Description

Die Erfindung betrifft eine Sprühextraktlonsdüse mit einem Saugkanal, welcher in einem Saugmund endet und mit einer Sprühdüse sowie mit einem Adapter zur Bearbeitung von Oberflächen, die unterschiedliche Beschaffenheiten aufweisen.The invention relates to a spray extractor nozzle with a suction channel which ends in a suction mouth and with a spray nozzle and with an adapter for processing surfaces having different textures.

Sprühextraktionsdüsen sind seit langem, z.B. durch die US 3,616,482 bekannt. Sie dienen dazu auf einer Oberfläche aufgebrachte Flüssigkeiten über den Saugmund aufzunehmen und durch den Saugkanal und ggf. Saugleitungen einem Sauger zuzuführen. Der Saugmund weist in der Regel zwei harte, starre Lippen oder zwei mit Borsten versehene Lippen auf zwischen denen die Flüssigkeit eingesaugt werden kann. Der Saugmund ist mit seinen beiden starren Lippen in der Regel für Teppichbeläge gedacht. Dabei ist stets darauf zu achten, dass die beiden Lippen des Saugmundes möglichst exakt auf dem Teppich aufliegen um eine möglichst optimale Saugwirkung zu erzeugen.Spray extraction nozzles have long been, for example by the US 3,616,482 known. They serve to absorb liquids applied to a surface via the suction mouth and to feed them through the suction channel and possibly suction lines to a suction device. The suction mouth usually has two hard, rigid lips or two bristled lips between which the liquid can be sucked. The suction mouth is usually intended for carpeting with its two rigid lips. It is always important to ensure that the two lips of the suction mouth lie as exactly as possible on the carpet to create the best possible suction.

Werden die Lippen z.B. durch eine Schiefstellung des Saugmundes der Sprühextraktionsdüse nicht beide auf den Teppich gepresst, lässt die Saugwirkung erheblich nach und die Restfeuchte nimmt stark zu.If the lips are e.g. due to a misalignment of the suction mouth of the spray extraction nozzle, both are not pressed onto the carpet, the suction effect decreases considerably and the residual moisture increases considerably.

Sollten andere Oberflächen z.B. Hartflächen von aufgebrachten Flüssigkeiten befreit werden, kann ein Saugmund mit den an den Lippen angeordneten Borsten Verwendung findeIf other surfaces, eg hard surfaces, are to be freed from applied liquids, a suction mouth with the bristles arranged on the lips can be used

Es lassen sich auf die bekannten Sprühextraktionsdüsen auch schon Adapter aufsetzen, die mindestens eine Gummilippe aufweisen, mittels derer Flüssigkeiten leichter von Hartflächen zu entfernen sind. Nachteil ist dabei, dass diese Adapter umständlich auf die Sprühextraktionsdüsen aufzusetzen sind, in der Regel, wenn sie benötigt werden, nicht zur Stelle sind und gesucht werden müssen, und auch beim Entfernen von Hand, diese leicht beschmutzen.Adapters which have at least one rubber lip, by means of which liquids can be more easily removed from hard surfaces, can also be placed on the known spray extraction nozzles. Disadvantage is that these adapters are cumbersome to put on the spray extraction nozzles, usually, when they are needed, are not in place and must be searched, and even when removing by hand, this dirty easily.

Der Erfindung liegt die Aufgabe zugrunde, Adapter für Sprühextraktionsdüsen für ein unkompliziertes Wechseln so vorzusehen, dass sie nicht zwingend von Hand in und außer Wirkstellung gebracht werden müssen, nicht so leicht verloren gehen und bei deren Bedienung eine möglichst geringe Restfeuchte auf den Oberflächen verbleibt.The invention has for its object to provide adapter for spray extraction nozzles for easy changing so that they do not necessarily have to be brought by hand in and out of operative position, not so easily lost and the operation of the lowest possible residual moisture remains on the surfaces.

Dazu wird vorgeschlagen, dass der Adapter über eine Schwenkachse mit der Sprühextraktionsdüse verbunden ist und dass der Adapter aus einer vom Saugmund entfernten Ruhestellung vor den Saugmund der Sprühextraktionsdüse in eine Arbeitsstellung schwenkbar ist.For this purpose, it is proposed that the adapter is connected via a pivot axis with the spray extraction nozzle and that the adapter is pivotable from a suction position remote from the suction mouth of the spray extraction nozzle in a working position.

Durch das Befestigen des Adapters an der Sprühextraktionsdüse wird gewährleistet, dass der Adapter nicht verloren gehen kann. Die Schwenkbewegung ist z.B. mittels eines Fußes ausführbar, so dass die händische Betätigung mit der entsprechenden Verschmutzung der Hände entfällt.Attaching the adapter to the spray extraction nozzle ensures that the adapter can not be lost. The pivoting movement is e.g. Executable by means of a foot, so that the manual operation is eliminated with the corresponding contamination of the hands.

