Description

Technical Field

[0001] This application relates to the technical field of water treatment equipment, and particularly to a water treatment equipment and a waterway control method for water treatment equipment. Background Art

[0002] Most existing water purification equipment uses air cooling to adjust the water temperature, mainly by using a fan and a heat sink to cool or refrigerate the water tank. However, the air cooling method is easily affected by the ambient temperature. Especially in a high-temperature environment, the air cooling efficiency decreases, resulting in unstable refrigeration effects. In addition, the air cooling structure is usually large in volume, and the heat dissipation effect depends on air circulation, which limits the design flexibility and overall performance improvement of the water purification equipment.

[0003] In view of the above problems, some water purification equipment in the prior art has introduced a waterway heat exchange design, but mostly uses a single heat exchange path and lacks the ability to flexibly switch different heat exchange requirements, resulting in limited heat exchange efficiency and unable to balance the optimization of rapid refrigeration and heating effects. At the same time, there are deficiencies in flow control for a single heat exchange structure, which affects the water flow rate and heat exchange efficiency of the waterway and cannot achieve efficient water temperature adjustment and effective waterway sterilization.

Detailed implementation manners

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0023] Existing water purification devices mostly use the air-cooling method for water temperature adjustment, mainly cooling or refrigerating the water tank through a fan and heat sink. However, the air-cooling method is easily affected by the ambient temperature. Especially in a high-temperature environment, the air-cooling efficiency decreases, resulting in unstable refrigeration effects. In addition, the air-cooling structure is usually large in volume, and the heat dissipation effect depends on air circulation, which limits the design flexibility and overall performance improvement of the water purification device.

[0024] In response to the above problems, some water purification devices in the prior art have introduced a water path heat exchange design, but mostly use a single heat exchange path and lack the flexibility to switch between different heat exchange requirements, resulting in limited heat exchange efficiency and being unable to balance the optimization of rapid refrigeration and heating effects. At the same time, there are deficiencies in flow control in a single heat exchange structure, affecting the water flow rate and heat exchange efficiency of the water path and being unable to achieve efficient water temperature adjustment and effective water path sterilization.

[0025] In addition, the connection method of the existing heat exchange device is relatively complex, and the liquid path control is not fine enough, making it difficult to achieve efficient switching of the heat exchange water path, which limits the overall performance improvement of the temperature control device. The optimization of flow rate and heat exchange is insufficient, resulting in the refrigeration and heating effects being difficult to reach the ideal level, affecting the ice-making speed and sterilization effect of the water purification equipment. There is an urgent need for a new water path structure and liquid path control technology that can flexibly regulate the heat exchange path and improve the heat exchange efficiency.

[0026] Based on this, referring to Figures 1 to 5 As shown, an embodiment of the present invention provides a water treatment device 10, which includes a water path structure 100, a filter element assembly 200, a temperature control device 400, a heat exchange water path, and a liquid path control device; the water path structure 100 is provided with a water inlet 110, a waste water outlet 120, and a water outlet; the filter element assembly 200 is provided with a water inlet end 211, a purified water end 213, and a waste water end 212, the waste water end 212 is connected to the waste water outlet 120, and the purified water end 213 is connected to the water outlet; the temperature control device 400 includes a heat exchange element 410 and a heat exchange assembly 420, the heat dissipation end of the heat exchange element 410 is thermally coupled to the heat exchange assembly 420, and the heat exchange element 410 is communicated with the heat exchange assembly 420 to form a circulation loop; wherein, the heat exchange element 410 includes a plurality of heat exchange channels, and the plurality of heat exchange channels include at least one of a first heat exchange channel 401, a second heat exchange channel 402, and a third heat exchange channel 403; the first heat exchange channel 401 is respectively connected to the waste water end 212 and the waste water outlet 120; the input end of the second heat exchange channel 402 is connected to the purified water end 213, and the output end of the second heat exchange channel 402 is connected to the waste water outlet 120; the input end of the third heat exchange channel 403 is connected to the water inlet 110, and the output end of the third heat exchange channel 403 is respectively connected to the water inlet end 211 and the waste water outlet 120; the liquid path control device is used to control the on-off of the water source in the circulation loop, the first heat exchange channel 401, the second heat exchange channel 402, and the third heat exchange channel 403.

[0027] The water treatment device 10 of this embodiment realizes independent circulation heat exchange of three water sources of waste water, purified water, and inlet water by setting a multi-channel heat exchange element 410 including a first heat exchange channel 401, a second heat exchange channel 402, and a third heat exchange channel 403. Each heat exchange channel does not interfere with each other and can transfer heat efficiently at the same time, significantly improving the heat exchange efficiency of the temperature control device 400.

[0028] Using the water-cooled heat exchange method to replace the traditional air-cooled method overcomes the adverse effects of ambient temperature on the refrigeration effect and ensures the stability and reliability of the refrigeration process. The multi-channel heat exchange structure increases the water flow rate in the water path, improves the heat exchange speed, realizes rapid refrigeration, and shortens the water temperature adjustment time. In addition, by accurately controlling the on-off of each heat exchange channel through the liquid path control device, the water flow distribution is optimized, further improving the heat exchange efficiency and energy-saving effect. This design also makes the overall structure of the water treatment device 10 more compact, improves the flexibility of the device design, and is convenient for integration and maintenance.

[0029] In summary, the temperature control device 400 of the water treatment equipment 10 in this embodiment adopts a multi-channel water-cooled heat exchange structure and liquid path control, achieving a significant improvement in the refrigeration effect, ensuring the stability and efficiency of the refrigeration process, while optimizing the equipment volume and structural layout, and solving the problems of unstable refrigeration efficiency and large volume restricting design flexibility in the air-cooled method.

[0030] In one embodiment, the liquid path control device includes a switching valve, which is respectively connected to the first heat exchange channel 401, the second heat exchange channel 402, and the third heat exchange channel 403, and is used to control the on / off of each heat exchange channel. Specifically, the switching valve can be a multi-way switching valve or a multi-position multi-way valve, which can realize the centralized control and switching of multiple heat exchange channels. The advantage of using a switching valve as the liquid path control device is that the structure is relatively simple, the control is centralized, it is convenient for system integration and maintenance, the switching response speed is fast, it can meet the flexible switching requirements of different heat exchange paths, improve the heat exchange efficiency of the system and the stability of water temperature adjustment. At the same time, by reasonably designing the channel structure and sealing performance of the switching valve, the water flow crosstalk between the heat exchange water paths can be effectively avoided, ensuring the independence and accuracy of the heat exchange process.

[0031] In another embodiment, the liquid path control device includes a plurality of solenoid valves, which are respectively arranged at key positions of the first heat exchange channel 401, the second heat exchange channel 402, and the third heat exchange channel 403. Each solenoid valve independently controls the on / off of the corresponding heat exchange channel, realizing the refined distribution and adjustment of the water flow. The liquid path control device using a plurality of solenoid valves has the advantages of flexible control, rapid response, and can realize automatic control and remote monitoring. By respectively controlling the opening or closing of the solenoid valves on each heat exchange channel, the system can dynamically adjust the flow rate and heat exchange state of each channel according to actual needs, realizing a multi-mode heat exchange strategy. This method enhances the intelligent level of the water treatment equipment, improves the user experience and energy-saving effect. In addition, the independent solenoid valve configuration helps the system to quickly isolate the faulty channel when a single channel fails, ensuring the normal operation of other channels, and improving the reliability and maintenance convenience of the equipment.

[0032] It should be noted that the selection of the two liquid path control devices, the switching valve and the plurality of solenoid valves, can be comprehensively determined according to the scale, structural complexity, cost budget, and control accuracy requirements of the water treatment equipment. In small or medium-sized equipment, using a single switching valve can simplify the system structure and reduce costs; while in large-scale equipment or equipment with high requirements for heat exchange control, using a plurality of solenoid valves can provide more detailed and flexible control strategies to adapt to complex and changeable operating conditions. Both control methods can effectively manage the water flow in the first heat exchange channel 401, the second heat exchange channel 402, and the third heat exchange channel 403, ensuring the heat exchange efficiency and the stability of water temperature adjustment.

