CONSTITUTION:This car washing machine has a spray gun 4 fitted with a hand valve 3 intermitting a spray, and at the time of opening this hand valve 3, car washing time is subtracted, and at the time of closing, stopping time is subtracted as well, but if this stopping time exceeds the specified value, the car washing time is subtracted irrespective of opening or closing of the hand valve 3, and when the car washing time is reached to the specified value, it operates so as to finish the car washing. In addition, the progress of each time is displayed on a display part in detail, and a user is able to perform his car washing operation along with the elapse of the time displayed. Accordingly, during the specified stopping time, even if spraying is stopped, the washing time will not progress any longer, so that the user stops the spray free from care so that he can do correction work or the like, thus improvement in service is well promotable.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a car wash machine of the type that is equipped with a money handling device and performs paid car washes.

In general, this type of device has multiple car wash courses set according to the length of time the car can be washed and the different processes to be performed, such as "water washing" and "detergent washing", and the user can perform them. They pay for the car wash course, select the course, and wash their cars. The car wash operation performed in this way is performed continuously for the time specified for the car wash course, so you can temporarily stop the spray during the car wash to fix a case where you forgot to close a window, or to clean dirt or scratches on the car body. There is a drawback that you cannot freely do what you say you want to check.

In contrast, using a well-known spray gun with a hand valve,
If the handheld mass spray can be started and stopped freely, it will be very convenient in terms of the above points, but even if the handheld valve is used to stop the spray, the car wash time will elapse.
If spraying is frequently interrupted, there is a risk that the car wash course will end without being able to wash the car sufficiently.

In view of the above points, this invention uses a spray gun with a hand valve to freely start and stop spraying, and detects the opening and closing of the hand valve to detect when a car wash is being executed and when the car wash body is stopped. The purpose of the present invention is to provide a device that performs control according to each time and improves service to customers.

Hereinafter, an example of the integrated structure will be explained based on the drawings.

FIG. 1 is an explanatory diagram showing the configuration of an embodiment of the present invention. 1
1 is a spray washer body, and a hose 2 extends outward, and a spray gun 4 equipped with a hand WRwi valve 3 is attached to the end of the hose 2. The hand valve 3 is always energized in the valve closing direction, and can be pushed open by squeezing the lever provided.
It is a.

A water storage tank 5 receives water from a water source 6 via a ball tap 7 and stores water at a predetermined water level.

8 is a detergent tank for storing detergent liquid; 9 is a detergent water tank for storing detergent water obtained by diluting the detergent liquid in detergent tank 8; the detergent liquid is supplied from a solenoid valve 10 and detergent Wj8, which are opened and closed by a float switch that detects the water level in the tank; Water is supplied from a water source 6 via a pipe line 12 equipped with a mixer 11 that sucks up water. A pump 13 sucks water or detergent water from the water storage tank 5 or the detergent water tank 9 through pipes 14 and 15, and pumps it to the spray gun 4 through a suction side pipe 16. 17 and 18 are pipe line 14
- By alternately opening the electromagnetic valves provided in each of the pumps 15, the cleaning water pumped by the pump 13 is switched to water or detergent water. Reference numeral 19 denotes an unloader valve provided in the pump discharge side pipe line 16. When the hand valve 3 of the spray gun 4 is shut off while the pump 13 is operating, the water pressure in the pipe line 16 is reduced to the water pressure during normal operation (in this example, 50-70kg/ca+
When the pressure reaches a predetermined value (in this example, 80 kg/cm2), the valve opens and the cleaning water is returned to the water storage tank 5 or the detergent water tank 9 via the pipe line 20. 21 is a pressure switch provided in the pipe line 20. This is used to detect the water pressure of the cleaning water bypassed into the pipe line 20 when the unloader valve 19 is opened, and is used to detect the open/closed state of the hand valve 3 through the opening/closing of the unloader valve 19. 22 is the same. A pressure regulating valve provided in the pipe line 20 restricts the flow line 20 downstream of the pressure switch 21 to ensure the detection operation of the pressure switch 21. 23 and 24 are water tanks 5 and 1 detergent water supplied from the pipe line 20. Solenoid valves are provided in the branch pipes 25 and 26 leading to the ff19, and 23 and 24 are opened and closed simultaneously with the solenoid valve 17 and 18, respectively, so that the cleaning water returned from the pipe 20 can be used to clean various types of water. In step 9, the flow path is switched so that water and detergent water are not mixed.

Therefore, when the pump 9 is driven, water or detergent water is force-fed to the discharge side pipe line 16, and if the hand valve 3 in the spray gun 4 is closed at this time, the unloader valve 19 is opened and various types of washing water are supplied. will be returned to. Thereafter, when the hand valve 3 is opened, the unloader valve 19 is closed and the spray gun 4 starts spraying.

FIG. is equipped with a cash handling device 32 attached thereto. The control panel 30i is provided with a coin slot 33, a car wash course selection key 34, and a car wash start key 35, each of which is arranged according to the operating procedure. Coins inserted into the coin slot 33 are transferred to the money handling device 32. The money handling device then counts the inserted coins and refunds them to the return slot 36 as necessary. Car wash courses A to C are set in the car wash course selection key 34, for example: A course is a water wash course in which only the water in the stored water Ni5 is sprayed for 3 minutes; B course is a water wash course that first sprays the water in the stored water N5 for 1 minutes (hand washing), detergent water in the detergent tank 9 for 1.5 minutes (washing), water again for 1.5 minutes (rinsing)
Standard course of spraying each in sequence: CE- or water for 1.5 minutes (hand washing), detergent water for 2.5 minutes (washing),
A long course in which water is sprayed for 2 minutes (rinsing) in sequence; the fees are set according to the length of the car wash time and the content of the car wash for each course. Note that information such as the car wash process and car wash time for each course is stored in a memory 43, which will be described later.

