Description

Water treatment system, water treatment method and plane valve thereof
Technical Field
The invention relates to the technical field of water treatment, in particular to a water treatment system capable of carrying out multistage treatment on water, such as secondary purification or softening treatment on purified water so as to obtain cleaner purified water or softened water. Further, the water treatment system can be controlled to achieve multistage treatment of raw water (or water to be treated) by a single control valve, such as a fluid valve. Preferably, the control valve of the water treatment system of the present invention is a planar valve.
Technical Field
With increasing health concerns and concerns about water pollution problems, water treatment machines or 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.
In order to obtain sufficiently clean water, such as water more suitable for direct drinking, existing water treatment systems often have more than one filter element, such as many households that may install a pre-filter upstream of the ultrafiltration purifier to filter larger impurities, or an activated carbon filter element downstream of the ultrafiltration purifier to improve the mouthfeel of the purified water. For another example, a pre-filter is installed upstream of a water softener that softens water to remove larger impurities. However, the existing water treatment machines or water treatment systems with composite water treatment functions or multi-stage water treatment functions, such as an active carbon-ultrafiltration filtration composite water purification system, an ultrafiltration-RO membrane composite water purification system, a PP cotton-active carbon composite water purification system and the like, all require a plurality of control valves to realize flow control and water treatment control of water flow. The main reason is that when water is treated by a water treatment system with a multi-stage water treatment function, the water treatment system is required to provide not only the water treatment function but also other functions, such as back flushing of a filter element, particularly a pre-filter, after a period of use. However, water treatment systems perform these additional but important functions, both involving control of water flow and complex waterways. In order to realize the control of complex waterways, most existing water treatment machines with multi-stage water treatment functions have to be provided with two or more control valves, which ultimately results in the complex structure, huge volume and poor use experience of the whole water treatment system. Furthermore, water treatment machines, particularly domestic water treatment machines, are typically mounted under kitchen countertops, such as under a sink. The existing water treatment machine with the multi-stage water treatment function has huge volume, occupies excessive space and brings great inconvenience to the installation and use of users. In particular, the difficulty of a user operating the water treatment machine is increased when maintenance and cartridge replacement are required in the event of a failure of the water treatment system.

As shown in fig. 8A to fig. 13A and fig. 15A of the drawings, when the water treatment system according to the first preferred embodiment of the present invention is in the first operation state, the first communication passage 1001 formed by the plane valve 10 is respectively communicated with the first opening 1101 and the sixth opening 1106 (or the inner chamber 110) of the valve body 11, the second communication passage 1002 is respectively communicated with the second opening 1102 and the third opening 1103 of the valve body 11, the third communication passage 1003 is respectively communicated with the fourth opening 1104 and the fifth opening 1105 of the valve body 11, so that raw water is allowed to flow from the sixth opening 1106 of the valve body 11 into the inner chamber 110 of the valve body 11, and then flows into the first water treatment device 20 through the first communication passage 1001 of the plane valve 10, the first opening 1101 of the valve body 11 and the first communication opening 201 of the first water treatment device 20, and after passing through the purification (or treatment) of the first water treatment device 20, and then flows out of the second communication passage 10 through the first communication passage 10, the second communication passage 1003 of the second water treatment device 10 and the second communication passage 10 through the second opening 10 of the valve body 10, and the second communication passage 10 through the second communication passage 10 and the second communication passage 10 of the second communication passage 10 and the second communication passage 10 through the second opening 10 of the valve body 10 and the second communication passage 10, the second communication passage 10 and the second communication passage 10 through the first communication passage 10 and the first communication opening 10 and the valve opening 10 of the valve body 10 and the valve body opening 30, respectively. Accordingly, the first operating state of the water treatment system corresponds to a water treatment operating state of the water treatment system. Thus, when the water treatment system is in the first operating state, the sixth opening 1106 (or the inner chamber 110) of the valve body 11, the first opening 1101 of the valve body 11, the first communication opening 201 of the first water treatment device 20, the second communication opening 202 of the first water treatment device 20, the second opening 1102 of the valve body 11, the third opening 1103 of the valve body 11, the first communication opening 301 of the second water treatment device 30, the second communication opening 302 of the second water treatment device 30, the fourth opening 1104 of the valve body 11 and the fifth opening 1105 of the valve body 11 are sequentially communicated, thereby forming a water flow path connecting the first water treatment device 20 and the second water treatment device 30 in series, so that raw water can flow from the first water treatment device 20 to the second water treatment device 30 and be sequentially treated by the first water treatment device 20 and the second water treatment device 30. The direction of the arrow in fig. 13A indicates the direction of water flow.

