PROBLEM TO BE SOLVED: To provide a water discharge device capable of securing a large quantity of suction air even when a water discharge port such as a massage nozzle is provided at a center of a water spray surface.SOLUTION: A water discharge device SH includes, at a throttle part 42, a plurality of mutually independent throttle flow passages 421 juxtaposed at some intervals apart from each other into a circular shape. A plurality of air mixing chambers 432 functioning as connection flow passages extending from an air mixing part 43 to a water spray part 44 are provided along jetting direction of acceleration jet flows AFa radially jetted from the throttle flow passages 421. Backflow prevention walls 451 are provided in each space between the plurality of air mixing chambers 432 for preventing backflow of water from the water spray part 44 side to an air introduction port 431 side.COPYRIGHT: (C)2014,JPO&INPIT【課題】散水面の中央にマッサージノズルといった吐水口を設けた場合であっても吸引空気量を大きく確保できる吐水装置を提供すること。【解決手段】吐水装置SHは、絞り部42では、複数の互いに独立した絞り流路421が互いに間隔をおいて円状に複数並設され、空気混入部43から散水部44に至る接続流路として機能する空気混入室432は、絞り流路421から放射状に噴射される加速噴流AFaの噴射方向に沿って複数設けられており、複数の空気混入室432の各々の間に、散水部44側から空気導入口431側に水が逆流することを防止するための逆流防止壁451が設けられている。【選択図】図4
