[0045] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0046] like Figure 1-Figure 3 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 1, a perforated plate 2, and a switch door 3.

[0047] Specifically, such as Figure 1-Figure 3 As shown, the housing 1 includes a housing body 13 and an air outlet frame 14. Figure 1In the example shown, the air conditioner 100 is a vertical air conditioner. The housing body 13 includes a chassis 131, a front housing 132, a rear housing 133, and a top cover 134. The front housing 132 and the rear housing 133 are both located on the chassis 131 and connected to the chassis 131. The front housing 132 is located in front of the rear housing 133 and connected to the rear housing 133. The top cover 134 is located above the front housing 132 and the rear housing 133 and is connected to both the front housing 132 and the rear housing 133. The chassis 131, the front housing 132, the rear housing 133, and the top cover 134 together define the installation space. The rear housing 133 is provided with an air inlet 19, the front housing 132 is provided with an air outlet 11, the air outlet frame 14 is located inside the housing 1, the air outlet frame 14 has an air outlet duct 141, the air outlet duct 141 has an inlet 143 and an outlet 144, the inlet 143 is connected to the air inlet 19, and the outlet 144 is connected to the air outlet 11.

[0048] like Figure 3 As shown, the shell body 13 also includes a fan assembly and a heat exchanger 8. The heat exchanger 8 is positioned opposite the air inlet 19. Along the airflow direction, the fan 9 is located between the heat exchanger 8 and the air outlet frame 14. The fan 9 drives the airflow from the air inlet 19 to the air outlet duct 141, and then to the air outlet 11. The heat exchanger 8 is used for heat exchange. It can exchange heat with the airflow entering the shell body 13. The heat-exchanged airflow flows from the air outlet 11 into the room, thus realizing the cooling or heating function of the air conditioner 100.

[0049] The fan assembly may include a fan 9 and a drive assembly for driving the fan 9 to rotate. The fan 9 may be a cross-flow fan 9, and the drive assembly may include a drive motor 231. The motor shaft of the drive motor 231 is connected to the fan 9 for driving the fan 9 to rotate. Of course, this utility model is not limited to this; the fan 9 may also be a centrifugal fan or an axial fan, etc.

[0050] refer to Figure 1-Figure 3 As shown, the housing 1 has an air outlet 11, which can be specifically located on the housing body 13. The air outlet 11 has a first air outlet area 111, which extends along the length of the housing 1, and the first air outlet area 111 also extends along the length of the housing 1. For example, in Figure 1 and Figure 2 In the example shown, both the air outlet 11 and the first air outlet area 111 extend in the vertical direction.

[0051] like Figure 2 and Figure 3As shown, the perforated plate 2 is movably disposed on the housing 1 to open or close the first air outlet zone 111. For example, the perforated plate 2 can move in the width direction of the air outlet 11 to open or close the first air outlet zone 111. For example, the perforated plate 2 can rotate relative to the housing 1, or the perforated plate 2 can move relative to the housing 1 along the width direction of the air outlet 111. The perforated plate 2 has a plurality of spaced ventilation holes 21. When the perforated plate 2 opens the first air outlet zone 111, the airflow in the air outlet duct 141 can be directly discharged into the room through the first air outlet zone 111. Due to the absence of obstruction by the perforated plate 2, the airflow velocity is relatively high, resulting in higher cooling and heating efficiency. When the perforated plate 2 closes the first air outlet zone 111, the airflow in the air outlet duct 141 can be discharged into the room through the ventilation holes 21 on the perforated plate 2. During the process of flowing out of the first air outlet zone 111, due to the obstruction by the perforated plate 2 and the dispersion by the ventilation holes 21 on the perforated plate 2, the airflow velocity is reduced and the airflow is dispersed, achieving a windless effect.

[0052] In addition, since the perforated plate 2 is a large plate structure, the number of ventilation holes 21 provided on the perforated plate 2 is relatively larger than the number of ventilation holes 21 provided on the air guide plate 5 and louvers 61, which can increase the air outlet area, increase the air volume in the windless mode, and improve the cooling and heating effect.

[0053] In addition, there are multiple perforated plates 2 spaced apart along the length of the first air outlet zone 111. Multiple perforated plates 2 can be configured to provide different windless modes according to user needs. It is understood that when all perforated plates 2 are closed in the first air outlet zone 111, a completely windless mode can be achieved; when some perforated plates 2 are open in the first air outlet zone 111 and some are closed, a localized windless mode can be achieved.

