[0007] This disclosure provides a telescopic mechanism for an air guide plate and an air conditioner. By providing a telescopic mechanism in the middle of the air guide plate, the connecting rod of the telescopic mechanism is slidably connected to the air guide plate, so that the telescopic mechanism can adapt to the extension and rotation trajectory of the air guide plate, and the air guide plate can be tightened when closed.

[0008] In some embodiments, the telescopic mechanism for the air guide plate includes a driving element, a connecting rod, and a track plate. The driving element has a rotation center. One end of the connecting rod is slidably connected to the driving element, and the other end is slidably connected to the air guide plate to accommodate the extension and rotation of the air guide plate. The track plate is fixedly disposed inside the air conditioner and includes a linear track. The connecting rod is slidably disposed on the linear track to define the extension direction of the connecting rod. The telescopic mechanism is disposed in the middle of the air guide plate to tighten the air guide plate in the closed state.

[0009] Optionally, the connecting rod includes a sliding groove disposed at the other end of the connecting rod. The connecting rod has a first plate surface that contacts the driving element and a second plate surface that is opposite to the first plate surface. The sliding groove passes through the first plate surface and the second plate surface. A connecting shaft is disposed in the middle of the air guide plate, and the connecting shaft is slidably disposed in the through groove.

[0010] Optionally, the slide groove is arranged along the length of the connecting rod to adapt to the movement trajectory of the air guide plate; when the air guide plate is in the closed state, the connecting shaft is located at the lower end of the slide groove; when the air guide plate is opening upward or downward, the connecting shaft slides from the lower end to the upper end of the slide groove.

[0011] Optionally, the connecting rod further includes a through groove, which is disposed at one end of the connecting rod and located on the first plate surface of the connecting rod; the through groove is slidably connected to the driving element, and the driving element rotates around the rotation center to drive the extension of the connecting rod.

[0012] Optionally, the through groove is straight.

[0013] Optionally, the driving element includes a drive shaft, which is disposed perpendicular to the plate surface of the driving element and is slidably disposed in the slide groove.

[0014] Optionally, the linear track includes at least a first linear track and a second linear track, wherein the first linear track is linear, the second linear track is linear, and the second linear track is arranged parallel to the first linear track.

The first slider group is disposed on the second plate surface and is slidably disposed on the first linear track. The second slider group is disposed on the second plate surface and is slidably disposed on the second linear track.

[0016] Optionally, the first slider group and the second slider group each include at least two sliders.

[0017] In some embodiments, the air conditioner includes the telescopic mechanism for the air guide vane described above.

[0018] The telescopic mechanism for the air guide plate and the air conditioner provided in this disclosure can achieve the following technical effects:

[0019] The telescopic mechanism for the air guide plate provided in this embodiment is disposed in the middle of the air guide plate. The telescopic mechanism includes a driving element, a connecting rod, and a track plate. The driving element has a center of rotation and is slidably connected to one end of the connecting rod. The other end of the connecting rod is slidably connected to the air guide plate. A linear track is provided on the track plate, and the connecting rod is slidably disposed within the linear track. The linear track can limit the direction of extension of the connecting rod. The driving element can rotate under the action of an external force. The driving element is slidably connected to the connecting rod, thereby providing a driving force for the extension of the connecting rod. The connecting rod moves along the linear track under the drive of the driving element, accompanying the extension of the air guide plate. The other end of the connecting rod is slidably connected to the air guide plate. That is, the connection position between the connecting rod and the air guide plate can be adjusted according to the movement trajectory of the air guide plate. During the extension and rotation of the air guide plate, the telescopic mechanism will not interfere with the movement of the air guide plate. Meanwhile, the telescopic mechanism is located in the middle of the air guide plate. When the air guide plate is closed, the connecting rod provides an inward tightening force, ensuring the air guide plate is tightly closed and there are no gaps between the air guide plate and the air outlet of the air conditioner, preventing dust from entering the air conditioner through gaps. The telescopic mechanism for the air guide plate provided in this embodiment is suitable for long air guide plates with a large opening angle. Driven by the drive mechanisms at both ends, the air guide plate first extends and then rotates while extending. The telescopic mechanism for the air guide plate does not interfere with the movement of the air guide plate during its extension and rotation; and when the air guide plate is closed, it can tighten the air guide plate.

