[0001] This application relates to the field of water treatment equipment technology, and in particular to a water treatment device. Background Technology
[0002] Traditional water purification equipment typically integrates the cooling unit directly onto the cold water tank, achieving refrigeration by cooling the water within. This design is relatively simple and facilitates integrated water storage and cooling. However, because the cooling unit acts directly on the water tank, the cooling efficiency is affected by factors such as the large water volume and limited heat exchange area, resulting in unsatisfactory overall cooling performance and difficulty in meeting the demands for rapid cooling and low-temperature maintenance. Furthermore, the continuous input of room-temperature water causes the temperature of the cold water in the tank to rise, affecting the stability and effectiveness of the chilled water, thereby reducing the overall performance of the equipment.

[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] Traditional water purification equipment typically integrates the cooling unit directly onto the cold water tank, achieving refrigeration by cooling the water within. This design is relatively simple and facilitates integrated water storage and cooling. However, because the cooling unit acts directly on the water tank, the cooling efficiency is affected by factors such as the large water volume and limited heat exchange area, resulting in unsatisfactory overall cooling performance and difficulty in meeting the demands for rapid cooling and low-temperature maintenance. Furthermore, the continuous input of room-temperature water causes the temperature of the cold water in the tank to rise, affecting the stability and effectiveness of the chilled water, thereby reducing the overall performance of the equipment.
[0031] 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 water storage device 100 includes a water storage tank 110 and a temperature control box 120, the temperature control box 120 is connected to the water storage tank 110 through a pipe and is used to transport cold water into the water storage tank 110; or, the temperature control box 120 and the water storage tank 110 are at least partially nested and connected; the temperature control device 200 is at least partially thermally coupled to the temperature control box 120, and the temperature control device 200 is used to cool the water in the temperature control box 120.
[0032] The water treatment equipment 10 of this embodiment significantly improves the efficiency of cold water preparation by thermally coupling the temperature control device 200 to the temperature control tank 120 and connecting it to the water storage tank 110 via a pipeline. Specifically, when preparing cold water, the temperature control device 200 can first cool the water in the temperature control tank 120, thereby ensuring that the water reaches a lower temperature before being transported to the water storage tank 110. This design effectively avoids the interference of continuous input of room temperature water on the temperature of the cold water in the water storage device 100, ensuring the temperature stability of the cold water in the water storage tank 110.
[0033] In addition, the water treatment equipment 10 of this embodiment adopts a separate structure of water storage device 100 and temperature control device 200, which optimizes the efficiency of heat exchange. Compared with the traditional method of directly cooling water storage tank 110, it can reach the required low temperature more quickly and improve the cooling efficiency.
[0034] To improve the cooling efficiency of the temperature control device 200, in some embodiments, the capacity of the water tank 110 can be designed to be larger than the capacity of the temperature control box 120. The rationale for this design is mainly reflected in the following aspects:
[0035] First, the temperature control tank 120, as the core area for cooling the cold water, has a small volume, which significantly reduces the heat capacity of the water, allowing the temperature control device 200 to cool the water more quickly, thus improving cooling speed and efficiency. Specifically, the capacity of the water storage tank 110 can be designed to be 1.5 times, 2 times, or even 3 times or more the capacity of the temperature control tank 120. The specific value can be flexibly determined according to actual usage requirements and equipment size, and is not limited here.
[0036] Secondly, the temperature control device 200 is cooled by a thermally coupled temperature control box 120. The temperature control box 120 is connected to the water storage tank 110 via a pipeline to achieve continuous supply and replenishment of cold water. Since the water in the temperature control box 120 has been pre-cooled rapidly, the water temperature in the larger water storage tank 110 can be maintained at a low level after being supplied, avoiding the problems of low cooling efficiency and temperature fluctuation caused by directly cooling a large-capacity water storage tank in traditional designs.
