[0002] Against the backdrop of the booming health industry, the consumer demand for household water purifiers is constantly expanding the boundaries of product value beyond water quality safety requirements, with product functions evolving from safety to health and comfort. In addition to pure water products, products with a wide range of functions have emerged. Among them, the concept of boiled water (i.e., cooled boiled water) is deeply rooted in consumers' minds and has become a hot topic of concern.

[0003] Currently, most water purifiers on the market use an instant heating method. However, during the heating process using the boiling water setting, there is too much cold water. The boiled water must be boiled first and then the temperature controlled. The low-temperature water from the boiling water setting will be transferred to the boiled water setting, causing the water temperature at each setting to be lower than the set value. This results in the user getting cold water for the first cup of water, which limits the functionality of the water supply system and affects the user experience. Summary of the Invention

[0023] Fifthly, this application also provides a computer-readable storage medium.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] like Figure 1As shown, this application provides a water supply system 100, which includes a water supply module 102, a heating module 104, and a heat exchange module 106. The water supply module 102 provides drinking water at room temperature. The heat exchange module 106 has an outer pipe inlet, an outer pipe outlet, an inner pipe inlet, and an inner pipe outlet. The outer pipe inlet and outlet are connected, and the inner pipe inlet and outlet are also connected. The inlet of the heating module 104 is connected to the outlet of the water supply module 102, and the outlet of the heating module 104 is connected to the outer pipe inlet of the heat exchange module 106. The outer pipe outlet of the heat exchange module 106 is connected to the inner pipe inlet of the heat exchange module 106 via a pipeline, and the inner pipe outlet of the heat exchange module 106 is connected to the water outlet of the water supply system 100. Therefore, after the heating module 104 heats the water supplied by the water supply module 102 to the target heating temperature, the heated water can sequentially pass through the outer pipe inlet, outer pipe outlet, and inner pipe inlet of the heat exchange module 106 into the inner pipe of the heat exchange module 106. This heats the cooling water in the inner pipe to the target required temperature. Then, the heated cooling water is output to the water outlet of the water supply system 100 through the inner pipe outlet of the heat exchange module 106, ensuring that the first cup of water taken by the user is not cold water, but boiled water with a certain temperature that meets the user's needs. The target heating temperature refers to the boiling point temperature of water; for example, in most cases, the target heating temperature can be 100℃. The target required temperature refers to the temperature of the boiled water required by the user; for example, the target required temperature can be 55℃. In the following embodiments, the target heating temperature is 100℃ and the target required temperature is 55℃, as an example.

[0051] The heat exchange module can be a heat exchanger, etc.; the heating module has the functions of rapid, stable, and adjustable power heating. Specifically, the heating module includes an adjustable power heating element, which can include, but is not limited to, a positive temperature coefficient (PTC) heating element, a rare earth thick film heating element, or a metal heating tube, etc. The heating element raises the temperature of the water supply in contact with the heating element to boiling point, thus obtaining boiling water. The boiling water enters the U-shaped bend of the heat exchange module through the water inlet end of the outer pipe of the heat exchange module and flows on the outer wall of the inner metal pipe of the heat exchange module. The inner metal pipe has a corrugated turbulence shape to enhance the heat exchange effect. The inner metal pipe is placed in the U-shaped bend of the heat exchange module. An outer pipe is also installed in the U-shaped bend of the heat exchange module. The outer pipe and the inner pipe are separated by a thermally conductive material. Through heat conduction, the boiling water supply in the outer pipe is cooled down, and the cooled water supply in the inner pipe is heated up.

[0052] Combination Figure 1 In one embodiment, such as Figure 2As shown, the water supply system 100 also includes a controller 202, and a micro pump 204 and a regulating valve 206 electrically connected to the controller 202. The inlet of the micro pump 204 is connected to the outlet of the water supply module 102, and the outlet of the micro pump 204 is connected to the inlet of the regulating valve 206. The first outlet of the regulating valve 206 is connected to the inlet of the heating module 104. The micro pump 204 can refer to a water purification micro pump. Specifically, the controller 202, when the zero-cold-water control condition is met, controls the micro pump 204 to deliver water through the first outlet of the regulating valve 206 to the heating module 104. The zero-cold-water control condition refers to the condition under which the water supply system executes the zero-cold-water control process, which ensures that the first cup of water taken by the user is not cold water.

[0053] In some embodiments, the water supply system is equipped with a display screen showing a zero-cold-water button. The zero-cold-water button is used to control the water supply system to perform a zero-cold-water control process. When a user takes the first cup of water and finds that the first cup of water is cold, the user can trigger the zero-cold-water button by clicking or touching it. When a trigger operation is received for the zero-cold-water button, the controller can determine that the zero-cold-water control conditions are met, and then control the micro-pump to deliver the water supply through the first outlet of the regulating valve to the heating module.

