Refrigerator

Abstract

In a refrigerator, a cooling air duct for supplying cooling air to an ice making chamber is installed to be exposed from an inner wall face of a refrigerator chamber. Thus, the thickness of the refrigerator main body can be sufficiently secured, and accordingly, temperature of cooling air flowing through the cooling air duct can be prevented from being increased by external air. Also, since the cooling air duct is installed in a receiving space, a generation of frost in the vicinity of the cooling air duct can be prevented, and an increase in a fabrication cost and power consumption when an anti-frost heater is installed can be prevented.
