[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] With the advancement of technology, people have developed diverse needs for domestic water. Water treatment equipment can treat the input water, such as adjusting its temperature and quality to meet user requirements, before discharging the treated water to users, greatly facilitating their lives. To make the internal water circuit structure of water treatment equipment simpler and more stable, integrated water circuit boards are now commonly used instead of complex pipework. These boards contain water flow paths, simplifying the equipment structure and improving its structural stability.

[0025] However, since the water flow path is located inside the water circuit board, the processing precision requirements for the water circuit board are very high in order to accurately connect with other structures inside the water treatment equipment, which leads to an increase in the production cost of the water treatment equipment.

[0026] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0027] like Figures 1-6 As shown, Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the water treatment equipment of this application. Figure 2 This is a schematic diagram of the assembly structure of another embodiment of the water treatment equipment of this application. Figure 3 This is a disassembled structural diagram of an embodiment of the water treatment equipment of this application. Figure 4 yes Figure 3 The diagram shows a disassembled structure of the water treatment equipment from another angle. Figure 5 This is a schematic diagram of the disassembled structure of the water circuit board assembly of this application. Figure 6 This is a schematic diagram of the water circuit structure of an embodiment of the water treatment equipment of this application. A specific embodiment of this application provides a water treatment equipment 1, including a tank 2 and a water circuit board assembly.

[0028] The tank body 2 is provided with a medium cavity 21. The water circuit board assembly includes a first plate assembly 4 and a second plate assembly 5, which are assembled and fixed together and are respectively connected to the tank body 2. The water treatment equipment 1 is provided with a heat exchange water inlet 71 and a heat exchange water outlet 74 connecting the medium cavity 21. The heat exchange water inlet 71 is at least partially located within the first plate assembly 4, and the heat exchange water outlet 74 is at least partially located within the second plate assembly 5.

[0029] Water treatment equipment 1 refers to equipment that treats input water to meet user needs, typically used in residential, commercial, or industrial settings. Its water treatment methods may include at least one of filtration, heating, cooling, and softening. Specifically, water treatment equipment 1 can be a water purifier, water heater, water softener, chiller, etc. Tank 2 is a component in the equipment used to store and heat the heat exchange medium. Tank 2 may be equipped with a heating element 62, or the tank 2 may be thermally connected to the heating element 62, thereby heating the heat exchange medium within the medium cavity 21.

[0030] The water circuit board assembly is an integrated plate-like structure that replaces traditional complex water pipe systems. Internally, flow channels are formed through injection molding or machining, while external interfaces are provided for connecting water pipes, valves, sensors, etc. This solution divides the water circuit board assembly into two parts: a first plate assembly 4 and a second plate assembly 5. The first plate assembly 4 is used to input the heat exchange medium into the medium cavity 21 through the heat exchange inlet water passage 71, and the second plate assembly 5 is used to transport the heat exchange medium within the medium cavity 21 through the heat exchange water passage 74 to achieve the heat exchange process.

[0031] Specifically, after the first plate assembly 4 and the second plate assembly 5 are installed, they can be fixed together by means of snap-fit, plug-in, screw-in, etc., to form the entire water circuit plate assembly.

[0032] In the structure provided in this specific embodiment, by splitting the water circuit board assembly into a first board assembly 4 and a second board assembly 5, the internal flow channel structure of each board assembly is relatively simplified. This reduces the complexity and processing precision requirements of the water circuit board assembly while ensuring water circuit functionality, thereby increasing the yield rate of the water circuit board assembly and reducing the production cost of the water treatment equipment 1. Simultaneously, different water circuit modules are set within the first board assembly 4 and the second board assembly 5. When a water circuit module malfunctions, the corresponding board assembly can be disassembled for individual maintenance, making the structure of the water treatment equipment 1 clearer and improving the maintenance efficiency of the water treatment equipment 1.

[0033] See Figures 2-5 In one specific embodiment of this application, the water channel plate assembly covers the top opening of the tank 2 that connects to the medium cavity 21, and the first plate assembly 4 is supported below the second plate assembly 5.

[0034] The top opening refers to the opening made at the top of the tank 2 to connect to the medium cavity 21. The water channels in the water channel plate assembly can be connected to the medium cavity 21 through the top opening.

