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 which can purify and soften water. Furthermore, the multifunctional water treatment machine can also perform reverse osmosis treatment on water. In particular, the purification device (purification cartridge) and the softening device (softening tank) of the multi-functional water processor of the present invention are provided at the multi-functional water processor and are configured to enable purification and softening of raw water (or water to be treated) through a single control valve, thereby enabling a user to obtain purified water and softened water at the same time.

Background

With the increasing health concern and water pollution concern, water treatment machines or systems have become common household appliances. Water treatment machines, especially household 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 treatment machines are generally classified into water purification machines and water softening machines 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 mostly used for removing impurities, such as harmful substances and foreign substances with peculiar smell, in water as much as possible. And the water softener is mainly used for removing calcium ion plasma in water. Purifier such as ultrafiltration purifier and RO membrane purifier handle the water phase that the raw water obtained relatively cleaner and be fit for drinking, and the water softener handles the soft water that the raw water obtained because contain less calcium ion etc. more be fit for shower, wash clothes etc.. It is also believed that soft water is more suitable for cosmetic purposes. However, most of the existing water treatment machines having a composite water treatment function are water treatment machines which purify water only, 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, and the like, but there are almost few multifunctional water treatment machines which purify and soften water, not to mention multifunctional water treatment machines which purify, soften, and reverse osmosis treat water (or RO membrane treat water). The main reason is that there are great differences in the mechanism or mechanisms for water purification, softening and reverse osmosis treatment. When carrying out purification treatment to water, the user needs regularly to change the filter core to the purification filter core loses purification performance after long-time the use. For example, although flushing or the like can extend the useful life of the filter element, the activated carbon filter element and the ultrafiltration filter element need to be replaced after a long period of use. After water is softened, the water softener needs to periodically replenish salt solution (generally, NaCl solution) into a softening tank (or a softening tank) and clean the softening tank, so as to prevent the softened resin in the softening tank from losing activity and removing impurities in the softening tank after long-term use. When the RO membrane for reverse osmosis is poor in water quality, membrane blockage is easy to occur and the service life of the RO membrane is shortened when the water is subjected to reverse osmosis treatment. For example, when the hardness of water to be treated by reverse osmosis is too high, it is easy to cause clogging of the RO membrane and decrease of the reverse osmosis treatment capacity thereof. In addition, in practical application, the service life of the softening resin obviously exceeds that of the filter element. Therefore, in the course of water softening treatment, the water softener needs to be supplemented with water into the salt (liquid) tank in addition to the salt solution in the softening tank in order to prevent the salt solution in the salt solution tank from being exhausted and unable to be supplied into the softening tank. However, all of the water treatment functions of the water treatment machine described above are achieved in relation to the control of the water flow. Due to the complexity of the structure and function implementation of water softeners for softening water, a water treatment machine with the functions of purifying and softening water needs to form a complicated water path and can reasonably control the water path. In order to realize the control of a purified water passage and a softened water passage at the same time, most of the conventional multifunctional water treatment machines are provided with more than two control valves, which finally leads to the overstaffed, large volume and poor use experience of the whole water treatment machine mechanism. The structure of the multifunctional water treatment machine capable of purifying, softening and reverse osmosis treatment (or RO membrane treatment) of water is necessarily more complicated. Furthermore, water treatment machines, especially domestic water treatment machines, are typically mounted under the counter of a kitchen, such as under a hand sink. The existing multifunctional water treatment machine has huge volume, occupies too much space and brings great inconvenience to the installation of a user. Needless to say, maintenance and filter element replacement in the event of a malfunction of the water treatment machine. In addition, the existing multifunctional water treatment machine rarely provides purified water to a user at the same time when softening water. Even more, some of the water treatment machines for purification and softening supply only softened water, not purified water. The user has to get purified water again through an additional water purifier. Finally, for safety reasons, it is necessary for water treatment facilities, particularly water treatment machines having multiple 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 or/and softened water at the purification or/and softening functional position, and can not provide water continuously in other working states, such as the cleaning working state of the purification filter element of the purification device.

