Abstract

The invention relates to a vacuum cleaner ancillary device (1) which comprises a suction tube (2), a mouthpiece (3) which may be connected to it and a container (4) for cleaning fluid fitted on the suction tube, in which ancillary device (1) a distribution strip (7) linked to the container so as to conduct liquid and a movably mounted applicator member assigned to it are provided in the mouthpiece housing and additionally suction slits (10) are formed on both longitudinal sides of the applicator member. The force required to move the ancillary device (1) backwards and forwards may be kept low since the applicator member is designed as a pivotable roller made of sponge-like material and the roller space (5) surrounding the roller (6) is pressure-isolated from the suction slits (10) and subjected to ambient pressure. <IMAGE>

Description

Die Erfindung betrifft ein an einen Staubsauger anschließbares Zusatzgerät gemäß dem Oberbegriff des Anspruches 1.The invention relates to an attachable to a vacuum cleaner according to the preamble of claim 1.

Ein solches Zusatzgerät ist durch die DE-AS 1 503 858 bekannt. Bei diesem Gerät besteht der Auftragskörper aus zwei schwenkbar angeordneten Bürsten, die durch ihren Eingriff in den Teppich beim Hin- und Herbewegen des Zusatzgerätes entsprechend verschwenkt werden. Durch den Eingriff der Bürsten ergibt sich ein hoher Schiebewiderstand. Zu dessen Erhöhung trägt außerdem die relativ große, vom Unterdruck beaufschlagte Fläche des Saugmundstückes weiter bei.Such an additional device is known from DE-AS 1 503 858. In this device, the application body consists of two pivotably arranged brushes, which are pivoted accordingly by their engagement in the carpet when the auxiliary device is moved back and forth. The engagement of the brushes results in a high sliding resistance. The relatively large surface area of the suction mouthpiece, which is acted upon by the vacuum, further contributes to its increase.

Der Erfindung liegt die Aufgabe zugrunde, ein Zusatzgerät der gattungsgemäßen Art derart auszubilden, daß die für das Hin- und Herbewegen des Gerätes aufzuwendende Kraft möglichst gering und das Gerät insgesamt leicht zu bedienen ist.The invention has for its object to provide an additional device of the generic type in such a way that the force to be used for moving the device back and forth is as low as possible and the device as a whole is easy to use.

Die Lösung der gestellten Aufgabe gelingt durch die kennzeichnenden Merkmale des Anspruches 1. Durch das Abrollen der Walze auf dem zu reinigenden Teppich ist der Schiebewiderstand beim Hin- und Herbewegen des Zusatzgerätes auf ein Minimum reduziert. Der Unterdruck wirkt infolge der Beaufschlagung des Walzenraumes mit dem Umgebungsdruck nur noch auf eine wesentlich kleinere Fläche des Mundstückes, so daß das Mundstück nicht mehr so stark an den Teppich angepreßt wird und damit die notwendige Schiebekraft weiter vermindert ist.The problem is solved by the characterizing features of claim 1. By rolling the roller on the carpet to be cleaned, the sliding resistance when the auxiliary device is moved back and forth is reduced to a minimum. The negative pressure acts due to the action of the roller space with the ambient pressure only on a much smaller area of the mouthpiece, so that the mouthpiece is no longer pressed so strongly against the carpet and thus the necessary pushing force is further reduced.

Dadurch, daß der Behälter abnehmbar am Saugrohr angeordnet ist, ist eine leichtere Befüllung mit Reinigungsflüssigkeit möglich.The fact that the container is removably arranged on the suction pipe makes it easier to fill with cleaning fluid.

