Description

【0001】
【発明の属する技術分野】
本発明は、略水平方向の回転軸を中心に回転自在に配設したドラム内で洗濯物を洗濯、すすぎ、脱水するドラム式洗濯機に関するものである。
【0002】
【従来の技術】
従来、この種のドラム式洗濯機は図4および図5に示すように構成していた。以下、その構成について説明する。
【0003】
図4に示すように、回転ドラム1は、外周部に多数の通水孔2を全面に設け、外槽3内に回転自在に配設している。回転ドラム1の回転中心に回転軸4の一端を略水平方向に固定し、回転軸4の他端にドラムプーリー5を固定している。駆動モータ6は、ベルト7によりドラムプーリー5と連結し、ドラム1を回転駆動する。
【0004】
外槽3は、ボデー8よりばね体9で揺動可能に吊り下げ、防振ダンパー10により脱水起動時の振動が低減され、定常脱水時の振動がボデー8に伝達されないように防振支持するとともに、脱水時の振動を低減する重り11を設けている。略筒状のパッキング部材12は、回転ドラム1の前面開口部13に対応する外槽3の開口部14とボデー前面開口部15との間を連結するものである。ボデー前面開口部15に窓16を開閉自在に設けている。
【0005】
ヒータ17は、外槽3内の洗濯水を加熱するものである。制御装置18は、駆動モータ6、ヒータ17などの動作を制御し、洗濯、すすぎ、脱水などの一連の行程を逐次制御する。
【0006】
パッキング部材12は、図5に示すように、ボデー8を折り曲げた端部8aにボデー側端部19を嵌合し、ばね状のバンド20によりボデー8に固着し、外槽側端部21は、外槽3を折り曲げた端面3aに嵌合し、バンド22により外槽3に固着している。また、パッキング部材12は、略同一の肉厚で、その長さ方向を部分的に後方かつ内方へ折り返して略環状の膨出部23を形成している。
【0007】
上記構成において動作を説明すると、窓16を開いて回転ドラム1内に洗濯物を投入し、運転を開始すると、洗濯行程では、回転ドラム1は駆動モータ6によって第1の回転数N1(約53rpm)で回転駆動され、回転ドラム1内の洗濯物は持ち上げられて水面上に落下される。こうして洗濯行程が進行する。すすぎ行程においても洗濯行程と同様の動作を行う。
【0008】
脱水行程では、回転ドラム1は第2の回転数N2(約1000rpm)で回転駆動され、洗濯物は遠心脱水される。このとき、回転ドラム1内の洗濯物の片寄り、すなわちアンバランスが生じると、回転ドラム1、外槽3などの揺動体は振動(揺動)するが、脱水起動時は防振ダンパー10により揺動体の振動を減衰し、定常脱水時は防振ダンパー10の防振機構によりボデー8に伝達されることはない。また、外槽3の開口部14とボデー8の前面開口部15との間を略筒状のパッキング部材12により連結しているが、揺動体の揺動により略筒状のパッキング部材12がたわむことにより、略筒状のパッキング部材12を通してボデー8に振動が伝達されることはない。
【0009】
【発明が解決しようとする課題】
このような従来の構成では、回転ドラム1の回転により、回転ドラム1内の洗濯物は、回転すると同時に前後方向に移動し、パッキング部材12に接触しながら回転する。このとき、洗濯物はパッキング部材12の折り返し部24に当たるため、パッキング部材12が摩耗して破れ、水漏れが発生することがあり、また、運転時に膨出部23に溜まった水が飛び上がり、回転ドラム1内の洗濯物を濡らすという問題を有していた。
【0010】
また、パッキング部材12の折り返し部24と、この折り返し部24と対向した位置に設けたリブ25に接触したときの接触面積が大きく、運転時に折り返し部24がリブ25に当たったとき、大きな衝撃音を発生するという問題を有していた。
【0011】
本発明は上記従来の課題を解決するもので、パッキング部材の破れによる水漏れが発生するのを防止することを目的としている。
【0012】
【課題を解決するための手段】
本発明は上記目的を達成するために、略水平方向に回転軸を有する回転ドラムを外槽により外包し、外槽を主体とする揺動体を揺動可能にボデーに収容し、洗濯時および脱水時に駆動モータにより回転ドラムを回転させる。回転ドラムの前面開口部に対応する外槽の開口部とボデー前面開口部との間を略筒状のパッキング部材で連結し、パッキング部材は、その長さ方向を部分的に後方かつ内方へ折り返すことにより外周側に膨出した膨出部を形成し、パッキング部材の内方へ折り返した内方突出部の先端には、膨出部を部分的に覆い径方向の厚みが回転軸方向の高さ寸法より小さい略環状の障壁部を一体に形成するとともに、回転ドラムの前面開口部と略環状の障壁部との間に略環状の障壁部に対向するようにリブを設けたものである。
【0013】
