Abstract (en)

A washing machine includes a tub (20), a drum (30) rotatably installed at an inside of the tub (20), a drying unit (80) including a blowing fan (84b) suctioning air inside of the tub 820) and the drum (30), and a drying heater (82) heating the air inside of the tub and the drum, a lint filter (85b) filtering foreign substances contained in the suctioned air, and a control unit turning on/off the drying heater (82) and the blowing fan (84b) according to a temperature of a drying duct. If the drying heater (82) is turned off, the control unit determines whether the lint filter (85b) is blocked based on the temperature of the drying duct, the temperature of the tub (20) and the turning-on time of the drying heater (82), and washes the lint filter by determining whether the lint filter (85b) is blocked. The washing of the lint filter (85b) during the drying cycle allows the lint filter to be washed without performing a washing cycle, a rinsing cycle, or a spin cycle, and the air to be circulated between a drying duct and a tub.
