Abstract: A refrigerator includes a first storage space, a second storage space, a passage duct assembly disposed behind the second storage space and including a cold air passage, a grille fan assembly disposed behind the first storage space and provided with a fan configured to blow cold air, a supply duct assembly configured to supply cold air blown from the grille fan assembly to the passage duct assembly, and a passage opening/closing module configured to selectively block the cold air supplied to the supply duct assembly. The passage opening/closing module includes a damper having a damper through-hole and a damper door configured to open and close the damper through-hole, and a damper cover configured to surround at least a portion of the damper. The damper cover includes an anti-freezing passage through which a portion of the cold air blown from the grille fan assembly is discharged to the supply duct assembly.

Abstract: Proposed is a refrigerator which includes a cabinet, an evaporator, a freezer compartment grille assembly, a refrigerating compartment grille assembly, a refrigerating compartment door, and a cold air duct for door cooling. Particularly, the cold air duct for door cooling is located to be as apart as possible from a hot line or an outer casing so as to reduce heat loss and power consumption due to the heat loss.

Abstract: A refrigerator includes an inner case including (i) a refrigerating case that defines a refrigerator compartment and (ii) a freezing case that defines a freezer compartment, an outer case disposed outside the inner case, a connection duct disposed between the inner case and the outer case, and a refrigerator compartment cold air supply duct that is detachably coupled to a rear inner surface of the refrigerating case and in fluid communication with the connection duct. The connection duct and the refrigerator compartment cold air supply duct are in communication on a rear surface of the refrigerating case with the refrigerating case interposed therebetween, thereby reducing the area occupied by the refrigerator compartment cold air supply duct disposed in the rear inner surface of the refrigerator compartment.

Abstract: Proposed is a refrigerator, wherein a cool air flow path for an ice making compartment and a cool air flow path for a freezing compartment are integrally formed on opposed surfaces between a shroud and a grill fan, and a freezing fan and an ice making fan are collectively installed at the shroud. Therefore, the cool air flow path for the ice making compartment and the cool air flow path for the freezing compartment are defined between the grill fan and the shroud by the operation of intimately coupling the shroud to the grill fan.

Abstract: Disclosed is a refrigerator including a main body forming a refrigerating chamber and a freezing chamber each including a temperature sensor, a cooling unit having a compressor and an evaporator accommodated inside the main body and driven to circulate a refrigerant in the compressor and the evaporator to generate cold air around the evaporator, a fan positioned inside the main body to supply the cold air to the freezing chamber, a damper positioned between the freezing chamber and the refrigerating chamber and opened and closed to allow the freezing chamber and the refrigerating chamber to selectively communicate with each other, and a controller controlling the damper for a predetermined damper opening time when a temperature of the freezing chamber reaches a freezing satisfaction temperature according to driving of the cooling unit. A temperature change of the refrigerating chamber over time may be reduced and power consumption may be improved.