Ein gleichmäßiger Flüssigkeitsaustritt unabhängig vom jeweiligen Flüssigkeitsstand im Behälter wird dadurch erreicht, daß der Behälter in einen am Saugrohr angeordneten Aufnahmerahmen einsetzbar ist, der ein durch eine der Gewichtskraft des Behälters entgegenwirkende Kraft höhenverstellbares Bodenteil aufweist, auf dem der Behälter aufruht. Während des Entleerungsvorganges wird das Bodenteil infolge der Gewichtsverminderung des Behälters durch die entgegenwirkende Kraft entsprechend angehoben. Damit bleibt der Flüssigkeitsspiegel gegenüber der Verteilerleiste praktisch bis zur vollständigen Entleerung des Behälters auf gleicher Höhe, wordurch der gleichmäßige Zulauf der Flüssigkeit zur Verteilerleiste gewährleistet ist.A uniform liquid outlet regardless of the respective liquid level in the container is achieved in that the container can be inserted into a receiving frame arranged on the suction pipe, which has a height-adjustable bottom part on which the container rests by a force counteracting the weight of the container. During the emptying process, the bottom part is raised accordingly due to the reduction in weight of the container by the counteracting force. This means that the liquid level remains at the same level compared to the distributor bar until the container is completely emptied, which ensures that the liquid flows uniformly to the distributor bar.

Im Bodenteil des Aufnahmeraumes ist zweckmäßigerweise eine über eine elastische Leitung flüssigkeitsleitend mit der Verteilerleiste verbundene Anschlußöffnung vorgesehen. An diese Anschlußöffnung kann der Behälter mit seiner entsprechend ausgebildeten Auslaßöffnung beim Einsetzen in den Aufnahmerahmen durch einfaches Einstecken angeschlossen werden.In the bottom part of the receiving space there is expediently a connection opening which is connected to the distributor bar in a liquid-conducting manner via an elastic line. The container with its appropriately designed outlet opening can be connected to this connection opening by inserting it into the receiving frame.

Bei Arbeitsunterbrechungen ist es üblich, das an das Mundstück angekoppelte Saugrohr auf dem Zimmerboden abzulegen. Ein Auslaufen der Reinigungsflüssigkeit läßt sich hierbei dadurch vermeiden, daß die mit der Verteilerleiste flüssigkeitsleitend verbindbare Auslaßöffnung des Behälters auf der dem Mundstück zugekehrten Seite im Bereich der vom Saugrohr entfernter liegenden Gehäusekante des Behälters angeordnet ist.When work is interrupted, it is customary to place the suction pipe coupled to the mouthpiece on the floor of the room. Leakage of the cleaning liquid can be avoided here by arranging the outlet opening of the container, which can be connected to the distributor bar in a liquid-conducting manner, on the side facing the mouthpiece in the region of the housing edge of the container which is further away from the suction pipe.

Eine weitere vorteilhafte Ausgestaltung des Erfindung ist gegenstand des Anspruchs 6.Another advantageous embodiment of the invention is the subject of claim 6.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt:

FIG 1
ein Zusatzgerät in schematischer Darstellung,
FIG 2
eine Ausführungsform des Mundstückes eines Zusatzgerätes,
FIG 3
einen Aufnahmerahmen für einen Reinigungsflüssigkeitsbehälter,
FIG 4

The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows:
FIG. 1
an additional device in a schematic representation,
FIG 2
one embodiment of the mouthpiece of an additional device,
FIG 3
a receiving frame for a cleaning liquid container,
FIG 4
a leak-proof embodiment of a cleaning liquid container.

Mit 1 ist ein Zusatzgerät bezeichnet, das ein Saugrohr 2, ein an dieses angestecktes Mundstück 3 und einen abnehmbar am Saugrohr 2 angeordneten Behälter 4 für eine Reinigungsflüssigkeit aufweist. Im Inneren des Gehäuses des Mundstückes 3 ist in einem Walzenraum 5 eine aus schwammartigem Material, z.B Schaumstoff, bestehende Walze 6 drehbar gelagert. Der Walzenraum 5 kann an beiden Seiten vollständig offen oder doch zumindest mit Öffnungen versehen sein, so daß im Walzenraum 5 Umgebungsdruck herrscht. Über der Walze 6 befindet sich am Gehäuse des Mundstückes 3 eine Verteilerleiste 7, die über ein Leitungsstück 8 mit einer am Behälter 4 ausgebildeten Auslaßöffnung 9 in flüssigkeitsleitender Verbindung steht. Die Verteilerleiste 7 weist entsprechende Durchtrittsöffnungen auf, über die die Reinigungsflüssigkeit von der Verteilerleiste 7 auf die Walze 6 gelangt.1 designates an additional device which has a suction pipe 2, a mouthpiece 3 plugged onto this and a container 4 for a cleaning liquid which is arranged detachably on the suction pipe 2. In the interior of the housing of the mouthpiece 3, a roller 6 made of sponge-like material, e.g. foam, is rotatably mounted in a roller chamber 5. The roller chamber 5 can be completely open on both sides or at least be provided with openings so that there is ambient pressure in the roller chamber 5. Above the roller 6 there is a distributor bar 7 on the housing of the mouthpiece 3, which is in liquid-conducting connection via a line piece 8 with an outlet opening 9 formed on the container 4. The distributor bar 7 has corresponding passage openings through which the cleaning liquid passes from the distributor bar 7 to the roller 6.

