[0001] 本発明は、原水中に含まれた分離対象物を逆浸透膜により分離，除去して浄水にする浄水器に関する。 The present invention relates to a water purifier that separates and removes a separation object contained in raw water by a reverse osmosis membrane to obtain purified water.

背景技術 Background art

[0002] 従来、浄水器として、例えば、特開平 9— 299933号公報に開示されたものが知られている。この浄水器は、上部が開口し、原水が貯水される貯水タンクと、貯水タンクの上部に着脱自在に取り付けられ、貯水タンクの上部開口部を閉塞する蓋体と、蓋体の下面に着脱自在に取り付けられて、貯水タンク内の原水中に配置される濾過槽と、蓋体に設けられ、貯水タンク内の原水を濾過槽内に供給するポンプなど力構成される。 Conventionally, as a water purifier, for example, one disclosed in Japanese Patent Laid-Open No. 9-299933 is known. This water purifier is open at the top, a water storage tank that stores raw water, a lid that is detachably attached to the top of the water storage tank, a lid that closes the top opening of the water storage tank, and a detachable on the bottom surface of the lid Attached to the filter tank and disposed in the raw water in the water storage tank, and a pump provided on the lid for supplying the raw water in the water storage tank into the filter tank.

[0003] 前記蓋体は、内部が中空に形成されており、この中空部内に前記ポンプが配設される。また、蓋体には、濾過槽の内部を流通した原水を外部に吐出するための吐出口が形成されており、この吐出口には、濾過槽の原水流通方向下流側に一端側が接続された流通管の他端側が接続されている。また、更に、この蓋体には、ポンプを駆動させるための押しボタンが設けられている。 [0003] The lid has a hollow interior, and the pump is disposed in the hollow portion. Also, the lid is formed with a discharge port for discharging the raw water flowing through the inside of the filtration tank to the outside, and one end side is connected to the discharge port on the downstream side in the raw water flow direction of the filtration tank. The other end side of the flow pipe is connected. Further, the lid is provided with a push button for driving the pump.

[0004] 前記濾過槽は、活性炭層，ミネラル添加層及び中空糸膜層の 3つの処理層を備え、ポンプによって供給された原水が活性炭層，ミネラル添加層及び中空糸膜層を順次流通するように構成されており、原水は、活性炭層において脱臭 (カルキ臭の除去など)されたり、有害な化学物質が除去され、ミネラル添加層においてミネラル分が添加され、中空糸膜層において、前記活性炭層で除去されな力た不純物などが除去される。 [0004] The filtration tank includes three treatment layers, an activated carbon layer, a mineral addition layer, and a hollow fiber membrane layer, and raw water supplied by a pump sequentially flows through the activated carbon layer, the mineral addition layer, and the hollow fiber membrane layer. The raw water is deodorized in the activated carbon layer (removal of odor of lime, etc.), harmful chemical substances are removed, minerals are added in the mineral addition layer, and the hollow fiber membrane layer Powerful impurities that are not removed by the activated carbon layer are removed.

[0005] 前記ポンプは、貯水タンクの底部に向力つて伸びる吸水管と、濾過槽の原水流通方向上流側に接続された供給管とを備えており、吸水管から吸い込んだ原水を供給管を介して濾過槽の内部に供給し、濾過槽の内部を流通後、流通管内を流通させて吐出口から吐出させる。 [0006] この浄水器によれば、まず、貯水タンクから蓋体がー且取り外され、この貯水タンク内に原水 (例えば水道水）が入れられた後、蓋体が再び貯水タンクに取り付けられる。この後、蓋体の押しボタンが押されてポンプが駆動せしめられると、貯水タンク内の原水は、濾過槽内部の活性炭層，ミネラル添加層及び中空糸膜層を順次流通して有害物質や不純物などが除去されるとともにミネラル分が添加されて、成分調整された浄水とされ、流通管内を流通して蓋体の吐出口から外部に吐出される。 [0005] The pump includes a water suction pipe extending toward the bottom of the water storage tank and a supply pipe connected to the upstream side in the raw water circulation direction of the filtration tank, and the raw water sucked from the water suction pipe is provided with the supply pipe. Then, the liquid is supplied to the inside of the filtration tank, and after flowing through the inside of the filtration tank, it is circulated through the flow pipe and discharged from the outlet. [0006] According to this water purifier, the lid is first removed from the water storage tank, and after the raw water (for example, tap water) is put into the water storage tank, the lid is attached to the water storage tank again. After that, when the push button on the lid is pushed and the pump is driven, the raw water in the water storage tank flows through the activated carbon layer, mineral addition layer, and hollow fiber membrane layer in the filtration tank in order, and harmful substances and impurities. Etc. are removed and minerals are added to obtain purified water with adjusted components, which are circulated through the distribution pipe and discharged to the outside from the discharge port of the lid.

