본 발명은 세탁기에 관한 것으로, 특히 탈수시간 산출방법에 관한 것이다.The present invention relates to a washing machine, and more particularly to a method for calculating the dehydration time.
종래 세탁기의 탈수시간은 중량 센서에 의한 세탁물의 중량과 고,중, 저,소로 구분되는 세탁조 내의 수위에 따라 세탁 초기시에 미리 결정된다. 이에 따라, 세탁물의 종류, 즉, 화학섬유, 면섬유등에 무관하게 탈수시간이 결정되고 이 결정된 탈수시간에 따라 세탁물이 탈수되므로 세탁물의 종류에 따라 탈수시간이 필요이상으로 길어지거나 또는 필요이하로 짧아지게 되는 현상이 종종 발생되었다. 결국, 세탁물이 손상되거나 또는 세탁물의 탈수도가 저하되는 문제점이 있었다.The dehydration time of a conventional washing machine is predetermined at the initial washing time according to the weight of the laundry by the weight sensor and the water level in the washing tank divided into high, medium, low and small. Accordingly, the dehydration time is determined irrespective of the type of laundry, that is, chemical fiber or cotton fiber, and the dehydration time is dehydrated according to the determined dehydration time, so that the dehydration time becomes longer or less than necessary depending on the type of laundry. Often occurs. As a result, there is a problem that the laundry is damaged or the degree of dehydration of the laundry is lowered.
본 발명은 상기 단점을 제거키 위한 것으로, 배수구를 통해 배출되는 세탁수의 청정도(맑은정도)를 이용하여 세탁물에 상응하도록 탈수시간을 적절하게 산출할 수 있는 방법을 제공하는데 그 목적이 있다.The present invention is to eliminate the above disadvantages, an object of the present invention is to provide a method for properly calculating the dehydration time to correspond to the laundry by using the cleanness (clearness) of the wash water discharged through the drain.
위의 목적을 달성하기 위하여, 본 발명에 따르면, 배수구에 배수되는 세탁수의 청정도를 검출하는 검출장치를 구비한 세탁기에 있어서, 탈수가 시작되면, 검출장치에 의해 감지된 세탁수의 청정도가 설정된 값에 도달할 때 까지의 시간을 카운트 한다.In order to achieve the above object, according to the present invention, in the washing machine provided with a detection device for detecting the cleanliness of the wash water drained to the drain, when dehydration is started, the cleanliness of the wash water detected by the detection device is set Count the time until the value is reached.
이어서, 상기 카운트된 시간을 설정된 기준시간과 비교하여, 길수록 앞으로의 탈수시간을 비례적으로 길게 결정하고, 짧을수록 앞으로의 탈수시간을 비례적으로 짧게 결정한다.Subsequently, the counted time is compared with the set reference time, and the longer the dehydration time is determined proportionally longer, the shorter the future dehydration time is determined proportionally shorter.
본 발명은 구현하기 위한 구성 및 원리를 첨부된 제1도 내지 제3도를 참조하여 설명하기로 한다.DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to FIGS.
제1도에 나타낸 바와같이, 배수구 하우징(1)에는 배수되는 세탁수의 청정도를 검출하기 위한 장치로서, 포토커플러(2)가 설치된다.As shown in FIG. 1, a drain coupler 1 is provided with a photocoupler 2 as an apparatus for detecting the cleanliness of wash water to be drained.
제1도에서, 번호 3는 급수밸브를, 번호 4는 내측탱크를, 번호 5는 세탁모터를 나타낸 것이다.In FIG. 1, numeral 3 denotes a water supply valve, numeral 4 denotes an inner tank, numeral 5 denotes a washing motor.
제2도는 포트커플러(2)와 이것에 연결되는 마이크로 컴퓨터(6) 및 모터 구동부(7)와의 연결관계를 나타내는 블록도이다.2 is a block diagram showing the connection relationship between the port coupler 2 and the microcomputer 6 and the motor drive unit 7 connected thereto.
제2도에서, 번호 2a는 배수되는 세탁수의 청정도에 따라 빛을 발하는 포토다이오드이고, 번호 2b는 포토다이드(2a)로 부터 빛을 수광하여 소정전압을 출력하는 포토트랜지스터를 지시하는 것이다.In FIG. 2, reference numeral 2a denotes a photodiode that emits light according to the cleanliness of the wash water drained, and reference numeral 2b denotes a phototransistor that receives light from the photodide 2a and outputs a predetermined voltage.
제3도는 세탁 과정중 배수구를 동해 배출되는 세탁수의 일반적인 청정도를 시간과 전압 그래프로 나타낸 것이다.Figure 3 shows the general cleanliness of the wash water discharged through the drain during the washing process in a time and voltage graph.
즉, 마기막 헹굼과정을 마친후 배수되는 세탁수의 청정도를 제1도 및 제2도의 포토커플러(2)를 통해 얻어진 전압의 크기로서 나타내는 그래프이다.That is, it is a graph showing the cleanliness of the wash water drained after the last rinsing process as the magnitude of the voltage obtained through the photocoupler 2 of FIGS. 1 and 2.
