Description

【０００１】
【発明の属する技術分野】
本発明は、水分の吸着と放出とが可能な回転式素子を用いた加湿装置、及び加湿装置を用いた空気調和機に関する。
【０００２】
【従来の技術】
従来の加湿装置としては、例えば特開平１１−２４１８３８号公報、特開平１１−２４１８３９号公報に提案されているものがある。この構成では、回転式素子は、通過空気の水分を吸着する吸着部分と、通過空気に熱を与える熱回収部分と、この熱回収部分を通過した空気に水分を与える加湿部分とに区画されて用いられる。
【０００３】
この構成において、吸着部分の上流側に設けた第１の送風ファンで、吸着部分に外気を通過させて、外気の水分が吸着部に吸着される。一方、熱回収部分の上流側に設けた第２の送風ファンで熱回収部分に室内空気を通過させ、これを電気ヒータで加熱して高温空気とする。この高温空気は、加湿部を通過して水分が供給され、加湿空気になった後、室内へ給気され、室内が加湿されることになる。
【０００４】
【発明が解決しようとする課題】
しかしながら、前記のような従来の構成では、加湿運転停止時に通路内に水分が残ってしまうため、衛生面での問題があった。また、これらの加湿を空気調和機に用いた場合、加湿空気が室内に十分に攪拌されないと、室内全体に亘り十分な加湿性能が得られないという問題があった。
【０００５】
本発明は前記のような従来の問題を解決するものであり、衛生面の改善を図る機能を追加したり、加湿能力を向上せて加湿性能を向上させた加湿装置及びこれを用いた空気調和機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】
前記目的を達成するために、本発明の第１の加湿装置は、水分の吸着と放出とが可能な回転素子と、吸引した室外空気を、前記回転素子を介して室外に導く第１の通路と、前記室外空気の吸引を行う第１の送風手段と、吸引した室内空気を、前記回転素子を介して室内に導く第２の通路と、前記室内空気の吸引を行う第２の送風手段と、前記第２の通路に設けられた加熱手段とを備え、
前記回転素子は、前記第１の通路からの室外空気の水分を吸着する吸着部と、前記第２の通路からの前記加熱手段で加熱された室外空気に水分を放出する加湿部とに区画され、前記加湿部を経た加湿空気を室内に排気する加湿装置であって、
前記加湿装置の運転を制御する制御手段をさらに備え、前記制御手段は、前記加湿装置の運転停止の際は、前記回転素子の回転駆動を停止させ、前記加熱手段、及び前記第２の送風機の運転は停止させることなく、一定時間これらの運転を継続した後、これらの運転を停止する設定を含んでいることを特徴とする。
【０００７】
本発明の第２の加湿装置は、水分の吸着と放出とが可能な回転素子と、吸引した室外空気を、前記回転素子を介して室外に導く第１の通路と、前記室外空気の吸引を行う第１の送風手段と、吸引した室内空気を、前記回転素子を介して室内に導く第２の通路と、前記室内空気の吸引を行う第２の送風手段と、前記第２の通路に設けられた加熱手段とを備え、
前記回転素子は、前記第１の通路からの室外空気の水分を吸着する吸着部と、前記第２の通路からの前記加熱手段で加熱された室外空気に水分を放出する加湿部とに区画され、前記加湿部を経た加湿空気を室内に排気する加湿装置であって、
前記第１の通路の風量は、前記第２の通路の風量の５〜１５倍の範囲内であることを特徴とする。
【０００８】
次に、本発明の第１の空気調和機は、吸い込み口から吸引した空気を加湿させ、この加湿空気を吹き出し口から室内に供給する加湿装置を備えた空気調和機であって、
前記吹き出し口は、吹き出された加湿空気が、前記空気調和機の室内機の吹き出し空気と混合するように配置されており、
前記吸い込み口は、前記吹き出し口から吹き出された加湿空気を直接吸い込まない位置に配置されていることを特徴とする。
【０００９】
本発明の第２の空気調和機は、吸い込み口から吸引した空気を加湿させ、この加湿空気を吹き出し口から室内に供給する加湿装置を備えた空気調和機であって、
前記空気調和機の室内機は、前記室内機からの吹き出し空気の風向を上下方向に調節する第１の風向変更板と、左右方向に調節する第２の風向変更とを備え、前記吹き出し口は、吹き出された加湿空気が、前記空気調和機の室内機の吹き出し空気と混合するように配置されており、
前記第１の風向変更板の角度を空気が上向きに送風される角度とし、かつ前記第２の風向変更板の角度を空気が左右に広がって送風される角度とする設定が可能であることを特徴とする。
【００１０】
【発明の実施の形態】
本発明の加湿装置は、加湿装置の運転停止の際は、回転素子の回転駆動を停止させ、室内空気用の加熱手段、及び送風機の運転は停止させることなく、一定時間これらの運転を継続した後、これらの運転を停止する設定を含んでいることにより、加湿装置内での菌の繁殖を抑えることができ、菌の室内への放出も防止できる。
