상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

도 5a 내지 도 5c는 본 발명에 따른 드럼세탁기의 세탁 또는 헹굼시 상태가 도시된 단면도이다.5a to 5c is a cross-sectional view showing a state when washing or rinsing the drum washing machine according to the present invention.

먼저, 세탁기가 작동되면, 포량이 감지되어 상기 터브(54)와 드럼(56) 내부로 설정된 수위까지 세탁수가 공급된 다음, 상기 모터(58)가 작동됨에 따라 상기 드럼(56)이 정방향(P) 또는 역방향(Q)으로 회전되면서 세탁 및 헹굼 행정이 수행된다.First, when the washing machine is operated, the quantity of water is sensed and the washing water is supplied to the water level set inside the tub 54 and the drum 56. Then, as the motor 58 is operated, the drum 56 moves in the forward direction (P). Washing or rinsing stroke is performed while rotating in the reverse direction Q).

여기서, 상기 드럼(56)이 회전됨에 따라 상기 드럼(56) 내벽에 고정 설치된 리프트(70)도 같이 회전되면서 상기 드럼(56)의 하측에 위치된 세탁물이 상기 리프트(70)에 걸림되어 원주 방향을 따라 일정 높이 이상 이동된 다음, 상기 드럼(56)의 하측으로 떨어지면서 낙차에 의해 충격력과 굴신에 의해 세탁 및 헹굼이 수행된다.Here, as the drum 56 is rotated, the lift 70 fixed to the inner wall of the drum 56 is also rotated, and the laundry located below the drum 56 is caught by the lift 70 and circumferentially. After moving above a certain height, and falling down the drum 56, washing and rinsing are performed by impact force and flexion by dropping.

이때, 상기 드럼(56)이 정방향(P)으로 회전될 경우, 상기 리프트(70)는 상기 좌측 경사면(72)과 제1격벽(79a) 사이에 홈 형상의 세탁수 저장부가 형성되기 때문에 도 5a 내지 도 5c에 도시된 바와 같이 상기 드럼(56)이 회전됨에 따라 상기 좌측 경사면(72)과 제1격벽(79a) 사이에 세탁수가 담아지게 되고, 그 세탁수는 일정 높이에서 떨어지게 된다.At this time, when the drum 56 is rotated in the forward direction (P), since the lift 70 is formed in the groove-shaped wash water storage portion between the left inclined surface 72 and the first partition (79a) Figure 5a As shown in FIG. 5C, as the drum 56 is rotated, washing water is contained between the left inclined surface 72 and the first partition wall 79a, and the washing water falls at a predetermined height.

물론, 상기 드럼(56)이 역방향(Q)으로 회전될 경우, 상기 리프트(70)는 역시 상기 우측 경사면(74)과 제2격벽(79b) 사이에 홈 형상의 세탁수 저장부가 형성되기때문에 상기 드럼(56)이 회전됨에 따라 상기 우측 경사면(74)과 제2격벽(79b) 사이에 세탁수가 담아져 일정 높이에서 떨어지게 된다.Of course, when the drum 56 is rotated in the reverse direction (Q), because the lift 70 is also formed in the groove-shaped wash water storage portion between the right inclined surface 74 and the second partition wall (79b) As the drum 56 is rotated, the wash water is contained between the right inclined surface 74 and the second partition wall 79b to fall from a predetermined height.

따라서, 상기 드럼(56)이 회전됨에 따라 상기 리프트(70)에 의해 세탁수가 일정 높이에서 떨어져 세탁물이 부딪히도록 하여 두드려 빠는 효과를 높일 수 있고, 세탁수를 상기 드럼(56)의 원주 방향으로 유동시킬 뿐 아니라 상기 드럼(56)의 수직 방향으로 유동시킴으로 다양한 세탁 수류를 형성하여 비벼빠는 효과를 높일 수 있으므로 세탁 및 헹굼 성능을 높일 수 있다.Therefore, as the drum 56 is rotated, the washing water is dropped by a certain height by the lift 70 so that the laundry collides with the laundry, thereby increasing the effect of tapping and washing the water in the circumferential direction of the drum 56. In addition to the flow of the drum 56 in the vertical direction of the flow by forming a variety of washing water flow can increase the effect of rubbing can increase the washing and rinsing performance.

상기와 같이 구성되는 본 발명에 따른 드럼세탁기의 리프트는 오목하게 형성된 좌,우측 경사면과, 상기 좌,우측 경사면의 전,후단에 수직하게 각각 형성된 제1,2격벽으로 이루어져 상기 좌측 경사면과 제1격벽 또는 상기 우측 경사면과 제2격벽 사이에 세탁수가 담겨질 수 있도록 세탁수 저장부가 형성되기 때문에 상기 드럼이 회전됨에 따라 상기 리프트에 세탁수가 담겨져 일정 높이에서 떨어지도록 하여 두드려빠는 효과를 높일 뿐 아니라 상기 드럼의 원주 방향 및 수직 방향으로 세탁수가 유동되도록 하여 다양한 세탁 수류를 형성하여 비벼 빠는 효과를 높일 수 있으므로 세탁 및 헹굼 성능을 높일 수 이점이 있다.The lift of the drum washing machine according to the present invention configured as described above comprises a left and a right inclined surface formed in a concave shape, and first and second bulkheads formed perpendicularly to the front and rear ends of the left and right inclined surfaces, respectively. Since the wash water storage unit is formed to hold the wash water between the partition wall or the right inclined surface and the second partition wall, as the drum is rotated, the wash water is contained in the lift so that the wash water falls from a certain height, thereby enhancing the tapping effect. Since the washing water flows in the circumferential direction and the vertical direction of the various washing streams to increase the effect of scrubbing, there is an advantage to increase the washing and rinsing performance.
