Description

Die Erfindung betrifft ein Reinigungsgerät zum Trocken- oder Naßsaugen und/oder zur Sprühextraktionsreinigung mit einem Saugöffnungen aufweisenden Saugkopf, der mit einer Saugleitung in Verbindung steht, und mit einer am Saugkopf in einer Sprühdüse endenden Sprühleitung für eine Reinigungsflüssigkeit.The invention relates to a cleaning device for dry or wet suction and / or for spray extraction cleaning with a suction head having suction openings, which is connected to a suction line, and with a spray line ending in a spray nozzle for a cleaning liquid at the suction head.

Geräte, die wahlweise als Naß- oder Trockensauger oder als Sprühextraktionsgeräte (WO-A-79 00 755) verwendet werden, müssen normalerweise mit unterschiedlichen Arbeitsköpfen ausgestattet werden. Beim Übergang von einer auf die andere Reinigungsart ist daher ein komplizierter Wechsel der jeweiligen Saugköpfe notwendig. Ein solcher Wechsel ist zwar bei industriell eingesetzten Reinigungsgeräten zumutbar, nicht dagegen bei Haushaltsgeräten.Devices that are used either as wet or dry vacuum cleaners or as spray extraction devices (WO-A-79 00 755) usually have to be equipped with different working heads. When changing from one type of cleaning to another, a complicated change of the respective suction heads is necessary. Such a change is reasonable for industrial cleaning devices, but not for household appliances.

Es ist Aufgabe der Erfindung, ein wahlweise als Trocken- oder Naßsauger oder als Sprühextraktionsreinigungsgerät verwendbares Gerät derart weiterzubilden, daß ein und derselbe Saugkopf ohne wesentliche Umrüstungsarbeiten für alle Reinigungsvorgänge verwendet werden kann.It is an object of the invention to develop a device which can be used either as a dry or wet vacuum cleaner or as a spray extraction cleaning device in such a way that one and the same suction head can be used for all cleaning processes without substantial conversion work.

Diese Aufgabe wird bei einem Reinigungsgerät der im einleitenden Teil des Anspruchs 1 angegebenen Art (DE-A-1 403 638) erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 genannten Merkmale gelöst.This object is achieved in a cleaning device of the type specified in the introductory part of claim 1 (DE-A-1 403 638) according to the invention by the features mentioned in the characterizing part of claim 1.

Es ist damit möglich, jeweils eine der beiden Saugöffnungen für die verschiedenen Reinigungsvorgänge zu verwenden. Die Saugöffnung an der Unterseite des Saugkopfes wird in herkömmlicher Weise zum Naß- und Trockensaugen eingesetzt, während dieses Vorganges ist die stirnseitige Saugöffnung verschlossen.It is therefore possible to use one of the two suction openings for the different cleaning processes. The suction opening on the underside of the suction head is used in a conventional manner for wet and dry suction, during this process the front suction opening is closed.

Für den Sprühextraktionsbetrieb wird dagegen die stirnseitige Öffnung geöffnet, während die Saugöffnung an der Unterseite verschlossen wird. Der Saugkopf wird dann - beispielsweise bei entsprechender Neigung des Saugkopfes gegenüber der Saugleitung durch Drehung derselben um 180° - so positioniert, daß nunmehr die Stirnseite gegen die zu reinigenden Fläche gerichtet ist, so daß die stirnseitige Saugöffnung wirksam wird. Beide Saugöffnungen können für die jeweilige Aufgabe speziell ausgerüstet sein, beispielsweise wird die Saugöffnung an der Unterseite mit Bürsten oder Dichtlippen versehen, während die Saugöffnung an der Stirnseite, die zum Sprühextraktionsreinigen verwendet wird, harte Ränder aufweist, die kräftig gegen die zu reinigende Fläche gedrückt werden können und den Reinigungsvorgang selbst unterstützen können.For spray extraction operation, on the other hand, the front opening is opened while the suction opening on the underside is closed. The suction head is then - for example with a corresponding inclination of the suction head relative to the suction line by rotating the same by 180 ° - positioned so that the end face is now directed against the surface to be cleaned, so that the front suction opening becomes effective. Both suction openings can be specially equipped for the respective task, for example the suction opening on the underside is provided with brushes or sealing lips, while the suction opening on the front side, which is used for spray extraction cleaning, has hard edges that are pressed firmly against the surface to be cleaned and can support the cleaning process itself.

