Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to an air outlet structure and an air conditioner having the same. Background Technology

[0002] In related technologies, air conditioners are generally equipped with a rotatable door at the air outlet to open or close the air outlet. However, when the door closes the air outlet, gaps are easily formed between the door and the inner wall of the air outlet, which reduces the dustproof effect of the door and affects the cleanliness of the air conditioner's interior. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an air outlet structure that prevents impurities from entering the air conditioner through the gap between the door and the air outlet frame assembly at the first air inlet end, thereby improving the dustproof effect of the door and enhancing the cleanliness inside the air conditioner.

[0004] This utility model also proposes an air conditioner, which includes the above-mentioned air outlet structure.

[0005] The air outlet structure according to an embodiment of the present invention includes: an air outlet frame assembly and a switch door. The air outlet frame assembly has an air outlet duct and an air outlet communicating with the air outlet duct. The two ends of the air outlet in the width direction are a first air outlet end and a second air outlet end, respectively. A support protrusion is provided on the inner wall of the first air outlet end. The switch door is rotatably disposed at the air outlet to open or close the air outlet. When the switch door opens the air outlet, the switch door is located within the air outlet duct. The switch door includes a door body and a door flange. When the switch door closes the air outlet, the door flange is located at the end of the door body in the width direction near the first air outlet end. Along the airflow direction, the door flange is located upstream of the support protrusion. Along the width direction of the air outlet, the door flange and the support protrusion have an overlapping area.

[0006] According to the air outlet structure of this utility model embodiment, a support protrusion is provided on the inner wall of the first air outlet end, and a door flange is provided at one end of the door body in the width direction. When the door is opened and closed to close the air outlet, the door flange is located upstream of the support protrusion along the airflow direction, and the door flange and the support protrusion have an overlapping area in the width direction of the air outlet. Thus, with the cooperation of the door flange and the support protrusion, the gap between the door and the air outlet frame assembly at the first air outlet end can be blocked, thereby ensuring the blocking effect on airflow and impurities such as dust. This prevents dust and other impurities from entering the air conditioner from the gap between the door and the air outlet frame assembly at the first air outlet end, thereby improving the dustproof effect of the door and enhancing the cleanliness inside the air conditioner. It can also improve the structural stability and aesthetic appearance of the air outlet structure and the air conditioner.

[0007] According to some embodiments of the present invention, the bracket protrusion and the door flange extend along the length direction of the air outlet.

[0008] According to some embodiments of the present invention, the door body is provided with a plurality of spaced-apart micropores.

[0009] According to some embodiments of the present invention, when the door is closed to shut off the air outlet, there is a first gap between the door flange and the bracket protrusion.

[0010] In some embodiments of this utility model, the first gap is greater than or equal to 1 mm.

[0011] According to some embodiments of the present invention, a frame protrusion is provided on the inner wall of the second air outlet end. When the door is closed, the frame protrusion is located upstream of the door body along the airflow direction, and the frame protrusion and the door body have an overlapping area along the width direction of the air outlet.

[0012] In some embodiments of this utility model, the frame protrusion extends along the length direction of the air outlet.

[0013] In some embodiments of this utility model, along the direction from the second air outlet end to the first air outlet end, the sidewall of the frame protruding on the windward side is inclined toward the outside of the air outlet.

[0014] According to some embodiments of the present invention, the side wall of the air outlet duct near the first air outlet end in the width direction has a receiving groove, and when the switch door opens the air outlet, the switch door is at least partially located in the receiving groove.

[0015] In some embodiments of this utility model, the air outlet frame assembly includes an air outlet frame and a front panel. The front panel is located on the front side of the air outlet frame and connected to the air outlet frame. The air outlet frame and the panel together define the air outlet duct and the air outlet. Part of the receiving groove is located on the air outlet frame and part is located on the front panel.

[0016] In some embodiments of this utility model, the inner wall of the receiving groove is an arc surface that bulges away from the air outlet duct.

[0017] According to some embodiments of the present invention, the air outlet ducts are two spaced apart along the width direction of the air outlet frame, the air outlets are two connected to the two air outlet ducts respectively, the two air outlets extend along the length direction of the air outlet frame and are spaced apart in the width direction of the air outlet frame, the switch doors are two corresponding to the two air outlets respectively, and the two switch doors can rotate in the direction towards each other and away from each other to open or close the air outlets.

