Description

本発明は、浄水生成装置に関し、詳しくは、原水を利用して浄水器を水冷するようにした浄水生成装置に関する。   The present invention relates to a purified water generator, and more particularly to a purified water generator that uses raw water to cool a water purifier.

一般的に、浄水器は、活性炭などの吸着剤と、中空糸膜やセラミック膜などの濾過膜とを具備し、吸着剤によって水道水中の分子レベルの異臭味物質や有害物質を吸着除去し、濾過膜で鉄サビ、コロイド成分、細菌などを捕捉し、除去する（例えば、特許文献１参照）。   Generally, a water purifier comprises an adsorbent such as activated carbon and a filtration membrane such as a hollow fiber membrane or a ceramic membrane, and adsorbs and removes off-flavor substances and harmful substances at the molecular level in tap water. A filter membrane captures and removes iron rust, colloidal components, bacteria, and the like (see, for example, Patent Document 1).

活性炭などの吸着剤の吸着性能は温度の影響を受けやすく、単位吸着剤あたりの吸着量は、低温ほど多く、高温ほど少ない傾向がある。したがって、活性炭などの吸着剤を利用した浄水器では、低温での使用ほど浄水性能が高く、高温になるほど浄水性能が低下する傾向がある。よって、設計時に設定していた温度よりも高温になると、設計時の想定処理量よりも、吸着処理できる量が少なくなり、浄水性能を満たさなくなる。また、周囲温度が低温から高温に急激に変化すると、吸着されていた物質が吸着剤から脱離し、清浄度の低下した水が吐水されてしまう可能性もある。   The adsorption performance of an adsorbent such as activated carbon is easily affected by temperature, and the amount of adsorption per unit adsorbent tends to increase as the temperature decreases and decreases as the temperature increases. Therefore, in a water purifier using an adsorbent such as activated carbon, the water purification performance tends to be higher as it is used at a lower temperature, and the water purification performance tends to be lower as the temperature is higher. Therefore, when the temperature becomes higher than the temperature set at the time of design, the amount that can be adsorbed is smaller than the assumed amount of processing at the time of design, and the water purification performance is not satisfied. In addition, when the ambient temperature changes suddenly from low temperature to high temperature, the adsorbed substance may be desorbed from the adsorbent, and water with reduced cleanliness may be discharged.

浄水器を、例えば、気温が高い日に使用したり、また、キッチンにおいて熱を発生する調理機器や給湯器の近傍、キッチン下の収納スペースなど熱のこもりやすい場所等で使用する場合、浄水器の温度が上がり、前述したような吸着性能の低下や、吸着していた物質の放出の可能性がある。   When using a water purifier, for example, on a day with high temperatures, or when it is used near a cooking device or water heater that generates heat in the kitchen, or in a place where heat is likely to accumulate, such as a storage space under the kitchen, the water purifier As a result, there is a possibility that the adsorption performance is lowered as described above, and the adsorbed substance is released.

なお、例えば、特許文献２には、ペルチェ効果を利用した電子冷却装置で浄水器を冷却することが開示され、また、特許文献３には、圧縮式冷凍器やガス冷凍機により浄水器を冷却することが開示されているが、それら冷却手段を用いることは、省電力化や低コスト化の妨げになる。
特開平６−３３９６７６号公報 特開平１１−９０４１７号公報 特開平７−９５２号公報 For example, Patent Document 2 discloses that the water purifier is cooled by an electronic cooling device using the Peltier effect, and Patent Document 3 discloses that the water purifier is cooled by a compression refrigerator or a gas refrigerator. However, using these cooling means hinders power saving and cost reduction.

以下に、図面を参照しつつ、本発明の実施形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

［第１具体例］
図１は、本発明の第１具体例に係る浄水生成装置の構成を例示する模式図である。
本具体例に係る浄水生成装置は、主として、原水（水道水）を浄水に浄化する浄水器１０と、浄水器１０と熱交換する熱交換手段２０と、を備える。 [First example]
FIG. 1 is a schematic view illustrating the configuration of a water purification device according to a first specific example of the invention.
The water purification apparatus according to this specific example mainly includes a water purifier 10 that purifies raw water (tap water) into purified water, and a heat exchange means 20 that exchanges heat with the water purifier 10.

図２は、浄水器１０の構造を例示する模式図である。
浄水器１０は、活性炭などの吸着剤（以下、活性炭を用いた場合を例に挙げて説明する）３２と、中空糸膜フィルタ３３と、を有する。これら活性炭３２と中空糸膜フィルタ３３は、容器３１内に収容されている。活性炭３２は、例えば、トリハロメタン、カルキ臭などを吸着、除去する。中空糸膜フィルタ３３は、例えば、鉄サビ、雑菌などを捕捉する。本具体例では、前段（上流側）に活性炭３２が、後段（下流側）に中空糸膜フィルタ３３が配設されているが、それら両者の配置関係は逆であってもよく、また材料もこれら具体例には限定されない。なお、浄水器１０に、例えばアルカリイオン水の生成機能やミネラル添加機構などを付加してもよい。 FIG. 2 is a schematic view illustrating the structure of the water purifier 10.
The water purifier 10 has an adsorbent 32 such as activated carbon (hereinafter, described using an example of using activated carbon) and a hollow fiber membrane filter 33. The activated carbon 32 and the hollow fiber membrane filter 33 are accommodated in a container 31. The activated carbon 32 adsorbs and removes, for example, trihalomethane, a salty odor, and the like. The hollow fiber membrane filter 33 captures, for example, iron rust and bacteria. In this specific example, the activated carbon 32 is disposed in the front stage (upstream side), and the hollow fiber membrane filter 33 is disposed in the rear stage (downstream side). It is not limited to these specific examples. In addition, you may add the production | generation function of alkaline ion water, a mineral addition mechanism, etc. to the water purifier 10, for example.

浄水器１０の入口部４は、コネクタ５１を介して、浄水器１０に原水を導入するための導入流路２に接続されている。導入流路２の途中には、開閉弁（電磁弁）３６が設けられている。   The inlet portion 4 of the water purifier 10 is connected to an introduction flow path 2 for introducing raw water into the water purifier 10 via a connector 51. An opening / closing valve (electromagnetic valve) 36 is provided in the middle of the introduction flow path 2.

浄水器１０の出口部６は、コネクタ５２を介して、浄水器１０で浄化した浄水を吐水するための吐水流路８に接続されている。吐水流路８の途中には、開閉弁２３が設けられている。本具体例の浄水生成装置は、いわゆる「先止め式」の浄水生成装置であり、使用者は、浄水を使用する際には、開閉弁２３を開く。ここで、開閉弁２３は、手動式のバルブでもよく、電気信号により開閉する電磁弁でもよい。   The outlet portion 6 of the water purifier 10 is connected to a water discharge channel 8 for discharging the purified water purified by the water purifier 10 via a connector 52. An opening / closing valve 23 is provided in the middle of the water discharge channel 8. The water purification device of this specific example is a so-called “first stop type” water purification device, and the user opens the on-off valve 23 when using the water. Here, the on-off valve 23 may be a manual valve or an electromagnetic valve that opens and closes by an electrical signal.

