Description

Die Erfindung betrifft ein Reinigungsgerät zum Trockensaugen, Naßsaugen und/oder zum Sprühextrahieren mit den im Oberbegriff des Patentanspruches 1 angegebenen Merkmalen.The invention relates to a cleaning device for dry suction, wet suction and / or for spray extraction with the features specified in the preamble of claim 1.

Reinigungsgeräte dieser Art werden insbesondere im gewerblichen Reinigungsbereich bereits eingesetzt, jedoch handelt es sich dabei um komplizierte und große Geräte, die zur Verwendung im Haushaltsbereich ungeeignet sind. Insbesondere ist es bei den bekannten Geräten nicht ohne weiteres möglich, die Geräte in einfachster Weise zwischen den einzelnen Betriebsarten umzustellen.Cleaning devices of this type are already being used in particular in the commercial cleaning sector, but these are complicated and large devices which are unsuitable for use in the household sector. In particular, it is not readily possible in the known devices to switch the devices between the individual operating modes in the simplest manner.

Aus der US-A-4 463 474 ist ein Reinigungsgerät bekannt, bei dem ein relativ kompakter Aufbau dadurch erreicht wird, daß ein Schmutzauffanggerät auf einem Wagen angeordnet und über ein Rohr mit einer Vakuumturbine verbunden ist.A cleaning device is known from US-A-4 463 474, in which a relatively compact construction is achieved in that a dirt collecting device is arranged on a carriage and connected to a vacuum turbine via a pipe.

Bei einem weiteren bekannten Reinigungsgerät dieser Art, wie es in der US-A-4 216 563 beschrieben ist, werden auf ein Fahrgestell ein Schmutzauffangbehälter und ein Flüssigkeitsbehälter nebeneinander aufgesetzt. Eine Saugverbindung wird über Anschlüsse hergestellt, die durch das Aufstellen der Schmutzauffangbehälters angedichtet werden. Dabei ist die Saugpumpe für die Flüssigkeit in dem aufgesetzten Behälter selbst angeordnet und wird über eine Steckverbindung mit dem Hauptgerät verbunden.In another known cleaning device of this type, as described in US Pat. No. 4,216,563, a dirt collecting container and a liquid container are placed side by side on a chassis. A suction connection is made via connections that are sealed by installing the dirt collector. The suction pump for the liquid is arranged in the container itself and is connected to the main unit via a plug connection.

Es ist Aufgabe der Erfindung, ein Reinigungsgerät der gattungsgemäßen Art derart zu verbessern, daß es im Aufbau möglichst einfach ist und gleichzeitig in einfachster Weise den Übergang von einer Betriebsart in die andere ermöglicht. Diese Aufgabe wird bei einem Reinigungsgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Öffnungen und die daran anschließenden Leitungsstücke der Behälter an einem Einschub angeordnet sind, der von oben her in eine Ausnehmung in einer Seitenwand des Behälters einsetzbar ist. Dadurch können gleich aufgebaute Behälter sowohl als Schmutzauffangbehälter als auch als Reinigungflüssigkeitsbehälter eingesetzt werden. Diese ansonsten gleichen Behälter werden mit den Einschüben versehen, die die entsprechenden Anschlüsse tragen. Je nach Einsatz können die jeweils gleichen Behälter daher einfach durch Einsetzen dieser Einschübe umgerüstet werden.It is an object of the invention to improve a cleaning device of the generic type in such a way that its construction is as simple as possible and at the same time enables the transition from one operating mode to the other in the simplest way. This object is achieved according to the invention in a cleaning device of the type described at the outset in that the openings and the adjoining line sections of the containers are arranged on an insert which can be inserted from above into a recess in a side wall of the container. As a result, containers of the same design can be used both as dirt collecting containers and as cleaning liquid containers. These otherwise identical containers are provided with the slide-in units which carry the corresponding connections. Depending on the application, the same containers can therefore be easily converted by inserting these inserts.

Diese Einschübe können in einer Gleitführung in der Seitenwand des Behälters verschiebbar sein, die beispielsweise als Nut- und Federpassung ausgeführt ist.These inserts can be displaceable in a sliding guide in the side wall of the container, which is designed, for example, as a tongue and groove fit.

