Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a softening agent charging device for a washing machine, which dilutes the softening agent in a rinsing operation and charges it into a washing tub.

[0002]

2. Description of the Related Art Conventionally, a washing machine has been provided in which a soft finish is automatically added to a washing tub at the end of a rinsing operation to soften laundry.

This one is equipped with a soft finish agent storage container that dilutes the soft finish agent stored in response to water supply to a washing tub at once in a diluted state by the siphon principle, and stores the soft finish agent at the start of rinsing operation. It is configured to automatically fill the container with water. In other words, since the softening agent is a concentrated liquid agent, it is difficult to add the softening agent stored in the softening agent storage container directly to the washing tub, and the softening agent remains as the undiluted solution in the laundry. If it adheres, the laundry may be discolored, so the softening agent is added to the washing tub in a diluted state.

Therefore, by storing the softening agent in the softening agent storage container prior to the start of the washing operation,
The dilution water containing the softening agent can be automatically added to the washing tub at the start of the rinse operation.

[0005]

By the way, in recent years, as the rinsing operation, a so-called dewatering rinsing operation has been provided, in which instead of the pool rinsing operation, the laundry is dehydrated while water is being supplied. In this dehydration rinsing operation, the washing water contained in the laundry can be efficiently discharged, so that the rinsing operation time can be shortened.

However, in the above-mentioned conventional example, since the softening finishing agent is put into the washing tub at the beginning of the softening finishing process, when it is adopted in the washing machine which executes the dehydration rinsing operation. It is discharged as it is, and there is a drawback that the dilution water containing the softening agent does not uniformly adhere to the laundry.

In this case, it is possible to suppress the amount of dilution water input to the washing tub by setting the opening area of the discharge port of the softening agent storage container small. However, the softening agent is discharged by the siphon principle, for example. When mixed with water, it is sufficiently diluted by mixing with water, so simply setting the opening area of the discharge port of the softening agent storage container to a small value increases the resistance, and the softening agent is sufficiently discharged. There is a risk that the soft finish agent will remain in the soft finish agent storage container and the laundry cannot be sufficiently softened.

The present invention has been made in view of the above circumstances, and an object thereof is to perform dewatering and rinsing of dilution water sufficiently containing a softening agent in a configuration in which dilution water containing a softening agent is put into a washing tub. An object of the present invention is to provide a softening agent feeding device for a washing machine that can softly finish clothes by putting it in a washing tub for a long time.

[0009]

A softening agent feeding device for a washing machine according to the present invention is provided with a softening agent storage container for discharging a softening agent stored in a diluted state according to water supply.
A softening agent water supply means for supplying water to the softening agent storage container according to a rinsing operation is provided, and a dilution water storage chamber for storing the dilution water from the softening agent storage container is provided, and a wall of the dilution water storage chamber. A discharge port for discharging the dilution water stored in the dilution water storage chamber to the washing tub at a small flow rate is provided in the section (Claim 1).

In the above structure, a detergent storage container for discharging the stored detergent according to water supply is provided, and a detergent water supply means for supplying water to the detergent storage container according to a washing operation is provided, and a wall of the dilution water storage chamber is provided. After providing a water passage forming wall portion which forms a water passage through which water supplied from the detergent water supply means passes between the wall portion and the wall portion, the outlet of the dilution water storage chamber is The detergent water supply means may be provided so as to face the water passage, and may be operated at least during the operation of the softening agent water supply means (claim 2).

Further, the height dimension of the wall portion along the water passage in the dilution water storage chamber may be set smaller than the height dimension of the other wall portions (claim 3).

Further, the height dimension of the water passage forming wall portion may be set larger than the height dimension of the wall portion along the water passage of the dilution water storage chamber (claim 4).

Further, the wall portion of the dilution water storage chamber may be provided with a projecting portion for receiving a part of the water passing through the water passage and guiding it to the dilution water storage chamber through the discharge port. ).

Further, the water supply means for the softening agent may be operated for a set time from the start of the rinsing operation (claim 6).

Further, the softening agent water supply means may be operated after a set time has elapsed since the detergent water supply means was started (claim 7).

Further, the softening agent storage container is configured to discharge the dilution water by the siphon principle, and the detergent water supply means discharges the dilution water from the softening agent storage container by the siphon principle. The operation may be performed prior to the above (Claim 8).

Further, the water supply means for the softening agent may be operated again by the time the rinsing operation is completed (claim 9).

