Description

Technical Field

[0001] The 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 the advancement of technology and the improvement of people's living standards, air conditioners have become an indispensable electrical appliance in modern homes and offices. The control method of traditional air conditioners often relies on users to manually set parameters such as temperature, wind speed, and wind direction. This method is not only cumbersome to operate, but also difficult 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 view of 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 conditioner 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, so as 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: Obtain corresponding historical usage data of the air conditioner according to the user's authority, wherein the historical usage data includes an operation mode, operation parameters and a corresponding time period of the air conditioner;

[0008] S2: judging whether the historical usage data can meet all comfort requirements according to 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 executed in the current time period according to the corresponding historical usage data, if not, executing 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 requirements.

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

[0011] If the statistics of the historical usage data of other users is 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.

[0012] Preferably, the operation modes include: temperature adjustment mode, ventilation mode and humidity adjustment mode, and the operation parameters include: wind speed, air outlet direction, temperature value and humidity adjustment time;

[0013] The comfort requirements include: humidity requirements, temperature requirements, wind speed and direction requirements, and air quality requirements.

[0014] Furthermore, the operating mode also includes a sleep mode and an energy-saving mode;

[0015] If the operation mode of the historical usage data corresponding to the time period of the current time is the sleep mode, determine whether there is an active user in the air-conditioned room, and if at least one user is active, turn on the energy-saving mode of the air conditioner until no user is active within a sixth time interval, and the air conditioner runs in the sleep mode;

[0016] If there is no user activity, the air conditioner operates in sleep mode.

[0017] Furthermore, step S2 includes judging whether the historical usage data can meet the air quality requirements according to the environmental information in the air-conditioned room and the time period of the current time, including:

[0018] If the air quality index in the air-conditioned room is higher than the preset air quality index standard value, and if the historical usage data corresponding to the time period of the current time does not turn on the ventilation mode, then turn off the temperature adjustment mode or the humidity adjustment mode and turn on the ventilation mode within the first time interval, and turn off the ventilation mode when the air quality index is not higher than the preset air quality index standard value;

[0019] If the time period of the current time is the lunch period or the dinner period, and if the ventilation mode is not turned on in the historical usage data corresponding to the time period of the current time, then the ventilation mode is turned on in the second time interval during the lunch period or the dinner period, and the temperature adjustment mode or the humidity adjustment mode is turned off, and then the temperature adjustment mode or the humidity adjustment mode is turned on in the third time interval, and the ventilation mode is turned off;

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

[0021] Further, step S2 includes judging whether the historical usage data can meet the humidity requirement according to the environmental information in the air-conditioned room, including the steps of:

[0022] 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 in the historical usage data corresponding to the time period of the current time to reduce the humidity. If so, execute step A. If not, execute step B.

[0023] 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;

[0024] B: Turn on the humidity adjustment mode and set the second humidity adjustment time to reduce the air humidity value in the air-conditioned room to a normal humidity range;

[0025] 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 in the historical usage data corresponding to the time period of the current time to increase the humidity. If so, execute step C. If not, execute step D.

[0026] C: Determine whether the third humidity adjustment time can make the air humidity value in the air-conditioned room rise to 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 rises to the normal humidity range;

[0027] D: Turn on the humidity adjustment mode and set the fourth humidity adjustment time to raise the air humidity value in the air-conditioned room to within the normal humidity range.

[0028] Further, step S2 includes judging whether the historical usage data can meet the wind speed and direction requirements according to the number of users in the air-conditioned room, including the steps of:

[0029] When the number of users is 1:

[0030] The air conditioner uses the wind speed and wind direction in the historical usage data to perform air outlet operation;

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

[0032] The corresponding wind speed and air outlet direction are obtained from the historical usage data of different users. The air conditioner changes the air outlet direction every fifth time interval to meet the air outlet direction requirements of different users. When the air outlet direction changes, the wind speed is uniformly reduced or increased to meet the wind speed requirement of the next user.

