Description

【0001】
【発明の属する技術分野】
本発明は、紫外線を利用して固形物や気体等の除菌対象物に付着又は浮遊しているウィルスや細菌やカビ等の微生物を殺菌及び除菌する紫外線を使用した除菌装置に関するものである。
【0002】
【従来の技術】
固形物に付着や含有されていたり、液体中や気体中に浮遊するウィルスや細菌やカビ等の微生物を除菌するのに紫外線照射を利用する方法が利用されている。
【0003】
この紫外線による殺菌及び除菌は、常温で行うことができ、しかも、あらゆる菌種、即ち、食中毒菌はもとより、結核菌、インフルエンザをはじめとする各種ウィルス、カビ等あらゆる微生物の殺菌に有効で、耐久菌を作らず、その上、照射対象物を変質させる心配が無く、コンパクトな設備で維持費が安価であるという特徴を有している。
【0004】
そのため、この紫外線照射を使用した除菌装置は、食品衛生上や医療関係や健康維持や精密機械や半導体分野等で、多く利用されており、この中に、食品加工工場、厨房、レストルーム、待合室、応接室、クリーンルーム等の室内の空気中に浮遊する菌を空気とともに装置内に吸い込み、内蔵された紫外線ランプの照射により殺菌して、殺菌後の空気を再び室内に戻す空気循環式の連続除菌システムがある。
【0005】
この連続除菌システムは、車載用の除菌装置や車両コンテナ用の除菌装置等にも使用され、青果物や生鮮品等の食品の運搬や倉庫等で利用されており、この除菌装置内に設けた通路内に空気を流通させると共に、この通路内を通過する空気に紫外線照射を行ない、除菌装置の外部には紫外線が漏れないように設計されている。
【0006】
【発明が解決しようとする課題】
しかしながら、これらの紫外線を使用した除菌装置においては、紫外線照射に低圧水銀ランプを使用して、安全で殺菌力の強い波長253.7nmの紫外線を照射して行っているが、この紫外線を効率的かつ効果的に照射する方法としては、継続的に照射するよりも、ある程度の間隔をおいて、照射を繰り返した方が良いとされている。
【0007】
この紫外線の照射と非照射の繰り返しは、従来技術の除菌装置では、紫外線照射ランプへの通電をON/OFF操作することによって行っているが、このON/OFF操作により、比較的高価な紫外線照射ランプの寿命が非常に短くなってしまうため、紫外線を使用する除菌装置の運転及び保守コストが上昇してしまうという問題がある。
【0008】
本発明は、上記の問題を解決するためになされたものであり、その目的は、紫外線照射ランプのON操作とOFF操作を繰り返すことなく、照射対象物に紫外線を間欠的に照射して効率よく除菌ができ、しかも、紫外線照射ランプの寿命を長く維持できる耐久性に優れた紫外線を使用した除菌装置を提供することにある。
【0009】
【課題を解決するための手段】
以上のような目的を達成するための紫外線を使用した除菌装置は、次のように構成される。
【0010】
1)除菌対象物を除菌室を通過させて、前記除菌室内に設けた紫外線照射ランプで紫外線を前記除菌対象物に照射することにより除菌する除菌装置において、前記除菌室を仕切り部材で、前記除菌対象物の移動方向に照射室と非照射室が交互に隣接するように区分し、前記除菌対象物を前記照射室と前記非照射室に移動させる移動手段を設けると共に、前記紫外線照射ランプを前記照射室に臨ませて設ける。
【0011】
この構成によれば、照射室と非照射室を交互に隣接して配置し、紫外線照射ランプを照射室に臨ませて配置して各照射室を照射すると共に、除菌対象物を移動させて、照射室と非照射室を交互に通過させることにより、紫外線照射ランプのON操作とOFF操作を繰り返したのと同様な効果が得られる。
【0012】
2)あるいは、除菌対象物を除菌室を通過させて、前記除菌室内に設けた紫外線照射ランプで紫外線を前記除菌対象物に照射することにより除菌する除菌装置において、前記除菌室を仕切り部材で、前記除菌対象物の移動方向に照射室と非照射室が交互に隣接するように区分し、前記除菌対象物を前記照射室と前記非照射室に移動させる移動手段を設けると共に、前記紫外線照射ランプを少なくとも一つの前記照射室と少なくとも一つの前記非照射室に臨ませ、更に、前記紫外線照射ランプの前記非照射室に臨む部分を遮光部材で遮光する。
【0013】
