Description

【0001】
【発明の属する技術分野】
本発明は、上水道などの原水を電気分解して、飲用あるいは医療用として利用するアルカリイオン水、または、化粧水や殺菌洗浄水用等として利用する酸性イオン水を製造するアルカリイオン整水器に関するものである。
【0002】
【従来の技術】
近年連続電解方式のイオン水生成器として、アルカリイオン整水器が普及している。このアルカリイオン整水器は、電解槽内で水道水等を電気分解して、陽極側に酸性イオン水を生成し、陰極側にアルカリイオン水を生成するものである。
【0003】
以下、従来の連続電解方式のアルカリイオン整水器について説明する。
図4は従来のアルカリイオン整水器の概略構造図、図5は図4に示すアルカリイオン整水器の制御ブロック図、図6は同じく概略制御フロー図である。
【0004】
図4を参照して、1は水道水等の原水管、2は水栓、3は水栓2を介して原水管1と接続されたアルカリイオン整水器、4は浄水部で、浄水部4内部には原水中の残留塩素を吸着する活性炭及び一般細菌や不純物を取り除く中空糸膜などを備えている。5は通水を確認し後述の制御手段に制御指示する流量センサ、6はグリセロリン酸カルシウムや乳酸カルシウムなどのカルシウムイオンを原水中に付与し、導電率を高めるカルシウム供給部、7は通水中は水圧で閉じ止水中は開く止水弁(メカ弁)である。8は流量センサ5及びカルシウム供給部6を経由してきた水を電気分解する電解槽、9は電解槽を2分し電極室を形成する隔膜、10,11は隔膜9で2分して形成された各電極室に配置された電極板である。
【0005】
12は電極板11側の水を通水する通水管、13は電極板10側の水を吐水する吐水管、14は通水管12にイオン水が流れてきたとき、後述する酸性水管に酸性イオン水を流すための電磁弁(酸性水用)、15は通水管12に流れてきた酸性イオン水を吐水する酸性水専用吐水管、16は通水管12に流れてきた不要な水や電解槽内の滞留水や、電極板洗浄のときのCa,Mgなどからなるスケールが溶解した洗浄水を排水するための電磁弁(排水用)、17は通水管12を介して電極板11側の不要な水、電解槽の滞留水や洗浄水を排出する排水管である。また、18は電源投入用プラグ、19は電源投入用プラグ18から交流電源を直流電源に変える電源部、20はアルカリイオン整水器3の動作を制御する制御手段、21はアルカリイオン整水器の操作状態を表示する操作表示部である。
【0006】
次に図5に示すブロック図に基づいて、上記したアルカリ整水器3の制御手段20の詳細について説明する。22は制御手段20に設けられたMPU(マイクロ・プロセッサ・ユニット)で後述する各制御部に動作指示を行う。23は流量センサ5の信号をMPU22に伝達する流量検知部、24は操作表示部21の操作内容をMPU22に伝達し、MPU22の指示に従って操作表示部21の表示を行う操作表示制御部、25はMPU22の指示に従って電極板10,11の極性及び電解の強さを制御する電解槽制御部、26はMPU22の指示に従って、電磁弁14(酸性水用)及び電磁弁16(排水用)を制御し、水の通水経路を切り替える電磁弁制御部、27は電解槽制御部25及び電磁弁制御部26の制御時間を管理するMPU22内にあるタイマーである。
【0007】
次いで上記構成のアルカリイオン整水器3について、図4、図5及び図6の概略制御フローに基づいてその動作を説明する。
【0008】
利用者が操作表示部21のアルカリイオン水の生成モードを設定する(STEP1)と、利用者の設定内容及びアルカリイオン整水器3の現在の動作状態が操作表示部21に表示される(STEP2)。次に利用者が水栓2を開くことにより、水栓2から通水された原水から、浄水部4で原水中の残留塩素の臭いや一般細菌などの不純物が取り除かれ、その下流域にある流量センサ5を通過する。流量検知部23では、通水の有無を検知し、通水検知ありと通水検知なしに振り分けられる(STEP3)。
【0009】
