Japanese Patent Laid-Open No. 06-171476

  However, according to the conventional car wash machine, since the rear surface of the vehicle to be cleaned is cleaned by the side brush arranged in front of the top brush (opposite the entrance surface), the car wash machine main body is located behind the vehicle to be cleaned. You need a lot of space to move around. That is, at least a space having a length obtained by adding the radius of the side brush, the distance between the centers of the side brush and the top brush, and the radius of the top brush is required behind the vehicle to be cleaned having the maximum vehicle length. For this reason, there existed a problem that the front-rear stroke of the car wash machine body becomes longer and the installation space of the car wash machine becomes larger.

  An object of the present invention is to provide a car wash machine capable of saving the installation space.

  In order to achieve the above object, the present invention relates to a car wash machine body that moves back and forth with respect to a vehicle to be washed, a pair of left and right first side brushes arranged in the car wash machine body, and the first side brush. A second side brush disposed on the entry side of the vehicle to be cleaned, and a top brush disposed between the first side brush and the second side brush for cleaning the upper surface of the vehicle to be cleaned. The front side of both sides of the vehicle to be cleaned and the front surface of the vehicle to be cleaned are cleaned by the first side brush, and the rear part of both sides of the vehicle to be cleaned and the rear surface of the vehicle to be cleaned are cleaned by the second side brush. When the second side brush cleans the rear surface of the vehicle to be cleaned, the second side brush advances from one end to the other end in the left-right direction of the rear surface of the vehicle to be cleaned. Sliding on the vehicle to be cleaned It rotates in a first rotational direction that, characterized in that it rotates in a second rotational direction opposite the direction of the first rotational direction between the central portion of the rear surface of the other end.

  According to the present invention, in the car wash machine configured as described above, when the second side brush cleans one side of the vehicle to be cleaned, the second side brush travels behind the vehicle to be cleaned and rotates in the first rotation direction. When cleaning, the vehicle travels forward of the vehicle to be cleaned and rotates in the first rotation direction.

  In the car wash machine configured as described above, the second side brush rotates at a lower speed than at the time of washing at the start of the car wash.

  In the car wash machine configured as described above, the second side brush rotates at a lower speed than during washing in a predetermined period after the car wash is completed.

  In the car wash machine having the above-described configuration, the second side brush is made of a material or a color different from that of the first side brush.

  Further, the present invention is characterized in that in the car wash machine having the above-described configuration, a blower nozzle is provided between the first side brush and the second side brush to dry the vehicle to be cleaned.

  Further, in the car wash machine having the above-described configuration, the car wash machine main body proceeds toward the front of the vehicle to be cleaned when the vehicle to be cleaned dries, and proceeds toward the rear of the vehicle to be cleaned at the end of drying, After the second rotating brush is disposed behind the vehicle to be cleaned, the second rotating brush moves in the left-right direction and is disposed on the passenger seat side of the vehicle to be cleaned.

  According to the present invention, in the car wash machine having the above-described configuration, an operation unit for performing an input operation is provided, and the second side brush is arranged on the passenger seat side of the vehicle to be cleaned at the start of the car wash by an input setting of the operation unit. It is characterized by.

  According to the present invention, the top brush is disposed between the pair of first side brushes and one second side brush disposed on the entry side of the vehicle to be cleaned with respect to the first side brush. Further, the front portions of both side surfaces of the vehicle to be cleaned and the front surface of the vehicle to be cleaned are cleaned by the first side brush. The rear portions of both side surfaces of the vehicle to be cleaned and the rear surface of the vehicle to be cleaned are cleaned by the second side brush. For this reason, the distance which a car wash machine main body protrudes behind a to-be-washed vehicle can be made small. Thereby, the front-rear stroke of the car wash machine body can be shortened, and the space for installing the car wash machine can be saved.

  Further, when the second side brush cleans the rear surface of the vehicle to be cleaned, the second side brush advances from one end in the left-right direction to the other end of the rear surface of the vehicle to be cleaned. And it rotates in the 1st rotation direction which slides on a to-be-cleaned vehicle in the direction opposite to the advancing direction between one end of a rear surface, and a center part. Moreover, it rotates in the 2nd rotation direction opposite to a 1st rotation direction between the center part of a rear surface, and an other end. For this reason, when the rear wiper is provided in the vehicle to be cleaned, the side brush slides from the support shaft of the rear wiper toward the open end and presses the rear wiper against the rear surface of the vehicle to be cleaned. As a result, it is possible to prevent the rear wiper from being damaged by being peeled off from the rear surface of the vehicle to be cleaned by the side brush that rotates the open end of the rear wiper.

