Description

세탁기의 현가장치Suspension of washing machine

본 고안은 세탁기의 현가장치에 관한 것으로, 더욱 상세하게는 세탁기 현가장치에 적용되어지는 탄성스프링을 저수조의 고정편에 대해 상·하 방향으로 배치하여 저수조의 상·하진동을 효율적으로 감쇄시켜 줄 수 있도록 한 세탁기의 현가장치에 관한 것이다.The present invention relates to a suspension device for a washing machine. More specifically, an elastic spring applied to a washing machine suspension device is disposed in an up and down direction with respect to a fixing piece of a water tank to effectively reduce the up and down vibration of the water tank. It relates to a suspension of a washing machine.

일반적으로 세탁기에 적용되어진 현가장치는 세탁기 외체의 내부에 위치하는 저수조를 걸어둘 수 있도록 함과 아울러 세탁행정도중 발생된 진동을 효율적으로 완충시켜 줄 수 있도록 된 것이다.In general, the suspension system applied to the washing machine is able to hang the water tank located inside the washing machine's outer body and to efficiently absorb the vibration generated during the washing run.

이러한 종래의 현가장치는 도 1에 도시된 바와 같이 걸이봉(10)이 관통되고 하부가 개방된 하우징(20)의 내부에 탄성스프링(30)이 내장되고, 상기 하우징(20)을 관통한 걸이봉(10)의 끝단부에 탄성스프링(30)이 탄지된 상태로 하여 밀폐판(40)이 끼워지고 이의 선단에는 너트(45)가 결합된 구조이다.As shown in FIG. 1, the conventional suspension device includes an elastic spring 30 embedded in a housing 20 through which a hanger rod 10 is passed through and a lower portion thereof, and a hook passing through the housing 20. The sealing plate 40 is fitted in the state in which the elastic spring 30 is held on the end of the rod 10, and the nut 45 is coupled to the front end thereof.

따라서 상기 현가장치는 세탁기의 저수조(50)내에 세탁수가 담수되게 되면 그 중량에 의해 저수조(50)가 하향되면서 하우징(20)내에 내장된 상태에서 이의 상면과 밀폐판(40)에 탄지된 탄성스프링(30)이 압축되어지게 된다.Therefore, the suspension device is when the wash water is fresh water in the water storage tank 50 of the washing machine while the water storage tank 50 is lowered by its weight while being embedded in the housing 20, the elastic spring supported on its upper surface and the sealing plate 40 30 is compressed.

상기와 같은 상태에서 세탁행정시 구동부의 구동에 의한 진동 및 세탁수와 세탁물의 회류에 의해 발생된 진동력이 저수조(50)로 전달되어 저수조(50)가 흔들리게 되면 상기 하우징(20)내부에서 압축되어 있는 탄성스프링(30)이 압축 또는 팽창되면서 그 진동을 흡수함과 아울러 이를 소멸시켜 주어 세탁시 저수조(50)의 진동에 의한 소음의 발생을 극소화시키고 저수조의 언발란스를 잡아주게 되는 것이다.Vibration force generated by the driving of the driving unit during the washing stroke and the rotation of the wash water and the laundry in the above state is transmitted to the reservoir 50, the reservoir 50 is shaken in the housing 20 The compressed elastic spring 30 is compressed or expanded to absorb the vibration and extinguish it, thereby minimizing the generation of noise due to the vibration of the water storage tank 50 and washing the unbalance of the water storage tank.

그러나 상기와 같은 종래의 현가장치는 걸이봉(10)이 하부방향으로 힘을 받을 경우에만 하우징(20)내에 삽입된 탄성스프링(30)이 하방으로 압축되면서 진동을 흡수하기 때문에 예컨대, 저수조(50)가 상부방향으로 진동될 경우에는 상기 하우징(20)내에 삽입된 탄성스프링(30)이 압착되지 않아 발생된 진동을 흡수하지 못하여 진동의 흡수효율이 떨어지게 되는 문제점이 있었다.However, the conventional suspension device as described above, for example, because the elastic spring 30 inserted into the housing 20 is compressed downward to absorb the vibration only when the hook rod 10 receives a force in the downward direction, for example, the reservoir 50 In the case of vibrating in an upward direction, the elastic spring 30 inserted into the housing 20 is not compressed and thus does not absorb the generated vibration, thereby lowering the absorption efficiency of the vibration.

