TECHNICAL FIELD The present invention relates to a car wash machine that applies a coating agent to a vehicle to be washed.

A conventional car wash machine installed at a gas station or the like is disclosed in Patent Document 1. This car wash machine has a gate-shaped frame that reciprocates in the longitudinal direction with respect to the vehicle to be washed. A portal frame is provided with a plurality of brushes and a plurality of injection pipes. Each brush slides over the vehicle to be washed to wash the vehicle. The spray pipes spray rinse water, detergent or coating agent toward the vehicle to be washed, respectively.

In the car wash machine configured as described above, when the car wash is started, an outbound process is performed in which the gate-shaped frame moves toward the rear of the vehicle to be washed. While the detergent is injected from the injection pipe, the surface of the vehicle to be washed is washed by the brush. A jet tube trailing the brush jets water and the detergent is washed away. Further, the coating agent is injected from the injection pipe following the water injection pipe, and a film is formed on the surface of the vehicle to be washed by applying the coating agent.

In addition, the return process is performed according to the car wash course, and the coating agent is sprayed from the injection pipe to apply the coating agent again. This makes it possible to form a thick film of the coating agent.

JP 2017-222215 A (pages 6 to 15, FIG. 2)

According to the conventional car wash machine, the injection pipe for injecting the coating agent is provided at one position in the front-rear direction. For this reason, the surface of the vehicle to be cleaned is coated with the coating agent once or twice. However, the front part of the vehicle to be washed, such as the bonnet, is easily damaged by flying stones, insects, etc., and the adhesion of the coating agent is weak. For this reason, a film having a sufficient thickness is not formed, and there is a problem that the coating performance on the front portion of the vehicle to be washed is poor.

On the other hand, by increasing the number of applications of the coating agent, it is possible to form a sufficiently thick film and improve the coating performance. However, when the coating agent is excessively applied to the front window of the vehicle to be cleaned, there is a problem that an oil film is formed on the glass surface of the front window.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a side view and a front view showing a car wash machine 1 of one embodiment. The car wash machine 1 has a car wash machine body 2, a rail 60 and a remote panel 7. - 特許庁The car wash machine main body 2 is formed in a gate shape having two left and right stand portions 2d facing each other and a ceiling portion 2c connecting the upper ends of the stand portions 2d.

A pair of left and right rails 60 are provided on the ground G, and wheels 3 provided on the bottom surface of the stand portion 2 d are arranged on the rails 60 . As a result, the car wash machine main body 2 is erected on the rails 60 and travels on the rails 60 by being driven by a travel motor (not shown) to move in the longitudinal direction with respect to the vehicle 70 to be washed.

The remote panel 7 is arranged along the approach route to the car wash machine main body 2 . The remote panel 7 has a plurality of buttons for setting car wash conditions. In addition, the remote panel 7 can be used to set equipment such as front guard, fender pole, side mirror, rear wiper, roof carrier, and the like.

The shape sensor 9 is composed of a photoelectric sensor, an ultrasonic sensor, or the like, and detects the outer surface shape of the vehicle 70 to be washed entering the car wash machine main body 2 .

The car wash machine main body 2 is provided with a plurality of rotating brushes for sliding and brushing the vehicle 70 to be washed. A rotating brush consists of a top brush 4, a side brush 5 and a rocker brush 6. - 特許庁

The top brush 4 is provided on the ceiling portion 2c so as to be able to move up and down, rotates on a horizontal rotary shaft, and cleans the upper surface of the vehicle 70 to be cleaned. The side brushes 5 are provided on the side of the outlet surface 2b of both stand portions 2d so as to move forward and backward in the left-right direction and rotate on a vertical rotary shaft to wash both side surfaces and the rear surface of the vehicle 70 to be washed. The rocker brushes 6 are provided at the lower portions of both stand portions 2d so as to move forward and backward in the horizontal direction, rotate on a vertical or horizontal rotary shaft, and wash the lower portions of both side surfaces of the vehicle 70 to be washed.