[0035] In the structure provided in this specific embodiment, the water circuit board assembly is placed over the top opening of the medium cavity 21, which simplifies the structure of the water treatment equipment 1 and makes the structure of the water treatment equipment 1 more compact. During the installation process, the first plate assembly 4 can be placed in place first, then the second plate assembly 5 can be placed on top of the first plate assembly 4, and finally the two can be fixed and locked with the tank body 2. This process is simple and intuitive, which is beneficial to production line operation.

[0036] See Figures 2-5 In one specific embodiment of this application, the second plate assembly 5 includes a second water passage plate 54 and a media pump 51 connected to each other. The first plate assembly 4 is provided with a first mounting position 431, and the media pump 51 is fixed to the first mounting position 431. And / or, the first plate assembly 4 includes a first water passage plate 43 and a waste discharge pump 41 connected to each other, and the second plate assembly 5 is provided with a second mounting position 541, and the waste discharge pump 41 is fixed to the second mounting position 541.

[0037] Among them, the medium pump 51 is a pump used to drive or circulate the heat exchange medium, and the waste discharge pump 41 is a pump used to discharge waste water, heat exchange medium and other substances from the water circuit board assembly.

[0038] In the structure provided in this specific embodiment, the medium pump 51 of the second plate assembly 5 is fixed by the first mounting position 431 on the first water circuit plate 43, and the waste pump 41 of the first plate assembly 4 is fixed by the second mounting position 541 on the second water circuit plate 54. The two larger components, the medium pump 51 and the waste pump 41, which originally required additional space and brackets for installation, are installed in a hidden manner in the mounting positions of the first water circuit plate 43 and the second water circuit plate 54, making the overall structure of the water treatment equipment 1 more compact and contributing to the miniaturization design of the water treatment equipment 1.

[0039] Meanwhile, based on the fixed connection between the first plate assembly 4 and the second plate assembly 5, the first mounting position 431 and the second mounting position 541 can limit, reduce noise, buffer, and dampen the medium pump 51 and the waste pump 41. This can reduce the probability of water leakage caused by pump body vibration, backflow, and unstable connection of the water circuit board. It can also reduce the probability of other components in the water circuit board assembly becoming loose due to the vibration of the medium pump 51 and the waste pump 41, making the sealing performance of the water circuit board assembly more reliable and improving the stability of the water treatment equipment 1.

[0040] like Figures 1-6As shown in a specific embodiment of this application, the water treatment device 1 is further provided with a water supply path 75 that is isolated from and thermally connected to the hot water exchange path 74, and the water supply path 75 is at least partially located within the first plate assembly 4.

[0041] Among them, water supply path 75 refers to the channel through which the water ultimately supplied to users flows within the equipment. The water in this water supply path is directly used for drinking or domestic purposes.

[0042] In the structure provided in this specific embodiment, an indirect heating relationship is established between the water supply path 75 and the heat exchange path 74 through an isolated but thermally conductive design. The heat exchange medium within the heat exchange path 74 can heat the water flowing through the water supply path 75. The bidirectional flow between the two paths enables efficient heat exchange, effectively utilizing the heat of the heat exchange medium to heat a large flow of water. Furthermore, this embodiment explicitly places the isolated water supply path 75 and the heat exchange path 74 into different plate assemblies, reducing the risk of cross-contamination between the two paths and effectively ensuring the water quality emanating from the water supply path 75 and the temperature of the heat exchange medium within the heat exchange path 74.

[0043] See Figures 2-6 In one specific embodiment of this application, the water treatment device 1 further includes a heat exchange component 61, which is connected to the first plate assembly 4. The water supply path 75 includes a water inlet path 751, a heating water path 752, and a water outlet path 753 connected sequentially. The water inlet path 751 and the water outlet path 753 are disposed within the first plate assembly 4. The heating water path 752 is disposed within the heat exchange component 61. A portion of the heat exchange water path 74 is disposed within the heat exchange component 61, and the heating water path 752 is thermally connected to the portion of the heat exchange water path 74 disposed within the heat exchange component 61.

