Abstract

A vacuum cleaner includes a cleaner main body, a suction device, a suction motor, and a dust container. The dust container includes a dust collection body configured to contain dust, an opening/closing portion rotatably coupled to the dust collection body and configured to rotate to thereby open and close at least a portion of the dust collection body, and an operation portion connected to the dust collection body and configured to rotate in both a first direction and a second direction opposite the first direction. The opening/closing portion is configured to rotate based on the operation portion rotating in the first direction, and configured to rotate based on the operation portion rotating in the second direction.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a cleaner main body;
a suction device configured to suction dust-containing air and to guide the suctioned dust-containing air to the cleaner main body;
a suction motor located within the cleaner main body and configured to provide suction force; and
a dust container configured to receive dust that has been suctioned through the suction device, the dust container including:
a dust collection body configured to contain the dust,
an opening/closing portion rotatably coupled to the dust collection body and configured to rotate to thereby open and close at least a portion of the dust collection body, and
an operation portion connected to the dust collection body and configured to rotate in both a first direction and a second direction opposite the first direction,

wherein the operation portion is configured, based on rotating in the first direction, to cause the opening/closing portion to rotate to open at least the portion of the dust collection body, and further configured, based on rotating in the second direction, to cause the opening/closing portion to rotate to open at least the portion of the dust collection body.

2. The vacuum cleaner according to claim 1 , further comprising:
a first elastic member that is configured, based on the operation portion rotating in the first direction, to be compressed; and
a second elastic member that is configured, based on the operation portion rotating in the second direction, to be compressed.

3. The vacuum cleaner according to claim 2 , wherein the dust collection body includes a first support portion that supports a first end of each of the first and second elastic members, and
wherein the operation portion includes a second support portion that supports a second end of each of the first and second elastic members.

4. The vacuum cleaner according to claim 3 , wherein the operation portion has an arch shape and further includes a third support portion, and
wherein the first, second, and third support portions define an elastic member accommodation portion that accommodates each of the first and second elastic members.

5. The vacuum cleaner according to claim 1 , wherein the operation portion includes:
an operation body;
a protrusion portion that protrudes from a rim of the operation body, the protrusion portion having a pair of ends that are spaced apart from each other; and
a pair of inclined portions, each of the pair of inclined portions extending from each of the pair of ends of the protrusion portion.

6. The vacuum cleaner according to claim 5 , wherein the dust collection body includes a fixing protrusion,
wherein the opening/closing portion includes a fixing portion that is configured, based on the dust collection body closing the dust collection body, to couple to the fixing protrusion, and
wherein, based on the opening/closing portion closing the dust collection body, a portion of the fixing portion is positioned in a space defined between the pair of inclined portions.

7. The vacuum cleaner according to claim 6 , wherein the fixing portion includes:
an interference portion that is configured, based on the rotation of the operation portion, to interfere with one of the pair of inclined portions; and
a hooking portion that protrudes from the interference portion toward the dust collection body, the hooking portion being configured to selectably couple to the fixing protrusion,
wherein the hooking portion is configured to be uncoupled from the fixing protrusion based on one of the pair of inclined portions pressing the interference portion to a predetermined position, and
wherein the fixing portion is configured, based on one of the pair of inclined portions pressing the interference portion, to become spaced apart from the fixing protrusion to thereby uncouple the hooking portion from the fixing protrusion.

8. The vacuum cleaner according to claim 7 , wherein each of the pair of inclined portions includes:
a first inclined surface facing a front lower side;
a second inclined surface facing a front upper side; and
a boundary portion defined between the first inclined surface and the second inclined surface, and
wherein the boundary portion is configured, based on the operation portion rotating in the first direction or the second direction, to contact the fixing portion before the first inclined surface contacts the fixing portion.

9. The vacuum cleaner according to claim 7 , wherein the fixing portion has an end that is spaced apart from a surface of the dust collection body based on the opening/closing portion closing the dust collection body.

10. The vacuum cleaner according to claim 7 , wherein the fixing portion is configured, based on one of the pair of inclined portions pressing the interference portion, to elastically deform to thereby become spaced apart from the fixing protrusion.

11. The vacuum cleaner according to claim 7 , wherein, based on the hooking portion being coupled to the fixing protrusion, the hooking portion is located vertically above the fixing protrusion.

12. The vacuum cleaner according to claim 6 , wherein the operation portion is located vertically above the fixing protrusion.

13. The vacuum cleaner according to claim 5 , wherein the operation body includes a handle configured to be gripped by a user.

14. The vacuum cleaner according to claim 5 , wherein the operation portion further includes a center portion located in the operation body, and
wherein the center portion defines a hole configured to receive a fastening member.

15. The vacuum cleaner according to claim 1 , wherein the dust collection body defines an opening at a bottom portion, and
wherein the opening/closing portion is configured to open and close the opening at the bottom portion.

16. The vacuum cleaner according to claim 15 , wherein the dust collection body includes a hinge at the bottom portion, and
wherein the opening/closing portion includes a hinge portion that protrudes from a first position at a circumference of the opening/closing portion, the hinge portion being configured to couple to the hinge.

17. The vacuum cleaner according to claim 16 , wherein the opening/closing portion includes a fixing portion that protrudes from a second position at the circumference opposite the first position, the operation portion facing toward the hinge portion.

18. The vacuum cleaner according to claim 1 , wherein the operation portion is configured to rotate in both the first direction and the second direction about a rotation axis that passes through the dust collection body.

19. The vacuum cleaner according to claim 1 , wherein the operation portion is configured to:
based on rotating in the first direction from a reference position, cause the opening/closing portion to rotate to open at least the portion of the dust collection body; and
based on rotating in the second direction from the reference position, cause the opening/closing portion to rotate to open at least the portion of the dust collection body.

20. A vacuum cleaner comprising:
a cleaner main body;
a suction device configured to suction dust-containing air and to guide the suctioned dust-containing air to the cleaner main body;
a suction motor located within the cleaner main body and configured to provide suction force; and
a dust container configured to receive dust that has been suctioned through the suction device, the dust container including:
a dust collection body configured to contain the dust, the dust coll