[0018]

In the case of the softening agent feeding device of the washing machine according to the first aspect, when the rinsing operation is executed, the watering means for the softening agent supplies water to the softening agent storage container. Then, the softening agent storage container discharges the softening agent in a diluted state.

Then, the dilution water discharged from the softening agent storage container is temporarily stored in the dilution water storage chamber. Here, since a discharge port for discharging the stored dilution water is provided in the wall portion of the softening agent storage container, the dilution water stored in the dilution water storage chamber is discharged through the discharge port. It is put in the washing tub.

At this time, since the diluting water is discharged at a small flow rate from the discharge port of the softening agent storage container, the softening agent can be stably charged into the washing tub for a long time. With this, the diluted softening agent can be put into the washing tub during the rinsing operation period, so that the laundry stored in the washing tub can be prevented from being discolored by the softening agent.

In the case of the softening agent feeding device for the washing machine according to the second aspect, when the softening agent water supplying means operates, the detergent water supplying means also operates, so that water is supplied from the detergent water supplying means to the detergent storage container. To be done. At this time, the water supplied from the detergent water supply means flows through the water passage formed between the wall portion of the softening agent storage container and the water passage forming wall portion and is supplied to the washing tub.

Here, since the discharge port of the dilution water storage chamber is provided so as to face the water passage, a part of the water passing through the water passage enters the dilution water storage chamber through the discharge port. As a result, it is possible to prevent the dilution water from being discharged from the dilution water storage chamber, so that even if the amount of dilution water stored in the dilution water storage chamber is small, the dilution water is poured into the washing tub at a small flow rate for a long time. be able to.

In the case of the softening agent feeding device of the washing machine according to claim 3, for example, when the amount of water supplied to the softening agent storage container increases due to an increase in water pressure, the water level of the diluting water in the diluting water storage chamber is abnormal. It will rise and overflow.

Here, since the height dimension of the wall portion along the water passage in the dilution water storage chamber is set smaller than the height dimension of the other wall portions, the dilution water storage chamber is diluted as described above. When the water starts to overflow, the dilution water gets over the wall along the water passage and falls into the water passage. As a result, it is possible to prevent the dilution water overflowing from the dilution water storage chamber from running over other wall portions and being wastefully discharged to a place other than the washing tub.

In the case of the softening agent feeding device for the washing machine according to the fourth aspect, for example, when the water pressure rises, the water level of the diluting water in the diluting water storage chamber rises and overflows. Here, since the wall for forming the water passage is set to be larger than the height of the wall along the water passage of the dilution water storage chamber, the dilution water that overflows the wall of the dilution water storage chamber and overflows. Will surely fall into the waterway. As a result, part of the dilution water that passes through the water passage will again enter the dilution water storage chamber from the outlet, so that the dilution water that overflows from the dilution water storage chamber will be thrown into the washing tub at once. Can be prevented.

In the case of the softening agent charging device for the washing machine according to the fifth aspect, the protrusion provided on the wall of the dilution water storage chamber is
Since the water passing through the water passage is guided to the dilution water storage chamber through the outlet, the water passing through the water passage can be efficiently guided to the dilution water storage chamber. As a result, it is possible to effectively prevent the dilution water from being discharged from the dilution water storage chamber through the outlet, so that the storage capacity of the dilution water storage chamber is extremely small and at least the dilution water can be washed at a small flow rate for a long time. Can be thrown into.

In the case of the softening agent feeding device of the washing machine according to the sixth aspect, since the softening agent water supply means operates for a set time from the start of the rinsing operation, the diluting water storage chamber has a softening agent storage container. Therefore, only the set amount of dilution water is stored. Accordingly, it is possible to prevent the dilution water from overflowing from the dilution water storage chamber by adjusting the set time.

In the case of the softening agent feeding device of the washing machine according to the seventh aspect, first, since the water supply means for washing operates for the set time, water enters the dilution water storage chamber through the water passage through the outlet. Then, the softening agent water supply means operates, so that the softening agent stored in the softening agent storage container is supplied to the dilution water storage chamber in a diluted state. At this time, since water has already entered the dilution water storage chamber from the water passage, it is possible to prevent the dilution water from being poured into the washing tub through the discharge port in a short time.

In the case of the softening agent feeding device for the washing machine according to the eighth aspect, when the softening agent water supply means operates to supply water to the softening agent storage container, the diluting water is discharged all at once by the siphon principle. To be done.

