- a blower device comprising: a casing (11) forming an outer shell; an inside air intake port (23) provided in the casing for sucking inside air into the inside of the casing; an outside air intake port (24) that is provided and that sucks outside air into the interior of the casing; an intake damper (29) that selectively closes the inside air intake port or the outside air intake port; a trapping section (31) that captures floating matter floating in the air sucked into the housing; a first ultraviolet irradiation section (27) that irradiates the trapping section with ultraviolet rays; a mounting part (26) fixed to the inside air inlet, provided so as to cover the inside air inlet, and to which the first ultraviolet ray irradiation part is attached, the first ultraviolet ray irradiation part when the inside air inlet is viewed from above. In some cases, it is provided so as to overlap with the inside air intake port.

- the region of the trapping section on the outside air inlet side is weakly irradiated with ultraviolet rays from the first ultraviolet irradiating section, but is strongly irradiated with ultraviolet rays from the second ultraviolet irradiating section that is reflected by the reflecting section. Therefore, variations in the intensity of the ultraviolet rays irradiated onto the trapping section can be reduced.
- the reflecting section collects reflected ultraviolet rays in the trapping section in a state where the intake damper closes the outside air inlet. It's recessed like that.
- the reflecting section is recessed so that the reflected ultraviolet rays are concentrated on the capturing section.
- more ultraviolet rays can be irradiated onto the trapping section, so that viruses and the like attached to the floating matter captured by the trapping section can be more suitably inactivated. Therefore, the air blown into the vehicle interior can be purified.

Abstract
Description
本開示の一態様に係る送風装置は、車両外部の空気である外気又は車室内の空気である内気の温度を調整し前記車室内に吹出す温度調整装置に対して、外気又は内気を供給する送風装置であって、外殻を為す筐体と、前記筐体に設けられ、前記筐体の内部に内気を吸入する内気吸入口と、前記筐体に設けられ、前記筐体の内部に外気を吸入する外気吸入口と、前記内気吸入口又は前記外気吸入口を選択的に閉鎖するインテークダンパと、前記筐体の内部に設けられ、前記筐体の内部に吸入した空気中を浮遊する浮遊物を捕捉する捕捉部と、前記捕捉部に対して紫外線を照射する第1紫外線照射部と、前記筐体に固定され、前記内気吸入口を覆うように設けられ、前記第1紫外線照射部が取り付けられる取付部と、を備え、前記第1紫外線照射部は、前記内気吸入口を平面視した際に、前記内気吸入口と重複するように設けられている。
第1紫外線照射装置27は、第2紫外線照射装置28よりも上方に設けられている。第1紫外線照射装置27は、傾斜部20におけるZ軸方向の中心よりも上方に設けられている。第2紫外線照射装置28は、傾斜部20におけるZ軸方向の中心よりも下方に設けられている。
