このように、被洗浄車両２の汚れが目立つとき、あるいは色が薄色のとき選択する選択スイッチである「コースＩ」スイッチ６１が選択されると、１回目の水洗いおよびブラッシングの後、十分な乾燥が行われ、被洗浄車両２の表面が乾いている状態で洗剤アーチ７，１０より水垢除去剤が噴霧される。よって、被洗浄車両２の表面に水分が殆どないため、水垢除去剤の濃度はほとんど変化せず、水垢除去剤は噴霧されたそのままの濃度により被洗浄車両２の水垢が洗い落とされる。したがって、水垢除去剤に強い薄色（特に白色）の被洗浄車両２のとき、あるいは汚れが目立つ被洗浄車両２のとき、濃度を落とさずに水垢除去剤を噴霧することにより、水垢を十分に洗い落とすことができる。
【００４０】
また、被洗浄車両２の色が濃色のとき選択する選択スイッチである「コースＩＩ」スイッチ６２が選択されると、１回目の水洗いおよびブラッシングの後、すぐに被洗浄車両２の表面が濡れている状態で洗剤アーチ７，１０より水垢除去剤が噴霧される。よって、水垢除去剤は、表面に残った水分のために薄まり、濃度が低くなって被洗浄車両２の水垢が洗い落とされる。したがって、水垢除去剤に弱い濃色の被洗浄車両２のとき、水垢除去剤の濃度が薄くなることにより、水垢除去剤の被洗浄車両２へのダメージを弱めることができる。
【００４１】
なお、本発明の実施の形態では、選択スイッチ６１〜６３により、ユーザー、あるいは作業員が液剤の濃度を選択しているが、洗車機本体１に被洗浄車両２の色を検出する色センサを設け、この色に応じて、濃色または薄色（特に白色）を判断し、液剤の濃度を選択するようにしてもよい。
【００４２】
また液剤として、水垢除去剤を例としているが、被洗浄車両２に噴霧される液剤に全て適用することができる。
【００４３】
【発明の効果】
以上のように本発明によれば、被洗浄車両の色が濃色のとき、被洗浄車両のブラッシング洗浄の後、すぐに被洗浄車両の表面が濡れている状態でスプレー装置により液剤が噴霧されることによって、液剤の濃度を薄くでき、液剤の被洗浄車両へのダメージを弱くできる。また被洗浄車両の汚れが目立つとき、あるいは色が薄色のとき、被洗浄車両のブラッシング洗浄に続く乾燥の後にスプレー装置により同液剤、すなわち被洗浄車両の色が濃色のときに使用（噴霧）されたものと同じ液剤を噴霧することによって、液剤の濃度をほとんど変化せずに液剤を噴霧でき、液剤の濃度のままに被洗浄車両を洗浄できる。

The solenoid valves 28 and 29 are opened to spray the rinse from the first wash water arch 6 and the second wash water arch 9 (step-26), and a forward command is output to the traveling drive device 53 to move the car wash machine body 1 forward. (Step-27).
[0032]
As the car washer body 1 travels, rinse is sprayed from the first wash water arch 6 and the second wash water arch 9 and the top brush 15 and the side brush 16 brush the vehicle 2 to be washed.
[0033]
Then, when it is confirmed by the limit switch 20 that the car wash body 1 has reached the travel end position (step-28), a stop command is output to the travel driving device 53 to stop the car wash machine body 1 (step-28). 29), a stop command is output to the drive device of the top brush 15 and the side brush 16, and the top brush 15 and the side brush 16 are stopped (step -30).
[0034]
Thus, when the car wash machine body 1 reaches the traveling end position, the car wash machine body 1 stops, and the brushing of the vehicle 2 to be washed by the top brush 15 and the side brush 16 is stopped.
"3rd return trip"
The solenoid valves 46 and 47 are opened to spray the wax base material from the wax base material arch 22 (step-31), and a reverse command is output to the traveling drive device 53 to move the car wash machine body 1 backward (step-32).
