Background

With the pursuit of the public for quality of life, the water quality is getting more attention. Reverse osmosis water purifiers are becoming more popular because the purified water produced by them is fresher, more sanitary and safer.

The raw water has higher TDS (total dissolved solids) more, and the reverse osmosis filter core can block a large amount of ions in the raw water before the osmotic membrane under the effect of booster pump, and makes the TDS of the water through the osmotic membrane accord with the standard of straight drinking water. Meanwhile, the reverse osmosis filter element can discharge high-TDS concentrated water according to a certain proportion when the direct drinking water is prepared.

In the process of water production, although concentrated water can be discharged through a concentrated water pipeline, a small amount of concentrated water still remains in the reverse osmosis filter element before the reverse osmosis membrane after the water production is finished. After long-time shutdown, according to the principle that ions are diffused from high-concentration solution to low-concentration solution, the ions in the concentrated water in front of the membrane can be diffused into the directly drinking water purified behind the membrane, so that the purified directly drinking water is polluted. When the water is taken next time, the polluted direct drinking water can be mixed with new direct drinking water and flow out together, so that the TDS of the first section of water is higher than the standard value.

In order to solve this problem, the prior art usually starts the booster pump periodically to flush the reverse osmosis filter, but although the reverse osmosis filter is flushed, the flushing water is still the raw water with high TDS, so that the reverse osmosis water purifier must be flushed periodically during a long standby period to ensure that the user can obtain water with TDS meeting the standards each time he or she takes water.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

As shown in fig. 1-2, the present invention provides a water purifier 100, which comprises a water inlet solenoid valve 110, a booster pump 120 and a reverse osmosis filter element 130. The water outlet of the water inlet solenoid valve 110 is communicated to the water inlet of the booster pump 120, and the water outlet of the booster pump 120 is communicated to the water inlet of the reverse osmosis filter element 130. The water purifier 100 further comprises a flushing pipeline 140, wherein a water inlet of the flushing pipeline 140 is communicated to the pure water outlet 131 of the reverse osmosis filter element 130, and a water outlet of the flushing pipeline 140 is communicated to a water inlet of the booster pump 120. Namely, the flushing line 140 is a line for allowing the water to flow back from the pure water outlet 131 of the reverse osmosis filter element 130 to the booster pump 120.

The dashed box shown in the figure is a flushing pipeline 140, and the flushing pipeline 140 includes a check valve 200, a water storage device 300 and a flushing solenoid valve 400 which are sequentially arranged along the water flow direction. The check valve 200 can prevent the water in the flushing pipeline 140 from flowing backwards, the water storage device 300 is used for storing pure water prepared by the reverse osmosis filter element 130, and the flushing electromagnetic valve 400 is opened and closed to enable or disable the flushing pipeline 140.

In the normal water intake stage of the user, the flushing solenoid valve 400 is closed, the flushing pipeline 140 is closed, the water inlet solenoid valve 110 is opened, and the booster pump 120 is started. In one embodiment, the raw water passes through the water inlet solenoid valve 110, the booster pump 120 and the reverse osmosis filter 130, and finally pure water is received by the user, and at the same time, a part of the pure water can also flow into the water storage device 300 to be prepared in advance. In another embodiment, the pure water may be preferentially taken by the user, and after the user stops taking the water, the booster pump 120 continues to operate to store the prepared pure water in the water storage device 300.

And in the flushing stage, the water inlet solenoid valve 110 is closed, and the flushing solenoid valve 400 is opened, so that the booster pump 120, the reverse osmosis filter element 130, the water storage device 300 and the flushing solenoid valve 400 form an internal circulation pipeline. After the booster pump 120 is started, a negative pressure is generated at the water inlet of the booster pump 120, and the water storage device 300 is communicated with the water inlet of the booster pump 120 through the flushing pipeline 140, so that pure water in the water storage device 300 is sucked from the water inlet by the booster pump 120 and is discharged from the water outlet, enters the reverse osmosis filter element 130, and flushes the reverse osmosis filter element.

Utilize the pure water to wash reverse osmosis filter core 130 and pipeline, can effectively avoid the raw water in the former pipeline through the osmosis, see through reverse osmosis filter core 130, pollute the pure water behind its membrane, lead to the TDS to rise. Therefore, the TDS of the received first cup of water is higher when the user gets water next time. Moreover, because the water purifier adopts the pure water stored in the water storage device 300 to flush the reverse osmosis filter element 130, the TDS of the pure water after the membrane in the reverse osmosis filter element 130 can be prevented from rising only by flushing once, and the standby time of the water purifier does not need to be considered.

