[0002] Most existing water purification equipment uses air cooling to regulate the temperature of the water storage device, typically employing fans and heat sinks to cool or refrigerate the water tank. This air-cooling system relies on air convection to remove heat, has a relatively simple structure, low manufacturing cost, and is easy to maintain. However, air cooling is greatly affected by ambient temperature, especially at high ambient temperatures, where the heat dissipation efficiency of the air-cooling system decreases significantly, making it difficult to stably control the water temperature and affecting the consistency of the water outlet temperature and the overall performance of the water purification equipment.

[0003] Furthermore, the large size of components such as fans and heat sinks in existing air-cooled structures occupies a significant amount of internal space, limiting the compact design of the overall water purification equipment and increasing its size and weight. This makes it difficult to meet users' demands for miniaturized and portable water purification equipment. Additionally, during long-term operation, wear and tear and noise from mechanical components such as fans in air-cooled systems also affect the equipment's lifespan and user experience. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Existing water treatment equipment mostly uses air cooling to regulate the temperature of the water storage tank, typically employing fans and heat sinks to cool or refrigerate the tank. This air-cooling system relies on air convection to remove heat, has a relatively simple structure, low manufacturing cost, and is easy to maintain. However, air cooling is significantly affected by ambient temperature, especially at high temperatures, where the heat dissipation efficiency of the air-cooling system decreases significantly, making it difficult to stably control the water temperature and affecting the consistency of the water treatment equipment's outlet temperature and its overall performance.

[0031] Furthermore, the large size of components such as fans and heat sinks in existing air-cooled structures occupies a significant amount of internal space, limiting the compact design of the overall water treatment equipment and increasing its size and weight. This makes it difficult to meet users' demands for miniaturized and portable water treatment equipment. Additionally, during long-term operation, wear and tear and noise from mechanical components such as fans in air-cooled systems also affect the equipment's lifespan and user experience.

[0032] Based on this, see Figures 1 to 2 As shown, this utility model embodiment provides a water treatment device 10, which includes a water storage device 100 and a temperature control device 200; the temperature control device 200 includes a heat exchange structure 210 and a heat exchange component 220, the heat exchange structure 210 has a first heat exchange end and a second heat exchange end, the first heat exchange end is thermally coupled to the water storage device 100, and the second heat exchange end is thermally coupled to the heat exchange component 220; wherein, the heat exchange structure 210 includes a first heat exchange element 211 and a second heat exchange element 212, the first heat exchange element 211 and the second heat exchange element 212 are thermally coupled.

[0033] The water treatment equipment 10 of this embodiment adopts a heat exchange structure 210 with dual cooling components stacked. Through thermal coupling between the first heat exchange component 211 and the second heat exchange component 212, one cooling component cools the other, significantly increasing the temperature difference between the two ends, thereby improving the heat exchange effect of the heat exchange component 220. Compared with the temperature regulation scheme of air cooling in the traditional water treatment equipment 10, the heat exchange structure 210 of this embodiment replaces air cooling with liquid heat exchange, avoiding the influence of ambient temperature on heat dissipation efficiency, and can more stably control the temperature of the water storage device 100, improving the stability and consistency of the outlet water temperature.

[0034] Furthermore, the heat exchange structure 210 of this embodiment is compact in size, replacing the space-consuming fan and heat sink assembly in traditional air-cooled systems, reducing the overall size of the water treatment equipment 10, and facilitating the miniaturization design of the water treatment equipment 10. Since there are no moving parts such as mechanical fans, the structure of this embodiment reduces operating noise and mechanical wear, improving the service life and operational reliability of the equipment.

[0035] In one embodiment, the first heat exchange end is disposed on the side of the first heat exchange element 211 away from the second heat exchange element 212, and the second heat exchange end is disposed on the side of the second heat exchange element 212 away from the first heat exchange element 211. This structural arrangement has significant technical advantages and implementation principles.

[0036] Specifically, the first heat exchanger 211 and the second heat exchanger 212 are thermally coupled to form a tight heat conduction path. The first heat exchange end and the second heat exchange end are located at the relatively far ends of the two heat exchangers, ensuring that the heat exchange structure presents a superimposed and uniformly distributed heat exchange surface in space. The purpose of this design is to maximize the utilization of the thermal difference between the two cooling elements, effectively transferring the heat from the water storage device 100 to the second heat exchanger 212 through the first heat exchanger 211, and then the second heat exchanger 212 and the heat exchange assembly 220 undergo efficient heat exchange.

[0037] This arrangement significantly improves the temperature difference between the two ends of the heat exchange structure 210, enhancing the overall heat transfer efficiency. The side of the first heat exchange end furthest from the second heat exchange element 212 avoids heat short-circuiting or localized heat accumulation, promoting uniform heat transfer. The side of the second heat exchange end furthest from the first heat exchange element 211 allows the heat exchange assembly 220 to more fully dissipate or absorb heat, improving its cooling or heating effect.

