A control unit (not shown) for washing by selectively operating a corresponding button by a user is mounted at a predetermined position of the upper cover 6, and the washing water required for washing in the washing machine body 1 is stored at a predetermined level. The washing tank 2 is mounted, and the washing tank 2 described above is damper of several suspension bars 7 having one end fixed to an upper side inside the washing machine body 1 and the other end fixed to a lower side of the outer periphery of the washing tank 2. 8) is mounted to attenuate the vibration and noise generated during the dehydration administration, the dehydration tank (4) into which the laundry is introduced into the washing tank (2) is rotatably mounted by the drive unit (3), dehydration tank ( 4) is stopped during the laundry administration, Performing time there is mounted so as to perform a dehydration stroke with the rotary blades 5 and the one-way repeatedly rotatable crane equipped with a forward and reverse direction inside.

위와같이 구성되는 자동세탁기의 세탁, 헹금, 배수행정이 완료되고 탈수행정이 시작되는 경우, 탈수조(4) 및 회전날개(5) 회전으로 세탁조(2)로부터 세탁수가 배출되며, 이와 동시에 세탁물의 중량이 줄어들게 됨에 따라 댐퍼(8)의 스프링(8A)은 압축상태에서 복원된다. 이로인해 승하강하는 댐퍼(8)의 시일(8B)에 의해 탈수행정시 세탁물의 편심으로 인한 세탁조의 언바란스에 따라 발생되는 진동 및 소음이 감쇄된다.When the washing, rinsing, and draining stroke of the automatic washing machine configured as described above is completed and the dehydration stroke is started, the washing water is discharged from the washing tank 2 by the rotation of the dehydration tank 4 and the rotary blades 5, and at the same time As the weight is reduced, the spring 8A of the damper 8 is restored in the compressed state. As a result, the seal 8B of the damper 8 which moves up and down is attenuated by vibration and noise generated by unbalance of the washing tank due to the eccentricity of the laundry during dehydration administration.

그러나, 전술한 세탁조(2)의 진동을 감쇄시키는 댐퍼(8)는 탈수조(4) 및 세탁조(2)에 세탁물 및 세탁수가 전혀없는 상태 즉, 무부하상태에서의 세탁조(2)의 무게중심에 따라 스프링(8A)의 탄성계수가 설정된 것이다.However, the damper 8 for damping the vibration of the washing tank 2 described above is located in the dehydration tank 4 and the washing tank 2 at the center of the weight of the washing tank 2 in a state where no laundry and no washing water exist at all.

도면에 도시된 바와같이, 세탁기본체(1)상부에 장착되어 세탁, 헹굼, 배수 및 탈수행정을 미리 마이콤에 의해 프로그램화 시켜두어 사용자에 의해 해당버튼을 선택적으로 조작하여 세탁하게 되는 콘트롤부와, 세탁기본체(1) 내부에 장착되어 세탁수를 일정 레벨로서 저수하며, 탈수행정시 발생되는 진동을 감쇄시키도록 댐퍼(8)가 장착되는 세탁조(2)와, 세탁조(2) 내부에 회전가능하게 장착되어 세탁행정중에는 정지하며, 탈수행정시에는 내부에 정, 역방향으로 반복적으로 회전가능하게 장착되는 회전날개(5)와 일방향으로 회전하는 탈수조(4)에 대한 구성은, 제1도에 도시된 종래의 구성과 동일하므로 이에 대한 구성 및 작동의 상세한 설명은 생략하며, 인용부호를 동일하게 표기하였다.As shown in the figure, the control unit is mounted on the washing machine body (1) and the washing, rinsing, drainage and dehydration stroke is programmed by the microcomputer in advance by the user to selectively operate the corresponding button to wash; Washing tank (2) mounted inside the washing machine body (1) to store the wash water at a certain level, and equipped with a damper (8) so as to attenuate the vibration generated during dehydration administration, and rotatably inside the washing tank (2) The configuration of the rotary blade 5 and the dewatering tank 4 that rotates in one direction are mounted and stopped during the washing stroke, and rotated in the forward and reverse directions repeatedly during the dehydration stroke, as shown in FIG. Since the same as the conventional configuration, detailed description of the configuration and operation thereof will be omitted, and the same reference numerals.

따라서, 본 고안의 바람직한 실시예의 의하면, 전술한 세탁조(2) 저면에 평판형의 슬라이더(10)가 일체형으로 대향되게 장착되며, 슬라이더(10)와 마찰접촉되며 세탁조(2) 승하강을 유도하여 세탁조(2)의 상하 방향운동에 따른 진동을 감소시키는 제1 마찰부재(11)의 내부 소정 위치에 반구 형상의 마찰편(12)이 일체로 형성된다.Therefore, according to a preferred embodiment of the present invention, the flat slider 10 is integrally mounted on the bottom surface of the washing tank 2 as described above, in friction contact with the slider 10 and induces the lowering and lowering of the washing tank 2. A hemispherical friction piece 12 is integrally formed at a predetermined position inside the first friction member 11 which reduces vibration caused by the vertical movement of the washing tub 2.

