Abstract
A clothing treatment apparatus includes a tub for providing a space in which washing water is accommodated; a drum rotatably provided inside the tub; a motor for rotating the drum; and an induction heater which is arranged on the outer surface of the tub and which heats the drum. The motor can rotate the drum at a first rotational speed at which laundry accommodated inside the drum is rotated while adhered to the inner circumferential surface of the drum, during heating of the drum by the induction heater.
Claims14
A clothing treatment apparatus comprising:
- a tub having a space for accommodating washing water;
- a drum rotatably located inside the tub, the drum being configured to accommodate laundry therein;
- a motor configured to rotate the drum;
- an induction heater located at an outer surface of the tub, the induction heater being configured to heat the drum;
- a water supply valve configured to control a water supply line connecting an external water source to the tub;
- a laundry weight sensor configured to sense an amount of the laundry accommodated in the drum;
- and
- a controller configured to:
- control the induction heater to heat the drum while controlling the motor to rotate the drum at a first rotational speed at which the laundry accommodated in the drum is rotated to adhere to an inner circumferential surface of the drum;
- and
- control the water supply valve to supply water in an amount corresponding to twice a weight of the laundry accommodated in the drum,
- wherein the controller is further configured to control the motor to repeatedly rotate and stop while the drum is heated, and
- wherein a sum of times for which the motor is rotated while the drum is heated is greater than a sum of times for which the motor is stopped.
