[Modification] In the above-described embodiment, one blower and one heater are provided corresponding to the storage section defined in the hot air storage.
Although the bases are arranged, a plurality of blowers and heaters may be arranged in accordance with an increase in the volume of the storage portion. In such a case, there is a fear that the hot air from each blower interferes with each other and the circulation efficiency of the hot air in the storage unit is reduced. Further, there is also a drawback that the size of the storage section becomes large, which causes a large variation in the air volume in the storage section. Therefore, for example, as shown in FIG. 10, when two blowers 15 and 15 are arranged in the front and rear in the center of the upper space 27 in the width direction, and heaters 16 are arranged on both the left and right sides, respectively, Partition plate 70 for partitioning the space between the blowers 15 and 15 into front and rear
Are provided over the entire width of the upper space 27. In this case, since the blower 15 and the heater 16 are located in the independent space partitioned by the partition plate 70, the hot air from each blower 15 does not interfere with each other, and the circulation efficiency of the hot air in the storage unit is improved. Can improve. Furthermore, by providing the partition plate 70, variations in the amount of hot air can be suppressed. Moreover, since the device has the same configuration as that of two devices having half the size in the front-rear direction, which are arranged in the front-rear direction, the instrumentation and development period becomes short.

In the modification shown in FIG. 10, the upper space 2 is
7 is completely divided into two by a partition plate 70, and a blower 15 and a heater 16 are provided in each space.
As shown in FIG. 1, the partition plate 71 may be used to partition the air blower 15, 15 into the front and back. In this case as well, the partition plate 7 prevents interference of hot air from both blowers 15 and 15.
1 can effectively prevent it, improve the circulation efficiency of the hot air in the storage chamber, and suppress the variation in the amount of the hot air.
In addition, since it is not necessary to partition the parts where the heaters 16 and 16 are provided, the structure of the upper space 27 can be simplified, and the cost can be reduced and the work can be facilitated.

In the drainage structure of this embodiment, the drain pipe is screwed into a nut separate from the support plate. However, the drain pipe is screwed into a screw hole provided as a fixing portion in the support plate. The configuration can be adopted. Further, although the drain pipe is also used as the connecting member in the embodiment, the bottom plate and the support plate may be connected by a connecting member which is a member different from the drain pipe. Further, in the embodiment, two storage chambers are defined in parallel in the heat insulating box, but the number of storage chambers may be one, and the bottom plate of the outer box body is a single plate and the rigidity is increased. ,
The bottom plate can also be used as a support plate.

In the above-mentioned embodiments and modified examples, as a device adopting the drainage structure according to the present invention, hot-air storage in which hot air is circulated in the storage portion of the heat-insulating box to dry and disinfect dishes and the like. Although the case has been described as an example, the present invention is not limited to this, and can be suitably applied to, for example, a refrigerator, a freezer, etc., as long as a drain pipe is arranged on the bottom plate, Can also be adopted.

[0036]

As described above, according to the drainage structure of the present invention, when the support plate and the bottom plate, which are arranged below the bottom plate and are spaced apart from each other, are connected to each other through the connecting member, Since the disposing portion of the drainage pipe is configured to be displaced close to the support plate, it is possible to impart a downward inclination toward the drainage pipe without drawing the bottom plate. That is, it is possible to suppress an increase in the processing cost due to the drawing process, prevent the occurrence of flaws and the like accompanying the processing, and improve the product quality. Further, by using the drainage pipe as the connecting member, the number of parts can be reduced.
