Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner control, and in particular to an air conditioner comfort control method based on historical habits. Background Art

[0002] With technological advancements and improved living standards, air conditioners have become an indispensable appliance in modern homes and offices. Traditional air conditioner control often relies on users manually setting parameters such as temperature, air speed, and direction. This method is not only cumbersome but also fails to meet the personalized comfort needs of different users at different times and in different environments.

[0003] Although there are some smart air-conditioning products on the market that can automatically adjust the operating status of the air conditioner by learning the user's usage habits, most of these products only consider the usage habits of a single user or in a fixed scenario, and do not take into account shared spaces with multiple people and complex and changing environmental factors. Summary of the Invention

[0004] In response to the above-mentioned defects, the purpose of the present invention is to propose an air-conditioning comfort control method based on historical habits, which aims to automatically adjust the operating mode and operating parameters of the air-conditioning by analyzing the user's historical usage data and combining multiple factors such as current environmental information, number of users, time period and seasonal changes to meet the personalized comfort needs of different users in different environments.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] An air conditioning comfort control method based on historical habits, the air conditioning comfort control method comprising the following steps:

[0007] S1: Obtaining corresponding historical usage data of the air conditioner according to user permissions, wherein the historical usage data includes the operating mode, operating parameters, and corresponding time period of the air conditioner;

[0008] S2: Determine whether the historical usage data can meet all comfort requirements based on the number of users in the air-conditioned room, environmental information, and / or the time period of the current time. If so, the air conditioner is operated according to the corresponding historical usage data within the current time period. If not, proceed to step S3.

[0009] S3: Control the on / off of the air conditioning operation mode and adjust the operation parameters within the corresponding time period according to the missing comfort needs.

[0010] Preferably, if the corresponding air conditioner historical usage data cannot be obtained in step S1, the historical usage data of other users are counted to find the historical usage data with the most usage times in the time period of the current time;

[0011] If the statistical quantity of the historical use data of other users is 0 or the use times of different historical use data are all the same, the air conditioner operates according to the preset default operation mode and default operation parameter.

[0012] Preferably, the operation mode includes a temperature adjustment mode, a ventilation mode and a humidity adjustment mode, and the operation parameter includes a wind speed, an air outlet direction, a temperature value and a humidity adjustment duration.

[0013] The comfort requirement includes a humidity requirement, a temperature requirement, a wind speed and direction requirement and an air quality requirement.

[0014] Further, the operation mode further includes a sleep mode and an energy saving mode.

[0015] If the operation mode of the historical use data corresponding to the time period in which the current time is located is the sleep mode, it is determined whether at least one user in the air-conditioned room is in an active state, and if so, the air conditioner starts the energy saving mode until no user in the air-conditioned room is in an active state in a sixth time interval, and the air conditioner operates in the sleep mode.

[0016] If no user in the air-conditioned room is in an active state, the air conditioner operates in the sleep mode.

[0017] Further, in step S2, it is determined whether the historical use data can solve the air quality requirement according to the environmental information in the air-conditioned room and the time period in which the current time is located, including:

[0018] If the air quality index in the air-conditioned room is higher than a preset air quality index standard value, and if the historical use data corresponding to the time period in which the current time is located does not start the ventilation mode, the temperature adjustment mode or the humidity adjustment mode is closed and the ventilation mode is started in a first time interval, and the ventilation mode is closed when the air quality index is not higher than the preset air quality index standard value.

[0019] If the time period in which the current time is located is a lunch period or a dinner period, and if the historical use data corresponding to the time period in which the current time is located does not start the ventilation mode, the ventilation mode is started in a second time interval and the temperature adjustment mode or the humidity adjustment mode is closed in the lunch period or the dinner period, and then the temperature adjustment mode or the humidity adjustment mode is started and the ventilation mode is closed in a third time interval.

[0020] The third time interval is greater than the second time interval.

