Description

本発明は、活性炭成型体、濾過カートリッジ、及び、浄水器に関する。 The present invention relates to an activated carbon molded body, a filtration cartridge, and a water purifier.

水道水に含まれる遊離残留塩素や有機物等の微量成分を除去する活性炭をカートリッジ化した浄水カートリッジにより水を浄化する浄水器が知られている。特許文献１には、風呂場や洗面所で使用するために浄水カートリッジを収容したシャワーヘッドが開示されている。この浄水カートリッジには、活性炭を主成分とした水質浄化材を円筒状に固めた活性炭成型体を用いている。この活性炭成型体は、浄水が流出する断面円形の貫通孔が中心軸に沿って設けられ、原水が外側面から前記貫通孔まで通過することにより浄化する。活性炭成型体に形成された流路用の孔は、前記断面円形の貫通孔しかない。 There is known a water purifier that purifies water with a water purification cartridge in which activated carbon that removes trace components such as free residual chlorine and organic substances contained in tap water is made into a cartridge. Patent Document 1 discloses a shower head containing a water purification cartridge for use in a bathroom or a washroom. For this water purification cartridge, an activated carbon molded body obtained by solidifying a water purification material containing activated carbon as a main component into a cylindrical shape is used. In this activated carbon molded body, a through hole having a circular cross section through which purified water flows out is provided along the central axis, and the raw water is purified by passing from the outer surface to the through hole. The only hole for the flow path formed in the activated carbon molded body is the through hole having a circular cross section.

浄水器のユーザビリティーを向上させるため、浄水カートリッジの小型化が求められている。単位体積における活性炭の吸着性能を向上させることができれば、浄水カートリッジの小型化に繋がる。単位体積における活性炭の吸着性能を向上させるために粒状活性炭の粒径を小さくすると、活性炭の粒子間の空隙が小さくなり、不織布で除去することができない水中の微粒子が前記空隙で捕捉される。この結果、浄水カートリッジが目詰まりしたり、微量成分を除去する機能を発揮する活性炭自体の孔が有効に活用されなかったりする。 In order to improve the usability of water purifiers, miniaturization of water purification cartridges is required. If the adsorption performance of activated carbon in a unit volume can be improved, it will lead to the miniaturization of the water purification cartridge. When the particle size of the granular activated carbon is reduced in order to improve the adsorption performance of the activated carbon in a unit volume, the voids between the particles of the activated carbon become smaller, and the fine particles in water that cannot be removed by the non-woven fabric are captured by the voids. As a result, the water purification cartridge may be clogged, or the holes of the activated carbon itself, which exerts the function of removing trace components, may not be effectively utilized.

尚、上述のような問題は、空気清浄機用の濾過カートリッジ等、浄水カートリッジ以外の濾過カートリッジ等にも存在する。
本発明は、濾過カートリッジ等といった活性炭成型体を使用した製品を小型化することが可能な技術を開示するものである。 The above-mentioned problems also exist in filtration cartridges other than water purification cartridges, such as filtration cartridges for air purifiers.
The present invention discloses a technique capable of miniaturizing a product using an activated carbon molded body such as a filtration cartridge.

［態様１］
本技術の一態様に係る活性炭成型体１００は、活性炭ＡＣ１を含む活性炭成型体１００であって、流体（例えば水Ｗ）が流入する一以上の流入凹部１１１の開口端１１２が配置された流入端部１１０と、前記流体（Ｗ）が流出する一以上の流出凹部１２１の開口端１２２が配置された流出端部１２０と、前記流入端部１１０から前記流出端部１２０に繋がる側面部（例えば外側面１３０）と、を有する。前記流入凹部１１１は、前記流出端部１２０側の端部に閉塞した第一閉塞端１１３を有している。前記流出凹部１２１は、前記流入端部１１０側の端部に閉塞した第二閉塞端１２３を有している。前記第一閉塞端１１３は、前記第二閉塞端１２３よりも前記流出端部１２０側にある。 [Aspect 1]
The activated carbon molded body 100 according to one aspect of the present technology is an activated carbon molded body 100 containing activated carbon AC1, and is an inflow end in which an opening end 112 of one or more inflow recesses 111 into which a fluid (for example, water W) flows is arranged. A portion 110, an outflow end 120 in which the opening ends 122 of one or more outflow recesses 121 from which the fluid (W) flows out are arranged, and a side surface portion (for example, outside) connected from the inflow end 110 to the outflow end 120. The side surface 130) and. The inflow recess 111 has a first closed end 113 that is closed at the end on the outflow end 120 side. The outflow recess 121 has a second closed end 123 that is closed at the end on the inflow end 110 side. The first closed end 113 is closer to the outflow end portion 120 than the second closed end 123.

上記態様１において、流入凹部１１１が流入端部１１０から第一閉塞端１１３まで凹み、流出凹部１２１が流出端部１２０から第二閉塞端まで凹み、且つ、第一閉塞端１１３が第二閉塞端１２３よりも流出端部１２０側にあるので、第一閉塞端１１３と第二閉塞端１２３との間の横断面ＣＳ１において流入凹部１１１と流出凹部１２１の両方が存在する。流入凹部１１１の開口端１１２から流入凹部１１１に流入した流体（Ｗ）は、流入凹部１１１の内側面１１４から活性炭成型体１００内に入り、少なくとも一部が横断面ＣＳ１に沿った方向（例えば図５，６に示す方向Ｄ３，Ｄ４）にある流出凹部１２１へ移動して流出凹部１２１の開口端１２２から外部へ流出する。活性炭成型体１００内において、流体（Ｗ）が濾過されて浄化される。横断面ＣＳ１において流入凹部１１１と流出凹部１２１の両方が存在することにより、流体（Ｗ）の圧力損失が低くなり、濾過流量を多くすることができる。このため、例えば、活性炭の粒子を小さくすることができ、単位体積における活性炭量を増やして活性炭の吸着性能を向上させることができる。従って、本態様は、活性炭成型体を使用した製品を小型化することが可能な技術を提供することができる。 In the first aspect, the inflow recess 111 is recessed from the inflow end 110 to the first closed end 113, the outflow recess 121 is recessed from the outflow end 120 to the second closed end, and the first closed end 113 is the second closed end. Since it is closer to the outflow end 120 than 123, both the inflow recess 111 and the outflow recess 121 are present in the cross section CS1 between the first closed end 113 and the second closed end 123. The fluid (W) that has flowed into the inflow recess 111 from the opening end 112 of the inflow recess 111 enters the activated carbon molded body 100 from the inner side surface 114 of the inflow recess 111, and at least a part of the fluid (W) flows along the cross section CS1 (for example, FIG. It moves to the outflow recess 121 in the directions D3 and D4) shown in 5 and 6, and flows out from the open end 122 of the outflow recess 121. In the activated carbon molded body 100, the fluid (W) is filtered and purified. Since both the inflow recess 111 and the outflow recess 121 are present in the cross section CS1, the pressure loss of the fluid (W) can be reduced and the filtration flow rate can be increased. Therefore, for example, the particles of activated carbon can be made smaller, and the amount of activated carbon in a unit volume can be increased to improve the adsorption performance of activated carbon. Therefore, this aspect can provide a technique capable of miniaturizing a product using an activated carbon molded body.

ここで、活性炭成型体は、活性炭のみからなる成型体でもよいが、活性炭以外の成分が含まれてもよく、活性炭を主成分としてバインダー等といった副成分を含む成型体でもよい。
流体には、水といった液体、及び、空気といった気体が含まれる。本願の「液体」は、溶質が含まれている溶液や、分散質（固体粒子や液体粒子）が含まれている分散系を含む。本願の「気体」は、分散質（固体粒子や液体粒子）が含まれている分散系を含む。
流体は、流入端部から直接、活性炭成型体内に入ってもよいし、側面部から活性炭成型体内に入ってもよい。流体が側面部から活性炭成型体内に入る場合、流入凹部は側面部に開口部を有してもよい。活性炭成型体内の流体は、流出端部から直接、外部へ流出してもよいし、側面部から外部へ流出してもよい。流体が側面部から外部へ出る場合、流出凹部は側面部に開口部を有してもよい。
凹部（流入凹部及び流出凹部）には、後述する態様３の溝、及び、態様３の溝に含まれない凹部（例えば図５に示す流入凹部１１１１）が含まれる。態様３の溝に含まれない凹部には、図５に例示する流入凹部１１１１のような横断面円形の有底穴（閉塞端を有する穴）、横断面楕円形の有底穴、横断面四角形といった横断面多角形の有底穴、等が含まれる。 Here, the activated carbon molded body may be a molded carbon composed of only activated carbon, but may contain components other than activated carbon, or may be a molded carbon containing activated carbon as a main component and containing auxiliary components such as a binder.
Fluids include liquids such as water and gases such as air. The "liquid" of the present application includes a solution containing a solute and a dispersion system containing a dispersoid (solid particles or liquid particles). The "gas" of the present application includes a dispersion system containing dispersoids (solid particles and liquid particles).
The fluid may enter the activated carbon molding body directly from the inflow end portion, or may enter the activated carbon molding body from the side surface portion. If the fluid enters the activated carbon molding from the side surface, the inflow recess may have an opening on the side surface. The fluid in the activated carbon molding body may flow out directly from the outflow end portion to the outside, or may flow out from the side surface portion to the outside. If the fluid exits from the side surface, the outflow recess may have an opening in the side surface.
The recesses (inflow recess and outflow recess) include the groove of the third aspect described later and the recess not included in the groove of the third aspect (for example, the inflow recess 1111 shown in FIG. 5). The recesses not included in the groove of the third aspect include a bottomed hole having a circular cross section (a hole having a closed end) like the inflow recess 1111 illustrated in FIG. 5, a bottomed hole having an elliptical cross section, and a quadrangular cross section. Includes bottomed holes with a polygonal cross section, etc.

［態様２］
図５等に例示するように、前記一以上の流入凹部１１１及び前記一以上の流出凹部１２１の個々の凹部（例えば流入凹部１１１１，１１１２及び流出凹部１２１１，１２１２）のうち前記第一閉塞端１１３と前記第二閉塞端１２３との間の部分Ｐ１における内側面１１４，１２４の面積Ｓinが最も大きい凹部（以下、「最大凹部」ともいう。）における前記面積Ｓinは、前記側面部（例えば外側面１３０）の面積の０．５倍以上でもよい。最大凹部（例えば流出凹部１２１２）の面積Ｓinが活性炭成型体１００の側面部（１３０）の面積の０．５倍以上と大きいことにより、流体（例えば水Ｗ）の圧力損失がさらに低くなり、濾過流量をさらに多くすることができる。従って、本態様は、活性炭成型体を使用した製品をさらに小型化することが可能な技術を提供することができる。 [Aspect 2]
As illustrated in FIG. 5 and the like, of the individual recesses (for example, inflow recesses 1111, 1112 and outflow recesses 1211, 1212) of the one or more inflow recesses 111 and the one or more outflow recesses 121, the first closed end 113 The area Sin in the recess having the largest area Sin of the inner side surfaces 114 and 124 in the portion P1 between the second closed end 123 and the second closed end 123 (hereinafter, also referred to as “maximum recess”) is the side surface portion (for example, the outer surface). It may be 0.5 times or more the area of 130). Since the area Sin of the maximum recess (for example, the outflow recess 1212) is as large as 0.5 times or more the area of the side surface portion (130) of the activated carbon molded body 100, the pressure loss of the fluid (for example, water W) is further reduced, and filtration is performed. The flow rate can be further increased. Therefore, this aspect can provide a technique capable of further miniaturizing a product using an activated carbon molded body.

