　無機剤カートリッジ６は、活性炭カートリッジ５では吸着除去仕切れなかった濁質成分を吸着して除去する。実施例１に係る浄水装置２０では、膜カートリッジ７のケース７ａ内に充填される無機浄化剤６ｂとして、少なくともアルミナを含んだ混合物を用いており、これにより水中に陰イオンとして存在するヒ素やフッ素を除去することができる。無機浄化剤６ｂとしては、アルミナ、酸化チタン、酸化タングステン、酸化亜鉛、銅、銅を含む合金、銀、銀を含む合金、白金、白金を含む合金のうちの少なくともひとつを含むことが好ましい。無機浄化剤６ｂは、１ミクロン未満の粉状のものが用いられる。 The inorganic agent cartridge 6 adsorbs and removes suspended matter components that were not adsorbed and removed by the activated carbon cartridge 5. In the water purifier 20 according to the first embodiment, a mixture containing at least alumina is used as the inorganic cleaning agent 6b to be filled in the case 7a of the membrane cartridge 7, whereby arsenic and fluorine present as anions in water Can be removed. The inorganic purification agent 6b preferably contains at least one of alumina, titanium oxide, tungsten oxide, zinc oxide, copper, an alloy containing copper, silver, an alloy containing silver, platinum, and an alloy containing platinum. As the inorganic cleaning agent 6b, powdery one less than 1 micron is used.
　膜カートリッジ７は、上記３つのカートリッジで除去仕切れなかった濁質成分を、濾過膜としての中空糸膜７ｂによって膜濾過する。すなわち、細いストロー状の中空糸膜７ｂが多数束ねられて略Ｕ字状に湾曲させた状態で膜カートリッジ７のケース７ａ内部に収容される。そして、原水が中空糸膜７ｂの膜壁を通過する際に、原水に含まれる濁質成分が中空糸膜７ｂによって濾過される。 The membrane cartridge 7 carries out membrane filtration of the suspended matter components not removed and separated by the above three cartridges by the hollow fiber membrane 7b as a filtration membrane. That is, a large number of thin straw-like hollow fiber membranes 7b are bundled and accommodated in the inside of the case 7a of the membrane cartridge 7 in a state of being curved in a substantially U shape. Then, when the raw water passes through the membrane wall of the hollow fiber membrane 7b, the turbid component contained in the raw water is filtered by the hollow fiber membrane 7b.
　このように、実施例１に係る浄水装置２０は、浄化部としての無機剤カートリッジ６の下流側に、無機剤カートリッジ６とは別体で、膜濾過部としての膜カートリッジ７を設ける。このような構成により、上流側で除去仕切れなかった原水に含まれる濁質成分は勿論のこと、例えば、無機剤カートリッジ６に充填された無機浄化剤６ｂが下流側に流出してしまった場合にも、無機剤カートリッジ６の下流側に配置された膜カートリッジ７で捕捉することができるため、安全である。 As described above, the water purifier 20 according to the first embodiment has the membrane cartridge 7 as the membrane filtration unit separately from the inorganic agent cartridge 6 on the downstream side of the inorganic agent cartridge 6 as the purification unit. With such a configuration, suspended components contained in the raw water not removed and separated on the upstream side as well as, of course, when the inorganic cleaning agent 6b filled in the inorganic agent cartridge 6 has flowed out to the downstream side It is also safe because it can be captured by the membrane cartridge 7 disposed downstream of the inorganic agent cartridge 6.
　そして、膜カートリッジ７の中空糸膜７ｂを通過した水は浄水となって主通路３１の下流側に供給される。膜カートリッジ７の下流側の主通路３１には、上流側から下流側に向かって順に、水質センサ８、流量センサ９、吐出弁１０および浄水吐出口１２が直列に配置される。 Then, the water that has passed through the hollow fiber membrane 7 b of the membrane cartridge 7 is supplied to the downstream side of the main passage 31 as purified water. In the main passage 31 on the downstream side of the membrane cartridge 7, the water quality sensor 8, the flow rate sensor 9, the discharge valve 10, and the purified water discharge port 12 are arranged in series in this order from the upstream side to the downstream side.
