본 발명은 드럼세탁기에 관한 것으로, 특히 드럼내에 드럼의 회전방향과 반대방향으로 회전하는 회전리프트를 설치하여 세탁물을 비벼서 빠는 것과 같은 양호한 세탁효과를 얻을 수 있고 세탁물의 양이 적은 경우에도 세탁성능이 저하되거나 세탁물이 드럼에 달라 붙어 구겨지는 것을 방지할 수 있게 한 드럼세탁기에 관한 것이다. 종래에 일반적으로 사용되어온 드럼 세탁기의 구조와 작동을 첨부도면 제5도를 참조하여 설명한다.The present invention relates to a drum washing machine, and in particular, by installing a rotary lift rotating in a direction opposite to the rotational direction of the drum in the drum, it is possible to obtain a good washing effect, such as to rub the laundry to wash, even when the amount of laundry is small The present invention relates to a drum washing machine which is capable of preventing the laundry from being lowered or stuck to the drum. The structure and operation of a drum washing machine generally used in the related art will be described with reference to FIG.
드럼세탁기는 세탁물이 담겨지는 드럼(31), 드럼의 내측벽에 부착되어 세탁물을 들어을리는 역할을 하는 수개의 리프트(48), 드럼의 바깥둘레에 설치된 터브(34), 밑판(46)과 터브(34)사이에 설치되어 터브를 지지하는 수개의 댐퍼(35), 세탁물의 출입구가 되는 도어(44), 드럼의 일측면을 이루는 드럼슬라이드(32), 드럼슬라이드에 고정되어 드럼의 회전축 역할을 하는 드럼축(33), 드럼축을 지지하는 베어링하우징(36)과 베어링(37), 드럼축의 끝부분에 세레이션축(Serration Shaft)으로 끼워져 결합된 드럼풀리(38), 터브의 저면에 고정된 모터(39), 드럼풀리와 모터 풀리(40)사이에 결합되어 모터의 동력을 드럼풀리에 전달하는 벨트(41), 터브의 저면에 연결되어 세탁수를 배수시키는 역할을 하는 배수호스(42)와 배수모터(43), 터브와 아웃케이스(45)를 연결하는 도어벨로우즈(47)등으로 구성되어 있다.The drum washing machine includes a drum (31) containing laundry, several lifts (48) attached to the inner wall of the drum to lift the laundry, a tub (34) installed on the outer circumference of the drum, and a base plate (46). Several dampers 35 installed between the tubs 34 to support the tubs, doors 44 serving as doors for laundry, drum slides 32 forming one side of the drum, and fixed to the drum slides to serve as a rotating shaft of the drums. The drum shaft 33, the bearing housing 36 supporting the drum shaft, and the bearing 37, the drum pulley 38 coupled to the end of the drum shaft by a serration shaft, and fixed to the bottom of the tub. The motor 39, the belt pulley 40 is coupled between the pulley and the motor pulley 40 to transfer the power of the motor to the drum pulley, the drain hose 42 is connected to the bottom of the tub to drain the wash water ) Door bellows connecting the drainage motor (43), the tub and the outer case (45) It consists of the shoes 47 and the like.
따라서 드럼(31)내에 세탁물을 넣고 세탁기를 작동시키면 급수밸브를 통해 드럼(31)내에 물이 공급되고 일정수량이 공급된 후에는 모터(39)가 구동을 하게되며, 모터(39)의 회전력이 모터풀리(40)→벨트(41)→드럼풀리(38)→드럼축(33)→드럼슬라이더(32)를 통해 드럼(31)에 전달되어 드럼이 회전을 하게 된다. 또 드럼(31)이 회전을 하면 드럼내의 세탁물이 드럼 내주벽에 설치된 리프트(48)에 의해 상방으로 들어올려졌다가 하방으로 낙하는 작동을 반복하게되며, 낙하시의 충격력에 의해 세탁이 된다.Therefore, when the laundry is put in the drum 31 and the washing machine is operated, after the water is supplied to the drum 31 through the water supply valve and a predetermined amount of water is supplied, the motor 39 is driven, and the rotational force of the motor 39 The motor is pulled through the belt 40, the belt 41, the drum pulley 38, the drum shaft 33, the drum slider 32, and the drum rotates. When the drum 31 rotates, the laundry in the drum is lifted upward by the lift 48 provided on the drum inner circumferential wall, and then drops downward. The laundry is washed by the impact force during the fall.