Von Vorteil ist, dass der Adapter in der Arbeitsstellung lösbar arretierbar ist. Damit der Adapter in der Arbeitsstellung auch bei größeren Drücken und Querbelastungen des Adapters in der Arbeitsstellung verbleibt, ist einerseits ein Anschlag vorgesehen gegen den der Adapter in die Arbeitsstellung schwenkbar ist und eine Arretiervorrichtung, mit welcher der Adapter in der Arbeitsstellung so arretiert wird, dass er bei jeder möglichen Bedienungsphase am Anschlag verbleibt. Bei Bedarf kann die Arretierung gelöst, und der Adapter aus der Arbeitsstellung heraus geschwenkt werden.It is advantageous that the adapter is releasably lockable in the working position. Thus, the adapter remains in the working position even with larger pressures and transverse loads of the adapter in the working position, on the one hand, a stop provided against the adapter in the working position is pivotal and a locking device with which the adapter is locked in the working position so that he remains at the stop at every possible operating phase. If necessary the lock can be released, and the adapter can be pivoted out of the working position.

Wird der Adapter in der Ruhestellung lösbar arretiert, so ist gewährleistet, dass der Adapter nicht ungewollt aus der Ruhrstellung in die Arbeitsstellung verschwenken kann.If the adapter is releasably locked in the rest position, it is ensured that the adapter can not unintentionally pivot from the Ruhr position into the working position.

Bemerkenswert ist, dass der Adapter in seiner Ruhestellung eine Auflagefläche für die Sprühextraktionsdüse auf der zu bearbeitenden Oberfläche darstellt, und dem Saugmund eine optimale Stellung zur zu bearbeitenden Oberfläche verleiht. Die Ruhestellung des Adapters ist so ausgelegt, dass die Sprühextraktionsdüse großflächig auf dem Adapter aufliegt und dabei beide Düsenlippen des Düsenmundes optimal zur Oberfläche positioniert sind.It is noteworthy that the adapter in its rest position, a support surface for the spray extraction nozzle on the surface to be machined, and gives the suction mouth an optimal position to be machined surface. The idle position of the adapter is designed so that the spray extraction nozzle rests on a large area on the adapter while both nozzle lips of the nozzle mouth are optimally positioned to the surface.

Es hat sich bewährt, dass die Schwenkachse zweiteilig ausgebildet und mindestens ein Teil der Schwenkachse lageveränderbar ist, wobei die Lageveränderung der Schwenkachse über eine Betätigungsvorrichtung erfolgt und wobei das Maß der Lageveränderung der Schwenkachse mindestens so eingestellt ist, dass die Schwenkachse aus der diese aufnehmenden Bohrung des Adapters zurückziehbar ist.It has been proven that the pivot axis is formed in two parts and at least a portion of the pivot axis is variable position, wherein the change in position of the pivot axis via an actuator and wherein the degree of change in position of the pivot axis is set at least so that the pivot axis of the receiving bore of this Adapter is retractable.

Dadurch lässt sich der Adapter gegen neue Adapter aber auch gegen andere Adapter austauschen, so dass eine optimale Anpassung an sämtliche zu bearbeitenden Oberflächen möglich ist.As a result, the adapter can be exchanged for new adapters but also for other adapters, so that an optimal adaptation to all surfaces to be machined is possible.

Von besonderem Vorteil ist, dass die Sprühextraktionsdüse eine im Wesentlichen dreieckige Form mit seitlichen Ausladungen aufweist.Of particular advantage is that the spray extraction nozzle has a substantially triangular shape with lateral projections.

Die seitlichen Ausladungen sind so angeordnet, dass mit der Sprühextraktionsdüse auch bereichsweise unter Überstände, wie sie z.B. durch Schränke entstehen gearbeitet werden kann, so dass auch im Bereich von Schränken keine sichtbaren, unbearbeiteten Ränder entstehen können.The lateral projections are arranged so that with the spray extraction nozzle also partially under supernatants, as e.g. can be worked through cabinets, so that even in the range of cabinets no visible, unprocessed edges can arise.

Nachahmenswert ist, dass der Saugkanal über seine gesamte Länge den gleichen Querschnitt wie die Saugmund aufweist. Dadurch ist gewährleistet, dass der Flüssigkeitsabtransport im Inneren optimal erfolgt, im wesentlichen laminare Strömungen entstehen und keine Geschwindigkeitsunterschiede aufkommen. Hinzu kommt, dass ein Zurückfließen bereits aufgesaugter Flüssigkeit beim Ausschalten des Sauggerätes dadurch vermieden wird.It is worth noting that the suction channel has the same cross-section as the suction mouth over its entire length. This ensures that the liquid removal takes place optimally in the interior, essentially laminar flows arise and no speed differences arise. In addition, a backflow already sucked liquid when turning off the suction device is thereby avoided.