導入流路２の途上であって、開閉弁３６よりも上流側の部分からは、分岐流路１２が分岐している。その分岐流路１２の途上には、熱交換手段２０が設けられている。熱交換手段２０は、具体的には、原水が流れる通路（空間）２０ａを有するウォータージャケットである。通路２０ａは、浄水器１０の上面及び側面を囲んでいる。分岐流路１２を流れてきた原水は、入口部１４を介して、通路２０ａ内に流入し、この流入した原水は、浄水器１０の外面１０ａに直接接触して、浄水器１０との間で熱交換が行われる。
あるいは、熱交換手段２０を、浄水器１０の外面１０ａに接する内壁部と、外部の空気に接する外壁部との間に通路（空間）を形成した二重構造としてもよく、この場合には、通路内の原水は、浄水器１０の外面１０ａに接する内壁部を介して、浄水器１０と熱交換する。 On the way of the introduction flow path 2, the branch flow path 12 branches off from the upstream side of the opening / closing valve 36. A heat exchanging means 20 is provided in the middle of the branch flow path 12. Specifically, the heat exchange means 20 is a water jacket having a passage (space) 20a through which raw water flows. The passage 20 a surrounds the upper surface and the side surface of the water purifier 10. The raw water that has flowed through the branch channel 12 flows into the passage 20a via the inlet portion 14, and the raw water that has flowed in directly contacts the outer surface 10a of the water purifier 10 and is connected to the water purifier 10. Heat exchange takes place.
Alternatively, the heat exchanging means 20 may have a double structure in which a passage (space) is formed between the inner wall portion in contact with the outer surface 10a of the water purifier 10 and the outer wall portion in contact with the outside air. The raw water in the passage exchanges heat with the water purifier 10 via the inner wall portion that contacts the outer surface 10 a of the water purifier 10.

熱交換手段２０において、通路２０ａと、外部の空気とを隔てる外壁部は、断熱性の高い材料（例えば樹脂など）から構成することが望ましい。あるいは、断熱材を巻いたり、断熱構造にするのでもよい。また、二重構造とした場合において、浄水器１０の外面１０ａに接する内壁部は、熱伝導性の高い材料（例えば銅、ステンレスなど）から構成することが望ましい。このようにすれば、空間２０ｂ内の原水と浄水器１０との熱交換効率を高めることができる。   In the heat exchanging means 20, it is desirable that the outer wall portion that separates the passage 20a from the outside air is made of a highly heat-insulating material (for example, resin). Alternatively, a heat insulating material may be wound or a heat insulating structure may be used. Moreover, when it is set as a double structure, it is desirable to comprise the inner wall part which contact | connects the outer surface 10a of the water purifier 10 from materials with high heat conductivity (for example, copper, stainless steel, etc.). If it does in this way, the heat exchange efficiency with the raw | natural water in the space 20b and the water purifier 10 can be improved.

分岐流路１２において、熱交換手段２０への入口部１４よりも上流側には、開閉弁（電磁弁）２２が設けられている。開閉弁２２と、入口部１４との間には、熱交換手段２０側から導入流路２側への原水の逆流を防止する逆止弁２４が設けられている。また、通路２０ａからの原水の流出口部１６には、排水流路１８が接続されている。   In the branch flow path 12, an on-off valve (electromagnetic valve) 22 is provided on the upstream side of the inlet 14 to the heat exchange means 20. A check valve 24 is provided between the on-off valve 22 and the inlet 14 to prevent the backflow of raw water from the heat exchange means 20 side to the introduction flow path 2 side. A drainage flow path 18 is connected to the outlet 16 of the raw water from the passage 20a.

浄水器１０は、コネクタ５１、５２を介して着脱自在であり、交換時期に達した場合などに交換することができる。浄水器１０は、例えば、熱交換手段２０の底部に形成された開口（図示せず）を介して、熱交換手段２０に対して取り外したり、装着できる。熱交換手段２０の底部に形成した開口を介して浄水器１０の着脱を行う構成に限らず、熱交換手段２０の側面に形成した開口を介して着脱を行う構成としてもよい。   The water purifier 10 is detachable via the connectors 51 and 52, and can be replaced when the replacement time is reached. For example, the water purifier 10 can be removed from or attached to the heat exchange means 20 through an opening (not shown) formed in the bottom of the heat exchange means 20. Not only the structure which attaches and detaches the water purifier 10 through the opening formed in the bottom part of the heat exchange means 20, but it is good also as a structure which attaches and detaches through the opening formed in the side surface of the heat exchange means 20.

上述の具体例では、底部側には通路２０ａを設けていないが原水と浄水器１０とがより広い面積で接触してそれら両者の熱交換効率を高める観点からは、浄水器１０の底部と、熱交換手段２０の底部との間に、原水が流れる通路を設けて、浄水器１０を底部側からも冷却するようにしてもよい。   In the specific example described above, the passage 20a is not provided on the bottom side, but from the viewpoint of increasing the heat exchange efficiency between the raw water and the water purifier 10 in a wider area, You may make it cool the water purifier 10 also from the bottom part side by providing the channel | path through which raw | natural water flows between the bottom parts of the heat exchange means 20. FIG.

コネクタ５１に浄水器１０が接続されていない状態では、コネクタ５１に一体的に設けられた開閉弁（図示せず）が閉じられ、導入流路２からの原水の流出が防止される。コネクタ５１に浄水器１０が接続されると、上述の開閉弁が開となる。なお、浄水器１０への通水量や使用時間を検知する手段を設けて、浄水器１０の交換時期を知らせるようにしてもよい。   In a state where the water purifier 10 is not connected to the connector 51, an on-off valve (not shown) provided integrally with the connector 51 is closed, and the raw water is prevented from flowing out from the introduction flow path 2. When the water purifier 10 is connected to the connector 51, the above-described on-off valve is opened. In addition, you may make it notify the replacement | exchange time of the water purifier 10 by providing the means to detect the water flow amount to the water purifier 10, and use time.

