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 chip-shaped ice in 6 is gradually melted and water is generated in the ice storage tank portion 16. The generated water is the bottom portion 1 of the ice storage tank portion 16.
From the discharge hole 16e provided in 6a, it flows out to the discharge tank 55 through the discharge hose 56 which comprises the drainage mechanism 50b, and once stays in the discharge tank 55, it is discharged through the connection hose 58 and the discharge pipe 57. In the drainage mechanism 50b, as shown in FIG. 17 and FIG.
The discharge hole 55a of No. 5 is located higher than the bottom of the discharge tank 55, a predetermined amount of water always stays at the bottom of the discharge tank 55 (the water level shown by the two-dot chain line in FIG. 18), and the discharge hose 56 Since the lower end portion faces the accumulated water, the transmission of odor from the drain groove to the discharge hose 56 is blocked.

On the other hand, the dew condensation water generated by dew condensation on the outer periphery of the ice storage tank 10b or 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 ice storage type display stand constructed as described above, the water generated by melting the ice chips in the ice storage tank during operation is discharged from the discharge hole 16e provided at the bottom of the ice storage tank section 16 to the discharge hose. It is discharged to the outside through 56, the discharge tank 55, the connecting hose 58, and the discharge pipe 57. In addition, the ice storage tank 16
When dew condensation occurs on the outside of the
It travels through a or falls and reaches the drain pans 13a and 13b, and is discharged to the outside through the drain pans 13a and 13b. Therefore, the condensed water does not directly leak to the outside of the display stand.

In the ice storage type display stand, the water received on the drain pan 13b is discharged to the discharge pipe 5 on the peripheral wall of the discharge pipe 57.
Since the inflow hole 57a that directs the inside of the drain 7 is formed, the dew condensation water received by the drain pan 13b is discharged through the discharge pipe 57.
Is introduced into the discharge pipe 57 through the inflow hole 57a of
It is discharged to the outside together with the drainage that flows out inside 7.

In addition, in the ice storage type display stand, since the inclined portions 13a1 and 13b1 which descend and incline inward are formed on the outer end sides of the drain pans 13a and 13b, the ice storage tank portion 16 is further supported by the support frame 11. A water escape hole 11b for directing the condensed water to the downward direction is formed on the shelf portion 11a, and the water escape hole 11b is formed in the inclined portion 13a of the drain pans 13a, 13b.
Since it is located above 1, 13b1, the ice storage tank section 16
The dew condensation water generated on the outside of the is reliably received by the drain pans 13a and 13b and discharged.

Further, in the ice storage type display stand, the discharge hole 16e provided at the bottom of the ice tank portion 16 is fitted with the lid 56a which allows passage of water and regulates passage of ice. Only the water in the ice storage tank portion 16 can be reliably discharged, and the water in the ice storage tank portion 16 can be reliably discharged without the chip-like ice clogging the discharge hose 56.
