FILTER MANIFOLD

Description

BACKGROUND OF THE INVENTION

1. Field of Invention

[0001] The present invention relates to a filter manifold.

2. Description of Related Art

[0002] Figure 1 shows an installation that is known in the art, e.g., including a non-carbonated beverage dispenser, a soda dispenser, a coffee brewer that are arranged and coupled in relation to an ice maker, a combination of a water supply, a booster and a filter system and a carbonator pump. In the installation, the distance between the water booster and the filter system can be any length as space requires.

[0003] In operation, booster systems in the beverage market are designed to provide a water supply at a constant pressure, e.g., to carbonators, ice makers, non-carbonated drink dispensing valves, coffee/tea brewers, etc. In Figure 1, the typical booster system has the pump and the accumulator tank connected to the filter system that then distributes the water to the aforementioned devices. The current installation requires the pump and accumulator tank to be mounted separately from the filters or filtering system.

[0004] As one skilled in the art would appreciate, an accumulator tank is a water chamber which has a pre-pressurized internal air bladder. The accumulator tank is used to store water and dispense the water to reduce the cycling of the pump. There are many different types, kinds and styles of accumulator tanks on the market, e.g., see Figure 6. By way of example, components in a typical accumulator tank include a tank housing, a diaphragm arranged therein, fluid on one side of the diaphragm and pressured air on the other side of the diaphragm, an air nozzle for providing the pressured air, and a fluid nozzle for providing the fluid to/from the housing. When used with a pump to supply pressurized water, the accumulator tank may be installed in the pressured side of the pump to dampen water pressure spikes, reduce pump cycling, reduce pulsation in the line, help increase the pump's life and also save power.

[0005] In a reverse osmosis (RO) system, the accumulator/storage tank may be used to store pure water at some desired pressure until the pure water is used.

[0006] Some of the shortcomings of the above mentioned installation and devices include the following:
Currently, the booster systems are separately mounted from the filtering system through a series of multiple connections and hoses, see Figure 1. In effect, this means running tubing and manually plumbing the units in place. Each of these connections is a potential leak path for the overall system and any length of hose is prone to snagging, kinking, or rupture. Figure 4 shows a few of the many systems that are currently in the market for boosting water pressure, e.g., in Figs 4A through 4D. They are costly, bulky, and usually consist of many components. Repair and maintenance are complicated and often the entire unit must be replaced. See Figures 4 and 5 that show current configurations of pumps and filters, e.g., including Figs 5A through 5D.
Written state of the art can be found for example in US 2007/0045165 A1, which does show a reverse osmosis filtration system providing three cartridges as well as a storage tank. The storage tank for example is shown in figures 5 to 8 of US°2007/0045165 A1.
Moreover, US 2008/0135501 A1 shows to a reverse osmosis modular fluid treatment assembly whereas there are mounting brackets for several filter cartridges.
US 5,705,067 B describes a faucet with two water passages and a purification cartridge. It further describes a valve unit connecting or disconnecting the coldwater passage with the purification cartridge.
US 4,836,409 A refers to a pressure container assembly and especially to a diaphragm/liner structure adapted for mounting in a cylindrical tank.

SUMMARY OF THE INVENTION

[0007] The invention is set out in the appended set of claims. In summary, the present invention takes the form of a filter manifold. A cartridge style pump may be plumbed directly into the filter manifold. The pump can be configured as an intelligent pump, e.g., that would remove the need for an accumulator tank from the system. The connection would allow for direct porting and reduce line loss, and the requirement to remotely mount and plumb the boost system, as well as reduce potential leak paths.

