Abstract

PURPOSE:To enable a manually set manual program to be stored in a memory section for keeping the memory even if the power supply is shut off, by providing a control means which stores the manual program in a second memory section while commanding an informing means to inform the completion of memory when a continuous operation signal for a predetermined time or longer is received from a predetermined key. CONSTITUTION:A period of time can be altered in weak dehydration. When a 'drain' key 50 is depressed, only drain in a small process of 'drain weak dehydration' is carried out and the weak dehydration is stopped. When said key is again depressed, the weak dehydration is restored. Addresses up to P10-P14 are specified by depressing 'program' keys 50... and 'numeral' keys 49... after one running program is thus altered, and when a 'writing' key 50 is kept depressed for about 2 seconds, a new running program is transferred to and stored in a RAM 38. After the completion of the operation, a buzzer buzzes. Also, when one of P1-P14, for example P10 is slightly altered, 'writing' key 50 is depressed as it is after the alteration, so that P10 is corrected partially to be stored as it is.

) has an operating steel load of 6 kg. That is, this vibration switch (33) detects vibrations due to a lock load of 6 kg during balance rotation, and vibrations due to a small lock load of 2 kg during weak dehydration rotation. Therefore, one-strong dehydration is not permitted if there is small vibration, so it is safe even if the strength of the component parts is low, and after all, safety can be maintained and material costs can be reduced.

Next, Figure 6 shows only 5 of the 10 operating programs (courses) stored in the ROM (37+) so that they will not disappear semi-permanently. There are 7 steps up to "spin", but before each "washing" step and each rinsing step, there is a small step of "draining/slight spin" whose time is set independently of the time set for each step. be.

The time in FIG. 6 is the set time for each stroke (t), and the time is counted depending on the water level according to the operation of the start switch (51), and the time (1') is counted depending on the water level and water temperature. The cold water level is the set water level, and the temperature is the set temperature. "Strength" refers to the strength of washing and rinsing. For "Strong", the rotating drum (3) is turned left and right in a cycle of 8 seconds (rotation) - 1.5 seconds (pause), and for "Weak", the rotation drum (3) is rotated for 2 seconds (rotation) - 8 seconds. (Body stop) Reverse with cycle. In addition, "water" in terms of temperature means unheated feed water, and "weak" in the "dehydration" step means weak dehydration.

Press 0) to stop the process, press it again to restart. This operation program first starts with a "prewash" step, but the time display tube (42) and temperature display tube (42)
3) displays the actual time and water temperature of the "prewash" process, and each indicator light (44)... displays the setting status. Similar displays are made in each of the following steps. In the "pre-washing" process, the water temperature is set at 60°C and the water level is set to medium-low, so steam is added to heat the water while water is being supplied to medium-low. This steam is ejected a little later than the water supply. The water level is detected by a liquid level switch (medium/low) +29), and the temperature is detected by a temperature detection element (32), and the water supply valve (13) and steam valve (+81) are controlled to open and close based on the respective detection signals. The same applies to water level and temperature control in the process.When the water temperature drops below 12°C from the set temperature, the steam valve (I8) is automatically opened to heat the water.

When the "pre-washing" process is completed, a small process of "draining and mild dehydration" is interposed. First, a low-speed reversal of 3 seconds (left rotation) - 2 seconds (pause) - 3 seconds (right rotation) - 2 seconds (pause) - 5 seconds (counterclockwise rotation) is performed without draining water, followed by a balance rotation. (clockwise rotation) is performed, and the vibration detection is performed at this point.
・Completed by 1,000 (33). If there is a predetermined vibration (corresponding to an unbalanced load of 6 or more beaks), the robot returns to low-speed counterclockwise rotation, performs balance rotation again after 5 seconds, and detects the vibration. If the vibration is below a predetermined level, water is drained for the first time while continuing balance rotation. Incidentally, it is possible to arrange the clothes more uniformly in the rotating drum (3) by inverting the clothes while they are soaked with water. Liquid level switch (low) (40 seconds after 281 is reset, the balance rotation will shift to 30 seconds of weak dehydration rotation (left rotation). During this 30 seconds, the vibration switch (33 ) is 2-
Even if vibrations corresponding to the above steel loads are detected, they are ignored and fixed. That is, detecting vibrations during weak spin-drying is to ensure safety during the next strong spin-drying, and if the weight is 6 kg or less during weak spin-drying, there is no problem in terms of strength even if vibrations occur.

