[0009] S4: If the user actively adjusts the operation mode and operation parameters of the air conditioner after step S3, the operation mode and operation parameters under the current physiological state information, personal characteristic information and environmental information are recorded, and the air conditioner is controlled when the user uses it next time;

[0010] S5: After each preset first time interval, the perceived comfort of each user is obtained through the historical usage record of each user, and the cooling capacity of the air conditioner is adjusted based on the perceived comfort of one or more users in the room where the air conditioner is located.

[0011] Preferably, in step S3, controlling the start and stop of the operation mode of the air conditioner according to the physiological state information and the environmental information includes:

[0012] If the temperature value is outside the preset comfortable temperature range, the air conditioner is controlled to start the temperature adjustment mode to adjust the indoor temperature until the temperature value is within the preset comfortable temperature range, and then the temperature adjustment mode is stopped;

[0013] If the humidity value is outside the preset comfortable humidity range, the air conditioner is controlled to start the humidity adjustment mode to adjust the indoor humidity until the humidity value is within the preset comfortable humidity range, and then the humidity adjustment mode is stopped;

[0014] If the user's heart rate is higher than the preset normal heart rate range, when both the temperature and humidity values ​​are not within the comfort range, the temperature adjustment mode is prioritized; if the user's heart rate is lower than the preset normal heart rate range, when both the temperature and humidity values ​​are not within the comfort range, the humidity adjustment mode is prioritized.

[0015] Furthermore, in step S3, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0016] S310: Obtaining a reference age and a corresponding comfortable temperature range;

[0026] S322: Control the air conditioner to operate in humidity adjustment mode, and adjust the indoor humidity value to the comfortable humidity range calculated in step S321.

[0027] Furthermore, in step S3, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0028] S331: Get current season information;

[0029] S332: If the current season is spring or summer, the comfortable temperature range is adjusted in combination with the user's gender, and the relationship is satisfied:

[0030] T′=T+k 性 +s1;

[0031] Where T represents the upper or lower limit of the comfortable temperature range, T′ represents the upper or lower limit of the adjusted comfortable temperature range, k 性 represents the gender adjustment coefficient, s1 represents the adjustment coefficient of spring or summer;

[0032] S333: If the current season is autumn or winter, the comfortable temperature range is adjusted in combination with the user's gender, and the relationship is satisfied:

[0033] T′=T+k 性 -s2;

[0034] Where T represents the upper or lower limit of the comfortable temperature range, T′ represents the upper or lower limit of the adjusted comfortable temperature range, k 性 represents the adjustment coefficient for gender, and s2 represents the adjustment coefficient for autumn or winter;

[0035] S334: Control the air conditioner to operate in temperature adjustment mode, and adjust the indoor temperature value to the comfortable temperature range calculated in step S333.

[0036] Preferably, in step S3, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0037] Calculate the user's BMI data based on the user's height and weight;

[0038] If the user's BMI data is within the thin range, it is determined whether the user's heart rate is within the preset normal heart rate range. If so, the air conditioner's wind speed is adjusted to the second gear. If the user's heart rate is higher than the normal heart rate range, the air conditioner's wind speed is adjusted to the third gear. If the user's heart rate is lower than the normal heart rate range, the air conditioner's wind speed is adjusted to the first gear.

[0039] If the user's BMI data is within the normal body range, it is determined whether the user's heart rate is within the preset normal heart rate range. If so, the air conditioner's wind speed is adjusted to the third gear. If the user's heart rate is higher than the normal heart rate range, the air conditioner's wind speed is adjusted to the fourth gear. If the user's heart rate is lower than the normal heart rate range, the air conditioner's wind speed is adjusted to the second gear.

[0040] If the user's BMI data is within the obesity range, it is determined whether the user's heart rate is within the preset normal heart rate range. If so, the wind speed of the air conditioner is adjusted to the fourth gear. If the user's heart rate is higher than the normal heart rate range, the wind speed of the air conditioner is adjusted to the fifth gear. If the user's heart rate is lower than the normal heart rate range, the wind speed of the air conditioner is adjusted to the third gear.

