The conventional drum washing machine discharges the rinsed wash water to the outside when the rinsing stroke is completed, and rinses by supplying fresh water. In this case, there is almost no residual detergent, so the wash water that can be used for rinsing is also discarded, which causes a problem that the wash water is wasted.
또한 종래의 드럼세탁기는 세탁행정이 시작되면 급수부를 통해 세탁수가 유입되고, 드럼 내에 일정한 수위의 세탁수가 채워지면 드럼이 회전되면서 세탁행정을 수행하였다. 그러나 이와 같은 드럼세탁기는 세탁시 터브에 투입된 세제가 일정량이 용해되지 않은 상태로 드럼에 공급된다. 특히, 가루세제의 경우 소량의 가루세제가 세탁물의 올 사이사이에 끼어 거의 용해가 되지 않기 때문에 효과적인 세탁행정이 되지 못하는 문제점이 있었다. 또한 드럼 내에 일정한 수위로 세탁수가 공급되어 세탁행정이 수행됨으로써, 세탁물 중 충분히 세탁수에 적셔지지 못하고 세탁이 완료되는 문제점이 있었다. 따라서 이를 개선할 필요성이 요청된다.In addition, the conventional drum washing machine wash laundry flows through the water supply unit when the washing operation starts, and when the washing water of a certain level is filled in the drum, the drum rotates to perform the washing operation. However, such a drum washing machine is supplied to the drum in a state in which a certain amount of detergent put into the tub is not dissolved. In particular, in the case of powdered detergent, a small amount of the powdered detergent is sandwiched between all the laundry, so that there is a problem that does not become effective washing administration. In addition, the washing water is supplied to the drum at a constant level, so that the washing administration is performed. Thus, there is a problem in that the washing is not sufficiently wet in the washing water and the washing is completed. Therefore, there is a need for improvement.

Flowchart for
이하, 도 3과 도 4를 참조하여 본 발명의 일 실시예에 따른 드럼세탁기의 세탁수 순환 방법을 설명한다.Hereinafter, a washing water circulation method of a drum washing machine according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4.
제어부(31)는 배수펌프(34)와 공급밸브(28)를 포함한 드럼세탁기의 각 구성요소의 동작을 제어한다. 헹굼이 완료되면, 제어부(31)는 배수밸브(25)를 열고 그에 따라 헹굼수가 배수된다(S210). 헹굼수는 배수호스(24)를 따라 배수펌프(34)까지 차게 되고, 탁도감지센서(23)에 의해 헹굼수의 탁도가 측정되고, 측정된 헹굼수의 탁도값(Sd)과 목표 탁도값(St)을 비교한다(S220). 비교 결과 헹굼수의 탁도값(Sd)이 목표 탁도값(St)보다 작거나 같은 경우, 제어부(31)에서는 배수펌프(22)를 동작시키고 공급밸브(28)의 순환호스(27) 측을 개방시킨다(S230). 일 실시예로서, 헹굼수의 탁도값(Sd)이 목표 탁도값(St)보다 작거나 같은 경우 제어부(31)에서는 배수밸브(25)를 닫고 배수펌프(22)까지 배수된 헹굼수만큼 보충하여 헹굼행정을 수행할 수 있다. The control unit 31 controls the operation of each component of the drum washing machine including the drain pump 34 and the supply valve 28. When the rinsing is completed, the control unit 31 opens the drain valve 25 and accordingly drains the rinsing water (S210). The rinsing water is filled up to the drain pump 34 along the drain hose 24, and the turbidity of the rinsing water is measured by the turbidity sensor 23, and the measured turbidity value Sd and the target turbidity value ( St) is compared (S220). As a result of the comparison, when the turbidity value Sd of the rinsing water is less than or equal to the target turbidity value St, the control unit 31 operates the drainage pump 22 and opens the circulation hose 27 side of the supply valve 28. Let (S230). As an exemplary embodiment, when the turbidity value Sd of the rinsing water is less than or equal to the target turbidity value St, the controller 31 closes the drain valve 25 and replenishes the amount of rinsing water drained up to the drain pump 22. Rinsing stroke can be performed.
