However, it is effective to sprinkle the washing liquid over the entire washing / dehydrating tank as in the above-mentioned prior art in terms of early dissolution of washing and improvement of washing power. Providing a plurality of circulating water channels substantially reduces the tank volume, hinders the movement of clothes in the tank, and may cause uneven washing and insufficient cleaning power.
As a countermeasure for this, it is possible to project the part of the inner tub that forms the circulating water channel to the outside, but the gap with the outer tub made of synthetic resin that contains the washing and dehydrating tub becomes narrower,
Since the washing and dehydrating tubs are more likely to come into contact with the outer tub, there is a problem that the outer tub is upsized.

Thirdly, as shown in FIG. 6, the upper fluid balance ring 6 which is the rear surface of the discharge port is formed as an inclined surface toward the center of the inner tank 5, and the surface 28 of the cover 28 which constitutes the front surface.
e is also a slope facing the center of the inner tank 5 so that the shower is smoothly projected forward. Circulation channel cover 27,
29 has a height up to the middle of the wall surface of the inner tank, and the lower portion of the water guiding opening 2 is narrower than the circulating water channel covers 26 and 28 at the lower portion.
7a and 29a, and the discharge openings 27b and 29 are provided at the top.
b is provided toward the inside of the inner tank 5. FIG. 9 is an example of this, in which (a) is discharged so that the washing water hits the wall at the upper end of the discharge opening so that the washing water gathers at the center of the tub, and (b) has the same shape as the circulating water channel covers 26 and 28. Therefore, the washing water can be spread and discharged.

As described above, in order to improve the lint collection performance of the four circulating water channel covers and realize a wide area shower in the tank, it is important to improve the circulating water amount. FIG. 8 shows an example of the relationship between the total area of the dehydration hole (water return hole) 5a and the bottom surface water return hole 8a and the circulating water amount. As the amount of circulating water increases, the water level in the outer tub 4 fluctuates more and more, and apparently the height from the water surface to the discharge port becomes higher and the amount of circulating water cannot be maintained. Therefore, the water is pushed up into the circulating water channel cover. In the meantime, the outer tank 4 must always be replenished with water. Therefore, the body 5
The areas of b, the bottom portion 5c, and the return holes 5a, 8a provided in the lower fluid balance ring 8 are as large as possible.
Further, the ribs forming the water passages of these circulation water passage covers may be provided with a self-adhesive packing in order to enhance water tightness.
