A refrigerator comprising: a main body; a storage compartment (20, 30) formed in the main body; a door (21, 22) that opens/closes the storage compartment; a general water tank in which general water supplied from an external water supply source is stored; a mixing tank in which general water supplied from the general water tank is mixed with carbon dioxide (CO 2) so that carbonated water is made and stored; an ice-making machine that makes general ice; a dispenser that provides general water supplied from the general water tank to an outside of the refrigerator and provides carbonated water supplied from the mixing tank to the outside of the refrigerator; an ice-making general water flow path which connects the external water supply source and the ice-making machine so that general water is supplied to the ice-making machine, the ice-making general water flow path not passing through the mixing tank; characterized in that the ice-making machine is further capable of making carbonated ice; the dispenser further provides general ice or carbonated ice made by the ice-making machine to the outside of the refrigerator, the refrigerator further comprises an ice-making carbonated water flow path that connects the mixing tank and the ice-making machine so that carbonated water is supplied to the ice-making machine, a dispensing carbonated water flow path that connects the mixing tank and the dispenser so that carbonated water is supplied to the dispenser, wherein the ice-making carbonated water flow path (240, 340, 440) and the dispensing carbonated water flow path (250, 350, 450) are diverged at a divergence point (280, 370), and a three-way valve (281, 371) is disposed at the divergence point (280, 370) to open and close the ice-making carbonated water flow path (240, 340, 440) and the dispensing carbonated water flow path (250, 350, 450). a main body; a storage compartment (20, 30) formed in the main body; a door (21, 22) that opens/closes the storage compartment; a general water tank in which general water supplied from an external water supply source is stored; a mixing tank in which general water supplied from the general water tank is mixed with carbon dioxide (CO 2) so that carbonated water is made and stored; an ice-making machine that makes general ice; a dispenser that provides general water supplied from the general water tank to an outside of the refrigerator and provides carbonated water supplied from the mixing tank to the outside of the refrigerator; an ice-making general water flow path which connects the external water supply source and the ice-making machine so that general water is supplied to the ice-making machine, the ice-making general water flow path not passing through the mixing tank; characterized in that the ice-making machine is further capable of making carbonated ice; the dispenser further provides general ice or carbonated ice made by the ice-making machine to the outside of the refrigerator, the refrigerator further comprises an ice-making carbonated water flow path that connects the mixing tank and the ice-making machine so that carbonated water is supplied to the ice-making machine, a dispensing carbonated water flow path that connects the mixing tank and the dispenser so that carbonated water is supplied to the dispenser, wherein the ice-making carbonated water flow path (240, 340, 440) and the dispensing carbonated water flow path (250, 350, 450) are diverged at a divergence point (280, 370), and a three-way valve (281, 371) is disposed at the divergence point (280, 370) to open and close the ice-making carbonated water flow path (240, 340, 440) and the dispensing carbonated water flow path (250, 350, 450).
