Yes.
JP 2000-237491 A (FIGS. 12 and 13)

そして、その下部支持部４の挿通孔４ａには、吊り棒５の下部が挿通されている。吊り棒５の下端部には、ワッシャワイヤ６を介してスプリング受け部材７が抜け止め状態に装着されており、その上方に、下から順に、圧縮コイルばねから成るスプリング８、ダンパケース９、ゴム製のダンパ部材１０、及び下部受け部材１１が、それぞれ吊り棒５に挿通された状態で装着され、その最上部に位置する下部受け部材１１が、前記下部支持部４の下面に下方から摺動可能に当接するようになっている。又、ダンパ部材１０の内周面と、これに対応する吊り棒５の下部外周面との間には、潤滑剤であるグリス１２が介在されている。 The lower part of the suspension bar 5 is inserted through the insertion hole 4 a of the lower support part 4. A spring receiving member 7 is attached to the lower end portion of the suspension bar 5 via a washer wire 6 so as to prevent it from coming off. A spring 8, a damper case 9 and a rubber made of a compression coil spring are disposed above the spring receiving member 7 in order from the bottom. The made damper member 10 and the lower receiving member 11 are mounted in a state of being inserted through the suspension rods 5 respectively, and the lower receiving member 11 located at the uppermost part slides on the lower surface of the lower support portion 4 from below. It comes into contact with each other as possible. Further, grease 12 as a lubricant is interposed between the inner peripheral surface of the damper member 10 and the lower outer peripheral surface of the suspension bar 5 corresponding thereto.

他方、吊り棒５の上端部には半球状の上部受け部材１３が装着されており、この上部受け部材１３が前記支持板２の球面凹部２ａに摺動可能に当接して支持され、球面軸受けとなるようになっている。そして、それら、吊り棒５と、上部受け部材１３、下部受け部材１１、ダンパ部材１０、ダンパケース９、スプリング８、スプリング受け部材７、ワッシャワイヤ６、並びにグリス１２により吊下げ手段１４が構成され、４組の吊下げ手段１４により、水槽３が外箱１に上下動可能に吊持されている。 On the other hand, a hemispherical upper receiving member 13 is attached to the upper end portion of the suspension bar 5, and this upper receiving member 13 is slidably contacted and supported by the spherical concave portion 2 a of the support plate 2. It comes to become. The suspension rod 5, the upper receiving member 13, the lower receiving member 11, the damper member 10, the damper case 9, the spring 8, the spring receiving member 7, the washer wire 6, and the grease 12 constitute a suspension means 14. The water tank 3 is suspended by the four sets of suspending means 14 so as to be movable up and down on the outer box 1.

そして、洗濯行程や脱水行程では洗濯物である衣類の洗濯兼脱水槽内での片寄りによるアンバランスによって、洗濯兼脱水槽や水槽に大きな振動が発生するが、吊り棒によってこの振動が外箱に伝わらないようにしている。 In the washing process and dehydration process, a large vibration is generated in the washing / dehydrating tank and the water tank due to imbalance due to the garment that is the laundry in the washing / dehydrating tank. I am trying not to communicate with you.

吊り棒５の上端部の上部受け部材１３と下部受け部材１１とは共に固定して設けられているものであり、その結果、吊り棒５の吊下げ長さは一定である。 The upper receiving member 13 and the lower receiving member 11 at the upper end of the suspension bar 5 are both fixedly provided. As a result, the suspension length of the suspension bar 5 is constant.

洗濯兼脱水槽の形状は鉛直方向に長い円筒型で、かつ、洗濯兼脱水槽の回転中心軸が鉛直方向を向いているように水槽を鉛直に支承する場合はこのような吊下げ長さは一定の吊り棒５が適している。反面、水槽を前方に向かって斜めに傾斜させるように支承するには適していない。 The shape of the washing / dehydrating tub is a cylindrical shape that is long in the vertical direction, and when the water tub is supported vertically so that the rotation center axis of the washing / dehydrating tub faces the vertical direction, the hanging length is A certain hanging rod 5 is suitable. On the other hand, it is not suitable for supporting the water tank so as to be inclined obliquely toward the front.

