Definitions

  • the present invention relates to a blowpipe for shower and the like of the type pointed out in the preamble of the first claim.
  • blowpipe for shower and in particular the fixed blowpipe, i.e. the blowpipe that cannot be moved by a user.
  • This blowpipe in fact has almost abandoned its classic, usually cylindrical, shape of a hollow body provided with a dispenser, i.e. a disk having a plurality of nozzles from which water comes out, and with a pipe adapted to bring the water to the inside of said hollow body.
  • blowpipe for shower One of the newest and most adopted shapes of blowpipe for shower is that commonly referred to as "sandwich" shape.
  • This blowpipe can consist of a body having two plates, a lower one provided with holes, and an upper one having a cavity adapted to enable the water to reach said holes.
  • the plates substantially having the same shape and extension, are superposed and welded or glued to each other so as to confine a substantially closed inner chamber adapted to allow the water to reach the holes formed in the lower plate without ducts or other similar elements being required.
  • a drawback of these blowpipes is the fact that the jet coming out of the holes is not uniform. This drawback is partly obviated by the presence within said chamber of a dispenser provided with nozzles inserted inside the holes so as to direct the water jet coming out of the blowpipe.
  • a waterworks through a duct adapted to bring the water to the upper plate.
  • a suitably shaped connecting element that, in addition to connecting the two aforesaid components, defines a second inner chamber allowing the water to be uniformly distributed among the different nozzles thereby enabling creation of a uniform jet.
  • blowpipes due to their own nature, have very different pressures in the different portions of the inner chamber. These different pressures give rise to great pressure increases in some portions and weak pressures in other portions. Said drawbacks bring about a short duration of the blowpipes due to the continuous deformation caused by the liquid pressure, in particular at the edges of the inner chamber, thus producing a quick deterioration.
  • blowpipes are then characterised by a construction complexity giving rise both to high costs and long production times.
  • the technical task underlying the present invention is to conceive a blowpipe for shower and the like capable of substantially obviating the mentioned drawbacks.
  • the invention aims at conceiving a blowpipe for shower that can be assembled through simple and quick operations.
  • Another important aim of the invention is to make a blowpipe on which maintenance operations can be carried out easily.
  • a further aim of the invention is to make a blowpipe having high aesthetic features.
  • blowpipe for shower and the like is generally identified by reference numeral 1 .
  • the blowpipe 1 can further comprise a fastening block 5 rigidly secured to the base plate 2 and suitable for engagement of the blowpipe 1 with a supporting structure, a wall for example.
  • blowpipe 1 Almost all the elements forming the blowpipe 1 are made of stainless steel.
  • the base plate 2 in addition to using stainless steel, can be also made of carbon or other material having high aesthetic qualities.
  • plate 2 constitutes the base component to which almost all the components of the blowpipe 1 are fixed in a releasable manner, i.e. in a manner adapted to enable easy removal of said connections.
  • the base plate 2 is secured to the gasket 4 and the upper element 3 by first releasable connecting means 6 and to the fastening block 5 through second releasable connecting means 7 .
  • Both the first 6 and second 7 releasable connecting means preferably consist of at least one bolt, i.e. an element made up of a screw and a nut 6b and 7b .
  • the screw is a screw stud 6a and 7a .
  • the screw studs 6a and 7a are advantageously welded to the base plate 2 on the opposite surface relative to the exit surface of the water jet from the blowpipe 1, as shown in Figs. 3 and 4 .
  • gasket 4 too is suitably provided with holes into which the screw studs 6a and 7a are introduced.
  • connection between the fastening block 5 and the base plate 2 can be of the unreleasable type and therefore obtained by welding, for example.
  • the base plate 2 preferably has a contoured flat shape with a substantially constant thickness.
  • the perforated portion 2a, belonging to the base plate 2 is provided with outlet holes 2b ( Fig. 2 ) defining the water jet coming out of the blowpipe 1.
  • This perforated portion 2a is therefore defined by at least the base plate portion in which said outlet holes 2b are formed ( Fig. 2 ).
  • the assembly of the individual nozzles 8a is housed within the inner volume 1a and they constitute a dispenser 8 , i.e. an element adapted to enable the water jet coming out of the blowpipe 1 to be directed.
  • nozzles 8a are adapted to direct the water jet, being preferably inserted by friction fit into the holes 2a, as shown in Figs. 3 and 4 .
  • Nozzles 8a are advantageously distinct from each other so as to enable both an easier fitting and a simpler and easier replacement.
  • Nozzles 8a and therefore dispenser 8 represented by the assembly of nozzles 8a are made of descaling silicone material, i.e. a material adapted to limit formation of lime deposits that would cause clogging of nozzles 8a.
  • nozzles 8a are made of silicone rubber.
  • the shape and sizes of the volume in which nozzles 8a are inserted are substantially defined by the upper element 3 and gasket 4 advantageously having such a shape that the inner volume 1 a enclosed by them has an almost constant height, calculated along the perpendicular to the base plate 2 ( Figs. 3 and 4 ).
  • the upper element 3 is therefore placed at the perforated portion 2a and, in detail, it is adapted to cover the portion of the base plate 2 in which the outlet holes 2b are formed.
  • the upper element 3 once it has been fixed to the base plate 2, is almost parallel to said base plate 2.
  • it is of flat shape and, more specifically, the upper element and base plate are both flat.
  • the element 3, to the aim of improving the aesthetic appearance of the blowpipe 2, has a smaller extension, along the major extension surface of the blowpipe 1 itself, relative to the extension of the base plate 2.
  • the outer profile belonging to element 3 is placed to a given distance from the outer profile of the base plate 2 along the major extension surface of the blowpipe 1 itself. In particular, this distance is substantially included between 5 mm and 40 mm.
