Description

本発明は、洗濯乾燥機の特に水槽の吊下げ支持手段に関するものである。 The present invention relates to a hanging support means for a washing / drying machine, particularly a water tank.

一般に、洗濯乾燥機は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もので、前記吊下げ手段は、例えばダンパ（バネ部材）を有する吊り棒で構成されており、水槽はこの吊り棒により外箱内でその四隅から揺動自在に懸下されている（例えば特許文献１参照）。 Generally, a washing / drying machine suspends a water tub from its four corners in the outer box by means of suspending, and a washing / dehydration tub with a stirring blade at the bottom is provided in the water tub, below the washing / dehydration tub. A motor is disposed through a mechanism such as a gear and a clutch, and the suspension means is composed of, for example, a suspension rod having a damper (spring member), and the water tank is placed inside the outer box by the suspension rod. It is suspended from four corners so as to be swingable (see, for example, Patent Document 1).

この状態で水槽内には回転中心軸を鉛直方向に有する洗濯兼脱水槽が回転自在に支持される。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。
特開平２００３−３１１０６５号公報（図１） In this state, a washing and dewatering tub having a rotation center axis in the vertical direction is rotatably supported in the water tub. 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.
Japanese Patent Laid-Open No. 2003-311065 (FIG. 1)

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ため、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易かった。 The shape of the washing / dehydrating tub is a cylindrical shape that is long in the vertical direction, and the rotation center axis of the washing / dehydrating tub is oriented in the vertical direction, so that the rotational movement of clothes in the vertical direction tends to decrease during washing and drying. As a result, it was difficult for the clothes to be changed in the vertical direction in the washing and dehydrating tank, and the clothes were easily wrinkled or unevenly dried.

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、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いっそう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乾燥機を提供することを目的とする。 The present invention eliminates the inconvenience of the conventional example, the clothes in the washing and dewatering tub can be easily changed in the vertical direction during the drying process, the clothes can be prevented from wrinkling or drying unevenness, An object of the present invention is to provide a washing / drying machine that can make the water flow complicated in the washing step and can expect a further washing effect, and can easily take out the clothes from the washing and dewatering tank.

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乾燥機において、前記吊下げ手段は、その吊下げ長の少なくとも一部をワイヤやロープなどの可撓性索条により構成し、この可撓性索条を外箱内に配設した巻上げ手段に巻回して吊下げ長を調節自在としたことを特徴とする。 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 the washing / drying machine in which the motor is disposed below the dewatering tank through a mechanism such as a gear and a clutch, the suspension means has at least a part of the suspension length by a flexible cable such as a wire or a rope. This flexible cable is wound around winding means disposed in the outer box so that the hanging length is adjustable.

水槽は、外箱内で四隅のうちの一部を巻上げ手段を介して剛性の少ないワイヤやロープなどの可撓性索条により外箱から吊下げられるから、この可撓性索条を巻き上げることで外箱内で水槽が傾斜する。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。 Since the water tank is suspended from the outer box by a flexible rope such as a wire or a rope having a low rigidity through a winding means, a part of the four corners in the outer box is wound up. The water tank inclines inside the outer box. 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.

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、槽内を見易くなって、衣類の取出し作業が行い易くなる。 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. Thereby, it becomes easy to see the inside of a tank and it becomes easy to take out clothing.

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は本発明の洗濯乾燥機の第１実施形態を示す側面側の説明図、図２は同上第２実施形態の背面側の説明図で、洗濯乾燥機の全体構成は既に説明したとおり、洗濯乾燥機は外箱１内にその四隅から吊下げ手段４によって水槽２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２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３を配設している。図中５は外箱１の上部後方に配設したトップカバーを示す。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of a side surface showing a first embodiment of the washing and drying machine of the present invention, FIG. 2 is an explanatory view of the back side of the second embodiment, and the overall configuration of the washing and drying machine is as described above. The washing / drying machine suspends the water tub 2 from the four corners of the outer box 1 by means of suspending means 4, and a washing / dehydration tub having a stirring blade at the bottom is disposed in the water tub 2, although not shown. A motor 3 is disposed below the washing and dewatering tank via a mechanism such as a gear and a clutch. In the figure, reference numeral 5 denotes a top cover disposed on the upper rear side of the outer box 1.

本発明は外箱１内の四隅に配設される吊下げ手段４の、四隅のうちの一部をワイヤ６やロープなどの可撓性索条を有するもので構成する。図１はその第１実施形態を示し、吊下げ手段４は、水槽２の前側に位置するものについては、従来と同様に吊り棒７とその下部に結合される防振バネ４ａとで構成し、吊り棒７の上部を支持片を介して外箱１に係止し、防振バネ４ａを支持片を介して水槽２に係止する。 In the present invention, a part of the four corners of the suspending means 4 disposed at the four corners in the outer box 1 is constituted by a flexible rope such as a wire 6 or a rope. FIG. 1 shows the first embodiment, and the suspending means 4 is composed of a suspension rod 7 and an anti-vibration spring 4a coupled to the lower portion of the suspension means 4 located on the front side of the water tank 2 as in the prior art. The upper part of the suspension bar 7 is locked to the outer box 1 via the support piece, and the vibration-proof spring 4a is locked to the water tank 2 via the support piece.

