Description

드럼세탁기의 고정조Fixing tank of drum washing machine

본 발명은 드럼세탁기에 관한 것으로, 더욱 상세하게는 고정조의 하부에 설치되는 배수관으로 세탁수가 용이하게 흘러갈 수 있도록 하측 내면에 배수로가 형성된 고정조에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a fixing tank formed with a drainage path on the lower inner surface so that the wash water can easily flow to the drain pipe installed in the lower portion of the fixing tank.

일반적으로 드럼세탁기는 드럼형상으로 마련된 회전조의 회전으로 생긴 낙차를 이용하여 세탁물을 세탁하는 장치로, 세탁물을 빨래방망이로 두드려주는 것과 같은 효과가 발생되어 세탁효과가 크고, 세탁물의 손상이 적은 특징이 있다.In general, a drum washing machine is a device for washing laundry by using a drop generated by the rotation of a rotating tub provided in a drum shape. The drum washing machine has an effect such as tapping the laundry with a laundry bat, and thus has a large washing effect and less damage to the laundry. have.

이러한 드럼세탁기 본체에는 세탁수가 채워질 수 있도록 일측이 개구된 원통상의 고정조가 구비된다. 이 고정조는 상측에 고정조를 탄력 지지하는 현가스프링이 설치되고, 고정조의 하부에는 세탁시의 진동을 흡수하도록 고정조를 완충 지지해 주는 완충기가 설치된다.The drum washing machine body is provided with a cylindrical fixing tank of which one side is opened so that the washing water can be filled. The fixing tank is provided with a suspension gas spring for elastically supporting the fixing tank, and a lower part of the fixing tank is provided with a shock absorber that buffers the fixing tank so as to absorb vibration during washing.

고정조의 내측에는 원통상의 회전조가 설치된다. 회전조는 본체의 저부에 설치된 구동모터에 의해 구동되는데, 회전조의 후방에는 회전조를 회전시키기 위한 풀리가 설치되고, 이 풀리는 구동모터와 밸트를 매개로 연결된다. 또한, 회전조는 벽면에 다수의 탈수공이 형성되어 그 내측으로 세탁수의 유입과 유출이 자유롭게 되고, 탈수시에는 이 탈수공을 통해 세탁물에 함유된 수분이 빠져나가게 된다.A cylindrical rotating tub is provided inside the fixed tub. The rotating tub is driven by a drive motor installed at the bottom of the main body, a pulley for rotating the rotating tub is installed at the rear of the rotating tub, and the pulley is connected to the driving motor via a belt. In addition, the rotating tub is formed with a plurality of dehydration holes on the wall is free to the inflow and outflow of the wash water, the water contained in the laundry through the dehydration hole during the dehydration is released.

또한, 고정조의 하측에는 행굼과정이나 탈수과정에서 세탁수의 배수가 가능하도록 배수관이 설치되고, 배수관의 단부에는 세탁수를 강제배수 시키는 배수펌프가 설치된다.In addition, a drainage pipe is installed at the lower side of the fixing tank so that the wash water can be drained during the rinsing or dehydration process, and a drain pump for forcibly draining the wash water is installed at the end of the drainage pipe.

도 1은 종래 드럼 세탁기의 고정조에 설치되는 배수관의 결합구조를 보인 단면도이다. 이에 도시된 바와 같이, 종래의 드럼세탁기는 고정조(1)의 하단부 일측에 고정조(1)에 담수된 세탁수가 배출될 수 있도록 내측과 연통되는 배수공(2)이 형성되고, 이 배수공(2)에는 배출되는 세탁수를 외부로 안내하는 배수관(3)이 결합된다.1 is a cross-sectional view showing a coupling structure of a drain pipe installed in a fixing tank of a conventional drum washing machine. As shown in this, the conventional drum washing machine is formed with a drain hole (2) communicating with the inside so that the wash water freshened in the fixing tank (1) at one side of the lower end of the fixing tank (1), the drain hole (2 ) Is combined with a drain pipe (3) for guiding the discharged wash water to the outside.

이때, 배수공(2)은 고정조(1)에 담기는 세탁수의 배수가 용이하도록 고정조(1)의 가장 하단부에 형성된다. 배수관(3)의 상단부에는 배수관(3)이 배수공(2)에 끼워져 결합되는 동시에, 세탁수의 누출이 방지되도록 기밀구조를 형성하는 끼움홈(3a)이 형성된다.At this time, the drain hole (2) is formed at the bottom of the fixing tank (1) to facilitate the drainage of the wash water contained in the fixing tank (1). At the upper end of the drain pipe 3, the drain pipe 3 is fitted into the drain hole 2, and a fitting groove 3a is formed to form an airtight structure to prevent leakage of the wash water.

