  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 the side blowing nozzle 22 and the top blowing nozzle 41. The side blowing nozzles 22 are respectively provided on both side portions of the car wash machine body 1 and blow air toward the side surface of the vehicle CA to be cleaned.

  The top blowing nozzle 41 is reciprocated in the left-right direction by a moving mechanism 35 disposed on the ceiling 91 and blows air toward the upper surface of the vehicle CA to be cleaned. The to-be-cleaned vehicle CA can be dried by blowing air from the side blowing nozzle 22 and the top blowing nozzle 41.

  A plurality of moving mechanisms 35 are juxtaposed in the left-right direction at the lower part of the ceiling portion 91 and each have a top blowing nozzle 41 that is a movable body that reciprocates. 3 and 4 show a front view and a side sectional view of the moving mechanism 35. The moving mechanism 35 is provided on a mounting plate 91 a arranged vertically on the ceiling portion 91. A housing 47 is attached to the mounting plate 91a so as to have a U-shaped cross-section with the back side open and cover the moving mechanism 35.

  A pair of sprockets 48 and 49 that are rotatably attached to the attachment plate 91a are arranged on the left and right ends in the housing 47. One sprocket 48 is rotationally driven by a motor (not shown). A chain 50 forming an endless track is wound around the sprockets 48 and 49. A support member 42 is attached to the chain 50.

  5 to 7 are a front view, a top view, and a side view showing a mounting state of the support member 42. In the chain 50, pins 50c are inserted into the alternately arranged outer links 50a and inner links 50b, and the adjacent inner links 50b are connected by the outer links 50a. The support member 42 extends in the axial direction a pin 50c inserted through one outer link 50a, and the support member 42 having a pentagonal front shape is attached to the outer link 50a via the pin 50c. A boss 42b having a circular cross section is provided below the support member 42.

  3 and 4, the boss 42 b is fitted with a mounting portion 46 provided integrally with the top blowing nozzle 41 to rotatably support the mounting portion 46, and forms a rotating shaft 42 a of the top blowing nozzle 41. At this time, the distance d between the pitch line of the chain 50 and the rotating shaft 42a is formed to coincide with the radius R of the pitch circle of the sprockets 48 and 49. The mounting portion 46 is inserted into an opening 47 a provided on the lower surface of the housing 47 so as to extend in the left-right direction, and the top blower nozzle 41 is disposed below the housing 47.

  A guide member 45 extending in parallel with a center line C connecting the rotation centers of both sprockets 48 and 49 is attached to the inner surface 47 b of the front wall of the housing 47. A fitting member 46 a provided with a recess 46 b that fits into the guide member 45 is attached to the front surface of the attachment portion 46. By sliding between the guide member 45 and the fitting member 46a, the top blowing nozzle 41 integral with the mounting portion 46 is guided in the left-right direction parallel to the center line C.

  When the sprocket 48 is rotated by driving the motor, the chain 50 rotates in one direction. Thereby, the top blowing nozzle 41 integral with the support member 42 is moved to the left, for example, by the guide of the guide member 45. Since the distance d between the pitch line of the chain 50 and the rotation shaft 42a matches the radius R of the pitch circle of the sprockets 48, 49, the rotation shaft 42a is arranged on the rotation center of the left sprocket 48 by the movement of the support member 42. Is done.

  When the chain 50 further circulates, the position of the top blowing nozzle 41 is maintained and the support member 42 rotates 180 ° on the sprocket 48, and then the support member 42 and the top blowing nozzle 41 move to the right. Similarly, the support member 42 rotates 180 ° on the right sprocket 49. Accordingly, the top blowing nozzle 41 reciprocates by one-way circulation of the chain 50. At this time, the reciprocating range of the top blowing nozzle 41 coincides with the distance L between the rotation centers of the sprockets 48 and 49, and the moving mechanism 35 can be downsized.