[0038] Furthermore, the first and second heat exchange ends are respectively located on the side of their respective heat exchange components furthest from each other, which contributes to the compact and rational layout of the overall heat exchange structure 210, maximizing the utilization of the internal space of the equipment. This design reduces the internal thermal resistance of the heat exchange structure, improves heat exchange efficiency, and avoids the problems of increased volume and uneven heat dissipation caused by excessive overlap of heat exchange elements.

[0039] In this embodiment, the number of the first heat exchanger 211 and the second heat exchanger 212 can be one, two, or more, and the specific number can be determined according to the capacity of the water storage device 100 and the heat exchange requirements. Setting up multiple heat exchangers can expand the heat exchange area and enhance heat exchange efficiency, which is especially suitable for temperature regulation of large-capacity water storage devices, ensuring temperature uniformity and response speed. Furthermore, the series or parallel combination of multiple heat exchangers can be flexibly designed to adapt to different spatial layouts and thermal management requirements.

[0040] In one embodiment, the first heat exchanger 211 includes a first semiconductor refrigeration chip, the second heat exchanger 212 includes a second semiconductor refrigeration chip, and the cooling end of the second semiconductor refrigeration chip is thermally coupled to the heating end of the first semiconductor refrigeration chip.

[0041] In this embodiment, both the first heat exchanger 211 and the second heat exchanger 212 are semiconductor refrigeration chips, and effective heat transfer and temperature regulation are achieved through the thermoelectric effect of the semiconductor refrigeration chips.

[0042] Specifically, the cold end of the first heat exchanger 211 is thermally coupled to the water storage device 100, meaning that the cold end of the first heat exchanger 211 can be in close contact with the outer or inner wall of the water storage device 100, absorbing heat within the water storage device 100 through heat conduction, thereby achieving the purpose of lowering the water storage temperature. Simultaneously, the hot end of the first heat exchanger 211 is thermally coupled to the cold end of the second heat exchanger 212, meaning that the hot end of the first heat exchanger 211 is directly in contact with the cold end of the second heat exchanger 212 or connected through a high thermal conductivity material, enabling heat transfer from the hot end of the first heat exchanger 211 to the cold end of the second heat exchanger 212.

[0043] During this process, the cold end of the second heat exchanger 212 absorbs heat from the hot end of the first heat exchanger 211 and is then cooled, while the hot end of the second heat exchanger 212 releases excess heat to the external environment or other heat exchange media through thermal coupling with the heat exchange assembly 220. Thus, the first heat exchanger 211 and the second heat exchanger 212 form a superimposed thermal loop. The cooling end of the first heat exchanger 211 directly cools the water storage device 100, while the cold end of the second heat exchanger 212 cools the hot end of the first heat exchanger 211, thereby significantly increasing the temperature difference between the two ends and enhancing the overall cooling effect.

[0044] The specific implementation using semiconductor cooling chips as the first heat exchanger 211 and the second heat exchanger 212 has several advantages. Semiconductor cooling chips have a compact structure, no moving mechanical parts, extremely low noise during operation, and a fast cooling response, making them suitable for water treatment equipment applications requiring high outlet water temperature and rapid adjustment. Furthermore, semiconductor cooling chips are easy to modularize, allowing for adjustments to cooling capacity and heat exchange structure dimensions based on the capacity and temperature control requirements of the water storage device 100, thus improving system flexibility and adaptability.

[0045] Furthermore, the thermal coupling between the first heat exchanger 211 and the second heat exchanger 212 can be achieved using thermally conductive silicone, thermal paste, or a high thermal conductivity metal clamp, ensuring minimal thermal resistance and improving heat transfer efficiency. A well-designed thermal coupling not only guarantees effective heat transfer but also prevents localized overheating or reduced cooling performance due to poor contact.

[0046] The design of the aforementioned semiconductor cooling chip superimposed heat exchange structure effectively overcomes the cooling efficiency fluctuations caused by changes in ambient temperature in traditional air-cooled systems, improving the temperature control accuracy of the water storage device 100 and the consistency of the outlet water temperature. Simultaneously, the compact structure and absence of moving mechanical parts reduce equipment noise and maintenance costs, extend the service life of the water treatment equipment 10, and meet the comprehensive requirements of modern water purification equipment for high efficiency, quiet operation, and miniaturization.

[0047] In another embodiment, the first heat exchanger 211 is a semiconductor refrigeration chip, and the second heat exchanger 212 is a compressor refrigeration machine, with the cooling end of the compressor refrigeration machine thermally coupled to the heating end of the first heat exchanger 211. This configuration constitutes a composite dual-refrigeration-component superimposed heat exchange structure.

