[0049] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0050] See also Figures 1 to 7 According to an embodiment of the present invention, an air outlet structure is provided, including: an air outlet component 1, used to deliver airflow to a target area; a sterilization module 2, used to sterilize the airflow delivered by the air outlet component 1; an air guide component 3, used to guide the flow direction of the airflow; a detection module 4, used to detect the distribution of personnel 10 in the target area, and the detection module 4 is connected to the air guide component 3 by signal to control the air guide component 3 to guide the airflow according to the distribution of personnel 10 in the target area.

[0051] Specifically, when the air outlet structure uses the sterilization module 2 for sterilization, since it is unknown whether the airflow blown by the air outlet component 1 has been sterilized, if the unsterilized air is blown toward the person 10, it will have an impact on health. With the above arrangement, when the sterilization module 2 sterilizes the airflow blown by the air outlet component 1, the detection module 4 determines whether there is a person 10 in the corresponding wind direction, and adjusts the wind direction of the air outlet component 1 to avoid the person 10 and prevent the unsterilized air from being blown toward the person 10, thus solving the technical problem in the related art that the ceiling machine causes people to inhale unsterilized air during the sterilization process.

[0052] In the air outlet structure of this embodiment, see Figure 3 The wind guide component 3 includes a wind guide plate 31, and the wind guide plate 31 is arranged at the air outlet 20 of the wind guide component 3. The wind guide plate 31 is movably arranged to guide the flow direction of the airflow.

[0053] With the above arrangement, the air guide plate 31 is moved or rotated so that the air guide plate 31 blocks the airflow, thereby effectively preventing the airflow from directly blowing onto the person 10 .

[0054] See also Figure 3 In the air outlet structure of this embodiment, the air guide component 3 includes a plurality of air outlets 20; there are a plurality of air guide plates 31, and the plurality of air guide plates 31 are arranged one-to-one corresponding to the plurality of air outlets 20 to adjust the flow direction of the airflow flowing out of each of the air outlets 20.

[0055] By adopting the above arrangement, the airflow can be controlled to move in different directions, thereby avoiding the airflow blowing in a certain direction, and ensuring the comfort of personnel 10 without affecting the sterilization blowing.

[0056] See also Figure 3 In the air outlet structure of this embodiment, the air guide plate 31 includes: a first air guide plate 311; a second air guide plate 312, which is arranged perpendicularly to the first air guide plate 311; a third air guide plate 313, which is arranged perpendicularly to the second air guide plate 312; and a fourth air guide plate 314, which is arranged perpendicularly to the third air guide plate 313.

[0057] With the above arrangement, the air guide assembly 3 can blow air in four directions, namely, forward, backward, left and right, so as to facilitate the control of the air guide plate 31 while ensuring full coverage of the air outlet angle.

[0058] The skylight machine of this embodiment, see Figure 3 , Figure 4 , including an air outlet structure, and the air outlet structure is the above-mentioned air outlet structure.

[0059] Specifically, by adding a UV lamp inside the ceiling machine and combining it with a smart eye, when it detects that the sterilization conditions are met indoors, the UV lamp turns on for disinfection. At the same time, the smart eye determines the location of the person. If someone is nearby, the air guide plate where the person is located is adjusted, the air guide plate in this direction is closed, or the anti-direct blowing mode is entered, thereby preventing people from inhaling direct blowing air while performing sterilization.

[0060] In the ceiling machine of this embodiment, see Figure 3 , Figure 4 The ceiling machine includes: a body 5, a lower portion of the body 5 having an air outlet 20; the air guide assembly 3 includes an air guide plate 31 for guiding the airflow at the air outlet 20; the detection module 4 includes a camera 41 arranged at the lower portion of the body 5.

[0061] In this way, the camera device can effectively identify whether there are people in the target area.

[0062] See also Figure 2 , Figure 3 The wind guide plate 31 includes a first wind guide plate 311, a second wind guide plate 312, a third wind guide plate 313 and a fourth wind guide plate 314. The first wind guide plate 311, the second wind guide plate 312, the third wind guide plate 313 and the fourth wind guide plate 314 form an installation space 32, and the camera 41 is located outside the installation space 32.

[0063] With the above arrangement, the detection module 4 does not occupy space on the machine body 5 , so that more devices can be arranged on the installation space 32 .

[0064] The control method of this embodiment is applicable to the above-mentioned air outlet structure, and the control method includes: judging whether the target area meets the sterilization conditions; if so, turning on the sterilization module 2 for sterilization, and the detection module 4 detecting the distribution of personnel 10 in the target area; and controlling the air guide component 3 to guide the airflow according to the distribution of personnel 10 in the target area.

[0065] With the above arrangement, when the sterilization module 2 sterilizes the airflow blown by the air outlet component 1, the detection module 4 determines whether there is a person 10 in the corresponding wind direction, and adjusts the wind direction of the air outlet component 1 to avoid the person 10 and prevent unsterilized air from being blown toward the person 10, thereby solving the technical problem in the related technology that the ceiling machine causes people to inhale unsterilized air during the sterilization process.