[0041] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0043] Currently, for installation environments with large indoor areas, users typically choose 2-horsepower or 3-horsepower air conditioners. These air conditioners are designed for larger indoor areas and offer higher energy efficiency and air volume. To achieve wide-angle airflow or increase cooling or heating capacity, the air outlet of these air conditioners is usually quite long, resulting in a correspondingly long air guide plate 40. However, during long-term use, the air guide plate 40 may deform in the middle due to its length, preventing it from retracting properly when closed and creating a gap between the air guide plate 40 and the air outlet. To address these technical problems, this disclosure provides an air conditioner with an air guide plate 40 featuring a telescopic mechanism.

[0044] This disclosure provides an air conditioner.

[0045] Optionally, the air conditioner includes a housing with an air outlet, an air guide plate 40 at the air outlet, drive mechanisms at both ends of the air guide plate 40, and a telescopic mechanism for the air guide plate 40 at the middle.

[0046] The air conditioner provided in this embodiment is a large guide plate type air conditioner, and the air guide plate 40 can deliver air at a large angle. Specifically, the movement trajectory of the air guide plate 40 is as follows: driven by the drive mechanisms at both ends, the air guide plate 40 first extends out of the air conditioner, and then rotates while extending until it opens upward or downward to the maximum air delivery angle. In this way, in heating mode, the hot air blown out of the air outlet can reach the ground, and in cooling mode, the cold air blown out of the air outlet can rise, improving the heat exchange efficiency between the hot and cold air and the indoor air, thereby improving the cooling and heating effect. At the same time, when the air guide plate 40 is at its maximum opening angle, it is farther away from the air outlet, reducing the noise at the air outlet.

[0047] To accommodate the movement trajectory of the air guide plate 40 in a large guide plate type air conditioner, and to prevent the air guide plate 40 from failing to retract in the closed state due to its own weight, this embodiment provides the following telescopic mechanism for the air guide plate 40. The telescopic mechanism for the air guide plate 40 is located in the middle of the air guide plate 40. During the movement of the air guide plate 40, the telescopic mechanism does not interfere with the movement of the air guide plate 40, and in the closed state, it can provide an inward pulling force to the air guide plate 40, causing the air guide plate 40 to retract.

[0048] Optionally, the air conditioner can be a wall-mounted unit, a ducted unit, or a central air conditioning system. This disclosure does not specifically limit the type of air conditioner.

[0049] Optionally, the side air outlet of the ducted air conditioner is surrounded by an air outlet frame, with an air guide plate 40 on the outside of the air outlet frame and sway vanes inside the air outlet frame for left and right oscillation. In this way, the air guide plate 40 can improve the air delivery direction of the ducted air conditioner, allowing hot air to be blown out from the air outlet frame and blown towards the ground along the air guide plate 40, while cold air can be blown out from the air outlet frame and rise along the air guide plate 40, avoiding direct blowing to the user.

[0050] This disclosure also provides a telescopic mechanism for the air guide plate 40, such as... Figures 1 to 7 As shown.

[0051] In some embodiments, the telescopic mechanism for the air guide plate 40 includes a drive element 10, a connecting rod 20, and a track plate 30. The drive element 10 has a rotation center. One end of the connecting rod 20 is slidably connected to the drive element 10, and the other end is slidably connected to the air guide plate 40 to adapt to the extension and rotation of the air guide plate 40. The track plate 30 is fixedly disposed inside the air conditioner and includes a linear track. The connecting rod 20 is slidably disposed on the linear track to limit the extension direction of the connecting rod 20. The telescopic mechanism is disposed in the middle of the air guide plate 40 to tighten the air guide plate 40 in the closed state.