[0021] Further, in step S2, it is determined whether the historical use data can solve the humidity requirement according to the environmental information in the air-conditioned room, including the steps of:

[0022] If the current season is spring, it is determined whether the air humidity value in the air-conditioned room is higher than the upper limit value of the normal humidity range, if yes, it is determined whether the humidity adjustment mode is started to reduce the humidity in the historical use data corresponding to the time period in which the current time is located, if yes, step A is executed, if no, step B is executed;

[0023] A: it is determined whether the first humidity adjustment duration can reduce the air humidity value in the air-conditioned room to the normal humidity range, if yes, the air humidity is adjusted according to the historical use data, if no, the first humidity adjustment duration is extended until the air humidity value in the air-conditioned room is reduced to the normal humidity range;

[0024] B: the humidity adjustment mode is started, and the second humidity adjustment duration is set to reduce the air humidity value in the air-conditioned room to the normal humidity range;

[0025] If the current season is winter, it is determined whether the air humidity value in the air-conditioned room is lower than the upper limit value of the normal humidity range, if yes, it is determined whether the humidity adjustment mode is started to increase the humidity in the historical use data corresponding to the time period in which the current time is located, if yes, step C is executed, if no, step D is executed;

[0026] C: it is determined whether the third humidity adjustment duration can increase the air humidity value in the air-conditioned room to the normal humidity range, if yes, the air humidity is adjusted according to the historical use data, if no, the third humidity adjustment duration is extended until the air humidity value in the air-conditioned room is increased to the normal humidity range;

[0027] D: the humidity adjustment mode is started, and the fourth humidity adjustment duration is set to increase the air humidity value in the air-conditioned room to the normal humidity range.

[0028] Further, in step S2, it is determined whether the historical use data can solve the air speed and direction demand according to the number of users in the air-conditioned room, including steps:

[0029] When the number of users is 1:

[0030] The air conditioner uses the air speed and direction in the historical use data to blow air;

[0031] When the number of users is greater than or equal to 2:

[0032] The corresponding air speed and direction are obtained from the historical use data of different users, and the air direction is changed every fifth time interval to meet the air direction demand of different users, and the air speed is uniformly reduced or increased when the air direction changes to meet the air speed demand of the next user;

[0033] Wherein, the air direction of the air conditioner changes along the space connecting line of adjacent users at a uniform speed.

[0034] Preferably, the operating parameters also include the brightness value of the air-conditioning light, and the comfort requirements also include the light brightness requirements;

[0035] When the number of users is 1:

[0036] The air conditioner uses the light brightness from the historical usage data for display operation;

[0037] When the number of users is greater than or equal to 2:

[0038] The brightness values ​​of the corresponding lights are obtained from the historical usage data of different users. The air conditioner randomly assigns light brightness weights to different users. The adjusted light brightness value of the air conditioner is calculated based on the light brightness weights and light brightness values. The air conditioner uses the adjusted light brightness value for display, satisfying the relationship:

[0039]

[0040] Where n represents the number of users in the air-conditioned room, W i represents the light brightness weight of the i-th user, L i represents the light brightness value of the i-th user, and L represents the adjusted light brightness value of the air conditioner.

[0041] Preferably, it also includes:

[0042] Get current season information;

[0043] Obtain seasonal historical usage data corresponding to the current season and time period from each user's historical usage data, and generate a comfortable temperature range for each user in the current season based on the minimum temperature value and the maximum temperature value in the seasonal historical usage data;

[0044] When the comfortable temperature ranges of all users have a common temperature interval, the operating temperature of the air conditioner is set to the center value of the common temperature interval;

[0045] When the comfort temperature ranges of each user do not have a common temperature interval, if the current time falls in the morning and evening, the operating temperature of the air conditioner is set to the maximum value among the lower limits of all comfort temperature ranges; if the current time falls in the afternoon, the operating temperature of the air conditioner is set to the minimum value among the upper limits of all comfort temperature ranges;

[0046] When the comfort temperature ranges of some users have a common temperature interval, while the comfort temperature ranges of the remaining users do not have a common temperature interval, the upper limit or lower limit of the common temperature interval is selected as the operating temperature of the air conditioner.

[0047] Furthermore, after step S3 is executed, if the user actively updates the operating mode and operating parameters of the air conditioner, the air conditioner operates according to the latest operating mode and operating parameters, and the current operating mode, operating parameters, and the time period of the current time are stored as a new historical usage data;

[0048] Or if the user runs the air conditioner using historical usage data for a fourth time interval, the current operating mode, operating parameters, and the time period in which the current time falls are stored as a new piece of historical usage data.

