２事例のように大きく変化している。However, in the two cases described above, in the former case, the connecting pipe 14 and the first capillary tube 18 between the respective coolers 12 and 13 remain on the inner back surface of the inner box 3 and the heat insulation Although the sealing portion was sealed so as not to form a gap at the contact portion with the partition member 6, there was a fear that cold air might leak and that the connecting pipe 14 might be easily dewed. When the coolers 12 and 13 are apart from each other, a cover is required, which increases the number of parts and the number of mounting steps. In the latter, after the foamed heat insulating material 4 is foamed, the coolers 12 and 13 are arranged from the inside of the inner box 3, and the joints 27 with the pipes 14 and 15 etc. Since welding and gas leak inspection were performed more frequently, the number of welding steps and gas leak inspection steps increased, resulting in an increase in man-hours and an increase in cost. Furthermore, the actual opening 58-2827
No. 2 disclosed in the gazette was for one cooler and one suction pipe in the case of a top freezer. In the present application, the configuration is complicated by a plurality of coolers and a plurality of refrigerant pipes related thereto, and the manufacturing process is greatly changed as in the above two cases.