In this case, since the washing water supply means operates and the water has entered the dilution water storage chamber through the water passage before the dilution water is discharged from the dilution water storage chamber, the softening agent storage container Even if the diluting water is discharged all at once due to the siphon principle, it is possible to prevent the diluting water from being discharged all at once from the dilution water storage chamber to the washing tub.

In the case of the softening agent feeding device for the washing machine according to the ninth aspect, since the watering means for the softening agent operates again until the rinsing operation is completed, it adheres to the dilution water storage chamber with the rinsing operation. The softening agent can be washed off. This can prevent the softening agent from accumulating in the dilution water storage chamber.

In this case, the end portion of the rib 53 in the dilution water storage chamber 57 is provided so as to be present at a predetermined distance from the partition member 55, and the rib 53 abuts the partition member 56 with such a structure. A discharge port 58 is formed in the.

On the other hand, a rib 53 is provided on the bottom surface of the water injection case 31.
A rib 59 as a water passage forming wall portion is formed so as to leave a predetermined gap, and a water passage 60 is formed between the rib 53 and the rib 59.

In this case, the partition member 55 that forms the dilution water storage chamber 57 projects between the rib 53 and the rib 59, that is, so as to close the water passage 60 by half, and that portion forms the projecting portion 55a. It is set. Also, the partition member 5
The height dimension of the ribs 5 and the ribs 59 is set larger than the height dimension of the ribs 53.

As shown in FIGS. 6 and 7, when the detergent / softening agent storage unit 34 is attached to the water injection case 31, the first water injection port 39 of the detergent water injection member 32 has the detergent / softening agent storage unit 34.
The second water injection port 40 is located above the powder detergent storage container 46 of the softening agent storage unit 34, and the second water injection port 40 is the insertion port 50 of the case cover 47 attached to the liquid detergent / bleaching agent storage container 44.

It is located above 0.

In the detergent / softening agent depositing device 30 constructed as described above, as shown in FIG. 4, the opening 37 in the upper cover 26 is exposed so that the front surface of the detergent / softening agent storage unit 34 is exposed. It is installed corresponding to.

FIG. 8 schematically shows the electrical structure.
In FIG. 8, the control circuit 61 includes a microcomputer and an A / D converter.
A signal indicating the operating state of each switch of the operation panel 29 is given, and a water level detection signal from the water level sensor 19 is given.

The control circuit 61 controls the motor 4, the first and second water supply valves 37a and 37b, through the drive circuit 62 according to the course set by the operation panel 29.
The drain valve 16 and the transmission mechanism switching device 8 are appropriately driven, while operating information is displayed on the display unit 63 provided on the operation panel 29 and the buzzer 64 is driven at the end of the operation.

Next, the operation of the above configuration will be described. Before starting the washing operation, the user grasps the handle 51 of the detergent / softening agent storage unit 34 and pulls it forward. Then, the powder detergent storage container 46, the liquid detergent / bleach storage container 44, and the softening agent storage container 45 provided in the detergent / softening agent storage unit 34 appear, so that a predetermined amount of the powder detergent is stored in the powder detergent storage container 46. Throw in.

At this time, when the liquid detergent is used, a predetermined amount of the liquid detergent is put in through the inlet 50 of the case cover 47 of the liquid detergent / bleaching agent storage container 44. If desired, the bleaching agent is added to the liquid detergent / bleaching agent storage container 44 and the softening agent is added to the softening agent storage container 45.

Detergent / softening agent storage unit 3
After storing 4 in the original position, a desired washing course is set by each switch of the operation panel 29, and then the start button is operated. At this time, if the washing course shown in FIG. 9 is set, the control circuit 61 first opens the first water supply valve 37a in order to execute the washing operation. Then, since water is supplied to the detergent water injection member 32 from the first water supply valve 37a, water is injected from the first and second water injection ports 39 and 40 provided in the detergent water injection member 32.

As a result, water is poured into the powder detergent storage container 46 of the detergent / softening agent storage unit 34 located below the first water inlet 39, so that the powder detergent storage container 4
The powder detergent stored in 6 is washed away by the water, and the inner lid 2
It is thrown into the dehydration tank 9 through 4 in the form of a shower.

On the other hand, since the liquid detergent / bleaching agent storage container 44 located below the second water injection port 40 is also injected with water, the bleaching agent stored in the liquid detergent / bleaching agent storage container 44 becomes water. It becomes mixed and diluted. Then, the water level of the dilution water in the liquid detergent / bleaching agent storage container 44 is the cylindrical portion 4.
When the siphon passage formed by Nos. 8 and 49 is moved up to be immersed, the diluting water containing the bleaching agent is discharged to the water injection case 31 through the siphon passage by the siphon principle. As a result, the water discharged to the water injection case 31 passes through the water injection surface portion 52 and through the inner lid 24 to remove the water from the dehydration tank 9.
Is watered in the form of a shower.