[0018] In some embodiments of this utility model, when the two switch doors open the two air outlets respectively, the two switch doors rotate toward each other.

[0019] An air conditioner according to an embodiment of the present invention includes: the air outlet structure described above.

[0020] According to an embodiment of the present invention, the air conditioner has a bracket protrusion on the inner wall of the first air outlet and a door flange at one end of the door body in the width direction. When the door is opened and closed to close the air outlet, the door flange is positioned upstream of the bracket protrusion along the airflow direction, and the door flange and the bracket protrusion have an overlapping area in the width direction of the air outlet. Thus, with the cooperation of the door flange and the bracket protrusion, the gap between the door and the air outlet frame assembly at the first air outlet is blocked, thereby ensuring the blocking effect on airflow and impurities such as dust. This prevents dust and other impurities from entering the air conditioner from the gap between the door and the air outlet frame assembly at the first air outlet, thereby improving the dustproof effect of the door, enhancing the cleanliness inside the air conditioner, and improving the structural stability and aesthetic appearance of the air outlet structure and the air conditioner.

[0044] The air outlet structure 1001 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0045] like Figure 1 , Figure 4 and Figure 8 As shown, the air outlet structure 1001 according to an embodiment of the present utility model includes an air outlet frame assembly 100 and a switch door 300.

[0046] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, combined with Figures 7-9An air outlet structure 1001 can be installed on the air conditioner 1000 to realize the air supply function of the air conditioner 1000. The air conditioner 1000 can be a floor-standing or cabinet-type air conditioner. The air outlet frame assembly 100 has an air outlet duct 201 and an air outlet 202 communicating with the air outlet duct 201. The air outlet 202 extends along the length of the air outlet frame assembly 100. The air conditioner 1000 includes a housing 1005. The air outlet frame assembly 100 is connected to the housing 1005. The housing 1005 is cylindrical to form the overall appearance of the air conditioner 1000. The housing 1005 is provided with an air inlet 1006 communicating with the air outlet duct 201, so that airflow can enter the air conditioner 1000 from the air inlet 1006 for heat exchange, and then be blown out of the air conditioner 1000 from the air outlet 202 after passing through the air outlet duct 201, thereby realizing the air supply function of the air conditioner 1000. The air outlet frame assembly 100 and the housing 1005 are vertically arranged, meaning the air outlet 202 is along the vertical direction (see attached diagram). Figure 9 The air conditioner 1000 extends in the vertical direction (as shown), thereby expanding the air outlet range of the air conditioner 1000 in the vertical direction and ensuring the air supply effect of the air conditioner 1000.

[0047] The air outlet 202 has a first air outlet end 2021 and a second air outlet end 2022 at its two ends in the width direction. A bracket protrusion 501 is provided on the inner wall of the first air outlet end 2021. The switch door 300 is rotatably disposed at the air outlet 202 to open or close the air outlet 202. When the switch door 300 opens the air outlet 202, the switch door 300 is located in the air outlet duct 201. The switch door 300 includes a door body 51 and a door flange 53. When the switch door 300 closes the air outlet 202, the door flange 53 is located at the end of the door body 51 in the width direction near the first air outlet end 2021. Along the airflow direction, the door flange 53 is located upstream of the bracket protrusion 501. Along the width direction of the air outlet 202, the door flange 53 and the bracket protrusion 501 have an overlapping area.

[0048] It is understandable that the door 300 is rotatably located at the air outlet 202. When the air conditioner 1000 supplies air, the door 300 can rotate from the closed state toward the first air outlet end 2021 into the air outlet duct 201, thereby ensuring the airflow at the air outlet 202 and reducing air volume loss to meet the user's needs.

[0049] When the air conditioner 1000 is turned off, the switch door 300 can rotate to the position where the air outlet 202 is closed, which can prevent dust and ensure the cleanliness of the air conditioner 1000. Since the switch door 300 rotates towards the first air outlet end 2021 into the air outlet duct 201 when the air outlet 202 is opened, a gap exists between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021 to ensure the rotation of the switch door 300. When the switch door 300 closes the air outlet 202, the door flange 53 moves to the first air outlet end 2021. Thus, the door flange 53 and the bracket protrusion 501 can cooperate to block airflow and impurities such as dust, thereby reducing the possibility of air leakage and dust ingress at the gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021. Furthermore, along the airflow direction, the door flange 53 is located upstream of the bracket protrusion 501, which will not affect the rotation of the door 300 toward the air outlet 201, thus ensuring the reliability of the door 300 in opening or closing the air outlet 202.

