이와 같은 본 발명은 하우징(10), 외상(80)의 모서리 상단에 부착되는 현가 지지부재(20), 상기한 하우징(10) 및 현가 지지부재(20) 사이에 연결되는 지지봉(30), 상기한 현가 지지부재(20)의 측면과 밀착하는 마찰부재(33,34)를 구비한 댐퍼(40) 및 저수조(70)의 외벽과 댐퍼(40) 사이에 연결되는 링크(50)로 이루어진다.The present invention as described above, the housing 10, the suspension support member 20 attached to the upper edge of the outer shell 80, the support rod 30 is connected between the housing 10 and the suspension support member 20, the A damper 40 having friction members 33 and 34 in close contact with the side surface of the suspension supporting member 20 and a link 50 connected between the damper 40 and the outer wall of the reservoir 70.

상기한 하우징(10)은 저수조(70)로부터 수평으로 돌출된 연결부재(61)의 하부에 위치하며, 내부에는 압축 코일스프링(1)이 결합되며 상부의 관통공으로는 지지부재(20)의 상부로부터 힌지연결되는 지지봉(30)의 선단이 삽입됨으로써 압축 코일스프링(1)의 탄성에 의해 상기한 지지봉(30)의 선단을 탄성지지한다.The housing 10 is located below the connecting member 61 protruding horizontally from the reservoir 70, the compression coil spring (1) is coupled to the inside and the upper through hole in the upper portion of the support member (20) The front end of the supporting rod 30 is elastically supported by the elasticity of the compression coil spring 1 by inserting the front end of the supporting rod 30 which is hinged.

계속해서 외상(80)의 모서리 상부로부터 수직으로 부착되어 힌지연결된 지지봉(30) 일측을 지지하는 한편, 댐퍼(40)의 결합공간을 제공하는 현가 지지부재(20)는 상부에 관통공(11)이 수평으로 형성되며, 상기한 관통공(11)의 내측으로는 댐퍼(40)의 회전축(31)이 삽입된다.Subsequently, the suspension supporting member 20, which is vertically attached from the upper edge of the outer box 80 and supports one side of the hinged support rod 30, provides a coupling space of the damper 40, and has a through hole 11 thereon. It is formed horizontally, the rotary shaft 31 of the damper 40 is inserted into the through hole 11 is inserted.

상기한 댐퍼(40)는 저수조(70)의 수평방향으로 충격이나 진동에 의한 가압력이 작용할 경우 현가 지지부재(20)와의 마찰에 따른 댐핑력에 의해 충격을 흡수하는 것으로, 현가 지지부재(20)의 관통공(11)을 통해 삽입되는 회전축(31)의 양측으로 로드(31A,31B)가 각각 평행하게 연결되며, 상기한 로드(31A,31B)의 선단으로는 현가 지지부재(20)의 측면과 밀착하는 블럭형상의 마찰부재(33,34)가 각각 부착된다.The damper 40 is to absorb the shock by the damping force caused by friction with the suspension support member 20 when the pressing force by the impact or vibration in the horizontal direction of the reservoir 70, suspension support member 20 The rods 31A and 31B are connected in parallel to both sides of the rotation shaft 31 inserted through the through holes 11, and the side surfaces of the suspension supporting member 20 are connected to the ends of the rods 31A and 31B. And block-shaped friction members 33 and 34 are in close contact with each other.

한편, 상기한 마찰부재(33,34)로는 고무재나 실리콘과 같이 적절한 탄성을 갖는 동시에 현가 지지부재(20)와의 접촉면으로 마찰력을 갖는 소재를 사용하며, 판스프링(32)을 결합시킴에 따라 상기한 판스프링(32)의 탄성에 의해 현가 지지부재(20)와 강한 접촉압력을 갖는 상태로 밀착되도록 한다.On the other hand, the friction members 33 and 34 are made of a material having a proper elasticity, such as rubber or silicone, and having a friction force to the contact surface with the suspension support member 20, and the plate spring 32 is coupled to the The elasticity of the leaf spring 32 is in close contact with the suspension supporting member 20 in a state of having a strong contact pressure.

계속해서 상기한 댐퍼(40)를 구성하는 로드(31A,31B)의 일측으로는 선단이 저수조(70)의 외벽 일측과 힌지연결된 링크(50)가 회전가능하게 연결된다.Subsequently, one end of the rods 31A and 31B constituting the damper 40 is rotatably connected to a link 50 whose tip is hinged to the outer wall of the reservoir 70.

