Description

【０００１】
【発明の属する技術分野】
本発明は空気中の臭気や浮遊粉塵を除去すると共に、特に加湿機能を付加した空気清浄機に関するものである。
【０００２】
【従来の技術】
従来の空気清浄機は塵埃を帯電させて集塵板に捕集するものや、繊維状のフィルターに捕集するもの、また活性炭などを用いて空気中の臭気成分を除去するものがあるが、加湿機能付空気清浄機としては特開平４−４８９４６号公報に記載されているようなものが一般的であった。この加湿機能付空気清浄機は図１１と図１２に示すように空気清浄機１が空気清浄装置２と加湿器３との一体構成を成し、電気集塵手段４のイオナイザ部５の放電電極６と対向電極板７との間に直流高電圧を印加することにより放電電極６から対向電極板７に向かってコロナ放電が起こり、ダストなどの微粒子が荷電され、後流側のコレクタ部８の電極板９に捕集される。また、タンク１０から水槽１１に供給された水は超音波発振子１２により振動され、霧状の微粒子として水面から飛散し、加湿用水殺菌手段１３の送風機１４によって送り込まれたオゾンを含んだ清浄空気によって室内空気中に放出され、室内空気を加湿する。そして、タンク１０内で繁殖したバクテリアはタンク１０より水槽１１に入ってくるが、加湿用水殺菌手段１３の送風機１４によって送り込まれた清浄空気中のオゾンによって殺菌されるため、活性化した菌を室内空気中に放出することがないようになっていた。
【０００３】
【発明が解決しようとする課題】
しかしながら上記従来の構成ではコレクタ部８の交換や清掃が必要であり、そのメンテナンスが煩雑であること、そして集塵効果は有るが脱臭効果はほとんど無いという課題があった。またタンク１０内のバクテリアの繁殖は防ぐことができない為、衛生的に満足できるものではなかった。
【０００４】
一方脱臭効果を有する活性炭を搭載した空気清浄機もすべての悪臭成分に対しては十分機能しないため、酸性ガスやアルカリ性ガスに対応した添着活性炭を混合させるなどの方法が採られているが、いずれにせよ吸着容量が飽和すると交換しなければならず、メンテナンスの煩雑さとコストが高いという課題があった。
【０００５】
【課題を解決するための手段】
本発明は上記課題を解決するために、空気吸い込み口と、水中に設け、一方は直流電源のプラス側に接続した陽極及び他方は前記直流電源のマイナス側に接続した陰極からなる一対の電極と前記電極間に設け、水中のイオン性物質は自由に通過する隔膜を有する水槽と、前記空気吸い込み口に臨ませて前記水槽の上方に前記陽極側と前記陰極側とに分離し並設して、前記空気吸い込み口より吸引された空気を濾過し、かつ前記水槽の水で濡れた水分の一部が蒸発する濾過蒸発部と、前記水槽の前記陽極側の水と前記陰極側の水とを各々別個に前記濾過蒸発部の上部へ揚水する各々別個のポンプと、送風機と、空気吹き出し口とを備え、前記濾過蒸発部の前記陽極側と前記陰極側の上部に各々別個のノズルを設け、前記ノズルにより前記ポンプが揚水した水を前記濾過蒸発部の前記陽極側と前記陰極側の上部より散水するように構成した空気清浄機である。
【０００６】
上記発明によれば、濾過蒸発部は水槽の上方に陽極側と陰極側とに分離し、かつ空気吸い込み口に臨ませて並設し、水槽の陽極側の水と陰極側の水とを各々別個のポンプにより揚水し、濾過蒸発部の陽極側と陰極側との上部に各々別個のノズルにより散水するように構成しているので、濾過蒸発部は空気吸い込み口に臨ませた湿式フィルターとなり、通過する空気中の塵埃を捕捉し、悪臭成分も水の中に溶解吸収し空気を浄化するとともに、水分の一部が蒸発し空気を加湿する。また、水槽内の水は電気分解され、隔膜を挟んで酸性水とアルカリ性水が生成され、分離した一方の濾過蒸発部は酸性水を含み、他方の濾過蒸発部はアルカリ性水を含むことになり、酸性ガスはアルカリ性水に吸収されやすく、アルカリ性ガスは酸性水に吸収されやすいため、各種の悪臭成分を除去する性能が向上するとともに、濾過蒸発部からは水分の一部が蒸発し空気を加湿することができる。また、水槽内の水は酸性とアルカリ性に保持できるため水槽内でのバクテリアの繁殖を防ぐことができ、濾過蒸発部も酸性水あるいはアルカリ水を散水されるのでバクテリアの繁殖を防ぐことができる。