[0037] Furthermore, the large capacity of the water tank 110 helps to store and buffer cold water, ensuring that users can still obtain a stable supply of low-temperature cold water during peak water usage periods. It also reduces the immediate load on the temperature control device 200, extending the equipment's service life. To further ensure water temperature stability, the pipes connecting the temperature control box 120 and the water tank 110 can be covered with insulation material to reduce heat loss and improve cold water delivery efficiency.
[0038] In summary, by designing the water storage tank 110 to have a larger capacity than the temperature control box 120, the cooling performance of the temperature control device 200 can be fully utilized, achieving rapid cooling and efficient temperature maintenance, and significantly improving the overall cooling efficiency and user experience of the water treatment equipment 10.
[0039] In one embodiment, the water treatment device 10 further includes a filter element assembly 300, which is used to install external filter elements. These filter elements include, but are not limited to, various types such as reverse osmosis (RO) membrane filters, activated carbon filters, ceramic filters, and ultrafiltration (UF) membrane filters to meet different water purification needs. The filter element assembly 300 effectively removes impurities, heavy metals, organic matter, and microorganisms from the water, ensuring that the water entering the temperature control tank 120 is high-quality filtered water, thereby guaranteeing the safety and hygiene of drinking water.
[0040] The output end of the filter element assembly 300 is connected to the temperature control chamber 120 via a pipe. The pipe can be made of food-grade stainless steel, food-grade plastic, or other corrosion-resistant and safe materials to ensure that the filtered water is not subject to secondary contamination during transportation. Simultaneously, the pipe can be equipped with an insulation layer to reduce water temperature fluctuations and maintain the temperature stability of the water when it enters the temperature control chamber 120.
[0041] After the filtered water is delivered to the temperature control chamber 120, the temperature control device 200 cools the filtered water to a preset temperature, making it suitable for direct consumption. This design not only simplifies the water purification and cooling process but also achieves efficient integration of water purification and cooling, avoiding the water quality and temperature control problems caused by traditional equipment that requires cooling before filtration or separates filtration and cooling.
[0042] Furthermore, the filter element assembly 300 can be designed as a detachable structure, facilitating filter element replacement and cleaning by users or maintenance personnel. Specifically, the filter element assembly 300 can be connected using various methods such as snap-fit, threaded connection, or quick-release interface to adapt to different installation environments and maintenance needs. The advantage of using a detachable structure is improved equipment maintenance convenience and service life, ensuring the continued effectiveness of the filter element's function.
[0043] The filter cartridge assembly 300 can also be configured with multiple filter cartridges arranged in parallel or series, allowing for the selection of different filter cartridge combinations based on actual water purification needs. For example, larger particulate impurities can be removed first through mechanical filtration, followed by deep purification through an RO membrane filter, and finally, an activated carbon filter can be used to improve the taste and remove odors. The combination of multiple filter cartridges significantly enhances the comprehensiveness and filtration efficiency of water purification, meeting the personalized needs of different users.
[0044] In one embodiment, the water treatment equipment 10 further includes a housing structure 400, which serves as the mounting carrier for the filter element assembly 300, the water storage device 100, and the temperature control device 200, thus fixing and protecting the components. The housing structure 400 not only enables a reasonable layout and compact installation of the functional modules but also effectively prevents the external environment from affecting the internal components, such as dust, moisture, and mechanical impact, thereby ensuring the safety and stability of the equipment.
[0045] The housing structure 400 can be made of metal materials such as stainless steel or aluminum alloy, or high-strength engineering plastics such as ABS or polycarbonate. The metal housing structure 400 has good mechanical strength and corrosion resistance, making it suitable for applications with high requirements for equipment structure; while the plastic material has the advantages of being lightweight, easy to mold, and low in cost, making it suitable for applications that require portability and economy.
[0046] The housing structure 400 internally incorporates mounting brackets, slots, or guide rails to secure the water tank 110, temperature control box 120, and filter element assembly 300. This ensures the components maintain stable positions during operation, preventing loosening or damage due to vibration or movement. Installation can employ various methods, including screw connections, snap-fit structures, and slide rail fittings. In practice, screw connections offer high fixing strength, suitable for long-term use; snap-fit structures facilitate disassembly and assembly, making maintenance and filter element replacement easier; and slide rail fittings promote modular design and rapid assembly.
