[0056] Figure 1 is a schematic cross-sectional view of a terminal device and an air conditioner according to an embodiment of the present invention, and Figure 2-6 The present invention provides a terminal device 1 for an air conditioner, comprising an air inlet pipe 11 and an air outlet panel 12. The air outlet panel 12 has a connecting air passage 13 inside, and a plurality of air outlet holes 14 are arranged on the lower surface of the air outlet panel 12. The air outlet holes 14 are connected to the air inlet pipe 11 via the connecting air passage 13.

[0057] Figure 1-3 In the figure, the positions of the outdoor unit and the air inlet pipe 11 are for illustration only, which does not mean that the outdoor unit must be located on the upper side of the roof. The outdoor unit can be located at any position outdoors.

[0058] Specifically, the air conditioner may be an integrated air conditioner without an air outlet surface, the air outlet of the integrated air conditioner is connected to the air inlet pipe 11, the temperature-adjusting air flow generated by the integrated air conditioner enters the air outlet panel 12 of the terminal device 1 through the air inlet pipe 11, and then blows out through the air outlet hole 14. The air conditioner may also be a split air conditioner, in which the indoor unit is not provided with an air outlet panel, but the air outlet of the indoor unit is connected to the air inlet pipe 11, the temperature-adjusting air flow generated by the indoor unit enters the air outlet panel 12 of the terminal device 1 through the air inlet pipe 11, and then blows out through the air outlet hole 14. The air conditioner may also be a central air conditioning system, a fresh air system, etc., the temperature-adjusting air flow or fresh air flow generated by it enters the air outlet panel 12 of the terminal device 1 through the air inlet pipe 11, and then blows out through the air outlet hole 14.

[0059] In this embodiment, there is no restriction on the length of the air inlet pipe 11. There can be one or more air inlet pipes 11. The air inlet pipe 11 can be arranged on the upper side of the air outlet panel 12 and connected to the connecting air duct 13, or it can be arranged on the lower side of the air outlet panel 12, or it can be clamped inside the thickness direction of the air outlet panel 12. The overall shape of the air outlet panel 12 can be square, rectangular, circular, or other shapes, which is not limited here. The lower surface of the air outlet panel 12 can be a plane or a curved surface, which can be set according to the specific home decoration style.

[0060] The air outlet panel 12 has a connecting air duct 13 inside. The connecting air duct 13 can be one, and all the air outlet holes 14 are connected to the connecting air duct 13. The connecting air duct 13 can also be multiple, and all the air outlet holes 14 are distributed in groups to multiple connecting air ducts 13. By setting the connecting air duct 13 and the air inlet pipe 11, the terminal device 1 can be set independently and separated from other components of the air conditioner, thereby simplifying the structure of the terminal device 1, reducing the thickness of the terminal device 1, reducing the space occupied, and improving the indoor aesthetics. On the other hand, since the terminal device 1 of the present application is not provided with components such as a heat exchanger and a fan, when it is set on the indoor roof 2, it can reduce noise and improve the user experience.

[0061] In some embodiments of the terminal device of the present invention, the cross-sectional area of ​​the airflow of the air inlet pipe 11 is much smaller than the cross-sectional area of ​​all the air outlet holes 14 on the lower surface of the air outlet panel 12, that is, the air outlet area is increased. For the same airflow, the airflow speed is faster at the air inlet pipe 11 and slower at the air outlet holes 14. When the air is blown out from the air outlet holes 14, even if it blows directly to the user, there will be no strong blowing feeling.

[0062] In some embodiments of the terminal device of the present invention, Figure 1 As shown, the air outlet panel 12 is used to be arranged on the lower side of the indoor roof 2. There is one air outlet panel 12, and it is configured to cover at least one half of the plane of the indoor roof 2 to form a ceiling panel.