Therefore, the user first inputs the fee corresponding to the car wash course he/she wants to execute into the course input slot 33, then specifies the desired car wash course using the car wash course selection key 34, and finally presses the car wash start key 35 to start the car wash. executed.

37 is a display section attached to the control panel 30;
The time progress of the car wash course to be executed is displayed by turning on/off the L E I) group, and the car wash execution time display section 38
and a car wash down time display section 39.

The car wash execution time display section 38 is divided into groups of LEDs for each process such as "prewash", "wash", and "rinsing".
A number of LEs corresponding to the execution time of each step of the car wash course specified by the car wash course selection key 34.
D is lit and displayed, and during car washing, the LED t- is sequentially turned off every unit time (30 seconds in this example) to indicate the passage of time. Therefore, if it is course A, at the start of the car wash,
Six LEDs for "Hand Wash" are lit, and for course B, two LEDs for "Hand Wash", three LEDs for "Wash", and three LEDs for "Rinse" are lit, and the LEDs are turned off one by one in the order in which the car wash progresses. go. The car wash stop time display section 39 displays the time during which the car wash can be temporarily stopped by turning off the hand valve 3 of the spray gun 4 during the car wash, and the stop time (A) set for each car wash course A to C is displayed. - The number of LEDs corresponding to 1 minute for the B course and 2 minutes for the C course is turned on, and during the pause, the LEDs are turned off one after another every unit time (20 seconds in this example). Therefore, while the LED of the stop time display section 39 is lit, the car wash can be stopped without the car wash time set in the car wash course elapsed.

Figure fjS3 is a block diagram showing the control system of the above embodiment. A control section 40 includes an input/output circuit 41, a CPU 42, and a memory (ROM-RAM) 43 to form a microcomputer. The input side of the input/output circuit 41 is connected to the keys of the control panel 30, the money handling device 32, and the pressure switch 21, and the output side is connected to the pump 13, the solenoid valves 17, 18, 23, 24, and the display section 37.
is connected to VC. 44 is a display drive circuit that performs display operations on the display section 37.

FIG. 4 is a flowchart showing an outline of a program executed by the control unit 40''C, and the operation of the embodiment will be explained below based on this diagram.

In the control panel 30, after inserting money, a car wash course is designated using the car wash course selection key 34, and when the car wash start key 35 is pressed, the program starts. First, the car wash course specified by the selection key 34 is read, control data corresponding to the course is read from the memory 43, and the car wash time and rest time are set on timers T1 and T2 (7), and the display unit 37 displays the respective remaining times. Display (1). Next, the pump 13 and the electromagnetic valves 17 and 23 are driven to enter a mode in which water in the water storage layer 5 is sprayed (2). Here, the user holds the spray gun 4 and opens the hand valve 3 to start the spray gun.

After the pump 13 is driven in step (2), the hand valve 3
When the pressure switch 21 detects that the valve is opened (3)
, determines that the car wash has started, counts the elapsed time after that, and subtracts the car wash time timer T1 for each unit of time elapsed, and calculates T
The elapsed time is displayed on the car wash time display section 38 in accordance with the value of 1 (4). As the timer T progresses, when it is detected that it is time to change the process (5) (if the car wash course is B-C course), the solenoid valves 17/23 to 18/24 or 18/24 open. If the valves are open, switch to 17 and 23 to open the valves 6) and change the cleaning water to be sprayed. In this way, the spray gun is advanced and the timer T1
When the value of becomes O (7), the control output is turned off, that is, the pump 13 is stopped, and each electromagnetic valve 17, 18, 23, and 24 is closed (8), and the car wash is completed.

Pressure switch 21 detects when hand valve 3 is closed during car washing.
When detected (9), it is determined that the car wash has stopped, and the timer T2 is subtracted every time a unit of time elapses, and the elapsed time is displayed on the downtime display section 39 according to the value of T2 (10). After this, if the hand valve 3 is opened again (9) step (4)
) to advance the car wash time. Also, if time passes without the hand valve 3 being opened and T2 reaches O (11), it is determined that the rest time has expired, and the car wash time T1 is determined every subsequent time elapsed.
is subtracted (12), and when T1 becomes 0, the control output is turned OFF even during the rest period (8), and the car wash ends.

Therefore, in the above embodiment, when the hand valve 3 is closed, the car wash time is subtracted 4), and when the valve is closed, the rest time is subtracted 10), and if the rest time exceeds a predetermined value, the hand valve 3
The car wash time is subtracted regardless of whether the car is opened or closed (12), and when the car wash time reaches a predetermined value (7), (13) the car wash is finished (8)
It works like that. Further, the progress of each time period is displayed one by one on the display section 37, and the user can perform the car washing work according to the progress of the displayed time period.

This invention is constructed as described above, and since it is equipped with a spray gun with a hand valve, the user of the device can freely start and stop the spray gun at hand. In addition, by detecting the opening and closing of the hand valve, the car wash execution time and car wash pause time are measured separately, and the car wash time does not proceed even if the spray is stopped during a certain pause time, so the user can feel safe. You can carefully stop the spray and perform touch-up work, allowing you to gauge the direction of service.

Furthermore, the downtime is limited to a certain range, and if the machine is stopped for a long time, the car wash time will advance and the car wash will automatically end, so there will be no disadvantage to the owner of the device.
