REFRIGERATOR

摘要

Disclosed herein is a refrigerator configured to delay increase in temperature of a storage compartment by lowering temperature of air that is heated by a defrost heater. A refrigerator includes a defrost heater, a lower cool air duct including a first flow path configured to guide cool air generated by the evaporator to be supplied to the storage compartment and an upper cool air duct disposed in an upper side of the lower cool air duct and provided with a second flow path configured to guide cool air generated by the evaporator to be supplied to the storage compartment. A cool pack in which cold storage material is filled stores cold storage energy from cool air that is delivered to the second flow path to decrease a temperature of air passing via the second flow path, so that increase of an internal temperature of the storage compartment is delayed.

主权项

1. A refrigerator comprising:
a body; a storage compartment provided inside of the body to have an opened front surface; an evaporator provided in a rear side of the storage compartment to generate cool air; a defrost heater provided in a lower side of the evaporator; a lower cool air duct having a first flow path configured to guide cool air generated by the evaporator to be supplied to the storage compartment; and an upper cool air duct disposed in an upper side of the lower cool air duct, the upper cool air duct including a second flow path configured to guide cool air generated by the evaporator to be supplied to the storage compartment, wherein a cool pack in which storage material is filled stores cold storage energy from cool air that is delivered to the second flow path of the upper cool air duct to decrease a temperature of air passing via the second flow path of the upper cool air duct while the defrost heater is being operated, so that increase in an internal temperature of the storage compartment due to heat from the defrost heater is delayed.
