Description

Die Erfindung betrifft ein Bodenpflegegerät gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a floor care device according to the preamble of the first claim.

Ein bekanntes Bodenpflegegerät dieser Art (DE-GM 76 36 603) ist an seiner dem zu reinigenden Teppich zugewandten Bodenwand mit einer Auftragsvorrichtung für Reinigungsmittel ausgestattet, das mittels einer Gummilippe auf den Teppich aufgetragen wird. In der Hauptfahrtrichtung des Gerätes folgt nach dieser Auftragsvorrichtung eine in den Teppichflor eingreifende angetriebene Scheibenwalze, welche das aufgetragene Reinigungsmittel in den Teppichflor einarbeitet. Danach folgt eine Aufnahmevorrichtung, welche die mit abgelösten Schmutzpartikeln vermischte Reinigungsflüssigkeit von der Teppichoberfläche durch einen Luftstrom abträgt. Von Nachteil ist bei diesem Aufbau, daß mit einer derart ausgebildeten Auftragsvorrichtung erfahrungsgemäß Reinigungsflüssigkeit in solcher Menge aufgetragen wird, daß eine starke Durchnässung des Teppichs eintritt und eine entsprechende hohe Flüssigkeitsmenge trotz sofortier Absaugung im Teppich verbleibt. Hierdurch ergibt sich eine sehr lange Wartezeit zwischen dem Reinigungsvorgang des Teppichs und der zumindest weitgehenden Abtrocknung des Teppichs. Eine entsprechend lange Zeit ist dann der betreffende Raum nicht zu begehen.A known floor care device of this type (DE-GM 76 36 603) is equipped on its floor wall facing the carpet to be cleaned with an application device for cleaning agents which is applied to the carpet by means of a rubber lip. In the main direction of travel of the device, this application device is followed by a driven disk roller which engages in the carpet pile and which incorporates the applied cleaning agent into the carpet pile. This is followed by a pick-up device which removes the cleaning liquid mixed with detached dirt particles from the carpet surface by means of an air stream. The disadvantage of this structure is that experience has shown that cleaning liquid is applied in such an amount with such an application device that the carpet becomes very wet and a correspondingly high amount of liquid remains in the carpet despite immediate suction. This results in a very long waiting time between the cleaning process of the carpet and the at least extensive drying of the carpet. The room in question is then not accessible for a correspondingly long time.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Bodenpflegegerät gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch welche eine Verminderung der Durchfeuchtung der zu reinigenden Fußbodenfläche erzielt wird.The invention has for its object to take measures in a floor care device according to the preamble of the first claim, through which a reduction in the moisture content of the floor surface to be cleaned is achieved.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Bei einer Ausgestaltung eines Bodenpflegegerätes gemäß der Erfindung wird eine für den Reinigungsvorgang gerade ausreichende Menge des Reinigungsfluids in mikrofein zerstäubter Tröpchenform auf die zu reinigende Fußbodenfläche aufgesprüht, die lediglich zu einer Benetzung dieser Fußbodenfläche und bei einem Teppich zu dessen Benetzung an seiner Oberseite ausreicht. Dabei dringt das Reinigungsfluid durch seine nebelartige Form praktisch nicht in den Teppichflor ein und wird bei einem entsprechend ausgebildeten Bodenpflegegerät erst durch eine nachfolgende Bürstwalze in den Teppichflor eingebürstet bzw. auf einen glatten Boden aufgerieben, um durch diese mechanische Einwirkung eine erhöhte Schmutzablösung zu erreichen. Bei einem Teppich wird somit das Reinigungsfluid aufgrund der geringen Auftragsmenge in feinstverteilter Form nicht in den Teppichgrund eingeschwemmt und erst durch die Bürstwalze in geringster Menge in den Flor eingearbeitet, so daß nur die einzelnen Teppichfäden benetzt werden. Der hierfür verwendete Aerosolzerstäuber erzeugt Tröpchen in der Größe zwischen 15 Mikrometer bis 150 Mikrometer Durchmesser. Das Reinigungsfluid ist dabei vorzugsweise eine Flüssigkeit, die schmutzablösende Tenside enthält. Die dabei je Quadratmeter auf die Fußbodenfläche aufzubringende Menge des Reinigungsfluids beträgt insbesondere etwa 0,1 Liter je Quadratmeter und kann zwischen 50 Kubikzentimetern und 120 Kubikzentimetern im Bereich zwischen niedrigem und hohem Flor liegen. Die am Gerätegehäuse festgesetzte Auftragsvorrichtung wird dabei mit einer Geschwindigkeit zwischen 0,1 Meter und 0,2 Meter je Sekunde über die Fußbodenfläche geführt, um einen alle Flächenteile erreichenden Fluidauftrag zu erreichen. Die Auftragsvorrichtung kann dabei vorzugsweise einen durch Schwingungen angetriebenen Zerstäuber aufweisen, der insbesondere einen in Schwingungen versetzten Piezokristall als Zerstäubungselement besitzt.In one embodiment of a floor care device according to the invention, a quantity of the cleaning fluid in a microfine atomized droplet form which is just sufficient for the cleaning process is sprayed onto the floor surface to be cleaned, which is sufficient only for wetting this floor surface and, in the case of a carpet, for wetting it on its upper side. Due to its mist-like shape, the cleaning fluid practically does not penetrate the carpet pile and is only brushed into the carpet pile with a suitably designed floor care device by a subsequent brush roller or rubbed onto a smooth floor in order to achieve increased dirt detachment through this mechanical action. In the case of a carpet, the cleaning fluid is not washed into the carpet base due to the small amount applied in finely divided form and is only incorporated into the pile in the smallest amount by the brush roller, so that only the individual carpet threads are wetted. The aerosol atomizer used for this creates droplets in the size between 15 microns to 150 microns in diameter. The cleaning fluid is preferably a liquid that contains dirt-removing surfactants. The amount of cleaning fluid to be applied per square meter to the floor area is in particular about 0.1 liters per square meter and can be between 50 cubic centimeters and 120 cubic centimeters in Range between low and high pile. The application device attached to the device housing is guided over the floor surface at a speed between 0.1 meters and 0.2 meters per second in order to achieve a fluid application reaching all parts of the surface. The application device can preferably have an atomizer driven by vibrations, which in particular has a piezo crystal set in vibration as the atomizing element.