[0052] The telescopic mechanism for the air guide plate 40 provided in this embodiment is disposed in the middle of the air guide plate 40. The telescopic mechanism includes a driving element 10, a connecting rod 20, and a track plate 30. The driving element 10 has a rotation center and is slidably connected to one end of the connecting rod 20. The other end of the connecting rod 20 is slidably connected to the air guide plate 40. A linear track is provided on the track plate 30, and the connecting rod 20 is slidably disposed within the linear track. The linear track can limit the direction of extension of the connecting rod 20. The driving element 10 can rotate under the action of an external force. The driving element 10 is slidably connected to the connecting rod 20, thereby providing a driving force for the extension of the connecting rod 20. The connecting rod 20 moves along the linear track under the drive of the driving element 10, accompanying the extension of the air guide plate 40. The other end of the connecting rod 20 is slidably connected to the air guide plate 40. That is, the connection position between the connecting rod 20 and the air guide plate 40 can be adjusted according to the movement trajectory of the air guide plate 40. During the extension and rotation of the air guide plate 40, the telescopic mechanism will not interfere with the movement of the air guide plate 40. Meanwhile, the telescopic mechanism is located in the middle of the air guide plate 40. When the air guide plate 40 is closed, the connecting rod 20 can provide an inward tightening force to the air guide plate 40, so that the air guide plate 40 is tightened when closed. There will be no gap between the air guide plate 40 and the air outlet of the air conditioner, preventing dust from entering the air conditioner through the gap.

[0053] The telescopic mechanism for the air guide plate 40 provided in this embodiment is suitable for air guide plates 40 that are relatively long, and the opening angle of the air guide plate 40 is relatively large. Under the drive of the driving mechanisms at both ends, the air guide plate 40 first extends, and then rotates while extending. The telescopic mechanism for the air guide plate 40 does not interfere with the movement of the air guide plate 40 during the extension and rotation process; and it can tighten the air guide plate 40 when it is closed.

[0054] Optionally, the connecting rod 20 includes a slide groove 21, which is disposed at the other end of the connecting rod 20. The connecting rod 20 has a first plate surface that contacts the driving element 10 and a second plate surface that is opposite to the first plate surface. The slide groove 21 passes through the first plate surface and the second plate surface. A connecting shaft 445 is disposed in the middle of the air guide plate 40, and the connecting shaft 445 is slidably disposed in the slide groove 21.

[0055] like Figure 4 and Figure 5 As shown, the connecting rod 20 includes a first plate surface that contacts the driving element 10 and a second plate surface opposite to the first plate surface. A groove 21 is provided at the connection end between the connecting rod 20 and the air guide plate 40, and the groove 21 passes through the first and second plate surfaces of the connecting rod 20. Correspondingly, a connecting shaft 445 is provided in the middle of the air guide plate 40. The connecting shaft 445 is arranged along the length direction of the air guide plate 40 and slidably disposed within the groove 21. Thus, when the air guide plate 40 is closed, the inner peripheral wall of the groove 21 can contact the outer peripheral surface of the connecting shaft 445 and provide a pulling force to the connecting shaft 445 towards the interior of the air conditioner, thereby tightening the air guide plate 40.

[0056] Optionally, the slide 21 is arranged along the length of the connecting rod 20 to adapt to the movement trajectory of the air guide plate 40; when the air guide plate 40 is in the closed state, the connecting shaft 445 is located at the lower end of the slide 21; when the air guide plate 40 is opening upward or downward, the connecting shaft 445 slides from the lower end to the upper end of the slide 21.

[0057] In this embodiment of the disclosure, the lower end of the slide 21 refers to the end of the slide 21 that is close to the air guide plate 40 when the air guide plate 40 is closed; the upper end of the slide 21 refers to the end of the slide 21 that is away from the air guide plate 40 when the air guide plate 40 is closed.

