Description

【0001】
【発明の属する技術分野】
本発明は、空気清浄器に関するもので、空気の浄化、有害ガスの除去、構成部品、または本体全体の防汚やメンテナンスの向上に関するものである。
【0002】
【従来の技術】
従来、この種の空気清浄器は、例えば図5、図6に示すような構造になっていた。1は格子状の吸気口1aを本体前面に有するフロントグリル、2は中間部を成す本体前、3は後部を成し、裏側面に壁掛け金具4と下げ手部5を有する本体後、6は本体前2と本体後3との間に形成された渦室で、内部にはモーター7に連結されたファン8から成る送風装置を有している。本体前2の前面には吸い込み口9とリブ10が設けられており、リブ10はその前面に位置し、脱臭用の活性炭フィルター11aと集塵用の帯電フィルター11bより形成された集塵装置のフィルター11を支持している。
【0003】
吸い込み口9は、本体内のモーター7及びファン8と連通している。12は本体前2と本体後3に挟み込まれた格子状の排気口12aを有する排気口グリル、13は本体前2の前面上部に設けられた切り替えスイッチ部で、内部に制御回路部14を有し、運転操作は、切り替えスイッチ部13により操作することができる。上記フロントグリル1は、下部に形成した引っ掛け部15を本体前2の下方の突出部16に形成した嵌合穴17に挿入し、次に、上部左右の両側に設けた係部18と本体前2の取っ手部19の近くに設けた爪20とを係合させることにより着脱自在に取り付けている。
【0004】
上記構成において、動作を説明すると、切り替えスイッチ部13によりモーター7を回転させると、同モーター7に連結されたファン8が回転し、吸気口1aより空気が吸い込まれる。吸引された空気流は活性炭フィルター11aと帯電フィルター11bを合わせたフィルター11の集塵装置を通り、排気口12aへと排気されて空気が脱臭、浄化されていく。
【0005】
【発明が解決しようとする課題】
室内空気の汚れには、ほこりやたばこの煙、ウイルスを含む菌等の微生物、室外から入って来る自動車から排気された大気汚染物質(NOx,SOx等)を含んだ有害ガス成分、及びそれらに含まれる臭い成分等があるが、臭い成分については、脱臭用の活性炭フィルター11aで脱臭され、ほこり、煙等の粒子成分については、集塵用の帯電フィルター11bによって浄化される。しかし、大気汚染物質(NOx,SOx等)を含んだ有害ガス成分については、脱臭用の活性炭フィルターの活性炭に化学薬品を添加することで一部除去はしているものの極少量であり、ほとんど浄化されていないのが現状である。
【0006】
又、ウイルスを含む菌等の微生物についても大きい物は、集塵用の帯電フィルター11bによって捕獲されるが、極少量でありほとんど浄化されていない。そして殺菌という点では、集塵用の帯電フィルターに抗菌処理を施すことで一部不活化しているが殺菌迄には至っていないのが現状である。
【0007】
そして、たばこの煙やその他の汚れが吸気口や排気口の格子部や本体外壁に付着して汚れてしまい、布等による水拭きや乾拭き等では、容易に落ちないという問題も有していた。
【0008】
そこで、本発明は、ウイルスを含む菌等の微生物の殺菌と大気汚染物質(NOx,SOx等)を含んだ有害ガス成分の除去を向上させると共に本体の汚れ防止、すなわち防汚と、本体に付着した汚れを布等による水拭きや乾拭き等で容易に清掃メンテナンス出来るようにすることを第一の目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するために本発明は、モ―タ―ファンからなる電動送風装置、集塵装置を内蔵し、一部に吸排気口を有する本体外壁表面に光触媒処理を施し、前記吸排気口を構成する部材表面に光触媒処理を施し、前記本体を本体前、本体後で構成し、前記ファン表面に接触して流れる空気中の殺菌と有害ガス成分を除去するように前記ファンの表面に光触媒処理を施すと共に前記本体後を透明な材料で形成し、紫外線光を透過させ、空気中の亜硫酸ガスの有害ガス成分が光触媒により酸化されイオン化した酸化生成物に変えられ鉄系金属酸化物と結合して塩を生成し酸化生成物を捕捉することを特徴とし、そしてまた前記本体を構成する部材、前記吸排気口を構成する部材、及び前記ファンを形成する材料に光触媒処理材を練り込むことによって同光触媒処理を施すことにより、光触媒処理が施された面に紫外線を含む太陽光又は蛍光灯が照射されると光触媒が活性化されて、光触媒との接触反応によりウイルスを含む菌等の微生物を殺傷し、且つ有害ガス成分を酸化させて、光触媒処理を施した面に吸着させることにより有害ガス成分を除去するようにするものである。また、空気中の亜硫酸ガスの有害ガス成分が光触媒により酸化され、イオン化した酸化生成物に変えられ、鉄系金属酸化物と結合して塩を生成し、酸化生成物を捕捉する為、有害ガス成分の除去効果をより一層高めるものである。
【0010】
また、上記に示す光触媒との接触反応によって有害ガス成分が酸化されて出来た酸化生成物を光触媒処理を施した面に付着させることにより、たばこの煙やその他の汚れが光触媒処理を施した吸気口や排気口の格子部、本体外壁面に付着するのを防止し、また付着したとしても剥離しやすい酸化生成物に付着させることで、布等による水拭きや乾拭き等で容易に清掃メンテナンス出来るようにするものである。

【0017】
本発明の請求項記載の発明は、前記本体、前記吸排気口を構成する部材、前記ファンを形成する材料に光触媒処理材を練り込むことによって同光触媒処理を施すことにより、同様にして、本体の周囲に漂って本体外壁表面に接触している空気中や本体に吸排気される空気流中の殺菌と有害ガス成分を除去することが出来るものである。
【0018】
また、同様にして、たばこの煙やその他の汚れが光触媒処理を施した本体外壁面に付着するのを防止し、また付着したとしても剥離しやすい酸化生成物に付着させることで、布等による水拭きや乾拭き等で容易に清掃メンテナンス出来るものである。
【0019】
