[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1 , Figure 1 The water supply device control method provided by the embodiment of the present invention can be applied to Figure 1 The water supply device shown. Figure 1 As shown, 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; the water inlet module 10 is connected to the heating module 20, and is used to control the amount of water entering the water supply device 1; the heating module 20 is connected to the water inlet module 10 and the water outlet module 30, and is used to heat the water entering the heating module 20, and store the heated water; the water outlet module 30 is connected to the heating module 20, and is used to output water that meets a preset temperature; the control module 40 is connected to the water inlet module 10, the heating module 20 and the water outlet module 30, and is used to control the water inlet module 10, the heating module 20, and the water outlet module 30 to work.

[0026] Specifically, by Figure 1It can be seen that the external water source can be fed from the water inlet 11, and the water inlet 11 is connected to a flow meter 122 for measuring the water flow, and a flow control valve 131 and an on-off valve 132 for controlling the distribution of water flow; the flow meter 122 is connected to the heating energy storage unit 21 (taking the hot tank as an example), the hot tank has a heater (i.e., heating unit 211) and an exhaust port (i.e., gas release unit 23), wherein the exhaust port can be connected to a one-way valve (not shown in the figure); the hot tank is connected to the instant heating unit 22 for rapid heating, and a three-way valve 51 for reflux and discharge of waste water, i.e., the hot unit 22 is connected to a two-way valve 311 to transport the heated water to the internal faucet pipeline equipped with an NTC thermistor 312, and the NTC thermistor 312 is connected to a one-way valve 313 for outputting water of a preset temperature. It can be seen that the figure also includes a hot water return pipeline, i.e., the two-way valve 311 is connected to the three-way valve 51, so as to return water whose water temperature does not meet the standard.

[0027] The present invention controls the water inlet amount of the water system of the water supply device through the water inlet module 10, and controls the heating module 20 to heat the water entering the water system of the water supply device and store the water obtained after heating through the water supply device control method provided by the embodiment of the present invention, and then detects the water temperature through the water outlet module 30, and outputs water meeting the preset temperature, and further controls the water inlet module, the heating module, and the water outlet module to work through the control module 40, thereby realizing stable heating of the water entering the water system of the water supply device, and effectively performing temperature feedback and real-time adjustment mechanism, thereby achieving the purpose of more stably supplying water meeting the preset temperature.

[0028] See also Figure 2 As shown, Figure 2 A flow chart of a water supply device control method provided by an embodiment of the present invention includes the following steps:

[0029] S1: Obtain a drainage signal, where the drainage signal carries the current outlet water temperature.

[0030] Among them, the drainage signal can be an information carrier that is triggered when it is detected that (the user) needs to use water and is about to start drainage. The drainage signal can carry the current water outlet temperature. Optionally, a special temperature detection device can be provided inside the water supply device, and the device can be located in the water pipe near the water outlet module. When the water flows through the temperature detection device, the detection device can monitor the temperature of the water flow in real time, and use this temperature data as the current water outlet temperature information. The control module of the water supply device can receive a trigger signal indicating that drainage is about to start, and the trigger signal can be integrated with the current water outlet temperature data to further form a drainage signal.

[0031] Optionally, the water outlet module in the embodiment of the present application can only discharge water that meets the temperature standard, that is, the water outlet component is opened only when the water temperature meets the standard; if the temperature does not meet the standard, it can be refluxed through the drainage module to enter the heating module again for reheating, that is, the water outlet component will not be opened when the water temperature does not meet the standard. Optionally, the water outlet module can also first discharge water that does not meet the temperature standard, and display the water temperature (such as red flashing display) to prompt the user that the water temperature does not meet the standard at this time; then discharge water that meets the temperature standard, and display the water temperature (such as green stable display) to prompt the user that the water temperature has met the standard at this time. This application does not limit this.

[0032] Exemplarily, the above-mentioned temperature detection device can be provided in the water outlet module inside the water supply device. For example, a negative temperature coefficient (NTC) thermistor can be installed in the water outlet module to detect the water temperature of water passing through the NTC thermistor in real time. This application does not impose any restrictions on this.

[0033] Optional, such as Figure 1 As shown, the water outlet module 30 includes a two-way valve 311, a negative temperature coefficient NTC thermistor 312, a one-way valve 313 and a water outlet component 314, wherein the first end of the two-way valve 311 is connected to the heat exchanger 21 of the heating module 20 and the on-off valve 132 of the water inlet module 10, and the second end of the two-way 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 component 314, wherein the NTC thermistor 312 is used to measure the temperature of the transported water; and the water outlet component 314 is used to output water that meets a preset temperature.

