The top blowing nozzle 21 is provided in the ceiling portion 91 and blows air toward the upper surface of the vehicle CA to be cleaned.

  FIG. 3 is a flowchart showing the operation of the car wash machine main body 1 of the car wash machine WA. The blocking member 99a in the blocking state shifts to the retracted state when the car wash acceptance is completed, and the vehicle to be cleaned CA moves forward. When the vehicle CA to be cleaned stops at a predetermined position, cleaning by the cleaning unit is started in step S1. When the washing is started, as shown in FIG. 4, the car wash machine body 1 moves from the car wash start position T1 toward the rear of the vehicle CA to be washed as shown by an arrow E1. The car wash machine main body 1 cleaned to the rear end of the vehicle to be cleaned CA is inverted as indicated by an arrow E2, and the vehicle CA to be cleaned is cleaned by reciprocating movement.

  When the car wash machine main body 1 returns to the car wash start position T1 at the time of washing, the car wash machine body 1 is reversed and moved in the direction of the arrow E1 to be dried by the drying unit. When the car wash machine body 1 is dried to the rear end of the vehicle CA to be cleaned, the car wash is finished. When the to-be-washed vehicle CA exits, the car wash machine main body 1 reverses and moves in the direction of the arrow E2, and returns to the car wash start position T1. Normally, the car wash machine main body 1 moves at a predetermined standard speed at the time of washing, drying and returning. The standard speed may be different during washing, drying and returning.

  In step S2, it is determined whether or not the cleaning is completed. When the cleaning is completed, the process proceeds to step S3. In step S <b> 3, it is determined whether or not the subsequent car to be cleaned CA has been accepted. If the next car to be cleaned CA has not been accepted, the process proceeds to step S6, and if it has already been performed, the process proceeds to step S4.

  In step S4, it is determined whether or not the water storage tank 100 is in a drought danger state. The drought danger state refers to a state where there is a possibility of drought in the water storage tank 100 when the vehicle to be cleaned CA is subsequently washed. The water storage tank 100 is full before the car wash machine main body 1 returns to the car wash start position T1 based on the amount of wash water discharged from the washing section for the previous vehicle to be cleaned CA currently being washed and the water supply speed of the water storage tank 100. If the condition is not reached, it is determined that the drought is in danger.

  At this time, the values stored in the storage unit 8a are used for the amount of wash water discharged from the vehicle to be cleaned CA and the water supply speed of the water storage tank 100. Further, the time until the car wash machine main body 1 returns to the car wash start position T1 is derived from the moving speed of the car wash machine main body 1 and the exit time of the vehicle to be cleaned CA. The standard time memorize | stored in the memory | storage part 8a is used for the leaving time of the to-be-cleaned vehicle CA.

  If it is determined that the water storage tank 100 is not in a drought risk state, the process proceeds to step S6, and if it is determined to be a drought risk condition, the process proceeds to step S5. In step S5, the moving speed of the car wash machine main body 1 at the time of drying is set to a deceleration speed that is lower than the standard speed. The deceleration speed is set to a speed at which the water storage tank 100 becomes full before the car wash machine body 1 returns to the car wash start position T1.

  In step S6, the car wash machine main body 1 moves rearward of the vehicle to be cleaned CA as indicated by an arrow E1, and drying by the drying unit is performed. In step S7, it is determined whether or not the drying is finished. When the car wash machine main body 1 is disposed at the car wash end position T2 where the car wash machine body 1 has been dried to the rear end of the car CA to be cleaned, the process proceeds to step S8.

  In step S8, the notification unit instructs to leave the vehicle CA to be cleaned. In step S9, the vehicle to be cleaned CA moves forward and waits until it exits from the exit surface of the car wash machine main body 1. When the vehicle to be cleaned CA exits, the process proceeds to step S20. In step S20, the car wash machine body 1 moves from the car wash end position T2 in the direction of arrow E2 at the standard speed and returns to the car wash start position T1. As a result, the car wash is completed, and the subsequent car to be cleaned CA is washed.

  Note that when it is determined that the drought is in danger, the moving speed at the time of returning to the car wash start position T1 of the car wash machine main body 1 may be decelerated from the standard speed. Further, when it is determined that the drought is in a dangerous state, the moving speed of the car wash machine main body 1 at the time of drying and returning may be reduced from the standard speed.

