[0067] The loop module 700 includes: a seventh control valve 17, a second pumping component 24, and a waste water discharge pipe 72. It can be understood that the second pumping component 24 can use a water pump. The second pumping component 24 can also be replaced by a water bladder.

The heat in the hot water is exchanged to the first pipe of the heat exchanger 32 and then becomes cold, and then flows back to the heat storage tank 41 from the second end of the second pipe of the heat exchanger 32.

[0073] The heat carried by the second pipe of the heat exchanger 32 is exchanged to the first pipe of the heat exchanger 32 to increase the temperature of the water flowing through the first pipe of the heat exchanger 32, thereby realizing heat exchange.

Whether the cleaning agent in the cleaning agent storage box is dosed is controlled by controlling the on-off of the dosing control valve, and the dosing amount of the cleaning agent in the cleaning agent storage box is controlled by controlling the conduction duration of the dosing control valve. It can be understood that the number of dosing control valves is multiple, so that the cleaning agent can be dosed separately for each module and the water inlet module.

[0083] Optionally, the control module 600 includes: a memory, a processor, and a computer program stored in the memory and executable on the processor.

[0092] Specifically, the user can trigger the antifreeze signal through the button on the water supply device, the user can also input the antifreeze signal through the touch screen on the water supply device, the user can also input the antifreeze signal through the client communicatively connected to the water supply device, and the user can also send the antifreeze signal to the server through a third-party application (such as an application system of the Internet of Things), and the server will send the antifreeze signal to the program file implementing the present application.

[0093] It can be understood that it can also be that the program file implementing the present application actively generates an antifreeze signal according to a preset condition. For example, the antifreeze signal is actively triggered at a preset time interval.

[0094] The client can include but is not limited to: various personal computers, laptop computers, smart phones, tablet computers, and portable wearable devices.

[0095] The server can be a server.

[0096] S2: In response to the antifreeze signal, obtain a target antifreeze plan;

[0097] Specifically, when receiving the antifreeze signal, the target antifreeze plan can be obtained from a preset storage space, or it can also be that the program file implementing the present application determines the target antifreeze plan according to a preset plan determination method.

Then, according to this solution, the heating module is precisely controlled to heat and part or all of the return water circuit is conducted, realizing efficient water circuit anti-freezing based on hot water circulation. Thus, not only is it ensured that the water supply device can operate stably in a cold environment, continuously provide hot water for users, avoid water supply device failures and usage interruptions caused by water circuit freezing, but also the user experience is greatly improved. At the same time, through the target anti-freezing solution, intelligent control is achieved, effectively reducing energy consumption and improving resource utilization efficiency.

[0102] Please refer to Figure 3 As shown, in one embodiment, the method further includes:

[0103] S41: Obtain the temperature data to be processed and the historical usage data of the water supply device at a first time interval. The temperature data to be processed includes: ambient temperature data and / or water circuit temperature data;

[0104] The first time interval is a preset interval period duration.

[0105] The ambient temperature data is the temperature data of the environment where the water supply device is located.

[0106] The water circuit temperature data is the temperature data of the water circuit of the water supply device. By installing temperature sensors in the water supply device, the temperature of the water circuit of the water supply device is detected by the temperature sensors. Therefore, the temperature detected by each temperature sensor can be obtained at the first time interval as the water circuit temperature data.

[0107] Optionally, the historical usage data is the usage data of the water supply device within a preset duration.

[0108] The historical usage data of the water supply device can be obtained from a preset storage space.

[0110] The preset anti-freezing solution library is a preset anti-freezing solution library. The anti-freezing solution library describes the corresponding relationship between temperature data and anti-freezing solutions. The anti-freezing solution describes the range of the water circuit that needs anti-freezing treatment and the specific control data for anti-freezing treatment.

[0111] Specifically, an anti-freezing solution corresponding to the temperature data to be processed is screened out from the preset anti-freezing solution library, and the screened-out anti-freezing solution is used as the initial anti-freezing solution.

