It is about.

종래의 전자동 세탁기는 제1도에서 보는 바와같이, 외조(1)의 내부에 사탁겸용탈수조(2)가 회전가능하게 설치되고, 상기 세탁겸용탈수조의 내부 밑면에 회전자(Agitator)(3)가 설치되며, 상기 탈수조(2) 및 회전자는 외조의 중앙밑면에 설치된 클러치(4)의 탈수축(6)및 세탁축에 각각 체결되고, 상기 외조(1)의 밑면 축부에 설치된 모터(7)와 상기 클러치(4)는 V벨트로 전동되는 구조로 구성되어 있다.In the conventional fully automatic washing machine, as shown in FIG. 1, a combined-use dehydration tank 2 is rotatably installed inside the outer tub 1, and an agitator 3 is disposed on the inner bottom of the combined-use dehydration tank. Is installed, the dehydration tank (2) and the rotor is fastened to the dehydration shaft (6) and the washing shaft of the clutch (4) installed on the central bottom of the outer tub, respectively, the motor (7) installed on the bottom shaft portion of the outer tub (1) ) And the clutch 4 are constituted of a structure that is transmitted by a V belt.

또한 상기 클러치(4)를 상세하게 설명하면, 제2도에서 보는 바와같이 V벨트 풀리로 부터 직접 동력을 전달받는 기어축(11)의 하부에 체결된 스프링 불록(12)과, 상부탈수축(5) 및 브레이크 드럼겸 기어하우징(13)과 일체인 하부 탈수축(14)의 외주면에 설치되어 모터의 회전구동력을 세탁시에는 탈수축에 전달하지 않고 탈수시는 전달하는 클러치스프링(15)과, 상기 클러치 스프링의 외주면에 결합되고 외주면에 톱니(16a)가 형성된 클러치 보스(16)와, 외조(1)의 측부에 설치된 배수벨브 작동겸용 솔레노이드(도시되지 않음)에 연동되는 브레이크 레버(17)의 하단부에 회동 가능하세 설치되어 상기 클러치보스(16)의 톱니(16a)에 걸리는 캠(18)과 세탁겸용 탈수조(2)의 역회전 방지를 위한 일방향 스프링 클러치(19)와, 세탁시기어축(11)의 동력을 세탁축(6)에 감속 전달하는 유성기어(20)와, 브레이크 드럼겸용 기어하우징(13)의 외주면 감싸는 브레이크 밴드(21)등으로 구성되어 있다.In addition, the clutch 4 will be described in detail. As shown in FIG. 2, a spring block 12 fastened to a lower portion of a gear shaft 11 directly receiving power from a V-belt pulley and an upper dehydration shaft ( 5) and the clutch spring 15 which is installed on the outer circumferential surface of the lower dehydration shaft 14 integrated with the brake drum and the gear housing 13 to transfer the rotational driving force of the motor to the dehydration shaft when washing, And a brake lever 17 coupled to an outer circumferential surface of the clutch spring and interlocked with a clutch boss 16 having teeth 16a formed on the outer circumferential surface thereof, and a drain valve actuating solenoid (not shown) installed at the side of the outer tub 1. One-way spring clutch (19) for preventing the reverse rotation of the cam (18) caught by the teeth (16a) of the clutch boss 16 and the combined use dewatering tank (2) installed on the lower end of the clutch boss 16, washing machine Slowly transfer the power of the shaft 11 to the washing shaft 6 Is composed of a planetary gear 20 and a brake band 21 surrounding the outer circumferential surface of the gear housing 13 for a brake drum.

일반적으로 전자동 세탁의 구동장치는 제1도에서 보는 바와같이 탈수조(2)는 정지해 있고 회전자(3)의 좌우 교반으로 세탁물을 세탁하는 세탁모드(mode)와 상기 탈수조(2) 및 회전자(3)가 동일 속도로 고속 회전하는 탈수모드로 나누어지는데 이때의 동작설명을 상세히 하면 다음과 같다.In general, the driving device of the automatic washing machine, as shown in FIG. 1, the dehydration tank 2 is stopped and the washing mode for washing the laundry by left and right stirring of the rotor 3 and the dehydration tank 2 and The rotor 3 is divided into a dehydration mode in which a high speed rotates at the same speed. The operation of the rotor 3 is described in detail as follows.

