Description

この発明は、洗濯機に関する。   The present invention relates to a washing machine.

下記特許文献１に記載の洗濯機では、機枠の内部において外槽が４本の吊り棒によって支持され、外槽の内部には洗濯脱水槽が回転可能に支持され、洗濯脱水槽の底部には洗濯物を撹拌するためのパルセータが配置される。外槽の下面に取り付けられたモータの回転動力が洗濯脱水槽およびパルセータに伝達される。吊り棒では、下端部が、外槽の底壁より張り出した取付片に固定され、上端部が、機枠から内側に張り出した取付片に固定された吊り棒受け金具によって保持される。吊り棒の先端に設けられた防振体の圧縮コイルばねが伸縮することによって、洗濯運転での脱水工程などにおける外槽の振動が吸収される。   In the washing machine described in Patent Document 1 below, the outer tub is supported by four hanging rods inside the machine frame, the laundry dewatering tub is rotatably supported inside the outer tub, and the bottom of the laundry dewatering tub is Is equipped with a pulsator for stirring the laundry. The rotational power of the motor attached to the lower surface of the outer tub is transmitted to the washing / dehydrating tub and the pulsator. In the suspension bar, the lower end portion is fixed to an attachment piece that protrudes from the bottom wall of the outer tub, and the upper end portion is held by a suspension rod bracket that is fixed to the attachment piece that protrudes inward from the machine frame. When the compression coil spring of the vibration isolator provided at the tip of the suspension rod expands and contracts, the vibration of the outer tub in the dehydration process in the washing operation is absorbed.

特開２００１−１３７５９２号公報JP 2001-137582 A

特許文献１に記載の洗濯機では、脱水工程の停止のために洗濯脱水槽の回転にブレーキがかかると、洗濯脱水槽内における洗濯物の偏りによって外槽が大きく振れるが、４本の吊り棒が外槽の振れを抑えきれないことによって、外槽が洗濯機の筐体に当たってしまう虞がある。   In the washing machine described in Patent Document 1, when a brake is applied to the rotation of the laundry dewatering tank to stop the dewatering process, the outer tub shakes greatly due to the bias of the laundry in the laundry dewatering tank. However, there is a possibility that the outer tub may hit the casing of the washing machine due to the fact that the shake of the outer tub cannot be suppressed.

この発明は、かかる背景のもとでなされたもので、筐体内に配置された洗濯槽が振れて筐体に当たることを抑制できる洗濯機を提供することを目的とする。   The present invention has been made under such a background, and an object of the present invention is to provide a washing machine that can prevent a washing tub disposed in a casing from shaking and hitting the casing.

本発明は、筐体と、洗濯物を収容して回転可能な内槽と、前記内槽を収容する外槽とを有し、前記筐体内に配置される洗濯槽と、前記筐体から吊り下がる棒状に形成され、前記洗濯槽を弾性支持する４つの支持部材と、それぞれの前記支持部材の下部に１つずつ取り付けられ、前記支持部材を前記洗濯槽に連結する受け部と、を含み、全ての前記受け部は、同じ高さ位置に配置され、前記４つの支持部材では、一対の前記支持部材と他の一対の前記支持部材とで長さが異なる、洗濯機である。   The present invention has a housing, a rotatable inner tub that accommodates laundry, and an outer tub that accommodates the inner tub, the laundry tub disposed in the housing, and suspended from the housing Four support members formed elastically to support the washing tub, and one receiving portion that is attached to the lower portion of each of the support members and connects the support member to the washing tub, All the said receiving parts are arrange | positioned in the same height position, and are a washing machine from which a length differs in a pair of said support member and another pair of said support member in said four support members.

また、本発明は、前記洗濯槽は、垂直方向に対して交差するように回動可能であることを特徴とする。   Further, the present invention is characterized in that the washing tub is rotatable so as to intersect with the vertical direction.

本発明によれば、筐体から吊り下がる棒状に形成された４つの支持部材は、それぞれの下部に１つずつ取り付けられた受け部によって洗濯槽に連結されることより、筐体内に配置された洗濯槽を弾性支持する。全ての受け部は、同じ高さ位置に配置され、４つの支持部材では、一対の支持部材と他の一対の支持部材とで長さが異なる。この構成であれば、洗濯運転の脱水工程において洗濯槽の内槽が回転中であっても、脱水工程の停止のために内槽の回転にブレーキがかかったときであっても、４つの支持部材によって洗濯槽の振れが効果的に抑えられる。これにより、洗濯槽が振れて筐体に当たることを抑制できる。   According to the present invention, the four support members formed in a rod shape suspended from the casing are arranged in the casing by being connected to the washing tub by receiving portions attached one by one to each lower portion. Elastically supports the washing tub. All the receiving portions are arranged at the same height position, and the lengths of the four support members are different between the pair of support members and the other pair of support members. With this configuration, even if the inner tub of the washing tub is rotating in the dehydration process of the washing operation, even when the rotation of the inner tub is braked to stop the dehydration process, four supports are provided. The vibration of the washing tub is effectively suppressed by the member. Thereby, it can suppress that a washing tub shakes and contacts a housing | casing.

また、本発明によれば、洗濯槽は、垂直方向に対して交差するように回動可能であってもよく、この構成の洗濯機であっても、４つの支持部材によって洗濯槽の振れが効果的に抑えられるので、洗濯槽が振れて筐体に当たることを抑制できる。   Further, according to the present invention, the washing tub may be rotatable so as to intersect with the vertical direction, and even in the washing machine of this configuration, the washing tub is shaken by the four support members. Since it can suppress effectively, it can control that a washing tub shakes and hits a case.