　また、実施例１に係る浄水装置２０は、活性炭カートリッジ５と無機剤カートリッジ６との間および無機剤カートリッジ６と膜カートリッジ７との間に、それぞれ洗浄通路３１ａ、３１ｂを接続して設ける。このような構成により、無機剤カートリッジ６のケース６ａ内部にある無機浄化剤６ｂを洗浄することができる。 Further, the water purifier 20 according to the first embodiment is provided by connecting the cleaning passages 31 a and 31 b between the activated carbon cartridge 5 and the inorganic agent cartridge 6 and between the inorganic agent cartridge 6 and the membrane cartridge 7 respectively. With such a configuration, the inorganic cleaning agent 6 b in the case 6 a of the inorganic agent cartridge 6 can be cleaned.
　具体的な洗浄方法の一例としては、まず、逆止弁１６と吐出弁１０とを閉めることによって水の流れを止めるとともに、注入弁１４と排出弁１１とを開くことによって薬品注入口１５から注入された洗浄液を主通路３１に流す。この際、図１では図示省略したが、主通路３１と洗浄通路３１ａの接続部３１ｄおよび主通路３１と洗浄通路３１ｂの接続部３１ｃには、それぞれ分岐弁が設けられる。これら２つの分岐弁によって、洗浄液が洗浄通路３１ａから無機剤カートリッジ６と洗浄通路３１ｂとの順に導かれて、排出口１３から排出される。そして、排出口１３から洗浄液が充分に流出したことを確認して排出弁１１を閉めるとともに、注入弁１４を閉めて洗浄液の注入を停止する。そして、所定時間を空けた後に排出弁１１を再度開くとともに、逆止弁１６を開くことによって主通路３１、無機剤カートリッジ６および洗浄通路３１ｂ内に残余した洗浄液を水で洗浄する。このような作業は、作業者が行ってもよいし、自動的に行うように構成してもよい。 As an example of the specific cleaning method, first, the flow of water is stopped by closing the check valve 16 and the discharge valve 10, and the injection is performed from the chemical inlet 15 by opening the injection valve 14 and the discharge valve 11. The cleaning solution is flowed to the main passage 31. At this time, although not shown in FIG. 1, branch valves are respectively provided at the connection portion 31d of the main passage 31 and the washing passage 31a and at the connection portion 31c of the main passage 31 and the washing passage 31b. The cleaning liquid is guided from the cleaning passage 31 a in order of the inorganic agent cartridge 6 and the cleaning passage 31 b by these two branch valves, and is discharged from the discharge port 13. Then, after confirming that the cleaning liquid has sufficiently flowed out from the discharge port 13, the discharge valve 11 is closed, and the injection valve 14 is closed to stop the injection of the cleaning liquid. Then, after leaving the predetermined time, the discharge valve 11 is opened again, and the check valve 16 is opened to wash the washing liquid remaining in the main passage 31, the inorganic agent cartridge 6 and the washing passage 31b with water. Such work may be performed by a worker or may be performed automatically.
