Description

세탁기의 현가장치Suspension of washing machine

제1도는 종래 세탁기의 현가장치를 도시한 세탁기의 일부 측단면도1 is a partial side cross-sectional view of a washing machine showing a suspension of a conventional washing machine

제2도는 제1도의 a부 확대 단면도2 is an enlarged cross-sectional view of part a of FIG.

제3도는 본 고안에 따른 현가장치의 요부 단면도3 is a sectional view of main parts of the suspension according to the present invention.

본 고안은 세탁기 가동시 발생하는 진동을 효과적으로 흡수, 완충시켜 주기 위한 세탁기의 현가장치에 관한 것이다.The present invention relates to a suspension of a washing machine for effectively absorbing and buffering the vibration generated during the operation of the washing machine.

일반적으로 세탁기는 급수, 세탁, 헹굼, 배수 및 탈수 행정을 기히 설정된 프로그램에 의해 순차적으로 수행하여 세탁물을 세탁하도록 구성한 것으로, 세탁기의 대략적인 구성을 보면 사각함체의 형상을 갖는 외체(100) 내에 저수조(20)가 있으며, 이 저수조(20)의 내측에는 세탁물이 담겨지는 세탁조(3)가 있다. 세탁조(30)의 내부 저면 상으로는 회전익(50)이 위치하여 구동부(40)의 동력을 받아 회전한다. 세탁수가 담기는 저수조(20)는 외체(100)에 매달린 상태로 조립되는데, 외체(100)에 저수조(20)를 걸쳐서 지지하여 주는 것을 현가장치(10)라 한다.In general, the washing machine is configured to wash the laundry by sequentially performing the water supply, washing, rinsing, draining, and dehydrating strokes sequentially by a set program. Referring to the general configuration of the washing machine, the washing machine in the outer body 100 having the shape of a blind box is shown. There is 20, and there is a washing tank 3 in which laundry is contained inside the water storage tank 20. The rotor blade 50 is positioned on the inner bottom surface of the washing tub 30 and rotates under the power of the driving unit 40. The water tank 20 containing the washing water is assembled in a state suspended from the outer body 100, and supporting the storage tank 20 over the outer body 100 is called a suspension device 10.

종래 현가장치(10)의 구성을 살펴 보면, 하우징(11)의 내부 공간에는 완충 역할을 하는 스프링(12)이 위치하며, 스프링(12)의 하부로는 댐핑편(13)이 있다. 댐핑편(13)의 저면으로부터 삽입되는 걸이봉(14)은 스프링(12)의 중심부를 지나 하우징(11)의 상부로 빠져나온다. 하우징(11)의 상부로 빠져나온 걸이봉(14)은 충분한 길이를 가지면서 외체(100)에 상부에서 외체(100)에 핀(15)로 결합되어 있다. 하우징(11)의 상부에서는 결합편(16)이 저수조(20)에 부착되어 있다. 종래의 현가장치(10)는 저수조(30)와 세탁조(20)에 담기는 세탁물과 세탁수의 하중에 의해 일단 스프링(12)이 압축된다. 세탁과 탈수행정에서는 스프링(12)이 압축과 복원운동을 반복하고, 이와 함께 상하로 왕복운동하는 댐핑편(13)이 하우징(11) 내의 공기를 압축하므로써 발생하는 댐핑효과에 의해 세탁과 탈수에서 발생하는 진동을 흡수하여 세탁기의 흔들림과 소음을 예방하게 된다.Looking at the configuration of the conventional suspension device 10, a spring 12 that acts as a buffer is located in the internal space of the housing 11, the lower portion of the spring 12 is a damping piece (13). The hook rod 14 inserted from the bottom surface of the damping piece 13 passes through the center of the spring 12 to the upper portion of the housing 11. The hook rod 14 which has exited to the upper portion of the housing 11 has a sufficient length and is coupled to the outer body 100 by a pin 15 from the upper side to the outer body 100. In the upper part of the housing 11, the engaging piece 16 is attached to the reservoir 20. In the conventional suspension device 10, the spring 12 is once compressed by the load of the laundry and the wash water contained in the water storage tank 30 and the washing tank 20. In the washing and dehydrating stroke, the spring 12 repeats the compression and restoration movement, and the damping piece 13 which reciprocates up and down together compresses the air in the housing 11, thereby causing the washing and dehydration. Absorb the vibration generated to prevent shaking and noise of the washing machine.

