The housing covers the fluid application device (3) in an arc formation. The fluid application device is secured in the arc interior, to at least one slide (25), which penetrates the housing (15). On the upper side of the housing, the slide is formed as a handle (26) for position adjustment. The suction mouth is divided crossways to its longitudinal extent into individual suction sections, which in the suction direction issue into a common suction chamber (53).

Description

Die Erfindung betrifft ein Sauggerätevorsatz zur Feuchtreinigung von Flächen, insbesondere von senkrechten Flächen, mit einer Flüssigkeitsauftragsvorrichtung.The invention relates to a suction device attachment for the wet cleaning of surfaces, in particular of vertical surfaces, with a liquid application device.

Reinigungsgeräte zur Feuchtreinigung von Flächen, insbesondere von senkrechten Fensterflächen, sind in einer Vielzahl von Variationen bekannt. Sie bestehen zumeist aus einem Sauggerät, welches neben einer Saugvorrichtung auch über einen Vorratsbehälter für die Reinigungsflüssigkeit verfügt. Druckbeaufschlagt wird die Reinigungsflüssigkeit von dem Sauggerät über eine Druckleitung dem eigentlichen Reinigungsgerätevorsatz zugeführt und dort über Düsen, Bürsten, Schwämme oder dergleichen auf die zu reinigende Fläche aufgetragen. Die aufgetragene Flüssigkeit wird dann von dem Sauggerät über eine häufig schlitzförmige Saugmündung und den daran anschließenden Saugkanal wieder aufgesaugt. Derartige Reinigungsgeräte sind zumeist als Industriegeräte ausgelegt und dementsprechend voluminös und teuer und für den üblichen Hausgebrauch auch nicht geeignet.Cleaning devices for the wet cleaning of surfaces, in particular of vertical window surfaces, are known in a large number of variations. They usually consist of a suction device, which in addition to a suction device also has a reservoir for the cleaning fluid. Pressurized, the cleaning liquid is supplied from the suction device via a pressure line the actual Reinigungsgerätevorsatz and applied there via nozzles, brushes, sponges or the like on the surface to be cleaned. The applied liquid is then absorbed by the suction device via a frequently slot-shaped suction mouth and the adjoining suction channel again. Such cleaning devices are usually designed as industrial equipment and therefore bulky and expensive and not suitable for normal household use.

Aus der EP 0 243 323 ist ein Reinigungsgerät bekannt, bei welchem eine Flüssigkeitsauftragsvorrichtung mit einer Reinigungsflüssigkeit bzw. dort einem Reinigungsdampf über eine Druckleitung versorgt wird. Zum Auftragen der Reinigungsflüssigkeit auf die zu reinigende Fläche ist die dortige Flüssigkeitsauftragsvorrichtung mit einem Schwamm versehen, der innerhalb eines Saugglockengehäuses um eine zu der zu reinigenden Fläche parallele Achse in eine Arbeitslage verschwenkbar angeordnet ist. Parallel zur Längserstreckung des Schwammes bzw. seiner Achse und damit quer zur üblichen Arbeitsrichtung ist weiter eine schlitzförmige Saugmündung oberhalb der zu reinigenden Fläche, mit einer Dichtlippe auf dieser lediglich aufsitzend, angeordnet. Saugglockengehäuse und Saugmündung stehen mit einem Absaugkanal in Verbindung, innerhalb dem auch die Druckleitung für die Zuführung der Reinigungsflüssigkeit angeordnet ist. Reinigungsgerätevorsatz und das Reinigungsgerät bilden hier funktionstechnisch eine Einheit und können voneinander nicht isoliert verwendet werden. In der -nicht vorveröffentlichten- WO 96/01614 ist ein Sauggerätevorsatz zur Feuchtreinigung von Flächen beschrieben, welcher als bevorzugt auch im Sinne dieser Erfindung als Vorsatzgerät reiner Sauggeräte, bspw. auch Haushaltssauggeräte, Verwendung findet. Es ist dort wie hier von Bedeutung, daß eine Druckzuleitung von dem Sauggerät zur Flüssigkeitsauftragsvorrichtung entfallen kann und das Sauggerät allein über die Möglichkeit eines Absaugens verfügt, also keine Tankanlage und Druckanlage insbesondere für die Reinigungsflüssigkeit enthält. Es zu diesem Zweck die Flüssigkeitsauftragsvorrichtung des beschriebenen Sauggerätevorsatzes mit einem eigenen Reinigungsflüssigkeitstank versehen, eine gesonderte Zuleitung der Reinigungsflüssigkeit kann damit entfallen. Ferner wird dort eine Lageverstellbarkeit der Flüssigkeitsauftragsvorrichtung gezeigt, wozu die Flüssigkeitsauftragsvorrichtung mit einem ringförmigen Verbindungselement das Saugkanalgehäuse umgreift und auf diesem axial gegen die Kraft einer offenliegenden, das Saugkanalgehäuse gleichfalls umschließenden Feder geführt wird. Eine solche offenliegende Führung ist hinsichtlich einer Verschmutzung anfällig und birgt außerdem durch ihre gute Zugänglichkeit die Gefahr einer Verletzung.From EP 0 243 323 a cleaning device is known in which a liquid application device is supplied with a cleaning liquid or there a cleaning vapor via a pressure line. For applying the cleaning liquid to the surface to be cleaned, the local liquid application device is provided with a sponge, which is arranged within a suction cup housing about an axis parallel to the surface to be cleaned in an operating position pivotable. Parallel to the longitudinal extent of the sponge or its axis and thus transversely to the usual working direction is still a slot-shaped suction mouth above the surface to be cleaned, with a sealing lip on this only sitting, arranged. Suction cup housing and suction mouth communicate with a suction channel, within which the pressure line for the supply of cleaning liquid is arranged. Reinigungsgerätevorsatz and the cleaning device form functionally one unit and can not be used separately from each other. WO 96/01614 describes a suction device attachment for the wet cleaning of surfaces, which is also preferably used in the sense of this invention as an attachment of pure suction devices, for example also household suction devices. It is as important here that a pressure supply from the suction device to the liquid application device can be omitted and the suction device alone has the possibility of suction, so no tank system and pressure system contains in particular for the cleaning liquid. It provided for this purpose, the liquid application device of the described Sauggerätevorsatzes with its own cleaning liquid tank, a separate supply of cleaning fluid can be dispensed with. Furthermore, a positional adjustability of the liquid application apparatus is shown there, for which purpose the liquid application apparatus surrounds the suction channel housing with an annular connecting element and is guided axially against the force of an exposed spring which likewise encloses the suction channel housing. Such an open guide is susceptible to contamination and also carries the risk of injury due to its good accessibility.