Vorteilhaft ist es, wenn der Einschub in seiner eingeschobenen Stellung durch den verschlossenen Deckel des Behälters festgelegt ist. Dadurch kommt indirekt dem verschwenkten Tragegriff, der den Deckel in seiner geschlossenen Lage fixiert, auch noch die Aufgabe zu, die Einschübe in der Seitenwand des jeweiligen Behälters festzulegen.It is advantageous if the insert is fixed in its inserted position by the closed lid of the container. As a result, the pivoted carrying handle, which fixes the lid in its closed position, also indirectly has the task of fixing the inserts in the side wall of the respective container.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß an den Behältern je ein verschwenkbarer Tragegriff gelagert ist, der in einer ersten Stellung als Tragegriff vom Behälter absteht und in einer zweiten Stellung flach auf den Behälter aufgeleft ist, und daß der Tragegriff ein Spannelement trägt, das in der zweiten Stellung einen Vorsprung am Gehäuse hintergreift und den Behälter dadurch gegen die Anschlüsse des Gehäuses spannt, während es in der ersten Stellung von dem Vorsprung entfernt ist. Dieser Tragegriff hat somit eine Doppelfunktion, da er einerseits zum Tragen des abgenommenen Behälters dient, andererseits gleichzeitig die Spannvorrichtung bildet, mit der der Behälter gegen das Gehäuse gespannt ist.In a preferred embodiment it is provided that a pivotable handle is mounted on the containers, which projects in a first position as a handle from the container and is open in a second position flat on the container, and that the handle carries a clamping element which in the second position engages behind a projection on the housing and thereby clamps the container against the connections of the housing, while in the first position it is removed from the projection. This handle therefore has a double function, since it serves on the one hand to carry the removed container and on the other hand simultaneously forms the tensioning device with which the container is clamped against the housing.

Es ist dabei vorteilhaft, wenn das Spannelement und der Vorsprung längs einer geneigten Kontaktfläche so zusammenwirken, daß die den Behälter gegen die Anschlüsse des Gehäuses spannende Kraft beim Verschwenken des Tragegriffes in die zweite Stellung zunehmend erhöht wird. Dadurch kann durch die Schwenkbewegung des Tragegriffes die Anpreßkraft des Behälters gegen das Gehäuse erhöht werden. Um die Spannung zu halten, wird der Tragegriff vorzugsweise so gelagert, daß er in seine zweite Stellung über einen Todpunkt verschwenkt wird, so daß ein selbsttätiges Zurückschwenken nicht möglich ist. Es ist aber auch möglich, für den Trägegriff in der zweiten Stellung eine Fixierung vorzusehen, beispielsweise kann der Tragegriff federnd in eine Raste einschnappen.It is advantageous if the tensioning element and the projection cooperate along an inclined contact surface in such a way that the force exciting the container against the connections of the housing is increasingly increased when the handle is pivoted into the second position. As a result, the pressing force of the container against the housing can be increased by the pivoting movement of the handle. In order to keep the tension, the handle is preferably mounted so that it is pivoted into its second position over a dead center, so that an automatic pivoting back is not possible. However, it is also possible to provide a fixation for the handle in the second position, for example the handle can snap resiliently into a catch.

Es ist weiterhin vorteilhaft, wenn der Tragegriff in der zweiten Stellung an einem Deckel des Behälters anliegt und diesen gegen die Oberseite des Behälters drückt, und wenn der Tragegriff den Deckel in der ersten Stellung freigibt. Dadurch kommt dem Tragegriff noch eine weitere Funktion zu, nämlich die der Fixierung des Deckels auf dem jeweiligen Behälter. Der Benutzer kann zum Abnehmen des Behälters den Tragegriff nach oben schwenken, dadurch löst sich zwangsläufig der Behälter von seiner Wirkverbindung mit den Leitungen in Gehäuse, der Deckel wird abnehmbar und der Tragegriff steht zum Tragen zur Verfügung. Umgekehrt genügt es zum Einsetzen des Behälters, auf diesen einen Deckel aufzulegen und anschließend den Tragegriff in die zweite Stellung umzuschwenken, dadurch wird der Deckel fixiert und die Wirkverbindung mit den Leitungen im Gehäuse werden hergestellt. Der Tragegriff stört darüber hinaus in der umgelegten, zweiten Stellung nicht, da er dabei flächig am Deckel anliegt, vorzugsweise in einer entsprechenden Ausnehmung des Deckels, die den umgelegten Tragegriff aufnimmt.It is furthermore advantageous if the handle in the second position rests against a lid of the container and presses it against the top of the container, and if the handle releases the lid in the first position. As a result, the handle has another function, namely that of fixing the lid to the respective container. The user can swivel the handle upwards to remove the container, which inevitably releases the container from its operative connection with the lines in the housing, the lid is removable and the handle is available for carrying. Conversely, to insert the container, it is sufficient to place a lid on it and then to pivot the handle into the second position, thereby fixing the lid and establishing the operative connection with the lines in the housing. In addition, the handle does not interfere in the folded, second position, since it lies flat against the lid, preferably in a corresponding recess in the lid, which receives the folded handle.

