[0030] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0031] like Figure 13 and Figure 14 As shown, this application embodiment provides an air guide plate, including: an air guide plate body 23 (as shown in the image). Figure 1 and Figure 6 (as shown) and the integrally foamed insulation component 24, such as Figure 5 As shown.

[0032] Among them, such as Figure 3 and Figure 4 As shown, the air guide plate body 23 has a first foaming space 251 and a second foaming space 252 on both sides in the thickness direction. The air guide plate body 23 also has an overflow hole 231 that connects the first foaming space 251 and the second foaming space 252. Figure 4 and Figure 8As shown. The insulation component 24 fills the first foaming space 251, the second foaming space 252, and the overflow hole 231, as shown. Figure 5 As shown. The insulation component 24 can be, but is not limited to, foamed rubber.

[0033] The air guide plate provided in this embodiment has a first foaming space 251, a second foaming space 252, and an overflow hole 231 connecting the first and second foaming spaces 251 and 252. Therefore, during the foaming process, the foaming material can flow between the first and second foaming spaces 251 and 252, allowing for double-sided foaming through a single foaming process to obtain an integrally foamed insulation component 24. This simplifies the processing steps of the air guide plate. Furthermore, this design ensures that both sides of the air guide plate body 23 have insulation layers, improving the insulation effect. The integral connection of the insulation layers on both sides allows for mutual restraint, reducing the risk of the insulation component 24 detaching and improving the air guide plate's resistance to deformation.

[0034] In some exemplary embodiments, such as Figure 7 As shown, the second foaming space 252 includes a first strip-shaped groove 2521 extending along the length of the air guide plate. There are multiple overflow holes 231, which are spaced apart along the length of the first strip-shaped groove 2521 on the bottom wall of the first strip-shaped groove 2521.

[0035] In this way, the foaming material can flow through multiple overflow holes 231 during the foaming process, which helps to improve the uniformity of the foaming material in the first strip groove 2521 along the length of the air guide plate, thereby helping to reduce appearance defects.

[0036] In some exemplary embodiments, the bottom wall of the first strip groove 2521 is also provided with a hot nozzle 233 (e.g., Figure 7 (as shown) and exhaust port 232 (as shown) Figure 10 As shown, the hot nozzle 233, vent 232, and overflow hole 231 are staggered. The air guide plate body 23 can be a plastic part, and the hot nozzle 233 is a structure formed during the molding process of the air guide plate body 23. The flow cross-sectional area of ​​the overflow hole 231 is larger than the flow cross-sectional area of ​​the vent 232. At least one vent 232 is provided between the overflow hole 231 and the hot nozzle 233.

[0037] The vent 232 can be used for venting and can also be used to assist in the flow of foaming material, so that the space between the overflow hole 231 and the hot nozzle 233 can also have foaming material flowing quickly, so as to achieve uniform foaming molding and reduce appearance defects.

[0038] The shape of the overflow hole 231 is not limited and can be, but is not limited to, square, triangle, circle, isosceles trapezoid, hexagon, etc. Similarly, the shape of the vent hole 232 is also not limited and can be, but is not limited to, square, triangle, circle, isosceles trapezoid, hexagon, etc.

[0039] In some exemplary embodiments, such as Figure 10 As shown, at least some of the adjacent overflow holes 231 are also provided with vent holes 232, which can allow foaming material to flow quickly between adjacent overflow holes 231, so as to achieve uniform foaming and molding, which helps to reduce appearance defects.

[0040] In some exemplary embodiments, such as Figure 10 As shown, at least some of the overflow holes 231 are evenly spaced (e.g., spaced 10mm apart), which helps to improve the uniformity of the foaming material in the first strip groove 2521, so as to achieve uniform foaming and molding, and help to reduce appearance defects.

[0041] In some exemplary embodiments, the first strip groove 2521 has a defect-prone area 234, such as... Figure 11 The area enclosed by the dashed ellipse is shown. Area 234, prone to defects, can be identified as a region where cracks frequently occur during prototyping, based on observations from the prototyping process. Area 234 may include the region adjacent to the support axis 2378 described below.