[0048] Specifically, the thermoelectric cooler, acting as the first heat exchanger 211, operates based on the Peltier effect. It generates a temperature difference across its two sides via an electric current, achieving cooling or heating functions. The thermoelectric cooler is small in size, has a fast response speed, and high control precision, making it suitable for precise temperature regulation of the water storage device 100. The heat generated at its heating end needs to be effectively transferred; otherwise, the cooling efficiency and equipment stability will be affected.

[0049] The second heat exchanger 212 employs a compressor refrigerator, a traditional and efficient mechanical refrigeration device capable of generating a large cooling capacity. The cooling end of the compressor refrigerator is thermally coupled to the heating end of the thermoelectric cooler, aiming to directly transfer the heat generated by the heating end of the thermoelectric cooler to the cooling end of the compressor refrigerator for secondary cooling. Through this structural design, the compressor refrigerator undertakes the task of dissipating heat from the heating end of the thermoelectric cooler, avoiding heat accumulation that could lead to performance degradation of the thermoelectric cooler.

[0050] This composite heat exchange structure forms a cascaded refrigeration system by thermally coupling a semiconductor cooling chip and a compressor chiller in series. The semiconductor cooling chip is responsible for rapid and precise temperature control of the water storage device 100, while the compressor chiller efficiently removes heat from the heating end of the semiconductor cooling chip, significantly improving overall heat exchange efficiency and refrigeration performance. This design not only expands the controllable temperature range but also enhances the system's adaptability to changes in ambient temperature, ensuring the stability and consistency of the outlet water temperature.

[0051] This composite heat exchange structure not only improves heat exchange efficiency but also reduces equipment size and noise. The semiconductor cooling chip is small and has no moving mechanical parts, resulting in extremely low noise. While the compressor has moving mechanical parts, its noise level is kept within acceptable ranges through reasonable vibration isolation and noise control design. Overall, compared to traditional single-air-cooling systems, this structure reduces reliance on fans and heat sinks, lowers equipment size, and improves structural compactness.

[0052] Furthermore, the thermal coupling method of this structure ensures a short heat transfer path and low thermal resistance, reducing energy loss and improving energy efficiency. Simultaneously, the combination of the semiconductor cooling chip and the compressor refrigerator enriches temperature control methods, enabling the water purifier 10 to flexibly adjust the temperature using individual or combined cooling modes according to actual needs, thereby improving equipment applicability and user experience.

[0053] In one embodiment, the water storage device 100 consists of a cold water tank and a hot water tank to achieve independent temperature control. Specifically, a first heat exchange end is thermally coupled to the cold water tank, and a second heat exchange end is thermally coupled to the hot water tank. This design allows the cold water tank and the hot water tank to regulate their temperatures in relatively independent environments, thereby improving the overall performance and user experience of the water treatment device 10.

[0054] The cooling of the cold water tank is achieved through heat exchange between the cold end of the first heat exchanger 211 and the cold water tank. By effectively thermally coupling the first heat exchanger 211 with the cold water tank, heat within the tank is absorbed, thus lowering the water temperature. This process relies on the thermoelectric effect of the semiconductor cooling chip; through the flow of current, the cold end absorbs heat while the hot end releases heat, resulting in highly efficient cooling. As the temperature of the cold water tank decreases, users can obtain cooler drinking water, meeting their daily needs.

[0055] Meanwhile, the heat exchange between the hot end of the second heat exchanger 212 and the hot water tank achieves the heating of the hot water tank. By effectively thermally coupling the hot end of the second heat exchanger 212 with the hot water tank, its heat can be efficiently transferred to the hot water tank, raising the water temperature. This design not only ensures that the hot water tank can be heated quickly when needed, but also keeps the temperature of the hot water tank within the comfortable range required by the user.

[0056] Specifically, the operating states of the first heat exchanger 211 and the second heat exchanger 212 can be adjusted by controlling the magnitude of the current to achieve different cooling and heating effects. It should be noted that the number of the first heat exchanger 211 and the second heat exchanger 212 can be one, two, or more; there is no single limitation. Using multiple heat exchangers can further improve the cooling and heating efficiency of the cold water tank and the hot water tank, enhancing the system's flexibility and adaptability. For example, if the number of first heat exchangers 211 is increased to two, its cooling capacity will be significantly enhanced, thereby reducing the temperature of the cold water tank more quickly; similarly, if the number of second heat exchangers 212 is increased, the heating efficiency of the hot water tank will also be improved, enabling a faster response to the user's hot water demand.

