[0002] In order to meet people's demand for drinking water temperature in daily life, water dispensers are usually equipped with components that can heat or cool drinking water after static circulation. When cooling drinking water, traditional water dispensers use compressors and expansion valves to connect refrigeration pipelines and heat dissipation pipelines to cool drinking water. However, when providing hot water or cold water, a certain heating and cooling time is required, that is, users cannot drink hot water or cold water in time after turning on the heating or cooling switch. The water dispenser needs to spend a certain amount of time to heat or cool. Only when the water dispenser completes heating or cooling, hot water or cold water can be provided for users. It is inconvenient to use and cannot meet users' drinking water needs in time. The heat in the heat dissipation pipeline is usually used to heat drinking water through a heat-conducting structure.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0037] See also Figure 1 , Figure 1 This is a water circuit structure diagram of the first embodiment of the water purification heat exchange device provided in the embodiment of the present application. The present application provides a water purification heat exchange device, which includes a first heat exchange module 10 and / or a second heat exchange module 20, wherein the water circuit a is connected to the water inlet of the first heat exchange module 10, and the water circuit a exchanges heat through the first heat exchange module 10, and / or; the water circuit a is connected to the water inlet of the second heat exchange module 20, and the water circuit a exchanges heat through the second heat exchange module 20.

[0038] For further information, see Figure 2 The water purification heat exchange device of the present application further includes a compressor 30 , and the compressor 30 is connected to the first heat exchange module 10 and the second heat exchange module 20 .

[0039] In an embodiment of the present application, the first heat exchange module 10 is responsible for lowering the temperature of the clean water entering the system, and a refrigerant or other cooling medium may be used. Waterway a is connected to the water inlet of the first heat exchange module 10, and the temperature of the water will decrease after the heat exchange process. The second heat exchange module 20 is responsible for raising the temperature of the clean water after passing through the first heat exchange module, and a heating medium (such as hot water or phase change material) may be used. Waterway a is connected to the water inlet of the second heat exchange module 20, and the temperature of the water will increase after the heat exchange process. The compressor 30 is used to increase the pressure of the refrigerant and promote the heat exchange process. The compressor 30 is connected to the first heat exchange module 10 and the second heat exchange module 20, so that the refrigerant can circulate between the first heat exchange module 10 and the second heat exchange module 20.

[0040] A compressor 30 is a mechanical device that raises low-pressure gas to high pressure. It is widely used in various industrial and household systems to increase the pressure and temperature of the gas. The compressor 30 increases the pressure of the gas by reducing its volume, usually by pistons, rotors or other mechanical parts to do work on the gas in a closed space. In a refrigeration system, the compressor is used to circulate the refrigerant, compressing the refrigerant gas to increase its temperature and pressure, and then transporting it to the condenser for cooling and condensation.

[0041] In some embodiments of this application, please refer to Figure 3 , a first valve assembly 401 and a second valve assembly 402 are arranged on the water circuit a, wherein the first valve assembly 401 is arranged at the first end of the water circuit a, and the second valve assembly 402 is arranged at the second end of the water circuit a, and is arranged between the first heat exchange module 10 and the second heat exchange module 20. The first valve assembly 401 is located at the first end of the water circuit a, and the first end is the starting point of the entire water purification heat exchange device. Therefore, the first valve assembly 401 can be used as a main control valve to control whether the entire water purification heat exchange device is connected to the water flow. The second valve assembly 402 is located at the second end of the water circuit a, between the first heat exchange module 10 and the second heat exchange module 20. It is used to adjust the water flow output after heat exchange by the first heat exchange module 10 and / or adjust the water flow output after heat exchange by the second heat exchange module 20. Of course, it can also be used to adjust the water flow output without heat exchange.

[0042] The first valve assembly 401 and the second valve assembly 402 can be connected to the automatic control system of the system to automatically adjust the opening according to the real-time monitored temperature and flow data. The first valve assembly 401 and the second valve assembly 402 can operate in different working modes, for example, only using the first heat exchange module 10 for cooling, or using the first heat exchange module 10 and the second heat exchange module 20 at the same time for more complex temperature regulation.

