Abstract

A filter assembly and a cyclone dust collecting apparatus using the same are provided. The filter assembly is employed by a cyclone dust collecting apparatus which centrifugally separates contaminant from drawn-in air to remove the contaminant and filters and discharges the air and has a filter part, and an air path. The air path is formed in the filter part to guide the air into the filter part and enables the air to flow in a three-dimensional direction, in other words, in a perpendicular direction to a central axis of the filter part, simultaneously flow in a parallel direction with the central axis of the filter part.

Claims

1. A filter assembly for a cyclone dust collecting apparatus that centrifugally separates contaminant from drawn-in air to remove the contaminant, and filters and discharges the air, comprising:

a filter part; and

an air path formed around the filter part to guide the drawn-in air into the filter part and allows a first portion of the drawn-in air to flow in a perpendicular direction to a central axis of the filter part and a second portion of the drawn-in air to flow in a parallel direction to the central axis.

2. The filter assembly according to claim 1, wherein the filter part comprises a conical configuration.

3. The filter assembly according to claim 2, wherein the filter part comprises a spiral member in a forward direction of a flowing direction of the drawn-in air.

4. The filter assembly according to claim 3, further comprising a connection part connected with an end of the filter part to connect with a cyclone body of the cyclone dust collecting apparatus.

5. The filter assembly according to claim 4, wherein the filter part is coaxially arranged and has a diameter that decreases in a direction away from the connection part.

6. The filter assembly according to claim 5, further comprising a supporting rib formed in a direction of the central axis of the filter part to support the filter part.

7. The filter assembly according to claim 2, wherein the filter part comprises a plurality of ring members each with a different diameter, the plurality of ring members being sequentially arranged in a direction of the central axis so as not to overlap each other.

8. The filter assembly according to claim 7, further comprising a connection part connected with a top end of the filter part to connect with the cyclone body of the cyclone dust collecting apparatus.

9. The filter assembly according to claim 8, wherein the plurality of ring members are coaxially arranged so that a diameter of the filter part decreases in a direction away from the connection part.

10. The filter assembly according to claim 9, further comprising a supporting rib formed in a direction of the central axis of the filter part to support the plurality of ring members.

11. The filter assembly according to claim 8, further comprising a plurality of slits formed between the filter part and the connection part.

12. A cyclone dust collecting apparatus comprising:

a cyclone body with an air inlet for drawing in contaminant-laden air, an air outlet for discharging the air to the outside, and a cyclone chamber for separating contaminant from the air; and

a filter assembly formed in the cyclone chamber to filter the air discharged from the air outlet;

wherein the filter assembly comprises,

a connection part engaged with the air outlet,

a filter part connected with a bottom end of the connection part and being a reverse-conical configuration having a diameter that decreases in a direction away from the connection part, and

an air path formed around the filter part to guide the air into the filter part so that a first portion of the air to flows in a perpendicular direction to a central axis of the filter part and a second portion of the air flows in a parallel direction to the central axis.

13. The apparatus according to claim 12, wherein the cyclone chamber has a reverse-conical inner wall that corresponds to a shape of the filter part.

14. The apparatus according to claim 13, wherein the cyclone chamber comprises a primary cyclone chamber and a secondary chamber to centrifugally separate contaminant from the air in two steps,

and wherein the filter assembly is formed in the primary cyclone chamber and the reverse-conical inner wall is formed in the primary cyclone chamber.

15. The apparatus according to claim 12, wherein the filter part comprises a spiral structure formed in a forward direction of a flowing direction of the air.

16. The apparatus according to claim 12, wherein the filter part comprises a plurality of ring members each with a different diameter, the plurality of ring members being sequentially and coaxially arranged in a direction of the central axis of the filter part so as not to overlap each other.

17. The apparatus according to claim 16, wherein the filter assembly further comprises a plurality of slits formed between the filter part and the connection part.

18. The apparatus according to claim 12, wherein the filter assembly further comprises a supporting rib formed in a direction of the central axis of the filter part to support the filter part.