[0042] The defect-prone area 234 is provided with multiple vent holes 232, which can increase the flowability of the foam material in the defect-prone area 234. This allows the foam material to flow quickly into the defect-prone area 234, so as to achieve uniform foaming and molding, thereby helping to reduce defects.

[0043] In some exemplary embodiments, such as Figure 7 As shown, the second foaming space 252 also includes a second strip-shaped groove 2522 extending along the width direction of the air guide plate. The second strip-shaped groove 2522 is connected to the first strip-shaped groove 2521, and the bottom wall of the second strip-shaped groove 2522 is also provided with an overflow hole 231, such as... Figure 7 As shown. The number of overflow holes 231 within the second strip-shaped groove 2522 can also be multiple, with the multiple overflow holes 231 spaced apart along the width direction of the air guide plate. The shape of the overflow holes 231 within the second strip-shaped groove 2522 can be, but is not limited to, rectangular.

[0044] This increases the contact area between the insulation component 24 and the air guide plate body 23, which helps to improve the bonding strength between the insulation component 24 and the air guide plate body 23, and also helps to improve the constraint effect of the insulation layers on both sides of the air guide plate body 23, so that the insulation layers on both sides pull each other, thereby further reducing the risk of the insulation component 24 falling off.

[0045] In some exemplary embodiments, the end of the second strip groove 2522 away from the first strip groove 2521 is provided with an anti-torsional protrusion 235, such as... Figure 7 As shown. Experiments have verified that the anti-torsional protrusion 235 can improve the torsional stiffness of the air guide plate and reduce the risk of torsional deformation of the air guide plate. The anti-torsional protrusion 235 can be arranged circumferentially along the overflow hole 231 at the end of the second strip groove 2522.

[0046] In some exemplary embodiments, there are two second strip-shaped grooves 2522, and the two second strip-shaped grooves 2522 are symmetrically arranged. This makes the structure at both ends of the air guide plate symmetrical in the length direction, which helps to reduce the risk of torsional deformation of the air guide plate.

[0047] In some exemplary embodiments, such as Figure 2 As shown, the air guide plate body 23 includes a main body portion 236 and a rotary connecting portion 237 arranged and connected to each other along the width direction of the air guide plate body 23. The rotary connecting portion 237 is configured to be connected to a drive mechanism (such as a stepper motor). A first strip groove 2521 is provided in the width direction of the main body portion 236 near the edge region of the rotary connecting portion 237, and a second strip groove 2522 is provided in the length direction of the main body portion 236.

[0048] In this way, the second foaming space 252 forms a U-shaped structure extending circumferentially along the main body 236, which facilitates the sealing of the circumferential edge of the air guide plate with other structures through overlapping. Furthermore, the area of ​​the part of the main body 236 not covered by the insulation member 24 on the side where the second foaming space 252 is located is relatively large, which, as an appearance surface, helps to improve the aesthetics of the air guide plate.

[0049] In one embodiment, such as Figure 10 As shown, the overflow hole 231 located within the first strip-shaped groove 2521 is an isosceles trapezoid, and the vent hole 232 is circular. Experiments revealed that the probability of defects occurring in the portion of the insulation component 24 near the rotating connection portion 237 is greater than the probability of defects occurring in the portion of the insulation component 24 farther from the rotating connection portion 237. Therefore, as... Figure 10 As shown, the length of the end of the overflow hole 231 in the first strip groove 2521 near the rotating connection 237 is greater than the length of the end of the overflow hole 231 near the main body 236, so that the foaming material can reach the part near the rotating connection 237 more quickly and evenly, thereby reducing the probability of defects occurring in the part of the insulation component 24 near the rotating connection 237.

[0050] In some exemplary embodiments, such as Figure 2As shown, the air guide plate body 23 includes a main body portion 236 and a rotary connecting portion 237 arranged and connected to each other along the width direction of the air guide plate body 23. The rotary connecting portion 237 is configured to be connected to the drive mechanism, and the two ends of the main body portion 236 in the width direction are provided with a first baffle 2381 and a second baffle 2382, as shown. Figure 9 As shown.