[0041] Preferably, in step S3, it also includes identifying the sweating degree of the user;

[0042] If the user is in a state of slight sweating or no sweating, the angle between the air outlet direction of the air conditioner and the user is adjusted to within a first angle range;

[0043] If the user is in a moderate sweating state, the angle between the air outlet direction of the air conditioner and the user is adjusted to within a second angle range;

[0044] If the user is in a state of heavy sweating, the angle between the air outlet direction of the air conditioner and the user is adjusted to within a third angle range;

[0045] Among them, the lower limit value of the first angle range is greater than the upper limit value of the second angle range, and the lower limit value of the second angle range is greater than the upper limit value of the third angle range.

[0046] Preferably, in step S4, if the user actively adjusts the operation mode and operation parameters of the air conditioner within a preset second time interval after step S3, the historical operation mode and historical operation parameters under the current physiological state information, personal characteristic information and environmental information are recorded;

[0047] When the user uses the air conditioner next time, the user controls the air conditioner using the historical operation mode and historical operation parameters under the same physiological state information, personal characteristic information or environmental information.

[0048] Preferably, the environmental information also includes the space capacity of the room where the air conditioner is located;

[0049] Step S5 comprises the steps of:

[0050] S51: Obtaining the physical comfort of the current user under the current environment information in the historical usage record;

[0051] S52: If the acquisition fails, the comfort level of the current user under the current environment information is obtained by combining the historical usage records of the air conditioner by other users under the current environment information;

[0052] S53: adjusting the cooling capacity of the air conditioner according to the space capacity of the room where the air conditioner is located and the physiological state information of the user to achieve the user's perceived comfort under the current environmental information;

[0053] S54: After each preset first time interval, the current environment information is obtained. If the environment information changes, steps S51 to S53 are executed to maintain the user's physical comfort.

[0054] Further, in step S5, if there are two people in the room where the air conditioner is located:

[0055] Determine whether the perceived comfort of two persons is similar. If so, adjust the cooling capacity of the air conditioner to meet the perceived comfort of one of them.

[0056] If they are not similar, the cooling capacity of the air conditioner is adjusted to adjust the user's perceived comfort to a middle value between the perceived comfort of the two.

[0057] If there are more than two people in the room where the air conditioner is located:

[0058] If there are multiple people with similar perceived comfort, the cooling capacity of the air conditioner is adjusted within a third time interval to satisfy the perceived comfort of the multiple people, and within a fourth time interval, the cooling capacity of the air conditioner is adjusted to adjust the perceived comfort of the user to a maximum value or a minimum value among the perceived comfort of the multiple people;

[0059] If there are not multiple people with similar perceived comfort, the cooling capacity of the air conditioner is adjusted to adjust the user's perceived comfort to a median value between the maximum and minimum values ​​of the perceived comfort of the multiple people.

[0060] One of the above technical solutions has the following advantages or beneficial effects:

[0061] By identifying the user's physiological state information and personal characteristic information, this solution can more accurately understand the user's comfort needs, further refine the adjustment strategy, and provide a personalized comfort experience. It can automatically start and stop and adjust the air conditioner operation mode according to real-time environmental information, avoiding unnecessary energy waste. At the same time, by adjusting the operation parameters in a personalized way, it can ensure that while meeting the user's comfort needs, energy consumption is reduced as much as possible to achieve the goal of energy conservation and environmental protection. At the same time, the air conditioner has the ability to learn, and can record the user's active adjustment behavior of the air conditioner operation mode and parameters, and continuously optimize its own control strategy based on this. As the use time increases, the air conditioner will better understand the user's preferences and habits, thereby providing more intimate and efficient services. The cooling capacity is adjusted through the feedback of historical usage records, and the cooling capacity is adjusted in time to meet the needs of all users. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0069] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0070] With the continuous improvement of technology and people's living standards, smart home appliances are constantly developing, and smart ecology has gradually become an important indicator for people to choose home appliances. The popularization of smart home appliances is closely related to the interaction with mobile phones, which brings convenience and efficiency improvement to users. At present, the air-conditioning control system has the characteristics of unintelligent control mode, inconvenient control method and single control mode. Some air conditioners with automatic control functions on the market often only judge the corresponding cooling and heating mode according to the ambient temperature. The automatic control method has simple logic and is difficult to adapt to the user's growing intelligent needs. At the same time, this automatic control function does not take into account the user's comfort needs, and the user experience is not good.