[0047] Specifically, the temperature control chamber 120 is partially or entirely located inside the water storage tank 110; and / or, the temperature control chamber 120 is at least partially attached to the outside of the water storage tank 110. This structural design facilitates tight thermal coupling between the temperature control chamber 120 and the water storage tank 110, thereby improving the overall heat exchange efficiency. Through partial attachment, the temperature control chamber 120 can directly cool the outer wall of the water storage tank 110, ensuring a continuous cooling effect for the cold water inside the water storage tank 110, reducing the rate of temperature rise of the cold water, and improving the temperature stability and user experience of the cold water.
[0048] Furthermore, the temperature control box 120 not only functions in cooling its own internal water, but also effectively absorbs the cold energy leaking from the storage tank 110. Due to usage or heat conduction, the cold water in the storage tank 110 will generate some heat that leaks outwards. The temperature control box 120, by being designed to be close to the storage tank 110, can recover this leaked cold energy, avoiding energy waste and further improving the overall cooling efficiency and energy-saving effect of the system.
[0049] When room temperature water enters the temperature control chamber 120, the chamber acts as a buffer, first cooling the incoming water to prevent it from directly entering the storage tank 110 and causing temperature fluctuations. This design effectively avoids the problem of unstable temperature in the cold water tank due to continuous input of room temperature water in traditional systems, ensuring that the temperature of the cold water in the storage tank 110 remains within the set low temperature range, meeting the requirements for rapid cooling and continuous low temperature maintenance.
[0050] In practice, the temperature control box 120 can be attached using various methods such as bonding, clamping, or mechanical fastening. Bonding methods, such as using a thermally conductive adhesive, ensure efficient heat transfer while avoiding mechanical stress concentration. Clamping structures facilitate disassembly and maintenance, making them suitable for applications requiring frequent maintenance. Mechanical fastening methods, such as screw fixing, provide high stability and are suitable for environments with significant equipment vibration.
[0051] When the temperature control chamber 120 is entirely located inside the water storage tank 110, it functions as an internal heat exchanger. It can employ tubular, plate, or spiral heat exchange structures to increase the heat exchange area and improve heat transfer efficiency. This design makes the cooling process of the water in the water storage tank 110 by the temperature control device 200 more concentrated and efficient, while reducing thermal resistance and increasing the cooling speed. The flow velocity and water circulation method within the temperature control chamber 120 can also be optimized according to actual needs, such as using a forced circulation pump to drive the water flow, improving heat exchange efficiency and temperature uniformity.
[0052] In one embodiment, the temperature control chamber 120 is arranged around the water storage tank 110, which further enhances the thermal coupling effect between the temperature control chamber 120 and the water storage tank 110. Through this surrounding arrangement, the temperature control chamber 120 can cover more of the surface area of the water storage tank 110, significantly improving its ability to absorb leaked cold energy from the water storage tank 110, thereby effectively reducing cold energy loss and improving the cold insulation effect of the water storage tank 110.
[0053] Specifically, when the temperature control chamber 120 surrounds the water storage tank 110, it forms a wraparound cooling structure, increasing the contact area between the temperature control chamber 120 and the water storage tank 110, thus increasing the heat exchange area. This allows the cooling capacity transferred from the temperature control chamber 120 to the water storage tank 110 more evenly and fully. This structure not only improves cooling efficiency but also buffers the influence of the external ambient temperature on the internal cold water temperature of the water storage tank 110, maintaining water temperature stability.
[0054] Furthermore, the temperature control box 120 surrounds the water storage tank 110, forming a multi-faceted cold energy conduction path. This effectively absorbs the cold energy lost from the water storage tank 110 in all directions, avoiding energy waste caused by cold energy loss in one direction. This not only optimizes the energy efficiency ratio of the refrigeration system but also extends the cold water retention time, improving the user experience.
