| 20110048080 | DRUM FOR A LAUNDRY TREATMENT MACHINE - A drum for a laundry treatment machine that is rotatably mounted within the housing of the laundry treatement machine, and wherein the drum includes a bottom disk and a jacket which are individually or jointly provided with a curved structure. The curved structure includes at least two rows of prism-type embossings that have substantially rectangular base, and the at least two rows encompass at least partially the drum. A surface of embossings that is directed in a circumferential direction of the drum is arranged at a steep angle to the jacket; an opposing surface of the embossings is arranged at a flat angle to the jacket; and lateral surfaces of the embossings are arranged at least nearly at a right angle to the jacket. | 03-03-2011 |
| 20120222455 | Washing Machine Wherein the Unbalanced Load is Balanced - The present invention relates to a washing machine ( | 09-06-2012 |
| 20120304705 | ROTATING TUB BODY AND DRUM-TYPE WASHING MACHINE HAVING THE SAME - A cylindrical rotating tub body and a drum-type washing machine having the same, in which the rotating tub body is formed by rolling a plate such that both ends of the plate are connected to each other. The washing machine includes a cylindrical rotating tub body and a plurality of lifters, which are spaced apart from each other on an inner peripheral surface of the rotating tub body. The rotating tub body includes lifter installation sections on which a plurality of lifters are installed, concave-convex sections having a plurality of concave-convex parts and being installed between the lifter installation sections, and reinforcement sections to reinforce the strength of the lifter installation sections. The lifter installation sections having a strength lower than that of the concave-convex sections are reinforced due to the reinforcement sections, so that the lifter installation sections are prevented from being extremely being deformed during the rolling process. | 12-06-2012 |
