PURPOSE: An airtight room of a refrigerator is provided to maximize thermal efficiency of a case as a heat exchange unit is positioned at the circumference of the case to circulate cold air. CONSTITUTION: An airtight room(10) of a refrigerator comprises a case(100), a storing case(200), a sealing unit, and a heat exchanger(110). The case is placed in the chamber of the refrigerator. The storing case is placed inside the case. The sealing unit seals the inside of the storing case. The heat exchanger is formed on the circumference of the case, and heat-exchanges cold air discharged to the chamber. The heat exchanger comprises a shelf where objects are placed. The shelf comprises a placing member for the objects formed into cylindrical shapes. The shelf is connected to the upper part of the case by a support unit. The support unit is placed on the shelf, and separately supports the shelf from the upper surface of the case. The support unit comprises a support rag(132) forming a hook and a stopping hole(135). |
