Embodiment Construction

[0029] The drawing schematically shows a portable hard surface suction device 10 with which liquids can be sucked from hard surfaces, such as window panes. In this case, the hard-surface suction device 10 can be grasped by the user's hand on the handle 12 and guided along the hard surface on the hard surface in accordance with a conventional type of wiper with a rubber lip.

[0030] The hard-surface suction device 10 comprises a basic housing 14 which forms the handle 12 and accommodates a suction unit 16 with a suction turbine 17 and an electric motor 18 . Arranged within the base housing 14 is at least one rechargeable battery 19 , in particular a lithium-ion battery, for supplying the electric motor 18 with energy. The base housing 14 forms a mounting surface 21 on the underside, so that the hard-surface suction device 10 stands on a positioning surface.

[0031] Next to the side of the basic housing 14 is arranged a dirty liquid tank 23 which can be removed from the basic...

Abstract

The invention relates to a portable hard surface vacuum (10) comprising a suction nozzle (45) and a suction unit (16), which is in fluid connection with the suction nozzle, for vacuuming a liquid-air mixture from a hard surface, and comprising a separating device (40, 57) for separating liquid from the liquid-air mixture and comprising a waste liquid tank (23) for receiving the separated liquid. In order to refine the hard surface vacuum in such a way that a constant suction flow is provided, regardless of the fill level of the waste liquid tank, and such that operation in an arbitrary orientation in relation to the vertical position can be carried out, a separating chamber (33) is arranged between the suction nozzle and the suction unit, said chamber housing the separating unit and being in fluid connection via a suction line (47) to the suction port (48) of the suction nozzle and in fluid connection to the suction unit via a suction line (60), and said chamber being connected via an outlet opening (67) to the waste liquid tank, wherein the port regions (51, 61) of the suction (47) and vacuum line within the separating chamber are surrounded at least partially by intermediate storage regions (71, 72, 73) for separated liquid in the circumferential direction.

Description

technical field [0001] The present invention relates to a portable hard surface suction device having a suction nozzle and a suction unit in flow communication with the suction nozzle for extracting from The hard surface sucks the liquid-air mixture, the separator is used to separate the liquid from the liquid-air mixture, and the dirty liquid tank is used to contain the separated liquid. Background technique [0002] Liquids from hard surfaces such as window panes can be sucked up by means of such a hard surface suction device. For this purpose, a suction flow is generated by means of a suction unit, so that a mixture of liquid and air can be sucked in through the suction nozzle. The liquid can be separated from the mixture of liquid and air by means of a separating device and transferred to the dirty liquid tank. The hard-surface suction device is designed to be portable, so that it can easily be guided manually by the user along the hard surface to be suctioned. [000...