[0049] One of the above technical solutions has the following advantages or beneficial effects:

[0050] By capturing historical user usage data, personalized adjustments can be made based on each user's preferences, enhancing user comfort. By monitoring the current number of users and environmental information, dynamic judgment can be made on whether everyone's comfort needs are being met. Relying on historical data for decision-making avoids errors caused by human error. Precise adjustments can be made based on missing comfort needs, preventing a poor experience in certain areas from reducing user satisfaction. Appropriate operating modes and parameter settings can reduce air conditioning load, thereby reducing equipment wear and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are merely embodiments of the present invention.

[0052] Figure 1 4 is a flow chart of an air conditioning comfort control method based on historical habits provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0053] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0054] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0055] With technological advancements and improved living standards, air conditioners have become an indispensable appliance in modern homes and offices. Traditional air conditioner control often relies on users manually setting parameters such as temperature, air speed, and direction. This method is not only cumbersome but also fails to meet the personalized comfort needs of different users at different times and in different environments.

[0056] Although there are some smart air-conditioning products on the market that can automatically adjust the operating status of the air conditioner by learning the user's usage habits, most of these products only consider the usage habits of a single user or in a fixed scenario, and do not take into account shared spaces with multiple people and complex and changing environmental factors.

[0057] Therefore, the present invention proposes an air conditioning comfort control method based on historical habits, such as Figure 1 As shown, the steps include:

[0058] S1: Obtaining corresponding historical usage data of the air conditioner according to user permissions, wherein the historical usage data includes the operating mode, operating parameters, and corresponding time period of the air conditioner;

[0059] Modern smart homes typically perform user identification and permission management. Different users may have different permission levels, such as family members or visitors. The air conditioner first verifies the user's legitimacy through identity verification (such as password, fingerprint, facial recognition, etc.). Once the user is identified, the air conditioner accesses relevant historical usage data. This historical usage data can be stored in a cloud database or local storage within the air conditioner. It contains information on multiple dimensions, such as past temperature settings, fan speeds, operating modes (such as cooling, heating), and time periods of use. This is achieved by recording user operations and monitoring each air conditioner action through sensors and air conditioner logs. Historical usage data reflects the user's personalized preferences and is the basis for understanding user needs. For example, if a user typically uses cooling mode at night and sets the air conditioner to 22°C, this information provides strong support for the development of subsequent control strategies.

[0060] S2: Determine whether the historical usage data can meet all comfort requirements based on the number of users in the air-conditioned room, environmental information, and / or the time period of the current time. If so, the air conditioner is operated according to the corresponding historical usage data within the current time period. If not, proceed to step S3.

[0061] The air conditioner performs real-time analysis based on the current number of users in the room, environmental information (such as indoor temperature and humidity, air quality, noise level, etc.) and the time period of the current time. For example, there may be three users in a room, and their comfort needs may vary due to different personal body sensations. In this step, the air conditioner compares the historical usage data with the current actual environmental conditions to determine whether the comfort needs of all users can be met. If there is only one user present and his / her historical preferences are consistent with the current environment, the air conditioner will consider that the needs can be met. If there is a deviation between the historical data and the environmental factors (such as a sudden increase in outdoor temperature or multiple users have different temperature requirements), it is determined that the current historical usage pattern cannot meet the needs of all users, so it is decided to jump to step S3 for appropriate adjustments.

[0062] S3: Control the on / off of the air conditioning operation mode and adjust the operation parameters within the corresponding time period according to the missing comfort needs.

[0063] If it determines that historical data is insufficient to meet user needs, the air conditioner will identify specific missing points. For example, if one user prefers a temperature of 27°C and another wants a temperature of 24°C, the air conditioner will need to make an appropriate compromise. The air conditioner adjusts its operating mode and parameters based on the identified missing needs. Controlling the on and off of the air conditioner operating mode means deciding whether to activate a certain mode of the air conditioner based on real-time data. For example, if the current indoor temperature in the room does not meet the current user's needs, the air conditioner will automatically enable the temperature adjustment mode according to the set program and set the specific cooling temperature. This step should also include a dynamic feedback mechanism, that is, constantly monitoring the environment and user feedback. For example, after running for a period of time, check again to see if the indoor temperature and humidity have reached the preset comfort standards. If not, adjust the settings again.

