VACUUM CLEANER Russian patent published in 2010 - IPC A47L9/10 A47L9/20 

FIELD: private use articles.

SUBSTANCE: invention refers to vacuum cleaner consisting of section of dust separation for separating dust and air sucked by means of electric fan, of section for dust collection after separation of dust from air in dust separation section, of filtering section rotating in case of container which is installed after dust separation section and designed to separate fine dust passed through section of separating dust from air and of rotation drive of filtering section. In the case of the container there is made an aperture for input of external air into the case of the container. The vacuum cleaner is equipped with a component for opening/closing an aperture for external air input, with a communicating channel designed for connection of the section of dust separation and the case of the container and the component for opening/closing the air communicating channel. The vacuum cleaner has a module of control over air flow which at common cleaning creates the first path of air flow and lets it through the section of dust separation via the channel communicating the section of dust separation with the case of the container and via the filtering section for suction of this flow with the electric fan. Also at air cleaning there is created the second channel for passing the flow sucked with the electric fan through the filtering section of the compartment without supply of air from the aperture for input of external air. The vacuum cleaner is equipped with a mechanism of interlock of component of opening or closing external air and component of opening or closing the channel communicating the section of dust separation with the case of the container depending on the direction of filtering section rotation actuated by the drive. When filtering section rotates in one direction there is created the said first channel by opening the channel communicating the section of dust separation with the case of the container by means of the opening/closing component, and closing the aperture for external air input with the opening/closing component. When the filtering section rotates in another direction there is created the said second channel communicating the section of dust separation with the case container by means of closing the channel with the opening/closing component and opening the aperture for external air input.

EFFECT: preventing dropped dust sticking to filtering section.