[0044] The heat exchange component 61 is a separate component from the water circuit board assembly, specifically designed for efficient heat transfer between two fluids. Internally, it contains a heating water circuit 752 and a heat exchange water circuit 74 that are very close together but physically isolated. The heating water circuit 752 and the heat exchange water circuit 74 can exchange heat through the large-area heat-conducting walls within the heat exchange component 61. Furthermore, the water flow directions in the heating water circuit 752 and the heat exchange water circuit 74 can be opposite, thereby improving the efficiency and uniformity of the heat exchange process.

[0045] Water inlet path 751 is the starting section of water path 75, responsible for guiding the water to be heated to the heating path 752. Heating path 752 is located inside the heat exchange assembly 61 and is the core section where the water temperature actually changes. The water absorbs heat from the heat exchange path 74 within heating path 752, causing its temperature to rise rapidly. Water outlet path 753 is the ending section of water path 75, used to output water that has reached the predetermined temperature from heating path 752.

[0046] In the structure provided in this specific embodiment, specifically, water input from the outside through the first plate assembly 4 undergoes efficient heat exchange with the heat exchange water path 74 in the heating water path 752 of the heat exchange assembly 61. The heated water is then output through the water outlet path 753 of the first plate assembly 4 to supply the user. Placing the heat-conducting connection between the water path 75 and the heat exchange water path 74 within the heat exchange assembly 61 facilitates efficient and stable heat exchange between the two. Simultaneously, it simplifies the structure of the first plate assembly 4 and the second plate assembly 5, reduces the pressure requirements of the first plate assembly 4 and the second plate assembly 5, and allows the first plate assembly 4 and the second plate assembly 5 to only bear the function of water and heat exchange medium flow, thereby improving the stability of the water treatment equipment 1.

[0047] like Figures 2-6 As shown in a specific embodiment of this application, the heat exchange assembly 61 is connected to the second plate assembly 5. The heat exchange water circuit 74 includes a medium input circuit 741, a heat exchange passage 742, and a medium return circuit 743 connected sequentially. The medium input circuit 741 and the medium return circuit 743 are disposed within the second plate assembly 5. The heat exchange passage 742 is disposed within the heat exchange assembly 61 and is isolated from the heating water circuit 752. The heat exchange passage 742 and the heating water circuit 752 are thermally connected. The ends of the medium input circuit 741 and the medium return circuit 743 away from the heat exchange passage 742 are connected to the medium cavity 21.

[0048] The medium input path 741 originates from the medium cavity 21 and delivers the high-temperature heat exchange medium to the flow channel of the heat exchange component 61. The heat exchange passage 742 is located inside the heat exchange component 61 and is the core section in the heat exchange water path 74 that actually performs the heat exchange task. The high-temperature heat exchange medium flows through this passage, transferring heat to the adjacent heating water path 752. The medium return path 743 returns from the heat exchange component 61, delivering the heat exchange medium, which has cooled down after releasing heat, back to the flow channel of the medium cavity 21.

[0049] In the structure provided in this specific embodiment, the second plate assembly 5 serves as the intermediary for the circulation of the heat exchange medium between the medium cavity 21 and the heat exchange assembly 61. Through the medium input path 741, the heat exchange passage 742, and the medium return path 743, the medium cavity 21 and the heat exchange assembly 61 are connected into a complete closed-loop circuit. The second plate assembly 5 is responsible for driving, distributing, and recovering the heat exchange medium. Its functions are highly integrated and modular, perfectly isolating the hot water exchange path 74 from the water consumption path 75. This makes the functional modules in the water treatment equipment 1 more clearly distinguished and stable, reducing the maintenance cost of the water treatment equipment 1.

[0050] See Figures 3-6 In one specific embodiment of this application, the second plate assembly 5 includes a second water channel plate 54 and a return pipe 52 fixedly connected to the second water channel plate 54. The second water channel plate 54 is provided with a first heat exchange interface 542 connecting the medium return path 743 and the heat exchange passage 742. Part of the medium return path 743 is disposed in the second water channel plate 54. One end of the return pipe 52 away from the second water channel plate 54 extends into the bottom end of the medium cavity 21, and the other part of the medium return path 743 is disposed in the return pipe 52. The first plate assembly 4 is provided with a return sleeve 432, and the return pipe 52 passes through the return sleeve 432.