Illustratively, the water purifier 100 further comprises a controller electrically connected to the water inlet solenoid valve 110, the booster pump 120, and the flushing solenoid valve 400, respectively. The controller controls the water inlet solenoid valve 110 to be powered off and closed, controls the flushing solenoid valve 400 to be powered on to conduct the flushing pipeline 140, and controls the booster pump 120 to work within a preset time period after receiving the electric signal for turning off the water taking.

The water taking device can comprise a water taking faucet, a pipeline machine and the like. Wherein the water tap may comprise a mechanical tap; alternatively, the water tap may also comprise an electrically controlled tap. If the water intake device comprises a mechanical tap, in one embodiment, the water intake device may further comprise a high-voltage switch, and the electrical signal for closing the intake of water may be sent by the high-voltage switch, and typically will be sent when the high-voltage switch detects that the pressure in the pipeline in which it is located reaches a set pressure. In another embodiment, a hall inductive switch may be disposed at the switch of the mechanical faucet, and the switch action of the mechanical faucet is converted into an electrical signal through the hall inductive switch.

The electric control faucet and the pipeline machine can be connected and disconnected with the water channel through the electric control valve, the electric control valve can be controlled through the electric control switch, and when the electric control valve is operated by the electric control switch, the electric control faucet and the pipeline machine can send electric signals for opening and closing water taking to the controller, so that the controller can perform subsequent action control on the water purifier.

The above principles of water intake devices and the electrical signals delivered by the water intake devices to shut down are well known to those skilled in the art and will not be described in detail.

The utility model discloses in, in user's water intaking stage, the solenoid valve 110 that intakes gets electricity, is in the open mode, and the raw water is carried for the user after filtering through reverse osmosis filter core 130. After the user stops taking water, the raw water still remains in front of the membrane of the reverse osmosis filter element 130. In order to discharge the raw water, the ion permeable membrane in the raw water is avoided, and then, for example, the flushing operation may be performed immediately after the user stops taking the water. The reverse osmosis filter element 130 is washed by pure water stored in the water storage device 300.

However, due to the slow speed of the ions before penetrating into the membrane, if a user takes water frequently, the TDS of the pure water behind the membrane will not be increased significantly, that is, the TDS of the first cup of water prepared by the system still meets the requirement. Therefore, in order to avoid frequent flushing, save water and reduce the influence on the user experience, a certain time interval (for example, 3 hours, 4 hours or 5 hours) can be set, flushing is performed after the time interval after the user stops fetching water, and if the user fetches water again before the time interval is reached, the controller will count again. That is, if the time difference between two consecutive water fetches by the user is less than the time interval, the reverse osmosis cartridge 130 is not flushed.

Each flush may be completed within a predetermined time period, i.e. the time taken for a single flush is the predetermined time period. In the preset time period, the controller controls the water inlet solenoid valve 110 to be powered off and the flushing solenoid valve 400 to be powered on to conduct the flushing pipeline 140 and control the booster pump 120 to work. The length of the predetermined time period can be calculated according to the water flow rate of the reverse osmosis filter element 130 during flushing, the amount of raw water stored in the reverse osmosis filter element 130, the volume of the water storage device 300 and the like, so that the booster pump 120 is prevented from idling after the water in the water storage device 300 is pumped by the booster pump 120.

It can be seen that the water purifier 100 having the above arrangement can automatically start the flushing stage by controlling the water inlet solenoid valve 110, the booster pump 120, and the flushing solenoid valve 400 by the controller.

Illustratively, the water purifier 100 further comprises a concentrated water solenoid valve 150, wherein a water inlet of the concentrated water solenoid valve 150 is communicated to the concentrated water outlet 132 of the reverse osmosis filter element 130, and the controller opens the concentrated water solenoid valve 150 within the predetermined time period.

At the stage of flushing the reverse osmosis filter element 130 by using the water storage device 300, the controller may open the concentrated water solenoid valve 150, so that the water for flushing the reverse osmosis filter element 130 is discharged from the water purifier 100 through the concentrated water solenoid valve 150, thereby avoiding secondary pollution of the flushing water to the water purifier 100.

According to an aspect of the present invention, there is provided a water purification system, comprising the water purifier as described above. The water purification system further comprises a water intake device 160, as shown in fig. 2, the water outlet of the check valve 200 is communicated with the water intake device 160. The water inlet of the water storage device 300 is communicated between the check valve 200 and the water intake device 160, the water outlet of the water storage device 300 is communicated with the water inlet of the flushing electromagnetic valve 400, and the water outlet of the flushing electromagnetic valve 400 is communicated with the water inlet of the booster pump 120. The flush solenoid valve 400 may be a solenoid valve with one in and one out. The water getting phase and the rinsing phase are the same as those described above and are not described again.

Therefore, with the water purification system arranged above, the flushing solenoid valve 400 can use a solenoid valve with one inlet and one outlet, the solenoid valve has simple action mode and is easy to realize, and the production cost of products can be reduced.

