As such, the viscous fluids contained in mutually different ball races have mutually different colors. This makes it possible to easily detect in which ball race the oil outflow occurred.
Description
본 고안은 복수의 볼레이스를 갖는 세탁기의 진동감쇠용 볼밸런서에 관한 것으로서, 특히, 볼밸런서내에 수용된 점성유체가 외부로 유출되었을 경우 어느 볼레이스에서 발생하였는지를 용이하게 검출할 수 있도록 점성유체에 고유의 색상과 상이한 색상을 갖게 한 것이다.The present invention relates to a ball balancer for vibration damping of a washing machine having a plurality of ball races, and in particular, inherent to viscous fluids so as to easily detect which ball race occurred in a viscous fluid contained in the ball balancer when it is leaked to the outside. It will have a different color from the color of.
세탁기는 외관을 구성하는 케이싱과, 케이싱내에서 다수의 서스팬션에 의해 지지되는 터브와, 터브내에 회전가능하게 수용되어 있는 탈수조를 가지고 있다. 이러한 세탁기의 세탁과정시 탈수조내에 수용된 세탁물이 고르게 분포하지 않고 어느정도 편중되어 있을경우 세탁과정중 탈수작동시 탈수조가 고속 작동하면, 이 편중된 세탁물에 의해 탈수조가 진동하게 된다. 탈수조의 진동이 발생하면 그 진동이 터브에 전달되고, 터브의 진동은 케이싱과 터브에 연결된 서스펜션에 의해 감쇠된다. 그러나, 서스펜션에 의한 진동감쇠는 2차적인 진동방지에 불과하므로, 진동원인 탈수조의 진동을 직접적으로 감쇠시키기 위하여, 도 1에 도시된 바와 같이, 볼밸런서를 널리 채용하고 있다.The washing machine has a casing constituting the exterior, a tub supported by a plurality of suspensions in the casing, and a dewatering tank rotatably housed in the tub. If the laundry contained in the dehydration tank during the washing process of the washing machine is not evenly distributed and somewhat decent, when the dehydration tank is operated at high speed during the dehydration operation during the washing process, the dewatering tank is vibrated by the unbalanced laundry. When the vibration of the dehydration tank occurs, the vibration is transmitted to the tub, and the vibration of the tub is attenuated by the casing and the suspension connected to the tub. However, since vibration attenuation due to suspension is only secondary vibration prevention, in order to directly attenuate the vibration of a dehydration tank which is a vibration source, a ball balancer is widely used as shown in FIG. 1.
볼밸런서(21)는 탈수조의 상부에 설치되며, 밸런서상판(22)과 밸런서하판(23)의 결합에 의해 환상의 중공체인 볼하우징을 형성하며, 밸런서상판(22)과 밸런서하판(23)의 사이에는 볼하우징을 상하로 구획하여 복수의 볼레이스(26)를 형성하는 밸런서분리판(27)이 결합되어 있다. 각 볼레이스(26)내에는 진동을 감쇠시키도록 구름이동하는 감쇠볼(24)이 수용되어 있고, 감쇠볼(24)은 점성을 갖는 오일(25)에 침지되어 있다. 여기서, 밸런서상판(22)과 밸런서하판(23) 및 밸런서분리판(27)은 용착에 의해 결합된다. 용착방법에는 결합부위를 열로 녹인 후 결합시키는 열용착과, 밸런서상판(22)과 밸런서하판(23) 및 밸런서분리판(27)을 맞대고 서로 상대회전시켜 접촉부에 마찰열을 발생시켜 녹인 후 결합시키는 스핀용착 등의 방법이 사용된다.The ball balancer 21 is installed on the upper side of the dehydration tank, and forms a ball housing which is an annular hollow body by the combination of the balancer upper plate 22 and the balancer lower plate 23, and the balancer upper plate 22 and the balancer lower plate 23. The balancer separating plate 27 which divides the ball housing up and down and forms the plurality of ball races 26 is coupled therebetween. In each of the ball races 26, damping balls 24 which move in a rolling manner to damp vibrations are accommodated, and the damping balls 24 are immersed in viscous oil 25. Here, the balancer upper plate 22, the balancer lower plate 23 and the balancer separator plate 27 are joined by welding. In the welding method, the thermal welding for melting and coupling the coupling parts with heat, and the balancer upper plate 22, the balancer lower plate 23 and the balancer separator plate 27 are rotated relative to each other to generate frictional heat at the contact portion to melt and spin Welding and the like are used.