Then, as described above, the first water supply valve 37a
When the water level in the tank 9 reaches the set water level through the detergent water injection member 32 due to the opening of the water, the control circuit 61 closes the first water supply valve 37a and then drives the motor 4 in a predetermined operation pattern. By carrying out the washing process,
When the washing process is completed, the drainage valve 16 is opened to execute the drainage process.

Now, as described above, washing proceeds to 1
When it is the shower rinsing stroke for the second time, the control circuit 61
The first water supply valve 37a is opened and the dehydration tub 9 is rotated. Then, water is poured from the detergent water injection member 32 into the dehydration tank 9 through the powder detergent storage container 46 and the liquid detergent / bleaching agent storage container 44 (mainly the powder detergent storage container 46). As a result, the dehydration tub 9 rotates while the laundry stored in the dehydration tub 9 is supplied with shower water, so that water and water can be simultaneously supplied to the laundry, and thus the laundry can be washed. The dirt adhering to can be rinsed efficiently.

Then, the control circuit 61 first opens the second water supply valve 37b at the second shower rinsing stroke. Then, the water injection port 42 of the water injection member 33 for softening agent
Since the water is poured into the softening agent storage container 45 from the above, the softening agent stored in the softening agent storage container 45 is mixed with water to be diluted, and the water level of the diluted water rises in the siphon passage. Then, when the diluting water containing the softening agent rises until it soaks in the siphon passage, the diluting water passes through the siphon passage according to the siphon principle and the diluting water storage chamber 57
Is discharged all at once.

Here, after opening the second water supply valve 37b in the second shower rinsing stroke, the control circuit 61 opens the first water supply valve 37 a set time after that timing.
Open b. As a result, water is supplied to the water passage 60 from the sub water injection port 41 provided in the detergent water injection member 32.
The supplied water passes through the water passage 60. At this time, since the partition member 55 closes approximately half of the water passage 60, a part of the water that has passed through the water passage 60 hits the partition member 55 and enters the dilution water storage chamber 57 through the discharge port 58. .

In this case, when the water enters the dilution water storage chamber 57 through the outlet 58 as described above, the dilution water is supplied from the softening agent storage container 45 to the dilution water storage chamber 57 by the siphon principle. Since it is set to be performed immediately before, the dilution water stored in the dilution water storage chamber 57 is suppressed from being directly discharged through the discharge port 58. Therefore, since the diluting water stored in the diluting water storage chamber 57 is not poured into the dehydrating tank 9 at once, the diluting water stored in the diluting water storing chamber 57 is kept in the dehydrating tank 9 for a long time. It can be charged at a flow rate.

Then, the control circuit 61 opens the second water supply valve 36b again immediately before the opening time of the first water supply valve 37a ends in the shower rinsing stroke. As a result, from the second water supply valve 36b, the softening agent water injection member 3
Since water is supplied to the softening agent storage container 45 through 3,
Water is poured from the softening agent storage container 45 into the dilution water storage chamber 57. Therefore, the dilution water storage chamber 57 is automatically cleaned, and even if the softening finish agent remains in the dilution water storage chamber 57, it is possible to prevent the softening finish agent from accumulating. . At this time, the softening agent storage container 45 can also be automatically washed.

According to the above structure, the water supply case 51
A diluting water storage chamber 57 partitioned by the rib 53 and the partition member 55 is formed in the diluting water storage chamber 57, and the diluting water containing the softening agent discharged from the softening agent storage container 45 is supplied to the diluting water storage chamber 57. The dilution water stored in the storage chamber 45 is discharged through the discharge port 58, so that the dilution water for the softening agent is supplied to the washing tub at once from the softening agent storage container. It can be put into the dehydration tank 9 at a small flow rate for a long time. Therefore,
When the shower rinsing process is performed, since the dilution water containing the softening agent can be shower-poured to the laundry throughout the rinsing process, the laundry can be prevented from discoloring.

In addition, the soft finish agent was sufficiently agitated as compared with the configuration in which the discharge water of the soft finish agent storage container 45 was set to be small so that the dilution water containing the soft finish agent was supplied for a long time. Dilution water can be supplied to the dehydration tank 9.

