Description

本発明は、収容庫に関する。 The present invention relates to a vault.

従来、下記の特許文献１に記載の収容庫がある。特許文献１に記載の収容庫は、その内部に配置される電極と、電極に電圧を印加する電源とを備えている。収容庫は矩形箱状に形成されている。電極は収容庫の一側壁部の内面に固定されており、電源から印加される電圧に基づいて収容庫の内部に静電界の雰囲気を形成する。これにより、収容庫内に静電界が形成されていない場合と比較すると、収容庫に収容されている生鮮食品等の鮮度を長く保つことが可能となる。 Conventionally, there is a storage described in Patent Document 1 below. The storage described in Patent Document 1 includes an electrode arranged inside the storage and a power source for applying a voltage to the electrode. The vault is formed in the shape of a rectangular box. The electrodes are fixed to the inner surface of one side wall of the storage, and form an atmosphere of an electrostatic field inside the storage based on the voltage applied from the power source. As a result, it is possible to maintain the freshness of the fresh food or the like stored in the storage for a long time as compared with the case where an electrostatic field is not formed in the storage.

特開２００１－２０４４２８号公報Japanese Unexamined Patent Publication No. 2001-204428

特許文献１に記載の収容庫では、収容庫の内部空間に電極が剥き出しの状態で配置されているため、例えば電極の外面に付着する異物を介して電極から収容庫の内壁面に意図しない電流が流れる、いわゆる漏れ電流が発生する可能性がある。電極の外面に付着する異物とは、収容庫の内部空間に存在する水成分や、収容庫の内部に形成される霜、時間の経過に伴って電極の外面に付着する埃等である。漏れ電流が発生すると、電圧印可装置の電流値が上昇するため、消費電力が増加する等の不都合が生じるおそれがある。 In the storage described in Patent Document 1, since the electrodes are arranged in an exposed state in the internal space of the storage, for example, an unintended current from the electrode to the inner wall surface of the storage through a foreign substance adhering to the outer surface of the electrode. There is a possibility that so-called leakage current will occur. The foreign matter adhering to the outer surface of the electrode is a water component existing in the internal space of the storage, frost formed inside the storage, dust adhering to the outer surface of the electrode with the passage of time, and the like. When a leakage current occurs, the current value of the voltage applying device rises, which may cause inconveniences such as an increase in power consumption.

本発明は、こうした実情に鑑みてなされたものであり、その目的は、漏れ電流を抑制しつつ、より均一な電界を形成することが可能な収容庫を提供することにある。 The present invention has been made in view of these circumstances, and an object of the present invention is to provide a storage capable of forming a more uniform electric field while suppressing leakage current.

上記課題を解決する収容庫は、収容室を内部に有する収容庫本体と、収容室に配置される電極部材と、電極部材とは別体からなり、収容庫本体の内面と電極部材との間に配置される中間部材と、を備える。電極部材は、電圧の印加に基づき収容室の内部に電界を形成する電極本体と、電極本体を囲繞する絶縁部材と、を有するとともに、中間部材に固定されている。中間部材は、絶縁材料により形成されている。 The storage that solves the above problems is composed of a storage main body having a storage chamber inside, an electrode member arranged in the storage chamber, and a separate body from the electrode member, and is between the inner surface of the storage main body and the electrode member. It is provided with an intermediate member arranged in. The electrode member has an electrode main body that forms an electric field inside the accommodation chamber based on the application of a voltage, and an insulating member that surrounds the electrode main body, and is fixed to an intermediate member. The intermediate member is made of an insulating material.

この構成のように電極本体の周囲が絶縁部材により囲繞されていれば、電極本体の外面に異物が直接接触し難くなる。そのため、異物を介して電極本体に漏れ電流が発生することを抑制できる。また、収容庫本体の内面と電極部材との間に中間部材が配置されているため、収容庫本体の内面から電極部材を離間させることができる。これにより、電極部材から、収容庫本体の内部に向かうことなく、収容庫本体の内面に直接向かうような電界が形成され難くなる。しかも、中間部材が絶縁材料により形成されているため、この構成によっても、電極部材から収容庫本体の内面に直接向かうような電界が形成され難くなる。よって、より均一な電界を収容庫本体の内部に形成することが可能となる。 If the periphery of the electrode body is surrounded by an insulating member as in this configuration, it becomes difficult for foreign matter to come into direct contact with the outer surface of the electrode body. Therefore, it is possible to suppress the generation of leakage current in the electrode body via foreign matter. Further, since the intermediate member is arranged between the inner surface of the storage body and the electrode member, the electrode member can be separated from the inner surface of the storage body. As a result, it becomes difficult to form an electric field that directly directs from the electrode member to the inner surface of the storage body without going to the inside of the storage body. Moreover, since the intermediate member is formed of an insulating material, it is difficult to form an electric field directly from the electrode member to the inner surface of the storage body even with this configuration. Therefore, a more uniform electric field can be formed inside the housing body.

