도 1을 참조하면, 본 발명의 일실시예에 따른 드럼 세탁기의 드럼(100)은, 드럼부(110)와 리프트부(120)를 포함하며, 드럼부(110)와 리프트부(120)가 하나의 부재(10)(도 2 참조)에 의해 일체로 연결형성된 구조를 가진다.Referring to FIG. 1, the drum 100 of a drum washing machine according to an embodiment of the present invention includes a drum part 110 and a lift part 120, and the drum part 110 and the lift part 120 are provided. It has a structure integrally connected by one member 10 (see FIG. 2).

드럼부(110)는 판상형의 부재(10)를 원형으로 권취하여 형성되며, 내부에 세탁물을 수용, 저장한 상태로 회전가능한 원통형상을 가진다.The drum unit 110 is formed by winding the plate-shaped member 10 in a circular shape, and has a cylindrical shape rotatable in a state of storing and storing laundry therein.

리프트부(120)는 부재(10)의 일부가 일측으로 볼록하게(돌출되게) 굴곡되어 형성되며, 부재(10)의 권취에 의해 드럼부(110)의 내부에 내향 돌출되게 위치된다.The lift part 120 is formed by bending a part of the member 10 to be convex (protruded) to one side, and is positioned to protrude inwardly into the drum part 110 by winding the member 10.

리프트부(120)는 본 발명에 따른 드럼 세탁기의 드럼(100)의 회전 시, 세탁물과 세탁수를 드럼부(110)의 상측으로 받쳐 들어올릴 수 있는 돌출높이를 가진다.The lift unit 120 has a protrusion height capable of supporting the laundry and the washing water to the upper side of the drum unit 110 when the drum 100 of the drum washing machine according to the present invention is rotated.

본 발명의 일실시예에서 리프트부(120)는 도어(20)에 인접한 드럼부(110)의 일측부에서 도어(20)로부터 이격되는 타측부까지 연장되게 형성되고, 복수개가 드럼부(110)의 원주방향을 따라 상호 이격되게 배치된다.In one embodiment of the present invention, the lift unit 120 is formed to extend from one side of the drum unit 110 adjacent to the door 20 to the other side spaced apart from the door 20, a plurality of the drum unit 110 Are spaced apart from each other along the circumferential direction of.

이에 따라, 리프트부(120)가 드럼부(110) 내부에 수용된 세탁물을 드럼부(110)의 일측부에서 타측부 전체에 걸쳐 균일하게 리프팅시키며 낙차를 가할 수 있다.Accordingly, the lift unit 120 may apply a drop while uniformly lifting the laundry accommodated in the drum unit 110 from the one side of the drum unit 110 to the whole of the other side.

리프트부(120) 복수개가 이격 형성됨에 따라, 드럼부(110) 내부의 세탁물이 드럼부(110)의 원주방향의 일측에 편중되지 않고 리프트부(120) 각각에 의해 구획되는 복수개의 영역에 걸쳐 균일하게 위치하게 된다.As the plurality of lift units 120 are spaced apart, the laundry inside the drum unit 110 is not biased to one side in the circumferential direction of the drum unit 110, but is spread over a plurality of areas partitioned by each of the lift units 120. It is evenly located.

특히, 본 발명의 일실시예에 따른 리프트부(120)는, 드럼부(110) 내부로 돌출된 돌출단부(121)가 타측부로 갈수록 너비가 축소되며 삼각형 형상을 이루는 구조를 가진다.In particular, the lift unit 120 according to an embodiment of the present invention has a structure in which the protruding end portion 121 protruding into the drum unit 110 decreases in width toward the other side and forms a triangular shape.

즉, 돌출단부(121)의 일측부는 너비가 확장형성되고, 타측부는 너비가 축소형성된 구조를 가진다.That is, one side of the protruding end 121 has an expanded width, and the other side has a structure in which the width is reduced.

