The present disclosure relates generally to water treatment and more specifically to water treatment systems for reducing water hardness.
Water softener or treatment systems are used to reduce concentrations of hard minerals in water supplies or the deposition of those hard minerals in the piping and fixtures through which water flows. The reduction of the hard minerals in the water can reduce scale build up and prolong the life of household appliances as well as industrial water systems.
In typical water treatment systems, the water supply may be introduced to a container or cartridge containing the water treatment material, such as softener salt. The water flows through the cartridge and contacts the water treatment material, which then reacts with hard minerals in the water to reduce the water hardness and prevent deposition on piping and fixtures.
Such water treatment systems may, however, cause the water treatment material itself to solidify if it sits stagnant for long periods of time. Once solidified in an aqueous environment, the water treatment material does not react as well with the water flowing through the system, reducing the effectiveness of the water treatment system. Therefore, it may be difficult to accurately and effectively treat the hard minerals without wasting large amounts of water treatment material.

These and other features of the present disclosure will become more apparent from the following description of the illustrative embodiments.
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings, and specific language will be used to describe the same.
A first embodiment of an illustrative water treatment system 10 for treating a water supply 20 with a water treatment solution 22 is shown in
The water treatment system 10 includes a tank 12, a dispenser 14, and a control system 16 as shown in
In typical water treatment systems, the water supply may be introduced to a container or cartridge containing the water treatment material, or citric acid. The water flows through the cartridge and contacts the water treatment material. As the water contacts the water treatment material, the water treatment material reacts with hard minerals in the water to reduce water hardness.
However, the reaction of the water treatment material with the hard minerals in the water may vary as the water flows through the cartridge thereby reducing the effectiveness of the water treatment material. For instance, the water treatment material may solidify or crystalize if the water treatment material stays stagnant for long periods of time, reducing its ability to dissolve and react with the water flowing through the system. As a result, the hardness of the water remains at high levels, and the solidified water treatment material needs to be replaced. Continually replacing the water treatment material may be expensive and wasteful.
To treat the water supply effectively and accurately, the present disclosure teaches the water treatment system 10 uses a doser 62 included in the system 10 to dose the water supply 20 with the water treatment solution 22. Unlike the other water treatment systems that introduce the water supply 20 to the water treatment material 24, the water treatment system 10 stores a water treatment solution 22 to be dosed into the water supply 20 as needed.
The tank 12 included in the system 10 stores the water treatment solution 22 and while the doser 62 doses a predetermined amount of the water treatment solution 22 into the water supply 20 so that the water treatment solution 22 reacts effectively with hard minerals. In this way, the hardness of the water supply 20 is better reduced compared to other water treatment systems.
For holding the water treatment solution 22, the tank 12 includes a tank housing 26 and a cartridge mount 28 as shown in
The cartridge mount 28 includes a gate 34 as shown in
To add the water treatment material 24 to the water in the storage reservoir 30, the dispenser 14 is configured to dispense the material 24 at the predetermined flow rate into the water contained in the storage reservoir 30. The dispensing of the water treatment material 24 may be important to effectively producing the water treatment solution 22. If the water treatment material 24 is added too quickly, the water treatment material 24 may conglomerate, not mixing properly with the water and forming deposits of crystalized material. The dispenser 14 dispenses the water treatment material 24 at the predetermined flow rate so that the water treatment material 24 will effectively dissolve in the water in the storage reservoir 30.
The dispenser 14 includes a cartridge 36, a cap 38, and a dispensing system 40 as shown in
The cartridge 36 includes a body 42 and a neck 44 as shown in
In the illustrative embodiment, the neck 44 is configured to couple to the cartridge mount 28 of the tank 12 as suggested in
The dispensing system 40 is configured to control the dispensing of the water treatment material 24 through the opening 48 in the neck 44 of the cartridge 36 at the predetermined flow rate. The dispensing system 40 controls the dispensing of the water treatment material 24 so that the addition of the water treatment material 24 to the water in the storage reservoir 30 is controlled over a predetermined time period. In this way, the water may not be over saturated with the water treatment material 24 too quickly. If the water treatment material 24 is added too quickly, the water treatment material 24 may conglomerate and form clumps in the solution, influencing the effectiveness of the solution 22 in treating the water supply 20.
In the illustrative embodiment, the dispensing system 40 includes an auger 52 and a knob 54 as shown in
The knob 54 is configured to be rotated by a user to cause the auger 52 to rotate about the axis 49. In this way, the auger 52 gathers predetermined amounts of the water treatment material 24 and transports the predetermined amounts of the water treatment material 24 through the opening 48 to dispense the water treatment material 24 at the predetermined flow rate in the storage reservoir 30.
The auger 52 includes a shaft 56 and a helical screw 58 as shown in
The helical screw 58 extends radially outward from and circumferentially around the outer surface 61 of the shaft 56 along at least part of the length of the shaft 56 as shown in
In the illustrative embodiment, the helical screw 58 extends along at least half the length of the shaft 56. In other embodiments, the helical screw 58 may extend more than or less than half the length of the shaft 56.
The helical screw 58 is shaped to define fins 63 as shown in
As the knob 54 is rotated by the user, the auger 52 is rotated causing the fins 63 of the helical screw 58 to move in the opening 48 and carry water treatment material 24 from the region 46 and move it across the opening 48. The spacing of the fins 63 along the axis 49 determines the predetermined amount of the water treatment material 24 dispensed with each rotation of the knob 54.
