The height of the agitator 48 is considerably lower than the predetermined levels La and Lb of the ice stored in the ice storage tanks 21 and 22. The rotation speed of each agitator 48 is about several rotations per minute, and the rotation direction is arbitrary.

As shown in FIGS. 1 to 4, each ice storage tank 21,
A pair of display shelves 30 are provided in the interior 22 of the stirrer 45 over the entire length thereof above the agitator 48. Each of the display shelves 30 of the present embodiment is formed by bending an elongated plate material such as stainless steel so as to have a V-shape with a shallow cross section, and both ends thereof are end shelves made of a plate material fixed to the inner surfaces of the side walls of the ice storage tanks 21 and 22. It is fixed to a receiver 35 by a mounting screw 37, and an intermediate part thereof is supported by an intermediate part shelf receiver 36 made of a rod material protruding and fixed from each cooling cylinder 42 and the overflow pipe 27. A gap is provided between the side edge of each display shelf 30 and each of the ice storage tanks 21 and 22, and a gap a between each of the front and rear side walls of the upper ice storage tank 21 and the front side wall of the lower ice storage tank 22 is about 30 mm. The gap b between the lower ice storage tank 22 and the rear side wall is about 70 mm. Each display shelf 30 forming a pair
The gap c between the side edges is about 1.5 to 2a. The side edge that is the highest part of the display shelf 30 is located below the ice levels La and Lb in the ice storage tanks 21 and 22 by a distance d (about 20 mm).

The display shelf 30 in the upper ice storage tank 21 has a cutout 3 at a position corresponding to the cooling cylinder 42 of the ice making supply device 40.
1a is formed, and a gap e formed between the cooling cylinder 42 and the display shelf 30 formed thereby is about 35 to 45 mm. A notch 31b is formed in the display shelf 30 in the lower ice storage tank 22 at a position corresponding to the overflow pipe 27,
The gap f formed between the overflow pipe 27 and the display shelf 30 is about 30 to 40 mm. Each chip

Each display shelf 30 can pass in the vertical direction. A large number of relatively small drainage holes 32 are provided at the lowermost portion in the center of each display shelf 30.
Are formed.

The ice storage type showcase is used by placing a product or a container for storing the product on each display shelf 30.
When the ice making supply device 40 is operated, the automatically produced ice is cut out from the ice discharge port 42a at the upper end of the cooling cylinder 42 by the cutout portion 31a.
Then, the ice drops gradually to the bottom of the upper ice storage tank 21 through the gap e formed by the above, and the ice level gradually rises while being automatically leveled by being stirred by the stirring device 45. When this ice level reaches the lower end of the display shelf 30, each chip-shaped ice rises by dividing along the upward slope of the lower surface, and each of the gaps a, c,
From e, it moves over the edge of the display shelf 30 and moves upward to cool the product or its container placed thereon. If the ice level further rises and exceeds a predetermined level La, the partition plate 2
1a, falls into the bottom of the lower ice storage tank 22 through the gap b from the notch 21b (overflow device) at the upper edge.

The ice falling into the bottom of the lower ice storage tank 22 is leveled by the stirrer 45 as in the case of the upper ice storage tank 21 and rises in ice level, and moves to the upper side of the display shelf 30 to be placed thereon. When the product or its container is cooled and exceeds a predetermined level Lb, the product is discharged into the drain tank 25 from the opening at the upper end of the overflow pipe 27 (overflow device). Ice passing through the overflow pipe 2 7 when this is detected by the ice detector 28, the operation of the ice making supply unit 40 by the control device is temporarily stopped. The ice melt on each display shelf 30 is drained from a drain hole 32 at the bottom to each ice storage tank 21,
The molten water that has fallen to the bottom of the tank 22 and accumulated at the bottom is discharged to the drainage tank 25 through the connection pipes 26a and 26b.

The ice on the lower side of the display shelf 30 moves while being stirred by the stirring device 45, but the ice on the upper side of the display shelf 30 is slightly moved since it is blocked by the display shelf 30. Therefore, the product placed on the display shelf 30 and the container for storing the product are stably held, and there is no inconvenience to the product. In addition, the shape of the product and the container placed on the display shelf 30 is free, and the product can be freely taken in and out. As shown in FIG. 5, the stability can be further improved by providing a cage 33 with a bar welded on the display shelf 30 and placing a product or its container thereon.

In this embodiment, since the sectional shape of the display shelf 30 is a shallow V-shape, the ice stirred by the stirring device 45 easily rises along the lower surface of the display shelf 30, so that a stable ice level can be obtained. Then, the movement to the upper side of the display shelf 30 and the discharge from the overflow devices 21b and 27 are also performed smoothly. However, the cross-sectional shape of the display shelf 30 of the present invention may be a shallow curved shape as shown in FIG. 6 or a flat shape as shown in FIG. Further, as shown in FIG. 8, bars may be combined in a lattice shape by welding or the like instead of the plate.

In this embodiment, both side edges of the display shelf 30 are set at positions lower than predetermined levels La and Lb.
A considerable amount of ice is present on the upper side of the display shelf 30 and moves a little , so that the goods and their containers are cooled directly, so that the cooling efficiency is improved and the display shelf 30 is hidden. The display effect also improves. However shelves 30 located level La of its highest portion, Lb and Ho Isuzu rather it may also be increased to the same extent, thus substantially similar effects are obtained, et al.
It is .

FIG. 9 shows examples of display shelves 30 having different arrangements. In this example, four elongated display shelves 30 are arranged in parallel so as to have a shallow V-shaped cross section as a whole. Figure 10 is bent so as to further different display example of the shelf 30 is parallel-arranged four shelves 30 are both shallow V-shaped cross-section. 9 and 10 is substantially the same as that of the above-described embodiment, and each of them has a cooling cylinder 42 and an overflow pipe 27.
A notch is formed at a position corresponding to. FIG.
A plurality of drain holes are formed in the central portion, which is the lowest portion of each display shelf 30.