A blower 20 for generating an airflow is arranged on the upper part of the car wash machine main body 2 . The blower 20 is connected to a plurality of air blowing nozzles for blowing air toward the vehicle 70 to be washed. The blower nozzles consist of top blower nozzles 21 and side blower nozzles 22 .

The top air blowing nozzle 21 is provided on the ceiling part 2c so as to be able to move up and down, moves along the upper surface and the rear surface of the vehicle 70 to be washed, and blows air to dry the upper surface and the rear surface. The side air blowing nozzles 22 are provided on both stand portions 2d, respectively, and blow air to dry the side surfaces of the vehicle 70 to be washed.

The stand portion 2d is provided with a tank storage portion 30 for storing a plurality of liquid storage tanks (not shown) storing various liquid agents such as detergents and coating agents. A distribution pipe section 31 is provided above the tank storage section 30 for distributing city water and the liquid agent from each liquid storage tank. Detergent nozzle 11, water nozzles 12, 13 and 15, base nozzle 40, top coat nozzles 41 and 46, and side coat nozzles 42 and 47 are led out to distribution pipe 31 via electromagnetic valves (not shown).

The detergent nozzles 11 are provided at a plurality of locations in the left-right direction of the ceiling portion 2c, and are also provided at both stand portions 2d (not shown). The detergent nozzle 11 is disposed between the inlet surface 2a and the top brush 4, and sprays washing water composed of an aqueous detergent solution to wash the vehicle 70 to be washed. Thereby, the detergent nozzle 11 functions as a washing nozzle for washing the vehicle 70 to be washed.

Water nozzles 12, 13, and 15 are provided at a plurality of locations in the left-right direction of the ceiling portion 2c, and are provided at both stand portions 2d (not shown). A water nozzle 12 is arranged between the detergent nozzle 11 and the inlet face 2a. A water nozzle 13 is arranged between the top brush 4 and the outlet surface 2b. A water nozzle 15 is arranged between the water nozzle 13 and the outlet surface 2b.

The water nozzles 12 , 13 , 15 spray washing water made of city water onto the vehicle 70 to be washed. The water nozzles 12, 13, and 15 wash the vehicle 70 to be washed with water, and also rinse the vehicle 70 with detergent and a coating agent, which will be described later. Thus, the water nozzles 12, 13, 15 function as washing nozzles for washing the vehicle 70 to be washed.

Top coating nozzles 41 and 46 and side coating nozzles 42 and 47 spray an aqueous solution of a coating agent for coating the coated surface of vehicle 70 to be cleaned. A plurality of upper surface coating nozzles 41 and 46 (two each in this embodiment) are provided on the ceiling portion 2c. The upper surface coating nozzles 41 and 46 may be formed to be swingable in the horizontal direction.

The upper surface coat nozzle 41 (first upper surface coat nozzle) is arranged at substantially the same position as the detergent nozzles 11 in the front-rear direction and between the detergent nozzles 11 in the left-right direction. A top coat nozzle 46 (second top coat nozzle) is arranged between the water nozzles 13 and 15 . As a result, the upper surface coating nozzle 41 is arranged on the inlet surface 2a side of the car wash main body 2, and the upper surface coating nozzle 46 is arranged on the outlet surface 2b side.

Moreover, the pitch of the top coat nozzles 41 in the left-right direction is different from the pitch of the top coat nozzles 46 in the left-right direction. In this embodiment, the horizontal pitch of the upper surface coating nozzles 41 is 900 mm, and the horizontal pitch of the upper surface coating nozzles 46 is 600 mm.

Side coating nozzles 42 and 47 are provided on both stand portions 2d. The side surface coat nozzle 42 (first side surface coat nozzle) is arranged at substantially the same position as the top surface coat nozzle 41 in the front-rear direction. The side coat nozzle 47 (second side coat nozzle) is arranged between the top coat nozzle 41 and the top coat nozzle 46 in the front-rear direction. The side coating nozzles 42 and 47 may be formed so as to be vertically swingable.