[0051] The first retaining edge 2381, the main body 236, the second retaining edge 2382, and the rotating connecting part 237 enclose the first foaming space 251. A portion of the main body 236 is recessed toward the side where the first foaming space 251 is located to form a second foaming space 252.

[0052] Therefore, the first foaming space 251 is relatively large, and the second foaming space 252 is relatively small. The side containing the first foaming space 251 can be referred to as the back side of the air guide plate body 23, and the side containing the second foaming space 252 can be referred to as the front side of the air guide plate body 23. The main body 236 does not have a recessed portion and can be arc-shaped as a whole along its width direction. The front of the main body 236 is convex, and the back of the main body 236 is concave. In this way, the end of the main body 236 away from the rotating connection portion 237 does not need to be provided with a baffle, so that the back side of the air guide plate body 23 can enclose the first foaming space 251.

[0053] In some exemplary embodiments, such as Figure 9 As shown, the rotating connection part 237 is provided with a filling groove 2514, and the first foaming space 251 includes the filling groove 2514. In this way, a part of the insulation component 24 can be embedded in the filling groove 2514, which helps to increase the contact area between the insulation component 24 and the air guide plate body 23, thereby improving the connection strength and reducing the risk of the insulation component 24 falling off.

[0054] The first foaming space 251 also includes edge regions that are disposed opposite to and correspond to the second foaming space 252. The edge regions include a first strip-shaped region 2511 extending along the length direction of the main body 236, and two second strip-shaped regions 2512 extending along the width direction of the main body 236, such as... Figure 9As shown, the first strip-shaped area 2511 is adjacent to and connected to the filling groove 2514, and the two second strip-shaped areas 2512 are respectively connected to the ends of the first strip-shaped area 2511 along its length. In other words, the first strip-shaped area 2511 is positioned opposite to the first strip-shaped groove 2521 of the second foaming space 252, and the second strip-shaped area 2512 is positioned opposite to the second strip-shaped groove 2522 of the second foaming space 252. In this way, the portion of the insulation component 24 located in the first strip-shaped area 2511 and the portion located in the first strip-shaped groove 2521 pull against each other, and the portion of the insulation component 24 located in the second strip-shaped area 2512 and the portion located in the second strip-shaped groove 2522 pull against each other, which helps to reduce the risk of the insulation component 24 falling off.

[0055] The first foaming space 251 also includes the main body area 2513 located within the space enclosed by the strip-shaped areas, such as Figure 9 As shown, the main body 236 is provided with a baffle rib 2391 extending along the boundary line between the edge area and the main body area 2513. The baffle rib 2391 separates the main body area 2513 from the edge area. In this way, during glue injection, the glue can be injected into the main body area 2513, allowing the glue to foam and form first within the main body area 2513. Only after the foaming in the main body area 2513 is basically completed will the glue pass through the baffle rib 2391 and enter the edge area and the second foaming space 252, where it will then foam and form. This avoids the glue from being injected directly into the second foaming space 252 through the edge area, which would result in excessive glue in the second foaming space 252 and cause glue overflow, thus helping to avoid glue overflow on the front of the air guide plate and causing appearance defects.

[0056] It is understandable that the height of the adhesive baffle 2391 is less than the thickness of the molded insulation component 24. The thickness of the adhesive injected into the main body area 2513 is not higher than the height of the adhesive baffle 2391, but during the foaming process, the adhesive will expand and pass through the adhesive baffle 2391 to reach the edge area and enter the second foaming space 252 through the overflow hole 231, and then foam and form in the edge area and the overflow hole 231.

[0057] In some exemplary embodiments, the main body area 2513, the first strip area 2511, and the filling groove 2514 are provided with mesh-like dense ribs 2397, such as... Figure 10 As shown. The reinforcement rib 2397 is hidden inside the insulation component 24. The reinforcement rib 2397 includes multiple first sub-ribs 2392, such as... Figure 9 As shown, each first sub-rib 2392 is connected to at least two first sub-ribs 2392, and the angle between any two connected first sub-ribs 2392 is 120°.

