the suction hose from the pump in cases where the cleaning liquid no detergent is to be added, is not required.

Das Schlauchfachabdeckelement kann am Gehäuse des Hochdruckreinigungsgeräts lösbar oder unlösbar gehalten sein. Beispielsweise kann vorgesehen sein, dass das Schlauchfachabdeckelement mit dem Gehäuse lösbar oder unlösbar verrastbar ist.The Schlauchfachabdeckelement can be releasably or permanently held on the housing of the high-pressure cleaning device. For example, it can be provided that the Schlauchfachabdeckelement with the housing is releasably or permanently locked.

Das Gehäuse bildet bei einer vorteilhaften Ausführungsform der Erfindung eine Rückwand des Schlauchfachs sowie das Schlauchfach in Umfangsrichtung umgebende Seitenwände, und das Schlauchfachabdeckelement ist auf der der Rückwand abgewandten Seite des Schlauchfachs am Gehäuse gehalten.The housing forms in an advantageous embodiment of the invention, a rear wall of the hose compartment and the hose compartment circumferentially surrounding side walls, and the Schlauchfachabdeckelement is held on the side facing away from the rear wall of the hose compartment on the housing.

Die beiden Ausnehmungen erleichtern es dem Benutzer, das freie Ende des Saugschlauchs oder das am freien Ende des Saugschlauchs angeordnete Filterelement beispielsweise mit Daumen und Zeigefinger zu ergreifen.The two recesses make it easier for the user to grasp the free end of the suction hose or the filter element arranged at the free end of the suction hose, for example with the thumb and forefinger.

Günstigerweise liegen die beiden Ausnehmungen des Halteteils einander gegenüber.Conveniently, the two recesses of the holding part are opposite each other.

Das Halteteil ist günstigerweise als Hülse ausgestaltet, in die das freie Ende des Saugschlauchs oder ein am freien Ende des Saugschlauchs angeordnetes Filterelement einsetzbar ist und das zwei einander diametral gegenüberliegende Ausnehmungen aufweist.The holding part is conveniently designed as a sleeve into which the free end of the suction hose or a filter element arranged at the free end of the suction hose can be inserted and which has two diametrically opposite recesses.

Die Hülse ist günstigerweise zylinderförmig ausgestaltet, denn dies erleichtert dem Benutzer das Einsetzen und Entnehmen des freien Endes des Saugschlauchs bzw. des am freien Ende des Saugschlauchs angeordneten Filterelements.The sleeve is conveniently cylindrical in shape, as this facilitates the insertion and removal of the free end of the suction hose or the filter element arranged at the free end of the suction hose.

Die Hülse ist vorteilhafterweise fluchtend zur Durchgangsöffnung des Schlauchfachabdeckelements ausgerichtet. Bei einer derartigen Ausgestaltung bildet die Hülse nicht nur ein Halteelement für das freie Ende des Saugschlauchs bzw. für das am freien Ende des Saugschlauchs angeordnete Filterelement, sondern die Hülse bildet auch ein Führungselement, das das Herausziehen des Saugschlauchs aus dem Schlauchfach und das Einführen des Saugschlauchs in das Schlauchfach erleichtert.The sleeve is advantageously aligned in alignment with the passage opening of the Schlauchfachabdeckelements. In such an embodiment, the sleeve not only forms a holding element for the free end of the suction hose or for the arranged at the free end of the suction hose filter element, but the sleeve also forms a guide member, the withdrawal of the suction hose from the hose compartment and the insertion of the suction hose facilitated in the hose compartment.

Bei einer bevorzugten Ausgestaltung der Erfindung weist das Schlauchfachabdeckelement zwei taschenartige Vertiefungen auf, zwischen denen das Halteteil angeordnet ist und die sich jeweils an eine Ausnehmung des Halteteils anschließen. Die beiden Vertiefungen erleichtern es dem Benutzer, das freie Ende des Saugschlauchs bzw. das am freien Ende des Saugschlauchs angeordnete Filterelement zu ergreifen. Der Benutzer kann hierbei beispielsweise mit Daumen und Zeigefinger in die taschenartigen Vertiefungen eintauchen und dann das freie Ende des Saugschlauchs oder das am freien Ende des Saugschlauchs angeordnete Filterelement durch die Ausnehmungen des Halteteils hindurch ergreifen.In a preferred embodiment of the invention, the Schlauchfachabdeckelement two pocket-like depressions, between which the holding part is arranged and which in each case adjoin a recess of the holding part. The two recesses make it easier for the user to grasp the free end of the suction hose or the filter element arranged at the free end of the suction hose. The user can dive for example with thumb and forefinger in the pocket-like depressions and then the free end of the suction hose or at the free end of the Suction hose arranged filter element through the recesses of the holding part through.

