Embodiment Construction
[0062] An advantageous embodiment of the portable hard-surface cleaning device according to the invention is shown schematically in the drawing, which is designated as a whole by the reference numeral 10 . Liquids can be removed and sucked up from hard surfaces, especially window panes, with the aid of the portable hard surface cleaning device 10 . In this case, the hard-surface cleaning device 10 can be moved along the hard surface by the user in the manner of a manual window scraper. Accordingly, the portable hard surface cleaning device 10 is configured as a window cleaner.
[0063] The hard-surface cleaning device 10 comprises a base housing 12 which is configured with a handle 14 and, on the front side of the base housing facing away from the handle 14 , has a tank receptacle 16 into which a dirty liquid tank 18 is inserted. The dirty liquid tank 18 is held detachably in the tank receptacle 16 and can be removed by the user from the tank receptacle 16 and subsequently in...

The invention relates to a portable hard-surface cleaning device (10) for pulling off and suctioning liquid from a hard surface, in particular from a window pane, comprising a suction nozzle (136) having a suction opening (140), on which suction opening at least one pull-off lip (142, 144) is arranged, a drive chamber (19), in which a suction unit (22) is arranged, which has a suction turbine (24) and an electric motor (26) and which has a flow connection to the suction nozzle (136) in order to suck in a liquid-air mixture from the suction opening (140), a separation chamber (128), which is arranged in the flow path between the suction nozzle (136) and the suction unit (22) and in which a separating apparatus (130, 132) for separating liquid from the liquid-air mixture is arranged, and a dirty-liquid receptacle (18) for receiving the separated liquid. In order to be able to produce the hard-surface cleaning device (10) more economically, a motor housing (38) is arranged in the drive chamber (19), which motor housing surrounds the electric motor (26) and at least one rechargeable battery (48) and battery-monitoring electronics (49) in a spray-water-tight manner and which motor housing forms a lower housing part (32) of a turbine housing (28) arranged in the drive chamber (19), which lower housing part is supported by a support wall (64, 66), a turbine wheel (34) being rotatably supported in the turbine housing.
Description
technical field [0001] The present invention relates to a portable hard surface cleaning device for removing and suctioning liquid from hard surfaces, especially from window panes, comprising a suction nozzle with a suction opening, a drive chamber, a separation chamber and a A dirty liquid container for liquids, wherein at least one removal lip is arranged on the suction opening; a suction unit is arranged in the drive chamber, the suction unit has a suction turbine and an electric motor, and the suction unit is in fluid contact with the suction nozzle In a flow connection for sucking up a liquid-air mixture from the suction opening; a separation chamber is positioned in the flow path between the suction nozzle and the suction unit and a separation device is arranged in the separation chamber for separating the liquid-air mixture out of the liquid. Background technique [0002] Such hard-surface cleaning devices are known, for example, from EP 2 237 711 B1 as well as from ...