上記の収容庫において、電極本体及び絶縁部材は一体成形されていることが好ましい。
この構成によれば、絶縁部材により電極本体を補強できるため、電極本体を可能な限り薄型化することができる。そのため、電極部材を軽量化することが可能となる。 In the above storage, it is preferable that the electrode body and the insulating member are integrally molded.
According to this configuration, since the electrode body can be reinforced by the insulating member, the electrode body can be made as thin as possible. Therefore, the weight of the electrode member can be reduced.

上記の収容庫において、絶縁部材は樹脂により形成されていることが好ましい。
この構成によれば、電極本体及び絶縁部材を容易に一体化させることが可能となる。
上記課題を解決する他の収容庫は、収容室を内部に有する収容庫本体と、収容室に配置される電極部材と、電極部材とは別体からなり、収容庫本体の内面と電極部材との間に配置される中間部材と、を備える。電極部材は、電圧の印加に基づき収容室の内部に電界を形成する電極本体と、電極本体を厚さ方向に挟み込む第１絶縁部材及び第２絶縁部材と、を有するとともに、中間部材に固定されている。中間部材は、絶縁材料により形成されている。 In the above storage, the insulating member is preferably made of resin.
According to this configuration, the electrode body and the insulating member can be easily integrated.
The other storage that solves the above problems is composed of a storage main body having a storage chamber inside, an electrode member arranged in the storage chamber, and an electrode member, and the inner surface of the storage main body and the electrode member. It is provided with an intermediate member arranged between the two. The electrode member has an electrode body that forms an electric field inside the accommodation chamber based on the application of a voltage, and a first insulating member and a second insulating member that sandwich the electrode body in the thickness direction, and is fixed to the intermediate member. ing. The intermediate member is made of an insulating material.

この構成のように第１絶縁部材及び第２絶縁部材により電極本体が挟み込まれていれば、電極本体の外面の殆どを第１絶縁部材及び第２絶縁部材により覆うことができる。よって、電極本体の外面に異物が直接接触し難くなるため、異物を介して電極本体に漏れ電流が発生することを抑制できる。また、収容庫本体の内面と電極部材との間に中間部材が配置されているため、収容庫本体の内面から電極部材を離間させることができる。これにより、電極部材から、収容庫本体の内部に向かうことなく、収容庫本体の内面に直接向かうような電界が形成され難くなる。しかも、中間部材が絶縁材料により形成されているため、この構成によっても、電極部材から収容庫本体の内面に直接向かうような電界が形成され難くなる。よって、より均一な電界を収容庫本体の内部に形成することが可能となる。 If the electrode body is sandwiched between the first insulating member and the second insulating member as in this configuration, most of the outer surface of the electrode body can be covered by the first insulating member and the second insulating member. Therefore, it is difficult for foreign matter to come into direct contact with the outer surface of the electrode body, and it is possible to suppress the generation of leakage current in the electrode body via the foreign matter. Further, since the intermediate member is arranged between the inner surface of the storage body and the electrode member, the electrode member can be separated from the inner surface of the storage body. As a result, it becomes difficult to form an electric field that directly directs from the electrode member to the inner surface of the storage body without going to the inside of the storage body. Moreover, since the intermediate member is formed of an insulating material, it is difficult to form an electric field directly from the electrode member to the inner surface of the storage body even with this configuration. Therefore, a more uniform electric field can be formed inside the housing body.

上記の収容庫において、中間部材は、矩形状に形成されており、電極部材は、中間部材の底面に固定されていることが好ましい。
上記の収容庫において、中間部材は、平坦な底部と、底部から連続して形成される一対の脚部とを有する断面ハット状に形成されており、電極部材は、中間部の底部に固定されていることが好ましい。 In the above storage, the intermediate member is preferably formed in a rectangular shape, and the electrode member is preferably fixed to the bottom surface of the intermediate member.
In the above storage, the intermediate member is formed in a cross-sectional hat shape having a flat bottom portion and a pair of leg portions continuously formed from the bottom portion, and the electrode member is fixed to the bottom portion of the intermediate portion. Is preferable.

上記の収容庫において、電極に電圧を印加する変圧器と、変圧器を制御する制御盤と、を備え、変圧器の総重量は３６［ｋｇ］未満であることが好ましい。
上記の収容庫は、新品又は中古品であることが好ましい。 In the above-mentioned storage, a transformer for applying a voltage to the electrodes and a control panel for controlling the transformer are provided, and the total weight of the transformer is preferably less than 36 [kg].

