Abstract

The invention provides a water treatment system, wherein the water treatment system can control a first water treatment device and a second water treatment device to treat water through a single control valve, and further perform secondary treatment on water after primary treatment, so that the complexity of the water treatment system is obviously reduced compared with that of a traditional multi-stage water treatment system, particularly a purifying-softening water treatment system.

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 and/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 water treatment systems with multiple water treatment functions often require not only water treatment functions, but also other functions, such as back flushing of the filter cartridge, especially the 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.
Disclosure of Invention
The main advantage of the present invention is that it provides a water treatment system having at least two water treatment devices, and which can control the water treatment devices through a single control valve to effect treatment of raw water or water to be treated.
Another advantage of the present invention is that it provides a water treatment system wherein at least one of the water treatment devices of the water treatment system is a (water) purifying device and the other water treatment device is a (water) softening device to effect purifying and softening treatment of raw water or water to be treated separately and/or simultaneously, thereby providing purified (treated) water and soft (treated) water to a user separately and/or simultaneously according to the user's needs. Optionally, both water treatment devices of the water treatment system are purifying devices or are softening devices.
Another advantage of the present invention is that it provides a water treatment system wherein two water treatment devices of the water treatment system form one primary water treatment device (or first water treatment device) and one secondary water treatment device (or second water treatment device), the primary water treatment device of the water treatment system may be any water treatment device, the filter cartridge thereof may be any water treatment filter cartridge such as an ultrafiltration cartridge, an activated carbon filter cartridge, a screen filter, a laminated filter, a softening cartridge, or a softening tank with a softening resin built therein, etc., and the secondary water treatment device of the water treatment system may be any water treatment device, the filter cartridge thereof may be any water treatment cartridge such as an ultrafiltration cartridge, an activated carbon filter cartridge, a screen filter, a laminated filter, a softening cartridge, a softening tank with a softening resin built-in, etc. Accordingly, the filter elements of the primary water treatment device and the secondary water treatment device of the water treatment system may be the same or different. Preferably, the filter element of the primary water treatment device of the water treatment system is a purifying filter element, and the filter element of the secondary water treatment device of the water treatment system is a softening filter element (or a softening tank).
Another advantage of the present invention is that it provides a water treatment system wherein the control valve of the water treatment system is a planar valve, wherein the water treatment device of the water treatment system and the planar valve are in communication through respective waterways to effect control of the water treatment waterways.
Another advantage of the present invention is that it provides a water treatment system wherein the planar valve of the water treatment system is capable of controlling water flow to achieve continuous water supply when the water treatment apparatus is being washed forward or backwashed, thereby avoiding interruption of water supply.
Another advantage of the present invention is that it provides a water treatment system wherein the planar valve of the water treatment system is capable of controlling the forward or reverse washing of individual water treatment devices of the water treatment system.
Another advantage of the present invention is that it provides a water treatment system wherein when the water treatment system is in a first operating state, a waterway is formed connecting a primary water treatment device (or first water treatment device) and a secondary water treatment device (or second water treatment device) in series, and the first water treatment device of the water treatment system is located upstream of the second water treatment device, thereby enabling the second water treatment device to treat, such as further soften, the treated water, such as purified water, from the first water treatment device, thereby obtaining clean softened water. Preferably, the treated water treated by the first water treatment device may be supplied to the user directly through one water path or may flow to and be reprocessed by the second water treatment device through another water path.
Another advantage of the present invention is that it provides a water treatment system wherein the first water treatment device, the second water treatment device and the planar valve of the water treatment system are communicated through respective waterways, thereby achieving control of the waterways and treatment of water. In particular, the treated water treated by the first water treatment device flows to two different water outlets, respectively, to provide different treated water, such as purified water and softened water, separately or simultaneously.
Another advantage of the present invention is that it provides a water treatment system in which a planar valve of the water treatment system is capable of simultaneously controlling water flow in a first water treatment device-related waterway and water flow in a second water treatment device-related waterway to flow in different directions without interfering with each other to control the first water treatment device and the second water treatment device of the water treatment system to individually and/or simultaneously effect water treatment and re-treatment of raw water or water to be treated, thereby individually and/or simultaneously providing different treated water, such as purified water and softened water, to a user according to user's needs. In other words, the planar valve of the water treatment system enables the water treatment system of the present invention to simultaneously achieve control of the first water treatment device-related waterway and the second water treatment device-related waterway through a single planar valve.
Another advantage of the present invention is that it provides a water treatment system suitable for pretreatment and reprocessing of raw water, wherein the water treatment system does not require precise components and complex structures, and is simple in manufacturing process and low in cost.