  The top blower nozzle 41 is suspended by its own weight with respect to the support member 42 with the rotation shaft 42a disposed horizontally. For this reason, even if the guide member 45 is omitted, the top blowing nozzle 41 can be reciprocated by the moving mechanism 35. However, it is more desirable to provide the guide member 45 because the top blow nozzle 41 that is a movable body can be prevented from swinging.

  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 7A, 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 to-be-washed vehicle CA to a predetermined washing start position. Then, the car wash machine main body 1 moves in the front-rear direction, straddles the vehicle to be cleaned CA, and cleaning with the top brush 4 and the side brush 5 is performed.

  Thereafter, air is blown from the side blowing nozzle 22 and the top blowing nozzle 41 toward the vehicle CA to be cleaned to dry the vehicle CA to be cleaned. At this time, each top blowing nozzle 41 independently reciprocates in the left-right direction to blow air.

  According to the present embodiment, the distance d between the pitch line of the chain 50 and the rotation shaft 42a of the top blowing nozzle 41 (movable body) coincides with the radius R of the pitch circle of the sprockets 48, 49, so As a result, the top blowing nozzle 41 reciprocates. Thereby, since the conventional limit switch is unnecessary, the cost of the car wash machine 1 can be reduced.

  Moreover, since the reciprocating range of the top blowing nozzle 41 is the distance L between the rotation centers of the sprockets 48 and 49, the moving mechanism 35 can be downsized to reduce the size of the car wash machine 1. In addition, since it is not necessary to repeatedly reverse the motor that drives the sprocket 48, the occurrence of motor failure can be reduced.

  Further, since the guide member 45 for guiding the top blowing nozzle 41 in a direction parallel to the center line L1 connecting the rotation centers of the sprockets 48 and 49 is provided, the top blowing nozzle 41 can be prevented from swinging. In addition, you may arrange | position the rotating shaft 42a of the top ventilation nozzle 41 which is a movable body, and the rotating shaft of the sprockets 48 and 49 vertically. At this time, the guide member 45 can prevent the top blowing nozzle 41 and the support member 42 from rotating together on the sprockets 48 and 49. Therefore, the top blowing nozzle 41 can be reliably reciprocated.

  Moreover, since the rotating shaft 42a is horizontally arranged and the top blowing nozzle 41 is suspended from the support member 42 by its own weight, the moving mechanism 35 for reciprocating the top blowing nozzle 41 can be easily realized.

  In addition, the chain 50 is formed by connecting the adjacent inner links 50b by the outer links 50a, and the support member 42 is attached to the one outer link 50a, so that the top blow nozzle 41 can be rotated by rotating the chain 50 integrally. The supporting member 42 to support can be formed easily.

  Further, since the movable body is composed of the top blowing nozzle 41 that sends out air to dry the vehicle CA to be cleaned, the moving mechanism 35 can be easily realized.

  In addition, since a plurality of moving mechanisms 35 are arranged in the left-right direction on the ceiling portion 91 of the car wash machine main body 1 and the top blow nozzles 41 respectively provided in the moving mechanisms 35 independently reciprocate in the left-right direction, The ceiling surface can be easily dried.

  In the present embodiment, the movable body that reciprocates in the left-right direction by the moving mechanism 35 is composed of the top blowing nozzle 41, but other movable bodies may be reciprocated. For example, the side blowing nozzle 22 may be reciprocated in the vertical direction by the same moving mechanism 35. A rotating brush such as the side blowing nozzle 22 or the rocker brush 6 may be reciprocated in the vertical direction by the same moving mechanism 35. Further, the liquid jet nozzles such as the first and second water purification nozzles 11 and 13, the first and second detergent nozzles 12 and 15, the water repellent coating nozzle 14, and the wax nozzle 16 are reciprocated in the left-right direction by the same moving mechanism 35. It may be moved.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine provided with the moving mechanism which moves movable bodies, such as a ventilation nozzle, reciprocatingly.
