[0047] Example 1

[0048] This application provides a method for determining the temperature of a water heater. Figure 1 This is a schematic diagram illustrating the implementation process of a method for determining the temperature of a water heater provided in an embodiment of this application, as shown below. Figure 1 As shown, the method includes:

[0049] Step S101: Obtain the user's water consumption in the current time period, the first temperature and the second temperature corresponding to the water consumption, and the third temperature of the tap water, wherein the first temperature is the temperature of the water at a preset position in the water tank of the water heater before the water consumption is used, and the second temperature is the temperature of the water at the preset position after the water consumption is used.

[0050] The electronic device allows the user to input water consumption for the current time period, a first temperature, a second temperature corresponding to the water consumption, and a third temperature of the tap water using an input device. In this embodiment, the input device may include a mouse, a keyboard, a storage device, etc.

[0051] In this embodiment, the duration of the time period can be configured; for example, a time period can be configured to be 5 minutes or 10 minutes. In this embodiment, the preset position can be set; for example, it can be the middle position of the water tank.

[0052] In some embodiments, the electronic device may be connected to a detection device, which is used to check the third temperature of the tap water, thereby enabling the electronic device to obtain the third temperature of the tap water.

[0053] In this embodiment, the water consumption can be either actual or predicted. In this embodiment, the electronic device can determine the actual water consumption using a first temperature and a second temperature. In some embodiments, the electronic device can determine the predicted water consumption using user water consumption behavior information from at least one historical time period, and then determine the first and second temperatures based on the water consumption.

[0054] Step S102: Calculate the set temperature of the water heater for the current time period based on the water consumption, the first temperature, the second temperature, and the third temperature.

[0055] In this embodiment of the application, the set temperature of the water heater for the current time period can be calculated using a formula based on the water consumption, the first temperature, the second temperature, and the third temperature. The formula is:

[0056]

[0057] Among them, T set To set the temperature, V consume ρ represents the water consumption. water T is the density of water. consume The first temperature, T tap T represents the temperature of tap water. now For the second temperature, V water Let K be the volume of the water tank, and K be a coefficient.

[0058] In this embodiment of the application, K can be 4.19.

[0059] In this embodiment of the application, the volume of the water tank, the density of the water, and the coefficient are all preset. After obtaining the water consumption, the first temperature, the second temperature, and the third temperature, the water consumption, the first temperature, the second temperature, and the third temperature can be substituted into the calculation formula to determine the set temperature.

[0060] In some embodiments, step S101 can be implemented by the following steps:

[0061] Step S1: Obtain the first temperature and the second temperature.

[0062] In this embodiment of the application, the first temperature and the second temperature are directly detected. In this embodiment of the application, the water consumption is the actual water consumption. The detection device can directly detect the first temperature and the second temperature.

[0063] Step S2: Determine temperature change information based on the first temperature and the second temperature.

[0064] In this embodiment, the temperature change information can be determined by subtracting the second temperature from the first temperature.

[0065] Step S3: Determine the user's water consumption in the current time period based on the temperature change information and the pre-established water consumption judgment model, wherein the water consumption judgment model includes the correspondence between temperature change information and water consumption.

[0066] In this embodiment of the application, since the water consumption judgment model includes the correspondence between temperature change information and water consumption, after obtaining the temperature change information, the user's water consumption in the current time period can be determined based on the correspondence.

[0067] The third temperature can be directly measured, thereby enabling the electronic device to obtain the water consumption, the first temperature, the second temperature, and the third temperature.

[0068] In some embodiments, step S101 can be implemented by the following steps:

[0069] Step S4: Obtain user water usage behavior information for at least one historical time period.

[0070] In this embodiment, the user water usage behavior information may include: water usage time, water usage volume, etc. In this embodiment, the time period can be configured.

[0071] Step S5: Input the water usage behavior information into a pre-established water usage prediction model to determine the user's water usage in the current time period, wherein the current time period is the first time period after the historical time period.

[0072] In this embodiment, the pre-established water consumption prediction model can be a trained neural network model. An initial neural network model can be trained using a sample dataset to obtain the pre-established water consumption prediction model. In this embodiment, a sample dataset can be obtained, where each sample data point includes: sample water consumption behavior information within at least one time period and water consumption in the next time period following the at least one time period. The sample water consumption behavior information is used as input to the neural network model, and the set temperature in the next time period following the at least one time period is used as the output of the neural network model. The neural network model is then trained to obtain the water consumption prediction model. In this embodiment, the water consumption in the next time period following the at least one time period can be predicted based on expert experience.