  • the upper element 3 as previously described, is connected for fluid passage with an outer waterworks not shown in the figure. This connection is made through a duct 9 adapted to bring the water into the inner volume 1 a and a coupling and dispensing means 10 adapted to connect the duct 9 to the upper element 3 ( Fig. 1 ).
  • the upper element 3 has a cavity 3a adapted to enable access of the fluid to the inner volume 1 a. More specifically, in order to have an optimal distribution of the fluid in the inner volume 1a and therefore an almost homogeneous jet from all nozzles 8a, preferably the perforated portion 2a, at said cavity 3a, has a non-perforated sector 2c, adapted to prevent the water, as soon as it has entered the inner volume 1a, from coming out of such a region in a prevalent manner therefore giving rise to a non-optimal jet.
  • Duct 9 is preferably a flexible hose and at the two ends has connection means 9a , preferably of the releasable type, adapted to enable quick and ready connection of duct 9 to the waterworks and to the coupling and dispensing means 10.
  • connection means 9a it is secured to said waterworks at the fastening block 5 having a suitable housing enabling the connection means 9a to be enclosed at least partly therein, thus improving the aesthetic appearance of the blowpipe 1.
  • the coupling and dispensing means 10 advantageously consists of two portions that can be fastened to each other in a releasable manner, through threading for example.
  • the coupling and dispensing means 10 ( Fig. 2 ) therefore comprises a first portion 10a forming the coupling means and adapted to be directly secured to the duct 9 and a second portion 10b forming the dispensing means or dispenser which is suitably shaped and adapted to be secure to the upper element at cavity 3a.
  • the coupling and dispensing means 10 can contemplate a second gasket 10c consisting for example of an O-ring or other mechanical static sealing piece that, under compression between the two portions 10a and 10b, prevents water leakage.
  • the coupling and dispensing means 10 is of the fixed type, i.e. once connection has been made, it does not allow any relative motion of the base plate 2 relative to duct 9. Alternatively, this coupling and dispensing means 10 is able to allow a relative motion between said two components. In particular, as shown in Fig. 5 , the coupling and dispensing means 10 allows a relative rotation between the base plate 2 and duct 9.
  • blowpipe 1 is devoid of the fastening block 5 and its engagement with a supporting structure is obtained through duct 9.
  • gasket 4 In order to ensure a perfect connection between gasket 4 and the upper element 3, the outer profile of said gasket 4 is substantially coincident with that of the upper element 3.
  • Gasket 4 is further preferably made of a polymeric material and in particular silicone material.
  • the base plate 2 is prepared by welding the screw studs 6a and 7a thereon, nozzles 7a are positioned in holes 3b, the second portion 10b of the coupling and dispensing means 10 is linked to the upper element 3 and then the different components are connected to the base plate 2.
  • duct 9 is joined to the upper element 3 the first portion 10a being locked to the second portion 10b and the fastening block 5 is secured to the base plate by the second releasable connecting means 7.
  • the second gasket 10c is preferably interposed between portions 10a and 10b.
  • one component is wished to be replaced, such as one or more nozzles 8a, it is sufficient to remove duct 9 and then the upper element 3, through unscrewing of nuts 6a so as to enable access to nozzles 8a, and if necessary, gasket 4 ( Fig. 6 ).
  • the link created by the first connecting means 6 is released, i.e. nuts 6b are unscrewed from the screw studs 6a and at least the upper element 3 is then lifted so that there is easy access to the inner volume and replacement of the faulty nozzles can be carried out readily.
  • this operation allows cleaning of nozzles 7a for example, eliminating possible foreign bodies obstructing them.
  • the invention achieves important advantages.
  • a first advantage is represented by the fact that maintenance of blowpipe 1 can be carried out very easily due to the almost complete absence of connections obtained by welding or other similar means that would not enable access to the inner volume 1 a.
  • blowpipe 1 is provided with releasable connecting means 6a enabling the link created by it in an independent manner to be released, so that one or more of the components of the blowpipe can be easily replaced or repaired.
  • the connecting means 6 allows easy replacement of nozzles 8a, which nozzles are the critical component of the blowpipe 1, i.e. the component characterised by frequent breaking and high possibilities of clogging. In particular, this operation is simple and can be carried out also by unqualified staff and therefore by a classic user.
  • Another advantage is represented by the high reliability and duration of the blowpipe 1, also ensured by the possibility of intervening directly and exclusively on the damaged components in a simple and quick manner.
  • Said advantage is given by the substantially constant height of the inner volume 1a ensuring an almost constant pressure within the inner volume 1a itself.
  • This constant height enables dangerous pressure peaks to be avoided at the edges, which peaks would lead to quick deterioration of the blowpipe 1.
  • This advantage is achieved in a synergetic manner due to the absence of welds and glues inevitably causing sudden dimension changes and consequent variations in the height of volume 1a.
  • dispenser 8 as it consists of distinct nozzles 8a, can be easily assembled, and even partial replacement of same is allowed. In addition it is cheaper, since with a single mould all nozzles 8a available in blowpipes 1 of any shape can be obtained.
  • blowpipe 1 has a low price and is characterised by reduced production times due to the simple connections between the different components.
  • a further advantage belonging to the blowpipe 1 is the high aesthetic quality of same.
  • this advantage is due to the fact that the reduced sizes of the upper element 3 relative to the base plate 2 enable it to be hidden to the sight.
  • the obtained blowpipe for shower and the like has a low thickness.
  • a not least advantage is represented by the high uniformity of the water jet due to the absence of holes 2b at the cavity 3a.
  • this advantage is also obtained thanks to the presence of the non-perforated sector 2c placed at the cavity 3a and ensuring that the water coming out of duct 9 is distributed uniformly within the volume 1a.
