Detailed Description

The following discloses many different embodiments or examples for implementing the subject technology described. Specific examples of components and arrangements are described below to simplify the present disclosure, but these are merely examples and do not limit the scope of the invention. For example, if a first feature is formed over or on a second feature described later in the specification, this may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact. Additionally, reference numerals and/or letters may be repeated among the various examples throughout this disclosure. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. Further, when a first element is described as being coupled or coupled to a second element, the description includes embodiments in which the first and second elements are directly coupled or coupled to each other, as well as embodiments in which one or more additional intervening elements are added to indirectly couple or couple the first and second elements to each other.

The large-flow water purification system shown in fig. 1 includes a booster pump 1 for boosting water, a reverse osmosis membrane filter element 2 for filtering the boosted water, and a water storage container 3 for caching the filtered water. The high-flow water purification system shown in fig. 1 is suitable for household water purifiers and also comprises optional components, namely a water inlet tee 51, a pre-filter element 52, a water inlet solenoid valve 54, a water outlet solenoid valve 57, a pump 58 and a water outlet terminal device 4. According to the utility model discloses a large-traffic water purification system is not limited to family expenses, also is fit for other occasions.

The reverse osmosis membrane filter element 2 comprises a water inlet, a waste water port and a pure water port, wherein the water inlet is communicated with the water outlet side of the booster pump 1, the waste water port is communicated with a waste water electromagnetic valve 56, and the pure water port is communicated with the water tank 3. The reverse osmosis membrane filter element 2 filters the water pressurized by the booster pump 1, and the purified water and the wastewater are discharged from a pure water port and a wastewater port respectively. The purified water enters the water storage container 3 through a pipeline. The wastewater is discharged through the wastewater solenoid valve 56 via a pipeline or a part of the wastewater is recovered through a pipeline not shown in the figure, mixed with the raw water and then subjected to the filtration of the reverse osmosis membrane filter element 2 again.

The reverse osmosis membrane cartridge (RO cartridge) has a water production rate selected between 300G (gallons) and 600G, preferably 2G, for the purpose of achieving an instantaneous high flow rate of water and keeping the system volume from increasing significantly. Because the water yield of the reverse osmosis membrane filter element is limited between 300G and 600G, the volume of the water storage container 3 can be miniaturized on one hand, and the water storage container 3 can be supplied with large-flow pure water or domestic water outwards on the other hand, in other words, the water can be supplied to the water outlet terminal device 4 in a mode that the water outlet flow is more than 3L/min. The water storage tank 3 can be filled without producing a large amount of water because the water storage tank 3 is allowed to be miniaturized, and the water production per unit time of the reverse osmosis membrane filter element is between 300G and 600G, so the miniaturized water storage tank 3 can be filled in a short time. This is very important for the user. The user stops getting water after the demand of getting water once is satisfied, even if the water cached in the water storage container 3 is used up or almost used up in the demand of getting water once, for example, water making is started when reaching the water tank early warning line, the water can be filled in a short time after stopping getting water or in a time that the user can not notice, therefore, the water purifying system can meet the requirement of getting water instantly.

Taking the water storage container with the water storage capacity of 2G as an example, the water storage container can be a water tank or a pressure barrel. As shown in the table I, when the reverse osmosis membrane filter element with the water yield of 150G per unit time is selected, the flow of the water outlet terminal device is basically 0.5L/min at the pure water outlet end of the reverse osmosis membrane filter element under the condition that the water storage container is not configured, and the flow of the water outlet terminal device is 2.6L/min under the condition that the water storage container is configured when the system works. Similarly, with the aid of table one, it can be seen that the water supply flow rates were both when the water storage tank was configured and when the water production per unit time was selected to be 300G, 400G, 500G, 600G. By comparing the data in table one, it can be found that when the flow rate is greater than 300G, the flow rate of 3L/min can be achieved by configuring the water tank or the pressure tank, and the flow rate increases as the water yield per unit time (i.e. membrane area) of the reverse osmosis membrane filter element increases, but when the flow rate reaches more than 400 gallons, the flow rate is basically unchanged, and the larger the membrane area is, the higher the cost is, so that the water yield is preferably 300-600G, and the most preferable is 400G.

