Abstract

본 발명은 세탁기의 2중펄세이터에 관한 것으로, 종래 기술에 의한 2중펄세이터의 분출수류가 상, 하부펄세이터 사이의 상부유로에서 발생되는 표면저항원심력에 의해 약해지는 문제점을 해결하기 위한 것이다. 본 발명은 세탁기 내조(12)의 장착홈(13)에 장착되어 세탁기의 회전축(14)에 끼워진 하부 펄세이터(50)의 상면에는 다수개의 지지부(51, 51')가 형성되고 하면에는 다수개의 회전날개(52)가 방사상으로 형성되며, 상기 하부펄세이터(50)와 함께 회전하는 상부펄세이터(40)의 하면은 상기 지지부(51, 51')에 결합되고, 상기 상, 하부펄세이터(50, 40)의 사이에 형성되는 상부유로(41)의 상하면에는 다수개의 돌부(40', 50')를 형성하여서 구성되며, 상기 돌부(40', 50')는 하부펄세이터(50)의 상면과 상부펄세이터(40)의 하면에 회전축(14)과 동심상으로 형성된 원형리브임을 특징으로 한다. 상기와 같은 본 발명에 의한 세탁기의 2중펄세이터에 의하면 내조의 중앙으로 강력한 물기둥을 형성할 수 있어 세탁물의 엉킴을 방지하고 세탁효과를 높일 수 있는 이점이 있다.The present invention relates to a double pulsator of a washing machine, to solve the problem that the jet flow of the double pulsator according to the prior art is weakened by the surface resistance centrifugal force generated in the upper flow path between the upper and lower pulsator. . According to the present invention, a plurality of support parts 51 and 51 ′ are formed on an upper surface of a lower pulsator 50 fitted to the mounting groove 13 of the washing machine inner tank 12 and fitted to the rotating shaft 14 of the washing machine. The rotary blade 52 is formed radially, the lower surface of the upper pulsator 40 that rotates with the lower pulsator 50 is coupled to the support (51, 51 '), the upper, lower pulsator ( The upper and lower surfaces of the upper flow passage 41 formed between 50 and 40 are formed by forming a plurality of protrusions 40 'and 50', and the protrusions 40 'and 50' are formed of the lower pulsator 50. The upper surface and the lower surface of the upper pulsator 40 is characterized in that the circular rib formed concentrically with the rotating shaft (14). According to the double pulsator of the washing machine according to the present invention as described above can form a strong water column in the center of the inner tank has the advantage of preventing the tangling of the laundry and increase the washing effect.
