HYDROMASSAGE JET. IT INCLUDES A CYLINDRICAL BODY 11 INCLUDING AN AXIAL PASSAGE IN WHICH IS FORMED A VENTURI TUBE OUTLET SECTION 14, AN AXIAL AIR INLET PARALLEL TO THE VENTURI TUBE SECTION AND A TRANSVERSAL WATER SUPPLY IN RELATION TO THE AXIS OF THE CYLINDRICAL BODY, AND UPSTREAM OF THE VENTURI SECTION, SO THAT IT CAN BE FITTED DIRECTLY TRANSVERSALLY IN A PRESSURIZED WATER SUPPLY DUCT.

Description

The present invention relates to a nozzle

  hydromassage, in particular of the type directly applicable to the pipe for supplying water under pressure. Hydromassage facilities based on the principle of using a stream of water mixed with air have been known for many years. In order to bring the stream of water and to mix it with air, we know and use sprinklers permanently attached to the walls of the bathtub or the basin in which the body of the person to undergo

the hydromassage is immersed.

  These nozzles must be connected to the pipe carrying pressurized water and an air outlet, so that in the case of baths and installations with a number of sprinklers the plumbing installation becomes

complicated and expensive.

  The main subject of the invention is a nozzle

  advanced type of hydromassage, allowing a simpli-

  the plumbing system and more flexible

  in the layout and programming of the hydromassage jets. The subject of the invention is also a nozzle which is smaller in size than the jets known conventionally while retaining the same operating qualities. These objectives, as well as other objectives, are achieved by means of the hydromassage nozzle according to the invention, characterized in that it comprises a body for supplying water and for mixing air and a connection that can be connected. said body and connected to a source of depression, said body having a venturi tube section and being provided with water inlet openings in its side wall;

  so that the mounting of the nozzle transversely

  port to the pressurized water supply pipe causes a transverse arrangement of said openings relative to

the flow of water.

  According to a first embodiment of the nozzle

2 2567750

  according to the invention, said coupling comprises a feed pipe

  of air at the choked section of the venturi where the air is mixed.

  According to a variant of the nozzle according to the invention, the air is brought to the outlet of the venturi tube section, the mixture thus taking place downstream thereof. The characteristics and advantages of the invention

  will emerge more clearly from the detailed description

  which will follow examples of embodiment shown in the accompanying drawing of which: Figure 1 is an axial section of the nozzle according to the invention; Figure 2 is a partial section showing the nozzle mounted on a pipe for supplying water under pressure; Figure 3 and Figure 4 are sections showing the two components of the nozzle of Figure 1; Figure 5 and Figure 6 schematically represent

  lines XIII-XIII and XIV-XIV of Figure 12.

  Referring to Figures 1, 3 and 4, the nozzle

  according to the invention, generally designated by the numerical reference

  10, comprises a body 11 and a suction connection

of air 12.

  The body comprises a substantially cylindrical block traversed axially by a conduit 13 comprising different sections. More particularly, the duct 13 comprises a front outlet section 14, having the shape of a venturi tube,

  an intermediate input section 15 in the transverse direction

  dirty water and an upstream section 16 in which is housed

the air intake connection 12.

  As clearly shown in FIG. 4, the connector 12 comprises a flanged portion 17 housed in section 16 and

  a conduit 18 aligned axially with the conduit 13 and terminating

  at a short distance from the mouth of the

  venturi, after having gone through all the section 15.

  At the level of section 15, the body

a water inlet opening 19.

  FIG. 2 specifically shows the fitting of the nozzle 10 in a pipe 20 for supplying water under pressure

in the direction of the arrow 21.

  Specifically, the nozzle 10 is mounted transversely

  relative to the axis of the pipe 20, in a calibrated hole in the wall opposite said pipe, so that the outlet section burst into the bathtub

  hydromassage which has been shown the wall 22.