Das Gehäuse des erfindungsgemäßen Hochdruckreinigungsgeräts weist bevorzugt zwei Halbschalen auf, die zumindest einen Teil der Motorpumpeneinheit zwischen sich aufnehmen. Zusätzlich zu den beiden Halbschalen kann mindestens ein weiteres Gehäuseteil zum Einsatz kommen, sodass die Motorpumpeneinheit allseits vom Gehäuse umgeben ist.The housing of the high-pressure cleaning device according to the invention preferably has two half shells which receive at least a portion of the motor pump unit between them. In addition to the two half shells, at least one further housing part can be used so that the motor pump unit is surrounded on all sides by the housing.

Günstigerweise wird das Schlauchfach von zwei Halbschalen des Gehäuses definiert, an denen das Schlauchfachabdeckelement lösbar oder unlösbar gehalten ist. Die beiden Halbschalen können somit das Schlauchfachabdeckelement zwischen sich aufnehmen. Dies hat eine sehr einfache Montage des Schlauchfachabdeckelements am Gehäuse des Hochdruckreinigungsgeräts zur Folge.Conveniently, the hose compartment is defined by two half-shells of the housing, where the Schlauchfachabdeckelement is releasably or permanently held. The two half shells can thus accommodate the Schlauchfachabdeckelement between them. This results in a very simple installation of Schlauchfachabdeckelements on the housing of the high-pressure cleaner.

Die beiden Halbschalen definieren bei einer vorteilhaften Ausführungsform der Erfindung eine Montageöffnung, die das Schlauchfach freigibt und an der das Schlauchfachabdeckelement gehalten ist.In an advantageous embodiment of the invention, the two half shells define a mounting opening which releases the hose compartment and on which the hose compartment cover element is held.

Günstig ist es, wenn die beiden Halbschalen jeweils eine Hälfte des Schlauchfachs ausbilden. Besonders günstig ist es, wenn die beiden Halbschalen jeweils eine Hälfte der Montageöffnung definieren. Werden die beiden Halbschalen zusammengefügt, dann wird dadurch das Schlauchfach gebildet, ohne dass zusätzliche Bauelemente zum Einsatz kommen müssen. Es ist lediglich erforderlich, an der von den beiden Halbschalen definierten Montageöffnung das Schlauchfachabdeckelement zu positionieren.It is advantageous if the two half shells each form one half of the hose compartment. It is particularly favorable if the two half shells each define one half of the mounting opening. If the two half-shells are joined together, then the hose compartment is formed without the need for additional components. It is only necessary to position the Schlauchfachabdeckelement on the assembly opening defined by the two half-shells.

Das Schlauchfachabdeckelement hintergreift bei einer vorteilhaften Ausführungsform der Erfindung einen von den beiden Halbschalen gebildeten Rand der Montageöffnung.The Schlauchfachabdeckelement engages in an advantageous embodiment of the invention, an edge formed by the two half-shells of the mounting hole.

Besonders vorteilhaft ist es, wenn das Schlauchfachabdeckelement einen auf den Rand der Montageöffnung aufsetzbaren Stützrand sowie die Montageöffnung hintergreifende Befestigungsglieder aufweist. Die Befestigungsglieder des Schlauchfachabdeckelements stehen bei einer vorteilhaften Ausführungsform der Erfindung von einer dem Innenraum des Schlauchfachs zugewandten Rückseite einer die Montageöffnung abdeckenden Wandung des Schlauchfachabdeckelements ab.It is particularly advantageous if the hose compartment cover element has a support rim which can be placed on the edge of the mounting opening and fastening members engaging behind the mounting opening. The attachment members of the Schlauchfachabdeckelements are in an advantageous embodiment of the invention from a the interior of the hose compartment facing back of a mounting opening covering the wall of Schlauchfachabdeckelements from.

Vorteilhafterweise umfasst das Schlauchfachabdeckelement vier Befestigungsglieder, die den Rand der Montageöffnung hintergreifen, wobei jeweils zwei Befestigungsglieder einander diametral gegenüberliegen.Advantageously, the Schlauchfachabdeckelement four fastening members which engage behind the edge of the mounting hole, wherein each two fastening members are diametrically opposed.

