In the drying process, the control unit 44 relatively moves the car wash machine main body 4 rearward with respect to the vehicle X, as shown in step S8-2 of FIG. Here, in the drying process, the control unit 44 controls the blower 36 to control air blowing from the top air blowing nozzle 38 or the side air blowing nozzle 40 . During the drying process, controller 44 may control the position of top blower nozzle 38 or side blower nozzle 40 . During the drying process, the control section 44 may control each arm 50 and each arm 56 to store each side brush 16 and each rocker brush 18 in each stand section 8 .

Thus, in the drying process, the car wash machine 2 dries the vehicle X by blowing off or volatilizing moisture such as water droplets adhering to the vehicle X by blowing air from each air blowing nozzle of the car washing machine main body 4.例文帳に追加The control unit 44 moves the car wash machine body 4 rearward relative to the vehicle X until the vehicle X has completely passed through the space 4S of the car wash machine body 4, and controls air blowing from each air blow nozzle. As described above, the drying process is completed, and the washing of the vehicle X by the car washing machine 2 is completed.

Although the drying process according to the present embodiment is performed by blowing air to the vehicle X while moving the car wash machine main body 4 in the rearward direction relative to the vehicle X, the drying process is not limited to this. For example, in the drying process according to the present embodiment, the control unit 44 moves the car wash machine main body 4 to the rear of the vehicle X, and then moves the car wash machine main body 4 toward the front of the vehicle X again. A blow to X may be performed.

Moreover, in the method for washing the vehicle X by the car wash machine 2 according to the present embodiment, the first washing step and the second washing step may be performed once each, but the present invention is not limited to this. For example, in the present embodiment, after the first second cleaning step, the second first cleaning step and the second cleaning step may be performed in order. The first and second washing steps for the second time may be performed in the same manner as the first and second washing steps for the first time. Furthermore, in the present embodiment, the first cleaning process and the second cleaning process may be performed three times or more.

<Summary of Embodiment 1>
In this embodiment, the control unit 44 controls each rocker brush 18 based on the control details of each side brush 16 during at least a part of the period. During this control, the position or biasing force of each rocker brush 18 with respect to the lower portion of the side surface XS when cleaning the lower portion of the side surface XS by each rocker brush 18 becomes more appropriate. Therefore, compared to the case where each rocker brush 18 is controlled using only the repulsive force between each rocker brush 18 and the vehicle X, the car wash machine 2 according to this embodiment can more appropriately can be washed.

In particular, there may be a space between the tires of the vehicle X and the wheel house below the side surface XS that is cleaned by each rocker brush 18 . In this case, the car wash machine 2 according to the present embodiment prevents the rocker brushes 18 from entering the space too much. Further, in the side rear portion XSB, there may be a structure such as a corner of the bumper of the vehicle X, which protrudes from the surroundings on the side surface XS. In this case, the car wash machine 2 according to the present embodiment can more appropriately clean portions where it is difficult to control the positions of the rocker brushes 18 during cleaning by the rocker brushes 18, as in the projecting structure.

In the present embodiment, the vehicle X is washed by at least part of the washing section of the car wash machine main body 4 during both the first period and the second period of the vehicle X washing process. Therefore, the washing of the vehicle X by the car washing machine 2 is more thorough than when washing is performed in either one of the first period and the second period.

Further, in the present embodiment, the control unit 44 controls each rocker brush 18 during the second period based on the details of control of each side brush 16 during the first period. In other words, the control unit 44 does not need to control each rocker brush 18 in the first period based on the details of control of each side brush 16 in the first period. Therefore, in the present embodiment, it is not necessary for the control section 44 to simultaneously record the control details of the side brushes 16 and control the rocker brushes 18 according to the control details during the first period. Therefore, in the present embodiment, control of each side brush 16 and each rocker brush 18 by the control section 44 becomes simpler.

In the present embodiment, the control unit 44 causes the rocker brushes 18 to clean only part of the lower portion of the side surface XS during the first period as well. As a result, the control unit 44 can cause the rocker brushes 18 to clean, even in the first period, portions of the lower portion of the side surface XS that can be adequately cleaned without strict position control. Therefore, the car wash machine 2 can thoroughly wash the portion of the lower portion of the side surface XS which is also washed by the rocker brushes 18 during the first period.

