[0035] Among them, the heat exchange module 21 can be a device that transfers heat from one fluid to another fluid by means of heat conduction, convection and radiation. The larger the heat transfer area of ​​the heat exchange module, the more heat can be transferred under the same conditions, and the higher the heating efficiency is. In the single heat host water channel solution provided in the present application, the heat transfer area of ​​the heat exchange module can be designed to be large enough to achieve the purpose of more effectively transferring heat to the fluid.

[0037] The circulating water pump 23 is used to transport the water stored in the heating energy storage module 22 to the heat exchange module 21 .

[0038] It should be noted that the medium of the heating energy storage module 21 can be water or oil, and this application does not limit this.

[0044] The flow control unit 13 is used to control the flow of water entering the water outlet module 10 and the heating energy storage module 22 .

[0045] It should be noted that the water inlet 11 is the entrance for water to enter the water system of the water supply device, and is the starting point of the entire water cycle. The external water source can enter the water system of the water supply device through the water inlet 11. The flow detection unit 12 can be used to measure the water flow input to the heat exchange module 21. By measuring the water flow entering the heat exchange module 21, the system can better control the heating process. For example, the heating power is adjusted according to the flow rate to ensure that the water can be fully and efficiently heated; if the flow rate is large, the heating power may need to be increased; if the flow rate is small, the heating power can be appropriately reduced to avoid energy waste. The flow control unit 13 is also used to replenish the heating energy storage module 22 with water when the water volume of the heating energy storage module 22 is lower than the preset water volume. Specifically, a water replenishment control valve 25 is provided between the flow control unit 13 and the heating energy storage module 22, wherein the water replenishment control valve 25 is used to control the replenishment of water to the heating energy storage module.

[0046] The flow detection unit 12 includes a two-way valve 121 (such as a first two-way valve) and a flow meter 122. The first end of the first two-way valve 121 is connected to the water inlet 11, the second end of the first two-way valve 121 is connected to the flow meter 122, and the flow meter 122 is connected to the heat exchange module 21.

The drainage component 503 may be a drainage pipe, a drainage valve or a drainage port, or a specific drainage container, which is not limited in this application. The above components cooperate to ensure the effective treatment of wastewater in the waterway system of the water supply device.

[0054] The water outlet module 30 includes a second two-way valve 311 (such as called a second two-way valve), a negative temperature coefficient NTC thermistor 312, a one-way valve 313 and a water outlet component 314. The first end of the second two-way valve 311 is connected to the heat exchange module 21 and the on-off valve 132 of the water inlet module 10, and the second end of the second 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,

[0056] The water outlet component 314 is used to output water meeting a preset temperature.

[0057] 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 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.

[0058] The drainage module 50 includes a three-way valve 41, a drainage power component 42 and a wastewater drainage port 43.

[0062] See also Figure 2 As shown, Figure 2 A flow chart of a sterilization control method for a water supply device provided in an embodiment of the present application. The method may include the following steps:

[0063] S1: Obtain sterilization control signal.

[0064] In an embodiment of the present application, the sterilization control signal includes the current bacterial information in the water supply device. Among them, a biosensor is configured inside the water supply device, and the biosensor is communicatively connected to the control module of the water supply device. The biosensor determines the current bacterial information in the water supply device by identifying the enzymes, antibodies, nucleic acids and other biological identification information of the bacteria in the water. The current bacterial information may include: the number and type of bacteria in the water supply device. When the current number of bacteria is greater than or equal to the preset bacterial number value, the biosensor can generate a sterilization control signal based on the current bacterial information. The control module can obtain the sterilization control signal from the biosensor to sterilize the water in the water supply device.

[0065] S2: Responding to the sterilization control signal, obtaining first temperature information of water in the water supply device.

[0066] It is understandable that a temperature sensor is provided in the water pipe of the water supply device, which can be used to detect the temperature of the water in the water supply device. When the heating module heats the water in the water supply device, the operation of the heating module can be controlled by the temperature of the water in the water supply device.

[0067] In the embodiment of the present application, after obtaining the sterilization control signal, the control module can obtain the first temperature information of the water in the water supply device through the temperature sensor in the water supply device in response to the sterilization control signal. The first temperature information may include the temperature of the water in each water pipe in the water supply device.

[0068] S3: Determine sterilization energy consumption information according to the first temperature information and current bacteria information.