이러한 볼밸런서(21)를 설치한 세탁기가 탈수작동을 개시하여 탈수조가 회전을 시작하면, 이에 따라 볼밸런서(21)도 회전을 시작한다. 볼밸런서(21)의 회전은 볼레이스(26)내에 수용된 감쇠볼(24)에 원심력을 가하게 되고, 탈수조 회전 개시 직후에 저속으로 회전할 때에는 감쇠볼(24)들에 의해 탈수조의 편중이 다소 심화되어 진동이 발생하지만, 회전속도가 증가하여 탈수조가 고속으로 회전하게 되면 볼레이스(26)내에서 감쇠볼(24)들이 원심력에 의해 재배치되어 탈수조내의 세탁물의 편중을 상쇄시키도록 균형을 이루게 된다. 이에 따라 탈수조의 균형이 유지되어 탈수조의 회전에 의한 진동이 현저하게 줄어들게 된다.When the washing machine provided with the ball balancer 21 starts the dehydration operation and the dehydration tank starts to rotate, the ball balancer 21 also starts to rotate. The rotation of the ball balancer 21 exerts a centrifugal force on the damping ball 24 accommodated in the ball race 26. When the ball balancer rotates at a low speed immediately after the rotation of the dehydration tank, the declination of the dehydration tank is slightly caused by the damping balls 24 As the vibration increases, but the rotational speed increases and the dehydration tank rotates at a high speed, the damping balls 24 are repositioned by centrifugal force in the ball race 26 to balance the laundry in the dehydration tank. do. As a result, the balance of the dehydration tank is maintained, thereby significantly reducing vibrations caused by the rotation of the dehydration tank.
이 때, 세탁기의 탈수조가 고속회전을 하면, 원심력에 의해 감쇠볼(24)들이 볼레이스(26)의 내벽면에 반경방향 외측으로 강한 힘을 가하게 된다. 이에 따라, 융착결합되어 있는 밸런서상판(22)과 밸런서분리판(27)사이 또는 밸런서분리판(27)과 밸런서하판(23) 사이에 틈새가 발생하게 되며, 또한, 융착결합시 완전한 융착이 이루어지지 않았을 경우에도 밸런서상판(22)과 밸런서분리판(27)사이 또는 밸런서분리판(27)과 밸런서하판(23) 사이에 틈새가 발생하게 되어 오일(25)이 탈수조내로 유출되게 된다.At this time, when the dehydration tank of the washing machine rotates at a high speed, the damping balls 24 apply a strong force radially outward to the inner wall surface of the ball race 26 by centrifugal force. Accordingly, a gap is generated between the balancer upper plate 22 and the balancer separation plate 27 or the balancer separation plate 27 and the balancer lower plate 23 that are fusion-bonded, and also complete fusion is performed at the time of fusion coupling. Even when not supported, a gap is generated between the balancer upper plate 22 and the balancer separator plate 27 or between the balancer separator plate 27 and the balancer lower plate 23 so that the oil 25 flows into the dehydration tank.
그런데, 이렇게 오일(25)이 탈수조내로 유출되어 의류에 오염이 되었을 경우 각 볼레이스(26)내의 오일(25)의 색상이 동일하므로, 어느 볼레이스(26)에서 오일(25)이 유출되었는지 여부를 판단하기 어려우며, 그 유출량이 미소할 때는 탈수조로 유출되더라도 오염여부를 찾아내기가 어렵다는 문제점이 있다.However, when the oil 25 is leaked into the dehydration tank and the clothes are contaminated, the color of the oil 25 in each ball race 26 is the same, so in which ball race 26 the oil 25 is leaked It is difficult to determine whether or not, and when the outflow is small, there is a problem that it is difficult to find whether or not it is contaminated even if it is spilled into the dehydration tank.
따라서 본 고안의 목적은, 볼밸런서의 오일이 유출된 경우, 오일의 유출여부와, 어느 볼레이스의 오일이 유출되었는지를 오일을 용이하게 검출할 수 있는 세탁기의 진동감쇠용 볼밸런서를 제공하는 것이다.Accordingly, an object of the present invention is to provide a ball balancer for vibration damping of a washing machine that can easily detect oil leakage of oil and whether ball oil is leaked when oil of the ball balancer is leaked. .