ここで、活性炭成型体に流入凹部が複数ある場合、個々の流入凹部が最大凹部の候補となる。活性炭成型体に流出凹部が複数ある場合、個々の流出凹部が最大凹部の候補となる。
面積Ｓinが側面部の面積の０．５倍以上である凹部は、流入凹部と流出凹部の両方にあってもよい。 Here, when the activated carbon molded body has a plurality of inflow recesses, each inflow recess is a candidate for the maximum recess. When the activated carbon molded body has a plurality of outflow recesses, each outflow recess is a candidate for the maximum recess.
The recesses having an area Sin of 0.5 times or more the area of the side surface portion may be located in both the inflow recess and the outflow recess.

［態様３］
図５等に例示するように、前記流入凹部１１１と前記流出凹部１２１のうち一方の凹部には、他方の凹部及び前記一方の凹部と交差する横断面ＣＳ１において前記他方の凹部を囲む溝が含まれてもよい。例えば、図５に示す流入凹部１１１２を「他方の凹部」に当てはめると、流入凹部１１１２を囲む流出凹部１２１２が「一方の凹部」に当てはまる。また、流出凹部１２１１を「他方の凹部」に当てはめると、流出凹部１２１１を囲む流入凹部１１１２が「一方の凹部」に当てはまる。「一方の凹部」が「他方の凹部」を囲む溝であることにより、「一方の凹部」の内側面の面積が大きい。
一方の凹部の内側面（１１４又は１２４）の面積が大きいことにより、流体（Ｗ）の圧力損失がさらに低くなり、濾過流量をさらに多くすることができる。従って、本態様は、活性炭成型体を使用した製品をさらに小型化することが可能な技術を提供することができる。
尚、他方の凹部の周りに一方の凹部として溝ではなく図５に示す流入凹部１１１１のような横断面円形又は横断面多角形の流入凹部を複数配置することも可能である。この概念は、態様３には含まれないが、本技術に含まれる。ただ、周りの横断面円形又は横断面多角形の凹部同士を活性炭成型体の強度が確保される間隔にする必要があるため、周りの横断面円形又は横断面多角形の凹部の数に限界があり、当該凹部の内側面の面積を合わせても態様３の溝である場合の「一方の凹部」の内側面の面積に及ばない。このように、態様３では、溝である場合の「一方の凹部」の内側面（１１４又は１２４）の面積が大きくなり、流体（Ｗ）の圧力損失がさらに低くなり、濾過流量がさらに多くなる。 [Aspect 3]
As illustrated in FIG. 5 and the like, one of the inflow recess 111 and the outflow recess 121 includes a groove surrounding the other recess in the cross section CS1 intersecting the other recess and the one recess. It may be. For example, when the inflow recess 1112 shown in FIG. 5 is fitted to the “other recess”, the outflow recess 1212 surrounding the inflow recess 1112 fits into the “one recess”. Further, when the outflow recess 1211 is fitted to the "other recess", the inflow recess 1112 surrounding the outflow recess 1211 fits into the "one recess". Since the "one recess" is a groove surrounding the "other recess", the area of the inner surface of the "one recess" is large.
Since the area of the inner surface (114 or 124) of one of the recesses is large, the pressure loss of the fluid (W) is further reduced, and the filtration flow rate can be further increased. Therefore, this aspect can provide a technique capable of further miniaturizing a product using an activated carbon molded body.
It is also possible to arrange a plurality of inflow recesses having a circular cross section or a polygonal cross section, such as the inflow recess 1111 shown in FIG. 5, instead of a groove as one recess around the other recess. This concept is not included in aspect 3, but is included in the present technology. However, there is a limit to the number of concave portions having a circular cross section or a polygonal cross section around them because the recesses having a circular cross section or a polygonal cross section must be spaced apart from each other to ensure the strength of the activated carbon molded product. Yes, even if the area of the inner surface of the recess is combined, it does not reach the area of the inner surface of the "one recess" in the case of the groove of the third aspect. As described above, in the third aspect, the area of the inner surface (114 or 124) of the “one concave portion” in the case of the groove is increased, the pressure loss of the fluid (W) is further reduced, and the filtration flow rate is further increased. ..

上記溝は、上記凹部の内、深さ（図５に示す例では方向Ｄ１，Ｄ２における長さ）を問わず流入端部や流出端部の表面に沿ってくぼんだ平面視細長いところを意味する。「平面視細長い」とは、平面視において溝の両端が離れている（繋がっていない）形状に限定されず、平面視において環状や四角状といった元に戻る形状、すなわち、両端が閉じている（繋がっている）形状も含む。図５に示す例の場合、溝は、流入凹部１１１１とは異なり、内方向Ｄ３側の内側面と外方向Ｄ４側の内側面との間にある平面視細長状の凹部を意味する。
「一方の凹部」が「他方の凹部」を囲むとは、「他方の凹部」の周りにある「一方の凹部」に隙間が無いことに限定されず、「一方の凹部」が渦巻き状やＣ字形の溝であるといった、「他方の凹部」の周りにある「一方の凹部」に隙間があることも含む。
上述したように、流出凹部を囲む溝である流入凹部と、流入凹部を囲む溝である流出凹部と、の両方が活性炭成型体にあってもよいし、片方のみ活性炭成型体にあってもよい。
上記態様３は、「一方の凹部」が「流入凹部」である場合、「前記一以上の流入凹部には、前記流入凹部及び前記流出凹部と交差する横断面において前記一以上の流出凹部の少なくとも一つを囲む溝が含まれる」と言い換えることができる。また、「一方の凹部」が「流出凹部」である場合、「前記一以上の流出凹部には、前記流入凹部及び前記流出凹部と交差する横断面において前記一以上の流入凹部の少なくとも一つを囲む溝が含まれる」と言い換えることができる。
すなわち、「一方の凹部」としての「流入凹部」が二以上ある場合には少なくとも一つの「流入凹部」が「流出凹部」を囲む溝であれば態様３に含まれ、「一方の凹部」としての「流出凹部」が二以上ある場合には少なくとも一つの「流出凹部」が「流入凹部」を囲む溝であれば態様３に含まれる。
また、具体的には後述するが、他方の凹部を囲む溝の横断面形状には、円形、楕円形、四角形といった多角形、等が含まれる。 The groove means an elongated portion in a plan view that is recessed along the surface of the inflow end portion or the outflow end portion regardless of the depth (the length in directions D1 and D2 in the example shown in FIG. 5) in the recess. .. The term "elongated in plan view" is not limited to a shape in which both ends of the groove are separated (not connected) in a plan view, but a shape that returns to the original shape such as an annular shape or a square shape in a plan view, that is, both ends are closed ( Also includes shapes (which are connected). In the case of the example shown in FIG. 5, the groove means an elongated recess in a plan view between the inner surface on the inward D3 side and the inner surface on the outer D4 side, unlike the inflow recess 1111.
The fact that "one recess" surrounds "the other recess" is not limited to the fact that there is no gap in "one recess" around the "other recess", and "one recess" is spiral or C. It also includes a gap in the "one recess" around the "other recess", such as a glyphic groove.
As described above, both the inflow recess which is the groove surrounding the outflow recess and the outflow recess which is the groove surrounding the inflow recess may be in the activated carbon molded body, or only one of them may be in the activated carbon molded body. ..
In the third aspect, when "one of the recesses" is the "inflow recess", "the one or more inflow recesses have at least one or more outflow recesses in the cross section intersecting the inflow recesses and the outflow recesses. It includes a groove that surrounds one. " When the "one recess" is the "outflow recess", "the one or more outflow recesses include at least one of the inflow recesses and the one or more inflow recesses in the cross section intersecting the outflow recesses. It includes a groove that surrounds it. "
That is, when there are two or more "inflow recesses" as "one recess", if at least one "inflow recess" is a groove surrounding the "outflow recess", it is included in aspect 3 and is referred to as "one recess". When there are two or more "outflow recesses", if at least one "outflow recess" is a groove surrounding the "inflow recess", the third aspect is included.
Further, as will be described in detail later, the cross-sectional shape of the groove surrounding the other recess includes polygons such as a circle, an ellipse, and a quadrangle.

ここで、流通口は、流体が流出する流出口でもよいし、流体が流入する流入口でもよい。流通口部材は、前記流出口と前記流入口の両方を有してもよい。 [Aspect 4]
Further, the filtration cartridge (for example, the water purification cartridge 20) according to one aspect of the present technology includes the activated carbon molded body 100 according to any one of the first to third aspects and the flow port (for example, water W) of the fluid (for example, water W).

In the activated carbon molded body 100 of the filtration cartridge (20) of this embodiment, the pressure loss of the fluid (W) is reduced and the filtration flow rate is increased due to the presence of both the inflow recess 111 and the outflow recess 121 in the cross section CS1. be able to. Therefore, for example, the particles of activated carbon can be made smaller, and the amount of activated carbon in a unit volume can be increased to improve the adsorption performance of activated carbon. Therefore, in this aspect, the filtration cartridge (20) containing the activated carbon molded body 100 can be miniaturized, and the miniaturized filtration cartridge can be provided.
Here, the flow port may be an outflow port through which the fluid flows out, or an inflow port through which the fluid flows in. The distribution port member may have both the outlet and the inlet.

［態様５］
さらに、本技術の一態様に係る浄水器（例えば水栓１）は、活性炭ＡＣ１を含む活性炭成型体１００を有する浄水カートリッジ２０、及び、該浄水カートリッジ２０を収容する浄水器本体（例えば吐水ヘッド１０）を備える。この浄水器本体（１０）は、水入口（例えばホース１９）及び水出口１３を有する。前記活性炭成型体１００は、水Ｗが流入する一以上の流入凹部１１１の開口端１１２が配置された流入端部１１０と、前記水Ｗが流出する一以上の流出凹部１２１の開口端１２２が配置された流出端部１２０と、前記流入端部１１０から前記流出端部１２０に繋がる側面部（例えば外側面１３０）と、を有する。前記流入凹部１１１は、前記流出端部１２０側の端部に閉塞した第一閉塞端１１３を有する。前記流出凹部１２１は、前記流入端部１１０側の端部に閉塞した第二閉塞端１２３を有する。前記第一閉塞端１１３は、前記第二閉塞端１２３よりも前記流出端部１２０側にある。本浄水器（１）は、前記水入口（１９）から流入した前記水Ｗが前記流入凹部１１１に入り、前記流出凹部１２１から出た前記水Ｗが前記水出口１３から流出する。 [Aspect 5]
Further, the water purifier (for example, faucet 1) according to one aspect of the present technology includes a water purification cartridge 20 having an activated carbon molded body 100 containing activated carbon AC1 and a water purifier main body (for example, a water discharge head 10) accommodating the water purification cartridge 20. ) Is provided. The water purifier main body (10) has a water inlet (for example, a hose 19) and a water outlet 13. The activated carbon molded body 100 has an inflow end 110 in which the opening ends 112 of one or more inflow recesses 111 into which water W flows in are arranged, and an opening end 122 of one or more outflow recesses 121 in which the water W flows out. It has an outflow end portion 120 and a side surface portion (for example, an outer surface 130) connected from the inflow end portion 110 to the outflow end portion 120. The inflow recess 111 has a first closed end 113 closed at the end on the outflow end 120 side. The outflow recess 121 has a second closed end 123 that is closed at the end on the inflow end 110 side. The first closed end 113 is closer to the outflow end portion 120 than the second closed end 123. In the water purifier (1), the water W flowing in from the water inlet (19) enters the inflow recess 111, and the water W discharged from the outflow recess 121 flows out from the water outlet 13.

