Definitions

  • the invention object of the present application relates to the technical field of devices for regulating the supply of running water for domestic use.
  • said device should allow the consumption of hot water generated by gas or electric boilers to be reduced and, therefore, savings on the energy normally consumed for heating the excess water used. Said energy saving is considerable as the standard temperature of hot water is normally 45°C, with respect to an average ambient temperature of 20°C, with a 25°C ⁇ T weighing on the boiler.
  • the present invention relates to the field of devices for limiting the water consumption and the energy related to said consumption.
  • it relates to devices for limiting the consumption of water for sanitary systems.
  • the device according to the present invention is adapted to interrupt the flow of water from conventional dispensers such as valves and the like. It is an external separate device, not integral with or integrated within the valve body but adapted to be simply fixed to the valve itself by unscrewing the end part thereof usually comprising the small net or the anti-splash tap nozzle.
  • One of the innovative features of the device object of the present invention consists in the possibility of assembling and installing it on systems already being used, with no need for masonry, hydraulic modifications and without requiring the use of assembly tools.
  • the final user may directly apply it onto the valve in place of the anti-splash tap nozzle or of the small-net diffuser.
  • the device object of the present invention is absolutely stand alone and should not be connected to the electrical system during the operation thereof. It is equipped with independent supply and may include a small solar cell to recharge the internal supply battery, so as to avoid the need for external recharging devices.
  • the device object of the present invention comprises a main body 10 crossed by a conduit 11 communicating with the outside by means of inlet and outlet openings12,13.
  • Said main body 10 further comprises:
  • the device according to the present invention will further comprise a socket adapted to be connected to the outlet pin of an external power supply unit, preferably of AC-DC type, said socket having the electrical contacts connected to the terminals of said battery 16.
  • said main body 10 further comprises a solar panel comprising a plurality of solar cells and a recharging module of said battery 16, associated with said solar panel and with said battery 16 and adapted to convert the output voltage from said solar panel into a stabilized direct voltage compatible with the recharging voltage of said battery 16.
  • the operation of the device according to the present invention is simple. Said device is installed on the valve in place of the anti-splash tap nozzle. If a solenoid valve of NC (normally closed) type is used, said solenoid valve 15 is first closed, whereby water is not dispensed from the outlet opening 13 of said main body 10. When an object approaches - e.g. the user's hand, a toothbrush, a razor, a glass, a dish, etc.
  • NC normally closed
  • said presence sensor 17 - at an adjustable distance of the order of some centimeters - said sensor 17 sends a signal to said control module 18 which activates said solenoid valve 15; the latter will remain open in the holding position (therefore with very low currents absorbed) for a preset time T, e.g. 5 seconds.
  • the solenoid valve 15 automatically closes again while suspending the supply of water flow dispensed by means of said outlet opening 13.
  • the user may thus decide how much flow is to be actually use by simply moving close to or far from the sensor 17.
  • said presence sensor 17 is placed at a higher point, e.g. close to the fitting of the valve, so as not to interfere with the positioning of objects or of the user's hands close to the water jet.
  • dispensing the water is commanded by the user by means of a dedicated movement adapted to interfere with the action field of said presence sensor 17.
  • the electrical power absorbed by the solenoid of said solenoid valve 15 is of the order a few watts, with relatively high breakaway starting current but abundantly lower than 1 A.
  • the preferred embodiment of the present invention is particularly advantageous, which comprises the recharging circuit powered by the solar panel, because the ratio of the recharging time to the cycle time is very high, of the order of several hundred times.
  • the presence sensor 17 may be manually by-passable, e.g. by means of a specific switch placed outside said main body 10. This may be useful both for filling a vessel and for first achieving the water temperature required if greater than the ambient temperature.
  • the advantages related to using the device object of the present invention consist in reducing the consumption of both cold and hot running water in existing systems.
  • FIG. 2 a further preferred embodiment of the present invention is shown, which is adapted to replace the usual shower dispensers, in particular those used in domestic utilities and in sports facilities.
  • the structure of this preferred embodiment of the present invention is similar to that described above. Even in this case, replacing the existing shower body with the new one is sufficient, without the need for intervention by the plumber. Even in this case, the sensor will only make the water run when a part of the body is sufficiently close to and detected by the presence sensor 17.