Serial number	RO filter element water yield	Water outlet flow of non-water storage container	Water outlet flow of water storage container (2G)
				1	150G	0.5L/min	2.6L/min
2	300G	0.9L/min	3L/min
				3	400G	1L/min	4.2L/min
4	500G	1.3L/min	4.5L/min
				5	600G	1.5L/min	4.8L/min

Flow rate table

The general water intake of the user is about 5L, taking the water yield of 400G as an example, the water outlet terminal device can take water at the flow rate not higher than 4.2L/min. Supposing that the water supply is carried out at the maximum flow of 4.2L/min and the water taking amount of a user is 5L, when the user starts the water outlet terminal device, the booster pump 1 works simultaneously to make water through the reverse osmosis membrane filter element 2, and pure water or purified water is discharged outwards while receiving new made water in the water storage container, so that the user can take water in the flow mode of a conventional tap water faucet, the experience of slow water outlet speed is avoided, and the water storage container can be filled again within about 5 minutes after the requirement of one-time water taking is met, and under the normal condition, the time for the user to intervene in other affairs is more than 5 minutes, so that the waiting time is not needed when the next water taking requirement of the user is met.

As can be understood from the table one, on the one hand, the larger the water yield per unit time of the reverse osmosis membrane filter element 2 is, the faster the water outlet speed per minute of the water purification system is, for example, in the second column of table one, the water yield of the reverse osmosis membrane filter element 2 is gradually increased, and the water outlet speed of the water purification system is also gradually increased, and the third column also shows that the water outlet speed of the water purification system is gradually increased. On the other hand, for the reverse osmosis membrane filter element 2 with the same water yield per unit time, the water purification system is provided with the water storage container which is obviously different from the water-free container, and when the water storage barrel is arranged for water preparation in advance, the water outlet speed is much higher than that of direct water preparation, for example, when the capacity of the water storage container is 2G, in a test with the serial number of 1, the water outlet speed is 2.1L/min higher than that of the water-free container; in the test with the serial number of 2, the water outlet speed is 2.1L/min higher than that of a water-free container; in the test with the serial number of 3, the water outlet speed is 3.2L/min higher than that of a water-free container; the water discharge speed was 3.2L/min higher than that of the non-water storage container in the test No. 4, and 3.3L/min higher than that of the water storage container in the test No. 5. Therefore, the water outlet rate of the water purification system can be increased by increasing the gallons of the reverse osmosis membrane filter element 2 and configuring the water storage container. However, as can be seen in the third column of table one, as the gallons of the reverse osmosis membrane cartridge 2 increase, the rate of flow of the outlet water decreases and the 4.8L/min outlet water rate is closer to the conventional faucet outlet water rate, thus eliminating the need to further increase the gallons of the reverse osmosis membrane cartridge 2. In addition, as the gallons of the reverse osmosis membrane cartridge 2 increase, the cost increases dramatically in a non-linear manner, and thus the gallons of the reverse osmosis membrane cartridge 2 are controlled simultaneously when configuring the high flow rate effluent parameter. In the foregoing embodiment, the water storage tank is provided so that the number of gallons of the reverse osmosis membrane cartridge 2 can be controlled within a suitable range. The water reservoir 3 is a miniature water reservoir in the embodiment shown in fig. 1, which is generally a miniature water reservoir with a volume of about 1 gallon to 3 gigabytes, preferably 2 gigabytes, and the water reservoir 3 with an excessive volume takes up a large space in the cabinet and causes excessive water storage and waste. The water tank may be selectively provided with a sterilizer and a water level sensor. The bottom of the water storage container 3 is communicated with the water outlet terminal device 4 through a pipeline. The outlet terminal device 4 is shown as a faucet, but is not limited thereto, and may be a water outlet nozzle controlled by a switch such as a button or a knob. A water outlet solenoid valve 57 and a pump 58 are provided in a pipe between the water outlet terminal device 4 and the water outlet container 3. When the system is not operating, the water outlet solenoid valve 57 closes the line to keep water in the water storage tank 3. The pump 58 is used to maintain a steady flow of effluent and supply water at a high flow rate.

