MAGNETIC VARIABLE DAMPING VIBRATION REDUCING CONTROL METHOD FOR WASHING MACHINE

摘要

A magnetic variable damping vibration reducing control method for a washing machine comprises: disposing a variable damping vibration damper (33) at a bottom portion of an outer drum (22) of the washing machine wherein one end of the variable damping vibration damper (33) is connected to the outer drum (22) and the other end is connected to a housing (44) of the washing machine; during phases of different spinning speeds inputting different electric currents to the variable damping vibration damper (33) and generating by the variable damping vibration damper (33) corresponding damping forces to reduce vibration; and during the vibration reduction detecting a vibration magnitude and an actual rotation speed of a motor in real time calculating a difference between the actual rotation speed and a target rotation speed and adjusting according to the vibration magnitude and the difference between the actual rotation speed and the target rotation speed the magnitude of the inputted electric current in real time.
