FIG.1, FIG.2, FIG.3 is a block diagram of the electrolyzed water generating apparatus in 1st Embodiment. The electrolyzed water generating apparatus is an apparatus for electrolyzing water in an electrolytic cell to generate electrolyzed water, and the pre-filter 20 and the membrane filtration cartridge 30 (hereinafter collectively referred to as "filtering portion") are electrolyzed cells. It is equipped on the 40 inflow side. The prefilter 20 is made of activated carbon, a hollow fiber membrane or the like. The membrane filtration cartridge 30 internally comprises a reverse osmosis membrane or a nanofiltration membrane. The electrolytic cell 40 is divided into two by a diaphragm 43 into a cathode chamber provided with a cathode 41 and an anode chamber provided with an anode 42. Alkaline ionized water is produced as electrolytic water in the cathode chamber and acidic ionized water is produced in the anode chamber. Here, the electrolyzed water generating apparatus includes a bypass water passage 61 for avoiding water flow to the electrolytic cell 40 and the filtration unit, and the water passage is switched by the switching valve in accordance with the use mode. The installation location of the switching valve is (1) between the raw water inlet 10 and the pre-filter 20, (2) between the pre-filter 20 and the membrane filtration cartridge 30, (3) the membrane filtration cartridge 30, and It may be at least one of the electrolytic cells 40. A switching valve 74 is also installed in the connecting portion of the spout 50 and the bypass water channel 61.
　まず、図１を用いて、（１）原水導入口１０とプレフィルタ２０の間に切替弁７１を設置した場合について説明する。この場合、使用モードが手洗いモードのときは、図１（ａ）に示すように、切替弁７１をバイパス水路６１側に切り替える。これにより、原水導入口１０から導入した原水を吐水口５０から得ることができる。図中に縞模様で示す水路は通水がないことを意味している（以下、同様）。一方、使用モードが電解水モードのときは、図１（ｂ）に示すように、切替弁７１をプレフィルタ２０側に切り替える。これにより、原水導入口１０から導入した原水をプレフィルタ２０と膜濾過カートリッジ３０で濾過し、電解槽４０で電気分解して吐水口５０から電解水を得ることができる。 First, the case where the switching valve 71 is installed between the raw water inlet 10 and the prefilter 20 will be described with reference to FIG. In this case, when the use mode is the hand wash mode, as shown in FIG. 1A, the switching valve 71 is switched to the bypass water channel 61 side. Thereby, the raw water introduced from the raw water inlet 10 can be obtained from the water outlet 50. The waterways indicated by stripes in the figure mean that there is no water flow (the same applies hereinafter). On the other hand, when the use mode is the electrolyzed water mode, as shown in FIG. 1B, the switching valve 71 is switched to the pre-filter 20 side. As a result, the raw water introduced from the raw water inlet 10 can be filtered by the prefilter 20 and the membrane filtration cartridge 30 and electrolyzed in the electrolytic tank 40 to obtain electrolytic water from the water outlet 50.
　次に、図２を用いて、（２）プレフィルタ２０と膜濾過カートリッジ３０の間に切替弁７２を設置した場合について説明する。この場合、使用モードが浄水モードのときは、図２（ａ）に示すように、切替弁７２をバイパス水路６１側に切り替える。これにより、原水導入口１０から導入した原水をプレフィルタ２０で濾過し、吐水口５０から浄水を得ることができる。一方、使用モードが電解水モードのときは、図２（ｂ）に示すように、切替弁７２を膜濾過カートリッジ３０側に切り替える。これにより、原水導入口１０から導入した原水をプレフィルタ２０と膜濾過カートリッジ３０で濾過し、電解槽４０で電気分解して吐水口５０から電解水を得ることができる。 Next, the case where the switching valve 72 is installed between the pre-filter 20 and the membrane filtration cartridge 30 will be described with reference to FIG. In this case, when the use mode is the water purification mode, as shown in FIG. 2A, the switching valve 72 is switched to the bypass water channel 61 side. Thereby, the raw water introduced from the raw water inlet 10 can be filtered by the prefilter 20, and the purified water can be obtained from the water outlet 50. On the other hand, when the use mode is the electrolyzed water mode, as shown in FIG. 2B, the switching valve 72 is switched to the membrane filtration cartridge 30 side. As a result, the raw water introduced from the raw water inlet 10 can be filtered by the prefilter 20 and the membrane filtration cartridge 30 and electrolyzed in the electrolytic tank 40 to obtain electrolytic water from the water outlet 50.