[0064] By capturing historical user usage data, this solution can make personalized adjustments based on each user's preferences, enhancing user comfort. By monitoring the current number of users and environmental information, it can dynamically determine whether everyone's comfort needs are being met. Relying on historical data for decision-making avoids errors caused by human error. Precise adjustments can be made based on missing comfort needs, preventing a poor experience in certain areas from reducing user satisfaction. Appropriate operating modes and parameter settings can reduce air conditioning load, thereby reducing equipment wear and extending its service life.

[0065] Preferably, if the corresponding air conditioner historical usage data cannot be obtained in step S1, the historical usage data of other users are counted to find the historical usage data with the most usage times in the time period of the current time;

[0066] If the statistics of the historical usage data of other users are 0 or the usage times of different historical usage data are the same, the air conditioner operates according to the preset default operation mode and default operation parameters.

[0067] Specifically, the air conditioner will first query the user's historical usage records, including the user's setting choices in different time periods, such as the set temperature, wind speed, operating mode, etc. The air conditioner is equipped with a device that can synchronize historical settings through the Internet. If the user's historical data cannot be obtained, the air conditioner will instead access the data generated by other users on the same air conditioning device. Once the data of other users is collected, the air conditioner will count the frequency of various usage settings in the current time period. Commonly used settings will be marked as "historical usage data with the most usage" for priority selection. If the statistical result is 0 or there is no significant difference in usage, the air conditioner will start a set of preset default parameters. The default operating mode and default parameters of the air conditioner change according to different air conditioners. The default operating mode and default parameters are the air conditioning operating status acceptable to most people, aiming to provide a "comfortable" baseline setting for most users (for example, in summer cooling mode, it is set to 24°C and the wind speed is medium).

[0068] Preferably, the operating modes include: temperature adjustment mode, ventilation mode and humidity adjustment mode, and the operating parameters include: wind speed, air outlet direction, temperature value and humidity adjustment time;

[0069] The comfort requirements include: humidity requirements, temperature requirements, wind speed and direction requirements, and air quality requirements.

[0070] Specifically, in hot summer or cold winter, the temperature adjustment mode can effectively maintain a comfortable indoor temperature through cooling or heating, preventing discomfort caused by extreme temperatures, and intelligent temperature control can reduce unnecessary energy consumption and lower electricity bills. In a closed environment, carbon dioxide and other harmful gases will gradually accumulate. The ventilation mode improves indoor air quality by introducing fresh air. Regular ventilation can effectively eliminate indoor odors and pollutants and keep the indoor air fresh. The humidity adjustment mode can prevent the indoor environment from being too humid (causing mold growth) or too dry (causing dry skin and respiratory discomfort), maintaining a healthy humidity level, especially when the seasons change, appropriate humidity can improve living comfort.

[0071] In terms of wind speed adjustment, high wind speed can improve the user's comfort in hot weather and promote rapid air circulation; low wind speed provides slow air flow, enhances comfort, and is suitable for nighttime or long periods of stillness. The adjustment of the air outlet direction can meet the user's usage habits. In most air conditioners, users can only control the switch of the dehumidification or humidification operation, but cannot control the intensity of the dehumidification or humidification operation. Therefore, adjusting the humidity adjustment time can determine the effect of the dehumidification or humidification operation. The design of each operating mode and parameter adjustment is aimed at solving different indoor environmental problems, and by meeting comfort needs, ensure that users get the best experience and health protection when using air conditioning.

[0072] In another embodiment, the operating mode further includes a sleep mode and a power saving mode;

[0073] If the operating mode of the historical usage data corresponding to the time period of the current time is sleep mode, determining whether there is an active user in the air-conditioned room, and if at least one user is active, turning on the air conditioner in energy-saving mode until no user is active within a sixth time interval, and the air conditioner operates in sleep mode;

[0074] If there is no active user, the air conditioner operates in sleep mode.

