Description

Multifunctional water treatment machine

Technical Field

The invention relates to the technical field of water treatment, in particular to a multifunctional water treatment machine, wherein the multifunctional water treatment machine can carry out purification treatment and softening treatment on water. Further, the multifunctional water treatment machine can also carry out reverse osmosis treatment on water. In particular, the purification device (purification cartridge) and the softening device (softening tank) of the multifunctional water treatment machine of the present invention are both provided in the multifunctional water treatment machine, and are provided so that the purification and softening treatment of raw water (or water to be treated) can be achieved through a single control valve, thereby enabling a user to obtain purified water and softened water at the same time.

Background

With increasing health concerns and concerns about water pollution problems, water treatment machines or water treatment systems have become common household appliances. Water treatment machines, particularly domestic water treatment machines such as central water purifiers, water softeners and the like are often installed in kitchens to treat water and obtain cleaner water.

Water processors are generally classified into water purifiers and water softeners according to the treatment mode of raw water or water to be treated. Common water purifiers, such as activated carbon filtration water purifiers, ultrafiltration water purifiers, RO membrane water purifiers, and the like, are often used for removing impurities, such as harmful substances and foreign substances, from water as much as possible. The water softener is mainly used for removing calcium ion plasma in water. The water obtained by treating the raw water by the water purifiers such as the ultrafiltration water purifier, the RO membrane water purifier and the like is cleaner and is suitable for drinking, and the soft water obtained by treating the raw water by the water softener is more suitable for bathing, clothes washing and the like because the soft water contains less calcium ions and the like. Soft water is also believed to be more cosmetically acceptable. However, most of the existing water processors having a complex water treatment function are water processors which simply purify water, such as an activated carbon-ultrafiltration filtration composite water purification system, an ultrafiltration-RO membrane composite water purification system, a PP cotton-activated carbon composite water purification system, etc., but there are few multifunctional water processors which can achieve purification and softening treatment of water, let alone can achieve purification, softening and reverse osmosis treatment (or RO membrane treatment) of water. The main reason is that there is a great difference in mechanism or mechanism in the purification, softening and reverse osmosis treatment of water. When purifying water, a user needs to replace the filter element periodically so as to prevent the purifying filter element from losing the purifying function after long-time use. For example, although flushing and the like can extend the life of the filter cartridge, the activated carbon filter cartridge and the ultrafiltration filter cartridge need to be replaced after a long period of use. After the water is softened, the water softener needs to periodically supplement salt solution (generally NaCl solution) into the softening tank (or softening tank) and clean the softening tank to avoid the deactivation of the softening resin in the softening tank and the removal of impurities in the softening tank after long-term use. When reverse osmosis treatment is carried out on water, when the RO membrane used for reverse osmosis is poor in water quality, membrane blocking easily occurs and the service life of the RO membrane is shortened. For example, when the hardness of the water to be reverse osmosis-treated is too high, clogging of the RO membrane and a decrease in the reverse osmosis-treating ability thereof are liable to occur. In addition, in practical application, the service life of the softening resin obviously exceeds that of the filter element. Therefore, in addition to replenishing the brine into the softening tank, the water softener needs to replenish water into its brine tank during the softening process of water to prevent the brine in the brine tank from being consumed and the brine from being supplied into the softening tank. However, the implementation of all water treatment functions of the above-described water treatment machine involves the control of the water flow. Due to the complexity of the structure and function implementation of the water softener for softening water, the water treatment machine having the functions of purifying and softening water is required to form a complicated waterway and to be able to realize reasonable control thereof. In order to realize the control of the water purifying passage and the softening water passage at the same time, most of the existing multifunctional water treatment machines are provided with more than two control valves, which finally results in the whole water treatment machine mechanism being bulky, large and poor in use experience. The structure of the multifunctional water treatment machine capable of realizing the purification, softening and reverse osmosis treatment (or RO membrane treatment) of water is more complex. Furthermore, water treatment machines, particularly domestic water treatment machines, are typically mounted under kitchen countertops, such as under a sink. The prior multifunctional water treatment machine has huge volume, occupies excessive space and brings great inconvenience to the installation of users. Not to mention maintenance and cartridge replacement when the water treatment machine fails. In addition, the conventional multifunctional water treatment machine rarely provides purified water to a user at the same time when softening water. Even more, some multi-functional water processors provide only demineralized water, and not purified water. The user has to obtain purified water through an additional water purifier. Finally, for safety reasons, it is necessary for water treatment apparatuses, in particular water treatment machines with complex water treatment functions, to continuously supply water (or raw water) in a non-water treatment operating state. However, most of the existing multifunctional water treatment machines can only provide purified water and/or softened water at the purification or/and softening function site, and cannot continuously provide water in other working states, such as a cleaning working state of a purification filter element of the purification device.

