여기서, 본 발명의 일 실시예에 따른 드럼세탁기용 드럼은 리프터(72)에 의해 상승되는 세탁물이 낙하되면서 충돌되는 볼록부(76)와, 볼록부(76)와 교호로 배치되는 오목부(78)를 포함한다.Here, the drum for a drum washing machine according to an embodiment of the present invention is a convex portion 76 and collision concave portion 76 alternately arranged with the convex portion 76 collided while the laundry lifted by the lifter 72 falls. ).

드럼(70)에 세탁물이 수납된 후에 세탁작동이 개시되며 리프터(72)에 의해 드럼(70) 내부에서 상측 방향으로 상승된 세탁물은 드럼(70)의 하측 방향으로 낙하하게 되는데, 회전 중인 드럼(70)의 볼록부(76)에 충돌되면서 세탁물이 두드려지는 작용이 발생된다.After the laundry is stored in the drum 70, the washing operation is started, and the laundry lifted upward in the drum 70 by the lifter 72 falls in the downward direction of the drum 70. The impact of the laundry on the convex portion 76 of the 70 tapping occurs.

세탁물이 회전 중인 드럼(70)의 내벽에 충돌되면 짧은 시간 내에 다수 개의 볼록부(76)와 연속적으로 충돌되므로 세탁물을 두드리는 작용이 다수 차례 발생된다.When the laundry collides with the inner wall of the rotating drum 70, a plurality of convex portions 76 are continuously collided with each other in a short time, so that the laundry is knocked.

또한, 세탁물이 드럼(70) 내벽에 충돌된 후에도 드럼(70)은 계속 회전되므로 세탁물이 드럼(70) 내벽을 따라 소정량 슬라이딩되면서 세탁물을 빨래판에 비비는 것과 같은 작용이 발생된다.In addition, since the drum 70 continues to rotate even after the laundry impinges on the inner wall of the drum 70, the laundry 70 slides a predetermined amount along the inner wall of the drum 70 to rub the laundry onto the washboard.

상기한 바와 같은 작동은 드럼(70)의 내측 방향으로 돌출되는 볼록부(76)와 드럼(70)의 외측 방향으로 돌출되는 오목부(78)가 교호로 연속되고 드럼(70) 내벽 전체에 걸쳐 형성되기 때문에 발생될 수 있게 된다.As described above, the convex portion 76 protruding in the inward direction of the drum 70 and the concave portion 78 protruding in the outward direction of the drum 70 are alternately continuous, and the entire inner wall of the drum 70 is extended. It can be generated because it is formed.

또한, 드럼(70)의 내벽에는 리프터(72)가 설치되는 평면부(79)가 구비되고, 볼록부(76) 또는 오목부(78)가 형성되지 않는 평면부(79)에 리프터(72)가 설치되기 때문에 리프터(72)의 단부 형상이 직선으로 형성되어도 리프터(72)의 장착을 용이하게 행할 수 있게 된다.In addition, the inner wall of the drum 70 is provided with a flat portion 79 on which a lifter 72 is provided, and a lifter 72 on a flat portion 79 on which no convex portion 76 or concave portion 78 is formed. Since is provided, even if the end shape of the lifter 72 is formed in a straight line, the lifter 72 can be easily mounted.

여기서, 평면부(79)는 다수개 구비되고, 평면부(79) 사이의 형성되는 각도가 동일하게 배치되므로 평면부(79)에 설치되는 리프터(72)에 의해 드럼(70)이 편심되는 것을 방지하여 안정된 회전을 행할 수 있도록 한다.Here, the plane portion 79 is provided with a plurality, and since the angle formed between the plane portion 79 is arranged the same that the drum 70 is eccentric by the lifter 72 installed in the plane portion 79 Prevent stable rotation.

볼록부(76)와 오목부(78)는 드럼(70)의 회전축과 동일한 방향으로 배치되므로 리프터(72)에 의해 회전되는 세탁물의 운동 방향과 볼록부(76)의 방향이 직교하게 되어 세탁물이 드럼(70) 내벽을 따라 슬라이딩될 때에 볼록부(76)에 의해 세탁물이 비벼지는 효과가 향상되도록 한다.Since the convex portion 76 and the concave portion 78 are disposed in the same direction as the rotation axis of the drum 70, the direction of movement of the laundry rotated by the lifter 72 and the direction of the convex portion 76 are perpendicular to each other. The sliding effect of the laundry by the convex portion 76 when the drum 70 slides along the inner wall is improved.

