Definitions
- the invention relates to a fresh keeper. More particularly, the invention relates to a fresh keeper used in refrigerating apparatus.
- a kind of sealed box is also used to keep fresh. 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 quickly and the temperature would not be stable if there is even a small aperture, even if the food is stored in a sealed box.
- the prior device keeping fresh above can not provide stable humidity and temperature which is useful to keep vegetable and fruits fresh.
- the object of the invention is to provide a fresh keeper which can ensure stable temperature and higher humidity thereof, therefore the invention could prevent the water contained in the food from diffusing.

- a portion engaged with the supporting part of the refrigerating apparatus is provided outside said outer drawer so that said fresh keeper could be put into the refrigerating apparatus slidablely.
- the invention as compared with the prior art has following advantages:
- the fresh keeper is equivalent to be thickened due to the air isolating layer in the invention so that the effect of heat preservation is improved, thereby the temperature inside the fresh keeper is not easily influenced by ambience, and the temperature inside the fresh keeper is more stable.
- an air layer is formed.
- the pressure of the vapor in the air layer is much more than that in 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 therein is kept to be a higher value.
- Figure 1 is an exploded view of the fresh keeper according to the first embodiment of the invention
- Figure 2 is a sectional view of the fresh keeper in figure 1 , in the tightly engaged state
- Figure 3 is an exploded view of the fresh keeper according to the second embodiment of the invention.

- Figure 7 is a sectional view of the fresh keeper in figure 6, in the tightly engaged state
- Figure 8 is an exploded view of the fresh keeper according to the forth embodiment of the invention.
- Figure 9 is a sectional view of the fresh keeper in figure 8, in the tightly engaged state
- Figure 10 is a sectional view taken along line B-B in figure 9;
- Figure 11 is a graph showing the comparison between the variation of the relative humidity in the fresh keeper of the invention and that in the vegetable drawer of prior art;
- Figure 12 is a graph showing the comparison between the variation of the temperature in the fresh keeper of the invention and that in the vegetable drawer of prior art.
- the fresh keeper shown in figure 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.
- 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 figure 2, the protrusions 5 could also be provided on the sidewall and the bottom of the outer drawer 2.
- the gap of the air insulation between the inner drawer 3 and the outer drawer 2 is 5mm-30mm because of the difference of their sizes.
- the gap is 10mm.
- the front 4 of the inner drawer is double-layer.
- a flange 6 may be provided in the predetermined position of the two sidewalls and the back of the inner drawer 3, the flange 6 is preferably provided on the top, as shown in figure 3, thus a desired distance exists between the sidewalls and the back of the outer drawer 2 and those of inner drawer 3; preferably, two integrated guides 8 are provided on the edge of the bottom of the inner drawer 2, as shown in figure 5, thus the inner drawer 3 is supported on the integrated guides 8 of the outer drawer 2, when the fresh keeper is in close state, a desired distance exists between the bottom of the inner drawer and that of the outer drawer, as shown in figure 4.
- an outer drawer 2 having four sidewalls and a bottom, and a inner drawer 3 having four sidewalls and a bottom could also be used, the inner drawer 3 could be put into the outer drawer 2 directly, a cylindrical portion 7 is provided on the bottom of said inner drawer 3, the cylindrical portion 7 could also be provided in the corresponding position inside said outer drawer 2, therefore a desired distance exists between the bottom of the inner drawer and that of the outer drawer.
- a flange 6 could be provided at predetermined position in the four sidewalls of the inner drawer 3, the flange is preferably set on the top, as shown in figures 6 and 7, therefore a desired distance exists between the sidewalls of the inner drawer 3 and those of the outer drawer 2 when the inner drawer 3 is put into the outer drawer 2.
- the distance between the sidewalls and the bottoms of the two drawers forms an air isolating layer.
- a sealed space is formed inside.
- a handle may be provided on the lid 1 to facilitate to open/close the lid 1.
