Abstract

A cyclone type dust collecting apparatus for a vacuum cleaner includes a cyclone body having a cylindrical shape, open upper and lower ends and a contaminant outlet. Air and contaminants are drawn into the cyclone body through one open end of the cyclone body. The contaminants are separated from the air by centrifugal force and are discharged through the contaminant outlet, which is located proximate the other open end of the cyclone body. The apparatus further includes a contaminant receptacle for collecting the contaminants that have been discharged from the cyclone body. The contaminant receptacle has open upper and lower ends and surrounds the cyclone body. A base member is connected to and closes the lower end of the cyclone body and the contaminant receptacle, and a cover is removably connected to the upper end of the cyclone body and the contaminant receptacle. The cover includes an air inlet and an air outlet, both of which communicate with the cyclone body. The cover further includes a contaminant separating grill that has a plurality of fine holes. The grill extends downward from the air outlet and into the cyclone body. The apparatus further includes a partition that is disposed between the cyclone body and the contaminant receptacle for restricting the movement of the contaminants in the contaminant receptacle.

Claims

1. A cyclone type dust collecting apparatus for a vacuum cleaner comprising:

a cyclone body having a cylindrical shape, open upper and lower ends and a contaminant outlet, one of the open ends allowing air and contaminants into the cyclone body, the contamination outlet being located proximate the other of the open ends and allowing contaminants that have been separated from the air by centrifugation to pass through;

a contaminant receptacle for collecting the contaminants discharged through the contaminant outlet, the contaminant receptacle having open upper and lower ends and surrounding the cyclone body;

a base member connected to and closing the lower end of the cyclone body and the contaminant receptacle;

a cover removably connected to upper end of the cyclone body and the contaminant receptacle, the cover having an air inlet and an air outlet in communication with the cyclone body, the cover further including a contaminant separating grill having a plurality of fine holes formed therein, the grill extending downward from the air outlet into the cyclone body; and

a partition disposed between the cyclone body and the contaminant receptacle, the partition restricting the movement of the contaminants in the contaminant receptacle.

2. The apparatus as claimed in claim 1, wherein the partition is proximate one edge of the contaminant outlet and has the same height as that of the cyclone body and the contaminant receptacle.

3. The apparatus as claimed in claim 1, wherein the cyclone body and the contaminant receptacle are of the same height and communicate with each other through the contaminant outlet exclusively.

4. The apparatus as claimed in claim 1, wherein the cyclone body, the contaminant receptacle, and the base member are integrally formed.

5. The apparatus as claimed in claim 1, further comprising reverse flow preventing means for preventing a reverse flow of the contaminants in the contaminant receptacle through the contaminant outlet and back into the cyclone body.

6. The apparatus as claimed in claim 5, wherein the reverse flow preventing means comprises a guide member extending from the outer surface of the cyclone body to an inner portion of the contaminant receptacle.