Der Saugkopf ist an der Saugleitung um eine parallel zu der zu reinigenden Fläche verlaufende Achse verschwenkbar und in einer bestimmten Winkelstellung fixierbar ist. Es ist dann vorteilhaft, beim Trocken- und Naßsaugbetrieb ohne Sprühextraktion den Saugkopf an der Saugleitung frei verschwenkbar zu belassen, also nicht in einer bestimmten Winkelstellung zu fixieren, so daß sich der Saugkopf in an sich bekannter Weise der zu reinigenden Fläche anpaßt, wobei der Benutzer die Saugleitung mit unterschiedlicher Neigung führen kann.The suction head can be pivoted on the suction line about an axis running parallel to the surface to be cleaned and can be fixed in a certain angular position. It is then advantageous to leave the suction head freely pivotable on the suction line during dry and wet suction operation without spray extraction, i.e. not to fix it in a certain angular position, so that the suction head adapts to the surface to be cleaned in a manner known per se, the user the suction line can lead with different inclinations.

Zum Sprühextrahieren ist es jedoch vorteilhaft, den Saugkopf gegenüber der Saugleitung in seiner Winkelstellung zu fixieren, so daß der Benutzer den Saugkopf über die Saugleitung kräftig gegen die zu reinigende Fläche drücken kann, wobei gleichzeitig eine ziehende Bewegung auf den Saugkopf ausgeübt wird.For spray extraction, however, it is advantageous to fix the suction head relative to the suction line in its angular position, so that the user can press the suction head vigorously against the surface to be cleaned via the suction line, a pulling movement being simultaneously exerted on the suction head.

Es ist besonders vorteilhaft, wenn die Stirnseite gegenüber der Unterseite in Verschieberichtung des Saugkopfes gesehen kürzer ist. Dadurch steht der Saugkopf beim Sprühextrahieren « hochkant •, so daß sich in Verschieberichtung des Saugkopfes gesehen zu beiden Seiten der Saugöffnung nur noch die schmalen, die Öffnung begrenzenden Kanten befinden. Diese konnen dadurch besonders wirksam in die zu reinigende Fläche eingreifen, beispielsweise in einen Teppichboden. Außerdem bildet der hochkant stehende, wandförmige Saugkopf nach vorne eine Begrenzung für den gegen den Teppichboden gerichteten Sprühstrahl, so daß keine Flüssigkeit in den bereits vom Saugkopf bearbeiteten Bereich gelangen kann.It is particularly advantageous if the end face is shorter compared to the underside in the direction of displacement of the suction head. As a result, the suction head stands upright during spray extraction, so that, seen in the direction of displacement of the suction head, there are only the narrow edges delimiting the opening on both sides of the suction opening. As a result, these can intervene particularly effectively in the surface to be cleaned, for example in a carpet. In addition, the upright, wall-shaped suction head forms a front boundary for the spray jet directed against the carpet, so that no liquid can get into the area already processed by the suction head.