The first and second detergent nozzles 12 and 15 are respectively arranged on the entrance surface 1a side and the exit surface 1b side of the car wash machine main body 1, and spray detergent onto the vehicle to be cleaned CA. The water repellent coating nozzle 14 and the wax nozzle 16 are arranged on the exit surface 1 b side of the car wash machine body 1. The water repellent coating nozzle 14 injects a water repellent coating agent liquid onto the vehicle CA to be cleaned. The wax nozzle 16 injects liquid wax to the vehicle CA to be cleaned.

  A water tank 70 is provided in one stand part 90. The water tank 70 is connected to the distribution piping part 28 via piping (not shown). The water tank 70 is formed smaller in the left-right direction than in the front-rear direction, and is stored in the stand unit 90. For example, about 110 liters of washing water is stored in the water tank 70.

  A vehicle detection sensor 9 is provided on the entrance surface 1 a side of the stand unit 90. The vehicle detection sensor 9 includes a photoelectric sensor having a light emitting unit and a light receiving unit, an ultrasonic sensor, and the like, and detects the length and outer shape of the vehicle CA to be cleaned entering the car wash machine main body 1.

  The car wash machine main body 1 is provided with a blower 20 that generates an air flow to dry the vehicle to be cleaned CA. The blower 20 is connected to a plurality of blowing nozzles (drying units) including a side blowing nozzle 22 and a top blowing nozzle 21. The side blowing nozzles 22 are respectively provided on both stand portions 90 and blow air toward the side surface of the vehicle to be cleaned CA. The top blowing nozzle 21 is provided in the ceiling portion 91 and blows air toward the upper surface of the vehicle CA to be cleaned.

  The top blowing nozzle 21 is disposed closer to the entrance surface 1 a of the car wash machine body 1 than the side blowing nozzle 22. Further, the top blowing nozzle 21 and the side blowing nozzle 22 are arranged between a top brush 4 and a side brush 30 described later.

  The car wash machine body 1 has a plurality of rotations comprising a top brush 4, a side brush 5 (first side brush), a rocker brush 6 and a side brush 30 (second side brush) that slide on and brush the vehicle CA to be cleaned. A brush is provided.

  Side brushes 5 are provided in a pair of left and right on the exit surface 1 b side of the car wash machine body 1. Further, the side brush 5 has a rotating shaft (not shown) arranged in the vertical direction, and cleans the cleaning area T1 (see FIG. 9) on the front surface of the vehicle CA to be cleaned and the front portion of the side surface of the vehicle CA to be cleaned.

  The top brush 4 is disposed on the side of the entrance surface 1 a of the car wash body 1 with respect to the side brush 5. Moreover, the top brush 4 arranges a rotating shaft (not shown) in the horizontal direction and moves up and down along the upper surface of the vehicle CA to be cleaned, thereby cleaning the upper surface of the vehicle CA to be cleaned. The rocker brush 6 is disposed between the side brush 5 and the top brush 4, and a rotating shaft (not shown) is disposed in the vertical direction to clean the lower portions of both side surfaces of the vehicle CA to be cleaned.

  The side brush 30 is arranged on the opposite side of the side brush 5 with respect to the top brush 4, and one side brush 30 is provided outside the entrance surface 1 a of the car wash machine body 1. Further, the side brush 30 has a rotating shaft (shaft 30a) arranged in the vertical direction, and cleans the rear cleaning region T2 (see FIG. 10) on the side surface of the vehicle CA to be cleaned and the rear surface of the vehicle CA to be cleaned.

  Each rotating brush has a plurality of cleaning materials such as cloth and sponge attached to the peripheral surface of the shaft forming the rotating shaft. For this reason, the rocker brush 6, the side brush 5, and the side brush 30 with the rotation shafts arranged in the vertical direction have a small diameter because the cleaning material hangs down when the rotation is stopped, and have a large diameter because the cleaning material spreads by the centrifugal force during the rotation. The side brush 30 is made of a material or color different from that of the side brush 5.

