いる。For example, in the dewatering and washer 41, a liquid balancer is provided in the rotating tub to prevent the rotating tub from moving abnormally due to unbalanced distribution of laundry during dewatering. A conventional f-salary balancer supplies fluid to an annular chamber having a plurality of resistance plates intermittently in the circumferential direction, which are integrally formed to protrude from a bottom wall, for example, so as to leave a flow path for the liquid.
The structure is such that the flow of liquid is suppressed by a resistance plate when the rotating tank is below the resonant rotational speed, and when the rotating tank exceeds the resonant rotational speed, the liquid is It moves to the opposite side of the unevenly distributed position of the laundry, that is, the unbalanced load standing position, and absorbs the unbalance, and has extremely excellent vibration damping performance. However, recently, as dehydrating and washing machines have become larger, the unbalance that occurs has become extremely large and cannot be absorbed by the conventional liquid balancer. The development of a balancer with great capabilities is highly desired.

量とは反対側に寄−￥集まる。Next, the operation of the non-embodiment will be explained. When the rotating tank 4 is driven to rotate to start the cursed water operation, the liquid 12 and the sphere 13 are not subjected to a large centrifugal force during the low-speed rotation period below the resonance rotation speed, so the liquid 12 is rotated by the resistance plate. 16 suppresses movement in the circumferential direction, and the liquid 12 located around the sphere 13 suppresses movement in the circumferential direction as much as possible. Therefore, it is possible to prevent the inconvenience that the liquid 12 and the sphere 15 gather in the vertical direction of the unbalanced load below the resonance rotation speed and increase the amount of unbalance. Now, when the rotating tank 4 reaches the resonance rotation speed or higher, the gl, the body 12, and the ball holder 15 are transferred to the rotating tank 4.
Since the liquid 12 rotates substantially integrally with the annular chamber 10 and is sufficiently transported, the liquid 12 gathers on the outside of the annular chamber 10 due to centrifugal force, forming a cap that is pressed against the inner surfaces of both outer peripheral walls 18. At the same time, the sphere 16 is pushed against the annular wall 20 by centrifugal force. In this case, since almost no O body 12 exists around the floating body 16, the sphere 13 becomes able to move freely in the circumferential direction2, resulting in an unbalanced load in the rotating tank 4. If there is a season, the six-year-old beans 12 and the sphere 15 will gather on the side opposite to the unbalanced load bean amount.

体果が発揮される。In this case, if the amount of unbalance is less than the unbalance absorption limit by the return body 16, the spheres 16 will approach each other until the vibration amplitude becomes zero, and therefore the amplitude will become zero, so g, No movement of the ball 12 in the circumferential direction occurs, and a ball balancer effect is mainly produced. On the other hand, the unbalanced load is due to the unbalance caused by the sphere 16H'.
In addition, when the P range is exceeded, all the spheres 13 have already come together completely at this limit point, so the vibration system is in an unbalanced state, and the method to absorb this unbalance is iK salary 12 is %@I, 1. At night, the liquid fruit of the body is exhibited.

果が不安定になることはない。According to such a non-embodiment, the following effects are produced; namely, the mutual effect of the vehicle body balancer effect due to the liquid 12 in the annular chamber 10 and the ball balancer effect due to the sphere 16 provides an extremely large effect. Since the unbalance absorbing ability can be exhibited, a sufficient vibration damping effect can be obtained even with a large rotating tank 4. Further, since the annular wall 20 is provided protrudingly within the annular chamber 10, the sphere 13 will not be guided by the annular wall 20 and will not become circular or damage the resistance plate 16. The wall 20 is located at the tip of the resistance plate 16"416a
Since it is integrally molded so as to be inscribed in the annular wall 20, sufficient mechanical strength can be obtained.
It is sufficient that the wall thickness of the annular wall 20 does not need to be very large.Furthermore, a gap 21 of one position is formed between the upper end 20 of the annular wall 20 and the inner surface of the mounting member 14. Therefore, when the rotating tank 4 rotates, all of the liquid 12 located around the sphere 16 (between the annular wall 20 and the inner circumferential side wall 15) moves easily to the outer circumferential side wall 18 through the interval 21. Therefore, the presence of the annular wall 20 does not make the liquid balancer effect unstable.

とができる。Since the restraining body 23 is provided to protrude from the lid member 14, the vertical positioning of the sphere 15 is restrained by the restraining body 23, and the sphere 13 is prevented from moving upward from the upper end portion 20a of the annular wall 20. Of course, a stable ball balancer effect can be obtained without the ball protruding outward beyond the interval 21'.

ることができる利点がるる。In the above embodiment, the annular chamber 10 is provided with a non-porous annular wall 20 whose upper end 20a protrudes above the liquid level 12a of the temporary housing 12. As in the second embodiment of the invention, a plurality of through holes 200 may be formed in the annular wall 20, or as in the sixth embodiment of the invention shown in FIG. Instead of the wall 20, a linear wall 24 whose upper end 24a is located below the liquid level 12a of the liquid 12 may be provided.
According to the sixth embodiment, the liquid 12 located between the annular wall 20 or 24 and the inner peripheral side wall 15 during the low-speed rotation period of the resonance rotation speed of the rotating tank 4 passes through the through hole 20b. (the second embodiment) or beyond the upper end 24a of the annular wall 24 (the third embodiment), the liquid 12 can flow to the outer peripheral side wall 18 side. This has the advantage of being able to suppress the flow in the circumferential direction as much as possible.

Instead, a support step 15b for supporting the sphere 13 may be formed on the inclined portion 15a of the inner peripheral side wall 15. In this case, there is an advantage that the moldability of the annular gauge 9 is improved.

のである。As explained above, the present invention can greatly increase the unbalance absorbing capacity due to the mutual effect of the liquid balancer effect and the pole balancer effect, and the ball collides with the resistance plate for suppressing the flow of the liquid. This provides an excellent effect in that there is no problem of collision noise or damage to the resistance plate.