As shown in fig. 1A to 19 of the drawings, preferably, when the multifunction water processor of the present invention is in a first operation state, the purification device 20 and the softening device 30 are connected in series through a purification-softening water path so that the multifunction water processor can sequentially purify and soften raw water or water to be treated, thereby providing a user with purified water subjected to purification treatment and softened water obtained by further softening the purified water. In other words, the first operating state of the multifunction water processor corresponds to its water processing operating state. Preferably, the softening tank 31 of the softening device is a glass reinforced plastic tank. It can be understood that, when the multi-function water treatment machine of the present invention is in the first operating state, since the membrane water inlet 911 of the reverse osmosis filter core 91 of the reverse osmosis device 90 is communicated with the second opening 1102 of the valve body 11, the reverse osmosis filter core 91 of the reverse osmosis device 90 and the purification-softening water circuit are connected in series, and the softened water obtained from the multi-function water treatment machine can be further treated by the reverse osmosis filter core 91 of the reverse osmosis device 90 and reverse osmosis treated water can be obtained. In other words, the first operating state of the multifunction water processor of the present invention corresponds to its water processing operating state. At this time, the multi-functional water treatment machine of the present invention can treat raw water and obtain purified water, softened water and reverse osmosis treated (post) water.

It is noted that the reverse osmosis treated water of the multi-function water processor of the present invention is derived from reverse osmosis treatment of softened water thereof. The softened water obtained by softening the raw water (or the purified water prepared from the raw water) is further subjected to reverse osmosis treatment to prepare reverse osmosis treated water, so that the water obtaining rate of the reverse osmosis treated water can be improved, and the discharge of waste water is reduced. In addition, the softened water obtained after the softening treatment is further subjected to reverse osmosis treatment to prepare reverse osmosis treated water, and compared with the method of directly subjecting raw water to reverse osmosis treatment, the softened water can further reduce the damage of impurities in the raw water, such as calcium ions and magnesium ions, on a reverse osmosis membrane (or RO membrane), thereby prolonging the service life of the reverse osmosis membrane.

As shown in fig. 1A to 19 of the drawings, the multi-function water treatment machine according to the preferred embodiment of the present invention further includes a control valve 10, wherein the purification cartridge 21A of the purification apparatus 20 and the softening tank 31 of the softening apparatus 30 of the multi-function water treatment machine are connected in series through the control valve 10 when the multi-function water treatment machine is in the first operation state, so that the multi-function water treatment machine can sequentially purify and soften raw water or water to be treated.

In other words, although the purified water obtained by purifying the raw water by the purifying device 20 of the multi-function water processor of the present invention can be supplied through the purified water supply waterway, the purified water obtained by purifying the raw water by the purifying device 20 is used only for softening and generating softened water when the purified water supply waterway is not provided or is closed.

As shown in fig. 1A to 19 of the drawings, the control valve 10 of the multi-function water processor according to the preferred embodiment of the present invention is configured to control water flow to selectively flow through the purification device 20 and/or the softening device 30, thereby performing the corresponding functions of the multi-function water processor. That is, both the purification apparatus 20 and the softening apparatus 30 can perform the purification-softening treatment of water by a single control valve 10. Therefore, the control mechanism of the multi-function water treatment machine of the present invention is remarkably reduced in complexity and the volume of the multi-function water treatment machine can be made smaller and is convenient to use and install, compared with the existing water treatment facilities. Particularly, the multifunctional water processor can save the limited space of a narrow kitchen. Preferably, the control valve 10 of the multi-function water treatment machine according to the preferred embodiment of the present invention is disposed in the inner chamber 500 formed by the housing 50. More preferably, the control valve 10 is fixed to the inner wall of the housing 50.