The control system 16 comprises the doser 62 in fluid communication with the storage reservoir 30 and the water supply 20 and a controller 64 coupled to the doser 62 as shown in
The doser 62 is configured to dose the predetermined amounts of water treatment solution 22 into the water supply 20 at varying flow rates based on a water flow rate through the doser 62. The doser 62 is configured to dose the predetermined amount of water treatment solution 22 at a first flow rate if the doser 62 determines the water is flowing through the doser 62 at a first water flow rate. If the water flow rate increases to a second water flow rate that is greater than the first water flow rate, the doser 62 is configured to proportionately increase the flow rate of dosing to a second flow rate. Conversely, if the water flow rate decreases to a third water flow rate that is less than the first and second water flow rates, the doser 62 is configured to proportionately decrease the flow rate of dosing to a third flow rate.
In this way, accurate and proportional amounts of the water treatment solution 22 may be added water supply 20 compared to other methods that introduce the water to the water treatment material 24. Injecting the water treatment solution 22 into the water flowing through the doser 62 based on the water flow rate may prevent the water supply 20 from becoming over or under saturated with the water treatment solution 22. In other embodiments, the doser 62 may be configured to determine a pH level of the water and vary the injection of the predetermined amount of water treatment solution 22 based on the measured pH level.
The control system 16 further includes a plurality of valves 66, 68, sensors 70, 72, a mixer 74, and a gate actuator 76 as shown in
The plurality of valves includes a first valve 66 in fluid communication with the water supply 20 and the storage reservoir 30 and a second valve 68 in fluid communication with the storage reservoir 30 and the doser 62 as shown in
In the illustrative embodiment, the first valve 66 is in fluid communication with a tank inlet conduit 65 as shown in
The controller 64 is configured to change the first valve 66 between an open position as shown in
In the illustrative embodiment, the second valve 68 in fluid communication between the doser 62 and dosing and flushing conduits 67, 69 as shown in
The second valve 68 is configured to change between a dosing position as shown in
The sensors 70, 72 include a level sensor 70 and a cartridge sensor 72 as shown in
The controller 64 is configured to direct the valves 66, 68 to change between their corresponding positions based on the feedback from the fill sensor 70. The controller 64 is configured to direct the first valve 66 to change between the open and closed positions to vary the flow of water into the storage reservoir 30 based on the fill level 30A-30E measured by the fill sensor 70. The controller 64 is configured to direct the second valve 68 to vary the flow path of the liquid between the dosing conduit 67 and the flushing conduit 69 to the doser 62 based on the fill level 30A-30E measured by the level sensor 70.
The controller 64 is coupled to the gate actuator 76 and the cartridge sensor 72. The controller 64 is configured to direct the gate actuator 76 to move the gate 34 to the open position if the cartridge sensor 72 detects the dispenser 14 is coupled to the cartridge mount 28 of the tank 12. Conversely, if the cartridge sensor 72 does not detect that the dispenser 14 is coupled to the cartridge mount 28, the controller 64 is configured to direct the gate actuator 76 to move the gate 34 to the closed position so as to block access through the tank opening 32. This prevents any of the material and/or liquid inside from contacting the user during refiling.
The system 10 is configured to operate in three different modes: a fill mode 1100 as shown in
The fill mode 1100 includes three stages: a first stage 1100A as shown in
The first predetermined fill level 30A corresponds to the storage reservoir 30 being at about 75% of its maximum volume. In the illustrative embodiment, the first predetermined fill level 30A is about 1.3 gallons or about 74% of a volume of the storage reservoir 30.
In the second stage 1100B of the fill mode 1100, the user is directed to replace the old empty dispenser 14 with a new full dispenser 14 containing the water treatment material 24, or citric acid powder to be added through the tank opening 32. To do so, the user removes the old empty dispenser 14 from the cartridge mount 28, which causes the cartridge sensor 72 to detect the dispenser 14 is no longer coupled to the cartridge mount 28. In response, the controller 64 directs the gate actuator 76 to move the gate 34 to the closed position.
The user then couples the new full dispenser 14 to the cartridge mount 28 for dispensing, which causes the cartridge sensor 72 to detect the dispenser 14 is coupled to the cartridge mount 28. In response, the controller 64 directs the gate actuator 76 to move the gate 34 to the open position so that the water treatment material 24 is ready to be dispensed.
In the third stage 11000 of the fill mode 1100, the user is directed to the add the water treatment material 24 to the storage reservoir 30 by rotating the knob 54 as shown in
Once the fill sensor 70 detects the second predetermined fill level 30B in the storage reservoir 30, the controller 64 indicates the system 10 is now in the treatment mode 11001B. The user is then directed to stop rotating the knob 54 of the dispensing system 40, and the controller 64 directs the system 10 to begin the treatment mode 1200.
In the treatment mode 1200, the controller 64 directs the mixer 74 to change form an off mode as shown in
The controller 64 directs the doser 62 to dose the predetermined amount of the water treatment solution 22 at a predetermined flow rate based on the water flow rate through the conduit 21. The doser 62 is configured to detect the water flow rate and to dose the predetermined amount of water treatment solution 22 a proportional flow rate based on the water flow rate. The doser 62 is configured to vary the dosing flow rate depending on changes of the water flow rate.
When the fill sensor 70 detects a third predetermined fill level 30C in the storage reservoir 30 that corresponds to the reservoir 30 being depleted or empty, the treatment mode 1200 is ended. The controller 64 then begins the flush mode 1300 as shown in
The flush mode 1300 includes two stages: a first stage 1300A and a second stage 1300B as shown in
The first valve 66 remains in the open position until the fill sensor 70 detects the first predetermined fill level 30A. Once the fill sensor 70 detects the first predetermined fill level 30A, the controller 64 directs the first valve 66 to change to the closed position, which triggers the second stage 1300B of the flush mode 1300.
