The drain guide 7 is configured to be inclined toward the front from the place where the cooler is disposed. The drain guide 7 and the drain port 8 are coupled so that drainage does not leak. The eaves 13 are provided below the drainage port 8 and function to collect the drainage from each of the storage chambers in one place and to flow into the drain water evaporator 3.

  2 is a perspective view of the drain guide 7 in the first embodiment of the present invention, FIG. 3 is a perspective view of the drain port 8 in the first embodiment of the present invention, and FIG. 4 is the first view of the present invention. It is sectional drawing of the drain port 8 in the embodiment.

In FIG. 2, the drain guide 7 is composed of an upper guide 9 and a lower guide 10, and has a structure in which drainage does not leak. The upper guide 9 is provided with an opening 11 for receiving the drainage of the cooler 2. A drainage portion 12 coupled to the drainage port 8 is provided on the front surface of the drain guide 7. The drainage portion 12 has a narrowed tip, and drains drain water from a drainage hole 15 provided at the tip of the lower guide 10.
A dam 14 is provided around the opening 11 of the upper guide 9 and plays a role of blocking the drain water that has fallen off the opening 11 so as not to flow down. The weir 14 may be constituted by sticking a foam or may be provided by extruding the upper guide 9. The height of the weir 14 needs to be such that when drain water is accumulated in the weir 14, it flows down to the opening 11 before flowing out from the weir 14.

  In order to reduce the height of the weir 14 as much as possible, it is also effective to provide a hole in the upper guide 9 in the vicinity of the inner side of the weir 14 in order to allow the drain water accumulated inside the weir 14 to flow to the lower guide 10. .

  In FIG. 3, a drainage inlet 16 that receives drain water from a drainage hole 15 provided at the tip of the lower guide 10 is provided at the upper part of the drainage outlet 8, and a cylindrical drainage outlet 17 is provided on the side surface.
