Definitions

  • the present invention relates to a tap for the delivery of water comprising the characteristics expressed in the preamble to Claim 1.
  • taps are usually constituted by a delivery conduit and by a valve assembly through which it is possible to determine the delivery of cold water coming from an urban water pipeline and/or of hot water also coming from the water pipeline after passing through a boiler or similar heating apparatus.
  • taps which are able to deliver, in addition to the water coming from the urban pipeline, "pure” water coming from a filtering apparatus interposed between the tap and the urban water pipeline.
  • pure refers to any water having controlled chemical-physical characteristics, for instance coming from a suitable container or from a filtering and/or conditioning unit in turn connected to the water supply pipeline.
  • the tap described above has considerable bulk since it comprises two mutually distanced dispensing conduits and a filtering apparatus of large size, directly engaged to the body of the tap.
  • Document DE 4031764 discloses a water tap suitable for supplying filtered cold water, in addition to hot and cold water supplies. Cold water, hot water and filtered cold water are delivered thought a common delivery conduit leading to an outlet spout.
  • Document EP 01872601 which is herein referred as the most relevant prior art, discloses a water tap having a cold water inlet and a hot water inlet provided within a base member. At the inside of the base member, the cold water inlet and hot water inlet are respectively connected, through a first and a second control valves, to a first delivery conduit and a second delivery conduit obtained in a common delivery spout. Within the base member a third control valve is provided, for controlling the supply of cold water at main pressure through a water treatment cartridge to the delivery spout.
  • the US document 5,417,348 proposes a tap wherein a first and a second dispensing conduits destined respectively to dispense pure water and cold and/or hot water coming from the urban supply pipeline, are coaxially positioned one inside the other thereby constituting a single dispensing element Upstream of the first conduit is operatively engaged a first valve able to be switched between the open and shut position to determine the delivery of pure water, whilst downstream of the second conduit are operatively engaged a second and a third passage valves able to be switched between the open and shut position to determine respectively the delivery of cold and hot water coming from the urban water supply pipeline.
  • This configuration enables considerably to reduce the bulk of the tap, since the first and the second conduit are integrated inside each other.
  • both taps described above provide for a separate disposition of the conduit destined to the delivery of water coming from the water supply pipeline relative to the conduit destined to the delivery of pure water, since it is a generally held opinion that pure water, in order to be considered as such and to retain its characteristics, must never come in contact with water from the supply pipeline, or with the components destined to allow the passage thereof.
  • the delivery of the pure water in order to allow better guarantees in terms of quality of the pure water delivered, it is preferable for the delivery of the pure water to occur through the same passages dedicated to the delivery of the cold water, taking care to prevent pure water from coming in contact with hot water or with the components destined to the passage thereof, hot water being classifiable, from the hygienic-sanitary point of view, in a lower category than cold water.
  • the present invention relates to a tap for the delivery of water, comprising the characteristics expressed in the characterising part of Claim 1.
  • the tap 1 comprises a base 2 able to be fastened to a sink or washbasin by means of appropriate fastening means, and a delivery element 3 extending laterally from the base 2 and away therefrom.
  • the delivery element is engaged to the base 2 in correspondence with a first extremity 4 and is internally hollow to define a first delivery conduit 5.
  • the first delivery conduit 5 presents an outlet 6 obtained in a second extremity 7 opposite to the first extremity 4 of the delivery element 3.
  • Inside the dispensing element 3 is also present a second delivery conduit 8 having an inlet extremity 9 in correspondence with the base 2 and an outlet extremity 10 opposite to the inlet extremity 9.
  • the outlet extremity 10 of the second delivery conduit 8 ends in correspondence with at least an outlet port 11 obtained through the delivery element 3.
  • the outlet 6 and the output port 11 are advantageously mutually offset in axis and distanced, so that the fluids delivered through the first delivery conduit 5 are sharply separated from the fluid delivered through the second delivery conduit 8, providing the user also with the visual perception of the type of fluid delivered, based on its origin.
  • the output port 11 of the second delivery conduit 8 is obtained in the delivery element 3 between the outlet 6 of the first delivery conduit 5 and the base 2.
