Claims (5)

A microcomputer, a quantity detecting unit for inputting a detection signal to the microcomputer to detect an amount of laundry and an appropriate level and detergent amount, a water supply valve driving unit for supplying water to the water level determined by the control of the microcomputer; A water level detecting unit for detecting whether water is properly supplied by the operation of the water supply valve driving unit, a detergent motor driving unit for supplying an appropriate amount of detergent to the water level when the water supply is completed up to the determined level, and driving the washing motor Washing motor drive unit and the control of the washing machine using a fuzzy inference, characterized in that the sensor to input the detection signal to the microcomputer to perform the fuzzy inference by detecting the degree of contamination (turbidity) of the laundry during the washing operation Device. The apparatus of claim 1, wherein the optical sensor controller detects turbidity of water for a predetermined time using an optical sensor. The apparatus of claim 2, wherein the light sensor is attached to the light emitting part and the light receiving part symmetrically at a predetermined upper end of the drain valve. A first step of washing by inputting a water supply amount and a detergent amount selected according to the amount of laundry, a second step of detecting turbidity of water generated according to the washing stroke of the first step, and a turbidity of the second step And a third step of performing a fuzzy inference so that washing is performed under an optimal washing condition based on the detection result. 5. The control method according to claim 4, wherein the third step is defined as a membership function by rolling the means for reaching an optimum degree of cleaning into a factor of time. ※ Note: The disclosure is based on the initial application.
