본 발명은 전자동 세탁기의 구동장치에 관한 것으로서, 특히 모터의 회전력을 세탁날개와 세탁조에 선택적으로 전달하며 세탁 및 헹굼행정과 탈수행정을 수행하도록 된 전자동 세탁기의 클러치에 관한 것이다.The present invention relates to a driving device of a fully automatic washing machine, and more particularly, to a clutch of a fully automatic washing machine to selectively transmit the rotational force of the motor to the washing blade and the washing tank and to perform the washing and rinsing stroke and the dehydrating stroke.

일반적으로, 전자동 세탁기는 세제의 유화 작용 및 세탁날개(Pulsator)의 회전에 따른 수류의 마찰작용 및 세탁날개가 세탁물에 가하는 충격작용 등을 이용하여 의복, 침구 등에 부착된 각종 오염 물질을 제거하는 제품으로서, 센서에 의해 세탁물의 양과 종류를 감지하여 세탁방법을 자동으로 설정하고 또한 세탁수를 세탁물의 양과 종류에 따라 적절한 수위까지 급수한 후 마이콤의 제어를 받아 세탁을 수행하게 된다.In general, a fully automatic washing machine removes various contaminants attached to clothes, bedding, etc. by using the emulsification action of the detergent and the friction action of the water flow due to the rotation of the pulsator, and the impact action of the washing wing on the laundry. As the sensor detects the amount and type of laundry, the washing method is automatically set, and the washing water is supplied to an appropriate level according to the amount and type of the laundry, and then washing is performed under the control of the microcomputer.

이와 같은, 종래의 전자동 세탁기는 도 1에 나타낸 바와 같이, 아웃케이스(11) 내에 설치된 외조(2) 내부에 다수의 탈수공을 갖는 탈수조 겸용 세탁조(12)가 회전가능하게 설치되고, 상기 세탁조(12)의 하부 중앙에는 세탁날개(1)가 회전가능하게 설치되며, 상기 외조(2)의 하부에는 상기 세탁조(12) 및 세탁날개(1)에 동력을 전달하기 위한 클러치(4)가 설치된다.As shown in FIG. 1, the conventional fully automatic washing machine is rotatably provided with a dehydration tank combined washing tank 12 having a plurality of dehydration holes in the outer tank 2 installed in the outer case 11. In the center of the lower portion of the washing blade (1) is rotatably installed, the lower portion of the outer tank (2) is provided with a clutch (4) for transmitting power to the washing tank 12 and the washing blade (1) do.

또한, 상기 외조(2)의 하부 일측에는 모터(3)가 설치되며, 상기 모터(3)의 축 선단에 결합된 모터 풀리(13)와 클러치(4)에 연결된 클러치 풀리(14) 사이에는 V벨트(15)가 연결된다.In addition, a motor 3 is installed at one lower side of the outer tub 2, and between the motor pulley 13 coupled to the shaft end of the motor 3 and the clutch pulley 14 connected to the clutch 4. The belt 15 is connected.

한편, 클러치(4)는 도 2에 나타낸 바와 같이, 클러치 풀리(14) 상부에 기어 샤프트(5)가 설치되고, 기어 샤프트(5) 상부에 세탁축(16)이 설치되며, 상기 세탁 축(16) 외측에는 탈수축(17)이 설치된다.Meanwhile, as shown in FIG. 2, the clutch 4 has a gear shaft 5 installed above the clutch pulley 14, a washing shaft 16 installed above the gear shaft 5, and the washing shaft ( 16) Dehydration shaft 17 is provided on the outside.

이 때, 상기 탈수축(17) 하단부는 상부 기어 하우징을 겸하는 브레이크 드럼(18a)에 고정되고, 상기 브레이크 드럼(18a) 하부에는 하부 기어 하우징(18b)이 결합되며, 브레이크 드럼(18a) 내부에는 동력을 감속시키기 위한 기어 유니트(19)가 설치된다.At this time, the lower end of the dehydration shaft 17 is fixed to the brake drum (18a) also serves as the upper gear housing, the lower gear housing (18b) is coupled to the lower portion of the brake drum (18a), inside the brake drum (18a) A gear unit 19 for reducing power is provided.

