A laundry treating apparatus may include a drum in which laundry is stored, an air flow passage through which air is circulated, and a heating duct configured to supply hot air to the drum. The air flow passage and heating duct may be configured to prevent or reduce or cooling or condensing of moisture in the circulated air. A steam compressor may be provided to compress some of the air flowing through the air flow passage.

A clothes treatment apparatus includes: a cabinet forming a treatment space for storing clothes; a filter module having a filter portion for filtering out dust from air passing therethrough; an air flow path having a plurality of preset flow paths for directing air to be discharged into the treatment space; a fan for moving the air in the air flow path; at least one valve disposed on the air flow path; a valve actuating module for actuating the valve; and a control part for controlling the valve actuating module so as to select one of the plurality of flow paths. The plurality of flow paths include: at least one bypass flow path for directing the air to bypass the filter portion; and at least one filtering flow path for directing the air to pass through the filter portion.

A dryer appliance, a controller, and a method for operation are provided. The controller is configured to execute steps of a method including receiving an input indicative of a drying cycle end time; determining a moisture extraction rate based at least in part on the received input indicative of drying cycle end time, the moisture extraction rate indicative of a rate at which moisture is removed from articles within a chamber of the dryer appliance; determining a rate of change of moisture extraction rate corresponding to the drying cycle end time; and adjusting a condensation rate based at least on the rate of change of moisture extraction rate and the received input indicative of the drying cycle end time.

The present disclosure relates to an integrated laundry treatment apparatus, in which a washing machine module and a drying machine module are integrally installed in a common cabinet, and a single drying module is provided to produce dry hot air, such that a size of a product may be reduced, a dried state of laundry being dried in a washing drum and a drying drum is detected in real time while drying processes are simultaneously performed in the washing drum and the drying drum by the common drying module, and the amount of supplied dry hot air and the amount of recovered dry hot air are differently controlled, such that an overall drying process time may be reduced and electric power consumption may be minimized, and the drying processes performed in the drying process and the drying machine of the washing machine are simultaneously completed, such that convenience for a user may be improved, and a method of controlling the same.

A clothes care apparatus includes a chamber, an upper fan provided above the chamber and configured to move air to a lower side of the chamber, and a lower fan provided under the chamber and configured to move air to an upper side of the chamber. A first motor is configured to rotate the lower fan and a steam generating device is configured to generate steam by heating water. A controller is configured to control on-off states of the steam generating device and the first motor, configured to turn on the steam generating device in a first period for supplying the generated steam to the chamber, and configured to turn on the first motor in a second period for allowing the steam to be dispersed by air moving to the chamber.

A laundry appliance includes a drum that is rotatably mounted within a cabinet and defines a chamber for receiving articles of clothing. Primary and ambient air duct systems provide fluid communication between a conditioning system and at least one of the chamber of the drum and an ambient environment, respectively. A blower fan urges air through the conditioning system and a damper system is operably coupled to the ambient air duct system for selectively regulating a flow of ambient air. A controller is configured to receive a command to initiate a dehumidification cycle, operate the conditioning system and the blower, and regulate the damper system to permit the flow of ambient air to pass through conditioning system and through the ambient air duct system, thereby dehumidifying the ambient environment.

A clothes care apparatus includes a chamber, a first damper, a second damper, a heat exchanger, at least one blower fan, a sensor portion, and a controller. The first damper is configured to control an airflow from inside the chamber to outside the chamber. The second damper is configured to control the airflow into the chamber from the outside. The heat exchanger is provided with a compressor and configured to exchange heat with air in the chamber. The at least one blower fan is configured to generate the airflow. The sensor portion is configured to obtain a temperature and humidity inside and outside of the chamber. The controller is configured to start a drying cycle, control the first and second damper to be opened or closed, and control the heat exchanger and the at least one blower fan by comparing the internal humidity with the external humidity.

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.

Disclosed is a dryer operating method that is useful in a 5G environment provided for the Internet of Things. The dryer of the disclosure includes a heating device, a tumbler connected to the exit of the heating device, a fan connected to the exit of the tumbler, a heat exchanger disposed in a flow line of a working fluid connected to the exit of the fan, and a compressor having an entrance connected to the flow line connected to the exit of the fan and an exit connected to the entrance of the heat exchanger. The method of the disclosure includes heating the working fluid using the heating device, reducing the pressure in the tumbler by discharging a portion of the working fluid in a circulation line to outside using the compressor, drying an object to be dried received in the tumbler, and cooling the object to be dried.
