  In addition, a first forward process for injecting high-pressure water W1 from the injection nozzle 32 with the rotary brush stopped, a return path process for injecting the foamy foam liquid W2 from the injection nozzle 32 with the rotary brush stopped, and the injection nozzle And a second forward path step of stopping the injection of 32 and driving the rotary brush. Thereby, the car wash machine WA that can improve the cleaning power can be easily realized.

  In addition, after the injection nozzle 32 moves on the guide portion 40 toward the rear of the vehicle to be cleaned CA and is disposed at the terminal position S2 in the first forward path process, the car wash machine body 1 moves from the car wash start position T1 to the vehicle to be cleaned. Move toward the back of the CA. Further, after the car wash machine main body 1 moves toward the front of the vehicle to be cleaned CA and is disposed at the car wash start position T1 in the return path process, the injection nozzle 32 moves on the guide portion 40 toward the front of the vehicle to be cleaned CA. Moving. Thereby, the injection nozzle 32 is arranged at the terminal position S2 away from the car wash machine main body 1, and the car wash machine main body 1 moves. Therefore, the adhesion of the cleaning liquid onto the entrance surface 1a of the car wash machine main body 1 can be reduced, and the operation panel 8 and the like disposed on the entrance surface 1a can be kept clean.

  Further, a shape sensor 9 for detecting the shape of the vehicle to be cleaned CA is provided in the vicinity of the entrance surface 1a of the car wash machine main body 1, and the car wash machine main body 1 moves with the injection nozzle 32 disposed at the terminal position S2.

This makes it difficult for snow to accumulate on the cover 57, and the arm 55 can be smoothly moved even during snowfall.

  Further, the car wash machine main body 1 is provided with an air temperature sensor (not shown) for detecting the outside air temperature. When the outside air temperature is lower than a predetermined temperature, the arm 55 moves faster in the front-rear direction after the car wash condition is received by the remote panel 7 and before the start of car wash. Thereby, the snow on the cover 57 can be shaken off and the arm 55 can be moved smoothly.

  FIG. 11 shows a front view of the injection unit 53. A swing motor 62, an injection nozzle 59, and an injection nozzle 60 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. The injection nozzle 59 is connected to the distribution pipe section 31, and high-pressure water W1 (see FIG. 15) 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.

  FIG. 13 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. 11).

  FIG. 14 is a longitudinal 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. At this time, when the outside air temperature is lower than the predetermined temperature, the arm 55 is accelerated more rapidly than the movement at the time of car washing, which will be described later, and moves in the front-rear direction before the car wash starts. Thereby, the snow on the cover 57 and the arm 55 can be shaken off and the arm 55 can be moved smoothly. 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.

  15 to 22 are side views showing a state in which the vehicle to be cleaned CA is washed by the upper surface cleaning device 52. As shown in FIG. 15, 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. 16, 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 terminal position S2, as shown in FIG. 17, the car wash machine body 1 moves from the car wash start position T1 in the direction of arrow D2 toward the rear of the vehicle to be cleaned CA. 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. 18, 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 T <b> 2.

  The car wash machine body 1 reverses 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. 19 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. 20, 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. 21, when the injection nozzle 60 moves to the standby position S1, the first return path step 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. 22, the car wash machine body 1 is reversed and moved in the direction of arrow D5 toward the rear of the vehicle to be cleaned CA, and the second forward path process is performed. 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 rotating brush arranged in the car wash machine body 1, the guide part 54 arranged in the car wash machine body 1, and the front and rear direction projecting from the entrance surface 1 a of the car wash machine body 1 by the guide part 54. And spray nozzles 59 and 60 for spraying the cleaning liquid. For this reason, after performing preliminary cleaning with the injection nozzles 59 and 60, cleaning with a rotating brush can be performed to improve the cleaning power. Further, it is not necessary to arrange the frame straddling the vehicle to be cleaned CA in the front-rear direction of the car wash machine body 1, and the car wash machine WA can be downsized.

