Examples of the embodiments are shown in the accompanying drawings, where 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 by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0054] An air conditioner 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0055] Referring Figure 1 and Figure 4 , the air conditioner 1000 according to an embodiment of the present invention includes: an air duct member 200 and a wind guiding assembly 100. Specifically, the air duct member 200 defines an air outlet duct 201, and one end of the air outlet duct 201 is formed as an air outlet 202. Thus, after the outside air is adjusted by the air conditioner 1000, it can pass through the air outlet duct 201 and be discharged into the indoor space through the air outlet 202, facilitating the air conditioner 1000 to perform air conditioning on the indoor space.

[0056] Among them, the wind guiding assembly 100 has a wind guiding plate 1. The wind guiding plate 1 is rotatably arranged at the air outlet 202 of the air conditioner 1000. In the width direction of the wind guiding plate 1, the wind guiding plate 1 has a first bending portion 11 and a second bending portion 12 connected to each other. In the air flow direction, the first bending portion 11 bends along the clockwise direction, and the second bending portion 12 bends along the counterclockwise direction.

[0057] That is to say, when the air flow passes through the first bending portion 11 at the air outlet 202, the air flow flows along the first bending portion 11, that is, the air flow direction deflects by a certain angle along the clockwise direction. And when the air flow passes through the second bending portion 12, the air flow flows along the second bending portion 12, that is, the air flow direction deflects by a certain angle along the counterclockwise direction. Thus, after the air flow is adjusted by the first bending portion 11 and the second bending portion 12, the deflection angle between the air flow direction flowing out of the wind guiding plate 1 and the air flow direction entering the wind guiding plate 1 is smaller, and the air outlet distance can be ensured while the wind guiding plate 1 adjusts the air outlet direction, which is beneficial to ensuring the heat exchange efficiency of the air conditioner 1000.

[0058] For example, referring to Figure 4 , Figure 9 and Figure 14 , when the parallel air flow flows towards the first bending portion 11, the air flow direction deflects by a certain angle in the clockwise direction. The deflected air flow continues to flow towards the second bending portion 12, and then deflects by a certain angle in the counterclockwise direction, so that the angle deflection between the air flow direction flowing out through the second bending portion 12 and the air flow direction entering the first bending portion 11 becomes smaller. It can be understood that the smaller the deflection angle of the air outlet, the longer the air outlet distance. Thus, the air flow can deflect in the clockwise direction when flowing through the first bending portion 11, and can deflect in the counterclockwise direction when flowing through the second bending portion 12, so that the deflection angle between the air flow direction flowing out of the air guide plate 1 and the air flow direction entering the air guide plate 1 is smaller, and the air outlet distance can be ensured while adjusting the air outlet direction of the air guide plate 1, which is beneficial to ensuring the heat exchange efficiency of the air conditioner 1000.

[0059] In addition, since both the first bending portion 11 and the second bending portion 12 are bent, the resistance of the first bending portion 11 and the second bending portion 12 to the air flow is small, thereby reducing the loss of the air guide plate 1 to the air flow.

[0060] On the other hand, referring to Figure 4 , Figure 9 and Figure 14 , the first bending portion 11 is located on the air inlet side of the air guide plate 1, and the second bending portion 12 is located on the air outlet side of the air guide plate 1. Among them, the parallel arrows in the drawings are the air flow directions. Therefore, during the process of the air flow flowing into the indoor space, it first flows through the first bending portion 11, and after the air flow is guided to deflect in the clockwise direction by the bent part of the first bending portion 11, it flows towards the second bending portion 12, and then the air flow is guided to deflect by a certain angle in the counterclockwise direction by the bent part of the second bending portion 12. However, it can be understood that since the second bending portion 12 extends in the counterclockwise direction, the second bending portion 12 gradually separates from the air flow direction in the direction away from the first bending portion 11. Thus, after the second bending portion 12 adjusts the angle of the air flow, it will not block the air flow out of the air outlet, thereby ensuring smooth air outlet at the air outlet 202.