Im Saugkanal dieses Sauggerätevorsatzes ist ferner ein feuchtigkeitsabsorbierendes Filter vorgesehen, welches dem abgesaugten Flüssigkeits-Luftgemisch Feuchtigkeit entzieht und speichert. Es ist durch diese Merkmal eine weitere konstruktive Maßnahme von grundlegender Bedeutung bei Verwendung von Haushaltsstaubsaugern verwirklicht, nämlich die Phasentrennung des abgesaugten Flüssigkeits-Luftgemisches. Dies ist bei der Verwendung von üblichen Haushaltsstaubsaugern aufgrund deren elektrischer Konstruktion und Saugtechnik schon aus Sicherheitsgründen notwendig. Eine solche auf Filterwirkung basierende Phasentrennung steht jedoch einer üblichen Saugtechnik auch aufgrund der großen auftretenden Druckverluste an dem Filter grundsätzlich entgegen. Insbesondere dann, wenn eine weitere, für die gasförmige Phase permeable Membran noch vorgesehen ist, welche die flüssige Phase bei Überschreiten der Aufnahmefähigkeit des die flüssige Phase speichernden Filtermaterials die dann austretenden Flüssigkeit noch abhält.In the suction channel of this Sauggerätevorsatzes a moisture-absorbing filter is also provided, which Absorbs and stores moisture from the extracted liquid-air mixture. It is realized by this feature another constructive measure of fundamental importance in the use of household vacuum cleaners, namely the phase separation of the extracted liquid-air mixture. This is necessary in the use of conventional household vacuum cleaners due to their electrical design and suction for safety reasons. However, such a phase separation based on filter action is fundamentally contrary to a conventional suction technique, also due to the large pressure losses occurring at the filter. In particular, when a further, permeable to the gaseous phase membrane is still provided, which still holds the liquid phase at exceeding the capacity of the liquid phase storing the filter material, the liquid then exiting.

Von daher stellt sich die technische Problematik, ein Sauggerätevorsatz zur Feuchtreinigung von Flächen handhabungssicher und betriebssicher, insbesondere für eine Verwendung mit üblichen Haushaltsstaubsaugern zu gestalten.Therefore, the technical problem arises, a Sauggerätevorsatz for wet cleaning of surfaces safe to handle and reliable, especially for use with conventional household vacuum cleaners to make.

