Description

本発明は、洗濯乾燥機の特に水槽の支持手段に関するものである。 The present invention relates to a means for supporting 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).

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２００４−３４４３３８号公報（図１） In the washing process and dehydration process, large vibrations are generated in the washing / dehydrating tub and the water tank due to imbalance due to the misalignment of the laundry clothes in the washing / dehydrating tank. I am trying not to communicate with you.
JP 2004-344338 A (FIG. 1)

洗濯行程時の振動を抑えるために、従来は、例えば弾性（ゴム）部材をバネ部材の外周面に配置し、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、振動を減衰させるようにしているが、吊り棒を使用しているため、ねじり方向への剛性が大きく、攪拌翼回転時の反力などで水槽が回転方向に振動する際に、外箱と水槽との間で振動伝達されるため、外箱振動および騒音が発生するという問題があった。 In order to suppress the vibration during the washing process, conventionally, for example, an elastic (rubber) member is disposed on the outer peripheral surface of the spring member, and thereby the steel wire of the spring member and the rubber member are frictionally slid to attenuate the vibration. However, since the suspension rod is used, the rigidity in the torsional direction is large, and when the aquarium vibrates in the rotation direction due to the reaction force at the time of stirring blade rotation, it is between the outer box and the aquarium. Since vibration is transmitted, there has been a problem that outer box vibration and noise are generated.

また、脱水行程時の振動を抑えるためにも、前記と同様にして弾性（ゴム）部材をバネ部材の外周面に配置し、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、振動を減衰させるようにしているが、吊り棒を使用しているために、上下方向の剛性があり、脱水起動時の傾き振動発生の際に、外箱と水槽との間で振動伝達されるため、外箱振動および騒音が発生するという問題があった。 Also, in order to suppress vibration during the dehydration process, an elastic (rubber) member is arranged on the outer peripheral surface of the spring member in the same manner as described above, thereby causing the steel wire of the spring member and the rubber member to frictionally slide, Vibration is damped, but because it uses a suspension rod, it has vertical rigidity, and when tilt vibrations are generated at the start of dehydration, vibration is transmitted between the outer box and the water tank. For this reason, there has been a problem that outer box vibration and noise occur.

本発明は前記従来例の不都合を解消するものとして、洗濯・脱水・乾燥の行程中に、外箱と水槽との間の振動伝達を確実に遮断し、外箱振動および騒音発生を低減できる洗濯乾燥機を提供することを目的とする。 In order to eliminate the disadvantages of the conventional example, the present invention reliably interrupts vibration transmission between the outer box and the water tank during the washing, dehydrating and drying processes, and can reduce outer box vibration and noise generation. The purpose is to provide a dryer.

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、その一部をワイヤやロープなどの可撓性索条により構成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 the washing / drying machine in which the motor is disposed below the dewatering tank via a mechanism such as a gear and a clutch, the suspension means is partially configured by a flexible cable such as a wire or a rope. Features.

水槽は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ので、洗濯行程や脱水行程で洗濯物の片寄りによって洗濯兼脱水槽や水槽が振動しても、外箱と水槽との間での振動伝達が遮断されるから、外箱振動や騒音の小さい洗濯乾燥機が得られるものである。 The water tank is hung from the outer box by a flexible wire such as a wire or rope with less rigidity, so even if the washing / dehydration tank or the water tank vibrates due to the laundry being deviated in the washing or dehydrating process, the outer box Since the transmission of vibration between the water tank and the water tank is cut off, a washing and drying machine with low outer box vibration and noise can be obtained.

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斜視図で、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５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３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 an explanatory view of a side surface showing an embodiment of the washing and drying machine of the present invention, FIG. 2 is an explanatory view of the same plane side, FIG. 3 is a perspective view of a hanging means which is the main part of the same. As already described, the washing / drying machine suspends the water tank 2 from the four corners of the outer box 1 by the suspending means 4 and has a washing / dehydration tank 5 provided with a stirring blade at the bottom although not shown. The motor 3 is disposed in the water tank, and a mechanism such as a gear and a clutch is disposed below the washing and dewatering tank.

