Reference numeral 1 denotes a duct exclusively for low-temperature containers, which is composed of a molded heat insulating material 12 made of styrofoam or the like and a mounting plate 13 made of plastic or the like. Grooves 14a and 14b are formed in the molded heat insulating material 12 to serve as the refrigerating room suction duct 10 and the duct 11 for low-temperature containers.A refrigerating room suction hole 15 is provided at the tip of the groove 14a, and a passage 14c is provided at the other end. It communicates with the cooling chamber 6 through. Further, both ends of the groove 14b are provided with discharge holes 15 for a low temperature container. A suction hole 17 for a low temperature container is provided. By attaching the molded heat insulating material 12 to the concave portion 19 of the top surface 18 of the refrigerator compartment box, the groove 14 of the molded heat insulating material 12 is removed.
A refrigerating compartment side suction duct 10 and a duct 11 exclusively for low temperature containers are formed between a and 14b and the inner box. In addition, mounting plate 1
3. A low temperature container holding rail 2o is integrally molded in the central part.

れているため取付作業工数が減少する。According to this configuration, during cooling operation, cold air circulates within the layer as indicated by the arrow in FIG. The cold air discharged from the fan 7 passes through the discharge duct 9 and the discharge hole 21. A portion of the cold air enters the refrigerator compartment 4 via the damper thermostat 22, and is divided into a duct 11 exclusively for low-temperature containers, and circulates to the cooler 6 through a suction hole 15 provided on the top of the final refrigerator compartment. . At this time, by installing the molded heat insulating material 12 having the suction hole 15 on the top surface of the refrigerator compartment, the suction hole 15 can be installed at a position relatively far from the discharge hole 21, and the temperature distribution in the refrigerator compartment can be adjusted without causing a short circuit. The discharge hole 16 for the low-temperature container, which has been optimized and molded at the same time, can be installed in the center top of the low-temperature container 22, and the cold air discharged from the discharge hole 16 falls into the low-temperature container 22, thereby reducing temperature variations. The entire low-temperature container 22 can be cooled.Furthermore, since the low-temperature container holding rail 20 is integrally formed with the mounting plate '3, the number of installation work is reduced.

Since the refrigerator compartment side suction duct and the duct dedicated to low temperature containers are formed simultaneously between the inner box and the molded insulation material, the refrigerator compartment side suction hole can be installed relatively far from the discharge hole, preventing short circuits. In addition, the discharge hole for the low-temperature container can be installed in the center top of the low-temperature container, and the cold air discharged from the discharge hole falls into the low-temperature container, ensuring uniform temperature throughout the container. can be cooled. In addition, if a rail for holding the cryogenic container is provided approximately at the center of the mounting plate for fixing the molded insulation material, there is no need to separately form and install a rail member, reducing the number of installation steps and ensuring the holding of the cryogenic container. be able to.
