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に記載の洗濯乾燥機では、洗濯物が投入される回転槽部が組み込まれた外槽部が、傾斜回転支持軸を介して回転支持部材によって支持される。回転支持部材は、外槽部を挟むように一対に設けられ、それぞれの回転支持部材が、吊り棒を介して洗濯乾燥機の外枠によって支持される。外槽部には回動ワイヤ取付け部が設けられ、回動ワイヤ取付け部につながったワイヤが、外枠に設けられた傾斜回動モータの巻胴に巻回される。傾斜回動モータの回転に応じてワイヤが上がったり下がったりすることによって、外槽部が、傾斜回転支持軸まわりに傾斜回動する。これにより、洗濯物を回転槽部に投入する場合には外槽部を横向きに傾け、洗濯やすすぎや脱水の際には外槽部を縦形にして垂直方向に沿わせることができる。 In the washer / dryer described in Patent Document 1 below, the outer tub portion in which the rotary tub portion into which the laundry is loaded is incorporated is supported by the rotation support member via the inclined rotation support shaft. The rotation support members are provided in pairs so as to sandwich the outer tub portion, and each rotation support member is supported by the outer frame of the washer / dryer via a hanging rod. A rotating wire mounting portion is provided in the outer tank portion, and the wire connected to the rotating wire mounting portion is wound around the winding cylinder of the tilting rotating motor provided in the outer frame. The wire goes up and down according to the rotation of the tilt rotation motor, so that the outer tank portion tilts around the tilt rotation support shaft. As a result, when the laundry is put into the rotary tub, the outer tub can be tilted sideways, and when washing, rinsing or dehydrating, the outer tub can be made vertical and run vertically.

特開平４−１６６１９６号公報Japanese Unexamined Patent Publication No. 4-166196

特許文献１に記載の洗濯乾燥機では、それぞれの回転支持部材において吊り棒が取り付けられる部分は、回転支持部材において外槽部側とは反対側の外側面部に位置する。これでは、吊り棒が回転支持部材の外側へはみ出して配置されることによって洗濯乾燥機の大型化が懸念されるので、洗濯乾燥機の設置スペースの省スペース化を図ることが困難である。また、外槽部を回動可能に支持する回転支持部材では、剛性の向上が望まれる。 In the washer / dryer described in Patent Document 1, the portion to which the suspension rod is attached in each rotation support member is located on the outer surface portion of the rotation support member opposite to the outer tub portion side. In this case, since the hanging rods are arranged so as to protrude to the outside of the rotation support member, there is a concern that the size of the washer / dryer will be increased, so that it is difficult to save the installation space of the washer / dryer. Further, it is desired to improve the rigidity of the rotary support member that rotatably supports the outer tank portion.

この発明は、かかる背景のもとでなされたもので、垂直方向に対して交差するように回動可能な洗濯槽を含む構成において、設置スペースの省スペース化と、洗濯槽を回動可能に支持する部分における剛性の向上とを図れる洗濯機を提供することを目的とする。 The present invention was made under such a background, and in a configuration including a washing tub that can rotate so as to intersect in the vertical direction, the installation space can be saved and the washing tub can be rotated. It is an object of the present invention to provide a washing machine capable of improving the rigidity of a supporting portion.

本発明は、洗濯物を収容し、垂直方向に対して交差するように回動可能な洗濯槽と、前記洗濯槽の外側に配置され、前記洗濯槽を回動可能に支持する支持部材と、前記支持部材に設けられ、前記洗濯槽側へ折れ曲がった折曲部と、前記折曲部に取り付けられ、前記支持部材を弾性支持する弾性支持部材と、を含む、洗濯機である。 The present invention includes a washing tub that accommodates laundry and is rotatable so as to intersect in the vertical direction, and a support member that is arranged outside the washing tub and rotatably supports the washing tub. A washing machine including a bent portion provided on the support member and bent toward the washing tub side, and an elastic support member attached to the bent portion to elastically support the support member.

また、本発明は、前記支持部材と前記洗濯槽との間に配置され、前記洗濯槽を回動させる駆動機構を含むことを特徴とする。 Further, the present invention is characterized by including a drive mechanism that is arranged between the support member and the washing tub and rotates the washing tub.

また、本発明は、前記駆動機構は、一部が折れ曲がって形成されて前記支持部材に取り付けられるベース部を含むことを特徴とする。 Further, the present invention is characterized in that the drive mechanism includes a base portion which is partially bent and attached to the support member.

また、本発明は、前記支持部材は、前記洗濯槽を挟むように一対設けられ、一対の前記支持部材の間に架設されるビーム部材を含むことを特徴とする。 Further, the present invention is characterized in that the support members are provided in pairs so as to sandwich the washing tub, and include a beam member erected between the pair of support members.

また、本発明は、前記支持部材は、前記洗濯槽を挟むように一対設けられ、一対の前記支持部材と、一対の前記支持部材の下端部間に架設される底部材とを一体的に有する一体物の支持フレームを含むことを特徴とする。 Further, in the present invention, the support members are provided in pairs so as to sandwich the washing tub, and integrally include the pair of the support members and the bottom member erected between the lower ends of the pair of the support members. It is characterized by including a support frame for an integral object.

本発明によれば、垂直方向に対して交差するように回動可能な洗濯槽を含む洗濯機において、洗濯槽の外側に配置される支持部材が、洗濯槽を回動可能に支持する。
支持部材には、洗濯槽側へ折れ曲がった折曲部が設けられる。これにより、支持部材における剛性の向上を図れる。折曲部には、支持部材を弾性支持する弾性支持部材が取り付けられる。この場合、弾性支持部材は、支持部材に対する洗濯槽の反対側である外側へはみ出して配置されるのではなく、洗濯槽側、つまり、支持部材の内側に配置されるので、洗濯機の小型化を図れる。これにより、洗濯機の設置スペースの省スペース化を図れる。 According to the present invention, in a washing machine including a washing tub that is rotatable so as to intersect in the vertical direction, a support member arranged on the outside of the washing tub rotatably supports the washing tub.
The support member is provided with a bent portion that is bent toward the washing tub side. As a result, the rigidity of the support member can be improved. An elastic support member that elastically supports the support member is attached to the bent portion. In this case, the elastic support member is not arranged so as to protrude to the outside, which is the opposite side of the washing tub to the support member, but is arranged on the washing tub side, that is, inside the support member, so that the washing machine is downsized. Can be planned. As a result, the installation space of the washing machine can be saved.

また、本発明によれば、洗濯槽を回動させる駆動機構が、支持部材の外側へはみ出して配置されるのではなく、支持部材と洗濯槽との間に配置されるので、洗濯機の小型化を図れる。これにより、洗濯機の設置スペースの省スペース化を図れる。 Further, according to the present invention, the drive mechanism for rotating the washing tub is not arranged so as to protrude to the outside of the support member, but is arranged between the support member and the washing tub, so that the washing machine is compact. Can be made. As a result, the installation space of the washing machine can be saved.

また、本発明によれば、駆動機構において支持部材に取り付けられるベース部では、一部が折れ曲がって形成されることによって、剛性の向上が図られる。これにより、支持部材がベース部によって補強されるので、支持部材における剛性の一層の向上を図れる。 Further, according to the present invention, the rigidity of the base portion attached to the support member in the drive mechanism can be improved by being formed by bending a part of the base portion. As a result, the support member is reinforced by the base portion, so that the rigidity of the support member can be further improved.

また、本発明によれば、洗濯槽を挟むように一対設けられた支持部材の間にビーム部材が架設されることによって、それぞれの支持部材における剛性の一層の向上を図れる。 Further, according to the present invention, by installing a beam member between a pair of support members provided so as to sandwich the washing tub, the rigidity of each support member can be further improved.

また、本発明によれば、洗濯槽を挟むように一対設けられた支持部材と、これらの支持部材の下端間に架設された底部材とが一体化されて、一体物の支持フレームを構成するので、それぞれの支持部材における剛性の一層の向上を図れる。 Further, according to the present invention, a pair of support members provided so as to sandwich the washing tub and a bottom member erected between the lower ends of these support members are integrated to form an integral support frame. Therefore, the rigidity of each support member can be further improved.

