Is formed.

상기 같이 구성된 세탁기의 작용를 설명하는 다음과 같다.The following describes the operation of the washing machine configured as described above.

먼저, 세탁시에는 원하는 세탁조건을 선택하여 전원을 인가하면, 세탁겸탈수조(6)내로 적정량의 세탁수가 공급되고, 세탁수 공급이 완료된 후에 외조(2)의 중심 하단에 설치된 모터(31)가 작동하게 된다.First, when washing is selected when the desired washing conditions are applied, the appropriate amount of washing water is supplied into the washing and dehydration tank (6), and after the washing water supply is completed, the motor (31) installed in the lower center of the outer tub (2) Will work.

이에 제2도에 도시한 바와 같이, 모터(31) 작동으로 모터축(32)이 고속 회전하게 되면서, 상기 모터축(32)의 하단에 기어맞춤된 다수개의 유성기어(42)가 회전하게 되고, 상기 유성기어(42)의 중심축(42a)에 연결된 하부캐리어(44)가 회전하게 되며서 상기 하부캐리어(44)의 중심에 세레이션 형식에 의해 결합된 세탁축(11)이 회전하게 된다.2, the motor shaft 32 is rotated at high speed by the operation of the motor 31, so that a plurality of planetary gears 42 geared to the lower end of the motor shaft 32 is rotated. When the lower carrier 44 connected to the central axis 42a of the planetary gear 42 rotates, the laundry shaft 11 coupled to the center of the lower carrier 44 by the serration type is rotated. .

이때, 상기 캠레버(51)의 하축에 연동회전하는 기어레버(55)에 의해 그와 기어맞춤된 제1캠(56)이 일정 반경 회전하게 되고, 이에 따라 제1캠(56)의 가이드부가 제2캠(57)의 가이드홈을 따라 이동됨과 아울러 상기 제2캠(57)의 내측에 압축되어 있던 코일스프링(58)의 탄발력에 의해 제2캠(57)이 제1캠(51)의 가이드부와 미끄럼접촉하면서 하측으로 이동게 되며, 이에 따라 제2캠(57)의 일측부가 상기한 내접기어(41)의 삽입홈(41a)에 삽입되어 내접기어(41)의 회전을 구속하게 된다.At this time, the first cam 56 geared thereto by the gear lever 55 which is interlocked with the lower axis of the cam lever 51 is rotated by a predetermined radius, and thus the guide portion of the first cam 56 The second cam 57 is moved along the guide groove of the second cam 57 and the second cam 57 is driven by the elastic force of the coil spring 58 that is compressed inside the second cam 57. The lower portion of the second cam (57) is inserted into the insertion groove (41a) of the internal gear 41 to restrain the rotation of the internal gear (41). do.

따라서, 제2캠(57)의 구속에 의해 내접기어(41)가 고정되어 회전하지 않기 때문에 상기한 유성기어(42)와 하부캐리어(44)에 의한 감속이 이루어져 상기 세탁축(11)이 감속된 회전속도로 회전하게 되고, 이에 따라 세탁축(11)에 연결된 교반수단(7)이 좌우 반전되면서 세탁을 행하게 된다.Therefore, since the internal gear 41 is not fixed and rotated by the restraint of the second cam 57, the above-described planetary gear 42 and the lower carrier 44 are decelerated, and the washing shaft 11 is decelerated. The rotating speed is rotated, and the washing means 11 connected to the washing shaft 11 is reversed left and right to wash.

한편, 상기한 동작이 수행됨과 더불어, 상기한 캠레버(51)의 작동에 의해 캠(51a)이 회전하여 상기한 클러치레버(52)가 힌지(52a)를 중심으로 시이소 운동하게되고, 이에 클러치레버(52)의 일측에 연결된 상부클러치(53)가 상측으로 이동하게 되면서 하부클러치(54)와의 맞물림 결합이 해제되어 모터의(31)의 동력이 탈수축(12)에는 전달되지 않게 된다.On the other hand, the above-described operation is performed, the cam 51a is rotated by the operation of the cam lever 51 so that the clutch lever 52 is seesaw movement around the hinge 52a, thereby clutch As the upper clutch 53 connected to one side of the lever 52 moves upward, the engagement with the lower clutch 54 is released, so that the power of the motor 31 is not transmitted to the dehydration shaft 12.

상기와 같이 세탁이 수행된 후 일정시간이 지나 세탁이 완료되면, 세탁수의 배수가 이루어지고 수회의 헹굼이 행하여지고 나서 탈수행정이 시작된다.After the washing is performed as described above, when the washing is completed after a predetermined time, the drainage of the washing water is made and several rinsing is performed, and then the dehydration process is started.