먼저, 세탁시(세탁모드)에는 V벨트를 클러치(4)에 전달된 모터의 정방향(Forward)회전동력은 스프링 클러치(15)가 감기는 방향이므로 스프링 블럭(12)에 의해 하부 탈수축(14)로 전달되어야 하지만 상기 스프링 클러치(15)의 외주면에 설치된 클러치 보스(16)의 톱니(16a)를 클러치 보스캠(18)이 밀어주고 있어 스프링 클러치의 감김을 방지하여 탈수축(5)으로의 동력전달을 막는다. 따라서 기어축(11)에 전달된 회전동력은 유성기어를 통해 감속되어 세탁축(6)으로 전달되고 상기 세탁축(6)에 체결된 회전자(3)을 회전시켜 세탁한다.First, during washing (washing mode), the forward rotational power of the motor transmitted to the clutch 4 of the V-belt is a direction in which the spring clutch 15 is wound so that the lower dehydration shaft 14 is prevented by the spring block 12. However, the clutch boss cam 18 pushes the teeth 16a of the clutch boss 16 installed on the outer circumferential surface of the spring clutch 15 to prevent the spring clutch from being wound to the dehydration shaft 5. Prevent power transmission; Therefore, the rotational power transmitted to the gear shaft 11 is decelerated through the planetary gear, and is transmitted to the washing shaft 6 and rotates the rotor 3 fastened to the washing shaft 6 to wash.

또한 상기 모터(7)의 역방향(Reverse) 회전동력은 스프링 클러치(15)가 풀리는 방향이므로 이때에도 기어축(11)의 회전동력을 탈수축에는 전달 할수 없으므로 유성기어를 통해 감속되어 세탁축(6)으로 전달되고 상기 세탁축(6)에 체결된 회전자(3)을 회전시켜 세탁한다.In addition, since the reverse rotational power of the motor 7 is a direction in which the spring clutch 15 is released, the rotational power of the gear shaft 11 can not be transmitted to the dehydration shaft at this time. ) Is rotated and the rotor (3) fastened to the laundry shaft (6) to wash.

그리고 상기 유성기어(20)를 통한 감속시 기어하우징(13)에 반작용 회전 토크가 발생하게 되는데 이 반작용 회전 토크에 의한 탈수축의 역회전은 역회전 방지용 일방향 클러치(19)와, 브레이크 드럼겸용 기어하우징(13)의 외주면을 소정의 압력으로 감싸고 있는 브레이크 밴드(21)에 의해 확실하게 규제된다.In addition, a reaction rotation torque is generated in the gear housing 13 during deceleration through the planetary gear 20. The reverse rotation of the dehydration shaft caused by the reaction rotation torque is a one-way clutch 19 for preventing reverse rotation, and a brake drum combined gear housing. It is reliably regulated by the brake band 21 which wraps the outer peripheral surface of (13) by predetermined pressure.

탈수시(탈수모드)에는 V벨트로 클러치(4)에 전달된 모터의 회전동력은 항시 정방향(Forward) 회전을 하게 되므로 스프링 클러치(15)는 감기는 방향으로 동작되어 스프링 클러치(15)와 스프링 블록(12) 사이가 밀착되도록 벨브 작동용 솔레노이드는 온(ON)되어 레버(22)를 당기게되고 상기 레버(22)와 연동되는 브레이크 레버(17)의 캠(18)을 클러치 보스(16)의 톱니(16a)로 부터 벗어나게 하는 동시에 브레이크 밴드(21)가 기어 하우징(13)의 외주면에서 벗어나게 함으로써 스프링 블록(12)의 회전동력이 기어하우징의 하부축(14)으로 전달되어 기어하우징(13) 및 상기 기어하우징(13)과 일체인 탈수축(5)를 감속없이 고속으로 회전시키게 되며, 따라서 세탁축(6) 및 탈수축(5)을 일방향으로 고속 회전시켜 세탁물의 탈수를 수행하게 된다.During dehydration (dehydration mode), the rotational power of the motor transmitted to the clutch 4 by the V belt is always in the forward rotation, so the spring clutch 15 is operated in the winding direction so that the spring clutch 15 and the spring are rotated. The valve actuation solenoid is turned on to pull the lever 22 so that the blocks 12 are in close contact with each other, and the cam 18 of the brake lever 17 interlocked with the lever 22 is moved by the clutch boss 16. By disengaging from the teeth 16a and the brake band 21 deviating from the outer circumferential surface of the gear housing 13, the rotational power of the spring block 12 is transmitted to the lower shaft 14 of the gear housing so that the gear housing 13 And the dehydration shaft 5 integral with the gear housing 13 is rotated at high speed without deceleration, and thus, the washing shaft 6 and the dewatering shaft 5 are rotated at high speed in one direction to perform dehydration of the laundry.

