The wax nozzle 16 is disposed on the exit surface 1b side of the car wash machine body 1 and injects liquid wax onto the vehicle CA to be cleaned.

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

  FIG. 3 shows a schematic top view of the car wash machine body 1. The upper surface cleaning device 52 has a guide part 54, an arm 55, and an injection part 53. A pair of left and right guide portions 54 are provided on the ceiling surface 1c of the car wash machine body 1 so as to extend in the front-rear direction. The guide portion 54 has a U-shaped longitudinal cross-sectional shape, and an opening (not shown) extending in the front-rear direction opens on the opposing inner surface.

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

  A guide motor 63 having a sprocket (not shown) on the motor shaft 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 at the other end. Arranged. A 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-rear direction. Thereby, the injection part 53 provided at the tip of the arm 55 extends from the car wash machine main body 1 toward the rear of the vehicle CA to be cleaned from the standby position S1 (see FIG. 9) close to the car wash machine main body 1. It moves between the terminal position S2 (see FIG. 10).

  The injection unit 53 is covered with a cover 57 attached to a tip 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 accumulate on the cover 57, and the arm 55 can be smoothly moved even during snowfall.

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

  The swing motor 62 is attached to the central portion 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 the shaft portion 62 a of the swing motor 62. The crank 66 has a rotating plate 66a attached to the shaft portion 62a and an arm 66b rotatably supported on a peripheral portion of the rotating plate 66a.

  A pair of right and left spray nozzles 59 are provided at the center of the base 58 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 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 about the shaft portion 65a. One end of an arm 66b of the crank 66 is rotatably connected to the upper end of one support portion 65.

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

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

  When the swing motor 62 is driven, the support portion 64 and the support portion 65 swing in the left-right direction via the crank 66 and the link members 67a and 67b. Along with this, the injection nozzle 60 and the injection nozzle 59 swing together. At this time, since the injection port 60a of the injection nozzle 60 and the injection port 59a of the injection nozzle 59 are arranged at the same position with respect to the front-rear 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 spray nozzle 60 swings at a predetermined swing angle α within a range in which the spray port 60 a faces inward with respect to the vertical direction V. For this reason, scattering of the foamed liquid agent W2 ejected from the ejection port 60a to the side of the vehicle CA to be cleaned can be prevented. Moreover, the foamed liquid agent W2 can be applied on the side surface of the vehicle CA to be cleaned.

  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 rocking angle β1 in the vertical direction V is made smaller than the inner rocking angle β2, scattering of the foam liquid W2 to the side of the vehicle CA to be cleaned can be reduced.

  FIG. 7 shows a piping diagram of the injection nozzle 60. A water pump 69 a is disposed in the water storage tank 72. The water pump 69a pumps city water in the water storage tank 72, and a pipe 71a is connected to the drain side. The pipe 71a is provided with a valve 73c, a high-pressure pump 69b, and an injector 73a in 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 the 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 agent in the liquid storage tank 30a, and the check valve 73e prevents the liquid agent from flowing back.

  The liquid agent flowing through the pipe 71b is sucked into the injector 73a by the cleaning 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. An 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 high pressure air are mixed by the three-way joint 73b, and a liquid mixture is formed.

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

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

  The coil 77 is formed by a tension spring such as stainless steel. The coil 77 may be formed by a compression spring. A collar 78 is 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. For this reason, the coil 77 is prevented from coming off by the collar 78.

  When the liquid mixture of the liquid agent and air enters into the foam increasing portion 75, it collides with the coil 77 to form a large number of fine bubbles and increase in foam. The foamed liquid agent W2 increased in the form of foam has a large specific gravity, and thus is less likely to be affected by the wind and reliably reaches the vehicle CA to be cleaned, and hardly drops on the side surface of the vehicle CA to be cleaned. Therefore, the cleaning power of the car wash machine WA can be improved.

  The collar 78 may be urged by the coil 77. Thereby, since the elastic force which deform | transforms the coil 77 becomes large, the deformation | transformation of the coil 77 by water pressure can be suppressed, and the liquid mixture of a liquid agent and air can be stably bubble-expanded to desired foam form.

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

  9-16 is a side view which shows the state which wash | cleans the to-be-cleaned vehicle CA by the upper surface washing | cleaning apparatus 52. FIG. As shown in FIG. 9, when the vehicle to be cleaned CA is arranged at a predetermined car wash start position T1, the first forward path process in which the high-pressure water W1 is jetted from the jet nozzle 59 is started. At the start of the first forward process, the injection unit 53 is disposed at the standby position S1.

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

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

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

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

  The car wash machine body 1 is reversed at the car wash end position T2, and moves toward the front of the vehicle to be cleaned CA in the direction of the arrow D3 as shown in FIG. 13 to perform the first return pass process. In the first return path process, the foaming liquid W2 is ejected from the ejection nozzle 60 while the ejection 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 foam liquid W2 while being disposed at the terminal position S2 away from the car wash machine body 1, and the foamed liquid W2 is gradually applied from the rear onto the vehicle CA to be cleaned. The For this reason, the progress of the application of the foam liquid W2 can be easily seen from the surroundings without being obstructed by the car wash machine body 1, and the effect of foam cleaning can be exhibited.