The ribs 17 include vertical ribs 17 </ b> A extending along the vertical direction Z and horizontal ribs 17 </ b> B extending along the circumferential direction S of the outer tub 3. A receiving portion 18 is provided at the lower end of the two vertical ribs 17A adjacent in the circumferential direction S. There are four receiving portions 18 and are integrally provided at the lower end portion of the outer peripheral surface of the circumferential wall 15 so as to be arranged one by one at the four corners of the housing 1 in plan view. The two receiving portions 18 positioned on the front side Y1 are referred to as a front receiving portion 18A, and the remaining two receiving portions 18 positioned on the rear side Y2 are referred to as a rear receiving portion 18B. The two front receiving portions 18A are arranged farther left and right on the lower side Z2 than the front portion 13A of the upper horizontal strut 13. The two rear receiving portions 18B are arranged apart from each other on the lower side Z2 with respect to the rear portion 13C of the upper horizontal column 13.

それぞれの受け部１８は、隣り合う２つの縦リブ１７Ａ間に架設されて径方向外側Ｒへ膨出するように湾曲した板状のベース部１９と、ベース部１９の上端から上側Ｚ１へ向けて膨出するドーム状に形成された係合部２０とを一体的に含む。隣り合う２つの縦リブ１７Ａの下端部と、これらの縦リブ１７Ａに跨って設けられた受け部１８と、受け部１８の上端の係合部２０と、円周壁１５の外周面とによって囲まれた空間を、収容空間２１という。収容空間２１は、係合部２０へ向けて上側Ｚ１へ窪む凹部であって、ベース部１９の下端から下側Ｚ２へ露出される。受け部１８には、係合部２０の上端部を上下方向Ｚに貫通する貫通穴１８Ｃと、貫通穴１８Ｃから連続して下側Ｚ２に延びて受け部１８全体を周方向Ｓにおいて二分するスリット１８Ｄとが形成される。貫通穴１８Ｃおよびスリット１８Ｄは、収容空間２１に連通した状態にある。   Each receiving portion 18 is constructed between two adjacent vertical ribs 17A and is curved so as to bulge outward in the radial direction R. From the upper end of the base portion 19 to the upper side Z1 It integrally includes an engaging portion 20 formed in a dome shape that bulges. Surrounded by the lower ends of two adjacent vertical ribs 17A, the receiving portion 18 provided straddling these vertical ribs 17A, the engaging portion 20 at the upper end of the receiving portion 18, and the outer peripheral surface of the circumferential wall 15. This space is referred to as a housing space 21. The accommodation space 21 is a recess that is recessed toward the upper side Z <b> 1 toward the engaging portion 20, and is exposed from the lower end of the base portion 19 to the lower side Z <b> 2. The receiving portion 18 includes a through hole 18C that penetrates the upper end portion of the engaging portion 20 in the vertical direction Z, and a slit that extends continuously from the through hole 18C to the lower side Z2 and bisects the entire receiving portion 18 in the circumferential direction S. 18D is formed. The through hole 18 </ b> C and the slit 18 </ b> D are in communication with the accommodation space 21.

底壁１６の下面には、下側Ｚ２へ張り出して底壁１６を補強する複数のリブ２２や、外槽３に溜まった水を機外へ排出するための排水路２３などが設けられる。   On the lower surface of the bottom wall 16, there are provided a plurality of ribs 22 that project to the lower side Z <b> 2 and reinforce the bottom wall 16, drainage channels 23 for discharging water accumulated in the outer tub 3 to the outside of the machine, and the like.

図１において２点鎖線で示された内槽４は、たとえば金属製であり、外槽３よりも一回り小さい有底円筒状に形成され、外槽３内に同軸状で収容される。内槽４は、内部に洗濯物を収容することができる。内槽４の上面には、外槽３の開口１５Ａに対して真下から連通する開口４Ａが形成される。洗濯機１００の使用者は、化粧カバー１１における前述した出入口（図示せず）と開口１５Ａと開口４Ａとを介して、内槽４に対して洗濯物を出し入れする。内槽４には、図示しない貫通孔が複数形成され、外槽３内の水は、当該貫通孔を介して、外槽３と内槽４との間で行き来できる。そのため、外槽３内の水位と内槽４内の水位とは一致する。内槽４の底壁において内槽４の円中心と一致する部分には、下側Ｚ２へ突出する回転軸４Ｂが設けられる。回転軸４Ｂは、外槽３の底壁１６によって回転可能に支持される。そのため、内槽４は、回転軸４Ｂまわりに回転可能である。   The inner tank 4 indicated by a two-dot chain line in FIG. 1 is made of, for example, metal, is formed in a bottomed cylindrical shape that is slightly smaller than the outer tank 3, and is accommodated coaxially in the outer tank 3. The inner tub 4 can store laundry therein. On the upper surface of the inner tank 4, an opening 4 </ b> A that communicates with the opening 15 </ b> A of the outer tank 3 from directly below is formed. The user of the washing machine 100 puts laundry into and out of the inner tub 4 through the aforementioned entrance / exit (not shown), the opening 15A, and the opening 4A in the decorative cover 11. A plurality of through holes (not shown) are formed in the inner tank 4, and water in the outer tank 3 can go back and forth between the outer tank 3 and the inner tank 4 through the through holes. Therefore, the water level in the outer tub 3 matches the water level in the inner tub 4. A rotating shaft 4 </ b> B projecting to the lower side Z <b> 2 is provided at a portion of the bottom wall of the inner tank 4 that coincides with the circle center of the inner tank 4. The rotating shaft 4B is rotatably supported by the bottom wall 16 of the outer tub 3. Therefore, the inner tank 4 can rotate around the rotation shaft 4B.

