Description

本開示は、スプリングダンパー、蓋板取付構造および洗濯機に関する。   The present disclosure relates to a spring damper, a cover plate mounting structure, and a washing machine.

例えば、洗濯機の蓋板の取付構造または便蓋の取付構造における回転機構において、通常、ダンパーを使用して蓋板をある方向にゆっくりと回動させる。洗濯機における上蓋を例とし、上蓋は、通常、急速に開かれた後にオイルダンパーによってゆっくりと閉じることができるように、オイルダンパーに連結される。このようにして、上蓋の閉じる際に洗濯機の本体を破損することを防止することができる。しかし、オイルダンパーにおけるオイルの存在は、構造の複雑さ、メンテナンスの不便性、およびメンテナンスコストを増加させる。   For example, in a rotation mechanism in a lid plate attachment structure or a toilet lid attachment structure of a washing machine, a lid plate is usually slowly rotated in a certain direction using a damper. Taking an upper lid in a washing machine as an example, the upper lid is usually connected to an oil damper so that it can be opened slowly and then slowly closed by the oil damper. In this way, it is possible to prevent the main body of the washing machine from being damaged when the upper lid is closed. However, the presence of oil in the oil damper increases structural complexity, maintenance inconvenience, and maintenance costs.

本開示によるスプリングダンパーの構造模式図である。It is a structure schematic diagram of the spring damper by this indication.

以下、図面を参照しながら、本発明の具体的な実施形態について詳細に説明する。本開示の１つの態様によれば、スプリングダンパーを提供する。図１に示すように、スプリングダンパーは、ハウジング１と、ハウジング１に回動可能に取り付けられる回転軸２とを備える。回転軸２の一端はハウジング１の内壁に連結される。回転軸２のハウジング１内に位置する部位にスプリング３が嵌設される。好ましくは、スプリング３は回転軸２の軸方向に沿って回転軸２に嵌設される。スプリング３の第１端はハウジング１に固定される。回転軸２がハウジング１に対して回転すると、スプリング３は回転軸２を緊締したり解放する。すなわち、前記スプリング（３）は、回転軸（２）の回動に伴って前記回転軸（２）を緊締したり解放するように構成される。   Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. According to one aspect of the present disclosure, a spring damper is provided. As shown in FIG. 1, the spring damper includes a housing 1 and a rotating shaft 2 that is rotatably attached to the housing 1. One end of the rotating shaft 2 is connected to the inner wall of the housing 1. A spring 3 is fitted in a portion of the rotating shaft 2 located in the housing 1. Preferably, the spring 3 is fitted on the rotary shaft 2 along the axial direction of the rotary shaft 2. A first end of the spring 3 is fixed to the housing 1. When the rotating shaft 2 rotates with respect to the housing 1, the spring 3 tightens or releases the rotating shaft 2. That is, the spring (3) is configured to tighten or release the rotating shaft (2) as the rotating shaft (2) rotates.

上述したように、本開示に係るスプリングダンパーは、ハウジング１と、ハウジング１に回動可能に取り付けられる回転軸２とを備え、回転軸２のハウジング１内に位置する部位にスプリング３が嵌設され、スプリング３の第１端がハウジング１に固定され、それにより、回転軸２とハウジング１とが互いに相対回転すると、スプリング３は回転軸２を緊締したり解放することができるため、スプリング３が回転軸２を緊締することにより、回転軸２とハウジング１との間の動きに抵抗を生じさせ、ダンパー効果を得ることができる。スプリング３をダンパー部材として使用することで、該スプリングダンパーは、構造が簡単で、メンテナンスしやすく、メンテナンスコストが低く、且つ、ダンパーオイルが不要となる。   As described above, the spring damper according to the present disclosure includes the housing 1 and the rotary shaft 2 that is rotatably attached to the housing 1, and the spring 3 is fitted in a portion of the rotary shaft 2 located in the housing 1. The first end of the spring 3 is fixed to the housing 1, so that when the rotary shaft 2 and the housing 1 rotate relative to each other, the spring 3 can tighten or release the rotary shaft 2. By tightening the rotating shaft 2, resistance is generated in the movement between the rotating shaft 2 and the housing 1, and a damper effect can be obtained. By using the spring 3 as a damper member, the spring damper has a simple structure, is easy to maintain, has a low maintenance cost, and does not require damper oil.