Diese technische Problematik ist beim Gegenstand des Anspruches 1 gelöst. Dabei stellt der Anspruch 1 auf ein Sauggerätevorsatz ab, bei dem die Flüssigkeitsauftragsvorrichtung gegen ein gesondert ausgebildetes Saugkanalgehäuse lageverstellbar ist, in welchem ein in einer schlitzförmigen Saugmündung auslaufender Saugkanal angeordnet ist, wobei das Saugkanalgehäuse die Flüssigkeitsauftragsvorrichtung bogenförmig überdeckend angeordnet ist und im Bogeninneren die Flüssigkeitsauftragsvorrichtung an wenigstens einem Schieber gefangen ist, welcher das Saugkanalgehäuse durchsetzt und oberseitig des Saugkanalgehäuses als Handhabe zum Verstellen der Lage ausgebildet ist. Infolge dieser konstruktiven Merkmale ist zunächst die Flüssigkeitsauftragsvorrichtung bogenförmig -zumindest teilweise- von dem Gehäuse des Saugkanals, welches gesondert von der Flüssigkeitsauftragsvorrichtung ausgebildet ist, überdeckt und damit auch geschützt. Es ist aber durch die gesonderte Ausbildung des Saugkanalgehäuses und der Flüssigkeitsauftragsvorrichtung letztere ein im wesentlichen eigenständiges Bauteil, was leicht bspw. ersetzt oder von dem Gehäuse getrennt werden kann, um Reinigungstücher, Borsten oder dergleichen bspw. zu ersetzen. Im Bogeninneren, d.h. mit Bezug auf eine Gebrauchslage zwischen der zu reinigenden Fläche und dem die Flüssigkeitsauftragsvorrichtung überdeckenden Saugkanal, ist die Flüssigkeitsauftragsvorrichtung an wenigstens einem Schieber gefangen. Es ist dies ggf. eine lösbare Verbindung oder ist der Schieber selbst von dem Saugkanalgehäuse lösbar, welches er durchsetzt, um oberseitig des Sauggehäuses als Handhabe zum Verstellen der Lage ausgebildet zu sein. Die eingangs erwähnten unterschiedlichen Gebrauchslagen der Flüssigkeitsauftragsvorrichtung werden demgemäß nicht mehr durch eine Betätigung seitlich des Sauggerätevorsatzes angeordneter Drehknöpfe oder dergleichen gemäß der EP 0 243 323 eingestellt, welche sich insbesondere an einem Fensterrahmen oder einer Ecke als äußerst störend erweisen. Gleichfalls ist Handhabung und Sicherheit gegenüber dem in der WO 96/01614 beschriebenen Sauggerätevorsatz deutlich verbessert.This technical problem is solved in the subject matter of claim 1. In this case, the claim 1 is based on a Sauggerätevorsatz, wherein the liquid application device is positionally adjustable against a separately formed Saugkanalgehäuse in which a projecting in a slot-shaped suction mouth suction channel is arranged, the Saugkanalgehäuse the liquid application device is arranged arcuately overlapping and inside the sheet the liquid application device at least one Slide is trapped, which passes through the Saugkanalgehäuse and the upper side of the Saugkanalgehäuses is designed as a handle for adjusting the position. As a result of these constructive features, the liquid application device is initially arcuate-at least partially-covered by the housing of the suction channel, which is formed separately from the liquid application device, and thus also protected. But it is due to the separate design of the Saugkanalgehäuses and the liquid application device latter an essentially independent component, which can be easily. For example, replaced or separated from the housing to cleaning cloths, bristles or the like, for example, to replace. In the sheet interior, ie with respect to a position of use between the surface to be cleaned and the liquid application device covering the suction channel, the liquid application device is trapped on at least one slider. This is possibly a detachable connection or the slider itself is detachable from the Saugkanalgehäuse, which he passes through to be formed on the upper side of the suction housing as a handle for adjusting the position. The above-mentioned different operating positions of the liquid application device are accordingly no longer adjusted by an actuation laterally of Sauggerätsvorsatzes arranged rotary knobs or the like according to EP 0243323, which prove to be particularly disturbing especially on a window frame or corner. Likewise, handling and safety is significantly improved over the Sauggeräte intent described in WO 96/01614.

Wie bereits angesprochen, ist eine Lageveränderung der Flüssigkeitsauftragvorrichtung vorgesehen, bspw. von einer inaktiven Lage mit nur einer Abzieh- und/oder Absaugfunktion des Sauggerätevorsatzes ohne Flüssigkeitsauftrag in eine Gebrauchslage mit einem Absaugen der aufgebrachten Reinigungsflüssigkeit und einer weiteren Lage, in welcher lediglich Reinigungsflüssigkeit aufgebracht wird und ein Absaugen und/oder Abziehen nicht erfolgt. Für eine solche Lageänderung ist im Bogeninneren eine Führung angeordnet, in der die Flüssigkeitsauftragvorrichtung schiebergesteuert linear verschieblich ist. Trotz der bogenförmigen Überdeckung der Flüssigkeitsauftragsvorrichtung durch insbesondere ein gesondert ausgebildetes Saugkanalgehäuse wird eine lineare Verschieblichkeit bevorzugt, da hierfür eine Führung einfach auszubilden ist. Dabei wird bevorzugt, daß -mit Bezug auf eine Anlage des Sauggerätevorsatzes in Gebrauchslage an eine zu reinigende Fläche- die Verschiebung der Flüssigkeitsauftragsvorrichtung aus einer hinter die Saugmündung zurückgezogenen inaktiven Lage durch die Kraft einer Feder in eine mittlere Arbeitslage erfolgt, in welcher die Flüssigkeitsauftragsvorrichtung frei von dem Schieber gegen die Kraft der Feder beweglich ist, und aus der schiebergesteuert die Flüssigkeitsauftragsvorrichtung in eine der Saugmündung vorstehende Lage gebracht werden kann, in der sie über den Schieber gegen das Saugkanalgehäuse in Verschieberichtung abgestützt ist. Es können zwei Schieber mit Bezug auf die bevorzugte Arbeitsrichtung quer dazu an den Enden der Flüssigkeitsauftragsvorrichtung vorgesehen sein. Bevorzugt wird jedoch eine zentrale Ausbildung nur eines einzigen Schiebers, der dann das Saugkanalgehäuse etwa mittig durchsetzt, wobei dann der Schieber und ggf. die Führung zwischen Saugrohrverzweigungen angeordnet sind. Damit wird der Saugkanal selbst nicht durchsetzt und Dichtungsprobleme oder dergleichen entfallen.As already mentioned, a change in position of the liquid application device is provided, for example. From an inactive position with only a Abzieh- and / or Absaugfunktion the Sauggerätevorsatzes without liquid application in a position of use with a suction of the applied cleaning liquid and a further layer in which only cleaning liquid is applied and suction and / or removal does not take place. For such a change in position, a guide is arranged in the sheet inside, in which the liquid application device is slider-controlled linearly displaceable. Despite the arcuate overlap of the liquid application device by a particular specially designed Saugkanalgehäuse a linear displaceability is preferred, since this is a guide is easy to train. It is preferred that - with respect to a system of Sauggerätsvorsatzes in the position of use to a surface to be cleaned- the displacement of the liquid application device a withdrawn behind the suction port inactive position by the force of a spring in a middle work position in which the liquid application device is free of the slider movable against the force of the spring, and from the slider-controlled the liquid application device can be brought into a projecting position of the suction mouth, in which it is supported via the slide against the Saugkanalgehäuse in the direction of displacement. There may be two slides with respect to the preferred working direction transverse thereto at the ends of the liquid applicator. Preferably, however, a central training only a single slider, which then passes through the Saugkanalgehäuse approximately centrally, in which case the slide and possibly the guide between Saugrohrverzweigungen are arranged. Thus, the suction channel itself is not penetrated and sealing problems or the like omitted.

