Abstract
A cooling air supply apparatus includes: a blowing fan attached at a rear wall face of a freezing chamber and forcefully circulating air cooled while passing an evaporator of a freezing cycle; a supply passage formed at a barrier partitioning the freezing chamber and a cooling chamber and supplying cooling air ventilated from the blowing fan to the cooling chamber; a rear guide passage branched from the cooling air passage and guiding cooling air backwardly of the cooling chamber; a right guide passage branched from the cooling air supply passage and guiding cooling air rightwardly of the cooling chamber; and a left guide passage branched from the cooling air supply passage, having the same diameter as that of the right guide passage and guiding cooling air leftwardly of the cooling chamber. Since a half of cooling air is guided from the supply passage to the rear guide passage and one-fourth of cooling air is respectively supplied to the right guide passage and the left guide passage, the cooling air distribution in the whole cooling chamber can be uniform. In addition, when a load occurs partially as food, or the like, is received into the freezing chamber, cooling air is concentratively discharged to the portion where the load occurs, so that a cooling operation can be quickly performed.
