The air is discharged from the cool air discharge port 42d of the fan portion 42 into the side cold air chambers R1 and R2. 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 is operated during 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 constituting 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 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 drainage tank 55 via the drainage hose 56 which comprises the drainage mechanism 50b, and once it stays in the drainage tank 55, it is discharged via the connection hose 58 and the drainage pipe 57. In the drainage mechanism 50b, as shown in FIGS. 17 and 18, the drainage tank 5
The discharge hole 55a of No. 5 is located 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 shown by the two-dot chain line in FIG. 18), and the drainage hose 56 Since the lower end faces the staying water, the transmission of odor from the drain groove to the drain hose 56 is blocked.

On the other hand, 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 water that drops onto the drain pan 13b is drained from the small hole 57a provided in the drain pipe 57. It is discharged via the pipe 57. In addition, the water dropped on the drain pan 13a also collects water on the drain pan 13a.
The water is discharged from a small hole provided in the drain pipe similar to the drain pipe 57 provided in a through the drain pipe.

As described above, in the ice storage type display stand, the ice generated by the ice making mechanism 20 can be sequentially discharged into the ice storage tank 10b as chip-like ice through the extrusion mechanism 30a and supplied. However, the extrusion mechanism 30a has a function of diffusing the chip-shaped ice that is sequentially discharged to the entire bottom surface of the ice storage tank 10b. Therefore, in the ice storage type display stand, when the operation is started, the ice produced by the ice making mechanism 20 is sequentially discharged as ice chips by the extrusion mechanism 30a into the ice storage tank 10b, and the ice chips are discharged. Ice
The ice chips sequentially discharged from the extrusion mechanism 30a are diffused over the entire bottom surface of the ice storage tank 10b and dispersed substantially evenly.

Thus, according to the ice storage type display stand,
Each display container 18a-1 arranged above the ice storage tank 10b
Although the food and drink in 8f can be held in a cooled state and displayed, a plurality of specially configured receiving members such as the conventional ice storage type display stand, and rotationally driving each of these receiving members This eliminates the need for a plurality of drive motors, which can significantly reduce the cost and prevent the occurrence of a failure due to the rotational drive of each receiving member at all times.

Such an effect is obtained by the first groove portion 3 of the pushing mechanism 30a for guiding the ice generated by the ice making mechanism 20 upward.
Since 1a is formed in a shape in which the upper end thereof has a tapered shape with a smooth bend and opens into the ice storage tank 10b, it can be easily achieved.

Further, the extrusion mechanism 30a has a first groove portion 31a for guiding a part of the ice generated by the ice making mechanism 20 into the ice storage tank, and a first groove portion 31a for guiding the remaining ice above the extrusion mechanism 30a. The pushing mechanism 30 is configured to include the two groove portions 31b.
The transfer mechanism 30b is connected to the upper end of a to stand up, and the transfer mechanism 30b transfers the ice guided from the extrusion mechanism 30a upward and discharges it as chip-like ice into the ice storage tank 10b. Therefore, the discharge state of the chip-shaped ice above the push-out mechanism 30a can be visually recognized by the people around the display stand, attracting the attention of the people, and the display containers 18a to 18a-1.
The display effect of food and drink in 8f can be improved.

In this case, if the display containers 18a to 18f and the shielding plate 19 are transparent, the ice storage tank 1
The storage state of the ice chips in 0b can be visually confirmed, and the display effect can be further improved.

Further, in the ice storage type display stand, the display containers 18a to 18d for storing food and drink are arranged in the upper opening 17a of the ice storage tank 10b without any gap, and the ice storage tank 10 is provided.
upper side of the chip-shaped ice group in b and each display container 18a-18d
The cold air chambers R1 to R3 are formed between the lower surfaces of the cold air chambers R1 to R3, and the cold air circulation mechanisms 40a and 40b for circulating the cold air in the cold air chambers R1 to R3 are provided. The cold air of each display container 18a can be always maintained at a predetermined temperature.
Foods and drinks up to 18f can be cooled almost uniformly at all times.

Further, in the ice storage type display stand, an ice detection mechanism 30c for detecting when the required amount of chip-shaped ice in the ice storage tank 10b reaches a required amount is provided to detect the operating state of the ice making mechanism 20. Since it is configured to control based on the detection signal from the mechanism 30c, the chip-shaped ice in the ice storage tank 10b can be automatically held at a constant amount, and the driver regularly monitors it. It is possible to eliminate the work of operating the ice making mechanism.

Further, in the ice storage type display stand, since the spray mechanism 50a is configured to eject the mist above the display containers 18a to 18f arranged above the ice storage tank 10b, the respective display units are displayed. The mist-like atmosphere above the containers 18a-18f attracts people's attention, and each display container 18a-18
The display effect of the food and drink in f can be further improved.