[0054] For example, in Figure 2 In the example shown, the orifice plate 2 is along the length direction of the first air outlet zone 111 (e.g., Figure 2 The two perforated plates (shown in the vertical direction) are spaced apart. When both perforated plates 2 are closed in the first air outlet zone 111, a completely windless mode can be achieved. When the upper perforated plate 2 is open in the first air outlet zone 111 and the lower perforated plate 2 is closed in the first air outlet zone 111, a windless mode can be achieved. Figure 5 As shown, when the upper perforated plate 2 closes the first air outlet zone 111 and the lower perforated plate 2 opens the first air outlet zone 111, a windless mode can be achieved to meet different user needs.

[0055] like Figure 1-Figure 3As shown, the switch door 3 is movably mounted on the housing 1 and is used to open or close the air outlet 11. When the switch door 3 closes the air outlet 11 and the perforated plate 2 closes the first air outlet zone 111, the switch door 3 is located downstream of the perforated plate 2 along the airflow direction. In the off state of the air conditioner 100, the switch door 3 can close the air outlet 11, preventing external dust and other contaminants from entering the interior of the air conditioner 100 through the air outlet 11, thus achieving the effect of preventing insects and dust. In addition, the switch door 3 can also conceal the internal structure of the air outlet 11, improving the aesthetics of the air conditioner 100.

[0056] The switch door 3 can move in the width direction of the air outlet 11 to open or close the air outlet 11, or the switch door 3 can rotate relative to the housing 1 to open or close the air outlet 11. When the switch door 3 opens the air outlet 11, the switch door 3 can be located on one side in the width direction of the air outlet 11. In addition, when the switch door 3 opens the air outlet 11, the switch 3 can be located on the outside or inside of the housing 1.

[0057] According to an embodiment of the present invention, the air conditioner 100 has a perforated plate 2 with ventilation holes 21 at the first air outlet area 111 of the air outlet 11. The perforated plate 2 is used to open or close the air outlet 11. When the perforated plate 2 closes the air outlet 11, the air conditioner 100 can achieve a windless mode, with a large air outlet area, large air volume, and good cooling or heating effect. In addition, multiple perforated plates 2 are arranged along the length of the first air outlet area 111 to achieve different windless modes, meet different user needs, and improve the user experience.

[0058] In some embodiments of the present invention, Figure 10 and Figure 11 As shown, the air conditioner 100 also includes a plate drive mechanism 23, which is located inside the housing 1 and is used to drive the perforated plate 2 to move. This automates the movement of the perforated plate 2, making it easier for users to operate and improving their experience. Specifically, as shown... Figure 10 and Figure 11 As shown, the plate drive mechanism 23 is mounted on the air outlet frame 14 and located between the air outlet frame 14 and the shell body 13.

[0059] Furthermore, such as Figure 7 and Figure 10 As shown, there are multiple plate drive mechanisms 23 spaced apart along the length of the first air outlet zone 111, and each plate drive mechanism 23 corresponds to one of the multiple perforated plates 2. It can be understood that each perforated plate 2 corresponds to one plate drive mechanism 23, and each perforated plate 2 is driven by one plate drive mechanism 23.

[0060] For example, in Figure 7 and Figure 10In the example shown, the plate drive mechanism 23 corresponding to the perforated plate 2 is spaced apart from the two ends of the corresponding perforated plate 2 along the length direction of the first air outlet area 111, and is located in the middle area of ​​the corresponding perforated plate 2 along the length direction of the first air outlet area 111. This can improve the reliability of the plate drive mechanism 23 in driving the perforated plate 2 to move, and ensure the consistency of the movement of the perforated plate 2 along the length direction of the first air outlet area 111.

[0061] In some embodiments of this utility model, such as Figure 4 , Figure 6 Figure 11 and Figure 12 As shown, the perforated plate 2 is movably mounted on the housing 1. Specifically, the perforated plate 2 can move along the width direction of the air outlet 11 or the circumferential direction of the housing 1. The inner surface of the perforated plate 2 has a rack 22 extending along the width direction of the perforated plate 2. The plate driving mechanism 23 includes a drive motor 231, which is mounted on the housing 1. The input gear 2321 of the gear assembly 232 is connected to the motor shaft of the drive motor 231, and the output gear 2322 of the gear assembly 232 meshes with the rack 22. When the drive motor 231 rotates, it drives the gear assembly 232 to rotate. The gear assembly 232, through meshing with the rack 22, drives the rack 22 to move, thereby driving the perforated plate 2 to move, thus opening or closing the first air outlet zone 111.