Further, the upper surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47 inject the coating agent at a high injection pressure (for example, 2 MPa to 3 MPa). The injection angle θ (see FIG. 6) of the upper surface coating nozzles 41 and 46 is set to 25°, for example. The injection angle θ of the side surface coating nozzle 42 is set at, for example, 40°, and the injection angle θ of the side surface coating nozzle 47 is set at, for example, 80°.

Since the vehicle height of the vehicle 70 to be washed differs depending on the type of vehicle, the upper surface coating nozzles 41 and 46 are arranged apart from the vehicle 70 to be washed. Also, the bonnet 70b (see FIG. 8) portion of the vehicle 70 to be washed is further separated from the upper surface coat nozzles 41 and 46. As shown in FIG. Therefore, even if the injection angle θ is small, the coating agent can be dispersed, and the coating agent can be uniformly applied to increase the adsorption force.

On the other hand, since the side surface coating nozzles 42 and 47 are close to the side surface of the vehicle 70 to be washed, the injection angle θ is made larger than that of the top surface coating nozzles 41 and 46 to disperse the coating agent. As a result, the coating agent can be uniformly applied and the adsorption force can be increased.

In addition, the injection pressure of the side surface coating nozzles 42 and 47 is made higher than the injection pressure of the top surface coating nozzles 41 and 46 . As a result, the coating agent sprayed from the side coating nozzles 42 and 47 can collide with the vehicle 70 to be washed and can be dispersed further.

The base nozzles 40 are provided at a plurality of locations in the left-right direction of the ceiling portion 2c, and are provided at both stand portions 2d, although not shown. Further, the base nozzle 40 is arranged between the water nozzle 12 and the top coating nozzle 41, and sprays a base material that forms the base of the coating material. As will be described later in detail, the undercoating agent has a higher adsorptivity to the coated surface than the coating agent and has water repellency.

The coating agents sprayed from the upper surface coating nozzles 41, 46 and the side surface coating nozzles 42, 47 are trimethylsiloxysilicate, nonionic surfactant, and cationic surfactant having a saturated hydrocarbon group with 12 to 18 carbon atoms. consists of an aqueous solution containing Low-temperature stabilizers, emulsion stabilizers, preservatives, pH adjusters, and the like may be added to the coating agent as long as the properties are not impaired. In addition, silicone oil may be added to the coating agent to improve water repellency.

Trimethylsiloxysilicate forms a water-repellent and run-off coating. Nonionic surfactants emulsify trimethylsiloxysilicate. Nonionic surfactants include polyoxyethylene alkyl ethers, polyoxyalkylene alkyl ethers, polyoxyethylene alkylphenyl ethers, polyhydric alcohol fatty acid esters, polyoxyethylene polyhydric alcohol fatty acid esters, polyoxyethylene fatty acid esters, polyglycerin. Fatty acid esters, alkylamine oxides, and the like can be used.

Cationic surfactants increase the adsorption properties of coating agents containing trimethylsiloxysilicate, which have low adsorption properties.

A film of a coating agent containing trimethylsiloxysilicate has water flowability with low sliding friction against water. The amount of water remaining on the vehicle 70 to be washed is reduced because the film of the coating agent has not only water repellency with a large contact angle due to surface tension, but also water flowability.

At this time, if the cationic surfactant has a saturated hydrocarbon group with 12 to 18 carbon atoms, it is possible to suppress the water repellency on the glass surface and form a film having water repellency and water flow on the painted surface. . As a result, water repellency and fluidity are obtained on the coated surface, and water repellency on the glass surface is suppressed.

Cationic surfactants having a saturated hydrocarbon group with 12 to 18 carbon atoms, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, hexadecyltrimethylammonium chloride, octadecyltrimethylammonium chloride, didodecyldimethylammonium chloride, ditetradecyl chloride dimethylammonium, dihexadecyldimethylammonium chloride, dioctadecyldimethylammonium chloride, dodecylamine acetate, dodecylamine hydrochloride, tetradecylamine acetate, tetradecylamine hydrochloride, hexadecylamine acetate, hexadecylamine hydrochloride, Octadecylamine acetate, octadecylamine hydrochloride, and the like can be used.

