Washing machine combined with dryer

A washing machine combined with a dryer, comprising:

• a tub;
• a lint collector connected to the tub, the lint collector including a separation hopper in which a moist air introduced from the tub is rotated by a cyclone effect, a lint chamber connected to a bottom of the separation hopper, and a floater installed in the lint chamber to selectively open and close the connection between the separation hopper and the lint chamber;
• an air-vent pipe connected to the lint collector to discharge the moist air from the lint collector;
• a water drain line having one end connected to the tub and the other end connected to the lint collector;
• and
• a blowing unit to blow a heated air into the tub.

A washing machine combined with a dryer, comprising:

• a tub;
• a cyclone lint collector receiving a moist air from the tub;
• and
• a water drain line connected to the cyclone lint collector, wherein the moist air whirls in the cyclone lint collector to separate lint therefrom, the separated lint being discharged through the water drain line together with water passing therethrough.
