[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application are further elaborated in detail below in conjunction with the drawings and embodiments. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0025] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0026] The terms "first / second / third" involved in the present application are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The embodiment of the present application provides a method for controlling an air conditioner, referring to Figure 1 As shown, the method comprises the following steps:

[0030] Step 101: Obtain a first time when the no wind function is turned on and a second time when the fresh air function is turned on.

[0031] It is understandable that the windless function is a function of the air conditioner. In this function mode, the air conditioner changes the air supply volume through the indoor fan so that the air flow speed and wind feeling index in the target area can meet the comfort requirements. The fresh air function is a fresh air ventilation function of the air conditioner. The fresh air fan draws fresh air from the outside into the room to achieve fresh air exchange.

[0032] In the embodiment of the present application, the air conditioner can control the activation of the windless function and the fresh air function after receiving a specific instruction. Here, the specific instruction can be an instruction received by the air conditioner, and the received instruction can come from other electronic devices connected to the air conditioner; for example, the user can send an instruction to activate the fresh air function and the windless function to the air conditioner through the air conditioner remote control. Of course, the received instruction can also be an instruction generated by the air conditioner itself when the trigger condition is met.

[0033] The first time can be understood as the time when the air conditioner receives the instruction to turn on the windless function; the second time can be understood as the time when the air conditioner receives the instruction to turn on the fresh air function; the first time and the second time can be the same, or the first time and the second time can be different.

[0034] In actual applications, the air conditioner or electronic setting executes a function start operation, so that the air conditioner can obtain the first time when the windless function is turned on and the second time when the fresh air function is turned on.

[0035] Step 102: Obtain environmental data.

[0036] In the embodiments of the present application, environmental data can be understood as data related to the environment of the area where the air conditioner is located, and may include indoor temperature values, outdoor temperature values, and air quality index, etc.; the air quality index may include indoor carbon dioxide (CO2) concentration and PM2.5 (2.5-micrometer Particulate Matter) concentration; the fresh air fan ventilation of the air conditioner can change the indoor air quality, and the air supply volume of the indoor fan can change the indoor temperature.

[0037] Step 103: Based on the first time, the second time and the environmental data, control the first speed of the indoor fan and / or the second speed of the fresh air fan.

[0038] It can be understood that the first speed is the speed of the indoor fan, and the air conditioner can adjust the air supply volume by increasing or decreasing the speed of the indoor fan; the second speed is the speed of the fresh air fan, and the air conditioner can adjust the ventilation speed by increasing or decreasing the speed of the fresh air fan.

[0039] In an embodiment of the present application, the time when the fresh air function and the windless function of the air conditioner are respectively turned on can be determined based on the first time and the second time, so as to determine the current air supply demand; illustratively, the fresh air function is first turned on and runs for a period of time, and then the windless function is turned on to determine the current air supply demand with priority given to the windless function; based on the indoor temperature value, it can be determined whether the current temperature is within the appropriate temperature range, and based on the air concentration value, it can be determined whether the current indoor air quality is qualified; based on this, the first speed of the indoor fan and / or the second speed of the fresh air fan are controlled to change the indoor temperature and / or air quality.

[0040] From the above content, it can be seen that the control method of the air conditioner provided in the present application obtains the first time when the windless function is turned on, the second time when the fresh air function is turned on, and the environmental data to control the first speed of the indoor fan and / or the second speed of the fresh air fan, thereby solving the problem that the air conditioner cannot control the fresh air function and the windless function in a linked manner, and realizes the automatic control of the linked operation of the fresh air function and the windless function, making the operation of the air conditioner more intelligent.

[0041] In some embodiments of the present application, the environmental data includes an indoor temperature value. Step 103 controls the first speed of the indoor fan and / or the second speed of the fresh air fan based on the first time, the second time and the environmental data, which can be achieved by the following steps:

[0042] If the second time is earlier than the first time, and the time difference between the second time and the first time is greater than the preset time threshold, the second speed of the fresh air fan is controlled based on the indoor temperature value.

[0043] It is understandable that the preset time threshold can be set according to actual needs, and this application does not make specific limitations on this. For example, the preset time threshold can be 30 seconds, and the actual need can be the time interval used to distinguish air supply needs.

[0044] In the embodiment of the present application, the second time being earlier than the first time can be understood as the fresh air function being turned on first and the windless function being turned on later; the time difference between the second time and the first time being greater than the preset time threshold can be understood as the windless function being turned on after the fresh air function has been running for a period of time. At this time, the demand for the windless function takes priority, and the air conditioner can control the speed of the fresh air fan according to the indoor temperature value to adjust the indoor temperature.