The primer sprayed from the primer nozzle 40 is composed of an aqueous solution containing amino-modified polysiloxane as a main component and at least one of a nonionic surfactant and a cationic surfactant. A low-temperature stabilizer, an emulsion stabilizer, a preservative, a pH adjuster, and the like may be contained in the undercoat as long as the properties are not impaired.

Amino-modified polysiloxane forms a highly adsorptive, water-repellent film. Nonionic surfactants and cationic surfactants emulsify amino-modified polysiloxanes. As a result, the film of the undercoating agent has water repellency.

As the nonionic surfactant, the same surfactant as the coating agent can be used. As the cationic surfactant, an amine salt type or quaternary ammonium salt type surfactant can be used.

A coating of water-repellent primer reduces residual water on the painted surface. Therefore, the film of the undercoat agent has a binder effect for the coating agent, and the adsorption power of the coating agent can be improved.

In the car wash machine 1 configured as described above, the user drives the vehicle 70 to be washed to stop in front of the remote panel 7 and sets the washing conditions for the vehicle 70 to be washed from within the vehicle 70 to be washed. After setting the car wash conditions, the user moves the vehicle to be washed 70 to a predetermined washing start position.

By operating the remote panel 7, a washing course, a shampoo course, and a coating course can be selected. In the water washing course, the rotating brush is rotated to jet washing water of city water from the water nozzles 12, 13, 15 to wash the vehicle 70 to be washed. In the shampoo course, the rotary brush is rotated to jet washing water containing detergent from the detergent nozzle 11 to wash the vehicle 70 to be washed. At this time, city water is sprayed from the water nozzles 12 and 13 to pre-wash and rinse the vehicle 70 to be washed. In the coating course, the vehicle to be washed 70 is washed in the same manner as the shampoo course, and then the vehicle to be washed 70 is coated with a coating agent.

3 to 9 are side views showing the car washing state of the coating course. When the coating course is selected and the car wash is started, the car wash machine main body 2 moves behind the vehicle 70 to be washed (arrow E1) at a predetermined traveling speed (for example, 5 m/min) as shown in FIG. A first outward process is performed. In the first outbound process, while the shape sensor 9 detects the shape of the vehicle 70 to be washed, each rotating brush rotates to wash the front, rear and top surfaces of the vehicle 70 to be washed.

At this time, washing water S1 containing detergent is jetted from the detergent nozzle 11 preceding the rotating brush. A water nozzle 12 preceding the detergent nozzle 11 sprays the washing water S2 of city water, and water nozzles 13 and 15 following the top brush 4 spray the washing water S2 of city water.

When washing up to the rear surface of the vehicle 70 to be washed is completed, the car wash machine main body 2 is reversed and moved forward of the vehicle 70 to be washed (arrow E2) as shown in FIG. In the first return process, the washing water S2 is jetted from the water nozzle 13 while the rotating brush rotates, and the detergent is rinsed and washed with water.

The cleaning process of the vehicle 70 to be cleaned is completed by the end of the first return process, and the rotating brush is stopped. Next, as shown in FIG. 5, the second outward process is performed in which the car wash machine main body 2 is reversed and moved to the rear of the vehicle 70 to be washed (arrow E1). The second outward process, the second return process, the third outward process, and the third return process form a coating agent applying step of applying a coating agent.

In the second outbound process, the coating agent S4 is sprayed from the upper surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47. As shown in FIG. Further, the base material S3 is sprayed from the base nozzle 40 preceding the upper surface coat nozzle 41, and the washing water S2 of city water is sprayed from the water nozzles 13 and 15. FIG.

The base agent S3 sprayed from the base nozzle 40 is applied to the surface of the vehicle 70 to be cleaned while removing the water film remaining on the vehicle 70 to be cleaned in the cleaning process. At this time, the car wash machine main body 2 moves at a relatively low speed (eg, 5 m/min). Therefore, the water film on the vehicle 70 to be washed can be reliably removed to form the film of the base agent S3.

