[0046] 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.

[0047] 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 heating module 20, a water outlet module 30, and a control module 40.

[0048] The water inlet module 10 is connected to the heating module 20 and the water outlet module 30, and is used to control the amount of water entering the water supply device;

[0049] The heating module 10 is connected to the water outlet module 30 and is used to heat the water entering the heating module 20 and to store the heated water.

[0050] The water outlet module 30 is used to output water that meets the preset temperature;

[0051] The control module 40 is electrically connected to the water inlet module 10, the heating module 20 and the water outlet module 30, and is used to control the operation of the water inlet module 10, the heating module 20 and the water outlet module 30.

[0052] 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.

[0053] In this embodiment, the water inlet module 10 controls the water flow into the water supply system, the heating module 20 heats the water and stores the heated water, the water outlet module 30 detects the water temperature and outputs water at the preset temperature, and the control module 40 controls the operation of the water inlet module 10, the heating module 20 and the water outlet module 30 to achieve stable heating of the water entering the water supply system and to effectively implement temperature feedback and real-time adjustment mechanisms, thereby achieving a more stable supply of water at the preset temperature.

[0054] Please see Figure 2 As shown, Figure 2 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 heating energy storage unit 21 and an instant heating unit 22. The water inlet module 10 is connected to the heating energy storage unit 21, the heating energy storage unit 21 is connected to the instant heating unit 22, and the instant heating unit 22 is connected to the water outlet module 30. The heating energy storage unit 21 includes a heating unit 211 and a heat storage unit 212.

[0055] Heating unit 211 is used to heat the water entering heating energy storage unit 21;

[0056] The thermal storage unit 212 is used to store the water that enters the heating energy storage unit 21;

[0057] The instant heating unit 22 is used to heat the water output from the heating energy storage unit 21 and / or the water output from the water inlet module.

[0058] In one possible implementation, heating unit 211 is used to perform a first heating treatment on the water entering the heating energy storage unit 21; that is, heating unit 22 can be used to perform a second heating treatment on the water output from the heating energy storage unit 21.

[0059] It should be noted that the medium of the heating unit 211 can be water or oil, and this application does not limit this. The heating energy storage unit 21 can be a hot water tank, which is a tank with heating and heat storage functions. It can heat water and store a certain amount of hot water to meet the user's demand for water at a preset temperature within a certain period of time, playing a role in buffering and continuously supplying water at the preset temperature. The instant heating unit 22 can be used to rapidly heat water. By combining the instant heating unit 22 with the heat storage function of the heating energy storage unit 21, water at the preset temperature can be provided rapidly when needed, improving the efficiency of the supply.

[0060] In one possible implementation, the heating unit 22 can be used to heat the heating energy storage unit 21 during idle periods.

[0061] It should be noted that "off-peak hours" can refer to periods when the system is not in high demand for water, such as at night. The instant heating unit 22 can rapidly convert electrical energy into heat energy through electric heating. During off-peak hours, it can transfer heat to the heating energy storage unit 21, raising the water temperature within the unit and storing the heat. Heating during off-peak hours can take advantage of off-peak electricity prices (if applicable) to reduce energy costs. Compared to continuous high-load operation during peak electricity consumption periods, off-peak heating allows for a more even distribution of the workload on the instant heating unit 22, helping to reduce the frequency of start-ups and shutdowns, thereby reducing equipment wear and tear and extending its lifespan.

[0062] Please see Figure 3 As shown, Figure 3 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 a gas release unit 23, which is connected to the heating energy storage unit 21 and the water outlet module 30.

[0063] The gas release unit 23 is used to exhaust gas from the heating module 20 through the vent of the water outlet module 30.

[0064] It should be noted that the gas release unit 23 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 discharge these gases, avoiding gas accumulation that may have adverse effects on the system, such as abnormal pressure.

[0065] Please see Figure 4 As shown, Figure 4 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 a water inlet 11, a flow meter unit 12, and a flow control unit 13. The water inlet 11 is connected to the flow meter unit 12 and the flow control unit 13. The flow meter unit 12 is connected to the heating module 20, and the flow control unit 13 is connected to the water outlet module 30.

[0066] Flow meter unit 12 is used to measure the water flow rate towards heating module 20;

[0067] The flow control unit 13 is used to control the flow rate of water entering the water outlet module and the heating module.

[0068] 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 input to heating module 20. By measuring the water flow rate entering heating module 20, 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.

[0069] The flow control unit 13 can be used to control and distribute the water flow in the water supply system, so as to control the water flow according to demand (such as the user's requirement 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, a portion of the water can be directly distributed to the outlet module 30 as output, or when cold water and hot water need to be mixed to adjust the water temperature, the application does not limit this.

[0070] Please see Figure 5 As shown, Figure 5 This is a schematic diagram of the water circuit structure of a flow control unit 13 provided in an embodiment of this application. 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 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 outlet module 30.

