    [0001] BACKGROUND OF THE INVENTION The present invention generally relates to water filtration systems, particularly such systems installed in the vicinity of conventional water faucets. Water filter systems mounted at the outlet of a conventional faucet are known. A replaceable cartridge is placed in a case, also mounted on the spout of the tap. These systems, however, are considered ugly because of the large cartridge case mounted on the spout. In addition, the volume of the cartridges of these systems is relatively small, and the cartridges must be replaced frequently. Water filter systems making use of under-the-bench cartridges are also known. These systems are more aesthetic, but generally require a separate faucet. Many traditional sinks lack an access opening for the installation of a separate faucet, and consumers often use an auxiliary opening in their sink to install a soap dispenser. As a result, the mounting of these filter systems often involves the creation of a designated hole in the sink flange. These openings are difficult to drill, as the sink is made of stainless steel, or other hard-to-drill materials using traditional tools. In addition, these systems displease users, who prefer to avoid the installation of a separate faucet. - 2 - Other sink-mounted filter systems require complex plumbing fittings in the valve escutcheon plate, which are complicated to mount, install, and maintain. Remote control systems have been created for water flow control for home power supply, but these systems require connection to the main home electronics. Accordingly, there is a need for the creation of an improved water filter system capable of overcoming the disadvantages of the aforementioned conventional systems.
    [0002] SUMMARY The above identified requirement is met by the present water filter system installed beneath the worktop, presenting to the user a remotely controlled system control capability without the need for installation. and / or the use of a separate faucet in an installed sink, meets the requirement identified above. In addition, the installation of the present system is more convenient because the control manifold connects directly, and easily, into the water supply line and into a water inlet duct. using traditional threaded fittings. The manifold selectively connects a filter apparatus to the water supply line and then to the faucet using an electronic valve controlled by a remote controller. Thus, the tap spout emits filtered or unfiltered water, depending on the activation of the remote control controller. To facilitate the task for the user, the remote control is devoid of any structural connection to the manifold, the various pipes, or the tap. According to another characteristic of the present system, the regulator is activated only when the water flows through the collector. In the preferred embodiment, the collector is provided with indicators providing the user with information about the state of the system.

DETAILED DESCRIPTION Referring to FIGS. 1 and 2, the present remote control water filter system (which is a tap filter system) is generally designated by the reference numeral 10, and shown mounted under a control plane. traditional work 12, carrying a valve 14 having hot and cold water controls, 16, 18 respectively, and a spout 20 (which is a spout). In the present application, the term "water filtering system" refers to any of the treatment systems known to improve the taste, purity or content of the water brought into the home or a commercial establishment. Water filtration systems include, but are not limited to, carbon filters, reverse osmosis systems, UV treatment systems, softeners, fiber filters or the like. The faucet is shown mounted in a location adjacent to a sink 22, with a discharge 24, in the manner known in the prior art. A hot water supply pipe 26 is connected between the hot water regulator 16 and a shut-off valve 28, and a cold water supply pipe 30 is connected between the hot water regulator 18 and a hot water supply pipe 18. Corresponding cold water shutoff valve 32. The two valves 28, 32 are connected to a water supply pipe or a corresponding water supply pipe 34 known in the prior art. The present remote control water filter system 10 includes a control manifold 36 connected between one of the hot and cold water shutoff valves 28, 32 and the corresponding water supply line 26, 30. Preferably, the manifold 36 is connected to the cold water system, and this manifold is in fluid communication with the cold water supply line 30, also referred to as the inlet conduit of the valve. In the present application, "manifold" refers to any type of fluid connector, having a bypass device function, including, but not limited to, unitary packages (as shown herein) as well as independent valves. and separate components, connected together with tubes, pipes, or other flow lines. According to the detailed description below, this connection is preferably made using traditional threaded connections, in order to facilitate its assembly by a user, for example an individual at home. The system 10 also includes a filtering apparatus generally designated by the reference numeral 38, preferably also under the worktop 12. For the purpose of this application, the filter apparatus 38, similar to the system The water filter described above is contemplated as any conventional drinking water treatment apparatus, including, but not limited to, carbon shot filters, osmosis systems, and the like. reverse, a UV treatment system, or other. The filter apparatus 38 is in fluid communication with the manifold 36 via a fluid inlet conduit 40 and a fluid outlet conduit 42. In accordance with the prior art, the conduits 40, 42 are designed as flexible tubes made of a suitable material for conveying treated drinking water. A remote control 44 is shown placed on the top of the worktop 12, in close proximity to the valve 14. It should be understood that the regulator 44 is not structurally connected to the valve 14, the manifold 36, the apparatus filter 38, or any of the corresponding lines. On the other hand, regulator 44 provides wireless control of system 10, preferably by RF signals, which will be described in more detail below.