[0073] In this embodiment of the application, after obtaining the user's water usage behavior information for at least one historical time period, the water usage for the current time period can be determined by the water usage prediction model.

[0074] In some embodiments, after step S5, the method further includes:

[0075] Step S6: Determine the temperature change information based on the water consumption and water consumption judgment model, wherein the water consumption judgment model includes: the correspondence between temperature change information and water consumption;

[0076] Step S7: Determine the second temperature based on the temperature change information and the first temperature.

[0077] In this embodiment of the application, since the water consumption for the current time period is predicted, but the first temperature can be directly detected before the water consumption is used, the temperature after the water consumption can be predicted based on the temperature change information and the first temperature.

[0078] In some embodiments, prior to step S3 or step S7, the method further includes: establishing a water consumption judgment model. Figure 2 This is a schematic diagram illustrating the implementation process of a method for establishing a water consumption judgment model provided in an embodiment of this application. Figure 2 As shown, it includes:

[0079] Step S21: Obtain the appearance parameters of the water tank.

[0080] In this embodiment of the application, the appearance parameters of the water tank can be obtained through user input. The appearance parameters may include the length, width, height, radius, etc. of the water tank.

[0081] Step S22: Establish a simulation model of the water tank based on the appearance parameters.

[0082] In this embodiment of the application, the simulation mode can be a 3D simulation model of a water tank.

[0083] Step S23: Divide the simulation model into a mesh.

[0084] In this embodiment of the application, the internal computational region of the simulation model can be divided into a mesh based on the finite element analysis method.

[0085] Step S24: Determine the fluid calculation model of the simulation model and the setting conditions of the simulation model.

[0086] In this embodiment of the application, user input information can be obtained to determine the fluid calculation model of the simulation model and the setting conditions of the simulation model.

[0087] In this embodiment of the application, the fluid computation model may include any one of the following: the standard k-ε model, the RNG k-ε model, and the Reliable k-ε model, preferably the RNG k-ε model.

[0088] In this embodiment of the application, the setting conditions of the simulation model may include: initial water temperature, inlet water flow rate, water tank material, etc.

[0089] Step S25: Based on the fluid calculation model and the set conditions, the simulation model is simulated and calculated with different inlet flow rates and different flow durations to obtain the correspondence between different inlet flow rates, different flow durations and the temperature change information of water at different positions in the water tank.

[0090] In this embodiment, simulation calculations with different inlet flow rates and different flow durations can yield water temperature change information at different locations. This allows the establishment of a correspondence between different inlet flow rates, different flow durations, and the temperature change information of water at different locations in the tank.

[0091] Step 26: Based on the correspondence between different inlet flow rates, different flow durations and water temperature changes at different locations in the water tank, determine the correspondence between different water consumption and water temperature changes at different locations in the water tank, so as to obtain a water consumption judgment model.

[0092] In this embodiment of the application, the correspondence between different inlet flow rates, different flow durations and water temperature changes at different locations in the water tank can be converted to obtain the correspondence between different water consumption and water temperature changes at different locations in the water tank, so as to obtain a water consumption judgment model.

[0093] For example, taking the middle of the water tank as a designated location, and the initial water temperature as a℃, with a flow rate of vm / s for Tmin, the water temperature at the designated location will change accordingly, let's say to b℃. The total water consumption Q in this case is calculated as follows: Q = vT. Therefore, we can denote the water consumption as Q when the initial water temperature at the middle of the tank is a, and the final water temperature is b. By saving this data and performing multiple simulations, we can establish the correspondence between water temperature changes and water consumption, and store this correspondence in a database.

[0094] In some embodiments, after step S102, the method further includes:

[0095] The set temperature is sent to the water heater so that the water heater can modify the set temperature.

[0096] This application provides a method for determining the temperature of a water heater. Based on a physical model and simulation software, a mathematical model is established to analyze the temperature change pattern of the water tank when a user uses water. Combined with deep neural network technology, the method judges the user's water usage behavior by analyzing the temperature change of the water tank and then calculates the optimal set temperature for the multi-functional water heater based on the user's water usage behavior. This method saves energy consumption while meeting user requirements, improving the user experience, and enhancing the intelligence of the method.
