Vacuum cleaner

1. A vacuum cleaner comprising:

a main body generating suction force;

a suction head contacting a surface to be cleaned and sucking air and dust from the surface;

a handle pipe for user operation;

a flexible hose connecting the handle pipe and the main body; and

an extension pipe connecting the suction head and the handle pipe,

wherein the handle pipe includes:

a handle pipe body between the extension pipe and the flexible hose with each other; and

a sub-accessory assembly combined integrally with the handle pipe body so as to suck air and dust from the surface as a substitute for the suction head, the sub-accessory assembly further including:

a dusting tool that is extendable, and

a crevice tool that is rotatably attached to the sub-accessory assembly to be rotatable between a connection position, in which the crevice tool is attached to a passageway connected to the handle pipe, and a folding position, in which the crevice tool is not connected to the passageway connected to the handle pipe.

2. The vacuum cleaner according to claim 1 , wherein the dusting tool is provided with a brush and the crevice tool configured to clean a gap.

3. The vacuum cleaner according to claim 2 , wherein the sub-accessory assembly further includes a slide member combined with the handle pipe body so as to be slidable, the dusting tool and the crevice tool being combined with the slide member.

4. The vacuum cleaner according to claim 3 , wherein the dusting tool is combined with the slide member so as to be slidable.

5. The vacuum cleaner according to claim 3 , wherein the slide member is provided to surround the outer circumferential surface of the handle pipe body.

6. The vacuum cleaner according to claim 3 , wherein:

the handle pipe body includes guide grooves formed on the outer circumferential surface thereof to guide movement of the slide member; and

the slide member includes guide protrusions formed on the inner circumferential surface thereof to move along the guide grooves.

7. The vacuum cleaner according to claim 3 , wherein:

the slide member includes a guide hole formed on the outer circumferential surface to guide movement of the dusting tool; and

the dusting tool includes an operating part moving along the guide hole by pressure applied by a user.

8. The vacuum cleaner according to claim 3 , further comprising rotary shafts combining the crevice tool with the slide member so as to be rotatable.

9. The vacuum cleaner according to claim 8 , wherein the rotary shafts are provided on the lower end of the front portion of the slide member.

10. The vacuum cleaner according to claim 3 , wherein the crevice tool is rotatably attached to a slide member which slidably extends the dusting tool.

11. The vacuum cleaner according to claim 10 , wherein the folding position of the crevice tool positions the crevice tool to be located under the slide member.

12. The vacuum cleaner according to claim 10 , wherein the crevice tool is rotatably attached to the slide member using a insertion hole on the slide member, another insertion hole on the crevice tool, and a rotary shaft that extends through the insertion hole on the slide member and the others insertion hole on the crevice tool.

13. A vacuum cleaner comprising:

a main body generating suction force;

a suction head contacting a surface to be cleaned and sucking air and dust from the surface;

an extension pipe combined with the suction head; and

a handle pipe, which is attachable to the extension pipe, including

a handle pipe body,

a slide member combined with the handle pipe body so as to be slidable in the forward and backward direction,

a dusting tool combined with the slide member so as to be slidable in the forward and backward direction and provided with a brush, and

a crevice tool combined with the slide member so as to be rotatable between a folding position under the slide member, in which the crevice tool is not connected to a passageway connected to the handle pipe, and a connection position, in which the crevice tool is attached to the passageway connected to the handle pipe and in which the crevice tool is located in front of the slide member.

14. The vacuum cleaner according to claim 13 , wherein, at the connection position, an inner passage of the crevice tool is connected to an inner passage of the slide member which is attached to the passageway connected to the handle pipe while the crevice tool is rotatably attached.

15. The vacuum cleaner according to claim 13 , wherein the vacuum cleaner is operated in a first cleaning mode using the suction head, a second cleaning mode using the dusting tool, and a third cleaning mode using the crevice tool.

16. The vacuum cleaner according to claim 13 , wherein, in a first cleaning mode using the suction head, the slide member and the dusting tool are moved backward, the crevice tool is disposed at the folding position, and the extension pipe is combined with the handle pipe body.

17. The vacuum cleaner according to claim 13 , wherein, in a second cleaning mode using the dusting tool, the extension pipe is separated from the handle pipe body, the slide member and the dusting tool are moved forward, and the crevice tool is disposed at the folding position.

18. The vacuum cleaner according to claim 13 , wherein, in a third cleaning mode using the crevice tool, the extension pipe is separated from the handle pipe body, the slide member is moved forward, the dusting tool is moved backward, and the crevice tool is disposed at the connection position.
