본 고안은 세탁기의 방진장치, 보다 상세하게는 세탁 및 탈수과정에서 세탁물의 불균형과 구동원심력에 의하여 탈수조에 가해지는 불규칙한 요동을 방지하여 진동으로 인한 손상을 감소할 수 있게 한 세탁기의 방진장치에 관한 것이다.The present invention relates to a dustproof device of a washing machine, and more particularly, to a dustproof device of a washing machine, which can prevent damage caused by vibration by preventing irregular shaking applied to a dehydration tank due to unbalance of laundry and driving centrifugal force during washing and dewatering. will be.

일반적으로 대부분의 세탁기에는 세탁 및 탈수시 발생되는 진동과 충격을 흡수하는 완충장치를 구비하고 있다.In general, most washing machines include a shock absorber that absorbs vibration and shock generated during washing and dehydration.

이러한 종래의 완충장치는 세탁조(1)와 그 하단에 취부된 구동축(2)을 지지하여주는 탈수조(3)에 브라켓(3')을 일체로 형성하고, 상단이 세탁기 본체(4)의 상측에 취부된 형가봉(5)이 탄발스프링(6)에 의해 이 브라켓(3')에 구속·지지된 구조로 되어 있다(제1도 참조).The conventional shock absorber is integrally formed with a bracket (3 ') in the dehydration tank (3) for supporting the washing tank (1) and the drive shaft (2) attached to the lower end, the upper end of the washing machine body (4) The mold bar 5 attached to the bracket 3 is restrained and supported by the bracket 3 'by the ball spring 6 (see FIG. 1).

따라서, 세탁 및 탈수시 발생되는 요동현상과 중량을 탈수조에 부설된 완충장치에 의해 흡수·지탱하였다.Therefore, the shaking phenomenon and the weight generated during washing and dehydration were absorbed and supported by the shock absorber attached to the dehydration tank.

그러나 상기한 기술은 탈수조의 상하방향으로 가해지는 충격 및 진동은 원활하게 방지할 수 있는 반면, 수류의 거듭된 반전 및 탈수과정에서 발생되는 불규칙한 난동현상, 즉 현가상태로 된 지지체 내에서 회전되는 세탁조의 세탁물이 불균일할 때 질량과 그 회전중심이 다르게 됨으로써 나타나는 불규칙하고 과도한 진동현상을 제대로 흡수할 수 없었다.However, the above technique can smoothly prevent the impact and vibration applied to the up and down direction of the dehydration tank, while the irregular turbulence generated during repeated inversion and dehydration of the water stream, that is, the washing tank rotated in the suspended support body. When the laundry was uneven, the mass and its center of rotation could not be absorbed properly.

이에 따라 현가상태로 지지된 탈수조가 요동되면서 본체의 내주벽에 부딪히게 되어 소음 및 파손이 초래되는 문제점이 있었으며, 상기 난동현상과 충돌현상은 세탁량이 많을 수록 더욱 증가됨으로써 세탁기의 사용수명을 단축케 하는 하나의 요인이 되기도 하였다.Accordingly, the dehydration tank supported in the suspended state is bumped into the inner circumferential wall of the main body, causing noise and damage. The riot phenomenon and the collision phenomenon increase with more washing, thereby shortening the service life of the washing machine. It was also a factor.

본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로서, 본 고안의 목적은 탈수조의 원주방향을 따라 발생되는 불규칙한 요동, 즉 난동현상을 방지하는 세탁기의 방진장치를 제공함에 있다.The present invention has been made in view of the above problems, and an object of the present invention is to provide an anti-vibration device of a washing machine to prevent irregular fluctuations, that is, phenomena caused by the circumferential direction of the dehydration tank.

이러한 본 고안은, 탈수조를 현가상태로 지지하는 완충장치와 더불어 탈수조의 외주면 중앙부위를 지지하도록 기기본체의 내주벽사이에 댐퍼수단을 부설함에 따라, 탈수조의 상하방향 및 측면방향으로 가해지는 요동을 방지하여 충격과 진동으로부터 발생되는 여러 문제점들을 해결할 수 있게 함을 특징으로 한 것이다.This invention, the damping means applied in the vertical direction and the lateral direction of the dehydration tank by providing a damper means between the inner peripheral wall of the main body of the apparatus body to support the central portion of the outer circumferential surface of the dehydration tank together with the buffer for supporting the dehydration tank in suspension. It is characterized in that it is possible to solve the various problems resulting from shock and vibration.

제2도 내지 제4도는 본 고안의 실시예를 나타낸 것으로서, 세탁기 본체(4)와 탈수조(3)의 외주면 사이에 부설되는 댐퍼수단(10)에는 신축작용을 하는 가요성의 주름부재(20)와 커버(21)에 의해 밀봉된 진공실(30)이 구비되고, 이 진공실의 내부에는 완충력을 제공하는 점성액 및 고체입자가 혼합된 혼합물(G)이 충입되어 있으며, 상기 진공실(30)은 세탁기 본체(4)의 내주벽에 부착할 수 있게 브라켓(22)에 고정되어 있다.2 to 4 show an embodiment of the present invention, the flexible wrinkle member 20 that stretches the damper means 10 is provided between the washing machine main body 4 and the outer peripheral surface of the dehydration tank (3) And a vacuum chamber 30 sealed by a cover 21, and the inside of the vacuum chamber is filled with a mixture G in which a viscous liquid and solid particles are mixed to provide a buffering force, and the vacuum chamber 30 is a washing machine. The bracket 22 is fixed to the inner circumferential wall of the main body 4.

