Definitions

  • the invention relates to an outlet nozzle for the outlet valve of a whirlpool tub with a water supply duct and an air supply duct, in which the water flow is mixed with the air flow due to the action of an injector.
  • the object of the present invention is to improve such an outlet nozzle with regard to the hydro-pneumatic massage effect and to make it more pleasant. Furthermore, the outlet nozzle should be contaminated by impurities contained in the water of the whirlpool, such as hair, residues of personal care products and the like. largely avoided and cleaning of the outlet nozzle can be facilitated.
  • the water supply channel merges into a radially outwardly leading annular outlet channel, which is formed between a plate-shaped distribution body and the valve body of the outlet valve, and that the preferably circularly shaped air supply channel in a radially outward to the Outlet channel or with this radially externally merged annular intermediate space between the plate-shaped distributor body and the valve body or the valve housing or tub wall opens.
  • a kind of ring-shaped Venturi effect is achieved with the solution according to the invention, since the air supplied is sucked in over the entire circumference of the nozzle body and mixed with the water flow.
  • the water-air mixture is directed on all sides essentially parallel to the tub wall, preferably the tub floor, so that the jet does not impinge directly on the user, but instead fine bubbles rise from the intensive water-air mixture, which is directed essentially parallel to the tub wall, which leads to a pleasant hydro-pneumatic massage effect.
  • the water supply channel points axially and centrally to the inner surface of the plate-shaped distribution body and merges into the annular outlet channel, which is formed between the plate-shaped distribution body and an inner plate-shaped distribution body arranged underneath, and that the air supply channel into one Annular gap opens between the inner distribution body and the tub wall or the valve body or the valve housing.
  • the inventive arrangement of an outer and inner distribution body achieves a particularly high suction effect of the air supplied over the entire circumference of the nozzle body and at the same time increases the injector effect.
  • the air supply channel preferably forms an annular outlet slot surrounding the central water supply channel, which opens into the annular gap between the inner distribution body and the tub wall or valve body or valve housing. In this way, an air outlet that is as uniform as possible over the entire circumference of the nozzle body and thus a uniform water-air mixture is achieved.
  • the injector effect of the outlet nozzle according to the invention can be further improved in that a conical or -like projection points axially centrally from the inner surface of the outer distribution body in the direction of the water supply channel.
  • the water flow emerging axially from the water supply channel is thereby deflected radially uniformly and effectively in all directions, in order to exit the circular exit tread channel to exert suction on the air introduced into the annular gap below the inner distribution body.
  • the outer and inner distribution bodies are connected via radial ribs which subdivide the circular outlet channel into individual radial outlet channels.
  • the ribs therefore not only have a connection function, but also a guide function for the water flow directed outward in the annular outlet channel. They also support the even distribution of the water flow over the entire circumference.
  • the ribs can end at a distance in front of the outer edge of the outer distribution body and / or the inner distribution body in order to leave enough space for the water jet to emerge from the nozzle body.
  • the height of the annular outlet channel or the individual outlet channels separated therefrom decreases from radially inside to radially outside, so that the water jet in the outlet channel achieves the required outlet speed for the injector effect.
  • the inner surface of the outer distribution body can be inclined from radially inside to radially outside at a slight angle Trough wall to or run approximately parallel to this.
  • the outer surface of the inner distribution body apart from a central passage, runs obliquely from radially inside to radially outside at a slight angle toward the tub wall or approximately parallel to it .
  • a suitable uniform air supply at the outer edge of the nozzle body is obtained in that the inner surface of the inner distribution body preferably runs approximately parallel to the tub wall or only at a slight angle to it.
  • a special feature of the invention is also seen in the fact that the inner distribution body has a smaller diameter than the outer distribution body. As a result, the outer distribution body overhangs the inner one, so that the injector action, where radial water flow and radial air flow meet, can develop largely undisturbed by the tub content.
  • the injector effect can be further improved by rotating a bead-like elevation on the edge area of the outer surface of the inner distribution body (or on the edge area of the inner surface of the outer distribution body), which causes a narrowing of the annular outlet slot between the outer and inner distribution body.
  • the two distribution bodies are preferably made in one piece from plastic or rubber, including any ribs that may be provided. This not only facilitates manufacture and assembly, but also avoids impairment of sitting on the tub floor with the flatest possible construction, since plastic and rubber have low heat conduction coefficients and therefore do not feel "cold" and, on the other hand, can be designed so resiliently at least in their surface area that an impairment of the seating comfort does not occur in the tub floor equipped with the outlet nozzles according to the invention.
  • the already existing buoyancy forces that the human body experiences in water also contribute to this.
  • the inner distribution body prefferably be formed by an upper radial edge widening of the wall region of the valve body between the central water supply channel and the air supply channel surrounding it. Possibly.
  • the valve body, inner distribution body, radial ribs and outer distribution body can therefore be made in one piece.
  • valve body projects over the valve housing of the outlet valve with a peripheral flange and the annular gap for the air outlet is formed between the inner distribution body and the peripheral flange.
  • the surface of the peripheral flange of the valve body can drop radially outwards towards the tub wall, so that the outlet gap for the water-air mixture widens radially outwards in order to achieve a pleasant flow rate of the mixture.
  • the one-piece nozzle body consisting of the outer distribution body, the inner distribution body and the radial ribs connecting them, can be detachably held on the valve body, for example by a bayonet, screw, suction, plug-in or magnetic connection, or (as already mentioned) be integrally formed with the latter .
  • the water supply channel has radially arranged outlet openings in the area of the outlet channel.
  • the deflection of the axially supplied water already takes place within the feed channel, so that it can flow through the outlet channel evenly from all sides in order to exert a suction effect on the air introduced into the intermediate space.
  • valve body is in the region of the Outlet channel has an axial extension with an engagement groove for attaching the possibly made of flexible material distribution body.
  • a further improvement in the injector effect of the outlet nozzle according to the invention can be achieved in that the inner surface of the plate-shaped distribution body tilts obliquely towards the tub wall from the radially inside to the radially outside at a small angle, forming a radial outlet slot in the edge region of the outlet channel. This gives the water jet the necessary exit speed for a good injector effect.
  • the inner surface of the plate-shaped distribution body in the space adjoining the outlet channel can run away from the tub wall at a slight angle or approximately parallel to it.
  • the inner surface of the plate-shaped distribution body in the area of the transition between the outlet channel and the radially outward adjoining intermediate space with the opposite ones Parts of the outlet valve forms a venturi throat.

  • the piston or the pistons While in the open position of the piston or the pistons the piston surfaces with the inner surface of the distribution body form the outlet channel and the space adjoining it radially outwards, the piston or the pistons move with their surfaces essentially axially when the outlet nozzle is switched off the inner surface of the distribution body so that at least opposite areas of these surfaces ensure a liquid-tight seal, for example of the water supply channel and / or the air supply channel.
  • the at least one piston is expediently guided axially in the valve body or on the valve housing or on the tub wall for the axial stroke movement.
  • the air supply duct can also be advantageous for the air supply duct to be divided into radially arranged individual air supply ducts which are connected to bores extending axially in the piston.