[0043] It can be understood that the first valve component can be a single valve, such as a four-way valve, or a combination of multiple valves, such as four one-way valves, etc., and can be specifically set according to actual conditions; similarly, the second valve component can be a single valve, such as a four-way valve, or a combination of multiple valves, such as four one-way valves, etc.

[0044] For example, the first valve component can be a component composed of various types of valves, that is, the first valve component 401 can include one or more of a ball valve, a butterfly valve, a gate valve, a medium valve, a check valve, a regulating valve, a solenoid valve, a diaphragm valve, a safety valve, and a needle valve, wherein: a ball valve controls the flow of a fluid by rotating a ball, and has the characteristics of low flow resistance and fast switching; a butterfly valve: a butterfly valve controls the flow of a fluid by rotating a butterfly plate, and has a simple structure, a small size, and a light weight; a gate valve: a gate valve controls the flow of a fluid by lifting a gate plate, and is suitable for occasions where the pressure is high or the flow needs to be completely cut off; a stop valve: a stop valve controls the flow of a fluid by lifting a valve disc, and is often used when the flow needs to be precisely controlled Check valve: Check valve allows one-way flow of fluid to prevent backflow, and is often used to protect pumps and prevent water hammer effect; Regulating valve: Regulating valve can accurately control the flow of fluid, and is suitable for systems that need to adjust temperature or pressure; Solenoid valve: Solenoid valve controls the opening and closing of the valve through the electromagnetic coil, with fast response speed, and is often used in automatic control systems; Diaphragm valve: Diaphragm valve uses a flexible diaphragm to control the flow of fluid, and is suitable for occasions with high requirements for cleanliness; Safety valve: Safety valve automatically discharges fluid when the pressure exceeds the set value, and is used to protect the system from overpressure damage; Needle valve: Needle valve controls the flow of fluid by rotating the needle valve core, and is often used in laboratories or occasions where small flow rates need to be accurately controlled.

[0045] Optionally, if the system needs to quickly open and close the water channel, a butterfly valve or a ball valve can be used as the first valve component 401; if the system needs to accurately adjust the flow, a regulating valve can be used as the first valve component 401; if the system needs to withstand high pressure, a stop valve or a gate valve can be used as the first valve component; similarly, the second valve component 402 can also be combined as described above, and the specific selection can be made according to actual conditions, which will not be elaborated here.

[0046] It should be noted that a four-way valve is a special type of valve assembly that has four ports and can switch the flow direction of a fluid between two different flow paths. A four-way valve is usually composed of a central body and four connecting ports, and a movable part (such as a slider or a piston) is provided in the central body to control the flow direction of the fluid. A four-way valve can change the flow direction of a fluid, allowing the fluid to switch between two different inlets and two different outlets. In a water purification heating system, a four-way valve can be used to switch the flow direction of hot water and cold water to achieve the adjustment of the mixed water temperature. The four-way valve can be operated manually or automatically controlled by an electric, pneumatic or hydraulic actuator. In an automatic control system, the switching state of a four-way valve is usually controlled by a signal provided by a temperature controller, a pressure controller or other sensors. By switching the flow direction of a four-way valve, energy can be used more efficiently and unnecessary energy waste can be reduced. In addition, a four-way valve is usually designed to be very compact to adapt to application scenarios with limited space. Therefore, the water purification heat exchange device of the present application can be integrated in a water purification device with a smaller volume, such as a water purifier.

[0047] Optionally, in some embodiments of the present application, when preparing cold water, the first valve assembly 401 is used to connect the connection between the water path a and the water inlet of the first heat exchange module 10, and the second valve assembly 402 is used to connect the connection between the water path a and the water outlet of the first heat exchange module 10; when preparing cold water, the first valve assembly 401 is used to connect the connection between the water path a and the water inlet of the second heat exchange module 20, and the second valve assembly 402 is used to connect the connection between the water path a and the water outlet of the second heat exchange module 20; when preparing mixed water, the first valve assembly 401 is used to connect the connection between the water path a and the water inlet of the first heat exchange module 10 and / or the water inlet of the second heat exchange module 2, and the second valve assembly 402 is used to connect the connection between the water path a and the water outlet of the first heat exchange module 10 and / or the water outlet of the second heat exchange module 20.

