After a is raised, it is discharged from the discharge port 42a into the refrigerating chamber 11 while descending the descending passage 29b. Ascending passage 29a
The cold air that has flowed into the ceiling cold air passage 57 from the above through the communication port 29c is discharged into the refrigerating chamber 11 through the discharge port 43a.
Further, since the cooling plate 42 is made of metal, a part of the cold heat of the cold air flowing through the cold air passage 29 is released as cold heat into the refrigerating chamber 11 via the cooling plate 42.

Therefore, the inside of the refrigerating chamber 11 is efficiently and uniformly cooled to, for example, 3 ° C. by the cold heat discharged from the cooling plate 42 and the cool air discharged from the discharge ports 42a and 43a.
The cooling plate 42 may be made of a material having high thermal conductivity, and a ceramic material, a resin material impregnated with a metal filler, or the like may be used.

As shown in FIG. 4, the cool air discharged into the refrigerating compartment 11 passes through the front surface of the placing rack 45 and is discharged to the rear inside the vegetable compartment 12 from the discharge port 38b through the communication passage 49. Then, passing below the storage container 54a, the storage containers 54b, 5