[0034] It should be noted that the water outlet module 30 can perform accurate water temperature detection to further perform water temperature screening and waterway diversion. Through the above-mentioned strict temperature screening mechanism, the entire water supply device system can always provide users with stable water that meets temperature requirements, which can not only improve user satisfaction, but also improve the practicality of the entire system. Optionally, the diversion function of the water outlet module 30 also contributes to the stable operation of the system. After the water with unqualified water temperature is discharged to the drainage module 50, the system can take corresponding measures according to the specific circumstances, such as reheating the water with unqualified water temperature or checking whether the heating module 20 is faulty, etc., so as to ensure the continuous and stable operation of the entire system.

[0035] When the water obtained after heating flows to the water outlet component 314, the NTC thermistor 312 installed in the internal waterway will monitor the water temperature in real time. The resistance value of the NTC thermistor 312 is negatively correlated with the temperature, that is, the resistance value decreases when the temperature rises, and the resistance value increases when the temperature decreases. When the water temperature reaches the set qualified temperature, the resistance value of the NTC thermistor 312 is in a normal range. At this time, the control module can keep the waterway between the two-way valve 311 and the drainage module 50 closed to provide water with the required temperature for users. Optionally, the waterway between the two-way valve 311 and the drainage module 50 can be a reflux waterway for water whose water temperature does not meet the standard.

[0036] Optionally, if the water temperature is lower than the set qualified temperature, the resistance value of the NTC thermistor 312 changes, and the change is detected by the control module. At this time, the control module can determine that the water temperature does not meet the standard based on the detected temperature, and the water path between the two-way valve 311 and the drainage module 50 is closed, so that the water that does not meet the water temperature can flow back through the water path, usually through the drainage module 50 to the heating module 20 for reheating, until the temperature reaches the qualified standard again, so as to be further output for user use.

[0037] The precise temperature control mechanism of the water circuit structure can ensure that the output water always meets the temperature requirements, and will not be affected by the water temperature fluctuating, and can avoid the wasteful discharge of water that does not meet the temperature requirements. Recirculating the water that does not meet the temperature requirements for reheating instead of reheating all the water helps save energy and improve the energy efficiency of the water supply device.

[0038] S2: In response to the drainage signal, obtaining the first energy data of the heating module, the initial water temperature data of the water input by the water inlet module, the braking power data of the heating module and the water temperature requirement information.

[0039] An energy monitoring unit can be provided in the heating module of the water supply device to monitor the energy storage or consumption inside the heating module in real time, and the above-mentioned first energy data can be obtained. The first energy data can be used to indicate energy-related information of the heating module, such as the remaining thermal energy value in the heating element or the energy value corresponding to the consumed electrical energy, etc., and this application does not impose any restrictions on this. When the service end receives the drainage signal, it can send a command to the energy monitoring unit to obtain the energy data in the current heating module.

[0040] A water temperature sensor can be installed at the water inlet pipe of the water inlet module to detect the water temperature entering the water supply device, so as to obtain the above initial water temperature data. When the drainage signal is triggered, the server can immediately read the data of the water temperature sensor, which is the initial water temperature data.

[0041] The control module of the water supply device may pre-store the braking power information of the heating module to obtain the braking power data of the heating module. The braking power data may be determined according to the design specifications of the heating module. For example, the rated power of the heating element is 3000 watts, and the rated power of 3000 watts may be the information included in the braking power data.

[0042] The water temperature requirement information may be preset by the user or set by the system by default, and this application does not limit this. The water temperature requirement information may be used to indicate the desired water temperature information. For example, the user may set the desired water temperature through the operation panel of the water supply device, such as setting it to 45°C. In this case, the water temperature requirement information may be 45°C.

[0043] S3: Determine temperature control data according to the first energy data, the initial water temperature data, the energy generating power data, the current water outlet temperature and the water temperature demand information.

[0044] The temperature control data may be related data for indicating how to accurately control the temperature. The temperature control data may include, but is not limited to, heating time data, heating power data, heating power adjustment data, temperature change data, temperature change rate data, and heating mode data, etc., and this application does not limit this.

