Description

Technical Field

[0001] This utility model relates to the field of water supply device technology, and in particular to a water supply device. Background Technology

[0002] In daily life, water supply systems are crucial for providing domestic hot water, and their performance is of great concern. Traditional water supply systems have significant limitations in temperature control. From a working principle perspective, most traditional water supply systems rely on simple temperature control devices for temperature regulation, often only capable of basic temperature settings and rudimentary monitoring feedback. For example, mechanical thermostats sense water temperature changes based on the principle of thermal expansion and contraction, but their accuracy is relatively low, making it difficult to accurately detect and respond promptly to subtle fluctuations in water temperature.

[0003] In terms of hardware construction, the heating and water circuit systems of traditional water supply devices lack sophisticated design considerations. Heating power is typically fixed or has only a few adjustable levels, making it difficult to accurately match the actual heat supply required to maintain a stable water temperature under different water usage scenarios. Furthermore, the layout and pipe diameter of the water circuits do not adequately consider the impact of water flow velocity and pressure changes on water temperature, easily leading to fluctuating water temperatures due to uneven mixing with cold water or changes in water flow patterns during the outflow process.

[0004] Furthermore, the control systems of traditional water supply devices are not intelligent enough, lacking a complete temperature feedback and real-time adjustment mechanism. They cannot obtain accurate water temperature data in real time, and therefore cannot quickly and flexibly adjust the heating power or water flow control according to the actual water temperature. Consequently, they cannot effectively cope with complex operating conditions such as multiple water points being used simultaneously or sudden changes in water flow. Ultimately, this results in unstable hot water output temperature, making it difficult to meet users' needs for comfortable and stable water temperature. Utility Model Content

[0050] 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.

[0051] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a water supply device 1 provided in an embodiment of this application. The water supply device 1 includes: a water inlet module 10, a temperature control module (including a heating module 20 and a cooling module 40 mentioned below), a water outlet module 30, a drainage module 50, and a control module 60.

[0052] The water inlet module 10 is connected to the water outlet module 30 and the temperature control module, and is used to control the amount of water entering the water supply device 1;

[0053] The temperature control module is connected to the water outlet module 30 and is used to adjust the temperature of the water entering the temperature control module;

[0054] The water outlet module 30 is connected to the drainage module 50 and is used to output water that meets the preset temperature.

[0055] The drainage module 50 is connected to the temperature control module and is used to discharge the wastewater from the temperature control module and the water outlet module 30.

[0056] The control module 60 is connected to the water inlet module 10, the temperature control module, the water outlet module 30, and the drainage module 50, and is used to control the operation of the water inlet module 10, the temperature control module, the water outlet module 30, and the drainage module 50.

[0057] It should be noted that, since the flow rate requirements for hot water and the flow-infeed circuit are relatively low, in order to save space and material costs while meeting functional requirements, relatively small diameter pipes, such as 2-point pipes, can be used for hot water and the flow-infeed circuit. The usage of ambient and cold water circuits may be relatively large, and relatively large diameter pipes, such as 3-point pipes, can be used for ambient and cold water circuits. This application does not impose any restrictions on this.

[0058] In one possible implementation, such as Figure 1 As shown, the temperature control module includes a heating module 20 and / or a cooling module 40;

[0059] The heating module 20 is connected to the cooling module 40 and the water outlet module 30, and is used to heat the water entering the heating module 20 through the heat exchange unit, and to store the heat exchange medium for heating.

[0060] The refrigeration module 40 is connected to the water outlet module 30 and is used to refrigerate the water entering the refrigeration module 40.

[0061] In this embodiment, the water inlet module 10 controls the water flow into the water supply device 1, and the heating module 20 heats and stores the water entering the heating module. Then, the water outlet module 30 outputs water at a preset temperature. The drainage module 50 assists in the water return between the water outlet module 30, the heating module 20, and the cooling module 40, and discharges wastewater from the heating module 20, the water outlet module 30, and the cooling module 40. Furthermore, the control module 60 controls the operation of the water inlet module 10, the heating module 20, the water outlet module 30, the cooling module 40, and the drainage module 50 to achieve stable heating of the water entering the water supply device 1 and to effectively implement temperature feedback and real-time adjustment mechanisms, thereby achieving a more stable supply of water at a preset temperature.