이렇게 세탁작용이 진행되는 동안에는 드럼(31)이 저속(약 50-55회전/분)으로 정·역방향의 회전을 반복하게 되고 탈수시에는 고속(약 800-1000회전/분)으로 회전을 하게되며, 탈수되는 물은 드럼(31) 원주벽에 형성된 수많은 미세한 구멍(도시는 생략함)을 통해 터브(34)로 빠져나온후 배수호스(42)를 거쳐 배수펌프(43)에 의해 밖으로 배수된다. 그러나 상기한 바와 같은 종래의 드럼세탁기는 세탁시 세탁물이 리프트(48)에 의해 들어올려져 상방으로 이동하였다가 정점부분에서 아래로 떨어지면서 세탁수에 부딪치는 충격력에 의해서만 세탁이 되는 구조이어서 찌든때나 심하게 오염된 세탁물은 세탁이 잘되지 않으며, 또한 세탁물의 양이 적은 경우에는 세탁물이 드럼(3)의 내벽에 밀착된 상태로 잘떨어지지 않아 세탁효과가 저하됨은 물론 탈수가 완료된 후에도 세탁물이 구겨져 있는 현상이 발생하는 등의 문제점이 있다.During this washing operation, the drum 31 rotates in the forward and reverse directions at a low speed (about 50-55 revolutions / minute) and rotates at a high speed (about 800-1000 revolutions / minute) when dewatering. The dewatered water exits the tub 34 through a number of fine holes (not shown) formed in the circumferential wall of the drum 31 and is drained out by the drain pump 43 through the drain hose 42. However, in the conventional drum washing machine as described above, when the laundry is lifted by the lift 48 and moved upward, the drum washing machine is washed only by the impact force that strikes the washing water while falling down from the peak part. The heavily contaminated laundry does not wash well, and if the amount of the laundry is small, the laundry does not fall well in close contact with the inner wall of the drum (3), which lowers the washing effect and wrinkles the laundry even after dehydration is completed. There is a problem such as this occurs.
본 발명은 드럼내부에 드럼의 회전방향과 반대방향으로 회전하는 리프트를 설치하고 드럼의 내벽면을 요철형상으로 형성하여 세탁물이 리프트와 드럼내벽면 사이에서 두드려빠는 것과 세탁될 수 있게 한 것인바, 이를 첨부된 도면 제1도 내지 제4도에 의해 더욱 상세하게 설명하면 다음과 같다.The present invention is to install a lift that rotates in the drum in the opposite direction to the drum rotational direction and to form the inner wall surface of the drum in the concave-convex shape so that laundry can be washed between the lift and the drum inner wall surface, This will be described in more detail with reference to FIGS. 1 to 4 as follows.
첨부도면 제1도와 제2도는 본 발명을 나타낸 드럼세탁기의 전체 단면도와 축연결부분의 단면도로서 드럼(1), 터브(4), 터브와 밑판(16)사이에 설치된 댐퍼(5), 도어(14), 드럼슬라이더(2), 드럼축(3). 베이링하우징(6), 베어링(7), 드럼풀리(8), 모터(9), 모터풀리(10), 벨트(11), 배수호스(12), 배수모터(13), 아웃케이스(15)와 도어(14)사이에 연결된 도어벨로우즈(17), 백카버(18)에 설치된 급수밸브(1)와 배수구(20)등의 기본구조는 종래의 드럼세탁기와 같다.1 and 2 are a cross-sectional view of the drum washing machine according to the present invention, and a sectional view of a shaft connecting portion, and a damper 5 and a door installed between the drum 1, the tub 4, the tub and the bottom plate 16, respectively. 14), drum slider (2), drum shaft (3). Bearing housing (6), bearing (7), drum pulley (8), motor (9), motor pulley (10), belt (11), drain hose (12), drain motor (13), outer case (15) ) And the door bellows 17 connected between the door 14 and the water supply valve 1 and the drain port 20 installed in the back cover 18 are the same as the conventional drum washing machine.
드럼(1)의 내주벽 가까이에는 수개의 로울러리프트(21)가 드럼의 폭 방향으로 설치되어 있고 각 로울러리프트(21)에는 제4도와 같이 세탁물이 로울러 리프트에 감기는 것을 방지하기 위한 리프트카버(22)가 결합되어 있다.Several roller lifts 21 are provided in the width direction of the drum near the inner circumferential wall of the drum 1, and each roller lift 21 has a lift cover for preventing the laundry from being wound on the roller lift as shown in FIG. 22) is combined.