물론, 볼록부(76) 및 오목부(78)가 드럼(70)의 회전축과 소정 각도 이격되게 배치되어 경사진 모양으로 형성되어도 무방하며, 볼록부(76)가 드럼(70)의 회전축과 소정 각도 이격되게 형성되면 드럼(70) 내벽을 따라 형성되는 스크루 모양을 이루게 되므로 세탁물의 유동을 증가시키게 된다.Of course, the convex portion 76 and the concave portion 78 may be disposed to be inclined to be spaced apart from the rotational axis of the drum 70 by a predetermined angle, and the convex portion 76 may have a predetermined rotational axis with the rotational axis of the drum 70. When formed at an angular distance to form a screw formed along the inner wall of the drum 70 increases the flow of the laundry.

이렇게 볼록부(76)가 경사지게 형성되는 다른 실시예는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 구체적인 도면이나 설명은 생략하기로 한다.Thus, another embodiment in which the convex portion 76 is formed to be inclined may be easily changed and implemented by those skilled in the art who have recognized the technical configuration of the present invention, and thus detailed drawings and descriptions thereof will be omitted.

이때, 드럼(70)이 회전되면 리프터(72)에 의해 상승된 세탁물이 낙하되면서 볼록부(76) 및 다른 리프터(72)와 충돌되면서 세탁물을 두드리는 작용이 발생되어 세탁작동이 이루어지게 된다.At this time, when the drum 70 is rotated, the laundry lifted by the lifter 72 falls and collides with the convex portion 76 and the other lifter 72 to knock the laundry, thereby causing the washing operation.

특히, 볼록부(76)에 세탁물이 충돌될 때에는 드럼(70)이 회전되고 있는 상태에서 세탁물의 충돌이 이루어지게 되므로 짧은 시간 내에 다수 개의 볼록부(76)와 세탁물이 연속하여 충돌하게 되어 세탁물을 두드리는 작용이 증가하게 된다.In particular, when the laundry collides with the convex portion 76, the laundry is collided while the drum 70 is being rotated, so that the plurality of convex portions 76 and the laundry continuously collide with each other within a short time so that the laundry may be separated. Tapping will increase.

또한, 볼록부(76)에 충돌된 세탁물은 드럼(70)의 회전에 의해 드럼(70) 내벽을 따라 소정량 슬라이딩되는데, 이때, 연속되게 배치되는 볼록부(76)에 의해 세탁 물을 빨래판에 비비는 것과 같은 효과가 나타나게 된다.In addition, the laundry impinging on the convex portion 76 is slid by a predetermined amount along the inner wall of the drum 70 by the rotation of the drum 70, at this time, by the convex portion 76 arranged in succession to the laundry plate You will get the same effect as rubbing.

볼록부(76) 또는 오목부(78)에는 홀부(74)가 형성되어 터브(60)에 담수되는 세탁수가 드럼(70) 내측으로 공급되고, 드럼(70)이 회전될 때에 세탁수가 드럼(70) 외측으로 순환되며, 탈수작동을 행할 때에는 이 홀부(74)를 통해 세탁수가 배출되면서 세탁물로부터 세탁수를 분리시키게 된다.Holes 74 are formed in the convex portion 76 or the concave portion 78 to wash the fresh water in the tub 60 into the drum 70, and when the drum 70 is rotated, the wash water is in the drum 70. Circulated to the outside and wash water is discharged through the hole 74 to separate the wash water from the laundry.

필요에 따라 홀부(74)를 오목부(78)에만 배치시켜도 무방하며, 이는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있으므로 구체적인 도면이나 설명은 생략하기로 한다.If necessary, the hole portion 74 may be disposed only in the recess portion 78, which can be easily changed and implemented by those skilled in the art who have recognized the technical configuration of the present invention.