一方、洗濯兼脱水槽や水槽が鉛直方向を向いているのでは、洗濯乾燥時において衣類の鉛直方向への回転移動が少なくなる傾向にあり、その結果、衣類が洗濯兼脱水槽内で上下方向に入れ替りにくくなって、衣類に皺が生じたり、乾燥ムラが生じたりしやすかった。 On the other hand, if the washing / dehydration tub or water tank is oriented vertically, there is a tendency for the rotational movement of the clothes to be less during washing and drying, and as a result, the clothes are moved vertically in the washing / dehydration tank. It was difficult to change the clothes, and it was easy for wrinkles to occur and uneven drying.

また、洗い行程でも、ほとんどが水平方向の単純な水流であり、洗浄効果が十分ではなかった。 In addition, most of the washing process was a simple horizontal water flow, and the washing effect was not sufficient.

さらに、洗濯兼脱水槽が長い円筒型であるため、このような形状の槽が垂直に配設されていると、槽内の衣類を取出す際、特に底部のものを取出しにくく、使い勝手がよくなかった。 Furthermore, since the washing and dewatering tub is a long cylindrical shape, when the tub with such a shape is arranged vertically, it is difficult to take out the bottom of the garment in the tub. It was.

本発明は前記従来例の不都合を解消するものとして、水槽を簡単かつ確実に斜めに吊下げ支承でき、その結果、乾燥行程時には洗濯兼脱水槽内の衣類が上下方向に入れ替りやすく、衣類に皺が生じたり、乾燥ムラが発生することを防止でき、また、洗い行程では水流を複雑にできてより一層の洗浄効果が期待でき、さらに洗濯兼脱水槽内からの衣類の取出し作業を行いやすくできる洗濯機を提供することを目的とする。 The present invention eliminates the inconvenience of the conventional example, and can easily and reliably suspend and support the water tank. As a result, the clothes in the washing and dewatering tank can be easily changed in the vertical direction during the drying process. And the occurrence of drying unevenness can be prevented, the water flow can be complicated in the washing process, and a further washing effect can be expected, and the clothes can be easily taken out from the washing / dehydrating tank. The purpose is to provide a washing machine.

本発明は前記目的を達成するものとして、外箱内にその四隅から吊下げ手段によって水槽を吊下げ、底部に攪拌翼を配設した洗濯兼脱水槽を前記水槽内に配設し、洗濯兼脱水槽の下方にギヤ、クラッチなどの機構を介してモータを配設した洗濯機において、前記吊り下げ手段は、一つの吊り下げ手段に相対し組み込まれる駆動ユニットによって、駆動されることを特徴とする。 In order to achieve the above object, the present invention provides a washing / dehydration tub in which a water tub is suspended from the four corners of the outer box by means of suspending and a stirring blade is disposed at the bottom in the water tub. In a washing machine in which a motor is disposed below a dewatering tub via a mechanism such as a gear and a clutch, the suspension means is driven by a drive unit that is incorporated so as to face one suspension means. To do.

水槽は、外箱内で四隅のうちの全部または一部を吊下げ長さを調整可能とした吊り棒による吊下げ手段を介して外箱から吊下げられるから、この吊下げ長さを変えることで外箱内で水槽を前側が低くなるように傾斜させて吊り支承できる。よって、洗濯兼脱水槽の回転中心軸が鉛直方向ではなく、斜め方向となるから、乾燥行程時には洗濯兼脱水槽内の衣類が鉛直方向に回転移動しやすくなり、皺の発生や乾燥ムラを抑えることができる。
また、駆動ユニットは、吊り棒に相対し組み込んでいるため、一つの駆動ユニットで複数の吊り棒を駆動させる場合に比べて、電力量の小さい電源で駆動させることができる。 Since the aquarium is suspended from the outer box by means of a suspension bar that allows the suspension length to be adjusted at all or part of the four corners in the outer box, the suspension length can be changed. In the outer box, the water tank can be suspended and supported so that the front side is lowered. Therefore, the center axis of rotation of the washing / dehydrating tub is not in the vertical direction, but in an oblique direction, so that the clothes in the washing / dehydrating tub can be easily rotated in the vertical direction during the drying process, and generation of wrinkles and drying unevenness is suppressed. be able to.
Moreover, since the drive unit is incorporated in opposition to the suspension rod, the drive unit can be driven by a power source having a small amount of electric power compared to a case where a plurality of suspension rods are driven by one drive unit.