[0033] Among them, the air outlet direction of the air conditioner is changed to change uniformly along the spatial connection line of adjacent users.

[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 air conditioner light brightness value is calculated based on the light brightness weight and the light brightness value. The air conditioner uses the adjusted air conditioner 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 light brightness value of the air conditioner after adjustment.

[0041] Preferably, it also includes:

[0042] Get current season information;

[0043] Obtaining seasonal historical usage data corresponding to the current season and time period from the historical usage data of each user, and generating 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 among all users have a common temperature interval, the operating temperature of the air conditioner is set to the central value of the common temperature interval;

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

[0046] When the comfort temperature ranges of some users have a common temperature interval, and the comfort temperature ranges of the remaining users do not have a common temperature interval, the upper limit value or the lower limit value 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 operation mode and operation parameters of the air conditioner, the air conditioner operates according to the latest operation mode and operation parameters, and the current operation mode, operation 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 for a fourth time interval using the historical usage data, the current operation mode, operation parameters, and the time period in which the current time is located 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 obtaining the user's historical usage data, it is possible to make personalized adjustments based on each user's personal preferences to improve the user's comfort. By monitoring the current number of users and environmental information, it is possible to dynamically determine whether the comfort needs of all people are met, and rely on historical data to make decisions, avoiding errors in human settings. Make precise adjustments based on missing comfort needs to avoid poor experience in certain aspects that lead to reduced user satisfaction. Reasonable operating modes and parameter settings can reduce the load of the air conditioner, thereby reducing equipment wear and tear and increasing its service life.

Obviously, the drawings described below are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0052] Figure 1 It 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] 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.

[0054] 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.

[0055] With the advancement of technology and the improvement of people's living standards, air conditioners have become an indispensable electrical appliance in modern homes and offices. The control method of traditional air conditioners often relies on users to manually set parameters such as temperature, wind speed, and wind direction. This method is not only cumbersome to operate, but also difficult 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: Obtain corresponding historical usage data of the air conditioner according to the user's authority, wherein the historical usage data includes an operation mode, operation parameters and a corresponding time period of the air conditioner;

[0059] Modern smart homes usually identify users and manage their permissions. Different users may have different permission levels, such as family members or visitors. The air conditioner first confirms whether the user is legitimate through identity authentication (such as password, fingerprint, facial recognition, etc.). Once the user is identified, the air conditioner calls the relevant historical usage data. The historical usage data can be stored in a cloud database or local storage in the air conditioner, and contains information in multiple dimensions, such as past temperature settings, wind speed, operating mode (such as cooling, heating), and time period used. This is achieved by recording the user's operations and monitoring each air conditioning behavior 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 usually uses the cooling mode at night and sets the air conditioner to 22°C, this information provides strong support for the formulation of subsequent control strategies.

[0060] S2: judging whether the historical usage data can meet all comfort requirements according to 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 executed in the current time period according to the corresponding historical usage data, if not, executing 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 in which the current time is located. 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 match the current environment, the air conditioner will consider that the needs can be met. If there is a deviation between the historical data and 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 requirements.

[0063] When it is determined 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 the temperature to be 24°C, then the air conditioner needs to make a suitable compromise. The air conditioner adjusts the operating mode and parameters of the air conditioner based on the identified missing needs. Controlling the on and off of the air conditioner operating mode means deciding whether to start a certain mode of the air conditioner based on real-time data. For example, if the current indoor temperature in the room is not suitable for the current user, the air conditioner will automatically enable the temperature adjustment mode according to the set program and set the specific temperature for cooling. 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 whether the indoor temperature and humidity have reached the preset comfort standard. If not, adjust the settings again.

