以下、第１の実施形態につき、図１ないし図１２を参照して説明する。
まず、図３には、洗濯機、特には二槽式洗濯機の外観を示しており、下部に基台１を有し、上部に槽ユニット２を有している。槽ユニット２は、図４に示すように、左側が洗濯槽２ａ、右側が脱水槽２ｂとなっており、洗濯槽２ａの前壁部、左側壁部、及び後壁部と、脱水槽２ｂの前壁部、右側壁部、及び後壁部とが一体に連なって筐体を構成している。又、洗濯槽２ａの右側壁部と脱水槽２ｂの左側壁部は共通となっていて、両槽間の仕切壁となっている。 The first embodiment will be described below with reference to FIGS.
First, FIG. 3 shows the appearance of a washing machine, in particular, a two-tub washing machine, which has a base 1 at the bottom and a tank unit 2 at the top. As shown in FIG. 4, the tub unit 2 has a washing tub 2a on the left side and a dehydration tub 2b on the right side. The front wall, left side wall, and rear wall of the tub 2a, and the dehydration tub 2b The front wall portion, the right side wall portion, and the rear wall portion are integrally connected to form a housing. Further, the right side wall portion of the washing tub 2a and the left side wall portion of the dewatering tub 2b are common, and serve as a partition wall between the two tubs.

洗濯槽２ａの奥側の一隅所には、溢水ストレーナ３を装着しており、洗濯槽２ａの内下部に撹拌体４を回転可能に配設している。撹拌体４は円盤状で、上面に複数の撹拌突起４ａを有している。洗濯槽２ａの底部には、撹拌体４の下方に位置する部分に排水口５を形成しており、この排水口５には、排水弁６を介して、図示しない排水ホースを連ねている。排水ホースは、先端部が機外に臨んでおり、中間部に、図示しない溢水管を介して前記溢水ストレーナ３が覆った図示しない溢水口を接続している。   An overflow strainer 3 is mounted at one corner on the back side of the washing tub 2a, and the agitator 4 is rotatably disposed inside and below the washing tub 2a. The stirring body 4 has a disk shape and has a plurality of stirring protrusions 4a on the upper surface. At the bottom of the washing tub 2 a, a drain port 5 is formed in a portion located below the stirring body 4, and a drain hose (not shown) is connected to the drain port 5 via a drain valve 6. The drainage hose has a front end facing the outside of the machine, and an overflow port (not shown) covered by the overflow strainer 3 is connected to an intermediate part via an overflow pipe (not shown).

洗濯槽２ａの外下面部には軸受機構７を設けており、この軸受機構７で支承した軸７ａの上端部を、洗濯槽２ａの底部を水密且つ回転可能に貫通させて洗濯槽２ａの内下部に突出させ、その突出部分に前記撹拌体４をねじ８により取付けている。
一方、軸受機構７で支承した軸７ａの下端部には、洗濯槽２ａの下方に位置させて従動プーリ９を取付けており、他方、洗濯槽２ａ外下方の、従動プーリ９からやゝ離間した位置には洗濯用モータ１０を配設していて、この洗濯用モータ１０の回転軸１０ａに取付けた駆動プーリ１１と従動プーリ９との間に伝動ベルト１２を張架している。 A bearing mechanism 7 is provided on the outer bottom surface of the washing tub 2a, and the upper end of the shaft 7a supported by the bearing mechanism 7 is penetrated through the bottom of the washing tub 2a in a watertight and rotatable manner. The stirrer 4 is attached to the projecting portion with a screw 8.
On the other hand, a driven pulley 9 is attached to the lower end portion of the shaft 7a supported by the bearing mechanism 7 so as to be positioned below the washing tub 2a. On the other hand, the driven pulley 9 is slightly separated from the driven pulley 9 below the washing tub 2a. A washing motor 10 is disposed at a position, and a transmission belt 12 is stretched between a driving pulley 11 and a driven pulley 9 attached to a rotating shaft 10 a of the washing motor 10.