[0008] A cartridge style accumulator tank may by plumped directly into a filter manifold, The connection allows for direct porting and reduces line loss, as well as reducing potential leak paths. The present invention is made up of two parts, a top cap (with bypass mode or without bypass (aka normal mode)) and an accumulator cartridge. The top cap may be installed into the line and then the accumulator cartridge is fastened into the top cap. To service the unit, there is no need to remove the top cap from the plumbing. To replace the cartridge without interrupting the system, one can activate the bypass mode by turning a handle on the top cap. This will also bleed the pressure from the cartridge allowing for the user to simply unfasten the cartridge from the line and replace with a new cartridge

DETAILED DESCRIPTION OF BEST MODE OF THE INVENTION

[0036] The present application builds on technology disclosed in U.S. Patent application 2017/0021293, which discloses embodiments related to a pump cartridge in relation to that shown Figures 1 through 5. The present application further develops this technology to include that shown in Figures 6-8 appended to this application.

Figures 1-5: Detailed Description of the Operation of the Present Invention:

[0037] In summary, the present invention may take the form of, or consist of, one or more pump cartridges, which are directly connected in-line with one or more filter cartridges. They may be paired with an accumulator tank for a pump version, and with no accumulator tank for a smart pump version. The inline mounting bracket design reduces the size of the system, the amount of connections, and the amount of hose required to install the system, which in turn reduces the space required for installation, the number of potential leak paths, and the likelihood of failure of the system due to issues with the hose. The reader is referred collectively to the embodiments shown in Figures 2A through 3.

Figures 2A and 2B: Beverage Applications

[0038] Consistent with that set forth above, Figure 1 show an overall view of the current known system, and Figure 2A show an overall view of a system generally indicated as 10 according to the present invention. In the current system shown in Figure 1, the booster system is mounted separately from the filtration system. In contrast, the system 10 according to the present invention shown in Figure 2A includes a combination generally indicated as 20 of cartridges for the pump, the accumulator tank, and the filter unit(s), which may be installed inline allowing for easier installation, maintenance, repair, and cartridge replacement.

[0039] Figures 2A, 2B and 2C show systems 20, 20' that may include the following:

#1) Pump cartridge (aka the motor pump unit cartridge) that may be configured or designed as a modular pump system arranged or contain in a standard cartridge housing, e.g., like that used for a filter cartridge. By way of example, the motor pump unit cartridge (#1) may be configured with porting, e.g., including input and output ports, that can be directly connected to corresponding ports in the filter systems in which it is implemented. By way of example, this motor pump unit cartridge (#1) may utilize a quick connect pump head that is known in the art and easily serviced. By way of example, see Figure 2D, the pump head (#9c1) that forms part of the motor pump unit (#9c) arranged or contained in the cartridge housing (#9).

#2) Accumulator cartridge that may be configured as, or would consist of, an accumulator tank designed to fit into the filter configuration of the filter systems in which it is implemented. By way of example, in an RO system 20' like that shown in Figure 2C, the accumulator tank (#2) may be after the filters (#3) as shown in Figure 2C.

#3) Typical filter cartridges that are known in the art, and available on the market. In effect, the scope of the invention is not intended to be limited to any particular type or kind of filter cartridge either now known or later developed in the future. Examples of the filter cartridge are disclosed in Figure 5 below, as well as the U.S. patent documents, and other references set forth below.

#4) Typical mounting brackets that are known in the art, and available on the market. In effect, the scope of the invention is not intended to be limited to any particular type or kind of mounting bracket either now known or later developed in the future. Examples of other mounting brackets are also disclosed in the U.S. patent documents, and other references set forth below.

#5) Porting that is configured for fluidicly coupling or connecting the pump cartridge (#1), the accumulator (#2) and the filter cartridge (#3) units together mounted in the mounting bracket (#4) that are known in the art. By way of example, such porting (#5) may form an integrate part of the mounting bracket (#4), including those currently available on the market.

