Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0051] In the description of this utility model, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "first feature above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "first feature above", "above" and "over" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0052] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0053] Reference Figures 1-13 As shown, the air conditioner 100 according to an embodiment of the present invention may include: a housing 10 and a supporting beam 20. The air conditioner 100 may be a cabinet-type wall-mounted air conditioner or a floor-standing air conditioner, etc.

[0054] Specifically, the housing 10 has an air outlet 11 and an air outlet duct 12. The air outlet duct 12 is connected to the air outlet 11, so that airflow can flow out from the air outlet 11 through the air outlet duct, thus meeting the airflow requirements of the air conditioner 100.

[0055] like Figure 2 , Figures 4-7 , Figures 10-13 As shown, the air outlet duct 12 has a first sidewall 121 and a second sidewall 122, the first sidewall 121 and the second sidewall 122 being along the width direction of the air outlet 11 (e.g. Figure 2 As shown in the left and right directions, the supporting beam 20 is set in the air outlet duct 12. One end of the supporting beam 20 in the length direction is connected to the first side wall 121, and the other end of the supporting beam 20 in the length direction is connected to the second side wall 122. This allows the supporting beam 20 to improve the structural strength of the air outlet duct 12, avoid deformation that would affect the air outlet effect, and help extend the service life.

[0056] In addition, if Figures 2-7 As shown, the air conditioner 100 also includes an external air guide plate 30, which is rotatably disposed at the air outlet 11, allowing the external air guide plate 30 to open or close the air outlet 11. The rotation axis of the external air guide plate 30 is along the length direction of the air outlet 11 (e.g., Figure 3 Extending in the vertical direction (as shown), the external air guide plate 30 can guide the airflow by rotating, thereby adjusting the air outlet angle on both sides of the width direction of the air outlet 11. This effectively increases the air supply range on both sides of the width direction of the air outlet 11, meeting different user needs and improving the user experience. Along the airflow direction, when the external air guide plate 30 closes the air outlet 11, it is located downstream of the supporting beam 20, ensuring a compact structure and preventing the supporting beam 20 from being exposed, thus ensuring the air conditioner 100 has a good aesthetic appearance.

[0057] At the same time, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, along the airflow direction, the end of the supporting beam 20 connected to the second side wall 122 is located upstream of the end of the supporting beam 20 connected to the first side wall 121. This replaces the disconnection of the air outlet end of the supporting beam and the second side wall in the related art with the connection of the air inlet end of the supporting beam 20 and the second side wall 122 in this invention. Therefore, when the outer guide plate 30 opens the air outlet 11, the outer guide plate 30 can rotate towards the direction close to the second side wall 122, and at least a portion of the outer guide plate 30 can be located between the second side wall 122 and the supporting beam 20. This allows at least a portion of the outer guide plate 30 to be accommodated between the second side wall 122 and the supporting beam 20, enabling the supporting beam 20 to avoid the rotation of the outer guide plate 30, ensuring reliable rotation of the outer guide plate 30. This design is simple in structure and reduces production costs.

[0058] By rotating the outer air guide plate 30 toward the direction closer to the second side wall 122, the air outlet profile of the air conditioner 100 can be changed. For example, the air outlet profile on the left side of the air outlet 11 can be changed to meet the needs of different air supply directions. At the same time, when at least a part of the outer air guide plate 30 is located between the second side wall 122 and the support beam 20, the outer air guide plate 30 can occupy the space of the air outlet duct 12, thereby reducing the space of the air outlet duct 12, which can increase the airflow velocity, effectively increase the air supply distance, and further improve the air supply range of the air conditioner 100, which is conducive to improving the user experience.

[0059] It should be noted that, for ease of description, the directions such as "up", "down", "front", "back", "left" and "right" in this utility model are based on the directional relationships shown in the accompanying drawings, and are not limitations on the directions in actual application.

[0060] In some embodiments, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the housing 10 includes a first outer shell 101 and a second outer shell 102. The first outer shell 101 and the second outer shell 102 are connected. The first housing 10 and the second housing 10 can protect the internal structure of the air conditioner 100, prevent it from being exposed and damaged, extend its service life, and have a better appearance.