上記態様５において、流入凹部１１１の開口端１１２から流入凹部１１１に流入した水Ｗは、流入凹部１１１の内側面１１４から活性炭成型体１００内に入り、少なくとも一部が横断面ＣＳ１に沿った方向（例えば図５，６に示す方向Ｄ３，Ｄ４）にある流出凹部１２１へ移動して流出凹部１２１の開口端１２２から外部へ流出する。活性炭成型体１００内において、水Ｗが濾過されて浄化される。横断面ＣＳ１において流入凹部１１１と流出凹部１２１の両方が存在することにより、水Ｗの圧力損失が低くなり、濾過流量を多くすることができる。このため、例えば、活性炭の粒子を小さくすることができ、単位体積における活性炭量を増やして活性炭の吸着性能を向上させることができる。従って、本態様は、活性炭成型体１００を収容した浄水器（１）を小型化することができ、小型化された浄水器を提供することができる。 In the above aspect 5, the water W flowing into the inflow recess 111 from the opening end 112 of the inflow recess 111 enters the activated carbon molded body 100 from the inner side surface 114 of the inflow recess 111, and at least a part thereof is in the direction along the cross section CS1. It moves to the outflow recess 121 in (for example, directions D3 and D4 shown in FIGS. 5 and 6) and flows out from the opening end 122 of the outflow recess 121. Water W is filtered and purified in the activated carbon molded body 100. Since both the inflow recess 111 and the outflow recess 121 are present in the cross section CS1, the pressure loss of the water W can be reduced and the filtration flow rate can be increased. Therefore, for example, the particles of activated carbon can be made smaller, and the amount of activated carbon in a unit volume can be increased to improve the adsorption performance of activated carbon. Therefore, in this aspect, the water purifier (1) accommodating the activated carbon molded body 100 can be miniaturized, and a miniaturized water purifier can be provided.

（２）濾過カートリッジを有する浄水器の具体例：
図１は、浄水機能付き水栓１（浄水器の例）を組み込んだシステムキッチンＳＹ１を模式的に例示している。この例の浄水器は、いわゆるスパウトイン浄水器であり、浄水カートリッジ２０（濾過カートリッジの例）により浄水機能を発揮する。尚、各部の位置関係の説明は、例示に過ぎない。従って、左右方向を上下方向又は前後方向に変更したり、上下方向を左右方向や前後方向に変更したり、前後方向を左右方向や上下方向に変更したり、回転方向を逆方向に変更したり等することも、本技術に含まれる。また、方向や位置等の同一は、厳密な一致に限定されず、誤差により厳密な一致からずれることを含む。 (2) Specific example of a water purifier having a filtration cartridge:
FIG. 1 schematically illustrates a system kitchen SY1 incorporating a faucet 1 with a water purification function (an example of a water purifier). The water purifier of this example is a so-called spout-in water purifier, and the water purification cartridge 20 (example of a filtration cartridge) exerts a water purification function. The explanation of the positional relationship of each part is merely an example. Therefore, the left-right direction can be changed to the up-down direction or the front-back direction, the up-down direction can be changed to the left-right direction or the front-back direction, the front-back direction can be changed to the left-right direction or the up-down direction, or the rotation direction can be changed to the opposite direction. Etc. are also included in this technology. In addition, the same direction, position, etc. are not limited to exact matching, and include deviation from exact matching due to an error.

図１に示すシステムキッチンＳＹ１には、水平に延びるカウンター８０１にキャビネット８０２、凹状のシンク８０３、水栓１、等が組み込まれている。水栓１は、カウンター８０１の下面に配置されたシンク８０３を上下に貫通して取付けられた水栓本体２、この水栓本体２に対して着脱可能な吐水ヘッド（浄水器本体の例）１０、水栓本体２に対して傾動可能な開栓レバー３、等を備えている。尚、本具体例の浄水器本体は、浄水カートリッジ２０を除いた吐水ヘッド１０を意味する。吐水ヘッド１０には、水栓本体２に通されているホース１９（水入口の例）が接続されている。ホース１９は、開栓レバー３が開いている時に図示しない給水管からの水道水を吐水ヘッド１０に供給する。水栓本体２から吐水ヘッド１０が取り外されると、水栓本体２からホース１９が引き出される。水栓本体２に吐水ヘッド１０を取り付ける時には、水栓本体２にホース１９が引き込まれる。開栓レバー３は、開位置（例えば傾動範囲の上側の位置）にある時にホース１９を介して吐水ヘッド１０へ水道水が供給されるようにし、閉位置（例えば傾動範囲の下側の位置）にある時に吐水ヘッド１０への水道水の供給を停止させる。 In the system kitchen SY1 shown in FIG. 1, a cabinet 802, a concave sink 803, a faucet 1, and the like are incorporated in a horizontally extending counter 801. The faucet 1 is a faucet main body 2 attached by penetrating the sink 803 arranged on the lower surface of the counter 801 up and down, and a water discharge head (example of a water purifier main body) 10 that can be attached to and detached from the faucet main body 2. , An opening lever 3 that can be tilted with respect to the faucet main body 2, and the like. The water purifier main body of this specific example means a water discharge head 10 excluding the water purification cartridge 20. A hose 19 (example of a water inlet) passing through the faucet main body 2 is connected to the water discharge head 10. The hose 19 supplies tap water from a water supply pipe (not shown) to the water discharge head 10 when the opening lever 3 is open. When the water discharge head 10 is removed from the faucet main body 2, the hose 19 is pulled out from the faucet main body 2. When the water discharge head 10 is attached to the faucet body 2, the hose 19 is pulled into the faucet body 2. The opening lever 3 allows tap water to be supplied to the water discharge head 10 via the hose 19 when it is in the open position (for example, the position above the tilt range), and the closed position (for example, the position below the tilt range). The supply of tap water to the spout head 10 is stopped at the time of.

図２（ａ）は、浄水カートリッジ２０を取り付けた吐水ヘッド１０を一部断面視して例示している。図２（ｂ）は、浄水カートリッジ２０を取り付けた吐水部を例示している。図２に示す吐水ヘッド１０は、先端側、すなわち、水の流下方向Ｄ１の下流側にある吐水部１１、及び、水栓本体２に対して着脱される把持部１８を有し、交換部品である浄水カートリッジ２０が組み込まれている。吐水ヘッド１０の内側において浄水カートリッジ２０の外側は、水道水が流れる水道水通路１０ａとされている。吐水部１１には、浄水カートリッジ２０との接続口１２、及び、接続口１２からの浄水を出すか水道水通路１０ａからの水道水を出すかの切替操作可能な切替レバー１５が設けられている。切替レバー１５は、浄水側（例えば回転範囲の一端側）にある時に水道水を止めて浄水を吐水部１１の水出口１３から吐出させ、水道水側（例えば回転範囲の他端側）にある時浄水を止めて水道水を吐水部１１の水出口１３から吐出させる。 FIG. 2A exemplifies a partial cross-sectional view of the water discharge head 10 to which the water purification cartridge 20 is attached. FIG. 2B illustrates a water discharge portion to which the water purification cartridge 20 is attached. The water discharge head 10 shown in FIG. 2 has a water discharge portion 11 on the tip side, that is, a downstream side in the water flow direction D1, and a grip portion 18 attached to and detached from the faucet body 2, and is a replacement part. A water purification cartridge 20 is incorporated. Inside the water discharge head 10, the outside of the water purification cartridge 20 is a tap water passage 10a through which tap water flows. The water discharge unit 11 is provided with a connection port 12 for connecting to the water purification cartridge 20 and a switching lever 15 capable of switching between discharging purified water from the connection port 12 and tap water from the tap water passage 10a. .. The switching lever 15 stops tap water when it is on the purified water side (for example, one end side of the rotation range), discharges purified water from the water outlet 13 of the water discharge unit 11, and is on the tap water side (for example, the other end side of the rotation range). When the water purification is stopped, tap water is discharged from the water outlet 13 of the water discharge unit 11.

図２に示すように、吐水部１１の上流側における端部の外周に雄ねじ１１ａが形成され、把持部１８の下流側における端部の内周に雌ねじ１８ａが形成されている。両ねじ１１ａ，１８ａを螺合することにより把持部１８を吐水部１１に取り付けることができ、雄ねじ１１ａから雌ねじ１８ａを外すことにより吐水部１１から把持部１８を取り外すことができる。 As shown in FIG. 2, a male screw 11a is formed on the outer circumference of the end portion on the upstream side of the water discharge portion 11, and a female screw 18a is formed on the inner circumference of the end portion on the downstream side of the grip portion 18. The grip portion 18 can be attached to the water discharge portion 11 by screwing both screws 11a and 18a, and the grip portion 18 can be removed from the water discharge portion 11 by removing the female screw 18a from the male screw 11a.

水栓本体２に収容される交換可能な浄水カートリッジ２０は、活性炭成型体１００を含む吸着剤部３０、及び、中空糸膜Ｈ１を複数束ねた中空糸膜束ＢＨ１の収容部７１を有する中空糸膜ケース７０（流通口部材の例）を備えている。吸着剤部３０は流下方向Ｄ１の上流側に配置され、中空糸膜ケース７０は流下方向Ｄ１の下流側に配置されている。浄水カートリッジ２０に流入した水道水は、吸着剤部３０、中空糸膜束収容部７１、の順に入り、浄化される。 The replaceable water purification cartridge 20 housed in the faucet body 2 is a hollow fiber having an adsorbent part 30 including an activated carbon molded body 100 and a hollow fiber membrane bundle BH1 accommodating part 71 in which a plurality of hollow fiber membranes H1 are bundled. A membrane case 70 (an example of a distribution port member) is provided. The adsorbent portion 30 is arranged on the upstream side of the flow direction D1, and the hollow fiber membrane case 70 is arranged on the downstream side of the flow direction D1. The tap water that has flowed into the water purification cartridge 20 enters the adsorbent portion 30 and the hollow fiber membrane bundle accommodating portion 71 in this order to be purified.

中空糸膜束収容部７１は、吐水部１１に対して流下方向Ｄ１へ挿入されて取り付けられる。この時、中空糸膜束収容部７１の流出口７５（流通口の例）が吐水部１１の接続口１２に挿入される。浄水カートリッジ２０は、吸着剤部３０、及び、中空糸膜ケース７０の外嵌部８０が吐水部１１から出た状態で吐水部１１に固定される。浄水カートリッジ２０は、吐水部１１から流下方向Ｄ１とは反対の方向（延出方向Ｄ２）へ引き出すことにより取り外される。従って、浄水カートリッジ２０は、吐水ヘッド１０に対して着脱可能である。 The hollow fiber membrane bundle accommodating portion 71 is inserted and attached to the water discharge portion 11 in the flow direction D1. At this time, the outlet 75 (example of the distribution port) of the hollow fiber membrane bundle accommodating portion 71 is inserted into the connection port 12 of the water discharge portion 11. The water purification cartridge 20 is fixed to the water discharge portion 11 with the adsorbent portion 30 and the outer fitting portion 80 of the hollow fiber membrane case 70 protruding from the water discharge portion 11. The water purification cartridge 20 is removed by pulling it out from the water discharge portion 11 in the direction opposite to the flow direction D1 (extending direction D2). Therefore, the water purification cartridge 20 is removable from the water discharge head 10.

