본 발명은 드럼세탁기에서 수조의 하부에 고여있는 세탁수를 회전드럼에 구비된 워터재킷으로 끌어올려 세탁물을 향하여 낙하시킬 수 있도록 함으로써 세척효과를 향상시킬 수 있도록 한 드럼세탁기의 세탁수 순환장치에 관한 것이다.The present invention relates to a washing machine circulating device of a drum washing machine, which is capable of dropping the washing water held in the lower part of the tank in the drum washing machine to the water jacket provided on the rotating drum to improve the washing effect. will be.

통상적인 드럼세탁기는 드럼의 회전으로 발생하는 낙차에 의해 세탁이 수행되는 것으로, 세탁기의 외관을 형성하는 하우징의 내부에 구비되는 세탁수를 수용하는 고정드럼과, 고정드럼 내에서 정·역회전이 가능하게 설치된 회전드럼과, 고정드럼을 완충하고 지지하는 충격흡수부재를 구비하고 있다.Conventional drum washing machine is a washing performed by the fall caused by the rotation of the drum, the fixed drum for receiving the wash water provided in the housing forming the appearance of the washing machine, and the forward and reverse rotation in the fixed drum It is provided with the rotating drum which was installed as possible, and the shock absorption member which buffers and supports a fixed drum.

드럼세탁기는 사전에 입력된 프로그램에 따라 회전드럼이 회전하면서 세탁과 헹굼 및 탈수가 자동적으로 이루어지며 세탁하고자 하는 세탁물에 따라 찌든 세탁, 표준세탁, 울세탁 등으로 구분하여 세탁할 수 있게 되어있다.The drum washing machine automatically washes, rinses and dehydrates as the rotating drum rotates according to a previously input program. The drum washing machine can be divided into laundered laundry, standard washing and wool washing according to the laundry to be washed.

그러나 통상적인 드럼세탁기와 같이 드럼의 회전에 의한 낙차만으로 세탁작 업을 행할 경우 세척효율이 충분치 못하므로 고정드럼 내의 세탁수를 끌어올려 세탁물이 있는 회전드럼의 상부에서 낙하시켜 세척력을 향상할 수 있게 하는 구성이 다수 공지된바 있었으며, 그 대표적인 예로 KR등록특허 제757943호(2007.09.05등록)에서는 도 1에 도시된 것과 같이 세탁수가 채워지는 수조(11)와, 수조의 내부에서 회동가능하게 설치된 회전드럼(12)과, 회전드럼의 회전시에 세탁물을 끌어올릴 수 있도록 회전드럼의 내면에 설치된 리프터(40)를 갖추고, 수조와 회전드럼 사이에는 통공을 통해 리프터의 내부로 유입된 세탁수가 회전드럼의 회전시 유출되지 않도록 리프터에 대응되는 회전드럼의 외면에 배치되며 그 중앙에 블레이드 설치공이 형성된 블레이드 커버(51)와, 블레이드 설치공에 결합되는 블레이드(55)를 포함하는 블레이드 유닛이 마련된 것이 공지된바 있었다.However, if the washing operation is performed only by the drop of the drum, as in the conventional drum washing machine, the washing efficiency is not sufficient. Therefore, the washing power in the fixed drum is pulled up and dropped from the upper part of the rotating drum with the laundry to improve the washing power. A number of configurations have been known, and as a representative example of the KR Patent No. 757943 (registered on September 5, 2007), as shown in FIG. Rotating drum 12 and a lifter 40 installed on the inner surface of the rotating drum to lift the laundry during the rotation of the rotating drum, the washing water introduced into the lifter through the through hole between the water tank and the rotating drum rotates Blade cover 51 is disposed on the outer surface of the rotating drum corresponding to the lifter so as not to leak when the drum rotates, the blade installation hole is formed in the center thereof And it was known that the blade unit is provided with a blade 55 coupled to the blade installation hole.

종래의 드럼세탁기에서는 리프터에 의하여 수조의 하부에 고여있는 세탁수를 끌어올려 회전드럼의 상부에서 세탁물을 향하여 세탁수를 낙하하게 하였으나 세탁수를 끌어올리는 리프터의 크기에 제한이 따라 수조에 고여있는 세탁수를 충분히 끌어올리지 못하고, 리프터에 의하여 끌어 올려지는 세탁수가 회전드럼의 정점에 도달하기 전에 리프터의 세탁공(42)에서 유출되어 세탁수가 충분히 세탁물에 도달하지 않아 드럼세탁기의 세척력을 향상시키는데 한계가 있다는 문제점이 있었다.In the conventional drum washing machine, the washing water held in the lower part of the tank is lifted by the lifter to drop the washing water from the upper part of the rotating drum toward the laundry, but the washing in the tank is limited due to the size of the lifter that lifts the washing water. There is a limit to increase the washing power of the drum washing machine because the washing water which is not pulled up sufficiently and is discharged from the washing hole 42 of the lifter before the washing water pulled up by the lifter reaches the peak of the rotating drum and the washing water does not reach the laundry sufficiently. There was a problem.
