JP-A-6-72294 JP2004-136893

  The car wash machine described in Patent Document 1 performs drying in the final return path of the portal frame by the front drying device, and the upper surface drying nozzle of the front drying device dries the upper surface from the rear end to the front end of the vehicle. Yes. At this time, the upper surface drying nozzle of the front-side drying device causes the water droplets on the upper surface of the vehicle to be the highest (at the height level) located in the middle of the vehicle front-rear direction from the lower (lower height level) upper surface side of the rear end side. High) The top surface of the vehicle is dried while blowing up toward the top surface (roof top surface), the efficiency of the drying operation is poor, and the blowing power of the top surface drying nozzle is increased.

  The car wash machine described in Patent Document 2 performs drying in the final forward path of the portal frame by a rear drying device, and dries the upper surface from the front end to the rear end of the vehicle by the upper surface drying nozzle of the rear drying device. It is going to be. At this time, the upper surface drying nozzle of the rear-side drying device causes the water droplets on the upper surface of the vehicle to be the highest (at the height level) located in the middle of the front and rear direction of the vehicle from the lower upper surface side (lower height level). High) The top surface of the vehicle is dried while blowing up toward the top surface (roof top surface), the efficiency of the drying operation is poor, and the blowing power of the top surface drying nozzle is increased.

  An object of the present invention is to improve drying work efficiency when the upper surface of a vehicle is dried by a drying device of a car wash machine.

  According to a first aspect of the present invention, there is provided a car washing method using a car wash machine that includes a frame that relatively moves in the front-rear direction of the vehicle, and that dries the vehicle after being washed by a drying device provided on the frame. A drying nozzle is provided, and the upper surface drying nozzle starts drying from the highest upper surface in the longitudinal direction of the vehicle toward the rear end and the front end of the vehicle.

  According to a second aspect of the present invention, in the first aspect of the invention, further, a drying device is provided before and after the frame, and the upper surface drying nozzle of the front side drying device dries from the highest upper surface in the vehicle front-rear direction to the rear end of the vehicle. Then, the process of drying from the highest upper surface in the front-rear direction of the vehicle to the front end of the vehicle is performed in order by the upper surface drying nozzle of the rear-side drying device.

(Claim 1)
(a) The upper surface drying nozzle of the drying apparatus starts drying from the highest upper surface in the longitudinal direction of the vehicle toward the rear end and the front end of the vehicle, thereby causing water droplets on the upper surface of the vehicle to be lower from the highest upper surface side. The upper surface of the vehicle is dried while blowing down toward the side of the vehicle, so that the drying work efficiency can be improved and the blowing power of the upper surface drying nozzle can be reduced.

(Claim 2)
(b) When the drying process is finished on the rear end side of the vehicle, the upper surface drying nozzle of the rear side drying device causes the upper surface on the front half side of the vehicle (the upper surface from the highest upper surface located in the middle of the vehicle longitudinal direction to the front end of the vehicle). ) Is finished, the upper surface drying nozzle of the front drying device located near the middle in the front-rear direction of the vehicle causes the rear upper surface of the vehicle (from the highest upper surface located in the middle of the vehicle front-rear to the rear of the vehicle). Drying of the top surface to the end can be started immediately, and the car wash time can be shortened.

  (c) When finishing the drying process on the front end side of the vehicle, the upper surface drying nozzle of the front drying device causes the rear upper surface of the vehicle (upper surface from the highest upper surface located in the middle in the vehicle front-rear direction to the rear end of the vehicle). When drying of the vehicle is completed, the upper surface drying nozzle of the rear drying device located near the middle in the front-rear direction of the vehicle causes the upper surface of the front half of the vehicle (from the highest upper surface located in the middle of the vehicle front-rear direction to the front end of the vehicle). (Upper surface) can be started immediately and the car wash time can be shortened.

The air blowers 37A and 37B stop the air blowing, and the drying of the side surface and the upper surface of the first half side of the vehicle 1 by the drying device 30 is finished. The upper surface drying nozzle 32 of the drying device 30 is returned to the rising end.

(8) Car wash completed (Figure 10 (E))
While returning the upper surface drying nozzle 32 of the drying device 30 to the rising end and returning the portal frame 11 to the original position on the rail 12, the car wash is finished.

  According to the present embodiment, the upper surface drying nozzle 32 of the drying device 30 starts drying from the highest upper surface in the front-rear direction of the vehicle toward the rear end and the front end of the vehicle. The upper surface of the vehicle is dried while blowing down from the upper surface side toward the lower upper surface side, so that the drying work efficiency can be improved and the blowing power of the upper surface drying nozzle 32 can be reduced.
