Description

Technical Field

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

[0002] Existing air supply control logic for air conditioners has relatively simple control objectives. For example, some automatically adjust the fan speed based on the relationship between the indoor ambient temperature and the user's set temperature; some match the air supply to the indoor windless mode; and some suppress and smooth the air based on the total noise level or fluctuation amplitude. However, the human body's real needs are dynamic, complex, and ever-changing. Existing air supply control logic lacks pattern matching for diverse user needs and usage scenarios, which inevitably leads to insufficient comfort performance of air conditioners.

[0003] For example, when using an air conditioner indoors, users are often in different states, such as static, active, or exercising. In these different states, the user's needs and tolerance for the airflow and noise of the air conditioner vary dynamically. This invention addresses the differentiated needs of users in multiple scenarios by proposing a control method that matches the air supply logic of the air conditioner accordingly. Summary of the Invention

[0004] In order to solve the technical problem in the above-mentioned prior art that the air supply control logic of the air conditioner does not match the actual needs, the present invention proposes a control method and an air conditioner, which effectively improves the uncomfortable experience caused by the cold air of the air conditioner in the cooling mode of the air conditioner.

[0005] The technical solution adopted in the present invention is:

[0006] The present invention provides a method for controlling an air conditioner, characterized in that it comprises the steps of:

[0007] Identify the activity status information of the human body in the room through the recognition module, and determine the current activity mode of the human body based on the activity status information of the human body;

[0008] Calculate the difference between the set temperature and the ambient temperature, switch to different blowing modes corresponding to the current active mode according to the size of the difference temperature, and switch the air guide plate to the blowing gear corresponding to the current blowing mode.

[0009] After calculating the difference between the set temperature and the ambient temperature, the motor gear range corresponding to the current activity mode is switched according to the size of the difference temperature, and then the different blowing feeling modes corresponding to the current activity mode are switched.

[0010] Furthermore, switching the air deflector to a blowing feeling gear corresponding to the current blowing feeling mode specifically includes:

[0011] Obtain a blowing feeling index DR corresponding to a current blowing feeling mode, and obtain a current air outlet quantity and a current blowing temperature of an air conditioner indoor unit;

[0012] Adjust the current angle of the deflector through a preset blowing feeling index DR, air conditioner indoor unit air outlet quantity, blowing temperature, and deflector angle mapping relationship.

[0013] Further, the corresponding motor gear interval under the current active mode is switched according to the size of the difference temperature, and specifically includes:

[0014] Each active mode is preset with a plurality of difference temperature intervals with temperature values increasing in turn, and a motor gear corresponding to each difference temperature interval and increasing in turn in running sound;

[0015] The motor gear is determined according to the difference temperature interval where the current difference temperature is located.

[0016] Further, the active mode specifically includes: a static mode, a normal mode, and a motion mode;

[0017] The motor gears corresponding to the three difference temperature intervals with temperature values increasing in turn in the static mode are respectively a silent three-gear position, a silent two-gear position, and a silent one-gear position;

[0018] The motor gears corresponding to the three difference temperature intervals with temperature values increasing in turn in the normal mode are respectively a silent two-gear position, a silent one-gear position, and a noise one-gear position;

[0019] The motor gears corresponding to the three difference temperature intervals with temperature values increasing in turn in the motion mode are respectively a silent one-gear position, a noise one-gear position, and a noise two-gear position;

[0020] And the motor speeds corresponding to the silent three-gear position, the silent two-gear position, the silent one-gear position, the noise one-gear position, and the noise two-gear position increase in turn.

[0021] Further, the corresponding different blowing feeling mode under the current active mode is switched according to the size of the difference temperature, and specifically includes:

[0022] Each active mode is preset with a plurality of difference temperature intervals with temperature values increasing in turn, and at least two blowing feeling modes corresponding to different blowing feeling indexes DR; each difference temperature interval corresponds to a blowing feeling mode, and the higher the temperature value corresponding to the difference temperature interval, the greater the blowing feeling index DR of the blowing feeling mode corresponding to the difference temperature interval, or the same as the blowing feeling index DR of the blowing feeling mode corresponding to the previous level difference temperature interval.

