Description

Technical Field

[0001] The present invention relates to the field of water treatment technology, and in particular to a water treatment machine, wherein the water treatment machine of the present invention can perform multi-stage softening treatment on water. Further, the water treatment machine of the present invention includes multiple softening devices, and is configured to achieve multi-stage softening treatment of raw water (or water to be treated) through a single control valve. Background Art

[0002] As people pay more and more attention to health and worry about water pollution, water treatment machines or water treatment systems have become common household appliances. Water treatment machines, especially household water treatment machines, such as central water purifiers and water softeners, are often installed in the kitchen to treat water and get cleaner water.

[0003] According to the different treatment methods of raw water or water to be treated, water treatment machines can generally be divided into water purifiers and water softeners. Common water purifiers, such as activated carbon filtration water purifiers, ultrafiltration water purifiers, RO membrane water purifiers, etc., are mostly used to remove impurities in water as much as possible, such as harmful substances and foreign matter with odor. The main purpose of water softeners is to remove calcium ions and other ions in water. The water obtained by treating raw water with water purifiers such as ultrafiltration water purifiers and RO membrane water purifiers is relatively cleaner and more suitable for drinking. The soft water obtained by treating raw water with water softeners contains less calcium ions, etc., which is more suitable for bathing, washing clothes, etc. Some people also believe that soft water is more suitable for beauty. However, most of the existing water treatment machines with composite water treatment functions are water treatment machines that simply purify water, such as activated carbon-ultrafiltration filtration composite water purification system, ultrafiltration-RO membrane composite water purification system, PP cotton-activated carbon composite water purification system, etc., but there are almost no softening composite water treatment machines. The main reason is that there is a big difference in the mechanism or mechanism of water purification and water softening. When purifying water, users need to replace the filter element regularly to prevent the purification filter element from losing its purification function after long-term use. For example, although flushing can extend the service life of the filter element, activated carbon filter elements and ultrafiltration filter elements still need to be replaced after long-term use. After softening the water, the water softener needs to regularly add salt solution (generally NaCl solution) to the softening box (or softening tank) and clean the softening box to avoid the softening resin in the softening box from losing its activity after long-term use and remove impurities in the softening box. In addition, in addition to adding salt solution to the softening box, the water softener also needs to add water to its salt (liquid) tank to prevent the salt solution in the salt solution tank from being exhausted and unable to provide salt solution to the softening tank. Generally, in practical applications, the service life of the softening resin significantly exceeds the service life of the filter element. Due to the complexity of the structure and function of the water softener for softening water, the softening composite water treatment machine needs to form a complex waterway in order to achieve reasonable control thereof. In order to achieve good control of the waterway of the softening composite water treatment machine, a complex waterway is required, which ultimately leads to the bloated structure, bulky volume and poor user experience of the entire water treatment machine. In addition, water treatment machines, especially household water treatment machines, are generally installed under the countertop of the kitchen, such as under the sink. The large volume of the existing softening composite water treatment machine takes up too much space and also brings great inconvenience to the user's installation. Not to mention the maintenance and filter element replacement when the water treatment machine fails. Finally, for safety reasons, water treatment equipment, especially water treatment machines with composite water treatment functions, need to continuously provide water (or raw water) in a non-water treatment working state. However, most existing softening composite water treatment machines can only provide soft water (or softened water) in a softening working state, and cannot continuously provide water in other working states, such as the cleaning working state of the softening filter element of the softening device.

The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0075] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0076] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0077] Referring to the accompanying drawings of the present invention Figures 1 to 18 A water treatment machine according to a preferred embodiment of the present invention is illustrated, which is suitable for softening raw water or water to be treated, wherein the water treatment machine includes at least one primary softening device 20, at least one secondary softening device 30 and a shell 50, the shell 50 forms an inner cavity 500, wherein the primary softening device 20 and the secondary softening device 30 are both arranged in the inner cavity 500 of the shell 50.

[0078] As shown in the attached picture Figures 1 to 18 As shown, the primary softening device 20 of the water treatment machine according to a preferred embodiment of the present invention includes at least one softening filter element 21A, and the secondary softening device 30 includes at least one softening filter element 31, wherein the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 are both arranged in the inner cavity 500 of the housing 50. Figure 2 and Fig.12 As shown, the water treatment machine further includes a salt liquid tank 33, wherein the salt liquid tank 33 is also arranged in the inner cavity 500 of the housing 50. It can be understood that the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 can be any softening mechanism or device that can place softening resin so as to soften water using softening resin. In other words, the shape, structure and form of the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 should not constitute a limitation to the present invention. Therefore, the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 can be any appropriate shape such as box-shaped, can-shaped or columnar. Preferably, the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 are glass fiber reinforced plastic tanks.

