Description

【０００１】
【発明の属する技術分野】
本発明は、空気中の汚れ物質を除去して清浄にする空気清浄機に関する。本発明に係る空気清浄機は例えば車両の室内の天井側の被取付部に取り付けるのに適する。
【０００２】
【従来の技術】
車両の室内の天井側に取り付ける空気清浄機を例にとって、従来技術について説明する。近年、車両の室内では、車内の空気を清浄にするための空気清浄機が備えられている。この空気清浄機は、吸気口及び吹出口をもち両者の間に空気流路をもつ本体と、本体に配置され空気流路に吸気口から吹出口へ向かう空気流を形成するファンと、空気流路に配置された吸着部とを有する。
【０００３】
この空気清浄機を車両の室内の天井側に取り付けるにあたっては、ボルト締めが一般的であり、片手で空気清浄機を支えながら、他方の片手でボルトを締結して本固定することにしている。
【０００４】
【発明が解決しようとする課題】
ところが上記した従来の空気清浄機を天井側に取り付ける取付構造は、前述したように、ボルト締めが一般的であり、片手で空気清浄機の本体を支えながら、他方の片手でボルトを締結して空気清浄機の本体を本固定することにしているため、取付作業が容易ではない。
【０００５】
本発明はこのような事情に鑑みてなされたものであり、取付作業の簡単化を図ることができ、特に天井側の被取付部に取り付けるのに適する空気清浄機を提供することを課題とする。
【０００６】
【課題を解決するための手段】
本発明に係る空気清浄機は、吸気口及び吹出口をもち両者の間に空気流路をもつ本体と、本体に配置され空気流路に吸気口から吹出口へ向かう空気流を形成するファンと、空気流路に配置された吸着部とを有する空気清浄機において、本体は、本体の先端部に突設され被取付部の差込孔に差し込まれる差込爪部材と、差込爪部材の差込方向と交差する方向に沿って被取付部の押込孔に押し込まれる押込爪部材と、被取付部に本固定される本固定部とを具備しており、被取付部の差込孔に本体の差込爪部材を差し込むと共に、本体の押込爪部材を差込爪部材の差込方向と交差する方向に沿って被取付部の押込孔に押し込むことにより、本体を被取付部に仮保持し、仮保持後に本体の本固定部を被取付部に本固定するようにしたことを特徴とするものである。
【０００７】
【発明の実施の形態】
・本発明によれば、まず、被取付部の差込孔に本体の差込爪部材を差し込むと共に、本体の押込爪部材を差込爪部材の差込方向と交差する方向に沿って移動させて被取付部の押込孔に押し込むことにより、空気清浄機の本体を被取付部に仮保持する。仮保持後に、空気清浄機の本体の本固定部を被取付部に本固定する。このように空気清浄機の本体を被取付部に仮保持した後に、空気清浄機の本体の本固定を行うため、取付作業性が改善される。殊に、被取付部が天井側に位置しておれば、仮保持状態の空気清浄機の本体の自然落下が抑えられるため、本固定時における作業性が改善される。従って、被取付部が車両の室内の天井側に位置している場合であっても、取付作業が容易となる。差込爪部材は本体の先端側に設けられ、押込爪部材は本体の後端側に設けられていることが好ましい。
【０００８】
・差込爪部材は、被取付部の差込孔に差し込まれる機能と、差し込まれた状態で本体の差込爪部材側を支え得る機能とをもつものを意味し、その形状は問わない。押込爪部材は、被取付部の押込孔に押し込まれる機能と、押し込まれた状態で本体の押込爪部材側を支え得る機能とをもつものを意味し、その形状は問わない。
【０００９】
・被取付部は車両の室内の天井側とすることができる。この場合には、被取付部は、天井側の補強部材であるリンフォース部を採用することができるが、これに限定されるものではない。車両の場合、リンフォース部は一般的には金属製である。
【００１０】
・本体は、吸気口及び吹出口の少なくとも一方を形成するグリルと、グリルとで内装壁部の一部を挟持する挟持部とを有する形態を採用できる。この場合には、挟持に伴い、グリルの外端が内装壁部の一部に食い込むように設定されている形態を採用できる。このようにすれば、内装壁部の端末部の剥離等が抑制される。更にグリルの外端が内装壁部に食い込むため、内装壁部とグリルとの境界における段差が低減され易くなり、境界における見栄えが向上する。グリルの外端は食い込み方向に向けて突き出すように曲成されていることが好ましい。
【００１１】
・吸着部は空気を清浄化するために塵埃や臭い物質等を吸着できるものであれば良い。吸着部は、塵埃を捕獲する集塵フィルタ及び光触媒の少なくとも一方で形成できる。
【００１２】
【実施例】
以下、本発明を具体化した実施例について、図面を参照しつつ説明する。
【００１３】
