Description
図1は、本発明の浄水カートリッジ(4)の一例を示す模式断面図である。
なお、輸送途中や濾過途中に繊維状濾材(23)がずれたり抜け落ちたりしない様に、繊維状濾材(23)の上下に支持部材を配し、筒状容器内に固定する事が望ましい。
浄水器(1)は、上方が開口した外容器(5)と、この外容器(5)の開口端を塞ぐ蓋(3)と、外容器(5)の内部に配置された内容器(6)と、内容器(6)に取り付けられた浄水カートリッジ(4)とを備えている。
蓋(3)の材質は、外容器(5)と同様のものを用いることができ、抗菌特性を付加してもよい。
粒径0.4〜0.8mmの粒状濾材(22)70mlに対し、表1に示したとおりの各々空隙率の異なる繊維状濾材(23)13mlを使用して、図1に示すような構造の浄水カートリッジ(4)をそれぞれ作製し、この浄水カートリッジ(4)を、図4に示す構造のピッチャー型の浄水器(1)の原水貯留部(10)と浄水貯留部(11)との間に配した。
この浄水器(1)を用いて水1Lを自重により濾過した。表1に、各実施例及び比較例で用いた繊維状濾材の空隙率と濾過時間および濾過によって流出した微粉の有無とを表1に示した。
粒径0.4〜0.8mmの粒状濾材(22)70mlと、表2に示した通り繊維状活性炭とイオン交換繊維の重量配合の各々異なる混合体にバインダーを加えて成型した繊維状濾材(23)13mlを使用して、図1に示すような構造の浄水カートリッジ(4)をそれぞれ作製し、この浄水カートリッジ(4)を、図4に示す構造のピッチャー型の浄水器(1)の原水貯留部(10)と浄水貯留部(11)との間に配した。
この浄水器(1)を用いて水1Lを自重で濾過し、浄水カートリッジ(4)が水没した状態のまま冷蔵庫内で15時間保管した水を検体とした。さらに実施例5と同様の混合割合の繊維状濾材を使用した浄水器(1)を用いて同様の方法で水を濾過したあと、浄水カートリッジ(4)を取り外して冷蔵庫で15時間保管した水をコントロールとし、それぞれ官能試験を行った結果を表3に示した。
(1) 検体及びコントロールを20℃に温度調整する。
(2) 同一形状のコップに、検体及びコントロールをそれぞれ入れる。
(3)どの水が検体であり、どの水がコントロールかは伏せた状態で、パネラーに水を飲んでもらい、それぞれ10点満点で採点してもらう。
粒径0.4〜0.8mmの粒状濾材(22)と、繊維状濾材(23)の容積の割合を、各々表4のごとく変え、図1に示すような構造の浄水カートリッジ(4)をそれぞれ作製し、この浄水カートリッジ(4)を、図4に示す構造のピッチャー型の浄水器(1)の原水貯留部(10)と浄水貯留部(11)との間に配した。
そして、この浄水器(1)を用いて水1Lを自重で濾過した。表4に、各実施例及び比較例で用いた繊維状濾材の空隙率と濾過時間および濾過によって流出した微粉の有無とを示した。