    [0009] An important feature of the present system is that the remote control 44 (which is a wireless controller) controls components of the manifold 36, so that the manifold provides selective fluid communication between the water supply line 34 and the manifold 36. In other words, the activation of the regulator 44 offers the user the possibility of determining whether unfiltered or filtered water is dispensed through the spout 20 of the spigot (through a common path in said spout). tap (20)). In Fig. 1, a standard flow path is represented by a dotted line, in which the potable water flows through the manifold 36, through the inlet conduit of the valve 30, at the tap 14. In FIG. 2, the regulator 44 is activated by the user, and causes the closure of an internal valve in the manifold 36, directing the flow of the supply pipe through the filtering apparatus 38, and then its return to the manifold and, finally, the valve 14, where it is emitted by the nozzle 20. Turning now to Figures 3 to 5, the structure of the regulating collector 36 is illustrated in more detail. A main manifold housing 46 defines a first passage 48 for providing fluid communication between the water supply conduit 34 and the valve inlet conduit 30, thereby bypassing the filter apparatus 38. At least a valve actuated remotely or. remote control 50, preferably an electronic or equivalent solenoid valve, is associated with the manifold 36, and placed in fluid communication with the first passage 48 in a first position, or open position, as shown in FIG. 3. In accordance with the description In more detail below, each valve 50 is constructed and arranged for regulating, preferably bypassing, the flow of water in the manifold 36 so that it flows to the filter apparatus 38 when desires filtered water.
    [0010] Thus, in a default operational configuration, untreated drinking water flows as described in line "F" from the water supply line 34, through the shutoff valve 32 (which is a valve stop valve, and could be a stop valve of the supply of water), then in the first passage 48. A flow controller 52 is disposed in the first passage 48 downstream of the valve 50, and electronically connected to the regulator 44, so that the valve can be activated in a second closed position only when water flows into the first passage and out of the manifold 36 to the valve 14 In the present application, the term "flow controller" is intended to mean any type of flow sensor emitting an electronic signal upon detection of a fluid flow, including, but not limited to, magnetic switches, turbines, and the like. , pressure transducers n or other. Although other switches may be envisaged, in accordance with the prior art, the present flow controller 52 is a 0.5 gpm model with a magnet inside the manifold 36, and a magnetic switch external to the collector for detecting when the valve 14 is open and the water flows through the spout 20.
    [0011] At each end of the first passage 48, the module housing 46 is provided with a connector to facilitate connection of the present system 10 to an existing water supply system. In the preferred embodiment, the sleeves are threaded and compatible with existing traditional plumbing fittings for water supply, but further connections may be envisaged, including push-fit, bayonet, or other connecting technologies. equivalent. A first connector, or connector for the water supply, 54, will preferably be a female thread type connector engaging a tip of the stop valve 32. At the other end of the passage 48, a second connector 56 (which is a valve fitting), is preferably a male thread type connector, for connection to the inlet line of the valve 30; it is usually a standard fitting found in most hardware stores or hardware stores. Another feature of the present system 10 is that the connectors 54, 56 represent the only fluid connection between the manifold 36 and the valve 14. In addition, the connectors 54, 56, particularly the connector 54, are the only structural supports of the manifold In Referring now to FIG. 4, when the valve 50 is activated by the regulator 44, it is moved to a second position, namely a closed position, in which the water flows from the first connector 54 in a second passage 58 of the manifold 36, thereby providing fluid communication between the water supply line and the filter apparatus 38. More specifically, the second passage 58 includes a sleeve 60 configured for connection on one end of the inlet duct of the filter 40, and a sleeve 62 configured for connection to one end of the outlet duct of the filter 42. The second sleeve 62 is then connected to a third passage 64, which directs filtered water into the first passage 48, passing through the flow controller 52, the inlet of the valve 30, and, finally, the valve 14. In the preferred embodiment, a The check valve 66 is connected in the third passage 64, between the sleeve 62 and the flow controller 52, to prevent backflow of untreated water into the filter apparatus 38. Although the check valve 66 is shown as being integrated in the regulation manifold 36, it should be specified that it can be connected separately in the flow path of the water, or placed elsewhere in the system 10, provided that is ensured the function described above. Thus, depending on the position of the valve 50 between the first and second positions, the system 10 is configured so that the valve 14 emits filtered or unfiltered water through the spout 20, through the same path. 'flow. The same nozzle 20 thus emits filtered or unfiltered water, depending on the position of the valve 50.