[0050] Furthermore, along the width direction of the air outlet 202 (see attached diagram) Figure 1 and Figure 4 As shown in the dd direction, the door flange 53 and the bracket protrusion 501 have an overlapping area. Thus, along the width direction of the air outlet 202, the cooperation of the door flange 53 and the bracket protrusion 501 effectively blocks the gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021, thereby better protecting the airflow and preventing impurities such as dust from entering the air conditioner 1000 through the gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021. This improves the dustproof effect of the switch door 300 and enhances the cleanliness inside the air conditioner 1000. It also prevents the deep gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021 from being directly visible from the outside of the switch door 300, thus improving the aesthetic appearance of the air outlet structure 1001 and the air conditioner 1000.

[0051] In addition, a support protrusion 501 is provided on the inner wall of the air outlet frame assembly 100 located at the first air outlet end 2021, which can effectively enhance the structural strength of the air outlet frame assembly 100. Similarly, a door flange 53 is provided at one end of the door body 51 in the width direction, which can effectively enhance the structural strength of the door opening and closing 300, thereby enhancing the structural stability and reliability of the air outlet structure 1001 and the air conditioner 1000.

[0052] According to the air outlet structure 1001 of this utility model embodiment, a support protrusion 501 is provided on the inner wall of the first air outlet end 2021, and a door flange 53 is provided at one end of the door body 51 in the width direction. When the door 300 closes the air outlet 202, the door flange 53 is located upstream of the support protrusion 501 along the airflow direction, and the door flange 53 and the support protrusion 501 have an overlapping area in the width direction of the air outlet 202. Thus, the door flange 53 and the support protrusion 501 can be matched with each other. When closed, the door 300 and the air outlet frame assembly 100 are blocked from the gap at the first air outlet end 2021, thus ensuring the blocking effect on airflow and impurities such as dust. This prevents dust and other impurities from entering the air conditioner 1000 through the gap between the door 300 and the air outlet frame assembly 100 at the first air outlet end 2021, thereby improving the dustproof effect of the door 300, enhancing the cleanliness inside the air conditioner 1000, and also improving the structural stability and aesthetic appearance of the air outlet structure 1001 and the air conditioner 1000.

[0053] In some embodiments of this utility model, such as Figure 7 and Figure 9 As shown, the bracket protrusion 501 and the door flange 53 extend along the length of the air outlet 202. With the cooperation of the door flange 53 and the bracket protrusion 501, the gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021 is effectively blocked along the length of the air outlet 202. This provides better protection against airflow and impurities such as dust at various points along the length of the air outlet 202, preventing dust and other impurities from entering the air conditioner 1000 through the gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021. This further improves the dustproof effect of the switch door 300 and enhances the cleanliness inside the air conditioner 1000. It also prevents the deep gap between the switch door 300 and the air outlet frame assembly 100 at the first air outlet end 2021 from being directly visible from the outside, thus improving the aesthetic appearance of the air outlet structure 1001 and the air conditioner 1000.

[0054] In addition, the bracket protrusion 501 and the door flange 53 extend along the length of the air outlet 202, which can further enhance the structural strength of the air outlet frame assembly 100 and the door 300, thereby further enhancing the structural stability and reliability of the air outlet structure 1001 and the air conditioner 1000.

[0055] In some embodiments of this utility model, such as Figure 5 and Figure 6As shown, the door body 51 is provided with a plurality of spaced micro-holes 511. When the airflow flows through the door body 51 with micro-holes 511, the micro-holes 511 can disperse and refine the airflow, so that the airflow is transformed into a finer airflow. The airflow can become more uniform, delicate and gentle, which is conducive to achieving the windless air outlet effect of the air conditioner 1000 and improving the user experience.