  FIG. 3 shows a schematic front view of the car wash machine body 1. A rail 26 (guide portion) extending in the left-right direction is provided in the collar portion 40 (see FIG. 2). The side brush 30 is held by a holding portion 35 that runs on the rail 26. Thereby, the side brush 30 is arranged to be movable in the left-right direction.

  FIG. 4 shows a front view of the upper part of the side brush 30. The holding part 35 is formed of a plurality of metal plates, and surrounds the front and rear surfaces of the rail 26 with a pair of opposing walls 35a that face front and rear. The holding portion 35 is provided with a drive wheel 27 that rolls on the rail 26, and a driven roller 34a to a driven roller 34e.

  The driving wheel 27 is axially supported by the holding portion 35 with its axial direction being horizontally arranged. The driving wheel 27 rolls on the upper surface 26 a of the rail 26 by driving of a moving motor 36 attached to the holding portion 35. The upper surface 26a of the rail 26 is inclined at the front and rear ends, and the peripheral surface of the drive wheel 27 is formed in a V shape along the front and rear inclined surfaces of the upper surface 26a. Thereby, the drive wheel 27 can roll on the upper surface 26a of the rail 26 stably.

  The driven roller 34a is axially supported by the holding portion 35 with the axial direction inclined with respect to the horizontal, and a pair of front and rear rollers are provided along the front and rear inclined surfaces of the upper surface 26a. The driven rollers 34 b and 34 c are horizontally supported in the axial direction and are pivotally supported by the pivotal support portion 25, and roll on the lower surface 26 b of the rail 26. The driven rollers 34d and 34e are axially supported by the holding portion 35 with their axial directions being vertically arranged, and roll on the side surface 26c of the rail 26.

  A shaft support portion 25 that supports the side brush 30 is provided on the facing wall 35a. A shaft 30a that forms a rotation axis of the side brush 30 is inserted into a hollow rod 30b having a rectangular horizontal cross section, and is rotatably supported by a bearing (not shown) disposed in the rod 30b. The shaft 30a is connected to a rotation motor (not shown) installed in the holding unit 35, and the side brush 30 rotates around a rotation axis extending vertically by driving the rotation motor.

  Further, a shaft portion 30d projects from the front and rear surfaces of the rod 30b, and the shaft support portion 25 is provided with a bearing 25a that fits the shaft portion 30d. Thereby, the holding | maintenance part 35 hold | maintains the side brush 30 so that it can incline in the left-right direction centering on the axial part 30d.

  The shaft support 25 is provided with an inclination sensor 25b and an inclination sensor 25c each including a proximity switch above and below the shaft 30d. On the rod 30b, an opposing member 39b is disposed above the inclination sensor 25b, and an opposing member 39c is disposed below the inclination sensor 25c.

  The opposing member 39b and the opposing member 39c are opposed to the inclination sensor 25b and the inclination sensor 25c, respectively, and detect the amount of inclination of the side brush 30. The side brush 30 that moves in the left-right direction by driving the moving motor 36 is inclined when it comes into contact with the vehicle CA to be cleaned. And if the inclination sensor 25b opposes the opposing member 39b, the movement motor 36 will be stopped and the side brush 30 will be distribute | arranged to desired inclination amount at the time of washing | cleaning. Further, when the inclination sensor 25c faces the facing member 39c, the moving motor 36 is stopped, and the side brush 30 is disposed at a desired inclination amount during cleaning.

  That is, when the right side surface of the vehicle CA to be cleaned is cleaned, the inclination sensor 25b detects that the side brush 30 has reached a desired inclination amount facing the opposing member 39b in the drawing. When cleaning the left side of the vehicle CA to be cleaned, the inclination sensor 25c detects that the side brush 30 has reached a desired inclination amount facing the opposing member 39c in the drawing.

  Alternatively, the counter member may be newly increased on the right side of the counter members 39b and 39c, and an abnormality in the inclination amount of the side brush 30 may be detected by the increased counter member. When an abnormality is detected, the side brush 30 can be retreated from the vehicle to be cleaned CA by the moving motor 36.

  The holding portion 35 is provided with a double-acting air cylinder 32 disposed above the shaft portion 30d. The air cylinder 32 has a cylindrical cylinder tube 32b and a cylinder rod 32a, and the tip of the cylinder rod 32a is rotatably connected to the upper end of the rod 30b. A pipe 33 is connected to the front end and the rear end of the cylinder tube 32 b, and air is supplied through one pipe 33. Accordingly, the cylinder rod 32a is changed between an extended state and a contracted state, and the air brush 32 biases the side brush 30 in the circumferential direction of the shaft portion 30d.

