본 고안은 세탁기에 관한 것으로서, 더욱 상세하게는 세탁시 교반날개와 회전조가 역방향으로 회전되도록 함으로서, 세탁효율이 향상되도록한 세탁기에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a washing machine to improve the washing efficiency by rotating the stirring blade and the rotating tub in the reverse direction when washing.

일반적으로 세탁기는 제1도에 도시된 것처럼, 외주면에 구멍(2a)이 무수히 많이 형성된 회전조(2)를 감싸는 수조(2b), 회전조(2) 내부 바닥에 설치된 교반날개(1), 그리고 교반날개(1)와 연결된 세탁축(3)에 중공상으로 끼워진 탈수축(4)을 선택적으로 정역회전 시키는 동력절환장치(5)가 구비된다. 이때 탈수축(4)은 상단이 회전조(2)와 연결되고 동력절환장치(5)는 모터(5a)로 회전된다.In general, the washing machine as shown in Figure 1, the water tank (2b) surrounding the rotating tank (2) formed with a large number of holes (2a) on the outer peripheral surface, the stirring blade (1) installed on the inner bottom of the rotating tank (2), and A power switching device 5 is provided to selectively reversely rotate the dewatering shaft 4 fitted in a hollow shape on the washing shaft 3 connected to the stirring blade 1. At this time, the dehydration shaft 4 is the upper end is connected to the rotary tank 2 and the power switching device 5 is rotated by the motor (5a).

이처럼 구성된 종래의 세탁기는 회전조(2) 내부에 물과 세탁물을 함께 넣으면 물은 구멍(2a)을 통하여 수조(2b)로 유입되므로 수조(2b)와 회전조(2)의 수위가 동일해 진다. 이런 상태에서 세탁시 동력절환장치(5)가 정 역회전되어 세탁축(3)과 교반날개(1)가 정역회전 된다. 즉 수류가 형성되면서 세탁물이 세탁된다. 이때 클러치(7)는 풀린 상태이고 브래이크(6)는 회전조(2)를 잡고 있기 때문에 탈수축(4)과 회전조(2)는 정지상태이다.In the conventional washing machine configured as described above, when water and laundry are put together in the rotating tub 2, the water flows into the water tank 2b through the hole 2a, so that the water level of the water tank 2b and the rotary tank 2 becomes the same. . In this state, the power switch 5 is reversely rotated during washing so that the washing shaft 3 and the stirring blade 1 are reversely rotated. That is, the laundry is washed while the water flow is formed. At this time, since the clutch 7 is in an unlocked state and the brake 6 is holding the rotary tub 2, the dehydration shaft 4 and the rotary tub 2 are in a stopped state.

한편 탈수시에는 수조(2b) 내부의 물이 배수된 상태에서 회전조(2)와 교반날개(1)가 고속으로 회전되므로 원심력에 의해 세탁물이 탈수된다. 즉 클러치(7)가 잠김상태로 됨과 동시에 브래이크(6)가 풀리므로 세탁축(3)과 탈수축(4)이 일체로 된 상태에서 고속으로 회전된다.On the other hand, during the dehydration, the rotary bath 2 and the stirring blade 1 are rotated at a high speed while the water in the water tank 2b is drained, so that the laundry is dewatered by centrifugal force. That is, since the clutch 7 is locked and the brake 6 is released, the clutch 7 is rotated at a high speed while the washing shaft 3 and the dewatering shaft 4 are integrated.

그러나 세탁시 교반날개(1)만 회전하기 때문에 세탁량이 많을 경우 골고루 세탁되지 않는 단점이 있다. 즉 교반날개(1)에 과부하가 걸려 회전수류가 활발하게 일어나지 않게되어 세탁력이 저하된다. 또한 교반날개(1)의 회전력을 증가 시키면 세탁물과의 마찰로 인하여 세탁물이 손상되는 등의 단점이 있다.However, when the washing blade rotates only when the stirring blade (1) there is a disadvantage that even washing is not evenly. That is, the overloading of the stirring blade (1) is prevented from actively rotating rotation flow force is reduced. In addition, increasing the rotational force of the stirring blade (1) has a disadvantage, such as damage to the laundry due to friction with the laundry.

