Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a coin-operated washing machine that automatically runs a program consisting of a series of steps such as water supply, washing, and drainage by inserting a coin.

(B) Conventional Technology Conventionally known coin-operated washing machines automatically run a predetermined program consisting of a series of processes such as water supply, washing, and draining when a set amount of coins are inserted. There is no need to set the time with a timer like in a fully automatic washing machine, so the program timer child is covered with a transparent plate so that it cannot be touched by hand, and it is used to show the operating process. It only served as an indicator.

To do a test run of the coin-operated washing machine, I opened the 10-leaf box that houses the program timer and placed 7 grams in the 10-lb box of the process in which I wanted to forcibly test the timer axis. It had to be rotated, which was a hassle.

(c) Purpose of the invention The present invention makes it possible to carry out test runs every ton, while also preventing the test runs from being used without paying. shall be.

(D) Structure of the Invention The present invention is a coin-operated washing machine that automatically rotates a block machine consisting of a series of processes such as water supply, washing, and drainage by inserting a coin. The switch is equipped with operating means for selecting a process to be forcibly operated according to the number of times the switch is opened, and forcibly operating the selected process for the shorter of the opening time of the switch or a predetermined time set in advance. be.

With this configuration, if you close the forced operation switch the number of times corresponding to the process you want to test run, that process will be forced to operate, and moreover, during this operation time, the forced operation switch / switch will not be closed. Since the forced operation switch is only operated for a short period of time between the current time and a predetermined time, even if the forced operation switch/g is kept closed for a long time, the forced operation will stop after the specified time has passed. ,Therefore, unauthorized use using the forced operation switch is prevented.

Fully automatic operation consisting of processes has started.

In fully automatic operation, first, a signal is output from the output terminal 'F(D) to operate the water supply valve drive circuit (23)5, and water is supplied. When the specified water level is reached and a signal is received from the water level switch <19), the water supply is stopped +L and the output terminal <A>CB
), the left and right drive circuits <21)
(20) is operated alternately to rotate the rotor blades alternately left and right to perform the washing process. When the loop I process is finished, the output terminal (
C) outputs a signal to operate the drive circuit (22) to open the drain valve and drain water.

After draining, a process similar to washing is carried out. When the rinsing process is finished, a signal is output from the terminals (A> and (C)), the drain valve is opened and the clutch is activated, and the clockwise rotation of the motor is transmitted to the V washing and dewatering tank if only the rotary blade is used. Allow the dehydration tank to rotate clockwise at high speed to perform dehydration.

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 the last two digits. This display device (5) displays the amount of money inserted as shown in Fig. (5) while coins are being inserted. Here L E D (28>
Lighting indicates that the displayed content at that time is the input amount. The figure shows 250 yen.

Also, the flags set in the microcomputer during fully automatic operation are ``TEST'' and ``TEST END'' (-1
At 10, the power is set to TEST MODE, +Mo'O.

Next, a case will be described in which the forced operation switch (7) is pressed and closed during fully automatic operation in order to perform a test operation.

Ru. First, when this switch is closed once, the flag 'TE
Set ST to "1" and set the flag 'TEST ENDJ:+)', -'TEST MODEJ' to 'O'.
J tt (7) Clear the operating data in II (RAM), stop fully automatic operation, and wait up to 5 seconds until the forced operation switch (7) is opened.
For a second, rooJ is displayed on the minus digit of the display device (5) as shown in Fig. (6).

When you release the forced operation switch (7) and open it, the flag 'TEST' is returned to I"0", the counter 'TEST MODEJ is incremented by 1, and the result is shifted to 1. 77 again 'TEST ENDJ 'b'0''
cZ t le.

When the forced operation switch (7) is pressed again and closed, the counter 'TEST MODEJ' is now 1, so the water supply valve drive circuit (23) is activated to perform water supply operation, and the display device (5) is activated. ) will display “01” in the last two digits. This water supply is carried out for a maximum of 1 minute while the switch (7) is closed. 1 minute passage-? If so, flag 'TE
Since STEND is set to "1", the water supply operation is stopped even if the switch (7) is kept closed.

Next, when the forced operation switch (7) is opened and closed, the flag 'TESTJ is returned to 'OJ' and the counter 'TEST MODEJ is incremented by 1, resulting in a value of 2.

Also, set the flag town ES ENDJ to "0".

When the forced operation switch (7) is pressed again to close it, the counter 'TEST MODE' is now set to 2, so the drain valve drive circuit (22) is activated to perform the -C water operation, and the display device ( 5) Display 102 in the last two digits. This drainage is also carried out for a maximum of 1 minute while the switch (7) is closed. After 1 minute, flag 'T'
Since EST ENDJ is set to rl, switch (7)
Even if the water is closed and controlled, the drainage operation will be stopped.

Next, when the forced operation switch (7) is opened, the flag 'TEST' is returned to 'O' and the counter 'TEST' is set back to 'O'.
Add 1 to MODEJ, making the result 3.

Then, when the forced operation switch (7) is closed again, the counter 'TEST MODEJ is 3, so the drive circuits (20) and (22) are activated to perform dehydration operation, and the display device (5) is activated. Display 103J in the last two digits. This dehydration operation is performed for a maximum of 2 minutes while the switch 1 (7) is closed, and after 2 minutes, the 'TEST'
END, WO' 1, LC, switch f (7) is closed to stop the dehydration operation even if it is set to M.

Next, when the forced operation switch (7) is opened, the flag 'T' is set.
Together with ESTJ and 'TES-ENDJ r6' Zuruto,
The counter ``DEST'MO[lEJ'' is also returned to 0.

By closing the forced operation switch (7) once in this way, R
The operation data in the AM is cleared, and if it is closed twice, water supply operation will be performed, and if it is closed three times, water supply operation will be performed,
If the lid is closed four times, dehydration will begin.

The above explanation was made during fully automatic operation, but even if coins are being inserted or no coins are inserted, as long as the source is turned on. This is caused by the TL #7 thrower signal generation circuit (15) during fully automatic operation.
7 Rough 'TEST'? This is because 'TEST END, + and counter' TEST MODEJ becomes O.

(F) Effects of the Invention According to the present invention, when performing a test run, the forced operation switch (7) must be closed the number of times corresponding to the process to be tested (for example, three times in the case of testing the drainage process in the embodiment). If this is the case, tests can be carried out in a simple manner compared to the conventional method in which the program timer shaft is forcibly rotated to a position corresponding to the process. The forced operation delay time is the shorter of the opening time of the forced operation switch (7) and the predetermined maximum time (for example, 1 minute for water supply in the embodiment), so this switch (7) For this reason, it is possible to provide a forced operation switch in a position where it is relatively easy to operate.