[0040] Figures 2B and 2C shows combinations 20 and 20' of typical installations, e.g. using the pump and accumulator cartridges mounted in-line with one or more cartridges for the filter(s) for receiving and processing input fluid F_in and providing an output fluid F_out, F_out(RO). In Figure 2B, the combination includes a motor pump unit/cartridge (#1), an accumulator cartridge (#2) and one or more filter cartridges (#3), all configured in series and mounted on the inline mounting bracket (#4) for implementing in a beverage application like that shown in Figure 2A. In Figure 2C, the combination 20' includes the motor pump unit/cartridge (#1), the one or more filter cartridges (#3) and the accumulator cartridge (#2), all configured in series and mounted on the inline mounting bracket (#4) for implementing in a reverse osmosis (RO) application like that shown in Figure 2C.

[0041] In Figures 2A, 2B and 2C, the one or more filter cartridges (#3) may include typical filter cartridges for home or commercial use. The inline mounting bracket (#4) may include, or take the form of, a standard or known mounting bracket for filter installations. The inline mounting bracket (#4) may include the design porting (#5) coupling the motor pump unit/cartridge (#1) and the accumulator cartridge (#2) that matches a filter porting used for assembly and mounting.

[0042] Figure 2D shows the motor pump unit cartridge (#1) or (#6) that may be configured to include a cartridge housing (#9) having a motor pump mounting (#9a) that matches the filter cartridge mounting, and a motor pump porting (#9b) that matches the filter cartridge porting (#5) and a motor pump unit (#9c). By way of example, the motor pump unit (#9c) may include a pump head (#9c1) that has input/output porting to fit directly in line with, and couple to, the cartridge's porting (#9a) for matching and aligning with the design/filter porting (#5) of the existing filter cartridges like the one or more filter cartridges (#3). The motor pump unit (#9c) also includes a motor (#9c2) for driving the pump head (#9c1). The motor (#9c2) may also include a quick connect to allow for easier pump replacement as needed. It is important to note that the scope of the invention in not intended to be limited to any particular type or kind of motor and/or pump combination; and embodiment are envisioned, and the scope of the invention is intended to include, using a motor and/or pump combination that are now known or later developed in the future. By way of example, the motor and/or pump combination may include, or take the form of a motor and/or pump combination for implementing a diaphragm pumping arrangement, as well as other types or kind of pumping arrangement. The whole thrust of the present invention is to configured such a motor and/or pump combination in a standard cartridge like the cartridge housings used for the accumulator, the filter, etc., and to couple the motor and/or pump combination in the standard cartridge into the inline mounting bracket (#4), e.g., by using a standard cartridge mounting used for coupling the filter cartridge (#3) to the mounting bracket (#4), as well as a standard design porting (#5) for coupling the motor pump unit/cartridge (#1), the filter cartridge (#3) and the accumulator cartridge (#2) fluidicly together that matches the design/filter porting (#5) currently used for assembly and mounting.

[0043] By way of example, the following U.S. patent applications disclosure different types or kinds of pump technologies that may be suitably adapted, arranged or implemented, e.g., in a cartridge housing like element (#9) in Figure 2D. See U.S. Patent application numbers numbers 2016/0025086, 2016/0017882 and 2013/0309099. It is understood, and one skilled in the art would appreciate, that other U.S. patent applications may disclose other types or kinds of pump technologies that may be suitably adapted, arranged or implemented, e.g., in a cartridge housing like element (#9) in Figure 2D,

[0044] Figure 2E shows a filter cartridge that is disassembled and has a cartridge housing and a cartridge mounting cap; and Figure 2F shows the cartridge mounting cap in Figure 2E, having 1st and 2nd mounting cap ports. In Figure 2E, the housing cartridge has a filter arranged therein. The cartridge has a cartridge housing mounting end configured with housing mounting end threads, as best shown in Figure 2F. The cartridge mounting cap has cap threads, as shown in Figures 2E and 2F for coupling with the housing mounting end threads of the cartridge when the cartridge housing and the cartridge mounting cap are assembled or screwed together. The cartridge mounting cap has two portings coupled thereto. One porting maybe fluidicly coupled to the 1st mounting cap port, and the other porting maybe fluidicly coupled to the 2nd mounting cap port, as shown. The portings are also shown coupled to porting hosing for providing fluids to and from the portings and the cartridge assembly.

