ABSTRACT:
A fan guard of the freezing chamber in the refrigerator directs the cool air ejected from the cooling fan into the freezing chamber in quantities for shortening the time required for maintaining the optimum ambience of the freezing chamber, economizing the power consumed in the refrigerator and minimizing the cool air which collides against the fan guard and changes the advancing direction thereof to interfere the cooling fan to thereby decrease the noise. For attaining these effects, the fan guard is formed with plural cool air holes and projections for guiding flow of the cool air protrude between the cool air holes toward the cooling fan which circulates the cool air. In another embodiment, a single projection is located on the fan guard and formed between an adjacent pair of the cool air holes and placed along the same axis as the cooling fan.