１つの実施例において、スプリング３の第１端は、回転軸２の径方向に沿ってハウジング（１）の内壁へ延在するスプリングアーム３１として形成することができ、スプリングアーム３１とハウジング１の内壁面とは互いに固定される。好ましくは、ハウジング１の内壁面に位置決め溝が設けられてもよく、スプリングアーム３１が位置決め溝に挿着固定されてもよい。スプリングアーム３１は、他の適当な連結方式によりハウジング１に固定されてもよい。   In one embodiment, the first end of the spring 3 can be formed as a spring arm 31 that extends to the inner wall of the housing (1) along the radial direction of the rotating shaft 2. The inner wall surface is fixed to each other. Preferably, a positioning groove may be provided on the inner wall surface of the housing 1, and the spring arm 31 may be inserted and fixed in the positioning groove. The spring arm 31 may be fixed to the housing 1 by other suitable connection methods.

好ましくは、回転軸２は、ハウジング１の内部に位置する大径柱部２１と、大径柱部２１に連結されかつハウジング１を貫通する回転レバー部２２とを備える。好ましくは、前記ハウジング１に開口が設けられ、前記回転レバー部２２は前記ハウジング１の開口を介して延び出す。スプリング３は回転軸２の大径柱部２１に設けられる。回転レバー部２２の最大断面積は、大径柱部２１の最小断面積よりも小さい。   Preferably, the rotary shaft 2 includes a large-diameter column portion 21 located inside the housing 1 and a rotation lever portion 22 that is connected to the large-diameter column portion 21 and penetrates the housing 1. Preferably, the housing 1 is provided with an opening, and the rotating lever portion 22 extends through the opening of the housing 1. The spring 3 is provided on the large-diameter column portion 21 of the rotating shaft 2. The maximum cross-sectional area of the rotating lever portion 22 is smaller than the minimum cross-sectional area of the large-diameter column portion 21.

本開示の別の態様によれば、蓋板取付構造を更に提供する。蓋板取付構造は、機体、蓋板、および上記スプリングダンパーを備える。回転軸２は機体に取り付けられ、ハウジング１は蓋板に連結される。スプリング３は、蓋板が機体に対して開くと、回転軸２を徐々に解放させ、蓋板が機体に対して閉じると、回転軸２を徐々に緊締するように構成されてもよい。スプリング３は、回転軸２に時計回りに巻回され、または反時計回りに巻回されてもよい。スプリング３が反時計回りに大径柱部２１の外周面に巻回されて延在する設置方式により、蓋板が機体に対して開くと、スプリング３は回転軸２を徐々に解放させる。スプリング３が時計回りに大径柱部２１の外周面に巻回されて延在する設置方式により、蓋板が機体に対して開くと、スプリング３は回転軸２を徐々に緊締する。該蓋板取付構造は、洗濯機の蓋板取付構造または便座の蓋板取付構造とすることができ、蓋板５の閉じ速度が速すぎることで他の部材を破損することを防止できる。しかし、本開示はこれに限定されず、一方、スプリング３は、必ずしも蓋板が開くと回転軸２を徐々に解放させ、蓋板が閉じると回転軸２を徐々に緊締するように構成されるのではなく、ユーザーは蓋板を迅速に閉じ、蓋板をゆっくりと開く必要がある場合、スプリング３を、蓋板が開くと回転軸２を徐々に緊締し、蓋板が閉じると回転軸２を徐々に解放させるように構成してもよい。他方、該蓋板取付構造は、洗濯機の蓋板取付構造または便座の蓋板取付構造に限定されない。   According to another aspect of the present disclosure, a lid plate mounting structure is further provided. The cover plate mounting structure includes a body, a cover plate, and the spring damper. The rotating shaft 2 is attached to the airframe, and the housing 1 is connected to the lid plate.
