When the air conditioner 100 of the embodiment of the present invention is in use, when the user wearing the smart bracelet 300 is within the Wi-Fi matching range of the indoor unit, the air conditioner 100 automatically enters the standby state, and then the outdoor environment temperature detection device 182 detects the outdoor The ambient temperature Tao is to control the air conditioner 100 to enter different states based on the comparison between the outdoor ambient temperature Tao and the preset ambient comfortable temperature range. The preset distance threshold can be set differently according to actual needs, for example, set to 100m, that is, when the distance between the user wearing the bracelet 300 and the indoor unit is less than 100m, the air conditioner 100 automatically enters the standby state. The preset environmental comfort temperature range can be set differently according to actual needs, for example, set to 10℃≤Tao≤20℃. Assuming that the outdoor ambient temperature Tao is 15°C, the air conditioner 100 remains in the standby state; assuming that the outdoor ambient temperature Tao is 25°C, the air conditioner 100 enters the cooling state, and the human body detection device 181 starts to obtain the blood pressure of the human wrist; assuming the outdoor ambient temperature Tao At 5°C, the air conditioner 100 enters a heating state, and the human body detection device 181 starts to obtain the blood pressure of the human wrist.

The outdoor environment temperature Tao enters the cooling/heating/maintain standby, and after entering the cooling/heating, the human body detection device 181 is used to communicate with the smart bracelet 300 to obtain the user's human wrist blood pressure, and then analyze it through the control device 200 Process relevant signals, and control the air conditioner 100 to supply air in natural wind mode or adjust the angles of the horizontal pendulum leaf 160, vertical pendulum leaf 150, fan 120, compressor 170, etc., to achieve better, more refined, and more precise The control not only saves energy, but also enhances user needs, improves user comfort experience, realizes users' high demand for intelligence, and achieves a smarter and more comfortable air supply effect.

Hereinafter, the control method of the air conditioner 100 according to the embodiment of the present invention will be described in detail by assuming that the normal diastolic pressure interval of the human wrist diastolic pressure in the cooling state is 60mmHg≤DBP<90mmHg.

When the obtained diastolic pressure of the human wrist is 60mmHg≤DBP<90mmHg, the air conditioner 100 is controlled to supply air in a natural wind mode. At this time, the horizontal swing blade 160 and the vertical swing blade 150 are controlled to be in a horizontal, horizontal and vertical limit deflection angle state, the horizontal swing blade 160 rotates substantially parallel to the horizontal plane, and the vertical swing blade 150 rotates substantially parallel to the vertical plane. If it is the first time to turn on the natural wind mode, the initial starting position of the horizontal swing leaf 160 and vertical swing leaf 150 is the horizontal vertical state; if the air conditioner 100 enters the natural wind mode during the operation, the horizontal swing leaf The positions of the

vertical swing blades

160 and 150 are adjusted to restore the horizontal and vertical state. After the third preset duration (for example, 10-15 s), the frequency of the compressor 170 is adjusted to run at a first preset frequency (for example, 36 Hz) lower than its initial frequency (for example, 56 Hz). After the fourth preset time period (for example, 30s-1min), the rotation speed of the fan 120 is adjusted to run at a first preset rotation speed (for example, 600r/min) lower than its initial rotation speed (for example, 920r/min). After the second preset period of time (for example, 1 min-1.5 min), the rotation speed of the fan 120 is adjusted intermittently, and the fan 120 is controlled to repeat multiple rotation speed adjustment cycles within the preset rotation speed interval. In each rotation speed adjustment cycle, the fan 120 The rotation speed is adjusted to a preset change rotation speed value and maintained for the first preset duration, 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 duration is, for example, 30s, and the preset variable 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 30s. It should be understood that "increase" and "decrease" herein refer to changing the trend when reaching the end value of the rotation speed range, rather than any change at any time. After the fifth preset time period (for example, 1 min-2 min), the air guide plate 113 is controlled to cover the air outlet 112 to achieve air outlet from the micro holes. Thereafter, the compressor 170 continues to operate at the first preset frequency, and the fan 120 continues to perform intermittent adjustment until the air conditioner 100 exits the natural wind mode.

When the obtained human wrist diastolic pressure is greater than or equal to 90 mmHg, the horizontal swing blade 160 and the vertical swing blade 150 are controlled to send 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, continue to obtain the diastolic pressure of the human wrist, and determine whether the diastolic pressure of the human wrist after the sixth preset period of time (for example, 5-10 min) is still ≥ 90 mmHg. If the diastolic pressure of the human wrist is greater than or equal to 90mmHg, keep the horizontal and