Die Erfindung wird anhand der Zeichnung näher erläutert, in der lediglich mehrere Ausführungsbeispiele dargestellt sind.The invention will be explained in more detail with reference to the drawing, in which only several embodiments are shown.

die Flüssigkeitsauftragsvorrichtung in einer der Saugmündung vorstehenden Gebrauchslage, in welcher lediglich Reinigungsflüssigkeit aufgetragen wird, diese jedoch nicht abgesaugt wird,the liquid application device in a position of use projecting the suction orifice, in which only cleaning liquid is applied, but this is not sucked off,

Fig. 1 zeigt einen Sauggerätevorsatz 1 in einem Längsschnitt senkrecht zu einer zu reinigenden Fläche 2, mit einer Flüssigkeitsauftragsvorrichtung 3 in einer federnd abgestützen Arbeitslage.Fig. 1 shows a Sauggerätsvorsatz 1 in a longitudinal section perpendicular to a surface to be cleaned 2, with a liquid applicator 3 in a spring-supported working position.

Die Flüssigkeitsauftragsvorrichtung 3 weist einen eigenen Tank 4 für eine weiter nicht dargestellte Reinigungsflüssigkeit auf. Durch diese Maßnahme kann auf eine Druckzuführungsleitung für die Reinigungsflüssigkeit von einem Sauggerät her verzichtet werden. Hierdurch wird eine der Grundvoraussetzungen geschaffen, den Sauggerätevorsatz 1 in Verbindung mit üblichen Haushaltsstaubsaugern bspw. zu verwenden. Eine Kapillarvorrichtung, hier eine Borstenreihe 5, die in den Tank 4 hineinragt und sich auf einer Querplatte 6 abstützt, sorgt durch den Kapillareffekt für ein langsames, gleichmäßiges Austreten der Reinigungsflüssigkeit letztlich auf die zu reinigende Fläche 2. Die Borstenreihe 5 ist beispielhaft um einen Winkel von etwa 45° gegenüber der zu reinigenden Fläche 2 angestellt, wodurch einer solchen Borstenreihe 5 auch ein guter mechanischer Reinigungseffekt vergleichbar einem Schaben zukommt. Nach dem Austreten aus den zwischen den einzelnen Borsten ausgebildeten Kapillaren benetzt die Reinigungsflüssigkeit die Rückseite eines über die Borstenreihe 5 angeordneten Reinigungstuchs 7, welches senkrecht zur üblichen Arbeitsrichtung, dargestellt durch den Doppelpfeil 8, randseitig in Fassungen 9 der Flüssigkeitsauftragsvorrichtung 3 eingespannt ist. Dazu ist hier das Reinigungstuch 7, bspw. ein Mikrovlies, selbst randseitig insbesondere an den Rändern quer zur Arbeitsrichtung 8, mit Rahmenwangen 16 hier von rundem Querschnitt verbunden. Die Rahmenwangen 16 werden in hinterschnittene Ausnehmungen 17 des Gehäuses der Flüssigkeitsauftragsvorrichtung 3 eingeklipst.The liquid application device 3 has its own tank 4 for a cleaning liquid, not further shown. By this measure, it is possible to dispense with a suction line for the cleaning fluid from a suction device. As a result, one of the basic conditions is created to use the Sauggerätevorsatz 1 in conjunction with conventional household vacuum cleaners, for example. A capillary device, here a row of bristles 5, which projects into the tank 4 and is supported on a transverse plate 6, ensures by the capillary effect for a slow, uniform emergence of the cleaning liquid ultimately on the surface to be cleaned 2. The row of bristles 5 is an example by an angle is made of about 45 ° relative to the surface to be cleaned 2, whereby such a bristle row 5 also has a good mechanical cleaning effect comparable to a cockroaches. After emerging from the capillaries formed between the individual bristles, the cleaning liquid wets the back side of a cleaning cloth 7 arranged above the row of bristles 5, which is clamped peripherally in sockets 9 of the liquid application apparatus 3 perpendicular to the usual working direction, represented by the double arrow 8. For this purpose, here is the cleaning cloth 7, for example. A micro-fleece, even at the edges especially at the edges transversely to the working direction 8, with frame cheeks 16 here of round cross-section connected. The frame cheeks 16 are clipped into undercut recesses 17 of the housing of the liquid application device 3.