이와 같이 구성된 종래의 드럼세탁기는 세탁행정이 완료된 후, 세탁물을 헹구는 과정에서 세탁수를 교환하거나 세탁물을 탈수시킬 때 배수관(3)을 통해 세탁수를 배수시키게 된다. 특히, 탈수시에는 회전조(4)가 고속으로 회전하게 되면 세탁물에 함유되어 있는 수분이 원심력에 의해 고정조(1)쪽으로 빠지게 되고, 고정조(1)쪽으로 빠져나온 수분은 고정조(1)의 내면을 따라 하측으로 흘러 배수공(2)을 통해 배수되게 된다.The conventional drum washing machine configured as described above drains the washing water through the drain pipe 3 when the washing water is exchanged or the washing water is dewatered in the process of rinsing the laundry. In particular, during the dehydration, when the rotating tub 4 rotates at a high speed, the water contained in the laundry falls into the fixed tub 1 by centrifugal force, and the water discharged toward the fixed tub 1 is fixed tub (1). It flows downward along the inner surface of the drain through the drain (2).

그러나, 이러한 종래의 드럼세탁기는 세탁물을 탈수시키는 과정에서 회전조(4)가 고속으로 회전이 되면, 탈수공(4a)을 통해 배출되는 세탁수는 회전조(4)의 원심력에 의해 법선방향으로 날아가려는 힘과, 회전조(4)의 원주속도에 의해 접선방향으로 날아가려는 힘이 합성된 방향으로 배출되게 된다. 즉, 배출되는 세탁수는 전체적으로 회전조(4)의 회전방향으로 회전하려는 힘을 가지게되어 고정조(1)의 내면을 따라 흐르는 세탁수를 회전조(4)가 회전되는 방향으로 밀어 올리게 되어 배수를 방해하게 된다. 또한, 회전조(4)가 고속으로 회전을 하게 되면, 회전조(4)의 외면과 고정조(1)의 내면사이에는 회전조(4)를 따라 회전되는 기류가 형성되어 고정조(1)의 내면을 따라 배수공(2) 쪽으로 흐르는 세탁수의 흐름을 방해하기 때문에 배수가 원활하지 못한 문제가 있었다.However, in the conventional drum washing machine, when the rotating tank 4 is rotated at a high speed in the process of dewatering the laundry, the washing water discharged through the dewatering hole 4a is in the normal direction by the centrifugal force of the rotating tank 4. The force to fly and the force to fly in the tangential direction by the circumferential speed of the rotating tub 4 are discharged in the synthesized direction. That is, the discharged wash water has a force to rotate in the rotation direction of the rotary tub 4 as a whole, and pushes up the washing water flowing along the inner surface of the fixed tub 1 in the direction in which the rotary tub 4 rotates. Will interfere. In addition, when the rotating tub 4 rotates at a high speed, an air flow rotated along the rotating tub 4 is formed between the outer surface of the rotating tub 4 and the inner surface of the fixed tub 1 to fix the tub 1. There was a problem that the drainage is not smooth because it obstructs the flow of the wash water flowing toward the drain hole (2) along the inner surface of the.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 고정조의 하부에 형성된 배수공으로부터 회전조가 회전되는 방향으로 경사진 배수로를 형성함으로써, 탈수행정시 고정조의 내면에 흐르는 세탁수가 배수공쪽으로 용이하게 배출되게 하는 드럼세탁기의 고정조를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to form a drainage inclined in the direction in which the rotating tank is rotated from the drain hole formed in the lower portion of the fixed tank, washing water flowing in the inner surface of the fixed tank during the dehydration administration easy toward the drain hole It is to provide a fixing tank of the drum washing machine to be discharged.

이러한 구조는 탈수행정시에 고정조(20)의 내면을 따라 배수되는 물이, 회전조(13)의 고속회전으로 인해, 회전조(13)가 회전이 되는 방향으로 치우치게 되는 성질을 감안하여 회전방향쪽으로 유로를 형성한 것이다.This structure rotates in consideration of the property that the water drained along the inner surface of the fixed tub 20 during the dehydration stroke is biased in the direction in which the rotary tub 13 is rotated due to the high speed rotation of the rotary tub 13. The flow path is formed in the direction.

이를 상세히 설명하면, 세탁물을 탈수시키는 과정에서 회전조(13)가 고속으로 회전이 되면, 탈수공(13a)을 통해 배출되는 세탁수는 회전조(13)의 원심력에 의해 법선방향으로 날아가려는 힘과, 회전조(13)의 원주속도에 의해 접선방향으로 날아가려는 힘이 합성된 방향으로 배출되게 된다. 따라서, 배출되는 세탁수는 전체적으로 회전조(13)의 회전방향으로 회전하려는 힘을 가지게되어 고정조(20)의 내면을 따라 흐르는 세탁수를 회전조(13)가 회전되는 방향으로 밀어 올리게 되어 배수되는 물이 회전조(13)의 회전방향 쪽으로 치우치게 된다. 즉, 본 발명은 회전조(13)의 고속회전으로 회전방향쪽으로 치우친 물이 원활하게 배수될 수 있도록, 회전조(13)가 회전이 되는 방향쪽으로 상향 경사진 배수로(21)가 형성된다.In detail, when the rotating tub 13 is rotated at a high speed in the process of dehydrating the laundry, the washing water discharged through the dehydrating hole 13a is forced to fly in the normal direction by the centrifugal force of the rotating tub 13. And, by the circumferential speed of the rotating tank 13, the force to fly in the tangential direction is discharged in the combined direction. Therefore, the washing water discharged to have a force to rotate in the rotation direction of the rotating tub 13 as a whole to push up the washing water flowing along the inner surface of the fixed tub 20 in the direction in which the rotating tub 13 is rotated drainage The water to be rotated toward the rotation direction of the rotating tub (13). That is, in the present invention, the drainage passage 21 inclined upward toward the direction in which the rotating tub 13 is rotated is formed so that the water biased in the rotational direction can be smoothly drained by the high speed rotation of the rotating tub 13.

