[0053] Step S101, obtaining the set temperature of the water heater and the current inlet water temperature of the water at the water inlet.

[0054] In the embodiments of the present application, the electronic device can obtain the current temperature of the water at the water inlet through a temperature sensor. In some embodiments, the user can input the set temperature of the water heater and the current inlet water temperature of the water at the water inlet through an APP, so that the electronic device obtains the set temperature of the water heater and the current inlet water temperature of the water at the water inlet. The current inlet water temperature can be the temperature of tap water or the ambient temperature.

[0055] In the embodiments of the present application, the water heater may be a gas water heater, a wall-mounted boiler water heater, etc.

[0056] Step S102: Determine the actual set temperature at each operation moment based on the set temperature, the current inlet water temperature, and the heat transfer parameter, where the heat transfer parameter is used to characterize the heat dissipation condition of the pipeline between the water heater and the water usage point.

[0057] In the embodiments of the present application, the heat transfer parameter includes: the inlet water temperature during the test, the set temperature during the test, and the consumption time from when the water heater is turned on during the test to when the water usage point reaches the set temperature during the test.

[0059] Step S1021: Input the set temperature, the current inlet water temperature, and the heat transfer parameter into a pre-established first calculation model to determine the actual set temperature at each operation moment, where the first calculation model is:

[0060] T set_t = f(T set , t, T 进 , T 进0 , T 设0 , t0);

[0061] Wherein, T set_t is the actual set temperature, T set is the set temperature, t is the time, T 进 is the current inlet water temperature, T 进0 is the inlet water temperature during the test, T 设0 is the set temperature during the test, t0 is the consumption time, wherein, the T set_t is inversely proportional to the T 进 , and T set_t is inversely proportional to t.

[0062] In the embodiments of the present application, the parameters of the first calculation model can be obtained by fitting based on experimental data.

[0063] In the embodiments of the present application, before step S1021, the method further includes:

[0064] Step S1: Obtain the inlet water temperature during the test and the set temperature during the test.

[0065] In the embodiments of the present application, the electronic device can obtain the user's setting to determine the set temperature during the test. The electronic device can be communicatively connected to the sensor and obtain the inlet water temperature during the test through the temperature sensor.

[0066] Step S2, when the water usage point is turned on, control the water heater to operate based on the set temperature during the test, and start timing.

[0067] In the embodiment of the present application, during the test, the user can open the faucet at the water usage point to turn on the water usage point.

[0068] In the embodiment of the present application, when controlling the water heater to operate based on the set temperature during the test, first, the water pump of the water heater starts. After the water pump starts, water enters from the water inlet. After meeting the combustion conditions, combustion is started. The water heater can control the opening degree of the gas inlet valve based on the target set temperature, thereby controlling the output of gas and thus controlling combustion. In the embodiment of the present application, after the test is started, timing is performed.

[0069] Step S3, obtain the test temperature of the water usage point.

[0070] In the embodiment of the present application, the user can set a temperature sensor at the water usage point to detect the outlet water temperature of the water usage point. The user can input the test temperature into an electronic device, so that the electronic device obtains the test temperature of the water usage point.

[0071] Step S4, when the test temperature reaches the set temperature during the test, record the elapsed time when the test temperature of the water usage point reaches the set temperature during the test.

[0072] In the embodiment of the present application, if the test temperature does not reach the set temperature during the test, continue heating.

[0073] Step S5, and record the elapsed time, the inlet water temperature during the test, and the set temperature during the test.

[0074] In the embodiment of the present application, the elapsed time, the inlet water temperature during the test, and the set temperature during the test can be obtained through testing, and these parameters can characterize the heat dissipation situation of the pipeline between the water heater and the water usage point.

[0075] Step S103, control the water heater to heat based on the actual set temperature at each operating moment, so that the outlet water temperature of the water usage point is maintained at the set temperature.

[0076] In the embodiment of the present application, by dynamically adjusting the actual set temperature, the outlet water temperature of the water usage point can be maintained at the set temperature.

[0077] Figure 3 It is a schematic diagram of the actual set temperature of a water heater provided by the embodiment of the present application, as Figure 3As shown in the figure, in the figure, the line T - water - t is a straight line in the middle, which is the set temperature, that is, the temperature that the user wants to use. T_set - t is the actual set temperature, and T_pipe - t is the water pipe temperature. The abscissa in the figure is time, and the ordinate is temperature. It can be seen that through the actual set temperature control as in Figure 3 The water temperature can be kept constant, and as the temperature of the pipeline rises, the actual set temperature gradually decreases until the actual set temperature is the set temperature.

[0078] A control method provided by the present application includes obtaining the set temperature of the water heater and the current inlet water temperature of the water at the water inlet; determining the actual set temperature at each operating moment based on the set temperature, the current inlet water temperature, and the heat transfer parameter, where the heat transfer parameter is used to characterize the heat dissipation situation of the pipeline between the water heater and the water usage point; and controlling the water heater to heat based on the actual set temperature at each operating moment, so that the outlet water temperature at the water usage point can be maintained at the set temperature.

[0079] In some embodiments, after step S103, the method further includes:

[0080] Step S104, after the water heater stops heating, determine the duration of the stop heating;

[0081] Step S105, determine the actual set temperature based on the duration of the stop heating, the set temperature, the current inlet water temperature, the actual outlet water temperature corresponding to the duration of the stop heating, and the heat transfer parameter.

[0082] In the embodiments of the present application, step S105 can be implemented through the following steps:

[0083] Step S1051, determine whether the duration of the stop heating is greater than a preset duration threshold. Wherein, when the duration of the stop heating is greater than the preset duration, the actual outlet water temperature value drops to the current inlet water temperature.

[0084] In the embodiments of the present application, the preset duration threshold can be obtained through experiments. That is, the actual outlet water temperature value drops to the current inlet water temperature.

[0085] Step S1052, when the duration of the stop heating is greater than the preset duration threshold, calculate the actual set temperature based on the set temperature, the current inlet water temperature, and the heat transfer parameter using a second calculation model, where the second calculation model is:

[0086] T set_t =f(T set ,0,T 进 ,T 进0 ,T 设0 ,t0).

[0087] In the embodiments of the present application, the T set_t is the maximum temperature setting value of the water heater.

[0088] In some embodiments, the method further includes:

[0089] Step S1053, when the duration of stopping heating is less than a preset duration threshold, calculate the actual set temperature based on the set temperature, the current inlet water temperature, and the heat transfer parameter by using a third calculation model, where the third calculation model is:

[0090] T set_t = f(T set , t 停 , T 进 , T 进0 , T 设0 , t0, T set_t1 );

[0091] wherein, T set_t1 is the actual outlet water temperature corresponding to the duration of stopping heating.

[0092] Figure 4 FIG. is a schematic diagram of the actual set temperature of a water heater provided by the embodiments of the present application. As Figure 4 shown, the abscissa in the figure is time and the ordinate is temperature. In the case of no combustion, the temperature of the pipeline gradually decreases, while the actual set temperature gradually increases. When the temperature of the pipeline decreases to the tap water temperature, the actual set temperature reaches the maximum temperature setting value.

[0093] A control method provided by the embodiments of the present application can adjust the actual set temperature of the water heater according to the duration of stopping heating after stopping heating, and can control the outlet water temperature when starting next time, so that the water temperature at the water usage point is consistent with the water temperature at the outlet point, and solves the problem that the water temperature at the water usage point does not match the water temperature at the outlet point due to pipeline heat dissipation.
