の結果正常な脱水作用が行なわれない場合があった。Problems to be Solved by the Invention However, with such a structure, if the laundry (not shown) in the washing and dehydrating tub 2 is unevenly distributed during washing, the moment acting on the laundry during dehydration will cause the washing and dehydrating tub to become uneven. The dehydration tank 2 is subjected to an eccentric force in the direction perpendicular to the outer circumferential direction, and the outer tank 4 suspended by the support rod 15 is subjected to large vibrations in the horizontal and vertical directions. At this time, vibrations in the vertical direction of the outer tank 4 are mainly damped by the vibration-absorbing spring 22 and weight 23 so as not to be transmitted to the main body 1. In some cases, the dehydration process is not able to absorb the vibrations of the dehydration device, causing the dehydration to collide with the main body 1 or causing the safety switch to be activated immediately.
そこで、本発明は洗濯物が洗濯兼脱水槽内に偏って分布

すなわち、洗濯物が偏って分布しても、本発明では脱水
起動時に支持棒の中間付近に固着した重りの働きによシ
外槽の水平方向の振動を抑えることができる。That is, even if the laundry is unevenly distributed, in the present invention, horizontal vibration of the outer tub can be suppressed by the action of the weight fixed near the middle of the support rod at the time of start of dewatering.
この結果洗濯物が洗濯兼脱水槽内で偏って分布しても脱
水起動時に外槽が本体に衝突せず、円滑な脱水が行なえ

実施例
以下、本発明の一実施例を添付図面にもとづいて説明す
る。Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

Reference numeral 24 denotes a circular buffer tube formed integrally with the spherical body 19, and a spring receiver 25 is provided at the bottom of the compression spring 2o. Vertical vibration is damped by sliding it up and down.

く設計されている。A weight 26 is placed near the middle of the support rod 15 made of an elastic metal body.
is fixed, and the natural frequency of the system consisting of the weight 26 and the support rod 15 is designed to be approximately equal to the free frequency of horizontal rocking when the outer tub 4 and the washing/dehydration tub 2 are supported by the support rod 15. ing.

次に、この一実施例の構成における作用を説明する。洗
な時において洗濯兼脱水槽２．および外槽４内に洗濯水
を入れると、その重量によって外槽４は下降する。この
下降により圧縮スプリング２゜は圧縮された状態となる
。そして洗濯時においては攪拌翼６が回転し、洗濯物が
水流により動くのみであるため、外槽４の振動は比較的
少ない、したがって充分吸振がなされる。Next, the operation of the configuration of this embodiment will be explained. Washing/dehydration tank when washing is needed 2. When washing water is poured into the outer tub 4, the outer tub 4 descends due to its weight. This lowering causes the compression spring 2° to be in a compressed state. During washing, the stirring blades 6 rotate and the laundry is moved only by the water flow, so the vibrations of the outer tub 4 are relatively small, so that vibrations are sufficiently absorbed.
一方、脱水時においては、外槽４内の洗濯水は外部に排
出されるので、外槽４の重量はしだいに減少する。この
減少に伴なって圧縮スプリング２０はや＼伸びた状態と
なり、脱水の開始とともに洗濯物が偏って分布すること
により生じる外槽４の振動を吸収する。On the other hand, during spin-drying, the washing water in the outer tub 4 is discharged to the outside, so the weight of the outer tub 4 gradually decreases. With this decrease, the compression spring 20 becomes slightly expanded and absorbs the vibration of the outer tub 4 caused by uneven distribution of the laundry at the start of dewatering.

ルギー伝達が大きくなり、使用者に不快感を与えるため
低い値に抑えている。したがって洗濯物の偏りが非常に
大きい場合には、外槽４の水平方向の振動を充分に吸収
できない。In general, vibrations during dehydration can be broadly divided into horizontal vibrations and vertical vibrations. And for horizontal vibration, upper and lower spherical bodies 14.19 and upper and lower supports 13
．． This is damped by the sliding friction between the main body 18, but if the frictional resistance is large during steady high-speed rotation, the energy transmission to the main body 1 will be large, causing discomfort to the user, so it is kept to a low value. Therefore, if the laundry is extremely uneven, horizontal vibrations of the outer tub 4 cannot be absorbed sufficiently.

なければならないというような不都合は生じない。又、
この振動抑制作用は共振状態に有効に働くものであり、
定常回転時に、悪影響を及ぼす事はない。However, since the weight 26 is fixed near the middle of the support rod 16, the outer tank begins to vibrate horizontally when dewatering starts.
When the support of the outer tank enters a horizontal rocking resonance state, and the outer tank swings widely in the horizontal direction, the vibration of the weight 16 causes this outer tank 4 to vibrate.
As a result, the outer tank 4 stands up without colliding with the main body 1 at the start of dewatering, and smooth rotation starts. In addition, there is no need to stop the operation or restart the system after rinsing again, which is the case in the past. or,
This vibration suppression effect works effectively in resonance conditions,
There is no adverse effect during steady rotation.

Due to the so-called vibration-absorbing effect of the weight and support rod, even if the outer tank becomes in a state of vibration resonance during startup, the vibration is suppressed, and the outer tank can smoothly start and dehydrate without colliding with the main body. Can be done.