【０００７】
【発明の実施の形態】
上記課題を解決するため請求項１記載の発明は、空気吸い込み口と、水中に設け、一方は直流電源のプラス側に接続した陽極及び他方は前記直流電源のマイナス側に接続した陰極からなる一対の電極と前記電極間に設け、水中のイオン性物質は自由に通過する隔膜を有する水槽と、前記空気吸い込み口に臨ませて前記水槽の上方に前記陽極側と前記陰極側とに分離し並設して、前記空気吸い込み口より吸引された空気を濾過し、かつ前記水槽の水で濡れた水分の一部が蒸発する濾過蒸発部と、前記水槽の前記陽極側の水と前記陰極側の水とを各々別個に前記濾過蒸発部の上部へ揚水する各々別個のポンプと、送風機と、空気吹き出し口とを備え、前記濾過蒸発部の前記陽極側と前記陰極側の上部に各々別個のノズルを設け、前記ノズルにより前記ポンプが揚水した水を前記濾過蒸発部の前記陽極側と前記陰極側の上部より散水するように構成した空気清浄機である。
【０００８】
そして、濾過蒸発部は水槽の上方に陽極側と陰極側とに分離し、かつ空気吸い込み口に臨ませて並設し、水槽の陽極側の水と陰極側の水とを各々別個のポンプにより揚水し、濾過蒸発部の陽極側と陰極側との上部に各々別個のノズルにより散水する構成としているので、濾過蒸発部は空気吸い込み口に臨ませた湿式フィルターとなり、通過する空気中の塵埃を捕捉し、悪臭成分も水の中に溶解吸収し空気を浄化するが、水槽内の水は電気分解され、隔膜を挟んで酸性水とアルカリ性水が生成され、分離した一方の濾過蒸発部は酸性水を含み、他方の濾過蒸発部はアルカリ性水を含むことになり、酸性ガスはアルカリ性水に吸収されやすく、アルカリ性ガスは酸性水に吸収されやすいため、各種の悪臭成分を除去する性能が向上するとともに、濾過蒸発部からは水分の一部が蒸発し空気を加湿することができる。また、水槽内の水は酸性とアルカリ性に保持できるため水槽内でのバクテリアの繁殖を防ぐことができ、濾過蒸発部を酸性水あるいはアルカリ水を散水されるのでバクテリアの繁殖を防ぐことができる。
【０００９】
また、請求項２記載の発明は、空気吸い込み口と、水中に設け、一方は直流電源のプラス側に接続した陽極及び他方は前記直流電源のマイナス側に接続した陰極からなる一対の電極と前記電極間に設け、水中のイオン性物質は自由に通過する隔膜を有する水槽と、前記空気吸い込み口に臨ませて前記水槽の上方に前記陽極側と前記陰極側とに分離し並設して、前記空気吸い込み口より吸引された空気を濾過し、かつ前記水槽の水で濡れた水分の一部が蒸発する濾過蒸発部と、前記水槽の前記陽極側の水と前記陰極側の水とを各々別個に前記濾過蒸発部の上部へ揚水する各々別個のポンプと、送風機と、空気吹き出し口とを備え、前記濾過蒸発部の前記陽極側と前記陰極側の上部に、前記ポンプが揚水した水を前記濾過蒸発部の前記陽極側と前記陰極側の上部より散水する各々別個の複数の孔を有する散水ヘッダーを設け、前記濾過蒸発部は前記水槽の上方に前記陽極側と前記陰極側とに分離した２枚の布状フィルターで形成するとともに、前記布状フィルターは各々その上端で各々の前記散水ヘッダーを巻き包んで構成した空気清浄機である。
【００１０】
そして、濾過蒸発部である陽極側と陰極側との２枚の布状フィルターの上端で複数の孔を有する各々の散水ヘッダーを巻き込んだ構成となっているで、各々の散水ヘッダーからは空気中に酸性水とアルカリ性水を飛散させることなく、２枚の布状フィルターにしみ込ませて落水させる湿式フィルターの構成となるので、通過する空気中の塵埃を捕捉し、悪臭成分も水の中に溶解吸収して空気を浄化するとともに、空気吹き出し口から水を飛散させることなく水分の一部を蒸発させ空気の加湿を行うことができる。従って水槽内の水の損失を少なくし効率良い加湿を行うことができる。