Die beiden Halbschalen des Gehäuses des erfindungsgemäßen Hochdruckreinigungsgeräts bilden vorteilhafterweise einen Tragegriff aus, wobei an einem ersten Ende des Tragegriffs das vom Schlauchfachabdeckelement abgedeckte Schlauchfach angeordnet ist. Der Tragegriff erleichtert den Transport des Hochdruckreinigungsgeräts und die Positionierung des Schlauchfachs und des Schlauchfachabdeckelements an einem Ende des Tragegriffs erleichtert die Bedienung des Hochdruckreinigungsgeräts, da der Benutzer den Tragegriff und damit auch das an einem Ende des Tragegriffs angeordnete Schlauchfach auf einfache Weise erkennen kann.The two half-shells of the housing of the high-pressure cleaning device according to the invention advantageously form a carrying handle, wherein at a first end of the carrying handle, the tubular compartment covered by the Schlauchfachabdeckelement is arranged. The carrying handle facilitates the transport of the high-pressure cleaning device and the positioning of the hose compartment and Schlauchfachabdeckelements at one end of the handle facilitates the operation of the high-pressure cleaner, since the user can easily recognize the carrying handle and thus arranged at one end of the handle hose pocket.

Von Vorteil ist es, wenn an einem zweiten Ende des Tragegriffs ein Hauptschalter des Hochdruckreinigungsgeräts angeordnet ist. Mittels des Hauptschalters kann das Hochdruckreinigungsgerät ein- und ausgeschaltet werden. Die Positionierung des Schlauchfachs an einem ersten Ende des Tragegriffs und des Hauptschalters am anderen Ende des Tragegriffs hat eine weitere Vereinfachung der Handhabung des Hochdruckreinigungsgeräts zur Folge.It is advantageous if a main switch of the high-pressure cleaning device is arranged at a second end of the carrying handle. By means of the main switch, the high-pressure cleaning device can be switched on and off. The positioning of the hose compartment at a first end of the carrying handle and the main switch at the other end of the carrying handle further simplifies the handling of the high-pressure cleaning appliance.

Von Vorteil ist es, wenn die beiden Halbschalen des Gehäuses in einer Gebrauchslage des Hochdruckreinigungsgeräts eine vertikal ausgerichtete Trennebene definieren und das Schlauchfachabdeckelement spiegelsymmetrisch zur Trennebene ausgestaltet ist. Unter einer Gebrauchslage des Hochdruckreinigungsgeräts wird hierbei eine Lage des Hochdruckreinigungsgeräts verstanden, die es während des Betriebs des Hochdruckreinigungsgeräts einnehmen kann. Die Bereitstellung einer vertikalen Trennebene ermöglicht eine besonders einfache Montage des Hochdruckreinigungsgeräts, da die beiden Halbschalen seitlich an die Motorpumpeneinheit angesetzt werden können, um diese nach erfolgter Montage in Umfangsrichtung zumindest teilweise zu umgeben. Die beiden Halbschalen können das Schlauchfach definieren und zwischen sich das Schlauchfachabdeckelement aufnehmen. Eine spiegelsymmetrische Ausgestaltung des Schlauchfachabdeckelements relativ zu der von den beiden Halbschalen gebildeten Trennebene hat sich als günstig erwiesen. Die Herstellung des Schlauchfachabdeckelements wird dadurch vereinfacht und das Schlauchfachabdeckelement kann auf besonders einfache Weise zwischen den beiden Halbschalen positioniert werden und ist nach erfolgter Montage für den Benutzer deutlich erkennbar.It is advantageous if the two half-shells of the housing in a position of use of the high-pressure cleaning device define a vertically oriented parting plane and the Schlauchfachabdeckelement is designed mirror-symmetrically to the parting plane. Under a position of use of High-pressure cleaning device is understood here a position of the high-pressure cleaner, which can take it during operation of the high-pressure cleaner. The provision of a vertical parting plane allows a particularly simple installation of the high-pressure cleaning device, since the two half shells can be attached laterally to the motor pump unit in order to at least partially surround them after assembly in the circumferential direction. The two half-shells can define the hose compartment and accommodate the Schlauchfachabdeckelement between them. A mirror-symmetrical configuration of the Schlauchfachabdeckelements relative to the parting plane formed by the two half-shells has proved to be favorable. The production of Schlauchfachabdeckelements is simplified and the Schlauchfachabdeckelement can be positioned in a particularly simple manner between the two half-shells and is clearly visible after the installation for the user.