[0057] Furthermore, the thermal coupling between heat exchangers 211 and 212 can be achieved using thermally conductive silicone, thermal paste, or high thermal conductivity metal materials to ensure minimal thermal resistance while improving heat transfer efficiency. A well-designed thermal coupling not only guarantees effective heat transfer but also prevents localized overheating or unstable temperature control due to poor contact.

[0058] Through the above design, the water storage device 100 can achieve efficient temperature regulation. The coordinated work of the first heat exchanger 211 and the second heat exchanger 212 enables independent and precise temperature control of cold water and hot water, meeting the multiple needs of modern users for drinking water temperature and usage efficiency.

[0059] In one embodiment, the cold water tank includes a refrigeration section 111 and a cold storage section 112, and the refrigeration section 111 and the cold storage section 112 are connected. The refrigeration section 111 is thermally coupled to the first heat exchange end to form an overall temperature regulation structure.

[0060] Specifically, the refrigeration unit 111 primarily functions to cool the water source. Through thermal coupling with the first heat exchange end, the refrigeration unit 111 can effectively transfer the cooling energy transferred by the heat exchange structure 210 into the water body within the water storage device 100, achieving a rapid decrease in water temperature. During the cooling process, the water source's temperature is lowered as it passes through the refrigeration unit 111, forming cold water.

[0061] The chilled water then flows or is transferred to a cold storage section 112, which is connected to the refrigeration section 111, for preservation and storage. The cold storage section 112, as a storage area for chilled water, effectively maintains a stable water temperature, preventing rapid increases in temperature due to fluctuations in the ambient temperature, thereby ensuring that the water temperature at the outlet of the water treatment equipment 10 remains within the required constant low-temperature range. The capacity and shape of the cold storage section 112 can be designed according to actual needs to achieve long-term chilled water preservation without significantly increasing the equipment volume.

[0062] The interconnected design of the refrigeration unit 111 and the cold storage unit 112 allows the cold water generated by the refrigeration unit 111 to flow smoothly into the cold storage unit 112. At the same time, the cold water in the cold storage unit 112 can also be returned or transported to the outlet of the water treatment equipment 10 by flow when needed, thereby ensuring that the temperature of the water source taken by the user is constant and comfortable.

[0063] Through the partitioned design of the refrigeration unit 111 and the cold storage unit 112, the water treatment equipment 10 can achieve the dual functions of "instant cooling" and "cold water storage and insulation." This satisfies users' needs for rapid cooling while ensuring a continuous supply of chilled water through the cold storage unit 112, thus improving the equipment's ease of use and energy efficiency. Furthermore, the refrigeration unit 111 focuses on the cooling process, while the cold storage unit 112 focuses on chilled water storage; this clear division of labor facilitates optimized system thermal management and control strategies.

[0064] Furthermore, the water storage device 100 also includes a first water storage pump 120, which is connected to both the refrigeration section 111 and the cold storage section 112, and the refrigeration section 111 and the cold storage section 112 are interconnected. By providing the first water storage pump 120, the water source inside the water storage device 100 can be actively driven to circulate between the refrigeration section 111 and the cold storage section 112. This circulation mechanism promotes the uniform distribution and transfer of water temperature, effectively avoiding uneven temperature or local overcooling or overheating within the refrigeration section 111 and the cold storage section 112, thereby improving the overall temperature control efficiency and system stability.

[0065] Specifically, the driving action of the first water pump 120 enables the water source cooled by the refrigeration unit 111 to be quickly transported to the cold storage unit 112 for cold water storage. At the same time, the cold water in the cold storage unit 112 can also flow back to the refrigeration unit 111 for recooling, forming a closed loop. This design not only accelerates the rate of water temperature drop but also improves refrigeration efficiency.

[0066] The type of the first water storage pump 120 can also be varied, such as a centrifugal pump, diaphragm pump, or gear pump. The specific selection can be optimized based on the pump's reliability, energy consumption level, and ease of maintenance. Using a high-efficiency and energy-saving pump not only reduces operating costs but also ensures the long-term stable operation of the system.

[0067] In addition, in one embodiment, the water storage device 100 further includes a second water storage pump 130, which is connected to the cold storage section 112 and used to pump out cold water. The second water storage pump 130 enables the cold water in the cold storage section 112 to be effectively extracted and transported to the outlet of the water treatment equipment 10 or other parts that require low-temperature water, realizing the output and utilization of cold water. The second water storage pump 130 can intelligently adjust the flow rate according to the user's water demand, ensuring the stability of water supply and the constantness of water temperature. Through the coordinated work of the first water storage pump 120 and the second water storage pump 130, the cooling water circulation and cold water output inside the water storage device 100 are efficiently coordinated, ensuring both the dynamic balance of heat transfer and cold water storage between the cooling section 111 and the cold storage section 112, and achieving a stable output of cold water.