An der Vorder- und/oder Rückseite des Mundstückes 3 sind sich über die ganze Breite des Mundstückes erstreckende Absaugschlitze 10 vorgesehen, die strömungsmäßig mit dem an das Saugrohr 2 anschließbaren Saugstutzen 11 des Mundstückes 3 in Verbindung stehen. Die Absaugschlitze 10 münden in der unteren Begrenzungsebene 12 des Mundstückes 3. Die Walze 6 ist dagegen so angeordnet, daß sie im abgehobenen Zustand des Mundstückes 3 über die untere Begrenzungsebene 12 vorsteht. Damit wird die Walze 6 bei der Benutzung des Gerätes gegen den Teppich gepreßt und entsprechend zusammengequetscht, so daß die Reinigungsflüssigkeit bzw. der Reinigungsschaum 6 auf den Teppich herausgedrückt wird.On the front and / or rear side of the mouthpiece 3 there are suction slits 10 which extend over the entire width of the mouthpiece and are in flow connection with the suction nozzle 11 of the mouthpiece 3 which can be connected to the suction pipe 2. The suction slots 10 open in the lower boundary plane 12 of the mouthpiece 3. The roller 6, however, is arranged so that it protrudes beyond the lower boundary plane 12 when the mouthpiece 3 is lifted off. So that the roller 6 is pressed against the carpet when using the device and squeezed accordingly, so that the cleaning liquid or the cleaning foam 6 is pressed out onto the carpet.

Wird eine schaumbildende Reinigungsflüssigkeit verwendet, so trägt das beim Hin- und Herbewegen des Zusatzgerätes erfolgende kontinuierliche Zusammenpressen der Walze 6 auf der dem Teppich zugekehrten Seite und das entsprechende Entspannen auf der gegenüberliegenden Seite zur Erzeugung des Reinigungsschaumes bei.If a foam-forming cleaning liquid is used, the continuous compression of the roller 6 on the side facing the carpet and the corresponding relaxation on the opposite side, when the additional device is moved back and forth, contributes to the production of the cleaning foam.

Durch den Anschluß des Zusatzgerätes an einen Staubsauger ist es möglich, die auf den Teppich aufgetragene Reinigungsflüssigkeit wieder abzusaugen. Dies kann gleichzeitig während des Auftragens der Reinigungsflüssigkeit auf den Teppich geschehen. Es besteht aber auch die Möglichkeit, zunächst nur die Reinigungsflüssigkeit aufzutragen und erst nach einer gewissen Einwirkungszeit abzusaugen. Dabei kann dann der Behälter 4 vom Saugrohr 2 abgenommen werden, so daß das Zusatzgerät handlicher wird. Der Behälter 4 kann aber auch zum leichteren Befüllen mit Reinigungsflüssigkeit vom Saugrohr abgenommen werden.By connecting the additional device to a vacuum cleaner, it is possible to vacuum the cleaning liquid applied to the carpet again. This can be done simultaneously while the cleaning liquid is being applied to the carpet. However, there is also the option of initially only applying the cleaning liquid and only vacuuming it off after a certain exposure time. The container 4 can then be removed from the suction pipe 2, so that the additional device becomes more manageable. The container 4 can also be removed from the suction pipe for easier filling with cleaning fluid.