[0033] In one embodiment, the water treatment device 10 further includes a water storage tank 300. The water storage tank 300 is connected to the purified water end 213, and the cold end of the heat exchange member 410 is thermally coupled to the water storage tank 300.

[0034] Specifically, the water outlet includes a purified water outlet 130 and a cold water outlet 140. The purified water outlet 130 is connected to the filter element assembly 200 and is used to output filtered water. The cold water outlet 140 is connected to the water storage tank 300 and is used to output cold water.

[0035] Furthermore, to achieve a better heat exchange effect, the heat exchange member 410 can be made of a high thermal conductivity material, such as copper or aluminum alloy. Copper is preferably used because of its excellent thermal conductivity, which can accelerate the heat transfer speed and thus improve the response speed of water temperature regulation. When the cold end of the heat exchange member 410 is thermally coupled to the water storage tank 300, clamping, welding or placing the cold end of the heat exchange member 410 in the water storage tank 300 can be adopted to ensure good thermal contact, reduce thermal resistance and improve heat exchange efficiency. At the same time, the structure of the heat exchange member 410 can be designed as a multi-channel flow path structure. Specifically, the water inlet 110 and the wastewater outlet 120 in the water path structure 100 are connected to the heat exchange member 410 through multiple branches, thereby forming multiple parallel heat exchange channels. This multi-channel design can increase the contact area between water and the heat exchange member 410, improve the heat exchange rate, and the uniform distribution of flow rate is beneficial to reducing local overheating or overcooling phenomena.

[0036] Specifically, the connection method between the heat exchange member 410 and the heat exchange assembly 420 can adopt a quick connector or a modular connection structure, which is convenient for disassembly and maintenance, and improves the maintainability and service life of the equipment.

[0037] The number of the water inlet 110 and the wastewater outlet 120 in the water path structure 100 can be adjusted according to the design requirements of the water treatment device 10. Specifically, the number of the water inlet 110 and the wastewater outlet 120 can be one, two or more than two, and no unique limitation is made here. Setting multiple water inlets 110 or wastewater outlets 120 can achieve segmented heat exchange or multi-path parallel heat exchange, further improving the adjustment flexibility of water flow and heat exchange efficiency, and meeting the diverse needs under different usage environments.

[0038] It should be noted that the water flow rate has a great influence on the heat exchange efficiency. When the liquid path control device adjusts the water flow rate, the flow rate can be set to multiple gears, which is specifically determined according to the actual design requirements. When the flow rate is too low, the heat exchange is insufficient, resulting in a decrease in refrigeration or heating efficiency; while when the flow rate is too high, although the heat exchange speed increases, it may increase the system energy consumption and the pump load, reducing the overall energy efficiency ratio. Therefore, reasonably controlling the flow rate is of great significance for achieving efficient and energy-saving water temperature regulation.

[0039] In some embodiments, the water treatment device 10 further includes a housing structure 600. As an installation carrier, the housing structure 600 is used to install the water circuit structure 100, the filter element assembly 200, the water storage tank 300, and the temperature regulating device 400. The housing structure 600 not only provides a stable mechanical support for each functional component but also forms the appearance framework of the overall device, ensuring the reasonable layout and secure fixation of each component.

[0040] Inside the housing structure 600, a middle frame and a cover plate can be provided. The middle frame serves as an internal skeleton and plays a role in carrying and fixing each functional module. The middle frame structure is usually made of metal or high-strength engineering plastics to ensure its structural rigidity and durability. Reserved installation holes and clamping positions are provided inside the middle frame, facilitating the precise positioning and secure installation of components such as the water circuit structure 100, the filter element assembly 200, the water storage tank 300, and the temperature regulating device 400. By reasonably designing the structure of the middle frame, the space waste between components can be effectively reduced, the internal structure of the device can be made more compact, and the overall space utilization rate can be improved.

[0041] The cover plate and the middle frame are detachably connected, which is convenient for the daily maintenance and component replacement of the device. This connection method can adopt screw fixation, snap connection, or magnetic attraction design, and is specifically selected according to the actual use environment and maintenance requirements. The screw fixation method has a stable structure and is suitable for occasions that require frequent disassembly and assembly; the snap connection is simple and fast and is suitable for users to perform self-maintenance; the magnetic attraction connection improves the convenience of disassembly and assembly and the overall aesthetics. Through the detachable cover plate design, users or maintenance personnel can easily open the device for filter element replacement, internal cleaning, or fault troubleshooting, significantly improving the usability and maintenance efficiency of the water treatment device 10.

[0042] In addition, the housing structure 600 can also be equipped with a heat insulation layer or a sealing strip to enhance the heat preservation performance and the waterproof and dustproof capabilities of the device, further improving the stability and service life of the water treatment device 10. The material selection of the housing can also vary according to different application environments. For example, environmentally friendly and durable materials such as ABS plastic and polycarbonate are used, which have good corrosion resistance and mechanical strength and meet the aesthetic requirements of the appearance design at the same time.

[0043] It should be noted that the size and shape design of the housing structure 600 can be optimized according to the volume and layout of the internal components. The size can be compact, medium-sized, or large-sized, and can be specifically customized according to the installation environment and user needs. In the compact design, the housing reduces its volume through modular integration, facilitating installation on a desktop or kitchen countertop; the medium-sized design takes into account both performance and space and is suitable for home and office environments; the large-sized design is suitable for occasions with high requirements for refrigeration capacity and water treatment capacity.

[0044] Specifically, the heat exchange component 410 includes, but is not limited to, a combined structure of a semiconductor refrigeration chip, a compressor, and a heat conduction element. This combined structure is designed to optimize the refrigeration efficiency and heat exchange performance of the water treatment device 10, thereby meeting the water temperature adjustment requirements of different users.

[0045] In one embodiment, as an efficient refrigeration element, the semiconductor refrigeration chip has the advantages of small size, light weight, and no moving parts. Its working principle is based on the Peltier effect, generating a temperature difference in the semiconductor material through the flow of current, thereby achieving heat transfer. In this embodiment, the cold end of the semiconductor refrigeration chip can be in direct contact with the water storage tank 300, so as to quickly and effectively reduce the temperature of the water in the tank. It should be noted that the number of semiconductor refrigeration chips can be one or more, and the specific configuration can be adjusted according to the required refrigeration capacity and space limitations. The parallel configuration of multiple semiconductor refrigeration chips can increase the refrigeration rate and further improve the heat exchange efficiency. The heat dissipation end of the semiconductor refrigeration chip can achieve the heat conduction function through thermal coupling with the heat exchange component 420, and achieve the heat dissipation function through the heat exchange component 420.

[0046] In another embodiment, as the core part of a traditional refrigeration system, the compressor realizes heat transfer by compressing the refrigerant. Its working principle is to compress the low-pressure gas into a high-pressure gas, and achieve heat removal or absorption through the condensation and evaporation processes, so as to achieve more flexible power regulation and higher energy efficiency.

[0047] In some embodiments, the semiconductor refrigeration chip and the compression refrigeration scheme can also be combined. By combining the semiconductor refrigeration chip and the compression refrigeration scheme, the heat exchange component 410 can flexibly switch between refrigeration and heating to meet the diverse water temperature requirements of users. For example, when rapid cooling is required, the system can first enable the semiconductor refrigeration chip for preliminary refrigeration, and then further reduce the water temperature in combination with the operation of the compressor; while when heating is required, the system can change the flow direction of the refrigerant and use the heat of the compressor for heating. This flexible temperature adjustment mechanism significantly improves the functionality of the water treatment device 10.

[0048] The liquid path control device further includes a control module, which is connected to each valve body through a communication line and is responsible for real-time control and management of the opening and closing states of the valve bodies. The control module can not only achieve the function of automatically opening and closing the valves, but also dynamically adjust the valve body state according to the sensor feedback (such as flow sensors, pressure sensors, water quality sensors, etc.) to optimize the operation efficiency and safety of the water path system. For example, when it is detected that the filter element is blocked or the waste water discharge is abnormal, the control module can automatically close the inlet valve 511 or the waste water valve 512 and issue an alarm prompt to ensure the safe operation of the system.

