Description

本発明は紫外線照射空気殺菌装置に関し、特に、建物の内部空間に配備される紫外線照射空気殺菌装置に関する。 The present invention relates to an ultraviolet irradiation air sterilizer, and more particularly to an ultraviolet irradiation air sterilizer installed in the interior space of a building.

特許文献１は紫外線照射空気殺菌装置に関するもので、発明の課題は、「コンパクトで、殺菌する空気の流速が、低速から高速まで、広い流速の範囲で効率良く殺菌できる紫外線照射空気殺菌装置の提供こと」であり、複数個の発明の内、その請求項４には、図７と共に、ダクト４の内部の入口付近と出口付近に空気の蛇行流路を形成するように、長さが大小の平板状の遮光板７、７、７を、所定間隔を有して配設する技術が記載されている。 Patent document 1 relates to an ultraviolet irradiation air sterilizer, and the problem of the invention is "to provide an ultraviolet irradiation air sterilizer that is compact and can efficiently sterilize in a wide range of air flow speeds from low speed to high speed to be sterilized. Among a plurality of inventions, claim 4 includes, together with FIG. A technique is described in which flat light shielding plates 7, 7, 7 are arranged at predetermined intervals.

すなわち、特許文献１の空気殺菌装置には、「２分割されたダクト７の内部の上部ダクト４ａと下部ダクト４ｂのそれぞれの空間であって、前記ダクト４の入口側の吸入用ファン５ａが設置される位置の直ぐ後流側の空間部分及び前記ダクトの出口側の吸出用ファン５ｂが設置される位置の直ぐ上流側の空間部分に、複数枚の長短２種類の平板状の遮光板７が、前記ダクトの軸方向と直交する方向に指向し、かつ、軸方向に隣り合う遮光板７、７間に所定の間隔を置いて、空気の蛇行流路が形成されるような態様にしてそれぞれ設けられている（符号は特許文献１に記載のもの）。」
この特許文献１に記載の発明は、ダクトの内部を蛇行状に流れる空気を殺菌するという限りでは本発明の課題と一致する。しかしながら、特許文献１の発明は、次に列挙するような問題点がある。
（ａ）殺菌する空気の流速が、低速から高速まで、広い流速の範囲で効率良く殺菌できることを目的とするため、ダクトの両端開口部にそれぞれファンを取付けなければならない。
（ｂ）ダクト４の内部の入口付近と出口付近に空気の蛇行流路を形成するように設けられた長さが大小の遮光板７は、肌がやけどしにいように、すなわち、主にダクトの内部に設けた紫外線ランプ６からの紫外線がダクトの出入り口から漏れないようにするためである。すなちわ、複数枚の長短２種類の平板状の遮光板７は、ダクトに入り込んだ空気を所要時間、例えば３０秒以上の長い時間ダクトの内部に留まるようにするものではない。
（ｃ）ダクトの内部には、軸方向に隣会う平面視Ｘ状に配設された殺菌用導風板が多数存在するが、該殺菌用導風板の構造は複雑であり、組合せが面倒であると共に、製造コストが高くなる。
（ｄ）１本の紫外線ランプをダクトの中心部に、その軸方向にだけ配設しいる構造なので、空気の流速が低速か高速か如何にかかわらず、紫外線ランプから照射された直進的性質を有する紫外線（ＵＶ－Ｃ）が、各殺菌用導風板の間の空間部分の隅まで十分に当たらない。それ故、空気の殺菌を確実に行うことができるかどうか疑問である。 That is, in the air sterilizer of Patent Document 1, "a suction fan 5a on the inlet side of the duct 4 is installed in each space of the upper duct 4a and the lower duct 4b inside the duct 7 divided into two. A plurality of flat light shielding plates 7 of two types, long and short, are placed in the space immediately downstream of the position where the suction fan 5b is installed and in the space immediately upstream of the position where the suction fan 5b on the exit side of the duct is installed. , oriented in a direction perpendicular to the axial direction of the duct, and spaced apart from each other by a predetermined interval between the light shielding plates 7, 7 adjacent in the axial direction. provided (reference numerals are those described in Patent Document 1)."
The invention described in Patent Document 1 is consistent with the subject of the present invention as far as it sterilizes the air flowing meanderingly inside the duct. However, the invention of Patent Document 1 has the following problems.
(a) In order to achieve efficient sterilization over a wide range of flow velocities, from low to high, fans must be attached to the openings at both ends of the duct.
(b) The shading plates 7 with large and small lengths provided to form meandering flow paths of air near the inlet and outlet inside the duct 4 are designed to prevent skin burns, that is, mainly This is to prevent the ultraviolet rays from the ultraviolet lamp 6 provided inside the duct from leaking from the doorway of the duct. In other words, the plurality of flat plate-shaped light shielding plates 7 of two types, long and short, do not allow the air that has entered the duct to stay inside the duct for a long time, for example, 30 seconds or more.
(c) Inside the duct, there are many sterilizing baffle plates arranged in an X-shape in plan view, which are adjacent to each other in the axial direction. At the same time, the manufacturing cost increases.
(d) Since it is a structure in which one ultraviolet lamp is arranged in the center of the duct only in its axial direction, regardless of whether the air flow speed is low or high, the straight properties of the ultraviolet lamp irradiated from the ultraviolet lamp UV rays (UV-C) do not reach the corners of the space between the sterilizing baffle plates. It is therefore questionable whether air sterilization can be ensured.