　このように、実施例１に係る浄水装置２０は、浄水通路３に洗浄通路３１ａ、３１ｂを設けることで、無機剤カートリッジ６の無機浄化剤６ｂを洗浄可能としている。そして、洗浄液により無機浄化剤６ｂに吸着された濁質成分を除去することで、無機浄化剤６ｂを繰り返し使用できるようにしている。なお、洗浄液としては、無機浄化剤６ｂの種類によって適宜に選択可能であるが、例えば、水酸化ナトリウム、炭酸ナトリウム、炭酸水素ナトリウム、水酸化カルシウム、水酸化カリウム、クエン酸、シュウ酸、炭酸、ホウ酸、塩酸、酢酸、界面活性剤、次亜塩素酸ナトリウム、二酸化塩素などを用いることができる。実施例１に係る浄水装置２０では、無機浄化剤６ｂとして少なくともアルミナを用いている。このため、洗浄液として炭酸水素ナトリウム、クエン酸等を用いることで、アルミナを洗浄するとともに再び再生させて利用することができる。 Thus, the water purifier 20 according to the first embodiment can clean the inorganic purification agent 6 b of the inorganic agent cartridge 6 by providing the cleaning passages 31 a and 31 b in the water purification passage 3. Then, the inorganic cleaning agent 6b can be repeatedly used by removing the suspended matter components adsorbed to the inorganic cleaning agent 6b by the cleaning liquid. The cleaning solution can be appropriately selected depending on the type of the inorganic cleaning agent 6b, and examples thereof include sodium hydroxide, sodium carbonate, sodium hydrogencarbonate, calcium hydroxide, potassium hydroxide, citric acid, oxalic acid, carbonic acid, Boric acid, hydrochloric acid, acetic acid, surfactants, sodium hypochlorite, chlorine dioxide and the like can be used. In the water purifier 20 which concerns on Example 1, at least alumina is used as the inorganic purification agent 6b. Therefore, by using sodium hydrogen carbonate, citric acid or the like as the cleaning liquid, alumina can be cleaned and regenerated again for use.
　以上説明したように、実施例１に係る浄水装置２０によれば、ケース６ａの内部に無機浄化剤６ｂを充填させた無機剤カートリッジ６の下流側に、無機剤カートリッジ６とは別体で膜カートリッジ７を設ける。そのため、水中の濁質成分に応じて無機浄化剤６ｂを変更したい場合には、無機剤カートリッジ６のみを取りはずして交換すればよい。その結果、装置としてのメンテナンスや管理を容易に行うことができる。 As described above, according to the water purifier 20 according to the first embodiment, a film separate from the inorganic agent cartridge 6 on the downstream side of the inorganic agent cartridge 6 in which the case 6a is filled with the inorganic purification agent 6b. A cartridge 7 is provided. Therefore, when it is desired to change the inorganic cleaning agent 6b in accordance with the turbid substance in water, only the inorganic agent cartridge 6 may be removed and replaced. As a result, maintenance and management as an apparatus can be easily performed.
　また、実施例１に係る浄水装置２０では、無機浄化剤６ｂが、アルミナ、酸化チタン、酸化タングステン、酸化亜鉛、銅、銅を含む合金、銀、銀を含む合金、白金、白金を含む合金のうちの少なくともひとつを含む。このため、無機浄化剤６ｂが殺菌機能を発揮して、水中に存在する濁質成分を除去することができる。 In the water purifier 20 according to the first embodiment, the inorganic purification agent 6 b is alumina, titanium oxide, tungsten oxide, zinc oxide, copper, an alloy containing copper, silver, an alloy containing silver, platinum, an alloy containing platinum Includes at least one of them. For this reason, the inorganic purification agent 6b can exhibit a sterilizing function, and can remove the turbid substance which exists in water.
　特に、実施例１に係る浄水装置２０では、ケース７ａ内に充填される無機浄化剤６ｂとして、少なくともアルミナを含んだ混合物を用いているため、水中に陰イオンとして存在するヒ素やフッ素を除去することができる。 In particular, in the water purifier 20 according to the first embodiment, since a mixture containing at least alumina is used as the inorganic purifying agent 6b filled in the case 7a, arsenic and fluorine existing as anions in water are removed be able to.
