FOAMED WATER DISCHARGING DEVICE AND FOAMED WATER DISCHARGING UNIT
20180147584 · 2018-05-31 ·

A foamed water discharging device includes a water feeding hole, a water discharging hole, a water passage, a ventilation passage, and a foamed water generator. The water passage has a cylindrical inner circumferential surface extending from the water feeding hole to the water discharging hole. The ventilation passage takes in external air on the upstream side of the water passage. The foamed water generator causes water containing the external air to undergo a collision on the downstream side of the water passage so as to convert the water into foamed water. The foamed water generator includes flow dividing ribs along the inner circumferential surface of the water passage, which protrude radially toward the center of the water passage. On a top portion of each flow dividing rib, at least a pair of inclined surfaces are formed to divide, rightward and leftward, water inflowing from a water guiding passage through the water feeding hole.