  When the car wash machine main body 1 stops at the car wash start position T1, the injection nozzle 60 moves from the end position S2 to the standby position S1 in the direction of the arrow D4 while continuing to inject the foamy foam liquid W2. Thereby, the upper surface and side surface of the to-be-cleaned vehicle CA are covered with the foamy foam liquid 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, the injection nozzle 60 swings within the same swinging surface. For this reason, the foam liquid W2 injected from each injection port 60a overlaps, and the thickness of the foam liquid W2 on the to-be-cleaned vehicle CA can be increased. As a result, it is possible to prevent the foamed liquid agent W2 adhering to the vehicle to be cleaned CA from being scattered by the wind, and to reliably leave the foamed liquid agent W2.

  Further, since the thick foam liquid W2 spreads in the front-rear direction, the foam liquid W2 can be applied onto the vehicle CA to be cleaned without a gap even if the oscillation period of the injection nozzle 60 is increased. For this reason, failure of the swinging 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 is completed. In the first forward path process and the first return path process, each rotary brush maintains a stopped state.

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

  When the second forward path process is completed, the car wash machine body 1 is reversed and moved toward the front of the vehicle to be cleaned CA, and the second return path process is performed. At this time, the high pressure water W1 is jetted from the jet nozzle 59 and the water purification nozzles 11 and 13 in the second return path process, and the rotating brush is driven. Thereby, the foamed liquid agent W2 remaining on the to-be-cleaned vehicle CA can be washed out.

  Further, in the second return path process, the injection unit 53 may be moved in a reverse direction with respect to the car wash machine main 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 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. Thereby, it is possible to surely wash away the foamy liquid agent that tends to remain on the wiper portion on the front window of the vehicle CA to be cleaned, the spoiler portion on the upper end of the rear window, and the like.

  When the second return path process is completed, the car wash machine body 1 is reversed and moved toward the rear of the vehicle CA to be cleaned, and the third forward path process is performed. In the third forward path process, air is sent from the blow nozzle to dry the vehicle CA to be cleaned. At this time, the injection nozzle 59 is arranged at the terminal position S2, and the high-pressure water W1 is injected from the injection nozzle 59.

  Thereby, the foamed liquid agent remaining in the vehicle to be cleaned CA can be more reliably washed away. In addition, since the spray nozzle 59 and the air blowing nozzle are greatly separated in the front-rear direction, it is possible to prevent water from being scattered on the dried area of the vehicle CA to be cleaned. Note that water having a lower pressure than in the second return path step may be injected from the injection nozzle 59 in the third outward path step. Thereby, scattering of water on the dried region can be more reliably prevented.

  Note that the second return path process and the third outbound path process may be omitted, and drying may be performed by blowing air from the blow nozzle in the second outbound path process. At this time, the relative speed of the injection nozzle 59 may be decreased at a predetermined position as described above.

  According to the present embodiment, the injection nozzle 60 (first injection nozzle) is provided so as to be swingable in the left-right direction. Thereby, even if it increases the injection speed of the foaming liquid agent W2 injected from the injection nozzle 60, the foaming liquid agent W2 can be injected toward the wide range of the left-right direction of the to-be-cleaned vehicle CA. Thereby, the foamed liquid agent W2 is hardly affected by the wind, and the foamed liquid agent W2 can reliably reach the vehicle CA to be cleaned. Therefore, the cleaning power of the car wash machine WA can be improved.

  In addition, jet nozzles 60 are provided at the left and right ends, respectively. Thereby, the foamed liquid agent W2 can be easily applied on the side surface of the vehicle CA to be cleaned.

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

  Further, the spray nozzle 60 swings within a predetermined range in which the spray port 60a faces outward and inward with respect to the vertical, and the swing angle with the spray port 60a facing outward with respect to the vertical swings inward. It may be smaller than the moving angle. Thereby, scattering of the foamed liquid agent W2 ejected from the ejection port 60a to the side of the vehicle CA to be cleaned can be prevented.

  Moreover, 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 port 60a overlaps, and the thickness of the foam liquid W2 on the to-be-cleaned vehicle CA can be increased. As a result, it is possible to prevent the foamed liquid agent W2 adhering to the vehicle to be cleaned CA from being scattered by the wind, and to reliably leave the foamed liquid agent W2.

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

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

  Further, the injection nozzle 60 (first injection nozzle) is provided so as to be swingable in the left-right direction, and the injection nozzle 60 swings in the left-right direction to spray the foam liquid W2. Thereby, even if it increases the injection speed of the foaming liquid agent W2 injected from the injection nozzle 60, the foaming liquid agent W2 can be injected toward the wide range of the left-right direction of the to-be-cleaned vehicle CA. Thereby, the foamed liquid agent W2 is hardly affected by the wind, and the foamed liquid agent W2 can reliably reach the vehicle CA to be cleaned. Therefore, the cleaning power of the car wash method can be improved.