　更に、実施例１に係る浄水装置２０では、浄化部としての無機剤カートリッジ６を洗浄することの可能な洗浄通路３１ａ、３１ｂを設けたため、無機浄化剤６ｂを洗浄して繰り返し使用することができる。その結果、無機剤カートリッジ６の寿命を延ばすことができるとともに、廃棄物を減らすことができる。 Furthermore, in the water purifier 20 according to the first embodiment, since the cleaning passages 31a and 31b capable of cleaning the inorganic agent cartridge 6 as the purification unit are provided, the inorganic purification agent 6b can be cleaned and used repeatedly. . As a result, the life of the inorganic agent cartridge 6 can be extended, and waste can be reduced.
　更にまた、実施例１に係る浄水装置２０では、洗浄通路３１ａ、３１ｂが無機剤カートリッジ６を独立して洗浄できるように設けられているため、プレフィルターカートリッジ４、活性炭カートリッジ５、膜カートリッジ７に影響を及ぼすことなく無機浄化剤６ｂを洗浄することができる。その結果、洗浄液のコンタミによるその他のカートリッジの劣化を抑制することができるとともに、洗浄液の使用量を最小限に抑えることができるという利点もある。 Furthermore, in the water purifier 20 according to the first embodiment, the washing passages 31a and 31b are provided so as to be able to wash the inorganic agent cartridge 6 independently, so the prefilter cartridge 4, the activated carbon cartridge 5, and the membrane cartridge 7 can be used. The inorganic cleaning agent 6b can be washed without any influence. As a result, it is possible to suppress the deterioration of the other cartridges due to the contamination of the cleaning solution, and to minimize the amount of the cleaning solution used.
　実施例２に係る浄水装置２０Ａは、図２に示すように、上記実施例１と同様にして、上水配管１に分岐管２を介して浄水通路３が接続される。そして、上水配管１を流通する原水としての水道水が浄水通路３を通過する間に浄化され、浄化された水道水が浄水として浄水吐出口１２から吐出される。 In the water purifier 20A according to the second embodiment, as shown in FIG. 2, the water purification passage 3 is connected to the upper water pipe 1 via the branch pipe 2 in the same manner as the first embodiment. And, while the tap water as the raw water which circulates the drinking water piping 1 passes through the clean water passage 3, the purified tap water is discharged from the clean water discharge port 12 as the purified water.
　ここで、実施例２が上記実施例１と主に異なる点は、膜カートリッジ７Ａが、表面に無機浄化剤６ｂがコーティングされた中空糸膜７ｂにより構成されたことにある。また、実施例２では、洗浄通路３１ａ、３１ｂが設けられていない。 Here, the second embodiment is mainly different from the first embodiment in that the membrane cartridge 7A is constituted of a hollow fiber membrane 7b whose surface is coated with the inorganic purification agent 6b. Further, in the second embodiment, the cleaning passages 31a and 31b are not provided.
　膜カートリッジ７Ａとしては、例えば、無機浄化剤６ｂの粒子が入った溶液を中空糸膜７ｂに通水することで無機浄化剤６ｂの粒子を中空糸膜７ｂ上に積層することができる。 As the membrane cartridge 7A, for example, particles of the inorganic cleaning agent 6b can be laminated on the hollow fiber membrane 7b by passing a solution containing particles of the inorganic cleaning agent 6b through the hollow fiber membrane 7b.
　以上の構成の実施例２に係る浄水装置２０Ａによっても、上記実施例１に係る浄水装置２０と同様の作用効果を得ることができる。すなわち、実施例２に係る浄水装置２０では、水中の濁質成分に応じて無機浄化剤６ｂを変更したい場合には、浄水通路３から膜カートリッジ７Ａを取りはずして、中空糸膜７ｂをコーティングする無機浄化素材６ｂを変更すればよい。その結果、メンテナンスや管理を容易に行うことができる。 Also with the water purifier 20A according to the second embodiment having the above configuration, the same function and effect as the water purifier 20 according to the first embodiment can be obtained. That is, in the water purifier 20 according to the second embodiment, when it is desired to change the inorganic purification agent 6b according to the suspended matter component in water, the membrane cartridge 7A is removed from the water purification passage 3 to coat the hollow fiber membrane 7b. What is necessary is just to change the purification material 6b. As a result, maintenance and management can be easily performed.
