It is provided with a voice guide unit 48 that performs voice.

The guidance display 36 is installed behind the exit of the car wash space so that the car entering from the entrance of the car wash space can be visually recognized and does not get in the way when exiting after the car wash. The display may be positioned on the exit path of the vehicle during car washing so that it can be easily seen from the driver's seat of the vehicle being washed, and the indicator may be oscillated so as to retract from the exit path of the vehicle when exiting the vehicle. As a result, the car wash can be effectively carried out regardless of the layout.

Hereinafter, the operation of the car wash device of the present invention configured in this way will be described.
First, when the reception control board 38 detects the entry of a vehicle by any means, the voice guide unit 48 outputs a predetermined announcement to enter the vehicle wash reception state. When the user correctly specifies the car wash menu, toppings, protrusions, and the charge settlement on the reception operation panel 41, the car wash reception is completed and the car wash request signal is output to the car wash control board 37.

When the car wash request signal is input from the reception control board 38, the car wash control board 37 opens the gate device 35 to allow entry to the car wash space A and displays a guidance display prompting the advance on the guidance display 36. .. The driver enters the automobile along the guide rails 4 and 4 according to the guidance of the guide indicator 36, and stops the vehicle with the tire mounting plates 6 and 6 as a guide. When it is confirmed that the photoelectric switch 21 has changed from translucent to light-shielded in the waiting car wash machine, the gate device 35 is closed to prohibit the following vehicle from entering the car wash space A, and the guidance display 36 is stopped. Prompt guidance is displayed.

When the photoelectric switch 21 continues to block light for a predetermined time, it is determined that the vehicle has stopped at the stop position, a guidance for starting the vehicle wash is displayed on the guidance display 36, and the vehicle is washed according to the selected car wash menu. If the photoelectric switch 21 turns to translucent light before the lapse of a predetermined time, a guidance display prompting the vehicle to move forward is displayed on the guidance display 36, and when the vehicle-shaped sensor 20 detects the vehicle body, the guidance display 36 moves backward. Display to prompt. That is, the photoelectric switch 21 in front of the car wash machine blocks light, and the vehicle-shaped sensor 20 in the car wash machine continues to transmit light for a predetermined time, so that the vehicle is stopped.

When the car wash starts, the traveling position of the main body frame 1 and the top contour data of the automobile are created by the traveling position detecting device and the vehicle shape detecting device in the first forward process accompanying the advancement of the main body frame 1, and each brush is controlled. Brush the car body. After that, brushing cleaning is performed again in the first return step accompanying the reverse movement of the main body frame 1, and each nozzle is controlled to dry the vehicle body in the second forward step accompanying the re-advancement of the main body frame 1. In this way, the main body frame 1 travels to the car wash end position at the front end of the rail given by the dog 10b, and the car wash is completed.

When the car wash is completed, a display prompting the exit is displayed on the guidance display 36, and when the photoelectric switch 22 changes from shading to translucent, the main body frame 1 is retracted and returned to the starting position after a lapse of a predetermined time. If the area sensor 23 is in the detection state while the main body frame 1 is retracting, it is determined that there is an obstacle such as a moving vehicle and the main body frame 1 is stopped. When the area sensor 23 is not detected, the retreat of the main body frame 1 is restarted, and when the main body frame 1 returns to the start position of the rear end of the rail, the running of the main body frame 1 is stopped and the next car wash is awaited.

Now, a case where the lower part of the vehicle body is set to be washed will be described.
The lower part of the vehicle body cleaning is executed in the first return step accompanying the reverse movement of the main body frame 1 based on the front end position and the rear end position of the automobile detected in the first forward step. When the first restoration step is started, brushing cleaning is performed with a cleaning brush, and the lower cleaning device 3 operates a high-pressure pump 31 to perform jet cleaning in which cleaning water is sprayed onto the lower surface of the vehicle body. At this time, the cleaning units 3A to 3C operated by the lower cleaning device 3 are selected based on the rear end position of the vehicle body detected in the first forward step.

As shown in FIG. 6A, if the detected rear end position of the vehicle body is within the range of the first cleaning unit 3A, the solenoid valves 33a and 33b are driven to inject cleaning water from the first cleaning unit 3A onto the lower surface of the vehicle body. To do. At this time, the solenoid valve 33a and the solenoid valve 33b are opened and closed in order at predetermined intervals, and the fountain pipe 24a and the fountain pipe 24b are alternately injected. As a result, the operation of injecting inward from the fountain pipe 24a and the operation of injecting outward from the fountain pipe 24b are repeated, and a wide range of cleaning is performed without increasing the amount of water, and the rocking cleaning is performed. Gives the impression that is being performed, and visually appeals the high cleaning effect. Of course, it is also possible to open the electromagnetic valves 33a and 33b and inject from the fountain pipe 24a and the fountain pipe 24b at the same time, and since the injection nozzles 26 of the fountain pipe 24a and the fountain pipe 24b are staggered, they interfere with each other. The wash water can be allowed to act without any action.