[0075] Specifically, the air conditioner determines the current operating mode according to the time period and historical usage data, such as the temperature setting and operating mode during the noon period. If the historical usage data shows that the user's operating mode during the time period in which the current time falls is the sleep mode (indicating that the user is likely to sleep or is close to the user's sleep time), the air conditioner uses sensor technology to monitor the user's activity in the room in real time. Through the detection of user activity, the air conditioner can determine whether to switch to the energy-saving mode. If user activity is still detected within the sixth time interval, the air conditioner will continue to maintain the energy-saving mode; once no user activity is detected within the time period, the air conditioner will automatically switch back to the sleep mode. The switching of the operating mode is based on the user's activity status and time period setting. When the user's activity status is confirmed, the air conditioner will switch between the "sleep mode" and the "energy-saving mode" to optimize energy efficiency and user experience. The sleep mode is a specially designed operating mode designed to provide optimal comfort to help users fall asleep and stay asleep better at night. By gradually reducing or adjusting the temperature, the user will not feel too hot or too cold during sleep, thereby improving sleep quality. The energy-saving mode is an operating mode designed to reduce energy consumption, which usually adjusts the temperature setting and wind speed to reduce power consumption. Under the premise of maintaining a certain level of comfort, it reduces the use of electric energy to achieve the effect of energy saving. The sleep mode focuses more on user comfort and sleep quality, while the energy-saving mode focuses on reducing energy consumption and electricity bills. When using, choose the appropriate mode according to different needs to improve the efficiency and comfort of the air conditioner.

[0076] Further, in step S2, it is determined whether the historical usage data can meet the air quality demand according to the environmental information in the air-conditioned room and the time period in which the current time falls, including:

[0077] If the air quality index in the air-conditioned room is higher than the preset air quality index standard value, and the historical usage data corresponding to the time period in which the current time falls does not open the ventilation mode, then in the first time interval, the temperature regulation mode or the humidity regulation mode is closed and the ventilation mode is opened. When the air quality index is not higher than the preset air quality index standard value, the ventilation mode is closed.

[0078] If the time period in which the current time falls is the lunch period or the dinner period, and the historical usage data corresponding to the time period in which the current time falls does not open the ventilation mode, then in the second time interval during the lunch period or the dinner period, the ventilation mode is opened and the temperature regulation mode or the humidity regulation mode is closed. Subsequently, in the third time interval, the temperature regulation mode or the humidity regulation mode is opened and the ventilation mode is closed.

[0079] Among them, the third time interval is greater than the second time interval.

[0080] Specifically, the air conditioner monitors the air quality index (AQI) in the room in real time through a built-in sensor. When the air quality index (AQI) in the room is higher than the preset air quality index standard value, it means that the air quality in the air-conditioned room is not up to standard. First, determine whether the ventilation mode is turned on in the historical usage data corresponding to the time period of the current time. If the AQI exceeds the standard value and the ventilation mode is not turned on in the historical data, the air conditioner will prioritize turning off the temperature adjustment mode or the humidity adjustment mode to start the ventilation mode to introduce fresh air. When the air quality in the air-conditioned room is up to standard, the indoor temperature may rise or fall due to the ventilation mode exchanging air with the external environment. The ventilation mode will be turned off and switched back to the temperature adjustment mode or the humidity adjustment mode.

[0081] In addition, when users eat during lunch or dinner time, the smell of food will change the smell in the air-conditioned room. This feeling is particularly strong when users enter and exit the air-conditioned room. Therefore, for specific time periods (such as lunch and dinner time), since turning on the ventilation mode will cause the loss of cooling or heating in the room, in order not to reduce the user experience, the ventilation mode is turned on and the temperature adjustment mode or the humidity adjustment mode is turned off within a second time interval (such as 5 minutes). The temperature adjustment mode or the humidity adjustment mode is turned on and the ventilation mode is turned off within a third time interval (after 10 minutes). That is, in 15 minutes, the temperature adjustment mode or the humidity adjustment mode is turned on for 10 minutes and the ventilation mode is turned off, and the temperature adjustment mode or the humidity adjustment mode is turned off for 5 minutes and the ventilation mode is turned on. The third time interval is greater than the second time interval because the air quality in the air-conditioned room is qualified, but the smell of food will affect the user experience. Therefore, it is necessary to prioritize maintaining the heating or cooling in the air-conditioned room and expel the smell of food in the air-conditioned room while maintaining the user experience.

