Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the present invention and are not intended to limit the invention to the particular embodiments described herein. Based on the embodiments of the present invention described in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a drinking water supply apparatus, including: mineral tank 10, mineral feed line 11, clean water line 26, and a controller.
The inlet end of the mineral conveying pipeline 11 is connected to the mineral tank 10, and the mineral tank 10 is used for storing mineral concentrate. The outlet end of the mineral conveying pipeline 11 is used for connecting to a water taking device (such as a water tap 30 in the figure). A mineral feed line 11 delivers mineral concentrate from the mineral tank 10 to a water intake. The mineral conveying pipeline 11 is provided with a first electromagnetic valve 13 and a liquid pump 12. The draw pump 12 is used to pump mineral concentrate.
A filter element 20 is arranged on the clean water line 26. The inlet end of the clear water line 26 may be connected to a water source, such as a tap water line. The water outlet end of the clear water line 26 is adapted to be connected to a water intake device (e.g., a faucet 30 in fig. 1). The cartridge 20 filters water from a water source.
The controller is electrically connected to the first electromagnetic valve 13, and the controller controls the first electromagnetic valve 13 to be opened in a pulse mode according to the preset mixed concentration. And, the controller controls the operation of the liquid-extracting pump 12 while the first electromagnetic valve 13 is opened. Alternatively, the controller may control the pumping pump 12 to operate only during the period when the first solenoid valve 13 is opened. Alternatively, the controller may control the liquid pump 12 to operate at all times regardless of whether the first solenoid valve 13 is open. The power of the draw pump 12 is low due to the low flow rate of the mineral concentrate, and the draw pump 12 is typically a centrifugal pump, so that the life of the draw pump 12 is not significantly affected even if it is operated with the first solenoid valve 13 closed. During the opening of the first solenoid valve 13, the mineral feed line 11 feeds mineral concentrate from the mineral tank 10 to the water intake. At the same time, the controller controls the clean water line 26 to prepare clean water, which is mixed with the mineral concentrate at the water intake.
The predetermined mixed concentration may be set by the user on demand. Alternatively, several mixed concentrations may be set at the time of shipment, and a user may select one of the several mixed concentrations as a predetermined mixed concentration as needed. In one embodiment, the flow rate of the mineral concentrate supplied by the mineral delivery line 11 and the flow rate of the purified water supplied by the purified water line 26 may be factory set and stored in the controller. In another embodiment, flow meters may be provided in the mineral delivery line 11 and the purified water line 26 to obtain the flow rate of the mineral concentrate and the flow rate of the purified water, respectively. Thus, in the case where the flow rate of the mineral concentrate and the flow rate of the purified water are known, the predetermined mixture concentration is mainly determined by the total duration of the pulsed opening of the first electromagnetic valve 13. Specifically, the controller may adjust the duty cycle of the pulses to adjust the length of time that the first solenoid valve 13 is open during each cycle, thereby controlling the delivery of mineral concentrate. Furthermore, by setting the period of the pulses to be small, it is possible to ensure that the concentration of the drinking water obtained when the user stops taking water at any time substantially reaches the predetermined mixed concentration.
The mixed concentration refers to the concentration of minerals in the drinking water after mixing the mineral concentrate and the purified water. The mixed concentration may be the mass concentration or the molar concentration of the mineral. Typically, the Total Dissolved Solids (TDS) is used in the water purification industry to characterize the mineral concentration in water, and thus, in this application, the mixed concentration may also be the total dissolved solids per volume of mixed drinking water.
Mineral substance conveying pipeline 11 and water purification pipeline 26 direct connection to water intaking device, and mineral substance concentrate mixes the back with the water purification is direct in water intaking device department and supplies the user to drink during system water every time, because water intaking device can set up the water intaking switch, the low reaches of water intaking switch can not leave the mixed water, takes away when the water intaking is whole. When the next water is taken, the controller can control the first electromagnetic valve on the mineral substance conveying pipeline 11 to be opened in a pulse mode according to the preset mixed concentration set by the user, so that required amount of mineral substance concentrated liquid and purified water can be mixed into drinking water at the water taking device, the concentration of the drinking water is very accurate, and the drinking water cannot be influenced by the preset mixed concentration set when the water is taken last time. In addition, the mineral concentration of the drinking water is adjusted by controlling the first electromagnetic valve 13 to be opened in a pulse mode, an additional micro-channel unit is not needed to be added, and therefore the problem of blocking the micro-channel unit cannot occur in long-term use.
