FIELD: built-in cleaning equipment used in home rooms. ^ SUBSTANCE: vacuum cleaner has dust collecting section connected with section of double cyclone having inner part formed as cylinder, upper part with tangential inlet for dust-and-air mass, and lower part with dust separator formed as truncated cone. Apex of truncated cone is oriented toward dust collector. Truncated cone is provided on its inner conical surface with ribs oriented toward its apex. Draft inducer mounted within opening of cover of cyclone double section is provided with electric engine and air turbine axially aligned with electric engine and having tangential air flow outlet. Area of section of inner part of double cyclone does not exceed area of section of its outer part. Rib profile defines quasi-involute. Vacuum cleaner of such construction is of stationary type and is equipped with stationary inlet and outlet pipelines. ^ EFFECT: increased power and improved cleaning efficiency. ^ 2 cl, 3 dwg |
