## Abstract

An apparatus for purifying water comprises: an ice making unit configured to make introduced water into ice cubes, and to store the ice cubes; a cold water unit configured to generate cold water by receiving the ice cubes made by the ice making unit; and a cooling unit configured to supply cold air to the ice making unit. Firstly, since cold water is generated by using ice cubes made by the ice making unit, may be solved the conventional problem that the ice cubes cling to each other due to contact with the cold water. Secondly, the ice making unit, the cold water unit, etc. may be installed so as to be stacked with each other in upper and lower directions, the apparatus for purifying water may have a slim configuration.

## Claims

### Claim 1

An apparatus for purifying water, comprising:
an ice making unit configured to make introduced water into ice cubes, and to store the ice cubes;
a cold water unit configured to generate cold water by receiving the ice cubes made by the ice making unit; and
a cooling unit configured to supply cold air to the ice making unit,
wherein the ice making unit comprises:
an ice maker disposed in a body, the ice maker configured to make water into ice cubes; and
an ice storing unit configured to store the ice cubes discharged from the ice maker, the ice storing unit comprising:
an ice container having first and second openings through which the ice cubes are discharged out; and
an ice transferring portion disposed in the ice container, and configured to transfer the ice cubes to the first opening or the second opening,
wherein the ice storing unit selectively supplies the ice cubes to the cold water unit via the second opening or outside via the first opening.

### Claim 2 (depends on 1)

The apparatus for purifying water of claim 1, wherein the first and second openings are disposed on surfaces of the ice container facing each other.

### Claim 3 (depends on 1)

The apparatus for purifying water of claim 1, wherein the ice transferring portion comprises:
a rotation shaft; and
a transferring screw attached to the rotation shaft, and configured to transfer the ice cubes when the rotation shaft is rotated.

### Claim 4 (depends on 1)

The apparatus for purifying water of claim 1, wherein the first opening is communicated with a discharging unit configured to discharge the ice cubes out of the body, and the second opening serves to guide the ice cubes to the cold water unit.

### Claim 5 (depends on 3)

The apparatus for purifying water of claim 3, wherein a transfer direction of the ice cubes is determined according to a rotation direction of the rotation shaft.

### Claim 6 (depends on 4)

The apparatus for purifying water of claim 4, wherein the discharging unit comprises:
an ice discharge duct configured to guide discharge of the ice cubes; and
an opening/closing member configured to selectively open or close the end of the ice discharge duct in a discharge direction of the ice cubes.

### Claim 7 (depends on 6)

The apparatus for purifying water of claim 6, wherein on an outer circumferential surface of the ice discharge duct, installed is a cold water discharge pipe through which cold water is discharged out from the cold water unit.

### Claim 8 (depends on 1)

The apparatus for purifying water of claim 1, wherein the ice maker, the ice storing unit, and the cold water unit are stacked with each other in upper and lower directions.

### Claim 9 (depends on 8)

The apparatus for purifying water of claim 8, further comprising a hot water unit configured to heat received water to a predetermined temperature, and to store the heated water therein.

### Claim 10 (depends on 8)

The apparatus for purifying water of claim 8, wherein the transferring screw is installed in back and forth directions of the apparatus for purifying water.

### Claim 11 (depends on 1)

The apparatus for purifying water of claim 1, wherein the cooling unit is coupled to an outer surface of the ice maker, so as to freeze the water accommodated in the ice maker by conduction.

### Claim 12 (depends on 1)

The apparatus for purifying water of claim 1, further comprising:
an ice making chamber formed by a heat insulation member; and
a blowing unit configured to blow cold air generated by the cooling unit to the ice making unit,
wherein the ice making unit and the cooling unit are disposed in the ice making chamber.
