The upper cam 8 which raises and lowers the lower cam 6 when it rotates by forming the 2nd cam 7 in the lower part so that the cam 6 and the 1st cam 5 of the said lower cam 6 may engage. ), The rotary shaft 9 is coupled to the upper cam 8 by the coupling means and exposed to the outside and connected to the upper cover 51 of the washing machine. Consists of a front barrel (9) with a cover 10 to be securely fixed to the housing 2 so as to housed in a housing (2).

상기한 승강수단은 하우징(2)의 내측면에 하나 이상 형성된 수직홈(11)과, 상기한 수직홈(11)에 삽입되어 하부캠(6)이 승강 가능하면서 회전하지 않도록 하부캠(6)에 형성된 수직돌기(12)로 이루어져 있다.The elevating means is at least one vertical groove 11 formed on the inner surface of the housing 2 and the lower cam 6 is inserted into the vertical groove 11 so that the lower cam 6 can be lifted and not rotated. It consists of a vertical projection (12) formed in.

즉, 상기한 상부캠(8)에 의해 하부캠(6)이 밀리게 되면 하부캠(6)이 수직홈(11) 및 수직돌기(12)를 타고 승강 운동하도록 구성된 것이다.That is, when the lower cam 6 is pushed by the upper cam 8, the lower cam 6 is configured to move up and down on the vertical groove 11 and the vertical protrusion 12.

또한, 상기한 결합수단은 도 1과 도 3에 도시된 바와 같이 상부캠(8)의 상면 중심에 형성된 각형의 결합돌기(13)와, 상기한 결합돌기(13)와 결합되도록 회전축(9)의 저면에 형성된 결합홈(14)으로 이루어져 있는바, 상기한 결합돌기(13)와 결합홈(14)에 의해 동력이 전달되는 것이다.In addition, the coupling means, as shown in Figures 1 and 3, the rotating shaft (9) to be coupled to the engaging projection 13 of the square formed in the center of the upper surface of the upper cam (8), the engaging projection (13). Consists of a coupling groove 14 formed on the bottom of the bar, the power is transmitted by the coupling projection 13 and the coupling groove (14).

특히, 상부캠(8)에 형성된 하나 이상의 보조돌기(15)와, 상기한 보조돌기(15)가 끼워지도록 회전축(9)에 형성된 보조홈(16)이 형성되어 상부캠(8)과 회전축(9)의 결합력이 더욱더 견고해지고, 회전시 하중이 분산되어 동력 전달 효율이 향상되게 된다.In particular, one or more auxiliary protrusions 15 formed on the upper cam 8 and the auxiliary grooves 16 formed on the rotating shaft 9 so that the auxiliary protrusions 15 are fitted are formed to form the upper cam 8 and the rotating shaft ( The coupling force of 9) is more firm and the load is distributed during rotation, thereby improving the power transmission efficiency.

상기한 결합돌기(13) 및 결합홈(14)과, 보조돌기(15) 및 보조홈(16)에 의해 동력이 전달되면 회전축(9)과 상부캠(8)이 일체로 형성되었을 때에 비해, 하중이 분산되어 보다 큰 하중을 견딜 수 있게 된다.When power is transmitted by the coupling protrusion 13 and the coupling groove 14, the auxiliary protrusion 15 and the auxiliary groove 16, the rotary shaft 9 and the upper cam 8 are integrally formed, The load is distributed so that it can withstand greater loads.

즉, 회전축(9)과 상부캠(8)이 일체로 형성되어 있으면, 회전축(9)이 견딜 수 없을 정도의 하중이 인가되면 회전축(회전축과 상부캠의 연결부분)이 비틀어져 파손되지만, 본원에서는 큰 하중이 인가되어도 결합돌기(13) 및 결합홈(14)과, 보조돌기(15) 및 보조홈(16)에 하중이 분산되면서 회전축(9)의 파손을 방지할 수 있게 되는 것이다.That is, if the rotary shaft 9 and the upper cam 8 is integrally formed, when the load applied to the rotation shaft 9 is unbearable, the rotating shaft (connecting portion of the rotary shaft and the upper cam) is twisted and damaged, but in the present application Even when a large load is applied, the load is distributed to the coupling protrusion 13 and the coupling groove 14, the auxiliary protrusion 15, and the auxiliary groove 16, thereby preventing damage to the rotation shaft 9.

