Further, the pipe 80 is led out to the outlet side of the distribution pipe unit 31. The pipe 80 is provided with a pump 81 that sends out water or the like at a pressure higher than that of the pump 43. By driving the pump 81, city water or water containing detergent is ejected from the cleaning nozzle 78.

In the car wash machine WA having the above configuration, the car wash machine main body 1 is arranged at the standby position and the traveling body 73 is arranged at the start point S0 as shown in FIG. 1 at the end of the previous car wash. By the user's driving, the vehicle CA to be washed stops at the reception position T0 in front of the remote panel 7, the car wash conditions of the vehicle CA to be washed are set, and the car wash is accepted. The vehicle CA to be washed, which has received the car wash, advances the approach road R by the user's driving, and the pre-washing device 70 performs the pre-washing.

8 to 10 are side views showing the operation of the preliminary cleaning device 70. As shown in FIG. 8, when the acceptance of the car wash is completed, the traveling body 73 is arranged at the predetermined watering position S1. The cleaning nozzle 78 at the watering position S1 is arranged behind the detection sensor 68 and in front of the sensor 68b in the traveling direction of the vehicle CA to be cleaned. The traveling body 73 may be arranged at the watering position S1 at the end of the previous car wash.

As shown in FIG. 9, when the vehicle CA to be washed moving forward on the approach road R is detected by the rear sensor 68b of the detection sensor 68, the pump 43 and the pump 81 are driven. As a result, high-pressure water is sprayed from the washing nozzle 78 onto the vehicle CA to be washed moving forward on the approach road R, and the vehicle CA to be washed is washed with water. Since the pumps 43 and 81 are driven when the vehicle CA to be washed is detected by the detection sensor 68, the water injection is stopped between the acceptance of the car wash and the detection of the detection sensor 68. Therefore, water can be saved.

At this time, since the cleaning nozzle 78 at the watering position S1 is arranged in front of the rear sensor 68b in the traveling direction of the vehicle CA to be cleaned, water can be sprinkled on the vehicle CA to be cleaned from the front end.

Further, when the rear sensor 68b detects the vehicle CA to be cleaned and a predetermined time elapses, the traveling body 73 at the sprinkling position S1 moves a predetermined distance to the rear in the traveling direction of the vehicle CA to be cleaned. As a result, water can be poured to the rear end of the vehicle CA to be washed of a large vehicle.

When the acceptance of the car wash is completed, the high-pressure pump 81 may be stopped to drive the low-pressure pump 43, and low-pressure water may be injected from the washing nozzle 78. Since low-pressure water is injected from the cleaning nozzle 78, the amount of water is small and water can be saved. As a result, the user of the vehicle to be cleaned CA moving forward on the approach road R can be made aware that the cleaning by the cleaning nozzle 78 is performed.

Further, the cleaning nozzle 78 at the watering position S1 may be arranged in front of the front sensor 68a in the traveling direction of the vehicle to be cleaned, and the pump 81 may be driven when the vehicle CA to be cleaned is detected by the front sensor 68a.

As shown in FIG. 10, when the vehicle CA to be washed is arranged at the car wash start position T1, the traveling body 73 moves forward in the traveling direction of the vehicle CA to be washed and the water injection by the washing nozzle 78 is continued. At this time, since the vehicle to be washed CA is already splashed with water when advancing on the approach road R, the traveling body 73 can be moved at high speed.

When the traveling body 73 is arranged at the end point S2 of the stroke, it reverses and moves toward the start point S0, drives the pumps 43 and 81, and ejects the detergent from the cleaning nozzle 78. At this time, the cleaning nozzle 78 sprays the foamed detergent, and the surface of the vehicle CA to be cleaned is covered with the foamed detergent.

When the injection region of the cleaning nozzle 78 is arranged at the rear end of the vehicle length classified by the detection of the detection sensor 68, the pump 43 and the pump 81 are stopped. Then, the traveling body 73 is arranged at the starting point S0, the preliminary cleaning is completed, and the car wash machine main body 1 is washed with the rotating brush as described later.

Since the surface of the vehicle CA to be cleaned is covered with the foaming detergent before cleaning with the rotary brush, the cleaning power for the vehicle CA to be cleaned can be improved. Further, since the process of covering the vehicle CA to be cleaned with the foaming detergent can be easily visually recognized from the surroundings, a show-like effect can be obtained, and the user can have a feeling of expectation that the cleaning effect will be improved.