[0061] In addition, if Figure 2 , Figures 4-7 , Figures 10-13 As shown, the housing 10 also includes an air outlet frame bracket 13, which is disposed inside the first housing 101 and the second housing 102. The air outlet frame bracket 13 defines an air outlet duct 12, and the first housing 10 defines an air outlet 11. This can reduce the processing complexity of the housing 10, facilitate the processing and manufacturing of the housing 10, and help reduce production costs.

[0062] According to an embodiment of the present invention, the air conditioner 100 has a supporting beam 20 connected at one end along its length to the first side wall 121 of the air outlet duct 12 and at the other end to the second side wall 122 of the air outlet duct 12. Along the airflow direction, the end of the supporting beam 20 connected to the second side wall 122 is located upstream of the end connected to the first side wall 121. The rotation axis of the outer air guide plate 30 extends along the length of the air outlet 11. Along the airflow direction, the outer air guide plate 30 is located downstream of the supporting beam 20. When the outer air guide plate 30 opens the air outlet 11, the outer air guide plate 30 faces the air outlet 11. The outer air guide plate 30 rotates near the second side wall 122 and is at least partially located between the second side wall 122 and the supporting beam 20. The rotation of the outer air guide plate 30 can guide the airflow, thereby adjusting the air outlet angle on both sides of the width direction of the air outlet 11, effectively increasing the air supply range on both sides of the width direction of the air outlet 11. The supporting beam 20 can improve the structural strength within the air outlet duct 12, while also facilitating the avoidance of the rotation of the outer air guide plate 30, ensuring the reliable rotation of the outer air guide plate 30, meeting the needs of different air supply directions, and increasing the air supply distance, which is beneficial to improving the user experience.

[0063] In some embodiments of this utility model, such as Figure 2 , Figures 4-7 As shown, the support beam 20 includes a support section 21 and a connecting section 22. The support section 21 extends along the width direction of the air outlet 11, and one end of the support section 21 in the length direction is connected to the first side wall 121, which enables the connection between the support beam 20 and the first side wall 121. The other end of the support section 21 in the length direction is spaced apart from the second side wall 122. One end of the connecting section 22 is connected to the end of the support section 21 away from the first side wall 121, and the other end of the connecting section 22 extends toward the air inlet side of the support section 21, and the other end of the connecting section 22 is connected to the second side wall 122, which enables the connection between the support beam 20 and the second side wall 122.

[0064] Meanwhile, during the process of opening the air outlet 11 of the outer air guide plate 30, at least a portion of the outer air guide plate 30 extends into the space between the connecting section 22 and the second side wall 122 through the gap between the support section 21 and the second side wall 122, which facilitates the rotation of the outer air guide plate 30 toward the direction closer to the second side wall 122 and makes it easy to store the outer air guide plate 30. The structure of the support beam 20 is simple, easy to process and manufacture, and helps to reduce production costs.

[0065] According to some embodiments of this utility model, such as Figure 2 , Figures 4-7 , Figures 10-12As shown, a receiving groove 123 is provided on the second side wall 122. The end of the connecting section 22 away from the supporting section 21 is connected to the groove wall of the receiving groove 123 away from the air outlet 11. This allows the receiving groove 123 and the supporting beam 20 to avoid interference between the second side wall 122 and the outer air guide plate 30 when the outer air guide plate 30 rotates towards the direction closer to the second side wall 122. This ensures reliable rotation of the outer air guide plate 30 and is simple in structure, making it easy to manufacture. When the air outlet 11 of the outer air guide plate 30 is opened, at least a portion of the outer air guide plate 30 is located between the connecting section 22 and the receiving groove 123 through the gap between the supporting section 21 and the second side wall 122. This facilitates the rotation of the outer air guide plate 30 towards the direction closer to the second side wall 122 and also facilitates the storage of the outer air guide plate 30.

[0066] In the embodiments of this utility model, the specific structure of the supporting beam 20 can be set according to the actual situation.

[0067] For example, in some embodiments, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the support segment 21 and the connecting segment 22 form an acute angle with each other. For example, the support segment 21 and the connecting segment 22 can be roughly formed into a V-shape to meet the required design requirements; or, the support segment 21 and the connecting segment 22 can be perpendicular to each other, for example, the support segment 21 and the connecting segment 22 can be roughly formed into an L-shape to meet the required design requirements; or, the connecting segment 22 can extend along a straight line or along a curve, for example, the connecting segment 22 extends along a curve, so that the support segment 21 and the connecting segment 22 can be roughly formed into an S-shape to meet the required design requirements. Therefore, by different designs of the support segment 21 and the connecting segment 22, different design requirements can be met, making the design more flexible.