以下には、図面を参照して、この発明の実施形態について具体的に説明する。図１は、この発明の一実施形態に係る洗濯機１の模式的な斜視図である。図１における上下方向を洗濯機１の上下方向Ｚといい、図１における左右方向を洗濯機１の前後方向Ｙといい、図１の紙面に略直交する横方向を左右方向Ｘという。上下方向Ｚは、垂直方向でもある。上下方向Ｚのうち、上側を上側Ｚ１といい、下側を下側Ｚ２という。前後方向Ｙのうち、図１における右側を前側Ｙ１といい、図１における左側を後側Ｙ２という。左右方向Ｘのうち、図１の紙面の手前側を左側Ｘ１といい、図１の紙面の奥側を右側Ｘ２という。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a schematic perspective view of a washing machine 1 according to an embodiment of the present invention. The vertical direction in FIG. 1 is referred to as the vertical direction Z of the washing machine 1, the horizontal direction in FIG. 1 is referred to as the front-rear direction Y of the washing machine 1, and the horizontal direction substantially orthogonal to the paper surface of FIG. 1 is referred to as the horizontal direction X. The vertical direction Z is also the vertical direction. Of the vertical directions Z, the upper side is called the upper side Z1 and the lower side is called the lower side Z2. Of the front-rear direction Y, the right side in FIG. 1 is referred to as the front side Y1, and the left side in FIG. 1 is referred to as the rear side Y2. Of the left-right directions X, the front side of the paper surface of FIG. 1 is referred to as the left side X1, and the back side of the paper surface of FIG. 1 is referred to as the right side X2.

洗濯機１には、乾燥機能を有する洗濯乾燥機も含まれるが、以下では、乾燥機能が省略されて洗濯運転だけを実行する洗濯機を例に取って洗濯機１について説明する。洗濯運転には、洗い工程とすすぎ工程と脱水工程とが含まれる。洗濯機１は、筐体２と、筐体２内に配置される洗濯槽３、支持フレーム４、弾性支持部材５、回動部６、ロック解除機構７および駆動機構８とを含む。 The washing machine 1 also includes a washer / dryer having a drying function, but the washing machine 1 will be described below by taking as an example a washing machine in which the drying function is omitted and only the washing operation is performed. The washing operation includes a washing step, a rinsing step, and a dehydration step. The washing machine 1 includes a housing 2, a washing tub 3, a support frame 4, an elastic support member 5, a rotating portion 6, an unlocking mechanism 7, and a driving mechanism 8 arranged in the housing 2.

筐体２は、たとえば金属製であり、ボックス状に形成される。筐体２には、前面２Ａと上面２Ｂとをつなぐ連結面２Ｃが設けられる。連結面２Ｃは、たとえば、前側Ｙ１へ向かうにつれて下降する傾斜面である。洗濯機１内に洗濯物を出し入れするための出入口（図示せず）が、前面２Ａと連結面２Ｃとに跨って形成される。 The housing 2 is made of metal, for example, and is formed in a box shape. The housing 2 is provided with a connecting surface 2C that connects the front surface 2A and the top surface 2B. The connecting surface 2C is, for example, an inclined surface that descends toward the front side Y1. An entrance (not shown) for putting in and taking out laundry in the washing machine 1 is formed so as to straddle the front surface 2A and the connecting surface 2C.

洗濯槽３は、外槽１０と、内槽１１とを含む。外槽１０は、たとえば樹脂製であり、有底円筒状に形成される。外槽１０の円中心を通る仮想の直線は、外槽１０の中心軸Ｊである。洗い工程やすすぎ工程では、外槽１０内に水が溜められる。外槽１０において底壁（図示せず）とは反対側の上端部に、洗濯機１内に出し入れされる洗濯物を通過させる円形状の開口１０Ａが形成される。外槽１０における左右の側面には、左右方向Ｘにおける外側へ突出した金属製の回動軸１２が１つずつ設けられる。図１では、左側Ｘ１の回動軸１２のみ図示される。これらの左右一対の回動軸１２は、左右方向Ｘから見て同じ位置に配置される。 The washing tub 3 includes an outer tub 10 and an inner tub 11. The outer tank 10 is made of resin, for example, and is formed in a bottomed cylindrical shape. The virtual straight line passing through the center of the circle of the outer tank 10 is the central axis J of the outer tank 10. In the washing step and the rinsing step, water is stored in the outer tank 10. A circular opening 10A is formed in the outer tub 10 at the upper end on the side opposite to the bottom wall (not shown) to allow laundry to be taken in and out of the washing machine 1 to pass through. On the left and right side surfaces of the outer tank 10, one metal rotation shaft 12 projecting outward in the left-right direction X is provided. In FIG. 1, only the rotation shaft 12 on the left side X1 is shown. The pair of left and right rotation shafts 12 are arranged at the same position when viewed from the left and right direction X.

内槽１１は、たとえば金属製であり、外槽１０よりも一回り小さい有底円筒状に形成される。内槽１１には洗濯物が収容される。内槽１１において底壁（図示せず）とは反対側の上端部に、内槽１１内に収容される洗濯物を通過させる円形状の開口１１Ａが形成される。内槽１１は、外槽１０内に同軸状で収容される。そのため、内槽１１の中心軸は、前述した中心軸Ｊである。内槽１１が外槽１０内に収容された状態では、外槽１０の開口１０Ａの内側に内槽１１の開口１１Ａが位置する。開口１０Ａおよび開口１１Ａが、筐体２の出入口（図示せず）に対向することによって、内槽１１内に洗濯物を出し入れすることができる。内槽１１の円周壁１１Ｂおよび底壁には、貫通孔１１Ｃが複数形成され、外槽１０内の水は、これらの貫通孔１１Ｃを介して、外槽１０と内槽１１との間で行き来できる。そのため、外槽１０内の水位と内槽１１内の水位とは一致する。洗濯運転では、内槽１１は、筐体２内に設けられたモータ（図示せず）からの駆動力を受けることによって、中心軸Ｊまわりに回転する。 The inner tank 11 is made of metal, for example, and is formed in a bottomed cylindrical shape that is one size smaller than the outer tank 10. Laundry is stored in the inner tub 11. A circular opening 11A through which the laundry housed in the inner tub 11 passes is formed at the upper end portion of the inner tub 11 on the side opposite to the bottom wall (not shown). The inner tank 11 is coaxially housed in the outer tank 10. Therefore, the central axis of the inner tank 11 is the above-mentioned central axis J. In the state where the inner tank 11 is housed in the outer tank 10, the opening 11A of the inner tank 11 is located inside the opening 10A of the outer tank 10. When the opening 10A and the opening 11A face the entrance / exit (not shown) of the housing 2, the laundry can be taken in and out of the inner tub 11. A plurality of through holes 11C are formed in the circumferential wall 11B and the bottom wall of the inner tank 11, and the water in the outer tank 10 travels between the outer tank 10 and the inner tank 11 through these through holes 11C. it can. Therefore, the water level in the outer tank 10 and the water level in the inner tank 11 match. In the washing operation, the inner tub 11 rotates around the central axis J by receiving a driving force from a motor (not shown) provided in the housing 2.

支持フレーム４は、金属製であり、左右一対の支持部材１３と、これらの支持部材１３の下端部間に架設されたビーム部材１４とを含む。一対の支持部材１３の間に、洗濯槽３が配置される。そのため、一対の支持部材１３は、洗濯槽３を左右方向Ｘから挟むように洗濯槽３の外側に配置される。それぞれの支持部材１３は、左右方向Ｘから見て略矩形状であって左右方向Ｘに薄い板状に形成される。つまり、それぞれの支持部材１３は、洗濯槽３に対向する方向である左右方向Ｘに板厚を有する。 The support frame 4 is made of metal and includes a pair of left and right support members 13 and a beam member 14 erected between the lower ends of these support members 13. The washing tub 3 is arranged between the pair of support members 13. Therefore, the pair of support members 13 are arranged on the outside of the washing tub 3 so as to sandwich the washing tub 3 from the left-right direction X. Each support member 13 has a substantially rectangular shape when viewed from the left-right direction X, and is formed in a thin plate shape in the left-right direction X. That is, each support member 13 has a plate thickness in the left-right direction X, which is the direction facing the washing tub 3.

洗濯槽３の外槽１０では、左側Ｘ１に突出した回動軸１２が、左側Ｘ１の支持部材１３を貫通し、軸受（図示せず）を介して左側Ｘ１の支持部材１３によって回動可能に支持される。外槽１０では、右側Ｘ２に突出した回動軸１２（図示せず）が、右側Ｘ２の支持部材１３を貫通し、軸受（図示せず）を介して右側Ｘ２の支持部材１３によって回動可能に支持される。これにより、洗濯槽３は、支持フレーム４の左右の支持部材１３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１２まわりに回動可能である。具体的には、洗濯槽３の回動に伴って、外槽１０および内槽１１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３の回動方向を回動方向Ｋという。 In the outer tub 10 of the washing tub 3, the rotating shaft 12 protruding to the left side X1 penetrates the support member 13 of the left side X1 and is rotatable by the support member 13 of the left side X1 via a bearing (not shown). Be supported. In the outer tank 10, the rotation shaft 12 (not shown) protruding to the right side X2 penetrates the support member 13 of the right side X2 and can be rotated by the support member 13 of the right side X2 via the bearing (not shown). Supported by. As a result, the washing tub 3 is supported by the left and right support members 13 of the support frame 4, and can rotate around the rotation shaft 12 so as to intersect the vertical direction Z. Specifically, as the washing tub 3 rotates, the central axes J of the outer tub 10 and the inner tub 11 incline in the front-rear direction Y with respect to the vertical direction Z. The rotation direction of the washing tub 3 is called the rotation direction K.