[0079] As shown in the attached picture Figures 1 to 18 As shown, preferably, when the water treatment machine of the present invention is in a first working state, the primary softening device 20 and the secondary softening device 30 are connected in series through a softening water path, so that the water treatment machine can sequentially soften the raw water or the water to be treated, thereby providing the user with softened water that has undergone multi-stage softening treatment. In other words, the first working state of the water treatment machine corresponds to its softening working state.

[0080] As shown in the attached picture Figures 1 to 18As shown, the water treatment machine according to a preferred embodiment of the present invention further includes a control valve 10, wherein when the water treatment machine is in the first working state, the softening filter element 21A of the primary softening device 20 of the water treatment machine and the softening filter element 31 of the secondary softening device 30 are connected in series through the control valve 10, so that the water treatment machine can sequentially soften the raw water or the water to be treated. It can be understood that when the water treatment machine is in the first working state, the softened water obtained by the softening filter element 21A of the primary softening device 20 of the water treatment machine flows to the secondary softening device 30 and the softened water obtained by the further softening treatment of the softening filter element 31 of the secondary softening device 30, and is provided to the user through a softened water supply waterway.

[0081] As shown in the attached picture Figures 1 to 18 As shown, the control valve 10 of the water treatment machine according to the preferred embodiment of the present invention is configured to control the water flow through the primary softening device 20 and the secondary softening device 30, thereby realizing the corresponding functions of the water treatment machine. Therefore, compared with the existing water treatment equipment, the complexity of the control mechanism of the water treatment machine of the present invention is significantly reduced and the volume of the water treatment machine can be made smaller and easier to use and install. In particular, the water treatment machine of the present invention can save the limited space of a small kitchen. Preferably, the control valve 10 of the water treatment machine according to the preferred embodiment of the present invention is arranged in the inner cavity 500 formed by the outer shell 50. More preferably, the control valve 10 is fixed to the inner wall of the outer shell 50.

[0082] As shown in the attached picture Figure 2 , Fig.12 and Fig.13 As shown, the softening filter element 31 of the secondary softening device 30 of the water treatment machine according to the preferred embodiment of the present invention can be detachably arranged in the inner cavity 500 of the housing 50, so as to facilitate the replacement of the softening filter element 31 of the secondary softening device 30. Preferably, the softening filter element 21A of the primary softening device 20 of the water treatment machine is also detachably arranged in the inner cavity 500 of the housing 50, so as to facilitate the replacement of the softening filter element 21A of the primary softening device 20. More preferably, the salt solution tank 33 of the water treatment machine of the present invention is detachably arranged in the inner cavity 500 of the housing 50, so as to facilitate the replacement of the salt solution tank 33.

[0083] As shown in the attached picture Figure 2 , Fig.12 and Fig.17As shown, the inner cavity 500 of the housing 50 of the water treatment machine according to a preferred embodiment of the present invention forms two first cavities 501 and a second cavity 502, wherein the second cavity 502 is arranged between the two first cavities 501. The softening filter element 21A of the primary softening device 20, the softening filter element 31 of the secondary softening device 30 and the salt solution tank 33 of the water treatment machine according to a preferred embodiment of the present invention are respectively arranged in the first cavity 501 and the second cavity 502 of the housing 50. Preferably, the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 are respectively arranged in the first cavity 501 of the housing 50, and the salt solution tank 33 is arranged in the second cavity 502. More preferably, the control valve 10 of the water treatment machine is arranged in the second cavity 502. That is to say, the control valve 10 and the salt solution tank 33 of the water treatment machine are arranged in the same cavity, the second cavity 502. Most preferably, the control valve 10 is arranged above the salt solution tank 33.