【実施例】
(実施例1)
以下本発明の第1の実施例を添付図面に基づいて説明する。なお従来例と同一構成部分については同一の符号を付して、説明を省略する。
【0020】
21は本体外壁表面となる面に二酸化チタンを主成分とする光触媒層を塗装等によって施したフロントグリル、22は同様にして本体外壁表面となる面に光触媒処理を施した本体前、23は同様にして本体外壁表面となる面に光触媒処理を施した本体後で、紫外線光を透過させる透明な樹脂材料で形成されている。24はモーター7に連結されたファンで、同様にして外周全面に光触媒処理が施されている。25は同様にして表面に光触媒処理を施した格子状の排気口12aを有する排気口グリルである。
【0021】
上記構成による作用は以下の通りである。フロントグリル21、本体前22、本体後23、排気口グリル25から成る本体外壁表面に光触媒処理を施したことにより、空気清浄器本体が運転されている状態、停止されている状態に拘らず、光触媒処理が施された面に紫外線を含む太陽光又は蛍光灯が照射されると光触媒が活性化されて、活性酸素が発生する。この強い酸化力により光触媒処理が施された面、つまり本体外壁表面に接触している空気中の有機物を分解し、人体に有害な微生物を殺傷する。
【0022】
また光触媒が活性化されると、本体の周囲に漂って本体外壁表面に接触している空気中の一酸化窒素(NO1 )、二酸化窒素(NO2 )、亜硫酸ガス(SO2 )等の有害ガス成分が酸化され、硝酸イオン(NO3 )、硫酸イオン(SO3 )等のイオン化した酸化生成物に変えられ、光触媒処理を施した面に吸着される為、有害ガス成分を除去することが出来る。又、鉄系金属酸化物は前記イオンと結合して塩を生成し、酸化生成物を化学的に捕捉する為、有害ガス成分の除去効果をより一層高めるものである。
【0023】
また、上記に示す様に、光触媒との接触反応によって本体周囲の有害ガス成分が酸化されて出来た酸化生成物が光触媒処理を施した面に付着される為、たばこの煙やその他の汚れが光触媒処理を施した本体外壁面に付着するのが防止され、また付着したとしても本体外壁面から剥離しやすい酸化生成物に付着される為、布等で水拭き、または乾拭きしただけで容易に本体外壁面を清掃することが出来る。
【0024】
次に、空気清浄器本体が運転されている状態では、フロントグリル21、排気口グリル25から成る吸排気口を構成する部材表面に光触媒処理を施すことにより、同様にして、光触媒処理を施したフロントグリル21の吸気口1a及び排気口グリル25の排気口12aを通過して、本体に吸排気される空気流中の殺菌と有害ガス成分が除去される。
【0025】
また、同様にして、たばこの煙やその他の汚れが光触媒処理を施したフロントグリル21、排気口グリル25の格子部の面に付着するのを防止し、また付着したとしても剥離しやすい酸化生成物に付着される為、布等で水拭き、または乾拭きしただけで容易に清掃することが出来る。
【0026】
そして、透明な材料等で形成された本体後23を紫外線光が透過して、外周全面に光触媒処理が施されたファン24に照射される為、同様にして、光触媒処理を施したファン24の表面に接触しながら流れる空気中の殺菌と有害ガス成分が除去される。
【0027】
(実施例2)
次に本発明の第2の実施例を、図3、図4を用いて説明する。なお上記実施例と同一構成部分については同一の符号を付して、説明を省略する。
【0028】
26は本品を形成する樹脂材料に二酸化チタンを主成分とする光触媒材を練り込むことによって同光触媒処理を施したフロントグリル、27は同様にして光触媒処理を施した本体前、28は同様にして光触媒処理を施した本体後で、紫外線光を透過させる透明な樹脂材料で形成されている。29はモーター7に連結されたファンで、同様にして光触媒処理が施されている。30は同様にして光触媒処理を施した格子状の排気口12aを有する排気口グリルである。
【0029】
上記構成による作用は、構成部品を形成する樹脂材料に二酸化チタンを主成分とする光触媒材を練り込むことによって同光触媒処理を施した為、上記第1の実施例と同様の効果が得られるものである。
【0030】
なお、本実施例では、二酸化チタンを主成分とする光触媒を用いているが、他のものでもよく要は、光触媒との接触反応により殺菌と有害ガス成分を酸化させて、光触媒処理を施した面に吸着させることにより有害ガス成分を除去するようにすればよい。
【0031】
また、本実施例では、モーターファンから成る電動送風装置及びフィルターから成る集塵装置を用いているが、他のものでもよく、同様の効果が得られるのは言うまでもないことである。
【0032】
さらには、本実施例で既に記載したように、集塵装置のフィルター11を脱臭用の活性炭フィルター11aと集塵用の帯電フィルター11bより形成しており、脱臭器としての機能を含んだ空気清浄器について記載したものであり、当然脱臭器単機能のものであっても同様の効果が得られるのは言うまでもない。
【0037】

The operation of the above configuration is as follows. Regardless of whether the air purifier main body is in operation or stopped, the surface of the outer wall of the main body including the front grille 21, front body 22, rear body 23, and exhaust port grill 25 is subjected to photocatalytic treatment. When the surface subjected to the photocatalyst treatment is irradiated with sunlight or a fluorescent lamp containing ultraviolet rays, the photocatalyst is activated and active oxygen is generated. This strong oxidizing power decomposes organic matter in the air that is in contact with the surface subjected to photocatalytic treatment, that is, the outer wall surface of the main body, and kills microorganisms harmful to the human body.