モータ５は、インバータモータなどの電動モータである。モータ５は、外槽３の底壁１６に対して下側Ｚ２から固定される。モータ５は、上側Ｚ１へ突出する出力軸（図示せず）を有する。伝達機構６は、モータ５の出力軸と内槽４の回転軸４Ｂとの間に介在される。伝達機構６として、公知のものが用いられる。伝達機構６は、モータ５が出力軸から出力する駆動力を回転軸４Ｂに伝達する。これにより、内槽４が回転する。特に、脱水工程では、洗濯物に遠心力を作用させて効果的に脱水を行うために、内槽４が高速回転する。なお、内槽４内には、収容された洗濯物を撹拌するために回転するパルセータ（図示せず）が設けられ、モータ５の駆動力が伝達機構６からパルセータに伝達されてもよい。   The motor 5 is an electric motor such as an inverter motor. The motor 5 is fixed to the bottom wall 16 of the outer tub 3 from the lower side Z2. The motor 5 has an output shaft (not shown) protruding to the upper side Z1. The transmission mechanism 6 is interposed between the output shaft of the motor 5 and the rotating shaft 4B of the inner tank 4. A known mechanism is used as the transmission mechanism 6. The transmission mechanism 6 transmits the driving force output from the output shaft of the motor 5 to the rotating shaft 4B. Thereby, the inner tank 4 rotates. In particular, in the dehydration step, the inner tub 4 rotates at high speed in order to effectively perform dehydration by applying centrifugal force to the laundry. In the inner tub 4, a pulsator (not shown) that rotates to stir the stored laundry may be provided, and the driving force of the motor 5 may be transmitted from the transmission mechanism 6 to the pulsator.

支持部材７は、棒状に形成された部材であって吊り棒とも呼ばれ、上下に長手になった状態で筐体１内に配置される。支持部材７は、４つ存在し、筐体１の四隅に１つずつ配置される。４つの支持部材７のうち、前側Ｙ１に位置する左右一対の支持部材７を前側支持部材７Ａといい、後側Ｙ２に位置する他の左右一対の支持部材７を後側支持部材７Ｂという。図１ならびに後述する図３および図６では、左側Ｘ１に位置する前側支持部材７Ａおよび後側支持部材７Ｂが１つずつ図示されて、右側Ｘ２に位置する前側支持部材７Ａおよび後側支持部材７Ｂは図示されない。しかし、左右一対の前側支持部材７Ａは、左右方向Ｘから見て重なる位置にあり、左右一対の後側支持部材７Ｂは、左右方向Ｘから見て重なる位置にある。   The support member 7 is a member formed in a rod shape and is also called a hanging rod, and is arranged in the housing 1 in a state of being vertically long. There are four support members 7, and one support member 7 is arranged at each of the four corners of the housing 1. Of the four support members 7, a pair of left and right support members 7 positioned on the front side Y1 is referred to as a front side support member 7A, and another pair of left and right support members 7 positioned on the rear side Y2 is referred to as a rear side support member 7B. 1 and FIGS. 3 and 6 to be described later, a front support member 7A and a rear support member 7B located on the left side X1 are shown one by one, and a front support member 7A and a rear side support member 7B located on the right side X2 are shown. Is not shown. However, the pair of left and right front support members 7 </ b> A are in positions that overlap when viewed from the left and right direction X, and the pair of left and right rear support members 7 </ b> B are at positions that overlap when viewed from the left and right direction X.

支持部材７の一例として、摩擦ダンパが挙げられる。もちろん、支持部材７として、油圧ダンパなどの他の公知のダンパを用いることができる。摩擦ダンパである場合の支持部材７は、上下に細長く直線状に延びるロッド２８と、ロッド２８の下端部を収容する中空のケース２９とを含む。支持部材７の要部およびその周辺部分の模式的な縦断面図である図２を参照して、支持部材７は、ケース２９内でロッド２８の下端部に連結された円盤状のダンパ部材３０と、ケース２９内に配置されるコイルばねなどの付勢部材３１とを含む。ロッド２８がケース２９に対して相対移動可能であり、この相対移動により、支持部材７全体が伸縮可能である。また、ケース２９内で付勢部材３１がダンパ部材３０を下側Ｚ２へ付勢するので、支持部材７全体は弾性的に伸縮可能である。   An example of the support member 7 is a friction damper. Of course, other known dampers such as a hydraulic damper can be used as the support member 7. The support member 7 in the case of a friction damper includes a rod 28 that is elongated vertically and extends linearly, and a hollow case 29 that houses the lower end of the rod 28. Referring to FIG. 2, which is a schematic longitudinal sectional view of the main part of support member 7 and its peripheral part, support member 7 is a disk-shaped damper member 30 connected to the lower end of rod 28 in case 29. And a biasing member 31 such as a coil spring disposed in the case 29. The rod 28 can move relative to the case 29, and the entire support member 7 can be expanded and contracted by this relative movement. Further, since the urging member 31 urges the damper member 30 to the lower side Z2 in the case 29, the entire support member 7 can be elastically expanded and contracted.

