る糸くずを採集可能としている。The operation of the above structure will be described. In the washing or rinsing process, after the clothes and the detergent are put into the inner tub 1, when the operation is started, the motor 11 is automatically supplied to the predetermined water level and then the motor 11 is rotated. The pulsator 2 is rotationally driven by the rotational force of the motor 11 via the drive mechanism section 12 to stir the clothes. Here, as the pulsator 2 rotates, the back blade 7 provided on the lower surface of the pulsator 2 sucks up the washing liquid in the lower part of the outer tub 8, discharges it through the circulation water passage 3, and discharges it from the discharge port 5, and drops it again on the water surface. This promotes dissolution of the detergent while circulating the washing liquid. Alternatively, by attaching a filter (not shown) to the discharge port 5, it is possible to collect the lint generated from the clothes.

To drive. Therefore, the clothes in the inner tub 1 are pressed against the inner peripheral surface of the inner tub 1 by the centrifugal force due to the rotation, and the clothes are dehydrated. The dehydrated liquid moves from the inner tank 1 to the outer tank 8 through a hole (not shown) provided in the inner tank 1 and the outer tank 8

を発生させる。In the conventional structure as described above, the shape of the inner tank cover is connected to the substantially annular flat portion provided at the bottom of the inner tank 1 and corresponds to the immediate outer wall of the pulsator, and the circulating water channel is formed. The inflow port 24 of 3 has a step portion 2 as shown in FIG. 10 so that foreign matter does not enter the gap between the pulsator 2 and the inflow port 24.
9 are formed. For this reason, among the circulating water introduced from the inflow port to the circulating water channel by the rotation of the pulsator, the circulating water flowing along the inner wall of the circulating water channel 4 forming the step 29 is on each surface forming the step inner wall surface. And turbulence is generated.

り出る水量及びその吐出勢いを激減させていた。In particular, since the step portion 29 is located near the inlet of the circulating water channel where the circulating water has the most force due to the rotation of the pulsator 2, a turbulent flow is also generated, and the turbulent flow separates it from the inner wall surface of the step portion. The flow of circulating water that forms a laminar flow from the outlet to the outlet inside the circulating water channel is disturbed to drastically reduce the amount of water discharged from the outlet 5 and its ejection force.

するだけとなってしまう。As a result, when the circulating water discharged from the discharge port is used for washing or rinsing, the opening is formed in a wide area along the outer circumference of the inner tank in order to sprinkle the circulating water evenly on the clothes exposed on the water surface. The circulating water discharged from the discharge port is not formed in a fan shape, and the circulating water moving from the inner tank wall surface to the central part in conjunction with the rotation of the pulsator also reduces the circulating water discharge force. However, it only moves slightly in the vicinity of the inner tank wall surface.

類から出る糸屑を回収する場合も、循環水量が激減する
ため、糸屑回収率も低下する。Further, even when a filter is attached to the discharge port to collect the lint discharged from the clothes, the amount of circulating water is drastically reduced, so that the lint collecting rate is also lowered.

The circulating water can be regulated at the position where the force of the water flow introduced into the circulating water channel is the strongest to prevent the generation of turbulent flow in the circulating water channel due to the stepped portion of the inner tank cover.

When the filter No. 5 was attached, the lint collection rate could be improved from 63.5% to 69.9%.
Further, since the circulation of the washing liquid is increased, the solubility of the detergent which has conventionally stayed between the inner tub 1 and the outer tub 8 is promoted, and the washing performance can be improved. Further, in order to increase the discharge momentum, the circulating water is sprinkled evenly on the clothes exposed on the water surface, and the circulating water discharged from the discharge port formed in a wide area along the outer circumference of the inner tank is also It is discharged from the entire surface of the opening and is formed in a fan shape so as to sufficiently cover the water surface, and washing water or water for rinsing can be evenly distributed over the clothes on the water surface. Also, when the circulating water moves from the wall surface of the inner tank to the center part in conjunction with the rotation of the pulsator, the circulating water moves vigorously from the vicinity of the wall surface of the inner tank to the center, and this is repeated. This can prevent uneven washing and uneven rinsing of clothes. Furthermore, since the rib 28 of the present embodiment is formed integrally with the inner tank cover 4, it is possible to improve the above-mentioned performance without providing another component and without increasing the cost.

などの効果が増すことは言うまでもない。Therefore, for example, when the pulsator 2 is rotated for 1 second, the circulating water amount is 400 cc as compared with the conventional 400 cc.
By providing the rib of the present invention, it becomes 460 cc, which is 15%
In the case where the discharge port 5 is equipped with a filter, the lint collection rate can be further improved from 63.5% to 73% by the increase of the circulating water amount. Further, it goes without saying that the effect of increasing the discharge range of the circulating water due to the improvement of the solubility of the detergent and the increase of the discharge momentum are increased.

回収率の向上も図ることができる。As described above, according to the first aspect of the present invention, a plurality of ribs are formed on the circulating water channel side of the step portion along the flow direction of the circulating water. The pulsator is formed by the plurality of ribs. It is possible to prevent the turbulent flow in the circulating water channel due to the stepped portion of the inner tank cover by regulating the circulating water introduced into the circulating water channel by the rotation of No. 1 at the position where the force of the water flow is the strongest. This increases the amount of circulating water and increases the discharge momentum,
By improving the dissolution rate of detergent and expanding the discharge range of washing water, cleaning efficiency is improved and uneven cleaning can be prevented. Further, it is possible to improve the collection rate of lint.
