In addition, drainage | condensation water, defrost water, etc. which generate | occur | produce in the cooler 26 do not hold | maintain between each fin 26a, and each drainage part of the drain pan 26f ( 26g) and flows from the drain port 26h to the second bottom surface side ventilation passage 21b. Thereby, the heat exchange area of the cooler 26 does not decrease, and cooling efficiency does not fall.

As described above, according to the showcase of the present embodiment, the air introduced into the bottom side ventilation path 21 from each air inlet 21d is guided to the air inlet side of the cooler 26, so that one cooler 26 is guided. The product storage unit 15 can be cooled by the cooling device having a simple structure, which facilitates temperature control and defrost control. In addition, even in a case where the temperature and humidity of the external air penetrating into the product storage unit 15 from each opening are different, stable cooling capacity can be maintained.

In addition, the bottom side ventilation path 21 has a first bottom side ventilation path 21a formed along each air inlet 21d and a second bottom side ventilation hole formed below the first floor side ventilation path 21a. Each air intake port is formed of the third floor surface side ventilation passage 21c formed above the furnace 21b and the second floor side ventilation passage 21b and on which the cooler 26 and the cooler blower 27 are arranged. The air sucked from each of 21d is sequentially distributed to the first bottom side ventilation passage 21a, the second bottom side ventilation passage 21b, and the third bottom side ventilation passage 21c to be passed to the cooler 26. In addition, it is not necessary to arrange the cooler 26 over the width direction of each air suction port 21d, and the size of the cooler 26 can be reduced.

Moreover, since the air is sucked uniformly over the width direction of each air inlet 21d, the air inside the goods storage part 15 can be sucked in from each air inlet 21d, without bias, and the goods storage part 15 The internal temperature can be made uniform.

In addition, the partition plate 21e divides the 1st bottom surface side ventilation path 21a and the 2nd bottom surface side ventilation path 21b by the partition plate 21e, and in the partition plate 21e with a short distance from the cooling fan 27 for coolers. The opening ratio of the communication hole 21f in the partition plate 21e, which is longer than the opening ratio of the communication hole 21f of the cooler, is increased so that the air flows in the width direction of each air inlet 21d. Since it is made to suck uniformly, air can be sucked uniformly over the width direction of each air suction opening 21d by a simple member, and manufacturing cost can be reduced.

In addition, a drain receiving part 26g provided below the cooler 26 and formed of an inclined surface in which drainage generated in the cooler 26 flows in a predetermined direction, and a drain hole 26h disposed at the lowermost end of the drain receiving part 26g. Since the drain pan 26f which has () is provided, it drains the drainage which generate | occur | produces in the cooler 26 to each drain receiving part 26g of the drain pan 26f, without remaining between each fin 26a, Since it can distribute | circulate from the drain port 26h to the 2nd bottom surface side ventilation path 21b, the heat exchange area of the heat exchanger 26 is not reduced and it becomes possible to prevent the fall of cooling efficiency.

In addition, since a plurality of drain pans 26g of the drain pan 26f are provided in the drain pan 26f, the length of the inclined surface of each drain pan part 26g can be shortened, so that the drain pan 26f The dimension of an up-down direction can be formed small.

In addition, since a plurality of drain pans 26g of the drain pan 26f are provided in the longitudinal direction of the drain pan 26f, even when the inclined surface is provided so as to be inclined with respect to the longitudinal direction of the drain pan 26f, the drain pan ( The dimension of the up-down direction of 26f) can be formed small.

Moreover, since the air is discharged uniformly over the width direction of each air discharge port 23a, the temperature of the goods storage part 15 can be kept uniform without bias, and the goods of the goods storage part 15 can be surely cooled. Can be.

In addition, a plurality of first air guide plates 28a are installed on the upper surface of the upper product cooling ventilation path 23 so as to go straight to the flow direction of the air, and are spaced apart from each other in the flow direction of the air. Since the air guide plate 28a is formed so that the dimension in the up-down direction is longer than that of the adjacent upstream air guide plate 28a, air is uniformly discharged over the width direction of each air discharge port 23a. By this, the air can be discharged uniformly over the width direction of each air discharge port 23a, and the manufacturing cost can be reduced.

Since each first air guide plate 28a is inclined so that the lower end side faces the air flow direction, each air discharge port 23a is efficiently carried out by the first air guide plate 28a without impeding the flow of air. To guide the air.