【００１１】
さらに請求項３記載の発明は、ポンプは別個のエアリフトポンプとし、１個のエアポンプから各々のエアリフトポンプへ空気を送る送気管を設けた請求項２記載の空気清浄機である。
【００１２】
そして、各々の散水ヘッダーへの揚水は１個のエアポンプの運転により送気管を介して別個のエアリフトポンプを作動させて酸性水とアルカリ性水をそれぞれ別個に揚水するので、簡単な構成で酸性水とアルカリ性水を各々の濾過蒸発部へ散水することができ、空気浄化と加湿を行うことができる。
【００１３】
【実施例】
以下本発明の実施例について図面を用いて説明する。
【００１４】
（実施例１）
図１は本発明の実施例１における空気清浄機の構成を示す正面断面図である。また図２は同空気清浄機の構成を示す側面断面図である。
【００１５】
図において本体１５の正面には空気吸い込み口１６を有し、空気吸い込み口１６に対峙して空気通路に臨ませた濾過蒸発部１７を有している。本体１５の下部には水槽１８を有し、本体１５の上部にはファン１９とファン１９を回転させるファンモータ２０を有し、空気吹き出し口２１とを設けている。水槽１８内の水中に一対の電極２２を設け、電極２２の一方は直流電源２３のプラス側に接続して陽極２２ａとし、隔膜２４を隔てた電極２２の他方には直流電源２３のマイナス側を接続して陰極２２ｂとし、濾過蒸発部１７は水槽１８の上方に陽極２２ａ側の濾過蒸発フィルター１７ａと陰極２２ｂ側の濾過蒸発フィルター１７ｂとに分離し、かつ図１、図２から明らかなように並べて設置し、水槽１８の陽極２２ａ側の水と陰極２２ｂ側の水とを各々別個のポンプ２５ａ，２５ｂにより揚水し、陽極２２ａ側の濾過蒸発フィルター１７ａと陰極２２ｂ側の濾過蒸発フィルター１７ｂとの上部にノズル２６ａ，２６ｂにより各々散水するように構成している。
【００１６】
次に動作、作用について説明する。ファンモータ２０を動作させるとファン１９が回転し、空気吸い込み口１６から室内空気が本体１５内へ導入される。また、ポンプ２５ａ，２５ｂが作動すると水槽１８内の水を吸い上げて、ノズル２６ａ，２６ｂから濾過蒸発フィルター１７ａ，１７ｂの各々の上部に散水する。濾過蒸発部１７は空気吸い込み口１６に対峙して空気通路に臨ませているので湿式フィルターとなり、通過する空気中の塵埃を捕捉し、悪臭成分も水の中に溶解吸収して空気を浄化し、浄化された空気はファン１９により空気吹き出し口２１から室内へ放出される。水槽１８内の水は直流電源２３に接続された陽極２２ａと陰極２２ｂにより電気分解され、隔膜２４を挟んで酸性水とアルカリ性水が生成され、濾過蒸発部１７の一方の濾過蒸発フィルター１７ａは酸性水を含み、他方の濾過蒸発フィルター１７ｂはアルカリ性水を含むことになり、酸性ガスはアルカリ性水に吸収されやすく、アルカリ性ガスは酸性水に吸収されやすいため、各種の悪臭成分を除去する性能が向上するとともに、濾過蒸発部１７からは水分の一部が蒸発し空気を加湿することができる。

【００１９】
なお実施例１と同一符号のものは同一構成部であり、詳細な説明は省略する。
【００２０】
次に動作、作用について説明すると、ポンプ２５ａ，２５ｂが作動し吐出管２８ａ，２８ｂを通して散水ヘッダー２９ａ，２９ｂに水槽１８内の酸性水とアルカリ性水が送水されると、散水ヘッダー２９ａ，２９ｂの複数の小孔から水が噴出するが、２枚の布状フィルター２７ａ，２７ｂの上端が複数の孔を有する各々の散水ヘッダー２９ａ，２９ｂを巻き込んだ構成になっているで、散水ヘッダー２９ａ，２９ｂからは空気中に酸性水とアルカリ性水を飛散させることなく、２枚の布状フィルター２７ａ，２７ｂにしみ込ませて落水させる湿式フィルターの構成となるので、空気吹き出し口２１からの水の飛散を防ぐことができる。したがって、水槽１８内の水の損失を少なくし通過する空気中の塵埃の捕捉や、悪臭成分の溶解吸収による空気の浄化や、加湿を、効率良く行うことができる。

