A bottom plate 10 serving as a bottom wall of the lower storage chamber 4 is provided above the bottom wall 2A of the lower heat insulating box 2, and a cold air passage 11 is formed in the bottom wall 2A below the bottom plate 10. In the cool air passage 11, a cooler 12 and a blower 13 included in a known refrigeration cycle are housed and arranged. The cool air cooled by the cooler 12 is discharged into the lower storage chamber 4 from a discharge port 14 formed at the rear end of the bottom plate 10 and circulates through the lower storage chamber 4 to cool the western confectionery and the like displayed and stored therein. After that, it is sucked into the cool air passage 11 from the suction port 15 formed at the front end of the bottom plate 10. Reference numeral 37 denotes a tray mounting table provided on the front surface of the bottom wall 2A.

Reference numeral 25 denotes a transparent glass door having an arcuate cross section for closing the opening 3 of the lower storage chamber 4 so as to be openable and closable, and is provided in front of the rear wall 2B on both sides of the opening 3 of the lower insulating box 2. It is slidably mounted on a semi-circular rail 38 made of stainless steel. When the door 25 is in the closed state, the lower side 2
6A contacts the frame member 39 in front of the suction port 15, and the upper side 26B
Is located below the front of the upper wall 2C and slightly behind the apex of the rail 38. Reference numeral 41 is a cover that covers both sides of the door 25. Reference numeral 44 denotes an illumination provided between the lower surfaces of the tops of the rails 38, 38. Reference numeral 45 is a motor provided in the drive means storage chamber 9, which drives the gears 51 meshing with the upper surfaces of both sides of the door 25 via the belt 50 to automatically open and close the door 25 on the rail 38. Reference numeral 56 is a cover of the drive means storage chamber 9.

On the other hand, a back plate 16 forms a cool air passage 17 vertically at the back of the upper storage chamber 8 of the upper heat-insulating box 5, and a cooler 18 is vertically installed in the cool air passage 17 and above it. A blower 19 is arranged in the cold air passage 17.
The front part has an opening 7 in front of the blower 19 in the upper part of the upper storage room 8.
A mirror 20 of the present invention is attached which extends near the rear of the upper edge and is inclined rearward low. The cool air discharge port 21 opened downward is provided between the mirror 20 and the upper edge inside the opening 7 in front of the front end of the mirror 20.
Is formed. Further, reference numeral 23 is a door having a transparent glass for closing the opening 7 of the upper storage chamber 8 so as to be openable and closable.

Due to these arrangements, the blower 19 has the mirror 20.
The cool air, which is located in the back of the vehicle and is cooled by the cooler 18, is sucked upward by the operation of the blower 19 and then blown out forward. The cool air blown to the back of the mirror 20 is guided to the front cool air discharge port 21 along the back surface of the mirror 20,
The cold air discharge port 21 blows into the upper storage chamber 8.
The cold air blown into the upper storage room 8 descends inside the opening 7 and circulates inside the upper storage room 8 to cool the exhibited confectionery and the like, and then is sucked from the cold air suction port 22 formed at the lower edge of the opening 7. Then, the circulation to return to the cold air passage 17 is performed. 2
Reference numeral 4 denotes an illumination mounted between the cold air discharge port 21 and the mirror 20 behind the cooling air discharge port 21, and side plates (not shown) are attached to the sides of the upper and lower heat insulating boxes 5 and 2.

Since the upper heat-insulating box 5 is supported above the lower heat-insulating box 2, it becomes difficult for the customer to see the products in the upper storage chamber 8, but the products below the mirror 20 are reflected in the mirror 20 and forward. Alternatively, since it can be seen from the lower front, the customer can easily select the product. At the same time, the mirror 20 serves as a guide plate for guiding the cool air from the blower 19 to the cold air discharge port 21, so that a special duct plate can be omitted. Further, since the mirror 20 is arranged so that the front is high and the rear is low, even if dew condensation occurs on the front and back surfaces of the mirror 20 due to the entry of outside air or the evaporation of water from the displayed product, the cold air passage 17 or Since the water can be collected in the rear part of the upper storage room 8 by natural fall, the condensed water does not fall on the exhibited products.

In the embodiment, the upper heat insulating box 5 having the upper and lower heat insulating boxes 5 and 2 and the upper and lower storage chambers 8 and 4 is provided.
Although the present invention is applied to the present invention, it is needless to say that the present invention is effective even in a single storage room or an open type showcase.

[0015]

According to the present invention, the cool air cooled by the cooler is sucked by the blower, blown out toward the front mirror, and then is guided forward along the rear surface of the mirror to discharge the cool air in front of the front end thereof. Since it is discharged into the storage chamber from the outlet, the cool air can be smoothly blown out from the opening into the storage chamber without providing a special duct plate, and the number of parts can be reduced and the work process can be simplified.

Further, since the products on display in the storage room are reflected on the mirror which is inclined upwards, the visibility of the products from the front or the lower front is also improved.
