Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a single-tub washing machine for general household use.

BACKGROUND ART A conventional one-tub type washing machine of this type is explained with reference to FIG. 3. Reference numeral 1 denotes a water receiving tank for receiving washing water, and a cover 2 is provided on the top, and a dewatering/washing tub 3 is provided inside. . This dewatering/washing tub 3 has a rotary blade 4 at the bottom, a passage 6 for a circulation filter 5 from the bottom to the side wall, and a fluid balancer 7 at the upper opening edge.
A reinforcing plate 9 that engages with the dewatering shaft 8 is disposed on the bottom back surface. 10 is a rinse case detachably disposed on the fluid balancer 7. Reference numeral 11 denotes a mechanical case having a clutch mechanism 12 that simultaneously rotates the rotary blade 4 during washing, and simultaneously rotates the rotary blade 4 and the dewatering/washing tub 3 during dewatering, and rotation from a motor 14 is transmitted via a V-belt 13. The water tank 1 is suspended and supported by an outer frame 17 by a rod 15 and a spring 16.

Problems to be Solved by the Invention In such a conventional configuration, when clothes are biased toward the lower part of the circulation filter 5 and the lower part of the rinse case 10 during dehydration, the cross section of the fluid balancer 7 is smaller than other parts, and the flow rate is reduced. Because of the small amount, the effect of maintaining balance could not be sufficiently exhibited, and vibrations at the time of starting dehydration tended to increase, making it impossible to obtain a uniform balance maintaining function. In addition, in order to make the cross-sectional area of the fluid balancer 7 of the attachment part of the circulation filter 5 and the rinse case 10 the same as that of other parts, the attachment part has to protrude in the inner diameter direction, which makes it difficult to put in and take out clothes. It was hot.

This invention solves these problems,
The purpose is to provide a sufficient balance maintaining function regardless of the unbalanced position of clothing.

Means for Solving the Problem In order to solve this problem, the present invention provides a spin-drying/washing tub equipped with a circulation filter and a fluid balancer with a removable rinse case, and a back side of the spin-drying/washing tub. The reinforcing plate is provided at the bottom and engages with the dewatering shaft, and the water receiving tank encloses the dewatering/washing tub. The cross-sectional area of the water receiving portion is set such that a portion corresponding to a lower position of the circulation filter and the rinse case of the fluid balancer is larger than other portions.

Function: With this configuration, the balance maintaining function works no matter where the clothes are biased during spin-drying, and it is possible to reduce and stabilize vibrations when starting spin-drying.

Embodiment Hereinafter, the drawings (first
This will be explained based on FIG. 2).

In the figure, 18 is an outer frame, and from the upper part of this outer frame 18, a rod 19 and a water receiving tank 21 are connected via a spring 20.
is supported in suspension. A cover 22 is provided on the top of the water tank 21, and inside the water tank 21,
A rotary blade 23 is provided at the bottom, a water passage 25 for the circulation filter 24 is provided from the bottom to the side wall, a fluid balancer 27 with the circulation filter 24 and rinse case 26 removably attached to the upper opening edge is engaged with a dewatering shaft 28 on the back surface of the bottom. A dewatering/washing tub 30 having a reinforcing plate 29 is provided. Reference numeral 31 designates a mechanical case having a clutch mechanism 32 that simultaneously rotates the rotary blade 23 during washing and the rotary blade 23 and the dewatering/washing tub 30 during dehydration, and rotation is transmitted from a motor 34 via a V-belt 33. Reference numeral 35 denotes a water receiving portion which is formed around the entire outer circumference of the reinforcing plate 29 and has an approximately-shaped cross section with an opening at the upper end, and has a plurality of radial ribs 36 formed inside. The cross-sectional area of the water receiving portion 35 is set to be larger at the portions located below the circulation filter 24 attachment portion and the rinse case 26 attachment portion of the dewatering/washing tub 30 than at other portions.

In the above configuration, water accumulates in the water receiver 35 when water is poured into the washing tank, and the centrifugal force of the spin rotation causes water to accumulate in the water receiver 35.
It remains until it is dispersed within 1. Therefore, when starting the dehydration process, the clothes are transferred to the circulation filter 2 of the dehydration/washing tub 30.
Even if the balance maintenance function of the fluid balancer 27 is insufficient due to bias toward the lower part of the 4-mounting part and the lower part of the rinse case 26-mounting part, the water flow in the water receiving part 35 fulfills the balancing function and the deficiency of the fluid balancer 27 is corrected. can be supplemented. In addition, the cross-sectional area of the water receiving portion 35 is the same as that of the circulation filter 24 of the dewatering/washing tub 30.
Since the lower part of the attachment part and the part located at the lower part of the rinse case 26 attachment part are set larger than other parts, the same balance maintaining function can be maintained no matter where the clothes are placed in the spin-washing tub 30. I can do it.

Effects of the invention As described above, according to the invention, a fluid balancer function is added to the reinforcing plate, and the cross-sectional area of the water receiving part corresponding to the lower position of the circulation filter and rinse case is set larger than the cross-sectional area of other parts. This is effective in reducing vibrations caused by unbalanced clothing when starting the dewatering process, and also equalizes the cross-sectional area of the water receiving part of the reinforcing plate and the cross-sectional area of the fluid balancer in each section, including the upper and lower cross-sectional areas. Because it becomes possible to
It is possible to reliably prevent the occurrence of abnormal vibrations at the time of start of dehydration even if the clothes are biased to any position of the dehydration/washing tub including the position below the circulation filter and the rinse case.

In addition, the water receiver is not a separate part, so it is inexpensive and requires no installation work.
