Description

【０００１】
【発明の属する技術分野】
本発明は、下吹き出しの冷凍サイクルを有する定温コンテナに係り、より詳細にはオゾン発生器とマイナスイオン発生器とを備えた定温コンテナに関する。
【０００２】
【従来の技術】
一般にクールコンテナといわれる定温コンテナは、生鮮品の長期鮮度保持のため、庫内を定温に保つことによって、生鮮品の生命活動（呼吸等）を抑えるようになっている。しかし、庫内を定温（例えば、５℃等の低温）に保っていても、低温で繁殖する菌類（かびや細菌）によって生鮮品の腐食が進行するといった問題や、菌類の繁殖による腐敗臭が生鮮品に付着するといった問題があった。
【０００３】
また、生鮮品の種類によっては、エチレンガスを発生するものもあり、自ら発生したエチレンガスによってさらに鮮度が劣化するといった問題もあった。この対策として、従来よりエチレンガス吸着剤を庫内に収納して鮮度低下を抑えていたが、エチレンガス吸着剤は生鮮品の搬送ごとにその都度回収して交換する必要があり、また、交換を忘れて使用し続けた場合には、袋が破れてビーズ状の吸着剤が庫内にこぼれ出るといった問題があった。
【０００４】
近時、このような生鮮品の衛生管理や鮮度を保つ手段として、定温コンテナにオゾン発生器とマイナスイオン発生器とを備えた生鮮品保存流通装置が提案されている（特開２００２−６８４２２号公報参照）。
【０００５】
【発明が解決しようとする課題】
ところで、オゾンは、空気中に漂ったり壁や生鮮品に付着している埃や菌類等に吸着することで酸化し、分解して滅菌するものであるが、電荷を持っていないので、近くに金属板などがあってもこれに影響されることはない。
【０００６】
一方、マイナスイオンは、互いに反発しあって空間に広がっていく空間拡散性を有する反面、狭い空間を通過すると急激に消耗される性質がある。また、金属板などが近傍にある場合にはこれに吸着されていまい、滅菌効果が期待できない。
【０００７】
従って、オゾン発生器やマイナスイオン発生器は、このような特性を考慮して設置する必要があるが、上記した従来の生鮮品保存流通装置ではこのような点が全く考慮されておらず、オゾン発生器とマイナスイオン発生器とが一体化された状態で同じ場所（庫内の天井部分）に取り付けられている。そのため、各機器の特性が最大限に発揮されているとはいえず、充分な滅菌効果が期待できないといった問題があった。
【０００８】
本発明は係る問題点を解決すべく創案されたもので、その目的は、オゾン発生器とマイナスイオン発生器の特性を充分考慮した配置とすることで、各機器の特性を最大限に生かした定温コンテナを提供することにある。
【０００９】
【課題を解決するための手段】
本発明の定温コンテナは、庫内にオゾン発生器とマイナスイオン発生器とを備えた定温コンテナにおいて、前記マイナスイオン発生器が、下吹き出しタイプの冷凍ユニットを有する庫内の天井部分であって前記冷凍ユニットから離れた場所に設置され、前記オゾン発生器が、庫内の天井部分であって前記冷凍ユニットの近傍に設置されていることを特徴としている。
【００１０】
このような特徴を有する本発明によれば、マイナスイオン発生器は、下吹き出しタイプの冷凍ユニットを有する庫内の天井部分であって冷凍ユニットから離れた場所に設置されている。具体的には、荷物（生鮮品）を積載した場合に生じる最大空間である荷物と天井の間の空間で、かつ冷凍ユニットの吸い込み口と反対の位置に設置される。マイナスイオンは、互いに反発しあって空間に広がっていく空間拡散性を有しているため、積載された生鮮品の上部空間に拡散しながら効果的に滅菌することになる。一方、マイナスイオンを吸着して消失させる金属板は、庫内では冷凍ユニットの熱交換機の部分に使用されている。そのため、本発明では、マイナスイオン発生器を冷凍ユニットから離れた場所に設置している。これにより、マイナスイオンの滅菌作用をより長く持続させることが可能となる。
【００１１】
一方、オゾンは、電荷を持たないため、近くに金属板などがあってもこれに影響されることなく、空気中に漂っている埃や菌類等、及び壁や生鮮品に付着している菌類等に作用する。従って、オゾン発生器を冷凍ユニットの近傍に設置することで、オゾン発生器の特性を充分に生かすことができる。
【００１２】
具体的な設置位置としては、冷凍ユニットが庫内の扉とは反対側の内奥部に設置されている場合には、オゾン発生器を冷凍ユニットの近傍の天井部分に設置し、マイナスイオン発生器を扉近傍の天井部分に設置する。
【００１３】
この場合、オゾン発生器は、冷凍ユニットの上部吸い込み口近傍に設置するのがよい。下吹き出しタイプの冷凍ユニットは、その構造上、空気の吸い込み口である上流側より、熱交換機内部や空気の吹き出し口である下流側の方に埃や細菌がたまりやすく、また空気中の水分も凝結してじめじめしている。そのため、オゾン発生器を冷凍ユニットの吸い込み口近傍に設置することで、濃度の高い状態のオゾンがすぐさま吸い込み口から冷凍ユニット内に吸入され、下流側の吹き出し口近傍で繁殖している細菌に作用して、これを滅菌することができる。すなわち、濃度の高い状態のオゾンを冷凍ユニットに直接作用させることができる。これにより、冷凍ユニット内の菌類による荷物（生鮮品）の汚染を防止することができる。