그리고, 기어 샤프트(5)의 하단부에는 스프링 블록(10) 및 클러치 보스(6)가 고정되고, 클러치 보스(6) 외주에는 배수밸브 작동겸용 솔레노이드(도시는 생략함)의 동작에 따라 연동하는 브레이크 레버(20)가 설치되며, 상기 브레이크 레버(20) 일측에는 상기 브레이크 레버(20)의 작동시 연동하도록 클러치 레버(23)가 설치되고, 상기 클러치 레버(23)의 하단부에는 클러치 레버(23)의 작동시 연동하여 회동하는 작동캠(21)이 설치된다.In addition, a spring block 10 and a clutch boss 6 are fixed to the lower end of the gear shaft 5, and a brake that is interlocked according to the operation of the drain valve acting solenoid (not shown) on the outer circumference of the clutch boss 6. A lever 20 is installed, and a clutch lever 23 is installed at one side of the brake lever 20 so as to interlock when the brake lever 20 is operated, and a clutch lever 23 at a lower end of the clutch lever 23. The operation cam 21 is rotated in conjunction with the operation of the installation.

이와 같이 구성된 클러치(4)는 세탁 및 탈수시 다음과 같이 작동하게 된다.The clutch 4 configured as described above operates as follows when washed and dehydrated.

먼저, 세탁시에는 배수밸브 작동겸용 솔레노이드 밸브(도시는 생략함)가 오프 상태이므로 브레이크 레버(20)의 작동으로 클러치 레버(23)가 밀리게 되고, 이에 연동하는 작동캠(21)에 클러치 보스(6)가 맞물려 클러치 스프링(9)을 직경이 증가하는 방향으로 밀게 된다.First, at the time of washing, since the drain valve actuation solenoid valve (not shown) is turned off, the clutch lever 23 is pushed by the operation of the brake lever 20, and the clutch boss is coupled to the actuating cam 21. (6) is engaged and pushes the clutch spring 9 in the direction of increasing diameter.

이에 따라, 직경이 증가한 클러치 스프링(9)은 스프링 블록(10)의 외주면으로부터 이격된 상태를 유지하게 된다.Accordingly, the clutch spring 9 having an increased diameter keeps the state spaced apart from the outer circumferential surface of the spring block 10.

따라서, 상기 모터(3)의 회전력은 V벨트(15)에 의해 클러치 풀리(14)로 전달된 후, 이에 연결된 기어 샤프트(5)로 전달되고, 다시 기어 샤프트(5) 상부에 연결 된 세탁축(16)을 통해 세탁날개(1)로 전달되어 상기 세탁날개를 회전시키게 된다.Therefore, the rotational force of the motor 3 is transmitted to the clutch pulley 14 by the V-belt 15, and then to the gear shaft 5 connected thereto, and the washing shaft connected to the upper gear shaft 5 again. It is delivered to the washing blade (1) through 16 to rotate the washing blade.

또한, 탈수시에는 세탁조(12) 내의 세탁수가 자연배수된 상태에서 배수밸브 작동겸용 솔레노이드 밸브가 동작하여 브레이크 레버(20)를 당기면 클러치 레버(23)의 연동으로 작동캠(21)이 클러치 보스(6)의 세레이션(serration)에서 이탈됨에 따라 상기 클러치 스프링(9)은 직경이 줄어들게 되며, 이때의 복원력에 의해 클러치 스프링(9)은 하부 기어 하우징(18b)과 스프링 블록(10)을 동시에 클램핑하게 하게 된다.In addition, during dehydration, when the wash water in the washing tank 12 is naturally drained, the drain valve actuation solenoid valve is operated to pull the brake lever 20 so that the actuating cam 21 is interlocked with the clutch lever 23. The clutch spring 9 is reduced in diameter as it is disengaged from the serration of 6). The clutch spring 9 clamps the lower gear housing 18b and the spring block 10 simultaneously by the restoring force. Got to be.

