Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0032] like Figure 1 As shown, in the first aspect, the embodiment of the present application provides an air conditioner control method, which includes S10 to S30. The type of the air conditioner 1 can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., which is not limited in the embodiment of the present application.

[0033] S10: Determine a standard speed of the indoor fan and a weight coefficient of the standard speed according to the current indoor temperature and the set temperature.

[0034] Here, the current indoor temperature can be determined by real-time measurement by a temperature sensor installed on the indoor side. The set temperature is the target temperature that the indoor environment is expected to reach. It can be an input temperature value manually input by the user through a remote control, a control panel, an intelligent terminal, etc., or it can be a comfortable temperature value automatically generated by the air conditioner 1 according to operating conditions such as the user's usage habits and current environmental information.

[0035] Here, a standard calculation model for determining the standard speed and weight coefficient of the indoor fan based on the current indoor temperature and the set temperature can be pre-set in the control system of the air conditioner 1. After obtaining the current indoor temperature and the set temperature, the current indoor temperature and the set temperature can be input into the standard calculation model to determine the standard speed of the indoor fan and the weight coefficient of the standard speed.

[0036] In some embodiments, when the air conditioner 1 is in cooling mode, if the current indoor temperature is higher than the set temperature and the current indoor temperature is significantly different from the set temperature, the standard speed of the indoor fan can be set to a larger speed value, and the weight coefficient corresponding to the standard speed is larger; if the current indoor temperature and the set temperature are relatively close or equal, the standard speed of the indoor fan can be set to a smaller speed value, and the weight coefficient corresponding to the standard speed is smaller; if the current indoor temperature is lower than the set temperature, the standard speed of the indoor fan can be set to a smaller speed value, and the weight coefficient corresponding to the standard speed is smaller.

[0037] In some embodiments, when the air conditioner 1 is in heating mode, if the current indoor temperature is lower than the set temperature and the current indoor temperature is significantly different from the set temperature, the standard speed of the indoor fan can be set to a larger speed value, and the weight coefficient corresponding to the standard speed is larger; if the current indoor temperature and the set temperature are relatively close or equal, the standard speed of the indoor fan can be set to a smaller speed value, and the weight coefficient corresponding to the standard speed is smaller; if the current indoor temperature is higher than the set temperature, the standard speed of the indoor fan can be set to a smaller speed value, and the weight coefficient corresponding to the standard speed is smaller.

[0038] S20: Determine a target speed of the indoor fan according to a standard speed of the indoor fan, a weight coefficient of the standard speed, indoor occupant information, and a comfortable speed variation model.

[0039] Here, the indoor personnel information can be determined by real-time measurement of a human body sensing device arranged on the indoor side, and the human body sensing device may include types such as ranging sensors and pyroelectric sensors. The type of information included in the indoor personnel information can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the indoor personnel information includes the number of indoor personnel, the distribution area where the indoor personnel are located, and the residence time of the indoor personnel in the distribution area; here, the indoor area in front of the air conditioner 1 can be pre-divided into multiple distribution areas, and the multiple distribution areas are arranged in sequence from the air conditioner 1 along the direction of the air conditioner 1, and the distances between any two distribution areas and the air conditioner 1 are not equal, so that the above-mentioned multiple distribution areas are arranged layer by layer from the inside to the outside around the air conditioner 1.

[0040] In some examples, the indoor area in front of the air conditioner 1 can be pre-divided into at least three distribution areas, and the at least three distribution areas can include a first distribution area, a second distribution area, and a third distribution area extending outward from the air conditioner 1, the first distribution area is arranged around the air conditioner 1 and is adjacent to the air conditioner 1, the second distribution area is arranged around the side of the first distribution area away from the air conditioner 1 and is connected to the first distribution area, and the third distribution area is arranged around the side of the second distribution area away from the air conditioner 1 and is connected to the second distribution area. In this way, the indoor personnel information may include the number of indoor personnel, the distribution areas where each indoor person is located, the stay time of the indoor person in each distribution area, etc. For example, the indoor personnel information may include that there are three people in the room, one of whom is located in the first distribution area and has stayed in the first distribution area for two minutes, no one is located in the second distribution area, and the other two are located in the third distribution area and have stayed in the third distribution area for five minutes, etc.

