While the damper 6 is provided to absorb the vibration of the water tank 2 in the up, down, left and right directions during washing and dehydration, the damper 6 has a round bar shape as shown in FIG. A support bracket 8 is fitted to an upper end portion of the bar 7 so that the support bracket 8 is inserted into the groove 5a formed at each corner of the upper plate 5 to be mounted thereon, and a spring cap 9 'is provided at the bottom of the bar 7. And the coil spring 10 is sequentially inserted therein, and then a rubber base 11 is attached to the lower end of the bar 7. In the state fitted to the fitting portion (2a) formed on the outer lower end of the spring cap (9 ') a water tank (2) is in the installed structure.
따라서, 상기와 같은 구조로 설치된 댐퍼(6)는 세탁조(3)내에 세탁물과 물이 채워진 다음, 수조(2)내의 세탁조(3)가 모터(4)에 의해 정/역 방향으로 불규칙적인 속도로 회전함에 따라 발생되는 수조(2)의 상하 및 좌우방향 진동을 상기 댐퍼(6)내에 장착된 코일스프링(10)의 복원력과 스프링캡(9')과 베이스부(11)사이의 마찰 및 스프링캡(9')내 공기의 압축특성에 의해 흡수되었다.Therefore, the damper 6 installed in the above structure is filled with the laundry and water in the washing tank 3, and then the washing tank 3 in the water tank 2 at an irregular speed in the forward / reverse direction by the motor 4. The vibration of the coil spring 10 mounted in the damper 6 and the friction between the spring cap 9 'and the base portion 11 and the vertical and horizontal vibrations of the water tank 2 generated by the rotation are generated. It was absorbed by the compression characteristics of the air in (9 ').

본 고안의 댐퍼(6)는 환봉형상으로 된 바아(7)의 상부선단에 지지브라켓트(8)가 끼워져 고정되고, 이 바아(7)의 하부에 종래보다 짧은 길이로 된 스프링캡(9)이 끼워지며, 이 스프링캡(9)의 내부에 코일스프링(10)이 상기 바아(7)를 둘러쌓도록 내설되면서 일부는 스프링캡(9)외부로 돌출된 상태로 되어 있는 한편, 상기 바아(7)의 하부선단에는 코일스프링(10)을 지지하도록 된 베이스부(11)가 부착되어 있는 바, 상기 스프링캡(9)의 상부선단내측에는 바아(7)와 스프링캡(9)의 틈새에 부합되도록 고리형상의 유연한 재질로 된 스페이서(12)가 끼워지고, 이 스페이서(12)의 이탈을 방지하도록 스프링캡(9)의 상부선단과 바아(7)사이에 록커(13)가 끼워져 스프링캡(9)과 압착에 의해 고정된 구조로 되어 있다.In the damper 6 of the present invention, the support bracket 8 is fitted to the upper end of the bar 7 having a round bar shape, and a spring cap 9 having a shorter length than the conventional one is provided at the bottom of the bar 7. While the coil spring 10 is installed inside the spring cap 9 so as to surround the bar 7, a part of the spring cap 9 protrudes out of the spring cap 9, while the bar 7 The base portion 11 is attached to the lower end of the bar to support the coil spring 10, the inner side of the upper end of the spring cap (9) to match the gap between the bar (7) and the spring cap (9) The spacer 12 made of an annular flexible material is inserted, and the locker 13 is inserted between the upper end of the spring cap 9 and the bar 7 so as to prevent the spacer 12 from being separated. 9) and the structure fixed by crimping.
따라서, 상기와 같은 구조로 이루어진 댐퍼(6)의 지지브라켓트(8)와 스프링캡(9)이 세탁기내의 상판(5)의 각 모서리부위에 형성된 요홈(5a)과 수조(2)의 하측부에 형성된 끼움부(2a)사이에 각각 장착되어 설치되게 되면, 세탁 및 탈수시에 세탁조(3)가 불규칙적인 속도로 정/역회전되어 수조(2)를 통해 이에 고정된 스프링캡(9)을 매개로 바아(7)로 전달되는 상하진동을 댐퍼(6)내에 설치된 코일스프링(10)에 의해 흡수되고, 좌우진동을 바아(7)와 스프링캡(9)사이에 내설된 스페이서(12)에 의해 효과적으로 흡수억제시킬 수 있게 될 뿐만 아니라, 상기 스프링캡(9)의 길이가 종래보다 짧게 형성되기 때문에 어넬링에 의한 열변형도 줄일 수 있게 되므로 제작불량률도 줄일 수 있게 된다.Therefore, the support bracket 8 and the spring cap 9 of the damper 6 having the above structure are formed at the lower portions of the grooves 5a and the water tank 2 formed at each corner of the upper plate 5 in the washing machine. When installed between the formed fitting portion (2a), respectively, when the washing and dehydration washing tank 3 is rotated forward / reverse at an irregular speed through the spring tank (9) fixed to it through the water tank (2) The vertical vibration transmitted to the furnace bar 7 is absorbed by the coil spring 10 installed in the damper 6, and the left and right vibrations are absorbed by the spacer 12 built in between the bar 7 and the spring cap 9. In addition to being able to effectively suppress the absorption, since the length of the spring cap 9 is formed to be shorter than the conventional thermal strain due to the annealing can also be reduced, thereby reducing the manufacturing defect rate.
이상 설명한 바와 같이 본 고안 세탁기용 진동흡수장치에 의하면, 세탁기내에 상판(5)과 수조(2)의 하부측면사이에 설치된 댐퍼(6)에 진동을 저감시켜 완충역할을 하도록 된 스페이서(12)가 삽입됨에 다라, 세탁조(3)의 정/역회전에 따른 세탁기의 진동이 흡수되는 잇점이 있게 된다.As described above, according to the vibration absorbing device for a washing machine of the present invention, the spacer 12 is configured to reduce vibration and dampen the damper 6 provided between the upper plate 5 and the lower side surface of the water tank 2 in the washing machine. As it is inserted, there is an advantage that the vibration of the washing machine due to the forward / reverse rotation of the washing tank (3) is absorbed.