또 드럼축(3)은 가운데가 공간인 중공축으로 되어 있고 그 공간부에는 리프트축(23)이 삽입되어 있으며, 리프트축(23)에는 일체형의 리프트댐퍼(24)가 형성되어 있고 이 리프트댐퍼(24)의 끝부분에는 제4도와 같이 리프트카버(22)가 스프링(25)에 의해 탄력적으로 결합되어 있다.The drum shaft 3 is a hollow shaft having a space in the center thereof, and a lift shaft 23 is inserted into the space portion, and the lift shaft 23 is formed with an integrated lift damper 24, which is a lift damper. At the end of 24, the lift cover 22 is elastically coupled by the spring 25 as shown in FIG.
따라서 로울러리프트(21)는 탄력적으로 승강 가능하다. 리프트축(23)의 끝부분에는 리프트풀리(26)가 세레이션축으로 결합되어 있다.Therefore, the roller lift 21 can be elastically lifted and lowered. The lift pulley 26 is coupled to the end of the lift shaft 23 by the serration shaft.
리프트풀리(36)의 직경은 드럼풀리(8)의 직경보다 작게 형성되고 리프트풀리(26)의 외주면과 드럼풀리(8)의 내주면에 각각 치차가 형성되어 있으며, 이들 풀리(8)(26)사이에는 제2도 및 제3도와 같이 솔레노이드(28)에 의해 전,후진 운동이 가능한 중간기어(27)가 설치되어 있다.The diameter of the lift pulley 36 is smaller than the diameter of the drum pulley 8, and gears are formed on the outer circumferential surface of the lift pulley 26 and the inner circumferential surface of the drum pulley 8, respectively, and these pulleys 8 and 26 are formed. Intermediate gears 27 capable of forward and backward movements are provided by the solenoids 28 as shown in FIGS. 2 and 3.
따라서 제2도의 실선도시와 같이 중간기어(27)가 전진하여 드럼풀리(8)와 리프트풀리(26)사이에 결합된 상태에서는 드럼풀리(8)의 회전력이 중간기어(27)를 통해 리프트풀리(26)에 전달되고 일점쇄선도시와 같이 중간기어(27)가 후진한 상태에서 드럼풀리(8)의 회전력이 리프트풀리(26)에 전달되지 않는다. 또한 드럼(1)의 원주벽은 제4도와 같이 요철면(1a)으로 형성되어 있다.Therefore, as shown in the solid line of FIG. 2, when the intermediate gear 27 is advanced and coupled between the drum pulley 8 and the lift pulley 26, the rotational force of the drum pulley 8 is lifted through the intermediate gear 27. The rotational force of the drum pulley 8 is not transmitted to the lift pulley 26 in the state in which the intermediate gear 27 is reversed as shown in the dashed-dotted line. Moreover, the circumferential wall of the drum 1 is formed in the uneven surface 1a like FIG.
상기와 같이된 본 발명 드럼세탁기에 의해 세탁물을 세탁하는 작동을 설명한다.The operation of washing the laundry by the drum washing machine of the present invention as described above will be described.
먼저 세탁기의 작동전 상태에서는 제2도의 실선도시와 같이 중간기어(27)가 드럼풀리(8)와 리프트풀리(26)사이에 결합되어 있게 된다. 이 상태에서 세탁기를 작동시키면 드럼(1)내에 물이 공급되고 모터(9)의 회전력이 모터풀리(10)→벨트(11)→드럼풀리(8)→드럼축(3)→드럼슬라이더(2)를 거쳐 드럼(1)에 전달되어 드럼(1)이 회전하는 한편, 드럼풀리(8)의 회전력이 중간기어(27)를 통해 리프트풀리(26)에 전달되어 리프트축(23), 리프트댐퍼(24), 리프트카버(22), 로울러리프트(21)가 함께 회전하게 된다.First, in the pre-operation state of the washing machine, the intermediate gear 27 is coupled between the drum pulley 8 and the lift pulley 26 as shown in the solid line of FIG. 2. When the washing machine is operated in this state, water is supplied into the drum 1, and the rotational force of the motor 9 is changed from the motor pulley 10 to the belt 11 to the drum pulley 8 to the drum shaft 3 to the drum slider 2 The drum 1 rotates while the drum 1 rotates, while the rotational force of the drum pulley 8 is transmitted to the lift pulley 26 through the intermediate gear 27 to lift the lift shaft 23 and the lift damper. The 24, the lift cover 22, and the roller lift 21 rotate together.
