7〃Rano, Kiyoshi (Since it is operated, there is no program timer to set the time like general fully automatic washing machines, and therefore, as seen in Japanese Patent Application Laid-Open No. 56-63397, the program timer is a legitimate child. It was covered with a transparent plate so that it could not be touched by hand, and it only served as an indicator to show the process being operated.

Therefore, to test run a coin-operated washing machine, the program timer is stored; insert a special tool into the hole provided on the back of the J control box, or open the J control box). and force the program timer axis to 41. After testing the process you want to test, if you want to test whether operation starts correctly by turning on the I-in, The program timer shaft had to be rotated to return to the initial state, which was a total hassle.

If the machine forgets to return the program timer to its initial state, the machine may not operate even if the user inserts a coin, or the machine may not operate properly and may stop running midway through a series of steps.
There were times when I had trouble with the manager.

(C) Purpose of the Invention The present invention enables not only testing of a desired process but also testing of whether or not operation starts correctly by inserting a coin. Even if the user forgets to return the washing machine to its initial state after finishing the operation, normal operation can be started by inserting a coin. purpose.

(d) Structure of the Invention In order to achieve the two-in-one method, the present invention automatically runs a program consisting of a series of processes such as water supply, washing, and drainage by inserting coins of a set price = 1-in type laundry. The machine is equipped with a forced operation switch that forcibly operates different processes according to the method according to the number of operations regardless of whether the fin is inserted, and furthermore, if a coin of the set price is inserted even during Mfr forced operation, 1111 automatic operation will occur. It is designed to start driving.

(E) Example 1) The figure is a front view of a coin-operated washing machine. (1) is the machine frame, (2) is the control box, and 50 yen coins and 100 yen coins are inserted into the front plate. Fin input slots (3) (4>), four-digit display device (5) (consisting of light emitting diodes (LEDs)) for displaying remaining time and input amount, and two process display devices for displaying process progress. (6) (L
(consisting of ED) are arranged. Also, on the back of the control box, a forced operation switch (7) is arranged as shown in Figure (2). This switch (7) is pushed from the back using a jig, so that the user of the washing machine cannot easily operate it.

FIG. (3) is a Glock circuit diagram of the control section, in which a microcomputer (8) is used in the embodiment.

(9) is an AC power supply, (10) is a microcomputer (
(8) is a DC power supply circuit that obtains the DC voltage (VDD) necessary to operate the microcomputer (8), and (11) is a backup power supply for retaining data in the memory (RAM) in the microcomputer (8) when the AC power is cut off. , (12) is a charging resistor that limits the current that charges the backup source (11) from the DC power supply circuit (10) via the diode (29) when the AC power supply (9) is energized, and (13) is the standard. Voltage generation power supply (14) is a comparator circuit that compares the reference voltage and the hack voltage.When the bank up voltage becomes lower than the reference voltage, the data in the memory (RAM) cannot be retained. The diode (29) prevents the current from the bank-up power supply (11) from flowing to the DC power supply circuit (10) when the AC power supply is cut off. Reference numeral 15) is a reset signal generation circuit, which operates when the power is turned on and clears the data in the RAM.

(16) is a price setting switch, which predetermines the amount to be input.After the power is turned on, the microphone [J near J viewer (8) judges the signal from this switch (16) and stores it in the RAM as the set price. memorize it internally. (17) is a 50 yen coin detection switch that outputs a signal when a 50 yen coin is inserted from the 50 yen coin slot (3);
(18) outputs a signal t'io when a 100 yen coin is inserted from the 1-in slot (4) for 100 yen coins.

The yen coin detection switch (7) is the forced operation-on/boot (7), and (19) is the switch (16) (17).
18) (In addition to 7, there is 1 on the microcomputer (8).
Other switch groups that manually operate No. 8 are shown, such as the water level switch that detects the liquid level in the 15I8 washing tank and the top lid switch that is linked to the opening and closing of the -L lid.

(20) is the right rotation drive circuit for the motor, (21) is the left rotation drive circuit for the soil, (22) is the drain valve and (+Craftch-komado circuit), and 23 is the water supply valve drive circuit - (, When a signal is output to the output terminals (A) to (D) of the two-mic IJ computer (8), it is activated via the drive circuits (24) to (27).5), (6) are the display devices, respectively.

Next, the operation will be explained based on the flowchart in FIG. (4). After the power is turned on, the set price is first stored in the RAM. And 50 yen coin detection swing 7-(17) and 100
Every time the yen coin detection switch (18) detects the insertion of a 50 yen coin or a 0100 yen coin, 50 (yen) or 100 (yen) is added to the contents of the inserted amount memory in RA l'i. In addition, in the microcomputer - C Lareta 7 Rough Town EST'Tocount'l' TEST MOD
E, 1 together 10. Make it. If the input amount exceeds the set price, full automatic operation consisting of a series of steps will begin.