[0056] For example, when a user needs cooling but doesn't want to be exposed to drafts, they can activate the windless mode of the air conditioner 1000. When the air conditioner 1000 is in windless mode, the door body 51 can close the air outlet 202. The airflow flows from the air outlet duct 201 inside the casing 1005 to the air outlet 202 and then passes through the door body 51 before being blown out. The airflow is dispersed by the micropores 511, forming a diffused airflow, which increases the turbulence during airflow and reduces the airflow velocity, improving the smoothness of the airflow and thus enhancing the comfort of the airflow. This prevents the airflow from blowing directly onto the user after exiting the air outlet 202, achieving the windless airflow effect of the air conditioner 1000, enriching the airflow effects of the air conditioner 1000, and ultimately meeting different user needs, improving user comfort and experience.

[0057] Furthermore, along the width direction of the air outlet 202, the door flange 53 and the bracket protrusion 501 are staggered and overlap. Thus, when the air conditioner 1000 is in a draft-free state, the cooperation of the door flange 53 and the bracket protrusion 501 along the width direction of the air outlet 202 effectively blocks the gap between the door 300 and the air outlet frame assembly 100 at the first air outlet end 2021, thereby better ensuring the obstruction of airflow and preventing air leakage from this gap. This ensures the draft-free airflow effect of the air conditioner 1000, improving user comfort and experience. The door flange 53 and the bracket protrusion 501, while reducing air leakage, also prevent condensation from forming at the first air outlet end 2021 due to air leakage, further enhancing user comfort and experience.

[0058] It should be noted that the cross-sectional shape of the micro-hole 511 can be circular, polygonal, or strip-shaped, i.e., a slit, etc., and the specific shape is not limited here. Furthermore, when multiple micro-holes 511 are provided on the door body 51, the multiple micro-holes 511 can be arranged in an array on the door body 51. This allows for the arrangement of as many micro-holes 511 as possible on the door body 51 while ensuring a certain structural strength of the door body 51. This ensures sufficient ventilation without affecting the airflow dispersion of the door body 51, thereby guaranteeing the airflow of the air outlet 202.

[0059] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, when the door 300 closes the air outlet 202, there is a first gap 531 between the door flange 53 and the bracket protrusion 501. This provides the door 300 with a certain amount of room to move, thus preventing collisions and interference between the door 300 and the bracket protrusion 501 when the door 300 rotates, ensuring the rotatability of the door 300, and consequently ensuring the stability of the door 300 when opening or closing the air outlet 202. Furthermore, the first gap 531 prevents collisions between the door flange 53 and the bracket protrusion 501 when the door 300 closes the air outlet 202, thus avoiding wear or damage. This helps ensure the structural stability and reliability of the air outlet structure 1001, and extends its service life.

[0060] In some embodiments of this utility model, the first gap 531 is greater than or equal to 1 mm. If the first gap 531 is less than 1 mm, the distance between the door flange 53 and the bracket protrusion 501 will be too small when the door 300 closes the air outlet 202. This will increase the requirements for the production and assembly precision of the door 300 and the air outlet frame assembly 100, which will easily lead to a decrease in the production and assembly efficiency of the air outlet structure 1001 and also increase the cost of the air outlet structure 1001. Therefore, making the first gap 531 greater than or equal to 1 mm can prevent the door flange 53 and the bracket protrusion 501 from colliding and interfering when the door 300 rotates, thus preventing wear or damage, thereby ensuring the rotatability of the door 300. It can also effectively reduce the production and assembly difficulty of the air outlet structure 1001, thereby ensuring the production and assembly efficiency of the air outlet structure 1001.

[0061] Of course, the first gap 531 is not necessarily better the larger it is. If the first gap 531 is too large, it will affect the shielding and sealing effect of the door flange 53 and the bracket protrusion 501 on the gap of the opening / closing door 300 and the air outlet frame assembly 100 at the first air outlet end 2021, thus failing to guarantee the blocking effect on airflow and impurities such as dust. The specific size of the first gap 531 needs to be determined according to the specific size of the air outlet structure 1001 and the specific application scenario of the air outlet structure 1001 in the air conditioner 1000. This application does not make specific limitations in this regard.

[0062] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 7 As shown, a frame protrusion 2023 is provided on the inner wall of the second air outlet end 2022. When the door 300 closes the air outlet 202, the frame protrusion 2023 is located upstream of the door body 51 along the airflow direction. Along the width direction of the air outlet 202, the frame protrusion 2023 and the door body 51 have an overlapping area.