그리고, 주름부재(20)의 일면에 돌출되어 있는 가이드부(20')에는 결합부재(40)의 일측단에 형성된 걸림돌기(41)가 끼워붙임 되며, 결합부재(40)의 타측단에 형성된 결합편(42)은 탈수조(3)의 외면에 부설된 보스(3)에 취부되어 있다.Then, the locking projection 41 formed at one end of the coupling member 40 is fitted to the guide portion 20 ′ protruding from one surface of the pleating member 20, and formed at the other end of the coupling member 40. The engaging piece 42 is attached to the boss 3 attached to the outer surface of the dehydration tank 3.

한편, 상기 댐퍼수단(10)은 탈수조(3)의 외측에 방사상으로 위치되게 다수곳에 설치되며, 그 설치위치는 탈수조의 중앙부위가 바람직한 것으로 확인되었다.On the other hand, the damper means 10 is installed in a number of places to be radially located on the outside of the dehydration tank (3), the installation position was confirmed that the central portion of the dehydration tank is preferable.

또한, 댐퍼수단(10)의 완충기능은 진공실(30)에 의해 형성된 공압과 이 진공실에 충입된 점성액에 의한 유압을 이용한 것이나, 스프링 및 그 외의 탄성재를 이용한 것도 가능하다.In addition, the damping means of the damper means 10 may use the pneumatic pressure formed by the vacuum chamber 30 and the hydraulic pressure by the viscous liquid charged to this vacuum chamber, and it is also possible to use the spring and other elastic materials.

따라서, 상기와 같은 본 고안은, 세탁 및 탈수시 탈수조(3)의 수직방향으로 진동이 가해짐과 아울러 구동축(2)을 깃점으로 측면방향으로 불규칙한 진동이 가해지게 되면, 수직방향의 진동은 현가봉(5)과 스프링(6)으로 된 완충장치에 의해 종래와 동일한 작용으로 흡수되고, 측면방향의 진동은 댐퍼수단(10)에 의해 흡수된다.Therefore, the present invention as described above, when the vibration is applied in the vertical direction of the dehydration tank (3) during washing and dehydration, and the irregular vibration is applied to the side of the drive shaft (2) as a flag point, the vibration in the vertical direction is A shock absorber comprising a suspension rod 5 and a spring 6 is absorbed in the same manner as in the prior art, and vibration in the lateral direction is absorbed by the damper means 10.

즉, 탈수조(3)의 사방에 부착된 결합부재(40)에 탈수조로부터 발생된 충격이 가해지면, 이 충격이 가해지는 방향과 대응된 다른쪽 결합부재(40)가 동시에 반사작용을 한다.That is, when an impact generated from the dehydration tank is applied to the coupling member 40 attached to all sides of the dehydration tank 3, the other coupling member 40 corresponding to the direction in which the impact is applied is simultaneously reflected. .

이에 의하여 일측결합부재(40)에 가해지는 힘은 걸림돌기(41)와 가이드부(20')를 통하여 진공실(30)이 수축되도록 주름부재(20)를 수축시키는 반면, 상기와 상응하는 작용을 하는 타측 결합부재(40)는 진공실(30)이 팽창되게 주름부재(20)를 신장하게 된다.As a result, the force applied to the one side coupling member 40 causes the corrugation member 20 to contract so that the vacuum chamber 30 is contracted through the locking protrusion 41 and the guide portion 20 '. The other coupling member 40 extends the wrinkle member 20 so that the vacuum chamber 30 is expanded.

이러한 진공실(30)의 확대 및 수축작용과 주름부재(20)의 신축작용은 진동을 흡수하고 충격을 상쇄시켜 감소하는 작용을 한다.The expansion and contraction of the vacuum chamber 30 and the expansion and contraction of the pleating member 20 absorb the vibration and cancel the shock to reduce the effect.

또한, 완충기능을 수행하는 진공실(30)내에는 액상의 혼합물(G)이 충입되어 있으므로 공기 및 탄성에 의한 경우보다 충격 흡수율이 높으며, 완충작용으로 인하여 변위되는 결합부재(40)의 위치 보상은 주름부재(20)의 신축에 의하여 이루어지므로 탈수조의 진동 및 충격이 현저히 감소하게 된다.In addition, since the liquid mixture (G) is filled in the vacuum chamber 30 that performs the buffer function, the shock absorption is higher than that caused by air and elasticity, and the position compensation of the coupling member 40 displaced due to the buffer action is Since it is made by the expansion and contraction of the pleating member 20, the vibration and impact of the dehydration tank is significantly reduced.

이와 같은 본 고안은, 탈수조에 가해지는 상하방향의 충격은 물론 측면방향으로 가해지는 불규칙한 요동을 현저히 감소시켜 정숙하고 원활한 구동효과를 얻을 수 있으며, 충격 및 진동으로 인하여 발생되는 소음 및 기기의 손상을 방지할 수 있는 장점이 있는 것이다.The present invention, as well as the up and down impact applied to the dehydration tank, as well as the irregular fluctuations applied in the lateral direction can be significantly reduced to obtain a quiet and smooth driving effect, noise and damage caused by the vibration and the device damage There is an advantage that can be prevented.
