I can guide you.

  By pulling out the intermediate duct 41 toward the front side and removing the duct 41 from the shelf plate 25 in the middle of the upper and lower portions, the display room 3 is not divided into the low-temperature area A1 and the high-temperature area A2, and the entire display room 3 has the same temperature. Can be cooled. In this case, it is necessary to store the removed intermediate duct 41. If the intermediate duct 41 that is not used is stored in the backyard or the like of the store, the intermediate duct 41 may be lost, and it is necessary to go to the backyard when the product is changed. Therefore, in the showcase of the present embodiment, a duct storage section 65 for storing the intermediate duct 41 in the showcase is provided below the lowermost shelf 25B.

  Duct storage rails 66 on which the left and right ends of the duct main body 42 of the intermediate duct 41 are mounted project inward from each of a pair of shelf brackets 26B (26) supporting the lowermost shelf board 25B. I have. The middle duct 41 when not in use is inserted into the duct 41 from the front side of the display room 3 between the lower surface of the shelf board 25B and the upper surfaces of the pair of duct storage rails 66, so that the left and right ends of the duct main body 42 are inserted. Can be stored in the duct storage section 65 while being supported by the pair of duct storage rails 66. In this embodiment, in order to facilitate removal of the intermediate duct 41 stored in the duct storage section 65, the front end of the intermediate duct 41 in the stored state is positioned slightly forward of the front end of the shelf 25. It is stored. At this time, since the damper portion 43 interferes with the front cover wall 36 of the cold air guide 34, a rectangular box-shaped escape recess 67 having a long left and right opening with a front opening is formed in the front cover wall 36. The intermediate duct 41 is accommodated in the duct accommodating portion 65 in a state where the rear end of the damper portion 43 is in contact with the inner wall surface of the escape recess 67.

  As described above, when the duct storage rails 66 are provided to protrude inward and the duct storage portions 65 are provided on each of the pair of shelf brackets 26B that support the lowermost shelf plate 25B, the inside of the display room 3 has a low temperature. When the showcase is used without being divided into the area A1 and the high-temperature area A2, the intermediate duct 41 can be placed and stored on the duct storage rail 66. Accordingly, it is not necessary to store the intermediate duct 41 when it is not used in a backyard or the like. When the intermediate duct 41 is used, the intermediate duct 41 is inserted into the damper opening 46 without any trouble, and is mounted. Is divided into a low-temperature area A1 and a high-temperature area A2, and can be used as a two-temperature type showcase.

  As described above, in the showcase according to the present embodiment, the storage room 52 for storing the shelf accessories 51 is provided at the corner C of the inner case 2 defined by the back plate 11 and the bottom plate 13. . According to such a showcase, since the storage room 52 is arranged at the lower back portion of the display room 3 that is difficult for a young child to reach, it is possible to effectively eliminate mischief of the storage room 52 by the young child. it can. Further, since the corner C is hardly noticeable to the purchaser and is not originally a product display place, the storage room 52 is provided in the corner C so that the storage room 52 can be easily stored without moving the product. The shelf accessories 51 can be stored, or the shelf accessories 51 can be taken out of the storage room 52.

  In the above embodiment, the cold air guide 34 only needs to include at least the guide wall 35, and the front cover wall 36 and the side cover wall 37 can be omitted. The lowermost shelf 25B can be formed to have a smaller front-to-rear dimension than the other shelf 25A, so that the front end positions of the respective shelf 25 are aligned. The fixing tool 58 may be a fastener such as a snap lock or a bolt and a nut other than the latch type fixing tool. The present invention can be applied to a refrigerated or frozen open showcase and a refrigerated or frozen closed showcase, in addition to the two-temperature open showcase shown in the above embodiment.
