The drum type washing machine and the pulsator type washing machine which wash | cleans by the formation of the water flow which generate | occur | produced in the process of rotating the pulsator inside a washing tank while rotating the washing tank vertically from the ground are known.

도 1은 세탁 및 탈수가 하나의 수조에서 이루어지는 1조식 펄세이터방식의 일례를 도시한 단면 구조도로서, 이와 같은 펄세이터 방식의 세탁기(200)는 세탁물이 저장되는 세탁조(150)의 외부에 저수조(160)가 결합됨으로써 세탁에 필요한 물을 세탁조(150)로 공급하는 한편, 탈수시에는 세탁조(150)로부터 배출된 세탁수의 배출경로를 제공한다.1 is a cross-sectional structural view showing an example of a one-type pulsator type washing and dehydration in a single tank, such a pulsator type washing machine 200 is a water tank (outside the washing tank 150 in which the laundry is stored) 160 is coupled to supply the water necessary for washing to the washing tank 150, while providing a discharge path of the washing water discharged from the washing tank 150 during dehydration.

계속해서 상기한 저수조(160)의 외주면 일측에는 저수조(160)의 만수위 상부와 연통되는 오버 플로우유로(145)가 형성되며, 세탁조(150)의 저부에는 모터(F)의 회전력을 전달받아 회전함으로써 세탁수에 수류를 형성시키는 펄세이터(110)가 결합된다.Subsequently, an overflow passage 145 is formed at one side of the outer circumferential surface of the water tank 160 to communicate with the upper water level of the water tank 160, and the bottom of the washing tank 150 is rotated by receiving the rotational force of the motor F. Pulsator 110 is combined to form a water flow in the wash water.

상기한 펄세이터(110)는 통상적으로 원반형상으로 이루어진 몸체의 상부에 날개차를 방사상으로 돌출시킨 구조로 이루어진 것으로, 이와 같은 펄세이터(110)는 정역회전하는 과정에서 세탁수내에 수류를 형성시키는 동시에 수류의 일부가 오버 플로우유로(145)를 경유하여 세탁조(150)로 토출되는 과정에서 발생한 낙차에너지에 의해 세탁이 이루어지도록 하며, 이와 함께 필터(F)에 의해 세탁수중의 이물질을 포집한다.The pulsator 110 is formed of a structure in which a vane radially protrudes on an upper portion of a body having a disk shape, and such a pulsator 110 forms a stream of water in the wash water in the course of forward and reverse rotation. At the same time, a part of the water stream is washed by the free fall energy generated in the process of being discharged to the washing tank 150 via the overflow passage 145, and the foreign matter in the washing water is collected by the filter F.