[0084] It is worth noting that the softening filter element 21A of the first-stage softening device 20, the softening filter element 31 of the second-stage softening device 30 and the brine tank 33 of the water treatment machine of the present invention are arranged to surround the control valve 10, so that the connection between the control valve 10 and the softening filter element 21A of the first-stage softening device 20, the softening filter element 31 of the second-stage softening device 30 and the brine tank 33 is more convenient to achieve and the structure of the water treatment machine of the present invention is more compact and integrated, so that the appearance of the water treatment machine of the present invention is more regular and has a smaller volume. In particular, when the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30 are respectively arranged in the two first chambers 501 of the housing 50, the salt solution tank 33 and the control valve 10 are respectively arranged in the second chamber 502, and the control valve 10 is arranged above the salt solution tank 33, the softening filter element 21A of the primary softening device 20 of the water treatment machine of the present invention, the softening filter element 31 of the secondary softening device 30 and the salt solution tank 33 are C-shaped and surround the control valve 10. The control valve 10 of the water treatment machine of the present invention is arranged above the salt solution tank 33, which is more convenient for manufacturers to achieve communication between the control valve 10 and the softening filter element 21A of the primary softening device 20, the softening filter element 31 of the secondary softening device 30 and the salt solution tank 33 and convenient for users to operate the control valve 10. For example, during the manufacturing process, the manufacturer may first set the softening filter element 21A of the primary softening device 20, the softening filter element 31 of the secondary softening device 30 and the salt solution tank 33 in the first cavity 501 and the second cavity 502, and then install the control valve 10. Secondly, when a water treatment machine, especially a water treatment machine controlled by a single valve, fails, it is very likely that the connecting pipeline between the control valve 10, the softening filter element 31 of the secondary softening device 30, the salt solution tank 33 and / or the softening filter element 21A of the primary softening device 20 fails. Therefore, the control valve 10 is arranged above the salt solution tank 33, which will be more convenient for users or after-sales to perform after-sales maintenance on the water treatment machine of the present invention. Again, the main working parts of the water treatment machine of the present invention are the softening filter element 21A of the primary softening device 20 and the softening filter element 31 of the secondary softening device 30.

Further, when the plane valve 10 is in the fourth working position, the water treatment machine according to the preferred embodiment of the present invention is controlled to be in the water replenishment working state, and the sixth channel 106 of the plane valve 10 is connected with the fifth channel 105 to form the seventh connecting channel 1007; when the plane valve 10 is in the fifth working position, the water treatment machine according to the preferred embodiment of the present invention is controlled to be in the regeneration working state, the sixth channel 106 of the plane valve 10 is connected with the fourth channel 104 to form the eighth connecting channel 1008, the seventh channel 107 of the plane valve 10 is respectively connected with the fifth channel 105 and the second channel 102 to form the ninth connecting channel 1009, and the eighth channel 108 of the plane valve 10 is connected with the first channel 101 to form the tenth connecting channel 10010. It can be understood that when the planar valve 10 is in the first working position, the seventh channel 107 of the planar valve 10 is respectively connected to the third channel 103 and the second channel 102, and the movable valve plate 13 of the planar valve 10 separates the third channel 103 from the valve cavity 110 of the valve body 11 to prevent the raw water in the valve cavity 110 of the valve body 11 from entering the third channel 103.

[0124] As shown in the attached picture FIG. 3A to FIG. 5EAs shown, further, when the plane valve 10 of the water treatment machine according to the preferred embodiment of the present invention is in the second working position, the third working position, the fourth working position and the fifth working position, the sixth opening 1106 of the plane valve 10 is connected with the third channel 103 of the valve body 11 (through the valve cavity 110 of the valve body 11), thereby forming the eleventh communication channel 10011. Accordingly, when the water treatment machine according to the preferred embodiment of the present invention is in the second working position, the third working position, the fourth working position and the fifth working position, raw water is allowed to flow from the sixth opening 1106 of the valve body 11 into the valve cavity 110 of the valve body 11, and further flow from the valve cavity 110 of the valve body 11 to the third opening 1103 of the valve body 11 through the third channel 103 of the fixed valve plate 12.