A coating of the coating agent S4 sprayed from the top coating nozzle 41 and the side coating nozzles 42 and 47 is formed on the coating of the base agent S3. The washing water S2 of city water sprayed from the water nozzles 13 following the upper surface coating nozzle 41 and the side surface coating nozzles 42, 47 performs rinsing to remove excess coating agent S4. This makes it possible to smooth the coating agent S4 and prevent coating unevenness.

Further, the coating agent S4 is overcoated by the upper surface coating nozzle 46 following the water nozzle 13 . Excess coating agent S4 is removed by washing water S2 of city water sprayed from water nozzle 15. FIG.

It should be noted that jetting from the top coating nozzles 46 and the side coating nozzles 47 may be started with a delay from the jetting from the top coating nozzles 41 and the side coating nozzles 42 . The spraying is started after the top coating nozzle 46 and the side coating nozzle 47 move to the positions where the front end of the vehicle 70 to be cleaned is coated, so that the amount of the coating agent can be reduced.

When the top coating nozzle 46 applies the coating agent S4 to the rear end of the vehicle 70 to be washed and the water nozzle 15 is rinsed, the second outward process is completed. Thus, the second forward process forms a forward coating process in which the top surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47 respectively apply the coating agent S4 from the front end to the rear end of the vehicle 70 to be cleaned.

When the second outward process is completed, the second return process is performed in which the car wash machine main body 2 is reversed and moved forward (arrow E2) of the vehicle 70 to be washed as shown in FIG. In the second return process, the coating agent S4 is sprayed from the upper surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47, and the city water washing water S2 is sprayed from the water nozzles 12 and 13.

The coating agent S4 is overcoated by the upper surface coating nozzle 46 . Excessive coating agent S4 is removed by rinsing the water nozzle 13, and the coating agent S4 is further applied by the top surface coating nozzle 41 and the side surface coating nozzles 42, 47. Excess coating agent S4 is then removed by rinsing the water nozzle 12 .

At this time, the jetting of the top coating nozzles 41 and the side coating nozzles 42 may be started with a delay from the jetting of the top coating nozzles 46 and the side coating nozzles 47 . The spraying is started after the top surface coating nozzle 41 and the side surface coating nozzle 42 move to the positions where the coating agent is applied to the rear end of the vehicle 70 to be washed, so that the amount of the coating agent can be reduced.

When the top coat nozzle 41 applies the coating agent S4 to the front end of the vehicle 70 to be washed and the water nozzle 12 is rinsed, the second return process is completed. Thus, the second return process forms a return application process in which the top surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47 apply the coating agent S4 from the rear end to the front end of the vehicle 70 to be washed.

At this time, the car wash machine body 2 moves at a higher speed (for example, 8 m/min) than the second outward process (outward application process). Since the coating agent S4 is applied onto the coating formed in the second outward process, the thickness of the coating can be reliably increased even when the car wash machine main body 2 is moved at high speed. In addition, since the time of the second return process is shortened, the car wash time can be shortened.

After the second return process is completed, the third return process is performed in which the car wash machine main body 2 is reversed and moved to the rear of the vehicle 70 to be washed (arrow E1) as shown in FIG. In the third outward process, the coating agent S4 is sprayed from the upper surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47, and the washing water S2 of city water is sprayed from the water nozzles 12 and 13.

By rinsing the water nozzle 12, the excess coating agent S4 applied in the second return process is removed. The coating agent S4 is overcoated by the top coating nozzle 41 and the side coating nozzle 42 . The excess coating agent S4 is removed by rinsing the water nozzle 15, and the coating agent S4 is further applied by the top coating nozzle 46 and the side coating nozzle 47. FIG.

It should be noted that jetting from the top coating nozzles 46 and the side coating nozzles 47 may be started with a delay from the jetting from the top coating nozzles 41 and the side coating nozzles 42 .

