[0030] Figure 1 It is a schematic flow chart of an air volume regulating method according to an exemplary embodiment. This specification provides method operation steps such as in the embodiment or flow chart, but based on routine or non-creative labor, it may include more or fewer operation steps. The step sequence listed in the embodiment is only one way among the execution sequences of numerous steps, and does not represent the only execution sequence. When the actual system or server product executes, it can be executed in the order shown in the embodiment or the drawing or in parallel (for example, in an environment of parallel processors or multi-threaded processing). Specifically, as Figure 1 shown, taking the live broadcast controller as the execution subject, an embodiment of an air volume regulating method of the present application is introduced. The above method may include:

[0031] S101: Obtain a first external wind pressure and a first target air volume corresponding to the first thermal charge of the current fan.

[0032] In a specific embodiment, the first external wind pressure can be the external wind pressure corresponding to the current fan when starting the current fan using the second preset phase current; the first hot load can be the hot load corresponding to the current fan when starting the current fan using the second preset phase current; the current fan can be the fan in the water heater in use; the first target air volume can be the optimal air volume used by the current fan when the current fan is in the first heat load condition.

[0033] When encountering extreme weather during the use of the current water heater, the first target air volume and the first external voltage corresponding to the first hot charge of the current fan in the current water heater are obtained, and then the air volume of the current fan is adjusted.

[0034] Figure 2 It is a schematic flow chart of obtaining the first external wind pressure provided according to an exemplary embodiment. In an alternative embodiment, as Figure 2 shown, the above-mentioned obtaining of the first external wind pressure may include:

[0035] S201: Obtain the target rotation speed duration and the wind pressure coefficient of the current fan;

[0036] S203: Determine the first external wind pressure based on the target rotation speed duration and the wind pressure coefficient.

[0037] In a specific embodiment, the target rotation speed duration is the duration experienced by the current fan when rotating from the current rotation speed to the target rotation speed when starting the current fan based on the second preset phase current; the second preset phase current is the maximum phase current for the operation of the current fan; the target rotation speed can be the rotation speed that the current fan should reach when controlling the operation of the current fan using the second preset phase current.

[0038] Specifically, after obtaining the target rotation speed duration and the wind pressure coefficient of the current fan, further, based on the formula F = kt (1), where F represents the first external wind pressure, t represents the target rotation speed duration, and k represents the wind pressure coefficient, the calculation of the first external wind pressure is performed; optionally, the current fan has a function of detecting changes in wind pressure. When the current fan detects a change in the external wind pressure, the second preset phase current is used to control the operation of the current fan. Correspondingly, the duration experienced from the current rotation speed when starting to control the operation of the current fan using the second preset phase current to reaching the target rotation speed, that is, the target rotation speed duration, is obtained. Correspondingly, the obtained target rotation speed duration and the stored wind pressure coefficient are substituted into formula (1) to obtain the first external wind pressure.

[0039] In the above embodiment, the first external voltage is calculated and determined through the target rotation speed duration of the current fan and the wind pressure coefficient stored in the system, improving the accuracy and real-time performance of determining the first external voltage.

[0040] S103: Calculate and determine the first target matching phase current based on the first external wind pressure and the first target air volume; and control the current fan to operate based on the first target matching phase current to obtain the first rotational speed of the current fan.

[0041] In a specific embodiment, the first target matching phase current may be the matching phase current corresponding to the current fan under the first external wind pressure; the first rotational speed may be the rotational speed of the current fan when the current fan is controlled to operate by the first target matching phase current;

[0042] Specifically, when calculating and determining the first external voltage, calculate and determine the first target matching phase current based on the first external voltage and the calculated first target air volume. Specifically, based on the formula I = s 0 F + s 1 Q 1 (2), where F represents the first external voltage, Q 1 represents the first target air volume, I represents the first target matching phase current, s 0 represents the wind pressure coefficient, s 1 represents the air volume coefficient. Optionally, substitute the previously calculated first external wind pressure and the first target air volume into formula (2) to determine the first target matching phase current. Further, control the operation of the current fan based on the first target matching phase current and obtain the first rotational speed of the current fan when it operates under the control of the first target matching phase current.

[0043] S105: Detect the change in the first external wind pressure, and when the first external wind pressure changes, determine the current air volume based on the first rotational speed and the first target matching phase current.

[0044] In a specific embodiment, the current air volume may be the air volume of the current fan when the first external wind pressure changes. Specifically, the current fan continuously detects the change in the first external wind pressure, and when the first external wind pressure changes, calculate and determine the current air volume based on the previously calculated first rotational speed and the first target matching phase current.