Es ist vorteilhaft, wenn die Behälter einen rechteckförmigen Querschnitt haben und nebeneinander angeordnet sind, wobei sie mit ihren beiden senkrecht zu den aneinanderliegenden Anlageflächen verlaufenden Seitenflächen am Gehäuse anliegen. Dadurch ergibt sich ein besonders kompakter Aufbau der Gesamtanlage, der man den Aufbau aus einem Gehäuse und zwei einzelnen Behältern im zusammengesetzten Zustand nicht mehr ansieht.It is advantageous if the containers have a rectangular cross section and are arranged next to one another, with their two side surfaces running perpendicular to the abutting contact surfaces resting against the housing. This results in a particularly compact structure of the overall system, which is the structure of a housing and no longer looks at two individual containers in the assembled state.

Die Behälter können sich nach unten verjüngen, wodurch die Entleerung erleichtert wird.The containers can taper downwards, which makes emptying easier.

Bei einer weiteren bevorzugten Ausführungsform ist vorgesehen, daß die Behälter auf einer mit dem Gehäuse verbundenen Abstellfläche stehen, die einen umlaufenden, nach oben über die Abstellfläche hervorstehenden Rand aufweist. Dadurch wirkt diese Abstellfläche als Tropfenfangfläche, die eventuell am Behälter herunterlaufende Tropfen auffängt und dadurch verhindert, daß diese auf den Boden gelangen.In a further preferred embodiment it is provided that the containers stand on a storage surface connected to the housing, which has a peripheral edge which projects upwards above the storage surface. As a result, this shelf acts as a drip catcher, which catches any drops running down the container and thereby prevents them from reaching the bottom.

The connection 9 is connected to the pressure side of the feed pump 6. On the suction side, this feed pump 6 is connected to a further opening 14 in the side wall 13.

Desgleichen führt die mit der Saugseite des Saugaggregates 5 verbundene Absaugleitung 15 zu einer weiteren Öffnung 16 in der Seitenwand 13. Die Abluft wird von dem Saugaggregat 5 durch seitliche Schlitze 17 im Gehäuse an die Umgebung abgegeben.Likewise, the suction line 15 connected to the suction side of the suction unit 5 leads to a further opening 16 in the side wall 13. The exhaust air is discharged from the suction unit 5 to the environment through lateral slots 17 in the housing.

Die Bedienungselemente für die Förderpumpe und das Saugaggregat sind an der Oberseite 18 des Gehäuses angeordnet; dort befindet sich weiterhin ein Verschiebe- und Tragegriff 19 für das ganze Gerät.The controls for the feed pump and the suction unit are arranged on the top 18 of the housing; there is also a pushing and carrying handle 19 for the entire device.

Auf den freien Teil der Bodenplatte 2 sind neben dem Gehäuse 3 zwei Behälter 20 und 21 nebeneinander aufsetzbar, die beide einen rechteckigen Querschnitt haben. Die aneinander liegenden Seitenwände 22 bzw. 23 der beiden Behälter sowie die diesen gegenüberliegenden Seitenwände 24 bzw. 25 sind parallel zueinander angeordnet, die senkrecht dazu stehenden Seitenwände 26 und 27 bzw 28 und 29 laufen oben oben nach unten schräg auf einander zu, so daß sich die Behälter nach unten hin verjüngen.In addition to the housing 3, two containers 20 and 21 can be placed next to one another on the free part of the base plate 2, both of which have a rectangular cross section. The adjacent side walls 22 and 23 of the two containers and the opposite side walls 24 and 25 are arranged parallel to each other, the perpendicular to them side walls 26 and 27 or 28 and 29 run obliquely towards each other from top to bottom, so that taper the containers downwards.

