Definitions
- the present invention relates in general to a nozzle assembly for feeding water into the interior of the tub of a hydromassage bath, and in particular for feeding a mixture of water and air.
- Hydromassage baths are known to comprise a tub provided, on its walls, with nozzle assemblies fed by a system which draws water from the tub after its filling, and feeds it, under pressure, back into the tub via suitably shaped nozzles; either pressurized water alone or a mixture of water and air can be fed.
- the nozzle assemblies do not allow water to pass either into the nozzle assemblies themselves or into the pipes of said system, to prevent stagnation of water which, being mixed with substances removed form the user's skin and scum, could create moulds and bacteria which would be recirculated when effecting hydromassage, and also create blocking problems for the devices inside the nozzle assembly.
- said nozzle assemblies must also draw air from the external environment and mix it into the jet of pressurized water to enable the hydromassage to be effected with a mixture of air and water.
- nozzle assemblies of the above described type are shown in US-A-4 896 384 and EP-A-0 297 246 .
- nozzle assemblies are known presenting unidirectional valves arranged to prevent the water in the bath tub from flowing back into the nozzle interior. Being positioned along the flow direction of the pressurized water, they operate with a relatively high pressure drop as the resistance of the reaction spring of said valves has to be overcome, and moreover they are costly, and bulky to position in the interior of the nozzle assembly.
- An object of the present invention is to overcome the stated drawbacks within the framework of a simple and rational solution.
- Figures 1 and 2 show a nozzle assembly 1 to be fixed to a wall 31 of a tub 30 of the bath.
- Said nozzle assembly 1 comprises a casing consisting of a first tubular part 14 to be fixed in correspondence with a respective hole 32 provided in the wall 31 to feed into the tub 30 a respective water jet originating from the nozzle assembly 1, and a second part 16 to be housed as an exact fit within an inner cylindrical surface 15 of said first part 14.
- the casing 14, 16 comprises a first chamber 11, connected to a supply conduit 40 and a discharge conduit 42, and a second chamber 12, directly connected to a suction conduit 41 via a passage 18; said chambers 11 and 12 are separated from each other by a separation wall 21.
- the water supply conduit 40, the discharge conduit 42 and the suction conduit 41 are fixed to said casing 14, 16.
- Said parts 14 and 16 present suitable seats for gaskets 34, 35 and 36, used to prevent air seepage from the second chamber 12 and to prevent water seepage from the first chamber 11.
- the second part 16 presents an outer edge 141 bent rearward to fix it to the wall 31; in this respect, said part 16 is firstly inserted into the hole 32 until the edge 141 is brought into contact with the outer surface of the wall 31 then, after the first part 14 has been fitted onto the second part 16, a clamping nut 70 is screwed onto a thread 71 provided on that portion of the second part 16 distant from the bath tub 30, to lock the first part 14 to the wall 31.
- the first part 14 is sealed against water seepage from the tub 30 by the presence of a suitable annular seat 37 filled with silicone, and a gasket 33.
- the second part 16 is separated from the tub 30 by a cover 17, at the centre of which there is an ejection hole 13.
- the nozzle assembly 1 comprises a nozzle 20, positioned on the separation wall 21 and having a through channel 23 which connects the first chamber 11 to the second chamber 12 and possesses a mouth 22 projecting into the second chamber 12; said nozzle 20 produces a water jet with its exit directed towards the ejection hole 13.
- the nozzle assembly 1 also comprises, in the second chamber 12, a movable valving element 50 to open or vice versa close the ejection hole 13 and suitably operated by operating means 51.
- the valving element 50 is bounded by a front first wall 56 parallel to and adhering or nearly adhering to the ejection hole 13, and a rear second wall 57 opposite the front wall 56 and parallel to and adhering or nearly adhering to the projecting mouth 22 of the nozzle 20 when the valving element 50 moves into its closed position.
- the valving element 50 also comprises a through channel 55 internally disposed between the first wall 56 and the second wall 57 and shaped to enable, in combination with the nozzle 20, air to be drawn in from the second chamber 12 via suitable apertures 19, and to form a mixture of air and water.
- the through channel 55 presents an initial portion disposed in proximity to the nozzle 20, and having a cross-section greater than the cross-section of the channel 23 at the mouth 22; that part of this initial portion which extends radially from the projecting mouth 22 of the nozzle 20 defines said apertures 19.
- the channel 55 presents a cross-section which gradually converges to transform the energy due to the water pressure into kinetic energy to increase the water outflow velocity.
- the final portion of the channel 55 presents a constant cross-section, close to the cross-section of the ejection hole 13.
