KR970043487A - Quantity detection device and quantity detection method of washing machine - Google Patents

Abstract

The present invention relates to a quantity detecting device and a quantity detecting method for detecting an amount of washing (amount of laundry) of a washing machine and setting the appropriate level according to the detected result and informing the user of an appropriate amount of detergent input, and particularly provided inside a washing machine lid. Repeatedly measure the time it takes for the reflected ultrasonic wave to come back by using the ultrasonic sensor.The volume of the laundry is measured by the sum of the times, and the agitator of the washing tank is repeatedly run / stopped without supplying water. While measuring the weight of the laundry by the total time it takes to input the pulses according to the remaining rotations generated from the drive motor, the volume is detected by combining the volume measurement data and the weight measurement data, and the appropriate level and detergent Washing capacity detection room that sets the dosage and displays the detergent dosage It's about the law.