本発明は前記吊下げ手段４として、図３に示すように上端に第１の支持片８を取付けたワイヤ６やロープなどの可撓性索条と、その下部に取付けられ、上下を第２の支持片９と第３の支持片１０とで挟着されるバネ部材７とで構成し、バネ部材７の外周面にゴムなどを材質する部材、例えばゴム管などを使用する弾性部材１１を被装した。 In the present invention, as the suspending means 4, as shown in FIG. 3, a flexible wire such as a wire 6 or a rope having a first support piece 8 attached to the upper end thereof, and a lower part thereof are attached to the lower part, and the second is arranged vertically. A spring member 7 sandwiched between the support piece 9 and the third support piece 10, and a member made of rubber or the like on the outer peripheral surface of the spring member 7, for example, an elastic member 11 using a rubber tube or the like. I wore it.

そして、前記第１の支持片８を外箱１の内側に突出させたフランジに係止し、第２の支持片９を水槽２の側部から側方に突出させたフランジに係止する。これにより、吊下げ手段４が外箱１と水槽２との間に懸架され、第２の支持片９が水槽２と接触することになる。 And the said 1st support piece 8 is latched by the flange protruded inside the outer case 1, and the 2nd support piece 9 is latched by the flange protruded from the side part of the water tank 2 to the side. Thereby, the suspending means 4 is suspended between the outer box 1 and the water tank 2, and the second support piece 9 comes into contact with the water tank 2.

この場合、バネ部材７は鉛直方向に対して斜めに向くようにセットする。 In this case, the spring member 7 is set so as to be inclined obliquely with respect to the vertical direction.

また、第２の支持片の水槽２との接触部を、水槽２の上下方向の重心位置よりも下方に配置した。 Moreover, the contact part with the water tank 2 of the 2nd support piece was arrange | positioned below rather than the gravity center position of the up-down direction of the water tank 2. As shown in FIG.

さらに、吊下げ手段４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ワイヤ６を使用する吊下げ手段４を配置する必要はなく、少なくとも対角上または前後に配置すればよく、ワイヤ６以外の吊下げ手段４については従来の吊り棒を使用すれば低コストとなる。なお、吊ワイヤの使用は、吊り棒と同等程度の引張り強度を有し、外箱１内のスペース有効利用が図れる。 Furthermore, the suspending means 4 is arranged at the four corners in the outer box 1, but it is not necessary to arrange the suspending means 4 using the wire 6 according to the configuration of the present invention at all the four corners, at least diagonally or What is necessary is just to arrange | position forward and backward, and about the suspending means 4 other than the wire 6, if it uses a conventional hanging rod, it will become low-cost. Note that the use of the hanging wire has a tensile strength equivalent to that of the hanging rod, and the space in the outer box 1 can be effectively used.

次に動作について説明する。洗濯行程が始ったとき、洗濯物である衣類が洗濯兼脱水槽５内で片寄っているとアンバランスによって、洗濯兼脱水槽５および水槽２に大きな振動が発生する。 Next, the operation will be described. When the washing process starts, if the clothes that are the laundry are offset in the washing / dehydrating tub 5, large vibrations are generated in the washing / dehydrating tub 5 and the water tub 2 due to imbalance.