In the second stage 1300B of the flush mode 1300B, as shown in
The second stage 1300B ends when the fill level sensor 70 detects the third predetermined fill level 30C. Once the third predetermined fill level 30C is detected, the controller 64 directs the second valve 68 to move to the dosing position and the user is signaled to begin the fill mode 1100.
In the illustrative embodiment, the control system 16 includes a user interface 77 as shown in
The user interface 77 includes an input system 78, an output system 79 coupled to the input system 78, and a communication unit 80 coupled to the input and output systems 78, 79 as shown in
The input system 78 is configured to provide the input from the user through a button, a sensor, combination thereof, or any suitable alternative. In the illustrative embodiment, the input system is a fill button 78B, which directs the controller 64 to begin the fill mode 1100 when the user presses the fill button 78. In other embodiments, the input system 78 may be an app for a smart device in which the user is able to control the system 10.
The output system 79 is configured to provide instructions or information to the user. The output system includes a set of fill level visual indicators 70A, 70B, 70C, 70D, a set of status visual indicators 79A, 79B, 79C, 79D, 79E, and a speaker 81 as shown in
The fill level visual indicators 70A, 70B, 70C, 70D are coupled with the fill level sensor 70 and configured to receive a signal from the sensor 70 corresponding to the fill level 30A-30E of the storage reservoir 30. Based on the fill level 30A-30E of the reservoir 30, the visual indicators 70A, 70B, 70C, 70D emit a light to indicate the fill level 30A-30E of the reservoir 30.
In the illustrative embodiment, the fill level visual indicators 70A, 70B, 70C, 70D include a first fill-level indicator 70A, a second fill-level indicator 70B, a third fill-level indicator 70C, and a fourth fill-level indicator 70D as shown in
The controller 64 is configured to direct the first fill-level indicator 70A to turn on when the fill level sensor 70 detects the second predetermined fill level 30B, i.e. 100% of the maximum volume of the storage reservoir 30. The controller 64 is configured to direct the first fill-level indicator 70A to turn off and the second fill-level indicator 70B to turn on when the fill level sensor 70 detects the first predetermined fill level 30A, i.e. 75% of the maximum volume of the storage reservoir 30. The controller 64 is configured to direct the second fill-level indicator 70B to turn off and the third fill-level indicator 70C to turn on when the fill level sensor 70 detects a fourth predetermined fill level 30D, i.e. 50% of the maximum volume of the storage reservoir 30. The controller 64 is configured to direct the third fill-level indicator 70C to turn off and the fourth fill-level indicator 70D to turn on when the fill level sensor 70 detects a fifth predetermined fill level 30E, i.e. 25% of the maximum volume of the storage reservoir 30.
When the controller 64 directs one of the fill level indicators 70A, 70B, 70C, 70D to turn on, the corresponding indicator 70A, 70B, 70C, 70D is configured to emit a light to the user. In some embodiments, the indicator 70A, 70B, 70C, 70D may emit a constant light. In other embodiments, the indicator 70A, 70B, 70C, 70D may emit a blinking light.
In some embodiments, the fill level indicators 70A, 70B, 70C, 70D may emit lights having the same color. In other embodiments, the fill level indicators 70A, 70B, 70C, 70D may emit lights that have different colors or some of the indicators 70A, 70B, 70C, 70D may be the same color while some of the others are different colors.
The status visual indicators 79A, 79B, 79C, 79D, 79E are coupled to the controller 64 and configured to indicate the stage of the system 10. The status visual indicators include a fill mode indicator 79A, an add powder indicator 79B, a treatment mode indicator 79C, a flush mode indicator 79D, and an empty indicator 79E as shown in
In the illustrative embodiment, the controller 64 directs each of the indicators 79A, 79B, 79C, 79D, 79E to emit a blinking light when turned on. In other embodiments, each of the indicators 79A, 79B, 79C, 79D, 79E is configured to emit a continuous light when directed to turn on by the controller 64.
In some embodiments, the indicators 79A, 79B, 79C, 79D, 79E may emit lights having the same color. In other embodiments, the indicators 79A, 79B, 79C, 79D, 79E may emit lights that have different colors or some of the indicators 79A, 79B, 79C, 79D, 79E may be the same color while some of the others are different colors.
The fill mode indicator 79A is configured to emit a light when the system 10 is in the fill mode 1100. After the user presses the fill button 78B, the controller 64 directs the fill mode indicator 79A to turn on, while the other indicators 79B, 79C, 79D, 79E are directed to remain off. As the system 10 enters the third stage 11000 of the fill mode 1100, the controller 64 directs the add powder indicator 79B to turn on along with the fill mode indicator 79A.
Once the fill mode 1100 is completed, the controller 64 directs the fill mode indicator 79A and the add powder indicator 79B to turn off and directs the treatment mode indicator 79C to turn on. The treatment mode indicator 79B remains on, until the fill sensor 70 detects the third predetermined fill level 30C and the flush mode 1300 is started.
Once the flush mode 1300 is started, the controller 64 directs the treatment mode indicator 79C to turn off and directs the flush mode indicator 79D to turn on. The flush mode 1300 is completed such that the third predetermined fill level 30C is again detected by the sensor 70. The detection of the third predetermined fill level 30C by the sensor 70 after the flush mode 1300 signals to the controller 64 to direct the flush mode indicator 79D to turn off and to direct the empty indicator 79E to turn on. Simultaneously, the controller 64 may direct the speaker 81 to emit an alarm or noise to signal to the user that the storage reservoir 30 is empty and that the fill mode 1100 needs to be initiated.
