CONSTITUTION:When a car is washed by a rotary washing body, the operation of a high pressure pump 12 is stopped by a control unit 2 in advance, and the car X is situated between rails 51. Then, an air compressor 33 is operated by another control unit 34, rotating brushes 30 and 32, and simultaneously water is poured out of an injection pipe 63, thus the car is washed clean. Likewise, when the car washing by means of a high pressure water jet is carried out, the air compressor is controlled by the control unit 34, while these brushes 30 and 32 and an emitter 31 are all housed. Afterward, a rear frame is traveled, and a detergent is sprayed to the car as the injection pipe 63 is pouring water at an outward path. And, at a return path, the high pressure pump 12 is driven, spouting high pressure water out of a high pressure water-jet pipe 10, whereby smudges are washed away together with the detergent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle washing device for washing vehicles such as automobiles.

[Prior Art] A vehicle cleaning device usually has a configuration in which a brush is rotated, water is sprayed onto the vehicle, and the brush is brought into contact with the vehicle body to clean the vehicle.

However, cleaning with such a rotating brush has the disadvantage that the painted surface of the vehicle body is scratched. Furthermore, if there is a protrusion such as a side mirror on the vehicle body, there is a risk of damage from the rotating brush.

In order to improve these drawbacks, vehicles with a configuration in which high-pressure water is sprayed onto the vehicle for cleaning have become popular in recent years. This configuration has the advantage of not damaging the painted surface and eliminating the risk of damaging protrusions, but on the other hand, heavily soiled areas such as around the feet cannot be thoroughly cleaned, resulting in residue. There were drawbacks.

[Summary of the Invention] The present invention has been made to improve the drawbacks of the prior art described above, and is configured so that cleaning with a high-pressure water fountain and contact cleaning with a rotating cleaning body such as a brush can be performed selectively or simultaneously. It is.

The apparatus of the present invention includes a high-pressure fluid injection device and a rotary cleaning body. A high-pressure fluid injection device injects a cleaning fluid such as water at high pressure toward a vehicle to be cleaned, and the vehicle is cleaned by this fluid injection. The high-pressure fluid injection device has an It that controls its operation.
, II control device is provided, and the injection can be turned on and off at least as required.

The rotary cleaning body cleans the vehicle while rotating, and usually uses a rotating brush or the like. A mechanism is provided for making the rotary cleaning body contact or non-contact with the vehicle, so that execution and stopping of cleaning by the rotary cleaning body can be controlled as necessary.

In the above configuration, by operating the high-pressure fluid injection device by the control device and making the rotating cleaning body non-contact with the vehicle, cleaning can be performed only by high-pressure fluid injection, and cleaning can be performed without damaging the painted surface. Furthermore, if the high-pressure fluid injection device is stopped by the control device and the rotating cleaning body is brought into contact with the vehicle, cleaning can be performed using only the rotating cleaning body, and cleaning without leaving any dirt can be realized. In general, high-pressure fluid jetting and cleaning using a rotating cleaning body may be performed simultaneously, or high-pressure fluid jetting and cleaning using a part of the rotating cleaning body may be performed.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a plan view, FIG. 2 is a front view, and FIG. 3 is a side view.

Reference numeral 50 denotes a gate-shaped frame, which runs on traveling rails 51. A gate-shaped high-pressure water fountain pipe 1 is installed at the rear opening of the gate-shaped frame 50.
0 is attached. The fountain pipe 10 is provided with a plurality of fountain nozzles (not shown) and is configured to spray high-pressure water toward the inside of the circular frame 50, that is, toward the vehicle X to be washed. The fountain pipe 10 is a flexible hose 11
connected to the high pressure pump 12 and water tank 13 via
It is supplied with high pressure water. The fountain pipe 1
0, a flexible hose 11, a high-pressure pump 12, and a water tank 13 form a high-pressure fluid injection device W11.

A control device 2 is connected to the high-pressure pump 12, and controls the drive of the high-pressure pump 12, turning on and off the high-pressure water jet from the fountain pipe 10, and controlling the jet pressure.

Inside the high-pressure water fountain pipe 10, a detergent ejection pipe 60 of almost the same type as this is installed in parallel, and a detergent tank 6 equipped with a pump.
1 through a hose 62, and sprays the detergent toward the center of the frame 50.

