PURPOSE: A structure for guiding chill flow is provided to increase cooling efficiency by forming a protruding part for guiding chill flow in the front and the upper end of a grille fan in order to smoothly flow a chill from a blower. CONSTITUTION: A compressor(58) and a blower(52) are operated and chilled air is generated by heat exchange of an evaporator(51). The chill is discharged into a grille fan(60) by passing through the gap between a shroud(56) and a blower(52). The discharged air naturally flows in a circumferential direction along a guide protruding part(61) and the chill loss is reduced. One part of the chill is delivered to a freezing chamber through chill exits and the other part is delivered to the chill exit of the cooling chamber through a cooling passage(54). The chill in the cooling and freezing chamber is circulated to the evaporator and the blower through a chill returning passage(55).
