Abstract

Bei einem Bodenreinigungsgerät, das ein an einer Bodenfläche angreifendes Reinigungswerkzeug, einen Reinigungsflüssigkeits- sowie einen Schmutzflüssigkeitsbehälter und ein Saugaggregat umfaßt, wird eine Abdichtung vorgeschlagen. Erfindungsgemäß wird auf der Motorwelle turbinenseitig eine Schleuderscheibe vorgesehen, die an einer Hülse befestigt ist, die fest mit der Motorwelle verbunden ist und die Öffnung vom Turbinenraum zum Motorraum durchsetzt und daß die Zwischenwand turbinenseitig eine Fangrinne aufweist, wobei der Durchmesser der turbinenseitigen Wand der Fangrinne kleiner oder gleich dem Durchmesser des Schleuderrades ist und wobei die Fangrinne zwischen dem Schleuderrad und der Zwischenwand angrenzend an die Durchgangsöffnung für die Motorwelle angeordnet ist.

Figure 00000001
In the case of a floor cleaning device which comprises a cleaning tool engaging on a floor surface, a cleaning liquid and a dirty liquid container and a suction unit, a seal is proposed. According to the invention, a centrifugal disc is provided on the engine shaft on the turbine side, which is fastened to a sleeve which is fixedly connected to the engine shaft and passes through the opening from the turbine space to the engine compartment and that the intermediate wall on the turbine side has a gutter, the diameter of the turbine-side wall of the gutter being smaller or is equal to the diameter of the centrifugal wheel and wherein the gutter is arranged between the centrifugal wheel and the intermediate wall adjacent to the passage opening for the motor shaft.
