Definitions

  • the present invention relates to an improved hydromassage nozzle.
  • hydromassage consists of striking the user's body immersed in a tub or pool with a stream of water under pressure mixed with air delivered by one or more nozzles mounted in the walls of the tub or pool.
  • the water while passing through a section shaped like a venturi tube, causes negative pressure which in turn causes suction of air wihich mixes intimately with the water.
  • the nozzles of known type are also equipped with systems which make them adjustable although within a rather limited angle, in such a manner as to direct the stream with the desired inclination onto the user's body.
  • a first problem connected with the nozzles of known type is the problem of regulation, specifically of shutting off delivery of the stream from one nozzle, leaving in operation the other nozzles connected in the same water or air system. Indeed, when the water supply to a nozzle is completely closed there is often suction of water from the interior of the tub through the air suction duct of the nozzle in question.
  • nozzles of known type Another problem presented by nozzles of known type is that of easy disassembly for access to the internal parts for cleaning, maintenance and/or repair of failures.
  • the principal object of the present invention is to resolve the problems and drawbacks mentioned briefly above.
  • the present invention provides a nozzle for delivery of a stream of water under pressure mixed with air for hydromassage of the type comprising an adjustable body having a central passage shaped like a venturi tube on whose axis is arranged an air suction passage while water under pressure enters transversely said central duct upstream from the inlet of said venturi tube so that the passage of the water under pressure through the constriction of the venturi tube causes suction of air which mixes intimately with the water in said venturi tube, the adjustable body being furthermore housed in an adjustable manner around its own axis in a substantially cylindrical casing open at both ends and fixed to the wall of the tub or pool in such a manner that the end turned toward the interior of the tub is seated at the outlet of the venturi tube while the other end puts said air suction passage in communication with an air suction duct, there being made in said cylindrical casing at least one opening for connection with a duct for supply of water under pressure, characterized in that said air suction passage consists
  • said casing for housing said adjustable body and the flange which secures the nozzle to the wall of the tub or pool has a flared portion inclined toward the interior of the tub for unaided drainage of said nozzle.
  • the nozzle according to the present invention comprises an adjustable body 10 which is seated in a casing 11 on which are provided in the same piece the unions 12 and 13, respectively with the duct for water under pressure and with the air suction duct.
  • the casing 11 is fixed to the wall 14 of the tub or pool (not shown) by means of a ring-nut 15 which engages by screwing an internal threaded part of the casing 11.
  • an anular part 16 which engages by screwing a threaded portion 17 of said casing 11.
  • the pads 18 preferaably of rubber or some other flexible material are integral with the anular part 16 for the purpose set forth below.
  • a nozzle cover 20 is in turn fixed to the anular part 16 with the screws 21 to mask aesthetically the flange 15 which fixes the nozzle.
  • support pads 22 for the adjustable body 10 made of rubber or some other flexible material for the purpose set forth below.
  • a duct 23 shaped with a constricted section like a venturi tube.
  • a sleeve 25 which forms a seat 26 in which is housed by threading a base 27 which bears as part of the same piece a duct 28 for air suction.
  • the duct 28 extends in the position illustrated in Figs. 1 and 3 to close the constricted section 24 of the venturi tube, the watertightness of said closure being aided by an anular gasket 29.
  • the duct 28 communicates with the air suction duct 13 through a hole 30 closed by a valve 31 which opens when there is negative pressure in the constricted section 24 of the venturi tube, shutting off air suction when there is no water under pressure passing through the venturi tube, i.e. in the conditions of Fig. 1.
  • Fig. 1 illustrates a valve 31 of the double- disk type while Fig. 3 illustrates a disk-type check valve with compression spring. It is clear that these arrangements are only illustrative and not limitative.
  • apertures or windows 32 through which the interior of said base can communicate with the duct 12 which supplies water under pressure.
  • the base 27 and the sleeve 25 both have rounded outer surfaces so that they can operate together with the pads 18 and 22, adjusting themselves with respect to the axis of the venturi tube with a maximum inclination of 15° and over the entire arc of 360°.
  • Fig. 1 also shows that the internal surface 19 of the casing 11 is inclined toward the outlet of the nozzle so that water cannot stagnate therin when the nozzle is not delivering the stream of water mixed with air.
  • the flange 15 also has a truncated-cone or tapered inner surface such as to comprise the continuation of the surface 19 and offer no obstructions to natural discharge or drainage of water.
  • Figs. 4 and 5 illustrate an auxiliary part 33 having a base 34 which couples with the outlet of the duct 23 and a tapered tip 35 with an outlet slot 36 which creates a fan-shaped stream which can cover a broader area to be subjected to hydromassage.
