Abstract

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.

Description

technical field [0001] Embodiments of the present disclosure relate to a washing machine, and more particularly, to a washing machine including a drum for improving washing efficiency. Background technique [0002] Generally, the washing machine is a pulsator type washing machine or a drum type washing machine depending on a washing method. Each of the pulsator type washing machine and the drum type washing machine includes a tub and a drum. [0003] However, in the case of the pulsator type washing machine, the rotation axis of the drum performing washing may be set vertically to the ground. A pulsator can be installed on the lower part of the drum to generate water flow. In the pulsator type washing machine, when the drum and the pulsator are rotated by a motor in a state where the laundry and detergent water are put in the drum, the pulsator agitates the laundry put in the drum together with the wash water, thereby removing dirt from the laundry. Sewage. [0004] In c...