また、本具体例に係る浄水生成装置は、浄水器１０の温度を測定する温度測定手段２５または、熱交換手段２０の通路２０ａ内の原水の温度を測定する温度測定手段２６を備える。温度測定手段２５、２６は、例えばサーミスタや熱電対を用いた温度測定手段である。なお、これら温度測定手段２５、２６は、いずれも浄水器１０の温度を測定するために用いられる。従って、温度測定手段２５と温度測定手段２６の両方を設ける必要は必ずしもなく、いずれか一方のみを設ければよい。   Moreover, the water purification apparatus according to this specific example includes a temperature measurement unit 25 that measures the temperature of the water purifier 10 or a temperature measurement unit 26 that measures the temperature of raw water in the passage 20a of the heat exchange unit 20. The temperature measuring means 25 and 26 are temperature measuring means using, for example, a thermistor or a thermocouple. These temperature measuring means 25 and 26 are both used for measuring the temperature of the water purifier 10. Therefore, it is not always necessary to provide both the temperature measuring means 25 and the temperature measuring means 26, and only one of them may be provided.

温度測定手段２５、２６を設ける位置は、特に限定されないが、温度分布にむらがある場合に、高温部分をより速やかに検知してより速やかに冷却する観点から、より高温になりやすい上部の温度を測定できる位置に設けるのが望ましい。   The position at which the temperature measuring means 25 and 26 are provided is not particularly limited, but when the temperature distribution is uneven, the temperature of the upper part that is likely to become higher from the viewpoint of more quickly detecting the high temperature portion and cooling more quickly. It is desirable to provide at a position where can be measured.

また、熱交換手段２０内の原水と、浄水器１０との接触部分の材質を熱伝導性のよいものにすれば、局所的に温度が高くなった部分の熱の拡散性を向上でき、その部分の冷却効率を高めることができる。   Moreover, if the material of the contact portion between the raw water in the heat exchange means 20 and the water purifier 10 is made of a material having good thermal conductivity, the heat diffusibility of the portion where the temperature is locally increased can be improved. The cooling efficiency of the part can be increased.

さらに、本具体例に係る浄水生成装置は、図３に表されるように、使用者の操作信号や、温度測定手段２５、２６からの温度測定値を受けて、前述の開閉弁などを制御する制御装置３０を備える。   Furthermore, as shown in FIG. 3, the water purifier according to this specific example receives the operation signal of the user and the temperature measurement value from the temperature measuring means 25 and 26, and controls the above-described on-off valve. The control device 30 is provided.

次に、図４は、本発明の実施形態に係る浄水生成装置の動作フローチャートである。
なお、以下の説明において、開閉弁３６、２２は、制御装置３０からの信号により自動的に開閉制御される。開閉弁２３は、使用者によって手動で開閉される。あるいは、開閉弁２３は、使用者による操作部材の操作を受けて、制御装置３０からの信号により開閉される。 Next, FIG. 4 is an operation flowchart of the water purification device according to the embodiment of the present invention.
In the following description, the on-off valves 36 and 22 are automatically controlled to open and close by a signal from the control device 30. The on-off valve 23 is manually opened and closed by the user. Alternatively, the open / close valve 23 is opened / closed by a signal from the control device 30 in response to an operation of the operation member by the user.

浄水器１０が、コネクタ５１、５２に接続されていない場合には、ステップＳ１にて、”Ｎｏ”となり、ステップＳ２にて、コネクタ５１に一体的に設けられた開閉弁が閉じられ、かつ開閉弁２２を閉じる。浄水器１０が、コネクタ５１、５２に接続されている場合には、ステップＳ３に進み、コネクタ５１に一体的に設けられた開閉弁が開く。これにより、浄水器１０に原水が給水される。   If the water purifier 10 is not connected to the connectors 51 and 52, “No” is obtained in step S1, and the on-off valve provided integrally with the connector 51 is closed and opened / closed in step S2. The valve 22 is closed. When the water purifier 10 is connected to the connectors 51 and 52, the process proceeds to step S <b> 3 and an on-off valve provided integrally with the connector 51 is opened. Thereby, raw water is supplied to the water purifier 10.

次に、ステップＳ４における温度測定の結果（温度測定手段２５、２６のいずれか一方の測定値のみでよい）を受け、ステップＳ５にて、その温度測定値と、設計時にあらかじめ設定された所定値との比較が行われる。ここで、「所定値」は、活性炭の吸着性能が低下する、例えば３０〜４０℃であり、より好ましくは３５℃である。   Next, in response to the temperature measurement result in step S4 (only one of the temperature measurement means 25 and 26 may be measured), in step S5, the temperature measurement value and a predetermined value set in advance at the time of design are obtained. Is compared. Here, the “predetermined value” is, for example, 30 to 40 ° C., more preferably 35 ° C., at which the activated carbon adsorption performance is reduced.

温度測定値が所定値以上であり、活性炭の吸着性能の低下の可能性を示す場合には、ステップＳ６にて、開閉弁２２を開く。これにより、原水は、分岐流路１２を介して、熱交換手段２０の通路２０ａに流入し、この流入した原水は、浄水器１０と熱交換しながら、通路２０ａ内を流れて排水流路１８から排水される。すなわち、原水を利用した、浄水器１０の水冷が開始される。   If the measured temperature value is equal to or greater than the predetermined value and indicates the possibility of a decrease in the adsorption performance of the activated carbon, the on-off valve 22 is opened in step S6. Thus, the raw water flows into the passage 20a of the heat exchanging means 20 through the branch flow path 12, and the raw water that has flowed in flows through the passage 20a while exchanging heat with the water purifier 10, thereby draining the flow path 18. Drained from. That is, water cooling of the water purifier 10 using raw water is started.

そして、次のステップＳ７にて、使用者が浄水の吐水を要求しているかどうかを判定し、使用者が吐水を要求しない場合、すなわち開閉弁２３が開かれない場合には吐水しない（ステップＳ９）。   Then, in the next step S7, it is determined whether or not the user requests water discharge, and if the user does not request water discharge, that is, if the on-off valve 23 is not opened (step S9). ).

使用者が吐水を要求し、開閉弁２３が開かれた場合には、活性炭の吸着性能が低下する温度以上にあった浄水器１０の前述した水冷が開始され始めたばかりであるということを、音や光などで使用者に警告しながら、浄水器１０を通過した水が吐水流路８を介して吐水される（ステップＳ８）。この警告を受け、使用者は浄水器１０からの吐水の使用を止めたり、それほど清浄度を必要とされない用途に使用する、あるいはしばらく経ってから浄水器１０からの吐水を使用するなどの対応をとれる。   When the user demands water discharge and the on-off valve 23 is opened, the sound water cooling of the water purifier 10 that has been at a temperature higher than the temperature at which the activated carbon adsorption performance deteriorates has just started. The water that has passed through the water purifier 10 is discharged through the water discharge passage 8 while warning the user with light or light (step S8). In response to this warning, the user can stop using the water discharged from the water purifier 10, use it for an application that does not require much cleanliness, or use the water discharged from the water purifier 10 after a while. I can take it.