本実施例に係る空気清浄機は自動車等の車両の室内の天井側に取り付けられるものであり、図１に示すように、薄型つまり偏平型の本体１と、本体１のファン室１ａに配置されたファン２と、本体１内のフィルタ収容室１ｂに配置された吸着部として機能する集塵フィルタ３と、本体１内に配置された吸着部として機能する光触媒４０を収容した光触媒ホルダ４とを有する。図１に示すように、本体１は、車体の室内側の前面板１０と車体側の裏面板１１とを一体的に連結して形成された箱形のボディ１２と、室内に対面するようにボディ１２の下面に着脱可能に装備された化粧グリル５とをもつ。
【００１４】
裏面板１１のうちフィルタ収容室１ｂにおいては、図１に示すように、フィルタ収容室１ｂの容積が増加する方向に裏面板１１の壁部分１１ｗを退避させることにより凹み部１５が形成されている。凹み部１５はフィルタ収容室１ｂの上部側に配置されている。図１に示すファン２は、複数の回転羽根２０と、回転羽根２０を駆動させる駆動部２１とを有し、車体の室内Ｒの空気を吸気口５２を介して吸引する。
【００１５】
図１において、前記した化粧グリル５は、本体１のボディ１２の下面の半分以上を覆うと共に多数の吸気口５２を形成する吸気グリル５１と、吸気グリル５１の下流側に設けられた装着用開口５３に着脱可能に装着された吹出グリル５４とを有する。吸気グリル５１は、室内Ｒに対面するように本体１の下面に着脱可能に装着されている。吹出グリル５４は室内Ｒに対面しており、多数の吹出口５５をもつ。吹出グリル５４を吸気グリル５１の装着用開口５３に取り付けるにあたっては、図２から理解できるように、吹出グリル５４の一端側の係止爪５６を吸気グリル５１の被係止部５１ｓに係止させると共に、吹出グリル５４の他端側のグリル係止爪５４ｘを吸気グリル５１の下流部５１ｓのグリル係止爪５１ｘに着脱可能に係止させる。
【００１６】
図１に示すように、本体１内において吹出口５５と吸気口５２との間には空気流路１ｃが形成されている。空気流路１ｃにおいては、上流側から下流側にかけて、吸気口５２に対面するファン２、主として塵埃等を捕獲する集塵フィルタ３、主としてたばこ等の臭い等を除去する光触媒ホルダ４が順に配置されている。
【００１７】
集塵フィルタ３は、空気透過性及び可撓性をもつ薄板状のフィルタ材を山部及び谷部を交互に形成するようにプリーツ状に織り込まれて形成されており、全体外観は実質的に四角箱状をなしており、図２に示すように、上面部３ｕ、下面部３ｄ、側面部３ｅをもつ。図２に示すように、集塵フィルタ３の上流端３ｆの端面３ｆｏは本体１の裏面板１１のフィルタ上流係止部１９に係止されており、これにより空気流路１ｃを流れる空気が凹み部１５内に進入しないようにシールしていると共に、集塵フィルタ３の挿入方向への位置決めを行っている。
【００１８】
図２に示すように、集塵フィルタ３の下流端３ｒは、本体１の裏面板１１に保持されたフィルタ下流係止部１ｘに微量ぶん係止されており、これによっても集塵フィルタ３の挿入方向への位置決め、集塵フィルタ３のがた防止を行っている。
【００１９】
更に、集塵フィルタ３の下流端３ｒには、シール性の向上、集塵フィルタ３のがたつきを一層抑えるためのクッション材３１が一体的に保持されている。
【００２０】
光触媒ホルダ４は、吹出グリル５４及び励起手段４９に対面するように設けられている。光触媒ホルダ４は空気透過性のための窓をもち、着脱可能に互いに一定的に取り付けられた第１ケース４１及び第２ケース４６で薄型つまり偏平型の箱状に形成されており、前述したように多数個の光触媒４０をがたつかないように光触媒４０を高密度で収容している。光触媒４０は微小球状であり、TiO₂を主要成分としている。
【００２１】
図１、図２に示すように、光触媒ホルダ４に対面するように、光触媒ホルダ４の上方に、光触媒４０を励起させる励起手段４９が本体１内に保持されている。励起手段４９は多数個の発光ダイオード４９ｍを並設して形成されており、全体として薄型つまり偏平型をなしている。発光ダイオード４９ｍは窒化ガリウム系光半導体で形成されており、短波長の光（発光波長ピーク：３８０ｎｍ程度）を光触媒４０に照射するものであり、空気流路１ｃに露出している。発光ダイオード４９ｍからの光が照射されると、光触媒４０は励起されて活性化し、光触媒４０に付着しているにおい物質等の物質を分解する作用が高まる。
【００２２】
