[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In the description of the embodiments of the present invention, it should be noted that the terms “first”, “second”, etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0050] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0051] Combine the following Figure 1-Figure 6 The present invention describes an air conditioner control method, an air conditioner control device and an air conditioner.

[0052] According to an embodiment of the first aspect of the present invention, referring to Figure 1 As shown, the present invention provides a control method for an air conditioner, which mainly includes the following steps:

[0053] S100: When the air conditioner is in cooling operation, obtain a trend of indoor ambient temperature change within a preset judgment period.

[0054] Specifically, within the preset judgment period, the indoor ambient temperature is detected once every first preset time period, and the detection is performed multiple times in succession;

[0055] According to the multiple indoor ambient temperatures detected, the indoor ambient temperature change trend is obtained, namely:

[0056] ΔT=[(T y -T1)+(T y-1 -T2)+……+(T y / 2+1 -T y / 2 )] / y / 2;

[0057] Among them, ΔT is the trend of indoor ambient temperature change; T1, T2...T yThey are the indoor ambient temperatures detected y times respectively, and y is an even number.

[0058] For example, when the indoor unit of the air conditioner is running in cooling mode, it starts to detect and store the indoor ambient temperature 2 minutes after the indoor fan starts running. It detects once every 1 minute, and four consecutive detections serve as a judgment cycle, that is, each preset judgment cycle is 4 minutes, and the four detection values ​​are T1, T2, T3, and T4 respectively. Then, the indoor ambient temperature change trend of each preset judgment cycle is: ΔT = [(T4-T1)+(T3-T2)] / 2.

[0059] S200, determining that the difference between the last indoor ambient temperature in the indoor ambient temperature variation trend and the set temperature is less than or equal to the target set value, and controlling the indoor fan of the air conditioner to run at a target preset speed according to the indoor ambient temperature variation trend.

[0060] Among them, the last indoor ambient temperature T in the indoor ambient temperature change trend in the previous preset judgment cycle y As the first indoor ambient temperature T1 in the indoor ambient temperature change trend within the next preset judgment cycle, the continuity of control can be achieved according to the continuity of temperature change, effectively improving the control accuracy, and the approximate change trend of the indoor ambient temperature in the next preset judgment cycle can be judged according to the indoor ambient temperature change trend of the current preset judgment cycle, thereby achieving the effect of advance control and effectively improving the control efficiency, so that the indoor ambient temperature can be quickly maintained stable, fluctuations can be reduced, and user experience can be improved.

[0061] It is understandable that when the air conditioner is running in cooling mode, there are multiple preset judgment cycles, and temperature judgment and control are performed every preset judgment cycle. For example, the preset judgment cycle is 4 minutes, that is, the temperature is judged every 4 minutes.

[0062] Moreover, as the air conditioner indoor unit operates for cooling, the indoor ambient temperature gradually decreases. When the indoor ambient temperature drops to the point where the difference between the indoor ambient temperature and the set temperature is less than or equal to the target set value, that is, the indoor ambient temperature is close to the set temperature, the indoor fan of the air conditioner is controlled to run at an appropriate speed according to the trend of the indoor ambient temperature change. This can maintain the indoor ambient temperature stable and reduce fluctuations, thereby extending the operating time of the indoor unit and avoiding frequent start and stop of the indoor unit.

[0063] Therefore, the control method of the air conditioner provided in the embodiment of the present invention can intelligently and automatically adjust the fan speed of the air-conditioning indoor unit according to the indoor ambient temperature change trend and the difference between the indoor ambient temperature and the user-set temperature, so as to balance the cooling required indoors and the cooling provided by the air-conditioning indoor unit. If the indoor ambient temperature changes, the indoor fan speed will change dynamically to maintain the indoor ambient temperature and reduce the fluctuation of the indoor ambient temperature, thereby achieving the purpose of extending the operating time of the air-conditioning indoor unit and reducing the number of starts and stops of the air-conditioning indoor unit, effectively improving the user's comfort experience.

[0064] According to one embodiment of the present invention, referring to Figure 2 As shown, the step of determining that the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is less than or equal to the target set value, and controlling the indoor fan of the air conditioner to run to the target preset speed according to the indoor ambient temperature change trend specifically includes:

[0065] S201, determining that the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than or equal to the first set value and less than or equal to the target set value:

[0066] S2011, if the indoor ambient temperature change trend is greater than the first preset value, control the indoor fan to increase the speed;

[0067] S2012: If the indoor ambient temperature change trend is greater than or equal to the second preset value and less than or equal to the first preset value, control the indoor fan to continue running at the current speed;

[0068] S2013: If the indoor ambient temperature change trend is less than the second preset value, control the indoor fan to reduce the speed.

[0069] The step of controlling the indoor fan to increase or decrease its speed specifically includes: controlling the speed of the indoor fan to increase or decrease its speed by one gear.

[0070] Specifically, as the air conditioner operates in refrigeration mode, the indoor ambient temperature gradually decreases. When the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than or equal to the first set value and less than or equal to the target set value, that is, when the indoor ambient temperature drops to a level closer to the set temperature, if the indoor ambient temperature change trend is greater than the first preset value, it indicates that the indoor ambient temperature has a tendency to rise. At this time, the speed of the indoor fan is increased, for example, the wind speed is increased by one level to lower the temperature and keep the indoor ambient temperature stable. If the indoor ambient temperature change trend is greater than or equal to the second preset value and less than or equal to the first preset value, it indicates that the indoor ambient temperature fluctuates less and tends to be in a more stable state. At this time, the indoor fan can maintain the current speed. If the indoor ambient temperature change trend is less than the second preset value, it indicates that the indoor ambient temperature has a tendency to fall. At this time, the speed of the indoor fan is reduced, for example, the wind speed is reduced by one level to increase the temperature and keep the indoor ambient temperature stable.