【００１１】
また、室外空気の通路の風量を、室内空気の通路の風量の５〜１５倍の範囲内としたことにより、最適な条件で加湿能力を発揮でき、無駄なエネルギーを省くことができる。
【００１２】
また、加熱手段の入力値と室内が目標湿度に到達するまでの時間から、室内を設定湿度に維持するのに必要な入力値を算出し、設定湿度到達時にはその入力値で加湿装置を運転することにより、必要最小限の消費電力で室内の湿度を安定して保つことができる。
【００１３】
本発明の加湿装置においては、前記第２の通路は、前記回転式素子を通過した室内空気を再び前記回転式素子に供給する中間通路をさらに備え、前記加熱手段は前記中間通路に設けられており、
前記回転式素子は、前記第１の通路に対応する吸着部と、前記第２の通路のうち、室内空気を最初に前記回転式素子に供給する部分に対応する熱回収部と、前記中間通路のうち、前記加熱手段で加熱した前記室内空気を再び前記回転式素子に供給する部分に対応する加湿部とに区画されていることが好ましい。この構成によれば、回転式素子に、熱回収部を設けたことにより、吸着部には熱回収部において事前に冷却された部分が回転移動してくるので、吸着部を通過する空気の水分の吸着能力を高めることができる。
【００１４】
本発明の空気調和機は、加湿空気と室内機の吹き出し空気とが混合するように配置され、加湿空気の吸い込み口は、吹き出し口から吹き出された加湿空気を直接吸い込まない位置に配置されていることにより、室内の湿度を速やかに所定の湿度に到達させることができる。
【００１５】
この構成において、前記吹き出し口は、前記空気調和機の室内機の前面側に配置されており、前記吸い込み口は前記室内機の背面に配置されていることが好ましい。このことは、吹き出し口から吹き出された加湿空気が、直接加湿空気の吸い込み口に吸い込まれることの防止に有効である。
【００１６】
また、本発明の空気調和機は、風向を上下方向に調節する第１の風向変更板と、左右方向に調節する第２の風向変更とを備え、第１の風向変更板の角度を空気が上向きに送風される角度とし、かつ第２の風向変更板の角度を空気が左右に広がって送風される角度とする設定が可能であることにより、室内全体を速やかに所定の湿度に到達させることができる。
【００１７】
以下、本発明の一実施形態について図面を参照しながら説明する。
【００１８】
（実施の形態１）
図１は、実施形態１に係る加湿装置の概略構成図を示している。加湿装置１内には、回転素子４が組み込まれている。回転素子４は、セラミックスのハニカム成型体に水分の吸着、脱離が可能な吸着剤を担持して得られる。例えば吸着剤にシリカゲルやゼオライト等を用いれば、低温（室温）でに水分を吸着し、約６０℃以上の高温で水分を脱離させることができる。
【００１９】
回転素子４は円筒形状であり、その大きさは例えば直径２００〜３００ｍｍ、厚さ３０ｍｍであり、２〜３ｒｐｍで回転するように制御される。回転素子４の、水分の吸着及び放出ができる性質を利用して、回転素子４は吸着部５と加湿部６とに区画されて使用される。吸着部５と加湿部６との比率は、例えば３：１が適当である。
【００２０】
吸着部５は、空気から水分を吸着する部分である。装置外から取り込まれた低温空気は、吸着部分２を通過すると、その空気に含まれる水分は、吸着部５に吸着されて取り除かれる。
【００２１】
加湿部６は、空気に水分を与える部分である。加湿部６に、加熱処理して温度上昇した空気を通過させると、その空気に水分が与えられ湿潤化を図ることができる。この場合、加湿部６は水分を吸着する機能が回復することになる。
【００２２】
なお、吸着部５と加湿部６の位置は固定されているが、回転素子４の回転に伴って、吸着部５、加湿部６に対応する回転素子４の部分が変化する。例えば、図１の状態において、吸着部５と対応している回転素子４の部分は、矢印Ｘ方向に回転が進行すると、順次、加湿部６に対応する部分に移動し、加湿部６に対応している回転素子４の部分は、矢印Ｘ方向に回転が進行すると、順次、吸着部５に対応する部分に移動することになる。
【００２３】
加湿装置１には、吸引した室外空気Ａを、回転素子４の吸着部５を経て室外へ排気させる通路７が配設されている。以下、加湿装置が室内に加湿空気を供給する運転をしている状態において、通路内を空気が始点ａから終点ｂへと進行しているとすると、始点ａ側を上流側といい、終点ｂ側を下流側という。
【００２４】
通路７のうち、回転素子４に対して上流側に、送風手段であるファン８が設けられている。ファン８の送風作用により、室外空気Ａは通路７内に吸引され、回転素子４の吸着部５を経て室外へ排気される。この場合、室外空気Ａは、吸着部５において、水分が吸着され乾燥した状態で排気されることになる。