[0049] The specific implementation methods of the control module are diverse, covering various industrial and embedded control units, such as programmable logic controllers (PLCs), STM32 microcontrollers based on the ARM Cortex-M core, general single-chip microcontrollers, field-programmable gate arrays (FPGAs), etc. The selection of different controllers can be reasonably configured according to the complexity of the water treatment device 10, the response speed requirements, and the cost budget. PLCs have powerful industrial control capabilities and stability, and are suitable for large or complex systems; STM32s and single-chip microcontrollers are suitable for embedded applications with small size and low power consumption; FPGAs provide highly flexible parallel processing capabilities and are suitable for occasions with special customization requirements for control logic.

[0050] The control module is usually installed inside the device, can collect the device operation data in real time, execute the preset program, and achieve precise control and status monitoring of the liquid path valve body. This module can also be connected to an external intelligent terminal or cloud platform through a communication interface to support remote management, fault diagnosis, and maintenance, improving the intelligent level and user experience of the water treatment device 10.

[0051] Through the above structural design, the liquid path control device not only realizes the precise regulation of the water inlet, wastewater, purified water, and cold water flow paths, but also improves the flexibility and safety of the system by combining automation control technology. This design effectively avoids human operation errors, shortens the response time, and improves the overall operation stability and reliability of the water treatment device.

[0052] In one embodiment, the liquid path control device further includes a temperature sensor. The temperature sensor is used to monitor the temperature signal in the heat exchange water path in real time and feed back the collected temperature data to the control module. The control module intelligently regulates the water source output by the heat exchange member 410 according to the preset temperature threshold to realize the automatic switching of the water flow path.

[0053] Specifically, when the temperature sensor detects that the water temperature in the heat exchange water path exceeds the set threshold, the control module will instruct the liquid path control device to guide the heat exchange water to the wastewater outlet 120 for waste discharge treatment, avoiding the circulation of high-temperature water bodies in the system, preventing equipment overheating or water quality deterioration, and ensuring the safe and stable operation of the system and water quality hygiene.

[0054] Conversely, when the water temperature does not exceed the preset threshold, the control module controls the heat exchange water to flow along the internal circulation path of the water treatment device 10, realizing the efficient heat exchange and recycling of the water source among the storage tank 300, the heat exchange member 410, and the heat exchange assembly 420. At this time, the water temperature in the water path remains within a reasonable range, which can continuously provide a stable water temperature regulation effect, and at the same time improve energy efficiency and save energy consumption through circulating heat exchange.

[0055] This temperature sensing and intelligent control mechanism ensures that the temperature of the hot water exchange water path is always within a controllable range, avoiding both equipment damage and water quality safety hazards caused by excessive temperature, and achieving efficient and energy-saving water temperature regulation, thereby enhancing the performance stability and usage safety of the water treatment equipment 10. In addition, the control module can also make comprehensive judgments by combining other sensor data (such as flow sensors and water quality sensors), further optimizing the water path control strategy to meet the precise water temperature management requirements under different working conditions. The arrangement position of the temperature sensor can be flexibly set. It can be used to detect the temperature of the hot water source in the heat exchange component 410 or to monitor the temperature signal of the heat exchange assembly 420. The specific design can be adjusted according to actual needs and system structure, and there is no unique limitation. Multi-point temperature acquisition can provide more comprehensive temperature data support for the liquid path control device, further optimizing the liquid path switching strategy and improving the heat exchange efficiency and equipment response speed.

[0056] Referring to Figure 3 As shown in (a) of , in one embodiment, the heat exchange component 410 includes a plurality of heat exchange tubes 411, the plurality of heat exchange tubes 411 are arranged in parallel, and a plurality of heat exchange channels are respectively provided in the plurality of heat exchange tubes 411 one by one.

[0057] In this embodiment, the design scheme of sequentially connecting a plurality of heat exchange tubes 411 in parallel significantly improves the overall heat exchange capacity of the heat exchange component 410. A plurality of heat exchange channels (such as a first heat exchange channel 401, a second heat exchange channel 402, a third heat exchange channel 403, and a fourth heat exchange channel 404) are sequentially provided inside the plurality of heat exchange tubes 411, and each heat exchange channel is sequentially arranged in different heat exchange tubes. This multi-channel layout enhances the heat exchange area and expands the contact area between water and the heat exchange tube wall, thereby improving the heat transfer efficiency.

[0058] Specifically, the parallel arrangement of the plurality of heat exchange tubes 411 reduces the pressure loss of the fluid during the heat exchange process, which is beneficial to ensuring the rapid conduction of heat while maintaining a relatively high flow rate. This design also has good modular characteristics, facilitating manufacturing and maintenance. By providing at least one heat exchange channel in each heat exchange tube, simultaneous multi-channel heat exchange can be achieved, avoiding the problem of reduced heat exchange efficiency caused by too low a flow rate when a single channel is working.

[0059] In terms of structural layout, multiple heat exchange tubes 411 are connected in sequence to form a compact overall structure, which is beneficial for saving space and meeting the compactness requirements of the overall design of the water treatment equipment. This layout method also facilitates reasonable arrangement between the water storage tank 300 and the heat exchange component 420, realizes efficient connection of the circulation loop, reduces the pipeline length and connection points, and reduces the leakage risk and thermal resistance of the system. The fourth heat exchange channel 404 communicates with the heat exchange component 420 to form a circulation loop, which is mainly used to quickly discharge waste heat or introduce cold water to improve the heat exchange efficiency. This structural design facilitates concentrating the heat exchange process in a specific channel, which is convenient for control and adjustment and improves the response speed of the system.

[0060] Specifically, multiple heat exchange tubes 411 can be combined and fixed in various ways, such as by snap connection, welding, bonding, etc. Specifically, the snap connection method has the advantages of simple structure and convenient disassembly and assembly, and is suitable for occasions that require frequent maintenance or replacement; the welding method can achieve a firm combination between the heat exchange tubes, ensuring good mechanical strength and stable thermal contact, and is applicable to applications with high requirements for heat exchange efficiency and long-term reliability; the bonding method can use thermally conductive adhesives, which not only simplifies the process flow, but also effectively fills the tiny gaps between the pipes, reduces the thermal resistance, and improves the heat conduction efficiency.

[0061] When multiple heat exchange tubes 411 are in close contact with each other, in addition to the water flow heat exchange inside each tube, heat can also be directly conducted through the tube walls between the heat exchange tubes to form an additional heat transfer path. This heat conduction function brought by the contact between the heat exchange tubes effectively enhances the heat exchange capacity of the overall heat exchange component 410, realizes the collaborative utilization of thermal energy between multiple channels, and improves the heat exchange rate and energy efficiency ratio. At the same time, the tightly arranged heat exchange tube structure helps to reduce the volume of the equipment, making the overall water treatment equipment more compact and meeting the strict requirements for space occupation of modern household and commercial water treatment equipment.

[0062] In addition, to ensure good thermal contact between the heat exchange tubes, a thermally conductive paste with high thermal conductivity or a thermal pad can be coated on the contact surface of the tube walls to further reduce the thermal resistance. By reasonably selecting the combination method and supplementing with thermally conductive materials, the overall thermal conduction performance of the heat exchange tube group can be maximally exerted, the thermal efficiency of the heat exchange component 410 can be improved, and the stable and efficient operation of the temperature control device 400 and the entire water treatment equipment 10 can be ensured.

[0063] Refer to Figure 3 As shown in (b) of , in another embodiment, the heat exchange component 410 adopts a structural design in which multiple heat exchange sleeves 412 are sleeved in sequence, and the heat exchange channels are formed between two adjacent heat exchange sleeves 412. This design uses the gap between the sleeves as the water flow channel, and through the close cooperation of multiple layers of sleeves, the function of multi-channel heat exchange is realized, thereby improving the heat exchange efficiency and saving space.

[0064] Specifically, a fourth heat exchange channel 404 is provided inside the innermost heat exchange sleeve 412, and a third heat exchange channel 403, a second heat exchange channel 402, and a first heat exchange channel 401 are respectively formed between the heat exchange sleeves 412 sleeved thereon in sequence. Such a multi-channel structure with layered sleeves not only ensures that the heat exchange channels do not interfere with each other, but also makes full use of the volume of the heat exchange member 410, improving the heat exchange area and the heat exchange speed.