[0055] In practical implementation, the temperature control box 120 can surround the water tank 110 in a completely enclosed or partially enclosed manner. The specific surrounding area can be flexibly designed according to the equipment volume, cooling requirements, and structural layout. For example, the surrounding area can be 50%, 70%, 80%, or even higher of the outer surface area of the water tank 110. A larger surrounding area significantly improves the cooling effect, but the equipment volume and manufacturing cost increase accordingly; a smaller surrounding area reduces costs, but weakens the cooling effect. The specific design should be based on a trade-off between the actual application scenario and economic considerations, and no single limitation is made here.
[0056] The implementation of the surrounding structure can be varied, including an integral molding design, a segmented assembly structure, or a modular combination. Materials can be selected from metals with excellent thermal conductivity (such as aluminum alloys or stainless steel) or plastics with optimized thermal conductivity. Thermally conductive adhesives or pads can be used to further enhance the heat transfer efficiency between the temperature control chamber 120 and the water storage tank 110.
[0057] In one embodiment, the water storage tank 110 is at least partially located inside the temperature control chamber 120. By placing the water storage tank 110 inside the temperature control chamber 120, direct heat conduction cooling between the water storage tank 110 and the temperature control chamber 120 can be achieved, thereby improving the overall cooling efficiency. Specifically, the cold water or refrigerant inside the temperature control chamber 120 is in close contact with the water storage tank 110, and the cooling energy can be efficiently and quickly transferred to the water in the water storage tank 110, achieving effective cooling and cold preservation of the water in the water storage tank 110.
[0058] This embedded structural design offers significant technical advantages. First, because the water tank 110 is enclosed within the temperature control box 120, the heat exchange area between the two is greatly increased, reducing cold loss and accelerating the cooling speed. This allows the water in the water tank 110 to be cooled to the predetermined temperature in a short time, meeting the user's demand for rapid cold water supply. Second, the embedded structure makes the combination of the water tank 110 and the temperature control box 120 more compact, saving overall equipment volume and making it suitable for space-constrained installation environments, thus improving the equipment's space utilization rate.
[0059] Furthermore, the fact that the water storage tank 110 is partially located inside the temperature control chamber 120 can effectively reduce the impact of ambient temperature on the cold water temperature inside the water storage tank 110. As the core area of refrigeration, the temperature control chamber 120 can form a stable low-temperature environment barrier, preventing external heat from penetrating into the water storage tank 110, maintaining the stability and durability of the cold water temperature, and improving the user experience.
[0060] In practice, the water tank 110 can be installed inside the temperature control chamber 120 in various ways, such as suspended, embedded, or supported by a fixed bracket. The material of the water tank 110 should have good thermal conductivity and corrosion resistance, such as food-grade stainless steel or high thermal conductivity plastic, to ensure cooling effect and water quality safety. The temperature control chamber 120 can be equipped with circulating coolant or refrigerant, which continuously removes the heat generated by the water tank 110 through an internal circulation system, enhancing cooling performance.
[0061] In one embodiment, the outer wall of the water storage tank 110 is attached to the temperature control box 120, and the water storage tank 110 is located at the bottom of the temperature control box 120. This design utilizes the physical property of the higher density of cold water, so that the heavier cold water after cooling can preferentially settle into the water storage tank 110, thereby achieving effective control and stable maintenance of the water temperature in the water storage tank 110.
[0062] Specifically, the water in the temperature control chamber 120, after being refrigerated, has a lower temperature and a higher density. Under the influence of gravity, this cold water naturally flows downwards, preferentially entering the storage tank 110 at the bottom. Meanwhile, room temperature water, with its lower density, enters the storage tank 110 less frequently, remaining or flowing more in the upper part of the temperature control chamber 120. This natural stratification based on differences in water density allows cold water to be concentrated in the storage tank 110, ensuring that the water temperature in the storage tank 110 remains within the set low-temperature range and preventing room temperature water from directly mixing into the storage tank 110 and causing a temperature rise.