[0048] When the system needs to prepare cold water, the first valve component 401 conducts water path a with the water inlet of the first heat exchange module 10, so that the water flows into the first heat exchange module 10 for cooling. The second valve component 402 conducts water path a with the water outlet of the first heat exchange module 10, so that the cooled water flows back to the water outlet side of water path a, so that it can be discharged through the faucet or other equipment connected to the water purification heat exchange device; when the system needs to prepare hot water, the first valve component 401 will conduct water path a with the water inlet of the second heat exchange module 20, so that the water flows into the second heat exchange module 20 for heating; the second valve component 402 will conduct water path a with the water outlet of the second heat exchange module 20, so that the heated water flows back to the water outlet side of water path a, so that it can be discharged through the faucet or other equipment connected to the water purification heat exchange device; when warm water or mixed water needs to be prepared, the first valve component 401 can conduct water path a with the water inlets of the first heat exchange module 10 and the second heat exchange module 20 at the same time or separately, and cool and heat as needed. The second valve assembly 402 can simultaneously or separately connect the water circuit a with the water outlets of the first heat exchange module 10 and the second heat exchange module 20, and adjust the temperature of the mixed water as needed. For example, the water source of the water inlet pipe a can be cooled by the first heat exchange module 10, and then the water source of the water inlet pipe a can be heated by the second heat exchange module 20. Finally, according to the actual temperature of the mixed water, the opening and closing of the second valve assembly can be controlled to mix the cold water and the hot water in proportion. In addition, it should be noted that when the user needs normal temperature water, in the embodiment of the present application, the connection between the first valve assembly 401 and the water circuit a and the first heat exchange module 10 and the second heat exchange module 20 is disconnected, and the connection between the first valve assembly 402 and the water circuit a and the first heat exchange module 10 and the second heat exchange module 20 is disconnected, thereby realizing the direct discharge of normal temperature water.

[0049] For example, specifically, a family member needs a glass of ice water. At this time, the system conducts water path a with the water inlet of the first heat exchange module 10 through the first valve component 401, and water flows in and is cooled. The cooled water flows through the water outlet of the first heat exchange module 10 and is conducted back to the water outlet side of water path a through the second valve component 402. Family members turn on the kitchen faucet to get cool drinking water. When family members need hot water to brew hot tea. Through the first valve component 401, the water path a is connected to the water inlet of the second heat exchange module 20, and the water flows in and is heated. The heated water flows through the water outlet of the second heat exchange module 20 and is conducted back to the water outlet side of water path a through the second valve component 402. Family members turn on the faucet to get hot water of suitable temperature for brewing tea. When family members need warm water to prepare breakfast, they can first conduct water through the first valve component 401 to pass through the first heat exchange module 10 for preliminary cooling, and then adjust through the second valve component 402 to allow the water flow to enter the second heat exchange module 20 for heating. According to the required final water temperature, the system accurately controls the degree of opening of the two valve assemblies to achieve a mixture of cold water and hot water. Family members turn on the faucet and get just the right amount of warm water, suitable for direct drinking or preparing breakfast. Of course, the water in waterway a can also be heated first, or the heating and cooling steps can be performed simultaneously, which can be adjusted according to actual conditions. If family members need to use normal temperature water, such as for washing vegetables or fruits, disconnect all connections between the first valve assembly 401 and the second valve assembly 402 and the heat exchange module, so that the water flows directly from the water inlet side to the water outlet side without any heat exchange treatment. Family members turn on the faucet and get normal temperature water without temperature adjustment.

