Description
- The invention object of the present application relates to the technical field of devices for regulating the supply of running water for domestic use.
- The subject of saving and reducing the consumption of water is increasingly topical. Water is a precious commodity which is running out in many parts of the world and therefore it is worth sparing no efforts for responsibly using this important resource without waste.
- Quite often, the convenient availability of running water in the domestic environment such as in public sanitary facilities, shops, etc. brings users to make an improper use thereof. Valves are left open too long and large amounts of water are wasted. This leads to two types of waste, the first is related to an excessive use, with respect to the use which should be made, of the raw material i.e. the water itself (which is even more important where the water originates from tanks with finite capacity and not from the connection to the aqueduct, such as in the case of ships, campers, shelters, etc.); the second is related to using energy in connection with the use of this excess water, which energy is employed to pump, purify and heat it, etc.
- Therefore, the need is apparent for a device which allows the final users to limit wasting water within the domestic environment, and not only, during regular daily activities.
- In addition to saving on the volume of water used, 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 ΔT weighing on the boiler.
- This represents the first object of the present invention.
- Complete valves of devices to interrupt the flow, both of mechanical and electromechanical type, are currently marketed, which are provided as a first installation in sanitary systems. Devices of this type are widely used, e.g. in sanitary facilities of motorway restaurants or shops. It is apparent however that devices of this type are not applicable to pre-existing systems; therefore the need to have a device for reducing the consumption of running water which may also be used for ongoing installations, remains unfulfilled.
- This represents the second object of the present invention.
-
-
Fig. 1 shows a first preferred embodiment of the device according to the present invention, intended for valves. -
Fig. 2 shows a second preferred embodiment of the device according to the present invention, intended for shower water dispensers. - The present invention relates to the field of devices for limiting the water consumption and the energy related to said consumption. In particular, 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. In practice, 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.
- With reference to accompanying
Figures 1 and2 , the device object of the present invention comprises amain body 10 crossed by aconduit 11 communicating with the outside by means of inlet and outlet openings12,13. Saidmain body 10 further comprises: - a threaded
ring nut 14 arranged at said inlet opening 12 and adapted to be engaged with similar threading of standard type on the end part of the valve; - an anti-splash
tap nozzle filter 19 arranged at said outlet opening 13; - a
solenoid valve 15, preferably of NC (normally closed) type associated with saidconduit 11, preferably activated by a low-voltage, direct-current solenoid; - a
presence sensor 17 preferably of optical type (e.g. of proximity infrared or photodiode type); - a
control module 18 comprising a small circuit board adapted to perform the functions of: activating saidsolenoid valve 15 following the signal imparted by thepresence sensor 17 and managing the opening time of theaforesaid solenoid valve 15; - a
battery 16, preferably of rechargeable type, associated with saidsolenoid valve 15 and with saidcontrol module 18. - If said
battery 16 is of rechargeable type, 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 saidbattery 16. - In a preferred embodiment of the present invention, said
main body 10 further comprises a solar panel comprising a plurality of solar cells and a recharging module of saidbattery 16, associated with said solar panel and with saidbattery 16 and adapted to convert the output voltage from said solar panel into a stabilized direct voltage compatible with the recharging voltage of saidbattery 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 saidmain body 10. When an object approaches - e.g. the user's hand, a toothbrush, a razor, a glass, a dish, etc. - said presence sensor 17 - at an adjustable distance of the order of some centimeters - saidsensor 17 sends a signal to saidcontrol module 18 which activates saidsolenoid 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. - Said time T having elapsed, 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. - Instead, if a solenoid valve of NA (normally open) type is used, 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. In this case, dispensing the water is commanded by the user by means of a dedicated movement adapted to interfere with the action field of saidpresence sensor 17. - Despite the apparent complexity, which would lead to presume a considerable size, the miniaturization of the components allows practically every valve of conventional type to be assembled. 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. - Therefore small batteries are sufficient, also given the short cycle time actually performed during a standard day. For this reason, 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.
- For all those functions in which the arrangement of a continuous water jet is required, the
presence sensor 17 may be manually by-passable, e.g. by means of a specific switch placed outside saidmain 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.
- With reference to accompanying
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 thepresence sensor 17.