【００１４】
また、マイナスイオン発生器は、庫内の天井部分に埋め込むように設置する。これにより、扉を開けて生鮮品の積み下ろしを行うとき、マイナスイオン発生器が邪魔になることがない。
【００１５】
また、定温コンテナに冷凍ユニットを駆動する発電機用エンジンユニットを搭載している場合には、オゾン発生器及びマイナスイオン発生器の電源として、この発電機用エンジンユニットのＡＣ電源をそのまま使用する。従来のクールコンテナの場合、輸送用車両もクールコンテナも装備しているのはＤＣ電源のみである。そのため、オゾン発生器やマイナスイオン発生器を使用するためには、別にＤＣ／ＡＣ変換器を必要とするが、冷凍ユニットを駆動する発電機用エンジンユニットを搭載している場合には、このような不要な機器を新たに搭載するといった無駄を無くすことができる。
【００１６】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を参照して説明する。
【００１７】
図１は、本発明の定温コンテナの全体構成を示す側面より見た概略断面図である。
【００１８】
本実施の形態の定温コンテナ１は、例えば庫内１０の後部側（運転席とは反対側）に扉１１が設けられており、ここから生鮮品等の荷物Ａを搬入または搬出するようになっている。また、冷凍ユニット１２が、庫内１０の内奥部（運転席の背中側）に設置された構成となっている。
【００１９】
また、冷凍ユニット１２は、本実施の形態では下吹き出しタイプとなっている。すなわち、冷凍ユニット１２は、上部側に空気の吸い込み口１３が設けられており、下部側に空気の吹き出し口１４が設けられている。また、吸い込み口１３の下部近傍に冷却ファン１５が配置され、その下部近傍に熱交換機１６が配置されている。
【００２０】
吹き出し口１４から吹き出した冷風は、荷物Ａを床から浮かせて庫内１０に積載するための多条に配置されたレール２１の間を通って庫内奥側から扉１１側に流れ、その流れる途中において、積載された荷物Ａの間から上方に吹き出し、最上部の荷物Ａと庫内１０の天井２２との間の空間２３を通って庫内奥側、すなわち、冷凍ユニット１２の吸い込み口１３側に向かって流れることになる。
【００２１】
このような配置構成において、本実施の形態では、オゾン発生器３０を、冷凍ユニット１２の吸い込み口１３に対向するようにして、庫内１０の天井２２部分に設置し、マイナスイオン発生器４０を、扉１１近傍の天井２２部分に設置している。
【００２２】
これにより、オゾン発生器３０から発生したオゾンが、濃度の高い状態ですぐさま吸い込み口１３から冷凍ユニット１２内に吸い込まれ、熱交換機１６を通って、下流側の吹き出し口１４近傍で繁殖している細菌に作用し、これを滅菌することになる。
【００２３】
また、マイナスイオン発生器４０から発生したマイナスイオンは、積載された荷物Ａの上部空間２３を拡散しながら広がって行き、空間内に浮遊する埃や菌類を効果的に滅菌した後、冷凍ユニット１２の吸い込み口１３から吸い込まれて消失することになる。
【００２４】
なお、図１では、マイナスイオン発生器４０は庫内１０の天井２２から下部に露出した状態で取り付けられているが、扉１１の開閉時及び荷物Ａの積み下ろし時に邪魔にならないように、天井２２に埋め込むように設置するのがよい。
【００２５】
また、本実施の形態の定温コンテナでは、冷凍ユニットを駆動するための電源として、発電機用エンジンユニット５０を搭載している。従って、オゾン発生器３０及びマイナスイオン発生器４０の電源として、この発電機用エンジンユニット５０のＡＣ電源をそのまま使用することが可能である。
【００２６】
また、上記実施の形態では、下吹き出しタイプの冷凍ユニットを搭載した定温コンテナに本発明を適用しているが、上吹き出しタイプ（空気の流れが下吹き出しタイプと全く逆）の冷凍ユニットを搭載した定温コンテナに本発明を適用することが可能である。この場合、オゾン発生器やマイナスイオン発生器は、その特性を最大限に生かすためには、庫内１０の床面側に設置するのが好ましいが、天井側に設置することも可能である。。
【００２７】
【発明の効果】
本発明の定温コンテナによれば、マイナスイオン発生器を、下吹き出しの冷凍ユニットを有する庫内の天井部分であって冷凍ユニットから離れた場所に設置しているので、マイナスイオンの滅菌作用をより長く持続させることができ、また、積載された生鮮品の上部空間に拡散しながら効果的に滅菌することができる。
【００２８】
また、オゾン発生器を、冷凍ユニットの近傍、すなわち冷凍ユニットの吸い込み口近傍に設置しているので、温度の高い（すなわち、濃度の高い状態の）オゾンがすぐさま吸い込み口から冷凍ユニット内に吸入され、下流側の吹き出し口近傍で繁殖している細菌に作用して、これを効果的に滅菌することができる。すなわち、濃度の高い状態のオゾンを冷凍ユニットに直接作用させることができる。
【００２９】
また、マイナスイオン発生器を庫内の天井部分に埋め込むように設置しているので、扉を開けて生鮮品の積み下ろしを行うとき、マイナスイオン発生器が邪魔になることがない。
