。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating tub of a washing machine for dewatering and washing, in which an annular portion for storing liquid as a balance weight is integrally formed at the upper end of the rotating tub body for plastic acid.

従来、この種脱水兼用洗濯機においては回転槽本体とは
別個に断面Ｕ字形の環状体を形成して該環状体を回転槽
本体の上端内周部に嵌合固着するとともに該環状体の内
部にバランスウェイトとしての液体を収納した後に該環
状体の上面を環状のカバ一部材で液密に被う構成として
いるから、組立時間が多くかかつてコスト高であるとと
もに各部品の製作誤差及び組立誤差によって偏重心が生
じて振動を起し易い欠点がある。Conventionally, in this type of dehydrating/washing machine, an annular body having a U-shaped cross section is formed separately from the rotary tub body, and the annular body is fitted and fixed to the inner periphery of the upper end of the rotary tub body, and the inside of the annular body is After storing liquid as a balance weight in the annular body, the upper surface of the annular body is liquid-tightly covered with an annular cover member, which requires a lot of assembly time, is expensive, and is prone to manufacturing errors and assembly of each part. There is a drawback that the error causes an eccentric center of gravity, which tends to cause vibration.

そこで、近時回転槽本体に環状体をプラスチックで一体
成形することが考えられているが、型抜きの都合で該環
状体を回転槽本体の外周部側にしか形成できないから、
回転槽を内部に配設する水受槽の大きさが同一である場
合に、環状体を回転槽本体の外周部に設けるものは上述
したように環状体を回転槽本体の内周部に設けるものに
比べると回転槽本体の内径寸法が環状体の巾寸法の２倍
に相当する寸法だけ径小となり、その分洗濯容量が低下
するという別な問題を生ずる。Therefore, it has recently been considered to integrally mold an annular body with the rotary tank main body from plastic, but due to mold cutting, the annular body can only be formed on the outer peripheral side of the rotary tank main body.
When the size of the water receiving tank in which the rotating tank is placed inside is the same, the annular body is installed on the outer periphery of the rotating tank body as described above. Compared to this, the inner diameter of the rotating tub body is smaller by a dimension equivalent to twice the width of the annular body, which causes another problem in that the washing capacity decreases accordingly.

本考案は上記事情に鑑みてなされたものであり、その目
的は、回転槽本体の上端外周部に比較的幅狭で且つ縦長

ができる脱水兼用洗濯機の回転槽を提供するにある。The present invention has been developed in view of the above circumstances, and its purpose is to form a relatively narrow and vertically elongated annular portion on the outer periphery of the upper end of the rotary tank body by integral molding of plastic. It is easy to assemble, which reduces costs, and of course prevents vibrations caused by an eccentric center of gravity.The inner diameter of the rotating tub body can be set as large as possible, so there is almost no decrease in washing capacity, and in addition, it dehydrates well. This is to provide a rotating tub of a washing machine that can be used for both dehydration and washing.

An opening 11 is formed so as to communicate with the inside of the water receiving tank 2 through the communication port 10a.

１２は回転槽本体８の上端外周部にプラスチックの一体
成形によって設けた上端が開放する環状部で、これは比
較的幅狭で且つ縦長な形状に設定している。Reference numeral 12 denotes an annular portion whose upper end is open and is integrally molded with plastic and provided on the outer circumferential portion of the upper end of the rotary tank body 8, and is set in a relatively narrow and vertically elongated shape.

１３は環状部１２の底部壁を上方に略逆Ｕ字形に膨出さ

転槽３の揺動を抑制するバランスウェイトとして作用す
る。Next, to explain the operation of this embodiment configured as above, when the timer device 18 is set, a series of washing, rinsing, and spin-drying programs are executed as is well known. When the liquid 15 is driven to rotate
acts as a balance weight to suppress the swinging of the rotating tub 3 caused by the skewing of the laundry in the rotating tub 3.

そして、環状部１２の底部壁に設けた膨出逃げ部１３に
よって環状部１２内の液体１５が周方向に移動すること
がある程度抑制されるから、脱水運転の初期に回転槽３
が横振れを起すことが極力防止される。Since the liquid 15 in the annular part 12 is prevented from moving in the circumferential direction to some extent by the bulging relief part 13 provided on the bottom wall of the annular part 12, the rotation tank 3
This prevents sideways vibration as much as possible.

。According to this embodiment configured in this manner, the annular portion 12 is set to a relatively narrow and vertically long shape, and a plurality of bulging relief portions 13 are provided on the bottom wall of the annular portion 12, and the rotation Since the dewatering hole 14 located at the upper part of the side wall 8a of the tank body 8 is configured to correspond to the bulge escape part 13, the annular body 12 is connected to the rotary tank body 8 while setting the inner diameter of the rotary tank body 8 as large as possible. It can be provided on the outer periphery of the upper end by integral molding of plastic, and compared to the conventional structure in which the rotating tank main body and the annular body are formed separately and assembled, the eccentric center of gravity due to assembly error is eliminated, and the rotating tank 3 Vibrations accompanying the rotation of the tub are greatly reduced, assembly is simple, and production costs can be reduced, and the inner diameter of the rotary tub body 8 can be set as large as possible, with little reduction in washing capacity.

そして、環状部１２が縦長に形成されているにもかかわ

ち込むことが確実に防止される。In the above embodiment, since the cloth popping-out prevention part 17 is extended to the cover member 16, the water surface of the washing water becomes a so-called mortar shape during washing and rinsing, and the water level near the side wall 8a of the rotary tub main body 8 is lowered. Even when the water rises, the laundry is reliably prevented from jumping out of the rotating tub main body 8 and falling into the gap between the rotating tub 3 and the water receiving tank 2.

本考案は以上の説明から明らかなように、組立が簡単と
