A method for operating a laundry machine having a rotatable drum a tub enclosing said drum; a water supply; a control unit a laundry treatment agent dispensing device configured to hold and deliver at least one of a laundry detergent and a laundry softener; and a control system configured to provide a softener signal that alternately assumes a first value indicating that no laundry softener will be delivered, and a second value indicating that laundry softener will be delivered. The method comprises: performing a washing phase in which detergent is delivered into the tub; and performing a number of rinsing phases wherein detergent from the washing phase is removed using water from said water supply apparatus, wherein the control unit sets the number of rinsing phases according to whether the softener signal assumes the first value or the second value.

A server, a washing machine, and a washing system including the same are provided. The washing system includes a washing machine and a server configured to receive turbidity information of washing water from the washing machine at pre-set time intervals, identify an amount of change in turbidity information of the washing water for the pre-set time intervals based on the received turbidity information, predict turbidity information of the washing water based on the amount of change in turbidity information of the washing water, and transmit a control signal for controlling a washing cycle of the washing machine based on the predicted turbidity information of the washing water.

A method of operating a laundry treatment apparatus includes receiving a tangle-free selection signal corresponding to a tangle-free option distinct from a default option, adjusting one or more parameters of an agitation cycle according to the tangle-free option in response to receiving the tangle-free selection signal, and initiating a washing operation incorporating the one or more adjusted parameters.

The present invention relates to home appliances treating the laundry or object received therein using artificial intelligence. Specifically, the home appliance may include an artificial intelligence-based laundry washing machine that recognizes a load based on vision and automatically provides a specific course. The home appliance include a processor configured to: obtain a learning result from a learning operation using image information previously acquired using the camera and treatment information previously acquired from user interface; and process image information currently acquired using the camera with respect to the learning result, thereby to generate and set current treatment information; and control the home appliance to treat the object based on the set current treatment information.

A method of controlling a washing machine that includes 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 including: operating the washing motor to rotate the drum in a first rotational direction while repeatedly alternating between an acceleration and a deceleration of the drum so that laundry in the drum alternates between maintaining contact with an inner surface of the drum during acceleration, and separates from the inner surface of the drum during deceleration; and operating a circulation pump motor in the circulation pump, while the drum rotates in the first rotational direction, to accelerate a pump speed of the circulation pump during the acceleration of the drum, and to decelerate the pump speed during deceleration of the drum.

A method of controlling a laundry treatment apparatus includes: 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.

A laundry washing machine and method utilize a fluid property sensor to dynamically select between different types of rinse operations, e.g., fill rinse operations or spin rinse operations, performed during a wash cycle.