上下方向Ｚに沿って延びる仮想の基準軸Ｌと中心軸Ｊとの鋭角の交差角度は、基準軸Ｌに対する洗濯槽３の回動角度θである。回動角度θが小さいほど、洗濯槽３は直立姿勢に近くなり、回動角度θが大きいほど、洗濯槽３は、外槽１０の開口１０Ａおよび内槽１１の開口１１Ａが前側Ｙ１を向くように、前側Ｙ１へ傾斜した姿勢になる。回動角度θは、たとえば、５度、１５度、３０度、４５度、６０度の５段階で変更できる。この場合、洗濯機１での運用の一例として、洗濯運転の開始時に洗濯物を洗濯槽３に投入する際には、洗濯物の投入が容易となるように回動角度θが４５度に設定され、その後に洗濯物の負荷量を検知したり洗濯槽３に給水したりする場合には、回動角度θが５度に設定される。そして、洗い工程やすすぎ工程では、内槽１１内における洗濯物の位置の入れ替えを促進して効果的な洗いやすすぎを実現するために、回動角度θが５度と６０度との間で変動するように設定される。 The acute angle intersection angle between the virtual reference axis L and the central axis J extending along the vertical direction Z is the rotation angle θ of the washing tub 3 with respect to the reference axis L. The smaller the rotation angle θ, the closer the washing tub 3 is to the upright posture, and the larger the rotation angle θ, the more the opening 10A of the outer tub 10 and the opening 11A of the inner tub 11 face the front side Y1. In addition, the posture is inclined toward the front side Y1. The rotation angle θ can be changed in five stages of, for example, 5 degrees, 15 degrees, 30 degrees, 45 degrees, and 60 degrees. In this case, as an example of operation in the washing machine 1, when the laundry is put into the washing tub 3 at the start of the washing operation, the rotation angle θ is set to 45 degrees so that the laundry can be easily put in. Then, when the load amount of the laundry is detected or water is supplied to the washing tub 3, the rotation angle θ is set to 5 degrees. Then, in the washing step and rinsing step, the rotation angle θ is between 5 degrees and 60 degrees in order to promote the replacement of the positions of the laundry in the inner tub 11 and realize effective washing and rinsing. Set to fluctuate.

左側Ｘ１の支持部材１３において回動軸１２よりも下側Ｚ２の領域には、この支持部材１３を左右方向Ｘに貫通する開口１３Ａが形成される。開口１３Ａは、前後方向Ｙに長手の略長方形状に形成される。左側Ｘ１の支持部材１３の斜視図である図２を参照して、左側Ｘ１の支持部材１３において開口１３Ａの上側Ｚ１には、回動軸１２が挿通されるとともに回動部６が位置決めされる円形状の開口１３Ｂと、開口１３Ｂよりも前側Ｙ１に位置し、ロック解除機構７が嵌め込まれる矩形状の開口１３Ｃとが形成される。 In the support member 13 on the left side X1, an opening 13A that penetrates the support member 13 in the left-right direction X is formed in the region Z2 below the rotation shaft 12. The opening 13A is formed in a substantially rectangular shape long in the front-rear direction Y. With reference to FIG. 2, which is a perspective view of the support member 13 on the left side X1, the rotation shaft 12 is inserted into the upper Z1 of the opening 13A in the support member 13 on the left side X1, and the rotation portion 6 is positioned. A circular opening 13B and a rectangular opening 13C located on the front side Y1 of the opening 13B and into which the unlocking mechanism 7 is fitted are formed.

それぞれの支持部材１３では、前上側の角を斜めに切り取る傾斜部１３Ｄが形成され、上端部において傾斜部１３Ｄよりも後側Ｙ２における全域は、左右方向Ｘにおいて洗濯槽３側とは反対側へ略直角に折れ曲がったフランジ部１３Ｅを構成する。ここで、左右方向Ｘにおける洗濯槽３側とは、支持部材１３の内側であり、左側Ｘ１の支持部材１３の場合には右側Ｘ２であり、右側Ｘ２の支持部材１３の場合には左側Ｘ１である。逆に、左右方向Ｘにおいて洗濯槽３側とは反対側とは、支持部材１３の外側であり、左側Ｘ１の支持部材１３の場合には左側Ｘ１であり、右側Ｘ２の支持部材１３の場合には右側Ｘ２である。 In each support member 13, an inclined portion 13D is formed so as to diagonally cut off the front upper corner, and the entire area on the rear side Y2 of the inclined portion 13D at the upper end portion is on the side opposite to the washing tub 3 side in the left-right direction X. It constitutes a flange portion 13E that is bent at a substantially right angle. Here, the washing tub 3 side in the left-right direction X is the inside of the support member 13, the right side X2 in the case of the support member 13 on the left side X1, and the left side X1 in the case of the support member 13 on the right side X2. is there. On the contrary, in the left-right direction X, the side opposite to the washing tub 3 side is the outside of the support member 13, the left side X1 in the case of the support member 13 on the left side X1, and the support member 13 on the right side X2. Is the right side X2.

それぞれの支持部材１３には、洗濯槽３側へ折れ曲がった折曲部１３Ｆが一体的に設けられる。折曲部１３Ｆは、前側折曲部１３Ｇと、後側折曲部１３Ｈと、下側折曲部１３Ｉとを含む。前側折曲部１３Ｇは、支持部材１３の前端部において傾斜部１３Ｄよりも下側Ｚ２におけるほぼ全域を洗濯槽３側へ略直角に折り曲げることによって、上下方向Ｚに延びる帯状に形成される。後側折曲部１３Ｈは、支持部材１３の後端部のほぼ全域を洗濯槽３側へ略直角に折り曲げることによって、上下方向Ｚに延びる帯状に形成される。下側折曲部１３Ｉは、支持部材１３の下端部の全域を洗濯槽３側へ略直角に折り曲げることによって、前後方向Ｙに延びる帯状に形成される。 Each support member 13 is integrally provided with a bent portion 13F that is bent toward the washing tub 3 side. The bent portion 13F includes a front bent portion 13G, a rear bent portion 13H, and a lower bent portion 13I. The front bent portion 13G is formed in a band shape extending in the vertical direction Z by bending substantially the entire area of the support member 13 at the front end portion below the inclined portion 13D in Z2 at a substantially right angle toward the washing tub 3. The rear bent portion 13H is formed in a band shape extending in the vertical direction Z by bending substantially the entire rear end portion of the support member 13 toward the washing tub 3 side at a substantially right angle. The lower bent portion 13I is formed in a band shape extending in the front-rear direction Y by bending the entire lower end portion of the support member 13 toward the washing tub 3 side at a substantially right angle.

これらの折曲部１３Ｆにより、支持部材１３における剛性、特に左右方向Ｘにおける曲げ剛性の向上を図れる。なお、支持部材１３の上端部に設けられたフランジ部１３Ｅも支持部材１３の剛性の向上に寄与する。このように支持部材１３の剛性が向上することによって、支持部材１３を有する支持フレーム４全体の共振周波数が高くなるので、特に脱水工程で内槽１１が高速回転する際における支持フレーム４の振動を抑制できる。 With these bent portions 13F, the rigidity of the support member 13, particularly the bending rigidity in the left-right direction X can be improved. The flange portion 13E provided at the upper end portion of the support member 13 also contributes to the improvement of the rigidity of the support member 13. By improving the rigidity of the support member 13 in this way, the resonance frequency of the entire support frame 4 having the support member 13 becomes high, so that the vibration of the support frame 4 especially when the inner tank 11 rotates at high speed in the dehydration step is caused. Can be suppressed.

