In this way, air from which odors have been removed is blown upward from the housing, so that when the air purifier A is positioned near the odor source, the odor is removed above the odor source.

Abstract
Description
そして、臭気を吸着した脱臭部の吸着材が、加熱部により加熱されることで、臭気成分が除去される。その結果、吸着材の脱臭機能を回復させることができる(例えば、特許文献1)。
従って、このような構造では、脱臭部に室内空気を通過させても、一度に大幅に臭気を除去することが困難であることから、人が室内空気の臭気が減少したと感じることができるようになるまで、長い時間の間、空気清浄機を運転する必要がある。
従って、このような構造では、消臭部を流れる室内空気に含まれた臭気を吸着材が十分に吸着しきれない状態で、空気清浄機から室内へと空気が排出されることになり、人が室内空気の臭気が減少したと感じることができるまで、長い時間の間、空気清浄機を運転する必要がある。
これにより、ヒーターに近い吸着材の部位は、効率よく加熱することがでるので臭気を除去できるが、ヒーターから離れた吸着材の部位は、ヒーターからの熱が効率よく伝わらない恐れがあり、確実に臭気を除去しきれない可能性がある。
従って、このような構成では、吸着材の臭気を吸着する能力を十分に回復させることができないことから、空気清浄機の脱臭機能の低下を招く恐れがある。
以下、図面を参照して本発明の実施の形態1について説明する。
図1~図6を参照すると、本実施の形態に係る空気清浄機Aは、外郭を成す筐体である本体ケースCと、この本体ケースCに設けられる脱臭部60などの各種機能部品により構成されている。
この本体ケースCは、樹脂により形成された箱形状を成しており、前パネル10と前ケース20と後ケース40などの複数の部品により構成されている。
そして、この仕切板23には、後方に向いて開口する円形の後開口24が形成されている。つまり、前ケース20は、前開口22と後開口24とが連通した状態となっている。 尚、仕切板23の後開口24は、後述する送風ファン44のファン開口44dの周囲にベルマウスを形成している。
また、フレーム21の上辺は、左右の2辺より前方に突出することで、上突出部28が形成されており、上辺の上部の前側には、複数の操作ボタンや表示部を形成するLEDなどからなる操作部26が設けられている。
そして、この操作部26に対応して、フレーム21の上辺の上部内側には、これらの操作ボタンやLEDが実装されている操作基板(図示せず)が設けられている。尚、この操作基板は、後述する制御手段47に電気的に接続されている。
また、前パネル10の前面に、左右方向に延びるスリットを形成することにより、前パネル10の前後方向に連通する空気吸込口11(以下、吸込口11)が形成されている。つまり、前パネル10は、前後方向に貫いて空気が流れることが可能なように、通気性が確保されている。
そして、後面43には、室内空気を空気清浄機内部に取り込むための送風手段である送風ファン44と、この送風ファン44から流下する空気を吹出口42へと導く風路を形成するスワロール形状の仕切45とが設けられている。
この送風手段である送風ファン44は、制御手段47に接続され、制御手段47により回転・停止・回転数が制御されている。この様に送風ファン44は、制御手段47に制御されることで、風量や風速などの送風能力が制御されている。
更に、後ケース40の内側の上部であって、吹出口42の近傍には、吹出口42から室内に向けて吹き出す空気の風向を変えたり、吹出口42を閉じたりするルーバー46が設けられている。
尚、吹出口42の開口部分には、ルーバー46を直接触れられないように、格子が取付けられている。
そして、送風ファン44は、後ケース40の後面43に取付けられている。送風ファン44が取付けられた状態において、送風ファン44の羽44aを回転駆動させるモーター44bは、その回転軸44cの向きが、前方を向き、水平方向に伸びた状態となっている。
このように送風ファン44を後ケース40に取付けることで、送風ファン44は、回転軸44cの軸方向の前方を向くファン開口44dから空気を吸込み、送風ファン44の上方を含む、送風ファン44の径方向に空気を吐き出す。
