세탁기의 제어 방법{METHOD OF CONTROLLING A WASHING MACHINE} Control method of washing machine {METHOD OF CONTROLLING A WASHING MACHINE}

도 1은 본 발명의 실시예에 따른 세탁기를 나타낸 단면도. 1 is a cross-sectional view showing a washing machine according to an embodiment of the present invention.

도 2는 본 발명의 실시예에 따른 세탁기의 제어 방법을 나타낸 순서도. 2 is a flowchart illustrating a control method of a washing machine according to an embodiment of the present invention.

본 발명은 세탁기에 관한 것으로, 특히 세탁 행정에서 세탁수의 오염 상태를 고려한 세탁기의 제어 방법에 관한 것이다. The present invention relates to a washing machine, and more particularly, to a control method of a washing machine in consideration of the dirty state of the washing water in the washing stroke.

일반적으로 전자동 세탁기는 급수, 세탁, 헹굼, 배수 및 탈수 행정을 미리 설정된 프로그램에 의해 순차적으로 수행되어 세탁물을 세탁하도록 이루어진다. In general, the automatic washing machine is performed to sequentially perform a water supply, washing, rinsing, draining, and dewatering strokes by a preset program to wash laundry.

세탁을 실시하면 세탁물에 잔존하는 오염 물질이 세탁물로부터 분리되는데, 이 세탁물로부터 분리된 오염 물질은 세탁수를 오염시킨다. 오염된 세탁수는 세탁 과정의 배수 기능에 의해 세탁조로부터 외부로 배출되고, 세탁조에는 새로운 깨끗한 세탁수가 공급된다. 세탁조에 깨끗한 세탁수가 공급되면 헹굼 기능에 의해 세탁물을 헹구게 된다. 헹굼 기능은 세탁 기능에서 미리 설정된 횟수만큼만 일률적으로 실행을 하게 된다. 만약, 세탁 과정의 헹굼 기능이 3회로 설정되어 있으면 세탁수의 탁도에는 관계없이 3회를 실행한 후 자동으로 탈수 기능을 실행하여 세탁물에 잔존하는 세탁수를 제거하게 된다. When washing is carried out, contaminants remaining in the laundry are separated from the laundry, which contaminates the wash water. The contaminated washing water is discharged from the washing tank to the outside by the drainage function of the washing process, and the fresh washing water is supplied to the washing tank. When clean washing water is supplied to the washing tank, the washing function is used to rinse the laundry. The rinsing function is performed uniformly only a predetermined number of times in the washing function. If the rinsing function of the washing process is set to three times, regardless of the turbidity of the washing water, the washing process is automatically performed after three times to remove the washing water remaining in the laundry.

따라서 미리 설정된 횟수의 헹굼 기능을 실시한 후 지나치게 오염된 세탁수에 의한 세탁물의 재오염 상태와는 상관없이 다음 행정을 실시하게 되므로 탈수 완료 후 세탁물에 다량의 오염 물질이 잔존하는 문제가 있다. Therefore, after the rinsing function is performed a predetermined number of times, regardless of the recontamination state of the laundry due to excessively contaminated washing water, the next administration is performed, and thus, a large amount of contaminants remain in the laundry after dehydration is completed.

본 발명에 따른 세탁기의 제어 방법은 세탁수의 오염도에 따라 세탁물의 재오염 방지 행정을 실시하여 세탁물에 오염 물질이 잔존하지 않도록 하는데 그 목적이 있다. The control method of the washing machine according to the present invention has an object to prevent contaminants from remaining in the laundry by performing a recontamination prevention of the laundry according to the degree of contamination of the wash water.

이와 같은 목적의 본 발명에 따른 세탁기의 제어 방법은, 세탁물이 투입된 세탁기의 세탁조에 세탁수를 급수하여 세탁물을 일정 시간 동안 세탁하고; 세탁이 진행되는 동안 세탁수의 오염도가 '낮음'과 '중간', '높음' 가운데 어느 정도에 해당되는지를 검출하며; 세탁수의 오염도가 '높음'에 해당되는 경우 오염된 세탁수에 의한 세탁물의 재 오염을 막기 위해 세탁 행정을 조기 종료하되, 세탁 행정의 조기 종료에 대한 보상을 위해 가중치를 부여하여 헹굼 행정을 실시한다.The control method of the washing machine according to the present invention for this purpose, by washing the laundry for a predetermined time by supplying the washing water to the washing tank of the washing machine into which the laundry is put; Detect the degree of contamination of the wash water during the washing process is 'low', 'medium', 'high'; If the pollution level of the wash water is 'high', the washing cycle is terminated early to prevent recontamination of the laundry by the contaminated washing water, but the rinsing stroke is performed by giving a weight to compensate for the early termination of the washing stroke. do.