前側折曲部１３Ｇおよび後側折曲部１３Ｈのそれぞれにおいて、上側部分１３Ｊは、これらの折曲部を洗濯槽３側から上下方向Ｚに切り欠く切欠き１３Ｋが形成されることによって、下側部分１３Ｌよりも左右方向Ｘにおいて細い。切欠き１３Ｋは、洗濯運転中に振動した洗濯槽３が到達し得る位置にある。そのため、洗濯運転中の洗濯槽３が前側折曲部１３Ｇや後側折曲部１３Ｈに接触することが防止される。下側部分１３Ｌの上側領域には、下側部分１３Ｌを前後方向Ｙに貫通する大小の貫通穴１３Ｍが複数形成される。下側部分１３Ｌの下側領域において洗濯槽３側の端縁は、下側Ｚ２へ向かうにつれて洗濯槽３側とは反対側へ向かうように傾斜して形成される。これにより、下側部分１３Ｌの下側領域は、下側Ｚ２へ向かうにつれて左右方向Ｘに細くなる。 In each of the front bent portion 13G and the rear bent portion 13H, the upper portion 13J is formed on the lower side by forming a notch 13K that cuts out these bent portions in the vertical direction Z from the washing tub 3 side. It is thinner in the left-right direction X than the portion 13L. The notch 13K is in a position where the washing tub 3 vibrated during the washing operation can reach. Therefore, it is prevented that the washing tub 3 during the washing operation comes into contact with the front bent portion 13G and the rear bent portion 13H. In the upper region of the lower portion 13L, a plurality of large and small through holes 13M that penetrate the lower portion 13L in the front-rear direction Y are formed. In the lower region of the lower portion 13L, the edge on the washing tub 3 side is formed so as to be inclined toward the side opposite to the washing tub 3 side toward the lower Z2. As a result, the lower region of the lower portion 13L becomes thinner in the left-right direction X toward the lower Z2.

洗濯機１を下側Ｚ２から見た斜視図である図３を参照して、前側折曲部１３Ｇおよび後側折曲部１３Ｈのそれぞれにおける下側部分１３Ｌの上側領域には、受け部１５が１つずつ固定される。受け部１５は、たとえば樹脂製であり、上下方向Ｚにやや長手のボックス状に形成される。受け部１５には、その下面から上側Ｚ１へ窪む凹部１５Ａが形成される。受け部１５は、前側折曲部１３Ｇの下側部分１３Ｌに対しては前側Ｙ１から対向配置され、後側折曲部１３Ｈの下側部分１３Ｌに対しては後側Ｙ２から対向配置される。受け部１５に設けられた爪（図示せず）が下側部分１３Ｌの上側領域における一部の貫通穴１３Ｍ（図２参照）に嵌め込まれることによって、受け部１５が下側部分１３Ｌに位置決めされる。下側部分１３Ｌの上側領域における別の貫通穴１３Ｍに通されたボルト（図示せず）が受け部１５に組み付けられることによって、受け部１５は、下側部分１３Ｌに固定される。 With reference to FIG. 3, which is a perspective view of the washing machine 1 as viewed from the lower side Z2, a receiving portion 15 is provided in the upper region of the lower portion 13L of each of the front bending portion 13G and the rear bending portion 13H. It is fixed one by one. The receiving portion 15 is made of resin, for example, and is formed in a box shape slightly elongated in the vertical direction Z. The receiving portion 15 is formed with a recess 15A that is recessed from the lower surface to the upper side Z1. The receiving portion 15 is arranged to face the lower portion 13L of the front bent portion 13G from the front side Y1 and is arranged to face the lower portion 13L of the rear bent portion 13H from the rear side Y2. The receiving portion 15 is positioned in the lower portion 13L by fitting a claw (not shown) provided in the receiving portion 15 into a part of the through holes 13M (see FIG. 2) in the upper region of the lower portion 13L. To. The receiving portion 15 is fixed to the lower portion 13L by assembling a bolt (not shown) passed through another through hole 13M in the upper region of the lower portion 13L to the receiving portion 15.

弾性支持部材５は、吊り棒とも呼ばれ、下端部に摩擦ダンパ１６を有する上下に長手の棒状に形成される。弾性支持部材５は、４本存在し、筐体２内において上側Ｚ１から見た平面視における四隅に１本ずつ配置される。これらの弾性支持部材５は、筐体２の上部、詳しくは、筐体２の一部を構成する金属製の外枠（図示せず）から吊り下がった状態にある。 The elastic support member 5 is also called a suspension rod, and is formed in the shape of a vertically elongated rod having a friction damper 16 at the lower end. There are four elastic support members 5, and one is arranged at each of the four corners in the housing 2 in a plan view from the upper side Z1. These elastic support members 5 are suspended from the upper part of the housing 2, specifically, a metal outer frame (not shown) that constitutes a part of the housing 2.

左側Ｘ１で前後に並ぶ２本の弾性支持部材５のうち、前側Ｙ１の弾性支持部材５の下端部は、左側Ｘ１の支持部材１３の前側折曲部１３Ｇに設けられた受け部１５に連結され、後側Ｙ２の弾性支持部材５の下端部は、左側Ｘ１の支持部材１３の後側折曲部１３Ｈに設けられた受け部１５に連結される。右側Ｘ２で前後に並ぶ２本の弾性支持部材５のうち、前側Ｙ１の弾性支持部材５の下端部は、右側Ｘ２の支持部材１３の前側折曲部１３Ｇに設けられた受け部１５に連結され、後側Ｙ２の弾性支持部材５（図示せず）の下端部は、右側Ｘ２の支持部材１３の後側折曲部１３Ｈに設けられた受け部１５（図示せず）に連結される。 Of the two elastic support members 5 arranged in the front-rear direction on the left side X1, the lower end of the elastic support member 5 on the front side Y1 is connected to the receiving portion 15 provided on the front side bent portion 13G of the support member 13 on the left side X1. The lower end of the elastic support member 5 on the rear side Y2 is connected to the receiving portion 15 provided on the rear bent portion 13H of the support member 13 on the left side X1. Of the two elastic support members 5 arranged in the front-rear direction on the right side X2, the lower end portion of the elastic support member 5 on the front side Y1 is connected to the receiving portion 15 provided on the front side bent portion 13G of the support member 13 on the right side X2. The lower end of the elastic support member 5 (not shown) on the rear side Y2 is connected to the receiving portion 15 (not shown) provided on the rear bent portion 13H of the support member 13 on the right side X2.

それぞれの弾性支持部材５の下端部は、受け部１５の凹部１５Ａに下側Ｚ２から嵌め込まれることによって受け部１５に連結され、受け部１５を介して前側折曲部１３Ｇや後側折曲部１３Ｈに取り付けられる。弾性支持部材５において下端部よりも上側Ｚ１の棒状部分は、受け部１５を貫通して受け部１５よりも上側Ｚ１へ延び、前述した外枠（図示せず）に連結される。これにより、支持部材１３を有する支持フレーム４と、支持フレーム４によって支持された洗濯槽３と、内槽１１を回転させるモータ（図示せず）とは、弾性支持部材５によって弾性支持される。 The lower end of each elastic support member 5 is connected to the receiving portion 15 by being fitted into the recess 15A of the receiving portion 15 from the lower side Z2, and the front bent portion 13G and the rear bent portion are connected via the receiving portion 15. It is attached to 13H. In the elastic support member 5, the rod-shaped portion of Z1 above the lower end portion penetrates the receiving portion 15 and extends to Z1 above the receiving portion 15 and is connected to the above-mentioned outer frame (not shown). As a result, the support frame 4 having the support member 13, the washing tub 3 supported by the support frame 4, and the motor (not shown) that rotates the inner tub 11 are elastically supported by the elastic support member 5.

このように支持部材１３から左右方向Ｘにおける洗濯槽３側へ折れ曲がった前側折曲部１３Ｇや後側折曲部１３Ｈに取り付けられる弾性支持部材５は、支持部材１３に対する洗濯槽３の反対側である外側へはみ出して配置されるのではなく、洗濯槽３側、つまり、支持部材１３の内側に配置される。これにより、左右方向Ｘにおける洗濯機１の小型化を図れる。これにより、洗濯機１の設置スペースの省スペース化を図れる。そのため、回動部６やロック解除機構７や駆動機構８のように洗濯槽３を回動させる構成を有する洗濯機１であっても、このような構成を備えない通常の洗濯機と同じ大きさにおさめることができるので、従来サイズの防水パンに設置することができる。 The elastic support member 5 attached to the front bent portion 13G and the rear bent portion 13H bent from the support member 13 toward the washing tub 3 side in the left-right direction X is on the opposite side of the washing tub 3 with respect to the support member 13. It is not arranged so as to protrude to a certain outside, but is arranged on the washing tub 3 side, that is, inside the support member 13. As a result, the washing machine 1 can be miniaturized in the left-right direction X. As a result, the installation space of the washing machine 1 can be saved. Therefore, even a washing machine 1 having a structure for rotating the washing tub 3 such as a rotating portion 6, an unlocking mechanism 7, and a drive mechanism 8 has the same size as a normal washing machine without such a structure. Since it can be stored in a small size, it can be installed in a conventional size waterproof pan.