[0045] In some embodiments of the present application, controlling the second speed of the fresh air fan based on the indoor temperature value includes:

[0046] Determine the indoor temperature value and the target temperature value to obtain a first determination result;

[0047] If the first judgment result indicates that the indoor temperature value is less than or equal to the target temperature value, reducing the second speed of the fresh air fan;

[0048] If the first judgment result indicates that the indoor temperature value is greater than the target temperature value, the second speed of the fresh air fan is maintained or the second speed of the fresh air fan is reduced.

[0049] It is understandable that the target temperature value can be set according to actual needs, and the present application does not make specific limitations on this; illustratively, the target temperature value can be a pre-set temperature value, and the actual demand can be a demand for rapid cooling.

[0050] In an embodiment of the present application, the size of the indoor temperature value and the target temperature value is judged to determine whether the indoor temperature has reached a preset temperature value; the first judgment result indicates that the indoor temperature value is less than or equal to the target temperature value, indicating that the indoor temperature has reached the preset temperature value. At this time, the rotation speed of the fresh air fan is reduced to avoid the heat and moisture introduced by the fresh air to cause fluctuations in the indoor temperature. The indoor fan can be operated at a low speed to make the wind feel lower; when the indoor temperature does not reach the preset temperature, the current rotation speed of the fresh air fan can be maintained or the rotation speed of the fresh air fan can be reduced according to actual conditions; for example: if the outdoor temperature is lower than the indoor temperature at this time, the rotation speed of the fresh air fan can be maintained to introduce new air to lower the indoor temperature; if the outdoor temperature is higher than the indoor temperature, the rotation speed of the fresh air fan can be reduced to reduce the impact of external heat on the indoor temperature.

[0051] In a realistic scenario, refer to Figure 2 As shown, T1 is the indoor temperature value, Ts is the target temperature value, TO is the fresh air inlet temperature value; JSX1 is the fresh air fan speed for the no-wind function, and JSX is the fresh air fan ventilation speed; no-wind interval 1 is the initial state of the no-wind function. The air supply and cooling capacity in this interval are lower than those in the normal state of the air conditioner. After the air conditioner runs in no-wind interval 1 for a period of time, it will automatically drop to no-wind interval 2. This interval is the final state of the no-wind function, and the wind feeling is lower than interval 1. The fresh air function is turned on first and then the no-wind function. At this time, the speed of the fresh air fan is JSX. The control steps of the air conditioner are as follows:

[0052] Step 201: When the air conditioner is in cooling mode, the windless function is turned on.

[0053] Step 202: If the fresh air function is turned on, execute step 204; if the fresh air function is not turned on, execute step 203.

[0054] Step 203: The fresh air is not turned on, and the windless function is controlled normally.

[0055] Step 204: Determine T1 and Ts; if T1>Ts, execute step 205; if T1≤Ts, execute step 207.

[0056] Step 205: If T1>Ts, determine TO and Ts; if TO≤T1, execute step 206; if TO>T1, execute step 207.

[0057] Step 206: T1>Ts and TO≤T1, there is no need to adjust the speed of the indoor fan. The fresh air fan is controlled to maintain the speed JSX to bring fresh air into the room and cool it down. Until T1 is lower than TO, step 207 can be executed to reduce the speed of the fresh air fan to JSX1. As the TO-T1 difference increases, the speed is lower. While the fresh air fan brings fresh air into the room, it can also reduce the impact of external heat on the room, ensuring comfort while reducing energy consumption.

[0058] Step 207: If T1≤Ts, it means that the indoor area temperature has reached the temperature set by the user. There is no need to adjust the speed of the indoor fan. The fresh air fan operates according to the windless windshield JSX1 to avoid the heat and moisture introduced by the fresh air, which may cause temperature fluctuations and condensation risks, and bring a bad experience to the user.

[0059] In some embodiments of the present application, the environmental data includes an air concentration value. Step 103 controls the first speed of the indoor fan and / or the second speed of the fresh air fan based on the first time, the second time and the environmental data, and can also be implemented by the following steps:

[0060] If the first time is earlier than the second time, and the time difference between the first time and the second time is greater than a preset time threshold, the first speed of the indoor fan and / or the second speed of the fresh air fan are controlled based on the air concentration value.

