Water treatment machine

Technical Field

Further, the utility model discloses water processor purifier (purification filter core) and softening installation (softening box) are all set up at the water processor, and are set up and can purify and soften the processing to raw water (or pending water) through single control valve, realization 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 for purifying 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 water purification-softening composite water treatment machines. The main reason is that the purification of water and the softening of water are different in mechanism or mechanism. When carrying out purification treatment to the water intaking, the user needs regularly to change the filter core to it loses purification performance to avoid purifying filter core 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 a period of water softening treatment by using the water softener, the water softener needs to periodically replenish salt solution (generally, NaCl solution) into a softening tank (which may also be a softening filter element 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. In addition, the water softener needs to be replenished with water into the salt (liquid) tank in addition to the salt liquid in the softening tank to prevent the salt liquid in the salt liquid tank from being exhausted and failing to supply the salt liquid into the softening tank. However, all water treatment machines involve control of the water flow. Due to the complexity of the structure and function realization of the water softener for softening water, the purification-softening composite water treatment machine needs to form a complex water path and can realize reasonable control on the complex water path. In order to realize the control of a purified water channel and a softened water channel at the same time, most of the existing purification-softening composite water treatment machines are provided with more than two control valves, which finally leads to the overstaffed structure, large volume and poor use experience of the whole water treatment machine. 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 purifying-softening composite water treatment machine has huge volume, occupies too much space and brings great inconvenience to the installation of users. Needless to say, maintenance and filter element replacement in the event of a malfunction of the water treatment machine. In addition, the existing purifying-softening composite water treatment machine rarely provides purified water to a user at the same time when softening water. Even more, there are purification-softening composite water treatment machines that supply only softened water, not purified water. The user has to access the purified water through an additional water purification mechanism. 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 purification-softening composite 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.

Therefore, when the fluid valve 10 is a flat valve, the spool 1 of the fluid valve 10 includes the movable valve plate 13 and the fixed valve plate 12. Furthermore, it can be understood that, since the inner cavity 110 of the valve body 11 of the flat valve 10 communicates with the first opening 1101, water to be treated is supplied through the first opening 1101 and the inner cavity 110.

As shown in fig. 1 to 30G of the drawings, the softening device 30 of the water treatment machine according to the preferred embodiment of the present invention further comprises an ejector 32 and a saline 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 saline solution tank 33 is adapted to communicate with the ejector 32, so that the saline solution from the saline solution tank 33 can pass through the ejector 32 and the fourth opening 1104 and flow to the softening tank 31 of the softening device 30 through the flat valve 10, thereby regenerating the softened resin in the softening tank 31. Correspondingly, when the water treatment machine of the present invention is in a softening filter element (or softening tank) for absorbing salt and regenerating operation, raw water or water to be treated flows into the inner cavity 110 of the valve body 11 from the first opening 1101 of the valve body 11, then flows into the third opening 1103 through an eighth communicating channel 1008, then flows into the ejection opening 321 of the ejector 32, flows through the ejector 32, mixes the liquid from the salt solution tank 33, then flows into the fourth opening 1104 of the valve body 11 through the ejection opening 322 of the ejector 32, then flows into the seventh opening 1107 through a ninth communicating channel 1009, enters the second communicating opening 302 of the softening tank 31, regenerates the water treatment material or mechanism in the softening tank 31 in a reverse flow manner, such as softened resin, flows out from the first communicating opening 301, then flows into a tenth communicating channel 10010 through the sixth opening 1106 of the valve body 11, and then out of a ninth opening 1109 of the planar valve 10. It is to be understood that although the present invention is described by way of example only as providing saline to the softening tank 31 through the ejector 32, saline may be provided to the softening tank 31 through the fourth opening 1104 of the face valve 10 by other means or mechanisms. Therefore, the manner of supplying the salt solution to the softening tank 31 through the ejector 32 should not be a limitation of the present invention.
