Abstract
Description
- The present invention relates to an improved hydromassage nozzle.
- It is known that 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.
- Specifically, 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.
- Another problem connected with known nozzles is stagnation of a certain quantity of water in the body of the nozzle during periods of inactivity, and this involves problems which need no further comment.
- 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.
- To achieve this object, according to a first aspect 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 of a duct which penetrates into the constricted section of said venturi tube and said constricted section is movable with respect to said duct forming the air suction passage between an open position in which passage of water is allowed through said constricted section and the total shutoff of said water passage, there being provided in said air suction duct a control valve which is caused to open by the negative pressure generated in the constricted section of the venturi tube when water under pressure is passing therein.
- According to another important aspect of the present invention 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.
- These and other aspects and advantages of the present invention will appear more clearly from the detailed description given below with reference to the annexed drawings wherein:-
- Fig. 1 is a diametrical cross-section of the nozzle according to the present invention;
- Fig. 2 is a view similar to that of Fig. 1 with the components of the nozzle in a different operative position;
- Fig. 3 is a cross-section which shows the adjustable body of the nozzle and Figs. 4 and 5 are respectively a plan view from above and a sectional view along plane V-V of Fig. 4 of an optional component of the nozzle of Fig. 3.
- It appears opportune to state that the nozzle illustrated in Figs. 1 and 2 provides all the features peculiar to the present invention, but it is understood that ownership of the selfdrainage feature may be provided separately from that of regulation of the stream issuing from the nozzle and vice versa.
- Referring therefore to Figs. 1, 2 and 3, the nozzle according to the present invention comprises an
adjustable body 10 which is seated in acasing 11 on which are provided in the same piece theunions - The
casing 11 is fixed to thewall 14 of the tub or pool (not shown) by means of a ring-nut 15 which engages by screwing an internal threaded part of thecasing 11. - To secure the
adjustable body 10 in an integral manner to thecasing 11 is provided ananular part 16 which engages by screwing a threadedportion 17 of saidcasing 11. - The
pads 18 preferaably of rubber or some other flexible material are integral with theanular part 16 for the purpose set forth below. - A
nozzle cover 20 is in turn fixed to theanular part 16 with thescrews 21 to mask aesthetically theflange 15 which fixes the nozzle. - On the bottom of the
casing 11 at thesuction duct 13 are providedsupport pads 22 for theadjustable body 10 made of rubber or some other flexible material for the purpose set forth below. - Now considering the
adjustable body 10 illustrated in detail in Fig. 3 it comprises aduct 23 shaped with a constricted section like a venturi tube. On the outside of theduct 23 is mounted asleeve 25 which forms aseat 26 in which is housed by threading abase 27 which bears as part of the same piece aduct 28 for air suction. Theduct 28 extends in the position illustrated in Figs. 1 and 3 to close theconstricted section 24 of the venturi tube, the watertightness of said closure being aided by ananular gasket 29. At the other end theduct 28 communicates with theair suction duct 13 through ahole 30 closed by avalve 31 which opens when there is negative pressure in theconstricted 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. - In the
base 27 are also made apertures orwindows 32 through which the interior of said base can communicate with theduct 12 which supplies water under pressure. - As appears clearly in the figures, the
base 27 and thesleeve 25 both have rounded outer surfaces so that they can operate together with thepads - Fig. 1 also shows that the
internal surface 19 of thecasing 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 thesurface 19 and offer no obstructions to natural discharge or drainage of water. - As can be seen in Fig. 2 moving of the
duct 23 along its axis toward the mouth of the nozzle frees an anular passage between the constricted section and theduct 28 so that the nozzle delivers the stream of water under pressure. The moving is adjustable and is secured by screwing and unscrewing theduct 23 with respect to thesleeve 25. - Figs. 4 and 5 illustrate an
auxiliary part 33 having abase 34 which couples with the outlet of theduct 23 and atapered tip 35 with anoutlet slot 36 which creates a fan-shaped stream which can cover a broader area to be subjected to hydromassage. - The present invention has been described for a preferred embodiment it being understood that conceptually and mechanically equivalent modifications and variants are possible and foreseeable without exceeding its limits and understood furthermore that each feature is to be considered both individually and in combination with the others.
