Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a water purifier with a raw water pretreatment function. Background Art

[0002] With the development of society, water purifiers have gradually entered thousands of households, and reverse osmosis (RO) water purifiers are currently a commonly used type of water purifier. The outlet TDS (Total Dissolved Solids) is the main indicator for measuring the filtering effect of reverse osmosis (RO) water purifiers. When the RO machine is working normally and continuously, the TDS removal rate can reach more than 90%. However, since the quality of water input into the water purifier is often different, the water purifier has certain limitations. For example, urban areas use tap water, which has uniform water quality and is usually not mixed with impurities insoluble in water. Therefore, urban areas can directly connect tap water to the water purifier when using it. Rural areas, factory areas, and campuses use well water and other groundwater, which contains more impurities insoluble in water (mud, leaves, etc.). When facing well water and other groundwater, the water purifiers currently on the market are often blocked by impurities insoluble in water (mud, leaves, etc.) RO membranes, affecting the water purification effect. At the same time, after completing the water purification work for well water and other groundwater, it takes longer, more pure water, and more energy to clean the water purifier. At the same time, during the water purification process, there is a risk of damage to the water purifier by impurities insoluble in water (scratching the RO membrane and other components), thereby greatly reducing the life of the water purifier.

[0003] At the same time, the reverse osmosis structure of the water purifier, for example, the reverse osmosis (RO) membrane, will contaminate the pure water produced previously due to the osmotic effect after the water purifier stops working, resulting in a high TDS value of the first cup of water produced when the water purifier works again, which does not meet user needs.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] The embodiment of the present application provides a water purifier with a raw water pretreatment function, comprising: a pre-water storage container 1 and a water purification system 2, the pre-water storage container 1 comprising a water inlet 11, a raw water treatment system 12, a first water outlet 13 and a second water outlet 14, the water inlet 11 is connected to the water inlet end of the raw water treatment system 12, the first water outlet end of the raw water treatment system 12 is connected to the first water outlet 13, the first water outlet 13 is connected to the first water inlet end 22 of the water purification system 2, the second water outlet end of the raw water treatment system 12 is connected to the second water outlet 14, the raw water treatment system 12 is arranged in the pre-water storage container 1, and the water inlet 11, the first water outlet 13 and the second water outlet 14 are all arranged on the side wall of the pre-water storage container 1.

[0029] By adding a pre-water storage container in front of the water purifier, the water input into the water purifier is pre-treated raw water, for example, raw water after sedimentation, raw water after filtration, etc., so that the number of times the raw water is filtered and processed in the water purifier is reduced, thereby reducing the working pressure of the water purifier, and preventing water-insoluble impurities, large particles of impurities, etc. from entering the water purifier and causing damage to the water purifier, and preventing water-insoluble impurities, large particles of impurities, etc. from accumulating in the water purifier and causing inconvenience to the cleaning process of the water purifier.

[0030] Another connection method between the pre-water storage container 1 and the water purification system 2 is: the pre-water storage container 1 is connected to the pure water outlet end of the water purification system 2. When the pre-water storage container is connected to the water outlet end of the water purification system in the water purifier, the pre-water storage container receives the pure water discharged from the water outlet end of the water purification system, and the water in the pre-water storage container is a mixture of pure water and raw water. The TDS value of the mixed water is obviously lower than the TDS value of the raw water. When the mixed water is used to clean the water purification system in the water purifier, the water purification system is in water with a lower TDS. When the cleaned water purifier is used again, the TDS value of the first cup of water produced is lower. At the same time, a pre-water storage container is added, and the raw water can be pre-treated in the pre-water storage container.

[0031] Specifically, the water outlet of the water purification system in the water purifier can also be connected upstream of the water inlet of the pre-water storage container 1, that is, the water input into the pre-water storage container 1 is a mixture of pure water and raw water, and then the pre-water storage container 1 inputs the mixed water into the water purification system 2. When the water purification system 2 uses the mixed water for cleaning, the TDS value of the mixed water is obviously lower than the TDS value of the raw water, so that the water purification system is in water with a lower TDS, and then when the cleaned water purifier is used again, the TDS value of the first cup of water generated is lower; due to the different cleaning rules of the water purification system 2, it may not be necessary to clean the water purification system 2 every time the water purification system 2 stops generating pure water, that is, when the water purification system 2 uses the mixed water not for cleaning but for generating pure water, because the TDS value of the mixed water is obviously lower than the TDS value of the raw water, compared with the process of generating pure water using raw water as raw material, the process of generating pure water using mixed water as raw material puts less pressure on the water purification system 2.