【００３０】
さらに、オゾン発生器及びマイナスイオン発生器の電源として、冷凍ユニットを駆動する発電機用エンジンユニットのＡＣ電源をそのまま使用しているので、オゾン発生器及びマイナスイオン発生器を駆動するために別途ＤＣ／ＡＣ変換器を搭載するといった無駄を無くすことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a constant temperature container having a refrigeration cycle of downward blowing, and more particularly to a constant temperature container provided with an ozone generator and a negative ion generator.
[0002]
[Prior art]
A constant-temperature container generally called a cool container suppresses the life activity (respiration, etc.) of the fresh product by keeping the inside of the refrigerator at a constant temperature in order to maintain the freshness of the fresh product for a long time. However, even if the inside of the refrigerator is kept at a constant temperature (for example, low temperature such as 5 ° C.), there is a problem that fungi (molds and bacteria) that propagate at a low temperature cause the corrosion of perishables to proceed, and a rotten smell due to the proliferation of fungi. There was a problem that it adhered to fresh products.
[0003]
In addition, some types of fresh products generate ethylene gas, and there is a problem that the freshness is further degraded by the ethylene gas generated by itself. As a countermeasure, ethylene gas adsorbents were conventionally stored in the refrigerator to prevent freshness from decreasing.However, ethylene gas adsorbents need to be collected and replaced each time fresh goods are transported. If the user forgets to use it and continues using it, there is a problem that the bag is broken and the bead-shaped adsorbent spills into the storage.
[0004]
Recently, as a means for maintaining hygiene and freshness of such fresh products, a fresh product storage and distribution device having an ozone generator and a negative ion generator in a constant temperature container has been proposed (JP-A-2002-68422). Gazette).
[0005]
[Problems to be solved by the invention]
By the way, ozone is oxidized by adsorbing on dust and fungi adhering to the walls and fresh goods, floating in the air, decomposing and sterilizing, but since it has no charge, it is close to The presence of a metal plate or the like is not affected by this.