【００２５】
また、加湿装置１内には、吸引した室内空気Ｂを回転素子４の加湿部６を経て室内へ排気させる通路２が配設されている。通路２のうち、回転素子４に対して下流側に、送風手段であるファン３が設けられている。ファン３の送風作用によって、室内空気Ｂは、通路２内に吸引される。
【００２６】
通路７内の空気は、加熱手段であるヒータ９で加熱され、この加熱された高温空気は加湿部６に至る。ヒータ９は、ニクロムヒータやセラミックヒータを用いることができる。加湿部６には、回転素子４のうち吸着部５において水分を吸着した部分が回転移動してくるので、加湿部６において、高温空気に水分が与えられ、加湿処理された湿潤空気が室内に排気され、室内が加湿されることになる。
また、高温空気に水分を与えることにより、回転素子４は、水分吸着性の回復が図られ、吸着部５に回転移動し、再び水分を吸着することになる。
【００２７】
ここで、前記のように通路７の回転素子４に対して上流側は、湿潤空気が流動するので、加湿装置１の作動時間の経過に伴い通路内は多湿状態になる。この状態で加湿装置の運転を停止させると、通路内には結露する部分も発生する。このため、室内から導入される菌が繁殖する可能性もあり、衛生面の対策が必要となる。
【００２８】
本実施形態は制御手段（図示せず）を備えており、この制御手段により、回転素子４、ヒータ９、及び送風機３、８の通電の入切を制御できる。この制御手段は、加湿空気の室内供給を停止した場合は、回転素子４の回転駆動は停止させるが、ヒータ９の加熱、送風機２の回転は停止させることなく、そのまま一定時間これらの通電を継続した後、これらの通電を停止するという設定を備えている。
【００２９】
このことにより、加湿空気の室内供給を停止した場合は、ヒータ９で加熱された空気が一定時間、通路７内を流動し室内へ排気されるので、通路７内を乾燥させることができる。この場合、回転素子４は停止しているので、水分を含んだ部分が順次回転移動してくることはなく、一定時間経過すれば加湿部６も乾燥し、加湿空気が通路６の上流側に供給されることもない。
【００３０】
なお、加湿空気の室内供給の停止は、人の操作により停止した場合だけでなく、タイマ等で自動的に停止した場合も含む。
【００３１】
図１に示した構成の加湿装置１を用いて、通路７から放出された菌数を測定し、効果を検証した。実験に用いた加湿装置１の回転素子４は、直径３００ｍｍ、厚さ３０ｍｍの回転素子にシリカゲルを担持したものを用い、ヒータ９にはニクロムヒータを用い、入力は５００Ｗとした。また、通路２（室外空気用）の風量は５ｍ３／ｍｉｎ、通路７（室外空気用）の風量は０．５ｍ３／ｍｉｎと設定した。
【００３２】
実験には、２台の加湿装置を用い、本実施形態に係る加湿装置（加湿装置Ａ）は、加湿運転終了後、回転素子を停止した状態で、経路内の乾燥運転（ヒータ９及び送風機２を運転）を３０分行う設定とし、比較例に係る加湿装置（加湿装置Ｂ）は、加湿運転終了と同時に、経路内の送風も停止させる設定とした。
【００３３】
加湿装置Ａ及びＢを並べて設置し、人の居住する室内（３０ｍ３）の外壁に設置し、２４時間運転した後、加湿運転を停止させた。その後、本実施形態に係る加湿装置Ａは、設定の通り回転素子を停止した状態で、経路内の乾燥運転を３０分行った。この後、加湿装置Ａは２４時間放置した。
【００３４】
一方、比較例に係る加湿装置Ｂは、加湿運転を停止後、２４時間放置した。この場合、加湿装置Ｂは加湿運転を停止後は、経路内の送風も停止していることになる。
【００３５】
実験開始から２４時間の放置が完了するまでの間、室外は気温２〜８℃、湿度４０〜５０％であった。２４時間の放置後、再度加湿装置Ａ及びＢを運転し、
通路７の吹き出し口から吹き出される空気を、寒天培地を入れたシャーレに１０分間あてた。このシャーレを３７℃で１８時間保存し、シャーレに繁殖した大腸菌等と思われる菌のコロニー数を数えた。その結果、加湿装置Ａの場合は、コロニーが１個であったのに対して、加湿装置ｂの場合は、コロニーが３２個であり、明らかな差が確認された。
【００３６】
（実施の形態２）
図１に示したような加湿装置１において、通路２に設けた室外空気用の送風機３と、通路７に設けた室内空気用の送風機８との風量比と加湿能力との関係について実験確認を行った。
【００３７】
実験に用いた加湿装置１は、図１の構成であり、回転素子４として、直径３００ｍｍ、厚さ２０ｍｍのセラミックスのハニカム成型体にシリカゲルを担持したものを用い、ヒータ９としてニクロムヒータを用いた。
【００３８】
