The white case of Publication No. 192 has an opening in the front half of the top surface that can be opened and closed by a transparent door, a projecting wall in the second half of the top surface with an auxiliary cooler installed on the bottom surface, and a ceiling wall above the projecting wall. A structure is disclosed in which a fluorescent lamp for illuminating the inside of the refrigerator is disposed and a storage part for storing the transparent door when the door is closed.

Moisture in the air outside the rice storage container condenses on the top surface. If the transparent door is opened and closed only a few times, the nil dew may gradually evaporate due to the heat dissipation from the fluorescent lamp, but if the door is opened and closed many times, the amount of condensation will be large. It flows to the front part along the slope, causing internal pressure to drop, or freezing at the front part of the earth surface of the projecting wall, obstructing the opening and closing operations of the transparent door.
