Cooling air circulating structure for refrigerator

A cooling air circulating structure for a refrigerator having a freezing compartment, an evaporator chamber, an evaporator disposed in the evaporator chamber for generating a cooling air, a grill panel disposed at a rear portion of the freezing compartment, a refrigerating compartment, and a barrier disposed between the freezing compartment and the refrigerating compartment, the improvements comprising:

• a shroud disposed between the evaporator chamber and the grill panel for distributing cooling air generated in the evaporating chamber into the freezing compartment and the refrigerating compartment, respectively;
• and
• a duct unit disposed in the refrigerating compartment, comprising:
• an upper freshening section duct portion disposed at an upper rear portion of the refrigerating compartment for providing cooling air into a freshening section of the refrigerating compartment and for returning an air circulated in the upper freshening section portion to the evaporator chamber through an air flow path;
• and
• a lower refrigerating section duct portion of which an upper end is integrally connected with a bottom portion of the upper freshening section duct portion for providing cooling air to a refrigerating section of the refrigerating compartment and for returning air circulated in the refrigerating section to the evaporator chamber through the air flow path.
