본 발명은 세탁기의 펄세이터에 관한 것으로, 특히 세탁물과의 직접마찰을 줄이고, 수직수류를 형성시킬 수 있도록 한 세탁기의 펄세이터에 관한 것이다.The present invention relates to a pulsator of a washing machine, and more particularly, to a pulsator of a washing machine to reduce direct friction with laundry and to form vertical water flow.

일반적으로, 세탁기의 펄세이터는, 세탁조내의 하부에 설치되어 세탁행정시에 좌우반전 회전되어 물 및 세탁물을 회전시킴으로써, 직접적인 세탁작용을 하는 것으로, 종래 세탁기의 펄세이터는 제1도에 도시된 바와 같이 펄세이터 기판(2a)상에 복수개의 날개(2b)가 돌설되어 세탁조(1)의 하부에 회전가능하게 설치된다.In general, the pulsator of the washing machine is installed in the lower part of the washing tank and rotated inverted left and right during the washing operation to rotate the water and the laundry, thereby directly washing the pulsator of the conventional washing machine, as shown in FIG. Likewise, a plurality of vanes 2b protrude from the pulsator substrate 2a and are rotatably installed at the lower part of the washing tank 1.

이와같은 종래 세탁기의 펄세이터에 의하면, 세탁행정시에 그 펄세이터(2)가 좌우반전을 반복하면서 회전되고, 이에따라 펄세이터(2)의 날개(2b)에 의해 물이 밀리면서 회전되어 세탁이 수행된다. 이때 상기 펄세이터(2)가 회전될 때 제2도에 도시된 바와같이 그 펄세이터(2)의 중심부 상부에는 회전수류가 형성되기 때문에 세탁물(3)이 상부에 떠서 회전된다.According to such a pulsator of a conventional washing machine, the pulsator 2 is rotated while repeating the left and right inversion during the washing operation, and accordingly, the water is rotated while the water is pushed by the blades 2b of the pulsator 2 and washing is performed. Is performed. At this time, when the pulsator 2 is rotated, as shown in FIG. 2, since the rotational water flow is formed in the upper portion of the center of the pulsator 2, the laundry 3 floats and rotates.

그런데, 이와같이 종래 펄세이터에 의하면 그 펄세이터(2)의 구조가 기판(2a)위에 날개(2b)가 돌설된 구조이므로, 펄세이터(2)가 회전될 때 그 펄세이터(2) 중심부의 상부에 회전수류가 형성된다. 이 때문에 펄세이터(2)가 회전될때는 세탁물(3)이 아래로 내려오지 못하고 상부에서 회전되므로, 세탁물이 많이 꼬이며, 펄세이터(2)의 회전이 반전되는 시점에서 세탁물(3)이 날개(2b)에 직접접촉되므로, 세탁물(3)에 손상을 입히는 문제점이 있다.However, according to the conventional pulsator as described above, the structure of the pulsator 2 is a structure in which the wing 2b protrudes on the substrate 2a, so that the upper part of the center of the pulsator 2 when the pulsator 2 is rotated. Rotating water flow is formed in the For this reason, when the pulsator 2 is rotated, the laundry 3 does not fall down but rotates from the top, so the laundry is twisted a lot, and the laundry 3 is winged when the rotation of the pulsator 2 is reversed. Since it is in direct contact with (2b), there is a problem that damages the laundry (3).

본 발명의 목적은 이와같은 종래 문제점을 개선하여 세탁물이 펄세이터의 날개에 직접 접촉되는 것을 줄이고, 세탁기에서 가장 이상적인 수류인 하트(Heart)형 수류를 형성하여 세탁물이 꼬이지 않게 함과 아울러 세정도를 향상시키도록 한 세탁기의 펄세이터를 제공하기 위한 것이다.The object of the present invention is to improve the conventional problems such as to reduce the laundry directly contact the wings of the pulsator, to form a heart-shaped water flow (the ideal water flow in the washing machine) so that the laundry is not twisted and the degree of cleaning It is to provide a pulsator of a washing machine to improve.