[0062] The gear assembly 232 may include one or more gears. When the gear assembly 232 includes one gear, the input gear 2321 and the output gear 2322 of the gear assembly 232 are the same gear. When the gear assembly 232 includes multiple gears, the input gear 2321 and the output gear 2322 are two different gears.

[0063] For example, in Figure 4 and Figure 6 In the example shown, the gear assembly 232 includes three gears: an input gear 2321, an output gear 2322, and an intermediate gear 2323. The input gear 2321 is connected to the output shaft of the drive motor 231, the output gear 2322 meshes with the rack 22, and the intermediate gear 2323 meshes with both the input gear 2321 and the output gear 2322. The axes of the input gear 2321, the intermediate gear 2323, and the output gear 2322 are in the same direction and are spaced apart in the same plane perpendicular to the length direction of the first air outlet zone 111.

[0064] Optionally, the rack 22 and the perforated plate 2 can be separate parts or a single piece. When the rack 22 and the perforated plate 2 are a single piece, they can be integrally injection molded, simplifying the assembly process between them. When the rack 22 and the perforated plate 2 are separate parts, they can be processed independently, for example, by independent injection molding. After the rack 22 and the perforated plate 2 are processed separately, they are then connected together. The rack 22 and the perforated plate 2 can be connected by fasteners or snap-fit ​​connections. This simplifies the structure of the rack 22 and the perforated plate 2 and improves production efficiency.

[0065] In some embodiments of the present invention, Figure 7 , Figures 9-13 As shown, the plate drive mechanism 23 also includes a gear box 233, which is disposed on the housing 1. Specifically, the gear box 233 is disposed on and connected to the air outlet frame 14. At least a portion of the gear assembly 232 is located inside the gear box 233. It is understood that at least a portion of the output gear 2322 is exposed outside the gear box 233 for meshing with the rack 22, while the other portion may be located inside the gear box 233. The drive motor 231 is located outside the gear box 233 and is connected to at least one of the gear box 233 and the air outlet frame 14. It is understood that the drive motor 231 may be located outside the gear box 233, or the drive motor 231 may be connected only to the gear box 233, or the drive motor 231 may be connected only to the air outlet frame 14, or the drive motor 231 may be connected to both the gear box 233 and the air outlet frame 14.

[0066] For example, in Figure 11 In the example shown, the drive motor 231 is located on one side of the gearbox 233 along the axial direction of the input gear 2321 and the output gear 2322.

[0067] like Figure 7 , Figures 9-13 As shown, the gearbox 233 is provided with a first guide member 2331. A first guide groove 221 extending along the width direction of the perforated plate 2 is defined between the rack 22 and the perforated plate 2. The first guide member 2331 is movably disposed within the first guide groove 221. Thus, the movement trajectory of the rack 22 can be limited by the limiting relationship between the first guide member 2331 and the first guide groove 221, thereby limiting the movement trajectory of the perforated plate 2 and ensuring the reliability of the perforated plate 2 in opening or closing the air outlet 11.

[0068] Optionally, such as Figure 11As shown, the first guide member 2331 is a plate-like structure extending along the moving trajectory of the rack 22, which ensures the correctness of the moving trajectory of the rack 22, thereby ensuring the correctness of the moving trajectory of the perforated plate 2. Of course, this utility model is not limited to this; the first guide member 2331 can also be multiple guide posts or guide blocks spaced apart along the moving direction or moving trajectory of the rack 22.

[0069] Furthermore, if Figure 7 , Figures 9-13 As shown, there are two first guide grooves 221, located on opposite sides of the rack 22 in the width direction. The openings of the two first guide grooves 221 face opposite directions and face opposite sides of the orifice plate 2 in the length direction. There are also two first guide members 2331, spaced apart along the length of the first air outlet area 111 and located within the two first guide grooves 221. The output gear 2322 is located between the two first guide members 2331. This not only improves the guiding effect on the rack 22 but also enables the connection between the orifice plate 2 with the rack 22 and the drive assembly, thereby achieving the connection between the orifice plate 2 and the air outlet frame 14 and ensuring the reliability of the orifice plate 2's operation.