Moreover, in this embodiment, the dilution water storage chamber 57 is
Since the water passage 60 is formed laterally from the rib 53 and the rib 59 and is provided so as to face the water passage 60 of the diluting water storage chamber 57, the water passing through the water passage 60 is discharged from the water discharge port 5.
8 enters the dilution water storage chamber 57. Therefore, even when the amount of dilution water stored in the dilution water storage chamber 57 is small, the dilution water can be introduced into the dehydration tank 9 at a small flow rate for a long time.

In this case, since the partition member 55 is provided so as to project so as to close approximately half of the water passage 60, the water passing through the water passage 60 is received by the front partition member 56 and the diluted water is efficiently stored. The room 57 can be guided.

Further, since the height dimension of the partition member 55 of the dilution water storage chamber 57 is set larger than the height dimension of the rib 53, the amount of water supplied to the dilution water storage chamber 57 becomes excessive due to the high water pressure. Even when the storage capacity of the dilution water storage chamber 57 is exceeded, the dilution water overflowing from the dilution water storage chamber 57 passes over the rib 53 and falls into the water passage 60. Therefore, since the diluted water in the diluted water storage chamber 57 does not get over the partition member 55, it is possible to prevent the diluted water from being unnecessarily discharged to a portion other than the water receiving portion 23 of the inner lid 22. .

Further, since the height dimension of the ribs 59 forming the water passage 60 is set to be larger than the height dimension of the ribs 53, the dilution water overflowing from the dilution water storage chamber 57 is dropped into the water passage 60. And a part of it is again diluted water storage chamber 53
Will be invaded and collected. Therefore, since the dilution water overflowing from the dilution water storage chamber 57 is not poured into the dehydration tank 9 at once, the dilution water containing the softening agent can be supplied to the dehydration tank 9 at a small flow rate for a long time. .

In addition, by adjusting the operations of the first and second water supply valves 37a and 37b, the dilution water containing the softening agent discharged from the softening agent storage container 45 by the siphon principle is stored in the dilution water. Prior to being supplied to the chamber 57, water is supplied to the water passage 60 to dilute the water storage chamber 5.
Since the water is made to enter the 7 through the discharge port 58, even if the water containing the softening agent is supplied to the dilution water storage chamber 57 at once by the siphon principle, the dilution water stored in the dilution water storage chamber 57 is diluted. It is possible to prevent water from being suddenly introduced into the dehydration tank 9 through the discharge port 58.

By the way, the amount of water supplied to the softening agent storage container 45 in the shower rinsing operation is set to the optimum amount so that the siphoning operation is performed only once in the softening agent storage container 45. When the amount of water supplied to the storage container 45 is too large, water may be supplied from the softening agent storage container 45 to the dilution water storage chamber 57 more than once by the siphon principle. Will overflow.

In this case, when the diluting water overflows from the diluting water storage chamber 57, the diluting water containing the softening agent is prevented from being unnecessarily charged into the dehydrating tank 9 as described above. However, it is unavoidable that the concentration of the diluting water added to the dehydration tub 9 fluctuates, and therefore the softer treatment effect on the laundry may be non-uniform.

Here, a factor that increases the amount of water supplied to the softening agent storage container 45 is the relationship between the amount of softening agent stored in the softening agent storage container 45 and the water supply flow rate. That is, the higher the water level of the softening agent stored in the softening agent storage container 45 or the higher the water supply flow rate,
This is because the siphon operation occurs in a short water supply time.

Therefore, by appropriately setting the water supply time according to the water level and the water supply flow rate of the softening agent stored in the softening agent storage container 45, the dilution water overflows from the dilution water storage chamber 57. Can be prevented.

FIG. 10 shows the relationship between the amount of the softening agent stored in the softening agent storage container, the water supply flow rate, and the water supply time. As the water supply time, the time during which the first siphon operation occurs is shown. There is. From FIG. 10, the greater the amount of the softening agent stored in the softening agent storage container 45,
Alternatively, it can be seen that it is desirable to set the water supply time shorter as the water supply flow rate increases.

In this case, as means for setting the water level and the water supply flow rate of the softening agent, a water level sensor for detecting the water level of the softening agent and a flow rate sensor for detecting the water supply rate may be provided.

