Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and repeated descriptions are omitted as appropriate. Moreover, the dimensional ratio of each component in each drawing does not necessarily match the dimensional ratio of the actual ultraviolet irradiation device. Moreover, the structure described below is an illustration and does not limit the scope of the present invention at all.
図１は、本実施の形態に係る紫外線照射装置の概略構成の断面図である。図１に示す紫外線照射装置１０は、開口部１２を有する筐体１４と、筐体１４に設けられた把持部１５と、筐体１４の内部に設けられており、紫外線Ｌを発する紫外線発生部としての複数のＬＥＤ１６と、筐体１４の内部に設けられており、筐体内に風を生じさせる風発生部１８と、を備える。紫外線照射装置１０は、把持部１５をユーザが掴んで、殺菌対象である床やベッド、家具等まで移動することで、簡便に紫外線照射による殺菌ができる。
FIG. 1 is a cross-sectional view of a schematic configuration of an ultraviolet irradiation apparatus according to the present embodiment. An ultraviolet irradiation device 10 shown in FIG. 1 includes a housing 14 having an opening 12, a grip 15 provided in the housing 14, and an ultraviolet generator that emits ultraviolet light L provided inside the housing 14. And a plurality of LEDs 16 and a wind generator 18 that is provided inside the housing 14 and generates wind in the housing. The ultraviolet irradiation device 10 can be easily sterilized by ultraviolet irradiation by the user grasping the grip 15 and moving to the floor, bed, furniture or the like to be sterilized.
開口部１２は、紫外線Ｌが照射される照射対象としてのカーペット２０が配置されるように設けられている。アレイ状に配列された複数のＬＥＤ１６のそれぞれは、開口部１２に向けて紫外線Ｌを照射するように配置されている。これにより、カーペット２０に対するムラの少ない紫外線照射が可能となる。少ない風発生部１８は、カーペット２０に当たる風を生じさせるように構成されている。
The opening 12 is provided so that the carpet 20 as an irradiation target irradiated with the ultraviolet ray L is disposed. Each of the plurality of LEDs 16 arranged in an array is arranged so as to irradiate ultraviolet rays L toward the opening 12. Thereby, ultraviolet irradiation with little unevenness to the carpet 20 is possible. The few wind generation parts 18 are comprised so that the wind which hits the carpet 20 may be produced.
紫外線Ｌが照射される照射対象がカーペット２０のような起毛性（パイル２０ａ）の生地の場合、その隙間に入り込んだウイルスには直接紫外線Ｌが届かない領域がある。そこで、本実施の形態に係る紫外線照射装置１０は、開口部１２に配置されたカーペット２０に対して風Ｗを当てることで、カーペット２０に付着していたウイルスのような殺菌対象が移動し、それまで紫外線Ｌが届かないところに存在していたウイルスに対しても紫外線Ｌを照射することができる。その結果、殺菌効果の高い紫外線照射装置１０を実現できる。
When the irradiation target irradiated with the ultraviolet ray L is a raised fabric (pile 20a) such as the carpet 20, there is a region where the ultraviolet ray L does not reach the virus that has entered the gap. Therefore, the ultraviolet irradiation device 10 according to the present embodiment moves the sterilization target such as a virus attached to the carpet 20 by applying the wind W to the carpet 20 arranged in the opening 12. It is possible to irradiate the virus L which has existed in a place where the ultraviolet ray L has not reached before. As a result, the ultraviolet irradiation device 10 having a high sterilizing effect can be realized.
開口部１２は、カーペット２０で閉塞されるように周囲の端面１４ａが全周にわたり平坦になるように形成されている。また、端面１４ａは、カーペット２０に筐体１４を押し付けた際に筐体内部のウイルスが外部に漏れ出さないように、照射対象の形状に追従しやすい弾力性のある密着部材で構成されているとよい。密着部材は、例えば、ウイルスが通らないが空気は通す可撓性のフィルターやゴムである。これにより、カーペット２０に付着していたウイルスが風Ｗにより開口部１２から外部へ飛散することを抑制できる。
The opening 12 is formed so that the peripheral end surface 14a is flat over the entire circumference so as to be blocked by the carpet 20. Further, the end face 14a is configured by an elastic close-contact member that easily follows the shape of the irradiation target so that viruses inside the casing do not leak outside when the casing 14 is pressed against the carpet 20. Good. The contact member is, for example, a flexible filter or rubber that does not allow virus to pass but allows air to pass. Thereby, it can suppress that the virus adhering to the carpet 20 is scattered outside from the opening part 12 by the wind W.