ステップＳ５にて、温度測定値が所定値より小さい場合には、ステップＳ１０にて、温度測定値が所定値より小さくなってから所定時間経過したかどうかの判定が、制御装置３０にてなされる。温度測定値が所定値より小さくなってから所定時間経過していない場合には、ステップＳ６に進み開閉弁２２を開いて、前述したような浄水器１０の水冷を行う。   If the temperature measurement value is smaller than the predetermined value in step S5, the control device 30 determines whether or not a predetermined time has elapsed since the temperature measurement value became smaller than the predetermined value in step S10. . If the predetermined time has not elapsed since the temperature measurement value became smaller than the predetermined value, the process proceeds to step S6, the on-off valve 22 is opened, and the water purifier 10 is cooled as described above.

温度測定値が所定値より小さくなってから所定時間経過した場合には、ステップＳ１１にて、開閉弁２２を閉じる。これにより、熱交換手段２０の通路２０ａへの原水の流入が停止され、浄水器１０の水冷が停止される。すなわち、温度測定値が所定値より小さくなっても、ただちに開閉弁２２を閉じるのではなく、しばらく通路２０ａに通水が行われるようにし、浄水器１０の内部に収容された活性炭が確実に所定温度（吸着性能が低下する温度）より低くなるようにする。もちろん、ステップＳ１０を設定せず、ステップＳ５にて温度測定値が所定値より小さくなったら、ただちに開閉弁２２を閉じるようにしてもよい。   When a predetermined time has elapsed since the measured temperature value becomes smaller than the predetermined value, the on-off valve 22 is closed in step S11. Thereby, inflow of the raw | natural water to the channel | path 20a of the heat exchange means 20 is stopped, and the water cooling of the water purifier 10 is stopped. That is, even if the temperature measurement value becomes smaller than the predetermined value, the on-off valve 22 is not immediately closed, but water is allowed to pass through the passage 20a for a while, so that the activated carbon accommodated in the water purifier 10 is reliably predetermined. The temperature should be lower than the temperature (the temperature at which the adsorption performance decreases). Of course, step S10 may not be set, and the on-off valve 22 may be closed immediately when the temperature measurement value becomes smaller than the predetermined value in step S5.

そして、ステップＳ１２にて、使用者が浄水の吐水を要求しているかどうかを判定し、使用者が吐水を要求しない場合、すなわち開閉弁２３が開かれない場合には吐水しない（ステップＳ１４）。   Then, in step S12, it is determined whether or not the user is requesting water discharge, and if the user does not request water discharge, that is, if the on-off valve 23 is not opened, water is not discharged (step S14).

使用者が吐水を要求し、開閉弁２３が開かれた場合には、警告などをせずに、浄水器１０からの浄水がそのまま吐水される（ステップＳ１３）。先のステップＳ５及びＳ１０にて”Ｙｅｓ”となることで、活性炭が、吸着性能の低下を起こす温度より低いということになるので、使用者に警告をする必要はない。   When the user requests water discharge and the on-off valve 23 is opened, the purified water from the water purifier 10 is discharged without any warning or the like (step S13). Since it becomes “Yes” in the previous steps S5 and S10, it means that the activated carbon is lower than the temperature at which the adsorption performance is lowered, so there is no need to warn the user.

なお、ステップＳ６にて、開閉弁２２を開き、かつ開閉弁３６を閉じるようにすると、使用者の吐水要求があっても（開閉弁２３が開かれても）、浄水器１０からは吐水されない。すなわち、活性炭の吸着性能が低下した状態での吐水が禁止される。また、ステップＳ５において測定温度が所定温度以上の場合に、ステップＳ６において開閉弁２３を「閉状態」にロックする、すなわち使用者から指示があっても開閉弁２３が開かないようにすれば、開閉弁３６を設けなくても、高温時の吐水を禁止することが可能となる。
なお、高温でも浄水器１０に通水する場合は、開閉弁３６はなくてもよい。 If the on-off valve 22 is opened and the on-off valve 36 is closed in step S6, water is not discharged from the water purifier 10 even if the user requests water discharge (even if the on-off valve 23 is opened). . That is, water discharge in a state where the adsorption performance of activated carbon is lowered is prohibited. In addition, when the measured temperature is equal to or higher than the predetermined temperature in step S5, the on-off valve 23 is locked in the “closed state” in step S6, that is, the on-off valve 23 is not opened even when the user gives an instruction. Even if the on-off valve 36 is not provided, water discharge at a high temperature can be prohibited.
In addition, when passing water through the water purifier 10 even at a high temperature, the on-off valve 36 may not be provided.

また、温度測定値が所定値以上にならず、熱交換手段２０の通路２０ａに通水をしていない状態でも、一定期間ごとに開閉弁２２を開き、通路２０ａへの通水を行うようにしてもよい。このとき、開閉弁３６は開いたままでもよいし、閉じていてもよい。   Even when the temperature measurement value does not exceed the predetermined value and water is not passed through the passage 20a of the heat exchanging means 20, the on-off valve 22 is opened at regular intervals so that water is passed through the passage 20a. May be. At this time, the on-off valve 36 may remain open or may be closed.

以上述べたように、本実施形態によれば、浄水器１０が、設置環境下の温度の影響を受け、活性炭の吸着性能が低下する所定温度以上になった場合でも、熱交換手段２０を流れる原水との熱交換により冷却され、これにより、活性炭の温度を上記所定温度より低下させることができる。この結果、設置環境下の温度に左右されずに、いつでも清浄度の高い浄水を提供できる。   As described above, according to the present embodiment, the water purifier 10 is affected by the temperature in the installation environment, and flows through the heat exchanging means 20 even when the water purifier 10 reaches or exceeds a predetermined temperature at which the adsorption performance of the activated carbon decreases. It cools by heat exchange with raw | natural water, and can thereby reduce the temperature of activated carbon from the said predetermined temperature. As a result, it is possible to provide clean water with high cleanliness at any time without being influenced by the temperature in the installation environment.

また、熱交換手段２０の通路２０ａに原水が供給されない状態では、その通路２０ａは、浄水器１０と、外部とを断熱する断熱部材として機能し、高温環境下における浄水器１０の温度上昇を抑えることができる。この断熱効果を高める観点からは、通路２０ａの外壁部を、例えば樹脂などの断熱性の高い材料から構成することが望ましい。通路２０ａの外壁部を断熱性の高い材料から構成することは、原水が通路２０ａ内に供給された際に、原水の温度が外部の温度の影響で上昇することも抑制する。通路２０ａ内に供給された原水と、浄水器１０の外面１０ａとの接触部分は、それら両者間の熱交換効率を良くするために、熱伝導性の高い金属などを用いることが望ましい。   Moreover, in a state where raw water is not supplied to the passage 20a of the heat exchange means 20, the passage 20a functions as a heat insulating member that insulates the water purifier 10 from the outside, and suppresses the temperature rise of the water purifier 10 in a high temperature environment. be able to. From the viewpoint of enhancing the heat insulation effect, it is desirable that the outer wall portion of the passage 20a is made of a material having high heat insulation properties such as resin. Constructing the outer wall portion of the passage 20a from a highly heat-insulating material also prevents the temperature of the raw water from rising due to the external temperature when the raw water is supplied into the passage 20a. In order to improve the heat exchange efficiency between the raw water supplied into the passage 20a and the outer surface 10a of the water purifier 10, it is desirable to use a metal having high thermal conductivity.

