The washing machine (11) comprises a container (13) for receiving the items (12) to be washed, and said container (13) is arranged with an inlet connected to the reservoir (20), so that the items (12) are washable inside the container (13) with the purified water. The system (10) further comprises a tank (24) for collecting used water from the container (13), wherein an inlet of the tank (24) is connected to an outlet of the container (13). The system (10) also comprises a sediment filter (28) for filtering off particulate solids from the used water, wherein the sediment filter (28) is arranged between the tank (24) and the water purification apparatus (19).

The invention relates to a program-controlled apparatus (1) for washing items that is equipped with a water purification system (8) for purifying the wash liquor by removing detergent and suspended soil, which purification system (8) utilizes addition of flocculant, wherein the amount of flocculant that is added is controlled to minimize the total amount of flocculant used without compromising the efficacy of the purification treatment.

A laundry appliance includes a wash tub disposed within a cabinet. A rotating drum is disposed within the wash tub. A drain system directs a fluid from the wash tub to a fluid pump. A trap is disposed within a tub drain of the wash tub. The trap includes an elongated body having a plurality of fingers that extend across an aperture defined within the elongated body. The plurality of fingers are configured to permit passage of particulate material and prevent passage of foreign objects through the elongated body.

The disclosure involves a method of removing microfibers in washing liquid during a washing phase of a machine and a machine comprising a washing unit for washing items by means of at least one washing liquid and a washing controller for controlling the operation of the machine at least during washing phaseperiods. The methodcomprises filling (S110) the washing unit with washing liquid to a predetermined level, filtering (S120) by recycling the washing liquid being used through a microfiber filtering unit during a washing phase period at least once, and emptying(S130) the washing unit of washing liquid at the end of the washing phase period.

An air filtration system for a laundry apparatus comprises an air-lint inlet forming an interior volume configured to fluidically couple to a tumbler of the laundry apparatus and extending to an end portion. The system further comprises a lint-collection reservoir coupled to the air-lint inlet configured to hold a liquid at a level, wherein the air-lint inlet extends into the lint-collection reservoir. The system further comprises an outlet conduit in fluid connection with the air-lint collection reservoir. The outlet conduit is configured to expel filter air from the air-lint collection reservoir.

A laundry appliance includes a rotating drum and a door providing access to the rotating drum. A blower directs process air through an air path that includes the drum. A heat exchanger within the air path dehumidifies the process air. A first lint filter within the air path is forward of the drum and below the door. A second lint filter within the air path is downstream of the first lint filter and forward of the heat exchanger. The first and second lint filters capture lint from the process air upstream of the heat exchanger. The first lint filter is angled with respect to the second lint filter. A filter spray system has a plurality of fluid sprayers that deliver fluid to the first and second lint filters, respectively. Each fluid sprayer directs captured lint from the first and second lint filters to a common drain channel.

The present disclosure provides a method of controlling a laundry treating apparatus including a tub in which a drum accommodating clothing is rotatably disposed, a heat exchanger configured to perform heat exchange between air discharged from the tub and a refrigerant in a circulation flow path through which the air circulates, a filter configured to filter the air, a first cleaning mechanism configured to apply cleaning water to any one of the filter and the heat exchanger, and a second cleaning mechanism configured to apply the cleaning water to the other of the filter and the heat exchanger. The method includes measuring a flow rate while supplying water into the tub, and controlling, based on the flow rate, a first flow path control valve for regulating water supply to the first cleaning mechanism and a second flow path control valve for regulating water supply to the second cleaning mechanism.

A fluid delivery system for a laundry appliance includes a blower that delivers process air along an airflow path. A drum receives process air to dry laundry. A heat exchanger dehumidifies the process air and removes condensate therefrom. A drain channel receives condensate from the heat exchanger. A pump directs fluid from the drain channel and along a fluid path. The fluid at least partially includes the condensate. A fluid diverter valve receives the fluid from the pump and selectively and delivers the fluid sequentially to a plurality of spray nozzles that direct a flow of the fluid onto a lint filter and toward the drain channel and a fluid outlet.

A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.

A condensation-based clothes dryer includes a box body, a drum, a front hot air duct, a rear hot air duct, an air chamber, a fan, a motor, a heater, a master control board and a condenser; where the rear hot air duct, the drum, the front hot air duct and the air chamber are communicated, an inlet end of a condensation air duct of the condenser is communicated with an air outlet in the box body, and an outlet end of the condensation air duct is communicated with outside air, an inlet end of a cooling air duct of the condenser is communicated with outside air, and an outlet end of the cooling air duct is communicated with an air inlet in the box body, and a condensate water collecting box is arranged below the condenser.