이와같은 본 발명의 목적은, 펄세이터 기판위에 복수개의 날개가 형성된 세탁기의 펄세이터에 있어서, 그 날개들의 중앙부위를 덮는 날개덮개를 형성하며, 그 날개덮개의 중앙부위에 소정직경의 망을 형성하여 세탁기의 펄세이터를 구성함으로써, 세탁조 중심부의 물이 수직강하되어 상기 망을 통하여 상기 날개들 사이로 유입되고, 그 물이 날개들에 의해 세탁조의 벽면을 타고 수직상승되는 하트형 수류를 형성하게 된다.The object of the present invention, in the pulsator of the washing machine formed with a plurality of wings on the pulsator substrate, to form a wing cover covering the central portion of the wings, a net having a predetermined diameter on the central portion of the wing cover By forming a pulsator of the washing machine, the water in the center of the washing tank is vertically lowered and flows between the wings through the mesh, and the water forms a heart-shaped water stream rising vertically on the wall of the washing tank by the wings. .

이하, 본 발명에 의한 세탁기의 펄세이터 실시예를 첨부된 도면을 참조해서 상세히 설명하면 다음과 같다.Hereinafter, a pulsator embodiment of a washing machine according to the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 발명에 의한 세탁기의 펄세이터를 보인 단면도이고, 제4도는 일체형 펄세이터의 평면도이며, 제5도는 분리형 펄세이터의 분해사시도로서, 이에 도시된 바와같이 펄세이터 기판(11)상에 복수개의 날개(12)가 형성된 펄세이터에 있어서, 그 날개(12)들의 상면 중앙부위를 덮는 날개덮개(13)와, 그 날개덮개(13)의 중앙부위에 소정직경의 수직수류 통과용 망(14)이 일체형으로 형성되어 본 발명에 의한 세탁기의 펄세이터가 구성된다.3 is a cross-sectional view illustrating a pulsator of a washing machine according to the present invention, FIG. 4 is a plan view of an integrated pulsator, and FIG. 5 is an exploded perspective view of a separate pulsator, as shown in FIG. In a pulsator having a plurality of wings 12, a wing cover 13 covering a central portion of the upper surface of the wings 12, and a vertical water flow passing network having a predetermined diameter in the central portion of the wing cover 13 ( 14) is integrally formed to constitute a pulsator of a washing machine according to the present invention.

여기서, 상기 복수개의 날개(12)가 형성된 펄세이터 기판(11)과, 상기 망이 형성된 날개덮개(13)를 분리형으로 형성하고, 각 날개(12)들의 상면 소정부위와 이에 대응된 날개덮개(13)의 소정위치에 각각 복수개의 나사공(12a)(13a)을 형성한 후 각각 나사(15)를 체결하여 구성할 수도 있다.Here, the pulsator substrate 11 having the plurality of wings 12 and the wing cover 13 having the mesh are formed in a separate type, and predetermined portions of the upper surfaces of the respective wings 12 and corresponding wing covers ( After forming a plurality of screw holes 12a, 13a at predetermined positions of 13, respectively, the screws 15 may be fastened to each other.

이와같이 분리형으로 형성하는 경우에, 복수개의 날개(12)가 형성된 펄세이터 기판(11)과, 상기 망이 형성된 날개덮개(13)를 각각 형성한후, 이를 접착제에 의해 접착시켜 구성할 수도 있다.In the case of forming the separation type as described above, the pulsator substrate 11 having the plurality of wings 12 and the wing cover 13 having the mesh formed thereon may be formed by adhering them with an adhesive.

또한, 본 발명에 의한 펄세이터(10)는 전체적으로 중심부가 오목하게 형성함으로써, 중심부에서의 수직하강 수류가 잘 형성되도록 구성한다.In addition, the pulsator 10 according to the present invention is formed so that the central portion is concave as a whole, so that the vertically falling water flow in the central portion is formed well.

이와같이 구성된 본 발명에 의한 세탁기의 펄세이터에 의하면, 펄세이터(10)의 상면에 소정직경의 날개덮개(13)가 형성되어 있으므로, 날개(12)와 세탁물과의 직접적인 접촉이 줄어들어 세탁물의 손상을 줄일 수 있다.According to the pulsator of the washing machine according to the present invention configured as described above, since the wing cover 13 having a predetermined diameter is formed on the upper surface of the pulsator 10, the direct contact between the wing 12 and the laundry is reduced, thereby preventing damage to the laundry. Can be reduced.