When the vehicle CA to be cleaned is arranged at the vehicle wash start position T1, the pumps 43 and 81 are stopped, the traveling body 73 is returned to the starting point S0, and the detergent is removed from the cleaning nozzle 78 that moves toward the front of the vehicle CA to be cleaned. May be sprayed.

When the pre-washing is completed, the car wash machine main body 1 moves toward the rear of the vehicle to be washed CA, and the first outbound process is performed. In the first outbound process, while the shape sensor 9 detects the shape of the vehicle CA to be cleaned, each rotating brush rotates to clean the front and rear surfaces and the upper surface of the vehicle CA to be cleaned. At this time, the detergent is ejected from the injection nozzle 11.

When the washing is completed up to the rear surface of the vehicle CA to be washed, the first return route step is performed in which the car wash machine main body 1 is inverted and moved to the front of the vehicle CA to be washed. In the first return step, water is ejected from the injection nozzle 11 while the rotating brush rotates. Further, the traveling body 73 follows the car wash machine main body 1 and moves toward the front of the vehicle CA to be washed, and water is ejected from the washing nozzle 78. As a result, the detergent is rinsed and washed.

At this time, based on the detection result of the shape sensor 9, when the traveling body 73 is arranged in a predetermined section to be ejected from the cleaning nozzle 78 in the region where bubbles are likely to remain, the traveling body 73 is temporarily stopped. Areas where bubbles are likely to remain include the front wiper portion and the boundary between the rear window and the trunk. Thereby, the rinsing performance can be improved.

The traveling speed of the traveling body 73 may be set to be lower than that outside the section, or the traveling body 73 may be reciprocated in the section. That is, the injection time of the cleaning nozzles 78 arranged in the predetermined section may be longer than that outside the section.

When the first return path process is completed, the cleaning process of the vehicle CA to be cleaned is completed, and the rotary brush is stopped. Next, a drying step by the second outbound process is performed, and an air flow is sent from the top blower nozzle 21 and the side blower nozzle 22 to dry the vehicle CA to be cleaned. When the drying process is completed, the car wash is completed and the vehicle to be washed CA leaves.

When the vehicle to be washed CA exits, the car wash machine main body 1 moves to the standby position and the traveling body 73 moves to the starting point S0.

When the coating agent or wax is applied to the vehicle CA to be cleaned, a step of injecting the coating agent or wax from the injection nozzle 11 is provided between the cleaning step and the drying step.

According to the present embodiment, when the vehicle CA to be washed moving forward on the approach road R is detected by the detection sensor 68, water is injected from the washing nozzle 78 previously arranged at the watering position S1, so that the vehicle is stopped at the car washing start position T1. The spraying of the detergent on the vehicle CA to be cleaned can be started at an early stage. Therefore, the car wash time of the car wash machine WA can be shortened. Further, since the amount of water used can be reduced between the acceptance of the car wash and the detection by the detection sensor 68, water can be saved.

Further, when the vehicle to be washed stops at the car wash start position T1, the washing nozzle 78 moves forward in the traveling direction of the vehicle to be washed CA to inject water, so that the washing power of the car wash machine WA can be further improved. .. Further, since the vehicle CA to be cleaned is splashed with water at the time of approaching, the cleaning nozzle 78 can be moved at high speed, and water can be saved.

Further, the cleaning nozzle 78 at the watering position S1 is arranged in front of the detection sensor 68 in the traveling direction of the vehicle CA to be cleaned. As a result, water can be poured from the front end onto the vehicle CA to be washed moving forward on the approach road R, and the cleaning power of the car wash machine WA can be further improved.

Further, the detection sensor 68 detects the vehicle CA to be cleaned moving forward on the approach road R, and after a predetermined time elapses, the cleaning nozzle 78 moves a predetermined amount to the rear in the traveling direction of the vehicle CA to be cleaned. As a result, even if the length of the vehicle to be washed CA is long, water can be poured to the rear end, and the cleaning power of the car wash machine WA can be further improved.

Further, between the acceptance of the car wash and the detection of the vehicle CA to be washed by the detection sensor 68, water having a lower pressure than that after the detection is injected from the washing nozzle 78. As a result, the user of the vehicle to be cleaned CA moving forward on the approach road R can be made aware that the cleaning by the cleaning nozzle 78 is performed. Therefore, it is possible to prevent the user from feeling uneasy due to the sudden injection of high-pressure water in front of him.

Further, since the moving range of the cleaning nozzle 78 in the front-rear direction is changed based on the detection result of the detection sensor 68, waste of water and detergent can be reduced.

According to the present invention, it can be used in a car wash machine in which a washing nozzle is provided in a frame installed in an approach path to the car wash machine main body.