이후, 탈수가 완료되거나 탈수도중 강제로 탈수 공정이 중지 당할 경우 배수벨브 작동용 솔레노이드가 오프(OFF)되어 브레이크레버(17)를 놓아주게 되면 캠(18)은 클러치보스(16)의 톱니(16a)사이에 걸리게 되는 동시에 브레이크 밴드(21)가 기어하우징(13)의 외주면을 압착하여, 세탁 모드로 전환되면서 브레이크 드럼 겸용인 기어하우징(13)의 회전 동작을 정지시키게 되고, 따라서 상기 기어하우징(13)과 탈수축(5)를 통하여 체결된 탈수조(2)도 정지하게 된다.Then, when dehydration is completed or the dehydration process is forcibly stopped during dewatering, when the drain valve actuating solenoid is turned off and the brake lever 17 is released, the cam 18 has the teeth 16a of the clutch boss 16. At the same time, the brake band 21 compresses the outer circumferential surface of the gear housing 13 to switch to the washing mode to stop the rotation operation of the gear housing 13 which is also used as a brake drum, and thus the gear housing ( 13) and the dehydration tank 2 fastened through the dehydration shaft 5 are also stopped.

종래 세탁기 구동장치의 문제점은 상기한 바와같이 모터(7)와 클러치가 별도로 설치되어 모터(7)의 동력이 V벨트(10)을 통하여 클러치(4)로 전달되는 구조로써 전제적인 구성이 복잡하고, 세탁과 탈수시 회전동력을 선택적으로 단속하는 기능과 감속기능을 같는 클러치(4)의 구조도 매우 복잡할뿐만 아니라, V벨트에 의한 회전동력 전달시 동력이 손실되는 등의 문제점이 있다.The problem of the conventional washing machine driving device is that the motor 7 and the clutch are separately installed as described above, so that the power of the motor 7 is transmitted to the clutch 4 through the V-belt 10, and the premise is complicated. In addition, the structure of the clutch 4 having the same function of selectively controlling the rotational power during washing and dehydration and the deceleration function is also very complicated, and there is a problem such that the power is lost when the rotational power is transmitted by the V-belt.

본 고안은 상기한 바와같은 종래의 결함을 해소하기 위하여 안출한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve the conventional defects as described above and described in detail by the accompanying drawings as follows.

제3도에서 보는 바와같이 외조(31)에 고정되는 모터(32)의 축(33)에 회전자(Agitator)(34)를 설치하고 동시에 탈수조(35)도 부싱A, B(36),(37)로 세탁축(43)에 회전지지되며 상기 세탁축(43)과 탈수조(35)에 각각 맞물림 돌기(40)(39)가 설치되어 있다.As shown in FIG. 3, an agitator 34 is installed on the shaft 33 of the motor 32 fixed to the outer tub 31, and at the same time, the dehydration tank 35 also includes bushings A, B 36, (37) is rotatably supported on the washing shaft 43, and engaging projections 40 and 39 are respectively installed on the washing shaft 43 and the dehydration tank 35.

세탁축(43)은 제4도에서 보는바와같이 세탁축 단차(38)를 두어 탈수조(35)의 자중에 의한 처짐을 방지시키며, 탈수조 돌기(39)에는 제5도에서 보는 바와같이, 양족에 세탁축 돌기(40)와 접촉하는 부분에 충격을 줄여주는 완충재(42)가 부착되어져 있다.The washing shaft 43 has a washing shaft step 38 as shown in FIG. 4 to prevent sagging due to the weight of the dehydrating tank 35, and the dehydrating tank protrusion 39 as shown in FIG. Both ends are attached with a cushioning material 42 to reduce the impact on the portion in contact with the washing shaft projection (40).