[0023] The blowing feeling mode is determined according to the difference temperature interval where the current difference temperature is located.

[0024] Further, the activity mode specifically comprises: a static mode, a normal mode and a motion mode.

[0025] The three temperature value intervals of the static mode in ascending order correspond to the blowing feeling modes of no blowing feeling mode, no blowing feeling mode and low blowing feeling mode.

[0026] The three temperature value intervals of the normal mode in ascending order correspond to the blowing feeling modes of no blowing feeling mode, low blowing feeling mode and medium blowing feeling mode.

[0027] The three temperature value intervals of the motion mode in ascending order correspond to the blowing feeling modes of medium blowing feeling mode, medium blowing feeling mode and high blowing feeling mode.

[0028] And the wind feeling indexes DR corresponding to the no blowing feeling mode, the low blowing feeling mode, the medium blowing feeling mode and the high blowing feeling mode are in ascending order.

[0029] Preferably, the activity state information of the indoor human body is recognized by the recognition module, and the current activity mode of the human body is determined according to the activity state information of the human body, specifically:

[0030] The motion parameters of the human body are detected by the millimeter wave radar to emit and receive electromagnetic waves, and the current activity mode of the human body is determined according to the threshold interval in which the motion parameters are located.

[0031] Specifically, the air conditioner detects the current time.

[0032] If the current time is in the time period corresponding to the daytime mode, the recognition module is enabled, and the activity state information of the indoor human body is recognized by the recognition module.

[0033] If the current time is in the time period corresponding to the night mode, the current activity mode is directly set to the static mode.

[0034] The application also proposes an air conditioner using the control method of the air conditioner to control the angle of the air deflector.

[0035] Compared with the prior art, the application has the following advantages:

[0036] By dynamically matching the activity mode of the human body and the temperature difference, the problem of uncomfortable body feeling or high energy consumption caused by fixed blowing mode can be avoided. The adaptive matching of the user's diversified composite experience demand for different levels of mute level and blowing feeling in the static, normal and motion scenes further improves the use comfort of the air conditioner.

[0044] In order to make the technical problems to be solved by the present application, the technical solutions and beneficial effects more clearly, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0045] The principles and structures of the present application will be described in detail below in combination with the drawings and embodiments.

[0046] The air supply control logic of the existing air conditioner is relatively single in control target, for example, some are automatically adjusted in wind speed according to the relationship between the indoor environment temperature and the user set temperature, some are matched in air supply based on the indoor windless mode, and some are suppressed and smoothed based on the total value or fluctuation amplitude of noise. However, the real demand of human body is dynamic, complex and changeable. The existing air supply control logic lacks the mode matching of multiple demands and multiple use scenarios of users, which inevitably leads to the insufficient comfort of the air conditioner.

[0047] To this end, the present application proposes a control method of an air conditioner, comprising the steps of:

[0048] The recognition module identifies the activity status of people indoors and determines their current activity mode based on this information. Specifically, it uses sensors or image recognition technology to obtain information such as human movements, positions, and postures, and then determines the current activity mode (such as sitting still, walking, exercising, etc.) to adapt to the comfort needs in different scenarios.

[0049] Calculate the difference between the set temperature and the ambient temperature, switch to a different blowing mode corresponding to the current active mode according to the size of the temperature difference, and switch the air deflector to the blowing position corresponding to the current blowing mode;

[0050] By dynamically matching human activity patterns with temperature differences, we can avoid the discomfort and excessive energy consumption caused by fixed air supply methods. For example, during exercise, when the human body's perception of noise and air volume decreases, higher air volumes can be used to maintain comfort while quickly lowering the ambient temperature. Conversely, in situations like sitting quietly, weaker air flow is used when the temperature difference is smaller to reduce airflow disturbances. This method, through real-time sensing and intelligent adjustment, improves air conditioning operation accuracy and user comfort, while also optimizing energy efficiency.

[0051] In a specific embodiment, after calculating the difference between the set temperature and the ambient temperature, the motor gear range of the fan corresponding to the current active mode is switched according to the size of the difference temperature, and then the different blowing feeling modes corresponding to the current active mode are switched.