상기 목적은, 본 고안에 따라, 탈수조에 고리상으로 설치되는 복수의 볼레이스와, 상기 볼레이스내에 각각 수용되는 다수의 감쇠볼과, 상기 볼레이스내에 각각 수용되는 점성유체를 갖는 세탁기의 진동감쇠용 볼밸런서에 있어서, 상호 상이한 볼레이스내에 수용되는 상기 점성유체들은 상호 상이한 색상을 갖는 것을 특징으로 하는 세탁기의 진동감쇠용 볼밸런서에 의해 제공된다.The above object is, according to the present invention, a vibration damping of a washing machine having a plurality of ball races installed in a dehydration tank in a ring, a plurality of damping balls each accommodated in the ball race, and a viscous fluid respectively contained in the ball races. In the ball balancer, the viscous fluids contained in mutually different ball races are provided by a vibration damper ball balancer of the washing machine, characterized in that they have different colors from each other.
이하 첨부도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2는 세탁기의 단면도이다. 세탁기는 외관을 구성하는 케이싱(1)과, 케이싱(1)내에서 다수의 서스펜션(2)에 의해 지지되는 터브(3)와, 터브(3)내에 회전가능하게 수용되어 있는 탈수조(4)를 가지고 있다. 터브(3)의 하부에는 세탁기를 구동하는 구동모터(6)와, 구동모터(6)의 구동력을 탈수조(4)와 펄세이터(9)에 전달하는 샤프트조립체(5)가 설치되어 있다. 샤프트조립체(5)는 탈수조(4)의 하부에 고정되어 탈수조(4)를 회전지지하는 샤프트플랜지(10)에 의해 탈수조(4)에 연결되어 있다. 그리고, 샤프트플랜지(10)는 탈수조(4)의 하부에 견고하게 고정되어 있다. 이 샤프트플랜지(10)의 중앙부위는 샤프트조립체(5)의 샤프트와 결합되어 샤프트조립체(5)에 의해 지지된다. 구동모터(6)의 회전구동력은 벨트(7)에 의해 샤프트조립체(5)에 전달되며, 탈수작동시에는 샤프트조립체(5)의 샤프트에 의해 샤프트플랜지(10)에 전달되어 탈수조(4)와 펄세이터(9)를 회전시키고, 세탁작동시에는 탈수조(4)내에 설치된 펄세이터(9)에 전달하여 펄세이터(9)를 회전구동한다.2 is a cross-sectional view of the washing machine. The washing machine includes a casing 1 constituting an exterior, a tub 3 supported by a plurality of suspensions 2 in the casing 1, and a dewatering tank 4 rotatably housed in the tub 3. Have The lower part of the tub 3 is provided with a drive motor 6 for driving the washing machine and a shaft assembly 5 for transmitting the driving force of the drive motor 6 to the dehydration tank 4 and the pulsator 9. The shaft assembly 5 is connected to the dehydration tank 4 by a shaft flange 10 which is fixed to the lower part of the dehydration tank 4 and supports the dehydration tank 4 in rotation. And the shaft flange 10 is firmly fixed to the lower part of the dehydration tank (4). The central portion of the shaft flange 10 is coupled to the shaft of the shaft assembly 5 and supported by the shaft assembly 5. The rotational driving force of the drive motor 6 is transmitted to the shaft assembly 5 by the belt 7, and in the dehydration operation, it is transmitted to the shaft flange 10 by the shaft of the shaft assembly 5 so that the dehydration tank 4 is provided. And the pulsator 9 are rotated, and during the washing operation, the pulsator 9 is transmitted to the pulsator 9 installed in the dehydration tank 4 to rotate the pulsator 9.
이러한 세탁기의 탈수작동시 탈수조(4)내에는 세탁물이 고르게 분포되지 않고 어느정도 편중되어 분포되어 있으므로, 탈수조(4)가 고속으로 회전하면, 이 편중된 세탁물에 의해 탈수조(4)가 진동하게 된다. 탈수조(4)에 진동이 발생하면 그 진동이 터브(3)에 전달되고, 터브(3)의 서스펜션(2)에 의해 진동이 감쇠된다. 그러나, 진동이 심할 경우에는 서스펜션(2)의 진동감쇠력만으로는 부족하므로 볼밸런서(11)를 설치하여 진동을 감쇠시킨다. 이러한 볼밸런서(11)는 탈수조(4)의 상부에 길이방향으로 배열된 복수의 볼레이스(16)를 갖도록 설치되어 있다.In the dehydration operation of the washing machine, the laundry is not evenly distributed in the dehydration tank 4, so that the laundry is unevenly distributed to some extent. When the dewatering tank 4 rotates at high speed, the dewatering tank 4 vibrates due to the uneven laundry. Done. When vibration occurs in the dehydration tank 4, the vibration is transmitted to the tub 3, and the vibration is attenuated by the suspension 2 of the tub 3. However, when the vibration is severe, only the vibration damping force of the suspension 2 is insufficient, so that the ball balancer 11 is installed to damp the vibration. The ball balancer 11 is provided to have a plurality of ball races 16 arranged in the longitudinal direction on the upper side of the dehydration tank (4).