Illustratively, the infusion pump 12 may be a power adjustable infusion pump 12. Thus, the liquid pump 12 can not only pump the mineral concentrate but also adjust the pumping flow rate of the mineral concentrate. In this way, the flow rate of the mineral concentrate delivered by the mineral delivery line 11 can be adjusted by adjusting the power of the liquid pump 12, thereby increasing the freedom of adjustment for the user.
Illustratively, the water intake device may include a faucet 30, and the first solenoid valve 13 may be integrated with the faucet 30. Thereby, the number of parts of the product can be reduced.
For example, a second solenoid valve 21 may be further disposed on the clean water line 26, and the second solenoid valve 21 is used to control the opening and closing of the clean water line 26. The second solenoid valve 21 may be opened when the user takes water and closed when the user stops taking water. The second solenoid valve 21 may also be integrated with the faucet 30.
In one embodiment, the faucet 30 may include a first water inlet channel to which the mineral delivery line 11 communicates and a second water inlet channel to which the clean water line 26 communicates. The first solenoid valve 13 is provided on the first water inflow passage. In the case of including the second solenoid valve 21, the second solenoid valve 21 may be provided on the second water inflow passage. That is, the faucet 30 at this time is actually an electrically controlled faucet. When a user triggers the electric control faucet, the first electromagnetic valve 13 and the second electromagnetic valve 21 start to work, the first electromagnetic valve 13 is opened in a pulse mode, and the second electromagnetic valve 21 is continuously opened. The mineral concentrate and the purified water are respectively discharged from the tap 30 through the first water inlet flow passage and the second water inlet flow passage, and are fully mixed in a water receiving container (such as a water cup) of a user, so that no residual mixed water exists in the tap 30. When drinking water is prepared next time, purified water flows through the second water inlet pipeline from the purified water pipeline 26 and then directly flows into the water cup, mineral concentrated solution flows through the first water inlet channel from the mineral conveying pipeline and then directly flows into the water cup, and the water preparation process is basically not influenced by water preparation last time.
Further, a water inlet solenoid valve 25 may be provided on the clean water pipe 26. A water inlet solenoid valve 25 is provided upstream of the filter element 20. The water inlet solenoid valve 25 can cut off the water flow immediately after the user stops taking water, preventing the water flow from continuously entering the drinking water supply apparatus. This is particularly useful for embodiments where the filter cartridge 20 comprises a reverse osmosis filter cartridge.
The filter element 20 comprises a reverse osmosis filter element, and the water purification effect can be effectively improved. In this case, a booster pump 24 is also provided on the clean water line 26. A booster pump 24 is provided upstream of the reverse osmosis cartridge 20. The water outlet of the water inlet solenoid valve 25 may be connected to the water inlet of the booster pump 24. The water inlet solenoid valve 25 may be connected to a controller. Likewise, when a user fetches water, the controller may open the water intake solenoid valve 25 in response to an electrical signal that the water fetching device is triggered. Water flow may enter the booster pump 24 via a water inlet solenoid valve 25. When the user finishes taking water, the controller may close the water intake solenoid valve 25 in response to an electrical signal that the water intake device is turned off. Therefore, the water flow can be cut off, and the water flow is prevented from continuously entering the water purification system, so that the condition of long-flow wastewater is avoided.
Although only one filter cartridge 20 is shown, one skilled in the art will appreciate that the filter cartridge 20 may include a plurality of filter cartridges for performing multiple stages of filtration. In addition, one or more of the filter elements included in filter element 20 may also be composite filter elements.
