Embodiment Construction

[0041] The drawing schematically shows a portable hard-surface suction device 10 with which liquids can be sucked from hard surfaces, such as window panes. The hard surface suction device 10 can be grasped by the user's hand on the handle 12 and guided over the hard surface along the hard surface according to the type of a conventional wiper with a rubber lip.

[0042] The hard-surface suction device 10 comprises a basic housing 14 which forms the handle 12 and accommodates a suction unit 16 which has a suction turbine 17 and an electric motor 18 . Arranged within the base housing 14 is at least one rechargeable battery 19 for supplying the electric motor 18 with energy. On the bottom side, the basic housing 14 forms a mounting surface 21 , so that the hard-surface suction device 10 stands on a positioning surface.

[0043] On the side facing away from the handle 12, said basic housing 14 constitutes a receiving compartment 23, which accommodates a dirty liquid tank 25 which ...

Abstract

The invention relates to a hard surface vacuum (10) comprising a suction nozzle (80) and a suction unit (16), for vacuuming a liquid-air mixture from a hard surface, and comprising a separating device (72) for separation liquid from the liquid-air mixture, and a waste liquid tank (25) for receiving the separated liquid. In order to obtain a continuous suction flow, regardless of the fill level of the waste liquid tank, without the danger of the liquid that is present in the waste liquid tank of flowing out, a separating chamber (65) is arranged between the suction nozzle (80) and the suction unit, said chamber housing the separating unit and being connected to the waste liquid tank, wherein the flow path from the suction nozzle to the suction unit leads past the waste liquid tank, and the hard surface vacuum comprises a filling device (60) with an inlet channel (50) having a filling opening (51). Beneath the filling opening (51), the waste liquid tank comprises a collecting chamber (55) for separated liquid, and the filling channel is surrounded by an alternative chamber (56) of the waste liquid tank (25), said chamber receiving liquid from the collecting chamber when pivoting the hard surface vacuum from the vertical position.

Description

technical field [0001] The invention relates to a hard surface suction device having a suction nozzle and a suction unit which is fluidly connected to the suction nozzle via a flow path for sucking a liquid-air mixture from a hard surface , and the hard surface suction apparatus has a separating device for separating liquid from the liquid-air mixture and a dirty liquid tank for containing the separated liquid. Background technique [0002] Such a hard surface suction device can be used for suctioning hard surfaces, in particular tiled walls or floors, or also for removing water films from window panes or glass doors. For this purpose, a suction air flow can be generated by means of the suction unit, so that dirt particles and water droplets can be sucked up from hard surfaces by the suction nozzle and transferred into the dirty liquid container. Such hard surface suction devices are disclosed, for example, from US patent documents 3,254,360 and 3,118,165. Furthermore, suc...
