Abstract (en)
A washing machine including a drum capable of improving washing efficiency is provided. The washing machine includes a body (10), a tub (20) provided at an inside the body to store wash water, a drum (30) rotatably provided at an inner side of the tub to accommodate laundry, a driving apparatus (14) to rotate the drum, protrusions (34) that are formed of polygons having polygonal shapes and protruding inward from the drum, and a through-hole (36) provided between adjacent protrusions (34) to drain water. A protrusion having polygons generates frictional force between laundry and the drum, thereby increasing the washing power. The through-holes (36) are uniformly located around the protrusion (34), thereby preventing a spin dry water bottleneck phenomenon that occurs when water from a spin dry is concentrated on a certain through-hole, and thus enhancing the spin dry efficiency.