つまり、除菌対象物を除菌室に移動させる紫外線を使用した除菌装置において、例えば、1本乃至複数本の紫外線照射ランプの長手方向に延びる除菌室を設け、この除菌室に、紫外線照射ランプを横切るように仕切り部材を設けて、照射室,非照射室が交互に隣接するように、即ち、照射室,非照射室,照射室,・・・・となるように除菌室を区切る。
【0014】
そして、この非照射室に臨む紫外線照射ランプの部分を、遮光部材で覆って遮光し、非照射室では紫外線が照射されないようにし、除菌対象物を移動手段により移動させて、照射室と非照射室を交互に通過させて除菌する。
【0015】
この除菌対象物を移動させて、除菌対象物を照射室と非照射室を交互に通過させることにより、紫外線照射ランプのON操作とOFF操作を繰り返したのと同様な効果が得られ、一つの紫外線照射ランプを複数の照射室で使用することにより、各照射室ごとに紫外線照射ランプを設ける必要がなくなるので、全体としての紫外線照射ランプの数が少なくて済み装置が簡略化する。
【0016】
3)上記の紫外線を使用した除菌装置において、前記除菌対象物を気体とし、前記移動手段を通気ファンで形成する。
【0017】
この構成によれば、空気中に浮遊している微生物等の除菌が必要な、食料品運搬の荷物室内や車両コンテナ室内、病院内、厨房内等の空気を除菌できる。
【0018】
4)また、上記の気体を除菌対象物とする紫外線を使用した除菌装置において、前記仕切り部材を通風可能な仕切り板で形成し、該仕切り板に設ける通気用の開口穴を、該仕切り部材の板厚方向に対して傾斜して設ける。
【0019】
この構成によれば、紫外線照射ランプからの紫外線が照射室側から非照射室側へ漏れる量が少なくなり、遮光効果が上がり、これにより、照射と非照射の区分がより明確になる。
【0020】
以上の構成の紫外線を使用する除菌装置によれば、紫外線照射ランプに対して、ON及びOFFを繰り返す代わりに、除菌対象物が移動する除菌室を照射室と非照射室とに区切りに、除菌対象物が通過する一つおきの各照射室においては、紫外線照射ランプを露出させて紫外線を照射して、紫外線照射ランプのON操作と同じ効果を与え、この照射室の隣に位置する非照射室では、紫外線照射ランプを遮光部材で遮光して、紫外線照射ランプのOFF操作と同じ効果を与えることができる。
【0021】
従って、紫外線照射ランプのON操作とOFF操作の繰り返しが不要になり、この繰り返し操作による寿命の短縮化が防止され、耐久性が向上する。
【0022】
【発明の実施の形態】
以下、本発明の実施の形態について、除菌対象物を空気とし、移動手段を通気ファンとした、気体用の紫外線を使用した除菌装置を例にして、図面を用いながら説明する。
【0023】
図1〜図3に示すように、紫外線を使用した除菌装置1は、下部の通気穴5を有する底板1aと、側板1b,1bと、通気ファン7が設けられた通気口8を有する天井板1cと前板1dと後板1dとで箱状に形成され、通気ファン7を駆動することにより、外部の空気Aを底板1aの通気穴5から吸い込んで、天井板1cの通気口8から除菌された空気Acを吐き出すように構成される。
【0024】
この箱状に形成された除菌室2内に波長253.7nmの紫外線を放射する紫外線照射ランプ3を1本乃至複数本(図1〜図3では1本)取り付け、この除菌室2に仕切り板(仕切り部材)4a,4bを設け、図面の下側から第1除菌室2a,第2除菌室2b,第3除菌室2cを設ける。
【0025】
この時に、紫外線照射ランプ3は各仕切り板4a,4bを貫通して、各除菌室2a,2b,2cにその一部分3a,3b,3cが存在するように、即ち、各除菌室2a,2b,2cに臨むように配置される。
【0026】
そして、非照射室となる第2除菌室2bに臨む、紫外線照射ランプ3の部分3bを遮光部材6で遮光する。即ち、各除菌室2a,2b,2cを紫外線照射ランプ3の一部分3a,3cが露出する照射室2a,2cと、その隣の非照射室2bとして形成し、これらの照射室2a,2cと非照射室2bとは交互に隣接するように配置される。
【0027】
そして、更に、各除菌室2a,2b,2cの通風距離La,Lb,Lcをそれぞれ、通風速度を考慮しながら、殺菌効率の良い照射時間と非照射時間に対応させて設定して、この箱状の紫外線を使用した除菌装置1を構成する。
【0028】
