본 고안은 세탁기의 세탁조 진동 감쇠용 볼밸런서에 관한 것이다.The present invention relates to a ball balancer for damping the vibration of the washing machine of the washing machine.

세탁물을 수용하여 세탁 및 탈수 작동을 행하는 세탁기는 제3도에 도시된 바와 같다. 제3도는 볼밸런서를 갖는 종래의 세탁기의 측단면도이고, 제4도는 제3도의 볼밸런서의 부분확대단면도이다. 세탁기는 외관을 구성하는 아웃케이싱(51)과, 아웃케이싱(51)내에서 다수의 서스펜션(59)에 의해 지지되어 있는 아웃터브(53)와, 아웃터브(53) 내에 회전가능하게 수용되어 있는 탈수조(55)를 가지고 있다. 아웃터브(51)의 하부에는 샤프트조립체(57)가 설치되어 샤프트를 통해 탈수조(55) 또는 탈수조(55) 내에 설치된 펄세이터(56)를 회전구동한다. 세탁작동시에는 펄세이터(56)가 회전하고 탈수조(55)는 고정되어 있으며, 탈수작동시에는 탈수조(55)가 회전한다. 탈수조(55)내에 수용된 세탁물은 탈수조(55) 내에서 고르게 분포되지 않고 어느정도 편중되어 분포되어 있으므로, 탈수작동시에 탈수조(55)가 고속으로 회전하면, 이 편중된 세탁물에 의해 탈수조(55)가 고속으로 회전하면, 이 편중된 세탁물에 의해 탈수조(55)가 진동을 하게 된다. 탈수조(55)의 진동이 발생하게 되면 그 진동이 아웃터브(53)에 전달되고 서스펜션(59)에 의해 진동이 감쇠된다. 그러나, 진동이 심할 경우에는 서스펜션(59)의 진동감쇠력만으로는 부족하므로 여러가지의 진동감쇠장치가 장차되어 사용되고 있다.A washing machine that accommodates laundry and performs washing and dewatering operations is as shown in FIG. 3 is a side cross-sectional view of a conventional washing machine having a ball balancer, and FIG. 4 is a partially enlarged cross-sectional view of the ball balancer of FIG. The washing machine is rotatably housed in the out casing 51 constituting the exterior, the out tub 53 supported by the plurality of suspensions 59 in the out casing 51, and the out tub 53. It has a dehydration tank 55. A shaft assembly 57 is installed below the outer tub 51 to rotate and drive the dehydration tank 55 or the pulsator 56 installed in the dehydration tank 55 through the shaft. In the washing operation, the pulsator 56 is rotated and the dehydration tank 55 is fixed. In the dehydration operation, the dehydration tank 55 is rotated. Since the laundry contained in the dehydration tank 55 is not evenly distributed in the dehydration tank 55, but is partially biased and distributed, the dehydration tank 55 rotates at high speed during the dehydration operation. When 55 is rotated at high speed, the dewatering tank 55 vibrates by this uneven laundry. When the vibration of the dehydration tank 55 is generated, the vibration is transmitted to the outer tub 53 and the vibration is attenuated by the suspension 59. However, when the vibration is severe, only the vibration damping force of the suspension 59 is insufficient, and various vibration damping devices are used in the future.

이러한 진동감쇠장치로서 사용되는 것 중 하나가 볼밸런서이다. 볼밸런서(40)는 환상의 중공체로 된 볼하우징을 가지고 있고, 볼하우징 내에는 진동 감쇠용으로 사용되는 감쇠볼(45)이 다수 수용되어 있다. 볼하우징은 감쇠볼(45)의 구름 이동을 안내하는 공간을 제공한다. 볼하우징은 플라스틱 재질로 형성되어 있으며, 상부볼하우징(41)과 하부볼하우징(43)으로 구성된다. 상부볼하우징(41)과 하부볼하우징(43)은 용착에 의해 결합된다. 상하부볼하우징(41,42)간의 용착방법에는 결합부위를 열로 녹인 후 결합시키는 열용착, 또는 상부볼하우징(41)과 하부볼하우징(43)을 맞대고 서로 상대회전시켜 접촉부에 마찰열을 발생시켜 녹인 후 결합시키는 스핀용착 등의 방법이 사용된다. 볼하우징 내에는 오일 등과 같은 점성이 있는 유체(47)가 수용된다. 볼밸런서(40)의 외벽면에는 반경방향으로 돌출부(46)가 외향돌출형성되어 있다.One of those used as such vibration damping device is a ball balancer. The ball balancer 40 has a ball housing made of an annular hollow body, and a plurality of damping balls 45 used for vibration damping are housed in the ball housing. The ball housing provides a space for guiding the rolling movement of the damping ball 45. The ball housing is formed of a plastic material, and consists of an upper ball housing 41 and a lower ball housing 43. The upper ball housing 41 and the lower ball housing 43 are combined by welding. In the welding method between the upper and lower ball housings (41, 42), the heat welding to melt the coupling portion by heat and then combine, or the upper ball housing 41 and the lower ball housing 43 are rotated relative to each other to generate frictional heat at the contact portion melted Post-bonding methods such as spin welding are used. A viscous fluid 47, such as oil, is accommodated in the ball housing. On the outer wall surface of the ball balancer 40, a protrusion 46 is formed to protrude outward in the radial direction.