[0063] This design not only improves water temperature stability but also achieves efficient energy utilization. Cold water preferentially enters the storage tank 110, concentrating the cooling energy for the water within the tank and reducing energy waste. Simultaneously, the compact structure of the storage tank 110, located at the bottom of the temperature control chamber 120, shortens the cold water flow path, reduces energy loss during heat transfer, and improves the overall efficiency of the refrigeration system.
[0064] Furthermore, the close fit between the outer wall of the water tank 110 and the temperature control box 120 enhances heat transfer between them. A larger contact area results in higher heat exchange efficiency, thus accelerating the cooling rate of the water in the water tank 110 and improving overall cooling performance. The specific contact area can be designed to be 30%, 50%, or 70% of the outer wall area of the water tank 110, etc. A larger contact area can further improve cooling efficiency but may increase manufacturing difficulty and cost; a smaller contact area helps reduce manufacturing complexity and cost, but the cooling effect is relatively weaker. The specific design should be considered comprehensively based on actual design requirements and cost budget, and no single limitation is set here.
[0065] To ensure a proper fit, the connection between the water tank 110 and the temperature control box 120 can be achieved using various methods, such as thermally conductive adhesive, thermally conductive pads, or mechanical fasteners (e.g., screws, clips). Thermally conductive adhesive and pads effectively fill the tiny gaps between the two, improving heat transfer efficiency while reducing stress concentration caused by mechanical connections; mechanical fasteners ensure structural stability, are suitable for vibration environments, and facilitate maintenance. The specific connection method can be flexibly selected based on the equipment's operating environment and maintenance requirements.
[0066] In one embodiment, the water storage device 100 further includes a connecting pipe connected to the water storage tank 110 and used for transporting water. The connecting pipe is at least partially inserted inside the temperature control box 120. By placing the connecting pipe inside the temperature control box 120, the cold water stored in the temperature control box 120 can be used to effectively cool the connecting pipe.
[0067] Specifically, when the connecting pipe passes through the temperature control box 120, the low-temperature environment inside the box directly surrounds the pipe, ensuring it maintains a low temperature during transport. This prevents the water temperature from rising due to exposure to higher ambient temperatures, reducing heat transfer and loss, and further guaranteeing the cooling effect of the transported water. This design effectively extends the range of cold energy retention, ensuring not only the low temperature of the water in the storage tank 110 but also maintaining a stable temperature within the connecting pipe, reducing heat backflow and energy waste.
[0068] Furthermore, the connecting pipes are installed inside the temperature control box 120, which contributes to the compact design of the overall structure, reduces the heat dissipation area and cold loss of external pipes, and improves the energy efficiency ratio of the equipment. The connecting pipes are cooled by cold water inside the temperature control box 120, which enables effective temperature control during the transportation of cold water from the water storage tank 110 to other parts of the equipment, avoiding the impact of temperature fluctuations on subsequent use and improving the stability and performance of the overall system.
[0069] In practice, the materials for connecting pipes can be selected from those with low thermal conductivity and low temperature resistance, such as polyethylene (PE), polyvinyl chloride (PVC), and stainless steel, to adapt to the low temperature environment inside the temperature control box 120°C, while ensuring water quality safety and pipe durability.
[0070] The number of connecting pipes running through the temperature control box 120 can be adjusted according to system design requirements; the specific number can be one, two, or more, and there is no single limitation. Multiple connecting pipes can be installed to achieve cooling transport of multiple water sources, adapting to the needs of complex systems. Furthermore, by rationally arranging the pipe positions and routes, the distribution of cooling capacity and heat exchange efficiency can be further optimized.
[0071] In one embodiment, the connecting pipes include an inlet pipe and an outlet pipe. The inlet pipe is connected to the water storage tank 110 and the temperature control box 120 respectively, and is used to transport water to the water storage tank 110. The outlet pipe is connected to the output end of the water storage tank 110, and the outlet pipe is at least partially inserted into the temperature control box 120.