[0071] Therefore, an automatic control method of an air conditioner is proposed. Figure 1 As shown, a preferred embodiment of the present application includes the steps of:

[0072] S1: Identify the user and obtain the user's physiological status information and personal characteristic information. The physiological status information includes heart rate, and the personal characteristic information includes age, gender, height and weight;

[0073] In this step, the personal characteristic information may be input or recorded by the user in advance, and the physiological state information is collected in real time. In this embodiment, a fingerprint unlocking module or a face recognition module may be set on the remote control corresponding to the air conditioner. The remote control obtains the user's personal characteristic information, such as the user's basic information, including age, gender, height, weight, etc., through fingerprint unlocking, and a physiological state acquisition module may be set on the remote control to collect the user's physiological state information, including but not limited to the user's heart rate, body temperature, blood pressure and other physiological indicators. User identity recognition can ensure the accuracy and personalization of information. For example, there may be multiple users in a family, and each user has different needs and preferences, which need to be distinguished when adjusting the air conditioner. The acquisition of physiological state information can understand the user's health status in real time, so as to make corresponding adjustments. If the user is exercising or feels hot, the air conditioner may need to reduce the indoor temperature faster. The user's comfort range for temperature can be determined based on personal characteristic information such as the user's age, gender and other characteristics. For example, women and men may have different comfort needs under the same environmental conditions.

[0074] S2: Collecting the indoor environment information of the air conditioner, wherein the indoor environment information includes temperature and humidity values;

[0075] In this step, a temperature sensor and a humidity sensor can be set inside the air conditioner to measure the temperature and humidity values ​​in the room where the air conditioner is located. The collection of environmental information can provide real-time understanding of the indoor environment and assist in the intelligent adjustment of the air conditioner. The temperature and humidity data are used to determine whether the current environment requires a change in operating mode.

[0076] S3: controlling the start and stop of the operation mode of the air conditioner according to the physiological state information and the environmental information, and adjusting the operation parameters of the operation mode according to the personal characteristic information of the user;

[0077] Specifically, the operation mode of the air conditioner can be a temperature adjustment mode, a humidity adjustment mode, a power saving mode, a sleep mode, etc. When the physiological state changes and the environmental information changes, the air conditioner also needs to be adjusted accordingly. The air conditioner needs to start or stop a certain mode to start or end the adjustment. For example, if the temperature of the environment is higher than the indoor comfortable temperature range, the air conditioner needs to start the temperature adjustment mode. When determining the operation mode of the air conditioner, it is necessary to adjust the operation parameters of the operation mode in combination with the user's personal characteristic information. For example, when setting the temperature, users of different ages have different temperature perception abilities, so different comfortable temperature ranges need to be set for users of different ages. In addition, for older users, they may suffer from rheumatic symptoms, so the air conditioner needs to control the indoor humidity to a lower level. It is worth noting that when the user enters the room after exercising outdoors or exercises indoors, if the user's heart rate is at a high level or sweats, the air outlet speed or air outlet direction of the air conditioner can be adjusted to improve the user experience.

[0078] S4: If the user actively adjusts the operating mode and operating parameters of the air conditioner after step S3, the operating mode and operating parameters under the current physiological state information, personal characteristic information and environmental information are recorded, and the air conditioner is controlled when the user uses it next time.