ビーム部材１４は、左右方向Ｘに細長い柱状に形成され、２本設けられる。ビーム部材１４は、一対の支持部材１３の下側折曲部１３Ｉにおける前端部間と後端部間とに１本ずつ架設される。これによって、それぞれの支持部材１３における剛性および支持フレーム４全体の剛性の一層の向上を図れる。そのため、一対の支持部材１３間での捩れを抑制できるので、この捩れによって洗濯槽３の回動軸１２に負担がかかることを抑制できる。 The beam member 14 is formed in an elongated columnar shape in the left-right direction X, and two beam members 14 are provided. One beam member 14 is erected between the front end portion and the rear end portion of the lower bent portion 13I of the pair of support members 13. As a result, the rigidity of each of the support members 13 and the rigidity of the entire support frame 4 can be further improved. Therefore, since the twist between the pair of support members 13 can be suppressed, it is possible to suppress the load on the rotating shaft 12 of the washing tub 3 due to this twist.

回動部６は、左右方向Ｘに薄く、左右方向Ｘから見て前側Ｙ１へ膨出した略扇状に形成された金属製の板である。回動部６は、回動方向Ｋに沿う円弧状に形成されて前側Ｙ１へ膨出した外周縁６Ａを有する。回動部６において外周縁６Ａの曲率中心と一致する位置には、回動部６を左右方向Ｘに貫通する貫通穴６Ｂが形成される。外周縁６Ａには、複数、ここでは、５つの凹部６Ｃが形成される。これらの凹部６Ｃは、貫通穴６Ｂへ向けて窪みつつ回動部６を左右方向Ｘに貫通し、回動方向Ｋに並んで配置される。隣り合う凹部６Ｃの間隔は、一定であってもよいし、回動部６の位置に応じて異なってもよい。この実施形態では、回動角度θが５度、１５度、３０度、４５度、６０度に設定されることに応じて、図３での姿勢における回動部６において、最も後側Ｙ２およびその前隣に位置する２つの凹部６Ｃの間隔は、回動方向Ｋつまり貫通穴６Ｂを中心とする周方向において１０度であり、他の隣り合う凹部６Ｃ同士の間隔は、一律に１５度である。 The rotating portion 6 is a metal plate that is thin in the left-right direction X and is formed in a substantially fan shape that bulges toward the front side Y1 when viewed from the left-right direction X. The rotating portion 6 has an outer peripheral edge 6A formed in an arc shape along the rotating direction K and bulging toward the front side Y1. A through hole 6B that penetrates the rotating portion 6 in the left-right direction X is formed at a position of the rotating portion 6 that coincides with the center of curvature of the outer peripheral edge 6A. A plurality of, here, five recesses 6C are formed on the outer peripheral edge 6A. These recesses 6C penetrate the rotating portion 6 in the left-right direction X while being recessed toward the through hole 6B, and are arranged side by side in the rotating direction K. The distance between the adjacent recesses 6C may be constant or may differ depending on the position of the rotating portion 6. In this embodiment, the rearmost Y2 and the rotating portion 6 in the posture shown in FIG. 3 correspond to the rotation angles θ being set to 5 degrees, 15 degrees, 30 degrees, 45 degrees, and 60 degrees. The distance between the two recesses 6C located adjacent to the front thereof is 10 degrees in the rotation direction K, that is, the circumferential direction centered on the through hole 6B, and the distance between the other adjacent recesses 6C is uniformly 15 degrees. is there.

回動部６は、左側Ｘ１の支持部材１３よりも左側Ｘ１に配置される。洗濯槽３の外槽１０において左側Ｘ１に突出して左側Ｘ１の支持部材１３を貫通した回動軸１２が、回動部６の貫通穴６Ｂに挿通され、回動部６に固定される。これにより、回動部６は、回動軸１２を介して、洗濯槽３に対して一体回動可能に連結される。 The rotating portion 6 is arranged on the left side X1 of the support member 13 on the left side X1. In the outer tub 10 of the washing tub 3, the rotating shaft 12 that protrudes to the left side X1 and penetrates the support member 13 of the left side X1 is inserted into the through hole 6B of the rotating portion 6 and fixed to the rotating portion 6. As a result, the rotating portion 6 is integrally rotatably connected to the washing tub 3 via the rotating shaft 12.

図３での姿勢における回動部６において外周縁６Ａの後端には、下側Ｚ２、具体的には、貫通穴６Ｂを中心とする回動部６の径方向Ｒにおける外側へ突出した延設部６Ｄが一体的に設けられる。延設部６Ｄは、径方向Ｒに長手で左右方向Ｘに薄い板状に形成される。延設部６Ｄには、径方向Ｒに長手で延設部６Ｄを左右方向Ｘに貫通するガイド穴６Ｅが形成される。ガイド穴６Ｅの長手方向における両端は、塞がれた状態にある。ガイド穴６Ｅは、左側Ｘ１の支持部材１３の開口１３Ａと上下方向Ｚにおいて同じ位置にある。回動角度θが５度〜６０度におけるどの値であっても、ガイド穴６Ｅは、常に、開口１３Ａに対して左側Ｘ１から対向する。 In the rotating portion 6 in the posture shown in FIG. 3, at the rear end of the outer peripheral edge 6A, a lower Z2, specifically, a extending portion protruding outward in the radial direction R of the rotating portion 6 centered on the through hole 6B. The installation part 6D is integrally provided. The extension portion 6D is formed in the shape of a thin plate that is long in the radial direction R and thin in the left-right direction X. The extension portion 6D is formed with a guide hole 6E that is longitudinally longitudinal in the radial direction R and penetrates the extension portion 6D in the left-right direction X. Both ends of the guide hole 6E in the longitudinal direction are in a closed state. The guide hole 6E is located at the same position in the vertical direction Z as the opening 13A of the support member 13 on the left side X1. The guide hole 6E always faces the opening 13A from the left side X1 regardless of the value of the rotation angle θ from 5 degrees to 60 degrees.

ロック解除機構７は、左側Ｘ１の支持部材１３の左側面に固定される。ロック解除機構７は、本体部１７とロック部１８とを含む。本体部１７には、ソレノイドなどで構成されたアクチュエータ（図示せず）が設けられる。ロック部１８は、本体部１７から後側Ｙ２、厳密には、後上側へ突出した凸状に形成され、本体部１７によって前後方向Ｙへスライド可能に支持される。本体部１７のアクチュエータが作動することによって、ロック部１８は、最も後側Ｙ２へ進出した進出位置と、最も前側Ｙ１へ退避した退避位置との間をスライドする。 The unlock mechanism 7 is fixed to the left side surface of the support member 13 on the left side X1. The lock release mechanism 7 includes a main body portion 17 and a lock portion 18. The main body 17 is provided with an actuator (not shown) composed of a solenoid or the like. The lock portion 18 is formed in a convex shape protruding from the main body portion 17 to the rear side Y2, strictly speaking, to the rear upper side, and is slidably supported by the main body portion 17 in the front-rear direction Y. By operating the actuator of the main body portion 17, the lock portion 18 slides between the advance position advanced to the rearmost Y2 and the retracted position retracted to the frontmost Y1.

図３のロック部１８は、進出位置にある。回動部６におけるいずれかの凹部６Ｃとロック部１８とが回動方向Ｋにおいて同じ位置にある場合には、ロック部１８は、進出位置まで進出することによって、回動方向Ｋにおいて同じ位置の凹部６Ｃに嵌まり込む。これにより、回動部６および洗濯槽３の回動がロックされる。この状態で、ロック部１８が退避位置まで退避すると、ロック部１８は、凹部６Ｃから外れるので、回動部６および洗濯槽３のロックが解除される。 The lock portion 18 in FIG. 3 is in the advanced position. When any of the recesses 6C and the lock portion 18 in the rotating portion 6 are at the same position in the rotation direction K, the lock portion 18 advances to the advance position so that the lock portion 18 is at the same position in the rotation direction K. It fits into the recess 6C. As a result, the rotation of the rotating portion 6 and the washing tub 3 is locked. When the lock portion 18 is retracted to the retracted position in this state, the lock portion 18 is disengaged from the recess 6C, so that the rotating portion 6 and the washing tub 3 are unlocked.