[0050] Optionally, in some embodiments of the present application, please refer to Figure 4 A water pump 50 is also provided on the water channel a. The water pump 50 is provided at the second end of the water channel a, and the water pump 50 pressurizes the water source of the water channel a. The main function of the water pump 50 is to pressurize the water source flowing out of the second end of the water channel a, to ensure that the water source can flow at an appropriate pressure to meet the system's demand for water pressure. It can provide sufficient pressure to overcome resistance in the system, such as pipe friction, local resistance (valves, elbows, etc.) and resistance in the heat exchange module.

[0051] The water pump 60 may be a booster pump, a diaphragm pump or a centrifugal pump. The booster pump is used to increase the water pressure to ensure that the water can pass through a high-precision filtration system such as a reverse osmosis membrane, and is commonly used in reverse osmosis water purifiers in homes or companies. The diaphragm pump is also called a control pump or a metering pump, which is used to control the flow of the water purifier. It is usually used in combination with a booster pump and is suitable for situations where the pressure of household tap water is low. The centrifugal pump relies on the rotation of the impeller to generate centrifugal force to transport liquids.

[0052] Optionally, in some embodiments of the present application, please refer to Figure 5The water purification heat exchange device of the present application may further include a heating module 50, which is connected to at least one of the first heat exchange module 10 and the second heat exchange module 20. Figure 4 As shown, the heating module 50 is connected to the first heat exchange module 10 and the second heat exchange module 20. Specifically, the heating module 50 is arranged at the water outlet of the second heat exchange module 20, and the heating module 50 supplements the heat of the purified water at the water outlet of the second heat exchange module 20.

[0053] The heating module 50 is used to supplement the temperature of the water source in the water channel a, specifically to supplement the water source after heat exchange in the second heat exchange module 20. The clean water first enters the second heat exchange module 20, and the water channel a exchanges heat through the second heat exchange module 20, that is, the heat of the water source in the water channel a is released to increase the temperature of the clean water. After passing through the second heat exchange module 20, the water source will enter the heating module 50. The heating module 50 supplements the heat of the clean water at the outlet of the second heat exchange module 20, which can be done by electric heating, gas heating or other heating methods. As can be seen from the above, the second heat exchange module 20 is responsible for preliminary temperature regulation, such as lowering the initial temperature of the clean water. The heating module 50 is responsible for further adjusting the temperature after the second heat exchange module 20 to ensure that the clean water reaches the required final temperature.

[0054] For example, if the user needs to prepare water at 100°C, the second heat exchange module 20 is responsible for the initial temperature regulation, and transfers heat to the clean water through the heat exchange process (possibly through a heat medium, such as steam, hot water or other heat carriers), thereby increasing the temperature of the clean water, such as to 80°C. After being processed by the second heat exchange module 20, the clean water will flow into the heating module 50, where further temperature regulation is performed. The heating module 50 supplements the heat of the clean water at the outlet of the second heat exchange module 20 to ensure that the clean water can reach the required final temperature. This can be achieved through different heating methods, such as electric heating, gas heating or heating in other energy forms. In this way, the water source can be heated quickly, which improves the efficiency of hot water preparation.

[0055] Optionally, in some embodiments of the present application, the first heat exchange module 10 is used to heat up the water source, the second heat exchange module 20 is used to cool down the water source, and the heating module 50 is connected to the first heat exchange module.

[0056] Optionally, in some embodiments of the present application, when the temperature of the first heat exchange module 10 is lower than a first threshold value, the heating module 50 heats the first heat exchange module 10, and / or the heating module 50 heats the water source in the water inlet and / or outlet of the first heat exchange module 50.

[0057] Optionally, in some embodiments of the present application, when the upper limit of the energy storage temperature of the first heat exchange module 10 is lower than the second threshold, the heating module 50 heats the water source in the water inlet and / or water outlet of the first heat exchange module 10 .

[0058] Optionally, in some embodiments of the present application, when the temperature of the water source in the water outlet of the first heat exchange module 10 is lower than the set water outlet temperature, the heating module 50 heats the water source in the water outlet of the first heat exchange module 10 .

