A cooling display case 1 has a heat insulating bottom wall 2 as a boundary, with an upper part serving as a cooling display room 3 and a lower part serving as a machine room 4. The insulating bottom wall 2 has a rearwardly extending high wall 5 at the rear, and in front thereof a recess 10 that is recessed downward between the front wall 7, the lower wall 8, and the rear wall 9. A cooler 11 of the refrigeration system and a blower 12 for circulating cold air are housed therein, and the upper part thereof is covered with the bottom plate 13 of the cooling display room 3, so that the inside of the recess 10 forms a cooling room 6. The machine room 4 houses a condenser 14, a compressor 17, and a heat radiation blower 15 of the refrigeration system. A front plate 16 is provided in front of the front wall 7 and covers the front side of the machine room 4.
18 is a transparent glass plate that covers the front and top surfaces of the cooling display room 3. Reference numeral 19 is a rear plate that covers the rear surface of the machine room 4 and forms an outside air intake (not shown) and a hot air outlet 21 of the machine room 4. Reference numeral 22 designates side panels made of transparent glass plates that cover the left and right sides of the cooling display room 3. Reference numeral 23 denotes a side plate that covers the left and right sides of the machine room 4, and the right side plate is provided with an air intake port 20, and the left side plate is provided with a hot air outlet (not shown) for the machine room 4. Reference numeral 24 denotes a product display shelf installed in the upper and lower middle part of the cooling display room 3, and is made of a transparent glass plate, and its left and right ends are connected to columns 2 installed at the rear of both sides of the cooling display room 3.
5 is supported by a shelf support 26. 27 is shelf 24
It is an illumination lamp support plate provided on the lower surface of the lamp and also serves as a light reflection plate, and is attached to the shelf 24 or the left and right shelf supports 26. Reference numeral 28 denotes an illumination lamp attached to the illumination lamp support plate 27, which is usually a fluorescent lamp, and has a length that covers approximately the entire width of the shelf 24 together with the illumination lamp support plate 27. An optical path 29 through which reflected light (described later) passes is formed at the rear of the shelf 24. This light path 2
If the shelf 24 is made of a transparent glass plate, it is sufficient to provide a light-transmitting part at the rear end of the shelf 24, and the products on the shelf 24 should not be blocked by the products on the shelf 24. By providing the projecting wall 30, the optical path 29 can be ensured well. Reference numeral 31 designates a transparent glass door forming the back wall of the cooling display room 3, and constitutes a sliding door that moves left and right on a rail 33 placed on a rail mounting portion 32 formed at the upper end of the rear plate 19. . Reference numeral 34 denotes a reflecting plate provided on the back wall of the cooling display room 3, that is, at the upper corner of the door 31, and extending substantially across the entire left and right width of the cooling display room 3, with the reflective surface facing diagonally downward and forward. 35 is a cold air suction port 36 provided between the front end of the bottom plate 13 and the transparent plate 18.
A passage member 38 is provided between the rear end of the bottom plate 13 and the rail 33 and has a cold air outlet 37 formed therein, and its upper surface has a mirror-like reflective surface that effectively reflects light. Reference numeral 39 denotes an evaporation dish placed on the condenser 14, through which defrost water from the cooler 11 is introduced through the drain port 40 and evaporated. The optical path 29 may be formed between the shelf 24 and the door 31.

In this configuration, the cold air in the cooling chamber 6 is discharged upward from the cold air outlet 37 by the blower 12 and
The cooled display room below 4 and the cooled display room above the shelf 24 are cooled by passing between the rear end of the shelf 24 and the door 31, and the air is circulated back to the cooling room 6 from the cold air intake port 36. Furthermore, the light from the illumination lamp 28 is reflected by the lower surface of the support plate 27 and direct light illuminates the cooling display room below the shelf 24, and a portion of this light illuminates the passage member 3.
The reflected light passes through the optical path 29 and is reflected again at the front surface of the reflector plate 34 to illuminate the products on the shelf 24. The front surface of the reflecting plate 34 only needs to be a reflective surface that can effectively reflect light, and may preferably be a mirror-like surface such as a glass mirror or a stainless steel plate, but may also be painted white. Further, the passage member 38 may be made of stainless steel or the like having a mirror-finished upper surface. Also, a cold air discharge port 37 and a cold air suction port 36
A cold air circulation system may be used instead.

(g) Effects of the invention With this invention, the lighting lamps installed on the bottom surface of the shelves can illuminate the cooling display rooms above and below the shelves, so there is no need to install lighting lights for the cooling display rooms above and below the shelves, reducing the number of heating sources. It is effective in achieving this. In addition, since the passage member is used as a reflecting plate, there is no need to provide a special reflecting plate, and the cost can be reduced.
