Abstract: A control method of a laundry treating apparatus includes rotating a drum at a reference rotational speed that is lower or higher than a resonance rotational speed of the laundry treating apparatus; measuring the maximum displacements of tub front and rear surfaces and a phase difference between the maximum displacements during the rotation of the drum at the reference rotational speed; determining a front unbalance (UB) mass located in a drum front area, a rear UB mass located in a drum rear area, and an angle between the UB masses based on the maximum displacements and the phase difference; and accelerating a drum rotational speed to a target rotational speed that is higher than the reference rotational speed and the resonance rotational speed, when the front and rear UB masses are in a preset allowable mass range and an angle between the UB masses is in an allowable angle range.

Abstract: The present disclosure relates to a method for controlling a garment processing device, the method comprising: a foreign-material separating step of rotating a drum rotatably provided inside a tub that stores water such that friction occurs between garments inside the drum and the water; a drain step of discharging the water inside the tub to the outside of the tub; a first maintenance step of maintaining the rate of rotation of the drum, after same has reached a preconfigured first rate, at the first rate; a first measurement step of measuring the degree of imbalance occurring in the drum while the drum rotates at the first rate; a second maintenance step of increasing the rate of rotation of the drum to a predetermined second rate, if a first measured value measured in the first measurement step is equal to/below a preconfigured first reference value, and then maintaining same at the second rate; a second measurement step of measuring the degree of imbalance occurring in the drum while the drum rotates at the second rate; stopping the drum from rotating if a second measured value measured in the second measurement step is equal to/below a preconfigured second reference value; and a dewatering step of accelerating the drum to a third rate configured to be higher than the second rate, thereby removing water from the garments. The dewatering step is stopped if the degree of imbalance of the drum measured during the drum is accelerated to the third rate is larger than a predetermined imbalance reference value, and the imbalance reference value is configured on the basis of the second measured value.
