The visibility of the commodity V at the bottom is improved, and the commodity V is easily taken out.

Further, the height from the middle display surface (high portion 6B) to the uppermost display surface (shelf 91; high portion 6B when shelf 91 is not installed) is 300 mm or more from the installation surface.
Similarly, when the open showcase 1 is installed on the cashier counter C, the height from the floor to the uppermost display surface (the shelf 91 or the higher portion 6B) is in the range of 1100 mm to 1700 mm. And height. Thereby, the height of the uppermost display surface is in the range from the abdomen to the face of the customer, the visibility of the uppermost product V is improved, and the product V can be easily taken out.

Further, as described above, the height of the machine room 14 is made lower at the front part and higher at the rear part by the step shape of the heat insulating wall 4, so that the lowermost display surface (lower part 6A) is set lower. Meanwhile, it is possible to install a device having a large size such as the compressor 63 or the condenser 64 at the rear part in the machine room 14.

On the other hand, when the condenser blower 69 is operated, the outside air is sucked from the intake port 2 A of the rear panel 2, is passed through the condenser 64, and is blown to the evaporation tray 68 in front. As a result, the drain water in the evaporating dish 68 is evaporated. Some of the warm air that has been heated by the air cooling of the condenser 64 and the warm air generated by the compressor 63 flows out to the outside through the exhaust port 3A around the unit base 3, but the rest is cut out at the rear portions on both sides of the unit base 3. 3B, a part of the remainder flows out of the notch 3B to the outside, and the other part flows into the exhaust duct 86 of the side plates 7, 7 (FIG. 10).

The warm air flowing out of the notch 3B flows to the outer surface of the outer plate 82 below the side plate 7 to warm a portion where dew condensation is likely to occur near the suction port 29, thereby preventing dew condensation. Further, the warm air flowing into the exhaust duct 86 rises there as shown in FIG.
Spills towards the outside. Thereby, the outer surface of the outer plate 82, which is easily condensed by the temperature in the display room 13, can be heated, and the dew can be prevented or eliminated.

Here, since the upper end of the exhaust duct 86 is closed by the top plate 8, the pressure (static pressure) at the upper part of the exhaust duct 86 rises, whereby the upper exhaust outlet 87 is formed.
The more warm air flows out, the more. Therefore, it is possible to preferentially supply warm air to the upper portion of the outer surface of the outer plate 82 where dew condensation is most likely to occur in the vicinity of the discharge port 61, so that dew can be effectively eliminated.

The numerical values such as the dimensions shown in the above embodiment are not limited thereto, and can be variously changed within a range suitable for being installed on a desk such as a cashier counter of a convenience store. Further, in the embodiment, a machine room 14 is formed below the heat insulating wall 4 and the compressor 6 of the cooling device R is provided therein.
Although the compressor 3 and the like are installed, the compressor and the condenser may be separately installed and connected to the cooler 18 in the open showcase by a refrigerant pipe, and the compressor and the like may be installed in a cashier counter.
