摘要： An object is to provide a water discharge device in which a water sprinkling member having water discharge ports can simultaneously achieve both good rotation start-up ability and good rotation stability. A water discharge device FC is configured in such a manner that the center of gravity of a rotor constituted of a tubular body 20 and a head 40 (the water sprinkling member) is positioned near an opening 4 which is located near the center of swing at which a central axis C1 of the tubular body 20 tilted by swinging revolution and a central axis C2 of an inflow chamber 3 intersect in a state where any water is not supplied to a buffer chamber 43 of the head 40, whereas the center of gravity of the rotor is moved to a head 40 side in a state where the water is supplied to the buffer chamber 43 of the head 40.

摘要： Provided is a shower apparatus which can stably supply bubbly water through all nozzle holes and can cause water droplets of large, uniform size to land continuously on the user so as to allow the user to enjoy a shower with a voluminous feel as if the user were being showered by large drops of rain. The shower apparatus F1 includes a water supply unit 21, a throttle unit 22 adapted to eject passing water downstream, an aeration unit 23 adapted to produce bubbly water by aerating the water ejected through the throttle unit 22, and a nozzle unit 24 provided with a plurality of nozzle holes 243 used to discharge the bubbly water, wherein the throttle unit 22 has a flat-shaped throttle channel 221 and water ejected through the throttle channel 221 plunges into an air-liquid interface BW3 as a sheet-like stream WF, thereby producing bubbly water, which is then discharged through the nozzle hole 243.

摘要： PROBLEM TO BE SOLVED: To provide a shower device which makes one enjoy such shower of massive feeling like being exposed to rain of large drops and stably discharge water through all of water spray openings. SOLUTION: The shower device F2 includes a water feed part 31, a throttle part 32 installed downstream of the water feed part and for spraying passing water to the downstream side, an air-mixing part 33 in which an opening 331 for mixing air in water sprayed through the throttle part, and forming cellular-mixed water is formed, and a water spray part 34 in which a plurality of water spray openings 343 for discharging the cellular mixing water are formed, and includes, a deceleration means for having a cross section change means to form so that it may become narrow by the throttle part side by making a cross section which intersects perpendicularly with a jet direction of water sprayed from a throttle part in an air mixing part vary in a direction along the surface in which the water spray hole is formed in the water spray part, and a speed dispersion means for standardizing velocity distribution generated by the deceleration means.

摘要： PROBLEM TO BE SOLVED: To provide a shower device capable of continuously landing droplets granulated to have large uniform diameter by supplying water mixed with bubbles uniform as possible on users to give massive feeling shower so as to take large drops of rain. SOLUTION: The shower device F2 is equipped with: a water supply unit 31; a constriction unit 32 for jetting passed water to the downstream side; an air mixing unit 33 for making a bubble containing water by mixing the water jetted through the constriction part 32 with air; and a water spray part 34 having a plurality of the spray holes 343 formed to discharge the bubble containing water. The shower device is configured such that the virtual line of the sprayed water which extends jetting direction of water sprayed from the constriction part 32 reaches the position where the water spray holes 343 are formed without interference from the inner walls which form the air-mixing unit 33 and the water-spraying unit 34. An eddy flow suppressing means for suppressing the eddy flow produced in the water spray part 34 by the water entering into the air-liquid interface is provided. COPYRIGHT: (C)2010,JPO&INPIT
