  • Patent number: 11821186
    Abstract: 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 2, including a spout apparatus main unit 6, a flow-conditioning member 12, and a spray member 16; wherein the flow-conditioning member 12 is 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.

  • Patent number: 10626584
    Abstract: Provided is a water discharge device for spraying water having transparency throughout a long distance. The present invention is a water discharge device (2) that sprays the supplied water, and includes a water discharge device body (6), a rectifying chamber (14a) which is provided in the water discharge device body, a plurality of rectifying members (18) that are disposed at intervals in the rectifying chamber and includes a number of fine holes (18a), so that water sequentially passes through the plurality of rectifying members, a water spray member (20) provided with spray nozzles (22b) for discharging the water passing through these rectifying members, and an air bubble discharge flow path (26) 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.