  That is, the cylinder rod 32a extends during the cleaning of the left side surface of the vehicle CA to be cleaned, and the side brush 30 that contacts the vehicle CA to be cleaned inclines clockwise in the drawing against the urging force of the air cylinder 32. Further, when the right side surface of the vehicle CA to be cleaned is cleaned, the cylinder rod 32a is contracted, and the side brush 30 that contacts the vehicle CA to be cleaned inclines counterclockwise in the drawing against the urging force of the air cylinder 32.

  Thus, the side brush 30 can be urged in both the left and right directions by the single air cylinder 32. Further, when the side brush 30 is urged in the left and right directions by the two coil springs, the elastic force due to expansion and contraction from the free length of the coil spring to the neutral position is canceled out. For this reason, the urging force with respect to the side brush 30 inclined from the neutral position becomes small, and it is difficult to obtain a large urging force.

  On the other hand, the air cylinder 32 can obtain a large urging force in both the left and right directions with respect to the side brush 30 by switching the air supply direction. Therefore, it is possible to easily realize the side brush 30 having a large pressing force against both side surfaces of the vehicle CA to be cleaned and a large cleaning power. The air cylinder 32 may be a single-acting type, but if it is a double-acting type, the urging force in both the left and right directions is obtained by air pressure. For this reason, even if the inclination amount of the side brush 30 fluctuates, the urging force can be stabilized, and the pressing force of the side brush 30 against the vehicle CA to be cleaned can be made uniform.

  The side brush 5 is also arranged to be movable in the left-right direction with the same configuration. At this time, since the pair of side brushes 5 are arranged on the left and right, the inclination sensors 25b and 25c detect inclination in one direction. In addition, a coil spring that biases the side brush 5 in one direction of inclination is provided instead of the air cylinder 32.

  The shaft 30a of the side brush 30 is provided so as to be removable from the rod 30b. Moreover, the collar part 40 is provided in the ceiling part 91 so that rotation is possible by the axial part 40a (refer FIG. 1). For this reason, as shown in FIG. 5, when the side brush 30 is removed and the collar part 40 is rotated downward, the front-rear width of the car wash machine main body 1 can be reduced. Thereby, the car wash machine main body 1 can be placed on the loading platform by arranging the front and rear direction of the car wash machine main body 1 in the left and right direction of the loading platform of the transport vehicle when the car wash machine main body 1 is transported.

  6 and 7 show a top view and a perspective view of the right front portion of the car wash machine body 1. The car wash machine main body 1 is provided with a flying cover 51 that protrudes from the side end portions of both stand portions 90 to the entry side of the vehicle to be cleaned CA and extends in the vertical direction. The flying water cover 51 is formed of an acrylic plate or the like, and shields flying water of the side brush 30 that moves in the left-right direction below the collar portion 40. Thereby, scattering of the washing water by the side brush 30 can be reduced.

  The right stand 90 is provided with a support 8a that protrudes along the flying water cover 51 toward the approach side of the vehicle CA to be cleaned, and an operation panel 8 (operation) is disposed at the tip of the support 8a. The operation panel 8 has a plurality of operation buttons (not shown), and can perform input operations such as an instruction to start car wash and an instruction to stop car wash.

  The operation panel 8 is inclined toward the entrance side of the vehicle to be cleaned CA toward the center in the left-right direction of the car wash machine body 1. Accordingly, the front and rear width of the car wash machine main body 1 can be reduced, and interference between the side brush 30 disposed on the right end portion and the operation panel 8 can be avoided to ensure a large installation area of the operation buttons on the operation panel 8. Can do.

  In the car wash machine WA having the above configuration, a predetermined car wash setting is performed from the remote panel 7 and the vehicle to be cleaned CA is stopped at a predetermined position. At this time, by operating the remote panel 7, the side brush 30 is disposed at the initial position Y1 (see FIG. 8) on the passenger seat side (usually the left side) of the vehicle CA to be cleaned. As a result, the driver can easily get off before starting the car wash. Alternatively, the driver may get off before entering the car wash machine main body 1 and set using the operation panel 8.

