Description

OBJECT OF THE INVENTION

The present invention relates to an electronic faucet for public and domestic uses, whose obvious purpose is to enable water dispensing without the need to touch the faucet.

The object of the invention is to ensure that the power supply is obtained from the operation of the tap without the need for electrical installations or accessories, as is conventionally required.

BACKGROUND OF THE INVENTION

As is known, an electronic faucet has a sensor, usually infrared, by means of which the activation of the faucet is carried out without touching it, operating it for a predetermined time, to close automatically afterwards, so that the electronic faucet can Also considered as a timed tap.

Likewise, it is known that the power supply can be carried out by means of the conventional electrical network, directly, or through batteries incorporated inside or outside the tap itself.

comfort of use much appreciated by the user or people with decision-making capacity when performing an installation, since on the one hand they are hygienic, since it is not necessary to touch them to activate or stop them, that is to say that physical contact is totally avoided and with this, any type of possible contagion, while on the other hand, not having to carry out the operation of the corresponding opening and closing lever is a convenience for the user, to which the possible electronic timing regulations must be linked , activation distance, response reaction after approaching the hand, all of which makes the electronic tap a very attractive product.

However, electronic faucets are expensive, not only for the tap itself but, in the case of multiple installations, for the necessary electrical installation, transformers, placement of sensors on ceilings to prevent vandalism, and other auxiliary elements, which They greatly increase the cost of the tap.

On the other hand, another drawback presented by electronic faucets is that, when they are placed in a public place, they are subject to acts of vandalism, being able to cite blows without any explanation about the tap body itself, breakage of sensors, dismantling of the aerator, cable and battery start, etc.

In short, if the inconveniences mentioned above are added to the high cost of each tap unit, it is evident that the electronic faucet loses its attraction and generates some fear when choosing this type of faucet.

In addition we must unite the fact that electronic faucets

Electrically powered (Battery replacement).

Well, despite all the above, the market continues to demand electronic faucets, even in small quantities, because at first sight and in order to solve the exposed problem, it is necessary to conceive a tap whose structural and operational characteristics are resolved. the problems and inconveniences previously reported.

DESCRIPTION OF THE INVENTION

The electronic faucet that is pre-cast has been designed precisely to solve the problem described above and solve all 10 problems mentioned.

More specifically, one of the fundamental characteristics of the tap of the invention is that it is electrically self-powered during its own operation, not requiring auxiliary connections of electricity or external elements for its operation, since the water flow itself that gives way, moves a propeller or turbine that in turn produces a rotating movement capable of operating an internal power generator that provides sufficient electrical current to maneuver the solenoid valve that electronic taps have for this purpose, to open and close the passage of water . In addition, the remaining electrical energy will accumulate in the electric battery that is not necessary to replace, since it is being permanently recharged.

Another feature of the invention is that all the components that participate in the faucet assembly, such as the electric generator, supply battery, solenoid valve and presence sensor, are mounted inside the faucet body, being inaccessible from the exterior, because the new tap can be considered as vandal-proof design, since the only removable element and subject to any vandalism is the corresponding aerator, although this fact is clearly unavoidable, although the tap can have a also a vandal-proof aerator since a special tool for disassembly will be required.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the tap of the invention is constituted, as is conventional, from a tap body (1), with an outlet pipe (2) in which the corresponding diffuser is provided. jet or aerator (3), presenting a base (4) fixed by internal screws (5), and the whole assembly fixed by a nut (6).

Inside the tap body (1) a solenoid valve (7) is included, through which the opening and closing of the tap itself is performed. Water enters the interior of the tap through the base (4), through 10 holes (8), for the passage to the corresponding internal ducts (9), which allow the circulation of water from the lower pallet or tap entrance through the exit (10), towards the pipe itself (2) already commented.

Seals (11) are provided in the tap for different chambers and in the internal cavity (12) established by the tap body (1), in addition to the solenoid valve (7), an electric generator (14) is located and a power supply battery (15), referring to (18) those that can be considered as the user's hands, which will remain in front of the tap and that through the sensor (16) are detected for tap operation.

Also, inside the faucet body, that is to say in its housing (12), a propeller or turbine (16) is placed facing one / more outlet holes (17), frontal or tangentially established in

According to these characteristics, the operation is as follows:

When the flow of water occurs, from the supply network, it strikes frontally or tangentially on the propeller or turbine (16), rotating it, which in turn drives the electric generator (14) associated with said turbine (16 ), producing electricity, usable for the operation of the solenoid valve (7) and to accumulate the excess energy in the electric battery (15), allowing to have that electric energy accumulated in the battery (15) for the next maneuver of the solenoid valve (7), and so on.

Therefore, when the sensor (13) detects the presence of the hands (18), the activation of the solenoid valve (7) is carried out, opening for the water to pass from the inlet base (4) towards the outlet pipe (2).

As it can be seen, the different complementary electronic components prevent the electric generator (14) from consuming electric current directly from the battery (15), which is previously charged in accordance with the aforementioned, being the stored current only usable to drive the solenoid valve (7), so that the actuation of this valve in the first maneuvers of use of the tap, until the electric generator (14) has been recharging the battery (15), is achieved with the electric charge that it provides, since it is a charged battery and therefore able to fill that lack in the first stage of recharging. That is to say that the first tap maneuvers are achieved by means of the charged battery (15)

When all the components inside the faucet go, it is vandal-proof, since including the sensor (13), there is no access other than the 5 diffuser or aerator (3), although for its disassembly it requires a tool

special.

The collection of the hands (18) by the presence sensor (13), will be carried out through the wall of the body (l) of the tap, all of it in such a way that all the aforementioned components are mounted by the part bottom and then closes with the base (4) that is threaded by means of the internal screws (5), and all this subject with the nut (6), being essential therefore to disassemble all the tap with respect to the sink or place of implantation of the same, to have access to the elements

15 inmates referred.

The tap, as is evident, will have the corresponding

conduits to be able to supply cold water and hot water, as well as a

mixing system, etc., for the versions of water mixer glyphs

20 (Cold / Hot).
