In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The first embodiment is as follows:
fig. 1 is a schematic flow diagram of an operation control method according to an embodiment of the present invention.
As shown in fig. 1, an operation control method according to an embodiment of the present invention includes: step S102, detecting body shape characteristic information and position distribution information of a user in a target area; and step S104, determining whether to control the counter-rotating fan to carry out narrow-angle air supply on the target area or not according to the body shape characteristic information and the position distribution information, wherein when the narrow-angle air supply is carried out, air blown out from an air outlet of the inner machine is blown along a specified direction and is dispersed until a specified distance is reached, and the specified distance corresponds to the rotating speed of the counter-rotating fan.
In the scheme, the target area is for the air conditioner, and generally comprises an area which can be detected by a sensor on the air conditioner and an area which is influenced by the operation control parameters, so that the relevant information of a user in the target area is detected and is used as a reference condition for the operation of the cyclone fan, and the use experience of the user is favorably improved.
Specifically, the body shape characteristics of the user can determine the identity and the user group of the user, and whether the counter-rotating fan is controlled to perform narrow-angle air supply on the target area is determined according to the body shape characteristic information and the position distribution information.
It is worth pointing out especially that a contra-rotating fan is arranged between an air outlet of an inner machine of the air conditioner and the evaporator, blades of the contra-rotating fan are arranged in a contra-rotating mode, and a plurality of fans in the cyclone machine work cooperatively to realize wide-angle air supply or narrow-angle air supply.
Specifically, either fan may be rotated in a first direction, i.e., to blow air to the evaporator, or either fan may be rotated in a second direction (opposite the first direction), that is, when the air is blown to the air outlet of the inner machine, when the air is blown to the target area in a wide angle, the rotating speed of the fan (marked as the inner fan) close to the evaporator is usually lower than that of the fan (marked as the outer fan) close to the air outlet of the inner machine, and at the moment, the outer fan plays a role of air dispersion, thereby realizing wide-angle air supply, further improving the field angle of the air supply range, and similarly, when the narrow-angle air supply is carried out to the target area, the rotating speed of the inner fan is generally adjusted to be more than or equal to that of the outer fan, and/or when the difference value between the rotating speed of the inner fan and the rotating speed of the outer fan is adjusted to be less than or equal to a rotating speed difference threshold value, the effect of gathering wind can be realized, namely narrow-angle air supply is carried out on the target area, and the wind is supplied to the target area at a farther distance.
In addition, the operation control method in the above embodiment provided by the present invention may further have the following additional technical features:

In the scheme, the image information is used for extracting gait feature information, face feature information, body contour feature and the like of a user in the target area, and the like are not limited to the above, 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, on one hand, after the user identity or the user group is identified, the narrow-angle air supply is determined by combining position distribution information to determine whether to carry out narrow-angle air supply, so that the use experience of the user is improved, on the other hand, when no user is detected in the target area, the operation parameters of the air conditioner do not need to be adjusted, or the air conditioner is directly controlled to stop, so that the power consumption and hardware loss of the air conditioner are reduced.
(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.
(3) The body shape profile feature information is used to determine height information and/or body width information of the user, but is not limited thereto, and the height information may be used to distinguish an adult user from a designated user, and the body width information may be used to identify a pregnant user.

Finally, the infrared radio frequency detection method is generally to send an infrared signal to a target area and receive a reflected infrared signal, and because the penetration capability of the infrared signal is poor and the propagation speed and the propagation direction are known, the body shape characteristic information and the position distribution information of a user in the target area can be determined through the time difference between the infrared signal and the reflected infrared signal, and then whether narrow-angle air supply is performed or not is determined by combining the body shape characteristic information and the position distribution information of the user, so that the use experience of the user is improved.

In this scheme, when judging that the distance is less than or equal to apart from the threshold value, control carries out the narrow angle air supply to the cyclone, can avoid the wind of blowing to scatter near the casing effectively to reduce near the user's of air conditioner sense of blowing, simultaneously, because the wind of blowing does not weaken, and can blow to farther target area, consequently, be favorable to promoting the temperature control effect in the target area.
In the above technical solution, when the narrow-angle air supply is performed to the cyclone, the air supply direction of the air guide assembly of the air conditioner is adjusted, so that the air blown to the cyclone is avoided from the distribution area of the user, which specifically includes: when narrow-angle air supply is carried out on the cyclone fan, the air supply direction is adjusted upwards, and the included angle between the air guide assembly and the horizontal line is adjusted according to the height information of the appointed user, wherein the included angle is positively correlated with the height information.
