Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vehicle cleaning device for cleaning 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 may be damaged, and if there is a protrusion on the vehicle body such as a side mirror, there is a risk of damage by 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 or risking damage to protrusions, but on the other hand, heavily soiled areas such as around the feet cannot be thoroughly cleaned, resulting in unwashed residue. There were drawbacks.

[Summary of the Invention] The present invention has been made to improve the above-mentioned drawbacks of the prior art, and by adding cleaning with a rotating cleaning body made of a soft material to cleaning with a high-pressure water fountain, it is possible to avoid scratches on the painted surface. This realizes cleaning without leaving any residue.

The rotary cleaning body in the present invention is made of a soft material such as felt, and does not damage painted surfaces as compared to brushes and the like.

Although the cleaning power is lower than that of brushes, etc., most of the dirt is removed by cleaning with high-pressure water, so this rotating cleaning body does not require much cleaning power. The rotary cleaning body may be installed at any location as required, such as at a location where the area around the feet, which is heavily soiled, is to be cleaned.

According to the above configuration, neither cleaning with a high-pressure water fountain nor cleaning with a rotary cleaning body made of a soft material will damage the paint film. Moreover, since the rotating cleaning body can clean areas that cannot be cleaned with high-pressure water, the overall cleaning power is not inferior to that of conventional brush types.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a plan view, FIG. 2 is a side view of the left frame as seen from the inside, and FIG. 3 is a side view of the right frame as seen from the inside.

The gate-shaped frame X runs on the running rail Y in the direction of the arrow,
Washing is performed by straddling the vehicle Z located between the rails Y.

A top high-pressure water fountain pipe 10 is disposed in the width direction on the ceiling at the center of the frame X in the running direction. This fountain pipe 10 is provided with a plurality of downwardly directed fountain nozzles. In addition, a side blower nozzle 51 (described later) is vertically provided on both side walls at the center of the frame It is designed to spray water. The top high-pressure water fountain pipe 10 is also attached to a top blower nozzle 50, which will be described later, and is movable in the vertical direction together with the nozzle in response to irregularities on the upper part of the vehicle.

The high-pressure water fountain pipe 10.11 is connected to a water tank 12 and a high-pressure pump 13 mounted on the left side wall of the frame X, and these constitute the high-pressure fluid injection device 1. A water hose 120 is connected to the water tank 12, and water is constantly supplied through a pole tap until it is full.

A pair of rotary cleaning bodies 2 are mounted below both rear side walls of the frame X. The rotary cleaning body 2 is mounted so as to be rotatable in the horizontal direction, and is configured to be able to extend in the width direction of the frame X. Details of this cleaning body 2 are shown in FIG. The cleaning body 2 is composed of a rotating membrane 20 and a soft material 21 attached around the rotating membrane 20.

The soft material 21 may be made of a material that does not damage the vehicle paint film, such as felt, flannel, or chamois leather. A large number of slits are formed in the soft material 21 to form a strip shape, and a plurality of slits are attached to the rotating membrane 20 at appropriate intervals in the circumferential direction. Such a soft material 21 does not damage the paint film of the vehicle Z unlike a brush.

The rotary cleaning body 2 may be installed in a heavily soiled area if necessary, but in this embodiment, it is located below both side walls in order to clean the area around the legs of the vehicle Z.

Note that the rotating cleaning body 2 is rotated by an air cylinder, and the rotating membrane is rotated by a motor.

A detergent jetting pipe 3 is disposed around the rear entrance of the gate-shaped frame X, and is configured to jet detergent from a detergent tank 30 housed in a side wall of the frame toward the vehicle.

The tank 30 is equipped with a pump 31 and an agitator 32.
is provided to prevent detergent from settling.

In this embodiment, a wipe curtain 4 made of a soft material is attached to the front surface of the frame 1 in the direction of movement. This curtain 4 was proposed by the applicant in Japanese Patent Application No. 59-6295, and is designed to wash a vehicle by coming into contact with the vehicle. Also, like the rotary cleaning body 2, the material is made of felt, etc., which does not damage the painted surface.