つまり仕切板45は、送風ファン44の周囲を囲み、端部が空気吹出口42と接続するように袋状となるように後ケース40に配置されている。
そして、ルーバー46は、複数の板状の風向板46aが、空気吹出口42の開口に所定の間隔を空けて、それぞれ平行となるように並んで配置されており、それぞれの風向板46aは、この風向板46aの両端に形成された軸46dで、吹出口42に軸支されている。
また、枠体61の内部には、枠体61の開口を遮るように(開口を前後に仕切るように)中仕切板65が設けられている。
また、開口65aの前側には、開口65a内に空気が流入可能な枠65hが設けられている。この枠65hは、後述する脱臭エレメント62に使用者が直接触れることを防止するためのものである。
このガイド部65eの縁には、開口65aの内方に突出するように、後述する脱臭エレメント62をこのガイド部65eに取付けた際に、脱臭エレメント62を受ける受部65fが設けられている。
尚、この蓋体65dはステンレスにより形成されており、中仕切板65の後面側(裏面側)から、梁部65cにネジなどにより固定される。
尚、蓋体65dには、熱放射率を向上させるための黒色の耐熱塗装が施されている。
この触媒は、マンガン系(例えば、神鋼アクテック株式会社製のマンガン系脱臭用触媒)や白金系を用いたものなど、臭気(特に、アンモニアやメチルメルカプタンや硫化水素の臭気)を吸着する性質を有する触媒を用いる。
このような触媒は、臭気成分を吸着すことにより、触媒の作用による酸化分解が生じ、臭気成分を臭いがしない成分へと分解する。特にこのような触媒は、加熱することにより臭気成分の分解スピードが早くなる特性がある。
ここで、上記のように様に脱臭エレメント62は、ハニカムコアにより形成され、前面に設けられたエレメントフレーム62aには所定の開口が形成されているので、脱臭エレメント62の内部を前後方向に貫いて空気が流れることができる。
このギア部62bを含む脱臭エレメント62の直径は、中仕切板65に形成された円形状の開口65aの直径より大きくなるように構成されている。
このヒーターユニット63aは、制御手段47に電気的に接続されており、空気清浄機Aの状態に応じて通電制御されるものである。
つまり、ユーターユニット63aは、ヒーター部63gで生じた熱を板状の発熱部63fが受け、板面全体から熱を放射することにより、対向する脱臭エレメント62をムラが少なく加熱する。
このように、臭気の捕集能力回復の為の加熱工程を、60分以内に行うことができるので、使用者は空気清浄機Aを用いた作業の合間などに、脱臭エレメント62の臭気の捕集能力の回復工程を行うことができる。
このPTCヒーターは、自己温度制御性があり、外部からの温度制御を必要としないことから、サーモスタットのように断続的制御を行わないので、火花やノイズが発生せず、安定して使用することができる。
凹部63cは、ヒーターユニット63aの平面形状と一致した扇形状を成しており、内部にヒーターユニット63aを凹部63cの開口に臨ませた状態でヒーターユニット63aが設けられている。フランジ部63dには、加熱ユニット63を所定の位置に取り付ける際に螺子を貫通させるための螺子穴63eが形成されている。
以上のように構成される加熱ユニット63は、平面形状がヒーターユニット63aの発熱部63fの形状に合わせて、扇形状に構成されており、凹部63cの開口も扇形状に構成されている。
駆動手段64は、モーター64aと、このモーター64aを保持するブラケット64bからなる。モーター64aの回転軸には、ギアが取付けられている。また、モーター64aは、制御手段47に電気的に接続されており、空気清浄機Aの状態に応じて通電制御されるものである。
まず、枠体61の裏面より、中央支持体65bに設けられた軸65jに、脱臭エレメント62の開口部62cが軸受となって回転自在に嵌り込む。
そして、ガイド部65eの縁には、開口65aの内方に突出するようにして、受部65fが形成されている。受部65fは、脱臭エレメント62を受ける受部であり、脱臭エレメント62の回転方向の動きを大きく阻害しない程度に、脱臭エレメント62を、後方(裏面)よりガイド部65eに保持する。
尚、中央支持体65bに設けた軸65jと脱臭エレメント62の開口部62aを、上記のように軸と軸受の関係となるように構成しなくても、脱臭エレメント62をガイド部65eにより保持する構造でもよい。
