Description
Die Erfindung bezieht sich auf eine Bodenreinigungsmaschine gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a floor cleaning machine according to the preamble of
Beim Reinigen mit einer Bodenreinigungsmaschine, z.B. einer Scheuersaugmaschine wird das zur Reinigung auf den Boden aufgebrachte Wasser mit einer sogenannten Saugleiste wieder abgesogen. Dazu wird mittels eines Sauggebläses ein starker Luftstrom erzeugt (wie bei einem Staubsauger), welcher das Wasser und den gelösten Schmutz mitreisst. Dieses Luft-Wassergemisch wird in den Schmutzwassertank der Maschine geleitet. Im Schmutzwassertank wird die Luft wieder vom Wasser getrennt und über das Sauggebläse an die Umgebung abgegeben.When cleaning with a floor cleaning machine, e.g. a scrubber-drier, the water applied to the floor for cleaning is sucked off again with a suction strip. For this purpose, a strong air flow is generated by means of a suction fan (as in a vacuum cleaner), which entrains the water and the dissolved dirt. This air-water mixture is directed into the wastewater tank of the machine. In the waste water tank, the air is again separated from the water and discharged via the suction fan to the environment.

Die Absaugvorrichtung 11 zum Absaugen von Schutzwasser umfasst im Wesentlichen den zweiten Tank 14 für das Schmutzwasser, die Saugleiste 12, welche in einer Vorwärtsbewegungsrichtung der Bodenreinigungsmaschine 1 betrachtet hinter der mindestens einen Reinigungsvorrichtung 9 am Maschinengehäuses 16 angeordnet ist, ein Sauggebläse 13 mit einer Saugöffnung 19 und einer Austrittsöffnung 20 und eine Abscheidevorrichtung 15, welche zwischen der Saugleiste 12 und der Saugöffnung 19 des Sauggebläses 13 angeordnet ist. Die Abscheidevorrichtung 15 kann beispielhaft und nicht einschränkend als Schwerkraftabscheider ausgebildet und im zweiten Tank 14 angeordnet sein, so dass das Schmutzwasser direkt im zweiten Tank 14 durch die Schwerkraft von dem durch die Saugleiste 12 abgesaugten Luft/Schmutzwassergemisch getrennt und in den zweiten Tank 14 abgeführt wird. Dabei wird das Luft/Schmutzwassergemisch von der Saugleiste 12 über eine zweite Rohr- oder Schlauchverbindung 26 in die Abscheidevorrichtung 15 geführt. Die Luft wird nach dem Abscheiden des Schmutzwassers mittels einer dritten Rohr- oder Schlauchverbindung 27 von der Abscheidevorrichtung 15 zum Sauggebläse 13 geführt und von dort in den Abluftkanal 21 und durch den ersten und zweiten Filter 17;22 an die Umgebung abgegeben.The
