  • Patent number: 8621896
    Abstract: A drum type washing machine is provided. The washing machine includes a tub, a drum rotatably installed in the tub, and a shaft that penetrates the tub and is connected to the drum so as to transmit a drive force of a motor to the drum. A stator is fixed to a rear wall of the tub, and an outer rotor, including at least one magnet, an annular back yoke, and a rotor frame, is rotatably disposed at the outside of the stator. The rotor frame may be made of an aluminum material, and includes a side wall portion and a rear wall portion integrally formed with the side wall portion.

  • Patent number: 8616027
    Abstract: Disclosed is a drum type washing machine with a cabinet for forming an appearance; a tub fixed to an inner side of the cabinet and for storing washing water, a drum rotatably arranged in the tub for washing and dehydrating laundry, and a driving motor positioned at a rear side of the drum for generating a driving force by which the drum is rotated. The washing machine can increase washing capacity with maintaining an entire size thereof by increasing a diameter of the drum without increasing a size of the cabinet. The washing machine may include a supporting plate to rotatably support the rotational shaft, and a supporting unit to support the supporting plate, the supporting unit comprising a plurality of supporters connected between the supporting plate and the cabinet.

  • Patent number: 8528231
    Abstract: A dryer is provided. The dryer may include a main body having an inner space formed therein, a support body arranged in the main body so as to form a frame of the main body, a flexible drum rotatably installed on the support body so as to have a non-circular cross-section as it is rotated, and rotation guides arranged between the support body and the flexible drum so as to guide rotation of the flexible drum. A distance from a center of rotation of an inscribed circle contacting the inner circumferential surface of the flexible drum to one random point on the inner circumferential surface of the flexible drum is greater than a distance from the center of rotation of the inscribed circle to another point on the inscribed circle such that the drum maintains a non-circular cross section.

  • Patent number: 8499473
    Abstract: An upper cabinet of a rotary-drum laundry dryer outer casing can include a rear wall. The rear wall can include a sink-shaped bulge or recess. The bulge or recess can project outwards of the upper cabinet, be roughly centered to a rear rim of a dryer drum, and include a through opening. The upper cabinet can also include a substantially circular, basin-shaped lid or cover fixed to the inner face of the cabinet rear wall substantially coaxial to the drum. The lid or cover can be shaped so as to completely cover and close the outwards-projecting bulge or recess on the cabinet rear wall. This can form, on that rear wall, a cavity which communicates with the inside of drum and also with a hot-air generator via the through opening.

  • Patent number: 8490439
    Abstract: In a laundry washer, relatively short bursts of operation of a recirculation pump are coordinated with corresponding brief intervals of tub rotation during the initial fill periods. The aim is to thoroughly wet the clothes early in each wash/rinse phase to thus improve the wash/rinse effectiveness, while also avoiding excessive suds formation. Following the initial fill periods and during regular wash/rinse agitations, the recirculation system may also be employed to “recharge” the laundry load with detergent that has settled in the bottom of the tub. In a further aspect of the invention, some or all of the conventional intermediate spin extractions are omitted. In this manner, more water is carried over in the clothes from one wash/rinse cycle to the next. An intermediate spin of reduced speed (RPM) and duration as compared to typical normal intermediate spins may be employed between the wash phase and first rinse.

  • Patent number: 8464561
    Abstract: A front-loading drum-type washing machine with a housing having a front wall and a housing wall opening disposed in the front wall. A suds container is disposed in the housing, the suds container having a suds container opening. A drum is rotatably mounted in the suds container. the drum has a drum opening with an edge. A bellows seal is disposed between the suds container and the housing wall opening. A laundry deflector is disposed in an upper area of the suds container opening, the laundry deflector being directed toward the drum and extending over the drum opening edge so as to form a gap with the drum opening edge. The laundry deflector is configured such that the extent to which it extends and a corresponding dimension of the gap is variable. The variable gap dimension is controllable and adjustable as a function of a speed of the drum.

  • Patent number: 8434334
    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.