When the weak dehydration rotation (30 seconds) is completed, inert rotation is performed for 15 seconds, and low-speed reversal (removal rotation) is performed for 30 seconds in a cycle of 3 seconds (rotation) - 2 seconds (pause).

The washing motor (4) is reversed by switching the power supply, and when changing from low speed to balance, the Δ connection is changed to the large connection. This is shown in FIG. In the figure, switches (58) and switches (59) are alternately closed during low-speed reversal during washing and rinsing.

At this low speed, the connection is Δ. During my balance rotation, switch (60)... and switch (61)...
However, since this is a large connection, the number of rotations will double.

In addition, similar to the dewatering motor (5) and the washing motor (4), the eight windings can be changed using the switch group (58)'..., (601').
...(6I)''..., the old dehydration rotation (425 ρ, m) is performed for the Δ connection, and the strong dehydration rotation (8 ρ, m) for the large connection.
50r, p, m) respectively.

Therefore, in order to change the winding of the washing motor (4), switches (60)..., (611) are required to prevent short circuits.
It is necessary to open the switch (59) after it is completely opened, and this takes about 0.2 seconds.

Therefore, in the previous stage of dehydration, water is not drained to improve balance and the load is increased, so a large leakage speed occurs during the pause (0.2 seconds) when transitioning from low speed rotation to balance rotation, and the Clothes that have been loosened by the low-speed reversal may harden.

Therefore, for about 2 seconds including this 0.2 seconds, the dehydration motor (5) is driven at a rotation speed suitable for weak dehydration, and the rotating drum (
3) prevents deceleration. This operation is shown in the flowchart of FIG. Here, the counter for the "dehydration" process is first cleared, and the setting status of this process is displayed. If the counter is 0, the washing motor (4) is reversed at a low speed and this is performed for 15 seconds, and this time is determined and 50 is entered in the ON, /' OFF counter. This 0
Since the N10FF counter has 10 counters and indicates 1 second, '' indicates 5 seconds at 50 counts.

This 5 seconds is the time for balance rotation. After 50 is entered, +1 is entered into the counter. Then, since the determination result of the counter becomes 1, it is determined whether the content of the 0N10FF counter is 48 or less. That is, 0.2
Determine whether seconds have elapsed. If 0.2 seconds have not elapsed, it is determined whether the contents of the ON, /' OFF counter are 30 or less, that is, whether 2 seconds have elapsed. If the time has not elapsed, the dehydration motor (5) will rotate weakly and this will continue for 2 seconds.The above judgment and processing will be performed until 60.1 seconds (the count number of the ON10FF counter is 1) have elapsed, and if it has elapsed, the dehydration motor (5) will turn ON. , -1 is performed from the contents of the 10FF counter, and 4
Let's do one. Compare this with 0 and it is not true and the counter content remains 1.

When the content of the 0N10FF counter changes from 50 to 49, the judgment and processing are performed again, but the judgment result is 50.
There is no difference between the case of 19 and the case of ・19, so add 0.1
After a total of 0.2 seconds have elapsed, the contents of the ON and OFF counters remain -18 and the contents of the counters remain 1. Then, since it is determined that they are the same at 48, the balance rotation of the washing motor (4) starts. In addition, the dehydration motor (
5) Rotating slightly to L. ON every time this operation is repeated
/' The contents of the OFF counter are decremented by -1, and -
When the number reaches 30 after 20 (for 2 seconds), it is determined that they are the same at 30, so the dewatering motor (5) stops. Furthermore, when this operation is repeated and the content of the 0N10FF counter becomes 0 after 5 seconds, the balance rotation also stops. and,
The content of the counter is incremented by +1 and becomes 2, and the result of the determination is [Proceed to the next operation in the dehydration J process. .

If the cool-down switch (54) is set, water will be automatically supplied during the last minute of any process where the set temperature is 50°C or higher, and the water will be supplied to a level one step higher than the set water level for each process. It can be carried out. In this "pre-washing" process, water can be supplied at a medium-low temperature, so water can be supplied at a medium-high temperature.As a result, the water temperature usually drops below 50°C and the clothes are cooled, making them less prone to wrinkles. Down is an operation to prevent wrinkles by one inch.The water supply can be started as long as it is before draining, and an appropriate point other than 1 minute before the end can be adopted depending on the water supply amount, outer tank capacity, etc. The cool-down operation is shown in the flowchart of FIG.

