Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automatic building cleaner for cleaning an outer wall surface of a building such as a building.

[Prior Art] FIGS. 5 and 6 show an automatic building cleaner having almost the same function as the conventional apparatus disclosed in Japanese Patent Publication No. 60-24280, for example.

In the figure, (1) a building, (2) a surface to be cleaned made of window glass of the building (1), (3) a roof car having a hoisting machine (not shown) disposed on the roof of the building (1), (4) is a moving body suspended on a wire rope (3a) pulled out from a hoist of a roof car (3), and (5) is provided on the moving body (4) to clean a surface to be cleaned (2). With a cleaning tool, a belt wheel (5A) (5B) rotated by a motor (not shown) and an endless belt (5d) wrapped around the belt wheel (5A) (5B) and having a brush (5C) It is composed of (5e)
Is an extruding device for moving the cleaning tool (5) forward and backward in the direction of the surface to be cleaned (2). (6) is a water tank provided on the bottom side of the moving body (4) to store cleaning water (7) for cleaning the surface to be cleaned (2), and (8) is driven by a motor (9) to wash water (7). ) Is a water supply pump for pumping water, and (10) is an electromagnetic wave provided in a pipe (12) for spraying washing water (7) pumped by a water supply pump (8) from a nozzle (11) to an upper part of a cleaning tool (5). The valve (13) is provided on the moving body (4) and is made of an elastic material such as rubber for recovering the washing water (7) from the surface to be cleaned (2) to the water tank (6) via the pipe (14). It is a drainer. The configuration of the water supply pump (8), the solenoid valve (10), the nozzle (11), and the pipe (12) is referred to as a water supply system for the wash water (7).

Next, the operation of the conventional automatic cleaning device will be described.
First, the moving body (4) is suspended by the wire rope (3a) unwound from the hoisting machine of the roof car (3), and descends and stops facing the surface (2) to be cleaned. Next, the cleaning tool (5) is pressed against the surface to be cleaned (2) by the pushing device (5e). Subsequently, the water supply pump (8) is driven by the motor (9), and when the solenoid valve (10) is opened, the washing water (7) stored in the water tank (6) is supplied from the water tank (6) to the water supply pump (8). →
Water is sprayed from the nozzle (11) to the cleaning tool (5) via the solenoid valve (10). At this time, the cleaning tool (5) is driven by a motor (not shown).
And starts rotating in the direction of the arrow shown in FIG. Then, the cleaning water (7) moves from the cleaning tool (5) to the surface to be cleaned (2) and adheres to the surface to be cleaned (2) by the brush (5C) rubbing the surface to be cleaned (2). The dirt is removed and the surface to be cleaned (2) is cleaned. Thereafter, the washing water (7) used for washing the surface to be cleaned (2) is drained by a drain plate (13) in contact with a lower portion of the surface to be cleaned (2).
It is guided to 4), removed from the surface to be cleaned (2), and collected in the water tank (6). The washing water (7) thus collected is pumped up again by the water supply pump (8) and circulates in the above-mentioned path. When the cleaning water (7) is repeatedly used for cleaning the surface to be cleaned (2), the cleaning water (7) gradually contains dirt, ie, dust, on the surface to be cleaned (2). Every few hours, it is replaced with fresh washing water (7). The reason why the cleaning water (7) is circulated for a certain period of time and reused is that the cleaning water (7) is used only once for cleaning the surface to be cleaned (2) and is disposable.
This is because a large amount of the cleaning water (7) is required, and it is difficult to reduce the weight of the moving body (4) on which the cleaning water (7) is loaded. That is, if the weight of the moving body (4) cannot be reduced, the size of the roof car (3) suspending the moving body (4) increases and the weight increases. Expensive. Therefore, it is extremely important to reuse the washing water (7) to reduce the weight of the moving body (4).

In addition, there is a conventional automatic cleaning machine for a building as shown in FIG. Although the detailed description is omitted, the sixth
The structure of the cleaning tool (5) is different from the conventional example shown in the figure.

[Problem to be Solved by the Invention] In the automatic building cleaning machine configured as described above,
Cleaning water (7) for cleaning the cleaning surface (2) of the building (1)
However, the water tank (6) → water supply pump (8) → solenoid valve (10) → nozzle (11) → cleaning tool (5) → surface to be cleaned (2) → draining board (13) → water tank (6) Since the cleaning water (7) is circulated for a certain period of time, the cleaning water (7) contains dirt removed from the surface to be cleaned (2), that is, dust and the like. ) Causes wear of the bearing seal (not shown), causing water leakage from the bearing portion (not shown).

Dust and the like contained in the washing water (7) are removed from the solenoid valve (10).
In addition, the nozzle (11) is clogged, so that the cleaning water (7) is not sprayed on the cleaning tool (5).
If the cleaning water (7) is not sprinkled on the cleaning tool (5), the surface to be cleaned (2) cannot be cleaned, and if the surface to be cleaned (2) is heat ray reflective glass, there is no cleaning water (7). Since the brush (5C) of the cleaning tool (5) rubs the glass surface, there is a problem that the heat ray reflective coating on the glass surface is damaged.

The present invention has been made to solve such a problem, and even if the cleaning water containing the dust and the like after cleaning the surface to be cleaned is pumped out of the water tank and reused, the cleaning water supply system may fail. There is no building intended to provide automatic cleaning machines.
