  A ventilation pipe 36 extending in the left-right direction is attached to a lower portion of the top blowing nozzle 21 on an attachment surface 21 b facing the outlet surface 1 b of the car wash machine body 1. A plurality (six in this embodiment) of amplification nozzles 35 (second blowing nozzles) are connected to the ventilation pipe 36. The ventilation pipe 36 is connected to an air tank 38 by a hose 37 disposed in the right duct 32. A solenoid valve (not shown) is disposed at the connection between the hose 37 and the air tank 38. Thereby, the air supply path with respect to the top ventilation nozzle 21 and the amplification nozzle 35 is provided independently.

  Since the air tank 38 (see FIG. 2) stores compressed air having a pressure higher than that of the blower 20, the amplification nozzle 35 can send air having a pressure higher than that of the top blowing nozzle 21. Moreover, since the hose 37 is supported by the inner wall in the duct 32, the hose 37 can be prevented from being damaged by the sliding of the car wash machine body 1 and the hose 37 when the top blowing nozzle 21 is moved up and down.

  4 and 5 show a front view and a top view of the amplification nozzle 35. The amplifying nozzle 35 is formed in a T shape when viewed from above, and a rear end connection port 35 f is connected to the ventilation pipe 36. A front surface 35e of the amplification nozzle 35 is formed extending in the left-right direction, and a plurality of exhaust holes 35b communicating with the connection port 35f are arranged in parallel in the left-right direction in two rows. A plurality of intake holes 35b facing the air flow from the connection port 35f to the exhaust hole 35b are arranged in parallel in the left-right direction on the upper surface 35c and the lower surface 35d of the amplification nozzle 35.

  High-pressure air flowing into the amplification nozzle 35 from the connection port 35f is guided to the exhaust hole 35b. At this time, ambient air is sucked from the intake hole 35a, the flow rate is amplified, and high-pressure air A2 is sent from the exhaust hole 35b.

  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 to-be-washed vehicle CA to a predetermined washing start position. Then, the car wash machine main body 1 straddles the vehicle to be cleaned CA and reciprocates with respect to the vehicle to be cleaned CA to start the car wash. Thereby, the shape of the vehicle CA to be cleaned is detected by the vehicle shape sensor 9 and the top brush 4, the side brush 5 and the rocker brush 6 are cleaned.

  When the cleaning of the vehicle to be cleaned CA is completed, the air to be cleaned is dried by sending air from the side blowing nozzle 22, the top blowing nozzle 21, and the amplification nozzle 35 toward the vehicle to be cleaned CA. The side blowing nozzle 22 sends air toward the side surface of the vehicle CA to be cleaned. The top blowing nozzle 21 sends air toward the front and rear surfaces and the upper surface of the vehicle CA to be cleaned. The amplifying nozzle 35 sends out air toward the rear surface of the vehicle CA to be cleaned.

  FIG. 6 is a side view showing the history of the top blowing nozzle 21 during drying. The figure shows a case where a to-be-cleaned vehicle CA having a rear spoiler CA1 is dried. When the vehicle to be cleaned CA is dried, the top blow nozzle 21 advances from the front to the rear of the vehicle to be cleaned CA as indicated by an arrow E1 as the car wash machine body 1 moves, and sends air A1 downward. To do.

  When the top blowing nozzle 21 is arranged at the rear end of the vehicle to be cleaned CA based on the detection result of the vehicle shape sensor 9, the top blowing nozzle 21 descends along the rear surface of the vehicle to be cleaned CA. As a result, the rear surface of the vehicle to be cleaned CA is dried.

  At this time, a high pressure air is supplied to the amplification nozzle 35 by opening the electromagnetic valve, and the high pressure air A2 is sent forward. Thereby, the water droplet in the recessed part which faced the downward direction of rear spoiler CA1, the circumference | surroundings of license plate CA2, etc. can be removed. Further, the water droplets scattered on the rear surface of the vehicle CA to be cleaned by the amplification nozzle 35 are caused to flow downward by the air A1 sent from the top blowing nozzle 21.

  The vehicle shape sensor 9 detects the rear spoiler CA1, supplies air to the amplification nozzle 35 when the exhaust hole 35b of the amplification nozzle 35 faces below the rear spoiler CA1, and stops supplying air when it leaves the rear spoiler CA1. Also good. Similarly, when the exhaust hole 35b of the amplification nozzle 35 faces the periphery of the license plate CA2, the air is supplied to the amplification nozzle 35, and the supply of air may be stopped when it leaves the license plate CA2.

