Description

Description: FIELD OF THE INVENTION The present invention relates to a spray car wash machine for cleaning an automobile by injecting a liquid from a spray nozzle.

[Prior Art] As is well known, spray car wash machines use water or detergent, for example, under pressure.
High-pressure spraying at 65 kg / cm ² physically removes dirt from the car body, and then chemicals such as descaling agents and wax are also low-pressure sprayed to remove dirt and polish. Such a spray car wash machine is disclosed, for example, in Japanese Utility Model Publication No. 58-138185.

Such a spray car wash machine is of the so-called unmanned stand type, and users carry out various car wash courses according to their preference by self-service, so it is relatively more careful than a gate-type car wash machine with a fixed car wash course. You can do the work. By inserting coins (including bills, prepaid cards, etc.), washing with water, shampoo, descaling,
Car wash work can be done for a fixed time for each course with wax.

[Problems to be Solved by the Invention] However, in such a conventional spray car wash,
Since the time for each process is set for each course, the user sets the course according to the time when the work is finished before a certain time or when it becomes beautiful. However, there is a drawback that wasteful cleaning work is performed.

Therefore, according to the present invention, the user can arbitrarily set the process time of each course of washing with water, shampoo, descaling, and wax, and can receive the car washing fee according to the course and time of the car washing work. It was made for the purpose of providing a spray car wash machine.

[Means for Solving the Problems] Therefore, according to the present invention, there is provided a spray car wash machine having the following configuration.

A high-pressure liquid injection system in which a water tank and a shampoo tank are respectively connected to a high-pressure pump via an on-off valve, and a high-pressure nozzle is provided at the tip of a high-pressure hose connected to the discharge side of the high-pressure pump; a descaling tank and a wax tank Is connected to a low-pressure pump via an on-off valve, a water tank is connected to a low-pressure pump different from the low-pressure pump, and a low-pressure nozzle is provided at the tip of a low-pressure hose connected to the discharge side of both low-pressure pumps. Liquid injection system, push buttons for selecting each car wash process of water, shampoo, descaling, wax, stop button to stop each car wash process, end button to end the whole car wash process, input port to introduce money to the discrimination machine An operation unit on the front of the casing provided with a return port for discharging coins from a change machine and an indicator for displaying the current amount of money, and a control device connected to each of the above devices The control device outputs an operation enable signal to the control means provided for each car wash liquid when the amount signal is input from the identification machine, and the calculation provided for each car wash liquid from the amount input from the identification machine. The amount of money input from the means is subtracted, the amount of money is displayed on the display, and when the amount of money becomes zero, the operation enable signal to the control means provided for each car wash liquid is stopped, and the pressing signal from the end button is sent. Upon receipt of the discharge signal of the amount of money when received, the storing and calculating means, the push signal from the push button for selecting each car wash process and the operation enable signal from the storing and calculating means, open the on-off valve and open the pump. Driving, outputting a driving signal to the computing means, receiving a signal from the stop button to close the on-off valve and stopping the pump, and controlling means provided for each car wash liquid, and driving signal from the controlling means to drive Calculate the amount of money according to time And spray car wash, characterized in that it comprises an arithmetic unit which is provided for each wash liquid for outputting a gold value in the storage computing means.

[Operation] Therefore, the user inserts money into the slot, presses the select button to select the required course of each of the washing, shampoo, descaling, and waxing courses, and the stop button for each course for the required time. When the car wash is completed and the car wash is completed, the end button is pressed, and the control device outputs the value subtracted from the amount put in according to the car wash time by the car wash course such as water washing and waxing as change. Therefore, at that point, the change will be returned from the return port. Further, when the car wash time corresponding to the amount of money to be inserted has passed, the control device stops the operation at that time, so that the user may insert money again.

In this way, you can select a car wash course according to your preference and pay the amount according to the car wash time.
Even if a large amount of money is thrown in, the change will be settled, so that the user can feel free to carry out the car washing work as desired.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a spray car wash machine embodying the present invention, in which a casing 1 contains the parts described below with reference to FIG. 2, and one side of which is connected to one end of a high pressure hose 2 which is connected to the high pressure hose. A high pressure nozzle 3 is connected to the other end of 2. Similarly, one end of the low pressure hose 4 is connected to the other side surface of the casing 1, and the low pressure nozzle 5 is connected to the other end of the low pressure hose 4. An indicator 6 for the amount of money to be inserted is provided on the surface thereof, and the indicator 6 is adapted to be subtracted from moment to moment during the car washing work in a manner described later.
In the illustrated example, the coin slot 7 is provided,
It is self-evident that a bill slot or a prepaid card slot can be provided. To further set the car wash course,
Push button 8a for washing, push button 8 for detergents such as jumps
b, a push button 8c for descaling and a push button 8d for wax are provided, and a stop button 9 that is pushed when one work is finished and an end button 10 that is pushed when car washing is finished. The amount of money displayed on the display 6 at the end of the car wash operation is returned from the coin return port 11. Further, when the display on the display 6 becomes zero, the alarm 12 notifies the user of that fact.

FIG. 2 is an explanatory view showing the relationship of the parts in the casing 1 shown in FIG. 1, in which a water tank 15, a shamp tank 16, a descaling tank 17 and a wax tank 18 are housed. The line L1 from the water tank 15 is connected to the high pressure pump P1 via the opening / closing valve EV1 and is also connected to the high pressure nozzle 3. The line L2 of the shamp tank 16 is connected to the high pressure pump P1 via the on-off valve EV2. Another lie L3 from the water tank 15 is connected to a lie L4 connected to the low pressure nozzle 5 via a low pressure pump P2. The line L5 from the descaling tank 17 is an on-off valve EV
3 is connected to another low-pressure pump P3, and the line L6 from the wax tank 18 is also connected to the low-pressure pump P3 via the opening / closing valve EV4. The discharge side of the low-pressure pump P3 is connected to the line L4.