vertical blades

When the obtained diastolic pressure of the human wrist is less than 60mmHg, control the yaw blade 160 to deflect to the first longitudinal deflection angle and the vertical yaw blade 150 to deflect to the first lateral deflection angle, wherein the first longitudinal deflection angle is smaller than the limit deflection of the yaw blade 160 Angle, the first lateral deflection angle is smaller than the limit deflection angle of the vertical swing blade 150, and the wind deflector 113 moves out of the air outlet 112. Then, continue to obtain the diastolic pressure of the human wrist, and determine whether the diastolic pressure of the human wrist after the seventh preset period of time (for example, 5-10 min) is less than 60 mmHg. If the diastolic pressure of the human wrist is less than 60mmHg, keep the oscillating blade 160 to supply air at the first longitudinal deflection angle, and the vertical oscillating blade 150 to supply air at the first lateral deflection angle, and at the same time control the fan 120 to decelerate to the third speed lower than its initial speed. The compressor 170 runs at a preset speed (for example, 890r/min), and the compressor 170 is reduced in frequency and runs at a third preset frequency (for example, 50 Hz) lower than its initial frequency until the obtained diastolic pressure of the human wrist is in the normal diastolic pressure range. Then control the components according to the aforementioned natural wind mode.

Hereinafter, the control method of the air conditioner 100 of the embodiment of the present invention will be exemplarily described in detail with the normal diastolic pressure interval of the human wrist diastolic pressure when the heating state is set at 60mmHg≦DBP<90mmHg.

When the obtained diastolic pressure of the human wrist is 60mmHg≤DBP<90mmHg, the air conditioner 100 is controlled to supply air in a natural wind mode. At this time, the horizontal swing blade 160 and the vertical swing blade 150 are controlled to be in a horizontal, horizontal and vertical limit deflection angle state, the horizontal swing blade 160 is rotated substantially parallel to the horizontal plane, and the vertical swing blade 150 is rotated substantially parallel to the vertical plane. If it is the first time to turn on the natural wind mode, the initial starting position of the horizontal swing leaf 160 and vertical swing leaf 150 is the horizontal vertical state; if the air conditioner 100 enters the natural wind mode during the operation, the horizontal swing leaf The positions of the

vertical swing blades

160 and 150 are adjusted to restore them to the horizontal, horizontal and vertical limit deflection angle state. After the third preset duration (for example, 10-15 s), the frequency of the compressor 170 is adjusted to operate at a first preset frequency (for example, 46 Hz) lower than its initial frequency (for example, 76 Hz). After the fourth preset period of time (for example, 30 s-1 min), the rotation speed of the fan 120 is adjusted to run at a first preset rotation speed (for example, 620 r/min) lower than its initial rotation speed (for example, 960 r/min). After the second preset period of time (for example, 1 min-1.5 min), the rotation speed of the fan 120 is adjusted intermittently, and the fan 120 is controlled to repeat multiple rotation speed adjustment cycles within the preset rotation speed interval. In each rotation speed adjustment cycle, the fan 120 The rotation speed is adjusted to a preset change rotation speed value and maintained for the first preset duration, and then the next rotation speed adjustment cycle is performed. The preset rotational speed interval is, for example, 600r/min-640r/min, the first preset duration is, for example, 30s, and the preset variable rotational speed value is, for example, 20r/min, that is, the rotational speed of the fan 120 increases or decreases by 20r/min every 30s. It should be understood that the "increase" and "decrease" herein refer to changing the trend of change when the end value of the speed range is reached, rather than any change at any time. After the fifth preset time period (for example, 1 min-2 min), the air guide plate 113 is controlled to cover the air outlet 112 to achieve air outlet from the micro holes. Thereafter, the compressor 170 continues to operate at the first preset frequency, and the fan 120 continues to perform intermittent adjustment until the air conditioner 100 exits the natural wind mode.

When the obtained diastolic pressure of the human wrist is less than 60 mmHg, the horizontal swing blade 160 and the vertical swing blade 150 are controlled to send 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, continue to obtain the diastolic pressure of the human wrist, and determine whether the diastolic pressure of the human wrist after the eighth preset period of time (for example, 5-10 min) is still less than 60 mmHg. If the diastolic pressure of the human wrist is less than 60mmHg, keep the horizontal oscillating blade 160 and the vertical oscillating blade 150 continuing to supply air at the limit deflection angle, and at the same time control the fan 120 to accelerate to a second preset speed higher than its initial speed (for example, 990r/min ) To run the compressor 170 and run at a second preset frequency (for example, 81Hz) higher than its initial frequency, until the obtained diastolic pressure of the human wrist is in the normal diastolic pressure range, and then control each according to the aforementioned natural wind mode part.

Then, continue to obtain the diastolic pressure of the human wrist, and determine whether the diastolic pressure of the human wrist after the ninth preset time period (for example, 5-10 min) is still ≥90mmHg. If the diastolic pressure of the human wrist is greater than or equal to 90mmHg, keep the oscillating blade 160 to supply air at the second longitudinal deflection angle, and the vertical oscillating blade 150 to supply air at the second lateral deflection angle, and at the same time control the fan 120 to decelerate to the third lower than its initial speed. The compressor 170 runs at a preset speed (for example, 960r/min), and the compressor 170 is reduced in frequency and runs at a third preset frequency (for example, 70 Hz) lower than its initial frequency until the obtained diastolic pressure of the human wrist is in the normal diastolic pressure range. Then control the components according to the aforementioned natural wind mode.
