Cleaning assembly, self-cleaning method for cleaning assembly, and electrical device

Abstract

The present invention relates to a cleaning assembly, a self-cleaning method for the cleaning assembly, and an electrical device. The cleaning assembly includes a drum; a scraping plate, abutting a cylindrical surface of the drum on a side; a drum cover, connected to the scraping plate and surrounding the drum; a liquid collection chamber, where a part of the cylindrical surface, the scraping plate, and the drum cover enclose the liquid collection chamber; a liquid supply channel, communicating with the liquid collection chamber and configured for pouring a cleaning liquid into the liquid collection chamber or onto a surface of the drum; and a liquid discharge mechanism, communicating with the liquid collection chamber and configured to allow the liquid in the liquid collection chamber to be discharged. The cleaning assembly is configured to: close the liquid discharge mechanism during a drum self-cleaning operation, such that the cleaning liquid accumulates in the liquid collection chamber without being discharged; and use the accumulated cleaning liquid to clean the drum when the drum is driven to rotate towards the scraping plate. In this manner, the electrical device does not need to return to a base station, improving the cleaning effect of the drum and saving time.
