Refrigerator

A refrigerator comprising:

• an ice-making unit configured to receive water;
• a cold air generation system configured to circulate a refrigerant and produce cold air through heat exchange between the refrigerant and air in the refrigerator;
• an ice-making pipe disposed proximate to the ice-making unit so that the ice-making unit exchanges heat with the refrigerant flowing in the ice-making pipe, wherein a part of the ice-making pipe is installed within the ice-making unit;
• a refrigerator main body serving as a housing of the refrigerator;
• a door coupled to the refrigerator main body, wherein the ice-making unit is disposed in the door;
• a refrigerant pipe installed in the refrigerator main body, wherein the refrigerant pipe is configured to receive the refrigerant from the cold air generation system, and
• a soft pipe disposed around a hinge shaft that couples the refrigerator main body and the door,
• wherein the soft pipe is a bellows pipe, which is fastened to an end portion of the ice-making pipe and an end portion of the refrigerant pipe by bolts and extends along an up-down axis of the door to withstand twisting deformation around the hinge shaft.
