are supplied through the power supply circuit 11 (-5 (V) respectively at I).
, -10 (V), -30 (V) constant DC voltage, 2.5 (■) AC voltage for fluorescent display tube,
A time base signal (TB times signal) for time counting is generated.

At the same time, the light emitting diode (15C) lights up to indicate that the power has been turned on. ,
First, check the 5QHz and 60Hz selector switch (97). If the Meitchika 1 opens b1 and b'1, for 5QHK,
50H if closed! It is for use.

Assume that it is now for 6QEK. Next (: Check the status of the steam-hot water selector switch (9B). If it is open, it is for steam, and steam is used to heat the washing water (
;Become. Now for steam (suppose it is 2).

These status signals are stored in the microcomputer aυ through the input controller 11 (input controller 71) and at a corresponding location in the RAM (70).

In addition, the microcomputer (11) includes a keyboard switch (6), various switch handles, and a temperature measurement circuit c111.
The information on the power and the others is stored in the corresponding location (2) of the RAM (70).
3 (; Among the three standard washing courses that are stored in advance, the first standard washing course yRAM (70) C; 82m) and light emitting diodes (76) to (81) indicating the washing to dehydration process.

The contents of the standard washing course are as shown in Table 181.

To change the first standard washing course to another standard washing course, press the keyboard switch [7 key and number key 1]. This will be explained in the flowchart of FIG.
If not, it is determined whether the number is 2 or not.

If it is the number 2, the content of the first standard washing course stored in the RAM (70) (2) is replaced. In this case, the number key 1 is 1° 2.6
is valid; pressing other numbers will be ignored.

The keyboard switch (6) is also used when washing other than the three standard washing courses. For example, RAM (70
) when the first standard washing course is stored (= !-
[1-1! ] Press to set the washing time every 15 minutes. At that time, the time display section (151L) of the fluorescent display tube (=
The number 15 will be displayed. This can be done freely between 0 and 99 minutes (two sets are possible).

Note that this number changes every minute after pressing the start key (start button) and displays the remaining time.

When you press the rinse key, the state in which there is no rinse process σ (turns over and the light emitting diodes (77) (78) (7

~3 are added, and the light emitting diode (7) is added accordingly.
7) to (79) are lit again.

The dehydration time can be changed in the same way as the washing time by using a large 1E spittoon.

You can also change the water temperature freely (: You can change it. For example, if you press Kuzume-En-times, the water temperature during washing and the first rinse will be 40℃.
(= Changed. The water temperature is displayed by the last two digits of the fluorescent display tube (15). This temperature can also be set in one (2) settings within the range of 0 to 99°C.

By operating the function key (B) and number keys (A) in this way (2 or the special washing key (
Is it possible to change the contents of the transferred standard washing cycle by operating %RAM (70) (c)?
If you directly operate the start key without operating any of these keys, the machine will run using the GL111 standard washing cycle.

The first standard washing course will be explained below according to the flowchart. When you operate the start key elffiV, the detergent valve (
65) opens, the detergent is poured into the washing drum (2), and the cold water valve (67) opens to supply water. At the same time, the torque motor (69) rotates, and the clutch operates, causing the washing motor G (1
The rotatable force of 8 is transmitted to the drum (-, and the drum runs in reverse. When the low water level switch (99) is activated, the cold water valve (6)
7) closes. At the same time, the fluorescent display tube t1 displays the washing time "25" minutes □ and the water temperature. The water temperature is determined by converting the resistance change of a thermistor (100) installed in the washing drum into a digital quantity using a temperature measuring circuit 121), and sending it to the input port (from Bl to microcomputer a1).
The temperature is stored in the RAM (70) (2) and compared with the set temperature, or displayed on the water temperature display section (151') of the fluorescent display tube. When the low water level match (99) is closed and the water supply is stopped, Heating starts, but if the low water level switch remains open for 10 minutes, the water temperature display section (1511) of the fluorescent display tube
:, 'R6-' is displayed and the buzzer sounds at the same time. 'E
As shown in the second title, the meaning of 6- indicates that the low water level switch (99) or high water level switch (1oe) does not operate even after 10 minutes have passed after starting water supply. indicates a failure of this switch or a failure of the water supply system or drainage pulp.

