WATER LEAKAGE SENSOR FOR WATER SUPPLY DEVICE AND WATER SUPPLY DEVICE
To provide a water leakage sensor for a water supply device having a space-saving and simple configuration capable of detecting different water leakage amounts in the water supply device.SOLUTION: A water leakage sensor for a water supply device comprises: a guide flow path defining member that defines a guide flow path for guiding water; a reference electrode terminal provided in the guide flow path; a first electrode terminal provided in the guide flow path and arranged a first distance away from the reference electrode terminal; and a second electrode terminal provided in the guide flow path and arranged a second distance away from the reference electrode terminal, which is longer than the first distance. The first electrode terminal and the reference electrode terminal are connected to a first detection circuit for detecting water flowing in the guide flow path based on a change in electrical resistance between the first electrode terminal and the reference electrode terminal. The second electrode terminal and the reference electrode terminal are connected to a second detection circuit for detecting water flowing in the guide flow path based on a change in electrical resistance between the second electrode terminal and the reference electrode terminal.SELECTED DRAWING: Figure 3
【課題】給水装置において異なる漏水量を検知することができる省スペースで簡易な構成の給水装置用漏水センサを提供する。【解決手段】給水装置用漏水センサは、水を案内する案内流路を画定する案内流路画定部材と、前記案内流路に設けられた参照用電極端子と、前記案内流路に設けられて前記参照用電極端子から第１距離離れて配置される第１電極端子と、前記案内流路に設けられて前記参照用電極端子から前記第１距離よりも長い第２距離離れて配置される第２電極端子と、を備える。前記第１電極端子と前記参照用電極端子とは、前記第１電極端子と前記参照用電極端子との間の電気抵抗の変化に基づいて前記案内流路に流れる水を検知するための第１検知回路に接続され、前記第２電極端子と前記参照用電極端子とは、前記第２電極端子と前記参照用電極端子との間の電気抵抗の変化に基づいて前記案内流路に流れる水を検知するための第２検知回路に接続される。【選択図】図３