特許文献２に記載の発明は、空気中の細菌やウイルスを、紫外線（ＵＶ－Ｃ）を照射して殺し、清浄化された空気を器外に排出する空気清浄器の吹き出し部側に設置されるものであり、器に内装した紫外線（ＵＶ－Ｃ）を遮断し、器外に漏洩するのを防止することができる、コンパクトで、構造が簡単で、安価な、紫外線カットフィルターを提供することである。 The invention described in Patent Document 2 is installed on the blowout side of an air purifier that kills bacteria and viruses in the air by irradiating it with ultraviolet rays (UV-C) and discharges the purified air to the outside of the device. To provide a compact, simple-structured, inexpensive UV cut filter capable of blocking ultraviolet rays (UV-C) contained in a container and preventing leakage to the outside of the container. is.

この特許文献２に記載の発明は、比較的構造が簡単で、安価なものを提供するという限りでは本発明の課題と一致する。
しかしながら、その解決手段は、「箱体の両端開口部にメッシュ４がそれぞれ取り付けられたフィルターボックスの内部に、ソーダガラスなどで作られた、球状又は多面体状の複数個の玉が複数層、積層して充填する構造体であり」、主として、有害な紫外線（ＵＶ－Ｃ）を遮断して器外に漏洩することのないようにするという発明の課題を達成するものであるから、本発明とは、技術的原理（発明の課題及び構造）が著しく相違する。 The invention described in Patent Document 2 is consistent with the object of the present invention as far as it provides a relatively simple structure and low cost.
However, the solution is that "a plurality of spherical or polyhedral balls made of soda glass or the like are stacked in multiple layers inside a filter box with meshes 4 attached to the openings at both ends of the box. "It is a structure that fills with the are remarkably different in technical principle (subject and structure of the invention).

上記構成に於いて、前記一群の仕切板は、前記ダクトの一側壁部の内壁面に一端部が接続されていると共に、他端部が前記ダクトの他壁部の全部或いは一部が内壁面から離れることより、前記他端部と前記他壁部の内壁面との間に空気の通り道を形成する第１群の仕切板と、逆に前記ダクトの他壁部の内壁面に前記他端部が接続されていると共に、前記一端部の全部或いは一部が前記ダクトの一側壁部の内壁面から離れることより、前記一端部と前記一側壁部の内壁面との間に空気の通り道を形成する第２群の仕切板とから成ることを特徴とする。また、前記一群の仕切板は、前記ダクトの内壁面に隙間なく接続すると共に一端部に空気の通り道を形成する第１透孔（例えば一本の水平長孔、複数の透孔など）を有する第１群の仕切板と、同様に前記ダクトの内壁面に隙間なく接続すると共に、前記一端部とは反対側の他端部に空気の通り道を形成する第２透孔（例えば一本の水平長孔、複数の透孔など）を有する２群の仕切板とから成ることを特徴とする。また、前記第１群の仕切板と第２群の仕切板は、前記一端開口部から他端開口部に向けて交互に配設され、少なくとも前記第１群の仕切板と前記第２群の仕切板の間には、合計４個を含む蛍光灯型の紫外線照射手段又は紫外線ＬＥＤのいずれか一方が配設されていることを特徴とする。 In the above configuration, the group of partition plates has one end connected to the inner wall surface of one side wall of the duct, and the other end connected to the inner wall surface of the other wall of the duct in whole or in part. the first group of partition plates forming an air passage between the other end portion and the inner wall surface of the other wall portion, and conversely, the other end portion is attached to the inner wall surface of the other wall portion of the duct are connected, and all or part of the one end is separated from the inner wall surface of the one side wall of the duct, thereby forming an air passage between the one end and the inner wall surface of the one side wall. and a second group of partition plates to be formed. In addition, the group of partition plates is connected to the inner wall surface of the duct without gaps and has a first through hole (for example, one horizontal long hole, a plurality of through holes, etc.) forming an air passage at one end. A second through hole (e.g., one horizontal and two groups of partition plates having long holes, a plurality of through holes, etc.). Further, the first group of partition plates and the second group of partition plates are alternately arranged from the one end opening toward the other end opening, and at least the first group of partition plates and the second group of partition plates are arranged alternately. Between the partition plates, either one of four fluorescent lamp type ultraviolet irradiation means or ultraviolet LEDs is arranged.

