Abstract

A dust separating apparatus for a vacuum cleaner having a casing, a cyclone unit formed in the casing to filter contaminants from drawn-in air and discharge air removed of the contaminants, and a dust collection part arranged in parallel with the cyclone unit in the casing to collect the contaminant separated from the air by the cyclone unit. The casing is substantially semicircular to correspond to the mounting chamber of the vacuum cleaner body. On a bottom surface of the cyclone unit, an air inlet and an air outlet are formed. The air outlet is formed at one side of the air inlet.

Claims

1. A dust separating apparatus detachably engaged with a mounting chamber of a vacuum cleaner body, comprising:

a casing;

a cyclone unit formed in the casing to filter contaminants from drawn-in air and discharge air removed of the contaminants; and

a dust collection part arranged in parallel with the cyclone unit in the casing to collect the contaminants separated from the air by the cyclone unit,

wherein the casing is substantially semicircular to correspond to the mounting chamber of the vacuum cleaner body.

2. The apparatus according to claim 1, wherein the cyclone unit comprises:

a cyclone body forming a cyclone chamber and having a lower height than the casing; and

an air inlet and an air outlet formed on a bottom surface of the cyclone body,

wherein the dust collection part is formed on an outer circumference surface of the cyclone body to surround the cyclone body.

3. The apparatus according to claim 2, wherein the cyclone body further comprises a guide member configured on an inner wall in a spiral configuration to guide air drawn in via the air inlet to form an ascending stream in the cyclone chamber.

4. The apparatus according to claim 3, further comprising a cover detachably engaged with a top portion of the casing.

5. A dust separating apparatus detachably engaged with a mounting chamber of a vacuum cleaner body, comprising:

a casing being substantially semicircular to correspond to the mounting chamber;

a cyclone unit formed in a central portion in the casing and having an air inlet and an air outlet at a bottom surface;

a dust collection part arranged in parallel with the cyclone unit in the casing to collect a contaminant separated from drawn in air by the cyclone unit; and

a cover detachably engaged with a top portion of the casing and forming a dust discharge opening in cooperation with the cyclone unit.

6. A vacuum cleaner comprising:

a body;

a mounting chamber in the body;

a dust separating apparatus comprising a casing, a cyclone unit, and a dust collection part, the dust separating apparatus being detachably engaged with the mounting chamber in the body so that a dead space between the cyclone unit and the mounting chamber is utilized by the dust collection part.

7. The vacuum cleaner according to claim 6, wherein the dust collection part surrounds the cyclone unit.

8. The vacuum cleaner according to claim 6, wherein the mounting chamber and the dust collection part are both substantially semicircular.

9. The vacuum cleaner according to claim 6, wherein the dust separating apparatus further comprises a cover being detachably engaged with the casing.

10. The vacuum cleaner according to claim 9, further comprising a counterflow prevention member protruding a predetermined distance from an inside portion of the cover.
