Electric cleaner

Abstract

An electric cleaner where a lower mesh filter (34) can have a sufficient area with the cleaner made to be a space saving one. A communication opening (35) is formed in a partition wall (26) positionedbetween a wind passage (31) for rough dust and a wind passage (32) for fine dust, and the lower mesh filter (34) is placed in the communication opening (35). The wind passage (31) for rough dust is the passage through which rough dust that is separated in a separation section (16) and passed through a separation main section (17) having a substantially linear hollow-cylindrical shape passes together with suction wind. The wind passage (32) for fine dust is the passage through which the suction wind passes together with fine dust that is separated in the separation section (16) and passed through an auxiliary opening (18). The communication opening (35) is the opening through which the suction wind flowed into the rough dust wind passage (31) is vented, and the communication opening is formed along the rough dust wind passage (31). The structure enables the lower mesh filter (34) to easily have a sufficient area, and this is achievable without the increase in a cross-sectional area ofthe wind passage (31) for rough dust and in the size of a cleaner body (2) etc. and with the cleaner body formed to be a space saving one.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner having a separation unit that can be driven by an electric blower (blower) to separate dust sucked together with air. Background technique [0002] Heretofore, such electric vacuum cleaners have a vacuum cleaner body that accommodates the electric blower. In the main body of the vacuum cleaner, a separation part is arranged, which communicates with the suction port of the main body formed by opening on the main body of the vacuum cleaner. The separation unit cyclone-separates the dust sucked together with the air from the main body suction port by the electric blower according to specific gravity or size. Further, on the downstream side of the separation part, an opening part communicating with the air passage connected to the suction side of the electric blower is provided, and a filter part is provided in the opening part. And the dust that is driven by the electric blower and sucked toget...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned electric vacuum cleaner that separates coarse dust and fine dust and collects dust, such as inertial separation, it is easy to clog the filter part due to fine dust, and it is necessary to ensure a large filter area.

[0005] However, in order to increase the filter area, it is necessary to increase the cross-sectional area of ​​the separation part or the air passage, and there is a problem that it is difficult to secure an enlarged filter area without enlarging the main body of the vacuum cleaner.