[0052] Specifically: when the temperature difference is large, the motor gear range is increased to increase the air volume, and the motor gear needs to match the activity mode. For example, in sports mode, users are less aware of noise and are more concerned about cooling efficiency. At this time, even if the temperature difference is large, the motor gear can be increased to a higher range (such as noise level 1 or noise level 2), and the corresponding blowing feeling mode can be used to enhance the human body's wind sensation. In sitting or resting mode, users are more sensitive to noise and wind. At this time, even if the temperature difference is large, the motor gear is preferentially limited to the medium and low range to reduce noise, and at the same time, it switches to a weaker blowing feeling mode to avoid affecting human comfort.

[0053] By controlling the motor position and the airflow mode in steps, rapid cooling requirements and scene adaptability are both achieved. This approach, through dual-layer parameter linkage, precisely matches air conditioning performance with user activity while avoiding the unbalanced experience caused by a single control logic.

[0054] In a specific embodiment, switching the air deflector to a blowing feeling gear corresponding to the current blowing feeling mode specifically includes:

[0055] Get the wind sensation index DR corresponding to the current wind sensation mode, and simultaneously get the current air volume and wind temperature of the air conditioner indoor unit.

[0056] Specifically, the corresponding wind sensation index (DR) value is determined based on the selected wind sensation mode (such as no wind sensation mode, medium wind sensation mode, etc.). This index comprehensively reflects the impact of wind speed, temperature, and turbulence intensity on physical comfort. At the same time, the actual air volume value and current air supply temperature of the indoor unit outlet are collected in real time.

[0057] The current angle of the air deflector is dynamically adjusted by mapping the preset wind sensation index (DR), air volume, air temperature, and the angle of the air deflector. This mapping is based on experimental data on airflow coverage, wind speed attenuation, and human body sensation using different parameter combinations. For example:

[0058] When the DR value is high (such as the strong wind state corresponding to the high blowing feeling mode), the air volume is large and the temperature is low, the air guide angle is expanded to quickly and efficiently transport airflow, improving the directional cooling efficiency;

[0059] When the DR value is low (such as the weak wind mode corresponding to the low blowing feeling mode), the air volume is small and the temperature is close to the ambient temperature, the angle of the air guide plate is narrowed and the air supply is in a close-fitting air supply mode to prevent cold air from blowing directly on people and causing discomfort.

[0060] Through coordinated parameter control, the deflector angle can be adjusted to match the current airflow requirements. For example, in high-wind mode for exercise, high DR values ​​and large airflow volumes require wide-angle deflection. In low-wind mode for quieter scenes, low DR values ​​and low airflow volumes are combined with narrow-angle deflection to prevent cold air from reaching people. This multi-parameter collaborative optimization ensures the adaptability of airflow modes to human activity while avoiding localized overcooling or insufficient coverage caused by single-angle control, thereby improving overall comfort and energy efficiency.

[0061] Specifically, different blowing sensation modes correspond to different blowing sensation indexes DR.

[0062] Specific as Figure 5 、 6 As shown, in the human activity area (0.1 ~ 1.6m), the blowing sensation index DR (the percentage of dissatisfied people due to the airflow taking away the body heat) of each detection point in GB / T33658-2017 is calculated. The specific method is: measure the temperature and wind speed of each detection point during the acquisition time, and then calculate the index DR of the detection point by the calculation formula in GB / T33658-2017. By changing the air volume, air temperature, and air guide angle, a large number of data sets can be obtained. For these data sets, the intrinsic mapping relationship between the blowing sensation index DR (the blowing sensation index DR used for control in the present invention refers to the maximum blowing sensation index DRmax in the human activity area) and the air volume, air temperature, and air guide angle can be obtained through neural networks or other algorithms.

[0063] For the sake of simplicity, we use polynomials to perform regression coupling analysis between the above variables, and we can obtain the following correlation formula:

[0064] DR max =A0+A1θ+A2Q+A3T+A4θ 2 +A5Q 2 +A6T 2 +A7θQ+A8θT+A9QT

[0065] Where: Ai is the regression coefficient, θ is the angle of the air guide plate, Q is the air volume, and T is the air temperature.