Die Flüssigkeitsauftragsvorrichtung 3 ist in Doppelpfeilrichtung 10 in der in Fig. 1 gezeigten Arbeitslage gegen die Kraft einer Feder 11 verschiebbar, die hier als Druckfeder ausgebildet auf einem Zapfen 12 aufsitzt. Anderenends stützt sich die Feder 11 auf einem Zapfen 13 auf einer Halteplatte 14 eines Saugkanalgehäuses 15 ab.The liquid application device 3 is displaceable in the double arrow direction 10 in the working position shown in FIG. 1 against the force of a spring 11, which is designed here as a compression spring and is mounted on a pin 12. At the other end, the spring 11 is supported on a pin 13 on a retaining plate 14 of a Saugkanalgehäuses 15.

Innerhalb des Saugkanalgehäuses 15 ist ein Saugkanal 20 angeordnet, wobei hier als Saugkanal 20 auch die gesamte Ableitung eines von der zu reinigenden Fläche 2 abgesaugten Flüssigkeits-Luftgemisches von einer Saugmündung 21 bis hin über einen Saugschlauch 22 zu einem hier nicht dargestellten Sauggerät, bspw. einem üblichen Haushaltsstaubsauger verstanden wird.Within the Saugkanalgehäuses 15, a suction channel 20 is arranged, in which case as the suction channel 20 and the entire discharge of a sucked from the surface to be cleaned 2 liquid-air mixture from a suction mouth 21 through a suction hose 22 to a suction device, not shown., For example usual household vacuum cleaner is understood.

Die Saugmündung 21 ist, wie Fig. 1 zeigt, im wesentlichen schlitzförmig und parallel in ihrer Gesamterstreckung zu der Flüssigkeitsauftragsvorrichtung 3 ausgebildet, d.h. im wesentlichen quer zur üblichen Arbeitsrichtung 8.The suction port 21 is, as shown in FIG. 1, formed substantially slit-shaped and parallel in its total extension to the liquid application device 3, i. essentially transversely to the usual working direction 8.

Das den in der schlitzförmigen Saugmündung 21 auslaufenden Saugkanal 20 aufnehmende Saugkanalgehäuse 15 überdeckt bogenförmig die Flüssigkeitsauftragsvorrichtung 3 über einen Winkel von ca. 70°. In den Randbereichen quer zur Arbeitsrichtung 8 kann gleichfalls eine Überdeckung durch das Saugkanalgehäuse 15 erfolgen, jedoch bleiben diese Bereiche bevorzugt von einer Überdeckung frei und können diese ggf. mit senkrecht zur Fläche 2 stehenden Reinigungsflächen in Anlage an bspw. einen Fensterrahmen oder dergleichen gebracht werden.The suction channel housing 15 receiving the suction channel 20, which terminates in the slot-shaped suction mouth 21, covers in an arc shape the liquid application device 3 over an angle of approximately 70 °. In the edge regions transversely to the working direction 8, an overlap can also take place through the suction channel housing 15, but these areas preferably remain free of an overlap and can if necessary be perpendicular to the surface 2 standing cleaning surfaces in contact with, for example, a window frame or the like.

Innerhalb des Bogens ist die Flüssigkeitsauftragsvorrichtung 3 an einem hier zentral ausgebildeten Schieber 25 gefangen, der das Saugkanalgehäuse 15 durchsetzt und oberseitig des Saugkanalgehäuses 15 als Handhabe 26 zum Verstellen der Lage der Flüssigkeitsauftragsvorrichtung 3 gemäß der Figuren 4, 6, 9 ausgebildet. Der Schieber 25 ist im wesentlichen streifenförmig ausgebildet und weist eine Umbiegung 27 von 180° auf, so daß nach Art einer vorstehenden Blattfeder die Handhabe 26 niederdrückbar ist. Durch dieses Niederdrücken wird ein Riegel 28 aus der in Fig. 1 gezeigten verriegelten Lage in einer mittleren von drei Ausnehmungen 29 gebracht und ist dann innerhalb eines Schlitzes 30 im Saugkanalgehäuse 15 verschiebbar. Durch den Eingriff des Riegels 28 in eine der Ausnehmungen 29 können damit drei Schieberstellungen rastgesichert werden.Within the sheet, the liquid application device 3 is trapped on a slider 25 which is centrally formed here and passes through the suction channel housing 15 and on the upper side of the suction channel housing 15 as a handle 26 for adjusting the position of the liquid application device 3 according to FIGS. 4, 6, 9. The slider 25 is formed substantially strip-shaped and has a bend 27 of 180 °, so that the handle 26 can be depressurized in the manner of a protruding leaf spring. By this depression, a latch 28 is brought from the locked position shown in Fig. 1 in a middle of three recesses 29 and is then slidable within a slot 30 in the suction channel 15. The engagement of the bolt 28 in one of the recesses 29 so that three slide positions can be rest assured.

Fig. 4 zeigt in einem gegenüber Fig. 1 im Bereich der Saugmündung 21 versetzten Schnitt die Handhabe 26 in einer zurückgeschobenen Position. Hierbei ist über den Schieber 25 auch die Flüssigkeitsauftragsvorrichtung 3 in eine hinter die Saugmündung 21 zurückgezogene, inaktive Lage gegen die Kraft der Feder 11 gebracht. In dieser inaktiven Lage steht die Saugmündung 21 lediglich mit einer Dichtlippe 31 auf der zu reinigenden Fläche 2 auf und kann mittels der Dichtlippe 31 aufgetragene Reinigungsflüssigkeit bspw. abgezogen und/oder auch aufgesaugt werden. Ein Auftrag von Reinigungsflüssigkeit findet jedoch nicht statt.Fig. 4 shows in a comparison with FIG. 1 in the region of the suction mouth 21 offset section the handle 26 in a retracted position. Here, the liquid application device 3 is brought into a retracted behind the suction port 21, inactive position against the force of the spring 11 via the slider 25. In this inactive position, the suction orifice 21 is only with a sealing lip 31 on the surface to be cleaned 2 and can by means of the sealing lip 31 applied cleaning liquid, for example, deducted and / or sucked up. However, an order of cleaning liquid does not take place.

