Abstract: The present invention is a spout apparatus (1) for spouting water, including: a spout apparatus main body (2) and an oscillation inducing element wherein the oscillation inducing element (4) has: a water supply conduit (10a), a water collision portion (14) disposed on the downstream end portion of the water supply passageway, for alternately generating oppositely circulating vortexes on that downstream side; a vortex street passageway (10b) for guiding vortexes formed by the water collision portion while causing them to grow; and a flow aligning pathway (10c) for aligning water including vortexes guided by the vortex street passageway, and causing it to be discharged; wherein a pair of opposing wall surfaces in the vortex street passageway is constituted so that the downstream side thereof is tapered over a longer area than the flow-aligning passageway, such that the flow path cross section thereof narrows toward the downstream side.

Abstract: The present invention is a spout apparatus (1) for discharging water, including a spouting apparatus main body (2) and an oscillation inducing element (4) for discharging water with reciprocating motion; wherein the oscillation inducing element has: a water supply passageway (10a); a water colliding portion (14) for generating vortexes of mutually opposing circulations at the downstream side thereof by the collision of hot or cold water; a vortex street passageway (10b) having a tapered part, placed on the downstream side of the water supply passageway, which narrows in flow path cross section toward the downstream side; a separating portion (12) for suppressing the Coanda effect acting on the flow of water along the wall surface of a vortex street passageway; and a flow-aligning passageway (10c) having an essentially fixed flow path cross section which aligns the flow of hot or cold water which has passed through the separating portion.

Abstract: Provided is a shower apparatus which can stably supply bubbly water through all nozzle holes and can cause water droplets of large, uniform size to land continuously on the user so as to allow the user to enjoy a shower with a voluminous feel as if the user were being showered by large drops of rain. The shower apparatus includes a water supply unit, a throttle unit adapted to eject passing water downstream, an aeration unit adapted to produce bubbly water by aerating the water ejected through the throttle unit, and a nozzle unit provided with a plurality of nozzle holes used to discharge the bubbly water, wherein the throttle unit has a flat-shaped throttle channel and water ejected through the throttle channel plunges into an air-liquid interface as a sheet-like stream, thereby producing bubbly water, which is then discharged through the nozzle hole.
Abstract translation: 本发明提供一种能够稳定地通过所有喷嘴孔供给气泡水并能够使大尺寸均匀的水滴在使用者上连续着陆的淋浴装置，以使使用者能够像使用者一样享受大量的淋浴 被大滴雨淋淋。 淋浴装置包括供水单元，适于在下游喷射通过的水的节气门单元，适于通过对通过节流单元喷射的水进行充气来产生气泡水的曝气单元，以及设置有多个喷嘴孔的喷嘴单元， 排出气泡水，其中节气门单元具有平坦的节流通道，并且通过节流通道喷射的水作为片状流而进入空气 - 液体界面，从而产生气泡水，然后通过喷嘴孔 。