[0070] Specifically, such as Figure 12 and Figure 13 As shown, the rack 22 includes a body portion 222 and a flange portion 223. The body portion 222 extends along the width direction of the perforated plate 2 and is fitted and connected to the perforated plate 2. A plurality of teeth are spaced apart along the length direction of the body portion 222 on the side of the body portion 222 facing away from the perforated plate 2. Flange portions 223 are provided on both sides of the body portion 222 along the length direction of the perforated plate 2. The flange portions 223 extend along the width direction of the perforated plate 2 and are spaced apart from the perforated plate 2, defining a first guide groove 221 with its opening facing the side of the perforated plate 2 along its length direction. Figure 10 and Figure 11 As shown, the first guide member 2331 includes a connecting part 2332 and a guide part 2333. One end of the connecting part 2332 is connected to the gear box 233, and one end of the guide part 2333 is connected to the other end of the connecting part 2332. The guide parts 2333 of the two first guide members 2331 extend away from the end of the connecting part 2332 and move towards each other. The two guide parts 2333 are respectively located in the two first guide grooves 221.

[0071] During the assembly of the air conditioner 100, one end of the length direction of the two first guide grooves 221 on the inner side of the perforated plate 2 can be aligned with the two first guide members 2331 respectively. Then, the perforated plate 2 is moved to fit the two guide parts 2333 of the two first guide members 2331 into the two first guide grooves 221 respectively.

[0072] In some embodiments of this utility model, such as Figure 10 and Figure 12 As shown, the perforated plate 2 is movably mounted on the housing 1 along the circumferential direction. Second guide members 24 are provided at both ends of the perforated plate 2 along the length of the first air outlet area 111. A slide rail 15 is provided on the housing 1, and a second guide groove 151 is provided on the slide rail 15, extending along the circumferential direction of the housing 1. Multiple slide rails 15 are spaced apart along the length of the first air outlet area 111. The second guide members 24 at both ends of the length of each perforated plate 2 are respectively located within a second guide groove 151. This allows for limiting and guiding the perforated plate 2 at both ends along its length, ensuring the reliability of the perforated plate 2's movement and the reliability of opening or closing the air outlet 11.

[0073] Optionally, such as Figure 13 As shown, the second guide member 24 is formed as a guide post or guide block, and multiple second guide members 24 at the same end along the length direction of the first air outlet area 111 of the perforated plate 2 are spaced apart along the width direction of the perforated plate 2. This can improve the reliability of the movement of the perforated plate 2 and ensure the reliability of the opening or closing of the air outlet 11 of the perforated plate 2.

[0074] exist Figure 13 In the example shown, one end of the perforated plate 2 in the length direction has a plurality of second guide members 24, wherein at the same end in the length direction of the perforated plate 2, a second guide member 24 is provided at both ends in the width direction of the perforated plate 2, and a plurality of spaced second guide members 24 are provided in the middle region in the width direction of the perforated plate 2.

[0075] In some embodiments of this utility model, the slide rail 15 is either a separate component from the housing 1 or partly integral with the housing 1. For example, in Figure 10 In the example shown, the slide rail 15 is mounted on the air outlet frame 14. The slide rail 15 and the air outlet frame 14 can be separate parts or a single piece. When the slide rail 15 and the air outlet frame 14 are separate parts, they can be processed independently. The processed slide rail 15 and the air outlet frame 14 are then connected together, for example, by snap-fit ​​or by fasteners. This simplifies the structure of the slide rail 15 and the air outlet frame 14 and improves production efficiency. When the slide rail 15 and the air outlet frame 14 are a single piece, they can be integrally injection molded, which simplifies the assembly process between the slide rail 15 and the air outlet frame 14.

[0076] In some embodiments of the present invention, Figure 7 and Figure 10As shown, a crossbeam 16 is provided inside the air outlet 11. The crossbeam 16 is spaced apart from both ends of the air outlet 11 along its length. The two ends of the crossbeam 16 along its length are connected to the two ends of the air outlet 11 along its width. A crossbeam 16 is provided between two adjacent perforated plates 2. Two slide rails 15, which cooperate with the second guide members 24 at the ends of the two adjacent perforated plates 2 that are close to each other, are located on the crossbeam 16. This facilitates the guidance and limiting of the ends of the two adjacent slide rails 15 that are close to each other, improving the reliability of the movement of the perforated plates 2.

