Abstract

The invention provides an electric dust collector. A dust-collecting device of the electric dust collector comprises a structure configuring a primary filter (21) configured in the following manner: in the primary filter (21) provided with a plurality of through holes penetrating through an upstream side surface and a downstream side surface of the primary filter (21), a direction of a central axis and a forward direction of an outer side swirling airflow (61) flowing on the upstream side surface of the primary filter (21) form a second inclined angle which is downward inclined opposite to the forward direction. The central axis is a straight line of connecting an opening center of a first etching hole and an opening center of a second etching hole. Therefore, a declining swirling airflow (61) going toward a direction of a dust-collecting chamber (33) can be generated in the inner circumference of the primary filter (21), so that the dust can be prevented from flying; and blockage of the filter can be prevented.

Description

technical field [0001] The invention relates to an electric vacuum cleaner, in particular to a dust collecting device of the electric vacuum cleaner. Background technique [0002] The dust collector of the recent cyclone cleaner has the structure disclosed, for example in Japanese Patent No. 4430118 (hereinafter referred to as "Patent Document 1"). [0003] The dust collecting device of the vacuum cleaner described in Patent Document 1 swirls the air sucked together with the dust from the suction piece in the cylindrical dust collecting part, and separates the dust mixed in the air by centrifugal force. Collect the separated coarse dust into the dust collection chamber under the cylindrical dust collection part. The fine dust after passing through the primary filter is collected by the secondary filter provided on the periphery of the primary filter, and the primary filter is formed by forming a plurality of minute through holes in a metal plate. In addition, the dust coll...
