Fresh Keeper

Abstract

A fresh keeper used in refrigerating apparatus comprises a lid ( 1 ), an outer drawer ( 2 ) and at least one inner drawer ( 3 ) which is contained in said outer drawer, a gap is formed between the outer drawer and the inner drawer such that said outer drawer ( 2 ), said inner drawer ( 3 ) and said lid ( 1 ) form a sealed space when they are in mounting state. The effect of heat preservation is improved due to the air insulating layer, thereby the temperature inside the fresh keeper is not easily influenced by the ambience and the temperature inside the fresh keeper is more stable. Because of the double-layer structure used in the invention, an air layer is formed. The pressure of the vapor in the air layer is much more than that of the inner drawer, thus it is difficult for the vapor in the inner drawer to diffuse into the air layer, and thereby the moisture in the inner drawer is ensured so that the humidity is kept to be a high value.
