So far most of the attention has been aimed at controlling just the temperature of the refrigerators; there are not a method and a device keeping fresh by controlling the humidity.
Some sealed material are used in the sealed box while the sealed box could not well prevent water from diffusing, because the vapor pressure of air in the box forces the humidity in the box to balance with that of ambience through a small aperture, therefore water would diffuse quic

Embodiment Construction

[0038]The fresh keeper shown in FIG. 1 consists of a lid 1, an outer drawer 2 and an inner drawer 3. The inner drawer 3 could be several drawers in which different foods may be put. The inner drawer 3 is smaller than the outer drawer by a predetermined size. When the inner drawer 3 is put into the outer drawer 2, the lid 1 is installed on the outer drawer 2, a front wall 4 of the inner drawer 3 lies against two sidewalls, a bottom and the lid 1 of the outer drawer 2, thereby a sealed space is formed inside the inner drawer 3. At least one protrusion 5 is provided in the sidewalls and the bottom of the inner drawer 3, when the inner drawer 3 is set in the outer drawer 2, a desired distance is kept between the inner drawer 3 and the outer drawer 2 due to the protrusion 5, thus an air insulation is formed between the inner drawer 3 and the outer drawer 2, as shown in FIG. 2, the protrusions 5 could also be provided on the sidewall and the bottom of the outer drawer 2. The gap of the ai...

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.

Description

TECHNICAL FIELD[0001]The invention relates to a fresh keeper. More particularly, the invention relates to a fresh keeper used in refrigerating apparatus.BACKGROUND ART[0002]The two most important factors affecting the shelf-life of refrigerated food are temperature and humidity. So far most of the attention has been aimed at controlling just the temperature of the refrigerators; there are not a method and a device keeping fresh by controlling the humidity.[0003]Several fresh keepers have been used in refrigerating apparatus. A kind of fresh keeper is widely used at present. This fresh keeper consists of a simple single-layer drawer which was not sealed well, thus the temperature in the drawer is not stable and water diffuses quickly while the temperature and the humidity of ambience and their variation have influence on those inside the drawer, thereby the food contained in the drawer is easy to perish or dehydrate.[0004]A kind of sealed box is also used to keep fresh. Some sealed m...