通水検知ありの場合、利用者が設定した生成モードに従って制御内容が振り分けられる(STEP4)。使用者がSTEP1でアルカリイオン水の生成モードに設定した場合、電磁弁16(排水用)を閉じ、電磁弁14(酸性水用)を開く(STEP5、STEP6)。さらに、流量センサ5を通過した水はカルシウム供給部6を経て電解槽8に通水される。
【0010】
ここで止水弁7(メカ弁)は、通水されたときの水圧により自動的に閉じた状態になる。電解槽8に通水された水は、電解槽制御部25により電極板10,11の極性と電解の強さを制御し電解を開始する(STEP7)。電解槽8で生成されたアルカリイオン水は吐水管13を経て外部に吐水される。一方、電解槽8で生成された酸性イオン水は、通水管12、電磁弁14(酸性水用)、酸性水専用吐水管15を経て排水される。
【0011】
利用者がSTEP1で酸性水の生成モードに設定した場合には、電磁弁14(酸性水用)を閉じ、電磁弁16(排水用)を開く(STEP8、STEP9)。電解槽8に通水された水は、電解槽制御部25により電極板10,11の極性と電解の強さを制御し電解を開始する(STEP10)。電解槽8で生成された酸性イオン水は吐水管13を経て吐水される。一方、電解槽8で生成されたアルカリイオン水は電磁弁14(酸性水用)がが閉じているため、通水管12、電磁弁16(排水用)を経て吐水される。
【0012】
また、利用者がSTEP1で浄水モードに設定した場合は、電磁弁16(排水用)と電磁弁14(酸性水用)を閉じる(STEP11、STEP12)。電解槽8に通水された水は、電解槽制御部25により電解を停止するため(STEP13)そのまま吐水管13を経て吐水される。一方、電磁弁14(酸性水用)が閉じているため通水管12の水は外部に放出されない。
【0013】
ここで、利用者が水栓2を閉めて原水通水を停止した場合、流量センサ5の信号により流量検知部23は通水なしと判断する(STEP3)。次に電解槽8の洗浄の条件を満たし洗浄要求があるかどうかを判断する(STEP14)。洗浄要求がない場合、電磁弁14(酸性水用)、電磁弁16(排水用)を共に閉じ(STEP11、STEP12)、電解槽8の電解は停止状態になる(STEP13)。
【0014】
またステップ14で洗浄要求がある場合、次に電解槽8の水の排除要求があるかどうか判定する(STEP15)。排水要求が無い場合、電磁弁14(酸性水用)、電磁弁16(排水用)をともに閉じ(STEP16、STEP17)、電解槽8は電解槽制御部25により洗浄のための電解を開始する(STEP18)。洗浄のための電解時間はタイマー27で管理し、洗浄時間が終了すると排水要求をする(STEP19)。一方、洗浄後排水要求がある場合、STEP15で排水要求ありと判定され、電磁弁16(排水用)を開く(STEP20)。排水時間はタイマー27で管理し、排水が完了した時点で、洗浄及び排水要求をクリアする(STEP21)。また排水中は電解槽8の電解は停止状態とするためにSTEP13を通過させる。
【0015】
【発明が解決しようとする課題】
このように従来のアルカリイオン整水器では、利用者が水栓2を閉めた後洗浄要求がない場合、流量センサ5の信号によって直ぐに電磁弁14,16が共に閉じられるため、吐水管13及び酸性専用吐水管15内に水が残留し、この残留水が滴り落ち利用者に不快感を与えるものであった。
【0016】
そこで本発明は、使用後に吐水管及び酸性専用吐水管の出口から水が滴らないアルカリイオン整水器を提供することを目的とする。
【0017】
【課題を解決するための手段】
上記課題を解決するために、本発明のアルカリイオン整水器は、流量センサで止水されたことを検知すると、一定時間吐水管内の水を強制排水する電磁弁の制御部を備えたことを特徴とする。
【0018】
この発明によれば、利用者が水栓を閉め止水した後、強制的に吐水管内の残留水が外部に排出されるために、使用後吐水管から水が滴らないようになる。
【0019】
【発明の実施の形態】