- Said operating means 51 comprise a blade 52 positioned in the first chamber 11, and rigidly fixed to a first portion of a rod 53, which is rotatably inserted through a hole 25 provided in the separation wall 21, and of which the second portion is rigidly fixed to the valving element 50.
- the rod 53 defines the axis of rotation of the valving element 50 which is perpendicular (or a small angle off perpendicular) to the plane of the ejection hole 13; as will be apparent hereinafter, this axis is positioned at a suitable distance from the barycentre of the valving element 50.
- the blade 52 is shaped with a profile presenting a concave surface to the water from the supply conduit 40, to increase the thrust of the water on the blade 52.
- the nozzle assembly 1 is connected to a further nozzle assembly, positioned downstream, by means of the discharge conduit 42, which is connected to the supply conduit 40 of said further nozzle assembly, said nozzle assembly 1 being connected to a preceding upstream nozzle assembly by means of its supply conduit 40, which is connected to the discharge conduit of said preceding nozzle assembly.
- a pump of the hydraulic system connected to the nozzle assemblies withdraws water from the tub 30 of the bath and feeds it under pressure to the supply conduit 40.
- the pressurized water enters the first chamber 11 to strike against the surface of the blade 52, to generate about the axis of the rod 53 a first twisting movement able to position the valving element 50 in a first open position.
- Said open position (see Figure 3 and Figure 4B ) is such that the channel 55 becomes positioned coaxial to the nozzle 20, through which the pressurized water jet originates, and to the ejection hole 13, to enable a mixture of air and water to be ejected towards the tub 30 of the bath.
- said valving element 50 moves into the closed position, with its front wall 56 adhering to the ejection hole 13 to close it, and with its rear wall 57 adhering to and closing the projecting mouth 22 of the nozzle 20 (see Figure 4A ); by virtue of this, the water present in the tub is prevented from penetrating into the second chamber 12, or at least any organic substances are prevented from being able to flow back into the second chamber and from there to the first chamber 11, creating moulds and bacteria and possible blockage.
- Said closed position is achieved because of the fact that as the barycentre of the valving element 50 is displaced from its axis of rotation (axis of the rod 53), the weight of the valving element 50 creates a second twisting moment about the axis of the rod 53, to return the valving element 50 into its normal closed position, where it adheres to the cover 17 and to the nozzle 20.
- Elastic means in particular a torsion spring 54, can be added to return the valving element 50 into its closed position when water flow is lacking.
- this either has a totally or partly ferromagnetic body, or presents two counter-magnets 26a and 27a having opposite polarities to the corresponding magnets 26 and respectively 27 and positioned on opposite sides of the valving element 50; the magnets and counter-magnets are in geometrical relationship to each other such that when the valving element is in its closed position ( Figure 4A ), the magnet 26 is in contact or near contact with the counter-magnet 26a, whereas when the valving element is in its open position ( Figure 4B ), the second magnet 27 is in contact or near contact with the counter-magnet 27a.
- pairs of magnets and counter-magnets 26-26a and 27-27a serve to secure the valving element with a certain force, maintaining it in either its closed or open position.
- the force of the pressurized water which on entering the first chamber 11 strikes the blade 52 is able to overcome the force of attraction between the magnet 26 and counter-magnet 26a, whereas the thrust of the spring 54 and the weight of the valving element 50 is able to overcome the force of attraction between the magnet 27 and counter-magnet 27a when the thrust of the pressurized water against the blade 52 ceases.
- the rod 53 possesses a threaded intermediate portion which is helically engaged with the likewise threaded hole 25 in the wall 21; this engagement is such that when the valving element 50 is in its open position (as shown by the full lines in Figure 2A ), it lies at a distance (a few millimetres) from the hole 13; in contrast, when the valving element 50 rotates into its closed position (as shown by dashed lines in Figure 2A ), the engagement with the hole 25 causes it not only to rotate but also to translate, at least a little, towards the hole 13, until its front wall 56 adheres to it. Effective adhesion of the valving element against the hole 13 can hence be obtained, with consequent effective closure thereof.

Description
- The present invention relates in general to a nozzle assembly for feeding water into the interior of the tub of a hydromassage bath, and in particular for feeding a mixture of water and air.
- Hydromassage baths are known to comprise a tub provided, on its walls, with nozzle assemblies fed by a system which draws water from the tub after its filling, and feeds it, under pressure, back into the tub via suitably shaped nozzles; either pressurized water alone or a mixture of water and air can be fed. As the tub, even if provided with the hydromassage system, usually also serves for the normal part cleaning bath, it is important that when the hydromassage system is inactive the nozzle assemblies do not allow water to pass either into the nozzle assemblies themselves or into the pipes of said system, to prevent stagnation of water which, being mixed with substances removed form the user's skin and scum, could create moulds and bacteria which would be recirculated when effecting hydromassage, and also create blocking problems for the devices inside the nozzle assembly. Importantly, said nozzle assemblies must also draw air from the external environment and mix it into the jet of pressurized water to enable the hydromassage to be effected with a mixture of air and water.
