A washing machine has cleaning particles provided between an outer barrel and an inner barrel. A water outlet on the outer barrel communicates with a drainage device including a drain valve body having a particle receiving and discharging chamber and a drainage chamber. The particle collecting and discharging chamber has a water inlet. The drainage chamber has a water outlet. A particle filtering structure is provided between the particle receiving and discharging chamber and the drainage chamber. One side of the particle collecting and discharging chamber has an opening with a sealing cover including an outer cover and an insertion portion inserted through the opening, and fitting the edge wall of the particle receiving and discharging chamber. An inner wall of the insertion portion has a plurality of protrusions for supporting the cleaning particles. Gaps between the protrusions are smaller than a minimum diameter of the cleaning particles.

Drainage device of washing machine, and washing machine

A thread debris filtering apparatus includes a thread debris filter, where the thread debris filter includes a filter front cover () and a filter rear cover () connected with the filter front cover; a water filtering part () is arranged on the filter front cover (); a water inlet () is arranged in the filter rear cover (); backflow prevention structures () are arranged on an inner wall of the filter rear cover (); and the backflow prevention structures () are arranged at the lower part of the water inlet () and close to the water inlet ().

Thread debris filtering apparatus

The present disclosure discloses a freely rotating wave wheel having a housing cavity. The freely rotating wave wheel includes an impeller; an impeller rotating shaft is connected to the impeller; a freely rotatable impeller rotating wheel is installed on the impeller rotating shaft; and a housing cavity is arranged inside the impeller rotating wheel, and/or between the impeller rotating wheel and the impeller, and/or between the impeller rotating shaft and the impeller. Antibacterial and disinfectant substances or other substances beneficial to washing effects of clothes can be arranged in the housing cavity. When water enters into the washing machine to wash and rinse clothes, antibacterial and disinfectant substances or other substances beneficial to washing effects of clothes can effectively perform effects to purify water quality and prevent cross infection due to mixed washing of clothes, thereby generating a better washing effect.

Freely rotating wave wheel having housing cavities

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 () 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. The attached block structure for the inner barrel of the washing machine increases the rolling strength of washing water; and meanwhile, the bulge structures () 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.
