Electric dust collector

Abstract

The invention solves the problems that the contact time of a deodorization filter and exhaust air becomes short, deodorization efficiency is low and an odor can not be substantially reduced because the suction amount of a cleaner is large though the deodorization filter is loaded in a conventional vacuum cleaner. The vacuum cleaner comprises a dust collecting part for gathering dust, a motor-driven blower, a cord reel, and a deodorant housing part provided on a ventilation more upstream than the dust collecting part for housing a deodorant, and vibrations are added to the deodorant housing part in linkage with the winding operation or pull-out operation of the cord reel and the deodorant is fed into the dust collecting part. Thus, the deodorant is directly fed to sucked dust in linkage with the winding operation or pull-out operation of the cord reel 22 and the odor of the dust is strongly removed.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, and more particularly, to an electric vacuum cleaner which reduces the peculiar smell of the exhaust gas by removing the peculiar smell in the inhaled dust with a deodorizing material and has a dust removal function. Background technique [0002] For the exhaust gas deodorization problem in the electric vacuum cleaner, someone once proposed the scheme that deodorization filter is installed in the exhaust channel. In recent years, the design scheme of deodorizing by the acidification of photocatalyst has also begun to appear (one example thereof can refer to Japanese Patent No. 3238055). [0003] In addition, some vacuum cleaners are also equipped with: a dust separator; a folded filter for trapping fine dust contained in the air passing through the dust separator; and a gear that rotates in conjunction with the rewinding operation of the power cord. and setting the protrusion on the gear.

Problems solved by technology

[0004] However, in the above-mentioned method of installing a deodorizing filter in the exhaust duct, since the suction volume of the electric vacuum cleaner is large, the contact time between the deodorizing filter and the exhaust air containing peculiar smell will become very short, Therefore, there are problems that the deodorization efficiency is low and the reduction degree of the peculiar smell is also small.

[0005] In addition, although dust accumulates on the surface of the filter in the direction opposite to the direction of air flow, the vibration applied to the filter is in the direction perpendicular to the folding direction, that is, from the direction of air flow. The direction is perpendicular to the direction, so the dust removal efficiency is poor

Moreover, since the filter is directly vibrated through the projections, the filter needs to be made very firm, and there is a problem of high manufacturing cost.