[0079] After automatically controlling the air conditioner, the user may control the air conditioner again due to experience problems or physical discomfort. The operating parameters adjusted by the user are the most suitable operating parameters for the user. Therefore, by recording this adjustment, the specific operating mode (such as cooling or heating) selected by the user and its set values ​​(such as temperature and wind speed) can be recorded. Next time when a user of the same age, height or weight uses the air conditioner at the same temperature, the air conditioner can directly adjust the operating mode and operating parameters according to the record, reducing the need for manual adjustment by the user while providing a personalized comfort experience.

[0080] S5: After each preset first time interval, the perceived comfort of each user is obtained through the historical usage record of each user, and the cooling capacity of the air conditioner is adjusted based on the perceived comfort of one or more users in the room where the air conditioner is located.

[0081] After the user adjusts the air conditioner or the air conditioner automatically adjusts its operating mode and operating parameters, if the user does not continue to adjust it within a certain period of time, the air conditioner will consider that the current operating mode and operating parameters have met the user's needs, and the air conditioner will record the user's air conditioning settings, operating modes, etc. under different environmental conditions. The air conditioner will dynamically adjust the cooling capacity based on real-time environmental information (temperature, humidity) and the user's perceived comfort evaluation results. For example, when the ambient temperature rises and the user reports sweating, the air conditioner will automatically increase the cooling capacity. There may be multiple users in the space where the air conditioner is located, so it is necessary to dynamically adjust the cooling capacity of the air conditioner based on the perceived comfort of multiple users to meet the needs of all users as much as possible.

[0082] Preferably, in step S3, controlling the start and stop of the operation mode of the air conditioner according to the physiological state information and the environmental information includes:

[0083] If the temperature value is outside the preset comfortable temperature range, the air conditioner is controlled to start the temperature adjustment mode to adjust the indoor temperature until the temperature value is within the preset comfortable temperature range, and then the temperature adjustment mode is stopped;

[0084] If the humidity value is outside the preset comfortable humidity range, the air conditioner is controlled to start the humidity adjustment mode to adjust the indoor humidity until the humidity value is within the preset comfortable humidity range, and then the humidity adjustment mode is stopped;

[0085] If the user's heart rate is higher than the preset normal heart rate range, when both the temperature and humidity values ​​are not within the comfort range, the temperature adjustment mode is prioritized; if the user's heart rate is lower than the preset normal heart rate range, when both the temperature and humidity values ​​are not within the comfort range, the humidity adjustment mode is prioritized.

[0086] Specifically, the comfortable temperature range needs to be set based on multiple elements. The comfortable temperature range can be determined according to the season, environmental factors and the user's health status. In the early stage of the user using the air conditioner, the air conditioner controls the indoor temperature within the general comfortable temperature range, and the comfortable temperature range can be changed according to different users later. For the indoor temperature value, if it is outside the preset comfortable temperature range, the air conditioner needs to turn on the temperature adjustment mode to adjust the indoor temperature. When the temperature value is within the preset comfortable temperature range, the temperature adjustment is stopped. Similarly, for the indoor humidity value, if it is outside the preset comfortable humidity range, the air conditioner needs to turn on the humidity adjustment mode to adjust the indoor humidity. When the humidity value is within the preset comfortable humidity range, the humidity adjustment is stopped.

[0087] It is worth noting that when the user's heart rate is higher than the preset normal heart rate range, it usually means that the body may be in a state of tension or high load. At this time, the regulation of body temperature becomes particularly important, because during exercise or tension, the human body will generate more heat. If the ambient temperature is too high or too low, it will further increase the body's heat load or cold stress, thereby affecting the heart rate and overall health. In a high temperature environment, the body will activate a series of physiological mechanisms to dissipate heat, such as sweating and increasing skin blood flow. These processes will increase the burden on the heart and cause the heart rate to rise. Therefore, lowering the ambient temperature is an effective way to alleviate this burden. When the heart rate is already high, turning on the temperature adjustment mode first can help the body return to a suitable body temperature range more quickly, thereby reducing the burden on the heart and lowering the heart rate.

