Title:
WATER DISCHARGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/106370
Kind Code:
A1
Abstract:
The present invention provides a water discharging device that is capable of sufficiently suppressing noise produced by a vibration generating element. The present invention is a water discharging device (1) that discharges water while causing reciprocating vibration of the water, said water discharging device (1) being characterized by comprising a water discharging device body (10) and a vibration generating element (22), wherein: the vibration generating element is provided with a water supply passage (24), a collision part (30) with which water that has been guided by the water supply passage collides, a vortex row passage (26) which guides vortexes that are created by the collision part, and a discharge passage (28) which is for discharging water; the vortex row passage is configured by fitting together an upstream-side fitting part (18a) of an upstream-side member (18) and a downstream-side fitting part (20a) of a downstream-side member (20); provided to the upstream-side member or the downstream-side member is a vibration suppression part (18b) which suppresses vibration of the upstream-side member caused by vortexes occurring in the vortex row passage; and when the upstream-side fitting part and the downstream-side fitting part are fitted together, the upstream-side fitting part or the downstream-side fitting part undergoes a prescribed amount of elastic deformation due to the provision of the vibration suppression part.