[0045] In one possible implementation, Figure 1 It can be seen that 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, wherein the heating energy storage unit 21 includes a heating unit 211 and a heat storage unit 212, the heating unit 211 is used to heat the water entering the heating energy storage unit 21; the heat storage unit 212 is used to store the water entering the heating energy storage unit 21; the instant heating unit 22 is used to heat the water output by the heating energy storage unit 21 and / or the water output by the water inlet module.

[0046] It should be noted that the medium of the heating unit 211 can be water or oil, and this application does not impose any restrictions on this. The heating energy storage unit 21 can be a hot 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, and play a role in buffering and continuously supplying water that meets the preset temperature. The instant heating unit 22 can be a thick film instant heater, which can be used to quickly heat water. Combining the instant heating unit 22 with the heat storage function of the heating energy storage unit 21 can provide water at a preset temperature quickly when it is needed, thereby improving the efficiency of supply.

[0047] In a possible implementation, the temperature control data includes first sub-temperature control data of the heating energy storage unit and second temperature control data of the instant heating unit, and determining the temperature control data according to the first energy data, the initial water temperature data, the energy generating power data, the current outlet water temperature and the water temperature demand information may include the following steps;

[0048] S31: determining a first temperature difference according to the current outlet water temperature and the water temperature requirement information, and determining a second temperature difference according to the water temperature requirement information and the initial water temperature data;

[0049] S32: determining energy demand information according to the first temperature difference, the second temperature difference and the first energy data;

[0050] S33: Determine the first sub-temperature control data and the second sub-temperature control data according to the energy demand information and the braking power data.

[0051] Among them, the first temperature difference can reflect the difference between the current outlet water temperature and the desired water temperature demand information. The calculation method can be: ΔT1 = water temperature demand information - current outlet water temperature. For example, if the water temperature demand information is set to 45°C, and the current outlet water temperature is 30°C, then ΔT1 = 45-30 = 15°C. The first temperature difference can intuitively show the degree of deviation between the current hot water supply temperature and the ideal temperature, which is one of the important bases for determining the heating strategy in the subsequent steps.

[0052] The second temperature difference can reflect the difference between the initial water temperature of the water input from the water inlet module and the desired water temperature requirement information. The calculation method can be: ΔT2 = water temperature requirement information - initial water temperature data. For example, if the initial water temperature data is 15°C and the water temperature requirement information is 45°C, then ΔT2 = 45-15 = 30°C. The second temperature difference can help evaluate the overall energy input required to heat the water to the desired temperature, and can play a key role in considering the energy allocation of the heating module.

[0053] The first temperature difference can indicate the current degree of temperature deficiency. The second temperature difference can be reflected in the temperature change corresponding to the overall energy demand when heating from the initial state with ideal energy loss. The first energy data can represent the existing energy reserve of the heating module. By analyzing the proportional relationship between the first temperature difference and the second temperature difference, it is possible to understand the stage of the current heating process and the proportion of heating that has been completed. For example, if the first temperature difference is smaller than the second temperature difference, it means that more heating tasks have been completed, then the energy demand information required to be supplemented will be reduced accordingly, otherwise it will increase.

[0054] Combined with the first energy data, if there is a large amount of energy reserves and the first temperature difference is small, the actual energy demand information that needs to be supplemented will be further reduced; if there is little energy reserves and the first temperature difference is large, a large amount of energy will be needed to reach the energy level corresponding to the water temperature demand information, thereby determining accurate energy demand information for subsequent reasonable allocation to the heating energy storage unit and instant heating unit for precise heating control.

[0055] In a possible implementation, the process of determining the first sub-temperature control data and the second sub-temperature control data according to the energy demand information and the braking power data may include the following steps:

[0056] S331: Determine a target heating power according to the energy demand information;

[0057] S332: extracting the first heating power of the heating energy storage unit and the second heating power of the instant heating unit from the energy generating power data;

[0058] S333: Determine the first sub-temperature control data and the second sub-temperature control data according to the target heating power, the first heating power, and the second heating power.

[0059] Among them, the target heating power can be used to indicate the heating power that should be provided per unit time in order to meet the energy required to heat the water to a preset temperature. The target heating power can be determined based on the energy demand information. It is understandable that if a large amount of water is to be heated in a short period of time to a higher preset temperature, the energy demand will be high and the target heating power will be relatively large; conversely, if the amount of water is small and the temperature difference is small, the target heating power will be smaller. The target heating power can be a power reference value obtained by comprehensively considering factors such as the extent of the water temperature increase, the amount of water, and the expected heating time.

