Abstract: A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. In accordance with the present disclosure, the refrigerator includes the trap part in which warm air generated by the defrosting operation is trapped, such that warm air generated by the defrosting operation can be prevented from being introduced into the inner space of the refrigerator through the air passage.

Abstract: A blower configured to circulate cold air inside a body of a refrigerator. The blower includes a casing, an impeller accommodated in the casing, and a support member configured to support the impeller against the casing. The impeller includes a disk-shaped base plate rotatably supported by the support member. The casing includes an inner circumferential surface extending so as to gradually move away from an outer circumference of the base plate toward a rotational direction of the impeller at a predetermined position around the outer circumference of the base plate, and a first case flow path between the inner circumferential surface and the outer circumference. An introduction port configured to introduce the cold air to a second case flow path branched from the first case flow path is formed on the inner circumferential surface of the casing.

Abstract: Disclosed herein is a refrigerator including a cooling cycle mechanism having improved cooling cycle efficiency by more effectively performing heat exchange between a refrigerant discharged from an evaporator and a refrigerant discharged from a condenser. The refrigerator includes a cooling cycle mechanism including a compressor, a condenser, and an evaporator. The refrigerator also includes a first pipe configured including a first heat exchanger and configured to guide the refrigerant from the condenser, to the evaporator. The refrigerator further includes a second pipe including a heat exchanger and configured to guide the refrigerant from the evaporator, to the compressor. The second heat exchanger is adjacent to first heat exchanger and configured to exchange heat with the first heat exchanger. The first heat exchanger and the second heat exchanger are arranged to guide the refrigerant in a same direction.
