Description

세탁기의 현가장치Suspension of washing machine

본 고안은 세탁기의 현가장치에 관한 것으로, 더욱 상세하게는 세탁기 현가장치에 적용되어지는 탄성스프링의 상·하부 직경을 서로 상이하게 구성함으로서 세탁 및 탈수행정시 저수조에 차등적으로 발생하는 진동량에 관계없이 저수조의 진동을 효율적으로 감쇄시켜줄 수 있도록 한 세탁기의 현가장치에 관한 것이다.The present invention relates to a suspension device for a washing machine. More specifically, the upper and lower diameters of elastic springs applied to a washing machine suspension device are configured differently so that the amount of vibration differentially generated in the water storage tank during washing and dehydration administration is provided. Regardless, the present invention relates to a suspension device for a washing machine capable of efficiently attenuating vibrations of a water tank.

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 소멸시켜주어 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 shake tank 50 is shaken in the housing 20 The compressed elastic spring 30 is compressed or expanded to absorb the vibration as well as to 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 하우징(20)내에 삽입되어 저수조(50)의 진동을 흡수하기 위한 탄성스프링(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 elastic spring 30 for absorbing the vibration of the reservoir 50, because the diameters are all the same, the constant of the spring to influence the elastic force of the spring Will work the same.

따라서 세탁 및 탈수시에 저수조(50)에 발생되는 진동은 그 진동량에 차이가 있음에도 불구하고 상기 탄성스프링(30)의 동일한 스프링 상수에 의해 탄성력이 동일하게 작용하게 되므로서 최적의 진동 억제효과를 가져올 수 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 elastic spring 30, thereby providing an optimal vibration suppression effect. There was a drawback that could not be brought.

이에 본 고안은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 고안은 세탁과 탈수 과정에서 발생되는 저수조의 진동량에 차등이 있더라도 상기 차등 발생되는 진동을 효율적으로 흡수할 수 있도록 하여 진동으로 인한 소음의 발생을 감소시켜주고 저수조의 언발란스를 바로잡아주어 세탁기의 사용수명을 배가시켜줄 수 있도록 한 세탁기의 현가장치를 제공하는데 그 목적이 있는 것이다.Thus, the present invention is devised to solve the above problems, the present invention, even if there is a difference in the amount of vibration of the reservoir generated during the washing and dehydration process to efficiently absorb the vibration generated by the vibration caused by the vibration It is an object of the present invention to provide a suspension device for a washing machine that reduces the occurrence of noise and corrects the unbalance of a water tank, thereby doubling the service life of the washing machine.

상기의 목적을 달성시키기 위한 본 고안에 따른 세탁기의 현가장치는 세탁기의 현가장치에 적용되는 탄성스프링의 상·하직경을 서로 달리 구성하여 저수조의 차등된 진동량에 따라 탄성스프링의 압축이 탄성스프링의 하부직경으로부터 단계적으로 이루어지도록 하여 저수조의 진동 흡수효율을 배가시킬 수 있도록 한 것에 그 특징이 있다.Suspension device of the washing machine according to the present invention for achieving the above object is configured by differently configuring the upper and lower diameter of the elastic spring applied to the suspension device of the washing machine to compress the elastic spring according to the differential vibration amount of the reservoir It is characterized by being able to double the vibration absorption efficiency of the reservoir by being made step by step from the lower diameter of.

본 고안에 따른 세탁기의 현가장치는 세탁기의 현가장치에 적용되는 탄성스프링(120)의 상·하부직경을 서로 달리 구성하여 세탁기의 저수조(50)가 세탁 또는 탈수 과정에서 진동량이 차등적으로 발생되어질 때 그 차등된 진동량에 따라 탄성스프링(120)의 압축이 하부직경(150)으로부터 단계적으로 이루어지도록 하여 세탁기 저수조(50)의 진동 흡수효율을 배가시킬 수 있도록 한 것이다.Suspension device of the washing machine according to the present invention is configured so that the upper and lower diameter of the elastic spring 120 is applied to the suspension device of the washing machine to be differently generated in the water storage tank 50 of the washing machine during the washing or dehydration process. At this time, the compression of the elastic spring 120 is made in stages from the lower diameter 150 according to the differential vibration amount so as to double the vibration absorption efficiency of the washing machine reservoir 50.

상기 탄성스프링(120)의 상부직경(140)은 탄성스프링(120)의 선단과 동일한 직경으로 구성되고 그 하부의 하부직경(150)은 상부직경(140)에 비해 그 직경이 약 절반 정도로 협소하게 구성된 것이다.The upper diameter 140 of the elastic spring 120 is composed of the same diameter as the front end of the elastic spring 120 and the lower diameter 150 of the lower than the upper diameter 140 narrowly about half the diameter It is composed.