[0060] The first heating power may be the heating power of the heating energy storage unit, which is determined by its design and manufacturing specifications, and may reflect the ability of the heating energy storage unit to convert electrical energy or other energy sources into thermal energy per unit time, that is, the ability of the heating energy storage unit to heat water.

[0061] The second heating power may be the heating power of the instant heating unit. The instant heating unit may be used to quickly heat water or fine-tune the water temperature. The second heating power may be determined by design parameters of the instant heating unit, such as the performance and size of its thick film heating element.

[0062] Optionally, the first heating power and the second heating power can be obtained from the control system parameter setting by table lookup. Optionally, a power meter can be used to actually measure the heating power of the heating energy storage unit and the instant heating unit. If the power meter is connected to the circuit of the water supply device, when the heating module and the instant heating unit are working, the power meter can display the power consumption of the heating energy storage unit and the instant heating unit in real time to accurately measure the heating power in the actual working environment, and this application does not limit this.

[0063] The first sub-temperature control data may be used to indicate a set of parameters for controlling the working state of the heating energy storage unit, which may include but are not limited to the working time of the heating energy storage unit, the working mode (such as continuous heating or intermittent heating), the heating power adjustment coefficient, etc. For example, if the target heating power is greater than the first heating power, the heating energy storage unit may need to work at a higher power for a longer time, and the time and power adjustment information may constitute a part of the first sub-temperature control data.

[0064] The second sub-temperature control data may be used to indicate control parameters for the instant heating unit, and may include but are not limited to the start-up time, working time, heating power adjustment strategy, etc. of the instant heating unit. For example, if the outlet water temperature is close to the preset temperature, the instant heating unit may work at a lower power for a short time, and the parameters related to the working mode may constitute part of the second sub-temperature control data.

[0065] In a possible implementation, if the target heating power is greater than the first heating power, the power allocation information is determined according to the ratio of the first heating power to the second heating power; the first sub-temperature control data and the second sub-temperature control data are determined according to the power allocation information, the target heating power, the first heating power, and the second heating power; if the target heating power is greater than the second heating power and less than the first heating power, the power difference between the target heating power and the second heating power is obtained; the first sub-temperature control data is determined according to the power difference, and the second sub-temperature control data is determined according to the second heating power; if the target heating power is less than the second heating power, the second sub-temperature control data is determined according to the target heating power, and the first sub-temperature control data is empty.

[0066] When the target heating power is greater than the first heating power of the heating energy storage unit, it means that the heating energy storage unit alone cannot meet the total heating demand, and the instant heating unit needs to work together to supplement the heat. At this time, the power allocation information can be determined by the ratio of the first heating power to the second heating power. The ratio can reflect the proportion of heating responsibility that the heating energy storage unit and the instant heating unit should each bear in the entire heating task. The power allocation information can provide a basis for determining the specific working parameters of the two components (i.e., the heating energy storage unit and the instant heating unit) in subsequent steps.

[0067] Based on the above power allocation information and parameters such as the target heating power, the working time of the heating energy storage unit, whether the working mode needs to be adjusted, and other information can be further determined. Furthermore, according to the change of water temperature during the entire heating process and the difference from the preset temperature, it can also be determined whether the heating energy storage unit should adopt intermittent heating and other modes, related mode parameters and other information, so as to obtain the first sub-temperature control data. Based on the power allocation information and the target heating power, the start-up time, working time, and heating power adjustment strategy of the instant heating unit can be determined to obtain the second sub-temperature control data.

[0068] In the case where the target heating power is greater than the second heating power of the instant heating unit but less than the first heating power of the heating energy storage unit, the power difference between the target heating power and the second heating power can be obtained. The power difference can reflect the excess heating capacity of the heating energy storage unit relative to the target heating power in terms of meeting the overall heating demand. Through the power difference, it can be analyzed how the heating energy storage unit needs to adjust its working state to adapt to the target heating power. Optionally, the working state adjustment of the heating energy storage unit can be determined based on the power difference, such as determining the corresponding power adjustment coefficient, working time and other parameters, so as to obtain the first sub-temperature control data.

[0069] For the instant heating unit, since the target heating power is greater than the second heating power, the instant heating unit can work at full load, or make appropriate power adjustments according to the water temperature in a state close to full load to contribute as much heat as possible. At this time, the second sub-temperature control data can be the relevant parameters when the instant heating unit is running at full power, as well as the corresponding fine-tuning power and other control strategy information when the water temperature is close to the preset temperature during the working process, and this application does not limit this.