[0065] To ensure the overall structural strength and stability of the heat exchange member 410, multiple heat exchange sleeves 412 can be fixed through connection structures such as ribs, preventing the sleeves from displacing or deforming due to fluid pressure or temperature changes during long-term operation, and ensuring the sealing and stability of the heat exchange channels. The rib structure can be a metal sheet, a reinforcing rib, or a welded rib, or can be designed as a spaced support frame. Specifically, it varies according to different manufacturing processes and material selections, and can effectively improve the mechanical strength and durability of the heat exchange member.

[0066] It should be noted that the sequential arrangement of multiple heat exchange channels is not limited to the above structure, and in actual applications, the channel sequence can be flexibly adjusted according to specific heat exchange requirements and water circuit layouts. For example, the first heat exchange channel 401 can be arranged at the innermost or outermost layer, and the second heat exchange channel 402 and the third heat exchange channel 403 can also be swapped accordingly to adapt to different fluid flow directions and heat exchange strategies, so as to achieve the optimal heat exchange effect. This flexible arrangement design enhances the applicability and customization ability of the heat exchange member 410, meeting the diverse needs of different water treatment equipment designs.

[0067] In addition, the heat exchange member 410 is also provided with end caps, and a plurality of spaced-apart openings are respectively formed on the end caps corresponding to the multiple heat exchange channels. Each opening is internally connected to the corresponding heat exchange channel and is also connected to the external water circuit, ensuring the independence and tightness of the water flow in each heat exchange channel. Through the reasonable design of spaced-apart openings, the mixing and cross-contamination of water flows in different channels are avoided, ensuring the efficient and safe operation of multi-channel heat exchange. The end cap material is usually selected as an engineering plastic or a metal material with corrosion resistance and high mechanical strength, ensuring the sealing performance and durability, and at the same time facilitating the quick connection and disassembly and maintenance of the external water circuit system.

[0068] This end cap structure not only serves to seal the heat exchange sleeve, but also facilitates the interface docking between the heat exchange member 410 and the internal water circuit structure 100 and the heat exchange assembly 420 inside the water treatment equipment 10. The opening positions and sizes on the end caps can be optimized according to the overall layout of the equipment to achieve a reasonable distribution of the heat exchange water circuit and a balanced flow rate, improving the overall energy efficiency and fluid dynamic performance of the equipment.

[0069] In summary, the structure of multiple heat exchange sleeves 412 sleeved in sequence, combined with the rib connection and the end cover opening design, not only ensures the mechanical strength and sealing performance of the heat exchange component 410, but also realizes the efficient, independent flow and flexible layout of multi-channel heat exchange, significantly improving the performance and reliability of the temperature control device 400 in the water treatment device 10. This structure also has good modularity and maintenance convenience, meeting the requirements of modern high-efficiency water treatment devices.

[0070] Specifically, the heat exchange assembly 420 includes a heat exchange pipeline, and both ends of the heat exchange pipeline are respectively connected to the input end and the output end of the heat exchange component 410, thus forming a closed circulation loop. This design enables the heat exchange medium in the temperature control device 400 to circulate between the heat exchange component 410 and the heat exchange pipeline, realizing the efficient transfer and dissipation of heat.

[0071] In this circulation loop, the heat exchange medium absorbs or releases heat when passing through the heat exchange component 410, and then flows through the heat exchange pipeline, using the larger surface area of the heat exchange pipeline to effectively dissipate the heat to the external environment or other heat dissipation devices, completing the heat exchange process. The design of the heat exchange pipeline can adopt a serpentine, coiled or multi-channel structure to increase the contact area with air or the cooling medium and improve the heat dissipation efficiency.

[0072] Through the configuration of this circulation loop, the temperature control device 400 can continuously and stably maintain the temperature of the heat exchange medium within the ideal range, avoiding the performance degradation of the heat exchange medium caused by heat accumulation, and ensuring the refrigeration effect and refrigeration speed of the water treatment device 10. In addition, the closed structure of the circulation loop also helps to reduce the leakage risk of the heat exchange medium, improving the safety and reliability of the system.

[0073] To prevent the wastewater from flowing back and polluting the purified water filter element assembly 200, setting a check valve in the liquid path control device is an effective technical means. The input end of the check valve is connected to the filter element assembly 200, and the output end is respectively connected to the wastewater outlet 120 and the heat exchange component 410. Through the setting of this check valve, it can be ensured that the wastewater can only be discharged in one direction, preventing the wastewater output from the heat exchange component 410 from flowing back to the filter element assembly 200, and avoiding the impurities or bacteria carried in the wastewater from entering the filter element in the reverse direction, ensuring the service life of the filter element assembly 200 and the safety and stability of the purified water quality.

[0074] The check valve can generally be in various forms such as a spring-loaded check valve, a ball valve check valve, or a diaphragm check valve. The specific selection can be flexibly determined according to the water pressure, water flow rate, and installation space of the system. The spring-loaded check valve has sensitive response, small size, and simple structure, and is suitable for installation inside water treatment equipment with limited installation space; the ball valve check valve has good sealing performance and strong corrosion resistance, and is suitable for long-term operating environments; the diaphragm check valve can effectively reduce flow resistance and improve water flow efficiency. Specifically, the material of the check valve can be food-grade plastic, stainless steel, or copper alloy to balance durability and safety.

[0075] In another embodiment, to further optimize the wastewater discharge path and prevent backflow pollution, the wastewater outlet 120 is designed to include two parts, a first wastewater outlet and a second wastewater outlet. The filter element assembly 200 is connected to the first wastewater outlet, and the heat exchange element 410 is connected to the second wastewater outlet, forming two independent wastewater water paths. This design enables the wastewater from the filter element assembly 200 and the wastewater from the heat exchange element 410 to be discharged through different paths respectively, avoiding the cross-flow of the two-way wastewater, and thus more effectively preventing the wastewater from flowing back to the filter element assembly 200.

[0076] By separately setting the first wastewater outlet and the second wastewater outlet, the risk of cross-contamination in the water path can be reduced. At the same time, it is convenient to independently adjust and control the flow rate and pressure of the two wastewater lines respectively, improving the overall stability and safety of the system. Specifically, the number of the first wastewater outlet and the second wastewater outlet can be one each, or can be set to two or more according to the design requirements of the water treatment equipment 10 to achieve segmented discharge or parallel discharge of multiple-way wastewater, further improving the wastewater discharge efficiency and the flexibility of water path management.

[0077] In addition, the pipe connection part and the sealing structure of the first wastewater outlet and the second wastewater outlet can adopt quick connectors or snap connections, which are convenient for disassembly and maintenance, ensure reliable sealing of the connection, and avoid wastewater leakage. This design not only improves the maintenance convenience of the equipment but also enhances the safety performance of the overall system.

[0078] In summary, whether it is to achieve unidirectional flow of wastewater by setting a check valve or to achieve independent discharge of the wastewater path by separately setting multiple wastewater outlets, it effectively avoids the pollution of the filter element assembly 200 by wastewater backflow, ensures the water quality safety of the water treatment equipment 10 and the long-term stable use of the filter element, and improves the reliability of equipment use and the user experience.

[0079] Furthermore, the heat exchange assembly 420 includes a circulation pump 421, and the circulation pump 421 is connected to the heat exchange element 410 through a pipeline to form a loop.

[0080] By setting the cooperation of the circulation pump 421 and the heat exchange element 410, the conveying efficiency of the heat exchange medium in the temperature control device 400 can be significantly improved, thereby enhancing the overall heat exchange effect and the response speed of the system.

[0081] In this embodiment, both ends of the heat exchange member 410 can be respectively connected to the circulation pump 421 to form a complete circulation loop, or the circulation pump 421 is arranged in the above heat exchange pipeline to realize the function of driving the heat exchange medium to be transported in the circulation loop. Specifically, when the circulation pump 421 is directly connected to the heat exchange member 410, the flow rate and flow volume of the heat exchange medium can be effectively controlled to ensure the rapid transfer and dissipation of heat during the heat exchange process. In this configuration, the liquid path control device can intelligently adjust the operating state of the pump according to the real-time temperature signal to achieve dynamic control.

[0082] In summary, by introducing the circulation pump 421, the heat exchange assembly 420 not only improves the transportation efficiency of the heat exchange medium, but also enhances the flexibility and adaptability of the system, ensuring that the water treatment device 10 can maintain efficient water temperature regulation performance under various working conditions.