[0068] In some embodiments of this utility model, along the length direction of the air outlet 11, the outer air guide plate 30 may include multiple (two or more) sub-air guide plates. The multiple sub-air guide plates are spaced apart along the length direction of the air outlet 11, and the multiple sub-air guide plates can rotate independently, which facilitates the individual control of the multiple sub-air guide plates. This allows the air guiding direction of the multiple sub-air guide plates to be different, so that the air supply direction of the air conditioner 100 can be adjusted more precisely, which is convenient to meet the personalized needs of different users.

[0069] In some embodiments, the multiple sub-air guide vanes can be adjusted by manual rotation or by a drive device to achieve the required adjustment, and can be set according to the actual situation.

[0070] According to some embodiments of this utility model, such as Figure 2 , Figures 4-7As shown, the outer air guide plate 30 is rotatably connected to the support beam 20, which enables the support beam 20 to support the outer air guide plate 30. This helps to improve the structural reliability of the outer air guide plate 30, avoid deformation and other problems, and thus ensure the air guiding reliability of the outer air guide plate 30.

[0071] In some embodiments of this utility model, such as Figure 2 , Figures 4-7 , Figure 14 As shown, the outer air guide plate 30 includes an air guide panel 31 and a rotating arm 32. The air guide panel 31 extends along the length direction of the air outlet 11, and the rotating arm 32 is located on one side of the thickness direction of the air guide panel 31. The rotating arm 32 is rotatably connected to the support beam 20, so that the support beam 20 can support the rotating arm 32, thereby enabling the support beam 20 to support the air guide panel 31. The rotating arm 32 facilitates the rotation of the air guide panel 31 at the air outlet 11, which helps to improve the reliability and stability of the movement of the outer air guide plate 30. At the same time, the structure of the outer air guide plate 30 is simple and easy to process and manufacture.

[0072] According to some embodiments of this utility model, such as Figure 14 As shown, there can be multiple rotating arms 32, which are spaced apart along the length of the air outlet 11. At least one rotating arm 32 is rotatably connected to the support beam 20. Multiple rotating arms 32 can support multiple different positions of the air guide panel 31, ensuring the reliability of the support of the air guide panel 31, avoiding deformation and other problems, and ensuring the reliability of air guidance.

[0073] In embodiments of this utility model, the number of rotating arms 32 can be flexibly set according to actual conditions. For example, the number of rotating arms 32 can be as follows: Figure 14 The number shown is three, but it can also be two, four, five, six or more, all of which are within the protection scope of this utility model.

[0074] In some embodiments of this utility model, such as Figure 14 As shown, the multiple rotating arms 32 include a first rotating arm 321 and a second rotating arm 322. The first rotating arm 321 is rotatably connected to the support beam 20. The air conditioner 100 also includes a first drive mechanism, which is located inside the housing 10. The housing 10 can protect the first drive mechanism from being exposed and damaged. The first drive mechanism is connected to the second rotating arm 322, so that the first drive mechanism can drive the outer air guide plate 30 to rotate through the second rotating arm 322. The first drive mechanism can provide driving force for the rotation of the outer air guide plate 30, which facilitates the automatic control of the outer air guide plate 30 and can improve the user experience.

[0075] In some embodiments, such as Figure 14As shown, the first rotating arm 321 is provided with a rotating shaft 325, which is rotatably connected to the support beam 20. This allows the first rotating arm 321 to be rotatably connected to the support beam 20 via the rotating shaft 325, thus meeting the required rotation requirements. The structure is simple and easy to manufacture.

[0076] In some embodiments, such as Figure 14 and Figure 15 As shown, the second rotating arm 322 is provided with a mounting hole 326, and the output shaft of the first drive mechanism can pass through the mounting hole 326, which can realize the connection between the first drive mechanism and the second rotating arm 322, ensure reliable connection, facilitate the rotation requirements of the outer air guide plate 30, and has a simple structure that is easy to process and manufacture.

