본 고안에 따른 세탁기의 밸런서는 밸런서의 케이스에 판상의 억제부재를 설치함으로써 액체가 고유진동수 범위내에서 이동하는 것을 억제함으로써 회전 초기 밸런서에 의하여 언밸런서가 심화되는 것을 방지할 수 있는 이점이 있다.The balancer of the washing machine according to the present invention has an advantage that the unbalancer can be prevented from being deepened by the initial rotational balancer by preventing the liquid from moving in the natural frequency range by installing a plate-like suppressing member in the case of the balancer.
Description
본 고안은 회전조에 설치되어 편심에 의한 언밸런서를 감쇄하는 밸런서에 관한 것으로, 더 상세하게는 초기 유동을 억제하여 초기 과도진동을 억제할 수 있는 세탁기의 밸런서에 관한 것이다.The present invention relates to a balancer installed in the rotating tank to attenuate the unbalancer due to eccentricity, and more particularly, to a balancer of a washing machine capable of suppressing initial transient vibration by suppressing initial flow.
일반적으로 일조식 전자동 세탁기는 세탁물을 세탁하는 세탁행정과 세탁물의 물기를 탈수하는 탈수행정을 갖는다. 세탁행정은 회전날개의 정역회전에 의하여 형성된 수류에 의하여 수행되고, 탈수는 회전조의 고속회전에 의하여 물기가 세탁물에서 원심분리됨으로써 수행된다. 이와 같이 고속회전하여 탈수를 수행하는 회전조에는 세탁물의 편심 등에 의한 편심회전과 진동이 발생하는 것은 필연적이다. 이러한 편심회전이나 진동을 방지하기 위하여 회전조에는 도1에 도시한 바와 같은 밸런서가 장착되었다. 밸런서(2)는 회전조(1)의 상단에 환형의 홈(2a)을 형성하도록 설치된 케이스(2b)와 이 홈(2a)에 수용된 액체(2c)로 구성된다. 이와 같이 구성된 밸런서(2)는 회전조(1)의 회전시 도2의 "A","B","C'에 도시한 바와 같이 액체(2c)가 편심의 반대방향으로 이동함으로써 편심에 의한 언밸런서를 감쇄시킨다.In general, a solar powered automatic washing machine has a laundry administration for washing laundry and a dehydration stroke for dehydrating the laundry. Washing administration is performed by the water flow formed by the forward and reverse rotation of the rotary blade, dehydration is performed by centrifugation of the water in the laundry by the high-speed rotation of the rotary bath. As described above, it is inevitable that eccentric rotation and vibration occur due to the eccentricity of the laundry in the rotating tank that performs high speed rotation. In order to prevent such eccentric rotation and vibration, the rotating tank is equipped with a balancer as shown in FIG. The balancer 2 consists of the case 2b installed so that the upper end of the rotating tank 1 may form the annular groove 2a, and the liquid 2c accommodated in this groove 2a. The balancer 2 configured as described above is caused by the eccentricity by moving the liquid 2c in the opposite direction of the eccentricity as shown in Fig. 2A, B, and C when the rotary tub 1 is rotated. Attenuate the unbalancer.
그러나 이와 같은 액체를 이용한 밸런서는 회전조의 회전 초기에는 편심과 같은 방향으로 액체가 이동하다가 고유진동수 영역(도2의 "B")을 통과한 후에 편심의 반대방향으로 이동하기 때문에 고유진동수 영역 이전에는 회전조의 언밸런스를 증가시켜 진동을 심화시킨다.However, the balancer using such a liquid moves in the same direction as the eccentricity at the beginning of the rotation of the rotating tank and then moves in the opposite direction of the eccentricity after passing through the high frequency region ("B" in FIG. 2). Increasing the unbalance of the rotating tank intensifies vibration.