洗濯機１００の要部の模式的な左側面図である図３を参照して、ロッド２８に関連し、外枠１０の左右一対の上側横支柱１３のそれぞれでは、前側部分１３Ａおよび後側部分１３Ｃのそれぞれに、連結部３２が１つずつ設けられる（図１も参照）。つまり、連結部３２は、合計で４つ存在する。それぞれの連結部３２は、上下方向Ｚに薄い金属製の板状に形成される。連結部３２は、上側横支柱１３に対して一体的に設けられてもよいし、別部品として上側横支柱１３に対してボルトなどで固定されてもよい。左側Ｘ１の上側横支柱１３に設けられた連結部３２は、この上側横支柱１３から洗濯槽２へ向けて右側Ｘ２へ張り出して配置される。右側Ｘ２の上側横支柱１３に設けられた連結部３２（図示せず）は、この上側横支柱１３から洗濯槽２へ向けて左側Ｘ１へ張り出して配置される。それぞれの上側横支柱１３において、前側部分１３Ａに設けられた連結部３２を前側連結部３２Ａといい、後側部分１３Ｃに設けられた連結部３２を後側連結部３２Ｂという（図１も参照）。それぞれの連結部３２には、連結部３２を上下方向Ｚに貫通する貫通穴３２Ｃが形成される。連結部３２において貫通穴３２Ｃを区画する内周面３２Ｄは、下側Ｚ２へ向かうにつれて狭くなる球状に形成される。   Referring to FIG. 3, which is a schematic left side view of the main part of washing machine 100, a front side portion 13 </ b> A and a rear side portion are associated with rod 28 and each of a pair of left and right upper horizontal struts 13 of outer frame 10. Each of 13C is provided with one connecting portion 32 (see also FIG. 1). That is, there are a total of four connecting portions 32. Each connecting portion 32 is formed in a thin metal plate shape in the vertical direction Z. The connecting portion 32 may be provided integrally with the upper horizontal column 13 or may be fixed to the upper horizontal column 13 with a bolt or the like as a separate part. The connecting portion 32 provided on the upper horizontal strut 13 on the left side X1 is disposed so as to protrude from the upper lateral strut 13 toward the right side X2 toward the washing tub 2. A connecting portion 32 (not shown) provided on the upper horizontal strut 13 on the right side X2 is disposed so as to protrude from the upper lateral strut 13 toward the washing tub 2 toward the left side X1. In each of the upper horizontal struts 13, the connecting portion 32 provided in the front portion 13A is referred to as a front connecting portion 32A, and the connecting portion 32 provided in the rear portion 13C is referred to as a rear connecting portion 32B (see also FIG. 1). . Each connecting portion 32 is formed with a through hole 32 </ b> C penetrating the connecting portion 32 in the vertical direction Z. An inner peripheral surface 32D that defines the through hole 32C in the connecting portion 32 is formed in a spherical shape that becomes narrower toward the lower side Z2.

ロッド２８の上端部には、下側Ｚ２へ向けて膨出する半球状の上側係合部２８Ａが設けられる。それぞれの前側支持部材７Ａの上側係合部２８Ａは、左右方向Ｘで同じ位置にある前側連結部３２Ａの貫通穴３２Ｃに対して上側Ｚ１から嵌め込まれ、これにより、前側連結部３２Ａに上側Ｚ１から係合した状態にある。それぞれの後側支持部材７Ｂの上側係合部２８Ａは、左右方向Ｘで同じ位置にある後側連結部３２Ｂの貫通穴３２Ｃに対して上側Ｚ１から嵌め込まれ、これにより、後側連結部３２Ｂに上側Ｚ１から係合した状態にある。それぞれの上側係合部２８Ａは、連結部３２において貫通穴３２Ｃを区画する内周面３２Ｄに球面接触した状態にある。   The upper end portion of the rod 28 is provided with a hemispherical upper engagement portion 28A that bulges toward the lower side Z2. The upper engaging portions 28A of the respective front support members 7A are fitted from the upper side Z1 into the through holes 32C of the front side connecting portion 32A located at the same position in the left-right direction X, whereby the front side connecting portion 32A is inserted into the front side connecting portion 32A from the upper side Z1. In an engaged state. The upper engagement portions 28A of the respective rear support members 7B are fitted from the upper side Z1 into the through holes 32C of the rear connection portions 32B that are in the same position in the left-right direction X, whereby the rear connection portions 32B are fitted into the rear connection portions 32B. The state is engaged from the upper side Z1. Each upper engaging portion 28A is in spherical contact with the inner peripheral surface 32D that defines the through hole 32C in the connecting portion 32.

ケース２９は、ロッド２８の長手方向において長手となった略円筒状に形成される。ケース２９の上端部は、下側係合部２９Ａとして、上側Ｚ１へ向けて膨出する半球状に形成される。ロッド２８は、下側係合部２９Ａの上端２９Ｂを上下に貫通して上側Ｚ１へ突出した状態にある。それぞれの前側支持部材７Ａの下側係合部２９Ａは、左右方向Ｘで同じ位置にある前側受け部１８Ａにおける収容空間２１に対して下側Ｚ２から嵌め込まれ、これにより、この前側受け部１８Ａの係合部２０に下側Ｚ２から係合した状態にある。それぞれの後側支持部材７Ｂの下側係合部２９Ａは、左右方向Ｘで同じ位置にある後側受け部１８Ｂにおける収容空間２１に対して下側Ｚ２から嵌め込まれ、これにより、この後側受け部１８Ｂの係合部２０に下側Ｚ２から係合した状態にある。このように、４つの受け部１８は、それぞれの支持部材７の下部にある下側係合部２９Ａに１つずつ取り付けられる。なお、下側係合部２９Ａを収容空間２１に嵌め込む際に、ロッド２８が受け部１８のスリット１８Ｄを通る。   The case 29 is formed in a substantially cylindrical shape that is long in the longitudinal direction of the rod 28. The upper end portion of the case 29 is formed as a lower engagement portion 29A in a hemispherical shape that bulges toward the upper side Z1. The rod 28 is in a state where it penetrates the upper end 29B of the lower engagement portion 29A vertically and projects to the upper side Z1. The lower engagement portions 29A of the respective front support members 7A are fitted from the lower side Z2 into the accommodation space 21 in the front reception portion 18A located at the same position in the left-right direction X, whereby the front reception portion 18A The engagement portion 20 is engaged from the lower side Z2. The lower engagement portions 29A of the respective rear support members 7B are fitted from the lower side Z2 into the accommodating spaces 21 in the rear receiving portions 18B located at the same position in the left-right direction X. The engagement portion 20 of the portion 18B is engaged from the lower side Z2. In this way, the four receiving portions 18 are attached to the lower engaging portions 29A at the lower portions of the respective supporting members 7 one by one. The rod 28 passes through the slit 18 </ b> D of the receiving portion 18 when the lower engagement portion 29 </ b> A is fitted into the accommodation space 21.

