The shape sensor 9 includes a photoelectric sensor, an ultrasonic sensor, and the like, and detects a vehicle length and an outer shape of the vehicle CA to be washed entering the car wash machine main body 1. In addition, a notification unit (not shown) is provided in the car washer body 1. The notification unit includes a speaker and a display, and performs notification by voice or display.

  The car washer body 1 is provided with a drying unit for drying the vehicle CA to be cleaned and a cleaning unit for cleaning the vehicle CA to be cleaned.

  The drying section includes a blower 20 and a plurality of blowing nozzles. The blower 20 is disposed above the car washer body 1 and generates an airflow for drying the vehicle CA to be cleaned. The blowing nozzle includes a side blowing nozzle 22 and a top blowing nozzle 23. The side blowing nozzles 22 are provided on both the stand portions 90, respectively, and blow the air toward the side surface of the vehicle CA to be cleaned. The top blowing nozzle 23 is provided on the ceiling 91 and blows air toward the upper surface of the vehicle CA to be cleaned.

  The cleaning unit includes a plurality of rotating brushes and a plurality of nozzle units. The rotating brush includes a top brush 4, a side brush 5, and a rocker brush 6. The top brush 4 moves along the upper surface of the vehicle to be cleaned CA to clean the upper surface of the vehicle to be cleaned CA. The side brush 5 cleans the side surface and the rear surface of the vehicle CA to be cleaned. The rocker brush 6 cleans the lower part of both sides of the vehicle CA to be cleaned.

  The nozzle unit has a water purification nozzle 11, a water purification nozzle 13, a detergent nozzle 12, a detergent nozzle 15, a water-repellent coat nozzle 14, and a wax nozzle 16. Each nozzle unit is connected to a distribution pipe unit 31 provided in the stand unit 90 via an electromagnetic valve (not shown).

  A water storage tank 72 and a plurality of liquid storage tanks (not shown) are connected to the distribution pipe section 31 via pipes (not shown). The plurality of liquid storage tanks are stored in a tank storage unit 30 provided in the stand unit 90. Various liquid agents such as detergent and wax are stored in each liquid storage tank. The cleaning water and various liquids are distributed by the distribution pipe section 31, and the cleaning water and various liquids are supplied to the nozzle portion.

  The water purifying nozzle 11 and the water purifying nozzle 13 are disposed on the inlet surface 1a side and the outlet surface 1b side of the car washer body 1, respectively, and inject cleaning water to the vehicle CA to be cleaned. The detergent nozzle 12 and the detergent nozzle 15 are arranged on the inlet surface 1a side and the outlet surface 1b side of the car washer body 1, respectively, and inject the detergent to the vehicle CA to be washed. The water-repellent coating nozzle 14 is disposed on the exit surface 1b side of the car wash machine body 1, and injects a water-repellent coating agent to the vehicle CA to be cleaned. The wax nozzle 16 is disposed on the outlet surface 1b side of the car wash machine main body 1 and injects liquid wax to the vehicle CA to be cleaned.

  The cleaning section has an upper surface cleaning device 52 disposed on the upper surface of the ceiling section 91.

  FIG. 3 shows a schematic top view of the car washer body 1. The upper surface cleaning device 52 has a guide section 54, an arm 55, and an injection section 53. The guide portions 54 extend in the front-rear direction and are provided in a pair on the left and right sides of the ceiling surface 1c of the car wash machine body 1. The guide section 54 has a U-shaped vertical cross-section, and has an opening (not shown) extending in the front-rear direction on the inner surface facing the opening.

  The arms 55 extend in the front-rear direction and are provided as a pair of right and left arms, project from the entrance surface 1a of the car wash machine main body 1, and bend downward to be inclined. The arm 55 is provided with a roller 55b that rolls on the inner surface of the guide portion 54. The two arms 55 are connected on the outlet surface 1b side by a connecting portion 55a, and are connected on the inlet surface 1a side by a base 58 (see FIG. 3) of the injection unit 53.