본 고안은 상기한 문제를 해결하기 위하여 고안된 것으로, 본 고안의 목적은 회전조의 회전초기 밸런서에 의하여 편심과 이에 의한 진동이 심화되는 것을 방지할 수 있는 세탁기의 밸런서를 제공하는 것이다.The present invention has been devised to solve the above problems, an object of the present invention is to provide a balancer of the washing machine that can prevent the eccentricity and the vibration caused by the rotary initial balancer of the rotating tub to be intensified.

이하에서는 첨부도면을 참조하여 본 고안의 바람직한 실시예를 상세하게 설명하겠다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
도3은 본 고안에 따른 밸런서가 장착된 세탁기의 내부구성을 보인 단면도이다. 이에 도시한 바와 같이, 세탁기는 본체케이스(10)와 본체케이스(10)의 내부에 현가된 고정조(11)와 고정조(11)의 내부에 회전자재로 설치된 회전조(12) 및 회전날개(13)를 포함한다. 고정조(11)는 수조역할을 하는데, 4개의 현가봉(16)에 의하여 본체케이스(10)에 현가된다. 그리고 회전조(12)는 고속회전하여 세탁물에 있는 물기를 원심분리시키는데, 이러한 회전조(12)의 측면에는 다수개의 통공(12a)이 형성되어 원심분리된 물기가 세탁에서 이탈되도록 한다. 회전날개(13)는 회전조(12)의 내부 저면에 회전가능하게 설치되어 세탁시 정역회전하여 수류를 형성시켜 수류에 의하여 세탁이 이루어지도록 한다. 고정조(11)의 하면 외측면에는 상기한 회전조(12)와 회전날개(13)를 회전시키기 위한 모터(14)가 설치되는데, 모터(14)와 이들 피구동체(12)(13)사이에는 클러치(15)가 개재된다.3 is a cross-sectional view showing the internal configuration of a washing machine equipped with a balancer according to the present invention. As shown in the drawing, the washing machine includes a fixed tub 11 suspended in the main body case 10 and a main body case 10 and a rotating tub 12 and a rotary wing installed in the inner side of the fixed tub 11. (13). The fixing tank 11 serves as a water tank, and is suspended in the main body case 10 by four suspension rods 16. Then, the rotating tub 12 rotates at a high speed to centrifuge the water in the laundry. A plurality of through holes 12a are formed on the side of the rotating tub 12 so that the centrifuged water is separated from the laundry. Rotating blade 13 is rotatably installed on the inner bottom surface of the rotating tub 12 to form a water flow by rotating forward and reverse during washing to be washed by the water flow. On the outer surface of the lower surface of the fixing tank 11, a motor 14 for rotating the rotating tank 12 and the rotary blade 13 is installed, and between the motor 14 and these driven bodies 12, 13 The clutch 15 is interposed.
한편 회전조(12)의 상단에는 회전조(12)의 회전시 발생하는 언밸런스를 감쇄시키기위한 밸런서(20)가 설치된다. 밸런서(20)는 회전조(12)와 동심을 이루는 환형의 홈(22)을 형성하는 케이스(21)와 홈(21)의 내부에 채워진 액체(23)를 포함한다. 케이스(21)는 회전조(12)의 상단부에 결합설치되며, 액체(23)는 홈(22)의 반 조금 넘게 채워지는데, 비중이 대략 1.21정도인 염수가 바람직하다. 그리고 이러한 밸런서(20)에는 회전조(12)의 고유진동수 이전에 액체가 이동하는 것을 억제하여 액체(23)에 의한 언밸랜서의 심화를 방지하기 위한 방지부재(24)가 설치된다. 방지부재(24)는 케이스(21)의 상하면과 평행하게 마련된 판상으로 이루어지는데, 방지부재(24)의 일단은 케이스(21)의 외측면 내측에 결합되고 타단은 자유단으로 마련된다. 방지부재(24)는 액체(23)의 표면보다 상측에 위치하도록 위치되고, 자유단은 회전조(12)의 회전수가 고유진동수 영역을 벗어나면 액체의 이동에 방해가 되지 않도록 적절하게 연장된다.On the other hand, a balancer 20 is installed at the upper end of the rotating tub 12 to reduce unbalance generated when the rotating tub 12 rotates. The balancer 20 includes a case 21 forming an annular groove 22 concentric with the rotating tank 12 and a liquid 23 filled in the groove 21. Case 21 is coupled to the upper end of the rotating tub 12, the liquid 23 is filled a little more than half of the groove 22, the specific gravity of about 1.21 is preferably salt water. In addition, the balancer 20 is provided with a preventing member 24 for preventing deepening of the unbalancer by the liquid 23 by preventing the liquid from moving before the natural frequency of the rotating tub 12. The prevention member 24 is formed in a plate shape parallel to the upper and lower surfaces of the case 21, one end of the prevention member 24 is coupled to the inside of the outer surface of the case 21 and the other end is provided as a free end. The prevention member 24 is positioned so as to be located above the surface of the liquid 23, and the free end is appropriately extended so that the rotation of the rotating tub 12 does not interfere with the movement of the liquid when it is out of the natural frequency region.
