【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the nozzle structure of the adhering water suction device according to claim 1 of the present invention, and FIG. 4 is also referred to in the following description.

As shown in the drawing, a brush 15 formed by bundling linear materials 15 a such as various kinds of animal hair, vegetable fiber, whale beard, synthetic resin fiber, etc. is fitted into the suction port 7 of the nozzle body 8 and attached. The air 14 can be sucked from the back surface of the brush 15 (that is, the upper side of the brush 15 in the drawing) through the gap between the linear members 15a forming the brush 15.

Then, when the brush 15 sweeps the floor surface 11 that has been washed with water while driving the vacuum fan 4, the water 12 on the floor surface 11 moves from the floor surface 11 to the brush 15 due to a capillary phenomenon, and then, It is separated from the brush 15 by the air 14 flowing through the gap between the linear members 15a and is sucked into the cyclone separator 3 via the hose 2.

Therefore, according to the above-described embodiment, even if the floor surface 11 has irregularities, undulations, steps, etc., the brush 15 bends in accordance with the shape of the floor surface 11, and the adhesion to the floor surface 11 of the nozzle body 8 is improved. Since it is maintained over the entire length in the width direction (direction perpendicular to the drawing of FIG. 1), water absorption work can be performed satisfactorily without leaving water absorption residue. Therefore, for example, in the case of water absorption work after washing with container water, even if the floor surface is like a drainage container like a drainage container, the same attached water suction device as in the case of a dry container with a flat floor surface Can be dealt with.

Further, since the water 12 is moved from the floor surface 11 by utilizing the capillarity of the brush 15, even if the floor surface 11 is hydrophilic, the water absorption work can be satisfactorily performed without leaving any residual water. It can be carried out.

Further, since the suction nozzle 1 does not stick to the floor surface 11 as in the conventional case, the force required to move the suction nozzle 1 may change depending on the amount of water adhering to the floor surface 11 and the floor surface shape. There is no need, and it does not require much power.

When the air 14 is sucked through the gap 13 (see FIG. 5) between the spatula 10 and the floor surface 11 as in the conventional case, the gap 13 changes depending on the shape of the floor surface 11 and the vacuum is generated. While the air volume and the air pressure of the fan 4 become unstable, in this embodiment, since the air passage area in the brush 15 is constant regardless of the shape of the floor surface 11, the air volume and the air pressure of the vacuum fan 4 are It is stable, and changes in water absorption performance due to the shape of the floor surface 11 are small.

FIG. 2 shows an embodiment of the nozzle structure of the adhering water suction device according to claim 2 of the present invention. The thin tube 16 is provided at the root of the linear member 15a in the embodiment of FIG. Is sandwiched between them to form a brush 17, and the air 14 is sucked from the back surface of the brush 17 through the thin tube 16.

In this embodiment, since the air passage area in the brush 17 can be reliably ensured by sandwiching the thin tube 16 at the root of the brush 17, the water transferred from the floor surface 11 to the brush 17 due to the capillary phenomenon. The air 12 flowing in the thin tube 16 can be satisfactorily separated from the brush 17 and smoothly passed through the thin tube 16 to be sucked, and the air volume and pressure of the vacuum fan 4 are further stabilized.

FIG. 3 shows an embodiment of the nozzle structure of the attached water suction device according to claim 3 of the present invention, in which a mounting plate 18 is arranged at the suction port 7 of the nozzle body 8 and A large number of flexible thin tubes 19 are planted in the plate 18, and the upper ends of the flexible thin tubes 19 are opened to the upper surface of the mounting plate 18 to form a brush 20. The air 14 can be sucked from the back surface of the brush 20 through the inside of the.

In this embodiment, when the floor surface 11 washed with water is swept with the brush 20 while the vacuum fan 4 is driven, the water 12 on the floor surface 11 is caused by the air 14 flowing inside the flexible thin tube 19. Since water is directly sucked from the lower end of the flexible thin tube 19, the water 12 can be quickly removed from the floor surface 11.

The nozzle structure of the adhering water suction device of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. is there.