본 고안은 상기와 같은 문제점을 개선하기 위해 안출된 것으로서, 본 고안의 목적은 세탁시 교반날개와 회전조가 역방향으로 회전되도록 함으로서, 교반날개에 의한 회전수류와 회전조에 의한 회전수류가 서로 충돌되면서 복합적으로 일어나도록 하여 세탁효율이 향상되도록한 세탁기를 제공함에 있다.The present invention is devised to improve the above problems, the purpose of the present invention is to rotate the stirring blade and the rotating tank in the reverse direction when washing, the rotating water flow by the stirring blade and the rotating water flow by the rotating tank collide with each other It is to provide a washing machine so as to improve the washing efficiency.

상기 목적을 달성하기 위하여 본 고안은, 저부에 세탁축이 형성된 교반날개, 상기 교반날개가 내부에 회전가능토록 설치된 회전조, 상기 세탁축에 끼워지는 중공상의 탈수축, 상기 세탁축과 탈수축을 선택적으로 회전시키는 동력절환장치, 그리고 상기 세탁축이 회전될 때 상기 탈수축이 브래이크에 의해 제동된 상태로 상기 회전조가 반대방향으로 회전되는 회전수단을 구비하는 특징이 있다.In order to achieve the above object, the present invention provides a stirring blade having a washing shaft formed at a bottom thereof, a rotating tub installed so that the stirring blade is rotatable therein, a hollow dewatering shaft fitted to the washing shaft, and the washing shaft and the dewatering shaft are selected. And a rotation means for rotating the rotating tub in the opposite direction with the dehydration shaft being braked by the brake when the laundry shaft is rotated.

이하에서는 첨부도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

제2도는 본 고안의 정단면도이고 제3도는 제2도의 A-A선 단면도이다. 본 고안을 설명할 때 제1도와 동일 구성요소는 동일부호를 사용하여 본 고안을 설명한다. 즉 동력절환장치(5)에 의해 구동되는 세탁축(3), 중공상으로 세탁축(3)에 끼워지고 상,하부로 베어링(14)에 의해 회전 지지되는 탈수축(4), 그리고 세탁축(3)이 정,역회전될 때 세탁축(3)과 치합된 상태로 회전조(2)가 반대방향으로 정,역회전되는 회전수단(A)이 구비된다.2 is a front sectional view of the present invention, and FIG. 3 is a sectional view taken along the line A-A of FIG. When describing the present invention, the same elements as in FIG. 1 describe the present invention using the same reference numerals. That is, the washing shaft (3) driven by the power switching device (5), the dewatering shaft (4), which is fitted into the washing shaft (3) in a hollow shape and rotated and supported by the bearing (14) up and down, and the washing shaft. When the (3) is rotated forward and reverse, the rotating means (2) is provided with the rotating tank (2) in the opposite direction in the engaged state with the washing shaft (3).

즉 세탁시 동력절환장치(5)에 의해 세탁축(3)과 교반날개(1)가 정,역회전된다.In other words, the washing shaft 3 and the stirring blade 1 is rotated forward and reverse by the power switching device 5 during washing.

이때 세탁축(3)과 치합된 회전조(2)가 교반날개(1)와 반대방향으로 정,역회전 된다. 따라서 회전조(2)에 의한 회전수류와 교반날개(1)에 의한 회전수류가 서로 충돌 되면서 복합적인 회전수류가 발생된다.At this time, the rotating tank (2) engaged with the washing shaft (3) is rotated forward and reverse in the opposite direction to the stirring blade (1). Therefore, the rotating water flow by the rotating tank 2 and the rotating water flow by the stirring blade 1 collide with each other to generate a complex rotating water flow.

회전수단(A)은 세탁축(3)을 감싸도록 회전조(2) 저면에 형성된 내접기어(9), 내접기어(9)와 대응되도록 세탁축(3)에 형성된 선기어(8), 선기어(8)와 내접기어(9) 사이에 방사상으로 다수개 배치되어 서로 치합되는 유성기어(10), 내접기어(9) 하부가 닫히도록 탈수축(4) 상단에 형성된 원판(11), 그리고 유성기어(10)가 끼워져 자전되면서 공전되도록 원판(11) 표면에 다수개 돌출 형성된 핀(12)이 구비된다.The rotating means (A) is a sun gear (8) formed on the washing shaft (3) so as to correspond to the internal gear (9), the internal gear (9) formed on the bottom of the rotating tank (2) to surround the washing shaft (3), sun gear ( 8) and a disk (11) formed on the top of the dehydration shaft (4) to close the lower portion of the internal gear (9), the inner gear (9) is arranged radially disposed between the internal gear (9) and a number of radial gears The pin 12 is provided with a plurality of protruding on the surface of the disk 11 so that the 10 is inserted and rotated.

