A plurality of injection nozzles 53a are arranged side by side in the injection unit 53, and a plurality of injection nozzles 54a are arranged side by side in the injection unit 54 in the front-rear direction. The injection nozzles 51a to 54a (second injection nozzles) inject tap water for washing water upward. Further, as will be described in detail later, the injection nozzles 51a to 54a inject cleaning water having a higher pressure than the cleaning nozzles 11 to 14.

In the present embodiment, the rearmost injection nozzle 52a of the injection unit 52 is arranged at a position 3.2 m from the front injection nozzle 51a of the injection unit 51. The rearmost injection nozzle 53a of the injection unit 53 is arranged at a position 4.3 m from the front injection nozzle 51a of the injection unit 51. The rearmost injection nozzle 54a of the injection unit 54 is arranged at a position 4.8 m from the front injection nozzle 51a of the injection unit 51.

FIG. 4 shows a piping diagram of the water supply path of the car wash machine 1. A water storage tank 33 for storing tap water is installed on the outside of the outlet surface 2b of the car wash machine main body 2. Water other than tap water (for example, well water, groundwater, river water, recovered water) may be stored in the water storage tank 33.

A water pump 34 for pumping water is immersed in the water storage tank 33. A high-pressure pump 35 is connected to the drain side of the water pump 34 via a three-way valve 36. The high-pressure pump 35 raises the water pressure of the washing water and sends it out, and a high-pressure water supply path 42 for supplying high-pressure (for example, 2 MPa) tap water is formed downstream of the high-pressure pump 35. Further, a pipe is branched between the three-way valve 36 and the high-pressure pump 35, and a low-pressure water supply path 41 for supplying tap water having a lower pressure (for example, 0.2 MPa) than the high-pressure water supply path 42 is formed.

An air pump 37 that supplies high-pressure compressed air is connected to the three-way valve 36. By switching the three-way valve 36, air and tap water are selectively circulated in the low-pressure water supply path 41 and the high-pressure water supply path 42. High-pressure air is supplied to the low-pressure water supply path 41 and the high-pressure water supply path 42 after the car is washed. As a result, the cleaning nozzles 11 to 14, the wax nozzles 15, and the injection nozzles 51a to 54a (see FIG. 4) are drained.

The low-pressure water supply path 41 is branched into a plurality of branches and is connected to the cleaning nozzles 11 to 14 and the wax nozzle 15 via the solenoid valve 39, respectively. By turning on / off each solenoid valve 39, the execution and stop of the injection of cleaning water and wax by the cleaning nozzles 11 to 14 and the wax nozzle 15 are switched.

As a result, the cleaning water of tap water is ejected from the cleaning nozzles 11 to 13. Further, an injector 47 is arranged upstream of the cleaning nozzle 14. The suction portion 43 connected to the injector 47 via the check valve 45 is immersed in the liquid storage tank 31 for storing the detergent. The detergent in the liquid storage tank 31 is sucked into the injector 47 by the water flowing through the pipe, and the cleaning water containing the detergent is supplied to the cleaning nozzle 14.

Similarly, an injector 48 is arranged upstream of the wax nozzle 15. The suction portion 44 connected to the injector 48 via the check valve 46 is immersed in the liquid storage tank 32 for storing the wax. The wax in the liquid storage tank 32 is sucked into the injector 48 by the water flowing through the pipe, and the wax diluted to a predetermined concentration is supplied to the wax nozzle 15. The check valves 45 and 46 prevent the inflow of tap water into the liquid storage tanks 31 and 32. The injection nozzle for injecting the coating agent is connected in the same manner as the wax nozzle 15.

The high-pressure water supply path 42 branches into a plurality of branches downstream of the high-pressure pump 35, and is connected to the injection units 51 to 54 via a solenoid valve 38, respectively. By turning on / off each solenoid valve 38, the execution and stop of the injection of the washing water by the injection units 51 to 54 are switched.

The cleaning nozzles 11 to 14 and the wax nozzle 15 may be provided in the high-pressure water supply path 42.