In order to improve the refrigerating performance of the storage 10, a heat insulating material for suppressing heat transfer from the storage chamber S10 to the outside of the storage 10 is embedded in each of the box body 40 and the door portion 50. ..

図１に示されるように、一対の扉部５０は、箱体４０に対して開閉自在に連結されている。収容庫１０では、扉部５０を開くことにより収容室Ｓ１０に任意の物品を入れたり、収容室Ｓ１０に収容されている物品を外部に持ち出したりすることが可能となる。また、扉部５０を閉じることにより収容室Ｓ１０が閉空間となり、収容室Ｓ１０の内部の物品が冷却環境下で保存される。 As shown in FIG. 1, the pair of door portions 50 are openably and closably connected to the box body 40. In the storage room 10, by opening the door portion 50, it is possible to put an arbitrary article in the storage room S10 or take out the article stored in the storage room S10 to the outside. Further, by closing the door portion 50, the accommodation chamber S10 becomes a closed space, and the articles inside the accommodation chamber S10 are stored in a cooling environment.

冷却装置３０は、電力の供給に基づいて駆動することにより収容室Ｓ１０に冷風を供給して、収容室Ｓ１０内を冷却する。
図２に示されるように、収容庫１０は、収容庫本体２０の上壁部４１の内面付近に配置される中間部材６０及び電極部材７０を更に備えている。 The cooling device 30 supplies cold air to the accommodation chamber S10 by driving based on the supply of electric power, and cools the inside of the accommodation chamber S10.
As shown in FIG. 2, the storage 10 further includes an intermediate member 60 and an electrode member 70 arranged near the inner surface of the upper wall portion 41 of the storage main body 20.

中間部材６０は、樹脂等の絶縁材料により矩形状に形成されている。中間部材６０は電極部材７０とは別体である。収容庫本体２０の右側壁部４２の上部及び左側壁部４３の上部には載置部材８０，８１が固定してそれぞれ設けられている。載置部材８０，８１は、樹脂等の絶縁材料により略Ｌ字状に形成されている。なお、載置部材８０，８１は、絶縁性を有していない材料、例えば金属により形成されていてもよい。載置部材８０，８１に中間部材６０の両端部がそれぞれ載せられることにより、収容室Ｓ１０の上方に中間部材６０が設置されている。中間部材６０の底面には、電極部材７０が固定して設けられている。中間部材６０は、収容庫本体２０の上壁部４１の内面と電極部材７０との間に配置されている。 The intermediate member 60 is formed in a rectangular shape by an insulating material such as resin. The intermediate member 60 is separate from the electrode member 70. The mounting members 80 and 81 are fixedly provided on the upper part of the right side wall portion 42 and the upper part of the left side wall portion 43 of the storage body 20, respectively. The mounting members 80 and 81 are formed in a substantially L shape by an insulating material such as resin. The mounting members 80 and 81 may be made of a material having no insulating property, for example, metal. By mounting both ends of the intermediate member 60 on the mounting members 80 and 81, the intermediate member 60 is installed above the accommodation chamber S10. An electrode member 70 is fixedly provided on the bottom surface of the intermediate member 60. The intermediate member 60 is arranged between the inner surface of the upper wall portion 41 of the storage body 20 and the electrode member 70.

図３及び図４に示されるように、電極部材７０は矩形板状に形成されている。なお、図３及び図４等では、電極部材７０の長手方向が矢印Ｘで示され、その短手方向が矢印Ｙで示されている。電極部材７０は、電極本体７１と、絶縁部材７２と、配線７５とを有している。
電極本体７１は、鋼材等の金属材料により薄板状に形成されている。電極本体７１は絶縁部材７２により囲繞されている。電極本体７１の外面は、配線７５が接続されている部分を除き、全面に亘って絶縁部材７２により覆われている。 As shown in FIGS. 3 and 4, the electrode member 70 is formed in a rectangular plate shape. In FIGS. 3 and 4, the longitudinal direction of the electrode member 70 is indicated by an arrow X, and the lateral direction thereof is indicated by an arrow Y. The electrode member 70 has an electrode body 71, an insulating member 72, and wiring 75.
The electrode body 71 is formed in a thin plate shape by a metal material such as a steel material. The electrode body 71 is surrounded by an insulating member 72. The outer surface of the electrode body 71 is covered with the insulating member 72 over the entire surface except the portion to which the wiring 75 is connected.

