On the other hand, the proper detergent concentration when spraying and permeating the laundry 38 is 5 to 20 times. Here, the detergent concentration is a value obtained by multiplying the detergent concentration recommended by the detergent manufacturer by one. For example, the rated washing water volume of a washer / dryer with a washing capacity of 8 kg is 6
Since it is about 8 L, when the detergent used with this washing water amount is dissolved with 3.4 L of water, the detergent concentration becomes 20 times.
If a detergent solution having a concentration of 20 times is to be produced and used at one time, a large detergent dissolution chamber 21c having a volume of at least 3.4 L is required, and it cannot be installed in the back panel box 17. Therefore, the volume of the detergent dissolving chamber 21c can be reduced by diluting the high-concentration detergent liquid dissolved with a smaller amount of water in the mixing chamber 21v by 5 to 20 times and spraying it on the laundry 38 so that the detergent is dissolved.

ることも可能である。Main water supply solenoid valve 20 and auxiliary water supply solenoid valve 22
The flow rate of water supplied from the plant varies depending on the tap water pressure. The tap water pressure of a general household where a washing machine is used is 0.03 to 0.8MP
Within the range of a, the flow rate Q2 flowing through the main water supply solenoid valve 20 is 5 to 20 L per minute, and the flow rate Q1 flowing through the auxiliary water supply solenoid valve 22.
Is 1-2 L per minute. Therefore, assuming that the concentration of the high-concentration detergent liquid flowing down from the overflow channel 21f is D0, the mixing chamber 21
The concentration D1 of the detergent liquid diluted with v and applied to the laundry is
D0 × Q1 / (Q1 + Q2) can be calculated, and tap water pressure is 0.
About 0.17D0 at 03MPa, about 0.0 at 0.8MPa
It becomes 9D0, and the lower the tap water pressure, the higher the concentration. Further, the concentration D0 increases as the amount of detergent increases. That is,
In order to obtain the above-mentioned proper detergent concentration, D0 needs to be about 118 times (= 20 / 0.17) or less. From the above, the volume of the detergent dissolving chamber 21c is 0.58 mL (= 68 L
/ 118) is required. This calculation is based on the case where the main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are continuously opened, and the auxiliary water supply solenoid valve 22 may be intermittently controlled to be opened or closed, or a solenoid valve having a smaller flow rate may be used. It is possible to further reduce the volume of the detergent dissolving chamber 21c by reducing Q1 in step 1.

い。The detergent stirring blade 50 has a disk shape convex toward the upper side, a radial blade 50a is provided on the brim portion of the upper surface, and a vertical blade 50b is provided on the cylindrical surface portion, and stirring is provided at the center of the lower surface. There is a hole into which the drive shaft 51 is fitted, and a cylindrical member 50c is provided concentrically with this hole so as to project downward. The blades 50a and 50b have a triangular prism shape. The blade shape is preferably a screw shape considering the efficiency of dissolving the detergent. However, in the screw type, since the air pocket above the shaft seal member 57, which will be described later, cannot be formed, the reliability of the shaft seal member 57 cannot be guaranteed. For this,
The shaft seal member 57 is formed by forming a disk shape as in this embodiment.
An air pocket can be formed in the upper part of. In this case, the larger the size of the disk or blade, the higher the dissolution efficiency. However, in order to drive a large-sized stirring blade, the detergent stirring motor 3
It is necessary to increase the output of 9, and the detergent stirring motor 39
Becomes large, the size of the high-concentration detergent liquid generating means also becomes large, and it becomes difficult to store it in the back panel box 17. Further, problems such as water splash and cost increase occur. Therefore, in this embodiment, the blade has a triangular prism shape with a blade height of about 2 mm. Further, the outer diameter of the blade was reduced to about 50 mm, and the number of blades was set to 6 to 8. By doing so, the resistance received from the detergent solution during stirring can be reduced and the water splash can be reduced as compared with the standing plate-shaped blade. Further, by making the drive pulley 53 smaller than the driven pulley 52 and decelerating the rotation of the detergent agitating motor 39 and transmitting it to the detergent agitating blade 50, a small detergent agitating motor 39 with an output of 4 to 5 watts can be used. . The detergent stirring blade 50
The number of rotations of the detergent is the detergent dissolution performance, water splash, detergent stirring motor 3
Considering the output of 9, 2000-3000 rpm is good.