In the car wash machine 1 having the above configuration, when the vehicle to be washed 70 stops in front of the remote panel 65, the car wash conditions are set. After setting the car wash conditions, the car wash is started when the vehicle to be washed 70 moves to a predetermined wash start position and stops by the user's driving.

By operating the remote panel 65, a car wash course including a water wash course, a shampoo course, a wax course, and a coating course can be selected. In the washing course, the rotating brush is rotated to inject washing water, and the vehicle to be washed 70 is washed with water. In the shampoo course, the rotating brush is rotated to inject washing water containing detergent, and the vehicle to be washed 70 is washed with detergent.

In the wax course, the vehicle to be cleaned 70 is washed in the same manner as the shampoo course, and then wax is applied to the vehicle to be cleaned 70 by the wax nozzle 15. In the coating course, the vehicle to be cleaned 70 is washed in the same manner as the shampoo course, and then the coating agent is applied to the vehicle to be cleaned 70.

The bottom surface cleaning device 50 switches the injection units 51 to 54 for injecting cleaning water based on the length of the vehicle to be cleaned 70 detected by the shape sensor 9 (see FIG. 2). That is, as shown in FIG. 5, cleaning water is injected from the injection unit 51 and the injection unit 52 to a small vehicle to be cleaned 70 (light vehicle, compact car, etc.) having a vehicle length of less than 4.4 m.

As shown in FIG. 6, washing water is injected from the injection unit 51, the injection unit 52, and the injection unit 53 to a medium-sized vehicle to be cleaned 70 (middle class sedan, etc.) having a vehicle length of 4.4 m or more and less than 4.7 m. Will be done. As shown in FIG. 7, for a large vehicle to be cleaned 70 (wagon vehicle, minivan, etc.) having a vehicle length of 4.7 m or more, cleaning water is discharged from the injection unit 51, the injection unit 52, the injection unit 53, and the injection unit 54. Be jetted.

Therefore, when cleaning the lower surface of the vehicle 70 to be cleaned, the front injection unit 51 and the injection unit 52 adjacent to the rear of the injection unit 51 inject cleaning water regardless of the vehicle length of the vehicle 70 to be cleaned. .. The length of the vehicle to be cleaned 70 may be further subdivided to provide a corresponding injection unit.

FIG. 8 shows a time chart of the shampoo course for the large vehicle to be washed 70. 8 (a) to 8 (g) show the operations of the shape sensor 9, the rotating brush (top brush 5 and side brush 6), the injection unit 51, the injection unit 52, the injection unit 53, the injection unit 54, and the blower 20, respectively. There is.

When the car wash is started at time t0, the first outbound route A1 in which the car wash machine main body 2 moves toward the rear of the vehicle to be washed 70 at a predetermined moving speed (for example, 5 m / min) is performed. In the first outbound route A1, the shape sensor 9 arranged at the end on the entrance surface 2a side is driven to detect the vehicle shape of the vehicle to be washed 70.

Further, the top brush 5 and the side brush 6 following the shape sensor 9 are rotationally driven, and the cleaning water of tap water is ejected from the cleaning nozzles 11 and 12, and the cleaning water containing detergent is ejected from the cleaning nozzle 14. As a result, the top brush 5 and the side brush 6 slide on the vehicle body surface of the vehicle 70 to be washed wet with the washing water, and are washed with the washing water containing detergent. At this time, the top brush 5 moves along the upper surface of the vehicle to be cleaned 70 detected by the shape sensor 9.

When the shape sensor 9 detects the rear end of the vehicle to be washed 70, the length of the vehicle to be washed 70 is acquired. As a result, the moving stroke of the car wash machine main body 2 is changed according to the vehicle length, and the shape sensor 9 is stopped.

When the cleaning of the rear surface of the vehicle to be cleaned 70 is completed by the side brush 6 at time t10, the car wash machine main body 2 is inverted at the stroke end and the first return path B1 is started. On the first return route B1, the car wash machine main body 2 moves toward the front of the vehicle to be washed 70 at the same moving speed or high speed as the first outward route A1. Further, the top brush 5 and the side brush 6 are continuously rotationally driven, and the cleaning water of tap water is ejected from the cleaning nozzle 13. The detergent is rinsed by the top brush 5 and the side brush 6 that follow the cleaning nozzle 13.