  • the second delivery conduit 8 it is possible to provide for the second delivery conduit 8 to develop to the second extremity 7 of the delivery element 3, so that the output port 11 is positioned adjacently to said extremity 7, with the outlet 6 of the first delivery conduit 5 interposed between the output port itself and the base 2.
  • first supply conduit 12 hydraulically connected to the first delivery conduit 5. More in detail, the first supply conduit 12 presents a first extremity 12a in fluid communication with the first delivery conduit 5 and a second extremity 12b hydraulically engaged to an inlet union fitting 13 for cold water coming from a first pipe 13a of the potable water supply pipeline. Also inside the base 2 extends a second supply conduit 14 hydraulically connected by means of a first extremity 14a to the first delivery conduit 5 and hydraulically engaged, by means of a second extremity 14b, to an inlet union fitting 15 for pure water. To the pure water inlet union fitting 15 is connected a second pipe 15a connected to the water supply pipeline with the interposition of a filtering element 15b or other purifying unit.
  • the tap 1 further comprises a third supply conduit 16 presenting a first extremity 16a in fluid communication with the inlet extremity 9 of the second delivery conduit 8 and a second extremity 16b hydraulically engaged to a hot water inlet union fitting 17.
  • a third pipe 17a coming from a boiler or other apparatus for supplying hot water.
  • valve means 18 To the supply conduits 12, 14,16, are also associated valve means 18 to place the first delivery conduit 5 in fluid communication with the first and the second supply conduit 12, 14 and the second delivery conduit 8 with the third supply conduit 16.
  • valve means 18 comprise a first valve 19 situated inside the base 2, operatively, interposed between the first delivery conduit 5 and the cold water inlet union fitting 13. This first valve 19 acts on the first delivery conduit 12 to regulate the passage of cold water in the first delivery conduit 5.
  • the valve means 18 further comprise a second valve 20, also positioned inside the base 2 operatively interposed between the second delivery conduit 8 and the hot water inlet union fitting 17.
  • the second valve 20 is active on the third supply conduit 16 to enable and regulate the delivery of hot water in the second delivery conduit 8.
  • a third valve 21 operatively interposed between the first delivery conduit 5 and the pure water inlet union fitting 17. Said third valve 21 is engaged on the second supply conduit 14 to enable and regulate the delivery of pure water through the first delivery conduit 5.
  • the first and the second valve 19, 20 can be actuated by means of a first common control organ 22 mounted on the summit of the base 2, selectively to open and close the supply of water, respectively hot and cold, to the first and to the second delivery conduit 5, 8.
  • the third valve 21 is able to be actuated by means of a second control organ 23, to open and close selectively the supply of pure water to the first delivery conduit 5.
  • valve 21 it is also possible to replace the third valve 21 with a switching valve or equivalent selector means to place the first valve 19 selectively in fluid communication with the cold water inlet union fitting 13 or with the pure water inlet union fitting 17.
  • the present invention solves the problems noted in the prior art and achieves the proposed aims.
  • Second of all the present invention providing for the passage of pure water through the same delivery conduit used for cold water, assures surprisingly greater guarantees relative to the characteristics of the pure water delivered.
  • the pure water is no longer subject to long intervals of permanence inside the delivery conduit since, through the same delivery conduit, flows also the cold pipeline-supplied water which is generally delivered more frequently than pure water.
  • the sharing of the same delivery conduit by the pure water and by pipeline water and the frequent use thereof prevents pure water from stagnating inside the delivery conduit.
  • the water that remains in the delivery conduit, after the closure of the third valve, is thrust outside by the subsequent flow of pipeline water.
  • the structure of the subject tap allows to deliver hot water separately from cold water and from pure water. This feature is important since it allows to prevent pure water from coming in contact with the components dedicated to the flow of hot water, containing a considerable quantity of impurities.
  • the subject tap is suitable to be advantageously used in all those circumstances in which, due to market demands or legal regulations, the separation of the hot water flows from the cold water flows is required.
  • the separate supply of hot water from that of cold water allows to eliminate the need to install in the base auxiliary one-way valves and/or to adopt other contrivances necessary in known taps, to prevent, when simultaneously delivering hot and cold water, the latter from invading, due to the pressure differential, the hot water delivery conduit.
  • this entails a simplification of the structure of the tap and consequently lower manufacturing costs than those required by common taps.