[0062] Please see Figure 2 As shown, Figure 2 This is a schematic diagram of the water circuit structure of a drainage module 50 provided in an embodiment of this application. The drainage module 50 includes a first control valve, a wastewater pump 52, and a drainage component 53, wherein the drainage component 53 is connected to the wastewater pump 52 and the first control valve.

[0063] The first control valve is used to control the wastewater flowing from the water outlet module 30 to the drainage component 53; to control the wastewater pump 52 to transfer wastewater from the heating module 20 to the drainage component 53; and to control the wastewater pump 52 to transfer wastewater from the cooling module 40 to the drainage component 53.

[0064] The wastewater pump 52 is used to transfer wastewater from the heating module 20 and / or the cooling module 40 to the drainage component 53.

[0065] The drainage component 53 is used to discharge wastewater from the heating module 20 and / or the cooling module 40, and also to discharge wastewater from the water outlet module 30.

[0066] The drainage component 53 can be a component that discharges water (such as wastewater). The drainage component 53 can be a drainage pipe, a drainage valve, a drainage outlet, or a specific drainage container; this application does not impose any limitations on this. The aforementioned components work together to ensure the effective treatment of wastewater in the water supply system.

[0067] In one possible implementation, such as Figure 2 As shown, the first control valve can be a three-way valve 51 (referred to as the first three-way valve 51). The first water interface of the first three-way valve 51 is connected to the water outlet module 30 through a water path. The second water interface of the first three-way valve 51 is connected to the heating module 10 and the cooling module 40 through a water path. The third water interface of the first three-way valve 51 is connected to the wastewater pump 52 through a water path.

[0068] The first three-way valve 51 can distribute water flow in three different directions, and can switch or mix water flows between different water path branches. The first three-way valve 51 can not only regulate the water flow path, but also work in conjunction with other modules. For example, when the water temperature does not meet the preset temperature, the first three-way valve 51 can change the water flow path to guide the substandard water to the wastewater pump 52 connected to it, thus preparing for subsequent reheating of this water.

[0069] The drainage module 30 is also used to return hot water from the outlet module 30. Specifically, this can be achieved by using the first three-way valve 51 to return water that does not meet the preset temperature and reheat it. When the water temperature is not up to standard, the outlet module 30, through the first three-way valve 51, redirects water that was originally intended to flow out of the outlet module 30 but was not hot enough back towards the heating module 20, allowing this water to return to the heating module 20 for reheating. This ensures that the final output water temperature meets the standard, thus guaranteeing that the user can use water at a suitable temperature. Optionally, if the outlet module 30 detects water that is too hot, it redirects this water back towards the cooling module 40 through the first three-way valve 51, allowing this water to return to the cooling module 40 for cooling, ensuring that the final output water temperature meets the standard, thus guaranteeing that the user can use water at a suitable temperature. The recirculation of water in the cooling module is similar to that in the heating module, and will not be elaborated further here.

[0070] In one possible implementation, please refer to Figure 3 As shown, Figure 3This is a schematic diagram of the water circuit structure of another drainage module 50 provided in an embodiment of this application. The drainage module 50 includes a second control valve, a wastewater pump 52, and a drainage component 53. The second control valve is a one-way valve 54 (such as referred to as a first one-way valve 54). The first water circuit interface of the first one-way valve 54 is connected to the water outlet module 30 through a water circuit. The second water circuit interface of the first one-way valve 54 is connected to the heating module 20, the cooling module 40, and the wastewater pump 52 through a water circuit. The wastewater pump 52 is connected to the drainage component 53.

[0071] The first one-way valve 54 can be used to control the flow of wastewater from the outlet module 30 to the drain component 53. The wastewater may include excess water generated during the reheating process when the water temperature does not meet the preset temperature, as well as impurities generated during system operation and water discharged during maintenance. Discharging this wastewater from the system through the wastewater drain outlet 43 maintains the cleanliness of the entire water system, prevents the accumulation of impurities from adversely affecting the normal operation of the system and water quality, and extends the system's service life.