Here, the steam valve (18) is opened and closed to prevent the set temperature from dropping below 12°C, and the washing motor (4) is rotated at low speed in reverse during the set time of the washing and rinsing processes. One minute before, the set temperature for that process will be set to 50.
Determine whether the temperature is above ℃, and if not, proceed to the next step after a set time has elapsed. If the set temperature is 50°C or higher,
The water level is 51 levels higher than the set water level. Check to see if the water level is tripping (operating). If it has not tripped, open the water supply valve (13). From 1 minute before this end, the steam valve (1
8) There is no need to open the door and heat it. If the liquid level switch is lipped before the end, the water supply valve (13) is closed, and the low water temperature and low speed reversal are performed until the end of closing, cooling the clothes.

If the trip does not occur before the end of the time, close the water supply valve (13) after the time ends.

Further, when this cool down switch (54) is set, even if the water is supplied to the water level one level higher, nothing will happen unless the crystallinity is sufficiently lowered. Second, even though water is automatically supplied during this setting, the end of the water supply can be determined depending on the actual water temperature. That is, when the temperature detection element (32) detects that the actual water temperature is 40° C. or lower, water supply is terminated. This operation is shown in the flowchart of FIG. Here, the water temperature is controlled to be the set temperature by opening and closing the steam valve (18), and the washing motor (4) is rotated at low speed. When the set time for the washing and rinsing process reaches a predetermined time, it is determined whether the set temperature for that process is 50°C or higher, and if not, the process moves to the next process after the set time has elapsed (finished). . If the temperature is 50°C or higher, it is determined whether the water temperature in the outer tank (1) is at a specified temperature (40°C in this case), and if it is higher than 40°C, the water supply valve (13) is opened to supply water. When the set time becomes shorter than the predetermined time, the temperature control by steam is stopped and the water temperature decreases during the slow reversal. In most cases, the water temperature will drop below 40°C before the end, the water supply valve (13) will be closed, and the set time will end. If the temperature is still 40°C after the end, close the water supply valve (13) after the end.

After such a small process of "draining/slightly dehydrating", a "washing" process is subsequently performed. Here, detergent is added for 40 seconds. In other words, the water supply valve (13) opens and only water flows into the outer tank (
1), and then at the same time the detergent injection valve (7) is also opened and the detergent liquid is introduced into the outer tank (1). After this, the water supply valve (
13) is closed. Water supply channel (14) and detergent input channel (9)
Since the water pressure inside is divided, the detergent solution will not be sprayed strongly from the beginning. In addition, the detergent liquid is drained into the drain (25).
They simply supply water first so that they don't escape immediately. The detergent dosing valve (7) opens for 40 seconds and closes, followed by the water supply valve (13) opening again until the set water level is reached. Steam is also blown out, so the temperature reaches the set temperature.

In this way, when adding detergent, water is simply supplied first, but the method of water supply is the same when adding auxiliary agents such as softer and glue. Also, when adding auxiliary agents, initially partial pressure water is used.

When the predetermined "washing" process is completed, "F drainage/weak dehydration" and "rinsing 1" are started. From then on, each step progresses, and in the "Rinse, 4" step, the glue injection valve (23) is opened for 20 seconds, the steam from the steam source (17) creates negative pressure in the ejector (20), and the glue is dumped into the bucket (21). ) through the hose (22) and put it in. The steam source (17) may be replaced by a pump (24). If the glue is to be added manually, the glue switch (53) is set to manual.

Then, in the "Rinse 4" process, after water is supplied for 10 seconds at the beginning of the process, a buzzer sounds and the water supply is interrupted. Here, the glue injection valve is manually opened for a predetermined period of time to charge the glue.

After closing the valve, press the "Start/'Stop" key (50) to restart the water supply, supply water up to the set water level, and proceed with the process. When this "rinsing 4" step is completed, the process moves to the "dehydration" step.

In the "Dehydration" process, you can select 'Weak dehydration' or 'Strong dehydration'. In the case of 'Weak dehydration', the operation is the same as the small process of 'Drain weak dehydration', but the rotation time for weak dehydration is ( -1-
In the operating program of this rP13, the "dehydration" step is a strong dehydration process, so in this case, action 1.
This is explained below.