More preferably, the salt tank 33 of the softening device 30 is detachably disposed in the inner cavity 500 of the housing 50, so as to facilitate replacement of the salt tank 33 of the softening device 30.

As shown in fig. 2 and 13 of the drawings, the inner cavity 500 of the housing 50 of the multifunction water processor according to the preferred embodiment of the present invention forms two first cavities 501 and a second cavity 502, wherein the second cavity 502 is disposed between the two first cavities 501. As shown in fig. 2 and 13 of the drawings, the purification cartridge 21A of the purification apparatus 20, the softening tank 31 of the softening apparatus 30 and the salt solution tank 33 of the multifunction water processor according to the preferred embodiment of the present invention are respectively disposed in the second cavity 502 and the first cavity 501 of the housing 50. Preferably, the purification cartridge 21A of the purification device 20 and the softening tank 31 of the softening device 30 are respectively disposed in the first cavity 501 of the housing 50, and the salt tank 33 of the softening device 30 is disposed in the second cavity 502. More preferably, the control valve 10 of the multi-function water treatment machine is provided in the second chamber 502. That is, the control valve 10 of the multi-function water treatment machine and the salt solution tank 33 of the softening device 30 are disposed in the same chamber, the second chamber 502. Most preferably, the control valve 10 is arranged above the salt liquid tank 33 of the softening device 30.

It is to be noted that the purification cartridge 21A of the purification apparatus 20, the softening tank 31 of the softening apparatus 30 and the salt tank 33 of the multifunction water processor of the present invention are disposed around the control valve 10, so that the communication between the control valve 10 and the purification cartridge 21A of the purification apparatus 20, the softening tank 31 of the softening apparatus 30 and the salt tank 33 is more conveniently achieved and the structure of the multifunction water processor of the present invention is more compact and integrated, thereby making the appearance of the multifunction water processor of the present invention more regular and having a smaller volume.

The control valve 10 of the multi-functional water treatment machine of the present invention is disposed above the salt tank 33 of the softening device 30, which is more convenient for a manufacturer to realize the communication between the control valve 10 and the purification cartridge 21A of the purification device 20, the softening tank 31 of the softening device 30 and the salt tank 33 and to operate the control valve 10 by a user. For example, during the manufacturing process, the manufacturer can first set the purification cartridge 21A of the purification apparatus 20, the softening tank 31 of the softening apparatus 30 and the salt tank 33 in the first cavity 501 and the second cavity 502, and then install the control valve 10. Secondly, in the event of a malfunction of a multifunction water treatment machine, in particular a multifunction water treatment machine controlled by a single valve, there is a high probability that the control valve 10, the control valve 10 and the communication lines between the softening tank 31 and the salt solution tank 33 of the softening device 30 and/or the purification cartridge 21A of the purification device 20 malfunction. Therefore, the control valve 10 is disposed above the salt solution tank 33 of the softening device 30, which is more convenient for users or after-sales maintenance of the multi-function water treatment machine of the present invention. Again, the main working components of the multi-function water treatment machine of the present invention are the purification cartridge 21A of the purification apparatus 20 and the softening tank 31 of the softening apparatus 30. When the purification cartridge 21A of the purification apparatus 20 and the softening tank 31 of the softening apparatus 30 are respectively disposed at both sides of the control valve 10 and the salt solution tank 33, the multi-function water treatment machine of the present invention allows a manufacturer to increase the volumes of the purification cartridge 21A of the purification apparatus 20 and the softening tank 31 of the softening apparatus 30 as much as possible, thereby increasing the purification and softening capacities of the purification cartridge 21A of the purification apparatus 20 and the softening tank 31 of the softening apparatus 30. Finally, the purifying filter element 21A of the purifying device 20 and the softening tank 31 of the softening device 30 are respectively arranged at two sides of the control valve 10 and the salt solution tank 33, and further, the gravity center of the multifunctional water treatment machine is closer to the structural center, even coincides with the structural center, so that the multifunctional water treatment machine is more stable and is not easy to fall down when being placed on the ground.