また、洗い行程でも洗濯兼脱水槽の回転中心軸が斜め方向となることで、水流が複雑となって洗浄効果が増大する。 In addition, since the rotation center axis of the washing / dehydrating tank is inclined in the washing process, the water flow becomes complicated and the washing effect is increased.

さらに、水槽を手前に傾斜させることで、洗濯兼脱水槽内の衣類を取出す際に槽の上部開口面が使用者の方に斜めに向き、洗濯兼脱水槽の手前の高さが低くなる。これにより、槽内を見やすくなって、衣類の取出し作業が行いやすくなる。 Further, by tilting the water tank forward, the upper opening surface of the tank faces obliquely toward the user when taking out the clothes in the washing / dehydration tank, and the height in front of the washing / dehydration tank is lowered. This makes it easier to see the inside of the tank and facilitates the work of taking out clothes.

なお、吊り棒をネジ結合はある程度の結合長さを確保できるので、吊り棒を斜めにして水槽を吊り支承する場合にも、吊り棒を斜めにした状態で上部をしっかりと支えることができる。 In addition, since a certain amount of coupling length can be secured when the suspension rod is screw-coupled, the upper portion can be firmly supported with the suspension rod tilted even when the suspension rod is slanted and the water tank is suspended and supported.

以下、図面について本発明の実施形態を詳細に説明する。図１は本発明の洗濯機の第１実施形態を示す側面側の説明図、図２は同上平面側の説明図、図３は同上要部である吊下げ手段の正面図で、洗濯機の全体構成は既に説明したとおり、洗濯機は外箱１内にその四隅から吊下げ手段１４によって水槽３を吊下げ、図示は省略するが底部に攪拌翼を配設した洗濯兼脱水槽を前記水槽内に配設し、洗濯兼脱水槽の下方にギヤ、クラッチなどの機構を介してモータ３３を配設している。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view illustrating a first embodiment of the washing machine according to the present invention, FIG. 2 is a side view illustrating the same, and FIG. 3 is a front view of a hanging means which is a main part of the washing machine. As already described, the washing machine suspends the water tub 3 from the four corners of the washing machine 1 by means of suspending means 14 in the outer box 1, and although not shown, the washing and dewatering tub provided with a stirring blade at the bottom is the water tub. A motor 33 is disposed below the washing and dewatering tub via a mechanism such as a gear and a clutch.

本発明は前記吊下げ手段１４として、図３に示すように、下部に防振部分１５を組み込んだ吊り棒５の上部に雄ネジ１６の部分を形成し、この雄ネジ１６の部分を雌ネジ回転体１８にネジ込んで吊下げ長さを調整可能とした。 In the present invention, as the suspending means 14, as shown in FIG. 3, a male screw 16 part is formed on the upper part of the suspension bar 5 incorporating a vibration-proof part 15 at the lower part, and this male screw 16 part is formed into a female screw. The hanging length can be adjusted by screwing into the rotating body 18.

合成樹脂製の外周ネジ管による雄ネジ１６は、吊り棒５の本体とインサート成形で製作を行うことになるが、その場合にはインサート成形時の熱収縮や、使用時の雰囲気温度による熱収縮（洗濯乾燥機では乾燥時の温度が７０℃となる）を緩和させる工夫が必要となる。 The male screw 16 made of a synthetic resin outer peripheral screw tube is manufactured by insert molding with the main body of the suspension bar 5. In that case, heat shrinkage at the time of insert molding or heat shrinkage due to the ambient temperature during use. It is necessary to devise a measure to alleviate (the temperature at the time of drying is 70 ° C. in a washing dryer).

