When the cooling fan 24 is operated, the cooler 2
The cold air cooled in 2 is blown out to the discharge side duct 8A of the duct 8 as shown by the arrow in FIG. 3, flows down from the upper surface 3A of the storage box 3 to the back and side, and flows under the bottom surface of the storage box 3. The circulation is performed by flowing into the return duct 8B, moving up the return duct 8B and returning to the suction side of the cooler 22. The wall surface of the storage box 3 is cooled by such cold air circulation, and the inside of the storage chamber 6 is indirectly cooled from the wall surface of the storage box 3. As described above, the storage chamber 6 is indirectly cooled by the wall surface of the storage box 3, and the inside thereof is, for example, −5 ° C. to + 13 ° C. due to the evaporation action of water from the food or the like stored inside and the water entering from the outside.
It is configured to be cooled and maintained at a high humidity of 80% to 90% within the range.

The upper surface 3A of the storage box 3 is inclined rearwardly low, and the upper surface 3A is further integrally bent with a rectangular recess 5 projecting toward the duct 8 (space between the heat insulating box 2). Has been formed. The upper surface of the recess 5 is located above the drain pan 23.
And have sufficient spacing. Then, in the recess 5, there is a predetermined space below the upper surface 3A and along the slope thereof,
A dew receiving plate 30 which is inclined rearward is arranged low. In addition, the storage box 3 at the bottom of the storage chamber 6 has a bottom wall 2B of the heat insulating box 2.

The dew receiving plate 30 is formed of, for example, a stainless steel plate, and a pair of jetty portions 31, 31 standing upright and extending in the front-rear direction are bent and formed on both left and right sides of the dew receiving plate 30. Left and right flange portions 32, 32 protruding horizontally in the lateral direction are continuously bent from the lower ends of the jetty portions 31, 31. Further, a rear flange portion 37 projecting obliquely rearward and downward is also continuously bent at the rear end of the dew receiving plate 30.

On the other hand, on the top surface of the recess 5, mounting members 38 ... Having a substantially inverted gate cross section are mounted.
The dew receiving plate 30 is directed from below to the resin bushing 3
By further fitting 9 from below, the dew receiving plate 3
0 is inclined and fixed in the recess 5 with a predetermined distance from the top surface (the upper surface 3A of the storage box 3).

At this time, the main body of the dew receiving plate 30 including the jetty portions 31 and 31 is housed in the recess 5, but the left and right flange portions 32 and 32 are left and right to the outside of the recess 5 as shown in FIGS.

Since 31 is formed, the dew condensation water dropped from the recess 5 portion corresponding to the jetty portions 31, 31 can be smoothly flowed backward. Further, the jetty portions 31, 31 are laterally projecting from the lower ends of the jetty portions 31 and extend to the outside of the recess 5, and the left and right flange portions 3 are provided.
Since the portions 2 and 32 are formed, the left and right flange portions 32 and 32 can also receive the dew condensation water dropped from the recess 5 in the portion located outside the jetty portions 31 and 31. Thereby, the dew condensation water dropped from the recess 5 on the upper surface 3A of the storage box 3 can be reliably received and the waste water can be treated.

Further, since the recess 5 is formed above the mounting surface 34A of the shelf 34 installed in the storage chamber 6, the dew receiving plate 30 is located above the mounting surface 34A of the shelf 34. As a result, it is possible to reliably prevent the dew condensation water from falling onto at least the articles placed on the shelf 34.