[0083] In one embodiment, the heat exchange assembly 420 further includes a heat exchange water tank 422. The heat exchange water tank 422 is respectively connected to the circulation pump 421 and the heat exchange member 410 to form a complete heat exchange water path. The main purpose of setting the heat exchange water tank 422 is to increase the storage capacity of the heat exchange medium, thereby enhancing the heat exchange capacity and stability of the system.

[0084] Specifically, the heat exchange water tank 422, as a buffer and storage unit of the heat exchange medium, can effectively alleviate the problem of uneven flow of the heat exchange medium in the system. When the temperature regulation device 400 operates, the heat exchange water tank 422 can store a certain amount of heat exchange medium to ensure that the system can still provide a stable heat exchange effect when the heat exchange load is large or the instantaneous demand changes. In this way, the heat exchange efficiency of the system is significantly improved, and the refrigeration speed becomes more rapid and stable.

[0085] In addition, setting the heat exchange water tank 422 can also realize the recirculation of the heat exchange medium. When the heat exchange medium does not circulate in the heat exchange water path, it can be temporarily stored in the heat exchange water tank 422 to avoid heat loss or accumulation in a certain part of the system. This design not only helps to maintain the stability of the water temperature, but also reduces the frequent replenishment and discharge of the heat exchange medium, improving the operation efficiency and economy of the system.

[0086] In summary, adding the heat exchange water tank 422 not only enhances the storage and recirculation capabilities of the heat exchange medium, but also improves the heat exchange efficiency of the temperature regulation device 400 and the overall stability of the system, effectively meeting the heat management requirements of the water treatment device 10 under high load and variable working conditions.

[0087] In one embodiment, the heat exchange assembly further includes a hot water tank, which is thermally coupled to the heat exchange member 410 and is used to heat the water in the hot water tank. By providing the hot water tank, the water treatment device 10 can not only achieve the refrigeration adjustment of cold water, but also achieve the heating output of hot water, expanding the functionality of the device and meeting the diverse needs of users for cold and hot water.

[0088] Specifically, the hot water in the hot water tank can be directly supplied by the hot water output from the heat exchange hot water tank 422, or can be heated by other heating media transferring heat through the heat exchange member 410. Such a design enables the hot water tank to flexibly receive hot water from different sources, which can not only ensure the temperature stability of the hot water, but also improve the heat exchange efficiency and the energy consumption utilization rate of the system.

[0089] When the hot water in the hot water tank is filtered water, the water treatment device 10 can provide safe and hygienic hot drinking water, meeting the requirements of users for the temperature of drinking water and improving the drinking comfort and user experience. At this time, the hot water is treated by the filter element assembly 200 to ensure that the water quality meets the drinking standard and is heated to the set temperature for convenient daily use.

[0090] On the other hand, when the hot water in the hot water tank is tap water or heat exchange water, it can be used in scenarios with a large demand for hot water in daily life but not for drinking, such as cleaning, cooking, etc. In this case, the device can intelligently switch the hot water source according to user needs or system settings, taking into account both hygiene and safety and usage convenience.

[0091] By integrating the hot water tank, the water treatment device 10 has the function of a cold and hot water integrated machine, significantly improving the comprehensive performance and application range of the device. The cold and hot integrated design not only saves space and installation costs, but also simplifies user operation and enhances the market competitiveness of the device. In addition, the thermal coupling method between the hot water tank and the heat exchange member 410 can be diversified, including but not limited to clamping, welding, embedded structure, etc., to ensure good heat transfer efficiency and reduce heat loss. The material selection of the hot water tank should consider heat resistance, corrosion resistance and hygiene requirements. Commonly used materials include food-grade stainless steel, polypropylene (PP), etc., which not only ensure the use safety but also extend the service life of the device.

[0092] In this embodiment, the filter element assembly 200 is provided with a water inlet end 211, a wastewater end 212 and a purified water end 213. The water inlet end 211 is used to introduce the water source, and the water source is filtered by the filter element assembly 200. The filter element assembly 200 outputs the treated purified water from the purified water end 213, and the wastewater is discharged from the wastewater end 212.

[0093] Specifically, the wastewater end 212 is connected to the heat exchanger 410 and is used to utilize the wastewater discharged from the filter element assembly 200 as a heat exchange medium for heat exchange. By introducing the wastewater into the heat exchanger 410, the waste heat or cold of the wastewater can be effectively recovered and utilized, thereby improving the overall energy efficiency and heat exchange efficiency of the temperature control device 400. This design not only makes full use of the residual heat energy of the wastewater, reduces energy waste, but also reduces the operating cost of the system, which has positive significance for energy conservation and environmental protection.

[0094] The purified water end 213 is connected to the water storage tank 300 and is used to transport the filtered purified water to the water storage tank 300, so that the filtered water can enter the temperature control device 400 for refrigeration and cooling treatment. This structure ensures the water quality safety of the water entering the water storage tank 300 and meets the drinking standard, and at the same time realizes the effective regulation of the water temperature in the water storage tank, improving the user's drinking experience.

[0095] It should be noted that the specific type of filter element installed in the filter element assembly 200 can be selected according to actual application requirements. In this embodiment, the filter element assembly 200 is preferably installed with a reverse osmosis (RO) filter element. The RO filter element can effectively remove dissolved solids, harmful substances and microorganisms in water, ensuring the high purity and safety of the purified water. In addition, in other embodiments, the filter element assembly 200 can also be installed with other types of filter elements, such as activated carbon filter elements, ultrafiltration membrane filter elements, nanofiltration membrane filter elements or composite filter elements, etc. The selection of different filter elements can be adjusted according to the water quality situation, filtration requirements and cost budget to meet the diverse needs of different users.

[0096] Specifically, the number of filter elements in the filter element assembly 200 can be one, two or more. Multiple filter elements can be configured in series or in parallel to achieve a more efficient filtration effect or extend the service life of the filter element. The combination of multiple filter elements not only improves the purification efficiency, but also can perform hierarchical filtration on different pollutants, ensuring the stability and reliability of the filtered water quality. In addition, the connection mode between the wastewater end 212 and the heat exchanger 410 can adopt various forms such as pipeline seal connection, quick connector or threaded connection, etc., to ensure the tightness and safety of the wastewater flowing to the heat exchanger 410, preventing leakage and pollution.

[0097] In one embodiment, the filter element assembly 200 includes a filter element mounting seat 210. The filter element mounting seat 210 is connected to the water circuit structure 100, and the filter element mounting seat 210 is used to mount the external water purification filter element 20.

[0098] This design enables the water purification filter element 20 to be conveniently positioned and disassembled and assembled, greatly improving the replacement efficiency of the filter element and reducing the operation complexity of the user during maintenance.

[0099] The structural design of the filter element mounting seat 210 should take into account the fixing and sealing performance of the filter element. Specifically, the filter element mounting seat 210 can adopt snap - type, threaded or quick - connect type connection methods to ensure the stability and safety of the filter element during use. Among them, the snap - type design facilitates quick disassembly and assembly, while the threaded connection provides better sealing, which is particularly important in high - water - pressure environments. The quick - connect type connection can provide a more convenient operation experience when users need to frequently replace the filter element.

[0100] Specifically, the water inlet end 211, the wastewater end 212 and the purified water end 213 are provided on the filter element mounting seat 210, ensuring the efficient progress of the filtration process within the filter element assembly 200. The wastewater end 212 is responsible for discharging the wastewater after being treated by the filter element, while the purified water end 213 transports the filtered purified water to the water storage tank 300. Through this structural design, the length of the pipeline and the connection points can be effectively reduced, reducing the potential leakage risk in the system and improving the overall safety and reliability.

[0101] In practical applications, the design of the filter element assembly 200 can be flexibly adapted to different types of filter elements to meet diverse water quality treatment requirements. For example, the filter element mounting seat 210 can be compatible with various filter element types such as reverse osmosis (RO) filter elements, activated carbon filter elements, ultrafiltration membrane filter elements, etc., and users can freely choose the appropriate filter element type according to the specific water source situation and purification requirements.