そこで本発明は、図５に示すように外周ネジ管による雄ネジ１６を長さ方向に分割するか、またはネジ１６ａのピッチ以下の幅のスリット２３を間隔を存して形成してこのような熱収縮に対応させる。 Therefore, in the present invention, as shown in FIG. 5, the male screw 16 by the outer peripheral screw tube is divided in the length direction, or slits 23 having a width equal to or smaller than the pitch of the screw 16a are formed at intervals. Correspond to heat shrinkage.

前記雌ネジ回転体１８はこれを外箱１の内側に突出させたフランジ状の吊り板２４に固定的にも設けてもよいが、下方に球面座を設け、これを外箱１の吊り板２４の球形凹部（図示せず）に係合させる。 The female screw rotating body 18 may be fixedly provided on a flange-like suspension plate 24 projecting from the inside of the outer box 1, but a spherical seat is provided below, and this is attached to the suspension plate of the outer box 1. Engage with 24 spherical recesses (not shown).

防振部分１５は前記図１１、図１２に示した従来例と同じものでもよいが、他の従来例として、図１０に示すように、上部バネ受け２９と下部バネ受け３０間にバネ２７を配し、バネ２７の外周に弾性部材３１を嵌めたものでもよい。図中２８はゴムスプリングである。 The vibration isolating portion 15 may be the same as the conventional example shown in FIGS. 11 and 12, but as another conventional example, a spring 27 is provided between the upper spring receiver 29 and the lower spring receiver 30 as shown in FIG. The elastic member 31 may be fitted on the outer periphery of the spring 27. In the figure, 28 is a rubber spring.

弾性部材３１はゴム部材によるものであり、これによりバネ部材の鋼線とゴム部材とを摩擦摺動させ、振動を減衰させることで、脱水行程時の振動を抑える。 The elastic member 31 is made of a rubber member. By this, the steel wire of the spring member and the rubber member are frictionally slid to attenuate the vibration, thereby suppressing the vibration during the dehydration process.

防振部分１５は、水槽３の側部から側方に突出させたフランジ２５に係止する。これにより、吊下げ手段１４が外箱１と水槽３との間に懸架される。 The vibration isolating portion 15 is locked to a flange 25 that protrudes laterally from the side of the water tank 3. Thereby, the suspending means 14 is suspended between the outer case 1 and the water tank 3.

本発明の雄ネジ１６の部分を雌ネジ回転体１８にネジ込んで吊下げ長さを調整可能とした吊下げ手段１４は外箱１内の四隅に配置されるが、四隅の全てに本発明の構成による吊下げ手段１４を配置する必要はなく、少なくとも後方のコーナー部２箇所に設け、前側２箇所は球面座２６による従来形の吊り棒５（図１０参照）による吊下げ手段１４としてもよい。 The suspending means 14 capable of adjusting the suspending length by screwing the male screw 16 portion of the present invention into the female screw rotating body 18 is arranged at the four corners in the outer box 1. It is not necessary to arrange the suspending means 14 having the structure described above, and the suspension means 14 is provided at least at the two corners on the rear side, and the two front sides are also used as the suspending means 14 by the conventional suspension rod 5 (see FIG. 10) by the spherical seat 26. Good.

次に動作について説明する。本発明の雄ネジ１６の部分を雌ネジ回転体１８にネジ込んでなる吊下げ手段１４は、雌ネジ回転体１８を回転することにより吊り棒５を雄ネジ１６を介して上下動でき、これにより吊り棒５の長さを調整できる。 Next, the operation will be described. The suspension means 14 in which the male screw 16 portion of the present invention is screwed into the female screw rotating body 18 can move the suspension bar 5 up and down via the male screw 16 by rotating the female screw rotating body 18. Thus, the length of the suspension bar 5 can be adjusted.

このようにして後部に配置した吊り棒５を短くすれば、水槽３の後部が持ちあがる。なお。前側には球面座２６による従来形の吊り棒５があるが、この球面座２６が傾斜の支点となる。 If the suspension rod 5 arranged at the rear part is shortened in this way, the rear part of the water tank 3 is lifted. Note that. On the front side, there is a conventional suspension rod 5 with a spherical seat 26. This spherical seat 26 serves as a tilting fulcrum.

