DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car washing water draining device for washing large vehicles such as buses, electric trains, trains, and streetcars, and then draining the car washing water attached to the vehicle body.

[0002]

2. Description of the Related Art Conventionally, in the case of a large vehicle such as a bus, a train, a train, a tram, etc., the vehicle itself is large.
It is air-dried, and car washing water is not actively drained. For this reason, stains or stripes may be attached to the window glass or the vehicle body. These stains and stripes are caused by silica, calcium, sodium chloride, etc. contained in the wash water such as well water, which cause damage to the aesthetic appearance and the transparency of the window glass. Such problems have become apparent. Recycling such car wash water becomes even more noticeable.

[0003] In the case of a passenger car, the car washer is equipped with a blower for blowing air for drying to remove car wash water from the car body. Such a problem hardly occurs. However, the air blowing nozzle for drying in the conventional car washer mainly includes a side nozzle that removes car wash water on the side of the vehicle body and a top nozzle that removes car wash water on the upper surface of the vehicle body. It is provided vertically when viewed from the side, and the top nozzle is arranged in a horizontal line so as to cross the vehicle body when viewed from above (Japanese Patent No. 2696).
No. 601).

Therefore, there may be no problem in the case of a relatively small vehicle such as a passenger car, but when it is used as a draining device for a large vehicle such as a bus, a train, a train, a tram, etc. Problems arise. For example, the roof of a bus not only has an area several times to several tens of times that of a passenger car, but also is almost flat, so that a horizontal linear top nozzle moves from the front of the vehicle body toward the rear of the vehicle body. Since the amount of water gradually increases as the car wash water collects, a portion of the car wash water may remain on the roof without being removed.

[0005] On the other hand, when the vertical side nozzle moves from the front of the vehicle body to the rear of the vehicle body, the car wash water attached to the side of the vehicle body collectively flows down like a waterfall.
Some of the car wash water may remain on the side of the vehicle without being removed. In particular, when the top nozzle and the side nozzle have the same phase, the car wash water on the roof merges with the car wash water on the side of the vehicle body, so that a portion of the car wash water often remains on the side of the vehicle body.

Therefore, it is conceivable to completely remove the car wash water by greatly increasing the air pressure of the drying air. In that case, however, another problem that equipment costs for a compressor, piping, and the like are significantly increased. Newly occurs. On the other hand, there is a patent publication describing that the side nozzle is inclined forward and downward (see Japanese Patent No. 2557275).

[0007] However, if the inclination angle of the side nozzle is set to a large value, car wash water may flow down like a single waterfall. Conversely, if the inclination angle of the side nozzle is reduced, the length of the side nozzle may be reduced. Becomes long and uneconomical.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and an object of the present invention is to apply an air pressure equivalent to that of a conventional draining device while using a bus, An object of the present invention is to provide a car wash water draining device that can quickly and reliably drain car wash water from a large vehicle such as a train, a train, or a tram.