[0077] For example, in Figure 7 and Figure 10 In the example shown, the orifice plate 2 is along the length of the first air outlet zone 111, i.e. Figure 7 The two air outlet zones 111 shown are spaced apart in the vertical direction. The first air outlet zone 111 has a crossbeam 16 located between two perforated plates 2. Each perforated plate 2 has a second guide 24 at both ends along the length of the air outlet 11. A slide rail 15 is provided on the air outlet frame 14 below the air outlet 11. The second guide 24 located below the lower perforated plate 2 is located in the second guide groove 151 of the slide rail 15 below the air outlet 11. A slide rail 15 is provided on the upper and lower sides of the crossbeam 16. The second guide 24 located at the upper end of the lower perforated plate 2 is located in the second guide groove 151 of the slide rail 15 below the crossbeam 16. The second guide 24 located at the lower end of the upper perforated plate 2 is located in the second guide groove 151 of the slide rail 15 above the crossbeam 16.

[0078] In some embodiments of the present invention, Figure 12 and Figure 13 As shown, the edge of the perforated plate 2 is provided with a flange 25, which is folded towards the inside of the perforated plate 2. The flange 25 can extend along the length of the edge of the perforated plate 2, thereby improving the structural strength of the perforated plate 2, thereby improving the deformation resistance of the perforated plate 2 and improving the reliability of the perforated plate 2 in opening or closing the first air outlet zone 111.

[0079] Furthermore, such as Figure 13 As shown, the flange 25 has a notch at a position opposite to the first guide groove 221, which facilitates the first guide member 2331 on the gear box 233 to be inserted into the first guide groove 221.

[0080] In some embodiments of the present invention, Figure 4 and Figure 6As shown, the housing 1 has a first cavity 12, which is located on one side of the air outlet 11 in the width direction and communicates with the air outlet 11. When the perforated plate 2 and the switch door 3 open the air outlet 11, the perforated plate 2 and the switch door 3 are located inside the first cavity 12. It can be understood that when the air conditioner 100 is a vertical air conditioner, the air outlet 11 extends in the vertical direction, the length direction of the air outlet 11 is vertical, the air outlet 11 is located on the front side of the housing 1, and the width direction of the air outlet 11 is horizontal. The first cavity 12 can be located on the left side of the air outlet 11, and the right side of the first cavity 12 is open and communicates with the air outlet 11, or the first cavity 12 can be located on the right side of the air outlet 11, and the left side of the first cavity 12 is open and communicates with the air outlet 11.

[0081] exist Figure 4 In the example shown, the first cavity 12 is located to the right of the air outlet 11, and the left side of the first cavity 12 is open and connected to the air outlet 11.

[0082] The first cavity 12 may be located between the shell body 13 and the air outlet frame 14, and is defined by the shell 1 and the air outlet frame 14, or the first cavity 12 may be located inside the air outlet frame 14.

[0083] When the perforated plate 2 opens the first air outlet zone 111, the perforated plate 2 is located inside the first cavity 12. The first cavity 12 is located on one side of the width direction of the air outlet duct 141 and is spaced apart from the air outlet duct 141. This can prevent the perforated plate 2 from being located inside the duct when the air outlet 11 is opened, thus avoiding affecting the airflow. It can ensure the smooth flow of air in the air outlet duct 141, reduce the resistance of airflow, and reduce the noise generated by the airflow.

[0084] When the air outlet 11 is opened by the switch door 3, the switch door 3 is located in the first cavity 12 and on the side of the perforated plate 2 away from the center of the housing 1. The switch door 3 and the perforated plate 2 are both located in the first cavity 12. This not only allows the switch door 3 to be located inside the housing 1, ensuring the appearance of the air conditioner 100, but also allows the switch door 3 and the perforated plate 2 to share the same first cavity 12, simplifying the structure and processing technology of the housing 1, making full use of the receiving cavity on the right side of the air outlet 11, and making the structure more compact.

[0085] Of course, this utility model is not limited to this. A second cavity is also provided inside the housing 1. The second cavity is located on the side of the air outlet 11 away from the first cavity 12 in the width direction and is connected to the air outlet 11. When the door 3 opens the air outlet 11, the door 3 is located inside the second cavity. The first cavity 12 and the second cavity can be symmetrically arranged. This ensures that the structural strength on both sides of the air outlet 11 in the width direction is approximately the same, guaranteeing the reliability of the air conditioner 100.