- Known nozzle assemblies of the above described type are shown in
US-A-4 896 384 andEP-A-0 297 246 . Currently known nozzle assemblies able to satisfy the aforesaid requirements and functions are constructionally complex and costly; in particular, nozzle assemblies are known presenting unidirectional valves arranged to prevent the water in the bath tub from flowing back into the nozzle interior. Being positioned along the flow direction of the pressurized water, they operate with a relatively high pressure drop as the resistance of the reaction spring of said valves has to be overcome, and moreover they are costly, and bulky to position in the interior of the nozzle assembly. - An object of the present invention is to overcome the stated drawbacks within the framework of a simple and rational solution.
- These and other objects are attained bv the nozzle assembly of the present invention as characterised in the claims.
- The characteristics and constructional merits of the invention will be apparent from the ensuing detailed description given with reference to the figures of the accompanying drawings, which show a particular preferred embodiment thereof by way of non-limiting example.

Figure 3 is a section on the plane III-III offigure 2 . -
Figure 4A andFigure 4B are a front view of the invention offigure 1 , in two different operative configurations. -
Figures 1 and2 show anozzle assembly 1 to be fixed to awall 31 of atub 30 of the bath. - Said
nozzle assembly 1 comprises a casing consisting of a firsttubular part 14 to be fixed in correspondence with arespective hole 32 provided in thewall 31 to feed into the tub 30 a respective water jet originating from thenozzle assembly 1, and asecond part 16 to be housed as an exact fit within an innercylindrical surface 15 of saidfirst part 14. - The
casing first chamber 11, connected to asupply conduit 40 and adischarge conduit 42, and asecond chamber 12, directly connected to asuction conduit 41 via apassage 18; saidchambers separation wall 21. Thewater supply conduit 40, thedischarge conduit 42 and thesuction conduit 41 are fixed to saidcasing parts gaskets second chamber 12 and to prevent water seepage from thefirst chamber 11. - The
second part 16 presents anouter edge 141 bent rearward to fix it to thewall 31; in this respect, saidpart 16 is firstly inserted into thehole 32 until theedge 141 is brought into contact with the outer surface of thewall 31 then, after thefirst part 14 has been fitted onto thesecond part 16, aclamping nut 70 is screwed onto athread 71 provided on that portion of thesecond part 16 distant from thebath tub 30, to lock thefirst part 14 to thewall 31. Thefirst part 14 is sealed against water seepage from thetub 30 by the presence of a suitableannular seat 37 filled with silicone, and agasket 33. Thesecond part 16 is separated from thetub 30 by acover 17, at the centre of which there is anejection hole 13. - The
nozzle assembly 1 comprises anozzle 20, positioned on theseparation wall 21 and having a throughchannel 23 which connects thefirst chamber 11 to thesecond chamber 12 and possesses amouth 22 projecting into thesecond chamber 12; saidnozzle 20 produces a water jet with its exit directed towards theejection hole 13. - The
nozzle assembly 1 also comprises, in thesecond chamber 12, amovable valving element 50 to open or vice versa close theejection hole 13 and suitably operated byoperating means 51. Thevalving element 50 is bounded by a frontfirst wall 56 parallel to and adhering or nearly adhering to theejection hole 13, and a rearsecond wall 57 opposite thefront wall 56 and parallel to and adhering or nearly adhering to the projectingmouth 22 of thenozzle 20 when thevalving element 50 moves into its closed position. Thevalving element 50 also comprises a throughchannel 55 internally disposed between thefirst wall 56 and thesecond wall 57 and shaped to enable, in combination with thenozzle 20, air to be drawn in from thesecond chamber 12 viasuitable apertures 19, and to form a mixture of air and water. In detail, the throughchannel 55 presents an initial portion disposed in proximity to thenozzle 20, and having a cross-section greater than the cross-section of thechannel 23 at themouth 22; that part of this initial portion which extends radially from the projectingmouth 22 of thenozzle 20 defines saidapertures 19. According to a particular embodiment, as thetub 30 of the bath is approached, thechannel 55 presents a cross-section which gradually converges to transform the energy due to the water pressure into kinetic energy to increase the water outflow velocity. The final portion of thechannel 55 presents a constant cross-section, close to the cross-section of theejection hole 13. - Said operating means 51 comprise a
blade 52 positioned in thefirst chamber 11, and rigidly fixed to a first portion of arod 53, which is rotatably inserted through ahole 25 provided in theseparation wall 21, and of which the second portion is rigidly fixed to thevalving element 50. - The