Um die Flüssigkeitsauftragsvorrichtung 3 in der in Fig. 4 gezeigten inaktiven Lage gegen die Kraft der Feder 11 an dem Saugkanalgehäuse 15 festlegen zu können, weist der Schieber 25 seitens der Flüssigkeitsauftragsvorrichtung 3 einen Mitnehmer 32 von hier rundem Querschnitt auf, welcher sich quer zur Arbeitsrichtung 8 erstreckt, vgl. Fig. 5. Es ist der Mitnehmer 32 in einer Führungsausnehmung 33 gafangen und dort im übrigen frei beweglich, vgl. auch die Figuren 6 und 7.To the liquid application device 3 in the inactive position shown in Fig. 4 against the force of the spring 11th To be able to determine the suction channel housing 15, the slider 25 on the part of the liquid application device 3 a driver 32 from here round cross-section, which extends transversely to the working direction 8, see. Fig. 5. It is the driver 32 in a guide recess 33 gafangen and there in the rest freely movable, see. also FIGS. 6 and 7.

In der inaktiven Lage gemäß Fig. 4 und 5 liegt der Mitnehmer 32 an einer Begrenzungsfläche 34 der Führungsausnehmung 33 an und verhindert durch seine Feststellung durch den Riegel 28 in der hinteren Ausnehmung 29 eine Beweglichkeit der Flüssigkeitsaufträgvorrichtung 3, in dem der Schieber 25 diese gegen das Saugkanalgehäuse 15 in Anlage hält.In the inactive position shown in FIGS. 4 and 5, the driver 32 is located on a boundary surface 34 of the guide recess 33 and prevented by its detection by the bolt 28 in the rear recess 29, a mobility of the liquid applicator 3, in which the slider 25 against the Suction channel housing 15 holds in contact.

Durch Niederdrücken der Handhabe 26 wird der Rastsitz des Riegels 38 in der hinteren Ausnehmung 29 gelöst und kann der Schieber 25 zur mittleren Ausnehmung 29 hin verschoben werden. Hierdurch gibt der Mitnehmer 32 die Begrenzungsfläche 34 frei und wird durch die Kraft der sich entspannenden Feder 11 die Flüssigkeitsauftragsvorrichtung 3 in eine mittlere Arbeitslage gemäß Fig. 1 bzw. Fig. 6 und 7 gebracht. Es liegt nun der Mitnehmer 32 etwa mittig innerhalb der Führungsausnehmung 33, wodurch eine federnde Bewegung der Flüssigkeitsauftragsvorrichtung 3 in Doppelpfeilrichtung 10 ermöglicht ist, die durch die Begrenzungsflächen 34, 35 aber beschränkt wird. Die Verschiebung des Schiebers 25 kann geführt erfolgen, zu welchem Zweck seitliche, nicht dargestellte Führungsabschnitte des Schiebers 25 in korrespondierenden Nuten 36 des Saugkanalgehäuses 15 geführt werden.By depressing the handle 26 of the locking seat of the bolt 38 is released in the rear recess 29 and the slider 25 can be moved to the central recess 29 back. As a result, the driver 32 releases the boundary surface 34 and, by the force of the relaxing spring 11, the liquid application device 3 is brought into a middle working position according to FIG. 1 or FIGS. 6 and 7. There is now the driver 32 approximately centrally within the guide recess 33, whereby a resilient movement of the liquid application device 3 in the double arrow direction 10 is possible, which is limited by the boundary surfaces 34, 35 but. The displacement of the slider 25 can be performed out, for which purpose lateral, not shown guide portions of the slider 25 are guided in corresponding grooves 36 of the suction channel 15.