[0063] Existing ceiling air conditioners usually need to be installed in the space between the ceiling and the indoor roof 2, and a hole is opened in the middle of the ceiling to expose the diffuser. On the one hand, since the heat exchanger, fan and diffuser of the ceiling air conditioner are integrated or arranged adjacently, the thickness of the ceiling air conditioner is relatively thick, causing the diffuser to protrude from the ceiling, or causing the overall height of the ceiling to be reduced, occupying limited indoor space. On the other hand, the diffuser and the ceiling are two different components, and it is not easy to unify the home decoration style, which affects the beauty of the home decoration. Since the terminal device 1 is separated from other components of the air conditioner, the thickness and weight of the terminal device 1 are greatly reduced, so that it does not need to be set between the ceiling and the indoor roof 2, that is, the air outlet panel 12 can be directly used as a ceiling panel. In this embodiment, in order to improve the uniformity of the home decoration style, the air outlet panel 12 is set to cover at least half of the plane of the indoor roof 2, and the remaining space can be filled with the ceiling, so that the air outlet panel 12 has a hidden installation effect, and the air outlet panel 12 will not be too abrupt in the user's vision, making it difficult for the user to distinguish between the air conditioning equipment and the architectural decoration, thereby improving the user experience. In particular, since there is only one air outlet panel 12, while the air outlet area or air outlet range is greatly increased, it is easy to select or design the shape, pattern or color of the lower surface of the air outlet panel 12 to match it with the home decoration style.

[0064] In some embodiments of the terminal device of the present invention, Figure 2 As shown, there are multiple air outlet panels 12, which are connected and have flush lower surfaces to cover the plane of the indoor roof 2 and form a ceiling panel.

[0065] In this embodiment, a plurality of air outlet panels 12 are arranged adjacent to each other. The air outlet panels 12 can be arranged so that each connecting air passage 13 is independent of each other, and the air inlet pipe 11 is provided with a plurality of outlets, which are respectively connected with each connecting air passage 13. When two air outlet panels 12 are arranged adjacent to each other, their connecting air passages 13 can also be directly connected to each other on adjacent sides, or connected through connecting pipes, so that the air inlet pipe 11 only needs to be connected to the connecting air passage of one air outlet panel 12 to blow out from the air outlet holes 14 of other adjacently arranged air outlet panels 12. When the lower surfaces of the air outlet panels 12 are all planes, the lower surfaces of all the air outlet panels 12 can be in the same plane. When the lower surfaces of the air outlet panels 12 are all curved surfaces, the highest points or lowest points of the lower surfaces of all the air outlet panels 12 are in the same plane.

[0066] In this embodiment, since the entire ceiling panel is an air outlet panel 12 and its lower surface is flush, the air outlet panel 12 can completely replace the ceiling. As a ceiling panel, on the one hand, it can achieve a unified home decoration style and improve the user's aesthetic experience. On the other hand, when using the air conditioner, it can achieve a shower-like air outlet effect throughout the house and improve the user's temperature adjustment experience.

[0067] In some embodiments of the terminal device of the present invention, there are multiple air outlet panels 12, and the lower surfaces of the multiple air outlet panels 12 are connected through the lower surface of the ceiling to cover the plane of the indoor roof 2.

[0068] In this embodiment, a plurality of air outlet panels 12 may be arranged at intervals. The air outlet panels 12 may be arranged so that each connecting air passage 13 is independent of each other, and the air inlet pipe 11 may be provided with a plurality of outlets, which are respectively connected to each connecting air passage 13. When two air outlet panels 12 are arranged at intervals, their connecting air passages 13 may also be connected through a connecting pipe, so that the air inlet pipe 11 only needs to be connected to the connecting air passage of one air outlet panel 12, and air may be blown out from the air outlet holes 14 of the other air outlet panels 12 arranged at intervals. Since the thickness of the air outlet panel 12 may be different from the thickness of the ceiling, during installation, the lower surface of the air outlet panel 12 is made flush with the lower surface of the ceiling to prevent the air outlet panel 12 from protruding from the ceiling and affecting the aesthetics of the home decoration.

[0069] In this embodiment, the ceiling panel is composed of a plurality of air outlet panels 12 and a ceiling. The shape and size of the lower surface of the air outlet panel 12 can match the ceiling. For example, the shape and size of the lower surface of the air outlet panel 12 are the same as the ceiling. The user can set the number and position of the air outlet panels 12 as needed. For example, multiple air outlet panels 12 are set in the center and around the indoor roof 2, and the other areas are set as ceilings. For another example, a ceiling is set directly above the sofa and chairs in the room, and the other areas are set as air outlet panels 12, so as to minimize or avoid users being directly under the air outlet 14.

[0070] In some embodiments of the terminal device of the present invention, there is one air outlet panel 12, and it is configured to cover the plane of the indoor roof 2 to form a ceiling panel. The air outlet panel 12 is provided with one or more through holes along the top and bottom, and the through holes are not connected to the connecting air duct 13.