実験は、室外空気用の通路２と、室内空気用の通路７の風量をそれぞれ変化させて加湿量の変化を測定した。加湿量は通路７の吹出し口から出る空気の温度と露点（絶対湿度）と風量とから算出した。
【００３９】
以下の表１にサンプルのＮｏ．１〜１６の測定結果を、表２にサンプルのＮｏ．１７〜３２の測定結果を、表３にサンプルのＮｏ．３３〜４８の測定結果を示す。表１〜３中、Ａは通路２（室外空気用）の風量、Ｂは通路７（室内空気用）の風量を示している。
【００４０】

【００４１】
【表２】
Figure 2004020109
【００４２】
【表３】
Figure 2004020109
【００４３】
表１の結果をみると、Ａ／Ｂの値が５〜１５の範囲内において、十分な加湿量を維持しつつ安定しており、この範囲から外れると加湿量は低下しその低下率も大きくなっている。このことは、表２、３の結果についても同様である。
【００４４】
これらの結果より、室外空気用の通路の風量を、室内空気用の通路の風量に対して５〜１５倍の範囲内に設定すれば、十分な加湿能力を発揮でき、無駄なエネルギーを省くことにもなる。
【００４５】
なお、回転素子４の直径を２００ｍｍｍ、４００ｍｍ、５００ｍｍとした場合でも同様の傾向の結果が得られ、ヒータ入力を２００Ｗから５００Ｗまで変化させた場合でも同様の傾向の結果が得られた。また、吸着剤をゼオライトにした場合も同様であった。
【００４６】
（実施の形態３）
図２（ａ）は、実施形態３に係る空気調和機の要部断面図である。本図に示した空気調和機は、室内送風機と室内熱交換器とを含む室内機と、室外送風機と室外熱交換器とを含む室外機とを備え、冷房、暖房、及び除湿等の機能を有するヒートポンプ式空気調和機の例であり、本図は室内機を図示している。
【００４７】
室内機本体１０内には、熱交換器１１、及びクロスローファン（以下、「ファン」という。）１２が設けられており、室内機本体１０の下部には、ファン１２で送風される空気の向きを調節する風向変更板１３が設けられている。
【００４８】
室内機本体１０内には、図１に示した構成の加湿装置１の通路７が取り付けられており、室内機本体１０の背面上部に通路７の吸い込み口７ｂが配置されており、風向変更板１３の後方（室内機本体１０の背面側）に通路７の吹き出し口７ａが配置されている。この構成によれば、吹き出し口７ａから吹き出される空気と、ファン１２で送風される空気とを混合して風向変更板１３を経て室内に吹き出すことができる。さらに、吹き出し口７ａから吹き出された空気が、吸い込み口７ｂに直接吸い込まれることを防止できる。
【００４９】
図２（ｂ）は、比較例に係る空気調和機の要部断面図である。図２（ａ）の構成が、通路７の吸い込み口７ｂが室内機本体１０の背面上部に配置されているのに対して、図２（ｂ）の構成は、吸い込み口７ｂは室内機本体１０の下部のうち、吸い込み口７ｂの近傍に配置されている。
【００５０】
これらの本実施形態に係る空気調和機、及び比較例に係る空気調和機を用いて比較実験を行った。設置条件は、図３に示した通りであり、空気調和機の室内機本体１０を室内側壁上部に、加湿装置１を室外側壁上部に、空気調和機の室外機を室外側壁下部にそれぞれ配置した。室内機本体１０と室外機１４とは冷媒配管（図示せず）によって連結されている。また、室外環境を５℃、５０％とし、空気調和機の室温設定は２５℃とした。
【００５１】
比較実験によって、図３の測定点Ｘ（室内中央）の相対湿度５０％に到達する時間を測定し比較した。その結果、本実施形態に係る空気調和機が３５分に対して、比較例に係る空気調和機は６２分であった。このように、比較例に係る空気調和機の到達時間が遅いのは、本実施形態に係る空気調和機では、吹出し口７ａから吹き出された加湿空気の大半は室内へ吹き出されるのに対して、比較例に係る空気調和機では、吹出し口７ａから吹き出された加湿空気の相当量が室内へ吹き出される前に吸い込み口７ｂ吸い込まれるためと考えられる。
【００５２】
（実施の形態４）
図４は、実施形態４に係る空気調和機の要部断面図であり、本図は室内機を図示している。室内機本体１０内には、熱交換器１１、及びファン１２が設けられており、室内機本体１０の下部には、ファン１２で送風される空気の向きを調節する風向変更板１３、及び風向変更板１６が設けられている。風向変更板１３が上下方向の風向を調節するものであるのに対して、風向変更板１６は左右方向の風向を調節するものである。
【００５３】
風向変更板１６の後方（室内機本体１０の背面側）に通路７の吹き出し口７ａが配置されている。また、通路７の吸い込み口７ｂが、吹き出し口７ａの近傍に配置されている。
【００５４】