　次に、図３を用いて、（３）膜濾過カートリッジ３０と電解槽４０の間に切替弁７３を設置した場合について説明する。この場合、使用モードが軟水モードのときは、図３（ａ）に示すように、切替弁７３をバイパス水路６１側に切り替える。これにより、原水導入口１０から導入した原水をプレフィルタ２０と膜濾過カートリッジ３０で濾過し、吐水口５０から軟水を得ることができる。一方、使用モードが電解水モードのときは、図３（ｂ）に示すように、切替弁７３を電解槽４０側に切り替える。これにより、原水導入口１０から導入した原水をプレフィルタ２０と膜濾過カートリッジ３０で濾過し、電解槽４０で電気分解して吐水口５０から電解水を得ることができる。 Next, the case where the switching valve 73 is installed between the membrane filtration cartridge 30 and the electrolytic cell 40 will be described with reference to FIG. In this case, when the use mode is the soft water mode, as shown in FIG. 3A, the switching valve 73 is switched to the bypass water channel 61 side. Thereby, the raw water introduced from the raw water inlet 10 can be filtered by the prefilter 20 and the membrane filtration cartridge 30, and soft water can be obtained from the water outlet 50. On the other hand, when the use mode is the electrolyzed water mode, as shown in FIG. 3B, the switching valve 73 is switched to the electrolytic cell 40 side. As a result, the raw water introduced from the raw water inlet 10 can be filtered by the prefilter 20 and the membrane filtration cartridge 30 and electrolyzed in the electrolytic tank 40 to obtain electrolytic water from the water outlet 50.
　以上のように、第１実施形態における電解水生成装置によれば、使用モードに応じて濾過部への通水を避けることができるので、濾過部の寿命を長期化することができる。また、使用モードに応じて電解槽４０への通水を避けることができるので、電解槽４０の寿命も長期化することができる。 As mentioned above, according to the electrolyzed water generating apparatus in 1st Embodiment, since water flow to a filtration part can be avoided according to a use mode, lifetime of a filtration part can be prolonged. Moreover, since the water flow to the electrolytic cell 40 can be avoided according to a use mode, the lifetime of the electrolytic cell 40 can also be lengthened.
　（第２実施形態）
　図５は、第２実施形態における電解水生成装置の構成図である。この電解水生成装置は、バイパス水路６１と吐水口５０の連結部から電解槽４０側への逆流を防止する逆流防止弁７５を備えている。その他の点は第１実施形態と同様である。 Second Embodiment
FIG. 5: is a block diagram of the electrolyzed water generating apparatus in 2nd Embodiment. This electrolyzed water generating device is provided with a backflow prevention valve 75 for preventing backflow from the connection portion of the bypass water channel 61 and the water discharge port 50 to the electrolytic cell 40 side. The other points are the same as in the first embodiment.
　逆流防止弁７５としては、例えばバネ式のものを採用することができる。順方向通水時は、図６（ａ）に示すように、バネ７６が縮むことで水路が開き通水する。一方、逆方向通水時は、図６（ｂ）に示すように、水圧で水路が閉鎖され、水が流れない。これにより、手洗いモード等の場合においてバイパス水路６１を経由している水が電解槽４０側へ流出することを防止することができ、吐水口５０とバイパス水路６１の連結部分に切替弁７４を設けなくて済む。 As the non-return valve 75, for example, a spring type can be employed. At the time of forward water flow, as shown in FIG. 6A, the water channel opens and water flows by the spring 76 being contracted. On the other hand, when water flows in the reverse direction, as shown in FIG. 6 (b), the water channel is closed by water pressure and water does not flow. Thereby, it is possible to prevent the water passing through the bypass water channel 61 from flowing out to the electrolytic bath 40 side in the case of the hand washing mode etc., and the switching valve 74 is provided at the connection portion of the water outlet 50 and the bypass water channel 61. It is not necessary.
