Therefore, parts such as partition plate 9, middle partition 10, frame 13, lid 14 are required,
It had a problem that it had a complicated structure and could not be applied to a 1-door or 2-door refrigerator.

In view of the above problems, it is an object of the present invention to provide a vegetable storage container that can store vegetables for a long time in one door, two doors or a storage room.

Means for Solving the Problems In order to solve the above problems, the vegetable storage container of the refrigerator of the present invention is provided with a lid body that is in close contact with the opening, and a through hole provided in a dish-shaped recess on the bottom surface of the lid body. The inner surface of the hole, which is welded over the entire circumference of the through hole, is located on the container side at the bottom and has a hydrophilic fiber on the inner surface, and the outer surface has a water-repellent moisture permeable membrane fixed thereto, and a recess is formed on the top. In addition to providing a flat plate to cover, a cold air flow inlet formed on the rear wall surface of the air passage formed by the bottom of the lid and the top plate, and a cold air flow outlet formed by the flat plate and the lid on the front of the air passage. The configuration is provided.

Action The present invention has a structure in which a lid is provided on a shelf formed in an inner box, and a container is provided near the lower part of the shelf so that vegetables can be stored for a long period of time. Further, since the projecting ribs are provided on the outer circumference of a large number of through holes provided on the bottom surface of the lid body, the specification is such that the juice of food that falls along the flat plate does not adhere to the moisture permeable membrane.

Example Hereinafter, a vegetable storage container for a refrigerator according to an example of the present invention will be described with reference to the drawings. The same components as those in the conventional example are designated by the same reference numerals, and the description thereof will be omitted.

Reference numeral 19 is a refrigerating room, and 20 is a vegetable storage container in which a lid 21 is closely attached to the upper opening. The lid 21 has a dish-shaped central portion,
A large number of through holes 21b are provided in the bottom part 21a, and the moisture permeable film 22 is welded over the entire surface of the through holes. A packing 23 is fitted on the lower front surface of the lid 21, and a flat plate 24 is provided on the top.
Is provided and forms a space with the bottom portion 21a. Several protruding ribs 21c are provided on the upper front surface of the lid body 21,
The flat plate 24 is supported and the opening area of the front surface is secured.

A vent 21d is provided on the rear wall surface of the lid 21, and a vent 21f is provided on the rear protrusion 21e of the lid 21.

Further, a rib 21g having a height of several millimeters is provided all around the outer periphery of the moisture permeable membrane 22 provided on the lid bottom portion 21a, and moisture and food transmitted from the flat plate 24 and falling to the lid bottom portion 21a are used. The soup is attached to the moisture permeable membrane 22 so that the moisture permeable effect is not lost.

Further, the lid body 21 is supported by projecting walls 25 from both side walls of the inner box 15, and is detachably arranged in a gap with the upper wall 25a. The vegetable storage container 20 is supported by a lower projecting wall 25b in the vicinity of the lid body 21, and the lid body 21, the projecting wall 25, and the upper projecting wall 2 are provided.
5a, the space between the vegetable storage container 20 and the protruding wall 25 is kept to a minimum to ensure hermeticity.

When the vegetable storage container 20 is stored at a predetermined position under the refrigerating chamber 19 of the refrigerating main body 1, the vegetable storing container 20 is detachably arranged near the lid 21.

Here, the moisture permeable membrane 22 will be described. The moisture permeable membrane 22
Is a laminate of a silicon thin film 26 and a hydrophilic nylon fiber 27. The silicon thin film 26 is a thin film of about 10 μ to about 50 μ and is composed of almost amorphous lump-like molecular aggregates. Shut out completely,
It has gas permeability with a molecular spacing of 10 to 10 ³ Å. That is, water vapor, air, and carbon dioxide are permeated if there is a difference in concentration inside and outside the membrane. Further, the hydrophilic nylon fiber 26 is used as described above in order to prevent dew condensation.

With the above-mentioned configuration, the vegetable storage container 20 has the moisture permeable membrane 22 so that cold air does not directly enter the vegetable storage container 20 and the vegetable storage container 20 is formed by the water evaporated from the vegetables 28.
The inside is kept in high humidity. Then, as shown in FIG. 4, water having a saturated humidity or higher gradually permeates through the moisture-permeable film 22 to the refrigerating chamber 19 side having low humidity as shown by an arrow. Therefore, since water droplets do not adhere to the moisture permeable membrane 22, the water droplets do not fall and collect on the surface of the vegetables 28 or the bottom surface of the vegetable storage container 20, so that the stored vegetables 28 are prevented from drying and shrinking. At the same time, it is possible to store vegetables 28, especially leafy vegetables such as spinach, in a fresh state for a longer period of time than before without being damaged by water drops and becoming slimy. According to the experimental results, the vegetable storage container 20 can be obtained by selecting an appropriate moisture-permeable amount of the moisture-permeable film 22.
The inside can be kept at a humidity of 80 to 90% RH, which is said to be suitable for storing vegetables.

Further, the moisture permeated from the moisture permeable membrane 22 is collected in the space of the flat plate 24 and the bottom portion 21a of the lid body 21, but is shown by an arrow in FIG. 1 passing through the rear ventilation hole 21f of the lid body 21 and the rear wall surface ventilation hole 21d. The cold air in the refrigerating compartment 19 shown in this figure causes the air to flow into the refrigerating compartment 19 through the front surface of the lid 21 and the opening of the flat plate 24, so that water droplets or dew condensation does not adhere to the lower surface of the flat plate 24. Since the lid 21 is dish-shaped, the lid 21
The entire circumference of 21 becomes structurally strong, and it is possible to easily form a ventilation hole with the flat plate 24.Because the moisture permeable membrane 22 is insert-molded into an integrated structure, the number of parts is small, It can be easily attached to and detached from the refrigerator compartment 19 and has good cleanability.

EFFECTS OF THE INVENTION As described above, the vegetable storage container of the refrigerator of the present invention includes a lid body that is in close contact with the upper opening, a through hole provided in a dish-shaped recess on the bottom surface of the lid body, and the entire circumference of the through hole portion. A space is formed by providing a moisture permeable membrane welded over the top and a flat plate on the top of the lid, and the moisture permeable membrane has a hydrophilic fiber on the inner surface located on the container side and a hydrophobic surface on the flat plate side. Since it is a wet film and the lid is provided on the protruding wall formed in the inner box, and the vegetable storage container is provided in the vicinity of the lower portion of the lid, the hermeticity is maintained and the vegetables can be stored for a long period of time. In addition, since protruding ribs are provided on the outer periphery of many through holes provided on the bottom surface of the lid, it is possible to prevent the juice of food that falls along the flat plate from adhering to the moisture permeable membrane and maintain the moisture permeability effect. effective.