0c is placed in a radial gap between the outer peripheral surface of the sleeve 58 and the inner peripheral surface of the tubular portion 21z. By doing so, the gap between the tubular member 50c and the tubular portions 21b, 21z becomes a labyrinth and the labyrinth seal mechanism 60 can be configured. Since the upper surface of the shaft seal member 57 is higher than the bottom wall 21a4 and the labyrinth seal mechanism 60 is provided on the bottom wall 21a4, the gap 50d serves as an air reservoir, and when detergent or dissolved water is put in the detergent dissolving container 21, the gap is formed. Detergent and dissolved water do not enter up to 50d. In addition, the labyrinth mechanism 60 works during the rotation of the detergent stirring blade 50 to leave a gap of 5
The air accumulated in 0d is not discharged, and the detergent liquid does not enter the gap 50d.

止できる。Since the surface tension of the detergent liquid is small, the detergent liquid easily invades between the shaft seal member 57 and the stirring blade drive shaft 51 and causes a leak. Further, in the detergent liquid having a very high concentration as in this example, the concentration of zeolite insoluble in water contained in the detergent is also very high. Since zeolite has a very small particle size of 1 to 3 μm, it enters the shaft seal member 57 together with the detergent liquid. The entering zeolite damages the lip of the shaft seal member 57 and wears the stirring blade drive shaft 51, so that the detergent liquid leaks. However, by providing the labyrinth mechanism 60, the gap 50d is always filled with air, so that a high-concentration detergent liquid does not enter the shaft seal member 57. Therefore, the shaft seal member 57 and the stirring blade drive shaft 51 are prevented. It is possible to prevent the damage of and the leakage of the detergent liquid.

Further, the foaming of the detergent during stirring causes an apparent increase in the amount of the detergent liquid, which needs to be taken into consideration. In this embodiment, the capacity of the detergent dissolving chamber 21c is 600 mL, and the amount of detergent dissolving water is set to 150 to 200 mL. The amount of detergent-dissolved water is controlled by the opening time of the auxiliary water supply solenoid valve 22. The concentration of the high-concentration detergent liquid produced is determined by the detergent dissolving container 2
It depends on the amount of detergent (the amount of laundry 38 and the amount of wash water) put in 1. For example, the amount of washing water in a washing / drying machine having a washing capacity of 8 kg is about 24 to 68 L, and the high-concentration detergent liquid is 80 to 500 times the detergent concentration of washing water.

When 0 is opened, tap water is directly supplied to the water injection port 19, and the tap water is sprayed on the laundry 38 in the washing / dehydrating tank 2 for pre-water supply. The pre-water supply amount is set to an amount (4 to 10 L) at least from the uppermost surface of the laundry 38 to the portion of about several pieces of cloth. The pre-water supply is a spray of a high-concentration detergent liquid that is performed next to promote the penetration of the high-concentration detergent liquid into the laundry 38, and
This is done to prevent uneven color due to the fluorescent whitening agent contained in the detergent. The pre-water supply process is performed simultaneously with the high-concentration detergent liquid generation process of step 403. This is because, as described above, it takes 2 to 3 minutes to dissolve the detergent, and the washing time can be shortened by performing the pre-water supply step during this. Furthermore, since the time from the end of the pre-water supply to the end of the dissolution of the detergent is the deferment time, tap water can be sufficiently permeated into the laundry 38. For example, if the water supply flow rate from the main water supply solenoid valve 20 is 15 L per minute and the pre-water supply amount is 10 L, the pre-water supply ends in 40 seconds. If the detergent dissolution time is 2 minutes, a stationary time of 1 minute 20 seconds can be taken.