開口部１２を囲む筐体１４の内壁１４ｂは、紫外線Ｌを開口部１２に向けて反射する反射部１４ｃを有している。反射部１４ｃは、例えば、純アルミニウム（ＪＩＳ１０００番台）の表面を電解研磨したものが好ましい。このように構成された反射部１４ｃは、紫外線を効率良く反射できるため、紫外線が無駄なく照射対象に照射される。
The inner wall 14b of the housing 14 surrounding the opening 12 has a reflecting portion 14c that reflects the ultraviolet light L toward the opening 12. The reflecting portion 14c is preferably, for example, one obtained by electropolishing the surface of pure aluminum (JIS 1000 series). Since the reflection part 14c comprised in this way can reflect an ultraviolet-ray efficiently, an ultraviolet-ray is irradiated to irradiation object without waste.
また、筐体１４の内壁１４ｂは、酸化チタンが塗布されていてもよい。酸化チタンは紫外線の照射により活性酸素を生じるため、消臭やウイルスの殺菌を更に効率良く行える。
Further, the inner wall 14b of the housing 14 may be coated with titanium oxide. Titanium oxide generates active oxygen when irradiated with ultraviolet rays, so deodorization and virus sterilization can be performed more efficiently.
風発生部１８は、ファンと、ファンが発する風の向きを変える風向変更機構と、を有している。風向変更機構は、例えば、扇風機の首振り機構や空調機のルーバー機構である。これにより、カーペット２０の広い範囲に対して、風Ｗを一様に当てることができる。また、ファンの向きは、カーペット２０に対して上方から直接吹き当てる向きが好ましい。また、風発生部１８が発生させる風は、カーペット２０に直接向かう旋回流が好ましい。これにより、パイル２０ａ自体を動かし、紫外線が直接届きにくいパイル２０ａの根本部分に存在するウイルスを殺菌できる。
The wind generator 18 has a fan and a wind direction changing mechanism that changes the direction of the wind generated by the fan. The wind direction changing mechanism is, for example, a swing mechanism of a fan or a louver mechanism of an air conditioner. Thereby, the wind W can be uniformly applied to a wide range of the carpet 20. Further, the direction of the fan is preferably such that it is directly blown against the carpet 20 from above. The wind generated by the wind generating unit 18 is preferably a swirl flow directly toward the carpet 20. Thereby, the pile 20a itself can be moved and the virus which exists in the root part of the pile 20a to which an ultraviolet-ray cannot reach directly can be disinfected.
本実施の形態に係るＬＥＤ１６は、ピーク波長が２５０～３００ｎｍの範囲、好ましくは２６０～２９０ｎｍの範囲にある紫外線を発する。一般的にはウイルスの不活化には波長が短い紫外線が有効であるが、波長が短い紫外線は樹脂や繊維のような有機物を劣化させることがある。そこで、ピーク波長が２５０～３００ｎｍの範囲にあるＬＥＤ１６を用いることで、ウイルスを不活化するとともに、カーペット２０が紫外線で劣化することを抑制できる。
The LED 16 according to the present embodiment emits ultraviolet rays having a peak wavelength in the range of 250 to 300 nm, preferably in the range of 260 to 290 nm. In general, ultraviolet rays having a short wavelength are effective for inactivating viruses, but ultraviolet rays having a short wavelength may deteriorate organic substances such as resins and fibers. Therefore, by using the LED 16 having a peak wavelength in the range of 250 to 300 nm, it is possible to inactivate the virus and suppress the carpet 20 from being deteriorated by ultraviolet rays.
筐体１４は、開口部１２とＬＥＤ１６との間に、風発生部１８が生じさせた風Ｗがカーペット２０に当たることでカーペット２０（パイル２０ａ）から離間したウイルスを紫外線Ｌで殺菌する殺菌室２２が設けられている。これにより、カーペット２０から離間したウイルスを効率良く殺菌できる。
The housing 14 sterilizes the virus separated from the carpet 20 (pile 20a) with ultraviolet light L when the wind W generated by the wind generating unit 18 strikes the carpet 20 between the opening 12 and the LED 16. Is provided. Thereby, the virus spaced apart from the carpet 20 can be sterilized efficiently.
