Description
前記電気集塵装置が、放電電極と対向電極の間でコロナ放電を生じさせて空気中の粒子を帯電させるイオン化部と、このイオン化部で帯電された空気中の粒子を集塵するコレクタ部と、定電流制御のもとで前記放電電極と前記対向電極間に電圧を印加する高圧電源とを備え、
前記高圧電源は、垂下特性を有するとともに、200μA以下の定電流制御のもとで、プラスもしくはマイナスの直流の3〜6kVの電圧を印加する構成とするものである。
図1は本発明の実施の形態1に係る空気処理装置の概要を示す部分断面側面図であり、図2はその上部の部分断面上面図である。
本実施の形態1に係る空気処理装置は、キャビネット1と、キャビネット1の奥側に立設された吸い込みフード2とを備え、キャビネット1内に本空気処理装置の本体部3が配置されている。また、キャビネット1の上部には電気加熱器具4が配置され、この電気加熱器具4の下側に本空気処理装置の本体部3が配置されている。
また、風路6は、図2に示すように、キャビネット1の中央部を通る吸引路6aと、キャビネット1の側面側を通る2つの送風路6bとに分割されており、上記プレフィルタ7、プレ脱臭フィルタ8、集塵手段9、およびメイン脱臭フィルタ10は吸引路6a内に配置され、送風機11と排気口脱臭フィルタ12は上記2つの送風路6bのそれぞれに配置されている。
上記のように構成された空気処理装置においては、電気加熱器具4による調理時に発生した水蒸気、油煙、臭気等の汚染空気が送風機11により吸引され、吸い込みフード2に取り付けられた第1の油煙・水蒸気除去手段である吸込み口フィルタ5で汚染空気中の油煙、水蒸気の大半が除去される。その後、吸い込まれた空気は、プレフィルタ7を通過し、さらに油煙、水蒸気が除去される。吸込み口フィルタ5とプレフィルタ7により、吸引された汚染空気中の油煙、水蒸気のうち70%以上が捕集される。その後、吸い込まれた空気は、プレ脱臭フィルタ8を通過し、臭気が除去される。プレ脱臭フィルタ8は、その風下側に設置される集塵手段9に付着する臭気を抑制する効果がある。集塵手段9には高電圧が印加されており、気流中の残った水蒸気、油煙に対してイオン化部17でコロナ放電により電荷を与えて、この荷電粒子がコレクタ部18を通過する間に静電気力により集塵電極に捕集されて除去される。その後、油煙・水蒸気が除去された空気は、メイン脱臭フィルタ10を通過する。メイン脱臭フィルタ10を通過することにより、気流中の臭気はメイン脱臭フィルタ10に吸着剤や触媒、化学薬品等の脱臭剤を1種類以上含有させる構成とすることにより除去され、これによって清浄化された空気が排気口脱臭フィルタ12を通過してさらに清浄化され吹き出し口から外に吹き出す。
図5は本発明の実施の形態2に係る空気処理装置の正面図である。図において、実施の形態1と同一の符号は同一または相当部分を示す。本実施の形態2では、吸い込みフード2に取り付けられた第1の油煙・水蒸気除去手段である吸込み口フィルタ5の近傍に湿度センサ16を設置したものである。その他の構成は実施の形態1と同じであるので説明は省略する。
湿度センサ16により、流入する汚染空気の湿度を検知し、集塵手段9に接続される電源の印加電圧を下記の式により決定する。
印加電圧(kV)=−1/30×湿度(%)+6.5
これにより、流入した汚染空気の湿度に適した電圧が印加されることになる。