絶縁部材７２は、樹脂等の絶縁材料により板状に形成されている。図３に示されるように、絶縁部材７２には、その厚さ方向に貫通する挿入孔７２０が外縁部及び中央部に沿って複数形成されている。電極部材７０は、挿入孔７２０に挿入されるねじ等により、図２に示される中間部材６０に固定して組み付けられている。 The insulating member 72 is formed in a plate shape by an insulating material such as resin. As shown in FIG. 3, a plurality of insertion holes 720 penetrating in the thickness direction of the insulating member 72 are formed along the outer edge portion and the central portion. The electrode member 70 is fixedly assembled to the intermediate member 60 shown in FIG. 2 by a screw or the like inserted into the insertion hole 720.

図３及び図４に示されるように、配線７５は、電極本体７１の一端部から絶縁部材７２を貫通して外部に露出するように形成されている。配線７５は、電極本体７１に電圧を印加するためのものである。
電極部材７０の製造の際に電極本体７１及び絶縁部材７２は一体成形される。例えば、電極部材７０に対応したキャビティを有する金型を用いる場合には、配線７５が接続された電極本体７１を金型の内部に配置した後、その金型の内部に溶融樹脂を流し込む。続いて、金型を冷却した後、その金型を樹脂成形品から取り外せば、樹脂からなる絶縁部材７２が電極本体７１を囲繞するように一体成形された電極部材７０を製造することができる。 As shown in FIGS. 3 and 4, the wiring 75 is formed so as to penetrate the insulating member 72 from one end of the electrode main body 71 and be exposed to the outside. The wiring 75 is for applying a voltage to the electrode main body 71.
When the electrode member 70 is manufactured, the electrode body 71 and the insulating member 72 are integrally molded. For example, when a mold having a cavity corresponding to the electrode member 70 is used, the electrode main body 71 to which the wiring 75 is connected is arranged inside the mold, and then the molten resin is poured into the mold. Subsequently, after cooling the mold, if the mold is removed from the resin molded product, the electrode member 70 in which the insulating member 72 made of resin is integrally molded so as to surround the electrode main body 71 can be manufactured.

図３に示されるように、配線７５は、収容庫本体２０の内部又は外部に設けられる電圧印加装置９０に接続されている。電圧印加装置９０は、変圧器９１及び制御盤９２等を有して構成されており、所定の高電圧を電極本体７１に配線７５を介して印加する。変圧器９１は、電源から供給される電圧を昇圧して電極本体７１に印加する。制御盤９２は、変圧器９１を制御するための各種回路等を有している。電圧印加装置９０から電極本体７１に印加される高電圧は、例えば時間の経過に伴って周期的に大きさや向きが変化する交番電圧であってもよいし、時間の経過に伴って大きさや向きが変化しない一定の電圧であってもよい。電極本体７１は、電圧印加装置９０により印加される高電圧に基づいて収容室Ｓ１０内に電界を形成する。 As shown in FIG. 3, the wiring 75 is connected to a voltage application device 90 provided inside or outside the storage body 20. The voltage applying device 90 includes a transformer 91, a control panel 92, and the like, and applies a predetermined high voltage to the electrode main body 71 via wiring 75. The transformer 91 boosts the voltage supplied from the power source and applies it to the electrode body 71. The control panel 92 has various circuits and the like for controlling the transformer 91. The high voltage applied from the voltage applying device 90 to the electrode main body 71 may be, for example, an alternating voltage whose magnitude and direction change periodically with the passage of time, or the magnitude and direction with the passage of time. May be a constant voltage that does not change. The electrode body 71 forms an electric field in the accommodation chamber S10 based on the high voltage applied by the voltage applying device 90.

次に、本実施形態の収容庫１０の作用及び効果について説明する。なお、以下では、収容室Ｓ１０に収容されている物品を収容物とも称する。
収容室Ｓ１０内に電界が形成されることにより、収容室Ｓ１０内の収容物に殺菌処理を施すことができるとともに、収容物の熟成を促進させることもできる。そのため、鮮度を保ったまま収容物を長期間に亘って保存することができるとともに、収容物の旨味を増幅させることができる。また、所定の電界の環境下に収容物が存在することにより収容物の凍結点を下げることができるため、より低温の環境下、例えばマイナス温度の環境下であっても凍結することなく収容物を保存することができる。そのため、収容物の鮮度をより長期間に亘って維持することが可能となる。 Next, the operation and effect of the storage 10 of the present embodiment will be described. In the following, the articles stored in the storage chamber S10 will also be referred to as contained items.
By forming an electric field in the storage chamber S10, the contents in the storage chamber S10 can be sterilized and the aging of the contents can be promoted. Therefore, the contained material can be stored for a long period of time while maintaining its freshness, and the umami of the contained material can be amplified. Further, since the freezing point of the contained material can be lowered by the presence of the contained material in the environment of a predetermined electric field, the contained material does not freeze even in a lower temperature environment, for example, an environment of a negative temperature. Can be saved. Therefore, it is possible to maintain the freshness of the contained material for a longer period of time.