まず、加熱ユニット63は、脱臭エレメント62の中心から下側の部位を跨いで脱臭エレメント62の回転を妨げないように配置される。
この状態において、加熱ユニット63のヒーターユニット63aが脱臭エレメント62に直接近接して対向するように、ヒーターユニット63aが設けられた凹部63cの開口が前方を向いている。
尚、この状態において、加熱ユニット63と蓋体65dは、脱臭エレメント62を介して向かい合う位置関係となっている。
また、加熱ユニット63と蓋体65dとが向かい合って枠体61に配置されるので、加熱ユニット63と蓋体65dの間に脱臭エレメント62を介在させた状態で、ヒーターユニット63aの熱を留める空間が形成される。更に、発熱部63fは、熱の放射率を向上させる塗装が施されているので、ヒーター63gから受けた熱を効率よく放射する。
これにより、加熱ユニット63は、対向する脱臭エレメント62の部位を局所的に効率よく加熱することができるように構成されている。
また、駆動手段64の配置位置は、中仕切板65の裏面であって、開口65aと中仕切板65の角65gとに挟まれた部位である。更に、この駆動手段64を設ける部位は、4つある角65gの内、加熱ユニット63から離れた上方に位置する角65gと開口65aにより挟まれた部位であるとよい。
つまり、加熱ユニット63と脱臭エレメント62の相対的位置関係を変更可能とすることができる。
また、開口65aと角65gとに挟まれた位置に駆動部64を設けたので、長方形の中仕切板65に形成された開口65aの周囲のデットスペースを有効に利用できる。更に、加熱ユニット63から離れた位置に駆動手段64を設けたので、加熱ユニット63から生じる熱の影響を駆動部64が受けにくい構造とすることができる。
まず、後ケース40は開口41を前方に向けて、前ケース20の後面に取付けられる。この時、後ケース40に設けられた送風ファン44の開口44dは、前ケース20に設けられた仕切板23に形成された後開口24と、対向した位置関係となっている。また、後開口24の開口中心は、送風ファン44の回転軸の軸心と、前後に一致している。
このように脱臭部60が前ケース20に取付けられた状態において、脱臭部60の後面側(加熱ユニット63が取付けられている位置側)が、前ケース20の後開口24を向くように配置され、脱臭エレメント62と後開口24の間に、加熱ユニット63が位置することになる。
加熱ユニット63は、このようにして形成された間隔Dの部位に位置している。
そして、プレフィルター13の前面側に、前ケース20の上突出部28と下突出部25とに挟まれて、前パネル10が設けられることで、空気清浄機Aが構成される。
また、プレフィルター13は、HEPAフィルターで空気をろ過する前に、あらかじめ空気に含まれる大きな塵埃を取っておく目の粗いフィルターであり、HEPAフィルターの効果を長期間保つ為のものである。
まず、使用者が操作部26を操作することで、制御手段47に対して入力を行うことにより、空気清浄機Aの運転を行う所定のプログラムが実行される。
吸込口11から取り込まれた空気は、空気清浄機Aの内部を後方へと流れ、プレフィルター13で大きな塵埃を取り除いた後、HEPAフィルター12で微細な塵埃を取り除く。
尚、「空気から臭気が取り除かれる」とは、空気から完全に臭気が無くなる状態のみならず、空気の脱臭エレメント62を通過する前の状態から臭気が減少した状態も含む。
ここで、上記のように空気清浄機Aを運転し続けることにより、脱臭エレメント62には、吸着した臭気が蓄積されていくことになり、吸着した臭気が増えるに従って、脱臭エレメント62の脱臭能力が低下していく。
送風ファン44へと流れる空気は、送風ファン44の軸方向前方から周囲を羽44aに囲まれたファン開口44dの内部へと流下し、送風ファン44の上方を含む送風ファン44の径方向へと送風ファン44の外部に吐き出される。
このように通風路Rは、吸込口11から水平方向に空気清浄機本体の後部へと繋がり、この後部で上方へと向きを変えて吹出口42へと至る風路である。
これにより、脱臭エレメントまで空気の流れがまっすぐで、各フィルター面に垂直に空気が当たるので空気の流れがよい構成となっている。
Y≧0.6X
となるように構成されている。