다음에는 이와 같이 구성된 본 발명에 따른 드럼세탁기의 작동을 설명한다.Next will be described the operation of the drum washing machine according to the present invention configured as described above.

드럼세탁기는 본체(10)의 하부에 마련된 구동모터(14)가 정방향과 역방향으로 번갈아 회전되면, 이 회전력은 밸트(15)를 통해 회전조(13)로 전달되어 회전조(13)의 회전이 이루어지게 된다. 이때, 회전조(13)의 내부에 있는 세탁물은 뒹굴거나 리프터(13b)에 의해 끌려 올라가 낙하가 되면서 세탁이 수행되게 된다.When the drum washing machine rotates alternately the driving motor 14 provided in the lower portion of the main body 10 in the forward direction and the reverse direction, the rotational force is transmitted to the rotating tank 13 through the belt 15 so that the rotation of the rotating tank 13 Will be done. At this time, the laundry inside the rotating tub 13 is rolled up or pulled up by the lifter 13b, and washing is performed.

그리고, 탈수행정 중에는 회전조(30)의 고속회전에 의해 발생되는 원심력에 의해 세탁물에 함유된 물기의 탈수가 이루어진다. 탈수된 물은 회전조(13)의 탈수공(13a)을 통해 고정조(20)쪽으로 빠져나가 고정조(20)의 하부에 연결된 배수관(30)을 통해 본체(10)의 외부로 배출되게 된다.During the dehydration stroke, the water contained in the laundry is dehydrated by the centrifugal force generated by the high speed rotation of the rotating tub 30. The dewatered water is discharged toward the fixing tank 20 through the dehydration hole 13a of the rotating tub 13 and discharged to the outside of the main body 10 through the drain pipe 30 connected to the lower portion of the fixing tub 20. .

탈수행정이 수행될 때 회전조(13)가 고속으로 회전이 되면, 탈수공(13a)을 통해 배출되는 세탁수는 상술한 바와 같이, 회전조(13)의 회전력에 의해 회전조(13)가 회전하는 방향으로 회전하려는 힘을 가지게 됨으로써, 회전방향 쪽으로 치우치게 된다. 하지만, 본 발명에 따른 드럼세탁기는 고정조(20)의 하부에 회전방향쪽으로 경사진 배수로(21)가 형성됨으로써, 회전방향으로 치우친 물이 경사진 배수로(21)를 따라 배수공(22)쪽으로 흘러 내리게되어 배수가 용이하게 이루어지게 된다.When the rotating tub 13 is rotated at a high speed when the dehydration stroke is performed, the washing water discharged through the dehydrating hole 13a is rotated by the rotational force of the rotating tub 13 as described above. By having a force to rotate in the direction of rotation, it is biased toward the direction of rotation. However, the drum washing machine according to the present invention is formed by the drainage passage inclined in the rotational direction in the lower portion of the fixing tank 20, the water biased in the rotational direction flows toward the drain hole 22 along the inclined drainage passage (21) It is lowered and drainage is made easily.

또한, 본 발명에 따른 배수로(21)는 고정조(20)의 전방으로부터 후방쪽으로 경사지게 마련됨으로써 배수효과가 더욱 높아지게 된다.In addition, the drainage passage 21 according to the present invention is provided to be inclined toward the rear from the front of the fixing tank 20 is further increased drainage effect.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 드럼세탁기는 고정조의 내측 바닥면에 함몰되게 형성되며, 고정조의 하부에 형성된 배수공으로부터 회전조가 회전되는 방향으로 상향 경사지게 형성된 배수로가 마련되었다. 따라서 탈수행정시 회전조의 회전에 의해, 회전방향 쪽으로 치우쳐 흐르는 세탁수가 상기 배수로를 통해 배수공으로 용이하게 흐르게 됨으로써 배수효과를 높이는 이점이 있다.As described above in detail, the drum washing machine according to the present invention is formed to be recessed in the inner bottom surface of the fixing tank, a drainage path formed to be inclined upward in the direction in which the rotating tank is rotated from the drain hole formed in the lower portion of the fixing tank. Therefore, by the rotation of the rotary tub during dehydration administration, washing water biased toward the rotation direction is easily flowed through the drainage path to the drain hole has the advantage of increasing the drainage effect.