[0125] As shown in the attached picture FIG. 3A to FIG. 5EAs shown, correspondingly, when the plane valve 10 is in the first working position, the water treatment machine is in a softening working state, and the raw water flows from the sixth opening 1106 of the valve body 11 into the valve cavity 110 of the valve body 11, and then flows into the first channel 101 of the fixed valve plate 12 through the sixth channel 106 of the movable valve plate 13, and then enters the first communication opening 201 of the primary softening device 20 through the first opening 1101 of the valve body 11. After being softened by the water treatment material or mechanism of the primary softening device 20, the soft water flows out of the primary softening device 20. The second communicating opening 202 of the second softening device 30 flows out, then flows into the first communicating opening 301 of the softening filter element 31 of the secondary softening device 30, and after being further softened by the softening resin in the softening filter element 31, flows out from the second communicating opening 302 of the softening filter element 31, then flows through the second opening 1102 of the valve body 11 into the second channel 102 of the fixed valve plate 12, passes through the seventh channel 107 of the movable valve plate 13, and then is guided into the third channel 103 of the fixed valve plate 12, and then passes through the third opening 1103 of the valve body 11 to the user. The water treatment machine supplies softened water to the user; when the plane valve 10 is in the second working position, the water treatment machine is in the backwashing working state of the softening filter element, and the raw water flows into the valve cavity 110 of the valve body 11 from the sixth opening 1106 of the valve body 11, and then flows into the second channel 102 of the fixed valve plate 12 through the sixth channel 106 of the movable valve plate 13, and then flows into the softening filter element 31 through the second opening 1102 of the valve body 11 and the second communicating opening 302 of the softening filter element 31 of the secondary softening device 30, so as to soften the softening resin in the softening filter element 31. After backwashing, the resin flows out from the first communication opening 301 of the softening filter element 31, and then flows into the softening filter element 21A through the second communication opening 202 of the softening filter element 21A of the primary softening device 20. After backwashing the softened resin in the softening filter element 21A, the resin flows out from the first communication opening 201 of the softening filter element 21A, and sequentially flows through the first opening 1101 of the valve body 11, the first channel 101 of the fixed valve disc 12, and the eighth channel 108 of the movable valve disc 13, and flows out from the seventh opening 1107 of the plane valve 10.When the plane valve 10 is in the third working position, the water treatment machine is in the softening filter element forward washing working state, the raw water flows into the valve cavity 110 of the valve body 11 from the sixth opening 1106 of the valve body 11, then flows into the first channel 101 of the fixed valve plate 12 through the sixth channel 106 of the movable valve plate 13, and then enters the first communication opening 201 of the primary softening device 20 through the first opening 1101 of the valve body 11, and after the water treatment materials or mechanisms in the primary softening device 20 are forwardly washed, the raw water flows from the primary softening device 20 to the first softening device 20. The softening resin flows out from the second connecting opening 202 of the softening device 20, and then flows into the softening filter element 31 through the first connecting opening 301 of the softening filter element 31 of the secondary softening device 30. After forward flushing the softening resin in the softening filter element 31, it flows out from the second connecting opening 301 of the softening filter element 31, and then passes through the second opening 1102 of the valve body 11, enters the second channel 102 of the fixed valve plate 12, and then flows through the eighth channel 108 of the movable valve plate 13, and flows out from the seventh opening 1107 of the plane valve 10. Furthermore, when the plane valve 10 is in the fourth working position, the water treatment machine is in the water replenishment working state, and the raw water flows into the valve cavity 110 of the valve body 11 from the sixth opening 1106 of the valve body 11, and then flows into the fifth channel 105 of the fixed valve plate 12 through the sixth channel 106 of the movable valve plate 13, and then flows into the injection port 322 of the ejector 32 to replenish water to the brine tank 33. Further, when the plane valve 10 is in the fifth working position, the water treatment machine is in the regeneration working state, and the raw water flows from the sixth opening 1106 of the valve body 11 into the valve cavity 110 of the valve body 11, and then flows into the fourth channel 104 of the fixed valve plate 12 through the sixth channel 106 of the movable valve plate 13, and then flows into the fourth opening 1104, and then flows into the ejection port 321 of the ejector 32, and after being ejected by the ejector 32 and mixed with the liquid from the salt liquid tank 33, it flows into the fifth opening 1105 of the valve body 11 through the ejection port 322 of the ejector 32, and then enters the fifth channel 105 of the fixed valve plate 12, and then is guided into the seventh channel 107 of the movable valve plate 13. The second channel 102 then flows into the second opening 1102, enters the second communication opening 302 of the softening filter element 31 of the secondary softening device 30, reversely regenerates the softened resin in the softening filter element 31, flows out from the first communication opening 301 of the softening filter element 31, then flows into the second communication opening 202 of the softening filter element 21A of the primary softening device 20, reversely regenerates the softened resin in the softening filter element 21A, flows out from the first communication opening 301 of the softening filter element 21A, flows into the first channel 101 of the fixed valve plate 12 through the first opening 1101 of the valve body 11, then flows through the eighth channel 108 of the movable valve plate 13, and then flows out from the seventh opening 1107 of the plane valve 10. ;

[0126] Therefore, at each working position, the valve cavity 110 of the plane valve 10 of the water treatment machine according to the preferred embodiment of the present invention is respectively connected with the sixth opening 1106 and the sixth channel 106, so that the sixth opening 1106 of the plane valve 10 can be connected with the sixth channel 106 through the valve cavity 110, and different flow direction control of the water to be treated at each working position is realized. In addition, the seventh opening 1107 of the plane valve 10 of the water treatment machine according to the preferred embodiment of the present invention is used as a sewage opening, directly or indirectly connected to the eighth channel 108 of the plane valve 10, which can be formed in the valve body 11 of the plane valve 10, and can also be formed in a sewage channel.