[0071] According to one embodiment of the present invention, referring to Figure 3 As shown, the step of determining that the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is less than or equal to the target set value, and controlling the indoor fan of the air conditioner to run to the target preset speed according to the indoor ambient temperature change trend, also includes:

[0072] S202: Determine whether the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than or equal to zero and less than a first set value:

[0073] S2021. If the indoor ambient temperature change trend is greater than the first preset value, the indoor fan is controlled to continue to run at the current speed;

[0074] S2022: If the indoor ambient temperature change trend is greater than or equal to the second preset value and less than or equal to the first preset value, control the indoor fan to reduce the speed;

[0075] S2023: If the indoor ambient temperature change trend is less than the second preset value, control the indoor fan to reduce the speed.

[0076] The step of controlling the indoor fan to reduce its speed specifically includes: controlling the speed of the indoor fan to reduce its operating gear by one gear.

[0077] Specifically, when the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than or equal to zero and less than the first set value, that is, when the indoor ambient temperature drops to be closer to the set temperature, if the indoor ambient temperature change trend is greater than the first preset value, it indicates that the indoor ambient temperature fluctuation is small and tends to be relatively stable. At this time, the indoor fan can maintain the current speed; if the indoor ambient temperature change trend is greater than or equal to the second preset value and less than or equal to the first preset value, it indicates that the indoor ambient temperature has a downward trend. At this time, reduce the speed of the indoor fan, for example, reduce the wind speed by one level, to increase the temperature, and keep the indoor ambient temperature stable; if the indoor ambient temperature change trend is less than the second preset value, it indicates that the indoor ambient temperature has a further downward trend. At this time, reduce the speed of the indoor fan, for example, reduce the wind speed by one level, to increase the temperature, and keep the indoor ambient temperature stable.

[0078] According to one embodiment of the present invention, referring to Figure 4 As shown, the step of determining that the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is less than or equal to the target set value, and controlling the indoor fan of the air conditioner to run to the target preset speed according to the indoor ambient temperature change trend, also includes:

[0079] S203, determining that the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than or equal to a second set value and less than zero, and controlling the indoor fan to run at the lowest speed.

[0080] When the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than or equal to the second set value and less than zero, it indicates that the indoor ambient temperature has dropped to a level close to the set temperature. At this time, there is no need to consider the indoor ambient temperature change trend. The indoor fan can be operated at the lowest speed to achieve a balance between the cooling capacity provided by the air-conditioning indoor unit and the cooling capacity required by the user environment, thereby reducing temperature fluctuations.

[0081] Therefore, the embodiment of the present invention controls the speed of the indoor fan to a suitable target value according to the changing trend of the indoor ambient temperature and the temperature difference between the indoor ambient temperature and the set temperature, so as to achieve a balance between the cooling capacity provided by the air-conditioning indoor unit and the cooling capacity required by the user environment, thereby achieving the purpose of stabilizing the indoor ambient temperature and reducing temperature fluctuations, thereby improving the user experience.

[0082] According to one embodiment of the present invention, referring to Figure 1 As shown, the control method of the air conditioner of the present invention also includes:

[0083] S300: Determine that the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than the target set value, and control the indoor fan to run at the speed set by the user.

[0084] Specifically, when the air conditioner starts to operate in cooling mode, if the difference between the last indoor ambient temperature in the indoor ambient temperature change trend and the set temperature is greater than the target set value, it indicates that the temperature difference between the two is large. At this time, the indoor fan speed is controlled to run according to the speed set by the user, which can achieve the purpose of rapid cooling.

[0085] The control method of the air conditioner provided by the present invention is described below with reference to a specific example, which generally includes:

[0086] When the air conditioner starts running in cooling mode, if T 环温 -T 设定 >2℃, in order to achieve the purpose of rapid cooling, the indoor fan speed runs according to the user's set speed. As the air conditioner indoor mechanism cools, the indoor ambient temperature T 环温 Gradually decrease, when the indoor ambient temperature T 环温 Reduce to meet T 环温 -T 设定 ≤2℃, in order to extend the operation time of the indoor unit and avoid frequent start and stop of the indoor unit, the indoor fan speed shall be implemented according to the following table. 环温 The last indoor ambient temperature of the indoor ambient temperature change trend ΔT in the preset judgment period, that is, the first indoor ambient temperature of the indoor ambient temperature change trend ΔT in the next preset judgment period. 环温 and set temperature T 设定The indoor fan speed is adjusted to an appropriate value based on the temperature difference and the changing trend of the indoor ambient temperature to achieve a balance between the cooling capacity provided by the air-conditioning indoor unit and the cooling capacity required by the user environment.

[0087]

[0088] The embodiment of the present invention performs rapid cooling in the early stage of refrigeration. As the refrigeration is running, when the indoor ambient temperature drops to close to the set temperature, the balance between the required indoor cooling capacity and the cooling capacity provided by the air-conditioning indoor unit is achieved by adjusting the indoor fan speed. If the indoor ambient temperature changes, the indoor fan speed changes dynamically, which can maintain the indoor ambient temperature stable and reduce temperature fluctuations, thereby achieving the purpose of extending the operating time of the air-conditioning indoor unit and reducing the number of starts and stops of the air-conditioning indoor unit, thereby improving the user experience.