Further, when the first return path B1 is started, cleaning is performed by the bottom surface cleaning device 50. Injection units 51 to 54 for injecting wash water are selected based on the vehicle length detected by the shape sensor 9. Here, since it is a large vehicle to be cleaned 70, cleaning water is injected from the injection unit 51, the injection unit 52, the injection unit 53, and the injection unit 54.

At this time, the injection units 51 to 54 are sequentially switched at times T1 to T4 to inject the washing water. That is, the injection by the injection unit 51 is performed at time t10, the injection by the injection unit 51 is stopped at time t12, and the injection by the injection unit 52 is performed. Further, at time t13, the injection by the injection unit 52 is stopped and the injection by the injection unit 53 is performed, and at time t14, the injection by the injection unit 53 is stopped and the injection by the injection unit 54 is performed.

As a result, the injection time T0 of the cleaning water by the bottom surface cleaning device 50 is T1 + T2 + T3 + T4. Since the injection speed of the cleaning water can be increased by switching the injection units 51 to 54 in order, the cleaning force with respect to the lower surface of the vehicle to be cleaned 70 can be increased. The order of switching the injection units 51 to 54 is not limited to the order from the front, and the injection units 51 to 54 may be switched in a desired order.

The time t20, which is the end time of washing with the rotating brush, can be obtained from the vehicle length detected by the shape sensor 9 on the first outward route A1 and the moving speed of the car wash machine main body 2 on the first return route B1. The injection time T0 of the bottom surface cleaning device 50 is set so as not to exceed the time from the time t10 to the time t20. The times T1 to T4 are allocated to the injection time T0 according to the quantity ratio of the injection nozzles 51a to 54a of the injection units 51 to 54 and the like.

As shown in FIG. 8, if each time T1 to T4 of the injection units 51 to 54 can be secured with a sufficient length for cleaning, the injection time T0 may be set shorter than the time from time t10 to time t20. good. At this time, the cleaning by the bottom surface cleaning device 50 is completed before the cleaning by the rotating brush is completed. The injection time T0 may be matched with the time from time t10 to time t20, and the cleaning by the bottom surface cleaning device 50 may be completed when the cleaning by the rotating brush is completed.

The injection time T0 may be derived by calculation from the length of the vehicle to be washed 70 and the moving speed of the car wash machine main body 2. Further, a table of injection time T0 classified according to the length of the vehicle to be washed 70 and the moving speed of the car wash machine main body 2 may be stored in advance, and the injection time T0 may be extracted from the table.

When the cleaning of the front surface of the vehicle to be cleaned 70 is completed by the side brush 6 at time t20, the car wash machine main body 2 is inverted at the stroke end and the second outbound route A2 is started. On the second outbound route A2, the car wash machine main body 2 moves toward the rear of the vehicle to be washed 70, stops the rotating brush, and stops the injection of each injection nozzle. Then, the blower 20 is driven to blow air from the top blower nozzle 21 and the side blower nozzle 22, and the vehicle to be washed 70 is dried.

When the rear surface of the vehicle to be washed 70 is dried at time t30 and the car wash is completed, the vehicle to be washed 70 moves forward and exits. After that, the car wash machine main body 2 returns to the initial position. As a result, the car wash machine main body 2 reciprocates 1.5 times to wash the shampoo course.

Next, FIG. 9 shows a time chart of the shampoo course for a light vehicle which is a small vehicle to be washed 70. Each device of FIGS. 9 (a) to 9 (g) is the same as the above-described devices of FIGS. 8 (a) to 8 (g).

At time t0, the first outbound route A1 is performed in the same manner as in FIG. 8, and the moving stroke of the car wash machine main body 2 by the detection of the shape sensor 9 is shorter than that in the case of the large-sized vehicle to be washed 70. In the first return path B1, cleaning is performed by a rotating brush, and cleaning water is injected from the injection unit 51 and the injection unit 52 of the bottom surface cleaning device 50 according to the vehicle length of the vehicle 70 to be cleaned.

