しかしながら、上記従来の技術では、線状に連続して隣接する流通路を一端面において封止しており、多孔質フィルターの基体のうち、流入側に開口した流通路内の水を流出側に開口した流通路へと送ることのできる部分の割合が低いため、目詰まりによって吐出量が早期に低下してしまうおそれがあり、多孔質フィルターの長寿命化を図りがたかった。   However, in the above conventional technique, the flow passages that are continuously adjacent to each other in a linear shape are sealed at one end surface, and the water in the flow passage that is open to the inflow side of the porous filter base is directed to the outflow side. Since the ratio of the portion that can be sent to the open flow passage is low, there is a possibility that the discharge amount may be reduced early due to clogging, and it has been difficult to extend the life of the porous filter.

そこで、本発明は、長寿命化を図ることのできる濾過部材およびそれを備える浄水カートリッジを得ることを目的とする。   Then, an object of this invention is to obtain the filtration member which can aim at lifetime improvement, and a water purification cartridge provided with the same.

The center 16a of the inflow side flow path 16 is arranged at the center of gravity of a regular hexagon formed by connecting the center (center of gravity) 15a of the outflow side flow path 15. I have to.

なお、本実施形態では、流出側流路１５の中心（重心）１５ａが略正六角形（略正多角形）の頂点に位置するように配設しているが、図４に示すように、流入側流路１６の周囲に８個の流出側流路１５を配設して、流出側流路１５が正方形の頂点に位置するようにしてもよい。   In the present embodiment, the center (center of gravity) 15a of the outflow side flow passage 15 is disposed at the apex of a substantially regular hexagon (substantially regular polygon). However, as shown in FIG. Eight outflow channels 15 may be provided around the side channels 16 so that the outflow channels 15 are located at the apexes of the square.

また、本実施形態では、流出側流路１５および流入側流路１６の断面形状をほぼ同径の円形としているが、図５（ａ）〜（ｃ）に示すように、流出側流路および流入側流路の断面形状を、略正三角形の流出側流路１５Ａおよび流入側流路１６Ａとし、流出側流路１５Ａの重心が略正三角形（略正多角形）の頂点に位置するように配設したり、略正方形の流出側流路１５Ｂおよび流入側流路１６Ｂとし、流出側流路１５Ｂの重心が略正方形（略正多角形）の頂点に位置するように配設したりしてもよいし、略正六角形の流出側流路１５Ｃおよび流入側流路１６Ｃとし、流出側流路１５Ｃの重心が略正六角形（略正多角形）の頂点に位置するように配設することも可能である。このとき、流出側流路の辺と流入側流路の辺とを対向させるとともに、流出側流路のそれぞれと流入側流路との間の壁部の厚さがほぼ同一となるように配設するのが好適である。   Moreover, in this embodiment, although the cross-sectional shape of the outflow side flow path 15 and the inflow side flow path 16 is made into the circle | round | yen with substantially the same diameter, as shown to Fig.5 (a)-(c), The cross-sectional shape of the inflow side flow path is a substantially equilateral triangular outflow side flow path 15A and inflow side flow path 16A, and the center of gravity of the outflow side flow path 15A is positioned at the apex of a substantially regular triangle (substantially regular polygon). Or a substantially square outflow channel 15B and inflow channel 16B, and the center of gravity of the outflow channel 15B is positioned at the apex of a substantially square (substantially regular polygon). Alternatively, a substantially regular hexagonal outflow side channel 15C and an inflow side channel 16C may be provided so that the center of gravity of the outflow side channel 15C is positioned at the apex of a substantially regular hexagon (substantially regular polygon). Is possible. At this time, the side of the outflow side channel and the side of the inflow side channel are opposed to each other, and the wall portions between the outflow side channel and the inflow side channel are arranged to have substantially the same thickness. It is preferable to install.

このように構成された濾過部材１０の本体１１の流入部１２側から水を流入側流路１６内に流入させると、図１に示すように、流入側流路１６内の水は当該流入側流路１６と流出側流路１５との間の壁部１８を透過することで濾過され、流出側流路１５内に送られる。そして、流出側流路１５内の水が本体１１の流出部１３から流出して流出口３から流出される。   When water is caused to flow into the inflow side flow channel 16 from the inflow portion 12 side of the main body 11 of the filter member 10 configured as described above, the water in the inflow side flow channel 16 is transferred to the inflow side as shown in FIG. By passing through the wall portion 18 between the flow path 16 and the outflow side flow path 15, it is filtered and sent into the outflow side flow path 15. And the water in the outflow side flow path 15 flows out from the outflow part 13 of the main body 11, and flows out from the outflow port 3. FIG.

