【発明が解決しようとする課題】
前記従来技術においては、吸込口から空気を吸入させ発光体カバーと接触させてから吹出口から再び室内へ戻すというように空気の流れは一方向性のものであった。このような空気の流れが一方向性のものにおいては、空気と光触媒作用を有する物質との接触が限られたものとなり、空気浄化能力を高めることはできない。このため能力を高めるには、有害物質と酸化チタン等光触媒作用を有する物質を含む発光体カバー等の面積を大きくすること等が考えられるが、このような場合には、装置が大型化するなどの問題がある。
【０００５】
そこで、本発明は、空気中の有害物質と酸化チタン等光触媒作用を有する物質との接触面積を大きくすることができると共に、装置の小型化を図れる空気浄化装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
請求項１の発明は、一端に空気の入口を設けると共に他端に空気の出口を設けた空気通路の途中に発光体と、前記発光体の下流側に設けられた光触媒部材と、前記光触媒部材の下流側に設けられ該光触媒部材に臨む光と空気の反射板とを備えた空気清浄機であって、
前記入口と前記光触媒部材との間に前記発光体を設け、
前記光触媒部材は、板状であって、発光体の光と空気とが通り抜けるための通気孔を形成し、
前記出口と該光触媒部材との間には、前記光触媒部材の通気孔を通り抜けた光と空気とを前記光触媒部材へと反射させるための反射板を設けると共に、
前記反射板の周辺部には、前記光触媒部材と前記出口を連通する連通路を設けたことを特徴とする空気浄化装置である。
【０００７】
この請求項１の構成によれば、空気は入口より空気通路に沿って発光体、光触媒部材、反射板を通って出口より出る。この際、発光体の光は反射板によって反射される共に、空気は反射板によって反射されて、光触媒部材を通過した空気は再び光触媒部材と接触することができる。
【０００８】
また、この構成によれば、反射板によって光と空気が反射されて、光触媒部材の下流側においても空気の浄化を行うことができる。
【０００９】
さらに、この構成によれば、空気は入口より空気通路に沿って発光体、光触媒部材の通気孔、反射板の連通路を通って出口より出る。
【００１０】
【発明の実施形態】
以下、本発明の一実施形態を添付図を参照して説明する。箱型状ケース１は上面２、側面３及び底面４を有しており、内部は空洞状の浄化室５の一側に区画壁６を介して仕切り室７が形成されており、仕切り室７の上面２に空気の吸込口たる入口８を設けると共に、浄化室５の側面３の下部に空気の吹出口たる出口９を設ける。そして、ケース１内に入口８から出口９に至る空気通路１０が形成される。前記入口８の下方にファン型の吸引装置１１の１次側１２が接続しており、吸引装置１１の２次側１３は区画壁６の上部に横向きに開口して浄化室５に臨んでいる。尚、図中１４は入口８に設けた塵芥等を取り除くフィルター、１５はそのカバー、１６は仕切り室内に設けた電気制御装置である。
【００１１】
前記浄化室５の少なくとも上半分は空洞部１７となって、２次側１３から押し出され大気圧よりやや高圧な空洞部１７内の空気圧Ｐ１は、２次側１３における空気の空気圧Ｐ２よりも減少している（Ｐ１＜Ｐ２）。そして、浄化室５における上下方向の中間のやや下方に左右一対の紫外線ランプ等の紫外線の発光体１８を電極ホルダー１９を介して横向きに設ける。さらにこの発光体１８の下方、すなわち前記発光体１８の下流側に、酸化チタン等の光触媒作用を有する光触媒部材２０を横向きに設ける。光を放つ紫外線ランプは光触媒作用の利用目的に応じて、熱陰極型、冷陰極型或いは低温特性に優れたキセノン型といずれのタイプを使用してもよく、取扱い上の安全性から波長が３００ｎｍ以上の紫外線を使用することが好ましい。光触媒部材２０は、金網のように通気孔２１を複数形成した金属板に小さい孔を多数形成した板状本体２２に光触媒部たる酸化チタン２３等をバインダー２４を用いて保持させたものであり、表面に酸化チタン２３が表れて空気と接触できるようになっている。尚、この光触媒部材２０の周縁部２５は浄化室５の内壁に近接するか、接するようになっている。さらに、光触媒部材２０の下方、すなわち前記光触媒部材２０の下流側に反射板２６を前記光触媒部材２０と対峙するように設ける。この反射板２６の上流側の表面は鏡面又はほぼ鏡面或いは光沢を有するものであって、通気孔２１を通り抜けた空気を反射して再び前記光触媒部材２０に反射しており返す空気反射作用と、通気孔２１を通り抜けた紫外線を反射して光触媒部材２０の下面を照射する光反射作用をなすものであり、空気を反射するために反射板２６の上面のほぼ全面は平板状であって、特に前記発光体１８に対向する部位には孔等が形成されず、空気と光の反射を行うことができるようになっている。また紫外線を反射するために反射板２６の上面は鏡面状或いはほぼ鏡面状に形成されている。この反射板２６の両側は下方へ折曲してケース１の底面４に接する支持脚２７を形成して、反射板２６，２７と底面４との間に空間を形成するように反射板２６は底面４よりやや上方に配置している。また、反射板２６の四隅に支持柱２８を形成して、この支持柱２８により光触媒部材２０を間隔をおいてほぼ横向きに保持している。さらに、この反射板２６の周縁部２９は浄化室５の内壁に接するか、近接するようになっており、その周縁部２９のやや内側に該周縁部２９に沿って上下を連通する連通孔によって連通路３０が形成されている。尚、この連通路３０は支持柱２８よりも外側に配置されている。そして、ケース１の側面３の下部に前記出口９を設ける。この出口９の上流側は反射板２６と底面４との間に接続している。
【００１２】
次に前記構成についてその作用を説明する。予め吸引装置１１が作動していると共に、通電している発光体１８は発光して紫外線を出して、光触媒部材２０の上面における酸化チタン２３の表面に酸化分解作用をなしていると共に、発光体１８の紫外線の一部は通気孔２１を通り抜けて反射板２６に至り、そして反射板２６で反射された紫外線は光触媒部材２０の下面を照射することにより、光触媒部材２０の下面における酸化チタン２３の表面に酸化分解作用をなすようになっている。そしてフィルター１４により塵芥等を取り除かれた外気は入口８より吸引されて２次側１３より空洞部１７に他側側面３の内壁に向かって排出される。そして、空気は空気通路１０に沿うように浄化室５を通って大気状態の出口９より大気に放出される。このように浄化室５を通過するとき、空洞部１７において空気は他側の側面３に衝突したり、或いは大気圧よりやや高い空気圧となっている空洞部１７において空気は乱流状態となる。このように空洞部１７において乱流状態となった空気は発光体１８、光触媒部材２０の通気孔２１を通過し、紫外線が照射され紫外線により酸化チタン２３の表面に発生する強い酸化分解力により、空気中の有害物質等を分解する。酸化チタン２３に触れずに通気孔２１を通過した空気は、反射板２６の上面に衝突して光触媒部材２０と反射板２６との間に滞留すると共に、その一部は滞留中に光触媒部材２０の酸化チタン２４に接することにより、光触媒部材２０の下面側においても空気中の有害物質等を分解する。そして、光触媒部材２０と反射板２６との間に滞留する空気の一部は、連通路３０を通って底面４上の出口９より有害物質等を分解した浄化された空気が排出されるものである。