表１及び図１７は、クロロホルムの平衡濃度が３０（ｐｐｂ）のときの、活性炭への、クロロホルム吸着の温度依存性を表す。
この測定に用いた活性炭は、比表面積が１５００（ｍ２／ｇ）のピッチ系繊維状活性炭である。 Table 1 and FIG. 17 show the temperature dependence of chloroform adsorption on activated carbon when the equilibrium concentration of chloroform is 30 (ppb).
The activated carbon used for this measurement is pitch-based fibrous activated carbon having a specific surface area of 1500 (m 2 / g).

Figure 2007222840
Figure 2007222840

これら結果から、温度が高くなるにつれ、活性炭へのクロロホルムの吸着量は低下していることがわかる。実用上、活性炭を、例えば３０〜４０℃より低い温度にすれば十分であり、すなわち一般的な水道水の水温と同等の温度まで冷却すれば、想定の使用温度内に入るため、前述したような原水（水道水）との熱交換による水冷で十分であり、ペルチェ効果を利用した電子冷却装置を用いる特許文献２や、冷凍機を用いる特許文献３に比べて、省電力かつ安価である。   From these results, it can be seen that the amount of chloroform adsorbed on the activated carbon decreases as the temperature increases. In practice, it is sufficient to set the activated carbon to a temperature lower than, for example, 30 to 40 ° C., that is, if it is cooled to a temperature equivalent to the water temperature of general tap water, it falls within the assumed operating temperature. Water cooling by heat exchange with natural raw water (tap water) is sufficient, and power saving and inexpensive compared to Patent Document 2 using an electronic cooling device using the Peltier effect and Patent Document 3 using a refrigerator.

また、温度測定手段からの測定温度に基づいて、所定温度以上のときだけ通路２０ａに原水が流れるようにして浄水器１０の水冷を行うので、水の使用量も節約できる。   Further, since the water purifier 10 is cooled with the raw water flowing in the passage 20a only when the temperature is higher than the predetermined temperature based on the measured temperature from the temperature measuring means, the amount of water used can be saved.

以下、本発明の他の具体例について説明する。なお、前出したものと同様の要素については、同一の符号を付して詳細な説明は省略する。   Hereinafter, other specific examples of the present invention will be described.

However, in this specific example, an open / close valve is provided in the drainage flow path 18 instead of the branch flow path 12, and an open / close valve 36 is provided in the introduction flow path 2 downstream of the branch point of the branch flow path 12. ing. In addition, when passing water through the water purifier 10 even at a high temperature, the on-off valve 36 may not be provided.

The water purifier 10 may be in a state capable of water discharge while being water-cooled.

［第５具体例］
図８は、本発明の第５具体例に係る浄水生成装置の構成を例示する模式図である。
本具体例も、図７に表される第４具体例と同様、「元止め式」の浄水生成装置である。ただし、本具体例においては、分岐流路１２に開閉弁２２を設けている。使用者が浄水を使用したい場合は、開閉弁３６を開にする。 [Fifth example]
FIG. 8 is a schematic view illustrating the configuration of the water purification device according to the fifth example of the invention.

However, in this specific example, an on-off valve 22 is provided in the branch flow path 12. When the user wants to use purified water, the on-off valve 36 is opened.

［第６具体例］
図９は、本発明の第６具体例に係る浄水生成装置の構成を例示する模式図である。
本具体例も、「元止め式」の浄水生成装置である。すなわち、使用者が浄水を使用したい場合は、開閉弁３６を開にする。そして、本具体例が、前述した図８に表される第５具体例と異なるのは、導入流路２と分岐流路１２との分岐点と、開閉弁３６との間に開閉弁２１を設け、排水流路１８に開閉弁２２を設けている点である。 [Sixth example]
FIG. 9 is a schematic view illustrating the configuration of the water purification device according to the sixth example of the invention.
This specific example is also a “prevention type” water purification apparatus. That is, when the user wants to use purified water, the on-off valve 36 is opened. This example is different from the fifth example shown in FIG. 8 described above in that the on-off valve 21 is provided between the on-off valve 36 and the branch point between the introduction passage 2 and the branch passage 12. The on / off valve 22 is provided in the drainage flow path 18.

When the measured temperature is equal to or higher than the predetermined temperature, the on-off valve 22 is opened and the raw water for water cooling flows through the passage 20a of the heat exchange means 20. At this time, the on-off valve 21 may be closed and water discharge from the water purifier 10 may be prohibited, or the on-off valve 21 may be opened to enable water discharge while the water purifier 10 is cooled with water. Good.

上記第４〜６具体例では、浄水器１０の上流側に、浄水器１０からの浄水の吐水／止水を切り替える開閉弁を設けることにより、浄水を使用しない状態においては、水道などからの一次圧が浄水器１０に負荷されない。したがって、浄水器１０の耐水圧が低くてもよく、構造を簡略化できる。   In the said 4th-6th specific example, in the state which does not use purified water by providing the on-off valve which switches the water discharge / stop water of the purified water from the water purifier 10 in the upstream of the water purifier 10, it is primary from a water supply etc. The pressure is not applied to the water purifier 10. Therefore, the water pressure resistance of the water purifier 10 may be low, and the structure can be simplified.

［第７具体例］
図１０は、本発明の第７具体例に係る浄水生成装置の構成を例示する模式図である。
本具体例は、「先止め式」の浄水生成装置である。すなわち、使用者が浄水を使用したい場合は、開閉弁２３を開く。そして、本具体例では、熱交換手段として水槽６０を用いている。浄水器１０は、水槽６０の中に収容されている。開閉弁２２が開にされて、水槽６０内に原水が給水されると、その原水に接する外面１０ａを通じて、浄水器１０と、水槽６０内原水との間で熱交換が行われる。 [Seventh example]
FIG. 10 is a schematic view illustrating the configuration of the water purification device according to the seventh example of the invention.
This example is a “first stop type” water purification device. That is, when the user wants to use purified water, the on-off valve 23 is opened. And in this example, the water tank 60 is used as a heat exchange means. The water purifier 10 is accommodated in the water tank 60. When the on-off valve 22 is opened and raw water is supplied into the water tank 60, heat exchange is performed between the water purifier 10 and the raw water in the water tank 60 through the outer surface 10a in contact with the raw water.