[0068] In one embodiment, the heat exchange assembly 220 includes a heat exchange pipe 221, which forms a closed heat exchange loop by connecting to the heat exchange structure 210. Specifically, the heat exchange pipe 221 is at least partially housed within the hot water tank or in direct contact with the hot water tank, thereby achieving efficient heat exchange. The heat exchange pipe 221 can be structurally designed using materials with excellent thermal conductivity, such as copper, stainless steel, or aluminum alloy pipes, to ensure rapid heat transfer and efficient conduction.

[0069] During the cooling process, coolant (such as water or a special coolant) can be transported inside the heat exchange pipe 221, circulating along the loop between the heat exchange structures 210, thereby removing heat from the hot water tank and lowering the water temperature. The principle of this scheme is to utilize the continuous flow of coolant in the pipes, transferring heat energy from the water tank to the coolant through contact or indirect conduction between the heat exchange pipes and the water source, and then dissipating heat through the cold end of the heat exchange structure 210 to achieve the cooling effect.

[0070] In some specific embodiments, the heat exchange pipes 221 can pass through the wall of the hot water tank, utilizing heat conduction to directly contact the water source for heating or cooling. For example, the heat exchange pipes 221 can pass through the wall of the hot water tank, achieving close contact with the water source through thermally conductive adhesive or highly thermally conductive materials, thereby conducting heat and directly transferring heat to the water source to achieve the heating function. Alternatively, the heat exchange pipes 221 can be arranged along a specific path inside the hot water tank, forming multiple contact points to increase the heat exchange area and efficiency.

[0071] In heating applications, heat exchange pipes 221 can transfer heat to the water source via conduction or convection through hot water flowing through the hot water tank or other heat sources, thereby rapidly increasing the water temperature. This design can meet users' immediate demand for hot water and is suitable for scenarios requiring rapid heating. The contact method between the heat exchange pipes and the hot water tank can adopt direct contact, clamping, or encasing structures to ensure efficient heat transfer.

[0072] Furthermore, to ensure the heat exchange efficiency of the heat exchange pipes 221, the pipes can have a multi-layer structure or employ surface treatment techniques (such as roughening, coating, etc.) to increase the contact area with the water source or improve thermal conductivity. In practical applications, the arrangement of the heat exchange pipes 221 can be optimized according to the size and shape of the hot water tank, such as spiral, mesh, or parallel layouts, to maximize heat exchange efficiency.

[0073] In one embodiment, the temperature control device 200 further includes a hot water tank 222, which is disposed on the heat exchange pipeline 221 and is used to contain the water source output by the heat exchange structure 210. By setting up the hot water tank 222, the hot water source can be temporarily stored and buffered, thereby improving the thermal management effect and operational stability of the system.

[0074] The hot water tank 222 effectively regulates the flow rate and temperature fluctuations of the heat exchange medium, avoiding the impact of momentary instability in the medium flow in the heat exchange pipeline 221 on heat exchange efficiency, thereby ensuring more uniform and efficient heat exchange between the heat exchange structure 210 and the water storage tank. Specifically, by storing a certain capacity of water, the hot water tank 222 provides a buffer when heat exchange demand changes, reducing frequent system start-ups and shutdowns, extending equipment life, and reducing energy consumption.

[0075] In addition, the material of the hot water exchange tank 222 should be corrosion-resistant, pressure-resistant, and have good thermal conductivity, such as food-grade plastic, stainless steel, or aluminum alloy, to ensure its safety and stability during long-term operation. The shape and arrangement of the hot water exchange tank 222 can also be diversified, for example, it can be designed as a cylindrical, square, or flat shape, specifically optimized according to the internal space structure of the water treatment equipment 10 and the layout of the heat exchange pipeline 221, so as to achieve a compact design and good heat exchange effect.

[0076] By installing a heat exchange tank 222 in the heat exchange pipeline 221, not only is the heat capacity and adjustment flexibility of the heat exchange system improved, but noise and vibration problems caused by excessive flow rate of the heat exchange medium are also effectively prevented, thus improving the comfort and reliability of the system. Combined with the cooling and heating switching function achieved by the semiconductor cooling chip in the heat exchange structure 210, the heat exchange tank 222 can serve as a medium for temporary heat storage and equalization, making the thermal management capability of the entire temperature control device 200 more precise and efficient, meeting the water treatment equipment 10's requirements for fine-grained water temperature control under various operating conditions.

[0077] In one embodiment, the hot water tank 222 can be integrated with the hot water tank, serving both as a container for the heat exchange medium and as a storage and output unit for domestic hot water. This design achieves structural integration and functional diversification, greatly simplifying the internal structure of the water treatment equipment and reducing system complexity and manufacturing costs.

