To provide a water discharging device which can improve the accuracy in measured water discharge.SOLUTION: A water discharging device 1 includes a water discharging unit 10, a water quantity measurement unit 41, a water information obtaining unit 54, electric-operated on/off valves (a first on/off valve 21 and a second on/off valve 22), and a controller 50. The water discharging unit 10 forms flow passages (a water supply flow passage 71, a hot water supply flow passage 72, an outflow flow passage 73, and a purified water flow passage 81). The water quantity measurement unit 41 measures an output value based on the quantity of water flowing in the flow passages. The water information obtaining unit 54 obtains information regarding water flowing in the flow passages (water information Iw). The electric-operated on/off valves open/close the flow passages. The controller 50 controls the driving of the electric-operated on/off valves. The controller 50 performs measured water discharge control in which the electric-operated on/off valves are driven according to the output value (a measured output value Vr) from the water quantity measurement unit 41 and the water information Iw obtained by the water information obtaining unit 54 so that a set water quantity Ws, which is set via operations on a water discharge quantity setting operation unit (a smart speaker 3), of water is discharged from the water discharging unit 10.SELECTED DRAWING: Figure 2 【課題】計量吐水における正確性の向上を図ることができる吐水装置を提供する。【解決手段】吐水装置１は、吐水部１０、水量計測部４１、水情報取得部５４、電動開閉弁（第１開閉弁２１、第２開閉弁２２）、及び制御部５０を備える。吐水部１０は流路（給水流路７１、給湯流路７２、流出流路７３、浄水用流路８１）を形成する。水量計測部４１は、流路を流れる水の水量に応じた出力値を計測する。水情報取得部５４は、流路を流れる水に関する情報（水情報Ｉｗ）を取得する。電動開閉弁は流路を開閉する。制御部５０は電動開閉弁の駆動を制御する。制御部５０は、吐水量設定操作部（スマートスピーカー３）の操作によって設定される設定水量Ｗｓを吐水部１０から吐水するように、水量計測部４１の出力値（実測出力値Ｖｒ）と、水情報取得部５４が取得する水情報Ｉｗとに基づいて、電動開閉弁を駆動する計量吐水制御を実行する。【選択図】図２