Thus, when the control valve 10 is a planar valve, the spool 1 of the control valve 10 includes the movable valve plate 13 and the fixed valve plate 12. Further, it can be understood that since the valve inner chamber 110 of the valve body 11 of the planar valve 10 communicates with the first opening 1101, water to be treated is provided through the first opening 1101 and the valve inner chamber 110.

As shown in fig. 1A to 17 of the drawings, the softening device 30 of the multifunctional water-treating machine according to the preferred embodiment of the present invention further comprises an ejector 32 and a salt solution tank 33, wherein the ejector 32 has an ejection port 321 adapted to communicate with the third opening 1103 of the valve body 11 and an ejection port 322 adapted to communicate with the fourth opening 1104 of the valve body 11, wherein the salt solution tank 33 is adapted to communicate with the ejector 32 so that salt solution from the salt solution tank 33 can flow through the ejector 32 and the fourth opening 1104 and through the plane valve 10 to the softening tank 31 of the softening device 30, thereby regenerating the softened resin in the softening tank 31.

As shown in fig. 1A to 3G of the drawings, when the multifunctional water treating machine according to the preferred embodiment of the present invention is in the first operating state, the first communication passage 1001 formed by the plane valve 10 is respectively communicated with the first opening 1101 and the fifth opening 1105 of the valve body 11, the second communication passage 1002 is respectively communicated with the second opening 1102 and the seventh opening 1107 of the valve body 11, the third communication passage 1003 is respectively communicated with the sixth opening 1106 and the eighth opening 1108 of the valve body 11, thereby allowing raw water to flow from the first opening 1101 of the valve body 11 into the valve cavity 110 of the valve body 11, then flows into the purification device 20 through the first communication passage 1001 formed by the plane valve 10, the fifth opening 1105 of the valve body 11, the first communication opening 201 of the purification device 20, and then flows out of the obtained purified water after the purification treatment of the purification device 20 from the second communication opening 202 of the purification device 20, and then the purified water is separated into two paths, wherein the purified water flows out of the second communication passage 1003 through the sixth opening 1106 and the eighth opening 11 of the valve body 11, and finally flows out to the user through the valve body 10 and the eighth opening 1108 of the valve body 11; the other clean water flows through the first through-opening 301 of the softening tank 31 into the softening tank 31, and is softened to obtain softened water, which flows out of the second through-opening 302 of the softening tank 31, flows through the seventh opening 1107 of the valve body 11 and the second through-passage 1002 of the plane valve 10, flows out of the second opening 1102 of the valve body 11, and is supplied to the user through a softened water supply passage 903. As shown in fig. 1A to 3A of the drawings, after flowing out through the second opening 1102 of the valve body 11, the softened water may further flow through the first solenoid valve water inlet 951 and the first solenoid valve water outlet 952 of the first solenoid valve 95, then enter the booster pump 92 through the pump water inlet 921 of the booster pump 92, the pressurized softened water flows out from the pump water outlet 922, then enters the reverse osmosis cartridge 91 through the membrane water inlet 911, then after reverse osmosis treatment through the reverse osmosis cartridge 91, reverse osmosis treated water (or pure water) is produced, the reverse osmosis treated water flows out from the membrane water outlet 912 of the reverse osmosis cartridge 91, the pure water produced after filtration of the reverse osmosis cartridge 91 flows into the water storage container 98 through the one-way valve water inlet 961 and the one-way valve water outlet 962 of the one-way valve 96, and then flows into the water storage container 98 through the container connection port 981 of the water storage container 98 for future use, or is directly provided to a user through the purified water outlet 902; the wastewater flowing out of the membrane wastewater port 913 flows into the wastewater restrictor 93 through the wastewater restrictor water inlet 931 of the wastewater restrictor 93, then flows out of the wastewater restrictor water outlet 932, and then flows out of the reverse osmosis water outlet 901. Accordingly, when it is required to rinse the reverse osmosis membrane