Abstract

An inflow portion and an outflow portion are formed in a filtration member by providing a channel in a porous body, wherein the channel consists of a first channel which is sealed on the side of the inflow portion of the body and a second channel which is sealed on the side of the outflow portion of the body, and the other channel is arranged at a position contiguous to any one of the first or second channel so that the discharge rate is prevented from dropping due to clogging thus attaining longer life of the filtration member.

Description

濾過部材およびそれを備える浄水カートリッジFiltration member and water purification cartridge provided with the same
　本発明は、濾過部材およびそれを備える浄水カートリッジに関する。 The present invention relates to a filtration member and a water purification cartridge provided with the same.
　従来、濾過部材として、多数の流通路を連通させた多孔質フィルターの線状に連続して隣接する流通路を一端面において封止するとともに、残余の流通路を他端面において封止することで、流入側に開口した流通路と流出側に開口した流通路とを形成したものが知られている（例えば、特許文献１参照）。 Conventionally, as a filtration member, a linear adjacent continuous flow passage of a porous filter in which a large number of flow passages are communicated is sealed at one end surface, and the remaining flow passages are sealed at the other end surface. There is known one in which a flow passage opened to the inflow side and a flow passage opened to the outflow side are formed (see, for example, Patent Document 1).
　そして、流入側に開口した流通路に流入した水を多孔質フィルターの基体を通過させて流出側に開口した流通路に流入させるようにしている。 Then, the water flowing into the flow passage opened to the inflow side is allowed to pass through the base of the porous filter and to flow into the flow passage opened to the outflow side.
特開２００３－０８００４１号公報JP 2003-080041
　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いる。そのため、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。その結果、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-mentioned prior art, linearly continuous adjacent flow passages are sealed at one end face. Therefore, the proportion of the portion of the porous filter substrate which can send the water in the flow passage opened to the inflow side to the flow passage opened to the outflow side is low. As a result, 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 the present invention is to obtain a filtration member which can aim at extension of life, and a water purification cartridge provided with the same.
　本発明にあっては、多孔質の本体に流路を設けて流入部と流出部とを形成した濾過部材であって、前記流路は、前記本体の流入部側が封止される第１流路と、当該本体の流出部側が封止される第２流路と、で構成されており、前記第１および第２流路のうちいずれか一方の流路と隣り合う位置に他方の流路を配設したことを特徴とする。 In the present invention, it is a filtration member in which a flow path is provided in a porous main body to form an inflow portion and an outflow portion, and the flow path is a first flow in which the inflow portion side of the main body is sealed. And a second flow path in which the outlet portion side of the main body is sealed, and the other flow path at a position adjacent to any one of the first and second flow paths. Are disposed.
　本発明によれば、多孔質の本体に第１および第２流路を設け、第１および第２流路のうちいずれか一方の流路と隣り合う位置に他方の流路を配設している。こうすれば、多孔質の本体のうち、第１流路から第２流路へと水を送ることのできる部分の割合を高めることができるようになる。その結果、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、濾過部材の長寿命化を図ることができるようになる。 According to the present invention, the porous main body is provided with the first and second flow channels, and the other flow channel is disposed adjacent to any one of the first and second flow channels.