[0061] It can be understood that in the related art, there is often an uneven air outlet situation in the extending direction of the wind wheel. For example, the air outlet speeds at both ends in the axial direction of the cross-flow wind wheel are slower, while the air outlet speed in the middle region is faster. Moreover, when the cross-flow wind wheel rotates, negative pressure appears inside the air outlet, while the indoor space environment is at positive pressure. Therefore, it is easier for the outside air to return through the regions with slower air outlet speeds of the cross-flow wind wheel to the regions with faster air outlet speeds of the cross-flow wind wheel, that is, the regions with negative pressure inside the air outlet. In addition, when the air outlets at both ends in the length direction of the air outlet, the friction between the air outlet and the side walls at both ends of the air outlet increases the resistance of the air flow, making the air outlet speeds in the regions at both ends in the length direction of the air outlet decrease, increasing the possibility of the outside air returning through the regions with slower air outlet speeds of the cross-flow wind wheel to the regions with faster air outlet speeds of the cross-flow wind wheel, that is, the regions with negative pressure inside the air outlet. Among them, the air return is likely to cause surging noise at the air outlet position of the air conditioner. In addition, the air return will cause the air outlet in the region with slower air outlet to be discontinuous, resulting in a large temperature difference of the air outlet in this region and affecting the comfort of users.

[0062] Therefore, when the air conditioner 1000 blows air into the indoor space through the air outlet 202, by adjusting the included angle relationship between the air deflector 1 and the horizontal plane, the air outlet direction of the air flowing through the air deflector 1 can be better adjusted. Among them, for the sake of simplified description below, the included angle between the air deflector 1 and the horizontal plane is defined as the angle relationship between the relatively straight part in the middle section of the air deflector 1 and the horizontal plane. For example, in the Figures 4 - 6 shown embodiment, the air deflector 1 is perpendicular to the horizontal plane. At this time, the air outlet deflects upward under the guidance of the air deflector 1, and the upward angle of the air outlet is relatively large. In the Figure 7 and Figure 8 shown embodiments, the air deflector 1 is perpendicular to the horizontal plane. At this time, the air outlet deflects downward under the guidance of the air deflector 1, and the downward depression angle of the air outlet is relatively large. Therefore, in the up and down directions, the air deflector 1 can better guide the air outlet to the air outlet region farther from the air deflector 1, so that when the air outlet speed in this region is slower, the air deflector 1 can better supplement the air volume in this region.

[0063] Furthermore, in the Figures 9 - 11 shown embodiment, that is, when the air deflector 1 rotates a certain angle in the counterclockwise direction from the state perpendicular to the horizontal plane, the included angle between the air deflector 1 and the horizontal plane decreases at this time, and the flow direction of the air flow guided by the air deflector 1 deflects synchronously in the counterclockwise direction by an angle, making the upward angle of the air outlet smaller. And in the Figure 12 and Figure 13In the illustrated embodiment, that is, the air deflector 1 rotates a certain angle in the clockwise direction from the state perpendicular to the horizontal plane. At this time, the angle between the air deflector 1 and the horizontal plane decreases, and the flow direction of the air flow guided by the air deflector 1 synchronously deflects in the clockwise direction by an angle, so that the downward depression angle of the air outlet becomes smaller. It can be understood that reducing the upward or downward depression angle can guide the air outlet to an area closer to the air deflector 1 (the air outlet area). When the air outlet speed in this area is slow, the air deflector 1 can better supplement the air volume in this area. And in Figures 14 - 16 the illustrated embodiment and Figure 17 , Figure 18 the illustrated embodiment, it can be ensured that the air outlet passes through the air deflector 1 smoothly, so that the air conditioner 1000 can continuously and stably blow air, meeting the effects of rapid cooling or heating.

[0064] In other words, the air deflector 1 can guide the air outlet to flow at different angles to supplement the area with a slow air outlet speed. And the air deflector 1 can also be in a state with less interference to the air outlet to ensure the stable and continuous air outlet of the air conditioner 1000. Thus, by adjusting the angular relationship between the air deflector 1 and the horizontal plane, the air outlet direction at the air deflector 1 can be better adjusted to guide the air outlet in the area with a fast flow speed to the area with a slow air outlet speed, so that on the air outlet surface of the air outlet 202, the difference in the flow speed of the air flow entering the indoor space is small, and thus the uniform air outlet of the air conditioner 1000 is realized.

[0065] On the other hand, it can better prevent the outside air from flowing back from the area with a slow air outlet speed to the area with a fast air outlet speed inside the air outlet 202, solving the problem of surging noise caused by air flow back inside the air outlet 202. In addition, it can also better prevent the air flow back from hindering the air outlet in the area with a slow flow speed, so that the area with a slow air outlet speed can continuously blow air. Thus, the temperature difference of the air outlet in the area with a slow air outlet speed can be better improved.

