Refrigerator having centrifugal fan with volute

Abstract

Disclosed is a refrigerator having a centrifugal fan with a volute, which includes a cabinet, an evaporator, a centrifugal fan, and an air supply duct. A cooling chamber located at a lower part and at least one storage compartment located above the cooling chamber are defined in the cabinet; the evaporator is disposed in the cooling chamber and is configured to cool airflow entering the cooling chamber to form cooled airflow; the centrifugal fan includes a volute and an impeller disposed in the volute; and the air supply duct is detachably connected with the volute, communicates with a volute air outlet, and is configured to deliver the cooled airflow into the at least one storage compartment. In the refrigerator of the present invention, the cooling chamber is located at a lower part of the cabinet, so that the cooling chamber occupies a lower space in the cabinet; the storage compartment is located above the cooling chamber, a compressor chamber may be defined behind the cooling chamber, and the storage compartment no longer needs to make room for the compressor chamber, thus guaranteeing the storage volume of the storage compartment. In addition, the air supply duct and the centrifugal fan adopt a split design, which implements modularization, is convenient for disassembly, assembly and transportation, and improves the yield rate.