このような室内機本体１０において、風向変更板１３及び風向変更板１６の角度設定を２種類として比較実験を行った。第１の設定は、風向変更板１３の角度を空気が上向きに送風される角度とし、かつ風向変更板１６の角度を空気が左右に広がって送風される角度とする設定である。第２の設定は、風向変更板１３の角度を空気が下向きに送風される角度とし、かつ風向変更板１６の角度を空気が左右に広がらずに送風される角度とする設定である。、
第１の設定、及び第２の設定において、図３のＺ点（室内機１０から離れたコーナ部）において相対湿度が５０％に到達する時間Ｔを比較した。第１の設定では時間Ｔが４６分であるのに対して、第２の設定では時間Ｔが７５分であり、第１の設定の加湿能力が優れていることが分った。これは、第１の設定では、加湿空気が室内全体に攪拌されるためと考えられ、第１の設定によれば、部屋の端部の湿度も速やかに上昇させることが可能となる。
【００５５】
なお、通路７の吸い込み口７ｂが、吹き出し口７ａの近傍に配置されている例で説明したが、図２（ａ）の例のように、吸い込み口７ｂを室内機本体１０の背面上部に配置してもよい。
【００５６】
また、空気を循環させず、外気を加湿空気として室内導入する構成の加湿機能付空気調和機においても同様の結果が得られた。
【００５７】
（実施の形態５）
図５は、実施形態５に係る加湿装置の概略構成図を示している。回転素子４は、吸着部５、加湿部６、及び熱回収部１５に区画されて使用される。熱回収部１５は、温度の低い空気を通過させて、回転素子４の温度を下げるとともに、通過空気の温度を高める部分である。
【００５８】
また、本実施形態では、室内空気Ａが吸引されている場合において、通路７のうち、回転素子４（熱回収部１５）へ最初に室内空気を導く供給通路７ａと、回転素子４（加湿部６）を通過した室内空気を室内へ排気する排気通路７ｂとの間に、中間通路７ｃが配置されている。ヒータ９は、この中間通路７ｃに設けられている。
【００５９】
熱回収部１５には供給通路７ａからの室内空気が取り込まれる。加湿部６は、ヒータ９で加熱された温度の高い空気が通過するので、加湿部６の温度が上昇する。熱回収部１５には、室温である室内空気Ａが取り込まれるので、回転により加湿部６に対応する部分が熱回収部１５に移動すると、熱回収部１５における回転素子４は冷却されることになる。この場合、熱回収部１５を通過した空気は温度上昇することになる。この構成によれば、吸着部５へは、熱回収部１５において事前に冷却された部分が回転移動してくるので、吸着部５を通過する空気の水分の吸着能力を高めることができる。
【００６０】
本図に示した加湿装置１ａにおいても、加湿処理された湿潤空気が、通路７ｂを経て室内に排気され、室内が加湿されることは、図１に示した加湿装置１と同様であり、前記各実施形態と組み合わせて用いることができる。
【００６１】
【発明の効果】
以上のように、本発明の加湿装置によれば、加湿装置の運転停止の際は、回転素子の回転駆動を停止させ、室内空気用の加熱手段、及び送風機の運転は停止させることなく、一定時間これらの運転を継続した後、これらの運転を停止する設定を含んでいることにより、加湿装置内での菌の繁殖を抑えることができ、菌の室内への放出も防止できる。
【００６２】
また、本発明の空気調和機によれば、加湿空気と室内機の吹き出し空気とが混合するように配置され、加湿空気の吸い込み口は、吹き出し口から吹き出された加湿空気を直接吸い込まない位置に配置されていることにより、室内の湿度を速やかに所定の湿度に到達させることができる。

[0017]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0018]
(Embodiment 1)
FIG. 1 is a schematic configuration diagram of the humidifier according to the first embodiment. The rotating element 4 is incorporated in the humidifier 1. The rotating element 4 is obtained by supporting an adsorbent capable of adsorbing and releasing moisture on a ceramic honeycomb molded body. For example, if silica gel or zeolite is used as the adsorbent, water can be adsorbed at a low temperature (room temperature) and desorbed at a high temperature of about 60 ° C. or higher.
