Description

Description: TECHNICAL FIELD The present invention relates to a spray car wash machine having a plurality of car wash courses for injecting a plurality of types of liquids.

[Prior Art] As is well known, a spray car wash machine is used in a gas station or the like to wash a dirty car. In such a spray car wash machine, the applicant can
We filed a patent application as Japanese Patent Application No. 61-292345 for a technology that allows a car wash course such as a water wash course, a shampoo course, a water stain removal course, and a wax course to be selected. In this application, a water wash course, for example spraying water for 5 minutes, a water spray for 2 minutes and then a shampoo for 2 minutes and finally a water spray for 2 minutes, a water spray for 2 minutes and then For example, a descaling agent is sprayed for 2 minutes, then manual work is performed, and finally water is sprayed for, for example, 2 minutes.
It is possible to select a wax course in which water is sprayed for a minute, then manual work is performed, and finally water is sprayed for, for example, 2 minutes. Selection of this course is done by the selection switch,
In addition, the fees for each course are set to be entered from the fee entry point.

However, since the time of each course is predetermined by the control device, there are cases where you want to lengthen the time or shorten the time depending on the degree of dirt on the car and the area to be sprayed. Since it is automated, there is a problem in that all operations are performed in a uniform time. Actually, in the case of a car running on a snowy road, a lot of mud adheres, so it is necessary to lengthen the washing time, and in the case of a car running on the coast, it is preferable to wash it with shampoo for a long time, In the conventional car wash machine, the time was set, and such a request could not be answered.

Therefore, for example, Japanese Utility Model Laid-Open No. 57-158560 discloses a technique capable of changing the time of a car wash process. However, such a known technique cannot calculate the car wash fee according to the extension or shortening of the car wash time, which is inconvenient for a self-service car washer having a coin selector into which the car wash fee is inserted.

[Problem to be solved] Therefore, an object of the present invention is to provide a spray car wash machine capable of handling unwashed residue and automatically calculating a car wash fee.

[Means for Solving the Problems] According to the present invention, in a spray car wash machine having a plurality of car wash courses by injecting a plurality of types of liquids, a car wash fee is input through a selection switch (6) for selecting a plurality of car wash courses. A coin selector (7), a start button (9) for instructing the start and restart of car washing, an extension button (10) for re-injecting liquid to extend the liquid injection time, and a stop button (11) for stopping the liquid injection And the coin selector (7), the selection switch (6), the start button (9), the extension button (10) and the stop button (11) are used to control the pumps (P1, P2). A control device (17) for stopping the injection of the liquid is provided, and the control device (17) receives the signals from the coin selector (7), the selection switch (6) and the start button (9) to select the selected liquid. As standard, it has a function to make a jet for a certain period of time, and an extension button. The function to re-inject the liquid after receiving a signal for a certain period of time, the function to stop the liquid injection by receiving the signal from the stop button, and the unit time for each injection liquid type from the input amount according to the injection time. If the amount of money is subtracted and the amount becomes zero, the pump (P
1, P2) has a function to stop the drive.

[Explanation of Action and Effect] Therefore, if the worker selects a certain liquid jetting work, for example, a descaling course, and determines that the washing work is not sufficient for a predetermined time, for example, 2 minutes, he / she can press the extension button. After the lapse of 2 minutes, the washing operation can be further performed. Further, for example, when the washing work can be completed completely in 1 minute and 30 seconds, the next button can be removed by pressing the end button.

Then, as described above, normally, the control device may perform a standard car wash operation, and press the extension button and the end button depending on the situation. At this time, the control device subtracts the input amount of money according to the injection time and stops when it becomes zero. Therefore, even if the time is extended or shortened from the standard course, excess or deficiency of the charge does not occur. If you think that the car washing work is insufficient, you can insert more coins.

As described above, according to the present invention, it is possible to perform a car wash work that deviates from the standard course according to the dirt, and also the car wash fee can be automatically calculated. As described above, according to the present invention, the worker can extend and end the injection of the liquid by himself / herself, so that the car washing work can be performed according to his / her preference depending on the vehicle type and the degree of dirt. Therefore, there is no need to uselessly jet the liquid or leave it unwashed.

[Preferred Embodiment] In practicing the present invention, it is preferable to provide a voice utterer to guide the car wash time. By doing so, the worker can determine when to push the extension button or the end button. To give an example, (i) When the car wash time has passed half, the guide says, "The remaining half."

(Ii) Sound the buzzer every 2 seconds until 70 seconds have passed.

(Iii) When the car wash finish time is 30 seconds, "remaining 30 seconds"
And guide.

(Iv) When the car wash finish time is 10 seconds, "remaining 10 seconds"
And guide.

(V) Buzzer sounds at 0.5 second intervals until the end.

In this way, the car can be efficiently washed.

In FIG. 3, the control device 17 controls the pumps P1 to P3 and the solenoid valves EV1 to EV5 based on signals from the selection switch 6, the coin selector 7, the start button 9, the extension button 10, the stop button 11, and the end button 12. A control signal is output to each of the display devices 8 and 14 and the voice generator 15.

