Disclosed herein is a method of controlling a laundry dryer for generating high-temperature steam through a steam part and controlling each of rotation of a drum and rotation of a circulation fan. The method includes a steam drying procedure drying operation of increasing an internal temperature of the drum to dry an object to be dried, a steam drying procedure steam supply operation of supplying steam into the drum after the steam drying procedure drying operation, and a re-drying operation of supplying hot air into the drum after the steam drying procedure steam supply operation. When steam is sprayed from the steam part, the rotation of the drum is maintained, the rotation of the circulation fan is stopped, such that the steam is evenly supplied to the object to be dried, damage to the object is prevented, and sterilization of the object is enhanced.

A drying machine may include a drum configured to accommodate clothes, a fan motor configured to generate a flow of air, a heater configured to heat the air, a modulator configured to adjust a quantity of heat provided by the heater, and a user interface configured to provide a manager menu to correct a difference between a current quantity of heat caused by adjustment of the modulator and a target quantity of heat generated by variation in the modulator, where the modulator may include a device configured to manually set a maximum pressure and a minimum pressure.

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 includes a tub that is positioned within a cabinet. A drum includes an imperforate outer wall that is rotationally positioned within the tub. A blower delivers process air through an airflow path that includes a processing space defined within the drum. A heat exchange system conditions the process air that is delivered at least into the processing space as heated process air for drying articles contained within the processing space. The imperforate outer wall of the drum and the tub define supplemental heat exchange space that delivers supplemental heat through the imperforate outer wall and into the processing space. The supplemental heat exchange space is in thermal communication with the heat exchange system.

The present invention relates to an online system and a control method therefor, the online system comprising a clothing apparatus which may determine a cycle or an option by calculating the contamination level and wrinkling of clothes, or intensively treat parts that are contaminated or wrinkled, or recommend laundering with a washing machine when the contamination level or wrinkling is equal to or greater than a reference value, or induce a server or a washing machine to determine an appropriate cycle or option for laundering the clothes.

A clothes dryer capable of minimizing heat energy loss and increasing energy efficiency includes a cabinet, a drum provided within the cabinet, an exhaust duct through which air discharged from the drum is discharged out of the cabinet, an intake duct through which air is guided to the drum, a heating portion which heats air introduced into the intake duct, a heat exchanger provided within the exhaust duct and having a first heat exchange space in which air discharged from the drum exchanges heat with air introduced from the inside or outside of the cabinet into the exhaust duct, and a preheating member including a second heat exchange space through which air passing through the heat exchanger is guided to the intake duct so that air flowing into the intake duct via the heat exchanger exchanges heat with heat radiated from the intake duct in the second heat exchange space.

A mounting system for a laser detection sensor in a ductwork for the detection of unburnt fuel is provided. The mounting system includes a laser transmitter mount configured to provide adjustment of a laser transmitter and a laser receiver mount configured to provide adjustment of a laser receiver. The mounting system also includes a laser path extending between the laser transmitter and the laser receiver that includes an entrance port in the ductwork and an exit port in the ductwork. The mounting system also includes a flexible joint in the mounting system, where the flexible joint is configured to isolate at least one of the laser transmitter and the laser receiver from movement of the ductwork.

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.

The present invention relates to an online system and a control method therefor, the online system comprising clothing devices which may receive physical information of a user, notify of a change in the physical information, register clothing information held by the user, put together the schedule of the user, weather, preferences, the trend in the area where the user is located, and information on the clothing being sold, and recommend customized clothing to the user.