[0066] In a specific embodiment, each activity mode presets three temperature difference intervals with successively increasing temperature values. For example, the temperature difference is divided into a "small temperature difference interval", a "medium temperature difference interval" and a "large temperature difference interval", and each interval corresponds to a motor gear with successively increasing operating sound. Specifically: the temperature difference thresholds in different activity modes are set through experiments or user scenario data. For example, in the sitting mode, the small temperature difference interval is 0-2°C, the medium temperature difference interval is 2-4°C, and the large temperature difference interval is above 4°C. In the sports mode, the interval threshold may be appropriately expanded due to the need for rapid cooling. The motor gear corresponding to each temperature difference interval needs to match the characteristics of the activity mode. For example, the large temperature difference interval of the sports mode can correspond to a high-noise high gear to increase the air volume, while the large temperature difference interval of the sitting mode limits the gear upper limit to reduce noise interference.

[0067] The system automatically determines the appropriate motor gear based on the temperature range the current temperature difference falls within. For example, if the system detects a 5°C temperature difference in exercise mode, it identifies the wide temperature range and activates the preset high gear to accelerate cooling. However, if the temperature difference is also 5°C in stationary mode, the system may only shift to the medium gear to balance cooling efficiency and noise control.

[0068] By presetting logic for tiered temperature ranges and gears, motor operating parameters can be matched to scenario requirements. For example, in static mode, even with large temperature differences, the gear is limited to the low-noise range to avoid disrupting rest. Meanwhile, in sports mode, suitable for gatherings and activities, medium-to-high noise levels ensure communication clarity while quickly adjusting the ambient temperature. This approach, through a stepped temperature response mechanism, strikes a balance between ensuring rapid cooling and scenario adaptability, thereby improving the user experience and reducing energy waste.

[0069] Specifically, the activity modes include static mode, normal mode, and sports mode. Each mode has three preset temperature ranges with increasing temperature values ​​and corresponds to different levels of motor gears to match the scene requirements:

[0070] Still mode (such as rest and sleep scenes):

[0071] Small temperature difference range (such as 0-2℃) → Quiet level 3 gear (lowest speed, minimum noise);

[0072] Medium temperature range (e.g. 2-5°C) → Quiet Secondary gear (medium-low speed, second lowest noise);

[0073] Large temperature difference range (such as above 5℃) → Quiet level 1 (medium speed, medium noise).

[0074] Normal mode (such as daily activities or office scenes):

[0075] Small temperature difference range (such as 0-2℃) → Quiet second gear (medium-low speed, second lowest noise);

[0076] Medium temperature range (e.g. 2-5°C) → Quiet 1st gear (medium speed, medium noise);

[0077] Large temperature difference range (such as above 5℃) → Noise level 1 (higher speed, acceptable noise).

[0078] Sports mode (such as intense activity or rapid cooling requirements):

[0079] Small temperature difference range (such as 0-2℃) → Quiet level 1 (medium speed, medium noise);

[0080] Medium temperature range (e.g. 2-5°C) → Noise Level 1 (higher speed, acceptable noise);

[0081] Large temperature difference range (such as above 5℃) → Noise Level 2 (highest speed, higher noise).

[0082] Relationship between gear speed and noise:

[0083] The motor speed and operating sound of all gears follow the following increasing order:

[0084] Quiet Level 3 < Quiet Level 2 < Quiet Level 1 < Noise Level 1 < Noise Level 2. This means the smaller the number in the gear name, the lower the speed and the quieter the noise (e.g., "Quiet Level 3" is quieter than "Quiet Level 2"). The noise difference between motor gears can be set to 3-5dB, and the difference between gears can be unequal. The specific allocation should be based on the operating noise range of the corresponding product.

[0085] This method achieves precise adaptation of air-conditioning performance to user needs by deeply binding gear speed, noise level and scene characteristics (such as user noise sensitivity and cooling urgency), avoiding excessive energy consumption in silent scenes and ensuring rapid response capabilities in high-demand scenes.

[0086] In a specific embodiment, each activity mode presets multiple differential temperature intervals (such as three intervals) with successively increasing temperature values, and configures at least two wind sensation modes with different wind sensation indices DR. Each differential temperature interval corresponds one-to-one to a wind sensation mode, and the higher the temperature value corresponding to the differential temperature interval, the DR value of the wind sensation mode in that interval is not less than the DR value of the previous interval (i.e., the DR is allowed to increase or remain the same). The wind sensation intensity is dynamically adjusted according to the user's activity mode and temperature difference, and is linked to parameters such as the wind deflector angle and motor speed to form a multi-dimensional control closed loop, thereby improving overall energy efficiency and user experience.