The communication unit 80 is coupled to the controller 64 and the input and output systems 78, 79 and is configured to use wireless signals to communicate with the user's smart phone, tablet, computer, or another suitable device. The wireless signals may BLUETOOTH®, Wi-Fi, or any other suitable alternative.
After the fill mode 1100 is completed and the fill level sensor 70 detects the second predetermined fill level 30B, the controller 64 is configured to direct the communication unit 80 to send a signal via Wi-Fi to the user's wireless device. The signal indicates, via a phone app or SMS notification, that the storage reservoir 30 is at a 100% fill level and that the treatment mode 1200 is in progress.
During the treatment mode 1200, as the water treatment solution 22 in the reservoir 30 depletes, the controller 64 is configured to direct the communication unit 80 to send signals via Wi-Fi to the user's wireless device indicating the new fill level in the reservoir 30.
The controller 64 is configured to direct the communication unit 80 to send a first signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 30 is at 100% of the maximum volume of the storage reservoir 30 when the fill level sensor 70 detects the second predetermined fill level. Simultaneously, the first fill-level indicator 70A is configured to turn on.
The controller 64 is configured to direct the communication unit 80 to send a second signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 30 is at 75% of the maximum volume of the storage reservoir 30 when the fill level sensor 70 detects the first predetermined fill level 30A. Simultaneously, the first fill-level indicator 70A turns off and the second fill-level indicator 70B is configured to turn on.
The controller 64 is configured to direct the communication unit 80 to send a third signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 30 is at 50% of the maximum volume of the storage reservoir 30 when the fill level sensor 70 detects the fourth predetermined fill level 30D. Simultaneously, the second fill-level indicator 70B turns off and the third fill-level indicator 70C is configured to turn on.
The controller 64 is configured to direct the communication unit 80 to send a fourth signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 30 is at 25% of the maximum volume of the storage reservoir 30 when the fill level sensor 70 detects the fifth predetermined fill level 30E. Simultaneously, the third fill-level indicator 70C turns off and the fourth fill-level indicator 70D is configured to turn on.
The controller 64 is configured to direct the communication unit 80 to send a fifth signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 30 is at 0% of the maximum volume of the storage reservoir 30 or empty when the fill level sensor 70 detects the third predetermined fill level 30C. The fifth signal also indicates that the flush mode 1300 is in progress and a new dispenser 14 is needed. In some embodiments, the controller 64 is configured to send the fifth signal to the company to indicate a new dispenser 14 should be sent to the user. Once the user is ready to begin the fill mode 1100, the steps are repeated to create more water treatment solution 22 in the storage reservoir 30.
In the illustrative embodiment, the tank 12, the dispenser 14, and the control system 16 are contained inside a system housing 18 included in the water treatment system 10. The system housing 18 mounts the user interface 77 of the control system 16 so that the user may easily access the user interface 77. The system housing 18 is also configured to limit the user's access to the tank 12.
The system housing 18 surrounds the tank 12, the dispenser 14, and the control system 16 as shown in
The water supply 20 is coupled to an inlet 23 and an outlet 25 of a conduit 21 included in the system housing 18. The doser 62 is coupled to conduit 21 downstream of the inlet 23. The water supply 20 flows through the inlet 23 of the conduit 21 through the doser 62 before flowing through the first valve 66. When in the closed position, the valve 66 directs the flow of water to the outlet 25 of the system 10.
In the illustrative embodiment, the mixer 74 is a hydraulic mixer that includes a stirrer 74A which extends into the storage reservoir 30 as shown in
During the fill mode 1100, the valve 66 changes to the open position and directs the flow of water into the storage reservoir 30. The valve 66 therefore blocks the flow of water through the mixer 74 to the outlet 25. Once the storage reservoir 30 is at the first predetermined fill level 30A, the valve 66 changes to the closed position and directs the flow of water to the outlet 25.
In the illustrative embodiment, the water treatment system 10 my further include a bypass conduit 27 as shown in
In the illustrative embodiment, the water treatment system 10 is coupled to a power supply 15. The power supply 15 may be included in the system 10 in some embodiments. The power supply 15 is configured to supply power to the different components of the system 10.
Another embodiment of a water treatment system 10 in accordance with the present disclosure is shown in
The water treatment system 210 includes a tank 212, a dispenser 214, and a control system 216 as shown in
The tank 212 includes a tank housing 226 and a cartridge mount 228 coupled to the tank housing 226 as shown in
The cartridge mount 228 is configured to receive the dispenser 214 as shown in
The cartridge mount 228 and the dispenser 214 are configured to change between a sealed configuration as shown in
The cartridge mount 228 includes a cartridge-mount housing 233, a gate 234, and a gate controller 235 as shown in
The gate 234 is in the closed position when the cartridge mount 228 and the dispenser 214 are in the sealed configuration as shown in
The gate 234 is in the open position when the cartridge mount 228 and the dispenser 214 are in the unsealed configuration as shown in
The cartridge-mount housing 233 includes a dispensing-system receiver 237 and a conduit 239 as shown in
In the illustrative embodiment, the cartridge-mount housing 233 further includes a grate 241 as shown in
The gate 234 is mounted in the passageway 232P of the conduit 239 to control the flow of the water treatment material 224 through the passageway 232P into the storage reservoir 230. In the illustrative embodiment, the gate 234 is a butterfly valve as shown in
The gate controller 235 includes a shaft 243, a gear 245, and a gear ring 247 as shown in
The gear ring 247 is configured to rotate about the cartridge axis 249 between a first position as shown in
The gear 245 if formed to define teeth 245T that mate with teeth 247T formed on the gear ring 247 so that movement of the gear ring 247 drives movement of the gear 245 as shown in
Conversely, rotation of the gear ring 247 about the cartridge axis 249 in a second direction, i.e. opposite to the first direction, from the second positon back to the first position causes the gear 245 to rotate about the axis 243A in a second rotational direction. The second rotational direction is opposite to the first rotational direction. Rotation of the gear 245 in the second rotational direction drives rotation of the shaft 243 to cause the gate 234 to change from the open position to the closed position.
