Problems solved by technology

The problem at this time is the expansion of space and air leakage. In any case, it needs a substantial improvement of its own structure and needs space.
In addition, because the conventional dust removal device is placed in front of the electric blower, the dust removal device itself becomes a ventilation resistance, reducing the suction force.

Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0050] First, the outline of the electric vacuum cleaner will be described in order of FIGS. 1 to 10 .

[0051] As shown in FIGS. 1-3 , the main body casing of the electric vacuum cleaner has an upper main body casing 1 and a lower main body casing 2 . The main body casing has wheels 3 and casters (not shown) for walking. The upper cover 4 is mounted on the upper main body shell 1 in a freely switchable manner. After the upper cover 4 is opened, the dust collecting unit 5 can be loaded into or taken out from the storage part 6 of the dust collecting unit of the main body casing.

[0052] As shown in FIGS. 4-8 , the dust collection unit 5 has a dust collection box 7 and a corrugated dust collection filter 8 . A cyclone type dust collecting part is provided inside the dust collecting box 7 . The cyclone dust collection unit has a cyclone separation chamber 20 and a du...

Abstract

The invention provides a compact vacuum cleaner having no useless space and less in ventilation loss. The vacuum cleaner includes: a waveform dust collecting filter; and a dirt removal rotary body for adding a dirt removal vibration to the rear surface of a dust collection surface in the dust collecting filter when rotation is performed. The dirt removal rotary body is arranged so that the rotation axis follows the waving direction of the dust collecting filter. The rotary body is provided with a helical spring for adding the vibration, so as to be rotated by the rotation of a cord reel.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner provided with a dust removing device for removing dust adhering to a dust collecting filter. Background technique [0002] The structure of a general electric vacuum cleaner is, for example, as shown in Patent Document 1-Japanese Patent No. 3490081, the dust-laden air sucked from the suction port is introduced into the electric vacuum cleaner itself, and the dust is captured by the dust collecting part in the electric vacuum cleaner itself. , to expel the cleaned air outside the vacuum cleaner itself. [0003] The dust collection part has a method of capturing dust through a paper filter and discharging the cleaned air outside the vacuum cleaner itself; a method of capturing dust through the filtration of the dust collection filter and discharging the cleaned air outside the vacuum cleaner itself; and The cyclone separation method separates the clean air and dust through the centrifugal separ...
