이하, 상기와 같은 본 발명의 기술적 사상에 따른 실시예를 첨부한 도면을 참조하여 구체적으로 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, embodiments according to the spirit of the present invention as described above will be described in detail.

도 2는 본 발명의 실시예에 따른 세탁기의 배수 제어 방법을 설명하기 위한 흐름도이다.2 is a flowchart illustrating a method for controlling drainage of a washing machine according to an embodiment of the present invention.

여기에 도시한 바와 같이, 먼저 본 발명의 실시예에 따른 세탁기는 세탁, 배수, 탈수 행정이 미리 설정된 프로그램에 따라 순차적으로 수행되므로, 세탁 행정 후 배수밸브를 개방하여 배수 행정을 수행한다(S10).As shown here, first, the washing machine according to an embodiment of the present invention is sequentially performed according to a washing, draining, and dehydrating stroke according to a predetermined program. .

이후, 상기 배수 행정이 완료되면(S11) 세탁조 내에 오염된 잔수가 잔류하게 되는데 상기 오염된 잔수를 제거하기 위한 첫 번째 단계로 배수밸브를 폐쇄한 다음 급수밸브를 개방하여 급수를 행한다(S12). Thereafter, when the draining stroke is completed (S11), the contaminated water remains in the washing tank. As a first step to remove the contaminated water, the water is closed by closing the drain valve and then opening the water supply valve (S12).

이때, 수위센서를 통해 급수된 물의 수위를 측정하고(S13) 측정된 수위값을 설정수위값과 비교하여 상기 측정수위값이 설정수위값에 도달했는지를 판단한다(S14). 참고로, 상기 설정수위값은 상기 오염된 잔수를 완전히 배수하기에 적정한 수위값으로 설정되는 것이 바람직하다.At this time, the water level of the water supplied through the water level sensor is measured (S13) and the measured water level value is compared with the set water level value to determine whether the measured water level value reaches the set water level value (S14). For reference, the set water level value is preferably set to an appropriate water level value to completely drain the contaminated residual water.

판단 결과, 상기 측정수위값이 설정수위값에 도달하지 않은 것으로 판단되면(S14) 급수밸브를 그대로 개방한 채 급수를 행한 후(S12) 급수된 물의 수위를 측정하고(S13) 측정된 수위값을 설정수위값과 비교하여 상기 측정수위값이 설정수위 값에 도달했는지를 다시 판단하게 된다(S14).As a result of determination, when it is determined that the measured water level value does not reach the set water level value (S14), the water supply is performed with the water supply valve open as it is (S12), and then the water level of the water supply is measured (S13) and the measured water level value is determined. It is again determined whether the measured level value reaches the set level value by comparing with the set level value (S14).

하지만, 판단 결과, 상기 측정수위값이 설정수위값에 도달한 것으로 판단되면(S14) 급수밸브를 폐쇄한 후 펄세이터를 회전 구동시킨다(S15). 여기서, 펄세이터를 채용한 일반 세탁기의 경우에는 상기와 같이 펄세이터를 회전 구동시키지만, 드럼을 채용한 드럼 세탁기의 경우에는 드럼을 회전 구동시키도록 구현되는 것이 바람직하다.However, when it is determined that the measured water level value reaches the set water level value (S14), the water supply valve is closed and the pulsator is driven to rotate (S15). Here, in the case of a general washing machine employing a pulsator, the pulsator is rotationally driven as described above, but in the case of a drum washing machine employing a drum, the drum is rotationally driven.

마지막으로, 상기 펄세이터 또는 드럼의 구동을 정지하고 배수밸브를 개방하여 배수를 행하면 본 발명의 실시예에 따른 세탁기의 배수 제어 방법은 종료되게 된다(S16).Finally, when the pulsator or the drum stops driving and drains by opening the drain valve, the drain control method of the washing machine according to the embodiment of the present invention is terminated (S16).

이와 같이, 본 발명의 실시예에 따른 세탁기의 배수 제어 방법은 배수 행정 시 배수 완료 후 소정 수위까지 급수를 행한 다음 펄세이터 또는 드럼을 구동한 후 다시 배수를 함으로써 세탁조에 잔류하는 오염된 잔수를 제거하여 준다. 따라서 헹굼 행정 시 오염된 잔수에 의해 세탁물이 오염되는 것을 막아 세탁력을 향상시킬 수 있다.As described above, the drainage control method of the washing machine according to the embodiment of the present invention removes contaminated residual water remaining in the washing tank by draining water after supplying water to a predetermined level after completion of drainage at the time of drainage and then driving the pulsator or drum. Give it. Therefore, it is possible to prevent the laundry from being contaminated by the contaminated residual water during the rinsing stroke to improve the washing power.

이상에서 본 발명의 바람직한 실시예를 설명하였으나, 본 발명은 다양한 변화와 변경 및 균등물을 사용할 수 있다. 본 발명은 상기 실시예를 적절히 변형하여 동일하게 응용할 수 있음이 명확하다. 따라서 상기 기재 내용은 하기 특허청구범위의 한계에 의해 정해지는 본 발명의 범위를 한정하는 것이 아니다. Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

이상에서 살펴본 바와 같이, 본 발명에 의한 세탁기의 배수 제어 방법은 배수 행정 시 세탁조에 잔류하는 오염된 잔수를 제거하여 줌으로써 헹굼 행정 시 오염된 잔수에 의해 세탁물이 오염되는 것을 막아 세탁력을 향상시켜준다.As described above, the drainage control method of the washing machine according to the present invention improves washing power by preventing contaminated laundry from being contaminated during the rinsing stroke by removing contaminated residue remaining in the washing tank during the draining stroke.