その結果、水槽３は前方に向かって斜めに傾斜しているから、洗濯兼脱水槽内の衣類は効率よく上下方向に入れ替り、乾燥効率が向上する。また、洗い行程時にも水槽３を傾斜させることで、水流の方向が複雑になり、洗浄効果が増大する。 As a result, since the water tank 3 is inclined obliquely toward the front, the clothes in the washing and dewatering tank are efficiently switched in the vertical direction, and the drying efficiency is improved. In addition, by inclining the water tank 3 during the washing process, the direction of the water flow becomes complicated and the washing effect increases.

さらに、洗濯終了時に洗濯兼脱水槽内から衣類を取出す際にも、水槽３を手前に傾斜しているので、洗濯兼脱水槽の上部開口の手前側が低位置となると同時に洗濯兼脱水槽内が見やすくなり、衣類の取出し作業が行いやすくなる。 Further, when the clothes are taken out from the washing / dehydrating tub at the end of the washing, the water tub 3 is inclined toward the front, so that the front side of the upper opening of the washing / dehydrating tub is at a low position and at the same time, It becomes easier to see and clothes can be taken out easily.

第２実施形態として、図示は省略するが、本発明の雄ネジ１６の部分を雌ネジ回転体１８にネジ込んでなる吊下げ手段１４は、これを少なくとも前方のコーナー部２箇所に設け、後ろ側２箇所は図１０に示す球面座２６による従来形の吊り棒５による吊下げ手段１４としてもよい。 Although not shown in the drawings as the second embodiment, the suspending means 14 in which the portion of the male screw 16 of the present invention is screwed into the female screw rotating body 18 is provided at at least two front corners, and the rear. The two places on the side may be the suspension means 14 by the conventional suspension rod 5 by the spherical seat 26 shown in FIG.

この場合は、前部に配置した吊り棒５を長くすれば、水槽３は前方に向かって斜めに傾斜する。 In this case, if the suspension bar 5 arranged at the front is lengthened, the water tank 3 is inclined obliquely toward the front.

さらに、本発明の第３実施形態として、図４に示すように、雌ネジ回転体１８を回転体とし、これを駆動部１７で回転駆動することにより、吊下げ長さを自動調整可能とすることもできる。 Furthermore, as a third embodiment of the present invention, as shown in FIG. 4, the female screw rotating body 18 is a rotating body, and this is rotationally driven by a drive unit 17, so that the suspension length can be automatically adjusted. You can also.

駆動部１７はＤＣモータによるもの、雌ネジ回転体１８はこのモータに歯合する嵌合歯車による。これら駆動部１７と雌ネジ回転体１８とで駆動ユニット（アクチュエーター）１９が形成され、吊り棒５の上部にこれが一体物として組み込まれる。 The drive unit 17 is based on a DC motor, and the female screw rotating body 18 is based on a fitting gear meshing with the motor. A drive unit (actuator) 19 is formed by the drive unit 17 and the female screw rotating body 18, and this is incorporated as an integral part on the upper part of the suspension bar 5.

図中２０、２１は駆動ユニット（アクチュエーター）１９の上下位置で吊り棒５の駆動部分を埃や水分から保護する密閉ケースとしての防塵ケース、２２は駆動ユニット（アクチュエーター）１９の下面に形成する球面座である。 In the figure, reference numerals 20 and 21 denote dust-proof cases as a sealed case for protecting the drive portion of the suspension bar 5 from dust and moisture at the upper and lower positions of the drive unit (actuator) 19, and 22 a spherical surface formed on the lower surface of the drive unit (actuator) 19. The seat.

前記雌ネジ回転体１８はこれを合成樹脂とした場合は、少なくとも嵌合部である歯部分は金属とし、インサートで形成する。この嵌合部は摺動材（例えばグリス等）を塗布するか、歯車のインサート部分をポーラス状の金属として、その中に摺動材を含油させて自動注入させることができるものとする。 When the female screw rotating body 18 is made of a synthetic resin, at least a tooth portion as a fitting portion is made of metal and is formed by an insert. This fitting portion can be applied with a sliding material (for example, grease) or the insert portion of the gear can be made of a porous metal so that the sliding material can be oiled and injected automatically.