[0088] In a high humidity environment, the human body's heat dissipation efficiency is reduced, and it is easy to feel stuffy and uncomfortable. This discomfort may affect the user's mood and overall health, and then have an indirect impact on the heart rate. By reducing the humidity of the environment, the human body's heat dissipation efficiency can be improved, making people feel more refreshed and comfortable. When the heart rate is high, priority is given to temperature regulation to reduce the burden on the heart; when the heart rate is low, priority is given to humidity regulation to improve comfort and health, which helps to better meet the personalized needs of users and improve user experience.

[0089] In another embodiment, in step S3, Figure 2 As shown, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0090] S310: Obtaining a reference age and a corresponding comfortable temperature range;

[0091] S311: Based on the comfortable temperature range, the upper limit and the lower limit of the user's comfortable temperature range are calculated according to the difference between the user's age and the reference age, and the relationship is satisfied:

[0092]

[0093] Where T represents the upper or lower limit of the comfortable temperature range, T′ represents the upper or lower limit of the adjusted comfortable temperature range, k 温 represents the temperature regulation coefficient, a 用 Indicates the user's age, a 参 represents the reference age;

[0094] S312: Control the air conditioner to operate in a temperature adjustment mode, and adjust the indoor temperature to the comfortable temperature range calculated in step S311.

[0095] Specifically, different ages have different sensitivities and perceptions of temperature. Therefore, in step S310, a reference age (reference age) is first determined. The reference age should be representative and reflect the general preference of most people for comfortable temperature in this age group, such as 30 years old. A standard comfortable temperature range is set for this age, such as 20-22°C. When the user is 40 years old, the temperature adjustment coefficient k is 温 is 1, so the user's comfortable temperature range is 20.45-22.45℃. Then the air conditioner turns on the temperature adjustment mode to adjust the indoor temperature to between 20.45-22.45℃. The temperature adjustment coefficient k 温 It can be adjusted according to seasons, environment and other factors.

[0096] In step S3, if Figure 3 As shown, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0097] S320: Obtaining a reference age and a corresponding comfortable humidity range;

[0098] S321: Based on the comfortable humidity range, the upper limit and the lower limit of the user's comfortable humidity range are calculated according to the difference between the user's age and the reference age, and the relationship is satisfied:

[0099]

[0100] Where H represents the upper or lower limit of the comfortable humidity range, H′ represents the upper or lower limit of the comfortable humidity range after adjustment, and k 温 represents the humidity adjustment coefficient, a 用 Indicates the user's age, a 参 represents the reference age;

[0101] S322: Control the air conditioner to operate in humidity adjustment mode, and adjust the indoor humidity value to the comfortable humidity range calculated in step S321.

[0102] Specifically, people of different ages feel differently about indoor humidity. For example, older users may suffer from rheumatism, so high humidity will have an adverse effect on users. When the air humidity is too high, water molecules in the air will adhere to the surface of human skin, causing the skin to be sticky. If the respiratory tract is sensitive, breathing in high-humidity air may cause sneezing, runny nose, coughing and other symptoms. When the air humidity is too low, the water in the human body evaporates too quickly, which may cause dehydration such as tight skin, sore throat, and thirst. The low humidity environment will quickly evaporate the liquid in the respiratory mucosa, making it dry and fragile, reducing its ability to remove foreign matter and increasing the risk of bacterial and viral invasion. Therefore, the user's comfortable humidity range can be calculated based on the difference between age and reference age. For example, if the reference age is 30 years old, the user's age a 甲 For 50 years old, the humidity adjustment factor k 温 The comfortable humidity range is 48%-68%, and the adjusted comfortable humidity range is 52%-60%.