Zum selektiven Verschließen der beiden Saugöffnungen kann ein im Inneren des Saugkopfes verdrehbar gelagertes Verschlußelement vorgesehen sein, welches von außen entweder in die Verbindung der unterseitigen Saugöffnung mit der Saugleitung oder in die Verbindung der stirnseitigen Saugöffnung mit der Saugleitung verdrehbar ist. Damit wird durch einfaches Verdrehen eines solchen Verschlußelementes eine Umstellung von einer Saugöffnung auf die andere möglich.To selectively close the two suction openings, a closure element rotatably mounted in the interior of the suction head can be provided, which can be rotated from the outside either into the connection of the suction opening on the underside with the suction line or into the connection of the suction opening on the front side with the suction line. A change from one suction opening to the other is thus possible by simply rotating such a closure element.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß die Sprühextraktionsdüse und/oder ein in die Sprühleitung eingeschaltetes Schließventil lösbar an der Saugleitung befestigt sihd. Es ist dann möglich, beim Naß- und Trockensaugbetrieb die Sprühleitung mit Sprühdüse und Schließventil von der Saugleitung zu entfernen und beispielsweise in dem Reinigungsgerät selbst aufzubewahren. Nur für den Zweck der Sprühextraktion werden diese Teile an der Sprühleitung befestigt, wobei diese Befestigung vorzugsweise mit federnden Klipsen erfolgt, die auf die Saugleitung aufgesteckt werden.In a preferred embodiment it is provided that the spray extraction nozzle and / or a closing valve switched into the spray line are detachably attached to the suction line. It is then possible to remove the spray line with spray nozzle and closing valve from the suction line during wet and dry suction operation and, for example, to store it in the cleaning device itself. These parts are attached to the spray line only for the purpose of spray extraction, this attachment preferably being carried out with resilient clips which are plugged onto the suction line.

Der in der Zeichnung dargestellte Saugkopf ist Teil eines in der Zeichnung nicht wiedergegebenen Reinigungsgerätes, welches mittels eines Saugaggregates eine Schmutzabsaugung und mittels einer Förderpumpe bei Bedarf ein flüssiges Reinigungsmittel zur Verfügung stellt.The suction head shown in the drawing is part of a cleaning device which is not shown in the drawing and which provides a dirt suction by means of a suction unit and, if necessary, a liquid cleaning agent by means of a feed pump.

Die Saugseite des Saugaggregates wird unter Zwischenschaltung eines Schmutzsammelbehälters über einen flexiblen Saugschlauch 2 mit einer rohrförmigen, starren Saugleitung 1 verbunden, der in einen Saugkopf 3 einmündet. Dieser Saugkopf hat die Form eines flachen Quaders mit einer ebenen Oberseite 4, einer Unterseite 5, zwei Seitenwänden 6 und 7, einer im Querschnitt kreisbogenförmig gebogenen Rückwand 8 und einer Stirnwand 9.The suction side of the suction unit is connected, with the interposition of a dirt collecting container, via a flexible suction hose 2 to a tubular, rigid suction line 1, which opens into a suction head 3. This suction head has the shape of a flat cuboid with a flat upper side 4, a lower side 5, two side walls 6 and 7, a rear wall 8 curved in the shape of a circular arc and an end wall 9.

Die Gesamtlänge des Saugkopfes von der Stirnwand 9 zur Rückwand 8 ist wesentlich größer als die Höhe des Saugkopfes zwischen Oberseite und Unterseite, beispielsweise viermal größer.The total length of the suction head from the front wall 9 to the rear wall 8 is substantially greater than the height of the suction head between the top and bottom, for example four times larger.