[0054] Combination Figure 1 In some embodiments, the water supply system also includes a water pump that can be turned on when the zero cold water control condition is determined to be met, so that the water supply module can provide water supply.

[0055] Combination Figure 2 It should be noted that the water supply module has different system characteristics depending on the quality of the raw water. When the raw water is of drinking water quality, the water supply module may not have a purification system. It only uses conveying equipment (such as a pressure stabilizing pump or a micro pump) to deliver room temperature purified water from the outlet of the water supply module to the heating module. The water heated by the heating module then passes through the heat exchange module and the outlet of the water supply system. When the raw water is of non-drinking water quality, the water supply module may include a purification system to purify the raw water to meet drinking water standards. Then, the room temperature purified water from the purification system is diverted to the inlet of the heating module through conveying equipment and regulating valves. The water heated by the heating module is then delivered to the inlet of the outer pipe of the heat exchange module.

[0056] The purification system may include a pretreatment module and a deep treatment module, either individually or in combination. The pretreatment module is used to initially filter pollutants such as sediment, rust, and residual chlorine from the water. The pretreatment module may include a combination or composite of a primary filter cartridge and an activated carbon filter cartridge. The primary filter cartridge may include, but is not limited to, PP cotton filter cartridges and ultrafiltration filter cartridges. The activated carbon filter cartridge may include, but is not limited to, granular activated carbon, carbon fiber, and carbon rod filter cartridges. The deep treatment module is used to deeply filter toxic and harmful substances such as heavy metals and microorganisms from the water. The deep treatment module may include one or more combinations of ultrafiltration, nanofiltration, or reverse osmosis filtration modules.

[0057] Combination Figure 2 In one embodiment, the controller 202 is further configured to: calculate a first target temperature difference between the target heating temperature and the outlet water temperature of the water supply module; and determine the flow rate ratio of the water supply flowing into the heating module and the heating power of the heating module based on the first target temperature difference, so that the temperature of the water heated by the heating module matches the target heating temperature. Here, the target heating temperature refers to the boiling point temperature of water, which is 100°C; the outlet water temperature of the water supply module refers to the pure water temperature in the water supply module, for example, the outlet water temperature of the water supply module is 25°C.

[0058] The controller 202 can be implemented in various ways to determine the flow rate ratio of the water supply flowing into the heating module and the heating power of the heating module based on the first target temperature difference. As long as the water supply flowing into the heating module is heated by the heating power, the temperature of the heated water can be matched with the target heating temperature.

[0059] In some embodiments, a first mapping relationship between the temperature difference and the water supply receiving module is obtained, thereby determining the flow rate ratio of the water supply flowing into the heating module based on the first mapping relationship and the first target temperature difference. Specifically, in the first mapping relationship, when the temperature difference is 75°C and the water supply receiving module includes a heating module, the flow rate ratio of the water supply flowing into the heating module is 0.4 L / min. When the temperature difference is 30°C and the water supply receiving module includes both a heating module and a heat exchange module, the flow rate ratio of the water supply flowing into the heating module is 0.68 L / min, and the flow rate ratio of the water supply flowing into the heat exchange module is 0.16 L / min. The specific content of the first mapping relationship can be set according to the actual application scenario, and this embodiment does not impose specific limitations.

[0060] In some embodiments, a second mapping relationship between temperature difference and heating power is obtained, and then the heating power of the heating module is determined based on the second mapping relationship and the first target temperature difference.

[0061] In some embodiments, the heating power of the heating module can be determined according to a preset formula and a first target temperature difference. The preset formula satisfies the following equation: preset value * (T2 - T1) * V = P * η, where T2 represents the target heating temperature, T1 represents the outlet water temperature, the difference between T2 and T1 represents the first target temperature difference, P represents the heating power of the heating module, V represents the output flow rate of the micro-pump, and η represents the heating efficiency. In this embodiment, the preset value can be 4187.

[0062] Combination Figure 1 and Figure 2 In one embodiment, such as Figure 3 As shown, the water supply system 100 also includes a controller 202, and a first temperature sensor 302 and a level detector 304 electrically connected to the controller 202. The first temperature sensor 302 is located at the outlet of the heating module 104, and the level detector 304 is located within the water supply module 102. Specifically, the first temperature sensor 302 is used to detect the outlet water temperature of the heating module 104; the level detector 304 is used to detect the water level in the water supply module 102; and the controller 202 is used to determine that the zero-cold-water control condition is met when the outlet water temperature is lower than the intake water temperature and the water level is higher than a preset low level.