また、第1紫外線照射装置27は、第2紫外線照射装置28よりもX軸方向の中心(傾斜部20の中心)側に設けられている。第1紫外線照射装置27は、内気吸入部21におけるX軸方向の中心よりも他側(図2における紙面右側)に設けられている。第2紫外線照射装置28は、内気吸入部21におけるX軸方向の中心よりも一側(図2における紙面左側)に設けられている。
また、第2紫外線照射装置28は、図2の矢印U2に示すように、紫外線を後述の反射板29cに向かって照射する。反射板29cによって反射した紫外線の一部は、矢印U3で示すように、フィルタ31の所定の領域Aに向かって照射される。
本実施形態では、内気吸入口23の中心からフィルタ31の中心までの距離Lが略100mmとされている。また、ベルマウス上の風が多く通過する範囲の直径D(図3参照)は、200mm以上であって250mm以下とされている。このため、第1紫外線照射装置27からフィルタ31の中心に向かって紫外線を照射した場合、中心から30度の範囲に上述の所定の領域Aを含めることができる。このため、粒子等が捕捉され易い所定の領域Aに対して、より効果的に紫外線を照射することができる。
インテークダンパ29は、Y軸方向に沿って延在する円柱状の回転軸部29aと、一端が回転軸部29aに固定されている板状の閉鎖部29bと、を有する。回転軸部29aは、内気吸入部21と外気吸入部22との接続部分の下面に、Y軸方向に沿って延在する中心軸線を中心として所定の角度回動可能に固定されている。閉鎖部29bは、内気吸入口23及び外気吸入口24よりも大きく、内気吸入口23及び外気吸入口24を閉鎖可能とされている。
図3に示すように、フィルタ収容部30の内部には、X軸方向及びY軸方向の略全域に亘ってフィルタ31が収容されている。フィルタ31は、流路断面の略全域を覆うように設けられている。
本実施形態では、図2に示すように、第1紫外線照射装置27は、X軸方向に紫外線を照射している。このように、山状の部分の延在方向と同じ方向から紫外線を照射することで、山状の部分に紫外線を遮られ難くすることができる。したがって、谷状の部分にも紫外線を好適に照射することができる。
ファン41は、図3に示すように、ファン吸い込み口44の縁に沿って並んで等間隔に配置された複数の羽根42を有する。ファン41が駆動することで、複数の羽根42が回転し、内気吸入口23又は外気吸入口24を介して筐体11内に内気又は外気を吸入する。
ファン収容部40は、ファン吸い込み口44と跨ぐように、板状の補強部材43が設けられている。2枚の補強部材43は、平面視で十字となるように配置されており、フィルタが吸い込まれることを防止している。
制御部は、外気モードにおいてインテークダンパ29が内気吸入口23を閉鎖している状態において紫外線の照射を停止するように第1紫外線照射装置27及び第2紫外線照射装置28を制御する。また、制御部は、内気モードにおいて、インテークダンパ29が外気吸入口24を閉鎖している状態において紫外線を照射するように第1紫外線照射装置27及び第2紫外線照射装置28を制御する。
主記憶装置は、例えば、キャッシュメモリ、RAM(Random Access Memory)等の書き込み可能なメモリで構成され、CPUの実行プログラムの読み出し、実行プログラムによる処理データの書き込み等を行う作業領域として利用される。
二次記憶装置は、非一時的なコンピュータ読み取り可能な記録媒体(non-transitory computer readable storage medium)である。二次記憶装置は、例えば、磁気ディスク、光磁気ディスク、CD-ROM、DVD-ROM、半導体メモリなどである。
各種機能を実現するための一連の処理は、一例として、プログラムの形式で二次記憶装置に記憶されており、このプログラムをCPUが主記憶装置に読み出して、情報の加工・演算処理を実行することにより、各種機能が実現される。なお、プログラムは、二次記憶装置に予めインストールしておく形態や、コンピュータ読み取り可能な記憶媒体に記憶された状態で提供される形態、有線又は無線による通信手段を介して配信される形態等が適用されてもよい。コンピュータ読み取り可能な記憶媒体とは、磁気ディスク、光磁気ディスク、CD-ROM、DVD-ROM、半導体メモリ等である。
まず、内気モードにおける空気の流れ等について説明する。
筐体11内に吸入された内気は、筐体11内を上方から下方へ流通する。その際に、フィルタ31を通過する。この時、内気の主流は、圧力損失が少ないルートを流通するため、フィルタ31のうち、所定の領域Aを通過する。フィルタ31を通過する際に、内気中を浮遊する粒子等がフィルタ31に捕捉される。フィルタ31の所定の領域Aは、多くの内気が通過することから他の領域よりも多くの粒子等が捕捉される。
フィルタ31を通過して清浄化された内気はファン吸い込み口44から筐体11の外部へ排出され、ダクト(図示省略)等を介してHVACユニットに供給され、HVACユニットで温度が調整される。温度が調整された内気は、車室内に吹出される。
また、第2紫外線照射装置28は、図2の矢印U2に示すように、紫外線を反射板29cに向かって照射する。反射板29cで反射した紫外線の一部は、矢印U3で示すように、フィルタ31の所定の領域Aに向かって照射される。これにより、フィルタ31(特に所定の領域A)に捕捉された粒子等に付着したウイルス等を不活化する。
まず、外気モードにおける空気の流れ等について説明する。
