Description

드럼세탁기{DRUM TYPE WASHING MACHINE}Drum Washing Machine {DRUM TYPE WASHING MACHINE}

본 발명은 드럼세탁기에 관한 것으로, 더욱 상세하게는 회전조 내에 설치된 리프터의 개선을 통해 세탁력이 향상될 수 있도록 한 드럼세탁기에 관한 것이다.The present invention relates to a drum washing machine, and more particularly to a drum washing machine to improve the washing power through the improvement of the lifter installed in the rotary bath.

일반적으로 드럼세탁기는 회전조가 회전할 때 생기는 세탁물 및 세탁수의 낙차를 이용하여 세탁물을 세탁하는 장치이다. 이러한 드럼세탁기는 도 1에 도시된 바와 같이, 세탁수의 담수를 위해 본체(1)의 내부에 설치되는 원통형의 고정조(2)와, 고정조(2)의 내부에 회전 가능하게 설치된 회전조(3)를 구비한다.In general, the drum washing machine is a device for washing laundry using a drop of laundry and washing water generated when the rotating tub rotates. As shown in FIG. 1, the drum washing machine includes a cylindrical fixing tub 2 installed inside the main body 1 for fresh water of washing water, and a rotating tub rotatably installed inside the fixing tub 2. (3) is provided.

고정조(2)는 진동과 충격방지를 위해 상부의 현가장치(4)와 하부의 완충장치(5)를 통해 본체(1)의 내부에 지지된다. 그리고 회전조(3)는 회전축(3a)을 통해 고정조(2) 내에 회전 가능하게 설치되며 고정조(2)의 하부에 장착된 구동모터(6)의 동작에 의해 회전한다. 또 드럼세탁기의 회전조(3) 내면에는 회전조(3)가 회전을 할 때 세탁물 및 세탁수를 상부로 끌어올려 낙하시킬 수 있도록 복수의 리프터(7)가 설치되어 있다.The fixing tank 2 is supported inside the main body 1 through the upper suspension 4 and the lower shock absorber 5 to prevent vibration and shock. The rotating tub 3 is rotatably installed in the fixed tub 2 through the rotating shaft 3a and rotates by the operation of the driving motor 6 mounted below the fixed tub 2. In addition, a plurality of lifters 7 are provided on the inner surface of the rotating tub 3 of the drum washing machine so that the laundry and the washing water can be pulled up and dropped when the rotating tub 3 rotates.

이러한 드럼세탁기의 세탁동작은 구동모터(6)의 동작에 의해 회전조(3)가 회전할 때 회전조(3) 내부의 세탁물과 세탁수가 상승되어 자유낙하 되는 동작이 반복되면서 이루어진다. 이때 회전조(3) 내면의 리프터(7)는 회전조(3)가 회전할 때 세탁물이 걸려서 상승되도록 한다.The washing operation of the drum washing machine is performed by repeating an operation in which the laundry and the washing water inside the rotating tub 3 are freely dropped when the rotating tub 3 rotates by the operation of the driving motor 6. At this time, the lifter 7 of the inner surface of the rotating tub 3 allows the laundry to be caught and lifted when the rotating tub 3 rotates.

그런데 이러한 구성의 종래 드럼세탁기는 회전조(3) 내의 리프터(7)에 의한 세탁물 및 세탁수의 상승 낙하동작에 의해서만 세탁을 수행하기 때문에 세탁력을 상승시키는데 한계가 있어 일반적인 펄세이터형 세탁기에 비해 세탁력이 떨어지는 결점이 있었다.However, the conventional drum washing machine having such a configuration has a limit to increase the washing force because washing is performed only by the rising and falling operations of the laundry and the washing water by the lifter 7 in the rotary tub 3, and thus the washing force is higher than that of a general pulsator type washing machine. There was a falling flaw.

본 발명은 이와 같은 문제점을 감안하여 안출된 것으로, 본 발명의 목적은 회전조 내의 리프터가 회전할 때 세탁수에 와류가 생성되도록 함으로써 세탁력 및 헹굼력이 향상될 수 있도록 하는 드럼세탁기를 제공하는 것이다.The present invention has been made in view of the above problems, and an object of the present invention is to provide a drum washing machine that can improve the washing and rinsing power by allowing the vortex to be generated in the wash water when the lifter in the rotating tub rotates. .

A plurality of long lifters 20 are provided.

이때 본 발명에 따른 드럼세탁기의 리프터(20)에는 리프터(20)가 세탁수에잠긴 상태에서 회전할 때 세탁수의 와류를 발생시킴으로써 세탁력 및 헹굼력이 향상될 수 있도록 리프터(20)의 양면을 관통하는 다수의 수류생성공(30)이 마련된다.At this time, the lifter 20 of the drum washing machine according to the present invention has both sides of the lifter 20 so that the washing force and the rinsing force can be improved by generating a vortex of the wash water when the lifter 20 rotates in the wash water. A plurality of water flow generating holes 30 are provided therethrough.

도 3과 도 4는 본 발명에 따른 수류생성공의 제1실시 예를 도시한 것이다. 제1실시 예의 수류생성공(30)은 어느 일단으로부터 그 내경이 점차 커지는 원뿔형으로 마련된다. 또한 제1실시 예는 상호 인접하는 수류생성공(30)의 입구와 출구의 직경이 다르도록 다수의 수류생성공(30)이 상호 반대방향으로 교호적으로 배치된다.3 and 4 illustrate a first embodiment of the water flow generation hole according to the present invention. The water flow generation hole 30 of the first embodiment is provided in a conical shape whose inner diameter gradually increases from one end. In addition, in the first embodiment, a plurality of water flow generating holes 30 are alternately arranged in opposite directions so that diameters of the inlet and the outlet of adjacent water generating holes 30 are different from each other.

이러한 구성은 도 4에 도시된 바와 같이, 리프터(20)가 세탁수에 잠긴 상태에서 어느 일 방향으로 회전할 때 상호 반대로 배치된 각 수류생성공(30)을 통과하는 세탁수의 속도차에 의해 리프터(20)의 후방에서 와류가 생성되도록 한 것이다. 즉 리프터(20)가 화살표 A방향으로 회전할 때 입구가 크고 출구가 작은 상측 수류생성공(30)으로 유입된 세탁수는 리프터(20)의 후방 쪽으로 빠른 속도로 분출되는 반면, 입구가 작고 출구가 큰 하측 수류생성공(30)으로 유입된 세탁수는 느린 속도로 분출된다. 따라서 상호 인접하는 수류생성공(30)을 통과한 세탁수의 속도차에 의해 리프터(20) 후방에서 와류가 생기고, 이러한 와류에 의해 세탁물의 세탁력 및 헹굼력이 향상된다.This configuration, as shown in Figure 4, by the speed difference of the washing water passing through each of the water flow generating holes 30 arranged opposite to each other when the lifter 20 rotates in one direction in the state of being immersed in the washing water Vortex is generated at the rear of the lifter 20.
