본 발명은 세탁기의 포꼬임 방지를 위한 2층구조의 펄세이터에 관한 것으로, 특히 상부덮개에 유로가이드를 일체로 형성하여 세탁시 실밥채집기능을 수행가능하도록 한 세탁기의 포꼬임 방지를 위한 2층구조의 펄세이터에 관한 것이다.The present invention relates to a two-layer pulsator for preventing poking of a washing machine, and in particular, a two-layer for preventing poking of a washing machine that is capable of performing a sewing function during washing by integrally forming a flow guide in an upper cover. It relates to a structure pulsator.

일반적인 세탁기의 펄세이터는 모터와 감속기에 의해서 좌,우로 반전되면서 세탁물을 흔들거나 내조에 부딪히게 하여 세탁을 실시하도록 하고 있는 바, 이러한 종래의 펄세이터에 의한 세탁은 세탁물(洗濯物)을 세탁수(洗濯水)의 수류를 강하게 하여 세탁물과 세탁수가 접촉되어 물살의 힘에 의한 세탁을 실시하는 것이므로, 수류의 세기가 강할수록 세탁효과가 향상되는 것이었다.The pulsator of a general washing machine is inverted to the left and right by a motor and a reducer, and the laundry is shaken or bumped into the inner tank to perform the washing. Such a conventional pulsator washes the laundry. Since the water flow of the water was strengthened and the laundry and the water were in contact with each other to wash by the force of water, the stronger the flow of water, the better the washing effect.

그러나, 상기한 바와 같은 종래의 펄세이터를 사용한 세탁기의 세탁은 세탁조 저부에서 회전하는 펄세이터로부터 전달하는 힘을 이용하여 세탁조 내부에 담긴 세탁수를 회전시켜 세탁을 하는 것으로, 세탁수는 원심력에 의하여 세탁조 내부의 가장자리로 밀려나가게 되고, 세탁물은 중앙으로 몰리게 되어 중앙으로 몰린 세탁물이 서로 엉키게 됨으로써 세탁효과가 균일하게 이루어지지 않는 문제가 있었다.However, the washing of the washing machine using the conventional pulsator as described above is to wash by rotating the washing water contained in the washing tank by using the force transmitted from the pulsator rotating in the washing tank bottom, the washing water is centrifugal force It is pushed to the edge of the inside of the washing tank, the laundry is driven to the center, the laundry driven in the center is tangled with each other there was a problem that the washing effect is not made uniform.

이러한 문제점을 해소하기 위하여 제1도에 도시한 바와 같은, 2층구조를 갖는 펄세이터가 제공되었는 바, 이는 내조(2) 하부에 설치되고, 중앙에 토출구(3)가 형성되며, 하부에 모터 및 감속기(미도시)와 결합하는 상부날개(4)와, 상기 상부날개(4)의 저면에 결합되어 상부날개(4)와 연통되는 유로(5)가 형성되는 하부날개(6)로 구성되며, 상기 하부날개의 유로(5)에 곡면유로가이드(7)를 설치한 것을 구성으로 하고 있다.In order to solve this problem, a pulsator having a two-layer structure, as shown in FIG. 1, has been provided, which is installed under the inner tank 2, a discharge port 3 is formed in the center, and a motor And a lower wing 6 formed with an upper wing 4 coupled to a speed reducer (not shown), and a flow path 5 connected to the bottom of the upper wing 4 to communicate with the upper wing 4. The curved flow path guide 7 is provided in the flow path 5 of the lower blade.

이와 같은 2층구조의 펄세이터를 구비한 세탁기의 세탁은 모터의 동력을 전달받는 감속기의 작동으로 상부날개(4)가 회전되고, 상부날개(4)의 회전으로 세탁수가 원심력에 의해 내조(2)의 내측면으로 쏠려 외조(1)로 빠져나가게 됨과 동시에 내조(2)와 외조(1) 사이의 하부에 위치한 세탁수가 하부날개의 유로(5)와 곡면유로가이드(7)를 통하여 상부날개의 토출구(3)로 공급되어 상부날개의 중앙부에서 상측으로 분출되면서 세탁물의 꼬임을 방지하게 된다.In the washing of the washing machine having the pulsator having the two-layer structure as described above, the upper blade 4 is rotated by the operation of the speed reducer receiving the power of the motor, and the washing water is rotated by the centrifugal force by the rotation of the upper blade 4. At the same time, the washing water located at the lower side between the inner tank (2) and the outer tank (1) is pulled toward the inner side of the outer tank (1) and at the same time through the lower wing passage (5) and the curved flow guide (7). It is supplied to the discharge port (3) is ejected to the upper side from the center of the upper blade to prevent the twist of the laundry.

그러나, 상기한 바와 같은 종래 2층구조의 펄세이터는 도시한 바에서와 같이, 곡면유로가이드(7) 그 자체를 엷은 고무판과 같은 누수방지 가스켓으로 형성하였기 때문에 상부날개의 토출구로 세탁수를 유도하는 유로내에서의 불완전한 실링으로 인해서 그 유로내의 세탁수 전부가 토출구로 유도되지 못하고 그 일부가 곡면유로가이드(7) 틈새로 새어나감으로써 상부날개의 토출구로 분출되는 수압이 저하되는 문제가 있다.However, the pulsator of the conventional two-layer structure as described above, as shown in the drawing, guides the wash water to the discharge port of the upper blade because the curved flow guide 7 itself is formed of a leak-proof gasket such as a thin rubber plate. Due to the incomplete sealing in the flow path, all of the wash water in the flow path is not guided to the discharge port, and a part of the water leaks into the discharge port of the upper blade by leaking into the gap of the curved flow path guide 7, thereby causing a problem.

또한, 이러한 펄세이터의 구조에 의하면 실밥채집용 터널(2a)의 입구측이 상기한 곡면유로가이드(7)에 의해 가로막혀 있게 되므로 하부날개(6)에 의하여 유입된 세탁수가 직접 실밥채집용 터널(2a)로 안내되지 못하게 되므로 실질적인 실밥채집기능을 수행하지 못하는 문제가 있다.In addition, according to the structure of the pulsator, since the inlet side of the seams collecting tunnel (2a) is blocked by the curved flow guide (7) described above, the wash water introduced by the lower wing (6) is a direct seams collecting tunnel. Since it is not guided to (2a) there is a problem that can not perform a practical seams collecting function.

이와 같은 문제점에 착안하여 안출한 본 발명의 목적은 펄세이터의 상부날개로 공급되는 유로가이드의 실링력을 완전하도록 하여 상부날개의 중앙에서 분출되는 물기둥의 수입을 증대시켜 세탁물의 꼬임방지기능을 향상시키도록 한 세탁기의 포꼬임 방지를 위한 2층구조의 펄세이터를 제공함에 있다.The object of the present invention devised in view of the above problems is to complete the sealing force of the flow path guide supplied to the upper blade of the pulsator to increase the import of the water column ejected from the center of the upper blade to improve the anti-twist function of the laundry It is to provide a two-layer pulsator for preventing poking of the washing machine.