[0071] 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.

[0072] 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 suddenly closing a valve), 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.

[0073] 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.

[0074] Please see Figure 6 As shown, Figure 6 This is a schematic diagram of the water circuit structure of a flow meter unit 12 provided in an embodiment of this application. The flow meter unit 12 includes a first bidirectional valve 121 and a flow meter 122. The first end of the first bidirectional valve 121 is connected to the water inlet 11, and the second end of the first bidirectional valve 121 is connected to the flow meter 122.

[0075] It should be noted that two-way valves (such as the first two-way valve 121 mentioned above and the second two-way valve to be mentioned below) can control the flow of water in both directions, providing a more flexible water flow control method. Two-way valves play an important role in some complex water circulation systems or situations where the direction of water flow needs to be changed.

[0076] Flow meter 122 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 122, the system can perform preliminary troubleshooting during the startup phase to ensure normal operation thereafter.

[0077] Optionally, the data provided by the flow meter 122 can help the system make decisions regarding water flow distribution. Furthermore, the data from the flow meter 122 can work in conjunction with other components (such as the flow control valve 131, the NTC thermistor, etc.). For example, when the flow meter 122 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 water flow into the heating module 20, while simultaneously adjusting the heating power to quickly raise the water temperature, thereby achieving precise water supply.

[0078] Please see Figure 7 As shown, Figure 7 This is a schematic diagram of another water supply device 1 provided in an embodiment of this application. The water supply device 1 also includes a drainage module 50, which is connected to the water outlet module 30 and the heating module 20. It is used to assist the water flow back of the heating module 20 and to discharge the wastewater from the heating module 20 and the water outlet module 30.

[0079] Please see Figure 8 As shown, Figure 8This 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 control valve 501, a drainage power component 502, and a drainage component 503, wherein the drainage component 503 is connected to the drainage power component 502 and the control valve 501.

[0080] The control valve 501 is used to control the flow of wastewater from the outlet module 30 to the drainage component 503;

[0081] The drainage power unit 502 is used to transfer wastewater from the heating module 20 to the drainage unit 503;

[0082] The drainage component 503 is used to drain the wastewater from the heating module 20 and the wastewater from the water outlet module 30.

[0083] The drainage power component 502 can be a component that provides power for the wastewater discharge process or the water return process. This drainage power component 502 can be a wastewater pump or a compressible air bladder; this application makes no limitation in this regard. The drainage component 503 can be a component that discharges water (such as wastewater). The drainage component 503 can be a drainage pipe, a drainage valve, or a drainage outlet, or a specific drainage container; this application makes no limitation in this regard. The above-mentioned components work together to ensure the effective treatment of wastewater in the water supply system.

[0084] In one possible implementation, please refer to Figure 9 As shown, Figure 9 This is a schematic diagram illustrating air replenishment through the vent 301 of the water outlet module 30, as provided in an embodiment of this application. The gas release unit 23 is also used to replenish air to the drainage power component 502 in the drainage module 50 through the vent 301 of the water outlet module 30 when draining wastewater from the water outlet module 30.

[0085] The water outlet module 30 can supply air to the water supply and drainage power components through the air vent 301. Specifically, a one-way valve can be installed at the air vent 301 to evacuate the water from the pipeline. This configuration of the air vent 301 and the one-way valve can be achieved using a compressible water bladder.

[0086] In one possible implementation, please refer to Figure 10 As shown, Figure 10 This is a schematic diagram illustrating air replenishment via the water outlet component 302 of the water outlet module 30, as provided in an embodiment of this application. The gas release unit 23 is also used to replenish air to the drainage power component 502 in the drainage module 50 via the water outlet component 302 of the water outlet module 30 when draining wastewater from the water outlet module 30.

[0087] The water outlet component 302 can be a component that provides water (to the user). This water outlet component 302 can be a faucet, showerhead, spray nozzle, or water spout, etc. Taking a faucet as an example, the faucet's vent can be used to replenish air to the drainage power component; this application does not limit this. When the drainage power component 502 drains wastewater from the water outlet module 30, the drainage process causes changes in the pressure within the pipeline. Replenishing air prevents negative pressure from occurring during drainage. By replenishing air, the pressure within the pipeline can be kept relatively stable, ensuring that the drainage power component 502 can operate continuously and stably, and helping to improve the drainage efficiency of the drainage power component 502.

[0088] Please see Figure 11 As shown, Figure 11 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 temperature detection unit 31 and a water outlet 32. The temperature detection unit 31 is connected to the second end of the on / off valve 132 and the water outlet 32.

[0089] Temperature detection unit 31 is used to detect water temperature and output water at a preset temperature to the outlet.

[0090] Outlet 32 ​​is used to output water at a preset temperature.