　以上のように、第２実施形態における電解水生成装置によれば、バイパス水路６１と吐水口５０の連結部から電解槽４０側への逆流を防止する逆流防止弁７５を備えているので、吐水口５０とバイパス水路６１の連結部分に切替弁７４を設けなくて済み、切替操作も不要となる。 As described above, according to the electrolyzed water generating device in the second embodiment, the backflow prevention valve 75 for preventing the backflow from the connection portion between the bypass water passage 61 and the water discharge port 50 to the electrolytic cell 40 side is provided. It is not necessary to provide the switching valve 74 in the connection part of the water port 50 and the bypass water channel 61, and the switching operation is also unnecessary.
　（第３実施形態）
　図７、図８、図９、図１０は、第３実施形態における電解水生成装置の構成図である。この電解水生成装置は、使用モードを選択する選択部８１と、選択部８１により選択された使用モードに基づき切替弁を切り替える制御部８２とを備えている。その他の点は第１実施形態と同様である。 Third Embodiment
7, 8, 9 and 10 are configuration diagrams of the electrolyzed water generating device in the third embodiment. The electrolyzed water generating apparatus includes a selection unit 81 which selects a use mode, and a control unit 82 which switches the switching valve based on the use mode selected by the selection unit 81. The other points are the same as in the first embodiment.
　選択部８１は、使用モードを選択するためのボタン群や表示部等である。図７では「手洗いモード」が、図８では「浄水モード」が、図９では「軟水モード」が、図１０では「電解水モード」がそれぞれ選択されている。制御部８２は、ＣＰＵとプログラムＲＯＭと作業用ＲＡＭと入出力インタフェースとを備えたマイクロプロセッサ等である。制御部８２の主要な制御は、ＣＰＵがプログラムＲＯＭに格納されたプログラムを実行することにより実現される。 The selection unit 81 is a button group or a display unit for selecting a use mode. The "hand wash mode" is selected in FIG. 7, the "clean water mode" in FIG. 8, the "soft water mode" in FIG. 9, and the "electrolyzed water mode" in FIG. The control unit 82 is a microprocessor or the like provided with a CPU, a program ROM, a work RAM, and an input / output interface. The main control of the control unit 82 is realized by the CPU executing a program stored in the program ROM.
　図１１は、制御部８２の制御内容を説明するための図である。この図に示すように、制御部８２は、「手洗いモード」が選択された場合、切替弁７１をバイパス水路６１側に、切替弁７２を膜濾過カートリッジ３０側に、切替弁７３を電解槽４０側に、切替弁７４をバイパス水路６１側に切り替える。また、「浄水モード」が選択された場合、切替弁７１をプレフィルタ２０側に、切替弁７２をバイパス水路６１側に、切替弁７３を電解槽４０側に、切替弁７４をバイパス水路６１側に切り替える。また、「軟水モード」が選択された場合、切替弁７１をプレフィルタ２０側に、切替弁７２を膜濾過カートリッジ３０側に、切替弁７３をバイパス水路６１側に、切替弁７４をバイパス水路６１側に切り替える。また、「電解水モード」が選択された場合、切替弁７１をプレフィルタ２０側に、切替弁７２を膜濾過カートリッジ３０側に、切替弁７３を電解槽４０側に、切替弁７４を電解槽４０側に切り替える。 FIG. 11 is a diagram for explaining control contents of the control unit 82. As shown in FIG. As shown in this figure, when the "hand wash mode" is selected, the control unit 82 sets the switching valve 71 to the bypass channel 61 side, the switching valve 72 to the membrane filtration cartridge 30 side, and the switching valve 73 to the electrolytic bath 40. On the other hand, the switching valve 74 is switched to the bypass water channel 61 side. When the “clean water mode” is selected, the switching valve 71 is on the prefilter 20 side, the switching valve 72 is on the bypass water channel 61, the switching valve 73 is on the electrolytic tank 40, and the switching valve 74 is on the bypass water channel 61. Switch to When the soft water mode is selected, the switching valve 71 is on the prefilter 20 side, the switching valve 72 on the membrane filtration cartridge 30 side, the switching valve 73 on the bypass water channel 61, and the switching valve 74 on the bypass water channel 61. Switch to the side. When the “electrolyzed water mode” is selected, the switching valve 71 is on the prefilter 20 side, the switching valve 72 on the membrane filtration cartridge 30 side, the switching valve 73 on the electrolytic cell 40 side, and the switching valve 74 on the electrolytic cell Switch to the 40 side.
