The present invention relates to a device for handling laundry and a control method thereof, wherein the device for handling laundry, equipped with a plurality of washing units that wash independently of one another, sets a washing course in order that, when washing is being carried out by a first washing unit and a second washing unit at the same time, a specific operation is not carried out by the first washing unit and the second washing unit at the same time, the washing course being set by combining the washing courses of the plurality of washing units, and thus, operational delays resulting from simultaneous operation are prevented, vibrations are reduced, momentary increases in power consumption are prevented, protecting the device for handling laundry and improving energy consumption efficiency.

A computer is used to obtain arrival time required for a user of a washing machine to arrive at an installation position of the washing machine based on a position of the user and the installation position, and when it is determined that the washing machine is performing washing based on operation information of the washing machine, when the arrival time is longer than washing completion time required for the washing machine to complete washing, to transmit instruction infomiation for adding a process of soaking laundry in water by the washing machine or for changing time in the process to the washing machine.

A control method for a laundry treating apparatus comprises a washing machine power supply step of supplying a power to a washing machine interface provided to receive a control command; a course execution step of executing a washing course by the washing machine if the washing course is input to the washing machine interface; a dryer power supply step of supplying the power to the dryer if a preheating request signal is input through the washing machine interface; and a preheating step of including a supply stroke of supplying the air to the drying drum and a heating stroke of heating the air supplied to the drying drum.

The present disclosure relates to a laundry treatment machine. According to an embodiment of the present disclosure, a laundry treatment machine includes a controller controlling a motor, during dewatering, to be driven at a first speed when a lift is at a first level and to drive the motor at a second speed greater than the first speed when the lift is at a second level greater than the first level, wherein the lift is a difference between a water level of a water introduction part through which water flows into a drain pump and a water level of a water discharge part through which the water is discharged out of the drain pump. Accordingly, noise or vibration can be reduced even if the lift is changed during the dewatering.

A method of operating a laundry treating appliance with a combination washer/dryer having a cabinet defining an interior, a tub located within the interior, and a rotatable drum located within the tub interior and defining a treating chamber, and an air recirculation conduit, the method comprising supplying water to the treating chamber, rotating the drum, and draining the water from the laundry treating appliance.

A drum type washing machine capable of realizing weight reduction and improvement in washing performance at low cost is provided. A drum type washing machine is disclosed. A pulsator is installed rotatably at a bottom of the drum rotatably accommodated in a tub. A motor configured to rotate forward and backward rotationally drives the drum and the pulsator. A control device executes a washing mode in which the motor is driven at a low rotation and a spinning mode in which the motor is driven at a high rotation. The pulsator and the drum have different velocity ratios. A second drive transmission element of the pulsator includes a clutch. Based on executing the washing mode, the drum is rotationally driven while the pulsator is rotationally driven or is allowed to idle. Based on executing the spinning mode, the drum is rotationally driven while the pulsator is allowed to idle.

The present invention relates to a laundry treating apparatus. The laundry treating apparatus according to an embodiment of the present invention includes a control unit which controls the tub to rotate at a first speed in a case of a blanket dehydration mode, to rotate at a second speed lower than the first speed so that the plurality of balls are dispersed when amount of eccentricity in the first speed rotation is equal to or greater than a first reference value, and to rotate at a third speed higher than the first speed when the amount of eccentricity in the first speed rotation is less than the first reference value. Accordingly, in a blanket dehydration mode, it is possible to stably perform dehydration by preventing the plurality of balls from operating unbalanced.

Disclosed is a method of controlling a laundry treating apparatus comprising a tub configured to hold wash water, a drum mounted in the tub, a pulsator mounted in the drum, a sub-drum coupled to the drum, the sub-drum being configured to hold wash water, and a drive unit configured to rotate the drum and the pulsator. The method comprises a water current forming step comprising performing a basket motion and a pulsate motion and a cooling step comprising lowering the temperature of the drive unit. The basket motion is configured to form water current in the wash water held in the tub and in the sub-drum simultaneously. The pulsate motion is configured to form water current in wash water held in the drum while the pulsator is driven. A performance timing of the cooling step is preset in at least one of the wash cycle or the rinse cycle.

The laundry treating device has a user interface configured to receive a user selection of a preprogrammed wash cycle. A treating chemistry dispenser has multiple treating chemistry cups configured to dispense treating chemistry to the treating chamber during the selected washing cycle. A controller configured to activate dispensing from each of the treating chemistry cups at preprogrammed times during the wash cycle. A performance enhancement selector configured to receive a user selection such that activation of the performance enhancement selector causes the controller to dispense one of the treating chemistry cups at a different time than the preprogrammed time during the wash cycle.

The present disclosure is to deal with a case in which waterproof clothes, etc. are included in laundry. A washing machine 1 having a dehydration function may include a drum 20 rotatably accommodated in a tub 10, a water-level sensor 60 configured to detect a water level of water IW collected between the tub 10 and the drum 20, a circulation pump 80 configured to supply water to the inside of the drum 20 and to circulate water collected in the inside of the tub 10, and a control apparatus 70 configured to perform a dehydration process. The control apparatus 70 may include a dehydration course decider 74 configured to decide a dehydration course based on a change in water level of water IW collected between the tub 10 and the drum 20 by driving of the circulation pump 80.