実施例２と異なる点は揚水機構を別個のエアリフトポンプ３０ａ，３０ｂとし、１個のエアポンプ３１から各々のエアリフトポンプ３０ａ，３０ｂへ空気を送る送気管３２ａ，３２ｂを設けていることである。
【００２３】
なお実施例１および実施例２と同一符号のものは同一構成部であり、詳細な説明は省略する。
【００２４】
次に動作、作用について説明すると、エアポンプ３１を作動させると、送気管３２ａ，３２ｂよりエアリフトポンプ３０ａ，３０ｂに空気が送られ、水槽１８内の酸性水とアルカリ性水は吐出管２８ａ，２８ｂ内を気泡により持ち上げられ、散水ヘッダー２９ａ，２９ｂの複数の小孔から散水する。１個のエアポンプ３１の作動で２種類の水の揚水が行え、布状フィルター２７ａ，２７ｂは酸性水とアルカリ性水がしみ込んだ湿式フィルターとなり、ファン１９の作動により通過する空気の塵埃の捕捉や、悪臭成分の溶解吸収による空気の浄化や、加湿を、効率良く行うことができる。
【００２５】

【００２８】
次に動作、作用について説明すると、円盤モータ３４を作動させて２個の円盤状フィルター３３ａ，３３ｂを回転させると円盤状フィルター３３ａ，３３ｂの下部は水槽１８内で酸性水およびアルカリ性水に浸漬して吸水し、ファン１９が回転すると円盤状フィルター３３ａ，３３ｂの水面上となった上部が空気が通過する湿式フィルターとなり、散水音や落水音がしないので、空気の浄化と加湿が静穏に行うことができる。
【００２９】
（実施例５）
図９は本発明の実施例５における空気清浄機の構成を示す正面断面図である。また図１０は同空気清浄機の構成を示す側断面図である。
【００３０】
実施例４と異なる点は、接触蒸発部３５を設け、接触蒸発部３５は水槽１８の陽極２２ａ側と陰極２２ｂ側とに分離した各々の複数の吸水性円盤３５ａ，３５ｂで構成され、吸水性円盤３５ａ，３５ｂの下部は水槽１８の陽極２２ａ側の水と陰極２２ｂ側の水とに各々浸漬する位置に設置され、水面上となる吸水性円盤３５ａ，３５ｂの平面の間を空気が通過し、また、複数の吸水性円盤３５ａ，３５ｂは同軸にて円盤モータ３４と連結し回転するように構成したことである。

【００３２】
次に動作、作用について説明する。円盤モータ３４を作動させて複数の吸水性円盤３５ａ，３５ｂを回転させると複数の吸水性円盤３５ａ，３５ｂの下部は水槽１８内で酸性水およびアルカリ性水に各々浸漬して吸水し、ファン１９が回転すると水面上となった複数の吸水性円盤３５ａ，３５ｂの平面の間を空気が通過し、複数の吸水性円盤３５ａ，３５ｂの表面水にて通過する空気の塵埃の捕集や悪臭成分の溶解吸収および水分の蒸発加湿が行われる。従って複数の吸水性円盤３５ａ，３５ｂの平面の間を空気が通過するので空気通過の圧力損失は小さく、低騒音で大風量の運転が行うことができ、室内の混合攪拌効率を大きくすることができる。
【００３３】
【発明の効果】
以上の説明から明らかなように請求項１記載の発明によれば、空気吸い込み口と、水中に設け、一方は直流電源のプラス側に接続した陽極及び他方は前記直流電源のマイナス側に接続した陰極からなる一対の電極と前記電極間に設け、水中のイオン性物質は自由に通過する隔膜を有する水槽と、前記空気吸い込み口に臨ませて前記水槽の上方に前記陽極側と前記陰極側とに分離し並設して、前記空気吸い込み口より吸引された空気を濾過し、かつ前記水槽の水で濡れた水分の一部が蒸発する濾過蒸発部と、前記水槽の前記陽極側の水と前記陰極側の水とを各々別個に前記濾過蒸発部の上部へ揚水する各々別個のポンプと、送風機と、空気吹き出し口とを備え、前記濾過蒸発部の前記陽極側と前記陰極側の上部に各々別個のノズルを設け、前記ノズルにより前記ポンプが揚水した水を前記濾過蒸発部の前記陽極側と前記陰極側の上部より散水する構成としたので、空気吸い込み口に臨ませている濾過蒸発部が湿式フィルターとなり、通過する空気中の塵埃を捕捉し、悪臭成分も水の中に溶解吸収し空気を浄化する。