[0072] Firstly, when the inlet pipe connects to the temperature control tank 120 and the storage tank 110, the room temperature water entering the temperature control tank 120 through the inlet pipe undergoes preliminary cooling within the tank, thus preventing room temperature water from directly entering the storage tank 110 and causing temperature fluctuations in the storage tank 110. This design creates a buffer cooling zone, ensuring a relatively stable water temperature entering the storage tank 110, improving the uniformity and continuity of the cold water temperature within the storage tank 110, and effectively meeting the needs of rapid cooling and constant temperature control.
[0073] Secondly, the outlet pipe is connected to the output end of the water storage tank 110 and is at least partially installed inside the temperature control box 120. The low-temperature environment of the temperature control box 120 is used to keep the cold water flowing in the outlet pipe cool. Specifically, when the outlet pipe is installed inside the temperature control box 120, it reduces the temperature rise of the cold water in the water storage tank 110 due to heat conduction during transportation, preventing the cold water temperature from rising again and ensuring that the water delivered to the user remains at a low temperature, thus improving the user experience and overall system performance.
[0074] The inlet and outlet water pipes are installed inside the temperature control box 120, which can effectively reduce heat exchange between the exposed parts of the pipes and the environment, reduce energy loss, and further improve the energy efficiency ratio of the refrigeration system. By extending the cooling transfer path, the system not only ensures the stability of the water temperature in the storage tank 110, but also ensures the continuity and stability of the water temperature during pipeline transportation.
[0075] Specifically, the number of inlet and outlet pipes can be flexibly set according to system design requirements, and can be one, two, or more. When multiple pipes are used, independent cooling and transportation of multiple water bodies can be achieved, adapting to complex water circuit layouts and multi-user needs, and improving the system's applicability and flexibility.
[0076] To further improve the heat transfer efficiency between the pipes and the temperature control chamber 120, the contact surfaces between the pipes and the interior of the temperature control chamber 120 can be tightly connected using thermally conductive adhesive, thermally conductive pads, or fastening mechanical parts to avoid thermal resistance caused by gaps and ensure efficient transfer of cold energy. Fasteners can be screws, clips, or elastic clamps, ensuring a secure connection while facilitating maintenance and disassembly.
[0077] Furthermore, the water storage device 100 also includes heat exchange fins 130. One end of the heat exchange fins 130 is connected to the temperature control box 120, and the other end of the heat exchange fins 130 extends into the water storage tank 110. The heat exchange fins 130 are used for heat exchange with the water in the water storage tank 110. By setting the heat exchange fins 130 to exchange heat between the water storage tank 110 and the temperature control box 120, the cooling effect of the water storage tank 110 can be effectively improved.
[0078] Specifically, the heat exchange fins 130 serve as the heat transfer medium, transferring the low-temperature environment inside the temperature control chamber 120 to the water inside the water tank 110 through one end. Since the heat exchange fins 130 are directly installed inside the water tank 110, their contact area with the water inside the water tank 110 is greatly increased, enabling them to quickly and efficiently transfer cooling energy to the water inside the water tank 110, significantly improving heat transfer efficiency and shortening cooling time.
[0079] The heat exchange fins 130 are preferably made of metals with good thermal conductivity, such as aluminum alloy, stainless steel, or copper, which have a high thermal conductivity coefficient to ensure rapid transfer of cold energy. At the same time, these materials have good corrosion resistance and mechanical strength, making them suitable for use in aquatic environments and ensuring long-term stable operation of the equipment. The heat exchange fins 130 can be in the shape of plates, fins, or tubes.
[0080] The connection between one end of the heat exchange fin 130 and the temperature control box 120 can be achieved through welding, bonding, or mechanical fastening. Welding provides good heat conduction and structural stability; bonding allows for the use of thermally conductive adhesive, reducing thermal resistance and facilitating assembly; mechanical fastening, such as clips or screws, facilitates maintenance and replacement. When the other end of the heat exchange fin 130 is inserted into the water tank 110, it should be in close contact with the water to prevent the formation of an air insulation layer and further improve heat exchange efficiency.
[0081] The direct heat exchange path achieved through the heat exchange fins 130 can effectively compensate for the inadequacy of heat conduction through the outer walls of the water storage tank 110 and the temperature control box 120, enhance the transfer of cold energy to the water in the water storage tank 110, reduce temperature gradient and heat loss, and improve the cold insulation performance and energy efficiency of the entire water storage device 100.
