The cold water hose 7a is provided with a cold water valve 11a for circulating or interrupting the supply of cold water, and the hot water valve 11b is provided for the coma hose 7b for circulating or blocking the supply of hot water.

또한, 하우징(1)의 내측 상부에는 회전조(3)에 세제를 공급하는 세제용기(8)가 설치된다. 상기한 냉수호스(7a)와 온수호스(7b)는 세제용기(8)에 각각 연결되어 세제용기(8)를 경유하여 회전조(3) 내에 냉수 또는 온수를 공급하게 된다.In addition, a detergent container 8 for supplying detergent to the rotating tank 3 is installed at an inner upper portion of the housing 1. The cold water hose 7a and the hot water hose 7b are respectively connected to the detergent container 8 to supply cold water or hot water to the rotary tank 3 via the detergent container 8.

또한, 하우징(1)의 내측 하부에는 하우징(1)의 외부로 세탁수를 배출시키기 위한 배수호스(9)와, 고정조(2) 내의 세탁수를 펌핑하여 배수호스(9)를 통해 외부로 배출시키는 배수펌프(10)가 설치되어 있다.In addition, a drain hose 9 for discharging the wash water to the outside of the housing 1 and pumping the wash water in the fixing tank 2 to the inner lower portion of the housing 1 to the outside through the drain hose (9). A drain pump 10 for discharging is provided.

상기한 구성을 갖는 드럼세탁기의 작동은 구동모터(5)의 구동력에 의해 회전조(3)를 회전시켜 세탁행정, 헹굼행정, 그리고, 탈수행정을 수행하게 된다. 이때, 각 행정시 배수가 실시되며, 배수는 배수펌프(10)의 강제 펌핑에 의하여 고정조(2) 내부의 세탁수를 배수호스(9)를 통하여 외부로 배출하게 된다.The operation of the drum washing machine having the above-described configuration rotates the rotary tub 3 by the driving force of the driving motor 5 to perform washing, rinsing, and dehydrating strokes. At this time, the drainage is carried out during each stroke, the drainage is discharged to the outside through the drain hose (9) by the forced pumping of the drain pump (10).

도 2에 도시된 바와 같이, 본 발명의 실시예에 따른 드럼세탁기는 전반적인 제어를 수행하는 제어부(30)를 구비한다.As shown in Figure 2, the drum washing machine according to the embodiment of the present invention includes a control unit 30 for performing overall control.

이 제어부(30)의 입력측에는 세탁조(4) 내의 세탁수의 수위를 검출하는 수위검출센서(31)가 전기적으로 연결된다.The water level detection sensor 31 which detects the water level of the wash water in the washing tank 4 is electrically connected to the input side of this control part 30.

이 제어부(30)의 출력측에는 냉수호스(7a)에 설치된 냉수밸브(11a)와 온수호스(7b)에 설치된 온수밸브(11b)를 구동시키는 밸브구동부(33)와, 구동모터(5)를 구동시키는 모터구동부(34)와, 배수펌프(10)를 구동시키는 펌프구동부(35가 전기적으로 연결된다.On the output side of this control part 30, the valve drive part 33 which drives the cold water valve 11a provided in the cold water hose 7a, and the hot water valve 11b provided in the hot water hose 7b, and the drive motor 5 are driven. The motor driving unit 34 and the pump driving unit 35 for driving the drainage pump 10 are electrically connected.

상기한 제어부(30)는 세탁행정, 헹굼행정 또는 최종 탈수행정시, 배수 후 탈수를 수행하여 구동모터(5)를 통해 세탁조(4)를 고속 회전시켜 세탁물을 탈수시킴과 함께 배수펌프(10)를 구동하여 세탁물에서 배출된 물을 펌핑하여 배수호스(9)를 통해 배출한다.The control unit 30 performs the dehydration after draining during washing, rinsing, or final dehydration stroke, and rotates the washing tank 4 at high speed through the driving motor 5 to dehydrate the laundry and drain pump 10. By driving the pumped water discharged from the laundry is discharged through the drain hose (9).

이때, 상술한 바와 같이, 탈수에 의해 발생되어 세탁조(4) 내에 배수되지 않고 남아 있는 탈수량이 배수펌프(10)의 펌핑에 의해 배출되는 물량이상으로 다량 발생되면, 배수호스(9)를 통해 원활히 배출되지 못하여 배수에러가 발생할 수 있으며, 심한 경우에는 배수펌프(10)에 과부하를 유발하여 과전류로 인해 배수펌프(10)가 손상될 우려가 있다.At this time, as described above, if the amount of dehydration generated by dehydration and remaining without being drained in the washing tank 4 is discharged by the pumping of the drainage pump 10, a large amount is generated through the drain hose 9. It may not be discharged smoothly, a drainage error may occur, and in severe cases, the drainage pump 10 may be overloaded to damage the drainage pump 10 due to overcurrent.

이를 위해 도 3에 도시된 바와 같이, 상기한 제어부(30)는 일예로, 단계 S100과 S101에서 세탁행정 후 탈수작업이 개시되면, 먼저, 단계 S102와 단계 S103에서 배수펌프를 구동하여 세탁조(4)내의 물을 배수함과 함께 구동모터(5)를 구동하여 구동모터(5)의 탈수속도를 가속시켜 탈수한다.To this end, as shown in Figure 3, the control unit 30, for example, when the dehydration operation is started after the washing stroke in steps S100 and S101, first, by driving the drainage pump in step S102 and step S103 washing tank (4) In addition to draining the water in the) and driving the drive motor 5 to accelerate the dewatering speed of the drive motor (5) to dewater.

