## Abstract

The present invention relates to a laundry machine, and more particularly, to an apparatus for treating a laundry, by which a laundry can be treated in a manner of hanging the laundry or the like with a cabinet type body. The present invention includes a cabinet comprising an accommodating space and a mechanism compartment partitioned from the accommodating space by a partition, a steam generator configured to generate steam to be supplied to the accommodating space, and a steam supply unit configured to pass through the partition, the steam supply unit comprising a rotating nozzle to supply steam into the accommodating space.

## Claims

### Claim 1

A laundry machine comprising:
a cabinet comprising a space configured to statically accommodate laundry and a mechanism compartment partitioned from the space by a partition;
a steam generator provided in the mechanism compartment to generate steam to be supplied to the space;
a steam supply unit provided in the cabinet to pass through the partition, the steam supply unit comprising:
a rotating nozzle to supply steam into the space;
a support shaft configured to rotatably support the nozzle, wherein the support shaft includes a hollow pipe; and
a steam hose configured to connect the nozzle to the steam generator, wherein the steam hose is configured to pass through the partition.

### Claim 2 (depends on 1)

The laundry machine of claim 1, wherein the nozzle comprises a plurality of sub-arms.

### Claim 3 (depends on 2)

The laundry machine of claim 2, wherein the each sub arm comprises a plurality of steam outlets.

### Claim 4 (depends on 3)

The laundry machine of claim 3, wherein at least one of the steam outlets is provided to supply the steam in a tangential direction with respect to a rotating axis of the nozzle so as to rotate the nozzle.

### Claim 5 (depends on 4)

The laundry machine of claim 4, wherein the sub-arms are upwardly slanted in a radial direction.

### Claim 6 (depends on 1)

The laundry machine of claim 1, wherein the steam hose connected to the support shaft by being inserted into the support shaft.

### Claim 7 (depends on 6)

The laundry machine of claim 6, wherein the steam hose is formed as a flexible hose.

### Claim 8 (depends on 1)

The laundry machine of claim 1, wherein the support shaft is configured to pass through the partition.

### Claim 9 (depends on 1)

The laundry machine of claim 1, wherein the steam supply unit further comprises a rotation pipe configured to rotate inside the support shaft as one body with the nozzle.

### Claim 10 (depends on 9)

The laundry machine of claim 9, further comprising an actuating device configured to generate actuating force to rotate the rotation pipe, the actuating device being installed in the mechanism compartment.

### Claim 11 (depends on 9)

The laundry machine of claim 9, further comprising:
a main door for selectively opening or closing the space; and
a sub-door provided inside the cabinet for selectively opening or closing the mechanism compartment when the main door is open.

### Claim 12 (depends on 11)

The laundry machine of claim 11, wherein the steam supply unit further comprises a flexible steam hose configured to form a steam path between the steam generator and the support shaft.

### Claim 13 (depends on 12)

The laundry machine of claim 12, wherein the steam supply unit further comprises a rotation pipe configured to rotate inside the support shaft as one body with the nozzle.

### Claim 14 (depends on 13)

The laundry machine of claim 13, wherein the steam hose is configured to pass through the partition and to be connected to the support shaft in the space.

### Claim 15 (depends on 13)

The laundry machine of claim 13, wherein the support shaft is configured to pass through the partition and to be connected to the steam hose in the mechanism compartment.

### Claim 16 (depends on 13)

The laundry machine of claim 13, wherein the nozzle has a parabola shape portion, a plurality of steam outlets being formed at the parabola shape portion.
