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 washing machine having a bubble generator includes a bubble spray part provided at an upper side of a tub and configured to discharge bubbles from a top to a bottom inside the tub; a wash liquid jet nozzle provided inside the bubble spray part and configured to jet wash liquid; a blowing fan provided in the bubble spray part and configured to blow air in a direction in which the wash liquid jet nozzle jets the wash liquid; and a porous plate member provided at a front end of the bubble spray part and including a plurality of holes, wherein when the wash liquid jetted from the wash liquid jet nozzle collides with the porous plate member, bubbles are generated.

A washing machine (10) including a wash tub configured by a water tub (13) and a rotary tub (14); a connecting port (21) connected to a water source; a water feeding case (40) connected to the connecting port (21) to receive water from the water source and containing a detergent storing part (42) in which a detergent is stored; a first water feeding port (41) configured to feed water flown into the water feeding case (40) into the wash tub; a minute bubble generator (22) configured to generate minute bubbles in water passing therethrough; a minute bubble water path (B) extending from the connecting port (21) and reaching into the wash tub from the first water feeding port (41) after passing through the minute bubble generator (22) and the detergent storing part (42) inside the water feeding case (40); a tap water path (A) extending from the connecting port (21) to the wash tub without passing through the minute bubble generator (22); a water supplying valve for tap water (31) provided midway of the tap water path (A) and capable of opening and closing the tap water path (A); and a water supplying valve for minute bubble water (32) provided midway of the minute bubble water path (B) and capable of opening and closing the minute bubble water path (B).

A washing machine includes a tub for accommodating a drum; a water supplier configured to supply water to the tub; a turbidity sensor configured to detect turbidity of water in the tub: a circulation bubble device configured to perform a circulation operation of circulating water in the tub and resupplying it to the tub or a bubble supply operation of generating bubbles and supplying them to the tub; and a controller configured to perform a first rinsing cycle when the turbidity of the water in the tub is higher than a first reference value, and control the water supplier so that water containing a softener is supplied to the tub and perform a second rinsing cycle by controlling the circulation bubble device to alternately perform the circulation operation and the bubble supply operation when the turbidity of the water in the tub is lower than the first reference value.

A washing machine includes a water tub storing water, a rotary tub arranged in the water tub, a dissolving area in which a detergent is fed and dissolved, an FB feed-water pathway which includes a fine-bubble generation apparatus allowing generation of fine bubble water and along which water fed from a feed-water source is passed through the fine-bubble generation apparatus to be fed to the dissolving area as fine bubble water, an FB feed-water valve opening and closing the FB feed-water pathway, and a control apparatus controlling opening and closing of the FB feed-water valve. The detergent and the fine bubble water are controllably brought into contact with each other to dissolve the detergent, in a washing course in which the washing machine is operated and during a period when the detergent is dissolved in feed-water.

A washing machine having a bubble generator includes a bubble spray part provided at an upper side of a tub and configured to discharge bubbles from a top to a bottom inside the tub, a wash liquid jet nozzle provided inside the bubble spray part and configured to jet wash liquid; a blowing fan provided in the bubble spray part and configured to blow air in a direction in which the wash liquid jet nozzle jets the wash liquid; and a porous plate member provided at a front end of the bubble spray part and including a plurality of holes, wherein when the wash liquid jetted from the wash liquid jet nozzle collides with the porous plate member, bubbles are generated.