さて本実施例に係る空気清浄機の取付構造について説明を加える。図１、図３、図４に示すように、空気清浄機の本体１の先端部１ｆの中央域には、１個の差込爪部材８０が本体１の面方向に沿った方向に突出するように設けられている。差込爪部材８０は幅広型であり、比較的広い幅寸法Ｍ１（図３参照）を有する。差込爪部材８０は、図５に示すように、本体１の先端部１ｆから横方向に突設された延設部８０ａと、延設部８０ａの先端に突設された爪機能をもつ差込頭部８０ｃとを備えている。図５に示すように、差込頭部８０ｃは、差込方向の先方に向かうにつれて上向きに突出する突出部分８０ｃｏと、突出部分８０ｃｏの突出方向と逆向き（下向き）に突出する突出部分８０ｃ１とをもつ。即ち、差込爪部材８０は、差込方向と交差する方向においてその両側に突出部分８０ｃｏ、８０ｃ１をもつ。これにより差込爪部材８０の外れ止め性が向上する。差込爪部材８０を本体１の面方向に、つまり矢印Ｆ１方向に沿って本体１と共に移動させると、第１天井側リンフォース部１０１の横長な差込孔１０１ｒに挿入される。なお、差込孔１０１ｒは、差込爪部材８０が本体１から突出している方向（差込爪部材８０の差込方向）に沿って貫通している。
【００２３】
上記したように差込孔１０１ｒに差込爪部材８０が差し込まれた状態では、本体１は本体１の長さ方向（差込爪部材８０の差込方向）に沿って位置調整することができる。また差込孔１０１ｒの内縁１０１ｒｏと差込爪部材８０との間には余裕空間があるため、本体１は本体１の高さ方向にも位置調整することができる。更に本体１は本体１の幅方向にも位置調整することができる。
【００２４】
更に図３、図４に示すように、空気清浄機の本体１の後端部１ｒに２個の取付片８２が並設状態に突設されており、各取付片８２に押込爪部材９０が着脱可能に取り付けられている。押込爪部材９０は合計２個設けられている。図７に示すように、本体１の後端部１ｒに突設された取付片８２には、後方が開放された保持開口８３が形成されている。この保持開口８３は、取付片８２の後端８２ｒに向かうにつれて拡開する拡開開口８４と、拡開開口８４に連通する円形開口８５とで形成されている。押込爪部材９０は樹脂等の弾性材料で形成されており、図６に示すように、軸部９１と、軸部９１の先端に設けられた径大の押込頭部９２と、軸部９１の中間部に径方向に延設されたリップ部９３と、軸部９１の基端部に径方向に延設された抜け止め部９４と、リップ部９３と抜け止め部９４との間に形成された溝９５とを有する。押込爪部材９０を矢印Ｗ１方向（図７参照）に相対移動させ拡開開口８４を経て円形開口８５に挿入する。これにより押込爪部材９０の溝９５が取付片８２に嵌合保持される。差込爪部材８０の差込方向と交差する方向、つまり矢印Ｆ２方向（本体１の高さ方向）に沿って、押込爪部材９０を本体１と共に移動させると、押込爪部材９０の押込頭部９２は、第２天井側リンフォース部１０２の押込孔１０２ｒに強制的に圧入され、係止される。なお、押込孔１０２ｒは、差込爪部材８０の差込方向と交差する方向、つまり本体１の高さ方向に沿って貫通している。
【００２５】
上記したように押込孔１０２ｒに押込爪部材９０が押し込まれた状態では、押込爪部材９０と取付片８２の保持開口８３の内壁面との間には若干の余裕空間があるため、本体１は本体１の長さ方向にも幅方向にも位置調整することができる。なお、図３に示すように、差込爪部材８０及び押込爪部材９０は本体１の長さ方向の両端部に互いに背向するように設けられている
更に図３、図４に示すように、空気清浄機の本体１の上面には、幅方向の両端側には本固定部１３が２個設けられている。本固定部１３は、本体１の長さ方向において差込爪部材８０と押込爪部材９０との間に配置されている。図４から理解できるように、車体の第３天井側リンフォース部１０３には本固定孔１０３ｒが形成されており、本固定孔１０３ｒは、差込爪部材８０の差込方向と交差する方向、つまり本体１の高さ方向に沿って貫通している。なお、本固定孔１０３ｒには樹脂製の本固定用のクリップ１０４が圧入されて予め保持されている。
【００２６】
そして図４に示すように、取付に際しては、タッピング機能をもつ雄ネジ１０１及びボルト頭部１０２を有する取付ボルト１００を用いる。そのボルト頭部１０２を下にした状態で、取付ボルト１００をこれの先端から本固定部１３の挿入孔１４に挿入すると共に、取付ボルト１００のボルト頭部１０２を工具等で回転させることにより、取付ボルト１００の雄ネジ１０１でクリップ１０４にタッピングにより雌ネジ１０５を強制的に形成する。これにより取付ボルト１００の雄ネジ１０１とクリップ１０４の雌ネジ１０５とが螺着する。よって本体１の本固定部１３を車体の第３天井側リンフォース部１０３に本固定することができる。
【００２７】