Furthermore, 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 supplied through the first opening 1101 and the valve inner chamber 110.

As shown in fig. 1A to 3G of the drawings, when the multifunctional water treatment machine according to the preferred embodiment of the present invention is in the first operating state, the first communication channel 1001 formed by the flat valve 10 is respectively communicated with the first opening 1101 and the fifth opening 1105 of the valve body 11, the second communication channel 1002 is respectively communicated with the second opening 1102 and the seventh opening 1107 of the valve body 11, the third communication channel 1003 is respectively communicated with the sixth opening 1106 and the eighth opening 1108 of the valve body 11, so as to allow raw water to flow into the valve cavity 110 of the valve body 11 from the first opening 1101 of the valve body 11, then flow into the purifying device 20 through the first communication channel 1001 formed by the flat valve 10, the fifth opening 1105 of the valve body 11 and the first communication opening of the purifying device 20, raw water purified by the purifying device 20 flows out of the second communication opening 202 of the purifying device 20, then the purified water is divided into two paths, wherein one path of purified water flows through the sixth opening 1106 of the valve body 11, the third communicating channel 1003 of the flat valve 10, and finally flows out through the eighth opening 1108 of the valve body 11 and supplies purified water to the user; the other path of purified water flows into the softening tank 31 through the first communicating opening 301 of the softening tank 31 and is softened to obtain softened water, the softened water flows out from the second communicating opening 302 of the softening tank 31, then flows through the seventh opening 1107 of the valve body 11 and the second communicating channel 1002 of the flat valve 10, then flows out through the second opening 1102 of the valve body 11, and is provided to the user through a softened water supply passage 903. As shown in fig. 1A to 3A of the drawings, 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 after flowing out through the second opening 1102 of the valve body 11, and 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 filter 91 through the membrane water inlet 911, and then is subjected to reverse osmosis treatment by the reverse osmosis filter 91 to obtain reverse osmosis treated water (or pure water), the reverse osmosis treated water flows out from the membrane water outlet 912, the wastewater generated by the reverse osmosis filter 91 flows out from the membrane wastewater outlet 913 of the reverse osmosis filter 91, the pure water generated by filtration by the reverse osmosis filter 91 flows into the water storage tank 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 tank 98 through the tank connecting port 981 of the water storage tank 98, for future use or provided directly to the 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 restricting inlet 931 of the wastewater restrictor 93, then flows out of the wastewater restricting outlet 932, and flows out of the reverse osmosis drain 901. Accordingly, when it is required to flush a reverse osmosis membrane of the reverse osmosis filter core 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 and then enters 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 and then enters the reverse osmosis filter core 91 through the membrane water inlet 911, flushed wastewater for flushing a reverse osmosis membrane flows out from the membrane wastewater outlet 913 of the reverse osmosis filter core 91, the wastewater is divided into two paths, one of the wastewater flows into the wastewater restrictor 93 through the wastewater flow-limiting water inlet 931 of the wastewater restrictor 93 and then flows out from the wastewater flow-limiting water outlet 932 and then flows out from the reverse osmosis water outlet 901, the other of the wastewater flows into the wastewater control valve 94 through the wastewater control water inlet 941 of the wastewater control valve 94, and then out through the waste water control outlet 942 and out through the reverse osmosis drain 901. It is noted that when the waste water control valve 94 is turned on, the flow rate of water passing through the waste water control valve 94 is much greater than the flow rate of water passing through the waste water restrictor 93. Therefore, when the multifunction water processor is in the first operating state, the first opening 1101 of the valve body 11 of the flat valve 10, the valve inner cavity 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 apparatus 20, the second communication opening 202 of the purification apparatus 20, the first communication opening 301 of the softening tank 31, and the second communication opening 302 of the softening tank 31 form a purification-softening water path connecting the purification cartridge 21A of the purification apparatus 20 and the softening tank 31 of the softening apparatus 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 of the flat valve 10, the valve inner cavity 110 of the valve body 11, the first communicating channel 1001, the fifth opening 1105 of the valve body 11, the first communicating opening 201 of the purifying device 20, the second communicating opening 202 of the purifying device 20, the first communicating opening 301 of the softening tank 31, the second communicating opening 302 of the softening tank 31, the seventh opening 1107 of the valve body 11, the second communicating channel 1002, the second opening 1102 of the valve body 11, and the reverse osmosis device 90 form a purifying-softening-reverse osmosis water treatment waterway connecting the purifying filter element 21A of the purifying device 20, the softening tank 31 of the softening device 30, and the reverse osmosis filter element 91 of the reverse osmosis device 90 in series. Optionally, the sixth opening 1106 of the valve body 11, the third communication channel 1003 and the eighth opening 1108 of the valve body 11 of the planar valve 10 further form a clean water supply branch to supply clean water to a user. Therefore, the multifunctional water processor of the present invention can simultaneously provide purified water and softened water to a user. Accordingly, the first operating state of the multifunction water processor corresponds to a water processing operating state of the multifunction water processor. Therefore, when the multifunction water processor 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 purifying device 20, the second communication opening 202 of the purifying device 20, the first communication opening 301 of the softening tank 31 of the softening device 30, the second communication opening 302 of the softening tank 31 of the softening device 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 raw water flow path connecting the purifying device 20 and the softening device 30 in series, so as to enable the raw water to flow from the purifying device 20 to the softening device 30 and to be sequentially purified and softened. Meanwhile, the sixth opening 1106 of the valve body 11, the third communication passage 1003 of the planar valve 10 and the eighth opening 1108 of the valve body 11 form a purified water supply branch (water path) to provide purified water to a user.