Vorteilhafterweise sind die beiden Halbschalen und das Schlauchfachabdeckelement als Kunststoffformteile ausgestaltet. Dies ermöglicht eine besonders kostengünstige Herstellung der beiden Halbschalen und des Schlauchfachabdeckelements.Advantageously, the two half-shells and Schlauchfachabdeckelement are designed as plastic moldings. This allows a particularly cost-effective production of the two half-shells and Schlauchfachabdeckelements.

Wie eingangs erwähnt, kann am freien Ende des Saugschlauchs ein Filterelement angeordnet sein zum Filtrieren des von der Pumpe angesaugten Reinigungsmittels. Von besonderem Vorteil ist es, wenn in das Filterelement ein in Richtung der Pumpe öffnendes Rückschlagventil integriert ist. Das Rückschlagventil stellt sicher, dass der Saugschlauch nur in einer Richtung von Flüssigkeit durchströmt werden kann. Ein unbeabsichtigtes Entweichen von Flüssigkeit über den Saugschlauch aus dem Hochdruckreinigungsgerät wird dadurch vermieden.As mentioned above, a filter element may be arranged at the free end of the suction hose for filtering the detergent sucked by the pump. It is particularly advantageous if in the filter element an opening in the direction of the pump check valve is integrated. The check valve ensures that the suction hose can only be flowed through in one direction by liquid. An inadvertent escape of liquid through the suction hose from the high-pressure cleaner is thereby avoided.

In der Zeichnung ist schematisch ein erfindungsgemäßes Hochdruckreinigungsgerät 10 in einer Gebrauchslage dargestellt, in der eine Längsachse 12 des Hochdruckreinigungsgeräts 10 vertikal ausgerichtet ist. Das Hochdruckreinigungsgerät 10 umfasst ein Gehäuse 14 mit einem oberen Gehäusebereich 16 und einem unteren Gehäusebereich 18, die gemeinsam eine Motorpumpeneinheit 20 mit einem Motor 22 und einer vom Motor 22 angetriebenen Pumpe 24 umgeben. Mittels der Pumpe 24 kann eine Reinigungsflüssigkeit, vorzugsweise Wasser, unter Druck gesetzt werden. Die Reinigungsflüssigkeit kann der Pumpe 24 über ein erstes Anschlusselement 26 zugeführt werden, und die von der Pumpe 24 unter Druck gesetzte Reinigungsflüssigkeit kann von der Pumpe 24 über ein zweites Anschlusselement 28 abgegeben werden. An das erste Anschlusselement 26 kann eine Flüssigkeitszufuhrleitung angeschlossen werden, und an das zweite Anschlusselement 28 kann eine Flüssigkeitsabgabeleitung angeschlossen werden, beispielsweise ein Druckschlauch.The drawing shows schematically an inventive high-pressure cleaning device 10 is shown in a position of use, in which a longitudinal axis 12 of the high-pressure cleaning device 10 is vertically aligned. The high-pressure cleaning device 10 comprises a housing 14 having an upper housing area 16 and a lower housing area 18, which together surround a motor pump unit 20 with a motor 22 and a pump 24 driven by the motor 22. By means of the pump 24, a cleaning liquid, preferably water, can be pressurized. The cleaning fluid can the Pump 24 can be supplied via a first connecting element 26, and the cleaning fluid pressurized by the pump 24 can be discharged from the pump 24 via a second connecting element 28. A liquid supply line can be connected to the first connection element 26, and a liquid discharge line, for example a pressure hose, can be connected to the second connection element 28.

Am unteren Gehäusebereich 18 sind zwei Laufräder 30, 32 drehbar gelagert. Mittels der Laufräder 30, 32 kann das Hochdruckreinigungsgerät 10 entlang einer Bodenfläche verfahren werden. Hierzu kann das Hochdruckreinigungsgerät 10 ausgehend von seiner in Figur 1 dargestellten Gebrauchslage, in der die Längsachse 12 vertikal ausgerichtet ist, um eine gemeinsame Drehachse 34 der beiden Laufräder 30, 32 verschwenkt werden, so dass das Hochdruckreinigungsgerät 10 anschließend nach Art einer Sackkarre verfahren werden kann.At the lower housing portion 18, two wheels 30, 32 are rotatably mounted. By means of the wheels 30, 32, the high-pressure cleaning device 10 can be moved along a bottom surface. For this purpose, the high-pressure cleaning device 10, starting from its in FIG. 1 shown use position in which the longitudinal axis 12 is vertically aligned to a common axis of rotation 34 of the two wheels 30, 32 are pivoted, so that the high-pressure cleaning device 10 can then be moved in the manner of a sack truck.

