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

Provided is a control method for a laundry treating apparatus comprising: a drum in which laundry is stored; at least three balancers fixed to the drum and provided to be spaced from each other at the same angle with respect to the rotational center of the drum; front spaces provided in each balancer and positioned at the front of the drum; and rear spaces provided in each balancer and positioned at the rear of the drum, wherein the control method for the laundry treating apparatus comprises: a rear control step of supplying a liquid to at least one of the rear spaces so as to increase the weight of a quadrant (first target quadrant) positioned in the direction opposite to a quadrant, of a circumferential surface of the drum, to which a force causing unbalance is directed; and a front control step of supplying a liquid to at least one of the front spaces so as to increase the weight of a quadrant (second target quadrant) positioned in the direction opposite to the quadrant, of the circumferential surface of the drum, to which the force causing unbalance is directed.

Clothes-handling apparatus and method for controlling clothes-handling apparatus

The present invention relates to a washing machine which comprises: a cabinet having a first insertion hole; a tub provided in the cabinet and having a second insertion hole aligned with the first insertion hole; a cabinet door provided to the cabinet, for opening and closing the first insertion hole; a tub door provided to the tub, for opening and closing the second insertion hole; a hinge unit for elastically supporting the tub door in the opening direction of the second insertion hole; and an antifriction member provided on one surface among the surfaces where the tub door and the cabinet door face each other, for preventing a direct friction between the tub door and the cabinet door. Accordingly, the present invention prevents the vibration and noise from the tub from being transmitted to the cabinet and may increase the capacity of the tub. In addition, when opened and closed, the cabinet door for opening and closing the cabinet and the tub door for opening and closing the tub operate in association with each other, thereby being capable of giving convenience to a user.