Next, an example of the operation of the present invention will be described with reference to FIGS.

When extending or stopping the liquid injection time, the unit price of each liquid must be determined in advance, and the work must be completed according to the amount of money put into the coin selector 7. The standard course is shown in Fig. 4, and in Fig. 4 (a), the washing course has a water unit of 100 for 120 seconds.
Assuming that the coin is a yen, 100 yen is inserted into the coin selector 7 and the start button 9 is pressed, water is jetted from time t5 and the process ends at time t6. This time from time t5 to time t6 is T1
In seconds, the control device 17 stores the calculation formula 100− (100/120) T1 = 0 (1), and the injection is stopped when the formula (1) becomes zero. It has become. Normally, this time T1 does not have to be variable, and therefore it is set independently of the extension button 110 and the end button 12, but may be extended and ended as desired.

Next, in the case of the shampoo course, as shown in Fig. 4 (b), first insert 400 yen, press the start button 9 and then t
From 1 to time t2, water is sprayed for T2 seconds (standard 120 seconds), then start button 9 is pressed to spray shampoo for time T3 seconds from time t2 to time t4 (standard 120 seconds), and finally start button is pressed to time Water is sprayed for T4 seconds from t5 to time t6 (120 seconds as standard). If the injection of the shamp is 120 yen for 120 seconds, the formula 400- (100/120) T2- (200/120) T3- (100/120) T4 = 0 (2) is stored in the controller. When the calculation formula (2) becomes zero, the work ends.

These times T2, T3, T4 can be extended and shortened by the extension button 10 and the end button 12.

In the case of the descaling course, as shown in Fig. 4 (c), first insert 500 yen, press the start button 9, then t
Water is sprayed for T5 seconds from 1 to time t2 (120 seconds as standard), and when the start button 9 is pressed, from time t3 to time t4 T6
Water descaling agent is sprayed for a second (120 seconds as standard), then manual work is performed for, for example, about 10 minutes, and when the start button 9 is pressed again, water is sprayed for T7 seconds from time t5 to time t6 (120 as standard). Seconds). 30 sprays of descaling agent in 120 seconds
If it is set to 0 yen, the calculation formula 500− (100/120) T5− (300/120) T6− (100/120) T7 = 0 (3) is stored in the control device 17, and this calculation is performed. When the expression (3) becomes zero, the work ends. These times T5, T6, T7 can be changed by the extension button 10 and the end button 12.

Finally, in the case of the wax course, assuming that the car is all washed with water, as shown in Fig. 4 (d), first insert 500 yen and press the start button 9, time t1
From time t2 to wax for T8 seconds (standard 120
Then, when the start button 9 is pressed again, water is jetted for T9 seconds from time t5 to time t6 (standard 120 seconds). Wax injection is 400 for 120 seconds
If it is a circle, the calculation formula 500- (400/120) T8- (100/120) T9 = 0 (4) is stored in the controller 17, and the calculation formula (4) becomes zero. Sometimes the work ends. This time T8, T9 is extension button 10
And it can be changed by the end button 12.

Next, the operation mode of the present invention will be described with reference to FIGS. 5 and 6. Fig. 5 shows T2, T from t1 to t2 and t3 to t4 in Fig. 4 (b), (c) and (d).
The injection operation for 3, T5, T6, and T8 seconds is shown, and since these operations are substantially the same, T2 in FIG. 4B will be described as a representative. For others, the time, pump, solenoid valve and calculation formula may be replaced with corresponding ones.

First, when the start button 9 is pressed (step S1), the pump P1
Is activated, the solenoid valve EV1 is opened, and the timekeeping operation of time T2 is performed (step S2). As a result, water is sprayed from the high pressure nozzle 3a to wash the car. In the meantime, the controller has a standard time
It is determined whether T2 has passed (step S3). While NO in step S3, the controller 17 calculates the calculation formula (2) (step S4), and when the calculation formula (2) becomes zero,
Stop pump P1 and close solenoid valve EV1 (step S5),
The injection is over. Since T3 and T4 are zero and T2 is within 120 seconds between t1 and t2, the calculation formula (2) does not become zero. While the calculation formula (2) is not zero in step S4, the control device 17 determines whether or not the end button 12 has been pressed (step S6). If so, the pump P1 is stopped and the solenoid valve EV1 Is closed, and the timing work is stopped (step S7). Then, when the start button is pressed again (step S8), the next injection work is performed. When the end button 12 is not pressed in step S6, the control device 17 determines whether or not the stop button 11 is pressed (step S9).
The stop button 11 is pressed when the worker wants to suspend work for some reason. When the stop button 11 is pressed, the pump P1 is stopped, the solenoid valve EV1 is closed, and the timing work is stopped (step S10). The worker then performs the necessary work and presses the start button 9 again (step S1
1), drive the pump P1, open the solenoid valve EV1, and restart the timing work (step S12), and return to step S3. If the stop button 11 is not pressed in step S9, the process returns to step S3.

