WATER PURIFIER AND WATER PURIFYING CARTRIDGE THEREFOR

摘要

PURPOSE:To maintain water purifying performance by a water purifying cartridge for a water purifier for by arranging an antibacterial means for dissolving out copper ions or metallic ions which have ionization tendency larger than the copper ions and have antibacterial properties in the inlet side of raw material in a water purifying filter of a hollow yarn membrane arranged with an extremely fine steel fibrous body. CONSTITUTION:A water purifying cartridge 4 for a water purifier is built-in to the inside of the water purifier and constituted of the water purifying filter of a hollow yarn membrane, activated carbon or combination thereof. An extremely fine steel fibrous body D is arranged in the outlet side of clean water in the water purifying filter of the hollow yarn membrane. The water purifier is constituted so that antibacterial substance A, B being an antibacterial means are arranged in the inlet side of raw water in the water purifying filter of the hollow yarn membrane. The antibacterial means dissolves out copper ions or metallic ions which have ionization tendency larger than the copper ions and have antibacterial properties. Thereby, prevention of deterioration is performed in the outlet side of clean water in the hollow yarn membrane in order to prolong the service life of the antibacterial substances A, B.
