Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vegetable storage container for a refrigerator for preserving vegetables in a fresh state for a long period of time.

BACKGROUND OF THE INVENTION Conventionally, vegetable storage containers in refrigerators have been designed to preserve vegetables for a long period of time by improving airtightness. An example of a conventional vegetable storage container for a refrigerator will be described below with reference to the drawings. FIG. 4 is a sectional view of a main part showing a state in which a vegetable storage container of a conventional refrigerator is installed. A refrigerator main body 1 has a door 2 disposed on the front, and a vegetable storage container 3 whose top surface is open is disposed at the bottom. The upper opening surface of the vegetable storage container 3 has a glass lid 5 around which a rubber gasket is arranged. The refrigerator main body 1 is made up of an outer box 6, an inner box 7, and a urethane insulation material 8 injected with foam into the space of the box, and the door 2 is made up of an outer box 6', an urethane insulation material 8', and an inner frame 9.
and a shelf 10 disposed on the inner frame 9, and further includes the door 2.
A sealing gasket 11 is arranged around the . The vegetable storage container 3 is located in the refrigerator compartment 1 of the refrigerator main body 1.
When stored in the lower part of 2, the upper opening surface is completely sealed by a glass lid 6 around which a rubber gasket 4 is arranged. Therefore, it has been devised to prevent the stored vegetables 13 from drying out and withering, so that the vegetables 13 can be stored for a long period of time.

Problems to be Solved by the Invention However, since the above-mentioned structure had a completely sealed structure, a large amount of water from vegetables, especially leafy vegetables, condensed and adhered to the inner surface of the lid S. . This means that the vegetable storage container 3 is placed at the bottom of the refrigerator compartment 12, and one cold vegetable is stored in one container.
This is because the cold air inside the container 2 cools the outer surface of the lid 5, while the temperature inside the vegetable storage container 3 is high due to the heat of respiration of the vegetables 13, creating a temperature difference on the surface of the lid 5. A large amount of water droplets adhering to the lid body 5 fall by natural fall or due to vibrations when the vegetable storage container 3 is attached and removed, and accumulate on the surface of the stored vegetables 13 and the bottom of the vegetable storage container 3. . Therefore, for the first few days of storage, the vegetables 13 are prevented from drying out and thus remain fresh, but as described above, the vegetables 13 are damaged and rotten due to accumulated water. Was.

In view of the above problems, the present invention provides a vegetable storage container for a refrigerator that does not cause dew condensation on the lid and allows vegetables to be stored 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 includes a container with an open top surface, a moisture permeable membrane mainly composed of 5 thin hydrophobic resin films, and a large number of components. It is composed of a resin flat plate having a through hole, the moisture permeable membrane, and the flat plate, and the upper opening of the container (with a closely-closed lid body and a large viewing area provided inside the container) is cut out. It is something.

Effects of the present invention With the above-described configuration, the vegetable storage container does not allow direct intrusion of cold air, and the inside of the container is kept at high humidity by moisture evaporated from the vegetables themselves, so that drying is suppressed, and
The humidity inside the container is made uniform by the appearance provided inside the container, and excess moisture is efficiently released outside the container through the moisture permeable membrane, so there is no condensation on the lid and damage caused by water droplets. You can keep vegetables fresh.

EXAMPLE Hereinafter, a vegetable storage container for a refrigerator according to an embodiment of the present invention will be described with reference to the drawings. Components that are the same as those of the conventional example are given the same numbers and their explanations will be omitted.

In FIGS. 1 to 3, 14 indicates a lid 1 at the top opening.
6 is a tightly closed vegetable storage container. The lid body 15 is
A flat plate 16 made of an olefin thermoplastic resin such as polyethylene or polypropylene and having a large number of through holes, a moisture permeable membrane 17 welded to one side of the flat plate 16, and a moisture permeable membrane 17 disposed around the outer periphery of the flat plate 16 having the through holes. A packing 16' made of rubber such as vinyl chloride is provided. When the vegetable storage container 14 is stored in a predetermined position at the lower part of the refrigerator compartment 12 of the refrigerator body, the lid 1 has a rubber gasket 16' around the outer periphery.
It is detachably arranged so as to be in close contact with 5. Also 2
Reference numeral 3 indicates a large viewing area provided on the back surface of the vegetable storage container 14. In addition, the vegetable storage container 14 has a first cold air convection 21 that flows through the upper part of the lid body 15 from the rear surface to the front, among the cold air from a control panel (not shown) provided at the upper rear surface of the refrigerator compartment 12. and the inner surface of the vegetable container 14,
It is cooled to a predetermined temperature by the second cold air convection 22 that passes through the bottom surface to the front surface.

Here, the moisture permeable membrane 17 will be explained. The moisture permeable membrane 1
7 is a lamination of a silicon thin film 18 and a nylon fiber 19. The silicon thin film 18 has a thickness of about 10 μm to about 50 μm, and is composed of an aggregate of mostly amorphous chain molecules. The cluster completely shuts out liquid and has gas permeability due to 10 to 103 molecular gaps. In other words, water vapor, air, and carbon dioxide gas are permeable if there is a difference in concentration between the inside and outside of the membrane.

With the above configuration, there is no direct intrusion of cold air into the vegetable storage container 14, and the container 14 is kept at high humidity due to moisture evaporated from the vegetables 13 stored in the vegetable storage container 14. . On the other hand, due to the first cold air convection 21 and the second cold air convection 22 that cool the vegetable storage container 14, the temperature distribution inside the vegetable storage container 14 is lower at the back and gradually increases toward the front. Although this phenomenon may easily cause dew condensation on the inner surface of the lid 15, the air inside the container is stirred by the aperture 23 provided on the inner surface of the vegetable storage container 14, and the temperature distribution is made uniform.

In other words, the relative humidity is likely to be equalized, and the moisture above the saturated humidity is removed from the refrigerator compartment 12, which has a low humidity, through the moisture permeation and the dehumidifying action of the refrigerator cooler (not shown) through the membrane 17. Since moisture permeates efficiently toward the sides, no condensation occurs on the lid 15. Therefore, since water droplets do not fall and accumulate on the surface of the vegetables 13 or the bottom of the vegetable storage container 14, the stored vegetables 13 are prevented from drying out and shriveling, and can be stored fresh without being damaged by water droplets. can.

In the above embodiment, the silicon thin film 18 may be a microporous film made of Teflon or polyurethane, which also has moisture permeability.

Effects of the Invention As described above, the present invention provides a container with an open top surface, a moisture permeable membrane mainly composed of a hydrophobic resin thin film, a resin flat plate having a large number of through holes, and the moisture permeable membrane and the flat plate. The vegetable storage container is composed of a lid that is in close contact with the top opening of the container, and a large opening provided in the container, so that the vegetable storage container does not allow direct intrusion of cold air, and the fresh vegetables stored inside the container are protected. The moisture that evaporates from the vegetables themselves keeps the inside of the container at high humidity, which suppresses dryness and shrinkage. Since the water is efficiently discharged outside the container through the membrane, there is no condensation on the lid, and the vegetables can be kept fresh without any damage to the vegetables due to falling water droplets.