[0077] According to some embodiments of this utility model, such as Figure 14 As shown, the plurality of rotating arms 32 also includes a third rotating arm 323, which is rotatably connected to the housing 10, allowing the housing 10 to support the air guide panel 31 via the third rotating arm 323. The third rotating arm 323 and the second rotating arm 322 are located on opposite sides of the first rotating arm 321 along the length of the air guide panel 31, respectively. Thus, the first rotating arm 321 and the third rotating arm 323 can meet the support requirements of the air guide panel 31 at two locations, and the second rotating arm 322 can meet the driving requirements of the air guide panel 31, ensuring the reliability of the support and driving of the outer air guide plate 30.

[0078] In some embodiments, such as Figure 14 As shown, the third rotating arm 323 is provided with a rotating shaft 325, which is rotatably connected to the housing 10. This allows the third rotating arm 323 to be rotatably connected to the housing 10 via the rotating shaft 325, thus meeting the required rotation requirements. The structure is simple and easy to manufacture.

[0079] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the rotating arm 32 is bent and extended to form a relief groove 324. When the outer air guide plate 30 closes the air outlet 11, at least a part of the supporting beam 20 is accommodated in the relief groove 324. The relief groove 324 can avoid the supporting beam 20, preventing the supporting beam 20 from colliding with the rotating arm 32. This makes the structure compact and can achieve the minimum and optimal rotation radius of the outer air guide plate 30, which is conducive to making full use of the space of the air outlet duct 12.

[0080] In some embodiments, such as Figure 2 , Figures 4-7As shown, the rotating arm 32 is located on one side of the air guide panel 31 in the width direction, and when the outer air guide plate 30 closes the air outlet 11, the rotating arm 32 is located on the side of the air guide panel 31 closest to the second side wall 122 (e.g. Figure 2 As shown on the left side), the opening of the clearance groove 324 faces the first side wall 121, which facilitates the rotation of the air guide panel 31 toward the direction close to the second side wall 122. The clearance groove 324 also facilitates the rotation arm 32 to avoid the support beam 20, thus avoiding interference and other problems, and ensuring that the outer air guide plate 30 rotates reliably.

[0081] According to some embodiments of this utility model, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the air conditioner 100 also includes multiple air guide blades 40 (two or more), which are spaced apart along the width direction of the air outlet 11 and extend along the length direction of the air outlet 11. Multiple support beams 20 are also spaced apart along the length direction of the air outlet 11. The multiple air guide blades 40 are rotatably mounted on the multiple support beams 20, and their rotation axis extends along the length direction of the air outlet 11. The multiple support beams 20 support the multiple air guide blades 40, ensuring reliable support at the air outlet 11. The multiple air guide blades 40 can guide the airflow, and their rotation can change the airflow direction, thus guiding the airflow from the air outlet 11 to meet user needs.

[0082] Meanwhile, with the cooperation of the air guide vane 40 and the external air guide plate 30, the air conditioner 100 can achieve different air outlet functions and effects, so as to realize different air supply states of the air conditioner 100, improve the richness of the air outlet effect of the air conditioner 100, meet the diverse needs of users, and thus improve the user's comfort and experience.

[0083] For example, in some embodiments, such as Figure 5 As shown, the air conditioner 100 has a front air supply state. When the air conditioner 100 is in the front air supply state, the outer air guide plate 30 rotates towards the direction close to the second side wall 122 and the outer air guide plate 30 is completely located between the second side wall 122 and the support beam 20. The air guide blades 40 do not rotate, so that the airflow of the air outlet duct 12 is blown out of the air outlet 11 under the guidance of the air guide blades 40, which can increase the air outlet area and increase the air outlet volume, thereby improving the air supply effect.

[0084] For example, in some embodiments, such as Figure 6As shown, the air conditioner 100 has a right-side air supply mode. When the air conditioner 100 is in the right-side air supply mode, the air outlet end of the vertical air guide plate is tilted to the right, which can guide the airflow to blow out of the air outlet 11 to the right. At the same time, the air outlet end of the outer air guide plate 30 opens the air outlet 11 and the air outlet end of the outer air guide plate 30 is tilted to the right, so that the outer air guide plate 30 can further guide the airflow to the right, which can effectively enhance the air supply effect on the right side of the air outlet 11 and increase the air supply range on the right side of the air outlet 11, so that users located on the right side of the air conditioner 100 can feel a certain breeze and meet their required air guidance needs.