　このように、水の流れない箇所に設置されている切替弁については、バイパス水路６１ではない向きに切り替えるようにしているので水の逆流を防止することができる。例えば、「手洗いモード」では、切替弁７２及び７３が設置されている箇所は水が流れないが、切替弁７２は膜濾過カートリッジ３０側に、切替弁７３は電解槽４０側に切り替えるようになっている。 As described above, since the switching valve installed at the place where the water does not flow is switched to the direction other than the bypass water passage 61, the backflow of water can be prevented. For example, in the "hand wash mode", water does not flow through the locations where the switching valves 72 and 73 are installed, but the switching valve 72 is switched to the membrane filtration cartridge 30 side and the switching valve 73 is switched to the electrolytic cell 40 side. ing.
　以上のように、第３実施形態における電解水生成装置によれば、選択部８１により選択された使用モードに基づき制御部８２が切替弁を切り替えるので、切替弁を適切な向きへ自動的に切替えることができる。また、水の流れない箇所に設置されている切替弁については、バイパス水路６１ではない向きに切り替えるようにしているので水の逆流を防止することができる。 As described above, according to the electrolyzed water generating apparatus in the third embodiment, the control unit 82 switches the switching valve based on the use mode selected by the selecting unit 81, so that the switching valve is automatically switched to an appropriate direction. be able to. In addition, since the switching valve installed at the place where the water does not flow is switched to a direction other than the bypass water passage 61, it is possible to prevent the backflow of water.

　図１５は、瞬時流量を検出する流量検出部９０を１個設けた場合における交換時期判断手順を示すフローチャートである。流量検出部９０が１個の場合は、使用モードに対して交換時期を判断する濾材を決め、検出値と交換時期判断値との比較により交換時期を判断する。具体的には、浄水モードのときはプレフィルタ２０の交換時期を判断し、軟水モードと電解水モードのときは膜濾過カートリッジ３０の交換時期を判断する（図１６参照）。 FIG. 15 is a flowchart showing the replacement timing determination procedure in the case where one flow rate detector 90 for detecting the instantaneous flow rate is provided. When the flow rate detection unit 90 is one, a filter medium for determining the replacement time is determined for the use mode, and the replacement time is determined by comparing the detected value with the replacement time determination value. Specifically, when in the water purification mode, the replacement time of the prefilter 20 is determined, and when in the soft water mode and the electrolyzed water mode, the replacement time of the membrane filtration cartridge 30 is determined (see FIG. 16).
　まず、通水が開始されると使用モードを確認し、手洗いモードの場合は交換時期を判断しない（ステップＳ１→Ｓ２→Ｓ２１→Ｓ２２）。一方、浄水モードの場合は流量検出部９０の検出値Ｑ２とプレフィルタ２０の交換時期判断値Ｂとを比較する（ステップＳ３→Ｓ１３→Ｓ１４→Ｓ１５）。そして、検出値Ｑ２が交換時期判断値Ｂよりも大きいときは交換時期ではないと判断し（ステップＳ１５→Ｓ１９→Ｓ２０）、逆に、検出値Ｑ２が交換時期判断値Ｂよりも小さいときはプレフィルタ２０の交換時期であると判断して、その旨を交換時期表示部８４に表示させる（ステップＳ１５→Ｓ１６→Ｓ１７→Ｓ１８）。さらに、軟水モードと電解水モードの場合は流量検出部９０の検出値Ｑ１と膜濾過カートリッジ３０の交換時期判断値Ａとを比較する（ステップＳ４→Ｓ５→Ｓ６→Ｓ７）。そして、検出値Ｑ１が交換時期判断値Ａよりも大きいときは交換時期ではないと判断し（ステップＳ７→Ｓ１１→Ｓ１２）、逆に、検出値Ｑ１が交換時期判断値Ａよりも小さいときは膜濾過カートリッジ３０の交換時期であると判断して、その旨を交換時期表示部８４に表示させる（ステップＳ７→Ｓ８→Ｓ９→Ｓ１０）。 First, when the water flow is started, the usage mode is confirmed, and in the case of the hand washing mode, the replacement time is not determined (step S1 → S2 → S21 → S22). On the other hand, in the case of the water purification mode, the detection value Q2 of the flow rate detection unit 90 is compared with the replacement timing judgment value B of the prefilter 20 (steps S3 → S13 → S14 → S15). Then, when the detected value Q2 is larger than the replacement time determination value B, it is determined that it is not replacement time (step S15 → S19 → S20), conversely, when the detected value Q2 is smaller than the replacement time determination value B It is determined that it is time to replace the filter 20, and a message