Weitere Vorteile ergeben sich, wenn den Sprühdüsen Leitkanäle zugeordnet sind.Further advantages arise when the spray nozzles Leitleitäle are assigned.

Die Leitkanäle bewirken, dass das die Sprühdüse verlassende Reinigungsmittel nicht über den Rand der Sprühextraktionsdüse hinaus z.B. an Wände oder Möbel gelangen kann, sondern durch die Leitkanäle exakt auf die zu bearbeitenden Flächen gesprüht wird.The guide channels cause the detergent leaving the spray nozzle to not extend beyond the edge of the spray extraction nozzle, e.g. can get to walls or furniture, but is sprayed by the Leitkanäle exactly on the surfaces to be processed.

Figur 1 zeigt eine Sprühextraktionsdüse 1 mit einem Saugkanal 2 sowie einem Saugmund 3. Über eine Schwenkachse 4, 4' ist ein Adapter 5 mit der Sprühextraktionsdüse 1 verbunden. Über eine Betätigungsvorrichtung 6 lässt sich die Schwenkachse 4 in ihrer Längsrichtung verschieben, so dass beim Eindrücken der Betätigungsvorrichtung 6 die Schwenkachse 4 aus der Bohrung 7 des Adapters 5 herausbewegt wird. Damit wird der Adapter 5 an einer seiner beiden Aufhängungspunkte frei und kann entfernt und gegen einen neuen bzw. einen anderen Adapter ausgetauscht werden. FIG. 1 shows a spray extraction nozzle 1 with a suction channel 2 and a suction mouth 3. About a pivot axis 4, 4 ', an adapter 5 is connected to the spray extraction nozzle 1. Via an actuating device 6, the pivot axis 4 can be moved in its longitudinal direction, so that the pivot axis 4 is moved out of the bore 7 of the adapter 5 when pressing the actuator 6. Thus, the adapter 5 at one of its two suspension points free and can be removed and replaced with a new or another adapter.

Die Fig. 1 lässt weiterhin eine Arretiervorrichtung 8 erkennen, welche gegen die Kraft von nicht dargestellten Federn nach unten bewegt werden kann. Am unteren Ende der Arretiervorrichtung 8 sind Haken 9 in Form von Widerhaken angeordnet, welche in entsprechende Gegenstücke des Adapters 5 einzugreifen vermögen. Durch die Widerhakenwirkung wird gewährleistet, dass bei einer Querbelastung oder Biegung des Adapters 5 dieser sich stets fester mit der Arretiervorrichtung 8 verkrallt, und so ein ungewolltes Wegklappen des Adapters 8 ausgeschlossen wird.The Fig. 1 can also recognize a locking device 8, which can be moved against the force of springs, not shown, down. At the lower end of the locking device 8 hooks 9 are arranged in the form of barbs, which are able to intervene in corresponding counterparts of the adapter 5. The barb effect ensures that, in the event of a transverse load or bending of the adapter 5, it always claws more firmly with the locking device 8, thus precluding unwanted folding away of the adapter 8.

In der Fig. 2 ist der Adapter 5 vor den Saugmund 3 geschwenkt. die Arretiervorrichtung 8 hält den Adapter 5 in der so dargestellten Arbeitsstellung.In the Fig. 2 the adapter 5 is pivoted in front of the suction mouth 3. the locking device 8 holds the adapter 5 in the working position shown.

Fig. 3 zeigt die Sprühextraktionsdüse 1 in der Hinteransicht. Hier ist der Saugmund 3 sowie der Adapter 5 zu erkennen, welcher mittels der Schwenkachse 4 schwenkbar an der Sprühextraktionsdüse 1 befestigt ist. Weiterhin sind Haken 10, 10' zu erkennen, welche den Adapter 5 in der Ruhestellung halten. Bei den Haken 10, 10' handelt es sich um Schnapphaken, die durch einfaches Betätigen des Adapters 5 z.B. durch einen Fuß federnd auseinander schnappen und den Adapter 5 aus der Ruhestellung freigeben. Fig. 3 shows the spray extraction nozzle 1 in the rear view. Here, the suction mouth 3 and the adapter 5 can be seen, which is fastened by means of the pivot axis 4 pivotally mounted on the spray extraction nozzle 1. Furthermore, hooks 10, 10 'can be seen, which hold the adapter 5 in the rest position. The hooks 10, 10 'are snap hooks, which snapping apart by simply pressing the adapter 5, for example by a foot and release the adapter 5 from the rest position.