[0066] For the air conditioner 1000 according to the embodiment of the present invention, by providing a first bent portion 11 bent in the clockwise direction and a second bent portion 12 bent in the counterclockwise direction, the air flow can deflect in the clockwise direction when flowing through the first bent portion 11, and can deflect in the counterclockwise direction when flowing through the second bent portion 12, so that the deflection angle between the flow direction of the air flow flowing out of the air deflector 1 and the flow direction of the air flow entering the air deflector 1 is small. While adjusting the air outlet direction of the air deflector 1, the air outlet distance can be ensured, which is beneficial to ensuring the heat exchange efficiency of the air conditioner 1000.

[0067] In some embodiments of the present invention, referring to Figure 9, in the direction where the first bending portion 11 extends away from the second bending portion 12, the thickness of the first bending portion 11 gradually decreases, so that the thickness of the end of the first bending portion 11 that first contacts the air flow is smaller, thereby reducing the flow resistance of the first bending portion 11 to the air flow. In the direction where the second bending portion 12 extends away from the first bending portion 11, the thickness of the second bending portion 12 gradually decreases, so that when the air flow passes through the second bending portion 12, the second bending portion 12 gradually moves away from the air outlet direction, thereby reducing the resistance of the second bending portion 12 to the air flow. At the same time, the input of production materials for the air deflector 1 can be reduced, which is beneficial to reducing the weight of the air deflector 1.

[0068] In some other embodiments of the present invention, the air deflector 1 is integrally formed. Thus, the integrally formed structure can not only ensure the structural and performance stability of the first bending portion 11 and the second bending portion 12, but also be convenient for forming, simple in manufacturing, and eliminate unnecessary fittings and connection processes, greatly improving the assembly efficiency of the first bending portion 11 and the second bending portion 12, ensuring the connection reliability of the first bending portion 11 and the second bending portion 12. Moreover, the overall strength and stability of the integrally formed structure are relatively high, the assembly is more convenient, and the service life is longer.

[0069] In some embodiments of the present invention, referring to Figure 4 , Figure 9 and Figure 14 , in the air flow direction, the first bending portion 11 is located upstream of the second bending portion 12. That is to say, during the process of the air flow passing through the air deflector 1, the air flow first passes through the first bending portion 11, so that the flow direction of the air flow is deflected by a certain angle in the clockwise direction under the guidance of the first bending portion 11, and then the air flow flows from the first bending portion 11 to the second bending portion 12, so that the flow direction of the air flow is deflected by a certain angle in the counterclockwise direction under the guidance of the second bending portion 12, thereby completing the adjustment of the air flow direction.

[0070] Among them, referring to Figure 9 , the air outlet direction passing through the air deflector 1 is substantially parallel to the extension direction of the second bending portion 12. Therefore, the air flow with a relatively fast air outlet speed at the rear side of the first bending portion 11 is guided by the air deflector 1 to raise the air outlet angle, so as to guide part of the air flow in the area with a relatively fast air outlet speed to the air outlet area on the upper side of the air deflector 1, thereby supplementing the air volume in the upper side area of the air deflector 1, and can preferably avoid the external air from flowing back from the area with a relatively slow air outlet speed to the area with a relatively fast air outlet speed in the air outlet 202, and solve the problem of surging noise caused by air flow back inside the air outlet 202.

[0071] In some embodiments of the present invention, the deflection angle of the air flow flowing through the first bending portion 11 is α1, and the deflection angle of the air flow flowing through the second bending portion 12 is α2, and it satisfies: α1≥α2. That is to say, the deflection angle generated by the air flow under the guidance of the second bending portion 12 is not greater than the deflection angle generated under the guidance of the first bending portion 11. It can be understood that the deflection angle of the air flow on the first bending portion 11 is consistent with the bending angle of the first bending portion 11, and the deflection angle of the air flow on the second bending portion 12 is consistent with the bending angle of the second bending portion 12, that is, the bending angle of the first bending portion 11 is α1, and the bending angle of the second bending portion 12 is α2. The bending angle here refers to the included angle between the first bending portion 11, the second bending portion 12 and the relatively straight part in the middle section of the air deflector 1. Thus, the flow direction of the air flow can be controlled by setting the bending angles of the first bending portion 11 and the second bending portion 12.