[0051] The return pipe 52 is an independent pipe specifically designed to guide the cooled heat exchange medium back to the bottom of the medium cavity 21. The first heat exchange interface 542 is a physical opening on the second water channel plate 54, serving as the interface connecting the inner and outer flow channels of the plate. Specifically, a flexible hose can be used to connect the first heat exchange interface 542 to the outlet of the heat exchange passage 742 of the heat exchange assembly 61. The return sleeve 432 is a hollow cylindrical structure fixed to the first plate assembly 4, serving to provide a passage and support for the return pipe 52.

[0052] Within the medium cavity 21, the high-temperature heat exchange medium, due to its lower density, is located at the top, while the low-temperature heat exchange medium, due to its higher density, is located at the bottom. In the structure provided in this specific embodiment, the return pipe 52, fixed by insertion, cooperates with the return sleeve 432, allowing the return pipe 52 to extend directly into the bottom of the medium cavity 21. This returns the low-temperature heat exchange medium after heat exchange to the bottom of the medium cavity 21, preventing impact and mixing with the high-temperature heat exchange medium at the top. This maintains a stable temperature of the heat exchange medium output from the top of the tank 2, ensuring that the medium pump 51 always draws the highest temperature medium from the top of the medium cavity 21, thus guaranteeing the heat exchange efficiency and stability of the water treatment equipment 1.

[0053] Meanwhile, the return sleeve 432 can support the long return pipe 52, thereby reducing the shaking caused by the impact of the heat exchange medium on the return pipe 52, and alleviating the material fatigue problem caused by long-term vibration, thus ensuring the sealing performance of the second plate assembly 5 and the service life of the return pipe 52.

[0054] like Figures 3-5 As shown in a specific embodiment of this application, the second plate assembly 5 further includes a medium input pipe 53, and the second water channel plate 54 is provided with a second heat exchange interface 543 connecting the medium input channel 741 and the heat exchange channel 742. One end of the medium input pipe 53 is connected to the second water channel plate 54, and the other end is connected to the medium cavity 21. Part of the medium input channel 741 is disposed in the medium input pipe 53, and another part of the medium input channel 741 is disposed in the second water channel plate 54. The first plate assembly 4 is provided with an input through hole 433, and the medium input pipe 53 passes through the input through hole 433.

[0055] The medium input pipe 53 is an independent pipe specifically designed to draw high-temperature medium from the top of the medium cavity 21 and transport it to the heat exchange assembly 61. The second heat exchange interface 543 is another physical opening on the second water channel plate 54, used to connect the medium input channel 741 to the heat exchange passage 742 of the heat exchange assembly 61. Specifically, a flexible hose can be used to connect the second heat exchange interface 543 to the inlet of the heat exchange passage 742 of the heat exchange assembly 61. The input through hole 433 is a through hole on the first plate assembly 4, used to provide support and positioning for the medium input pipe 53, thus mitigating any swaying of the medium input pipe 53.

[0056] In the structure provided in this specific embodiment, a heat exchange medium output channel symmetrical to the return pipe 52 is formed by setting the medium input pipe 53. Through the coordinated operation of the medium input pipe 53 and the return pipe 52, a stable and complete heat exchange medium circulation system is formed, which can ensure the heat exchange efficiency of the water treatment equipment 1. At the same time, the input through hole 433 can support the medium input pipe 53, thereby reducing the shaking caused by the impact of the heat exchange medium on the medium input pipe 53, and alleviating the material fatigue problem caused by long-term vibration. This ensures the sealing performance of the second plate assembly 5 and the service life of the medium input pipe 53.

[0057] See Figures 3-5In one specific embodiment of this application, the first plate assembly 4 includes a first water channel plate 43 and a waste discharge pipe 42 fixedly connected to the first water channel plate 43. The first water channel plate 43 is provided with a waste discharge interface 434 and a waste discharge water channel 72 with one end connected to the waste discharge interface 434. One end of the waste discharge pipe 42 is connected to the end of the waste discharge water channel 72 away from the waste discharge interface 434, and the other end extends into the bottom end of the medium cavity 21 to connect the waste discharge water channel 72 and the medium cavity 21. The waste discharge interface 434 is used to discharge waste.