전자동 세탁이에 있어서 회전자(34)가 에지테이터형일때 세탁시 에지테이터의 회전각도는 통산 360°를 넘지 않는다 (보통 180°∼ 220°), 따라서 제5도에서 보는바와같이 세탁축 돌기(40)와 탈수조돌기(39)가 서로 맞물리지 않고 세탁축(43)만의 회전이 가능해지고, 이러한 상태에서 에지테이터를 좌우교반(Agifatig)하면서 세탁한다.In the fully automatic washing machine, when the rotor 34 is an edge data type, the rotation angle of the edge data during washing does not exceed 360 ° in total (usually 180 ° to 220 °), and thus, as shown in FIG. 40 and the dehydration tank protrusion 39 can rotate only the washing shaft 43 without being engaged with each other, and wash the edge data while agitating the edge data in this state.

이때 탈수조(35)는 정지상태가 아니라 에지테이터에 의한 세탁물 및 세액의 영향으로 에지테이터 회전방향으로 회전할려는 성질을 가지지만 이러한 탈수조의 회전현상은 유체에 의한 토크의 전달이기 때문에 에지테이터의 회전과 일정한 시간간격을 두고 발생하게 된다. 따라서 에지테이터의 회전주기를 상기 일정시간 간격이하로 교반하면 탈수조(35)와 회전자(34) 회전방향이 동일하지 않게하면서도 세탁이 가능해지므로 세탁시 탈수조(35)의 회전을 구속 할 필요가 없다.At this time, the dehydration tank (35) has the property of rotating in the direction of edge data rotation under the influence of the laundry and the washing liquid by the edge data, not the stationary state, but the rotation phenomenon of the dehydration tank is the transfer of torque by the fluid It occurs with rotation and a certain time interval. Therefore, when the rotation period of the edge data is stirred below the predetermined time interval, it becomes possible to wash while the rotation direction of the dehydration tank 35 and the rotor 34 are not the same, so it is necessary to restrain the rotation of the dehydration tank 35 during washing. There is no.

만약 세탁시 외부의 교란(세탁물 상태의 급격한 변화돈)에 의하여 세탁축 돌기(40)와 탁수돌기(39)가 맞물리게 되는 경우가 있더라도 탈수조(35)는 구속이 자유로운 상태이기 때문에 문제없다.If there is a case where the washing shaft projection 40 and the turbidity projection 39 are engaged due to external disturbance (a drastic change in the state of the laundry) during washing, the dehydration tank 35 is free of restraints because it is in a free state.

이후 세탁이 끝나고 탈수가 시작되면 모터는 일방향으로 계속회전 하게되고 따라서 세탁축 돌기(40)와 탈수축 돌기(39)가 맞물려 모터축(33)의 회전토크를 탈수축(41)에 전달하여 탈수공정을 수행한다.After the washing is finished and the dehydration starts, the motor continues to rotate in one direction, and thus the washing shaft protrusion 40 and the dehydration protrusion 39 are engaged to transfer the rotational torque of the motor shaft 33 to the dehydration shaft 41 to dewater. Perform the process.

탈수시 간섭(Intrupt)에 의한 제등 또는 급제동시는 모터의 발전제동을 이용하여 제동할수도 있는데 이때는 모터축(33)이 구속되므로 탈수조 돌기(39)가 제5도의 모터축(33) 회전 가능각도 만큼 회전하여 탈수와 반대면에서 세탁축 돌기(40)와 맞물려 제동이 수행된다.When dehydration or sudden braking due to interruption (Intrupt) can also be braked by using the power generation braking of the motor. In this case, the motor shaft 33 is constrained, so the dehydration tank protrusion 39 can rotate the motor shaft 33 of FIG. Rotation by an angle is engaged with the washing shaft projection 40 on the opposite side to dewatering and braking is performed.

이상에서 설명한 바와같은 본 고안의 전자동 세탁기 구동장치는 클러치가 필요 없을 뿐아니라 벨트 풀리등의 구동장치가 필요없고, 축이 하나이기 때문에 구조가 매우 간단하고 경제적이다.As described above, the fully automatic washing machine drive device of the present invention does not require a clutch, and does not require a drive device such as a belt pulley, and because the shaft is one, the structure is very simple and economical.