[0063] Combination Figure 2 In one embodiment, such as Figure 4 As shown, a water supply system 100 is provided. The water supply system 100 also includes a controller 202 and a first control valve 402 electrically connected to the controller 202. The first control valve 402 includes a first inlet end and an outlet end. The first inlet end of the first control valve 402 is connected to the first outlet end of a regulating valve 206, and the outlet end of the first control valve 402 is connected to the inlet end of a heating module 104. The inlet end of the regulating valve 206 is connected to the outlet end of the water supply module 102. Specifically, the controller 202 is used to control the connection between the first inlet end and the outlet end of the first control valve 402 when the zero cold water control condition is met. Thus, the water supplied by the water supply module 102 can flow through the inlet end of the regulating valve 206, through the first inlet end of the first control valve 402, reach the outlet end of the first control valve 402, and finally flow into the heating module 104 for heating.

[0064] Combination Figure 4In one embodiment, the first control valve 402 further includes a second inlet, which is connected to the outlet of the heat exchange module 106. Specifically, the controller 202 is used to connect the second inlet and outlet of the first control valve 402 when the water supply temperature at the outlet reaches the target required temperature. It should be understood that when the water supply temperature at the outlet reaches the target required temperature, the controller 202 controls the water supply system to perform a multi-temperature-segment boiled water preparation process, so that at any given time, the water supply temperature provided by the outlet of the water supply system can meet the user's water intake needs within a preset temperature range, for example, it can meet the water intake needs of 45℃-100℃.

[0065] Combination Figure 1 In one embodiment, such as Figure 5 As shown, the water supply system 100 also includes a controller 202 and a second control valve 502 electrically connected to the controller 202. The second control valve 502 includes an inlet end and a first outlet end. The inlet end of the second control valve 502 is connected to the outlet end of the heating module 104, and the first outlet end of the second control valve 502 is connected to the inlet end of the outer pipe of the heat exchange module 106. Specifically, the controller 202 is used to control the connection between the inlet end and the first outlet end of the second control valve 502 when the zero cold water control condition is met. This allows the water heated by the heating module 104 to flow through the second control valve 502 into the inlet end of the outer pipe of the heat exchange module 106 and reach the outer pipe of the heat exchange module 106.

[0066] Combination Figure 5 In one embodiment, such as Figure 6 As shown, the water supply system 100 also includes a regulating valve 206 and a third control valve 602. The regulating valve 206 includes an inlet end, a first outlet end, and a second outlet end. The third control valve 602 includes a first inlet end, a second inlet end, and an outlet end. The inlet end of the regulating valve 206 is connected to the outlet end of the water supply module 102. The first outlet end of the regulating valve 206 is connected to the inlet end of the heating module 104. The second outlet end of the regulating valve 206 is connected to the second inlet end of the third control valve 602. The first inlet end of the third control valve 602 is connected to the first outlet end of the second control valve 502. The outlet end of the third control valve 602 is connected to the inlet end of the outer pipe of the heat exchange module 106. Specifically, controller 202 is used to connect the first inlet and outlet of third control valve 602 when the zero cold water control condition is met; and to disconnect the inlet and first outlet of second control valve 502 and the first inlet and outlet of third control valve 602 when the water supply temperature of the outlet reaches the target required temperature, and to connect the inlet and second outlet of second control valve 502 and the second inlet and outlet of third control valve 602.

[0067] Combination Figure 6In one embodiment, the controller 202 is further configured to: calculate a second target temperature difference between the target demand temperature and the outlet water temperature of the water supply module when the water supply temperature of the outlet reaches the target demand temperature; and determine the flow rate ratio of the water supply flowing into the heating module and the flow rate ratio of the water supply flowing into the heat exchange module, as well as the heating power of the heating module, based on the second target temperature difference, so that the water supply temperature output by the heat exchange module reaches the target demand temperature.

[0068] For example, when the target temperature is 55℃ and the water supply temperature is 25℃, the second target temperature difference is 30℃. Based on the temperature difference of 30℃, the flow rate of the water flowing into the heat exchange module is determined to be 0.65L / min, and the flow rate of the water flowing into the heat exchange module is 0.16L / min.

[0069] Combination Figure 1 and Figure 2 In one embodiment, such as Figure 7 As shown, the water supply system 100 also includes a controller 202 and a fourth control valve 702 electrically connected to the controller 202. The fourth control valve 702 includes an inlet end and a first outlet end. The inlet end of the fourth control valve 702 is connected to the outlet end of the outer pipe of the heat exchange module 106, and the first outlet end of the fourth control valve 702 is connected to the outlet end of the inner pipe of the heat exchange module 106. Specifically, the controller 202 is used to connect the inlet end and the first outlet end of the fourth control valve 702 when the zero-cold-water control condition is met. This allows hot water in the outer pipe of the heat exchange module 106 to flow into the inner pipe of the heat exchange module through the fourth control valve 702, thereby exchanging heat with the cooling water in the inner pipe to the target required temperature.

