Technical Field

The invention relates to the technical field of water treatment, in particular to a waterway controller which can realize synchronous control of raw water supply and water supply after different treatments of a water treatment system, especially the water treatment system. Further, when the water path controller of the water treatment system is in a conducting state, the raw water supply water path of the water treatment system and each treated water path can be kept communicated, and when the water path controller is in a bypass state, an additional raw water (or water to be treated) water path can be formed while the raw water supply water path of the water treatment system and each treated water path are disconnected, so that the continuous water supply of the water treatment system is ensured.

Background

With the increasing health concerns and concerns about water pollution, 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.

To obtain water that is sufficiently clean or meets certain requirements, such as more potable water and/or softened water having a lower hardness, existing water treatment systems often have more than one filter element. For example, many households may install a prefilter upstream of the ultrafiltration water purifier to filter out larger impurities, or an activated carbon filter downstream of the ultrafiltration water purifier to improve the taste of the purified water. Or, a pre-filter is arranged at the upstream of the water softener for softening the water to remove larger impurities, and a purification filter element is further arranged to purify the water before the water is softened. However, such a water treatment machine or a water treatment system having a complex water treatment function or a multi-stage water treatment function, such as an activated carbon-ultrafiltration filtration complex water purification system, an ultrafiltration-RO membrane complex water purification system, a PP cotton-activated carbon complex water purification system, etc., often has a complex water path. For example, a water treatment system capable of providing purified water of different purification degrees, having at least one raw water (or water to be treated) line (or pipe) and two purified water lines, a water treatment system having a combined purification and softening function, having at least one raw water line, one purified water line and/or one soft water line. In order to enable the water treatment system to smoothly realize multifunctional water treatment and simultaneously ensure the stability and the usability of the water treatment system and facilitate maintenance after faults occur, the existing multifunctional water treatment system is mostly provided with a plurality of auxiliary control valves besides a main control valve for controlling water to flow to each valve core so as to respectively control different water paths. However, the auxiliary control valve of the existing water treatment system controls the raw water path and the different water outlet paths as end control. Therefore, when a user performs maintenance of the existing water treatment system, particularly, maintenance of the control valves for controlling the flow of raw water to the respective filter cartridges to control the multistage treatment of water, he or she has to close the auxiliary control valves of all the pipes one by one, which may cause the water supply through the water treatment system to be completely shut off and cause a safety hazard. Particularly in the case of a multi-functional water treatment system in series with the outlet line of a kitchen or the like, the user may have to be faced with the embarrassment of having the water supply completely shut off once the water treatment system fails.

