Claims

[Claims for Utility Model Registration] An outer box having a heat insulating structure for storing frozen foods; a first vent hole formed along the inside of one side wall of the outer box and having a plurality of vents communicating with the inside of the outer box;
a second air flow path formed along the inside of the other side wall of the outer box and having a plurality of ventilation holes communicating with the inside of the outer box.
a first duct formed on the inner upper part of the outer box and connecting the first air flow passage and the second air flow passage; a first duct formed on the inner upper part of the outer box; , a second duct connecting the first air flow passage and the second air flow passage and having at least one vent hole communicating with the inside of the outer box; and disposed within the first duct. at least one blower disposed at a vent of the second duct; and at least one blower disposed at a vent of the second duct; and during a thawing operation, the first duct is connected to the first air flow path and the second air flow path. flow path switching means that communicates the second duct with the first air flow path and the second air flow path during cold storage operation; temperature control means for maintaining the temperature of circulating air at a predetermined temperature; humidification means for maintaining the humidity inside the outer box at a predetermined humidity; and a flow direction of the air in the first duct during the thawing operation. The first
and a blower driving means for driving a blower in the duct and driving a blower disposed in the vent of the second duct during the cold storage operation.