【００１３】
以上のように、前記実施形態では空気通路１０の途中に発光体１８と、該発光体１８の下流側に設けられた酸化チタン２３を有する光触媒部材２０と、光触媒部材２０の下流側に該光触媒部材２０に臨む光反射と空気反射をなす反射板２６とを備え、光触媒部材２０を通過した紫外線を反射板２６の光反射作用により光触媒部材２０の下面（下流側）に照射すると共に、光触媒部材２０を通過した空気を反射板２６による空気反射作用により光触媒部材の下面（下流側）に逆流することにより、光触媒部材２０をいったん通過した空気を再び光触媒部材２０の下面側で浄化することができるので、空気と紫外線が照射された酸化チタンとの接触面積を大きくでき、空気浄化の効率を向上することができる。
【００１４】
また、光の反射と空気の反射を上流側の表面を鏡面又はほぼ鏡面とした反射板２６により一体に形成したことにより、反射板２６によって光と空気が反射されて装置を小型化できる。
【００１５】
さらに、前記入口８と前記発光体１８との間に空洞部１７を設けると共に、前記入口８側に吸引装置１１を設け、前記光触媒部材２０は通気孔２１を形成した板状であって、該光触媒部材２１に対峙するように前記反射板２６を設けると共に、該反射板２６の周辺部２９に前記光触媒部材２０側と前記出口９側を連通する連通路３０を設けたことにより、空洞部１７内が加圧されて空気は空洞部で乱流状態となり、そして反射板２６によって反射された空気の逆流を阻害しにくくなり、反射した空気を再び光触媒部材２０と接触しやすくなる。
【００１６】
しかも、入口８からの空気は間隔をおいて重ね合わせるように配置した発光体１８と光触媒部材２０と反射板２６とを通過して浄化され、空気通路１０の全体の流れは途中で乱流状態などがあったにしても全体としては迂回などすることなく直流的となって損失を可及的に少なくすることができる。
【００１７】
尚、本発明は上記実施形態に限定されるものではなく、本発明の要旨の範囲内において、種々の変形実施が可能である。
【００１８】

[0004]
[Problems to be solved by the invention]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The box-shaped case 1 has an upper surface 2, a side surface 3, and a bottom surface 4. A partition chamber 7 is formed on one side of a hollow purification chamber 5 via a partition wall 6. An inlet 8 that is an air suction port is provided on the upper surface 2, and an outlet 9 that is an air outlet is provided at the lower portion of the side surface 3 of the purification chamber 5. An air passage 10 extending from the inlet 8 to the outlet 9 is formed in the case 1. The primary side 12 of the fan-type suction device 11 is connected to the lower side of the inlet 8, and the secondary side 13 of the suction device 11 opens laterally above the partition wall 6 and faces the purification chamber 5. . In the figure, 14 is a filter for removing dust and the like provided at the inlet 8, 15 is a cover thereof, and 16 is an electric control device provided in the partition chamber.
[0011]
At least the upper half of the purification chamber 5 becomes a cavity portion 17, and the air pressure P <b> 1 in the cavity portion 17 that is pushed out from the secondary side 13 and is slightly higher than the atmospheric pressure is smaller than the air pressure P <b> 2 of the air on the secondary side 13. (P1 <P2). Then, an ultraviolet light emitter 18 such as a pair of left and right ultraviolet lamps is provided laterally through an electrode holder 19 slightly below the middle of the purification chamber 5 in the vertical direction. Further, a photocatalytic member 20 having a photocatalytic action such as titanium oxide is