それぞれの支持部材７において、下側係合部２９Ａは、係合部２０において収容空間２１を区画する内周面２０Ａ（図２参照）に球面接触した状態にあり、ロッド２８は、受け部１８の上端部における貫通穴１８Ｃから上側Ｚ１へ突出した状態にある。ロッド２８は、上下方向Ｚに沿って垂直に延びた姿勢で配置されてもよいが、上下方向Ｚに対して左右方向Ｘや前後方向Ｙへ傾斜した姿勢で配置されてもよい。この実施形態では、前側支持部材７Ａのロッド２８は、上側Ｚ１へ向かうにつれて前側Ｙ１へずれるように傾斜して配置され、後側支持部材７Ｂのロッド２８は、上側Ｚ１へ向かうにつれて後側Ｙ２へずれるように傾斜して配置される。   In each support member 7, the lower engagement portion 29 </ b> A is in spherical contact with the inner peripheral surface 20 </ b> A (see FIG. 2) that defines the accommodation space 21 in the engagement portion 20, and the rod 28 is in the receiving portion 18. It is in the state which protruded from the through-hole 18C in the upper end part to upper side Z1. The rod 28 may be arranged in a posture extending vertically along the vertical direction Z, but may be arranged in a posture inclined in the left-right direction X or the front-back direction Y with respect to the vertical direction Z. In this embodiment, the rod 28 of the front support member 7A is disposed so as to be inclined toward the front side Y1 toward the upper side Z1, and the rod 28 of the rear side support member 7B is moved to the rear side Y2 toward the upper side Z1. It is arranged to be inclined so as to be displaced.

それぞれの支持部材７は、外枠１０の上側横支柱１３に設けられた連結部３２から吊り下がった状態にある（図１も参照）。支持部材７の下端部に位置するケース２９の下側係合部２９Ａが、受け部１８によって洗濯槽２の外槽３に連結される。それぞれの支持部材７が弾性的に伸縮可能であるので、４つ支持部材７は、洗濯槽２と、外槽３に固定されたモータ５および伝達機構６とを吊り下げて弾性支持した状態にある（図１も参照）。そのため、洗濯運転中において内槽４の回転に伴って洗濯槽２に生じた振動が連結部３２を介して筐体１に伝わることが抑制される。   Each support member 7 is in a state of being hung from a connecting portion 32 provided on the upper horizontal column 13 of the outer frame 10 (see also FIG. 1). A lower engagement portion 29 </ b> A of the case 29 located at the lower end portion of the support member 7 is connected to the outer tub 3 of the washing tub 2 by the receiving portion 18. Since each support member 7 can elastically expand and contract, the four support members 7 are in a state where they are elastically supported by suspending the washing tub 2 and the motor 5 and the transmission mechanism 6 fixed to the outer tub 3. Yes (see also FIG. 1). Therefore, the vibration generated in the washing tub 2 with the rotation of the inner tub 4 during the washing operation is suppressed from being transmitted to the housing 1 through the connecting portion 32.

また、それぞれの支持部材７では、ダンパ部材３０が、支持部材７の伸縮の際にロッド２８の下端部とともに移動し、その際にケース２９の内周面２９Ｃ（図２参照）に摺擦するので、ダンパ部材３０とケース２９の内周面２９Ｃとの間に摩擦力が発生する。この摩擦力によって、洗濯槽２に生じた振動が減衰される。それぞれの支持部材７では、前述したように上側係合部２８Ａが連結部３２に球面接触して下側係合部２９Ａが受け部１８の係合部２０に球面接触した状態にあるので、支持部材７は、洗濯槽２の振動による無理な力が支持部材７自身や筐体１に作用しないように、上下方向Ｚに対する傾きを自在に変えることができる。   Further, in each support member 7, the damper member 30 moves together with the lower end portion of the rod 28 when the support member 7 expands and contracts, and at that time, the damper member 30 rubs against the inner peripheral surface 29 </ b> C (see FIG. 2) of the case 29. Therefore, a frictional force is generated between the damper member 30 and the inner peripheral surface 29C of the case 29. The vibration generated in the washing tub 2 is attenuated by this frictional force. In each support member 7, as described above, the upper engagement portion 28 </ b> A is in spherical contact with the coupling portion 32 and the lower engagement portion 29 </ b> A is in spherical contact with the engagement portion 20 of the receiving portion 18. The member 7 can freely change the inclination with respect to the vertical direction Z so that an excessive force due to vibration of the washing tub 2 does not act on the support member 7 itself or the housing 1.

４つの受け部１８は、全て同じ高さ位置に配置され、特に、４つの受け部１８のそれぞれの貫通穴１８Ｃは、上下方向Ｚにおいて同じ位置にある。そのため、４つの支持部材７において受け部１８の収容空間２１に対して下側Ｚ２から嵌め込まれるケース２９は、上下方向Ｚにおいて同じ位置に配置される。詳しくは、４つの支持部材７のケース２９の下側係合部２９Ａにおいて貫通穴１８Ｃから露出される上端２９Ｂは、上下方向Ｚにおいて同じ位置に配置される。   The four receiving portions 18 are all arranged at the same height position. In particular, the through holes 18C of the four receiving portions 18 are at the same position in the vertical direction Z. Therefore, the case 29 fitted from the lower side Z2 with respect to the accommodation space 21 of the receiving portion 18 in the four support members 7 is disposed at the same position in the vertical direction Z. Specifically, the upper ends 29 </ b> B exposed from the through holes 18 </ b> C in the lower engagement portions 29 </ b> A of the cases 29 of the four support members 7 are arranged at the same position in the vertical direction Z.