비교 결과 헹굼수의 탁도값(Sd)이 목표 탁도값(St)보다 큰 경우, 제어부(31)에서는 배수펌프(22)를 동작시키고 공급밸브(28)의 배수구(26) 측의 배수호스(24) 측을 개방시킨다(S240).As a result of the comparison, when the turbidity value Sd of the rinsing water is larger than the target turbidity value St, the control unit 31 operates the drain pump 22 and the drain hose 24 on the drain port 26 side of the supply valve 28. ) To open the side (S240).
이와 같이 드럼세탁기의 세탁수 순환 장치는 드럼세탁기의 배수호스(24)로 배수되는 헹굼수의 탁도값(Sd)을 측정 비교하고 순환호스(27)와 공급밸브(28)를 결합하여 헹굼수를 순환 공급하므로 잔류 세제가 거의 없는 깨끗한 헹굼수를 다시 헹굼행정에 사용할 수 있어 헹굼시 사용되는 물 사용량을 줄일 수 있다.Thus, the washing machine circulation device of the drum washing machine measures and compares the turbidity value (Sd) of the rinsing water drained to the drain hose 24 of the drum washing machine, and combines the circulation hose 27 and the supply valve 28 to rinse the rinsing water. Because of the circulating supply, clean rinsing water with little residual detergent can be used in the rinsing cycle again, thereby reducing the amount of water used for rinsing.
도 5는 본 발명의 다른 실시예에 따른 드럼세탁기의 세탁수 순환 방법을 설명하기 위한 흐름도이다.5 is a flowchart illustrating a washing water circulation method of the drum washing machine according to another embodiment of the present invention.
도 2, 도 3 및 도 5에 도시된 바와 같이, 세탁이 시작되면 제어부(31)에서는 설정된 시간이 경과하였는지 판단한다(S310). 판단 결과 설정된 시간이 경과한 경우 제어부(31)에서는 배수펌프(22)를 동작시키고 공급밸브(28)의 순환호스(27) 측을 개방시켜 세탁수가 순환호스(27)를 따라 드럼(30) 내로 공급되게 한다(S320). 제어부(31)에서는 세탁이 완료되었는지 판단하고(S330), 세탁이 완료된 경우 배수펌프(22)는 그대로 동작시키고 공급밸브(28)의 배수구(26) 측의 배수호스(24) 측을 개방시켜 세탁수가 배수호스(24)를 따라 배수구(26)로 배출되게 한다(S340). 이와 같이 드럼세탁기의 세탁수 순환 장치는 드럼세탁기의 배수펌프(22)의 토출부에 순환호스(27)와 공급밸브(28)를 결합하여 세탁행정 중에 세탁수를 순환 공급하므로 세제가 보다 잘 용해될 수 있고, 세탁물의 올 사이사이에 세제가 끼이는 것을 방지할 수 있다. 따라서 세탁이 종료된 후에 세탁물에 소량의 세제가 잔존하는 것을 방지할 수 있다. 또한 세탁수의 순환 공급에 따라 세제가 잘 용해되어 공급되므로 세탁력이 상승되고 세척시간을 단축시킬 수 있고, 세탁행정에서 사용하는 터브(29) 내의 물을 순환시켜 사용하므로 물 사용량을 줄일 수 있다.As shown in FIGS. 2, 3, and 5, when washing is started, the controller 31 determines whether the set time has elapsed (S310). As a result of the determination, when the set time has elapsed, the control unit 31 operates the drainage pump 22 and opens the circulation hose 27 side of the supply valve 28 to wash the water along the circulation hose 27 into the drum 30. To be supplied (S320). The control unit 31 determines whether the washing is completed (S330), when the washing is completed, the drain pump 22 is operated as it is and the drain hose 24 side of the drain port 26 side of the supply valve 28 is opened to wash The water is discharged to the drain hole 26 along the drain hose 24 (S340). Thus, the washing machine circulation device of the drum washing machine combines the circulation hose 27 and the supply valve 28 to the discharge portion of the drain pump 22 of the drum washing machine to circulate and supply the washing water during the washing process so that the detergent is better dissolved. It is possible to prevent the detergent from being caught between all the laundry. Therefore, a small amount of detergent can be prevented from remaining in the laundry after washing is finished. In addition, since the detergent is well dissolved and supplied according to the circulation supply of the washing water, washing power may be increased and the washing time may be shortened, and water consumption may be reduced because the water used in the tub 29 used in the washing stroke is circulated.
