A refrigerator comprises a freezing compartment having an outlet, through which cold air is discharged, on a rear surface thereof, a first ice maker being mounted on an upper surface of the freezing compartment, and a second ice maker being mounted on the upper surface of the freezing compartment in a way that the second ice maker is spaced from the first ice maker, and further comprises an air guide comprising a first air guide outlet that is disposed to overlap the outlet at least partially and guides a portion of cold air discharged from the outlet to the first ice maker, a second air guide outlet that guides a portion of cold air discharged from the outlet to the second ice maker, and a third air guide outlet that guides a portion of cold air discharged from the outlet between the first ice maker and the second ice maker.

Refrigerator

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.

A refrigerator includes a cabinet, a first storage chamber and a second storage chamber, and a grille fan assembly partitioning the first storage chamber into a space receiving an evaporator, and a grille fan assembly including a grille panel, a shroud supporting a first fan and a second fan, a heat insulating member provided between the grille panel and the shroud and defining a first flow path configured to supply cold air blown by the first fan to the first storage chamber and a second flow path configured to supply cold air blown by the second fan to the second storage chamber, and a duct connector provided at a position corresponding to the second fan between the shroud and the heat insulating member and connected to the second flow path part to define an independent flow path.

A refrigerator 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.

A refrigerator includes: an evaporator provided in a storage space and configured to supply cold air to the storage space, a duct assembly provided above the evaporator and configured to guide the cold air supplied to the storage space, a door supply duct coupled to the duct assembly and configured to guide a part of the cold air flowing through the duct assembly to a door, and a fan motor assembly coupled to a lower end of the duct assembly and configured to suction air cooled by the evaporator and blow the suctioned air into the duct assembly. The duct assembly defines a first passage and a second passage that are spaced apart from each other, where the second passage includes a main passage configured to supply the cold air to the storage space and a sub-passage branched from the main passage and coupled to the door supply duct.

A refrigerator includes a cool air flow path for an ice making compartment and a cool air flow path for a freezing compartment. The cool air flow paths are integrally formed on opposed surfaces between a shroud and a grill fan. A freezing fan and an ice making fan are collectively installed at the shroud. 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.

A refrigerator is proposed. Due to a first heater provided in a damper assembly, a damper assembly or the connection portion of the damper assembly with a supply duct is prevented from freezing, and due to a second heater provided in the supply duct, the connection portion of the supply duct with the damper assembly or the inside of the supply duct is prevented from freezing.

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.

Refrigerator and control method therefor

A refrigerator may include: a refrigerator compartment, a convertible compartment, an evaporator disposed in the convertible compartment; and a grill pan assembly forming a space where the evaporator is disposed by dividing the inside of the convertible compartment. The grill pan assembly may include an insulating member, a convertible compartment fan, a refrigerator compartment fan, and an opening device formed at the insulating member from the convertible compartment channel to the refrigerator compartment channel.

A duct structure of a refrigerator equipped with a door provided with a container space separated from an internal space of the refrigerator comprises: a multi-duct which is provided in a rear space in the internal space of the refrigerator and which discharges cool air into the internal space of the refrigerator while allowing air to flow upward; a connecting outlet which is provided in an upper end of the multi-duct; a connecting duct which communicates with the connecting outlet and which is extended in a front-rear direction; a front duct which is connected to a front end of the connecting duct and which is extended in a left-right direction; and a nozzle unit which is provided in a lower portion of the front duct and which discharges cool air into the container space of door.

A method, which is for controlling a temperature of a refrigerating compartment, includes cooling the refrigerating compartment, cooling the freezing compartment, determining a temperature of the refrigerating compartment, and based on the temperature of the refrigerating compartment, controlling the refrigerating compartment to a constant temperature range by controlling opening and closing of first and second passages of a three-way valve of the refrigerator to alternate cooling the refrigerating compartment and cooling the freezing compartment.