[0061] It can be understood that the air concentration value includes an air quality index, such as an indoor CO2 concentration value and a PM2.5 concentration value.

[0062] In the embodiment of the present application, the first time is earlier than the second time, which can be understood as the windless function is turned on first and the fresh air function is turned on later; the time difference between the second time and the first time is greater than the preset time threshold, which can be understood as the fresh air function is chosen to be turned on after the windless function has been running for a period of time. At this time, the demand for the fresh air function takes priority, and the air conditioner can control the speed of the fresh air fan according to the air concentration value to adjust the indoor air quality.

[0063] In some embodiments of the present application, the environmental data further includes an indoor temperature value and an outdoor temperature value, and controlling a first speed of the indoor fan and / or a second speed of the fresh air fan based on the air concentration value includes:

[0064] Determine the difference between the air concentration value and the target concentration value to obtain a second determination result;

[0065] If the second judgment result indicates that the air concentration value is less than the target concentration value, the second speed of the fresh air fan is reduced;

[0066] If the second judgment result indicates that the air concentration value is greater than or equal to the target concentration value, the first speed of the indoor fan is controlled based on the indoor temperature value and the outdoor temperature value.

[0067] It can be understood that the target concentration value can be set according to actual needs, and this application does not make any specific limitations on this; for example, the target concentration value can be the CO2 concentration standard value and PM2.5 concentration standard value that make the air quality qualified, and the actual demand can be to reduce the indoor CO2 and PM2.5 concentrations.

[0068] In the embodiment of the present application, the air concentration value and the target concentration value are judged to determine whether the indoor air concentration meets the standard; the second judgment result indicates that the air concentration value is less than the target concentration value, indicating that the indoor air concentration meets the standard at this time, and there is no need to improve the air quality, and the fresh air fan can operate at a low speed; the second judgment result indicates that the air concentration value is greater than or equal to the target concentration value, indicating that the air concentration does not meet the standard at this time, and the air quality needs to be improved. The fresh air function takes priority, but the introduction of new air by the fresh air will cause fluctuations in the indoor temperature. In this case, the speed of the indoor fan needs to be controlled according to the indoor temperature value and the outdoor temperature value to adjust the indoor temperature.

[0069] In some embodiments of the present application, controlling a first speed of an indoor fan based on an indoor temperature value and an outdoor temperature value includes:

[0070] If the outdoor temperature value is greater than the indoor temperature value, increase the first speed of the indoor fan;

[0071] If the outdoor temperature value is less than or equal to the indoor temperature value, the first speed of the indoor fan is increased or the indoor fan is stopped.

[0072] In the embodiment of the present application, the outdoor temperature value is greater than the indoor temperature value, and the operation of the fresh air fan will bring more hot air into the room. At this time, the air conditioner needs to enhance the cooling effect, and the indoor fan needs to increase the speed to provide a higher air supply volume; the outdoor temperature value is less than or equal to the indoor temperature value. The introduction of fresh air will not increase the indoor temperature, but may increase the risk of condensation. At this time, the speed of the indoor fan can be increased or the operation of the indoor fan can be stopped according to the actual situation.

[0073] In a realistic scenario, refer to Figure 3 As shown in the figure, CO2ref is the standard value of CO2 concentration, PM2.5ref is the standard value of PM2.5 concentration; T1L is the indoor air dew point temperature, B and C are the difference between the fresh air inlet temperature and the indoor air dew point temperature, and B>C≥0. The windless function is turned on first and then the fresh air function. At this time, the windless function is in interval 2. The control steps of the air conditioner are as follows:

[0074] Step 301: When the air conditioner is in cooling mode, turn on the fresh air function.

[0075] Step 302: Determine whether the no wind sense function is turned on; if the no wind sense function is turned on, execute step 304; if the no wind sense function is not turned on, execute step 303.

[0076] Step 303: The no-wind function is not enabled, and the fresh air fan runs at a speed of JSX.

[0077] Step 304: Determine indoor CO2 and PM2.5 concentrations.

[0078] Step 305: If the indoor CO2 and PM2.5 concentrations are lower than the determination values ​​CO2ref and PM2.5ref, it means that the actual demand for fresh air is not large at this time, and the fresh air fan is controlled to run at a speed of JSX1.

[0079] Step 306: If the indoor CO2 and PM2.5 concentrations are higher than or equal to the determination values ​​CO2ref and PM2.5ref, determine TO and T1; if TO>T1, execute step 307; if TO≤T1, execute step 308.