図３は、浄水カートリッジ２０の中心軸ＡＸ１を通る縦断面を例示している。図４は、浄水カートリッジ２０を分解して例示している。図５は、吸着剤部３０の活性炭成型体１００の中心軸ＡＸ１を通る縦断面、流入端部１１０（右上の二点鎖線の囲み内）、及び、流出端部１２０（右下の二点鎖線の囲み内）を例示している。図６は、活性炭成型体１００の要部を模式的に例示している。
図６に示すように、活性炭成型体１００は、活性炭ＡＣ１を含んでいる。活性炭成型体１００は、活性炭ＡＣ１のみからなる成型体でもよいが、活性炭ＡＣ１を主成分としてバインダーＢ１やイオン交換体等といった副成分を含む成型体でもよい。吸着剤部３０は、活性炭成型体１００のみからなる部位でもよいが、不織布３１等といった材料を有してもよい。図３，４に示す吸着剤部３０は、活性炭成型体１００の外側面１３０（側面部の例）をほぼ覆う円筒状の不織布３１を有している。不織布３１は、浄水カートリッジ２０を交換する際に活性炭成型体１００が手に触れないようにする役割を有する。不織布３１は水中の微粒子を除去しながら水Ｗ（流体の例）を通すので、外側面１３０から活性炭成型体１００の内部に水Ｗが入る。不織布３１には、ポリエチレン（ＰＥ）繊維やポリプロピレン（ＰＰ）繊維といったポリオレフィン繊維、ポリエステル繊維、ポリアミド繊維、ポリビニルアルコール繊維、これらの組合せ、といった熱可塑性樹脂（合成樹脂）の繊維等を用いることができる。 FIG. 3 illustrates a vertical cross section of the water purification cartridge 20 passing through the central axis AX1. FIG. 4 illustrates the disassembled water purification cartridge 20. FIG. 5 shows a vertical cross section of the adsorbent portion 30 passing through the central axis AX1 of the activated carbon molded body 100, an inflow end 110 (inside the upper right two-dot chain line), and an outflow end 120 (lower right two-dot chain line). (Inside the box) is illustrated. FIG. 6 schematically illustrates a main part of the activated carbon molded body 100.
As shown in FIG. 6, the activated carbon molded body 100 contains the activated carbon AC1. The activated carbon molded body 100 may be a molded carbon composed of only activated carbon AC1, but may be a molded carbon containing activated carbon AC1 as a main component and containing auxiliary components such as a binder B1 and an ion exchanger. The adsorbent portion 30 may be a portion made of only the activated carbon molded body 100, or may have a material such as a non-woven fabric 31 or the like. The adsorbent portion 30 shown in FIGS. 3 and 4 has a cylindrical non-woven fabric 31 that substantially covers the outer surface 130 (example of the side surface portion) of the activated carbon molded body 100. The non-woven fabric 31 has a role of preventing the activated carbon molded body 100 from touching the hand when the water purification cartridge 20 is replaced. Since the non-woven fabric 31 passes water W (example of a fluid) while removing fine particles in water, water W enters the inside of the activated carbon molded body 100 from the outer surface 130. As the non-woven fabric 31, polyolefin fibers such as polyethylene (PE) fibers and polypropylene (PP) fibers, polyester fibers, polyamide fibers, polyvinyl alcohol fibers, and thermoplastic resin (synthetic resin) fibers such as a combination thereof can be used. ..

図２〜４に示すように、中空糸膜ケース７０は、内部空間７０ｃとなる凹部に中空糸膜束ＢＨ１が固定された本体部７０ａと、流出口７５を有する蓋部７０ｂとを嵌め合わせた構造を有している。この構造を有する中空糸膜ケース７０は、内部空間７０ｃに中空糸膜束ＢＨ１が収容された収容部７１、及び、吸着剤部３０の流下方向Ｄ１における端部３０ｂの外嵌部８０が形成されている。収容部７１には、中空糸膜束ＢＨ１の閉塞端部ＢＨ１ａに対向する連絡口７４、及び、中空糸膜束ＢＨ１の開口端部ＢＨ１ｂに対向する流出口７５が形成されている。外嵌部８０は、連絡口７４の外側において中空糸膜束収容部７１から吸着剤部３０側（延出方向Ｄ２）へ延出し、吸着剤部３０の下流側の端部３０ｂが挿入される。外嵌部８０に吸着剤部３０の端部３０ｂを入れてホットメルト等といった接着剤で固定すると、吸着剤部３０が中空糸膜ケース７０に保持される。尚、外嵌部８０と吸着剤部３０との固定手段は、接着剤に限定されず、Ｏリング等といったシール部材でもよい。中空糸膜ケース７０には、ＡＢＳ樹脂、ＡＳ樹脂、ＰＥ樹脂やＰＰ樹脂といったポリオレフィン樹脂、ＰＳ樹脂、フッ素樹脂、これらの組合せ、といった熱可塑性樹脂（合成樹脂）等を用いることができる。 As shown in FIGS. 2 to 4, in the hollow fiber membrane case 70, a main body portion 70a in which the hollow fiber membrane bundle BH1 is fixed in a concave portion serving as an internal space 70c and a lid portion 70b having an outlet 75 are fitted together. It has a structure. In the hollow fiber membrane case 70 having this structure, an accommodating portion 71 in which the hollow fiber membrane bundle BH1 is accommodated is formed in the internal space 70c, and an outer fitting portion 80 of the end portion 30b in the flow direction D1 of the adsorbent portion 30 is formed. ing. The accommodating portion 71 is formed with a contact port 74 facing the closed end portion BH1a of the hollow fiber membrane bundle BH1 and an outlet 75 facing the open end portion BH1b of the hollow fiber membrane bundle BH1. The outer fitting portion 80 extends from the hollow fiber membrane bundle accommodating portion 71 to the adsorbent portion 30 side (extending direction D2) on the outside of the communication port 74, and the end portion 30b on the downstream side of the adsorbent portion 30 is inserted. .. When the end portion 30b of the adsorbent portion 30 is put into the outer fitting portion 80 and fixed with an adhesive such as hot melt, the adsorbent portion 30 is held by the hollow fiber membrane case 70.

図３〜５に示す活性炭成型体１００は、凹部１１１，１２１を有する略円柱状であり、水Ｗが流入する上流側に略円形の流入端部１１０を向け、水Ｗが流出する下流側に略円形の流出端部１２０を向けて、水栓本体２に配置される。活性炭成型体１００の外側面１３０は、横断面略円形であり、流入端部１１０から流出端部１２０に繋がっている。尚、活性炭成型体１００の脱型を考慮して、活性炭成型体１００を僅かにテーパー状にしてもよい。 The activated carbon molded body 100 shown in FIGS. 3 to 5 has a substantially columnar shape having recesses 111 and 121, and the substantially circular inflow end 110 is directed to the upstream side where the water W flows in, and the downstream side where the water W flows out. The faucet body 2 is arranged with the substantially circular outflow end 120 facing. The outer surface 130 of the activated carbon molded body 100 has a substantially circular cross section, and is connected from the inflow end 110 to the outflow end 120. In consideration of the demolding of the activated carbon molded body 100, the activated carbon molded body 100 may be slightly tapered.

流入端部１１０には、水Ｗが流入する流入凹部１１１の開口端１１２が配置されている。流入凹部１１１は、活性炭成型体１００を含む浄水カートリッジ２０の中心軸ＡＸ１に沿って開口端１１２から流出端部１２０近くの第一閉塞端１１３まで延びている。第一閉塞端１１３は、流入凹部１１１における流出端部１２０側の閉塞した端部である。流出端部１２０には、水Ｗが流出する流出凹部１２１の開口端１２２が配置されている。流出凹部１２１は、中心軸ＡＸ１に沿って開口端１２２から流入端部１１０近くの第二閉塞端１２３まで延びている。第二閉塞端１２３は、流出凹部１２１における流入端部１１０側の閉塞した端部である。本具体例の活性炭成型体１００は、中心軸ＡＸ１に沿った方向（Ｄ１，Ｄ２）において、流入凹部１１１の第一閉塞端１１３が流出凹部１２１の第二閉塞端１２３よりも流出端部１２０側にあるという特徴を有する。これにより、図５，６に示すように、開口端１１２から流入凹部１１１に流入した水Ｗの少なくとも一部が中心軸ＡＸ１と直交する横断面ＣＳ１に沿った方向（Ｄ３，Ｄ４）にある流出凹部１２１へ移動して開口端１２２から外部へ流出する。その際、水Ｗが濾過されて浄化される。尚、流入凹部１１１から流出凹部１２１への水Ｗの移動は、隙間１０５を通る移動であり、厳密に中心軸ＡＸ１と直交する方向（Ｄ３，Ｄ４）へ直進する移動に限定されない。 An opening end 112 of an inflow recess 111 into which water W flows is arranged at the inflow end 110. The inflow recess 111 extends from the opening end 112 to the first closed end 113 near the outflow end 120 along the central axis AX1 of the water purification cartridge 20 containing the activated carbon molded body 100. The first closed end 113 is a closed end of the inflow recess 111 on the outflow end 120 side. The open end 122 of the outflow recess 121 from which the water W flows out is arranged at the outflow end 120. The outflow recess 121 extends from the opening end 122 along the central axis AX1 to the second closed end 123 near the inflow end 110. The second closed end 123 is a closed end of the outflow recess 121 on the inflow end 110 side. In the activated carbon molded body 100 of this specific example, the first closed end 113 of the inflow recess 111 is closer to the outflow end 120 than the second closed end 123 of the outflow recess 121 in the directions (D1, D2) along the central axis AX1. It has the characteristic of being in. As a result, as shown in FIGS. 5 and 6, at least a part of the water W flowing into the inflow recess 111 from the opening end 112 flows out in the direction (D3, D4) along the cross section CS1 orthogonal to the central axis AX1. It moves to the recess 121 and flows out from the opening end 122 to the outside. At that time, the water W is filtered and purified. The movement of the water W from the inflow recess 111 to the outflow recess 121 is a movement through the gap 105, and is not limited to a movement that goes straight in the direction (D3, D4) strictly orthogonal to the central axis AX1.

ここで、中心軸ＡＸ１と直交する横断面ＣＳ１が軸ＡＸ１に沿った方向（Ｄ１，Ｄ２）において第一閉塞端１１３と第二閉塞端１２３との間の部分Ｐ１にあるものとする。この場合、横断面ＣＳ１は、凹部１１１，１２１の全てと交差する。図５に示す活性炭成型体１００は、凹部１１１，１２１として、中心軸ＡＸ１から外方向Ｄ４へ順に、流入凹部１１１１、横断面ＣＳ１において流入凹部１１１１を囲む環状の流出凹部１２１１、横断面ＣＳ１において流出凹部１２１１を囲む環状の流入凹部１１１２、及び、横断面ＣＳ１において流入凹部１１１２を囲む環状の流出凹部１２１２を有している。図５に示す凹部１２１１，１１１２，１２１２の横断面形状は、円形である。凹部１１１１，１２１１，１１１２，１２１２は、軸ＡＸ１を中心とする同心円状に配置され、軸ＡＸ１を含む縦断面において略平行に配置されている。尚、流入凹部１１１は流入凹部１１１１，１１１２を総称し、流出凹部１２１は流出凹部１２１１，１２１２を総称する。 Here, it is assumed that the cross section CS1 orthogonal to the central axis AX1 is located in the portion P1 between the first closed end 113 and the second closed end 123 in the directions (D1, D2) along the axis AX1. In this case, the cross section CS1 intersects all of the recesses 111 and 121. The activated carbon molded body 100 shown in FIG. 5 has recesses 111 and 121, which flow out in the inflow recess 1111 in the outward direction D4 from the central axis AX1, the annular outflow recess 1211 surrounding the inflow recess 1111 in the cross section CS1, and the cross section CS1. It has an annular inflow recess 1112 that surrounds the recess 1211 and an annular outflow recess 1212 that surrounds the inflow recess 1112 in the cross section CS1. The cross-sectional shape of the recesses 1211, 1112, 1212 shown in FIG. 5 is circular. The recesses 1111, 1211, 1112, 1212 are arranged concentrically with the axis AX1 as the center, and are arranged substantially parallel in the vertical cross section including the axis AX1. The inflow recess 111 is a general term for the inflow recesses 1111, 1112, and the outflow recess 121 is a general term for the outflow recesses 1211, 1212.

図５に示す例では、中心にある流入凹部１１１１を上記態様３の「他方の凹部」に当てはめると、流出凹部１２１１，１２１２が「一方の凹部」に当てはまる。流出凹部１２１１を上記態様３の「他方の凹部」に当てはめると、流入凹部１１１２が「一方の凹部」に当てはまる。流入凹部１１１２を上記態様３の「他方の凹部」に当てはめると、流出凹部１２１２が「一方の凹部」に当てはまる。 In the example shown in FIG. 5, when the inflow recess 1111 in the center is fitted to the “other recess” of the above aspect 3, the outflow recesss 1211 and 1212 are fitted to the “one recess”. When the outflow recess 1211 is fitted to the "other recess" of the above aspect 3, the inflow recess 1112 fits into the "one recess". When the inflow recess 1112 is fitted to the "other recess" of the above aspect 3, the outflow recess 1212 fits into the "one recess".