[0102] Furthermore, the filter element assembly 200 also includes a filter element booster pump 220, and the filter element booster pump 220 is connected in the water pipeline between the water circuit structure 100 and the filter element mounting seat 210.

[0103] By setting the filter element booster pump 220, the water delivery efficiency and purification effect of the water source can be significantly improved, especially when the water purification filter element 20 uses a reverse osmosis (RO) filter element.

[0104] The working principle of the filter element booster pump 220 is to increase the flow pressure of the water source to ensure that the water source can pass through the water purification filter element 20 at a higher flow rate, thereby improving the filtration effect. The RO filter element has relatively high requirements for the inlet water pressure, and the filter element booster pump 220 can increase the water source pressure to this range to ensure that the RO filter element can effectively remove dissolved solids and harmful substances in the water, improving the safety and purity of the purified water quality.

[0105] The configuration of the filter element booster pump 220 not only improves the water delivery efficiency of the water source but also extends the service life of the filter element to a certain extent. By maintaining an appropriate filtration pressure, the working environment of the water purification filter element 20 is more stable, thus reducing the damage caused by pressure fluctuations. In addition, the setting of the filter element booster pump 220 can also effectively reduce the residence time of the water source during transportation, reducing the risk of bacterial growth and ensuring the hygienic safety of the purified water.

[0106] Furthermore, the water storage tank 300 includes a refrigeration unit 310 and a cold storage unit 320. The refrigeration unit 310 is connected to the cold storage unit 320, and the refrigeration unit 310 is thermally coupled to the cold end of the heat exchange member 410.

[0107] In this embodiment, the refrigeration unit 310 is used to realize the refrigeration function of water, and can absorb the heat in the water through the refrigeration cycle device, thereby reducing the water temperature; the cold storage unit 320 is used to store the cold water cooled by the refrigeration unit 310, playing the role of cold water buffering and reserve, so that the water storage tank 300 can continuously and stably provide cold water to users.

[0108] Specifically, the thermal coupling between the refrigeration unit 310 and the cold end of the heat exchange member 410 means that the two maintain close thermal conduction contact during the heat exchange process, so that the cold quantity brought by the heat exchange medium in the heat exchange member 410 can be quickly transferred to the water source in the refrigeration unit 310. Through this thermal coupling design, the refrigeration unit 310 can efficiently absorb the low-temperature energy brought by the heat exchange member 410, improve the overall refrigeration efficiency, and shorten the response time of the water temperature reduction.

[0109] As a storage container for cold water, the capacity and structural design of the cold storage unit 320 directly affect the cold storage capacity of the water storage tank 300. The cold storage unit 320 can be insulated with heat-insulating materials to reduce the loss of cold quantity and ensure that the cold water remains at a low temperature for a certain period of time. Specifically, the capacity of the cold storage unit 320 can be set according to the usage requirements of the water treatment device 10, and is specifically selected according to the actual usage environment and user needs to meet the requirements of different cold water supply amounts. Too small a capacity will lead to unstable cold water supply, easy frequent startup of refrigeration, increased energy consumption and equipment wear; too large a capacity will increase the equipment volume and cost, and at the same time may cause too long a residence time of cold water, affecting the freshness of water quality.

[0110] A partition or a heat conduction structure can be provided between the cold storage unit 320 and the refrigeration unit 310, so that the two parts can not only achieve necessary heat exchange, but also be effectively separated to prevent the cold water from being directly disturbed by the refrigeration cycle of the refrigeration unit 310, ensuring the temperature of the cold water in the water storage tank is uniform and stable. In addition, the design of the cold storage unit 320 should also consider being convenient for cleaning and maintenance to ensure the safety and hygiene of the cold water quality. In one embodiment, the cold end of the heat exchange member 410 can be a low-temperature area in contact with the water storage tank 300 to realize the cooling function of the heat exchange member 410.

[0111] In one embodiment, the water storage tank 300 further includes a first cold water pump 330, and the first cold water pump 330 is respectively connected to the refrigeration unit 310 and the cold storage unit 320. By providing the first cold water pump 330, the conveying efficiency of cold water can be significantly improved, ensuring that the circulation of cold water between the refrigeration unit 310 and the cold storage unit 320 is smoother and more stable.

[0112] Specifically, the setting of the first cold water pump 330 can overcome the problem of insufficient flow rate of the water flow in the pipeline caused by factors such as resistance, water pressure difference, and pipeline length, enabling the cold water to be quickly transported from the refrigeration unit 310 to the cold storage unit 320, or from the cold storage unit 320 to the water supply port of the user end. This not only ensures the full utilization of the water resources with a lower temperature in the water storage tank 300, but also effectively avoids the phenomenon of cold water retention and temperature rise, improving the response speed of cold water supply and the user experience.

[0113] In addition, the working mode of the first cold water pump 330 can be continuous operation or designed to be intermittent operation, and it can cooperate with temperature sensors and flow sensors to achieve intelligent control. Through intelligent control, the cold water pump can automatically adjust startup and shutdown according to the water temperature change in the water storage tank and the user's water consumption demand, further improving the energy-saving effect and usability of the system.

[0114] Through the setting of the first cold water pump 330, the water circulation efficiency between the refrigeration unit 310 and the cold storage unit 320 is improved, the temperature distribution of the cold water in the water storage tank 300 is more uniform, reducing the energy waste caused by temperature difference, thereby improving the energy efficiency and stability of the overall refrigeration system. At the same time, the rapidly circulating cold water can better meet the user's requirements for the cold water volume and temperature, improving the operation effect and reliability of the water treatment equipment 10.

[0115] Furthermore, the water storage tank 300 further includes a second cold water pump 340, and the second cold water pump 340 is connected to the cold storage unit 320 and is used to pump out cold water outward. By setting the second cold water pump 340, the output efficiency of cold water can be significantly improved, ensuring that the user end can quickly and stably obtain cold water with the required temperature and flow rate.

[0116] Specifically, the setting of the second cold water pump 340 solves the problems such as insufficient flow rate and unstable pressure that may occur when relying only on gravity or simple pipeline pressure for water supply. Especially when the user's water consumption is large or the pipeline is long with a large water pressure loss, it can effectively ensure the continuity and sufficiency of cold water supply. The second cold water pump 340 increases the transportation pressure and flow rate of cold water from the cold storage unit 320 to the user end, reducing the risk of water supply delay and water temperature rise, and improving the user's drinking experience.

[0117] In addition, the working mode of the second cold water pump 340 can also be designed for intelligent control. For example, by cooperating with flow sensors, pressure sensors, and temperature sensors, it can achieve automatic startup and shutdown according to the user's actual water consumption demand, effectively reducing energy consumption and extending the service life of the pump. Intelligent control can also avoid long-term idling or frequent startups, reducing mechanical wear and failure rate.

[0118] The material selection of the second chilled water pump 340 is also very important. The pump body and the internal fluid contact components are preferably made of corrosion-resistant materials that meet the drinking water hygiene standards, such as food-grade stainless steel, food-grade engineering plastics, etc., to ensure water quality safety and the durability of the equipment. The sealing structure should adopt a reliable mechanical seal or magnetic seal design to prevent leakage and pollution and ensure the safe and stable operation of the system.

[0119] By setting the second chilled water pump 340, the water storage tank 300 can more effectively transport the chilled water to the user end, which not only improves the output efficiency of the chilled water but also optimizes the water supply performance and user experience of the entire water treatment equipment 10. This design ensures sufficient chilled water supply pressure and stable water output, while reducing the phenomenon of chilled water retention in the refrigeration section 310 and the chilled water storage section 320 due to insufficient water pressure, further improving the refrigeration efficiency and energy-saving effect of the system.

[0120] Specifically refer to Figure 2 In the illustrated embodiment, the liquid path control device is provided with a plurality of valve bodies, which respectively include an inlet valve 511, a wastewater valve 512, a purified water valve 513, and a chilled water valve 514. These valve bodies are all arranged on the corresponding water pipelines, corresponding to the water inlet pipeline of the water inlet 110, the wastewater pipeline of the wastewater outlet 120, the purified water pipeline of the purified water end 213 of the filter element assembly 200, and the chilled water pipeline of the chilled water outlet 140 respectively. The setting of the valve bodies can realize the opening and closing control of different water flows in the water path system, ensuring that the fluid path of the system can be effectively managed and meeting the water use requirements of different operation stages of the water treatment equipment 10.