Die Saugleitung 1 mündet in den rückwärtigen Teil des Saugkopfes 3 ein, und in diesem Bereich sind Saugkopf 3 und Saugleitung 1 um eine parallel zur Rückwand 8 verlaufende Drehachse verschwenkbar miteinander verbunden. Mittels eines seitlich aus dem Gehäuse hervorstehenden Drehgriffes 10 ist die relative Winkellage des Saugkopfes gegenüber der Saugleitung 1 feststellbar. Dies kann mittels einer an sich bekannten Klemmvorrichtung erfolgen, es ist auch möglich, daß eine solche Feststellung in verschiedenen Stufen durch Eingreifen von Rastelementen in Rastausnehmungen erfolgt. Hier sind dem Fachmann verschiedene äquivalente Möglichkeiten an die Hand gegeben. Der Drehgriff 10 kann aber auch in einer Stellung verbleiben, in der Saugleitung 1 und Saugkopf 3 frei gegeneinander verschwenkbar sind.The suction line 1 opens into the rear part of the suction head 3, and in this area the suction head 3 and suction line 1 are pivotally connected to one another about an axis of rotation running parallel to the rear wall 8. The relative angular position of the suction head relative to the suction line 1 can be determined by means of a rotary handle 10 protruding laterally from the housing. This can be done by means of a clamping device known per se, it is also possible for such a determination to be carried out in different stages by the engagement of locking elements in locking recesses. Various equivalent options are available to the person skilled in the art here. The twist grip 10 can also remain in a position in which the suction line 1 and suction head 3 can be freely pivoted relative to one another.

Der Saugkopf 3 weist in seiner Unterseite 5 eine schlitzförmige, sich quer über die gesamte Breite des Saugkopfes 3 erstreckende Saugöffnung 11 auf, die an beiden Enden von Kufen 12 begrenzt ist, die nach unten über die Unterseite 5 des Saugkopfes 3 hervorstehen und somit die Saugöffnung 11 im Abstand von einer zu reinigenden Fläche 13 halten, auf der der Saugkopf mit der Unterseite nach unten aufgelegt ist (Figur 2).The suction head 3 has in its underside 5 a slit-shaped suction opening 11 which extends across the entire width of the suction head 3 and is delimited at both ends by runners 12 which project downwards over the underside 5 of the suction head 3 and thus the suction opening 11 keep at a distance from a surface 13 to be cleaned, on which the suction head is placed with the underside downward (FIG. 2).

An der Vorderseite verläuft parallel zu der schlitzförmigen Saugöffnung 11 eine flexible Dichtlippe 14, an der Rückseite eine Borstenleiste 15.A flexible sealing lip 14 runs parallel to the slot-shaped suction opening 11 on the front, and a bristle strip 15 on the rear.

In der Stirnwand 9, zu der die Oberseite 4 und die Unterseite 5 des Saugkopfes 3 konvergierend zusamnenlaufen, ist eine weitere, schlitzförmige, sich über die gesamte Breite des Saugkopfes erstreckende Saugöffnung 16 angeordnet, die im wesentlichen die gesamte Fläche der Stirnwand 9 einnimmt und nur von einem schmalen Rand 17 umgeben wird, der von dem Saugkopf selbst gebildet wird (Figur 3).In the end wall 9, to which the upper side 4 and the lower side 5 of the suction head 3 converge, there is a further, slit-shaped suction opening 16 which extends over the entire width of the suction head and occupies essentially the entire area of the end wall 9 and only is surrounded by a narrow edge 17 which is formed by the suction head itself (FIG. 3).

Der hohle Innenraum 18 des Saugkopfes steht einerseits über eine geeignete Abdichtung mit der Saugleitung 1 in Verbindung, andererseits mit den beiden Saugöffnungen 11 und 16 des Saugkopfes. Um eine parallel zu den beiden schlitzförmigen Saugöffnungen verlaufende Drehachse ist ein plattenförmiges Schließelement im Innenraum verschwenkbar gelagert, welches mit seinen beiden wulstförmig verdickten Rändern 20 an einer kreiszylindrischen, konzentrisch zur Drehachse des Schließelements 19 verlaufenden Dichtfläche 21 anliegt. Beide Saugöffnungen sind über Durchbrechungen 22 bzw. 23 in dieser Dichtfläche 21 mit dem Innenraum 18 verbunden. Durch Verschwenkung des Schließelementes 19 kann entweder die Durchbrechung 22 oder die Durchbrechung 23 abgeschlossen werden, so daß die Saugöffnungen gegenüber dem Innenraum des Saugkopfes selektiv verschließar sind. Die Betätigung des Schließelementes 19 erfolgt durch eine eine Seitenwand 6 durchsetzende Welle 24 mit einem Schlitz, in den beispielsweise zum Zweck des Verdrehens ein Geldstück eingesetzt werden kann.The hollow interior 18 of the suction head is connected on the one hand to the suction line 1 via a suitable seal, and on the other hand to the two suction openings 11 and 16 of the suction head. A plate-shaped closing element is pivotally mounted in the interior about an axis of rotation running parallel to the two slot-shaped suction openings, and its two bulged edges 20 abut against a circular-cylindrical sealing surface 21 which is concentric with the axis of rotation of the closing element 19. Both suction openings are connected to the interior 18 via openings 22 and 23 in this sealing surface 21. By pivoting the closing element 19, either the opening 22 or the opening 23 can be closed, so that the suction openings can be selectively closed with respect to the interior of the suction head. The closing element 19 is actuated by a shaft 24 passing through a side wall 6 and having a slot into which a coin can be inserted, for example for the purpose of twisting.

