Description

Die Erfindung betrifft ein Hochdruckreinigungsgerät mit einer in einem Gehäuse angeordneten Hochdruckpumpe, einer Flüssigkeitszufuhr, einer Druckleitung für die von der Hochdruckpumpe geförderte Flüssigkeit und mit einer Chemikalienansaugung, die über eine Ansaugleitung eine Chemikalie aus einem Vorratsbehälter ansaugt, der im Gehäuse angeordnet ist, siehe z.B. DE-A-37 24 386.The invention relates to a high-pressure cleaning device with a high-pressure pump arranged in a housing, a liquid supply, a pressure line for the liquid conveyed by the high-pressure pump and with a chemical suction device which sucks in a chemical via a suction line from a storage container which is arranged in the housing, see e.g. DE-A-37 24 386.

Bei Hochdruckreinigungsgeräten mit Chemikalienansaugung ist es bekannt, einen Vorratsbehälter, beispielsweise eine mit Chemikalie gefüllte Flasche, neben das Gerät zu stellen und einen Ansaugschlauch in die Flasche einzuführen. Es ergeben sich natürlich dann Probleme, wenn das Hochdruckreinigungsgerät an einem anderen Ort betrieben werden soll, da dann neben dem Gerät auch die Vorratsflasche transportiert werden muß.In the case of high-pressure cleaning devices with chemical suction, it is known to place a storage container, for example a bottle filled with chemicals, next to the device and to insert a suction hose into the bottle. Problems naturally arise when the high-pressure cleaning device is to be operated at a different location, since the storage bottle must then also be transported in addition to the device.

Es sind auch Hochdruckreinigungsgeräte bekannt, bei denen im Gerät selbst ein Chemikalienbehälter vorgesehen ist, der über eine Einfüllöffnung beispielsweise mittels eines Trichters befüllt werden kann. Dies ist ein umständlicher Vorgang, bei dem häufig Chemikalie verschüttet wird.High-pressure cleaning devices are also known, in which a chemical container is provided in the device itself, which can be filled via a filling opening, for example by means of a funnel. This is a cumbersome process where chemical is often spilled.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Hochdruckreinigungsgerät so auszubilden, daß einerseits beim Transport des Gerätes kein zusätzlicher Transport eines getrennten Chemikalienvorratsbehälters notwendig ist und daß andererseits das Befüllen des Hochdruckreinigungsgerätes mit Chemikalie in einfachster Weise vorgenommen werden kann.It is an object of the invention to design a generic high-pressure cleaning device so that on the one hand Transport of the device no additional transport of a separate chemical storage container is necessary and that, on the other hand, the filling of the high-pressure cleaning device with chemical can be carried out in the simplest way.

Diese Aufgabe wird bei einem Hochdruckreinigungsgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß im Gehäuse ein mittels einer Abdeckung verschließbares Fach angeordnet ist, in dem sich ein herausnehmbarer Chemikalienbehälter befindet, daß der Chemikalienbehälter eine mit einem abnehmbaren Deckel verschließbare Öffnung aufweist, daß die Ansaugleitung den Deckel durchsetzt und in das Behälterinnere eintaucht und daß der Behälter an der Abdeckung lösbar gehalten ist.This object is achieved in a high-pressure cleaning device of the type described at the outset in that a compartment which can be closed by means of a cover is arranged in the housing, in which there is a removable chemical container, the chemical container has an opening which can be closed with a removable cover, and the suction line provides the opening Cover penetrates and dips into the interior of the container and that the container is releasably held on the cover.