Der Adapter 5 weist anders als der Saugmund 3, der zwei feste Sauglippen 11, 11' besitzt, mindestens eine Borstenleiste 12 und mindestens eine Gummilippe 13 auf, mittels derer Flüssigkeiten optimal von Hartflächen zusammen geschoben und dann aufgesaugt werden können.Unlike the suction mouth 3, which has two fixed suction lips 11, 11 ', the adapter 5 has at least one bristle strip 12 and at least one rubber lip 13, by means of which liquids can be optimally pushed together by hard surfaces and then sucked up.

Der Fig. 3 ist weiterhin ein Arretierungsmaul 14 zu entnehmen, in welches eine Sprühdüse eingesetzt werden kann. Die Sprühdüse wird dabei zwischen Leitelementen 15, 16 so nach unten ausgerichtet, dass der Sprühstrahl nicht seitlich über die Leitelemente 15, 16 hinaus versprüht werden kann. Dadurch werden weder Wände noch Möbel benässt, wenn mit der Sprühextraktionsdüse in deren Nähe gearbeitet wird.Of the Fig. 3 Furthermore, it can be seen a locking jaw 14, in which a spray nozzle can be used. The spray nozzle is between guide elements 15, 16 aligned so down that the spray can not be sprayed laterally beyond the guide elements 15, 16 addition. As a result, neither walls nor furniture are wetted when working with the spray extraction nozzle in their vicinity.

Weiterhin ist eine Auflagefläche 17 des Adapters 5 zu erkennen, welche bei Adapter 5 in Ruhestellung in gleicher Ebene wie die Lippen 11, 11' liegt. Bei auf der zu bearbeitenden Oberfläche aufliegender Auflage 17 bewirkt diese, dass sich die Lippen 11, 11' in optimaler Saugstellung befinden, wodurch die Restfeuchte minimiert werden kann.Furthermore, a support surface 17 of the adapter 5 can be seen, which in the case of adapter 5 is at rest in the same plane as the lips 11, 11 '. When resting on the surface to be processed edition 17 causes this, that the lips 11, 11 'are in optimal suction position, whereby the residual moisture can be minimized.

Die Fig. 4 zeigt einen Schnitt durch die Sprühextraktionsdüse 1, wobei der Saugkanal 2 und der Saugmund 3 mit seinen Lippen 11, 11' zu erkennen sind. Die Lippe 11' dient als Anschlag für den Adapter 5. Bei einer ziehenden Bewegung der Sprühextraktionsdüse 1 wird der Adapter 5 gegen die als Anschlag dienende Lippe 11' gezogen. Weiterhin sind die Borstenleiste 12 und die Gummilippe 13 des Adapters 5 zu erkennen sowie die Arretiervorrichtung 8, die mit ihren Haken 9 in einen entsprechenden Gegenhaken 9' des Adapters 5 eingreift. Bei einer schiebenden Bewegung der Sprühextraktionsdüse 1 ziehen sich die Haken 9, 9' immer fester ineinander, so dass der Adapter 5 nicht verschwenkt werden kann. Erst durch ein verschieben z.B. durch Fußbetätigung der Arretiervorrichtung 8 wird bewirkt, dass die Haken 9 aus dem Haken 9' heraus gleitet.The Fig. 4 shows a section through the spray extraction nozzle 1, wherein the suction channel 2 and the suction mouth 3 can be seen with its lips 11, 11 '. The lip 11 'serves as a stop for the adapter 5. In a pulling movement of the spray extraction nozzle 1, the adapter 5 is pulled against the serving as a stop lip 11'. Furthermore, the bristle strip 12 and the rubber lip 13 of the adapter 5 can be seen and the locking device 8, which engages with its hook 9 in a corresponding counter hook 9 'of the adapter 5. In a sliding movement of the spray extraction nozzle 1, the hooks 9, 9 'tighten more and more firmly, so that the adapter 5 can not be pivoted. Only by a move, for example, by foot actuation of the locking device 8 causes the hooks 9 'from the hook 9' slides out.

In allen Figuren ist die im Wesentlichen dreieckige Form der Sprühextraktionsdüse 1 zu erkennen, welche jedoch im unteren Bereich Ausladungen 18, 18' aufweisen, die so angeordnet sind, dass mit der Sprühextraktionsdüse 1 z.B. so weit unter Schränken gearbeitet werden kann, dass keine unbearbeiteten Ränder zu erkennen sind.In all figures, the substantially triangular shape of the spray extraction nozzle 1 can be seen, which, however, in the lower region projections 18, 18 ', which are arranged so that with the spray extraction nozzle 1, for example, can work under cabinets so far that no raw edges can be seen.