In other words, the water treatment system of the present invention controls the back flushing of the second water treatment device 30 when the water treatment system is in the second operating state. Accordingly, in the second operating state of the water treatment system, the planar valve 10 of the water treatment system controls water flow to back flush the second filter element 31 of the second water treatment device 30, and thus the second operating state of the water treatment system corresponds to a second filter element backwash operating state of the water treatment system.

The direction of the arrow in fig. 13B indicates the direction of water flow.
Preferably, the twelfth communication passage 10012 formed by the plane valve 10 communicates with the fifth opening 1105 and the sixth opening 1106 (or the inner chamber 110) of the valve body 11, respectively, thereby allowing raw water to flow from the sixth opening 1106 of the valve body 11 into the inner chamber 110 of the valve body 11, and then the twelfth communication passage 10012 formed by the plane valve 10 flows out through the fifth opening 1105 of the valve body 11 and supplies raw water to a user. That is, when the water treatment system is in the second operating state, the water treatment system can continuously supply raw water to a user to avoid interruption of water supply. In other words, when the water treatment system of the present invention backflushes the second water treatment apparatus 30, the water treatment system can continuously supply raw water to the user to avoid interruption of water supply.
As shown in fig. 10, 13C and 15C of the drawings, when the water treatment system according to the first preferred embodiment of the present invention is in the third operating state, the sixth communication passage 1006 formed by the planar valve 10 is respectively communicated with the second opening 1102 and the sixth opening 1106 (or the inner chamber 110) of the valve body 11, the seventh communication passage 1007 is respectively communicated with the first opening 1101 and the seventh opening 1107 of the valve body 11, so that raw water is allowed to flow from the sixth opening 1106 of the valve body 11 into the inner chamber 110 of the valve body 11, then flows into the second opening 1102 of the valve body 11 through the sixth communication passage 1006 formed by the planar valve 10, then flows into the first water treatment device 20 through the second communication opening 202 of the first water treatment device 20, and after the first water treatment device 20 is backwashed, the obtained sewage or wastewater flows out of the first communication opening 201 of the first water treatment device 20, then flows into the seventh communication passage 1101 of the planar valve 10 of the valve body 11, and then flows out of the seventh communication passage 1007 of the valve body 11. In other words, the water treatment system of the present invention can control the back flushing of the first water treatment device 20 when the water treatment system is in the third operating state. Accordingly, in the third operating state of the water treatment system, the planar valve 10 of the water treatment system controls water flow to back flush the first filter element 21 of the first water treatment device 20, and thus the third operating state of the water treatment system corresponds to a first filter element backwash operating state of the water treatment system.

The direction of the arrow in fig. 13C indicates the direction of water flow.
Preferably, the twelfth communication passage 10012 formed by the plane valve 10 communicates with the fifth opening 1105 and the sixth opening 1106 (or the inner chamber 110) of the valve body 11, respectively, thereby allowing raw water to flow from the sixth opening 1106 of the valve body 11 into the inner chamber 110 of the valve body 11, and then the twelfth communication passage 10012 formed by the plane valve 10 flows out through the fifth opening 1105 of the valve body 11 and supplies raw water to a user. That is, when the water treatment system is in the third operating state, the water treatment system can continuously supply raw water to a user to avoid interruption of water supply.

In other words, the water treatment system of the present invention can control the forward flushing of the second water treatment device 30 when the water treatment system is in the fourth operating state. Accordingly, in the fourth operating state of the water treatment system, the plane valve 10 of the water treatment system controls water flow to forward flush the second filter element 31 of the second water treatment device 30, and thus, the fourth operating state of the water treatment system corresponds to a second filter element forward-flushing operating state of the water treatment system. Thus, when the water treatment system is in the fourth operating state, the sixth opening 1106 (or the inner chamber 110) of the valve body 11, the third opening 1103 of the valve body 11, the first conductive opening 301 of the second water treatment device 30, the second conductive opening 302 of the second water treatment device 30, the fourth opening 1104 of the valve body 11 and the seventh opening 1107 of the valve body 11 are sequentially conductive, thereby forming a water flow path so that raw water can flow through the second water treatment device 30 and the second water treatment device 30 is being rinsed by raw water, and the resulting sewage or wastewater flows out of the seventh opening 1107 of the valve body 11.

