摘要： A washing machine appliance may include a cabinet, a tub, a wash basket, and a controller. The tub may be positioned within the cabinet. The tub may define a tub outlet and a tub inlet. The wash basket may be rotatably mounted within the tub. The wash basket may define a chamber for receipt of articles for washing. The controller may be mounted to the cabinet and configured to initiate a washing operation. The washing operation may include flowing a volume of liquid to the tub, initiating a spin phase requiring rotation of the wash basket following flowing the volume of liquid to the tub, determining an out-of-balance (OOB) state within the wash basket, determining a user OOB preference following determining the OOB state, and adjusting the spin phase according to the determined user OOB preference.

摘要： A method for redistributing a laundry load in a drum of a washing machine in order to reduce the unbalance generated to the nonuniform distribution of said laundry load in said drum. The method comprises: generating a sinusoidal motor speed profile (RS(t)), controlling the electric motor based on the sinusoidal motor speed profile (RS(t)), estimating unbalance value indicative of the unbalance of load in the laundry drum, estimating an inertia value indicative of the inertia of the load in the laundry drum, varying the amplitude of the sinusoidal speed profile (RS(t)) based on estimated unbalance value and inertia value, and controlling said electric motor based on modified sinusoidal motor speed profile.

摘要： 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.

摘要： A laundry treating apparatus includes a cabinet, a tub, a drum, a water supply, a drain, a rotator rotatably disposed on a bottom surface of the drum, and a controller that controls rotation of the rotator. The rotator includes a bottom portion positioned on the bottom surface, a pillar protruding from the bottom portion toward an open surface, and a blade including a plurality of blades disposed to be spaced apart from each other along a circumferential direction of the pillar. The blade extends from the bottom portion toward the open surface in an inclined direction with respect to a longitudinal direction of the pillar. The rotator performs a first rotation for generating an ascending water flow and a second rotation for generating a descending water flow. The controller controls the rotator to alternately repeat the first rotation and the second rotation.

摘要： A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A motor assembly selectively rotates the wash basket, a drain pump assembly selectively drains wash fluid from the wash tub, and a camera assembly is used to monitor an out-of-balance value to minimize out-of-balance issues. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain one or more images of the wash chamber, analyze the one or more images using a machine learning image recognition process to determine the out-of-balance value of the load of clothes in the wash basket, and perform a cloth redistribution process based at least in part on determining that the out-of-balance value is greater than a predetermined out-of-balance threshold.

摘要： A washing machine is provided. The washing machine includes a tub, a drum rotatably arranged within the tub, a drum motor for rotating the drum, a vibration sensor for sensing the vibration of the tub, and a control unit which maintains the rotation speed of the drum motor on the basis that the sensing value of the vibration sensor reaches a certain predetermined value during a dehydration operation, and which continuously maintains or increases the rotation speed of the drum motor based on the variation value of the sensing value of the vibration sensor.