これにより、洗濯行程またはすすぎ行程で、回転ドラムを回転させると、回転ドラムの回転により回転ドラム内の洗濯物は回転するとともに前後方向に移動し、パッキング部材に接触しながら回転し、このため、洗濯物はパッキング部材のリブに当たったり、乗り越えたりしながら回転するが、洗濯物は略環状の障壁部に当たるため、略環状の障壁部が多少摩耗するがパッキング部材が破れることがなく、パッキング部材の破れによる水漏れが発生するのを防止することができる。
【0014】
【発明の実施の形態】
請求項に記載の発明は、略水平方向に回転軸を有する回転ドラムと、この回転ドラムを外包した外槽と、洗濯時および脱水時に前記回転ドラムを回転させる駆動モータと、前記外槽を主体とする揺動体を揺動可能に収容したボデーと、前記回転ドラムの前面開口部に対応する外槽の開口部とボデーの前面開口部との間を連結した略筒状のパッキング部材とを備え、前記パッキング部材は、その長さ方向を部分的に後方かつ内方へ折り返すことにより外周側に膨出した膨出部を形成し、前記パッキング部材の内方へ折り返した内方突出部の先端には、前記膨出部を部分的に覆い径方向の厚みが回転軸方向の高さ寸法より小さい略環状の障壁部を一体に形成するとともに、前記回転ドラムの前面開口部と前記略環 状の障壁部との間に前記略環状の障壁部に対向するようにリブを設けたものであり、回転ドラムの回転により回転ドラム内の洗濯物が回転するとともに前後方向に移動し、パッキング部材に接触しながら回転し、このとき、洗濯物はパッキング部材の略環状の障壁部に当たるため、略環状の障壁部が多少摩耗するがパッキング部材が破れることがなく、パッキング部材の破れによる水漏れが発生するのを防止することができる。また、略環状の障壁部により、外周側に形成した膨出部に溜まった水の飛び上がりを防止することができ、回転ドラム内の洗濯物を濡らすのを防止することができる。さらに、略環状の障壁部がこの障壁部と対向した位置に設けたリブに接触したときの接触面積を小さくすることができ、運転時に障壁部がリブに当たったときに発生する衝撃音を小さくすることができ、また、金型の肉厚確保による金型の耐久性を向上することができる。
【0015】
【実施例】
以下、本発明の一実施例について、図1から図3を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。
【0016】
図3に示すように、第1のモータ(駆動モータ)26は、回転ドラム1を第1の回転数N1(たとえば、53rpm)で回転させて、洗濯またはすすぎをするものであり、第2のモータ(駆動モータ)27は、回転ドラム1を第2の回転数N2(たとえば、1000rpm)で回転させて脱水する。これら第1のモータ26および第2のモータ27は、インダクションモータで構成し、それぞれベルト28、29を介して従動プーリー30に連結している。
【0017】
従動プーリー30は、2種の減速比を有しており、第1のモータ26をベルト28を介して減速比が大きい従動プーリー30aと連結し、第2のモータ27をベルト29を介して減速比が小さい従動プーリー30bと連結し、回転ドラム1の回転中心に一端を固定した回転軸4の他端に固定している。制御装置31は、ヒータ17、第1のモータ26、第2のモータ27などの動作を制御し、洗濯、すすぎ、脱水などの一連の行程を逐次制御する。
【0018】
パッキング部材32は、ゴムにより略筒状に形成し、回転ドラム1の前面開口部13に対応する外槽3の開口部14とボデー前面開口部15との間を連結するものである。このパッキング部材32のボデー側端部33に、図1および図2に示すように、略環状の取り付け部材34を取り付け、この略環状の取り付け部材34にボデー8の前面側からねじ35とナット36により締着し、パッキング部材32のボデー側端部33を略環状の取り付け部材34とボデー前面開口部15の周縁内面部とで挟持している。
【0019】
取り付け部材34は略環状であるため、構成を簡素化することができ、この取り付け部材34をパッキング部材32にはめ込み、取り付け部材34とボデー前面開口部15の周縁内面部とでパッキング部材32を挟持するだけでよいため、組立作業性、サービス性を向上することができる。
【0020】
また、パッキング部材32は、その長さ方向を部分的に後方かつ内方へ折り返して膨出部37を形成し、その内方突出部先端に、パッキング部材32の径方向の厚みAより大きい高さBを有する略環状の障壁部38を一体に形成し、この略環状の障壁部38に対向してリブ39を設けている。
【0021】
上記構成において動作を説明すると、窓16を開いて回転ドラム1内に洗濯物を投入し、電源スイッチ(図示せず)をオンした後、制御装置31に設けたスタートスイッチ(図示せず)を操作して運転を開始すると、給水弁40が動作して給水し、水位検知手段(図示せず)により所定の水位を検知すると給水を停止し、第1のモータ26を駆動する。洗濯行程では、洗濯物に水が含まれるため補給水しながら、回転ドラム1は第1のモータ26によって第1の回転数N1で回転駆動され、回転ドラム1内の洗濯物は持ち上げられて水面上に落下される。