この通風距離La,Lb,Lcは通常は、所定の照射時間と非照射時間に比例させて形成するが、より厳密に設定する場合は、各除菌室2a,2b,2cを空気Aが通過するのに要する時間がそれぞれの照射時間と非照射時間となるように設定し、更に、紫外線の照射量を勘案した補正を行うことになる。
【0029】
また、この紫外線を使用した除菌装置1では、紫外線照射ランプ3を複数の照射室2a,2bで使用するので、各照射室2a,2bごとに紫外線照射ランプ3を設ける必要がなくなり、装置が簡略化される。
【0030】
更に、この仕切り板4a,4bには、図4に示すように、通気穴5を板厚方向Zに対して傾斜角αi,αj・・・を有して傾斜させて開口し、照射室2a,2c側から非照射室2b側への紫外線に対する遮光効果を増大させる。
【0031】
この傾斜角αi,αj・・・は、加工を容易にするために全て同じ角度にしてもよく、あるいは、遮光効果を上げるために、通気穴5の位置によって別々の角度になるようにしてもよい。
【0032】
つまり、箱状の紫外線を使用する除菌装置1を、紫外線照射ランプ3を除菌室2内に配置すると共に、除菌室2をこの紫外線照射ランプ3を空気Aの移動方向に分割するように、通気穴5を有する遮光用の仕切り板4a,4bで仕切り、この仕切り板4a,4bの間に位置する非照射室である第2除菌室2bにおける紫外線照射ランプ3の一部分3bを遮光部材6で遮光して形成する。
【0033】
以上の構成により、第1除菌室2a,第2除菌室2b,第3除菌室2cを経由して移動して来る空気Aに対して、照射室である第1除菌室2aで紫外線を照射し、次の非照射室である第2除菌室2bでは、紫外線を照射することなく通過させ、また、照射室である第3除菌室2cで再び紫外線を照射してから、外部に送り出すことができる。
【0034】
従って、紫外線照射ランプ3をON操作したままで、流通する空気Aは、照射、非照射を繰り返して受けることになり、従来の紫外線を使用した除菌装置1における紫外線照射ランプ3のON操作とOFF操作の繰り返しと同じ効果を奏することができる。そのため、紫外線照射ランプ3のON操作とOFF操作の繰り返しによる寿命の短縮を避けることができる。
【0035】
この本発明の紫外線を使用した除菌装置は、生鮮品や食品等の貯蔵倉庫に適用することができるが、ユニット化したコンパクトな装置とすることができるため、貨物、トラック、船、航空貨物等の長距離輸送を行う車両等の荷物室やコンテナ室にも有効に適用することができる。
【0036】
【発明の効果】
以上説明したように、本発明に係る紫外線を使用する除菌装置によれば、紫外線照射ランプのON操作とOFF操作を繰り返す代わりに、除菌対象物が移動する除菌室を照射室と非照射室を隣接させて仕切り、照射室では、紫外線照射ランプを露出させて紫外線を照射し、紫外線照射ランプをON操作した時と同じ効果を与え、この照射室に隣接する非照射室においては、紫外線照射ランプを遮光部材で遮光して、紫外線照射ランプをOFF操作した時と同じ効果を与えることができる。
【0037】
従って、紫外線照射ランプ3のON操作とOFF操作の繰り返しが不要になり、このON操作とOFF操作の繰り返しによる寿命の短縮を回避することができるので、紫外線ランプの寿命を長く維持することができ、耐久性を向上させることができる。

[0005]
This continuous sterilization system is also used for in-vehicle sterilization devices, sterilization devices for vehicle containers, etc., and is used in the transportation and storage of foods such as fruits and vegetables and fresh products. The air is circulated through the passage provided in the air passage, and the air passing through the passage is irradiated with ultraviolet rays so that the ultraviolet rays do not leak outside the sterilization apparatus.