[0032] Embodiment 1:

[0033] like Figure 1As shown, when the water purifier described in the present application starts to work, the front water storage container 1 is a front water storage tank (rectangular structure), the water inlet 11 of the front water storage container 1 receives raw water from an external water source, and transmits the raw water to the raw water treatment system 12, the raw water treatment system 12 performs sedimentation, filtration and other treatments on the raw water, and transmits the treated raw water to the first water outlet 13 of the front water storage container 1 through the first water outlet end of the raw water treatment system 12, the first water outlet 13 transmits the treated raw water to the first water inlet end 22 of the water purification system 2, that is, the water purification system 2 performs a water purification process on the treated raw water. At the same time, the raw water containing impurities cannot be used for daily life such as cleaning and washing, but the use of the water purification system It is very wasteful to use the pure water output by the system for daily life such as cleaning and washing (wasting drinking water and wasting electricity costs). Therefore, the treated raw water is connected to the second water outlet 14 of the pre-water storage container 1 through the second water outlet end of the raw water treatment system 12, and the second water outlet 14 is connected to the valve (faucet) used in daily life, that is, the raw water that has completed sedimentation, filtration and other treatments is directly used for daily life such as cleaning and washing, which meets the needs of daily life such as cleaning and washing and avoids waste; if the water treated by the pre-water storage container 1 can meet the preset requirements, the first water outlet 13 of the pre-water storage container 1 is directly connected to the water outlet end of the water purification system through the pure water reflux valve group 3, so as to avoid inputting water that meets the preset requirements into the water purification system.

[0034] Embodiment 2:

[0035] When the water purifier described in the present application starts to work, when the external water source is uneven in quality, that is, underground water such as well water containing impurities (mud, leaves, etc.), the front water storage container 1 is a front water storage tank (rectangular structure), and the water inlet 11 of the front water storage container 1 receives raw water from the external water source and transports the raw water to the raw water treatment system 12. The raw water treatment system 12 performs sedimentation, filtration and other treatments on the raw water, and transports the treated raw water to the first water outlet 13 of the front water storage container 1 through the first water outlet end of the raw water treatment system 12. The first water outlet 13 The treated raw water is transmitted to the first water inlet end 22 of the water purification system 2, that is, the water purification system 2 performs a water purification process on the treated raw water. At the same time, the raw water containing impurities cannot be used for daily life such as cleaning and washing, but using the pure water output by the water purification system for daily life such as cleaning and washing is very wasteful (wasting drinkable water and wasting electricity costs). Therefore, the treated raw water is connected to the second water outlet 14 of the front water storage container 1 through the second water outlet end of the raw water treatment system 12, and the second water outlet 14 is connected to the valve (faucet) used in daily life.

[0036] like Figure 2As shown, when the water purifier described in the present application starts to work, when the external water source provides raw water with uniform water quality, for example, tap water, since the tap water has completed a series of treatments such as sedimentation, filtration, and disinfection in the water plant before being transported, there is no need to repeat the sedimentation and other treatments on the raw water, and when the water purification system is not required to treat the raw water, the second water outlet 14 of the front water storage container 1 is directly connected to the water outlet end of the water purification system through the pure water reflux valve group 3. At this time, the water purification system 2 closes the water inlet process of the first water inlet end 22. The pure water reflux valve group 3 includes at least one of a one-way valve, a pressure relief valve and a solenoid valve; as shown in FIG. Figure 2 As shown, the water outlet of the pre-water storage container is connected to the water outlet of the water purification system in the water purifier. When the pre-water storage container is cleaned, the first water outlet 13 will not deliver the treated raw water to the water purification system. Therefore, there is no input water flow from the first water outlet 13 and the cleaning water outlet 21. The first water outlet 13 and the pipeline between the cleaning water outlet 21 and the water purification system are flow-free pipelines. Then, the first water outlet 13 is connected to the water outlet of the water purification system 2 through the pure water reflux valve group 3, so that the pure water output by the water purification system 2 can be transferred to the pre-water storage container 1 to clean the pre-water storage container 1. Figure 2 As shown, the water outlet end of the pre-water storage container is connected to the water outlet end of the water purification system in the water purifier. When the water purification system 2 is cleaned, the raw water (pre-treated raw water) output by the pre-water storage container is merged with the pure water produced by the water purification system, and the merged water is input into the water purification system 2 to clean the water purification system 2, so that the water purification system is in water with lower TDS. When the cleaned water purifier is used again, the TDS value of the first cup of water produced is lower.

[0037] Specifically, by setting a one-way valve, the water flow direction can only be from the cleaning water outlet 21 to the first water outlet 13, ensuring that the pure water output by the water purification system 2 is transmitted to the front water storage container 1 without backflow; specifically, by setting a combination of a solenoid valve and a one-way valve, the process of transmitting the pure water output by the water purification system 2 to the front water storage container 1 is controllable, that is, after the solenoid valve receives the electromagnetic command to open, the pure water output by the water purification system 2 will be transmitted to the front water storage container 1 through the solenoid valve and the one-way valve.