[0058] The waste discharge pump 41 is connected to the wastewater discharge channel 72. The waste discharge pipe 42 is an independent pipe specifically designed to penetrate deep into the bottom of the medium cavity 21 to extract and transport waste liquid, impurities, and sediments. The waste discharge interface 434 is a physical interface located on the first water channel plate 43, through which the wastewater discharge channel 72 discharges the waste pumped by the waste discharge pump 41. The wastewater discharge channel 72 is a flow channel located inside the first water channel plate 43, and is the necessary passage for waste to flow from the waste discharge pipe 42 to the waste discharge interface 434.

[0059] In the structure provided in this specific embodiment, waste deposited at the bottom of the medium cavity 21 can be actively discharged through the wastewater discharge path 72 and the wastewater discharge pipe 42, which can prevent this waste from circulating or accumulating in the medium cavity 21 and the hot water exchange path 74, thus preventing secondary pollution and blockage, thereby improving the stability of the water treatment equipment 1. Furthermore, the wastewater discharge path 72 and the wastewater discharge pipe 42 are isolated from the water supply path 75 and the hot water exchange path 74, thus avoiding cross-contamination.

[0060] like Figures 3-6 As shown in a specific embodiment of this application, the first plate assembly 4 is further provided with a return interface 435 and a return water path 73 connected at one end to the return interface 435. The return interface 435 is used to connect to water-using equipment. The end of the return water path 73 away from the return interface 435 is connected to the wastewater discharge path 72. In the return water path 73, the water flows from the return interface 435 to the wastewater discharge path 72.

[0061] The return port 435 is a water pipe interface located on the first plate assembly 4, specifically designed to connect to external water-using equipment. Its function is to receive residual water flowing back from the external water-using equipment. The return water path 73 is a flow channel inside the first water path plate 43, through which water drawn back from the water-using equipment flows to the wastewater discharge path 72. Water-using equipment refers to the terminal electrical appliance or device connected to the water treatment equipment 1 that ultimately provides water services to the user. For example, water-using equipment may include faucets, water dispensers, coffee machines, ice makers, chillers, etc.

[0062] In the structure provided in this specific embodiment, the water output to the water-using equipment can flow back to the water treatment equipment 1 through the return interface 435. The returned water can flow into the wastewater discharge channel 72 along the return water path 73, and thus be discharged outside the water treatment equipment 1 as wastewater. When the water treatment equipment 1 works in conjunction with other downstream water-using equipment, the wastewater discharge pump 41 can be used to draw back the excess water in the water-using equipment and discharge it into the wastewater discharge channel 72, thereby solving the problem of residual water in the water-using equipment, reducing the probability of bacteria growth and odor in the water-using equipment, and ensuring water hygiene.

[0063] See Figures 1-6 The first water circuit board 43 of this application may also be provided with an exhaust port 436, a water inlet port 437, a water outlet port 438, a cold water port 44, and a hot water port 45. The exhaust port 436 is connected to the medium cavity 21 and is used to release gas to relieve pressure when the gas pressure in the medium cavity 21 is too high. The water inlet port 437 is connected upstream of the heat exchange water inlet 71 and the water inlet 751 and is used to input water from the water source or the pre-treatment water device 1 into the heat exchange water inlet 71 and the water inlet 751. The water outlet port 438 is connected downstream of the heat exchange water inlet 71 and the water outlet 753 and is used to output unheated room temperature water from the heat exchange water inlet 71 and heated water from the water outlet 753 to meet the different water needs of users. The cold water interface 44 is used to connect the water inlet 751 and the heating water circuit 752 in the heat exchange component 61, and the hot water interface 45 is used to connect the heating water circuit 752 in the heat exchange component 61 and the water outlet 753.

[0064] Furthermore, the water treatment equipment 1 may also include a heating element 62, which can be connected to the water outlet 753 to reheat the water that has been heated by the heat exchange component 61, thereby rapidly raising the temperature of the large flow of water to meet the usage requirements. Specifically, the heating element 62 may be a thick film heater.