[0006]
[Problems to be solved by the invention]
However, in these sterilizers using ultraviolet rays, a low-pressure mercury lamp is used for ultraviolet irradiation, and ultraviolet rays having a wavelength of 253.7 nm, which is safe and has a strong sterilizing power, are irradiated. As a method of irradiating efficiently and effectively, it is said that it is better to repeat the irradiation with a certain interval than to continuously irradiate.
[0007]
This repetition of irradiation and non-irradiation of ultraviolet rays is performed by ON / OFF operation of the ultraviolet irradiation lamp in the sterilization apparatus of the prior art, but this ON / OFF operation causes relatively expensive ultraviolet rays. Since the life of the irradiation lamp becomes very short, there is a problem that the operation and maintenance cost of the sterilization apparatus using ultraviolet rays increases.
[0008]
The present invention has been made in order to solve the above-described problems, and the object thereof is to efficiently irradiate an irradiation object with ultraviolet rays intermittently without repeating the ON and OFF operations of the ultraviolet irradiation lamp. An object of the present invention is to provide a sterilization apparatus using ultraviolet rays that can be sterilized and that is excellent in durability and can maintain a long life of an ultraviolet irradiation lamp.
[0009]
[Means for Solving the Problems]
The sterilization apparatus using ultraviolet rays for achieving the above object is configured as follows.
[0010]

A partition member that divides the irradiation chamber and the non-irradiation chamber alternately in the moving direction of the sterilization target, and moves the sterilization target to the irradiation chamber and the non-irradiation chamber. And the ultraviolet irradiation lamp is provided facing the irradiation chamber.
[0011]
According to this configuration, the irradiation chamber and the non-irradiation chamber are alternately arranged adjacent to each other, the ultraviolet irradiation lamp is disposed facing the irradiation chamber to irradiate each irradiation chamber, and the sterilization target is moved. By alternately passing through the irradiation chamber and the non-irradiation chamber, the same effect as repeating the ON operation and OFF operation of the ultraviolet irradiation lamp can be obtained.
[0012]
2) Alternatively, in the sterilization apparatus for sterilization by passing the sterilization target through the sterilization chamber and irradiating the sterilization target with ultraviolet rays using an ultraviolet irradiation lamp provided in the sterilization chamber. Move the germ chamber with a partition member so that the irradiation chamber and the non-irradiation chamber are alternately adjacent to each other in the moving direction of the sterilization target, and move the sterilization target to the irradiation chamber and the non-irradiation chamber Means are provided, the ultraviolet irradiation lamp is exposed to at least one irradiation chamber and at least one non-irradiation chamber, and a portion of the ultraviolet irradiation lamp that faces the non-irradiation chamber is shielded by a light shielding member.
[0013]
That is, in the sterilization apparatus using ultraviolet light that moves the sterilization target to the sterilization chamber, for example, a sterilization chamber extending in the longitudinal direction of one or a plurality of ultraviolet irradiation lamps is provided. A partition member is provided so as to cross the ultraviolet irradiation lamp so that the irradiation chamber and the non-irradiation chamber are alternately adjacent, that is, the irradiation chamber, the non-irradiation chamber, the irradiation chamber, and so on. Is separated.
[0014]
The portion of the ultraviolet irradiation lamp that faces the non-irradiation chamber is covered with a light shielding member to block the light, so that ultraviolet rays are not irradiated in the non-irradiation chamber, and the sterilization target is moved by the moving means, so Sterilize by passing through the irradiation chamber alternately.