[0058] Understandably, the arrangement of the chute 21 is related to the movement trajectory of the air guide plate 40. The telescopic mechanism for the air guide plate 40 provided in this embodiment includes a drive element 10, a connecting rod 20, and a track plate 30. A linear track is provided on the track plate 30, and the connecting rod 20 can slide along the linear track. The drive element 10 provides driving force for the movement of the connecting rod 20. Thus, the movement trajectory of the telescopic mechanism is that the connecting rod 20 extends or retracts into the air outlet of the air conditioner along the linear track. The connecting rod 20 itself only performs linear motion and does not rotate, which is compatible with the movement trajectory of the air guide plate 40. During the initial extension process, the direction of extension of the air guide plate 40 is the same as the extension direction of the linear track of the telescopic mechanism. Furthermore, during the process of extending and rotating the air guide plate 40, the extension direction of the air guide plate 40 does not change compared to the initial extension process and remains the same as the extension direction of the linear track of the telescopic mechanism. Taking a ducted air conditioner as an example, the extension direction of the straight track of the track plate 30 is horizontal. That is, the air guide plate 40 first extends horizontally outward from the air outlet, and then continues to extend and rotate horizontally. The air guide plate 40 moves continuously in the horizontal direction, and the axis of rotation of the air guide plate 40 also moves horizontally. The axis of rotation of the air guide plate 40 is perpendicular to the extension direction of the straight track of the telescopic mechanism. The extension length of the connecting rod 20 along the straight track may be less than the sum of the extension lengths of the air guide plate 40 during extension and the process of extension and rotation. Therefore, the slide groove 21 can be set as an ellipse, and the major axis of the slide groove 21 is set along the length direction of the connecting rod 20. That is, the extension direction of the slide groove 21 is the same as the extension direction of the air guide plate 40. In this way, a margin can be left for the front and rear horizontal extension of the air guide plate 40, avoiding interference of the telescopic mechanism with the normal movement of the air guide plate 40. For example, the slide groove 21 can be set as an ellipse, and the connecting shaft 445 can be cylindrical to match the movement trajectory of the air guide plate 40.

[0059] Understandably, the connecting shaft 445 is positioned on the rotation axis of the air guide plate 40. The rotation axis of the air guide plate 40 is the axis along the length of the air guide plate. This ensures that the telescopic mechanism does not interfere with the movement trajectory of the air guide plate 40, allowing the air guide plate 40 to rotate normally along its rotation axis.

[0060] Optionally, the connecting rod 20 further includes a through groove 22, which is disposed at one end of the connecting rod 20 and located on the first plate surface of the connecting rod 20; the through groove 22 is slidably connected to the driving element 10, and the driving element 10 rotates around the rotation center to drive the extension of the connecting rod 20.

[0061] The sliding connection between the drive element 10 and the connecting rod 20 is achieved by the sliding of the drive element 10 within the through groove 22. The drive element 10 rotates around its rotation center, providing an outward pushing force for the extension of the connecting rod 20. Optionally, the telescopic mechanism for the air guide plate 40 also includes a motor, which is drivenly connected to the drive element 10, with the motor's drive shaft located at the rotation center of the drive element 10. Optionally, the motor can be a stepper motor.

[0062] Optionally, the through groove 22 is straight.

[0063] Understandably, the drive element 10 transmits the outward pushing force to the connecting rod 20 through the through groove 22. The through groove 22 is straight, which allows the connecting rod 20 to extend outward smoothly. Furthermore, compared to other curved or sawtooth tracks, the through groove 22 and the drive element 10 do not generate any force that hinders the extension of the connecting rod 20, and the connecting rod 20 will not get stuck during the extension process.

[0064] Optionally, the drive element 10 includes a drive shaft 121, which is disposed perpendicular to the plate surface of the drive element 10 and is slidably disposed in the through groove 22.

[0065] In this embodiment, the driving element 10 includes a rotating disk 11 and a rotating rod 12. The rotating disk 11 has a rotation center, one end of the rotating rod 12 is connected to the rotating disk 11, and the other end of the rotating rod 12 is a free end. A transmission shaft 121 is disposed at the free end of the rotating rod 12. During the rotation of the driving element 10, the transmission shaft 121 itself does not rotate; instead, it rotates along the rotation center. The trajectory of the transmission shaft 121 is a partial circle with the rotation center as its center and the effective length of the driving element 10 as its radius. The effective length of the driving element 10 is the distance between the rotation center and the transmission shaft 121.