[0019]
The rotating element 4 has a cylindrical shape, and has a size of, for example, a diameter of 200 to 300 mm and a thickness of 30 mm, and is controlled to rotate at 2 to 3 rpm. Utilizing the property of the rotating element 4 that can adsorb and release moisture, the rotating element 4 is used by being divided into an adsorbing section 5 and a humidifying section 6. An appropriate ratio of the adsorbing section 5 to the humidifying section 6 is, for example, 3: 1.
[0020]
The adsorption unit 5 is a part that adsorbs moisture from air. When the low-temperature air taken in from the outside of the apparatus passes through the adsorption part 2, the water contained in the air is adsorbed by the adsorption part 5 and removed.
[0021]
The humidifying section 6 is a section that gives moisture to air. When the air whose temperature has been increased by the heat treatment is passed through the humidifying section 6, moisture is given to the air, so that the air can be moistened. In this case, the function of the humidifying unit 6 to adsorb moisture is restored.
[0022]
Although the positions of the suction unit 5 and the humidifying unit 6 are fixed, the portion of the rotary element 4 corresponding to the suction unit 5 and the humidifying unit 6 changes as the rotating element 4 rotates. For example, in the state of FIG. 1, the portion of the rotary element 4 corresponding to the suction unit 5 sequentially moves to a portion corresponding to the humidifying unit 6 as the rotation proceeds in the arrow X direction, and When the rotation of the rotating element 4 proceeds in the direction of the arrow X, the rotating element 4 sequentially moves to a part corresponding to the suction unit 5.
[0023]
The humidifier 1 is provided with a passage 7 for exhausting the sucked outdoor air A to the outside through the suction section 5 of the rotary element 4. Hereinafter, in a state where the humidifying device is operating to supply humidified air into the room, assuming that air is traveling from the start point a to the end point b in the passage, the start point a side is referred to as the upstream side, and the end point b The side is called the downstream side.
[0024]
In the passage 7, a fan 8 serving as a blower is provided on the upstream side of the rotary element 4. By the blowing action of the fan 8, the outdoor air A is sucked into the passage 7, and is exhausted to the outside through the suction part 5 of the rotating element 4. In this case, the outdoor air A is exhausted in the adsorption section 5 in a state where moisture is adsorbed and dried.
[0025]
In addition, a passage 2 for exhausting the sucked room air B into the room through the humidifying section 6 of the rotating element 4 is provided in the humidifying device 1. In the passage 2, a fan 3 as a blower is provided downstream of the rotary element 4. The indoor air B is sucked into the passage 2 by the blowing action of the fan 3.
[0026]
The air in the passage 7 is heated by a heater 9 as heating means, and the heated high-temperature air reaches the humidifying section 6. As the heater 9, a nichrome heater or a ceramic heater can be used. Since the portion of the rotary element 4 to which the moisture has been adsorbed by the adsorbing portion 5 rotates, the humidifying portion 6 is provided with moisture to the high-temperature air, and the humidified humidified air enters the room. The air is exhausted and the room is humidified.
In addition, by applying moisture to the high-temperature air, the rotating element 4 recovers the moisture adsorbing property, rotates and moves to the adsorbing section 5, and adsorbs moisture again.
[0027]
Here, as described above, the humid air flows on the upstream side of the rotary element 4 of the passage 7, so that the inside of the passage becomes humid as the operation time of the humidifier 1 elapses. When the operation of the humidifying device is stopped in this state, a portion where dew condensation occurs also occurs in the passage. For this reason, there is a possibility that bacteria introduced from the room may propagate, and it is necessary to take measures for hygiene.
[0028]
The present embodiment includes a control unit (not shown), and the control unit can control the turning on and off of the rotation element 4, the heater 9, and the blowers 3 and 8. When the indoor supply of the humidified air is stopped, the control means stops the rotation drive of the rotary element 4 but continues the energization of the heater 9 and the blower 2 for a certain period of time without stopping the rotation of the blower 2. After that, the setting to stop the energization is provided.
