In the prior art, since the cooling capacity is transferred from the inner wall of the cooling compartment 10 (i.e., the liner 11) to the middle position of the cooling compartment 10, the size of the cooling compartment 10 is generally large, and the large size inevitably causes uneven cooling capacity in the cooling compartment 10. In particular, the more cold is present at a position closer to the inner wall of the refrigerated compartment 10.

In addition, since the refrigerating compartment 10 is disposed with the opening upward, and the upper side of the whole refrigerating compartment 10 is open, the cooling capacity of the opening of the refrigerating compartment 10 is seriously dissipated outwards, and the difference between the cooling capacity of the position of the refrigerating compartment 10 close to the opening and the cooling capacity of the refrigerating compartment 10 close to the bottom is also caused. In particular, the more the cooling capacity is in the region closer to the bottom of the refrigerated compartment 10, the less the cooling capacity is in the open position of the space refrigerated compartment 10.