制御手段47は、所定のタイミング、例えば、運転開始又は前回行った脱臭エレメント62の脱臭性能回復動作からの累積運転時間が所定の時間を超えた場合、次のように脱臭性能回復動作を行う。
この脱臭エレメント62の加熱温度及び加熱時間は、脱臭エレメント62に吸着した臭気を除去させるのに十分な温度と時間である。
また、脱臭エレメント62は、ヒーターユニット63aと蓋体63dとに挟まれて位置しているので、これら部材から放射される熱が、脱臭エレメント62の近傍に留まりやすく、より効率よく脱臭エレメント62を加熱することができる。
この動作により、加熱ユニット63と対向していた脱臭エレメント62の加熱処理が終了した部位が、加熱エレメント63に対して回転方向にずれる。
これにより、加熱処理が完了している脱臭ユニット62の部位が、加熱ユニット63と蓋体63dに挟まれた位置から外れると共に、新たに臭気を多く吸着した脱臭エレメント62の部位が、加熱ユニット63と蓋体63dとに挟まれた部位に位置することとなる。
また、脱臭ユニット62を動かすタイミングは、加熱処理の後、直ぐに行ってもよく、また、次に行う空気清浄運転の直前に行ってもよい。
本実施の形態のように、脱臭エレメント62と、この脱臭エレメント62とを局部的に加熱する加熱ユニット63との相対的位置関係を変更可能に構成することにより、加熱ユニット63を小型化することができる。
この加熱ユニット63の小型化のメリットは、例えば、脱臭エレメント62の全域を確実に加熱処理できるように、脱臭エレメント62の全域に対面するような、大型のヒーターを配置する必要がなく、構造の簡略化やコスト低減を可能とする。
つまり、常に脱臭エレメント62が加熱ユニット63と対向する部位は、限られた部分で済むことから、加熱ユニット63が脱臭エレメント62を流れる空気の流れの妨げを最小限ですむ。これにより、脱臭エレメント62に対して、より多くの空気を流すことが可能であり、より多くの臭気を一度に空気中から取り除くことができる。
これにより、脱臭エレメント62の各部位間の加熱ムラを少なくでき、脱臭エレメント62の脱臭能力を効率よく回復することが可能である。
このように構成することにより、臭気の発生源に対して、大きく開口する吸込口11を対向させやすいので、より速く臭気を吸込み、室内空気から臭気を除去することができる。
また、吹出口11が本体の側面、天面、又は背面のいずれかに形成されるので、臭気の発生源に清浄された空気が流れ難く、臭気の拡散を防止することができる。
これにより、ヒーターユニット63a発熱する部位である加熱ユニット63が本体ケースCの内部を動かないことから、発熱させるための電源を供給する配線の取り回しや高温の部位が本体ケースCの内部で位置を変えることによる本体ケースC内部の広範囲にわたる熱対策を考慮する必要がない。
また、脱臭エレメント62が回動することで、加熱ユニット63と対向する面を変えるので、1つの方向にだけ脱臭エレメント62を動かすだけで、ムラ無く脱臭エレメント62の全面を加熱ユニット63に対向させることができる。
つまり、本体ケースCの内部の脱臭エレメント62の配置領域を小さくすることができる。
これにより、より多くの空気が脱臭エレメント62を通って流れることができるので、脱臭力を維持しながら風量を大きくすることができる。
特に本実施の形態であれば、短時間の間に、より多くの空気から臭気を取り除くことができるので、病院や介護施設など多くの人が利用する場所における介護などの臭いのトラブルを迅速に解決することが可能である。
このように構成されているので、脱臭エレメント62と送風ファン44の開口44dの周囲で生じる圧損(空気の流れの損失)を低減するために設けられたスペースを、加熱ユニット63の配置位置として用いることができる。
また、上記のケース63bの形状は扇形となっている。これにより、脱臭エレメント62を覆う面積を必要最小限とすることができる。尚、扇形の開角は、脱臭エレメント62を回転させる際の1回の回転角度を目安に構成されている。
これにより、脱臭エレメント62を加熱する際に、制御手段47により自動的に脱臭エレメント62を回動させて脱臭すべき部位を加熱ユニット63に対向することができる。 つまり、加熱手段である加熱ユニット63は、制御手段47によって脱臭エレメント62を加熱する場合、脱臭エレメント62の所定の領域と対面した状態で、所定時間通電することにより、脱臭エレメント62に吸着した臭気を除去して、脱臭エレメント62の局部的な臭気の捕集力を回復させる。
