When the cleaning key 44 is input and used alone, only the lower cleaning key 44 is input and the start key 45 is pressed.

  The input device 38 includes a start setting key 47 for setting the injection start position of the carriage 10 and a stop setting key 48 for setting the injection stop position of the carriage, and manually inputs the injection range of the lower cleaning device. The input device 38 is connected to the central control unit 30 of the main body 1, and the user inputs each key at a position away from the car wash machine main body 1 (a position where the traveling of the lower cleaning device can be visually recognized). The injection range is set. The input of each key 47, 48 is transmitted to the central control unit 30 and registered in the memory together with the traveling position of the carriage.

Hereinafter, the car wash operation of the car wash machine according to the first embodiment configured as described above will be described. First, the case where the car washing course and the lower part washing are used together will be described with reference to FIG.
When it is detected that the car is stopped at a predetermined stop position in the state (a) in which the car wash machine body 1 is in the standby position, the operation panel 37 is ready for reception. When the car wash starts, the side brushes 4 and 4 are closed in the car wash machine 1 and the car wash machine main body 1 and the carriage 10 are moved forward. When the main body 1 reaches the position (b) where the vehicle shape detection device 7 detects the front end of the vehicle as the vehicle travels, the water supply unit 18 of the lower cleaning device is actuated to release water or liquid solution from the injection nozzle 12. Begin cleaning the bottom.

  The car wash machine main body 1 drives the upper surface brush 3 and the side brushes 4 and 4 to clean the left and right side surfaces and the upper surface of the vehicle body along the vehicle body detected by the vehicle shape detection device. When the position reaches the position (c) at which the rear end of the vehicle is detected in 7, the water supply from the water supply section 18 of the lower cleaning device is stopped and the water discharge from the injection nozzle 12 is stopped. Further, when the car wash machine main body 1 reaches the travel limit position (d) of the rails 2 and 2, the travel of the main body 1 and the carriage 10 is stopped, and the outward car wash process is terminated. The car wash machine of the type of the car wash machine 1 can selectively execute a car wash course with different number of steps such as a car wash course that is normally completed in one round trip and a car wash course that is completed in two round trips. If there is, the air is blown back to the vehicle body from the blower nozzles 5, 6, 6 and dried after the above steps. At this time, the carriage 10 returns without discharging water. On the other hand, in the case of two reciprocating vehicles, the cleaning including the lower portion cleaning similar to the above step is performed while returning, and the reciprocating cleaning is performed. In the second outward and second backward steps, the lower cleaning device Do not work. The washing water discharged from the lower washing device may be either water or a rust inhibitor aqueous solution, but in this embodiment, only the rust preventive aqueous solution is released during one reciprocating car wash, and during two reciprocating car wash during the outbound trip. The aqueous solution is discharged at the time of water and return.

  As described above, in the car wash in which the car wash course and the lower part wash are performed in parallel, the lower wash water is always discharged within the main body of the car wash machine, so that it does not splash outside.

Next, the case of performing only the lower cleaning will be described with reference to FIG.
The lower cleaning course is executed when the lower cleaning key 44 on the operation panel 37 is selected and the start key 45 is input. When the lower cleaning starts, the cleaning range is first set at the first outbound time. Here, since the lower cleaning device does not have a function of detecting the shape of the automobile, the user sets the input device 38 manually.

  In this cleaning range setting step, the carriage 10 is run at a higher speed than usual, and the cleaning water is discharged from the spray nozzle 12 at a low pressure. This is for the purpose of shortening the set time, confirming that the water supply system is operating normally, and preventing splashing of washing water to the surroundings, and it is desirable that the fountain power be below the hood of the passenger car.

  When the user confirms that the carriage 10 has traveled from the standby position (a) and the carriage 10 has traveled to the position (b) where the water discharged from the injection nozzle 12 hits the lower part of the automobile, the start setting key 47 of the input device 38 is used. To set the injection start position. In response to this input, the central controller 30 extracts the travel position of the carriage 10 detected by the carriage position detector 36 and stores the position in the memory as the injection start position. When the user visually confirms that the carriage 10 has reached the position (c) where the water discharge from the injection nozzle 12 does not hit the lower part of the automobile as the carriage 10 travels, this time, the stop setting key 48 of the input device 38 is displayed. And the travel position of the carriage 10 at that time is stored in the memory as the injection stop position.

  Thus, when the washing range is set, the lower washing after the first return slows the traveling of the carriage, and high-pressure washing water is discharged from the injection nozzle 12 in the set washing range. Thus, the lower cleaning device discharges the cleaning water at a high pressure only to the bottom surface of the automobile, and does not scatter around.

  Thus, in the car wash machine of the present invention, it is possible to prevent the washing water from being scattered around when the car wash machine main body and the lower washing apparatus are run together or when only the lower washing apparatus is run alone. Is.

  Subsequently, another embodiment of the present invention will be described. In this apparatus, a point setting key 49 and a water pressure setting key 50 are provided on the input device 38 ', and the other configurations are the same as those in the first embodiment.

Hereinafter, in Example 2, the case where only the lower part cleaning is executed will be described with reference to FIG.
Similarly to the first embodiment, this apparatus also sets a cleaning range at the time of the first going. However, in this cleaning range setting step, a plurality of feature points in the automobile are arbitrarily set by the input device 38 ′. The specified feature point setting and the water pressure setting for setting the water pressure between the set feature points are performed.

  As the carriage travels, every time the carriage 10 reaches the part of the automobile desired by the user, the point setting key 49 of the input device 38 'is input to set the feature points. FIG. 6 shows a state in which the front end a of the automobile, the rear end b of the front tire house, the front end c of the rear tire house, and the rear end d of the automobile are set. The central control unit 30 extracts the cart traveling position of each set feature point and stores the position in the memory. When the cart 10 reaches the travel limit and the first travel ends, the travel of the cart 10 is temporarily stopped, and a screen representing the set feature points is displayed on the display unit 42 of the operation panel 37.

Next, while observing this screen, the water pressure of the washing water discharged from the spray nozzle 12 between each feature point is set using each key of the input device 38 ′. FIG. 7 shows a setting screen for water pressure setting.
First, when the point setting key 49 is input, the set feature point a blinks as shown in FIG. Thereafter, every time the point setting key 49 is input, “feature point b → c → d → a. . . Can be switched. When the water pressure setting key 50 is input while the feature point a is blinking, water is discharged from the injection nozzle 12 until the carriage 10 reaches the feature point b from the feature point a as shown in FIG. The water pressure can be selected. The type of water pressure can be selected from three stages of “water discharge stop-low pressure-high pressure”, and is switched every time the water pressure setting key 49 is input. Here, a setting is made to clean between a and b at a high pressure.

  In the same procedure, the feature point b blinks to set the water pressure when traveling between bc, the feature point c blinks and the water pressure when traveling between cd is set, and the feature point d blinks. Then, the water pressure when traveling from the feature point d to the cart travel limit is set. In addition, the water discharge is stopped while the vehicle travels from the carriage standby position to the first feature point (here, point a).

  Thus, when the feature point setting and the water pressure setting are made, the lower cleaning after the first return will slow down the traveling of the carriage and the specified cleaning range will be discharged with the specified water pressure. As a result, the user can arbitrarily set a portion that the user wants to wash intensively or a portion that does not want high-pressure washing water to be poured.
