【発明の詳細な説明】 〔産業上の利用分野〕 本発明は野菜等の保存庫に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a storage for vegetables, etc.

に、野菜等の被保存物の周囲の空気の更新が起ることと
なる。In the conventional storage for vegetables, etc. (hereinafter abbreviated as storage), as shown in Fig. 5, when drawer 1 is pulled out,
Since the gap 8 on the back side was open, external air flows into the space 3 on the back side through the gap 8 due to the negative pressure inside the space 3 on the back side that occurs when the drawer is pulled out. This flow causes the air in the interior space 4 of the drawer 1 to be exchanged with the outside air. In addition, when the storage box body l is pushed into the outer box 2, the positive pressure in the space 3 on the back side causes the internal space 4 to
The air inside is pushed out and replaced with the air in the space 3 on the back. That is, each time the storage is opened and closed during use, the air around the objects to be preserved, such as vegetables, is renewed.
この結果、密閉された保存庫内で野菜等の自らの呼吸作

庫内は冷却されるものであり、この低温の空気も同時に
庫外の高温空気と入れ替ることとなる。これらのことに
より、従来の保存庫の場合、保存期間が短いという欠点
があった。As a result, air with a gas composition favorable for preservation, such as low oxygen concentration and high carbon dioxide concentration, which appears due to the respiration of vegetables etc. in the sealed storage room, mixes with the outside air every time the storage room is opened and closed. It will be replaced. Also, the inside of the storage is usually cooled, and this low-temperature air is also replaced with high-temperature air outside the storage. Due to these factors, conventional storage facilities have the drawback of short storage periods.
本発明は、上記欠点に鑑みて、保存期間の長い野菜等の
保存庫を提供しようとするものである。In view of the above-mentioned drawbacks, the present invention aims to provide a storage for vegetables and the like that has a long shelf life.
本発明の要旨とするところは、引出しを外箱内に摺動自

等の保存庫である。The gist of the present invention is that a drawer is slidably housed in an outer box, a closed space is formed at the back of the drawer whose internal volume increases as the drawer is pulled out, and the closed space and the bottom of the drawer are It is a storage for vegetables, etc., characterized by being formed by communicating with the
本発明の保存庫の一例を第１図に示す。すなわち、引出
し１は外箱２内を、摺動して引出すものであり、引出し

側板１２には通気孔５があけられている。内側板１２と
底板１１の間の空間は背板９の導通部６を経由して密閉
空間３と連通している。An example of a storage according to the present invention is shown in FIG. That is, the drawer 1 is slid into the outer box 2 and pulled out, and the periphery of the back plate 9 of the drawer 1 is kept substantially airtight with the inner surface of the outer box 2. Thus, the back of the back plate 9 of the outer box 2 becomes a sealed space. The bottom part 10 of the drawer 1 is double-layered, and the inner plate 12 thereof is provided with ventilation holes 5. The space between the inner plate 12 and the bottom plate 11 communicates with the closed space 3 via the conductive portion 6 of the back plate 9.
また第２図乃至第４図は他の実施例を示す。すなわち、
密閉空間３を構成するものとして背板９の背部に伸縮自
在の蛇腹状袋７を接続するものである。Further, FIGS. 2 to 4 show other embodiments. That is,
A telescopic bellows-shaped bag 7 is connected to the back of the back plate 9 to constitute the sealed space 3.
この蛇腹状袋７の一端は、引出し１の背板９と密閉接続
され同じ動きをする。またその他の構造は、前述の実施
例とほぼ同一であり、叙上の如くして蛇腹状袋７の内部
と収納箱体１の底部ＩＯの空間が連通ずる構造となって
いる。One end of this bellows-shaped bag 7 is hermetically connected to the back plate 9 of the drawer 1 and moves in the same way. The other structure is almost the same as that of the previous embodiment, and as described above, the inside of the bellows-shaped bag 7 and the space at the bottom IO of the storage box body 1 are in communication with each other.
以下第二の実施例のものについて、収納物の出し入れの
際の引出し１内の空気の移動状況について説明する。Regarding the second embodiment, the movement of air inside the drawer 1 when the stored items are taken out and put in will be explained below.
第３図は被収納物１３が収納され引出しｌが閉じている

