In addition to the at least one active damper, at least one passive damper can be provided.

A method of controlling a laundry treatment apparatus, the method including: determining whether bubbles have been generated in a tub of the laundry treatment apparatus in a state in which a second washing apparatus of the laundry treatment apparatus is operated based on a sequence of operations; and based on a determination that bubbles have been generated, reducing bubbles by (i) adding at least one first operation to the sequence of operations or (ii) replacing at least one second operation of the sequence of operations, is disclosed.

A control method of a laundry treatment apparatus is disclosed. The control method includes rotating the drum at a predetermined first number of rotations to measure the weight of the laundry stored in the drum (a laundry weight measurement step), rotating the drum at a predetermined second number of rotations to determine the magnitude of the dynamic unbalance of the drum (an unbalance measurement step), accelerating the drum to a target number of rotations, which is greater than the first number of rotations and the second number of rotations, when the magnitude of the dynamic unbalance measured at the unbalance measurement step is less than a predetermined reference value (an acceleration step), interrupting the rotation of the drum when the variation per unit time of current supplied to the stator during execution of the acceleration step is equal to or greater than a predetermined reference variation (a first interruption step), rotating the drum at the first number of rotations to determine the weight of the laundry stored in the drum (a laundry weight remeasurement step), and interrupting the rotation of the drum when the deviation between the laundry weight measured at the laundry weight remeasurement step and the laundry weight measured at the laundry weight measurement step is equal to or greater than a predetermined reference deviation (a second interruption step).

A method for controlling a laundry treating apparatus is disclosed. The apparatus comprises a main-drum and an auxiliary-drum selectively mounted on or separated from the main-drum. The method may comprise: a main laundry quantity detection operation for detecting a laundry quantity in the main-drum via rotation of a pulsator disposed in the main-drum; and an auxiliary laundry quantity detection operation for detecting a laundry quantity in the auxiliary-drum by driving the main-drum, wherein the auxiliary laundry quantity detection operation is performed based on the main laundry quantity detected in the main laundry quantity detection operation.

A method may be provided for controlling a laundry treating apparatus. A first speed rotating may control the drum to accelerate the drum to rotate at a first speed, a braking may apply a brake to stop the drum, a second speed accelerating may accelerate the drum to a second speed, a current sensing may sense a current being applied to the motor during the drum is accelerated to the second speed, and a laundry amount determining may determine a laundry amount based on the current sensed in the current sensing.

A washing apparatus and a control method thereof using an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a 5G environment connected for Internet of things (IoT) is provided. The washing apparatus including a container in which laundry is accommodated includes a controller, a motor electrically connected to the controller and configured to rotate the container, a weight sensor electrically connected to the controller and configured to measure a weight of the laundry accommodated in the container, and a vision sensor electrically connected to the controller and configured to photograph the laundry accommodated in the container.

A compact washing machine capable of improving detergency or reducing a washing time is provided. A drum 30 may be rotatably installed in a tub 20 installed in the inside of a housing 10 in the state in which an opening 12 is toward an opening of the drum 30. A pulsator 40 having a protrusion 45 extending in a radial direction may be rotatably installed on a bottom of the drum 30. During washing operation, a controller 60 may control a driving device 50 to rotate the pulsator 40 and the drum 30 in opposite directions.

A method is provided for controlling a laundry treating apparatus. The method may include controlling the drum to accelerate the drum to rotate at a first speed, applying a brake to stop the drum, accelerating the drum to a second speed, sensing a current being applied to the motor while the drum is accelerated to the second speed, and determining a laundry amount based on the sensed current.

A method for controlling a laundry treating apparatus is disclosed. In a washing step, the presence or absence of entangled laundry is detected using at least one of a vibration value of a drum, a current value applied to a drive unit, and an RPM value of the drum, and a step of untangling the entangled laundry is performed using at least one of a vibration value of a drum, a current value applied to a drive unit, and an RPM value of the drum.