[0070] Optionally, the power of the heating energy storage unit and the instant heating unit can be allocated according to the power difference between the target heating power and the second heating power, and according to the ratio of the first heating power to the second heating power. For example, the instant heating unit is allocated to perform heating work at 80% of the rated power, and the heating energy storage unit is allocated to complete the remaining heating work, so as to avoid the loss caused by the instant heating unit working at full load. This can not only ensure the overall heating efficiency so that the water can reach the preset temperature smoothly, but also reduce the workload of the instant heating unit, extend its service life, and reduce the probability of equipment failure, thereby improving the reliability and economy of the heating system of the entire water supply device.

[0071] When the target heating power is less than the second heating power, it means that the entire heating task can be completed mainly by the instant heating unit. At this time, the heating energy storage unit basically does not need to participate in the work, so the first sub-temperature control data can be determined to be empty. As for the second sub-temperature control data, the specific working parameters of the instant heating unit can be determined based on the target heating power, such as determining the start time of the instant heating unit, the working time, and whether power fine-tuning is required, etc., so that the instant heating unit can accurately provide the heat that just meets the demand to reach the preset water temperature.

[0072] In one possible implementation, if the target heating power is less than the second heating power, the water flow rate in the instant heating unit is extracted; the first actual heating power of the instant heating unit is determined based on the target heating power and the water flow rate; and the first actual heating power is determined as the second temperature control data.

[0073] The above-mentioned water flow rate can be used to indicate how fast the water flows in the internal pipes of the instant heating unit, and is usually measured by the volume of water flowing through per unit time (such as liters / minute). When the target heating power is less than the second heating power, by extracting the water flow rate in the instant heating unit, we can further understand the actual effect of the instant heating unit on heating the water, thereby determining the actual heating power required. For example, when the water flow rate is fast, the water stays in the instant heating unit for a short time, and a higher heating power is required to raise the water temperature to the preset temperature in a short time; when the water flow rate is slow, the water has a relatively longer time to be heated, and the actual heating power required can be relatively smaller. By obtaining the water flow rate, it is possible to accurately determine the actual heating power that the instant heating unit should use later.

[0074] Further calculations are performed based on the target heating power and the water flow rate to determine the first actual heating power. The target heating power can determine the total heating power level required to heat the water to a preset temperature, and the water flow rate can determine the length of time the water receives heat in the instant heating unit. Optionally, the actually required heating power can be calculated based on the heat transfer principle and the heating characteristics of the instant heating unit, which is not limited in this application.

[0075] In a possible implementation, the intermediate heating power can be determined according to the target heating power and the water flow rate; the thermal conduction efficiency of the instant heating unit can be extracted; and the first actual heating power can be determined according to the thermal conduction efficiency and the intermediate heating power.

[0076] The intermediate heating power may be a heating power value obtained by preliminary calculation under the condition of considering the influence of water flow velocity on the heating effect. The intermediate heating power may be an intermediate quantity connecting the target heating power and the actual heating power, and may be used in subsequent steps to determine the final actual heating power in combination with the heat conduction efficiency of the instant heating unit.

[0077] The heat transfer efficiency can be used to indicate the ability of the instant thermal unit to convert input energy (such as electrical energy) into heat energy and effectively transfer it to the water flow. The heat transfer efficiency can be a proportionality coefficient, and the range of the proportionality coefficient can be between 0 and 1.

[0078] By calculating the intermediate heating power and combining it with the heat conduction efficiency to determine the first actual heating power, the heating requirements of the instant heating unit under actual working conditions can be more accurately reflected. In the actual heating process, not only the influence of the water flow rate on the heating time (reflected by the intermediate heating power) but also the energy transfer efficiency of the instant heating unit itself (reflected by the heat conduction efficiency) should be considered. Accurately determining the first actual heating power can effectively control the heating process of the instant heating unit, thereby avoiding the situation where the water temperature does not meet the preset requirements due to insufficient or excessive heating power.

[0079] The first actual heating power is determined as the second temperature control data, that is, the first actual heating power is determined as the core parameter for controlling the operation of the instant heating unit. In the temperature control process of the entire water supply device, the second temperature control data (that is, the first actual heating power) guides the instant heating unit on how to heat the water that is about to flow out. The instant heating unit will start and operate according to this determined actual heating power, and continuously output corresponding heat to the water passing through to ensure that the water finally flowing out of the water outlet component of the water supply device can reach the preset temperature.

