吐水装置
Document Type and Number:
Japanese Patent JP7356633
Kind Code:
B2
Abstract:
To provide a water discharge device comprising a vibration generation element whose type is such that a contraction passage is formed in which at least a part of a water discharge hole passage is contracted in a taper shape from a side of a vortex generation passage toward a water discharge hole side, the water discharge device capable of eliminating elastic deformation of the taper shaped contraction passage in at least a production time.SOLUTION: A water discharge device comprises a vibration generation element for reciprocating and vibrating hot water or water for discharging hot water or water, and the vibration generation element comprises a water feeding passage 20, a water/hot water collision part 26, a vortex generation passage 22, a water discharge hole passage 24, and a water discharge hole 28. The water discharge hole passage has a contraction passage in which at least a part is contracted in a taper shape from a side of the vortex generation passage toward the side of the water discharge hole. The water feeding passage and the water/hot water collision part are integrally formed by a first member A, and a contraction passage of the water discharge hole passage is formed of a second member B capable of being separated from the first member.SELECTED DRAWING: Figure 5
