Abstract

A laundry treating apparatus is disclosed. The laundry treating apparatus includes a treating chamber to accommodate laundry, a heating part to supply at least one of hot air and steam to the treating chamber, a hanger bar arranged in the treating chamber, a driving part provided on an outside of the treating chamber to generate a rotational force, a power transmitting part transmitting the rotational force of the driving part, and a power converting part converting the rotational force transmitted by the power transmitting part to reciprocate the hanger bar.

First claim

The invention claimed is:

1. A laundry treating apparatus comprising:
a treating chamber;
a heating part to supply at least one of hot air or steam to the treating chamber;
a hanger bar in the treating chamber, the hanger bar including a slot;
a driving part on an outside of the treating chamber to generate a rotational force; and
a power converting part to move the hanger bar by converting the rotational force transmitted by the driving part,
wherein the power converting part comprises:
a shaft connected portion connected to a shaft of the driving part;
a rotation arm extended from the shaft connected portion in an orthogonal direction with respect to the shaft; and
a slot connected portion, rotatable with respect to the shaft, projected from an end of the rotation arm and in the slot of the hanger bar, and

wherein a length of the slot is greater than or equal to a radius of a rotational locus formed by the slot connected portion and less than a diameter of a rotational locus formed by the slot connected portion.

2. The laundry treating apparatus as claimed in claim 1 , wherein the slot is orthogonal to a longitudinal direction of the hanger bar.

3. The laundry treating apparatus as claimed in claim 1 , wherein the slot is parallel with a longitudinal direction of the hanger bar.

4. A laundry treating apparatus comprising:
a treating chamber to accommodate laundry;
a heating part to supply at least one of hot air and steam to the treating chamber;
a hanger bar in the treating chamber, the hanger bar having a slot;
a driving part on an outside of the treating chamber to generate a rotational force;
a power transmitting part transmitting the rotational force of the driving part; and
a power converting part converting the rotational force transmitted by the power transmitting part to reciprocate the hanger bar,
wherein the power transmitting part comprises:
a driving pulley rotated by the driving part;
a driven pulley in communication with the driving pulley;
a belt connecting the driving pulley with the driven pulley; and
a shaft rotated by the driven pulley,

wherein the power converting part comprises:
a shaft connected portion connected to the shaft;
a rotation arm extended from the shaft connected portion in an orthogonal direction with respect to the shaft; and
a slot connected portion projected from an end of the rotation arm and in a slot of the hanger bar, and

wherein a length of the slot is greater than or equal to a radius of a rotational locus formed by the slot connected portion and less than a diameter of a rotational locus formed by the slot connected portion.

5. The laundry treating apparatus as claimed in claim 1 , further comprising a bearing part having a first bearing to support the shaft.

6. The laundry treating apparatus as claimed in claim 1 , wherein a diameter of the driven pulley is larger than a diameter of the driving pulley.

7. The laundry treating apparatus as claimed in claim 1 , wherein the slot comprises a drain hole.

8. The laundry treating apparatus as claimed in claim 1 , wherein the slot is oriented in an orthogonal direction with respect to a motion of the hanger bar.

9. The laundry treating apparatus as claimed in claim 5 , wherein the slot connected portion comprises:
a protrusion from the rotation arm; and
a suspending member circumscribed by the protrusion.

10. The laundry treating apparatus as claimed in claim 9 , wherein the suspending member includes a flexible material.

11. The laundry treating apparatus as claimed in claim 9 , wherein the slot connected portion comprises a second bearing between the protrusion and the suspending member.

12. The laundry treating apparatus as claimed in claim 11 , wherein the second bearing is an oilless bearing.

13. The laundry treating apparatus as claimed in claim 1 , further comprising:
a supporter supporting the hanger bar, the supporter comprising a flexible member.

14. The laundry treating apparatus as claimed in claim 13 , wherein the supporter limits a forward/rearward motion of the hanger bar.

15. The laundry treating apparatus as claimed in claim 1 , wherein the slot is orthogonal to a longitudinal direction of the hanger bar.

16. The laundry treating apparatus as claimed claim 1 , wherein the slot is parallel with a longitudinal direction of the hanger bar.

17. The laundry treating apparatus as claimed in claim 1 , further comprising:
a sensing part sensing a position of the hanger bar.

18. The laundry treating apparatus as claimed in claim 17 , further comprising a control part receiving a signal from the sensing part,
wherein the control part moves the hanger bar to a predetermined initial position after an operation of the heating part is completed.

19. The laundry treating apparatus as claimed in claim 17 , wherein the sensing part comprises:
a magnetic substance; and
a magnetic force sensor capable of sensing a magnetic force of the magnetic substance.

20. The laundry treating apparatus as claimed in claim 19 , further comprising a bearing housing supporting the shaft,
wherein one of the driven pulley and the bearing housing includes the magnetic substance, and the other of the driven pulley and the bearing housing includes the magnetic force sensor.

21. The laundry treating apparatus as claimed in claim 20 , wherein an upper position determining part is in an outer circumferential surface of an upper end of the shaft in which the magnetic force sensor is able to sense the magnetic substance if the driven pulley is fastened to the shaft, and
wherein a lower position determining part is in a lower circumferential surface of a lower end of the shaft in which the slot connected portion is able to be inserted in the slot if the driven pulley is fastened to the upper position determining part.

22. The laundry treating apparatus as claimed in claim 21 , wherein the upper position determining part and the lower position determining part are cut-away surfaces in the outer circumferential surface of the shaft.

23. A laundry treating apparatus comprising:
a treating chamber;
a heating part to supply at least one of hot air or steam to the treating chamber;
a hanger bar in the treating chamber, the hanger bar having a slot;
a driving part on an outside of the treating chamber to generate a rotational force;
a power converting part to move the hanger bar by converting the rotational force transmitted by the driving part; and
a power transmitting part transmitting the rotational force transmitted by the driving part to the power converting part, the power transmitting part comprising:
a driving gear rotated by the driving part;
a driven gear in communication with the driving gear; and
a shaft rotated by the driven gear,

wherein the power converting part comprises;
a shaft connected portion connected to the shaft;
a rotation arm extended from the shaft connected portion in an orthogonal direction with respect to the shaft; and
a slot connected portion rotatable with respect to the shaft, projected from an end of the rotation arm, and in the slot of the hanger bar, and

wherein a length of the slot is greater than or equal to a radius of a rotational locus formed by the slot connected portion and less than a diameter of a rotational locus formed by the slot connected portion.