[0080] In a possible implementation, the water supply device may implement the step of determining the temperature control data according to the first energy data, the initial water temperature data, the energy generating power data, the current outlet water temperature and the water temperature demand information according to the following process:

[0081] S1, receiving a water taking instruction (such as the drainage signal carrying the current stable water output), responding to the water taking instruction, and starting the temperature control function;

[0082] S2, detecting and obtaining the difference ΔT between the inlet water temperature and the required outlet water temperature, the required outlet water temperature T1, and the hot tank water temperature T2;

[0083] S3, if T2 ≥ 95℃, and

[0084] ① ΔT≤10℃, then the thick film heating (such as the instant heating unit mentioned above) starts, and the water flow rate can be 3L / min;

[0085] ② ΔT>10℃, T1≤55℃, then the plate heat exchanger (such as the above-mentioned heating energy storage unit) is started, and the water outlet flow rate can be 3L / min;

[0086] ③ ΔT>10℃, 55℃<T1≤75℃, the plate heat exchanger starts heating, and the water outlet flow rate can be 2L / min;

[0087] ④ΔT>10℃, 75℃<T1, the plate exchanger and thick film heating are started, and the water outlet flow rate can be 1.5L / min;

[0088] S4, if 85℃≤T2<95℃, and

[0089] ① ΔT≤10℃, the thick film heating starts and the water flow rate can be 3L / min;

[0090] ② ΔT>10℃, T1≤55℃, then the plate exchanger and / or thick film heating is started, and the water outlet flow rate can be 3L / min;

[0091] ③ ΔT>10℃, 55℃<T1≤75℃, the plate heat exchanger starts heating, and the water outlet flow rate can be 2L / min;

[0092] ④ΔT>10℃, 75℃<T1, the plate exchanger and thick film heating are started, and the water outlet flow rate can be 1.5L / min;

[0093] S5, if T2<85℃, and

[0094] ① ΔT≤10℃, the thick film heating starts and the water flow rate can be 3L / min;

[0095] ②If ΔT>10℃, the plate exchanger and / or thick film heating will start, and the water flow rate can be adjusted according to the temperature.

[0096] It should be noted that when ΔT≤10°C, it means that the inlet water temperature and the outlet water temperature are relatively close. At this time, the instant heating unit is mainly used to control the water temperature, and the heating energy storage unit does not need to work because the heating energy storage unit is not needed to supplement or release a large amount of heat to adjust the water temperature.

[0097] When ΔT>10℃, it means that the difference between the inlet water temperature and the outlet water temperature is large, and the working mode of the two units needs to be further determined according to the current outlet water temperature. Since the difference between the inlet water temperature and the outlet water temperature is large at this time, the instant heating unit or the heating energy storage unit working alone may not meet the heating demand or achieve the best heating effect. Therefore, it is necessary to flexibly adjust the working state of the heating energy storage unit and the instant heating unit according to the specific outlet water temperature so that they can work together to achieve the appropriate outlet water temperature.

[0098] S4: According to the temperature control data, the heating module is controlled to heat the water in the heating module.

[0099] The temperature control data obtained after a series of complex calculations and analyses takes into account various factors such as the initial state of the water temperature, the target state, and the various characteristics of the heating module itself, and can be used to accurately guide the key parameters of the heating module. According to the temperature control data, the heating module is controlled to heat the water in the heating module, which can ensure that the heating module can heat the water inside in an appropriate manner, so that the final output hot water temperature can accurately meet the preset temperature requirements, thereby meeting the user's expectations for water temperature stability and accuracy.

[0100] Optionally, the step of controlling the heating module to heat the water in the heating module according to the temperature control data may be a step of mixing water at normal temperature with water heated by the heating module, so that when a large flow of water with a preset water temperature is required, water that meets both the flow requirement and the water temperature requirement can be output, and the present application does not impose any restrictions on this.

[0101] It can be seen that in the above scheme, the server can respond to the drainage signal by obtaining the drainage signal carrying the current water outlet temperature, and further obtain the first energy data of the heating module, the initial water temperature data of the water input by the water inlet module, the braking power data of the heating module and the water temperature requirement information, so that the temperature control data can be determined according to the first energy data, the initial water temperature data, the braking power data, the current water outlet temperature and the water temperature requirement information, and then the heating module can be controlled according to the temperature control data to heat the water in the heating module, which is beneficial to improve the accuracy of the water temperature control process of the water supply device and helps to achieve the purpose of more precise and effective water temperature control.

[0102] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