また、本実施形態の収容庫１０では、電極本体７１が絶縁部材７２により囲繞されているため、電極本体７１の外面に異物が直接接触し難くなる。よって、異物を介して電極本体７１に漏れ電流が発生することを抑制できる。
図５（Ａ）は、比較例の電極部材を用いたときの漏れ電流と、本実施形態の電極部材７０を用いたときの漏れ電流とを実験的に測定することにより得られた図表である。比較例の電極部材は、電極本体が露出している構造、換言すれば電極本体が絶縁部材により囲繞されていない構造を有している。比較例の電極部材の表面積は「１６．３２［ｍ2］」に設定されている。これに対し、本実施形態の電極部材７０の表面積は「１４．４８［ｍ2］」に設定されている。この実験では、比較例の電極部材を用いた場合に「１８［ｍＡ］」の漏れ電流が測定され、実施形態の電極部材７０を用いた場合に「８［ｍＡ］」の漏れ電流が測定された。したがって、比較例の電極部材と比較すると、本実施形態の電極部材７０では約４１［％］の漏れ電流を削減することが可能である。ちなみに、単位表面積当たりの電流値に関しても、比較例の電極部材よりも、本実施形態の電極部材７０の方が小さくなる。 Further, in the storage 10 of the present embodiment, since the electrode main body 71 is surrounded by the insulating member 72, it is difficult for foreign matter to come into direct contact with the outer surface of the electrode main body 71. Therefore, it is possible to suppress the generation of leakage current in the electrode body 71 via foreign matter.
FIG. 5A is a chart obtained by experimentally measuring the leakage current when the electrode member of the comparative example is used and the leakage current when the electrode member 70 of the present embodiment is used. .. The electrode member of the comparative example has a structure in which the electrode body is exposed, in other words, a structure in which the electrode body is not surrounded by an insulating member. The surface area of the electrode member of the comparative example is set to "16.32 [m 2 ]". On the other hand, the surface area of the electrode member 70 of the present embodiment is set to "14.48 [m 2 ]". In this experiment, the leakage current of "18 [mA]" was measured when the electrode member of the comparative example was used, and the leakage current of "8 [mA]" was measured when the electrode member 70 of the embodiment was used. rice field. Therefore, as compared with the electrode member of the comparative example, the electrode member 70 of the present embodiment can reduce the leakage current by about 41 [%]. Incidentally, regarding the current value per unit surface area, the electrode member 70 of the present embodiment is smaller than the electrode member of the comparative example.

図５（Ｂ）は、比較例の電極部材及び本実施形態の電極部材７０のそれぞれの表面積を同一の値に設定したときの漏れ電流を実験的に測定することにより得られた図表である。なお、比較例の電極部材及び比較例の電極部材７０のそれぞれの表面積は共に「５００［ｍｍ］×４００［ｍｍ］に設定した。この実験では、比較例の電極部材を用いた場合に［０．１５［ｍＡ］］の漏れ電流が検出され、本実施形態の電極部材７０を用いた場合に「０．０９［ｍＡ］」の漏れ電流が検出された。この実験でも、比較例の電極部材と比較すると、本実施形態の電極部材７０では約４０［％］の漏れ電流を削減可能であることが確認された。このように漏れ電流が削減されることにより、電極部材７０に供給すべき電流値を低減することができるため、結果として、より小さい変圧器９１を用いることができる。よって、収容庫１０の全体の重量を従来の収容庫よりも軽くすることが可能である。 FIG. 5B is a chart obtained by experimentally measuring the leakage current when the surface areas of the electrode member of the comparative example and the electrode member 70 of the present embodiment are set to the same value. The surface areas of the electrode member of the comparative example and the electrode member 70 of the comparative example were both set to "500 [mm] × 400 [mm]. In this experiment, when the electrode member of the comparative example was used, [0]. A leakage current of .15 [mA]] was detected, and a leakage current of “0.09 [mA]” was detected when the electrode member 70 of the present embodiment was used. Also in this experiment, it was confirmed that the electrode member 70 of the present embodiment can reduce the leakage current by about 40 [%] as compared with the electrode member of the comparative example. By reducing the leakage current in this way, the current value to be supplied to the electrode member 70 can be reduced, and as a result, a smaller transformer 91 can be used. Therefore, the total weight of the storage 10 can be made lighter than that of the conventional storage.

