Abstract

A suction cleaning apparatus for wet cleaning, which has a receiving space (2) which is closed by a detachable housing cover (5) and into which a separate container (4) can be inserted. A blower unit which generates the corresponding suction stream is furthermore provided. A liquid pump (11) arranged in the apparatus delivers the cleaning fluid (12), which can be filled into the apparatus, to a spray nozzle through which the cleaning liquid (12) is distributed onto the surface to be cleaned. As a result of the suction stream, this liquid is sucked off again and delivered to the container (4) arranged in the apparatus. In order to achieve a reduction in the apparatus dimensions and improved handling of the apparatus, it is proposed that the container (4) be constructed to be dimensionally stable and the blower unit (7) be accommodated in a housing pot (6) connected to the housing cover (5). The blower unit (7) is suctionally connected to the receiving space (2) via air inlet openings (8) provided directly below the housing cover (5) in the circumferential wall of the housing pot (6). The liquid pump (11) is likewise arranged in the receiving space (2). Suction cleaning apparatuses of this type are used for wet cleaning carpets. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Saugreinigungsgerät, mit einem im Gehäuse des Gerätes ausgebildeten, durch einen abnehmbaren Gehäusedeckel verschließbaren Aufnahmeraum, in den ein gesonderter Behälter einsetzbar ist, ferner mit einem einen Saugstrom erzeugenden Gebläseaggregat, das mit dem Aufnahmeraum in Saugverbindung steht, in den ein außen mit einer Saugdüse verbindbares Saugrohr mündet sowie einer Flüssigkeitspumpe, deren Ansaugrohr in den Aufnahmeraum führt und deren Ausgang mit einer Spritzdüse verbindbar ist.The invention relates to a suction cleaning device, with a receiving space formed in the housing of the device and closable by a removable housing cover, into which a separate container can be inserted, and also with a blower unit that generates a suction flow and is in suction connection with the receiving space externally connectable with a suction nozzle suction pipe and a liquid pump, the suction pipe leads into the receiving space and the outlet can be connected to a spray nozzle.

Ein solches Saugreinigungsgerät ist durch die DE-OS 23 64 772 bekannt. Bei diesem Reinigungsgerät sind die Flüssigkeitspumpe und das Gebläseaggregat aus Sicherheitsgründen über dem Gehäusedeckel angeordnet Und werden nochmals durch einen weiteren haubenartigen Gehäusedeckel abgedeckt. Durch diese Anordnung besitzt das Gerät noch relativ große Abmessungen.Such a suction cleaning device is known from DE-OS 23 64 772. In this cleaning device, the liquid pump and the blower unit are arranged above the housing cover for safety reasons and are covered again by a further hood-like housing cover. Due to this arrangement, the device still has relatively large dimensions.

Der Erfindung liegt die Aufgabe zugrunde, ein Saugreinigungsgerät so auszubilden, daß seine Abmessungen den im Haushalt gebräuchlichen Staubsaugern entsprechen.The invention has for its object to provide a suction cleaning device so that its dimensions correspond to the vacuum cleaners commonly used in the household.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß der Behälter formsteif ausgebildet und das Gebläseaggregat in einem mit dem Gehäusedeckel verbundenen, in den Aufnahmeraum ragenden Gehäusetopf untergebracht ist, dessen Umfangswand unmittelbar unterhalb des Gehäusedeckels mindestens eine Lufteinlaßöffnung aufweist und daß ferner die Flüssigkeitspumpe im Aufnahmeraum angeordnet ist. Durch die Anordnung des Gebläseaggregates in dem in den Aufnahmeraum ragenden Gehäusetopf des Gehäusedeckels wird der Raum im Gerät besser ausgenutzt und es werden somit kleinere Abmessungen für das Saugreinigungsgerät erreicht. Die Verwendung eines formsteifen Behälters ermöglicht nicht nur die Unterbringung des Gebläseaggregates im Innenraum des Saugreinigungsgerätes, sondern erleichtert auch die Handhabung desselben. Ein formsteifer Behälter läßt sich leichter aus dem Gerät herausnehmen als ein elastisches Behältnis.The object is achieved according to the invention in that the container is dimensionally stable and the blower unit is accommodated in a housing pot connected to the housing cover and protruding into the receiving space, the peripheral wall of which has at least one air inlet opening directly below the housing cover and that the liquid pump in Recording room is arranged. By arranging the blower unit in the housing top p f of the housing cover protruding into the receiving space, the space in the device is better utilized and smaller dimensions for the suction cleaning device are thus achieved. The use of a dimensionally stable container not only enables the blower unit to be accommodated in the interior of the suction cleaning device, but also facilitates its handling. A rigid container is easier to remove from the device than an elastic container.