Bei dem erfindungsgemäßen Hochdruckreinigungsgerät ist somit ein völlig selbständiger und mittels des Deckels dicht verschließbarer Chemikalienbehälter in einem speziellen Fach angeordnet. Zum Nachfüllen einer Chemikalie wird dieses Fach geöffnet, der leere Chemikalienbehälter kann dann nach Abnahme des Deckels aus dem Fach herausgenommen und entweder außerhalb des Gerätes nachgefüllt oder durch einen bereits vorher gefüllten Chemikalienbehälter ersetzt werden. Das Nachfüllen ist dabei wesentlich einfacher als beim Nachfüllen eines fest eingebauten Behälters mittels eines Trichters, es können beispielsweise von einem Chemikalienhersteller gelieferte Vorratsflaschen etc. unmittelbar verwendet werden. Trotzdem ist sichergestellt, daß der Chemikalienbehälter im Inneren des Gerätes durch den Deckel dicht verschlossen ist, so daß das Hochdruckreinigungsgerät auch beim Verschwenken oder in liegender Arbeitsweise ohne weiteres betrieben werden kann.In the high-pressure cleaning device according to the invention, a completely independent chemical container which can be tightly closed by means of the lid is thus arranged in a special compartment. To refill a chemical, this compartment is opened, the empty chemical container can then be removed from the compartment after removing the lid and either refilled outside the device or replaced by a previously filled chemical container. Refilling is much easier than refilling a built-in container using a funnel, for example, storage bottles etc. supplied by a chemical manufacturer can be used directly. Nevertheless, it is ensured that the chemical container inside the device is tightly closed by the lid, so that the high-pressure cleaning device can be operated without difficulty even when swiveling or lying down.

Dabei ist besonders vorteilhaft, daß der Behälter an der Abdeckung lösbar gehalten ist, denn allein durch Öffnen bzw. Abnahme der Abdeckung ist es auf diese Weise möglich, den Chemikalienbehälter aus dem Hochdruckreinigungsgerät zu entnehmen und so zugänglich zu machen, daß er nach Lösung von der Abdeckung in einfacher Weise zum Nachfüllen entnommen werden kann. Der Chemikalienbehälter kann an der Abdeckung beispielsweise durch eine Rastverbindung oder durch eine Spanneinrichtung, beispielsweise ein Spannband, gehalten sein.It is particularly advantageous that the container is releasably held on the cover, because only by opening or removing the cover it is possible in this way to remove the chemical container from the high-pressure cleaning device and to make it accessible so that it can be removed from the Cover can be easily removed for refilling. The chemical container can be held on the cover, for example by a snap connection or by a tensioning device, for example a tensioning strap.

Bei einer bevorzugten Ausführungsform ist im Deckel ein Luftzufuhrventil angeordnet, welches bei der Entnahme der Chemikalie aus dem Vorratsbehälter für einen Druckausgleich im Behälterinneren sorgt.In a preferred embodiment, an air supply valve is arranged in the lid, which ensures a pressure equalization in the interior of the container when the chemical is removed from the storage container.

Dabei kann es vorteilhaft sein, wenn eine Öffnung im Deckel, durch welche die Ansaugleitung hindurchtritt, mit ventilartigen Dichtlippen versehen ist, die einen Eintritt von Luft aus der Umgebung in den Behälter ermöglichen, das Behälterinnere jedoch gegen einen Austritt der Flüssigkeit nach außen abdichten. Bei einer solchen Ausgestaltung übernimmt also die Dichtung in der Deckelöffnung, durch die die Ansaugleitung hindurchtritt, gleichzeitig auch die Funktion einen Ventils, das nur in Richtung auf das Behälterinnere zu öffnen ist, jedoch nicht in umgekehrter Richtung.It can be advantageous if an opening in the cover, through which the suction line passes, is provided with valve-like sealing lips which allow air to enter the container from the environment, but seal the container interior against the liquid from escaping to the outside. In such an embodiment, the seal in the lid opening through which the suction line passes also simultaneously takes over the function of a valve that can only be opened in the direction of the interior of the container, but not in the opposite direction.

Günstig ist es, wenn der Behälter zumindest bereichsweise durchsichtig ist und in diesem Bereich der Abdeckung ein Fenster angeordnet ist. Auf diese Weise ist von der Außenseite des Gehäuses her eine Füllhöhenüberprüfung möglich.It is favorable if the container is transparent at least in some areas and a window is arranged in this area of the cover. In this way, a filling level check is possible from the outside of the housing.

