Abstract
본 발명은 포량 감지에 의한 급수 제어 방법에 관한 것으로, 일반적으로 세탁기는 같은 포량일지라도 포 상태에 따라 여력 펄스의 갯수가 다르다. 따라서 종래에는 펄스 갯수만으로 포량을 감지함으로 포량 감지 에러가 발생하여 포량에 따른 적정 급수가 수행되지 않음으로써 세탁 성능저하 및 물 비산이 발생하거나 포가 손상되는 문제점이 있었다.The present invention relates to a water supply control method by detecting a quantity of water, and in general, even if the washing machine has the same amount of water, the number of spare pulses varies depending on the state of the gun. Therefore, in the related art, a quantity of detection error occurs by detecting a quantity of pulse only by the number of pulses, so that proper water supply is not performed according to the quantity of the laundry, resulting in a decrease in washing performance and water scattering or damage to the foam.
이러한 점을 감안하여 본 발명은 세탁조에 포가 투입되면 소정 시간 모터의 온, 오프에 따른 펄스 및 전류를 계수한 후 적산된 펄스의 갯수와 전류 평균값에 따라 포량을 감지하여 수위를 설정하고 물이 공급된 후 2차로 소정 시간 모터의 구동에 따른 펄스 및 전류를 계수하여 설정된 펄스의 갯수와 전류값과 비교함으로써 적정 수위를 판별하게 구성한 것으로, 본 발명은 모터 온, 오프시 전류 평균 값과회전 자계에 따른 펄스의 갯수를조합하여 포량을 감지한 후 2차로 전류 평균값과 펄스를 적산하여 적정수위인지 판별함으로 정확한 포량 감지로 세탁 성능 저하 및 물 비산을 방지하여 효율적인 세탁 행정을 수행할 수 있다.In consideration of this point, the present invention counts pulses and currents according to the on / off of the motor for a predetermined time when the cloth is put into the washing tank, sets the water level by detecting the amount of water according to the number of accumulated pulses and the current average value, and supplies water. After determining the proper level by counting the pulse and the current according to the driving of the motor for a predetermined time and comparing it with the set number of pulses and the current value, the present invention relates to the average current value at the time of motor on and off and the rotating magnetic field. By combining the number of pulses according to the detection of the amount of capacity, the second average current value and pulses are integrated to determine whether the proper level of water by accurate detection of the washing performance to prevent the washing performance degradation and water scattering can be carried out an efficient washing stroke.