この結果、撹拌体４は、洗濯用モータ１０により、駆動プーリ１１、伝動ベルト１２、及び従動プーリ９のベルト伝動機構、並びに軸受機構７を順に介して回転駆動、特には時計回りと反時計回りの正逆両方向に交互に低速回転駆動され、その回転により、洗濯槽２ａに収容した図示しない洗濯物を図示しない洗濯水と共に撹拌して洗濯水流を生成し、洗濯をするようになっている。従って、洗濯用モータ１０、駆動プーリ１１、伝動ベルト１２、従動プーリ９のベルト伝動機構、並びに軸受機構７は、撹拌体４を回転駆動する駆動装置Ｋ１を構成するものである。 As a result, the agitator 4 is driven to rotate by the washing motor 10 through the drive pulley 11, the transmission belt 12, the belt transmission mechanism of the driven pulley 9, and the bearing mechanism 7 in this order, particularly clockwise and counterclockwise. Rotating at low speed alternately in both the forward and reverse directions, the laundry (not shown) accommodated in the washing tub 2a is agitated together with the washing water (not shown) to generate a washing water flow, and washing is performed. Accordingly, the washing motor 10, the drive pulley 11, the transmission belt 12, the belt transmission mechanism of the driven pulley 9, and the bearing mechanism 7 constitute a drive device K 1 that rotationally drives the agitator 4.

脱水槽２ｂの内部には、脱水かご１３を回転可能に配設している。脱水かご１３は、周側部に環状の補強リブ１３ａと脱水孔１３ｂをともに多数有するものであり、この脱水かご１３を回転駆動する脱水用モータ１４と、その回転を制止するブレーキ装置１５とを脱水槽２ｂの外下方に配設している。   A dewatering basket 13 is rotatably disposed inside the dewatering tank 2b. The dewatering basket 13 has a large number of annular reinforcing ribs 13a and dewatering holes 13b on the circumferential side, and includes a dehydrating motor 14 that rotationally drives the dewatering basket 13 and a brake device 15 that stops the rotation. It is arranged outside the dehydration tank 2b.

この結果、脱水かご１３は、脱水用モータ１４により直に回転駆動、中でも一方向に高速回転駆動され、その回転により、脱水かご１３内に収容した洗濯物の遠心脱水をするようになっている。従って、脱水用モータ１４は脱水かご１３を回転駆動する駆動装置として機能するものである。なお、脱水槽２ｂにも、底部には排水口１６を形成しており、この排水口１６を図示しない接続管で前記排水ホースの中間部に連ねている。   As a result, the dewatering basket 13 is directly driven to rotate by the dehydrating motor 14, and in particular, is driven to rotate at a high speed in one direction. By the rotation, the laundry stored in the dewatering basket 13 is centrifugally dehydrated. . Accordingly, the dehydrating motor 14 functions as a driving device that rotationally drives the dewatering basket 13. In addition, a drainage port 16 is formed at the bottom of the dehydration tank 2b, and the drainage port 16 is connected to an intermediate portion of the drainage hose through a connection pipe (not shown).

このほか、洗濯槽２ａ及び脱水槽２ｂ上には操作パネル１７を設けており、この操作パネル１７には、洗濯用タイマーの操作つまみ１８と、洗濯用の水流強度切換え及び排水選択用の操作つまみ１９、脱水用タイマーの操作つまみ２０、給水切換え用操作つまみ２１、及び給水ホース接続口２２を設けている。又、洗濯槽２上には蓋２ｃを着脱可能に設け、脱水槽３上には蓋２ｄを開閉可能に軸支して設けている。   In addition, an operation panel 17 is provided on the washing tub 2a and the dewatering tub 2b. The operation panel 17 includes an operation knob 18 for a washing timer, an operation knob for switching water flow strength for washing and selecting drainage. 19, a dewatering timer operation knob 20, a water supply switching operation knob 21, and a water supply hose connection port 22 are provided. A lid 2c is detachably provided on the washing tub 2, and a lid 2d is pivotally supported on the dehydrating tub 3 so as to be opened and closed.

ここで、図５〜図７、図１及び図２は、前記基台１を上方より見て表している。これらの図から明らかなように、基台１の内底面には、モータ取付部２３，２４とモータ取付部２５とをプラスチックによる基台１との一体成形で設けている。そのうち、モータ取付部２３，２４は前記洗濯用モータ１０を選択して取付けるためのものであり、モータ取付部２５は前記脱水用モータ１４を取付けるためのものである。   Here, FIGS. 5 to 7, FIG. 1 and FIG. 2 show the base 1 as viewed from above. As is clear from these drawings, the motor mounting portions 23 and 24 and the motor mounting portion 25 are provided on the inner bottom surface of the base 1 by integral molding with the base 1 made of plastic. Among them, the motor mounting portions 23 and 24 are for selecting and mounting the washing motor 10, and the motor mounting portion 25 is for mounting the dehydrating motor 14.