그리고 원판(11)의 외주연으로 브래이크(6)가 설치되어 세탁시 탈수축(4)이 정지되도록 원판(11)을 잡는다. 한편 내접기어(9)의 외주면 상측으로 밀폐부재(13)가 형성되어 수조(2b)의 하단과 결합된다. 이때 밀폐부재(13)는 수조(2b)에 고정설치된 것으로서, 회전조(2)의 회전에 따른 마찰력이 감소됨과 동시에 누수를 방지하는 것이다. 한편 수조(2b) 내주면에는 방사상으로 다수개의 교반봉(2c)이 형성된다. 즉 회전조(2)가 회전 될 때 회전조(2) 내주면에 돌출된 교반봉(2c)이 물살을 가르므로 회전수류가 적극적으로 발생된다.Then, the brake 6 is installed at the outer circumference of the disc 11 to hold the disc 11 so that the dehydration shaft 4 is stopped during washing. On the other hand, the sealing member 13 is formed above the outer circumferential surface of the internal gear 9 and is coupled to the lower end of the water tank 2b. At this time, the sealing member 13 is fixed to the water tank 2b, and the frictional force due to the rotation of the rotating tank 2 is reduced and at the same time to prevent leakage. On the other hand, a plurality of stirring rods 2c are formed radially on the inner circumferential surface of the water tank 2b. In other words, when the rotating tub 2 is rotated, the stirring bar 2c protruding from the inner circumferential surface of the rotating tub 2 divides the water, thereby actively generating the rotating water flow.

이처럼 구성된 본 고안의 세탁과정을 설명하면 다음과 같다. 즉 회전조(2) 내부에 물과 세탁물을 넣는다. 이때 구멍(2a)을 통하여 물이 수조(2b)로 유입되므로 수조(2b)와 회전조(2)의 수위가 동일해진다. 이런 상태에서 모터(5a)를 구동 시키면 동력절환장치(5)가 세탁축(3)을 정역회전시킨다. 이때 클러치(7)는 풀린 상태이고 브래이크(6)에 의해 탈수축(4)은 제동된 상태이다.The washing process of the present invention configured as described above is as follows. That is, water and laundry are put in the rotating tub (2). At this time, since water flows into the water tank 2b through the hole 2a, the water level of the water tank 2b and the rotating tank 2 becomes the same. When the motor 5a is driven in this state, the power switching device 5 rotates the washing shaft 3 forward and backward. At this time, the clutch 7 is in an unlocked state and the dehydration shaft 4 is braked by the brake 6.

한편 세탁축(3)이 정역회전되는 동안 교반날개(1)가 함께 정, 역회전되면서 회전수류가 발생되고 이 회전수류에 의해 세탁물은 세탁된다. 또한 제3도에 도시된 것처럼 세탁축(3)에 형성된 선기어(8)가 회전되면서 각 유성기어(10)가 반대방향으로 회전된다. 이때 각 유성기어(10)와 치합된 내접기어(9)가 유성기어(10)와 동일방향으로 회전되면서 회전조(2)가 회전된다. 따라서 회전조(2)의 회전방향으로 회전수류가 발생되고 또한 교반봉(2c)에 의해 회전수류가 적극적으로 발생된다.Meanwhile, while the washing shaft 3 rotates forward and backward, the stirring blades 1 rotate forward and backward together to generate a rotational flow and the laundry is washed by the rotational flow. In addition, as shown in FIG. 3, each of the planetary gears 10 is rotated in the opposite direction as the sun gear 8 formed on the washing shaft 3 is rotated. At this time, while the internal gear 9 meshed with each planetary gear 10 rotates in the same direction as the planetary gear 10, the rotating tank 2 is rotated. Therefore, rotational water flow is generated in the rotational direction of the rotating tub 2, and rotational water flow is actively generated by the stirring rod 2c.

