2. Description of the Related Art Conventionally, since the cleaning of the wall surface of a building is performed in a wide area and at a high place, it is inefficient to perform manual work such as window cleaning. A cleaning method (hereinafter, abbreviated as “jet injection method”) has been performed in which (jet water) is sprayed to remove and remove dirt.

However, in such a jet injection method, it is difficult to completely remove the dirt and some dirt remains, so that most of them require individual manual work after the whole work, and as a result, it is very difficult. The work efficiency was poor, and the sprayed water hit the wall surface and was scattered, and in high-altitude work, the sewage splashed over a wide area in the vicinity, causing troubles and complaints in the neighborhood. Since the dirt is removed only by the force, there are many problems such as a large amount of water inevitably being required, which is against the effective use of resources.

By the way, it is difficult to completely remove the adhered dirt even if a considerable amount of high-pressure jet is jetted, but it is easy to remove the dirt by slightly rubbing the part from a high-pressure car wash machine of a vehicle. Can also be learned empirically. Therefore, the inventor of the present application paid attention to this fact, and the same applies to the wall surface of the building. Therefore, the inventor of the present invention has developed the present invention after earnest research. The purpose of this is to provide a useful cleaning and cleaning device for the wall surface of a building, which not only does the cleaning of the wall efficiently by using the cleaning water spray and the brushing but also prevents the scattering of the cleaning water and does not harm the environment. It is a thing.

It is preferable to dispose at least three places so that can be kept parallel to the wall surface 8.

[0018]

Operation of the Embodiment With the above-mentioned configuration, this embodiment operates as follows. The housing 1 is suspended and held by a wire 20 as shown in FIG. 4, and is moved up and down along the wall surface 8 in parallel by the operation of a winch (not shown) (arrow a).

To clean and clean the wall surface of the building, first, the apparatus 1 of the present application is installed on the uppermost part of the wall surface of the building, water is supplied to the jetting means 5, and the motor 31 is driven to rotate the brush body 3. Since the contact amount of the flocking tip group 30e of the brush body 3 with the wall surface 8 is preset by the adjuster means 7, the wet wall surface 8 is rubbed. As a result, dirt that has adhered to the wall surface 8 for many years is scraped off by the cleaning water jetting and brushing, and is even more cleanly washed away by the cleaning water flowing along the wall surface 8 from above.

At this time, the splashes scattered by the brushing are mainly blocked by the splash blocking pieces 4 arranged above and below,
There is no scattering outside. Further, since the rotating shaft of the brush body 3 is horizontal, most of the splashes are scattered in the vertical direction, but some of them are scattered in the horizontal direction. These are prevented from scattering by the shield curtains 6 arranged at the both end edges 21s of the opening 21. In this way, splashes splashing to the outside are almost completely prevented.

While continuing this work, the cleaning / cleaning apparatus 1
Is for lowering at a predetermined speed to sequentially wash and clean the wall surface 8. When the upper and lower wall surfaces have been washed and cleaned, the wall surface 8 is moved to the adjacent surface by the width of the opening, and the above work is repeated again to wash and clean the entire wall surface 8 of the building.

Next, on the wall surface 8, a projection 9 such as a frame of a window frame is provided.
Is often present. When the projection block 9 comes into contact with the projection 9, as shown in the enlarged view of FIG. 4, the droplet blocking piece 4 includes a rubber plate 41 flexibly attached to the outside and a tip portion 41 thereof.
By the function of the bending of e, the hinge 40 bends so as to escape to the outside, and after passing through the protrusion 9, the leaf spring 43 urges it against the wall surface 8 again.

[Other Embodiments] Next, in addition to the brush body 3 used in the above embodiment, a brushing mechanism 10 as shown in a perspective view in FIG.
May be arranged in the opening 21 of the housing 2.
That is, four disks 11, 11, ... With the axis of rotation perpendicular to the wall surface 8 are arranged in the opening 21, and the flocking groups 12, at least in a pair of diagonal positions, on the surface of the disk 11.
The brush bodies 13 are formed by applying the steps 12, ..., And the motors 14 are separately connected to the brush bodies 13 so as to be rotationally driven. In addition, the rotation directions of the adjacent brush bodies 13 are set to different directions. This is for stabilizing the housing 2.

[0024]

[Effect] Since the present invention is configured as described above,
The following effects are achieved. Since the brushing is performed together with the spraying of the cleaning water, a small amount of cleaning water can reliably and efficiently remove the attached dirt.

Further, since the splash block and the screen are provided, it is possible to effectively prevent the splash of sewage due to brushing. Further, since high pressure jet water is not used, a compressor for producing high pressure water and a large amount of water are not required, which can contribute to resource saving and economic efficiency.
