WATER DISCHARGE DEVICE

Japanese Patent JP2023125078

A

To provide a water discharge device which can sufficiently suppress an abnormal sound generated from a vibration generation element.SOLUTION: A water discharge device (1) for discharging water while vibrating water in a reciprocating manner comprises: a water discharge device body (10); and a vibration generation element (22). The vibration generation element comprises: a water supply passage (24); a collision part (30) with which water guided by the water supply passage collides; a vortex train passage (26) which guides a vortex formed by the collision part; and a discharge passage (28) which discharges water. The vortex train passage is formed by fitting an upstream side fitting part (18a) of an upstream side member (18) to a downstream side fitting part (20a) of a downstream side member (20). The upstream side member or downstream side member includes a vibration suppression part (18b) which suppresses the vibration of the upstream side member due to the vortex generated in the vortex train passage. When fitting the upstream side fitting part to the downstream side fitting part, the upstream side fitting part or the downstream side fitting part is elastically deformed by a prescribed amount by providing the vibration suppression part.SELECTED DRAWING: Figure 7