図５，６に示すように、中心にある流入凹部１１１１に流入した水Ｗは、この流入凹部１１１１の内側面１１４から隙間１０５を通って外方向Ｄ４にある平面視環状溝の流出凹部１２１１へ移動する。平面視環状溝である流入凹部１１１２に流入した水Ｗは、この流入凹部１１１２の内側面１１４から隙間１０５を通って内方向Ｄ３にある平面視環状溝の流出凹部１２１１と外方向Ｄ４にある平面視環状溝の流出凹部１２１２へ移動する。活性炭成型体１００の外側面１３０に流入した水Ｗは、隙間１０５を通って内方向Ｄ３にある平面視環状溝の流出凹部１２１２へ移動する。 As shown in FIGS. 5 and 6, the water W flowing into the central inflow recess 1111 passes through the gap 105 from the inner side surface 114 of the inflow recess 1111 to the outflow recess 1211 of the annular groove in the plan view in the outward direction D4. Moving. The water W that has flowed into the inflow recess 1112, which is the annular groove in the plan view, passes through the gap 105 from the inner side surface 114 of the inflow recess 1112 and passes through the gap 105 to the outflow recess 1211 of the annular groove in the plan view and the plane in the outer direction D4. It moves to the outflow recess 1212 of the annular groove. The water W that has flowed into the outer surface 130 of the activated carbon molded body 100 moves through the gap 105 to the outflow recess 1212 of the annular groove in the plan view in the inward direction D3.

ここで、中心軸ＡＸ１に沿った方向（Ｄ１，Ｄ２）における第一閉塞端１１３と第二閉塞端１２３との距離をＬとする。第一閉塞端１１３と第二閉塞端１２３との間の部分Ｐ１における活性炭成型体１００の外側面１３０の面積Ｓoutは、以下の通りとなる。
Ｓout＝Ｌ×π×２×ｒｏｕｔ
ただし、ｒｏｕｔは、中心軸ＡＸ１を基準とした外側面１３０の半径である。 Here, let L be the distance between the first closed end 113 and the second closed end 123 in the directions (D1, D2) along the central axis AX1. The area Sout of the outer surface 130 of the activated carbon molded body 100 in the portion P1 between the first closed end 113 and the second closed end 123 is as follows.
Sout = L × π × 2 × out
However, runout is the radius of the outer surface 130 with respect to the central axis AX1.

閉塞端１１３，１２３の間の部分Ｐ１における各凹部１１１１，１２１１，１１１２，１２１２の内側面（図６に示す内側面１１４又は１２４）の面積Ｓin、及び、面積比Ｓin／Ｓoutは、以下の通りとなる。
（流入凹部１１１１の内側面１１４の場合）
Ｓin＝Ｌ×π×Ｒｉ
ただし、Ｒｉは流入凹部１１１１の直径である。
Ｓin／Ｓout＝（Ｒｉ／２）／ｒｏｕｔ
（流出凹部１２１１の内側面１２４の場合）
Ｓin＝Ｌ×（π×２×ｒｏ１＋π×２×ｒｏ２）
ただし、ｒｏ１は流出凹部１２１１の内側面１２４における内側の中心軸ＡＸ１を基準とした半径であり、ｒｏ２は流出凹部１２１１の内側面１２４における外側の中心軸ＡＸ１を基準とした半径である。
Ｓin／Ｓout＝（ｒｏ１＋ｒｏ２）／ｒｏｕｔ
（流入凹部１１１２の内側面１１４の場合）
Ｓin＝Ｌ×（π×２×ｒｉ１＋π×２×ｒｉ２）
ただし、ｒｉ１は流入凹部１１１２の内側面１１４における内側の中心軸ＡＸ１を基準とした半径であり、ｒｉ２は流入凹部１１１２の内側面１１４における外側の中心軸ＡＸ１を基準とした半径である。
Ｓin／Ｓout＝（ｒｉ１＋ｒｉ２）／ｒｏｕｔ
（流出凹部１２１２の内側面１２４の場合）
Ｓin＝Ｌ×（π×２×ｒｏ３＋π×２×ｒｏ４）
ただし、ｒｏ３は流出凹部１２１２の内側面１２４における内側の中心軸ＡＸ１を基準とした半径であり、ｒｏ４は流出凹部１２１２の内側面１２４における外側の中心軸ＡＸ１を基準とした半径である。
Ｓin／Ｓout＝（ｒｏ３＋ｒｏ４）／ｒｏｕｔ The area Sin and the area ratio Sin / Sout of the inner side surface (inner side surface 114 or 124 shown in FIG. 6) of each recess 1111, 1211, 1112, 1212 in the portion P1 between the closed ends 113 and 123 are as follows. It becomes.
(In the case of the inner surface 114 of the inflow recess 1111)
Sin = L × π × Ri
However, Ri is the diameter of the inflow recess 1111.
Sin / Sout = (Ri / 2) / runout
(In the case of the inner side surface 124 of the outflow recess 1211)
Sin = L × (π × 2 × ro1 + π × 2 × ro2)
However, ro1 is a radius based on the inner central axis AX1 on the inner side surface 124 of the outflow recess 1211, and ro2 is a radius based on the outer central axis AX1 on the inner side surface 124 of the outflow recess 1211.
Sin / Sout = (ro1 + ro2) / runout
(In the case of the inner side surface 114 of the inflow recess 1112)
Sin = L × (π × 2 × ri1 + π × 2 × ri2)
However, ri1 is a radius based on the inner central axis AX1 on the inner side surface 114 of the inflow recess 1112, and ri2 is a radius based on the outer central axis AX1 on the inner side surface 114 of the inflow recess 1112.
Sin / Sout = (ri1 + ri2) / runout
(In the case of the inner side surface 124 of the outflow recess 1212)
Sin = L × (π × 2 × ro3 + π × 2 × ro4)
However, ro3 is a radius based on the inner central axis AX1 on the inner side surface 124 of the outflow recess 1212, and ro4 is a radius based on the outer central axis AX1 on the inner side surface 124 of the outflow recess 1212.
Sin / Sout = (ro3 + ro4) / runout

流入凹部１１１１のように単純な断面円形の流入凹部及び流出凹部を略円柱状の活性炭成型体に設ける場合であって、流入凹部と流出凹部とが同じ直径である場合、流入凹部及び流出凹部の直径は活性炭成型体の直径の０．５倍未満となる。従って、最も大きい凹部の内側面の面積は、活性炭成型体の外側面の面積の０．５倍未満（Ｓin／Ｓout＜０．５）となる。 When the inflow recess and the outflow recess having a simple circular cross section are provided in the activated carbon molded body having a substantially columnar shape as in the inflow recess 1111 and the inflow recess and the outflow recess have the same diameter, the inflow recess and the outflow recess The diameter is less than 0.5 times the diameter of the activated carbon molded body. Therefore, the area of the inner surface of the largest recess is less than 0.5 times the area of the outer surface of the activated carbon molded body (Sin / Sout <0.5).

本具体例のように凹部１１１，１２１を環状溝にすると、内側面１１４，１２４における内側の半径が活性炭成型体１００の外側面１３０の半径の１／４以上あればＳin／Ｓout＞０．５となる。例えば、流入凹部１１１２の内側面１１４における内側の半径ｒｉ１はｒｏｕｔ／４よりも遥かに大きいため、流入凹部１１１２の内側面１１４の面積Ｓinは、活性炭成型体１００の外側面１３０の面積Ｓoutの０．５倍よりも遥かに大きくなる。実際には、（ｒｉ１＋ｒｉ２）／２がｒｏｕｔ／２程度であるため、面積比Ｓin／Ｓoutは１程度となる。また、流出凹部１２１２の内側面１２４の場合、（ｒｏ３＋ｒｏ４）／２が（３／４）×ｒｏｕｔ程度であるため、面積比Ｓin／Ｓoutは１．５程度となる。 When the recesses 111 and 121 are made into annular grooves as in this specific example, if the inner radius of the inner side surfaces 114 and 124 is 1/4 or more of the radius of the outer surface 130 of the activated carbon molded body 100, Sin / Sout> 0.5. It becomes. For example, since the inner radius ri1 of the inner surface 114 of the inflow recess 1112 is much larger than that of runout / 4, the area Sin of the inner surface 114 of the inflow recess 1112 is 0 of the area Sout of the outer surface 130 of the activated carbon molded body 100. Much larger than .5 times. Actually, since (ri1 + ri2) / 2 is about round / 2, the area ratio Sin / Sout is about 1. Further, in the case of the inner side surface 124 of the outflow recess 1212, since (ro3 + ro4) / 2 is about (3/4) × roout, the area ratio Sin / Sout is about 1.5.

水Ｗの圧力損失を低くして活性炭成型体１００の濾過流量を多くする点から、面積比Ｓin／Ｓoutは、０．５以上が好ましく、０．６以上がより好ましく、０．７以上がさらに好ましい。凹部１１１，１２１が環状溝である場合、活性炭成型体１００の強度を向上させる点から、面積比Ｓin／Ｓoutは、１．９以下が好ましく、１．８以下がより好ましく、１．７以下がさらに好ましい。 The area ratio Sin / Sout is preferably 0.5 or more, more preferably 0.6 or more, and further 0.7 or more, from the viewpoint of lowering the pressure loss of water W and increasing the filtration flow rate of the activated carbon molded body 100. preferable. When the recesses 111 and 121 are annular grooves, the area ratio Sin / Sout is preferably 1.9 or less, more preferably 1.8 or less, and 1.7 or less, from the viewpoint of improving the strength of the activated carbon molded body 100. More preferred.

