Abstract

A refrigerator is configured to supply cool air to a refrigerating compartment, a freezing compartment, and an ice-making compartment by a single evaporator. A cool air passage for the ice-making compartment for supplying cool air to the ice-making compartment is configured to supply the cool air to an upper space in a cool air passage for the freezing compartment, which supplies cool air to the refrigerating compartment and the freezing compartment, through an upper supply passage. Accordingly, since additional cool air is supplied to the cool air passage for the freezing compartment by using the upper supply passage, sufficient cool air is supplied to the refrigerating compartment and the freezing compartment by the single evaporator.

A refrigerator comprising:

a cabinet having a refrigerating compartment and a freezing compartment, the freezing compartment being located below the refrigerating compartment;
a refrigerating compartment door having an ice-making compartment;
an evaporator located at the freezing compartment and configured to cool air;
and
a freezing compartment side grille fan assembly that is located at a front of the evaporator, the freezing compartment side grille fan assembly comprising:
a freezing fan and an ice-making fan,
a shroud that defines a rear wall surface of the freezing compartment side grille fan assembly and supports the freezing fan and the ice-making fan, and
a grille panel that defines a front wall surface of the freezing compartment side grille fan assembly, the grille panel comprising an insulating member configured to suppress condensation from the ice-making fan,
wherein the freezing compartment side grille fan assembly includes:
a first cool air passage configured to guide air blown by the freezing fan toward the freezing compartment,
a second cool air passage configured to guide air blown by the ice-making fan toward the ice-making compartment, and
a plurality of freezing compartment side cool air outlets defined at the front wall surface of the freezing compartment side grille fan assembly and configured to discharge the air guided along the first cool air passage to the freezing compartment,
wherein the freezing compartment side grille fan assembly further comprises a passage rib that divides the first cool air passage and the second cool air passage from each other, and
wherein the passage rib comprises:
a first circumferential passage rib that extends downward from an upper surface of the freezing compartment side grille fan assembly and is located between the freezing fan and the ice-making fan, the first circumferential passage rib having a round shape surrounding an upper circumference of the ice-making fan, and
a second circumferential passage rib that is located between the first circumferential passage rib and the freezing fan and has a round shape surrounding a lower circumference of the first circumferential passage rib.
