Description

  The present invention is installed in a gas station, for example, and is used for car washing, in particular, blows wind on the upper surface of the vehicle to be cleaned to scatter and discharge water droplets adhering to the vehicle to be cleaned (the vehicle to be cleaned). It relates to the top nozzle (which dries).

  Conventionally, the following configuration has been provided for discharging water droplets from a location where it is difficult to discharge water droplets on the outer surface of the vehicle to be cleaned. That is, the top nozzle and a side nozzle that blows wind on both sides of the vehicle to be cleaned are provided in the car wash machine body, and these nozzles communicate with the blower device, and the upper high pressure nozzle that faces downward near the top nozzle In addition, an inward side high-pressure nozzle is provided near the side nozzle, and these high-pressure nozzles communicate with a high-pressure air source via an electromagnetic valve. And in the part where it is difficult to remove the water droplets, the high pressure air from the high pressure air source is sent to each high pressure nozzle by opening the solenoid valve for a set time based on the pre-programmed control, thereby the upper high pressure nozzle High pressure air is sprayed to the upper specific portion through the side high pressure air, and high pressure air is sprayed to the side specific portion through the side high pressure nozzle, so that water droplets of each specific portion are scattered and discharged (for example, , See Patent Document 1).

In conventional car wash machines, the top nozzle is raised in parts of the vehicle to be cleaned that are equipped with equipment (side mirror, rear mirror, carrier, rear spoiler, etc.) to avoid contact between the top nozzle and these equipment. In addition, the direction of the top nozzle (the direction of the blown air) is changed on the front and rear surfaces of the vehicle to be cleaned, and the wind is sent to a portion where the wind cannot be blown from above to improve the drying efficiency (for example, Patent Literature 2).
