In the above technical solution, detecting the relevant information of the user in the target area specifically includes: collecting image information in the target area; analyzing the image information to determine biological feature information corresponding to the user, wherein the biological feature information comprises at least one of face feature information, gait feature information and body contour feature information, and the biological feature information is used for determining the identity of the user or a user group to which the user belongs.

In the scheme, the biometric information is used for identifying the identity of the user or a user group to which the user belongs, so that interfering objects such as furniture, ornaments, movable household appliances, pets, lamps and the like can be eliminated based on the image information, but not limited to the above, so that the biometric information is determined based on the image information by collecting the image information in the target area, on one hand, when the biometric information is detected, the operation parameters are adjusted according to the biometric information, and further, whether the wide-angle air supply or the narrow-angle air supply is performed or not is determined by combining the environmental parameters, which is beneficial to improving the use experience of the user, and on the other hand, when the target object is detected to have no biometric information, the operation parameters of the air conditioner do not need to be adjusted, or the air conditioner is directly controlled to stop, so as to reduce the power consumption and hardware loss of the air conditioner.

Wherein, the biological characteristic information at least comprises the following parts:

(1) the gait feature information mainly includes the posture features of the user in the walking process, and may include leg movement frequency and amplitude, double-arm swinging frequency and amplitude, body trend, walking speed, stepping amplitude, and the like, but is not limited thereto, and the gait recognition is to recognize the above posture features, so as to recognize the identity information of the user, when detecting the gait feature information, the distance between the user and the internal unit of the air conditioner may be larger than a certain distance (for example, 4 meters away), and is mainly used for distinguishing the user groups of the old, the infant, the adult, and the like, and has no requirement on the posture of the user.

(2) The face feature information mainly includes facial feature contours, three-dimensional shapes, wrinkle textures, skin colors and the like of the user, but is not limited to the facial feature information, when the face feature information is detected, the distance between the user and an internal unit of the air conditioner is usually smaller than a certain distance (for example, within 4 meters), the face of the user is required to be over against a camera on the air conditioner, and the face feature information can be used for detecting the identity of the user, and the accuracy is high.

In the above technical solution, detecting the relevant information of the user in the target area specifically further includes: collecting sound information in the target area; and analyzing the sound information to determine a voiceprint characteristic corresponding to the user, wherein the voiceprint characteristic is used for determining the identity of the user or a user group to which the user belongs.

In this scheme, through gathering sound information to analysis sound information is in order to confirm the vocal print characteristic that corresponds, is favorable to improving the degree of accuracy of carrying out the discernment to the user, and then adjusts the operating parameter of air conditioner based on the recognition result to the user, and further, combines environmental parameter to confirm whether carry out wide angle air supply or narrow angle air supply, thereby has promoted user's use and has experienced.

The voiceprint characteristic information mainly comprises a sound wave spectrum included in sound information detected by an electro-acoustic instrument, and the pitch, the duration, the tone color and the tone intensity of each user are obviously different when the user vocalizes, so that the waveform of collected sound information is reflected as the difference of the wavelength, the frequency, the amplitude and the rhythm, when the sound information is converted into a spectrum graph, the voiceprint characteristic is obtained, and the voiceprint characteristic has the identity recognition effect like a fingerprint.

In the above technical solution, detecting the relevant information of the user in the target area specifically further includes: transmitting an infrared signal to the target area and receiving a corresponding reflected signal; and determining the number and the spatial orientation of the user according to the time difference between the infrared signal and the reflected signal.

In the scheme, based on the poor penetrating power of the infrared signals and the known propagation speed, the number and the spatial orientation of the users can be determined through the time difference between the infrared signals and the reflected signals, and then the operation parameters of the air conditioner are adjusted based on the identification result of the users, and further whether the air conditioner is subjected to wide-angle air supply or narrow-angle air supply is determined by combining with the environment parameters, so that the use experience of the users is improved.

In the above technical solution, the operation parameter includes at least one of an operation mode, a target temperature, and an air supply parameter, the environment parameter includes an environment temperature and/or an environment humidity, and the air supply parameter includes an air speed and/or an air direction.

In this embodiment, the operation mode includes, but is not limited to, a cooling mode, a heating mode, a dehumidifying mode, and the like.

In the above technical solution, according to the environmental parameter, the operating parameter, and the relevant information of the user, it is determined whether to control the counter-rotating fan to perform wide-angle air supply or narrow-angle air supply to the target area, and the method specifically includes: if the number of the users in the target area is determined to be more than or equal to two according to the relevant information of the users, and/or the target area is determined to have no appointed users, calculating the absolute value of the temperature difference between the target temperature and the environmental temperature; judging whether the absolute value of the temperature difference is smaller than or equal to a temperature difference threshold value; and if the absolute value of the temperature difference is smaller than or equal to the temperature difference threshold value, controlling the counter-rotating fan to supply air to the target area in a wide-angle mode.

