Drain neutralizer



【課題】給湯器の制御部側で水位の異常上昇を確実に検知可能なドレン中和器を提供すること。 【解決手段】給湯器1の熱交換器4へ繋がるドレン入口71を備えたドレン中和器であって、ドレン入口71の近傍には、一対の水位検知用の電極76が横並びに設けられ、それらの電極76のうち、ドレン入口71から遠い側の第1の電極76Aの下端761が、ドレン入口71に近い側の第2の電極76Bの下端762より下位となるように配置された。 【選択図】図2
PROBLEM TO BE SOLVED: To provide a drain neutralizer capable of reliably detecting an abnormal water level increase in a control part side of a water heater.SOLUTION: The drain neutralizer provided with a drain inlet 71 connected to a heat exchanger 4 of the water heater 1 transversely arranges a pair of water level detecting electrodes 76 in the neighborhood of the drain inlet 71, and is arranged so that a lower end 761 of a first electrode 76A distant from the drain inlet 71 out of the electrodes 76 is at a lower level than a lower end 762 of a second level 76B near to the drain inlet 71.