また、前記ダクトの開口部から見える仕切板に、前記空気の通り道を狭め、よって、該ダクト内の空気の流速を制御することができる可動式の制御部材を設けたことを特徴とする。さらに、前記一群の仕切板の壁面又は前記ダクトの内壁面のいずれかに、鏡面仕上げ部分又は紫外線反射体のいずれか一方が設けられていることを特徴とする。加えて、殺菌された空気が流れる方のダクトの開口部側に殺菌状態検知手段を設け、この殺菌状態検知手段の検出情報は、情報処理装置に送信され、かつ、該情報処理装置で処理された殺菌状態は、該情報処理装置に接続する表示部に可視的に表示されることを特徴とする。 Also, the partition plate visible from the opening of the duct is provided with a movable control member that narrows the passage of the air, thereby controlling the flow velocity of the air in the duct.

さて、第１実施形態の空気殺菌装置Ｘは、建物の室内の内部空間に配備され、箱体の一例であるダクトの一端開口部４から他端開口部６へと大気圧等によって自然に流れる空気を多数の紫外線照射手段２によって殺菌するもので、例えば玄関扉を備えた建物の内部空間を構成する室内用換気扇、空気吹き出し手段、空気誘導手段等を備えた壁面に沿って水平状態、又は垂直状態、或いは又斜めの状態に取付けられる。ここで建物の内部空間は建物の出入り口に開閉扉が存在する場合は、共用部分の各住戸の玄関扉の外壁面に至る共用空間のみならず、各住戸の玄関扉の内壁面以降の専有部分の空間も含まれる。また建物には、住居のみならず、工場、作業所、仕事場、学校、病院、会議室、集会所、運動場、水族館などが含まれる。 Now, the air sterilizer X of the first embodiment is arranged in the interior space of the room of the building, and naturally flows from one end opening 4 to the other end opening 6 of a duct, which is an example of a box, by atmospheric pressure etc. Air is sterilized by a large number of ultraviolet irradiation means 2, for example, a horizontal state along a wall surface equipped with an indoor ventilation fan, air blowing means, air guiding means, etc. that constitutes the interior space of a building equipped with an entrance door, or It can be mounted vertically or diagonally. Here, the internal space of the building is not only the shared space extending to the outer wall surface of the entrance door of each dwelling unit in the common area, but also the exclusive area after the inner wall surface of the entrance door of each dwelling unit when there is an opening and closing door at the entrance of the building. space is also included. Buildings include not only residences but also factories, workshops, workplaces, schools, hospitals, conference rooms, assembly halls, playgrounds, aquariums, and the like.

この空気殺菌装置Ｘの基本的構成は、一端開口部４及び他端開口部６を有する直管型又は曲管型のダクト１と、該ダクトの内壁面と略直交するように、かつ、前記一端開口部４から他端開口部６に向かって所要間隔を有して併設されると共に、該ダクト内部を流れる空気を蛇行状に案内する一群の仕切板１１と、前記空気を殺菌することができるように前記一群の仕切板の間の全部又は一部に配設されたた多数の紫外線照射手段２とから成り、例えば発明の二次的な課題を達成する場合には、後述の第２実施形態で説図するように、可動式の制御部材を加味しても良い。 The basic configuration of this air sterilizer X consists of a straight or curved duct 1 having an opening 4 at one end and an opening 6 at the other end; A group of partition plates 11 arranged side by side from one end opening 4 toward the other end opening 6 with a required interval and guiding the air flowing inside the duct in a meandering manner, and the air can be sterilized. It consists of a large number of ultraviolet irradiation means 2 arranged in all or part between the group of partition plates as much as possible, and for example, in the case of achieving a secondary object of the invention, a second embodiment described later A movable control member may be included, as will be explained in .

そこで、まず第１実施形態の基本的構成について説明する。例えば直管型のダクト１は、図３の分解斜視図を参照にすると、両端開口の箱体本体１ａと、その下面に長手方向に所定間隔を有して多数の蛍光灯型の紫外線照射手段２が併設された長板状の上壁１ｂと、この上壁１ｂと略同一形状・同一の大きさであり、該上壁と対向する長板状の下壁１ｃとから成る。 Therefore, first, the basic configuration of the first embodiment will be described. For example, referring to the exploded perspective view of FIG. 3, the straight tube type duct 1 has a box main body 1a with openings at both ends, and a large number of fluorescent lamp type ultraviolet irradiating means provided on the lower surface thereof at predetermined intervals in the longitudinal direction. 2 and a long plate-like lower wall 1c which has substantially the same shape and size as the upper wall 1b and faces the upper wall.