[0071] In this embodiment, the air outlet panel 12 covers the entire plane of the indoor roof 2 to achieve the maximum air outlet area and air outlet range. However, the indoor roof 2 may also need to be provided with lamps, decorative parts, etc. For this reason, in this embodiment, one or more through holes are provided along the upper and lower sides of the air outlet panel 12 to facilitate embedding the lamps, decorative parts, etc. in the through holes. The through holes are not connected to the connecting air duct 13, that is, the through hole wall is closed to prevent airflow leakage in the connecting air duct 13.

[0072] In some embodiments of the terminal device of the present invention, the thickness of the air outlet panel 12 is less than 5 cm.

[0073] The overall shape of the air outlet panel 12 can be designed according to actual needs or home decoration style. For example, the air outlet panel 12 can be a flat plate as a whole, with the upper surface and the lower surface being plane and parallel, and the thickness of each region thereof being uniform. For example, the air outlet panel 12 can be wavy as a whole, that is, the upper surface and the lower surface are curved and parallel, and the thickness of each region thereof being uniform. The air outlet panel 12 can also be in other shapes as a whole, for example, the area connected to the air inlet pipe 11 is in a frustum shape, the thickness at the connection with the air inlet pipe 11 is larger, and then the thickness gradually decreases, and in other areas away from the area connected to the air inlet pipe 11, the whole is flat or wavy.

[0074] In this embodiment, the thickness of the air outlet panel 12 is the maximum thickness. Limiting the maximum thickness of the air outlet panel 12 to less than 5 cm can greatly reduce the indoor space occupied by the terminal device 1 compared to the ceiling air conditioner in the prior art. In particular, in other embodiments of the terminal device 1 of the present invention, the thickness of the air outlet panel 12 is less than 2 cm. In this way, limiting the terminal device 1 to a thickness range consistent with the ceiling can further reduce the indoor space occupied, and further enable the terminal device 1 to directly replace the ceiling, both as an air conditioning device and as a home decoration material, reducing home decoration costs and improving the unity of home decoration style.

[0075] In some embodiments of the terminal device of the present invention, Figure 1 As shown, a plurality of air outlet holes 14 are densely arranged on the lower surface of the air outlet panel 12 according to a preset rule.

[0076] A plurality of air outlet holes 14 are densely arranged on the lower surface of the air outlet panel 12, that is, the positions of the air outlet holes 14 are arranged according to the shape and size of the air outlet panel 12. When the lower surface area of ​​the air outlet panel 12 is larger, the number of air outlet holes 14 is larger and the air outlet range is wider.

[0077] In this embodiment, the preset rules can be set according to factors such as temperature control requirements, aesthetic requirements, etc. They can be simply arranged evenly, or arranged in a specific pattern, such as multiple circles, multiple rectangles, multiple five-pointed stars, or central radials.

[0078] In particular, an artistic pattern can be provided on the lower surface of the air outlet panel 12, and the shape and position of the air outlet holes 14 can be arranged according to a preset rule to match the artistic pattern. For example, the artistic pattern is a starry sky map, and the air outlet holes 14 are arranged at the stars in the map, and the shape of the air outlet holes 14 is the shape of a star. In this way, the air conditioner can be further unified with the home decoration style, achieving a hidden and traceless installation effect, and improving the beauty of the home decoration.

[0079] In some embodiments of the terminal device of the present invention, the air outlet hole 14 is a circular hole or a strip hole. The circular hole can improve the uniform air outlet effect of the air outlet panel 12. The strip hole can increase the air outlet volume of the air outlet panel 12. In other embodiments of the terminal device 1 of the present invention, the air outlet hole 14 can also be a rectangular hole, a special-shaped hole, etc., which can be set according to the temperature control requirements or aesthetic requirements. The length of the strip hole can be slightly smaller than the width of the air outlet panel 12, and a plurality of strip holes can be arranged at intervals along the length direction of the air outlet panel 12. The length of the strip hole can also be freely set, so that a plurality of strip hole arrays are densely spaced in a matrix on the entire air outlet panel 12. Of course, two or more strip holes can also cross each other, for example, in a "cross" arrangement. It should be noted that in this embodiment, the strip hole can be a flat strip hole or a strip hole along a curved surface, which can be set according to the direction of the lower surface of the air outlet panel 12. On the other hand, in this embodiment, the strip holes are not limited to oblong holes or rectangular holes. The strip holes can also be wavy holes or circular holes. As long as the length of the hole is greater than the width and the width of the hole remains unchanged throughout the entire length of the hole, it can be a strip hole.