い。Step 405 With the detergent agitating blade 50 still rotating, the electric operation clutch mechanism 62 of the drive unit 6 is controlled to the dehydration / drying mode, and the drive motor 61 is operated at a low speed to wash and dewater the tub 2 and the agitating blade 4. While rotating at a low speed, the auxiliary water supply solenoid valve 22 is opened to supply water to the detergent dissolving chamber 21c. The high-concentration detergent liquid in the detergent dissolving chamber 21c is diluted and increased, the water level rises, overflows from the overflow edge 21h, and flows down from the overflow passage 21f to the mixing chamber 21v. Simultaneously with the auxiliary water supply solenoid valve 22, the main water supply solenoid valve 20 is opened to supply tap water from the washing water water supply passage 21e to the mixing chamber 21v.
Supply to. In the mixing chamber 21v, the high-concentration detergent liquid is diluted with a preferable high-concentration detergent liquid with tap water, and sprayed from the outlet 21s to the laundry 38 in the washing / dehydrating tub 2 to be permeated. The high-concentration detergent liquid changes its flow direction by the rectifying member 74 provided at the outflow port 21s and flows toward the lower side wall of the washing / dehydrating tub 2. This is done in order to efficiently apply water to the laundry stuck to the wall surface of the washing / dehydrating tub 2 in the rinsing step to be performed later in the dehydration after washing. Further, the flow velocity of the tap water from the main water supply solenoid valve 20 decreases due to the action of the rectifying member 75 provided in the mixing chamber 21v. This is because if the flow velocity is too fast, the tap water and the high-concentration detergent liquid cannot be sufficiently mixed, and the high-concentration detergent liquid having an excessively high concentration is applied to the laundry. During stirring, the siphon water flow mechanism 21j does not conduct due to the effect of the above-mentioned flow straightening plate 21m, but may conduct.

弁２２からの流量が少ない場合でも５倍以下となる。As described above, the concentration of the high-concentration detergent liquid to be sprayed on the laundry 38 is preferably about 5 to 20 times. Due to the water supply from the auxiliary water supply solenoid valve 22, the concentration of the detergent liquid in the detergent dissolving container 21c decreases, and the concentration of the high-concentration detergent liquid sprayed from the water injection port 19 also decreases. For example, if the tap water pressure is low, the flow rate of water supplied from the main water supply solenoid valve 20 is 5 L per minute, and the flow rate of water supplied from the auxiliary water supply solenoid valve 22 is 1 L per minute, then the water injection port is started approximately 50 seconds after starting this step. The concentration of the high-concentration detergent liquid sprayed from 19 is about 5 times. Further, when the tap water pressure is high and 15 L / min is supplied from the main water supply solenoid valve 20 and 2 L / min is supplied from the auxiliary water supply solenoid valve 22, the concentration becomes 5 times in about 25 seconds. However, if the main electromagnetic water supply valve 20 and the auxiliary electromagnetic water supply valve 22c are closed at this point and the spraying of the high-concentration detergent solution is stopped, the detergent solution concentration in the detergent dissolving container 21c is still about 30 to 40 times. The detergent liquid is discharged from the detergent dissolving container 21c by the siphon water passage mechanism 21j and sprayed on the laundry 38, but the concentration is still too high. Therefore, this step is 9
Do it for about 0 seconds. By doing so, the concentration of the detergent solution in the detergent dissolving container 21c becomes 5 times or less even when the tap water pressure is low and the flow rate from the auxiliary water supply solenoid valve 22 is small.

Can be easily removed from the laundry.

Since the flow rate through the small hole 4a is smaller than the spraying flow rate of the high-concentration detergent solution, the detergent solution is accumulated in the concave portion of the stirring blade 4. For this reason, the high-concentration detergent liquid can be efficiently included in the laundry, and uneven washing and high detergency can be obtained. The spraying flow rate of the high-concentration detergent liquid changes depending on the tap water pressure. As described above, at the minimum tap water pressure of 0.03 MPa, the flow rate from the main water supply solenoid valve 20 is 5 L / min, and the flow rate from the auxiliary water supply solenoid valve 22 is Since it is 1 L per minute, the total is 6 L per minute. Therefore, in order to store the detergent liquid in the concave portion of the stirring blade 4, the size and number of the small holes 4a may be determined so that the flow rate through the small holes 4a is about 1 to 2 L / min.