[0058] Among them, the reinforced ribs 2397 enclose a honeycomb groove structure within the main body area 2513 and the first strip area 2511, and the reinforced ribs 2397 enclose multiple isosceles trapezoidal grooves 2395 within the filling groove 2514, such as Figure 9 and Figure 10 As shown.

[0059] Therefore, the reinforcement ribs 2397 can enclose multiple hexagonal prism-shaped honeycomb holes 2393. Of course, the grooves at the edges of the reinforcement ribs 2397 do not have to be circumferentially closed; they can only enclose a portion of the hexagonal prism.

[0060] Because a relatively large portion of the reinforcement ribs 2397 are located within the main body area 2513 and the first strip area 2511, multiple hexagonal prism-shaped honeycomb holes 2393 can be formed within these areas. However, the portion located at the edges of the main body area 2513 and the first strip area 2511 can only form a portion of the honeycomb holes 2393 (e.g., isosceles trapezoids, triangles, or pentagons). Furthermore, due to the limited space in the filling groove 2514, the reinforcement ribs 2397 form multiple isosceles trapezoidal grooves 2395 within the filling groove 2514, such as... Figure 9 and Figure 10 As shown. The inclined first sub-rib 2392 and the second sub-rib 2394 can form a structure similar to a triangular rib. The triangular rib structure has higher strength and is more stable, which is beneficial to improving the structural strength of the rotary connection 237.

[0061] In some exemplary embodiments, the encryption rib 2397 further includes a second sub-rib 2394, such as... Figure 9 As shown, the second sub-rib 2394 is located within the isosceles trapezoidal groove 2395 and is connected to the groove wall of the isosceles trapezoidal groove 2395, and the isosceles trapezoidal groove 2395 is mirror-symmetric about the second sub-rib 2394. There are multiple second sub-ribs 2394, such as... Figure 9 As shown, at least a portion of the isosceles trapezoidal groove 2395 is provided with a second sub-rib 2394. The second sub-rib 2394 can further improve the structural strength of the rotary connection 237.

[0062] The cross-section of the filling groove 2514 can be arc-shaped. The rotating connection part 237 can be provided with a connecting arm 2370 extending along the length of the air guide plate, such as... Figure 18 As shown, the portion of the reinforced rib 2397 within the filling groove 2514 is divided into two groups. One group is located between one circumferential end of the filling groove 2514 and the connecting arm 2370, and the other group is located between the other circumferential end of the filling groove 2514 and the connecting arm 2370. One end of the second sub-rib 2394 is connected to the connecting arm 2370. This design helps to further improve the structural strength of the rotary connection 237.

[0063] In some exemplary embodiments, the height of the portion of the encryption rib 2397 located within the main body region 2513 varies in a wave-like pattern along the width direction of the main body portion 236, such as... Figure 12 As shown. Among them, the height and curvature of the 2397 densified rib can be designed in the opposite direction based on the deformation direction of the air guide plate obtained from simulation results or experiments, so as to improve the torsional performance of the air guide plate.

[0064] For example, based on simulation results or experimental findings, if the air guide plate is prone to deformation at a certain location, the height of the reinforced rib 2397 at that location will be designed to be higher to increase the difficulty of deformation. Conversely, if the air guide plate is not easily deformed at a certain location, the height of the reinforced rib 2397 at that location will be designed to be lower. This yields the height and curvature distribution of the reinforced rib 2397.

[0065] In some exemplary embodiments, such as Figure 15 and Figure 16 As shown, the rotary connecting portion 237 has a columnar first connecting portion 2371 and a columnar second connecting portion 2372 at its two ends along its length. The first connecting portion 2371 and the second connecting portion 2372 are respectively provided with a first shaft hole 2373 and a second shaft hole 2374. The first shaft hole 2373 is configured to tightly fit (e.g., interference fit or transition fit) with the first driving member of the driving mechanism, and the second shaft hole 2374 is configured to loosely fit (e.g., clearance fit) with the second driving member of the driving mechanism. The first driving member can be, but is not limited to, a stepper motor, and the second driving member can be, but is not limited to, a stepper motor.

