A clothes dryer having a preheating unit preheating drawn air is provided. The clothes dryer includes a main body, a drying tub rotatably mounted to receive an object to be dried, and a hot air duct supplying hot air into the drying tub. The hot air duct includes a heating unit heating drawn air, and a hot air supply unit connecting the heating unit with the drying tub, thereby forming a path for heated air. The heating unit includes a first heating unit having a heater part generating heat, and a second heating unit surrounding an entrance and outer walls of the first heating unit, thereby forming a path for the air flowing to the first heating unit. The second heating unit includes one or more preheating fins formed on the first heating unit to contact the air flowing in the second heating unit.

A dryer and a control method thereof, in which load of an object to be dried is detected using a sensor which has less risk of contamination and an anticipated drying time based on the detected load is accurately determined and displayed. The dryer includes a rotatable drum to accommodate the object, a front support installed at an entrance of the drum to support the drum, a rear support installed at an opposite side of the entrance of the drum to support the drum, an exhaust hole formed in the front support, through which interior air of the drum is discharged, and a humidity sensor installed to the front support at a position adjacent to the exhaust hole, the humidity sensor being located upstream of the exhaust hole in a rotating direction of the drum to detect humidity of the air to be introduced into the exhaust hole.

A clothing dryer and a control method thereof that adjusts a heater capacity based on a humidity change amount (a drying rate) in a second half of a drying period to reduce power consumption without increase of drying time. The clothing dryer includes a drum to receive clothing, first and second hot air heaters, having different capacities, to supply hot air into the drum, a humidity sensor to sense internal humidity of the drum, and a controller to calculate a humidity change amount in the drum, to compare the calculated humidity change amount with a predetermined change amount, and to control only one having the relatively small capacity selected from the first and second hot air heaters to be operated when the humidity change amount is greater than the predetermined change amount.

Disclosed is a stepped embroidery machine. The stepped embroidery machine includes a plurality of head units including heads, embroidery frames installed at lower portions of the heads is such a manner that the embroidery frames are movable in X-axis and Y-axis directions, X-axis drive units for moving the embroidery frames in an X-axis direction, and Y-axis drive units for moving the embroidery frames in a Y-axis direction, a control unit for controlling an operation of the head units, and a control panel used for inputting and displaying information related to embroidery work and embroidery. The head units are individually driven per each head unit and aligned in a stepped pattern while forming a predetermined step difference therebetween. Since the head units are individually driven, it is possible to individually perform embroidery work with respect to various workpieces. The head units are aligned in the stepped pattern while forming a predetermined step difference therebetween, so the head units do not interfere with each other even if the embroidery machine performs the embroidery work with respect to workpieces having a large area. The head units are controlled with one control unit and one control panel, so the worker simultaneously controls the head units of the embroidery machine without changing positions of the worker, facilitating the embroidery work.
摘要:
An encapsulated nanostructure fabricated using layers of polymer material and further processed for use in a micro-scale target device is presented. The fabrication includes the formation on a substrate of an array of encapsulated nanostructures. The encapsulated nanostructures each include a nanostructure and a micro-scale, multi-block structure that encapsulates the nanostructure. Each encapsulated nanostructure can be made usable by a target device by removing, e.g., by etching, one of the layers to expose a portion of the nanostructure.

Disclosed are a washing machine having a drying device, which performs a spin-drying operation at a maximally low RPM and supplies cold air to clothes in a delicate course so as to minimize damage to the clothes and improve rinsing and spin-drying efficiencies, and a method for controlling spin-drying of the washing machine. The method for controlling spin-drying of the washing machine, which has a rotary drum for containing clothes, a motor for rotating the rotary drum, and a fan for circulating air into the rotary drum, includes determining whether or not a delicate course is selected; performing low-speed spin-drying in which the rotary drum is rotated at a low speed by operating the motor at a low RPM, when it is determined that the delicate course is selected; and supplying cold air to the inside of the rotary drum by operating the fan together with the low-speed spin-drying.