In fully automatic operation, first, a signal is output from the output terminal (D) to operate the water supply valve drive circuit (23) and perform the water supply-E process.

When the specified water level is reached and a signal is received from the water level switch (19) or the wheel, water supply is stopped and the output terminal (A) (
B) outputs signals alternately from the left and right drive circuits (2).
1) (20) is operated alternately to rotate the rotor blades left and right alternately to perform the washing process. When the wash E process is completed, a signal is output from the output terminal (C) and the drive circuit 22) is activated. It operates to open the drain valve and perform the drain process. After υto water, zuzugi-[culm is carried out in the same way as washing. When the stripping process is completed, a signal is sent from the terminals T-(A) and (C), the drain valve is opened, and the clamp is activated, causing the motor to rotate clockwise not only to the rotary blades but also to the washing/dehydration tank. Also tell
This dehydration tank is rotated clockwise at high speed to perform the dehydration process.

During such fully automatic operation, the process display device 6) flashes an LED corresponding to the process being operated. Further, the four-digit display device 5) displays the remaining operating time in two digits. This display device (in May, the number 5 when coins are being inserted) displays the amount of money inserted as shown in the figure. Here L E D (28)
Lighting indicates that the displayed content at that time is the input amount. The figure shows 2!10Pl.

In parallel with the above operations, the microcomputer always checks the operation status of the forced operation switch (7). When the forced operation switch (7) is operated once while a coin is being inserted or during fully automatic operation, the flag 'TEST' in the RAM is set to "1". Since the counter 'TEST MODE' in this lI6RAM is 10J, the operation take in the RAM is cleared and the operation is stopped if it is in full automatic operation. Then, "OOJ" is displayed on the display device (5) as shown in Figure (6).

8) If the forced operation switch (7) is operated again within 5 seconds from the start of display of "100", the flag 'TES

Set STJ to 10'' and counter 'TESTMO'
Add 1 to DEJ to make the result 1 and erase the "00" display.

In this state, if you operate the forced operation switch (7) once, the flag 'TEST' will be set to rl, and the second time counter will be activated.
'TEST MODEJ is ``1.
At the same time as the previous process is carried out, the last digit of 5) will be displayed as “0”.

The minute elapsed deviation is determined by setting the flag ``TEST'' to ro and adding 1 to the counter EST MODE, making the result 12''. Flag 'TEST, becomes roJF
(The water supply and washing process are stopped, and the "1o1" display disappears.)

If you operate the forced operation switch (7) once in the , - state, the flag 'TEST' will be set to rIJ, and at this time the counter 'TEST MODE' will be set to '2 J' (7)

In this state, if you operate the forced operation switch <7) once, the flag 'TEST' will be set to 'rl', and this Moeka'>
Since the printer's TEST MODJ is "3.," the water is dehydrated and "03" is displayed on the second digit of the display device (5). If the forced operation switch (7) is operated within 1-2 minutes of the start of this process, or if there is a lag of 2 minutes, the flag 'TEST' is set to 'oJ'.
This operation is stopped and the counter 'TESTMO' is
Add 1 to DEJ to return it to 1o.

In this way, each time you operate the forced operation switch (7L11), the operating state and stop state of a different process are alternately repeated, so if you want to perform a test run, press the forced operation switch (7L) as many times as the number corresponding to the process you want to test run. In addition, the operating state of this switch (7) will automatically stop after a predetermined period of time has passed, so if you set this time to the minimum required for the test, you can operate this switch (7). It is possible to prevent unauthorized use of money.

By the way, when I was doing a test run using the forced operation switch (7), I inserted a 50 yen or 100 yen coin and the 01
When this condition is detected by the detection switches (17) and 18), the flag 'TEST' and the counter 'TEST' are set.
Since both MUDEJ becomes "0", test operation is stopped. Therefore, if the input amount does not reach the set price, full automatic operation will be performed immediately.

This means that, for example, if you want to test the process from water supply to washing and then check whether the loin starts to move correctly when you insert the loin, you must operate the forced operation switch (7) many times each time. 7-(There is no need to return the memory to its initial state, which simplifies the operation.

Furthermore, even if the service engineer resets the memory to its initial state after the test and forgets step 1, fully automatic operation will start if the user inserts the set price of coins, so there will be no conflict between the user and the administrator. I'm confused, 24-, and I don't have a clue.

Effects of the Invention According to the present invention, a desired process can be tested simply by operating a forced operation switch, and operation can be started correctly by inserting a coin after inserting a '7. It is also possible to test whether the test is successful or not, and it is much easier to perform the test compared to the conventional method, which forcibly rotates the grogram timer shaft. Even if you forget to reset the laundry 1M to its initial state after finishing the laundry, you can insert coins of the set price and it will start operating normally, so there is no risk of trouble between the user and the manager. be.