In the illustrative embodiment, when the dispenser 214 is inserted into the dispensing-system receiver 237 of the cartridge-mount housing 233, the dispenser 214 engages the gear ring 247 of the gate controller 235. In this way, rotation of the dispenser 214 in either the first direction or the second direction causes the gear ring 247 to rotate about the cartridge axis 249.
For example, if the dispenser 214 is rotated in the first direction, the rotation of the dispenser 214 causes the gear ring 247 to rotate therewith in the first direction from the first position to the second position. This in turn, drives rotation of the gear 245, and thus the gate 234 about the axis 243A in the first rotational direction from the closed position to the open position.
If the dispenser 214 is rotated in the second direction, the rotation of the dispenser 214 causes the gear ring 247 to rotated therewith in the second direction from the second position to the first position. This in turn, drives rotation of the gear 245, and thus the gate 234 about the axis 243A in the second rotational direction from the open position to the closed position.
By linking the dispenser 214 to the gate controller 235, the transfer passageway 232P will be closed off by the gate 234 whenever the dispenser 214 is not inserted into the cartridge-mount housing 233. In this way, the user cannot access the storage reservoir 230. Additionally, the cartridge-mount hosing 233 and the gate controller 235 cooperate to block removal of the dispenser 214 from the dispensing-system receiver 237 when the gear ring 247 is in the second position. This prevents any of the material and/or liquid inside from contacting the user during refiling.
Turning again to the dispenser 214, the dispenser 214 includes a cartridge 236, a cap 238, and a dispensing system 240 as shown in
The cartridge 236 includes a body 242 and a neck 244 as shown in
The dispensing system 240 includes an upper valve 251 and a lower valve 253 as shown in
The upper and lower valves 251, 253 are each formed to include a plurality of openings 255, 257 as shown in
Normally, the upper and lower valves 251, 253 are fixed, or locked, relative to each other in a closed orientation as shown in
However, the lower valve 253 is configured to rotate relative to the upper valve 251, the cartridge 236, and the cap 238 about the cartridge axis 249 to an open orientation as shown in
To dispense the water treatment material 224, the cartridge 236 is inserted into the dispensing-system receiver 237 of the cartridge mount 228 as shown in
As discussed above, the dispenser 214 cooperates with the gate controller 235 of the cartridge mount 228 to control dispensing of the water treatment material 224 into the tank housing 226 as shown in
The upper valve 251 further includes a main body 282, engagement flanges 283, and spring arms 284 as shown in
In the illustrative embodiment, each spring arm 284 is formed to include a locking pin 284P that extends axially relative to the cartridge axis 249 as shown in
In the illustrative embodiment, the neck 244 of the cartridge 236 has notches 244N and the cap 238 has notches 238N for the engagement flanges 283 to extend through the cartridge 236 as shown in
The lower valve 253 further includes a planar body 286, alignment pins 287, and guide slots 288 as shown in
In the illustrative embodiment, each of the guide slots 288 has a counterbore 288B at one end of the guide slots 288 as shown in
In the illustrative embodiment, the locking pin 284P has two diameters as shown in
However, when the spring arm 284 is deflected from the locked position to the unlocked position, the portion of the locking pin 284P with the larger diameter D2 is moved out of the counterbore 288B and the portion of the locking pin 284 with smaller diameter D1 is in the guide slot 288. The dispensing system is thus free to change between the open and closed orientations.
The dispensing-system receiver 237 is shaped to include flange-receiving slots 290, alignment pinholes 291, and ribs 292 as shown in
The end of the cartridge 236 with the dispensing system 240 may be inserted in the cartridge mount 228 when the cartridge mount 228 and the dispenser 214 are in the sealed configuration. Before the dispensing system 240 is inserted in the cartridge mount 228, the lower valve 253 is locked relative to the upper valve 251 and blocked from rotating relative to the upper valve 251 as shown in
As the dispensing system 240 is inserted in the cartridge mount 228, the engagement flanges 283 extend into the flange-receiving slots 290 and the notches 247N as shown in
Additionally, the ribs 292 simultaneously extend into the spring-arm slots 288 as the dispensing system 240 is inserted in the cartridge mount 228 as shown in
In the illustrative embodiment, the flange-receiving slots 290 extend axially partway into the dispensing-system receiver 237 and circumferentially partway around the axis 249 as shown in
Then, when the cartridge 236 is rotated in the first direction, the engagement flanges 290 move along the circumferential portion 290C of the flange-receiving slots 290 as shown in
The control system 216 comprises a doser 262 in fluid communication with the storage reservoir 230 and the water supply 20 and a controller 264 coupled to the doser 262 as shown in
In the illustrative embodiment, the dosing line 267 has a protective housing 267H and a screen filter 267S as shown in
The control system 216 further includes an inlet valve 266, sensors 270, 272, a mixer 274, and a cartridge-mount lock 276 as shown in
In the illustrative embodiment, the control system 216 further includes a UV light 271 as shown in
In other embodiments, the control system 216 may not include a UV light 271. Depending on the concentration level of the water treatment solution 222, the UV light 271 may not be needed to kill in the storage reservoir 230. If a lower concentration of the water treatment solution 222 is used to dose the water supply 220, the UV light may be needed to kill microbes in the storage reservoir 230.
