SPOUT APPARATUS

摘要

The present invention is a spout apparatus (1), including: a shower head main body (2), and an oscillation inducing element (4) for discharging water while allowing it to oscillate reciprocally, wherein the oscillation inducing element includes: a water supply passageway (10a), a water collision portion (14) for generating vortexes of alternately mutually opposing circulations; a vortex street passageway (10b) for guiding and growing vortexes formed by the water collision portion; a discharge passageway (10c) for causing water guided by the vortex street passageway to be discharged; a bypass passageway (6b) for allowing water to detour the water collision portion and flow into the vortex street passageway; and a flow volume ratio adjusting member (8), capable of varying the flow volume ratio of water flowing into the vortex street passageway through the water collision portion to water flowing into the vortex street passageway through the bypass passageway.

1. A spout apparatus for discharging hot or cold water with reciprocal motion at a variable amplitude from a spouting port, comprising:
a spout apparatus main body; and an oscillation inducing element disposed on the spout apparatus main body for discharging supplied hot or cold water with a reciprocal motion; wherein the oscillation inducing element comprises: a water supply passageway into which water supplied from the spout apparatus main body flows; a water collision portion disposed on a downstream end portion of the water supply passageway so as to block a portion of a cross-section of the water supply passageway, the water collision portion alternately produces oppositely circulating vortexes on the downstream side of the water collision portion by colliding with hot or cold water guided by the water supply passageway; a vortex street passageway disposed on a downstream side of the water supply passageway for guiding and growing the vortexes formed by the water collision portion; a discharge passageway disposed on a downstream side of the vortex street passageway for discharging hot or cold water guided by the vortex street passageway; a bypass passageway for causing hot or cold water supplied from the spout apparatus main body to flow into the vortex street passageway, detouring the water collision portion; and a flow volume ratio changing portion, capable of changing the flow volume ratio of hot or cold water flowing into the vortex street passageway through the water collision portion to hot or cold water flowing into the vortex street passageway through the bypass passageway.