  To fix the nozzle to the bath, the front part of the nozzle, that is to say the cylindrical block forming the body 11, is threaded as indicated by the reference 23, and this thread receives a profiled locking nut 24 associate

a seal 27.

  An air inlet or suction pipe 25 is connected, via a suitable branch, to section 16 of the nozzle and specifically to the conduit 18 of the nozzle.

fitting 12.

  The present description clearly shows how

  the invention makes it possible to adapt the location of the nozzle on the basis of the presence given and possibly pre-existing

plumbing piping.

  In addition, the nozzle according to the invention is smaller than the previously known nozzles, without

  this is to the detriment of its operation and its reliability.

  In particular, it is possible to realize,

  with the nozzles according to the invention, arrangements of hydro-

  massage such as those shown in Figures 5 and 6; in the first figure, the pipes 20 and 25 pass under the

  bath 26, so that the jets 10 discharge a neck

  rant massage the bottom of the tub 26.

  In the arrangements of Figure 6, the nozzles and hoses 20 and 25 are positioned laterally by

compared to the bathtub.

  The nozzle according to the invention makes it possible to easily program the operation of each nozzle, on the basis of

  hydromassage cycle and specifications.

  The nozzle shown in FIG. 7 comprises a body 32 comprising an axial duct comprising sections of different diameters and, more specifically, the inlet or fitting section 31, the outlet section 33 shaped as a venturi tube, and an intermediate section 34. inserted in the air intake connection 35. This connection has a shape of elbow, so that its downstream end 36 is aligned with the axis of the section 33 formed in venturi tube, while the upstream end comprises a flange 37 to be housed in a chamber 38 communicating

  with an air intake duct 39.

  The flange 37 and, by auite, the connection 35, are held in position by a plug 40 and the spring

of compression 41.

  Referring now to FIGS. 8 to 14, there is shown another embodiment of the nozzle according to the invention, which differs from those illustrated in FIGS.

  previous modes of execution by the fact that the air is

  changed to water downstream of said section, before the actual exit, instead of being within the section

venturi tube.

  In FIG. 8, reference numeral 120 denotes the water supply duct directed in the direction of arrow 121, so that in this case the nozzle is

  also mounted transversely to the conduit 120.

  The nozzle comprises a body 111 of generally cylindrical shape

  in which are mounted a front end connection, a venturi tube section, and a rear terminal connection

52 air inlet.

  The connector 52 is mounted on a suitable hole in the wall of the conduit 120 and is shown in greater detail in FIGS. 12, 13 and 14. More specifically, it includes a manifold 53 for the intake of air and three small ones. tubes that join seats in holes

  corresponding in the venturi tube section 51.

  Inside the body 111 is formed an annular chamber 55 into which the conduits 54 leading

  air at the inlet of the outlet fitting 50.

  As shown in FIGS. 10 and 11, the outlet fitting 50 is substantially conical, with the exception of a slight terminal counter-flare, and is attached within the

  111 by a thread 56 or a similar fastening means.

  The section of venturi tube 51 (shown in FIG. 9) is mounted, for its part, inside the body.

  111 by means of a thread 57 or by a functional means-

  equivalent, and protrudes towards the mouth

of the outlet fitting 50.

  As clearly shown in Figure 8, the mounting of the body 111 in a hole of the pipe 120 diametrically opposed to where the rear connector 52 is mounted leaves a space 119 through which the water, which flows into the conduit 120 under the appropriate pressure, enters the venturi tube section in the same way as for the nozzles shown in the previous figures, except that, in this case, air mixing takes place, not in the venturi tube section,

but downstream of it.

  It is clear that, in this case also, one of the essential advantages of the present invention, namely the direct mounting on the water supply duct, involving simplifications of structure and important assembly, is retained. The present invention has been described for a

  preferred execution, but it goes without saying that one can

  valences, without departing from the scope of the invention, and that

  each characteristic must be considered both indi-

  vidually and in combination with others.