水槽６０の流体入口部１４と流体出口部１６は、それぞれ、コネクタ５３、５４を介して、流路１２、１８と接続されている。コネクタ５１、５２に対して浄水器１０を着脱し、かつコネクタ５３、５４に対して水槽６０を着脱することで、浄水器１０は水槽６０ごと設置箇所から取り外したり、装着される。なお、コネクタ５１、５３は、開閉弁の機能も有し、浄水器１０、水槽６０が装着されていない場合の導入流路２からの原水の流出が防止できる。   The fluid inlet portion 14 and the fluid outlet portion 16 of the water tank 60 are connected to the flow paths 12 and 18 via connectors 53 and 54, respectively. By removing the water purifier 10 from the connectors 51 and 52 and detaching the water tank 60 from the connectors 53 and 54, the water purifier 10 is removed from the installation location or attached together with the water tank 60. In addition, the connectors 51 and 53 also have a function of an on-off valve, and can prevent the raw water from flowing out from the introduction flow path 2 when the water purifier 10 and the water tank 60 are not attached.

前述した測定温度が所定温度より小さい場合には、制御装置３０の制御によって開閉弁３６は開かれ、開閉弁２２は閉じられる。測定温度が所定温度以上である場合には、開閉弁２２が開かれ、水槽６０に水冷用の原水が給水される。このとき、開閉弁３６を閉じて、浄水器１０からの吐水が禁止される状態にしてもよいし、開閉弁３６を開いて、浄水器１０を水冷しながらの吐水が可能な状態にしてもよい。なお、高温でも浄水器１０に通水する場合は、開閉弁３６はなくてもよい。また、測定温度が所定温度以上の場合に、開閉弁２３を「閉状態」にロックする、すなわち使用者から指示があっても開閉弁２３が開かないようにすれば、開閉弁３６を設けなくても、高温時の吐水を禁止することが可能となる。   When the measured temperature is lower than the predetermined temperature, the on / off valve 36 is opened and the on / off valve 22 is closed under the control of the control device 30. When the measured temperature is equal to or higher than the predetermined temperature, the on-off valve 22 is opened, and raw water for water cooling is supplied to the water tank 60. At this time, the on-off valve 36 may be closed to prohibit water discharge from the water purifier 10, or the on-off valve 36 may be opened to enable water discharge while the water purifier 10 is cooled with water. Good. In addition, when passing water through the water purifier 10 even at a high temperature, the on-off valve 36 may not be provided. Further, if the on-off valve 23 is locked in the “closed state” when the measured temperature is equal to or higher than the predetermined temperature, that is, if the on-off valve 23 is not opened even when the user gives an instruction, the on-off valve 36 is not provided. However, water discharge at high temperatures can be prohibited.

［第８具体例］
図１１は、本発明の第８具体例に係る浄水生成装置の構成を例示する模式図である。
本具体例は、「元止め式」の浄水生成装置である。そして、本具体例が、前述した図１０に表される第７具体例と異なるのは、吐水流路８に開閉弁２３を設けず、導入流路２において、分岐流路１２との分岐点よりも下流で開閉弁３６よりも上流側に開閉弁２１を設けている点である。使用者が浄水を使用したい場合は、開閉弁３６を開にする。 [Eighth Example]
FIG. 11 is a schematic view illustrating the configuration of the water purification device according to the eighth example of the invention.
This specific example is a “primary stop type” water purification apparatus. This example is different from the above-described seventh example shown in FIG. 10 in that the on / off valve 23 is not provided in the water discharge channel 8 and the branch point between the branch channel 12 and the introduction channel 2 is different. The on / off valve 21 is provided downstream of the on / off valve 36 and further on the upstream side. When the user wants to use purified water, the on-off valve 36 is opened.

前述した測定温度が所定温度より小さい場合には、制御装置３０の制御によって開閉弁２１は開かれ、開閉弁２２は閉じられる。測定温度が所定温度以上である場合には、開閉弁２２が開かれ、水槽６０に水冷用の原水が給水される。このとき、開閉弁２１を閉じて、浄水器１０からの吐水が禁止される状態にしてもよいし、開閉弁２１を開いて、浄水器１０を水冷しながらの吐水が可能な状態にしてもよい。なお、高温でも浄水器１０に通水する場合は、開閉弁２１はなくてもよい。   When the measured temperature is lower than the predetermined temperature, the on / off valve 21 is opened and the on / off valve 22 is closed under the control of the control device 30. When the measured temperature is equal to or higher than the predetermined temperature, the on-off valve 22 is opened, and raw water for water cooling is supplied to the water tank 60. At this time, the on-off valve 21 may be closed and water discharge from the water purifier 10 may be prohibited, or the on-off valve 21 may be opened to enable water discharge while the water purifier 10 is cooled with water. Good. In addition, when passing water through the water purifier 10 even at a high temperature, the on-off valve 21 may not be provided.

［第９具体例］
図１２は、本発明の第９具体例に係る浄水生成装置の構成を例示する模式図である。
本具体例も、「元止め式」の浄水生成装置である。そして、本具体例では、前述した図７に表される第４具体例の構成に加えて、加熱装置ｈ、排出流路３８、三方弁３７をさらに備えている。 [Ninth example]
FIG. 12 is a schematic view illustrating the configuration of the water purification device according to the ninth example of the invention.
This specific example is also a “prevention type” water purification apparatus. In this specific example, in addition to the configuration of the fourth specific example shown in FIG. 7 described above, a heating device h, a discharge flow path 38, and a three-way valve 37 are further provided.

加熱装置ｈは、例えば浄水器１０の底部に設けられている。排出流路３８は、浄水の吐水流路８から分岐して設けられ、吐水流路８と排出流路３８との分岐点に、三方弁３７が設けられている。   The heating apparatus h is provided in the bottom part of the water purifier 10, for example. The discharge channel 38 is branched from the water discharge channel 8 of the purified water, and a three-way valve 37 is provided at a branch point between the water discharge channel 8 and the discharge channel 38.

図１３は、本具体例に係る浄水生成装置において、浄水器１０の加熱再生モードのフローチャートである。   FIG. 13 is a flowchart of the heating regeneration mode of the water purifier 10 in the water purification device according to this example.

浄水器１０から浄水の吐出が可能な浄水モード（熱交換手段２０による冷却中も含む）（ステップＳ１０１）において、加熱再生条件を満たすかどうかが、制御装置３０によりステップＳ１０２で判定される。加熱再生条件は、浄水器１０の加熱再生が必要な条件であり、例えば、以下のような条件が挙げられる。
・所定時刻になった。
・前回の加熱再生時から所定時間が経過した。
・加熱再生モードを実行するために使用者によって操作されるスイッチ等の操作部材が操作された。
・上記スイッチ等のオンから所定時間が経過した。
・加熱再生条件のリセットから所定時間が経過した。
・浄水器の使用時間が所定時間に達した。
・浄水器への通水量が所定量に達した。 In the purified water mode (including during cooling by the heat exchange means 20) in which purified water can be discharged from the water purifier 10 (step S101), whether or not the heating regeneration condition is satisfied is determined by the control device 30 in step S102. The heating regeneration condition is a condition that requires heating regeneration of the water purifier 10, and examples thereof include the following conditions.
・ The time has come.
・ The specified time has passed since the last heating regeneration.
-An operation member such as a switch operated by the user to execute the heating regeneration mode was operated.
• A predetermined time has elapsed since the above switches were turned on.
• A predetermined time has elapsed since the resetting of the heat regeneration conditions.
・ The usage time of the water purifier has reached the specified time.
・ The amount of water passed to the water purifier has reached the specified amount.