Die dem Gehäuse benachbarten Seitenwände 27 und 29 verlaufen dabei parallel zu der Seitenwand 13 des Gehäuses in geringem Abstand von dieser Seitenwand.The side walls 27 and 29 adjacent to the housing run parallel to the side wall 13 of the housing at a short distance from this side wall.

In die der Seitenwand 13 zugewandten Seitenwände 27 und 29 sind von oben her rechteckförmige Ausnehmungen 30 eingearbeitet, in die von oben her Einschübe 31 bzw. 32 einsetzbar sind. Diese Einschübe weisen dazu eine längs ihres Randes verlaufende Nut 33 auf, in die die Seitenwand 27 bzw. 29 eingreift. Die senkrechten Teile dieser Nut 33 bilden dabei eine Gleitführung für die Einschübe, so daß diese in einfachster Weise eingesetzt werden können.Rectangular recesses 30 are machined into the side walls 27 and 29 facing the side wall 13, into which slots 31 and 32 can be inserted from above. For this purpose, these inserts have a groove 33 running along their edge, into which the side wall 27 or 29 engages. The vertical parts of this groove 33 form a sliding guide for the inserts, so that they can be used in the simplest way.

Während die beiden Behälter vollständig identisch ausgebildet sind, unterscheiden sich die beiden Einschübe 31 und 32. Der Einschub 31 ist für den Reinigungsflüssigkeitsbehälter bestimmt und weist eine Öffnung 34 auf, an die sich nach innen ein zum Boden des Behälters führendes Rohrstück 35 anschließt.While the two containers are completely identical, the two inserts 31 and 32 differ. The insert 31 is intended for the cleaning liquid container and has an opening 34, which is followed by a pipe section 35 leading to the bottom of the container.

Der Einschub 32 ist für den Schmutzfangsbehälter bestimmt, er weist zwei Öffnungen 36 und 37 auf, wobei sich an die erste Öffnung 36 ein horizontales Rohrstück 38 anschließt, über welches ein Staubfangbeutel 39 gezogen werden kann. An die andere Öffnung 37 schließt sich ebenfalls ein horizontales Rohrstück 40 an, welches an seinem offenen Ende von einem Faltenfilter 41 überfangen ist.The insert 32 is intended for the dirt collecting container, it has two openings 36 and 37, a horizontal tube piece 38 adjoining the first opening 36, via which a dust bag 39 can be pulled. At the other opening 37 there is also a horizontal pipe section 40 which is covered by a pleated filter 41 at its open end.

Die Öffnungen 34, 36 und 37 sind so angeordnet, daß sie bei auf die Bodenplatte 2 aufgesetzten Behältern mit den Öffnungen 14 bzw. 12 bzw. 16 ausgerichtet sind. Um hier eine dichte Verbindung zwischen den Leitungsstücken im Gehäuse und den entsprechenden Leitungsstükken in den Behälter herzustellen, sind in die Seitenwand 13 die Öffnungen 12 und 16 umgebende Ringnuten 42 eingearbeitet, in die elastische Ringdichtungen 43 eingelegt sind, die teilweise aus den Ringnuten 42 hervorstehen. Der Einschub 32 weist in seinem die Öffnungen 36 und 37 umgebenden Bereich ebene Dichtflächen 44 auf, die gegen die Ringdichtungen gedrückt werden und somit dichtend an ihnen anliegen.The openings 34, 36 and 37 are arranged such that they are aligned with the openings 14, 12 and 16, respectively, when containers are placed on the base plate 2. In order to establish a tight connection here between the line pieces in the housing and the corresponding line pieces in the container, ring grooves 42 surrounding openings 12 and 16 are incorporated into side wall 13, into which elastic ring seals 43 are inserted, which partially protrude from ring grooves 42. In its area surrounding the openings 36 and 37, the insert 32 has flat sealing surfaces 44 which are pressed against the ring seals and thus bear against them in a sealing manner.

