Description

세탁기의 현가장치Suspension of washing machine

본 고안은 세탁기의 현가장치에 관한 것으로, 더욱 상세하게는 세탁기 현가장치에 적용되어지는 스프링을 압축스프링의 내주면에 인장스프링을 결합시켜 세탁기의 세탁 및 탈수행정시 저수조에 차등적으로 발생하는 진동량에 관계없이 저수조의 진동을 효율적으로 감쇄시켜줄수 있도록 하고 또한, 세탁수의 무게에 의해 부하가 많이 발생하는 세탁기의 세탁행정시 상기 인장스프링의 작용으로 압축스프링이 압축되는 폭을 상대적으로 줄일수 있도록 하여 세탁기의 높이 치수를 줄여 줄수 있도록 한 세탁기의 현가장치에 관한 것이다.The present invention relates to a suspension device for a washing machine. More specifically, a spring applied to a washing machine suspension device is coupled to a tension spring on an inner circumferential surface of a compression spring, and the vibration amount differentially generated in the water storage tank during washing and dehydration operation of the washing machine. Irrespective of the vibration of the water tank, it is possible to effectively reduce the vibration, and to reduce the width of the compression spring compressed by the action of the tension spring during the washing stroke of the washing machine, in which a lot of load is generated by the weight of the washing water. It relates to a suspension of the washing machine to reduce the height dimension of the washing machine.

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

이러한 종래의 현가장치는 도1에 도시된 바와같이 걸이봉(10)이 관통되고 하부가 개방된 하우징(20)의 내부에 압축스프링(30)이 내장되고, 상기 하우징(20)을 관통한 걸이봉(10)의 끝단부에 압축스프링(30)이 탄지된 상태로 하여 밀폐판(40)이 끼워지고 이의 선단에는 너트(45)가 결합되는 구조이다.As shown in FIG. 1, a conventional suspension device includes a compression spring 30 embedded in a housing 20 through which a hanger rod 10 is opened and a lower portion thereof, and a hook passing through the housing 20. The sealing spring 40 is fitted in the state in which the compression 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 압축스프링(30)이 압축되어지게 된다.Therefore, the suspension device is a washing spring in which 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 compression spring held on the 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 압축스프링(30)이 압축 또는 팽창되면서 그 진동을 흡수함과 아울러 이를 소멸시켜주어 세탁시 저수조(50)의 진동에 의한 소음의 발생을 극소화 시키고 저수조(50)의 언 발란스를 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 spring 30 is compressed or expanded to absorb the vibration and extinguish it, thereby minimizing the occurrence of noise due to the vibration of the reservoir 50 during washing and holding the unbalance of the reservoir 50. Will be.

그러나 상기와 같은 종래의 현가장치는 하우징(20)내에 삽입되어 저수조(50)의 진동을 흡수하기 위한 압축스프링(30)은 그 직경이 모두 동일한 것으로 되어 있었기 때문에 스프링의 탄성력을 좌우하는 스프링의 상수가 동일하게 작용하게 된다.However, the conventional suspension as described above is inserted into the housing 20, the compression spring (30) for absorbing the vibration of the reservoir 50, the diameter of the spring to influence the elastic force of the spring because all of the diameter is the same Will work the same.

따라서 세탁 및 탈수시에 저수조(50)에 발생되는 진동은 그 진동량에 차이가 있음에도 불구하고 상기 압축스프링(30)의 동일한 스프링 상수에 의해 탄성력이 동일하게 작용하게 되므로서 최적의 진동 억제효과를 가져올수 없는 단점이 있었다.Therefore, even when the vibration generated in the water storage tank 50 during washing and dehydration has a difference in the amount of vibration, the elastic force acts the same by the same spring constant of the compression spring 30, thereby providing the optimum vibration suppression effect. There was a disadvantage that can not be brought.

또한 저수조(50)내에 담겨진 세탁수의 무게에 의해 부하가 많이 발생하게 되는 세탁행정시에는 상기 부하량에 따라 현가장치의 압축스프링(30)이 완전히 압착되게 되므로 저수조(50)의 하향폭이 커질수 밖에 없어 이에 따라 세탁의 높이치수를 키워야하는 단점이 있었다.In addition, when the load is generated by the weight of the wash water contained in the water storage tank 50, the compression spring 30 of the suspension device is completely compressed in accordance with the load, so that the downward width of the water storage tank 50 can only be increased. There was no drawback to increase the height of the washing accordingly.