볼밸런서(40)는 탈수조(55) 상부에 설치되어 있다. 볼밸런서(40)는 돌출부(46)가 탈수조(55)의 상측연부에 걸린 상태로 탈수조(55) 위에 놓여지며, 탈수조(55)의 외벽면으로부터 볼트에 의해 체결되어 탈수조(55)에 결합된다. 세탁기가 탈수작동을 개시하면 탈수조(55)는 회전을 시작하고, 이에 따라 볼밸런서(40)도 회전을 시작한다. 볼밸런서(40)의 회전은 볼하우징 내에 수용된 감쇠볼(45)에 원심력을 가하게 되고, 탈수조(55) 회전 개시 직후에 저속으로 회전할 때에는 감쇠볼(45)들에 의해 탈수조의 편중이 심하게 되어 진동이 발생하지만, 회전속도가 증가하여 탈수조(55)가 고속으로 회전을 하게 되면 볼하우징 내에서 감쇠볼(45)들이 원심력에 의해 재배치되어 탈수조(55) 내의 세탁물의 편중을 상쇄시키도록 균형을 이루게 된다. 이에 따라 탈수조(55)의 균형이 유지되어 탈수조(55) 회전에 의한 진동이 현저하게 줄어들게 된다.The ball balancer 40 is installed above the dehydration tank 55. The ball balancer 40 is placed on the dehydration tank 55 with the protrusion 46 caught on the upper edge of the dehydration tank 55, and is fastened by bolts from the outer wall surface of the dehydration tank 55 to dehydrate the tank 55. ) Is combined. When the washing machine starts the dehydration operation, the dehydration tank 55 starts to rotate, and accordingly, the ball balancer 40 also starts to rotate. The rotation of the ball balancer 40 exerts a centrifugal force on the damping ball 45 accommodated in the ball housing. When the ball balancer rotates at a low speed immediately after the rotation of the dehydrating tank 55 is rotated, the dehydration ball 45 is heavily biased. When the vibration occurs, but the rotational speed increases and the dehydration tank 55 rotates at a high speed, the damping balls 45 are repositioned by centrifugal force in the ball housing to offset the bias of the laundry in the dehydration tank 55. To be balanced. Accordingly, the balance of the dehydration tank 55 is maintained, thereby significantly reducing vibrations caused by the rotation of the dehydration tank 55.

그런데, 이러한 종래의 볼밸런서는, 상부볼하우징(41)과 하부볼하우징(43)을 용착시켜서 결합시키므로 결합부위가 용착에 의해 녹아내려 매끄럽지 못한 비어(burr)(49)가 생기게 되어, 볼밸런서의 진동 감쇠 효과가 양호하지 못하게 된다는 문제점이 있다. 탈수조(55)가 회전하여 볼밸런서(40)내의 감쇠볼(45)들이 이동을 하게 되면 감쇠볼(45)들은 원심력에 의해 볼하우징의 반경방향의 외측벽쪽으로 힘을 받아 편심되게 되므로 버어(49)에 감쇠볼(45)들이 접한 상태로 이동하므로 버어(49)가 마모되면서 불순물이 생기게 되고, 또한 감쇠볼(45)들의 이동이 버어(49)에 의해 걸리어 유연하게 이루어지지 못하므로 진동의 감쇠를 위한 볼밸런서(40)의 균형이 잘 이루어지지 않게 된다.By the way, such a conventional ball balancer, by welding the upper ball housing 41 and the lower ball housing 43 to combine, so that the coupling part is melted by welding, resulting in a smooth (burr) 49, the ball balancer There is a problem that the vibration damping effect is not good. When the dehydration tank 55 rotates and the damping balls 45 in the ball balancer 40 are moved, the damping balls 45 are eccentrically driven by the centrifugal force toward the radial outer wall of the ball housing. The damping ball 45 is moved in contact with the damper, so that the burrs 49 are worn and impurities are generated. Also, the damping balls 45 are not caught by the burrs 49 and are not made to be flexible. The balance of the ball balancer 40 for attenuation is not well achieved.

따라서, 본 고안의 목적은, 상부볼하우징과 하부볼하우징의 용착에 의해 생기는 버어에 의해 감쇠볼들의 이동이 저지되는 것을 방지하고 용착부위의 마모에 의한 불순물의 발생을 막을 수 있는 볼밸런서를 제공하는 것이다.Accordingly, an object of the present invention is to provide a ball balancer that can prevent the movement of damping balls by the burr caused by welding of the upper ball housing and the lower ball housing, and prevent the generation of impurities due to wear of the welding site. It is.