本発明の駆動ユニット（アクチュエーター）１９を組み込んだ吊下げ手段１４は外箱１内の四隅に配置されるが、図８、図９の例は四隅の全てに本発明の構成による吊下げ手段１４を配置する場合である。 The suspending means 14 incorporating the drive unit (actuator) 19 of the present invention is arranged at the four corners in the outer case 1, but the examples of FIGS. 8 and 9 are suspending means 14 according to the configuration of the present invention at all four corners. It is a case where it arranges.

次に動作について説明する。駆動ユニット（アクチュエーター）１９を組み込んだ吊下げ手段１４は、駆動部１７により雌ネジ回転体１８を回転駆動することにより吊り棒５を雄ネジ１６を介して上下動でき、これにより吊り棒５の長さを調整できる。 Next, the operation will be described. The suspension means 14 incorporating the drive unit (actuator) 19 can move the suspension bar 5 up and down via the external thread 16 by rotating the internal thread rotating body 18 by the drive unit 17. The length can be adjusted.

また、吊り棒５は球面座２２を介して洗濯機本体に保持されているため、洗濯・脱水等の運転時に発生する水槽３の円周方向の移動に対してはフレキシブルに稼動できる。よって、雌ネジ回転体１８を駆動させる駆動部１７には駆動以外の余分の負荷（水槽３の荷重・振動）が掛からない構造である。 Further, since the suspension bar 5 is held by the washing machine main body via the spherical seat 22, it can operate flexibly with respect to the circumferential movement of the water tank 3 that occurs during operations such as washing and dehydration. Therefore, the driving unit 17 that drives the female screw rotating body 18 has a structure in which an extra load (load / vibration of the water tank 3) other than driving is not applied.

例えば乾燥行程時や、洗い行程時や、洗濯終了時には、駆動ユニット（アクチュエーター）１９を駆動して後部に配置した吊り棒５を短くすれば、水槽３の後部が持ちあがる。 For example, at the time of the drying process, at the time of the washing process, or at the end of washing, the rear part of the water tank 3 can be lifted by driving the drive unit (actuator) 19 to shorten the suspension rod 5 disposed at the rear part.

その結果、水槽３は前方に向かって斜めに傾斜するから、水槽３内の洗濯兼脱水槽はその回転中心軸が鉛直方向から斜め方向に変換され、洗濯兼脱水槽内の衣類は効率よく上下方向に入れ替り、乾燥効率が向上する。また、洗い行程時には水槽３を傾斜させることで、水流の方向が複雑になり、洗浄効果が増大する。 As a result, the aquarium 3 is inclined obliquely forward, so that the washing / dehydrating tub in the aquarium 3 has its rotation center axis changed from a vertical direction to an oblique direction, and the clothes in the washing / dehydrating tub can be efficiently moved up and down. The direction is changed and the drying efficiency is improved. Further, by inclining the water tank 3 during the washing process, the direction of the water flow becomes complicated, and the washing effect increases.

さらに、洗濯終了時に洗濯兼脱水槽内から衣類を取出す際にも、水槽３を手前に傾斜させれば、洗濯兼脱水槽の上部開口の手前側が低位置となると同時に洗濯兼脱水槽内が見やすくなり、衣類の取出し作業が行いやすくなる。 Furthermore, when clothes are taken out from the washing / dehydrating tub at the end of washing, if the water tub 3 is tilted forward, the front side of the upper opening of the washing / dehydrating tub becomes low and the washing / dehydrating tub is easy to see. This makes it easier to take out clothes.

一方、脱水行程時には、水槽３を水平に位置させ洗濯兼脱水槽の回転中心軸を鉛直方向に保持することで、洗濯兼脱水槽を水平に回転させて遠心力を有効に活用させ脱水効率が低下しないようにする。 On the other hand, during the dehydration process, the water tub 3 is positioned horizontally and the rotation central axis of the washing / dehydrating tub is held in the vertical direction, so that the washing / dehydrating tub is rotated horizontally to effectively utilize the centrifugal force and the dewatering efficiency is improved. Do not drop.
