The aim is to improve the

Embodiments of the present invention will be described below based on the drawings. Reference numeral 1 denotes a refrigerated case main body having an elongated shape, which includes a storage chamber 2 at the top, a cooling chamber 3 directly below the storage chamber, and a machine chamber 4 directly below the cooling chamber. It is composed of. 5A, 5B, 5C, and 5D are four mutually parallel metal front and rear supports that are erected on the square part of the main body and extend from the top to the bottom of the main body, and are used to directly or indirectly support the parts constituting each of the chambers. It supports the following. 6A, 6B, 6C, and 6D are metal decorative plates attached to the front and rear supports and covering the supports. The storage room has a top plate 7 made of resin placed on the top surface, a bottom plate 8 made of resin placed on the bottom side that also serves as a partition plate and serves as the top plate of the cooling room 3, and a square part of this bottom plate erected. Four resin-made front and rear columns 9A, 9B, 9C, and 9D, and three transparent walls 10B, 10C, which are made of multilayer transparent plates and are arranged on three sides and whose ends are fitted and supported by the respective columns. 10D
The product consists of a transparent wall 10A made of a multi-layer transparent plate, a frame 11 with a metal handle 11A fitted to the peripheral edge of this transparent wall, and placed on one side between the front supports 9A and 9B. It is composed of a rotating transparent door 13 that can open and close an opening 12 for access, and a plurality of shelves 14 supported by front and rear columns 9A, 9B, 9C, and 9D, and an annular fluorescent lamp. Become,
A lighting lamp 15 arranged on the bottom plate 8 and a translucent product mounting table 16 covering the lighting lamp 15 on the bottom plate.
It stores. The cooling chamber is composed of a container-shaped heat insulating wall 17 with an open upper surface and the bottom plate 8, and has a plate fin type cooler 18 inside.
It is equipped with an axial flow type blower 19 and a fan case 21 that defines a ventilation hole 20 and partitions the cooling chamber 3 into both high and low pressure regions, and the blower 19 converts the cold air that has undergone heat exchange in the cooler 18 into a forced circulation flow. None, the arrow in FIG. 2 supplies cold air to the storage chamber 2 from the outlet 22 formed at one end edge of the bottom plate 8, and returns the cold air from the storage chamber 2 through the suction port 23 formed at the other end edge of the bottom plate. This forced circulation is repeated to cool the storage chamber 2. The machine room also includes a base plate 24 serving as a bottom surface, and front, rear, left, and right side plates 25A, 25B, 25C, and 25 serving as circumferential surfaces.
D, and the heat insulating wall 17 serving as the upper surface,
A compressor 26 and a condenser 27, which together with the cooler constitute a refrigeration cycle, are housed inside.

The product mounting table is made of translucent resin, and includes an upper wall 30 having an annular protrusion 29 on the peripheral edge to prevent the product 28 from falling, and a top wall 30 extending downward from the peripheral edge of the upper wall to prevent the product 28 from falling. front, rear, left, and right side walls 31A, 31B, 31 that also serve as display sections for displaying product names, prices, etc.
C, 31D are integrally formed, and the left and right side walls 3
1C and 31D are disposed on the bottom plate 8 close to the inside of both the blowout and suction ports 22 and 23,
A lighting room 32 is defined at the bottom of the storage room 2, and left and right side walls 31C, 31D, and left and right transparent walls 10C, 1
Outlet and suction ducts 33 and 34 located directly above the outlet and suction ports 22 and 23 are defined between the outlet and 0D.

According to such a configuration, since the product 28 at the bottom of the storage room 2 can be displayed by floating it from the bottom plate 8 by the product placement table 16, the product 28 at the bottom of the storage room 2 can be displayed by floating it from the bottom plate 8.
8 can be easily seen from the outside, improving the display effect, and when storing and displaying the product 28, the display location of the product 28 is determined on the upper wall 30 of the product mounting table 16. 23
The product mounting table 16 allows normal cold air to be blown out and sucked in without being blocked.
5 to define the illumination chamber 32 at the bottom of the storage room 2, the product placement table 16 itself becomes a shade, and the light from the illumination lamp 15 that passes through can further improve the display effect of the products 28. The lighting effect in the lower part of the storage room 2 where the store lighting is blocked by the lower shelf 14 can be improved, and the product placement table 16 can also be used as an illuminated signboard, and the lighting room 32 itself is insulated. Since it acts as a space, less cold heat is transmitted from the bottom plate 8, which has been made low temperature by the cooler 18, to the product on the product mounting table 16, and overcooling from the bottom of the product 28 can be prevented.
In addition, the left and right side walls 31C and 31D of the product mounting table 16
In order to define the outlet and suction ducts 33 and 34 directly above the outlet and suction ports 22 and 23 by using
The ducts 33 and 34 prevent the cold air flow immediately after the outlet 22 and the cold air flow immediately before the suction port 23 from dispersing, improving the directivity of the cold air flow and improving the rectification and convergence effects, resulting in cooling. The cooling effect of the storage room can be improved by the circulation of airflow, and the separation distance between the outlet and suction ports 22 and 23 on the storage room 2 side by the product placement table 16 is substantially increased to improve the cool air flow in the lower part of the storage room 2. The number of short cycles can be reduced.

As described above, the present invention consists of a storage chamber whose peripheral wall is formed of a transparent wall, and a container-shaped insulating wall with an open top placed directly below the storage chamber, and a cooler and a blower are installed. It consists of a cooling chamber and a bottom plate that partitions the storage and cooling chambers into upper and lower sides and communicates the two chambers with air outlets and suction ports formed on both left and right edges, and cools the storage chamber with forced circulation cold air flow. In the refrigerated case, a lighting lamp is arranged on the bottom plate, and a translucent product mounting table consisting of an upper wall and front, rear, left, and right side walls extending downward from the peripheral edge of the upper wall is placed on both the left and right sides of the refrigerated case. A lighting room is provided at the bottom of the storage room with walls located inside the outlet and suction ports and arranged on the bottom plate so as to cover the lighting lights, and a lighting chamber and both outlet and suction ducts located directly above the outlet and suction ports. The display and illumination effect of the products stored and displayed at the bottom of the storage room can be improved by the product placement stand and the lighting lamp, and the product placement stand and lighting This improves the rectification and convergence of cold air currents, improving the cooling effect of the storage room, and these effects can be obtained with a simple and inexpensive configuration in which the product placement table is placed at the bottom of the storage room. .
