Description

鮮度保持装置Freshness keeping device
　本発明は、生鮮物を収容してその鮮度を保持する鮮度保持装置に関する。 The present invention relates to a freshness-maintaining device for accommodating fresh food and maintaining its freshness.
　生鮮物を収容してその鮮度を保持する鮮度保持装置として、例えば特許文献１に記載の冷蔵又は冷凍コンテナや特許文献２に記載の鮮度保持コンテナ装置が知られている。 As a freshness-maintaining device for accommodating fresh food and maintaining its freshness, for example, a refrigerated or frozen container described in Patent Document 1 and a freshness-maintaining container device described in Patent Document 2 are known.
　特許文献１に記載の冷蔵又は冷凍コンテナでは、農産物や生鮮品等の生鮮物が収納されるコンテナ内の酸素濃度及びエチレン濃度をガス管理システムでコントロールするとともに、生鮮物の乾燥を湿度管理システムで防ぐことにより、生鮮物の呼吸、蒸散及びエチレンによる劣化を防止している。 In the refrigerated or frozen container described in Patent Document 1, the oxygen concentration and the ethylene concentration in the container in which fresh foods such as agricultural products and fresh foods are stored are controlled by a gas control system, and the drying of fresh foods is controlled by a humidity control system. By preventing it, perishables are prevented from breathing, evaporating and deteriorating due to ethylene.
　また、特許文献２に記載の鮮度保持コンテナ装置では、青果、花卉、魚介類、肉類等の生鮮物が収容されるコンテナ内における雰囲気ガスの強制流通路に連通、介在又は面する放電空間をプラズマ生成部が形成することにより、雰囲気ガス中のエチレン等の成長ホルモンを分解したり雰囲気ガス中の浮遊細菌を殺菌したりして、生鮮物の鮮度劣化を抑制している。 Further, in the freshness-preserving container device described in Patent Document 2, a discharge space that communicates with, intervenes, or faces a forced flow passage of atmospheric gas in a container in which fresh foods such as fruits and vegetables, flowers, fish and shellfish, and meat are housed is plasma. By forming the generation part, growth hormones such as ethylene in the atmosphere gas are decomposed and airborne bacteria in the atmosphere gas are sterilized, thereby suppressing deterioration of freshness of fresh food.