When the stirring is stopped, the water surface in the detergent dissolving chamber 21c is no longer like a mortar, and the water surface is below the overflow edge 21h, so that the overflow water is temporarily stopped. Also, a lot of bubbles remain on the water surface.
Since the water supply of the auxiliary water supply solenoid valve 22 is still continuing, the water level rises above the overflow edge 21h to start overflowing, and bubbles on the water surface flow out. And siphon water flow mechanism 21j
And the water in the detergent dissolving chamber 21c also begins to drain from the siphon water passage mechanism 21j. Siphon water flow mechanism 21j
When the auxiliary water supply solenoid valve 22 is closed after the start of the work, most of the water in the detergent dissolving chamber 22c can be discharged. However, if bubbles remain in the detergent dissolving chamber 21c, the bubbles enter the siphon water passage mechanism 21j, and the siphon water passage mechanism 21
j remains open (air does not enter the siphon water passage mechanism), and the next time water is supplied, the water immediately drains,
Water cannot be stored in the detergent dissolving chamber 21c.

The bubbles can be removed by continuing the water supply from the auxiliary water supply solenoid valve 22. Of course, it is necessary to make the drainage flow rate from the siphon water passage mechanism 21j smaller than the water supply flow rate from the auxiliary water supply solenoid valve 22 to ensure that the overflow edge 21h overflows. Further, in order to efficiently remove bubbles, the detergent stirring blade 50 may be intermittently rotated for a short time. By doing so, the water surface rises at the start of rotation of the detergent stirring blade 50, a large amount of bubbles can be discharged from the overflow edge 50h, and the side wall surface 2
The bubbles remaining around the siphon water passage mechanism 21j having a small gap with 1w move to the center of the detergent dissolving container 21c and are discharged from the overflow edge 21h. Specifically, after the lapse of 90 seconds, the detergent agitating blade 50 is rotated once every 20 to 30 seconds for about 5 seconds while water is still being supplied from the auxiliary water supply solenoid valve 22. If the rotation time is too long, bubbles will be generated excessively, so about 5 seconds is preferable. It is sufficient that the detergent stirring blade 50 is rotated intermittently twice. After the detergent stirring blade 50 is finally rotated, the overflow edge 21h
The auxiliary electromagnetic water supply valve 22 is left open to eliminate bubbles until it overflows (20 to 30 seconds), and then the auxiliary water supply solenoid valve 22 is closed. The water in the detergent dissolving chamber 21c is discharged from the siphon water passage mechanism 21j.

兼脱水槽２を回転させながら給水する必要はない。Step 407: The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened to start the supply of tap water (wash water). Note that this water supply may be performed at the same time as the cleaning for removing bubbles in step 405a. This supply of wash water is performed up to the amount of water determined in step 402, but is interrupted to detect the amount of cloth (a compress value) and the quality of the laundry 38 during the supply of water (at this point, the cleaning of step 405a is performed. If not completed, only the main water supply solenoid valve 20 is closed and the auxiliary water supply solenoid valve 22 is left open to continue cleaning). This interrupted water level is a water level preset in the microcomputer 16a and suitable for detecting the amount of compress and cloth quality. The washing / dehydrating tub 2 and the stirring blade 4 should be rotated at a low speed as in step 405. This is because when tap water is supplied, the detergent solution having a concentration of about 10 times that has permeated the laundry 38 is gradually diluted, but the washing / dehydrating tank 2 is rotated to wash the laundry 3
By supplying water while rotating 8, the detergent liquid in the laundry is uniformly diluted, and the variation in stain removal can be reduced. When water is supplied up to the suspended water level, washing and dewatering tank 2
Since the concentration of the detergent liquid therein is approximately doubled, it is not necessary to supply water while rotating the washing / dehydrating tank 2 thereafter.

The cloth quality is detected by interrupting the water supply at a predetermined low water level, controlling the electric operation clutch mechanism 62 of the drive device 6 in the stirring mode, urging the drive motor 61 for a short time to rotationally drive the stirring blades 4, A first deceleration characteristic (amount of compress) in inertial rotation at the time of de-energization is detected, and then water supply is restarted to replenish the wash water to a predetermined high water level, and then the water supply is interrupted to drive the drive motor of the drive device 6. 6
1 is urged for a short time to rotationally drive the stirring blade 4, the second deceleration characteristic in inertial rotation when deenergized is detected, and washing is performed based on the difference between the first damping characteristic and the second damping characteristic. The cloth quality of the object 38 is detected. This cloth quality detection control is omitted when it becomes unnecessary due to the initial setting. And, depending on the cloth quality,
Determine the time and water flow (strength of mechanical agitation) in the wash and rinse steps.
