Provided is a clothes dryer, and the clothes dryer includes a drum, an air supply and exhaust unit for supplying and discharging the air for drying to and from the drum, a burner for heating the air for drying, a temperature sensor for detecting the exhaust temperature, and a heating control unit for performing a temperature adjustment processing. The temperature adjustment processing enables the burner to stop when the exhaust temperature reaches an upper limit temperature and enables the burner to re-operate when the exhaust temperature is lowered to a specified re-ignition temperature. The heating control unit is provided with a re-ignition temperature adjustment part that performs an adjustment to lower the re-ignition temperature, and the re-ignition temperature is gradually lowered through the re-ignition temperature adjustment part every time when the temperature adjustment processing is repeated and intermittently to perform the re-ignition.

A clothes dryer may include a drum in which laundry is receivable; a humidity detector to detect a dryness level of the laundry in the drum; and a controller configured to: obtain the dryness level of the laundry in the drum detected by the humidity detector while a first initial drying cycle is performed, determine a weight category of the laundry in the drum from a plurality of weight categories of laundry based on the obtained dryness level, obtain control information based on the determined weight category, and control, according to the obtained control information, a main drying cycle to dry the laundry in the drum after the first initial drying cycle is performed.

A drying device is provided. The device includes a frame having a base portion with a plurality of supporting castor wheels. A front support and a rear support extend upwardly from opposing ends of the base portion. A horizontal bar is affixed between the upper ends of the front and rear supports. The horizontal bar may include various configurations of hooks and extending rods for hanging sports equipment and garments for storage and drying. The height of horizontal bar can be adjusted by a push button adjuster. A flexible transparent cover is removably securable around the frame. A forced air heater is disposed on the base portion of the frame. The forced air heater includes a temperature control, a timer control, and a tip-over switch. The device further includes an ozone generator with a timer control for deodorizing the contents of the bag during the drying process.

A washer comprising: a first heater to heat washing water; a second heater to heat air; a fan to guide air; a memory to store one or more programs; and a controller which is electrically connectable to the first heater, the second heater, the blower fan, and the memory. The washer is controlled by the controller to sequentially perform a washing cycle, a first rinsing cycle, a second rinsing cycle, a spin-drying cycle, and a drying cycle, wherein the second rinsing cycle includes an operation of heating the washing water through the first heater and an operation of rotating the drum, and the spin-drying cycle may include heating the air through the second heater in at least a part of a section based on a rotation speed of the drum, and guiding the heated air into the drum by using the blower fan.

Disclosed is a clothes dryer. The clothes dryer includes a drum; an air supply/exhaust unit for supplying/exhausting drying air to/from the drum; a burner for heating the drying air; a temperature sensor for detecting an exhaust temperature; and a heating control unit for performing a temperature adjustment process of stopping the burner when the exhaust temperature reaches an upper limit temperature and restarting the burner after a time point when the exhaust temperature decreases to a re-ignition temperature. The heating control unit has a delay time inserting portion, which inserts a delay time between the time when the exhaust temperature decreases to a lower limit temperature and the time when the burner is restarted. The delay time is increased every time the temperature adjustment process is repeated intermittently.

A laundry appliance including an appliance housing, a tub positioned inside the appliance housing, a drum rotatably supported within the tub, and a drying system that recirculates drying air through a molecular sieve. The molecular sieve has a porous membrane that is arranged along a drying air recirculation path. The laundry appliance also includes an ejector with an inlet, a venturi nozzle, an outlet, and a suction port that is arranged in fluid communication with the molecular sieve. The suction port of the ejector is configured to pull water vapor in the drying air recirculation path through the porous membrane of the molecular sieve when a motive fluid is passed through the ejector from the inlet, through the venturi nozzle, to the outlet such that the drying air exiting the molecular sieve is less humid than the drying air entering the molecular sieve.

A laundry treatment apparatus includes a cabinet defining an appearance thereof, a tub disposed in the cabinet, a drum rotatably disposed in the tub, and an air supply unit configured to heat and circulate air in the tub, the air supply unit including a fan duct coupled to an air collection port provided at the tub so as to collect the air in the tub, a heating duct fixed to an upper portion of the tub and coupled to the fan duct so as to heat air supplied from the fan duct and to guide the air in a forward direction of the tub, and a supply duct coupled to the heating duct so as to supply air in a forward direction of the tub.

A clothes care apparatus according to a disclosed embodiment includes: a chamber; an upper fan provided on an upper side of the chamber and configured to move air in a lower side direction of the chamber; a lower fan provided on a lower side of the chamber and configured to move air in an upper side direction of the chamber; a first motor configured to rotate the lower fan; a steam generating device configured to generate steam by heating water; and a controller configured to control on/off of the steam generating device and the first motor and turn on the steam generating device in a first section for supplying the generated steam into the chamber and turn on the first motor in a second section for dispersing the steam by the air moving into the chamber.

A laundry machine (100) is disclosed. The laundry machine (100) includes a tub (120), an air supply unit (160) configured to circulate air in the tub (120), a heat pump including a compressor (165), an evaporator (220), an expansion valve, and a condenser (240), the heat pump being configured to dehumidify and heat the air from the air supply unit (160), and a cooling unit (300, 400, 500) installed at the compressor (165) to cool the compressor (165) using a supplied fluid.

A gas-fired heating device and a gas-fired clothes dryer, where the gas-fired clothes dryer includes the gas-fired heating device, and the gas-fired heating device includes a burner and an igniter, where the burner includes a body and a gas collecting plate, the gas collecting plate is concave upwards to form a gas collecting chamber, and the body has a combustion end provided with a nozzle; the gas collecting plate is connected with the combustion end, and the gas collecting plate is located above the nozzle, so that gas ejected from the nozzle enters the gas collecting chamber; the igniter is provided with an ignition end located outside the nozzle, and the ignition end extends into the gas collecting chamber.