이와 같은 본 발명의 바람직한 실시예를 도 1과 도 2를 참조하여 설명하면 다음과 같다. 도 1은 본 발명의 실시예에 따른 세탁기를 나타낸 단면도이다. 도 1에 나타낸 바와 같이, 세탁수의 담수를 위해 본체케이스(102)의 내부에 수조(104)가 설치되고, 이 수조(104)의 내부에 회전 가능하도록 세탁조(106)가 설치된다. 또 세탁조(106)의 내부에는 세탁수류를 형성하도록 정회전 및 역회전하는 펄세이터(108)가 설치되고, 수조(104)의 하부에는 세탁조(106)와 펄세이터(108)를 회전시키기 위 한 구동장치(110)가 설치된다. 이 구동장치(110)는 구동모터(112)와 동력전달장치(114)로 구성된다. 구동모터(112)는 전원을 인가받아 회전하며, 동력전달장치(114)는 이 회전력이 펄세이터(108)와 세탁조(106)에 선택적으로 전달될 수 있도록 한다. 구동모터(112)와 동력전달장치(114) 사이에는 동력전달을 매개하는 벨트(116)가 연결된다. Referring to Figures 1 and 2 as a preferred embodiment of the present invention as follows. 1 is a cross-sectional view showing a washing machine according to an embodiment of the present invention. As shown in FIG. 1, a water tank 104 is installed inside the main body case 102 for fresh water of the wash water, and a washing tank 106 is installed inside the water tank 104 so as to be rotatable. In addition, a pulsator 108 for forward and reverse rotation is installed in the washing tank 106 to form a washing stream, and a lower portion of the water tank 104 for rotating the washing tank 106 and the pulsator 108. The driving device 110 is installed. The drive device 110 is composed of a drive motor 112 and a power transmission device (114). The drive motor 112 is rotated by receiving power, and the power transmission device 114 allows this rotational force to be selectively transmitted to the pulsator 108 and the washing tank 106. A belt 116 for transmitting power is connected between the drive motor 112 and the power transmission device 114.

도 1에서, 오염도 센서(150)는 세탁수의 오염도를 검출하기 위한 것으로서, 세탁수의 탁도를 통해 그 오염도를 가늠한다. 제어부(152)는 이 오염도 센서(150)를 통해 검출되는 세탁수의 탁도를 통해 세탁수의 오염도를 'L이하'와 'L(낮음)', 'M(중간)', 'H 이상(높음)'의 네 가지로 구분하여, 각 오염도에 대응하는 세탁 및 헹굼, 탈수 행정을 실시한다. In FIG. 1, the pollution degree sensor 150 is for detecting the pollution degree of the wash water, and measures the pollution degree through the turbidity of the wash water. The controller 152 controls the degree of contamination of the wash water through the turbidity of the wash water detected by the pollution degree sensor 150, 'L or less',' L (low) ',' M (middle) ', and' H or more (high). Washing, rinsing, and dehydration strokes corresponding to each pollution degree are carried out.

이와 같은 제어부(152)의 동작을 도 2를 참조하여 설명하면 다음과 같다. 도 2는 본 발명의 실시예에 따른 세탁기의 제어 방법을 나타낸 순서도이다. 도 2에 나타낸 바와 같이, 세탁 행정이 시작되면 세탁수를 급수한다(202). 세탁수의 급수가 완료되면 세탁을 시작한 다음(204) 세탁이 진행되는 동안 세탁수의 오염도를 검출한다(206). 이 때 제어부(152)는 세탁수의 오염도에 대응하는 세탁 및 헹굼, 탈수 행정을 실시하도록 제어한다. The operation of the controller 152 will now be described with reference to FIG. 2. 2 is a flowchart illustrating a control method of a washing machine according to an embodiment of the present invention. As shown in FIG. 2, when the washing stroke starts, the washing water is supplied (202). When the water supply of the washing water is completed, washing is started (204), and the degree of contamination of the washing water is detected (206) while the washing is in progress. At this time, the control unit 152 controls to perform washing, rinsing, and dehydration strokes corresponding to the degree of contamination of the wash water.

먼저 세탁수의 오염도가 'L 미만'인 경우에는 미리 정해진 일반적인 표준 세탁 행정을 실시한다(208). 오염도가 'L미만'인 경우는 세탁수의 희석 없이 그대로 세탁 행정을 실시해도 세탁물이 재오염을 염려하지 않아도 좋은 경우이다. 이 때 표준 세탁 행정이란 오염도와 무관하게 미리 정해진 세탁 모드의 세탁 행정을 실시하 는 것을 의미한다. First, when the degree of contamination of the wash water is less than L, a predetermined general standard washing stroke is performed (208). If the contamination is less than L, the laundry does not have to worry about re-contamination even if the washing process is performed without diluting the washing water. In this case, the standard washing stroke means that the washing stroke of a predetermined washing mode is performed regardless of contamination.

