A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

Systems, apparatuses and methods for easily modifying and using a laundry washing machine to recirculate water and spray wash water and cleaning compositions onto textiles in order to optimize water usage, wash temperature, and composition dosage are provided. An apparatus comprising a replacement door window, a spray nozzle, a pump, tubing, and connectors for use in the modified laundry washing machine is further provided. The modification system provides improved cleaning performance and effective cleaning even in low water conditions.

A control method includes performing a first drum operation of supplying water by a first set amount together with a detergent into the tub and rotating the drum at a first drum rotation speed while water is supplied, operating the pump at a first pump rotation speed during the first drum operation, operating a heater to heat water in the tub, performing a second drum operation of rotating the drum at the first drum rotation speed during the operation of the heater, and operating the pump at a second pump rotation speed at least once during the second drum operation, stopping the operation of the heater, performing a third drum operation of rotating the drum at the first drum rotation speed, and operating the pump at the first pump rotation speed during the third drum operation.

A laundry washing machine comprising a cabinet supporting a washing tub external to a washing drum adapted to receive laundry and a liquid supply line for supplying liquid into the washing tub/drum through a nozzle having a tubular portion and a sprayer portion comprising a bent zone. The nozzle comprises an obstruction arranged upstream of the bent zone.

A method of controlling a washing machine that includes a tub, a drum rotatably disposed in the tub, at least one nozzle spraying water into the drum, a washing motor rotating the drum relative to the tub, and a circulation pump circulating water discharged from the tub, the method including: rotating the drum to cause laundry in the drum (i) to be raised with respect to a bottom of the drum and (ii) to fall downwards into the drum while water is supplied to the drum; spraying water through the at least one nozzle while the drum rotates; based on a first water level in the tub, controlling the circulation pump to rotate at a first rotation speed; supplying water to the drum to increase the water in the tub to a second water level; and controlling the circulation pump to rotate at a second rotation speed.

The present disclosure relates to a method of controlling a laundry treating device comprising a tub configured to store wash water therein, a drum rotatably disposed within the tub to receive laundry therein, a heater configured to heat the wash water supplied to the tub, a circulating pump configured to circulate the wash water supplied to the tub, and a controller configured to control the tub, the drum, the heater, and the circulating pump. The method comprises detecting an amount of laundry received in the drum, supplying the wash water to the tub based on the amount of laundry, and soaking the laundry by operating the circulating pump. The step of soaking the laundry is selectively progressed based on the amount of laundry detected.

A control method of a washing machine including a drum rotated about a horizontal rotation axis in a tub and a plurality of nozzles spraying water discharged from the tub and circulated by a pump into the drum, includes (a) step of performing a first drum operation of supplying water by a first set amount together with a detergent into the tub and rotating the drum at a first drum rotation speed, while water is supplied, at least once and operating the pump at a first pump rotation speed at least once during the first drum operation; (b) step of performing a second drum operation of operating a heater to heat the water in the tub in a state in which the first set amount of water is supplied into the tub, rotating the drum at a first drum rotation speed at least once during the operation of the heater, and operating the pump at the first pump rotation speed at least once during the second drum operation; (c) step of rotating the drum at a preset spin-drying speed to spin-dry laundry; and (d) step of operating the drum at a second drum rotation speed greater than the first drum rotation speed, while supplying water into the tub, after the operation of spin-drying the laundry, and accelerating the pump from the second pump rotation speed to a third pump rotation speed.

A washing machine is provided that includes a washing tub, a driver to rotate the washing tub, a sensor to sense an operation of the washing machine, and at least one processor configured to obtain a weight of dry fabric of laundry in the washing tub, control the driver to rotate the washing tub at a speed within a first range, and obtain a first torque axis current of the driver. The at least one processor is further configured to, after supplying washing water to the washing tub, control the driver to rotate the washing tub at a speed within a second range and obtain a second torque axis current of the driver, and identify a material of the laundry by inputting at least one of the weight of the dry fabric, the first torque axis current, or the second torque axis current to a neural network model.

A method of controlling a washing machine includes: sensing a laundry amount accommodated in a drum; performing water supply into the drum according to the sensed laundry amount; rotating a pump motor at a certain initial rotation speed and transferring washing water discharged from the drum to at least one nozzle for spraying water into the drum; sensing a water level in the drum; performing a re-supply of water at least once until the sensed water level reaches a set water level; and increasing the rotation speed of the pump motor whenever the re-supply of water is performed, so that as the rotation speed of the pump motor is increased, the reaching range of the water stream sprayed through the nozzle gradually expands from the lower side of the circumferential surface of the drum to the rear surface of the drum.

A method of controlling a washing machine. The washing machine includes a tub configured to receive water, a drum rotatably disposed in the tub, a volute pump including (i) an impeller configured to rotate in one or more directions to pump water discharged from the tub and (ii) a pump housing that defines a volute-shaped passage configured to guide water pumped by the impeller, and a circulating water supply device configured to supply water discharged from an outlet port of the volute pump into the drum. The method includes: supplying water and detergent into the tub; and rotating the impeller of the volute pump in a first direction to discharge a first amount of water from the volute pump, the first amount of water being less than a second amount of water discharged from the volute pump based on the impeller being rotated in a second direction.
