그리고, 리프터(140)의 분사홀부(164)는 일렬로 나란한 복수개 배열되어 리프터(140)내에 수용된 세탁수는 전구역에 균일하게 분사될 수 있다.
In addition, the plurality of spray holes 164 of the lifter 140 are arranged side by side in a row so that the wash water accommodated in the lifter 140 may be uniformly sprayed in the entire area.

상기와 같은 구조를 갖는 본 발명의 일 실시예에 따른 드럼 세탁기의 작용을 설명하면 다음과 같다.Referring to the operation of the drum washing machine according to an embodiment of the present invention having the structure as described above are as follows.

우선, 드럼(130)의 내측에 착탈부(150)에 의해 장착되는 리프터(140)는 일정 높이로 드럼(130)의 내부로 돌출되어 구비된다.First, the lifter 140 mounted by the detachable part 150 inside the drum 130 is provided to protrude into the drum 130 at a predetermined height.

그리고, 리프터(140)는 만곡되어 형성되므로 내부에 일정 공간을 형성한다.Since the lifter 140 is curved, the lifter 140 forms a predetermined space therein.

이후, 도어(112)를 개방하여 드럼(130)의 내부로 세탁물을 수용시키고, 급수구 박스(115)를 통해 세탁수가 공급되면, 도 4에서 도시된 바와 같이 드럼(130)의 리프터(140)와 터브(120)의 유입구(125)는 일치된 상태이므로 세탁수는 유입구(125)를 통해 리프터(140)로 진입된다.Thereafter, the door 112 is opened to accommodate the laundry in the drum 130, and when the wash water is supplied through the water inlet box 115, the lifter 140 of the drum 130 as shown in FIG. 4. Since the inlet 125 of the tub 120 is in a matched state, the wash water enters the lifter 140 through the inlet 125.

이는 리프터(140)와 대응되게 드럼(130)의 둘레면에 장공부(162)가 형성되어 가능하다. 즉, 장공부(162)를 통해 만곡된 리프터(140)의 내부에 세탁수는 수용되고, 리프터(140)에 형성되는 분사홀부(164)를 통해 세탁수는 세탁물의 상부로 분사된다.This is possible because the long hole 162 is formed on the circumferential surface of the drum 130 to correspond to the lifter 140. That is, the wash water is accommodated in the lifter 140 curved through the long hole 162, and the wash water is sprayed to the upper part of the laundry through the injection hole 164 formed in the lifter 140.

분사홀부(164)에 의해 세탁물의 상부로 분사되는 세탁수에 의해 세탁물은 드럼(130)내에서 부유되지 않고 충분히 적셔질 수 있다.The laundry may be sufficiently wet without being suspended in the drum 130 by the washing water sprayed onto the laundry by the spray hole 164.

리프터(140)와 유입구(125)가 일치되지 않더라도, 유입구(125)를 통해 공급되는 세탁수는 드럼(130)의 외주면을 따라 흐르면서 리프터(140)의 내부공간에 수용되므로 상기와 동일한 작용 이 가능하다.Even if the lifter 140 and the inlet 125 do not match, the washing water supplied through the inlet 125 flows along the outer circumferential surface of the drum 130 and is accommodated in the inner space of the lifter 140, thereby enabling the same operation as described above. Do.

그리고, 세탁물의 세탁을 위해 세탁수가 채워진 드럼(130)이 정, 역회전을 하면서 세탁을 수행하게 되는데, 도 5에서 도시된 바와 같이 드럼(130)의 리프터(140)에 의해 세탁물이 들어올려지고, 이와 동시에 리프터(140)의 내부로 세탁수가 유입되며, 드럼(130)의 회전에 의해 리프터(140)가 상부로 이동되면, 자중에 의해 리프터(140) 내부의 세탁수가 세탁물로 분사되게 된다.Then, the drum 130 filled with the washing water for washing the laundry is performed to perform the washing while the forward, reverse rotation, as shown in Figure 5 the laundry is lifted by the lifter 140 of the drum 130 At the same time, the wash water flows into the lifter 140, and when the lifter 140 is moved upward by the rotation of the drum 130, the wash water inside the lifter 140 is sprayed into the laundry by its own weight.

드럼(130)이 정,역회전 어느 방향으로 회전되더라도 리프터(140)로의 세탁수 유입은 계속해서 이루어지게 되며 이에 따라 세탁물로 계속해서 세탁수가 분사될 수 있다.Even if the drum 130 is rotated in any of the forward and reverse directions, the washing water flows into the lifter 140 continuously. Accordingly, the washing water may be continuously injected into the laundry.

그리고, 리프터(140)의 분사홀부(164)가 일렬로 나란하게 복수개 배치되므로 리프터(140)에 수용된 세탁수는 전구역에 균일하게 분사될 수 있다.In addition, since a plurality of spray holes 164 of the lifter 140 are arranged side by side in a row, the wash water accommodated in the lifter 140 may be uniformly sprayed in the entire area.

상기한 바와 같이 최초 세탁수의 공급에 의해 세탁물의 상부로 세탁수를 분사할 수 있어 세탁물을 충분히 적실 수 있고, 세탁과정에서 세탁수를 리프터에 의해 퍼올려 세탁물에 분사할 수 있으므로 세제용해의 활성화 및 세탁력향상의 효과를 얻을 수 있다.
As described above, the washing water can be sprayed to the upper part of the laundry by the supply of the initial washing water, so that the laundry can be sufficiently wetted, and the washing water can be sprayed by the lifter and sprayed on the laundry during the washing process to activate detergent dissolution. And an improvement in washing power.
