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. 그리고 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.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. And a cylindrical rotating tank is installed inside the fixed tank. 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, 상기 배수공(2)의 둘레에는 배수관(3)의 결합이 견고하게 이루어지도록, 고정조(1)의 내측 방향으로 소정의 높이 만큼 돌출되게 형성된 걸림턱(4)이 형성된다. 그리고, 배수관(3)의 단부에는 배수관(3)이 상기 걸림턱(4)에 끼워져 결합되는 동시에, 세탁수의 누출이 방지되도록 기밀구조를 형성하는 끼움홈(5)이 형성된다.At this time, the locking jaw (4) is formed around the drain hole (2) is formed to protrude by a predetermined height in the inner direction of the fixing tank (1) so that the coupling of the drain pipe (3). And, at the end of the drain pipe 3, the drain pipe 3 is fitted to the engaging jaw (4) and at the same time, a fitting groove 5 is formed to form an airtight structure to prevent leakage of the wash water.

상기 끼움홈(5)은 배수관(3)의 상단부 외주면 둘레를 따라 돌출되게 형성되는 두 개의 환턱(6,7)으로 이루어지는데, 두 개의 환턱(6,7)이 상호 이격되게 형성되어 끼움홈(5)을 이루게된다. 따라서 배수관(3)이 고정조(1)의 배수공(2)에 결합되게 되면, 상단부에 마련된 환턱(7)은 고정조(2)의 내측으로 들어가 상기 걸림턱(4)에 걸리게 되고, 하측에 마련된 환턱(6)은 고정조(1)의 외주면에 걸리게 된다.The fitting groove 5 is formed of two annular projections 6 and 7 protruding along the outer circumferential surface of the upper end of the drain pipe 3. The two recesses 6 and 7 are formed to be spaced apart from each other. 5) is achieved. Therefore, when the drain pipe 3 is coupled to the drain hole 2 of the fixing tank 1, the round jaw 7 provided at the upper end enters the inside of the fixing tank 2 and is caught by the catching jaw 4. The provided jaw 6 is caught by the outer circumferential surface of the fixing tank (1).

또한, 고정조(1)의 내측으로 진입되어 걸림턱(4)에 걸리는 상부 환턱(7)은 그 테두리부가 하측방향으로 절곡되어 연장된 절곡부(7a)가 구비되어, 걸림턱(4)을 감싸게 됨으로써, 걸림구조를 견고하게 하는 동시에 기밀구조를 이루게 된다.In addition, the upper round jaw 7 which enters the inside of the fixing tank 1 and is caught by the catching jaw 4 is provided with a bent portion 7a whose edge is bent downward and extends, so that the catching jaw 4 is closed. By being wrapped, the locking structure is firmly formed and airtight.

이러한 종래 배수관(3)의 결합구조는 고정조(1)의 배수공(2)에 배수관(3)을 결합시킬 때에는 배수관(3)의 상단부에 마련된 상부 환턱(7)이 고정조(1)의 내측으로 진입되도록 강제로 끼운다음, 고정조(1)의 내측에서 걸림턱(4)에 상부 환턱(7)의 절곡부(7a)를 씌어주게 된다.The coupling structure of the conventional drain pipe (3) has an upper annulus (7) provided at the upper end of the drain pipe (3) inside the fixing tank (1) when the drain pipe (3) is coupled to the drain hole (2) of the fixing tank (1) After forcibly inserted to enter, the bent portion (7a) of the upper round jaw (7) to the locking jaw (4) in the inside of the fixing tank (1).

그러나, 이와 같이 구성된 종래 드럼세탁기의 배수관 결합구조는 배수관(3)을 고정조의 배수공(2)에 결합시킬 때, 배수관(3)의 상단부에 마련되는 상부 환턱(7)으로 인해 결합이 어려운 문제가 있었다.However, when the drain pipe coupling structure of the conventional drum washing machine configured as described above, when the drain pipe 3 is coupled to the drain hole 2 of the fixing tank, it is difficult to couple due to the upper annulus 7 provided at the upper end of the drain pipe 3. there was.

즉, 상부 환턱(7)의 직경은 배수공(2)의 직경보다 훨씬 크기 때문에, 이를 배수공(2)에 끼울 때에는 상부 환턱(7)을 강제로 변형시켜가면서 끼워야 하기 때문에 결합시간이 많이 소요됨은 물론이고 작업이 난해한 문제가 있었다.That is, since the diameter of the upper annulus 7 is much larger than the diameter of the drainage hole 2, when it is inserted into the drainage hole 2, it is necessary to insert the upper annulus 7 while forcibly deforming the coupling time. And there was a difficult task to work.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 고정조의 배수공과 이에 결합되는 배수관의 구조를 개선하여, 결합성, 조립성, 기밀성이 우수한 배수관 결합구조를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to improve the structure of the drainage hole of the fixing tank and the drain pipe coupled thereto, to provide a drainage pipe coupling structure excellent in bondability, assembly, airtightness.

In addition, a drainage pipe 30 is installed at the lower side of the fixing tank 20 so as to enable the drainage of the wash water during the rinsing process or the dehydration process, and a drain pump 40 for forcibly draining the wash water at the end of the drainage pipe 30 is provided. Is installed.

도 3과 도 4를 참조하면, 고정조(20)의 하단부 일측에는 고정조(20)에 담수된 세탁수가 배출될 수 있도록 내측과 연통되는 배수공(21)이 형성되고, 이 배수공(21)에는 배출되는 세탁수를 외부로 안내하는 배수관(30)이 결합된다.3 and 4, at one side of the lower end of the fixing tank 20, a drain hole 21 communicating with an inner side of the washing water in the fixing tank 20 may be formed, and the drain hole 21 may be formed in the drain tank 21. The drain pipe 30 for guiding the washing water discharged to the outside is combined.