[0038] like Figure 3As shown, when the water purifier described in the present application is shut down (water purification is stopped), in order to ensure that the first cup of water of the water purifier when it works next time meets the actual demand, for example, a hot water device with a water purifier, in order to ensure that the first cup of water when the hot water device works again after stopping working is hot water, it is necessary to recycle the water that has not been discharged in the pipeline of the hot water device with a water purifier, and the recycled water can be used to clean the water purifier, that is, the water purifier is cleaned by using the recycled water through the internal pipeline of the hot water device with a water purifier. For the recycled water, the recycled water can also be used to clean the pre-water storage container 1, that is, the water purifier discharges the recycled water from the water outlet end of the water purifier, and the recycled water is transported to the water inlet 11 of the pre-water storage container 1 through the pure water reflux valve group 3, so that the recycled water is injected into the pre-water storage container 1, that is, the recycled water flows from the cleaning water outlet 21 to the water inlet 11, and the raw water and the recycled water are mixed and then injected into the pre-water storage container 1 to clean the pre-water storage container 1. For example, if the TDS of raw water is 1 and the TDS of recycled water (pure water) is 0.1, then after the raw water and recycled water are mixed, the TDS of the mixed water must be less than 1. Therefore, the mixed water is used to clean the pre-water storage container 1 to ensure the cleaning effect.

[0039] When cleaning the water purification system 2, the pure water generated by the water purification system is merged with the raw water to be input into the pre-water storage container 1, that is, the recycled water flows from the cleaning water outlet 21 to the water inlet 11, the raw water and the recycled water are mixed and then injected into the pre-water storage container 1, and the merged water is input into the water purification system 2 through the pre-water storage container 1 to clean the water purification system 2, so that the water purification system is in water with lower TDS, and then when the cleaned water purifier is used again, the TDS value of the first cup of water generated is lower.

[0040] like Figure 4 As shown, when the water purifier described in the present application starts to work, when the external water source provides raw water with uniform water quality, for example, tap water, since the tap water has completed a series of treatments such as sedimentation, filtration, and disinfection in the water plant before being transported, there is no need to repeat the sedimentation and other treatments on the raw water, but the water purification system is still required to perform other treatments on the raw water (such as disinfection, etc.), so the raw water needs to be input into the water purification system, that is, specifically, the water purification system 2 also includes a second water inlet end 23, and the first water outlet 13 is connected to the second water inlet end 23. For example, the water purification system needs to treat the raw water twice, the first treatment uses an integrated filter element, and the second treatment is reverse osmosis treatment. The second water inlet end 23 transports the raw water to the position after the first treatment and before the second treatment. At this time, the water purification system 2 closes the water inlet process of the first water inlet end 22.

[0041] In a possible implementation, the raw water treatment system includes a water inlet pipe 121, a slow flow baffle 122, a first filter device 123, and a second filter device 124;

[0042] Among them, the slow-flow baffle 122 is arranged in the front water storage container at a preset angle, the front water storage container is a front water storage tank, the preset angle is the angle (130°) between the slow-flow baffle and the extension line of the water inlet, the first filter device 123 is arranged in the front water storage container parallel to the plane where the first water outlet is located, and the second filter device 124 surrounds the second water outlet.

[0043] In a possible implementation, the water inlet pipe 121 passes through the side wall of the front water storage container, and one end of the slow flow baffle 122 is fixed to the inner wall of the top surface of the front water storage container.

[0044] In a possible implementation, Figure 4 As shown, the first filter device 123 includes a filter frame 1231 and a first filter 1232 . The filter frame 1231 is embedded in a groove on the inner wall of the front water storage container, and the first filter 1232 is fixedly laid on the filter frame 1231 .

[0045] In a possible implementation manner, the first water outlet 13 is disposed on a side wall of the front water storage container, and the side wall where the first water outlet is located is opposite to the side wall where the water inlet 11 is located.

[0046] In a possible implementation, the raw water treatment system 12 further includes a water quality detector 125 , and the water quality detector 125 is disposed at the first water outlet 13 .