상기와 같은 형상에 의해 돌출단부(121)의 너비를 확보할 수 있으면서도, 리프트부(120)를 입체적인 형상을 이루는 부분 중 모서리부의 갯수를 저감시킬 수 있다.While the width of the protruding end portion 121 can be secured by the shape as described above, the number of the corner portions among the portions forming the three-dimensional shape of the lift portion 120 can be reduced.

돌출단부(121)의 너비(드럼부(110)의 원주방향)를 확보하면, 리프트부(120)의 일측부에 너비방향으로 가압력이 작용하더라도 원거리에 위치되는 타측부까지 가압력이 전달되는 과정에서 분산되며 원거리까지 전달될 수 있다.When the width of the protruding end 121 (the circumferential direction of the drum 110) is secured, even if the pressing force is applied to one side of the lift unit 120 in the width direction, the pressing force is transmitted to the other side located at a distance. It is distributed and can be transmitted over long distances.

즉, 돌출단부(121)의 너비(드럼부(110)의 원주방향)를 확보하면, 리프트부(120)에 작용하는 가압력을 보다 확장된 영역에 걸쳐 고르게 분산하여 지지할 수 있어, 리프트부(120)의 너비방향으로의 강도를 보강할 수 있다.That is, if the width (circumferential direction of the drum part 110) of the protruding end portion 121 is secured, the pressing force acting on the lift part 120 can be evenly distributed and supported over the extended area, thereby providing a lift part ( 120), the strength in the width direction can be reinforced.

이에 따라, 리프트부(120)가 드럼부(110)의 하단으로부터 90°에 대응되는 위치까지 상향 이동되는 과정에서 상하방향으로 작용하는 세탁물의 중량에 의한 휘어짐을 안정적으로 방지할 수 있다.Accordingly, it is possible to stably prevent the lift unit 120 from bending due to the weight of the laundry acting in the vertical direction in the process of moving upward from the lower end of the drum unit 110 to a position corresponding to 90 °.

또한, 모서리부의 갯수를 저감시킴으로써 부재(10)의 굴곡 가공에 의해 특히 응력이 집중하여 잔류하게 되는 영역을 줄임으로써, 잔류응력에 의한 강도 저하를 보완할 수 있다.In addition, by reducing the number of corners, the reduction in strength due to residual stress can be compensated for by reducing the area where stress is concentrated due to the bending of the member 10.

Only after passing the drum combined with the lift was possible to discharge the drum out of the wash water.

이러한 과정에서 리프트 내부에 오염된 세탁수가 정체되기도 하여, 세탁, 헹굼, 배수 과정에서 오염된 잔수 등으로 인해 세탁성능이 저하되었다.In this process, the contaminated washing water is stagnated in the lift, and the washing performance is degraded due to the contaminated residual water during washing, rinsing, and draining.

본 발명의 일실시예에 의하면 드럼부(110)와 리프트부(120)가 하나의 판상형 부재(10)에 의해 일체로 연결형성된 구조를 가짐에 따라, 세탁수를 정체시키게 되는 기존의 드럼과 리프트 사이의 유격, 리프트 내부 공간부를 제거할 수 있다.According to an embodiment of the present invention, as the drum 110 and the lift unit 120 have a structure in which the plate member 10 is integrally formed and connected, the existing drum and the lift to stagnate the washing water. The clearance between the lift and the space inside the lift can be removed.

이에 따라, 리프트부(120)상에 형성된 개방홀부(113)를 통한 세탁수의 유입, 배출이 정체없이 원활하게 이루어질 수 있으며, 오염된 잔수의 드럼 내 잔류 가능성을 배제함으로써 세탁성능을 보다 향상시킬 수 있다.Accordingly, the inflow and discharge of the wash water through the open hole 113 formed on the lift part 120 can be made smoothly without congestion, and the washing performance can be further improved by excluding the possibility of contaminant residue remaining in the drum. Can be.
