Zusammenfassung: | To provide an ion elution unit capable of executing electrode wear detection at proper timing.SOLUTION: Since upper ends 90a of electrodes 90F, L and terminals 91 are on one side of electrodes F, L in an upper direction, and the terminals 91 are arranged so that a distance j between the terminals 91 is larger than a distance d between the electrodes 90F, L, when the electrode 90 is worn up to the vicinity of the terminal 91, a resistance value between the electrodes 90F, L increases, so that a voltage value applied to the electrode 90 rapidly increases, and the maximum voltage value is detected early and a speaker 75 gives a notification on the replacement of the electrode 90. Therefore, it is possible to give the notification on the replacement of the electrode 90 at proper timing regardless of water quality, and it is possible to prevent the notification on the replacement of the electrode 90 when the electrode 90 remains in a large amount or the electrode is worn to the position of the terminal 91 and water may leak from a case 80.SELECTED DRAWING: Figure 7
【課題】 電極の消耗検知を適切なタイミングで実施できるイオン溶出ユニットを提供する。【解決手段】 電極90F、Lの上端90a及び端子91が電極F、Lの一方側である上方向にあり、電極90F、L間の距離dよりも端子91間の距離jの方が大きくなるよう端子91を配置したので、電極90が端子91付近まで消耗したときにおける電極90F、L間の抵抗値が高まることで電極90へ印加する電圧値が急激に上昇し、早期に最大電圧値が検知されスピーカ75により電極90の交換が報知されるので、水質に依らず適切なタイミングで電極90の交換を報知することができ、電極90が多量に残存した状態や端子91まで消耗しケース80から水漏れする虞がある状態で電極90の交換が報知されることを阻止できる。【選択図】 図7 |