Following the completion of the previous process, the rotating drum (3) rotates at low speed for 3 seconds (rotation) - 2 seconds (pause) once on each side without draining water, then rotates at low speed to the left for another 5 seconds, and then performs a balance rotation. At this point, the vibration switch (33) turns on the vibration (6k).
) is detected. If there is vibration, it returns to low-speed rotation and shifts to balance rotation again, and the vibration is detected. During this time, no water was drained. If there is no vibration or no vibration, water will start draining during balance rotation, and the liquid level switch (low) (28) will be reset;')4
After 0 seconds, weak dehydration rotation is performed for 30 seconds. In addition, when transitioning from low-speed rotation to balance rotation, the dehydration motor (5) rotates for 2 seconds when the winding is changed, as described above, and the rotating drum (
3) Prevents the rotation speed from decreasing.

The vibration switch (33) is 2k during 30 seconds of mild dehydration rotation.
Vibration corresponding to a steel load of more than g is detected. If there is no vibration, weak dehydration rotation is continued for another 10 seconds, and then the winding of the dehydration motor (5) is changed to a large wire connection.
Strong dehydration rotation is performed at r, 91m. The time for this strong dehydration rotation is a set time.

If there is vibration during Tsuru dehydration rotation, perform inert rotation (15 seconds) followed by low-speed reversal (3 seconds (rotation) - 2 seconds (body stop) cycle).
Perform 7 cycles of counterclockwise rotation (to untwist clothes), followed by 3 intermittent rotations (distributed rotation to separate clothes) at a low speed of 0.5 seconds (counterclockwise rotation) to 1 second (pause). ,
Cycle, then shift to a balance rotation with a low-speed left rotation for 3 seconds. In this way, in a state where water has already been drained, in order to maintain balance, the rotating drum (3) is rotated intermittently for a short period of time, so that it does not rotate once. When transitioning to balance rotation, there is no load called water this time.

There is no need to consider torque too much. Therefore, at this time, the switch (59) is opened and the switch (61) is opened.
... is closed, and after 0.2 seconds the switch (60)...
Close. Then, when the △ connection was formed by closing the switch (59)..., the switch (61)
The state of △ connection remains transiently before it becomes a large connection due to the closure of .... Therefore, the washing motor (4) performs rotation with low torque and large slip, but at a higher rotation speed than low speed rotation, and performs balanced rotation by large connection only after the switch (bO) is closed.

As a result, the 0.2 second pause in the rotating drum (3) is substantially eliminated.

After the balance rotation, a weak dehydration rotation is performed for 10 seconds, during which the vibration switch (33) detects the vibration of the permissible steel load of 2 kg, and if there is any vibration, it is immediately turned off at the end of the 7-cycle low-speed reversal (removal rotation). cycle (3 seconds counterclockwise rotation -
2 seconds pause). Then, the cycle shifts to intermittent rotation, balance rotation, and weak dehydration rotation, and if vibration is detected during the weak dehydration rotation, the process returns to the last cycle of low-speed reversal. If there is vibration, repeat this, and if it continues 5 times, it will return to the beginning of low speed reversal (7 cycles). While the vibrations are being detected in this way, if the vibrations disappear, the weak dehydration rotation is performed for a complete 10 seconds, and then the strong dehydration rotation is performed.

In any case, once the set time has passed after switching to strong dehydration rotation, the transition will be inert rotation for 15 seconds - weak dehydration rotation for 3 seconds - inert rotation for 15 seconds, and a low speed of 3 seconds (rotation) and 5 seconds (rest). Inversion is performed for 30 seconds (6 cycles) and the "dehydration" process is completed. If, for some reason, a vibration corresponding to the same constant load occurs during this strong dehydration rotation, the vibration switch (33) is activated and the above-mentioned 7-cycle low-speed reversal is immediately started! i1. Return to i cycle (3 seconds counterclockwise rotation - 2 seconds pause), intermittent rotation - balance rotation (5 seconds) - weak dehydration rotation (1
0 seconds), and the vibration detection is re-performed during this weak dehydration rotation9.Then, the following process is the same as described above, and the process shifts to strong dehydration rotation again.

Then, since the 'P15+ operation program has finished, the buzzer sounds.

The intermittent rotation operation in this "dehydration" process is shown in the flowchart of FIG. Here, the counter for the dehydration process is first cleared, this process is displayed, and the contents of the counter are determined. Since the initial value is 0, the washing motor (4) is rotated counterclockwise at low speed.

