Description
본 고안은, 탈수조의 하부에 볼평형장치를 갖는 세탁기에 관한 것으로서, 보다 상세하게는, 탈수조와 볼평형장치가 견고하게 결합하여 볼평형장치의 유격을 방지할 수 있으며, 제작 공정이 단순하게 할 수 있도록 한 세탁기에 관한 것이다.The present invention relates to a washing machine having a ball balancing device in the lower part of the dewatering tank, and more specifically, the dewatering tank and the ball balancing device can be firmly combined to prevent the play of the ball balancing device, and to simplify the manufacturing process. It's about making a washing machine.
세탁기는 외관을 구성하는 본체와, 본체 내에서 다수의 현가장치에 의해 지지되어 있는 외조와, 외조 내에 회전가능하게 수용되어 있는 탈수조를 가지고 있다. 탈수조 내에 수용된 세탁물은 탈수조 내에서 고르게 분포되지 않고 어느정도 편중되어 분포되어 있으므로, 탈수작동시에 탈수조가 고속으로 회전하면, 이 편중된 세탁물에 의해 탈수조가 진동을 하게 된다. 탈수조의 진동이 발생하게 되면 그 진동이 외조에 전달되고, 외조의 진동은 현가장치에 의해 감쇠된다. 그러나, 진동이 심할 경우에는 현가장치의 진동감쇠력만으로는 부족하므로 여러 가지의 진동감쇠장치가 장착되어 사용되고 있다.The washing machine has a main body constituting the exterior, an outer tub supported by a plurality of suspension devices in the main body, and a dehydrating tank rotatably housed in the outer tub. Since the laundry contained in the dehydration tank is not evenly distributed in the dehydration tank and is distributed to some extent, when the dehydration tank rotates at a high speed during the dehydration operation, the dewatering tank vibrates by the deflated laundry. When the vibration of the dehydration tank occurs, the vibration is transmitted to the outer tank, the vibration of the outer tank is attenuated by the suspension device. However, when the vibration is severe, only the vibration damping force of the suspension device is insufficient, so that various vibration damping devices are mounted and used.
이러한 진동감쇠장치로서 사용되는 것 중 하나가 볼평형장치이다. 볼평형장치는 탈수조의 상부 또는 하부에 설치되어 탈수조의 회전시 세탁물의 편중에 의한 탈수조 무게의 편중을 상쇄시켜 탈수조의 진동을 감쇠시키는 장치로서, 제2도에 도시된 바와 같다. 제2도는 탈수조의 하부에 설치되는 볼평형장치의분해사시도이다. 볼평형장치(40)는 중공의 원형평판으로 된 평형장치상판(41)과, 평형장치상판(41)의 하부에 접합되는 평형장치하판(42)을 가지고 있고, 평형장치하판(42)에는 진동감쇠용의 다수의 감쇠볼(45)이 수용된다. 평형장치하판(42)은 감쇠볼(45)의 구름이동을 안내하는 볼그루브(47)를 형성하며, 볼그루브(47) 내에는 오일 등과 같은 점성이 있는 유체가 수용된다.One of those used as such vibration damping devices is a ball balancing device. Ball balancing device is installed on the upper or lower portion of the dehydration tank to offset the deflection of the weight of the dehydration tank by the weight of the laundry during the rotation of the dehydration tank to attenuate the vibration of the dehydration tank, as shown in FIG. 2 is an exploded perspective view of the ball balancer installed in the lower part of the dehydration tank. The ball balancer 40 has a balancer upper plate 41 made of a hollow circular flat plate, and a balancer lower plate 42 joined to a lower portion of the balancer upper plate 41, and the balancer lower plate 42 is vibrated. A plurality of damping balls 45 for damping are accommodated. The balancer lower plate 42 forms a ball groove 47 for guiding the rolling movement of the damping ball 45, and a viscous fluid such as oil is contained in the ball groove 47.
