The preset environment comfortable temperature interval can be set differently according to actual needs, for example, Tao is set to be more than or equal to 10 ℃ and less than or equal to 20 ℃. Assuming that the outdoor ambient temperature Tao is 15 ℃, the air conditioner 100 maintains a standby state; assuming that the outdoor ambient temperature Tao is 25 ℃, the air conditioner 100 enters a refrigeration state, and the human body detection device 181 starts to acquire the blood pressure of the wrist of the human body; assuming that the outdoor ambient temperature Tao is 5 ℃, the air conditioner 100 enters a heating state and the human body detecting device 181 starts to acquire the blood pressure of the wrist of the human body.

The control method of the air conditioner 100 according to the embodiment of the present invention will be described in detail below with reference to the normal diastolic pressure interval of the human wrist diastolic pressure in the cooling state being set to 60mmHg or less DBP < 90 mmHg.
When the acquired wrist diastolic pressure of the human body is less than or equal to 60mmHg and DBP is less than 90mmHg, the air conditioner 100 is controlled to supply air in a natural wind mode. At this time, the yaw blade 160 and the yaw blade 150 are controlled to be in the extreme yaw angle state of the yaw-vertical direction, the yaw blade 160 is rotated to be substantially parallel to the horizontal plane, and the yaw blade 150 is rotated to be substantially parallel to the vertical plane. If the starting is started for the first time, the natural wind mode is entered, and the initial starting positions of the horizontal swinging blades 160 and the vertical swinging blades 150 are in a horizontal, horizontal and vertical state; if the natural wind mode is entered during the operation of the air conditioner 100, the positions of the yaw blades 160 and the vertical blades 150 are adjusted to be restored to the landscape-upright state. After a third predetermined period of time (e.g., 10-15s), the frequency of the compressor 170 is adjusted to operate at a first predetermined frequency (e.g., 36Hz) that is lower than its initial frequency (e.g., 56 Hz). After a fourth predetermined period of time (e.g., 30s-1min), the speed of the fan 120 is adjusted to operate at a first predetermined speed (e.g., 600r/min) that is lower than its initial speed (e.g., 920 r/min). After a second preset time period (e.g., 1min to 1.5min), the rotation speed of the fan 120 is intermittently adjusted, and the fan 120 is controlled to repeat a plurality of rotation speed adjustment cycles in a preset rotation speed interval, wherein in each rotation speed adjustment cycle, the rotation speed of the fan 120 is adjusted by a preset change rotation speed value and is kept for the first preset time period, and then the next rotation speed adjustment cycle is performed. The preset rotation speed interval is, for example, 580r/min-620r/min, the first preset time period is, for example, 30s, and the preset variation rotation speed value is, for example, 20r/min, that is, the rotation speed of the fan 120 is increased or decreased by 20r/min every 30 s. It should be understood that "increase" and "decrease" herein refer to a change in the trend of change when the end of the rotation speed range is reached, and not any change at any time. After a fifth preset time (for example, 1min to 2min), the air deflector 113 is controlled to cover the air outlet 112, so as to realize the micro-hole air outlet. Thereafter, the compressor 170 continues to operate at the first preset frequency and the blower fan 120 continues to perform the intermittent regulation until the air conditioner 100 exits the natural wind mode.
When the obtained wrist diastolic pressure of the human body is larger than or equal to 90mmHg, the horizontal swinging blades 160 and the vertical swinging blades 150 are controlled to supply air at the limit deflection angle, and the air deflector 113 is moved out of the air outlet 112. Specifically, the horizontal swing blade 160 is rotated to be substantially parallel to the horizontal plane, and the vertical swing blade 150 is rotated to be substantially parallel to the vertical plane, so that the air outlet area of the air outlet 112 is maximized. Then, the diastolic pressure of the wrist of the human body is continuously obtained, and whether the diastolic pressure of the wrist of the human body after the sixth preset time period (for example, 5-10min) is still greater than or equal to 90mmHg is judged. If the wrist diastolic pressure of the human body is greater than or equal to 90mmHg, the horizontal swinging blades 160 and the vertical swinging blades 150 are kept to continuously supply air at the limit deflection angle, meanwhile, the fan 120 is controlled to accelerate, the fan is operated at a second preset rotating speed (for example, 950r/min) higher than the initial rotating speed, the compressor 170 is increased in frequency, the fan is operated at a second preset frequency (for example, 61Hz) higher than the initial frequency until the obtained wrist diastolic pressure of the human body is within the normal diastolic pressure range, and then, the components are controlled according to the natural wind mode.