Das Hochdruckreinigungsgerät 10 weist einen U-förmigen Schubbügel 36 auf, der das Verfahren des Hochdruckreinigungsgeräts 10 erleichtert.The high-pressure cleaner 10 has a U-shaped push bar 36, which facilitates the process of the high-pressure cleaner 10.

Der obere Gehäusebereich 16 umfasste eine erste Halbschale 38 und eine zweite Halbschale 40. Die beiden Halbschalen 38, 40 umgeben einen dem Schubbügel 36 zugewandten oberen Bereich der Motorpumpeneinheit 20 in Umfangsrichtung und sind im Wesentlichen spiegelsymmetrisch zueinander ausgerichtet. Sie bilden zwischen sich eine im Wesentlichen vertikal ausgerichtete Trennebene 42, in der sie mit ihren einander zugewandten Rändern aufeinandertreffen und zwischen sich eine Trennfuge ausbilden.The upper housing area 16 comprises a first half-shell 38 and a second half-shell 40. The two half-shells 38, 40 surround an upper area of the motor pump unit 20 facing the push bar 36 in the circumferential direction and are oriented essentially mirror-symmetrically with respect to one another. They form between them a substantially vertically oriented parting plane 42, in which they meet with their edges facing each other and form a parting line between them.

An ihren einander abgewandten Außenseiten tragen die beiden Halbschalen 38, 40 jeweils ein Abdeckteil 44 bzw. 46, das einen von den Halbschalen 38, 40 außenseitig ausgebildeten Führungskanal für den Schubbügel 36 abdeckt. Das Abdeckteil 46 trägt ein Klemmteil 48, in das eine an sich bekannte und deshalb zur Erzielung einer besseren Übersicht in der Zeichnung nicht dargestellte Sprühlanze eingeklemmt werden kann. Die Sprühlanze kann an das freie Ende des Druckschlauchs angeschlossen werden, der über das zweite Anschlusselement 28 mit der Pumpe 24 verbunden werden kann.On their outer sides facing away from each other, the two half shells 38, 40 each carry a cover part 44 or 46 which covers a guide channel for the push bar 36 formed on the outside by the half shells 38, 40. The cover 46 carries a clamping member 48, in which a known per se and therefore to achieve a better overview in the drawing, not shown spray lance can be clamped. The spray lance can be connected to the free end of the pressure hose to be connected, which can be connected via the second connection element 28 to the pump 24.

Die beiden Halbschalen 38, 40 bilden einen Tragegriff 50 aus und an einem unteren Ende des Tragegriffs 50 definieren die beiden Halbschalen 38, 40 gemeinsam ein Schlauchfach 52, das von einem Schlauchfachabdeckelement 54 abgedeckt ist und das einen Aufnahmeraum für einen Saugschlauch 56 ausbildet. Dies wird insbesondere aus Figur 7 deutlich. Ein erster Endbereich 58 des Saugschlauchs 56 ist durch eine Auslassöffnung 60 des Schlauchfachs 52 hindurchgeführt und steht mit der Pumpe 24 in Strömungsverbindung. Hierzu kann das über die Auslassöffnung 60 aus dem Schlauchfach 52 herausgeführte, in der Zeichnung nicht dargestellte erste Ende des Saugschlauchs 56 unmittelbar an die Pumpe 24 angeschlossen sein. Alternativ kann vorgesehen sein, dass das erste Ende des Saugschlauchs 56 an ein in der Zeichnung nicht dargestelltes, dem Fachmann an sich bekanntes Verbindungsglied des ersten Anschlusselements 26 angeschlossen ist, über das das Anschlusselement 26 mit der Pumpe 24 in Strömungsverbindung steht. Über den Saugschlauch 56 kann der Pumpe 24 bei Bedarf ein flüssiges Reinigungsmittel zugeführt werden, das der von der Pumpe geförderten Reinigungsflüssigkeit beigemischt werden kann.The two half shells 38, 40 form a carrying handle 50 and at a lower end of the carrying handle 50, the two half shells 38, 40 together define a hose compartment 52 which is covered by a Schlauchfachabdeckelement 54 and which forms a receiving space for a suction hose 56. This is especially true FIG. 7 clear. A first end portion 58 of the suction hose 56 is passed through an outlet opening 60 of the hose compartment 52 and is in fluid communication with the pump 24. For this purpose, the first end of the suction hose 56, which is led out of the hose compartment 52 via the outlet opening 60 and not shown in the drawing, can be connected directly to the pump 24. Alternatively it can be provided that the first end of the suction hose 56 is connected to a not shown in the drawing, the skilled worker per se known connection member of the first connection element 26, via which the connection element 26 is in flow communication with the pump 24. If necessary, a liquid cleaning agent can be supplied to the pump 24 via the suction hose 56, which can be admixed with the cleaning liquid conveyed by the pump.