한편, 제3도는 볼평형장치를 갖는 종래의 세탁기의 부분확대 측단면도로서, 탈수조의 하부에 볼평형장치 세탁기를 도시한 것이다. 세탁기는 외관을 구성하는 도시하지 않은 본체 내에 지지되어 있는 외조(51)와, 외조(51) 내에 회전가능하게 수용되어 있는 탈수조(55)를 가지고 있다.On the other hand, Figure 3 is a partially enlarged side cross-sectional view of a conventional washing machine having a ball balancing device, showing the ball balancing device washing machine in the lower part of the dewatering tank. The washing machine has an outer tub 51 supported in a main body (not shown) constituting the exterior, and a dehydration tank 55 rotatably housed in the outer tub 51.
외조(51)의 하부에는 구동모터(61)와 회전축조립체(63)가 설치되어 있다. 구동모터(61)의 회전구동력은 벨트(67)를 통해 회전축조립체(63)에 전달되고, 회전축조립체(63)는 이 회전구동력을 탈수조(55) 또는 탈수조(55) 내에 설치된 회전날개(58)에 전달된다. 세탁작동시에는 탈수조(55)는 정지한 상태로 회전날개(58)만 회전구동하고, 탈수작동시에는 탈수조(55)가 회전한다.The lower part of the outer tank 51, the drive motor 61 and the rotary shaft assembly 63 is provided. The rotary driving force of the drive motor 61 is transmitted to the rotary shaft assembly 63 through the belt 67, and the rotary shaft assembly 63 transmits the rotary driving force in the dehydration tank 55 or the dehydration tank 55. 58). During the washing operation, only the rotary blade 58 is rotated while the dehydration tank 55 is stopped. In the dehydration operation, the dehydration tank 55 rotates.
또한, 탈수조(55)와 회전축조립체(63)는 회전축고정부(65)에 의해 연결된다. 회전축고정부(65)는 탈수조(55)의 하부에 견고하게 고정되며, 회전축고정부(65)의 중앙부위는 회전축조립체(63)의 회전축(66)과 형상맞춤하여 결합된 상태로 회전축조립체(63)에 의해 지지한다. 구동모터(61)에 의해 회전축조립체(63)의 회전축(66)이 회전구동을 하면, 그 구동력은 회전축고정부(65)에 전달되어 회전축고정부(65)가 회전하게 되고 이에 따라 탈수조(55)가 회전을 하게 된다.In addition, the dehydration tank 55 and the rotating shaft assembly 63 are connected by the rotating shaft fixing part (65). The rotating shaft fixing part 65 is firmly fixed to the lower part of the dehydration tank 55, and the central portion of the rotating shaft fixing part 65 is fitted to the rotating shaft assembly of the rotating shaft assembly 63 in a state of being coupled to the rotating shaft assembly. Supported by (63). When the rotating shaft 66 of the rotating shaft assembly 63 is driven by the driving motor 61, the driving force is transmitted to the rotating shaft fixing part 65 so that the rotating shaft fixing part 65 rotates, thereby dehydrating tank ( 55) will rotate.
볼평형장치(40)는 회전축고정부(65)의 하부에 설치되어 있다. 회전축조립체(63)의 회전축(66)은 볼평형장치(40)의 중앙부위를 관통하여 회전축고정부(65)에 결합되며, 평형장치상판(41)은 회전축고정부(65)에 볼트 등에 의해 체결되어 결합된다. 이때 탈수조(55)와 외조(51) 사이의 좁은 공간에 볼평형장치(40)가 설치되기 위해서 탈수조(55)는 하부의 둘레구간이 상향하여 함몰 형성되고 회전축고정부(65)도 이에 형상맞춤하도록 절곡되어 형성된다.The ball balancing device 40 is installed in the lower part of the rotation shaft fixing part 65. The rotating shaft 66 of the rotating shaft assembly 63 passes through the central portion of the ball balancing device 40 and is coupled to the rotating shaft fixing part 65, and the balancing device upper plate 41 is connected to the rotating shaft fixing part 65 by bolts or the like. Fastened and combined. At this time, in order to install the ball balancer 40 in a narrow space between the dehydration tank 55 and the outer tank 51, the dehydration tank 55 is formed to be recessed with the circumferential section of the lower portion upward, and the rotation shaft fixing part 65 is also attached thereto. It is bent to form a shape.
