Refrigerator with venturi duct between compartments

A refrigerator comprising:

• a main body;
• first and second storage chambers with front sides open in the main body;
• a first inner case defining the first storage chamber;
• a second inner case defining the second storage chamber;
• a cooling path formed between a rear side of the first storage chamber and a rear side of the first inner case;
• an evaporator arranged in the main body to produce cold air;
• a first duct supplying cold air into the first storage chamber and a second duct supplying cold air to the second storage chamber;
• a connecting duct connecting the first duct to the second duct to move the cold air produced from the evaporator to the second duct;
• and
• an auxiliary blower fan arranged adjacent to the smallest area for air in the second storage chamber to flow into the smallest area through a connecting path,
• wherein the first duct is connected to the cooling path and comprises a blower fan provided for cold air in the cooling path to flow into the first duct and the second duct,
• wherein the second duct comprises a connecting port connected to the connecting duct, a discharge port through which the cold air is discharged, a discharge path connecting the connecting port to the discharge port, and the connecting path connecting inside of the second storage chamber to the discharge path,
• wherein the discharge path comprises a smallest area with a smallest cross-section in a vertical direction or in a front-to-back direction, and a connection flow path is arranged to connect an inside of the second storage chamber to the smallest area,
• wherein the discharge path includes a front section between the connecting port and the smallest area, and a rear section between the smallest area and the discharge port, and
• wherein a length of the rear section is formed longer than a length of the front section.
