PURPOSE: The bottom part of chiller is projected to the lower part of diaphragm. In case the moisture is created within chiller, while not being touched with the grains of the grain store part, the moisture is exhausted. CONSTITUTION: A grain refrigerator comprises a partition(109), a grain storage(105), and a cooling unit(130). It is composed of the diaphragm The partition is installed inside a housing(102). In the grain store part, the grain is saved on the inner structure of housing and the top of partition. The bottom part of chiller is downwardly protruded from the lower-part of partition. The top end portion of cooling unit locates in the grain store part. The grain of the grain store part is cooled. The cryostat is formed into the far infrared rays emitter including the yellow soil. In the wall of cryostat, layer is formed in which the water is unable to be passed through and which. The layer is formed with the glazing.본 발명은 내부에 증발기가 설치되는 곡물 냉장고의 냉각장치의 내부에 습기가 곡물 저장부에 유출되지 않도록 하면서도 냉각장치의 내부의 습기를 곡물 저장부의 외측으로 안전하게 유출할 수 있도록 한 곡물 냉장고와, 이러한 곡물 냉장고의 냉매를 공용으로 사용할 수 있도록 한 정수기 겸용 곡물 냉장고이다.