이때, 상기한 링크(50)는 지지봉(30)과의 접촉면에 상기 지지봉(30)의 외경보다 큰 내경의 확장부(41)를 형성함으로써 지지봉(30)의 접촉에 따른 간섭을 배제한다.In this case, the link 50 excludes the interference due to the contact of the support rod 30 by forming an extension 41 having an inner diameter larger than the outer diameter of the support rod 30 on the contact surface with the support rod 30.

이와 같은 본 발명에 의한 세탁기용 현가장치(60)는 저수조(70)의 수직방향으로 충격에 따른 가압력이 작용할 경우에는 하우징(10)에 내장된 압축 코일스프링(1)의 탄성에 의해 충격이 흡수되도록 하며, 저수조(70)의 수평방향으로 충격에 따른 가압력이 작용할 경우에는 댐퍼(40)의 자체 탄성 및 마찰부재(33,34)와 현가 지지부재(20)간의 마찰과정에서 가압력을 소멸시킨다.In the washing machine suspension device 60 according to the present invention, the shock is absorbed by the elasticity of the compression coil spring 1 built in the housing 10 when the pressing force according to the impact in the vertical direction of the water storage tank 70 is applied. When the pressing force according to the impact in the horizontal direction of the reservoir 70 acts, the pressing force is eliminated during the friction process between the self-elasticity of the damper 40 and the friction members 33 and 34 and the suspension support member 20.

상기한 구성으로 이루어진 본 발명의 작용 및 효과를 도 4를 참조하여 이하에서 설명한다.An operation and effects of the present invention having the above configuration will be described below with reference to FIG. 4.

본 발명에 의한 세탁기용 현가장치(60)는 세탁기의 외부에 결합된 외상(80)과 저수조(70) 사이에 개재되어 상기한 저수조(70)를 지지함으로써 세탁조의 회전에 따른 충격과 진동을 흡수한다.Suspension device for washing machine 60 according to the present invention is interposed between the outer casing 80 and the reservoir 70 coupled to the outside of the washing machine to support the reservoir 70 to absorb the shock and vibration caused by the rotation of the washing tank. do.

상기한 바와 같은 본 발명은 저수조(70)에 부착된 연결부재(61)의 하부에 압축 코일스프링(1)이 내장된 하우징(10)을 위치시키고, 외상(80)의 모서리 상부에 부착된 현가 지지부재(20) 및 하우징(10) 사이에는 지지봉(30)을 결합시킨다.As described above, the present invention locates the housing 10 in which the compression coil spring 1 is built in the lower portion of the connecting member 61 attached to the water tank 70, and the suspension attached to the upper edge of the outer box 80. The support rod 30 is coupled between the support member 20 and the housing 10.

계속해서 현가 지지부재(20)의 양측으로는 댐퍼(40)를 구성하는 마찰부재(33,34)를 각각 밀착시키며, 회전축(31)의 로드(31A,31B)와 저수조(70)의외벽 사이에는 링크(50)를 연결시킨다.Subsequently, friction members 33 and 34 constituting the damper 40 are brought into close contact with both sides of the suspension supporting member 20, respectively, between the rods 31A and 31B of the rotating shaft 31 and the outer wall of the reservoir 70. The link 50 is connected.

이때 상기한 바와 같이 외상(80) 및 저수조(70) 사이에 결합되는 본 발명은 외상(80)의 각 모서리 내측으로부터 저수조(70) 사이에 각각 설치함으로써 세탁기의 내부로부터 4조를 각각 설치한다.At this time, the present invention coupled between the trauma 80 and the reservoir 70 as described above is installed between the reservoir 70 from each inside of each corner of the trauma 80 to install four tanks from the inside of the washing machine, respectively.

상기한 바와 같이 결합된 본 발명은 세탁과정에서 저수조(70)의 수직방향으로 가압력이 작용할 경우에는 통상적인 구조의 세탁기용 현가장치와 같이 저수조(70)의 측면 하부에 결합된 하우징(10)의 압축 코일스프링(1)이 압축되는 과정에서 발생하는 완충력에 의해 충격을 흡수한다.The present invention coupled as described above of the housing 10 is coupled to the lower side of the reservoir 70, such as a suspension for a washing machine of the conventional structure when the pressing force acts in the vertical direction of the reservoir 70 in the washing process. The compression coil spring 1 absorbs the shock by the buffer force generated during the compression process.

