Definitions

  • the present invention relates to an improvement in a water delivery head capable of being used in whirlpool bath-tubs or small whirlpool swimming pools so as to deliver a mixture of water and air under pressure.
  • Water delivery heads for whirlpool baths are already known to substantially comprise a manifold-like body adapted to receive water under pressure and provided with at least an air suction opening, said air being taken in by Venturi effect and then substantially emulsified in the water under pressure for being finally delivered as an air-water mixture into the bath tub or pool through an adjustable nozzle that is supported in a swiveling manner by the manifold body.
  • the swiveling nozzle has a substantially spherical outer surface cooperating with a corresponding supporting seat provided in the manifold body.
  • the swiveling nozzle has a quite large surface area making friction with the manifold body and, therefore, making it difficult for the swiveling nozzle to be adjusted conveniently.
  • this problem is undesirably worsened by the thermal expansion events which the various component parts undergo periodically, as well as by scale formation and/or foreign-matter and dirt build-up that may eventually occur on said component parts.
  • it may well occur that adjusting the swiveling nozzle will eventually prove unacceptably inconvenient and difficult to perform with the desired accuracy.
  • the adjustment of the flow rate of the water and air jet issued by the nozzle is usually performed by means of a central pin which is ajustable by being screwed up and down so as to be displaced axially with respect to a corresponding conical seat provided on the nozzle or, anyway, on the delivery head. It ensues that the afore mentioned scale formation and buildup can eventually make it impossible to adequately shut off the swiveling nozzle and, as a consequence, the delivery nozzle.
  • a possibility to fully shut off the swiveling nozzle is quite desirable when the general operation of the whirlpool bath-tub is to be adapted to comply to particular needs, and also to prevent foreign matters from building up, encrusting and/or fouling the delivery head and the conduits associated therewith when the bath-tub is used to other purposes than whirlpool bathing. It will be easily appreciated that the latter is a problem that is particularly felt in cases such as those involving whirlpool bath-tubs installed in hotel rooms and the like.
  • DE-U-8 812 993 discloses a delivery head of the above-mentioned type in which the outer surface of the swiveling nozzle cooperating with a support seat is substantially semispherical, thereby correspondingly rendering orientation of the swiveling nozzle more convenient.
  • This solution substantially suffers from the same drawbacks described above with regard to the impossibility to adequately shut off the delivery nozzle.
  • the adjustment of the flow rate of the water and air jet issued by the nozzle is in fact performed, undesirably using a special tool, by screwing up and down an annular element supporting the swiveling nozzle, which is axially displaced accordingly with respect to a fixed air supply nozzle, thereby adjusting the flow rate.
  • scale formation and buildup can make it impossible to adequately shut off the swivelling nozzle.
  • the delivery head substantially comprises a manifold body 4 provided with at least an inlet orifice 5, through which it is adapted to receive water under pressure, as well as with at least an air suction orifice 6 (there are two of them in the embodiment described here by way of example), through which air can be taken into the manifold body 4.
  • the latter can be installed on the wall 18 of a whirlpool bath-tub, in correspondence of an appropriately provided hole, and preferably under interposition of at least a sealing gasket 20 therebetween, by means of a front ring nut 19 screwed in on the front inner surface of the manifold body 4; in a per sè known manner, said ring nut 19 may be covered with a ring 11 to essentially aesthetical purposes.
  • the delivery head is further provided frontally with an outlet nozzle 7 having a tapered inner lead-in opening 9 and formed axially on a substantially semispherical hollow body 8, preferably integral therewith.
  • Said hollow body 8 is kept in an axial position inside the manifold body 4 by means of a supporting annular element 10 which is substantially curvilinear in its cross-section, is arranged between the two elements 4 and 8, and is in turn fixed inside the manifold body 4 by means of a rear threaded portion 12 that is screwed down into a corresponding threaded portion provided inside the manifold body 4.
  • the outer surface of the semispherical body 8 co-operates slidably with said element 10 only in correspondence of an inner annular rib 13 thereof, which is provided in a front position and in relation to which said body 8 can be tilted and/or swiveled to adjust the nozzle 7.
