Description

Dust compression dust collector {DUST COLLECTING APPARATUS WITH DUST COMPRESSOR}

The present invention relates to a dust compression type dust collector that can compress dust without deteriorating dust collection efficiency when compressing dust collected in the dust container to increase the dust collecting capacity of the dust container.

In order to eliminate the hassle and cost of replacing the dust bag of the vacuum cleaner, a dust container is provided. Centrifugal (cyclone) vacuum cleaners, which do not require envelopes, have become widespread.

However, such a centrifugal vacuum cleaner still hassle to empty the dust collected in the dust box.

Accordingly, in order to eliminate the hassle of frequently emptying dust, a compressed dust collector has been developed that increases the relative dust capacity of the dust container by compressing the collected dust.

As an example of the above-described compressed dust collector, a compression member, which is an auger screw member having a downward inclined surface, is positioned inside the waste container of a vacuum cleaner to compress the collected dust.

Can be mentioned.

However, in the above-described prior art, when the downwardly inclined surface or the spiral compression ribs of the compression member are viewed from the top, they overlap each other, thereby not forming a space in direct communication from the top of the compression member to the bottom. Accordingly, the dust separated by the centrifuge is not moved quickly to the bottom of the waste container or the dust collecting body and stays in the upper part for a long time. The upper residual persistence of the dust flows back to the inside of the centrifuge due to the remaining dust flows back, and the efficiency of the separation of the dust is reduced, as well as the grill is blocked by the dust, causing a failure.

In addition, since the driving motor is positioned in the upper part of the above-described conventional compression dust collector, the center of gravity of the device equipped with the compression dust collector of the vacuum cleaner is moved upward so that the overall operation of the vacuum cleaner is not easily controlled. There is also a problem.