[0080] In some embodiments of the terminal device of the present invention, the air outlet hole 14 is a special-shaped hole. The special-shaped hole can be a polygonal hole, an irregular hole, etc. By restricting the area of ​​the special-shaped hole, the air volume or air speed of a single hole can be reduced to avoid direct blowing on the user.

[0081] In particular, an artistic pattern is arranged on the lower surface of the air outlet panel 12, and the artistic pattern has corresponding graphics, such as stars, moons, flowers, etc. The position of the special-shaped hole is located at the corresponding graphics, and the shape of the special-shaped hole is consistent with the corresponding graphics. In this way, the air conditioner can be further unified with the home decoration style, achieving a hidden and traceless installation effect, and improving the beauty of home decoration.

[0082] In some embodiments of the terminal device of the present invention, the density of the air outlet holes 14 located in the middle of the air outlet panel 12 is greater than the density of the air outlet holes 14 located at the edge of the air outlet panel 12 .

[0083] In this embodiment, the density of the air outlet holes 14 is expressed as the number of air outlet holes 14 per unit area of ​​the lower surface. When the shapes and specifications of the air outlet holes 14 of the air outlet panel 12 are consistent, the greater the density, the greater the air volume, that is, the air volume in the middle of the air outlet panel 12 is larger, and the air volume at the edge is smaller, which can improve the blowing efficiency of the air outlet panel 12. In particular, when there is only one air outlet panel 12 in the room, and the air outlet panel 12 covers the entire indoor roof 2, a larger air volume can be formed in the middle of the room, and a smaller air volume can be formed at the edge of the room, which can make the temperature of the entire indoor space more uniform, or make the temperature difference between different areas of the room smaller.

[0084] In some embodiments of the terminal device of the present invention, the total area of ​​the air outlet holes 14 per unit area in the middle of the air outlet panel 12 is greater than the total area of ​​the air outlet holes 14 per unit area at the edge of the air outlet panel 12 .

[0085] When the shapes or specifications of the air outlet holes 14 are inconsistent, the air volume may not be accurately characterized by using only the density parameter. Therefore, in this embodiment, the total area of ​​the air outlet holes 14 per unit area is further used as a characteristic quantity related to the air volume, and the position arrangement of the air outlet holes 14 is associated with the total area of ​​the air outlet holes 14 per unit area, so as to further improve the uniformity of the temperature adjustment of the air outlet panel 12.

[0086] In some embodiments of the terminal device of the present invention, the density of the air outlet holes 14 located in the middle of the indoor roof 2 is greater than the density of the air outlet holes 14 located at the edge of the indoor roof 2. In this embodiment, there may be one or more air outlet panels 12. When there are multiple air outlet panels 12, the density of the air outlet holes 14 of the air outlet panel 12 located in the middle of the indoor roof 2 is greater than the density of the air outlet holes 14 at the edge of the indoor roof 2.

[0087] In some embodiments of the terminal device of the present invention, the total area of ​​the air outlet holes 14 per unit area in the middle of the indoor roof 2 is greater than the total area of ​​the air outlet holes 14 per unit area in the edge of the indoor roof 2. In this embodiment, there may be one or more air outlet panels 12. When there are multiple air outlet panels 12, the total area of ​​the air outlet holes 14 per unit area in the air outlet panels 12 located in the middle of the indoor roof 2 is greater than the total area of ​​the air outlet holes 14 per unit area in the edge of the indoor roof 2.

[0088] In some embodiments of the terminal device of the present invention, the air outlet panel 12 includes an upper panel 121 and a lower panel 122, and the air outlet holes 14 are arranged on the lower panel 122. A cavity is formed between the upper panel 121 and the lower panel 122, and the cavity is a communicating air passage 13.

[0089] In this embodiment, the upper panel 121 and the lower panel 122 can be two plates, which are fixedly connected or integrally formed. The upper panel 121 and the lower panel 122 can also be a plate with a certain thickness, and the plate has a cavity inside. It should be noted that the cavity can be one or more. Multiple cavities can be connected to each other or isolated from each other. In practical applications, the cavity can be set according to the shape and position of the air outlet 14 and the specific structure of the air inlet pipe 11.

[0090] In some embodiments of the terminal device of the present invention, the air outlet panel 12 further includes a plurality of ducts sandwiched between the upper panel 121 and the lower panel 122, and the plurality of ducts are the communicating air passages 13. In this embodiment, the plurality of ducts may be interconnected or isolated from each other.