発明が解決しょうとする課題 Problems to be solved by the invention

[0008] し力しながら、上記従来の浄水器では、貯水タンク内に原水を入れるのに蓋体の取り外し及び取り付けを行わなければならず、面倒であるという問題があった。また、蓋体には、濾過槽、ポンプの吸水管や供給管が外部に露出した状態で取り付けられているので、蓋体を貯水タンクから取り外すと、取り扱いに注意しなければならないという問題や、誤って濾過槽，吸水管及び供給管を何かにぶつけると、当該濾過槽，吸水管及び供給管が破損する恐れがあるという問題もある。 [0008] However, the conventional water purifier has a problem that it is troublesome to remove and attach the lid in order to put the raw water into the water storage tank. Also, since the lid is attached with the filtration tank, pump water intake pipe and supply pipe exposed to the outside, there is a problem that care must be taken when handling the lid when it is removed from the water storage tank. There is also a problem that if the filtration tank, the water absorption pipe and the supply pipe are accidentally bumped into something, the filtration tank, the water absorption pipe and the supply pipe may be damaged.

[0009] また、更に、濾過槽の内部が外部と流通管及び蓋体の吐出口を介して常に連通状態となつているので、空気中の雑菌がこの吐出口及び流通管から濾過槽の内部に侵入して繁殖し、当該濾過槽の内部が汚染されるという問題や、濾過槽の内部が汚染されること〖こよって、活性炭層，ミネラル添加層及び中空糸膜層の各処理機能が低下したり、この濾過槽内を流通し吐出口から吐出される浄水に雑菌が含まれるという問題もある。 [0009] Furthermore, since the inside of the filtration tank is always in communication with the outside via the flow pipe and the discharge port of the lid, various germs in the air pass from the discharge port and the flow pipe to the filtration tank. Each of the treatment functions of the activated carbon layer, mineral-added layer, and hollow fiber membrane layer due to the problem that the inside of the filtration tank is contaminated by invading and breeding, and the inside of the filtration tank is contaminated. There is also a problem that germs are contained in the purified water that flows through the filtration tank and is discharged from the discharge port.

[0010] 本発明は、以上の実情に鑑みなされたものであって、取り扱いが簡単であり、雑菌の侵入を防止することができる浄水器の提供をその目的とする。 [0010] The present invention has been made in view of the above circumstances, and an object thereof is to provide a water purifier that is easy to handle and can prevent invasion of germs.

課題を解決するための手段 Means for solving the problem

[0011] 上記目的を達成するための本発明は、 [0011] To achieve the above object, the present invention provides:

原水中に含まれた分離対象物を分離，除去する浄水器であって、 A water purifier that separates and removes separation objects contained in raw water,

給水弁を具備した給水機構を底部に備え、前記原水が貯留される貯留容器と、逆浸透膜を備え、この逆浸透膜により前記原水力も前記分離対象物を分離する膜分離手段と、 A water supply mechanism having a water supply valve at the bottom, a storage container for storing the raw water, a reverse osmosis membrane, and a membrane that also separates the separation target by the reverse osmosis membrane Separating means;