도 3은 볼밸런서의 부분 절취사시도이다. 볼밸런서(21)는 도 1에서 설명한 바와 같이, 밸런서상판(22) 및 밸런서하판(23)이 결합되어 고리상의 중공체인 볼하우징을 형성하며, 볼하우징은 밸런서상판(22)과 밸런서하판(23)의 사이에 결합되는 밸런서분리판(27)에 의해 상하로 형성된 볼레이스(26)로 이루어져 있다. 그리고, 각 볼레이스(26)내에는 진동을 감쇠하도록 구름이동하는 감쇠볼(24)이 수용되어 있고, 감쇠볼(24)은 점성을 갖는 오일(25)에 침지되어 있다. 여기서, 각 볼레이스(26)내에 수용된 감쇠볼(24)은 동일한 크기로 구성되며, 이에 따라 감쇠볼(24)의 진동감쇠를 돕는 오일(25)도 동일한 점도를 갖도록 마련된다. 이 때, 오일(25)은 고유의 색상과 상이한 색상을 갖도록 마련되며, 또한, 각 볼레이스(26)마다 수용된 오일(25)이 서로 상이한 색상을 갖도록 한다. 예를 들면, 상부 볼레이스(26)내의 오일(25a)은 빨간색을 갖도록 하고, 하부 볼레이스(26)내의 오일(25b)은 파란색을 갖도록 할 수 있다.3 is a partial cutaway perspective view of the ball balancer. As described in FIG. 1, the ball balancer 21 combines the balancer upper plate 22 and the balancer lower plate 23 to form a ball housing, which is a ring-shaped hollow body, and the ball housing has a balancer upper plate 22 and a balancer lower plate 23. It consists of a ball race 26 formed up and down by the balancer separator plate 27 coupled between. In each of the ball races 26, damping balls 24 which move in a cloud to damp vibrations are accommodated, and the damping balls 24 are immersed in oil 25 having viscosity. Here, the damping ball 24 accommodated in each ball race 26 is configured of the same size, and thus the oil 25 to help the vibration damping of the damping ball 24 is provided to have the same viscosity. At this time, the oil 25 is provided to have a different color from the original color, and also allows the oil 25 accommodated for each ball race 26 to have a different color from each other. For example, the oil 25a in the upper ball race 26 may have a red color, and the oil 25b in the lower ball race 26 may have a blue color.
이러한 볼밸런서(21)는, 세탁기가 탈수작동을 시작하여 탈수조(4)가 회전을 하면, 이에 따라 회전한다. 볼밸런서(21)가 회전하면, 볼레이스(26)내에 수용된 감쇠볼(24)에 원심력이 작용하여 감쇠볼(24)이 재배치되어 탈수조(4)내의 세탁물의 편중을 상쇄시켜 진동을 줄이게 된다.The ball balancer 21 rotates accordingly when the washing machine starts the dehydration operation and the dehydration tank 4 rotates. When the ball balancer 21 rotates, the centrifugal force acts on the damping ball 24 accommodated in the ball race 26, and the damping ball 24 is rearranged to offset the bias of the laundry in the dehydration tank 4 to reduce vibration. .
그런데, 탈수조(4)의 회전시 볼밸런서(21)의 감쇠볼(24)은 볼레이스(26)의 반경방향 외측면에 원심력을 가하게 되어 밸런서상판(22)과 밸런서하판(23) 사이에 틈새가 발생하거나, 융착불량으로 인하여 틈새가 발생하게 되면, 이 틈새로 탈수조(4)내로 오일(25)이 유출되는 경우가 생긴다. 이 때, 각 볼레이스(26)에 수용된 오일(25)은 볼레이스(26)마다 서로 상이한 색상을 가지도록 구성되어 있으므로, 탈수조(4)내로 유출된 오일(25)의 양이 미소하더라도 오일유출 유무를 용이하게 파악할 수 있으며, 어느 볼레이스(26)에서 오일(25)이 유출되었는지도 용이하게 검출할 수 있다.However, the damping ball 24 of the ball balancer 21 at the time of rotation of the dehydration tank 4 exerts a centrifugal force on the radially outer surface of the ball race 26 between the balancer upper plate 22 and the balancer lower plate 23. If a gap occurs or a gap occurs due to poor fusion, the oil 25 may flow out into the dewatering tank 4 by this gap. At this time, since the oil 25 contained in each ball race 26 is configured to have a different color for each ball race 26, even if the amount of oil 25 spilled into the dehydration tank 4 is minute The presence or absence of an outflow can be easily grasped, and it can be easily detected in which ball race 26 the oil 25 is outflowed.