[0080] Step 307: When the indoor CO2 and PM2.5 concentrations are higher than or equal to the determination values CO2ref and PM2.5ref and TO > T1, there is no need to adjust the rotation speed of the fresh air fan. Control the windless function to return to interval 1, that is, increase the rotation speed of the indoor fan. After the air conditioner's windless function operates in interval 1 for a period of time, determine the indoor CO2 and PM2.5 concentrations again.

[0081] Step 308: When the indoor CO2 and PM2.5 concentrations are higher than or equal to the determination values CO2ref and PM2.5re and TO ≤ T1: Determine TO and T1L; if TO > T1L, execute Step 310; if TO ≤ T1L, execute Step 309.

[0082] Step 309: When the indoor CO2 and PM2.5 concentrations are higher than or equal to the determination values CO2ref and PM2.5re and TO ≤ T1L, introducing fresh air will not cause the indoor temperature to rise, but to reduce the risk of condensation, it is necessary to determine whether TO + B is less than T1L; if TO + B ≤ T1L, execute Step 312; if T1L < TO + B, execute Step 311.

[0083] Step 310: When TO > T1L, since there is no risk of condensation, there is no need to adjust the rotation speed of the fresh air fan, and control the indoor fan to maintain the current rotation speed.

[0084] Step 311: When TO ≤ T1L < TO + B, there is no need to adjust the rotation speed of the fresh air fan. At this time, the ventilation speed is relatively fast. To reduce the risk of condensation, increase the rotation speed of the indoor fan to make the windless function return to interval 1 and increase the air outlet speed.

[0085] Step 312: When TO + B ≤ T1L, since the risk of condensation is extremely high, the two functions cannot coexist at this time, the indoor fan stops running, and only the fresh air fan runs.

[0086] In some embodiments of the present application, the environmental data includes the indoor temperature value and the air concentration value. Step 103 controls the first rotation speed of the indoor fan and / or the second rotation speed of the fresh air fan based on the first time, the second time, and the environmental data, and can also be implemented through the following steps:

[0087] If the time difference between the second time and the first time is less than or equal to the preset time threshold, control the first rotation speed of the indoor fan and / or the second rotation speed of the fresh air fan based on the indoor temperature value and the air concentration value.

[0088] In the embodiments of the present application, the time difference between the second time and the first time being less than or equal to the preset time threshold can be understood as the user simultaneously turning on the fresh air function and the windless function. At this time, the air conditioner can control the rotation speed of the fresh air fan and / or the fresh air fan according to the air concentration value and the indoor temperature value to adjust the indoor air quality or temperature.

[0089] In some embodiments of the present application, controlling a first speed of an indoor fan and / or a second speed of a fresh air fan based on an indoor temperature value and an air concentration value includes:

[0090] Determine the indoor temperature value and the target temperature value to obtain a third determination result;

[0091] If the third judgment result indicates that the indoor temperature value is greater than the target temperature value, the second speed of the fresh air fan is maintained or the second speed of the fresh air fan is reduced;

[0092] If the third judgment result indicates that the indoor temperature value is less than or equal to the target temperature value, the first speed of the indoor fan and / or the second speed of the fresh air fan are controlled based on the indoor temperature value and the air concentration value.

[0093] In the embodiment of the present application, the indoor temperature value and the target temperature value are judged to determine whether the indoor temperature has reached the preset temperature value; the third judgment result indicates that the indoor temperature value is greater than the target temperature value, indicating that the indoor temperature has not reached the preset temperature value. At this time, the current speed of the fresh air fan can be maintained or the speed of the fresh air fan can be reduced according to the actual situation; for example, if the indoor air concentration is higher than or equal to the standard value, the speed of the fresh air fan can be maintained to improve the air quality; if the indoor air concentration is lower than the standard value, the speed of the fresh air fan can be reduced to give priority to the feeling of no wind. The third judgment result indicates that the indoor temperature value is less than or equal to the target temperature value, indicating that the indoor temperature has not reached the preset temperature value. The air conditioner can control the speed of the indoor fan and / or the speed of the fresh air fan according to the indoor temperature value and the air concentration value.