Furthermore, the center 16 a of the inflow side flow path 16 is arranged at the center of gravity of the regular hexagon formed by connecting the centers (centroids) 15 a of the outflow side flow path 15.
　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 vertex of the substantially regular hexagon (substantially regular polygon), but as shown in FIG. Eight outflow side flow paths 15 may be disposed around the side flow path 16 so that the outflow side flow path 15 is located at the top 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てもよい。また、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てもよい。また、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。 Further, in the present embodiment, the cross-sectional shapes of the outflow side flow passage 15 and the inflow side flow passage 16 are circular with substantially the same diameter, but as shown in FIGS. 5 (a) to 5 (c), the outflow side flow passage and The cross-sectional shape of the inflow side flow path is the outflow side flow path 15A and the inflow side flow path 16A of a substantially regular triangle, and the center of gravity of the outflow side flow path 15A is located at the vertex of a substantially regular triangle (substantially regular polygon). You may arrange. Alternatively, the outflow side flow passage 15B and the inflow side flow passage 16B may be substantially square, and the gravity center of the outflow side flow passage 15B may be disposed at the vertex of a substantially square (substantially regular polygon). Further, it is possible to arrange the outflow side flow passage 15C and the inflow side flow passage 16C of a substantially regular hexagon so that the center of gravity of the outflow side flow passage 15C is located at the vertex of a substantially regular hexagon (substantially regular polygon) is there. At this time, the sides of the outflow side flow path are made to face the sides of the inflow side flow path, and the thicknesses of the wall portions between each of the outflow side flow paths and the inflow side flow path are substantially the same. It is preferable to set it.
　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る。そして、流出側流路１５内に送られ、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 allowed to flow into the inflow side flow passage 16 from the inflow portion 12 side of the main body 11 of the filtration member 10 configured as described above, the water in the inflow side flow passage 16 is the inflow side as shown in FIG. It is filtered by permeate | transmitting the wall part 18 between the flow path 16 and the outflow side flow path 15. As shown in FIG. Then, the water is sent into the outflow side flow passage 15, and the water in the outflow side flow passage 15 flows out from the outflow portion 13 of the main body 11 and flows out from the outflow port 3.
　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を配設している。こうすれば、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。その結果、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 above embodiment, the porous main body 11 is provided with the outflow side flow path (first flow path) 15 and the inflow side flow path (second flow path) 16, and the outflow side flow path 15 and the inflow side flow The outflow side flow passage 15 is disposed at a position adjacent to any one of the inflow side flow passages 16 in the passage 16. By so doing, it is possible to increase the proportion of the wall portion 18 that can send water from the first flow path to the second flow path in the porous main body 11. As a result, it is possible to suppress a decrease in the discharge amount due to clogging, and to prolong the life of the filtration member 10.
　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している。こうすれば、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。その結果、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。そのため、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ができ、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。 Moreover, while making the cross-sectional shapes of the inflow side flow path (one flow path) 16 and the outflow side flow path (the other flow path) 15 substantially the same circle, the outflow side flow path (the other flow path) 15 The center (center of gravity) 15a of the outflow side channel 15 is positioned at the vertex of a substantially regular hexagon or a substantially square (substantially regular polygon) in a sectional view orthogonal to the axis C direction (the extending direction of the channel 14). It is arranged. In this way, the wall portion 18 between the inflow side flow passage (one flow passage) 16 and each outflow side flow passage (the other flow passage) 15 surrounding the inflow side flow passage (one flow passage) 16 Can be suppressed from becoming thick. As a result, the pressure loss in the wall can be reduced, and water can be discharged more efficiently. In addition, by positioning the outflow side flow path 15 and the inflow side flow path 16 with regularity, it is possible to position the outflow side flow path 15 and the inflow side flow path 16 by positioning at the top of the substantially regular polygon. Therefore, it can suppress that the site | part to which the thickness of the wall part 18 becomes thin extremely is formed, and can suppress that the intensity | strength of the main body 11 falls. 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。 In addition, as in the second to fourth modified examples of the present embodiment, even if the shapes of the outflow side flow passage and the inflow side flow passage are substantially polygonal and arranged with regularity, substantially the same operation as described above It can produce an effect. In addition, it becomes easy to adjust the thickness of the wall between each of the outflow side flow passage and the inflow side flow passage, and the pressure loss at the wall portion is reduced while suppressing the reduction of the strength of the main body Will 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。そのため、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。 Further, by making the thickness of the wall portion more uniform, it is possible to reduce the difference in pressure loss in the circumferential direction of the inflow side flow passage. Therefore, it can suppress that movement of water from the inflow side channel to the outflow side channel is biased to a predetermined location, and it becomes possible to achieve further extension of the life of the filtration member. That is, as shown in FIG. 5, when the cross-sectional shape of the flow path is a substantially regular polygon, it is possible to obtain the filtration member 10 capable of achieving long 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 exhibits the said effect can be obtained.
