A method controls a garment processing device and includes rotating a drum inside a tub at a first rate, measuring a degree of imbalance of laundry while rotating the drum at the first rate, increasing the rate of rotation to a second rate based on a first measurement being less than or equal to a first reference value, rotating the drum at a second rate, measuring the degree of imbalance while rotating the drum at the second rate, stopping rotation of the drum based on a second measurement being less than or equal to a second reference value, accelerating the drum to a third rate higher than the second rate, thereby removing water from the garments, and stopping rotation of the drum based on the degree of imbalance of the drum becoming larger than an imbalance reference value that is set based on the second measured value.

Method for controlling garment processing device

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.

Control method of laundry treating apparatus

A laundry treatment apparatus including a rotatable drum in which laundry is stored, at least three balancers mounted to the drum so as to be spaced apart from one another by the same angle around a rotation center of the drum. Liquid is introduced into and discharged from the balancers via a feeder supplying the liquid and a flow path structure mounted to the drum to guide liquid supplied from the feeder to the balancer located in a direction for removal of unbalance of the drum.