[0082] Furthermore, step S2 includes determining whether the historical usage data can meet the humidity requirement based on the environmental information in the air-conditioned room, including the steps of:

[0083] If the current season is spring, determine whether the air humidity value in the air-conditioned room is higher than the upper limit of the normal humidity range. If so, determine whether the humidity adjustment mode is turned on to reduce the humidity in the historical usage data corresponding to the time period of the current time. If so, execute step A; if not, execute step B.

[0084] A: Determine whether the first humidity adjustment time can reduce the air humidity value in the air-conditioned room to a normal humidity range. If so, adjust the air humidity according to the historical usage data. If not, extend the first humidity adjustment time until the air humidity value in the air-conditioned room is reduced to a normal humidity range.

[0085] B: Turn on the humidity adjustment mode and set the second humidity adjustment time to reduce the air humidity in the air-conditioned room to a normal humidity range;

[0086] If the current season is winter, determine whether the air humidity value in the air-conditioned room is lower than the upper limit of the normal humidity range. If so, determine whether the humidity adjustment mode is turned on to increase the humidity in the historical usage data corresponding to the time period of the current time. If so, execute step C; if not, execute step D.

[0087] C: Determine whether the third humidity adjustment time can increase the air humidity value in the air-conditioned room to within the normal humidity range. If so, adjust the air humidity according to the historical usage data. If not, extend the third humidity adjustment time until the air humidity value in the air-conditioned room increases to within the normal humidity range.

[0088] D: Turn on the humidity adjustment mode and set the fourth humidity adjustment time to increase the air humidity value in the air-conditioned room to within the normal humidity range.

[0089] When humidity rises above 60%, people feel unbearably hot and stuffy because it hinders the body's cooling mechanism, making them uncomfortable even when the temperature is not high. When humidity rises further to above 80%, heat dissipation becomes even more difficult, leading to symptoms such as elevated body temperature, increased heart rate, irritability, fatigue, and dizziness. High humidity also breeds dust mites and mold, increasing the allergen load for allergy sufferers. High humidity also accelerates bacterial growth and reproduction, leading to food and water contamination. Low humidity accelerates the evaporation of moisture from the skin, causing dryness, cracking, and even inflammation. Excessively low humidity can irritate the nasal mucosa, respiratory tract, and eyes, leading to symptoms such as a dry cough, scanty sputum, and thirst.

[0090] Seasonal changes directly affect the moisture content in the air and the human perception of humidity. The air's temperature and humidity characteristics vary across seasons. For example, spring is typically more humid, while winter is relatively dry. For example, in southern China, during the return of the southerly winds in spring, indoor humidity increases significantly. Air conditioners use digital humidity sensors (such as capacitive or impedance sensors) to measure indoor air humidity in real time. After determining the current humidity value relative to the normal humidity range, the air conditioner selects the most appropriate humidity adjustment strategy based on specific conditions (season, humidity value, and historical data). If the air conditioner determines that the humidity adjustment mode and duration from historical usage data can reduce the humidity in the air-conditioned room to within the normal humidity range, it will perform dehumidification based on the humidity adjustment mode and duration from the historical usage data. If the air conditioner determines that this is not possible, it will extend the humidity adjustment duration to bring the current humidity within the normal range. Similarly, in winter, if the humidity value in the air-conditioned room falls below the upper limit of the normal humidity range, the humidity adjustment duration will be adjusted until the humidity value returns to the normal range.

[0091] Furthermore, step S2 includes determining whether the historical usage data can meet the wind speed and direction requirements based on the number of users in the air-conditioned room, including the following steps:

[0092] When the number of users is 1:

[0093] The air conditioner uses the wind speed and direction in the historical usage data to perform air output operations;

[0094] When the number of users is greater than or equal to 2:

[0095] The corresponding wind speed and airflow direction are obtained from the historical usage data of different users. The air conditioner changes the airflow direction every fifth time interval to meet the airflow direction requirements of different users. When the airflow direction changes, the wind speed is uniformly reduced or increased to meet the wind speed requirements of the next user.

