According to the present invention, an ice manufacturing device includes: a condenser condensing a refrigerant; a compressor compressing the gasified refrigerant; a condenser line transferring the refrigerant compressed from the compressor, to the condenser; a refrigerant line transferring the refrigerant condensed from the condenser, to the compressor; an ice manufacturing part freezing ice manufacturing water; an ice manufacturing water nozzle part placed in the bottom of the ice manufacturing part to discharge the ice manufacturing water to the bottom of the ice manufacturing part; and an ice manufacturing water supply pipe supplying the ice manufacturing water to the ice manufacturing water nozzle part. The ice manufacturing part includes: an internal member placed in an upper part of the ice manufacturing water supply pipe, having the bottom opened, and manufacturing ice while the ice manufacturing water discharged through the ice manufacturing water nozzle part contacts and flows; an external member combined to surround an outer surface of the internal member while being separated away from an outer surface of the internal member; a refrigerant passage part formed to make the refrigerant move along the outer surface of the internal member since the outer surface of the internal member and an inner surface of the external member are combined while being separated away from each other; and a refrigerant entrance part formed in a side and the other side of the external member of the ice manufacturing part. According to the present invention, the refrigerant is directly delivered to the ice manufacturing water while moving along the outer surface of the internal member through the refrigerant passage part in order to reduce cooling time, provide ice for a short time, and save power with the reduction of the cooling time. |
