Abstract

An electric vacuum cleaner, comprising: a dust collection container (22), which is formed into a bottomed cylindrical shape with an open surface (22b) on one end surface, and has an airflow inlet (22a) on the peripheral surface; The filter (37), which is arranged on the opening surface (22b); the dust removal part (33), which beats the filter (37) to remove dust; the supporting surface (50b), which is arranged under the filter (37), is vertically It is formed on an axial plane, and receives the dust falling off from the filter (37) due to the dust removal part (33); the inner cylinder (51), which opens on the support surface (50b) and extends downward, and is connected with the dust collection container (22) Coaxial arrangement, with an outlet (51a) for the airflow flowing out from the dust collection container (22) on the peripheral surface; and a flexible sliding part (53), which rotates and slides on the supporting surface (50b) , forming a vortex that guides the dust to the inner cylinder (51).

Description

technical field [0001] The present invention relates to an electric vacuum cleaner equipped with a dust removal device of a filter. Background technique [0002] Patent Document 1 discloses a conventional electric vacuum cleaner. This electric vacuum cleaner includes a main body in which an electric blower is incorporated. A cyclone-type dust collection unit is disposed in the main body and in front of the electric blower. The dust collection part is equipped with the bottomed cylindrical dust collection container which has a circular cross section and has an opening surface on the upper surface. An inflow port is provided on the peripheral surface of the dust collecting container, and the inflow port allows the airflow containing dust to flow in along the tangential direction of the circumference. The swirling airflow is formed in the dust collecting container by the air flowing in from the inlet. [0003] A circular filter in plan view is disposed on an opening surface...