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 1106B of the valve body 11B (or the inner chamber 110B of the valve body 11B), the first opening 1101B of the valve body 11B, the first communication opening 201B of the first water treatment device 20B, the second communication opening 202B of the first water treatment device 20B, the second opening 1102B of the valve body 11B, the third opening 1103B of the valve body 11B, the first conductive opening 301B of the second water treatment device 30B, the second conductive opening 302B of the second water treatment device 30B, the fourth opening 1104B of the valve body 11B, and the fifth opening 1105B of the valve body 11B are sequentially communicated, thereby forming a water flow path connecting the first water treatment device 20B and the second water treatment device 30B in series, so that raw water can flow from the first water treatment device 20B to the second water treatment device 30B and be sequentially treated by the first water treatment device 20B and the second water treatment device 30B.

Accordingly, in the second operating state of the water treatment system, the planar valve 10B of the water treatment system controls water flow to back flush the second filter element 31B of the second water treatment device 30B, 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 1106B of the valve body 11B (or the inner chamber 110B of the valve body 11B), the fourth opening 1104B of the valve body 11B, the second through opening 302B of the second water treatment device 30B, the first through opening 301B of the second water treatment device 30B, the third opening 1103B of the valve body 11B and the eighth opening 1108B of the valve body 11B are sequentially communicated, thereby forming a water flow path to enable raw water to flow through the second water treatment device 30B and back-flush the second water treatment device 30B by raw water, and resulting sewage or wastewater flows out of the eighth opening 1108B of the valve body 11B.

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 30B, the water treatment system can continuously supply raw water to the user to avoid interruption of water supply.
As shown in fig. 29, 32C and 34C of the drawings, when the water treatment system according to the second preferred embodiment of the present invention is in the third operating state, the seventh communication passage 1007B formed by the plane valve 10B is respectively communicated with the second opening 1102B and the sixth opening 1106B (or the inner chamber 110B) of the valve body 11B, the eighth communication passage 1008B is respectively communicated with the first opening 1101B and the eighth opening 1108B of the valve body 11B, so as to allow raw water to flow from the sixth opening 1106B of the valve body 11B into the inner chamber 110B of the valve body 11B, then flows into the second opening 1102B of the valve body 11B through the seventh communication passage 1007B formed by the plane valve 10B, then flows into the first water treatment device 20B through the second communication opening 202B of the first water treatment device 20B, and after back flushing the first water treatment device 20B, the obtained sewage or waste water flows from the first communication passage 1106B of the first water treatment device 20B into the first opening 1101B, then flows out of the first communication passage 1008B through the first opening 10B, then flows out of the valve body 10B, and then flows into the eighth communication passage 1108B through the first opening 10B. In other words, the water treatment system of the present invention can control the back flushing of the first water treatment device 20B 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 10B of the water treatment system controls water flow to back flush the first filter element 21B of the first water treatment device 20B, and therefore, the third operating state of the water treatment system corresponds to the first filter element backwash operating state of the water treatment system.

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, when the water treatment system of the present invention backflushes the first water treatment apparatus 20B, the water treatment system can continuously supply raw water to the user to avoid interruption of water supply.