本発明の請求項1記載の発明は、アルカリイオン水及び酸性イオン水を生成する電極板を有する電解槽と、前記電解槽に一端を接続され他端を原水管に接続される通水路と、前記通水路の通水状態を検知する流量センサと、前記電解槽の一室の上端に接続され生成されたイオン水を吐水する吐水管と、前記電解槽の他室の上端に接続された生成されたイオン水を通水する通水管と、前記通水管に接続された酸性イオン水を吐水する酸性水専用吐水管と、前記吐水管および前記酸性水専用吐水管より下方に出口が位置し前記電解槽の水を排水する排水管と、前記通水管及び前記排水管の流路に設けられた弁装置と、前記流量センサの信号によって前記弁装置を開閉する制御手段とを備え、前記制御手段は前記流量センサで前記通水路の止水を検知したとき前記弁装置を一定時間開放し、前記通水管及び前記吐水管内の残留水を前記排水へ導き排出する機構が、重力により前記通水管及び前記吐水管内の残留水を自動的に排出し、前記電解槽内の水位を前記電解槽内の電極板の上端付近となるようにするアルカリイオン整水器である。
【0020】
これによって、利用者が水栓を閉めて止水した後、強制的に吐水管内の残留水が外部に排出されるようになる。
【0021】
発明は、前記弁装置の開放により通水管及び吐水管内の残留水を排出する機構が、重力により前記通水管および前記吐水管内の残留水を自動的に排出するようにしたもので、これによって比較的簡単な機構によって上記目的を達成できる。
【0022】
発明は、前記弁制御手段により、前記電解槽内の水位を前記電解槽内の電極板の上端付近となるようにしたもので、これによって、仮に排水管に設けられた電磁弁等が開いた場合にも、電解槽内の水が外部に排出されることがなくなる。
【0023】
以下本発明の実施の形態について図面を参照しながら説明する。
図1は本発明の実施の形態におけるアルカリイオン整水器の概略構造図、図2は図1に示すアルカリイオン整水器の制御ブロック図、図3は同じく概略制御フロー図である。なお、以下に示す実施の形態においては、先に説明した従来のアルカリイオン整水器の各部材に対応するものには同じ符号を付している。
【0024】
図1を参照して、1は水道水などの原水管、2は水栓、3はアルカリイオン整水器、4は浄水部、5は流量センサ、10,11は電極板、12は通水管、13は吐水管、14は電磁弁(酸性水用)、15は酸性水専用吐水管、16は電磁弁(排水用)、17は排水管、18は電源投入用プラグ、19は電源部、31は制御手段、21は操作表示部である。図1の状態で水位Aは、通水管12の呑み口よりも下方、すなわち、利用者が水栓2で止水したとき、吐水管13から水が滴らない水位としている。
【0025】
図2を参照して、30は本発明の実施の形態のMPU、23は流量検知部、24は操作表示制御部、25は電解槽制御部、26は電磁弁制御部、29は電解槽制御部25及び電磁弁制御部26の制御時間を管理するMPU22内にあるタイマーである。また、28は、流量センサ5の信号により流量検知部23で止水を検知した時点で、電磁弁制御部26に指令を出し一定時間排水する電磁弁制御手段である。
【0026】
次に以上のように構成されたアルカリイオン整水器3について、図1、図2、及び図3の概略制御フローに基づき動作を説明する。
【0027】
利用者が操作表示部21によりアルカリイオン水の生成モードを設定する(STEP1)と、利用者の設定内容およびアルカリイオン整水器3の現在の動作状態が操作表示部に表示される(STEP2)。次に利用者が水栓2を開くことにより、水栓2から通水された原水は、浄水部4で原水中の残留塩素の臭いや一般細菌などの不純部が取り除かれ、流量センサ5を通過し流量検知部23による通水を検知し、通水ありと通水なしに振り分けられる(STEP3)。
【0028】
通水を検知した場合、利用者が設定した生成モードに従って、制御内容が振り分けられる(STEP4)。使用者がSTEP1でアルカリイオン水の生成モードに設定した場合、電磁弁16(排水用)を閉じ、電磁弁14(酸性水用)を開く(STEP5、STEP6)。さらに、流量センサ5を通過した水はカルシウム供給部6を経て電解槽8に通水される。
【0029】
電解槽8に通水された水は、電解槽制御部25により電極板10,11の極性と電解の強さを制御し電解を開始する(STEP7)。電解槽8で生成されたアルカリイオン水は吐水管13を経て外部に吐水される。一方、電解槽8で生成された酸性イオン水は、通水管12、電磁弁14(酸性水用)、酸性水専用吐水管15を経て排水される。
