Description
【０００１】[0001]
本考案は、洗濯機の脚装置に関する。 The present invention relates to a leg device of a washing machine.
【０００２】[0002]
従来例として、洗濯機本体の底部に設けられた固定脚の床面との間に円筒形の 弾性脚を介在し、この弾性脚の床面との接地面に、凹部または凸部を設けた洗濯 機の脚装置が、特開平２−７２２９８号公報（Ｆ１６Ｍ １１／２２）に示され ている。 As a conventional example, a cylindrical elastic leg is interposed between the fixed leg provided on the bottom of the washing machine body and the floor surface, and a concave portion or a convex portion is provided on the ground contact surface with the floor surface of the elastic leg. A leg device of a washing machine is disclosed in Japanese Patent Laid-Open No. 2-72298 (F16M 11/22).
【０００３】 脱水初期に、脱水槽を駆動するモータの回転数が１００〜２００ｒｐｍになる と外槽は共振して大きく振動し、それによって洗濯機本体は大きく振動する。そ の後、駆動モータは、８００〜９００ｒｐｍに達すると、高速同期回転する（以 下この期間を脱水安定期という）が、このとき、外槽は細かく振動し、洗濯機本 体も細かく振動する。When the number of rotations of the motor for driving the dehydration tub reaches 100 to 200 rpm in the initial stage of dehydration, the outer tub resonates and vibrates greatly, which causes the main body of the washing machine to vibrate greatly. After that, when the drive motor reaches 800 to 900 rpm, it rotates at high speed synchronously (hereinafter, this period is called the dehydration stable period), but at this time, the outer tub vibrates finely and the washing machine body also vibrates finely. .
【０００４】 上記従来例は、弾性脚の床面との接地面に、凹部または凸部を設けることによ り、脱水初期には、床面との接地面積を大きくし、強固な支持状態とすることで 、振幅を抑え、脱水安定期には、素早く弾性脚を上下に伸縮させて細かな振動を 吸収することで、洗濯機本体の振動を低減するものである。In the above-mentioned conventional example, by providing a concave portion or a convex portion on the ground contact surface of the elastic leg with the floor surface, the ground contact area with the floor surface is increased at the initial stage of dehydration, and a strong support state is obtained. By doing so, the amplitude is suppressed, and during the dehydration stable period, the elastic legs are quickly expanded and contracted up and down to absorb small vibrations, thereby reducing the vibration of the washing machine body.
【０００５】[0005]
しかし従来例にあっては、弾性脚の構造が非常に複雑で、成形しにくいという 問題があった。 However, in the conventional example, there is a problem that the structure of the elastic leg is very complicated and it is difficult to form.
【０００６】 本考案は、斯かる問題点を解消するものである。The present invention solves such a problem.
【０００７】[0007]
【課題を解決するための手段】 本考案の洗濯機の脚装置は、洗濯機本体の底部に設けられ、下側に開口する凹 所を有する固定脚と、この固定脚の凹所内に止着され、前記固定脚を介して洗濯 機本体を床面に弾性支持する球形の弾性脚とを備えている。Means for Solving the Problems A leg device for a washing machine according to the present invention comprises a fixed leg provided at a bottom portion of a main body of a washing machine and having a recess opening to the lower side, and a fixing device fixed in the recess of the fixed leg. And a spherical elastic leg that elastically supports the main body of the washing machine on the floor through the fixed leg.
【０００８】[0008]
弾性脚が球形であるので、上方からの荷動に対し、圧縮されやすく、脱水初期 には、床面との接地面積が大きくなって、大きな振動を低減できる。 Since the elastic legs are spherical, they are easily compressed against load motion from above, and the ground contact area with the floor surface becomes large in the early stages of dehydration, and large vibrations can be reduced.
【０００９】[0009]
本考案の実施例を各図面に基づいて説明する。 An embodiment of the present invention will be described with reference to the drawings.
【００１０】 図３において、１は機枠、２はこの機枠１内に４本の吊り棒３により吊り下げ 支持された外槽、４は各吊り棒３と外槽２下部側壁との間に介挿された防振装置 、５は外槽２内に回転自在に支承された洗濯兼脱水槽で、図示しないが周囲に多 数の脱水孔を有している。６はこの洗濯兼脱水槽５の底部に回転自在に配設され た回転翼、７は洗濯兼脱水槽５及び回転翼６に動力伝達機構８を介して連結され た駆動モ−タで、洗濯時には回転翼６のみを回転させ、脱水時には洗濯兼脱水槽 ５、回転翼６共に高速で一方向回転させる。In FIG. 3, 1 is a machine frame, 2 is an outer tank suspended and supported by four suspension bars 3 in the machine frame 1, 4 is a space between each suspension bar 3 and a lower side wall of the outer tank 2. The anti-vibration device 5 inserted in the outer tub 2 is a washing / dehydrating tub rotatably supported in the outer tub 2 and has a large number of dewatering holes in the periphery although not shown. 6 is a rotary blade rotatably arranged at the bottom of the washing / dehydrating tub 5, and 7 is a drive motor connected to the washing / dehydrating tub 5 and the rotary wing 6 via a power transmission mechanism 8. At times, only the rotary blades 6 are rotated, and at the time of dehydration, both the washing / dehydrating tank 5 and the rotary blades 6 are rotated in one direction at high speed.