For example, as shown in fig. 1, in the water inlet machine 100, the flushing solenoid valve 400 may be a one-in two-out solenoid valve, and the one-in two-out solenoid valve includes a first water outlet 411 and a second water outlet 412. As is well known to those skilled in the art, the inlet of one of the two inlet and outlet solenoid valves will be communicated with either the first outlet 411 or the second outlet 412. Wherein the first water outlet 411 can be connected to the water inlet of the flushing solenoid valve 400, and the second water outlet 412 can be connected to the water intake device 160.

During the normal water intake phase of the user, the water inlet of the flushing solenoid valve 400 will be communicated with the second water outlet 412. The water intake device 160 in communication with the second water outlet 412 may be an electrically controlled faucet. After the user opens the electric control faucet, the water inlet electromagnetic valve 110 is opened, the booster pump 120 is started, the raw water is filtered by the reverse osmosis filter element 130 to generate pure water, the pure water enters the flushing electromagnetic valve 400 and is discharged from the second water outlet 412, and finally the pure water is taken by the user.

In the flushing stage, the water inlet of the flushing solenoid valve 400 is communicated with the first water outlet 411, and the first water outlet 411 is communicated with the water inlet of the booster pump 120. The water inlet solenoid valve 110 is closed, the booster pump 120 is started, and the booster pump 120 pumps out the pure water in the water storage device 300 on the flushing line 140 by using the negative pressure of the water inlet and presses the pure water into the reverse osmosis filter element 130 to flush the pure water.

Therefore, the flushing solenoid valve 400 of the water purifier 100 adopts a one-inlet two-outlet solenoid valve, and two water outlets of the solenoid valve can be respectively communicated to the water inlet of the booster pump 120 and the water intake device 160, so that the water path can be simplified, the product structure is simpler, the realization is easy, the change of the existing product pipeline can be reduced, and the generation cost is reduced.

For example, the one-in two-out solenoid valve is a solenoid valve whose water inlet is connected to the first water outlet 411 when power is on and whose water inlet is connected to the second water outlet 412 when power is off. Since the flushing stage only occupies a small portion of the total operating time of the water purifier 100, only when the water purifier is flushed, the one-in two-out solenoid valve is powered on to conduct the flushing pipeline 140.

Therefore, the phenomenon of heating of the flushing electromagnetic valve 400 caused by long-time power-on can be avoided, the power consumption of the system is reduced, and the service life of the flushing electromagnetic valve can be prolonged.

For example, in the embodiment where the water purifier 100 includes a controller, the controller may control the water inlet solenoid valve 110 to be de-energized and closed, the one-inlet and two-outlet solenoid valve to be energized to conduct the flushing line 140, and the booster pump 120 to operate during a predetermined period of time when the user stops taking water.

Therefore, the water purifier 100 with the above arrangement can automatically start the flushing stage by controlling the water inlet solenoid valve 110, the booster pump 120 and the one-inlet two-outlet solenoid valve through the controller.

For example, to avoid the user from taking water, the prepared pure water is first stored in the water storage device 300, and the water storage device 300 may be a pressure tank. The pressure in the pressure tank is lower than the outlet water pressure of the booster pump 120, but higher than atmospheric pressure.

Thus, when a user takes water, the water taking device 160 is connected to the atmosphere, and a part of the water taken by the user is directly taken out by the reverse osmosis filter element 130, and a part of the water is squeezed out by the pressure barrel. After the user stops taking water, the water taking device closes the water outlet of the water purifier 100, and when the booster pump 120 is operated, the pressure in the pressure barrel is offset, and water is stored in the pressure barrel until the pressure barrel is full.

Therefore, the water storage device 300 is a pressure barrel, so that the user can take prepared pure water in the water taking stage and preferentially take the pure water under the condition that the water in the water storage device 300 is not full, and the use experience of the user is improved.

Illustratively, the water purifier 100 further comprises a pre-filter 170, and a water outlet of the pre-filter 170 is communicated to a water inlet of the water inlet solenoid valve 110. The pre-filter 170 can be the first coarse filter of the water purifier, can remove the large solid impurities in the raw water, mainly rust, silt, algae, colloid and the like, and can prolong the service life of the reverse osmosis filter 130.

According to an aspect of the present invention, there is provided another water purification system, including the water purifier 100 as described above. The water purifying system further comprises a water intake device 160, and the water intake device 160 is communicated with the second water outlet 412 of the water purifying machine.

For example, in all water purification systems as described above, the water intake device 160 may comprise an electrically controlled faucet. The water purifier 100 is controlled by the electric control faucet, so that the number of parts in the water purifier 100 can be reduced, and the water path of the water purifier 100 can be simply set.