Insbesondere kann das Fenster eine schlitzförmige Durchbrechung in der Abdeckung sein, in die der Behälter mit einem Vorsprung eintaucht. Dies führt einerseits dazu, daß die Füllhöhe besonders gut von der Außenseite des Gehäuses her abgelesen werden kann, andererseits läßt sich dadurch ein Formschluß und eine Führung des Behälters an der Abdeckung erreichen, die dazu beiträgt, den Behälter an der Abdeckung lösbar, jedoch im eingesetzten Zustand unbeweglich festzulegen.In particular, the window can be a slot-shaped opening in the cover, into which the container dips with a projection. This leads on the one hand to the fact that the fill level can be read particularly well from the outside of the housing, on the other hand it can achieve a positive fit and a guidance of the container on the cover, which contributes to the container on the cover being detachable but in use State immobile.

Günstig ist es, wenn der Behälter als Blasformteil ausgebildet ist.It is advantageous if the container is designed as a blow molded part.

Die nachfolgende Beschreibung einer bevorzugten Ausführungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:

Figur 2 :
eine Ansicht des Chemikalienfaches in Richtung des Pfeiles A in Figur 1.
The following description of a preferred embodiment of the invention serves in conjunction with the drawing for a more detailed explanation. Show it:
Figure 1:
a side view of a high pressure cleaning device, which is shown broken in the area of a chemical compartment, and
Figure 2:
a view of the chemical compartment in the direction of arrow A in Figure 1.

In der Zeichnung ist ein trag- und fahrbares Hochdruckreinigungsgerät 1 dargestellt. Dieses umfaßt in einem Gehäuse 2 eine in der Zeichnung nicht dargestellte Hochdruckpumpe mit einer Flüssigkeitszufuhr und einer die geförderte Flüssigkeit abgebenden Hochdruckleitung, die die geförderte Flüssigkeit beispielsweise einer Hochdrucksprühlanze oder dergleichen zuführt.In the drawing, a portable and mobile high-pressure cleaning device 1 is shown. This comprises in a housing 2 a high-pressure pump, not shown in the drawing, with a liquid supply and a high-pressure line delivering the conveyed liquid, which feeds the conveyed liquid, for example to a high-pressure spray lance or the like.

Im Inneren des Gehäuses 2 befindet sich an einer Seite ein Fach 3, welches mittels einer Abdeckung 4 abgeschlossen ist. Die Abdeckung 4 ist abnehmbar ausgebildet, beispielsweise kann sie nach Art einer Tür mit einem Scharnier angelenkt sein, oder die Abdeckung 4 ist als Facheinschub ausgebildet und wird in der eingeschobenen Stellung durch Magnete oder andere Halteelemente lösbar gehalten.On the inside of the housing 2 there is a compartment 3 on one side, which is closed off by a cover 4. The cover 4 is designed to be removable, for example it can be hinged like a door, or the cover 4 is designed as a slide-in module and is releasably held in the inserted position by magnets or other holding elements.

Die Abdeckung 4 weist an der Unterseite eine senkrecht in das Fach 3 hineinragende Stellfläche 5 auf, auf der ein Behälter 6 ruht. Dieser Behälter 6 füllt im wesentlichen den gesamten unteren Teil des Faches 3 aus. Er ist als Blasformbehälter aus Kunststoff hergestellt, vorzugsweise aus durchsichtigem Kunststoff, und bis auf eine Öffnung 7 an der Oberseite vollständig verschlossen. Die Öffnung 7 an der Oberseite befindet sich am Ende eines Einfüllstutzens 8, auf die Öffnung 7 ist ein Deckel 9 aufgesetzt.The cover 4 has on the underside a shelf 5 projecting vertically into the compartment 3, on which a container 6 rests. This container 6 essentially fills the entire lower part of the compartment 3. It is made as a blow molding container from plastic, preferably from transparent plastic, and is completely closed except for an opening 7 on the top. The opening 7 at the top is at the end of a filler neck 8, a lid 9 is placed on the opening 7.