  • said semispherical body 8 is provided on its rear side with a flexible discoidal wall 14, whose peripheral edge 15 has preferably a stepped shape so as to be able to engagingly mate with the circumferential edge of the body 8, which it is rotatably integral with (in a per sè known way, not shown here).
  • both said discoidal wall 14 and 17 are concentric and adjacent to said discoidal wall 14, but angularly integral with the manifold body 4 (in a per sè known way, not shown here).
  • the flexibility of both said discoidal walls 14 and 17 is increased owing to the fact that they comprise a plurality of respective ports 21, 22 which are substantially identical to each other and are formed on their surface, regularly spaced in a concentric circle.
  • both said discoidal walls 14 and 17 are in a preferred way slightly arcuated towards the rear portion of the delivery head.
  • the ports 21 surround an axial portion 23, which is preferably formed integrally therewith, protrudes frontally and defines an axial passage.
  • said axial passage extends from the wall 14 with a first flared axial portion 24 and a second cylindrical axial portion 25; furthermore, the front end of the axial portion 23 enters partially, in a loose way, the lead-in opening 9 of the nozzle 7.
  • the discoidal wall 17 has a central hole having a diameter which is at least equal to the largest diameter of the flared passage portion 24, against the inner surface of which abuts the preferably rounded-off front end portion 27 of a concentric pin 26 that extends from the rear wall of the manifold body 4.
  • said pin 26 has a diameter size lying between the diameter of said cylindrical passage portion 25 and the largest diameter of said flared passage portion 24, so that the discoidal walls 14 and 17, along with the semispherical body 8 and the nozzle 7, can be caused to swivel to a very wide extent with respect to the pin 26 having a negligibly small friction surface.
  • the dimensions of the various component parts can be easily calculated so as to cause said end portion 27 of the pin 26 to keep the various component parts pressed into a mutual axial engagement, as mentioned above, and, in particular, said discoidal walls 14 and 17 to undergo a slight elastic deformation axially (towards the front portion).
  • an elastic thrust turns out to be particularly advantageous, since it inherently prevents scaling and other foreign matters, that may possibly get into the delivery head, to settle down and build-up in correspondence of the pivoting point 27 of the nozzle 7.
  • the pin 26 is provided with an axial through-hole 28 that communicates with the air intake orifices 6 in correspondence of a chamber 29.
  • This chamber is defined by a seat 30, which is formed on the rear wall of the manifold body 4, and an enlarged rear end 31 of the pin 26 which joins sealingly with said seat 30.
  • the air being so taken in forms a mixture with the water under pressure and this mixture is then ejected frontally by the nozzle 7.
  • the flow rate of the jet produced by the nozzle 7 can be conveniently adjusted to a high degree of accuracy by rotating the same nozzle (which may to this purpose be provided externally with appropriate impressions 32, as shown in Figure 1), so as to vary in this way the relative angular position of the ports 21, 22 in the discoidal walls 14, 17 from a fully-open to a fully-closed condition of the cross-section of the passage provided for the water under pressure.
  • said cross-section of the passage for the water under pressure is shown to reflect a condition in which it is half-open.
  • such a safety provision may be further enhanced in its effectiveness by providing a check valve means in correspondence of the passage defined between the lead-in opening 9 of the nozzle 7 and said axial portion 23.
  • said check valve means consists of a flexible diaphragm 33 having the shape of a ring, whose rear end is forcedly fitted around the axial portion 23, and whose front end is flared as shown in Figure 2 so as to elastically rest against the lead-in opening 9, thereby shutting it, only when a backflow of water towards the inner side of the semispherical body 8 occurs. Even this semispherical body 8 is therefore effectively and reliably protected against any possible backflow of contaminated water.
  • a similar check valve means is also provided in the hole 28 of the pin 26, for instance in correspondence of the chamber 29.
  • a valve means is preferably constituted by a flexible diaphragm 34 that is adapted to only close the air passage cross-section in the occurrence of a possible backflow of water from the nozzle 7 towards the orifices 6, through the passages 25 and 28.