加熱再生条件を満たさない場合は、浄水モードが続けられる。加熱再生条件を満たす場合は、ステップＳ１０３にて、浄水器１０の使用開始、または前回の加熱再生時から、浄水器１０への通水があったかどうかが判定される。この通水がない場合は、ステップＳ１０４にて加熱再生条件がリセットされ、浄水モードが続けられる。   If the heating regeneration condition is not satisfied, the water purification mode is continued. If the heating regeneration condition is satisfied, it is determined in step S103 whether or not water has been passed to the water purifier 10 from the start of use of the water purifier 10 or the previous heating regeneration. If there is no water flow, the heating regeneration condition is reset in step S104, and the water purification mode is continued.

上述の通水があった場合は、ステップＳ１０５にて、浄水の吐水中かどうかが判定される。浄水が吐水中でない場合には、加熱再生モード（ステップＳ１０６）に移行する。浄水の吐水中である場合には、加熱再生モードに移行せず、浄水の吐水の停止を待ってから加熱再生モード（ステップＳ１０６）に移行する。   When there is the above-mentioned water flow, it is determined in step S105 whether or not the water is being discharged. If the purified water is not discharged water, the process proceeds to the heating regeneration mode (step S106). When the water is being discharged, the process does not shift to the heating regeneration mode, but waits for the water discharge to stop before shifting to the heating regeneration mode (step S106).

加熱再生モードでは、制御装置３０の制御により、加熱装置（ヒーター）ｈが通電され、浄水器１０を加熱する。このとき、三方弁３５は、導入流路２と浄水器１０との間及び導入流路２と熱交換手段２０との間を遮断し、浄水器１０及び熱交換手段２０への原水の給水は停止される。また、三方弁３７は、浄水器１０と浄水の吐水流路８との間を遮断し、浄水器１０と排出流路３８との間を連通させる。   In the heating regeneration mode, the heating device (heater) h is energized under the control of the control device 30 to heat the water purifier 10. At this time, the three-way valve 35 shuts off between the introduction flow path 2 and the water purifier 10 and between the introduction flow path 2 and the heat exchange means 20, and supply of raw water to the water purifier 10 and the heat exchange means 20 is performed. Stopped. Moreover, the three-way valve 37 interrupts | blocks between the water purifier 10 and the water discharging flow path 8, and connects between the water purifier 10 and the discharge flow path 38. FIG.

加熱装置ｈによって浄水器１０が加熱されると、浄水器１０内に残留していた水が蒸気になると共に、活性炭に吸着していた有害物質や異臭味物質が脱離して、蒸気と共に排出流路３８から排出される。これにより、浄水器１０の活性炭は清浄化され、使用寿命が延びる。また、三方弁３７は、浄水器１０と浄水の吐水流路８との間を遮断し、浄水器１０と排出流路３８との間を連通させているので、活性炭から脱離した有害物質等が濃縮された水や蒸気が、浄水の吐水流路８から使用者の元に吐水されるのを防ぐことができる。   When the water purifier 10 is heated by the heating device h, the water remaining in the water purifier 10 becomes steam, and harmful substances and off-flavor substances adsorbed on the activated carbon are desorbed and discharged together with the steam. It is discharged from the path 38. Thereby, the activated carbon of the water purifier 10 is cleaned and the service life is extended. In addition, the three-way valve 37 blocks between the water purifier 10 and the water discharge flow path 8 and allows the water purifier 10 and the discharge flow path 38 to communicate with each other. It is possible to prevent water or steam in which water is concentrated from being discharged from the purified water discharge flow path 8 to the user.

次に、浄水器１０の温度を測定する温度測定手段２５の温度測定値に基づいて、ステップＳ１０７にて、浄水器１０が所定温度（例えば１２０〜１５０℃）にまで加熱されたかどうかを判定する。浄水器１０がその所定温度に達している場合には、ステップＳ１０８にて加熱再生モードが終了され、さらにステップＳ１１０にて、加熱再生モード開始から所定時間経過していると判定された場合には、浄水モードに戻る。加熱再生モードの終了から所定時間経過していない場合には、まだ浄水器１０は高温である可能性があり、その状態で浄水モードに移行してしまうと、活性炭による有害物質等の吸着作用が十分に得られない可能性があるので、加熱再生モードが終了した後、浄水器１０が冷えるのを待ってから浄水モードに戻すようにする。なお、ステップＳ１１０はなくてもよく、加熱再生モード終了直後に自動的に熱交換手段２０側に原水が流れるようにして、瞬時に浄水器１０を水冷してもよい。また、ステップＳ１１０の間に熱交換手段２０に通水して、浄水器１０を急冷するようにしてもよい。   Next, based on the temperature measurement value of the temperature measuring means 25 that measures the temperature of the water purifier 10, it is determined in step S107 whether or not the water purifier 10 has been heated to a predetermined temperature (for example, 120 to 150 ° C.). . If the water purifier 10 has reached the predetermined temperature, the heating regeneration mode is terminated in step S108, and if it is determined in step S110 that a predetermined time has elapsed from the start of the heating regeneration mode. Return to water purification mode. If the predetermined time has not elapsed since the end of the heating regeneration mode, the water purifier 10 may still be at a high temperature. If the water purifier 10 is shifted to the water purification mode in this state, the activated carbon absorbs harmful substances and the like. Since there is a possibility that it cannot be obtained sufficiently, after the heating regeneration mode ends, the water purifier 10 is allowed to cool before returning to the purified water mode. Note that step S110 may not be provided, and the water purifier 10 may be instantaneously cooled with water so that the raw water automatically flows to the heat exchanging means 20 side immediately after the end of the heating regeneration mode. Further, the water purifier 10 may be cooled rapidly by passing water through the heat exchanging means 20 during step S110.

加熱再生モード終了前のステップＳ１０７にて、浄水器１０が所定温度に達していない場合には、ステップＳ１０９にて加熱再生モード開始から所定時間経過したかどうかが判定され、加熱再生モード開始から所定時間経過した場合には、加熱再生モードを終了する（ステップＳ１０８）。これは、浄水器１０の過剰な加熱を防ぐためである。   If the water purifier 10 has not reached the predetermined temperature in step S107 before the end of the heating regeneration mode, it is determined in step S109 whether a predetermined time has elapsed from the start of the heating regeneration mode. If the time has elapsed, the heating regeneration mode is terminated (step S108). This is to prevent excessive heating of the water purifier 10.

