본 발명은 세탁기의 탈수모터 정지방법에 관한 것으로, 특히 탈수시 도어가 열렸을 때 단시간에 탈수모터가 정지되도록 한 탈수모터 정지방법에 관한 것이다.The present invention relates to a method for stopping a dehydration motor of a washing machine, and more particularly, to a method for stopping a dehydration motor to stop the dehydration motor in a short time when the door is opened during dehydration.
일반적으로 세탁기의 경우, 탈수시 도어를 열었을 때, 탈수모터에 공급되는 전원을 차단시켜 탈수모터가 정지하도록 함으로써, 탈수조가 정지하도록 되어 있으나, 상기 탈수조는 비록 탈수모터가 정지하였다 하더라도, 관성에 의하여 회전을 하도록 되어 있어 사용자가 부주의에 의하여 탈수조에 손을 넣게 되는 경우 손상을 입게 되는 위험성을 내포하고 있을 뿐만 아니라. 탈수조가 완전 정지할 때까지 기다려야 하기 때문에 세탁시간이 길어지게 되기 때문에 이용에 다소 불편함을 주는 문제점을 가지게 되었다.In general, in the case of a washing machine, when the door is opened during dehydration, the dehydration motor is stopped by shutting off the power supplied to the dehydration motor so that the dehydration motor is stopped. However, even though the dehydration motor is stopped, the dehydration tank is stopped by inertia. Not only does it rotate, it also implies the risk of damage if the user inadvertently puts his hand in the dehydrator. Since the dehydration tank has to wait until it stops completely, the washing time becomes longer, which causes a problem of inconvenience.
따라서 본 발명의 목적은 세탁기에서 탈수시 도어를 열게되면, 모터부의 제어 Control에 의하여 탈수조가 단시간에 정지되도록 함으로써, 탈수조 회전에 의한 손상을 방지하고, 아울러 이용에 편리함을 주고자 하는데 있으며, 상기의 목적을 실현하기 위하여 본 발명은 탈수시 탈수조를 회전시키는 모터 인버터 구동부에 모터 구동 정지를 감지하는 자석을 이용한 홀센서를 부착하여, 도어 열림이 소정시간이 되었을 경우 모터에 흐르는 자계방향을 반대로 하여 단시간에 이용한 홀센서를 부착하여, 도어 열림이 소정시간이 되었을 경우 모터에 흐르는 자계방향을 반대로 하여 단시간에 모터구동을 정지하도록 한 것을 특징으로 한다.Accordingly, an object of the present invention is to prevent the damage caused by the rotation of the dehydration tank by the control control of the motor unit to stop the dehydration tank in a short time when the door is opened during dehydration in the washing machine, and to provide convenience for use. In order to realize the object of the present invention, a hall sensor using a magnet for detecting a motor driving stop is attached to a motor inverter driving unit that rotates a dehydration tank during dehydration, and when the door is opened for a predetermined time, the magnetic field flowing to the motor is reversed. By attaching the hall sensor used in a short time, when the door opening is a predetermined time, the motor driving is stopped in a short time by reversing the magnetic field flowing to the motor.
이하 첨부된 도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Dehydration by flowing clockwise to the upper coil, but when the door switch (SW1) of the door detection unit (4) is turned on during the dehydration operation, that is, the door is opened, the door opening time determination step in the microcomputer (b) Go to 21) and determine whether the time that the door is open is longer than a predetermined time (0.3 seconds), and if the time that the door is opened is not more than the predetermined time, the dehydration operation is continued, and if the door opening time is more than the predetermined time The microcomputer (b) stops driving the motor by cutting off the power supplied to the motor driving part (bar), but the motor rotates with rotational force due to inertia. In ICOM (B), the motor signal inversion step 22 is input, and the driving signal is inputted to the driving signal output terminal counterclockwise for a predetermined time, whereby the magnetic field flowing to the motor of the motor driving part (bar) is reversed. In the microcomputer (b), the motor stop determination step (23) stops the washing tank while determining whether the motor is stopped through the hall sensor (HS) as shown in FIG. will be.
