本発明の湿度調整具の利用法の一つとして青果物の貯蔵
がある。最近各メーカーが家庭用冷蔵庫に野菜専用室を
設け、野菜の鮮度保持に関しての配慮が見受けられる。One of the uses of the humidity regulator of the present invention is the storage of fruits and vegetables. Recently, various manufacturers have installed dedicated vegetable compartments in their home refrigerators, and consideration has been given to maintaining the freshness of vegetables.
しかし家庭用の冷蔵庫では温度の違いが若干あるものの
、野菜専用室として青果物と他の食物とを区別する意味
合いの方が大きい。However, in a home refrigerator, although there is a slight difference in temperature, the purpose of a dedicated vegetable compartment is to distinguish fruit and vegetables from other foods.

が、現行の家庭用冷蔵庫に湿度コントロールの機能を付
茸しようとすると、冷蔵庫が大型化し、家庭用としては
殆ど不適当なものとなる。Humidity control is important for fruits and vegetables, but if you try to add a humidity control function to a current household refrigerator, the refrigerator will become large and almost unsuitable for household use.
そこで容器に水を入れ加湿する方法も考えられるが、場
所をとり、こぼれやすく、青果物に直接水が触れる可能
性があり、結果として直接水に触れ、青果物の腐敗が急
速に進むことになる恐れがある。Therefore, a method of humidifying water in a container can be considered, but it takes up a lot of space, is easily spilled, and there is a possibility that the water may come into direct contact with the fruits and vegetables. There is.
しかるに本発明の水蒸気透過性の材質を用いた湿度調整

ある。However, these drawbacks can be eliminated by using the humidity controller of the present invention made of a material that is permeable to water vapor. In other words, by using the humidity regulator of the present invention, it is possible to provide the humidity necessary to maintain the freshness of fruits and vegetables without directly contacting water. It can also be used indoors.
野菜の保存に関しては透湿度９０〜９５％［ｌＨのもの
が多く、加湿が必要であり、従ってかかる場合本発明の
湿度調整具の内容物は安全性、経済性から水が好ましい
。When preserving vegetables, most of them have a moisture permeability of 90 to 95% [lH, and humidification is necessary. Therefore, in such cases, the content of the humidity adjusting device of the present invention is preferably water from the viewpoint of safety and economy.