[0066] Optionally, the length of the through slot 22 is greater than or equal to the distance between the rotation center of the drive element 10 and the drive shaft 121.

[0067] Understandably, the length of the through slot 22 needs to meet the rotation requirements of the drive element 10. When the air guide plate 40 is in the closed state, as... Figure 2 As shown, the drive shaft 121 of the drive element 10 is located in the middle of the through groove 22. When the drive element 10 moves clockwise or counterclockwise, the drive shaft 121 slides from the middle of the through groove 22 towards its end. If the length of the linear track is long enough, the drive element 10 continues to rotate, and the drive shaft 121 moves from the end of the through groove 22 towards its middle position. Thus, the length of the through groove 22 is at least equal to the distance between the rotation center of the drive element 10 and the drive shaft 121. Simultaneously, the length of the through groove 22 is also related to the rotation direction of the drive element 10 driven by the motor.

[0068] Optionally, the stepper motor is a unidirectional rotary motor, and the length of the through slot 22 is greater than or equal to the distance between the rotation center of the drive element 10 and the transmission shaft 121.

[0069] Optionally, the stepper motor is a bidirectional rotary motor, and the length of the through slot 22 is greater than or equal to the diameter of a circle with the rotation center of the drive element 10 as the center and the distance from the rotation center to the transmission shaft 121 as the radius.

[0070] Optionally, the linear track includes at least a first linear track 31 and a second linear track 32, wherein the first linear track 31 is linear, the second linear track 32 is linear, and the second linear track 32 is arranged parallel to the first linear track 31.

[0071] Understandably, there should be at least two linear tracks to constrain the travel of the link 20 in the extension direction and prevent the link 20 from rotating under the drive of the drive element 10.

[0072] Optionally, the linear track is set horizontally, and the extension direction of the linear track is the extension direction of the air guide plate 40. In this way, it can be adapted to the movement trajectory of the air guide plate 40.

[0073] Optionally, the connecting rod 20 may further include at least a first slider group and a second slider group. The first slider group is disposed on the second plate surface and is slidably disposed on the first linear track 31. The second slider group is disposed on the second plate surface and is slidably disposed on the second linear track 32.

[0074] Understandably, the first plate surface of the connecting rod 20 contacts the driving element 10, and the second plate surface of the connecting rod 20 contacts the track plate 30. The second plate surface of the connecting rod 20 is provided with two slider groups adapted to the first linear track 31 and the second linear track 32, such as... Figure 5 As shown, this allows the connecting rod 20 to extend along the track plate 30.

[0075] Optionally, the first slider group and the second slider group each include at least two sliders.

[0076] Understandably, one end of the connecting rod 20 is slidably connected to the linear track, and the other end is slidably connected to the connecting shaft 445 on the air guide plate 40. If both the first and second slider groups have only one slider, the connecting rod 20 will rotate during the movement of the driving element 10, affecting the extension stroke of the connecting rod 20 and interfering with the movement of the air guide plate 40. In this embodiment, the first slider group includes a first slider 23 and a second slider 24, and the second slider group includes a third slider 25 and a fourth slider 26, which can prevent the connecting rod 20 from rotating during the extension process and interfering with the normal movement stroke of the air guide plate 40. Optionally, the first slider 23 and the second slider 24 are arranged in a horizontal direction, and the third slider 25 and the fourth slider 26 are also arranged in a horizontal direction to adapt to the duct machine.

[0077] Optionally, the first and second slider groups may each include three or four sliders, and the number of linear tracks may also be three or four. That is, the number of slider groups is equal to the number of linear tracks, thus preventing the connecting rod 20 from rotating during extension.

[0078] This disclosure also provides an air guide plate 40 that can be connected to a telescopic mechanism for the air guide plate 40, and can also improve the structural strength of the air guide plate 40 and prevent the air guide plate 40 from deforming.