そして、モータ取付部２３は前記従動プーリ９の右前側に存在し、モータ取付部２４は従動プーリ９を挟んでモータ取付部２３とは対称的に従動プーリ９の左後側に存在している（図１及び図２参照）。換言すれば、モータ取付部２３とモータ取付部２４は、前記撹拌体４の中心位置を挟んで対称的な２箇所に位置しており、更には、前記撹拌体４の中心位置からの方向の異なる複数箇所（この場合、２箇所）に位置しているのである。特に、撹拌体４の中心位置からの方向が異なるのは、モータ取付部２３とモータ取付部２４の各中心位置である。   The motor mounting portion 23 exists on the right front side of the driven pulley 9, and the motor mounting portion 24 exists on the left rear side of the driven pulley 9 symmetrically with the motor mounting portion 23 across the driven pulley 9. (See FIGS. 1 and 2). In other words, the motor mounting portion 23 and the motor mounting portion 24 are located at two symmetrical positions across the center position of the stirring body 4, and further, in the direction from the center position of the stirring body 4. They are located at different places (in this case, two places). In particular, the direction from the center position of the stirrer 4 is different in the center positions of the motor mounting portion 23 and the motor mounting portion 24.

更に、モータ取付部２３は、複数（この場合、３点）の単位取付部２３ａ，２３ｂ，２３ｃから成るもので、モータ取付部２４も、複数（この場合、３点）の単位取付部２４ａ，２４ｂ，２４ｃの３点から成るものであり、いずれも２点の単位取付部２３ａ，２３ｂ、２４ａ，２４ｂが従動プーリ９側（撹拌体４の中心位置に近い側）に位置し、残り１点の単位取付部２３ｃ、２４ｃがそれとは反対側（撹拌体４の中心位置から遠い側）に位置している。   Further, the motor mounting portion 23 is composed of a plurality (in this case, three points) of unit mounting portions 23a, 23b, 23c, and the motor mounting portion 24 is also a plurality of (in this case, three points) unit mounting portions 24a, 24b and 24c are composed of three points, and each of the two unit mounting portions 23a, 23b, 24a and 24b is located on the driven pulley 9 side (side closer to the central position of the stirring member 4), and the remaining one point The unit mounting portions 23c and 24c are located on the opposite side (the side far from the center position of the stirring member 4).

又、そのうちの２点の単位取付部２３ａ，２３ｂ、２４ａ，２４ｂの、それぞれ撹拌体４の中心位置からの距離Ｌ１，Ｌ２（図１参照）の違いで明らかなように、モータ取付部２３，２４は、撹拌体４の中心位置からの距離を異ならせて存在している。詳しくは、モータ取付部２３が、モータ取付部２４より撹拌体４の中心位置から遠くに位置している。 Further, as apparent from the difference in distances L 1 and L 2 (see FIG. 1) of the two unit mounting portions 23a, 23b, 24a, and 24b from the center position of the stirring member 4, respectively, 23 and 24 exist with different distances from the center position of the stirring member 4. Specifically, the motor attachment portion 23 is located farther from the center position of the stirring body 4 than the motor attachment portion 24.

加えて、図８図及び図９に示すように、２点の単位取付部２３ａ，２３ｂ、２４ａ，２４ｂは、基台１の内底面から多段に漸次細く***したほゞ円筒状のもので、その中心部にねじ孔２７，２８を有するものであり、残り１点の単位取付部２３ｃ、２４ｃは、基台１の内底面からほゞ四角筒状に***したもので、その上部に矩形の孔２９、３０を上下に開通させて有し、その孔２９、３０の各両側の部分にそれぞれ２点の単位取付部２３ａ，２３ｂ、２４ａ，２４ｂ方向に列する多数の歯部３１、３２を有している。   In addition, as shown in FIG. 8 and FIG. 9, the two unit mounting portions 23a, 23b, 24a, 24b are substantially cylindrical and gradually raised in a multi-stage from the inner bottom surface of the base 1, The center part has screw holes 27, 28, and the remaining one unit mounting part 23c, 24c is raised from the inner bottom surface of the base 1 in a generally rectangular tube shape, and has a rectangular shape at the top. The holes 29 and 30 are opened up and down, and a large number of tooth portions 31 and 32 arranged in the direction of two unit mounting portions 23a, 23b, 24a and 24b are provided on both sides of the holes 29 and 30, respectively. Have.