[0041] Here, the comfortable speed change model is a model of indoor fan speed change when the indoor personnel feel comfortable, which can be predetermined based on, for example, historical operation data and / or experimental test data of the air conditioner 1. The type of the comfortable speed change model can be determined according to actual needs, and can adopt speed change curves, prediction models determined based on data training, and other types, which are not limited in the embodiments of the present application. Exemplarily, the historical operation data and / or experimental test data of the air conditioner 1 at different speeds and various indoor personnel information can be used as sample data, and model training is performed based on learning algorithms such as linear regression algorithms, artificial neural network algorithms, or decision tree algorithms to obtain a comfortable speed change model in the form of, for example, a linear regression model, an artificial neural network model, or a decision tree model. Another exemplary method is to perform curve fitting on the historical operation data and / or experimental test data of the air conditioner 1 at different speeds and various indoor personnel information to obtain a comfortable speed change model in the form of a speed change curve.

[0042] Based on the standard speed of the indoor fan, the weight coefficient of the standard speed, the indoor occupant information and the comfortable speed change model, the speed value of the indoor fan that makes the current indoor occupants feel comfortable can be determined, which is the target speed of the indoor fan.

[0043] S30: Control the indoor fan to run at the above target speed.

[0044] After determining the target speed of the indoor fan, the indoor fan can be controlled to run at the target speed. When the indoor fan runs at the target speed, the air outlet of the air conditioner 1 can be blown to the current position of each indoor occupant at a more appropriate wind speed, so that the temperature of different areas is closer, and the comfort of indoor occupants at various positions is better taken into account.

[0045] Compared with the related art, the air conditioner control method provided in the embodiment of the present application can automatically adjust the speed of the indoor fan according to the current indoor temperature and the set temperature. When determining the target speed of the indoor fan, the indoor personnel information and the comfortable speed change model are considered together. Therefore, the determined target speed can make the indoor personnel located in various positions in the room feel comfortable. Therefore, when performing automatic wind speed adjustment, the needs of synchronous air supply in different areas can be better taken into account, eliminating or at least reducing to a large extent the temperature difference between different areas, and effectively improving the user's comfort.

[0046] like Figure 2 As shown, in some embodiments, S10 may include S11-S13.

[0047] S11: Determine the temperature difference between the current indoor temperature and the set temperature and the temperature difference range in which the temperature difference lies.

[0048] Here, a plurality of temperature difference intervals which are sequentially and continuously distributed may be pre-set in the control system of the air conditioner 1, and a corresponding internal fan speed value may be set for each temperature difference interval. In some examples, a plurality of temperature difference intervals may be set, such as a first temperature difference interval which is less than or equal to a first temperature difference threshold, a second temperature difference interval which is greater than the first temperature difference threshold and less than or equal to a second temperature difference threshold, a third temperature difference interval which is greater than the second temperature difference threshold and less than or equal to a third temperature difference threshold, and a fourth temperature difference interval which is greater than the third temperature difference threshold.

[0049] For example, when the air conditioner 1 is in cooling mode, the internal fan speed value corresponding to the first temperature difference interval, the internal fan speed value corresponding to the second temperature difference interval, the internal fan speed value corresponding to the third temperature difference interval, and the internal fan speed value corresponding to the fourth temperature difference interval gradually increase. The specific values ​​of the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold can be determined according to actual needs, and the embodiment of the present application does not limit this; for example, the first temperature difference threshold can be 0°C.

[0050] As another example, when the air conditioner 1 is in the heating mode, the internal fan speed value corresponding to the first temperature difference interval, the internal fan speed value corresponding to the second temperature difference interval, the internal fan speed value corresponding to the third temperature difference interval, and the internal fan speed value corresponding to the fourth temperature difference interval gradually decrease. The specific values ​​of the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold can be determined according to actual needs, and the embodiment of the present application does not limit this; as an example, the third temperature difference threshold can be 0°C.

[0051] S12: Determine a standard speed of the indoor fan according to the temperature difference range in which the temperature difference falls.

[0052] After determining the temperature difference interval in which the temperature difference between the current indoor temperature and the set temperature lies, the indoor fan speed value corresponding to the temperature difference interval can be determined, and the indoor fan speed value is used as the standard speed of the indoor fan.

[0053] S13: Determine a weight coefficient of the standard speed according to the temperature difference between the current indoor temperature and the set temperature.

[0054] Here, a weight calculation model for determining a weight coefficient of the standard speed based on the temperature difference between the current indoor temperature and the set temperature can be pre-set in the control system of the air conditioner 1. After determining the temperature difference between the current indoor temperature and the set temperature, the temperature difference can be input into the weight calculation model to determine the weight coefficient of the standard speed.

[0055] The specific steps for determining the target speed of the indoor fan can be determined according to actual needs, and the present application embodiment does not limit this. Figure 3 As shown, in some embodiments, S20 may include S21-S22.

[0056] S21: Determine a corrected speed of the indoor fan according to a standard speed of the indoor fan, a weight coefficient of the standard speed, and indoor personnel information.