Das der Pumpe 24 abgewandte freie Ende 62 des Saugschlauchs 56 ist an ein Filterelement 64 angeschlossen, in das ein in der Zeichnung nur schematisch dargestelltes Rückschlagventil 66 integriert ist. Mittels des Filterelements 64 kann das der Pumpe 24 bei Bedarf zugeführte Reinigungsmittel gefiltert werden, und das Rückschlagventil 66, das in Richtung der Pumpe 24 öffnet, stellt sicher, dass Flüssigkeit nicht unbeabsichtigt von der Pumpe 24 über den Saugschlauch 56 aus dem Hochdruckreinigungsgerät 10 herausfließen kann.The pump 24 remote from the free end 62 of the suction hose 56 is connected to a filter element 64, in which a in the drawing only schematically illustrated check valve 66 is integrated. By means of the filter element 64, the cleaning agent supplied to the pump 24 can be filtered if necessary, and the check valve 66, which opens in the direction of the pump 24, ensures that fluid can not inadvertently flow out of the high-pressure cleaning device 10 from the pump 24 via the suction hose 56 ,

Das Schlauchfach 52 wird auf seiner der Motorpumpeneinheit 20 zugewandten Rückseite von einer Rückwand begrenzt, die von einem ersten Rückwandabschnitt 68 und einem zweiten Rückwandabschnitt 70 gebildet wird. Der erste Rückwandabschnitt 68 wird von der ersten Halbschale 38 gebildet und der zweite Rückwandabschnitt 70 wird von der zweiten Halbschale 40 gebildet. Der erste Rückwandabschnitt 68 weist die voranstehend bereits erwähnte Auslassöffnung 60 auf, über die der der Pumpe 24 zugewandte erste Endbereich 58 des Saugschlauchs 56 rückseitig aus dem Schlauchfach 52 herausgeführt werden kann.The hose compartment 52 is bounded on its rear side facing the motor pump unit 20 by a rear wall, which is formed by a first rear wall section 68 and a second rear wall section 70.

Die Montageöffnung 84 des Schlauchfachs 52 ist von einem Schlauchfachabdeckelement 54 abgedeckt, das zwischen den beiden Halbschalen 38, 40 angeordnet und spiegelsymmetrisch zu der von den beiden Halbschalen 38, 40 definierten Trennebene 42 ausgestaltet ist. Dies wird insbesondere aus Figur 5 deutlich.The mounting opening 84 of the hose compartment 52 is covered by a Schlauchfachabdeckelement 54, which is arranged between the two half-shells 38, 40 and mirror-symmetrical to the plane defined by the two half-shells 38, 40 dividing plane 42 is configured. This is especially true FIG. 5 clear.

Das Schlauchfachabdeckelement 54 weist eine mittig angeordnete Hülse 90 auf, die ein Halteelement für das am freien Ende 62 des Saugschlauchs 56 angeordnete Filterelement 64 ausbildet. Das Filterelement 64 kann in die Hülse 90 vollständig eingeführt und mit der Hülse 90 verklemmt werden. Dies wird insbesondere aus Figur 7 deutlich.The Schlauchfachabdeckelement 54 has a centrally disposed sleeve 90, which forms a holding element for the arranged at the free end 62 of the suction hose 56 filter element 64. The filter element 64 can be fully inserted into the sleeve 90 and clamped to the sleeve 90. This is especially true FIG. 7 clear.

Die Hülse 90 ist fluchtend zu einer Durchgangsöffnung 92 des Schlauchfachabdeckelements 54 angeordnet, über die der Saugschlauch 56 bei Bedarf aus dem Schlauchfach 52 herausgezogen werden kann. Dies wird insbesondere aus Figur 8 deutlich.The sleeve 90 is arranged in alignment with a passage opening 92 of the Schlauchfachabdeckelements 54, via which the suction hose 56, if necessary the hose compartment 52 can be pulled out. This is especially true FIG. 8 clear.