    [0012] Referring now to FIG. 5, in the event of failure of the solenoid valve 50, the latter then remaining in its closed position, or second position, in FIG. 4, the user benefits from the option actuating a manual bypass to provide fluid flow through the first passage 48. An additional manual bypass valve 68 is connected to the first passage 48, and when opened, the valve creates a flow path which passes through the valve 50 and up to the inlet 30 of the valve. In Figs. 6-9, regulator 44 is described in more detail. A frustoconical ring of the regulator 70 is optional, and snap-fitted to a similarly shaped casing 72 (which is a return-regulated regulator casing) defining an internal chamber 74 (which is an interior chamber). The housing snaps onto a flexible base 76, which seals the chamber 74 against the introduction of any undesirable moisture. A flange 78, relatively rigid, has at least one indicator opening 79 made and arranged to transmit the light passing through a diffuser 80 receiving light from a series of light-emitting diodes 81 located on a circuit board. The diffuser 80 adjusts the lateral projection of the light so that the user can read the individual light-emitting diodes 81 more easily. Also located on the printed circuit board 82 is an RF transmitter, well known in the art. the technique, and a push button 84 (defining a button and an on / off switch) engaging a battery pack 86. The battery pack 86 is constructed and arranged to house at least one, and preferably two, batteries. replaceable or rechargeable 88 for powering the system 10. A plurality of protuberances 90 protrude vertically from the housing 86 to the printed circuit board 8 2, and serve as locating points for biasing members 92, preferably helical springs or the like.
    [0013] When the user presses on the housing of the regulator 72, the disc 78, the diffuser 80 and the printed circuit board 82 mutually move in a single block against the force of the return elements 92, as well as relative to the base 76, and cause the switch 84 to close against the battery case 86. When the switch 84 is closed, an RF signal is transmitted to the collector 36 to move the valve 50 to the second position to allow the flow of water in the filter apparatus 38, and thence to the valve spout 20. Although the present description relates to a certain preferred remote control, it should be noted that the remote control 44 may be provided in other embodiments with user-controlled operation through a control signal from valve 50. These alternative controllers include, but are not limited to, mobile phones or other computers in wireless capability, portable or non-portable, voice activated devices, motion activated devices, optical sensors, capacitive sensor devices, and similar technologies. Referring now to FIG. 10, the manifold 36 is preferably closed in a housing 94 having a second printed circuit board 96, and a display board of the state 98. The parameters state, although not limited to, include filter life, errors, signals, normal functional state, or other. It is contemplated that the printed circuit board and the valve 50 will be powered with a designated power source 100, for example a battery pack, but the standard household wall outlet power supply is also contemplated. The printed circuit board 96 includes a control of the valve, schematically illustrated as 102. The printed circuit board 96, and, more specifically, the control of the valve 102, is activated by the flow controller, and connected to the valve 50, to enable the latter to be energized upon activation of the button 78 on the regulator 44. The system 10 is configured so that the valve returns to the first position, by default, of FIG. from the second position, when the user once again operates the regulator 44, or if the flow of water has been turned off at the tap 14. Although some realization of the present system for remote control tap filter have been illustrated and described, those skilled in this art will understand that certain modifications can be made to this system without departing from the invention in its more general, presented and specific aspects. cified in the following claims.