[0103] In step S3, if Figure 4 As shown, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0104] S331: Get current season information;

[0105] S332: If the current season is spring or summer, the comfortable temperature range is adjusted in combination with the user's gender, and the relationship is satisfied:

[0106] T′=T+k 性 +s1;

[0107] Where T represents the upper or lower limit of the comfortable temperature range, T′ represents the upper or lower limit of the adjusted comfortable temperature range, k 性 represents the gender adjustment coefficient, s1 represents the adjustment coefficient of spring or summer;

[0108] S333: If the current season is autumn or winter, the comfortable temperature range is adjusted in combination with the user's gender, and the relationship is satisfied:

[0109] T′=T+k 性 -s2;

[0110] Where T represents the upper or lower limit of the comfortable temperature range, T′ represents the upper or lower limit of the adjusted comfortable temperature range, k 性 represents the adjustment coefficient for gender, and s2 represents the adjustment coefficient for autumn or winter;

[0111] S334: Control the air conditioner to operate in temperature adjustment mode, and adjust the indoor temperature value to the comfortable temperature range calculated in step S333.

[0112] Specifically, by considering the personal characteristics of seasons and user gender, more precise comfort temperature adjustment can be achieved. In spring and summer, users tend to wear short sleeves, while in autumn and winter, users tend to wear long sleeves or multiple pieces of clothing. Therefore, the comfort temperature range in autumn and winter is lower than that in spring and summer. In addition, there are significant differences in the perception of temperature between men and women. Women are generally more sensitive to cold. By introducing the gender adjustment coefficient, the comfort temperature range can be personalized according to the different physical needs of men and women, which helps to improve user satisfaction and comfort, while also improving energy efficiency and reducing energy waste. This personalized adjustment method makes the operation of the air conditioner more intelligent. For example, the initial comfort temperature range is 20°-25°C, and the gender adjustment coefficient k 性 It is 0.5, that is, the comfortable temperature range for women is 0.5℃ higher than that for men. The adjustment coefficient s1 in spring is 2, then the comfortable temperature range for girls in spring is 22.5℃-27.5℃. If the adjustment coefficient s2 in winter is 1, then the comfortable temperature range for girls in winter is 19.5℃-24.5℃.

[0113] Furthermore, in step S3, adjusting the operating parameters of the operating mode according to the user's personal characteristic information includes the following steps:

[0114] Calculate the user's BMI data based on the user's height and weight;

[0115] If the user's BMI data is within the thin range, it is determined whether the user's heart rate is within the preset normal heart rate range. If so, the air conditioner's wind speed is adjusted to the second gear. If the user's heart rate is higher than the normal heart rate range, the air conditioner's wind speed is adjusted to the third gear. If the user's heart rate is lower than the normal heart rate range, the air conditioner's wind speed is adjusted to the first gear.

[0116] If the user's BMI data is within the normal body range, it is determined whether the user's heart rate is within the preset normal heart rate range. If so, the air conditioner's wind speed is adjusted to the third gear. If the user's heart rate is higher than the normal heart rate range, the air conditioner's wind speed is adjusted to the fourth gear. If the user's heart rate is lower than the normal heart rate range, the air conditioner's wind speed is adjusted to the second gear.

[0117] If the user's BMI data is within the obesity range, it is determined whether the user's heart rate is within the preset normal heart rate range. If so, the wind speed of the air conditioner is adjusted to the fourth gear. If the user's heart rate is higher than the normal heart rate range, the wind speed of the air conditioner is adjusted to the fifth gear. If the user's heart rate is lower than the normal heart rate range, the wind speed of the air conditioner is adjusted to the third gear.

[0118] Specifically, each person's physical condition and sensitivity to the environment are different. By considering the user's BMI (body mass index) and heart rate and other physiological indicators, the air conditioner's wind speed can be adjusted more accurately, thereby providing users with a personalized comfort experience. For example, for users with a thinner body, they may feel cold more easily, so the air conditioner's wind speed will be lowered accordingly; while for obese users, stronger wind force is required to achieve the same comfort. Heart rate is one of the important indicators reflecting human health. By monitoring the user's heart rate and combining it with BMI data, the user's physical condition can be preliminarily judged. For example, if the user's heart rate is abnormally high, it means that the user is doing strenuous exercise, has finished strenuous exercise, or is in a tense state. At this time, increasing the air conditioner's wind speed can help the user cool down quickly. If the heart rate is low, it means that the user is resting or relaxing. At this time, reducing the wind speed can prevent the user from feeling uncomfortable due to excessive blowing.

