- the air being so taken in forms a mixture with the water under pressure and this mixture is then ejected frontally by the nozzle 7.
- the flow rate of the jet produced by the nozzle 7 can be conveniently adjusted to a high degree of accuracy by rotating the same nozzle (which may to this purpose be provided externally with appropriate impressions 32, as shown in Figure 1), so as to vary in this way the relative angular position of the ports 21, 22 in the discoidal walls 14, 17 from a fully-open to a fully-closed condition of the cross-section of the passage provided for the water under pressure.
- said cross-section of the passage for the water under pressure is shown to reflect a condition in which it is half-open.
- such a safety provision may be further enhanced in its effectiveness by providing a check valve means in correspondence of the passage defined between the lead-in opening 9 of the nozzle 7 and said axial portion 23.
- said check valve means consists of a flexible diaphragm 33 having the shape of a ring, whose rear end is forcedly fitted around the axial portion 23, and whose front end is flared as shown in Figure 2 so as to elastically rest against the lead-in opening 9, thereby shutting it, only when a backflow of water towards the inner side of the semispherical body 8 occurs. Even this semispherical body 8 is therefore effectively and reliably protected against any possible backflow of contaminated water.
- a similar check valve means is also provided in the hole 28 of the pin 26, for instance in correspondence of the chamber 29.
- a valve means is preferably constituted by a flexible diaphragm 34 that is adapted to only close the air passage cross-section in the occurrence of a possible backflow of water from the nozzle 7 towards the orifices 6, through the passages 25 and 28.
Abstract
Description
- The present invention relates to an improvement in a water delivery head capable of being used in whirlpool bath-tubs or small whirlpool swimming pools so as to deliver a mixture of water and air under pressure.
- Water delivery heads for whirlpool baths are already known to substantially comprise a manifold-like body adapted to receive water under pressure and provided with at least an air suction opening, said air being taken in by Venturi effect and then substantially emulsified in the water under pressure for being finally delivered as an air-water mixture into the bath tub or pool through an adjustable nozzle that is supported in a swiveling manner by the manifold body. Usually, the swiveling nozzle has a substantially spherical outer surface cooperating with a corresponding supporting seat provided in the manifold body. As a consequence, the swiveling nozzle has a quite large surface area making friction with the manifold body and, therefore, making it difficult for the swiveling nozzle to be adjusted conveniently. In particular, this problem is undesirably worsened by the thermal expansion events which the various component parts undergo periodically, as well as by scale formation and/or foreign-matter and dirt build-up that may eventually occur on said component parts. As a result, it may well occur that adjusting the swiveling nozzle will eventually prove unacceptably inconvenient and difficult to perform with the desired accuracy.
- Furthermore, the adjustment of the flow rate of the water and air jet issued by the nozzle is usually performed by means of a central pin which is ajustable by being screwed up and down so as to be displaced axially with respect to a corresponding conical seat provided on the nozzle or, anyway, on the delivery head. It ensues that the afore mentioned scale formation and buildup can eventually make it impossible to adequately shut off the swiveling nozzle and, as a consequence, the delivery nozzle. On the other hand, a possibility to fully shut off the swiveling nozzle is quite desirable when the general operation of the whirlpool bath-tub is to be adapted to comply to particular needs, and also to prevent foreign matters from building up, encrusting and/or fouling the delivery head and the conduits associated therewith when the bath-tub is used to other purposes than whirlpool bathing. It will be easily appreciated that the latter is a problem that is particularly felt in cases such as those involving whirlpool bath-tubs installed in hotel rooms and the like.
- DE-U-8 812 993 discloses a delivery head of the above-mentioned type in which the outer surface of the swiveling nozzle cooperating with a support seat is substantially semispherical, thereby correspondingly rendering orientation of the swiveling nozzle more convenient. This solution, however, substantially suffers from the same drawbacks described above with regard to the impossibility to adequately shut off the delivery nozzle. The adjustment of the flow rate of the water and air jet issued by the nozzle is in fact performed, undesirably using a special tool, by screwing up and down an annular element supporting the swiveling nozzle, which is axially displaced accordingly with respect to a fixed air supply nozzle, thereby adjusting the flow rate. As a consequence, also in this case scale formation and buildup can make it impossible to adequately shut off the swivelling nozzle.
- It is a purpose and the main object of the present invention to provide a simple water delivery head for whirlpool bath-tubs, which is provided with a swiveling nozzle that is capable of being adjusted in a particularly convenient and smooth manner, substantially under all conditions of use.
- It is a further purpose of the present invention to provide a water delivery head of the above cited kind, in which foreign matters can effectively be prevented from entering both the delivery head and the conduits associated therewith.
- These and other aims are reached according to the present invention in a water delivery head for whirlpool bath-tubs embodying the characteristics recited in the appended claims.
- The characteristics, features and advantages of the present invention will clearly emerge from the following description which is given by way of non-limiting example with reference to the accompanying drawings, in which:
- Figure 1 is a schematic view showing the front elevation of the delivery head according to the present invention;
- Figure 2 is a view of a lengthwise cross-section of a preferred embodiment of the delivery head according to the present invention; and
- Figure 3 is a schematic rear view of a detail of the delivery head shown in Figure 2.