세탁수의 오염도가 'L(낮음)'인 경우에는 세탁수를 추가로 급수하여 오염된 세탁수를 어느 정도 낮춘 다음 잔여 세탁 행정을 실시한다(210). 오염도가 'L(낮음)'인 경우는 오염도가 그리 높지 않지만 세탁물의 재오염을 약간 고려해야 하는 경우로서 약간의 추가 급수를 통해 세탁수의 오염도를 충분히 낮출 수 있는 경우이다. If the degree of contamination of the wash water is 'L' (low), additionally supply the wash water to lower the contaminated wash water to some extent and then perform the remaining washing stroke (210). If the contamination level is 'L', the contamination level is not very high, but the recontamination of the laundry needs to be considered a little, and the additional water can be used to reduce the contamination of the washing water sufficiently.

세탁수의 오염도가 'M(중간)'인 경우에는 현재의 세탁수를 일정량 배수하고, 배수한 양만큼 추가 급수한 다음 잔여 세탁 행정을 실시한다(212). 오염도가 'M(중간)'인 경우는 단순한 추가 급수 만으로는 세탁수의 오염도를 낮추기 힘든 상태로서, 이 경우에는 오염된 세탁수를 어느 정도 버리고 깨끗한 세탁수를 보충함으로써 오염도가 비교적 높은 세탁수의 오염도를 확실히 낮출 수 있도록 한다. If the contamination level of the washing water is 'M', the current washing water is drained by a certain amount, additionally drained by the drained amount, and then the remaining washing process is performed (212). If the pollution level is 'M', it is difficult to reduce the contamination level of the wash water by simple additional water supply.In this case, the pollutant level of the wash water, which has a relatively high pollution rate, is discarded by replenishing the clean laundry water to some extent. Make sure you lower it.

세탁수의 오염도가 'H 이상(높음)'인 경우에는 세탁수의 추가 급수나 보충 만으로는 세탁수의 오염도를 낮추기 어려운 경우로서, 이 때에는 오염된 세탁수에 의한 세탁물의 재오염을 막기 위해 세탁 행정을 현재 시점에서 종료한다(214). If the degree of contamination of the wash water is higher than H (high), it is difficult to reduce the contamination of the wash water by additional water supply or replenishment of the wash water. 214 ends at the current time.

이와 같이, 세탁수의 오염도에 대응하는 각각의 세탁 행정이 완료되면 다음 행정을 실시하게 되는데, 세탁수의 오염도가 각각 'L이하'와 'L(낮음)', 'M(중간)'인 경우에는 일반적인 표준 배수 및 탈수 행정과 헹굼 및 탈수 행정을 실시한다(216~218). As such, when each washing stroke corresponding to the degree of contamination of the wash water is completed, the next stroke is performed. When the degree of contamination of the washing water is 'L', 'L' (low), 'M' (medium), respectively. Standard drainage and dewatering strokes, as well as rinsing and dewatering strokes, are carried out (216-218).

다만, 세탁수의 오염도가 'H 이상(높음)'인 경우에는 미리 설정된 시간보다 조기에 세탁 행정이 종료될 수 있으므로, 일단 세탁 행정을 종료하고 표준의 배수 및 탈수 행정을 실시한 다음(220), 세탁 행정의 조기 종료에 대한 보상을 위해 가중치 를 부여한 헹굼 및 탈수 행정을 실시한다(222). 이 보상 운전은 세탁조의 회전 속도를 높이거나 그 운전 시간을 늘려서 세탁 행정의 조기 종료에 의해 미처 이루어지지 못한 세탁이 헹굼 행정에서 어느 정도 보상될 수 있도록 하기 위한 것이다. However, when the degree of contamination of the wash water is 'H or higher (high)', since the washing stroke may be terminated earlier than the preset time, the washing stroke is ended and the standard drainage and dehydration stroke is performed (220). A weighted rinsing and dehydrating stroke is performed to compensate for the early termination of the washing stroke (222). This compensation operation is intended to increase the rotational speed of the washing tub or increase its operating time so that washing that has not been achieved by the early termination of the washing stroke can be compensated to some extent in the rinsing stroke.

본 발명에 따른 세탁기의 제어 방법은 세탁수의 오염도에 따라 세탁물의 재오염 방지 행정을 실시하여 세탁물에 오염 물질이 잔존하지 않도록 한다. The control method of the washing machine according to the present invention performs a recontamination prevention of the laundry according to the degree of contamination of the wash water so that no contaminants remain in the laundry.