제3도에 나타낸 바와같이, 마지막 헹굼후 배수되는 세탁수는 깨끗하기 때문에 높은 청정도를 갖는다. 이어서, 배수가 끝난후 밸런스 탈수시에는 배수되는 세탁수가 기포성분을 갖고 있기 때문에 빛의 산란현상이 발생한다. 따라서, 이때의 세탁수의 청정도는 가장 낮은 상태가 된다. 이어서, 밸런스 탈수후 탈수가 시작되면 기포가 서서히 제거되고. 어느정도 세탁물에서 세탁수가 탈수되면 배수구를 통해 배출되는 세탁수의 양이 줄어들므로 세탁수의 청정도는 증가하게 된다.As shown in FIG. 3, the wash water drained after the last rinse has a high degree of cleanness because it is clean. Subsequently, when the balance is dewatered after draining, light scattering occurs because the wash water drained has a bubble component. Therefore, the cleanliness of the wash water at this time is the lowest state. Subsequently, when dehydration starts after balance dehydration, air bubbles are gradually removed. If the wash water is dewatered to some extent, the amount of wash water discharged through the drain is reduced, thereby increasing the cleanliness of the wash water.
제3도와 같은 실험을 통해 밸런스 탈수후 탈수과정 중 세탁수의 청정도가 어느정도 증가된 상태를 기준청정도를 설정하고 이 설정된 청정도. 값을 제2도의 마이크로 컴퓨터(6)에 기억시킨다.Through the experiment as shown in FIG. 3, the standard cleanliness is set based on the state in which the cleanliness of the wash water is increased to some extent during the dehydration process after the balance dehydration. The value is stored in the microcomputer 6 of FIG.
본 발명에서는 이 기준청정도 값을 이용하여 전체 탈수시간을 산출하고자 한다.In the present invention, the total dehydration time is to be calculated using the reference cleanliness value.
여기서, 밸런스 탈수란, 탈수시간전에 세탁물의 엉킴을 방지하기 위하여 저속으로 좌.우측으로 교대로 소정횟수 회전시키는 탈수과정을 말한다.Here, the balance dehydration refers to a dehydration process in which a predetermined number of turns are alternately rotated left and right at a low speed in order to prevent tangling of laundry before the dehydration time.
본 발명의 실시예 시스템 프로그램의 과정을 나타내는 플로우챠트인 제4도를 참조하여 설명하면 다음과같다.An embodiment of the present invention will be described with reference to FIG. 4, which is a flowchart showing a process of a program.
먼저, 제2도의 모터구동부(7)를 통해 모터(5)가 구동되어 탈수가 시작되면 배수구에 설치된 포토커플러(2)는 배출되는 세탁수의 청정도를 검출하여 마이크로 컴퓨터(6)에 출력한다.즉, 제3도에 나타낸 바와같이, 밸런스 탈수후 세탁수의 청정도는 서서히 증가하게 된다.First, when the motor 5 is driven through the motor driving unit 7 of FIG. 2 and dewatering starts, the photocoupler 2 installed in the drain port detects the cleanliness of the washing water discharged and outputs it to the microcomputer 6. That is, as shown in FIG. 3, the cleanliness of the wash water gradually increases after the balance dehydration.
검출된 청정도는 전압성분으로서 마이크로 컴퓨터(6)에 입력되고 마이크로 컴퓨터(6)에 내장된 아날로그-디지탈 컨버터에 이해 디지탈 신호로 변환된다. 마이크로 컴퓨터(6)는 탈수모터(5)가 구동되어 탈수가 시작된 직후 부터 l초씩 시간을 증가시켜 배출되는 세탁수의 청정도가 3V가 될때까지의 시간을 카운트한다. 세탁수의 청정도가 3V가 되지 않으면 시간 카운터를 계속하고 3V가 되면 그때까지 카운트된 시간(t)이 설정된 기준시간(T)보다 큰지 또는 작은지릍 체크한다. 더 크면 세탁물이 많거나 또는 세탁수가 많은 것으로 판단하여 카운트된 시간(t)에 비례하여 길게 잔여 탈수시간을 산출하고 더 작으면 세탁물이 적거나 또는 세탁수가 적은 것으로 판단하여 카운트된 시간(t)에 비례하여 잔여 탈수시간을 산출한다.The detected cleanliness is input to the microcomputer 6 as a voltage component and converted into a digital signal for understanding in an analog-digital converter built in the microcomputer 6. The microcomputer 6 counts the time until the cleanliness of the discharged wash water reaches 3V by increasing the time by l seconds from immediately after the dehydration motor 5 is driven to start dehydration. If the cleanliness of the wash water does not reach 3V, the time counter is continued, and if it reaches 3V, it is checked whether the time t counted up to that time is larger or smaller than the set reference time T. If it is larger, it is determined that there is more laundry or more wash water, and the remaining dehydration time is calculated in proportion to the counted time (t). Proportionately calculate the remaining dehydration time.
이후의 과정은 일반적인 세탁과정과 유사하므로 그 설명을 생략한다.Since the following process is similar to the general washing process, the description thereof is omitted.
이상 설명한 바와 같이 본 발명에 따르면, 배수구를 통해 배출되는 세탁수의 청정도를 검출하는 것에 의해 세탁수와 세탁물의 양 및 세탁물의 종류에 따라 다르게 탈수시간을 산출함으로서 적절하게 탈수시간을 결정할 수 있을 뿐아니라 필요이상의 탈수를 방지함으로써 세탁물의 훼손을 방지할 수 있게 된다.As described above, according to the present invention, the dehydration time can be appropriately determined by calculating the dehydration time differently according to the amount of laundry and the amount of laundry and the type of laundry by detecting the cleanliness of the wash water discharged through the drain. In addition, it is possible to prevent damage to the laundry by preventing more dehydration than necessary.