Um den entsprechenden Anpreßdruck zu erzeugen, ist jeder Behälter mit einem um eine horizontale Achse verschwenkbaren, U-förmigen Tragegriff 45 versehen, der auf seiner von einem Griffstück 46 abgewandten Seite der Drehachse hakenförmige Spannelemente 47 trägt. In einer ersten Stellung, bei der der Tragegriff 45 senkrecht nach oben vom Behälter absteht, ist er als Tragegriff für den jeweiligen Behälter benutzbar, die Spannelemente 47 stehen dabei nach unten und haben keine Wirkung.In order to generate the corresponding contact pressure, each container is provided with a U-shaped carrying handle 45 which can be pivoted about a horizontal axis and which carries hook-shaped clamping elements 47 on its side of the axis of rotation facing away from a handle 46. In a First position, in which the handle 45 protrudes vertically upward from the container, it can be used as a handle for the respective container, the clamping elements 47 are down and have no effect.

Schwenkt man den Tragegriff 45 nach dem Aufsetzten des Behälters auf die Bodenplatte 2 jedoch in die in Figur 1 dargestellte horizontale Lage, greifen die Spannelemente 47 in eine Quernut 48 am oberen Ende der Seitenwand 13 des Gehäuses 3 ein und hintergreifen einen an der Oberkante der Quernut 48 angeordneten, nach unten vorstehenden, leitstenförmigen Vorsprung 49. Die Kontaktfläche der Spannelemente 47 und des Vorsprungs 49 sind derart schräg ausgebildet, daß beim Verschwenken des Tragegriffs 45 in die zweite, liegende Stellung der Behälter zunehmend kräftiger gegen das Gehäuse 3 gespannt wird, so daß durch diese Spannung einerseits die Behälters in ihrer Position am Gerät fixiert werden, während andererseits die Dichtflächen 44 dichtend gegen die Ringdichtungen 43 am Gehäuse gepreßt werden.However, if the carrying handle 45 is pivoted after the container has been placed on the base plate 2 into the horizontal position shown in FIG. 1, the clamping elements 47 engage in a transverse groove 48 at the upper end of the side wall 13 of the housing 3 and engage behind on the upper edge of the transverse groove 48 arranged, protruding downward, lead-shaped projection 49. The contact surface of the clamping elements 47 and the projection 49 are formed obliquely so that when the handle 45 is pivoted into the second, lying position of the container, the container 3 is increasingly tightened so that This tension on the one hand fixes the container in position on the device, while on the other hand the sealing surfaces 44 are pressed sealingly against the ring seals 43 on the housing.

. Der Tragegriff 45 liegt in seiner zweiten Stellung an der Oberseite eines den Behälter verschließenden Deckels 50 an, vorzugsweise in einer speziell zur Aufnahme des Tragegriffs ausgebildeten Vertiefung 51 desselben. Dadurch wird der Dekkel 50 auf der Oberseite des Behälters festgelegt, so daß der Behälter auch an seiner Oberseite dicht verschlossen ist. Verschwenkt man den Tragegriff in seine erste, nach oben abstehende Stellung, kann der Deckel 50 ohne weiteres vom Behälters abgenommen werden.. In its second position, the carrying handle 45 lies against the top of a lid 50 closing the container, preferably in a recess 51 of the same which is specially designed to hold the carrying handle. As a result, the lid 50 is fixed on the top of the container, so that the container is also tightly closed on its top. If the pivoting handle is pivoted into its first, upwardly projecting position, the cover 50 can easily be removed from the container.

Der Deckel seinerseits drückt in verschlossenem Zustand den jeweiligen Einschub 31 oder 32 in die zugehörige Ausnehmung 30 ein und fixiert den Einschub in dieser Lage. Um auch hier eine einwandfreie Abdichtung zu erzielen, kann sich am Boden der Nut 33 der Einschübe 31. und 32 eine in der Zeichnung nicht dargestellte elastische Dichtung befinden, die beim Eindrücken der Einschübe dichtend an den Seitenwänden 27 bzw. 29 anliegt.The cover, in turn, presses the respective insert 31 or 32 into the associated recess 30 in the closed state and fixes the insert in this position. In order to achieve a perfect seal here, too, an elastic seal (not shown in the drawing) can be located on the bottom of the groove 33 of the inserts 31 and 32, which rests sealingly on the side walls 27 and 29 when the inserts are pressed in.

