Description
본 고안은 세탁기의 현가장치에 관한 것으로, 더욱 상세하게는 세탁기의 저수조 와 외체사이에 장착되는 현가장치의 댐핑력을 세탁기의 용량에 맞게 조절시킬수 있도록 하여 모든 세탁기에 범용적으로 적용시킬수 있도록 하고, 또한 세탁기에 장착되어진 부품이 비대칭으로 장착됨으로 인하여 발생되는 현가장치의 편중현상을 균형적으로 잡아 줄수 있도록 하여 현가장치의 진동흡수 효율을 극대화시킬수 있도록 한 세탁기의 현가장치에 관한 것이다.The present invention relates to a suspension device for a washing machine. More specifically, the damping force of the suspension device installed between the water tank of the washing machine and the outer body can be adjusted according to the capacity of the washing machine so that it can be universally applied to all washing machines. The present invention also relates to a suspension of a washing machine, which can maximize the vibration absorption efficiency of the suspension by balancing the bias of the suspension caused by asymmetrical mounting of the components mounted on the washing machine.
일반적으로 펄세이터 방식의 세탁기에 적용되어지는 세탁기의 현가장치는, 세탁기 외체의 상부방향으로 부터 저수조의 하부둘레에 대각선방향으로 각각 장착되어져 세탁기의 세탁 및 헹굼 그리고 탈수행정시에 상기 저수조에 전달되어지는 진동을 흡수하여 세탁기의 외체로 진동이 전달되는 것을 방지하는 기능을 수행하게 되는 것이다.In general, the suspension of the washing machine, which is applied to a washing machine of a pulsator type, is mounted on the lower periphery of the water tank diagonally from the upper direction of the washing machine's outer body to be delivered to the water tank during washing, rinsing and dehydration of the washing machine. Losing the vibration is to perform the function of preventing the vibration is transmitted to the outside of the washing machine.
한편, 세탁기에 적용되어지는 종래의 현가장치(30)는, 첨부된 도면의 도1에 도시된 바와같이 세탁기 외체(미도시함)의 상부방향으로 부터 저수조(10)의 하부둘레 방향으로 걸이봉(40)이 각각 장착되는 것이며, 상기 걸이봉(40)의 하단은 내부에 탄성스프링(70)이 수용되어진 하부징(60)의 상부구멍(80)을 관통하여 상기 탄성스프링(70)의 저면에 밀착되는 밀착판(90)에 결합나사(100)를 매개로 결합되는 것이다. 또한, 상기 하부징(60)은 그 상부면이 상기 저수조(10)의 하부둘레에 소정의 배치간격을 두고 형성되어진 걸이구(50)의 하부에 선택적으로 걸쳐지게 됨으로서, 걸이봉(40)이 상기 저수조(10)를 전체적으로 지지하는 상태에서 저수조(10)에 진동이 발생하게 되면, 상기 발생되어진 진동량에 비례하여 현가장치(30)의 하우징(60)내에 수용된 탄성스프링(70)이 걸이봉(40)의 하단에 결합된 밀착판(90)에 의해 압축됨과 동시에 상기 하우징(60)내의 공기가 압축되어지면서 그에 상응하는 댐핑력이 발생하게 되어 세탁기의 진동을 흡수할 수가 있게 되는 것이다.On the other hand, the conventional suspension device 30 is applied to the washing machine, as shown in Figure 1 of the accompanying drawings hanger rod in the direction of the lower circumference of the reservoir 10 from the upper direction of the washing machine outer body (not shown) 40 is respectively mounted, the lower end of the hanger rod 40 passes through the upper hole 80 of the lower jaw 60, the elastic spring 70 is accommodated therein, the bottom surface of the elastic spring 70 It is to be coupled via a coupling screw 100 to the close contact plate 90 to be in close contact with. In addition, the lower rod 60 is the upper surface is selectively hanged on the lower portion of the hook 50 is formed at a predetermined interval between the lower circumference of the reservoir 10, the hook rod 40 is When vibration occurs in the reservoir 10 while supporting the reservoir 10 as a whole, the elastic spring 70 accommodated in the housing 60 of the suspension device 30 in proportion to the generated vibration amount is a rod. At the same time as being compressed by the contact plate 90 coupled to the lower end of the 40, the air in the housing 60 is compressed and a corresponding damping force is generated to absorb the vibration of the washing machine.