[0087] The specific implementation is as follows:

[0088] Take the static mode, normal mode and sports mode as examples:

[0089] Still mode (such as sleeping scene):

[0090] Temperature range division: for example, 0-2°C (small temperature difference), 2-5°C (medium temperature difference), and above 5°C (large temperature difference);

[0091] Blowing mode configuration:

[0092] 0-2℃→No-wind mode (DR=5) (maintains extremely low wind feeling while ensuring quietness and comfort);

[0093] 2-5℃→No-wind mode (DR=5) (maintains extremely low wind sensation while ensuring quietness and comfort);

[0094] Above 5°C → Low wind speed mode (DR=15) (moderately increase wind speed to accelerate cooling).

[0095] Normal mode (such as daily activities):

[0096] Temperature range division: for example, 0-2℃, 2-5℃, and above 5℃;

[0097] Blowing mode configuration:

[0098] 0-2℃→No wind mode (DR=5);

[0099] 2-5℃ → Low wind mode (DR=15);

[0100] Above 5°C → Medium wind speed mode (DR=40) (fast cooling at high wind speed).

[0101] Movement patterns (e.g., vigorous activity):

[0102] Temperature range division: for example, 0-2℃, 2-5℃, and above 5℃;

[0103] Blowing mode configuration:

[0104] 0-2℃→Medium wind mode (DR=40) (High wind speed for fast cooling)

[0105] 2-5℃→Medium wind mode (DR=40) (High wind speed for fast cooling)

[0106] Above 5℃ → High wind speed mode (DR>40) (fast cooling at high wind speed).

[0107] The wind intensity is dynamically adjusted according to the user's activity pattern and temperature difference, and linked with parameters such as the wind deflector angle and motor speed to form a multi-dimensional control closed loop, thereby improving overall energy efficiency and user experience.

[0108] like Figures 1 to 3 As shown, the following specific embodiment is the control of three modes combined with motor gear and wind sense mode:

[0109] When the static mode processing module (built-in module of the air conditioning control panel) is started, ΔT = Tsetting - Tambient, which is the difference between the calculated setting temperature and the ambient temperature.

[0110] If ΔT<=ΔT1 (eg, ΔT1=5°), it is further determined whether ΔT is less than ΔT2 (eg, ΔT2=2°).

[0111] If △T<=△T2, it means that the indoor ambient temperature is very close to the set temperature and the user is in a static state. At this time, the human comfort experience is the highest, and the best quiet level and the weakest blowing experience are required. Therefore, the system should control the motor to switch to the quiet level 3 gear and output the capacity according to the minimum air volume. At this time, the room itself has sufficient cooling capacity and the capacity is mainly to maintain the set temperature. The system enters the quiet level 3 gear, and the air guide plate switches to the no-blowing windshield, so that the human activity area enters the no-blowing mode;

[0112] If △T2<△T<△T1, the indoor ambient temperature is still a certain distance away from the set temperature. The temperature drop rate, quiet level, and wind-blowing experience in the static state need to be comprehensively considered. Therefore, the system should control the motor to switch to medium and low gears, and appropriately increase the power output according to the small air volume. The system enters the quiet second gear to maintain the best overall quiet experience. At the same time, the air deflector switches to a no-blowing windshield to keep the human activity area in a no-blowing mode.

[0113] If AT > AT1, at this time the indoor environment temperature is far from the set temperature, the air volume needs to be further increased to accelerate the room capacity output and increase the temperature drop rate, but the noise and blowing feeling of the human body in the static state need to be considered. Therefore, the system should control the motor to switch to the middle gear, and the capacity output is strengthened according to the medium air volume, the system enters the silent first gear, and the overall noise experience is maintained slightly. At the same time, the air deflector is switched to the low blowing feeling gear, so that the human body activity area is in a slight blowing feeling state, and a certain cooling experience of the human body is maintained under a high environment temperature (i.e. insufficient room cooling), while avoiding causing an uncomfortable reaction of the human body; When the above mode is running, the system detects and judges AT all the time, and automatically switches the air supply logic according to the position interval of AT at any time;

[0114] When the normal mode processing module is started, the system first detects the difference between the user set temperature and the environment temperature, that is, AT = Tset - T environment;

[0115] If AT <= AT1 (such as AT1 = 5°), it is further determined whether AT is less than AT2 (such as AT2 = 2°).