図５に示す活性炭成型体１００の場合、面積Ｓinが最も大きい最大凹部は流出凹部１２１２である。この最大凹部の内側面の面積Ｓinが活性炭成型体１００の外側面１３０の面積Ｓoutの０．５倍以上と大きいことにより、水Ｗの圧力損失をさらに低くすることができ、濾過流量をさらに多くすることができる。このため、活性炭が粒子状である場合は活性炭の粒子を小さくすることができ、単位体積における活性炭量を増やして活性炭の吸着性能を向上させることができる。
尚、流入凹部１１１の内側面１１４の面積ＳinがＳin／Ｓout≧０．５と大きい場合、水Ｗの圧力損失が低いうえ、内側面１１４が目詰まりし難くなり、活性炭成型体１００の寿命が長くなる。
以上説明したように、環状の「一方の凹部」が環状の「他方の凹部」を囲むためには、平面視において「一方の凹部」が「他方の凹部」よりも周長を大きくする必要がある。これは、「一方の凹部」の内側面の面積Ｓinを大きくする。流入凹部１１１１のような断面円形の穴を複数配置して「他方の凹部」を囲む場合、活性炭成型体の強度確保のために肉厚（図６のＴａに相当）を確保する必要があるので、穴の数に限界があり、これらの穴の内側面の面積を合わせても環状溝の内側面の面積よりも遥かに小さくなる。環状溝といった「一方の凹部」が「他方の凹部」を囲む閉じた溝である場合、内側の内側面と外側の内側面とが連続しているので、内側面の面積を大きくするのに好適である。
また、流入端部や流出端部の限られた面積の中で、効率良く流入凹部や流出凹部を配置するためには、「一方の凹部」と「他方の凹部」との距離（パス長）を活性炭成型体の強度と浄水性能が保てる範囲でできるだけ短く均一にする方が好ましい。このようにすれば、効率良く水を浄化することができ、活性炭成型体の長寿命化に繋がる。従って、「他方の凹部」を囲む「一方の凹部」は、「他方の凹部」の外周近くにおいて該外周に沿った形状が好ましい。環状溝といった「一方の凹部」が「他方の凹部」を囲む閉じた溝である場合、流入凹部１１１１のような断面円形の穴を複数配置する場合よりも、パス長の均一化を図り易い。
平面視においてＣ字形の溝といった閉じていない「一方の凹部」が「他方の凹部」を囲んでいる場合も、「他方の凹部」の外周近くに配置されると、効率良く水を浄化することができ、活性炭成型体の長寿命化に繋がる。 In the case of the activated carbon molded body 100 shown in FIG. 5, the maximum recess having the largest area Sin is the outflow recess 1212. Since the area Sin of the inner surface of the maximum recess is as large as 0.5 times or more the area Sout of the outer surface 130 of the activated carbon molded body 100, the pressure loss of water W can be further reduced and the filtration flow rate is further increased. can do. Therefore, when the activated carbon is in the form of particles, the particles of the activated carbon can be made smaller, and the amount of activated carbon in a unit volume can be increased to improve the adsorption performance of the activated carbon.
When the area Sin of the inner side surface 114 of the inflow recess 111 is as large as Sin / Sout ≧ 0.5, the pressure loss of water W is low, the inner side surface 114 is less likely to be clogged, and the life of the activated carbon molded body 100 is extended. become longer.
As described above, in order for the annular "one recess" to surround the annular "other recess", it is necessary for the "one recess" to have a larger circumference than the "other recess" in a plan view. is there. This increases the area Sin of the inner surface of the "one recess". When a plurality of holes having a circular cross section such as the inflow recess 1111 are arranged to surround the "other recess", it is necessary to secure a wall thickness (corresponding to Ta in FIG. 6) in order to secure the strength of the activated carbon molded body. , There is a limit to the number of holes, and even if the areas of the inner surfaces of these holes are combined, the area of the inner surface of the annular groove is much smaller. When the "one recess" such as an annular groove is a closed groove surrounding the "other recess", the inner inner surface and the outer inner surface are continuous, which is suitable for increasing the area of the inner surface. Is.
Further, in order to efficiently arrange the inflow recess and the outflow recess in the limited area of the inflow end and the outflow end, the distance (path length) between the "one recess" and the "other recess". It is preferable to make it as short and uniform as possible within the range where the strength and water purification performance of the activated carbon molded body can be maintained. By doing so, water can be purified efficiently, which leads to a long life of the activated carbon molded body. Therefore, the "one recess" surrounding the "other recess" preferably has a shape along the outer circumference of the "other recess" near the outer circumference. When the "one recess" such as the annular groove is a closed groove surrounding the "other recess", it is easier to make the path length uniform than when a plurality of holes having a circular cross section such as the inflow recess 1111 are arranged.
Even if an unclosed "one recess" such as a C-shaped groove surrounds the "other recess" in a plan view, if it is placed near the outer circumference of the "other recess", water can be purified efficiently. This leads to a longer life of the activated carbon molded body.

さらに、流入凹部１１１が複数ある場合、その分、通水面積が増えるため、水Ｗの圧力損失がさらに低くなり、活性炭成型体１００の濾過流量がさらに多くなる。流出凹部１２１が複数ある場合も、その分、通水面積が増えるため、水Ｗの圧力損失がさらに低くなり、活性炭成型体１００の濾過流量がさらに多くなる。 Further, when there are a plurality of inflow recesses 111, the water flow area is increased by that amount, so that the pressure loss of the water W is further reduced and the filtration flow rate of the activated carbon molded body 100 is further increased. Even when there are a plurality of outflow recesses 121, the water flow area is increased by that amount, so that the pressure loss of the water W is further reduced, and the filtration flow rate of the activated carbon molded body 100 is further increased.

図５に示す凹部１１１，１２１は、中心軸ＡＸ１に沿った方向（Ｄ１，Ｄ２）における位置に関わらず同じ断面形状を有している。むろん、脱型を考慮して凹部１１１，１２１をテーパー状にしてもよい。 The recesses 111 and 121 shown in FIG. 5 have the same cross-sectional shape regardless of their positions in the directions (D1, D2) along the central axis AX1. Of course, the recesses 111 and 121 may be tapered in consideration of demolding.

図６において模式的に示す活性炭成型体１００は、活性炭ＡＣ１同士がバインダーＢ１で接着され、活性炭ＡＣ１の粒子間に隙間１０５がある。この隙間１０５を水Ｗが内方向Ｄ３や外方向Ｄ４へ流通する。むろん、活性炭成型体１００の形状が保持される限り、バインダーを省略しても良い。活性炭成型体１００は、水Ｗが活性炭ＡＣ１の粒子間の隙間１０５を通過するときに活性炭ＡＣ１の浄化機能が発揮される。 In the activated carbon molded body 100 schematically shown in FIG. 6, the activated carbon AC1s are bonded to each other by the binder B1, and there is a gap 105 between the particles of the activated carbon AC1. Water W flows through the gap 105 in the inward direction D3 and the outward direction D4.

凹部１１１，１２１に折れ曲がり部位１１６，１２６があることにより、凹部１１１，１２１の内側面１１４，１２４が拡張され、水Ｗの圧力損失がさらに低くなり、濾過流量をさらに多くなる。 As shown in FIG. 9, the inflow recess 111 branches into three on the way from the opening end 112 to the first closed end 113, and two of the inflow recesses 111 are bent portions extending outward D4 from the branch point. Has 116. The outflow recesses 121 are arranged at two locations between the inflow recesses 111 and at two locations between the outer surface 130 and the inflow recess 111. The outflow recess 121 between the outer side surface 130 and the inflow recess 111 has a shape that is recessed from the opening end 122 toward the inflow end 110 (direction D2) and then bends inward D3 to reach the second closed end 123. are doing. The bent portion 126 extends inward D3 from the bent point, in other words, extends outward D4 from the second closed end 123.
Since the recesses 111 and 121 have the bent portions 116 and 126, the inner side surfaces 114 and 124 of the recesses 111 and 121 are expanded, the pressure loss of the water W is further reduced, and the filtration flow rate is further increased.

（３）活性炭成型体を含む濾過カートリッジの製造方法の具体例：
次に、図８，９に示す活性炭成型体１００Ｂを例にとって、活性炭成型体の製造方法の例を説明する。
図１０に示す製法は、バインダーＢ１を用いて活性炭成型体１００Ｂの１／２分割体１０１を製造する例を示している。 (3) Specific example of a method for manufacturing a filtration cartridge containing an activated carbon molded body:
Next, an example of a method for producing the activated carbon molded body will be described by taking the activated carbon molded body 100B shown in FIGS. 8 and 9 as an example.
The manufacturing method shown in FIG. 10 shows an example of manufacturing a 1/2 divided body 101 of the activated carbon molded body 100B using the binder B1.

混合工程Ｓ１では、活性炭ＡＣ１とバインダーＢ１と必要に応じて添加剤ＡＤ１とを含む材料を混合する。この混合には、粉体混合、液状分散媒に固体分散質を分散させる混練、等が含まれる。添加剤ＡＤ１には、水といった分散媒が含まれる。混合には、ミキサー、ブレンダー、水平円筒型、Ｖ型、二重円錐型、正方立体型、Ｓ型、連続Ｖ型、ボールミル型、ロッキング型、クロスロータリー型、リボン型、スクリュー型、ロター型、パグミル型、遊星型、タービン型、高速流動型、回転円板型、等の混合装置を使用しても良い。混合装置の回転速度は、混合物の温度の偏りを少なくする速度であればよく、例えば、１５〜２００ｒｐｍとすることができる。 In the mixing step S1, a material containing activated carbon AC1, binder B1, and additive AD1 if necessary is mixed. This mixing includes powder mixing, kneading in which a solid dispersant is dispersed in a liquid dispersion medium, and the like. Additive AD1 contains a dispersion medium such as water. For mixing, mixer, blender, horizontal cylindrical type, V type, double cone type, square three-dimensional type, S type, continuous V type, ball mill type, locking type, cross rotary type, ribbon type, screw type, rotor type, A mixing device such as a pug mill type, a planetary type, a turbine type, a high-speed flow type, a rotary disk type, or the like may be used. The rotation speed of the mixing device may be any speed as long as it reduces the bias in the temperature of the mixture, and can be, for example, 15 to 200 rpm.

充填工程Ｓ２では、混合工程Ｓ１で得られる混合物Ｍ１を例えば図１１に示すような成型装置２００の成形型のキャビティ２３０内に充填する。 In the filling step S2, the mixture M1 obtained in the mixing step S1 is filled into the cavity 230 of the molding die of the molding apparatus 200 as shown in FIG. 11, for example.

図１１に示す成型装置２００は、金型２１０，２２０、金型２１０に挿入された入子型２１２、ヒーター（不図示）、油圧プレス機（不図示）、等を備えている。入子型２１２は、母型である金型２１０に対して嵌め込まれる固定式の部分的金型である。金型２１０，２２０と入子型２１２とで形成されるキャビティ２３０は、活性炭成型体１００Ｂの１／２分割体１０１の形状に合わせられている。尚、図１１に示すキャビティ２３０は、分割体１０１同士を合わせる面が下となる形状である。充填工程Ｓ２では、入子型２１２が嵌め込まれた金型２１０の中に混合物Ｍ１を充填し、金型２１０，２２０を閉じる。 The molding apparatus 200 shown in FIG. 11 includes dies 210 and 220, a nesting die 212 inserted into the die 210, a heater (not shown), a hydraulic press (not shown), and the like. The nesting mold 212 is a fixed partial mold that is fitted into a mold 210 that is a master mold. The cavity 230 formed by the molds 210 and 220 and the nesting mold 212 is matched to the shape of the 1/2 divided body 101 of the activated carbon molded body 100B. The cavity 230 shown in FIG. 11 has a shape in which the surface on which the divided bodies 101 are aligned is on the bottom. In the filling step S2, the mixture M1 is filled in the mold 210 into which the nesting mold 212 is fitted, and the molds 210 and 220 are closed.

成型工程Ｓ３では、キャビティ２３０内の混合物Ｍ１のバインダーＢ１が軟化温度以上となるようにヒーターで金型２１０，２２０を加熱し、油圧プレス機で混合物Ｍ１に圧縮力を加える圧縮成形を行う。圧縮成形とは、閉じたキャビティの中の材料に圧力を加える成形をいう。バインダーの軟化温度が範囲Ｔsl〜Ｔsh（℃）で示される場合、加熱温度の下限をＴshとすればよい。軟化温度は、JIS K7206：1999（プラスチック―熱可塑性プラスチック―ビカット軟化温度（ＶＳＴ）試験方法）に規定されるビカット軟化温度とする。バインダーの軟化温度が不明である場合、軟化温度よりも高い融点を加熱温度の下限とすればよい。また、バインダーの発火点が最低温度Ｔilで示される場合、加熱温度の上限をＴil未満とすればよい。なお、ポリエチレン等の熱可塑性樹脂の発火点は、通常、３５０℃以上であるため、加熱混合温度の好ましい上限は３５０℃未満である。バインダーの融点が範囲Ｔml〜Ｔmhで示される場合、加熱温度のより好ましい上限はＴml＋７０℃とすればよく、加熱温度の好ましい下限はＴmhとすればよい。
尚、活性炭を含む材料の圧縮成形は、特開2015-47523号公報に開示された技術等を準用することができる。 In the molding step S3, the dies 210 and 220 are heated by a heater so that the binder B1 of the mixture M1 in the cavity 230 becomes equal to or higher than the softening temperature, and compression molding is performed by applying a compressive force to the mixture M1 by a hydraulic press. Compression molding refers to molding that applies pressure to the material in a closed cavity. When the softening temperature of the binder is indicated by the range T sl to T sh (° C.), the lower limit of the heating temperature may be T sh . The softening temperature shall be the Vicat softening temperature specified in JIS K7206: 1999 (Plastic-thermoplastic plastic-Vicat softening temperature (VST) test method). When the softening temperature of the binder is unknown, the melting point higher than the softening temperature may be set as the lower limit of the heating temperature. Further, when the ignition point of the binder is indicated by the minimum temperature Til , the upper limit of the heating temperature may be set to less than Til . Since the ignition point of a thermoplastic resin such as polyethylene is usually 350 ° C. or higher, the preferable upper limit of the heating and mixing temperature is less than 350 ° C. When the melting point of the binder is indicated in the range T ml to T mh , the more preferable upper limit of the heating temperature may be T ml + 70 ° C., and the preferable lower limit of the heating temperature may be T mh .
For compression molding of materials containing activated carbon, the techniques disclosed in JP-A-2015-47523 can be applied mutatis mutandis.