[0069] In the embodiment of the present application, the sterilization energy consumption information is used to characterize the energy consumption required by the heating module to sterilize the water corresponding to the first temperature information and the current bacteria information. The control module can predict the sterilization energy consumption information according to the first temperature information and the current bacteria information.

[0070] In a possible embodiment, determining the sterilization energy consumption information according to the first temperature information and the current bacteria information may include:

[0071] Obtain waterway environment information of water supply devices;

[0072] According to the waterway environment information and the current bacteria information, the bacteria quantity prediction process is performed to obtain the bacteria quantity prediction curve;

[0073] Perform water temperature prediction processing according to the waterway environment information and the first temperature information to obtain a water temperature prediction curve;

[0074] Determine the sterilization energy consumption curve based on the bacteria quantity prediction curve and the water temperature prediction curve;

[0075] The sterilization energy consumption curve is determined as the sterilization energy consumption information.

[0076] It should be noted that when sterilizing the water in the water supply device, the water temperature corresponding to the first temperature information needs to be heated. During the heating process, the number of bacteria in the water gradually decreases. As the number of bacteria decreases, the energy consumption of heating can be reduced until the sterilization process is completed. Therefore, it is necessary to predict the change in the number of bacteria and the change in water temperature when the heating module is sterilizing.

[0077] Specifically, the control module first obtains the waterway environment information of the water supply device, which may include: pH value, heavy metal content, dissolved oxygen content and other information of the water in the waterway. Among them, the waterway pipeline of the water supply device may be provided with a detector related to the waterway environment information, such as a pH detector, a metal detector, etc., to detect the waterway environment information of the water supply device. The control module of the water supply device may obtain the waterway environment information of the water supply device from the above detector.

[0078] Then, the control module of the water supply device can determine the bacterial reproduction rate of all bacteria corresponding to the current bacterial information under the waterway environmental information according to the waterway environmental information and the current bacterial information. According to the bacterial reproduction rate of all bacteria corresponding to the current bacterial information under the waterway environmental information, the number of bacteria can be predicted to obtain a bacterial number prediction curve. Optionally, a model corresponding to the above waterway environmental information can be constructed on the simulation software, and the current bacterial information can be added to simulate and obtain a bacterial number prediction curve.

[0079] Furthermore, the control module of the water supply device can determine the water temperature change of the water in the water supply device under normal operation according to the water channel environment information and the first temperature information, thereby obtaining a water temperature prediction curve. Optionally, a model corresponding to the above water channel environment information can be constructed on MATLAB simulation software, and the first temperature information and the historical temperature information of the water channel can be added to simulate and obtain a water temperature prediction curve.

[0080] Furthermore, the control module of the water supply device can predict the sterilization energy consumption of the water supply device according to the bacteria quantity prediction curve and the water temperature prediction curve, determine the sterilization energy consumption curve, and use the sterilization energy consumption curve as the sterilization energy consumption information.

[0081] It can be seen that in the embodiment of the present application, by acquiring the water channel environment information of the water supply device and performing bacteria quantity prediction processing based on the water channel environment information and the current bacteria information, a bacteria quantity prediction curve can be obtained, so that the sterilization energy consumption curve can be determined based on the bacteria quantity prediction curve and the water temperature prediction curve, and the sterilization energy consumption curve can be determined as the sterilization energy consumption information. Therefore, by predicting the changes in the number of bacteria and the water temperature in the water supply device, a suitable sterilization energy consumption curve can be determined, and the sterilization energy consumption curve can be used as the sterilization energy consumption information to control the heating module to sterilize the water in the water supply device, thereby reducing the energy consumption of the sterilization treatment of the water supply device and reducing energy waste.

[0082] In a possible embodiment, determining the sterilization energy consumption curve according to the bacteria quantity prediction curve and the water temperature prediction curve may include:

[0083] Determine the sterilization temperature curve based on the bacterial quantity prediction curve;

[0084] The sterilization temperature curve and the water temperature prediction curve are fused to obtain an intermediate temperature curve;

[0085] The energy consumption conversion process is performed on the intermediate temperature curve to obtain the sterilization energy consumption curve.