このように本固定した状態では、雌ネジ１０５と雄ネジ１０１とが螺着して締結されているため、空気清浄機の本体１の必要取付強度は確保される。なお、前記した第１天井側リンフォース部１０１、第２天井側リンフォース部１０２、第３天井側リンフォース部１０３は、車体に補強のため装備されている金属製の部材であり、本発明に係る被取付部を構成する。
【００２８】
空気清浄機を車体の室内Ｒの天井側に取り付ける場合について、更に説明を加える。この場合には、吸気グリル５１と吹出グリル５４とからなる化粧グリル５が本体１から取り外されている状態とする。そして図４から理解できるように、本体１の先端部１ｆの差込爪部材８０を本体１の面方向に沿ってつまり矢印Ｆ１方向（本体１の長さ方向）に沿って本体１と共に移動させることにより、車体側の第１天井側リンフォース部１０１の差込孔１０１ｒに差込爪部材８０を挿入して係止する。この状態では、本体１の後端部１ｒは、本体１の高さ方向に沿って昇降させることができる。
【００２９】
そして、本体１の後端部１ｒを押込爪部材９０と共に、差込爪部材８０の差込方向と交差する方向、つまり矢印Ｆ２方向（本体１の高さ方向）に沿って移動させることにより、押込爪部材９０の押込頭部９２を車体側の第２天井側リンフォース部１０２の押込孔１０２ｒに圧入して係止する。この状態では、空気清浄機の本体１は１個の差込爪部材８０と２個の押込爪部材９０により３点で仮保持される。
【００３０】
本実施例に係る差込爪部材８０は幅広型であるため、幅狭型である場合に比較して、差込爪部材８０は第１天井側リンフォース部１０１の差込孔１０１ｒの周縁に安定的に仮保持されるため、本体１の仮保持性が向上する。なお、上記した仮保持状態では、差込爪部材８０及び押込爪部材９０は、前述したように位置調整可能であるため、車体の第３天井側リンフォース部１０３の本固定孔１０３ｒと本体１の本固定部１３の挿入孔１４との位置合わせを、簡便に行うことができる。
【００３１】
上記したように空気清浄機の本体１を仮保持した状態で、前述したように、取付ボルト１００のボルト頭部１０２を下にした状態で、取付ボルト１００を本固定部１３の挿入孔１４に挿入すると共に、取付ボルト１００のボルト頭部１０２を工具等で回転させる。これにより取付ボルト１００の雄ネジ１０１でクリップ１０４にタッピングにより雌ネジ１０５を形成し、雌ネジ１０５と雄ネジ１０１とを螺着させる。これにより空気清浄機の本体１の本固定部１３を車体の天井側の被取付部である第３天井側リンフォース部１０３に本固定することができる。このように空気清浄機の本体１を本固定した状態では、車体側の被取付部である第１天井側リンフォース部１０１の差込孔１０１ｒに差込爪部材８０が係止していると共に、第２天井側リンフォース部１０２の押込孔１０２ｒに押込爪部材９０が係止しているため、本体１に対する外れ止め性が一層向上する。
【００３２】
上記したように本実施例では、空気清浄機の本体１をこれが自然落下せぬよう天井側リンフォース部１０１,１０２に仮保持した状態で、空気清浄機の本体１を天井側リンフォース部１０３に本固定することができるため、本固定時には、空気清浄機の本体１を作業者またはロボット等で支えていなくても良い。更に作業者またはロボット等は無理な姿勢を強いられることも抑えられるため、取付作業性を向上させ得るばかりか、作業者の安全性の向上にも貢献できる。
【００３３】
ところで、図１、図２に示す天井壁部２００はルーフライニングともよばれ、室内Ｒの内装壁部を構成するものであり、薄い板状をなしており、室内Ｒに対面する意匠性の高い表皮層２０１と、表皮層２０１の裏面に貼り合わされた裏打層２０２とで形成されている。
【００３４】
図１に示すように、本体１の周囲には突起リブ形状をなす複数の挟持部１６が設けられている。上記したように空気清浄機の本体１を第３天井側リンフォース部１０３に本固定した後に、本体１の周囲に天井壁部２００を配置する。その後、吸気グリル５１と吹出グリル５４とからなる化粧グリル５を、本体１の下面部に取り付ける。この結果、図１、図２、図５等に示すように、本体１の周囲に存在する天井壁部２００の端末部２０４をこれの厚み方向に化粧グリル５の吸気グリル５１の外端５１ｐと挟持部１６とで挟持すると共に、天井壁部２００の端末部２０４にこれの下側から吸気グリル５１の外端５１ｐを食い込ませる。このようにすれば本体１の周囲の天井壁部２００の端末部２０４の固定性が向上し、本体１の周囲の天井壁部２００の端末部２０４の剥離を防止するのに有利である。更に、吸気グリル５１の外端５１ｐが天井壁部２００の端末部２０４に食い込んでいるため、車体の室内Ｒの内装材である天井壁部２００の端末部２０４と吸気グリル５１との境界域における段差が低減され、吸気グリル５１と天井壁部２００の端末部２０４との平滑性が向上し、該境界域における見栄えの向上を図り得る。図３に示すように、本体１の周囲には多数の挟持部１６が設けられているため、上記のように挟持部１６を利用した吸気グリル５１の外端５１ｐの食い込み作用は多数箇所で行われ、本体１の周囲における見栄えの向上を図り得る。なお、吸気グリル５１の外端５１ｐは、食い込み性を向上させるために、食い込み方向即ちやや上向きに曲成されている。
