The present invention is a water spouting apparatus () that discharges water with reciprocal motion, and has a water spouting apparatus body () and a oscillation generating element (). The oscillation generating element includes a water supply conduit (), a collision part () that generates a vortex on the downstream side, a vortex street conduit () provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member () on which the upstream side is formed and the downstream member () on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H) is higher than the height (H) of the vortex street at the downstream end of the upstream member.

Water spouting apparatus

Summary Problem: To provide a spout apparatus in which sagging of the mesh structure portion in the flow-conditioning member due to water pressure can be suppressed even if the flow-conditioning member is formed by a fine diameter mesh structure, and the flow-conditioning member can be compactly constituted and flow velocity distribution made uniform. Solution Means: The embodiment of the invention is a spout apparatus, including a spout apparatus main unit, a flow-conditioning member, and a spray member; wherein the flow-conditioning memberis formed by a mesh structure in which numerous fine holes are formed, and the mesh structure is layered and formed three dimensionally, such that the mesh structure portion of at least a portion of the mesh structure extends in a direction parallel to the direction of water flowing into the flow-conditioning member.

Provided is a water discharge device for spraying water having transparency throughout a long distance. The present invention is a water discharge device () that sprays the supplied water, and includes a water discharge device body (), a rectifying chamber () which is provided in the water discharge device body, a plurality of rectifying members () that are disposed at intervals in the rectifying chamber and includes a number of fine holes (), so that water sequentially passes through the plurality of rectifying members, a water spray member () provided with spray nozzles () for discharging the water passing through these rectifying members, and an air bubble discharge flow path () that is formed so that air bubbles present among the rectifying members bypass at least one of the rectifying members to reach the water spray member, and has a larger flow path sectional area than the fine holes.

Water discharge device

A water spouting device has a shower flow passage. A guide wall is formed in the shower flow passage. The guide wall turns only a part of a water stream flowing in from an inflow port into a guiding water stream directed to the outside.

Water spouting device

The present invention provides a water spouting device which enables air bubble entrained water with an increased entrainment rate of air bubbles to be discharged at a low flow rate stage even though the user adjusts the flow rate based on the same feeling as that for a conventional water spouting device, the present water spouting device further enabling, at a high flow rate stage, prevention of discharge of air bubble entrained water with such a total amount as makes the user feel that the resultant amount of water significantly exceeds that intended by the user. A spout cap BC serving as the present water spouting device includes a pressure reducing portionserving as an entrainment rate adjusting portion to adjust the entrainment rate of air bubbles entrained in air bubble entrained water in an air bubble entraining portion. The pressure reducing portionserving as the entrainment rate adjusting portion increases the entrainment rate until inflow water from an inflow portreaches a predetermined flow rate, and suppresses an increase in entrainment rate when the inflow water from the inflow portexceeds the predetermined flow rate.