実施形態では、前記長板状の下壁１ｃの上面（箱体本体と結合すると内面）に、長手方向に所定間隔を有して多数の蛍光灯型の紫外線照射手段２が設けられている。 In this embodiment, a large number of fluorescent lamp type ultraviolet irradiation means 2 are provided at predetermined intervals in the longitudinal direction on the upper surface of the long plate-shaped lower wall 1c (the inner surface when combined with the box main body).

紫外線照射手段２は、長板状の上壁１ｂの下面又は長板状の下壁１ｃの上面のいずれか一方に設けても良いが、好ましい実施形態では、長板状の上壁１ｂの下面及び長板状の下壁１ｃの上面に互いに水平方向に位置がずれるように合計４本以上設けるのが望ましい。 The ultraviolet irradiation means 2 may be provided on either the lower surface of the long plate-shaped upper wall 1b or the upper surface of the long plate-shaped lower wall 1c. And it is desirable to provide a total of four or more on the upper surface of the long plate-like lower wall 1c so that the positions thereof are shifted in the horizontal direction.

しかして、図３を基準にすると、前記箱体本体１ａは、図面左側に見える前壁３に、空気Ａ用の矩形或いは方形状の入口４が形成され、その反対側である図面右側の後壁５に、同様に空気Ａ用の矩形或いは方形状の出口６が形成されている。付言すると、前記入口４は直管型のダクト１の一端開口部に相当し、一方、前記出口６はダクト１の他端開口部に相当する。 Referring to FIG. 3, the box main body 1a has a rectangular or square inlet 4 for air A formed in a front wall 3 seen on the left side of the drawing, and a rear wall on the opposite side of the front wall 3 on the right side of the drawing. A rectangular or square outlet 6 for the air A is likewise formed in the wall 5 . In addition, the inlet 4 corresponds to one end opening of the straight pipe type duct 1 , while the outlet 6 corresponds to the other end opening of the duct 1 .

また、箱体本体１ａの入口４から見た右側壁７には、その上縁から下端部寄りの部位のまで筋状の垂直切欠部７ａと、その下縁から上端部寄りの部位まで筋状の垂直切欠部７ｂとが、前記入口４側から出口６側まで交互に所定間隔を有して多数形成されている。
一方、前記右側壁７と対向する左側壁８にも、長手方向に多少位置をずらして、その上縁から下端部寄りの部位のまで筋状の垂直切欠部８ａと、その下縁から上端部寄りの部位まで筋状の垂直切欠部８ｂとを多数形成している。なお、ここでは右側壁７の垂直切欠部７ａ、７ｂと左側壁８の垂直切欠部８ａ、８ｂをまとめて「垂直切欠部」という。 The right side wall 7 seen from the entrance 4 of the box body 1a has a vertical notch 7a extending from the upper edge to the lower end, and a linear notch 7a extending from the lower edge to the upper end. A large number of vertical notches 7b are alternately formed at predetermined intervals from the inlet 4 side to the outlet 6 side.
On the other hand, on the left side wall 8 opposite to the right side wall 7, the position is slightly shifted in the longitudinal direction, and a streak-like vertical notch 8a is formed from the upper edge to the lower end, and the lower edge to the upper end. A large number of streak-like vertical cutouts 8b are formed up to the side portion. Here, the vertical cutouts 7a, 7b of the right side wall 7 and the vertical cutouts 8a, 8b of the left side wall 8 are collectively referred to as "vertical cutouts".

ここで図２を参照にすると、一群の仕切板１１は、前記ダクト１の一側壁部（上壁）１ｂの内壁面に一端部が接続されていると共に、他端部が前記ダクトの他壁部（下壁）１ｃの全部或いは一部（端部の一部に切欠がある場合）が内壁面から離れることより、前記他端部と前記他壁部の内壁面との間に空気の通り道ａを形成する第１群の仕切板１１ａと、逆に前記ダクトの他壁部（下壁）１ｃの内壁面に前記他端部が接続されていると共に、前記一端部の全部或いは一部（端部の一部に切欠がある場合）が前記ダクトの一側壁部（上壁）１ｂの内壁面から離れることより、前記一端部と前記一側壁部の内壁面との間に空気の通り道ｂを形成する第２群の仕切板１１ｂとから成る。 Here, referring to FIG. 2, a group of partition plates 11 has one end connected to the inner wall surface of one side wall (upper wall) 1b of the duct 1 and the other end connected to the other wall of the duct. By separating all or part of the portion (lower wall) 1c (if there is a notch in a part of the end portion) from the inner wall surface, an air path is formed between the other end portion and the inner wall surface of the other wall portion. The other end is connected to the inner wall surface of the first group of partition plates 11a forming the duct a and the other wall (lower wall) 1c of the duct, and all or part of the one end ( When the end part has a notch) is separated from the inner wall surface of the one side wall (upper wall) 1b of the duct, an air path b between the one end and the inner wall surface of the one side wall and a second group of partition plates 11b forming

そして、前記下方に位置する空気の通り道ａと前記上方に位置する空気の通り道ｂは、各上下の位置を水平方向に順番に繰り返している。なお、ここで、第１群の仕切板１１ａと第２群の仕切板１１ｂをまとめて「一群の仕切板１１」という。 The lower air path a and the upper air path b repeat their vertical positions in order in the horizontal direction. Here, the first group of partition plates 11a and the second group of partition plates 11b are collectively referred to as "a group of partition plates 11".

したがって、前記上下の空気の通り道（ａ、ｂ）を含め、箱体１の入口４から入り込んだ室内の空気Ａは、望ましくは第１群の仕切板１１ａと第２群の仕切板１１ｂの間に位置する多数の紫外線照射手段２にそれぞれ照射されながら、例えば図６で示すように、所要時間をかけて蛇行状に出口６側へと大気圧等によって流れて行く。なお、ここで「所要時間」の一例として「３０秒以上」と記載したが、例えば新型コロナウイルスの不活化効果は、紫外線の波長と空気の紫外線の照射滞留時間との関係で決定することができるので、新型コロナウイルスの不活化の条件は、空気殺菌装置Ｘの基本的構成を考慮し、箱体の形状・大きさ・長さ、仕切板の枚数・厚さ・材質、仕切板の表面と裏面に対するめっきによる金属被膜（例えば鍍金膜、鍍銀膜など）、空気の滞留時間、処理風量を確保するための紫外線照射手段の種類・数・特性・配置態様等に関しては、当業者が試行錯誤により知見し得る事項であり、例えば箱体は長箱状とし、また仕切板は５枚以上～３０枚以内とし、紫外線照射手段２が紫外線ランプである場合には、４本以上～２９本以内として実験をすべきである。 Therefore, the indoor air A entering from the inlet 4 of the box 1, including the upper and lower air passages (a, b), desirably flows between the first group of partition plates 11a and the second group of partition plates 11b. While being irradiated by a large number of ultraviolet ray irradiation means 2 positioned at , for example, as shown in FIG. In addition, although "30 seconds or more" is described as an example of "required time" here, for example, the inactivation effect of the new coronavirus can be determined by the relationship between the wavelength of ultraviolet rays and the irradiation residence time of ultraviolet rays in the air. Considering the basic configuration of the air sterilizer X, the conditions for inactivating the new coronavirus are the shape, size, and length of the box, the number, thickness, and material of the partition plates, and the surface of the partition plates. The type, number, characteristics, arrangement, etc. of the ultraviolet irradiation means for securing the air retention time, air volume, etc., by plating on the back surface (e.g., plating film, plating silver film, etc.) It is a matter that can be found by mistake, for example, the box is long box-shaped, the number of partition plates is 5 to 30, and if the ultraviolet irradiation means 2 is an ultraviolet lamp, 4 to 29. Experiments should be done within

なお、本発明は、仕切板の多数の概念を４本以上～２９本以内に限定するものではなく、例えば図１で示した紫外線照射空気殺菌装置Ｘを複数個連結することも可能であるから、そのような実施形態の場合には、全体として仕切板及び紫外線照射手段２が増える。 In addition, the present invention does not limit the concept of a large number of partition plates to 4 or more and 29 or less, and for example, it is possible to connect a plurality of ultraviolet irradiation air sterilizers X shown in FIG. In such an embodiment, the number of partition plates and ultraviolet irradiation means 2 is increased as a whole.

ところで、例えば図１を参照にすると、ダクト１内に入り込んだ空気Ａは、通り道ａと通り道ｂを順番に通過することから、上下方向に蛇行状にながれるが、仮に、図１を左右何れか一方に９０度回転した場合には、前記通り道ａと通り道ｂは、左右に位置することになるから、このような場合にはダクト１内に入り込んだ空気Ａは、左右に蛇行状に流れることになる。したがって、本発明は、空気Ａが左右に蛇行状に流れる実施形態を排除するものではない。 By the way, referring to FIG. 1, for example, the air A entering the duct 1 passes through the path a and the path b in order, so that it flows vertically in a meandering manner. When the duct 1 is rotated 90 degrees in one direction, the passage a and the passage b are located on the left and right sides. become. Therefore, the present invention does not exclude embodiments in which the air A flows in a meandering pattern from side to side.

また図５は、箱体１の内部に一群の仕切板１１を配置した場合の概略説明図であるが、実施形態では、複数の固着具、接着剤等の固定手段を利用し、箱体本体１ａに長板状の上壁１ｂと下壁１ｃとを固定し、両端開口のダクト１に製作した場合には、左右の側壁７、８の各垂直切欠部７ａ、７ｂ、８ａ、８ｂにそれぞれ第１群の仕切板１１ａと第２群の仕切板１１ｂを差し込み、これにより、例えば図２の状態にする。したがって、構成部材の紫外線照射２及び一群の仕切板１１を前記多数の垂直切欠部７ａ、７ｂ、８ａ、８ｂ介して両端開口のダクト１に容易に組み込むことができるという効果を得ることができる。 FIG. 5 is a schematic explanatory diagram of a case where a group of partition plates 11 are arranged inside the box 1. In the embodiment, fixing means such as a plurality of fasteners and adhesives are used to secure the box main body. When a long plate-like upper wall 1b and a lower wall 1c are fixed to 1a to manufacture a duct 1 with openings at both ends, vertical cutouts 7a, 7b, 8a, and 8b of left and right side walls 7 and 8 have vertical cutouts 7a, 7b, 8a, and 8b, respectively. The partition plate 11a of the first group and the partition plate 11b of the second group are inserted, thereby, for example, the state shown in FIG. Therefore, it is possible to obtain the effect that the ultraviolet irradiation 2 and the group of partition plates 11, which are the constituent members, can be easily incorporated into the duct 1 which is open at both ends through the many vertical notches 7a, 7b, 8a, and 8b.

この欄では、本発明の第２実施形態、３実施形態などを説明する。なお、これらの実施形態を説明するにあたって、第１実施形態と同一の部分については、同一又は同様の符号を付し、重複する説明を省略する。 In this column, the second embodiment, third embodiment, etc. of the present invention will be described. In describing these embodiments, the same or similar reference numerals will be given to the same parts as in the first embodiment, and redundant description will be omitted.

まず、図７乃至図９は本発明の第２実施形態を示す各説明図である。図７は、図５と同様の概略説明図であるから、箱体１は仮想線で示すと共に、紫外線照射手段２は省略する。図８は矩形状の仕切板１１Ａの一端部に水平長孔状の透孔（通り道ａ１と通り道ｂ１）を形成したことを示す。図９は図２と同様の概念図であるが、矩形状の仕切板１１Ａを逆様すると、前記一端部に水平長孔状の透孔（通り道ａ１と通り道ｂ１）は逆様になる。ここでは便宜上、仕切板１１Ａに下方に位置する水平長孔状を「第１透孔ａ１」とし、一方、仕切板１１Ａに上方に位置する水平長孔状を「第２透孔ｂ１」とする。
したがって、図９は図２と同様の概念図であるが、空気Ａが仕切板１１Ａに形成した下方の第１透孔ａ１と上方の第２透孔ｂ１を繰り返して通過することになる。 First, FIGS. 7 to 9 are explanatory diagrams showing the second embodiment of the present invention. Since FIG. 7 is a schematic illustration similar to FIG. 5, the box 1 is indicated by phantom lines and the ultraviolet irradiation means 2 is omitted. FIG. 8 shows that horizontally elongated through holes (passage a1 and passage b1) are formed at one end of a rectangular partition plate 11A. FIG. 9 is a conceptual diagram similar to FIG. 2, but when the rectangular partition plate 11A is turned upside down, the horizontal elongated through-holes (passage a1 and passage b1) at the one end are turned upside down. Here, for the sake of convenience, the horizontally elongated hole positioned below the partition plate 11A is referred to as "first through hole a1", while the horizontally elongated hole positioned above the partition plate 11A is referred to as "second through hole b1". .
Therefore, although FIG. 9 is a conceptual diagram similar to FIG. 2, the air A repeatedly passes through the lower first through hole a1 and the upper second through hole b1 formed in the partition plate 11A.

それ故に、第２実施形態の紫外線照射空気殺菌装置Ｘ１は、その一群の仕切板１１Ａは、ダクト１の内壁周面に隙間なく接続すると共に一端部に空気Ａの通り道を形成する第１透孔（例えば一本又は複数本の水平長孔、複数の透孔など）ａ１を有する第１群の仕切板１１ａと、同様に前記ダクト１の内壁周面に隙間なく接続すると共に、前記一端部とは反対側の他端部に空気の通り道を形成する第２透孔（例えば一本又は複数本の水平長孔、複数の透孔など）ｂ１を有する２群の仕切板１１ｂとから成ることを特徴とする。このように構成しても、第１実施形態と同一の作用・効果がある。 Therefore, in the ultraviolet irradiation air sterilizer X1 of the second embodiment, the group of partition plates 11A are connected to the inner wall peripheral surface of the duct 1 without gaps, and the first through holes that form the passage of the air A at one end. A first group of partition plates 11a having a1 (for example, one or a plurality of horizontal long holes, a plurality of through holes, etc.) are similarly connected to the inner wall peripheral surface of the duct 1 without gaps, and are connected to the one end portion. consists of two groups of partition plates 11b having second through holes (e.g., one or a plurality of horizontal long holes, a plurality of through holes, etc.) b1 that form air passages at the other end on the opposite side. Characterized by Even with this configuration, there are the same functions and effects as in the first embodiment.

次に図１０乃至図１２は本発明の第３実施形態を示す各説明図で、図１０は、例えば第１実施形態に対して、垂直案内部（例えば摩擦抵抗があるスリット、切欠部など）１４を介して上下方向にスライド可能な矩形状の制御板１５を入口４側の最初の仕切板の壁面１１ａに取付けた一例を示す説明図である。 Next, FIGS. 10 to 12 are explanatory diagrams showing a third embodiment of the present invention. FIG. 10 shows, for example, a vertical guide portion (for example, a slit with frictional resistance, a notch portion, etc.) for the first embodiment. 14 is an explanatory diagram showing an example in which a rectangular control plate 15 that can slide vertically via 14 is attached to the wall surface 11a of the first partition plate on the side of the entrance 4. FIG.

また図１１は、図１０に於いて、要部の概略断面説明図で、空気Ａの通り道ａが全開状態の姿勢を示す。一方、図１２は、図１０に於いて、同様に要部の概略断面説明図、空気Ａの通り道ａが、前記矩形状の制御板１５によって一部絞られた状態の姿勢を示す。なお、制御板１５で空気Ａの通り道ａを狭くした場合には、該制御板１５が自然落下しないように、ネジ、テープ等の固定手段を利用し、制御板１５を仕切板に適宜に固定する。
したがって、この第３実施形態は、第１実施形態の構成に於いて、ダクト１の一端開口（入口）４から見える仕切板１１ａに、前記空気Ａの最初の通り道ａを狭め、よって、該ダクト内１の空気Ａの流速を制御することができる可動式の制御部材１５を設けたことを特徴とする。なお、前記制御板１５の取付け場所に関しては、出口６側の最後の仕切板の壁面に取付けても良い。 FIG. 11 is a schematic cross-sectional explanatory view of the main part in FIG. 10, showing a posture in which the passage a of the air A is fully open. On the other hand, FIG. 12 is a schematic cross-sectional explanatory view of the essential parts of FIG. When the passage a of the air A is narrowed by the control plate 15, the control plate 15 is appropriately fixed to the partition plate by using a fixing means such as a screw or tape so that the control plate 15 does not fall naturally. do.
Therefore, in this third embodiment, in the configuration of the first embodiment, the first passage a of the air A is narrowed to the partition plate 11a visible from the opening (entrance) 4 at one end of the duct 1, so that the duct A movable control member 15 capable of controlling the flow velocity of the air A in the inner 1 is provided. As for the mounting location of the control plate 15, the control plate 15 may be mounted on the wall surface of the last partition plate on the exit 6 side.

次に図１３乃至図１５は本発明の第４実施形態を示す説明図である。特に図１４は要部であり、空気の通り道が全開状態の姿勢の説明図である。一方、図１５は、図１４に於いて、空気の通り道が一部絞られた状態の姿勢を示す。この第４実施形態は、前記第２実施形態に対して、前記第３実施形態の上下方向にスライド可能な矩形状の制御板１５を、回転可能な円板状の摘み部を有する制御部材（例えば制御板）１５Ａに置換したものである。この場合、少なくとも入口４側の最初の仕切板の第１透孔ａ１は、水平長孔ではなく、周端部の一部に弧状切欠部１５ａを有する円板状の制御板１５Ａの形状に対応させて「上向き弧状」に形成するのが望ましい。このように構成しても、第３実施形態と同様に、該ダクト内１の空気Ａの流速を制御することができる。 13 to 15 are explanatory diagrams showing a fourth embodiment of the present invention. In particular, FIG. 14 is a main part, and is an explanatory diagram of a posture in which the air passage is fully open. On the other hand, FIG. 15 shows the posture of FIG. 14 in which the air passage is partially constricted. In contrast to the second embodiment, the fourth embodiment replaces the vertically slidable rectangular control plate 15 of the third embodiment with a rotatable disk-shaped control member ( For example, it is replaced with a control plate) 15A. In this case, at least the first through hole a1 of the first partition plate on the side of the inlet 4 corresponds to the shape of a disk-shaped control plate 15A having an arc-shaped notch 15a at a part of the peripheral edge instead of a horizontal long hole. It is desirable to form an "upward arc" by Even with this configuration, the flow velocity of the air A in the duct 1 can be controlled as in the third embodiment.

次に図１６は本発明の第５実施形態を示す説明図である。第５実施形態は、一群の仕切板１１の壁面又はダクト１の内壁面のいずれかに、鏡面仕上げ部分又は紫外線反射体１６のいずれか一方が設けられていることを特徴とする。この第５実施形態では、紫外線ランプ２が取り付けられた内壁面の反対側に相当する内壁面に帯状の紫外線反射体１６を貼着している。なお、ダクト１の内壁面の全体を鏡面仕上げ部分にしても良い。 Next, FIG. 16 is an explanatory diagram showing a fifth embodiment of the present invention. The fifth embodiment is characterized in that either the wall surface of the group of partition plates 11 or the inner wall surface of the duct 1 is provided with either a mirror-finished portion or an ultraviolet reflector 16 . In this fifth embodiment, a strip-shaped ultraviolet reflector 16 is attached to the inner wall surface opposite to the inner wall surface on which the ultraviolet lamps 2 are attached. Note that the entire inner wall surface of the duct 1 may be mirror-finished.

最後に図１７は本発明の第６実施形態を示す説明図である。今や新型コロナウイルス感染症（ＣＯＶＩＤ－１９）やインフルエンザ等の感染症を予防するために、手洗いや消毒は欠かすことができない。 Finally, FIG. 17 is an explanatory diagram showing a sixth embodiment of the present invention. Hand washing and disinfection are now indispensable to prevent infectious diseases such as the new coronavirus infection (COVID-19) and influenza.

現在、世界中の人々は、新型コロナウイルス感染症（ＣＯＶＩＤ－１９）のワクチンが全世界の人々が満足するような状態になるに至るまでの間は、毎日、新型コロナウイルス感染症（ＣＯＶＩＤ－１９）に感染するリスクと共に日常生活をおくらなければならない。 People all over the world are now ready to fight COVID-19 every day until a vaccine for COVID-19 is in place to the satisfaction of the whole world. 19) must live with the risk of infection.

ところで、新型コロナウイルス感染症対策の一つとして、日本国の厚生労働省（新型コロナウイルス感染症対策テックチーム等）は、新型コロナウイルス感染症（ＣＯＶＩＤ－１９）拡大防止策の１つとして「新型コロナウイルス接触確認アプリ（以下、本明細書では、「殺菌状態検知手段（検知アプリ）」という。）」の仕様書を２０２０年５月２６日に公表し、殺菌状態検知手段（検知アプリ）を２０２０年６月１９日にリリースした。
したがって、殺菌状態検知手の一例として、室内設置の端末が殺菌状態検知手段をインストールした場合には、情報処理装置、通信網及び測定情報管理サーバ等のシステムにより、前記殺菌状態検知手段を有する紫外線照射空気殺菌装置から、新型コロナウイルスが室内に持ち込まれたか否かを監視することができる。 By the way, as one of the measures against the new coronavirus infectious disease, the Ministry of Health, Labor and Welfare of Japan (new coronavirus infectious disease control tech team, etc.) has announced that one of the measures to prevent the spread of the new coronavirus infectious disease (COVID-19) The specification of the coronavirus contact confirmation application (hereinafter referred to as "sterilization state detection means (detection application)" in this specification)" was published on May 26, 2020, and the sterilization state detection means (detection application) was Released on June 19, 2020.
Therefore, as an example of a sterilization state detection method, when a terminal installed indoors has a sterilization state detection means installed, a system such as an information processing device, a communication network, and a measurement information management server can detect ultraviolet rays having the sterilization state detection means. From the irradiation air sterilizer, it is possible to monitor whether the new coronavirus is brought into the room.

そこで、第６実施形態は、例えば殺菌された空気が流れる方のダクト１の開口部６側に短筒状部１７を連設し、この短筒状部１７にアーム１８を介して殺菌状態検知手段１９を格納する端末を取り外し可能に設け、この殺菌状態検知手段の検出情報（例えば新型コロナウイルスが存在する情報）は、情報処理装置３０に有線又は無線で送信され、かつ、該情報処理装置３０で処理された殺菌状態に関するデータは、該情報処理装置に接続する該情報処理装置の表示部３６又は測定情報管理サーバ３８の表示部３９のいずれか一方に可視的に表示されることを特徴とする紫外線照射空気殺菌装置Ｘ２である。 Therefore, in the sixth embodiment, for example, a short cylindrical portion 17 is continuously provided on the side of the opening 6 of the duct 1 through which sterilized air flows, and an arm 18 is attached to the short cylindrical portion 17 to detect the sterilization state. A terminal that stores means 19 is detachably provided, and detection information of this sterilization state detection means (for example, information that the new coronavirus is present) is transmitted to an information processing device 30 by wire or wirelessly, and the information processing device The data on the sterilization state processed in 30 is visibly displayed on either the display unit 36 of the information processing device connected to the information processing device or the display unit 39 of the measurement information management server 38. It is an ultraviolet irradiation air sterilizer X2.

なお、殺菌状態検知手段（検知アプリ）は、ダクト１の内部を流れる空気が、少なくとも３０秒以上乃至６０秒以下の滞留時間帯の中で、新型コロナウイルスを構成する特定のウイルス組成物（ｓｍａｌｌ ｌｉｖｉｎｇ ｔｈｉｎｇｓ）を検出する機能を有するものとする。 In addition, the sterilization state detection means (detection application) detects that the air flowing inside the duct 1 contains a specific virus composition (small living things).