한편, 모터(3)의 동력을 전달받은 기어 샤프트(5)가 회전하면 기어 샤프트(5)에 고정된 스프링 블록(10)은 기어 샤프트(5)와 같이 회전을 하게 되는데, 이 때 스프링 블록(10)과 하부 기어 하우징(18b)을 클램핑하고 있는 클러치 스프링(9)은 감기는 방향으로 회전하기 때문에 더욱 강력한 클램핑 작용력을 발휘하여 미끄러지지 않고 브레이크 드럼(18a) 및 기어 유니트(19)를 회전시키게 된다.On the other hand, when the gear shaft 5 received the power of the motor 3 rotates, the spring block 10 fixed to the gear shaft 5 rotates like the gear shaft 5, at this time the spring block ( 10) and the clutch spring 9 clamping the lower gear housing 18b rotate in the winding direction, thereby exhibiting a stronger clamping force, thereby rotating the brake drum 18a and the gear unit 19 without slipping. .

따라서, 탈수시에는 모터(3)로부터 클러치(4)로 전달된 동력은 세탁축(16) 뿐만 아니라 탈수축(17)으로도 전달되어 탈수조 겸용인 세탁조(12)를 고속으로 회전시켜 탈수를 진행시키게 된다.Therefore, during dehydration, the power transmitted from the motor 3 to the clutch 4 is transmitted not only to the washing shaft 16 but also to the dehydrating shaft 17 to rotate the washing tank 12 which is a dehydrating tank at a high speed so that dehydration can be performed. Will proceed.

한편, 탈수 정지시에는 브레이크 밴드(7)가 브레이크 드럼(18a)의 외주면(181)에 밀착되어 강제 제동하여서 세탁조(12)를 정지시키게 된다.On the other hand, when the dehydration stops, the brake band 7 comes into close contact with the outer circumferential surface 181 of the brake drum 18a and is forcedly braked to stop the washing tank 12.

그러나, 상기한 바와 같이 구동장치로서 클러치를 구비한 종래의 세탁기들은 그 클러치의 구조가 매우 복잡하였으므로 제작이 어려워 생산성이 저하될 뿐만 아니라, 정밀한 부품을 많이 사용하게 되어 세탁기 제조원가가 상승하고 제작 및 작 동시 불량이나 고장이 발생할 우려가 높은 문제점이 있었다.However, as described above, the conventional washing machine having a clutch as a driving device has a complicated structure of the clutch, which is difficult to manufacture, which leads to a decrease in productivity. There was a high problem of the possibility of simultaneous failure or failure.

본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 구조가 간단하고 동작이 정확하게 이루어져 제작성을 향상시킬 수 있는 전자동 세탁기의 구동장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a driving apparatus of a full-automatic washing machine, which is simple in structure and accurate in operation, thereby improving productivity.

도 4는 상기 클러치 몸체의 형태를 나타낸 것으로, 클러치몸체(420)의 중공부 내주면에는 제 1탈수축(402) 하단부와 기어하우징(410) 상단부와 결합하는 결합돌기와 결합홈이 기어이 형태로 교대로 형성된 결합부(421)가 형성되어 있고, 상기 제 1탈수축(402) 하단부와 기어하우징(410) 외주부에는 상기 클러치몸체(420)의 결합부(421)의 결합돌기 및 결합홈에 대응하여 결합되는 대응결합부(402a, 410a)가 설치된다.Figure 4 shows the form of the clutch body, the coupling protrusion and the coupling groove coupled to the lower end of the first dehydration shaft 402 and the upper end of the gear housing 410 on the inner circumferential surface of the clutch body 420 alternately in the form of gears. A coupling part 421 is formed, and the lower part of the first dehydration shaft 402 and the outer circumference of the gear housing 410 correspond to the coupling protrusion and the coupling groove of the coupling part 421 of the clutch body 420. Corresponding coupling parts 402a and 410a are provided.