  A guide motor 63 having a motor shaft having a sprocket (not shown) is disposed at one end in the front-rear direction between the guide portions 54, and a sprocket (not shown) pivotally supported by the car wash machine body 1 is provided at the other end. Be placed. The connecting portion 55a is attached to a chain (not shown) wound around both sprockets. When the guide motor 63 is driven, the arm 55 moves in the front-back direction. As a result, the injection portion 53 provided at the tip of the arm 55 extends the arm 55 from the car wash machine body 1 toward the rear of the vehicle CA to be washed, and to the standby position S1 (see FIG. 9) close to the car wash machine body 1. It moves between the end position S2 (see FIG. 10).

  The jetting section 53 is covered by a cover 57 attached to a distal end bent below the arm 55. The upper surface of the cover 57 is formed by an inclined surface 57a (see FIG. 1). This makes it difficult for snow to be deposited on the cover 57, and the arm 55 can be moved smoothly even when snow falls.

  FIG. 4 shows a front view of the injection unit 53. A swing motor 62, an ejection nozzle 59 (second ejection nozzle), and an ejection nozzle 60 (first ejection nozzle) are provided on a base 58 connecting both arms 55. The base 58 is formed in a plate shape extending in the left-right direction.

  The oscillating motor 62 is attached to the center of the base 58 in the left-right direction with the axial direction arranged in the front-rear direction. A crank 66 is attached to a shaft 62 a of the swing motor 62. The crank 66 has a rotating plate 66a mounted on the shaft portion 62a and an arm 66b rotatably supported on the periphery of the rotating plate 66a.

  A pair of injection nozzles 59 are provided at the center of the base 58 on the left and right sides, and are respectively attached to the support portions 65 (second support portions). The injection nozzle 59 is connected to the distribution pipe section 31, and the high-pressure water W1 (see FIG. 9) is injected downward from the injection port 59a. The support portion 65 is formed in an L shape, and is disposed on the base 58 so as to be rotatable around a shaft portion 65a. One end of an arm 66b of a crank 66 is rotatably connected to the upper end of the one support portion 65.

  A pair of injection nozzles 60 are provided at both left and right ends of the base 58, and are respectively attached to the support portions 64 (first support portions). The spray nozzle 60 has a plurality of spray ports 60a and is connected to the distribution pipe section 31, and the foamy liquid agent W2 is sprayed downward from the spray ports 60a. The support portion 64 is formed in an L-shape, and is disposed on the base 58 so as to be rotatable around a shaft portion 64a. Note that the shaft portion 64a and the shaft portion 65a are arranged at substantially the same height.

  The left support portion 64 is connected to the left support portion 65 by a link member 67a, and the right support portion 64 is connected to the right support portion 65 by a link member 67a. The left and right support portions 65 are connected by a link member 67b.

  When the swing motor 62 is driven, the support portions 64 and 65 swing left and right via the crank 66 and the link members 67a and 67b. Accordingly, the ejection nozzle 60 and the ejection nozzle 59 swing integrally. At this time, since the ejection port 60a of the ejection nozzle 60 and the ejection port 59a of the ejection nozzle 59 are arranged at the same position in the front-back direction, they swing within the same swing plane.

  FIG. 5 shows a front view of the left injection nozzle 60. As shown in FIG. 5, the injection nozzle 60 swings at a predetermined swing angle α within a range in which the injection port 60a faces inward with respect to the vertical direction V. For this reason, it is possible to prevent the foamed liquid agent W2 injected from the injection port 60a from scattering to the side of the vehicle CA to be cleaned. Further, the foamed liquid agent W2 can be applied on the side surface of the vehicle to be cleaned CA.

  As shown in FIG. 6, the injection nozzle 60 may swing the injection port 60a outward and inward in the vertical direction V at a predetermined swing angle β. At this time, if the outer swing angle β1 in the vertical direction V is smaller than the inner swing angle β2, it is possible to reduce the scattering of the foamy liquid agent W2 to the side of the vehicle CA to be cleaned.

  FIG. 7 shows a piping diagram of the injection nozzle 60. A water pump 69a is provided in the water storage tank 72. The water pump 69a pumps up city water in the water storage tank 72, and a pipe 71a is connected to the drainage side. The pipe 71a is provided with a valve 73c, a high-pressure pump 69b, and an injector 73a in this order from the upstream. The valve 73c adjusts the amount of cleaning water in the pipe 71a, and the high-pressure pump 69b increases the pressure of the cleaning water and sends it out.