상기와 같은 종래의 현가장치는 세탁기가 대용량화되면서 최대 하중에 맞게 탄성계수가 큰 스프링을 사용하여 왔다. 하지만, 탄성계수가 큰 스프링은 작은 하중이 걸리게 되면 충분한 탄성력를 제공하지 못하는 단점이 있다. 즉, 작은 하중이 걸린 상태에서 세탁과 탈수행정을 수행하는 과정에서 발생하는 진동에 대한 민감한 역반응을 제공하지 못하고 진동을 그대로 세탁기 외체와 주변장치에 곧 바로 전달하여 세탁기의 흔들림과 수명 단축을 야기하는 문제가 있는 것이다.The conventional suspension as described above has been using a spring with a large modulus of elasticity to meet the maximum load while the washing machine becomes larger. However, a spring with a large modulus of elasticity does not provide sufficient elastic force when a small load is applied. That is, it does not provide a sensitive reverse reaction to the vibration generated during the washing and dehydrating stroke under a small load, and transmits the vibration directly to the washing machine's exterior and peripherals, causing the washing machine to shake and shorten its life. There is a problem.

본 고안은 상기와 같은 종래 문제점을 해결하기 위한 것으로, 그 목적은 진동 흡수가 우수한 세탁기의 현가장치를 제공하여 세탁기의 안정성과 수명을 향상시키는데 있다.The present invention is to solve the conventional problems as described above, the object is to provide a suspension of the washing machine excellent in vibration absorption to improve the stability and life of the washing machine.

상기의 목적을 달성하기 위하여, 본 고안은, 하우징과 스프링, 댐핑편, 걸이봉으로 구성되는 세탁기의 현가 장치에 있어서, 탄성계수가 작고 하우징과 비교하여 자유장이 긴 스프링을 약간 압축시킨 상태로 하우징에 삽입하고 압축된 스프링의 복원력을 억제하는 스톱퍼를 하우징의 상부에 체결하는 것을 특징으로 하는 세탁기의 현가 장치를 제공한다.In order to achieve the above object, the present invention is a suspension device of a washing machine composed of a housing, a spring, a damping piece, and a hanger rod, the housing having a small elastic modulus and a spring having a long free length compared to the housing slightly compressed. It provides a suspension device for a washing machine characterized in that the fastener is inserted into the fastener to suppress the restoring force of the compressed spring to the upper portion of the housing.

이하 첨부된 제 3 도에 의거하여 본 고안의 일 실시예를 설명한다.Hereinafter, an embodiment of the present invention will be described with reference to FIG. 3.

하우징(11)에는 스프링(12)을 내장한다. 스프링(12)은 탄성계수가 작으면서 그 자유장이 하우징(11)과 비교하여 다소 긴 것을 사용한다. 하부에서는 댐핑면(13)이 스프링(12)을 받치는 상태가 되도록 삽입한다. 다음, 걸이봉(14)을 댐핑면(13)의 저면으로부터 삽입하여 스프링(12)의 중심부를 지나 하우징(11)의 상부로 관통 되도록 결합한다. 걸이봉(14)를 잡아 당겨 스프링(12)이 압축된 상태로 하우징(11) 내에 완전히 들어가도록 하면서 걸이봉(14)의 상부에 스톱퍼(1)를 고정시킨다. 이 처럼되면 스프링(12)은 계속적으로 압축된 상태를 유지하게 된다. 이후, 걸이봉(14)을 외체(100)에 핀(15)로 결합한다.The housing 11 incorporates a spring 12. The spring 12 has a small modulus of elasticity and uses a slightly longer free field compared to the housing 11. In the lower portion, the damping surface 13 is inserted to support the spring 12. Next, the hook rod 14 is inserted from the bottom of the damping surface 13 and coupled to pass through the center of the spring 12 to the upper portion of the housing 11. The stopper 1 is fixed to the upper portion of the hook rod 14 while pulling the hook rod 14 to allow the spring 12 to fully enter the housing 11 in a compressed state. In this way, the spring 12 continues to be compressed. Thereafter, the hook rod 14 is coupled to the outer body 100 with a pin 15.

상기와 같은 본 고안의 세탁기 현가장치는 스톱퍼(1)를 이용하여 스프링(12)을 압축시켜 놓았기 때문에 진동에 따른 스프링(12)의 변위는 크지만 최소 하중과 최대 하중의 변위 차가 적어진다. 즉, 최소 하중으로 세탁과 탈수를 하여도 스프링(12)이 이에 적절한 진동의 흡수 및 완충기능을 수행할 수 있게 되는 것이다.The washing machine suspension device of the present invention as described above has a large displacement of the spring 12 due to vibration because the spring 12 is compressed using the stopper 1, but the difference in displacement between the minimum load and the maximum load is small. That is, even if the washing and dehydration with a minimum load spring 12 is able to perform the appropriate vibration absorption and buffering function.

또한, 탄성계수가 적은 스프링(12)을 이용하므로 진동에 따른 운동이 부드러워져 소음을 줄일 수 있다.In addition, since the spring 12 having a small modulus of elasticity is used, the movement caused by vibration is softened, thereby reducing noise.