[0045] By way of example, and according to some embodiments of the present invention, the motor pump unit may be configured into the cartridge housing and its input/output pump porting suitably adapted or coupled to the 1st and 2nd mounting cap ports in order to implement the integration of such a motor pump unit into the inline pumping assembly and provide the inline pumping of fluid in the overall assembly, according to the present invention.

Figure 3: Pump Cartridge with Electronic Controls

[0046] Figure 3 shows a combination generally indicated as 30 that represents a similar concept, but rather than using an accumulator tank, the system 30 utilizes a motor pump unit generally indicated as (#6) with an intelligent controller, e.g., like electronic control module (#9c3) in Figure 2D. This feature will consist of a combination of a pump head, a motor and a controller, e.g., to provide constant flow and pressure to the system 30 among other pump control functionalities.

[0047] In effect, the pump cartridge (#6) with electronic control or controller (#9c3) may be configured to include, or consist of, the pump cartridge (#1) that also includes a controller module like element (#1c) in Figure 2D that may be configured to implement one or more pump control algorithms to perform or provide pump control functionality, e.g., consistent with that set forth below:
In close proximity, the pump cartridge (#6) with electronic controller (#9c3) may be configured to provide immediate response to system conditions.

[0048] By way of example, the system 30 may be configured to utilize pre-triggering to prevent instantaneous pressure drops, e.g., when valves are opened to dispense fluids. In this case, and by way of example, the pump cartridge (#6) with electronic controller (#9c3) may be configured to receive sensed signaling containing information, e.g., about instantaneous pressure drops, when valves are opened to dispense fluids, etc., and also configured to implement one or more suitable pump control algorithms to perform suitable pump control functionality to respond to the same.

[0049] By way of further example, the system 30 may be configured to utilize variable speed control to ensure that the flow and/or pressure remain constant to the need. As an example, a beverage dispense valve typically requires 275.79 kPA (40 PSI) to be supplied to the valve at a flow rate of 7.39×10^-5 m³/s (2.5 ounces) per second, with one valve open the pump may only require 25% of the power to meet that need. A typical pump without intelligence that is known in the art will still try to run at full speed using more energy and providing inconsistent flow as more valves are opened. In this case, and by way of example, the pump cartridge (#6) with electronic controller (#9c3) may be configured to receive sensed signaling containing information about speed, flow and/or pressure, etc., and also configured to implement one or more suitable pump control algorithms to perform suitable pump control functionality to respond to the same.

[0050] This system 30 may be configured to only use the power needed to provide the flow and pressure, e.g., by implementing suitable control or controller algorithms that forms part of the overall pump electronic control intelligence. In case where more valves may be open at the same time, the pump electronic control or controller may be configured to increase power as needed to maintain the required flow and pressure. Moreover, the pump pressure may be sensed using a pressure switch, transducer or other means of sensing pressure. The pump cartridge's electronic control or controller may be configured to monitor the pump and detect various operations such as, but not limited to, run dry, over current, over voltage, under voltage, etc., e.g., and implement suitable pump protection algorithms to protect the pump. By way of example, the pump protection algorithms may include, or take the form of, shutting the pump off, providing a suitable audio or visual warning, restarting the pump after a predetermined time increment, cycling the pump on/off, etc. In this case, and by way of example, the pump cartridge (#6) with electronic controller (#9c3) may be configured to receive sensed signaling containing information about power, voltage, current, speed, flow, valve openings, and/or pressure, etc., and also configured to implement one or more suitable pump control algorithms to perform suitable pump control functionality to respond to the same.

[0051] The system 30 may also be configured to utilize communications to alert the user of required maintenance or repair. This embodiment would eliminate the need for an accumulator tank as it would be on demand. In this case, and by way of example, the pump cartridge (#6) with electronic controller (#9c3) may be configured to receive sensed signaling containing information about maintenance, repair and/or alerts, etc., and also configured to implement one or more suitable pump control algorithms to perform suitable pump control functionality to respond to the same.