また、図２に示されるように、収容庫本体２０の上壁部４１の内面と電極部材７０との間に中間部材６０が配置されているため、収容庫本体２０の上壁部４１の内面から電極部材７０を離間させることができる。これにより、電極部材７０から、収容庫本体２０の内部に向かうことなく、収容庫本体２０の上壁部４１の内面に直接向かうような電界が形成され難くなる。しかも、中間部材６０が絶縁材料により形成されているため、この構成によっても、電極部材７０から収容庫本体２０の上壁部４１の内面に直接向かうような電界が形成され難くなる。よって、より均一な電界を収容庫本体２０の内部に形成することが可能となる。さらに、本実施形態のように収容庫本体２０の上壁部４１の内面と電極部材７０との間に中間部材６０が配置されている構成であれば、収容庫本体２０の上壁部４１の内面と電極部材７０との間に単にスペースが形成されている構成と比較すると、構造的な強度を高めることが可能である。 Further, as shown in FIG. 2, since the intermediate member 60 is arranged between the inner surface of the upper wall portion 41 of the storage main body 20 and the electrode member 70, the inner surface of the upper wall portion 41 of the storage main body 20 is arranged. The electrode member 70 can be separated from the electrode member 70. As a result, it becomes difficult to form an electric field from the electrode member 70 so as to directly go to the inner surface of the upper wall portion 41 of the storage body 20 without going to the inside of the storage body 20. Moreover, since the intermediate member 60 is formed of an insulating material, it is difficult to form an electric field directly from the electrode member 70 toward the inner surface of the upper wall portion 41 of the storage body 20 even with this configuration. Therefore, a more uniform electric field can be formed inside the storage body 20. Further, if the intermediate member 60 is arranged between the inner surface of the upper wall portion 41 of the storage main body 20 and the electrode member 70 as in the present embodiment, the upper wall portion 41 of the storage main body 20 It is possible to increase the structural strength as compared with the configuration in which a space is simply formed between the inner surface and the electrode member 70.

一方、本実施形態の収容庫１０では、電極本体７１及び絶縁部材７２が一体成形されている。この構成によれば、絶縁部材７２により電極本体７１を補強できるため、電極本体７１を可能な限り薄型化することができる。そのため、電極部材７０を軽量化することが可能となる。 On the other hand, in the storage 10 of the present embodiment, the electrode body 71 and the insulating member 72 are integrally molded. According to this configuration, since the electrode main body 71 can be reinforced by the insulating member 72, the electrode main body 71 can be made as thin as possible. Therefore, the weight of the electrode member 70 can be reduced.

図６は、比較例の収容庫の電極部材の重量及び本実施形態の収容庫１０の電極部材７０の重量を実験的に計測することにより得られた図表である。比較例の収容庫は、電極本体が絶縁部材により囲繞されていない構造を有しているため、その電極本体に所要の剛性が必要となる。そのため、電極本体の重量が大きくなり易い。この点、本実施形態の収容庫１０では、絶縁部材７２により電極本体７１を補強できるため、図６に示されるように、比較例の収容庫と比較すると、本実施形態の収容庫１０では電極部材の重量を「４００［ｋｇ］」程度軽量化することが可能である。電極部材の軽量化により、本実施形態の収容庫１０では、比較例の収容庫に対して載積重量を増加させることができる。 FIG. 6 is a chart obtained by experimentally measuring the weight of the electrode member of the storage of the comparative example and the weight of the electrode member 70 of the storage 10 of the present embodiment. Since the housing of the comparative example has a structure in which the electrode body is not surrounded by the insulating member, the electrode body needs to have the required rigidity. Therefore, the weight of the electrode body tends to increase. In this respect, in the storage 10 of the present embodiment, the electrode main body 71 can be reinforced by the insulating member 72. Therefore, as shown in FIG. 6, as compared with the storage of the comparative example, the storage 10 of the present embodiment has an electrode. It is possible to reduce the weight of the member by about "400 [kg]". By reducing the weight of the electrode members, in the storage 10 of the present embodiment, the loading weight can be increased as compared with the storage of the comparative example.

また、上述の通り、本実施形態の電極部材７０では漏れ電流を削減することができるため、電圧印加装置９０を軽量化することもできる。具体的には、図６に示されるように、比較例の収容庫と比較すると、本実施形態の収容庫１０では電圧印加装置の重量を「８０［ｋｇ］」程度軽量化することが可能である。結果として、収容庫全体として見たときに、比較例の収容庫と比較すると、本実施形態の収容庫１０では「４８０［ｋｇ］」程度軽量化が可能である。 Further, as described above, since the leakage current can be reduced in the electrode member 70 of the present embodiment, the weight of the voltage applying device 90 can be reduced. Specifically, as shown in FIG. 6, the weight of the voltage applying device can be reduced by about "80 [kg]" in the storage 10 of the present embodiment as compared with the storage of the comparative example. be. As a result, when viewed as a whole, the weight of the storage 10 of the present embodiment can be reduced by about "480 [kg]" as compared with the storage of the comparative example.

