Abstract
Description
- The invention concerns a device for the automatic delivery of water able to be employed in electronically controlled taps wherein delivery is commanded, substantially automatically, through sensor means which detect the presence of the user.
- The state of the art includes monocommand mixer taps comprising a mixer cartridge, located inside the monoblock of the tap, associated with a lever, which allows to regulate both the mixing and the delivery of the water, and which is mounted above the monoblock.
- The state of the art also includes taps of the electronic type wherein the water is delivered substantially automatically when the user approaches the taps.
- Such taps comprise a valve provided with interception means cooperating with a solenoid device, or with an electric motor, able to command the opening and closing thereof, respectively to deliver and interrupt the flow of water; the solenoid device or the motor is activated by appropriate sensor means able to detect the presence of the user.
- In some embodiments, the valve is associated with manual activation means which allow to regulate the mix of hot and cold water.
- The structure of this type of valve and the need to feed the solenoid device or drive motor of the interception means electrically make it necessary to locate the valve and the electric and electronic components in the lower part of the monoblock, or cast block, of the tap, which therefore must be appropriately sized.
- This means that it is necessary to design and make specific monoblocks for the electronically controlled taps, that is, different from those for monocommand mixer taps, with greater problems in terms of planning the production and managing stocks.
- Moreover, the greater size of the monoblock considerably limits the design and aesthetics of the tap.
- Furthermore, the presence of electric and electronic parts inside the monoblock in the zone where the water passes can cause malfunctions of the tap and can compromise the safety of the user.
- The present Applicant has devised and embodied this invention to overcome these shortcomings and to obtain further advantages.
- The invention is set forth and characterized in the main claim, while the dependent claims describe other characteristics of the invention.
- The purpose of the invention is to achieve a device for the automatic delivery of water, which can be associated with a monoblock for mixer taps of a substantially standardized type, that is, of the type for monocommand mixer taps, thus obviating the need to produce a specific monoblock for electronically controlled mixer taps.
- Another purpose of the invention is to achieve a device for the automatic delivery of water which is practical, functional and compact and can be used in conditions of absolute safety for the user.
- The device according to the invention comprises a mixer cartridge, able to be arranged inside a monoblock for mixer taps of a conventional type, means to regulate the mixing of water and actuation means, commanded electrically, which can be associated with the monoblock from the above and able to cause the flow of water to open and close by acting on an interception element of the mixer cartridge.
- The actuation means cooperate with a sensor able to detect the presence of the user and to automatically determine the activation of said actuation means.
- In a preferential embodiment of the invention, the actuation means are driven by a member powered by batteries.
- In one embodiment, the means to regulate the mixing, the actuation means and the electric and electronic components connected thereto are integrated into a single block able to be coupled on the mixer cartridge in a position outside the monoblock.
- The device according to the invention is therefore able to be associated with monoblocks for monocommand mixer taps and thus allows to obviate both the problem of stylistic limitations and design imposed by the devices for electronically controlled taps, and also the problem of production and storage of different types of monoblock.
- The separation of the electric and electronic parts from the mixer cartridge confers characteristics of extreme safety and functionality on the device according to the invention.

