First, as the car wash machine body 1 moves forward, high-pressure water is discharged from the high-pressure water nozzle 11 to wash out sand and mud on the upper surface of the automobile for the first high-pressure washing (first forward step).
When it is detected that the first high-pressure washing reaches the rear end of the vehicle on the basis of the signals from the rotary encoder 16 and the detector 17, the discharge of the high-pressure water and the traveling of the main body 1 are stopped, and the first high-pressure washing is finished.

Subsequently, the main body 1 goes back, and high-pressure water is discharged from the high-pressure water nozzles 12 to perform a second high-pressure washing to wash away sand and mud on the side surface of the automobile (first returning step). When the second high-pressure washing reaches the front end of the automobile, this washing is stopped.

After this, the main body 1 again moves forward, and thereafter executes a normal car wash course. Detergent water foamed from the detergent nozzle 6 is discharged as the main body 1 travels, and the rotating brush 3
・ Activate step 4 to perform brush cleaning. As the main body 1 moves forward, the carriage 22 of the lower cleaning device 20 simultaneously moves forward, discharging high pressure water from the lower cleaning nozzle 27 to perform lower cleaning (second forward process).

When the brush cleaning and the lower cleaning reach the rear end of the automobile, the cleaning is stopped. After this, the main body 1 is moved back and the rinsing water is discharged from the water-only nozzle 5 to operate the rotary brushes 3, 4 and 4 to continue brush cleaning.
Along with this, the trolley 22 also goes back, and the lower cleaning nozzle 27
More water is discharged and the lower part cleaning is repeated (second returning step).

When the brush cleaning and the lower part cleaning are completed, the main body 1 moves to the third outward trip, and the nozzles 5 and 8 dedicated to water are used.
Waxing is performed by operating the rotary brushes 3, 4 and 4 while spraying more rinse water and wax water from the wax nozzle 7, respectively (third forward step).

When the waxing is completed, the main body 1 is further moved back and the blower nozzles 9, 10 and 10 are operated to measure the drying of the automobile (third returning process), and the series of car washing is finished.

As described above, in this embodiment, when the car wash accompanied by the input of the high pressure washing key 75 is executed, the high pressure water nozzle 11 performs the high pressure washing of the upper surface of the vehicle body with the first traveling of the main body 1. At the time of the subsequent return trip, high-pressure water nozzles 12 and 12 perform high-pressure cleaning on the side surface of the vehicle body, and then normal course car-washing is executed. As a result, the high-pressure water from the high-pressure pump 32 can be concentrated on the upper surface and the side surfaces of the vehicle body, respectively, and the sand and mud on the vehicle body can be reliably removed before the course car wash involving brush cleaning. In addition, the high pressure pump 32
Is used not only for the above-mentioned high-pressure cleaning, but also for cleaning the lower part of the vehicle body by the lower cleaning device 20 in the subsequent steps, and for supplementary cleaning of the tire part and the like using the gun nozzle 13 after car cleaning, which is effectively utilized.

In the above embodiment, "high pressure cleaning of the upper surface of the vehicle body"-"high pressure cleaning of the side surface of the vehicle body"-"normal car wash course" are carried out in this order. High-pressure cleaning "may be performed in this order.

[0032]

As is apparent from the above embodiment, the present invention is performed by the high-pressure pump because the upper surface cleaning and the side surface cleaning of the automobile body are separately performed when the car washer is moving forward and when it is returning. The high-pressure water can be concentrated on the upper surface or the side surface, and even a small pump with a limited discharge amount can obtain a high cleaning effect and can be constructed at low cost. In addition, the high-pressure cleaning is completed in a unit process in which the car wash machine reciprocates once, and after that, it is sufficient to continue brush cleaning as is conventionally done, and the high-pressure cleaning can be performed without making a large change to the operation program of the existing car wash machine. A cleaning function can be added.
