[0002] In existing air conditioning designs, the air outlet grille generally exists as an indivisible whole. This design limitation makes it difficult to achieve fine-tuning of the air outlet direction during the air supply process. Specifically, due to the lack of flexibility of the air outlet grille, the airflow released by the air conditioner is often not effectively guided to every corner of the room, but tends to accumulate in a specific area, forming a so-called "hot spot" or "cold spot". This uneven distribution of airflow not only causes a significant imbalance in indoor temperature, but may also cause some areas to be overcooled or overheated, greatly reducing the user's comfort and overall experience. Therefore, a method that can effectively balance the indoor temperature is urgently needed. Summary of the invention

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

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figures 1-2 As shown, a method for indoor temperature balance adjustment based on air conditioning control includes the following steps:

[0054] Step S1: dividing the space where the air conditioner is located into an upper area and a lower area in a vertical direction;

[0055] Step S2: obtaining a startup mode of the air conditioner, and selecting an upper area or a lower area as a basic area according to the startup mode, and the other area as a regulating area;

[0056] Step S3: when the first frequency conversion signal appears, start to obtain the first temperature data of the basic area and the second temperature data of the middle part of the adjustment area respectively; determine whether the temperature difference between the first temperature data and the second temperature data is greater than the temperature threshold, if so, when the next frequency conversion signal appears, obtain the first temperature change amount of the basic area according to the first temperature data, and obtain the second temperature change amount of the adjustment area according to the second temperature data;

[0057] Step S4: when the variable frequency signal becomes an up-frequency signal, the fan in the space where the air conditioner is located is linked, and the direction of the fan is directed toward the base area, and the power of the fan is calculated according to the first temperature change amount and the second temperature change amount;

[0058] Step S5: Repeat step S4 until the temperature difference between the first temperature data and the second temperature data is less than the temperature threshold.

[0059] Due to the lack of flexibility of the air outlet grid, the airflow released by the air conditioner is often unable to be effectively guided to every corner of the room, but is easily accumulated in a specific area, forming a so-called "hot spot" or "cold spot". This non-uniform distribution of airflow not only causes a significant imbalance in the indoor temperature, but may also cause overcooling or overheating in some areas, greatly reducing the user's comfort and overall experience. For this reason, in the present invention, the air conditioner and the fan are linked, wherein the fan can be an independent networked intelligent fan, or a fan electrically connected to the air conditioner mainboard is set on the left and right sides of the air outlet grid. Since the gas temperature output by the air conditioner is different in different startup modes, when in the heating mode, the output is warm air, and in the cooling mode, the output is cold air. When heating, the heat runs upwards, and at this time, the warm air is easily accumulated above the space, and at this time, the warm air below the space is small, and it is easy to have a large temperature difference between the upper and lower layers of the space, affecting the user experience. Therefore, it is necessary to determine the basic area and the adjustment area according to the startup mode of the air conditioner. When the first frequency conversion signal appears, the air conditioner will be in a frequency reduction state. At this time, the temperature change in the space is close to the level without external influence. By obtaining the first temperature data of the basic area and the second temperature data of the middle of the adjustment area respectively, the normal natural temperature change between the two areas can be known.

[0060] Of course, before starting the fan for adjustment, it is necessary to determine whether the temperature difference between the first temperature data and the second temperature data is greater than the temperature threshold. Only when it is greater than the temperature threshold will it affect the user experience, and the fan needs to be adjusted at this time. If it is not greater than the temperature threshold, no subsequent adjustment is required. There will be data in the first temperature data and the second temperature data. When comparing the temperature difference, it is necessary to compare according to a unified standard. For example, when comparing the highest temperature, it is necessary to compare the highest temperature in the first temperature data with the highest temperature in the second temperature data. The highest temperature in the first temperature data cannot be compared with the lowest temperature in the second temperature data. There are many standards for comparison, and I will not list them too much here.

[0061] When the temperature difference between the two areas is greater than the temperature threshold, when the variable frequency signal becomes an up-frequency signal, the air conditioner will continue to output gas. At this time, the temperature difference between the two areas will gradually recover. At this time, it is necessary to start the fan to blow air to the basic area to increase the flow of air in the basic area, so that the gas in the basic area can flow into the adjustment area, so that the overall temperature of the space tends to be consistent.

[0062] The present invention allows users to enjoy a more uniform and comfortable indoor temperature environment through precise temperature zoning adjustment and a rapid response mechanism, so that the temperature in the space is kept appropriate and the discomfort caused by uneven temperature is avoided.

[0063] Preferably, the startup mode includes a cooling mode and a heating mode;

[0064] When the startup mode is cooling mode, the lower layer area is used as the basic area, and the upper layer area is used as the adjustment area;

[0065] When the startup mode is the heating mode, the upper layer area is used as the basic area, and the lower layer area is used as the adjustment area.