[0070] Combination Figure 7 In one embodiment, such as Figure 8As shown, the water supply system 100 also includes a fifth control valve 802 electrically connected to the processor 202, and the fourth control valve 702 also includes a second outlet. The fifth control valve 802 includes a first inlet, a second inlet, and an outlet; the outlet of the fifth control valve 802 is connected to the inlet of the inner pipe of the heat exchange module 106, the first inlet of the fifth control valve 802 is connected to the first outlet of the fourth control valve 702, and the second inlet of the fifth control valve 802 is connected to the outlet of the heating module 104. Specifically, the controller 202 is also used to disconnect the inlet and first outlet of the fourth control valve 702 and the first inlet and outlet of the fifth control valve 802 when the water supply temperature at the outlet reaches the target required temperature, and to connect the inlet and second outlet of the fourth control valve 702 and the second inlet and outlet of the fifth control valve 802. This allows the water supply system to promptly execute the multi-temperature-range boiled water preparation process when the zero-cold-water control process is completed, ensuring that the water outlet of the water supply system can continuously provide boiled water at a fixed temperature (such as any temperature between 45℃ and 100℃) to meet the user's water needs.

[0071] In conjunction with the above, in one embodiment, such as Figure 9 The diagram shows a schematic of a water supply system 100. The water supply system 100 includes a water supply module 102, a micro pump 204, a regulating valve 206, a first control valve 402, a heating module 104, a first temperature sensor 302, a second control valve 502, a third control valve 602, a heat exchange module 106, a fourth control valve 702, a fifth control valve 802, a processor (not shown), a second temperature sensor 902, and a level detector (not shown). The first temperature sensor 302 is located at the outlet of the heating module 104 and is used to detect the outlet water temperature. The level detector 304 is located in the water supply module 102 and is used to detect the water level in the water supply module 102. A second temperature sensor 902 is located at the outlet of the water supply system and is used to detect the water supply temperature at the outlet. The outlet of the water supply module 102 can also be equipped with a third temperature sensor (not shown in the figure), which is used to detect the water temperature supplied by the water supply module (i.e., the water supply temperature); the outlet of the water supply system (not shown in the figure) can also be equipped with a fourth temperature sensor, which is used to detect the water temperature at the outlet of the water supply system. The control valve described above can be a 1-in-2-out stepless regulating valve or a 1-in-2-out solenoid valve, etc.

[0072] The inlet of the micro pump 204 is connected to the outlet of the water supply module 102. The outlet of the micro pump 204 is connected to the inlet of the regulating valve 206. The first outlet of the regulating valve 206 is connected to the first inlet of the first control valve 402. The outlet of the first control valve 402 is connected to the inlet of the heating module 104. The outlet of the heating module 104 is connected to the inlet of the second control valve 502. The first outlet of the second control valve 502 is connected to the first inlet of the third control valve 602. The outlet of the third control valve 602 is connected to the inlet of the outer pipe of the heat exchange module 106. The outer pipe inlet and outlet of heat exchange module 106 are connected. The outer pipe outlet of heat exchange module 106 is connected to the inlet of fourth control valve 702. The first outlet of fourth control valve 702 is connected to the first inlet of fifth control valve 802. The second outlet of fourth control valve 702 is connected to the second inlet of first control valve 402. The outlet of fifth control valve 802 is connected to the inner pipe inlet of heat exchange module 106. The inner pipe inlet and outlet of heat exchange module 106 are connected. The inner pipe outlet of heat exchange module 106 is connected to the outlet of water supply system 100. The second outlet of regulating valve 206 is connected to the second inlet of third control valve 602. The second outlet of second control valve 502 is connected to the second inlet of fifth control valve 802.

[0073] Specifically, when the outlet water temperature of the heating module is lower than the intake water temperature, and the water level in the water supply module is higher than the preset low level, the zero-cold-water control conditions are met. Therefore, the controller initiates the zero-cold-water control process for the water supply system. Figure 10 As shown, the water supplied by the water supply module 102 flows through the following paths in sequence: micro pump 204, the inlet and first outlet of regulating valve 206, the first inlet and outlet of first control valve 402, heating module 104, the inlet and first outlet of second control valve 502, the first inlet and outlet of third control valve 602, the inlet and outlet of the outer pipe of heat exchange module 106, the inlet and first outlet of fourth control valve 702, the first inlet and outlet of fifth control valve 802, the inlet and outlet of the inner pipe of heat exchange module 106, and the water outlet of the water supply system.