[0086] It should be noted that the required sterilization temperature is different at different stages of the change in the number of bacteria. For example, when the number of bacteria grows rapidly, the heating module needs to be heated to a higher sterilization temperature to sterilize the water in the water supply device. When the number of bacteria decreases to less than the preset number of bacteria, the sterilization temperature can be lowered to reduce sterilization energy consumption.

[0087] Specifically, the control module of the water supply device first determines the average change rate and the number of bacteria in multiple time periods according to the bacteria number prediction curve, and then determines multiple sterilization temperatures according to the average change rate and the number of bacteria in multiple time periods corresponding to the bacteria number prediction curve, and multiple time periods correspond to multiple sterilization temperatures one by one. Among them, the mapping relationship between the average change rate, the number of bacteria, and the sterilization temperature can be pre-set according to the actual test results. Then, each sterilization temperature is used as the sterilization temperature at the middle moment of the time period corresponding to the sterilization temperature, and curve fitting is performed on multiple sterilization temperatures to obtain a sterilization temperature curve.

[0088] Furthermore, the control module of the water supply device fuses the sterilization temperature curve and the water temperature prediction curve to predict the temperature of the water supply device during sterilization to obtain an intermediate temperature curve. Optionally, the fusion of the sterilization temperature curve and the water temperature prediction curve can be achieved by simulation on MATLAB simulation software.

[0089] Finally, the control module of the water supply device can determine the output power of the heating module at each moment according to the temperature at each moment in the intermediate temperature curve, and perform energy consumption conversion according to the output power of the heating module at each moment to obtain the sterilization energy consumption corresponding to each moment. Finally, based on the sterilization energy consumption corresponding to each moment, the sterilization energy consumption curve can be determined.

[0090] It can be seen that the sterilization temperature curve can be determined based on the bacteria count prediction curve. By fusing the sterilization temperature curve and the water temperature prediction curve, an intermediate temperature curve can be obtained. Finally, the sterilization energy consumption curve can be obtained by performing energy consumption conversion processing on the intermediate temperature curve. Therefore, by predicting the changes in the number of bacteria and water temperature in the water supply device, the appropriate sterilization energy consumption can be determined to obtain the sterilization energy consumption curve. According to the sterilization energy consumption curve, the heating module can be controlled to sterilize the water in the water supply device, thereby reducing the energy consumption of the sterilization treatment of the water supply device and reducing energy waste.

[0091] S4: Determine sterilization control information according to the sterilization energy consumption information.

[0092] In the embodiment of the present application, the sterilization control information is used to control the heating module to sterilize the water in the water supply device. The sterilization control information may include: heating power information, first water flow rate information of the water in the heating water circuit, second water flow rate information of the water in the heat exchange water circuit in the heat exchanger, and optimal sterilization period information.

[0093] In a possible embodiment, determining the sterilization control information according to the sterilization energy consumption information may include:

[0094] Get the energy consumption price information table;

[0095] Determine the optimal sterilization time period information based on the energy consumption price information table and the sterilization energy consumption curve;

[0096] Determine the actual sterilization energy consumption information based on the optimal sterilization period information and the sterilization energy consumption curve;

[0097] Determine the first water flow rate information of the water in the heating water circuit in the heat exchanger in the heating module, the second water flow rate information of the water in the water exchange water circuit in the heat exchanger, and the heating power information of the heating module according to the actual sterilization energy consumption information;

[0098] The heating power information, the first water flow speed information, the second water flow speed information and the optimal sterilization period information are determined as the sterilization control information.

[0099] It should be noted that the same energy consumption may correspond to different energy prices in different time periods. For example, during peak electricity consumption periods, energy prices are often high to encourage users to reduce energy consumption and ensure energy supply, while during periods of low electricity consumption, energy prices are often low to encourage users to use electricity. Therefore, in order to reduce the sterilization cost of the water supply device, the control module of the water supply device needs to determine the optimal sterilization period information based on the energy price information table and the sterilization energy consumption curve.

[0100] Specifically, the control module of the water supply device first obtains an energy consumption price information table, wherein the energy consumption price information table includes energy consumption price information corresponding to each time period. The control module determines multiple sterilization time periods based on the sterilization energy consumption curve, wherein any one of the multiple sterilization time periods can complete the sterilization treatment of the water in the water supply device. Then, based on the energy consumption price information table, the sterilization cost corresponding to each of the multiple sterilization time periods is determined, and the sterilization time period with the lowest sterilization cost is used as the optimal sterilization time period, and the optimal sterilization time period information corresponding to the optimal sterilization time period is obtained.