[0127] As shown in the attached picture FIG. 5A to FIG. 5E As shown, preferably, when the planar valve 10 is in the first working position, the fourth channel 104 and the fifth channel 105 of the planar valve 10 are respectively closed by the movable valve plate 13; when the planar valve 10 is in the second working position, the fourth channel 104 and the fifth channel 105 of the planar valve 10 are respectively closed by the movable valve plate 13; when the planar valve 10 is in the third working position, the fourth channel 104 and the fifth channel 105 of the planar valve 10 are respectively closed by the movable valve plate 13; when the planar valve 10 is in the fourth working position, the fourth channel 104 of the planar valve 10 is closed by the movable valve plate 13.

[0128] It is worth noting that the first channel 101, the second channel 102, the third channel 103, the fourth channel 104 and the fifth channel 105 of the planar valve 10 are respectively and separately arranged on the first fluid control surface 120 of the fixed valve plate 12; the sixth channel 106, the seventh channel 107 and the eighth channel 108 are respectively and separately arranged on the second fluid control surface 130 of the movable valve plate 13. In other words, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104 and the fifth channel 105 of the planar valve 10 respectively form at least one channel opening of the first fluid control surface 120 arranged on the fixed valve plate 12, and the sixth channel 106, the seventh channel 107 and the eighth channel 108 respectively form at least one channel opening of the second fluid control surface 130 arranged on the movable valve plate 13. When the movable valve plate 13 of the planar valve 10 is arranged face to face (the second fluid control surface 130) with respect to (the first fluid control surface 120), and the movable valve plate 13 rotates relative to the fixed valve plate 12, the channel arranged on the movable valve plate 13 and the channel arranged on the fixed valve plate 12 are selectively connected through the corresponding channel openings, thereby forming corresponding connecting channels and controlling the flow direction of the fluid (such as water flow). Preferably, the second channel 102 forms two channel openings arranged on the first fluid control surface 120 of the fixed valve plate 12, wherein one channel opening of the second channel 102 is arranged between the channel opening of the first channel 101 and the channel opening of the fifth channel 105, and the other channel opening is arranged between the channel opening of the fourth channel 104 and the channel opening of the third channel 103.

[0129] It can be understood that the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106, the seventh channel 107 and the eighth channel 108 of the plane valve 10 can have any extension path (or direction) that can achieve the interconnected relationship described herein; the first channel 101, the second channel 102, the third channel 103, the fourth channel 104 and the fifth channel 105 of the plane valve 10 are respectively formed at the channel opening of the first fluid control surface 120 of the fixed valve plate 12, and the sixth channel 106, the seventh channel 107 and the eighth channel 108 are respectively formed at the channel opening of the second fluid control surface 130 of the movable valve plate 13, and can have any shape that can achieve the interconnected relationship described herein. For example, the channel opening of the first channel 101 formed at the first fluid control surface 120 of the fixed valve plate 12 can be set to have a regular shape, or can be set to have an irregular shape. Therefore, the extension paths (or directions) of the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106, the seventh channel 107 and the eighth channel 108 of the planar valve 10 and the shapes of their channel openings should not be limitations to the present invention.

[0130] As shown in the attached picture FIG. 4A to FIG. 5E and 6A to 6FAs shown, preferably, the passage in this article is closed, which means that the passage openings of the corresponding passages formed on the first fluid control surface 120 of the fixed valve disc 12 of the plane valve 10 and the second fluid control surface 130 of the movable valve disc 13 are covered by the entity part of the movable valve disc 13 or the fixed valve disc 12 at the specific working position of the plane valve 10 (or the working state of the water treatment machine), so that the corresponding passages cannot be connected through the passage openings. For example, when the plane valve 10 is in the first working position, the entity part of the movable valve disc 13 is directly opposite to the passage openings of the fourth passage 104 and the fifth passage 105 of the plane valve 10 formed on the first fluid control surface 120 of the fixed valve disc 12, so that the fourth passage 104 and the fifth passage 105 of the plane valve 10 are closed (or blocked) by the movable valve disc 13. Accordingly, the communication between the channel provided on the movable valve plate 13 and the channel provided on the fixed valve plate 12 herein refers to that in a specific working position (or working state of the water treatment machine) of the plane valve 10, the channel opening of the second fluid control surface 130 formed by the channel provided on the movable valve plate 13 and the channel opening of the first fluid control surface 120 formed by the channel provided on the fixed valve plate 12 are selectively partially or exactly aligned and form a water flow passage allowing water to flow through.