水槽２の後側に位置するものについては、水槽２の下方部に支持片を介して係止される防振バネ４ａの上部に吊り棒７を結合し、さらにその上部にワイヤ６を結合した。 For the one located on the rear side of the water tank 2, a suspension rod 7 is coupled to the upper part of the anti-vibration spring 4a that is locked to the lower part of the water tank 2 via a support piece, and the wire 6 is further coupled to the upper part thereof. .

そして、トップカバー５の下方に配設したアクチュエータなどによる巻上げ手段８に前記ワイヤ６を巻回する。これにより、水槽２は後方の吊下げ手段４によって後部が懸架長調節自在に吊下げられる。 Then, the wire 6 is wound around the winding means 8 using an actuator or the like disposed below the top cover 5. Thereby, the rear part of the water tank 2 is suspended by the rear suspension means 4 so that the suspension length can be adjusted.

次に動作について説明する。例えば乾燥行程時には、後部に配設してある巻上げ手段８を駆動して、これに巻回してあるワイヤ６を巻き上げれば、水槽２を懸架しているワイヤ６の長さが短くなり、水槽２の後部が持ちあがる。 Next, the operation will be described. For example, during the drying process, if the winding means 8 disposed at the rear portion is driven and the wire 6 wound around the winding means 8 is wound up, the length of the wire 6 that suspends the water tank 2 is shortened. 2 rear part lifts up.

その結果、水槽２は前方に向って斜めに傾斜するから、水槽２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。 As a result, since the water tank 2 is inclined obliquely toward the front, the washing / dehydration tank in the water tank 2 has its rotation center axis changed from the vertical direction to the oblique direction, and the clothes in the washing / dehydration tank can be efficiently moved up and down. The direction is changed and the drying efficiency is improved.

また、洗い行程時にも水槽２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。 Further, by inclining the water tank 2 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２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易くなる。 Furthermore, when clothes are taken out from the washing / dehydrating tub at the end of washing, if the water tub 2 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. It becomes easy to take out clothes.

一方、脱水行程時には、水槽２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 2 is positioned horizontally and the rotation center 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.

図２は第２実施形態を示し、ワイヤ６を用いる吊下げ手段４を水槽２の左右に位置させる。そして、一方の吊下げ手段（図示の例では右側）のワイヤ６をアクチュエータなどの巻上げ手段８から水平に引出して滑車に巻回した後、下方に垂下させて先端の防振バネ４ａを支持片を介して水槽２の下方部に係止して駆動側とし、巻上げ手段８を駆動すると水槽２の一方の側が吊上げられて水槽２の重心が移動する。 FIG. 2 shows a second embodiment in which the suspension means 4 using the wire 6 is positioned on the left and right of the water tank 2. Then, the wire 6 of one suspending means (right side in the illustrated example) is pulled out horizontally from the winding means 8 such as an actuator, wound around the pulley, and then hung downward to support the vibration-proof spring 4a at the tip. When the hoisting means 8 is driven, one side of the water tank 2 is lifted and the center of gravity of the water tank 2 moves.

これに追随して他方の側のワイヤ６で懸架された側がバランスをとるようにして動き水槽２が傾斜する。この左右吊り方式は、重心移動が少ないため、巻上げ手段８の駆動荷重を軽減できる。一方、前記した前後吊り方式は巻上げ手段８の駆動荷重は大きいが、水槽２の移動範囲を小さくでき、省スペース化が図れる。 Following this, the water tank 2 is inclined so that the side suspended by the wire 6 on the other side is balanced. This left and right suspension system can reduce the driving load of the winding means 8 because the center of gravity moves little. On the other hand, although the above-described front / rear suspension system has a large driving load of the hoisting means 8, the moving range of the water tank 2 can be reduced and space saving can be achieved.

なお、本発明の吊下げ手段４は、前記のように吊り棒７にワイヤ６を結合するものであるが、結合手段としては、第１例として図３のように接続金具９を使用してワイヤ６の下部をボルト１０で接続金具９に挟み込んで結合し、吊り棒７の上部をねじ部１１に形成し、このねじ部１１を接続金具９に形成したねじ孔に螺合する。 The suspending means 4 of the present invention joins the wire 6 to the suspension rod 7 as described above. As the joining means, a connecting metal 9 is used as shown in FIG. 3 as a first example. The lower part of the wire 6 is sandwiched and joined to the connection fitting 9 by a bolt 10, the upper part of the suspension rod 7 is formed in the screw portion 11, and this screw portion 11 is screwed into the screw hole formed in the connection fitting 9.

または、第２例として図４に示すように接続金具９の吊り棒７との結合部について、係止孔１２を形成するとともに、吊り棒７の上端をフック部７ａに形成し、この係止孔１２にフック部７ａを掛止することで、接続金具９を介して吊り棒７とワイヤ６とを結合することもできる。 Alternatively, as a second example, as shown in FIG. 4, a locking hole 12 is formed in the joint portion of the connection fitting 9 with the suspension rod 7, and an upper end of the suspension rod 7 is formed in the hook portion 7 a. By hooking the hook portion 7 a in the hole 12, the suspension rod 7 and the wire 6 can be coupled via the connection fitting 9.

さらに、第３例として図５に示すように接続金具を使用せず、ワイヤ６の下部もフック部６ａに形成し、このフック部６ａと吊り棒７のフック部７ａを直接絡み合わせて接続することもできる。 Furthermore, as shown in FIG. 5, as a third example, no connection fitting is used, the lower part of the wire 6 is also formed on the hook part 6a, and the hook part 6a and the hook part 7a of the suspension rod 7 are directly entangled and connected. You can also.