[0066] Therefore, the air guide plate can be driven by dual motors, which is beneficial for the even distribution of force on the long air guide plate, thereby reducing the risk of torsional deformation. Furthermore, the first shaft hole 2373 is tightly fitted with the first driving component, and the second shaft hole 2374 is loosely fitted with the second driving component. Thus, the first driving component can be called the main driving component, and the second driving component can be called the auxiliary driving component. This provides driving force to the air guide plate and allows for a certain degree of relative movement between the air guide plate and the second driving component, preventing jamming due to thermal expansion and contraction or asynchronous rotation among the first driving component, air guide plate, and second driving component.

[0067] The gap between the output shaft of the second drive component and the wall of the second shaft hole 2374 can be, but is not limited to, 0.1mm. An axial movement space, such as 3mm, can be reserved between the main body of the second drive component and the air guide plate to facilitate the installation and disassembly of the air guide plate with the first and second drive components. For example, the air guide plate can be tilted to connect with the second drive component first, and then moved closer to the first drive component to connect with it. During disassembly, the air guide plate can be moved closer to the second drive component until it detaches from the first drive component, and then tilted to remove the air guide plate from the first drive component.

[0068] In some exemplary embodiments, a countersunk plate 2376 is provided at the end of the second shaft hole 2374 away from the first shaft hole 2373, such as... Figure 16 As shown, this helps prevent the air guide plate from jamming due to the force exerted on the second drive component during thermal expansion and contraction.

[0069] In some exemplary embodiments, the wall thickness of the first connecting portion 2371 is greater than the wall thickness of the main body portion 236, which helps to prevent the first connecting portion 2371 from breaking under stress in extreme cases.

[0070] The wall thickness of the second connecting part 2372 is greater than that of the main body part 236, which helps to prevent the second connecting part 2372 from breaking under stress in extreme cases.

[0071] In some exemplary embodiments, the central portion of the rotating connection 237 is further provided with a positioning groove 2375, such as... Figure 21 As shown, the positioning groove 2375 is configured to insert into the positioning shaft 16 of the support carrier (such as the air guide bracket), which helps to prevent the air guide plate from moving too much axially during the drop and thus coming loose. The positioning groove 2375 can be located at the exact center of the rotating connection 237.

[0072] In some exemplary embodiments, based on deformation simulation results, the thickness of the air guide plate body 23 can be increased, decreased, and then increased again along the direction from the rotating connection 237 to the other end of the width direction of the air guide plate body 23. For example: Figure 17 As shown, the main body 236 includes a first region 2361, a second region 2362, a third region 2363, and a fourth region 2364 arranged sequentially along the width direction of the air guide plate. The first region 2361 is the area in the main body 236 where a first strip-shaped groove 2521 is formed. The wall thickness t1 of the rotating connection 237 can be 2.3 mm, the wall thickness t2 of the first region 2361 and the wall thickness t3 of the second region 2362 can be 2.5 mm, the wall thickness t4 of the third region 2363 can be 2.3 mm, and the wall thickness t5 of the fourth region 2364 can be 2.5 mm. This design can reduce the risk of torsional deformation of the air guide plate.

[0073] In some exemplary embodiments, the rotating connection 237 further includes at least one third connection, which is configured to be rotatably connected to the support carrier to prevent the air guide plate from detaching from the support carrier. The third connection is located between the first connection 2371 and the second connection 2372. The third connection includes a support shaft 2378, such as... Figure 10 As shown.

[0074] When the third connecting part includes the support shaft 2378, the support carrier can be provided with a support hole and a guide notch communicating with the support hole, so that the support shaft 2378 can be inserted into the support hole by the guide notch and can rotate relative to the support hole.

