Description

A RICE REFRIGERATOR

The present invention relates to a rice refrigerator, and more specifically, to a rice refrigerator in which cold air from a cooler is filled into an outer case, targets an inner case, and is simultaneously introduced into the inner case through an upper cold air passage to refrigerate grains from the inside and outside, that is, from all sides, thereby thoroughly maintaining the freshness of grains and preventing the occurrence of rice weevils and the like.

In general, grains such as rice, beans, and red beans are difficult to store and cook due to the occurrence of insects, such as rice weevils, depending on temperature and humidity. To prevent this phenomenon, rice containers, or rice refrigerators, are being developed in various ways to maintain appropriate temperature and humidity.
