상기 완충봉재(1)가 관통되는 작동공(31)이 형성되며, 그 하부에 돌출 형성되는 보스부(32)가 구비된 하측완충구(3)와;An actuating hole 31 through which the buffer rod material 1 penetrates, and a lower cushioning tool having a boss portion 32 protruding from the lower portion thereof;

상기 하측고정부(12)에 의해 분리 방지되도록 삽입 설치되는 지지판(6)과;A support plate 6 inserted and installed to prevent separation by the lower fixing part 12;

상기 지지판(6)과 하측완충구(3)의 사이에 결합 설치되어 세탁외조(T)로 부터 전달된 진동 및 충격에 의해 압축과 이완운동을 하며 진동 및 충격을 완충시키는 탄성부재(4)와;An elastic member (4) coupled and installed between the support plate (6) and the lower buffer (3) to compress and relax by vibration and shock transmitted from the outer tub (T) and to cushion the vibration and impact. ;

상기 탄성부재(4)의 외주연부에 결합되어 압축과 이완운동시 탄성부재(4)의 외주면에 마찰력을 부여하는 완충관(5)으로 구성됨은 종래와 동일하다.The buffer member 5 is coupled to the outer periphery of the elastic member 4 to impart a frictional force to the outer peripheral surface of the elastic member 4 during compression and relaxation motion.

본 발명은 상기 하측완충구(3)의 보스부(32)에 진동으로 인하여 위치이탈된 탄성부재(4)를 다시 재 위치로 결합시키는 안내경사면(33)으로 구성됨에 그 특징이 있다.The present invention is characterized in that it consists of a guide inclined surface (33) for coupling the elastic member (4), which is displaced due to vibration in the boss portion 32 of the lower buffer (3) back to the position.

상기의 구성에 따른 작용효과를 설명하면 먼저, 전자동세탁기의 운전시 모우터에 의해 세탁내조(I)가 회전을 하며 세탁외조(T)로 전달되는 진동은 하측걸이부(T1)를 통해 하측완충구(3)로 전달되고, 상기 하측완충구(3)로 전달된 진동은 탄성부재(4)로 전달되어 탄성부재(4)의 압축 또는 이완작용에 의해 진동을 완충시키게 되며, 또한 상기 탄성부재(4)에서 완충되지 못한 여진동은 지지판(6)을 통하여 하측고정부(12)와 완충봉재(1)로 전달되고, 아울러 완충봉재(1) 상측의 상측완충구(2)와 본체(M)의 상측걸이부(M1)로 전달되면서 소진되어지며, 또한 상기 탄성부재(4)의 외주연부에 결합된 완충관(5)은 탄성부재(4)가 압축, 이완될 때 탄성부재(4)에 마찰력을 가해 완충효과를 더욱 증진시키게 된다.Referring to the operation effect according to the above configuration, first, the washing inner tank (I) is rotated by the motor during operation of the automatic washing machine and the vibration transmitted to the washing outer tank (T) is lowered through the lower hook portion (T1) The vibration transmitted to the sphere 3 and the lower shock absorber 3 is transmitted to the elastic member 4 to cushion the vibration by the compression or relaxation of the elastic member 4, and also the elastic member The vibration damping that is not buffered in (4) is transmitted to the lower fixing part 12 and the buffer rod 1 through the support plate 6, and the upper shock absorber 2 and the main body M on the upper side of the shock absorbing rod 1. It is exhausted while being transferred to the upper hook portion M1 of the), and the buffer tube 5 coupled to the outer periphery of the elastic member 4 has an elastic member 4 when the elastic member 4 is compressed and relaxed. The frictional force is applied to further enhance the cushioning effect.

한편, 상기 세탁내조(I)의 세탁물들이 서로 엉키어서 한쪽으로 치우쳐 회전을 하게 되면 상기 세탁내조(I) 및 세탁외조(T)의 상, 하 진동폭이 상승됨으로 인하여 댐퍼(D)의 진동폭도 상승하게 되며, 이때 종래에는 상기 탄성부재(4)의 일측부가 휘어지며 하측완충구(3)의 보스부(32) 하부에 걸리게 되는 경우가 발생하게 되고, 상기 탄성부재(4)의 일측부가 보스부(32)에 걸리게 되면 세탁내조(I) 및 세탁외조(T)의 균형을 잡아주는 댐퍼(D)가 기울어져 있게 됨으로 인하여 세탁내조(I)가 편심회전하여 진동 및 소음이 많이 발생하게 되는 문제점이 있었으나, 본 발명은 하측완충구(3)의 보스부(32)에 형성된 안내경사리브(33)에 의해 탄성부재(4)의 일측부가 보스부(32)의 하부에 걸리는 것이 방지되게 된다.On the other hand, when the laundry of the washing tank (I) is tangled with each other and rotated to one side, the vibration width of the damper (D) also increases because the vibration width of the washing inner tank (I) and the washing outer tank (T) is increased. In this case, in the related art, one side of the elastic member 4 is bent, and a case is caught by the lower portion of the boss part 32 of the lower cushion 3, and one side of the elastic member 4 is a boss. (32) when the damper (D) for balancing the washing tank (I) and the washing tank (T) is inclined, so that the washing tank (I) rotates eccentrically, causing a lot of vibration and noise However, in the present invention, one side of the elastic member 4 is prevented from being caught by the lower portion of the boss portion 32 by the guide inclined ribs 33 formed on the boss portion 32 of the lower shock absorber 3.

