Abstract: A washing and drying machine that is capable of performing heat exchange between outside air introduced into a cabinet and the circumferential surface of a tub so as to condense air used to dry laundry. No cooling water is used to condense air used to dry the laundry. Consumption of water is reduced, and therefore, the maintenance costs of the washing and drying machine are decreased. Furthermore, no condensing duct is necessary. Consequently, flow resistance is decreased, and drying efficiency is improved. In addition, sufficient space is provided between the rear surface of the tub and the cabinet. Consequently, the volume of the drum is increased, and the washing/drying capacity of the washing and drying machine is increased.

An exemplary embodiment of our inventive active coating system is corrosion resistant and includes a flexible sensor layer, a switch layer and a visual display layer. Operationally, the flexible sensor layer senses particular environmental conditions and the visual display layer provides visual indication of the condition(s) sensed.

Abstract: A washing-drying/drying machine includes a tub mounted in a cabinet; a drum rotatably disposed in the tub for receiving laundry; a cooling water supply unit for supplying cooling water to condense moisture in air discharged from the drum; and a condensing plate mounted between the drum and an inner wall of the tub for receiving the cooling water to condense the moisture in the air.

Abstract: A drum type washing machine includes a cabinet, a tub fixed in the cabinet, and a drum that performs a washing process. A motor rotates the drum, a supporting device that extends from a rotation shaft of the motor to the cabinet rotatably support the drum. A buffering-and-sealing device is provided at the rear side of the tub to buffer a space between the rotation shaft and the tub and to seal the rear side of the tub. A drying device extends from one side of the tub to the other side of the tub to circulate air in the drum and to dry laundry in the drum. Thus, the size of the washing machine is reduced, the washing capacity thereof is increased, and laundry is dried by the drying device.

Abstract: A drum washing machine includes a cabinet forming an external housing of the washing machine, and a tub is installed in the cabinet for containing washing water. A drum is rotatably installed in the tub. A circulation pump pumps the washing water in the tub and resupplies the washing water to the inside of the drum and at least one circulation hose provides a circulation path between the circulation pump and the tub.

Abstract: Disclosed herein is a washing machine. The washing machine comprises at least one damper disposed between a drive part of the washing machine and a cabinet for performing shock-absorbing operation, a damper bracket fixedly attached to the drive part for transmitting vibration or impact to the at least one damper, and a revolute joint connection unit connected between the at least one damper and the damper bracket. When non-horizontal vibration or impact is transmitted to the at least one damper, the damper is rotated by the revolute joint connection unit. Consequently, the shock-absorbing operation is effectively performed.

Abstract: Disclosed herein is a balancer of a washing machine. The balancer comprises a balancer ring mounted to a drum, the balancer ring having a liquid receiving space for receiving liquid, a plurality of first baffles disposed in the interior of the balancer ring, and a plurality of second baffles disposed between the first baffles such that the first and second baffles are alternately arranged, the second baffles having a height lower than that of the first baffles. When abnormal vibration is generated in the washing machine, the surge of salt water is effectively prevented by the second baffles. Consequently, further noise and vibration due to a resonance phenomenon or other abnormal vibration is minimized.

Abstract: A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume.

Abstract: Disclosed herein is a drum type washing machine. The drum type washing machine comprises front and rear balancers mounted at the front and rear sides of a drum, respectively. Consequently, an eccentric force generated by laundry is complementarily eliminated by the front and rear balancers even when the laundry is eccentrically placed at one side of the drum.
