Description

Description: FIELD OF THE INVENTION The present invention relates to a vegetable storage container of a refrigerator for storing vegetables in a fresh state for a long period of time.

2. Description of the Related Art Conventionally, a vegetable storage container of a refrigerator is made to store vegetables for a long time by improving hermeticity. Hereinafter, an example of a vegetable storage container of a conventional refrigerator will be described with reference to the drawings. FIG. 4 is a cross-sectional view of a main part showing a mounted state of a vegetable storage container of a conventional refrigerator. Refrigerator body 1
Has a vegetable storage container 3 having a door 2 disposed on the front surface and an open top surface at the bottom. On the upper opening surface of the vegetable storage container 3, a glass lid 5 around which rubber packing is disposed is provided. The refrigerator body 1 includes an outer box 6 and an inner box 7.
The door 2 comprises an outer box 6 ′, a urethane insulating material 8 ′, an inner frame 9, and a shelf 10 disposed in the inner frame 9. And the door 2
A seal packing 11 is provided in the vicinity of the. Then, the vegetable storage container 3 is placed in the refrigerator compartment 12 of the refrigerator body 1.
When stored in the lower part, the upper opening surface was completely sealed by the glass lid 5 around which the rubber packing 4 was disposed. Therefore, it has been devised that the stored vegetables 13 are prevented from drying and shrinking, and the vegetables 13 can be stored for a long time.

Problems to be Solved by the Invention However, in the above-described configuration, since water is completely evaporated from vegetables, especially leafy vegetables, a large amount of water condenses on the inner surface of the lid 5 and adheres to the lid 5 because of the completely closed structure. This is because the vegetable storage container 3 is located at the bottom of the refrigerator compartment 12, and the cold air in the refrigerator compartment 12 cools the outer surface of the lid 5, while the vegetable storage container 3 has the respiration heat of the vegetables 13. This is because the temperature is high and a temperature difference occurs on the surface of the lid 5. And the lid 5
A large amount of water droplets adhered to the container 13 fall naturally or fall due to vibrations when attaching or detaching the vegetable storage container 3, and accumulate on the surface of the stored vegetables 13 or the bottom surface of the vegetable storage container 3. Therefore, during the first few days of storage, the vegetables 13 are kept fresh because the drying is prevented, but during that time the vegetables 13 are damaged by the accumulated water as described above, and it is said that the vegetables 13 become slimy. There was a problem. Therefore, the period for keeping vegetables fresh was not so long. If you store additional vegetables (especially leafy vegetables), especially when you have already stored vegetables for several days, the water that has transpired from the new vegetables will damage the previously stored vegetables rapidly and rot. There was a problem that.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a vegetable storage container of a refrigerator capable of removing dew condensation water attached to a lid and storing vegetables for a long period of time.

Means for Solving the Problems In order to solve the above problems, the vegetable storage container of the refrigerator of the present invention is configured such that a lid made of a non-woven fabric obtained by press-molding long fibers of polyethylene is in close contact with the upper opening of the container. It is provided.

Action The present invention, by the above-described configuration, prevents the water vapor generated by the transpiration or respiration from the stored vegetables from condensing on the surface of the lid of the container and appropriately drying the vegetables in the container. And preserve the vegetables for a long time.

Embodiment A vegetable storage container of a refrigerator according to one embodiment of the present invention will be described below with reference to the drawings. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

Reference numeral 14 denotes a vegetable storage container in which the lid 15 is closely attached to the upper opening. The lid 15 includes a flat plate 16 having a large number of through holes made of an olefin-based thermoplastic resin such as polyethylene or polypropylene, and a nonwoven fabric 17 welded to one surface of the flat plate 16.
And a rubber packing 16 ′ made of vinyl chloride or the like disposed around the outer periphery of the flat plate 16 having the through hole. And the vegetable storage container 14 is provided with the refrigerator main body 1.
At a predetermined position below the refrigerator compartment 12, when the vegetable storage container 14 is stored, it is detachably disposed so as to be in close contact with the lid 15 having a rubber packing 16 'around the outside. Here, the nonwoven fabric 17 will be described. The non-woven fabric 17
Is formed by pressing a long fiber of polyethylene by hot pressing or the like.
On the surface, a polyethylene film layer 19 having fine pores formed by melting a part of the polyethylene long fiber layer 18 is formed. The long fiber layer 18 of polyethylene has a dense structure and the pores of the polyethylene film layer 19 on the surface are so fine that a liquid such as water does not easily pass therethrough, but water vapor, air, carbon dioxide gas, etc. When there is a density difference, the light is transmitted.

With the above configuration, there is no direct entry of cold air into the vegetable storage container 14, and the moisture inside the container 14 is kept high by the moisture evaporated from the vegetables 13 stored in the vegetable storage container 14. . And if the inside of the container becomes unnecessarily humid,
Through the non-woven fabric 17 on the surface of the lid 15 that is most likely to be cooled by facing the refrigerating room 12 and being cooled well, moisture is gradually transmitted to the refrigerating room 12 having low humidity as indicated by an arrow.

And by making the area of this nonwoven fabric appropriate,
It can be kept at 80-95% RH, which is said to be suitable for storing vegetables, and the top surface of the lid and vegetable storage container
Water droplets fall down because there is no condensation inside the vegetables 13
Surface and the bottom of the vegetable storage container 14, so that the stored vegetables 13 are prevented from drying and shrinking, and are not damaged by water points and become slimy, Vegetables 13 for even longer periods
In particular, leaf vegetables such as spinach can be stored in a fresh state.

Effect of the Invention As described above, the vegetable storage container of the refrigerator of the present invention is provided with a lid made of a nonwoven fabric formed by press-molding long fibers of polyethylene, which is provided in close contact with the upper opening of the container. The storage container has no direct entry of cold air, the inside of the container is kept at a high humidity by the moisture evaporating from the fresh vegetables stored therein, and since the water droplets from the lid do not fall, Since dry atrophy can be suppressed and water damage can be avoided, freshness of fresh vegetables can be maintained for a long time.

In addition, since the fibrous resin is compacted, the manufacturing process can be simplified, so that the material cost can be reduced.