[0072] Please see Figure 4 As shown, Figure 4 This is a schematic diagram of the water circuit structure of a heating module 20 provided in an embodiment of this application. The heating module 20 includes a heat exchange unit 21, a heating energy storage unit 22, and an instant heating unit 23. The heat exchange unit 21 is connected to the water inlet module 10 and the instant heating unit 23. The instant heating unit 23 is connected to the water outlet module 30 and the heating energy storage unit 22. The heating energy storage unit 22 is connected to the cooling module 40.

[0073] Heat exchange unit 21 is used to heat the water entering the heating module 20;

[0074] The heating energy storage unit 22 is used to store the water that enters the heating energy storage unit 22;

[0075] The instant heating unit 23 is used to heat the water entering the heating energy storage unit 22 and / or heat the water output from the heat exchange unit 21.

[0076] The cooling module 40 is also used to replenish water to the heating energy storage unit 22.

[0077] The heat exchange unit 21 can be a device that transfers heat from one fluid to another through heat conduction, convection, and radiation. The larger the heat transfer area of ​​the heat exchange module, the more heat can be transferred under the same conditions, resulting in higher heating efficiency. In the solution provided in this application, the heat transfer area of ​​the heat exchange module can be designed to be large enough to achieve more efficient heat transfer to the fluid.

[0078] Understandably, compared with direct heating methods (such as electric heating, flame heating, etc.), heat exchange unit 21 has a higher energy utilization rate. For example, heat exchange unit 21 can use industrial waste heat and residual heat for heating, which can greatly improve energy utilization and reduce energy waste. Heat exchange unit 21 has precise temperature control, such as by adjusting parameters such as fluid flow rate and temperature to achieve precise temperature control. Heat exchange unit 21 has high safety. Compared with flame heating and other methods, heat exchange unit 21 has no open flame and has a greater safety advantage.

[0079] The medium in the heating energy storage unit 22 can be water or oil, and this application makes no limitation thereto. The heating energy storage unit 22 can be a heat tank, which is a tank with heat storage function, capable of storing heated water to meet the user's demand for hot water within a certain period of time, playing a role in buffering and continuously supplying hot water. The heat tank can also have a built-in heater for heating the medium inside the heat tank.

[0080] The instant heating unit 23 can be used to quickly heat water. By combining the instant heating unit 23 with the heat storage function of the heating energy storage unit 22, water at a preset temperature can be provided rapidly, improving supply efficiency.

[0081] In one possible implementation, the heating module 20 further includes a circulating water pump 25, which is connected to the heating energy storage unit 22 and the heat exchange module 21.

[0082] The circulating water pump 25 is used to transport the water stored in the heating energy storage unit 22 to the heat exchange unit 21, and then return to the heating energy storage unit 22 after flowing through the heat exchange unit 21.

[0083] In one possible implementation, the heating module 20 further includes a three-way valve 26 (such as referred to as a second three-way valve 26). The first end of the second three-way valve 26 is connected to the circulating water pump 25, the second end of the second three-way valve 26 is connected to the heat exchange unit 21, and the third end of the second three-way valve 26 is connected to the instant heating unit 23.

[0084] The second three-way valve 26 provides multiple water flow path options. When a user needs hot water quickly, the second three-way valve 26 can be controlled to direct water to the instant heating unit 23, which can quickly heat the water to meet the user's immediate hot water needs. When the water supply device 1 is in an energy-saving or preheating mode, the second three-way valve 26 can direct water to the heat exchange unit 21. The heat exchange unit 21 can achieve temperature increase by exchanging heat with other media (such as preheated water or other heat sources) to provide hot water more energy-efficiently.

[0085] Please see Figure 5 As shown, Figure 5 This is a schematic diagram of the water circuit structure of another heating module 20 provided in an embodiment of this application. The heating module 20 further includes an exhaust unit 24, which is connected to the heating energy storage unit 22.

[0086] The exhaust unit 24 is used to exhaust the heating and energy storage unit 22.

[0087] It should be noted that the exhaust unit 24 may include an exhaust pipe, which can be a pipe with a larger diameter, such as a 3-point pipe. During the operation of the water system, gas may be generated, and the 3-point pipe can better exhaust these gases, preventing gas accumulation from causing adverse effects on the system, such as abnormal pressure.