이렇게 탈수행정이 시작되면, 제3도에 도시한 바와 같이, 상기한 캠레버(51)의 작동에 의해 캠(51a)이 회전하면서 클러치레버(52)가 힌지(52a)를 중심으로 시이소 운동하게 되고, 이에 클러치레버(52)의 일측에 연결된 상부클러치(53)가 하측으로 이동하게 되면서 하부클러치(54)와 맞물리게 되며, 이에 상기 상부클러치(53)의 내주면에 세레이션 형식에 의해 결합된 탈수축(12)이 모터축(32)의 회전을 전달받을 수 있게 된다.When the dehydration stroke starts in this way, as shown in FIG. 3, the cam lever 51 is rotated by the operation of the cam lever 51 so that the clutch lever 52 moves on the hinge 52a around the hinge 52a. As the upper clutch 53 connected to one side of the clutch lever 52 moves downward, the upper clutch 53 is engaged with the lower clutch 54, thereby being detached and coupled to the inner circumferential surface of the upper clutch 53 by a serration type. The contraction 12 is able to receive the rotation of the motor shaft 32.

따라서, 모터축(32)이 고속회전하게 되면, 탈수축(12)이 고속회전하게 되고, 이에 탈수축(12)에 연결된 세탁겸탈수조(6)가 고속회전하여 탈수를 행하게 된다.Therefore, when the motor shaft 32 rotates at high speed, the dehydration shaft 12 rotates at high speed, and the washing and dewatering tank 6 connected to the dewatering shaft 12 rotates at high speed to perform dehydration.

한편, 상기한 바와 같이, 모터(31)가 작동하여 모터축(32)이 고속회전 하게 되면, 모터축(32) 하단에 기어맞춤된 다수개의 유성기어(42)가 회전하게 되는 바, 이때, 상기 캠레버(51)의 하측에 연동회전하는 기어레버(55)에 의해 그와 기어맞춤된 제1캠(56)이 일정 반경 회전하게 되고, 이에 따라 제1캠(56)의 가이드부가 제2캠(57)의 가이드홈을 따라 이동하게 되면서 상기 제2캠(57)이 내측면의 코일스프링(58)을 압축함과 아울러 제1캠(51)의 가이드부와 미끄럼접촉하면서 상측으로 이동하게 되어 상기 제2캠(57)이 내접기어(41)의 삽입홈(41a)에서 이탈하게 되며, 이에 내접기어(41)의 고정이 해제되어 상기한 유성기어(42)의 회전에 따라 내접기어(41)가 함께 회전하게 된다.On the other hand, as described above, when the motor 31 is operated to rotate the motor shaft 32 at high speed, a plurality of planetary gears geared to the lower end of the motor shaft 32 is rotated, in this case, The first cam 56 geared thereto is rotated by a gear lever 55 which is interlocked on the lower side of the cam lever 51 so that the guide portion of the first cam 56 is secondly rotated. While moving along the guide groove of the cam 57, the second cam 57 compresses the coil spring 58 of the inner side, and slides upwardly while slidingly contacting the guide portion of the first cam 51. Thus, the second cam 57 is separated from the insertion groove 41a of the internal gear 41, and the internal gear 41 is released from the internal gear 41 according to the rotation of the planetary gear 42. 41) will rotate together.

따라서, 내접기어(41)가 고정이 해제되어 회전하기 때문에 유성기어(42)와 하부캐리어(44)에 의한 세탁축(11)의 감속은 이루어지지 상태로, 감속수단(4)의 공회전에 따라 세탁축(11)이 회전함과 더불어 탈수축(12)에 연결된 세탁겸탈수조(6)가 회전하면서 탈수를 행하게 된다.Therefore, since the internal gear 41 is released by rotation, the deceleration of the washing shaft 11 by the planetary gear 42 and the lower carrier 44 is not performed, and according to the idling of the deceleration means 4. As the washing shaft 11 rotates, the washing and dewatering tank 6 connected to the dehydrating shaft 12 rotates to perform dehydration.

그러나, 상기와 같이 탈수행정시에 탈수축(12)과 세탁축(11)이 회전함에 있어서, 상기 탈수축(12)은 모터(31)의 회전 동력을 직접 전달받게 되어 탈수축(12)에 연결된 세탁겸탈수조(6)도 모터(31)의 회전속도와 동일한 회전속도로 회전하게 되고, 상기 세탁축(11)은 모터(31)의 회전동력을 직접 전달되지 않고 다만 감속수단(4)의 공회전에 따라 회전하게 되므로, 이 세탁축(11)에 연결된 교반수단(7)의 회전속도가 세탁겸탈수조(6)의 회전속도보다 떨어지게 된다.However, when the dehydration shaft 12 and the washing shaft 11 are rotated during the dehydration stroke as described above, the dehydration shaft 12 receives the rotational power of the motor 31 directly to the dewatering shaft 12. The connected washing and dehydration tank 6 is also rotated at the same rotational speed as the rotational speed of the motor 31, the washing shaft 11 is not directly transmitted to the rotational power of the motor 31, but the deceleration means (4) Since it rotates according to the idling, the rotational speed of the stirring means (7) connected to the washing shaft 11 is lower than the rotational speed of the washing and dehydration tank (6).