상기 목적은, 본 고안에 따라, 회전구동에 의해 세탁물의 탈수작동을 행하는 세탁조에 고리상으로 설치되어 다수의 진동 감쇠용 감쇠볼을 유동가능하게 수용하는 볼하우징을 갖는 세탁기용 볼밸런서 있어서, 상기 볼하우징은 상호 결합되어 상기 감쇠볼의 수용공간을 형성하는 상부볼하우징과 하부볼하우징 부분으로 이루어지며, 상기 상부볼하우징은 상기 하부볼하우징의 반경방향 외측내벽면의 내측에 상기 내벽면과 평행하도록 하향연장형성되어 상기 감쇠볼과 접촉하는 리브를 포함하는 것을 특징으로 하는 볼밸런서에 의해 달성된다.The above object is, according to the present invention, a ball balancer for a washing machine having a ball housing that is installed in a ring in a laundry tank for dehydration operation of the laundry by a rotational drive to accommodate a plurality of vibration damping balls in a fluid manner, wherein The ball housing is composed of an upper ball housing and a lower ball housing portion coupled to each other to form a receiving space of the damping ball, and the upper ball housing is parallel to the inner wall surface inside the radially outer inner wall surface of the lower ball housing. It is achieved by a ball balancer, characterized in that it comprises a rib extending downwardly in contact with the damping ball.

이하에서는 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 볼밸런서를 갖는 세탁기의 측단면도이고, 제2도는 제1도의 볼밸런서의 부분확대단면도이다. 볼밸런서(20)의 볼하우징은 상부볼하우징(21)과 하부볼하우징(23)으로 구성되어 있다. 상부볼하우징(21)에는 판면으로부터 하향연장된 리브(10)가 형성되어 있으며, 리브(10)는 하부볼하우징(23)의 외측내벽면과 소정 이격된 상태로 내벽면과 평행하게 하향연장되어 상부볼하우징(21)과, 하부볼하우징(23)을 용착시킬 때 발생하는 버어(29)를 가린다. 이때, 리브(10)의 하향연장 길이는 버어(29)를 감쇠볼(25)에 대해 가리는 정도면 족하지만, 충분한 길이로 연장되어 감쇠볼(25)의 측부를 지지할 수 있는 정도이면 더욱 바람직하므로, 하부볼하우징(23)으로부터 리브(10)의 하측단부까지의 높이가 감쇠볼(25)의 반경보다 작게 되도록 하여 감쇠볼(25)의 측면이 하부볼하우징(23)의 외측벽에 부딪치는 것을 효과적으로 방지하도록 한다.1 is a side cross-sectional view of a washing machine having a ball balancer according to the present invention, and FIG. 2 is a partially enlarged cross-sectional view of the ball balancer of FIG. The ball housing of the ball balancer 20 is composed of an upper ball housing 21 and a lower ball housing 23. The upper ball housing 21 is formed with a rib 10 extending downward from the plate surface, the rib 10 is extended downward in parallel with the inner wall surface in a predetermined spaced state with the outer inner wall surface of the lower ball housing 23. The upper ball housing 21 and the burr 29 generated when welding the lower ball housing 23 are covered. At this time, the length of the downward extension of the rib 10 is enough to cover the burr 29 with respect to the damping ball 25, but is more preferably extended to a sufficient length to support the side of the damping ball 25. Therefore, the height from the lower ball housing 23 to the lower end of the rib 10 is smaller than the radius of the damping ball 25 so that the side surface of the damping ball 25 hits the outer wall of the lower ball housing 23. To prevent them effectively.

세탁조(5)의 회전에 의해 볼밸런서(20)가 회전할 때, 감쇠볼(25)들은 원심력에 의해 하부볼하우징(23)의 외측벽을 향하는 힘을 받으면서 볼하우징 내에서 이동하게 된다. 이때 감쇠볼(25)들의 측면은 리브(10)에 접하게 되므로 버어(29)에 접하지 않게 되고, 따라서 감쇠볼(25)들의 이동이 리브(10)의 표면을 따라 유연하게 이루어지며, 버어(29)와 감쇠볼(25)의 부딪침에 의한 마모가 생기지 않게 되므로 불순물이 발생하지 않게 된다.When the ball balancer 20 is rotated by the rotation of the washing tub 5, the damping balls 25 are moved in the ball housing while receiving a force toward the outer wall of the lower ball housing 23 by centrifugal force. At this time, the side of the damping ball 25 is in contact with the rib 10, so that it is not in contact with the burr 29, and thus the movement of the damping ball 25 is made flexible along the surface of the rib 10, the burr ( 29) wear and tear due to the collision between the damping ball 25 is not generated impurities.

이상 설명한 바와 같이, 본 고안에 따르면, 상부볼하우징과 하부볼하우징의 용착에 의해 생기는 버어와 감쇠볼들의 접촉이 상부볼하우징으로부터 하향연장형성된 리브에 의해 방지되어, 볼하우징내에서의 감쇠볼들의 이동이 유연하게 이루어지고 버어의 마모에 의한 불순물의 발생이 방지되어 볼밸런서의 세탁조 진동 감쇠 기능이 효과적으로 이루어지게 된다.As described above, according to the present invention, the contact between the burr and the damping balls caused by the welding of the upper ball housing and the lower ball housing is prevented by the rib extending downward from the upper ball housing, so that the damping balls in the ball housing Since the movement is made smoothly and the occurrence of impurities due to the wear of the burr is prevented, the washing tank vibration damping function of the ball balancer is effectively performed.