[0088] In one possible implementation, please refer to Figure 6 As shown, Figure 6 This is a schematic diagram of air replenishment through the water outlet component 301 of the water outlet module 30 provided in this application embodiment. The first end of the exhaust unit 24 is connected to the heating energy storage unit 22, and the second end of the exhaust unit 24 is connected to the water outlet component 301 of the water outlet module 30. The exhaust unit 24 is also used to replenish air to the wastewater pump 52 (related pipeline) in the drainage module 50 through the water outlet component 301. Specifically, the exhaust unit 24 is also used to replenish air to the related pipeline or container in the following situations: when the wastewater pump 52 drains wastewater from the water outlet module 30, when the wastewater pump 52 drains wastewater from the cooling module 40, and when the wastewater pump 52 drains wastewater from the heating energy storage unit 22.

[0089] The water outlet component 301 can be a component that provides water (to the user). This water outlet component 301 can be a faucet, showerhead, spray nozzle, or water spout, etc. Taking a faucet as an example, air can be introduced through the faucet's vent to replenish the drainage power component (i.e., wastewater pump 52), and this application does not impose any limitations on this. When the wastewater pump 52 drains wastewater from the water outlet module 30, the refrigeration module 40, and the heating energy storage unit 22, the drainage process causes changes in the pressure within the pipeline. Replenishing air prevents negative pressure from occurring during the drainage process. By replenishing air, the pressure within the pipeline can be kept relatively stable, ensuring that the wastewater pump 52 can operate continuously and stably, and helping to improve the drainage efficiency of the wastewater pump 52.

[0090] In one possible implementation, please refer to Figure 7 As shown, Figure 7This is a schematic diagram illustrating air replenishment through the vent 302 of the water outlet module 30, as provided in this embodiment of the application. The exhaust unit 24 is also used to replenish air to the wastewater pump 52 in the drainage module 50 when draining wastewater from the water outlet module 30, through the vent 302 of the water outlet module 30; to replenish air to the wastewater pump 52 in the drainage module 50 when draining wastewater from the cooling module 40, and to replenish air to the wastewater pump 52 in the drainage module 50 when draining wastewater from the heating energy storage unit 22, through the vent 302 of the drainage module 50.

[0091] The vent 302 of the water outlet module 30 allows air to be supplied to the wastewater pump 52 during drainage. Specifically, when the wastewater pump is pumping water, air must be supplied to the water path to ensure normal water flow. A one-way valve can be installed at the vent 302 to evacuate the water from the pipeline. Optionally, this vent 302 and one-way valve configuration can be achieved using a compressible water bladder.

[0092] In one possible implementation, please refer to Figure 8 As shown, Figure 8 This is a schematic diagram of the water circuit structure of a water outlet module 30 provided in an embodiment of this application. The water outlet module 30 includes a two-way valve 31 (referred to as the first two-way valve 31), a negative temperature coefficient (NTC) thermistor 32, a one-way valve 33 (referred to as the second one-way valve 33), and a water outlet 34. The first end of the first two-way valve 31 is connected to the instant heating unit 23 and the water inlet module 10, and the second end of the first two-way valve 31 is connected to the drainage module 50 and the first end of the NTC thermistor 32. The first end of the NTC thermistor 32 is connected to the cooling module 40. The second end of the NTC thermistor 32 is connected to the first end of the second one-way valve 33, and the second end of the second one-way valve 33 is connected to the water outlet 34.

[0093] NTC thermistor 32 is used to measure the temperature of the water being transported.

[0094] Outlet 34 is used to output water that meets the preset temperature.

[0095] It should be noted that the water outlet module 30 can perform precise water temperature detection for further water temperature screening and water flow diversion. Through the above-mentioned strict temperature screening mechanism, the entire water supply system can always provide users with stable water that meets the temperature requirements, which not only improves user satisfaction but also enhances the overall practicality of the system.

[0096] Optionally, the diversion function of the water outlet module 30 also contributes to the stable operation of the system. By draining water with unqualified temperature to the drainage module 50, the system can take corresponding measures according to the specific situation, such as reheating the water with unqualified temperature, or checking whether the instant heating unit 23, heat exchange unit 21 and heating energy storage unit 22 are faulty, thereby ensuring the continuous and stable operation of the entire system.

[0097] Optionally, the exhaust unit 24 is connected to the water outlet 34 to discharge the gas generated during the operation of the water system through the water outlet 34, thereby avoiding the accumulation of gas and its adverse effects on the system.