그리고, 펄세이터(10)가 회전되면, 제6도에 도시된 바와같이 날개덮개(13)의 하부의 날개(12) 의해 밀리는 물이 바로 상부로 올라가지 못하고 날개덮개(13)에 부딪히므로, 날개덮개(13)가 없는 가장자리 부분에서 수직상승 수류를 형성하게 된다. 이에따라 펄세이터(10)의 중앙 상부에는 수직하강 수류가 형성되어 망(14)을 통과해서 날개(12)들 사이로 유입된다.Then, when the pulsator 10 is rotated, since water pushed by the wing 12 of the lower portion of the wing cover 13 does not immediately rise to the upper portion, as shown in FIG. Vertical rising water flow is formed at the edge portion without the wing cover 13. As a result, a vertical downward flow is formed at the center of the pulsator 10 and flows through the net 14 to the wings 12.

이때, 그 망(14)을 통해서 하부로 수류가 형성되어 세탁물은 아래로 내려오게 되나, 가장자리 부근에서는 수직상승 수류가 형성되어 위로 올라가고, 아울러 펄세이터(10) 자체가 좌우 반전에 의한 회전을 하게 되므로, 세탁물이 망(14)에 빨려들거나 걸리지 않고, 가장자리 부근의 수직상승수류를 타고 위로 올라가게 된다. 즉, 하트형 수류를 타고 세탁물이 유동됨과 아울러 반복되는 역방향 물상에 의해 세탁물이 망(14)을 막거나 그 망(14)에 빨려들지 않고서 수직유동에 의해 잘 뒤집혀지면서 세탁이 이루어진다.At this time, the water flow is formed through the mesh 14 to the lower portion of the laundry is to be lowered down, but the vertical rising water flow is formed in the vicinity of the edge is raised up, and the pulsator 10 itself is rotated by the left and right reversed Thus, the laundry is not sucked into or caught by the net 14, and is lifted up by the vertical rise current near the edge. In other words, the laundry is flowed in the heart-shaped water flow and the laundry is inverted by the vertical flow without washing the net 14 or being sucked into the net 14 by the repeated reverse water phase.

따라서 제6도에 도시된 화살표 방향으로 가장자리 부분에서는 수직 상승수류가 형성되고, 중앙부에서는 수직하강 수류가 형성되므로, 종래에 같이 세탁물이 상부에 떠서 회전되지 않고, 상하로 요동되면서 골고루 되집히기 때문에 세탁효율을 높일 수 있고 아울러 세탁물의 꼬임도 줄어든다.Therefore, vertical rising water flow is formed at the edge portion in the direction of the arrow shown in FIG. 6, and vertical falling water flow is formed at the center portion thereof. Thus, laundry is not rotated and rotated up and down, and it is evenly rotated up and down. The efficiency can be increased, and the twist of the laundry is reduced.

이상에서 상세히 설명한 바와같이 본 발명에 의한 펄세이터에 의하면, 세탁조의 벽 부근에서는 수직상승수류가 형성되고, 중심부에서는 수직하강 수류가 형성되므로, 세탁시 가장 효율적인 세탁을 수행할 수 있는 하트형 수류를 형성시킬 수 있다. 이에따라 세정도를 향상시키과 아울러 세탁물의 꼬임 등을 줄일 수 있는 효과가 있다. 또한 세탁물과 펄세이터의 날개의 직접 접촉을 줄임으로써, 세탁물의 손상을 방지할 수 있는 효과가 있다.As described in detail above, according to the pulsator according to the present invention, since the vertical upward flow is formed in the vicinity of the wall of the washing tank, and the vertical downward flow is formed in the center, the heart-shaped water stream capable of performing the most efficient washing at the time of washing. Can be formed. Accordingly, it is possible to improve the degree of cleaning and to reduce the kinks of the laundry. In addition, by reducing the direct contact between the laundry and the wings of the pulsator, there is an effect that can prevent the damage to the laundry.