【００３５】
本実施例においては、本体１、励起手段４９、光触媒ホルダ４は薄型であるため、空気清浄機の薄型化に貢献でき、車両の室内Ｒにおいても違和感なく天井側に取り付けられ、車体の室内Ｒを広く確保するのに有利である。
【００３６】
なお、空気清浄機を使用する場合には、ファン２を回転させると共に励起手段４９の発光ダイオード４９ｍを発光させる。ファン２の回転により車両の室内Ｒの空気は、吸気グリル５１の吸気口５２から吸引され、空気流路１ｃを流れ、集塵フィルタ３、光触媒４０を経て浄化される。浄化された空気は吹出グリル５４の吹出口５５から室内Ｒに吹き出される。これにより室内Ｒが清浄化される。空気中の塵埃等のように比較的大きい粒子は集塵フィルタ３で捕獲され、空気中の臭い物質等の粒子等のように極微の粒子は光触媒４０に吸着される。光触媒４０に付着された物質は次第に分解除去される。
【００３７】
（その他）
上記した実施例では、差込爪部材８０は幅広型とされているが、これに限られるものではなく、幅狭型でも良く、棒状でも良い。差込爪部材８０の数は１個であるが、これに限らず２個とすることもできる。押込爪部材９０の数は２個であるが、１個でも、３個でも良い。内装壁部は、表皮をもつ積層構造の天井壁部２００で構成されているが、これに限られるものではなく、単層構造でも良い。上記した実施例では、本固定部１３は本体１に２個設けられているが、これに限らず、場合によっては１個でも、３個でも、４個でも、それ以上でも良い。被取付部は車体の補強部材であるリンフォース部に限定されるものではなく、要するに、空気清浄機の本体１を取り付け得る強度を有するものでは有ればよい。上記した実施例では、吸着部として集塵フィルタ３及び光触媒４０の双方を設けているが、これに限らず、集塵フィルタ３及び光触媒４０のうちのいずれか一方でも良い。
その他、本発明は上記し且つ図面に示した実施例のみに限定されるものではなく、要旨を逸脱しない範囲内で適宜変更して実施できるものである。上記した実施例は本発明の概念を例示したものであり、実施例に記載の語句、部材、部材を修飾している語句は、一部であっても、各請求項に記載できるものである。

【発明の効果】
本発明によれば、まず、被取付部の差込孔に空気清浄機の本体の差込爪部材を差し込むと共に、空気清浄機の本体の押込爪部材を被取付部の押込孔に押し込むことにより、空気清浄機の本体を被取付部に仮保持する。仮保持した後に、空気清浄機の本体の本固定部を被取付部に本固定することができる。このように空気清浄機の本体を被取付部に仮保持した後に、空気清浄機の本体を本固定を行うため、本固定の際には、空気清浄機の本体を手腕等で支えておらずとも良く、更に作業者は無理な姿勢を強いられることも抑えられるため、取り付け作業性を向上させ得るはがりか、作業者の安全性の向上にも貢献できる。
【００４０】
更に本発明によれば、空気清浄機の本体が被取付部に取り付けられたときには、グリルの外端と挟持部とで天井壁部等の内装壁部をこれの厚み方向に挟持しつつ、グリルの外端を天井壁部等の内装壁部に食い込ませる。このようにすれば天井壁部等の内装壁部の固定性が向上し、天井壁部等の内装壁部の剥離を防止するのに有利である。更に、グリルの外端が天井壁部等の内装壁部に食い込むため、天井壁部等の内装壁部とグリルの外端との境界域における段差が低減され易くなり、境界域における見栄えの向上を図り得る。

Note that the insertion hole 101r penetrates along the direction in which the insertion claw member 80 protrudes from the main body 1 (the insertion direction of the insertion claw member 80).
[0023]
