본 발명은 세탁기의 진동감쇠 댐퍼어셈블리에 관한 것으로서, 더욱 상세하게는 상하측 1조식 발란서가 구비된 세탁기에 있어 탈수초기 과도진동을 억제할 수 있는 진동감쇠 댐퍼어셈블리에 관한 것이다.The present invention relates to a vibration damper assembly of a washing machine, and more particularly, to a vibration damper assembly which can suppress the initial vibration of the dehydration in the washing machine provided with a pair of upper and lower side balance.
일반적으로 세탁기는, 제1도 및 제2도의 (a)에 도시된 바와 같이, 세탁물을 담는 탈수조(3)와, 탈수조를 감싸는 세탁조(4)와, 이 세탁조 하부에 설치되어 세탁수류를 발생시키는 회전익(6)과, 세탁조의 외곽에 설치되어 세탁조의 진동을 잡아주는 댐퍼어셈블리(50) 및 탈수조의 진동을 완화시키는 발란서(1)(2)를 포함하고 있다.Generally, a washing machine includes a dehydration tank 3 containing laundry, a washing tank 4 surrounding a dehydration tank, and a washing water flow installed at a lower portion of the washing tank, as shown in FIGS. 1 and 2 (a). A rotary blade 6 to be generated, a damper assembly 50 installed outside the washing tank to hold the vibration of the washing tank and a balancer 1 and 2 for alleviating the vibration of the dewatering tank are included.
한편, 세탁물로부터 때를 충분히 뺀 다음에는 탈수조를 고속회전시켜 탈수하게 된다.On the other hand, after sufficiently removing the time from the laundry, the dewatering tank is rotated at high speed to dewater.
보편적인 탈수원리는 탈수조(3)의 고속회전시 형성되는 상당한 세기의 원심력으로 인해 세탁물로부터 물기가 완전히 빠져나가는 것이다.A common dehydration principle is the complete drainage of laundry from the laundry due to the centrifugal force of considerable strength formed during the high speed rotation of the dehydration tank (3).
상기 탈수조(3)의 고속회전 중 자연히 진동이 발생하게 되며, 이를 해결하기 위해 탈수조의 상측 또는 상하측에 발란서(1)(2)를 착설하는 한편, 세탁조 외곽에 댐퍼어셈블리(50)를 별도로 부설한다.Vibration naturally occurs during the high speed rotation of the dehydration tank (3), and in order to solve this problem, the balancer (1) (2) is installed on the upper or upper and lower sides of the dehydration tank, and the damper assembly (50) is disposed outside the washing tank. Install separately.
여기서, 댐퍼어셈블리(50)는 세탁기 외측상단의 브라켓(7)에 관통되어 결착된 지지대(51)와, 세탁조 외주면에 부착된 댐퍼부재(53)와, 이 댐퍼부재와 지지대 사이에 개재된 스프링(52)을 포함하여 세탁조의 진동을 흡수한다.Here, the damper assembly 50 includes a support 51 penetrated through the bracket 7 of the upper upper end of the washing machine, a damper member 53 attached to the outer circumferential surface of the washing tank, and a spring interposed between the damper member and the support. 52) to absorb the vibration of the washing tank.
한편, 탈수조의 발란서는 일정 무게를 가진 것으로서, 상측 발란서와 상하측 1조식 발란서의 2가지 유형이 있다.On the other hand, the balance of the dehydration tank is of a certain weight, there are two types of upper balancer and upper and lower one tank balancer.
