A steam compressor may be provided to compress some of the air flowing through the air flow passage.

A method of operating a laundry treating appliance with a treating chamber for treating a load of laundry the method comprising supplying a rinse to the treating chamber during a rinse cycle, rotating the treating chamber at a tumbling speed, spinning the treating chamber in an extraction cycle to remove excess moisture from the load of laundry, sensing a parameter indicative of a remaining moisture content value in the load of laundry, comparing the remaining moisture content value to a pre-determined remaining moisture content value.

A wireless sensing device disposed a drum along with laundry to measure humidity in the drum, thereby increasing accuracy in estimation of a degree of dryness, a dryer for determining a degree of dryness of the laundry using the wireless sensing device, and a method of controlling the dryer. The wireless sensing device includes a sensing module including a humidity sensor for measuring humidity in a drum of a dryer into which the wireless sensing module is thrown; a sensor communication module transmitting or receiving data with a main communication module of the dryer through wireless communication; a sensor controller configured to control the sensor communication module to transmit a humidity value corresponding to an output of the sensing module to the main communication module; and a sensor power supplier supplying power to the sensing module, the sensor communication module, and the sensor controller.

A laundry treating appliance for treating laundry according to an automatic cycle of operation includes a cabinet defining a cabinet interior. A drum is rotatable within the cabinet interior, and at least partially defines a treating chamber. The treating chamber has a treating chamber air inlet and a treating chamber air outlet. A drying air circuit is fluidly coupled to the treating chamber air inlet and to the treating chamber air outlet. The laundry treating appliance can include first and second air temperature sensors, at least a first humidity sensor, and a controller operably coupled with the sensors.

A disclosed dryer includes a receptacle configured to contain material to be dried, an air duct configured to route recirculating air and/or fresh air to the receptacle, a heating device configured to heat the recirculating air, and at least one sensor. The sensor is configured to determine a relative humidity and/or temperature, and the air duct includes at least one adjusting element configured to modify a portion of recirculating air routed to the receptacle. The dryer further includes a control or regulating device configured to control or regulate the portion of recirculating air routed to the receptacle and/or a heating capacity of the heating device during a drying process. A disclosed method includes controlling a portion of recirculating air routed to the receptacle and/or a heating capacity of the heating device. Further, a mixture of recirculating air and fresh air are varied during heat-up, drying, and cool-down phases.

A method of operating a laundry treating appliance with a treating chamber for treating a load of laundry the method comprising supplying a rinse to the treating chamber during a rinse cycle, spinning the treating chamber in an extraction cycle to remove excess moisture from the load of laundry, sensing a parameter indicative of a remaining moisture content value in the load of laundry, comparing the remaining moisture content value to a pre-determined remaining moisture content value.

Among other things, a procedure is revealed which comprises the following: Detecting one or more pieces of air humidity information indicative of a relative humidity within a treatment room of an air-conducting domestic appliance, wherein the one or more pieces of air humidity information are detected by means of at least one air humidity sensor; and determining drying information indicative of a time of an end of a drying process performed by the air-conducting domestic appliance, wherein the drying information is determined based on the one or more pieces of air humidity information. Also disclosed are a device for executing and/or controlling this process, a system with one or more devices for executing and/or controlling this process and a computer program for executing and/or controlling this process by a processor.

Disclosed is a laundry treating apparatus including a cabinet, a drum, a fluid circulator, an air circulator including a humidity sensor, a driver, and a controller, wherein a drying operation includes an efficiency increasing process for increasing drying efficiency inside the drum, an efficiency maintaining process for maintaining the drying efficiency, and an efficiency decreasing process for reducing the drying efficiency, wherein the controller performs the drying operation while distinguishing the efficiency increasing process, the efficiency maintaining process, and the efficiency decreasing process from each other using a measured value of the humidity sensor.

A pump is configured to drain liquid from the wash basket. A vent line extends between the wash basket and the cabinet. The vent line includes a fan, a humidity sensor proximate the fan, and a controller. The controller is operable to perform a drain cycle. The drain cycle includes activating the pump. Comparing, across a set interval of time, a humidity within the washing machine appliance to a reference humidity. Determining the humidity's proximity to the reference humidity. Detecting a fault in the drain cycle in response to the humidity exceeding the reference humidity. Continuing a rinse cycle in response to the humidity being proximate the reference humidity.

A clothes dryer using an LED light source is proposed. Instead of using a heater, a blowing fan, and a heat exchanger, the clothes dryer employs a plurality of LED light source modules provided in a body and efficiently arranged therein and an air circulation structure of an air circulation part having a blowing fan arranged in the inner rear side thereof, and is configured to sterilize air through an air sterilization part, absorb and dry moisture by a ceramic filter, and then finally discharge the air to the outside through an exhaust fan. Therefore, without requiring a separate water discharge treatment process in an existing method, the clothes dryer can achieve efficient drying of clothes and drying of clothes without damage.