[0063] Understandably, when the air conditioner 1000 is turned off, the switch door 300 can rotate to the position where the air outlet 202 is closed, which can prevent dust and ensure the cleanliness of the air conditioner 1000's interior. When the switch door 300 closes the air outlet 202, there is a gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022. At this time, along the airflow direction, the frame flange is located upstream of the gap between the switch door 300 and the air outlet frame assembly 100. The frame flange and the switch door 300 can cooperate to block airflow and impurities such as dust, thereby reducing the possibility of air leakage and dust ingress at the gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022.

[0064] Furthermore, along the width direction of the air outlet 202 (see attached diagram) Figure 1 and Figure 4 As shown in the dd direction, the frame flange and the door body 51 have an overlapping area. Thus, along the width direction of the air outlet 202, the frame flange can block the gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022, effectively sealing it. This better protects against airflow and impurities such as dust, preventing them from entering the air conditioner 1000 through the gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022. This improves the dustproof effect of the switch door 300 and enhances the cleanliness inside the air conditioner 1000. It also prevents the deep gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022 from being directly visible from the outside, thereby improving the aesthetic appearance of the air outlet structure 1001 and the air conditioner 1000.

[0065] In addition, a frame protrusion 2023 is provided on the inner wall of the air outlet frame assembly 100 located at the second air outlet end 2022, which can effectively enhance the structural strength of the air outlet frame assembly 100, thereby enhancing the structural stability and reliability of the air outlet structure 1001 and the air conditioner 1000.

[0066] In some embodiments of the present invention, Figure 7 and Figure 9As shown, the frame protrusion 2023 extends along the length of the air outlet 202. With the cooperation of the frame protrusion 2023 and the door body 51, the gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022 is effectively blocked along the length of the air outlet 202. This provides better protection against airflow and impurities such as dust at various points along the length of the air outlet 202, preventing dust and other impurities from entering the air conditioner 1000 through the gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022. This further improves the dustproof effect of the switch door 300 and enhances the cleanliness inside the air conditioner 1000. It also prevents the deep gap between the switch door 300 and the air outlet frame assembly 100 at the second air outlet end 2022 from being directly visible from the outside, thus improving the aesthetic appearance of the air outlet structure 1001 and the air conditioner 1000.

[0067] In addition, the frame protrusion 2023 extends along the length of the air outlet 202, which can further enhance the structural strength of the air outlet frame assembly 100, thereby further enhancing the structural stability and reliability of the air outlet structure 1001 and the air conditioner 1000.

[0068] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, along the direction from the second air vent end 2022 to the first air vent end 2021, the sidewall of the frame protrusion 2023 on the windward side is inclined towards the outside of the air outlet 202. The door 300 may be provided with multiple spaced micro-holes 511, which can disperse and refine the airflow, thus achieving a windless airflow effect for the air conditioner 1000. When a user needs cooling but does not want to be blown by the air, they can turn on the windless mode of the air conditioner 1000, close the air outlet 202 with the door 300, and the airflow flows from the air outlet duct 201 inside the housing 1005 to the air outlet 202 and then passes through the door body 51 before being blown out.

[0069] At this time, the inclined sidewall of the frame protrusion 2023 on the windward side can act as a guide, directing the airflow from the air outlet duct 201 towards the second air outlet 2022 towards the direction closer to the first air outlet 2021. This allows the airflow to exit through the micro-holes 511 of the door 300, ensuring a windless airflow effect from the air conditioner 1000 and improving user comfort and experience. The frame protrusion 2023 reduces air leakage at the second air outlet 2022 and also prevents condensation from forming on the door 300 and the air outlet frame assembly 100 at the second air outlet 2022 due to air leakage, further enhancing user comfort and experience.

[0070] In some embodiments of the present invention, Figure 1 , Figure 4and Figure 8 As shown, the side wall of the air outlet duct 201 near the first air outlet end 2021 in the width direction has a receiving groove 502. When the door 300 opens the air outlet 202, the door 300 is at least partially located within the receiving groove 502. By providing the receiving groove 502, the door 300 can move into the housing 1005 when the air outlet 202 is opened, and at least part of the door 300 can be hidden within the receiving groove 502. This effectively improves the utilization rate of the space within the housing 1005. At the same time, the receiving groove 502 provides sufficient space for the door 300 to move. The reasonable structural arrangement is conducive to improving the flexibility of the door 300's rotation.