즉, 예로써 도 4a와 같이 저수조(70)가 하부 방향으로 하강하면, 일정한 길이를 갖는 지지봉(30)의 특성에 따라 하우징(10)에 내장된 압축 코일스프링(1)이 압축되어 충격을 흡수하며, 저수조(70)의 수직방향으로 작용하는 가압력이 제거되면 압축 코일스프링(1)의 탄성에 의해 저수조(70)가 초기의 위치로 복귀한다.That is, for example, when the reservoir 70 is lowered as shown in FIG. 4A, the compression coil spring 1 embedded in the housing 10 is compressed to absorb shocks according to the characteristics of the support rod 30 having a predetermined length. When the pressing force acting in the vertical direction of the reservoir 70 is removed, the reservoir 70 is returned to the initial position by the elasticity of the compression coil spring 1.

계속해서 펄세이터의 회전방향의 전환시나 정지시와 같이 저수조(70)로부터 수평방향으로 가압력이 작용할 경우에는 도 4b와 같이 링크(50)가 가압력의 작용방향과 동일한 방향으로 이동하며, 이에 따라 상기한 링크(50)와 연결된 로드(31A,31B)가 회전하여 마찰부재(33,34)를 화살표 방향으로 이동시킨다.Subsequently, when the pressing force acts in the horizontal direction from the water tank 70 such as when the rotation direction of the pulsator is switched or when stopped, the link 50 moves in the same direction as the acting direction of the pressing force as shown in FIG. 4B. The rods 31A and 31B connected to one link 50 rotate to move the friction members 33 and 34 in the direction of the arrow.

이와 같은 과정에서 상기한 마찰부재(33,34)는 고무재로 이루어짐에 따라 고무재가 갖는 고유의 감쇄력에 의해 측면 방향으로 작용하는 가압력의 일부를 흡수하는 동시에 판스프링(32)의 탄성에 의해 현가 지지부재(20)의 양측과 각각 밀착됨으로써 상기한 현가 지지부재(20)와의 마찰되는 과정에서 수평방향으로 작용하는가압력을 흡수 소멸시킨다.In this process, as the friction members 33 and 34 are made of rubber material, the friction members 33 and 34 absorb the portion of the pressing force acting in the lateral direction by the inherent damping force of the rubber material, and at the same time, they are suspended by the elasticity of the leaf spring 32. By being in close contact with both sides of the support member 20, the pressure applied in the horizontal direction is absorbed and extinguished in the process of friction with the suspension support member 20.

한편, 상기한 과정에서 수평방향으로 작용하는 가압력이 제거되면 중력에 의해 저수조(70)가 초기의 상태로 복귀하는 한편, 전술한 과정의 반복에 따라 수평방향으로 작용하는 진동이나 충격을 흡수한다.On the other hand, when the pressing force acting in the horizontal direction is removed in the above process, the reservoir 70 returns to the initial state by gravity, and absorbs the vibration or shock acting in the horizontal direction according to the repetition of the above-described process.

이상에서 설명한 바와 같이 본 발명은, 수직방향으로 진동이나 충격이 작용할 경우에는 하우징(10)에 내장된 압축 코일스프링(1)의 탄성에 의해 수직방향의 진동 및 충격을 흡수시키며, 수평방향으로 작용하는 진동이나 충격이 작용할 경우에는 현가 지지부재(20) 및 댐퍼(40) 사이에 작용하는 마찰력에 의해 진동이나 충격이 흡수된다.As described above, the present invention absorbs vibration and shock in the vertical direction by elasticity of the compression coil spring 1 embedded in the housing 10 when vibration or shock is applied in the vertical direction, and acts in the horizontal direction. When the vibration or impact acts, the vibration or shock is absorbed by the frictional force acting between the suspension support member 20 and the damper 40.

따라서 본 발명은 펄세이터의 회전방향의 전환시나 정지시와 같이 저수조(70)로부터 수평방향으로 가압력이 작용할 경우에도 진동이나 충격의 발생이 억제되므로 세탁 및 탈수과정에서 발생하는 진동이나 충격과 소음 등을 효과적으로 감소시킬 수 있으며, 이와 함께 모터를 포함한 구동장치의 수명이 저하되는 것을 방지하는 등의 많은 효과가 있다.Therefore, in the present invention, even when the pressing force acts in the horizontal direction from the water tank 70 such as when the rotational direction of the pulsator is switched or when stopped, vibration or shock is suppressed, and thus vibration, shock and noise generated during washing and dehydration. It can effectively reduce the, and with this, there are many effects such as preventing the life of the drive device including the motor is reduced.

이상에서는 본 발명을 특정의 바람직한 실시예에 대하여 도시하고 설명하였으나 본 발명은 상기한 실시예에 한정되지 아니하며, 특허청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형이 가능할 것이다.While the invention has been shown and described with respect to certain preferred embodiments, the invention is not limited to the embodiments described above, it is common in the art to which the invention pertains without departing from the spirit of the invention as claimed in the claims. Anyone with knowledge will be able to make various variations.
