Multifunctional water treatment machine

Technical Field

The utility model relates to a water treatment technical field especially relates to a multifunctional water processor, wherein the utility model discloses multifunctional water processor can carry out purification treatment and softening treatment to water. Further, the utility model discloses multifunctional water processor can also carry out reverse osmosis treatment to water. Especially, the utility model discloses multi-functional water processor's purifier (purification filter core) and softening installation (softening box) all are set up at multi-functional water processor, and are set up and can purify and the softening treatment to raw water (or pending water) through single control valve, realize to make the user can obtain purified water and demineralized water simultaneously.

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.

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 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, and the second communicating opening 302 of the softening tank 31 form a purifying-softening water path connecting the purifying cartridge 21A of the purifying device 20 and the softening tank 31 of the softening device 30 in series.

Therefore, the utility model discloses multi-functional water processor can provide water purification and demineralized water simultaneously to the 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.

It is worth noting that the utility model discloses this pressure sensor 97 of control accessible of multi-functional water processor to the reverse osmosis treatment of demineralized water realizes, wherein when this pressure detection water inlet 971's of this pressure sensor 97 pressure is less than one and starts when presetting the pressure value, then this first solenoid valve 95 is opened, start this booster pump 92 to this multi-functional water processing system control, in order to make reverse osmosis treatment water (or pure water) through this reverse osmosis filter core 91, reverse osmosis treatment water can be directly provided for the user through this purified water delivery port 902, also can be controlled to flow in this water storage container 98, in order to be ready 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. And the utility model discloses multi-functional water treatment system purifies in proper order and softens the processing through carrying out reverse osmosis treatment to water before, to the raw water, detaches impurity such as calcium ion, magnesium ion in the raw water as far as possible, effectively reduces the hardness that gets into reverse osmosis unit's reverse osmosis membrane's water, reduces reverse osmosis unit and when carrying out reverse osmosis treatment to water, washes reverse osmosis membrane's water volume, effective water economy resource. Preferably, the multifunctional water treatment system controls the size of the water flow for flushing the reverse osmosis membrane through the wastewater flow restrictor 93 during reverse osmosis treatment. 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.
