Washing assembly and washing device

Abstract

A washing assembly comprises a large tub, a small tub and a first impeller, wherein the first impeller is located inside the large tub and at the bottom of the large tub, and the small tub is located inside the large tub. The small tub is arranged on the first impeller. A drainage channel is arranged on the side wall of the small tub in the length direction of the small tub, and a water inlet of the drainage channel is located at the top of the wall of the small tub. The bottom of the first impeller is provided with a drainage hole, the drainage channel being in communication with the drainage hole. When the small tub rotates, water in the small tub flows into the drainage channel, and is then discharged to the bottom of the first impeller through the drainage hole.
