  First, the control device 33 'confirms the presence or absence of the vehicle 2 to be washed after confirming the elapse of a preset time since the previous inspection (abnormality confirmation) of the spray device 5' (step-1). (Step-2) If there is no vehicle 2, the pump 53 is driven (Step-3). Creation of an ascending curve is started based on the water pressure in the main pipe 52 measured by the water pressure gauge 54 '(step -4), and when the ascending curve is completed (step -5), the water pressure in the created main pipe 52 is obtained.

If it is within the range, the primary side of the spray device 5 '(from the tank 40 to each of the branch pipes 41 to 44). It is determined that the solenoid valves 55 to 58 are normal (step -7). If the created upward curve is not within the range of the normal upward curve in Step-6, it is determined that the primary side of the spray device 5 'is abnormal (Step-8), and the main piping of the abnormality notification panel 35' is determined.

The nth solenoid valves 55a, 55b to 58 (for example, the first solenoid valve 55a) is opened (step -11). Then, the pump 53 is stopped (Step-12), and a descending curve is created based on the water pressure in the main pipe 52 measured by the water pressure gauge 54 '(Step-13). When the descending curve is completed (Step-13) -14), comparing the descending curve of the water pressure in the created main pipe 52 with the descending curve at normal time stored in the storage unit 85a (step -15). If it is within the range, the nth solenoid valve 55a , 55b to 58 are closed (step -16). If it is not within the range in Step-15, it is determined whether the created downward curve has a more gradual change in water pressure than the normal downward curve (Step-17). For example, the secondary side that is the downstream side of the n-th solenoid valves 55a, 55b to 58 of the spray device 5 '(from each solenoid valve 55a, 55b to 58 of each branch pipe 41a, 41b to 44 to each arch 20a, 20b to 23), the lamps 78a to 82a corresponding to the nth secondary side of the spray device 5 'are turned on, and the buzzer 37 is turned on. 'Is sounded (step -19). In Step-17, if the water pressure drop curve in the created main pipe 52 changes more rapidly than the normal drop curve, the nth solenoid valves 55a, 55b to 58 of the spray device 5 '. Is determined that there is an abnormality due to leakage of the liquid agent or the like (step -20), and the lamps 78b to 82b corresponding to the nth solenoid valves 55a and 55b to 58 of the spray device 5 'are turned on. Then, the buzzer 37 'is sounded (step -21).

  When Step-19 and Step-21 are completed, the routine proceeds to Step-16, where the nth solenoid valves 55a, 55b-58 are closed. Next, the value of n is compared with the number N of solenoid valves 55a, 55b-58 for each branch pipe 41a, 41b-44 (N = 5 in this embodiment) (step -22), and (n = N If all the solenoid valves 55a, 55b to 58 have been inspected, the inspection of the spray device 5 'is ended. In Step-22, if (n = N) is not satisfied, the pump 53 is driven (Step-23), and the water pressure in the main pipe 52 measured by the water pressure gauge 54 'is recovered (Step-24). The process of adding 1 to the value of n (n = n + 1) is performed (step -25), and the process proceeds to step -11.

  When the lamps 45, 78a to 82a, 78b to 82b of the abnormality notification panel 35 ′ are turned on, the buzzer 37 ′ is sounded, and the abnormality of the spray device 5 ′ is notified to the outside, the operation of handling the car wash machine An operator confirms the lamps 45, 78a to 82a, 78b to 82b of the abnormality notification panel 35 ', operates the notification reset button 36' to turn off the lamps 45, 78a to 82a, 78b to 82b, and the buzzer 37. After stopping ', the countermeasure (maintenance) for the spray device 5' is performed.

  As described above, the pump 53 is driven in a state in which the solenoid valves 55a, 55b-58 of the branch pipes 41a, 41b-44 are all closed in order of the arches 20a, 20b-23, and the pressure is measured by the water pressure gauge 54 '.

After the solenoid valves 55a, 55b to 58 are opened, the pump 53 is stopped, and the change in the water pressure measured by the water pressure gauge 54 '(falling waveform) and the change in the water pressure learned in advance at the normal time (falling waveform) If there is a difference greater than the measurement error, an abnormality on the secondary side of the spray device 5 ′ is determined and notified to the outside.

  When the operation device 30 is operated and the vehicle 2 to be washed is confirmed while the spray device 5 'is being inspected, the inspection of the spray device 5' is immediately interrupted, and the car washer main body 1 is moved to the vehicle 2 It shifts to the standby state in which the car can be washed.