これにより、脱臭エレメント62の回転から加熱に至る一連の動作を制御手段47により自動的に行うことができる。
つまり、制御手段47は、空気清浄機Aの使用頻度に応じて、この動作を繰返し行い、脱臭エレメント62と加熱ユニット63との相対的位置関係を所定の方向に順次変化させる。
これにより、脱臭エレメント62の全体の臭気の捕集力を維持することができる。
このように構成することにより、本体ケースCの前側から塵埃濾過フィルターを着脱することができるので、大きめな塵埃が付着しやすい塵埃濾過フィルターのメンテナンス性を向上することができる。
このような多翼式ファン(シロッコファン)は、ファンの回転軸方向から空気を取り込み、ファンの径方向へと取り込んだ空気を吐き出すので、室内空気を本体ケースCの前面から後方への直線的な流れを作り出すと共に、吹出口42に向けて効率よく風の向きを変えることができる。
このように、ヒーターユニット63aなどを有するある程度重量がある加熱ユニット63を低い位置に配置することで、空気清浄機Aの重心を低くすることができる。これにより、床面に安定して設置することができる空気清浄機Aを構成することができる。
「B≧0.6A」
となるように構成されている。
この関係は、本体ケースCの正面視の面積に対して、開口65a吸込口が室内空気を最大限取り込める関係であり、より室内空気を多く取り込み脱臭エレメント62へ流すことが可能な空気清浄機を構成することができる。
図15~図17を参照すると、空気清浄機Aは、外郭を筐体となる本体ケースCと、この本体ケースCに設けられる脱臭部60などの各種機能部品により構成されている。
この本体ケースCは、樹脂により形成されており、前パネル10と前ケース20と後ケース40などの複数の部品により構成され、正面及び側面の平面形状が、縦長方形の外殻形状をなしている。
このハンドル91は、その握り部91aの中心軸が本体ケースCの天面中央で、かつ左右方向を向くように設置されている。ハンドル91の本体ケースCに対する前後方向の位置は、加熱ユニット63と送風ファン44との間に位置している。また、握り部91aの床面からの高さLは、700mm以下の範囲に位置するように構成されている。
このように各部が配置された状態において、車輪90は、少なくとも握り部91aの長手方向に回転自在となるように構成されている。
特に、ハンドル91の本位ケースCの前後位置が、加熱ユニット63と送風ファン44との間に位置していることから、重量密度が大きい部位の略中間位置にハンドル91が位置する。これにより、ハンドル91を握って空気清浄機Aを押し引きするときに、重量のバランスが比較的取れた位置を支点に空気清浄機Aを動かすことができる。
従って、使用者が運びやすい空気清浄機Aとすることができる。
このように構成されているので、日本人の成人の指節点高(人が床面に立った状態で、床面から中指指節点までの垂直距離)の平均は、男性が約695mm、女性が約632mm、全体が約662mmであることから、性別に関係なく、使用者が大きくかがむことなく、握りやすいハンドル91の高さとなっている。
このように構成されているので、日本人の成人の肩幅の平均は、男性が約426mm、女性が約394mm、全体が約409mmであることから、性別に関係なく、空気清浄機Aを側方より押し引きする際に、人の肩幅内に納まる。
これにより、空気清浄機Aは、狭い通路や場所においても、移動を容易に行うことができる。
従って、空気清浄機Aを一般家庭の廊下に設置しても、人や物が十分に通るだけのスペースを確保することができる。
従って、空気清浄機Aを介護施設の廊下に設置しても、人や物が十分に通るだけのスペースを確保することができる。
また、一般的に用いられる車椅子は幅が約700mmであることから、介護施設の廊下に空気清浄機Aが設置されていても、車椅子同士のすれ違いが可能である。
この構成は、吸込口11から取り込まれたアンモニア成分などを含む室内空気が、吹出口42から本体外部に吐き出されるときには、アンモニア成分などが約70%以上除去された状態で、本体から室内空間に放出される構成となっている。
尚、空気を一度脱臭エレメントに通すことで、脱臭エレメント62が空気中に含まれる臭気成分を除去する率を臭気成分の一過性除去率(ワンパス除去率)と呼ぶ。