[0059] Optionally, in some embodiments of the present application, the first heat exchange module 10 and the second heat exchange module 20 are both used to heat the water source, the water outlet of the first heat exchange module 10 is connected to the water inlet of the second heat exchange module 20, and the heating module 50 is connected to the first heat exchange module 10, the second heat exchange module 20, the water inlet of the first heat exchange module 10, between the first heat exchange module 10 and the second heat exchange module 20, and / or the water outlet of the second heat exchange module 20.

[0060] See also Figure 6 The first heat exchange module 10 and the second heat exchange module 20 are both used to heat the water source. The water outlet of the first heat exchange module 10 is connected to the water inlet of the second heat exchange module 20. The heating module 50 is connected to the first heat exchange module 10, the second heat exchange module 20, the water inlet of the first heat exchange module 10, between the first heat exchange module 10 and the second heat exchange module 20, and the water outlet of the second heat exchange module 20.

[0061] Optionally, in some embodiments of the present application, Figure 7 As shown, the water purification heat exchange device may further include a reflux water path b, one end of which is connected to the water inlet of the second heat exchange module 20 through the water path a, and the other end of which is connected to the water outlet of the second heat exchange module through the water path a. The heating module is used to guide the water source of the water outlet of the second heat exchange module 20 to the reflux water path b for secondary heating.

[0062] The reflux water circuit b allows a portion of the outlet water passing through the second heat exchange module 20 to flow back to its water inlet, forming a secondary heating cycle. The other end of the reflux water circuit b is connected to the downstream position of the water circuit a, that is, the water outlet of the second heat exchange module 20. The heating module 50 performs preliminary heating or heat supplement on the water source at the water outlet of the second heat exchange module 20. Through the reflux water circuit b, the water source is secondary heated in the second heat exchange module 20, which can more accurately control the final water temperature and improve energy utilization efficiency. The system can also be equipped with a temperature sensor and a controller to monitor the outlet water temperature of the heating module 50 and the second heat exchange module 20, and automatically adjust the reflux ratio and heating amount.

[0063] For example, the user selects the required water temperature on the water dispenser, such as hot water for making tea or coffee. The purified water first passes through the second heat exchange module 20, where the water is heated to a temperature close to the required temperature. The heating module 50 is located at the water outlet of the second heat exchange module 20 to preliminarily heat the water or replenish heat. In order to ensure that the water temperature reaches the precise temperature set by the user, part of the hot water flows back to the water inlet of the second heat exchange module 20 through the return water path b, forming a secondary heating cycle. The built-in temperature sensor monitors the outlet water temperature of the heating module 50 and the second heat exchange module 20 in real time. The controller automatically adjusts the heating intensity of the heating module 50 and the flow rate of the return water path b according to the monitored temperature and the temperature set by the user to achieve precise temperature control. Since the refluxed water already contains a certain amount of heat, secondary heating can use energy more efficiently and reduce heat loss. After secondary heating and precise control, the water output by the water dispenser reaches the precise temperature required by the user to meet the needs of making tea, coffee or other beverages.

[0064] Optionally, in some embodiments of the present application, a first exchange medium and a first energy storage component are provided in the first heat exchange module 10, and the first energy storage component lowers the temperature of the water channel a through the first exchange medium. The second heat exchange module 20 is provided with a second exchange medium and a second energy storage component, and the second energy storage component 20 increases the temperature of the water channel a through the second exchange medium.

[0065] The first energy storage component is responsible for storing cold energy (for example, through a cooling medium or a phase change material). The first exchange medium (for example, water, refrigerant or other fluid) absorbs cold energy in the first energy storage component, and then exchanges heat with the water in water path a to reduce its temperature. The second energy storage component is responsible for storing heat energy (for example, through a heating medium or a phase change material). The second exchange medium absorbs heat energy in the second energy storage component, and then exchanges heat with the water in water path a to increase its temperature.

[0066] The energy storage components can be phase change materials (PCMs), which change state (such as from solid to liquid) when they absorb or release heat, or can be other types of heat storage technologies, such as thermal storage tanks. The heat exchange medium circulates between the energy storage components and the water circuit, absorbing heat from the energy storage components and transferring it to the clean water, or vice versa, absorbing heat from the clean water and storing it in the energy storage components. By using energy storage components, the system can store energy when electricity demand is low or cost is low, thereby reducing energy waste and lowering operating costs.

