Description

[Detailed description of the invention] <Industrial use! ? 〉 The present invention provides a storage structure 1 that can exterminate aerobic insects and bacteria.
For example, it relates to chests of drawers, cupboards, clothes boxes, etc.

BACKGROUND TECHNOLOGY In conventional storage structures of this type, such as wardrobes, there are many cases in which the clothes stored therein become unusable due to insect damage.

For this reason, conventional methods have been to air the stored clothes to dry them to exterminate the insects on the clothes, or to seal sublimation insect repellents such as naphthalene in the drawer to prevent insects from attracting insects at night due to its medicinal properties. There is.

<Problems to be Solved by the Invention> Among these conventional methods of preventing insects, using insect drying has the inconvenience of having to decide the last period of execution depending on the weather, as well as being laborious and causing problems with clothing. The problem is that it requires a large space to develop, making it difficult for families in today's society to implement it.

On the other hand, when using insect repellents, the above-mentioned problem of drying insects can be solved, but since the insect repellents do not have insecticidal effects, complete insect repellent effects cannot be obtained, and clothes may get smelly or dry. There is a problem that the insect repellent may change color, and since the insect repellent is a consumable item, it is inevitable to forget to refill the drawer, resulting in unexpected damage.

Means for Solving the Problems〉 The storage structure of the present invention, as shown in FIG.
The air inside the exterior body 10 is brought into an oxygen-depleted state using

Because of this, I am deficient in oxygen! 120 is provided with a gas separator 22 configured using a gas separator 11921 that separates oxygen. Or air is supplied from both sides.

The gas separator 22 further includes a non-permeable gas extraction piping system 40.
and a permeate gas extraction piping system 50, from one of which an oxygen-enriched gas is removed, and from the other an oxygen-depleted gas.

Of the two pipe systems mentioned above, the pipe system for taking out the oxygen-enriched gas opens to the outside of the exterior body, and the other opens to the storage space, so that the oxygen-enriched gas is discharged outside the exterior body, while The depleted gas is discharged into the storage space 12.

The exterior body 10 is hermetically sealed to keep the air inside oxygen-deficient, but it is configured to be openable at any time, and when opened, the contents inside can be taken out.

Effect> Since the structure of the present invention is as described above, the interior of the exterior body 1O is filled with oxygen-depleted air, which is caused by oxygen depletion +z1
20 operations. As a result, the inside of the exterior body 10 becomes deficient in oxygen to the extent that organisms that require oxygen as a survival condition cannot survive therein.

Embodiment FIG. 1 is a partially cutaway front view of the storage structure of the present invention. In this embodiment, the exterior body 10 is made into a wardrobe, and an oxygen depletion device 20 is provided inside.

The exterior body IO has a storage space 12 sealed with a door 11, and oxygen in this space 12 is depleted by an oxygen depletion device 20.

The oxygen deficiency device 20 is configured to use a gas separation membrane 21 that separates oxygen to discharge the separated oxygen to the outside of the storage space 12 and to discharge the oxygen-deficient gas after the oxygen has been separated into the storage space 12. It is.

In the example, in the above gas separation [I21, the permeation rate is H2
o > co, 2) O > co≧N is used, and such a gas separation membrane includes "Hisep" (registered trademark) manufactured by Asahi Glass Co., Ltd.

The gas separation membrane 21 is housed in a gas separator 22, and a gas supply pipe system 3 is provided on the gas supply side of the gas separator 22.
0 and 111JI for gas! A non-permeable gas take-off pipe system 40 that does not pass through is connected to the gas separator 22, and a permeate gas take-off pipe system 50 is connected to the gas permeable side of the gas separator 22.

The gas separator 22 differs depending on the structure of the gas separation membrane 21, and the current structure of the gas component II membrane 21 is classified into flat membrane modules, hollow modules, spiral modules, etc.

The gas separation membrane 21 is set with a pressure difference such that the gas supply side is at a high pressure so that gas can pass through the membrane.
For this purpose, the permeated gas pressure applying means 1 is provided with, for example, a blower fan 61 located on the gas supply side and a vacuum pump 62 located on the gas permeation side.

The gas supply pipe system 30 is configured to suck in air from inside the drawer and/or from outside the drawer and feed it to the gas separator 22.

The embodiment shown in FIGS. 1 and 2 is provided with an intake port 31 that opens to the outside of the wardrobe.

The gas separation membrane 21 has a property of separating oxygen o2, and in the embodiment, the gas separation membrane 21 has a property of separating oxygen o2, and in the embodiment, the pressure difference set by the permeation gas pressure applying means is 120. Pass through CO2, 02L
It is determined that the filter is separated into the non-transparent side.

Since the non-permeable side of the gas separation membrane 21 becomes oxygen-enriched gas, the non-permeable gas take-off pipe system 40 has an exhaust port 41 that opens outside the drawer. It is reconstituted in a room with a chest of drawers.

On the other hand, the permeated gas extraction pipe system 50 uses a suspension rod as an exhaust port 51, and the H2O is emitted from the pipe system 50, for example.

It is configured to exhaust CO2-enriched air into the drawer, and for this purpose, the hanging rod has many exhaust holes 511.

In the storage structure of the present invention, the storage space 12 is filled with air depleted in oxygen by the oxygen depletion device 20 in this way.

As a result, the insects parasitic on the clothes 70 become deprived of oxygen and die, thereby exterminating the insects.

In other words, pests that attach to clothing have an oxygen concentration of 3 to 5% higher than that of the atmosphere.
This is because if the oxygen content is lowered, they will die in a short period of time, so by maintaining such an oxygen-deficient state, it is possible to quickly reduce the activity of insect pests and gradually kill them.

This oxygen-depleted air can be used in cupboards and clothing boxes, and in addition to suppressing the growth of aerobic bacteria in cupboards, it can also be used to exhaust oxygen-enriched gas obtained from an oxygen-deficient device into the room. It can also be used for fermentation by aerobic microorganisms.

In the above, one storage structure of the present invention can also be constructed as follows.

As the gas separation membrane 21, the Hysep (registered trademark)
When using a permeate gas pressure, one cup is produced in which oxygen 02 is permeated while nitrogen N2 is obtained as a non-permeable gas.

In this case, as shown in FIG.
This means that the H2O and CO2 components are exhausted to the outside of the drawer along with oxygen, thereby lowering the humidity inside the drawer.

Next, the gas supply pipe system 30 may take in the air in the drawer, and in this case, as shown in FIG. 4, the permeated gas containing the C02 component is exhausted into the drawer; Although there are cases where the non-permeable gas containing the N2 component is exhausted into the tank, the oxygen depletion of the storage space 12 can be increased in either case.

In the above embodiment, the oxygen depletion device 20 is built into the chest of drawers, but as shown in FIG. 6, it may be configured separately from the exterior body 10 so that it can be attached to and removed from the exterior body 10 at any time. In this way, one oxygen depletion device 20 can be used for a large number of exterior bodies 10.

As shown in FIG.
3, and each pipe system 30, 40.50 may be connected to the intake port 31° and the exhaust port 41.51 at joints 32, 42, 52, respectively. It can be detachably set inside the exterior body 10.

<Effects of the Invention> Since the storage structure of the present invention kills pests and aerobic microorganisms by maintaining the storage space in an oxygen-deficient state as described above, conventional insect prevention methods using insect drying, insect repellent, etc. It has the effect that it is much less labor-intensive and has a reliable pest extermination effect compared to the oxygen-deficient bag Pt20.
Since it is possible to control electrically, there is also the effect that automatic control throughout the four seasons is possible by selecting the control means.