[0035]
As the car washer body 1 travels, the rinse is continuously sprayed from the first wash water arch 6 and the second wash water arch 9, and the wax base material is sprayed from the wax base material arch 22.
[0036]
Then, when it is confirmed by the limit switch 19 that the car washer body 1 has reached the traveling start position (step-33), a stop command is output to the traveling drive device 53 to stop the car washer body 1 (step-33). 34), the solenoid valves 46 and 47 are closed to stop the spraying of the wax base material from the wax base material arch 22 (step-35), and the solenoid valves 28 and 29 are closed to close the first cleaning water arch 6 and the second cleaning. The spraying of the rinse from the water arch 9 is stopped (step-36).
[0037]
Thereby, when the car wash machine body 1 reaches the traveling start position, the car wash machine body 1 stops, the spraying of the wax base material from the wax base material arch 22 is stopped, and the first wash water arch 6 and the second wash water. The spraying of the rinse from the arch 9 is stopped.
[0038]
When the "course II" switch 62 is selected as the car wash course, the steps of "first return path" and "second outward path" are deleted, and the drying step is deleted. When the "course III" switch 63 is selected as the car wash course, the steps of "first return path" to "third forward path" are deleted.
[0039]
As described above, when the "course I" switch 61, which is a selection switch for selecting when the stain on the vehicle 2 to be washed is conspicuous or the color is light, is selected after the first washing and brushing. Drying is performed, and a descaling agent is sprayed from the detergent arches 7 and 10 while the surface of the vehicle 2 to be washed is dry. Therefore, since there is almost no moisture on the surface of the vehicle 2 to be washed, the concentration of the descaling agent hardly changes, and the scale of the vehicle 2 to be washed is washed off by the concentration of the sprayed agent as it is sprayed. Therefore, in the case of a light-colored (especially white) washed vehicle 2 that is strong against the descaling agent, or in the case of the washed vehicle 2 where dirt is conspicuous, the scale is sufficiently sprayed by spraying the descaling agent without decreasing the concentration. Can be washed off.
[0040]
When the "course II" switch 62, which is a selection switch to be selected when the color of the vehicle 2 to be washed is dark, is selected, the surface of the vehicle 2 to be washed becomes wet immediately after the first washing and brushing. The descaling agent is sprayed from the detergent arches 7 and 10 in the state of being in the state. Therefore, the descaling agent is diluted due to the moisture remaining on the surface, and the concentration becomes low, and the scaling of the vehicle 2 to be washed is washed away. Therefore, when the vehicle 2 is a deep-colored vehicle that is weak against the descaling agent, the concentration of the descaling agent is reduced, so that damage to the vehicle 2 due to the descaling agent can be reduced.
[0041]
In the embodiment of the present invention, the user or the worker selects the concentration of the liquid agent by using the selection switches 61 to 63. However, the car wash machine body 1 is provided with a color sensor for detecting the color of the vehicle 2 to be washed. A dark or light color (particularly white) may be determined according to the color, and the concentration of the liquid material may be selected.
[0042]
Although the descaling agent is taken as an example of the liquid agent, the present invention can be applied to all liquid agents sprayed on the vehicle 2 to be cleaned.
[0043]
【The invention's effect】
As described above, according to the present invention, when the color of the vehicle to be cleaned is dark, after the brushing cleaning of the vehicle to be cleaned, the liquid agent is immediately sprayed by the spray device while the surface of the vehicle to be cleaned is wet. As a result, the concentration of the liquid agent can be reduced, and the damage of the liquid agent to the vehicle to be cleaned can be reduced. Also, when the stain on the vehicle to be washed is conspicuous, or when the color of the vehicle to be washed is light, the same liquid agent, that is, when the color of the vehicle to be washed is dark, is used (spraying). By spraying the same liquid agent as described above, the liquid agent can be sprayed with almost no change in the concentration of the liquid agent, and the vehicle to be cleaned can be washed with the concentration of the liquid agent unchanged.
