Abstract:
A water jetting device comprising a nozzle, for jetting from the nozzle cleansing water supplied thereto, wherein the nozzle has;an inflow chamber into which cleansing water flows, a water jetting body assembled in the inflow chamber, having a water jetting member comprising a cleansing water jetting spout and a chamber-housed member continuous with the water jetting member and situated within the inflow chamber, the water jetting body having a conduit for guiding cleansing water in the inflow chamber to the water jetting spout, and a water supply mechanism for guiding cleansing water into the inflow chamber in such a way that vortical flow around the chamber-housed member along the inside peripheral wall of the inflow chamber is created in cleansing water flowing into the inflow chamber, the water jetting body is assembled in the inflow chamber with the water jetting spout located in proximity to the exterior of the inflow chamber, such that the chamber-housed member is capable of swinging in an inclined attitude within the inflow chamber, the water supply mechanism generates a flow velocity differential in the vortical flow around the chamber-housed member, the force generated on the basis of the flow velocity differential exerting influence on the chamber-housed member whereby the chamber-housed member at an inclined attitude within the inflow chamber induces swinging motion and revolution of the water jetting body.