그런데 이러한 종래의 세탁기에 있어서, 볼평형장치는 평형장치상판 및 평형장치하판이 플라스틱 재질로 구성되어 있어, 회전축고정부의 하부에 결합될 때 볼트에 의해 체결하는 방식을 사용하게 되어 결합이 견고하지 못하다는 단점이 있다. 또한, 탈수조가 고속으로 회전하여 강한 진동이 생길 때 볼트가 풀리는 현상이 발생하게 되면, 볼평형장치가 탈수조와 일체로 회전하지 못하고 흔들리게 되어 결합부위가 더욱 더 풀리게 되고 흔들림은 더 커지게 된다. 이에 따라 볼평형장치가 기능을 원활하게 수행하지 못하게 된다.By the way, in the conventional washing machine, the ball balancer is made of a plastic material of the balancer top plate and the balancer bottom plate, when using the method of fastening by bolts when coupled to the lower portion of the rotating shaft fixing unit is not firmly coupled. There is a drawback to this. In addition, when the dewatering tank rotates at a high speed to cause the bolt to loosen when a strong vibration occurs, the ball balancer is not rotated integrally with the dewatering tank and shakes, so that the coupling portion is further loosened and the shaking becomes larger. As a result, the ball balancer does not perform its function smoothly.
또한, 볼평형장치는 탈수조의 하부에 고정된 회전축고정부와 외조 사이에 설치되어 있으므로, 볼평형장치가 설치되는 공간을 확보하기 위해서는 회전축고정부의 외측단부가 탈수조의 형상에 맞게 상향하여 절곡된 형상으로 별도 제조되어야 하므로 제작 공정이 복잡하게 된다.In addition, since the ball balancer is installed between the rotary shaft fixing unit and the outer tank fixed to the lower part of the dehydration tank, in order to ensure the space for the ball balancing device is installed, the outer end of the rotating shaft fixing unit is bent upwards to match the shape of the dehydration tank. The manufacturing process is complicated because it needs to be manufactured separately in a shape.
따라서, 본 고안의 목적은, 탈수조의 하부에 설치되는 볼평형장치의 결합력을 강화하여 볼평형장치의 기능을 강화시키고, 별도의 회전축고정부를 제작할 필요없이 종래의 회전축고정부를 사용하여 볼평형장치를 설치할 수 있는 세탁기를 제공하는 것이다.Therefore, the object of the present invention is to enhance the function of the ball balancer by reinforcing the coupling force of the ball balancer installed in the lower part of the dehydration tank, the ball balance using a conventional rotation shaft fixing unit without the need to manufacture a separate rotation shaft fixing unit It is to provide a washing machine to install the device.

And a plurality of damping balls for the dragon and a ball balancer housed in the lower plate of the balancer and welded to the dehydration tank with the viscous fluid in which the damping balls are immersed.
여기서, 상기 평형장치상판은 상기 탈수조와 일체로 형성하는 것이 효과적일 수 있다.Here, it can be effective to form the balancer top plate integrally with the dehydration tank.
이하에서는 첨부도면을 참조하여 본 고안에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.