[0072] Among them, when α2 is less than α1, referring to Figure 14 , when the air flow flows into the indoor space through the second bending portion 12, it can preferably avoid the bending part from hindering the flow of the upper air flow, thereby reducing the loss of the air outlet through the air deflector 1.

[0073] In addition, when α1 is equal to α2, in the embodiments shown in Figures 19 - 21 and the embodiments shown in Figure 22 and Figure 23 , the air deflector 1 can be formed into a centrosymmetric structure, and the first bending portion 11 and the second bending portion 12 are centrosymmetric along the connection position of the first bending portion 11 and the second bending portion 12, which can preferably reduce the number of mold openings when producing the first bending portion 11 and the second bending portion 12. In addition, when the air deflector 1 is integrally formed and produced, the mold-making difficulty can be preferably reduced, thereby reducing the production difficulty of the air deflector 1.

[0074] It can be further understood that the air outlet direction at the air outlet 202 is proportional to the bending angle of the second bending portion 12. Referring to Figure 4 and Figure 7 , the smaller the bending angle of the second bending portion 12, the greater the upward or downward angle of the air outlet. On the contrary, referring to Figure 19 and Figure 22 , the larger the bending angle of the second bending portion 12, the smaller the upward or downward angle of the air outlet. Thus, the air outlet angle can be further controlled by controlling the bending angle of the second bending portion 12.

[0075] In some embodiments of the present invention, α2 satisfies: 15° ≤ α2 ≤ 45°. That is to say, the deflection angle of the air flow when flowing through the second bending portion 12 is between 15° and 45° (including 15° and 45°). Thereby, the deflection angle of the air flow when passing through the second air guide plate is relatively small. In a specific example, referring to Figure 4 , α2 is 20°. That is to say, when the air flow flows through the second bending portion 12, the adjustment angle of the second bending portion 12 to the air flow is relatively small, so that the loss during the deflection process of the air flow can be better reduced.

[0076] In some other embodiments of the present invention, α2 satisfies: 45° < α2 ≤ 75°. That is to say, the deflection angle of the air flow when flowing through the second bending portion 12 is between 45° and 75° (not including 45°, including 75°). Thereby, the deflection angle of the air flow on the second bending portion 12 can be better increased. In a specific embodiment, referring to Figure 19 , α2 is 75°. Among them, the range of α2 can be flexibly set according to the requirements of the air guide plate in actual applications. Here, only two embodiments are exemplified, which is not a limitation of the present invention.

[0077] In some embodiments of the present invention, referring to Figure 1 and Figure 2 , there are multiple air guide plates 1, and the multiple air guide plates 1 are arranged in parallel at intervals. Thereby, after the outside air is processed by the air conditioner 1000, it can pass through the air outlet duct 201 and be discharged into the indoor space through the air outlet 202, which is convenient for the air conditioner 1000 to adjust the air in the indoor space.

[0078] It can be understood that the air outlet area that the air guide assembly 100 can guide is proportional to its covering length in the up and down direction. The longer the covering length is, the more air flow is guided by the air guide assembly 100, and the larger the air volume that can be supplemented after being guided by the air guide plate 1 is. Therefore, the number of air guide plates 1 can be increased to increase the covering area of the air guide assembly 100 in the up and down direction. In other words, the number of air guide plates 1 can be flexibly adjusted according to the air outlet state of the air outlet 202. For example, when the area with a relatively slow air outlet speed at the top of the air outlet 202 is relatively large, four or five air guide plates 1 can be set, so as to increase the air volume guided from the area with a relatively fast air outlet speed to the area with a relatively slow air outlet speed at the top of the air outlet 202, and further avoid the outside air from returning from the area with a relatively slow air outlet speed to the area with a relatively fast air outlet speed inside the air outlet 202, so as to solve the problem of surge noise caused by air return inside the air outlet 202.

[0079] In addition, by arranging the air guide plates 1 in parallel at intervals, it can be better ensured that the guiding directions of the multiple air guide plates 1 for the air outlet are the same, as Figure 4As shown, the three guide plates are arranged in parallel, and the air outlet directions of the air flow after being guided by the three air guide plates 1 are also parallel, which can better avoid the air flow disorder caused by different air outlet directions.

