Washing machine

Abstract

Disclosed herein is a washing machine which has a detergent supply part formed in a door. The detergent supply part is formed in the door and has a function of containing detergent and supplying detergent into a tub through the door. The washing machine has an advantage of considerable space saving compared with the washing machine having the detergent supply part formed in an inner space thereof, thereby minimizing the volume and the number of components of the washing machine.