[0075] like Figure 10 As shown, the rotary connection 237 is provided with a relief groove 2377, and the support shaft 2378 is located within the relief groove 2377. In this way, the diameter of the support shaft 2378 is smaller than the diameter of the rotary connection 237 and is concentrically arranged with the rotary connection 237. While providing support, it can reduce the contact area between the support shaft 2378 and the support carrier, which is beneficial to reducing frictional resistance.

[0076] The number of third connecting parts can be multiple, and the multiple third connecting parts are spaced apart along the length direction of the air guide plate.

[0077] In some exemplary embodiments, the portion of the main body 236 corresponding to the third connecting portion is further provided with a third sub-rib 2396 extending along the width direction of the main body 236, such as... Figure 10 As shown. Since the third connection part needs to cooperate with the supporting carrier and will be under stress, a third sub-rib 2396 is added here to strengthen this part and reduce the risk of deformation of the air guide plate at this point.

[0078] Among them, such as Figure 10 As shown, a third connecting part can correspond to two third sub-ribs 2396. The two third sub-ribs 2396 are respectively set to correspond to the two ends of the relief groove 2377, and can extend from the bottom wall of the relief groove 2377 to a position flush with the reinforcement position 2397.

[0079] In some exemplary embodiments, such as Figure 18 As shown, the clearance groove 2377 is provided with a limiting structure 2380 for cooperating with the blocking member 27. The blocking member 27 is configured to isolate the clearance groove 2377 from the first foaming space 251 and the second foaming space 252 during the foaming process of the insulation member 24.

[0080] This avoids the situation where the colloid overflows into the relief groove 2377 during the foaming process, causing the relief groove 2377 or the support shaft 2378 to be partially covered by the insulation component 24. After the foaming is completed, the blocking component 27 can be removed without cleaning the support shaft 2378 and the relief groove 2377.

[0081] As for the positioning groove 2375, there is no need to set the blocking part 27, because there is no support shaft 2378 in the positioning groove 2375, and the structure is relatively flat. Even if there is excess glue, it is easy to clean after foaming.

[0082] The specific structural form of the limiting structure 2380 is not restricted. For example: Figure 18 As shown, the limiting structure 2380 may include a positioning rib extending along the length direction of the air guide plate and limiting protrusions at both ends of the clearance groove 2377 along the length direction. The blocking member 27 may be provided with a slot for engaging the support shaft 2378, a positioning groove that mates with the positioning rib, and a limiting groove that mates with the limiting protrusions. Furthermore, the cross-sectional outline of the positioning groove may include: an arc segment adapted to the diameter of the support shaft 2378 and two parallel straight line segments, the diameter of the arc segment being greater than the distance between the two straight line segments. In this way, when the blocking member 27 is engaged in the clearance groove 2377, it is not easy to detach from the air guide plate body 23.

[0083] In some exemplary embodiments, such as Figure 10 As shown, the outer wall of the support shaft 2378 is provided with an oil storage groove 2379, which can be used to add lubricating oil, so as to facilitate the relative rotation and lubrication of the air guide plate and the support carrier.

[0084] In some exemplary embodiments, the portion of the insulation member 24 located within the first foaming space 251, away from the rotating connection portion 237, is provided with a thinning portion 241, so that the end of the air guide plate away from the rotating connection portion 237 forms a stepped portion 26, such as... Figure 4 and Figure 5 As shown.

[0085] Experiments have shown that this design helps reduce deformation of the air guide plate in the width direction. In addition, the step portion 26 facilitates the two air guide plates (such as the first air guide plate 21 and the second air guide plate 22 described below) to achieve a tight seal through the two step portions 26 without the sealed area being too thick.

[0086] In some exemplary embodiments, such as Figure 7 and Figure 9As shown, at least a portion of the circumferential edge of the air guide plate body 23 is provided with a glue-blocking protrusion 2383, and the thickness W0 of the glue-blocking protrusion 2383 is greater than 2.5mm. The thickness of the glue-blocking protrusion 2383 is the width of the mating edge sealing between the air guide plate body 23 and the insulation component 24. When the width of the mating edge sealing is greater than 2.5mm, the glue-blocking protrusion 2383 can play a good role in blocking glue, which helps to prevent the glue from overflowing to the circumferential outer side of the air guide plate body 23 during the foaming molding process.