例えば、全く臭気成分を除去しない場合は一過性除去率0%(ワンパス除去率0%)、空気中に含まれる臭気を80%除去する場合は一過性除去率80%(ワンパス除去率80%)、となる。
臭気強度とは、臭気判定士などの専門家により、臭気を嗅覚測定法(官能試験法)で測り、臭いの感じ方を6段階で示したものであり、悪臭防止法における22物質の基準値を設定する際の評価基準として採用されている。この臭気強度は、高い段階から低い段階へ1ランク下がることで、人の嗅覚で臭気の減少が感じられる尺度となっている。
まず、臭気の一過性除去率が50%である従来から用いられている可搬性の空気清浄機を、臭気強度が「4」(アンモニアの臭気濃度が10ppm)の空気中で使用した場合、空気中から臭気を50%取り除かれたアンモニアの臭気濃度が5ppmの空気が本体から放出される。
つまり、臭気の一過性除去率が50%の空気清浄機の場合、臭気強度が「3」には至らない、未だに強い臭いが残った空気が本体から室内空間に放出されることになる。
また、脱臭されていても、人が臭気の減少を感じられない空気を本体から室内空間に吹き出すので、室内の脱臭に時間がかかる上、臭気を室内全体に広げてしまう。
つまり、臭気の一過性除去率が80%の空気清浄機の場合、臭気強度が「3」となった臭気強度が1段階下がった空気が本体から放出されることになる。
また、使用者が臭気の減少を実感することができる空気を、本体から室内空間に吹き出すので、臭気を多く含んだ室内空気をより早く薄めることができ、室内の脱臭をより早く行えると共に、臭気を室内全体に広げてしまうことがない。
尚、風速を約0.15メートル以上とすることで、本体から毎分1立方メートルの清浄空気を放出することができる弱運転を可能としている。
この様に制御された状態の空気清浄機Aについて、使用例1及び使用例2を示した図19を参照して説明する。尚、参考例として、従来の空気清浄機(従来例)についても説明
する。
つまり、壁などの構造物によって区画された所定容積の空間内に、外部から空気清浄機を搬入して用いる場合である。
このような状況において、次の各空気清浄機を用いた場合の経過時間に対する各臭気濃度の変化について説明する。
臭気の一過性除去率が80%であれば、吹出口42から放出される空気の臭気強度が、室内空間の臭気強度より1段階以上低いので、使用者は使用開始から臭気の減少を嗅覚で感じ取ることができる。
そして、1分当りの風量が8立方メートルであると、使用開始から3分後には、吹出口42から放出される空気の臭気濃度が、初期の室内臭気濃度1ppmの1/20である0.05ppmに低下する。これは、臭気強度が2段階低下した値である。
この様に、使用例1の場合、空気清浄機Aの使用開始から5~6分でほぼ無臭と難じる程度に急速に脱臭できるので、病院や介護施設のベッドの周囲で行われる臭気を伴う作業を病室内に拡散することなく行うことができる。
つまり、オムツ交換開始の為に、ベッドを囲むカーテンを閉めてから、交換作業が終了してカーテンを開けるまで、オムツ交換作業と同時に空気清浄機Aを用いることにより、オムツ交換作業が終了した時点で、ほぼオムツ交換に伴う臭気の脱臭を終了させることが可能である。
また、多くの利用者のオムツ交換を行う必要がある施設において、オムツ交換に伴う臭気をほとんど拡散させること無く、効率よく作業を行うことが可能である。
本使用例は、使用例1と比べて風量は少ないが、臭気の一過性除去率が高い例である。
臭気の一過性除去率が90%であれば、吹出口42から放出される空気の臭気強度が、室内空間の臭気強度より1段階以上低いので、使用者は使用開始から臭気の減少を嗅覚で感じ取ることができる。
そして、1分当りの風量が5立方メートルであると、使用開始から2分後には、吹出口42から放出される空気の臭気濃度が、初期の室内臭気濃度1ppmの1/20である0.05ppmに低下する。これは、臭気強度が2段階低下した値である。
本使用例では、室内のアンモニア臭気濃度を1/20まで低下させるのに、使用例1より時間がかかるが、使用開始から2分程度で、吹出口42から放出される空気の臭気濃度を初期の室内臭気濃度の1/20である0.05ppmに低下させることができる。
また、風量を抑えて運転するので、送風ファン44などの運転音を低く抑えることができると共に、運転に伴う消費電力を低く抑えることができる。