[0080] Furthermore, referring to Figure 3 , the air guide assembly 100 further includes: a connecting rod 2 and a driving mechanism 4. Among them, the connecting rod 2 is rotatably connected to multiple air guide plates 1 to enable the multiple air guide plates 1 to rotate synchronously. Thereby, the difficulty of synchronously adjusting the multiple air guide plates 1 is reduced. In addition, the driving mechanism 4 is arranged in the air outlet duct 201, and the driving mechanism 4 is connected to the connecting rod 2. That is to say, by driving the connecting rod 2 to move through the driving mechanism 4, and then driving the multiple air guide plates 1 to rotate synchronously. Thereby, by controlling the movement of the connecting rod 2 through the driving mechanism 4, the included angle relationship between the multiple air guide plates 1 and the horizontal plane can be better adjusted, so that after rotation, the air guide plates 1 can better guide part of the air flow in the area with a faster air outlet speed to the area with a slower air outlet speed, thereby avoiding the outside air from returning from the area with a slower air outlet speed at the air outlet 202 to the area with a faster air outlet speed in the air outlet duct 201, and solving the problem of surge noise caused by the air return in the air outlet duct 201.

[0081] In a specific embodiment, referring to Figure 24 and Figure 25 , the air guide assembly 100 has three air guide plates 1, the left and right ends of the three air guide plates 1 are respectively connected by two fixing rods 3, and the middle position of each air guide plate 1 is rotatably connected to the fixing rod 3. The connecting rod 2 is respectively rotatably connected to one end of the air inlet side of the three air guide plates 1, so that the driving mechanism 4 and the connecting rod 2 can be better hidden at the rear end of the fixing rod 3. Of course, the connecting rod 2 can also be respectively rotatably connected to one end of the air outlet side of the three air guide plates 1, which is not limited here. Therefore, driven by the driving mechanism 4, the connecting rod 2 can be driven to move away from the fixing rod 3, thereby driving the lower ends of the three air guide plates 1 to rotate clockwise around the connection position with the fixing rod 3, and after the air guide plates 1 rotate to a specified angle, the driving mechanism 4 stops driving the connecting rod 2.

[0082] Among them, the angle by which the driving mechanism 4 can drive the three air guide plates 1 to rotate can be set according to the angle by which the air guide plates 1 can rotate. In a specific example, the angle range between the air guide plate 1 and the horizontal plane is 0° to 90°. Therefore, the driving mechanism 4 can drive the connecting rod 2 to move, so as to adjust the included angle between the air guide plate 1 and the horizontal plane to any angle between 0° and 90°.

[0083] In some embodiments of the present invention, referring to Figure 3 and Figure 26, the driving mechanism 4 has an eccentric shaft 41, and the eccentric shaft 41 is rotatably connected to the connecting rod 2. It can be understood that, due to the rotational connection between the connecting rod 2 and the air deflector 1, and the rotational connection between the air deflector 1 and the air outlet 202, referring to Figure 24 and Figure 25 , during the rotation of the air deflector 1, the movement trajectory of the first end of the connection between the air deflector 1 and the connecting rod 2 is an arc. And since the eccentric shaft 41 can swing along an arc under the drive of the driving mechanism 4, when the eccentric shaft 41 swings along the arc, the connecting rod 2 can be synchronously driven to swing along the arc, so as to drive the position where the air deflector 1 is connected to the connecting rod 2 to rotate along the radian, so that one end of the air deflector 1 connected to the connection rotates a certain angle in the clockwise or counterclockwise direction under the drive of the eccentric shaft 41. Thus, by providing the eccentric shaft 41 in the driving mechanism 4, the angle adjustment between the air deflector 1 and the horizontal plane can be better realized.

[0084] Furthermore, referring to Figures 26 - 28 , the air guiding assembly 100 further includes: a limiting guide rail 5, the limiting guide rail 5 is fixed in the air outlet duct 201, the limiting guide rail 5 has a limiting hole 51, and the limiting hole 51 is formed as an arc, and the eccentric shaft 41 is inserted into the limiting hole 51. That is to say, when the driving mechanism 4 drives the eccentric shaft 41 to rotate, the eccentric shaft 41 moves along the limiting hole 51 in the limiting hole 51. Therefore, by setting the upper stop point and the lower stop point of the limiting guide rail 5, that is, the relative two ends in the extending direction of the limiting guide rail 5, the rotation angle of the eccentric shaft 41 can be better limited, that is, the rotation angle of the air deflector 1 can be limited, and the angle deviation during the rotation of the eccentric shaft 41 can be better avoided, so as to realize the precise control of the deflection angle of the air deflector 1.