of the reverse osmosis cartridge 91 of the reverse osmosis apparatus 90, softened water flows through the first solenoid valve water inlet 951 and the first solenoid valve water outlet 952 of the first solenoid valve 95, then enters the booster pump 92 through the pump water inlet 921 of the booster pump 92, pressurized softened water flows out of the pump water outlet 922, then enters the reverse osmosis cartridge 91 through the membrane water inlet 911, the rinsed wastewater of the reverse osmosis cartridge 91 flows out of the membrane water outlet 913 of the reverse osmosis cartridge 91, and the wastewater is split into two paths, wherein one path of wastewater flows into the wastewater restrictor 93 through the wastewater restrictor water inlet 931 of the wastewater restrictor 93, then flows out of the wastewater restrictor water outlet 932, then flows out of the reverse osmosis water outlet 901, and the other path of wastewater flows out of the wastewater control water outlet 942 through the wastewater control water inlet 941 of the wastewater control valve 94, then flows out of the wastewater restrictor water outlet 942. It is noted that when the waste control valve 94 is conducting, the flow rate of water through the waste control valve 94 is much greater than the flow rate of water through the waste restrictor 93. Thus, when the multifunctional water treatment machine is in the first operating state, the first opening 1101 of the valve body 11 of the planar valve 10, the valve inner chamber 110 of the valve body 11, the first communication passage 1001, the fifth opening 1105 of the valve body 11, the first communication opening 201 of the purification device 20, the second communication opening 202 of the purification device 20, the first communication opening 301 of the softening tank 31, the second communication opening 302 of the softening tank 31 form a purification-softening water path connecting the purification cartridge 21A of the purification device 20 and the softening tank 31 of the softening device 30 in series. When the multifunctional water treatment machine is in the first operating state, further, the first opening 1101 of the valve body 11, the valve inner chamber 110 of the valve body 11, the first communication channel 1001, the fifth opening 1105 of the valve body 11, the first communication opening 201 of the purification device 20, the second communication opening 202 of the purification device 20, the first communication opening 301 of the softening tank 31, the second communication opening 302 of the softening tank 31, the seventh opening 1107 of the valve body 11, the second communication channel 1002, the second opening 1102 of the valve body 11, the reverse osmosis device 90 form a purification-softening-reverse osmosis water treatment waterway connecting the purification cartridge 21A of the purification device 20, the softening tank 31 of the softening device 30 and the reverse osmosis cartridge 91 of the reverse osmosis device 90 in series. Optionally, the sixth opening 1106 of the valve body 11, the third communication passage 1003 and the eighth opening 1108 of the valve body 11 of the planar valve 10 further form a purified water supply branch to supply purified water to a user. Therefore, the multifunctional water treatment machine of the present invention can provide purified water and softened water to a user at the same time. Accordingly, the first operating state of the multi-functional water treatment machine corresponds to a water treatment operating state of the multi-functional water treatment machine. Thus, when the multifunctional water treating machine is in the first operating state, the first opening 1101 of the valve body 11 (or the valve inner chamber 110 of the valve body 11), the fifth opening 1105 of the valve body 11, the first communication opening 201 of the purification apparatus 20, the second communication opening 202 of the purification apparatus 20, the first communication opening 301 of the softening tank 31 of the softening apparatus 30, the second communication opening 302 of the softening tank 31 of the softening apparatus 30, the seventh opening 1107 of the valve body 11, and the second opening 1102 of the valve body 11 are sequentially communicated, thereby forming a water flow path connecting the purification apparatus 20 and the softening apparatus 30 in series, so that raw water can flow from the purification apparatus 20 to the softening apparatus 30 and be sequentially purified and softened. Meanwhile, the sixth opening 1106 of the valve body 11, the third communication passage 1003 of the plane valve 10, and the eighth opening 1108 of the valve body 11 form a purified water supply branch (waterway) to provide purified water to a user.