  A suction part 71g is immersed in the liquid storage tank 30a, and an injector 73a is connected to a drain side of the suction part 71g via a pipe 71b. A pump 69c and a check valve 73e are provided on the pipe 71b from upstream. The pump 69c pumps up the liquid in the storage tank 30a, and the check valve 73e prevents the liquid from flowing back.

  The liquid agent flowing through the pipe 71b is sucked into the injector 73a by the washing water flowing through the pipe 71a, and the liquid agent diluted to a predetermined concentration flows through the pipe 71i.

  A three-way joint 73b to which the pipe 71c is connected is provided on the pipe 71i. The air pump 70 is connected to the pipe 71c via a check valve 73d. The air pump 70 supplies high-pressure air, and the check valve 73d prevents backflow of air. Thereby, the diluted liquid agent and the high-pressure air are mixed by the three-way joint 73b to form a mixed liquid.

  A foam increasing section 75 is connected downstream of the three-way joint 73b, and an injection nozzle 60 is connected downstream of the foam increasing section 75 via a pipe 71d. After the mixture is increased in the foam increasing section 75, the mixture is injected from the injection nozzle 60 toward the vehicle to be cleaned CA as a foam liquid agent W2 (see FIG. 4).

  FIG. 8 shows a longitudinal sectional view of the foam increasing section 75. The foam increasing section 75 has a cylindrical housing 76, a coil 77 and a collar 78. The housing 76 has an inner peripheral surface formed into a cylindrical surface, and is formed by a flexible hose. The housing 76 may be formed of a hard resin or metal pipe. The upstream end and the downstream end of the housing 76 are connected to a pipe 71i and a pipe 71d via a joint 79, respectively.

  The coil 77 is formed by a tension spring of stainless steel or the like. The coil 77 may be formed by a compression spring. Collars 78 are fitted to both ends of the housing 76.

  The inner diameter dm2 of the collar 78 is formed smaller than the outer diameter dm1 of the coil 77. Therefore, the coil 77 is prevented from coming off by the collar 78.

  When the mixed liquid of the liquid agent and the air enters the foam increasing section 75, it collides with the coil 77, and a large number of fine bubbles are formed to increase the foam. The foamed liquid agent W2 that has been increased in the form of foam has a large specific gravity, so that it is not easily affected by the wind and reaches the vehicle to be cleaned CA without fail. Therefore, the cleaning power of the car washer WA can be improved.

  The collar 78 may be urged by the coil 77. Thereby, since the elastic force for deforming the coil 77 is increased, the deformation of the coil 77 due to the water pressure is suppressed, and the mixture of the liquid agent and the air can be stably increased in a desired foam.

  In the car washer WA having the above configuration, the user drives the vehicle to be washed to stop the vehicle CA in front of the remote panel 7, and sets the washing conditions of the vehicle to be washed CA from within the vehicle to be washed CA. After setting the car wash conditions, the user moves the to-be-cleaned vehicle CA to a position where the car wash can be started by the car wash machine body 1.

  9 to 16 are side views showing a state in which the vehicle CA to be cleaned is washed by the upper surface cleaning device 52. FIG. As shown in FIG. 9, when the vehicle to be washed CA is arranged at the predetermined car wash start position T1, a first outward step in which the high-pressure water W1 is injected from the injection nozzle 59 starts. At the start of the first outward step, the injection unit 53 is arranged at the standby position S1.

  At this time, the ejection nozzle 59 ejects the high-pressure water W1 downward while swinging in the left-right direction integrally with the ejection nozzle 60. Then, as shown in FIG. 10, the arm 55 is extended, and the injection unit 53 moves toward the rear of the vehicle CA in the direction of arrow D1.

  When the injection nozzle 59 moves to the terminal position S2, as shown in FIG. 11, the car wash body 1 moves from the car wash start position T1 toward the rear of the vehicle CA in the direction of arrow D2. At this time, the shape of the vehicle to be cleaned CA is detected by the shape sensor 9.

  Since the detection by the shape sensor 9 is performed after the injection nozzle 59 is disposed at the terminal position S2 distant from the car washer body 1, the adhesion of the high-pressure water W1 to the shape sensor 9 at the time of detection can be reduced. Thereby, erroneous detection by the shape sensor 9 can be prevented.

