ABSTRACT:
A drum type washing machine includes a water tub adapted to contain wash water therein, and the water tub has first and second vent holes to circulate air to and from the water tub. The first vent hole is positioned higher than the second vent hole. Thereby, outside air is introduced into the water tub via the second vent hole, and interior air of the water tub is discharged to the outside of the water tub via the first vent hole, thereby allowing the relative humidity inside the water tub to be effectively lowered by virtue of air circulation.