즉 교반날개(1)가 정회전 되는 동안 회전조(2)는 역회전 되고 교반날개(1)가 역회전 되는 동안 회전조(2)는 정회전 되면서 회전수류가 반대방향으로 발생된다. 이때 서로 반대방향인 회전수류가 충돌되면서 복합적인 회전수류가 발생된다. 한편 세탁축(3)과 회전조(2)의 회전비는 다음과 같다.That is, while the rotating blade 2 is reversely rotated while the stirring blade 1 is rotated forward, the rotating tank 2 is rotated forward while the stirring blade 1 is rotated reversely. At this time, rotational currents in opposite directions collide with each other to generate a complex rotational current. On the other hand, the rotation ratio of the washing shaft 3 and the rotating tub 2 is as follows.

Ws = rW/RWs = rW / R

(단 Ws는 회전조(2)의 회전속도를, W는 세탁축(3)의 회전속도를, r은 세탁축(3)의 반지름을, R은 내접기어(9)의 반지름을 각각 나타낸다.)(Ws denotes the rotational speed of the rotating tub 2, W denotes the rotational speed of the washing shaft 3, r denotes the radius of the washing shaft 3, and R denotes the radius of the internal gear 9, respectively. )

상기 식에서 회전조(2)가 세탁축(3)보다 회전속도가 느리게 되므로 결과적으로 회전조(2)가 교반날개(1)보다 느리게 정 역회전됨을 알 수 있다. 즉 회전조(2)는 교반날개(1)보다 부피가 크므로 회전속도가 상대적으로 저속으로 된다. 따라서 동력절환장치(5)에 과부하가 걸리지 않는다.In the above formula, since the rotation speed of the rotating tub 2 is slower than that of the washing shaft 3, it can be seen that the rotating tub 2 rotates forward and backward more slowly than the stirring blade 1. That is, since the rotating tank 2 is larger in volume than the stirring blade 1, the rotating speed becomes relatively low. Therefore, the power switching device 5 is not overloaded.

한편 탈수과정을 설명하면 다음과 같다. 즉 세탁이 완료되면 물을 배수한 다음 클러치(7)를 잠근다. 이때 세탁축(3)과 탈수축(4)이 일체화 된다. 한편 브래이크(6)를 해제하여 탈수축(4)이 자유롭도록 한 다음 동력절환장치(5)가 작동된다. 이때 세탁축(3)과 탈수축(4)이 동시에 일방향으로 고속회전 된다. 한편 탈수축(4)이 회전될 때 원판(11)에 형성된 핀(12)과 유성기어(10) 역시 같은 방향으로 회전 되므로 유성기어(10)와 치합된 내접기어(9)가 함께 회전된다. 따라서 교반날개(1)와 회전조(2)가 회전 되면서 세탁물이 탈수된다.Meanwhile, the dehydration process is as follows. That is, when the washing is completed, drain the water and then lock the clutch (7). At this time, the washing shaft 3 and the dewatering shaft 4 are integrated. On the other hand, the brake 6 is released to free the dehydration shaft 4 and then the power switch 5 is operated. At this time, the washing shaft 3 and the dewatering shaft 4 are rotated at one time in a high speed. Meanwhile, when the dehydration shaft 4 is rotated, the pin 12 formed on the disc 11 and the planetary gear 10 are also rotated in the same direction, so that the internal gear 9 engaged with the planetary gear 10 rotates together. Therefore, the washing blade is dehydrated while the stirring blade (1) and the rotating tank (2) is rotated.

이상에서와 같이 본 고안에 따르면 세탁시 교반날개와 회전조가 서로 반대방향으로 회전 된다. 따라서 교반날개에 의한 회전수류와 회전조에 의한 회전수류가 서로 충돌되면서 세탁물이 세탁되므로 세탁효율이 향상되는 효과가 있다.As described above, according to the present invention, the stirring blade and the rotating tub are rotated in opposite directions when washing. Therefore, the washing water is washed while the rotating water flow by the stirring blades and the rotating water flow by the rotary tub are impacted, thereby improving washing efficiency.
