Abstract

본 발명은 세탁기의 세탁방법에 관한 것으로, 특히 광센서를 이용하여 세탁과 헹굼중에 발생하는 거품 변화량을 감지하여 헹굼수위 및 헹굼 횟수 결정에 반영하므로써, 헹굼성능을 높이고 거품에 대한 소비자의 불만을 해결하기 위한 헹굼횟수 결정방법을 제공하기 위한 것이다.The present invention relates to a washing method of a washing machine, and in particular, by detecting the amount of change of foam generated during washing and rinsing using an optical sensor and reflecting it in the rinsing water level and the number of rinsing, thereby improving rinsing performance and solving consumer complaints about foam. It is to provide a method of determining the number of rinsing to.

이와같은 본 발명의 목적을 달성하기 위한 방법은 세탁조 내부에 설치하여 세탁과 헹굼에서 발생하는 거품의 발생정도를 감지하는 감지수단과, 상기 감지수단으로부터 입력된 탁도전압으로부터 헹굼횟수를 결정하는 제어수단으로 구성한 세탁기를 구비하여, 세탁시 거품의 정도를 광센서의 탁도감지전압으로 20초마다 3분동안 검출하여 그 검출된 값과 평균 탁도 전압으로부터 임의 시간간격에서의 탁도에 따른 평균전압값을 계산하고, 그 계산된 값으로부터 거품발생정도를 판정하는 단계와, 상기 단계에서 판정한 거품값을 기준으로 헹굼을 시작하여 60초가 넘을 때까지 20초 경과 때마다 탁도에 따라 읽어들인 전압값과 앞 단계의 탁도 전압값과의 차의 절대값들을 합산하는 단계와, 상기 단계까지의 경과시간이 60초 이상이 되면, 측정한 전압값을 계산하여 구한 임의 시간 간격에서의 탁도에 따른 평균전압값과 초기 시간간격에서의 평균전압값 및 전·후 단계에서의 전압차의 절대값으로부터 구한 값으로 거품량을 판정하여 거품제거울을 구하는 단계와, 상기 단계에서 구한 거품량과 거품제거율로부터 거품제거도를 판단하여 헹굼횟수를 결정하는 단계로 이루어짐으로써 달성되는 것이다.Such a method for achieving the object of the present invention is installed in the washing tank sensing means for detecting the generation of bubbles generated in the washing and rinsing, and control means for determining the number of rinsing times from the turbidity voltage input from the sensing means The washing machine was configured to detect the degree of foam during washing for 3 minutes every 20 seconds by the turbidity detection voltage of the optical sensor and calculates the average voltage value according to the turbidity at any time interval from the detected value and the average turbidity voltage. Determining the degree of foaming from the calculated value, and starting the rinsing on the basis of the value of the foam determined in the above step, the voltage value and the previous step read according to the turbidity every 20 seconds until 60 seconds is exceeded. Summing the absolute values of the difference from the turbidity voltage value of and if the elapsed time up to the step is 60 seconds or more, the measured voltage value is Determination of the bubble amount by determining the bubble amount from the average voltage value according to the turbidity in the calculated time interval, the average voltage value at the initial time interval, and the absolute value of the voltage difference in the before and after steps. And, it is achieved by the step of determining the number of rinsing by determining the degree of foam removal from the amount of foam and the foam removal rate obtained in the step.