Weiter sind auch im Bogeninnern Führungen 37, 38 für eine schiebergesteuerte lineare Verschieblichkeit der Flüssigkeitsauftragsvorrichtung 3 vorgesehen. Die Führung 37 besteht aus einem Verlängerungsstück 39 der Flüssigkeitsauftragsvorrichtung 3, welches in einem Gleitteil 40 von rundem Querschnitt endet, das in einem Führungskanal 44 des Saugkanalgehäuses 15 linear verschiebbar ist. Solche Führungen 37 werden bevorzugt endseitig mit Bezug auf die Längserstreckung der Flüssigkeitsauftragsvorrichtung quer zur Arbeitsrichtung gemäß Pfeil 8 auch angeordnet. Hingegen wird mittig die Führung 38 bevorzugt vorgesehen, vgl. auch Fig. 3. Diese Führung 38 besteht aus einem Pilzkopf 41 mit Hut 42 von rundem Querschnitt, die in hinterschnittene Nuten 43 in der Flüssigkeitsauftragsvorrichtung 3 eingreifen, vgl. Fig. 7. Die flächige Erstreckung des Hutes 42, die Ausbildung der hinterschnittenen Nut 43, die Führungsausnehmung 33 sowie der Führungskanal 44 erfolgen in parallelen Ebenen. Infolge dessen ist bei einer bezüglich der Quererstreckung der Flüssigkeitsauftragsvorrichtung 3 zur Arbeitsrichtung 8 bei einer mittigen Anordnung der Führung 31 eine Schwenkbewegung um die Mittelachse 45 des Pilzkopfs 41 bei dessen rotationssymmetrischer Ausbildung auch möglich. Begrenzt wird eine solche Schwenkbewegung um die Mittelachse 45 durch den Anschlag der endseitig vorgesehenen Gleitteile 40 gegen die Deckfläche 46 des Führungskanals 44 oder andere geeignet ausgebildete Anschlagflächen.Further guides 37, 38 are provided for a slide-controlled linear displaceability of the liquid application device 3 in the sheet inside. The guide 37 consists of an extension piece 39 of the liquid application device 3, which ends in a sliding part 40 of round cross section, which is linearly displaceable in a guide channel 44 of the suction channel 15. Such guides 37 are preferably also arranged endwise with respect to the longitudinal extent of the liquid application device transversely to the working direction according to arrow 8. On the other hand, the guide 38 is preferably provided in the center, cf. Also, Fig. 3. This guide 38 consists of a mushroom head 41 with a hat 42 of round cross-section, which engage in undercut grooves 43 in the liquid application device 3, see. Fig. 7. The flat extent of the hat 42, the formation of the undercut groove 43, the guide recess 33 and the guide channel 44 take place in parallel planes. As a result, with respect to the transverse extent of the liquid application device 3 to the working direction 8 in a central arrangement of the guide 31, a pivoting movement about the central axis 45 of the mushroom head 41 in the rotationally symmetrical design also possible. Such a pivotal movement about the central axis 45 is limited by the stop of the sliding parts 40 provided on the end side against the cover surface 46 of the guide channel 44 or other suitably designed abutment surfaces.

Weiteres Verschieben des Schiebers 25 aus der Lage gemäß Fig. 6 in die in Fig. 9 gezeigte Lage bringt den Mitnehmer 32 in Anlage an die Begrenzungsfläche 35. Hierdurch wird die Flüssigkeitsauftragsvorrichtung 3 in eine der Saugmündung 21 vorstehende Lage gebracht. Ist dann der Riegel 28 in der vorderen Ausnehmung 29 verrastet, stützt sich die Flüssigkeitsauftragsvorrichtung 3 über den Schieber 25 gegen das Saugkanalgehäuse 15 ab. Ein weiteres Vorschieben der Flüssigkeitsauftragsvorrichtung 3 kann durch Anschläge der Führungen 37, 38 noch begrenzt werden. In dieser Lage ist nur ein Flüssigkeitsauftrag auf die reinigende Fläche 2 möglich.Further displacement of the slider 25 from the position shown in FIG. 6 in the position shown in Fig. 9 brings the driver 32 in abutment with the boundary surface 35. As a result, the liquid application device 3 is brought into a suction mouth 21 projecting position. Is then the latch 28 locked in the front recess 29, the liquid application device 3 is supported via the slide 25 against the suction channel housing 15. Further advancement of the liquid application device 3 can still be limited by stops of the guides 37, 38. In this situation, only a liquid application to the cleaning surface 2 is possible.

Anhand der Figuren 1 bis 3 wird speziell die Saugvorrichtung noch näher erläutert.The suction device will be explained in more detail with reference to FIGS. 1 to 3.

Die der zu reinigenden Fläche 2 zugewandte äußere Querschnittsfläche der Saugmündung 21 ist auf eine schlitzförmige Saugdüse 50 einer Breite weniger als 5 mm hier ca. 1,5 mm bis 2 mm gegenüber einem anschließenden Saugkanalabschnitt 51 verkleinert. In Absaugrichtung weist diese Querschnittsverengung eine Länge auf, die ihrer Breite etwa entspricht. Im Anschluß an die Saugdüse 50 wird das abgesaugte Flüssigkeits-Luftgemisch ein erstes mal umgelenkt, wozu in der Dichtlippe 31 eine die Strömungsrichtung umlenkende Ecke 57 ausgebildet ist. Es geht die Dichtlippe 31 im weiteren Verlauf des an die Saugdüse 50 anschließenden Saugkanalabschnitts 51 unmittelbar und stufenlos in eine die Saugmündung 21 begrenzende Innenwand 52 über. Die Strömung des abgesaugten Flüssigkeits-Luftgemischs wird im weiteren Verlauf des Saugkanalabschnittes 51 ein weiteres mal bei der Position 54 Z-fömig umgelenkt, bevor das Flüssigkeits-Luftgemisch in einer Absaugkammer 53 eintritt. Diese Umlenkung 54 durch schneidenförmig zueinanderstehende Flächen 55, 56 verhindert insbesondere auch in Verbindung mit der Ausbildung der Saugdüse 50 ein Tropfen aus der Saugmündung 21, wenn das Sauggerät abgeschaltet wird.The outer cross-sectional area of the suction mouth 21 facing the surface 2 to be cleaned is reduced to a slot-shaped suction nozzle 50 having a width of less than 5 mm, approximately 1.5 mm to 2 mm in relation to a subsequent suction channel section 51. In the suction direction, this cross-sectional constriction has a length which corresponds approximately to its width. Subsequent to the suction nozzle 50, the aspirated liquid-air mixture is deflected a first time, for which purpose in the sealing lip 31, a corner 57 which deflects the direction of flow is formed. In the further course of the suction channel section 51 adjoining the suction nozzle 50, the sealing lip 31 passes directly and steplessly into an inner wall 52 delimiting the suction opening 21. The flow of the aspirated liquid-air mixture is in the further course of the Saugkanalabschnittes 51 once again deflected Z-fömig at the position 54 before the liquid-air mixture enters a suction chamber 53. This deflection 54 by surfaces 55, 56 which are in the shape of a cutting edge, in particular prevents, in conjunction with the formation of the suction nozzle 50, a drop from the suction orifice 21 when the suction device is switched off.