Stop after 0.5 seconds and add ÷1 to the counter. When the content of the counter becomes 1, 1 is added to the counter again after 1 second has passed, making it 2. Below, the content of the counter is 2 and 4.
In the case of (r) in the figure, the washing motor (4) rotates the cloth at a low speed for 0.5 seconds, and if the counter contents are 3 and 5, it stops for 1 second as shown in the figure (■). After this, although it is omitted in this flowchart 1, when the content of the counter reaches 6, the washing motor (4) is rotated at low speed for 3 seconds, and when the content of the counter reaches 7, the balance shown in the figure is achieved. A rotation is performed.

Also, the operation of ``scleral water'' and ``weak dehydration'' in the ``dehydration'' process (
The operation of intermittent rotation is explained in Fig. 11, so it will be omitted).
This is shown in the flowchart in Figure 2. Here, first, clear the counter, display the process, and change the dehydration strength.
Determine weakness. If the setting is weak, the counter contents will be 0.
It is determined that this is the case, and the driver performs a rush operation (a). When this continues for a predetermined period of time, the content of the counter is set to 1 and the process returns to the point in the figure. Next, it is determined that the content of the counter is 1, and balance rotation is performed, during which vibration is detected by the vibration switch (33). If there is a vibration corresponding to a side load of 6VJ or more, the contents of the counter are cleared and the counter is returned to the state shown in the figure, that is, the balance rotation is performed after performing the lifting operation (A) again. Then, vibration is detected, and if vibration is detected, the loosening operation and balance rotation are repeated. No drainage was carried out during this time. If there is no constant vibration, the balance rotation will continue for a predetermined period of time (until 40 seconds after the water is drained and the liquid level switch (low) is reset), and then the balance rotation will stop. is added and returns to ■ in the figure. Next, the content of the counter is 2, so the dewatering motor (5) is rotated slowly (425r, p, m) and
The small stroke of "drainage/slight dehydration" is stopped for 30 seconds, and the "dehydration" stroke is stopped after a preset time. During this time, the content of the counter is 2, so weak dehydration is performed regardless of the result of vibration detection by the vibration switch (33). After this, it coasts for 15 seconds, followed by 3 seconds (low speed) - 2 seconds (
Repeat this cycle (pause) for a total of 30 seconds, alternating left and right.

If the dewatering setting is strong, it is determined that the content of the counter is 0, and a draining operation (b) is performed.

When this is done for a predetermined period of time, the content of the counter is set to 1.
Returning to 6 in the figure, the content of the counter is determined to be 1, and balance rotation is performed, during which the vibration switch (3
3) to detect vibration. If there is a vibration corresponding to one shoulder load of 64 or more, the contents of the counter are cleared and returned to the value shown in the figure. Therefore, the operation is exactly the same as the 1-weak setting. If there is no constant vibration, drain the water and turn on the liquid level switch (low >
(The balance rotation stops 40 seconds after 28+ is reset. 1 is added to the counter contents, and
Return to Next, determine that the content of the counter is 2,
The dehydration motor (5) is rotated at low speed, and vibrations are detected by the vibration switch (33) during rotation for 30 seconds.

When a vibration corresponding to ε is detected in the steel load 2, the rotation is stopped by a little less than 1 and is allowed to rotate by inertia for 15 seconds, and the contents of the counter are cleared and returned to the state shown in the figure. If no vibration is detected, it rotates slightly for another 10 seconds, cuts off the weak rotation signal, and adds 1 to the counter.

When a certain vibration is detected and the counter is cleared, a loosening operation (c) in the draining state is executed, and after a balance rotation, the counter value becomes 2. Vibration detection is performed. Here, constant vibration (
2kg compatible) is detected, immediately clear the counter and return to the state in the diagram, this time execute loosening operation (d), and repeat the same operation below.If the counter content is 2 and vibration is not detected during weak spin rotation. , adds 1 to the contents of the counter.

In this way, the weak dehydration rotation is continued for 10 seconds, and then the strong dehydration rotation is carried out. During this strong dehydration rotation, vibrations will not be detected unless there is an accident such as damage to mechanical fixing means, etc. However, for safety reasons, the vibration switch (
33) to detect vibrations. If vibration is detected here, the operation is repeated from the peeling operation (2).