[0066] In the control method of this embodiment, see Figure 7According to the distribution of the personnel 10 in the target area, the method for controlling the air guide component 3 to guide the airflow includes: if the detection module 4 detects that there is no person 10 in the target area, the air guide component 3 opens the air outlet 20; if the detection module 4 detects that there is a person 10 in the target area, according to the distribution of the personnel 10 in the target area, controlling the air guide component 3 to guide the airflow.

[0067] In the control method of this embodiment, see Figure 7 The method for controlling the air guide component 3 to guide the airflow according to the distribution of the personnel 10 in the target area includes: when the wind discharged from the air outlet 20 can blow to the personnel 10 in the target area, controlling the air guide plate 31 to close the corresponding air outlet 20.

[0068] By adopting the above arrangement, it is possible to effectively prevent the airflow from directly blowing on the person 10 .

[0069] In the control method of this embodiment, see Figure 7 The method for controlling the air guide component 3 to guide the airflow according to the distribution of personnel 10 in the target area includes: setting a plurality of the air outlets 20 and a plurality of the air guide plates 31; the plurality of the air outlets 20 are set in one-to-one correspondence with the plurality of the air guide plates 31; when the air guide plates 31 are controlled to close the corresponding air outlets 20, ensuring that at least one of the air guide plates 31 opens the corresponding air outlet 20.

[0070] See also Figure 7 In the control method of this embodiment, there are four air outlets 20, and the four air outlets 20 correspond to air outlet surfaces in four different directions; when the number of the air outlets 20 that need to be closed is less than or equal to 2, the air outlets 20 that need to be closed are closed; when the number of the air outlets 20 that need to be closed is greater than 2, at least one of the air outlets 20 is opened.

[0071] With the above arrangement, the air guide assembly 3 can blow air in four directions, namely, forward, backward, left and right, so as to facilitate the control of the air guide plate 31 while ensuring full coverage of the air outlet angle.

[0072] See also Figure 7 In the control method of the present embodiment, when the number of the air outlets 20 that need to be closed is greater than 2, the method for opening at least one of the air outlets 20 includes: detecting the number of people corresponding to each air outlet surface, selecting the air outlet surface with the least number of people, and opening the air outlet surface with the least number of people; and / or, performing a detection at regular intervals to re-determine the air outlet 20 corresponding to the opened air outlet surface.

[0073] The above arrangement can ensure the normal operation of the sterilization function, and avoid direct blowing on the personnel 10 as much as possible during the normal sterilization process.

[0074] The control method of this embodiment is described as follows:

[0075] When the ceiling machine of this embodiment is sterilizing, the air guide plate 31 of the ceiling machine is facing the personnel, and the air conditioner blows directly, causing the personnel to inhale harmful air. Intelligent control technology; this system includes a UV lamp disinfection module (i.e., the sterilization module 2 of this embodiment), an air guide plate 31, an air detection module, a smart eye (equivalent to a camera 41) and a control system;

[0076] In the first stage, the system starts working: when the air detection module of the ceiling machine detects that the indoor air meets the sterilization conditions, if the smart eye detects that there is no person in the 20 directions of the air outlets on all four sides of the ceiling machine, the system controls the UV lamp to turn on, and the air conditioner will enter the anti-direct blowing mode to continue sterilization until the air detection module of the ceiling machine detects that the sterilization conditions are not met, the system controls the UV lamp to turn off, and the ceiling machine exits the sterilization mode and operates normally.

[0077] The second stage: When the ceiling machine is sterilizing with UV light, if the smart eye detects that there is someone in the direction of the ceiling machine's air outlet 20, the system controls the air guide plate 31 drive module to close the air guide plate 31 facing the person to avoid direct blowing and UV light directly hitting the person. When the smart eye detects someone: If it detects that there are people on all four sides, all air guide plates 31 are directly closed, and the sterilization control is temporarily suspended; if the smart eye detects that there are people on less than four sides in the middle, the system will control all the air guide plate 31 motors according to the smart eye detection results, close the air guide panel in the direction of the person, and the remaining directions will be discharged normally to continue sterilization. If the position of the person changes during the sterilization process, and there are people on less than four sides, the system will adjust the linkage control of all the air guide plates 31 according to the smart eye, and adjust the air guide plates 31 on the four sides to ensure that there is no air discharged in the direction.

[0078] The third stage: When the air detection module of the ceiling machine detects that the sterilization conditions are not met, the UV light is turned off and the ceiling machine exits the sterilization mode.

[0079] When the system is in the second stage of sterilization, if the smart eye detects that a person has left, the system will enter the anti-direct blowing mode to continue to maintain the room temperature, and the air conditioner will continue to sterilize until the air detection module of the ceiling unit detects that the sterilization conditions are not met. The UV light is turned off, the ceiling unit exits the sterilization mode, and enters the first stage. During this process, if the smart eye detects that a person is close to the air guide position of the air conditioner, the system will re-enter the second stage.
