The millimeter wave radar can identify very small targets and identify multiple targets at the same time.

In an embodiment, referring to <FIG> and <FIG>, the ceiling embedded-type air conditioner includes a plurality of independent deflectors, and each deflector is located in a separate outlet. Taking the center point of the ceiling embedded-type air conditioner as a center of a circle, the plurality of independent deflectors divide the blowing scope of the ceiling embedded-type air conditioner into a corresponding plurality of blowing angle ranges. Each deflector corresponds to a blowing angle range, and the complete blowing scope of each deflector can cover the corresponding blowing angle range. There are more than one deflector. It should be noted that when dividing the blowing angle ranges, the blowing scope can be averaged to be a corresponding plurality of blowing angle ranges, or can be divided in a certain rule. The specific division of the blowing scope is not limited herein.

This means each deflector can support various airflow output modes simultaneously, which include but are not limited to any one of a standard mode, a swing mode, a blow avoiding human mode, a blow toward human mode and a custom mode.

Referring to <FIG> and <FIG>, in an embodiment, the blowing to human mode means that the deflector swings with the movement of the human, to guide the airflow to human.

Referring to <FIG>, the projection distance, i. e, the perpendicular distance h, of the ceiling embedded-type air conditioner and the human on the plumb line can be determined according to the first distance d<NUM>, the first included angle β and a first formula. The first formula is h = d<NUM> * cos(β). The projection distance, i. e, the horizontal distance, of the ceiling embedded-type air conditioner and the human on the angular bisector can be determined according to the first distance d<NUM>, the first included angle β and a second formula. The second formula is d<NUM>=d<NUM>*cos(α), where d<NUM>=d<NUM>*sin(β). After the perpendicular distance h and the horizontal distance d<NUM> are determined, the target swing angle can be determined according to a third formula, θ=arctan ( d2/h ).

Operation S30, controlling the target deflector according to the target swing angle, to guide the airflow to the human.

In an embodiment, after the target swing angle of the target deflector is determined, that is, the target deflector can be controlled to the target swing angle, to guide the airflow to the human.

It can be understood that the millimeter wave human sense module may detect in real-time the position information of the human. When the human moves, the millimeter wave human sense module will obtain the first angle, the first distance and the first included angle again, then to determine a new swing angle of the target deflector according to the first angle, the first distance and the first included angle, to realize that the airflow moves with the movement of the human.

The first distance from the human to the ceiling embedded-type air conditioner is the length of the connection line from the human to the ceiling embedded-type air conditioner. The target deflector is in a blowing to human mode. A target swing angle is determined according to the first angle, the first distance and the first included angle and the target deflector is controlled to operate according to the target swing angle, to guide the airflow to the human. The position of the human is detected by the millimeter wave human sense module, and the target deflector is controlled to operate according to the target swing angle, to guide the airflow to the human, to realize the effect of the airflow moving with a movement of the human and to improve the comfort of users.

Furthermore, based on the embodiment mentioned above, in an embodiment, before the operation S10, the control method of the ceiling embedded-type air conditioner further includes:

A heartbeat signal in the target blowing angle range can be detected by the millimeter wave human sense module, and the number of the humans can be determined according to the number of heartbeat signals, or a respiration signal in the target blowing angle range can be detected by the millimeter wave human sense module, and the number of the humans can be determined according to the number of respiration signals.

In an embodiment, before the operation S11, the method further includes:
operation S12, in response to there being no humans in the target blowing angle range, controlling the target deflector to guide the airflow in a preset swing angle.

In the embodiment, the preset swing angle is previously set by a maintenance operator. At this angle, the deflector can achieve the maximum airflow output through the same fan speed. If there is no human in the target blowing angle range, it means that there is no human in the target blowing angle range, and there is no need to guide the airflow to move with the movement of the human. Therefore, the target deflector can be controlled to guide the airflow in the preset swing angle, to improve the efficiency of guiding airflow of the ceiling embedded-type air conditioner.

In an embodiment, after the operation S11, the method further includes:.

In an embodiment, in response to there being more than or equal to two humans in the target blowing angle range, the millimeter wave human sense module detects the first angle at which each human in the target blowing angle range deviates from the angular bisector of the target blowing angle range corresponding to the target deflector, the first distance from each human to the ceiling embedded-type air conditioner, the first included angle between the connection line from each human to the ceiling embedded-type air conditioner and the plumb line. Similarly to step S20, the swing angle of each human is obtained according to the position information of each human; swing angles are compared to determine a max-angle and a mini-angle of swing angles; and the target deflector is controlled to swing between the max-angle and the mini-angle to guide the airflow, to each human in the target blowing angle range, and the round-trip path of the target deflector is shortened, to shorten the round-trip time, and to avoid the airflow from being given to an unmanned area. In this way, the airflow is guided to the human as much and as fast as possible and the comfort of users is improved.

Based on the embodiment mentioned above, some embodiments of the control method of the air ceiling conditioner of the present application is provided, before the operation S10, the method further includes:.

In an embodiment, each deflector is independent. Each deflector can support different airflow output modes at the same time. The modes include but are not limited to any one of the standard mode, the swing mode, the blowing avoiding human mode, the blowing to human mode and the custom mode.

The blowing to human mode refers to that the deflector swings following the movement of humans, to guide the airflow to the human. The custom mode refers to that the deflector guides the airflow according to the angle set by the user.

Furthermore, after the operation S101, the method further includes:.

In an embodiment, the standard mode refers to that the deflector is fixed to guide the airflow in a preset swing angle, at this angle, the deflector can achieve a maximum airflow output through the same fan speed. The swing mode refers to that the deflector swings between a first limit angle and a second limit angle to guide the airflow. The limit angle is defined by a mechanical structure, so that the deflector can only swing between the first limit angle and the second limit angle. The blowing to human mode refers to that the deflector guides airflow in the first limit angle. The first limit angle is in a direction away from the human, so that a direction of guiding the airflow is away from the human.

In an embodiment, different deflectors can support different airflow output modes at the same time to meet the multiple airflow output requirements of the users.
