Abstract

A cyclone separating apparatus for a vacuum cleaner includes a first cyclone with an air entrance disposed on a lower portion of the first cyclone and an air exit disposed at an upper portion of the first cyclone; a first contaminants chamber substantially enclosing the first cyclone to collect contaminants discharged from the first cyclone; a plurality of second cyclones above the first cyclone, the plurality of second cyclones being substantially perpendicular to a center axis of the first cyclone; and a second contaminants chamber disposed outside the first contaminants chamber to collect contaminants discharged from the plurality of second cyclones.

Claims

1. A cyclone separating apparatus for a vacuum cleaner comprising:

a first cyclone with an air entrance disposed on a lower portion of the first cyclone and an air exit disposed at an upper portion of the first cyclone;

a first contaminants chamber substantially enclosing the first cyclone to collect contaminants discharged from the first cyclone;

a plurality of second cyclones located above the first cyclone, the plurality of second cyclones being substantially perpendicular to a center axis of the first cyclone; and

a second contaminants chamber disposed outside the first contaminants chamber to collect contaminants discharged from the plurality of second cyclones.

2. The cyclone separating apparatus of claim 1, wherein each of the second cyclones comprises:

a body part formed in a substantially hollow cylindrical shape with a first portion and an opposite second portion opposite the first portion, the body part disposed so that a center axis of the body part is substantially perpendicular to the center axis of the first cyclone;

a second air entrance disposed in a tangential direction to the first portion of the body part;

a second air exit disposed coaxially with the body part at the first portion of the body part; and

a second contaminants outlet disposed at the opposite second portion of the body part.

3. The cyclone separating apparatus of claim 1, wherein air discharged from the plurality of second cyclones is discharged through an upper side of the cyclone separating apparatus.

4. The cyclone separating apparatus of claim 1, wherein air discharged from the plurality of second cyclones is discharged through a lower side of the cyclone separating apparatus.

5. The cyclone separating apparatus of claim 1, wherein the second contaminants chamber further comprises a plurality of contaminants collecting boxes corresponding to the plurality of second cyclones.

6. A cyclone separating apparatus for a vacuum cleaner comprising:

a first cyclone with an air entrance disposed on a lower portion of the first cyclone and an air exit disposed at an upper portion of the first cyclone;

a first contaminants chamber substantially enclosing the first cyclone to collect contaminants discharged from the first cyclone;

a plurality of second cyclones disposed to be inclined upwardly with respect to a top plane of the first cyclone; and

a second contaminants chamber disposed outside the first contaminants chamber to collect contaminants discharged from the plurality of second cyclones.

7. The cyclone separating apparatus of claim 6, wherein each of the second cyclones further comprises:

a body part formed in a substantially hollow cylindrical shape with a first portion and an opposite second portion opposite the first portion, the body part disposed so that a center axis of the body part is upwardly inclined with respect to the top plane of the first cyclone;

a second air entrance disposed in a tangential direction to the first portion of the body part;

a second air exit disposed coaxially with the body part at the first portion of the body part; and

a second contaminants outlet disposed at the opposite second portion of the body part.

8. The cyclone separating apparatus of claim 6, wherein air discharged from the plurality of second cyclones is discharged through an upper side of the cyclone separating apparatus.

9. The cyclone separating apparatus of claim 6, wherein air discharged from the plurality of second cyclones is discharged through a lower side of the cyclone separating apparatus.

10. The cyclone separating apparatus of claim 6, wherein the second contaminants chamber comprises a plurality of contaminants collecting boxes corresponding to the plurality of second cyclones.

11. A cyclone separating apparatus for a vacuum cleaner comprising:

a first cyclone unit including,

a first cyclone with an air entrance disposed on a lower portion of the first cyclone and an air exit disposed at an upper portion of the first cyclone,

a first contaminants chamber substantially enclosing the first cyclone to collect contaminants discharged from the first cyclone, and

a second contaminants chamber disposed outside the first contaminants chamber; and

a second cyclone unit including,

a plurality of second cyclones disposed above the first cyclone unit and substantially perpendicular to a center axis of the first cyclone,

a discharging air gathering member in fluid communication with the plurality of second cyclones, and

a housing substantially enclosing the plurality of second cyclones.

12. The cyclone separating apparatus of claim 11, wherein each of the second cyclones further comprises:

a body part formed in a substantially hollow cylindrical shape with a first portion and an opposite second portion opposite the first portion, the body part disposed so that a center axis of the body part is substantially perpendicular to the center axis of the first cyclone;

a second air entrance disposed in a tangential direction to the first portion of the body part;

a second air exit disposed coaxially with the body part at the first portion of the body part; and

a second contaminants outlet disposed at the opposite second portion of the body part.

13. The cyclone separating apparatus of claim 12, wherein the second air exit of each of the second cyclones is radially connected with the discharging air gathering member.

14. The cyclone separating apparatus of claim 13, wherein the discharging air gathering member is formed so that air is discharged through an upper side of the second cyclone unit.

15. The cyclone separating apparatus of claim 13, wherein the discharging air gathering member is formed so that air is discharged through a lower side of the first cyclone unit.

16. The cyclone separating apparatus of claim 15, further comprising a second air discharging pipe disposed at a center of the first cyclone.

17. The cyclone separating apparatus of claim 11, further comprising:
