しかし殺菌装置の構造あるいは殺菌装置の取り付け位置や取り付け角度によると、紫外放射が装置の外部に漏れて、人間が紫外放射を視認する恐れがある。紫外放射を人間が視認すると有害であり改良が必要となる。   However, depending on the structure of the sterilizer or the attachment position and angle of the sterilizer, the ultraviolet radiation leaks to the outside of the device, and there is a risk that humans will see the ultraviolet radiation. Ultraviolet radiation is harmful to human eyes and needs to be improved.

本発明は上記の事情に鑑みてなされたもので、比較的簡易な構造で人間が紫外放射を視認する恐れがなく、さらに殺菌効果の優れた殺菌装置を提供することを目的とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sterilization apparatus that has a relatively simple structure and does not allow humans to visually recognize ultraviolet radiation, and has an excellent sterilization effect.

本発明は上記の課題を解決するために次の構成とする。請求項１は、中空筒体の装置本体の内部に紫外放射光源を装着し、同装置本体の一端近傍に空気ファンを配置して構成してある。また装置本体の他端近傍に循環する空気の圧力損失が少なく、且つ循環する空気が紫外放射光源により近接しながら送風され、さらに紫外放射が装置本体の外部に漏れるのを防止する調整蓋を設けて構成してある。 The present invention has the following configuration in order to solve the above problems. According to the first aspect of the present invention, an ultraviolet radiation light source is mounted inside the hollow cylindrical device main body, and an air fan is disposed in the vicinity of one end of the device main body. In addition, there is an adjustment lid that prevents the pressure loss of the air circulating near the other end of the device body from being low, blows the circulating air close to the ultraviolet radiation light source, and prevents ultraviolet radiation from leaking outside the device body. Configured.

請求項２は、請求項１における調整蓋を、上蓋と中蓋と内蓋の３枚で構成し、且つ同上蓋と中蓋と内蓋は間隔を有して配置し、さらに中蓋は循環する空気が紫外放射光源により近接するように、外周近傍と中央付近に空孔を有して構成してある。 According to a second aspect of the present invention, the adjustment lid according to the first aspect comprises three pieces of an upper lid, an inner lid, and an inner lid, and the upper lid, the inner lid, and the inner lid are arranged with a space therebetween, and the inner lid is circulated. So that the air to be moved closer to the ultraviolet radiation source has holes near the outer periphery and near the center.

請求項３は、請求項２における上蓋と中蓋と内蓋は、循環する空気が乱流を起こすように、内蓋は外周近傍に空孔があり、中蓋は外周近傍と中央付近に空孔があり、上蓋は中央近傍に空孔を有して構成してある。また同上蓋と中蓋と内蓋に形成された各空孔は位置をずらして形成され、上蓋の外部に紫外放射が漏れないように構成してある。 In claim 3, the upper lid, the inner lid, and the inner lid in claim 2 have holes in the vicinity of the outer periphery so that the circulating air causes turbulent flow, and the inner lid is empty in the vicinity of the outer periphery and near the center. There is a hole, and the upper lid has a hole in the vicinity of the center. Further, the holes formed in the upper lid, the inner lid, and the inner lid are formed so as to be shifted in position so that ultraviolet radiation does not leak outside the upper lid.

上記した本発明によると、構造は比較的簡易であるにもかかわらず人間が紫外放射を視認する恐れがなく、循環する空気は紫外放射光源に、より近接するので殺菌効果に優れ、さらに通過する空気は損失が少なく処理効果が高い特別な効果がある。   According to the present invention described above, although the structure is relatively simple, there is no risk of human beings visually recognizing ultraviolet radiation, and since the circulating air is closer to the ultraviolet radiation source, it has an excellent sterilizing effect and passes further.

１０は図３に示すように、装置本体１の長手方向の構成壁の一部に開閉自在に設けた紫外放射光源を交換するための内側開閉板であって、装置本体１に蝶番で支持して構成してある。１１は内側開閉板１０を覆ってなる外側開閉板であって、支持腕１２を介して内側開閉板１０に固定してある。１３は図１に示すように、装置本体１の構成壁の一部に設けた紫外放射光源の点灯確認窓である。１４は内側開閉板１０の内側に設けた透明ガラス、１５は外側開閉板１１の内側に設けた透明ガラス、１６は紫外放射光源２を挟んで配置してなる透明ガラスである。これらの透明ガラスは、紫外放射を透過しないものを用いて構成してある。なお、同透明ガラスは、紫外放射を透過せず、紫外放射により劣化しないものであればプラスチックを用いて構成してもよい。   As shown in FIG. 3, reference numeral 10 denotes an inner opening / closing plate for exchanging an ultraviolet radiation light source that can be freely opened and closed on a part of the structural wall in the longitudinal direction of the apparatus body 1 and is supported on the apparatus body 1 with a hinge. Configured. Reference numeral 11 denotes an outer opening / closing plate that covers the inner opening / closing plate 10, and is fixed to the inner opening / closing plate 10 via a support arm 12. As shown in FIG. 1, 13 is a lighting confirmation window for an ultraviolet radiation light source provided on a part of the constituent wall of the apparatus main body 1. 14 is a transparent glass provided inside the inner opening / closing plate 10, 15 is a transparent glass provided inside the outer opening / closing plate 11, and 16 is a transparent glass formed with the ultraviolet radiation light source 2 interposed therebetween. These transparent glasses are made of a material that does not transmit ultraviolet radiation. The transparent glass may be made of plastic as long as it does not transmit ultraviolet radiation and does not deteriorate by ultraviolet radiation.

２１は図１における下方のソケット４の下側に設けてなる空気ファンである。同空気ファン２１は、１ｍ3／ｍｉｎの送風量のものを用いて構成してある。２２は装置本体１の内底部に設けた点灯装置であって、紫外放射光源を点灯するための安定器等を有して構成してある。 An air fan 21 is provided below the lower socket 4 in FIG.

It will be. When the voids of the upper lid 32, the inner lid 33, and the inner lid 34 are substantially equal, the pressure loss can be minimized. In addition, the holes formed in the upper lid 32, the inner lid 33, and the inner lid 34 are shifted in position so that ultraviolet radiation does not leak outside the upper lid. When the upper lid 32, the inner lid 33, and the inner lid 34 are configured as described above, ultraviolet radiation does not leak to the outside regardless of the position and angle of attachment of the sterilizer, and the occupants visually recognize the ultraviolet radiation. You can prevent the risk of doing.
