PROBLEM TO BE SOLVED: To increase the amount of warm water or water flown into a passage separated from a base board, and accordingly, to increase the amount of mist generation, by placing a number of blades at intervals in the circumferential direction in gaps between blade wheel layers and forming the central opening of the blade wheel conical toward the base board. ;SOLUTION: In this mist generator, since the central opening 43d of a blade wheel is formed conical toward a base board 43a, the curvature of the flow line when warm water supplied from the upper side to the central opening 43d of the blade wheel is flown into a passage separated from the base board 43a is reduced compared to the case the central opening 43d is formed cylindrical. (In the figure the flow line in the case the central opening 43d is formed conical is shown in a solid line arrow mark, and that formed cylindrical in an alternate long and short dash line.) As a result, the amount of warm water flown from the central opening 43d to a separate flow passage increases and, accordingly, the amount of mist generation is also increased.;COPYRIGHT: (C)1998,JPO