- Referring now in particular to Figures 1 and 2, it can be seen that the delivery head substantially comprises a manifold body 4 provided with at least an inlet orifice 5, through which it is adapted to receive water under pressure, as well as with at least an air suction orifice 6 (there are two of them in the embodiment described here by way of example), through which air can be taken into the manifold body 4. The latter can be installed on the
wall 18 of a whirlpool bath-tub, in correspondence of an appropriately provided hole, and preferably under interposition of at least a sealinggasket 20 therebetween, by means of a front ring nut 19 screwed in on the front inner surface of the manifold body 4; in a per sè known manner, said ring nut 19 may be covered with a ring 11 to essentially aesthetical purposes. The delivery head is further provided frontally with an outlet nozzle 7 having a tapered inner lead-in opening 9 and formed axially on a substantially semisphericalhollow body 8, preferably integral therewith. - Said
hollow body 8 is kept in an axial position inside the manifold body 4 by means of a supportingannular element 10 which is substantially curvilinear in its cross-section, is arranged between the twoelements 4 and 8, and is in turn fixed inside the manifold body 4 by means of a rear threadedportion 12 that is screwed down into a corresponding threaded portion provided inside the manifold body 4. - In particular, according to a preferred feature of the present invention the outer surface of the
semispherical body 8 co-operates slidably with saidelement 10 only in correspondence of an inner annular rib 13 thereof, which is provided in a front position and in relation to which saidbody 8 can be tilted and/or swiveled to adjust the nozzle 7. - Referring also to Figure 3, it can be seen that said
semispherical body 8 is provided on its rear side with a flexiblediscoidal wall 14, whoseperipheral edge 15 has preferably a stepped shape so as to be able to engagingly mate with the circumferential edge of thebody 8, which it is rotatably integral with (in a per sè known way, not shown here). - Furthermore, the
edge 15 of saiddiscoidal wall 14 engages externally with a correspondingperipheral edge 16 of a further flexiblediscoidal wall 17. The latter is concentric and adjacent to saiddiscoidal wall 14, but angularly integral with the manifold body 4 (in a per sè known way, not shown here). The flexibility of both saiddiscoidal walls respective ports discoidal walls - In the
discoidal wall 14, theports 21 surround anaxial portion 23, which is preferably formed integrally therewith, protrudes frontally and defines an axial passage. As a matter of fact, said axial passage extends from thewall 14 with a first flaredaxial portion 24 and a second cylindricalaxial portion 25; furthermore, the front end of theaxial portion 23 enters partially, in a loose way, the lead-in opening 9 of the nozzle 7. - The
discoidal wall 17 has a central hole having a diameter which is at least equal to the largest diameter of theflared passage portion 24, against the inner surface of which abuts the preferably rounded-off front end portion 27 of aconcentric pin 26 that extends from the rear wall of the manifold body 4. In particular, saidpin 26 has a diameter size lying between the diameter of saidcylindrical passage portion 25 and the largest diameter of saidflared passage portion 24, so that thediscoidal walls semispherical body 8 and the nozzle 7, can be caused to swivel to a very wide extent with respect to thepin 26 having a negligibly small friction surface. - The dimensions of the various component parts can be easily calculated so as to cause said end portion 27 of the
pin 26 to keep the various component parts pressed into a mutual axial engagement, as mentioned above, and, in particular, saiddiscoidal walls - The
pin 26 is provided with an axial through-hole 28 that communicates with theair intake orifices 6 in correspondence of achamber 29. This chamber is defined by aseat 30, which is formed on the rear wall of the manifold body 4, and an enlarged rear end 31 of thepin 26 which joins sealingly with saidseat 30. - Under operating conditions, when the manifold body 4 receives water under pressure from the inlet orifice 5, the water seeps into the
semispherical body 8 through theports discoidal walls axial portion 23 and the lead-in opening 9 of the nozzle 7. In correspondence of the front end of theaxial portion 23, the water flow brings about a negative pressure which takes in air from theorifices 6 through thehole 28 of thepin 26 and thecylindrical passage portion 25 connected therewith. - In a per sè known manner, the air being so taken in forms a mixture with the water under pressure and this mixture is then ejected frontally by the nozzle 7. The flow rate of the jet produced by the nozzle 7 can be conveniently adjusted to a high degree of accuracy by rotating the same nozzle (which may to this purpose be provided externally with
appropriate impressions 32, as shown in Figure 1), so as to vary in this way the relative angular position of theports discoidal walls tub 18 is going to be used for taking a bath in the traditional way, excluding a whirlpool action. In all these cases, fully closingports - According to a further preferred feature of the present invention, such a safety provision may be further enhanced in its effectiveness by providing a check valve means in correspondence of the passage defined between the lead-in opening 9 of the nozzle 7 and said
axial portion 23. In a preferred way, said check valve means consists of aflexible diaphragm 33 having the shape of a ring, whose rear end is forcedly fitted around theaxial portion 23, and whose front end is flared as shown in Figure 2 so as to elastically rest against the lead-in opening 9, thereby shutting it, only when a backflow of water towards the inner side of thesemispherical body 8 occurs. Even thissemispherical body 8 is therefore effectively and reliably protected against any possible backflow of contaminated water. - In a preferred way, a similar check valve means is also provided in the
hole 28 of thepin 26, for instance in correspondence of thechamber 29. Such a valve means is preferably constituted by aflexible diaphragm 34 that is adapted to only close the air passage cross-section in the occurrence of a possible backflow of water from the nozzle 7 towards theorifices 6, through thepassages - It will be appreciated that the afore described delivery head may be the subject of any modification considered to be appropriate, without departing from the scopes of the invention.