At this time, the injection units 51 and 52 inject the cleaning water in order at times T1 and T2, respectively, and the injection time T0 of the cleaning water by the bottom surface cleaning device 50 is T1 + T2. The injection time T0 of the bottom surface cleaning device 50 is set so as not to exceed the time from the time t10 to the time t20.

As shown in FIG. 9, if each time T1 to T2 of the injection units 51 and 52 can be secured with a sufficient length for cleaning, the injection time T0 may be set shorter than the time from time t10 to time t20. good. At this time, the cleaning by the bottom surface cleaning device 50 is completed before the cleaning by the rotating brush is completed. The injection time T0 may be matched with the time from time t10 to time t20, and the cleaning by the bottom surface cleaning device 50 may be completed when the cleaning by the rotating brush is completed.

Then, at time t20, the vehicle shifts to the second outbound route A2 to dry the vehicle to be washed 70, and the car wash is completed at time t30.

FIG. 10 shows a time chart of the shampoo course when the vehicle to be washed 70 is a two-seater compact car or the like having a shorter vehicle length than a light vehicle. Each device of FIGS. 10 (a) to 10 (g) is the same as the above-described devices of FIGS. 8 (a) to 8 (g).

When the length of the vehicle to be washed 70 is shorter than that of the light vehicle, the time t20 at which the cleaning by the rotating brush ends on the first return path B1 is earlier than that of the light vehicle shown in FIG. Therefore, the washing water is injected from the injection unit 51 in a time T11 shorter than the time T1 (see FIG. 9), and the washing water is injected from the injection unit 52 in a time T12 shorter than the time T2 (see FIG. 9). As a result, the injection time T0 of the bottom surface cleaning device 50 becomes T11 + T12.

The injection time T0 corresponds to the time from the time t10 to the time t20, and the cleaning by the bottom surface cleaning device 50 is completed when the cleaning by the rotating brush is completed. The time T11 and the time T12 may be set so that the cleaning by the bottom surface cleaning device 50 is completed before the cleaning by the rotary brush is completed.

When the cleaning with the rotating brush is completed at time t20, the process shifts to the second outward path A2 and the blower 20 is driven. By driving the blower 20, air is blown from the top blower nozzle 21 and the side blower nozzle 22, and the vehicle to be washed 70 is dried.

Therefore, it is possible to prevent the washing water by the bottom surface cleaning device 50 from being scattered on the dried vehicle body surface of the vehicle to be washed 70, which is dried in order from the front portion due to the movement of the car wash machine main body 2. Further, since the high-pressure pump 35 and the blower 20 that consume a large amount of electric power are not driven at the same time, it is possible to prevent a shortage of electric capacity in a car wash place or a gas station where the car wash machine 1 is installed.

Next, FIG. 11 shows a time chart of the washing course for the large vehicle to be washed 70. Each device of FIGS. 11 (a) to 11 (g) is the same as the above-described devices of FIGS. 8 (a) to 8 (g). In the water washing course, the washing water of tap water is ejected from the washing nozzles 11 and 12 on the first outbound route A1, and the top brush 5 and the side brush 6 following the washing nozzles 11 and 12 are rotationally driven.

In the first return path B1, the cleaning water of tap water is ejected from the cleaning nozzle 13, and the top brush 5 and the side brush 6 following the cleaning nozzle 13 are continuously rotationally driven. In addition, cleaning is performed by the bottom surface cleaning device 50. At this time, since the vehicle body surface of the vehicle to be washed 70 is washed with water on the first outward route A1, the car wash machine main body 2 moves at a moving speed (for example, 8 m / min) higher than that of the first return route B1 of the shampoo course.

As a result, the time t20 at which the cleaning with the rotating brush ends on the first return path B1 becomes earlier than that of the shampoo course shown in FIG. Therefore, the washing water is injected from the injection unit 51 in a time T11 shorter than the time T1 (see FIG. 8), and the washing water is injected from the injection unit 52 in a time T12 shorter than the time T2 (see FIG. 8). Further, the cleaning water is injected from the injection unit 53 at a time T13 shorter than the time T3 (see FIG. 8), and the washing water is injected from the injection unit 54 at a time T14 shorter than the time T4 (see FIG. 8). As a result, the injection time T0 of the bottom surface cleaning device 50 becomes T11 + T12 + T13 + T14.