그러나, 상기 종래의 현가장치(30)는 구조적으로 하우징(60)내의 탄성스프링(70)이 밀착판(90)에 의해 압축되면서 발생하게 되는 댐핑력을 효율적으로 조절시킬수가 없는 단점이 있다.However, the conventional suspension device 30 has a disadvantage in that it cannot structurally control the damping force generated while the elastic spring 70 in the housing 60 is compressed by the contact plate 90.
따라서 세탁물을 세탁시킬수 있는 용량에 따라 다양한 형태로 제작되는 세탁기에 상기 현가장치(30)를 공통적으로 적용시킬수가 없어 세탁기의 조립공정에 있어서 그만큼 세탁기의 조립효율이 떨어지게 되는 단점이 있는 것이다.Therefore, the suspension device 30 cannot be commonly applied to a washing machine manufactured in various forms according to the capacity for washing laundry, and thus, the assembly efficiency of the washing machine is reduced in the assembling process of the washing machine.
또한, 상기 세탁기의 저수조(10)하부에 조립되어지는 구동모터(미도시함)는 상기 저수조(10)의 일측방향에 편심되는 상태로 조립되는 것이기 때문에, 상기 저수조에 가해지는 하중에 편차가 발생되는 것이며 따라서 상기 저수조(10)와 세탁기의 외체사이에 장착되게 되는 각각의 현가장치(30)에 가해지는 하중이 다르게 작용하게 된다.In addition, since the driving motor (not shown) to be assembled under the reservoir 10 of the washing machine is assembled in a state eccentric to one side of the reservoir 10, a deviation occurs in the load applied to the reservoir. Therefore, the load applied to each of the suspension devices 30 to be mounted between the water tank 10 and the outer body of the washing machine acts differently.
그러므로 상기 각각의 현가장치(30)는, 동일한 하중이 작용하지 않게 됨으로서 세탁기의 작동과정에서 발생되는 진동을 동일한 조건하에서 효율적으로 감쇄시켜줄수 없다는 문제점이 있는 것이다.Therefore, each of the suspension device 30, there is a problem that can not effectively attenuate the vibration generated in the operating process of the washing machine under the same conditions because the same load is not applied.
이에 본 고안은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 고안은 세탁기의 저수조와 외체사이에 장착되는 현가장치의 댐핑력을 세탁기의 용량에 맞게 조절시킬수 있도록 하여 모든 세탁기에 범용적으로 적용시킬수 있도록 하고, 또한 세탁기에 장착되어진 부품이 비대칭으로 장착됨으로 인하여 발생되는 현가장치의 편하중을 균형적으로 잡아 줄수 있도록 하여 현가장치의 진동흡수 효율을 극대화시킬수 있도록 한 세탁기의 현가장치를 제공하는데 그 목적이 있는 것이다.The present invention has been devised to solve the above problems, the present invention can be applied to all washing machines by adjusting the damping force of the suspension device mounted between the reservoir and the outer body of the washing machine to the capacity of the washing machine. It also provides the suspension of the washing machine to maximize the vibration absorption efficiency of the suspension by making it possible to balance the load of the suspension caused by the asymmetrical mounting of the parts mounted on the washing machine. There is a purpose.
상기의 목적을 달성시키기 위한 본 고안에 따른 세탁기의 현가장치는, 세탁기의 외체와 저수조사이에 현가장치를 각각 장착시키되, 상기 각각의 현가장치에 적용되어지는 하우징의 하부에 덮개판이 결합된 위치에 따라 댐핑력을 조절할수 있도록 하는 커버가 부착되도록 한 것을 특징으로 한다.Suspension device of the washing machine according to the present invention for achieving the above object, the suspension device is mounted on the outer body and the water irradiator of the washing machine, respectively, in the position where the cover plate is coupled to the lower portion of the housing to be applied to the respective suspension devices It is characterized in that the cover is attached so that the damping force can be adjusted accordingly.