It should be noted that the control of the multi-function water treatment machine for reverse osmosis treatment of softened water can be realized by the pressure sensor 97, wherein when the pressure of the pressure detection water inlet 971 of the pressure sensor 97 is smaller than a starting preset pressure value, the multi-function 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 core 91, and the reverse osmosis treated water can be directly provided to a user through the purified water outlet 902 and can also be controlled to flow into the water storage container 98 for future use. Further, when the pressure of the pressure detection 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 electromagnetic valve 95 and stop the pressurization of the booster pump 92, so that the multifunctional water treatment system stops preparing the reverse osmosis treated water. That is, when the user turns off the water tap 99 or the water storage tank 98 is full, causing the pressure of the pressure detection inlet 971 of the pressure sensor 97 to rise to the stop preset pressure value, the multi-functional water treatment system stops preparing reverse osmosis treated water.

As mentioned above, water treatment systems, especially domestic water treatment systems, typically use municipal tap water as the water source (or raw water) and have relatively high concentrations of calcium and magnesium ions. Accordingly, when a reverse osmosis apparatus, for example, a reverse osmosis filter element, directly performs reverse osmosis treatment on raw water, a certain proportion of raw water is required to flush the reverse osmosis filter element (or reverse osmosis membrane) and be discharged so as not to cause precipitation and scaling of corresponding compounds generated from calcium ions and magnesium ions, which results in clogging of the reverse osmosis membrane and reduction in the service life of the reverse osmosis membrane. That is, the reverse osmosis unit performs reverse osmosis treatment on raw water simultaneously with washing of a reverse osmosis filter element (or a reverse osmosis membrane) of the reverse osmosis unit, and the higher the hardness of the raw water is, the more washing water is required, the less reverse osmosis treated water is produced from the raw water, and the more wastewater is discharged. The multifunctional water treatment system sequentially purifies and softens the raw water before the reverse osmosis treatment of 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 the reverse osmosis membrane of the reverse osmosis device is effectively reduced, the amount of the water for flushing the reverse osmosis membrane when the reverse osmosis device performs the reverse osmosis treatment on the water is reduced, and the water resource is effectively saved. Preferably, the multi-functional water treatment system of the present invention controls the amount of water flow for flushing the reverse osmosis membrane at the time of reverse osmosis treatment through the waste water restrictor 93. When the hardness of the water treated by reverse osmosis of the reverse osmosis device is low, a waste water flow restrictor with a small 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 operation state, the fourth communication channel 1004 formed by the flat valve 10 is respectively communicated with the first opening 1101 and the seventh opening 1107 of the valve body 11, the fifth communication channel 1005 is respectively communicated with the sixth opening 1106 of the valve body 11 and the ninth opening 1109 of the flat valve 10, so as to allow raw water to flow into the valve inner chamber 110 of the valve body 11 from the first opening 1101 of the valve body 11, then flow into the seventh opening 1107 through the fourth communication channel 1004 