一方、従来の収容庫では、生鮮食品の鮮度の確保等に関してより高い効果を得るためには、より強度の高い電界を形成する必要がある。すなわち、より高い電圧を電極に印加する必要がある。このような要求に対応するために、電圧印加装置から電極に印加される電圧のパターンには、低電圧に対応した電圧パターンだけでなく、高電圧に対応した電圧パターン等の複数のパターンが設けられている。複数の電圧パターンを実現するためには、それらに対応した変圧器の容量が必要となる。結果的に従来の収容庫では複数の変圧器を搭載しなければならなくなっている。これが電圧印加装置の重量を増加させ、ひいては収容庫全体の重量を増加させる要因になっている。 On the other hand, in the conventional storage, it is necessary to form a stronger electric field in order to obtain a higher effect on ensuring the freshness of fresh food. That is, it is necessary to apply a higher voltage to the electrodes. In order to meet such demands, the voltage pattern applied to the electrodes from the voltage application device includes not only a voltage pattern corresponding to a low voltage but also a plurality of patterns such as a voltage pattern corresponding to a high voltage. Has been done. In order to realize multiple voltage patterns, the capacity of the transformer corresponding to them is required. As a result, conventional vaults have to be equipped with multiple transformers. This is a factor that increases the weight of the voltage applying device and, by extension, the weight of the entire storage.

これに対して、本実施形態の収容庫１０では、上述の通り、より均一な電界を収容庫１０内に形成することが可能であるため、電圧パターンの数を減らしたとしても、十分な電界強度を得られる可能性が高い。電圧パターンの数を減らすことができれば、変圧器の容量を減少させることができる。すなわち、変圧器９１の数を減らすことができる。したがって、本実施形態の収容庫１０では変圧器９１の総重量及び総体積を従来の収容庫よりも減らすことが可能である。 On the other hand, in the storage 10 of the present embodiment, as described above, a more uniform electric field can be formed in the storage 10, so that even if the number of voltage patterns is reduced, a sufficient electric field is sufficient. There is a high possibility that strength can be obtained. If the number of voltage patterns can be reduced, the capacity of the transformer can be reduced. That is, the number of transformers 91 can be reduced. Therefore, in the storage 10 of the present embodiment, the total weight and the total volume of the transformer 91 can be reduced as compared with the conventional storage.

具体的には、従来の収容庫では、電圧印加装置から電極に印加される電圧パターンとして、例えば２［ｋＶ］から７［ｋＶ］の範囲で１［ｋＶ］毎に設定される電圧パターンが用いられており、合計６つの電圧パターンが用いられている。この６つの電圧パターンを実現するためには、電圧印加装置に６つの変圧器が必要となる。したがって、１つの変圧器当たりの重量が「６［ｋｇ］」であるとすると、変圧器の総重量が「３６［ｋｇ］（＝６［ｋｇ］×６）」となる。これに対して、本実施形態の収容庫１０では、変圧器９１の数を６つよりも減らすことができるため、変圧器の総重量を「３６［ｋｇ］」未満にすることが可能である。 Specifically, in the conventional storage, as the voltage pattern applied to the electrodes from the voltage application device, for example, a voltage pattern set every 1 [kV] in the range of 2 [kV] to 7 [kV] is used. A total of 6 voltage patterns are used. In order to realize these six voltage patterns, six transformers are required for the voltage application device. Therefore, assuming that the weight per transformer is "6 [kg]", the total weight of the transformer is "36 [kg] (= 6 [kg] x 6)". On the other hand, in the storage 10 of the present embodiment, the number of transformers 91 can be reduced to less than 6, so that the total weight of the transformers can be reduced to less than "36 [kg]". ..

同様に、一つの変圧器当たりの体積が「０．００５９４［ｍ3］」であるとすると、従来の収容庫では、変圧器の総体積が「０．０３５６４［ｍ3］（＝０．００５９４［ｍ3］×６）」となる。これに対して、本実施形態の収容庫１０では、変圧器９１の数を６つよりも減らすことができるため、変圧器９１の総体積を「０．０３５６４［ｍ3］」未満にすることが可能である。 Similarly, assuming that the volume per transformer is "0.00594 [m 3 ]", in the conventional storage, the total volume of the transformer is "0.03564 [m 3 ] (= 0.00594]". [M 3 ] x 6) ”. On the other hand, in the storage 10 of the present embodiment, the number of transformers 91 can be reduced to less than 6, so that the total volume of the transformers 91 should be less than "0.03564 [m 3 ]". Is possible.