[0029]
Thus, when the supply of the humidified air to the room is stopped, the air heated by the heater 9 flows through the passage 7 for a certain time and is exhausted into the room, so that the inside of the passage 7 can be dried. In this case, since the rotating element 4 is stopped, the portion containing moisture does not sequentially rotate and move, and after a certain period of time, the humidifying section 6 also dries, and the humidified air is supplied to the upstream side of the passage 6. There is no supply.
[0030]
The stop of the indoor supply of the humidified air includes not only a case where the supply is stopped by a human operation but also a case where the supply is automatically stopped by a timer or the like.
[0031]
Using the humidifier 1 having the configuration shown in FIG. 1, the number of bacteria released from the passage 7 was measured, and the effect was verified. The rotating element 4 of the humidifier 1 used in the experiment used a rotating element having a diameter of 300 mm and a thickness of 30 mm carrying silica gel, a nichrome heater was used as the heater 9, and the input was 500 W. In addition, the air volume of passage 2 (for outdoor air) was set to 5 m 3 / min, and the air volume of passage 7 (for outdoor air) was set to 0.5 m 3 / min.
[0032]
In the experiment, two humidifiers were used, and the humidifier (humidifier A) according to the present embodiment, after the humidification operation was completed, the rotary operation was stopped and the drying operation (heater 9 and blower 2 Is operated for 30 minutes, and the humidifying device (humidifying device B) according to the comparative example is set to stop blowing air in the path at the same time as the end of the humidifying operation.
[0033]
Humidifiers A and B were placed side by side, placed on the outer wall of a room (30 m 3 ) where people lived, and after 24 hours of operation, the humidification operation was stopped. Thereafter, the humidifying device A according to the present embodiment performed the drying operation in the path for 30 minutes with the rotating element stopped as set. Thereafter, the humidifier A was left for 24 hours.
[0034]
On the other hand, the humidification device B according to the comparative example was left for 24 hours after stopping the humidification operation. In this case, after the humidification device B stops the humidification operation, the air supply in the path is also stopped.
[0035]
From the start of the experiment to the completion of the standing for 24 hours, the outside temperature was 2 to 8 ° C and the humidity was 40 to 50%. After standing for 24 hours, the humidifiers A and B are operated again,
The air blown from the outlet of the passage 7 was applied to a petri dish containing an agar medium for 10 minutes. This petri dish was stored at 37 ° C. for 18 hours, and the number of colonies of bacteria thought to be Escherichia coli and the like propagated in the petri dish was counted. As a result, in the case of the humidifier A, there was one colony, whereas in the case of the humidifier b, there were 32 colonies, and a clear difference was confirmed.
[0036]
(Embodiment 2)
In the humidifying device 1 as shown in FIG. 1, an experimental confirmation was made on the relationship between the air volume ratio of the outdoor air blower 3 provided in the passage 2 and the indoor air blower 8 provided in the passage 7 and the humidifying capacity. went.
[0037]
The humidifier 1 used in the experiment has the configuration shown in FIG. 1, and uses a ceramic honeycomb formed body having a diameter of 300 mm and a thickness of 20 mm carrying silica gel as the rotating element 4 and a nichrome heater as the heater 9. .
[0038]
In the experiment, the change of the humidification amount was measured by changing the air flow rate of the outdoor air passage 2 and the indoor air passage 7 respectively. The humidification amount was calculated from the temperature, dew point (absolute humidity), and air volume of the air coming out of the outlet of the passage 7.
[0039]
Table 1 below shows the sample Nos. Table 2 shows the measurement results of Sample Nos. 1 to 16 in Table 2. Table 3 shows the measurement results of Sample Nos. 17 to 32. 33 to 48 show measurement results. In Tables 1 to 3, A indicates the air volume of the passage 2 (for outdoor air), and B indicates the air volume of the passage 7 (for indoor air).

According to the results of Table 1, when the value of A / B is in the range of 5 to 15, the humidification amount is stable while maintaining a sufficient humidification amount. Has become. This is the same for the results in Tables 2 and 3.
[0044]
From these results, if the air flow rate of the outdoor air passage is set within a range of 5 to 15 times the air flow rate of the indoor air passage, sufficient humidifying capacity can be exhibited, and unnecessary energy can be saved. Also.
[0045]
Similar results were obtained when the diameter of the rotating element 4 was 200 mm, 400 mm, and 500 mm, and similar results were obtained when the heater input was changed from 200 W to 500 W. The same was true when zeolite was used as the adsorbent.