The curtain 4 is divided into two pieces in the width direction, and each curtain 4.4
is suspended from a frame 40.40 that can be rotated toward the side wall and can be stored toward the side wall. The frame 40 is provided with a swinging mechanism (not shown) to swing the curtain 4 and improve the cleaning effect.

A gate-shaped water injection pipe 41 is provided on the front side of the curtain 4, and a pump 1 attached to the water tank 12 is connected to the water tank 12.
The water supply receiver 21 is configured to inject water into the vehicle Z. Furthermore, water inlet pipes 42 are provided in the center of the frame in the vertical direction on both side walls, and similarly receive water from the tank 12.

As described above, the blower nozzle 5 is attached to the center of the frame X in the running direction. This nozzle 5 consists of a top blow nozzle 50 provided on the ceiling and side blow nozzles 51 provided on both sides.

Each of the blower nozzles 50, 51 moves forward and backward according to the height and width of the vehicle. These blow nozzles 50.51
are connected to blowers 52 provided on both side walls via flexible ducts to receive air.

In addition, 6 is a near compressor housed in the side wall, and 60 is its air receiver. The compressor 6 is a pressure switch type, and when the pressure of the receiver 60 decreases, it automatically operates, and when the pressure reaches a certain level, it automatically switches off. The system is automatically shut down and is always ready to supply the necessary air. This air is supplied to the air cylinder and nozzle 50 for rotating the rotary cleaning body 2 described above.
It is used as a power source for an air cylinder for moving the wipe curtain 51 up and down and opening and closing the wipe curtain 4.

Further, the rotation of the near compressor 6, high pressure pump 13, pump 31, agitator 32, or rotary cleaning body 2 is driven by an electric motor, and a control panel 7 provided in the frame
and is connected to a power source via a cabtyre cord 70.

In this embodiment, the traveling mechanism of the gate-shaped frame X and the waxing device are the same as those of the conventional ones, so explanations and illustrations thereof will be omitted.

Further, in this embodiment, as explained above, the water tank 12, high-pressure pump 13, detergent tank 30, near compressor 6, etc. are all mounted inside the gate-shaped frame X. This is because in conventional devices, these pumps and tanks were located outside the frame, which was disadvantageous in terms of space at car washes.Also, the number of hoses, etc. increased, and the load was placed on one side of the circular frame It has some disadvantages such as being unfavorable, and this was designed to improve this disadvantage. With this configuration of this embodiment, only the water hose 120 and the cabtire cord 70 are led out of the system from the frame X, so that the frame X can run smoothly. Furthermore, since there is no need for space around the frame X to install a tank, pump, etc., there is an advantage that it can be installed in a narrow place.

Next, the operation will be explained.
(This cleaning device performs cleaning by moving the gate-shaped frame X back and forth twice.

On the first outbound trip, water is injected from the water injection pipes 41 and 42, the wipe curtain 4 is extended and swung, and the rotary cleaning body 2 is driven to perform preliminary cleaning of the vehicle. And at the same time detergent spout pipe 3
Spray detergent onto the vehicle.

On the first return trip, the wipe curtain 4 and the rotating cleaning body 2 are stored, water injection is also stopped, and nothing is done to the vehicle.

The chemical action of the detergent on this dirt lifts dirt from the surface of the vehicle.

On the second outbound trip, high-pressure water is sprayed to remove dirt while the high-pressure water fountain pipes io and 1i follow the surface of the vehicle. At this time, the rotary cleaning body 2 may be driven simultaneously. On the second return trip, the blower 52 is driven to blow air from the nozzles 50 and 51 to dry the vehicle 2 and complete the cleaning.

In addition to the above-mentioned cleaning method, it is also possible to adopt various cleaning patterns, such as opening the wipe curtain 4 half-open and swinging it.

[Effects of the Invention] As explained above, since the vehicle cleaning device of the present invention is equipped with a rotary cleaning body made of a soft material in addition to a high-pressure fluid injection device, it has a high cleaning ability and does not leave any residue after washing, and can clean the vehicle easily. It has the effect of not damaging the painted surface.
