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 laundry treatment apparatus includes: a housing defining a reception space, a first through-hole in communication with the reception space and defined at a first surface of the housing, a second through-hole in communication with the reception space and defined at a second surface facing the first surface, a driver including (i) a driving shaft rotatably fixed to the second through-hole and defining a concentric shaft and (ii) a motor configured to rotate the driving shaft, a connection shaft fastening portion disposed at the driving shaft, defining a space, and configured to transmit rotational motion of the driving shaft, and a support configured to be elastically deformed between a second connection body and the second surface and configured to press the second connection body toward the first connection body such that the first connection body is coupled to a fastening body.

Laundry treatment apparatus

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

Disclosed is a laundry treatment apparatus including a balancer capable of active control. The laundry treatment apparatus includes a cabinetwith a laundry feeding hole formed therein, a tubprovided within the cabinet and for holding washing water, a drumrotatably installed around a rotation axis which may be forward inclined within the tub for holding laundry, a driving unitto rotate the drum, a balancerdisposed in the drum and having an internal space therein, wherein water is selectively introduced into the internal space of the balancer when the drum is rotated, a centrifugal channel devicedisposed on the backside of the drum, rotated along with the drum, and having an opening portion formed toward a back direction so that water is supplied to the opening portion and guided into the internal space of the balancer, and a nozzledisposed at the back of the drum, spaced apart from the drum, to spray water toward the opening portion.

Disclosed herein is a laundry treatment apparatus including balancers. The laundry treatment apparatus includes a cabinetwith a laundry feeding hole formed therein, a tubprovided within the cabinet and for holding washing water, a druminstalled within the tub for holding laundry, a driving unit to rotate the drum, a plurality of balancerseach having an internal space formed in the balancer in which water is received, the plurality of balancers spaced apart from each other on the circumference of the drum, and an inflow channel deviceto selectively guide water from the outside of the drum to the internal spaces of the plurality of balancers when the drum is rotated.

Disclosed is a laundry treatment apparatus including a cabinet defining an external appearance of the laundry treatment apparatus, a drum rotatably provided inside the cabinet, the drum being configured to accommodate laundry therein, a drive unit configured to generate torque required to rotate the drum, a power transmission unit provided on one surface of the drum, the power transmission unit being configured to transmit the torque generated by the drive unit to the drum so as to rotate along with the drum, and at least one balancer provided on an inner circumferential surface of the drum. Water is selectively supplied into the balancer so as to eliminate unbalance occurring in the drum, and the balancer has a shorter length than a longitudinal length of the drum.
