吐水装置
Document Type and Number:
Japanese Patent JP6827647
Kind Code:
B2
Abstract:
To provide a water discharge device which can be composed compactly with a simple structure, and which allows easy-to-handle water discharge to be achieved.SOLUTION: A water discharge device (1) for discharging hot water while reciprocating it includes a water discharge device body (2) and a vibration generation element (4) for vibrating hot water. The vibration generation element includes a water supply passage (10a), a hot water collision part (14) disposed so as to occlude part of the flow passage cross section of the water supply passage for generating vortexes in directions opposite to each other on the downstream side, a vortex street (10b) having a tapered part for guiding the formed vortexes while growing them, a peeling part (12) for suppressing a Coanda effect acting on the flow of the hot water along a wall surface of the vortex street, a first straightening part (10c) for suppressing the disorder in a direction parallel or orthogonal to a vibration plane, and a second straightening part (10d) for suppressing the disorder in a direction orthogonal to the vibration plane.SELECTED DRAWING: Figure 4A