【0030】
利用者がSTEP1で酸性水の生成モードに設定した場合には、電磁弁14(酸性水用)を閉じ、電磁弁16(排水用)を開く(STEP8、STEP9)。電解槽8に通水された水は、電解槽制御部25により電極板10,11の極性と電解の強さを制御し電解を開始する(STEP10)。電解槽8で生成された酸性イオン水は吐水管13を経て吐水される。一方、電解槽8で生成されたアルカリイオン水は電磁弁14(酸性水用)が閉じているため、通水管12、電磁弁16(排水用)を経て吐水される。
【0031】
また、利用者がSTEP1で浄水モードに設定した場合は、電磁弁16(排水用)と電磁弁14(酸性水用)を閉じる(STEP11、STEP12)。電解槽8に通水された水は、電解槽制御部25により電解を停止するため(STEP13)、そのまま吐水管13を経て吐水される。以上までの動作は従来例と同様である。
【0032】
ここで、利用者が水栓2を閉め、原水通水を停止した場合、流量センサ5の信号により流量検知部23は通水していないと判断する(STEP3)。次に電磁弁制御手段28によって一定時間(本実施の形態では1〜2秒)電磁弁14(酸性水用)及び電磁弁16(排水用)を共に開く(STEP22)。これによって、図1に示す吐水管13内の残留水は電解槽8内に引き込まれ、水位A(電極板10,11の上端付近)になるまで止水弁7(メカ弁)、通水管12、電磁弁16(排水用)、排水管17を通過して外部に排水される。
【0033】
このとき、排水管17は酸性水専用吐水管15より低い位置にあるため、電磁弁14(酸性水用)を同時に開けることにより、酸性水専用吐水管15内の水は、通水管12側に引き込まれ、排水管17を通過して外部に排水されることとなる。次に、水位A(電極10,11の上端付近)まで水位が下がった時点で電磁弁14(酸性水用)及び電磁弁16(排水用)を共に閉じる。この状態では、吐水管13及び酸性専用吐水管15内の水はほとんど残っておらず、これによって、使用後に、吐水管13や酸性専用吐水管15から水が滴り落ちることがなくなる。
【0034】
なお、STEP14〜STEP19については、上記した従来のアルカリイオン整水器の動作と同じであるため、説明を省略する。
【0035】
【発明の効果】
以上のように本発明のアルカリイオン整水器によれば、利用者が水栓を閉めた後、吐水管及び酸性専用吐水管の出口からの水の滴り落ちを防止することができ、利用者に不快感を与えないアルカリイオン整水器を提供することができる。

[0006]
Next, based on the block diagram shown in FIG. 5, the details of the control means 20 of the alkaline water conditioner 3 will be described. Reference numeral 22 denotes an MPU (microprocessor unit) provided in the control means 20 for giving an operation instruction to each control unit described later. Reference numeral 23 denotes a flow detection unit that transmits a signal from the flow sensor 5 to the MPU 22, 24 denotes an operation display control unit that transmits the operation content of the operation display unit 21 to the MPU 22, and displays the operation display unit 21 in accordance with the instruction of the MPU 22.