[0015]
By moving this sterilization target and passing the sterilization target alternately between the irradiation chamber and the non-irradiation chamber, the same effect as repeating the ON and OFF operations of the ultraviolet irradiation lamp can be obtained, By using one ultraviolet irradiation lamp in a plurality of irradiation chambers, it is not necessary to provide an ultraviolet irradiation lamp for each irradiation chamber, so that the number of ultraviolet irradiation lamps as a whole is reduced and the apparatus is simplified.
[0016]
3) In the sterilization apparatus using the above ultraviolet rays, the sterilization target is made into a gas, and the moving means is formed by a ventilation fan.
[0017]
According to this configuration, it is possible to sterilize air in a food product luggage compartment, a vehicle container room, a hospital, a kitchen, or the like that requires sterilization of microorganisms floating in the air.
[0018]
4) Further, in the sterilization apparatus using ultraviolet rays that uses the gas as a sterilization target, the partition member is formed of a partition plate that allows ventilation, and an opening hole for ventilation provided in the partition plate is provided in the partition. Inclined with respect to the plate thickness direction of the member.
[0019]
According to this configuration, the amount of ultraviolet light from the ultraviolet irradiation lamp leaking from the irradiation chamber side to the non-irradiation chamber side is reduced, and the light shielding effect is improved, thereby making the distinction between irradiation and non-irradiation more clear.
[0020]
According to the sterilization apparatus using ultraviolet rays having the above-described configuration, instead of repeating ON and OFF with respect to the ultraviolet irradiation lamp, the sterilization chamber in which the sterilization target object moves is divided into an irradiation chamber and a non-irradiation chamber. Furthermore, in every other irradiation chamber through which the object to be sterilized passes, the ultraviolet irradiation lamp is exposed and irradiated with ultraviolet rays, and the same effect as the operation of turning on the ultraviolet irradiation lamp is given. In the non-irradiation chamber located, the ultraviolet irradiation lamp can be shielded by the light blocking member, and the same effect as the operation of turning off the ultraviolet irradiation lamp can be provided.
[0021]
Accordingly, it is not necessary to repeat the ON operation and OFF operation of the ultraviolet irradiation lamp, and the shortening of the life due to the repeated operation is prevented, and the durability is improved.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings, taking as an example a sterilization apparatus using ultraviolet rays for gas, in which the sterilization target is air and the moving means is a ventilation fan.
[0023]
As shown in FIGS. 1 to 3, the sterilization apparatus 1 using ultraviolet rays includes a bottom plate 1 a having a lower vent hole 5, side plates 1 b and 1 b, and a ceiling 8 having a vent hole 8 provided with a ventilating fan 7. The plate 1c, the front plate 1d, and the rear plate 1d are formed in a box shape, and by driving the ventilation fan 7, the outside air A is sucked from the ventilation holes 5 of the bottom plate 1a, and then from the ventilation holes 8 of the ceiling plate 1c. It is configured to exhale sterilized air Ac.
[0024]
One or a plurality of ultraviolet irradiation lamps 3 (one in FIGS. 1 to 3) for emitting ultraviolet rays having a wavelength of 253.7 nm are attached to the sterilization chamber 2 formed in the box shape. Partition plates (partition members) 4a and 4b are provided, and a first sterilization chamber 2a, a second sterilization chamber 2b, and a third sterilization chamber 2c are provided from the lower side of the drawing.
[0025]
At this time, the ultraviolet irradiation lamp 3 passes through the partition plates 4a and 4b so that the sterilization chambers 2a, 2b and 2c have portions 3a, 3b and 3c, that is, the sterilization chambers 2a and 2c. It arrange | positions so that 2b, 2c may be faced.
[0026]
The portion 3 b of the ultraviolet irradiation lamp 3 facing the second sterilization chamber 2 b serving as a non-irradiation chamber is shielded by the light shielding member 6. That is, the sterilization chambers 2a, 2b, and 2c are formed as irradiation chambers 2a and 2c in which portions 3a and 3c of the ultraviolet irradiation lamp 3 are exposed, and non-irradiation chambers 2b adjacent to the irradiation chambers 2a and 2c. It arrange | positions so that the non-irradiation chamber 2b may adjoin alternately.
