[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car washing apparatus for sequentially carrying out processes such as washing, wax application and drying on a vehicle conveyed in a tunnel-shaped frame.

[0002]

2. Description of the Related Art Conventionally, a car washing apparatus of this type applies a rotating brush to a vehicle conveyed in a frame formed in a tunnel shape on a surface of the vehicle to wash the vehicle and apply wax, and then a nozzle is used. Drying to remove water droplets attached to the vehicle by blowing high-pressure air toward the vehicle has been performed sequentially, and multiple vehicles can be washed continuously.
It is characterized by high operating efficiency.

[0003]

As described above, the conventional car washing apparatus can efficiently wash the car when there are a plurality of car washes, but hasten the car washing when there is only one car because there is no following car. There was a demand that there was no need to at least sufficiently dry the vehicle. The present invention has been made to address such a problem, and has as its object to reduce the transport speed of a vehicle when one vehicle is transported in a drying process and sufficiently dry the vehicle.

[0004]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention provides a method of sequentially cleaning and drying a plurality of vehicles conveyed in a frame formed in a tunnel shape. In a car wash device for continuously washing vehicles,
Determining means for determining whether or not one vehicle is conveyed in a drying step for removing water droplets adhered to the vehicle after washing the vehicle; and determining whether or not the number of vehicles determined by the determining means is one vehicle. And control means for reducing the transport speed of the sheet.

The vehicle conveyed by the conveyor 2 is washed,
The vehicle proceeds in the order of the wax application, and when the value of the counter of the central control unit 24 reaches a predetermined value, that is, when the traveling position of the vehicle reaches the front end of the fourth frame 1d, the central control unit 24 executes the vehicle washing. The central control unit 2 determines whether or not one
In the case where the number of vehicles processed in step 4 is plural, the speed of the conveyor 2 is operated at the same speed, and in the case of one vehicle, the speed of the conveyor 2 is reduced and blown out from each of the nozzles 15, 16 and 16. The supply time of the high-pressure air to be supplied is made longer than usual, so that the vehicle is dried slowly and the vehicle is completely drained.