distributor element 18 is associated by having the same shape above themovable platelet 17 and is therefore able to rotate solidly therewith. - The
distributor element 18 comprises a central aperture, or discharge oroutlet aperture 18 a, communicating with thehole 17 a and aperipheral aperture 18 b communicating with theeyelet 17 b. -
Sealing elements bottom 14 and the supportingbase 22, between thebottom 14 and the fixedplatelet 16 and between themovable platelet 17 and thedistributor element 18. - The
drawing element 19 is coupled axially with thedistributor element 18 and defines aninner chamber 26 therewith. - The upper part of the
drawing element 19 protrudes with respect to the containingbody 13 and has a knurling 27 on the perimeter and, at the center, acavity 28 opening upwards. - The
cavity 28 communicates with thechamber 26 by means of afirst channel 29 and with thecentral aperture 18 a by means of asecond channel 31 made partly on thedistributor element 18 and partly on thedrawing element 19. - The
membrane 20 is housed on the bottom of thechamber 26 and is peripherally constrained between thedrawing element 19 and thedistributor element 18; it has anextension 20 a on the lower part which in its normal condition, that is, when thetap 12 is closed, closes thecentral aperture 18 a. - The
membrane 20 is also provided with a small throughhole 32 located in correspondence with theperipheral aperture 18 b and able to make the latter communicate with thechamber 26. - The command and
regulation unit 40 comprises abase 33 and ahandle 45, which can be solidly associated with the latter and is hollow inside, able to contain: adrive member 41 provided with apiston 42,feeder batteries 36 and anelectronic circuit 43. - The
base 33 is provided with a plurality of columns 34 (in this case five) on which aplate 35 is able to be engaged and attached by means ofscrews 37. - The
base 33 is also provided at the center with ahole 49 on the inner wall of which there is a knurling 50 able to couple with the knurling 27 of thedrawing element 19. - The
base 33 and theplate 35 define theseating 39 for thedrive member 41 at the center and, on the periphery,seatings 38 for thebatteries 36. - The
drive member 41, which can consist of a solenoid device or an electric motor, is fed by thebatteries 36 and comprises anextension 41 a able to be constrained to the inside of thecavity 28. - The
extension 41 a is provided at the lower part with aseating 51, the function of which is to connect thechannels - The
drive member 41 is able to move thepiston 42 axially, permitting it to be selectively inserted into thefirst channel 29. - To be more exact, the
piston 42 is able to be taken from an extracted position, wherein it closes thefirst channel 29, to a retracted position, wherein it leaves the latter free. - According to a variant, the
piston 42 is able to close only, or also, thesecond channel 31. - The
electronic circuit 43 mounted on theplate 35 is able to manage thedrive member 41 according to what is detected by apresence sensor 44 associated therewith. Thesensor 44 is closed at the upper part by acover 46 associated with thehandle 45 by means of asealing ring 47. - In the assembled condition of the
device 10, the command andregulation unit 40 is mounted above themixer cartridge 30, and in a position outside themonoblock 11, due to the coupling between the knurling 27 of thedrawing element 19 and the knurling 50 of thebase 33. The stability of this coupling is ensured by the presence of anelastic clamping ring 48 which prevents the command andregulation unit 40 from coming off. - The
device 10 as described heretofore functions as follows. - When there is nobody near the
tap 12, thedrive member 41 is inactive and has thepiston 42 in the extracted position, that is, closing thefirst channel 29. - In this condition, the
chamber 26 is in communication with theperipheral aperture 18 b only. - The water arriving from the pipes of the water system therefore rises from the
peripheral aperture 18 b, through the throughhole 32, into thechamber 26, compressing themembrane 20 which closes thecentral aperture 18 a and therefore prevents the water from flowing towards thedelivery outlet 21. - When the user approaches the
tap 12, thesensor 44 detects the presence and, through theelectronic circuit 43, causes the activation of thedrive member 41 which takes thepiston 42 to the retracted position, leaving thefirst channel 29 free which is therefore in communication with thesecond channel 31 and with thecentral aperture 18 a. - In this condition the pressure inside the
chamber 26 is substantially atmospheric pressure, therefore the water under pressure arriving from theperipheral aperture 18 b raises themembrane 20 which frees thecentral aperture 18 a, allowing the water to pass and flow towards thedelivery outlet 21 through theholes - When the user moves away from the
tap 12, thesensor 44, no longer detecting any presence, causes the de-activation of thedrive member 41 which takes thepiston 42 to the extracted position wherein thetap 12 is closed. - According to a variant, a timer is associated with the
electronic circuit 43 and is able to de-activate thedrive member 41 after a pre-determined time, which can be programmed as desired, from its activation. - The temperature of the water delivered can be regulated by making the
handle 45 rotate, which, being constrained to thedrawing element 19, causes a mating movement of the latter and hence of thedistributor element 18 and themovable platelet 17. - To be more exact, the rotation of the
movable platelet 17 causes the displacement of theeyelet 17 b with respect to theholes - It is obvious however that modifications and/or additions can be made to the
device 10 as described heretofore, but these shall remain within the field and scope of the invention. - For example, the
mixer cartridge 30 can have different components from those shown and described here and the bottom 14 can be replaced by another, functionally equivalent element. - Or the
plate 35 can be attached to thecolumns 34 in a different way, for example by clamping pins, instead of thescrews 37. It is also obvious that, although the invention has been described with reference to specific examples, a person of skill shall certainly be able to achieve many other equivalent forms of the device for the automatic delivery of water, all of which shall come within the field and scope of the invention. - It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