Referring to fig. 1 to 9B of the drawings, a waterway controller according to a first preferred embodiment of the present invention is illustrated, wherein the waterway controller includes a waterway control valve 10 and a set of connection pipes 20, wherein the waterway control valve 10 includes a valve body 11 and a valve core 12, the set of connection pipes 20 includes a first connection pipe 21, a second connection pipe 22, a third connection pipe 23, a fourth connection pipe 24, a fifth connection pipe 25 and a sixth connection pipe 26, wherein the first connection pipe 21, the second connection pipe 22, the third connection pipe 23, the fourth connection pipe 24, the fifth connection pipe 25 and the sixth connection pipe 26 are respectively connected to the valve body 11 of the waterway control valve 10. Preferably, the valve body 11 of the waterway control valve 10 has a valve cavity 110, wherein the first connecting pipe 21, the second connecting pipe 22, the third connecting pipe 23, the fourth connecting pipe 24, the fifth connecting pipe 25 and the sixth connecting pipe 26 are respectively communicated with the valve cavity of the valve body 11 of the waterway control valve 10. It can be understood that, as shown in fig. 1 and 2 of the drawings, the second connection pipe 22, the third connection pipe 23 and the fifth connection pipe 25 of the waterway controller according to the first preferred embodiment of the present invention are respectively communicated with the first port 301, the second port 302 and the third port 303 of the exemplary main control valve 30 of the exemplary multifunctional water treatment system of the present invention, the first connection pipe 21 of the waterway controller is communicated with the water inlet (or the raw water inlet) of the multifunctional water treatment system, the fourth connection pipe 24 is communicated with one water outlet of the exemplary multifunctional water treatment system of the present invention, and the sixth connection pipe 26 is communicated with the other water outlet of the exemplary multifunctional water treatment system of the present invention. Therefore, both ends of the first connection pipe 21 of the waterway controller of the present invention are respectively communicated with the valve cavity 110 of the valve body 11 of the waterway control valve 10 and a water inlet (or raw water inlet) of the multifunctional water treatment system, both ends of the fourth connection pipe 24 are respectively communicated with the valve cavity 110 of the valve body 11 of the waterway control valve 10 and a water outlet of the exemplary multifunctional water treatment system of the present invention, and both ends of the sixth connection pipe 26 are respectively communicated with the valve cavity 110 of the valve body 11 of the waterway control valve 10 and another water outlet of the exemplary multifunctional water treatment system of the present invention. Accordingly, the exemplary multi-functional water treatment system of the present invention controls the water to be treated to flow to the first connection port 301 thereof through the first connection pipe 21, and after the water to be treated is treated by the exemplary multi-functional water treatment system of the present invention, two different kinds of treated water can be generated, one kind of treated water flows to the third connection pipe 23 through the second connection port 302 of the main control valve 30 and further flows to one water outlet of the exemplary multi-functional water treatment system of the present invention through the fourth connection pipe 24, and the other kind of treated water flows to the fifth connection pipe 25 through the third connection port 303 of the main control valve 30 and further flows to the other water outlet of the exemplary multi-functional water treatment system of the present invention through the sixth connection pipe 26. Therefore, one end of each of the first connecting tube 21, the second connecting tube 22, the third connecting tube 23, the fourth connecting tube 24, the fifth connecting tube 25 and the sixth connecting tube 26 is disposed to be respectively communicated with the valve chamber 110 of the valve body 11. In other words, an end of the first connection pipe 21, an end of the second connection pipe 22, an end of the third connection pipe 23, an end of the fourth connection pipe 24, an end of the fifth connection pipe 25, and an end of the sixth connection pipe 26 are disposed to communicate with the valve chamber 110 of the valve body 11, respectively.

As shown in fig. 1 to 10B of the drawings, the valve body 12 of the waterway control valve 10 of the waterway controller according to the first preferred embodiment of the present invention is movably disposed in the valve cavity 110 of the valve body 11, so that the waterway control valve 10 has a first operation state and a second operation state, wherein when the waterway control valve 10 is in the first operation state, the valve body 11 and the valve body 12 of the waterway control valve 10 form a first communication passage 101 respectively communicating with the first connection pipe 21 and the second connection pipe 22, a second communication passage 102 respectively communicating with the third connection pipe 23 and the fourth connection pipe 24, and a third communication passage 103 respectively communicating with the fifth connection pipe 25 and the sixth connection pipe 26, and when the waterway control valve 10 is in the second operation state, the valve body 11 and the valve body 12 of the waterway control valve 10 form a third communication passage 103 respectively communicating with the first connection pipe 21 and the fourth connection pipe 24 And a fourth communication passage 104. It can be understood that the waterway controller of the present invention can realize the synchronous control of the raw water supply and the differently treated water supply of the water treatment system, especially the multifunctional water treatment system. For example, illustratively, according to the first preferred embodiment of the present invention, when the waterway control valve 10 is in the first operation state, the first connection pipe 21, the first communication passage 101 and the second connection pipe 22 form a raw water waterway for supplying water to be treated (or raw water) to a water treatment device, such as a filter element, of a water treatment system; the third connection pipe 23, the second communication passage 102 and the fourth connection pipe 24 form a water supply path for treated water to flow out; the fifth connection pipe 25, the third communication passage 103 and the sixth connection pipe 26 form another water supply path for treated water to flow out. Further, when the waterway control valve 10 is in the second operating state, the valve core 12 of the waterway control valve 10 is moved relative to the valve body 11, the valve body 11 and the valve core 12 of the waterway control valve 10 no longer form the first communication channel 101, the second communication channel 102 and the third communication channel 103, the waterway control valve 10 controls to suspend the supply of raw water to a water treatment device (or a filter element) of a water treatment system, and the water treatment system suspends the treatment of water to be treated and the supply of treated water. In addition, the first connection pipe 21, the fourth communication passage 104 and the fourth connection pipe 24 further form an additional water path for water to be treated, to ensure that water is continuously supplied through the water treatment system. In other words, the waterway controller of the present invention can ensure that water (treated water or water to be treated) is supplied through the water treatment system (or the waterway controller) regardless of whether the water treatment system is in the water treatment operation state (first operation state) or in the standby state (second operation state). In other words, when the water treatment system is switched to treat the water to be treated, the waterway controller can ensure the formation and the conduction of the water waterway to be treated and each treated water waterway; when the water treatment system is switched to stop the water to be treated from being treated, the waterway controller of the invention cuts off the waterway of the water to be treated and the waterways of the treated water at the same time, and forms a water supply waterway of the water to be treated. The continuous water supply function of the water path controller is very important under many conditions. For example, in the event of damage to a filter element of a water treatment system, water supply to a water-using site is ensured. Therefore, the water path controller further improves the fire safety of water using places.