【0022】
このとき、ヒータ17に通電して外槽3内の洗濯水をほぼ一定の温度に制御しながら加熱する。洗濯行程が終了すると、排水ポンプ41が動作して外槽3内の洗濯水を排水する。その後、すすぎ行程を経由して脱水行程では、回転ドラム1は第2の回転数N2で回転駆動され、洗濯物は遠心脱水される。
【0023】
洗濯行程またはすすぎ行程で、回転ドラム1を第1の回転数N1で回転させると、回転ドラム1の回転により回転ドラム1内の洗濯物は回転するとともに前後方向に移動し、パッキング部材32に接触しながら回転する。このため、洗濯物はパッキング部材32のリブ39に当たったり、乗り越えたりしながら回転するが、洗濯物は略環状の障壁部38に当たるため、略環状の障壁部38が多少摩耗するがパッキング部材32が破れることがなく、パッキング部材32の破れによる水漏れが発生するのを防止することができる。
【0024】
また、脱水行程で、回転ドラム1を第2の回転数N2で回転させたとき、回転ドラム1内の洗濯物がアンバランス状態であると、外槽3を主体とする揺動体が振動(揺動)し、この振動によってパッキング部材32は膨出部37が伸縮することにより、略水平方向に伸縮を繰り返す。このとき、膨出部37に溜まった水が飛び上がろうとするが、略環状の障壁部38により水の飛び上がりを防止することができ、この飛び上がった水によって回転ドラム1内の洗濯物を濡らすのを防止することができる。
【0025】
また、略環状の障壁部38は、その径方向の厚みAを高さ寸法Bより小さくしているので、パッキング部材32が膨出部37の伸縮によって、略水平方向に伸縮を繰り返すことで、障壁部38がリブ39に当たったときに発生する衝撃音などの異常音を小さくすることができる。
【0026】
このように本実施例によれば、略筒状のパッキング部材32のボデー側端部33をボデー前面開口部15の周縁内面部とで挟持する取り付け部材34を略環状とすることで、取り付け部材34の構成を簡素化することができ、取り付け部材34をパッキング部材32にはめ込み、取り付け部材34とボデー前面開口部15の周縁内面部とでパッキング部材32を挟持するだけでよいため、組立作業性、サービス性を向上することができる。
【0027】
また、取り付け部材34の開口端部34aによりパッキング部材32との押さえ代を調整することにより、パッキング部材32と窓16の内面との嵌着力を調整することができるため、窓16の内面とパッキング部材32との間の隙間から水が漏れるのを防止することができ、また、窓16の開閉力を調整することもできる。また、略環状の取り付け部材34とボデー前面開口部15の周縁とを、ボデー8の前面側からねじ35により締着し固定するので、組立作業性およびサービス性を向上することができる。
【0028】
なお、本実施例では、略環状の取り付け部材34の締着に、ねじ35とナット36を用いているが、ナット36の代わりに、取り付け部材34にバーリングを設け、そこにねじ加工を行った形状としても、同様の作用効果を得ることができる。
【0029】
【発明の効果】
以上のように本発明の請求項1に記載の発明によれば、略水平方向に回転軸を有する回転ドラムと、この回転ドラムを外包した外槽と、洗濯時および脱水時に前記回転ドラムを回転させる駆動モータと、前記外槽を主体とする揺動体を揺動可能に収容したボデーと、前記回転ドラムの前面開口部に対応する外槽の開口部とボデーの前面開口部との間を連結した略筒状のパッキング部材とを備え、前記パッキング部材は、その長さ方向を部分的に後方かつ内方へ折り返すことにより外周側に膨出した膨出部を形成し、前記パッキング部材の内方へ折り返した内方突出部の先端には、前記膨出部を部分的に覆い径方向の厚みが回転軸方向の高さ寸法より小さい略環状の障壁部を一体に形成するとともに、前記回転ドラムの前面開口部と前記略環状の障壁部との間に前記略環状の障壁部に対向するようにリブを設けたから、回転ドラムの回転により回転ドラム内の洗濯物が回転するとともに前後方向に移動した場合でも、洗濯物はパッキング部材の略環状の障壁部に当たるため、略環状の障壁部が多少摩耗するがパッキング部材が破れることがなく、パッキング部材の破れによる水漏れが発生するのを防止することができる。また、略環状の障壁部により、外周側に形成した膨出部に溜まった水の飛び上がりを防止することができ、回転ドラム内の洗濯物を濡らすのを防止することができる。さらに、略環状の障壁部がこの障壁部と対向した位置に設けたリブに接触したときの接触面積を小さくすることができ、運転時に障壁部がリブに当たったときに発生する衝撃音を小さくすることができ、また、金型の肉厚確保による金型の耐久性を向上することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a drum type washing machine for washing, rinsing, and dewatering laundry in a drum that is rotatably arranged around a substantially horizontal rotation axis.