상측발란서(1)하나만 부착된 세탁기의 경우, 탈수조(3)가 회전함에 따라 제1도(b)에 도시된 바와 같은 진동모드가 발생한다. 즉, 탈수조의 고속회전시 그 상측에 발란서가 부착되어 있어서, 탈수조 상단부를 일종을 정점으로 하는 원추진자와 같은 회전운동이 이루어진다. 이러한 구조에서는, 탈수중 세탁물의 쏠림등으로 인하여 탈수조(3)에 충격적인 이상수평력이 작용하게 되더라도 그 힘은 댐퍼부재(53) 및 스프링(52)에 의해 상쇄되어 소멸한다. 물론, 원추진자운동이 지닌 특성으로 인해 외관상의 불안정감 및 관련지지부의 변형등 본질적 문제 자체가 해결되는 건 아니다.In the case of a washing machine having only one upper balancer 1 attached thereto, a vibration mode as shown in FIG. 1 (b) occurs as the dehydration tank 3 rotates. That is, the balancer is attached to the upper side during the high speed rotation of the dehydration tank, so that a rotational motion such as a conical pendulum having the upper end of the dehydration tank as a peak is made. In such a structure, even if a shocking abnormal horizontal force acts on the dewatering tank 3 due to the deflection of laundry during dewatering, the force is canceled by the damper member 53 and the spring 52 and disappears. Of course, the nature of the cone motion does not solve the inherent problems of the instability and deformation of the associated support itself.
아울러, 상측발란서(1)와 하측발란서(2)가 병설된 경우, 탈수조의 진동모드는 제2도(b)에 도시된 바와 같다. 즉, 탈수조의 상하 양단부가 동일한 변위를 지닌채로 원통형상의 회전운동을 하게 된다. 이 경우, 앞서의 원추진자운동에서와 같은 관련 지지부의 변형부하는 완화되는 경향이 있다.In addition, when the upper balancer (1) and the lower balancer (2) are installed in parallel, the vibration mode of the dehydration tank is as shown in Figure 2 (b). That is, the upper and lower ends of the dehydration tank has a cylindrical rotational movement with the same displacement. In this case, the deformation load of the associated support as in the previous cone motion tends to be relaxed.
그러나, 앞서 언급한 이상수평력이 탈수조(3)에 작용하는 경우에는, 상기 상측발란서(1)의 경우에서와 같은 탈수조 하단부만의 이동이 아니라, 탈수조(3) 전체가 일측으로 쏠리는 형태의 부하를 받는다. 즉, 댐퍼부재(53) 및 지지대(51)를 포함한 댐퍼어셈블리(50)가 그 전체로서 외측 또는 내측으로 쏠리게 된다. 이처럼, 이상 수평력으로 인한 부하력이 댐퍼부재(53) 및 지지대(51)의 길이방향으로 제대로 작용하지 않기 때문에 상기 2개의 완충부재는 제기능을 전혀할 수 없게 된다.However, when the above-described abnormal horizontal force acts on the dehydration tank 3, the entire dehydration tank 3 is directed to one side, not the movement of only the lower end of the dehydration tank as in the case of the upper balancer 1. Under load. That is, the damper assembly 50 including the damper member 53 and the support 51 is pulled outward or inward as a whole. As such, the two buffer members cannot function at all because the load force due to the abnormal horizontal force does not work properly in the longitudinal direction of the damper member 53 and the support 51.
결과적으로, 탈수조(3)에 가해진 이상수평력은 댐퍼어셈블리(50)상단이 연결된 브라켓부에 집중적으로 작용하게 되어 관련부의 손상 및 불안감을 느낄 정도의 심한 진동이 발생한다.As a result, the abnormal horizontal force applied to the dehydration tank (3) is concentrated on the bracket portion connected to the upper end of the damper assembly 50, so that severe vibration occurs to feel the damage and anxiety of the associated portion.
본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로서, 상하측 발란서(1)(2)가 구비된 세탁기에 있어서, 탈수초기 과도진동을 효율적으로 억제할 수 있는 진동감쇠 댐퍼어셈블리를 제공함을 목적으로 한다.The present invention has been made in view of the above-described conventional problems, in the washing machine provided with the upper and lower balancer (1) (2), to provide a vibration damping damper assembly that can effectively suppress the initial vibration of dehydration. For the purpose.
