Description

[Detailed explanation of the idea] The present invention relates to a balance ring for a dehydrator.

In a dehydrator, a balance ring as a balancer is provided above the dehydrating tank in order to prevent vibrations caused by unbalanced positions of clothes placed in the dehydrating tank.

There are various types of balance rings, but they are generally filled with liquid (salt water to prevent freezing), and the liquid moves through the balance ring to balance the clothes in the dehydration tank. .

However, this type of balance ring has the disadvantage that it generates vibrations due to the rapid movement of the filled liquid during startup.

The object of the present invention is to provide a balance ring for a dehydrator that does not have the above drawbacks.

Embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a dehydration tank, 2 is a dehydration tank, which has a dehydration hole 3 in the peripheral wall and the bottom, and a rotating shaft 4 is attached to the center of the bottom by a coupling 5.

The dewatering tank 1 has an opening 6 at the top for putting laundry in, a drain hole 7 at the bottom, and a rotary shaft 4 held by a flexible seal member 8.

9 is a balance ring of the present invention, which has a donut-shaped shape;
It is attached to the upper opening of the dehydration tank 2.

As shown in detail in FIG. 3, this balance ring 9 has an upper chamber 11 and a lower chamber 12 separated by a horizontal partition plate 10.
The lower chamber 12 holds a balancing liquid (salt water) 13.

The partition plate 10 has a large number of small holes (L14) and forms a gap 15 with the inner wall inside the balance ring.

Next, its effect will be explained.

When the dewatering tank 2 is stopped, the balance ring 9 is in a state as shown in FIG. 3A.

When the dehydration tank 2 starts rotating, the filled liquid 13 is pushed up by centrifugal force, passes through the small holes 14, and moves from the solid line to the dotted line as shown in the opening of Figure 3, and finally As shown in FIG. 3, the surface is vertical.

If this is viewed from a plane, as shown in FIG. 4, the liquid 13 is biased in the opposite direction to the uneven distribution of the laundry in the dehydration tank, thus achieving a balance as a whole.

By the way, in the conventional balance ring of this type, when the dehydration tank is started, the filling liquid in the balance ring moves violently, which causes vibrations, but in the present invention, from the stationary state shown in Figure 3A to the state shown in Figure 3 During the transition period leading to the constant speed rotation state of C, the state shown in Figure 3 is passed through, which prevents rapid transfer of the liquid 13 and reduces the occurrence of vibrations when starting the dehydration tank. be able to.

As described above, the present invention divides the interior of the donut-shaped balance ring 9 into an upper chamber 11 and a lower chamber 12 by a partition plate 10 having a large number of small holes 14, and a balance liquid 13 in the lower chamber.
In addition, since a gap 15 is formed between the partition plate 10 and the inner wall of the balance ring 9, rapid movement of the liquid 13 is prevented and vibrations are prevented when the dehydration tank is started. reduce the occurrence of

Further, when the dehydration tank is stopped, the liquid 13 that has moved to the upper chamber 11 flows back to the lower chamber 12 through the gap 15, and the state immediately returns to the state before starting.

Therefore, it is possible to provide a dehydrator that eliminates the drawbacks of the conventional dehydrator equipped with this type of balance ring mentioned at the beginning.
