Drum type washing machine

摘要

A washing machine includes a housing which forms an exterior of the washing machine and a tub (20) mounted inside of the housing, the tub (20) having an opening through which laundry may be inserted and removed. A drum (30) is rotatably mounted inside of the tub, the drum (30) having an opening substantially aligned with the opening of the tub, through which laundry may be inserted and removed. A foreign matter shield (200) is configured to prevent foreign matter from entering a space between the tub and the drum by maintaining a gap between the opening of the drum and the tub at a predetermined size during movement of the drum relative to the tub from an initial position to a lower position.