In the outer circumferential direction of the 120, a fan-shaped cutout 150 is formed so that the handle 160 formed on the cover plate 130 in the cutout 150 is slidably inserted so that the cover plate 130 is formed. It is possible to change the coupling position of.
한편, 상기 덮개판(130)의 저면과 그 내주면에 결합되어진 커버(110)는 그 중심부에 결합핀(140)이 결합됨으로서 상기 결합핀(140)을 중심축으로 하여 상기 커버(110)에 형성되어진 공간부(120)에 대해 덮개판(130)의 위치를 가변시킬수 있어 커버(110)상에 형성되어진 공간부(120)을 개폐시킬수 있도록 한 것이다.On the other hand, the cover 110 is coupled to the bottom surface and the inner circumferential surface of the cover plate 130 is formed in the cover 110 by the coupling pin 140 is coupled to the center of the coupling pin 140 as a central axis The position of the cover plate 130 may be varied with respect to the space portion 120 that is formed so as to open and close the space portion 120 formed on the cover 110.
상기와 같이 구성되어진 본 고안은. 하우징(60)의 하부에 커버(110)가 장착되고 또한, 상기 커버(110)에 형성되어진 공간부(120)는 그 상면에 밀착되어진 덮개판(130)에 의해 크기를 가변시킬수 있도록 함으로서 현가장치(200)의 댐핑력을 조절시킬수가 있게 되는 것이다.The present invention is configured as described above. The cover 110 is mounted on the lower portion of the housing 60, and the space part 120 formed on the cover 110 can be varied in size by the cover plate 130 which is in close contact with the upper surface thereof. The damping force of the 200 will be able to be adjusted.
즉, 본 고안은 세탁기의 조립공정시에 세탁기의 용량에 맞게 현가장치의 댐핑력을 조절시킬 경우나 혹은 세탁기에 적용되어진 부품이 비대칭으로 결합됨으로서 발생되는 세탁기의 불균형(구동장치의 구동모터가 세탁기의 저수조 일측부분에 장착되기 때문에 상기 구동모터가 장착된 부분으로 하중이 크게 작용하게 되는 것임)을 보상시키기 위해 현가장치의 댐핑력을 조절시킬 필요성이 있을때, 상기 현가장치(200)의 커버(110)에 장착되어진 덮개판(130)을 통하여 공간부(120)의 크기를 가변시킴으로서 현가장치(200)의 댐핑력을 조절시킬수가 있게 되는 것이다.That is, the present invention is an imbalance of the washing machine caused by adjusting the damping force of the suspension device according to the capacity of the washing machine in the assembling process of the washing machine or by asymmetrical coupling of the components applied to the washing machine (the driving motor of the driving device is When it is necessary to adjust the damping force of the suspension device in order to compensate the load) is mounted on one side of the reservoir of the drive motor is mounted largely), the cover 110 of the suspension device 200 By varying the size of the space 120 through the cover plate 130 mounted on the) it is possible to adjust the damping force of the suspension device (200).
한편, 상기 덮개판(130)을 통하여 커버(110)에 형성되어진 공간부(120)의 크기가 가변됨으로서 현가장치(200)의 댐핑력이 가변될수 있는 것은 예컨데, 외부로 노출되어진 손잡이(160)를 매개로 절개부(150)를 따라 위치이동시켜 상기 커버(110)에 형성되어진 공간부(120)를 완전밀폐시키거나 혹은 부분적으로 개방시키게 되면 상기 현가장치(200)의 작동과정에서 걸이봉(40)의 하단에 결합되어진 밀착판(90)의 승.하강작동에 의해 하우징(60)내에 수용되어진 탄성스프링(70)이 압축되게 된다.On the other hand, the damping force of the suspension device 200 is variable by changing the size of the space portion 120 formed in the cover 110 through the cover plate 130, for example, the handle 160 exposed to the outside By moving the position along the cutout 150 through the medium to completely close or partially open the space 120 formed in the cover 110, the hook rod in the operation of the suspension device (200) The elastic spring 70 accommodated in the housing 60 is compressed by the lifting and lowering operation of the contact plate 90 coupled to the lower end of the 40.
