Abstract

PROBLEM TO BE SOLVED: To prevent temperature rising and drying of food contained in a cold storage chamber by providing air supply ducts for cooling a storage con tainer at ceiling, side, back and bottom surfaces in the chamber, and providing a drainage passage of a U-shaped trap structure at the duct of the ceiling. SOLUTION: Cold air from a cooling chamber 10 is exhausted from a discharge port 16a to a cold air passage 16 by a cooling fan motor 9, and sucked to a suction port 16b. An air supply duct 15 is cooled, and a cold storage chamber 2 is cooled. Accordingly, since an opening 20 and a container 19, chamber 2 are isolated by the duct 15, heats from a gap between the opening 20 and the container 19 and the container 19 can be shut off, and temperature rise of food contained in the chamber 2 can be prevented. Frost is discharged from a ceiling of the duct 15 into the chamber 2 through a drainage port 15a and a drainage passage 17 of a U-shaped trap structure. This condensate is fed into the chamber 2 to easily hold high humidity.
