Definitions

  • the present invention pertains generally to shower heads composed of concentric elements, assembled as a pack and defining one, two, or more passages, in combination, to supply an equal number of different jets of water, and in which at least one of the elements is in the form of a knob and may be turned by hand to selectively divert the incoming water through a hole leading towards each of the supply passages according to the form of the desired jet.
  • the invention pertains to a shower head of the above mentioned type and incorporating pin devices destined to be introduced into set of water outlet holes to keep them clean and prevent the formation of scale that could lead to the holes getting clogged.
  • Another object of this invention is to propose a shower with several jets in which the pin cleaning unit remains inoperative while water is being delivered through any set of holes.
  • Yet another object of this invention is to propose a shower with a pin cleaning unit designed to prevent the formation of encrustations of scale in at least one set of holes; this unit may be activated voluntarily and only after stopping the passage of water from all the sets of holes.
  • This outlet 12 is placed parallel to a central leg 10' around which wings 10'' are located spaced at 120°, for example.
  • the leg 10' is integral with the shower body and designed to support the functional elements that control and channel the jets of water. These elements are fitted in a pack on or concentrically around said leg 10' held axially by a single screw 13 screwed onto the leg.
  • the body 10 comprises a fixed plate 14 at the level of the outlet 12 and a rotating distributor element 15 both centred on the leg 10'.
  • the plate 14 is provided with a through inlet hole 16 coinciding with the outlet 12 and designed for the passage of the water from said outlet towards the adjacent distributor element 15.
  • the through hole 16 is surrounded by seals both on the side towards the outlet 12 and on the side of the distributor 15.
  • the element 15 rests on said O-ring 18, and the seal around the through hole 16 on the side of the distributor 15 rests on a surface facing the latter in which some (three) distribution holes 19 --see Fig. 3--are provided spaced angularly on an arc concentric to the leg 12, which can be selectively positioned in coincidence with the inlet hole 16.
  • the distributor element 15 has, moreover, at a distance from said distribution holes 19, a stop tab 22 designed to engage in the slot 18 of the plate 14 to limit the maximum rotation of the distributor in both directions.
  • the distributor On its opposite face to the face in contact with the plate 14, the distributor has a cylindrical neck 23 surrounded by a peripheral flange 24.
  • the distributor 15 is placed concentrically in, and turns together with, a control knob 25 which is guided in rotation peripherally in the shower body 10 with a seal 26 placed in between.
  • the distributor and knob are coupled and constrained radially to turn together, besides being watertight thanks to a seal 27 placed at an intermediate level between the plate 14 and the peripheral flange 24 of the cylindrical neck 23.
  • the knob 25 has an internal flange 25' which is joined peripherally to the distributor 15 and which rests on the peripheral flange 24 by means of spacer ribs to define a water passage 28.
  • a first diffusor 29 is fitted inside the knob, between it and the distributor 15, and is designed to turn together with the knob and with the distributor.
  • the diffusor 29 has: a cylindrical portion that is joined with the periphery of the flange 24 of the distributor through a seal 30; on the outside, a flange 31 turned towards and coupled with the inside of the knob 25 through a seal 32; and, on the inside, a flange 33 turned towards and coupled with the neck 23 of the distributor through an additional seal 34.
  • the outer flange 31 of the diffusor is provided with a first ring of holes 35 distributed on a circle and designed to deliver a first set of jets of water according to the arrow A --see Fig. 2--.
  • the inner flange 33 of the diffusor has a number of holes 36 which permit the passage of water towards a ring element 37, placed in an ensuing compartment between the diffusor 29, the peripheral flange 24 and the neck 23 of the distributor and having a second ring of holes 38 for the delivery of a second set of jets of water according to arrow B --see Fig. 2--.
  • passages 39 for air suction there are passages 39 for air suction, and inside said ring element there may be a flow-breaking element 40.
  • a disc 41 and a second diffusor 42 are fitted, which together define a chamber housing a blade impeller or turbine 43 having radial water inlet passages and a third ring of holes 44 on its bottom to supply a third set of jets of water according to arrow C.
  • a ring 45 is provided which carries a crown of through pins 46 in corresponding holes obtained in the inner flange 25' of the control knob 25 and extending to the first ring of holes 35 designed to deliver the first set of jets of water (arrow A).
  • a recovery spring 48 between the inner flange 25' of the knob 25 and the ring 45 tends to keep the latter moved towards the wings 10 in such a position that the pins 46 are normally moved towards the inside of the shower, away from the respective ring of holes 31.
  • the interaction of the protrusions or cams 47 with said wings 10'' determines an axial movement of the ring 44 in opposition to the action of the spring 48, that is towards the outside of the shower, so that the pins enter the respective ring of holes 35 (see Figs. 4, 4a).
  • the rotation of the distributor 15 corresponds to the rotation of the knob 25. This permits to selectively position each of the distribution holes 19 in coincidence with the inlet hole 16 of the fixed plate 14 and correspondingly the delivery of a type of jet of water A, B or C as preferred, as occurs in the shower of the above mentioned Italian Patent application N.7073-B/86.
  • the ring 45 bearing the pins 46 also turns with the knob 25.
  • the pins While the knob is rotating for the selection of the type of water jet A, B or C to be delivered, the pins always remain inoperative, away from the holes 35.
  • the protrusions or cams 47 are inserted between the radial wings 10'' without ever engaging with them, and the spring 48 keeps the ring 45, and with it the pins 46, away from the holes 35.
  • the ring is moved axially so that the pins are inserted in the holes 35 only when the knob 25 is turned, in one direction or the other, to reach a limit stop defined by the arc slot 17 of the fixed plate 14 in co-operation with the tab 22 on the distributor.
  • the distribution holes 19 of the distributor are all far from the water inlet hole 16 so all delivery of water through the shower ceases. Only at this stage do the protrusions or cams 47 of the ring with pins engage with the wings 10'' --see fig. 4a--causing the pins to advance into their operating position.
  • prongs 49 may be provided at the opposite ends of the arc slot 17 stopping the distributor stop tabs 22 by friction, i.e. by force.
  • This embodiment is shown in Figs. 3 and from 3a to 3d, which illustrate several conditions of rotating and stopping the distributor (of which only the stop tab is visible) in various positions.
  • Figs. 6 and 6a lastly show an embodiment with a limit stop with a spring 51 similar to the one of Figs. 5, 5a, but also with a positive stop ledge 52.
  • the cleaning pins always stay in an inactive position while any jet of water is being delivered through the shower. They are moved into an active position only after an additional rotation, either in one direction or in the opposite direction, of the control knob that first causes the water being delivered through the shower to be stopped and then forced introduction of the pins into the respective holes. When the knob is again turned for a fresh delivery of water, the pins automatically go back into the operating position as a result of the action of the recovery spring combined with the ring 44 bearing the pins.
