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. 6 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 6 around which a rubber gasket is arranged. The refrigerator body 1 is made up of an outer box 6, an inner box 7, and a urethane heat insulating material 8 injected with foam into the space of the box.
and a shelf 10 disposed in the inner frame 9, and further includes a shelf 10 disposed in the inner frame 9, and
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 5 around which a rubber gasket 4 is arranged. Therefore, it has been devised to prevent the stored vegetables 13 from drying and shriveling so that the vegetables 13 can be stored for a long period of time.

Problems to be Solved by the Invention However, in the above structure, since the structure was completely sealed, a large amount of water that evaporated from leafy vegetables condensed and adhered to the inner surface of the lid body 5. . This is because the vegetable storage container 3 is located at the bottom of the refrigerator compartment 12, and the vegetable storage container 3 is located at the bottom of the refrigerator compartment 12.
This is because the cold air inside cools the outer surface of the lid 5, while the temperature inside the vegetable storage container B3 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 5 fall due to natural fall or vibrations when the vegetable storage container 3 is attached and removed, and accumulate on the surface of the stored vegetables 130 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 for a refrigerator of the present invention has a container with an open top surface, a moisture permeable membrane mainly composed of a hydrophobic resin thin film, and a large number of through holes. A lid body is provided in close contact with the upper opening of the container, and a part of the container is constructed of a hydrophilic porous resin plate.

Effects of the present invention With the above-described configuration, the vegetable storage container does not allow direct penetration 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
Excess water is efficiently released outside the container through the moisture-permeable membrane, so no condensation occurs on the lid, and condensed water that temporarily adheres to the inside of the container is also released through the hydrophilic porous resin plate. Since the water is released outside the container, vegetables can be kept fresh without being damaged by water droplets.

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 in the conventional example are given the same numbers, and their explanations will be omitted.

In FIGS. 1 to 4, 14 indicates a lid 1 at the top opening.
6 is a tightly closed vegetable storage container. The lid 16 includes 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 the flat plate 16 having the through holes. A rubber gasket 16' made of vinyl chloride or the like is arranged around the outer periphery of the gasket. When the vegetable storage container 14 is stored in a predetermined position in the lower part of the refrigerator compartment of the refrigerator main body 1, the vegetable storage container 14 is brought into close contact with the lid body 15 having a rubber gasket 16' on the outer periphery. It is arranged so that it can be attached and detached at will. In addition, the vegetable container 14 receives cold air from the lid body 1 from a control panel (not shown) provided at the upper part of the rear surface of the refrigerator compartment 12.
The vegetable container 14 is cooled to a predetermined temperature by a first cold air convection 21 flowing through the upper part of the vegetable container 14 from the back surface to the front, and a second cold air convection 22 passing through the back surface and the bottom surface of the vegetable container 14 to the front.

Reference numeral 23 is a plate made of a hydrophilic porous resin (hereinafter referred to as the hydrophilic porous resin plate 23) and is attached to cover a through hole provided in the bottom of the vegetable storage container 14.

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 1E1 has a thickness of about 10 μm to about 60 μm, and is mostly composed of amorphous chain-like molecular aggregates. It completely shuts out liquid and has gas permeability due to the molecular spacing of 10 to 105. In other words, water vapor, air, carbon dioxide gas,
It has the property of being permeated if there is a difference in concentration between the inside and outside of the membrane.

Next, the hydrophilic porous resin plate 23 will be explained.

The hydrophilic porous resin plate 23 is made up of fine pores that are invisible to the naked eye, has low gas permeability, and is hydrophilic, allowing liquids such as water to pass through the pores to the other side by capillary action. It is moist.

With the above configuration, there is no direct intrusion of cold air into the vegetable storage container 14, and the interior of the container 14 is kept at high humidity due to moisture evaporated from the vegetables 13 stored in the vegetable storage container 14. . Moisture with a humidity higher than the saturated humidity permeates through the moisture permeable membrane 17 to the refrigerator 12 side where the humidity is low due to the dehumidifying action of the cooler (not shown) of the refrigerator. That is, even if the lid 16 is cooled by the first cold air convection 21 that cools the vegetable storage container 14, no condensation will occur on the lid 16 due to the moisture permeability of the moisture permeable membrane 17. Furthermore, due to the second cold air convection 22 that cools the vegetable storage container 14, the temperature distribution inside the vegetable container 4 is lower at the inner surface, and when a large number of vegetables 13 are stored, dew condenses on the inner surface of the container 14. However, this condensed water moves to the bottom surface due to gravity and is discharged to the outside of the refrigerator via the hydrophilic porous resin plate 23 provided on the bottom surface.

Therefore, water droplets do not fall from the lid body 16 or water remains on the bottom surface, and the stored vegetables 13 are prevented from drying out and shriveling, and are not damaged by water droplets, and can be stored fresh. .

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 constructed of a lid that is in close contact with the top opening of the container, and a portion of the container is made of a hydrophilic porous resin plate, so that the vegetable storage container is protected from direct intrusion of cold air. The moisture that evaporates from the fresh vegetables stored inside the container keeps the inside of the container at high humidity, suppressing dryness and shrinkage, and the moisture permeable membrane and hydrophilic porous resin plate prevent condensation and Since there is no water puddle on the bottom, the vegetables can be kept fresh without being damaged by water droplets.
