The water passage is formed between the molded activated carbon and the inner wall of the case main body (for example, the inner wall 41 in the embodiment), and one end of the molded activated carbon is disposed opposite to the lid. The elastic body is sandwiched between the lid body and the molded activated carbon.
請求項３に記載した浄水カートリッジは、請求項１または２に記載の浄水カートリッジにおいて、前記成型活性炭の下流側には、筒状体（例えば、実施の形態におけるケース４４）内に収容された中空糸膜（例えば、実施の形態における中空糸膜５２）が設けられていることを特徴とする。 A water purification cartridge according to claim 3 is the water purification cartridge according to claim 1 or 2, wherein a hollow accommodated in a cylindrical body (for example, a case 44 in the embodiment) is provided downstream of the molded activated carbon. A yarn membrane (for example, the hollow fiber membrane 52 in the embodiment) is provided.
請求項４に記載した浄水カートリッジは、請求項３に記載の浄水カートリッジにおいて、前記筒状体が、その一端に支持部（例えば、実施の形態における支持部８１）を備え、該支持部と前記成型活性炭とによって前記弾性体が挟持されていることを特徴とする。 The water purification cartridge according to claim 4 is the water purification cartridge according to claim 3, wherein the cylindrical body includes a support portion (for example, the support portion 81 in the embodiment) at one end thereof, and the support portion and the The elastic body is sandwiched by molded activated carbon .
請求項５に記載した浄水カートリッジは、請求項１〜４のいずれか一項に記載の浄水カートリッジにおいて、前記活性炭が平均粒子径５０〜１５０μｍの粉末状活性炭であり、前記成型活性炭中のバインダーの含有量が前記粉末状活性炭に対して０．１〜２質量％であることを特徴とする。 The water purification cartridge according to claim 5 is the water purification cartridge according to any one of claims 1 to 4, wherein the activated carbon is powdered activated carbon having an average particle diameter of 50 to 150 μm, and the binder in the molded activated carbon Content is 0.1-2 mass% with respect to the said powdery activated carbon, It is characterized by the above-mentioned.
請求項１に記載した発明によれば、活性炭とバインダーとからなる成型活性炭の水通路に面した側面をシート状物で覆うことで、成型活性炭の形状が崩れるのを防止することができるため、バインダーの含有量を低下させることができる。したがって、成型活性炭の吸着性能を確保しつつ組み立て時の取り扱い容易性を確保することができる。
また、通水時に成型活性炭の原水通路方向への膨潤などによる変形をシート状物によって防止するとともに、シート状物が設けられていない方向への成型活性炭の膨潤等による変形を許容しつつ、この変形分を弾性体によって吸収することができるため、成型活性炭の変形によりシート状物に過度の負担がかかるのを防止するとともに、ケースの負担を軽減することができる効果がある。
According to the invention described in claim 1, by covering the side face facing the water passage of the molded activated carbon composed of activated carbon and a binder with a sheet-like material, the shape of the molded activated carbon can be prevented from collapsing, The binder content can be reduced. Therefore, the ease of handling at the time of assembly can be ensured while ensuring the adsorption performance of the molded activated carbon .
Moreover, while preventing deformation due to swelling of the molded activated carbon in the direction of the raw water passage during water flow, etc., while allowing deformation due to swelling of the molded activated carbon in the direction where the sheet is not provided, this Since the deformation can be absorbed by the elastic body, it is possible to prevent an excessive burden on the sheet-like material due to the deformation of the molded activated carbon, and to reduce the burden on the case.
請求項２に記載した発明によれば、請求項１の効果に加え、活性炭と蓋体とによって弾性体を挟持することで、成型活性炭の膨潤等による変形を許容しつつ、この変形分を弾性体によって吸収することができるため、蓋体の負担を軽減することができる。 According to the second aspect of the present invention, in addition to the effect of the first aspect, by holding the elastic body between the activated carbon and the lid, the deformation due to the swelling of the molded activated carbon is allowed, and the deformation is elastic. Since it can be absorbed by the body, the burden on the lid can be reduced.
請求項４に記載した発明によれば、請求項３の効果に加え、活性炭の開口端に弾性体が接することになるため、成型活性炭の膨潤等による変形を許容しつつ、ケースや蓋体の負担を軽減することができる。 According to the invention described in claim 4, in addition to the effect of claim 3, since that would elastic member to the open end of the activated carbon in contact, while allowing the deformation due to swelling or the like of the molded activated carbon, case or the lid The burden can be reduced.
したがって、上述した第１の実施の形態によれば、粉末状活性炭とバインダーとからなる活性炭５８のバインダーの含有量を０．１〜２質量％とすることで、従来の成型活性炭と比較してバインダーの含有量を低減することができるため、成型活性炭のトリハロメタン吸着性能を十分に確保しつつ小型化をはかることができる。 Therefore, according to 1st Embodiment mentioned above, by making the content of the binder of the activated carbon 58 which consists of powdered activated carbon and a binder into 0.1-2 mass%, compared with the conventional shaping | molding activated carbon. Since the binder content can be reduced, downsizing can be achieved while sufficiently securing the trihalomethane adsorption performance of the molded activated carbon.
活性炭５８とケース１３の蓋体１３ｂとの間には、第１の実施の形態と同様にクッション材６１が介装されている。つまり、吸着部４３ｂは、クッション材６１とクッション材８６とによって挟まれることとなり、活性炭５８が軸方向両側から付勢される。したがって、活性炭５８の軸方向へ膨潤による変形分がクッション材６１とクッション材８６との両方で吸収される。クッション材６１，８６は、弾性体であれば、例えばイソプレン、アクリルなどからなる合成ゴムの成形体などを用いてもよく、また、円盤状に限られるものではない。なお、上述した支持部５４は、弾性体を介して吸着部４３ｂを支持できる形状であればよく、例えば、壁部８４を周壁部８５の外側に配置してもよい。なお、カートリッジの小型化を優先する場合は、クッション材８６を設ける際に、図１０に示すように、クッション材６１を省略しても本発明の効果は得られるが、先に示した第２の実施の形態のように、クッション材６１とクッション材８６とで吸着部４３ｂが上下から略均等に付勢されているほうが、成型活性炭の形状安定の面からは好ましい。 A cushion material 61 is interposed between the activated carbon 58 and the lid 13b of the case 13 as in the first embodiment. That is, the adsorbing portion 43b is sandwiched between the cushion material 61 and the cushion material 86, and the activated carbon 58 is urged from both axial sides. Therefore, the deformation due to swelling in the axial direction of the activated carbon 58 is absorbed by both the cushion material 61 and the cushion material 86. As long as the cushion materials 61 and 86 are elastic bodies, for example, a synthetic rubber molded body made of isoprene, acrylic, or the like may be used. Note that the above-described support portion 54 may be in any shape that can support the suction portion 43b via an elastic body. If priority is given to downsizing of the cartridge, the effect of the present invention can be obtained even when the cushion material 61 is omitted as shown in FIG. As in the above embodiment, it is preferable from the standpoint of shape stability of the molded activated carbon that the suction portion 43b is biased substantially uniformly from above and below by the cushion material 61 and the cushion material 86.