[0057] Here, a speed correction model can be pre-set in the control system of the air conditioner 1. The speed correction model takes the standard speed of the indoor fan, the weight coefficient of the standard speed and the indoor personnel information as input values, and takes the corrected speed of the indoor fan as output value. In this way, after determining the standard speed of the indoor fan, the weight coefficient of the standard speed and the indoor personnel information, the standard speed of the indoor fan, the weight coefficient of the standard speed and the indoor personnel information can be input into the speed correction model to determine the corrected speed of the indoor fan.

[0058] S22: According to the modified speed of the indoor fan and the comfortable speed variation model, a target speed of the indoor fan is determined by fitting.

[0059] After determining the modified speed and comfortable speed change model of the indoor fan, the modified speed and comfortable speed change model of the indoor fan can be fitted to obtain a smooth speed change curve; the speed change curve takes the time axis as the horizontal axis, and the target speed of the indoor fan can be determined based on the speed change curve. The target speed is determined based on the current indoor temperature and the set temperature, the indoor personnel information and the comfortable speed change model, so that the speed of the indoor fan can be automatically adjusted with the change of the current indoor temperature, and can take into account the need for synchronous air supply in different areas, eliminate or at least reduce the temperature difference between different areas to a large extent, and effectively improve the user's comfort.

[0060] The steps for determining the corrected rotation speed can be determined according to actual needs, and the present application embodiment does not limit this. Figure 4 As shown, in some examples, S21 may include S211 to S212.

[0061] S211: Determine the indoor personnel distribution coefficient according to the indoor personnel information.

[0062] Here, a personnel distribution coefficient calculation model can be pre-set in the control system of the air conditioner 1. The personnel distribution coefficient model can take indoor personnel information such as the number of indoor personnel, the distribution area where the indoor personnel are located, and the residence time of the indoor personnel in the distribution area as input, and take the indoor personnel distribution coefficient as output. The indoor personnel distribution coefficient can be a single value reflecting the overall distribution of all indoor personnel, so that the personnel distribution coefficient calculation model can output a discrete value based on an input; or, the indoor personnel distribution coefficient can also be a series of values ​​reflecting the distribution of each indoor person, so that the personnel distribution coefficient calculation model can output an array containing multiple values ​​based on an input, and each value in the array can respectively represent the residence position and residence time weight of each indoor person.

[0063] S212: Determine a corrected speed of the indoor fan according to a standard speed of the indoor fan, a weight coefficient of the standard speed, and an indoor occupant distribution coefficient.

[0064] Here, the speed correction model can use the standard speed of the indoor fan, the weight coefficient of the standard speed and the indoor personnel distribution coefficient as input values, and use the corrected speed of the indoor fan as output value. In this way, the standard speed of the indoor fan, the weight coefficient of the standard speed and the indoor personnel distribution coefficient are input into the speed correction model to determine the corrected speed of the indoor fan.

[0065] By setting S211~S212, the corrected speed of the indoor fan can be determined more accurately, so that the determined corrected speed can better match the distribution of indoor personnel, and then the target speed determined based on the corrected speed can better take into account the distribution of indoor personnel, so that when automatic wind speed adjustment is performed, the need for synchronous air supply in different areas can be better taken into account, eliminating or at least reducing to a large extent the temperature difference between different areas, and effectively improving the user comfort.

[0066] like Figure 5 As shown, in some examples, before S22, the air conditioner control method may include S201 to S202.

[0067] S201: Determine the indoor personnel distribution type according to the indoor personnel information.

[0068] Here, the indoor personnel distribution types can be classified according to different distribution conditions, and multiple indoor personnel distribution types can be determined, and an indoor personnel distribution type library can be established according to the multiple predetermined indoor personnel distribution types. Fig. 9As shown, exemplarily, the indoor area in front of the air conditioner 1 can be pre-divided into the above-mentioned at least three distribution areas. The indoor personnel distribution type library may include multiple indoor personnel distribution types, and the multiple indoor personnel distribution types may include, for example, the following distribution types: only one of the first distribution area, the second distribution area and the third distribution area has people, and the other distribution areas have no people; the first distribution area has no people, and the second distribution area and the third distribution area both have people; the first distribution area and the second distribution area both have people, and the third distribution area has no people; the first distribution area and the third distribution area both have people, and the second distribution area has no people; the first distribution area, the second distribution area and the third distribution area all have people; and so on, which are not listed one by one here; further, for the above-listed distribution types, they can also be further subdivided into multiple types according to the number of people and the stay time in each distribution area, so as to form a larger number and more detailed distribution types.

