An air-cooled refrigerator supplying air through a centrifugal fan, comprising a bottom liner, an air duct back plate, and the centrifugal fan. A cooling chamber and a storage space are defined in the bottom liner; the air duct back plate is provided in the-front of a back wall of the bottom liner, and defines an air supply duct with the back wall of the bottom liner; the centrifugal fan comprises a volute and an impeller; the volute is arranged obliquely upwards from front to back at the back of the cooling chamber, and a fan cavity and a gradually widened exhaust cavity are defined in the volute; the fan cavity is formed into a continuous spiral; the gradually widened exhaust cavity is gradually widen backwards from the fan cavity; the impeller is provided in the fan cavity; and the inner wall face of the fan cavity is continuous and smooth.

An appliance ice-making compartment includes a housing which defines an inlet aperture and an outlet aperture. A first ice tray is disposed at a first height within the housing. A second ice tray is disposed at a second height within the housing where the first height is closer to a top of the housing compared to the second height. The second ice tray is closer to the inlet aperture compared to the first ice tray. An inlet duct is in fluid communication with the inlet aperture and configured to direct air toward the first ice tray and the second ice tray.

A refrigerator includes a blower fan assembly having a cold air introduction hole configured to be open toward a storage compartment, and the blower fan assembly is located behind the front surface of an evaporator. Due to the structure of the refrigerator, cold air passing through the evaporator may efficiently flow to the cold air introduction hole of the blower fan assembly, and the flow resistance of the cold air may be reduced, so consumption efficiency may be improved.

An air-cooled refrigerator comprises a bottom liner, a fan bottom shell, an air duct cover plate, and fan blades. A cooling chamber and a storage space are defined in the bottom liner. The fan bottom shell is arranged at a rear portion of the cooling chamber. The air duct cover plate comprises a back plate portion and a fan upper cover. The back plate portion is disposed in front of a rear wall of the bottom liner. The fan upper cover obliquely extends downward from a lower end of the back plate portion into the cooling chamber, covers the fan bottom shell and is fastened thereto. The back plate portion and the fan upper cover are integrally formed. The fan blades are arranged in a fan cavity, and enable formation of a refrigeration airflow discharged from the cooling chamber to an air supply duct.

A refrigerator include: an inner case having a storage chamber; a thermoelectric module including a thermoelectric element and a cooling sink; a fan configured to circulate air, to the storage chamber; a fan cover configured to cover the fan and having an upper discharge hole, a lower discharge hole, and an inner suction hole formed between the upper discharge hole and the lower discharge hole; a first receiving member disposed in the storage chamber; and a second receiving member disposed over the first receiving member to be spaced apart from the first receiving member. At least a portion of each of the inner suction hole and the lower discharge hole faces a portion between the first receiving member and the second receiving member, and at least a portion of the upper discharge hole faces a portion between a top surface of the storage chamber and the second receiving member.

A refrigerator is provided. The refrigerator includes a body having a storage compartment, an ice making device, and an ice bucket to store the generated ice. The ice bucket includes an ice bucket body, an ice storage space inside the ice bucket body, and a spacing member to allow ice to be spaced apart from the ice bucket body toward the ice storage space to secure a flow path of cool air, so that the cool air smoothly flows inside the ice bucket body. A full-ice detecting sensor having an emitter and a receiver to receive optical signals is provided. A control unit determines a full-ice status by receiving an output value of signals received from the full-ice detecting sensor.

A refrigerator include: an inner case having a storage chamber; a thermoelectric module including a thermoelectric element and a cooling sink; a fan configured to circulate air to the storage chamber; a fan cover configured to cover the fan and having an upper discharge hole, a lower discharge hole, and an inner suction hole formed between the upper discharge hole and the lower discharge hole; a first receiving member disposed in the storage chamber; and a second receiving member disposed over the first receiving member to be spaced apart from the first receiving member. At least a portion of each of the inner suction hole and the lower discharge hole faces a portion between the first receiving member and the second receiving member, and at least a portion of the upper discharge hole faces a portion between a top surface of the storage chamber and the second receiving member.

A refrigerator includes a main body including an inner case and an outer case, a storage compartment defined by the inner case, a door configured to open and close the storage compartment, an ice making chamber disposed on a rear surface of the door, a fan configured to supply cold air to the storage compartment and the ice making chamber, and a guide passage formed by being recessed into the inner case to guide cold air supplied by the fan to the ice making chamber. The inner case includes an upper wall, and the guide passage is formed by being recessed into the upper wall of the inner case to be exposed to the storage compartment.

A refrigeration system including a storage chamber configured to store a product at a predetermined temperature. The storage chamber is defined by an inner wall. The inner wall at least partially defines an air plenum. The inner wall includes an opening wall surface, a floor surface, a rear wall surface and a ceiling wall surface. The system also includes a refrigerant circuit including a compressor, a condenser, a condenser fan, an evaporator and an evaporator fan arranged and disposed in an operable configuration to provide refrigeration to the storage chamber. The air plenum includes a conduit arranged and disposed to convey air from an air inlet across the evaporator and into a discharge chamber and out an air outlet. The air outlet is configured to discharge cooled air in a direction toward the opening wall surface.

A refrigerator includes a cabinet, an evaporator, an evaporator cover module, and a cold air supply module configured to communicate with the evaporator cover module. The evaporator cover module includes a rear plate that has a planar shape and that defines the surface of the storage space, a first insulation member located at a rear surface of the rear plate, and a second insulation member spaced apart from the first insulation member and located at a front surface of the inner case. The first insulation member and the second insulation member define a heat-exchange space configured to accommodate the evaporator between the first insulation member and the second insulation member.
