The inside of the cylindrical main body case 1 is equipped with a raw water inlet 2 and a purified water outlet 3 at the bottom. A partition wall 4 is erected in the chamber to separate a primary filtration chamber 5 filled with activated carbon powder 8 and a hollow fiber membrane 16. The installed secondary filtration chambers 6 are communicated with each other at the upper part of the main body case 1. The above-mentioned water is passed through a primary filter 7 which is divided into sections and has a primary filtration chamber 5 at its lower end. It communicates with the raw water inlet 2, the lower part of the secondary filtration chamber 6 communicates with the purified water outlet 3, and The secondary filter 11 is fitted and fixed to the upper end of the secondary filtration chamber 5, and the main body case 1 is The upper end opening is sealed with a lid 12 fixed with adhesive, and the partition wall 4 is cylindrical.

【考案が解決しようとする課題】 しかしながら、上述した従来例には次のような問題点がある。 すなわち、一次濾過室5内に活性炭粉8を充填する際に、舞い上がった活性炭 粉8が本体ケース1上端の蓋接合面1aに付着することがあり、この付着した活 性炭粉8によって蓋12の接着不良が生じることがあった。また、飛散した活性 炭粉が二次濾過室6にまで及んで中空糸膜16に付着してそれを傷つけるおそれ もあった。特に蓋12が透明の場合には、中空糸膜16が当初から汚損されてい るように見えてしまうという不具合もあった。[Problem that the idea aims to solve] However, the conventional example described above has the following problems. That is, when filling the primary filtration chamber 5 with activated carbon powder 8, the activated carbon that flies up Powder 8 may adhere to the lid joint surface 1a at the upper end of the main body case 1, and this adhered powder may The charcoal powder 8 sometimes caused poor adhesion of the lid 12. In addition, the scattered active There is a risk that the charcoal powder will reach the secondary filtration chamber 6 and adhere to the hollow fiber membrane 16, damaging it. There was also. In particular, when the lid 12 is transparent, the hollow fiber membrane 16 is not contaminated from the beginning. There was also a problem that it looked like it was
【0006】 さらに、上記フィルタカートリッジの組立てにおいて、一次濾過室5の上端ま で活性炭粉8を充填した状態で二次フィルタ11を装着すると、嵌合部が弾性変 形して一気に嵌り込むため、その勢いによって内部の活性炭粉8が舞い上がりや すく、舞い上がった活性炭粉8が本体ケース1上端の蓋接合面1aに付着し、上 記と同様の問題が生じることがあった。[0006] Furthermore, in assembling the filter cartridge, the upper end of the primary filtration chamber 5 is When the secondary filter 11 is attached with the activated carbon powder 8 filled in the Since it is shaped and fitted all at once, the activated carbon powder 8 inside will fly up due to the force. The activated carbon powder 8 that flies up adheres to the lid joint surface 1a at the upper end of the main body case 1, and A problem similar to the one mentioned above sometimes occurred.
【0007】 本考案は、このような事情に鑑みてなされたものであり、一次濾過室の構成に 改良を加えることで、活性炭粉が舞い上がることがないように充填して上記不具 合を解消することを目的とする。[0007] The present invention was developed in view of these circumstances, and it is based on the structure of the primary filtration chamber. By making improvements, the activated carbon powder can be filled in such a way that it does not fly up, and the above-mentioned problems can be solved. The purpose is to resolve the situation.