  In addition, an arm 55 that extends in the front-rear direction and whose projection amount with respect to the inlet surface 1 a is variable by guidance of the guide portion 54 is provided, and an injection nozzle 59 and an injection nozzle 60 are provided at the tip of the arm 55. Thereby, the injection nozzle 59 and the injection nozzle 60 can be easily guided in the front-rear direction.

  In addition, an air temperature sensor that detects the outside air temperature is provided, and when the outside air temperature is lower than a predetermined temperature, the arm 55 moves in the front-rear direction before the start of the car wash. Thereby, the snow on the cover 57 and the arm 55 is shaken off, and the arm 55 can be moved smoothly.

  Moreover, the high pressure water W1 is injected from the injection nozzle 59, and the foamy liquid liquid W2 is injected from the injection nozzle 60. Thereby, the foamed liquid agent W2 applied on the vehicle to be cleaned CA is washed away by the high-pressure water W1, and the vehicle CA to be cleaned can be reliably cleaned.

  Moreover, the injection nozzle 60 that injects the foam-like foam liquid W2 has a plurality of injection ports 60a that swing within the same swinging surface. Thereby, the foamy liquid agent W2 injected from each injection port 60a overlaps, and the thickness of the foamed liquid agent W2 on the to-be-cleaned vehicle CA can be increased. For this reason, 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. Therefore, the detergency with the foamed liquid W2 can be improved.

  Moreover, the injection nozzle 60 which injects the foam-like foam liquid W2 to the both outer sides of the left-right direction with respect to the injection nozzle 59 which injects the high pressure water W1 is arranged. Thus, the foam liquid W2 can be easily applied on the side surface of the vehicle CA to be cleaned. Moreover, since the high-pressure water W1 sprayed on the upper surface of the vehicle to be cleaned CA flows down on the side surface of the vehicle to be cleaned CA, the foam liquid W2 can be washed away.

  In addition, a second return path step in which the car wash machine body 1 moves toward the front of the vehicle to be cleaned CA and injects the high-pressure water W1 from the injection nozzle 59, and the car wash machine body 1 moves toward the rear of the vehicle to be cleaned CA. And a third forward step of drying the vehicle CA to be cleaned by the drying unit. Thereby, the foamy liquid W2 that tends to remain can be reliably washed away by the second return path step.

  In addition, a shape sensor 9 for detecting the shape of the vehicle to be cleaned CA is provided in the vicinity of the entrance surface 1a, and in the second return path process, injection is performed in a direction opposite to the moving direction of the car wash machine body 1 at a predetermined position of the vehicle to be cleaned CA. The nozzle 59 was moved. As a result, cleaning is performed at a lower relative speed of the spray nozzle 59 at the upper end of the rear window or the wiper portion on the front window. For this reason, it is possible to reliably wash away the foamy liquid W2 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.

  Further, in the third forward path step, the high-pressure water W1 was sprayed from the spray nozzle 59 disposed at the terminal position S2. Thereby, scattering of the high-pressure water W1 to the dried region can be prevented, and the foamed liquid agent W2 can be washed away more reliably.

  In the present embodiment, the cleaning of the vehicle CA to be cleaned may be performed using only the injection nozzle 59 and the injection nozzle 60 without performing the cleaning by the rotating part brush.

  Alternatively, the injection nozzle 59 and the injection nozzle 60 may be connected in parallel downstream of the foam increasing portion 75 to switch between a state where the air pump 70 and the pump 69c are driven and a state where the air pump 70 and the pump 69c are stopped. Thereby, the foam liquid W2 and the high-pressure water W1 can be switched and ejected from the ejection nozzle 59 and the ejection nozzle 60.

  In the first embodiment, a second return path process and a third outbound path process similar to those in the present embodiment may be provided. Thereby, the foamy liquid agent which remains easily can be washed away reliably.

  Further, in the first embodiment, when the outside air temperature is lower than a predetermined temperature, the arm 55 may be accelerated more rapidly than the movement at the time of car washing before the car washing starts and may move in the front-rear direction.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine provided with the injection nozzle which protrudes from the entrance surface of a car wash machine main body, and moves back and forth.