一方、筐体１の上側横支柱１３において支持部材７の上側係合部２８Ａが係合される４つの連結部３２では、前側部分１３Ａに設けられた前側連結部３２Ａは、前側部分１３Ａよりも高い位置にある後側部分１３Ｃに設けられた後側連結部３２Ｂよりも低い位置にある（図１も参照）。この場合、４つの支持部材７では、前側連結部３２Ａに係合する上側係合部２８Ａを有する一対の前側支持部材７Ａ同士では長さが同じであり、後側連結部３２Ｂに係合する上側係合部２８Ａを有する他の一対の後側支持部材７Ｂでは長さが同じである。しかし、一対の前側支持部材７Ａと一対の後側支持部材７Ｂとで長さが異なり、厳密には、前側支持部材７Ａは、後側支持部材７Ｂよりも短い。なお、ここでの支持部材７の長さとは、一例では、洗濯機１００の運転が停止した状態で、上側係合部２８Ａにおいて連結部３２の下面と一致する部分２８Ｂと、下側係合部２９Ａの上端２９Ｂとを結んでロッド２８に沿って延びる線分Ｌの長さである。線分Ｌの長さは、それぞれの支持部材７において受け部１８から連結部３２までの範囲における部分、つまり、支持部材７において振動の減衰に積極的に寄与する部分の長さでもある。もちろん、別の例として、ロッド２８の全長や支持部材７の全長を、支持部材７の長さと定義してもよい。   On the other hand, in the four connecting portions 32 with which the upper engaging portion 28A of the support member 7 is engaged in the upper lateral strut 13 of the housing 1, the front connecting portion 32A provided in the front portion 13A is more than the front portion 13A. It exists in the position lower than the rear side connection part 32B provided in the rear side part 13C in a high position (refer also FIG. 1). In this case, in the four support members 7, the pair of front support members 7 </ b> A having the upper engagement portions 28 </ b> A that engage with the front connection portions 32 </ b> A have the same length, and the upper sides that engage with the rear connection portions 32 </ b> B. The other pair of rear support members 7B having the engaging portions 28A have the same length. However, the pair of front support members 7A and the pair of rear support members 7B have different lengths. Strictly speaking, the front support member 7A is shorter than the rear support member 7B. Here, the length of the support member 7 is, for example, the portion 28B that coincides with the lower surface of the connecting portion 32 in the upper engaging portion 28A and the lower engaging portion when the operation of the washing machine 100 is stopped. This is the length of the line segment L connecting the upper end 29B of 29A and extending along the rod 28. The length of the line segment L is also the length of each support member 7 in the range from the receiving portion 18 to the coupling portion 32, that is, the length of the portion that positively contributes to vibration damping in the support member 7. Of course, as another example, the total length of the rod 28 and the total length of the support member 7 may be defined as the length of the support member 7.

図４は、脱水工程中の洗濯槽２において内槽４の回転に伴って外槽３に生じる振動の振幅と、前側支持部材７Ａおよび後側支持部材７Ｂの長さの差との関係を示すグラフである。図５は、脱水工程終了による内槽４の回転停止に伴って外槽３に生じる振動の振幅と、前側支持部材７Ａおよび後側支持部材７Ｂの長さの差との関係を示すグラフである。図４および図５のいずれにおいても、横軸は、前側支持部材７Ａが後側支持部材７Ｂよりも短くなる場合における前側支持部材７Ａと後側支持部材７Ｂとの長さの差を示す。一方、図４の縦軸は、脱水工程での内槽４の回転中において外槽３に生じる振動の振幅を示し、図５の縦軸は、脱水工程の終了に伴ってブレーキがかかることによって内槽４の回転が停止したときに外槽３に生じた振動の振幅を示す。長さの差および振幅の単位は、たとえばｍｍである。   FIG. 4 shows the relationship between the amplitude of vibration generated in the outer tub 3 as the inner tub 4 rotates in the washing tub 2 during the dehydration process and the difference in length between the front support member 7A and the rear support member 7B. It is a graph. FIG. 5 is a graph showing the relationship between the amplitude of vibration generated in the outer tub 3 when the rotation of the inner tub 4 is stopped due to the completion of the dehydration process and the difference in length between the front support member 7A and the rear support member 7B. . 4 and 5, the horizontal axis indicates the difference in length between the front support member 7A and the rear support member 7B when the front support member 7A is shorter than the rear support member 7B. On the other hand, the vertical axis in FIG. 4 shows the amplitude of vibration generated in the outer tub 3 during the rotation of the inner tub 4 in the dehydration process, and the vertical axis in FIG. 5 indicates that the brake is applied as the dehydration process ends. The amplitude of the vibration generated in the outer tub 3 when the rotation of the inner tub 4 is stopped is shown. The unit of length difference and amplitude is, for example, mm.

内槽４の回転に対するブレーキとして、洗濯機１００に設けられた制御部（図示せず）がデューティ比を制御してモータ５の回転を急停止させてもよいし、ブレーキ装置（図示せず）を別途設けて制御部がブレーキ装置を作動させることによってモータ５の回転を急停止させてもよい。   As a brake against the rotation of the inner tub 4, a controller (not shown) provided in the washing machine 100 may control the duty ratio to suddenly stop the rotation of the motor 5, or a brake device (not shown). May be provided separately, and the rotation of the motor 5 may be suddenly stopped by operating the brake device by the control unit.

支持部材７の下端部を受ける４つの受け部１８の全てが同じ高さ位置に配置される構成であれば、図４に示すように、前側支持部材７Ａと後側支持部材７Ｂとの長さの差が大きくなっても、脱水工程での内槽４の回転中における外槽３の振動の振幅はほとんど変化しない。一方、図５に示すように、前側支持部材７Ａと後側支持部材７Ｂとの長さの差が大きくなると、ブレーキによる内槽４の回転停止に伴って外槽３に生じる振動の振幅は小さくなる。つまり、前側支持部材７Ａと後側支持部材７Ｂとの長さの差によって、内槽４の回転停止による外槽３の振動が効果的に減衰されるものと思われる。   If all of the four receiving portions 18 that receive the lower end portion of the support member 7 are arranged at the same height position, the lengths of the front support member 7A and the rear support member 7B as shown in FIG. Even if the difference between the two increases, the amplitude of the vibration of the outer tub 3 during the rotation of the inner tub 4 in the dehydration process hardly changes. On the other hand, as shown in FIG. 5, when the difference in length between the front support member 7A and the rear support member 7B increases, the amplitude of vibration generated in the outer tank 3 with the stop of the rotation of the inner tank 4 by the brake decreases. Become. That is, it is considered that the vibration of the outer tub 3 due to the rotation stop of the inner tub 4 is effectively attenuated by the difference in length between the front support member 7A and the rear support member 7B.