また、本実施形態の収容庫１０では、電極部材７０の絶縁部材７２が樹脂により形成されている。この構成によれば、上述した製造方法を用いることにより電極本体７１及び絶縁部材７２を容易に一体化させることができる。
（変形例）
次に、第１実施形態の収容庫１０の変形例について説明する。 Further, in the storage 10 of the present embodiment, the insulating member 72 of the electrode member 70 is formed of resin. According to this configuration, the electrode body 71 and the insulating member 72 can be easily integrated by using the above-mentioned manufacturing method.
(Modification example)
Next, a modification of the storage 10 of the first embodiment will be described.

図７に示されるように、本変形例の電極部材７０は、電極本体７１と、第１絶縁部材７３と、第２絶縁部材７４とを有している。第１絶縁部材７３及び第２絶縁部材７４は、樹脂等の絶縁材料により平板状に形成されている。電極本体７１は第１絶縁部材７３及び第２絶縁部材７４により挟み込まれている。電極本体７１の板厚方向の一方の外面７１０は全面に亘って第１絶縁部材７３により覆われている。電極本体７１の板厚方向の他方の外面７１１は全面に亘って第２絶縁部材７４により覆われている。各絶縁部材７３，７４は電極本体７１に接着等により固定されている。 As shown in FIG. 7, the electrode member 70 of this modification has an electrode main body 71, a first insulating member 73, and a second insulating member 74. The first insulating member 73 and the second insulating member 74 are formed in a flat plate shape by an insulating material such as resin. The electrode body 71 is sandwiched between the first insulating member 73 and the second insulating member 74. One outer surface 710 in the plate thickness direction of the electrode body 71 is covered with a first insulating member 73 over the entire surface. The other outer surface 711 of the electrode body 71 in the plate thickness direction is covered with the second insulating member 74 over the entire surface. The insulating members 73 and 74 are fixed to the electrode body 71 by adhesion or the like.

この構成のように第１絶縁部材７３及び第２絶縁部材７４により電極本体７１が厚さ方向に挟み込まれていれば、電極本体７１の外面の殆どを第１絶縁部材７３及び第２絶縁部材７４により覆うことができる。よって、電極本体７１の外面に異物が直接接触し難くなるため、異物を介して電極本体７１に漏れ電流が発生することを抑制できる。 If the electrode body 71 is sandwiched between the first insulating member 73 and the second insulating member 74 in the thickness direction as in this configuration, most of the outer surface of the electrode body 71 is covered with the first insulating member 73 and the second insulating member 74. Can be covered with. Therefore, it is difficult for foreign matter to come into direct contact with the outer surface of the electrode body 71, and it is possible to suppress the generation of leakage current in the electrode body 71 via the foreign matter.

＜第２実施形態＞
次に、第２実施形態の収容庫１０について説明する。以下、第１実施形態の収容庫１０との相違点を中心に説明する。
本実施形態の収容庫１０では、図８に示される複数の中間部材６０が用いられている。図８に示されるように、中間部材６０はＹ方向に延びるように形成されている。中間部材６０は、Ｙ方向に直交する断面がハット状に形成される形状を有しており、平坦な底部６１と、底部６１から連続して形成される一対の脚部６２，６３とを有している。 <Second Embodiment>
Next, the storage 10 of the second embodiment will be described. Hereinafter, the differences from the storage 10 of the first embodiment will be mainly described.
In the storage 10 of the present embodiment, a plurality of intermediate members 60 shown in FIG. 8 are used. As shown in FIG. 8, the intermediate member 60 is formed so as to extend in the Y direction. The intermediate member 60 has a shape in which a cross section orthogonal to the Y direction is formed in a hat shape, and has a flat bottom portion 61 and a pair of leg portions 62, 63 continuously formed from the bottom portion 61. is doing.

図９に示されるように、各中間部材６０の底部６１には複数の貫通孔６１０が形成されている。中間部材６０に形成される複数の貫通孔６１０のそれぞれの位置は、図３に示される電極部材７０においてＹ方向に並ぶ複数の挿入孔７２０のそれぞれの位置と一致している。互いに位置が一致する中間部材６０の貫通孔６１０及び電極部材７０の挿入孔７２０にねじ等がねじ込まれることにより、一つの電極部材７０に複数の中間部材６０が締結されて固定されている。 As shown in FIG. 9, a plurality of through holes 610 are formed in the bottom portion 61 of each intermediate member 60.