In the scheme, if the number of the users in the target area is determined to be more than or equal to two according to the related information of the users, the number of the users in the target area is more, and the air supply angle or the air supply distance may not meet the use requirements of the users only by adjusting the air supply angle and the air swinging mode of the air deflector, so that whether wide-angle air supply or narrow-angle air supply is adopted is further determined by combining with the absolute value of the temperature difference.

In addition, the designated user generally refers to a special user group, such as the elderly, infants, pregnant women, and the like, but is not limited thereto, and therefore, when it is detected that the special user group does not exist in the target area, the special user group has a low blowing requirement on the air conditioner and a high temperature control effect requirement on the air conditioner, and whether to perform the wide-angle blowing or the narrow-angle blowing depends on the absolute value of the temperature difference, for example, when the absolute value of the temperature difference is less than or equal to the threshold value of the temperature difference, the wide-angle blowing may be performed to improve the blowing feeling of all users in the target area.

Optionally, when the counter-cyclone fan supplies air to the target area at a wide angle, the rotating speed of the counter-cyclone fan close to the evaporator is less than that of the fan close to the inner machine air outlet, all the counter-cyclone fans supply air to the inner machine air outlet, and the counter-cyclone fan close to the inner machine air outlet plays a role in dispersing air so as to realize wide-angle air supply and effectively enlarge the air supply range (opening angle) of the air conditioner.

In the above technical solution, further comprising: according to the environmental parameter, the operation parameter and the relevant information of the user, whether the counter-rotating fan is controlled to carry out wide-angle air supply or narrow-angle air supply on the target area is determined, and the method specifically comprises the following steps: if the number of the users in the target area is determined to be more than or equal to two according to the relevant information of the users, and/or the target area is determined to have no appointed users, calculating the absolute value of the temperature difference between the target temperature and the environmental temperature; judging whether the absolute value of the temperature difference is larger than a temperature difference threshold value or not; and if the absolute value of the temperature difference is larger than the temperature difference threshold value, controlling the counter-rotating fan to supply air to the target area at the narrow angle, or keeping the air supply parameter of the counter-rotating fan unchanged.

In the scheme, if the number of the users in the target area is determined to be less than two according to the related information of the users, the number of the users in the target area is less, and the air supply angle or the air supply distance may not meet the use requirements of the users only by adjusting the air supply angle and the air swinging mode of the air deflector, so that whether wide-angle air supply or narrow-angle air supply is adopted is further determined by combining with the absolute value of the temperature difference.

In addition, when the special user group exists in the target area, the air blowing requirement of the special user group on the air conditioner is high, the temperature control effect requirement on the air conditioner is low, and therefore whether wide-angle air supply or narrow-angle air supply is conducted or not depends on the absolute value of the temperature difference.

Optionally, when the counter-rotating fan supplies air to the target area at a narrow angle, the rotating speed of the counter-rotating fan close to the evaporator is greater than or equal to the rotating speed of the fan close to the inner machine air outlet, all the counter-rotating fans supply air to the inner machine air outlet, and the counter-rotating fan close to the inner machine air outlet plays a role in air gathering, so that air supply at the narrow angle is realized, and the air supply distance of the air conditioner is effectively increased.

In the above technical solution, according to the environmental parameter, the operating parameter, and the relevant information of the user, it is determined whether to control the counter-rotating fan to perform wide-angle air supply or narrow-angle air supply to the target area, and the method specifically further includes: if the number of the users in the target area is determined to be less than two according to the related information of the users, and/or the appointed users exist in the target area, the space direction of the appointed users is obtained; judging whether the air conditioner operates in the cooling mode or the heating mode according to the operation parameters; if the air conditioner is judged to be operated in the refrigeration mode, controlling the counter-rotating fan to supply air to the target area at the narrow angle, so that the air is blown to avoid the space direction of the specified user; and if the air conditioner is judged to be operated in the heating mode, controlling the counter-rotating fan to supply air to the target area in a wide-angle mode, or keeping the air supply parameters of the counter-rotating fan unchanged.

In the scheme, if the number of the users in the target area is determined to be less than two according to the related information of the users, the users in the target area are fewer at this time, and the air supply angle or the air supply distance may not meet the use requirements of the users only by adjusting the air supply angle and the air swinging mode of the air deflector, therefore, by further determining that the air conditioner is operating in the cooling mode, in order to improve the non-wind experience of the user, the air outlet angle of the air deflector can be adjusted while controlling the narrow-angle air supply so as to avoid the spatial direction of the designated user as much as possible, in addition, in order to allow the user to be more blown with the hot wind when it is further judged that the air conditioner is operated in the heating mode, therefore, when the air supply is controlled to be carried out in a wide angle, the air outlet angle of the air guide plate can be adjusted, namely, the air supply range is expanded, and simultaneously, hot air in a heating mode is blown to a specified user more.