On both sides of the frame 50, a pair of all-around brushes 30.30 are attached as the rotary cleaning body 3 on the rear side in the running direction, and a pair of mitter 31.31 is attached at the center. Further, one top brush 32 is mounted approximately in the center of the ceiling portion of the frame 50. all around brush 3
As shown in FIG. 2, the 0.30 is vertically supported and is designed to come into rotational contact with the side of the vehicle for cleaning. As shown in FIG. 2, the mitter 31.31 is attached to the lower part of the side wall of the frame 50 with its lower end inclined toward the inside of the frame, and is adapted to wash the area around the legs of the vehicle. The brush 30 and the mitter 31 are mounted on the side wall of the frame so as to be rotatable in the horizontal direction, and can be moved forward and backward in the width direction of the frame. Although various devices can be used as a driving device for this rotation, an air cylinder is used in this embodiment.

Further, an air motor is used to rotate the brush 30 and the mitter 31.

As shown in FIG. 3, the top brush 32 is pivotally supported at approximately the center of the side wall in the vertical direction and is mounted so as to be rotatable in the vertical direction, and is adapted to clean the front, rear, and upper surfaces of the vehicle. The rotation of the top brush 32 is also configured to be performed by an air cylinder, and the rotation is also configured to be performed by an air motor.

Each of the air cylinders and the air motor are connected to the near compressor 33 and are controlled by a control device W134. In this embodiment, the air cylinder and air motor of the mitter 31 can be driven independently.
Only 1 can be operated. Since the mitter 31 is used to clean the area around the feet which is heavily soiled, only the mitter 31 is operated during high-pressure fountain car washing to increase the cleaning effect around the feet. Here, the term "mitter" refers to a rotary body equipped with a soft material such as felt, and has the advantage of being less likely to scratch the coating surface compared to conventional brushes and the like.

A water injection pipe 63 is further attached to the front entrance of the gate-shaped frame 50, and is connected to the water tank 13 and the attached pump 13- via a hose 64, so as to inject water into the vehicle. .

In the above embodiment, a vehicle drying device is also provided, but since this configuration is the same as that of a conventional device, explanation and illustration thereof will be omitted. Furthermore, explanations and illustrations of the traveling mechanism of the gate-shaped frame 50 will be omitted for the same reason.

Next, the operation will be explained.

In the case of cleaning with a rotary cleaning body, the operation of the high pressure pump 12 is stopped by the 1tlJ control device 2. When the vehicle X is positioned between the running rails 51, the near compressor 33 is driven by the control device 34, and the brushes 30, 32 and the mitter 31 are rotated to project toward the center of the frame and rotated at the same time. Then, while injecting water from the water injection pipe 63, the frame 50 is run in the direction of the arrow, and the brush 30.3 is
2 and the mitter 31 are brought into rotational contact with the vehicle X and cleaned. After the frame 50 has passed the vehicle X and finished cleaning, the frame 50 is moved backwards and returned to its original position. At this time, brush 3
0.32 and Mitter 31 are stored so that they do not contact vehicle X,
Operate the drying equipment to dry the vehicle.

When performing a high-pressure fountain car wash, the near compressor 33 is controlled by the control device 34, the brushes 30, 32 and the mitter 31 are stored, and their rotation is stopped.

Then, the frame 50 is run, water is poured into the vehicle X from the water injection pipe 63, and detergent is sprayed onto the vehicle X from the detergent spouting pipe 60. At this time, if the area around the feet is very dirty, use Mitta 3.
1 may be operated to wash the area around the feet. Also, when other areas are heavily soiled, the brushes 30 and 32 may be operated. Then, the frame 50 is moved backwards and returned to its original position. On this return journey, nothing is done to the vehicle X, and the dirt on the vehicle is brought to the surface using this first method.

Then, on the second outbound trip, the high-pressure pump 12 is driven, and high-pressure water is jetted out from the high-pressure fountain pipe 10 to wash away dirt and detergent. Further, at this time, the water around the feet may be washed by driving the mitter 31 while injecting water from the water injection pipe 63. Also brush 30
．． 32 may be driven as in the first outgoing trip.

After cleaning is completed, the frame 50 is moved backwards and returned to its original position. At this time, the vehicle is dried using a drying device.
