Rotating tub body and drum-type washing machine having the same |
摘要 |
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. |