to that effect is displayed on the replacement time display section 84 (steps S15 → S16 → S17 → S18). Furthermore, in the case of the soft water mode and the electrolyzed water mode, the detection value Q1 of the flow rate detection unit 90 is compared with the replacement timing determination value A of the membrane filtration cartridge 30 (steps S4 → S5 → S6 → S7). Then, when the detected value Q1 is larger than the replacement time determination value A, it is determined that it is not replacement time (steps S7 → S11 → S12), conversely, when the detected value Q1 is smaller than the replacement time determination value A It is determined that it is time to replace the filtration cartridge 30, and a message to that effect is displayed on the replacement time display section 84 (steps S7 → S8 → S9 → S10).
　なお、交換時期判断値Ａ、Ｂの決め方は特に限定されるものではない。例えば、浄水モードのときに比べて軟水モードや電解水モードにしたときに流量が低下すれば、膜濾過カートリッジ３０の目詰まりが発生していると考えることができる。そこで、膜濾過カートリッジ３０の交換時期判断値Ａは、浄水モードにおける流量検出部９０の検出値Ｑ２と軟水モードや電解水モードにおける流量検出部９０の検出値Ｑ１との差分に基づいて決めてもよい。 Note that how to determine the replacement time determination values A and B is not particularly limited. For example, if the flow rate is lowered when the soft water mode or the electrolytic water mode is selected as compared with the water purification mode, it can be considered that the membrane filtration cartridge 30 is clogged. Therefore, even if the replacement timing determination value A of the membrane filtration cartridge 30 is determined based on the difference between the detection value Q2 of the flow rate detection unit 90 in the clean water mode and the detection value Q1 of the flow rate detection unit 90 in the soft water mode or the electrolyzed water mode. Good.
　図１７は、積算流量を検出する流量検出部９０を１個設けた場合における交換時期判断手順を示すフローチャートである。この場合、浄水モードではプレフィルタ２０の積算流量Ｌ２を検出することになる（ステップＳ４４）。そして、積算流量Ｌ２がプレフィルタ２０の交換時期判断値Ｂよりも小さいときは交換時期ではないと判断し（ステップＳ４５→Ｓ４９）、逆に、積算流量Ｌ２が交換時期判断値Ｂよりも大きいときはプレフィルタ２０の交換時期であると判断する（ステップＳ４５→Ｓ４６）。一方、軟水モードと電解水モードではプレフィルタ２０及び膜濾過カートリッジ３０の積算流量Ｌ１を検出することになる（ステップＳ３６）。そして、積算流量Ｌ１が膜濾過カートリッジ３０の交換時期判断値Ａよりも小さいときは交換時期ではないと判断し（ステップＳ３７→Ｓ４１）、逆に、積算流量Ｌ１が交換時期判断値Ａよりも大きいときは膜濾過カートリッジ３０の交換時期であると判断する（ステップＳ３７→Ｓ３８）。その他の点は瞬時流量を検出する場合と同様である。 FIG. 17 is a flowchart showing the replacement time determination procedure in the case where one flow rate detection unit 90 for detecting the integrated flow rate is provided. In this case, the integrated flow rate L2 of the prefilter 20 is detected in the water purification mode (step S44). Then, when integrated flow rate L2 is smaller than replacement time judgment value B of prefilter 20, it is judged that it is not replacement time (step S45 → S49), conversely, when integrated flow rate L2 is larger than replacement time judgment value B It is determined that it is time to replace the prefilter 20 (steps S45 to S46). On the other hand, in the soft water mode and the electrolyzed water mode, the integrated flow rate L1 of the prefilter 20 and the membrane filtration cartridge 30 is detected (step S36). Then, when the integrated flow rate L1 is smaller than the replacement time determination value A of the membrane filtration cartridge 30, it is determined that it is not the replacement time (step S37 → S41), conversely, the integrated flow rate L1 is larger than the replacement time determination value A It is determined that it is time to replace the membrane filtration cartridge 30 (step S37 → S38). The other points are the same as in the case of detecting the instantaneous flow rate.