[0096] Among them, the air outlet direction of the air conditioner is changed to change uniformly along the spatial connection line of adjacent users.

[0097] Specifically, step S2 works by monitoring the number of users in the air-conditioned room in real time and, in combination with historical usage data, intelligently adjusting the air conditioner's wind speed and air direction. Specifically, when there's only one user in the room, the air conditioner directly uses that user's past wind speed and air direction data to quickly and accurately meet their needs, ensuring optimal comfort. For example, if a user's historical data indicates a preference for medium wind speed and upward airflow, the air conditioner will operate according to these settings. However, when there are two or more users in the room, the air conditioner analyzes each user's historical usage data to determine their respective wind speed and air direction preferences, adjusting the air direction at regular intervals (e.g., every minute) to rotate between users. During this process, the air conditioner also smoothly increases or decreases the wind speed based on the change in air direction to meet the needs of the next user, ensuring a smooth transition of airflow. For example, if the first user prefers forward airflow and the second user prefers rightward airflow, the air conditioner will uniformly change the air direction along the spatial line connecting the users with each adjustment, optimizing air flow and improving air distribution and comfort throughout the room. This intelligent adjustment not only improves the adaptability and energy efficiency of air conditioning, but also effectively solves the problems of user discomfort and temperature differences within the space caused by traditional air conditioning settings.

[0098] Preferably, the operating parameters also include the brightness value of the air-conditioning light, and the comfort requirements also include the light brightness requirements;

[0099] When the number of users is 1:

[0100] The air conditioner uses the light brightness from the historical usage data for display operation;

[0101] When the number of users is greater than or equal to 2:

[0102] The brightness values ​​of the corresponding lights are obtained from the historical usage data of different users. The air conditioner randomly assigns light brightness weights to different users. The adjusted light brightness value of the air conditioner is calculated based on the light brightness weights and light brightness values. The air conditioner uses the adjusted light brightness value for display, satisfying the relationship:

[0103]

[0104] Where n represents the number of users in the air-conditioned room, W i represents the light brightness weight of the i-th user, L i represents the light brightness value of the i-th user, and L represents the adjusted light brightness value of the air conditioner.

[0105] Usually the temperature on the air conditioner is displayed as a switchable light. The temperature display light can help users easily adjust the air conditioner settings at night or in low-light environments. The display content can be clearly seen without strong lighting, which improves the convenience of operation. However, lights with too high brightness will affect users. By collecting users' historical usage data, each user's preference for light brightness is determined. When there is a single user in the room, the air conditioner directly extracts the preferred light brightness value from the user's historical data for adjustment. For example, the brightness most frequently selected by the user in the past is 300 lumens, and the air conditioner will be set to 300 lumens. If there are multiple users in the room, such as two users A and B, the historical light brightness value of user A is 250 lumens, and that of user B is 350 lumens. In order to adjust the light brightness, the air conditioner will randomly assign weights to each user, for example, A's weight is 0.4 and B's weight is 0.6. According to the formula Adjusted light brightness value Therefore, the air conditioner will set the light to 310 lumens to balance the preferences of the two users, thereby improving overall user comfort. In this way, the air conditioner can not only achieve personalized lighting adjustment, but also solve the user discomfort caused by fixed brightness settings, and improve user satisfaction with the living and working environment.

[0106] Preferably, it also includes:

[0107] Get current season information;

[0108] Obtain seasonal historical usage data corresponding to the current season and time period from each user's historical usage data, and generate a comfortable temperature range for each user in the current season based on the minimum temperature value and the maximum temperature value in the seasonal historical usage data;

[0109] When the comfortable temperature ranges of all users have a common temperature interval, the operating temperature of the air conditioner is set to the center value of the common temperature interval;

[0110] When the comfort temperature ranges of each user do not have a common temperature interval, if the current time falls in the morning and evening, the operating temperature of the air conditioner is set to the maximum value among the lower limits of all comfort temperature ranges; if the current time falls in the afternoon, the operating temperature of the air conditioner is set to the minimum value among the upper limits of all comfort temperature ranges;

[0111] When the comfort temperature ranges of some users have a common temperature interval, while the comfort temperature ranges of the remaining users do not have a common temperature interval, the upper limit or lower limit of the common temperature interval is selected as the operating temperature of the air conditioner.