When the water supply is completed, the steam valve (63) is opened and heating begins. At the same time, the water temperature (Te) is measured every 1 second and heating continues until the set value (T!') is reached.In the case of standard washing course 1, this set value ('I's) is 6
It is 0°C.

When the water temperature reaches 60°C, the steam valve (63) is closed and the washing process begins. During washing, the motor (2) repeats a strong reversal of rotating clockwise for 12 seconds, stopping for 2 seconds, and rotating counterclockwise for 12 seconds. At this time, the water level is also being measured, and when the water level falls below the specified level and the low water level switch (99) opens, C2 will display the fluorescent display tube (151).
When "E5" is displayed, the buzzer sounds at the same time. =R5° is displayed, which means that the drain valve (68) is malfunctioning.The water temperature is also measured every second (= If the temperature exceeds 100°C and continues for 5 seconds, the fluorescent display tube a!9 (2) will display “El” and at the same time the nibzer will sound. The display of “El” means that the steam valve (66) is malfunctioning. The measured temperature (Ta) is the set temperature (TIL).
When the temperature drops by 4°C or more, the steam valve (63) is closed again to perform heating.

If the measured temperature (Ta) remains 10°C higher than the set temperature (Tl) for 5 seconds, the fluorescent display tube t19 will display "B2".When the measured temperature <r:e> exceeds the set temperature (Ta) When this occurs, the steam valve (6S) is closed to stop heating.While performing this operation, the microcomputer aD counts the 50'Hz or 60H2 power frequency from the shaping circuit ■, and also performs timekeeping operations. In other words, the time display section (15B) of the fluorescent display tube displays the remaining washing time every 1 minute from the installation time (by counting). 150) Blinks at a cycle of Y1 seconds.

When the remaining time is 01, that is, the washing setting time QO has passed,
After the drainage process, the process moves to intermediate dehydration.

First, the drain valve (68) opens to drain water, and the drain time is Q1.
When , the washing motor (to) switches to the electromagnetic contactor Ms −
3C31 (:), the two poles C are switched and the balance process begins. The balance time Q2 can be freely set using the volume (101) C of the timer circuit 123. The timer circuit is controlled by the microcomputer aυ. The output from the output port (6) causes the transistor (1
02) turns off, the clock starts operating, and the capacitor (
104) (:, the stored charge is transferred to the resistance (IC1)
The capacitor voltage is then measured by a comparator (10
5) (Compared with the voltage of the second volume (101),
When the voltage of the volume is higher C; output 'I'I
goes from low to high, and this is measured by entering the microcomputer aυ(:input(-) from Bl through the game) (106).

After the balance time Q2 has passed, medium-speed dehydration begins. Medium-speed dehydration is
The torque motor (69) is off and the magnetic contactor M8-4
By operating 4'4, the dewatering motor decoy is operated with four poles. At this time, the vibration switch (turns on), so repeat the balance operation and fix it. When the medium speed time Q5, for example, 2 minutes has passed, check to see if there is a T-sugi 1. Go to. Since the standard course 1 has a 1-way mesh, the cold water valve (67)
opens, water is supplied, and the torque motor (69) and washing motor (to) operate at the same time.Then, the low water level switch ('99
) operates, the cold water valve (67) closes and the steam valve (63
) opens and heating begins. Water temperature Ts is set value TIL
When this temperature is reached, heating is stopped and T-cutting is performed.

During the rinsing process, water temperature measurement and timing operation force ζ are also carried out.
It is exactly the same as the operation in C; during the washing process.

After the rinsing time Q4, for example, 6 minutes, the water is drained, and the process moves from balance to medium-speed dehydration to step 1-2, step ζ2. Check the operation of the high water level switch (108) during the 20th rinse cycle. As a result, water is supplied to a higher water level than during washing and T-rinsing 1. There is no heating operation in the case 2. Rinse 2 → Drain → Balance → Drain without going through the process of medium-speed dehydration
Move on to 5. At T-sugi 3, the water level is still supplied to a high water level.