provided laterally below the light emitter 18, that is, downstream of the light emitter 18. Depending on the purpose of photocatalytic action, the UV lamp that emits light may use either a hot cathode type, a cold cathode type, or a xenon type with excellent low temperature characteristics, and has a wavelength of 300 nm for safety in handling. It is preferable to use the above ultraviolet rays. The photocatalyst member 20 is a plate-like body 22 in which a plurality of small holes are formed in a metal plate in which a plurality of vent holes 21 are formed like a metal mesh, and a titanium oxide 23 or the like as a photocatalyst portion is held using a binder 24, Titanium oxide 23 appears on the surface and can come into contact with air. The peripheral edge 25 of the photocatalytic member 20 is close to or in contact with the inner wall of the purification chamber 5. Further, a reflector 26 is provided below the photocatalyst member 20, that is, on the downstream side of the photocatalyst member 20 so as to face the photocatalyst member 20. The upstream surface of the reflecting plate 26 has a mirror surface or a substantially mirror surface or gloss, and reflects the air that has passed through the vent hole 21 and reflected back to the photocatalyst member 20; It reflects the ultraviolet light that has passed through the vent hole 21 and irradiates the lower surface of the photocatalyst member 20, and has a plate-like shape over the entire upper surface of the reflector 26 in order to reflect air. A hole or the like is not formed in a portion facing the light emitter 18 so that air and light can be reflected. In order to reflect ultraviolet rays, the upper surface of the reflection plate 26 is formed into a mirror surface or substantially a mirror surface. Both sides of the reflecting plate 26 are bent downward to form support legs 27 that contact the bottom surface 4 of the case 1, and the reflecting plate 26 is formed so as to form a space between the reflecting plates 26, 27 and the bottom surface 4. It is arranged slightly above the bottom surface 4. Further, support pillars 28 are formed at the four corners of the reflection plate 26, and the photocatalyst members 20 are held substantially horizontally by the support pillars 28 at intervals. Further, the peripheral edge portion 29 of the reflector 26 is in contact with or close to the inner wall of the purification chamber 5, and a communication hole that communicates vertically along the peripheral edge portion 29 slightly inside the peripheral edge portion 29. A communication path 30 is formed. The communication passage 30 is disposed outside the support column 28. The outlet 9 is provided at the lower part of the side surface 3 of the case 1. The upstream side of the outlet 9 is connected between the reflecting plate 26 and the bottom surface 4.