[0119] Furthermore, in step S3, it also includes identifying the sweating degree of the user;

[0120] If the user is in a state of slight sweating or no sweating, the angle between the air outlet direction of the air conditioner and the user is adjusted to within a first angle range;

[0121] If the user is in a moderate sweating state, the angle between the air outlet direction of the air conditioner and the user is adjusted to within a second angle range;

[0122] If the user is in a state of heavy sweating, the angle between the air outlet direction of the air conditioner and the user is adjusted to within a third angle range;

[0123] Among them, the lower limit value of the first angle range is greater than the upper limit value of the second angle range, and the lower limit value of the second angle range is greater than the upper limit value of the third angle range.

[0124] Specifically, when the user is in a state of slight sweating or no sweating, the angle between the air outlet direction and the user is adjusted to the first angle range (larger angle), which can reduce the user's direct blowing and avoid catching a cold. If the user is in a state of moderate sweating, the angle is adjusted to the second angle range (moderate angle), which can help the user dissipate heat faster and reduce discomfort while maintaining a certain degree of comfort. When the user sweats a lot, the angle is adjusted to the third angle range (smaller angle), which can more effectively deliver cold air to the user, help the user cool down quickly, and reduce the discomfort caused by high temperature and heavy sweating. In this embodiment, the first angle range is 60°-90°, the second angle range is 30°-60°, and the third angle range is 0°-30°. The intelligent adjustment method not only improves the use efficiency of the air conditioner, but also allows the user to automatically adjust the wind direction according to the actual situation of the user without the user manually adjusting the wind direction, providing more intimate and personalized services.

[0125] Further, in step S4, if the user actively adjusts the operation mode and operation parameters of the air conditioner within the preset second time interval after step S3, the historical operation mode and historical operation parameters under the current physiological state information, personal characteristic information and environmental information are recorded;

[0126] When the user uses the air conditioner next time, the user controls the air conditioner using the historical operation mode and historical operation parameters under the same physiological state information, personal characteristic information or environmental information.

[0127] Specifically, after step S3, if the user actively adjusts the operation mode and operation parameters of the air conditioner within the preset time interval (such as adjusting the temperature, wind speed, wind direction, etc.), the air conditioner regards this behavior as the user's dissatisfaction with the current settings or the expression of specific needs. The air conditioner records the physiological state information (such as heart rate, etc.), personal characteristic information (such as age, gender, preferences, etc.) and environmental information (such as indoor temperature, humidity, light, etc.) at the current moment. At the same time, it will also record the operation mode and operation parameters before the user's adjustment as the historical operation mode and historical operation parameters, and use this as the user's preference for the operation mode and parameters of the air conditioner. When the user uses the air conditioner next time, if one or more of the same physiological state information, personal characteristic information or environmental information matches the previously recorded information, it will automatically recommend or directly apply the previously recorded historical operation mode and historical operation parameters to control the air conditioner. Through intelligent recommendation and automatic setting, the tediousness of manual adjustment by users is reduced, and the convenience and satisfaction of use are improved; the air conditioner can customize the operation mode and parameters of the air conditioner according to the user's personal characteristics and preferences, and provide more personalized services.

[0128] Preferably, the environmental information also includes the space capacity of the room where the air conditioner is located;

[0129] Step S5 comprises the steps of:

[0130] S51: Obtaining the physical comfort of the current user under the current environment information in the historical usage record;

[0131] The air conditioner extracts user usage data that matches the current environmental information (such as temperature and humidity) from historical usage records. The purpose is to understand the user's comfort level in similar environments through historical data.

[0132] S52: If the acquisition fails, the comfort level of the current user under the current environment information is obtained by combining the historical usage records of the air conditioner by other users under the current environment information;

[0133] If S51 fails to obtain, the air conditioner will analyze the historical usage records of other users under similar environmental conditions, find out users with similar characteristics to the current user, and infer the physical comfort required by the current user in the current environment through the physical data of these similar users.

