To provide a spout apparatus which is easily maintainable by a user even when, in a fluid device utilizing Karman vortices, scale adheres to the Karman vortex generating portion. A spout apparatus for discharging hot or cold water while causing it to reciprocally oscillate, having a spout apparatus body and an oscillating element; whereby the oscillating element has a water supply passage, a vortex generating passage, and a spout port passage; the spout port passage is formed of an elastically deformable soft member and is attached to the spout apparatus body so that a user can manipulate the spout port passage to deform it; and the vortex generating passage is formed of an elastically deformable soft member, and is integrally formed with the spout port passage so that deformations of the spout port passage can be transmitted to this vortex generating passage.

Spout apparatus

To provide a spout apparatus whereby expansion and deformation of the inner wall surface of the vortex generating portion such that a desired Karman vortex cannot be generated are prevented, even when the port portion is formed of an elastically deformable soft member. A spout apparatus for discharging hot or cold water with reciprocal motion, having a spout apparatus body and a vortex generating passage; whereby the oscillating element has a supply passage, a vortex generating passage, and a spout port passage, and the spout port passage is formed by an elastically deformable soft member, and is attached to the spout apparatus body so that a user can manipulate and deform the spout port passage, and the vortex generating passage is formed so as not to expand and deform even if internal pressure rises due to the supply of hot or cold water from the supply passage.

Spouting apparatus

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 includes a water supply unit, a throttle unit adapted to eject passing water downstream, an aeration unit adapted to produce bubbly water by aerating the water ejected through the throttle unit, and a nozzle unit provided with a plurality of nozzle holes used to discharge the bubbly water, wherein the throttle unit has a flat-shaped throttle channel and water ejected through the throttle channel plunges into an air-liquid interface as a sheet-like stream, thereby producing bubbly water, which is then discharged through the nozzle hole.

Shower apparatus

A shower apparatus Fincludes a water supply unit; a throttle unitinstalled downstream of the water supply unitand adapted to eject passing water downstream; an aeration unitprovided with an openingadapted to produce bubbly water by aerating the water ejected through the throttle unit; and a nozzle unitprovided with a plurality of nozzle holesadapted to discharge the bubbly water, wherein a virtual water ejection straight line obtained by extending an ejection direction of the water ejected through the throttle unitreaches a location where the nozzle holesare formed, without interfering with inner walls of the aeration unitand the nozzle unit

Provided is a shower apparatus which can stably produce and supply bubbly water to nozzle holes, causing finely divided water droplets of relatively large, uniform size to land continuously on a 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 includes a water supply unit, a throttle unit adapted to eject passing water downstream, an aeration unit adapted to produce bubbly water by aerating the water ejected through the throttle unit, and a nozzle unit provided with a plurality of nozzle holes used to discharge the bubbly water, wherein an ejection speed changing means is installed in the water supply unit to at least partially vary ejection speeds of the water ejected from respective throttle channels of the plurality of throttle channels of the throttle unit.

Providing a flush bowl capable of discharging a planar shower-like water discharge flow in a wide range while changing the water discharge trajectory is directed. The shower device according to an embodiment of the invention is a shower device including: a water discharger including a plurality of water discharge ports; a rotator including a channel at its center; a coupling section coupling the inside of the water discharger to the channel of the rotator; a receiving section receiving the rotator; a driving mechanism configured to rotate and revolve the rotator in the receiving section; and a decelerating section provided inside the water discharger. The plurality of water discharge ports is provided asymmetrically with respect to a central axis of the rotator, or discontinuously in a peripheral direction, the water discharger is configured to rotate and revolve by rotation and revolution of the rotator caused by the driving mechanism, the plurality of water discharge ports is configured to cause rotational trajectories of water discharged from the water discharge ports to undergo a periodic rotary motion associated with the rotation of the rotator, the decelerating section has an area larger than a cross-sectional area of the coupling section, and the water discharge ports have a smaller total cross-sectional area than the decelerating section so as to accelerate water decelerated by the decelerating section.

Shower device

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 bodyand a head(the water sprinkling member) is positioned near an openingwhich is located near the center of swing at which a central axis Cof the tubular bodytilted by swinging revolution and a central axis Cof an inflow chamberintersect in a state where any water is not supplied to a buffer chamberof the head, whereas the center of gravity of the rotor is moved to a headside in a state where the water is supplied to the buffer chamberof the head

Water discharge device

A shower bathing apparatus is described as including a seat and a first water discharger provided rearward and upward in relation to the seat. The first water discharger is configured to discharge water in a direction forward of the seat. A water discharge direction from the first water discharger and a positional relationship between the first water discharger and the seat may be adjustable so that the water discharged from the first water discharger is able to reach the seat or forward of the seat. The water discharged from the first water discharger may further flow from above a seat occupant's shoulder to the seat occupant's leg.

Shower bathing apparatus

A shower bathing apparatus includes: a concave seat; and a water discharger provided rearwardly and upwardly to the seat and configured to discharge water in a forward direction of the seat. A water discharge direction from the water discharger and positional relationship between the water discharger and the seat are adjusted so that at least part of the discharged water directly reaches the seat with no seat occupant seated on the seat.