[0045] Figure 3 is a flowchart showing a process for determining the current air volume based on the first rotational speed and the first target matching phase current according to an exemplary embodiment. In an optional embodiment, as Figure 3 shown, the above process for determining the current air volume based on the first rotational speed and the first target matching phase current may include:

[0046] S301: Obtain the rotational speed coefficient and the matching coefficient;

[0047] S303: Perform operations based on the first rotational speed and the rotational speed coefficient to determine the rotational speed change information;

[0048] S305: Determine the matching change information based on the matching coefficient, the first rotational speed, and the first target matching phase current;

[0049] S307: Determine the current air volume based on the rotational speed change information and the matching change information.

[0050] In a specific embodiment, in the case of a change in the first external voltage, the stored rotational speed coefficient and matching coefficient in the current fan are called, and a multiplication operation is performed based on the first rotational speed and the rotational speed coefficient to calculate and determine the rotational speed change information. Further, the matching change information is calculated and determined based on the matching coefficient, the first rotational speed, and the first target matching phase current. Correspondingly, based on the calculated rotational speed change information and the matching change information, the current air volume is calculated and determined. Correspondingly, based on the formula Q 2 = a 0 In 3 + a 1 n 3 (3), where Q 2 represents the current air volume, a 0 represents the matching coefficient, a 1 represents the rotational speed coefficient, I represents the first matching phase current, and n represents the first rotational speed. Correspondingly, the rotational speed coefficient, the matching coefficient, the first rotational speed, and the first target matching phase current are substituted into formula (3) to calculate the corresponding change information, and then the current air volume is calculated and determined.

[0051] In the above embodiment, the rotational speed change information is calculated and determined by multiplying the rotational speed coefficient and the first rotational speed, and the matching change information is calculated and determined by the matching coefficient, the first rotational speed, and the first target matching phase current. Then, based on the calculated rotational speed change information and the matching change information, the current air volume is calculated and determined, which improves the rigor and real-time performance of determining the current air volume, and further improves the convenience of air volume adjustment.

[0052] S107: Determine the air volume comparison result based on the current air volume and the first target air volume; and based on the air volume comparison result, adjust the phase current of the current fan to the first target matching phase current so that the current air volume of the current fan is adjusted to the first target air volume.

[0053] In a specific embodiment, the air volume comparison result is used to indicate whether the current air volume is greater than the first target air volume; specifically, when the current air volume and the first target air volume are obtained, the current air volume and the first target air volume are compared. Correspondingly, the air volume comparison result is determined. Further, based on the determined air volume comparison result, the phase current of the current fan is adjusted, that is, the current phase current of the current fan is adjusted to the first target matching phase current. Then, by adjusting the phase current of the current fan to the first target matching phase current, the current air volume of the current fan is adjusted to the first target air volume, so as to realize the adjustment of the air volume of the current fan by adjusting the phase current.

[0054] In an alternative embodiment, based on the air volume comparison result, adjusting the second preset phase current of the current fan to the first target matching phase current to adjust the current air volume of the current fan to the first target air volume may include:

[0055] When the air volume comparison result indicates that the current air volume is greater than the first target air volume, the current fan is controlled to operate by the first preset phase current, and the first preset phase current of the current fan is adjusted to the first target matching phase current, so that the current air volume of the current fan is adjusted to the first target air volume.

[0056] In a specific embodiment, the first preset phase current is the minimum phase current for the operation of the current fan; specifically, when the air volume comparison result indicates that the current air volume is greater than the first target air volume, the current fan is controlled to operate by the first preset phase current, and the first preset phase current is adjusted to the first target matching phase current, thereby adjusting the current air volume of the current fan to the first target air volume.

[0057] In an alternative embodiment, based on the air volume comparison result, adjusting the second preset phase current of the current fan to the first target matching phase current to adjust the current air volume of the current fan to the first target air volume may further include:

[0058] When the air volume comparison result indicates that the current air volume is less than the first target air volume, the current fan is controlled to operate by the second preset phase current, and the first preset phase current of the current fan is adjusted to the first target matching phase current, so that the current air volume of the current fan is adjusted to the first target air volume.

[0059] In a specific embodiment, when the air volume comparison result indicates that the current air volume is less than the first target air volume, the operation of the current fan is controlled using the second preset phase current. Further, the phase current of the current fan is adjusted, that is, the second preset phase current of the current fan is adjusted to the first target matching phase current. Optionally, the first target matching phase current is less than the second preset phase current and greater than the first preset phase current; correspondingly, the air volume of the current fan is adjusted, that is, adjusted from the current air volume to the first target air volume.