一端側が前記膜分離手段に接続された供給管を備え、この供給管を介し、前記貯留容器内の原水を加圧して前記膜分離手段に供給する供給手段と、 A supply unit having one end connected to the membrane separation unit, through which the raw water in the storage container is pressurized and supplied to the membrane separation unit;

一端側が前記膜分離手段に接続され、前記逆浸透膜を透過した原水たる浄水が流通する浄水流通管と、 One end side is connected to the membrane separation means, and a purified water distribution pipe through which purified water that is raw water that has passed through the reverse osmosis membrane flows,

一端側が前記膜分離手段に接続され、前記逆浸透膜を透過しなカゝつた原水たる排水が流通する排水流通管と、 A drainage distribution pipe having one end side connected to the membrane separation means and through which drainage as raw water that does not pass through the reverse osmosis membrane flows;

前記貯留容器が上面に載置される載置部と、前記載置部上に配設されて前記給水機構と着脱自在に接続し、前記供給管の他端側が接続される接続部材と、前記浄水流通管の他端側が接続され、前記浄水を外部に吐出するための吐出口と、前記排水流通管の他端側が接続され、前記排水を外部に排出するための排出口とを備え、前記膜分離手段，供給手段，浄水流通管及び排水流通管が内蔵される本体とからなり、 A mounting portion on which the storage container is mounted; a connecting member that is disposed on the mounting portion and is detachably connected to the water supply mechanism; and the other end of the supply pipe is connected; The other end side of the purified water distribution pipe is connected, and a discharge port for discharging the purified water to the outside, and a discharge port for connecting the other end side of the drainage distribution pipe and discharging the drainage to the outside are provided. The membrane separation means, the supply means, the purified water distribution pipe and the main body containing the drainage distribution pipe,

前記給水弁は、前記給水機構と前記接続部材とが接続するように前記貯留容器が前記載置部上に載置されたときにこの接続部材によって開かれ、この給水弁が開かれると、前記貯留容器の内部と前記供給管の他端側とが連通状態となるように構成されてなることを特徴とする浄水器に係る。 The water supply valve is opened by the connection member when the storage container is placed on the mounting portion so that the water supply mechanism and the connection member are connected, and when the water supply valve is opened, The present invention relates to a water purifier, characterized in that the inside of a storage container and the other end side of the supply pipe are in communication with each other.

[0012] この発明によれば、まず、貯留容器の給水機構と本体の載置部上の接続部材との接続が解除されるように貯留容器が載置部上カゝら取り外されて、例えば、水道水などの原水が貯留容器内に入れられた後、給水機構と接続部材とが接続するように貯留容器が載置部上に載置される。このとき、給水機構の給水弁が接続部材によって開かれるとともに、給水弁が開くことで、貯留容器の内部と供給手段の供給管の他端側とが連通状態となる。 [0012] According to this invention, first, the storage container is removed from the mounting portion so that the connection between the water supply mechanism of the storage container and the connection member on the mounting portion of the main body is released, for example, Then, after raw water such as tap water is placed in the storage container, the storage container is placed on the placement part so that the water supply mechanism and the connection member are connected. At this time, the water supply valve of the water supply mechanism is opened by the connecting member, and the water supply valve is opened so that the inside of the storage container and the other end of the supply pipe of the supply means are in communication.

[0013] この後、供給手段が適宜駆動されると、この供給手段により、貯留容器内の原水が、供給管を介し、加圧されて膜分離手段に供給される。そして、逆浸透膜を透過した原水は、浄水流通管内を流通し、分離対象物の分離された浄水として本体の吐出口力も外部に吐出され、逆浸透膜を透過しな力つた原水は、排水流通管内を流通し、排水として本体の排出ロカ外部に排出される。尚、吐出口から吐出された浄水は、適宜容器に貯留されるようになってヽる。 [0013] Thereafter, when the supply unit is appropriately driven, raw water in the storage container is pressurized by the supply unit through the supply pipe and supplied to the membrane separation unit. The raw water that has passed through the reverse osmosis membrane flows through the purified water distribution pipe, and the outlet of the main body is also discharged to the outside as the purified water from which the separation object is separated. It circulates in the distribution pipe and is discharged to the outside as the waste water of the main body. The purified water discharged from the discharge port is Store in containers as appropriate.