[0007]
Next, the operation of the alkali ion water conditioner 3 having the above configuration will be described based on the schematic control flows of FIGS.
[0008]
When the user sets the generation mode of the alkaline ionized water on the operation display unit 21 (STEP 1), the setting contents of the user and the current operation state of the alkali ion water conditioner 3 are displayed on the operation display unit 21 (STEP 2). ). Next, when the user opens the faucet 2, impurities such as residual chlorine odor and general bacteria in the raw water are removed from the raw water passed through the faucet 2 by the water purification unit 4, and the water is located downstream of the raw water. It passes through the flow sensor 5. The flow rate detection unit 23 detects the presence or absence of water passage, and is classified as having water passage detection and not having water passage detection (STEP 3).
[0009]
If there is water flow detection, the control content is sorted according to the generation mode set by the user (STEP 4). When the user sets the generation mode of alkaline ionized water in STEP1, the electromagnetic valve 16 (for drainage) is closed, and the electromagnetic valve 14 (for acidic water) is opened (STEP5, STEP6). Further, the water that has passed through the flow sensor 5 is passed through the calcium supply unit 6 to the electrolytic cell 8.
[0010]
Here, the water stop valve 7 (mechanical valve) is automatically closed by the water pressure when water is passed. The water passed through the electrolytic cell 8 controls the polarities of the electrode plates 10 and 11 and the strength of the electrolytic treatment by the electrolytic cell control unit 25 to start the electrolytic treatment (STEP 7). The alkaline ionized water generated in the electrolytic cell 8 is discharged to the outside via a water discharge pipe 13. On the other hand, the acidic ion water generated in the electrolytic cell 8 is drained through a water pipe 12, a solenoid valve 14 (for acidic water), and a water discharge pipe 15 for acidic water.
[0011]
When the user has set the acidic water generation mode in STEP 1, the electromagnetic valve 14 (for acidic water) is closed and the electromagnetic valve 16 (for drainage) is opened (STEP 8 and STEP 9). The water passed through the electrolytic cell 8 controls the polarity of the electrode plates 10 and 11 and the strength of the electrolytic treatment by the electrolytic cell control unit 25 to start the electrolytic treatment (STEP 10). The acidic ion water generated in the electrolytic cell 8 is discharged through a water discharge pipe 13. On the other hand, the alkaline ion water generated in the electrolytic cell 8 is discharged through the water pipe 12 and the electromagnetic valve 16 (for drainage) because the electromagnetic valve 14 (for acidic water) is closed.
[0012]
When the user sets the water purification mode in STEP1, the solenoid valve 16 (for drainage) and the solenoid valve 14 (for acid water) are closed (STEP11, STEP12). The water passed through the electrolytic cell 8 is discharged through the water discharge pipe 13 as it is to stop the electrolysis by the electrolytic cell control unit 25 (STEP 13). On the other hand, since the solenoid valve 14 (for acidic water) is closed, the water in the water pipe 12 is not discharged to the outside.
[0013]
Here, when the user closes the faucet 2 to stop the flow of the raw water, the flow detection unit 23 determines that there is no water flow based on the signal of the flow sensor 5 (STEP 3). Next, it is determined whether or not the condition for cleaning the electrolytic bath 8 is satisfied and there is a cleaning request (STEP 14). When there is no cleaning request, both the electromagnetic valve 14 (for acidic water) and the electromagnetic valve 16 (for drainage) are closed (STEP 11 and STEP 12), and the electrolysis in the electrolytic cell 8 is stopped (STEP 13).