Auf diese Weise hat der Tragegriff eine Mehrfachfunktion. Er dient in ausgeschwenktem Zustand zum Tragen des Behälters, er spannt den Behälter im liegenden Zustand gegen das Gehäuse und stellt somit dichte Verbindungen zwischen den einzelnen Leitungen des Gehäuses und der Behälter her, er sichert aber auch den Deckel in der verschlossenen Stellung und drückt damit indirekt die Einschübe in die Ausnehmungen der Behälter ein.In this way, the handle has a multiple function. It serves to carry the container in the swung-out state, it tensions the container against the housing in the lying state and thus creates tight connections between the individual lines of the housing and the container, but it also secures the lid in the closed position and thus presses indirectly insert the slots into the recesses in the containers.

Der Benutzer kann allein durch Verschwenken dieses Tragegriffes die auf die Bodenplatte 2 aufgesetzten Behälter dort festlegen und für alle Arbeitsfunktionen betriebsbereit anschließen, ohne daß dazu irgendein weiterer Handgriff notwendig wäre. Umgekehrt können alle diese Verbindungen allein durch Verschwenken des Tragegriffs in die erste Stellung gelöst werden, wobei dann der Tragegriff sofort zum Abnehmen des Behälters verwendet werden kann. Dieses Abnehmen des Behälters wird im übrigen noch durch eine taschenförmige Einformung 52 in den Seitenwänden 26 und 28 unterstützt.The user can fix the container placed on the base plate 2 there simply by pivoting this handle and connect it ready for all work functions without any further manipulation being necessary. Conversely, all of these connections can be released by simply pivoting the handle into the first position, in which case the handle can be used immediately to remove the container. This removal of the container is further supported by a pocket-shaped indentation 52 in the side walls 26 and 28.

Beim normalen Betrieb des Gerätes als Trokkensauger wird nur der Behälter 22 verwendet, in dem Behälter 21 können die Ersatzteile untergebracht werden, die für den Sprühextraktionsbetrieb notwendig sind. Der Behälter 22 wirkt dabei wie ein konventioneller Schmutzauffangbehälter, der Schmutz wird entweder in dem Staubfangbeutel 39 oder unmittelbar im Behälter 22 aufgefangen, wenn ein solcher Staubfangbeutel nicht vorhanden, ist, beispielsweise beim Naßsaugbetrieb.During normal operation of the device as a dry vacuum cleaner, only the container 22 is used; the spare parts that are necessary for the spray extraction operation can be accommodated in the container 21. The container 22 acts like a conventional dirt collecting container, the dirt is collected either in the dust collecting bag 39 or directly in the container 22 if such a dust collecting bag is not present, for example during wet suction operation.

Wird Sprühextraktionsbetrieb gewünscht, wird der Behälter 21 mit Reinigungsflüssigkeit gefüllt, die in ihm vorher aufbewahrten Teile, beispielsweise die Sprühleitung und eine Sprühdüse, werden am Saugschlauch 8 und an einem in der Zeichnung nicht dargestellten Saugkopf befestigt. Durch Einschalten der Förderpumpe 6 wird Reinigungsflüssigkeit aus dem Behälter 21 über die Sprühleitung gegen die zu reinigende Fläche gefördert, von dort wird sie über die Saugleitung zusammen mit dem gelösten Schmutz in den Behälter 22 gefördert, in dem die verschmutzte Reinigungsflüssigkeit gesammelt wird. Nach Beendigung des Arbeitsvorganges können die Behälter in einfachster Weise vom Reinigungsgerät abgenommen werden, wobei es dann auch günstig ist, die Einschübe aus den Seitenwänden herauszunehmen, damit einerseits die Entleerung bzw. Reinigung der Behälter vereinfacht wird, andererseits um bei den Leitungsstücken im Behälter 22 die Filter reinigen bzw. den Staubfangbeutel auswechseln zu können.If spray extraction operation is desired, the container 21 is filled with cleaning liquid, the parts previously stored in it, for example the spray line and a spray nozzle, are attached to the suction hose 8 and to a suction head (not shown in the drawing). By switching on the feed pump 6, cleaning liquid is conveyed from the container 21 via the spray line against the surface to be cleaned, from there it is conveyed via the suction line together with the loosened dirt into the container 22, in which the dirty cleaning liquid is collected. After completion of the work process, the containers can be removed from the cleaning device in the simplest manner, it then also being advantageous to remove the inserts from the side walls, so that on the one hand the emptying or cleaning of the containers is simplified, and on the other hand, in the case of the line pieces in the container 22 Clean the filter or be able to change the dust bag.
