A system for washing laundry includes a cleaning fluid electrolytic hydrogen nano bubbles generation device for receiving tap water and electrolyzing the tap water to generate nano hydrogen bubbles and nano ion water or alkaline electrolytic water together as a cleaning fluid; a recycled water nano bubbles generation device for receiving tap water and water recycled by the system and generating ozone nano bubbles from the water, and at least one washing machine capable of performing pre-wash, main wash, or rinse. In the pre-wash or rinse, the recycled water nano bubbles generation device supplies the tap water having ozone nano bubbles to each washing machine through a pre-wash or rinse line. In the main wash, the cleaning fluid electrolytic hydrogen nano bubbles generation device supplies the main solution to each washing machine through, a cleaning fluid line.

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 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 including a bubble generator. The washing machine includes a detergent box configured to store a detergent, a detergent box housing configured to accommodate the detergent box therein and a bubble generator to generate bubbles to be supplied and configured to mix water supplied to the detergent box with air.

A washing machine includes a cabinet; an outer basket in the cabinet and configured to contain wash water; an inner basket in the outer basket and configured to accommodate laundry; a water supply valve unit in the cabinet and connected to an external water supply source to receive wash water; a cabinet cover on an upper side of the cabinet and having an input hole for the laundry; and a micro-bubble generator configured to receive wash water from the water supply valve unit, generate micro-bubbles, and supply the micro-bubbles to a washing space. The micro-bubble generator includes a nozzle unit at or near the input hole and configured to generate micro-bubbles by receive wash water in which gas is dissolved or mixed and discharge wash water having the micro-bubbles therein into the inner basket after the micro-bubbles are generated.