　図１８Ａ及び図１８Ｂは、積算流量を検出する流量検出部９０を２個設けた場合における交換時期判断手順を示すフローチャートである。流量検出部９０が複数個の場合は、各々の流量検出部９０に対して交換時期を判断する濾材を決め、それぞれの検出値と交換時期判断値との比較により交換時期を判断する。以下、プレフィルタ２０の後段と膜濾過カートリッジ３０の後段の２箇所に流量検出部９０を設けた場合を想定して説明する（図１４参照）。 FIG. 18A and FIG. 18B are flowcharts showing a replacement timing determination procedure in the case where two flow rate detection units 90 for detecting the integrated flow rate are provided. If there are a plurality of flow rate detection units 90, filter media for determining the replacement time are determined for each flow rate detection unit 90, and the replacement time is determined by comparing each detected value with the replacement time determination value. The following description will be given on the assumption that the flow rate detection unit 90 is provided at two places, the rear stage of the prefilter 20 and the rear stage of the membrane filtration cartridge 30 (see FIG. 14).
　浄水モードの場合は、膜濾過カートリッジ３０の交換時期は判断せず、流量検出部９１の積算流量Ｌ１とプレフィルタ２０の交換時期判断値Ａとを比較する（ステップＳ６３→Ｓ７８→Ｓ７９→Ｓ８０）。そして、積算流量Ｌ１が交換時期判断値Ａよりも小さいときは交換時期ではないと判断し（ステップＳ８０→Ｓ８４）、逆に、積算流量Ｌ１が交換時期判断値Ａよりも大きいときはプレフィルタ２０の交換時期であると判断して、その旨を交換時期表示部８４に表示させる（ステップＳ８０→Ｓ８１→Ｓ８２）。 In the case of the water purification mode, the integrated flow rate L1 of the flow rate detection unit 91 is compared with the replacement time judgment value A of the prefilter 20 without judging the replacement time of the membrane filtration cartridge 30 (steps S63 → S78 → S79 → S80) . Then, when integrated flow rate L1 is smaller than replacement time judgment value A, it is judged that it is not replacement time (step S80 → S84), conversely, when integrated flow rate L1 is larger than replacement time judgment value A, pre-filter 20 It is judged that it is the replacement time of, and that effect is displayed on the replacement time display section 84 (steps S80 → S81 → S82).
　一方、軟水モードと電解水モードの場合は、浄水モードの場合と同様の手順でプレフィルタ２０の交換時期を判断する（ステップＳ６４→Ｓ６５→Ｓ６６→Ｓ６７）。次いで、流量検出部９２の積算流量Ｌ２と膜濾過カートリッジ３０の交換時期判断値Ｂとを比較する（ステップＳ６９→Ｓ７０）。そして、積算流量Ｌ２が交換時期判断値Ｂよりも小さいときは交換時期ではないと判断し（ステップＳ７０→Ｓ７４）、逆に、積算流量Ｌ２が交換時期判断値Ｂよりも大きいときは膜濾過カートリッジ３０の交換時期であると判断して、その旨を交換時期表示部８４に表示させる（ステップＳ７０→Ｓ７１→Ｓ７２）。 On the other hand, in the case of the soft water mode and the electrolyzed water mode, the replacement time of the pre-filter 20 is determined in the same procedure as in the case of the water purification mode (steps S64 → S65 → S66 → S67). Next, the integrated flow rate L2 of the flow rate detection unit 92 is compared with the replacement time judgment value B of the membrane filtration cartridge 30 (step S69 → S70). Then, when integrated flow rate L2 is smaller than replacement time judgment value B, it is judged that it is not replacement time (step S70 → S74), conversely, when integrated flow rate L2 is larger than replacement time judgment value B, membrane filtration cartridge It is determined that it is time to replace the T.30, and a message to that effect is displayed on the replacement time display section 84 (steps S70 → S71 → S72).