[0101] Then, the control module can determine the actual sterilization energy consumption information according to the sterilization energy consumption corresponding to the optimal sterilization period information in the sterilization energy consumption curve.

[0102] It should be noted that the actual sterilization energy consumption information in the water supply device includes: water pump energy consumption information of the heating water circuit in the heat exchanger in the heating module, water pump energy consumption information of the hot water circuit in the heat exchanger, heating energy consumption of the heating module and other energy consumption information.

[0103] Based on this, the control module can determine the first water flow rate information of the water in the heating water circuit in the heat exchanger in the heating module according to the water pump energy consumption information of the heating water circuit in the heat exchanger in the actual sterilization energy consumption information. According to the water pump energy consumption information of the hot water circuit in the heat exchanger, the second water flow rate information of the water in the hot water circuit in the heat exchanger is determined. According to the heating energy consumption and other energy consumption information of the heating module, the heating power information of the heating module is determined.

[0104] Finally, the control module of the water supply device can determine the heating power information, the first water flow rate information, the second water flow rate information and the optimal sterilization period information as the sterilization control information to control the heating power of the heating module, the first water flow rate of the water in the heating water circuit in the heat exchanger, and the second water flow rate of the water in the hot water circuit in the heat exchanger.

[0105] It can be seen that in the embodiment of the present application, the energy consumption price information table can be obtained, and the optimal sterilization period information can be determined according to the energy consumption price information table and the sterilization energy consumption curve, so as to determine the actual sterilization energy consumption information according to the optimal sterilization period information and the sterilization energy consumption curve, and then determine the first water flow rate information of the water in the heating water circuit in the heat exchanger in the heating module, the second water flow rate information of the water in the water exchange water circuit in the heat exchanger and the heating power information of the heating module according to the actual sterilization energy consumption information. Finally, the heating power information, the first water flow rate information, the second water flow rate information and the optimal sterilization period information are determined as the sterilization control information. Thus, the heating module can be controlled to perform sterilization treatment in the optimal sterilization period to reduce the sterilization treatment cost of the water supply device, and the heating power of the heating module, the first water flow rate of the water in the heating water circuit, and the second water flow rate of the water in the water exchange water circuit can be accurately controlled according to the sterilization control information, thereby improving the accuracy of the sterilization treatment control.

[0106] In another possible embodiment, determining the sterilization control information according to the sterilization energy consumption information may include:

[0107] Extract sterilization control information to generate a model;

[0108] The sterilization control information generation model is used to calculate the sterilization control information based on the sterilization energy consumption information.

[0109] The sterilization control information generation model can be obtained by training the preset sterilization control information generation model through historical sterilization energy consumption information and historical sterilization control information. The preset sterilization control information generation model can be a deep learning model, for example, a convolutional neural network model (CNN), a recurrent neural network layer (RNN), and the like.

[0110] Specifically, firstly, the preset sterilization control information generation model is trained by taking the historical sterilization energy consumption information as the input of the preset sterilization control information generation model and the historical sterilization control information as the output of the preset sterilization control information generation model, so as to obtain a candidate sterilization control information generation model. Then, a test data set (test data used to test the data) is obtained to test the candidate sterilization control information generation model to obtain the prediction accuracy of the candidate sterilization control information generation model. When the prediction accuracy is greater than or equal to the preset accuracy, the candidate sterilization control information generation model is used as the sterilization control information generation model; otherwise, new historical sterilization energy consumption information and new historical sterilization control information are continuously obtained to train the candidate sterilization control information generation model until a sterilization control information generation model with a prediction accuracy greater than or equal to the preset accuracy is obtained.

[0111] Based on this, the control module of the water supply device will extract the sterilization control information generation model, and input the sterilization energy consumption information into the sterilization control information generation model, and calculate the sterilization control information through the sterilization control information generation model.

[0112] It can be seen that by training the preset sterilization control information generation model, a sterilization control information generation model is obtained. The control module can extract the sterilization control information generation model, and use the sterilization control information generation model to calculate the sterilization control information according to the sterilization energy consumption information. In this way, the calculated sterilization control information is related to the sterilization energy consumption information, which can reduce energy waste in the sterilization process.

[0113] S5: According to the sterilization control information, control the water supply device to perform sterilization.