  When the to-be-washed vehicle CA stops at a predetermined position, the car wash machine main body 1 moves in the front-rear direction from the car wash start position U1 (see FIG. 8), and the car wash is performed. 8-10 is a top view which shows the state at the time of washing | cleaning by the car-washing machine main body 1. FIG.

  When the car wash is started, as shown by an arrow D1 in FIG. 8, the car wash machine body 1 starts moving from the car wash start position U1 toward the rear of the vehicle to be cleaned CA. As the car wash machine body 1 moves, the vehicle detection sensor 9 detects the shape of the vehicle to be cleaned CA.

  At this time, the side brush 30 rotates at a lower speed than when the side brush 30 is cleaned. Since the side brush 30 protrudes from the stand unit 90 toward the approach side of the vehicle CA to be cleaned, there is a possibility that a person exists near the side brush 30. For this reason, there is a risk of injury if the side brush 30 that has stopped rotating is rotated at high speed for cleaning. Therefore, by rotating the side brush 30 at a low speed before cleaning, it is possible to recognize in advance that high-speed rotation is performed and to prevent danger.

  The top brush 4 moves up and down along the shape of the vehicle to be cleaned CA detected by the vehicle detection sensor 9. Thereby, the upper surface of the to-be-cleaned vehicle CA is cleaned.

  When the side brush 5 is disposed at the front end of the vehicle CA to be cleaned detected by the vehicle detection sensor 9, the car wash machine body 1 stops, and the left and right side brushes 5 rotate and move in the left-right direction. Thereby, the front surface of the vehicle CA to be cleaned is cleaned.

  When the cleaning of the front surface of the vehicle to be cleaned CA is completed, the left and right side brushes 5 are separated, and the car wash machine body 1 moves again toward the rear of the vehicle to be cleaned CA as shown in FIG. Thereby, the front part of the side surface of the vehicle CA to be cleaned is cleaned by the side brush 5.

  At this time, the side brush 5 rotates in the direction of sliding on the vehicle CA to be cleaned in the direction opposite to the traveling direction. That is, the left side brush 5 rotates in the rotation direction V1 (counterclockwise in the figure), and the right side brush 5 rotates in the rotation direction V2 (clockwise in the figure).

  As shown in the figure, when the top brush 4 is cleaned to the rear end of the vehicle CA to be cleaned, the car wash machine main body 1 is stopped and the top brush 4 and the side brush 5 are stopped. Thereby, the cleaning of the upper surface of the vehicle CA to be cleaned is completed, and the cleaning of the front cleaning area T1 on both side surfaces is completed.

  At this time, if the distance between the centers of the top brush 4 and the side brush 30 is L, the radius of the top brush 4 is R1, and the radius of the side brush 30 is R2, the car wash machine body 1 protrudes behind the vehicle CA to be cleaned. The distance W is about L + R2-R1.

  Next, as shown in FIG. 10, when the car washer main body 1 is moved toward the front of the vehicle to be cleaned CA and the side brush 30 is disposed at the end of the cleaning region T1, the car washer main body 1 is stopped. Then, the side brush 30 moves along the vehicle to be cleaned CA as indicated by an arrow E1, and cleans the cleaning area T2 at the rear of both side surfaces of the vehicle to be cleaned CA and the rear surface of the vehicle to be cleaned CA.

  That is, the car wash machine body 1 moves toward the rear of the vehicle CA to be cleaned, and the cleaning region T2 on the left side surface of the vehicle CA to be cleaned is cleaned by the side brush 30. Next, the car wash machine main body 1 stops, the side brush 30 moves in the left-right direction, and the rear surface of the vehicle CA to be cleaned is cleaned. Next, the car wash machine main body 1 moves toward the front of the vehicle to be cleaned CA, and the cleaning region T2 on the right side surface of the vehicle to be cleaned CA is cleaned by the side brush 30.

  FIGS. 11-14 is a front view which shows the washing | cleaning state by the side brush 30 at this time. When the cleaning by the side brush 30 is started, the air cylinder 32 is supplied with air in the direction in which the cylinder rod 32a extends. Then, as shown in FIG. 11, the holding unit 35 is guided and moved in the right direction from the left end of the rail 26 by the drive of the movement motor 36, and the side brush 30 comes into contact with the left side surface of the vehicle CA to be cleaned.

