Definitions

  • the present invention relates to an orientable outlet fitting for hydromassage plants, to be used in a bath tub, of the type which can be secured to a wall of the tub, said fitting comprising a first nozzle for the inlet of a water jet surrounding a second coaxial nozzle for the inlet of the air within the aforesaid water jet.
  • Hydromassage plants are known since long time , permitting jets of water under pressure mixed with air , as delivered by one or more fittings fixed or incorporated in the walls of a tub or swimpool, to strike the body of the user immersed in the said tub or swimpool.
  • the water passed through a nozzle having a cross section shaped as Venturi pipe, causes a depression to be generated , inducing the air suction from a coaxial internal nozzle , the air being intimately admixed with the water in form of small bubbles dragged together with the water jet.
  • the known fittings are provided with systems by which they are, although limitedly, orientable as desired so as to direct the jet according to a desired direction.
  • a first problem raised by the known fittings is that of the adjustment and more particularly of the closing of a water jet outcoming from a fitting, while other fittings are maintained in operation, which owing to their section shaped as a Venturi pipe may induce a depression within the air duct such as to cause a water return from the tub through the internal nozzle of the out of operation fitting.
  • Another problem which is too connected to the known fittings is that of the retention of a certain amount of water within the body of the fitting, since , this water being often the same soapy water contained within the bath tub subjected to a recirculation, said retention might induce hygienic problems.
  • a further drawback to be faced is the return of water from the tub within the recirculation circuit for the hydromassage through the same fittings during a normal use of the bath tub only for deterging purposes, whereby solutions of soaps or detergents containing surface active substances may lead to an excessive forming of foam when the hydromassage operation is started again, without take it into account the hygienic drawbacks as above mentioned with relation to the retention of such solutions within the said recirculation circuit.
  • the Italian Patent Application No. 22165 A/85 filed on September 17, 1985 discloses a solution by which the water and air delivery openings of a fitting mounted to a bath tub are closed , said closure being controlled by a valve normally closed by a spring which, being pushed outwardly from the recirculation water pressure, causes simultaneously a passage for a jet of said water and for the air to be admixed with said jet to be opened, the circulation water being admitted owing to the opening of a hydraulically controlled valve.
  • the present invention aims to eliminate these drawbacks by providing an outlet fitting having an outer casing or shell, which can be secured to a tub wall,containing a water nozzle surrounding a coaxial nozzle for the air introduction, characterized by the features of the characterising portion of claim 1.
  • Said water nozzle is slidably connected to a sleeve of a joint element which is substantially spherical, consisting of two hemispherical shells, comprising two cavities, coaxial to each other and separated, the outer most of which is into comunication at one and with a chamber and a water duct and the other end with said water nozzle movable outwardly and the inner most is into comunication at one end with an air chamber and at the other end forms said coaxial jet, for the introduction of air internally with respect to said water nozzle, said upwardly movable water nozzle, being provided with a planar relief to which the water pressure is applied and against the action of a spring to displace it upwardly in order to open a passage between said outer nozzle and said internal nozzle.
  • said spherical joint abuts against a seat provided with a gasket ensuring the tight sealing between the water chamber and the air chamber.
  • the outer nozzle for the water is shaped as a Venturi pipe with the area of minimum section or throat occupying the position around the outlet edge of said internal nozzle when the outer nozzle is moved outwardly by the water to cause therein a depression adapted to open the said check valve and air in form of bubbles is entered within the water jet.
  • a hydromassage fitting 10 consists of a shell 12, having essentially cylindrically cavities fixed to a wall 14 of a bath tub by means of a threaded locking ring 16 which is screwed within a corresponding threaded seat of said shell 12, and is provided with a covering 18 for the connection to the said tub wall 14 fixed to said locking ring 16 by means such as screw 20 and 22 screwed on within suitable threaded holes in the same locking ring 16.
  • a jet generator assembly 24 comprises an outer nozzle 26 inserted into a substantially spherical joint formed by an essentially fore semispherical shell 28 fixed to a substantially rear semispherical shell 30 and housed within a rear chamber 32 of the said shell 12 wherein it is pushed by a threaded locking ring 34, having an internal edge thickened and rounded 36, against a bottom gasket 38 surround by a circular relief 40 placed onto the bottom of the rear chamber 32.
  • the outer nozzle 26 is guided by a sleeve 42 coming out of the fore semispherical shell 28 and is provided at the internal end with a planar relief 44 pushed by a spring 46 against the fore edge 48 of the rear semispherical shell 30 whereas and anular gasket 50 provides for the sealing between said nozzle 26 and said sleeve 42.
  • the rear semispherical shell 30 is provided cross-wise with a substantially cylindrical duct ending in the fore part with a nozzle 52, which is internal and coaxial with respect to the above mentioned outer nozzle 26 and defining a through cavity 54 closed at about the middle thereof by a check valve 56 consisting of a disk 58 maintained abutted against it sit by a spring 60.
  • Said through cavity 54 is indirect comunication with a chamber 62 connected by a tub (not shown) with an external air suction inlet.
  • the periphery of the same rear semispherical shell 30 is provided with slit or cuts 64 by which a cavity 66 thereof sorrounding said internal nozzle 52 is put into comunication with the rear chamber 32 of the shell 12 which, in turn, is connected to a duct 68 serving to bring water, coming from a recirculation pump, within the shell 12 of the hydromassage fitting.
  • the outer nozzle 26 is crossed by a duct having the shape of a Venturi pipe with a first converging area 70 followed by a throat area 72 and then by a divergent area 74.
  • the operation of the present invention is as follows: when the fitting 10 is out of the operation the outer nozzle 26 is maintained in the withdrawn position by the pressure of the spring 46 pushing against the planar relief 44 whereby a closure between the outer nozzle 26 and coaxial internal nozzle 52 is ensured.
  • valve 56 within the nozzle 52 is maintained in the closed condition by the action of the spring 60 keeping the disk 58 adherent to the lower seat whereby possible water present in the tub is prevented from returning within the air inlet circuit connected to the chamber 62.
  • the assembly of the two semispherical shells 28 and 30 present in the chamber 32 forms a spherical joint permitting an arbitrary orientation, although limited, of the generating assembly 24 to direct the ject according to a desired direction.
  • the internal round edge 36 permit a relatively free sliding of the surface of the fore semispherical shell 28 whereas the bottom gasket 38, although permitting a relatively free sliding motion of the surface of the rear semispherical shell 30, prevents water from passing from the rear chamber 32 to the air chamber 62.
  • valve 56 might be a valve with elastic membrane which can be raised by the air streem entering from the chamber 62 and which can be collapsed under the action of the water contained within the tub and the gasket 50 might be multiple instead of being only one as represented in the figures.