　以上のように、第４実施形態における電解水生成装置によれば、流量に基づき濾材の交換時期を判断してその判断結果を表示するようにしているので、適切なタイミングで濾材の交換時期を自動的に使用者へ知らせることができる。 As described above, according to the electrolyzed water generating apparatus of the fourth embodiment, the filter medium replacement time is determined based on the flow rate and the determination result is displayed. Therefore, the filter medium replacement time can be appropriately determined. It can notify the user automatically.
　（第５実施形態）
　図１９は、第５実施形態における電解水生成装置の構成図である。この電解水生成装置は、初期通水時において流量検出部９０により検出された流量を記憶する初期値記憶部８５を備えている。交換時期判断部８３は、初期値記憶部８５に記憶された流量と流量検出部９０により検出された流量とを比較して交換時期を判断する。その他の点は第４実施形態と同様である。 Fifth Embodiment
FIG. 19 is a block diagram of the electrolyzed water generating apparatus in 5th Embodiment. The electrolyzed water generating device includes an initial value storage unit 85 that stores the flow rate detected by the flow rate detection unit 90 at the time of initial water flow. The replacement time determination unit 83 compares the flow rate stored in the initial value storage unit 85 with the flow rate detected by the flow rate detection unit 90 to determine the replacement time. The other points are the same as in the fourth embodiment.
　初期値記憶部８５は、各使用モードで初期通水時において流量検出部９０により検出された流量（以下、「初期値」という。）を記憶する。初期通水は、一定の条件で行う必要があるため、使用者が任意に操作できるバルブではなく電磁弁の開閉等により行う。交換時期判断部８３が交換時期判断値（例：流量が半分になったとき）をあらかじめ保持している点は第４実施形態と同様である。初期通水後は通常使用を行う。 The initial value storage unit 85 stores the flow rate (hereinafter referred to as "initial value") detected by the flow rate detection unit 90 at the time of initial water flow in each use mode. Since it is necessary to carry out the initial water flow under certain conditions, it is carried out by opening and closing the solenoid valve instead of the valve which the user can operate arbitrarily. It is the same as the fourth embodiment in that the replacement timing determination unit 83 holds in advance the replacement timing determination value (for example, when the flow rate is halved). After initial water flow, use normally.
　図２０Ａ及び図２０Ｂは、瞬時流量を検出する流量検出部９０を２個設けた場合における交換時期判断手順を示すフローチャートである。以下、プレフィルタ２０の後段と膜濾過カートリッジ３０の後段の２箇所に流量検出部９０を設けた場合を想定して説明する（図１９参照）。 FIGS. 20A and 20B are flowcharts showing a replacement timing determination procedure in the case where two flow rate detection units 90 for detecting an instantaneous flow rate are provided. The following description will be given on the assumption that the flow rate detection units 90 are provided at two positions, the rear stage of the prefilter 20 and the rear stage of the membrane filtration cartridge 30 (see FIG. 19).
　浄水モードの場合において、初期値記憶部８５に初期値Ｓ１が記憶されているときは、流量検出部９１の検出値Ｑ１とプレフィルタ２０の交換時期判断値Ａとを比較する（ステップＳ９３→Ｓ１０６→Ｓ１０７→Ｓ１０８）。そして、検出値Ｑ１が交換時期判断値Ａよりも大きいときは交換時期ではないと判断し（ステップＳ１０８→Ｓ１１２）、逆に、検出値Ｑ１が交換時期判断値Ａよりも小さいときはプレフィルタ２０の交換時期であると判断して、その旨を交換時期表示部８４に表示させる（ステップＳ１０８→Ｓ１０９→Ｓ１１０）。なお、初期値記憶部８５に初期値Ｓ１が記憶されていないときは、検出値Ｑ１を初期値Ｓ１として初期値記憶部８５に記憶しておく（ステップＳ１０７→Ｓ１１４）。また、交換時期判断値Ａを例えばＡ＝Ｓ１÷２により算出して保持しておく（ステップＳ１１５）。 In the case of the water purification mode, when the initial value S1 is stored in the initial value storage unit 85, the detection value Q1 of the flow rate detection unit 91 is compared with the replacement timing determination value A of the prefilter 20 (step S93 → S106) → S107 → S108). Then, when the detected value Q1 is larger than the replacement time determination value A, it is determined that it is not replacement time (step S108 → S112), conversely, when the detected value Q1 is smaller than the replacement time determination value A, the prefilter 20 is selected. It is judged that it is the replacement time of and the effect is displayed on the replacement time display section 84 (steps S108 → S109 → S110). When the initial value S1 is not stored in the initial value storage unit 85, the detection value Q1 is stored in the initial value storage unit 85 as the initial value S1 (step S107 → S114). Further, the replacement time determination value A is calculated and held, for example, by A = S1 / 2 (step S115).