  As shown in FIG. 12, when the rear end position of the vehicle to be washed CA is detected by the shape sensor 9, the car wash machine main body 1 stops and is arranged at the car wash end position T2.

  The car wash body 1 is inverted at the car wash end position T2, and moves toward the front of the vehicle CA to be washed in the direction of arrow D3 as shown in FIG. 13 to perform the first return path process. In the first return path step, the foaming liquid W2 is sprayed from the spraying nozzle 60 while the spraying nozzle 60 swings in the left-right direction.

  As shown in FIG. 14, the car wash machine main body 1 stops after moving from the car wash end position T2 to the car wash start position T1. During this time, the injection nozzle 60 injects the foamy liquid agent W2 while being disposed at the terminal position S2 remote from the car washer body 1, and the foamy agent W2 is gradually applied to the vehicle CA to be washed from behind. You. For this reason, the progress of the application of the foamy liquid agent W2 can be easily visually recognized from the surroundings without being blocked by the car wash machine main body 1, and the effect of foam washing can be exhibited.

  Then, when the car wash machine body 1 stops at the car wash start position T1, the injection nozzle 60 moves from the terminal position S2 to the standby position S1 in the direction of arrow D4 while continuing the injection of the foamy liquid agent W2. Thereby, the upper surface and the side surface of the vehicle to be cleaned CA are covered with the foamy liquid agent W2.

  At this time, since the plurality of injection ports 60a of the injection nozzle 60 are arranged at the same position in the front-rear direction, they swing in the same swing plane. For this reason, the foam liquid W2 injected from each injection opening 60a overlaps, and the thickness of the foam liquid W2 on the vehicle CA to be cleaned can be increased. This prevents the foamy liquid agent W2 attached to the vehicle to be cleaned CA from scattering due to the wind, and allows the foamy liquid agent W2 to reliably remain.

  Further, since the thick liquid foam W2 spreads in the front-rear direction, the liquid foam W2 can be applied to the vehicle CA to be cleaned without gaps even if the swing cycle of the injection nozzle 60 is lengthened. For this reason, the failure of the swing mechanism of the injection nozzle 60 can be reduced.

  As shown in FIG. 15, when the injection nozzle 60 moves to the standby position S1, the first return path process ends. In addition, in the first outward path process and the first backward path step, each rotating brush maintains a stopped state.

  When the first return path process is completed, as shown in FIG. 16, the car wash machine main body 1 is turned over and moved toward the rear of the vehicle to be cleaned CA in the direction of arrow D5 to perform the second forward path process. In the second outward path step, the injection from the injection unit 53 is stopped, and each rotating brush is driven to clean the vehicle CA to be cleaned.

  When the second outward pass process is completed, the car wash machine body 1 is turned over and moves toward the front of the vehicle to be washed CA, and the second return pass process is performed. At this time, in the second return path step, the high pressure water W1 is injected from the injection nozzle 59 and the water purification nozzles 11 and 13, and the rotating brush is driven. Thereby, the foamy liquid agent W2 remaining on the vehicle to be cleaned CA can be washed away.

  Further, in the second return path process, the injection unit 53 may be moved in a reverse direction with respect to the car washer body 1 at a predetermined position of the vehicle to be cleaned CA, and the relative speed of the injection nozzle 59 with respect to the vehicle to be cleaned CA may be reduced. For example, the spray nozzle 59 moves in the direction from the standby position S1 to the end position S2, and performs cleaning by reducing the relative speed of the spray nozzle 59 at the upper end of the rear window or the wiper portion on the front window. As a result, it is possible to reliably wash away the foamy liquid agent that tends to remain on the wiper portion on the front window of the vehicle to be cleaned CA, the spoiler portion on the upper end of the rear window, and the like.

  When the second return path step is completed, the car wash machine main body 1 is turned over and moves toward the rear of the vehicle CA to be cleaned, and the third forward path step is performed. In the third outward step, drying of the vehicle to be cleaned CA is performed by sending air from the blowing nozzle. At this time, the injection nozzle 59 is disposed at the end position S2, and injects the high-pressure water W1 from the injection nozzle 59.