[0047] Embodiment three:

[0048] like Figure 5-Figure 6As shown, the slow-flow baffle 122 is arranged in the front water storage container at a preset angle, and the front water storage container is a front water storage tank. The preset angle is the angle (130°) between the slow-flow baffle and the extension line of the water inlet. The first filter device 123 is arranged in the front water storage container parallel to the plane where the first water outlet is located, and the second filter device 124 surrounds the second water outlet. Among them, two slow-flow baffles 122 can be set, that is, fixed on the top surface of the water tank and fixed on the side wall of the water tank, so as to better slow down the flow and avoid the water flow velocity input by the water inlet pipe 121 being too large, which affects the sedimentation effect. The first filter device 123 includes a filter screen frame 1231 and a first filter screen 1232, the filter screen frame 1231 is embedded in the groove on the inner wall of the front water storage container, that is, the first filter device 123 is perpendicular to the front and rear side walls of the water tank, the first filter screen 1232 is fixedly laid on the filter screen frame 1231, the first water outlet 13 is arranged on the side wall of the front water storage container, the side wall where the first water outlet 13 is located is opposite to the side wall where the water inlet 11 is located, ensuring that the water input from the water inlet 11 flows out from the first water outlet 13 after slow flow, sedimentation and filtration, the second filter device 124 can be a hemisphere composed of a filter screen, surrounding the second water outlet, that is, the hemisphere buckles the second water outlet 14, and the water quality detector 125 is arranged at the first water outlet 13, that is, the water quality is detected at the first water outlet 13, so that the user can judge whether the current water can be sent to the water purification system 2.

[0049] In a possible embodiment, the raw water treatment system further includes a sewage outlet 126, a cleaning outlet 127 and a cleaning device 128, the sewage outlet 126 is arranged on the bottom surface of the pre-water storage container, the cleaning outlet 127 is arranged on the side wall where the first water outlet is located, and the cleaning device 128 includes a cleaning pipe 1281 and a cleaning nozzle 1282, one end of the cleaning pipe 1281 passes through the cleaning outlet 127 and extends into the pre-water storage container 1, the cleaning nozzle 1282 is connected to the cleaning pipe 1281, and the cleaning nozzle 1282 is arranged in the pre-water storage container.

[0050] Embodiment five:

[0051] like Figure 5As shown, the sewage outlet 126 is arranged on the bottom surface of the front water storage container, so that the accumulated impurities are easier to discharge, and the cleaning port 127 is arranged on the side wall where the first water outlet is located, that is, to ensure that the first filter device will be cleaned during the cleaning process, and the cleaning device 128 includes a cleaning pipe 1281 and a cleaning nozzle 1282, one end of the cleaning pipe 1281 passes through the cleaning port 127 and extends into the front water storage container 1, and the cleaning nozzle 1282 is connected to the cleaning pipe 1281, and the cleaning nozzle 1282 is arranged in the front water storage container. Specifically, the cleaning nozzle 1282 is a shower head structure, which can spray multiple streams of water at the same time. Compared with directly spraying water from a water pipe, the cleaning process is more time-saving and labor-saving.

[0052] In a possible implementation, the water purification system has a normal water and water power backwashing scheme 1: after a certain volume / time, the water is turned off and the low flow is turned on, the pure water backflow is turned on, the pure water is returned to the front core and mixed with tap water in a certain proportion, and enters the membrane filter element to flush the membrane for a period of time. At this time, the membrane is flushed and soaked with water with lower TDS, and the concentration of the first cup of water will be relatively low next time. And because the water concentration of the membrane is low, the water concentration in the back is even lower, and the next water intake will have better TDS buffering capacity. Then the wastewater network group opens the high flow rate mode, the pure water return water circuit is closed, and the tap water pushes out the mixed water in the front to replace the raw water and water in the membrane filter element, so that the membrane is in a water quality loop with a lower TDS, to further reduce the TDS of the next head water; after a certain amount of water production / time, the water intake is stopped and the reflux flushing is started (the pure water remaining in the pipeline is used for cleaning), the faucet valve is closed, the wastewater valve is opened at a low flow, and the pure water reflux is opened, and the pure water is returned to the front (front water storage container 1) and combined with the tap water for a certain period of time, and enters the membrane core to flush the membrane for a period of time. At this time, the membrane is flushed and soaked with water with a lower TDS, and the concentration of the next head water will be relatively low. And because the concentration of the membrane's inlet water is low, the water concentration in the rear is even lower, and the next water intake will have better TDS flushing ability. Then the wastewater valve group opens the high flow rate mode, the pure water return water circuit is closed, and the tap water pushes out the mixed water in the front volume to replace the raw water and concentrated water in the membrane filter element, so that the membrane is in a water quality environment with lower TDS, so as to further reduce the TDS of the next water intake head water; a detector for detecting TDS is set in the water circuit and the combined water inlet circuit / water inlet circuit to detect the TDS value and the flushing effect is analyzed by the system, and the flushing time and the conversion of the flushing stage are controlled according to the relative TDS of the water circuit. (This method requires obtaining model data in advance according to different water circuit structures, and then establishing a TDS relative value database for different water quality conditions based on the model data, intelligently controlling the opening and closing of the flushing stage for different water qualities, and deciding when to enter the next stage of flushing.