[0074] In other words, when the controller initiates the zero-cold-water control process of the water supply system, the water supplied by the water supply system 102 enters the heating module 104 through the micro pump 204, the inlet and first outlet of the regulating valve 206, and the first inlet and outlet of the first control valve 402. After the heating module 104 heats the water to the target heating temperature, the heated water sequentially passes through the inlet and first outlet of the second control valve 502, the first inlet and outlet of the third control valve 602, and the heat exchange module 106. The water inlet and outlet of the outer pipe, the water inlet and first outlet of the fourth control valve 702, the first water inlet and outlet of the fifth control valve 802, and the water inlet of the inner pipe of the heat exchange module 106 enter the inner pipe of the heat exchange module 106 to exchange the cooling water in the inner pipe to the target required temperature. Then, the cooled water after heat exchange is output to the water outlet of the water supply system 100 through the water outlet of the inner pipe of the heat exchange module 106, so that the first cup of water taken by the user is not cold water, but boiled water with a certain temperature that meets the user's needs.

[0075] For example, taking a target heating temperature of 100℃ (boiling point), a target required temperature of 55℃, and a water intake temperature of 40℃ as an example, the controller determines that the water level in the water supply module is higher than the preset low liquid level, and the water outlet temperature of the heating module is lower than 40℃. The controller then obtains a water supply temperature of 25℃ and calculates the temperature difference between the target heating temperature and the water supply temperature, obtaining a temperature difference of 75℃ (i.e., the first target temperature difference). Based on the temperature difference of 75℃, the micro pump outputs water at a rate of 0.4L / min. Simultaneously, the heating module synchronously selects its heating power based on the temperature difference of 75℃ to ensure that the water outlet temperature of the heating module reaches the target heating temperature. Thus, the boiling water from the heating module first enters the outer tube of the heat exchange module, and then enters the inner tube through the outlet of the outer tube and the inlet of the inner tube. This reverses the heat exchange to raise the temperature of the remaining cold water in the inner tube to 55℃, thereby achieving a zero-cold-water control process and meeting the user's need for 55℃ cooled boiled water.

[0076] Specifically, when the water temperature at the outlet reaches the target required temperature, the controller controls the water supply system to execute a multi-temperature-segment boiled water preparation process, such as... Figure 11As shown, the process includes three paths. The first path includes: micro pump 204, the inlet and first outlet of regulating valve 206, the first inlet and outlet of first control valve 402, heating module 104, the inlet and second outlet of second control valve 502, the second inlet and outlet of fifth control valve 802, and the inlet of the inner tube of heat exchange module. The second path includes: micro pump 204, the inlet and second outlet of regulating valve 206, the second inlet and outlet of third control valve 602, and the inlet of the outer tube of heat exchange module 106. The third path includes: the outlet of the outer tube of heat exchange module 106, the inlet and second outlet of fourth control valve 702, the second inlet and outlet of first control valve 402, and heating module 104.

[0077] Combining the three paths mentioned above, the specific process of the controller controlling the water supply system to perform the multi-temperature segment boiled water preparation process is as follows: When the water supply temperature at the outlet reaches the target required temperature, the water supplied by the water supply module 102 can be heated through the first path, and the hot water is input into the inner tube of the heat exchange module 106. At the same time, the ambient temperature water supplied by the water supply system 102 can be input into the outer tube of the heat exchange module 106 through the second path, so that the hot water in the inner tube of the heat exchange module 106 and the ambient temperature water in the outer tube can exchange heat, and the heat-exchanged water can be obtained in the outer tube of the heat exchange module. Furthermore, the heat-exchanged water can be output from the outer pipe to the heating module 104 for heating through the third path to reach the target heating temperature of boiling water (i.e., 100°C). The boiling water is then input into the inner pipe of the heat exchange module 106, so that the boiling water in the inner pipe can exchange heat with the room temperature water input into the outer pipe of the heat exchange module 106 through the second path. Finally, the water is output at a constant temperature to the water outlet of the water supply system through the water outlet of the inner pipe of the heat exchange module 106.

[0078] For example, taking a target heating temperature of 100℃ (i.e., boiling point) and a target demand temperature of 55℃ as an example, when the water supply temperature at the outlet reaches the target demand temperature, the controller obtains a supply water temperature of 25℃ and calculates the temperature difference between the target demand temperature and the supply water temperature, obtaining a temperature difference of 30℃ (i.e., the second target temperature difference). Based on the temperature difference of 30℃, the controller determines the micro-pump output flow rate to be 0.81L / min, meaning the controller determines the flow split ratio to be 0.8 based on the temperature difference. Therefore, based on the first path, ambient temperature water is supplied at a flow rate of 0.65L / min (i.e., the water flow ratio at the first outlet of the regulating valve) into the heating module for heating, and the obtained hot water flows into the inner pipe of the heat exchange module. Simultaneously, the regulating valve supplies water at a flow rate of 0.16L / min (i.e., the difference between 0.81L / min and 0.65L / min, i.e., the water flow ratio at the second outlet of the regulating valve) through the second path to... In the outer tube of the heat exchange module, the ambient temperature water in the outer tube exchanges heat with the hot water in the inner tube to a supply water of 70°C and 0.81L / min. After the heat exchanged water is reheated to the target heating temperature through a third path, it becomes boiling water. The boiling water is then input into the inner tube of the heat exchange module 106, so that the boiling water in the inner tube exchanges heat with the ambient temperature water of 0.65L / min input into the outer tube of the heat exchange module 106 through a second path. Then, a constant temperature and a fixed quantity (i.e., 0.81L / min) of cooled boiled water is output to the water outlet of the water supply system through the water outlet of the inner tube of the heat exchange module 106.