  Thereby, the side brush 30 inclines in the left-right direction against the urging force of the air cylinder 32, and the movement motor 36 is stopped when the side brush 30 is disposed at a predetermined inclination amount by the detection of the inclination sensor 25b. At this time, the side brush 30 rotates in the rotation direction V3 (first rotation direction, see FIG. 10) sliding on the vehicle CA to be cleaned in the direction opposite to the traveling direction, and cleans the left side surface of the vehicle CA to be cleaned.

  When the side brush 30 is disposed behind the vehicle to be cleaned CA, the car wash machine main body 1 stops moving. At this time, since the side brush 30 is released from the pressing force from the side surface of the vehicle CA to be cleaned, the cylinder rod 32a extends. For this reason, as shown in FIG. 12, the side brush 30 inclines so that a lower end faces the right side. Then, the side brush 30 is moved to the right by the drive of the movement motor 36, and the rear surface of the vehicle CA to be cleaned is cleaned. At this time, the side brush 30 rotates in the rotation direction V3.

  When the side brush 30 reaches the substantially central portion P1 on the rear surface of the vehicle CA to be cleaned, air is supplied to the air cylinder 32 in a direction in which the cylinder rod 32a contracts. For this reason, as shown in FIG. 13, the side brush 30 inclines so that a lower end faces the left side. The air cylinder 32 may supply air in the direction in which the cylinder rod 32a contracts at the end of cleaning of the rear surface of the vehicle CA to be cleaned.

  Further, the rotation motor of the side brush 30 is reversed, and the side brush 30 rotates in the rotation direction V4 (second rotation direction, see FIG. 10) opposite to the rotation direction V3. Thus, the remaining rear surface of the vehicle CA to be cleaned is cleaned by the side brush 30 that rotates in the rotation direction V4.

  The side brush 30 rotates on the left half of the rear surface of the vehicle to be cleaned CA in the rotation direction V3 that slides on the vehicle to be cleaned CA in the direction opposite to the traveling direction, and slides on the vehicle to be cleaned in the traveling direction on the right half. Rotate in the rotation direction V4. For this reason, when the rear wiper is provided in the vehicle CA to be cleaned, the side brush 30 slides from the support shaft of the rear wiper toward the open end and presses the rear wiper against the rear surface of the vehicle CA to be cleaned. Thereby, it is possible to prevent the rear wiper from being damaged by being peeled off from the rear surface of the vehicle CA to be cleaned by the side brush 30 in which the open end of the rear wiper rotates.

  The side brush 30 moves to the right end of the rail 26 when cleaning of the rear surface of the vehicle CA to be cleaned is completed. At this time, the rotation motor of the side brush 30 is reversed, and the side brush 30 rotates in the rotation direction V3 (see FIG. 10).

  Further, as shown in FIG. 14, the holding portion 35 is guided and moved leftward from the right end of the rail 26 by driving of the movement motor 36, and the side brush 30 comes into contact with the right side surface of the vehicle CA to be cleaned. Thereby, the side brush 30 inclines in the left-right direction against the urging force of the air cylinder 32, and the movement motor 36 is stopped when the side brush 30 is disposed at a predetermined inclination amount by the detection of the inclination sensor 25b. Then, the car wash machine main body 1 moves in front of the vehicle CA to be cleaned, and the side brush 30 cleans the cleaning area T2 on the right side surface of the vehicle CA to be cleaned.

  Although the start end of the cleaning region T2 and the end of the cleaning region T1 coincide, the start end of the cleaning region T2 may be set ahead of the end of the cleaning region T1. That is, the car wash machine body 1 may be moved forward until the side brush 30 is disposed at least at the end of the cleaning area T1 after the cleaning area T1 is cleaned.

  Alternatively, the cleaning area T2 on one side of the vehicle CA to be cleaned may be cleaned with the side brush 30 while the car wash machine body 1 moves forward after the cleaning area T1 is cleaned with the side brush 5.

  When the cleaning of the cleaning region T2 on both side surfaces by the side brush 30 is completed, the car wash machine body 1 moves toward the rear of the vehicle to be cleaned CA and is disposed at the drying start position U2 shown in FIG. At the drying start position U2, the rear surface of the vehicle CA to be cleaned is dried by the top blowing nozzle 21. When the car wash machine main body 1 arranged at the drying start position U2 moves toward the front of the vehicle to be cleaned CA as indicated by the arrow D2, the top blow nozzle 21 and the side blow nozzle 22 dry the vehicle to be cleaned CA. .