Preferably, the twelfth communication passage 10012 formed by the plane valve 10 communicates with the fifth opening 1105 and the sixth opening 1106 (or the inner chamber 110) of the valve body 11, respectively, thereby allowing raw water to flow from the sixth opening 1106 of the valve body 11 into the inner chamber 110 of the valve body 11, and then the twelfth communication passage 10012 formed by the plane valve 10 flows out through the fifth opening 1105 of the valve body 11 and supplies raw water to a user. That is, when the water treatment system is in the fourth operating state, the water treatment system can continuously supply raw water to a user to avoid interruption of water supply. In other words, when the water treatment system of the present invention is used for forward flushing the second water treatment device 30, the water treatment system can continuously supply raw water to the user so as to avoid interruption of water supply.

In other words, the water treatment system of the present invention can control the forward flushing of the first water treatment device 20 when the water treatment system is in the fifth operating state. Accordingly, in the fifth operating state of the water treatment system, the plane valve 10 of the water treatment system controls water flow to forward flush the first filter element 21 of the first water treatment device 20, and thus the fifth operating state of the water treatment system corresponds to the first filter element forward-flushing operating state of the water treatment system. Therefore, when the water treatment system is in the fifth operating state, the sixth opening 1106 (or the inner chamber 110) of the valve body 11, the first opening 1101 of the valve body 11, the first communication opening 201 of the first water treatment device 20, the second communication opening 202 of the first water treatment device 20, the second opening 1102 of the valve body 11 and the seventh opening 1107 of the valve body 11 are sequentially conducted, thereby forming a water flow path so that raw water can flow through the first water treatment device 20 and the first water treatment device 20 is being rinsed by raw water, and the resulting sewage or wastewater flows out of the seventh opening 1107 of the valve body 11.

That is, when the water treatment system is in the fifth operating state, the water treatment system can continuously supply raw water to a user to avoid interruption of water supply. In other words, when the water treatment system of the present invention is used for forward flushing the first water treatment device 20, the water treatment system can still continuously supply raw water to the user so as to avoid water supply interruption.

In other words, the water treatment system of the present invention can control the back flushing of the second water treatment device 30F when the water treatment system is in the second operating state. Accordingly, in the second operating state of the water treatment system, the planar valve 10F of the water treatment system controls water flow to back flush the second filter element 31F of the second water treatment device 30F, and therefore, the second operating state of the water treatment system corresponds to a second filter element backwash operating state of the water treatment system. Thus, when the water treatment system is in the second operating state, the sixth opening 1106F of the valve body 11F (or the inner chamber 110F of the valve body 11F), the fourth opening 1104F of the valve body 11F, the second through opening 302F of the second water treatment device 30F, the first through opening 301F of the second water treatment device 30F, the third opening 1103F of the valve body 11F and the seventh opening 1107F of the valve body 11F are sequentially communicated, thereby forming a water flow path to enable raw water to flow through the second water treatment device 30F and back-flush the second water treatment device 30F by raw water, and resulting sewage or wastewater flows out of the seventh opening 1107F of the valve body 11F.

In other words, the water treatment system of the present invention can control the back flushing of the first water treatment device 20F when the water treatment system is in the third operating state. Accordingly, in the third operating state of the water treatment system, the planar valve 10F of the water treatment system controls water flow to back flush the first filter element 21F of the first water treatment device 20F, and therefore, the third operating state of the water treatment system corresponds to a first filter element backwash operating state of the water treatment system. Thus, when the water treatment system is in the third operating state, the sixth opening 1106F (or the inner chamber 110F) of the valve body 11F, the second opening 1102F of the valve body 11F, the second communication opening 202F of the first water treatment device 20F, the first communication opening 201F of the first water treatment device 20F, the first opening 1101F of the valve body 11F and the seventh opening 1107F of the valve body 11F are sequentially communicated, thereby forming a water flow path to enable raw water to flow through the first water treatment device 20F and back-flush the first water treatment device 20F by raw water, and the resulting sewage or wastewater flows out of the seventh opening 1107F of the valve body 11F.