[0091] It should be noted that the temperature detection unit 31 can perform accurate 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 practicality of the entire system.

[0092] Optionally, the diversion function of the temperature detection unit 31 also contributes to the stable operation of the system. By draining water that is not at the required temperature to the drainage module 50, the system can take appropriate measures according to the specific situation, such as reheating the water that is not at the required temperature or checking whether the heating module 20 is malfunctioning, thereby ensuring the continuous and stable operation of the entire system.

[0093] Please see Figure 12 As shown, Figure 12This is a schematic diagram of the water circuit structure of a temperature detection unit 31 provided in an embodiment of this application. The temperature detection unit 31 includes a second bidirectional valve 311, a negative temperature coefficient NTC thermistor 312, and a one-way valve 313. The first end of the second bidirectional valve 311 is connected to the heating module 20 and the water inlet module 10, and the second end of the second bidirectional valve 311 is connected to the drainage module 50 and the first end of the NTC thermistor 312. The second end of the NTC thermistor 312 is connected to the first end of the one-way valve 313, and the second end of the one-way valve 313 is connected to the water outlet 32.

[0094] The NTC thermistor 312 is used to measure the temperature of the water being transported.

[0095] In one possible implementation, the water outlet module 30 includes a one-way valve 313 connected to the heating module 20; wherein the one-way valve 313 is used to control the discharge of a first type of liquid from the water outlet module and to prevent a second type of liquid from entering from the outside.

[0096] 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.

[0097] It should be noted that the one-way valve 313 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 other problems, and ensuring the normal operation of the water system. The main function of the one-way valve 313 in this embodiment is to prevent sterilizing water from being discharged from the faucet and to 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.

[0098] As the heated water flows towards the outlet 32, the NTC thermistor 312 installed in the internal water circuit monitors the water temperature in real time. The resistance of the NTC thermistor 312 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 temperature, the resistance of the NTC thermistor 312 is within the normal range. At this time, the control module 40 keeps the wastewater circuit of the drainage module 50 closed to supply water that meets the temperature requirements to the user.

[0099] Optionally, if the water temperature is lower than the set temperature, the resistance value of the NTC thermistor 312 will change, and this change will be detected by the control module 40. At this time, the control module 40 can determine that the water temperature is not up to standard based on the detected temperature and open the wastewater path of the drain module 50. Optionally, the substandard water can flow back through the wastewater path, usually returning to the heating module 20 through the drain module 50 for reheating until the temperature reaches the preset water temperature again, before being output for user use.

[0100] The precise temperature control mechanism ensures that the output water always meets the required temperature, preventing fluctuations in temperature and providing a consistently comfortable experience. Furthermore, it prevents the wasteful discharge of water that is not at the correct temperature. Instead of reheating all the water, the substandard water is returned for reheating, saving energy and improving the energy efficiency of the water supply system.

[0101] Please see Figure 13 As shown, Figure 13 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 three-way valve 51, a drainage power component 52, and a drainage component 53. The three-way valve 51 is connected to the water outlet module 30, the heating module 20, and the drainage power component 52. The drainage power component 52 is connected to the drainage component 53.

[0102] The first end of the three-way valve 51 is connected to the water outlet module 30, the second end of the three-way valve 51 is connected to the heating module 20, and the third end of the three-way valve 51 is connected to the drainage power component 52.

[0103] Drainage power unit 52 is used to transfer water to drainage unit 53;

[0104] Drainage component 53 is used to discharge water transmitted from the drainage power component.

[0105] It should be noted that the three-way valve 51 can distribute water flow in three different directions. This three-way valve 51 can switch between different water path branches or mix water flows. The three-way valve 51 can not only regulate the water flow path but also work in conjunction with other modules. For example, when the temperature detection unit detects that the water temperature does not meet the preset temperature, the three-way valve 51 can change the water flow path to guide the substandard water to one end of the connected drainage power component 52, thus preparing for subsequent reheating of this water.

[0106] The drainage power unit 52 is the key power source for realizing water recirculation. When the water temperature does not meet the requirements, the drainage power unit 52 can generate power through its own operation to drive the substandard water to flow in reverse along the predetermined water path. For example, water that was originally going to flow out of the outlet module 30 but was not hot enough can be reversed and transported towards the heating module 20 through the switching of the three-way valve 51, so that this water can return to the heating module 20 for reheating, ensuring that the final output water temperature meets the requirements, thereby ensuring that users can use water at a suitable temperature.

[0107] The return flow power provided by the drainage power component 52 can make the water temperature control of the entire water supply system more precise and stable, preventing water with substandard temperature from flowing out directly for user use; and since only the substandard part of the water needs to be reheated, instead of reheating all the water, it also helps to improve the energy efficiency of the entire system.

[0108] The wastewater may include excess water generated during the reheating process when the 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 via the drainage component 53 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.