[0082] Furthermore, the number of heat exchange fins 130 can be adjusted according to heat exchange requirements. The specific number can be one, two, or more. Reasonably arranging multiple heat exchange fins 130 can expand the heat exchange area, evenly distribute the cooling capacity, avoid insufficient local cooling, and improve the temperature uniformity of the water in the water tank 110 and the system stability. No single limit is imposed here.
[0083] Furthermore, the water storage device 100 also includes an insulation layer, which covers the outside of the water storage tank 110 and / or the temperature control box 120. By providing the insulation layer, the heat exchange between the water storage tank 110 and the temperature control box 120 and the external environment can be effectively reduced, thereby significantly improving the cooling effect of the water storage device 100.
[0084] Specifically, the insulation layer, acting as a thermal resistance layer, prevents heat from the external environment from entering the water storage tank 110 and the temperature control tank 120 through conduction, convection, and radiation, thereby reducing cold loss and extending the cooling time of the cold water. When the insulation layer covers the outside of the water storage tank 110, it directly isolates the water storage tank 110 from the outside environment, maintaining a stable water temperature inside the water storage tank 110. When it covers the outside of the temperature control tank 120, it further reduces the heat exchange between the cold water inside the temperature control tank 120 and the external environment, reducing heat loss at the source and improving the overall energy efficiency of the refrigeration system.
[0085] The insulation layer can be made of materials with low thermal conductivity and excellent insulation performance, such as polyurethane foam, polystyrene foam, rubber and plastic materials, glass wool, and rock wool. These materials have good thermal insulation properties, effectively preventing heat transfer under large temperature differences, and are also lightweight, durable, moisture-proof, and corrosion-resistant, making them suitable for long-term stable use. The insulation layer can be applied as a whole, in sections, or with specific areas covered. A complete overlay minimizes heat transfer and is suitable for applications requiring high cold insulation performance; sectioned or partial overlays allow for targeted insulation enhancement in areas with significant heat loss, balancing cost-effectiveness and performance to meet different practical needs.
[0086] Furthermore, the way the insulation layer is bonded to the water tank 110 and the temperature control box 120 also affects the insulation performance. Methods such as adhesives, mechanical clamping, or a covering sleeve structure can be used to ensure the insulation layer adheres tightly to the equipment surface, preventing air gaps that could lead to thermal bridging and weaken the insulation effect. Adhesives and mechanical clamping ensure the stable fixation of the insulation layer, preventing it from falling off or shifting during use and extending its lifespan.
[0087] Furthermore, the water storage device 100 also includes a first cold water pump, which is connected to the water storage tank 110 and the temperature control tank 120 respectively and is used to transport cold water; and / or the water storage device 100 also includes a second cold water pump, which is connected to the water storage tank 110 and / or the temperature control tank 120 and is used to output cold water.
[0088] The first chilled water pump enables efficient delivery of chilled water from the temperature control tank 120 to the storage tank 110. Specifically, the first chilled water pump pumps the chilled water, which has undergone refrigeration treatment, from the temperature control tank 120 into the storage tank 110, ensuring that the water in the storage tank 110 continuously receives sufficient cooling, thereby maintaining a stable and low-temperature water temperature in the storage tank 110. This design overcomes the problems of insufficient chilled water supply or uneven temperature that may result from relying solely on natural convection and heat conduction, and improves the active control capability of the chilled water circulation. At the same time, the pumping method shortens the chilled water delivery time, reduces cooling loss, and improves the overall system's cooling efficiency and response speed.
[0089] The second cold water pump is connected to the water storage tank 110 and is mainly used to pump cold water from the tank for drinking or daily use. By installing the second cold water pump, the output flow rate and pressure of the cold water can be actively controlled, ensuring a stable and sufficient supply of cold water for users. This pumping method avoids inconvenience caused by insufficient water pressure and prevents the cold water from overheating due to prolonged stagnation, thus improving user experience and water quality safety.