図３では、進出位置のロック部１８が、最も上側Ｚ１かつ最も前側Ｙ１に位置する凹部６Ｃに嵌まり込んだ状態にある。このとき、回動角度θ（図１参照）が６０度になった状態で、回動部６および洗濯槽３の回動がロックされる。ロック部１８が嵌め込まれる凹部６Ｃが、後側Ｙ２に位置する別の凹部６Ｃになるにつれて、回動角度θが小さくなり、ロック部１８が最も後側Ｙ２の凹部６Ｃに嵌まり込んだ状態では、回動角度θが５度になった状態で、回動部６および洗濯槽３の回動がロックされる。 In FIG. 3, the lock portion 18 at the advanced position is in a state of being fitted into the recess 6C located at the uppermost Z1 and the frontmost Y1. At this time, the rotation of the rotating portion 6 and the washing tub 3 is locked while the rotation angle θ (see FIG. 1) is 60 degrees. As the recess 6C into which the lock portion 18 is fitted becomes another recess 6C located on the rear side Y2, the rotation angle θ becomes smaller, and the lock portion 18 is fitted into the recess 6C on the rearmost side Y2. The rotation of the rotating portion 6 and the washing tub 3 is locked when the rotation angle θ is 5 degrees.

図４は、駆動機構８の斜視図である。図４を参照して、駆動機構８は、洗濯槽３を回動させる機構であり、ベース部３０と、支持部３１と、ねじ軸３２と、モータ３３と、カップリング３４と、ナット部材３５と、センサ３６とを含む。 FIG. 4 is a perspective view of the drive mechanism 8. With reference to FIG. 4, the drive mechanism 8 is a mechanism for rotating the washing tub 3, and includes a base portion 30, a support portion 31, a screw shaft 32, a motor 33, a coupling 34, and a nut member 35. And the sensor 36.

ベース部３０は、たとえば金属板を折り曲げることによって形成され、縦壁３７と上下一対の横壁３８とを一体的に含む。縦壁３７は、左右方向Ｘに薄く前後方向Ｙに長手の長方形の板状に形成される。横壁３８は、上下方向Ｚに薄く前後方向Ｙに長手の長方形の板状に形成される。一対の横壁３８のうち、上側Ｚ１の横壁３８は、縦壁３７の上端の全域から連続して左側Ｘ１へ延び、下側Ｚ２の横壁３８は、縦壁３７の下端のほぼ全域から連続して左側Ｘ１へ延びる。 The base portion 30 is formed by, for example, bending a metal plate, and integrally includes a vertical wall 37 and a pair of upper and lower horizontal walls 38. The vertical wall 37 is formed in the shape of a rectangular plate that is thin in the left-right direction X and long in the front-rear direction Y. The lateral wall 38 is formed in the shape of a rectangular plate that is thin in the vertical direction Z and long in the front-rear direction Y. Of the pair of horizontal walls 38, the horizontal wall 38 of the upper Z1 continuously extends from the entire upper end of the vertical wall 37 to the left side X1, and the horizontal wall 38 of the lower Z2 continues from almost the entire lower end of the vertical wall 37. Extend to the left side X1.

それぞれの横壁３８の左端部は、フランジ部３８Ａとして、前後方向Ｙにおける全域に亘って上下方向Ｚにおける外側へ略直角に折れ曲がって形成される。上側Ｚ１の横壁３８のフランジ部３８Ａは、上側Ｚ１へ折れ曲がって形成され、下側Ｚ２の横壁３８のフランジ部３８Ａは、下側Ｚ２へ折れ曲がって形成される。それぞれのフランジ部３８Ａには、ねじ穴３８Ｂが形成される。 The left end portion of each side wall 38 is formed as a flange portion 38A by bending outward at a substantially right angle in the vertical direction Z over the entire area in the front-rear direction Y. The flange portion 38A of the side wall 38 of the upper Z1 is formed by bending toward the upper side Z1, and the flange portion 38A of the side wall 38 of the lower side Z2 is formed by bending toward the lower side Z2. A screw hole 38B is formed in each flange portion 38A.

このように、ベース部３０は、縦壁３７と横壁３８との境界やフランジ部３８Ａの周辺において一部がクランク状に折れ曲がって形成される。ベース部３０には、縦壁３７と上下一対の横壁３８とによって囲まれた収容空間３０Ａが形成される。収容空間３０Ａには、支持部３１、ねじ軸３２、カップリング３４、ナット部材３５およびセンサ３６が収容される。 As described above, the base portion 30 is formed by being partially bent like a crank at the boundary between the vertical wall 37 and the horizontal wall 38 and around the flange portion 38A. A storage space 30A surrounded by a vertical wall 37 and a pair of upper and lower horizontal walls 38 is formed in the base portion 30. The support portion 31, the screw shaft 32, the coupling 34, the nut member 35, and the sensor 36 are accommodated in the accommodation space 30A.

ベース部３０は、洗濯槽３に対して左右方向Ｘに並ぶように左側Ｘ１の支持部材１３と洗濯槽３との間に配置され、上下一対のフランジ部３８Ａが、左側Ｘ１の支持部材１３における開口１３Ａの周縁部に対して右側Ｘ２から対向配置される（図１参照）。左側Ｘ１の支持部材１３に組み付けられたボルト３９（図１参照）がそれぞれのフランジ部３８Ａのねじ穴３８Ｂにも組み付けられることによって、ベース部３０は、左側Ｘ１の支持部材１３に取り付けられる。前述したように一部が折れ曲がって形成されたベース部３０では剛性の向上が図られるので、支持部材１３がベース部３０によって補強される。これにより、支持部材１３における剛性の一層の向上を図れる。ベース部３０の収容空間３０Ａは、開口１３Ａを介して左側Ｘ１の支持部材１３から左側Ｘ１へ露出される（図１参照）。 The base portion 30 is arranged between the support member 13 on the left side X1 and the washing tub 3 so as to line up in the left-right direction X with respect to the washing tub 3, and a pair of upper and lower flange portions 38A are formed on the support member 13 on the left side X1. It is arranged to face the peripheral edge of the opening 13A from the right side X2 (see FIG. 1). The base portion 30 is attached to the support member 13 of the left side X1 by assembling the bolt 39 (see FIG. 1) assembled to the support member 13 of the left side X1 to the screw hole 38B of each flange portion 38A. As described above, the support member 13 is reinforced by the base portion 30 because the rigidity of the base portion 30 formed by being partially bent is improved.

In this state, the screw shaft 32 is supported by a pair of front and rear support portions 31 so as to be rotatable on both sides.

モータ３３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３２と同軸状に配置される出力軸４４を有する。モータ３３には、前後方向Ｙに薄い板状のブラケット４５が後側Ｙ２から取り付けられる。出力軸４４は、ブラケット４５から後側Ｙ２へ露出される。出力軸４４は、ねじ軸３２の前端部において前側Ｙ１の支持部３１の本体部４０よりも前側Ｙ１へはみ出た部分に対して、前側Ｙ１から対向配置される。ブラケット４５の左端部における上端部および下端部は、上下一対のフランジ部４５Ａとして後側Ｙ２へ略直角に折り曲げられ、それぞれのフランジ部４５Ａには、ねじ穴４５Ｂが形成される。 The motor 33 is a general electric motor, and has an output shaft 44 that protrudes to the rear side Y2 and is arranged coaxially with the screw shaft 32. A thin plate-shaped bracket 45 is attached to the motor 33 in the front-rear direction Y from the rear side Y2. The output shaft 44 is exposed from the bracket 45 to the rear side Y2. The output shaft 44 is arranged to face the portion of the front end of the screw shaft 32 that protrudes from the main body 40 of the support portion 31 of the front side Y1 toward the front side Y1 from the front side Y1. The upper end and the lower end of the left end of the bracket 45 are bent at substantially right angles to the rear side Y2 as a pair of upper and lower flanges 45A, and screw holes 45B are formed in each of the flanges 45A.

モータ３３は、ベース部３０よりも前側Ｙ１において、左側Ｘ１の支持部材１３と洗濯槽３との間に配置され、ブラケット４５におけるそれぞれのフランジ部４５Ａが、左側Ｘ１の支持部材１３における開口１３Ａの周縁部に対して右側Ｘ２から対向配置される（図１参照）。左側Ｘ１の支持部材１３に組み付けられたボルト４６（図１参照）がそれぞれのフランジ部４５Ａのねじ穴４５Ｂにも組み付けられることによって、モータ３３は、ブラケット４５を介して、左側Ｘ１の支持部材１３に固定される。この状態のモータ３３は、開口１３Ａを介して左側Ｘ１の支持部材１３から左側Ｘ１へ露出される（図１参照）。 The motor 33 is arranged between the support member 13 on the left side X1 and the washing tub 3 on the front side Y1 of the base portion 30, and each flange portion 45A on the bracket 45 has an opening 13A on the support member 13 on the left side X1. It is arranged to face the peripheral edge from the right side X2 (see FIG. 1). The bolt 46 (see FIG. 1) assembled to the support member 13 of the left side X1 is also assembled to the screw hole 45B of each flange portion 45A, so that the motor 33 can be attached to the support member 13 of the left side X1 via the bracket 45. Is fixed to. The motor 33 in this state is exposed from the support member 13 on the left side X1 to the left side X1 through the opening 13A (see FIG. 1).

