1. A water spouting device which generates and spouts air bubble-entrained water by plunging water through an air-liquid interface between air and temporarily stored water, the water spouting device comprising: a first member which has an inflow port through which water flows in from a water supply source and which jets the water toward a downstream side; and a second member which has: a straight stream spout which spouts air bubble-entrained water as a single unified water stream; a shower spout which spouts air bubble-entrained water in the form of a shower; a straight stream flow passage extending from the inflow port side to the straight stream spout; and a shower flow passage extending from the inflow port side to the shower spout, wherein the straight stream spout and the shower spout are disposed in coaxial circles, changing the relative positional relation between the first member and the second member by rotating any one of the first member and the second member can switch between a first state, in which water flows through the straight stream flow passage and air is entrained into this water, and a second state, in which water flows through the shower flow passage and air is entrained into this water, the inflow port is eccentrically disposed relative to the center of the shower spout in the radial direction, and a dispersed water stream forming part is formed in the shower flow passage, the dispersed water stream forming part turning a part of a water stream flowing in from the inflow port into a guiding water stream, which flows toward the other end side in the radial direction of the shower spout, by causing it to crash against a guide wall, while turning the rest of the water stream into a directly advancing water stream, which flows toward the one end side in the radial direction of the shower spout, without causing it to crash against the guide wall and an inner wall surface of the shower flow passage, and merging the guiding water stream and the directly advancing water stream to form a dispersed water stream. |
