Abstract
A washing machine according to an aspect of the disclosure includes: a drum; a tub accommodating the drum and storing water; a drum motor configured to provide a rotation force to the drum; a water supplier configured to supply water to the tub; a hot air supplier configured to supply hot air to the drum; a current sensor configured to output a current signal corresponding to a magnitude of current applied to the drum motor; and a controller configured to perform a washing operation while controlling the water supplier and the drum motor, and perform a drying operation while controlling the hot air supplier and the drum motor.
Claims15
A washing machine with a drying function comprising:
- a drum to receive an object, the drum being rotatable;
- a tub to accommodate the drum and to receive water;
- a drum motor configured to provide a rotation force to the drum, for the drum to rotate within the tub;
- a water supplier configured to supply the water to the tub;
- a hot air supplier configured to supply hot air to the drum;
- a current sensor configured to output a current signal based on a magnitude of current applied to the drum motor to rotate the drum;
- and
- a controller configured to perform
- a washing operation while controlling the water supplier and the drum motor, and
- a drying operation while controlling the hot air supplier and the drum motor,
- wherein the controller is configured to
- determine a dryness of the object, accommodated in the drum, based on the current signal received while performing the drying operation,
- obtain an average measurement value corresponding to the dryness of the object by calculating an average of a plurality of measurement values measured during a preset time period,
- compare a first average measurement value with a second average measurement value obtained in succession to the first average measurement value,
- determine an event is generated based on a determination that the second average measurement value is greater than or equal to the first average measurement value, and
- control the hot air supplier based on the number of times by which the event is generated.
A method for controlling a washing machine with a drying function, the washing machine including a drum to receive an object, the drum being rotatable, a tub to accommodate the drum and to receive water, a drum motor configured to provide a rotation force to the drum, for the drum to rotate within the tub, a water supplier configured to supply the water to the tub, a hot air supplier configured to supply hot air to the drum, and a current sensor configured to output a current signal based on a magnitude of current applied to the drum motor to rotate the drum, the method comprising:
- performing a washing operation while controlling the water supplier and the drum motor;
- performing a drying operation while controlling the hot air supplier and the drum motor;
- determining a dryness of the object, accommodated in the drum, based on the current signal received while performing the drying operation;
- obtaining an average measurement value corresponding to the dryness of the object by calculating an average of a plurality of measurement values measured during a preset time period;
- comparing a first average measurement value with a second average measurement value obtained in succession to the first average measurement value;
- determining an event is generated based on a determination that the second average measurement value is greater than or equal to the first average measurement value;
- and
- controlling the hot air supplier based on the number of times by which the event is generated.
