Abstract
본 발명은 세탁기에 있어서, 마이크로컴퓨터에 의해서 행해지는 인터럽트 시간간격을 단축하여 모터를 보다 정확하게 제어함과 동시에 제어소자를 보호할뿐만 아니라 모터의 위상 제어도 가능토록 하는 세탁기의 모터제어장치 및 제어 방법에 관한것으로써, 마이크로컴퓨터와, 상용교류전원를 입력하여 강압후 전파정류하는 전원부와, 상기 전원부로 부터의 전압을 분배하는 전압분배부과, 상기 분배된 전압에 의해 일정주기의 구형파 신호를 발생하는 인터럽트 신호발생부와, 상기 마이크로컴퓨터의 제어신호에 의해 모터를 구동하는 모터 구동부로 이루어진 세탁기의 모터 제어장치에 있어서 상기 인터럽트 신호발생부는 마이크로컴퓨터의 인터럽트단자 및 입력단자에 구형파 펄스신호를 입력하며, 상기 전원부의 전파정류는 2개와 다이오드를 이용하여 수행토록 하며, 마이크로컴퓨터에 입력되는 구형파 신호를 판별한후 AC 전압의 제로점을 설정하는 제1스텝과, 모터구동명령 신호의 입력여부에 따라 구형파신호의 하이레벨 신호중 일정지점에 도달하였을때 모터구동신호를 출력하는 제2스텝과, 모터구동명령 신호의 오프 여부에 따라 모터의 구동을 제어하는 제3스텝으로 이루어진 것을 특징으로 한다.The present invention provides a washing machine motor control apparatus and control method for shortening interruption time intervals performed by a microcomputer to more precisely control a motor and to protect a control element as well as to control a phase of the motor. In accordance with the present invention, a microcomputer, a power supply unit for step-down and full-wave rectification by inputting a commercial AC power supply, a voltage distribution unit for dividing a voltage from the power supply unit, and an interrupt for generating a square wave signal of a predetermined period by the divided voltages In the motor control apparatus of a washing machine comprising a signal generator and a motor driver for driving a motor by a control signal of the microcomputer, the interrupt signal generator inputs a square wave pulse signal to an interrupt terminal and an input terminal of the microcomputer. Full-wave rectification of power supply part After the square wave signal is input to the microcomputer, the first step of setting the zero point of the AC voltage and the high level signal of the square wave signal are reached according to the input of the motor drive command signal. And a second step of outputting a motor drive signal, and a third step of controlling driving of the motor depending on whether the motor drive command signal is off.
