Laundry treatment machine and method of operating the same

摘要

Disclosed are a laundry treatment machine and a method of operating the same. The method of operating the laundry treatment machine that processes laundry via rotation of a wash tub includes accelerating (S720) a rotation velocity of the tub during an acceleration section, rotating (S730) the tub at a constant velocity during a constant velocity section, and sensing (S740) an amount of laundry in the tub based on output current flowing through a motor that is used to rotate the tub during the acceleration section and output current flowing through the motor during the constant velocity section. This ensures efficient sensing of amount of laundry.