　ところで、生鮮物の鮮度保持機能を高めるのであれば、特許文献２に記載のように高周波電界を形成しつつ（特許文献２の段落００３８）、特許文献１に記載のように積極的にエチレン濃度を下げて加湿することが望ましいが、特許文献１では、窒素水による加湿や窒素水の噴霧を生鮮物の上方から直接的に行うので（特許文献１の段落００４４乃至００４７、図１）、生鮮物が湿り過ぎることがないように生鮮物の大きさや収容量によって加湿方法を調整しなければならないほか、エチレン濃度を下げるために窒素ガスをコンテナ内に注入してコンテナ内の既存の空気を通気口から排出させるので（特許文献１の段落００３４）、加湿した空気も通気口から排出されるという問題がある。 By the way, in order to enhance the freshness-maintaining function of fresh products, while forming a high-frequency electric field as described in Patent Document 2 (paragraph 0038 of Patent Document 2), the ethylene concentration is positively described in Patent Document 1. However, in Patent Document 1, humidification with nitrogen water and spraying of nitrogen water are performed directly from above the fresh product (paragraphs 0044 to 0047 of Patent Document 1, FIG. 1). The humidification method must be adjusted according to the size and capacity of the fresh food so that the food does not get too wet, and nitrogen gas is injected into the container to ventilate the existing air inside the container in order to reduce the ethylene concentration. Since it is discharged from the mouth (paragraph 0034 of Patent Document 1), there is a problem that humidified air is also discharged from the vent.
　また、水の使用には一般に雑菌が伴い、窒素水に雑菌が含まれていると、特に生鮮物が食品の場合には好ましくない。特許文献２には、プラズマによる雰囲気ガス中の浮遊細菌の殺菌に言及があるが（特許文献２の段落０００７）、湿気の高い空気をどのように効率的に殺菌するかについては開示されていない。 In addition, the use of water is generally accompanied by various germs, and if the nitrogen water contains germs, it is not preferable especially when the fresh food is food. Patent Document 2 mentions the sterilization of airborne bacteria in atmospheric gas by plasma (paragraph 0007 of Patent Document 2), but does not disclose how to efficiently sterilize humid air. ..
　本発明は、上記の事情に鑑みてなされたもので、生鮮物に電界を付与しつつ空気のエチレン除去及び加湿を行うことができ、その加湿を生鮮物に対する直接的な噴霧等によらず清潔に行うことができる鮮度保持装置を提供することを課題としている。 The present invention has been made in view of the above circumstances, and can remove ethylene and humidify air while applying an electric field to the fresh food, and the humidification is clean without direct spraying on the fresh food. The challenge is to provide a freshness-maintaining device that can be used in the above.
　上記課題を解決するために、本発明に係る鮮度保持装置は、生鮮物が収容される冷蔵又は冷凍の収容庫と、前記収容庫の庫内に電界を生成する電界生成手段と、前記庫内に設けられて前記庫内の空気を調整する空調手段とを備え、前記空調手段は、箱状の筐体と、前記筐体に設けられた吸込口及び吹出口と、前記吸込口の近傍に設けられたエチレンガス分解フィルタと、前記筐体の内部に設けられて前記吸込口及び前記吹出口を連通させる風路と、前記風路に回転可能に設けられたファンと、前記風路において前記ファンよりも前記吹出口の側に設けられた加湿手段と、前記風路において前記加湿手段よりも前記吹出口の側に設けられた除菌手段とを備え、前記ファンの回転により、前記庫内の空気は、前記吸込口から前記エチレンガス分解フィルタを通過して前記風路に吸い込まれ、前記ファンを通過して前記加湿手段で加湿された後に前記除菌手段で除菌され、前記吹出口から吹き出されることを特徴とする。 In order to solve the above problems, the freshness-maintaining device according to the present invention includes a refrigerated or frozen storage in which fresh foods are stored, an electric field generating means for generating an electric field in the storage, and the inside of the storage. The air-conditioning means is provided in the box-shaped housing, the suction port and the air outlet provided in the housing, and the vicinity of the suction port. An ethylene gas decomposition filter provided, an air passage provided inside the housing to communicate the suction port and the air outlet, a fan rotatably provided in the air passage, and the above in the air passage. The humidifying means provided on the side of the air outlet with respect to the fan and the disinfecting means provided on the side of the air outlet with respect to the humidifying means in the air passage are provided, and the inside of the refrigerator is caused by the rotation of the fan. The air from the suction port passes through the ethylene gas decomposition filter, is sucked into the air passage, passes through the fan, is humidified by the humidifying means, and then is sterilized by the sterilizing means, and is sterilized by the sterilizing means. It is characterized by being blown out from.
　前記吸込口及び前記吹出口は、前記筐体の前面に設けられていてもよい。 The suction port and the air outlet may be provided on the front surface of the housing.
　また、前記加湿手段は、前記風路の壁面に沿って形成された貯水槽と、前記貯水槽に貯水された水を吸収する加湿エレメントとを備えていてもよい。 Further, the humidifying means may include a water storage tank formed along the wall surface of the air passage and a humidifying element that absorbs the water stored in the water storage tank.
　さらに、前記除菌手段は、前記風路の壁面に塗布された光触媒と、前記光触媒に向けて発光する光源とを備えていてもよい。 Further, the sterilization means may include a photocatalyst applied to the wall surface of the air passage and a light source that emits light toward the photocatalyst.
　本発明によれば、生鮮物に電界を付与しつつ空気のエチレン除去及び加湿を行うことができ、その加湿を生鮮物に対する直接的な噴霧等によらず清潔に行うことができる鮮度保持装置を提供することができる。 According to the present invention, there is a freshness-maintaining device capable of removing ethylene from air and humidifying the fresh food while applying an electric field to the fresh food, and performing the humidification cleanly without directly spraying the fresh food. Can be provided.

Fresh food is placed and housed on the metal shelf 5, and the air conditioner 6 is placed and installed. In FIG. 1, the air conditioner 6 is installed on the right end side of the metal shelf 5 in the X direction and faces the Y direction, but the installation position and the installation direction are not limited, and is shown in FIG. 2, for example. As described above, the air conditioner 6 may be installed on the left end side in the Y direction and face the X direction.
　図３乃至図６に示すように、空調装置６は、箱状の筐体７と、筐体７に設けられた吸込口８及び吹出口９とを備える。 As shown in FIGS. 3 to 6, the air conditioner 6 includes a box-shaped housing 7, a suction port 8 and an air outlet 9 provided in the housing 7.
　筐体７は、直方体状を呈して前面１０、後面１１、天面１２、底面１３及び側面１４，１５を有し、前面１０の上部には開閉可能な扉１６が設けられ、吹出口９は扉１６に形成されている。 The housing 7 has a rectangular parallelepiped shape and has a front surface 10, a rear surface 11, a top surface 12, a bottom surface 13, and side surfaces 14, 15, and a door 16 that can be opened and closed is provided on the upper portion of the front surface 10, and the outlet 9 is provided.