제1 마찰부재(11) 저면에 반구 형상의 마찰편(13)이 일체로 형성되며, 제1 마찰부재(11)와 세탁기본체(1)상에 고정된 받침대(1A)사이에 세탁조(2) 회동에 대응되게 제1 마찰부재(11)를 회동시키는 제 2 마찰부재(14)를 장착하되, 제 2 마찰부재(14)는 제1 마찰부재(11)와 대응되게 상면이 볼록하게 형성되며, 볼록한 상면이 제1 마찰부재(11)의 마찰편(13)과 마찰접속하며, 저면은 받침대(1A)상에 형성된 마찰편(15)상에 안착된다.The hemispherical friction piece 13 is integrally formed on the bottom surface of the first friction member 11, and the washing tank 2 is disposed between the first friction member 11 and the pedestal 1A fixed on the washing machine body 1. The second friction member 14 is mounted to rotate the first friction member 11 to correspond to the rotation. The second friction member 14 is formed to have a convex upper surface corresponding to the first friction member 11. The convex upper surface is frictionally connected to the friction piece 13 of the first friction member 11, and the bottom surface is seated on the friction piece 15 formed on the pedestal 1A.

전술한 받침대(1A)상에 안착되는 제 2 마찰부재(14)에 대해 제1 마찰부재(11)의 접촉된 초기상태를 탄성바이어스하는 탄성부재(16) 양단부가 제1 마찰부재(11)와 받침대(1A) 소정위치에 각각 고정된다.Both ends of the elastic member 16 elastically biases the initial state of contact of the first friction member 11 with respect to the second friction member 14 seated on the above-described pedestal 1A and the first friction member 11. Each pedestal 1A is fixed at a predetermined position.

위와같이 구성되는 본 고안에 의한 자동세탁기의 진동방지장치의 작동을 설명하면 세탁조(2)에 세탁수가 소정량으로 저수되며 탈수조(4)에 소정의 세탁물과 분말세제가 투입되어짐에 따라 세탁조(2)의 중량은 최대 되며, 이로인해 세탁조(2)에 장착된 댐퍼(8)의 스프링(8A)은 압축상태가 됨과 동시에 세탁조(2)는 스프링(8A)의 탄성력만큼 하강하게 된다. 이후, 상부커버(6) 소정위치에 장착되는 콘트롤부의 해당 조작버튼을 사용자가 선택함에 따라 세탁기는 세탁, 헹금, 배수, 탈수 행정을 미리 프로그램화된 순서에 따라 세탁행정을 수행하게 된다.Referring to the operation of the anti-vibration device of the automatic washing machine according to the present invention constituted as described above, the washing water is stored in the washing tank 2 in a predetermined amount, and the laundry and powder detergent are put into the dehydrating tank 4 so that the washing tank ( The weight of 2) is maximum, which causes the spring 8A of the damper 8 mounted on the washing tank 2 to be compressed and at the same time the washing tank 2 is lowered by the elastic force of the spring 8A. Thereafter, as the user selects a corresponding operation button of the control unit mounted at the predetermined position of the upper cover 6, the washing machine performs washing administration according to a pre-programmed order of washing, rinsing, draining and dehydrating stroke.

전술한 세탁행정중 구동부(3) 구동으로 탈수조(4) 및 탈수조(4) 내부에 장착되는 회전날개(5)의 회전으로 인한 탈수행정 초기에, 세탁조(2)로부터 세탁수가 배출됨에 따라 탈수조(4) 내부의 세탁물의 중량이 점진적으로 줄어들게 된다.As the washing water is discharged from the washing tank 2 at the initial stage of the dehydration stroke due to the rotation of the dehydration tank 4 and the rotary blade 5 mounted inside the dehydration tank 4 by driving the driving unit 3 during the washing operation. The weight of the laundry inside the dehydration tank 4 is gradually reduced.

이로인해 세탁조(2)에 장착된 댐퍼(8)의 스프링(8A)이 압축상태에서 복원됨에 따라 서스펜션바(7)에 의해 탈수시 세탁조(2)에 발생되는 진동은 흡수되어 1차적으로 감쇄되어진다.Due to this, as the spring 8A of the damper 8 mounted on the washing tank 2 is restored in the compressed state, the vibration generated in the washing tank 2 when the water is dehydrated by the suspension bar 7 is first attenuated. Lose.

그리고, 제3도의 (a)에 도시된 바와같이, 탈수시 세탁조(2)의 상하방향 운동에 따라 발생되는 진동은 세탁조(2) 저면에 일체로 장착된 대향하는 슬라이더(10)가 이를 수용하는 제1 마찰부재(11)의 마찰편(12)과 마찰접촉하면서 세탁조(2)의 승하강을 유도하게 되므로 감소되어진다.And, as shown in (a) of FIG. 3, the vibration generated by the vertical movement of the washing tub 2 during dehydration is received by the opposite slider 10 integrally mounted on the bottom of the washing tub 2. Since the frictional contact with the friction piece 12 of the first friction member 11 induces the lowering and lowering of the washing tub 2, it is reduced.

한편, 제3도의 (b)에 도시된 바와같이, 세탁조(2)가 탈수시 상하방향의 이동은 없는 상태에서 화살표시 방향으로 회동하는 경우, 세탁조(2)의 슬라이더(10)에 마찰접촉된 제1 마찰부재(11)가 세탁조(2) 회동방향에 대응되어 제 2 마찰부재(14)와 마찰접촉하면서 회동되므로, 세탁조(2)의 진자운동에 따른 진동은 감소되어진다.On the other hand, as shown in (b) of FIG. 3, when the washing tank 2 is rotated in the direction of the arrow when there is no movement in the up and down direction when dewatering, friction contact with the slider 10 of the washing tank 2 Since the first friction member 11 is rotated while being in frictional contact with the second friction member 14 in correspondence with the rotation direction of the washing tub 2, the vibration caused by the pendulum movement of the washing tub 2 is reduced.