In the state where the insertion claw member 80 is inserted into the insertion hole 101r as described above, the position of the main body 1 can be adjusted along the length direction of the main body 1 (the insertion direction of the insertion claw member 80). . Further, since there is a marginal space between the inner edge 101ro of the insertion hole 101r and the insertion claw member 80, the position of the main body 1 can also be adjusted in the height direction of the main body 1. Further, the position of the main body 1 can be adjusted in the width direction of the main body 1.
[0024]
Further, as shown in FIGS. 3 and 4, two attachment pieces 82 are projected in a juxtaposed manner at the rear end 1 r of the main body 1 of the air purifier, and a pushing claw member 90 is provided on each attachment piece 82. Removably attached. A total of two pushing claw members 90 are provided. As shown in FIG. 7, a holding opening 83 that is open at the rear is formed in the mounting piece 82 that protrudes from the rear end 1 r of the main body 1. The holding opening 83 is formed by an expanding opening 84 that expands toward the rear end 82 r of the mounting piece 82, and a circular opening 85 that communicates with the expanding opening 84. The pushing claw member 90 is made of an elastic material such as resin.

And a groove 95. The pushing claw member 90 is relatively moved in the direction of the arrow W1 (see FIG. 7) and inserted into the circular opening 85 through the widening opening 84. As a result, the groove 95 of the pushing claw member 90 is fitted and held in the mounting piece 82. When the pressing claw member 90 is moved together with the main body 1 along the direction intersecting the insertion direction of the insertion claw member 80, that is, the direction of the arrow F2 (the height direction of the main body 1), the pressing head of the pressing claw member 90 92 is forcibly press-fitted into the push-in hole 102r of the second ceiling-side reinforcement portion 102 and locked. The push hole 102r penetrates along the direction intersecting the insertion direction of the insertion claw member 80, that is, along the height direction of the main body 1.