[0067] It should be noted that a phase changer generally refers to a medium in which a substance can change from one phase (such as solid, liquid or gas) to another phase under certain temperature and pressure conditions. In a heat exchanger, the use of a phase changer can significantly improve the efficiency and effectiveness of heat exchange. The phase changer absorbs or releases a large amount of heat during the phase change process, and this heat is called the latent heat of phase change. This makes the phase changer very effective in the heat exchange process. In a refrigeration system, the phase changer (such as refrigerant) evaporates in the evaporator, absorbs heat, and thus reduces the temperature. In the condenser, the phase changer condenses, releasing heat, thereby heating the surrounding fluid.

[0068] Optionally, in some embodiments of the present application, the first heat exchange medium and the second heat exchange medium are both high thermal conductivity media. High thermal conductivity media have higher thermal conductivity and can transfer heat from the energy storage component to the clean water or from the clean water to the energy storage component more quickly. Among them, the high thermal conductivity medium can be a metal-based composite material, a high thermal conductivity nano-composite dielectric material, a high thermal conductivity polyimide dielectric film, a thermally conductive insulating elastic rubber, and a thermally conductive filler, as follows: Metal-based composite materials: Metal-based composite materials combine the properties of metal materials and inorganic non-metallic materials, such as high thermal conductivity, high strength, low density, and adjustable thermal expansion coefficient; High thermal conductivity nano-composite dielectric materials: These materials improve their thermal conductivity by adding nanofillers, such as carbon nanotubes, graphene, boron nitride nanosheets, etc., which can significantly improve the polymer's Thermal conductivity, used for electronic packaging and thermal management; high thermal conductivity polyimide dielectric film: the thermal conductivity of polyimide (PI) material is improved by adding high thermal conductivity fillers or through specific processing techniques, such as electrospinning; thermally conductive insulating elastic rubber: using silicone rubber substrate, boron nitride, alumina and other ceramic particles as fillers, with good thermal conductivity and high insulation; thermal conductive fillers: such as thermal conductive silicone grease, thermal conductive paste, etc., these materials not only have the effect of thermal conductivity, but can also be used as bonding, sealing and potting materials. The specific selection should be based on the actual situation, which will not be elaborated here.

[0069] Optionally, in some embodiments of the present application, the first heat exchange module 10 is arranged in close contact with the water channel a, and / or the second heat exchange module 20 is arranged in close contact with the water channel a. The close contact arrangement can increase the surface area of ​​the heat exchange module in contact with the water channel a, reduce the distance between the heat exchange medium and the purified water, and the close contact arrangement helps to transfer heat faster while saving space, which is beneficial to application scenarios with limited space, such as integrating the water purification heat exchange device of the present application into a smaller water purification device.

[0070] The above is the water purification heat exchange device provided in this application.

[0071] As can be seen from the above, the present application provides a water purification heat exchange device, including a first heat exchange module 10, a water circuit is connected to the water inlet of the first heat exchange module 10, and the water circuit a exchanges heat through the first heat exchange module 10; a second heat exchange module 20, a water circuit a is connected to the water inlet of the second heat exchange module 20, and the water circuit exchanges heat through the second heat exchange module. The compressor is connected to the first heat exchange module 10 and the second heat exchange module 20. The heat exchange water purification solution provided by the present application is provided with a first heat exchange module 10 and a second heat exchange module 20. When the user does not need to use water, the heat generated by the system is heated or cooled by the first heat exchange module 10 and the second heat exchange module. When the user uses water, the heat stored in the first heat exchange module 10 and the second heat exchange module 20 is used to heat or cool the water in the water outlet pipeline, thereby achieving the effect of immediately outputting hot water or cold water.

[0072] The present application also provides a water dispenser (not shown), which includes a water purification heat exchange device. The specific structure of the water purification heat exchange device refers to the above-mentioned embodiment. Since the water dispenser proposed in the present application adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