[0014] このように、本発明に係る浄水器によれば、使用者は、貯留容器内に原水を入れて、給水機構と載置部上の接続部材とが接続するように貯留容器を載置部上に載置するだけで良ぐ従来の浄水器のように蓋体の着脱作業を行う必要がないので、簡単に使用することができる。また、膜分離手段，供給手段，浄水流通管及び排水流通管が本体に内蔵されており、貯留容器のみを本体の載置部上に載置したり、載置部上力も取り外せば良いので、取り扱いが簡単である。また、更に、膜分離手段，供給手段，浄水流通管及び排水流通管を本体に内蔵することで、装置構成のコンパクトィ匕を図り、持ち運びに適したものとすることもできる。 As described above, according to the water purifier of the present invention, the user puts the raw water into the storage container and mounts the storage container so that the water supply mechanism and the connection member on the mounting portion are connected. Unlike conventional water purifiers that only need to be placed on the mounting section, it is not necessary to attach or detach the lid, so it can be used easily. In addition, membrane separation means, supply means, purified water distribution pipe and drainage distribution pipe are built in the main body, so that only the storage container can be mounted on the mounting section of the main body or the mounting section upper force can be removed. Easy to handle. Further, by incorporating the membrane separation means, supply means, purified water distribution pipe and drainage distribution pipe into the main body, the apparatus configuration can be made compact and suitable for carrying.

[0015] 尚、前記浄水器は、前記浄水流通管に設けられ、その一端側力も他端側に向けてのみ前記浄水を流通させる逆止弁を更に備えて構成されて、ても良ヽ。このようにすれば、浄水流通管内を浄水が流通していないときは、この逆止弁によって管路を閉塞することができ、空気中の雑菌が浄水流通管及び本体の吐出口から膜分離手段の内部に侵入するのを防止することができる。これにより、逆浸透膜が汚染されたり、逆浸透膜の分離，除去機能が低下したり、吐出口から吐出される浄水に雑菌が含まれるのを効果的に防止することができる。 [0015] The water purifier may be further provided with a check valve that is provided in the water purifying flow pipe and that has one end side force flowing only toward the other end side. In this way, when the purified water is not circulating in the purified water distribution pipe, the check line can close the pipeline, and germs in the air can pass through the purified water distribution pipe and the discharge port of the main body. Intrusion into the separation means can be prevented. Thereby, it is possible to effectively prevent the reverse osmosis membrane from being contaminated, the function of separating and removing the reverse osmosis membrane from being deteriorated, and germs from being contained in the purified water discharged from the discharge port.

発明の効果 The invention's effect

[0016] 斯くして、本発明に係る浄水器によれば、取り扱いが簡単で使い勝手が良いだけでなぐコンパクト且つ持ち運びに便利なものとしたり、吐出ロカも侵入した雑菌によつて逆浸透膜が汚染されるのを防止して衛生的に優れた浄水を吐出ロカ吐出させることができる。 [0016] Thus, according to the water purifier according to the present invention, the reverse osmosis membrane can be used because it is easy to handle and easy to use, and is compact and convenient to carry. It is possible to prevent contaminated water and to discharge clean water that is hygienic and excellent.

The power supply pump 31 is operated for a set time by the user turning the knob 46 of the timer switch.

[0038] 以上のように構成された本例の浄水器 1によれば、まず、給水機構 12の給水部材 1 3が接続部材 42から取り外されるように容器本体 11が載置部 41b上から取り上げられ、原水（水道水) Lが容器本体 11内に入れられる。このとき、給水弁 14は、ばね体 18の付勢力によって係合部材 17が下方に付勢され、封止部材 16によって貫通穴 1 3aを上側力封止して、る。 [0038] According to the water purifier 1 of the present example configured as described above, first, the container body 11 is taken up from the mounting portion 41b so that the water supply member 13 of the water supply mechanism 12 is removed from the connection member 42. Then, raw water (tap water) L is put into the container body 11. At this time, in the water supply valve 14, the engaging member 17 is urged downward by the urging force of the spring body 18, and the through hole 13 a is sealed with the sealing member 16 on the upper side.