  When drying of the vehicle to be cleaned CA is finished by the top blower nozzle 21 and the side blower nozzle 22, the car wash machine main body 1 moves to the rear of the vehicle to be cleaned CA, and the vehicle to be cleaned CA moves forward and exits. At this time, when it is detected that the side brush 30 is arranged behind the rear end of the vehicle CA to be cleaned, the side brush 30 moves in the left-right direction and returns to the initial position Y1 (see FIG. 8). At this time, when the next vehicle to be cleaned CA is set to be washed, the initial position Y1 is varied according to the position of the passenger seat of the vehicle to be cleaned CA.

  Thereby, the movement of the car wash machine main body 1 in the front-rear direction and the movement of the side brush 30 in the left-right direction are simultaneously performed, and the car wash time can be shortened. When the car wash machine body 1 to be described later returns to the car wash start position U1, the side brush 30 may move in the left-right direction and return to the initial position Y1 (see FIG. 8).

  When it is confirmed that the vehicle to be cleaned CA has exited, the car wash machine main body 1 returns to the car wash start position U1 and the car wash ends. Then, the side brush 30 is rotated in advance at a lower speed than at the time of washing and then dehydrated during a predetermined period after the car wash is completed. Since it rotates at low speed, it is possible to prevent danger by recognizing in advance that high-speed rotation is performed. Moreover, the moisture of the side brush 30 can be removed to prevent the side brush 30 from freezing in winter.

  According to the present embodiment, the top is between a pair of side brushes 5 (first side brush) and one side brush 30 (second side brush) disposed on the entry side of the vehicle CA to be cleaned with respect to the side brush 5. A brush 4 is arranged. Further, the side brush 5 cleans the front cleaning area T1 on both sides of the vehicle to be cleaned CA and the front surface of the vehicle to be cleaned CA. The side brush 30 cleans the rear cleaning area T2 on both side surfaces of the vehicle CA to be cleaned and the rear surface of the vehicle CA to be cleaned. For this reason, the distance W by which the car washer main body 1 protrudes rearward of the vehicle to be cleaned CA can be reduced. Thereby, the front-rear stroke of the car wash machine body 1 can be shortened, and the installation space of the car wash machine WA can be saved.

  Further, when the side brush 30 cleans the rear surface of the vehicle CA to be cleaned, the side brush 30 advances from one end in the left-right direction to the other end of the rear surface of the vehicle CA to be cleaned. And it rotates in the rotation direction V3 (1st rotation direction) which slides on the to-be-cleaned vehicle CA in the direction opposite to the advancing direction between one end of the rear surface and the center part P1. Moreover, it rotates by V4 (2nd rotation direction) opposite to V3 (1st rotation direction) between the center part P1 of a rear surface, and the other end. For this reason, when the rear wiper is provided in the vehicle CA to be cleaned, the side brush 30 slides from the support shaft of the rear wiper toward the open end and presses the rear wiper against the rear surface of the vehicle CA to be cleaned. Thereby, it is possible to prevent the rear wiper from being damaged by being peeled off from the rear surface of the vehicle CA to be cleaned by the side brush 30 in which the open end of the rear wiper rotates.

  Further, when the side brush 30 cleans one side of the vehicle CA to be cleaned, the side brush 30 travels behind the vehicle CA to be cleaned and rotates in the rotation direction V3, and proceeds to the front of the vehicle CA to be cleaned when cleaning the other side. And rotate in the rotation direction V3. As a result, the contact time between the side brush 30 and the vehicle to be cleaned CA can be increased, and the cleaning power can be improved.

  In addition, the side brush 30 rotates at a lower speed than at the time of washing when the car wash starts. Thereby, it can be recognized in advance that high-speed rotation is performed, and danger can be prevented.

  In addition, the side brush 30 rotates at a lower speed than during washing in a predetermined period after the car wash is completed. Thereby, it can be recognized in advance that high-speed rotation is performed, and danger can be prevented. Moreover, the moisture of the side brush 30 can be removed to prevent the side brush 30 from freezing in winter.

  Further, the side brush 30 is made of a material or color different from that of the side brush 5. Thereby, the side brush 30 can be appealed and a customer collection rate can be improved.