よって、一対の前側支持部材７Ａと他の一対の後側支持部材７Ｂとで長さが異なり、４つの受け部１８の全てが同じ高さ位置に配置される構成であれば、脱水工程において内槽４が回転中であっても、脱水工程の停止のために内槽４の回転にブレーキがかかったときであっても、４つの支持部材７によって外槽３の振れが効果的に抑えられる。これにより、筐体１内の洗濯槽２の外槽３が振れて筐体１に当たることを抑制できる。   Therefore, if the length is different between the pair of front support members 7A and the other pair of rear support members 7B, all the four receiving portions 18 are arranged at the same height position. Even if the tank 4 is rotating or even when the rotation of the inner tank 4 is braked to stop the dehydration process, the four support members 7 can effectively suppress the shake of the outer tank 3. . Thereby, it can suppress that the outer tub 3 of the washing tub 2 in the housing | casing 1 shakes and contacts the housing | casing 1. FIG.

図６は、変形例に係る洗濯機１００の左側面図である。図６において、図１〜図３で説明した部分と同一の部分には同一番号を付して、当該部分についての説明は省略する。図１〜図３で説明した洗濯機１００では、洗濯槽２が常に縦置きに配置されるが、図６に示す変形例に係る洗濯機１００では、洗濯槽２の姿勢を変えることができる。   FIG. 6 is a left side view of the washing machine 100 according to the modification. In FIG. 6, the same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the parts is omitted. In the washing machine 100 described with reference to FIGS. 1 to 3, the washing tub 2 is always arranged vertically, but in the washing machine 100 according to the modification shown in FIG. 6, the posture of the washing tub 2 can be changed.

具体的には、変形例に係る洗濯機１００は、支持フレーム５０と、回動部５１と、ロック解除機構５２と、駆動機構５３とをさらに含む。   Specifically, the washing machine 100 according to the modification further includes a support frame 50, a rotation unit 51, a lock release mechanism 52, and a drive mechanism 53.

支持フレーム５０は、左右一対の側板５４と、これらの側板５４間に架設された架設部材（図示せず）とを含む。図６では、左側Ｘ１の側板５４だけが図示される。それぞれの側板５４は、左右方向Ｘから見て略矩形状に形成され、左右方向Ｘに薄い。一対の側板５４の間に、洗濯槽２が配置される。   The support frame 50 includes a pair of left and right side plates 54 and an erection member (not shown) provided between the side plates 54. In FIG. 6, only the left side X1 side plate 54 is shown. Each side plate 54 is formed in a substantially rectangular shape when viewed from the left-right direction X and is thin in the left-right direction X. The washing tub 2 is arranged between the pair of side plates 54.

洗濯槽２の外槽３における左右の側面において左右方向Ｘから見て同じ位置には、左右方向Ｘにおける外側へ突出した金属製の回動軸５５が１つずつ設けられる。外槽３において左側Ｘ１に突出した回動軸５５が、左側Ｘ１の側板５４を貫通し、軸受（図示せず）を介して左側Ｘ１の側板５４によって回動可能に支持される。外槽３において右側Ｘ２に突出した回動軸５５（図示せず）が、右側Ｘ２の側板５４を貫通し、軸受（図示せず）を介して右側Ｘ２の側板５４によって回動可能に支持される。これにより、外槽３および内槽４（図示せず）を有する洗濯槽２は、支持フレーム５０によって支持され、上下方向Ｚに対して交差するように回動軸５５まわりに回動可能である。具体的には、洗濯槽２の回動に伴って、外槽３および内槽４の中心軸Ｊが、上下方向Ｚに対して前後方向Ｙへ傾斜する。洗濯槽２の回動方向を回動方向Ｋという。   At the same position on the left and right side surfaces of the outer tub 3 of the washing tub 2 as viewed from the left-right direction X, one metal rotation shaft 55 protruding outward in the left-right direction X is provided. A rotation shaft 55 protruding to the left side X1 in the outer tub 3 penetrates the left side X1 side plate 54 and is rotatably supported by the left side X1 side plate 54 via a bearing (not shown). A rotation shaft 55 (not shown) protruding to the right side X2 in the outer tub 3 passes through the side plate 54 of the right side X2, and is rotatably supported by the side plate 54 of the right side X2 via a bearing (not shown). The Thereby, the washing tub 2 having the outer tub 3 and the inner tub 4 (not shown) is supported by the support frame 50 and can be rotated around the rotation shaft 55 so as to intersect the vertical direction Z. . Specifically, as the washing tub 2 rotates, the center axis J of the outer tub 3 and the inner tub 4 is inclined in the front-rear direction Y with respect to the vertical direction Z. The rotation direction of the washing tub 2 is referred to as a rotation direction K.

When the actuator of the main body portion 56 is operated, the lock portion 57 slides between the advanced position that has advanced to the rear side Y2 and the retracted position that has retracted to the front side Y1. The lock portion 57 in FIG. 6 is in the advanced position, and is in a state of being fitted into the concave portion 51C at the same position in the rotation direction K. Thereby, rotation of the rotation part 51 and the washing tub 2 is locked. In this state, when the lock part 57 is retracted to the retracted position, the lock part 57 is disengaged from the recess 51C, so that the rotation part 51 and the washing tub 2 are unlocked.

駆動機構５３は、フレーム５８と、一対の支持部５９と、ねじ軸６０と、モータ６１と、カップリング６２と、ナット部材６３と、センサ６４とを含む。   The drive mechanism 53 includes a frame 58, a pair of support portions 59, a screw shaft 60, a motor 61, a coupling 62, a nut member 63, and a sensor 64.