[0091] In some embodiments of the terminal device of the present invention, a plurality of valves are arranged in the communicating air passage 13, and each valve is configured to open or close the connection between one or more air outlet holes 14 and the air inlet pipe 11. That is to say, all or part of the air outlet holes 14 of the air outlet panel 12 can be controlled by one or more valves to achieve the connection and closure with the air inlet pipe 11. In practical application, some of the air outlet holes 14 of the air outlet panel 12 can be arranged to be directly connected with the air inlet pipe 11 without passing through the valve, and these air outlet holes 14 always discharge air when the terminal device 1 is working. Other air outlet holes 14 are arranged to be connected with the air inlet pipe 11 through valves, and these air outlet holes 14 can be controlled to discharge air or not by valves when the terminal device 1 is working. Of course, all the air outlet holes 14 of the air outlet panel 12 can also be connected with the air inlet pipe 11 through valves, and when the terminal device 1 is working, the air outlet holes 14 can be controlled to discharge air or not by valves, and when the terminal device 1 is not working, all valves are closed to prevent dust and foreign matter from entering the air inlet pipe 11.

[0092] In some embodiments of the terminal device of the present invention, a valve is provided in the air inlet pipe 11. The connection and interruption of the air inlet pipe 11 are controlled by the valve.

[0093] In some embodiments of the terminal device of the present invention, the terminal device 1 further includes a plurality of air guide plates, and the air guide plates are disposed at one or more air outlet holes 14 .

[0094] In this embodiment, the air guide plate may be disposed on the outer side or the inner side of the lower surface, and may guide the airflow of the air outlet 14 , or control the opening or closing of the air outlet 14 .

[0095] In some embodiments of the air conditioner of the present invention, Figure 1-3 As shown, the air conditioner includes the above-mentioned terminal device 1. The air conditioner can be an integrated air conditioner, a split air conditioner, a central air conditioning system or a fresh air system, etc. The terminal device 1 is the terminal air outlet device of the air conditioner, which blows out the temperature-controlled airflow or fresh airflow of the air conditioner from the air outlet panel 12.

[0096] In some embodiments of the air conditioner of the present invention, Figure 1-3 As shown, the air conditioner further comprises an outdoor unit 5 and a return air duct 6. The air inlet duct 11 is connected to the air outlet of the outdoor unit 5, one end of the return air duct 6 is connected to the return air outlet of the outdoor unit, and the other end of the return air duct 6 is located in the room where the terminal device 1 is located.

[0097] In this embodiment, the outdoor unit 5 may include a heat exchanger, a fan, etc. The heat exchanger generates a temperature-controlled airflow or a fresh airflow. Under the action of the fan, the airflow is transported from the air outlet through the air inlet pipe 11 to the air outlet panel 12, and finally blown out from the air outlet 14.

[0098] In this embodiment, the inlet of the return air duct 6 can be located near the indoor roof 2, wall, floor, etc. The return air duct 6 can be one or more inlets. For example, the return air duct 6 has two inlets with opening and closing functions, one at a higher position on the wall and the other at a lower position on the wall. When the air conditioner is cooling, the inlet at a higher position is opened and the other inlet at a lower position is closed to draw away the hotter air, which is then blown out of the air outlet panel 12 after being cooled by the outdoor unit 5. When the air conditioner is heating, the air outlet panel 12 blows out air, the inlet at a lower position is opened, and the inlet at a higher position is closed to draw away the colder air, which is then blown out of the air outlet panel 12 after being heated by the outdoor unit 5.

[0099] In some embodiments of the air conditioner control method of the present invention, Figure 4 As shown, the control method includes:

[0100] S1 obtains the operating mode of the air conditioner;

[0101] S2 controls the connection state between the air outlet 14 and the air inlet duct 11 according to the operation mode; the connection state includes open and closed.

[0102] The operating mode of the air conditioner can be a temperature control mode, such as a cooling mode or a heating mode. It can also be a blowing mode, such as a strong wind mode or a breeze mode. It can also be a ventilation mode, such as a dehumidification mode, a humidification mode, or a fresh air mode. Of course, it can also be a combination of different modes. Since the air outlet panel 12 of the present application is arranged on the indoor roof 2, the air outlet area is large and the air outlet range is wide. By controlling the opening and closing states of all or part of the air outlet holes 14, it can be easily matched to the operating mode required by the user, providing the user with a good user experience.

