　本発明は、家庭用冷蔵庫、業務用冷蔵庫、プレハブ、大型冷蔵室、コンテナ、及びトラックの内部空間を過冷却が生じる状態に調整することが可能な電場形成パネル、及びこの電場形成パネルが設けられた家庭用冷蔵庫、業務用冷蔵庫、プレハブ、大型冷蔵室、コンテナ、及びトラックに関するものである。 The present invention provides an electric field forming panel capable of adjusting the internal space of a household refrigerator, a commercial refrigerator, a prefabricated, a large refrigerator compartment, a container, and a truck to a state where supercooling occurs, and the electric field forming panel Household refrigerators, commercial refrigerators, prefabs, large refrigerator compartments, containers, and trucks.
　従来から、静電場に基づく水分子の振動を利用して過冷却現象を引き起こし、氷結点以下の環境で食品に含まれる水分等を非凍結状態に保持し、食品等の鮮度劣化、腐敗防止等を図る冷蔵庫や静電場処理装置が提案されている（例えば、特許文献１から４）。
　これらの文献には、冷蔵庫等に独立した区画を設け、この区画に過冷却現象を引き起こすための電場形成手段を内蔵させた構成や、冷蔵庫等を改造することによって電場形成手段を設けた構成等により、過冷却を起こす冷蔵庫等に係る技術が開示されている。 Conventionally, the supercooling phenomenon is caused by utilizing vibration of water molecules based on electrostatic field, and the water contained in food is kept in a non-freezing state in the environment below freezing point, freshness deterioration of food etc. prevention of rot etc There have been proposed refrigerators and electrostatic field treatment apparatuses for achieving the above (for example, Patent Documents 1 to 4).
In these documents, an independent section is provided in a refrigerator or the like, and an electric field forming unit for causing a supercooling phenomenon is built in this section, or a configuration in which the electric field forming unit is provided by modifying the refrigerator or the like Discloses a technique relating to a refrigerator or the like that causes subcooling.

　しかし、上記特許文献１から４に提案されているように、家庭用冷蔵庫や業務用冷蔵庫等に過冷却現象を引き起こすために、一旦、電場形成手段を内蔵させたり、改造して設けたりすれば、通常の家庭用冷蔵庫や業務用冷蔵庫等に戻すことは構造的に困難が伴う。そして、家庭用冷蔵庫等の内部を改造することは、手間とコストがかかるという問題がある。 However, as proposed in Patent Documents 1 to 4 above, in order to cause a supercooling phenomenon in a household refrigerator, a commercial refrigerator, etc., once the electric field forming means is built in or modified and provided. However, it is structurally difficult to return to a normal household refrigerator or a commercial refrigerator. And, there is a problem that it takes time and cost to remodel the inside of a household refrigerator or the like.
　また、家庭用冷蔵庫等の貯蔵室に電場空間を形成すると、結露を通じた漏電、過電圧の印加による放電を回避するため、十分な絶縁対策を施す必要がある。しかし、このような絶縁対策のために所望の収容容積を得ることが、冷蔵庫等を大型化しなければ解決されない問題がある。絶縁対策として、例えば、貯蔵室の上下面に接して絶縁用碍子をそれぞれ配置することが考えられる。しかし、貯蔵室の上下面に接して絶縁用碍子をそれぞれ配置すると、貯蔵室の収容容積が元の７割から８割に減ってしまう。
　さらに、上記特許文献１から４に提案されている発明では、電極に身体（例えば、手や腕）が接触した際に電撃が生じるおそれがある。これを避けるための手段を別に講じる必要がある。 In addition, when an electric field space is formed in a storage room such as a home refrigerator, it is necessary to take sufficient insulation measures in order to avoid electric leakage due to condensation and discharge due to application of overvoltage. However, there is a problem that obtaining a desired storage capacity for such insulation measures can not be solved unless the size of the refrigerator or the like is increased. As insulation measures, for example, it is conceivable to dispose insulating insulators in contact with the upper and lower surfaces of the storage chamber. However, when insulating insulators are disposed in contact with the upper and lower surfaces of the storage chamber, the storage capacity of the storage chamber is reduced from 70% to 80% of the original.
Furthermore, in the inventions proposed in Patent Documents 1 to 4 described above, there is a possibility that an electric shock may occur when a body (for example, a hand or an arm) contacts the electrode. It is necessary to take other measures to avoid this.
　そこで、本発明は、家庭用冷蔵庫、業務用冷蔵庫、プレハブ、大型冷蔵室、コンテナ、トラックの貯蔵室の環境を過冷却が生じるように整えることが可能であって、貯蔵室に容易に設置することができる電場形成パネル及びこの電場形成パネルが取り付けられた家庭用冷蔵庫、業務用冷蔵庫、プレハブ、大型冷蔵室、コンテナ、トラックを提供することを目的とする。 Therefore, according to the present invention, it is possible to arrange the environment of the storage compartments of a household refrigerator, a commercial refrigerator, a prefabricated, a large refrigerator compartment, a container, and a truck so as to cause supercooling, and install easily in the storage cabinet.
