保存装置はカーボン材料で面状に形成された導電シート 1 0 と、 この 導電シー ト 1 0にマイナス極またはプラス極が接続された電源 2 0 とか ら構成されている。 導電シー ト 1 0は図 2に示すよ うに四角状に形成さ れている。 導電シー ト 1 0は図 3に示すよ うに 5層構造となっており、 上下方向 （図 3において紙面上下方向） 中央に織物地からなる基材 1 1 と、 この基材 1 1の上下に微粒のカーボンを多量に含有する塗布材が塗 布されてなる導電層 1 2 a， 1 2 b と、 両導電層 1 2 a , 1 2 bの各上 下に形成された防水層 1 3 a， 1 3 b とから構成されている。  The storage device includes a conductive sheet 10 formed of a carbon material in a planar shape, and a power source 20 having a negative electrode or a positive electrode connected to the conductive sheet 10. The conductive sheet 10 is formed in a rectangular shape as shown in FIG. The conductive sheet 10 has a five-layer structure as shown in Fig. 3, and has a base material 11 consisting of a woven fabric in the vertical direction (vertical direction in Fig. 3). A conductive layer 12a, 12b coated with a coating material containing a large amount of fine carbon, and a waterproof layer 13a formed above and below each of both conductive layers 12a, 12b , 13b.
基材 1 1 の上下両端には、 図 2に示すよ うに、 左端から右端まで延在 する複数 （ 5本） の金属製の導線 1 4.a， 1 5 aからそれぞれ構成され る電極 1 4， 1 5が設けられている。 電極 1 4 , 1 5の左端には電源の マイナス極 （またはプラス極） が接続されるターミナル 1 4 b , 1 '5 b が接続されている。 なお導線 1 4 a , 1 5 aは基材 （織物地） 1 1 に織 り込まれている。 これによ り、 電極 1 4および電極 1 5はそれぞれ導電 層 1 2 a , 1 2 bに電気的に接続されている。 The upper and lower ends of the substrate 11 extend from the left end to the right end as shown in Fig. 2. There are provided electrodes 14 and 15 composed of multiple (five) metallic conductors 14.a and 15a, respectively. Terminals 14b and 1'5b to which the negative (or positive) pole of the power supply is connected are connected to the left ends of the electrodes 14 and 15 respectively.

次に、 上述した保存装置による生鮮物の保存について説明する。 図 4 に示すよ うに基台 A上に導電シート 1 0を敷設してこの導電シー ト 1 0 上に肉、 魚、 野菜、 果物などの生鮮物 3 0を載置する。 その後、 電源 2 Next, storage of fresh food by the above-described storage device will be described. As shown in FIG. 4, a conductive sheet 10 is laid on the base A, and a fresh product 30 such as meat, fish, vegetables, and fruits is placed on the conductive sheet 10. Then power 2
0によって電極 1 4のみへマイナス電圧 （一 V Iボルト） の印加を開始 する。 これによ り、 導電シー ト 1 0の電位はマイナス電位 （一 V Iポル ト） となり、 導電シー ト 1 0 と基台 Aあるいは生鮮物 3 0 との間には VA 0 initiates the application of a negative voltage (1 VI volt) to electrodes 14 only. As a result, the potential of the conductive sheet 10 becomes a negative potential (one VI port), and V is applied between the conductive sheet 10 and the base A or fresh food 30.
1の電位差が生じる。 この導電シートに生じたマイナス電位とカーボン 材料からなる導電層 1 2 a， 1 2 bから放射される遠赤外線とによ り、 生鮮物 3 0内に O Hラジカルが発生して生鮮物の還元力が向上され、 高 い還元力を長期間維持するので、 生鮮物 3 0の鮮度を長期間維持するこ とができると推察される。 したがって、 長期間生鮮物の鮮度を維持する ことができる。 A potential difference of 1 occurs. Due to the negative potential generated in the conductive sheet and far-infrared rays emitted from the conductive layers 12a and 12b made of carbon material, OH radicals are generated in the fresh product 30 and the reducing power of the fresh product is reduced. Therefore, it is presumed that the freshness of fresh food 30 can be maintained for a long period of time because the high refining power is maintained for a long time. Therefore, freshness of fresh food can be maintained for a long time.
なお、 上述した実施の形態においては、 電源 2 0の出力端子からマイ ナス電圧を出力しているが、 プラス電圧を出力して導電シー ト 1 0の電 位をプラス電位と してもよい。 また電源 2 0を交流電源と してもよく、 この場合には、 交流電源の出力端子のうちいずれか一つを導電シート 1 0の電極 1 4または電極 1 5に接続すればよい。 これらによっても上述 した作用 ■ 効果を得ることができる。 Although the negative voltage is output from the output terminal of the power supply 20 in the above-described embodiment, a positive voltage may be output to make the potential of the conductive sheet 10 a positive potential.

These also mentioned above Action ■ An effect can be obtained.