[0002]
[Prior art]
Conventionally, this type of drum-type washing machine is configured as shown in FIGS. Hereinafter, the configuration will be described.
[0003]
As shown in FIG. 4, the rotating drum 1 is provided with a large number of water passage holes 2 on the entire outer periphery thereof, and is rotatably disposed in the outer tub 3. One end of the rotary shaft 4 is fixed in a substantially horizontal direction at the rotation center of the rotary drum 1, and a drum pulley 5 is fixed to the other end of the rotary shaft 4. The drive motor 6 is connected to the drum pulley 5 by a belt 7 and rotationally drives the drum 1.
[0004]
The outer tub 3 is suspended from the body 8 by a spring body 9 so as to be swingable, and the vibration isolating damper 10 reduces vibration at the time of dehydration start and supports the vibration isolation so that the vibration at the time of steady dehydration is not transmitted to the body 8. In addition, a weight 11 for reducing vibration during dehydration is provided. The substantially cylindrical packing member 12 connects the opening 14 of the outer tub 3 corresponding to the front opening 13 of the rotating drum 1 and the body front opening 15. A window 16 is provided in the body front opening 15 so as to be opened and closed.
[0005]
The heater 17 heats the washing water in the outer tub 3. The control device 18 controls operations of the drive motor 6 and the heater 17 and sequentially controls a series of processes such as washing, rinsing, and dehydration.
[0006]
As shown in FIG. 5, the packing member 12 has a body side end 19 fitted to the end 8 a bent from the body 8, and is fixed to the body 8 by a spring-like band 20. The outer tub 3 is fitted to the bent end surface 3 a and fixed to the outer tub 3 by the band 22. Further, the packing member 12 has substantially the same thickness, and its length direction is partially folded back and inward to form a substantially annular bulging portion 23.