[0121] Specifically, the inlet valve 511 is used to control the entry of the external water source. When the water treatment equipment 10 is started, the control module can open the inlet valve 511 to allow water to enter the filter element assembly 200 for purification treatment; the wastewater valve 512 is used to control the discharge of wastewater, and in cooperation with the filtration process of the purification filter element 20, effectively discharges the wastewater generated by the filter element to avoid the backflow or leakage of wastewater. The purified water valve 513 is arranged on the pipeline of the purified water outlet 130 to control the output of the purified water from the filter element assembly 200 to the user end, ensuring the stability and accuracy of the purified water flow; the chilled water valve 514 is arranged on the pipeline of the chilled water outlet 140 to control the flow of the chilled water output from the water storage tank 300 to the user end to meet the immediate demand of the user for chilled water.

[0122] The valve body is preferably an electromagnetic valve because of its fast response speed, precise control, and easy integration into the automation system. The electromagnetic valve realizes the rapid opening and closing of the valve through the on-off of the electromagnetic coil, has good sealing performance and a long service life, and is suitable for the precise regulation of water flow in the water treatment equipment 10. The structural form of the electromagnetic valve can include two types: direct-acting type and pilot-operated type. The specific selection can be flexibly determined according to system pressure, flow demand, and cost considerations to meet the control requirements under different working conditions.

[0123] In the water treatment device 10 of this embodiment, the on-off control of multiple heat exchange channels of the heat exchange member 410 is realized through the liquid path control device, which can flexibly switch the water path according to different requirements, so as to achieve efficient heat conversion and reasonable distribution of pipelines. Specifically, the heat exchange member 410 is controlled by a switching valve to be connected or disconnected from any one of the water paths of the waste water end 212, the purified water end 213 or the water inlet 110. At the same time, the corresponding output water path is switched to be connected to the waste water outlet 120, the heat exchange assembly 420 or the water storage tank 300, and the independence of each heat exchange channel can be ensured.

[0124] The present invention also provides a water path control method for a water treatment device, which can be applied to the water treatment device 10 in any of the above embodiments. The water path control method specifically includes the following steps: Step S1: The liquid path control device switches the heat exchange member 410 to be respectively connected to the water sources output from the waste water end 212, the purified water end 213 and the water inlet 110 and separately conveys them through multiple heat exchange channels; Step S2: When the liquid path control device controls the first water source output from the waste water end 212 to input into the heat exchange member 410 along the first heat exchange channel 401, at least one of the following control modes is executed: Mode A1: Drive the first water source to circulate in the temperature regulating device 400; Mode A2: Drive the first water source to be discharged through the waste water outlet 120; Step S3: When the liquid path control device controls the second water source output from the purified water end 213 to input into the heat exchange member 410 along the second heat exchange channel 402, at least one of the following control modes is executed: Mode B1: Drive the second water source to circulate in the temperature regulating device 400; Mode B2: Drive the second water source to be discharged through the waste water outlet 120; Mode B3: Drive the second water source to be conveyed to the water storage tank 300; Step S4: When the liquid path control device controls the third water source output from the water inlet 110 to input into the heat exchange member 410 along the third heat exchange channel 403, at least one of the following control modes is executed: Mode C1: Drive the third water source to circulate in the temperature regulating device 400; Mode C2: Drive the third water source to be discharged through the waste water outlet 120; Mode C3: Drive the third water source to be conveyed to the filter element assembly 200.

[0125] The waterway control method provided by the present invention can flexibly execute various control modes by separately controlling multiple heat exchange channels of the heat exchange member 410, realizing the efficient flow and heat management of the waterway in the water treatment device 10. It not only improves the refrigeration speed and energy-saving performance, but also ensures the water quality safety and the hygiene management of the system to achieve functions such as heat exchange cycle, heat exchange waste discharge, filter element flushing, and water storage tank disinfection, significantly enhancing the comprehensive performance of the water treatment device. At the same time, multiple heat exchange channels can separately transport the heat exchange water source without affecting each other, and the use effect is good.

[0126] Further, the liquid path control device further includes a circulation valve 521, a refrigeration valve 522, a disinfection valve 523, a filter element valve 524, a heat exchange valve 525, a purified water input valve 526, and a waste water circulation valve 527, as well as a first waterway valve 531, a second waterway valve 532, and a third waterway valve 533. The waterways of the water treatment device 10 in this embodiment are constituted as follows: The fourth heat exchange channel 404, the circulation pump 421, and the heat exchange water tank 422 are connected in sequence to form a circulation loop, and the circulation valve 521 is arranged on the circulation loop; The purified water end 213 is connected to the input end of the water storage tank 300 to form a cold water input waterway; the refrigeration valve 522 is arranged on the cold water input waterway; The second heat exchange channel 402 is connected to the input end of the water storage tank 300 to form a disinfection waterway; the disinfection valve 523 is arranged on the disinfection waterway; The second heat exchange channel 402 is connected to the water inlet end 211 to form a filter element return waterway; the filter element valve 524 and the filter element booster pump 220 are arranged on the filter element return waterway; The waste water end 212 is connected to the first heat exchange channel 401 to form a waste water heat exchange waterway; the heat exchange valve 525 is arranged on the waste water heat exchange waterway; The purified water end 213 is connected to the second heat exchange channel 402 to form a purified water heat exchange waterway; the purified water input valve 526 is arranged on the purified water heat exchange waterway; The first heat exchange channel 401, the second heat exchange channel 402, and the third heat exchange channel 403 are respectively connected to the waste water outlet 120 to form a first waste water output waterway, a second waste water output waterway, and a third waste water output waterway; the first waterway valve 531, the second waterway valve 532, and the third waterway valve 533 are respectively arranged on the first waste water output waterway, the second waste water output waterway, and the third waste water output waterway; the pipeline between the first waterway valve 531 and the waste water valve 512 is further connected to the heat exchange water tank 422, and the waste water circulation valve 527 is arranged on this pipeline to transport the heat exchange water to the heat exchange water tank 422. Similarly, the water bodies output by the second waterway valve 532 and the third waterway valve 533 can also be transported to the heat exchange water tank 422, so that the heat exchange water can perform internal circulation in the temperature control device 400.

[0127] The operating principle of the water treatment device 10 is as follows: When driving the heat exchange water source to exchange heat through the heat exchanger 410, first close the refrigeration valve 522 to prevent the heat exchange water source from entering the water storage tank 300, thereby preventing the low-temperature water in the water storage tank 300 from being affected by unnecessary heat and maintaining the stability of the water temperature and the quality of cold water in the water storage tank 300.

[0128] When it is necessary to drive the first water source (which can be wastewater) output from the wastewater end 212 to enter the heat exchanger 410 for heat exchange; Close: the wastewater valve 512; Open: the heat exchange valve 525, the first waterway valve 531, and the wastewater circulation valve 527; The first water source can then enter the heat exchanger 410 for heat exchange.

[0129] At this time, the liquid path control device can switch the output water path to mode A1: Open: the circulation valve 521; Thereby, the heat exchange water source can be driven to circulate in the temperature control device 400 to achieve the heat exchange function.

[0130] At this time, the liquid path control device can switch the output water path to mode A2: Open: the wastewater valve 512, the first waterway valve 531; Thereby, the heat exchange water source can be driven to discharge wastewater through the wastewater end 212.

[0131] When it is necessary to drive the second water source (which can be purified water) output from the purified water end 213 to enter the heat exchanger 410 for heat exchange; Close: the refrigeration valve 522; Open: the purified water input valve 526, the second waterway valve 532, and the wastewater circulation valve 527; The second water source can then enter the heat exchanger 410 for heat exchange.

[0132] At this time, the liquid path control device can switch the output water path to mode B1: Open: the circulation valve 521; Thereby, the heat exchange water source can be driven to circulate in the temperature control device 400 to achieve the heat exchange function.

[0133] At this time, the liquid path control device can switch the output water path to mode B2: Open: the wastewater valve 512, the second waterway valve 532; Thereby, the heat exchange water source can be driven to discharge wastewater through the wastewater end 212.

