Abstract

Water delivery head for whirlpool bath-tubs and the like, comprising a manifold body (4) with a pressurized-water inlet orifice (5) communicating with a nozzle (7) through adjustment means for the water passage cross-section and a hollow body (8) which is integral with the nozzle and capable of being swiveled with respect to the manifold body. The latter further comprises two air intake orifices (6) communicating with the lead-in opening (9) of the nozzle so as to generate an air-water mixture being ejected from the same nozzle. The hollow body (8) has a semispherical surface that cooperates frontally in a sliding manner with an external annular rib (13) that is fixed to the manifold body (4). Said hollow body (8) is coupled on its rear side with a flexible discoidal wall (14) having a flared central passage (24) pivoting on a central pin (26) that is fixed at the rear to the manifold body (4) and is provided with an axial hole (28) through which the air intake orifice (6) communicates with the nozzle (7). The nozzle (7) can be swiveled conveniently, with no appreciable friction problem. <IMAGE>

Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a head for supplying water to a whirlpool bath which is used in whirlpools or small whirlpools where a mixture of water and air under pressure is supplied therethrough.

BACKGROUND OF THE INVENTION A bath consisting of a pipeline having at least this air is blown in a metal

also by the deposition of limescale or dirt that is deposited on the panels. As a result, the head control and the difficulty in adjusting the flow to the desired accuracy are very uncomfortable.

In addition, the adjustment of the flow rate of the water and air nozzle in the head is usually accomplished by means of a central pin which is adjustable by screwing up and down so that it can move axially relative to the conical seat in which it moves and with which the head is provided. It is precisely the deposition of scale and dirt that causes the adjusting pin to fail to function adequately and cannot be completely closed. However, a complete closure of the swivel head is required when major swirl bath operations are required when it is necessary to adjust it or when deposits or limescale need to be removed from the head. Closure is also necessary when the bath is used for traditional purposes and not for a whirlpool bath. This need arises especially with similar baths installed in hotel rooms and similar facilities.

SUMMARY OF THE INVENTION

The aforementioned drawbacks are largely solved by the water-supply head of the present invention, characterized in that the bell is formed by a hemispherical surface on which a sliding annular rib faces the chamber and is attached to the chamber, the hemispherical bell being connected in its rear part to a first flexible disk wall which is rotationally integral therewith and consists of an axial extension projecting forward to the inlet opening of the outlet nozzle and forming a central channel with a funnel portion rotatably mounted at the front end of the tip its rear part to the chamber and is provided with a hollow opening through which the suction inlet is connected with the outlet nozzle.

The head for the water supply to the spa according to the invention is a simple design with a rotating nozzle, which can be conveniently and accurately adjusted to the desired flow rate.

Furthermore, the design of the head prevents foreign particles from penetrating both inside the head and into the associated fittings.

In the embodiment shown, the front ring 19 is covered by a cover 11 for aesthetic reasons. The head is further provided on the face of the outlet nozzle 7,. which has a chamfered inner inlet 9 and whose part is also axially disposed a half-spherical bell 2, which is an integral part.

The hemispherical bell 3 is maintained in an axial position within the chamber 4 by means of a ring 10 which is curved in cross section and is interposed between the chamber 4 and the hemispherical bell 8. The ring 10 is fixed inside the chamber 4 by a threaded shoulder 12,

which fits into the corresponding thread in Chamber 4. External hemispherical wall bell 3 comes into contact = ring 10 only in places where to it is supported by the rib 13

It can be seen in FIG. 3 that the rear portions are provided with a resilient edge 15 preferably having a schema:

The resilience of the passages 21, 22 is identical to each other and shaped as regular openings in concentric circles. In addition, the two disc walls 14 and 17 are preferably slightly bent relative to the head portion of the head.

In the first disc wall 14, the passages 21 surround axially the extension 23, which in the preferred embodiment is formed with them as an integral part, are frontally permeable and forms an axial channel. This axial channel extends from the disc wall 14 with the funnel portion 24 and the cylindrical axial portion 25. Further, the front end of the axial extension 23 partially enters the internal inlet 9 of the outlet nozzle 7.

The second disc wall 17 has a central bore with a diameter that is at least equal to the largest inner diameter of the funnel portion 24. The inner wall of the tubular portion 24 is planted with a protruding surface.

Under operating conditions, when the chamber 4 receives water under pressure from the inlet 5, water penetrates the arc bell 8 through the passages 22 and 21 of the disc walls 17 and 14 and flows through the channel defined by the axial extension 23 and the internal inlet 9 of the outlet nozzle 7. adapter 23 with dcsta-

It can be noted that adjusting the passages for the water flow is due to a simple rotating sliding movement instead of moving in the axial direction, so that impurities or foreign particles cannot prevent the flow from being easily and completely shut off. This need may arise without a swirl effect. In all orifices, the fully enclosed passages 21 and 22 prevent the penetration of dirty or contaminated water that could enter the head through the front nozzle 7 to reach chamber 4, inlet 5 and natural pipes not shown but associated with the assembly.

According to another embodiment of the invention, this safety effect can be enhanced by means of a check valve which has been placed in the channel defined by December between the internal ones;