[0064] This solution can make personalized adjustments based on each user's personal preferences and improve user comfort by obtaining historical usage data. By monitoring the current number of users and environmental information, it can dynamically determine whether the comfort needs of all people are met, relying on historical data for decision-making, and avoiding errors in human settings. Accurate adjustments are made based on missing comfort needs to avoid poor experience in certain aspects that lead to reduced user satisfaction. Reasonable operating modes and parameter settings can reduce the load of the air conditioner, thereby reducing equipment wear and tear and increasing its service life.

[0065] Preferably, if the corresponding historical usage data of the air conditioner cannot be obtained in step S1, the historical usage data of other users are counted to find out 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 is 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 times" 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 that most people can accept, 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 operation modes include: temperature adjustment mode, ventilation mode and humidity adjustment mode, and the operation 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 to prevent discomfort caused by extreme temperatures, and intelligent temperature control can reduce unnecessary energy consumption and reduce 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), and maintain a healthy humidity level. Especially when the seasons change, appropriate humidity can improve living comfort.

[0071] In the adjustment of wind speed, 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-term static environments. 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 operation or humidification operation, but cannot control the intensity of the dehumidification operation or humidification operation. Therefore, adjusting the humidity adjustment time can determine the effect of the dehumidification operation or humidification operation. The design of each operating mode and parameter adjustment is to solve different indoor environmental problems, and to ensure that users get the best experience and health protection when using air conditioners by meeting comfort needs.

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

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

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

[0075] Specifically, the air conditioner will determine the current operating mode based on the time period and historical usage data, such as the temperature setting and operating mode for the noon period. If the operating mode used by the user in the time period of the current time in the historical usage data is the sleep mode (indicating that the user may be sleeping or close to the user's sleeping time at the current time), the air conditioner will use sensor technology to monitor the user's activities in the room in real time. By detecting the user's activities, the air conditioner can determine whether it needs to switch to the energy-saving mode. If user activities are still detected within the sixth time interval, the air conditioner will continue to maintain the energy-saving mode; once no user activities are detected within this 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 settings. When the status of the user's activity is confirmed, the air conditioner will switch between "sleep mode" and "energy-saving mode" to optimize energy efficiency and user experience. Sleep mode is a specially designed working mode that aims to provide optimal comfort to help users fall asleep and stay asleep better at night. By gradually lowering or adjusting the temperature, the user will not feel overheated or overcooled during sleep, thereby improving sleep quality. Energy saving mode is an operating mode designed to reduce energy consumption. It 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 electricity and achieves energy saving. Sleep mode pays more attention to the user's comfort and sleep quality, while energy saving mode focuses on reducing energy consumption and electricity bills. When using, choosing the appropriate mode according to different needs can improve the efficiency and comfort of air conditioning.

[0076] Furthermore, step S2 includes judging whether the historical usage data can meet the air quality requirements according to the environmental information in the air-conditioned room and the time period of the current time, including:

[0077] If the air quality index in the air-conditioned room is higher than the preset air quality index standard value, and if the historical usage data corresponding to the time period of the current time does not turn on the ventilation mode, then turn off the temperature adjustment mode or the humidity adjustment mode and turn on the ventilation mode within the first time interval, and turn off the ventilation mode when the air quality index is not higher than the preset air quality index standard value;

[0078] If the time period of the current time is the lunch period or the dinner period, and if the ventilation mode is not turned on in the historical usage data corresponding to the time period of the current time, then the ventilation mode is turned on in the second time interval during the lunch period or the dinner period, and the temperature adjustment mode or the humidity adjustment mode is turned off, and then the temperature adjustment mode or the humidity adjustment mode is turned on in the third time interval, and the ventilation mode is turned off;

[0079] 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 the 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 is turned off and switched back to the temperature adjustment mode or the humidity adjustment mode.