이러한 본 발명의 목적은 통상 댐퍼어셈블리의 상단부에 보조지지대를 부설함으로써 달성된다.This object of the present invention is usually achieved by placing an auxiliary support on the upper end of the damper assembly.
즉, 상기 브라켓에 지지대 상단과 간격을 두고 상단이 결착되고 하단은 상기 지지대와 결합된 보조지지대를 설치하여 세탁조 전체의 일방향 쏠림을 잡아줄 수 있도록 하는 것을 특징으로 한다.That is, the upper end is bound to the bracket at an interval with the upper end and the lower end is characterized in that the auxiliary support coupled to the support to hold the one-way pull of the entire washing tank.
이러한 본 발명의 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings an embodiment of the present invention.
본 발명의 실시예는, 제3도에 도시된 바와 같이, 지지대(51)와 스프링(52) 및 댐퍼부재(53)를 포함하는 댐퍼어셈블리(50)의 상단부에 별도의 보조지지대(54)를 착설한다.According to the embodiment of the present invention, as shown in FIG. 3, a separate auxiliary support 54 is provided at the upper end of the damper assembly 50 including the support 51, the spring 52, and the damper member 53. Install it.
즉, 상기 지지대(51)의 상부에 일단이 고정되고 세탁기 외측상단에 설치된 브라켓(7)에 타단이 고정되는 보조지지대(54)를 부설하여, 지지대(51)에 작용하는 탈수조 전체의 일방향 쏠림을 잡아줄 수 있다.That is, an auxiliary support 54 having one end fixed to the upper portion of the support 51 and the other end fixed to the bracket 7 installed on the upper side of the washing machine is laid, and the one-way pull of the entire dehydration tank acting on the support 51. Can hold.
상기 보조지지대(54)는 완충성능이 좋은 고무 또는 합성수지재로서 상기 브라켓(7)위로 돌출된 상단부가 원판형(54a)으로 형성되고, 동일폭의 몸체로 형성된 중앙부(54b)와, 지지대(51)가 삽입 관통되는 홀더구멍(54d)이 구비된 하단부(54c)로 구성된다.The auxiliary support 54 is a rubber or synthetic resin having a good buffering performance, the upper end protruding onto the bracket (7) is formed in a disk shape (54a), the central portion (54b) and the support (51) formed of the same width body Is a lower end portion 54c provided with a holder hole 54d through which is inserted.
한편, 보조지지대(54) 하단부(54c)의 홀더구멍(54d)에는 강성체로 된 보강부재가 접착됨으로써, 연질 고무재의 하단부(54c)가 지지대(51)와 직접 마찰함으로 인한 손상을 방지토록 한다. 또한, 보조지지대(54)는 브라켓(7) 일측의 보조지지대의 몸체 폭 정도의 홈에 끼워짐으로써 그 상단부의 원판형(54a)이 브라켓(7)에 걸려 빠지지 않도록 고정한다.On the other hand, the reinforcing member made of rigid material is bonded to the holder hole 54d of the lower end 54c of the auxiliary support 54 so that the lower end 54c of the soft rubber material is directly rubbed with the support 51 to prevent damage. In addition, the auxiliary support 54 is inserted into a groove about the width of the body of the auxiliary support on one side of the bracket (7) to fix the disk-shaped 54a of the upper end so as not to be caught in the bracket (7).
이상 설명한 바와 같이, 본 발명 세탁기 진동감쇠 댐퍼어셈블리는 통상 댐퍼어셈블리의 상단부에 보조지지대를 부설하여 세탁조 전체의 일방향 쏠림을 잡아줌으로써 탈수초기의 과도진동을 억제할 수 있는 효과가 있다.As described above, the washing machine vibration damper assembly of the present invention generally has an effect of suppressing excessive vibration of the dehydrator by placing an auxiliary support on the upper end of the damper assembly to catch one-way pull of the entire washing tank.
