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 fan, and the use experience of the user is promoted.
In addition, the environmental parameters typically include, but are not limited to, temperature, humidity, air volume, etc. within the target area, therefore, by detecting the ambient temperature in the target area at specified time intervals and executing a specified blowing mode based on the detection result of the ambient temperature, wherein the environment temperature can reflect the average temperature of the target area, the temperature change rule and the temperature of the designated position, the designated position can be the ceiling, the ground, the sofa, the bed, the writing desk and the like, but not limited thereto, the demand degree of the user for the heating mode is indirectly determined, which not only improves the blowing experience of the user, but also is beneficial to improving the energy efficiency of the air conditioner such as, controlling the air outlet to blow to the feet of the user when the temperature of the ground of the target area is lower than 10 ℃, and controlling the air outlet to blow air to the ceiling of the target area when the temperature of the ground of the target area is determined to be higher than 20 ℃.
Optionally, after entering the heating mode, the ambient temperature in the target area is detected at specified time intervals.
The specified time interval may be determined based on a historical operating record of the air conditioner, or may be determined according to the ambient temperature, but is not limited to the two determination methods, and in addition, the specified time interval may be a fixed preset value, or may be a variable value adjusted according to the detection time length and the detection value of the ambient temperature.
It is worth pointing out that, before blowing air to the feet of the user, the air conditioner can detect the positions of the feet of the user based on image acquisition or wireless communication detection or sound detection, and the specific implementation manner is as follows:
(1) the image acquisition is realized through a camera arranged on the air conditioner, the acquired image can be an infrared image or a color image, the reliability and the accuracy are higher, the foot position of a user can be determined, and interference objects such as furniture, ornaments, movable household appliances, pets, lamps and the like can be eliminated based on the image information, at the moment, 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 the hardware loss of the air conditioner are reduced.
(2) The Wireless communication detection mode comprises infrared, radar, Bluetooth, Wi-Fi (Wireless Fidelity, Wireless local area network based on IEEE 802.11b standard) and the like, and in addition, the Wireless communication detection can be realized through data interaction between the wearable equipment and the air conditioner.
(3) One way of implementing sound detection is to provide at least four sound collectors on the panel of the air conditioner, and the speed of sound propagation is known, so that the position of the user can be determined based on the time difference of sound information received by the four sound collectors, and the position of the feet of the user can be indirectly determined.
Specifically, any one of the blowing assemblies may include two fans (axial flow fans or diagonal flow fans) arranged in a contra-rotating manner, any one of the fans may rotate in a first direction, that is, blow air to the evaporator, and any one of the fans may also rotate in a second direction (opposite to the first direction), that is, blow air to the air outlet, so that the air supply mode of the air conditioner defined by the present application may be narrow-angle air supply or wide-angle air supply, when wide-angle air supply is performed to the target area, the rotation speed of the fan close to the evaporator is usually greater than or equal to the rotation speed of the fan close to the air outlet, especially the rotation speed of the fan close to the air outlet plays an air-dispersing effect, so as to achieve wide-angle air supply, and simultaneously expand the field angle of the air supply range is enlarged, and similarly, when narrow-angle air supply is performed to the target area, the rotation speed of the fan close to the evaporator is usually less than the rotation speed of the fan close, and further narrow-angle air supply is realized, and air is supplied to a target area at a farther distance.
When the narrow-angle air supply is carried out, the air output by the air outlet is blown along a specified direction and is dispersed until a specified distance is reached, the specified distance corresponds to the rotating speed of the fan, and when the wide-angle air supply is carried out, the air is dispersed after being blown out of the air conditioner through the air outlet.

In this scheme, under appointed air supply mode, through control the aviation baffle is swung downwards, can promote the effect of blowing hot-blast to the ground of target area, because the subassembly of blowing that is close to the top of air conditioner is farther from ground, consequently, the pivot angle of control aviation baffle reduces along with the position of air outlet risees, can make the hot-blast of all air outlets of air conditioner blow to ground more, and then promotes the user and experience the use of heating the mode.
Among the above-mentioned technical scheme, air guide component includes at least one appointed the top edge's of air outlet wind-guiding strip, appointed air outlet leans on the air conditioner bottom sets up, wind-guiding strip can the horizontal hunting under the appointed air supply mode, wind-guiding strip with the contained angle between the front panel of air conditioner marks as the yaw angle, the yaw angle of wind-guiding strip is along with the wind speed of air outlet risees and reduces.
In this scheme, because a plurality of air outlets blow to the earth's surface simultaneously, hot-blast upwards diffusion usually, the air-out between a plurality of air outlets if intermix, can influence the air-out temperature, consequently, in order to promote the heating efficiency of air conditioner, consequently, through control the horizontal pivot angle of wind-guiding strip reduces along with the wind speed of air outlet risees, has reduced the hot-blast upwards of air outlet effectively and has blown, and then has reduced the hot-blast mixture between the air outlet to promote effectively and blow hot-blast effect to the earth's surface.
