Patent attributes
A refrigerator having a carbonated water production module integrally provided with a carbon dioxide gas cylinder having carbon dioxide gas stored therein and a carbonated water tank to mix purified water with the carbon dioxide gas to produce carbonated water. The carbonated water production module is mounted to the rear surface of the door, and thus it may be cooled by cool air in the refrigeration compartment and be easy to access, and thereby repair and replacement thereof is facilitated. The dispenser includes a carbonated water discharge channel into which carbonated water from the carbonated water tank is discharged, and a purified water discharge channel into which purified water from the water tank is discharged. Since the purified water discharge channel does not pass through the carbonated water tank, a user is allowed to selectively dispense purified water or carbonated water anytime.