[0078] Specifically, when a user needs hot water, the hot water exchange tank 222, through thermal coupling with the heat exchange pipe 221 and heat exchange structure 210, directly stores the water heated by the hot water source inside the tank. The hot water is then directly output from the hot water exchange tank 222 to meet the user's water needs. Since the hot water exchange tank 222 itself is a hot water tank, heat loss during the transfer of hot water between multiple containers is avoided, thereby improving thermal efficiency and the stability of the outlet water temperature.

[0079] Furthermore, when the water source is purified water, the hot water tank 222 not only serves as a heat exchange container but can also directly store and output hot water that meets drinking standards, achieving a seamless integration of water purification and heating functions. The inner wall material and structural design of the hot water tank 222 must meet drinking water safety standards, preferably using food-grade stainless steel, food-grade polymer materials, or materials with special coatings to ensure water quality safety and equipment durability.

[0080] By integrating the functions of the heat exchange tank 222 and the hot water tank, the integration and functionality of the water treatment equipment are improved. Furthermore, by reducing heat exchange links, heat loss is reduced, thus enhancing the overall energy efficiency of the system. Simultaneously, this design facilitates rapid hot water supply and precise temperature control, thereby meeting modern users' demands for efficient, energy-saving, and convenient hot water supply.

[0081] In summary, the combined design of the heat exchange tank 222, as a hot water tank, fully leverages the synergistic effect of the heat exchange structure and the water storage structure, simplifies the equipment structure, reduces manufacturing and maintenance costs, and improves the stability and safety of hot water output.

[0082] Furthermore, the temperature control device 200 further includes a condensation component 230, which is disposed inside the water treatment equipment 10 and arranged opposite to the heat exchange structure 210, for effectively collecting condensate generated on the surface of the heat exchange structure 210. Specifically, when the first heat exchanger 211 and the second heat exchanger 212 are in operation, as the temperature at the cooling end drops below the dew point, water vapor in the air will condense on their surfaces to form condensate. At this time, the condensation component 230 plays a crucial role, collecting the condensate in a timely manner through its coordinated operation with the heat exchange structure 210, preventing the condensate from affecting other components inside the water treatment equipment or causing leakage problems.

[0083] The condenser assembly 230 is typically positioned close to or covering the condensation area of ​​the heat exchange structure 210. It guides condensate water to a pre-designed collection tank or pipe via gravity or capillary action, ensuring effective condensate water recovery and discharge. The condenser assembly 230 can adopt various structural forms, such as a metal plate with guide channels, a porous material with good water absorption, or a collection tank made of polymer. The specific form can be flexibly designed according to the structural space and water vapor environment conditions of the water treatment equipment 10.

[0084] By configuring the condenser assembly 230, the safety and stability of the heat exchange structure 210 can be significantly improved. Firstly, timely collection of condensate prevents dripping or accumulation that could cause short circuits or corrosion damage to electronic components, circuit boards, and other sensitive parts, extending the service life of the water treatment equipment 10. Secondly, reduced condensate retention inside the unit lowers the risk of bacterial growth, contributing to the hygiene of the water treatment equipment. Thirdly, the condenser assembly 230 helps maintain the dryness of the surface of the heat exchange structure 210, preventing the formation of a water film that could affect heat exchange efficiency and improve the overall stability of cooling and heating performance.

[0085] The material selection for the condenser assembly 230 should take into account corrosion resistance, ease of cleaning, and durability, with stainless steel, aluminum alloy, or food-grade plastic materials being preferred. Furthermore, to adapt to different working environments and structural layouts, the shape and size of the condenser assembly 230 can be designed in various specifications, such as a long strip water collection tank, a wraparound water collection belt, or a modular combination structure. Specific dimensions can be customized according to the internal space of the water treatment equipment 10.

[0086] In one embodiment, the condensation assembly 230 includes a water collection tray 231, which is disposed at the bottom of the heat exchange structure 210, with its opening facing the heat exchange structure 210 to effectively collect condensate generated on the surface of the heat exchange structure 210. The water collection tray 231 can quickly collect condensate through gravity or capillary guidance, preventing condensate from dripping onto other components of the water treatment equipment 10 and ensuring the dryness and safety of the equipment's interior.

[0087] The condensate collection tray 231 not only collects condensate, but also allows the collected condensate to gradually evaporate and be consumed within the tray through natural evaporation or auxiliary ventilation, reducing the risks associated with condensate accumulation. This design prevents condensate from remaining for extended periods, thus avoiding bacterial growth or unpleasant odors and improving the hygiene and safety of the water treatment equipment 10.

