1. A refrigerator comprising:
a main body comprising a refrigerating chamber and a freezing chamber, the refrigerating chamber and the freezing chamber being arranged in a lateral direction;
an evaporator arranged at least partially in a lower portion of the freezing chamber to generate cold air;
a freezing chamber duct provided in the freezing chamber to supply the cold air to the freezing chamber;
a refrigerating chamber duct provided in the refrigerating chamber to supply the cold air to the refrigerating chamber; and
a connection duct provided between the freezing chamber duct and the refrigerating chamber duct and configured to guide cold air from the freezing chamber duct to the refrigerating chamber duct,
wherein the freezing chamber duct includes:
a duct plate forming a front side of the freezing chamber duct, the front side facing a front of the refrigerator;
a duct cover coupled to a rear side of the duct plate, wherein the duct cover includes a damper housing portion protruding rearwardly;
a blower fan provided inside the freezing chamber duct, the blower fan configured to suction the cold air generated by the evaporator into the freezing chamber duct, and to discharge cold air in the freezing chamber duct to at least one of: (i) the freezing chamber, or (ii) the refrigerating chamber duct through the connection duct; and
a damper located in the damper housing portion and provided at one side in a radial direction of the blower fan, to control discharge of the cold air in the freezing chamber duct to the connection duct, wherein the damper housing portion comprises an outlet so that cold air in the freezing chamber duct can flow to the connection duct,
wherein the damper comprises a rotation axis, about which at least part of the damper is configured to move, and the rotation axis is inclined with respect to a vertical direction of the freezing chamber duct, with an upper end of the rotation axis being inclined toward the blower fan, and
wherein the damper housing portion comprises a first side surface having the outlet and formed substantially parallel to the vertical direction of the freezing chamber duct, and a second side surface opposite to the first side surface and inclined with respect to the vertical direction of the freezing chamber duct to correspond the rotation axis.