。FIG. 3 shows a state in which the object 13 is stored and the drawer l is closed. When the drawer 1 is pulled out from this state by pulling the handle 14, the sealed space 3 at the back of the back plate 9 expands as shown in FIG. The pressure inside the sealed space 3 inside the bag 7 is lower than the outside pressure.For this reason, the outside air flows from the interior space 4 inside the drawer 1 through the ventilation hole 5 and the conductor 6 into the bellows bag 7. Conversely, when the drawer 1 is pushed back, the pressure in the sealed space 3 inside the bellows-shaped bag 7 rises, and the air that has moved into the sealed space 3 is forced into the conductive part 6.
, returns to the drawer 1 through the ventilation hole 5. In this way, the air in the drawer 1 remains the same even after the drawer 1 is opened and closed. In the drawings, white arrows indicate air flow, and hatched arrows indicate the direction of movement of the storage box body 1.
また、第一の実施例においては、空気の移動状況の説明
を省略したが、内部空間４内の空気が密閉空間３との間
で移動する動作は全（同じであり、第二の実施例の如く
蛇腹状袋７を用いていないので移動空気の密閉性に劣る
場合がありうるものである。In addition, in the first embodiment, the explanation of the air movement situation was omitted, but the operation in which the air in the internal space 4 moves between the closed space 3 and the closed space 3 is the same as in the second embodiment. Since the bellows-shaped bag 7 is not used, the airtightness of the moving air may be poor.
−Ｃに野菜等の保存に及ぼす影響の大きい因子としては
、温度と湿度と保存環境のガス組成である。-C factors that have a large influence on the preservation of vegetables and the like are temperature, humidity, and gas composition of the preservation environment.
温度は３〜５°Ｃの低温が良く、湿度は８５〜９５％’
ＲＨＯ高湿度、ガス組成としては、５〜１０％の酸
素濃度、数％の炭酸ガス濃度が良いとされている。A low temperature of 3-5°C is best, and a humidity of 85-95%.
For RHO high humidity and gas composition, it is said that an oxygen concentration of 5 to 10% and a carbon dioxide concentration of several percent are good.
因みに普通の空気の組成のうち酸素濃度は２１％程度、
炭酸ガス濃度は０．０３％であり、保存に適した環境は
、低酸素、高炭酸ガス状態である。これらの状態を保つ
ことが重要であるが、本発明の保存庫によれば被収納物
の出し入れに伴なう開閉動作によっても、引出しｌ内の
空気の状態がほとんど変化せず、良好な状態を保つこと
ができ、保存期間を長くすることが可能である。By the way, the oxygen concentration in the composition of normal air is about 21%.
The carbon dioxide concentration is 0.03%, and the environment suitable for preservation is a low oxygen, high carbon dioxide state. It is important to maintain these conditions, but according to the storage cabinet of the present invention, the air condition inside the drawer 1 hardly changes even when opening and closing operations are performed to take out and take out stored items, and the condition of the air inside the drawer 1 remains in good condition. can be maintained and the storage period can be extended.
なお各状態を保つ手段を記すと以下の通りである。低温

素ガス濃度の三因子は、被収納物である野菜等自身が呼
吸作用により、周囲の酸素を消費し、炭酸ガスと水蒸気
に変えるため、密閉空間であれば、特に機器を用いずと
も達成されるものである。The means for maintaining each state are as follows. Low temperatures can be obtained by cooling with a refrigerator, and the three factors of high humidity, low oxygen concentration, and high carbon gas concentration are caused by the vegetables and other stored items consuming surrounding oxygen through respiration and turning into carbon dioxide. Since it is converted to water vapor, it can be achieved without using any special equipment as long as it is in a closed space.