[0081] In addition, when users are eating 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 indoor cooling or heating, in order not to reduce the user experience, the ventilation mode is turned on within a second time interval (such as 5 minutes), and the temperature adjustment mode or the humidity adjustment mode is turned off. Within the third time interval (after 10 minutes), the temperature adjustment mode or the humidity adjustment mode is turned on, and the ventilation mode is turned off. 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, so 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] Further, step S2 includes judging whether the historical usage data can meet the humidity requirement according to 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 in the historical usage data corresponding to the time period of the current time to reduce the humidity. 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 value 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 in the historical usage data corresponding to the time period of the current time to increase the humidity. If so, execute step C. If not, execute step D.

[0087] C: Determine whether the third humidity adjustment time can make the air humidity value in the air-conditioned room rise to 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 rises to the normal humidity range;

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

[0089] When the air humidity is higher than 60%, the human body will feel hot and stuffy, because humidity hinders the body's cooling mechanism, and will feel uncomfortable even if the temperature is not high. When the humidity further rises to more than 80%, it is more difficult for the human body to dissipate heat, which can easily lead to symptoms such as increased body temperature, increased heart rate, irritability, fatigue, and dizziness. High humidity environments are prone to breeding dust mites and mold, increasing the allergen load of allergy patients. At the same time, high humidity will accelerate the growth and reproduction of bacteria, causing food and water pollution. Low humidity environments will accelerate the evaporation of skin moisture, causing dry and chapped skin, and even causing skin inflammation. Too low humidity will irritate the nasal mucosa, respiratory tract and eyes, and easily induce symptoms such as dry cough, little sputum, and thirst.

[0090] Seasonal changes directly affect the moisture content in the air and the human body's perception of humidity. The temperature and humidity characteristics of the air are different in different seasons. For example, spring is usually humid, while winter air is relatively dry. For example, in the spring in the south, the indoor humidity increases greatly when the south wind returns. The air conditioner uses a digital humidity sensor (such as capacitive, impedance, etc.) to measure the humidity of the indoor air in real time. After judging the relationship between the current humidity value and the normal humidity range, the air conditioner will select the most suitable humidity adjustment strategy according to the specific conditions (season, humidity value, historical data). The air conditioner determines that the humidity adjustment mode and humidity adjustment time in the historical usage data can reduce the humidity of the current air-conditioned room to the normal humidity range. The air conditioner performs dehumidification according to the humidity adjustment mode and humidity adjustment time in the historical usage data. If the air conditioner thinks it cannot, it needs to extend the humidity adjustment time to adjust the current humidity to the normal humidity range. If the current season is winter, then similarly, when the air humidity value in the air-conditioned room is lower than the upper limit of the normal humidity range, the humidity adjustment time is adjusted until the air humidity value in the air-conditioned room rises to the normal humidity range.

[0091] Further, step S2 includes judging whether the historical usage data can meet the wind speed and direction requirements according to the number of users in the air-conditioned room, including the steps of:

[0092] When the number of users is 1:

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

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

[0095] The corresponding wind speed and air outlet direction are obtained from the historical usage data of different users. The air conditioner changes the air outlet direction every fifth time interval to meet the air outlet direction requirements of different users. When the air outlet direction changes, the wind speed is uniformly reduced or increased to meet the wind speed requirement 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, the principle of step S2 is to adjust the wind speed and air outlet direction of the air conditioner in an intelligent way by monitoring the number of users in the air-conditioned room in real time and combining historical usage data. Specifically, when there is only one user in the room, the air conditioner will directly use the user's past wind speed and air outlet direction data to quickly and accurately meet its needs and ensure the best comfort. For example, if the user's historical data shows a preference for medium wind speed and upward air outlet, the air conditioner will work according to these settings. However, when there are two or more users in the room, the air conditioner will analyze the historical usage data of each user, obtain their respective wind speed and air outlet direction preferences, and adjust the air outlet direction every certain time interval (such as every minute) to rotate between different users. In this process, the air conditioner will also smoothly increase or decrease the wind speed according to the change of the air outlet direction to meet the requirements of the next user and ensure a smooth transition of the air flow. For example, if the first user prefers to outlet air forward and the second user prefers to outlet air to the right, the air conditioner will change the air outlet direction at a uniform speed along the spatial connection between the users at each adjustment, thereby optimizing the air flow and improving the uniformity and comfort of the air distribution in the entire 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 air conditioner light brightness value is calculated based on the light brightness weight and the light brightness value. The air conditioner uses the adjusted air conditioner 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 light brightness value of the air conditioner after adjustment.