[0098] Understandably, the first two-way valve 31 can be used to deliver water from the instant heating unit 23 to the NTC thermistor 32; optionally, the first two-way valve 31 can also be used to deliver water from the water inlet module 10 to the drain module 50. Optionally, the NTC thermistor 32 can be used to detect water temperature and deliver water that meets the preset water temperature to the outlet, and deliver water that does not meet the preset water temperature to the drain module 50 through the first two-way valve 31.

[0099] In one possible implementation, the second one-way valve 33 is used to control the discharge of the first type of liquid from the water outlet module and to prevent the second type of liquid from entering from the outside.

[0100] The first type of liquid can be any liquid required by the water supply system, such as sterilizing water for sterilization or high-temperature water for high-temperature rinsing. The second type of liquid can be any liquid not required by the external water supply system, such as coffee or milk; this application does not impose any restrictions on this.

[0101] The second check valve 33 can be used to control the direction of water flow, ensuring that water flows only in a specific direction. Its pressure can be assessed to determine whether it functions properly under different pressure conditions, thereby preventing backflow and ensuring the normal operation of the water system. In this embodiment, the second check valve 33 can prevent sterilizing water from being discharged from the faucet and prevent external liquids (such as coffee) from being drawn back into the water system, thus maintaining the cleanliness of the water system and preventing contamination. This application does not impose any limitations on this aspect.

[0102] As the heated water flows towards the outlet 34, the NTC thermistor 32 installed in the internal water circuit monitors the water temperature in real time. The resistance of this NTC thermistor 32 is negatively correlated with temperature; that is, the resistance decreases as the temperature rises and increases as the temperature falls. When the water temperature reaches the set acceptable temperature, the resistance of the NTC thermistor 32 is within the normal range. At this time, the control module 60 keeps the wastewater circuit of the drainage module 50 closed to supply water at the required temperature to the user.

[0103] The precise temperature control mechanism described above ensures that the output water always meets the temperature requirements, preventing issues caused by sudden temperature fluctuations. Furthermore, it avoids the wasteful discharge of water that is not at the correct temperature. Recirculating substandard water for reheating, rather than reheating all the water, helps save energy and improves the energy efficiency of the water supply system.

[0104] Please see Figure 9 As shown, Figure 9 This is a schematic diagram of the water circuit structure of a water inlet module 10 provided in an embodiment of this application. The water inlet module 10 includes an inlet 11, a flow meter unit 12, and a flow control unit 13. The inlet 11 is connected to the flow meter unit 12 and the flow control unit 13. The flow control unit 13 is connected to the outlet module 30 and the cooling module 40.

[0105] The flow meter unit 12 is used to measure the water flow rate to the heating module 20;

[0106] The flow control unit 13 is used to control the flow rate of water entering the water outlet module 30, the heating module 20, and the cooling module 40.

[0107] It should be noted that inlet 11 is the entrance for water into the water supply system and the starting point of the entire water circulation. External water sources can enter the water supply system through inlet 11. Flow meter unit 12 can be used to measure the flow rate of water entering heat exchange unit 21. By measuring the flow rate of water entering heat exchange unit 21, the system can better control the heating process. For example, the heating power can be adjusted according to the flow rate to ensure that the water is heated sufficiently and efficiently; if the flow rate is high, the heating power may need to be increased; if the flow rate is low, the heating power can be appropriately reduced to avoid energy waste.

[0108] The flow control unit 13 can control the flow rate of water entering the water outlet module 10 and the cooling module 40, so as to better control the water flow rate according to demand (such as the user's requirements for hot water output, system safety restrictions, etc.). At the same time, the flow control unit 13 can also distribute water to different branches. For example, when heating is not required, some water can be directly distributed to the water outlet module as output, or when cold water and hot water need to be mixed to adjust the water temperature, the corresponding distribution operation can be performed. This application does not limit this.

[0109] In one possible implementation, such as Figure 9As shown, the flow control unit 13 includes a flow control valve 131 and an on / off valve 132. The first end of the flow control valve 131 is connected to the water inlet 11, the second end of the flow control valve 131 is connected to the first end of the on / off valve 132, and the second end of the on / off valve 132 is connected to the water outlet module 30.