Bei dem in FIG 2 dargestellten Mundstück 3 sind im Walzenraum 5 zwei schräg angeordnete Wandteile 13 vorgesehen, die am Umfang der Walze 6 anliegen und mit ihren oberen Enden 14 an die Verteilerleiste anschließen. Hierdurch entsteht über der Walze 6 ein dachförmiger Stauraum 15, in dem sich eine zum Tränken der Walze 6 ausreichende Menge von Reinigungsflüssigkeit ansammeln kann.In the mouthpiece 3 shown in FIG 2, two obliquely arranged wall parts 13 are provided in the roller chamber 5, which abut the circumference of the roller 6 and connect with their upper ends 14 to the distributor strip. This creates a roof-shaped storage space 15 above the roller 6, in which a sufficient amount of cleaning liquid can be collected to impregnate the roller 6.

Die FIG 3 zeigt einen am Saugrohr 2 anbringbaren Aufnahmerahmen 16 für den Behälter 4. Dieser Aufnahmerahmen 16 weist ein höhenverstellbares Bodenteil 17 auf. Unterhalb dieses Bodenteiles 17 ist eine Feder 18 in dem Aufnahmerahmen 16 angeordnet, die das Bodenteil 17 gegen die Gewichtskraft des Behälters 4 nach oben drückt. Die Feder 18 ist so bemessen, daß das Bodenteil 17 etwa um den gleichen Betrag um den der Flüssigkeitspegel beim Einsatz des Zusatzgerätes 1 absinkt, angehoben wird. Damit gelangt die Reinigungsflüssigkeit während des gesamten Entleerungsvorganges des Behälters 4 mit dem gleichen Druck zur Verteilerleiste 7, wordurch eine gleichmäßige Verteilung der Reinigungsflüssigkeit während des gesamten Arbeitsvorganges gewährleistet ist.3 shows a receptacle frame 16 for the container 4 which can be attached to the suction pipe 2. This receptacle frame 16 has a height-adjustable base part 17. Below this base part 17, a spring 18 is arranged in the receiving frame 16, which presses the base part 17 upwards against the weight of the container 4. The spring 18 is dimensioned such that the base part 17 is raised by approximately the same amount by which the liquid level drops when the auxiliary device 1 is used. So that the cleaning liquid gets during the entire emptying process of the container 4 with the same pressure to the distributor bar 7, which ensures a uniform distribution of the cleaning liquid during the entire working process.

Im Bodenteil 17 ist eine Anschlußöffnung 19 vorgesehen, die über eine die Verstellung des Bodenteiles 17 zulassende elastische Leitung 20 mit dem Anschlußstutzen 21 der Verteilerleiste 7 verbindbar ist. Die Anschlußöffnung 19 ist vorteilhafterweise so gestaltet, daß der Behälter 4 durch bloßes Einstecken seiner Auslaßöffnung 9 angeschlossen werden kann.In the bottom part 17 there is a connection opening 19 which can be connected to the connecting piece 21 of the distributor bar 7 via an elastic line 20 which allows the adjustment of the bottom part 17. The connection opening 19 is advantageously designed so that the container 4 can be connected simply by plugging in its outlet opening 9.

In FIG 4 ist eine auslaufsichere Ausführungsform des Behälters 4 dargestellt. Wie zu erkennen, ist die Auslaßöffnung 9 auf der dem Mundstück 3 zugewandten Seite 22 des Behälters im Bereich von dessen zum Saugrohr 2 entfernter liegenden Gehäusekante 23 angeordnet. Wird das Saugrohr 2 bei einer Unterbrechung des Reinigungsvorganges auf den Zimmerboden abgelegt, dann befindet sich die Auslaßöffnung 9 über dem Flüssigkeitsspiegel in dem Behälter 4 und es kann keine Reinigungsflüssigkeit während der Arbeitsunterbrechung auslaufen. Es bedarf somit keines gesondert zu betätigenden Absperrorganes.4 shows a leak-proof embodiment of the container 4. As can be seen, the outlet opening 9 is arranged on the side 22 of the container facing the mouthpiece 3 in the region of its housing edge 23, which is located further away from the suction pipe 2. If the suction pipe 2 is placed on the floor of the room when the cleaning process is interrupted, then the outlet opening 9 is above the liquid level in the container 4 and no cleaning liquid can run out during the work stoppage. There is therefore no need for a separately operated shut-off device.