[0060] In the above embodiments, by listing different indications of the air volume comparison result and then performing different adjustments, the convenience and accuracy of air volume adjustment are achieved. By realizing the air volume adjustment of the current fan, the normal use of the current water heater is ensured, and thus the performance of the current water heater is improved.

[0061] Figure 4 is a schematic flowchart of a process for determining whether to perform air volume adjustment according to a change in the second external wind pressure. In an alternative embodiment, as Figure 4As shown, the above method may further include:

[0062] S401: Re-obtain the second rotational speed of the current fan after the change in the first external wind pressure;

[0063] S403: Determine the second external wind pressure based on the second rotational speed and the first target matching phase current; and detect the change in the second external wind pressure, and re-adjust the air volume in the case of a change in the second external wind pressure.

[0064] In a specific embodiment, the second rotational speed may be the rotational speed corresponding to the changed wind pressure of the current fan in the case of a change in the first external wind pressure; specifically, when the current fan detects that the external wind pressure is no longer the first external wind pressure, that is, in the case of a change in the first external wind pressure, the second rotational speed of the current fan is obtained. Further, the second external wind pressure is calculated and determined based on the obtained second rotational speed and the first target matching phase current, and the change in the second external wind pressure is detected at any time, and in the case of a change in the second external wind pressure, the air volume is re-adjusted.

[0065] In the above embodiment, the second external wind pressure is determined by the second rotational speed and the first target matching phase current, and it is detected whether the second external wind pressure changes. In the case of a change in the second external wind pressure, the air volume of the current fan is re-adjusted, improving the rigor, variability, and real-time performance of the air volume adjustment.

[0066] Figure 5 It is a schematic flowchart of a process for adjusting the air volume of the current fan from the second air volume to the second target air volume in the case of a change in the second external wind pressure according to an exemplary embodiment.

[0070] In a specific embodiment, the second thermal charge may be the thermal charge corresponding to the current fan under the condition of the change of the second external wind pressure; the second target air volume may be the air volume that the current fan should reach based on the second thermal charge; the second target matching phase current may be the matching phase current corresponding to the current fan under the second external wind pressure; the second air volume may be the air volume of the current fan under the condition of the change of the second external wind pressure; the air volume matching phase current may be the matching phase current corresponding to the current fan operating based on the second air volume under the condition of the second external wind pressure;

[0071] Specifically, under the condition of the change of the second external wind pressure, the second target air volume corresponding to the second thermal charge of the current fan is obtained. Further, the second target matching phase current is calculated and determined based on the second target air volume and the second external wind pressure. Optionally, the second target matching phase current is calculated and determined according to formula (2). Correspondingly, the second target air volume and the second external voltage are substituted into formula (2), and the second target matching phase current can be calculated. Further, based on the second rotational speed and the second target matching phase current, the second air volume is calculated and determined. Correspondingly, based on the second air volume and the second external wind pressure, the matching phase current is calculated and determined to obtain the air volume matching phase current. Further, the phase current is adjusted. Correspondingly, the phase current of the current fan is adjusted from the air volume matching phase current to the second target matching phase current, thereby realizing the adjustment of the air volume of the current fan from the second air volume to the second target air volume.

[0072] In the above embodiment, the second air volume is calculated and determined through multiple coefficients, the second rotational speed, and the second target matching phase current, which improves the accuracy of determining the second air volume, and further improves the accuracy of adjusting the air volume.

[0078] S609: Determine the second external wind pressure based on the second rotational speed change information, matching change information, and wind pressure change information.

[0079] In a specific embodiment, when a change in the first external wind pressure is detected, the wind pressure coefficient, rotational speed coefficient, and matching coefficient stored in the system are used. Further, based on the second rotational speed and the rotational speed coefficient, the second rotational speed change information is calculated and determined. Based on the matching coefficient, the second rotational speed, and the first target matching phase current, the matching change information is calculated and determined. Based on the wind pressure coefficient and the first target matching phase current, the wind pressure change information is calculated and determined. Further, the second rotational speed change information, the second matching change information, and the wind pressure change information are subjected to addition and subtraction calculations to obtain the second external wind pressure. Correspondingly, based on the formula where F 2 represents the second external wind pressure, and the aforementioned wind pressure coefficient, rotational speed coefficient, matching coefficient, second rotational speed, and first target matching phase current are substituted into formula (4) for calculation to calculate and determine the second external wind pressure.

[0080] In the above embodiment, the second external voltage is calculated and determined through different coefficients, the second rotational speed, and the first target matching phase current, making the determination of the second external voltage have a certain degree of accuracy. Furthermore, by detecting the change in the second external voltage, it can be determined whether to adjust the air volume of the current fan, improving the accuracy of air volume adjustment.