The injection time T0 corresponds to the time from the time t10 to the time t20, and the cleaning by the bottom surface cleaning device 50 is completed when the cleaning by the rotating brush is completed. The time T11 to time T14 may be set so that the cleaning by the bottom surface cleaning device 50 is completed before the cleaning by the rotary brush is completed.

When the cleaning with the rotating brush is completed at time t20, the process shifts to the second outward path A2 and the blower 20 is driven. By driving the blower 20, air is blown from the top blower nozzle 21 and the side blower nozzle 22, and the vehicle to be cleaned 70 is dried.

Therefore, similarly to the above, it is possible to prevent the cleaning water by the bottom surface cleaning device 50 from being scattered on the dried vehicle body. In addition, it is possible to prevent a shortage of electric capacity in a car wash or a gas station.

According to the present embodiment, the injection time T0 of the bottom surface cleaning device 50 is changed according to the end time of cleaning with the rotary brush, and the cleaning by the bottom surface cleaning device 50 is completed before the end of cleaning with the rotary brush or at the end of cleaning. As a result, it is possible to prevent the washing water from being scattered on the vehicle body surface of the dried vehicle 70 to be washed. Therefore, the finished state of the car wash can be improved. Further, since the high-pressure pumps 35 connected to the injection nozzles 51a to 54a and the blower 20 connected to the blower nozzles are not driven at the same time, it is possible to prevent a shortage of electric capacity at the installation location.

Further, the injection time T0 is derived based on the length of the vehicle to be washed 70 and the moving speed of the car wash machine main body 2 detected by the shape sensor 9. As a result, it is possible to easily realize a car wash machine that finishes cleaning by the bottom surface cleaning device 50 before or at the end of cleaning with the rotary brush.

Further, since the moving stroke of the car wash machine main body is changed according to the vehicle length of the vehicle to be washed 70 detected by the shape sensor 9, the car wash time can be shortened. Further, after the washing with the rotating brush is completed, the car wash machine main body 2 is inverted at the stroke end to dry the car to be washed 70. Therefore, it is possible to prevent the cleaning water from being scattered when cleaning with the rotating brush on the dried vehicle body surface.

Further, based on the detection result of the shape sensor 9, the injection units 51 to 54 that inject the cleaning water from the plurality of injection units 51 to 54 are selected according to the vehicle length of the vehicle to be cleaned 70. As a result, the injection of the washing water behind the vehicle 70 to be washed is stopped, and the scattering of the washing water with respect to the periphery of the car wash machine 1 can be reduced.

Further, since the moving speed of the car wash machine main body 2 of the water washing course is faster than that of the shampoo course, the car washing time can be shortened. At this time, the injection time T0 can be varied to improve the finished state of the car wash and improve the convenience of the car wash machine 1.

In the present embodiment, the injection of the injection time T0 may be performed from the plurality of injection units 51 to 54 selected according to the vehicle length at the time t10. As a result, the injection speed of the cleaning water is reduced, but each region on the lower surface of the vehicle to be cleaned 70 is cleaned at the injection time T0.

Further, regardless of the length of the vehicle to be cleaned 70, injection may be performed from the injection units 51 to 54 at time t10 with an injection time T0. At this time, the bottom surface cleaning device 50 may be formed by a pair of water passage pipes 55 by connecting the injection units 51 to 54.

<Second Embodiment>
Next, the car wash machine 1 of the second embodiment will be described. The car wash machine 1 of the present embodiment has a different cleaning time from the first embodiment by the injection units 51 to 54 of the bottom surface cleaning device 50. Other parts are the same as those in the first embodiment.

FIG. 12 shows a time chart of the shampoo course for the large vehicle to be washed 70. Each device of FIGS. 12 (a) to 12 (g) is the same as the above-described devices of FIGS. 8 (a) to 8 (g).