특히, 상기한 커버(10)와 회전축(9)의 사이에는 회전축(9)의 회전 시 마찰력을 감소시키기 위해, 윤활부재(17)가 설치되어 있는바, 상기한 윤활부재(17)에는 걸림돌기(18)가 형성되어 있고, 도 4에 도시된 바와 같이 상기한 걸림돌기(18)가 걸리도록 커버(10)의 저면에 걸림홈(19)이 형성되어 윤활부재(17)가 회전되는 것을 방지하게 된다.In particular, the lubrication member 17 is provided between the cover 10 and the rotation shaft 9 to reduce the frictional force when the rotation shaft 9 rotates, and the lubrication member 17 has a locking projection. 18 is formed, and as shown in FIG. 4, a locking groove 19 is formed on a bottom surface of the cover 10 so that the locking protrusion 18 is caught, thereby preventing the lubrication member 17 from rotating. Done.

상기한 윤활부재(17)는 테프론 등과 같이 마찰력이 작고 강도 및 내마모성이 우수한 재질을 사용하게 된다.The lubrication member 17 is made of a material having a low friction and excellent strength and wear resistance, such as Teflon.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 세탁기의 상부커버(51)를 열게 되면 상부커버(51)와 연결되어 있는 회전축(9)이 같이 회전하게 되고, 상기한 회전축(9)의 회전에 의해 상부캠(8)이 같이 회전하게 된다.Referring to the operation and effect of the present invention as described above, when the upper cover 51 of the washing machine is opened, the rotating shaft 9 connected to the upper cover 51 rotates together, and the rotation of the rotating shaft 9 is performed. The upper cam 8 is rotated together.

이때, 상기한 윤활부재(17)가 커버(10)와 회전축(9)의 사이에서 윤활 작용을 하게 됨으로써, 회전축(9)이 매우 부드럽게 회전하게 되고 마찰도 감소되기 때문에 소음도 감소하게 된다.At this time, the lubricating member 17 is lubricated between the cover 10 and the rotating shaft 9, so that the rotating shaft 9 rotates very smoothly and friction is also reduced, thereby reducing noise.

상부캠(8)이 회전축(9)에 의해 회전하게 되면 상부캠(8)의 하부에 형성된 제2캠(7)이 하부캠(6)의 상부에 형성된 제1캠(5)과 맞물려 회전하게 되고 이때 하부캠(6)은 아래로 눌리게 되고, 이로 인해 하부캠(6)이 하향 운동하게 된다.When the upper cam 8 is rotated by the rotary shaft 9, the second cam 7 formed at the lower portion of the upper cam 8 is engaged with the first cam 5 formed at the upper portion of the lower cam 6 to rotate. At this time, the lower cam 6 is pressed down, which causes the lower cam 6 to move downward.

하부캠(6)이 하향 운동하게 되면 제1, 2스프링(3, 4)이 눌리게 되고, 상기한 제1, 2스프링(3, 4)의 탄성에 의해 상부캠(8), 하부캠(6) 및 회전축(9)이 회전할 때 탄성력이 작용하여 세탁기의 상부커버(51)가 보다 천천히 회전하고 탄성적으로 작동하게 된다.When the lower cam 6 moves downward, the first and second springs 3 and 4 are pressed, and the upper cam 8 and the lower cam (by the elasticity of the first and second springs 3 and 4) are pressed. 6) and when the rotating shaft 9 rotates, the elastic force acts so that the upper cover 51 of the washing machine rotates more slowly and elastically operates.

여기서, 상기한 하부캠(6)은 하우징(2)에 형성된 수직홈(11)을 타고 승강 운동하게 되는바, 상부캠(8)을 따라 회전하지 않고 안정적으로 승강운동을 하면서 탄성을 회전축(9)에 인가하게 된다.Here, the lower cam 6 is to be moved up and down on the vertical groove (11) formed in the housing (2), without rotating along the upper cam (8) while stably lifting the elastic axis of rotation (9) ) Is applied.

이때, 상기한 회전축(9)에 매우 큰 하중인 인가되면 회전축(9)과 상부캠(8)에 형성된 결합돌기(13) 및 결합홈(14)과, 보조돌기(15) 및 보조홈(16)에 하중이 분산되어 큰 하중에도 견딜 수 있을 뿐 아니라 회전축(9) 등의 부품이 파손되지 않게 된다.At this time, when a very large load is applied to the rotary shaft 9, the coupling protrusion 13 and the coupling groove 14 formed on the rotary shaft 9 and the upper cam 8, the auxiliary protrusion 15, and the auxiliary groove 16. ), The load is distributed, so that it is not only able to withstand large loads but also parts such as the rotating shaft 9 are not damaged.