Der Behälter 6 ist an der Abdeckung 4 lösbar gehalten, beispielsweise mittels einer in der Zeichnung nicht dargestellten elastischen Rastverbindung oder mittels eines Spannbandes.The container 6 is detachably held on the cover 4, for example by means of an elastic latching connection, not shown in the drawing, or by means of a tensioning strap.

In der Abdeckung 4 ist eine senkrechte, schlitzförmige Durchbrechung 10 angeordnet, die ein Fenster bildet, durch welches man den Behälter 6 sehen kann. Zumindest in diesem Bereich ist der Behälter durchsichtig ausgebildet, man erhält auf diese Weise eine Möglichkeit, in das Innere des Behälters zu blicken und den jeweiligen Füllstand im Behälter zu überwachen.A vertical, slot-shaped opening 10 is arranged in the cover 4, which forms a window through which the container 6 can be seen. At least in this area, the container is made transparent, in this way it is possible to look into the interior of the container and to monitor the respective fill level in the container.

Der Behälter ist im Bereich der Durchbrechung 10 sickenförmig vorgewölbt und greift mit dieser Vorwölbung 11 in die Durchbrechung 10 ein. Dadurch wird einerseits der Behälter im Fach gegen eine seitliche Verschiebung festgelegt, andererseits wird dadurch die Füllhöhenüberwachung erleichtert.The container is bulged in the area of the opening 10 and engages with this bulge 11 in the opening 10. On the one hand, this means that the container is fixed in the compartment against lateral displacement, and on the other hand, filling level monitoring is made easier.

Der den Behälter 6 verschließende, abnehmbare Deckel 9 weist eine Öffnung 12 auf, durch die ein Ansaugschlauch 13 hindurchgeführt ist, der an seinem freien Ende ein Sieb oder Filter 14 trägt. Der Ansaugschlauch 13 ist dabei so tief in den Behälter 6 eingetaucht, daß eine Ansaugung der im Behälter eingefüllten Chemikalie bis in den Bodenbereich möglich ist. Der Ansaugschlauch 13 führt in aus der Zeichnung nicht ersichtlicher Weise zu einem Injektor, in dem ein Unterdruck erzeugt wird. Die über den Ansaugschlauch 13 angesaugte Chemikalie wird der von der Hochdruckpumpe geförderten Flüssigkeit zugefügt, so daß das Hochdruckreinigungsgerät bei Chemikalienansaugung eine mit Chemikalie versetzte Reinigungsflüssigkeit abgibt.The removable cover 9, which closes the container 6, has an opening 12 through which a suction hose 13 is guided, which carries a sieve or filter 14 at its free end. The suction hose 13 is so deeply immersed in the container 6 that the chemical filled in the container can be sucked into the bottom area. The suction hose 13 leads to an injector, in which a negative pressure is generated, in a manner not shown in the drawing. The chemical sucked in via the suction hose 13 is added to the liquid conveyed by the high-pressure pump, so that the high-pressure cleaning device releases a cleaning liquid mixed with chemical when the chemical is sucked in.

Der Ansaugschlauch 13 ist üblicherweise gegenüber dem Deckel 9 abgedichtet, in diesem Falle befindet sich im Deckel 9 ein Lufteinlaßventil 15, durch welches Luft aus der Umgebung in das Behälterinnere eintreten kann, sobald der Druck im Inneren geringer ist als in der Umgebung. Dagegen verhindert dieses Ventil den Austritt von Flüssigkeit aus dem Behälterinneren.The suction hose 13 is usually sealed off from the lid 9, in this case there is an air inlet valve 15 in the lid 9, through which air from the environment can enter the interior of the container as soon as the pressure inside is lower than in the environment. In contrast, this valve prevents liquid from escaping from the inside of the container.

