Abstract

A cyclone dust collector comprises a cyclone body including a cyclone chamber, a connection path and a dust chamber, wherein the cyclone chamber and the dust chamber are arranged in parallel, a cover unit connected to an upper part of the cyclone body and having a suction path for external air to flow in therethrough, and a backflow prevention member disposed at one sidewall of the dust chamber to prevent collected dust from flowing to the cyclone chamber.

Claims

1. A cyclone dust collector comprising:

a cyclone body including a cyclone chamber, a connection path, and a dust chamber, wherein the cyclone chamber and the dust chamber are arranged in parallel;

a cover unit connected to an upper part of the cyclone body and having a suction path for external air to flow therethrough; and

a backflow prevention member disposed at one sidewall of the dust chamber to prevent collected dust from flowing to the cyclone chamber.

2. The cyclone dust collector of claim 1, wherein the backflow prevention member is mounted at a right wall of the dust chamber as a partition between the dust chamber and the connection path.

3. The cyclone dust collector of claim 2, wherein the backflow prevention member covers approximately 30 to 50% of a top area of the dust chamber.

4. The cyclone dust collector of claim 3, wherein the backflow prevention member has a substantially arc-shaped section.

5. The cyclone dust collector of claim 4, wherein the backflow prevention member is inclined toward a bottom of the dust chamber.

6. The cyclone dust collector of claim 5, wherein the backflow prevention member has a first length and the dust chamber has a second length, the first and second lengths being substantially in the ratio of 0.8:

1 to 0.9;

1, and wherein the backflow prevention member has a first width and the dust chamber has a second width, the first and second widths being substantially in the ratio of 0.4;

1 to 0.5;

1.

7. A vacuum cleaner comprising:

a cyclone chamber having an upper part;

a dust chamber arranged in parallel with the cyclone chamber;

a cover unit having a suction path for external air, the cover unit being connected to the upper part; and

a backflow prevention member disposed at a sidewall of the dust chamber to prevent collected dust in the dust chamber from flowing to the cyclone chamber.

8. The vacuum cleaner of claim 7, wherein the backflow prevention member covers approximately 30 to 50% of a top area of the dust chamber.

9. The vacuum cleaner of claim 7, wherein the backflow prevention member has a substantially arc-shaped section.

10. The vacuum cleaner of claim 7, wherein the backflow prevention member is inclined toward a bottom of the dust chamber.

11. The vacuum cleaner of claim 7, wherein the backflow prevention member has a first length and the dust chamber has a second length, the first and second lengths being substantially in the ratio of 0.8:

1 to 0.9;

1.

12. The vacuum cleaner of claim 7, wherein the backflow prevention member has a first width and the dust chamber has a second width, the first and second widths being substantially in the ratio of 0.4:

1 to 0.5;

1.

13. The vacuum cleaner of claim 7, wherein the backflow prevention member is inclined toward a bottom of the dust chamber by an angle of approximately 20°

to 25°
