FIELD: air cleaning equipment. SUBSTANCE: proposed multi-cyclone dust accumulator includes housing of primary cyclone and dust collecting reservoir for circulation of air and accumulation of various foreign matter; housing of primary cyclone and dust collecting reservoir have first air inlet passage for suction of air together with foreign particles and first air outlet passage for escaping of air after primary removal of foreign particles; housing of secondary cyclone is located above housing of primary cyclone and dust collecting reservoir for circulation of air in direction perpendicular to flow of air in housing of primary cyclone and dust collecting reservoir; housing of secondary cyclone has second air inlet passage which is communicated with first air outlet passage for suction of air from housing of primary cyclone and dust collecting reservoir to housing of secondary cyclone in direction tangential relative to inner circumference of housing of secondary cyclone and second air outlet passage located in center of one side of housing of secondary cyclone near first air outlet passage which has part projecting inside housing of secondary cyclone communicated with space where fan is located and second dust collecting reservoir provided with port on other side relative to second air inlet port. EFFECT: enhanced efficiency of removal of particles excluding unpleasant odor. 13 cl, 13 dwg