【００１１】 図１及び図２において、９は洗濯機本体の底部に設けられた脚台である。１０ はこの脚台９のコーナー部近傍４ケ所に設けられ、下側に開口する円筒形の固定 脚で、開口部では、内側に向かって３ケ所から突起片１１が張り出している。従 って、開口部はその分固定脚中央部の内径よりも小さくなっている。１２は固定 脚１０に遊嵌された球形の弾性脚で、その径は固定脚中央部の内径より小さく開 口部よりも大きい。この弾性脚１２は、横の径が小さくなるよう縦長に圧縮され て開口部から嵌入され、一旦嵌入されると、その径が開口部より大きいので、洗 濯機本体が持ち上げられても、固定脚１０から外れ落ちることはない。In FIG. 1 and FIG. 2, 9 is a foot stand provided at the bottom of the main body of the washing machine. Numeral 10 is a cylindrical fixed leg which is provided at four places near the corners of the leg base 9 and opens downward. At the opening, projecting pieces 11 project inward from three places. Therefore, the opening is smaller than the inner diameter of the central portion of the fixed leg by that amount. Numeral 12 is a spherical elastic leg loosely fitted in the fixed leg 10, and its diameter is smaller than the inner diameter of the central portion of the fixed leg and larger than the opening. The elastic leg 12 is compressed vertically so as to have a smaller horizontal diameter, is fitted into the opening, and once fitted, the diameter is larger than the opening. Therefore, even if the washing machine body is lifted, the fixed leg is fixed. It never falls off 10.
【００１２】 また、ここでは、弾性脚の材質は、イソプレン・イソブチルゴムまたはポリノ ルボルネン系ゴム等の軟質ゴムである。Further, here, the material of the elastic leg is a soft rubber such as isoprene-isobutyl rubber or polynorbornene rubber.
【００１３】 脱水初期には、洗濯兼脱水槽５内の洗濯物が水分を多く含んでいるので、洗濯 機本体は重くなり、固定脚１０を介し本体を支えている弾性脚１２には大きな加 重が加わる。弾性脚１２は、固定脚１０に遊嵌されているので、図４のように上 部、下部とも大きく圧縮され、床面との接地面積は大きくなる。このとき、外槽 ２が共振して大きく揺れても、弾性脚１２は、接地面積は大きく、強固な支持状 態になっているので洗濯機本体は大きく揺れない。At the initial stage of dehydration, since the laundry in the washing / dehydrating tub 5 contains a large amount of water, the main body of the washing machine becomes heavy, and the elastic legs 12 supporting the main body via the fixed legs 10 are subjected to a large load. Adds weight. Since the elastic leg 12 is loosely fitted to the fixed leg 10, both the upper part and the lower part are largely compressed as shown in FIG. 4, and the ground contact area with the floor surface becomes large. At this time, even if the outer tub 2 resonates and shakes greatly, the elastic leg 12 has a large ground contact area and is in a strong supporting state, so that the washing machine body does not shake greatly.
【００１４】 一方、脱水安定期には洗濯物の水分が排出されるので洗濯機本体は軽くなって くる。本体が軽くなると、弾性脚１２は、図５のように球に近い形状になる。こ のとき弾性脚１２は、細かな振動に対応させて素早く上下に伸縮し、振動を吸収 する。On the other hand, since the water content of the laundry is discharged during the dehydration stable period, the main body of the washing machine becomes lighter. When the body becomes lighter, the elastic legs 12 have a shape close to a sphere as shown in FIG. At this time, the elastic leg 12 quickly expands and contracts vertically in response to small vibrations and absorbs the vibrations.
【００１５】 以上のように、本実施例の洗濯機の脚装置においては、脱水初期には、脚を強 固にし大きな振動を抑えることができ、かつ、脱水安定期には、細かな振動に対 応させて素早く弾性脚を上下伸縮させ振動を吸収することができる。よって、洗 濯機本体の振動を低減することができる。As described above, in the leg device of the washing machine of this embodiment, the legs can be strengthened to suppress large vibrations in the initial stage of dehydration, and fine vibrations can be generated during the dehydration stable period. In response, the elastic legs can be expanded and contracted vertically to absorb vibration. Therefore, the vibration of the main body of the washing machine can be reduced.
【００１６】 さらに、弾性脚の構造が非常に簡単で、成形しやすく、また、固定脚への止着 も、弾性脚を変形させて開口部より挿入するだけででき、ネジなどで止める必要 がないので、コストがかからず、取り付け作業も簡単に行うことができる。Further, the structure of the elastic leg is very simple, it is easy to mold, and the fixing to the fixed leg can be done only by deforming the elastic leg and inserting it from the opening, and it is necessary to fix it with screws or the like. Since it is not necessary, the cost is low and the installation work can be performed easily.
【００１７】 なお、本脚装置は、完全自動式洗濯乾燥機等、脱水時の振動が特に大きいドラ ム式の洗濯機に対し、さらに大きく効果を発揮する。The leg device is even more effective for a drum type washing machine such as a fully automatic washer / dryer in which vibration during dehydration is particularly large.
【００１８】[0018]
本考案の洗濯機の脚装置の構成によれば、脱水初期及び脱水安定期の洗濯機本 体の振動を、大きく低減することができる。 According to the constitution of the leg device of the washing machine of the present invention, the vibration of the washing machine body in the initial stage of dehydration and the stable period of dehydration can be greatly reduced.
【００１９】 また、弾性脚の構造が簡単なので、成形しやすく、コストも削減できる。Further, since the elastic legs have a simple structure, they can be easily molded and the cost can be reduced.
