VIBRATION QUANTITY DIMINUTIVE CONTROL METHOD FOR WASHING MACHINE

摘要

The present invention relates to a control method for reducing the amount of vibration during dehydration of a washing machine to solve the problem that the dehydration vibration amount is increased due to the detection error that can occur during the first detection by increasing the ALPM when detecting the unbalance amount. .;To this end, the present invention is a washing machine having a power supply, a speed sensor circuit, a microcomputer, a motor driving unit, a variable speed motor unit, etc., to drive a tub in the dewatering direction (CCW) for inflated, tub (Tub) The first step of accelerating to the first unbalance detection speed in the dehydration direction (CW) after the drive stop, and the first step of measuring the first RPM vibration (Max rpm-Min rpm) while maintaining the constant torque (Torque) A second step, a third step of deciding whether or not to enter dehydration with the measured first AlPM vibration amount, a fourth step of accelerating to a second unbalance detection speed when the dewatering entry is determined, and maintaining the constant torque It is achieved by performing a fifth step of measuring the second RPM vibration (Max rpm-Min rpm), and a sixth step of determining whether or not the final dehydration ingress by the measured second RPM vibration amount.
