VACUUM CLEANER WITH CYCLONE-TYPE DUST COLLECTOR Russian patent published in 2004 - IPC

FIELD: mechanical engineering, in particular, vacuum cleaning equipment.

SUBSTANCE: vacuum cleaner has suction brush movable over surface to be cleaned and equipped with drive engine chamber incorporating vacuum engine. Vacuum cleaner housing is detachably attached to suction brush at predetermined angle and provided with air discharge channel communicated with suction brush and drive engine chamber. One side of cyclone casing is arranged in vacuum cleaner housing. Cyclone casing has outlet air duct connected to inlet air duct designed for communication with suction brush and air discharge channel for creating of cyclone flow in air flow delivered through air inlet duct and containing dust and contaminants. Contaminant collector detachably mounted at lower end of cyclone casing is adapted for collecting of dust and contaminants separated by centrifugal force created by cyclone flow in cyclone casing. Grid unit is positioned at leading end of outlet air duct in cyclone casing for preventing dust and contaminants from flowing back through outlet air duct. Ultraviolet lamp is arranged in the vicinity of contaminants collector of vacuum cleaner housing in slot made flush with one side of contaminants collector. Ultraviolet lamp is adapted for emitting of ultraviolet beams, when contaminants collector is connected to vacuum cleaner housing. At forward side of cyclone casing and contaminants collector, when side of cyclone casing arranged in vacuum cleaner housing is viewed as rear side, protrusion of through flow part is formed for unobstructed collection of large-sized particles of contaminants separated by centrifugal force created by cyclone flow in cyclone casing.

EFFECT: reduced amount of contaminants and dust apt to change direction of motion in protruding portion of through flow part owing to widened space between contaminants collected in the vicinity of protruding portion of through part and cyclone casing.