제1도는 본 고안에 따른 불평형장치를 갖는 세탁기의 부분확대 측단면도이다. 이 도면에 도시된 바와 같이, 탈수조(25)는 적어도 하부가 금속성 재질로 형성되어 있으며, 볼평형장치(10)의 평형장치상판(11) 및 평형장치하판(12)도 금속성재질로 형성되어 있다. 볼평형장치(10)는 탈수조(25)의 하부에 직접 설치되며, 회전축고정부(35)는 볼평형장치의 하부에 설치된다. 탈수조(25)의 하부는 고리상의 볼평형장치(10)가 형성맞춤할 수 있도록 함몰 형성되어 있다. 이에 따라 탈수조(25)의 하부의 중앙부 영역은 볼평형장치(10)의 중앙부를 통해 노출되어 회전축고정부(35)와 결합되는 부위를 제공하여, 볼트(36) 등에 의해 회전축고정부(35)와 탈수조(15)가 체결되어 결합된다. 평형장치상판(11)과 탈수조(25)는 용접에 의해 결합된다. 평형장치상판(11) 및 탈수조(25)가 금속성 재질로 형성되므로 용접이 가능하게 되고, 평형장치상판(11)과 탈수조(25)가 강하게 결합된다.1 is a partially enlarged side cross-sectional view of a washing machine having an unbalance device according to the present invention. As shown in this figure, the dehydration tank 25 is formed at least in the bottom of the metallic material, the balancer upper plate 11 and the balancer lower plate 12 of the ball balancing device 10 is also formed of a metallic material have. The ball balancing device 10 is directly installed in the lower portion of the dehydration tank 25, the rotating shaft fixing portion 35 is installed in the lower portion of the ball balancing device. The lower part of the dewatering tank 25 is recessed so that the ring-shaped ball balancing device 10 can be formed and fitted. Accordingly, the central region of the lower portion of the dewatering tank 25 is exposed through the central portion of the ball balancer 10 to provide a portion that is engaged with the rotation shaft fixing portion 35, and the rotation shaft fixing portion 35 by the bolt 36 or the like. ) And the dehydration tank 15 is fastened and coupled. The balancer top plate 11 and the dehydration tank 25 are joined by welding. Since the balancer top plate 11 and the dehydration tank 25 are formed of a metallic material, welding is possible, and the balancer top plate 11 and the dehydration tank 25 are strongly coupled.
바람직하게는, 탈수조(25)와 평형장치상판(11)을 일체로 제작한다. 이 경우 탈수조(25)의 하부 둘레구간은 평형장치하판(12)과 결합될 수 있는 형상으로 탈수조(25) 일체로 제작되며, 평형장치하판(12)을 탈수조(25)의 하부에 용접 등에 의해 융착시킴으로써 볼평형장치(10)의 설치가 완료된다. 이러한 방식에 의하면, 탈수조(25)에 평형장치상판(11)을 용접시키지 않고도 볼평형장치(10)를 더욱 강하게 고정시킬 수 있어 탈수조(25)의 고속 회전시 볼평형장치(10)와 탈수조(25)간의 결합부위가 이격되는 일이 발생하지 않게 되며, 제작 및 조립 공정을 더욱 단순화시킬 수 있다. 또한 볼평형장치(10)가 모두 금속성 재질로 구성되므로, 탈수조(25)의 고속 회전시 볼평형장치(10) 내의 감쇠볼들의 원심력에 의해 볼평형장치(10)의 외형이 변화되는 것을 방지할 수 있는 효과를 부수적으로 얻을 수 있다.Preferably, the dehydration tank 25 and the balancer upper plate 11 are manufactured integrally. In this case, the lower circumferential section of the dehydration tank 25 is made of a dehydration tank 25 in a shape that can be combined with the balancer lower plate 12, and the balancer lower plate 12 is disposed below the dehydration tank 25. The welding of the ball balancer 10 is completed by welding by welding. According to this method, the ball balancer 10 can be more firmly fixed without welding the balancer upper plate 11 to the dehydration tank 25 so that the ball balancer 10 and the ball balancer 10 can be rotated at high speed of the dehydration tank 25. The separation between the coupling parts of the dehydration tank 25 does not occur, and can further simplify the manufacturing and assembly process. In addition, since the ball balancing device 10 is all made of a metallic material, it prevents the appearance of the ball balancing device 10 from being changed by the centrifugal force of the damping balls in the ball balancing device 10 during the high speed rotation of the dehydration tank (25). Incidentally, the effect can be obtained.
이상에서 설명한 바와 같이, 본 고안에 따르면, 탈수조와 볼평형장치가 강하게 결합되어 볼평형장치가 흔들림이 없이 재 기능을 발휘할 수 있으며, 별도의 회전축고정부의 제작이 필요 없으며, 금속성 재질로 제작되어 볼평형장치의 외형에 변화가 생기지 않는다.As described above, according to the present invention, the dewatering tank and the ball balancer are strongly coupled so that the ball balancer can perform the re-function without shaking, and there is no need to manufacture a separate rotating shaft fixing part and is made of a metallic material. There is no change in the appearance of the ball balancer.
