Furthermore, as shown in FIG. 5, a drain pipe 65 is provided at the drain port 63 of the lower plate 64 of the cold air circulation duct 6.
The head is closely attached to the lower plate 64 with the head protruding a predetermined length above the lower plate 64. Further, the head of the drain pipe 65 is covered with a cold air leakage prevention cap 68. This cold air leak prevention cap 68 allows water to flow into the drain pipe 65 from outside the cap. Specifically, the head of the drain pipe 65 has a depth that is greater than the protrusion length from the lower plate 64 of the head, and an inner circumferential shape that is greater than the outer circumferential shape of the head. A leak-proof cap 68 is placed over the cap, and two flow holes 68a are provided at the bottom of the cold-air leak-proof cap 68 to allow water (67 in FIG. 5) to flow inside and outside the cap. According to such a structure, a certain amount of water (67 in FIG. 5) can be secured on the lower plate 64 of the cold air circulation duct 6, which functions as a dew pan, and a certain amount of water can be secured with the cold air leakage prevention cap 68. This water can prevent cold air from leaking out of the cooling device through the drain pipe 65. In addition, the cold air passing through the cooler 7
It is applied to the water 67 stored in the lower part of the cold air circulation duct 6, becomes moist cold air, and is sent into the show case, making it possible to prevent the products from drying out.

Then, by the blower 5, the suction hole 61,
A flow of air is created between the cooler 7, the cold air partition vertical plate 9, and the cold air circulation duct 6, passing through the blow-off holes 62 in sequence.

To explain the cooling device of this embodiment in detail, a cooler 7 is installed upright below a surface 8 of the heat insulating board 2 on the inside of the refrigerator. A cold air partition vertical plate 9 is attached to the inside surface of the cooler 7, and cold air partition horizontal plates 3 are mounted on both sides of the upper surface of the cooler 7. A gasket 12 is provided between the plate 13 of the cooler 7 and the horizontal cold air partition plate 3 and at the upper end of the vertical cold air partition plate 9 to prevent cold air from leaking.
is pasted. A blower 5 is attached to a blower attachment duct 4 provided in the cold air circulation duct 6. The cold air circulation duct 6 is fixed by fixing the attachment hole 10 portion provided in the cold air circulation duct 6 to the plate 13 of the cooler 7 with screws or the like.

In order to secure a certain amount of evaporated water on the lower plate 64 of the cold air circulation duct 6 and to prevent cold air from leaking outside the cooling device, as shown in FIG.
The drain pipe 65 is inserted into the drain port 63 of the drain pipe 63 while being press-fitted, and a cap 68 for preventing cold air leakage is further placed over the upper surface of the inserted drain pipe 65. As shown in FIG. 6, the cold air leak prevention cap 68 has a plurality of convex portions 68b on its inner peripheral surface and is press-fitted onto the outer periphery of the head of the drain pipe 65.

Furthermore, as shown in FIG. 5, in order to prevent cold air from leaking from the inside of the show case to the outside of the show case, a cold air leakage prevention ring 69 (the detailed structure is shown in FIG. 7) is attached to the outer peripheral surface of the lower part of the drain pipe 65. A water reservoir 2 for collecting drainage water 67' provided on the top surface of the bottom plate 202 of the show case is inserted while press-fitting.
The lower end of the cold air leakage prevention ring 69 is placed inside the cold air leak prevention ring 69. The outer surface of the water reservoir 202a is in contact with the heat insulating material 2'. This heat insulating material 2' is provided with a drainage hole 202b at a position corresponding to the drainage pipe 65, and this drainage hole 202b allows drainage and water overflowing from the lower plate 64 of the cold air circulation duct 6 to be removed. Drainage water overflowing from the reservoir 202a is guided to the drainage tank 66 as indicated by the arrow. Variations in dimensions between the cold air circulation duct 6 and the bottom plate 202 of the case can be accommodated by adjusting the position of the cold air leak prevention ring 69 with respect to the drain pipe 65.

Next, the effects of the present invention will be listed.

By removing the cooler from the ceiling,
Products can be seen clearly from the ceiling, and in-store lighting can be brought in directly through the glass ceiling of the show case. Additionally, there is no need for lighting inside the refrigerator, resulting in energy savings.

It is sucked in from the suction hole 61 in the upper part of the refrigerator,
Furthermore, the cold air that has passed through the cooler 7 is
is equalized at the bottom. This homogenized cold air is squeezed between the cold air partition vertical plate 9 provided on the inside surface of the cooler 7 and the cold air circulation duct 6, and the cooled air is further cooled on the lower surface of the cooler 7. The air is blown out from the blow-off hole 62 which is higher up and below the suction hole 61. This structure makes it possible to maintain a uniform temperature inside the show case.

Since the blower 5 is provided above the cooler 7, there is no risk that water generated by defrosting the cooler 7 will stick to the blower 5, and the problem of poor dielectric strength of the blower 5 is also alleviated.

Since the cold air circulation duct 6 can be easily attached and detached, it is convenient for after-sales service.

The cold air circulation duct 6 has a cold air suction function, a cold air blowing function, and a dew receiving tray function.

Defrosted water from cooler 7 (67 in Figure 5)
A certain amount of cold air can be collected on the lower plate 64 of the cold air circulation duct 6, which functions as a dew pan, and a cold air leak prevention cap 68 prevents cold air from leaking out of the cooling device through the drain pipe 65. can be prevented. In addition, the cold air that has passed through the cooler 7 is applied to the water 67 stored at the bottom of the cold air circulation duct 6, and is turned into moist cold air and sent into the show case, thereby preventing the products from drying out. became possible.