Die Handhabung des Gerätes wird ferner auch dadurch erleichtert, daß der Behälter in einen in den Aufnahmeraum einsetzbaren Zwischenbehälter eingesetzt ist. Durch einen solchen Zwischenbehälter wird verhindert, daß der Behälter durch Flüssigkeit benetzt wird und somit beim Herausnehmen tropft. Nach einer weiteren Ausgestaltung der Erfindung kann das Saugreinigungsgerät auch zum Aufsaugen von trockenem Schmutz verwendet werden. Dies wird auf einfache Weise dadurch erreicht, daß an der Außenseite des Gehäusetopfes Rippen angeformt sind, auf die ein Filter aufsetzbar ist.The handling of the device is also facilitated in that the container is inserted into an intermediate container that can be inserted into the receiving space. Such an intermediate container prevents the container from being wetted by liquid and thus dripping when it is removed. According to a further embodiment of the invention, the suction cleaning device can also be used to vacuum dry dirt. This is achieved in a simple manner in that ribs are formed on the outside of the housing pot, onto which a filter can be placed.

Anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels wird der Anmeldungsgegenstand nachfolgend näher erläutert.The subject of the application is explained in more detail below on the basis of an exemplary embodiment shown schematically in the drawing.

Es zeigt:

  • Fig. 1 ein Saugreinigungsgerät mit frisch eingefüllter Reinigungsflüssigkeit,
  • Fig. 2 das gleiche Saugreinigungsgerät nach der Aufnahme von Schmutzflüssigkeit,
  • Fig. 3 ein Saugreinigungsgerät in der Verwendung als Trockenreinigungsgerät.
It shows:
  • 1 is a suction cleaning device with freshly filled cleaning liquid,
  • 2 the same suction cleaning device after the absorption of dirty liquid,
  • Fig. 3 is a suction cleaning device in use as a dry cleaning device.

In der Zeichnung ist mit 1 jeweils das Gehäuse eines Saugreinigungsgerätes bezeichnet. Das Gehäuse 1 weist einen Aufnahmeraum 2 auf, in den ein Zwischenbehälter 3 einsetzbar ist, in dem wiederum ein Behälter 4 eingesetzt ist. Das Gehäuse 1 ist durch einen abnehmbaren Gehäusedeckel 5 verschließbar. An dem Gehäusedeckel 5 ist ein Gehäusetopf 6 angeformt, in dem ein Gebläseaggregat 7 angeordnet ist. Unmittelbar unterhalb des Gehäusedeckels 5 weist der Gehäusetopf 6 Lufteinlaßöffnungen 8 auf. An der Außenwand des Gehäusetopfes 6 sind Rippen 9 angeformt. Mit dem Gehäusedeckel 5 ist ferner ein Saugrohr 10 verbunden, das in den Aufnahmeraum 2 mündet und außen mit einer Saugdüse verbindbar ist. Ferner befindet sich in dem Aufnahmeraum 2 eine Flüssigkeitspumpe 11. Durch kleine Pfeile ist der Weg der von dem Gebläseaggregat 7 angesaugten Luft und durch einen gestrichelten Pfeil der Weg des Luftflüssigkeitsgemisches angedeutet.In the drawing, 1 denotes the housing of a suction cleaning device. The housing 1 has a receiving space 2, into which an intermediate container 3 can be inserted, in which a container 4 is in turn inserted. The housing 1 can be closed by a removable housing cover 5. A housing pot 6 is formed on the housing cover 5, in which a blower unit 7 is arranged. The housing pot 6 has air inlet openings 8 directly below the housing cover 5. Ribs 9 are formed on the outer wall of the housing pot 6. A suction pipe 10 is also connected to the housing cover 5, which opens into the receiving space 2 and can be connected externally to a suction nozzle. Furthermore, there is a liquid pump 11 in the receiving space 2. The path of the air sucked in by the blower unit 7 is indicated by small arrows and the path of the air-liquid mixture is indicated by a dashed arrow.