[0114] In the embodiment of the present application, after determining the sterilization control information, the control module of the water supply device will control the heating module to work with the heating power information corresponding to the heating module according to the sterilization control information, and control the water pump of the heating water circuit in the heat exchanger to work according to the first water flow rate information of the water in the heating water circuit in the heat exchanger, and control the water pump of the hot water circuit in the heat exchanger to work according to the second water flow rate information of the water in the hot water circuit in the heat exchanger. Based on this, the sterilization treatment of the water in the water supply device can be achieved.

[0115] It can be seen that in the scheme implemented by the sterilization control method, device, water supply device and storage medium of the above-mentioned water supply device, by obtaining the sterilization control signal, the first temperature information of the water in the water supply device can be obtained in response to the sterilization control signal, and then the sterilization energy consumption information is determined according to the first temperature information and the current bacteria information, so that the sterilization control information can be determined according to the sterilization energy consumption information, and finally, according to the sterilization control information, the heating module can be controlled to sterilize the water in the water supply device. Based on this, the water supply device can be controlled to sterilize in time based on the current bacteria information in the water supply device, and the sterilization energy consumption information can be determined according to the first temperature information of the water in the water supply device and the current bacteria information, and the corresponding sterilization control information can be determined according to the sterilization energy consumption information, so as to control the heating module to sterilize the water in the water supply device, thereby reducing the sterilization energy consumption of the water supply device and reducing energy waste.

[0116] In a possible embodiment, after controlling the water supply device to perform sterilization according to the sterilization control information, the method may further include:

[0117] Obtaining bacterial information after sterilization of water supply equipment;

[0118] If the bacteria count in the bacteria information is higher than the preset bacteria count value, the secondary sterilization temperature information is determined;

[0119] Determine secondary sterilization control information according to secondary sterilization temperature information;

[0120] The secondary sterilization control information is used to control the heating module to perform secondary sterilization on the water in the water supply device.

[0121] It should be noted that since the change in the number of bacteria and the change in water temperature in the water supply device are both predicted values, after the water supply device is controlled to perform sterilization according to the sterilization control information, the number of bacteria in the water supply device may still be higher than the preset number of bacteria. At this time, the water in the water supply device needs to be sterilized again to ensure the safety of the water quality in the water supply device. The secondary sterilization temperature information can be a preset sterilization temperature value, etc.

[0122] Specifically, the control module of the water supply device can obtain the bacterial information of the water supply device after sterilization through the biosensor in the water supply device, and the bacterial information includes information such as the number of bacteria and the type of bacteria.

[0123] If the bacteria count in the bacteria information is less than or equal to the preset bacteria count value, it means that the sterilization process is completed.

[0124] If the number of bacteria in the bacteria information is higher than the preset bacteria number value, it means that the heating module has not completed the sterilization process of the water in the water supply device, and the control module of the water supply device can obtain the second temperature information of the water in the water supply device through the temperature sensor in the water supply device. The secondary sterilization energy consumption information is determined according to the bacteria information and the second temperature information, and the secondary sterilization temperature information is determined according to the secondary sterilization energy consumption information. Finally, according to the secondary sterilization control information, the heating module is controlled to perform secondary sterilization on the water in the water supply device.

[0125] It should be noted that the processing method of determining the secondary sterilization energy consumption information according to the bacterial information and the second temperature information is similar to the processing method of determining the sterilization energy consumption information according to the first temperature information and the current bacterial information; the processing method of determining the secondary sterilization temperature information according to the secondary sterilization energy consumption information is similar to the processing method of determining the sterilization control information according to the sterilization energy consumption information; controlling the heating module to perform secondary sterilization on the water in the water supply device according to the secondary sterilization control information is similar to controlling the heating module to sterilize the water in the water supply device according to the sterilization control information, and they will not be repeated here.

[0126] Therefore, by obtaining the bacteria information after the sterilization treatment, the secondary sterilization temperature information can be determined when the bacteria count is higher than the preset bacteria count value, and the secondary sterilization control information can be determined according to the secondary sterilization temperature information. Finally, the secondary sterilization control information is used to control the heating module to perform secondary sterilization treatment on the water in the water supply device. Through secondary sterilization, the sterilization effect of the water supply device can be improved and the water quality safety of the water supply device can be guaranteed.