이때 상기 하우징(60)내의 공기가 압축되면서 그 일부가 밀착판(90)과 하우징(60)의 내주면간격을 통하여 배출되게 되는데, 이 상태에서 상기와 같이 하우징(60)의 하부에 결합되어진 커버(110)를 덮개판(130)을 통하여 밀폐시키게 되면 상기 하우징(60)을 빠져나온 압축되어진 공기가 외부로 배출되지 못함으로서 현가장치(200)의 댐핑력이 상승하게 되는 것이다.At this time, as the air in the housing 60 is compressed, a part of the air is discharged through the inner circumferential surface interval of the contact plate 90 and the housing 60. In this state, the cover coupled to the lower portion of the housing 60 as described above ( When the 110 is sealed through the cover plate 130, the damping force of the suspension device 200 is increased by not allowing the compressed air that has exited the housing 60 to be discharged to the outside.
이와같이 커버(110)에 형성되어진 공간부(120)를 덮개판(130)을 통하여 밀폐시키거나 혹은 일부만 개장시키게 되면, 현가장치(200)의 댐핑력이 상승하게 되는 것이며, 그 반대로 상기 공간부(120)를 완전히 개방시키거나 그 일부만 밀폐되도록 덮개판(130)을 조절시키면 그만큼 현가장치(200)의 댐핑력이 낮아지게 됨으로서, 세탁기의 조립공정시 세탁기의 용량에 맞게 현가장치의 댐핑력을 간편하게 조절시킬수가 있게 되는 것이며, 또한 세탁기에 적용되어지는 부품이 비대칭으로 결합됨으로 인하여 발생되는 세탁기의 불균형을 바로 잡아주어 현가장치(200)의 진동감쇄효율을 극대화 시킬수가 있는 것이다.When the space 120 formed in the cover 110 is sealed or partially refurbished through the cover plate 130, the damping force of the suspension device 200 is increased, and vice versa. If the cover plate 130 is adjusted to fully open or partially seal the 120, the damping force of the suspension device 200 is lowered accordingly, so that the damping force of the suspension device can be easily adjusted according to the capacity of the washing machine during the assembly process of the washing machine. It will be able to adjust, and also to correct the imbalance of the washing machine caused by the asymmetrical combination of the components applied to the washing machine will be able to maximize the vibration damping efficiency of the suspension device (200).
본 고안은 세탁기의 외체와 저수조사이에 현가장치를 각각 장착시키되, 상기 현가장치에 적용되어지는 하우징은 그 하부에 덮개판의 결합위치에 따라 현가장치의 댐핑력을 세탁기의 용량 및 무게중심에 맞게 조절할수 있도록 하는 커버가 부착됨으로서, 조립시에 현가장치의 댐핑력을 세탁기의 용량에 맞게 간편하게 조절시킬수 있어 모든 세탁기에 범용적으로 적용시킬수 있게 되고, 또한 세탁기에 장착되어진 부품이 비대칭으로 장착됨으로 인하여 발생되는 현가장치의 편하중을 균형적으로 잡아 주게 됨으로서 세탁기의 저수조가 어느 한쪽으로 기울어지지 않게되어 현가장치의 진동흡수 효율을 극대화시킬수 있는 효과가 있는 것이다.The present invention is equipped with a suspension device on the outer body of the washing machine and the low water irradiator, the housing applied to the suspension device according to the coupling position of the cover plate in the lower portion of the housing according to the capacity and center of gravity of the washing machine By attaching a cover to adjust, the damping force of the suspension device can be easily adjusted to the capacity of the washing machine at the time of assembly, so that it can be universally applied to all washing machines, and also because the components mounted on the washing machine are mounted asymmetrically By balancing the generated load of the suspension is balanced so that the reservoir of the washing machine is not inclined to either side, thereby maximizing the vibration absorption efficiency of the suspension.