　実施例３に係る浄水装置２０Ｂは、図３に示すように、上記実施例１と同様にして、上水配管１に分岐管２を介して浄水通路３が接続される。そして、上水配管１を流通する原水としての水道水が浄水通路３を通過する間に浄化され、浄化された水道水が浄水として浄水吐出口１２から吐出される。 In the water purifier 20B according to the third embodiment, as shown in FIG. 3, the water purification passage 3 is connected to the upper water pipe 1 via the branch pipe 2 in the same manner as the first embodiment. And, while the tap water as the raw water which circulates the drinking water piping 1 passes through the clean water passage 3, the purified tap water is discharged from the clean water discharge port 12 as the purified water.
　ここで、実施例３が上記実施例１と主に異なる点は、活性炭カートリッジ５に換えて、無機浄化剤１７ｂとして酸化チタンまたは酸化タングステンの少なくと一方を含んだ混合物を充填した無機剤カートリッジ１７を更に配置させたことにある。 Here, the point that Example 3 mainly differs from the above Example 1 is that instead of the activated carbon cartridge 5, an inorganic agent cartridge 17 filled with a mixture containing at least one of titanium oxide or tungsten oxide as the inorganic cleaning agent 17b. It is because I was arranged more.
　無機剤カートリッジ１７は、無機浄化剤１７ｂが内部に充填されたケース１７ａと光源ランプ１８とを備える。そして、光源ランプ１８の光を無機浄化剤１７ｂに当てることによって、無機浄化剤１７ｂが光触媒機能を発揮しする。この結果、臭い成分や残留塩素を除去して、殺菌作用を得ることができる。 The inorganic agent cartridge 17 includes a case 17 a filled with the inorganic cleaning agent 17 b and a light source lamp 18. Then, the light of the light source lamp 18 is applied to the inorganic purification agent 17b, whereby the inorganic purification agent 17b exhibits a photocatalytic function. As a result, odorous components and residual chlorine can be removed to obtain a bactericidal action.
　なお、光源ランプ１８としては、例えば、紫外線ランプ、紫外線発光ダイオード、可視光ランプなどを用いることができる。 As the light source lamp 18, for example, an ultraviolet lamp, an ultraviolet light emitting diode, a visible light lamp or the like can be used.
　以上の構成の実施例３に係る浄水装置２０Ｂによっても、上記実施例１に係る浄水装置２０と同様の作用効果を得ることができるとともに、光触媒機能により雑菌が繁殖してしまうことを抑制できるため、より衛生的である。 Also by the water purifier 20B according to the third embodiment having the above configuration, the same function and effect as the water purifier 20 according to the first embodiment can be obtained, and breeding of bacteria due to the photocatalytic function can be suppressed. And more hygienic.
　また、上記無機浄化剤１７ｂとして酸化タングステンを含んだ混合物を用いた場合には、紫外線ランプを用いる必要がなくなり、コストを低減することができるという利点もある。 When a mixture containing tungsten oxide is used as the inorganic cleaning agent 17b, it is not necessary to use an ultraviolet lamp, and there is also an advantage that the cost can be reduced.
　なお、図３に示した実施例３に係る浄水装置２０Ｂでは、無機剤カートリッジ１７と無機剤カートリッジ６との間の主通路３１に洗浄通路３１ａを接続して設けたが、プレフィルターカートリッジ４と無機剤カートリッジ１７との間の主通路３１に浄水通路３１ａを接続して設ける方がより好ましい。 In the water purifier 20B according to the third embodiment shown in FIG. 3, the cleaning passage 31 a is connected to the main passage 31 between the inorganic agent cartridge 17 and the inorganic agent cartridge 6. More preferably, the purified water passage 31 a is connected to the main passage 31 between the inorganic agent cartridge 17.