As shown in FIG. 6B, if the detected rear end position of the vehicle body is within the range of the second cleaning unit 3B, the solenoid valves 33a, 33b, 33c are driven to drive the first cleaning unit 3A and the second cleaning unit 3B. The washing water is sprayed onto the underside of the vehicle body. At this time, the solenoid valve 33c → the solenoid valve 33a → the solenoid valve 33b is opened and closed in order at predetermined intervals, and the fountain pipe 24c, the fountain pipe 24a, and the fountain pipe 24b are injected. Since the fountain pipe 24c of the second cleaning unit 3B includes an injection nozzle 26 that injects inward of the vehicle body and an injection nozzle 26 that injects outward of the vehicle body, it is visually possible to clean the rear part of the vehicle body in a wide range. It is highly appealing to.

As shown in FIG. 6C, if the detected rear end position of the vehicle body is within the range of the third cleaning unit 3C, the solenoid valves 33a, 33b, 33c, 33d are driven to drive the first cleaning unit 3A, the second cleaning unit 3A, and the second cleaning unit. Cleaning water is sprayed from the parts 3B and the third cleaning part 3C to the lower surface of the vehicle body. At this time, the solenoid valve 33d → the solenoid valve 33c → the solenoid valve 33a → the solenoid valve 33b is opened and closed in order at predetermined intervals, and the fountain pipe 24d, the fountain pipe 24c, the fountain pipe 24a, and the fountain pipe 24b are injected. Since the fountain pipe 24c of the second cleaning unit 3B and the fountain pipe 24d of the third cleaning unit 3C each include an injection nozzle 26 that injects inward of the vehicle body and an injection nozzle 26 that injects outward of the vehicle body, the vehicle body Extensive cleaning of the rear is visually appealing.

In this way, by changing the cleaning portion that operates according to the position of the rear end of the vehicle body, scattering to the outside can be reduced and unnecessary injection can be reliably prevented. The injection from each injection nozzle 26 acts on the lower surface of the hem on the side surface of the vehicle body, mainly around the tire house, which is particularly dirty on the lower surface of the vehicle body, exerts cleaning power, and sprays cleaning water over a wide area without waste. It can be confirmed that the tires are used, and the visual appeal effect is also great. In addition, in order to further reduce the scattering to the outside, the cleaning unit that operates may be switched according to the traveling position of the main body frame 1. In this case, when the main body frame 1 is on the third cleaning unit 3C, the fountain pipe 24d of the third cleaning unit 3C is sprayed, and when the main body frame 1 is on the second cleaning unit 3C, the second cleaning unit is ejected. It is injected from the fountain pipe 24c of 3B, and when the main body frame 1 is on the first cleaning unit 3A, it is alternately injected from the fountain pipe 24a and the fountain pipe 24b of the first cleaning unit 3A.

Further, in the above-described embodiment, the lower part cleaning is performed in the return process based on the front end and the rear end of the vehicle body detected in the forward process, but it is also possible to execute the lower part cleaning from the forward process. That is, since the rear end position of the vehicle body is determined by the vehicle shape sensor 20 as the main body frame moves forward, the second cleaning unit 3B is recognized when the vehicle body exists up to the second cleaning unit 3B and the third cleaning unit 3C. And the third cleaning unit 3C are operated.

As for the gate-type car wash machine, a car wash machine that does not have a brush device and that cleans the vehicle body with a high-pressure spray or the like may be used, or a car wash machine that is not a drive-through method but a serviceman wash the car. Further, by installing the detection device on the floor at the front end and the rear end of the vehicle body, there is no gate type car wash machine, and only the lower cleaning device can be used.

Regarding the lower cleaning device, the number of injection nozzles and the injection direction are not limited to the above-described embodiment, and can be appropriately set, and the injection nozzles can be freely swung by a swing mechanism using an air cylinder and a link rod. It is also possible to form. Further, the number of fountain pipes to be divided is not particularly limited, and the fountain pipes may be arranged so as to extend in the vehicle width direction instead of the vehicle length direction.

Regarding the injection nozzle, in addition to the fan-shaped nozzle, an empty conical nozzle that diffuses in a conical shape from the injection port and gives a circular injection pattern to the cleaning surface, and a conical nozzle that diffuses in a conical shape from the injection port and fills the cleaning surface. A conical nozzle that gives an injection pattern can be adopted. Further, regarding the fountain pipe, although it is laid on the floor surface, it may be buried in a groove on the floor surface.