Die Hülse 90 taucht in den Innenraum des Schlauchfachs 52 ein. Auf der der ersten Halbschale 38 zugewandten Seite weist die Hülse 90 eine erste Ausnehmung 94 auf und auf der der zweiten Halbschale 40 zugewandten Seite weist die Hülse 90 eine zweite Ausnehmung 96 auf. Die beiden Ausnehmungen 94, 96 liegen einander diametral gegenüber und erstrecken sich bis an das der Durchgangsöffnung 92 abgewandte vordere Ende 98 der Hülse 90.The sleeve 90 dips into the interior of the hose compartment 52. On the side facing the first half-shell 38, the sleeve 90 has a first recess 94 and on the side facing the second half-shell 40, the sleeve 90 has a second recess 96. The two recesses 94, 96 are diametrically opposed to each other and extend up to the passage opening 92 facing away from the front end 98 of the sleeve 90th

An die erste Ausnehmung 94 schließt sich auf der dem Schlauchfach 52 abgewandten Vorderseite 100 des Schlauchfachabdeckelements 54 eine erste wannen- oder taschenartige Vertiefung 102 an, und an die zweite Ausnehmung 96 schließt sich auf der Vorderseite 100 des Schlauchfachabdeckelements 54 eine zweite wannen- oder taschenartige Vertiefung 104 an. Die beiden Vertiefungen 102, 104 ermöglichen es einem Benutzer, das in der Hülse 90 positionierte Filterelement 84 mit Daumen und Zeigefinger zu ergreifen, so dass er anschließend das Filterelement 64 der Hülse 90 entnehmen und gleichzeitig den mit dem Filterelement 64 verbundenen Saugschlauch 56 aus dem Schlauchfach 52 herausziehen kann. Dies gibt dem Benutzer die Möglichkeit, das Filterelement 64 in einen mit Reinigungsmittel befüllten Reinigungsmittelbehälter einzutauchen, so dass anschließend Reinigungsmittel von der Pumpe 24 über den Saugschlauch 56 angesaugt und der von der Pumpe 24 geförderten Reinigungsflüssigkeit beigemischt werden kann. Als Reinigungsmittel kann beispielsweise eine Seifenlösung zum Einsatz kommen. Durch die Beimischung des Reinigungsmittels kann die vom Hochdruckreinigungsgerät 10 erzielbare Reinigungswirkung verbessert werden.The first recess 94 is followed by a first pocket or pocket-like depression 102 on the front side 100 of the tubular covering element 54 facing away from the tubular compartment 52, and the second recess 96 is followed by a second pocket or pocket-like depression on the front side 100 of the tubular covering element 54 104 on. The two recesses 102, 104 enable a user to grasp the filter element 84 positioned in the sleeve 90 with their thumb and forefinger so that they subsequently remove the filter element 64 of the sleeve 90 and simultaneously the suction hose 56 connected to the filter element 64 from the hose compartment 52 can pull out. This gives the user the opportunity to immerse the filter element 64 in a detergent container filled with detergent, so that subsequently detergent can be sucked by the pump 24 via the suction hose 56 and the pumped from the pump 24 cleaning liquid can be added. As a cleaning agent, for example, a soap solution can be used. By admixing the cleaning agent, the cleaning effect achievable by the high-pressure cleaning device 10 can be improved.

Falls die Beimischung eines Reinigungsmittels nicht erforderlich ist, kann der Benutzer den Saugschlauch über die Durchgangsöffnung 92 in das Schlauchfach 52 so weit einführen, bis das am freien Ende 62 des Saugschlauchs 56 angeordnete Filterelement 64 mit dem integrierten Rückschlagventil 66 vollständig von der Hülse 90 aufgenommen ist. Das Filterelement 64 kann hierbei zusammen mit dem Rückschlagventil 66 in die Hülse 90 eingeklemmt werden, so dass das Filterelement 64 zusammen mit dem Rückschlagventil 66 zuverlässig in der Hülse 90 fixiert ist.If the admixture of a cleaning agent is not required, the user can insert the suction hose via the passage opening 92 in the hose compartment 52 until the arranged at the free end 62 of the suction hose 56 filter element 64 is fully received by the integrated check valve 66 of the sleeve 90 , The filter element 64 can in this case be clamped together with the check valve 66 in the sleeve 90, so that the filter element 64 is fixed together with the check valve 66 reliably in the sleeve 90.