冷却工程Ｓ４では、金型２１０，２２０の加熱を停止し、成型物の温度がバインダーＢ１の軟化温度未満となるように成型物を冷却する。この冷却には、水冷といった液体の冷却媒体による強制冷却、送風冷却といった気体の冷却媒体による強制冷却、等を用いることができる。
脱型工程Ｓ５では、油圧プレス機のプレス圧から金型２１０，２２０を解放して開き、キャビティ２３０から成型物である１／２分割体１０１を取り出す。
尚、成型工程Ｓ３の直後に脱型工程を行って分割体１０１を取り出し、冷却工程を行って分割体１０１を冷却してもよい。 In the cooling step S4, the heating of the molds 210 and 220 is stopped, and the molded product is cooled so that the temperature of the molded product is lower than the softening temperature of the binder B1. For this cooling, forced cooling using a liquid cooling medium such as water cooling, forced cooling using a gas cooling medium such as blast cooling, or the like can be used.
In the demolding step S5, the dies 210 and 220 are released from the press pressure of the hydraulic press and opened, and the 1/2 divided body 101 which is a molded product is taken out from the cavity 230.
Immediately after the molding step S3, a demolding step may be performed to take out the divided body 101, and a cooling step may be performed to cool the divided body 101.

最後に、１／２分割体１０１同士を合わせるための金型に分割体１０１同士を合わせた状態で入れて再加熱して接合したり、分割体１０１同士を接着剤等といった接合手段で接合したりすると、活性炭成型体１００Ｂが得られる。上述したように、分割体１０１同士を合わせる面は、図１１に示すキャビティ２３０において下を向いている面である。
尚、接合する分割体１０１は、同体（同じ形状の分割体）に限らず、左右対称の分割体同士、左右非対称の分割体同士でもよい。むろん、接合する分割体は、３個以上でもよい。 Finally, the divided bodies 101 are put together in a mold for joining the 1/2 divided bodies 101 and reheated for joining, or the divided bodies 101 are joined by a joining means such as an adhesive. Then, the activated carbon molded body 100B is obtained. As described above, the surface where the divided bodies 101 are aligned with each other is the surface facing downward in the cavity 230 shown in FIG.
The divided body 101 to be joined is not limited to the same body (divided body having the same shape), but may be symmetrical divided bodies or asymmetrical divided bodies. Of course, the number of divided bodies to be joined may be three or more.

以上の工程Ｓ１〜Ｓ５により、活性炭成型体を製造することができる。
尚、キャビティの形状を活性炭成型体１００の全体形状に合わせることができれば、脱型工程により活性炭成型体１００を取り出すことができる。
また、成型装置の成形型は、図１１に示す入子型２１２を除いた２個に限定されず、３個以上（入子型を除く。）でもよい。 The activated carbon molded body can be produced by the above steps S1 to S5.
If the shape of the cavity can be matched to the overall shape of the activated carbon molded body 100, the activated carbon molded body 100 can be taken out by the demolding step.
Further, the molding die of the molding apparatus is not limited to two except for the nesting die 212 shown in FIG. 11, and may be three or more (excluding the nesting die).

尚、活性炭ＡＣ１の代わりに賦活前の活性炭原料を用い、得られる成型物を賦活して活性炭成型体１００を形成してもよい。賦活とは、炭素質材料の微細孔を発達させ多孔質に変える反応である。賦活には、水蒸気、二酸化炭素、空気、等の存在下で高温処理するガス賦活、塩化亜鉛、硫酸塩、リン酸、等で薬品処理する薬品賦活、薬品と水蒸気を併用する賦活、等がある。賦活には、炭化処理後に賦活処理することが含まれる。炭化処理は、例えば、窒素、アルゴン、等の不活性雰囲気下、６００〜８００℃で成型物を炭化する処理とすることができる。炭化処理後の賦活処理は、例えば、水蒸気、二酸化炭素、等の酸化性ガスの雰囲気下、７００〜１１００℃で炭化物を活性化する処理とすることができる。 Instead of the activated carbon AC1, an activated carbon raw material before activation may be used, and the obtained molded product may be activated to form the activated carbon molded body 100. Activation is a reaction that develops micropores in a carbonaceous material to make it porous. Activation includes gas activation that is treated at high temperature in the presence of water vapor, carbon dioxide, air, etc., chemical activation that is treated with chemicals such as zinc chloride, sulfate, and phosphoric acid, and activation that uses both chemicals and water vapor. .. Activation includes activation treatment after carbonization treatment. The carbonization treatment can be a treatment of carbonizing the molded product at 600 to 800 ° C. under an inert atmosphere such as nitrogen or argon. The activation treatment after the carbonization treatment can be, for example, a treatment for activating the carbide at 700 to 1100 ° C. in an atmosphere of an oxidizing gas such as water vapor or carbon dioxide.

得られた活性炭成型体１００は、浄水カートリッジ２０の吸着剤部３０に使用することができる。外方向Ｄ４において活性炭成型体１００の外側に筒状の不織布３１を配置する場合には、例えば、筒状の不織布３１に活性炭成型体１００を挿入することにより吸着剤部３０を形成することができる。中空糸膜束ＢＨ１が収容された中空糸膜ケース７０の外嵌部８０に吸着剤部３０の端部３０ｂを入れて接着剤で固定すると、吸着剤部３０が中空糸膜ケース７０に保持され、浄水カートリッジ２０が形成される。 The obtained activated carbon molded body 100 can be used for the adsorbent portion 30 of the water purification cartridge 20. When the tubular non-woven fabric 31 is arranged outside the activated carbon molded body 100 in the outward direction D4, for example, the adsorbent portion 30 can be formed by inserting the activated carbon molded body 100 into the tubular non-woven fabric 31. .. When the end portion 30b of the adsorbent portion 30 is inserted into the outer fitting portion 80 of the hollow fiber membrane case 70 containing the hollow fiber membrane bundle BH1 and fixed with an adhesive, the adsorbent portion 30 is held by the hollow fiber membrane case 70. , The water purification cartridge 20 is formed.

吐水ヘッド１０から使用済みの浄水カートリッジ２０を取り外す場合、まず、ねじ１１ａ，１８ａの螺合を解除する向きに把持部１８を回し、吐水部１１から把持部１８を取り外す。このとき、図２（ｂ）に示すように、吐水部１１から浄水カートリッジ２０における吸着剤部３０及び外嵌部８０が出た状態となる。次に、外嵌部８０を掴み、吐水部１１から浄水カートリッジ２０を流下方向Ｄ１とは反対の方向（延出方向Ｄ２）へ引き出せばよい。吐水ヘッド１０に新しい浄水カートリッジ２０を取り付ける場合、外嵌部８０を掴み、吐水部１１に流出口７５から浄水カートリッジ２０を流下方向Ｄ１へ押し込めばよい。図２（ａ）に示すように流出口７５が吐水部１１の接続口１２に挿入されると、浄水カートリッジ２０が吐水部１１に取り付けられる。 When removing the used water purification cartridge 20 from the water discharge head 10, first, the grip portion 18 is turned in the direction of unscrewing the screws 11a and 18a, and the grip portion 18 is removed from the water discharge portion 11. At this time, as shown in FIG. 2B, the adsorbent portion 30 and the outer fitting portion 80 of the water purification cartridge 20 are exposed from the water discharge portion 11. Next, the outer fitting portion 80 may be grasped, and the water purification cartridge 20 may be pulled out from the water discharge portion 11 in the direction opposite to the flow direction D1 (extension direction D2). When a new water purification cartridge 20 is attached to the water discharge head 10, the outer fitting portion 80 may be grasped and the water purification cartridge 20 may be pushed into the water discharge portion 11 from the outlet 75 in the flow direction D1. When the outlet 75 is inserted into the connection port 12 of the water discharge unit 11 as shown in FIG. 2A, the water purification cartridge 20 is attached to the water discharge unit 11.

さらに、図２，３を参照して、浄水カートリッジ２０が取り付けられた吐水ヘッド１０の水の流れを説明する。
切替レバー１５が水道水側にある時、浄水カートリッジ２０からの浄水は流出しない。ホース１９からの水道水は、吐水ヘッド１０の中で浄水カートリッジ２０の外側を流下方向Ｄ１へ流れ、吐水部１１の水出口１３から吐出される。 Further, with reference to FIGS. 2 and 3, the flow of water in the water discharge head 10 to which the water purification cartridge 20 is attached will be described.
When the switching lever 15 is on the tap water side, the purified water from the water purification cartridge 20 does not flow out. The tap water from the hose 19 flows in the water discharge head 10 on the outside of the water purification cartridge 20 in the flow direction D1, and is discharged from the water outlet 13 of the water discharge unit 11.

切替レバー１５が浄水側にある時、吐水ヘッド１０の中で浄水カートリッジ２０の外側にある水道水は流出しない。図１に示すホース１９からの水道水（原水）は、図３に示す矢印のように、活性炭成型体１００の流入端部１１０、及び、外側面１３０の外側の不織布３１から吸着剤部３０に入る。図５，６に示すように、流入端部１１０に配置されている開口端１１２から流入凹部１１１に流入した原水（Ｗ）は、流入凹部１１１の内側面１１４から活性炭成型体１００内に入り、少なくとも一部が横断面ＣＳ１に沿った方向（Ｄ３，Ｄ４）にある流出凹部１２１へ移動する。また、不織布３１を通過した水Ｗは、外側面１３０から活性炭成型体１００内に入り、少なくとも一部が内方向Ｄ３にある流出凹部１２１へ移動する。活性炭成型体１００内において、水Ｗ１は隙間１０５を通る間に活性炭ＡＣ１の機能により吸着対象の物質（例えば遊離残留塩素や有機物等の微量成分）が除去される。浄化されて内側面１２４から流出凹部１２１内に入った水Ｗは、流出端部１２０に配置されている開口端１２２から外部へ流出し、連絡口７４から中空糸膜束収容部７１の内部空間７０ｃに入る。内部空間７０ｃの水は、中空糸膜束ＢＨ１において閉塞端部ＢＨ１ａから開口端部ＢＨ１ｂへ移動し、１μｍ程度以上の細かい濁りや鉄サビや一般細菌が取り除かれる。開口端部ＢＨ１ｂからの浄水は、流出口７５から流出し、吐水部１１の水出口１３から吐出される。 When the switching lever 15 is on the water purification side, the tap water outside the water purification cartridge 20 does not flow out in the water discharge head 10. The tap water (raw water) from the hose 19 shown in FIG. 1 is transferred from the inflow end 110 of the activated carbon molded body 100 and the non-woven fabric 31 outside the outer surface 130 to the adsorbent portion 30 as shown by the arrows in FIG. enter. As shown in FIGS. 5 and 6, the raw water (W) that has flowed into the inflow recess 111 from the opening end 112 arranged at the inflow end 110 enters the activated carbon molded body 100 from the inner surface 114 of the inflow recess 111. At least a part moves to the outflow recess 121 in the direction (D3, D4) along the cross section CS1. Further, the water W that has passed through the non-woven fabric 31 enters the activated carbon molded body 100 from the outer surface 130, and at least a part of the water W moves to the outflow recess 121 in the inward direction D3. In the activated carbon molded body 100, substances to be adsorbed (for example, trace components such as free residual chlorine and organic substances) are removed by the function of the activated carbon AC1 while the water W1 passes through the gap 105. The water W that has been purified and entered the outflow recess 121 from the inner side surface 124 flows out from the opening end 122 arranged at the outflow end portion 120, and flows out from the communication port 74 to the internal space of the hollow fiber membrane bundle accommodating portion 71. Enter 70c. The water in the internal space 70c moves from the closed end BH1a to the open end BH1b in the hollow fiber membrane bundle BH1, and fine turbidity of about 1 μm or more, iron rust, and general bacteria are removed. The purified water from the opening end portion BH1b flows out from the outflow port 75 and is discharged from the water outlet 13 of the water discharge portion 11.