Alternativ oder zusätzlich zu dem Lufteinlaßventil 15 kann die Öffnung 12 gegenüber dem Ansaugschlauch 13 mittels einer Dichtlippe 16 abgedichtet sein, die elastisch nach innen umbiegbar ist, so daß auch über diese Abdichtung Luft in das Behälterinnere eintreten kann. Nach außen hin läßt sich diese Dichtlippe 16 jedoch nicht verbiegen, so daß Flüssigkeit aus dem Behälterinneren über diese als Ventil wirkende Dichtlippe nicht nach außen gelangen kann.As an alternative or in addition to the air inlet valve 15, the opening 12 can be sealed off from the suction hose 13 by means of a sealing lip 16 which can be bent elastically inwards, so that air can also enter the interior of the container via this seal. However, this sealing lip 16 cannot be bent outwards, so that liquid from the interior of the container cannot get out through this sealing lip, which acts as a valve.

Auf diese Weise ist sichergestellt, daß auch bei liegender Betriebsweise keine Chemikalie aus dem Behälter austreten kann, es sei denn über den Ansaugschlauch 13.In this way it is ensured that no chemical can escape from the container even when the operating mode is lying down, unless via the suction hose 13.

Zum Nachfüllen des Behälters 6 genügt es, die Abdeckung 4 vom Fach 3 abzunehmen, dabei nimmt man gleichzeitig den an der Abdeckung 4 gehaltenen Behälter mit aus dem Fach 3 heraus. Der Deckel 9 wird geöffnet, beispielsweise durch Abschrauben, und vom Behälter abgenommen; dabei wird auch der Ansaugschlauch 13 mit dem Sieb 14 aus dem Behälter herausgenommen.To refill the container 6, it is sufficient to remove the cover 4 from the compartment 3, at the same time taking the container held on the cover 4 out of the compartment 3. The lid 9 is opened, for example by unscrewing, and removed from the container; the suction hose 13 with the sieve 14 is also removed from the container.

Der Behälter 6 kann nunmehr an beliebiger Stelle nachgefüllt werden. Es ist auch möglich, den Behälter auszutauschen. Dazu wird er von der Abdeckung gelöst und durch einen gefüllten Behälter ersetzt.The container 6 can now be refilled at any point. It is also possible to replace the container. To do this, it is removed from the cover and replaced with a filled container.

Danach wird das Gerät wieder in umgekehrter Weise zusammengesetzt, das heißt der Ansaugschlauch 13 und das Sieb 14 werden in den Behälter eingeführt, der Deckel 9 wird dichtend aufgesetzt und der Behälter und die Abdeckung 4 werden in das Fach 3 eingeschoben.The device is then put together again in the reverse manner, that is to say the suction hose 13 and the sieve 14 are introduced into the container, the lid 9 is placed in a sealing manner and the container and the cover 4 are pushed into the compartment 3.

Bei dem beschriebenen Gerät ist der Behälter 6 als von der Abdeckung 4 getrenntes Teil ausgebildet. Bei einem abgewandelten, in der Zeichnung nicht dargestellten Ausführungsbeispiel könnte auch vorgesehen sein, daß der Behälter selbst die Abdeckung des Faches darstellt. Dazu wird der Behälter entsprechend geformt, so daß die Außenwand des Behälters gleichzeitig eine Gehäusewand bildet und auf diese Weise das Fach verschließt. Es wäre auch möglich, daß zwar eine entsprechende Abdeckung für das Fach vorgesehen ist, daß aber der Behälter mit dieser Abdeckung nicht lösbar verbunden ist, beispielsweise durch einstückige Ausformung oder durch Verklebung.In the device described, the container 6 is designed as a part separate from the cover 4. In a modified embodiment, not shown in the drawing, it could also be provided that the container itself represents the cover of the compartment. For this purpose, the container is shaped accordingly, so that the outer wall of the container simultaneously forms a housing wall and in this way closes the compartment. It would also be possible that a corresponding cover is provided for the compartment, but that the container is not releasably connected to this cover, for example by being molded in one piece or by gluing.