In other words, the water treatment system of the present invention can control the forward flushing of the second water treatment device 30F when the water treatment system is in the fourth operating state. Accordingly, in the fourth operating state of the water treatment system, the planar valve 10F of the water treatment system controls water flow to forward flush the second filter element 31F of the second water treatment device 30F, and thus, the fourth operating state of the water treatment system corresponds to the second filter element forward-flushing operating state of the water treatment system. Thus, when the water treatment system is in the fourth operating state, the sixth opening 1106F of the valve body 11F (or the inner chamber 110F of the valve body 11F), the third opening 1103F of the valve body 11F, the first conductive opening 301F of the second water treatment device 30F, the second conductive opening 302F of the second water treatment device 30F, the fourth opening 1104F of the valve body 11F, and the seventh opening 1107F of the valve body 11F are sequentially conductive, thereby forming a water flow path to enable raw water to flow through the second water treatment device 30F and to be rinsed by raw water, and the resulting sewage or wastewater flows out of the seventh opening 1107F of the valve body 11F. The direction of the arrow in fig. 32D indicates the direction of water flow.
Preferably, the twelfth communication passage 10012F formed by the plane valve 10F communicates with the fifth opening 1105F and the sixth opening 1106F (or the inner chamber 110F) of the valve body 11F, respectively, thereby allowing raw water to flow from the sixth opening 1106F of the valve body 11F into the inner chamber 110F of the valve body 11F, and then flows out through the fifth opening 1105F of the valve body 11F through the twelfth communication passage 10012F formed by the plane valve 10F and supplies raw water to a user. That is, when the water treatment system is in the fourth operating state, the water treatment system can continuously supply raw water to a user to avoid interruption of water supply. In other words, when the water treatment system of the present invention is used for forward flushing the second water treatment device 30F, the water treatment system can continuously supply raw water to the user so as to avoid interruption of water supply.
As shown in fig. 31, 32E and 34E of the drawings, when the water treatment system according to the second preferred embodiment of the present invention is in the fifth operating state, the tenth communication passage 10010F formed by the plane valve 10F is respectively communicated with the first opening 1101F and the sixth opening 1106F (or the inner chamber 110F) of the valve body 11F, the eleventh communication passage 10011F formed by the plane valve 10F is respectively communicated with the second opening 1102F and the seventh opening 1107F of the valve body 11F, so that raw water is allowed to flow from the sixth opening 1106F of the valve body 11F into the inner chamber 110F of the valve body 11F, then flows into the first opening 1101F of the valve body 11F through the tenth communication passage 10010F formed by the plane valve 10F, flows into the first water treatment device 20F through the first communication opening 201F of the first water treatment device 20F, and after forward flushing the first water treatment device 20F, the obtained sewage or waste water flows out of the second communication passage 202F from the first communication passage 100F through the second opening 10F of the valve body 11F, and then flows out of the first communication passage 1102F through the second opening 110F of the valve body 11F. In other words, the water treatment system of the present invention can control the forward flushing of the first water treatment device 20F when the water treatment system is in the fifth operating state. Accordingly, in the fifth operating state of the water treatment system, the planar valve 10F of the water treatment system controls water flow to forward flush the first filter element 21F of the first water treatment device 20F, and thus the fifth operating state of the water treatment system corresponds to the first filter element forward-flushing operating state of the water treatment system. Therefore, when the water treatment system is in the fifth operating state, the sixth opening 1106F of the valve body 11F (or the inner chamber 110F of the valve body 11F), the first opening 1101F of the valve body 11F, the first communication opening 201F of the first water treatment device 20F, the second communication opening 202F of the first water treatment device 20F, the second opening 1102F of the valve body 11F and the seventh opening 1107F of the valve body 11F are sequentially conducted, thereby forming a water flow path to enable raw water to flow through the first water treatment device 20F and to be rinsed by raw water, and the resulting sewage or wastewater flows out of the seventh opening 1107F of the valve body 11F.

Preferably, the twelfth communication passage 10012F formed by the plane valve 10F communicates with the fifth opening 1105F and the sixth opening 1106F of the valve body 11F, respectively, thereby allowing raw water to flow from the sixth opening 1106F of the valve body 11F into the inner chamber 110F of the valve body 11F, and then the twelfth communication passage 10012F formed by the plane valve 10F flows out through the fifth opening 1105F of the valve body 11F and supplies raw water to a user. That is, when the water treatment system is in the fifth operating state, the water treatment system can continuously supply raw water to a user to avoid interruption of water supply. In other words, when the water treatment system of the present invention is used for forward flushing the first water treatment device 20F, the water treatment system can still continuously supply raw water to the user so as to avoid interruption of water supply.