이에 본 고안은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 고안은 세탁과 탈수과정에서 발생되는 저수조의 진동량에 차등이 있더라도 상기 차등 발생되는 진동을 효율적으로 흡수할수 있도록 하여 진동으로 인한 소음의 발생을 감소시켜주고 저수조의 언발란스를 바로잡아주어 세탁기의 사용수명을 배가시켜줄수 있도록한 세탁기의 현가장치를 제공하는데 그 목적이 있는 것이며, 본 고안의 또다른 목적은 부하가 많이 발생하는 세탁기의 세탁행정시 압축스프링이 압축되는 폭을 줄여 줄수 있도록 하여 세탁기의 높이 치수를 줄일수 있도록 한 것이다.Therefore, the present invention was devised to solve the above problems, and the present invention makes it possible to efficiently absorb the vibration generated by the vibration even if the vibration amount of the reservoir generated during the washing and dehydration process is different. It is an object of the present invention to provide a suspension device for a washing machine that reduces the occurrence of water and corrects the unbalance of the water tank, thereby doubling the service life of the washing machine. It is to reduce the height of the washing machine by reducing the width of the compression spring during washing administration.

상기의 목적을 달성시키기 위한 본 고안에 따른 세탁기의 현가장치는 세탁기의 현가장치에 적용되는 스프링을 압축스프링의 내주면에 인장스프링을 결합하여 저수조에 발생되는 차등된 진동량에 따라 상기 압축스프링과 인장스프링이 선택적으로작용하여 저수조의 진동 흡수효율을 배가 시킬수 있도록 하고, 또한 부하가 많이 발생하는 세탁기의 세탁행정시 상기 인장스프링의 작용으로 압축스프링의 압축되는 폭을 상대적으로 줄일수 있도록 하여 세탁기의 높이 치수를 줄여 줄수 있도록 한 것에 그 특징이 있는 것이다.Suspension device of the washing machine according to the present invention for achieving the above object is a spring applied to the suspension device of the washing machine coupled to the tension spring to the inner circumferential surface of the compression spring by the compression spring and tension according to the differential vibration generated in the water tank The spring acts as a selective action to double the vibration absorption efficiency of the water tank, and also to relatively reduce the compression width of the compression spring by the action of the tension spring in the washing stroke of the washing machine that generates a lot of load. It is characterized by the ability to reduce the dimensions.

도2는 본 고안에 따른 현가장치의 단면도이고, 도3a은 본 고안에 따른 현가장치에 탈수시의 부하가 작용되어진 상태이며. 도3b는 본 고안에 따른 현가장치에 세탁시의 부하가 작용되어진 상태를 나타낸 것으로, 본 고안에 따른 세탁기의 현가장치는 세탁기의 현가장치에 적용되는 스프링을 압축스프링(140)의 내주면에 인장스프링(150)을 결합시켜 세탁기의 저수조(50)가 세탁 또는 탈수과정에서 진동량이 차등적으로 발생되어질 때 그 차등된 진동량에 따라 상기 압축스프링(140)과 인장스프링(150)이 선택적으로 작용하여 세탁기 저수조(50)의 진동 흡수효율을 배가 시킬수 있도록 한 것이다.Figure 2 is a cross-sectional view of the suspension device according to the present invention, Figure 3a is a state in which the load upon dehydration is applied to the suspension device according to the present invention. 3b shows a state in which a load upon washing is applied to the suspension device according to the present invention, and the suspension device of the washing machine according to the present invention has a spring applied to the suspension device of the washing machine and a tension spring on the inner circumferential surface of the compression spring 140. When the water storage tank 50 of the washing machine is coupled to each other by combining 150, the compression spring 140 and the tension spring 150 selectively act according to the differential vibration amount when the vibration amount is differentially generated during the washing or dehydration process. It is to double the vibration absorption efficiency of the washing machine reservoir (50).

한편, 상기 압축스프링(140)의 내주면에 결합되어진 인장스프링(150)은 그 선단이 하우징(100)의 선단에 밀착되는 것이며 그 하단은 밀폐판(130)과 밀착되어지는 구조이다.On the other hand, the tension spring 150 is coupled to the inner circumferential surface of the compression spring 140, the front end is in close contact with the front end of the housing 100 and the lower end is in close contact with the sealing plate 130.

상기와 같이 구성되어진 본 고안은 현가장치의 하우징(100)이 저수조(50)의 하단 외주면에 결합되는 것이고, 세탁기의 세탁이나 탈수과정에서 저수조(50)에 진동이 발생하여 발생된 진동에 의해 상기 저수조(50)가 소정의 방향으로 기울어지게 되면 하우징(100)이 저수조(50)와 함께 하부방향으로 눌려지면서 그 내부에 수용된 압축 및 인장스프링(140)(150)의 상부를 압부하게 되는 것이며, 동시에 걸이봉(110)의 하단에 고정결합된 밀폐판(130)에 의해 상기 압축 및 인장스프링(140)(150)이 압착되어져 저수조(50)에 발생된 진동이 신속하게 흡수되는 것이다.The present invention configured as described above is the housing 100 of the suspension device is coupled to the outer peripheral surface of the bottom of the reservoir 50, by the vibration generated by the vibration generated in the reservoir 50 during the washing or dehydration process of the washing machine When the reservoir 50 is inclined in a predetermined direction, the housing 100 is pressed downward along with the reservoir 50 to press the upper portion of the compression and tension springs 140 and 150 accommodated therein. At the same time, the compression and tension springs 140 and 150 are compressed by the sealing plate 130 fixedly coupled to the lower end of the hook rod 110 so that the vibration generated in the reservoir 50 is quickly absorbed.

