Abstract

The present invention relates to an attached block structure for an inner barrel of a washing machine. The attached block structure is of a thin wall structure, which is installed on an inner wall of the inner barrel of the washing machine, a series of bulge structures (1) are arranged on one side of the thin wall structure facing interior of the inner barrel of the washing machine, and the bulge structures (1) are distributed along curves. The attached block structure for the inner barrel of the washing machine increases the rolling strength of washing water; and meanwhile, the bulge structures (1) additionally arranged on the attached block structure can not only realize a better rubbing and kneading effect on clothes, but also realize a certain three-dimensional water flow effect, thereby improving the washing cleanness, and having better user experience.

Claims

1. An attached block structure for an inner barrel of a washing machine, comprising:

a thin wall structure, which is installed on an inner wall of the inner barrel of the washing machine;

a series of bulge structures are arranged on one side of the thin wall structure facing interior of the inner barrel of the washing machine, and the bulge structures are distributed along curves.

2. The attached block structure for the inner barrel of the washing machine according to claim 1, wherein an upper part of the thin wall structure is installed near a top of the inner barrel, and a lower part of the thin wall structure is installed near a junction between a bottom of the inner barrel and a drum body.

3. The attached block structure for the inner barrel of the washing machine according to claim 2, wherein the thin wall structure is in a rectangular shape as a whole, a width is ⅕

-⅔