Nach der Darstellung in Fig. 1 ist in den Aufnahmeraum 2 eine Reinigungsflüssigkeit 12 eingefüllt. Auf dieser Reinigungsflüssigkeit 12 schwimmt der den Behälter 4 enthaltende Zwischenbehälter 3. Der Boden 13 des Behälters 4 befindet sich in dieser Lage unmittelbar unter dem Gehäusetopf 6. Durch Einschalten der Flüssigkeitspumpe 11 wird über deren in die Reinigungsflüssigkeit 12 ragendes Ansaugrohr 14 Reinigungsflüssigkeit 12 ange- saugt und über den Ausgang 15 zu einer Spritzdüse gefördert. Durch eine solche Spritzdüse wird die Reinigungsflüssigkeit 12 auf die zu reinigende Fläche aufgetragen und anschließend durch eine mit dem Saugrohr 10 verbundene Saugdüse wieder abgesaugt. Über die nicht dargestellte Saugdüse wird die nunmehr mit Schmutz angereicherte Flüssigkeit zusammen mit der Saugluft in das Gerät eingesaugt und gelangt über das Saugrohr 10 in den Behälter 4. Durch die senkrechte Einführung des Saugrohres 10 in den Behälter 4 wird eine Abscheidung der Saugluft aus dem Flüssigkeitsluftgemisch erreicht. Mit dem Einschalten der Flüssigkeitspumpe sinkt der Spiegel der Reinigungsflüssigkeit 12 und damit auch der Zwischenbehälter 3 mit dem Behälter 4 ab, so daß der Behälter 4 nunmehr mit Schmutzflüssigkeit gefüllt werden kann, ohne daß der Gehäusetopf 6 in die Schmutzflüssigkeit hineinragt.According to the illustration in FIG. 1, a cleaning liquid 12 is filled into the receiving space 2. The intermediate container 3 containing the container 4 floats on this cleaning liquid 12. The bottom 13 of the container 4 is located directly below in this position the housing pot 6. By switching on the liquid pump 11, cleaning liquid 12 is sucked in via its suction pipe 14 projecting into the cleaning liquid 12 and conveyed via the outlet 15 to a spray nozzle. The cleaning liquid 12 is applied to the surface to be cleaned by such a spray nozzle and then sucked off again by a suction nozzle connected to the suction pipe 10. Via the suction nozzle, not shown, the liquid, now enriched with dirt, is sucked into the device together with the suction air and reaches the container 4 via the suction pipe 10. The suction pipe 10 is introduced vertically into the container 4, and the suction air is separated from the liquid-air mixture reached. When the liquid pump is switched on, the level of the cleaning liquid 12 and thus also the intermediate container 3 with the container 4 drops, so that the container 4 can now be filled with dirty liquid without the housing pot 6 protruding into the dirty liquid.

In Fig. 2 ist die Lage des Zwischenbehälters 3 und des Behälters 4 nach völliger Entnahme der Reinigungsflüssigkeit 12 dargestellt. Der Behälter 4 ist in diesem Zustand mit Schmutzflüssigkeit 16 gefüllt. Zum Entleeren des Behälters 4 wird der Gehäusedeckel 5 zusammen mit dem angebauten Gebläseaggregat 7 und dem Saugrohr 10 abgenommen. Danach kann der Behälter 4 ungehindert aus dem Aufnahmeraum 2 herausgehoben und entleert werden. Durch den Zwischenbehälter 3 ist ein unmittelbarer Kontakt des Behälters 4 mit der Reinigungsflüssigkeit verhindert, so daß dieser vollkommen trocken bleibt und damit beim Entleeren nicht tropft.2 shows the position of the intermediate container 3 and the container 4 after the cleaning liquid 12 has been completely removed. The container 4 is filled with dirty liquid 16 in this state. To empty the container 4, the housing cover 5 is removed together with the attached blower unit 7 and the suction pipe 10. The container 4 can then be lifted out of the receiving space 2 and emptied. The intermediate container 3 prevents direct contact of the container 4 with the cleaning liquid, so that it remains completely dry and therefore does not drip when emptied.

In Fig. 3 sind der Zwischenbehälter 3 und der Behälter 4 aus dem Aufnahmeraum 2 herausgenommen. Auf die Rippen 9 des Gehäusetopfes 6 ist ein Filter 17 aufgesetzt. Durch eine solche Umrüstung kann das Saugreinigungsgerät zum Trockensaugen verwendet werden. In diesem Falle wird über das Saugrohr 10 lediglich mit Schmutz angereicherte Luft eingesaugt. Durch das Filter 17 wird der Schmutz im Aufnahmeraum 2 zurückgehalten und die Luft kann wiederum durch das Gebläseaggregat 7 über die Luftauslaßöffnungen 8 nach außen gefördert werden.In Fig. 3, the intermediate container 3 and the container 4 are removed from the receiving space 2. A filter 17 is placed on the ribs 9 of the housing pot 6. With such a retrofit, the vacuum cleaning device can be used for dry vacuuming. In this case, only air enriched with dirt is sucked in via the suction pipe 10. The dirt 17 is retained in the receiving space 2 by the filter 17 and the air can in turn be conveyed to the outside by the blower unit 7 via the air outlet openings 8.