Then, as shown in FIG. 8, when the upper surface coating nozzle 46 applies the coating agent S4 to the boundary P between the bonnet 70b and the front window 70w, the third outward process is completed, and the car wash main body 2 is reversed to perform the third return process. is done. A boundary P between the bonnet 70b and the front window 70w is detected by the shape sensor 9 in the first outward travel process.

At this time, the side coating nozzle 47 is arranged to apply the coating agent S4 to at least the rear end of the front door 70d. Although the rear end of the front door 70d differs depending on the type of the vehicle 70 to be washed, the coating agent S4 is applied by the side coating nozzle 47 to at least the rear portion of the front door 70d. In addition, the upper surface coating nozzle 41 and the side surface coating nozzle 42 advance to the rear portion of the vehicle 70 to be cleaned to apply the coating agent S4.

As a result, the third outbound process forms a first partial coating process of partially coating the vehicle 70 to be washed with the coating agent S4. In the first partial coating step, the top coating nozzle 41 continues to spray, and the top coating nozzle 46 coats the coating agent S4 from the front end of the vehicle 70 to be cleaned to the boundary P between the bonnet 70b and the front window 70w.

In the third return process, the car wash machine body 2 moves forward of the vehicle 70 to be washed (arrow E2). Then, the coating agent S4 is sprayed from the upper surface coating nozzles 41 and 46 and the side surface coating nozzles 42 and 47, and the washing water S2 of city water is sprayed from the water nozzles 12 and 13.

The coating agent S4 is overcoated by the upper surface coating nozzle 46 . Excessive coating agent S4 is removed by rinsing the water nozzle 13, and the coating agent S4 is further applied by the top surface coating nozzle 41 and the side surface coating nozzles 42, 47. Excess coating agent S4 is then removed by rinsing the water nozzle 12 .

The coating agent application step is completed by the end of the third return pass step, and the excessive coating agent is removed by the water nozzle 12 at this time, so that uneven coating can be reliably prevented.

When the coating agent S4 is applied to the front end of the vehicle 70 to be washed by the top surface coating nozzle 41 and the side surface coating nozzle 42, and rinsing is performed by the water nozzle 12, the third return process is completed. Thus, the third return process forms a second partial coating process of partially coating the vehicle 70 to be washed with the coating agent S4. In the second partial coating process, the top coating nozzles 41 and 46 and the side coating nozzles 42 and 47 each apply the coating agent S4 to the front end of the vehicle 70 to be cleaned.

Note that the car wash machine main body 2 may be moved at a higher speed (for example, 12 m/min) in the third outward process and the third return process than in the second return process.

In the third outward travel process and the third return travel process, the upper surface coating nozzle 46 applies the coating agent S4 to the bonnet 70b in front of the front window 70w. The side coating nozzle 47 applies the coating agent S4 to the front fender 70f and the front door 70d.

Further, the upper surface coating nozzle 41 applies the coating agent S4 to the bonnet 70b, the front window 70w, and at least part of the roof 70c. The side coating nozzle 42 applies the coating agent S4 to the front fender 70f, the front door 70d, and at least part of the rear door 70r.

Therefore, the number of applications of the coating agent S4 to the bonnet 70b, the front fender 70f, and the front door 70d of the vehicle 70 to be washed is greater than the number of applications to the roof 70c and the rear door 70r. Further, the number of applications of the coating agent S4 to the roof 70c and the rear door 70r of the vehicle 70 to be washed is greater than the number of applications to the rear (hatch and trunk).

The surface of the coated surface of the vehicle 70 to be washed is more likely to be damaged by collisions with stepping stones, insects, or the like as it moves forward, and the adsorption force of the coating agent S4 is weakened. For this reason, the coating agent S4 is applied more times to the front portion of the vehicle 70 to be washed than to the middle portion in the front-rear direction, and the coating agent S4 is applied more times to the middle portion than to the rear end portion. As a result, it is possible to form a coating film of the coating agent S4 with a desired thickness depending on the part that is easily damaged, and improve the coating performance such as water flowability.

