FIG. 7 is a partial cross-sectional view showing a main part of a schematic configuration of the base frame and the outside air guide member 7 of the prefabricated refrigerator-freezer according to the third embodiment. The prefabricated refrigerator-freezer 40 according to the third embodiment is the same as the first embodiment.
It has basically the same configuration as the prefabricated refrigerator-freezer 1 according to the embodiment. However, as shown in FIGS. 6 and 7,
The configuration of the insertion member 41 inserted into the base frame 6 of the outside air guide member 7 is the same as that of the outside air guide member 7 according to the first embodiment.
Of the insertion member 7A. Therefore, in the following description, the prefabricated refrigerator-freezer 1 of the first embodiment will be described.
The same members and elements as those described in above are denoted by the same reference numerals. The insertion member 41 inserted into the base frame 6 of the outside air guide member 7 is made of a resin pipe such as hard vinyl chloride or a metal pipe.

As shown in FIGS. 6 and 7, the insertion members 41 connected to the respective hot air outlets of the outside air guide member 7B of the outside air guide member 7 have substantially the same length and substantially cylindrical exhaust cylinder members 41.

The warm air blown out by the warm air blower 8 into the 2C is sent out through the outside air outlet 42 of the insertion member 41 constituting the outside air guide member 7.

As a result, the lower surface of the heat insulating box 4 where dew condensation occurs is heated by the warm air blown out from the outside air outlet 42 of the insertion member 41 constituting the outside air guiding member 7. It is possible to effectively prevent the occurrence of dew condensation on the lower surface of the substrate. Further, by disposing each insertion member 41 of the outside air guide member 7 in a space between the lower surface of the heat insulating box 4 and the floor surface at a position which is substantially equally divided into four in the front-rear direction (vertical direction in FIG. 2). Since the entire lower surface of the heat insulating box 4 where dew condensation occurs can be heated, the heat insulating box 4 can be heated.
The occurrence of dew condensation on the lower surface of the device can be reliably prevented. Further, the base frame 6 and the reinforcing frames 11, 1
Even if 1 is made of H-section steel or the like, the base frame 6 and the reinforcing frames 11, 11 can be heated simultaneously, so that dew condensation on the base frame 6 and the reinforcing frames 11, 11 can be prevented. Further, the insertion member 41 of the outside air guiding member 7 is provided with exhaust cylinder members 41A, 41 of a predetermined length.
A and 41A are connected, so that by adjusting the number of connected exhaust cylinder members 41A, an insertion member 41 having an arbitrary length can be manufactured and manufacturing cost can be reduced. Can be. Further, since there is no need to provide a drainage groove or the like on the floor on which the prefabricated refrigerator 40 is installed, the prefabricated refrigerator 40 can be installed at any location. Further, since the hot air can be forcibly sent out into the outside air guide member 7 by the hot air blower 8, the warm air is blown into the space between the lower surface of the heat insulating box 4 and the floor via the outside air guide member 7. Hot air can be reliably sent, and the occurrence of dew condensation on the lower surface of the heat insulating box 4 can be reliably prevented. Further, since the operation of forming the outside air outlet 42 of the exhaust tube member 41A constituting the insertion member 41 of the outside air guide member 7 is simple, the manufacturing cost can be reduced. Further, the warm air blown out from the insertion member 41 of the outside air guide member 7 is discharged outside through the air holes 6A and the communication holes 11A in which the insertion member 41 of the outside air guide member 7 is not inserted. The lower surface of the heat-insulating box 4 can be always heated with warm air, and the occurrence of dew condensation on the lower surface of the heat-insulating box 4 can be reliably prevented. Further, since the base frame 6 is reinforced by the reinforcing frame 11, the base frame 6 can be formed of an H-shaped steel or the like, and the manufacturing cost can be reduced. In addition, since the insertion member 41 inserted into the base frame 6 can be constituted by a resin pipe or the like, it is possible to reduce the manufacturing cost and increase the efficiency of the assembling work. Further, since the insertion member 41 of the outside air guide member 7 is formed to be thinner than the air hole 6A and the communication hole 11A, it is easy to insert the insertion member 41 into each of the air hole 6A and the communication hole 11A. Because you can
The efficiency of the assembling work can be improved.
