Abstract

An electric vacuum cleaner (10) includes a first dust separation device (F3) configured to separate sucked dust, a first dust collection section (60) for collecting the separated dust, a second dust separation device (100) configured to separate the dust, a dust removing device (90) configured to remove the dust adhering to the second dust separation device (100), a second dust collection section (74) for accumulating the removed dust, a partition wall (61) for zoning the first dust collection section (60) and the second dust collection section (74) and an introduction opening (75) for introducing the removed dust into the second dust collection section (60); the partition wall (61) includes a communication opening (63) for communicating the first dust collection section (60) to the second dust collection section (74) and an opening and closing member (76) for closing either of the introduction opening (75) or the communication opening (63) and switching the closing to the other by rotating, and the opening and closing member (76) closes the introduction opening (75) with a negative pressure by an electric fan (33) and closes the communication opening (63) by its own weight when the electric fan (33) is not driven.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner including first and second dust separation devices for separating suctioned dust. Background technique [0002] In the prior art, there is known an electric vacuum cleaner comprising a first dust separation device and a second dust separation device, wherein the first dust separation device separates the dust, and the second dust separation device passes through the first dust separation device. Dust is separated by a dust separation device (see Patent Document 1). [0003] The electric vacuum cleaner includes: a first dust separation device that separates the dust attracted by the negative pressure of the electric blower; a first dust collection unit that collects the dust separated by the first dust separation device; A dust separation device, which separates the dust passing through the first dust separation device; a dust removal device, which removes the dust attached to the second dust ...