[0112] S43: Generate solution adjustment data according to the historical usage data;

[0113] Optionally, according to the historical usage data, a look-up table method is used to determine the scheme adjustment data.

[0114] Optionally, the historical usage data is input into a pre-trained adjustment data prediction model for classification prediction, the vector element with the largest value is selected from the predicted vectors, and the classification category corresponding to the selected vector element is used as the scheme adjustment data.

[0115] Optionally, based on a regular expression, index values are extracted from the historical usage data, and a look-up table method is used to determine the scheme adjustment data according to the extracted index values.

[0116] The pre-trained adjustment data prediction model is a pre-trained multi-classification model. The model structure and model training method of the adjustment data prediction model can be selected from the prior art and will not be elaborated here.

[0117] S44: According to the scheme adjustment data, the initial anti-freezing scheme is adjusted to obtain a stage anti-freezing scheme, where the target anti-freezing scheme is a scheme determined based on the stage anti-freezing scheme.

[0118] Specifically, according to the scheme adjustment data, the parameter values of the specific control data in the initial anti-freezing scheme are updated, and the updated initial anti-freezing scheme is used as the stage anti-freezing scheme, where the update operation can be any one of replacement, addition, and subtraction.

[0119] It can be understood that the stage anti-freezing scheme can be directly used as the target anti-freezing scheme, or the target anti-freezing scheme can be generated based on the stage anti-freezing scheme.

[0120] In this embodiment, according to the historical usage data, scheme adjustment data is generated to update the anti-freezing scheme screened from the preset anti-freezing scheme library according to the to-be-processed temperature data, so as to determine the stage anti-freezing scheme, thereby making the determined stage anti-freezing scheme meet the requirements of the to-be-processed temperature data and the water supply device usage, improving the accuracy of the determined stage anti-freezing scheme, improving the intelligence of this application, and improving the anti-freezing effect.

[0121] In one embodiment, the step of obtaining the target anti-freezing scheme in response to the anti-freezing signal includes:

[0122] S21: In response to the anti-freezing signal, obtain the stage anti-freezing scheme as the to-be-processed scheme;

[0123] Specifically, when the anti-freezing signal is received, obtain the stage anti-freezing scheme, and use the obtained stage anti-freezing scheme as the to-be-processed scheme.

[0124] S22: Obtain the current ambient temperature and the data to be analyzed for use, where the data to be analyzed for use is the usage data of the water supply device within a preset time window;

[0125] The current ambient temperature is the temperature of the current environment.

[0126] Specifically, the current ambient temperature can be obtained from a third party, or a temperature sensor can be installed on the water supply device to detect the temperature of the external environment of the water supply device.

[0127] The current time can be used as the end time of the preset time window, and the usage data of the water supply device within the preset time window can be obtained from the preset storage space, and the obtained usage data is used as the data to be analyzed for use.

[0128] S23: Fine-tune the to-be-processed solution according to the current ambient temperature and the data to be analyzed for use to obtain the target anti-freezing solution.

[0129] Optionally, using the look-up table method, determine the fine-tuning data according to the current ambient temperature and the data to be analyzed for use, and use the fine-tuning data to fine-tune the parameter values of the specific control data in the to-be-processed solution, and use the fine-tuned to-be-processed solution as the target anti-freezing solution, where the fine-tuning operation can be any one of addition, subtraction, and multiplication.

[0130] It can be understood that the to-be-processed solution is a solution for a first duration, and what is fine-tuned for the to-be-processed solution according to the current ambient temperature and the data to be analyzed for use is a part (that is, a sub-solution) of the to-be-processed solution. Because the to-be-processed solution is a solution for a first duration, by finely adjusting the part (that is, the sub-solution), it can better adapt to the specific current ambient temperature and the data to be analyzed for use without affecting the overall framework, making the solution more targeted and able to respond more precisely to different situations. This can ensure more effective anti-freezing measures in a specific environment, such as within different temperature ranges, and guarantee the stable operation of the water supply device. At the same time, by fine-tuning the part, large-scale changes to the entire solution can be avoided, reducing the complexity and risk of adjustment, making the adjustment process more efficient and reliable. Moreover, this targeted fine-tuning can further optimize resource allocation according to the actual usage data, reduce unnecessary energy waste while ensuring the anti-freezing effect, improve energy utilization efficiency, and thus achieve a more energy-saving and environmentally friendly operation.

