Abstract

본 발명은 세탁하고자 하는 세탁량 즉 부하를 홀센서를 이용한 회전펄스의 수로 감지할때, 감지하고자 하는 부하를 보다 정확하게 감지할수 있도록 한 세탁기의 부하감지방법에 관한 것으로, 본 발명은 세탁하고자 하는 세탁량에 대한 부하감지시, 급수되는 세탁수가 극소수위에 도달하였을때, 소수위급수 유무를 판단하면서 모터를 비교적 짧은 소성의 시간동안 온하고, 긴시간 오프하고, 상기 소수위 급수완료시 비교적 긴 소정의 시간동안 모터를 온, 오프하면서 정, 역회전하여 소정의 횟수 회전펄스를 감지하면서 부하를 감지하도록 한 것을 특징으로 한다.The present invention relates to a load sensing method for a washing machine which can more accurately detect a load to be sensed when detecting a washing amount to be washed, that is, a load, as a number of rotation pulses using a hall sensor, When the load is detected, the motor is turned on for a relatively short firing time and turned off for a long time while determining the presence of a small number of emergency water, The load is detected while sensing the predetermined number of rotation pulses by forward and reverse rotation while the motor is turned on and off.

Description

세탁기의 부하감지방법How to detect load in washing machine

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 본 발명에 이용되는 세탁기의 개략적인 제어 블럭도.FIG. 1 is a schematic control block diagram of a washing machine used in the present invention. FIG.

제2도는 본 발명 세탁기의 부하감지방법에 대한 플로우챠트.FIG. 2 is a flowchart of a load sensing method of the washing machine of the present invention. FIG.

Claims (2)

세탁하고자 하는 세탁량에 대한 부하감지시, 급수되는 세탁수가 극소수위에 도달하였을때, 소수위급수 유무를 판단하면서 모터를 비교적 짧은 소성의 시간동안 오하고, 긴시간 오프하고, 상기 소수위 급수완료시 비교적 긴 소정의 시간동안 모터를 온, 오프하면서 정, 역회전하여 소정의 횟수 회전펄수를 감지하여 부하량을 산출하도록 한 것을 특징으로 세탁기의 부하감지방법.When the load of laundry to be cleaned is detected, when the number of washing water reaches a very small number, the motor is turned off for a relatively short firing time while judging the presence of a small number of emergency water and turned off for a long time, And detecting a predetermined number of pulses of rotation by forward and reverse rotation while turning on and off the motor for a long predetermined time to calculate a load. 제1항에 있어서, 상기 세탁수의 극소수위 도달시 모터를 0.1초 온, 5초 오프하고, 소수위급수 완료시 모터를 0.4초 온, 0.6초 오프하면서 정, 역회전 하도록 이루어짐을 특징으로 하는 세탁기의 부하감지방법.The washing machine according to claim 1, wherein when the washing water reaches a small number of the washing water, the motor is turned off for 0.1 seconds on and off for 5 seconds, A method of detecting a load of a washing machine. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
