Since the cool air sucked into the circulation fan unit 42 is discharged obliquely downward from the cool air discharge port 42d located below the cool air suction port 42c, the cool air in each side cool air chamber R1, R2 is indicated by a solid arrow in FIG. It circulates and flows as shown in.

The spray mechanism 50a operates during the operation of the ice storage type display stand, and a large amount of fog generated by the fog generator 51 is supplied by the blower 52 into the cylindrical body 34 which constitutes the transfer mechanism 30b. The mist is cooled in the cylindrical body 34 and is ejected as white mist from each ejection hole 34a provided in the upper end portion of the cylindrical body 34. The spouted mist slowly flows on each of the display containers 18a to 18f as shown by the solid line in FIG. 19 to prevent the food and drink from drying and to enhance the display atmosphere.

In the ice storage type display stand, the ice storage tank unit 1
The ice chips in 6 are gradually melted to generate water in the ice storage tank portion 16. The generated melted water is discharged from the drain hole 16e provided in the bottom portion 16a of the ice storage tank portion 16 to the drainage mechanism 50b. It flows out to the drainage tank 55 through the drainage hose 56 that constitutes it, and once stays in the drainage tank 55, it is then connected to the connection hose 5.
8 and the discharge pipe 57. Drainage mechanism 50
17b, as shown in FIGS. 17 and 18, the drain hole 55a of the drainage tank 55 is located at a position higher than the bottom of the drainage tank 55, and a predetermined amount of water always stays at the bottom of the drainage tank 55 ( The water level indicated by the chain double-dashed line in FIG. 18) and the lower end of the drainage hose 56 faces the accumulated water.

On the other hand, the dew condensation water generated by dew condensation on the outer periphery of the ice storage tank 10b and the like drops into the drain pans 13a and 13b, but the dew condensation water that drops on the drain pan 13b is an inflow hole 57a provided in the discharge pipe 57. Is discharged through the discharge pipe 57. The dew condensation water that has dropped onto the drain pan 13a is also discharged from the inflow hole provided in the same discharge pipe as the discharge pipe 57 provided in the drain pan 13a through the same discharge pipe.

In the drainage mechanism 50b of the ice storage type display stand configured as described above, the drainage hole 16e provided in the bottom portion of the ice storage tank 16 is the opening portion of the first groove portion 31a of the extrusion mechanism 30a which is the discharge portion of the ice chips. Since it is located below, the melted water of the ice in the ice storage tank 16 is promptly discharged from the drain hole 16e, the melted water stays in the ice storage tank 16 and is discharged from the chip-shaped ice to the ice making mechanism 20 side. There is no such thing as backflow to.

In the drainage mechanism 50b, the drainage hole 16e is formed to have a large diameter, and the drainage hole 16e regulates the passage of chip ice and allows the passage of water.
Since it is covered with the lid 56a having a1, the chip-like ice in the ice storage tank 16 is prevented from falling into the drain hose 56 through the drain hole 16e, and the cold air discharge hole 16e in the ice storage tank 16 is also prevented. From the drain to the drain hose 56, and the inflow of odor from the drain hose 56 into the ice storage tank 16 through the drain hole 16e is suppressed.

In the drainage mechanism 50b, the drainage hole 55a is formed in the drainage tank 55 at a position higher than the bottom by a predetermined height, and the lower end of the drainage hose 56 is disposed in the drainage tank 55 from the drainage hole 55a. Since the drain hose 56 faces downward, the lower end of the drain hose 56 is closed by the molten water accumulated in the drain tank 55, and the cold air in the ice storage tank 16 leaks to the outside through the drain hose 56 and the drain hose 56.
Through this, the odor of external waste water is prevented from flowing into the ice storage tank 16.

In the drainage mechanism 50b, the lid 56a is removed from the drainage hole 16e when the inside of the ice storage tank 16 is cleaned. As a result, the drain hole 16e returns to the original large-diameter drain hole, and the melted water and the cleaning water stored in the ice storage tank 16 can be quickly discharged.