[0131] The method of fine-tuning the to-be-processed solution according to the current ambient temperature and the data to be analyzed for use in this embodiment can make the target anti-freezing solution more accurately adapt to the actual situation. It can make timely adjustments according to the real-time changes in the ambient temperature, ensuring that the most suitable anti-freezing strategy can be provided under different cold degrees, effectively avoiding the occurrence of over-protection or under-protection. At the same time, by combining the data to be analyzed for use, it can take into account the actual usage habits and states of the water supply device, making the anti-freezing solution more targeted and personalized, and further improving the reliability and stability of the anti-freezing effect. This not only enhances the adaptability of the water supply device in various complex environments, ensures its continuous and stable operation, but also reasonably optimizes the resource allocation while achieving effective anti-freezing, reduces unnecessary energy consumption, and achieves the purpose of energy conservation and efficiency improvement.

[0136] S232: Perform future temperature trend prediction according to the weather forecast data and the current ambient temperature to obtain future temperature data;

[0137] Optionally, based on a preset temperature adjustment formula, adjust the temperature in the weather forecast data according to the humidity of the weather forecast data and the current ambient temperature to obtain future temperature data.

[0138] The temperature adjustment formula is a formula obtained by fitting historical weather forecast data and actual temperature data using a data fitting method. For example, the data fitting method uses linear fitting.

[0139] Optionally, input the weather forecast data and the current ambient temperature into a pre-trained temperature prediction model for future temperature trend prediction to obtain future temperature data.

[0140] The pre-trained temperature prediction model is a model pre-trained based on a time series model (such as, ARIMA). ARIMA, that is, the autoregressive integrated moving average model.

[0143] In this embodiment, the to-be-processed solution is fine-tuned according to the future temperature data and the data obtained by predicting the future temperature trend based on the weather forecast data and the current ambient temperature, so that the target anti-freezing solution can conform to the temperature trend without frequently adjusting the entire anti-freezing solution, and the adaptability of the target anti-freezing solution is improved while saving computing resources.

[0147] S52: Perform anti-freezing judgment on key parts according to the water path temperature distribution data and the preset target anti-freezing conditions to obtain a judgment result;

[0148] Optionally, a regular expression is used to perform anti-freezing judgment on key parts according to the water path temperature distribution data and the preset target anti-freezing conditions; if the water path temperature distribution data conforms to the component anti-freezing conditions in the preset target anti-freezing conditions, the value corresponding to the component in the judgment result (that is, the sub-result) corresponding to the component anti-freezing conditions is set to yes; if the water path temperature distribution data does not conform to the component anti-freezing conditions in the preset target anti-freezing conditions, the value corresponding to the component in the judgment result (that is, the sub-result) corresponding to the component anti-freezing conditions is set to no.

[0149] Optionally, the water path temperature distribution data and the preset target anti-freezing conditions are spliced and input into a pre-trained anti-freezing judgment model for classification prediction, the maximum value of the key components is found from the predicted vector, and the classification category corresponding to the vector element corresponding to the maximum value is used as the sub-result corresponding to the key component.

[0151] S53: Generate a partial anti-freezing plan based on the judgment result, the waterway temperature distribution data, and the target anti-freezing plan.

[0152] Specifically, screen out the sub-plans in the target anti-freezing plan where the sub-result in the judgment result is "yes". According to the waterway temperature distribution data, use the look-up table method to obtain local data, update the sub-plans based on the local data, and use the updated sub-plans as the partial anti-freezing plan. Among them, the update operation can be any one of replacement, addition, and subtraction.
