도 2 내지 도 4를 참조하면, 본 발명의 일 실시예에 따른 드럼세탁기는 개구부가 형성된 캐비닛(50)과, 개구부 내측에 설치되어 세탁수가 담수되는 터브(52)와, 터브(52) 내측에 회전 가능하게 설치되어 세탁물이 수납되는 드럼(54)과, 터브(52)에 설치되고 드럼(54)에 연결되는 구동장치(56)와, 터브(52)로부터 캐비닛(50) 외측으로 연장되어 세탁수를 공급하는 급수장치(58)와, 터브(52)로부터 캐비닛(50) 외측으로 연장되어 세탁수를 배출하는 다중 배수장치(80)를 포함한다.2 to 4, a drum washing machine according to an embodiment of the present invention includes a cabinet 50 having an opening formed therein, a tub 52 installed inside the opening to wash water, and a tub 52 disposed inside the tub 52. A drum 54 rotatably installed to accommodate laundry, a driving device 56 installed on the tub 52 and connected to the drum 54, and extended from the tub 52 to the outside of the cabinet 50 for washing. A water supply device 58 for supplying water and a multiple drainage device 80 extending from the tub 52 to the outside of the cabinet 50 to discharge the wash water.

여기서, 다중 배수장치(80)는 터브(52)로부터 캐비닛(50) 외측으로 연장되는 배수관(81)과, 배수관(81)에 설치되는 필터(82)와, 배수관(81)으로부터 분기되어 캐비닛(50) 외측으로 연장되는 분기관(85)과, 배수관(81)과 분기관(85)에 설치되어 터브에 담수된 세탁수를 강제 배수시키는 배출수단(84)을 포함한다.Here, the multiple drainage device 80 is branched from the drain pipe 81 extending from the tub 52 to the outside of the cabinet 50, the filter 82 installed in the drain pipe 81, and the drain pipe 81. 50) a branch pipe (85) extending to the outside, and the drain pipe 81 and the branch pipe (85) is provided for discharging means 84 for forcibly draining the wash water in the tub.

이로써, 세탁작동이 종료된 후에 배수작동이 개시되면 배출수단(84)이 구동되어 배수관(81)과 분기관(83)을 통해 다량의 세탁수가 짧은 시간 동안 캐비닛(50) 외측으로 배출되도록 한다.Thus, when the drainage operation is started after the washing operation is finished, the discharge means 84 is driven to discharge a large amount of wash water to the outside of the cabinet 50 for a short time through the drain pipe 81 and the branch pipe (83).

또한 분기관(83)은 배수관(81)과 비교하여 상대적으로 낮은 위치에 배치되므로 배수관(81)에 잔존하는 세탁수가 분기관(83)을 따라 유동되어 캐비닛(50) 외측으로 배출되어 잔수의 양이 작아지는 효과가 나타난다.In addition, since the branch pipe 83 is disposed at a position relatively lower than that of the drain pipe 81, the washing water remaining in the drain pipe 81 flows along the branch pipe 83 and is discharged to the outside of the cabinet 50 so that the amount of residual water remains. This smaller effect appears.

아울러, 배출수단(84)은 배수관(81)에 설치되는 제 1 임펠러(85)와, 분기관(83)에 설치되는 제 2 임펠러(86)와, 제 1 임펠러(85)의 회전축에 연결되는 모 터(87)와, 제 2 임펠러(86)의 회전축에 설치되는 종동기어(89)와, 종동기어(89)와 기어물림되도록 모터(87)의 회전축에 설치되는 주동기어(88)를 포함한다.In addition, the discharge means 84 is connected to the first impeller 85 is installed in the drain pipe 81, the second impeller 86 is installed on the branch pipe 83, and the rotary shaft of the first impeller 85 A motor 87, a driven gear 89 installed on the rotary shaft of the second impeller 86, and a main gear 88 installed on the rotary shaft of the motor 87 to be engaged with the driven gear 89; do.

이로써, 배수작동이 개시되면 모터(87)가 구동되어 제 1 임펠러(85)가 회전되므로 배수관(81)을 통한 배수작동이 이루어지고, 모터(87)의 회전축에 설치되는 주동기어(88)와 제 2 임펠러(86)의 회전축에 설치되고 주동기어(88)와 기어물림되는 종동기어(89)에 의해 제 2 임펠러(86)가 회전되면서 분기관(83)으로의 배수가 이루어진다.As a result, when the drainage operation is started, the motor 87 is driven to rotate the first impeller 85 so that the drainage operation is performed through the drain pipe 81, and the main gear 88 installed on the rotating shaft of the motor 87. The second impeller 86 is rotated by the driven gear 89 which is installed on the rotating shaft of the second impeller 86 and is engaged with the main gear 88, thereby draining the branch pipe 83.