[0134] S53: adjusting the cooling capacity of the air conditioner according to the space capacity of the room where the air conditioner is located and the physiological state information of the user to achieve the user's perceived comfort under the current environmental information;

[0135] The air conditioner will comprehensively consider the spatial capacity (volume) of the room where the air conditioner is located and the user's physiological state, such as sweating degree and heart rate. For example, in a living room, the temperature detection device of the air conditioner monitors that the current temperature is 30°C and the user's desired comfort temperature is 24°C. According to the room volume and the user's activity level, the air conditioner calculates the required cooling capacity to be 3000 watts. At this time, it detects that the user's sweating degree is slight sweating, so the air conditioner sets the cooling capacity to 3300 watts, and the air conditioner starts cooling at this power.

[0136] S54: After each preset first time interval, the current environment information is obtained. If the environment information changes, steps S51 to S53 are executed to maintain the user's physical comfort.

[0137] The first preset time interval is used to periodically obtain environmental information, including temperature, humidity or air flow rate, etc. Once an environmental change is detected, the process of S51-S53 will be returned to adjust the cooling output to maintain the target temperature of 24°C to maintain the user's physical comfort.

[0138] Further, in step S5, if there are two people in the room where the air conditioner is located:

[0139] Determine whether the perceived comfort of two persons is similar. If so, adjust the cooling capacity of the air conditioner to meet the perceived comfort of one of them.

[0140] If they are not similar, the cooling capacity of the air conditioner is adjusted to adjust the user's perceived comfort to a middle value between the perceived comfort of the two.

[0141] If there are more than two people in the room where the air conditioner is located:

[0142] If there are multiple people with similar perceived comfort, the cooling capacity of the air conditioner is adjusted within a third time interval to satisfy the perceived comfort of the multiple people, and within a fourth time interval, the cooling capacity of the air conditioner is adjusted to adjust the perceived comfort of the user to a maximum value or a minimum value among the perceived comfort of the multiple people;

[0143] If there are not multiple people with similar perceived comfort, the cooling capacity of the air conditioner is adjusted to adjust the user's perceived comfort to a median value between the maximum and minimum values ​​of the perceived comfort of the multiple people.

[0144] Specifically, the air conditioner is equipped with a sensor to recognize the presence of the user and the identity of the user, and obtain the user's perceived comfort from the historical usage records. For example, when there are two users in the room where the air conditioner is located, if the perceived comfort of the two people is less than or equal to 1, it is considered that their perceived comfort is similar, and the cooling capacity of the air conditioner can be adjusted to meet the needs of one of them. When the perceived comfort of the two is not similar, assuming that the perceived comfort of user a is 25 and the perceived comfort of user b is 19, the air conditioner needs to adjust the cooling capacity of the air conditioner so that their perceived comfort is 22, balancing the needs of all parties and avoiding making any user feel too uncomfortable. The center value adjustment guides the air conditioner to operate at a compromise point, which helps to reduce energy waste caused by over-adjustment. In addition, if there are multiple people in the room where the air conditioner is located, for example, 3 people, namely user A, user B, and user C, whose perceived comfort levels are 26, 26, and 21, respectively, since the perceived comfort levels of user A and user B are similar, the cooling capacity of the air conditioner is adjusted first to make the perceived comfort level of the user 26, and the air conditioner is adjusted at intervals to make the perceived comfort level of the user 21, and then adjusted back to 26 after different time intervals. If the perceived comfort levels of user A, user B, and user C are 26, 23, and 18, respectively, the median value 22 of the maximum and minimum values ​​is set as the target value of the perceived comfort level that the air conditioner needs to adjust the cooling capacity to adjust, and the air conditioner is adjusted first to meet their common needs, and the needs of the majority of people are met first. At the same time, in order to take care of the experience of everyone, the air conditioner will adjust the comfort levels of the remaining users within another time interval.
