Abstract

A cleaner includes a first extension pipe connected to a suction portion contacting a surface to be cleaned, and a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe. The first and second extension pipes operate in a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other. Such configuration enables a user to increase cleaning efficiency.

Claims

1. A cleaner comprising:

a first extension pipe connected to a suction portion contacting a surface to be cleaned; and

a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe,

wherein the first and second extension pipes are configured to operate in;

a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other.

2. The cleaner according to claim 1, wherein the first and second extension pipes are configured to further operate in:

a third arrangement configured to rotate in a second direction opposite to the first direction from the first arrangement.

3. The cleaner according to claim 1, further comprising:

a link assembly configured to allow the second extension pipe to rotate about the first extension pipe.

4. The cleaner according to claim 3, wherein the link assembly includes:

a locking device configured to restrict or release rotation of the first and second extension pipes.

5. The cleaner according to claim 4, wherein the locking device includes:

a locking button configured to be pressurized;

a stopper pressurized by the locking button; and

a stopper receiver configured to allow the stopper to be inserted therein such that rotation of the second extension pipe is restricted, or configured to allow the stopper to be released therefrom such that restriction of the rotation of the second extension pipe is released.

6. The cleaner according to claim 5, wherein the locking button is configured to have a pressurization direction perpendicular to the first and second directions.

7. The cleaner according to claim 6, wherein the link assembly includes:

a stopper seating portion configured to extend from any one of the first and second extension pipes, and provided to allow the stopper to be seated therein such that movement of the stopper is restricted in the pressurization direction; and

a receiver seating portion configured to extend from the other one of the first and second extension pipes such that the stopper receiver is fixedly disposed therein.

8. The cleaner according to claim 6, wherein the link assembly further includes:

a stopper elastic member configured to allow the stopper to elastically return in a direction opposite to the pressurization direction.

9. The cleaner according to claim 5, wherein:

the locking button is one pair of locking buttons, the stopper is one pair of stoppers, and the stopper receiver is one pair of stopper receivers, and

the locking device includes a rotation shaft configured to interconnect the one pair of the stopper receivers as well as to form a rotation center of each of the first and second extension pipes.

10. The cleaner according to claim 9, wherein the rotation shaft is spaced apart from an inner passage of each of the first and second extension pipes.

11. The cleaner according to claim 9, wherein the one pair of stoppers includes:

one pair of insertion protrusions vertically spaced apart from the rotation shaft, and inserted into the stopper receiver.

12. The cleaner according to claim 11, wherein the one pair of insertion protrusions is arranged in a direction perpendicular to a longitudinal direction of any one of the first and second extension pipes.

13. The cleaner according to claim 1, further comprising:

a flexible hose provided between the first and second extension pipes so as to interconnect inner passages of the first and second extension pipes, and configured to have a variable length according to arrangements of the first and second extension pipes.

14. The cleaner according to claim 13, wherein the flexible hose is arranged in a longitudinal direction of each of the first and second extension pipes in the first arrangement.