Auf die rohrförmige Saugleitung 1 ist mittels eines elastischen Klips 25 eine Sprühdüse 26 elastisch aufsteckbar, die mit einer flexiblen Förderleitung 27 verbunden ist. Diese führt zu einem handbetätigten Schließventil 28, welches ebenfalls mittels eines elastischen Klips 29 auf die Saugleitung 1 aufgesteckt ist. Das Schließventil 28 ist über eine flexible Leitung 30 mit der in der Zeichnung nicht dargestellten Förderpumpe des. Reinigungsgerätes verbunden.A spray nozzle 26, which is connected to a flexible delivery line 27, can be elastically plugged onto the tubular suction line 1 by means of an elastic clip 25. This leads to a manually operated closing valve 28, which is also attached to the suction line 1 by means of an elastic clip 29. The closing valve 28 is connected via a flexible line 30 to the feed pump (not shown in the drawing) of the cleaning device.

Durch die Verwendung elastischer Klips können Sprühdüse und Schließventil mit zugehörigen Leitungen von der Saugleitung gelöst und beispielsweise im Reinigungsgerät aufbewahrt werden.By using elastic clips, the spray nozzle and closing valve with associated lines can be detached from the suction line and stored, for example, in the cleaning device.

Beim normalen Naß- oder Trockensaugbetrieb, bei dem also die Sprühextraktionsvorrichtung nicht verwendet wird, wird der Saugkopf mit der Unterseite auf die zu reinigende Fläche aufgelegt, die Schwenkverbindung zwischen Saugleitung 1 und Saugkopf 3 wird nicht arretiert, so daß die beiden Teile frei gegeneinander verschwenkbar sind. Das Schließelement 19 wird so verdreht, daß die Saugöffnung 16 in der Stirnwand 9 verschlossen ist (Figur 2). In dieser Betriebsstellung kann der Saugkopf in herkömmlicher Weise zum Naß-oder Trockensaugen verwendet werden, wobei die Bedienungsperson den Winkel der Saugleitung gegenüber dem Saugkopf beliebig verstellen kann. Der Saugkopf gleitet dabei auf den Kufen 12, wobei die Saugöffnung durch die Dichtlippe und die Borstenleiste zur Vorder- und Rückseite weitgehend abgeschlossen ist, trotzdem aber den Eintritt eines Luftstromes ermöglicht, der Schmutzteilchen mitreißt.In normal wet or dry suction operation, in which the spray extraction device is not used, the suction head is placed with the underside on the surface to be cleaned, the swivel connection between suction line 1 and suction head 3 is not locked, so that the two parts can be freely pivoted against each other . The closing element 19 is rotated so that the suction opening 16 in the end wall 9 is closed (Figure 2). In this operating position, the suction head can be used in a conventional manner for wet or dry suction, the operator being able to adjust the angle of the suction line relative to the suction head as desired. The suction head slides on the runners 12, the suction opening being largely closed off by the sealing lip and the bristle strip on the front and rear, but nevertheless allowing the entry of an air flow which entrains dirt particles.