筐体１４は、殺菌室２２の開口部１２がある側とは反対側の領域に予備室２４が設けられている。風発生部１８は、殺菌室２２と予備室２４とを隔てる隔壁部２６に設けられている。予備室２４は、風発生部１８を経由して殺菌室２２から流入したウイルスに紫外線を照射する予備ＬＥＤ２８が、隔壁部３０に設けられている。
The casing 14 is provided with a spare chamber 24 in a region opposite to the side where the opening 12 of the sterilization chamber 22 is located. The wind generator 18 is provided in a partition wall 26 that separates the sterilization chamber 22 and the reserve chamber 24. In the preliminary chamber 24, a preliminary LED 28 for irradiating the virus flowing from the sterilization chamber 22 via the wind generation unit 18 with ultraviolet rays is provided in the partition wall 30.
これにより、予備室２４に流入したウイルスも殺菌できる。なお、予備ＬＥＤ２８が発する紫外線Ｌ’は、隔壁部２６に照射され、カーペット２０に届かない。そのため、カーペット２０の劣化を考慮せずに予備ＬＥＤ２８が発する紫外線の波長を設定できる。換言すると、殺菌室２２に設けられているＬＥＤ１６が発する紫外線Ｌのピーク波長よりも短く、ウイルスの不活化により効果が高い波長の紫外線を発する予備ＬＥＤ２８を選択できる。このように、殺菌室２２に加えて予備室２４でもウイルスに紫外線を照射することで、ウイルスを確実に不活化できる。
Thereby, the virus that has flowed into the reserve chamber 24 can be sterilized. The ultraviolet light L ′ emitted from the spare LED 28 is irradiated on the partition wall portion 26 and does not reach the carpet 20. Therefore, it is possible to set the wavelength of ultraviolet rays emitted from the spare LED 28 without considering the deterioration of the carpet 20. In other words, it is possible to select a spare LED 28 that emits ultraviolet light having a wavelength shorter than the peak wavelength of the ultraviolet light L emitted from the LED 16 provided in the sterilization chamber 22 and having a high effect due to virus inactivation. In this manner, the virus can be reliably inactivated by irradiating the virus with ultraviolet rays in the preliminary chamber 24 in addition to the sterilization chamber 22.
予備室２４は、殺菌室２２に対して正圧になるように構成されている。具体的には、不図示のコンプレッサにより予備室２４内を殺菌室２２に対して正圧に維持している。これにより、殺菌室２２から予備室２４へウイルスが侵入しにくくなり、殺菌室２２でウイルスを効率良く殺菌できる。
The preliminary chamber 24 is configured to have a positive pressure with respect to the sterilization chamber 22. Specifically, the inside of the preliminary chamber 24 is maintained at a positive pressure with respect to the sterilization chamber 22 by a compressor (not shown). This makes it difficult for viruses to enter the sterilization chamber 22 from the sterilization chamber 22, and the virus can be efficiently sterilized in the sterilization chamber 22.
隔壁部２６の殺菌室２２側の表面には、アルミニウムからなる反射部材２６ａが設けられている。また、隔壁部２６の予備室２４側の表面には、アルミニウムからなる反射部材２６ｂが設けられている。なお、反射部材としては、紫外線の反射率が高いものであればよく、例えば、ＰＴＦＥであってもよい。これにより、殺菌室２２および予備室２４の空間内において、ウイルスに対して紫外線が効率良く照射される。なお、隔壁部３０の予備ＬＥＤ２８が搭載されている側と反対側の領域３２には、風発生部１８の動作、ＬＥＤ１６および予備ＬＥＤ２８の点消灯を制御する制御部３４が配置されている。
A reflecting member 26a made of aluminum is provided on the surface of the partition wall 26 on the sterilization chamber 22 side. Further, a reflecting member 26b made of aluminum is provided on the surface of the partition wall 26 on the side of the preliminary chamber 24. In addition, as a reflection member, what is necessary is just a high reflectance of an ultraviolet-ray, for example, PTFE may be sufficient. Thereby, ultraviolet rays are efficiently irradiated to the virus in the space of the sterilization chamber 22 and the spare chamber 24. In the region 32 on the opposite side of the partition wall 30 from the side where the spare LED 28 is mounted, a control unit 34 for controlling the operation of the wind generator 18 and turning on / off the LED 16 and the spare LED 28 is disposed.

前述の紫外線照射装置１０は、殺菌室２２以外に予備室２４が設けられているが、予備室がない構成であってもよい。その場合、風発生部１８は、殺菌室２２内に対流を起こすように配置すれば、殺菌室２２から空気が外部へ漏れ出る心配がない。 (Modification)
Theultraviolet irradiation device 10 described above is provided with the spare chamber 24 in addition to the sterilization chamber 22, but may have a configuration without the spare chamber. In that case, if the wind generator 18 is arranged so as to cause convection in the sterilization chamber 22, there is no fear that air will leak out of the sterilization chamber 22.
