VACUUM CLEANER FOR WET AND DRY CLEANING Russian patent published in 2005 - IPC

FIELD: vacuum cleaner for wet and dry sweeping of surface and for filtering of dry media, such as dust, and wet media, such as water.

SUBSTANCE: vacuum cleaner has vacuum creating device, casing with base equipped with receptacle part arranged on its one side, said vacuum creating device being mounted on said side. Inner receptacle standing on base in vertical position has discharge cavity for eliminating interference with said device, space for accommodation of contaminants separating device, inlet opening connected with head movable over surface under cleaning process, and outlet opening in upper part of said space, said outlet opening being adapted for exit of purified air and being formed in discharge cavity. Outer receptacle is mounted on base in vertical position so as to surround inner receptacle, and has first and second through openings corresponding to inlet and outlet openings of inner receptacle, said outer receptacle providing for communication between contaminants separating device and outlet opening, and discharge channel for discharge of air separated in contaminants separating device to the outside through discharge opening of vacuum cleaner casing. Contaminants separating device is detachably positioned in casing and is designed for separating of air, saturated with contaminants and moisture and drawn through inlet opening, into air component and accumulated component consisting of contaminants and water and separated from air component. Casing top opening is hermetically closed with cover. According to another version, vacuum cleaner has through-flow electric engine mounted into receptacle part and adapted for creating vacuum. Inner receptacle mounted on base has discharge cavity for eliminating interference with electric engine.