The sensors 270, 272 include level sensor 270 and a cartridge sensor 272 as shown in
In the illustrative embodiment, the cartridge sensor 272 is an RFID sensor. The dispenser 214 includes an RFID tag and the sensor 272 is configured to detect the RFID tag on the dispenser 214 to provide feedback to the controller 264 of when a new dispenser 214 is inserted into the cartridge mount 228.
In other embodiments, the cartridge sensor 272 may be another suitable sensor, such as a pressure sensor. The pressure sensor may be configured to detect the weight of the dispenser 214 in some embodiments. In other embodiments, the pressure sensor may be a spring/level system configured to depress/disengage in response to the weight of the dispenser 214 and allow the dispenser 214 to be rotated.
The level sensor 270 is configured to measure a plurality of fill levels of the tank 212 as shown in
The cartridge-mount lock 276 is coupled to the controller 264 and is configured to change between a locked position and an unlocked position based on the feedback from the cartridge sensor 272 as shown in
When the cartridge sensor 272 detects the RFID tag of the dispenser 214, the controller 264 directs the cartridge-mount lock 276 to change from the locked position to the unlocked position. In the unlocked position, the cartridge-mount lock 276 is spaced apart from the gate controller 235 so that gate controller 235 is free to rotate to allow a user to dispenser the water treatment material 224.
The inlet valve 266 is coupled to a tank inlet conduit 265 so that the valve 266 is in fluid communication with the water supply 220 and the storage reservoir 230 as shown in
The valve 266 is configured to control the flow of water to the fill conduit 265F and/or the flush conduit 269. The fill conduit 265F is unrestricted so as to quickly fill the storage reservoir 230 of the tank 212. The flush conduit 269 has a spray nozzle 269N so that when water is directed through the flush conduit 269 the water is sprayed by the nozzle 269N to flush the storage reservoir 230 of any residual water treatment solution 222 between refills of the tank 212.
The valve 266 is configured to change between a fully closed position, a fill position, and a flush position. In the fully closed position, the valve 266 blocks the flow of water through the fill conduit 265F and the flush conduit 269 to prevent water from being added to the storage reservoir 230 as shown in
In the illustrative embodiment, the inlet valve 266 is a solenoid valve 266. The controller 264 is configured to direct the valve 266 to change between the fully closed position, the fill position, and the flush position based on the mode of the system 210. The controller 264 is configured to direct the inlet valve 266 to change between the restricted, fill, and flush positions to vary the flow of water into the storage reservoir 30 based on the fill level 230A-230G measured by the fill sensor 270.
The system 210 is similar to the system 10 in
The fill mode 1100 includes three stages: a first stage 1100A as shown in
In the second stage 1100B of the fill mode 1100, the user is directed to replace the old empty dispenser 214 with a new full dispenser 214 containing the water treatment material 224, or citric acid powder to be added to the tank 212. To do so, the user may need to remove the old empty dispenser 214 from the cartridge mount 228. To remove the old empty dispenser 214 the cartridge 236 is rotated in the second direction to cause the gate controller 235 to move to the first position, which in turn causes the gate 234 to move to the closed position. Simultaneously, rotation of the cartridge 236 causes the dispensing system 240 to change to the closed orientation. When the gate controller 235 in the first position, the dispensing system 240 is free to be removed from the cartridge mount 228.
The user then inserts the new full dispenser 214 to the cartridge mount 228 for dispensing. To insert the dispenser 214 the user must align the alignment pins 287 with the alignment pinholes 291 in the dispensing-system receiver 237. This simultaneously aligns the engagement flanges 283 with the flange-receiving slots 290 so that the new full dispenser 214 may be inserted into the dispensing-system receiver 237 of the cartridge mount 228 as shown in
By inserting the dispenser 214, the cartridge sensor 272 determines if the dispenser 214 is coupled to the cartridge mount 228 by detecting the RFID tag of the dispenser 214. If the sensor 272 detects the RFID tag of the dispenser 214, the controller 264 directs the cartridge-mount lock 276 to move to the unlocked position so that the gate controller 235 is free to rotated so that the water treatment material 224 is ready to be dispensed.
In the third stage 11000 of the fill mode 1100, the user is directed to the add the water treatment material 224 to the storage reservoir 230 by the rotating the dispenser 214 to cause the cartridge mount 228 and the dispenser 214 to change from the sealed configuration to the unsealed configuration as shown in
Then, while still applying the downward axial force, the user rotates the dispenser 214 in the first direction as shown in
In the illustrative embodiment, the controller 264 directs the cartridge-mount lock 276 to move to the locked position so that the gate controller 235 is blocked from rotating thereby blocking rotation of the dispenser 214 while the water treatment material 224 is dispensed. In some embodiments, rotation of the dispenser 214 causes the cartridge-mount lock 276 to move back to the locked position thereby blocking rotation of the dispenser 214.
Once the water treatment material 224 is dispensed into the storage reservoir 230, the fill sensor 270 detects a second predetermined fill level 230B in the storage reservoir 30. In the illustrative embodiment, the dispenser 214 should be empty when the fill sensor 270 detects a second predetermined fill level 230B in the storage reservoir 230.
