Patent

CA 2579173

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.

L'invention concerne un compartiment fraîcheur, utilisé dans un appareil réfrigérant, comprenant un couvercle (1), un tiroir extérieur (2) et au moins un tiroir intérieur (3) logé dans ce dernier, un espace étant formé entre le tiroir extérieur et le tiroir intérieur de sorte que le tiroir extérieur (2), le tiroir intérieur (3) et le couvercle (1) forment un espace étanchéifié, une fois montés. L'isolation thermique est améliorée grâce à la couche d'air isolante qui limite les influences de l'environnement sur la température à l'intérieur du compartiment et stabilise cette dernière. Une couche d'air est formée grâce à la structure à double couche selon l'invention. Etant donné que la pression de la vapeur dans la couche d'air est supérieure à celle qui règne dans le tiroir intérieur, il est plus difficile pour la vapeur présente dans le tiroir intérieur de diffuser dans la couche d'air, ce qui permet d'obtenir un degré d'humidité élevé dans le tiroir intérieur.