It should be noted that the control of the reverse osmosis treatment of softened water by the multifunctional water treatment machine according to the present invention can be achieved by the pressure sensor 97, wherein when the pressure of the pressure detecting water inlet 971 of the pressure sensor 97 is smaller than a preset starting pressure value, the multifunctional water treatment system controls to open the first electromagnetic valve 95 and start the booster pump 92 to produce reverse osmosis treated water (or pure water) through the reverse osmosis filter element 91, and the reverse osmosis treated water can be supplied to a user directly through the purified water outlet 902 or can be controlled to flow into the water storage container 98 for future use. Further, when the pressure of the pressure detecting water inlet 971 of the pressure sensor 97 is greater than a stop preset pressure value, the multifunctional water treatment system controls to close the first solenoid valve 95 and stop the pressurizing of the pressurizing pump 92, so that the multifunctional water treatment system stops preparing the reverse osmosis treated water. That is, when the user turns off the tap 99 or the water storage container 98 is full, causing the pressure of the pressure sensing water inlet 971 of the pressure sensor 97 to rise to the stop preset pressure value, the multifunctional water treatment system stops preparing reverse osmosis treated water.

As described above, water treatment systems, particularly domestic water treatment systems, typically use municipal tap water as a water source (or raw water) in which the calcium and magnesium ion concentrations are relatively high. Accordingly, when the reverse osmosis device, for example, a reverse osmosis cartridge, directly performs reverse osmosis treatment on raw water, a certain proportion of raw water is required to flush the reverse osmosis cartridge (or reverse osmosis membrane) and discharge the raw water so as to prevent corresponding compounds generated by calcium ions and magnesium ions from precipitating and scaling, thereby causing blockage of the reverse osmosis membrane and reduction of the service life of the reverse osmosis membrane. That is, the reverse osmosis device is required to perform the reverse osmosis treatment on the raw water, and the reverse osmosis filter element (or reverse osmosis membrane) of the reverse osmosis device is required to be flushed, and the higher the hardness of the raw water is, the more flushing water is required, the less reverse osmosis treatment water is produced from the raw water, and the more wastewater is discharged. The multifunctional water treatment system of the invention sequentially purifies and softens raw water before reverse osmosis treatment is carried out on the water, so that impurities such as calcium ions, magnesium ions and the like in the raw water are removed as much as possible, the hardness of the water entering a reverse osmosis membrane of a reverse osmosis device is effectively reduced, the amount of water for flushing the reverse osmosis membrane when the reverse osmosis device carries out reverse osmosis treatment on the water is reduced, and water resources are effectively saved. Preferably, the multifunctional water treatment system of the present invention controls the size of the water flow for washing the reverse osmosis membrane during the reverse osmosis treatment through the wastewater restrictor 93. When the hardness of the water reverse osmosis treated by the reverse osmosis device is low, a wastewater restrictor with smaller flow rate can be selected.

As shown in fig. 3A to 3G of the drawings, when the multifunctional water treatment machine according to the preferred embodiment of the present invention is in the second operating state, the fourth communication passage 1004 formed by the plane valve 10 is respectively communicated with the first opening 1101 and the seventh opening 1107 of the valve body 11, the fifth communication passage 1005 is respectively communicated with the sixth opening 1106 of the valve body 11 and the ninth opening 1109 of the plane valve 10, thereby allowing raw water to flow from the first opening 1101 of the valve body 11 into the valve cavity 110 of the valve body 11, then flows into the seventh opening 1107 through the fourth communication passage 1004 formed by the plane valve 10, flows into the softening tank 31 through the second communication opening 302 of the softening tank 31, and after back flushing of softened material (or water treatment material) such as softened resin, the obtained sewage or wastewater flows out of the first opening 301 of the softening tank 31, then flows out of the fifth communication passage 1005 from the fifth communication passage 1109 of the plane valve 10 through the sixth opening 1106 of the valve body 11. In other words, the multi-functional water treatment machine of the present invention can control the back flushing of the softening cartridge, such as the softening tank 31, when the multi-functional water treatment machine is in the second operating state. Correspondingly, the second working state of the multifunctional water treatment machine corresponds to a backwashing working state of a softening filter element (such as a softening tank of a softening device) of the multifunctional water treatment machine.

As shown in fig. 3A to 3G of the drawings, when the multifunctional water treatment machine according to the preferred embodiment of the present invention is in the third operating state, the sixth communication passage 1006 formed by the plane valve 10 is respectively communicated with the first opening 1101 and the sixth opening 1106 of the valve body 11, the seventh communication passage 1007 is respectively communicated with the fifth opening 1105 of the valve body 11 and the ninth opening 1109 of the plane valve 10, so as to allow raw water to flow from the first opening 1101 of the valve body 11 into the valve cavity 110 of the valve body 11, then flow into the sixth opening 1106 through the sixth communication passage 1006, and then flow into the second communication opening 202 of the purification apparatus 20, after the water treatment material or mechanism in the purification apparatus 20 is backwashed, flows out of the first communication opening 201 of the purification apparatus 20, then flows into the seventh communication passage 1007 through the fifth opening 1105 of the valve body 11, and then flows out of the ninth opening 1109 of the plane valve 10; correspondingly, the third working state of the multifunctional water treatment machine corresponds to the backwashing working state of the purifying device of the multifunctional water treatment machine.

Accordingly, the fourth operating state of the multi-functional water treatment machine corresponds to a regeneration operating state of a softening cartridge (e.g., a softening tank of a softening device) of the multi-functional water treatment machine.

As shown in fig. 3A to 3G of the drawings, when the multifunctional water treatment machine according to the preferred embodiment of the present invention is in the fifth operating state, the eleventh communication passage 10011 formed by the plane valve 10 is respectively communicated with the first opening 1101 and the sixth opening 1106 of the valve body 11, the twelfth communication passage 10012 is respectively communicated with the seventh opening 1107 of the valve body 11 and the ninth opening 1109 of the plane valve 10, so as to allow raw water to flow from the first opening 1101 of the valve body 11 into the valve cavity 110 of the valve body 11, then flow into the sixth opening 1106 through the eleventh communication passage 10011, then flow into the first conduction opening 301 of the softening tank 31, flow out of the second conduction opening 302 of the softening tank 31 after forward flushing of the water treatment material or mechanism in the softening tank 31, then flow through the seventh opening 1107 of the valve body 11 into the twelfth communication passage 10012, and then flow out of the ninth opening 1109 of the plane valve 10.