[0079] In conjunction with the above, in one embodiment, such as Figure 12 As shown, a control method for a water supply system is provided. Taking the application of this method to the controller 202 mentioned above as an example, the method includes the following steps:

[0080] S1202, determine whether the water supply system meets the zero cold water control conditions.

[0081] In this embodiment, the zero cold water control condition refers to the condition under which the water supply system executes the zero cold water control process, which is used to ensure that the first cup of water taken by the user is not cold water.

[0082] In some embodiments, the water supply system is equipped with a display screen showing a zero-cold-water button. The zero-cold-water button is used to control the water supply system to perform a zero-cold-water control process. When a user takes the first cup of water and finds that the first cup of water is cold, the user can trigger the zero-cold-water button by clicking or touching it. When a trigger operation is received for the zero-cold-water button, the controller can determine that the zero-cold-water control conditions are met.

[0083] S1204, if satisfied, control the heating module in the water supply system to heat the water supplied by the water supply module to the target heating temperature, so that the heated water sequentially passes through the outer pipe inlet, outer pipe outlet and inner pipe inlet of the heat exchange module in the water supply system to enter the inner pipe of the heat exchange module, so that the cooling water in the inner pipe is heated to the target required temperature, and then the heated cooling water is output to the water outlet of the water supply system through the inner pipe outlet of the heat exchange module.

[0084] Combination Figure 9 When the controller determines that the zero-cold-water control conditions are met, it controls the following: the inlet and outlet of the regulating valve are connected, but the inlet and outlet are not connected; the first inlet and outlet of the first control valve are connected, but the second inlet and outlet are not connected; the inlet and outlet of the second control valve are connected, but the second inlet and outlet are not connected; the first inlet and outlet of the third control valve are connected, but the second inlet and outlet are not connected; and the inlet and outlet of the fourth control valve are connected, but the second inlet and outlet are not connected. The first inlet and outlet of the fifth control valve are connected while the second inlet and outlet are not connected. This allows the heating module in the water supply system to heat the water supplied by the water supply module to the target heating temperature. The heated water then passes sequentially through the outer pipe inlet, outer pipe outlet, and inner pipe inlet of the heat exchange module in the water supply system and enters the inner pipe of the heat exchange module. After the cooling water in the inner pipe is heated to the target required temperature, the heated cooling water is output to the outlet of the water supply system through the inner pipe outlet of the heat exchange module.

[0085] In summary, based on Figure 12 The method described herein heats the water supplied by the water supply module to the target heating temperature through the heating module in the water supply system when the zero cold water control condition is met. The heated water then passes sequentially through the outer pipe inlet, outer pipe outlet, and inner pipe inlet of the heat exchange module in the water supply system before entering the inner pipe of the heat exchange module. After the cooling water in the inner pipe is heated to the target required temperature, the heated water is output to the water outlet of the water supply system through the inner pipe outlet of the heat exchange module. This solves the problem of cold water in the first cup of water taken from the water supply system due to residual water in the water supply system, ensuring that the first cup of water taken by the user is not cold water, but boiled water with a certain temperature that meets the user's needs. This expands the function of the water supply system and improves the user's experience with the water supply system.

[0086] The controller can use various possible methods to determine whether the water supply system meets the zero cold water control conditions, as long as it can ensure that the first cup of water taken by the user is not cold water.

[0087] In one embodiment, such as Figure 13 As shown, a flowchart illustrating the process for determining whether a water supply system meets the zero-cold-water control conditions is provided, including the following steps:

[0088] S1302, obtain the outlet water temperature of the heating module and the water level of the water supply module.

[0089] Combination Figure 9 The outlet water temperature can be obtained through the first temperature sensor installed at the outlet of the heating module, and the water level can be obtained through the level detector installed in the water supply module.

[0090] S1304: When the outlet water temperature is lower than the intake water temperature and the water level is higher than the preset low liquid level, the water supply system is determined to meet the zero cold water control conditions.