この構成で、図１０に示すように、単位取付部２３ａ，２３ｂには、それぞれゴムなど弾性材から成るブッシュ３３を上部に被装し、単位取付部２３ｃには、おなじくゴムなど弾性材から成るブッシュ３５を被装した調整ボス３６を上部に取付けている。調整ボス３６は、図１２に示すように、下部が二股の爪部３６ａとなっており、上部が２段に漸次細く***したほゞ円筒状構成となっていて、その中心部にねじ孔３６ｂを有し、上下部間の中間部の両側下面には歯部３６ｃを有していて、上記単位取付部２３ｃに対しては、爪部３６ａを孔２９に挿入して係合させると共に、歯部３６ｃを歯部３１に係合させることにより、取付けている。   In this configuration, as shown in FIG. 10, the unit mounting portions 23a and 23b are each covered with a bush 33 made of an elastic material such as rubber, and the unit mounting portion 23c is made of an elastic material such as rubber. An adjustment boss 36 covered with a bush 35 is attached to the upper part. As shown in FIG. 12, the adjustment boss 36 has a bifurcated claw portion 36a, and the upper portion has a generally cylindrical configuration in which the upper portion gradually rises in two steps, and a screw hole 36b at the center thereof. And has tooth portions 36c on the lower surfaces of both sides of the intermediate portion between the upper and lower portions. The unit mounting portion 23c is engaged with the claw portion 36a inserted into the hole 29 and the teeth. The part 36c is attached by engaging with the tooth part 31.

なお、歯部３１に対する歯部３６ｃの係合は、その係合位置を変えることで、歯部３１の列した方向に位置変更可能であり、それによって、前記駆動プーリ１１と従動プーリ９との間に張架した伝動ベルト１２の張りを調整できるようになっている。   The engagement of the tooth portion 36c with the tooth portion 31 can be changed in the direction in which the tooth portions 31 are lined up by changing the engagement position thereof, whereby the driving pulley 11 and the driven pulley 9 can be changed. The tension of the transmission belt 12 stretched between them can be adjusted.

そして又、図１０に示すように、ブッシュ３３，３５には、その後に、又はあらかじめ、洗濯用モータ１０の取付フランジ１０ｂを嵌着し、ブッシュ３３の上からワッシャ３７ａを介してねじ３７をねじ孔２７に螺挿して締付け、ブッシュ３５の上からワッシャ３８ａを介してねじ３８をねじ孔３６ｂに螺挿して締付けている。このようにして取付部２３に洗濯用モータ１０を取付けている。   Further, as shown in FIG. 10, the mounting flange 10b of the washing motor 10 is fitted to the bushes 33, 35 thereafter or in advance, and the screw 37 is screwed from above the bush 33 via the washer 37a. The screw is screwed into the hole 27 and tightened, and the screw 38 is screwed into the screw hole 36b through the washer 38a from above the bush 35 and tightened. In this way, the washing motor 10 is attached to the attachment portion 23.

これに代わって、モータ取付部２４に洗濯用モータ１０を取付けるには、図１１に示すように、単位取付部２４ａ，２４ｂに、それぞれゴムなど弾性材から成るブッシュ３９を上部に被装し、単位取付部２４ｃの上部には、おなじくゴムなど弾性材から成るブッシュ４１を被装した調整ボス４２を取付ける。調整ボス４２は、調整ボス３６同様に、下部が二股の爪部４２ａとなっており、上部が２段に漸次細く***したほゞ円筒状構成となっていて、その中心部にねじ孔４２ｂを有し、上下部間の中間部の両側下面には歯部４２ｃを有していて、上記単位取付部２４ｃに対しては、爪部４２ａを孔３０に挿入して係合させると共に、歯部４２ｃを歯部３２に係合させることにより、取付けている。   Instead, in order to attach the washing motor 10 to the motor mounting portion 24, as shown in FIG. 11, the unit mounting portions 24a and 24b are respectively covered with bushes 39 made of an elastic material such as rubber, An adjustment boss 42 covered with a bush 41 made of an elastic material such as rubber is attached to the upper portion of the unit mounting portion 24c. Similar to the adjustment boss 36, the adjustment boss 42 has a bifurcated claw portion 42 a, and the upper portion has a generally cylindrical configuration in which the upper portion gradually rises in two steps. A screw hole 42 b is formed at the center of the adjustment boss 42. And has tooth portions 42c on the lower surfaces of both sides of the intermediate portion between the upper and lower portions. The unit mounting portion 24c is engaged with the claw portion 42a inserted into the hole 30 and the tooth portion. 42c is attached by engaging the tooth part 32.