フレーム５８は、金属板をたとえばクランク状に折り曲げることよって形成され、左側Ｘ１の側板５４の開口５４Ａを右側Ｘ２から覆うように当該側板５４に対して右側Ｘ２から固定される。一対の支持部５９は、前後方向Ｙに離れて並んだ状態でフレーム５８に固定され、フレーム５８から左側Ｘ１へ突出した状態にある。ねじ軸６０は、前後方向Ｙに沿って細長く延びる円柱状に形成され、その外周面のほぼ全域には、螺旋状に延びるねじ山６０Ａが形成される。ねじ軸６０は、前後一対の支持部５９に設けられた軸受（図示せず）によって、回転可能に両持ち支持される。   The frame 58 is formed by bending a metal plate, for example, in a crank shape, and is fixed from the right side X2 to the side plate 54 so as to cover the opening 54A of the left side X1 side plate 54 from the right side X2. The pair of support portions 59 are fixed to the frame 58 in a state where they are arranged apart from each other in the front-rear direction Y, and project from the frame 58 to the left side X1. The screw shaft 60 is formed in a cylindrical shape extending in the longitudinal direction Y, and a screw thread 60 </ b> A extending in a spiral shape is formed in almost the entire outer peripheral surface of the screw shaft 60. The screw shaft 60 is rotatably supported by bearings (not shown) provided on the pair of front and rear support portions 59.

モータ６１は、一般的な電動のモータであり、後側Ｙ２へ突出してねじ軸６０と同軸状に配置される出力軸６５を有する。ねじ軸６０の前端部と出力軸６５とは、カップリング６２によって一体回転可能に連結される。そのため、モータ６１が駆動されて出力軸６５が回転すると、ねじ軸６０は、出力軸６５と一体回転する。ナット部材６３は、螺旋状に延びるねじ山（図示せず）が内周面に形成された環状のナットを有し、このねじ山とねじ軸６０のねじ山６０Ａとが互いに螺合するように、ねじ軸６０に対して外嵌される。モータ６１の駆動に応じてねじ軸６０が回転すると、ねじ軸６０の回転に伴って、ナット部材６３全体が、ねじ軸６０の軸方向である前後方向Ｙに沿って移動する。ナット部材６３は、回動部５１の延設部５１Ｄに挿入された連結ピン６６が固定されることによって、連結ピン６６を介して、回動部５１に連結される。そのため、ねじ軸６０の回転に伴ってナット部材６３が前後方向Ｙに沿って移動すると、回動部５１が、ナット部材６３によって前後方向Ｙに引っ張られることにより、洗濯槽２を伴って回動する。   The motor 61 is a general electric motor, and has an output shaft 65 that protrudes toward the rear side Y2 and is arranged coaxially with the screw shaft 60. The front end portion of the screw shaft 60 and the output shaft 65 are coupled by a coupling 62 so as to be integrally rotatable. Therefore, when the motor 61 is driven and the output shaft 65 rotates, the screw shaft 60 rotates integrally with the output shaft 65. The nut member 63 has an annular nut in which a spirally extending thread (not shown) is formed on the inner peripheral surface, and the thread and the thread 60A of the screw shaft 60 are screwed together. The screw shaft 60 is externally fitted. When the screw shaft 60 rotates in accordance with the drive of the motor 61, the nut member 63 as a whole moves along the front-rear direction Y, which is the axial direction of the screw shaft 60, as the screw shaft 60 rotates. The nut member 63 is connected to the rotating portion 51 via the connecting pin 66 by fixing the connecting pin 66 inserted into the extending portion 51 </ b> D of the rotating portion 51. Therefore, when the nut member 63 moves along the front-rear direction Y along with the rotation of the screw shaft 60, the rotation part 51 rotates along with the washing tub 2 by being pulled in the front-rear direction Y by the nut member 63. To do.

センサ６４は、前後方向Ｙにおけるナット部材６３の位置から洗濯槽２の回動角度θを検出するためのセンサであり、センサ６４として、フォトセンサなどの光学センサを用いることができる。この場合、センサ６４は、回動部５１における凹部５１Ｃと同数設けられ、前後方向Ｙに並んだ状態でフレーム５８に固定される。それぞれのセンサ６４には、センサ６４を前後方向Ｙに貫通する溝６４Ａが形成され、センサ６４では、検知光が溝６４Ａを上下方向Ｚに横切った状態にある。ナット部材６３には、ドグと呼ばれるレバー状の被検知部６３Ａが設けられる。回動角度θが５度、１５度、３０度、４５度、６０度のいずれかであるとき、被検知部６３Ａは、いずれか１つのセンサ６４の溝６４Ａに嵌まって当該溝６４Ａにおける検知光を遮る。そのため、５つのセンサ６４のまとまりは、回動角度θが５度、１５度、３０度、４５度、６０度のいずれであるかを検知する。   The sensor 64 is a sensor for detecting the rotation angle θ of the washing tub 2 from the position of the nut member 63 in the front-rear direction Y. As the sensor 64, an optical sensor such as a photosensor can be used. In this case, the sensors 64 are provided in the same number as the recesses 51 </ b> C in the rotation unit 51, and are fixed to the frame 58 in a state of being aligned in the front-rear direction Y. Each sensor 64 is formed with a groove 64A penetrating the sensor 64 in the front-rear direction Y. In the sensor 64, the detection light crosses the groove 64A in the vertical direction Z. The nut member 63 is provided with a lever-shaped detected portion 63A called a dog. When the rotation angle θ is 5 degrees, 15 degrees, 30 degrees, 45 degrees, or 60 degrees, the detected portion 63A is fitted into the groove 64A of any one of the sensors 64 and detected in the groove 64A. Block out light. Therefore, the group of five sensors 64 detects whether the rotation angle θ is 5 degrees, 15 degrees, 30 degrees, 45 degrees, or 60 degrees.