特に水槽内の水は電気分解され、隔膜を挟んで酸性水とアルカリ性水が生成され、分離された一方の濾過蒸発部は酸性水を含み、他方の濾過蒸発部はアルカリ性水を含むことになり、酸性ガスはアルカリ性水に吸収されやすく、アルカリ性ガスは酸性水に吸収されやすいため、各種の悪臭成分を除去する性能が向上する。また、濾過蒸発部からは水分の一部が蒸発し空気を加湿することができる。さらに、水槽内や濾過蒸発部の水は酸性またはアルカリ性に維持されるためバクテリアの繁殖を抑制でき衛生的である。
【００３４】
また、請求項２記載の発明によれば、濾過蒸発部は水槽の上方に陽極側と陰極側とに分離した２枚の布状フィルターを設置し、水槽の陽極側の水と陰極側の水とを各々別個のポンプにより揚水し、前記ポンプが揚水した水を前記濾過蒸発部の前記陽極側と前記陰極側の上部より散水する別個の複数の孔を有する散水ヘッダーを設け、前記布状フィルターはそれぞれの上端が各々の散水ヘッダーを巻き包んで構成しているので、散水ヘッダーから空気中に酸性水とアルカリ性水とを飛散させることなく、２枚の布状フィルターにしみ込ませて落水させる湿式フィルターとなり、通過する空気中の塵埃の捕捉や、悪臭成分の溶解吸収による空気の浄化や、加湿を、空気吹き出し口からの水を飛散させることなく水槽内の水の損失を少なくし効率良く行うことができる。
【００３５】
さらに、請求項３記載の発明によれば、ポンプは別個のエアリフトポンプとし、１個のエアポンプから各々のエアリフトポンプへ空気を送る送気管を設けた構成としたので、散水ヘッダーへの揚水は１個のエアポンプの運転により２個のエアリフトポンプを作動させて酸性水とアルカリ水をそれぞれ別個に揚水するので、簡単な構成で酸性水とアルカリ性水各々の濾過蒸発部へ散水することができ、効率の良い空気浄化と加湿を低コストで行うことができる。

Also, the water in the aquarium is electrolyzed to produce acidic water and alkaline water across the diaphragm, and one separated filtration evaporation section contains acidic water, and the other filtration evaporation section contains alkaline water. In addition, acid gas is easily absorbed by alkaline water, and alkaline gas is easily absorbed by acidic water, so the performance of removing various malodorous components is improved, and part of the water evaporates from the filter evaporation unit to humidify the air. can do. In addition, since the water in the water tank can be kept acidic and alkaline, it is possible to prevent the growth of bacteria in the water tank, and the filtration evaporation part is also sprinkled with acidic water or alkaline water, so that the growth of bacteria can be prevented.
[0007]