If 120 seconds have elapsed in step S3 (YES), the pump P1 is stopped, the solenoid valve EV1 is closed, and the timing suspicion is stopped (step S13). So extension button 10
When is pressed (step S14), the pump P1 is restarted, the solenoid valve EV1 is opened, the injection is extended for 60 seconds, and the timekeeping work is restarted (step S15). When the extension button 10 is not pressed, the start button 9 is pressed (step S16), and the next injection work is performed. Therefore, after the standard time T2 has elapsed, the worker pushes the extension button 10 or the start button 9. Continuing from step S15, the control device 17 sets the extension time 60.
It is determined whether or not the second has elapsed (step S17), when it has elapsed, the process returns to step S13, and until the time elapses, in the same manner as described in steps S4 to S12,
The work from step S4 'to step S12' is performed.

The above is the operation from time t1 to t2 in FIG.
In the case of time t3 to t4 in FIG. 4 (b), the time T2 may be read as the time T3, and the solenoid valve EV1 may be read as the solenoid valve EV2. Further, in the case of time t1 to t2 in FIG. 4 (c), the time T2 is replaced with the time T5 in the calculation formula (3).
In the work from time t3 to t4 in the figure (c), time T2 and time T3, pump P1 to pumps P2 and P3, and solenoid valve EV1 to EV3 and EV5.
The calculation formula (3) may be used instead of the above. Further, in the case of the work from time t1 to t2 in FIG. 4D, time T2 is time T8, pump P1 is pumps P2 and P3, and solenoid valve EV.
The calculation formula (4) may be used by replacing 1 with EV3 and EV4.

Next, from time t5 in Fig. 4 (a), (b), (c), and (d).
The final washing work of t6 will be described with reference to FIG. All of these are substantially the same. It is explained that the remaining time is driven with respect to the input amount and there is no extension.

First, when the start button 9 is pressed (step S25), the pump P
1, the solenoid valve EV1 is opened, and the timekeeping work is performed (step S26). As a result, water is jetted from the high pressure nozzle 3a. Then, the control device 17 adopts the calculation formula (1) to be adopted.
It is determined whether (4) has become zero (step S27),
When the calculation formula becomes zero, the pump P1 is stopped and the solenoid valve EV
1 is closed (step S28), and the injection ends.

While the calculation formula does not become zero in step S27, the control device 17 determines whether the end button 12 is pressed (step S29),
It is determined whether or not the stop button 11 is pressed (step S30),
If the end button 12 is pressed, the process returns to step S28, and the work ends. When the stop button 11 is pressed, the pump P1 is stopped, the solenoid valve EV1 is closed, the injection is temporarily stopped, and the timing work is stopped (step S31). Then, when the start button 9 is pressed again (step S32), the pump P1 is driven, the electromagnetic valve EV1 is opened, the injection is restarted, and the timing work is restarted (step S33), and the process returns to step S27. In this way, the control device 17 constantly determines whether or not the end button and the stop button have been pressed until the calculation formula becomes zero.

FIG. 7 shows a preferable mode of operation of the voice generator 15 when the present invention is carried out. It is assumed that the injection work of the liquid is started at the time ta at this time, and the liquid injection is started at the time tb 120 seconds after the standard time. It is assumed that the injection work is finished, and the voice "15 is the other half" is emitted from the voice generator 15 at time tc, which is 60 seconds after the time ta.
After that, the buzzer sounds at intervals of 2 seconds, and at time td, which is 1 minute and 30 seconds after the time ta, the sound "remaining is 30 seconds" is sounded, and then the buzzer sounds at intervals of 2 seconds and 1 minute from the time ta. After 50 seconds, at time te, the sound "10 seconds left" is announced, and then the buzzer sounds at intervals of 0.5 seconds and the time t
The work ends in b. If the extension button 10 is pressed, the time is 6
It is extended for 0 seconds, and the injection work is performed until time tf. At this time, 30 seconds before that, the sound "remaining 30 seconds is left" was issued at time tg, and then the buzzer sounded at 2 second intervals, and at time th 50 seconds after time tb "remaining 10 seconds". , A buzzer sounds at 0.5 second intervals,
The work ends at time Tf. If the end button 12 is pressed between the time ta and the time Tf, the next work is started or the work is completed, and the stop button is pressed.
Press 11 to pause.

[Effects of the Invention] As described above, the present invention has the following excellent effects.

(I) It is possible to not only stop the car according to the condition of the car wash but also extend the car wash time to sufficiently remove dirt.

(Ii) The control device subtracts the input amount according to the injection time and stops the liquid injection pump when the input amount becomes zero, but the car wash fee can be calculated automatically.

(Iii) Since the standard injection time (standard course) of the liquid is determined in advance, it is convenient for normal car washing work. It can also be extended, especially for heavily soiled vehicles. The work is easy if you push the extension button.

(Iv) The amount of money is commensurate with the car washing work, and is suitable for those having a coin selector.
