PURPOSE:To uniform frosting and shorten the operation time for defrosting by such a construction that the feedback cold air from the freezer room to the cooling room is to flow in from the front end of the evaporator to form a gap between the upper division plate and the evaporator, and the feedback cold air from the refrigerating room is to flow into the evaporator through the gap. CONSTITUTION:A freezer suction opening 23 for cold air feedback from the freezing room 14 to the cooling room 18 is formed at the forepart of the lower division plate b. The portion of the undersurface of the upper division plate a facing to the evaporator 17 is depressed upward to form a gap 24 between the evaporator 17 and itself and its fore and rear ends shall be situated in contact with or close to the front and rear parts of the evaporator 17 to hinder direct communication of this gap 24 with the front and rear parts of the cooling room 18. A refrigerator suction opening 25 to communicate the gap 24 with the refrigerating room 13 is installed on the upper division plate a at the later stage of the freezer suction opening 23 and at the back of the contact part of the evaporator 17 with the upper division plate a. Thus feedback cold air from the freezing room and the refrigerating room can be prevented from mixing before the evaporator or frosting at the front end of the evaporator, to realize making frosting uniform. |
