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： The present disclosure relates to a laundry treatment machine. A drain laundry treatment machine according to an embodiment of the present disclosure: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a drain motor; an output current detector to detect an output current flowing in the drain motor; and a controller to control the drain motor to rotate at a speed lower than a first speed when the output current flowing in the drain motor decreases in a state where a speed of the drain motor is the first speed. Accordingly, it is possible to reduce a pressure in a vortex chamber of the drain pump during dewatering.

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 includes a first washing compartment to hold a first set of articles to be washed and a second washing compartment to holds a second set of articles to be washed, the second washing compartment having an inserted position and a removed position. A liquid flow valve is configured to connect to an external liquid source to selectively control flow of liquid from the external liquid source and into one or more of the first washing compartment and the second washing compartment. An electric motor is configured to rotate the first washing compartment, and the second washing compartment, when the second washing compartment is in the inserted position. A controller, in communication with the electric motor, determines a mass of the second set of articles and then determines, as a function of the determined mass, a volume of water to be added to the second washing compartment.

摘要： A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a motor and a rotatable basket. The motor is operated to rotate the basket to a first speed. The basket is then decelerated from the first speed to a second speed less than the first speed. A deceleration time is determined while decelerating the basket from the first speed to the second speed. The method may include, or the washing machine appliance may be configured for, determining a size of a load of articles in the basket of the washing machine appliance based on the deceleration time. Based on the determined size of the load, one or more operating parameters of the washing machine appliance are selected and an operation of the washing machine appliance is performed according to the one or more selected operating parameters.