상기와 같이 구성되어진 본 고안은 저수조(50)의 하단 외주면에 결합되는 것이고 세탁기의 세탁이나 탈수 과정에서 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 탄성스프링(120)의 상부를 압부하게 되는 것이며, 동시에 걸이봉(110)의 하단에 고정결합된 밀폐판(130)에 의해 탄성스프링(120)이 압착되어져 저수조(50)에 발생된 진동이 신속하게 흡수됨과 아울러 진동에 의해 눌려져 있던 상기 탄성스프링(120)은 그 형태복원력에 의해 저수조(50)가 기울어진 방향의 반대쪽으로 힘이 작용함으로서 저수조(50)의 언발란스가 순간적으로 잡혀지게 되는 것이다.The present invention is configured as described above is coupled to the outer peripheral surface of the bottom of the reservoir 50 and the reservoir 50 in the predetermined direction by the vibration generated by the vibration generated in the reservoir 50 during the washing or dehydration process of the washing machine When inclined, the housing 100 is pressed downward with the reservoir 50 to press the upper portion of the elastic spring 120 accommodated therein, and at the same time, the sealing plate fixedly coupled to the lower end of the hook rod 110. The elastic spring 120 is squeezed by the 130 to quickly absorb the vibration generated in the reservoir 50 and the elastic spring 120, which was pressed by the vibration, is inclined by the shape restoring force. As the force acts on the opposite side of the turning direction, the unbalance of the reservoir 50 is taken at a moment.

한편, 본 고안은 밀폐판(130)과 접촉되어지는 상기 탄성스프링(120)은 그 하부직경(150)이 상부직경(140)에 비해 상대적으로 협소하기 때문에 예컨대 저수조(50)내에 담수된 세탁수가 없게 되는 탈수행정시에는 저수조(50)의 하중이 세탁행정시보다는 상대적으로 적어 그만큼 저수조(50)에 가해지는 부하가 적어지게 되므로 탄성스프링(120)은 이에 상응하는 만큼의 탄성력이 작용하게 되는 것이다.On the other hand, the present invention is the elastic spring 120 is in contact with the sealing plate 130 is because the lower diameter 150 is relatively narrow compared to the upper diameter 140, for example, the wash water fresh in the reservoir 50 In the case of no dehydration stroke, the load of the reservoir 50 is relatively less than the washing stroke, so that the load on the reservoir 50 is less, so that the elastic spring 120 acts as a corresponding elastic force. .

즉, 첨부도면 도 3a에 도시된 바와 같이 탈수시에는 저수조(50)에 발생되는 부하량이 적어 탄성스프링(120)의 전체가 압착되지 않고 탄성스프링(120)의 하부직경(150)만이 선택적으로 밀폐판(130)의 상면에 밀착되어진 상태에서 탄성스프링(120)에 발생되어진 하중만큼 압착되어지므로 탄성스프링(120)의 상·하길이방향 전체에 탄성력이 작용하게 되는 것이다.That is, as shown in FIG. 3A, when dewatering, the load generated in the water storage tank 50 is small so that the entire elastic spring 120 is not compressed, and only the lower diameter 150 of the elastic spring 120 is selectively sealed. Since it is pressed as much as the load generated in the elastic spring 120 in the state in close contact with the upper surface of the plate 130, the elastic force acts on the entire upper and lower length direction of the elastic spring 120.

또한, 세탁기의 세탁행정시 저수조(50)내에 세탁수가 담겨지게 되면 담수된 세탁수의 무게에 의해 저수조(50)에 발생되는 부하량이 세탁기의 탈수행정시보다 상대적으로 증가하게 되므로 첨부도면 도 3b에 도시된 바와 같이 탄성스프링(120)의 하부직경(150)만이 아닌 상부직경(140)의 일부까지 밀폐판(130)에 의해 압착됨으로서 압착되지 않은 상기 상부직경(140)의 일부에만 탄성력이 작용하게 되는 것이다.In addition, when the washing water is contained in the water storage tank 50 during the washing operation of the washing machine, the load generated in the water storage tank 50 by the weight of the fresh water is relatively increased than during the dehydration administration of the washing machine. As shown in the drawing, not only the lower diameter 150 of the elastic spring 120 but also a portion of the upper diameter 140 is compressed by the sealing plate 130 so that the elastic force acts only on a portion of the upper diameter 140 which is not compressed. Will be.

본 고안에 따른 세탁기의 현가장치는 세탁기의 현가장치에 적용되는 탄성스프링의 상·하직경을 서로 달리 구성하여 세탁기의 저수조가 세탁 또는 탈수 과정에서 진동량이 차등적으로 발생되어질 때 그 차등된 진동량에 따라 탄성스프링의 압착이 단계적으로 이루어지도록 하여 세탁기의 세탁과 탈수 과정에서 발생되는 저수조의 진동량에 차등이 있더라도 상기 세탁과 탈수 과정에서 발생되는 진동이 효율적으로 흡수되어 저수조의 진동으로 인한 소음의 발생을 감소시켜주고 저수조의 언발란스를 바로잡아주어 세탁기의 사용수명을 배가시켜줄 수 있는 효과가 있는 것이다.Suspension device of the washing machine according to the present invention is configured by differently configuring the upper and lower diameters of the elastic spring applied to the suspension device of the washing machine, the differential vibration amount when the water storage tank of the washing machine is differentially generated during the washing or dehydration process According to this step, the compression of the elastic spring is performed step by step, so even if there is a difference in the amount of vibration generated in the washing and dehydrating process of the washing machine, the vibration generated in the washing and dehydrating process is efficiently absorbed, thereby reducing the noise caused by the vibration of the reservoir. It is effective in reducing the occurrence and correcting the unbalance of the reservoir to double the service life of the washing machine.