Similarly, CL and Techosugi 3 are not heated. After rinsing 3, the process goes through draining → balance → medium-speed dehydration and then the gluing process (move to step 2).

In the gluing process, water is first supplied to a low water level by the cold water valve (67). Here, the buzzer Qη sounds for a predetermined period of time.

One buzzer time is, for example, 10 seconds. After that, the valve (64) is opened for gluing, and the gluing is carried out in the washing drum (two people gluing is performed. Time Q5 for gluing is 5 minutes. After gluing is finished, drain → balance → medium-speed spin-drying. After that, the machine moves to the final high-speed spin-drying process.Medium-speed spin-drying (when the double-vibration switch (107) is activated, the balance operation returns to 62 again to evenly distribute the laundry. After that, it returns to medium-speed spin-drying, but When the vibration switch is activated again, the balance operation (: returns) is activated. When the vibration switch (107) is activated 10 times, the fluorescent surface water pipe fi
Pull: “E3・” is displayed and the buzzer Qη sounds.

High-speed spin problem: When moving (-, check whether the program is set to high-speed spin. In the case of standard laundry booths 1 and 3, C: High-speed spin is included in the program, but standard wash course 2 In this case, the final dehydration is also carried out at medium speed.

Vibration is also detected during the final dehydration, and when vibration is detected 10 times, the same display as above is displayed, but when no vibration is detected, the operation is continued for a time q6. Final dehydration or high-speed dehydration (when it is 2, the dehydration motor 149 is in two-pole operation C:. This is done by operating the electromagnetic contactor MS-5 (54) C:. After the high-speed dehydration is completed, the buzzer is activated. A sound will sound to notify the end. After the end, if you press the start key again, you can restart the operation under the same conditions as previously set. In other words, the memory in the RAM (70) will not be erased.

Also, when setting, if you press the weak wash key among the special wash keys (c), the light emitting diode CB25) lights up and the washing starts.
For stitching 1, 2, 3 and gluing, the reversal time of the washing motor (to) during the process is a cycle of 6 seconds of clockwise rotation → 7 seconds of rest → 3 seconds of counterclockwise rotation. Furthermore, when the dehydration key is pressed, the light emitting diode (84) lights up, and the final high-speed dehydration becomes medium-speed dehydration and is operated for the set time. Also, during heating, if the water temperature T8 becomes 10℃ or more higher than the set temperature T&, an alarm will be issued, but if the set temperature is 40℃ or less (2) Even if the water temperature T8 becomes 10℃ or more higher than this, a warning will be issued. Since there is no alarm, it is possible to prevent the alarm from being issued.

Change (2 steam-hot water selector switch (98)"4' hot water side (
In the case of steam, instead of heating after water supply, as shown in Fig. For example, if the hot water valve (66) is left open and the water temperature is higher than the set value, the cold water valve (67) is opened to reach the set temperature.

The same goes for rinsing (; controlled.

The above is fully automatic operation (I have explained it in two ways, but it is also possible to stop the operation at the end of each process.

For example, if you operate the drum key), then operate the number key 1 (), and then the start key (g), the washing will only be done for the time set by the number key (2). Also, the spin key (
After operating the number keys ((1) and the start key (G1), dehydration will only be performed for the time set by the number keys. In this case, balance → medium speed spin →
The process of switching to high-speed dehydration and successively increasing the speed (nu) is the same as in automatic driving.

As described above, in the present invention, a plurality of the most frequently used standard washing courses are stored in advance, and the desired standard washing course is read out using the numeric key (=), so that only one standard washing course can be used. It is easier to use than when creating other standard washing cycles by repeatedly operating the fun key or number keys.Also, even if you accidentally operate the start key, the 5 Therefore, the present invention is extremely practical and has no risk of wasting time. It can provide automatic washing machines.