Im Praktischen Betrieb des Bodenpflegegeräts wird mittels der Auftragsvorrichtung das Reinigungsfluid in mikrozerstäubter Form auf die zu reinigende Fußbodenfläche unter Verschieben des Gerätes aufgetragen und nachfolgend durch die Bürstenwalze in innigen Kontakt mit der Fußbodenfläche und ggf. den Florhaaren eines Teppich in innigen Kontakt gebracht, wonach eine nachfolgende Aufsaugvorrichtung einen Teil des Reinigungsfluids zusammen mit dem gelösten Schmutz aufnimmt. Infolge der geringen auf die Fußbodenfläche aufgebrachten Reinigungsmittelmenge wird insbesondere die Durchfeuchtung eines Teppichs auf ein Minimum reduziert und damit auch die Zeit bis zur Wiederbegehbarkeit wesentlich verkürzt. Dabei ist es zweckmäßig, paarweise die Auftragsvorrichtung und die Bürstenwalze und zeitverzögert danach die Bürstenwalze und die Absaugvorrichtung zu aktivieren, so daß die aufgetragene Reinigungsflüssigkeit über einen Zeitraum ihre schmutzlösende Wirkung entfalten kann und erst in einem späteren Arbeitsgang aufgenommen wird. Dabei ist es zweckmäßig, die Absaugvorrichtung als Schlitzdüse eng benachbart nach der Bürstenwalze vorzusehen, um die von der Bürstenwalze hochgeschleuderten Schmutz- und Flüssigkeitspartikel vor einer erneuten Ablagerung auf der Fußbodenfläche durch den Absaugluftstrom abzuführen.In practical operation of the floor care device, the application fluid is used to apply the cleaning fluid in micro-atomized form to the floor surface to be cleaned while moving the device, and then to bring the brush roller into intimate contact with the floor surface and possibly the pile hair of a carpet, after which a subsequent one Suction device absorbs part of the cleaning fluid together with the loosened dirt. As a result of the small amount of cleaning agent applied to the floor area, the moisture penetration of a carpet in particular is reduced to a minimum and the time until it can be walked on is also significantly shortened. It is expedient to activate the application device and the brush roller in pairs and then after a time delay the brush roller and the suction device, so that the applied cleaning liquid can develop its dirt-removing effect over a period of time and is only taken up in a later operation. It is expedient to provide the suction device as a slot nozzle closely adjacent to the brush roller in order to remove the dirt and liquid particles thrown up by the brush roller before being deposited again on the floor surface by the suction air flow.