Beim Naß- und Trockensaugen sind Sprühdüse, Schließventil und zugehörige Leitungen von der Saugleitung abgenommen.When wet and dry vacuuming, the spray nozzle, closing valve and associated lines are removed from the suction line.

Wenn die Umrüstung auf Sprühextraktionsbetrieb gewünscht wird, werden die Sprühdüse und die Schließventile mittels ihrer Klipse auf die Saugleitung 1 aufgesteckt. Der Saugkopf muß zum Sprühextraktionsbetrieb hochkant gestellt werden, das heißt er wird mit seiner Stirnwand 9 gegen die zu reinigende Fläche gerichtet. Um ihn in dieser Stellung führen zu können, und um andererseits eine bequeme Arbeitsrichtung der Saugleitung 1 zu erreichen, wird der Winkel zwischen Saugkopf und Saugleitung entsprechend eingestellt und anschließend mittels des Drehgriffes 10 fixiert. Die Sprühdüse 26 wird so auf die Saugleitung 1'aufgesteckt, daß der von ihr abgegebene Strahl 31 in Ziehrichtung des Sprühkopfes gesehen vor dem Sprühkopf auf die zu reinigende Fläche auftrifft (Figur 1). Außerdem wird das Schließelement 19 so verstellt, daß nunmehr die Saugöffnung 11 an der Unterseite verschlossen und die Saugöffnung 16 an der Stirnseite geöffnet ist. In dieser Stellung kann der hochkant stehende Saugkopf wegen der Winkelfeststellung mittels der Saugleitung 1 kräftig gegen die zu reinigende Fläche gedrückt werden, wobei gleichzeitig die Bedienungsperson den Saugkopf zu sich heranziehen kann. Auf diese Weise wird die vorher auf die zu reinigende Fläche aufgesprühte Flüssigkeit zusammen mit dem gelösten Schmutz in den Saugkopf eingesaugt.If the conversion to spray extraction mode is desired, the spray nozzle and the closing valves are attached to the suction line 1 by means of their clips. The suction head must be placed upright for spray extraction operation, that is, it is directed with its end wall 9 against the surface to be cleaned. In order to be able to guide it in this position and, on the other hand, to achieve a comfortable working direction of the suction line 1, the angle between the suction head and the suction line is set accordingly and then fixed by means of the rotary handle 10. The spray nozzle 26 is plugged onto the suction line 1 ′ in such a way that the jet 31 emitted by it strikes the surface to be cleaned in front of the spray head as seen in the direction of pull of the spray head (FIG. 1). In addition, the closing element 19 is adjusted so that the suction opening 11 on the underside is now closed and the suction opening 16 is open on the front side. In this position, the upright suction head can be pressed strongly against the surface to be cleaned by means of the suction line 1 because of the angular detection, and at the same time the operator can pull the suction head towards him. In this way, the liquid previously sprayed onto the surface to be cleaned is sucked into the suction head together with the loosened dirt.

Für beide Betriebsarten, also das Naß- oder Trockensaugen einerseits und das Sprühextraktionsreinigen andererseits, kann somit derselbe Saugkopf verwendet werden, wobei die Umstellung von einer Betriebsart auf die andere nur wenige, einfache Handgriffe erfordert. In beiden Betriebsarten kann der Saugkopf den entsprechenden Anforderungen der jeweiligen Reinigungsart vollständig genügen, da die Saugöffnungen den entsprechenden Betriebsarten angepaßt werden können.The same suction head can thus be used for both modes of operation, i.e. wet or dry vacuuming on the one hand and spray extraction cleaning on the other, the changeover from one operating mode to the other requiring only a few simple operations. In both operating modes, the suction head can fully meet the requirements of the respective cleaning method, since the suction openings can be adapted to the corresponding operating modes.