[0110] It should be noted that this application uses the combination of flow control valve 131 and on / off valve 132 as an example for illustration, and does not limit the scope of this application. When the system is in standby mode or under certain conditions where water flow is not required, on / off valve 132 is closed to prevent unnecessary water flow in the pipeline, thereby reducing heat loss and water waste. When water is needed, on / off valve 132 is opened, and flow control valve 131 can accurately control the flow rate, avoiding excessive water consumption due to excessive flow, thus achieving energy saving.

[0111] The on / off valve 132 and the flow control valve 131, when used together, can also prevent water hammer to a certain extent. Water hammer is a pressure wave generated by a sudden change in water flow (such as a sudden valve closure), which may damage pipelines and equipment. When it is necessary to quickly stop the water flow, first close the flow control valve 131, gradually reduce the flow rate, and then close the on / off valve 132. This can effectively reduce water hammer, extend the service life of equipment and pipelines, and improve system safety.

[0112] Optionally, in the above embodiments, only the flow control valve 131 may be used to precisely regulate the water flow rate, thereby avoiding water waste or problems such as excessive water temperature drop due to excessive flow. Optionally, in the above embodiments, only the on / off valve 132 may be used to control the opening and closing of the water circuit, thereby achieving simple and quick control of the water circuit. This application does not impose any limitations on this.

[0113] In one possible implementation, such as Figure 9 As shown, the flow meter unit 12 includes a flow meter 121. The first end of the flow meter 121 is connected to the inlet 11, and the second end of the flow meter 121 is connected to the heat exchange unit 21.

[0114] Flow meter 121 measures the water flow rate entering the system, helping the system determine the initial water intake situation. If the water flow rate does not meet expectations, it can indicate that the system may have a blockage in the inlet pipe, insufficient water pressure, or other problems. Through the measurement of flow meter 121, the system can perform preliminary troubleshooting during the startup phase to ensure normal operation thereafter.

[0115] Optionally, the data provided by the flow meter 121 can help the system make decisions regarding water flow distribution. Furthermore, the data from the flow meter 121 can work in conjunction with other components (such as the flow control valve 131 and the NTC thermistor). For example, when the flow meter 121 detects a large inlet water flow and the NTC thermistor detects a slightly low water temperature, the system can control the flow control valve 131 to appropriately increase the inlet water flow while adjusting the heating power to quickly raise the water temperature, thereby achieving precise water supply.

[0116] Please see Figure 10 As shown, Figure 10 This is a schematic diagram of the water circuit structure of a refrigeration module 40 provided in an embodiment of this application. The refrigeration module 40 includes a refrigeration unit 41 and a cold water pump 42. The inlet of the refrigeration unit 41 is connected to the second end of the on / off valve 132, and the outlet of the refrigeration unit 41 is connected to the outlet module 30 through the cold water pump 42.

[0117] The refrigeration unit 41 is used to refrigerate the water entering the refrigeration module 40;

[0118] The chilled water pump 42 is used to output the cooled water / or the water that has entered the refrigeration module 40 to the water outlet module 30.

[0119] It should be noted that the refrigeration unit 41 can cool the water entering the refrigeration module 40. For example, when a user needs cold water, water flows into the refrigeration unit 41 from the second end of the on / off valve 132. The refrigeration unit 41 can lower the water temperature through its own refrigeration mechanism (such as compressor refrigeration, semiconductor refrigeration, etc.) to meet the user's need for cold water.

[0120] The chilled water pump 42 serves as the power transmission unit in the refrigeration module 40, delivering chilled water to the outlet water module 30. Optionally, when refrigeration is not required, the chilled water pump 42 can also directly deliver water entering the refrigeration module 40 to the outlet water module 30. For example, when the equipment is in energy-saving mode or the user only needs room temperature water, the chilled water pump 42 can simply deliver untreated water. This ensures the normal circulation and supply of water throughout the equipment's water system, allowing the equipment to flexibly meet the different water temperature requirements of various users.

[0121] In one possible implementation, the refrigeration module 40 further includes a one-way valve 43 (such as referred to as a third one-way valve 43), the first end of which is connected to the cold water pump 42, and the second end of which is connected to the water outlet module 30.