[0134] At this time, the liquid path control device can switch the output water path to mode B3: Close: the second waterway valve 532; Open: the disinfection valve 523; Thus, the heat exchange water source can be driven to be transported to the water storage tank 300 for high-temperature disinfection.

[0135] When it is necessary to drive the third water source (which can be tap water) input from the water inlet 110 to enter the heat exchange member 410 for heat exchange; Open: the water inlet valve 511, the third water path valve 533, and the waste water circulation valve 527; The third water source can then enter the heat exchange member 410 for heat exchange.

[0136] At this time, the liquid path control device can switch the output water path to mode C1: Open: the circulation valve 521; Thus, the heat exchange water source can be driven to circulate in the temperature control device 400 to achieve the heat exchange function.

[0137] At this time, the liquid path control device can switch the output water path to mode C2: Open: the waste water valve 512, the third water path valve 533; Thus, the heat exchange water source can be driven to discharge waste water through the waste water end 212.

[0138] At this time, the liquid path control device can switch the output water path to mode C3: Close: the purified water valve 513, the purified water input valve 526, the third water path valve 533; Open: the filter element valve 524, the refrigeration valve 522; Thus, the heat exchange water source can be driven to be transported to the filter element assembly 200 for filtration, and the filtered heat exchange water is transported to the water storage tank 300.

[0139] Specifically, for example, when the temperature of the heat exchange water source exceeds the preset threshold, the liquid path control device switches to modes A2, B2, and C2. The water flows through the heat exchange member 410 and then discharges from the waste water port 120, forming a unidirectional flowing heat exchange water path. This unidirectional transportation mode helps to quickly remove the excessive heat in the heat exchange water source. By utilizing the characteristics of the lower temperature and larger flow rate of the external water source, the temperature of the heat exchange water source is rapidly reduced, preventing the overall temperature of the system from being too high and improving the safety and stability of the equipment. In this mode, the heat exchange efficiency and the heat exchange effect of the heat exchange member 410 can be improved, ensuring the continuous transportation of the heat exchange water source and the timely discharge of the waste water, and avoiding water flow stagnation and reduction of the heat exchange efficiency.

[0140] When the temperature of the heat exchange water source does not exceed the threshold, modes A1, B1, and C1 can be adopted. The heat exchange water source forms a closed-loop circulation and transportation between the heat exchange member 410 and the heat exchange water tank 422. At this time, the heat exchange water source continuously flows through the heat exchange loop, effectively maintaining the temperature of the heat exchange water source uniform and stable, reducing the influence of temperature fluctuations on the system, and improving the overall heat exchange efficiency and energy-saving effect.

[0141] When the temperature of the heat exchange water source does not exceed the threshold, Mode B3 can also be adopted. The purified water for heat exchange can be transported to the storage tank 300 after heat exchange, and the storage tank 300 can be disinfected by high temperature, making full use of the heat energy.

[0142] When the temperature of the heat exchange water source does not exceed the threshold, Mode C3 can also be adopted. The purified water for heat exchange can be transported to the filter element assembly 200 after heat exchange, and the filter element assembly 200 can be flushed by high temperature to improve the flushing effect. The advantage of this flushing process is that the water source output by the heat exchange component 410 is used as the flushing medium. After the water temperature is adjusted by heat exchange, it is usually in a suitable temperature range, which helps to improve the flushing effect, promote the stripping of sediments and impurities in the filter element, and extend the service life of the filter element. At the same time, the flushing process precisely controls the water flow path and flow rate through the liquid path control device, enabling efficient and uniform flushing, avoiding local scaling and blockage phenomena, and ensuring the filtration performance and water quality safety of the filter element. The technical solution of flushing the filter element assembly 200 with warm water or hot water can significantly improve the cleaning effect and service life of the filter element. Specifically, compared with normal temperature water, warm water or hot water has stronger dissolution ability and higher heat energy transfer efficiency, which makes organic pollutants, oil substances and some microorganisms on the filter element easier to be dissolved and stripped, so as to achieve a more thorough flushing effect.

[0143] In practical applications, the temperature of warm water can be set within a general warm water range, such as 30°C, 40°C, 50°C, or even higher 60°C. The specific temperature is determined according to the heat resistance of the filter element material and the design requirements of the water purification system. If the temperature is too low, the flushing effect is limited and it is difficult to effectively remove the attached dirt; if the temperature is too high, it may cause damage or premature aging to some filter element materials. Therefore, it is necessary to reasonably control the temperature range to balance the flushing effect and the durability of the filter element.

[0144] In addition, flushing with hot water can also play a certain role in sterilization and disinfection. When the water temperature reaches a certain threshold (such as 55°C to 70°C), it can effectively inhibit and kill bacteria and microorganisms on the surface of the filter element, reduce the risk of secondary pollution, and thus ensure the hygienic safety and water quality stability of the water purification system. This disinfection function is especially suitable for occasions with high requirements for water quality hygiene, such as domestic drinking water, medical or food processing water, etc.

[0145] It should be noted that the number of valves of the circulation valve 521, the refrigeration valve 522, the disinfection valve 523, the filter element valve 524, the heat exchange valve 525, and the purified water input valve 526 can be set to one, two, or more according to the specific system design requirements. The specific number and layout can be flexibly adjusted according to the structure of the heat exchange element 410, the pipeline complexity, and the flow rate requirements to achieve more accurate flow path switching and more efficient heat exchange effects. The valves are preferably solenoid valves with fast response speed and good sealing performance, and are combined with the control module to achieve automatic control, further improving the intelligent level and operation efficiency of the system.

[0146] In summary, through the reasonable combination and linkage control of the above-mentioned circulation valve 521, refrigeration valve 522, disinfection valve 523, filter element valve 524, heat exchange valve 525, purified water input valve 526, and the water inlet valve 511, wastewater valve 512, purified water valve 513, and cold water valve 514, the flexible switching between the two modes of unidirectional flow cooling and closed-loop circulation transportation of the heat exchange water source in the heat exchange element 410 is realized, and the water volume and temperature of the circulating water source are ensured to be stable by supplementing wastewater and tap water, effectively improving the heat exchange efficiency, system energy saving, and operation safety, and significantly improving the overall performance of the water treatment equipment and the user experience.

[0147] Of course, during the process of discharging wastewater, in order to avoid the mutual influence between multiple heat exchange channels, during the process of discharging waste separately, the water path valves of other heat exchange channels can also be closed. For example, when the first heat exchange channel 401 discharges waste, the second water path valve 532 and the third water path valve 533 can be closed; the control methods of other heat exchange channels are the same as above and will not be elaborated here. In addition, since the multiple heat exchange channels of the heat exchange element 410 are independently arranged, during the operation of the water treatment equipment 10, each heat exchange channel can also be driven to be independently transported according to the needs without mutual influence.

[0148] Of course, in some embodiments, to ensure that the air or gas generated in the cold storage part 320 and the heat exchange water tank 422 due to water source consumption, temperature change, or gas accumulation can be effectively discharged, an exhaust device can also be provided in the water treatment equipment 10.

[0149] It can be connected to the exhaust ports of the cold storage part 320 and the heat exchange water tank 422 through an exhaust pipeline, and the gas can be discharged to the external environment through a set exhaust valve or an automatic exhaust device to ensure that the gas in the water body does not accumulate and avoid affecting the normal operation of the system.

[0150] The specific implementation method may include arranging exhaust pipes in the cold storage part 320 and the hot water exchange tank 422. Exhaust valves or exhaust holes are equipped along the exhaust pipes. The valves can adopt automatic exhaust valves controlled electrically, pneumatically or manually, so as to automatically open for exhaust according to the gas accumulation situation. The exhaust pipes can be reasonably arranged to ensure that the exhaust ports are far away from heat sources and areas vulnerable to pollution, avoiding gas backflow or introducing pollution. As the water source is continuously used and the temperature changes, air or dissolved gases in the cold storage part 320 and the hot water exchange tank 422 will gradually accumulate, affecting the stability of water flow and heat transfer efficiency. By arranging the exhaust pipes to lead these gases out of the system, the concentration of gases in the water body can be effectively reduced, the formation of bubbles can be reduced, water flow blockage and noise can be avoided, and the operation stability and heat exchange efficiency of the system can be improved.