[0014]
If there is a cleaning request in step 14, it is next determined whether there is a request to remove water from the electrolytic cell 8 (STEP 15). If there is no drainage request, both the electromagnetic valve 14 (for acidic water) and the electromagnetic valve 16 (for drainage) are closed (STEP 16 and STEP 17), and the electrolytic cell control unit 25 starts electrolysis for cleaning of the electrolytic cell 8 (STEP 16). (STEP 18). The electrolysis time for cleaning is managed by the timer 27, and when the cleaning time is over, a drainage request is made (STEP 19). On the other hand, if there is a drainage request after washing, it is determined in STEP15 that there is a drainage request, and the solenoid valve 16 (for drainage) is opened (STEP20). The drainage time is managed by the timer 27, and when the drainage is completed, the cleaning and drainage requests are cleared (STEP 21). In addition, during drainage, in order to stop the electrolysis in the electrolytic cell 8, the electrolytic cell 8 is passed through STEP 13.
[0015]
[Problems to be solved by the invention]
As described above, in the conventional alkali ion water purifier, when the user does not request cleaning after closing the faucet 2, both the electromagnetic valves 14 and 16 are immediately closed by the signal of the flow rate sensor 5, so that the water discharge pipe 13 and Water remained in the acidic water spouting pipe 15, and the remaining water dripped, giving the user discomfort.
[0016]
Therefore, an object of the present invention is to provide an alkali ion water conditioner in which water does not drip from an outlet of a water discharge pipe and an acidic water discharge pipe after use.

And the valve device is opened a predetermined time when the said water passage tube and the water discharge pipe mechanism residual water discharged-out guide to the drain pipe of automatically discharging the residual water in the water passage tube and the water discharge pipe by gravity And an alkali ion water conditioner in which the water level in the electrolytic cell is near the upper end of the electrode plate in the electrolytic cell .
[0020]
Thus, after the user closes the faucet and stops the water, the residual water in the water discharge pipe is forcibly discharged to the outside.
[0021]
According to the present invention, the mechanism for discharging the residual water in the water pipe and the water discharge pipe by opening the valve device automatically discharges the residual water in the water pipe and the water discharge pipe by gravity. The above object can be achieved by a relatively simple mechanism.
[0022]
The present invention is such that the water level in the electrolytic cell is set near the upper end of the electrode plate in the electrolytic cell by the valve control means, whereby an electromagnetic valve or the like provided in the drain pipe is opened. In this case, the water in the electrolytic cell is not discharged to the outside.
[0023]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In addition, in the embodiment shown below, the same reference numerals are given to components corresponding to each member of the above-described conventional alkali ion water purifier described above.
[0024]
Referring to FIG. 1, 1 is a raw water pipe for tap water, 2 is a faucet, 3 is an alkali ion water conditioner, 4 is a water purification section, 5 is a flow sensor, 10 and 11 are electrode plates, and 12 is a water pipe. , 13 is a water discharge pipe, 14 is a solenoid valve (for acid water), 15 is a water discharge pipe dedicated to acid water, 16 is a solenoid valve (for drainage), 17 is a drain pipe, 18 is a power-on plug, 19 is a power supply section, 31 is a control means, 21 is an operation display unit. In the state of FIG. 1, the water level A is lower than the drinking opening of the water pipe 12, that is, the water level at which water does not drip from the water discharge pipe 13 when the user stops the water with the faucet 2.
[0025]
Referring to FIG. 2, reference numeral 30 denotes an MPU according to the embodiment of the present invention, reference numeral 23 denotes a flow rate detection unit, reference numeral 24 denotes an operation display control unit, reference numeral 25 denotes an electrolytic cell control unit, reference numeral 26 denotes an electromagnetic valve control unit, and reference numeral 29 denotes an electrolytic cell control unit. This is a timer in the MPU 22 that manages the control time of the unit 25 and the solenoid valve control unit 26. Reference numeral 28 denotes an electromagnetic valve control unit that issues a command to the electromagnetic valve control unit 26 and drains water for a certain period of time when the flow detection unit 23 detects water stoppage based on a signal from the flow sensor 5.
[0026]
Next, the operation of the alkali ion water conditioner 3 configured as described above will be described based on the schematic control flows of FIGS. 1, 2, and 3.