[0088] Specifically, the material of the water collection tray 231 should have good corrosion resistance and easy cleaning. Commonly used materials include stainless steel, aluminum alloy or food-grade plastic, to ensure that it does not deform, corrode or pollute the water quality during long-term use.

[0089] Furthermore, the water collection tray 231 can be designed with an inclined angle or equipped with a drain outlet, working in conjunction with the internal ventilation system of the water treatment equipment 10 or by adding a small fan to promote rapid evaporation of condensate. The inclined design helps condensate to collect and flow, while the drain outlet facilitates the discharge of condensate, preventing excessive water accumulation and the risk of overflow. For enclosed spaces or high-humidity environments, the water collection tray 231 can also be combined with moisture-absorbing materials or heating elements to further improve evaporation efficiency and ensure timely consumption of condensate.

[0090] The design of the opening of the water collection tray 231 facing the heat exchange structure 210 maximizes the collection efficiency of condensate, reduces the loss of condensate before it evaporates in the air, and prevents condensate from splashing and affecting other components. The reasonable size and shape of the opening also helps to prevent dust or impurities from entering the water collection tray, ensuring the purity of the condensate and the long-term stable operation of the water collection tray.

[0091] In one embodiment, the condensation assembly 230 further includes a flow guide 232, one end of which is connected to the heat exchange structure 210, and the other end is at least partially located within the water collection tray 231. This flow guide 232 efficiently guides the condensate generated on the surface of the heat exchange structure 210 into the water collection tray 231, achieving centralized collection and management of the condensate. By providing the flow guide 232, direct dripping of condensate can prevent other internal components from becoming damp or damaged, while also reducing condensate loss into the air and improving collection efficiency.

[0092] The specific structural form of the flow guide 232 can vary, with typical implementations including a pipe-like structure or materials utilizing capillary action. When used as a pipe, the flow guide 232 can be made of materials such as plastic pipe, stainless steel pipe, or silicone hose, possessing good corrosion resistance and mechanical strength, and reliably guiding the flow of condensate. The pipe-like flow guide 232 has the advantages of a clear flow path, convenient flow control, and easy installation and maintenance, making it suitable for heat exchange structures with relatively fixed spaces and regular layouts.

[0093] On the other hand, the guide element 232 can also be made of materials with capillary absorption properties, such as absorbent cotton, sponge, or capillary fiber cloth. These materials actively attract and conduct condensate using capillary action, allowing for flexible placement in complex or confined spaces. The capillary material guide element 232 not only effectively captures small water droplets but also slowly releases moisture to the collection tray 231, reducing the risk of splashing and overflow. Furthermore, the absorbent material also has a certain filtering and dust-blocking function, helping to improve the purity of the condensate and the cleanliness of the equipment's interior.

[0094] By cooperating with the guide component 232 and the water collection tray 231, efficient centralized management of condensate can be achieved. This not only avoids corrosion and damage to the internal electronic components and mechanical parts of the water treatment equipment 10 caused by condensate, but also reduces maintenance workload and improves the overall operational stability and service life of the equipment. At the same time, this design facilitates the natural evaporation or subsequent discharge of condensate, which is in line with the design concept of energy conservation and environmental protection.

[0095] In summary, the guide element 232 in the condensation assembly 230, whether in the form of a pipe or a capillary material, can effectively guide the condensate on the surface of the heat exchange structure 210 into the water collection tray 231, improving the condensate collection efficiency and the safety and reliability of the equipment. It provides a complete condensate management solution for the water treatment equipment 10, meeting the high requirements for equipment stability and ease of maintenance in practical applications.

[0096] Specifically, the water treatment device 10 also includes a filter cartridge assembly 300 for installing an external water purification filter cartridge. The purified water end of the filter cartridge assembly 300 is connected to a water storage tank, preferably to a cooling unit 111. This design aims to further enhance the water treatment capacity and user experience of the water treatment device 10 through a highly efficient filter cartridge system.

[0097] The filter cartridge assembly 300 includes a filter cartridge mounting base 310 and a filter cartridge booster pump 320. The filter cartridge mounting base 310 is used to securely mount various types of water purification filter cartridges, ensuring the filter cartridges remain stable during operation and can withstand water flow pressure. Simultaneously, the design of the filter cartridge mounting base 310 should facilitate user replacement of filter cartridges, reducing maintenance difficulty. Specifically, the filter cartridge mounting base 310 can be designed with a snap-on or screw-on fixing mechanism, allowing for quick disassembly and replacement by the user, and effectively preventing leakage.

[0098] The filter cartridge booster pump 320 is connected before the inlet end of the filter cartridge mounting base 310 to increase the inlet water pressure, especially when used with reverse osmosis (RO) membrane filter cartridges. RO membrane filter cartridges have high requirements for inlet water pressure; therefore, the booster pump can effectively increase the water pressure entering the filter cartridge, ensuring the working efficiency and water purification capacity of the RO membrane filter cartridge.