[0039] この後、給水部材 13が接続部材 42に外嵌されるように容器本体 11が載置部 41b 上に載置されると、係合部材 17と係合突起 42bとが係合して係合部材 17,移動部材 15及び封止部材 16がばね体 18の付勢力に抗して上方に移動せしめられ、貫通穴 13aの封止が解除されて、容器本体 11の内部と第 1供給管 32aとが連通状態となる [0039] After that, when the container body 11 is placed on the placement portion 41b so that the water supply member 13 is externally fitted to the connection member 42, the engagement member 17 and the engagement protrusion 42b are engaged. The engaging member 17, the moving member 15 and the sealing member 16 are moved upward against the urging force of the spring body 18, the sealing of the through hole 13a is released, and the inside of the container body 11 and the first Communication with the supply pipe 32a

[0040] 次に、使用者がタイマスィッチのつまみ 46を回して作動時間を設定すると、当該設定された時間、供給ポンプ 31が作動する。これにより、容器本体 11内の原水 Lが、第 1供給管 32a,第 1フィルタ処理部 26,第 2供給管 32b,第 3供給管 32c,第 2フィルタ処理部 27及び第 4供給管 32d内を順次流通して容器体 21内に供給される。 [0040] Next, when the user sets the operating time by turning the knob 46 of the timer switch, the supply pump 31 is operated for the set time. As a result, the raw water L in the container body 11 flows into the first supply pipe 32a, the first filter processing section 26, the second supply pipe 32b, the third supply pipe 32c, the second filter processing section 27, and the fourth supply pipe 32d. Are sequentially distributed and supplied into the container body 21.

[0041] 容器体 21内に供給された原水 Lの一部は、逆浸透膜 22を透過して浄水流通管 35 内を流通し、この後、吐出部材 43の吐出口（図示せず)から浄水として吐出され、容器 5内に貯留される。一方、供給された原水 Lの残りは、逆浸透膜 22を透過せずに排水流通管 37 (第 1流通管 37a,第 2流通管 37b)内を流通し、この後、排出部材 44 の排出口（図示せず)から排水として排出される。 [0041] A part of the raw water L supplied into the container body 21 passes through the reverse osmosis membrane 22 and circulates in the purified water distribution pipe 35, and thereafter, from a discharge port (not shown) of the discharge member 43. It is discharged as purified water and stored in the container 5. On the other hand, the remainder of the supplied raw water L does not permeate the reverse osmosis membrane 22 and circulates in the drainage distribution pipe 37 (the first distribution pipe 37a and the second distribution pipe 37b). Waste water is discharged from an outlet (not shown).

[0042] このように、本例の浄水器 1によれば、使用者は、容器本体 11内に原水を入れて、給水部材 13が接続部材 42に外嵌されるように容器本体 11を載置部 4 lb上に載置するだけで良ぐ従来の浄水器のように蓋体の着脱作業を行う必要がないので、簡単に使用することができる。また、膜分離機構 20,前処理機構 25,供給機構 30,浄水流通管 35,排水流通管 37及び制御装置（図示せず)が本体 40に内蔵されており、貯留容器 10のみを本体 40の載置部 41b上に載置したり、載置部 41b上力も取り外せば良いので、取り扱いが簡単である。また、更に、膜分離機構 20,前処理機構 25 ,供給機構 30,浄水流通管 35,排水流通管 37及び制御装置 (図示せず)を本体 40 に内蔵することで、装置構成のコンパクトィ匕を図り、持ち運びに適したものとすることもできる。 Thus, according to the water purifier 1 of this example, the user puts raw water into the container body 11 and mounts the container body 11 so that the water supply member 13 is fitted on the connection member 42. Since it is not necessary to attach and detach the lid as in the case of a conventional water purifier that only needs to be placed on the 4 lb mounting section, it can be used easily. Further, the membrane separation mechanism 20, the pretreatment mechanism 25, the supply mechanism 30, the purified water distribution pipe 35, the drainage distribution pipe 37 and the control device (not shown) are built in the main body 40, and only the storage container 10 is attached to the main body 40. Place on the mounting part 41b or remove the force on the mounting part 41b It is easy to handle. Further, by incorporating a membrane separation mechanism 20, a pretreatment mechanism 25, a supply mechanism 30, a purified water distribution pipe 35, a drainage distribution pipe 37, and a control device (not shown) in the main body 40, a compact structure of the apparatus configuration can be obtained. It is possible to make it suitable for carrying.

