As a result, the car wash can be effectively implemented regardless of the layout.

Hereinafter, the operation of the car wash apparatus of the present invention configured as above will be described.
First, when the admission control board 37 detects entry of an automobile by any means, a predetermined announcement is output from the voice guide unit 47 to enter the car wash acceptance state. When the user correctly specifies the car wash menu, toppings, protrusions, and charges on the reception operation panel 40, the car wash reception is completed, and a car wash request signal is output to the car wash control board 36.

When the car wash request signal is input from the reception control board 37, the car wash control board 36 determines whether or not the received car wash includes underbody washing for topping. Here, when the vehicle body lower part washing is not set, the gate device 34 is opened to permit entry into the car washing space A, and guidance display 35 is displayed to prompt the driver to move forward. Following the guidance of the guidance indicator 35, the vehicle enters along the guide rails 5R and 5L, and when the tire mounting plates 7R and 7L are stopped as a guide, the photoelectric switch 21 switches from light transmission to light shielding and the gate device. 34 is closed to prohibit a succeeding vehicle from entering the car wash space A, and a guidance display for prompting a stop is displayed on the guidance display 35.

When it is confirmed that the vehicle stays at the stop position for a predetermined time, the guide display 35 displays a guide for starting the car wash, and the car wash is executed according to the selected car wash menu. If the photoelectric switch 21 is switched to the translucent state before a predetermined time elapses, a guidance display prompting the driver to move forward is displayed on the guidance display 35, and when the vehicle shape unit 20 detects the vehicle body, the guidance display 35 moves backward. Is displayed.

When the car wash starts, the traveling position of the frame 8 and the top surface contour data of the automobile are created by the traveling position detection device and the vehicle shape detection device in the first forward process accompanying the forward movement of the frame 8, and the brushes are controlled to control the vehicle body. Brushing. After that, the brushing cleaning is performed again in the first backward process accompanying the backward movement of the frame 8, and the nozzles are controlled in the second forward process following the forward movement of the frame 8 to dry the vehicle body. In this way, the frame 8 travels to the car wash end position Ep at the front end of the rail given by the dog 10b, and the car wash ends.

When the car wash is finished, a display prompting the exit is displayed on the guide display 35, and when the photoelectric switch 22 shifts from light blocking to light transmitting, the frame 8 is retracted and returned to the start position after a predetermined time has elapsed. If the area sensor 23 is in the detection state during the backward movement of the frame 8, it is judged that there is an obstacle such as a leaving vehicle and the traveling of the frame 8 is stopped. When the area sensor 23 is not detected, the backward movement of the frame 8 is resumed, and when the frame 8 returns to the starting position of the rear end of the rail, the traveling of the frame 8 is stopped and the vehicle waits for the next car wash.

Now, the case where the vehicle body lower part washing is set for the topping will be described below with reference to the operation explanatory view of FIG.
The vehicle body lower part washing is executed in the first backward process accompanying the backward movement of the frame 8 based on the upper surface contour data of the automobile created in the first forward process. When the first returning step is started, brush cleaning is performed in the gate type car wash machine 1, and jet cleaning is performed in the lower cleaning device 4 by operating the high pressure pump to inject cleaning water to the lower surface of the vehicle body. At this time, the length from the front end to the rear end of the vehicle body (that is, vehicle length) is extracted from the upper surface contour data of the vehicle created in the first forward process, and the high pressure pumps 32a to 32c that are driven based on this vehicle length are selected. Works properly.

That is, if the extracted vehicle length is less than 3.5 m in the light vehicle class, only the high-pressure pump 32a is driven to inject the wash water from the injection nozzle 25 of the first fountain pipes 24Ra and 24La to the lower surface of the vehicle body (Fig. 6a). .. If the extracted vehicle length is less than 4.5 m, which is the size of a small ordinary vehicle class, the high-pressure pump 32a and the high-pressure pump 32b are driven, and the first fountain pipes 24Ra and 24La and the second fountain pipes 24Rb and 24Lb from the injection nozzle 25 to the underside of the vehicle body. The cleaning water is sprayed on (Fig. 6b). If the extracted vehicle length is 4.5 m or more, all the high-pressure pumps 32a to 32c are driven to eject the first fountain pipes 24Ra, 24La, the second fountain pipes 24Rb, 24Lb, and the third fountain pipes 24Rc, 24Lc. To spray cleaning water onto the bottom of the vehicle (Fig. 6c).

In this way, by limiting the fountain pipe 24 of the lower cleaning device 4 according to the length of the vehicle, it is possible to prevent scattering to the outside, and at the same time save water. The injection from each injection nozzle 25 acts on the lower surface of the hem part on the side surface of the vehicle body, centering around the tire house where the vehicle body lower surface is particularly dirty, and exerts cleaning power, and the cleaning water is sprayed over a wide range. Can be confirmed, and the visual appeal effect is great.

Among the injection nozzles 25, the injection nozzle 25-1 located on the vehicle front end side of the first fountain pipes 24Ra and 24La has a linear injection pattern in which the vehicle center side in the vehicle width direction is closer to the vehicle side surface than the vehicle side surface side. Since it is adjusted to the rear of the vehicle, the injection to the lower surface of the front end of the automobile does not scatter outside regardless of the vehicle type. Further, the injection nozzle 25-9 located on the rear end side of the vehicle of the first fountain pipes 24Ra and 24La, the injection nozzle 25-11 located on the rear side of the second fountain pipes 24Rb and 24Lb, and the third fountain pipe 24Rc. The injection nozzle 25-13 located on the rear side of the 24Lc is adjusted so that the linear injection pattern is arranged so that the vehicle center side is located in front of the vehicle rather than the vehicle side surface in the vehicle width direction. Irrespective of the length, the injection to the lower surface of the rear end of the automobile does not scatter to the outside.

Although the present invention is configured as described above, the present invention is not limited to the above-described embodiments. As for the gate-type car wash machine, a car wash machine that does not include a brush device and that cleans the vehicle body with high-pressure spray or the like may be used, or a car wash machine that is not a drive-through type but a service person may wash the car body.

As for the lower cleaning device, the number of jet nozzles and the jetting direction are not limited to those in the above embodiment, and can be set appropriately, and the jetting nozzle can be swung freely by a swinging mechanism using an air cylinder and a link rod. It can also be formed. Further, the number of divided fountain pipes is not particularly limited, and the fountain pipes may be arranged so as to extend not in the vehicle length direction but in the vehicle width direction. Furthermore, it is also possible to give the same operation as that of the conventional lower cleaning device, such as spraying water from a fountain pipe in accordance with the entry of an automobile.

In addition to the fan-shaped nozzle, the spray nozzle is an empty cone nozzle that diffuses in a conical shape from the spray port to give a circular spray pattern to the cleaning surface, or a spray cone that scatters in a cone shape from the spray port and fills the cleaning surface. A full-cone nozzle that gives Although the fountain pipe is buried in the groove on the floor, it may be laid on the floor.