Once the fill sensor 270 detects the second predetermined fill level 230B in the storage reservoir 230, the controller 264 indicates the system 210 is in the fourth stage 1100D, or the mixing cycle of the file mode 1100 as shown in
In the illustrative embodiment, the mixer 274 includes a stirrer 274A which extends into the storage reservoir 230 as shown in
The controller 264 runs the fourth stage 1100D or the mixing cycle for a predetermined mixing period. In the illustrative embodiment, the predetermined mixing period is greater than or equal to about three minutes.
Once the fourth stage 1100D of the fill mode 1100 has completed, the controller 264 directs the cartridge-mount lock 276 to move to the unlocked position to release the dispenser 214 for removal and the controller 264 indicates the system 210 is now in the treatment mode 11001B. The user is then directed to remove the dispenser 214, and the controller 64 directs the system 10 to begin the treatment mode 1200.
In the treatment mode 1200, the controller 264 directs the doser 262 to dose the predetermined amount of the water treatment solution 222 into the water supply 220. The controller 264 directs the doser 262 to dose the predetermined amount of the water treatment solution 222 at a predetermined flow rate based on the water flow rate through the conduit 221. The doser 262 is configured to detect the water flow rate and to dose the predetermined amount of water treatment solution 222 a proportional flow rate based on the water flow rate. The doser 262 is configured to vary the dosing flow rate depending on changes of the water flow rate.
When the fill sensor 270 detects a third predetermined fill level 230C in the storage reservoir 230 that corresponds to the reservoir 230 being depleted or empty, the treatment mode 1200 is ended. The controller 264 then begins the flush mode 1300 as shown in
The flush mode 1300 includes two stages: a first stage 1300A and a second stage 1300B as shown in
The first valve 266 remains in the flush position until the fill sensor 270 detects a fourth predetermined fill level 230D. Once the fill sensor 270 detects the first predetermined fill level 30A, the controller 264 directs the first valve 266 to change to the fully closed position as shown in
In the second stage 1300B of the flush mode 1300B, as shown in
The second stage 1300B ends when the fill level sensor 270 detects the third predetermined fill level 230C. Once the third predetermined fill level 230C is detected, the controller 264 directs the valve 266 to the fill position to being refilling the tank 212, and the user is signaled to begin the fill mode 1100.
In the illustrative embodiment, the control system 216 includes a user interface 277 as shown in
The user interface 277 includes an input system 278 and an output system 279 coupled to the input system 278, and a communication unit 280 coupled to the input and output systems 278, 279 as shown in
In the illustrative embodiment, the user interface 277 includes a QR code 277Q as shown in
The input system 278 is configured to provide the input from the user through a button, a sensor, combination thereof, or any suitable alternative. In the illustrative embodiment, the input system is a fill button 278B, which directs the controller 264 to begin the fill mode 1100 when the user presses the fill button 278B. In other embodiments, the input system 278 may be a button on the app in which the user is able to control the system 210. In some embodiments, the fill button 278 is configured to emit a constant or flashing light.
The output system 279 is configured to provide instructions or information to the user. The output system 279 includes a set of fill level visual indicators 270A, 270B, 270C, 270D and a set of status visual indicators 279A, 279B, 279C, 279D, 279E as shown in
The fill level visual indicators 270A, 270B, 270C, 270D are configured to receive a signal from the sensor 270 corresponding to the fill level 230A-230E of the storage reservoir 230. Based on the fill level 30A-30E of the reservoir 230, the visual indicators 270A, 270B, 270C, 270D emit a light to indicate the fill level 30A-30E of the reservoir 30.
In the illustrative embodiment, the fill level visual indicators 270A, 270B, 270C, 270D include a first fill-level indicator 270A, a second fill-level indicator 270B, a third fill-level indicator 270C, and a fourth fill-level indicator 270D as shown in
The controller 264 is configured to direct the first fill-level indicator 270A to turn on when the fill level sensor 270 detects the second predetermined fill level 230B, i.e. 100% of the maximum volume of the storage reservoir 230. The controller 264 is configured to direct the first fill-level indicator 270A to turn off and the second fill-level indicator 270B to turn on when the fill level sensor 70 detects the a fifth predetermined fill level 230E, i.e. 75% of the maximum volume of the storage reservoir 230. The controller 264 is configured to direct the second fill-level indicator 270B to turn off and the third fill-level indicator 270C to turn on when the fill level sensor 270 detects a sixth predetermined fill level 230F, i.e. 50% of the maximum volume of the storage reservoir 30. The controller 264 is configured to direct the third fill-level indicator 270C to turn off and the fourth fill-level indicator 270D to turn on when the fill level sensor 270 detects a seventh predetermined fill level 230G, i.e. 25% of the maximum volume of the storage reservoir 30. The controller 264 is configured to alter the fourth fill-level indicator 270D when the fill level sensor detects the third predetermined fill level 230C, i.e. 0% of the maximum volume of the storage reservoir 230.
When the controller 264 directs one of the fill level indicators 270A, 270B, 270C, 270D to turn on, the corresponding indicator 270A, 270B, 270C, 270D is configured to emit a light to the user. In some embodiments, the indicator 270A, 270B, 270C, 270D may emit a constant light. In other embodiments, the indicator 270A, 270B, 270C, 270D may emit a blinking light. For instance, the fourth-level indicator 270D may change from a constant light to a blinking light when the controller 264 the fill level sensor 270 detects a change from the seventh predetermined fill level 230G to the third predetermined fill level 230C.
In some embodiments, the fill level indicators 270A, 270B, 270C, 270D may emit lights having the same color. In other embodiments, the fill level indicators 270A, 270B, 270C, 270D may emit lights that have different colors or some of the indicators 270A, 270B, 270C, 270D may be the same color while some of the others are different colors.