[0006]
On the other hand, negative ions have a property of spatial diffusion, which repels each other and spreads into a space, but has a property of being rapidly consumed when passing through a narrow space. In addition, when a metal plate or the like is in the vicinity, it is adsorbed by the metal plate, and the sterilization effect cannot be expected.
[0007]
Therefore, it is necessary to install the ozone generator and the negative ion generator in consideration of such characteristics, but such a point is not considered at all in the above-mentioned conventional fresh food storage and distribution apparatus, The generator and the negative ion generator are integrated and attached to the same place (the ceiling in the refrigerator). For this reason, the characteristics of each device cannot be said to be maximized, and there has been a problem that a sufficient sterilizing effect cannot be expected.
[0008]
The present invention has been devised in order to solve such problems, and its purpose is to make the most of the characteristics of each device by arranging the characteristics of the ozone generator and the negative ion generator in consideration of the characteristics. To provide a constant temperature container.
[0009]
[Means for Solving the Problems]
The constant-temperature container of the present invention is a constant-temperature container provided with an ozone generator and a negative ion generator in the refrigerator, wherein the negative ion generator is a ceiling portion in the refrigerator having a downward-blowing type refrigeration unit, The ozone generator is installed at a location remote from the refrigerating unit, and the ozone generator is installed near the refrigerating unit at a ceiling portion in a refrigerator.
[0010]
According to the present invention having such a feature, the negative ion generator is installed at a location away from the refrigeration unit, which is a ceiling portion in a refrigerator having a refrigeration unit of the downward blowing type. Specifically, it is installed in a space between the luggage and the ceiling, which is the maximum space generated when luggage (perishables) is loaded, and at a position opposite to the suction port of the refrigeration unit. Since the negative ions have a spatial diffusivity that repels each other and spreads into the space, the negative ions are effectively sterilized while diffusing into the upper space of the loaded fresh product. On the other hand, a metal plate that adsorbs and eliminates negative ions is used for a heat exchanger of a refrigeration unit in the refrigerator. Therefore, in the present invention, the negative ion generator is installed at a place remote from the refrigeration unit. This makes it possible to maintain the sterilizing action of the negative ions for a longer time.
[0011]
On the other hand, ozone has no electric charge, so it is not affected by a nearby metal plate, so dust and fungi floating in the air, and fungi adhering to walls and fresh goods Act on etc. Therefore, by arranging the ozone generator near the refrigerating unit, the characteristics of the ozone generator can be fully utilized.
[0012]
As a specific installation position, if the refrigeration unit is installed on the inner back side opposite to the door inside the refrigerator, install the ozone generator on the ceiling near the refrigeration unit and generate negative ions. Place the vessel on the ceiling near the door.
[0013]
In this case, the ozone generator is preferably installed near the upper suction port of the refrigeration unit. Due to its structure, dust and bacteria are more likely to accumulate in the heat exchanger and on the downstream side, which is the air outlet, than on the upstream side, which is the air intake port. Congealed and damp. Therefore, by installing an ozone generator near the suction port of the refrigeration unit, high-concentration ozone is immediately sucked into the refrigeration unit from the suction port and acts on bacteria that are breeding near the downstream outlet. This can be sterilized. That is, ozone in a high concentration state can directly act on the refrigeration unit. This can prevent contamination of luggage (perishable goods) by fungi in the freezing unit.
[0014]
In addition, the negative ion generator is installed so as to be embedded in the ceiling portion of the refrigerator. Thus, when the door is opened and fresh products are loaded and unloaded, the negative ion generator does not interfere.
[0015]
When a constant temperature container is equipped with a generator engine unit for driving a refrigeration unit, the AC power supply of the generator engine unit is used as it is as the power source of the ozone generator and the negative ion generator. In the case of a conventional cool container, only the DC power supply is equipped with the transport vehicle and the cool container. Therefore, in order to use an ozone generator or a negative ion generator, a DC / AC converter is required separately. However, when an engine unit for a generator that drives a refrigeration unit is mounted, such a DC / AC converter is required. It is possible to eliminate waste such as newly installing unnecessary unnecessary devices.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0017]
FIG. 1 is a schematic sectional view showing the entire configuration of the constant temperature container of the present invention as viewed from a side.