[0022]
In addition, when the photocatalyst is activated, harmful substances such as nitrogen monoxide (NO 1 ), nitrogen dioxide (NO 2 ), and sulfurous acid gas (SO 2 ) in the air that floats around the body and contacts the outer wall surface of the body Gas components are oxidized and converted to ionized oxidation products such as nitrate ions (NO 3 ) and sulfate ions (SO 3 ), and are adsorbed on the surface subjected to photocatalytic treatment, so that harmful gas components can be removed. I can do it. In addition, the iron-based metal oxide forms a salt by combining with the ions, and chemically captures the oxidation product, thereby further enhancing the effect of removing harmful gas components.

It is prevented from adhering to the outer wall surface that has been subjected to photocatalyst treatment, and even if it adheres, it adheres to an oxidation product that easily peels off from the outer wall surface of the main body, so it can be easily wiped with a cloth or the like. The outer wall surface of the main body can be cleaned.
[0024]
Next, in a state where the air purifier main body is in operation, the photocatalyst treatment was performed in the same manner by subjecting the surface of the member constituting the intake / exhaust port composed of the front grille 21 and the exhaust port grille 25 to photocatalyst treatment. The sterilization and harmful gas components in the air flow passing through the intake port 1a of the front grille 21 and the exhaust port 12a of the exhaust port grill 25 are sucked into and exhausted from the main body.
[0025]
Similarly, it is possible to prevent cigarette smoke and other dirt from adhering to the surface of the lattice portion of the front grille 21 and the exhaust grille 25 subjected to the photocatalyst treatment, and even if they adhere to each other, it is easy to peel off. Because it adheres to things, it can be easily cleaned by simply wiping with a cloth or dry wiping.
[0026]
Then, ultraviolet light is transmitted through the rear part 23 formed of a transparent material or the like and irradiated to the fan 24 whose photocatalyst treatment has been performed on the entire outer periphery. Sterilization and harmful gas components in the flowing air while contacting the surface are removed.
[0027]