[0027]
Further, the ventilation distances La, Lb, Lc of the respective sterilization chambers 2a, 2b, 2c are set in correspondence with irradiation time and non-irradiation time with good sterilization efficiency, taking into consideration the ventilation speed. A sterilization apparatus 1 using box-shaped ultraviolet rays is configured.
[0028]
The ventilation distances La, Lb, and Lc are normally formed in proportion to a predetermined irradiation time and a non-irradiation time, but when set more strictly, the air A passes through the sterilization chambers 2a, 2b, and 2c. The time required for this is set to be the respective irradiation time and non-irradiation time, and further correction is performed in consideration of the irradiation amount of ultraviolet rays.
[0029]
Further, in the sterilization apparatus 1 using ultraviolet rays, since the ultraviolet irradiation lamp 3 is used in the plurality of irradiation chambers 2a and 2b, it is not necessary to provide the ultraviolet irradiation lamp 3 for each of the irradiation chambers 2a and 2b. Simplified.
[0030]
Further, as shown in FIG. 4, the partition plates 4a and 4b are opened with the ventilation holes 5 inclined with respect to the plate thickness direction Z with inclination angles αi, αj... , 2c side to the non-irradiation chamber 2b side is increased.
[0031]
These inclination angles αi, αj... May be all the same angle for easy processing, or may be different angles depending on the position of the vent hole 5 in order to increase the light shielding effect. Good.
[0032]
That is, in the sterilization apparatus 1 that uses box-shaped ultraviolet rays, the ultraviolet irradiation lamp 3 is disposed in the sterilization chamber 2, and the sterilization chamber 2 is divided into the movement direction of the air A. In addition, a part 3b of the ultraviolet irradiation lamp 3 in the second sterilization chamber 2b, which is a non-irradiation chamber located between the partition plates 4a and 4b, is partitioned by the light shielding partition plates 4a and 4b having the vent holes 5. The member 6 is formed so as to be shielded from light.
[0033]
With the above configuration, in the first sterilization chamber 2a which is an irradiation chamber with respect to the air A moving via the first sterilization chamber 2a, the second sterilization chamber 2b, and the third sterilization chamber 2c. In the second sterilization chamber 2b, which is the next non-irradiation chamber, it is allowed to pass through without irradiating ultraviolet rays, and in the third sterilization chamber 2c, which is the irradiation chamber, the ultraviolet rays are irradiated again, Can be sent to the outside.
[0034]
Therefore, the circulating air A is repeatedly irradiated and non-irradiated while the ultraviolet irradiation lamp 3 is turned on, and the ultraviolet irradiation lamp 3 is turned on in the conventional sterilization apparatus 1 using ultraviolet rays. The same effect as repeating the OFF operation can be obtained. For this reason, it is possible to avoid shortening the life due to the repetition of the ON operation and OFF operation of the ultraviolet irradiation lamp 3.
[0035]
The sterilization apparatus using ultraviolet rays according to the present invention can be applied to a storage warehouse for fresh products, foods, etc., but since it can be a unitized compact apparatus, cargo, truck, ship, air cargo The present invention can also be effectively applied to a luggage room or a container room of a vehicle or the like that performs long-distance transportation.
[0036]
【The invention's effect】
As described above, according to the sterilization apparatus using ultraviolet rays according to the present invention, instead of repeating the ON and OFF operations of the ultraviolet irradiation lamp, the sterilization chamber in which the sterilization target object moves is not the irradiation chamber. The irradiation chamber is adjacently divided, and in the irradiation chamber, the ultraviolet irradiation lamp is exposed to irradiate the ultraviolet ray, and the same effect as when the ultraviolet irradiation lamp is turned on is given. In the non-irradiation chamber adjacent to the irradiation chamber, The same effect as when the ultraviolet irradiation lamp is turned off by shielding the ultraviolet irradiation lamp with the light shielding member can be provided.
[0037]
