Abstract

According to the present invention, there can be provided an electric vacuum cleaner with excellent maintenance property, wherein: since dusts are compressed inside a bevel part, collected amount of dusts can be increased and floating return of dusts from a dust collection accumulation part to a collection separation part is suppressed, dust separation properties are improved and hair is prevented from being tangled to an air intake part; since dusts are compressed inside the bevel part, upward floating of dusts is suppressed during discharge of dusts; and since dusts adhered to a bypass filter (filter 2) are discharged simultaneously with the disposal of dusts, labor for filter cleaning can be reduced. A dust collection device for this electric vacuum cleaner has: an air intake part having a substantially cylindrical first filter on an upper section of an inner barrel; and an opened bevel part below the air intake part, wherein the air intake part and the bevel part communicate with each other via a second filter, and the bevel part is provided with a sliding mechanism that protrudes toward an opening when a bottom lid is open.

Description

technical field [0001] The present invention relates to electric vacuum cleaners. Background technique [0002] In the prior art, there are roughly two types of dust collectors, such as paper bag-type dust collectors that compress suctioned garbage in paper bags, and cyclone-type dust collectors that use swirling air to centrifuge and store them in dust collectors. A dust collection method. Since the cyclone method generates swirling airflow, the maintenance workload of the dust collector tends to increase compared with the paper bag method. [0003] In Japanese Patent Application Laid-Open No. 2007-167450 (Patent Document 1), a dust collecting unit of an electric vacuum cleaner is described, which has a rotating chamber that separates the suctioned dust and the suction wind due to centrifugal force, and is located between the rotating chamber and the electric fan. And the filter chamber for filtering the suction wind after passing through the whirling chamber, and the dus...