[0012]
Next, the operation of the above configuration will be described. While the suction device 11 is activated in advance, the energized illuminator 18 emits light and emits ultraviolet rays, and the surface of the titanium oxide 23 on the upper surface of the photocatalyst member 20 is oxidized and decomposed. A part of the ultraviolet light 18 passes through the vent hole 21 and reaches the reflection plate 26, and the ultraviolet light reflected by the reflection plate 26 irradiates the lower surface of the photocatalyst member 20, so that the titanium oxide 23 on the lower surface of the photocatalyst member 20 is irradiated. The surface has an oxidative decomposition effect. The outside air from which dust and the like have been removed by the filter 14 is sucked from the inlet 8 and discharged from the secondary side 13 to the hollow portion 17 toward the inner wall of the other side surface 3. Then, the air passes through the purification chamber 5 along the air passage 10 and is released to the atmosphere from the outlet 9 in the atmospheric state. Thus, when passing through the purification chamber 5, the air collides with the side surface 3 on the other side in the hollow portion 17, or the air is in a turbulent state in the hollow portion 17 where the air pressure is slightly higher than the atmospheric pressure. Thus, the air in the turbulent state in the hollow portion 17 passes through the light emitting body 18 and the vent hole 21 of the photocatalyst member 20, and is irradiated with ultraviolet rays, and due to the strong oxidative decomposition force generated on the surface of the titanium oxide 23 by the ultraviolet rays, Decomposes harmful substances in the air. The air that has passed through the vent hole 21 without touching the titanium oxide 23 collides with the upper surface of the reflection plate 26 and stays between the photocatalyst member 20 and the reflection plate 26, and a part of the air remains during the stay. By contacting the titanium oxide 24, harmful substances in the air are decomposed also on the lower surface side of the photocatalyst member 20. A part of the air staying between the photocatalyst member 20 and the reflection plate 26 passes through the communication path 30 and is discharged from the outlet 9 on the bottom surface 4 through purified air that decomposes harmful substances and the like. is there.
[0013]
As described above, in the above embodiment, the photocatalyst member 20 including the light emitter 18 in the middle of the air passage 10, the titanium oxide 23 provided on the downstream side of the light emitter 18, and the photocatalyst on the downstream side of the photocatalyst member 20. A reflection plate 26 that makes light reflection facing the member 20 and air reflection, and irradiates the lower surface (downstream side) of the photocatalyst member 20 with ultraviolet light that has passed through the photocatalyst member 20 by the light reflection action of the reflection plate 26, and also the photocatalyst member The air that has passed through the photocatalyst member 20 is allowed to flow back to the lower surface (downstream side) of the photocatalyst member due to the air reflection effect of the reflector 26 so that the air once passed through the photocatalyst member 20 can be purified again on the lower surface side of the photocatalyst member 20. Therefore, the contact area between air and titanium oxide irradiated with ultraviolet rays can be increased, and the efficiency of air purification can be improved.
[0014]
Further, since the reflection of light and the reflection of air are integrally formed by the reflection plate 26 whose upstream surface is a mirror surface or substantially a mirror surface, the light and air are reflected by the reflection plate 26, and the apparatus can be downsized.
[0015]
Further, a cavity 17 is provided between the inlet 8 and the light emitter 18, a suction device 11 is provided on the inlet 8 side, and the photocatalytic member 20 has a plate shape in which a vent hole 21 is formed, The reflection plate 26 is provided so as to face the photocatalyst member 21, and the communication portion 30 that connects the photocatalyst member 20 side and the outlet 9 side is provided in the peripheral portion 29 of the reflection plate 26, whereby the cavity portion 17. The inside is pressurized and the air becomes turbulent in the cavity, and the backflow of the air reflected by the reflecting plate 26 becomes difficult to be inhibited, and the reflected air easily comes into contact with the photocatalyst member 20 again.
[0016]
Moreover, the air from the inlet 8 is purified by passing through the light emitter 18, the photocatalyst member 20, and the reflector 26 arranged so as to overlap each other at intervals, and the entire flow of the air passage 10 is in a turbulent state on the way. Even if there is, there is no detour as a whole, and it becomes a direct current and the loss can be reduced as much as possible.
[0017]
In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention.
[0018]