[0025]
As described above, in the state in which the pushing claw member 90 is pushed into the pushing hole 102r, there is a slight margin between the pushing claw member 90 and the inner wall surface of the holding opening 83 of the mounting piece 82. The position of the main body 1 can be adjusted both in the length direction and in the width direction. As shown in FIG. 3, the insertion claw member 80 and the pushing claw member 90 are provided so as to face each other at both ends in the length direction of the main body 1.
Further, as shown in FIGS. 3 and 4, two main fixing portions 13 are provided on both ends in the width direction on the upper surface of the main body 1 of the air purifier. The fixed portion 13 is disposed between the insertion claw member 80 and the pushing claw member 90 in the length direction of the main body 1. As can be understood from FIG. 4, a main fixing hole 103 r is formed in the third ceiling side reinforcement portion 103 of the vehicle body, and the main fixing hole 103 r intersects the insertion direction of the insertion claw member 80, That is, it penetrates along the height direction of the main body 1. Note that a resin fixing clip 104 made of resin is press-fitted into the main fixing hole 103r and held in advance.
[0026]
As shown in FIG. 4, when mounting, a mounting bolt 100 having a male screw 101 having a tapping function and a bolt head 102 is used. With the bolt head 102 facing down, the mounting bolt 100 is inserted from the tip of the mounting bolt 100 into the insertion hole 14 of the main fixing portion 13, and the bolt head 102 of the mounting bolt 100 is rotated with a tool or the like. The female screw 105 is forcibly formed by tapping the clip 104 with the male screw 101 of the mounting bolt 100. As a result, the male screw 101 of the mounting bolt 100 and the female screw 105 of the clip 104 are screwed together. Therefore, the main fixing portion 13 of the main body 1 can be main fixed to the third ceiling side reinforcement portion 103 of the vehicle body.
[0027]
In this state, the female screw 105 and the male screw 101 are screwed and fastened, so that the necessary mounting strength of the main body 1 of the air cleaner is ensured. The first ceiling-side reinforcement portion 101, the second ceiling-side reinforcement portion 102, and the third ceiling-side reinforcement portion 103 described above are metal members equipped for reinforcement on the vehicle body. The to-be-attached part which concerns on is comprised.
[0028]
The case where the air cleaner is attached to the ceiling side of the interior R of the vehicle body will be further described. In this case, the decorative grill 5 including the intake grill 51 and the blowout grill 54 is in a state where it is removed from the main body 1. Then, as can be understood from FIG. 4, the insertion claw member 80 of the distal end portion 1 f of the main body 1 is moved together with the main body 1 along the surface direction of the main body 1, that is, along the arrow F <b> 1 direction (the length direction of the main body 1). Thus, the insertion claw member 80 is inserted into the insertion hole 101r of the first ceiling side reinforcement portion 101 on the vehicle body side and locked. In this state, the rear end 1r of the main body 1 can be raised and lowered along the height direction of the main body 1.
[0029]
Then, by moving the rear end 1r of the main body 1 together with the pressing claw member 90 along the direction intersecting the insertion direction of the insertion claw member 80, that is, the direction of the arrow F2 (the height direction of the main body 1), The pushing head 92 of the pushing claw member 90 is press-fitted into the pushing hole 102r of the second ceiling side reinforcement portion 102 on the vehicle body side and locked. In this state, the main body 1 of the air purifier is temporarily held at three points by one insertion claw member 80 and two pushing claw members 90.
[0030]
Since the insertion claw member 80 according to the present embodiment is a wide type, the insertion claw member 80 is formed at the periphery of the insertion hole 101r of the first ceiling side reinforcement portion 101 as compared with the case of the narrow type. Since temporary holding is stably performed, the temporary holding property of the main body 1 is improved. Note that, in the temporary holding state described above, the insertion claw member 80 and the pushing claw member 90 can be adjusted in position as described above, so the main fixing hole 103r of the third ceiling side reinforcement portion 103 of the vehicle body and the main body 1 Alignment with the insertion hole 14 of the main fixing portion 13 can be easily performed.