[0090] The first and second cold water pumps can be set up independently or used together to form a closed-loop cold water circulation system and a cold water output system, which synergistically improve the overall performance of the water storage device 100. The first cold water pump is responsible for the circulation and replenishment of cold water and the maintenance of temperature, while the second cold water pump is responsible for the external output of cold water. The two work together to ensure the continuity and stability of the cold water supply and meet the cold water needs of different usage scenarios.
[0091] Furthermore, chilled water pumps can be driven in various ways, including electric drive, frequency converter control, or brushless DC motors. Frequency converter control can intelligently adjust the pump speed according to actual temperature and flow requirements, achieving energy saving and noise control; brushless DC motors offer advantages such as high efficiency, low noise, and long lifespan, making them suitable for both domestic and commercial environments. The pump body and impeller materials should possess good corrosion and wear resistance, such as stainless steel or engineering plastics, to ensure long-term stable operation of the equipment.
[0092] In one embodiment, the second cold water pump can not only be connected to the water tank 110 to output cold water, but can also be configured to drive the temperature control box 120 to output cold water. This design is particularly suitable for applications requiring rapid cold water output.
[0093] Specifically, the temperature control tank 120, due to its small size, boasts a rapid cooling speed and high cooling capacity response efficiency, enabling it to quickly cool water to the set temperature. Therefore, when users have a high degree of immediacy in their demand for chilled water, directly outputting chilled water from the temperature control tank 120 via the second chilled water pump can significantly shorten the response time of the chilled water supply and improve efficiency. Furthermore, the chilled water in the temperature control tank 120 undergoes rapid cooling treatment, resulting in a low temperature; direct output ensures a consistently low chilled water temperature, enhancing the user experience. Compared to outputting chilled water from the storage tank 110, the rapid cooling function of the temperature control tank 120 can meet the demand for large quantities of chilled water in a short period, making it particularly suitable for peak periods or situations requiring urgent chilled water supply.
[0094] In one embodiment, the temperature control device 200 includes a heat exchanger 210 and a hot water tank 220. The working end of the heat exchanger 210 is thermally coupled to the temperature control tank 120, and the hot water tank 220 is connected to the heat exchanger 210 and used to supply hot water. The working end of the heat exchanger 210 can cool the temperature control tank 120, thereby achieving effective regulation of the water temperature inside the water storage device 100.
[0095] The heat exchanger 210 operates based on the thermoelectric effect or the refrigeration cycle principle. Specifically, the heat exchanger 210 can be a thermoelectric cooler or a compressor cooler, each with its own advantages. The thermoelectric cooler is characterized by its small size, high efficiency, and fast response, making it suitable for small devices and applications with strict space requirements; while the compressor cooler is suitable for applications requiring large-scale cooling, providing stronger cooling capacity and more stable operating performance. By appropriately selecting the type of heat exchanger 210, the cooling effect and system efficiency can be optimized according to actual needs.
[0096] The heat exchanger 210 exchanges heat with the heat exchanger tank 220 via a heat exchanger source. Specifically, the heat exchanger tank 220, as the heat exchange medium, carries away the heat released from the heat exchanger 210's heat exchanger end, preventing heat accumulation within the system and thus improving overall thermal management efficiency. Connected to the heat exchanger 210, the heat exchanger tank 220 effectively absorbs heat from the heat exchanger end and carries it away through circulating water, ensuring a stable low-temperature environment within the temperature control box 120. The structural design of the heat exchanger tank 220 should consider fluid dynamics characteristics to optimize water flow velocity and heat exchange efficiency, ensuring the system maintains good heat dissipation performance even under high load conditions.
[0097] The connection between the heat exchanger 210 and the hot water tank 220 can take various forms, such as flange connection, threaded connection, or quick coupling. The specific connection method should be selected based on ease of installation, sealing performance, and ease of maintenance. Flange connections are suitable for applications requiring high strength and stability, while quick couplings facilitate disassembly and maintenance, making them suitable for environments requiring frequent inspection and repair.