[0071] In some embodiments of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the air outlet frame assembly 100 includes an air outlet frame 20 and a front panel 50. The front panel 50 is located on the front side of the air outlet frame 20 and is connected to the air outlet frame 20. The air outlet frame 20 and the panel together define an air outlet duct 201 and an air outlet 202. Part of the receiving groove 502 is located on the air outlet frame 20 and part is located on the front panel 50.

[0072] The front panel 50 is used to hide the complex components and connecting wires inside the air conditioner 1000 to improve the appearance. The overall structure of the front panel 50 is simpler. The bracket protrusion 501 and part of the receiving groove 502 located at the first air outlet end 2021 are located on the front panel 50, which can reduce the difficulty of processing and production, thereby helping to improve production efficiency.

[0073] Furthermore, by providing a front panel 50 on the front side of the air outlet frame 20, the size and shape of the air outlet 202 can be adjusted more flexibly, thereby facilitating the optimization of airflow distribution and improving the air delivery effect of the air conditioner 1000. When it is necessary to clean or maintain the interior of the air conditioner 1000, the front panel 50 can be removed more easily without affecting the structure and function of the air outlet frame 20, which helps to simplify the maintenance process and reduce maintenance costs.

[0074] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 8 As shown, the inner wall of the receiving groove 502 is an arc-shaped surface that protrudes away from the air outlet duct 201. The rotation trajectory of the opening and closing door 300 is arc-shaped. Therefore, setting the receiving groove 502 as an arc-shaped surface can create a larger rotation space for the opening and closing door 300, so that the inner wall of the receiving groove 502 can avoid the opening and closing door 300 when it rotates into the air outlet duct 201. This avoids collision and interference between the inner wall of the receiving groove 502 and the opening and closing door 300, and the structural arrangement is reasonable.

[0075] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, there are two air outlet ducts 201 spaced apart along the width of the air outlet frame 20, and two air outlets 202 connected to the two air outlet ducts 201 respectively. The two air outlets 202 are located along the length of the air outlet frame 20 (see attached diagram). Figure 9 Extending in the vertical direction (as shown) and in the width direction of the air outlet frame 20 (see attached diagram) Figure 8 The two air outlets 202 are spaced apart (as shown in the left-right direction). Each outlet has two doors 300 corresponding to one of the two air outlets 202. These doors 300 can rotate in directions towards and away from each other to open or close the air outlets 202. By providing two air ducts 201 and two air outlets 202, the area and air delivery range of the air outlets 202 can be effectively increased, thereby improving the air delivery effect of the air outlet structure 1001 and enhancing the user experience. Each air outlet 202 is equipped with a door 300, which serves as a dust preventer to ensure the cleanliness of the interior of the air conditioner 1000.

[0076] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, when the two doors 300 open the two air outlets 202 respectively, the two doors 300 rotate toward each other. The two first air outlet ends 2021 are respectively located at the ends of the two air outlets 202 that are closer to each other in the width direction. Therefore, the rotation of the two doors 300 toward each other to open the air outlets 202 can avoid collision between the bracket protrusions 501 and the door flanges 53 at the two first air outlet ends 2021. This ensures both the rotatability of the doors 300 and the blocking effect of the door flanges 53 and the bracket protrusions 501 on the air outlet ends 2021 against airflow or impurities.

[0077] An air conditioner 1000 according to an embodiment of the present utility model includes: the air outlet structure 1001 described above.

[0078] According to an embodiment of the present invention, the air conditioner 1000 has a support protrusion 501 on the inner wall of the first air outlet end 2021 and a door flange 53 at one end of the door body 51 in the width direction. When the door 300 closes the air outlet 202, the door flange 53 is located upstream of the support protrusion 501 along the airflow direction, and the door flange 53 and the support protrusion 501 have an overlapping area in the width direction of the air outlet 202. This allows for better coordination between the door flange 53 and the support protrusion 501. When closed, the door 300 and the air outlet frame assembly 100 are blocked from the gap at the first air outlet end 2021, thus ensuring the blocking effect on airflow and impurities such as dust. This prevents dust and other impurities from entering the air conditioner 1000 through the gap between the door 300 and the air outlet frame assembly 100 at the first air outlet end 2021, thereby improving the dustproof effect of the door 300, enhancing the cleanliness inside the air conditioner 1000, and also improving the structural stability and aesthetic appearance of the air outlet structure 1001 and the air conditioner 1000.