[0031]
As described above, with the main body 1 of the air purifier temporarily held as described above, the mounting bolt 100 is inserted into the insertion hole 14 of the fixed portion 13 with the bolt head 102 of the mounting bolt 100 turned down. While inserting, the bolt head 102 of the mounting bolt 100 is rotated with a tool or the like. As a result, the female screw 105 is formed on the clip 104 by tapping the male screw 101 of the mounting bolt 100, and the female screw 105 and the male screw 101 are screwed together. As a result, the main fixing portion 13 of the main body 1 of the air cleaner can be permanently fixed to the third ceiling-side reinforcement portion 103 which is a mounted portion on the ceiling side of the vehicle body. In this state in which the main body 1 of the air purifier is permanently fixed, the insertion claw member 80 is locked in the insertion hole 101r of the first ceiling side reinforcement portion 101 which is the attachment portion on the vehicle body side. Since the pressing claw member 90 is locked in the pressing hole 102r of the second ceiling side reinforcement portion 102, the detachment prevention property with respect to the main body 1 is further improved.
[0032]
As described above, in the present embodiment, the main body 1 of the air cleaner is temporarily held by the ceiling-side reinforcement portions 101 and 102 so that the main body 1 of the air cleaner does not fall naturally, and the main body 1 of the air cleaner is attached to the ceiling-side reinforcement portion 103. Therefore, the main body 1 of the air purifier does not have to be supported by an operator or a robot or the like. Furthermore, since an operator, a robot, or the like can be prevented from being forced into an unreasonable posture, not only can the installation workability be improved, but also the worker's safety can be improved.
[0033]
By the way, the ceiling wall part 200 shown in FIG. 1 and FIG. 2 is also called roofing, and constitutes the interior wall part of the room R, has a thin plate shape, and has a high design surface facing the room R. A layer 201 and a backing layer 202 bonded to the back surface of the skin layer 201 are formed.
[0034]
As shown in FIG. 1, a plurality of sandwiching portions 16 having a protruding rib shape are provided around the main body 1. As described above, after the main body 1 of the air cleaner is permanently fixed to the third ceiling-side reinforcement portion 103, the ceiling wall portion 200 is disposed around the main body 1. Thereafter, the decorative grill 5 including the intake grill 51 and the blowout grill 54 is attached to the lower surface portion of the main body 1. As a result, as shown in FIGS. 1, 2, 5, etc., the end portion 204 of the ceiling wall portion 200 existing around the main body 1 is connected to the outer end 51 p of the intake grille 51 of the decorative grille 5 in the thickness direction thereof. While being pinched by the pinching portion 16, the outer end 51 p of the intake grill 51 is bitten into the terminal portion 204 of the ceiling wall portion 200 from below. By doing so, the fixing property of the terminal portion 204 of the ceiling wall portion 200 around the main body 1 is improved, which is advantageous in preventing the separation of the terminal portion 204 of the ceiling wall portion 200 around the main body 1. Furthermore, since the outer end 51p of the intake grille 51 bites into the terminal part 204 of the ceiling wall part 200, in the boundary area between the terminal part 204 of the ceiling wall part 200 and the intake grille 51, which is an interior material of the interior R of the vehicle body. A level | step difference is reduced, the smoothness of the inlet grill 51 and the terminal part 204 of the ceiling wall part 200 improves, and the improvement of the appearance in this boundary area can be aimed at. As shown in FIG. 3, since a large number of clamping portions 16 are provided around the main body 1, the biting action of the outer end 51p of the intake grille 51 using the clamping portions 16 is performed at a number of locations as described above. Therefore, the appearance around the main body 1 can be improved. The outer end 51p of the intake grill 51 is bent in the biting direction, that is, slightly upward in order to improve the biting property.
[0035]
In the present embodiment, since the main body 1, the excitation means 49, and the photocatalyst holder 4 are thin, it can contribute to the thinning of the air purifier, and can be attached to the ceiling side in the vehicle interior R without a sense of incongruity. It is advantageous to ensure a wide range.
[0036]
In addition, when using an air cleaner, the fan 2 is rotated and the light emitting diode 49m of the excitation means 49 is caused to emit light. As the fan 2 rotates, the air in the vehicle interior R is sucked from the intake port 52 of the intake grill 51, flows through the air flow path 1c, and is purified through the dust collection filter 3 and the photocatalyst 40. The purified air is blown out into the room R from the outlet 55 of the outlet grill 54. Thereby, the room R is cleaned. Relatively large particles such as dust in the air are captured by the dust collecting filter 3, and extremely fine particles such as particles of odorous substances in the air are adsorbed by the photocatalyst 40. The substance attached to the photocatalyst 40 is gradually decomposed and removed.