[0046]
(Embodiment 3)
FIG. 2A is a cross-sectional view of a main part of an air conditioner according to a third embodiment. The air conditioner shown in this figure includes an indoor unit including an indoor blower and an indoor heat exchanger, and an outdoor unit including an outdoor blower and an outdoor heat exchanger, and has functions such as cooling, heating, and dehumidification. This is an example of a heat pump type air conditioner having an indoor unit.
[0047]
A heat exchanger 11 and a cross low fan (hereinafter, referred to as “fan”) 12 are provided in the indoor unit main body 10, and the air blown by the fan 12 is provided below the indoor unit main body 10. A wind direction changing plate 13 for adjusting the direction is provided.
[0048]
A passage 7 of the humidifying device 1 having the configuration shown in FIG. 1 is attached inside the indoor unit main body 10, and a suction port 7 b of the passage 7 is arranged at an upper rear portion of the indoor unit main body 10. The outlet 7a of the passage 7 is disposed behind the rear side 13 (the rear side of the indoor unit main body 10). According to this configuration, the air blown out from the outlet 7a and the air blown by the fan 12 can be mixed and blown into the room via the wind direction change plate 13. Further, it is possible to prevent the air blown out from the outlet 7a from being directly sucked into the inlet 7b.
[0049]
FIG. 2B is a cross-sectional view of a main part of an air conditioner according to a comparative example. In the configuration of FIG. 2A, the suction port 7b of the passage 7 is disposed on the upper rear surface of the indoor unit main body 10, whereas in the configuration of FIG. Is located in the vicinity of the suction port 7b in the lower part.
[0050]
A comparative experiment was performed using the air conditioner according to the present embodiment and the air conditioner according to the comparative example. The installation conditions are as shown in FIG. 3, in which the indoor unit main body 10 of the air conditioner is arranged at the upper part of the indoor side wall, the humidifier 1 is arranged at the upper part of the outdoor side wall, and the outdoor unit of the air conditioner is arranged at the lower part of the outdoor side wall. . The indoor unit main body 10 and the outdoor unit 14 are connected by a refrigerant pipe (not shown). The outdoor environment was set at 5 ° C. and 50%, and the room temperature of the air conditioner was set at 25 ° C.
[0051]
By a comparative experiment, the time required to reach a relative humidity of 50% at the measurement point X (center of the room) in FIG. 3 was measured and compared. As a result, the air conditioner according to the present embodiment took 35 minutes, whereas the air conditioner according to the comparative example took 62 minutes. Thus, the arrival time of the air conditioner according to the comparative example is slow because most of the humidified air blown out from the outlet 7a is blown indoors in the air conditioner according to the present embodiment. In the air conditioner according to the comparative example, it is considered that a considerable amount of the humidified air blown out from the outlet 7a is sucked into the inlet 7b before being blown into the room.
[0052]
(Embodiment 4)
FIG. 4 is a sectional view of a main part of an air conditioner according to Embodiment 4, and FIG. 4 illustrates an indoor unit. A heat exchanger 11 and a fan 12 are provided in the indoor unit main body 10, and a wind direction change plate 13 for adjusting the direction of air blown by the fan 12 and a wind direction are provided below the indoor unit main body 10. A change plate 16 is provided. The wind direction change plate 13 adjusts the wind direction in the vertical direction, while the wind direction change plate 16 adjusts the wind direction in the left and right direction.
[0053]
The outlet 7a of the passage 7 is disposed behind the wind direction changing plate 16 (on the rear side of the indoor unit main body 10). Further, the suction port 7b of the passage 7 is arranged near the blowout port 7a.
[0054]
In such an indoor unit main body 10, a comparison experiment was performed with two types of angle settings of the wind direction changing plate 13 and the wind direction changing plate 16. The first setting is a setting in which the angle of the wind direction change plate 13 is set to an angle at which air is blown upward, and the angle of the wind direction change plate 16 is set to an angle at which air spreads to the left and right. In the second setting, the angle of the wind direction changing plate 13 is set to an angle at which air is blown downward, and the angle of the wind direction changing plate 16 is set to an angle at which air is blown without spreading right and left. ,
In the first setting and the second setting, the time T at which the relative humidity reaches 50% at the point Z (the corner part distant from the indoor unit 10) in FIG. 3 was compared. While the time T was 46 minutes in the first setting, the time T was 75 minutes in the second setting, indicating that the humidifying ability of the first setting was excellent. This is considered to be because in the first setting, the humidified air is stirred in the entire room, and according to the first setting, the humidity at the end of the room can be quickly increased.
[0055]
Although the suction port 7b of the passage 7 has been described as being disposed in the vicinity of the outlet port 7a, the suction port 7b is disposed on the upper rear surface of the indoor unit main body 10 as in the example of FIG. May be.
[0056]
