Can be efficiently drained to the drainage path,
It becomes possible to effectively remove the condensed water.

The condensed water received by the water receiving portion 33 as described above gathers at the lower portion of the receiving member 16 due to gravity. Then, the condensed water collected in the lower portion of the receiving member 16 flows into the storage chamber 6 through the communication portions 32A, 31A, 29A and the drain holes 34. A drain hole (not shown) is formed in the heat insulating wall 4 below the storage chamber 6, and the dew condensation water is drained from this drain hole together with defrosting water of the cooler.

2, 42, ...
The outer surface of 2 may be horizontally attached at a predetermined interval in the range from the upper part to the lower part.

As a result, the dew condensation water generated on the outer surface of the glass 13 is attached to the upper portion of the glass 13 to form the strip film 4.
After once forming the water film as a water film in 2, the water film of the water film can be further formed by the band-shaped film 42 attached below the water film, and the water film can be gradually formed from the upper side to the lower side. It becomes possible to reduce the size.

Therefore, the water droplets can be formed into a water film in a stepwise manner, and the water droplets of the dew condensation water are not received by the water receiving portion from between the upper end of the receiving member 16 and the glass 13 but outside the receiving member 16. It becomes possible to avoid leaking to others.

Further, as another embodiment, the hydrophilizing film may be constituted by attaching a plurality of strip-shaped films 43 around the outer surface of the plate glass 22 of the glass 13 as shown in FIG.

As a result, even if the dew condensation water generated on the outer surface of the glass 13 flows downward obliquely due to its own weight, the dew condensation water is received from the lower end of the strip-shaped film 43 attached to the outer surface side portion of the glass 13. You will be able to guide you to Mizube.

In this embodiment, the hydrophilic film 40 is provided on both side plates of the open showcase 1 having an opening on the front surface.
Although the example in which the above is attached is described, the present invention is not limited to this, and the hydrophilic film 40 may be attached to the main body. Further, besides sticking the hydrophilic film 40 only to the open showcase 1 having the opening on the front surface, the same effect can be obtained by sticking it on the glass or the like constituting the upper side wall of the low temperature showcase having the opening on the upper surface.
