Abstract

Described is an auxiliary cleaning tool assembly of a cleaning apparatus, the auxiliary cleaning tool assembly including a body part connected to a house and having at least one passage, a brush unit rotatably provided on the body part, a nozzle part configured to remove dust attached on the brush unit, and a power transferring part configured to convert an air flow of air passing through the at least one passage of the body part to a rotary force of the brush unit.

Claims

1. A cleaning apparatus comprising:

a cleaner body to generate a suction force; and

an auxiliary cleaning tool assembly comprising;

a body part comprising a hose coupling part, which is selectively connected to a hose to transfer the suction force of the cleaner body, and at least one passage communicating with the hose through the hose coupling part;

a brush unit rotatably provided on the body part;

a nozzle part to draw dust attached on the brush unit; and

a power transferring part to rotate the brush unit by use of an air flow of air passing through the at least one passage of the body part.

2. The cleaning apparatus of claim 1, wherein the power transferring part comprises:

a fan unit rotatable by the air flow of air passing through the at least one passage of the body part; and

a gear unit to transfer a rotary force of the fan unit to the brush unit.

3. The cleaning apparatus of claim 2, wherein the gear unit comprises a worm gear.

4. The cleaning apparatus of claim 2, wherein the gear unit comprises a first gear and a second gear that are engaged with each other, and

a rotary shaft of the fan unit rotates in linkage with the first gear and a rotary shaft of the brush unit rotates in linkage with the second gear.

5. The cleaning apparatus of claim 1, wherein the nozzle part is detachably provided on the body part.

6. The cleaning apparatus of claim 5, wherein the nozzle part comprises a pipe disposed in parallel to the brush unit, wherein the pipe has a plurality of through-holes that are facing toward the brush unit.

7. The cleaning apparatus of claim 6, wherein each of the plurality of through-holes have a larger cross-sectional area as the through-holes are disposed farther from the body part.

8. The cleaning apparatus of claim 5, wherein the nozzle part further comprises a shield part to cover at least one portion of the brush unit.

9. The cleaning apparatus of claim 8, wherein the nozzle part further comprises a rib to reinforce the shield part.

10. The cleaning apparatus of claim 1, further comprising a nozzle assembly rotatably installed on a lower portion of the cleaner body and selectively connected to the hose to draw dust through the nozzle assembly.

11. An auxiliary cleaning tool assembly comprising:

a body part having at least one passage;

a brush unit rotatably provided on the body part;

a nozzle part to draw dust attached on the brush unit; and

a power transferring part to convert an air flow of air passing through the at least one passage of the body part to a rotary force of the brush unit.

12. The auxiliary cleaning tool assembly of claim 11, wherein the power transferring part comprises:

a fan unit to convert an air flow movement of the at least one passage of the body part to a rotary movement; and

a gear unit to transfer the rotary movement of the fan unit to a rotary movement of the brush unit.

13. The auxiliary cleaning tool assembly of claim 12, further comprising a worm gear, wherein a rotary shaft of the fan unit is disposed perpendicular to a rotary shaft of the brush unit, and wherein the rotary shaft of the fan unit rotates in linkage with one shaft of the worm gear and the rotary shaft of the brush unit rotates in linkage with the other shaft of the worm gear.

14. The auxiliary cleaning tool assembly of claim 13, wherein the nozzle part comprises a pipe disposed in parallel to the brush unit, and a bottom surface of the pipe has a plurality of through-holes facing toward the brush unit, and

each of the plurality of through-holes have a larger cross-sectional area as the through-holes are disposed farther from the body part.

15. The auxiliary cleaning tool assembly of claim 11, wherein the brush unit includes a brush and a rotary shaft, and

the brush is formed of microfiber to collect dust using static electricity and is inserted in the rotary shaft.

16. An auxiliary cleaning tool assembly used with a cleaning apparatus, the auxiliary cleaning tool comprising:

a body part having at least one passage;

a brush unit rotatably provided on the body part;

a nozzle part to draw dust attached on the brush unit;

a hose coupling part to transfer an air suction force to the nozzle part;

a fan unit disposed in at least one passage of the body part to convert an air flow movement of the at least one passage of the body part to a rotary movement;

a gear unit to transfer the rotary movement of the fan unit to a rotary movement of the brush unit,

wherein the gear unit comprises a first gear and a second gear that are engaged with each other, and

a rotary shaft of the fan unit rotates in linkage with the first gear and a rotary shaft of the brush unit rotates in linkage with the second gear.

17. The auxiliary cleaning tool assembly of claim 16, wherein the nozzle part comprises:

a pipe to communicate with at least one passage of the body part;

a shield part to cover at least one portion of the brush unit;

and at least one rib extending from the pipe to the shield part, to support a bottom surface of the shield part.

18. The auxiliary cleaning tool assembly of claim 17, wherein a bottom surface of the pipe has a plurality of through-holes facing toward the brush unit, and

each of the plurality of through-holes have a larger cross-sectional area as the through-holes are disposed farther from the body part.

19. The auxiliary cleaning tool assembly of claim 16, wherein the gear unit comprises a worm gear.
