Abstract

A washing machine and a method of controlling the same are disclosed. The amount of laundry that is introduced into the washing machine is measured using gravity and inertia applied during the operation of a motor, whereby it is possible to precisely calculate the amount of laundry and to minimize the effects of the initial position of the laundry and the movement of the laundry. In addition, a current value of the motor that is operated is used to measure the amount of laundry without a sensor. Furthermore, precision in determining the amount of laundry is improved, and the amount of laundry is determined within a short time. Consequently, it is easy to commence the spin-drying operation, thereby reducing washing time and saving energy.