FIG. 3 is a block diagram of a control device implemented in the present invention. If you insert coins, bills or prepaid cards,
The discriminator 20 outputs the amount of money to the storage / calculation unit 21, and the storage / calculation unit 21 stores the amount of money and displays it on the display 6, and at the same time, the water control unit 22a, the shamp control unit 22b, the descaling control unit 22c and the wax. The control unit 22d outputs a ready signal. Then, for example, when the water button 8a is pressed, the water control means 22a opens the on-off valve EV1 and operates the pump P1, so that high pressure water is jetted from the high pressure nozzle 3. Further, the signal from the water control means 22a is input to the calculation means 23a. A time signal t from a storage means 24a storing a unit price ma per hour and a clock 25 is input to the arithmetic means 23a, and ma * t is calculated. The storage calculation means 21 subtracts the signal from the calculation means 23a from the stored value and displays the subtracted amount on the display 6. This storage operation means 21 outputs an actuation signal to each control means 22a, 22b, 22c, 22d unless the stored value is zero. Therefore, when a predetermined amount of money is used, the storage operation means 21 causes the control means 22a, 22b, 22c, 22d to operate.
Since the ready signal that is being output to is stopped, the valve EV1 is closed, the pump P1 is stopped, and no water is output. And alarm
12, for example, informs that "please insert the price if you continue to wash the car".

When the amount of money is displayed on the display 6 (not zero), the end button 10 is pressed when the car washing work is completed.
Then, the memory calculation means 21 is controlled by each control means 22a, 22b, 22c, 22d.
The operation enable signal to is stopped, the amount displayed on the display is output to the change dispenser 26 which is a settlement means, and the change is returned to the return port 11. If you use a prepaid card, the usage fee will be reduced.

When one car wash operation is completed and the stop button 9 is pressed, a stop signal is input to each control means 22a, 22b, 22c, 22d, and the water control means 22a closes the valve EV1 and stops the pump P1. Then, if the buttons 8a to 8d are pressed again, the work is resumed.

The shampoo work, descaling work and wax work are all the same as the washing work, but the storage means 22b, 22c, 22
The unit prices stored in d are different from mb, mc, and md, respectively, and the control of the on-off valve and pump is different according to the way shown in FIG. 2, so the description thereof is omitted.

Next, the operation will be described mainly with reference to FIGS. 4 and 5 (a) to (d).

In FIG. 4, first of all, the coin is inserted into the coin slot 7 (step S1). Then, the amount of money is displayed on the display device 6 and an operation enable signal is output to each of the control means 22a-22d (step S2).

Next, the user presses any of the buttons 8a to 8d, and the respective flows are described in FIGS. 5 (a), (b), (c) and (d). Since these respective flows are substantially the same, the case where the water button 8a is pressed will be described with reference to FIG. Press the water button 8a (step
S3a), the on-off valve EV1 opens, and the pump P1 operates (step S4a). Then, as described above, the calculation means 23a calculates ma × t = m1 (step S5a). During this time car wash work
The process is continued until the stop button 9 is pressed (step S6a). For example, if ma is 1 yen and the time t when the stop button 9 is pressed is 200 seconds, then m1 is 200 yen.

The shampoo work, descaling work, and wax work are all the same, and are shown in FIG. 5 (b), (c), and (d), respectively.
Suffixes b, c and d at each step as shown in
Is attached.

For example, when performing the waxing work after the above-mentioned water washing work is completed in 200 seconds, the user may press the wax button 8d. For example, if the unit price md is 5 yen and waxing is performed for 100 seconds, then md × t = m4 = 500 yen. If all the work is finished here, the user can click the Finish button 10
While pressing, the memory operation means 21 is M- (m1 +
m2 + m3 + m4) is calculated (step S7 in FIG. 4). In the above example, the input amount M = 1000, m1 = 200, m2 = 0, m3 = 0, m
Since 4 = 500, m = (m1 + m2 + m3 + m4) = 200 + 0
At + 0 + 500 = 700, the calculated value M-m is 300 (yen). Therefore, the stored value is not zero (step S7
NO), when you press the end button 10 (step S8),
A drive signal is output to the change machine 26 and 300 yen of change is returned 11
Will be returned to.

In the above example, assuming that waxing is performed for 160 seconds, M-m = 0 (YES in step S7).
At this time, the alarm 12 notifies that effect, and each control means
22a to 22d turn off each valve EV1-EV4, and pump
Stop P1 to P3 (step S10).

[Effect of the Invention] As described above, according to the present invention, each car wash course of water washing, detergent washing, descaling, and wax can be arbitrarily selected as required, and the operating time for each car wash course can be arbitrarily set. Since you can set it, for example, the required water washing with high pressure spray and detergent washing are not performed, and the car wash will end after a while before it becomes sufficiently clean,
On the contrary, the inconvenience of wasting money is eliminated by washing with more water and detergent than necessary. Then, the charge is subtracted according to the work time for each car wash course, the change is obtained at the end of the work, and the work is stopped when the input amount of money becomes zero.

Therefore, the user can wash the car as he or she desires and can wash the car cleanly by himself or herself by selecting an arbitrary car wash course and time without wasteful expenses for light cars or large cars.
