Shower with nozzles for the delivery of atomised jets of water

Abstract: The invention concerns a shower for the delivery of differentiated jets of water characterised by the fact that it incorporates injector means (35) to generate and deliver atomised jets of water through a crown of atomiser nozzles (27) governed by a rotating distribution element.

Description: This invention concerns showers for the delivery of differentiated jets of water. Already available on the market are those showers with a head housing concentric elements assembled as a unit and which form a combination of one, two or more types of passage for the delivery of the same number of different jets of water, and where at least one of the elements can be rotated by hand to distribute the incoming water through at least one feed hole and selectively through each type of passage depending on the shape of the required jet of water. Such showers are usually pre-set for the delivery of different types of jets of water, such as, fine, delicate (soft), pulsating or massaging, etc, and the methods used to move from one type of jet to another are known. For example, document EP 0 437 164 discloses a shower or douche having two different water outlets capable of being alternately selected. In particular, the shower is provided with a water outlet having a plurality of jets and another atomised water outlet. Such atomised water outlet is joined to a plurality of sprayers, each one comprising a central hole and up to four. slots arranged in the form of a cross for the flow of the water, the hole and the slots being formed in the bottom of a cylindrical body. The foremost aim of this invention is to produce and supply a shower capable of delivering atomised jets of water besides the other common types of jets of water. Another aim of this invention is to propose a shower with incorporated injectors-diffuser units having a particular configuration and combination to generate and deliver atomised water through a crown of nozzles with the advantage of having water finely subdivided for various uses that is not possible to achieve with the more traditional showers. Such aims can be accomplished with a shower which is substantially in compliance with claim 1 and which will be hereafter described in more detail and with reference to the attached indicative and not limiting drawings. In said drawings Fig. 1 shows a cross-section of the shower assembly; Figures 2, 3 and 4 show, respectively, the external, internal and cross-section of a diffuser-holder flange; Figures 5, 6 and 7 show, respectively, the views of a diffuser with nozzles; Figures 8, 9 and 10 show similar views of an injector; and Figures 11 and 12 show two detailed views of the injector in Fig. 8. The shower shown is composed of a body 20 having a longitudinal duct 21 connected to a water inlet pipe - not indicated - having an outlet 22 towards well known elements not requiring definitions, whose purpose is to control the water delivery according to the different jets. In the example shown, such elements include a multiple-way conveyor-distributor 23 equipped with a control knob 24 capable of selectively deviating the water from the incoming duct 22 to a first series of external nozzles 25 for the delivery of fine jets of water, to a diffuser with nozzles 26 for delivery of pulsating or massaging jets of water, and to a crown of nozzles 27 for the delivery of the water in further shapes of jet. According to this invention this crown of nozzles 27 is aimed at delivering for the most part atomised water. Such atomiser nozzles 27 have the form of teats in a ring-shaped diffuser 28, preferably a rubber one, together with the first series of nozzles 25, they too in the form of teats - figures 5 - 7. The ring shaped diffuser 28 is held and coupled with a rigid flange 29 presenting a series of holes 30 for the first order of nozzles 25 and a second series of holes 31 for the crown of nozzles 27, figures 2 - 4. The diffuser with nozzles 26 for the massaging jets of water is positioned in the centre of the flange 29 - Figure 1 - and receives water from a analogous duct 26 controlled by the distributor. A ring 32 with water ducts, coinciding with the first order of nozzles 25 is located around the flange 29. The water reaches these nozzles by flowing through a duct 33 governed by the distributor 23. A rigid ring 34, which holds several injectors 35 has been inserted in the ring-shaped diffuser 28, each positioned in correspondence with one of the nozzles in the crown of nozzles 27. The injectors 35 receive water through the holes that can be opened and closed as often as one wishes, governed by the distributor 23 when the form of the jet of water to be delivered is selected. Each injector 35 is made up principally of a cylindrical element projecting from the ring 34 towards the inner chamber of its corresponding nozzle 27. The projecting element - Figures 8 - 12 - presents longitudinal lateral channels 37, each of them in communication with a central chamber 38 provided at the base of the element and open towards the atomiser nozzle 27. More precisely, each longitudinal lateral channel 37 is connected to this central chamber through a non-radial passage 39, but orientated at a tangent to the cavity itself - Figure 11 -. In this way, when the distributor 23 is in the position to send water to the injectors 35, the water is obliged to pass through the lateral channels 37 of each injector and compelled to enter its lower central chamber 38 through the tangential passages 39. Thanks to the location of these passages water will whirl into the chamber 39 increasing its speed and pressure and creating, however, the conditions to deliver the water in a fine atomised form from the corresponding nozzles 27. The overall effect of the atomised water is particularly appreciated and useful for various uses in the care of hair and skin.

Claims: A shower for the delivery of differentiated jets of water comprising concentric elements, assembled as a unit and which form a combination of one, two or more types of passage for the delivery of the same number of different jets of water, in which at least one of the elements can be rotated by hand to distribute the incoming water through at least one inlet hole selectively towards any order of passage depending on the form of the required jet of water, the shower incorporating injector units (35) to generate and deliver atomised jets of water through a crown of atomiser nozzles (27) governed by the rotating element, wherein said injector units (35) include an injection element for each atomiser nozzle (27), and wherein said injection elements are attached to a supporting ring (34) and each one is inserted into its corresponding atomiser nozzle, characterised in that each injection element (35) is prevalently cylindrical and presents longitudinal lateral channels (37), a central chamber (38) at its base opening towards the corresponding atomiser nozzle (27) and some passages (39) which connect said lateral channels (37) to said central chamber (38), said passages being orientated tangentially to the chamber creating a whirl effect and atomising the water exiting such atomiser nozzles. A shower according to claim 1, in which said injection elements (35) are projecting from said ring (34), are inserted with force into the atomiser nozzles (27) and receive the water through the holes (36) in correspondence to said ring and under the control of the rotating element responsible for water distribution. A shower according to claim 1 or 2, in which the atomiser nozzles (27) are formed in a rubber ring shaped diffuser together with a further series of nozzles (25) for the delivery of another form of jets of water, in which said diffuser is coupled with a rigid supporting flange, and in which the ring holding the injection elements (35) is force fitted to said distributor so that the injectors are inserted into the atomiser nozzles (27).