[0105] Usually the temperature on the air conditioner is displayed with 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 can be 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 commonly 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, for example, there are 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 the overall comfort of use. 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 the satisfaction of the living and working environment.

[0106] Preferably, it also includes:

[0107] Get current season information;

[0108] Obtaining seasonal historical usage data corresponding to the current season and time period from the historical usage data of each user, and generating 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 among all users have a common temperature interval, the operating temperature of the air conditioner is set to the central value of the common temperature interval;

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

[0111] When the comfort temperature ranges of some users have a common temperature interval, and the comfort temperature ranges of the remaining users do not have a common temperature interval, the upper limit value or the lower limit value 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 internal clock of the air conditioner or the network service to identify whether it is spring, summer, autumn or winter. Subsequently, the air conditioner will access the historical usage data of each user, 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 the minimum temperature is set to 22°C and the maximum temperature is set to 26°C in the summer, while user B's minimum is 23°C and the maximum is 28°C in the same season. Then, in this season, the comfortable temperature range of user A is 22°C to 26°C, and the range of user B is 23°C to 28°C. Combined with this information, the air conditioner will next look for the common interval of these temperature ranges. If it exists (such as the common range is 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 usage data in summer 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 range between their comfort temperature ranges, and the lower limits of all comfort temperature ranges are 21°C, 23°C, and 25°C, respectively. Then, the operating temperature of the air conditioner is set to the maximum value therein, 25°C; if the current time is afternoon, there is no common temperature range between their comfort temperature ranges, and the upper limits of all comfort temperature ranges are 22°C, 24°C, and 26°C, respectively. Then, the operating temperature of the air conditioner is set to the minimum value therein, 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 low in the morning and evening, so a higher temperature is set. The outdoor temperature is 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 usage data in summer are 21°C to 23°C, 22°C to 24°C, and 25°C to 26°C, respectively. Users D and E have a common comfort temperature range of 22°C-23°C, and the comfort temperature range of user F is 25°C to 26°C and greater than 22°C-23°C. Therefore, the operating temperature of the air conditioner is set to the upper limit of 23°C. If the comfort temperature range of user F is 18°C-19°C, the operating temperature of the air conditioner is set to the lower limit of 22°C. A common temperature range is formed between users D and E, and the air conditioner gives priority to meeting the requirements of the majority of people. Then, based on the comfort temperature range that is not in the common temperature range and the value of the common temperature range, it is decided to set the operating temperature of the air conditioner to the upper limit or lower limit of the common temperature range, so as to maintain the experience of other users who are not in the comfort temperature range as much as possible.

[0115] Preferably, 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 piece of historical usage data;

[0116] Or if the user runs the air conditioner for a fourth time interval using the historical usage data, the current operation mode, operation parameters, and the time period in which the current time is located are stored as a new piece of historical usage data.

[0117] Specifically, if the user actively inputs the operation mode and parameters, the air conditioner will add the user's modified operation mode and operation parameters, plus the time period information of the current time, to the storage space or cloud database, or if the air conditioner recommends an operation mode and operation parameters for the user, and the user does not actively modify them after using it for a certain period of time, the air conditioner will consider that the recommended operation mode and operation parameters meet the user's needs in the current time period, and will also add a new historical usage data for it. By recording the user's active input and preferences, the air conditioner can better meet the user's personalized needs. Over time, the air conditioner will accumulate more data and provide more accurate recommendations.
