Abstract

The present disclosure relates to a dust separating apparatus using a centrifugal force. The dust separating apparatus includes a cyclone body configured to separate dust from air using centrifugal force, and having an entering pipe through which the air enters; a dust collecting receptacle configured to be detachably connected to a bottom end of the cyclone body, and for collecting dust separated from the air; and a filter unit configured to be detachably disposed to the cyclone body, wherein the filter unit has a compact, at least double structure formed by a filter for filtering large dust and a filter for filtering fine dust.

Claims

1. A dust separating apparatus comprising:

a cyclone body configured to separate dust from air using centrifugal force, the cyclone body having an entering pipe through which the air enters;

a dust collecting receptacle configured to be detachably connected to a bottom end of the cyclone body, the duct collecting receptacle collecting dust separated from the air; and

a filter unit configured to be detachably disposed to the cyclone body,

wherein the filter unit has a compact, at least double structure formed by a first filter for filtering large dust and a second filter for filtering fine dust.

2. The dust separating apparatus of claim 1, wherein the first filter comprises a grill filter for filtering large dust and the second filter comprises a porous filter disposed inside the grill filter.

3. The dust separating apparatus of claim 2, wherein the filter unit further comprises a supporting member for supporting the porous filter.

4. The dust separating apparatus of claim 3, wherein each of the grill filter, the porous filter, and the supporting member is formed in a substantially cylindrical shape with an air flowing path thereinside.

5. The dust separating apparatus of claim 3, wherein the porous filter is disposed between the grill filter and the supporting member,

wherein the supporting member is configured to be mounted on or separated from the grill filter.

6. The dust separating apparatus of claim 2, wherein the grill filter comprises:

a grill part through which the air enters; and

a cylindrical part disposed above the grill part and through which the air cannot enter.

7. The dust separating apparatus of claim 6, wherein the grill filter further comprises:

a locking part disposed at a top end of the cylindrical part and configured to be connected to or separated from the cyclone body.

8. The dust separating apparatus of claim 2, wherein the grill filter further comprises:

a skirt projecting from a bottom end of a circumferential surface of the grill filter and preventing dust from flowing back.

9. The dust separating apparatus of claim 1, wherein at least a part of the entering pipe projects from a top surface of the cyclone body.

10. The dust separating apparatus of claim 1, wherein the dust collecting receptacle comprises a discharging pipe projecting from a center of a bottom surface of the dust collecting receptacle, and

wherein the discharging pipe is detachably connected to a bottom end of the filter unit so as to guide the air flowing out the filter unit to be discharged outside.

11. A dust separating apparatus comprising:

a cyclone body configured to separate dust from air using a whirling air current, the cyclone body having a top surface and a bottom end;

an entering pipe through which the air enters the cyclone body, at least a part of the entering pipe projecting from the top surface;

a dust collecting receptacle configured to be detachably connected to the bottom end;

a discharging pipe projecting upwardly from a center of the inside of the dust-collecting receptacle, the cyclone body being is in fluid communication with an outside via the discharging pipe;

a filter unit configured to be detachably disposed on the discharging pipe within the cyclone body, the filter unit having a grill filter for filtering large dust and a porous filter disposed inside the grill filter for filtering fine dust.

12. The dust separating apparatus of claim 11, wherein the grill filter comprises:

a grill part through which the air enters; and

a cylindrical part disposed above the grill part and through which the air cannot enter.

13. The dust separating apparatus of claim 12, wherein the grill part further comprises a plurality of blades having a flow path defined between each of the plurality of blades.

14. The dust separating apparatus of claim 13, wherein the plurality of blades are inclined in a direction opposite the whirling air current.
