Freely rotating wave wheel having housing cavities
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.
