A method controls a washing machine including a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine. The method includes: controlling a rotation of the drum by operating the washing motor to rotate the drum at a first rotation speed in a first rotation direction, and to maintain a rotation of the drum at the first rotation speed in the first rotation direction so that laundry in the drum maintains contact with an inner circumferential surface of the drum; and controlling a pump speed of the circulation pump by operating a circulation pump motor in the circulation pump to accelerate and decelerate at least once while the washing motor rotates the drum at the first rotation speed in the first rotation direction.

The present specification relates to a clothing treatment apparatus and a control method therefor, the clothing treatment apparatus comprising: a plurality of inverters for controlling the motors of a drum, a compressor, and a blowing fan; a converter for converting input power input from an external source and outputting the converted power to the inverters; and a control unit for controlling the plurality of inverters and the converter.

Disclosed is an artificial intelligence laundry treatment apparatus including a washing tub configured to receive laundry, the washing tub being configured to be rotatable, a motor configured to rotate the washing tub, a controller configured to control the motor such that the washing tub is accelerated to a predetermined target speed at an acceleration gradient of 1.5 to 2.5 rpm/s within a range within which the laundry moves in the washing tub, and a current sensing unit configured to sense current of the motor, wherein the controller is configured to obtain at least one of laundry weight or laundry quality from output of an output layer of an artificial neural network pre-trained based on machine learning using a current value sensed by the current sensing unit during accelerated rotation of the washing tub as input of an input layer of the artificial neural network.

A clothing treatment includes: a cabinet ; a door coupled to the cabinet ; a tub, ; a drum provided inside the tub ; a driving unit for rotating the drum; a gasket, that connectsan entrance of the cabinet toan opening of the tub ; and a water supply unit for supplying water to the tub. The water supply unit is configured to supply water to the tub to a first water level higher than the lowest part ofan inner side surface of the gasket. The driving unitis configured to rotate the drum at a first rotating speed at which a centrifugal force applied to laundry inside the drum is greater than the gravity applied to the laundry, at the first water level.

A laundry appliance includes a cabinet. A drum disposed within the cabinet and has an inner circumferential wall. At least one lifter is operably coupled to the inner circumferential wall of the drum. A motor is operably coupled to the drum and is disposed within the cabinet. A controller is disposed within the cabinet and is communicatively coupled to the motor. A negatively-charged member selectively disposed within the drum. A negative charge is configured to attract oppositely-charged foreign substrates to the negatively-charged member. The negatively-charged member is selectively coupled to the at least one lifter.

A washing machine and method for operating a washing machine having a suds container and a non-ribbed drum. During rotation of the drum in a subcritical rotational speed range, the method includes determining an average value, a minimum, and a maximum of an oscillation of a physical variable relating to the drum or the motor, forming an overall average value from the determined average values, subtracting the overall average value formed from the corresponding minimum determined per oscillation and the corresponding maximum determined per oscillation to calculate a maximum value and a minimum value per oscillation, respectively. In each case an amount is formed from the respective calculated maximum value and an amount is formed from the respective calculated minimum value, a standard deviation from the amounts is determined, and a loading situation where laundry is rolling in the drum is determined based on the determined standard deviation.

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 camera assembly is used to monitor articles for washing within the wash basket. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain a reference image and one or more test images, which utilize image recognition to assess turn-over of the articles for washing during a given wash cycle. When turn-over performance is inadequate, a controller may adjust one or more operating parameters of the wash cycle to improve performance. Turn-over performance of the wash cycle is determined to be adequate once the image recognition process fails to find adequate correlation between the reference image and the test image a predetermined number of times.

A method for controlling a laundry washing machine. The method includes: performing a tub loading process comprising operating supply valve(s) to provide a first volume of water through a detergent supply system and into a tub to fill the tub with wash liquid; performing a washing process comprising rotating a drum to agitate laundry in in the presence of the wash liquid; performing a static rinsing process comprising operating a pump to remove a free volume of wash liquid from the tub without rotating the drum; and performing one or more rinsing processes comprising: operating the supply valve(s) to provide a volume of clean rinse water to the tub, operating the pump to remove the rinse water from the drum, and operating the motor to spin the drum at high speed to extract rinse water from the laundry, while continuing to operate the pump.

A laundry treating apparatus including a drum holding a washing object, a drive unit rotating the drum, a drive controller, a display unit with an input unit accepting drive unit control orders, and a display communicating treating progress of the washing object. The display unit having a controller with an input data processing unit, an output data processing unit, and a processing unit control program for running the input and output data processing units. The laundry treating apparatus further including a system managing unit enabling the drive controller and display unit to exchange data with the display unit controller, ordering operation of the display unit, and running the processing unit control program, a list storage unit storing a program list the display unit controller runs, and a monitoring unit for initializing the system managing unit if the processing unit control program is not at the list storage unit.

A laundry treatment apparatus includes a cabinet having an upper surface, the upper surface being configured to receive an object thereon, a drawer adapted to be drawn from the cabinet, a drum disposed in the drawer and defining a space for receiving laundry, a driving unit configured to rotate the drum, a control unit configured to control the driving unit, and a connector unit configured to impact an ability of the control unit to control operation of the driving unit based on whether or not the object is placed on the upper surface of the cabinet by preventing the control unit from controlling operation of the driving unit based on the object being absent from the upper surface of the cabinet and by allowing the control unit to control operation of the driving unit based on the object being placed on the upper surface of the cabinet.