이에 본 고안은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 고안은 저수조의 하부방향만이 아닌 저수조의 상부방향으로 발생된 진동을 효율적으로 감쇄시켜 줄 수 있도록 하여 진동으로 인한 소음의 발생을 감소시켜 주고 저수조의 언발란스를 바로잡아주어 세탁기의 사용수명을 배가시켜 줄 수 있도록 한 세탁기의 현가장치를 제공하는데 그 목적이 있는 것이다.The present invention is devised to solve the above problems, the present invention can efficiently attenuate the vibration generated in the upper direction of the reservoir as well as the lower direction of the reservoir to prevent the generation of noise due to vibration The purpose of the present invention is to provide a suspension of the washing machine, which reduces and corrects the unbalance of the reservoir, thereby doubling the service life of the washing machine.

상기의 목적을 달성시키기 위한 본 고안에 따른 세탁기의 현가장치는 세탁기 현가장치에 적용되어지는 탄성스프링을 저수조의 고정편에 대해 상·하 방향으로 배치하여 상기 저수조가 상·하부 방향으로 진동되어질 때 고정편의 상·하 방향에 배치된 상기 탄성스프링이 선택적으로 압착되어지면서 진동을 흡수할 수 있도록 한 것에 그 특징이 있는 것이다.Suspension device of the washing machine according to the present invention for achieving the above object is to place the elastic spring applied to the washing machine suspension device in the up and down direction with respect to the fixing piece of the water tank when the water tank is vibrated in the up and down direction The elastic spring disposed in the up and down direction of the fixing piece is characterized in that it is capable of absorbing vibration while being selectively compressed.

도 2는 본 고안에 따른 현가장치의 확대단면도이며, 도 3은 본 고안에 따른 현가장치의 작동상태를 나타낸 것으로, 본 고안에 따른 세탁기의 현가장치(A)는 세탁기 현가장치에 적용되어지는 탄성스프링(120)을 저수조(50)의 고정편(60)에 대해 상·하 방향으로 배치하여 상기 저수조(50)가 상·하 방향으로 진동되어질 때 고정편(60)의 상·하 방향에 배치된 상기 탄성스프링(120)이 선택적으로 압착되어지면서 진동을 효율적으로 흡수할 수 있도록 한 것이다.Figure 2 is an enlarged cross-sectional view of the suspension device according to the present invention, Figure 3 shows the operating state of the suspension device according to the present invention, the suspension device (A) of the washing machine according to the present invention is elastically applied to the washing machine suspension device The spring 120 is disposed in the up and down direction with respect to the fixing piece 60 of the water tank 50, and is disposed in the up and down direction of the fixing piece 60 when the water tank 50 is vibrated in the up and down direction. The elastic spring 120 is to be selectively compressed to absorb the vibration efficiently.

상기 탄성스프링(120)은 저수조(50)의 고정편(60)에 상·하 방향으로 배치된 상·하부하우징(100)(110)내에 각각 삽입되는 것이고, 상기 상·하부하우징(100)(110)의 상·하단에는 상·하부밀폐판(130)(140)이 걸이봉(10)의 외주면에 나사결합되는 너트에 의해 탄성스프링(120)과 탄지되어진 상태로 밀착된 것이다.The elastic spring 120 is inserted into each of the upper and lower housings 100 and 110 disposed in the up and down directions on the fixing piece 60 of the water storage tank 50, and the upper and lower housings 100 ( The upper and lower sealing plates 110 and 140 are in close contact with the elastic spring 120 by a nut that is screwed to the outer circumferential surface of the hook rod 10.

상기 상부하우징(100)의 하부는 고정편(60)의 상면과 밀착될 수 있도록 만곡형상으로 구성되고, 하부하우징(110)의 상부는 고정편(50)의 중앙에 형성된 관통공(70)내에 그 일부가 삽입고정되는 것이며 상기 걸이봉(10)은 상·하부하우징(100)(110)과 저수조(50)의 관통공(70)내를 수직으로 관통하는 구조이다.The lower portion of the upper housing 100 has a curved shape to be in close contact with the upper surface of the fixing piece 60, the upper portion of the lower housing 110 in the through hole 70 formed in the center of the fixing piece 50 A part of which is inserted and fixed, and the hook rod 10 has a structure that vertically penetrates the inside of the through hole 70 of the upper and lower housings 100 and 110 and the reservoir 50.

상기와 같이 구성되어진 본 고안은, 도 3에 도시된 바와 같이 세탁시에 발생된 진동에 의해 저수조(50)가 일측으로 기울어지게 되면 저수조(50)의 하단 외주면에 형성된 고정편(60)에 상·하 방향으로 배치된 탄성스프링(120)이 선택적으로 압착되면서 발생된 진동이 감쇄되는 것이다.The present invention is constructed as described above, when the reservoir 50 is inclined to one side by the vibration generated during washing as shown in Figure 3 on the fixing piece 60 formed on the outer peripheral surface of the lower end of the reservoir 50 Vibration generated as the elastic spring 120 disposed in the downward direction is selectively compressed to be attenuated.