[0091] In summary, based on Figure 13 The method shown can determine that the water supply system meets the zero cold water control conditions. Thus, by initiating the zero cold water control process of the water supply system, the controller can ensure that the first cup of water taken by the user is not cold water, but boiled water with a certain temperature that meets the user's needs. This expands the function of the water supply system and improves the user's experience with the water supply system.

[0092] In one embodiment, such as Figure 14 The diagram shows a flow chart of a water supply system control method, including the following steps:

[0093] S1402, calculate the first target temperature difference between the target heating temperature and the outlet water temperature of the water supply module.

[0094] In this embodiment, the target heating temperature refers to the boiling point temperature of water, which is 100°C; the outlet water temperature of the water supply module refers to the pure water temperature in the water supply module, for example, the outlet water temperature of the water supply module is 25°C, and the outlet water temperature can also be called the water supply temperature or the temperature of the room temperature water supply.

[0095] S1404, based on the first target temperature difference, determine the flow rate ratio of the water supply flowing into the heating module and the heating power of the heating module, so that the temperature of the water heated by the heating module matches the target heating temperature.

[0096] In some embodiments, a first mapping relationship between the temperature difference and the water supply receiving module is obtained, thereby determining the flow rate ratio of the water supply flowing into the heating module based on the first mapping relationship and the first target temperature difference. Specifically, in the first mapping relationship, when the temperature difference is 75°C and the water supply receiving module includes a heating module, the flow rate ratio of the water supply flowing into the heating module is 0.4 L / min. When the temperature difference is 30°C and the water supply receiving module includes both a heating module and a heat exchange module, the flow rate ratio of the water supply flowing into the heating module is 0.68 L / min, and the flow rate ratio of the water supply flowing into the heat exchange module is 0.16 L / min. The specific content of the first mapping relationship can be set according to the actual application scenario, and this embodiment does not impose specific limitations.

[0097] In some embodiments, a second mapping relationship between temperature difference and heating power is obtained, and then the heating power of the heating module is determined based on the second mapping relationship and the first target temperature difference.

[0098] In some embodiments, the heating power of the heating module can be determined according to a preset formula and a first target temperature difference. The preset formula satisfies the following formula: 4187*(T2-T1)*V=P*η, where T2 represents the target heating temperature, T1 represents the outlet water temperature, the difference between T2 and T1 represents the first target temperature difference, P represents the heating power of the heating module, V represents the output flow rate of the micro pump, and η represents the heating efficiency.

[0099] In summary, based on Figure 14 The method shown determines the flow rate ratio of the water supply to the heating module and the heating power of the heating module based on the temperature difference between the target heating temperature and the outlet water temperature of the water supply module. This ensures that the temperature of the heated water matches the target heating temperature. Thus, after the water supply is heated by the heating module, boiling water is obtained. This boiling water then exchanges heat with the cooling water in the inner pipe to reach the target required temperature, ensuring that the water supplied to the user from the water outlet of the water supply system is not cold water.

[0100] In one embodiment, such as Figure 15 The diagram shows a flow chart of a water supply system control method, including the following steps:

[0101] S1502, obtain the water supply temperature of the water outlet of the water supply system.

[0102] Combination Figure 9 A fourth temperature sensor can be installed at the water outlet of the water supply system to obtain the water supply temperature of the outlet.

[0103] S1504 When the water supply temperature at the outlet reaches the target required temperature, the heating module is controlled to heat the water supply so that the heated water enters the inner tube of the heat exchange module and exchanges heat with the room temperature water supplied by the water supply module in the outer tube of the heat exchange module.

[0104] S1506 controls the heating module to heat the water supplied from the outer pipe of the heat exchange module to the target heating temperature, so that the water supplied to the target heating temperature exchanges heat with the room temperature purified water to the target required temperature, and then the water supplied to the target required temperature is output through the outlet of the heat exchange module.

[0105] In summary, based on Figure 15The method shown allows the water supply system to perform a multi-temperature-segment boiled water preparation process when the controller completes the zero-cold-water control process. This ensures that at any given time, the water temperature provided by the water outlet of the water supply system can meet the user's water intake needs within a preset temperature range, such as 45℃-100℃.

[0106] In one embodiment, such as Figure 16 The diagram shows a flow chart of a water supply system control method, including the following steps:

[0107] S1602, calculate the second target temperature difference between the target required temperature and the outlet water temperature of the water supply module.

[0108] S1604, based on the second target temperature difference, determine the flow rate ratio of water flowing into the heating module and the flow rate ratio of water flowing into the heat exchange module, as well as the heating power of the heating module, so that the water temperature output by the heat exchange module reaches the target required temperature.