[0094] In some embodiments of the present application, the environmental data also includes an outdoor temperature value, and controlling the first speed of the indoor fan and / or the second speed of the fresh air fan based on the indoor temperature value and the air concentration value includes:

[0095] If the outdoor temperature value is greater than the indoor temperature value, increase the first speed of the indoor fan;

[0096] If the outdoor temperature value is less than or equal to the indoor temperature value, the air concentration value is determined to be greater than the target concentration value to obtain a fourth determination result;

[0097] If the fourth judgment result indicates that the air concentration value is less than the target concentration value, the second speed of the fresh air fan is reduced;

[0098] If the fourth judgment result indicates that the air concentration value is greater than or equal to the target concentration value, the first speed of the indoor fan is maintained or the first speed of the indoor fan is increased.

[0099] In the embodiment of the present application, when the indoor temperature value is greater than the target temperature value and the outdoor temperature value is greater than the indoor temperature value, it means that the indoor temperature has not reached the preset temperature value at this time, and there is no need to change the speed of the fresh air fan, and the air conditioner needs to increase the speed of the indoor fan to provide more cooling to cope with the heat brought by the fresh air; when the indoor temperature value is less than or equal to the target temperature value and the outdoor temperature value is less than or equal to the indoor temperature value, it means that the indoor temperature has reached the preset temperature value at this time, and the introduction of new air will not bring about a significant change in the indoor temperature. The air concentration value and the target concentration value are judged to determine the priority of the fresh air function or the priority of the no wind function; the fourth judgment result indicates that the air concentration value is less than the target concentration value, indicating that the indoor air quality meets the standard and there is little demand for improving the air quality. At this time, the speed of the fresh air fan can be reduced to save energy; the fourth judgment result indicates that the air concentration value is greater than or equal to the target concentration value, indicating that the indoor air quality does not meet the standard. At this time, the fresh air function can be prioritized, and the indoor fan can be maintained at the current speed or the speed can be increased.

[0100] In a realistic scenario, refer to Figure 4 As shown, when the air conditioner is in cooling state, both the no wind function and the fresh air function have been running for a period of time T. At this time, the fresh air fan runs at a speed of JSX, and the no wind function can be in interval 1 or interval 2. First, judge T1 and Ts. The control steps of the air conditioner are as follows:

[0101] Step 401: Turn on the fresh air function and the windless function at the same time.

[0102] Step 402: Both the windless function and the fresh air function operate for a period of time T.

[0103] Step 403: Determine T1 and Ts; if T1>Ts, execute step 404 to determine whether the CO2 and PM2.5 concentrations are lower than the determination values ​​CO2ref and PM2.5ref. If yes, execute step 405, otherwise execute step 406; if T1≤Ts, execute step 407.

[0104] Step 404: If T1>Ts and the concentrations of CO2 and PM2.5 are lower than the determination values ​​CO2ref and PM2.5ref, then execute step 405; if T1>Ts and the concentrations of CO2 and PM2.5 are higher than or equal to the determination values ​​CO2ref and PM2.5ref, then execute step 406.

[0105] Step 405: Control the speed of the fresh air fan to run at JSX1, and the windless function runs in interval 1. After the two functions run for time t1, the indoor CO2 and PM2.5 concentrations are determined again.

[0106] Step 406: There is no need to adjust the rotation speeds of the fresh air fan and the indoor fan. T1 and Ts are determined again after the two functions have been running for a period of time.

[0107] Step 407: When T1≤Ts, determine whether TO is less than or equal to T1, if so, execute step 409; otherwise, execute 408.

[0108] Step 408: T1≤Ts and TO>T1, control the fresh air fan to run at a speed of JSX1, and the windless function runs in interval 1 to provide greater cooling to cope with the heat brought in by the outdoor fresh air, and avoid indoor temperature fluctuations caused by fresh air circulating indoor air. After the two functions have been running for a period of time, TO and T1 are determined again.

[0109] Step 409: When T1≤Ts and TO≤T1, determine whether the CO2 and PM2.5 concentrations are lower than the determination values ​​CO2ref and PM2.5ref; if yes, proceed to step 410; if no, proceed to step 411.

[0110] Step 410: The CO2 and PM2.5 concentrations are lower than the judgment values ​​CO2ref and PM2.5ref, and the speed of the fresh air fan is controlled to run at JSX1, and the no-wind function runs in interval 2.

[0111] Step 411: If the concentrations of CO2 and PM2.5 are higher than or equal to the determination values ​​CO2ref and PM2.5ref, determine whether TO+C is less than or equal to T1L; if so, execute step 408; otherwise, execute step 412.

[0112] Step 412: TO+C>T1L, the fresh air fan runs at the speed JSX, and the windless function is controlled to be in interval 2.