[0007]
In the above configuration, the operation will be described. When the window 16 is opened and the laundry is put into the rotary drum 1 and the operation is started, the rotary drum 1 is driven by the drive motor 6 at the first rotational speed N1 (about 53 rpm) in the washing process. The laundry in the rotary drum 1 is lifted and dropped onto the water surface. Thus, the washing process proceeds. In the rinsing process, the same operation as in the washing process is performed.
[0008]
In the dehydration process, the rotary drum 1 is rotationally driven at the second rotation speed N2 (about 1000 rpm), and the laundry is centrifugally dehydrated. At this time, if the laundry in the rotating drum 1 is shifted, that is, if an imbalance occurs, the rotating bodies such as the rotating drum 1 and the outer tub 3 vibrate (oscillate). The vibration of the rocking body is attenuated and is not transmitted to the body 8 by the vibration isolating mechanism of the vibration isolating damper 10 during steady dehydration. Further, the opening 14 of the outer tub 3 and the front opening 15 of the body 8 are connected by a substantially cylindrical packing member 12, but the substantially cylindrical packing member 12 bends due to the swinging of the swinging body. Thus, vibration is not transmitted to the body 8 through the substantially cylindrical packing member 12.
[0009]
[Problems to be solved by the invention]
In such a conventional configuration, by rotation of the rotary drum 1, laundry in the rotary drum 1, rotates and moves in the longitudinal direction at the same time, rotates while contacting the packing member 12. At this time, since the laundry hits the folded portion 24 of the packing member 12, the packing member 12 may be worn and torn and water leakage may occur. Also, water accumulated in the bulging portion 23 during operation jumps up and rotates. There was a problem of wetting the laundry in the drum 1.
[0010]
Further, the contact area is large when contacting the folded portion 24 of the packing member 12 and the rib 25 provided at a position facing the folded portion 24, and when the folded portion 24 hits the rib 25 during operation, a large impact sound is generated. Had the problem of generating.
[0011]
SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to prevent water leakage due to tearing of a packing member.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the present invention encloses a rotating drum having a rotating shaft in a substantially horizontal direction by an outer tub, and a swinging body mainly composed of the outer tub is swingably accommodated in a body so that it can be washed and dehydrated. Sometimes the rotating drum is rotated by a drive motor. The opening of the outer tub corresponding to the front opening of the rotating drum and the front opening of the body are connected by a substantially cylindrical packing member, and the packing member partially extends backward and inward in the length direction. A bulging portion that bulges to the outer peripheral side is formed by folding back, and the bulging portion is partially covered at the tip of the inward protruding portion that is folded inward of the packing member so that the radial thickness is in the direction of the rotation axis. A substantially annular barrier portion smaller than the height dimension is integrally formed, and a rib is provided between the front opening of the rotating drum and the substantially annular barrier portion so as to face the substantially annular barrier portion. .
[0013]
Accordingly , when the rotating drum is rotated in the washing process or the rinsing process , the laundry in the rotating drum rotates and moves in the front-rear direction by the rotation of the rotating drum, and rotates while contacting the packing member. The laundry rotates while hitting or getting over the ribs of the packing member, but since the laundry hits the substantially annular barrier portion, the substantially annular barrier portion is worn slightly, but the packing member is not torn, and the packing member It is possible to prevent water leakage due to tearing .
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 includes a rotating drum having a rotating shaft in a substantially horizontal direction, an outer tub enclosing the rotating drum, a drive motor for rotating the rotating drum during washing and dehydration, and the outer tub. A body housing a main oscillating body in a swingable manner, and a substantially cylindrical packing member connecting between an opening of the outer tub corresponding to the front opening of the rotating drum and the front opening of the body. wherein the packing member forms a bulging portion that bulges to the outer peripheral side by Succoth return folding its lengthwise into partial rear and inward, inwardly projecting folded back inwardly of said packing member At the tip of the part, a substantially annular barrier part that covers the bulging part partially and has a radial thickness smaller than the height dimension in the rotation axis direction is formed integrally with the front opening of the rotary drum and the the substantially annular between Ryakuwa shaped barrier portion Are those having a rib provided so as to face the barrier portion, and moves back and forth direction together with the laundry in the rotary drum is rotated by the rotation of the rotary drum rotates while being in contact with the packing member, at this time, the laundry Since it hits the substantially annular barrier portion of the packing member, the substantially annular barrier portion is slightly worn, but the packing member is not torn, and it is possible to prevent water leakage due to the breaking of the packing member. Further, the substantially annular barrier portion can prevent the water accumulated in the bulging portion formed on the outer peripheral side from being wetted, and can prevent the laundry in the rotating drum from getting wet.