筐体11内に吸入された外気の流れは、筐体11内の内気の流れと同じであるので、詳細な説明は省略する。
本実施形態では、第1紫外線照射装置27及び第2紫外線照射装置28がフィルタ31に対して紫外線を照射している。これにより、フィルタ31で捕捉した浮遊物に付着している微生物やウイルス等を不活化することができる。
本実施形態では、制御部が、インテークダンパ29が内気吸入口23を開放している状態において紫外線を照射するように第1紫外線照射装置27及び第2紫外線照射装置28を制御している。これにより、空気が汚染され易い内気を循環させる場合において、フィルタ31で捕捉した浮遊物に付着しているウイルス等を不活化することができる。したがって、車室内に吹出される空気を清浄化することができる。
一方で、本実施形態では、反射板29cが、インテークダンパ29が外気吸入口24を閉鎖している状態において、フィルタ31と対向するように設けられている。これにより、反射板29cは、第2紫外線照射装置28から照射された紫外線をフィルタ31へ反射することができる。反射板29cが反射した紫外線は、フィルタ31のうち、反射板29cからの距離が近い外気吸入口24側の領域には強く照射される。一方で、フィルタ31のうち、反射板29cからの距離が比較的遠い内気吸入口23側の領域には弱く照射される。
このように、フィルタ31のうち内気吸入口23側の領域には、第1紫外線照射装置27及び第2紫外線照射装置28からの紫外線が強く照射されるものの、反射板29cが反射する第1紫外線照射装置27及び第2紫外線照射装置28からの紫外線は弱く照射される。一方で、フィルタ31のうち外気吸入口24側の領域には、第1紫外線照射装置27及び第2紫外線照射装置28からの紫外線が弱く照射されるものの、反射板29cが反射する第1紫外線照射装置27及び第2紫外線照射装置28からの紫外線は強く照射される。したがって、フィルタ31に照射される紫外線の強さのばらつきを低減することができる。
次に、上記実施形態の変形例について図4を用いて説明する。
本変形例では、インテークダンパの閉鎖部の形状及び反射板の形状が上記実施形態と異なっている。その他の点は上記実施形態と同様であるので、同様の構成について同一の符号を付してその詳細な説明は省略する。
なお、閉鎖部59bの中心領域以外(凹部59d以外)の領域は、平板状とされている。このようにすることで、内気吸入口23及び外気吸入口24を閉鎖する際に、各開口の縁と面接触することができるので、効果的に内気吸入口23及び外気吸入口24を閉鎖することができる。
本変形例では、反射板59cが、反射する紫外線がフィルタ31に集約するように凹んでいる。これにより、より多くの紫外線をフィルタ31に照射することができるので、より好適に、フィルタ31で捕捉した浮遊物に付着しているウイルス等を不活化することができる。したがって、車室内に吹出される空気を清浄化することができる。
例えば、上記実施形態では、第1紫外線照射装置27及び第2紫外線照射装置28の2つを設ける例について説明したが、本開示はこれに限定されない。第1紫外線照射装置27または第2紫外線照射装置28のどちらか一方のみを設けてもよい。また、第1紫外線照射装置27を複数設けてもよく、また、第2紫外線照射装置28を複数設けてもよい。
本開示の第1態様に係る送風装置は、車両外部の空気である外気又は車室内の空気である内気の温度を調整し前記車室内に吹出す温度調整装置に対して、外気又は内気を供給する送風装置(10)であって、外殻を為す筐体(11)と、前記筐体に設けられ、前記筐体の内部に内気を吸入する内気吸入口(23)と、前記筐体に設けられ、前記筐体の内部に外気を吸入する外気吸入口(24)と、前記内気吸入口又は前記外気吸入口を選択的に閉鎖するインテークダンパ(29)と、前記筐体の内部に設けられ、前記筐体の内部に吸入した空気中を浮遊する浮遊物を捕捉する捕捉部(31)と、前記捕捉部に対して紫外線を照射する第1紫外線照射部(27)と、前記筐体に固定され、前記内気吸入口を覆うように設けられ、前記第1紫外線照射部が取り付けられる取付部(26)と、を備え、前記第1紫外線照射部は、前記内気吸入口を平面視した際に、前記内気吸入口と重複するように設けられている。
上記構成では、制御部が、インテークダンパが内気吸入口を開放している状態において紫外線を照射するように第1紫外線照射部を制御している。これにより、空気が汚染され易い内気を循環させる場合において、捕捉部で捕捉した浮遊物に付着しているウイルス等を不活化することができる。したがって、車室内に吹出される空気を清浄化することができる。
一方で、上記構成では、反射部が、インテークダンパが外気吸入口を閉鎖している状態において、捕捉部と対向するように設けられている。これにより、反射部は、第2紫外線照射部から照射された紫外線を捕捉部へ反射することができる。反射部が反射した紫外線は、捕捉部のうち、反射部からの距離が近い外気吸入口側の領域には強く照射される。一方で、捕捉部のうち、反射部からの距離が比較的遠い内気吸入口側の領域には弱く照射される。
このように、捕捉部のうち内気吸入口側の領域には、第1紫外線照射部からの紫外線が強く照射されるものの、反射部が反射する第2紫外線照射部からの紫外線は弱く照射される。一方で、捕捉部のうち外気吸入口側の領域には、第1紫外線照射部からの紫外線が弱く照射されるものの、反射部が反射する第2紫外線照射部からの紫外線は強く照射される。したがって、捕捉部に照射される紫外線の強さのばらつきを低減することができる。