[0085] For example, in some embodiments, such as Figure 6 As shown, the air conditioner 100 has a left-side air supply state. When the air conditioner 100 is in the left-side air supply state, the outer air guide plate 30 rotates towards the direction close to the second side wall 122 and the outer air guide plate 30 is completely located between the second side wall 122 and the supporting beam 20. The air outlet end of the vertical air guide plate is tilted to the left, which can guide the airflow to blow out of the air outlet 11 to the left. It can guide the airflow to flow to the left, which can effectively enhance the air supply effect on the left side of the air outlet 11 and increase the air supply range on the left side of the air outlet 11, so that the user located on the left side of the air conditioner 100 can feel a certain breeze and meet the required air supply needs.

[0086] In some embodiments where the rotating arm 32 is bent and extended to form a clearance groove 324, such as Figure 2 , Figures 4-7 As shown, when the outer air guide plate 30 closes the air outlet 11, at least a portion of the air guide blade 40 is housed in the clearance groove 324. The clearance groove 324 can avoid the air guide blade 40, preventing the rotation of the air guide blade 40 from colliding with the rotating arm 32, so that the air guide angle of the air guide blade 40 at the air outlet 11 is not affected, and the required air guide needs can be met.

[0087] In some embodiments of this utility model, a second driving mechanism is provided on one of the multiple supporting beams 20. The second driving mechanism can drive the multiple air guide blades 40 to rotate. The second driving mechanism can provide driving force for the rotation of the multiple air guide blades 40, which facilitates the automatic control of the multiple air guide blades 40, improves the user experience, ensures a compact structure, reduces space occupation, and facilitates the miniaturization design of the air conditioner 100.

[0088] According to some embodiments of this utility model, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the air conditioner 100 also includes a fan wheel 51, which is located at the end of the air outlet duct 12 away from the air outlet 11. The fan wheel 51 can drive the airflow from the air outlet duct 12 to the air outlet 11, thereby driving the airflow and ensuring reliable airflow.

[0089] In addition, if Figure 2 , Figures 4-7 As shown, the rotation axis of the outer air guide plate 30 is located between the impeller 51 and the air guide blade 40, which facilitates the rotation of the outer air guide plate 30 within the air outlet duct 12. This enables the outer air guide plate 30 to achieve the minimum and optimal rotation radius, ensuring a compact structure and reducing the space occupied.

[0090] In some embodiments, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the air conditioner 100 also includes a heat exchanger 54. In the airflow direction within the air outlet duct 12, the heat exchanger 54 is located upstream of the impeller 51. The heat exchanger 54 can exchange heat with the flowing air and drive the airflow towards the air outlet 11 via the impeller 51, thus fulfilling the user's needs. For example, it enables the air conditioner 100 to perform cooling, heating, and air delivery functions.

[0091] In some embodiments of this utility model, such as Figure 2 , Figures 4-12 As shown, the air conditioner 100 also includes multiple (two or more) louvers 52. The multiple louvers 52 are spaced apart along the length of the air outlet 11. The multiple louvers 52 are rotatably disposed at the air outlet 11. The rotation axis of the louvers 52 extends along the width of the air outlet 11. Along the airflow direction, the louvers 52 are located between the guide vane 40 and the impeller 51, so that the louvers 52 can further guide the airflow. The airflow in the air outlet duct 12 is guided by the multiple louvers 52 and then flows out through the guide vane 40, which can further improve the uniformity of the outflowing airflow, thereby better meeting the user's needs and improving the air supply effect.

[0092] At the same time, by cooperating with the louvers 52 and the air guide vanes 40, the air conditioner 100 can achieve the function and effect of air outlet 11 in different directions, which helps to achieve different air supply states of air outlet 11, improve the richness of air outlet 11 air supply effect, meet the diverse needs of users, and thus improve the user's comfort and experience.