[0066] When in cooling mode, the output is cold air, which has a higher density and is easy to settle downwards. Therefore, in cooling mode, the lower area is used as the base area, and the fan blows air to the lower area, and the fan drives the cold air upwards, so that the temperature of the entire space is relatively balanced.

[0067] Preferably, the step of obtaining the first temperature change in step S3 is as follows:

[0068] Step S31: acquiring first temperature data of a base area at intervals of 30 seconds;

[0069] Step S32: using time as the horizontal coordinate and the first temperature data as the vertical coordinate, inputting the first temperature data into a cross coordinate system, fitting each coordinate in turn, and obtaining a current temperature change curve;

[0070] Step S33: obtaining the similarity between the current temperature change curve and the previous temperature change curve, and determining whether the similarity is greater than a similarity threshold; if the similarity is greater than the similarity threshold, calculating the first temperature change amount according to the maximum first temperature data, the minimum first temperature data and the current acquisition time, and changing the current temperature change curve to the previous temperature change curve;

[0071] If the similarity is less than the threshold, wait for the next frequency reduction signal to appear and re-execute steps S31 to S33; if the number of repeated executions is greater than the number threshold, stop executing step S31, obtain the maximum first temperature data, the minimum first temperature data of the last data collection, and the current collection time to calculate the first temperature change, and change the last current temperature change curve to the previous temperature change curve.

[0072] In the present invention, the temperature change is used to realize the final fan power control. However, in actual operation, since people may enter and exit the room, the air outside the room interacts with the air inside the room, resulting in a discrepancy between the temperature change and the actual natural change, which ultimately affects the power of the fan. For this reason, in the process of calculating the first temperature change in the present invention, the first temperature data collected will be used, and then the first temperature data will be used to construct the corresponding current temperature change curve. The similarity between the current temperature change curve and the previous temperature change curve is obtained, wherein the previous temperature change curve is the temperature change curve of the previous day. When it is used for the first time or used again for a long time, the previous temperature change curve is set to a straight line. When the similarity of the two curves is greater than the similarity threshold, it means that the temperature change is similar, there is no external interference, and the corresponding first temperature change can be calculated by the first temperature data obtained in the frequency conversion cycle. When the similarity of the two curves is less than the threshold, it means that the temperature change may fluctuate greatly, which is inconsistent with the previous one. The reason for this situation may be the reason of human entry and exit, or the reason of external weather changes, or the reason of adjusting the set temperature of the air conditioner. If the similarity of the curve is less than the similarity threshold due to human input, in the next frequency conversion cycle, if there is no human input, the current temperature change curve will still be similar to the previous temperature change curve. Therefore, when the similarity is less than the threshold, the next frequency reduction signal will be waited for to appear, and steps S31 to S33 will be re-executed; if the number of repeated executions is greater than the number threshold, it means that the temperature change is not caused by human input. At this time, the maximum first temperature data, the minimum first temperature data and the current acquisition time of the last data collection can be used to calculate the first temperature change amount, and the last current temperature change curve will be changed to the previous temperature change curve.

[0073] Similarly, the step of acquiring the second temperature variation is similar to the step of acquiring the first temperature variation, except that the source of the acquired data is different.

[0074] Preferably, if the first temperature data is missing in step S31, it is supplemented by the following formula:

[0075] P t (y) = b0*P t-2 (y)+b1*P t-1 (y)+b2*P t+1 (y)+b3*P t+2 (y);

[0076] in

[0077]

[0078] P t-2 (y) is the t-2th first temperature data, P t-1 (y) is the t-1th first temperature data, and u is a given curve parameter.

[0079] Since the data source of the first temperature change is determined by the similarity of the curve in the present invention, sometimes the device for obtaining the temperature may have data transmission problems, resulting in missing first temperature data. If the conventional mean value is directly used for filling, it may affect the curve fitting result. For this reason, in the present invention, the missing first temperature data is determined by the first temperature data of the two first temperature data before and after the missing data, so that the missing first temperature data can be based on the fitted curve, reducing the impact on the curve fitting.

[0080] Preferably, the formula for calculating the fan power according to the first temperature change and the second temperature change in step S4 is as follows:

[0081]

[0082] Where ΔT is the temperature difference between the base area and the adjustment area when the fan is turned on, T λ is the set air conditioning temperature, θ is the air flow influence coefficient, Δt is the time for the frequency conversion signal to change, Ts2 is the second temperature change, Ts1 is the first temperature change, λ is the temperature influence proportional parameter, and a is a constant to prevent the denominator from being 0.

[0090] When the startup mode is cooling mode, the lower layer area is used as the basic area, and the upper layer area is used as the adjustment area;
