The mermaid case 4 is hygienic, and the synthetic resins such as impact-resistant styrol resins or ABS resins, which are excellent in cold resistance and durability, are not scratched and contaminated by foods as they are taken out and put into foods. It is made so that the front surface is opened and is installed on the inner wall of the cabinet (2).

In addition, a barrier 6 is installed at one side of the inner wall of the mermaid case 4 so that the inside of the refrigerator may be divided into a freezer compartment F and a refrigerator compartment R, and the barrier 6 may be detachably fitted. Both side and rear sides are formed with insertion grooves 7 into which both end and rear ends of the barrier are inserted.

The barrier 6 is formed in the shape of a panel so that both side ends and rear ends are installed to be inserted into or removed from the insertion groove 7, so that the barrier 6 can secure the contents of the refrigerator and manually defrost the freezer compartment. Make it happen.

In addition, the refrigerator according to the prior art compresses the refrigerant and converts the refrigerant into a high temperature and high pressure steam state, and the refrigerant 10 becomes a high temperature and high pressure steam state through the compressor 10 by exchanging heat with ambient air to cool the refrigerant. It further comprises a condenser 20 for condensing in a high pressure liquid state, and an expansion mechanism (not shown) for reducing the refrigerant that has become a high pressure liquid state through the condenser 20 and the like.