rod 53 defines the axis of rotation of thevalving element 50 which is perpendicular (or a small angle off perpendicular) to the plane of theejection hole 13; as will be apparent hereinafter, this axis is positioned at a suitable distance from the barycentre of thevalving element 50. - The
blade 52 is shaped with a profile presenting a concave surface to the water from thesupply conduit 40, to increase the thrust of the water on theblade 52. - The
nozzle assembly 1 is connected to a further nozzle assembly, positioned downstream, by means of thedischarge conduit 42, which is connected to thesupply conduit 40 of said further nozzle assembly, saidnozzle assembly 1 being connected to a preceding upstream nozzle assembly by means of itssupply conduit 40, which is connected to the discharge conduit of said preceding nozzle assembly. - During hydromassage, a pump of the hydraulic system connected to the nozzle assemblies withdraws water from the
tub 30 of the bath and feeds it under pressure to thesupply conduit 40. The pressurized water enters thefirst chamber 11 to strike against the surface of theblade 52, to generate about the axis of therod 53 a first twisting movement able to position thevalving element 50 in a first open position. - Said open position (see
Figure 3 andFigure 4B ) is such that thechannel 55 becomes positioned coaxial to thenozzle 20, through which the pressurized water jet originates, and to theejection hole 13, to enable a mixture of air and water to be ejected towards thetub 30 of the bath. When hydromassage ceases, said valvingelement 50 moves into the closed position, with itsfront wall 56 adhering to theejection hole 13 to close it, and with itsrear wall 57 adhering to and closing the projectingmouth 22 of the nozzle 20 (seeFigure 4A ); by virtue of this, the water present in the tub is prevented from penetrating into thesecond chamber 12, or at least any organic substances are prevented from being able to flow back into the second chamber and from there to thefirst chamber 11, creating moulds and bacteria and possible blockage. Said closed position is achieved because of the fact that as the barycentre of thevalving element 50 is displaced from its axis of rotation (axis of the rod 53), the weight of thevalving element 50 creates a second twisting moment about the axis of therod 53, to return thevalving element 50 into its normal closed position, where it adheres to thecover 17 and to thenozzle 20. Elastic means, in particular atorsion spring 54, can be added to return thevalving element 50 into its closed position when water flow is lacking. - To render the open and closed positions of the valving element 50 (
Figures 4A and4B ) more stable, on the inner surface of thesecond part 16, in correspondence with thesecond chamber 12, there is positioned on one side afirst magnet 26 or equivalent means, and on the opposite side asecond magnet 27 or equivalent means, both able to attract thevalving element 50. In this case, this either has a totally or partly ferromagnetic body, or presents twocounter-magnets corresponding magnets 26 and respectively 27 and positioned on opposite sides of thevalving element 50; the magnets and counter-magnets are in geometrical relationship to each other such that when the valving element is in its closed position (Figure 4A ), themagnet 26 is in contact or near contact with thecounter-magnet 26a, whereas when the valving element is in its open position (Figure 4B ), thesecond magnet 27 is in contact or near contact with thecounter-magnet 27a. - Consequently the pairs of magnets and counter-magnets 26-26a and 27-27a serve to secure the valving element with a certain force, maintaining it in either its closed or open position. The force of the pressurized water which on entering the
first chamber 11 strikes theblade 52 is able to overcome the force of attraction between themagnet 26 andcounter-magnet 26a, whereas the thrust of thespring 54 and the weight of thevalving element 50 is able to overcome the force of attraction between themagnet 27 andcounter-magnet 27a when the thrust of the pressurized water against theblade 52 ceases. - In the embodiment shown in
Figure 2A , therod 53 possesses a threaded intermediate portion which is helically engaged with the likewise threadedhole 25 in thewall 21; this engagement is such that when thevalving element 50 is in its open position (as shown by the full lines inFigure 2A ), it lies at a distance (a few millimetres) from thehole 13; in contrast, when thevalving element 50 rotates into its closed position (as shown by dashed lines inFigure 2A ), the engagement with thehole 25 causes it not only to rotate but also to translate, at least a little, towards thehole 13, until itsfront wall 56 adheres to it. Effective adhesion of the valving element against thehole 13 can hence be obtained, with consequent effective closure thereof. - A non-limiting embodiment of the present invention has been described and illustrated, however it is apparent to the expert of the art that modifications can be made to the shapes, the details and the orientations, without however leaving its scope.
