Abstract

A dust separating apparatus for a vacuum cleaner is provided. The dust separating apparatus includes a cyclone configured to provide a plurality of cyclone airflows therein and a dust container provided separate from the cyclone. The cyclone includes a first air inlet configured to receive an airflow containing dust and a dust outlet configured to discharge dust separated by the plurality of cyclone airflows. The dust outlet is located in a central portion of the cyclone. The dust container is removably placeable into communication with the dust outlet to collect dust separated in the cyclone. A vacuum cleaner including the dust separating apparatus is also provided.

Claims

1. A dust separating apparatus for a vacuum cleaner, the dust separating apparatus comprising:

a cyclone configured to provide a plurality of cyclone airflows therein, the cyclone including;

a first air inlet configured to receive an airflow containing dust; and

a dust outlet configured to discharge dust separated by the plurality of cyclone airflows, the dust outlet being located in a central portion of the cyclone; and

a dust container provided separate from the cyclone, the dust container being removably placeable into communication with the dust outlet to collect dust separated in the cyclone.

2. The dust separating apparatus of claim 1, wherein the dust container has an upper surface and a dust inlet in the upper surface, the dust inlet being arranged opposite the dust outlet of the cyclone when placed into communication with the dust outlet.

3. The dust separating apparatus of claim 1, wherein the cyclone include a body in which air flows along an inner surface thereof, the body having a pair of spaced apart ends defining side surfaces of the cyclone, and the dust outlet extends outward from the body.

4. The dust separating apparatus of claim 1, wherein the cyclone includes a second air inlet configured to receive an air flow containing dust, the second air inlet is spaced from the first air inlet, and the dust outlet is disposed between the first and second air inlets.

5. The dust separating apparatus of claim 1, wherein the dust container comprises

a dust body defining a dust storage, and

a cover member for opening and closing the dust storage, the cover member including a dust inlet formed therein for the dust separated in the cyclone to enter therethrough.

6. The dust separating apparatus of claim 1, further comprising an air return passage configured to return air that enters the dust container to the dust separating unit.

7. The dust separating apparatus of claim 6, wherein the dust separating unit includes a passage guide to divide the dust outlet into a dust outlet passage and an air return passage.

8. The dust separating apparatus of claim 1, wherein the dust container defines a dust storage, the dust container includes a partition in the dust storage, and the dust container includes a compressing member configured to compress dust in the dust storage by pressing the dust between the compression member and the partition.

9. The dust separating apparatus of claim 8, wherein the compressing member includes a rotatable shaft and a compressing plate extending from the rotatable shaft.

10. The dust separating apparatus of claim 9, wherein the compression member includes a second compressing plate extending from the rotatable shaft.

11. The dust separating apparatus of claim 9, wherein the dust container includes a fixing shaft located in the dust storage to rotatably support the rotatable shaft.

12. The dust separating apparatus of claim 11, wherein the rotatable shaft includes a first end received in the fixing shaft.

13. The dust separating apparatus of claim 12, wherein the dust container includes a driven gear connected to the first end of the rotatable shaft, and the driven gear is located at an exterior surface of the dust container.

14. A vacuum cleaner comprising:

a vacuum cleaner main body;

a cyclone located in the vacuum cleaner main body, the cyclone being configured to provide a plurality of cyclone airflows therein, the cyclone including;

a first air inlet configured to receive an airflow containing dust; and

a dust outlet configured to discharge dust separated by the plurality of cyclone airflows, the dust outlet being located in a central portion of the cyclone; and

a dust container provided separate from the cyclone, the dust container being removably placeable into communication with the dust outlet to collect dust separated in the cyclone.

15. The vacuum cleaner of claim 14, wherein the dust container has an upper surface and a dust inlet in the upper surface, the dust inlet being arranged opposite the dust outlet of the cyclone when placed into communication with the dust outlet.

16. The vacuum cleaner of claim 14, wherein the cyclone include a body in which air flows along an inner surface thereof, the body having a pair of spaced apart ends defining side surfaces of the cyclone, and the dust outlet extends outward from the body.

17. The vacuum cleaner of claim 14, wherein the dust container comprises

a dust body defining a dust storage, and

a cover member for opening and closing the dust storage, the cover member including a dust inlet formed therein for the dust separated in the cyclone to enter therethrough.

18. The vacuum cleaner of claim 14, wherein the cyclone includes a second air inlet configured to receive an air flow containing dust, the second air inlet is spaced from the first air inlet, and the dust outlet is disposed between the first and second air inlets.

19. The vacuum cleaner according to claim 18, further comprising a distribution unit configured to separate airflow into the vacuum cleaner into two separate passages, each passage being in communication with one of the first and second air inlets.

20. The vacuum cleaner according to claim 19, wherein the distribution unit is integrally formed with the dust container.

21. The vacuum cleaner according to claim 20, wherein the distribution unit includes one air inlet and a pair of air outlets.

22. The vacuum cleaner according to claim 19, wherein the dust container includes a first space and a second space separated by a partition, the air discharged from the first space enters the distribution unit, and the second space stores dust separated in the cyclone.