[0112] Specifically, the principle of obtaining the current season information is based on meteorological data. The current date is determined through the air conditioner's internal clock or network service to identify whether it is spring, summer, autumn or winter. Subsequently, the air conditioner will access each user's historical usage data, which includes past air conditioner setting records (such as temperature, time period, etc.) to analyze the user's preferences in different seasons. For example, suppose user A's historical data shows that in the summer, the minimum temperature is set to 22°C and the maximum temperature is set to 26°C, while user B's minimum temperature in the same season is 23°C and the maximum temperature is 28°C. Then, in this season, user A's comfortable temperature range is 22°C to 26°C, and user B's range is 23°C to 28°C. Combining this information, the air conditioner will next look for a common interval of these temperature ranges. If it exists (such as a common range of 23°C to 26°C), the air conditioner will be set to the center value of the common interval (24.5°C);

[0113] Assume that the comfort temperature ranges of users D, E, and F in their historical summer usage data are 21°C to 22°C, 23°C to 24°C, and 25°C to 26°C, respectively. If the current time is morning or evening, there is no common temperature interval between their comfort temperature ranges, and the lower limits of all comfort temperature ranges are 21°C, 23°C, and 25°C, respectively. In this case, the operating temperature of the air conditioner is set to the maximum value, 25°C. If the current time is afternoon, there is no common temperature interval between their comfort temperature ranges, and the upper limits of all comfort temperature ranges are 22°C, 24°C, and 26°C, respectively. In this case, the operating temperature of the air conditioner is set to the minimum value, 22°C. Although the comfort temperature ranges of users D, E, and F are different, the set temperature (25°C or 22°C) can meet the needs of each user to a certain extent. The outdoor temperature is relatively low in the morning and evening, so a higher temperature is set. The outdoor temperature is relatively high in the afternoon, so a lower temperature is set to improve the user experience.

[0114] Assume that the comfort temperature ranges of users D, E, and F in their historical summer usage data are 21°C to 23°C, 22°C to 24°C, and 25°C to 26°C, respectively. Users D and E share a common comfort temperature range of 22°C-23°C, and user F's comfort temperature range is 25°C to 26°C (greater than 22°C-23°C). Therefore, the air conditioner's operating temperature is set to the upper limit of 23°C. If user F's comfort temperature range is 18°C-19°C, the air conditioner's operating temperature is set to the lower limit of 22°C. A common temperature range is formed between users D and E, and the air conditioner prioritizes meeting the requirements of the majority. Then, based on the comfort temperature ranges of users not in the common temperature range and the values ​​of the common temperature range, the air conditioner's operating temperature is set to the upper or lower limit of the common temperature range, so as to maintain the user experience of other users who are not in the comfort temperature range as much as possible.

[0115] Preferably, after step S3 is performed, if the user actively updates the operation mode and operation parameters of the air conditioner, the air conditioner operates according to the latest operation mode and operation parameters, and stores the current operation mode, operation parameters, and time period in which the current time is located as a new piece of historical use data.

[0116] Or if the user stores the current operation mode, operation parameters, and time period in which the current time is located as a new piece of historical use data after the air conditioner uses the historical use data for a fourth time interval.

[0117] Specifically, if the user actively inputs the operation mode and parameters, the air conditioner adds a piece of historical use data to the storage space or the cloud database, with the user-modified operation mode and operation parameters, and the time period in which the current time is located. Or the air conditioner recommends the operation mode and operation parameters to the user, and the user does not actively modify them after using for a certain time. The air conditioner considers that the recommended operation mode and operation parameters meet the user's needs in the current time period, and also adds a piece of historical use data. By recording the active input and preferences of the user, the air conditioner can better meet the personalized needs of the user. With the passage of time, the air conditioner will accumulate more data, thereby providing more accurate recommendations.