[0069] In this way, after the indoor personnel information is acquired, the indoor personnel distribution type corresponding to the indoor personnel information can be determined in the indoor personnel distribution type library.

[0070] S202: Determine a comfortable speed change model corresponding to the indoor occupant distribution type according to the indoor occupant distribution type.

[0071] Here, the comfortable speed change model corresponding to each indoor occupant distribution type in the indoor occupant distribution type library can be pre-determined based on, for example, historical operation data and / or experimental test data of the air conditioner 1, and then multiple comfortable speed change models corresponding to the above multiple indoor occupant distribution types can be obtained, and multiple comfortable speed change model libraries can be established based on the above multiple comfortable speed change models. In this way, after determining the indoor occupant distribution type, the comfortable speed change model corresponding to the indoor occupant distribution type can be determined in the comfortable speed change model library.

[0072] By setting S201~S202, the comfortable speed change model that matches the current indoor occupant distribution can be determined more accurately, and then the target speed that matches the current indoor occupant distribution can be determined according to the comfortable speed change model. Therefore, when performing automatic wind speed adjustment, the needs of synchronous air supply in different areas can be better taken into account, eliminating or at least reducing to a large extent the temperature difference between different areas, and effectively improving the user comfort.

[0073] like Figure 6 As shown, in some other embodiments, S20 may include S21'-S24'.

[0074] S21': Determine the indoor personnel distribution type according to the indoor personnel information.

[0075] Here, the specific method of S21' can refer to the introduction of S201 above, which will not be repeated here.

[0076] S22': According to the indoor occupant distribution type, a comfortable speed change model corresponding to the indoor occupant distribution type is determined in a comfortable speed change model library.

[0077] Here, the specific method of S22' can refer to the introduction of S202 above, which will not be repeated here.

[0078] S23': According to the current speed change curve of the indoor fan and the comfortable speed change model, a target speed change curve is determined by fitting.

[0079] Here, the current speed change curve of the indoor fan refers to the speed change curve where the current speed of the indoor fan is located; illustratively, for two adjacent moments t0 and t1, the current speed change curve of the indoor fan at moment t1 may be the target speed change curve determined by S23' at moment t0, and the target speed of the indoor fan at moment t1 may be determined based on the target speed change curve determined by S23' at moment t0 and through the following S24', and the target speed of the indoor fan at moment t1 is the current speed of the indoor fan at moment t1.

[0080] By fitting the current speed change curve of the indoor fan and the comfortable speed change model, a smooth speed change curve, i.e., a target speed change curve, can be determined. The target speed change curve takes the time axis as the horizontal axis, and the target speed of the indoor fan can be determined based on the speed change curve. Taking three consecutive moments t0, t1, and t2 as examples, the comfortable speed change model determined at time t1 is fitted and corrected according to the current speed change curve of the indoor fan at time t1 (i.e., the target speed change curve determined by S23' at time t0), and a smooth speed change curve, i.e., the target speed change curve of the indoor fan at time t2 can be determined. Along the target speed change curve, the indoor fan can smoothly transition from the current speed at time t1 to the target speed at time t2, thereby reducing the interference effect of wind speed regulation on indoor users and achieving a better regulation effect of no wind feeling or no obvious wind feeling change.

[0081] S24': Determine the target speed of the indoor fan according to the standard speed of the indoor fan, the weight coefficient of the standard speed and the target speed variation curve.

[0082] After determining the standard speed of the indoor fan, the weight coefficient of the standard speed and the target speed change curve, the target speed of the indoor fan can be determined. The speed of the indoor fan is adjusted according to the target speed, so that the speed of the indoor fan changes smoothly from the current speed to the target speed, reducing the interference of wind speed adjustment on indoor users, and achieving a better adjustment effect of no wind feeling or no obvious wind feeling change.

[0083] like Figure 7 As shown, in some embodiments, before S20, the air conditioner control method may include S101-S102.

[0084] S101: Divide the indoor area in front of the air conditioner 1 into a plurality of distribution areas.

For the division method of multiple distribution areas, please refer to the above corresponding introduction, which will not be repeated here.

[0086] S102: Acquire indoor personnel information, which includes the number of indoor personnel, the distribution area where the indoor personnel are located, and the stay time of the indoor personnel in the distribution area.

[0088] like Figure 8 As shown, in a third aspect, an embodiment of the present application provides an air conditioner 1, the air conditioner 1 includes a processor 10 and a memory 20, the memory 20 stores a computer program, and the computer program is executed by the processor 10 to implement the air conditioner control method provided in any of the above embodiments. The type of the air conditioner 1 can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., which is not limited in the embodiment of the present application.