When the strong dehydration rotation is performed for the set time, 13 seconds of inertia rotation, 3 seconds of weak dehydration rotation, and 15 seconds of inertia rotation are performed.
A cycle of seconds (low-speed left rotation) - 2 seconds (pause), 3 seconds (low-speed right rotation), and a complete stop is carried out for a total of 30 seconds, and then the process is completed.

The buzzer will sound when it ends.

Here, the crawling operation (a) (b) is 3 seconds (low-speed left rotation) - 2 seconds (body standstill) - 3 seconds (low-speed right rotation) 2 seconds (pause) -
5 seconds (low speed left rotation). In addition, for the pull-out operation (c), perform 7 cycles of 3 seconds (low speed rotation) - 2 seconds (pause) alternately on the left and right, then 0.5 seconds (low speed left rotation) - 1 second ( After 3 cycles of (pause), intermittent rotation for 3 seconds (low speed left rotation) is performed.

Furthermore, the loosening operation (d) starts from the last cycle of the 7-cycle low-speed reversal of the loosening operation (c)!Ii! Furthermore, when the washing motor (4) is changed from the Δ connection to the large connection, an irregular Δ connection temporarily remains, which will be explained based on the 13th [A]. here,
To simplify the explanation, 4l-2f! The switching will be explained using a 24-slot winding.・U for 1-pole delta connection
A three-phase current flows from W to instantaneous mark according to one mark from ■, from W to instantaneous mark, and as a result, a four-pole magnetic field is generated in the winding as a rotating magnetic field 7 This is a low-speed rotation secondary When (58) is opened and switch (61) is closed, and switch (60) is still open, three-phase; , a 2 transverse σ) magnetic field is generated in the winding. However, as is clear from the drawings (when it flows from R at the → mark, it is slot No. 3 and 4, when it flows from T at the → mark, it is slot no. 19 and 20, and when it flows from S at the → mark, it is slot no. The currents cancel each other out at N011.12, and the rotating magnetic field is small.7Therefore, here the slip is large and the rotation is small, but since the power is not turned off, the rotation of the rotating drum (3) is is maintained to some extent.

After this, when the switch (601 (611) is closed,
A large two-pole connection is completed, resulting in balanced rotation.

In addition, the washing motor (4) in the example is 6f! The speed is changed by switching between 12 poles.

In Figure 6, ``rP17'' is an operation program for wool, thin materials, etc. that cannot be treated with a dry cleaner, and it omits the ``prewash'' and ``rinse 1'' steps. It has changed.

"P22r is an operating program for cleaning the rotating drum (3).

'P23J is an operation program for manually operating the detergent input valve (7), water supply valve (191, hot water valve (16), steam valve (18), and drain valve (27) by disconnecting them from microcomputer control. The user arbitrarily determines and executes various set values. Therefore, the machine is equipped with a knob for manual operation. Manual operation includes electrically operating each valve by operating the knob. In the operation program, the glue injection valve (2
3) will also have to be operated manually.

'P24J' is a 4-wheel drive operating system that independently executes only the 'F dehydration' process.

It is possible to change the settings during each stroke of the representatively shown operation 2' program and record it as a new operation program fl'. This setting change is performed in response to the "function" key (50).

For example, in 'P15', first press the 'Program' key (50).
At the same time, press the "Number" key (49) (491 to 15
, and then press the "F call" key (5o) to call RO.
"Pl5" in M+37) is called to the RAM of the first person output interface (39). Then, the LED (45) corresponding to "pre-wash" to 1st dehydration lights up, and the LED +45) corresponding to "pre-wash" lights up.
blinks, time and temperature display tube (42”r, (43)
and the indicator light (44)... will display the settings for the pre-washing process. When you press the 'Call' key (50), the LED (45) for the next process will dim and display the setting status for the next process. The tube <42+, (43) and the indicator light (44)... are lit to indicate.