[0116] If AT <= AT2, it indicates that at this time the indoor environment temperature is very close to the set temperature, the user is in a low-frequency activity state, the human body heat production increases, and the cooling experience is reduced compared with the static state, but since the overall environment temperature is close to the set temperature, it is still necessary to avoid the discomfort caused by cold wind blowing. In addition, the noise sensitivity of the human body in this state has a certain decline. Therefore, at this time, a better silent level and the weakest blowing feeling experience should be configured. Therefore, the system should control the motor to switch to the middle-low gear, appropriately increase the air volume, strengthen the indoor air circulation speed, maintain a better human cooling experience, and at the same time the system enters the silent second gear, the air deflector is switched to the no blowing feeling gear, and the human body activity area enters the no blowing feeling mode;

[0117] If AT2 < AT < AT1, at this time the indoor environment temperature is still a certain distance from the set temperature, and the temperature drop rate, silent level and blowing feeling experience are comprehensively considered. The system should control the motor to switch to the middle gear, and the capacity output is strengthened according to the medium air volume to increase the temperature drop rate. At the same time, the system enters the silent first gear, and the overall noise experience is maintained slightly, and the air deflector is switched to the low blowing feeling gear, so that the human body activity area is in a slight blowing feeling state, and the cooling experience is improved;

[0118] If △T>△T1, the indoor ambient temperature is far from the set temperature, and the air volume needs to be further increased to accelerate the room capacity output and increase the temperature drop rate. Since the temperature in the room is high at this time, the human body's demand for a cool feeling experience is more urgent, and the tolerance for noise is further improved. Therefore, the system considers controlling the motor to switch to high gear, increasing the capacity output according to the larger air volume, and the system enters the first gear of noise, and the overall noise experience is certain. In addition, the air guide plate should be switched to a medium blowing wind shield to put the human activity area in a certain degree of blowing state, and maintain the human body's obvious cool feeling at a higher ambient temperature; when the above mode is running, the system will detect and judge △T throughout the process, and automatically switch the air supply logic according to the position range of △T at any time;

[0119] When the motion mode processing module is activated, the system first detects the difference between the user set temperature and the ambient temperature.

[0120] △T=Tsetting-Tenvironment. If △T<=△T1 (such as △T1=5°), then further determine whether △T is less than △T2 (such as △T2=2°). If △T<=△T2, it means that the indoor ambient temperature is very close to the set temperature, but the user is in a high-frequency motion state at this time, and the body generates a lot of heat. The cooling experience is significantly weakened compared to the static state. At this time, a certain blowing feeling is needed to bring a sufficient cooling experience. At the same time, the ambient noise level rises in the motion state, and the human body's sensitivity to air-conditioning noise is further weakened. At this time, a slight noise level and an appropriate blowing feeling should be maintained. Therefore, the system should control the motor to switch to the middle gear, maintain a medium air volume, and maintain a certain degree of indoor air circulation speed. At the same time, the system enters the silent first gear, and the wind deflector switches to the medium blowing windshield, so that the human activity area is in a certain degree of blowing state, maintaining a better human cooling experience;

[0121] If △T2<△T<△T1, the indoor ambient temperature is still some distance away from the set temperature. The cooling rate needs to be increased rapidly during exercise, but excessive cold air should also be avoided. Therefore, the system should control the motor to switch to high gear, increasing the output capacity according to the larger air volume to achieve rapid cooling. The system enters the first gear of noise level to maintain a certain overall noise experience. At the same time, the air deflector switches to the medium wind-sensing windshield, so that the human activity area is always in a certain degree of blowing state, maintaining a cool experience.