Zur Festlegung des Schlauchfachabdeckelements 54 an den beiden Halbschalen 38, 40 weist das Schlauchfachabdeckelement 54 einen umlaufenden Stützrand 106 auf, der bei der Montage des Hochdruckreinigungsgerätes 10 auf den die Montageöffnung 84 umgebenden Montagerand 86 aufgesetzt werden kann, wobei der Montagerand 86 rückseitig von Befestigungsgliedern 110, 112, 114 und 116 hintergriffen wird, die von einer Wandung 108 des Schlauchfachabdeckelements 54 nach außen flügelartig abstehen. Zusätzlich zu ihrer Funktion, den Montagerand 86 zu hintergreifen, bilden die Befestigungsglieder 110, 112, 114 und 116 Verstärkungsrippen aus, die die mechanische Belastbarkeit des Schlauchfachabdeckelements 54 verbessern.Laying down the Schlauchfachabdeckelements 54 on the two half-shells 38, 40, the Schlauchfachabdeckelement 54 has a circumferential support edge 106 which can be placed during assembly of the high-pressure cleaner 10 on the assembly opening 84 surrounding mounting edge 86, wherein the mounting edge 86 back of mounting members 110, 112, 114 and 116 which protrude from a wall 108 of the Schlauchfachabdeckelements 54 outwardly wing-like. In addition to their function of engaging the mounting edge 86, the attachment members 110, 112, 114 and 116 form reinforcing ribs which improve the mechanical strength of the tubular shroud member 54.

Das Hochdruckreinigungsgerät 10 kann mit und ohne Beimischung eines flüssigen Reinigungsmittels zu der von der Pumpe 24 geförderten Reinigungsflüssigkeit betrieben werden. Falls eine Beimischung von Reinigungsmittel nicht erforderlich ist, kann der Saugschlauch 56 im Schlauchfach 52 deponiert werden. Das Schlauchfach 52 wird vom Schlauchfachabdeckelement 54 abgedeckt, so dass der Saugschlauch 56 vor Beschädigungen geschützt ist. Das am freien Ende 62 des Saugschlauchs 56 angeordnete Filterelement 64 kann zusammen mit dem Rückschlagventil 66 in der Hülse 90 positioniert und darin festgeklemmt werden.The high-pressure cleaning device 10 can be operated with and without admixing a liquid cleaning agent to the funded by the pump 24 cleaning liquid. If an admixture of detergent is not required, the suction hose 56 can be deposited in the hose compartment 52. The hose compartment 52 is covered by Schlauchfachabdeckelement 54, so that the suction hose 56 is protected from damage. The filter element 64 arranged at the free end 62 of the suction hose 56 can be positioned together with the check valve 66 in the sleeve 90 and clamped therein.

Soll der Reinigungsflüssigkeit flüssiges Reinigungsmittel beigemischt werden, so kann der Benutzer das Filterelement 64 und das Rückschlagventil 66 über die taschenförmigen Vertiefungen 102, 104 und die Ausnehmungen 94, 96 mit Daumen und Zeigefinger ergreifen und anschließend den Saugschlauch 56 aus dem Schlauchfach 52 herausziehen. Das freie Ende 62 des Saugschlauchs 56 kann anschließend zusammen mit dem Filterelement 64 und dem Rückschlagventil 66 in einen mit Reinigungsmittel befüllten Reinigungsmittelbehälter eingetaucht werden, so dass anschließend Reinigungsmittel von der Pumpe 24 über den Saugschlauch 56 angesaugt werden kann und das Reinigungsmittel der von der Pumpe geforderten Reinigungsflüssigkeit beigemischt werden kann. Ist eine Beimischung nicht mehr erforderlich, so kann der Benutzer den Saugschlauch 56 durch die Durchgangsöffnung 52 hindurch wieder in das Schlauchfach 52 einführen und anschließend das Filterelement 64 zusammen mit dem Rückschlagventil 66 in der Hülse 90 positionieren.If liquid cleaning agent is added to the cleaning liquid, the user can grasp the filter element 64 and the check valve 66 via the pocket-shaped depressions 102, 104 and the recesses 94, 96 with thumb and forefinger and then pull the suction hose 56 out of the hose compartment 52. The free end 62 of the suction hose 56 can then be immersed together with the filter element 64 and the check valve 66 in a filled with detergent detergent container, so that subsequently cleaning agent from the pump 24th can be sucked in via the suction hose 56 and the detergent can be added to the required cleaning liquid from the pump. If admixture is no longer necessary, the user can insert the suction hose 56 through the passage opening 52 back into the hose compartment 52 and then position the filter element 64 together with the check valve 66 in the sleeve 90.