The injection unit 51 and the injection unit 52 of the bottom surface cleaning device 50 inject cleaning water regardless of the length of the vehicle to be cleaned 70. Therefore, in the first outbound route A1 before the vehicle length is detected by the shape sensor 9, the cleaning water is injected from the injection unit 51 and the injection unit 52 in order at time T1 and T2. That is, the cleaning water is injected from the injection unit 51 at the time t0 when the first outward path A1 is started, and the cleaning water is injected from the injection unit 52 at the time t2.

Then, on the first return path B1 after the vehicle length is detected by the shape sensor 9, the cleaning water is injected from the injection unit 53 and the injection unit 54 in order at time T3 and T4. That is, the cleaning water is injected from the injection unit 53 at the time t10 when the first return path B1 is started, and the cleaning water is injected from the injection unit 54 at the time t14. The injection time T0 of the bottom surface cleaning device 50 is T1 + T2 + T3 + T4. As a result, the time T1 to T4 of each injection unit 51 to 54 can be made longer than that of the first embodiment.

FIG. 13 shows a time chart of the washing course for the large vehicle to be washed 70. Each device of FIGS. 13 (a) to 13 (g) is the same as the above-described devices of FIGS. 8 (a) to 8 (g). In the same manner as described above, the cleaning water is injected from the injection unit 51 and the injection unit 52 in order at time T1 and T2 on the first outbound route A1 before the vehicle length is detected by the shape sensor 9.

Then, on the first return path B1 after the vehicle length is detected by the shape sensor 9, the injection unit 53 and the injection unit 54 are switched in this order to inject the cleaning water. At this time, the car wash machine main body 2 moves at a moving speed higher than that of the first return route B1 of the shampoo course. Therefore, the washing water is injected from the injection unit 53 in a time T13 shorter than the time T3 (see FIG. 12), and the washing water is injected from the injection unit 54 in a time T14 shorter than the time T4 (see FIG. 12). As a result, the injection time T0 of the bottom surface cleaning device 50 becomes T1 + T2 + T13 + T14.

The sum of the time T13 and the time T14 corresponds to the time from the time t10 to the time t20, and the cleaning by the bottom surface cleaning device 50 is completed when the cleaning by the rotating brush is completed. The time T13 and the time T14 may be set so that the cleaning by the bottom surface cleaning device 50 is completed before the cleaning by the rotary brush is completed.

When the cleaning with the rotating brush is completed at time t20, the process shifts to the second outward path A2 and the blower 20 is driven. As a result, the vehicle to be washed 70 is dried.

Since the moving stroke of the car wash machine main body 2 is shorter than that of the small or medium-sized vehicle to be washed 70, the washing by the injection unit 51 and the injection unit 52 may not be completed on the first outbound route A1. In this case, cleaning by the injection unit 51 or the injection unit 52 may be continuously performed on the first return path B1.

According to this embodiment, the same effect as that of the first embodiment can be obtained. Further, in order to inject the washing water from the front injection unit 51 and the injection unit 52 adjacent to the rear of the injection unit 51 on the first outward path A1, the time T1 to T4, T13, and T14 of each injection unit 51 to 54 are lengthened. be able to. Therefore, the cleaning power of the bottom surface cleaning device 50 can be improved.

In the first and second embodiments, the bottom surface cleaning device 50 is formed by a plurality of injection portions shorter in the front-rear direction than the car wash machine main body 2, and the cleaning water is switched to the injection portions covered in order by the moving car wash machine main body 2. It may be sprayed. As a result, the washing water scattered around the bottom surface cleaning device 50 can be shielded by the car wash machine main body 2.

At this time, it is more desirable that the length of each injection portion in the front-rear direction is 1/2 or less of the length in the front-rear direction of the car wash machine main body 2. As a result, when the car wash machine main body 2 comes out of one injection portion, the adjacent injection portion is covered, so that the injection stop period is not formed, and the cleaning power of the bottom surface cleaning device 50 can be prevented from being lowered.

According to the present invention, it can be used in a car wash machine provided with a bottom surface cleaning device for cleaning the bottom surface of the vehicle to be cleaned.