  Accordingly, the foamy liquid agent remaining in the vehicle to be cleaned CA can be more reliably washed away. Further, since the injection nozzle 59 and the blowing nozzle are largely separated in the front-rear direction, it is possible to prevent water from scattering on the dried area of the vehicle CA to be cleaned. Note that water at a lower pressure than in the second return step may be injected from the injection nozzle 59 in the third outward step. This makes it possible to more reliably prevent water from scattering on the dried area.

  The second returning step and the third outward step may be omitted, and the drying may be performed by blowing air from the blowing nozzle in the second outward step. At this time, the relative speed of the injection nozzle 59 may be reduced at a predetermined position as described above.

  According to the present embodiment, the injection nozzle 60 (first injection nozzle) is provided so as to swing in the left-right direction. Accordingly, even when the injection speed of the foam liquid W2 injected from the injection nozzle 60 is increased, the foam liquid W2 can be injected toward a wide range in the left-right direction of the vehicle CA to be cleaned. Thereby, the foamed liquid W2 is hardly affected by the wind, and the foamed liquid W2 can reliably reach the vehicle to be cleaned CA. Therefore, the cleaning power of the car washer WA can be improved.

  Further, injection nozzles 60 are provided at both left and right end portions, respectively. Thereby, foamy liquid agent W2 can be easily applied on the side surface of vehicle CA to be cleaned.

  Further, the injection nozzle 60 swings within a predetermined range in which the injection port 60a faces inward with respect to the vertical. For this reason, it is possible to prevent the foamed liquid agent W2 injected from the injection port 60a from scattering to the side of the vehicle CA to be cleaned. Further, the foamed liquid agent W2 can be applied on the side surface of the vehicle to be cleaned CA.

  Further, the injection nozzle 60 swings within a predetermined range in which the injection port 60a is directed outward and inward with respect to the vertical, and the swing angle in which the injection port 60a is directed outward with respect to the vertical is inward. It may be smaller than the moving angle. Thereby, it is possible to prevent the foamed liquid agent W2 injected from the injection port 60a from scattering to the side of the vehicle CA to be cleaned.

  Further, the injection nozzle 60 has a plurality of injection ports 60a arranged side by side in the left-right direction. For this reason, the foam liquid W2 injected from each injection opening 60a overlaps, and the thickness of the foam liquid W2 on the vehicle CA to be cleaned can be increased. This prevents the foamy liquid agent W2 attached to the vehicle to be cleaned CA from scattering due to the wind, and allows the foamy liquid agent W2 to reliably remain.

  In addition, an ejection nozzle 59 is provided between the left and right ejection nozzles 60 and swings integrally with the ejection nozzle 60 to eject the high-pressure water W1. Thereby, the foamy liquid agent W2 can be easily washed away by the high-pressure water W1.

  Further, the swing motor 62, a support 64 (first support) holding the ejection nozzle 60, a support 65 (second support) holding the ejection nozzle 59, the swing motor 62 and the support 65. And a link member 67a, 67b connecting the support portion 65 and the support portion 64 to each other. Thus, the injection nozzle 60 and the injection nozzle 59 that swing together can be easily realized.

  Further, an ejection nozzle 60 (first ejection nozzle) is provided so as to be swingable in the left-right direction, and the ejection nozzle 60 swings in the left-right direction to eject the foam liquid W2. Accordingly, even when the injection speed of the foam liquid W2 injected from the injection nozzle 60 is increased, the foam liquid W2 can be injected toward a wide range in the left-right direction of the vehicle CA to be cleaned. Thereby, the foamed liquid W2 is hardly affected by the wind, and the foamed liquid W2 can reliably reach the vehicle to be cleaned CA. Therefore, the cleaning power of the car washing method can be improved.

  In the present embodiment, the injection nozzle 59 and the injection nozzle 60 are arranged so as to protrude from the entrance surface 1a of the car wash machine main body 1, but may be arranged inside the car wash machine main body 1. At this time, the injection nozzle 59 and the injection nozzle 60 move relative to the vehicle to be washed by the movement of the car wash machine body 1. Further, the cleaning by the rotating brush may be omitted, and the vehicle to be cleaned CA may be cleaned only by the injection nozzle 59 and the injection nozzle 60.