As shown in fig. 3 to 6 of the drawings, when the waterway control valve 10 of the waterway controller according to the first preferred embodiment of the present invention is in the second operating state, the valve body 11 and the valve core 12 further form a fifth communication channel 105 respectively communicated with the first connection pipe 21 and the sixth connection pipe 26. However, it is considered that the valve body 11 and the valve core 12 may not form the fourth communication passage 104 communicating with the first connection pipe 21 and the fourth connection pipe 24, respectively, when the waterway control valve 10 is in the second operation state. In this case, the fifth communication passage 105 communicating with the first connection pipe 21 and the sixth connection pipe 26 may be named a fourth communication passage. As described herein below, the first, second, third, fourth and fifth and/or sixth are used herein only to name and distinguish between different components (or elements) of the invention, which do not have an ordinal or numerical meaning per se.

As shown in fig. 11 to 17B of the drawings, the valve body 11A of the waterway control valve 10A of the waterway controller according to the second preferred embodiment of the present invention has a valve chamber 110A, wherein the valve core 12A of the waterway control valve 10A is movably disposed in the valve chamber 110A of the valve body 11A, such that the waterway control valve 10A has a first operation state and a second operation state, wherein when the waterway control valve 10A is in the first operation state, the valve body 11A and the valve core 12A of the waterway control valve 10A form a first communication passage 101A respectively communicating with the first connection pipe 21 and the second connection pipe 22, a second communication passage 102A respectively communicating with the third connection pipe 23 and the fourth connection pipe 24, and a third communication passage 103A respectively communicating with the fifth connection pipe 25 and the sixth connection pipe 26, when the waterway control valve 10A is in the second operating state, the valve body 11A and the valve core 12A of the waterway control valve 10A form a fourth communicating channel 104A respectively communicating with the first connecting pipe 21 and the fourth connecting pipe 24. It can be understood that the waterway controller of the present invention can realize the synchronous control of the raw water supply and the differently treated water supply of the water treatment system, especially the multifunctional water treatment system. For example, exemplarily, according to the second preferred embodiment of the present invention, when the waterway control valve 10A is in the first operation state, the first connection pipe 21, the first communication channel 101A and the second connection pipe 22 form a raw water waterway for supplying water to be treated (or raw water) to a water treatment device of a water treatment system, such as a filter element; the third connection pipe 23, the second communication passage 102A and the fourth connection pipe 24 form a water supply path for treated water to flow out; the fifth connection pipe 25, the third communication passage 103A and the sixth connection pipe 26 form another water supply path for treated water to flow out. Further, when the waterway control valve 10A is in the second operating state, the valve element 12A of the waterway control valve 10A is moved relative to the valve body 11A, the valve body 11A and the valve element 12A of the waterway control valve 10A no longer form the first communication channel 101A, the second communication channel 102A and the third communication channel 103A, the waterway control valve 10A controls to suspend the supply of raw water to the water treatment device (or filter element) of the water treatment system, and the water treatment system suspends the treatment of water to be treated and the supply of treated water.