[0122] If △T > △T1, at this time the indoor environment temperature is far away from the set temperature, and since the room temperature is high at this time and the human body heat production is huge, at this time the maximum temperature drop rate should be prioritized to quickly improve the human body's experience demand for coolness. Therefore, the system considers switching the motor to an ultra-high gear, maximizing the ability output according to the maximum air volume, and the system enters the noise second gear, and the whole is in a high noise experience. In addition, the air deflector should be switched to a high-blowing air feeling gear, so that the human body activity area is in a high wind feeling state, ensuring that in a high environment temperature, the human body in a moving state can maintain a clear cool feeling experience; When the above mode is running, the system detects and judges △T throughout the process, and automatically switches the air supply logic according to the position interval of △T at any time.

[0123] In specific embodiments, the motion parameters of the human body are detected by transmitting and receiving electromagnetic waves by the millimeter wave radar, which can be, for example, average speed, average acceleration, and breathing frequency (the average speed and average acceleration can be the average of multiple millimeter wave radars or the average in a time period, or the breathing frequency threshold interval can be determined according to the average speed and average acceleration first), which is specifically calculated by transmitting high-frequency electromagnetic waves and analyzing the change of the return frequency;

[0124] Specifically, a plurality of average speed threshold intervals, a plurality of average acceleration threshold intervals, and a plurality of breathing frequency threshold intervals can be preset, and each activity mode corresponds to an average speed threshold interval, an average acceleration threshold interval, and a breathing frequency threshold interval (which is equivalent to a breathing frequency threshold interval corresponding to an average speed threshold interval and an average acceleration threshold interval);

[0125] Then, the activity mode of the current human body is determined according to the threshold interval of each motion parameter (or the activity mode of the current human body can be determined according to the preset breathing frequency threshold interval in which the breathing frequency of the human body is located).

[0126] For example, the speed is divided into three modes: static mode, normal mode, and motion mode, and the specific threshold interval and mode correspondence are shown in the following table.

[0127]

[0128]

[0129] It should be noted that the above is only an example, and the specific threshold should be trained by a large amount of labeled data to automatically extract the best threshold matching the corresponding mode. Even further, different portrait control parameters can be extracted according to different characters (men, women, old people, and children).

[0130] By using millimeter-wave radar to monitor human motion in real time and combining it with preset threshold interval divisions, the actual intensity of the user's behavior can be identified, making the air-conditioning operation more in line with actual needs and reducing energy waste or physical discomfort caused by fixed modes.

[0131] In a specific embodiment, Figure 4 As shown, when the air conditioner is running in adaptive mode, it detects the current time. Specifically, the real-time time can be obtained through the built-in system clock of the air conditioner or the network time protocol;

[0132] Determine whether the current time is in the preset day mode or night mode time period (for example, the day mode can be set to 8:00-22:00, and the night mode is 22:00-8:00, and the specific time period can be adjusted according to user needs);

[0133] If the current time is daytime mode, the recognition module (such as a camera, infrared sensor, or millimeter-wave radar) is activated to monitor the activity status information of people indoors in real time, and the corresponding activity mode (such as still, normal, or exercise mode) is determined based on the activity status information;

[0134] If the current time is night mode, the activity mode is directly preset to still mode (at this time, the working intensity of the recognition module is turned off or reduced to avoid noise or light interference caused by continuous monitoring at night).

[0135] By triggering different activity mode determination logic based on time conditions, the system can reduce energy consumption and interference during sleep periods during nighttime activity detection. It also defaults to static mode to avoid disturbing users. During the day, the system maintains dynamic recognition and adjusts the airflow strategy based on actual activity intensity. This approach reduces unnecessary sensor load at night while ensuring personalized control when needed, balancing energy efficiency and user comfort.

[0136] In addition, it should be noted that no matter whether the air conditioner is currently in static mode, normal mode or sports mode, if there is an external instruction, it will act according to the external instruction, such as the user directly issuing a control instruction for the air deflector.

[0137] The present invention also proposes an air conditioner that utilizes the aforementioned control method and incorporates the millimeter-wave radar described in the corresponding embodiment. Based on the control logic of this invention, the air conditioner can adaptively match the user's diverse and complex experience requirements for different levels of quietness and airflow in static, normal, and active scenarios, further enhancing user comfort.
