The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0043] refer to Figure 1 , Figure 1 This is a flowchart of an air conditioning water tank temperature control method according to an embodiment of the present invention. The air conditioning water tank temperature control method includes, but is not limited to, the following steps:

[0044] Obtain the ambient temperature;

[0045] The target temperature of the water tank is determined based on the ambient temperature and the preset information of the heating curve. The preset information of the heating curve includes the target indoor temperature, the starting temperature of the curve, and the maximum temperature of the curve, wherein the starting temperature of the curve is less than the maximum temperature of the curve.

[0046] The air conditioning water tank is heated according to the target temperature of the water tank.

[0047] refer to Figures 1 to 5The preset information for the heating curve includes the target indoor temperature, the curve's starting temperature, and the curve's maximum temperature. Using the pre-defined constraint formula for the target water tank temperature, along with the target indoor temperature, the curve's starting temperature, and the curve's maximum temperature, a curve equation expressing the target water tank temperature can be constructed. Here, the ambient temperature is the independent variable, the target indoor temperature, the curve's starting temperature, and the curve's maximum temperature are the constraint values ​​for these three independent variables, and the dependent variable is the target water tank temperature to be obtained. The maximum temperature on the curve is the maximum temperature in the preset heating curve information, and the curve's starting temperature is the minimum temperature in the preset heating curve information. These two preset temperature parameters are used to control the slope of the curve; the target indoor temperature is used to control the curve's shift.

[0048] Before heating the water tank, the ambient temperature is acquired. Then, based on the ambient temperature and a preset heating curve, the target temperature for the water tank is determined. Once the target temperature is determined, the air conditioning water tank is heated accordingly. This effectively achieves the effect of dynamically adjusting the user's desired temperature based on the ambient temperature. Furthermore, by automatically acquiring the ambient temperature and using the preset heating curve to dynamically control the water temperature and obtain the target temperature for the water tank, comfortable temperatures are provided for different scenarios, maximizing the satisfaction of users' heating needs and improving the user experience.

[0049] It should be noted that this embodiment does not limit the curve's initial temperature and maximum temperature. As long as the curve's initial temperature is less than the curve's maximum temperature, it can be set reasonably.

[0050] In some embodiments, the preset heating curve information is obtained through the following steps:

[0051] Obtain the curve setting parameters, which include the indoor room temperature setting value, the initial temperature setting value, and the maximum temperature setting value;

[0052] The heating curve preset information is generated based on the parameters set in the curve.

[0053] Multiple sets of curve setting parameters can be configured, each corresponding to a different operating mode of the air conditioner. Taking water tank heating as an example: light heating mode, medium heating mode, and heavy heating mode can be set. In light heating mode, the heating demand is lower, so the indoor room temperature setpoint, initial temperature setpoint, and maximum temperature setpoint can be set to smaller values. This results in a lower initial temperature change point and a gentler slope in the heating curve, leading to a smoother temperature increase. Medium heating mode and heavy heating mode allow for relatively larger curve setting parameter values, thereby altering the initial temperature change point and the rate of temperature rise.

[0054] In some embodiments, the constraint formula for the target temperature of the water tank is:

[0055] T = t3 + (t4 - t3) / 35 * (t1 - t2);

[0056] In the formula, T is the target temperature of the water tank, t1 is the target room temperature, t2 is the ambient temperature, t3 is the starting temperature of the curve, and t4 is the maximum temperature of the curve.

[0057] refer to Figure 4 According to the constraint formula for the target temperature of the water tank: T=t3+(t4-t3) / 35*(t1-t2), the constraint values ​​of the three independent variables are limited, and the corresponding target temperatures of the three water tanks are calculated by substituting the three ambient temperatures respectively.

[0058] Curve 1 is Figure 4 The curve is represented by the solid line. If the indoor set temperature in curve 1 is set to 20 degrees, the maximum temperature of the curve is set to 48 degrees, and the starting temperature of the curve is set to 20 degrees; then when the ambient temperature is 20 degrees, 0 degrees, and 15 degrees, the corresponding target water tank temperatures calculated according to the constraint formula are 20 degrees, 36 degrees, and 48 degrees, respectively.

[0059] refer to Figure 4 The curve 2 is obtained by translating curve 1. That is, curve 2 changes the target room temperature relative to curve 1. Curve 2 is represented by a dashed line.

[0060] refer to Figure 5 By changing the starting temperature and maximum temperature of curve 1, curve 3 is obtained, meaning that the slope of curve 3 has changed relative to curve 1.

[0062] An ambient temperature acquisition unit is used to acquire the ambient temperature.

[0063] The water tank target temperature acquisition unit is used to determine the water tank target temperature based on the ambient temperature and preset heating curve information; wherein, the preset heating curve information includes the indoor target room temperature, the curve start temperature and the curve maximum temperature, wherein the curve start temperature is less than the curve maximum temperature;
