PROBLEM TO BE SOLVED: To provide a washing device for a bathroom washing place floor, capable of suppressing generation of mold on the bathroom washing place floor.SOLUTION: A water release device for a bathroom washing place floor includes: a nozzle part capable of independently sprinkling unprocessed water and modified water obtained by reducing a bacterium amount from the unprocessed water onto the bathroom washing place floor and a sprinkling control part for controlling sprinkling of the unprocessed water from the nozzle part, and sprinkling of the modified water from the nozzle part. The sprinkling control part executes: an organic matter removing step of allowing organic matters on the bathroom washing place floor to flow into an exhaust port together with the unprocessed water by sprinkling the unprocessed water from the nozzle part onto the bathroom washing place floor and a replacement step of replacing the unprocessed water on the bathroom washing place floor with the modified water by sprinkling the modified water from the nozzle part onto the bathroom washing place floor so as to allow the unprocessed water on the bathroom washing place floor to flow into the exhaust port.SELECTED DRAWING: Figure 23COPYRIGHT: (C)2019,JPO&INPIT【課題】浴室の洗い場床においてカビの発生を抑制することができる浴室洗い場床洗浄装置を提供すること。【解決手段】本発明は、未処理水と、前記未処理水のバクテリア量が低減された改質水と、を互いに独立に浴室洗い場床上に散水可能なノズル部と、前記ノズル部からの前記未処理水の散水と前記ノズル部からの前記改質水の散水とを制御する散水制御部と、を備える浴室洗い場床用吐水装置である。前記散水制御部は、前記ノズル部から前記浴室洗い場床上に前記未処理水を散水させることによって、前記浴室洗い場床上の有機物を前記未処理水と一緒に排水口に流す有機物除去工程と、前記有機物除去工程の後に、前記ノズル部から前記浴室洗い場床上に前記改質水を散水させることによって、前記浴室洗い場床上の前記未処理水を前記排水口に流すことで、前記浴室洗い場床上の前記未処理水を前記改質水に置換する置換工程と、を実施するようになっている。【選択図】図23
