Disclosed is a method for controlling a laundry treating apparatus, wherein the laundry treating apparatus includes: a drum having a laundry storage space defined therein; a duct defining a channel for supplying air discharged from the drum back to the drum; a fan to move air along the duct; a heat-absorber for removing moisture from air introduced into the duct; a heat-emitter disposed inside the duct to heat air passing through the heat-absorber; a water collector for storing therein water discharged from air passing through the heat-absorber; a first filter for filtering air flowing from the drum to the duct; a second filter positioned between the first filter and the heat-absorber and filtering air passing through the first filter; a water discharger having a water storage space defined therein; a water discharger supply pipe for supplying water stored in the water collector to the water discharger; a water ejector for ejecting water into at least one of the second filter or the heat-absorber; a water ejector supply pipe for supplying water stored in the water collector to the water ejector; a water supply pipe constructed to connect the water discharger and the water collector to each other; a water supply valve for controlling opening and closing of the water supply pipe.

A laundry treating appliance and method for operating a laundry treating appliance having a housing; a treating chamber located within the housing. A duct fluidly coupling the treating chamber to an exterior of the housing with a vent located within the duct. The vent moveable between an open position where a fluid flow passes freely between the treating chamber and the exterior and a closed position where the treating chamber is fluidly isolated from the exterior.

A dryer apparatus is disclosed comprising a container having a container inlet and outlet, a pump that is configured to motivate a first air-vapor mixture flow via the container inlet and via the container outlet, a heating device configured to heat the first air-vapor mixture, a selector with at least two states, a compressor that is configured to compress and motivate a part of the first air-vapor mixture flow as a second air-vapor mixture flow, to flow through a first heat exchanger and to flow through a second heat exchanger and a pressure reducing device that is configured to reduce the pressure of said second air-vapor mixture downstream said first heat exchanger. The selector is configured to direct most of the first air-vapor mixture to flow in a closed cycle through the container, or configured to exchange most of the first air-vapor mixture with air located outside the apparatus.

The present invention relates to a method of controlling a washing machine comprising an outer tub containing water, an inner tub which accommodates laundry and is rotatably installed in the outer tub, a dispenser which supplies detergent into the inner tub, and a spray nozzle for spraying water into the inner tub, including the steps of: (a) supplying water into the inner tub via the dispenser; (b) supplying water into the inner tub through the spray nozzle, during when water is supplied into the inner tub via the dispenser; and (c) rotating the inner tub at a cloth wetting speed at which at least some of the laundry in the inner tub is adhered to an inner surface of the inner tub and can be rotated integrally with the inner tub, during when water is supplied through the spray nozzle.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and is selectively rotated by a motor assembly. A controller is operably coupled to a water supply and the motor assembly and is configured to estimate a dry load weight of the load of clothes, determine a cloth type of the load of clothes, determine a remaining moisture content of the load of clothes based at least in part on the dry load weight and the cloth type, and transmit the remaining moisture content to a dryer appliance for improved operation.

A vent system for a dryer, may include an exhaust air conduit configured to provide an airstream to a dryer; a sensor within the conduit and configured to measure the airstream; and a controller configured to receive sensor data from the sensor and determine an airflow. A method for detecting a variation in airflow through a vent of a dryer may include receiving sensor data from at least one sensor in an air conduit of a clothes dryer; determining an estimated airflow based on the sensor data; comparing the estimated airflow to a predetermined expected airflow; and adjusting the estimated airflow in response to the estimated airflow not being within a predefined margin of the predetermined expected airflow.

A method of controlling load volume in a laundry drying appliance where a load of wet laundry is place in a drum of the laundry drying appliance and the load volume of the wet laundry is sensed or determined according to the method. A condition of the drum of the laundry drying appliance is actively monitored and a determination is made if a proper load volume is present in laundry drying appliance.

A method of operating a laundry appliance in a drying cycle includes motivating a flow of process air from a drum of the laundry appliance across an evaporator of a sealed system. Refrigerant in the evaporator of the sealed system absorbs heat from the flow of process air and the refrigerant circulates through the sealed system. The method also includes receiving, by a controller of the laundry appliance, an input indicative of a characteristic of the sealed system. The method further includes determining, by the controller, a dryness level of articles in the drum of the laundry appliance based on the received input indicative of the characteristic of the sealed system.

The present disclosure relates to a tumble dryer (1) with a filter arrangement (12) located in a tumble dryer process air flow (21) for removing lint from process air leaving tumble dryer drum. The filter arrangement comprises a first coarse-mesh filter (25) and a second fine filter (27). A first sensor (41) detects a correct positioning of the first filter in the tumble dryer, and a second sensor (33) detects a pressure drop over a process air flow path comprising the second filter. A control arrangement (45) is configured to initiate a disabling operation which disables the fan arrangement (12), if the first filter is not correctly positioned in the tumble dryer or if the pressure drop over the second filter exceeds a predetermined threshold value.