이와 같이 구성된 본 고안에 따른 세탁기의 밸런싱 작용에 대하여 설명하면 다음과 같다.Referring to the balancing action of the washing machine according to the present invention configured as described above are as follows.
회전조(12)가 고속회전하면 회전조(12)의 내부에 있는 세탁물에 원심력이 작용하여 세탁물에 함유되어 있던 물기가 원심분리시킨다. 원심분리된 물기가 통공(12a)을 통하여 고정조(11)로 이동함으로써 세탁물의 탈수가 이루어진다.When the rotating tub 12 rotates at a high speed, centrifugal force acts on the laundry inside the rotating tub 12 to centrifuge the water contained in the laundry. The centrifuged water moves to the fixing tank 11 through the through-hole 12a, whereby laundry is dewatered.
한편 회전조(12)의 회전시 세탁물의 편심에 의하여 언밸런스가 발생하는데, 이와 같은 언밸런스의 반대방향으로 액체(23)가 이동함으로써 언밸런스를 감쇄시킨다. 이러한 액체(23)는 회전 초기 언밸런스와 같은 방향으로 이동하다가 회전조(12)의 회전수가 고유진동수 영역을 벗어나면 비로소 언밸런스의 반대방향으로 이동하여 밸런싱작용을 하기 때문에 고유진동수 영역내에서는 언밸랜싱을 증가시킨다. 한편 본원고안은 도4에 도시한 바와 같이, 억제부재(24)가 고유진동수 영역내에서 이러한 액체(23)의 유동을 억제하기 때문에 회전 초기 액체에 의하여 언밸런싱력이 증가되는 것이 방지된다.On the other hand, unbalance occurs due to the eccentricity of the laundry when the rotating tub 12 rotates, and the unbalance is attenuated by the movement of the liquid 23 in the opposite direction of the unbalance. The liquid 23 moves in the same direction as the initial rotation unbalance, but when the rotation speed of the rotating tub 12 is out of the natural frequency region, the liquid 23 moves in the opposite direction of the unbalance to perform the balancing operation. Increase. On the other hand, the present application, as shown in Figure 4, because the restraining member 24 suppresses the flow of such a liquid 23 in the natural frequency region is prevented from increasing the unbalanced force by the initial rotation liquid.
이상에서 상세하게 설명한 바와 같이, 본 고안에 따른 세탁기의 밸런서는 밸런서의 케이스에 판상의 억제부재를 설치함으로써 액체가 고유진동수 범위내에서 이동하는 것을 억제함으로써 회전 초기 밸런서에 의하여 언밸런서가 심화되는 것을 방지할 수 있는 이점이 있다.As described in detail above, the balancer of the washing machine according to the present invention is provided with a plate-like suppressing member in the case of the balancer, thereby preventing the liquid from moving within the natural frequency range, thereby increasing the unbalancer by the initial rotational balancer. There is an advantage that can be prevented.
