DISCHARGING DEVICE
To provide a discharge device that can reliably prevent water added with additives from being sucked upstream.SOLUTION: A discharge device 1 comprises a water passage part 2, an addition part (foam supply unit 3), an air intake part 60 and a drain part 70. The water passage part 2 circulates water supplied from an upstream side and supplies the water to a downstream side discharge part (shower head 102). The foam supply unit 3 is provided in the water passage part 2. The foam supply unit 3 adds an additive (liquid cleaning agent) to the water flowing through the water passage part 2. The air intake part 60 is provided in the water passage part 2 located at the upstream side of the foam supply unit 3. The air intake part 60 has an air intake channel (air introduction hole 65B, gap 66A) that is closed when the water is flowing and is opened when the water is stopped. The drain part 70 is provided in the water passage part 2 between the air intake part 60 and the foam supply unit 3 and is disposed below the air intake part 60. The drain part 70 has a drainage channel (water discharge hole 75B, gap 76A) that is closed when the water is flowing and is opened when the water is stopped.SELECTED DRAWING: Figure 1
【課題】添加物が添加された水が上流側に吸引されることを確実に防止できる吐出装置を提供する。【解決手段】吐出装置１は、通水部２と、添加部（泡供給ユニット３）と、吸気部６０と、排水部７０とを備える。通水部２は、上流側から供給される水を流通させて下流側の吐出部（シャワーヘッド１０２）に供給する。泡供給ユニット３は、通水部２に設けられる。泡供給ユニット３は、通水部２を流通する水に添加物（液体洗浄剤）を添加する。吸気部６０は、泡供給ユニット３よりも上流側の通水部２に設けられる。吸気部６０は、通水時に閉塞されて止水時に開放される吸気路（空気導入孔６５Ｂ、隙間６６Ａ）を有する。排水部７０は、吸気部６０と泡供給ユニット３との間の通水部２に設けられるとともに吸気部６０よりも下方に配置されている。排水部７０は、通水時に閉塞されて止水時に開放される排水路（水排出孔７５Ｂ、隙間７６Ａ）を有する。【選択図】図１