이때 드럼풀리(8)의 회전력이 중간기어(27)를 통해 리프트풀리(26)에 전달되므로 리프트풀리(26)는 드럼 풀리(8)와 반대방향의 회전을 하게 되며, 이러한 리프트풀리(26)의 반대방향 회전에 따라 로울러리프트(21) 역시 드럼(1)의 회전방향과 반대방향으로 회전하게 된다.At this time, since the rotational force of the drum pulley 8 is transmitted to the lift pulley 26 through the intermediate gear 27, the lift pulley 26 rotates in the opposite direction to the drum pulley 8, and the lift pulley 26 The roller lift 21 also rotates in a direction opposite to the rotation direction of the drum 1 according to the opposite direction of rotation.
따라서, 제4도와 같이 세탁물이 드럼(1)의 내측벽을 따라 회전하면서 드럼(1)의 요철면(1a)과 로울러리프트(21)사이로 통과하게 되는데, 로울러리프트(21)는 스프링(25)에 의해 드럼의 내측벽 방향으로 밀리는 힘을 받고 있으므로 세탁물은 로울러리프트(21)를 통과할때 드럼의 요철면(1a)쪽으로 압축되고 이에 따라 세탁물을 두드려빠는 것과 같은 효과를 얻을 수 있게 되는 것이다.Therefore, as shown in FIG. 4, the laundry passes along the inner wall of the drum 1 and passes between the uneven surface 1a of the drum 1 and the roller lift 21. The roller lift 21 is a spring 25. Since the laundry is pushed in the direction of the inner wall of the drum, the laundry is compressed toward the uneven surface 1a of the drum when passing through the roller lift 21, and thus the effect of tapping the laundry can be obtained.
또한 로울러리프트(21)에 리프트카버(22)가 결합되어 세탁물은 로울러리프트(21)에 감기지 않고 로울러리프트(21)와 드럼내측벽요철면(1a)사이로 원활하게 통과된다. 그리고 세탁행정이 끝나고 탈수행정이 시작되면 제2도의 일점쇄선 도시와 같이 전원이 인가된 솔레노이드(28)에 의해 중간기어(27)가 후진하여 드럼풀리(8)와 리프트풀리(26)사이에서 빠져나오게 되고 이에 따라 모터(9)의 구동력에 의해 드럼풀리(8)가 회전할때 그 회전력이 리프트풀리(26)에는 전달되지 않으므로 드럼(1)과 로을러리프트(21)사이에 끼인 세탁물의 마찰력에 의해 로울러리프트(21)는 드럼(1)과 같은 방향으로 회전을 하게 된다.In addition, the lift carber 22 is coupled to the roller lift 21 so that the laundry passes smoothly between the roller lift 21 and the drum inner wall uneven surface 1a without being wound around the roller lift 21. When the washing stroke is finished and the dehydration stroke is started, the middle gear 27 is retracted by the solenoid 28 applied with power as shown in the dashed-dotted line of FIG. 2 to fall out between the drum pulley 8 and the lift pulley 26. When the drum pulley 8 is rotated by the driving force of the motor 9, the rotational force is not transmitted to the lift pulley 26, so the friction force of the laundry pinched between the drum 1 and the laurel lift 21. By the roller lift 21 is rotated in the same direction as the drum (1).
또한 탈수행정이 종료된 후 솔레노이드(28)의 전원이 차단되고 중간기어(27)가 다시 드럼풀리(8)와 리프트풀리(26)사이에 결합되며, 이때 모터(9)를 구동시키면 드럼(1)과 로울러리프트(21)가 서로 반대방향의 회전을 하여 드럼(1)의 내측벽에 달라붙어 구겨진 세탁물을 펴주게 된다.In addition, the power of the solenoid 28 is cut off after the dehydration stroke is completed, and the intermediate gear 27 is coupled between the drum pulley 8 and the lift pulley 26 again, and when the motor 9 is driven, the drum 1 ) And the roller lift 21 are rotated in opposite directions to straighten the crumpled laundry stuck to the inner wall of the drum (1).
이상에서와 같이 본 발명은 드럼내에 드럼과 반대방향으로 회전하는 로울러리프트를 설치하여 세탁물을 두드려빠는 것과 같이 세탁할 수 있으므로 세탁효율의 향상을 가져오게되고 탈수후에는 구겨진 세탁물을 편상태로 꺼낼 수 있게 되는 효과가 있다.As described above, the present invention can install the roller lift in the drum to rotate in the opposite direction to the drum can be washed like tapping the laundry, thereby improving the washing efficiency, and after dehydration can take out the crumpled laundry in a flat state It is effective to be.