At this time, since the front window 70w is not coated by the upper surface coat nozzle 46, an increase in the number of coatings on the front window 70w can be suppressed, and an oil film on the glass surface of the front window 70w can be suppressed.

After completion of the third return process, the fourth return process is performed in which the car wash machine main body 2 is reversed and moved to the rear of the vehicle 70 to be washed (arrow E1) as shown in FIG. In the fourth outbound process, the air flow A1 is sent out from the top blower nozzle 21 and the side blower nozzle 22 to dry the vehicle 70 to be washed. Thus, the fourth outward process forms a drying process for drying the vehicle 70 to be washed. When the fourth outbound process ends, the car wash ends, and the vehicle 70 to be washed moves forward.

According to the present embodiment, the first partial application process (third outward process) and the second partial application process (third return process) reduce the number of applications of the coating agent S4 to the front portion of the vehicle 70 to be washed to an intermediate value in the front-rear direction. It is possible to apply the coating agent S4 more times to the middle portion than to the rear end portion. Therefore, it is possible to form a film of the coating agent S4 with a desired thickness depending on the easily damaged portion, thereby improving the coating performance. In addition, it is possible to prevent an oil film from forming on the front window 70w by reducing the amount of coating agent applied to the front window 70w.

In addition, since the outward application process (second outward process) is provided before the return application process (second return process), the coating of the coating agent on the vehicle 70 to be washed can be formed thicker, and the coating performance can be improved. can be improved.

In addition, since the base nozzle 40 for spraying the water-repellent base material is provided prior to the top surface coat nozzle 41 (first top surface coat nozzle) during the outward coating process, the adsorption force of the coating material is increased, and the coating performance is further improved. can be improved.

Further, in the outward coating process (second outward process) or the first partial coating process (third outward process), if the jetting of the top coat nozzles 46 is started with a delay from the jetting of the top coat nozzles 41, the amount of coating agent can be reduced. can do.

In addition, when jetting from the top coat nozzle 41 is started after a delay from jetting from the top coat nozzle 46 in the backward coating process (second backward process), the amount of coating agent can be reduced.

Also, the coating agent is applied to the rear end of the front door 70d by the side coating nozzle 47 during the first partial coating process. Therefore, it is possible to form a sufficient film on the front door 70d, which is easily damaged, while reducing the number of times the front window 70w is coated.

Moreover, the injection angle θ of the side surface coating nozzles 42 and 47 is larger than the injection angle θ of the top surface coating nozzles 41 and 46 . Therefore, the coating agent can be dispersed on the upper surface of the vehicle 70 to be washed away from the upper surface coat nozzles 41 and 46 and the side surface of the vehicle to be washed 70 near the side surface coat nozzles 42 and 47 . As a result, the coating agent can be uniformly applied and the adsorption force can be increased.

Also, the injection pressure of the side surface coating nozzles 42 and 47 is higher than the injection pressure of the top surface coating nozzles 41 and 46 . Therefore, the coating agent can be made to collide with the side surface of the vehicle 70 to be washed near the side coating nozzles 42 and 47 at a high pressure to be dispersed more.

In addition, water is jetted from the water nozzles 13 between the top coating nozzles 41 and 46 in the second outward process, the second return process, the third outward process, and the third return process. Therefore, the excess coating agent sprayed by one of the upper surface coating nozzles 41 and 46 can be removed by rinsing, preventing uneven application of the coating agent and forming a uniform coating.

Also, water is jetted from the water nozzle 12 following the top coat nozzle 41 in the third return process. Therefore, when the application of the coating agent is completed, the excessive coating agent is removed by the water nozzle 12, and uneven application can be reliably prevented.

In this embodiment, the forward coating step may be omitted. For example, the forward coating process can be omitted by using the first forward process as the cleaning process and the first backward process as the backward coating process. Thereby, car wash time can be shortened.

INDUSTRIAL APPLICABILITY According to the present invention, it can be used in a car washing machine that applies a coating agent to a vehicle to be washed.