“Time” is calculated for each step of the operation program called in this way.
If you press the key (50) and then the "number" key (49)..., the set time of the trip will be changed to the time (minutes) of the number you pressed. The temperature ('C) is also changed by the same operation. For the water level (cold/hot), "1-" on the "Number" key corresponds to low-, 3° corresponds to "medium-low", 5 "corresponds to medium-high", and 7 "corresponds to high, respectively. You can change it according to this.The "Auxiliary agent" key (50) and the Glue switch (53)
By pressing the "Nori" key (50) and the "Number" key, you can change the time (seconds) to the number you pressed (up to 99 seconds). The detergent injection time is changed using the "auxiliary agent" key (5o). Glue switch (53) is for manual “glue”
When the key (50) is pressed, water supply interruption for gluing is set, and when pressed again, gluing is not performed. If you press the "strong/weak" key (50) during the washing/rinsing process, it will change to "weak", and if you press it again, it will return to "strong", and if you do this during the "spin" process, you will be able to use one strong spin and one weak spin. can be changed. −
For mild dehydration, the time can be changed. When you press the "Evacuation" key (5o), the system will only drain water and not perform mild dehydration during the short steps of "drainage/weak dehydration" and press it again to return.

After making changes to one driving program in this way,
Specify the address from "l" to rP14J by pressing the "Program key (50)" and "Number J key (49)..." and keep pressing the "Write" key (50) for about 2 seconds. 38), the new driving program is transferred and stored. When this work is finished, a buzzer will sound.

If you want to immediately execute the newly created driving program, press the "Start 7/Stop" key (5o) after the buzzer sounds.

The operation program stored up to ``PIJ~r P 14 J can be changed by the same operation as described above.
If you want to change PloJ a little or by a large amount, press the "Write 1" key (5o) after making the change.
lo'' is partially corrected and stored.

Next, a case will be described in which the hot water source (15) is substituted because the steam source (17) is not available. In this case, the steam switch (52) is switched to the side without steam source. Then, if the water temperature is within ±10° C. of the set temperature for each stroke, an error signal will be issued and the stroke can be executed. On the other hand, when setting the water level, it is necessary to set both the cold water level and the hot water level in consideration of the temperature.

For example, if the hot water supply temperature of the hot water source (15) is 80°C, the hot water is supplied at a ratio of 1 part to 2 parts hot water to obtain a water temperature close to 60°C in the "prewash" process of rP15J. In this case, the setting is to call the "prewash" process of r P 15-r, and change the cold water level to 1° (low) and the hot water level to 3° (medium-low). Then, after water is supplied to a low water level, hot water is supplied from a low water level to a medium-low water level, and the temperature of the mixed water can be brought close to 60°C. When using the hot water source (15) as a substitute in this way, the mixing ratio of water and hot water is determined in consideration of the set water level and the water temperature of the four seasons.

If the cold water level and the hot water level are set to the same water level, this operation will leave the water level operated later, that is, if the cold water level - hot water level setting operation is performed, the set water level of the hot water level will remain.

In addition, water (hot water) is supplied from the side where the water level is set lower.
Then, the side with the higher water level will supply hot water (water) for the remaining water level.
This operation is shown in flowchart 1 in FIG. 14. Here, we first calculate the difference between the set values for the cold water level and the hot water level, and if the set value for the cold water level is large, we check whether the liquid level switch for the water level set as the hot water level has tripped, and then 1. If it trips, close the hot water valve (16) and check whether the water level switch is tripped at the water level set as the cold water level.)
- Supply water until it rings. If it trips, the water supply valve (1
Close 3).

If the hot water level set value is higher, the cold water level side liquid level switch is tripped five times and water is supplied first. And supply me with hot water.

Furthermore, if the hot water supply temperature of the hot water source (15) is SO'C and the set temperature is 60°C, it will be stored as an operating program unless the water level is set incorrectly and the cold water level is not set. During execution, an error is displayed on the display tubes (42), (43), etc., and the process is interrupted.

Also, since the detergent injection valve (7) is opened at the same time, the cold water level is properly set and the permissible temperature range (=10'C) is reached.
Water is supplied from the small-diameter input channel (9) until .

In this embodiment, RAM (381) is backed up by a battery power source, but the battery power source is omitted and the RA
M(38) may be replaced with EE-PROM (Electrically Erasable Programmable ROM> (electrically erasable and writable write/read memory). This EE-FROM can be used even when the power is turned off. It is possible to leave the written content, and when it is desired to change the written content, to erase the written content by electrical processing and write new content.

(g) Effects of the Invention According to the configuration of the washing machine of the present invention, a manual program that has not been set manually can be newly stored in the memory unit that retains the memory even when the power is turned off, making it easier for the user to use the washing machine. Be able to improve.

Furthermore, since the completion of memorization of the manual program is notified by a buzzer, lamp, etc., the completion of memorization can be confirmed, and memorization errors due to erroneous operations can be prevented.