[0103] In some embodiments of the control method of the present invention, Figure 5 As shown, the control of the connection state between the air outlet 14 and the air inlet pipe 11 includes:

[0104] S211 obtains indoor temperature and target temperature;

[0105] S212 controls the number or total area of ​​the air outlets 14 that need to be in the open state according to the absolute value of the difference between the indoor temperature and the target temperature; the number or total area of ​​the air outlets 14 that need to be in the open state is positively correlated with the absolute value of the difference.

[0106] In this embodiment, the indoor temperature is the current actual temperature, which can be the actual temperature of a preset monitoring point in the room, or the average value of the actual temperature of multiple preset monitoring points or the entire room. The target temperature is the temperature expected by the user, which can be set manually by the user, or preset or intelligently set by the air conditioner. The difference between the indoor temperature and the target temperature can be positive or negative, which corresponds to the cooling mode and the refrigeration mode respectively. When the absolute value of the difference between the indoor temperature and the target temperature is large, it means that the gap between the current actual temperature and the temperature expected by the user is large, and the temperature needs to be adjusted as soon as possible. Therefore, the control increases the number or total area of ​​the air outlets 14 that need to be in the open state to increase the air volume of the temperature-adjusting airflow and achieve rapid temperature adjustment. When the absolute value of the difference between the indoor temperature and the target temperature is small, it means that the gap between the current actual temperature and the temperature expected by the user is small, and the temperature needs to be adjusted slowly or maintained as it is. Therefore, the control reduces the number or total area of ​​the air outlets 14 that need to be in the open state to reduce the air volume of the temperature-adjusting airflow and achieve slow temperature adjustment.

[0107] In this embodiment, at a certain difference value, the number or total area of ​​the opened air outlet holes 14 can be comprehensively set according to the indoor area and the arrangement area of ​​the air outlet holes 14 to achieve an optimal ratio.

[0108] In some embodiments of the control method of the present invention, the controlling the connection state between the air outlet 14 and the air inlet pipe 11 according to the operation mode includes:

[0109] S221: In response to the operation mode being the middle air outlet mode, controlling to increase the number or total area of ​​the air outlet holes 14 in the middle of the indoor roof 2 and in the open state, and to increase the number or total area of ​​the air outlet holes 14 in the edge of the indoor roof 2 and in the closed state;

[0110] S222: In response to the operation mode being the edge air outlet mode, controlling to increase the number or total area of ​​the air outlet holes 14 in the middle of the indoor roof 2 in a closed state, and to increase the number or total area of ​​the air outlet holes 14 in the edge of the indoor roof 2 in an open state;

[0111] S223 In response to the operation mode being the local air outlet mode, all the air outlet holes 14 in the preset area are controlled to be in an open state, and all other air outlet holes 14 are controlled to be in a closed state.

[0112] In this embodiment, since the air outlet panel 12 has a large area, a large air outlet area, and many air outlet holes 14, the opening and closing area positions of the air outlet holes 14 can be controlled to control the local temperature or the global temperature of the room. The local temperature can be truly controlled and adjusted, and different temperatures can be achieved in the same room.

[0113] In some embodiments of the control method of the present invention, Figure 6As shown, the control of the connection state between the air outlet 14 and the air inlet pipe 11 according to the operation mode also includes:

[0114] S231, in response to the operating mode being the wind avoidance mode, obtaining position information of a human body indoors;

[0115] S232 controls closing the connection between one or more air outlet holes 14 directly above the human body and the air inlet pipe 11 according to the position information.

[0116] In this embodiment, the air conditioner can obtain the position information of the human body in the room at a preset time interval, or can obtain it continuously. In this way, no matter whether the human body in the room is in a stationary state or in a moving state, the opening and closing states of the corresponding air outlets 14 of the air outlet panel 12 can be fed back in time to avoid the air outlets 14 directly above the human body blowing directly on the human body. When the human body is in a moving state, the air conditioner dynamically controls the opening and closing states of different air outlets 14, closes the air outlets 14 in the area where the human body is located, and opens the air outlets 14 in the area where the human body has passed.

[0117] It should be noted that the air conditioner can obtain the position information of one or more human bodies in the room, and feed it back to the opening and closing state of the corresponding air outlet 14 of the air outlet panel 12. Of course, the air conditioner can also be set to lock a certain human body among multiple human bodies in the room and execute the wind avoidance mode for it separately. For example, if there are multiple adults and multiple children in the room, the air conditioner can execute the wind avoidance mode for multiple children separately.

[0118] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