도 4는 볼밸런서의 다른 예의 부분 절취사시도이고, 도 5는 도 4의 횡단면도이다. 볼밸런서(11)가 탈수조의 하부에 설치된 경우에, 도시된 바와 같이, 볼밸런서(11)는 밸런서상판(12)과 밸런서하판(13)의 결합에 의해 볼하우징을 형성하며, 볼하우징은 반경방향으로 배열된 복수의 볼레이스(16)로 이루어져 있다. 각 볼레이스(16)에는 진동을 감쇠시키는 다수의 감쇠볼(14)이 수용되어 있고, 감쇠볼(14)은 점성을 가지는 오일(15)에 침지되어 이동하게 된다. 여기서, 각 볼레이스(16)내의 감쇠볼(14)은 반경방향 외측의 볼레이스(16)로 갈수록 지름이 커지며, 이에 따라, 감쇠볼(14)이 진동감쇠를 효과적으로 할 수 있도록 반경방향 외측의 볼레이스(16)로 갈수록 오일(15)의 점도도 커진다. 그리고, 이 오일(15)은 상술한 예에서와 같이, 볼레이스(16)마다 상이한 색상을 갖도록 구성되어 있다. 예를 들면, 반경방향 외측의 볼레이스(16)의 오일(15a)은 파란색을 갖도록 하고, 중앙의 볼레이스(16)의 오일(15b)은 빨간색을, 내측의 볼레이스(16)의 오일(15c)은 녹색을 갖도록 한다. 이에 따라, 탈수조(4)의 진동감쇠에 이상이 생기면, 각 볼레이스(16)내의 오일(15)을 취하여 정해진 색상과의 변색정도를 비교하면 용이하게 오일(15)의 유출여부를 판별할 수 있다. 또한, 오일(15)이 외부로 유출되었을 경우에도 오일(15)이 색상을 갖고 있으므로 용이하게 파악할 수 있다.4 is a partial cutaway perspective view of another example of a ball balancer, and FIG. 5 is a cross-sectional view of FIG. 4. When the ball balancer 11 is installed in the lower part of the dehydration tank, as shown, the ball balancer 11 forms a ball housing by the combination of the balancer upper plate 12 and the balancer lower plate 13, and the ball housing has a radius It consists of a plurality of ball races 16 arranged in the direction. Each ball race 16 accommodates a plurality of damping balls 14 for damping the vibrations, and the damping balls 14 are immersed in the oil 15 having viscosity to move. Here, the damping balls 14 in the respective ball races 16 are larger in diameter toward the ball races 16 in the radially outer side, and thus, the damping balls 14 in the radially outer side can effectively damp the vibrations. The viscosity of the oil 15 also increases toward the ball race 16. And this oil 15 is comprised so that it may have a different color for every ball race 16 like the above-mentioned example. For example, the oil 15a of the ball race 16 in the radially outer side has a blue color, the oil 15b of the ball race 16 in the center is red, and the oil of the ball race 16 in the inner side ( 15c) has a green color. Accordingly, when an abnormality occurs in the vibration damping of the dehydration tank 4, taking oil 15 in each ball race 16 and comparing the degree of discoloration with a predetermined color, it is possible to easily determine whether the oil 15 is leaked. Can be. In addition, since the oil 15 has a color even when the oil 15 is leaked to the outside, it can be easily grasped.
상기 실시예들에서는 복수의 볼레이스를 갖는 볼밸런서를 설치한 경우에 대해 상세히 설명하였으나, 예컨대, 탈수조(4)의 상부나 하부에 단일의 볼레이스를 갖는 볼밸런서를 설치한 경우에도 오일이 색상을 갖도록 하므로서, 탈수조(4)내로 오일이 유출되었을 때 용이하게 유출을 검출할 수 있다.In the above embodiments, a case in which a ball balancer having a plurality of ball races is installed has been described in detail. For example, even when a ball balancer having a single ball race is installed in the upper or lower portion of the dehydration tank 4, By having a color, an outflow can be detected easily when oil leaks into the dehydration tank 4. As shown in FIG.
이상 설명한 바와 같이, 본 고안에 따르면, 볼밸런서내의 어느 볼레이스에서 오일이 유출되었는지를 용이하게 검출할 수 있다.As described above, according to the present invention, it is possible to easily detect which ball race in the ball balancer is leaked.