  According to the present embodiment, the water supply speed of the water storage tank 100 and the amount of wash water discharged according to the car wash conditions are stored, and the next car to be washed is received when the next car to be washed CA is received before the car wash is completed. It is determined whether or not the vehicle CA is in a drought danger state. And if it is judged that it is a drought danger state, the moving speed of the car wash machine main body 1 after completion | finish of washing | cleaning will be decelerated. Thereby, without providing a water level sensor, drought at the time of washing the vehicle to be washed CA can be prevented to reduce the cost of the car wash machine WA, and the car wash machine main body 1 is not accelerated at the time of washing, thereby preventing a reduction in washing power. it can. In addition, it is possible to prevent the driver of the vehicle CA to be cleaned later in a drought danger state from feeling the standby state due to the water supply of the water storage tank 100, and to prevent the convenience of the car wash machine WA from being lowered.

  In addition, before the previous vehicle to be cleaned CA is dried, the exit time of the vehicle to be cleaned CA is set to a prestored standard time to determine whether or not it is in a drought danger state. And since the moving speed of the car-washing machine main body 1 at the time of drying of the previous to-be-washed vehicle CA is decelerated in the drought danger state, the car wash machine WA that can prevent drought can be easily realized. Moreover, the drying capacity of the previous vehicle to be cleaned CA can be further improved.

  It should be noted that the capacity of the water storage tank 100 may be stored in the storage unit 8a by input of a car wash staff or the like. As a result, the remaining water amount of the water storage tank 100 can be derived from the amount of water discharged from the washing water to the previously cleaned vehicle CA and the capacity of the water storage tank 100. For this reason, in step S4, when the amount of water stored in the water storage tank 100 reaches the amount of water discharged from the later-to-be-cleaned vehicle CA before the car wash main body 1 returns to the car wash start position T1, it is not a drought danger state. You may judge. Thereby, the car wash machine main body 1 can move at a standard speed during drying to shorten the car wash time, and can prevent drought of the water storage tank 100 when the car to be washed CA is subsequently washed.

  In this embodiment, you may decelerate the moving speed of the car-washing machine main body 1 from the middle of drying. When the car wash machine body 1 is decelerated when the car wash machine body 1 is returned, the car wash machine body 1 may be decelerated from the middle of the return. Moreover, although the car wash machine main body 1 makes 1.5 reciprocations to perform car wash by the washing unit and the drying unit, it may be a car wash machine that makes 0.5 car reciprocations (only the outward path) to wash the car.

(Second Embodiment)
FIG. 5 is a flowchart showing the operation of the car wash machine WA of the second embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the drought risk condition is determined after the vehicle to be cleaned CA leaves the first embodiment. Other parts are the same as those in the first embodiment.

  As in the first embodiment, cleaning of the vehicle CA to be cleaned is started in step S1. When the cleaning is completed, drying of the vehicle to be cleaned CA is started in step S6. When the drying is completed, the vehicle to be cleaned CA waits for exit (step S9), and when the vehicle to be cleaned CA exits, the process proceeds to step S10.

  In step S10, it is determined whether or not the next car to be cleaned CA has been received. If the next vehicle to be cleaned CA has not been received, the process proceeds to step S20, and if it has already been performed, the process proceeds to step S11.

  In step S11, it is determined whether or not the water storage tank 100 is in a drought danger state. At this time, the exit time of the vehicle to be cleaned CA included in the time until the car wash machine main body 1 returns to the car wash start position T1 is used because the vehicle to be cleaned CA has already exited. For this reason, the exact water supply time with respect to the water storage tank 100 can be derived | led-out rather than 1st Embodiment.

  If it is determined that the water storage tank 100 is not in a drought risk state, the process proceeds to step S20, and if it is determined to be a drought risk condition, the process proceeds to step S12. In step S12, the moving speed when the car wash machine body 1 returns from the car wash end position T2 to the car wash start position T1 is set to a deceleration speed that is decelerated from the standard speed. The deceleration speed is set to a speed at which the water storage tank 100 becomes full before the car wash machine body 1 returns to the car wash start position T1.

  In step S20, the car wash machine main body 1 returns from the car wash end position T2 to the car wash start position T1. As a result, the car wash is completed, and the subsequent car to be cleaned CA is washed.

  According to the present embodiment, the moving speed when the car wash machine main body 1 returns is decelerated during a drought danger state. Thereby, there can exist an effect similar to 1st Embodiment.

  In addition, since it is determined whether or not the drought risk condition is present after the previous vehicle to be cleaned CA has exited, the water supply amount can be grasped more accurately.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine and car wash method which wash | clean a to-be-washed vehicle with the wash water supplied from a water storage tank.
