Claim:
A refrigerator comprising: a cabinet defining a storage space which is opened or closed by a door; an ice making apparatus disposed inside the storage space; a water supply passage extending along the cabinet from a water supply source; and a water supply unit disposed above the ice making apparatus, wherein the water supply unit comprises: a fill tank defining a space into which water supplied through the water supply passage is introduced, the fill tank being configured to have a sectional area greater than a sectional area of the water supply passage; a connection tube connected to an outlet end of the water supply passage to introduce water from the water supply source into the fill tank, the connection tube being located at a position proximate to an edge at which adjacent side walls of the fill tank are connected in order to reduce pressure of the water from the water supply source by causing the water to rotate and swirl along an inner surface of the fill tank; a case body installed in a recess located at an upper surface of the cabinet and having a space to receive the fill tank; a case cover configured to open or close opened top surfaces of the case body and the fill tank; and a guide tube disposed on a bottom surface of the fill tank to extend downward so that the water in the fill tank is supplied into the ice making apparatus after rotating and swirling along the inner surface of the fill tank, wherein the bottom surface of the fill tank is declined from a peripheral portion of the fill tank toward a water discharge hole corresponding to an upper end of the guide tube.
