Description

[Detailed description of the invention] The present invention relates to a car washing device for an automobile body.

There already exists a device that includes a spray nozzle at the tip of a pipe and sprays water onto the vehicle body from the nozzle to clean the vehicle body. However, washing a car body requires a considerable amount of water, and conventionally all the water after car washing is thrown away, resulting in high costs.

Therefore, a purification system has been proposed in which a wastewater treatment device is installed to purify and reuse the wastewater after car washing, as seen in, for example, Japanese Patent Application Laid-Open No. 56-51276. As a means for collecting wastewater, a recovery path is provided on the ground, and the wastewater treatment device is also fixedly provided with an oil-water separation tank adjacent to the recovery path, a water storage tank adjacent to this oil-water separation tank, etc. There is.

For this reason, the car washing area is limited to the area where the collection path is formed, and only the washing water used for car washing here is collected in the wastewater treatment equipment. If a car cannot be washed at that location, there is a risk that the device will not be used effectively.

The purpose of the present invention is to eliminate the disadvantages of the conventional example, eliminate wasteful consumption of water resources with a simple and inexpensive product, reduce running costs, and maximize the effectiveness of the device without restricting the car washing position. The purpose is to provide a car wash device that can be used.

However, according to the present invention, the purpose of the lever is to provide a car washing device for washing the body of an automobile using jetted water, which has casters on the lower surface and includes a water suction means, a recovered water filtration means, and a washing water sending means. A movable water treatment device is provided, an injection nozzle is communicated with the washing water sending means via a pipe, a handle valve and a hose, and a water recovery pipe is communicated with the water suction means via a handle valve and a hose. , the above-mentioned handle-cum-valve is achieved by comprising a water valve and a return valve.

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

If you hold the handle 4 and the handle valve 5 with your hands and press the close contact part 9 of the cover body 8 against the surface of the vehicle body to open the water 6, the water will be stored in the cleaning water delivery chamber 17 and will be released into the heater 2.
The water heated in step 5 is pumped through hose 1 by pump 24.
2 and is sprayed from the nozzle 3 through the pipe 2 to wash the car body 31 of the automobile.

On the other hand, the inside of the vacuum chamber 15 is evacuated by the pump 18 and has a low pressure, and if the return valve 7 is opened, the water accumulated at the bottom of the cover body 8 after cleaning is returned to the vacuum chamber via the water recovery pipe 10 and the hose 13. 15. The water thus stored in the vacuum chamber 15 is moved to the filtration chamber 16 via the water pipe 20 by the pump 19, passes through the filter 21, and dirt is removed there.

The water accumulated in the lower part of the filtration chamber 16 is transferred to the washing water delivery chamber 17 through the water pipe 22, and the same circulation is performed thereafter, so the car wash can be continued while sequentially moving the positions of the nozzle 3 and the cover body 8. .

Since the water treatment device 11 can be freely moved via the casters 14, the car wash can be carried out by stopping at any location, and the water used after the car wash can be completely recovered no matter where the car is washed.
