Definitions

  • the present invention finds general application in hydraulic systems, particularly but not limited to house applications or generally in the civil building field and in all environments provide with sanitary systems wherein hot water is required for sanitary use and has as its object a sanitary water dispenser with electromagnetic waves heating.
  • traditional systems for heating water for domestic use generally comprise means for heating the water, usually an electric water heater or a gas boiler, which serves the whole system and which is therefore usually arranged at a distance with respect to the various delivery points, i.e. the taps.
  • the heating medium has an energy consumption linked to the need to preheat the water even in the absence of a supply request, to immediately send hot water at the opening of the tap.
  • KR100655105 wherein a microwave reflection rod is inserted in a hollow duet wherein there is a spiral-wound heating tube for the circulation of the cold water to be heated.
  • a first of these drawbacks is constituted by the fact that these systems require electrical power through connection to the network which docs not allow their convenient and rapid application in any point of the hydraulic system.
  • the object of the present invention is to overcome the above drawbacks by providing a sanitary water dispenser that prevents wasting energy and water.
  • a particular object is to provide a sanitary water dispenser that allows the water to be heated immediately and efficiently only at the time of the supply request.
  • Still another object is to provide a sanitary water dispenser which is easy and quick to install and which does not require direct electrical connection to a power supply network.
  • a sanitary water dispenser which, according to claim 1, comprises a conduit made of a material permeable to electromagnetic waves and adapted to be placed in fluidic connection with one of the outlets of the pipeline, heating means operating by means of electromagnetic waves and suitable for heating the flow inside said conduit in a controlled manner, means for powering said heating means which include means for generating radiofrequency waves and their transformation into energy electric for the power supply of said heating means.
  • the part of the dispenser equipped with the heating means will not require direct connection to the power supply network, as it can also be located at a distance from the points of withdrawal of electricity, greatly simplifying the positioning of the dispenser.
  • Fig. 1 shows a first embodiment, preferred but not exclusive, of a dispenser according to the invention, designed to be applied to a pipe of a hydraulic circuit at a water delivery point.
  • the dispenser indicated globally with 1, comprises a casing or heating chamber 2 designed to be mounted at a delivery outlet of a pipe of the hydraulic circuit for delivering drinking water and which houses a conduit 3 made of a material permeable to electromagnetic waves, such as tempered glass, lexan, arcopal or the like, and adapted to be placed in fluid connection with one of the piping outlets to allow the flow of water, indicated in the figure with the arrow.
  • a casing or heating chamber 2 designed to be mounted at a delivery outlet of a pipe of the hydraulic circuit for delivering drinking water and which houses a conduit 3 made of a material permeable to electromagnetic waves, such as tempered glass, lexan, arcopal or the like, and adapted to be placed in fluid connection with one of the piping outlets to allow the flow of water, indicated in the figure with the arrow.
  • Heating means are also provided for operating by generation of electromagnetic waves and which are designed to heat the flow inside the conduit in a controlled manner. Electric power supply means for the heating means are then provided outside the heating chamber 2.
  • the heating means comprise a generator 4 of electromagnetic waves, preferably microwaves, adapted to generate electromagnetic waves directly inside a preferably cylindrical radiation chamber 5, whose walls instead prevent the propagation of the waves outside and through which there is the passage of the conduit 3 in material permeable to microwaves.
  • the conduit 3 will be adapted to be placed in fluidic connection with common pipes for water (propylene, copper or other material), which, in turn, are connected to the piping of the hydraulic circuit.
  • this information is sent to an electronic control unit 9.
  • the upper pipe 10 connecting to the conduit 3 of the irradiation chamber 5 allows the transport of the heated water up to the nozzle 11 of the dispenser.
  • the electronic control unit 9 is the management component for regulating the correct operation of the microwave generator 4.
  • the control unit 9 receives the input signal (start) from a signal transmitter 12 when the tap is open or the photocell of the tap is activated to release the water.
  • the control unit 9 also receives information about the water pressure, through the pressure sensor 8, and the temperature at which the water must be heated through a temperature regulator 13.
  • the pressure sensor 8 is the component that detects the pressure of the cold water flow entering the lower pipe 6 with respect to the radiation chamber 5 and transmits the information to the electronic control unit 9.
  • the temperature regulator 13 allows the temperature to be adjusted by acting mechanically by means of a lever or by means of a digital control, in any case sending this information to the electronic control unit 9 from which it is managed.
  • the control unit 9 receives and manages three input signals, respectively from the signal transmitter 12, from the pressure sensor 8 and from the temperature regulator 13. Based on the parameters already set at the start, as the input signals vary, the control unit 9 will regulate the operation of the microwave generator 4: the emission of microwaves will be more or less intense as the water flow rate, i.e. its pressure in the conduit, and the temperature value required for the supplied water vary.
  • the electrical power supply means will be arranged at least in part externally to the heating chamber 2 to be located also remotely and at a supply point of the electric current.
  • the part of the power supply means located externally to the heating chamber 2 comprises a first transformer 14 of electrical energy into radiofrequency energy waves, which can be connected to a normal socket, for example from 220/240 V or other voltage based on the features of the local electricity grid, from which electricity is withdrawn and subsequently transformed into radiofrequency waves.
  • the first transformer 14 is electrically connected to a radio frequency transmitter 15 suitable to allow the radio frequency energy waves generated by the first transformer 14 to be released into the surrounding environment so that they may be picked up by a radio frequency receiver 16 located in the heating chamber 2, which in turn will convey them into a second transformer 17 of radiofrequency waves into electrical energy.
  • the signal transmitter 12 is the component that, when the tap is open, whether mechanically or through a digital sensor, sends a radio signal of different intensity from radio frequency waves that may be picked up by a signal receiver 18.
  • the signal transmitter 12 is also connected to the electronic control unit 9 which may send an activation input signal thereto.
  • the signal receiver 18 serves in turn to transfer the starting signal of the water dispenser (the tap or similar) to the first transformer 14 of electrical energy into radiofrequency energy waves.
  • the model of water dispenser adapted to be heated with microwaves described above may work without a cable connection, since it uses the energy obtained from a radio frequency energy wave emitter connected to a common electrical socket (220/240V).
  • This embodiment is particularly advantageous in rooms where there are several taps, such as in a bathroom in a home or even in public bathrooms of offices, restaurants, parking areas on the motorway where there are several dispensers of sanitary water, wherein it will be possible to manage the various dispensing points at the same time. This leads to significant savings for the electrical plant, being able to use any electrical outlet available in the room, instead of modifying the electrical plant to ensure access to electricity directly for each sanitary water dispenser.
  • Fig. 2 instead shows a model of the water dispenser 1 simpler than the previous one and provided with direct connection to the electrical system. In this case, the number of components is reduced and the functional architecture is simplified, without any change in terms of operating efficiency and performance.
  • This model is substantially identical to the previous one, except for the absence of all the components that manage the transformation of electricity into radio waves and vice versa and of those components that provide for the exchange of signals.