なぜなら、可搬可能な程度の大きさに構成された空気清浄機の場合、吹出口42の開口面積に制限がある。従って、空気清浄機Aから放出される風量が増やすということは、吹出口42から放出される空気の風速が速くなり、埃などを巻き上げる原因となる。
また、風量を増やすことは、脱臭エレメント62を通過する風速を早めることになり、脱臭エレメント62の臭気の一過性除去率が低下させてしまう可能性がある。
ここで比較の為、従来から用いられている空気清浄機の参考使用例を説明する。
従来から、可搬性の空気清浄機として、約50%の臭気の一過性除去率のものがある。
このような空気清浄機の場合、吹出口から放出される空気の臭気濃度が0.5ppm程度までしか低下していないので、臭気強度を1段階下げることができず、使用者が使用開始時点では臭気の減少を嗅覚で感じ取ることが難しい。
このように、室内の臭気を減少させるのに、長い時間かかることから、病院や介護施設などでオムツ交換を行う際に用いるものとして、十分のものとは言えない。
これは、室内に設置されたベッド等でオムツ交換を行いに漏れ出す臭気を、迅速に空気清浄機Aの内部に取り込むことが可能な構成である。
これに加え、脱臭エレメント62を通過する空気の毎分あたりの流量が壁などの構造物によって区画された空間の容積の1/5倍以上となるように制御手段が送風手段の風量を制御しているので、室内空間に漂う臭気を短時間のうちに捕集することができる(図19参照)。
そして、空気清浄機において、吸込口11は筐体の横方向に向いてに開口し、その吸込口11の中心を通る水平線の位置が、前記空間の床面上で、30cmから70cmの範囲にあるよい。
このように吸込口11を形成することで、病室などで臭気の発生源となるベッド上からの臭気を効率よく空気清浄機Aの内部に取り込むことができる。
このように、臭気を除去した空気を筐体の上方へ吹き出すので、臭気の発生源の近傍に空気清浄機Aを位置して使用している際に、臭気の発生源より上方に臭気を除去した空気を吹き出すことができる。
これにより、臭気の発生源近傍の気流を乱しにくいので、臭気の拡散を防止できると共に、効率よく臭気を含んだ室内空気を空気清浄機Aに取り込むことが可能である。
次に、図11~図12を参照して、本発明の変形例について説明する。尚、実施の形態1と同じ構成については同一の符号を付し、説明を省略する。
脱臭部60を構成する中仕切板65の開口65aの内部中央に位置する中央支持体65bの下方の領域であって、中央支持体65bを中心に、左右に等しく広がる所定の開角により形成される扇形の領域は、中仕切板65の裏側より略扇形状の蓋体65dにより覆われている。
そして、この蓋体65dが上記のように取付けられた状態において、蓋体65dの前面と梁部65cにより囲まれた部位には、断熱材66が設けられる。更にこの断熱材66の前側には、カバー67が設けられる。カバー67は、樹脂により形成されており、中仕切板65の前面側(表面側)から、梁部65cにネジなどにより固定される。
従って、加熱空間の温度を効率よく上げることができ、効率よく脱臭エレメント62を加熱することが可能となると共に、高温になる蓋体65dを使用者が直接触れることができないので、火傷を防止することができる。
また、図13~図14において、吹出口42の開口部分には、通常は格子が取付けられているが、ルーバー46の動きを説明するため、格子を取外した状態で示してある。
まず、吹出口42の近傍にルーバー46は、複数の板状の風向板46aと、この複数の風向板46aをそれぞれ繋いで風向板46aを所定の角度に動かすリンク機構46cと、このリンク機構46cを動かす駆動部(図示せず)から構成されている。
尚、リンク機構46cを動かす駆動部は、後述する制御手段47に接続されており、空気清浄機の状態に応じて、所定のプログラムで駆動されるものであり、これにより、ルーバー46の向きが変更される。
このように、脱臭エレメント62の加熱処理の間、ルーバー46により吹出口42を塞ぐことにより、加熱処理時に生じる脱臭エレメント62からに臭いなどを空気清浄機Aの外部に放出し難くすることができる。
また、吹出口42のみならず、吸込口11にこの吸込口11の開口を開閉するシャッターなどを設けて、脱臭エレメント62の加熱処理時に吸込口11を閉鎖することにより、更に、加熱処理時に生じる脱臭エレメント62からに臭いなどを空気清浄機Aの外部に放出し難くすることが可能となる。