[0043] また、浄水流通管 35に、吐出部材 43側に向けてのみ浄水を流通させる逆止弁 36 を設けたので、浄水流通管 35内を浄水が流通していないときは、この逆止弁 36によつて管路を閉塞することができ、空気中の雑菌が吐出部材 43の吐出口（図示せず）及び浄水流通管 35から容器体 21の内部に侵入するのを防止することができる。これにより、逆浸透膜 22が汚染されたり、逆浸透膜 22の分離，除去機能が低下したり、吐出部材 43の吐出口（図示せず)から吐出される浄水に雑菌が含まれるのを効果的に防止することができる。 [0043] In addition, since the check valve 36 for flowing the purified water only toward the discharge member 43 side is provided in the purified water distribution pipe 35, when the purified water is not flowing through the purified water distribution pipe 35, this check The valve 36 can block the pipe line and prevent in-air germs from entering the inside of the container body 21 from the discharge port (not shown) of the discharge member 43 and the purified water flow pipe 35. it can. As a result, the reverse osmosis membrane 22 is contaminated, the separation / removal function of the reverse osmosis membrane 22 is deteriorated, and germs are contained in the purified water discharged from the discharge port (not shown) of the discharge member 43. Can be prevented.

[0044] また、使用者がタイマスィッチのつまみ 46を回すことで設定した時間だけ供給ボンプ 31が作動するように構成したので、即ち、設定時間が経過すると、供給ポンプ 31 が停止するように構成したので、貯留容器 10内の原水 Lが無くなった後も、供給ボンプ 31が作動し続けるといった不都合を防止することもできる。 [0044] Further, since the supply pump 31 is configured to operate for a time set by the user turning the knob 46 of the timer switch, that is, the supply pump 31 is stopped when the set time elapses. Since it is configured, it is possible to prevent the inconvenience that the supply pump 31 continues to operate even after the raw water L in the storage container 10 is exhausted.

[0045] 以上、本発明の一実施形態について説明したが、本発明の採り得る具体的な態様は、何らこれに限定されるものではない。 [0045] While one embodiment of the present invention has been described above, specific embodiments that can be taken by the present invention are not limited to this.

[0046] 上例では、原水 Lを水道水としたが、これに限られるものではな、。また、給水機構 12や給水弁 13、膜分離機構 20、本体 40の構造や形状は上例のものに限定されず、また、原水 Lや浄水、排水の流路構成も上例のものに限定されるものではない。産業上の利用可能性 [0046] In the above example, the raw water L is tap water, but it is not limited to this. Also, the structure and shape of the water supply mechanism 12, the water supply valve 13, the membrane separation mechanism 20, and the main body 40 are not limited to the above examples, and the flow path configuration of raw water L, purified water, and drainage is also limited to the above examples. Is not to be done. Industrial applicability

[0047] 以上詳述したように、本発明は、原水中に含まれた分離対象物を逆浸透膜により分離，除去して浄水にする浄水器に好適に適用することができる。 [0047] As described above in detail, the present invention can be suitably applied to a water purifier that purifies water by separating and removing a separation target contained in raw water with a reverse osmosis membrane.
