摘要： Disclosed is a laundry treatment apparatus, which directly heats a drum accommodating laundry and is enhanced in efficiency and safety. The laundry treatment apparatus includes a tub, a drum formed of a metal material and rotatably provided inside the tub to accommodate laundry, an induction module spaced apart from a circumferential surface of the drum to heat the circumferential surface of the drum via a magnetic field that is generated when current is applied to a coil, a lifter provided in the drum to move the laundry inside the drum when the drum rotates, a temperature sensor provided to sense a temperature of the drum, and a module controller configured to control an output of the induction module so as to control an amount of heat generated from the circumferential surface of the drum. The module controller controls the amount of heat based on the temperature sensed by the sensor.