An alternative is to provide a water inlet solenoid valve 54 in the piping on the upstream side of the booster pump 1, and the water inlet solenoid valve 54 is closed when the system is not in operation.

Yet another alternative arrangement is to provide a pre-filter element 52 on the upstream side of the booster pump 1, the pre-filter element 52 being, but not limited to, PP wool and/or activated carbon. The pre-filter element 52 is used for rough filtration to prolong the service life of the booster pump 1 and the reverse osmosis membrane filter element 2 or improve the working performance thereof.

A water purifier can be constructed according to the water purifying system shown in fig. 1 and fig. 2, and the water purifier comprises a housing, and a booster pump 1, a reverse osmosis membrane filter element 2, a water storage container 3 or 6, a front filter element 52, TDS probes 53 and 55, and the like are arranged in the housing optionally. Since the water production per unit time of the reverse osmosis membrane cartridge is limited to 300G to 600G, the water storage tank 3 or 6 can be miniaturized, and thus the space requirement inside the housing can be reduced.

The water purification system is also optionally provided with a controller which receives the water supply signal and starts the booster pump 1 to produce water after receiving the water supply signal. When the water outlet terminal device 4 is an intelligent faucet, a user can output a water supply signal through the water outlet terminal device 4 to turn on the water outlet terminal device 4 and turn on the booster pump 1 by the system at the same time. The method of generating the water supply signal is not limited to this, and for example, a flow sensor may be provided downstream of the water storage device 3 or 6, and the water supply signal may be generated by determining that the outlet end device 4 is turned on based on a change in the flow rate.

In an embodiment, the controller further receives a water level signal of the water storage container, determines whether the user has a normal water intake demand according to the water level signal, sends the water level signal when the water level sensor in the water storage container 3 or 6 detects that the water level reaches a set position, and only after receiving the water level signal and the water supply signal, the booster pump 1 is started to produce water, so that the booster pump 1 is repeatedly started under the condition that the water outlet terminal device 4 is frequently started.

An optional configuration is that TDS probes 55 and 53 are respectively arranged on a pipeline on the purified water outlet side of the reverse osmosis membrane filter element 2 and a pipeline on the upstream side of the booster pump 1, and the TDS probes 55 and 53 are used for detecting corresponding potential values by setting water quality parameters under a certain temperature condition, further calculating the conductivity of corresponding water and converting the TDS values through a certain proportional relation. Different values of the TDS probes 55 and 53 can reflect the working state of the reverse osmosis membrane filter element 2 to a certain extent, and the detection results of the TDS probes 55 and 53 can be displayed for a user to make reference through a display device and can also be used for controlling the working state of the system.

The aforementioned water purification system is not limited to a household water purification system or a household water purifier. The aforementioned controller comprises one or more hardware processors, such as one or more combinations of microcontrollers, microprocessors, Reduced Instruction Set Computers (RISC), Application Specific Integrated Circuits (ASIC), Application Specific Integrated Processors (ASIP), Central Processing Units (CPU), Graphics Processing Units (GPU), Physical Processing Units (PPU), microcontroller units, Digital Signal Processors (DSP), Field Programmable Gate Arrays (FPGA), Advanced RISC Machines (ARM), Programmable Logic Devices (PLD), any circuit or processor capable of executing one or more functions, or the like.

Fig. 2 shows another embodiment of the large flow water purification system, which differs from fig. 1 in that the water storage is replaced by a pressure tank 6 from the water tank, and correspondingly a one-way valve 7 is arranged on the water inlet side of the pressure tank 6, and a high pressure switch 8 is arranged on the water outlet side, and the high pressure switch 8 closes the pipeline and bears the internal pressure of the pressure tank 6 when water is not taken. The embodiment shown in fig. 2 also has the aforementioned advantages.

The embodiments shown in fig. 1 and 2 also have the following modifications:

variation 1: only the wastewater port of the reverse osmosis membrane filter element 2 is communicated with a water storage container;

variation 2: the waste water port and the pure water port of the reverse osmosis membrane filter element are respectively communicated with a water storage container.

In this variant, large flows of domestic and/or pure water can also be obtained without a significant increase in the system volume and without a significant increase in costs.

The term water production per unit time as used in this patent generally refers to water production of 24 hours a day.