カップリング３４は、モータ３３の出力軸４４の後端部に対して一体回転可能に外嵌された筒状の出力部４７と、ねじ軸３２の前端部に対して一体回転可能に外嵌された筒状の入力部４８と、出力部４７と入力部４８との間に配置される緩衝部４９とを含む。筒状の出力部４７は、その周方向に並んで後側Ｙ２へ突出した複数の突出部４７Ａを有する。筒状の入力部４８は、その周方向に並んで前側Ｙ１へ突出した複数の突出部４８Ａを有する。突出部４７Ａと突出部４８Ａとは、出力部４７および入力部４８の周方向において１つずつ交互に並んだ状態にある。隣り合う突出部４７Ａと突出部４８Ａと間に、緩衝部４９が配置される。緩衝部４９は、ゴムやバネなどの弾性体で構成される。出力軸４４とねじ軸３２とは、カップリング３４を介して一体回転可能に連結される。そのため、モータ３３が駆動されて出力軸４４が回転すると、ねじ軸３２は、出力軸４４と一体回転する。 The coupling 34 is integrally rotatably fitted to the rear end of the output shaft 44 of the motor 33, and is integrally rotatably fitted to the front end of the screw shaft 32. It includes a tubular input unit 48 and a buffer unit 49 arranged between the output unit 47 and the input unit 48. The tubular output portion 47 has a plurality of projecting portions 47A that are aligned in the circumferential direction and project to the rear side Y2. The tubular input portion 48 has a plurality of protruding portions 48A that are aligned in the circumferential direction and project to the front side Y1. The projecting portions 47A and the projecting portions 48A are in a state of being alternately arranged one by one in the circumferential direction of the output unit 47 and the input unit 48. A buffer portion 49 is arranged between the adjacent protrusions 47A and 48A. The shock absorber 49 is made of an elastic body such as rubber or a spring. The output shaft 44 and the screw shaft 32 are integrally rotatably connected via a coupling 34. Therefore, when the motor 33 is driven and the output shaft 44 rotates, the screw shaft 32 rotates integrally with the output shaft 44.

ナット部材３５は、本体部５０と、連結部５１と、被検知部５２とを含む。本体部５０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構成し、このねじ山とねじ軸３２のねじ山３２Ａとが互いに螺合するように、ねじ軸３２に対して外嵌される。モータ３３の駆動に応じてねじ軸３２が回転すると、ねじ軸３２の回転に伴って、ナット部材３５全体が、ねじ軸３２の軸方向、つまり、前後方向Ｙに沿って移動する。 The nut member 35 includes a main body portion 50, a connecting portion 51, and a detected portion 52. The main body 50 constitutes an annular nut in which spirally extending threads (not shown) are formed on the inner peripheral surface, so that the threads and the threads 32A of the screw shaft 32 are screwed together. , It is fitted externally to the screw shaft 32. When the screw shaft 32 rotates in response to the drive of the motor 33, the entire nut member 35 moves along the axial direction of the screw shaft 32, that is, in the front-rear direction Y, as the screw shaft 32 rotates.

連結部５１は、たとえば金属板を折り曲げることによって形成され、第１部５１Ａと、第２部５１Ｂと、第３部５１Ｃとを一体的に有する。第１部５１Ａは、前後方向Ｙに薄く上下方向Ｚに延びる板状に形成され、ボルト５３によって本体部５０に固定される。第２部５１Ｂは、左右方向Ｘに薄く上下方向Ｚに延びる板状に形成され、第１部５１Ａの左端縁から前側Ｙ１へ突出し、ベース部３０の収容空間３０Ａから左側Ｘ１にはみ出して配置され、本体部５０に対して左側Ｘ１から対向する（後述する図６も参照）。第２部５１Ｂには、第２部５１Ｂを左右方向Ｘに貫通する貫通穴５１Ｄが形成される。 The connecting portion 51 is formed by, for example, bending a metal plate, and integrally includes a first portion 51A, a second portion 51B, and a third portion 51C. The first portion 51A is formed in a plate shape that is thin in the front-rear direction Y and extends in the vertical direction Z, and is fixed to the main body portion 50 by a bolt 53. The second portion 51B is formed in a plate shape thinly extending in the vertical direction X in the left-right direction X, projects from the left end edge of the first portion 51A to the front side Y1, and is arranged so as to protrude from the accommodation space 30A of the base portion 30 to the left side X1. , Facing the main body 50 from the left side X1 (see also FIG. 6 described later). A through hole 51D is formed in the second portion 51B so as to penetrate the second portion 51B in the left-right direction X.

第２部５１Ｂは、回動部６の延設部６Ｄに対して右側Ｘ２から対向し、貫通穴５１Ｄには、延設部６Ｄのガイド穴６Ｅに左側Ｘ１から挿入された連結ピン５４が挿入される（図１参照）。連結ピン５４は、貫通穴５１Ｄおよびガイド穴６Ｅのそれぞれに対して外れ不能であり、ナット部材３５は、連結ピン５４を介して、回動部６に連結される。そのため、ねじ軸３２の回転に伴ってナット部材３５が前後方向Ｙに沿って移動すると、回動部６が、ナット部材３５によって前後方向Ｙに引っ張られることにより、洗濯槽３を伴って回動する。回動部６が回動する際、連結ピン５４は、ガイド穴６Ｅ内においてガイド穴６Ｅの長手方向に沿って移動する。第３部５１Ｃは、上下方向Ｚに薄い板状に形成され、第１部５１Ａの下端縁から前側Ｙ１へ突出し、本体部５０に対して下側Ｚ２から対向する。 The second portion 51B faces the extension portion 6D of the rotating portion 6 from the right side X2, and the connecting pin 54 inserted from the left side X1 into the guide hole 6E of the extension portion 6D is inserted into the through hole 51D. (See FIG. 1). The connecting pin 54 cannot be detached from each of the through hole 51D and the guide hole 6E, and the nut member 35 is connected to the rotating portion 6 via the connecting pin 54. Therefore, when the nut member 35 moves along the front-rear direction Y with the rotation of the screw shaft 32, the rotating portion 6 is pulled in the front-rear direction Y by the nut member 35 and rotates with the washing tub 3. To do. When the rotating portion 6 rotates, the connecting pin 54 moves in the guide hole 6E along the longitudinal direction of the guide hole 6E. The third portion 51C is formed in a thin plate shape in the vertical direction Z, projects from the lower end edge of the first portion 51A to the front side Y1, and faces the main body portion 50 from the lower side Z2.

被検知部５２は、左右方向Ｘに薄い板状に形成され、固定部５２Ａと先端部５２Ｂとを一体的に有する。固定部５２Ａは、連結部５１の第３部５１Ｃに対して下側Ｚ２から重なるように配置され、ボルト５５によって第３部５１Ｃに固定される。先端部５２Ｂは、ドグとも呼ばれ、固定部５２Ａの前端部から右側Ｘ２に延びるレバー状に形成される。 The detected portion 52 is formed in a thin plate shape in the left-right direction X, and has a fixed portion 52A and a tip portion 52B integrally. The fixing portion 52A is arranged so as to overlap the third portion 51C of the connecting portion 51 from the lower side Z2, and is fixed to the third portion 51C by the bolt 55. The tip portion 52B, also called a dog, is formed in a lever shape extending from the front end portion of the fixing portion 52A to the right side X2.

