As the shielding block 260 is formed to correspond to the height of the block insertion unit 210 by subtracting the thickness of the stepped portion 244 from the depth of the block insertion unit 210, the chape block is inserted into the block insertion unit 210. As shown in FIG. 8, the upper surface of the shielding block 260 and the upper surface of the heat insulating material 112 form the same plane.

When the inner case 110 is provided on the upper surface of the heat insulator 112 after the above process, the inner case 110 is in a state as shown in FIG. 6 to the weight of food inside the refrigerating chamber 120. Downward deflection is regulated, as well as the cold air speed between the refrigerating chamber 120 and the freezing chamber 130 can be satisfied at the same time.

The scope of the present invention is not limited to the above embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