  As described above, according to the second embodiment, the pump 53 is driven in a state where the solenoid valves 55a and 55b to 58 of the branch pipes 41a and 41b to 44 are all closed in order of the arches 20a and 20b to 23, respectively. When the water pressure measured by the water pressure gauge 54 'becomes higher than a preset value (water pressure value measured when the main pipe 52 is filled with cleaning water), the solenoid valves 55a, 41b to 44b of the branch pipes 41a, 41b to 44 are used. The pump 53 is stopped after 55b to 58 are opened, and the change in the water pressure measured by the water pressure gauge 54 'is compared with the change in the water pressure learned in advance at the normal time. If it is more gradual than the pre-learned change in water pressure, the valve is open due to clogging or the like occurring between the open solenoid valves 55a, 55b-58 and the arches 20a, 20b-23. Specified by solenoid valves 55a, 55b-58 It is possible to determine that there is a small amount of liquid agent or the like sprayed from the tanks 20a and 20b to 23, or that there is an abnormality that the liquid agent or the like is not sprayed from the arches 20a and 20b to 23. The fear of being implemented can be avoided. If the change in the water pressure of the arches 20a, 20b-23 specified from the solenoid valves 55a, 55b-58 in the open state is more sudden than the change in the water pressure learned in advance in the normal state, the open state It is possible to determine that there is an abnormality that causes leakage of the liquid agent due to damage or the like occurring between the solenoid valves 55a, 55b to 58 and the arches 20a, 20b to 23, and the vehicle cannot spray the liquid agent, etc. The fear that the second car wash is performed can be avoided.

  Further, according to the second embodiment, when it is determined that there is an abnormality on the secondary side between the solenoid valves 55a, 55b to 58 and the arches 20a, 20b to 23, the arch 20a having an abnormality in the abnormality notification panel 35 '. , 20b-23 lamps 78a-82a, 82a-82b are turned on, and the buzzer 37 'is sounded to notify the outside, whereby each arch 20a, 20b-23 can be alert | reported and a quick response can be implemented with respect to abnormality of the spray apparatus 5. FIG.

  Further, according to the second embodiment, the pump 53 is driven with all the solenoid valves 55a, 55b-58 of the branch pipes 41a, 41b-44 closed, and the main pipe 52 measured by the water pressure gauge 54 'is used. An ascending curve is created based on the water pressure, and the solenoid valve 55a, 55b of the tank 40, the main pipe 52, the pump 53, and the branch pipes 41a, 41b to 44 is compared by comparing the ascending curve with the created ascending curve under normal conditions. It is possible to detect that an abnormality has occurred in the upstream side provided with .about.58 and the solenoid valves 55a, 55b.about.58.

To 23, the spray device 5, 5 'is provided with a single arch for spraying the washing water or liquid used for washing the vehicle 2, and the arch and the main pipe 52 May be connected via a branch pipe in which a solenoid valve is interposed.

  According to the above configuration, in Embodiment 1, the pump 53 is driven with the solenoid valve of the branch pipe closed, and when the water pressure switch 54 is turned on, the pump 53 is stopped and the solenoid of the branch pipe is turned on. If the valve is opened and the water pressure switch 54 continues to be detected by the water pressure switch 54 within the above time and the water pressure switch 54 does not turn off, the solenoid valve from the opened state to the arch By determining that there is an abnormality, it is possible to detect an abnormal state in which cleaning water or liquid cannot be sprayed from the arch to the vehicle 2 due to clogging or the like generated between the solenoid valve and the arch, It is possible to avoid the possibility that the vehicle 2 is washed without spraying the liquid agent or the like.

  Further, according to the above configuration, in the second embodiment, the pump 53 is driven in a state where the solenoid valve of the branch pipe is closed, and the change (rising waveform) of the water pressure measured by the water pressure gauge 54 ′ is normal. Changes in water pressure (ascending waveform) are compared, the solenoid valve of the branch pipe is opened, the pump 53 is stopped, the change in water pressure measured by the water pressure gauge 54 'and the water pressure learned in advance under normal conditions If the change in the water pressure measured by the water pressure gauge 54 'is more gradual than the change in the water pressure learned in advance at the normal time, the clogging generated between the solenoid valve and the arch, etc. Therefore, it can be determined that the amount of the liquid sprayed from the arch is small or that there is an abnormality that the liquid spray is not sprayed from the arch, and the vehicle 2 may be washed without spraying the liquid or the like. This can be avoided. If the change in the water pressure measured by the water pressure gauge 54 'is more sudden than the change in the water pressure learned in advance in the normal state, leakage of liquid or the like may occur due to damage from the basolenoid valve to the arch. Therefore, it is possible to determine that there is an abnormality in which the vehicle 2 is not sprayed, and it is possible to avoid the possibility that the vehicle 2 is washed without spraying the liquid agent or the like.