In particular, during the first period, the rocker brushes 18 wash the side surfaces XS at the same position in the longitudinal direction of the vehicle X before the side brushes 16 wash the side surfaces XS. Also, generally, the lower portion of the side surface XS of the vehicle X tends to be heavily soiled with mud and the like. Therefore, in the present embodiment, the car wash machine 2 can wash the side surface XS with the side brushes 16 after washing the lower portion of the side surface XS of the vehicle X to which dirt tends to adhere with the rocker brushes 18 in the first period. Therefore, in the present embodiment, the car wash machine 2 can reduce reattachment of dirt on the lower portion of the side surface XS to the vehicle X during the first period, and can wash the vehicle X more appropriately.

The car wash machine main body 4 according to this embodiment includes a rocker brush 18 attached to an arm 56 including a plurality of slide portions 58 that move parallel to each other. Therefore, the control unit 44 can control the position of the rocker brush 18 with respect to the car wash machine main body 4 by controlling the mutual parallel movement of the plurality of slide portions 58 .

Here, the control unit 44 can control the positions of the rocker brushes 18 in the longitudinal direction of the vehicle X by moving the car wash machine main body 4 relative to the vehicle X. As shown in FIG. In other words, in order to control the position of each rocker brush 18 with respect to the vehicle X, it is sufficient to control the distance by which each rocker brush 18 protrudes from each stand portion 8 .

In this embodiment, the car wash machine main body 4 includes an arm 56 extending in a direction substantially perpendicular to the entering direction DA of the vehicle X and in a direction substantially horizontal to the ground G. As shown in FIG. Thereby, the control of the distance by which each rocker brush 18 protrudes from the stand portion 8 by the control portion 44 can be realized by controlling the expansion and contraction of the arm 56 . In other words, the controller 44 does not need to change the angle of the arm 56 with respect to the car wash machine main body 4 in order to control the distance by which each rocker brush 18 protrudes from the stand 8 . Therefore, the car wash 2 can control the position of each rocker brush 18 with a simpler configuration.

In addition, due to the configuration of the arm 56 described above, regardless of the direction in which the car wash machine main body 4 moves relative to the vehicle X, the extending direction of the arm 56 is always substantially perpendicular to the side surface XS. Therefore, the car wash machine 2 can wash the lower portion of the side surface XS under the same conditions with each rocker brush 18 in both the first period and the second period. In particular, the car wash machine 2 can wash the lower portion of the side surface XS more appropriately between the first period and the second period without changing the extending direction of each arm 56 .

The drying process according to this embodiment may be performed by the same method as the drying process according to the previous embodiment. In particular, as shown in step S8-4 of FIG. 8, the controller 44 may control each arm 64 to store each rocker brush 18 in each stand 8 during the drying process. With the completion of the drying process, the washing of the vehicle X by the car wash machine 2 is completed.

Also in the present embodiment, the control unit 44 controls each rocker brush 18 based on the control details of each side brush 16 during at least a part of the period. Therefore, the car wash machine 2 according to the present embodiment can also use the rocker brushes 18 to more appropriately wash the lower portion of the side surface XS.

Further, in the present embodiment, cleaning of the lower portion of the side surface XS by each rocker brush 18 is stopped during the first period. Therefore, in the present embodiment, the rocker brushes 18 do not wash the lower portion of the side surface XS during the first period in which the information on the details of control of the side brushes 16 is not sufficiently obtained. Therefore, the car wash machine 2 according to the present embodiment more reliably prevents inappropriate washing by the rocker brushes 18 during the first period.

Here, in the second period of the present embodiment, in a state where each rocker brush 18 is located on the rearward side of the vehicle X relative to the shaft 66, each rocker brush 18 cleans the lower portion of the side surface XS. As a result, when the lower part of the side surface XS is washed by the rocker brushes 18 while the car wash machine main body 62 is moving forward with respect to the vehicle X, the force in the direction in which the rocker brushes 18 bite into the vehicle X is applied. Each rocker brush 18 is less likely to be caught. Therefore, the car wash machine 2 can use each rocker brush 18 to wash the lower portion of the side surface XS more appropriately.

In the present embodiment, cleaning of the lower portion of the side surface XS by each rocker brush 18 is performed only during the second period. For this reason, for example, in order to wash the lower portion of the side surface XS by the rocker brushes 18 during the first period, the control unit 44 is configured so that the rocker brushes 18 are positioned on the front side of the vehicle X relative to the shaft 66 . No control of the arm 64 is required. Therefore, each rocker brush 18 and each arm 64 may be designed to be suitable for washing the lower portion of the side surface XS by each rocker brush 18 during the second period. Control of the brush 18 becomes simpler.
