Detailed Description
As shown in fig. 1, the present invention uses a ceiling-type air conditioner as a preferred embodiment, the ceiling-type air conditioner may be of an octahedral air outlet panel structure or a four-sided air outlet panel structure, wherein the middle of the panel is a grille 1, air deflectors 2 are disposed around the grille 1, a display 3 is disposed on the outer side of the grille 1 and on the inner side of the air deflector 2 in a certain direction, and an infrared sensor 4 is disposed at one corner of the panel.
The opening degree of the air deflector 2 of the ceiling type air conditioner is controlled within a reasonable range, and the opening degree is obtained by detecting the number and the position of human bodies through the infrared sensor 4. Meanwhile, the angle of the human body cannot be the same as that of the air deflector 2, so that direct blowing is avoided. The opening (angle) in the invention refers to the opening (angle) between the right lower part of the panel and the air deflector (human body), namely the angle of the human body is the included angle between the connecting line of the central point of the panel of the patio type air conditioner, which is vertical to the ground, and the connecting line of the central point of the panel and the point of the human body, which is vertically projected to the ground. The opening degree of the air deflector is an included angle between the air deflector and the right lower part of a panel of the courtyard type air conditioner.
As shown in fig. 2, under the cooling condition, when the infrared sensor does not detect a human body, the air deflectors in all directions uniformly discharge air so as to maintain uniform indoor temperature.
When the number of the detected human bodies is 1, the opening degree of the air deflector on the human side is controlled to be larger than the angle of the human bodies, namely the opening degree of the air deflector is larger than the direct blowing angle.
When the number of the detected human bodies is more than 1, judging whether the distribution of the human bodies is concentrated or not; if the concentration is carried out, the opening degree of the air deflector on the human body side is controlled to be larger than the concentrated angle (direct blowing angle) of the human body, similar to the case that the number of people is 1; if not, controlling the opening of the air deflectors at different directions and on the human sides to be larger than the angle of the human body farthest away from the air deflectors;
therefore, the air guide plate is controlled to supply air to the outside in the cold air downstream, and the uncomfortable feeling of direct blowing or downward blowing is avoided.
As shown in fig. 3, in the heating condition, when the infrared sensor does not detect a human body, the air deflectors in all directions uniformly discharge air so as to maintain uniform indoor temperature.
When the number of the detected human bodies is 1, the opening degree of the air deflector on the human side is controlled to be smaller than the angle of the human bodies, namely the opening degree of the air deflector is smaller than the direct blowing angle.
When the number of the detected human bodies is more than 1, judging whether the distribution of the human bodies is concentrated or not; if the concentration is carried out, the opening degree of the air deflector on the human body side is controlled to be smaller than the angle of the human body, namely, the angle of the direct blowing, similarly to the case that the number of people is 1. If not, the opening degree of the human-side air deflector in different directions is controlled to be smaller than the angle of the human body nearest to the air deflector.
Therefore, the air guide plate is controlled to blow air downwards at the hot air upstream, so that the discomfort of direct blowing is avoided, or the heat utilization rate caused by upward blowing is low.
When a human body is detected, the control mode is the same for all the air deflectors, but the opening degree of each air deflector is controlled in different directions according to the detected human body condition according to different air outlet directions of each air deflector.
Besides the patio type air conditioner, the air conditioner adopting the control method of the air deflector also belongs to the protection scope of the invention.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
