The 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 taken in from the intake hole 35a, the flow rate is amplified, and high-pressure air A2 is sent out from the exhaust hole 35b.

In the car wash machine WA having the above configuration, the user drives and stops the vehicle CA to be washed in front of the remote panel 7, and sets the car wash conditions of the vehicle CA to be washed from within the vehicle CA to be washed.

After setting the car wash conditions, the user moves the car to be washed CA to a predetermined wash start position. Then, the car wash machine main body 1 reciprocates with respect to the vehicle to be washed CA across the vehicle to be washed CA, and the car wash is started. As a result, the shape of the vehicle CA to be cleaned is detected by the vehicle shape sensor 9, and cleaning is performed by the top brush 4, the side brush 5, and the rocker brush 6.

When the cleaning of the vehicle CA to be cleaned is completed, air is sent from the side blower nozzle 22, the top blower nozzle 21 and the amplification nozzle 35 toward the vehicle CA to be cleaned to dry the vehicle CA to be cleaned. The side blower nozzle 22 sends air toward the side surface of the vehicle CA to be cleaned. The top blower nozzle 21 sends air toward the front and rear surfaces and the upper surface of the vehicle CA to be cleaned. The amplification nozzle 35 sends air toward the rear surface of the vehicle CA to be cleaned.

When the vehicle CA to be washed dries, the top blower nozzle 21 advances from the front to the rear of the vehicle CA to be washed as shown by the arrow E1 as the car wash machine body 1 moves, and sends out air A1 downward. To do.

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

At this time, the solenoid valve is opened to the amplification nozzle 35 to supply high-pressure air, and high-pressure air A2 is sent forward. As a result, it is possible to remove water droplets in the recesses facing the rear such as below the rear spoiler CA1 and around the license plate CA2. Further, the water droplets scattered on the rear surface of the vehicle CA to be cleaned by the amplification nozzle 35 are flowed downward by the air A1 sent from the top blower nozzle 21.

The rear spoiler CA1 is detected by the vehicle shape sensor 9, and when the exhaust hole 35b of the amplification nozzle 35 faces below the rear spoiler CA1, air is supplied to the amplification nozzle 35, and when it is separated from the rear spoiler CA1, the air supply is stopped. May be good. Similarly, when the exhaust hole 35b of the amplification nozzle 35 faces the periphery of the license plate CA2, the amplification nozzle 35 may be supplied with air, and when the exhaust hole 35b is separated from the license plate CA2, the air supply may be stopped.

That is, air may be sent from the amplification nozzle 35 to a predetermined region where it is difficult for the top blower nozzle 21 to remove water droplets, and the delivery of air may be stopped outside the predetermined region. As a result, the driving time of the compressor can be shortened, and the running cost of the car wash machine WA can be reduced.

After that, the blowing from the top blowing nozzle 21 and the side blowing nozzle 22 is stopped, and the car wash is completed.

It is equipped with 35 (second blower nozzle). As a result, high-pressure air is sent forward from the amplification nozzle 35, and water droplets in the recess facing the rear of the vehicle CA to be cleaned can be removed. Therefore, the drying capacity of the car wash machine WA can be improved.

Further, since the amplification nozzle 35 takes in ambient air by supplying high-pressure air and amplifies the flow rate, the amount of air sent out to the vehicle to be cleaned CA is increased, and the drying capacity can be further improved.

Further, a hose 37 connecting the amplification nozzle 35 and the air tank 38 is arranged in a flexible duct 32 connecting the top blower nozzle 21 and the blower 20. As a result, when the top blower nozzle 21 moves up and down, damage to the hose 37 due to sliding between the car wash machine main body 1 and the hose 37 can be prevented.

Further, when the rear surface of the vehicle CA to be cleaned is dried, air is sent out by the amplification nozzle 35 to a predetermined area such as the lower surface of the rear spoiler CA1 and the periphery of the license plate CA2, and the air delivery by the amplification nozzle 35 is stopped outside the predetermined area. You may. As a result, the driving time of the compressor can be shortened and the running cost of the car wash machine WA can be reduced.

As a result, the top blower nozzle 21 sends out air downward when the upper surface of the vehicle CA to be cleaned is dried, and inclines the injection direction forward when the rear surface is dried. As a result, air is sent out from the air outlet 21a diagonally downward and forward, and the drying ability of the rear surface of the vehicle CA to be cleaned can be improved.

Further, the amplification nozzle 35 sends out the air A1 forward and upward due to the inclination of the top blower nozzle 21. Therefore, the lower surface of the rear spoiler CA1 and the periphery of the license plate CA2 can be dried more reliably.

The top blower nozzle 21 may be swung in the front-rear direction when the rear surface of the vehicle CA to be cleaned is dried. As a result, the rear surface of the vehicle CA to be cleaned can be dried more reliably.

According to the present embodiment, the same effect as that of the first embodiment can be obtained. Further, when the rear surface of the vehicle CA to be cleaned is dried, the top blower nozzle 21 is tilted forward, and the amplification nozzle 35 (second blower nozzle) sends air forward and upward. As a result, the rear surface of the vehicle to be cleaned CA including the lower surface of the rear spoiler CA1 can be dried more reliably.

Further, if the top blower 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 the first and second embodiments, the ventilation pipe 36 may be attached to the wall surface of the car wash machine main body 1 on the top blower nozzle 21 facing the inlet surface 1a, and air may be sent out from the amplification nozzle 35 toward the rear. As a result, water droplets around the license plate CA2 and in the grill can be reliably removed when the front surface of the vehicle CA to be cleaned is dried. That is, by sending air from the amplification nozzle 35 in the front-rear direction, the drying ability of the front surface or the rear surface of the vehicle CA to be cleaned can be improved.

According to the present invention, it can be used in a car wash machine equipped with a blower nozzle.