[0079] Optionally, the air guide plate 40 includes an air guide plate body 41, a first reinforcing mechanism 42, a second reinforcing mechanism 43, and a connecting mechanism. The first reinforcing mechanism 42 is disposed on the inner side wall of the air guide plate body 41 along the length direction of the air guide plate body 41, and the second reinforcing mechanism 43 is disposed on the inner side wall of the air guide plate body 41 along the length direction of the air guide plate body 41, and is disposed side by side with the first reinforcing mechanism 42 to reduce the deformation of the air guide plate 40 during use. One end of the connecting mechanism is connected to the first reinforcing mechanism 42, and the other end is connected to the second reinforcing mechanism 43. The connecting mechanism is connected to the telescopic mechanism for the air guide plate 40 so that the air guide plate 40 is tightened in the closed state.

[0080] In this embodiment, the connecting mechanism can not only connect the first reinforcing mechanism 42 and the second reinforcing mechanism 43, thus improving the structural strength of the air guide plate 40 in its length direction and reducing the deformation of the air guide plate 40 during user use; the connecting mechanism can also be connected to the telescopic mechanism of the air guide plate 40, that is, the telescopic mechanism is connected to the middle area of ​​the air guide plate 40. When the air guide plate 40 is closed, the telescopic mechanism can provide an inward pulling force to the air guide plate 40, greatly reducing the gap between the air guide plate 40 and the air outlet, so that the air guide plate 40 can be tightened in the closed state.

[0081] Optionally, the first reinforcing mechanism 42 and the second reinforcing mechanism 43 are mirror-symmetrically arranged along the longitudinal centerline of the air guide plate body 41. In this way, the air guide plate 40 is subjected to balanced forces at both ends during movement, allowing it to move smoothly and preventing it from becoming uneven during air delivery.

[0082] Optionally, the connecting mechanism includes a first connecting part, a second connecting part, and a connecting shaft 445. The first connecting part includes a first connecting plate 441 and a second connecting plate 442 that are vertically connected. One end of the first connecting plate 441 is connected to the side of the first reinforcing mechanism 42, and the second connecting plate 442 is vertically connected to the inner sidewall of the air guide plate body 41. The second connecting part includes a third connecting plate 443 and a fourth connecting plate 444 that are vertically connected. One end of the third connecting plate 443 is connected to the side of the second reinforcing mechanism 43, and the fourth connecting plate 444 is vertically connected to the inner sidewall of the air guide plate body 41. The connecting shaft 445 is vertically disposed on the outer plate surface of the second connecting plate 442 or the fourth connecting plate 444, and the connecting shaft 445 is slidably connected to the connecting rod 20 of the telescopic mechanism.

[0083] In this embodiment of the disclosure, the structure of the connecting mechanism is as follows: Figure 9 As shown. The first connecting plate 441 and the second connecting plate 442 are vertically connected. The first connecting plate 441 is connected to the side of the first reinforcing mechanism 42, and the height of the second reinforcing plate 421 is less than that of the first reinforcing mechanism 42. A stepped structure is formed between the first connecting part and the first reinforcing mechanism 42. Similarly, the third connecting plate 443 and the fourth connecting plate 444 are vertically connected. The third connecting plate 443 is connected to the side of the second reinforcing mechanism 43, and the height of the fourth reinforcing plate 421 is less than that of the second reinforcing mechanism 43. A stepped structure is also formed between the second connecting part and the second reinforcing mechanism 43. The stepped structure inside the first reinforcing mechanism 42 and the stepped structure inside the second reinforcing mechanism 43 are beneficial to improving the lateral structural strength of the air guide plate body 41, especially the structural strength of the middle area of ​​the air guide plate 40, and reducing the degree of deformation of the air guide plate 40.

[0084] Optionally, a connecting rib 446 is provided between the second connecting plate 442 and the fourth connecting plate 444 to enhance the structural strength of the air guide plate body 41 in the length direction.