[0099] In practical applications, the design of the filter element assembly 300 can also consider setting multiple filter elements to achieve more comprehensive water treatment. In the above technical solution, the water treatment equipment 10 is also equipped with a filter element assembly 300 for installing external water purification filter elements. The purified water end (i.e., the output end) of the filter element assembly 300 is connected to a water storage tank, preferably connected to the refrigeration unit 111. This design fully considers the efficient use of filter elements and the optimization of the overall system performance, aiming to improve the water purification effect and the adaptability of the system.

[0100] Specifically, the filter cartridge assembly 300 includes a filter cartridge mounting base 310 and a filter cartridge booster pump 320. The filter cartridge mounting base 310 provides a stable and sealed mounting platform for installing different types of water purification filter cartridges, especially suitable for high-efficiency filtration elements such as reverse osmosis (RO) membrane filter cartridges. The filter cartridge booster pump 320 is connected before the inlet end of the filter cartridge mounting base 310. Its purpose is to increase the water pressure entering the filter cartridge by utilizing the pressure boosting effect of the booster pump, thereby ensuring that the filtration effect meets the expected water quality standards.

[0101] This booster pump is particularly suitable for use in RO membrane filter cartridges. RO membrane filter cartridges typically require high inlet water pressure to achieve effective filtration performance. By installing a booster pump before the filter cartridge, insufficient water pressure caused by pipeline resistance and pressure loss in the system can be effectively overcome, ensuring that the RO membrane filter cartridge operates within its optimal pressure range. This improves filtration efficiency, extends the filter cartridge's lifespan, and enhances the quality of the effluent.

[0102] In practical implementation, the filter element booster pump 320 can be of various types, such as a miniature centrifugal pump, a diaphragm pump, or a gear pump. The advantages of using a diaphragm pump are its compact structure, low noise, good corrosion resistance, and suitability for continuous operation environments.

[0103] Furthermore, the filter cartridge holder 310 should be designed with versatility in mind, supporting different types and sizes of filter cartridges to facilitate user selection and replacement according to actual needs. Filter cartridge holders are typically made of corrosion-resistant, hygienic materials, such as food-grade plastics or stainless steel, to ensure safety and durability during long-term use.

[0104] In some embodiments, the water treatment equipment 10 further includes a main structure 400, which serves as an installation carrier for mounting the water storage device 100, the temperature control device 200, and the filter element assembly 300. The main structure 400 not only provides robust mechanical support for each functional component but also forms the overall frame of the equipment, ensuring a reasonable layout and secure fixation of each component.

[0105] The main unit structure 400 can internally include a middle frame and a cover plate. The middle frame serves as the internal skeleton, supporting and securing the various functional modules. The middle frame structure is typically made of metal or high-strength engineering plastics to ensure structural rigidity and durability. The middle frame has pre-drilled mounting holes and slots to facilitate precise positioning and secure installation of components such as the water storage device 100, temperature control device 200, and filter element assembly 300. By rationally designing the middle frame structure, space wastage between components can be effectively reduced, achieving a compact internal structure and improving overall space utilization.

[0106] The cover and middle frame are detachably connected, facilitating routine maintenance and component replacement. This connection can be achieved using screws, snap-fit ​​connections, or magnetic attachment, depending on the specific usage environment and maintenance needs. Screw-fixed connections offer a stable structure suitable for applications requiring frequent disassembly and reassembly; snap-fit ​​connections are simple and quick, ideal for user-managed maintenance; and magnetic attachments enhance both ease of installation and removal and overall aesthetics. The detachable cover design allows users or maintenance personnel to easily open the equipment for filter replacement, internal cleaning, or troubleshooting, significantly improving the usability and maintenance efficiency of the water treatment equipment 10.

[0107] In addition, the main structure 400 can also be equipped with a heat insulation layer or sealing strip to enhance the equipment's heat preservation performance and waterproof and dustproof capabilities, further improving the stability and service life of the water treatment equipment 10. The choice of shell material can also vary depending on the application environment, such as using environmentally friendly and durable materials like ABS plastic and polycarbonate, which have good corrosion resistance and mechanical strength, while also meeting the aesthetic requirements of the appearance design.

[0108] It should be noted that the size and shape of the main unit structure 400 can be optimized based on the volume and layout of the internal components. The size can be compact, medium, or large, and can be customized according to the installation environment and user needs. In the compact design, the housing is reduced in size through modular integration, making it easy to install on a desktop or kitchen countertop; the medium design balances performance and space, making it suitable for home and office environments; and the large design is suitable for occasions with high requirements for cooling capacity and water treatment capabilities.
