Abstract

The invention relates to a liquid suction device (1), which has a suction head (2), a sewage storage tank (5) and a suction fan (6). The suction head (2) has two lips (3) A delimited suction slit (4), wherein the suction slit (4), the sewage tank (5) and the suction fan (6) are connected to each other by means of a suction channel (7) so that liquid can be removed from the surface to be cleaned It is sucked into the sewage storage tank (5) through the suction gap (4). In order to provide a liquid suction device (1) which does not leave liquid traces on the surface, it is proposed to provide an air channel (8) on one side with the pressure side of the fan, in particular with the suction fan (6 ) is connected to the pressure side facing away from the suction channel (7) and to the suction slit (4) on the other side, so that the blast generated by the fan, in particular the suction fan (6), can be conveyed to the suction inside seam (4). Furthermore, the invention relates to a wet cleaning device (13) having such a liquid suction device (1) and to a method for sucking liquid from a surface to be cleaned by means of such a liquid suction device (1).

Description

technical field

[0001] The invention relates to a liquid suction device, in particular for suctioning liquids from hard floor surfaces and / or window surfaces, said liquid suction device having a suction head, a sewage storage tank and a suction fan, said suction The head has a suction slit delimited by two lips, wherein the suction slit, the sewage tank and the suction fan are interconnected by means of a suction channel so that liquid can pass through the suction slit from the surface to be cleaned is sucked into the sewage storage tank. Background technique

[0002] Liquid suction devices of this type are known in the prior art. The liquid suction device is usually used in combination with cleaning elements in wet cleaning devices, which first apply liquid to the surface to be cleaned by means of a liquid application device, treat the surface by means of the cleaning element and then apply the liquid by means of the liquid suction device Excess liquid is sucked away from...

Embodiment Construction

[0022] A wet cleaning device 13 is shown, designed here as a hand-held guided wet cleaning device, which has a liquid suction device 1 as well as a cleaning element 14 and a liquid application device 15 . The cleaning element 14 and the liquid application device 15 are designed as a common surface installation with a liquid reservoir. On the side facing the surface to be cleaned, the liquid tank has a cleaning element 14 , designed here as a cleaning cloth. The liquid application device 15 and the cleaning element 14 are connected to each other through the perforations of the wall of the liquid application device 15 in such a way that the liquid is continuously supplied from the storage tank of the liquid application device 15 to the cleaning element 14 and is thus applied to the surface to be cleaned. in the cleaning process.

[0023] The liquid suction device 1 of the wet cleaning device 13 has a suction head 2 which is designed here as a flat, double-walled part between wh...