Next, a modification of the present invention will be described. Figure 11
Shows a detergent / softening agent storage unit 34.
In FIG. 11, the detergent / softening agent storage unit 3
A transparent plate 65 is provided on the front surface of the liquid detergent / bleaching agent storage container 44, the powder detergent storage container 46, and the softening agent storage container 45 provided in the main body case 43 of FIG. The letters ",""medium," and "low" are projected together with the index line "-". In addition, each storage container 4
4, 46 and the inner wall of the storage section 45 are also “high”, “medium”,
The character "low" is projected together with the index line "-". These characters and index lines are integrally formed when the transparent plate 65 and the main body case 43 are resin-molded.

According to this structure, the amount of the powder detergent, the bleaching agent or the softening agent can be visually confirmed, so that an appropriate amount can be added without using a measuring cup.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. As the softening agent storage container 45, it is not necessary to discharge the dilution water using the siphon principle. Water may be supplied to the water passage 60 at least during the water supply period to the softening agent storage container 45.

The protruding portion 55a of the partition member 55 may be omitted. You may comprise so that only a soft finish may be added. Supplying water to the water passage 60 during the rinsing operation may be omitted, or the water passage 60 may be omitted.

[0089]

As is apparent from the above description, the softening agent charging device for a washing machine of the present invention has the following effects. According to the first aspect, the dilution water containing the softening agent discharged from the softening agent storage container is diluted by supplying water to the softening agent storage container by the watering agent for softening agent according to the rinsing operation. The water is stored in the water storage chamber, and the dilution water stored in the dilution water storage chamber is discharged into the washing tub at a small flow rate through the discharge port provided in the wall. It is possible to uniformly apply a soft finish to the laundry stored in.

According to the second aspect, since the water passage is formed by the water passage forming wall along the wall of the dilution water storage chamber, and the discharge passage is provided so as to face the water passage. Water can be prevented from entering the dilution water storage chamber while water is being supplied to the water passage and the discharge of dilution water through the discharge port can be suppressed, so that the amount of dilution water stored in the dilution water storage chamber is at least small for a long time. It can be put into the washing tub at a flow rate.

According to the third aspect of the present invention, the height dimension of the wall portion along the water passage in the dilution water storage chamber is set smaller than the height dimension of the other wall portions. Even if the dilution water begins to overflow, the dilution water will pass over the wall along the water passage, and the dilution water will pass over the other walls and be drained wastefully outside the washing tub. It can be prevented.

According to the fourth aspect, the height dimension of the water passage forming wall portion is set to be larger than the height dimension of the wall portion along the water passage of the dilution water storage chamber. Even if the dilution water overflows from the dilution water storage chamber, a part of the overflowing dilution water will enter the dilution water storage chamber again through the water passage, thus overflowing the dilution water storage chamber. It is possible to prevent the diluted water from being thrown into the washing tub at once.

According to the fifth aspect of the present invention, the projection provided on the wall of the dilution water storage chamber receives a part of the water passing through the water passage and guides it to the dilution water storage chamber through the discharge port. Therefore, it is possible to effectively prevent the dilution water from being discharged from the dilution water storage chamber through the outlet, so that the amount of dilution water stored in the dilution water storage chamber is extremely small and the dilution water is kept at a small flow rate for a long time. Can be put into the washing tub.

According to the sixth aspect of the present invention, since the water supply means for the softening agent is made to operate for the set time from the start of the rinsing operation, the diluting water storage chamber is provided with the set amount of the softening agent storage container. Only the diluting water is stored, so that the diluting water can be prevented from overflowing from the diluting water storage chamber by adjusting the set time.

According to the seventh aspect of the present invention, since the water supply means for the softening agent is made to operate after the set time has elapsed since the water supply means for the detergent was operated, the dilution water containing the softening agent is diluted. By the time the water is supplied to the water storage chamber, the water that has passed through the water passage has entered the dilution water storage chamber, which can prevent the dilution water from being thrown into the washing tub at once through the outlet. .

According to the eighth aspect of the present invention, the softening agent storage container is configured to discharge the diluting water by the siphon operation, and the detergent water supply means is siphoned from the softening agent storage container. Since it operates before the dilution water is discharged, the washing water supply means operates and enters the dilution water storage chamber through the water passage before the dilution water is discharged from the dilution water storage chamber. Therefore, even if the dilution water is discharged from the softening agent storage container at a stretch, it is possible to prevent the dilution water from being discharged from the dilution water storage chamber to the washing tub at once.

According to the ninth aspect of the invention, since the water supply means for the softening agent is made to operate again until the rinsing operation is completed, the softening agent adhered to the dilution water storage chamber with the rinsing operation is finished. It is possible to wash away the agent, thereby preventing the softening agent from accumulating in the dilution water storage chamber.