그리고, 단계 S104에서 수위검출센서(31)를 통해 세탁조 내의 탈수량을 검출 한다. 그런 후 단계 S105에서, 단계 S104에서 검출된 세탁조 내의 탈수량(A)을, 실험에 의해 미리 설정되어 저장된 배수펌프(10)의 펌핑에 의해 배출되는 물량(B)과 비교하여 탈수량이 배수펌프(10)의 펌핑에 의해 배출되는 물량보다 많으면, 단계 S106에서 구동모터(5)의 탈수속도를 감속 제어하게 된다. 이로 인해, 세탁물에서 배출되는 탈수량이 줄어들게 되어, 배수가 원활히 해져 배수에러가 발생할 가능성을 줄일 수 있게 되고, 아울러, 배수펌프(10)에 과부하가 걸리는 것을 해소시킬 수 있어 배수펌프가 손상되는 것을 미연에 방지할 수 있게 된다.Then, in step S104, the dehydration amount in the washing tank is detected through the water level detection sensor 31. Then, in step S105, the dehydration amount (A) in the washing tank detected in step S104 is compared with the water amount (B) discharged by the pumping of the drain pump (10) preset and stored by experiment, and the dehydration amount is the drainage pump. If more than the amount of water discharged by the pumping of (10), the dehydration speed of the drive motor 5 is decelerated control in step S106. As a result, the amount of dewatering discharged from the laundry is reduced, the drainage is smoothed, and the possibility of drainage error is reduced, and the overload of the drainage pump 10 can be eliminated and the drainage pump is damaged. It can be prevented in advance.

이 후 단계 S107에서 수위검출센서(31)를 통해 세탁조 내의 탈수량을 재검출하고, 단계 S108에서 재검출된 탈수량이 배수펌프(10)의 펌핑에 의해 배출되는 물량과 같거나 적으면, 구동모터(5)의 탈수속도를 원래대로 가속시킨다.Thereafter, in step S107, the dehydration amount in the washing tank is redetected through the water level detection sensor 31, and if the dewatering amount detected again in step S108 is equal to or less than the amount of water discharged by the pumping of the drainage pump 10, the driving is performed. The dehydration speed of the motor 5 is accelerated as it is.

상기한 예는 탈수속도를 감속시킨 후 세탁조내의 탈수량을 재검출하고, 재검출된 탈수량이 배수펌프(10)의 펌핑에 의해 배출되는 물량보다 같거나 적으면, 탈수속도를 원래대로 가속시키는 방식이며, 본 발명은 이에 한정되지 않는다.The above example re-detects the dehydration amount in the washing tank after decelerating the dehydration rate, and if the redetected dehydration amount is less than or equal to the amount discharged by the pumping of the drainage pump 10, the dehydration rate is accelerated to its original state. System, and the present invention is not limited thereto.

즉, 도 4에 도시된 바와 같이, 탈수속도를 감속시킨 후 세탁조내의 탈수량을 재검출하여 배수펌프(10)의 펌핑에 의해 배출되는 물량과 비교하는 대신에, 보다 효율적으로 배수가 이루어지도록 단계 S206에서 탈수속도를 감속시킨 후 이 상태를 단계 S207에서 소정시간동안 유지시킨 후 소정시간이 경과한 후 단계 S108에서 곧바로 탈수속도를 원래대로 가속시킬 수 있다. 이때, 두 가지 방식 모두 배수효율측면에서는 세탁조 내의 탈수량과 상기 배수펌프(10)의 펌핑에 의해 배출되는 물량사이의 차이에 상응하는 속도값으로 탈수속도를 감속시키는 것이 바람직하다.That is, as shown in Figure 4, after the dehydration rate is reduced to re-detect the amount of dehydration in the washing tank to compare with the amount of water discharged by the pumping of the drain pump 10, the step to make the drainage more efficiently After the dehydration speed is reduced in S206, this state is maintained for a predetermined time in step S207, and after the predetermined time has elapsed, the dehydration speed can be accelerated to the original state immediately in step S108. At this time, in both methods, in terms of drainage efficiency, it is preferable to reduce the dehydration speed to a speed value corresponding to the difference between the amount of dehydration in the washing tank and the amount of water discharged by the pumping of the drain pump 10.

이상에서 상세히 설명한 바와 같이, 본 발명은 세탁행정시의 탈수, 헹굼행정시의 탈수 또는 탈수행정시의 탈수시, 탈수에 의해 세탁조 내에 배수되지 않고 남아 있는 탈수량이 배수펌프의 펌핑에 의해 배출되는 물량보다 많아지면, 구동모터의 탈수속도를 감속시킨 후 다시 원래대로 가속시킴으로서 탈수량을 배수펌프의 펌핑 능력에 맞게 적절히 조절할 수 있어 세탁기에 배수에러가 발생하거나, 과부하로 인해 배수펌프가 손상되는 것을 미연에 방지할 수 있는 효과가 있다.As described in detail above, in the present invention, the dehydration in the washing stroke, the dehydration in the rinsing stroke, or the dehydration in the dehydration stroke, the dehydration remaining without being drained into the washing tank by dehydration is discharged by pumping the drain pump. If it exceeds the quantity, the dehydration speed of the drive motor can be reduced and then accelerated again so that the dehydration amount can be adjusted appropriately according to the pumping capacity of the drainage pump.