아울러 진동에 의해 눌려져 있던 상기 압축스프링(140)은 그 형태복원력에 의해 저수조(50)가 기울어진 방향의 반대쪽으로 힘이 작용함으로서 저수조(50)의 언발란스가 순간적으로 잡혀지게 되는 것이다.In addition, the compression spring 140, which was pressed by the vibration, acts in a direction opposite to the direction in which the storage tank 50 is inclined by the shape restoring force, so that the unbalance of the storage tank 50 is temporarily caught.

한편, 본 고안은 밀폐판(130)과 접촉되어지는 상기 압축 및 인장스프링(140)(150)이 세탁기의 세탁 및 탈수시에 차등적으로 발생되는 진동량에 각각 그 작용이 다르게 나타나게 되는데, 이는 첨부도면 도3a에 도시된 바와같이 탈수시에는 저수조(50)에 발생되는 부하량이 적어 인장스프링(150)은 작동되지 않고 압축스프링(140)만이 선택적으로 압축되는 것이며. 또한, 세탁기의 세탁행정시 저수조(50)내에 세탁수가 담겨지게 되어 담수된 세탁수의 무게에 의해 저수조(50)에 발생되는 부하량이 많게되면 본 고안은 첨부도면 도3b에 도시된 바와 같이 압축스프링(140)의 내부에 결합된 인장스프링(150)의 작용으로 상기 압축스프링(140)이 완전히 압착되지가 않게 되는 것이다.On the other hand, the present invention is that the compression and tension springs 140 and 150 which are in contact with the sealing plate 130 will appear differently on the amount of vibration generated differentially during washing and dehydration of the washing machine, which is As shown in FIG. 3A, when dewatering, the load generated in the water storage tank 50 is small, so that the tension spring 150 is not operated and only the compression spring 140 is selectively compressed. In addition, the washing water is contained in the water storage tank 50 during the washing operation of the washing machine, the load is generated in the water storage tank 50 by the weight of the fresh water to wash the present invention is a compression spring as shown in Figure 3b The compression spring 140 is not fully compressed by the action of the tension spring 150 coupled to the inside of the 140.

따라서, 저수조(50)가 하향되는 폭이 크지 않게 되므로 세탁기의 상.하높이를 줄일수가 있어 세탁기의 사용(세탁후에 세탁조내에 담기게 되는 세탁물을 꺼내기가 용이해짐)이 편리해 지게 되는 것이다.Therefore, since the width of the water storage tank 50 is not large, it is possible to reduce the upper and lower heights of the washing machine, so that the use of the washing machine (easy to take out the laundry contained in the washing tank after washing) becomes convenient.

본 고안에 따른 세탁기의 현가장치는 세탁기의 현가장치에 적용되는 스프링을압축스프링의 내주면에 인장스프링을 결합하여 세탁기의 저수조가 세탁 또는 탈수과정에서 진동량이 차등적으로 발생되어질 때 그 차등된 진동량에 따라 상기 압축스프링과 탄성스프링이 선택적으로 작용하여 저수조에 발생되는 진동이 효율적으로 흡수하여 저수조의 진동으로 인한 소음의 발생을 감소시켜주고 저수조의 언발란스를 바로잡아주어 세탁기의 사용수명을 배가시켜줄수 있는 효과가 있는 것이며, 또한 부하가 많이 발생하는 세탁기의 세탁행정시 상기 인장스프링의 작용으로 압축스프링이 압축되는 폭이 줄어들게 되어 세탁기의 높이 치수를 줄여 줄수 있는 효과가 있는 것이다.Suspension device of the washing machine according to the present invention is a spring applied to the suspension device of the washing machine by combining the tension spring to the inner circumferential surface of the compression spring, the differential vibration amount when the reservoir of the washing machine is differentially generated during the washing or dehydration process According to the compression spring and the elastic spring selectively acts to effectively absorb the vibration generated in the reservoir to reduce the noise caused by the vibration of the reservoir and to correct the unbalance of the reservoir can double the service life of the washing machine In addition, there is an effect that can reduce the width of the compression spring is reduced by the compression spring by the action of the tension spring during the washing stroke of the washing machine is a lot of load is to reduce the height dimension of the washing machine.