즉, 상기 세탁내조(I)가 편심회전을 하여 세탁내조(I) 및 세탁외조(T)의 상, 하 진동폭이 상승되면 댐퍼(D)의 상, 하 진동폭도 상승하며 세탁외조(T)로 부터 전달받은 진동을 감쇄시키나, 일정폭 이상으로 진동하게 되면 탄성부재(4)의 일측부가 휘어지며 하측완충구(3)의 보스부(32)에 걸리게 되지만, 상기 보스부(32)의 하부에는 안내경사리브(33)이 형성되어 있으므로, 상기 휘어지며 보스부(32)에 걸리려던 탄성부재(4)의 일측부는 안내경사리브(33)의 안내를 받으며 다시 원위치되어 댐퍼(D)가 재 역할을 할 수 있도록 위치하게 된다.That is, when the washing inner tank (I) rotates eccentrically and the upper and lower vibration widths of the washing inner tank (I) and the washing outer tank (T) are increased, the upper and lower vibration widths of the damper (D) also increase and the washing outer tank (T) When the vibration received from the attenuated, but vibrating more than a predetermined width, one side portion of the elastic member 4 is bent and caught by the boss portion 32 of the lower buffer 3, but the lower portion of the boss portion 32 Since the guide inclined rib 33 is formed, one side of the elastic member 4 which is bent and caught by the boss portion 32 is guided by the guide inclined rib 33 and is repositioned again so that the damper D serves again. To be located.

따라서, 상기 세탁내조(I) 내부의 세탁물들이 서로 엉키어서 세탁내조(I)가 편심회전하게 되어도 세탁외조(T)를 지지하는 댐퍼(D)가 세탁내조(I)에서 발생되어 세탁외조(T)로 전달된 진동을 감쇄시킴으로서 편심회전에 의한 진동이나 소음을 방지하는 한편, 사용자가 전자동세탁기를 편안하고 쾌적하게 사용할 수 있도록 하게 된다.Therefore, even when the laundry inside the washing tank (I) is tangled with each other and the washing washing tank (I) is eccentrically rotated, a damper (D) for supporting the washing outer tank (T) is generated in the washing washing tank (I) to wash the washing tank (T). By attenuating the vibration transmitted to) to prevent vibration or noise caused by eccentric rotation, the user can use the fully automatic washing machine comfortably and comfortably.

이와같이 된 본 발명은 하측완충구의 보스부 하부에 안내경사리브를 형성함으로서, 세탁물들이 한쪽으로 치우쳐 세탁내조가 편심회전할 때 댐퍼의 탄성부재가 위치이탈되며 하측완충구의 보스부 하단에 걸리게 되어도 상기 보스부의 하부에 형성된 안내경사리브의 안내를 받으며 탄성부재가 제 위치로 다시 돌아가 설치될 수 있도록 함으로서, 세탁내조의 편심회전에 의해 세탁내조 및 세탁외조의 상, 하 진동폭의 상승시에도 댐퍼가 진동을 감쇄하며 세탁내조 및 세탁외조의 균형을 잡아줌으로 인하여 진동이나 소음이 발생되는 것을 방지하도록 하는 유용한 효과를 갖는다.The present invention thus formed by forming a guide inclined rib in the lower portion of the boss of the lower cushion, the laundry is biased to one side, when the washing tank is eccentric rotation, the elastic member of the damper is dislocated and the boss even if caught on the bottom of the boss of the lower buffer The damper attenuates the vibration even when the upper and lower vibration widths of the washing inner tub and the outer tub are increased by the eccentric rotation of the inner tub of the laundry by being guided by the guide inclined rib formed at the lower part of the section. And it has a useful effect to prevent the occurrence of vibration or noise due to the balance between the washing tank and the laundry tank.