[0015]
【Example】
An embodiment of the present invention will be described below with reference to FIGS. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0016]
As shown in FIG. 3, the first motor (drive motor) 26 rotates the rotary drum 1 at a first rotational speed N1 (for example, 53 rpm) to perform washing or rinsing. The motor (drive motor) 27 dehydrates the rotary drum 1 by rotating it at a second rotation speed N2 (for example, 1000 rpm). The first motor 26 and the second motor 27 are constituted by induction motors, and are connected to a driven pulley 30 via belts 28 and 29, respectively.
[0017]
The driven pulley 30 has two types of reduction ratios. The first motor 26 is connected to a driven pulley 30a having a large reduction ratio via a belt 28, and the second motor 27 is reduced via a belt 29. It is connected to a driven pulley 30b having a small ratio, and is fixed to the other end of the rotating shaft 4 having one end fixed to the rotation center of the rotating drum 1. The control device 31 controls operations of the heater 17, the first motor 26, the second motor 27, and the like, and sequentially controls a series of processes such as washing, rinsing, and dehydration.
[0018]
The packing member 32 is formed in a substantially cylindrical shape with rubber, and connects the opening 14 of the outer tub 3 corresponding to the front opening 13 of the rotary drum 1 and the body front opening 15. As shown in FIGS. 1 and 2, a substantially annular attachment member 34 is attached to the body side end 33 of the packing member 32, and a screw 35 and a nut 36 are attached to the substantially annular attachment member 34 from the front side of the body 8. The body side end portion 33 of the packing member 32 is sandwiched between the substantially annular mounting member 34 and the inner peripheral surface portion of the body front opening 15.
[0019]
Since the attachment member 34 has a substantially annular shape, the configuration can be simplified. The attachment member 34 is fitted into the packing member 32, and the packing member 32 is sandwiched between the attachment member 34 and the inner peripheral surface of the peripheral front opening 15. Therefore, assembly workability and serviceability can be improved.
[0020]
In addition, the packing member 32 is partially folded back and inward in the length direction to form a bulging portion 37, and the tip of the inward protruding portion has a height greater than the radial thickness A of the packing member 32. A substantially annular barrier portion 38 having a length B is integrally formed, and a rib 39 is provided opposite to the substantially annular barrier portion 38.
[0021]
To explain the operation in the above configuration, the window 16 is opened, the laundry is put into the rotary drum 1, the power switch (not shown) is turned on, and then the start switch (not shown) provided in the control device 31 is turned on. When the operation is started by operating, the water supply valve 40 operates to supply water, and when a predetermined water level is detected by a water level detection means (not shown), the water supply is stopped and the first motor 26 is driven. In the washing process, since the laundry contains water, the revolving drum 1 is rotationally driven by the first motor 26 at the first rotation speed N1 while supplying water, and the laundry in the revolving drum 1 is lifted to the surface of the water. Fall down.
[0022]
At this time, the heater 17 is energized and heated while controlling the washing water in the outer tub 3 at a substantially constant temperature. When the washing process ends, the drain pump 41 operates to drain the washing water in the outer tub 3. Thereafter, in the dewatering process via the rinsing process, the rotary drum 1 is rotationally driven at the second rotational speed N2, and the laundry is dewatered by centrifugation.