[0109] In this embodiment, the method for determining the flow rate ratio of water flowing into the heating module and the flow rate ratio of water flowing into the heat exchange module, as well as the heating power of the heating module, based on the second target temperature difference, can be referred to the previously described method for determining the flow rate ratio of water flowing into the heating module and the heating power of the heating module based on the first target temperature difference, and will not be repeated here. The heating power of the heating module is determined according to a preset formula, which satisfies the following formula: 4187*(T2-T1)*V=P*η, where T2 represents the target required temperature, T1 represents the outlet water temperature, and the difference between T2 and T1 represents the second target temperature difference.

[0110] In summary, based on Figure 16 The method shown determines the flow rate ratios of water flowing into the heating module and the heat exchange module, as well as the heating power of the heating module, based on the second target temperature difference. This ensures that the water temperature output by the heat exchange module reaches the target required temperature. Consequently, at any given time, the water temperature provided by the water outlet of the water supply system can meet the user's water intake needs within a preset temperature range.

[0111] Combination Figures 14-16 The content shown, in one embodiment, is as follows: Figure 17 The diagram shows a flow chart of a water supply system control method, including the following steps:

[0112] S1702, obtain the outlet water temperature of the heating module and the water level of the water supply module; when the outlet water temperature is lower than the intake water temperature and the water level is higher than the preset low liquid level, determine that the water supply system meets the zero cold water control conditions.

[0113] S1704, calculate the first target temperature difference between the target heating temperature and the outlet water temperature of the water supply module; based on the first target temperature difference, determine the flow rate ratio of the water supply flowing into the heating module and the heating power of the heating module, so that the temperature of the water supplied by the heating module after heating is matched with the target heating temperature.

[0114] S1706 controls the heating module in the water supply system to heat the water supplied by the water supply module to the target heating temperature, so that the heated water sequentially passes through the outer pipe inlet, outer pipe outlet and inner pipe inlet of the heat exchange module in the water supply system to enter the inner pipe of the heat exchange module, so that the cooling water in the inner pipe is heated to the target required temperature, and then the heated cooling water is output to the water outlet of the water supply system through the inner pipe outlet of the heat exchange module.

[0115] S1708: Obtain the water supply temperature of the water outlet of the water supply system; when the water supply temperature of the water outlet reaches the target required temperature, calculate the second target temperature difference between the target required temperature and the water outlet temperature of the water supply module; based on the second target temperature difference, determine the flow rate ratio of the water flowing into the heating module and the flow rate ratio of the water flowing into the heat exchange module, as well as the heating power of the heating module, so that the water supply temperature output by the heat exchange module reaches the target required temperature.

[0116] S1710, the control heating module heats the water supply so that the heated water enters the inner tube of the heat exchange module and exchanges heat with the room temperature water supplied by the water supply module in the outer tube of the heat exchange module; the control heating module heats the water supplied after heat exchange from the outer tube of the heat exchange module to the target heating temperature so that the water heated to the target heating temperature exchanges heat with the room temperature purified water to the target required temperature, and then outputs the water supply at the target required temperature through the outlet of the heat exchange module.

[0117] The specific contents of S1702-S1710 can be found in the aforementioned description and will not be repeated here.

[0118] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0119] Based on the same inventive concept, this application also provides a control device for a water supply system to implement the control method for the water supply system described above. The solution provided by this module is similar to the implementation scheme described in the above method; therefore, the specific limitations in one or more embodiments of the control device for the water supply system provided below can be found in the limitations of the control method for the water supply system described above, and will not be repeated here.

[0120] In one embodiment, such as Figure 18 As shown, a control device for a water supply system is provided, including a determining module 1802 and a control module 1804. The determining module 1802 is used to determine whether the water supply system meets the zero-cold-water control condition. The control module 1804, if the condition is met, controls the heating module in the water supply system to heat the water supplied by the water supply module to a target heating temperature. The heated water then sequentially passes through the outer pipe inlet, outer pipe outlet, and inner pipe inlet of the heat exchange module in the water supply system before entering the inner pipe of the heat exchange module. After exchanging heat with the cooling water in the inner pipe to the target required temperature, the heated cooling water is output to the outlet of the water supply system through the inner pipe outlet of the heat exchange module.

[0121] In one embodiment, the determining module 1802 is further configured to: obtain the outlet water temperature of the heating module and the water level of the water supply module; and determine that the water supply system meets the zero cold water control conditions when the outlet water temperature is lower than the intake water temperature and the water level is higher than the preset low liquid level.

[0122] In one embodiment, the control module 1804 is further configured to: calculate a first target temperature difference between the target heating temperature and the outlet water temperature of the water supply module; and determine the flow rate ratio of the water supply flowing into the heating module and the heating power of the heating module based on the first target temperature difference, so that the temperature of the water supplied by the heating module after heating is matched with the target heating temperature.