以上の本実施形態によれば、多孔質の本体１１に流出側流路（第１流路）１５および流入側流路（第２流路）１６を設け、流出側流路１５および流入側流路１６のうちいずれか一方の流入側流路１６と隣り合う位置に流出側流路１５を配設することで、多孔質の本体１１のうち第１流路から第２流路へと水を送ることのできる壁部１８の割合を高めることができるようになるため、目詰まりによって吐出量が低下してしまうのを抑制することができ、濾過部材１０の長寿命化を図ることができる。   According to the present embodiment, the outflow side flow path (first flow path) 15 and the inflow side flow path (second flow path) 16 are provided in the porous main body 11, and the outflow side flow path 15 and the inflow side flow are provided. By disposing the outflow side flow path 15 at a position adjacent to any one of the inflow side flow paths 16 in the path 16, water is supplied from the first flow path to the second flow path in the porous main body 11. Since the ratio of the wall portion 18 that can be sent can be increased, it is possible to suppress the discharge amount from being reduced due to clogging, and the life of the filter member 10 can be extended.

また、流入側流路（一方の流路）１６と流出側流路（他方の流路）１５の断面形状を略同一の円形とするとともに、流出側流路（他方の流路）１５を、軸Ｃ方向（流路１４の延在方向）に直交する断面視で、流出側流路１５の中心（重心）１５ａが略正六角形や略正方形（略正多角形）の頂点に位置するように配設することで、流入側流路（一方の流路）１６と当該流入側流路（一方の流路）１６を囲うそれぞれの流出側流路（他方の流路）１５との間の壁部１８の厚さが厚くなってしまうのを抑制することができるため、壁部における圧力損失を低減させることができ、より効率的に水を吐出させることができるようになる。また、略正多角形の頂点に位置させることで、流出側流路１５および流入側流路１６を規則性をもって配設することが可能となるため、壁部１８の厚さが極端に薄くなってしまう部位が形成されるのを抑制することもでき、本体１１の強度が低下してしまうのを抑制することができる。また、流路１４の構成を簡素化できるため、本体１１を容易に製造することができるようになるという利点もある。   In addition, the inflow side flow path (one flow path) 16 and the outflow side flow path (the other flow path) 15 have substantially the same circular cross section, and the outflow side flow path (the other flow path) 15 The center (center of gravity) 15a of the outflow side flow passage 15 is positioned at the apex of a substantially regular hexagon or a substantially square (substantially regular polygon) in a cross-sectional view orthogonal to the axis C direction (extending direction of the flow passage 14). By disposing, the wall between the inflow side flow path (one flow path) 16 and each outflow side flow path (the other flow path) 15 surrounding the inflow side flow path (one flow path) 16 Since it can suppress that the thickness of the part 18 becomes thick, the pressure loss in a wall part can be reduced and water can be discharged more efficiently. Moreover, since the outflow side flow path 15 and the inflow side flow path 16 can be arranged with regularity by being positioned at the apex of the substantially regular polygon, the thickness of the wall portion 18 becomes extremely thin. It is also possible to suppress the formation of a portion that would cause the strength of the main body 11 to be reduced. Moreover, since the structure of the flow path 14 can be simplified, there is also an advantage that the main body 11 can be easily manufactured.

なお、本実施形態の第２から第４変形例のように、流出側流路および流入側流路の形状を略多角形状とし、規則性をもって配置させるようにしても、上記とほぼ同様の作用効果を奏することができる。また、流出側流路のそれぞれと流入側流路との間の壁部の厚さの調整が容易になり、本体の強度が低下してしまうのを抑制しつつ、壁部における圧力損失を低減させることができるようになる。   Note that, as in the second to fourth modifications of the present embodiment, even if the outflow side flow path and the inflow side flow path have a substantially polygonal shape and are arranged with regularity, substantially the same operation as described above. There is an effect. In addition, the thickness of the wall between each of the outflow channels and the inflow channel can be easily adjusted, and the pressure loss at the walls is reduced while preventing the strength of the main body from being reduced. To be able to.

また、壁部の厚さをより均等にさせることで、流入側流路の周方向における圧力損失の差を低減させることができるため、流入側流路から流出側流路への水の移動が所定の箇所に偏ってしまうのを抑制することができ、濾過部材のさらなる長寿命化を図ることができるようになる。すなわち、図５に示すように、流路の断面形状を略正多角形とすれば、より簡素な構成で長寿命化を図ることのできる濾過部材１０を得ることができる。   In addition, since the difference in pressure loss in the circumferential direction of the inflow side flow path can be reduced by making the thickness of the wall portion more uniform, the movement of water from the inflow side flow path to the outflow side flow path can be reduced. It is possible to suppress the bias to a predetermined location, and it is possible to further extend the life of the filtration member. That is, as shown in FIG. 5, if the cross-sectional shape of the flow path is a substantially regular polygon, it is possible to obtain the filter member 10 that can achieve a longer life with a simpler configuration.

また、本実施形態によれば、上記作用効果を奏する濾過部材１０を装備した浄水カートリッジ１を得ることができる。   Moreover, according to this embodiment, the water purification cartridge 1 equipped with the filtration member 10 which has the said effect can be obtained.