［第１０具体例］
図１４は、本発明の第１０具体例に係る浄水生成装置の構成を例示する模式図である。本具体例も、「元止め式」の浄水生成装置である。すなわち、使用者が浄水を使用する場合には、開閉弁３６を開く。そして、本具体例では、上記第９具体例における排水・排気流路３８に対応する排出流路４２を、コネクタ５２と、浄水器１０の出口部６との間から分岐させて設けている。さらに、排出流路４２に開閉弁４１を設けている。 [Tenth example]
FIG. 14 is a schematic view illustrating the configuration of the water purification device according to the tenth example of the invention. This specific example is also a “prevention type” water purification apparatus. That is, when the user uses purified water, the on-off valve 36 is opened. In this specific example, the discharge flow path 42 corresponding to the drainage / exhaust flow path 38 in the ninth specific example is branched from the connector 52 and the outlet portion 6 of the water purifier 10. Further, an opening / closing valve 41 is provided in the discharge flow path 42.

加熱再生モード時には、制御装置３０の制御により開閉弁２３は閉じられ、開閉弁４１は開けられて、加熱装置ｈからの加熱により活性炭から脱離した有害物質等が濃縮された水や蒸気は、排出流路４２から排出される。なお、図示しないが、排出流路４２にもコネクタが設けられ、排出流路４２に対する浄水器１０の着脱を可能にしている。   In the heating regeneration mode, the on / off valve 23 is closed and the on / off valve 41 is opened under the control of the control device 30, and water or steam in which harmful substances and the like desorbed from the activated carbon by the heating from the heating device h are concentrated, It is discharged from the discharge channel 42. Although not shown, the discharge channel 42 is also provided with a connector, so that the water purifier 10 can be attached to and detached from the discharge channel 42.

また、前述の第９、１０具体例においては、熱交換手段２０への給水／止水を切り替える手段は、熱交換手段２０の上流側に設けた、いわゆる「元止め式」の構造であり、排水流路１８には開閉弁が設けられていないので、加熱再生モード時の加熱により膨張した通路２０ａ内の原水や、蒸気を排水流路１８から逃がすことができる。   Further, in the ninth and tenth specific examples described above, the means for switching between water supply and water stop to the heat exchange means 20 is a so-called “primary stop” structure provided on the upstream side of the heat exchange means 20, Since the drainage channel 18 is not provided with an on-off valve, the raw water and steam in the passage 20a expanded by heating in the heating regeneration mode can be released from the drainage channel 18.

［第１１具体例］
図１５は、本発明の第１１具体例に係る浄水生成装置の構成を例示する模式図である。本具体例は、「先止め式」の浄水生成装置である。そして、本具体例では、熱交換手段である水槽６０において、入口部１４付近の比較的低温の原水と、浄水器１０と熱交換した、出口部１６付近の比較的温度の高い原水とが混ざり合うのを規制する整流板４６を設けている。これにより、すでに浄水器１０と熱交換されて温度が上昇した原水によって、水槽６０内に給水され浄水器１０と熱交換する前の原水が温められてしまうのを防いで、交換効率を高めることができる。 [Eleventh Example]
FIG. 15 is a schematic view illustrating the configuration of the water purification device according to the eleventh example of the invention. This example is a “first stop type” water purification device. And in this specific example, in the water tank 60 which is a heat exchanging means, the relatively low temperature raw water near the inlet portion 14 and the raw water having a relatively high temperature near the outlet portion 16 which exchanges heat with the water purifier 10 are mixed. A rectifying plate 46 for restricting the fitting is provided. As a result, the raw water that has already been heat-exchanged with the water purifier 10 and increased in temperature is prevented from being heated in the aquarium 60 and heated before the water purifier 10 is heat-exchanged, thereby improving the exchange efficiency. Can do.

［第１２具体例］
図１６は、本発明の第１２具体例に係る浄水生成装置の構成を例示する模式図である。本具体例では、浄水器１０に、くぼみまたは中空部５６を設けて、水槽６０内の原水との接触面積を増大させると共に、浄水器１０を内側からも冷却するようにしている。このようにすれば、浄水器１０の冷却効率をさらに高くできる。 [Twelfth example]
FIG. 16 is a schematic view illustrating the configuration of the water purification device according to the twelfth specific example of the invention. In this specific example, the water purifier 10 is provided with a recess or a hollow portion 56 to increase the contact area with the raw water in the water tank 60 and to cool the water purifier 10 from the inside. In this way, the cooling efficiency of the water purifier 10 can be further increased.

なお、上述した各具体例は、技術的に可能な限り適宜組み合わせて実施してもよく、これらも本発明の範囲に包含される。   It should be noted that the specific examples described above may be combined as appropriate as technically possible, and these are also included in the scope of the present invention.

また、温度測定手段の温度によって、熱交換手段側に流入する原水の量を調整しても良い。例えば、夏場などの徐々に温度が上昇していき所定温度を若干越えた場合に比べて、熱の発生する調理器を浄水器の近くで利用した場合は、急激に温度が上昇することが予想されるため、そういった場合は、熱交換手段に流入する原水の水量を増加することで有害物質の吐水を抑制できると共に、浄水が吐水されない状態を瞬時に解消することができる。   Moreover, you may adjust the quantity of the raw | natural water which flows in into the heat exchange means side with the temperature of a temperature measurement means. For example, it is expected that the temperature will rise sharply when a cooker that generates heat is used near the water purifier, compared to the case where the temperature gradually rises and slightly exceeds the specified temperature, such as in summer. Therefore, in such a case, the amount of raw water flowing into the heat exchanging means can be increased to suppress the discharge of harmful substances, and the state in which the purified water is not discharged can be eliminated instantly.

また、上述したように熱の発生する調理器を浄水器の近くで利用した場合は、急激に温度が上昇してしまうことが想定される。したがって、温度測定手段で測定した温度の単位時間あたりの温度変化量を検知して、その温度変化量が所定値以上の場合には、熱交換手段側へ原水の流れを切り替えるか否かを判定している所定温度以下の場合であっても、未然にその所定温度になることを予想して熱交換手段側に原水が流れるようにしても良い。   Moreover, when the cooker which generate | occur | produces heat as mentioned above is utilized near the water purifier, it is assumed that temperature will rise rapidly. Therefore, the amount of temperature change per unit time of the temperature measured by the temperature measuring means is detected, and if the amount of temperature change is a predetermined value or more, it is determined whether or not to switch the raw water flow to the heat exchange means side. Even when the temperature is lower than the predetermined temperature, the raw water may flow to the heat exchanging means in anticipation of the predetermined temperature.
