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.

A clothes management apparatus includes a main body including a clothes management compartment, and an upper garment hanger disposed in the clothes management compartment to hang an upper garment. The upper garment hanger includes an inward discharge port to discharge air to the inside of the upper garment and the main body includes an outward discharge port to discharge air to the outside of the upper garment, so that the outside and inside of the upper garment may be managed simultaneously.

A microbubble generator and a laundry treating device. The microbubble generator includes: an air dissolving tank, having an air dissolving cavity defined therein, and an inlet and an outlet configured to allow water to flow in and out, the inlet being located above the outlet; a baffle, provided in the air dissolving tank, at least partially located between the inlet and the outlet in a horizontal direction, and provided with a gap and/or a through hole; and a cavitator, provided outside the air dissolving tank and connected with the outlet, or provided at the outlet.

A washing machine and a method of controlling the washing machine are provided. The washing machine includes a display configured to display a washing course and a first washing option set corresponding to the washing course, an inputter configured to receive a user's option change command for changing at least one washing option among a plurality of washing options included in the first washing option set from a user, a storage configured to store a washing option set including the changed at least one washing option, and at least one processor configured, based on the storage of the washing option set being more than a predetermined number of times, to control the first washing option set to be changed to a second washing option set based on the changed at least one washing option.

A water ozonation system (18) that receives source water (16) from a water source (14) and converts it to ozonated water (20) for use in a washing machine (12) includes a system body (30), an ozone generator (38), a sensor assembly (21), and a controller (46). The system body (30) receives the source water (16) from the water source (14). The ozone generator (38) is configured to generate ozone. The ozone generator (38) is coupled the system body (30). The sensor assembly (21) is also coupled to the system body (30). The sensor assembly (21) is configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition. The controller (46) receives the at least one electronic data signal from the sensor assembly (21) and regulates a level of ozone that is generated by the ozone generator (38) based at least in part on the at least one electronic data signal.

A system and a method for treating a textile material with ozone gas. The system includes: an ozone gas supply system, a hollow chamber fillable with ozone provided by said gas supply system, a textile-feeding port connected to said chamber and comprising a first liquid fillable tank, a textile-discharging port connected to said chamber and comprising a second liquid fillable tank, guide rollers, driving rollers, at least one tension compensator located inside the hollow chamber. The system is adapted for implementing the method, the latter including: using the system and providing liquid to said first and second tanks, providing ozone gas to said hollow chamber, driving the textile material to pass tensed through the system while controlling its tension using the tension compensators. The use of the tension compensators prevents the formation of ozone induced defects on the textile material.

A washing machine and method for operating a washing machine having a suds container for holding water, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device. The method allows the execution of a washing program (Wp) having a washing phase (Wa) and/or at least one rinsing phase (Sp), and includes feeding water into the suds container in a first region of the drum in at least one of these phases (Wa, Sp) up to a predetermined water level (h) that is selected such that the laundry floats in the water, and rotating the drum at a predetermined rotational speed such that water is released from a second region of the drum and falls onto the laundry.

A clothes treatment apparatus includes a first case, a second case, a width-direction bracket for coupling at least one of front walls or rear walls of the first case and the second case to each other in a width direction, a depth-direction bracket for coupling at least one of upper walls or lower walls of the first case and the second case to each other in a depth direction, and a height-direction bracket for coupling at least one of the front walls or the rear walls of the first case and the second case to each other in a height direction. At least two of the width-direction bracket, the depth-direction bracket, or the height-direction bracket are configured to fix at least two surfaces of the first case and the second case.