In the above technical solution, if at least one counter-rotating fan is disposed between the inner machine air outlet and the evaporator, the fan close to the inner machine air outlet is regarded as an inner fan, and the fan close to the evaporator is regarded as an outer fan, and the operation control method further includes: detecting whether a specified air supply instruction is received, wherein the specified air supply instruction is used for controlling the counter-rotating fan to supply air to the target area in a wide angle or in a narrow angle; if an appointed air supply instruction corresponding to the wide-angle air supply is received, adjusting the air speed of the outer fan to be larger than that of the inner fan; and if a specified air supply instruction corresponding to the narrow-angle air supply is received, adjusting the air speed of the outer fan to be less than or equal to the air speed of the inner fan.

In this scheme, through detecting whether receive appointed air supply instruction, need not detect user identity and affiliated user group, can directly carry out wide angle air supply or narrow angle air supply, be favorable to promoting the operating efficiency of air conditioner, specifically, when carrying out the wide angle air supply, the adjustment the wind speed of outer fan is greater than the wind speed of interior fan, also be that outer fan is used in the scattered wind to enlarge air supply scope (opening angle), when carrying out the narrow angle air supply, the adjustment the wind speed of outer fan is less than or equal to the wind speed of interior fan, also be that outer fan is used in gathering the wind, in order to enlarge the air supply distance.

Further, before wide-angle air supply or narrow-angle air supply, the wind direction of the air deflector can be adjusted by combining environmental parameters and operation parameters, for example, when the absolute value of the temperature difference is determined to be larger than the temperature difference threshold, narrow-angle air supply is determined, the air supply angle of the air deflector is adjusted to improve the air supply distance and avoid the user activity area, and similarly, when the absolute value of the temperature difference is determined to be smaller than or equal to the temperature difference threshold, wide-angle air supply is determined, the air supply angle of the air deflector is adjusted, and the air outlet is enlarged to improve the air supply range.

Before the wide-angle air supply or the narrow-angle air supply, the user may be prompted by combining the environmental parameters and the operational parameters, for example, when it is determined that the absolute value of the temperature difference is greater than the temperature difference threshold and the received designated air supply command is the wide-angle air supply, a prompt command is generated, if the user feeds back the confirmation command, the wide-angle air supply is performed to the target area, if the received designated air supply command is the narrow-angle air supply, the narrow-angle air supply is directly performed to the target area, and similarly, when it is determined that the absolute value of the temperature difference is less than or equal to the temperature difference threshold and the received designated air supply command is the narrow-angle air supply, a prompt command is generated, if the user feeds back the confirmation command, the narrow-angle air supply is performed to the target area, and if the received designated air supply command is the wide-angle air supply, the wide-angle air supply is directly performed to the target area.

In the above technical scheme, if the air conditioner is provided with an upper inner machine air outlet and a lower inner machine air outlet which are vertically distributed along a plumb line, the inner fan and the outer fan are arranged between the upper inner machine air outlet and the evaporator, and a fan is arranged between the lower inner machine air outlet and the evaporator, the operation control method further comprises: if an appointed air supply instruction corresponding to the wide-angle air supply is received, adjusting the air speed of the outer fan to be larger than that of the inner fan, and meanwhile, controlling the air speed of the fan in the air outlet of the lower inner machine to be reduced; and if a specified air supply instruction corresponding to the narrow-angle air supply is received, adjusting the air speed of the outer fan to be less than or equal to the air speed of the inner fan, and controlling the air speed of the fan in the air outlet of the lower inner machine to increase or keep unchanged.

In the scheme, if the air conditioner is provided with the upper inner machine air outlet and the lower inner machine air outlet which are distributed up and down along the plumb line, the air at the lower inner machine air outlet can be blown to users with shorter height, such as infant users and users lying on the back more easily, therefore, a counter-rotating fan is not required to be arranged in the lower inner machine air outlet to improve the non-wind-feeling experience of special user groups, in addition, the inner fan and the outer fan are arranged between the upper inner machine air outlet and the evaporator, namely the upper inner machine air outlet can supply air to a target area in a wide angle or in a narrow angle, the air guiding component at the lower inner machine air outlet is matched with the upper air outlet to supply air, for example, when the upper inner machine air outlet supplies air in a wide angle, the air guiding component at the lower inner machine air outlet is adjusted to supply air to the bottom area of the air conditioner, and the bottom area comprises a dead angle of the upper inner machine air outlet to further enlarge the range, when carrying out the narrow angle air feed at last inner machine air outlet, the air guide component of inner machine air outlet under the adjustment to reduce the air output and the wind speed of inner machine air outlet down, directly close down inner machine air outlet and inside fan down even, and then when improving the air supply distance of last inner machine air outlet, promote user's no wind sense and experience.
