PROBLEM TO BE SOLVED: To prevent dust and dirt from rising as well by efficiently controlling the temperature of a storage chamber. SOLUTION: A cold storage chamber 2 is provided on one side of a body 1 of a refrigerator and a machine chamber 3 on the other side. A front heat insulated door 5 is opened to move a truck 8 into or out of the cold storage chamber 2. A closure plate 20 is provided at the bottom of the cold storage chamber 2 to close an extra space 25 down from the top surface of a base part 9 of the truck 8. An escape groove 21 is formed on the closure plate 20 to allow the moving of the track 8 in or out. Cool air blown out from an internal storage fan 17 is circulated above a space of the closure plate 20 in the cold storage chamber 2. The circulation of the cool air in the extra space 25 fails and the flow velocity of the cool air increases, so that the cool air efficiently hits a stock stacked on the truck 8 to shorten the cold storage time substantially. This hinders the generation of a turbulence to evenly cool the stock. The cool air ceases to hit the base part 9 and a caster 10 of the truck 8 thereby preventing the flying of dust and dirt adhering thereto. |