[0093] According to some embodiments of this utility model, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the rotation axis of the outer air guide plate 30 is located between the louver 52 and the air guide blade 40, which facilitates the rotation of the outer air guide plate 30 within the air outlet duct 12. This enables the outer air guide plate 30 to achieve the minimum and optimal rotation radius, ensuring a compact structure and reducing the space occupied.

[0094] In some embodiments of this utility model, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the second sidewall 122 has a volute tongue 124, which can improve the air guiding effect of the external air guide plate 30, effectively enhance the air outlet 11 along the width direction and the air delivery range, meet the needs of users, and thus improve the user's comfort and experience.

[0095] For example, in some embodiments, such as Figure 2 , Figures 4-7 , Figures 10-12 As shown, the second sidewall 122 is located on the left side, the impeller 51 is located on the right side of the air conditioner 100 and the air outlet end of the air outlet duct 12 is tilted to the left. Due to the influence of the rotation direction of the impeller 51 and the wind-blocking effect of the volute tongue 124, the air outlet effect, air volume and air supply range when the air conditioner 100 is in the left air supply state are better than the air outlet effect, air volume and air supply range when the air conditioner 100 is in the right air supply state. Therefore, by controlling the outer air guide plate 30 to rotate towards the direction close to the second side wall 122, that is, by rotating the outer air guide plate 30 clockwise, when the air conditioner 100 is in the right air supply state, part of the outer air guide plate 30 is located between the second side wall 122 and the support beam 20. The air outlet end of the outer air guide plate 30 opens the air outlet 11 and the air outlet end of the outer air guide plate 30 is tilted to the right, so that the outer air guide plate 30 can further guide the airflow to the right, which can effectively enhance the air supply effect on the right side of the air outlet 11 and increase the air supply range on the right side of the air outlet 11.

[0096] According to some embodiments of this utility model, such as Figure 1 , Figure 2 , Figures 4-7 , Figures 10-12 As shown, the air conditioner 100 also includes a switch door 53, which is disposed on the housing 10. The switch door 53 can open or close the air outlet 11. When the switch door 53 closes the air outlet 11 and the outer air guide plate 30 closes the air outlet 11, the switch door 53 is located downstream of the outer air guide plate 30 along the airflow direction.

[0097] Therefore, when the air conditioner 100 is in the off state, the switch door 53 can close the air outlet 11, preventing external dust and other impurities from entering the air conditioner 100 through the air outlet 11, thus achieving a dustproof effect and ensuring the cleanliness of the air conditioner 100's interior. At the same time, the switch door 53 and the housing 10 together constitute the complete appearance of the air conditioner 100, enhancing its aesthetics.

[0098] In some embodiments of this utility model, such as Figures 2-7 , Figure 14 and Figure 15As shown, the outer air guide plate 30 has multiple (two or more) spaced micro-holes 33. When the airflow passes through the outer air guide plate 30, the micro-holes 33 can disperse and refine the airflow, making the airflow 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 100 and can meet the user's windless air outlet needs.

[0099] In some embodiments where a receiving groove 123 for avoiding the outer air guide plate 30 is provided on the second side wall 122, when the outer air guide plate 30 closes the air outlet 11, the space occupied by the outer air guide plate 30 in the air outlet duct 12 can be reduced, and the space of the air outlet duct 12 can be further increased by the receiving groove 123, so that when the airflow flows out of the air outlet 11 from the air outlet duct 12, the airflow dispersion range is larger, making the airflow out more gentle, ensuring good uniformity, large air volume without wind, and helping to improve the comfort of windless airflow.

[0100] For example, in some embodiments, when a user has a cooling need but does not want to be exposed to drafts, such as... Figure 4 As shown, the external air guide plate 30 rotates to the position where the air outlet 11 is closed, at which point the air conditioner 100 is in a windless air outlet state. The airflow in the air outlet duct 12 flows through the external air guide plate 30 and is then blown out of the air outlet 11. The airflow can be dispersed and formed into a diffused airflow under the action of the micro-holes 33, which can improve the turbulence state during the airflow process, and at the same time reduce the airflow velocity and improve the smoothness of the airflow. This ensures that the airflow blown out of the air outlet 11 will not blow directly towards the user, thereby achieving the windless air outlet effect of the air conditioner 100 to meet the user's needs and improve the user's comfort and experience.

[0101] Other configurations and operations of the air conditioner 100 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