또한, 상기 클러치몸체(420)의 상단부 가장자리 부위에는 상기 클러치몸체(420)가 상측으로 이동했을 때 외조(2)에 고정되어 회전하지 않도록 원주방향으로 복수개의 고정돌기(422)가 형성되어 있으며, 상기 외조(2)에는 상기 클러치몸체(420)의 고정돌기(422)가 대응하여 결합되도록 대응고정부(427)가 형성되어 있다.In addition, a plurality of fixing protrusions 422 are formed at the upper edge portion of the clutch body 420 in the circumferential direction so that the clutch body 420 is fixed to the outer tub 2 and does not rotate when the clutch body 420 moves upward. A corresponding fixing part 427 is formed in the outer tub 2 such that the fixing protrusion 422 of the clutch body 420 is correspondingly coupled.

상기와 같이 구성된 세탁기 구동장치는 세탁 및 헹굼행정과 탈수행정시 다음과 같이 작동한다.The washing machine driving device configured as described above operates as follows when washing and rinsing and dehydrating.

먼저, 세탁 및 헹굼행정에서는 세탁조(12)는 정지된 상태에서 세탁날개(1)만이 회전하며 세탁 및 헹굼을 행하게 되는 바, 이 경우 솔레노이드(425)가 온(on)되면서 클러치몸체(420)가 상향으로 이동하여 클러치몸체(420)의 고정돌기(422)가 외조(2)의 대응고정부(427)에 결합되어 회전 방지됨과 동시에, 클러치몸체(420)의 결합부(421)는 기어하우징(410)과의 결합은 해제되면서 제 1탈수축(402)의 대응결합 부(402a, 410a)에만 결합되고, 이에 따라 기어하우징(410)은 회전이 자유로운 상태로 되고 제 1탈수축(402)은 고정되게 된다.First, in the washing and rinsing stroke, the washing tank 12 rotates only the washing blade 1 in a stopped state and performs washing and rinsing. In this case, the solenoid 425 is turned on and the clutch body 420 is turned on. The fixing projection 422 of the clutch body 420 is moved upward to prevent the rotation by being coupled to the corresponding fixing portion 427 of the outer tub 2, and the coupling portion 421 of the clutch body 420 is a gear housing ( The coupling with the 410 is released and is coupled only to the corresponding coupling portions 402a and 410a of the first dehydration shaft 402. Accordingly, the gear housing 410 is free to rotate and the first dehydration shaft 402 is It will be fixed.

이와 같은 상태에서, 모터(3)에 의해 기어하우징(410)이 회전하게 되면 내부의 선기어부(412)가 함께 회전하게 되고, 상기 제1탈수축(402)이 고정됨에 따라 제 2탈수축(403) 및 내접기어부(414)가 고정상태로 되어 있으므로 유성기어부(413)가 회전하면서 캐리어(415)가 내접기어부(414)에 대해 함께 회전하게 된다.In this state, when the gear housing 410 is rotated by the motor 3, the internal sun gear part 412 rotates together, and the second dehydration shaft (402) is fixed as the first dehydration shaft 402 is fixed. Since the 403 and the internal gear 414 are fixed, the carrier gear 415 rotates with respect to the internal gear 414 while the planetary gear 413 rotates.

따라서, 상기 캐리어(415)와 고정 결합되어 있는 세탁축(401)이 감속되면서 회전하며 세탁날개(1)를 회전시키게 되는 것이다.Therefore, the washing shaft 401 fixed to the carrier 415 is rotated while decelerating, thereby rotating the washing blade 1.

한편, 탈수행정시에는 세탁날개(1)와 세탁조(12)가 함께 회전하며 탈수를 수행하게 되게 되는데, 세탁과정에서 탈수모드가 선택되면, 솔레노이드(425)가 오프(off)되면서 클러치몸체(420)는 압축스프링(426)의 탄성력과 그의 자중에 의해 아래로 하강하게 되고, 이 때 상기 하강한 클러치몸체(420)는 제 1탈수축(402) 하단부와 기어하우징(410) 상단부를 동시에 결합시키게 된다.On the other hand, during the dehydration administration washing blade 1 and the washing tank 12 is rotated together to perform dehydration, if the dehydration mode is selected during the washing process, the solenoid 425 is off (off) clutch body 420 ) Is lowered by the elastic force of the compression spring 426 and its own weight, wherein the lowered clutch body 420 is coupled to the lower end of the first dehydration shaft 402 and the upper end of the gear housing 410 at the same time. do.