In ihrer Längserstreckung und damit quer zur Arbeitsrichtung 8 ist die schlitzförmige Saugmündung in einzelne Saugabschnitte 60 unterteilt, vgl. auch Fig. 3 und die unterschiedliche Darstellung in den Fig. 1 und 3, welche quer zur Arbeitsrichtung 8 geringfügig im Bereich der Saugmündung 21 auch versetz sind. Der Unterteilung in einzelne Saugabschnitte 60 dienen Rippen 61 unterschiedlicher Höhe und unterschiedlicher Anstellwinkel. Der Anstellwinkel gegenüber der Vertikalen gemäß Fig. 2 nimmt mit der Lage der Rippen 61 nach außen, d.h. hin zu den seitlichen Randbereichen 62 der Saugmündung 21, zu. Darüber hinaus wird die Länge der Saugabschnitte 60 quer zur Arbeitsrichtung 8 nach außen hin vergrößert. Durch diese Maßnahmen wird eine gleichmäßige Absaugung über die gesamte Erstreckung der Saugmündung 21 sichergestellt. Die Rippen 61 fassen damit auch eine Vielzahl von Saugkanalabschnitten 51 zwischen sich ein, welche in der gemeinsamen Absaugkammer 53 münden. An der gemeinsamen Absaugkammer 53 sind mehrere, hier zwei Saugrohrverzweigungen 63, 64 angeschlossen, die hier lediglich idealisiert durch die Zusammenfassung von Bahnlinien 65 der abgesaugten Flüssigkeit-Luftgemischströmung dargestellt sind. Weiter in Absaugrichtung gemäß Pfeil 66 werden die durch die Bahnlinien 65 im wesentlichen dargestellten zwei Saugrohrverzweigungen 63, 64 in einem gemeinsamen Saugkanalquerschnitt zusammengefaßt, in Fig. 3 durch den Knoten 67 dargestellt.In its longitudinal extension and thus transversely to the working direction 8, the slot-shaped suction mouth is divided into individual suction sections 60, cf. Also Fig. 3 and the different representation in Figs. 1 and 3, which are transversely to the working direction 8 slightly offset in the region of the suction port 21. The subdivision into individual suction sections 60 serve ribs 61 of different height and different angle of attack. The angle of attack with respect to the vertical of FIG. 2 increases with the position of the ribs 61 to the outside, i. towards the lateral edge regions 62 of the suction mouth 21, too. In addition, the length of the suction portions 60 is increased transversely to the working direction 8 to the outside. Through these measures, a uniform suction over the entire extension of the suction orifice 21 is ensured. The ribs 61 thus also encompass a multiplicity of suction channel sections 51 which open in the common suction chamber 53. At the common suction 53 a plurality of, here two Saugrohrverzweigungen 63, 64 are connected, which are shown here only idealized by the combination of lines 65 of the extracted liquid-air mixture flow. Next in the suction direction as indicated by arrow 66, the two Saugrohrverzweigungen 63, 64 substantially represented by the web lines 65 are summarized in a common Saugkanalquerschnitt, shown in Fig. 3 by the node 67.

Da bei dem Ausführungsbeispiel der Schieber 25 bezüglich der schlitzförmigen Saugkanalmündung 21 das Saugkanalgehäuse 15 etwa mittig durchsetzt, wird der Schieber 25 und hier die Führung 38 zwischen den Saugrohrverzweigungen 63, 64 eingefaßt. Die Darstellung gemäß Fig. 3, in welcher die Flüssigkeitsauftragsvorrichtung nicht dargestellt ist, zeigt den Pilzkopf 41 der Führung 38 auf der Achse 68 liegend. Auch der saugkanalgehäusefeste Zapfen 13 auf der Halteplatte 14 für die Feder 11 ist in seiner zentralen Anordnung bezüglich der Achse 68 erkennbar. Es liegt der Zapfen 13 weiter zwischen den Nuten 36 für die seitliche Führung des Schiebers 25.Since in the embodiment of the slider 25 with respect to the slot-shaped Saugkanalmündung 21, the Saugkanalgehäuse 15 passes approximately centrally, the slider 25 and here the guide 38 between the Saugrohrverzweigungen 63, 64 bordered. The illustration of FIG. 3, in which the liquid application device is not is shown, the mushroom head 41 of the guide 38 lying on the axis 68. Also, the suction channel housing fixed pin 13 on the support plate 14 for the spring 11 can be seen in its central arrangement with respect to the axis 68. It is the pin 13 further between the grooves 36 for the lateral guidance of the slider 25th
