ABSTRACT:
The present invention discloses a laundry amount sensing apparatus and method for a washing machine. The laundry amount sensing apparatus for the washing machine in which a tub is inclined at a predetermined angle in a non-load state includes a control unit that senses an inclination of the tub, determines a laundry amount corresponding to the sensed inclination of the tub, and controls a spin-drying speed according to the selected laundry amount.