[0085] Optionally, the first reinforcing mechanism 42 and / or the second reinforcing mechanism 43 include a reinforcing plate 421 and a plurality of supporting plates 422. The reinforcing plate 421 is flat and is arranged along the length of the air guide plate body 41. The plurality of supporting plates 422 are vertically arranged on the inner sidewall of the air guide plate body 41. The supporting plates 422 are used to support the reinforcing plate 421, and the reinforcing plate 421 is inclinedly arranged on the supporting plate 422.

[0086] Understandably, the arrangement of the support plate 422 and reinforcing plate 421 on the air guide plate body 41 makes the structure of the first reinforcing mechanism 42 and the second reinforcing mechanism 43 resemble an arch structure, spanning both ends of the inner wall of the air guide plate body 41. When the length of the air guide plate 40 is relatively long, the air guide plate 40 will exert downward pressure on the first reinforcing mechanism 42 or the second reinforcing mechanism 43 due to its own gravity. The first reinforcing mechanism 42 or the second reinforcing mechanism 43 can transmit the pressure at the point of force to the adjacent structure, that is, it can generate an outward thrust, thereby bearing and offsetting the pressure caused by the deformation of the air guide plate 40, preventing the air guide plate 40 from deforming during user use, and improving the structural strength of the air guide plate 40.

[0087] Optionally, the first reinforcing mechanism 42 or the second reinforcing mechanism 43 may have a number of support plates 422 greater than or equal to 3 and less than or equal to 7.

[0088] In this embodiment, the number of support plates 422 affects the maximum deformation of the air guide plate 40. When the number of support plates 422 is large or small, the maximum deformation of the air guide plate 40 is large. When either the first reinforcing mechanism 42 or the second reinforcing mechanism 43 has a number of support plates 422 greater than or equal to 3 and less than or equal to 7, the air guide plate 40 has a smaller deformation, thereby improving the structural strength of the air guide plate 40.

[0089] Optionally, on the same side of the reinforcing plate 421, the vertical distance between the end of the reinforcing plate 421 near the middle of the air guide plate body 41 and the inner wall of the air guide plate body 41 is m, and the vertical distance between the end of the reinforcing plate 421 near the end of the air guide plate body 41 and the inner wall of the air guide plate body 41 is n, where m > n.

[0090] In this embodiment of the present disclosure, when the air conditioner is oriented, the reinforcing plate 421 has a windward side facing the inside of the air conditioner's air outlet and an air outlet side facing the outside of the air conditioner's air outlet. For example... Figure 10 As shown, m > n. In this way, when the first reinforcing mechanism 42 or the second reinforcing mechanism 43 is subjected to pressure, it can transmit the downward pressure at the point of force application to both ends of the reinforcing plate 421, thus preventing the deformation of the air guide plate 40.

[0091] Optionally, on the same side of the reinforcing plate 421, 2mm ≤ mn ≤ 5mm. In this way, on the air inlet side or windward side of the reinforcing plate 421, the angle between the reinforcing plate 421 and the inner wall of the air guide plate body 41 is small, and the degree of arching of the first reinforcing mechanism 42 and the second reinforcing mechanism 43 is small, which will not affect the air blowing effect of the air guide plate 40. At the same time, the air guide plate 40 can also have a better anti-deformation effect.

[0092] Optionally, the height difference between the first position on the air outlet side of the reinforcing plate 421 and the inner wall of the air guide plate body 41, and the second position on the windward side corresponding to the first position and the inner wall of the air guide plate body 41, is in the range of 7mm≤cd≤9mm.

[0093] like Figure 11 As shown, the first position on the air outlet side and the second position on the windward side are located on the same longitudinal section of the reinforcing plate 421. c is the distance between the first position on the air outlet side and the inner wall of the air guide plate body 41, and d is the distance between the second position on the windward side and the inner wall of the air guide plate body 41. The difference between c and d is between 7mm and 9mm. In this way, the first reinforcing mechanism 42 and the second reinforcing mechanism 43 can simultaneously improve the strength of the air guide plate body 41 and the effect of air blowing.