[0086] In some embodiments of the present invention, Figure 5 , Figure 7and Figure 8 As shown, the air outlet 11 extends vertically and includes a second air outlet area 112. The first air outlet area 111 is located below the second air outlet area 112. The second air outlet area 112 has a jetting plate 1121, which is connected to the housing 1 at both ends along the width of the air outlet 11 to guide the airflow in the second air outlet area 112 upward. This guides the airflow above the air outlet 11 upward, preventing it from blowing directly at the user and further achieving a windless mode.

[0087] The air jetting plate 1121 can be fixed on the housing 1. Along the airflow direction, the air jetting plate 1121 is inclined upward. The air jetting plate 1121 can also be rotatably mounted on the housing 1.

[0088] When the air conditioner 100 is in the draftless mode, the airflow in the first air outlet zone 111 can flow out through the ventilation holes 21 on the perforated plate 2, achieving a draftless feel. The airflow in the second air outlet zone 112 can be guided upward by the air throw plate 1121, preventing the airflow in the second air outlet zone 112 from blowing directly on the user, thus achieving the draftless mode. In addition, the second air outlet zone 112 is not obstructed by the perforated plate 2, thereby increasing the air volume in the draftless mode, greatly improving the temperature uniformity in the room, reducing the temperature difference in different parts of the room, and improving the comfort of the draftless mode.

[0089] In addition, such as Figure 5 , Figure 7 and Figure 8 As shown, a dividing rib 18 is provided between the first air outlet zone 111 and the second air outlet zone 112. A slide rail 15 may be provided on the dividing rib 18. The second guide member 24 at the upper end of the perforated plate 2 located on the upper side of the crossbeam 16 may be provided in the second guide groove 151 of the slide rail 15 on the dividing rib 18.

[0090] In some embodiments of this utility model, the air conditioner 100 further includes a door drive mechanism 31, which is disposed inside the housing 1. There are two door drive mechanisms 31, which are respectively disposed on both sides of the air outlet 11 along the length direction, and are used to drive the two ends of the door 3 along the length direction to move.

[0091] In some embodiments of this utility model, such as Figure 5As shown, the crossbeam 16 has guide plates 5 on both sides along the length of the air outlet 11. Multiple guide plates 5 are spaced apart along the width of the air outlet 11. The guide plates 5 are rotatably mounted at the air outlet 11, located upstream of the perforated plate 2 along the airflow direction. The crossbeam 16 has shaft holes on both sides along the length of the air outlet 11 that mate with the guide plates 5. This facilitates fixing the guide plates 5 on both sides of the crossbeam 16 along the length of the air outlet 11. The rotation axis of the guide plates 5 extends along the length of the air outlet 11, allowing the guide plates 5 to guide airflow in the width direction of the air outlet 11, thus achieving air delivery at different angles.

[0092] In some embodiments of the present invention, Figure 5 As shown, the crossbeam 16 can also be provided with fixing ribs 17 on both sides along the length direction of the air outlet 11. The fixing ribs 17 extend along the width direction of the air outlet 11 and the two ends of the length direction are connected to the two ends of the air outlet 11 opposite to the width direction of the air outlet 11. The fixing ribs 17 and the two ends of the length direction of the air outlet 11 are spaced apart from the crossbeam 16. The air guide plate 5 is rotatably mounted on the fixing ribs 17, thereby improving the reliability of fixing the air guide plate 5.

[0093] In some embodiments of the present invention, Figure 4 As shown, the air conditioner 100 also includes a louver assembly, which includes multiple louvers 61 and a connecting rod. The multiple louvers 61 are spaced apart along the length of the air outlet 11. The louvers 61 are rotatably connected to the inner wall of the air outlet duct 141. The connecting rod is rotatably connected to the multiple louvers 61 and extends along the length of the air outlet 11. Along the airflow direction, the louver assembly is located upstream of the air guide plate 5, and the louvers 61 can guide the airflow along the length of the air outlet 11.

[0094] The air conditioner 100 according to the present utility model has the characteristics of low cost, simple and compact structure, good comfort, large air volume without wind, and good uniformity.