즉, 도면에 도시된 바와 같이 저수조(50)가 하부방향으로 진동되어진 쪽에 장착되어진 현가장치는 그 진동에 의해 하부방향으로 위치 이동되어진 저수조(50)의 고정편(60)이 그 하부에 배치된 하부하우징(110)을 압착하게 되고 동시에 그 내부에 삽입된 탄성스프링(120)이 상기 하부하우징(110)의 상부 내벽에 의해 하방으로 눌려지게 되면서 충격을 흡수하여 진동이 감쇄되어지는 것이다.That is, as shown in the drawing, the suspension device mounted on the side in which the reservoir 50 is vibrated in the lower direction has the fixing piece 60 of the reservoir 50 positioned in the lower direction by the vibration thereof. At the same time, the lower housing 110 is compressed and the elastic spring 120 inserted therein is pressed downward by the upper inner wall of the lower housing 110 to absorb the shock and thus reduce vibration.

또한, 상기 저수조(50)가 상부 방향으로 들려진 쪽에 위치한 현가장치에 있어서는 저수조(50)와 함께 상승되는 고정편(60)이 그 상부방향에 배치된 상부하우징(100)의 저면을 들어올리게 되고 이와 동시에 상부하우징(100)내에 장착된 탄성스프링(120)이 압착되면서 발생된 진동을 흡수하게 된다.In addition, in the suspension device located on the side in which the reservoir 50 is lifted in the upper direction, the fixing piece 60 which rises together with the reservoir 50 lifts the bottom surface of the upper housing 100 arranged in the upper direction thereof. At the same time, the elastic spring 120 mounted in the upper housing 100 absorbs the vibration generated by the compression.

한편, 상기 탄성스프링(120)이 상·하부하우징(100)(110)에 의해 압착될 수 있는 것은 걸이봉(10)의 외주면에 너트를 통하여 고정결합된 상·하부밀폐판(130)(140)이 상기 탄성스프링(120)에 밀착되어 있기 때문이며, 또한 고정편(60)의 상·하면이 만곡부로 구성되고 그 중앙에는 관통공(70)이 형성되어 이 관통공(70)내에 하부하우징(110)의 상부가 끼움결합되고 상기 상부하우징(100)의 바닥면은 고정편(60)의 상면에 긴밀하게 밀착되므로 고정편(60)에 대해 상·하부하우징(100)(110)이 이탈되지 않아 저수조(50)의 진동을 효과적으로 감쇄시킬 수가 있게 된다.On the other hand, the elastic spring 120 can be compressed by the upper and lower housings 100, 110 is the upper and lower sealing plate 130, 140 fixedly coupled to the outer circumferential surface of the hook rod 10 through a nut. ) Is in close contact with the elastic spring 120, and the upper and lower surfaces of the fixing piece 60 is formed with a curved portion, and a through hole 70 is formed at the center thereof, and a lower housing (in the through hole 70) is formed. The upper part of the 110 is fitted and the bottom surface of the upper housing 100 is in close contact with the upper surface of the fixing piece 60 so that the upper and lower housings 100 and 110 are not separated from the fixing piece 60. Therefore, the vibration of the reservoir 50 can be effectively attenuated.

상기와 같이 저수조(50)의 상·하 방향에 진동을 흡수하기 위한 탄성스프링(120)이 각각 장착되어 상기 탄성스프링(120)이 저수조(50)가 기울어진 방향에 대해 압착되면서 그 진동을 양방향에서 신속하게 흡수함과 아울러 진동에 의해 눌려져 있던 상기 탄성스프링(120)의 형태복원력에 의해 저수조(50)가 기울어진 방향의 반대쪽으로 힘이 작용하여 저수조(50)의 언발란스가 순간적으로 잡혀지게 되는 것이다.As described above, the elastic springs 120 for absorbing vibrations are respectively mounted in the up and down directions of the water storage tank 50 so that the elastic springs 120 are compressed against the inclined direction of the water storage tank 50 so that the vibrations are bidirectional. Absorption of the water tank 50 is instantaneously absorbed by the force in the opposite direction of the direction in which the water tank 50 is inclined by the form restoring force of the elastic spring 120 which is absorbed quickly by the vibration. will be.