이러한 상태에서, 모터의 작동에 의해 기어하우징(410)이 회전하게 되면, 클러치몸체(420)에 의해 결합된 제 1탈수축(402) 및 이 제 1탈수축(402)에 고정된 제 2탈수축(403)이 기어하우징(410)과 동일한 속도로 회전하게 됨과 더불어, 상기 기어하우징(410) 내의 선기어부(412)와 제 2탈수축(403) 하단의 내접기어부(414)가 동일 속도로 회전함에 따라 세탁축(401) 역시 동일한 속도로 회전하며 세탁을 수행하게 된다.In this state, when the gear housing 410 is rotated by the operation of the motor, the first dewatering shaft 402 coupled by the clutch body 420 and the second dehydration fixed to the first dewatering shaft 402. As the contraction 403 rotates at the same speed as the gear housing 410, the sun gear portion 412 and the internal gear portion 414 at the lower end of the second dewatering shaft 403 in the gear housing 410 are at the same speed. As it rotates to the washing shaft 401 also rotates at the same speed to perform the washing.

한편, 전술한 실시예에서 상기 세탁축(401)은 선기어부(412)와 개별체로 되 어 캐리어(415) 및 유성기어부(413)를 매개로 회전력을 전달받도록 되어 있으나, 이와는 다르게 상기 세탁축(401)과 선기어부(412)가 일체로 구성될 수도 있다.On the other hand, in the above-described embodiment, the washing shaft 401 is a separate from the sun gear portion 412 is to receive a rotational force via the carrier 415 and the planetary gear portion 413, otherwise the washing shaft ( The 401 and the sun gear part 412 may be integrally formed.

그런데, 이 경우 상기 선기어부(412)와 유성기어부(413) 및 내접기어부(414) 자체가 감속수단으로서의 기능은 수행하지 않으므로, 세탁축(401) 및 제 1,2탈수축(402, 403)을 감속 운전하기 위해서는 상기 기어하우징(410)이 회전속도 조절이 가능한 직결식 모터의 구동축에 직접 연결되는 것이 바람직하다.However, in this case, since the sun gear 412, the planetary gear 413, and the internal gear 414 themselves do not function as a deceleration means, the washing shaft 401 and the first and second dehydration shafts 402 and 403. In order to decelerate), the gear housing 410 is preferably directly connected to the drive shaft of the direct type motor capable of adjusting the rotation speed.

또한, 상기 클러치몸체(420)의 중공부에 형성된 결합부(421)는 결합돌기와 결합홈 중 어느 하나만이 형성되어도 무방하며, 이러한 결합부의 형태는 상기 클러치몸체(420)를 제 1탈수축(402)과 기어하우징(410) 간에 이동시키면서 이들을 결합하여 줄 수 있는 임의의 형태로 구성될 수 있을 것이다.In addition, the coupling portion 421 formed in the hollow portion of the clutch body 420 may be formed of any one of the engaging projection and the coupling groove, the shape of the coupling portion of the clutch body 420, the first dehydration shaft 402 ) And the gear housing 410 may be configured in any form that can be combined to give them.

물론, 상기 클러치몸체(420)의 고정부 또한 이와 마찬가지로 외조(2)에 대해 클러치몸체(420)의 회전을 제한할 수 있는 것이라면 전술한 실시예의 고정돌기 이외에 여러가지 다양한 형태가 가능할 것이다.Of course, if the fixing portion of the clutch body 420 can also restrict the rotation of the clutch body 420 with respect to the outer shell 2 as well, various forms other than the fixing protrusion of the above-described embodiment will be possible.

이상에서와 같이 본 발명에 따르면, 기존의 클러치와 같이 복잡한 구성으로 된 구동장치를 사용하지 않고, 구동장치의 구성을 단순화함으로써 제작성이 향상되어 생산성이 증대됨과 더불어, 유지 및 보수 등의 관리가 용이하게 되는 효과가 있다.As described above, according to the present invention, without using a drive device of a complicated configuration as in the conventional clutch, by simplifying the configuration of the drive device to improve the manufacturability, productivity is increased, and maintenance and maintenance There is an effect that becomes easy.