formed by the flat valve 10, flow into the softening tank 31 through the second communication opening 302 of the softening tank 31, and reversely flush softened materials (or water treatment materials) such as softened resins and the like in the softening tank 31, and the obtained sewage or wastewater flows out of the first communication opening 301 of the softening tank 31, then flows through the sixth opening 1106 of the valve body 11 into the fifth communication passage 1005 of the planar valve 10 and then flows out of the ninth opening 1109 of the planar valve 10. In other words, the multipurpose water processor of the present invention can control the reverse flushing of the softening cartridge, such as the softening tank 31, when the multipurpose water processor is in the second operation state. Accordingly, the second operating state of the multifunction water processor corresponds to a backwashing operating state of a softening filter element (such as a softening tank of a softening device) of the multifunction water processor.

When the multifunction water processor according to the preferred embodiment of the present invention is in the fourth operating state, the eighth communicating channel 1008 formed by the flat valve 10 is respectively communicated with the first opening 1101 and the third opening 1103 of the valve body 11, the ninth communicating channel 1009 is respectively communicated with the seventh opening 1107 and the fourth opening 1104 of the valve body 11, the tenth communicating channel 10010 is respectively communicated with the sixth opening 1106 of the valve body 11 and the ninth opening 1109 of the flat valve 10, so as to allow raw water to flow from the first opening 1101 of the valve body 11 into the valve inner cavity 110 of the valve body 11, then flow into the third opening 1103 through the eighth communicating channel 1008, then flow into the jet outlet 321 of the jet injector 32, flow through the jet injector 32, mix liquid from the salt liquid tank 33, and then flow into the fourth opening 1104 of the valve body 11 through the jet inlet 322 of the jet injector 32, then flows into the seventh opening 1107 through the ninth communication passage 1009, enters the second communication opening 302 of the softening tank 31, regenerates the softened resin in the softening tank 31 in a counter-flow manner, flows out from the first communication opening 301, then flows into the tenth communication passage 10010 through the sixth opening 1106 of the valve body 11, and then flows out from the ninth opening 1109 of the flat valve 10. Accordingly, the fourth operating state of the multifunction water processor corresponds to a regeneration operating state of a softening filter element (such as a softening box of a softening device) of the multifunction water processor.

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 channel 10011 formed by the flat valve 10 is respectively communicated with the first opening 1101 and the sixth opening 1106 of the valve body 11, and the twelfth communication channel 10012 is respectively communicated with the seventh opening 1107 of the valve body 11 and the ninth opening 1109 of the flat valve 10, so as to allow raw water to flow into the valve cavity 110 of the valve body 11 from the first opening 1101 of the valve body 11, then flow into the sixth opening 1106 through the eleventh communication channel 10011, then flow into the first communication opening 301 of the softening tank 31, flush the water treatment material or mechanism in the softening tank 31, flow out from the second communication opening 302 of the softening tank 31, then flow into the twelfth communication channel 10012 through the seventh opening 1107 of the valve body 11, and then out of the ninth opening 1109 of the planar valve 10.