Then, the diastolic pressure of the wrist of the human body is continuously obtained, and whether the diastolic pressure of the wrist of the human body after a seventh preset time period (for example, 5-10min) is less than 60mmHg is judged. If the wrist diastolic pressure of the human body is less than 60mmHg, the horizontal swing blades 160 are kept to supply air at the first longitudinal deflection angle, the vertical swing blades 150 supply air at the first transverse deflection angle, the fan 120 is controlled to decelerate, the compressor 170 is operated at a third preset rotation speed (e.g., 890r/min) lower than the initial rotation speed, the compressor 170 is reduced in frequency, the compressor is operated at a third preset frequency (e.g., 50Hz) lower than the initial frequency until the obtained wrist diastolic pressure of the human body is in the normal diastolic pressure interval, and then the components are controlled according to the natural wind mode.
The control method of the air conditioner 100 according to the embodiment of the present invention will be described in detail with an exemplary manner in which the normal diastolic pressure interval of the diastolic pressure of the wrist of the human body in the heating state is set to 60mmHg ≦ DBP < 90 mmHg.
When the acquired wrist diastolic pressure of the human body is less than or equal to 60mmHg and DBP is less than 90mmHg, the air conditioner 100 is controlled to supply air in a natural wind mode. At this time, the yaw blade 160 and the yaw blade 150 are controlled to be in the extreme yaw angle state of horizontal, vertical, and the yaw blade 160 is rotated to be substantially parallel to the horizontal plane and the yaw blade 150 is rotated to be substantially parallel to the vertical plane. If the starting is started for the first time, the natural wind mode is entered, and the initial starting positions of the horizontal swinging blades 160 and the vertical swinging blades 150 are in a horizontal, horizontal and vertical state; if the natural wind mode is entered during the operation of the air conditioner 100, the positions of the yaw blades 160 and the vertical blades 150 are adjusted to be restored to the horizontal-vertical limit deflection angle state. After a third predetermined period of time (e.g., 10-15s), the frequency of the compressor 170 is adjusted to operate at a first predetermined frequency (e.g., 46Hz) that is lower than its initial frequency (e.g., 76 Hz). After a fourth predetermined period of time (e.g., 30s-1min), the speed of fan 120 is adjusted to operate at a first predetermined speed (e.g., 620r/min) that is less than its initial speed (e.g., 960 r/min). After a second preset time period (e.g., 1min to 1.5min), the rotation speed of the fan 120 is intermittently adjusted, and the fan 120 is controlled to repeat a plurality of rotation speed adjustment cycles in a preset rotation speed interval, wherein in each rotation speed adjustment cycle, the rotation speed of the fan 120 is adjusted by a preset change rotation speed value and is kept for the first preset time period, and then the next rotation speed adjustment cycle is performed. The preset speed interval is, for example, 600r/min to 640r/min, the first preset duration is, for example, 30s, and the preset variable speed value is, for example, 20r/min, that is, the speed of the fan 120 is increased or decreased by 20r/min every 30 s. It should be understood that "increase" and "decrease" herein refer to a change in the trend of change when the end of the rotation speed range is reached, and not any change at any time. After a fifth preset time (for example, 1min to 2min), the air deflector 113 is controlled to cover the air outlet 112, so as to realize the micro-hole air outlet. Thereafter, the compressor 170 continues to operate at the first preset frequency and the blower fan 120 continues to perform the intermittent regulation until the air conditioner 100 exits the natural wind mode.
When the obtained wrist diastolic pressure of the human body is less than 60mmHg, the horizontal swinging blades 160 and the vertical swinging blades 150 are controlled to supply air at a limit deflection angle, and the air deflector 113 is moved out of the air outlet 112. Specifically, the horizontal swing blade 160 is rotated to be substantially parallel to the horizontal plane, and the vertical swing blade 150 is rotated to be substantially parallel to the vertical plane, so that the air outlet area of the air outlet 112 is maximized. Then, the diastolic pressure of the wrist is continuously obtained, and whether the diastolic pressure of the wrist after the eighth preset time period (for example, 5-10min) is still less than 60mmHg is judged.