センサ３６は、前後方向Ｙにおけるナット部材３５の位置から洗濯槽３の回動角度θを検出するためのセンサであり、センサ３６として、フォトセンサなどの光学式の非接触センサを用いることができる。フォトセンサである場合におけるセンサ３６の左側面には、右側Ｘ２へ窪みつつセンサ３６を前後方向Ｙに貫通する溝３６Ａが形成され、センサ３６では、検知光が溝３６Ａを上下方向Ｚに横切った状態にある。センサ３６は、回動部６の凹部６Ｃと同数、つまり、この実施形態では５つ存在し、それぞれの溝３６Ａが前後方向Ｙから見て重なるように、ベース部３０の縦壁３７における下側領域において前後方向Ｙに並んで配置される。それぞれのセンサ３６は、ボルト５６によって縦壁３７に固定される。隣り合うセンサ３６の間隔は、隣り合う凹部６Ｃの間隔に対応するように設定される。そのため、この実施形態では、後側Ｙ２の４つのセンサ３６において隣り合うセンサ３６同士の間隔は一定であるが、最も前側Ｙ１およびその後隣に位置する２つのセンサ３６の間隔は、他の隣り合うセンサ３６同士の間隔よりも狭い。 The sensor 36 is a sensor for detecting the rotation angle θ of the washing tub 3 from the position of the nut member 35 in the front-rear direction Y, and an optical non-contact sensor such as a photo sensor can be used as the sensor 36. .. In the case of a photo sensor, a groove 36A is formed on the left side surface of the sensor 36 so as to penetrate the sensor 36 in the front-rear direction Y while being recessed to the right side X2, and in the sensor 36, the detection light crosses the groove 36A in the vertical direction Z. It is in a state. There are the same number of sensors 36 as the recesses 6C of the rotating portion 6, that is, five sensors 36 in this embodiment, and the lower side of the vertical wall 37 of the base portion 30 so that the grooves 36A overlap each other when viewed from the front-rear direction Y. They are arranged side by side in the front-back direction Y in the region. Each sensor 36 is fixed to the vertical wall 37 by bolts 56. The distance between the adjacent sensors 36 is set so as to correspond to the distance between the adjacent recesses 6C. Therefore, in this embodiment, the distance between the adjacent sensors 36 in the four sensors 36 on the rear side Y2 is constant, but the distance between the two sensors 36 located on the frontmost side Y1 and the two sensors 36 next to each other is adjacent to each other. It is narrower than the distance between the sensors 36.

ねじ軸３２の回転に伴ってナット部材３５が前後方向Ｙに沿って移動すると、ナット部材３５に設けられた被検知部５２の先端部５２Ｂが、それぞれのセンサ３６の溝３６Ａを通過する。先端部５２Ｂが溝３６Ａに嵌まった状態では、この溝３６Ａにおける検知光が先端部５２Ｂによって遮られる。 When the nut member 35 moves along the front-rear direction Y with the rotation of the screw shaft 32, the tip portion 52B of the detected portion 52 provided on the nut member 35 passes through the groove 36A of each sensor 36. When the tip portion 52B is fitted in the groove 36A, the detection light in the groove 36A is blocked by the tip portion 52B.

図４に示すように被検知部５２の先端部５２Ｂが最も後側Ｙ２のセンサ３６の溝３６Ａに嵌まった状態では、前述したロック部１８が、最も上側Ｚ１かつ最も前側Ｙ１の凹部６Ｃと回動方向Ｋにおいて同じ位置にあり、洗濯槽３の回動角度θが６０度である（図１参照）。一方、被検知部５２の先端部５２Ｂが最も前側Ｙ１のセンサ３６の溝３６Ａに嵌まった状態では、ロック部１８が、図１における最も後側Ｙ２の凹部６Ｃと回動方向Ｋにおいて同じ位置にあり、洗濯槽３の回動角度θが５度である。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５２の先端部５２Ｂは、いずれか１つのセンサ３６の溝３６Ａに嵌まった状態になる。そのため、５つのセンサ３６のまとまりは、ナット部材３５の被検知部５２を非接触で検知することによって、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。 As shown in FIG. 4, when the tip portion 52B of the detected portion 52 is fitted into the groove 36A of the sensor 36 on the rearmost side Y2, the lock portion 18 described above is the recess 6C of the uppermost Z1 and the frontmost side Y1. They are at the same position in the rotation direction K, and the rotation angle θ of the washing tub 3 is 60 degrees (see FIG. 1). On the other hand, when the tip portion 52B of the detected portion 52 is fitted in the groove 36A of the sensor 36 on the frontmost side Y1, the lock portion 18 is at the same position as the recess 6C on the rearmost side Y2 in FIG. 1 in the rotation direction K. The rotation angle θ of the washing tub 3 is 5 degrees. When the rotation angle θ is any of 5 degrees, 15 degrees, 30 degrees, 45 degrees, and 60 degrees, the tip portion 52B of the detected portion 52 is fitted in the groove 36A of any one of the sensors 36. become. Therefore, the group of the five sensors 36 has a rotation angle θ of 5 degrees, 15 degrees, 30 degrees, 45 degrees, or 60 degrees by detecting the detected portion 52 of the nut member 35 in a non-contact manner. Is detected.

図５は、左側Ｘ１の支持部材１３および駆動機構８の左側面図であり、図６は、図５のＡ−Ａ矢視断面図である。図６では、説明の便宜上、前側折曲部１３Ｇが破線で図示される。図６を参照して、駆動機構８では、連結部５１の第２部５１Ｂが左側Ｘ１の支持部材１３よりも左側Ｘ１へはみ出して配置されるが、駆動機構８のほぼ全体は、左側Ｘ１の支持部材１３の内側、つまり、この支持部材１３と洗濯槽３との間に配置される。詳しくは、駆動機構８において第２部５１Ｂ以外のほとんどの部分は、前後方向Ｙから見たときにおける左側Ｘ１の支持部材１３の前側折曲部１３Ｇおよび後側折曲部１３Ｈの輪郭の内側に収まるように配置される。このように、駆動機構８が、支持部材１３の外側へはみ出して配置されるのではなく、支持部材１３と洗濯槽３との間に配置されるので、左右方向Ｘにおける洗濯機１の小型化を図れる。これにより、洗濯機１の設置スペースの省スペース化を図れる。 FIG. 5 is a left side view of the support member 13 and the drive mechanism 8 on the left side X1, and FIG. 6 is a cross-sectional view taken along the line AA of FIG. In FIG. 6, for convenience of explanation, the front bent portion 13G is shown by a broken line. With reference to FIG. 6, in the drive mechanism 8, the second portion 51B of the connecting portion 51 is arranged so as to protrude from the support member 13 of the left side X1 to the left side X1, but almost the entire drive mechanism 8 is arranged on the left side X1. It is arranged inside the support member 13, that is, between the support member 13 and the washing tub 3. Specifically, in the drive mechanism 8, most of the parts other than the second part 51B are inside the contours of the front bent portion 13G and the rear bent portion 13H of the support member 13 on the left side X1 when viewed from the front-rear direction Y. Arranged to fit. In this way, the drive mechanism 8 is not arranged so as to protrude to the outside of the support member 13, but is arranged between the support member 13 and the washing tub 3, so that the washing machine 1 can be downsized in the left-right direction X. Can be planned. As a result, the installation space of the washing machine 1 can be saved.

図７は、変形例に係る洗濯機１を下側Ｚ２から見た斜視図である。支持フレーム４は、前述した実施形態では、一対の支持部材１３と、これらの支持部材１３間に架設される柱状のビーム部材１４とを含む（図３参照）。これに代え、支持フレーム４は、図７に示すように、一対の支持部材１３と、これらの支持部材１３の下端部間に架設される平板状の底部材６０とを一体的に有するＵ字状の一体物であってもよい。一体物の支持フレーム４では、それぞれの支持部材１３における剛性の向上を図れるし、支持フレーム４全体での剛性の向上も図れる。そのため、一対の支持部材１３間での捩れを抑制できるので、この捩れによって洗濯槽３の回動軸１２に負担がかかることを抑制できる。 FIG. 7 is a perspective view of the washing machine 1 according to the modified example as viewed from the lower side Z2. In the above-described embodiment, the support frame 4 includes a pair of support members 13 and a columnar beam member 14 erected between the support members 13 (see FIG. 3). Instead of this, as shown in FIG. 7, the support frame 4 has a U-shape integrally having a pair of support members 13 and a flat plate-shaped bottom member 60 erected between the lower ends of these support members 13. It may be an integral part of the shape. In the integrated support frame 4, the rigidity of each support member 13 can be improved, and the rigidity of the entire support frame 4 can also be improved. Therefore, since the twist between the pair of support members 13 can be suppressed, it is possible to suppress the load on the rotating shaft 12 of the washing tub 3 due to this twist.

この発明は、以上に説明した実施形態に限定されるものではなく、請求項記載の範囲内において種々の変更が可能である。 The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims.

また、モータ３３の駆動が停止したときに前後方向Ｙにおけるナット部材３５の移動、つまり、洗濯槽３の回動を規制できるのであれば、ロック解除機構７や、回動部６の凹部６Ｃを省略してもよい。これにより、回動角度θを無段階で調整できる。 Further, if the movement of the nut member 35 in the front-rear direction Y, that is, the rotation of the washing tub 3 can be regulated when the drive of the motor 33 is stopped, the lock release mechanism 7 and the recess 6C of the rotating portion 6 can be used. It may be omitted. As a result, the rotation angle θ can be adjusted steplessly.