[0052] By way of example, the pump cartridge (#1) may include, or consists of, a pump head (#9c1) that has porting to fit directly in line with the existing filter cartridges like element (#3), a motor (#9c2) for driving the pump head (#9c1), and an intelligent electronic controller like element (#9c1) with the features listed above. The motor (#9c2) can also include a quick connect to allow for easier pump replacement as needed. Pump heads and motors are known in the art, and the scope of the invention is not intended to be limited to any particular type or kind thereof. By way of example, different types of pumps are known to have different types of pump heads, and different types of pumps are known to have different types of motors. One skilled in the art would appreciate and understand, without undue experimentation, how to implement a particular type of pump having a particular type of pump head in combination with a particular type of motor, without undue experimentation, for a particular type of application. By way of example, for a beverage application, one skilled in the art would appreciate and understand, without undue experimentation, how to implement one type of pump having one type of pump head in combination with one type of motor, without undue experimentation. Alternatively, and by way of further example, for a reverse osmosis application, one skilled in the art would appreciate and understand, without undue experimentation, how to implement another type of pump having another type of pump head in combination with another type of motor, without undue experimentation. Embodiments are envisioned, and the scope of the invention is intended to include, using the same type of pump having the same type of pump head in combination with the same type of motor, etc. In other words, the scope of the invention is not intended to be limited to the type of pump, the type of pump head, or type of motor used for any particular type of application.

[0053] Furthermore, one skilled in the art would appreciate and understand, without undue experimentation, how to implement one or more pump control algorithms to perform or provide the aforementioned pump control functionality, e.g., by using known microprocessor technology and suitable control algorithms and flowcharts.

Signal Processor or Processing Module

[0054] By way of example, a signal processor or processing module may be configured at least to:

receive signaling containing information about suitable sensed signaling; and

determine corresponding signaling containing information to implement predetermined or desired pump control functionality, based upon the sensed signaling received.

[0055] In operation, the signal processor or processing module may be configured to provide the corresponding signaling to control the system 30, e.g., to control the motor/pumping functionality.

[0056] By way of example, the signal processor or processing module may be configured in, or form part of, the electronic control or controller module.

[0057] By way of example, the functionality of the signal processor or processing module may be implemented using hardware, software, firmware, or a combination thereof. In a typical software implementation, the signal processor or processing module would include one or more microprocessor-based architectures having, e. g., at least one signal processor or microprocessor like element. One skilled in the art would be able to program with suitable program code such a microcontroller-based, or microprocessor-based, implementation to perform the functionality described herein without undue experimentation. For example, the signal processor or processing module may be configured, e.g., by one skilled in the art without undue experimentation, to receive the signaling containing information about the suitable sensed signaling for further processing, consistent with that disclosed herein.

[0058] Moreover, the signal processor or processing module may be configured, e.g., by one skilled in the art without undue experimentation, to determine the corresponding signaling containing information to implement the predetermined or desired pump control functionality, based upon the sensed signaling received, consistent with that disclosed herein.

[0059] The scope of the invention is not intended to be limited to any particular implementation using technology either now known or later developed in the future. The scope of the invention is intended to include implementing the functionality of the processors as stand-alone processor, signal processor, or signal processor module, as well as separate processor or processor modules, as well as some combination thereof.

[0060] The system may also include, e.g., other signal processor circuits or components, including random access memory or memory module (RAM) and/or read only memory (ROM), input/output devices and control, and data and address buses connecting the same, and/or at least one input processor and at least one output processor, e.g., which would be appreciate by a person skilled in the art.

Possible Applications:

[0061] Possible Applications may include one or more of the following: Beverage boost systems, or home booster/filters.

[0062] By way of example, and for the sake of understanding that disclosed herein, the present invention is described in relation to the beverage market and installation of such a system. By way of example, this disclosure also shows using only two filters mounted, but there can be as many as needed, as a one skilled in the art would appreciate.