[0085] In some embodiments of the present invention, in the air flow direction, the first bending portion 11 is located downstream of the second bending portion 12. That is to say, during the air flow, the air flow first passes through the second bending portion 12, so that the air flow direction deflects a certain angle in the counterclockwise direction under the guidance of the second bending portion 12. Then the air flow flows from the second bending portion 12 to the first bending portion 11, so that the air flow direction deflects a certain angle in the clockwise direction under the guidance of the first bending portion 11, thus completing the adjustment of the air flow direction.

[0086] Among them, referring to Figure 7 , the air outlet direction passing through the air deflector 1 is substantially parallel to the extending direction of the first bending portion 11. Therefore, the air flow with a faster air outlet speed at the rear side of the second bending portion 12 is guided by the air deflector 1 to suppress the air outlet angle downward, so as to guide part of the air flow in the area with a faster air outlet speed to the air outlet area below the air deflector 1, thereby supplementing the air volume in the area below the air deflector 1, and can better avoid the outside air from returning to the area with a faster air outlet speed inside the air outlet 202 through the area with a slower air outlet speed, and solves the problem of surge noise caused by air return inside the air outlet 202.

[0087] In some embodiments of the present invention, the ratio of the distance between the installation position of the air guiding assembly 100 and one end in the length direction of the air outlet 202 to the total length of the air outlet 202 is L, and L satisfies: 15% ≤ L ≤ 85%. That is to say, the distances between the installation position of the air guiding assembly 100 and the two ends in the length direction of the air outlet 202 are not less than 15% of the total length of the air outlet 202. It can be understood that, with reference to Figure 4 , the connection position of the first bending portion 11 and the second bending portion 12 is rotatably arranged at the air outlet 202. During the use of the air guiding assembly 100, it is necessary to rotate the air guiding plate 1 to adjust the air outlet angle. Therefore, setting the installation position of the air guiding assembly 100 at intervals from the two ends of the air outlet 202 can preferably prevent the side walls at the two ends of the air outlet 202 from interfering with the rotation of the first bending portion 11 or the second bending portion 12 during the rotation of the air guiding plate 1, which is beneficial to ensuring the smooth rotation of the air guiding plate 1.

[0088] In a specific embodiment of the present invention, with reference to Figure 1 , two air guiding assemblies 100 are arranged at intervals in the up-down direction of the air outlet 202. Each air guiding assembly 100 is provided with three air guiding plates 1. The upper air guiding assembly 100 is arranged at the upper one-third of the air outlet 202, and the lower air guiding assembly 100 is arranged at the lower one-third of the air outlet 202, so that the uppermost air guiding plate 1 in the upper air guiding assembly 100 can rotate smoothly. At the same time, the lowermost air guiding plate 1 in the lower air guiding assembly 100 can rotate smoothly.

[0089] It should be noted that the value range of L here is for the convenience of understanding the installation position of the air guiding assembly 100. The value of L can be set according to the size of the air guiding plate 1, that is, the installation position of the air guiding assembly 100 is not limited here on the premise of not affecting the normal rotation of the air guiding plate 1.

[0090] In some embodiments of the present invention, the air outlet 202 has opposite first end 203 and second end 204. The first end 203 and the second end 204 are respectively provided with a first air guiding plate and a second air guiding plate. The first air guiding plate is the air guiding plate 1 in which the first bending portion 11 is upstream of the second bending portion 12 in the air flow direction, and the second air guiding plate is the air guiding plate 1 in which the first bending portion 11 is downstream of the second bending portion 12 in the air flow direction. The first air guiding plate and the second air guiding plate are adapted to guide the air flow in a direction away from the center of the air outlet 202.

[0091] It can be understood that, at the first end 203 and the second end 204 of the air outlet 202, during the flow of the air outlet airflow, it is necessary to friction against the three side walls in the air outlet duct 201, resulting in a relatively large air outlet resistance at the positions of the first end 203 and the second end 204. As a result, the air outlet speed at the first end 203 and the second end 204 is slower than that in the middle area of the air outlet duct 201. Therefore, by providing the first air deflector and the second air deflector, part of the airflow in the area with a faster air outlet speed in the air outlet duct 201 can be preferably guided in the direction away from the center of the air outlet 202, that is, to the area with a slower air outlet speed, which can preferably prevent the outside air from flowing back through the area with a slower air outlet speed towards the area with a faster air outlet speed inside the air outlet 202, and solve the problem of surge noise caused by air flow back inside the air outlet 202.