吸着剤部３０に不織布３１が無い場合、ホース１９からの水道水が直接、外側面１３０から活性炭成型体１００内に入り、少なくとも一部が流出凹部１２１へ移動する。その間に活性炭ＡＣ１の機能により吸着対象の物質が除去される。 When the non-woven fabric 31 is not present in the adsorbent portion 30, tap water from the hose 19 directly enters the activated carbon molded body 100 from the outer surface 130, and at least a part of the tap water moves to the outflow recess 121. During that time, the substance to be adsorbed is removed by the function of the activated carbon AC1.

図７に示す活性炭成型体１００Ａを用いる場合、流入端部１１０に配置されている渦巻き状の開口端１１２から流入凹部１１１に流入した原水（Ｗ）が内側面１１４から活性炭成型体１００内に入り、少なくとも一部が流出凹部１２１へ移動する。また、外側面１３０から活性炭成型体１００内に入った水Ｗの少なくとも一部が内方向Ｄ３にある流出凹部１２１へ移動する。水Ｗが隙間１０５を通る間に活性炭ＡＣ１の機能により吸着対象の物質が除去される。浄化されて内側面１２４から流出凹部１２１内に入った水Ｗは、流出端部１２０に配置されている渦巻き状の開口端１２２から外部へ流出し、中空糸膜束ＢＨ１を通過して浄水として流出口７５から流出し、水出口１３から吐出される。 When the activated carbon molded body 100A shown in FIG. 7 is used, the raw water (W) that has flowed into the inflow recess 111 from the spiral opening end 112 arranged at the inflow end 110 enters the activated carbon molded body 100 from the inner side surface 114. , At least a part moves to the outflow recess 121. Further, at least a part of the water W that has entered the activated carbon molded body 100 from the outer surface 130 moves to the outflow recess 121 in the inward direction D3. While the water W passes through the gap 105, the substance to be adsorbed is removed by the function of the activated carbon AC1. The water W that has been purified and entered the outflow recess 121 from the inner side surface 124 flows out from the spiral opening end 122 arranged at the outflow end portion 120, passes through the hollow fiber membrane bundle BH1, and is used as purified water. It flows out from the outlet 75 and is discharged from the water outlet 13.

図８，９に示す活性炭成型体１００Ｂを用いる場合、流入端部１１０に配置されている直線状の開口端１１２から原水（Ｗ）が流入凹部１１１に流入する。この水Ｗは、３つに分岐した流入凹部１１１の内側面１１４から活性炭成型体１００内に入り、少なくとも一部が横断面ＣＳ１に沿った方向（Ｄ３，Ｄ４）にある流出凹部１２１へ移動する。また、一部の水Ｗは、流入凹部１１１の折れ曲がり部位１１６から流出凹部１２１の折れ曲がり部位１２６へ移動する。さらに、流入端部１１０から直接、活性炭成型体１００Ｂ内に原水（Ｗ）が入り、少なくとも一部が流下方向Ｄ１にある折れ曲がり部位１２６（流出凹部１２１）へ移動する。外側面１３０から活性炭成型体１００内に入った水Ｗの少なくとも一部は、内方向Ｄ３にある流出凹部１２１へ移動する。水Ｗが隙間１０５を通る間に活性炭ＡＣ１の機能により吸着対象の物質が除去される。浄化されて内側面１２４から流出凹部１２１内に入った水Ｗは、流出端部１２０に配置されている直線状の開口端１２２から外部へ流出し、中空糸膜束ＢＨ１を通過して浄水として流出口７５から流出し、水出口１３から吐出される。 When the activated carbon molded body 100B shown in FIGS. 8 and 9 is used, raw water (W) flows into the inflow recess 111 from the linear opening end 112 arranged at the inflow end 110. This water W enters the activated carbon molded body 100 from the inner side surface 114 of the inflow recess 111 branched into three, and moves to the outflow recess 121 in which at least a part thereof is in the direction (D3, D4) along the cross section CS1. .. Further, some water W moves from the bent portion 116 of the inflow recess 111 to the bent portion 126 of the outflow recess 121. Further, the raw water (W) enters the activated carbon molded body 100B directly from the inflow end 110, and at least a part of the raw water (W) moves to the bent portion 126 (outflow recess 121) in the flow direction D1. At least a part of the water W that has entered the activated carbon molded body 100 from the outer side surface 130 moves to the outflow recess 121 in the inward direction D3. While the water W passes through the gap 105, the substance to be adsorbed is removed by the function of the activated carbon AC1. The water W that has been purified and entered the outflow recess 121 from the inner side surface 124 flows out from the linear opening end 122 arranged at the outflow end portion 120, passes through the hollow fiber membrane bundle BH1, and is used as purified water. It flows out from the outlet 75 and is discharged from the water outlet 13.

活性炭成型体１００は、閉塞端１１３，１２３の間の横断面ＣＳ１において流入凹部１１１と流出凹部１２１の両方が存在することにより、水Ｗの圧力損失が低く、濾過流量が多い。このため、活性炭の粒子を小さくすることができ、単位体積における活性炭量を増やして活性炭の吸着性能を向上させることができる。また、流入凹部１１１の内側面１１４の面積Ｓinが大きいので、目詰まりし難く、活性炭成型体１００の寿命が長くなる。活性炭成型体１００の寿命が長くなれば、その分、活性炭成型体１００を小さくすることができる。従って、本具体例は、活性炭成型体を使用した浄水カートリッジ及び浄水器を小型化することが可能な技術を提供することができる。 In the activated carbon molded body 100, the pressure loss of water W is low and the filtration flow rate is large because both the inflow recess 111 and the outflow recess 121 are present in the cross section CS1 between the closed ends 113 and 123. Therefore, the particles of activated carbon can be made smaller, and the amount of activated carbon in a unit volume can be increased to improve the adsorption performance of activated carbon. Further, since the area Sin of the inner side surface 114 of the inflow recess 111 is large, clogging is unlikely to occur, and the life of the activated carbon molded body 100 is extended. The longer the life of the activated carbon molded body 100 is, the smaller the activated carbon molded body 100 can be. Therefore, this specific example can provide a technique capable of miniaturizing a water purification cartridge and a water purifier using an activated carbon molded body.

例えば、図５に示す活性炭成型体１００を浄水カートリッジ２０において逆の向きに配置すると、凹部１２１が流入凹部として機能し、凹部１１１が流出凹部として機能する。この場合、「最大凹部」は、流入凹部としての凹部１２１２となる。ここで、浄化された水Ｗが外側面１３０から活性炭成型体１００外に出るように吐水ヘッド１０を設計すれば、流入凹部としての最大凹部１２１２から外側面１３０へ水Ｗが移動するので、効率良く水Ｗを浄化することができる。
図７に示す活性炭成型体１００Ａは、浄水カートリッジ２０において逆の向きに配置しても渦巻きの向きが逆になるだけであり、類似する作用及び効果により水Ｗを浄化することができる。
図８，９に示す活性炭成型体１００Ｂも、浄水カートリッジ２０において逆の向きに配置することが可能である。この場合、浄化された水Ｗが外側面１３０から活性炭成型体１００外に出るように吐水ヘッド１０を設計すればよい。 The orientation of the activated carbon molded body in the water purifier is not limited to the orientation shown in FIG. 3, and may be the opposite orientation such that the portion 120 is the inflow end and the portion 110 is the outflow end.
For example, when the activated carbon molded body 100 shown in FIG. 5 is arranged in the opposite direction in the water purification cartridge 20, the recess 121 functions as an inflow recess and the recess 111 functions as an outflow recess. In this case, the "maximum recess" is the recess 1212 as the inflow recess. Here, if the water discharge head 10 is designed so that the purified water W goes out of the activated carbon molded body 100 from the outer surface 130, the water W moves from the maximum recess 1212 as the inflow recess to the outer surface 130, which is efficient. Water W can be purified well.
Even if the activated carbon molded body 100A shown in FIG. 7 is arranged in the opposite direction in the water purification cartridge 20, the direction of the spiral is only reversed, and the water W can be purified by a similar action and effect.
The activated carbon molded body 100B shown in FIGS. 8 and 9 can also be arranged in the opposite direction in the water purification cartridge 20. In this case, the water discharge head 10 may be designed so that the purified water W goes out of the activated carbon molded body 100 from the outer surface 130.

溝形状の流入凹部や流出凹部は、平面視において、環状や渦巻き状の溝に限定されず、四角形といった多角形の溝、波形状の溝、折れ線状の溝、星形の溝、Ｄ字形の溝、Ｃ字形の溝（例えば２７０〜３５９°繋がっていて１〜９０°切れている溝）、環状溝を複数に分割した溝、等でもよい。これらの溝は、いずれも、「他方の凹部」を囲む「一方の凹部」となり得る。すなわち、「一方の凹部」は、平面視において閉じている溝のみならず、平面視において閉じていない溝、例えば、渦巻き状の溝、Ｃ字形の溝、環状溝を複数に分割した溝、等でもよい。従って、流入凹部及び流出凹部と交差する横断面において、渦巻き状の溝の「他方の凹部」を環状溝の「一方の凹部」が囲んだ活性炭成型体、環状溝の「他方の凹部」を渦巻き状の溝の「一方の凹部」が囲んだ活性炭成型体、等も、本技術に含まれる。
尚、流入凹部及び流出凹部と交差する横断面において「他方の凹部」を囲む溝の「一方の凹部」が無い場合や、Ｓin／Ｓout≧０．５の内側面の凹部が無い場合も、流入凹部の第一閉塞端が流出凹部の第二閉塞端よりも流出端部側にあれば、本技術の基本的な作用及び効果が得られる。 Groove-shaped inflow recesses and outflow recesses are not limited to annular or spiral grooves in a plan view, but are polygonal grooves such as quadrangles, wavy grooves, polygonal grooves, star-shaped grooves, and D-shaped grooves. A groove, a C-shaped groove (for example, a groove connected by 270 to 359 ° and cut by 1 to 90 °), a groove obtained by dividing an annular groove into a plurality of grooves, and the like may be used. Each of these grooves can be a "one recess" that surrounds the "other recess." That is, the "one concave portion" is not only a groove that is closed in a plan view, but also a groove that is not closed in a plan view, for example, a spiral groove, a C-shaped groove, a groove obtained by dividing an annular groove into a plurality of grooves, and the like. It may be. Therefore, in the cross section intersecting the inflow recess and the outflow recess, the activated carbon molded body in which the "other recess" of the spiral groove is surrounded by the "one recess" of the annular groove, and the "other recess" of the annular groove are swirled. The present technology also includes an activated carbon molded body surrounded by "one concave portion" of a shaped groove.
It should be noted that the inflow also occurs when there is no "one recess" of the groove surrounding the "other recess" in the cross section intersecting the inflow recess and the outflow recess, or when there is no recess on the inner surface of Sin / Sout ≥ 0.5. If the first closed end of the recess is closer to the outflow end than the second closed end of the outflow recess, the basic actions and effects of the present technology can be obtained.