  That is, air may be sent from the amplifying nozzle 35 to a predetermined area where it is difficult to remove water droplets by the top blowing nozzle 21, and the air supply may be stopped outside the predetermined area. Thereby, the drive time of a compressor is shortened and the running cost of the car wash machine WA can be reduced.

  Thereafter, the blowing from the top blowing nozzle 21 and the side blowing nozzle 22 is stopped, and the car wash ends.

  According to the present embodiment, a top blowing nozzle 21 (first blowing nozzle) that moves up and down to send air downward, and an amplification nozzle that is attached to the top blowing nozzle 21 and sends air at a higher pressure than the top blowing nozzle 21 forward. 35 (second blower nozzle). Thereby, high-pressure air is sent forward from the amplification nozzle 35, and water droplets in the recesses facing the rear of the vehicle to be cleaned CA can be removed. Therefore, the drying capacity of the car wash machine WA can be improved.

  Further, since the amplifying nozzle 35 sucks ambient air by supplying high-pressure air and amplifies the flow rate, the amount of air sent toward the vehicle to be cleaned CA increases, and the drying capacity can be further improved.

  In addition, a hose 37 that connects the amplification nozzle 35 and the air tank 38 is disposed in a flexible duct 32 that connects the top blowing nozzle 21 and the blower 20. Thereby, when the top blowing nozzle 21 moves up and down, the hose 37 can be prevented from being damaged by sliding between the car wash machine body 1 and the hose 37.

  Further, when the rear surface of the vehicle to be cleaned CA is dried, the amplifying nozzle 35 sends out air to a predetermined area such as the lower surface of the rear spoiler CA1 or around the license plate CA2, and stops sending air by the amplifying nozzle 35 outside the predetermined area. May be. Thereby, the drive time of a compressor can be shortened and the running cost of the car wash machine WA can be reduced.

Second Embodiment
Next, a second embodiment will be described. In the present embodiment, the operation of the top blow nozzle 21 is different from that of the first embodiment. Other parts are the same as those in the first embodiment. FIG. 7 is a side view showing the history of the top blowing nozzle 21 during drying. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS.

  The top blower nozzle 21 is supported by a horizontal axis with respect to an elevating device (not shown), and is arranged so as to be tiltable in the front-rear direction by driving an air cylinder (not shown).

  Thereby, the top blowing nozzle 21 sends air downward when the upper surface of the vehicle CA to be cleaned is dried, and tilts the injection direction forward when the rear surface is dried. Thereby, air is sent out from the blower port 21a toward the diagonally downward front, and the drying ability of the rear surface of the vehicle CA to be cleaned can be improved.

  Further, the amplification nozzle 35 sends the air A1 forward and upward due to the inclination of the top blowing nozzle 21. For this reason, the lower surface of rear spoiler CA1 and the circumference of license plate CA2 can be dried more reliably.

  The top blow nozzle 21 may be swung back and forth when the rear surface of the vehicle CA to be cleaned is dried. Thereby, the rear surface of the to-be-cleaned vehicle CA can be dried more reliably.

  According to this embodiment, the same effects as those of the first embodiment can be obtained. Further, when the rear surface of the vehicle to be cleaned CA is dried, the top blowing nozzle 21 is inclined forward, and the amplifying nozzle 35 (second blowing nozzle) sends air forward and upward. Thereby, the rear surface of the to-be-cleaned vehicle CA including the lower surface of the rear spoiler CA1 can be dried more reliably.

  Further, when the top blowing nozzle 21 swings in the front-rear direction when the rear surface of the vehicle CA to be cleaned is dried, the rear surface of the vehicle CA to be cleaned can be dried more reliably.

  In 1st, 2nd embodiment, the ventilation pipe 36 may be attached to the wall surface facing the entrance surface 1a of the car wash machine main body 1 on the top ventilation nozzle 21, and air may be sent out from the amplification nozzle 35 toward back. Thereby, when the front surface of the vehicle CA to be cleaned is dried, water droplets around the license plate CA2 and in the grill can be surely removed. That is, by sending air in the front-rear direction from the amplification nozzle 35, it is possible to improve the drying capability of the front or rear surface of the vehicle CA to be cleaned.

  According to this invention, it can utilize for the car wash machine provided with the ventilation nozzle.