The status visual indicators 279A, 279B, 279C, 279D, 279E are coupled to the controller 264 and configured to indicate the stage of the system 10. The status visual indicators include a filling indicator 279A, an replace cartridge indicator 279B, a mixing indicator 279C, a treatment mode indicator 279D, and a flush mode indicator 279E as shown in
In the illustrative embodiment, the controller 264 directs each of the indicators 279A, 279B, 279C, 279D, 279E to emit a blinking light when turned on. In other embodiments, each of the indicators 279A, 279B, 279C, 279D, 279E is configured to emit a continuous light when directed to turn on by the controller 264.
In some embodiments, the indicators 279A, 279B, 279C, 279D, 279E may emit lights having the same color. In other embodiments, the indicators 279A, 279B, 279C, 279D, 279E may emit lights that have different colors or some of the indicators 279A, 279B, 279C, 279D, 279E may be the same color while some of the others are different colors.
After the user scans the QR code 277Q to set up the system 210, the communication unit may emit a sound to the user to indicate it is time to added a new dispenser 214. The user is prompted to press the fill button 278B as the fill button 278 emits a flashing light. Additionally, the app may send the user a notification to insert the new dispenser 214.
The filling indicator 279A is configured to emit a light when the system 210 is in the first stage 1100A of the fill mode 1100. After the user presses the fill button 278B, the controller 264 directs the fill mode indicator 279A to turn on, while the other indicators 279B, 279C, 279D, 279E are directed to remain off.
As the system 210 enters the third stage 11000 of the fill mode 1100, the controller 264 directs the replace cartridge indicator 279B to turn on and turns off the filling indicator 279A. The user then inserts the dispenser 214 into the cartridge mount 228 and the cartridge sensor 272 detects the RFID tag of the dispenser 214. The controller 264 then directs the cartridge-mount lock 276 to change to the unlock mode so that the user can rotate the dispenser 214 to dispenser the water treatment material 224.
Once the third stage 11000 of the fill mode 1100 is completed, the controller 264 directs the replace cartridge indicator 279B to turn off and directs the mixing indicator 279C to turn on. Once the fourth stage 1100D is complete, the controller 264 directs the mixing indicator 279C to turn off and directs the treatment mode indicator 279D to turn on. The treatment mode indicator 279D remains on, until the fill sensor 270 detects the third predetermined fill level 230C and the flush mode 1300 is started.
Once the flush mode 1300 is started, the controller 264 directs the treatment mode indicator 279D to turn off and directs the flush mode indicator 279E to turn on. The flush mode 1300 is completed such that the third predetermined fill level 230C is again detected by the sensor 270. The detection of the third predetermined fill level 230C by the sensor 270 after the flush mode 1300 signals to the controller 264 to direct the flush mode indicator 279E to turn off and to direct the fill button 278B to emit the flashing light. Simultaneously, the controller 264 may direct a speaker to emit an alarm or noise to signal to the user that the storage reservoir 230 is empty and that the fill mode 1100 needs to be initiated.
The communication unit 280 is coupled to the controller 264 and the input and output systems 278, 279 and is configured to use wireless signals to communicate with the user's smart phone, tablet, computer, or another suitable device. The wireless signals may BLUETOOTH®, Wi-Fi, or any other suitable alternative.
After the fill mode 1100 is completed and the fill level sensor 270 detects the second predetermined fill level 230B, the controller 264 is configured to direct the communication unit 280 to send a signal via Wi-Fi to the user's wireless device. The signal indicates, via a phone app or SMS notification, that the storage reservoir 230 is at a 100% fill level and that the treatment mode 1200 is in progress.
During the treatment mode 1200, as the water treatment solution 222 in the reservoir 230 depletes, the controller 264 is configured to direct the communication unit 280 to send signals via Wi-Fi to the user's wireless device indicating the new fill level in the reservoir 230.
The controller 264 is configured to direct the communication unit 280 to send a first signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 230 is at 100% of the maximum volume of the storage reservoir 230 when the fill level sensor 270 detects the second predetermined fill level. Simultaneously, the first fill-level indicator 270A is configured to turn on.
The controller 264 is configured to direct the communication unit 280 to send a second signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 230 is at 75% of the maximum volume of the storage reservoir 230 when the fill level sensor 70 detects the fifth predetermined fill level 230E. Simultaneously, the first fill-level indicator 270A turns off and the second fill-level indicator 270B is configured to turn on.
The controller 264 is configured to direct the communication unit 280 to send a third signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 230 is at 50% of the maximum volume of the storage reservoir 230 when the fill level sensor 270 detects the sixth predetermined fill level 230F. Simultaneously, the second fill-level indicator 270B turns off and the third fill-level indicator 270C is configured to turn on.
The controller 264 is configured to direct the communication unit 280 to send a fourth signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 230 is at 25% of the maximum volume of the storage reservoir 230 when the fill level sensor 270 detects the seventh predetermined fill level 230G. Simultaneously, the third fill-level indicator 270C turns off and the fourth fill-level indicator 270D is configured to turn on.
The controller 264 is configured to direct the communication unit 280 to send a fifth signal via Wi-Fi to the user's wireless device indicating that the storage reservoir 230 is at 0% of the maximum volume of the storage reservoir 230 or empty when the fill level sensor 270 detects the third predetermined fill level 230C. The fifth signal also indicates that the flush mode 1300 is in progress and a new dispenser 214 is needed. In some embodiments, the controller 264 is configured to send the fifth signal to the company to indicate a new dispenser 214 should be sent to the user. Once the user is ready to begin the fill mode 1100, the steps are repeated to create more water treatment solution 222 in the storage reservoir 230.