[0023]
When the rotating drum 1 is rotated at the first rotation speed N1 in the washing process or the rinsing process, the laundry in the rotating drum 1 rotates and moves in the front-rear direction by the rotation of the rotating drum 1, and contacts the packing member 32. Rotate while. For this reason, the laundry rotates while hitting or getting over the rib 39 of the packing member 32. However, since the laundry hits the substantially annular barrier portion 38, the substantially annular barrier portion 38 is worn slightly, but the packing member 32 is worn. Is prevented from being broken, and it is possible to prevent water leakage due to the breaking of the packing member 32.
[0024]
Further, when the rotating drum 1 is rotated at the second rotation speed N2 in the dehydration process, if the laundry in the rotating drum 1 is in an unbalanced state, the swinging body mainly composed of the outer tub 3 vibrates (swings). The packing member 32 repeats expansion and contraction in a substantially horizontal direction due to expansion and contraction of the bulging portion 37 due to this vibration. At this time, the water accumulated in the bulging portion 37 tends to jump, but the substantially annular barrier portion 38 can prevent the water from jumping up, and the water in the rotating drum 1 is wetted by the jumped water. Can be prevented.
[0025]
In addition, since the substantially annular barrier portion 38 has a radial thickness A smaller than the height dimension B, the packing member 32 repeats expansion and contraction in the substantially horizontal direction by expansion and contraction of the bulging portion 37. An abnormal sound such as an impact sound generated when the barrier portion 38 hits the rib 39 can be reduced.
[0026]
As described above, according to this embodiment, the attachment member 34 that sandwiches the body-side end portion 33 of the substantially cylindrical packing member 32 with the peripheral inner surface portion of the body front opening 15 has a substantially annular shape. 34, the mounting member 34 can be simply fitted into the packing member 32, and the packing member 32 only needs to be sandwiched between the mounting member 34 and the inner peripheral surface of the front opening 15 of the body. Serviceability can be improved.
[0027]
In addition, since the fitting force between the packing member 32 and the inner surface of the window 16 can be adjusted by adjusting the press margin with the packing member 32 by the opening end portion 34a of the mounting member 34, the inner surface of the window 16 and the packing can be adjusted. Water can be prevented from leaking through the gap between the member 32 and the opening / closing force of the window 16 can be adjusted. Moreover, since the substantially annular mounting member 34 and the peripheral edge of the body front opening 15 are fastened and fixed from the front side of the body 8 with screws 35, assembly workability and serviceability can be improved.
[0028]
In this embodiment, the screw 35 and the nut 36 are used to fasten the substantially annular mounting member 34. However, instead of the nut 36, a bar ring is provided on the mounting member 34, and screwing is performed there. Similar effects can be obtained in terms of shape.

【The invention's effect】
As described above, according to the first aspect of the present invention, the rotating drum having the rotating shaft in the substantially horizontal direction, the outer tub enclosing the rotating drum, and the rotating drum rotating during washing and dewatering. A drive motor, a body housing a rocking body mainly composed of the outer tank so as to be able to rock, and an opening of the outer tank corresponding to the front opening of the rotating drum and a front opening of the body. with the a substantially cylindrical packing member, the packing member forms a bulging portion that bulges to the outer peripheral side by Succoth return folding its lengthwise into partial rear and inward, said packing member At the tip of the inward projecting portion folded back inward , the bulging portion is partially covered, and a substantially annular barrier portion having a radial thickness smaller than the height dimension in the rotational axis direction is integrally formed , and Front opening of the rotating drum and the substantially annular shape Since a rib so as to face the barrier portion of the substantially annular between the barrier portion, even if the laundry in the rotary drum by the rotation of the rotary drum is moved in the front-rear direction together with the rotation, the laundry Packing Since it hits the substantially annular barrier portion of the member, the substantially annular barrier portion is somewhat worn, but the packing member is not torn, and it is possible to prevent water leakage due to the breaking of the packing member. Further, the substantially annular barrier portion can prevent the water accumulated in the bulging portion formed on the outer peripheral side from being wetted, and can prevent the laundry in the rotating drum from getting wet. Furthermore, the contact area when the substantially annular barrier portion comes into contact with the rib provided at the position facing the barrier portion can be reduced, and the impact sound generated when the barrier portion hits the rib during operation can be reduced. In addition, it is possible to improve the durability of the mold by securing the thickness of the mold.
