Abstract

본 발명은 브러쉬레스 직류(BLDC)모터 적용 세탁기의 포량 가지 방법 및 그 장치에 관한 것으로, 특히 초기 급수되기 전에 건조상태의 포량을 F,G 시그널과 모터에 흐르는 전류를 조합하여 감지하므로써 최적의 세탁 효과를 기대할 수 있게 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for a quantity of a brushless direct current (BLDC) motor-applied washing machine, and in particular, by detecting a dry quantity of dry condition before initial water supply by combining F and G signals with a current flowing through a motor. The effect is expected.

종래의 기술은 사용자가 포량에 맞는 세제량을 넣기 위해서는 포량감지 수위까지의 급수 시간과 모터 온/오프반복시간(약9초)을 기다려야 하므로 보통 사용자는 세탁량을 어림잡아 넣은 뒤 일시 정지키를 온하여 세탁을 실시하기 때문에 세제량 과다 혹은 부족으로 최적의 세탁효과를 얻을 수 없으며, 또한 유도모터 오프시 역기전력을 펄스 번환함에 있어 비교전압보다 낮은 역기전력을 무시하므로써 정확한 포량감지가 될 수 없는 문제점들이 있었다.The conventional technology requires the user to wait for the water supply time until the quantity detection level and the motor on / off repetition time (about 9 seconds) in order to put the detergent amount suitable for the quantity, so that the user usually turns on the pause key after estimating the amount of washing. Since washing is performed, the optimum washing effect cannot be obtained due to excessive or insufficient detergent amount, and there is a problem in that it is impossible to accurately detect the amount of gas by ignoring the back electromotive force lower than the comparison voltage in pulse switching the back electromotive force when the induction motor is turned off.

본 발명은 이제 모터구동시 모터에 흐르는 전류와 모터오프시 여력회전에 의한 펄스 갯수를 조합하여 건조 상태에서의 포량을 감지할수 있게 하는것임.The present invention is to combine the current flowing through the motor when the motor is driven and the number of pulses caused by the rotation of the power when the motor is off to detect the amount of dry water.