[0027]
When the user sets the generation mode of the alkaline ionized water on the operation display unit 21 (STEP 1), the set contents of the user and the current operation state of the alkali ion water conditioner 3 are displayed on the operation display unit (STEP 2). . Next, when the user opens the water faucet 2, the raw water passed through the water faucet 2 is cleaned by the water purification unit 4 to remove impurities such as residual chlorine odor and general bacteria in the raw water. The flow is detected by the flow detecting unit 23 when the water passes and the water is separated with and without water (STEP 3).
[0028]
When the passage of water is detected, the control contents are sorted according to the generation mode set by the user (STEP 4). When the user sets the generation mode of alkaline ionized water in STEP1, the electromagnetic valve 16 (for drainage) is closed, and the electromagnetic valve 14 (for acidic water) is opened (STEP5, STEP6). Further, the water that has passed through the flow sensor 5 is passed through the calcium supply unit 6 to the electrolytic cell 8.
[0029]
The water passed through the electrolytic cell 8 controls the polarities of the electrode plates 10 and 11 and the strength of the electrolytic treatment by the electrolytic cell control unit 25 to start the electrolytic treatment (STEP 7). The alkaline ionized water generated in the electrolytic cell 8 is discharged to the outside via a water discharge pipe 13. On the other hand, the acidic ion water generated in the electrolytic cell 8 is drained through a water pipe 12, a solenoid valve 14 (for acidic water), and a water discharge pipe 15 for acidic water.
[0030]
When the user has set the acidic water generation mode in STEP 1, the electromagnetic valve 14 (for acidic water) is closed and the electromagnetic valve 16 (for drainage) is opened (STEP 8 and STEP 9). The water passed through the electrolytic cell 8 controls the polarity of the electrode plates 10 and 11 and the strength of the electrolytic treatment by the electrolytic cell control unit 25 to start the electrolytic treatment (STEP 10). The acidic ion water generated in the electrolytic cell 8 is discharged through a water discharge pipe 13. On the other hand, the alkaline ionized water generated in the electrolytic cell 8 is discharged through the water pipe 12 and the electromagnetic valve 16 (for drainage) because the electromagnetic valve 14 (for acidic water) is closed.
[0031]
When the user sets the water purification mode in STEP1, the solenoid valve 16 (for drainage) and the solenoid valve 14 (for acid water) are closed (STEP11, STEP12). The water passed through the electrolytic cell 8 is discharged through the water discharge pipe 13 as it is to stop the electrolysis by the electrolytic cell control unit 25 (STEP 13). The operation up to the above is the same as in the conventional example.
[0032]
Here, when the user closes the faucet 2 and stops the flow of the raw water, the flow detection unit 23 determines from the signal of the flow sensor 5 that the water is not flowing (STEP 3). Next, the electromagnetic valve control means 28 opens both the electromagnetic valve 14 (for acid water) and the electromagnetic valve 16 (for drainage) for a fixed time (1-2 seconds in the present embodiment) (STEP 22). As a result, the residual water in the water discharge pipe 13 shown in FIG. 1 is drawn into the electrolytic cell 8, and the water stop valve 7 (mechanical valve) and the water flow pipe 12 are brought to a water level A (near the upper ends of the electrode plates 10, 11). The water is drained to the outside through a solenoid valve 16 (for drainage) and a drain pipe 17.
[0033]
At this time, since the drain pipe 17 is located at a position lower than the acidic water discharge pipe 15, by simultaneously opening the solenoid valve 14 (for acidic water), the water in the acidic water discharge pipe 15 is moved to the water pipe 12 side. It will be drawn in and will be drained outside through the drain pipe 17. Next, when the water level drops to the water level A (near the upper ends of the electrodes 10 and 11), both the electromagnetic valve 14 (for acidic water) and the electromagnetic valve 16 (for drainage) are closed. In this state, almost no water remains in the water discharge pipe 13 and the acidic water discharge pipe 15, so that water does not drip from the water discharge pipe 13 or the acid water discharge pipe 15 after use.
[0034]
Steps 14 to 19 are the same as the operation of the above-described conventional alkali ion water conditioner, and thus the description thereof is omitted.
[0035]
【The invention's effect】