[0122] The third check valve 43 ensures that water flows from the chilled water pump 42 to the outlet module 30, but prevents water from flowing back from the outlet module 30 to the chilled water pump 42. The third check valve 43 prevents backflow to protect the chilled water pump 42 and the refrigeration unit 41 in the refrigeration module 40. Backflow of water could create reverse pressure on the chilled water pump 42, causing the impeller of the chilled water pump 42 to reverse, potentially damaging the motor and mechanical components of the chilled water pump 42. The third check valve 43 also helps stabilize the water pressure and flow in the outlet module 30. By limiting the reverse flow of water, it ensures that the water received by the outlet module 30 is supplied according to the normal flow direction and pressure designed for the equipment.

[0123] In one possible implementation, the refrigeration module 40 further includes a one-way valve 44 (such as referred to as a fourth one-way valve 44), the first end of which is connected to the refrigeration unit 41, and the second end of which is connected to the exhaust unit 24 of the heating module 20.

[0124] The fourth one-way valve 44 prevents hot water from flowing back from the exhaust unit 24 of the heating module 20 into the refrigeration unit 41. During operation, the heating module 20 may generate high-temperature water or steam, which is then exhausted through the exhaust unit 24. When the pressure on the heating module 20 side is higher than that on the refrigeration unit 41 side (e.g., during heating), hot water or steam may enter the refrigeration unit 41 through the pipes, potentially damaging it. The entry of high-temperature water or steam may disrupt its internal refrigeration structure, such as damaging refrigeration pipes or affecting the performance of the refrigerant.

[0125] In one possible implementation, the refrigeration module 40 further includes a two-way valve 45 (such as referred to as a second two-way valve 45), the first end of which is connected to the refrigeration unit 41, and the second end of which is connected to the on / off valve 132 of the water inlet module 10.

[0126] When the water level in the refrigeration unit 41 is detected to be low or when a new water source needs to be added, the second two-way valve 45 can open the passage from the on / off valve 132 to the refrigeration unit 41, so that water can be smoothly added to the refrigeration unit 41 to ensure that the refrigeration unit 41 always has enough water for refrigeration and maintains the normal refrigeration function of the equipment.

[0127] When the sterilization program is started, the second two-way valve 45 can introduce water containing sterilizing ingredients (such as water that has been treated with ultraviolet light, water with added disinfectant, etc.) from the on / off valve 132 of the water inlet module 10 into the refrigeration unit 41. This application does not limit this.

[0128] In one possible implementation, please refer to Figure 11 As shown, Figure 11 This is a schematic diagram of the water circuit structure of another refrigeration module 40 provided in an embodiment of this application. The refrigeration module 40 also includes a three-way valve 46 (such as referred to as the third three-way valve 46), the first end of which is connected to the refrigeration unit 41, the second end of which is connected to the heating energy storage unit 22 and the heat exchange unit 21 of the heating module 20, and the third end of which is connected to the first three-way valve 51 of the drainage module 50.

[0129] The third three-way valve 46 can be used to achieve diverse water flow directions, making the water supply system of the water supply device 1 more flexible and efficient.

[0130] In one possible implementation, such as Figure 11 As shown, the heating module 20 also includes a water pump 27, the first end of which is connected to the instant heating unit 23, and the second end of which is connected to the heating energy storage unit 22.

[0131] The water pump 27 is mainly responsible for transporting water between the instant heating unit 23 and the heating energy storage unit 22 within the heating module 20. After the instant heating unit 23 rapidly heats the water, the water pump 27 can transport the heated water to the heating energy storage unit 22 for storage, which helps maintain the water circulation inside the heating module 20 for later use.

[0132] The water supply device 1 provided in this application can precisely adjust the water temperature. It can achieve precise temperature control and provide multiple water temperature options through various control valves and NTC thermistors. In terms of energy utilization, it is highly efficient and energy-saving. Through the collaboration of heat storage tanks, heat exchangers and thick film instant heating units, it can achieve rapid heating, heat storage and heat recovery and reuse. The system has high reliability. Multiple one-way valves can prevent backflow contamination, ensure water hygiene and safety and maintain stable pressure balance, and improve the overall user experience and equipment operating efficiency.

In practical applications, the above functions can be assigned to different functional units and modules as needed, that is, the internal structure of the device can be divided into different functional units or modules to complete all or part of the functions described above.