なお、歯部３２に対する歯部４２ｃの係合も、その係合位置を変えることで、歯部３２の列した方向に位置変更可能である。
そして、ブッシュ３９，４１には、その後に、又はあらかじめ、洗濯用モータ１０の取付フランジ１０ｂを嵌着し、ブッシュ３９の上からワッシャ４３ａを介してねじ４３をねじ孔２８に螺挿して締付け、ブッシュ４１の上からワッシャ４４ａを介してねじ４４をねじ孔４２ｂに螺挿して締付けている。このようにしてモータ取付部２４に洗濯用モータ１０を取付ける。 In addition, the position of the engagement of the tooth part 42c with the tooth part 32 can be changed in the direction in which the tooth parts 32 are arranged by changing the engagement position.
Then, after or in advance, the mounting flange 10b of the washing motor 10 is fitted to the bushes 39, 41, and the screws 43 are screwed into the screw holes 28 from the top of the bushes 39 through the washers 43a, and tightened. A screw 44 is screwed into the screw hole 42b from above the bush 41 through a washer 44a and tightened. In this manner, the washing motor 10 is attached to the motor mounting portion 24.

なお、モータ取付部２４に取付けた洗濯用モータ１０の回転軸１０ａには、前記駆動プーリ１１とは異なる、例えばそれより径大な駆動プーリ４５（図２参照）を取付ける。又、この場合、洗濯槽２ａの外下面部には、前記軸受機構７に代わって、複数のギヤ列を内蔵した減速機（図示せず）を設け、この減速機の上方に突出した出力軸を前記洗濯槽２ａの底部を水密且つ回転可能に貫通させて洗濯槽２ａの内下部に突出させ、その突出部分に前記撹拌体４を取付ける。更に、減速機の下方に突出した入力軸には、前記軸受機構７の軸７ａの下端部に取付けた従動プーリ９に代わって、それとは異なる、例えばそれより径小な従動プーリ４７（図２参照）を取付け、この従動プーリ４７と上記駆動プーリ４５との間に伝動ベルト（図示せず）を張架する。   Note that a drive pulley 45 (see FIG. 2) having a diameter larger than that of the drive pulley 11, for example, is attached to the rotating shaft 10a of the washing motor 10 attached to the motor attachment portion 24. In this case, on the outer bottom surface of the washing tub 2a, a reduction gear (not shown) incorporating a plurality of gear trains is provided in place of the bearing mechanism 7, and an output shaft protruding above the reduction gear is provided. The bottom of the washing tub 2a is penetrated in a watertight and rotatable manner so as to protrude into the inner and lower portions of the washing tub 2a, and the stirring body 4 is attached to the protruding portion. Further, instead of the driven pulley 9 attached to the lower end portion of the shaft 7a of the bearing mechanism 7, the input shaft protruding downward from the speed reducer is different from, for example, a driven pulley 47 having a smaller diameter (FIG. 2). And a transmission belt (not shown) is stretched between the driven pulley 47 and the drive pulley 45.

この結果、この場合には、撹拌体４は、洗濯用モータ１０により、駆動プーリ４５、図示しない伝動ベルト、及び従動プーリ４７のベルト伝動機構、並びに図示しない減速機を順に介して回転駆動されるようになっている。従って、その、洗濯用モータ１０、駆動プーリ４５、伝動ベルト、及び従動プーリ４７のベルト伝動機構、並びに減速機は、撹拌体４を前記駆動装置Ｋ１に代わって回転駆動する駆動装置Ｋ２（図２参照）を構成するようになっている。又、前記モータ取付部２４の単位取付部２４ｃにおける歯部３２に対する調整ボス４２の歯部４２ｃの係合位置が変更可能である点は、それによって、図示しない伝動ベルトの張りが調整できることを意味している。 As a result, in this case, the agitator 4 is rotationally driven by the washing motor 10 through the drive pulley 45, the transmission belt (not shown), the belt transmission mechanism of the driven pulley 47, and the reduction gear (not shown) in this order. It is like that.