그리고, 배수관(30)의 상단부 외주면에는 골(31a)과 산(31b)으로 이루어진 나사부(31)가 형성되어, 이 나사부(31)가 상기 배수공(21)에 결합됨으로써 배수관(30)이 배수공(21)에 고정되게 된다. 즉, 본 발명에 따른 배수관(30)은 나사부(31)가 배수공(21)에 체결됨으로써 고정이 되게 된다. 이때, 배수관(30)의 단부에 형성되는 나사부(31)는 골(31a)의 간격이 고정조(20)의 두께와 일치하도록 하여, 나사부(31)가 결합될 경우 기밀구조를 형성하게 하는 것이 바람직하다.In addition, a threaded portion 31 formed of a valley 31a and a peak 31b is formed on an outer circumferential surface of the upper end of the drainage pipe 30, and the threaded portion 31 is coupled to the drainage hole 21 so that the drainage pipe 30 is drained. 21). That is, the drain pipe 30 according to the present invention is to be fixed by the screw portion 31 is fastened to the drain hole (21). At this time, the screw portion 31 formed at the end of the drain pipe 30 to match the thickness of the fixing tub 20 with the gap of the valley 31a, so that when the screw portion 31 is combined to form an airtight structure desirable.

또한, 나사부(31)는 배수관(30)의 단부쪽으로 갈수록 그 직경이 감소하는 구조로 마련되어 외면이 소정의 각도(α)만큼 경사지게 형성된다. 이는 배수관(30)을 배수공(21)에 고정시킬 때, 최초의 진입을 용이하게 하고, 배수관(30)이 진입될수록 그 직경이 커지게 됨으로써 배수공(21)과 나사부의 골(31a)이 긴밀하게 조여질 수 있도록 하기 위함이다.In addition, the screw portion 31 has a structure in which the diameter thereof decreases toward the end of the drain pipe 30 so that the outer surface is inclined by a predetermined angle α. This facilitates the initial entry when the drain pipe 30 is fixed to the drain hole 21, and the diameter thereof increases as the drain pipe 30 enters, thereby making the drain hole 21 and the valley 31a of the screw portion closely. It is intended to be tightened.

여기에서 나사부(31)는 표면이 신축성을 가지는 연질의 재질로 형성되어 배수공(21)과 나사부(31)의 밀착성을 크게 하는 것이 바람직하다.Here, the thread portion 31 is preferably formed of a flexible material having a stretchable surface to increase the adhesion between the drain hole 21 and the screw portion 31.

다음에는 이와 같이 구성된 본 발명에 따른 드럼세탁기의 작동 및 배수관의 결합방법을 설명한다.Next, the operation of the drum washing machine according to the present invention configured as described above and the coupling method of the drain pipe will be described.

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. .

한편, 본 발명에 따른 배수관(30)은 상단부 외주면에 형성된 나사부(31)가 고정조(20)에 형성된 배수공(21)에 체결됨으로써 용이하게 결합되는데, 배수관(30)을 결합시킬 때에는 나사부(31)를 배수공(21)에 끼우고 수회 돌려주면 나사부(31)의 골(31a)과 배수공(21)이 물려 강하게 조여지게 된다. 특히 나사부(31)는 표면이 신축가능한 연질의 부재로 마련되고, 외면이 경사부로 구성되기 때문에 배수관(30)을 조일수록 골(31a)의 직경이 확대되면서 긴밀하게 밀착되게 된다.On the other hand, the drain pipe 30 according to the present invention is easily coupled by fastening the screw portion 31 formed on the outer peripheral surface of the upper end to the drain hole 21 formed in the fixing tank 20, when the drain pipe 30 is coupled to the screw portion 31 ) Is inserted into the drain hole 21 and rotated several times, so that the valley 31a and the drain hole 21 of the screw part 31 are bitten tightly. In particular, since the screw portion 31 is provided with a flexible member having a stretchable surface, and the outer surface is constituted by an inclined portion, as the tightening of the drain pipe 30 is increased, the diameter of the valley 31a is in close contact with each other.

이처럼, 본 발명에 따른 배수관 결합구조는 조립성, 결합성, 기밀성을 동시에 만족할 수 있는 효과가 있다.As such, the drain pipe coupling structure according to the present invention has the effect of satisfying the assembly, bonding, airtightness at the same time.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 드럼세탁기의 배수관 결합구조는 배수관의 상단부에 외면이 경사진 나사부가 형성되고, 이 나사부가 고정조의 배수공에 체결됨으로써 배수관이 고정되게 하였다. 따라서 고정조의 하부에 형성된 배수공에 나사부를 체결하기만 하면 되므로 배수관의 결합이 간편한 이점이 있다. 특히, 나사부의 외면이 경사지게 형성됨으로써, 배수관을 배수공에 끼우기 용이할 뿐만 아니라, 나사부가 조여질수록 나사부 골의 직경이 커지게 되므로 긴밀한 결합이 이루어지는 이점이 있다.As described in detail above, the drain pipe coupling structure of the drum washing machine according to the present invention is formed with a threaded inclined outer surface at the upper end of the drain pipe, the screw is fastened to the drain hole of the fixing tank to be fixed to the drain pipe. Therefore, there is an advantage in that the coupling of the drain pipe is easy because only the screw portion is fastened to the drain hole formed in the lower portion of the fixing tank. In particular, since the outer surface of the screw portion is formed to be inclined, it is easy to fit the drain pipe into the drain hole, and as the screw portion is tightened, the diameter of the screw portion becomes larger, so that there is an advantage that a close coupling is made.