[0018]
The constant temperature container 1 of the present embodiment is provided with a door 11 on the rear side of the compartment 10 (opposite to the driver's seat), for example, so that luggage A such as perishables can be loaded or unloaded therefrom. ing. In addition, the refrigeration unit 12 is configured to be installed inside the inside of the refrigerator 10 (at the back of the driver's seat).
[0019]
In the present embodiment, the refrigeration unit 12 is of a bottom blowing type. That is, the refrigerating unit 12 is provided with an air inlet 13 on the upper side and an air outlet 14 on the lower side. Further, a cooling fan 15 is arranged near a lower portion of the suction port 13, and a heat exchanger 16 is arranged near the lower portion.
[0020]
The cool air blown out from the outlet 14 flows between the rails 21 arranged in multiple rows for floating the luggage A from the floor and loading the luggage 10 in the storage 10, and flows from the back side of the storage to the door 11 side, and flows. On the way, the air blows upward from between the loaded luggage A and passes through the space 23 between the uppermost luggage A and the ceiling 22 of the refrigerator 10, that is, the suction port 13 of the refrigeration unit 12. It will flow toward the side.
[0021]
In this arrangement, in the present embodiment, the ozone generator 30 is installed on the ceiling 22 of the refrigerator 10 so as to face the suction port 13 of the refrigeration unit 12, and the negative ion generator 40 is , On the ceiling 22 near the door 11.
[0022]
Thereby, the ozone generated from the ozone generator 30 is immediately sucked into the refrigeration unit 12 from the suction port 13 in a high concentration state, and propagates through the heat exchanger 16 and near the downstream outlet 14. It will act on bacteria and sterilize it.
[0023]
Further, the negative ions generated from the negative ion generator 40 spread while spreading in the upper space 23 of the loaded baggage A, and after the dust and fungi floating in the space are effectively sterilized, the refrigeration unit 12 Will be sucked out from the suction port 13 and disappear.
[0024]
In FIG. 1, the negative ion generator 40 is installed so as to be exposed from the ceiling 22 of the inside of the compartment 10 at the lower portion. However, the ceiling 22 is not obstructed when the door 11 is opened and closed and when the load A is unloaded. It is good to be installed so as to be embedded in.
[0025]
In the constant temperature container of the present embodiment, a generator engine unit 50 is mounted as a power source for driving the refrigeration unit. Therefore, the AC power supply of the generator engine unit 50 can be used as it is as the power supply of the ozone generator 30 and the negative ion generator 40.
[0026]
Further, in the above embodiment, the present invention is applied to the constant temperature container equipped with the lower-blowing type refrigeration unit, but the upper-blowing type (air flow is completely opposite to the lower-blowing type) refrigeration unit is mounted. The present invention can be applied to a constant temperature container. In this case, the ozone generator and the negative ion generator are preferably installed on the floor side of the interior 10 in order to make the most of their characteristics, but they can also be installed on the ceiling side. .
[0027]
【The invention's effect】
According to the constant temperature container of the present invention, the negative ion generator is installed at a location away from the refrigeration unit, which is a ceiling portion of the inside of the refrigerator having the refrigeration unit of the downward blowing, so that the negative ion sterilizing action is more improved. It can be long lasting and can be effectively sterilized while spreading into the headspace of the loaded perishables.
[0028]
Further, since the ozone generator is installed near the refrigeration unit, that is, near the suction port of the refrigeration unit, high-temperature (that is, high-concentration) ozone is immediately sucked into the refrigeration unit from the suction port. It acts on bacteria growing near the downstream outlet, and can be effectively sterilized. That is, ozone in a high concentration state can directly act on the refrigeration unit.
[0029]
In addition, since the negative ion generator is installed so as to be embedded in the ceiling portion of the inside of the refrigerator, the negative ion generator does not interfere when the door is opened and fresh products are loaded and unloaded.
[0030]
Furthermore, since the AC power supply of the engine unit for the generator that drives the refrigeration unit is used as it is as the power supply for the ozone generator and the negative ion generator, a separate DC power supply is required to drive the ozone generator and the negative ion generator. / AC converter can be eliminated.