이렇게 2개의 관을 통해 배수가 이루어지므로 단위 시간당 배출되는 세탁수의 양이 증가되므로 배수작동에 소요되는 시간이 줄어듦을 알 수 있다.Since the drainage is made through the two pipes as described above, the amount of washing water discharged per unit time increases, so that the time required for the drainage operation is reduced.

상기와 같이 구성된 본 발명의 일 실시예에 따른 다중 배수장치 및 이를 구비하는 드럼세탁기의 작용을 살펴보면 다음과 같다.Looking at the operation of the multiple drainage device and the drum washing machine having the same according to an embodiment of the present invention configured as described above are as follows.

먼저, 드럼(54) 내부에 세탁물을 수납한 후에 세탁작동을 개시하면 급수장치(58)에 의해 터브(52)에 세탁수가 공급되고, 구동장치(56)에 의해 드럼(54)이 회전되면서 세탁작동이 이루어지게 된다.First, when the laundry operation is started after storing the laundry in the drum 54, the washing water is supplied to the tub 52 by the water supply device 58, and the drum 54 is rotated by the driving device 56 to wash the laundry. The operation is made.

이러한 세탁작동이 종료되면 배수작동이 개시되는데, 모터(87)가 구동되면 제 1 임펠러(85)가 회전되면서 터브(52)에 담수된 세탁수가 배수관(81)을 따라 캐비닛(50) 외측으로 유동된다.When the washing operation is completed, the drainage operation is started. When the motor 87 is driven, the first impeller 85 is rotated, and the wash water freshened in the tub 52 flows out of the cabinet 50 along the drain pipe 81. do.

이때, 모터(87)의 회전축에 설치되는 주동기어(88)가 기어물림된 종동기어(89)를 회전시키게 되므로 제 2 임펠러(86) 역시 회전되면서 분기관(83)을 따라 캐비닛(50) 외측으로 유동되므로 배수관 하나로 배수작동을 행할 때에 비교하여 단 위 시간당 세탁수의 배출 유량이 증가되므로 배수효율이 향상되는 효과가 나타난다.At this time, since the main gear 88 installed on the rotating shaft of the motor 87 rotates the driven gear 89 which is geared, the second impeller 86 is also rotated while the cabinet 50 is moved along the branch pipe 83. Since the flow rate increases, the discharge flow rate of the washing water per unit time increases compared to when the drainage operation is performed with one drain pipe, so that the drainage efficiency is improved.

이러한 배수작동이 종료될 무렵에는 배수관(81)에 잔수가 남게 되는데, 제 1 임펠러(85)가 잠기지 않을 정도의 작은 양의 세탁수는 배수관(81)의 하측으로 배치되는 분기관(83)을 따라 유동되어 제 2 임펠러(86)에 의해 캐비닛(50) 외측으로 배출된다.At the end of the drainage operation, the remaining water remains in the drain pipe 81. The washing water in a small amount such that the first impeller 85 is not locked is divided into the branch pipe 83 disposed below the drain pipe 81. It flows along and is discharged out of the cabinet 50 by the 2nd impeller 86. As shown in FIG.

본 발명은 도면에 도시되는 일 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art. Will understand.

또한, 다중 배수장치를 구비하는 드럼세탁기를 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 드럼세탁기에 사용되는 다중 배수장치가 아닌 다른 제품에도 본 발명의 다중 배수장치가 사용될 수 있다.In addition, the drum washing machine having multiple drainage devices has been described as an example, but this is merely exemplary, and the multiple drainage device of the present invention may be used in other products than the multiple drainage device used in the drum washing machine.

따라서 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.Therefore, the true technical protection scope of the present invention will be defined by the claims below.

상기와 같이 구성되는 본 발명에 따른 다중 배수장치 및 이를 구비하는 드럼세탁기는 분기관 및 제 2 임펠러가 설치됨으로써, 단위 시간당 배수 유량이 증가되어 배수작동에 소요되는 시간 및 비용이 절감되는 이점이 있다.The multi-drainage device and the drum washing machine having the same according to the present invention configured as described above have the advantage that the branch pipe and the second impeller are installed, thereby increasing the drainage flow rate per unit time, thereby reducing the time and cost required for the drainage operation. .

또한 본 발명은 분기관 및 임펠러 수가 증가되지만 주동기어 및 종동기어에 의해 하나의 모터로 제 1 임펠러 및 제 2 임펠러의 회전을 행하므로 증가되는 배수 유량에 비해 부품수의 증가가 이루어지지 않으므로 제품의 성능은 현저하게 향상되면서 제품 단가는 소량 증가하는 이점이 있다.In addition, the present invention increases the number of branch pipes and impellers, but since the number of parts is not increased compared to the increased drainage flow rate since the rotation of the first impeller and the second impeller with a single motor by the main gear and the driven gear While the performance is remarkably improved, the unit price increases.
