The present disclosure relates to a clothing treatment apparatus comprising: a first cabinet forming the outer appearance; a first drum of a cylindrical shape having open front and rear surfaces; a second cabinet located under the first cabinet; a tub located in the second cabinet; a second drum located in the tub to be rotatable and accommodating clothing; a first air suction duct for sucking the air in the first drum; a second air suction duct for sucking the air in the tub; a connection duct connected to the first air suction duct and the second air suction duct and including a heat exchanger for exchanging heat with the sucked air; a first exhaust duct for discharging the air, which has exchanged heat via the heat exchanger, to the first drum; and a second exhaust duct for discharging the air, which has exchanged heat via the heat exchanger, to the tub.

A lint filter assembly (40) for a household appliance (10) has a housing (42) that couples with duct work (38) of the appliance (10). A lint catcher (44) is receivable in the housing (42). The lint catcher (44) collects lint as it is moved through the duct work (38). A mechanism (90) is coupled with the lint catcher (44) so that a user pushes the lint catcher (44) into the housing (42) for a first filtering position. The lint catcher (44) is positively locked in place by the mechanism (90). The lint catcher (44) is moved to a second cleanout position, releasing the positive lock, so that lint can be removed from the lint catcher (44).

A washing machine with drying function includes a cabinet, a tub inside the cabinet, and provided with a front opening to allow laundry to be introduced and removed and a back opening, a drum rotatable inside the tub. A heated air supplying device which includes a heat exchange part, an inlet duct disposed at one side of the tub, and formed to guide air that is introduced from a rear side of the heated air supplying device toward the heat exchange part, a supply duct disposed at another side of the tub, and formed to guide air that passed the heat exchange part to be discharged to a front side of the heated air supplying device, and a fan at a front side the tub, and configured to cause an airflow such that air being discharged from the supply duct is supplied to the front opening of the tub.

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.

Listed are some of this invention's unique features for producing a healthier home and a safer clothes dryer vent within the same housing system, which may be installed within a typical wall system or as a free-standing unit in a laundry room.

Included are two airflow receiving ports that accepts airflow from a clothes dryer or optionally from a house's interior rooms and two airflow exhaust ports that discharge the same airflow into an exhaust pipe to the outside or optionally into the building interior as recycled airflow.

A drainage device removes water derived from condensate which forms in the exhaust pipe and otherwise flows back into the housing.

Two (2) receiving ports and the two (2) exiting ports combine to provide four (4) combinations of airflow management.

The choice of which of the four (4) airflow ports are activated for airflow passage is subject to a selection from a control system which contains switches for the desired airflow management thru the housing.

Additionally, the control system contains monitors and sensors to indicate unsafe temperatures, air pressure changes or filter blockage within the housing.

A shutdown mechanism within the control system stops the airflow exhaust fan and stops the clothes dryer to provide an additional measure of safety.

Included in the invention is a multi-filter filtration system that includes filters that block lint particulate from a clothes dryer and block indoor pollutants comprising pre-filters, True HEPA filters, with activated carbon filters and air cleaners to meet EPA Indoor Air Quality Standards and MERV Ratings.

A multi-speed airflow exhaust fan moves airflow in thru the receiving ports, thru the multi-filters and out thru the exiting ports. Additionally, within the housing, access openings with removable windows provide internal inspections and accessibility.

In conclusion the elements of this invention combine to improve the efficiency and safety of a clothes dryer's exhaust system and improve the indoor air quality of a home or commercial building.