즉, 탈수행정시에 세탁겸탈수조(6)와 교반수단(7)의 회전수가 동일하지 못하여 세탁물에 손상을 가져오게 되는 문제점이 있었다.That is, the rotation speed of the washing and dehydrating tank 6 and the stirring means 7 at the time of dehydration administration was not the same, there was a problem that causes damage to the laundry.

본 발명은 탈수행정시에 상기 세탁겸탈수조(6)와 교반수단(7)이 동일한 회전수로 회전할 수 있도록 상기 교반수단(7)의 중앙하부 내측 빈공간에 구비됨과 아울러 세탁수의 수위에 따라 상·하로 움직이며 상기 교반수단(7)과 세탁겸탈수조(6)를 단속하는 부력부재(100)와, 탈수행정시에 상기 부력부재(100)가 삽입 고정될 수 있도록 상기 탈수축(12)과 세탁겸탈수조(6)를 연결하는 플랜지(110)의 일측부에 형성된 연결홈(110a)으로 이루어져 있다.The present invention is provided in the empty space inside the central lower portion of the stirring means (7) so that the washing and dehydration tank (6) and the stirring means (7) can rotate at the same rotational speed during dehydration administration and the water level of the wash water. Buoyancy member 100 to move up and down in accordance with the stirring means (7) and the washing and dehydration tank (6), and the dewatering contraction so that the buoyancy member 100 can be inserted and fixed in the dehydration administration 12 consists of a connecting groove (110a) formed on one side of the flange 110 for connecting the washing and dehydration tank (6).

여기서, 상기 부력부재(100)를 상기 교반수단(7)의 중앙하부 내측 빈공간에 삽입함에 있어서, 상기 빈공간의 상황에 따라 다수개를 삽입할수 있다.Here, in inserting the buoyancy member 100 into the lower space inside the center of the stirring means 7, a plurality of the buoyancy member 100 can be inserted according to the situation of the empty space.

즉, 부력부재(100)가 회전시에 교반수단(7)의 하부를 간섭하지 않는 조건이 된다면, 세탁겸탈수조(6)와 교반수단(7)의 단속을 보다 효과적으로 할 수 있도록 다수개의 부력부재(100)를 삽입 사용할 수 있는 것이다.That is, if the buoyancy member 100 is a condition that does not interfere with the lower portion of the stirring means (7) during rotation, a plurality of buoyancy to more effectively control the washing and dehydration tank (6) and the stirring means (7) The member 100 can be inserted and used.

따라서, 상기와 같은 본 발명의 작동 및 그 효과를 도 4 및 도 5를 참조하여 설명하면 다음과 같다.Therefore, the operation and effects of the present invention as described above with reference to Figures 4 and 5 as follows.

먼저, 세탁행정시에 세탁조건을 선택하여 전원을 인가하게 되고, 이에 세탁겸탈수조(6)내로 적정량의 세탁수가 공급되면, 상기한 부력부재(100)가 세탁수의 부력에 의해 교반수단(7) 중앙하부 빈 공간의 측면벽을 따라 상부로 이동하게 되고, 이에 따라 세탁겸탈수조(6)와 교반수단(7)의 부력부재(100)에 의해 연결은 해제되게 된다.First, power is applied by selecting washing conditions at the time of washing administration, and when appropriate amount of washing water is supplied into the washing and dewatering tank 6, the buoyancy member 100 is stirred by the buoyancy force of the washing water ( 7) is moved upward along the side wall of the central lower empty space, and thus the connection is released by the buoyancy member 100 of the washing and dehydrating tank 6 and the stirring means 7.

As the seesaw movement to the upper clutch 53 connected to one side of the clutch lever 52 is moved to the lower side to engage the upper clutch 53 and the lower clutch 54 bound to the motor shaft 32. Accordingly, the dehydration shaft 12 coupled to the inner circumferential surface of the upper clutch 53 by the serration type receives the rotation of the motor shaft 32, so that the dehydration shaft 12 rotates at a high speed and is detached. The washing and dewatering tank 6 connected to the contraction 12 rotates at a high speed to perform dehydration.

더불어, 상기한 바와 같이, 부력부재(11)에 의해 세탁겸탈수조(6)와 연결된 교반수단(7)도 세탁겸탈수조(6)와 동일한 회전속도로 회전하면서 탈수를 행하게 된다.In addition, as described above, the stirring means (7) connected to the washing and dewatering tank (6) by the buoyancy member (11) also spins at the same rotational speed as the washing and dewatering tank (6).

이와 같이, 본 발명에 의하면 탈수행정시에 세탁겸탈수조(6)와 교반수단(7)이 동일한 회전수로 회전하게 됨으로써, 세탁물의 손상을 막을 수 있게 되는 것이다.As described above, according to the present invention, the washing and dewatering tank 6 and the stirring means 7 rotate at the same rotation speed during the dehydration operation, thereby preventing damage to the laundry.