　一方、軟水モードと電解水モードの場合において、初期値記憶部８５に初期値Ｓ２が記憶されているときは、流量検出部９２の検出値Ｑ２と膜濾過カートリッジ３０の交換時期判断値Ｂとを比較する（ステップＳ９３→Ｓ９４→Ｓ９５→Ｓ９６）。そして、検出値Ｑ２が交換時期判断値Ｂよりも大きいときは交換時期ではないと判断し（ステップＳ９６→Ｓ１００）、逆に、検出値Ｑ２が交換時期判断値Ｂよりも小さいときは膜濾過カートリッジ３０の交換時期であると判断して、その旨を交換時期表示部８４に表示させる（ステップＳ９６→Ｓ９７→Ｓ９８）。なお、初期値記憶部８５に初期値Ｓ２が記憶されていないときは、検出値Ｑ２を初期値Ｓ２として初期値記憶部８５に記憶しておく（ステップＳ１０２）。また、交換時期判断値Ｂを例えばＢ＝Ｓ２÷２により算出して保持しておく（ステップＳ１０３）。 On the other hand, when the initial value S2 is stored in the initial value storage unit 85 in the soft water mode and the electrolyzed water mode, the detection value Q2 of the flow rate detection unit 92 and the replacement timing determination value B of the membrane filtration cartridge 30 The comparison is made (steps S93 → S94 → S95 → S96). Then, when the detected value Q2 is larger than the replacement time determination value B, it is determined that it is not replacement time (step S96 → S100), conversely, when the detected value Q2 is smaller than the replacement time determination value B, the membrane filtration cartridge It is determined that it is time to replace the T.30, and a message to that effect is displayed on the replacement time display section 84 (steps S96 → S97 → S98). When the initial value S2 is not stored in the initial value storage unit 85, the detection value Q2 is stored in the initial value storage unit 85 as the initial value S2 (step S102). Further, the replacement time judgment value B is calculated and held, for example, by B = S2 / 2 (step S103).
　以上のように、第５実施形態における電解水生成装置によれば、初期通水時において検出された流量に基づき濾材の交換時期を判断してその判断結果を表示するようにしているので、使用環境（水圧等）の影響も考慮して交換時期を判断することができる。 As described above, according to the electrolyzed water generating apparatus of the fifth embodiment, the filter medium replacement time is determined based on the flow rate detected at the time of initial water passage, and the determination result is displayed. The timing of replacement can be determined in consideration of the influence of the environment (water pressure etc.).
　なお、ここでは、初期値が自動的に算出されて初期値記憶部８５に記憶されることとしているが、初期値の記憶方法はこれに限定されるものではない。例えば、初期値を設定するためのモードを設け、この初期値設定モードにおいて使用者が設定した値を初期値記憶部８５に記憶するようにしてもよい。 Here, although the initial value is automatically calculated and stored in the initial value storage unit 85, the storage method of the initial value is not limited to this. For example, a mode for setting an initial value may be provided, and the value set by the user in this initial value setting mode may be stored in the initial value storage unit 85.
　なお、以上では好適な実施形態について説明したが、本発明は前記実施形態に限定されず、種々の変形が可能である。例えば、一体型プレフィルタを例示したが、プレフィルタを複数設けた場合は、それに応じて切替弁やバイパス水路６１を複数設けることもできる。 Although the preferred embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications are possible. For example, although the integrated prefilter has been illustrated, when a plurality of prefilters are provided, a plurality of switching valves and bypass channels 61 can be provided accordingly.