このとき、弾性部材１１がバネ部材７の外周に配置されているから、バネ部材７の鋼線と弾性部材１１のゴムとが摩擦摺動して振動が減衰される。さらに、吊リ部材がワイヤであることから、ねじり方向への剛性が小さくなり、攪拌翼回転時の反力などで水槽２が回転方向に振動する際に、外箱１と水槽２との間で振動の伝達が遮断され、外箱１の振動および騒音発生が低減する。 At this time, since the elastic member 11 is disposed on the outer periphery of the spring member 7, the steel wire of the spring member 7 and the rubber of the elastic member 11 are frictionally slid to attenuate the vibration. Further, since the suspension member is a wire, the rigidity in the torsional direction is reduced, and when the water tank 2 vibrates in the rotation direction due to a reaction force when the stirring blade rotates, the space between the outer box 1 and the water tank 2 is reduced. Therefore, the transmission of vibration is cut off, and the vibration and noise generation of the outer box 1 are reduced.

また、脱水行程でもアンバランスによって洗濯兼脱水槽５および水槽２に大きな振動が発生することがあるが、この場合も洗濯行程の場合と同様にして外箱１の振動および騒音発生が低減する。 Further, large vibrations may occur in the washing / dehydrating tub 5 and the water tub 2 due to imbalance in the dehydration process, and in this case, the vibration and noise generation of the outer case 1 are reduced in the same manner as in the washing process.

この場合、水槽２と第２の支持片９との接触位置を水槽２の上下方向の重心位置よりも下に位置させたから、例えばワイヤ６を巻き上げて水槽２を傾斜させたときに第２の支持片９が外方に飛出し外箱１の内側に接触することを防止できる。 In this case, since the contact position between the water tank 2 and the second support piece 9 is positioned below the center of gravity of the water tank 2 in the vertical direction, for example, when the water tank 2 is wound up to tilt the water tank 2 It is possible to prevent the support piece 9 from protruding outward and coming into contact with the inside of the outer box 1.

また、バネ部材７は斜めにセットしたから、横振動と傾振動との両方に対して有効に減衰できる。 Further, since the spring member 7 is set obliquely, it can be effectively damped against both lateral vibration and tilt vibration.

なお、吊下げ手段４の構成は、前記のようなワイヤ６で形成する他に、図４〜図６に示すようにワイヤ６と従来使用している吊り棒１２との組合せとすることもできる。 The structure of the suspending means 4 can be a combination of the wire 6 and a conventionally used suspension rod 12 as shown in FIGS. 4 to 6 in addition to the wire 6 as described above. .

この場合、図示のように上部をワイヤ６とし、下部を吊り棒１２とする。そして、両者の結合手段としては、図４のように接続金具１３を使用してワイヤ６の下部をボルト１５で接続金具１３に挟み込んで結合し、吊り棒１２の上部をねじ部１４に形成し、このねじ部１４を接続金具１３に形成したねじ孔に螺合する。 In this case, the upper part is a wire 6 and the lower part is a hanging rod 12 as shown in the figure. Then, as a connecting means between them, as shown in FIG. 4, the lower part of the wire 6 is sandwiched between the connecting metal parts 13 with bolts 15 using the connecting metal parts 13 and the upper part of the suspension rod 12 is formed on the screw part 14. The screw portion 14 is screwed into a screw hole formed in the connection fitting 13.

または、図５に示すように接続金具１３の吊り棒１２との結合部について、係止孔１６を形成するとともに、吊り棒１２の上端をフック部１２ａに形成し、この係止孔１６にフック部１２ａを掛止することで、接続金具１３を介して吊り棒１２とワイヤ６とを結合することもできる。 Alternatively, as shown in FIG. 5, a locking hole 16 is formed in the connection portion of the connection fitting 13 with the suspension rod 12, and the upper end of the suspension rod 12 is formed in the hook portion 12 a, and the hook is inserted into the engagement hole 16. The suspension rod 12 and the wire 6 can be coupled via the connection fitting 13 by hooking the portion 12a.

さらに、図６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１２のフック部１２ａを直接絡み合わせて接続することもできる。 Furthermore, as shown in FIG. 6, it is also possible to form the lower portion of the wire 6 in the hook portion 6a without using a connection fitting, and to connect the hook portion 6a and the hook portion 12a of the suspension rod 12 by directly tangling them.