[0087] The rubber-blocking boss 2383 may include the first baffle 2381 and the second baffle 2382 mentioned above, and may also include a boss located at the rotary connection 237 and extending along the length direction of the air guide plate.

[0088] Of course, the thickness of the adhesive-blocking boss 2383 is not limited to the above range and can be adjusted as needed.

[0089] In some exemplary embodiments, the minimum depth of the first foaming space 251 is greater than 1 mm, and the minimum depth h of the second foaming space 252 is (e.g., ...). Figure 7 (As shown) The thickness should be greater than 1mm, which can reduce the difficulty of foaming and facilitate successful foaming.

[0090] The depth h of the main body of the first foaming space 251 can be greater than 1.5 mm, and the depth h of the local extreme positions (such as corner positions or positions with protrusions) can be greater than 1 mm. Similarly, the depth h of the main body of the second foaming space 252 can be greater than 1.5 mm, and the depth h of the local extreme positions (such as corner positions or positions with protrusions) can be greater than 1 mm.

[0091] like Figure 19 and Figure 20 As shown in the illustration, this application also provides an air conditioner, including a housing and an air guiding mechanism. The housing has an air duct 14 and an air outlet communicating with the air duct 14. The air guiding mechanism includes a drive mechanism and an air guide plate as described in any of the above embodiments, the air guide plate being located at the air outlet and connected to the drive mechanism.

[0092] The air conditioner provided in this application embodiment has all the above-mentioned beneficial effects because it includes the air guide plate of any of the above embodiments, and will not be repeated here.

[0093] In some exemplary embodiments, there are multiple air vents, including a first air vent 151 and a second air vent 152, such as... Figure 19 and Figure 20As shown, the first air vent 151 and the second air vent 152 have different air outlet directions. The first air vent 151 is configured to connect with the air duct 14 to form a first air outlet channel. The second air vent 152 is configured to connect with the air duct 14 to form a second air outlet channel. In other words, when the first air vent 151 is connected to the air duct 14, the air outlet channel formed by their connection is the first air outlet channel. In other words, when the second air vent 152 is connected to the air duct 14, the air outlet channel formed by their connection is the second air outlet channel.

[0094] The first air vent 151 and the second air vent 152 can be air outlets of an air conditioner, or openings inside the air conditioner located upstream of the air outlet. An indoor heat exchanger 3 and a fan 4 can be installed inside the air duct 14. The fan 4 rotates, drawing indoor air into the air duct 14, where it exchanges heat with the indoor heat exchanger 3, and then is discharged into the indoor space through the air outlet channel, thus regulating the temperature of the indoor air.

[0095] In some embodiments, such as Figure 19 and Figure 20 As shown, the first air outlet 151 can be a downwind outlet, discharging air downwards; the second air outlet 152 can be a side outlet, discharging air horizontally. Therefore, the first air outlet mode is the downwind air outlet mode, the second air outlet mode is the downwind air outlet mode, and the third air outlet mode is the dual air outlet mode.

[0096] like Figure 19 and Figure 20 As shown, there are two air guide plates, namely the first air guide plate 21 and the second air guide plate 22. The first air guide plate 21 and the second air guide plate 22 cooperate to control the opening and closing of the first air outlet 151 and the second air outlet 152, so that the air conditioner has: a first air outlet mode in which the first air outlet channel is open and the second air outlet channel is closed; a second air outlet mode in which the first air outlet channel is closed and the second air outlet channel is open; and a third air outlet mode in which both the first air outlet channel and the second air outlet channel are open. The drive mechanism is configured to drive the first air guide plate 21 and the second air guide plate 22 to move relative to the housing.

[0097] In some exemplary embodiments, the second air vent 152 includes a first sub-air vent 1521 and a second sub-air vent 1522 that are interconnected, with the second sub-air vent 1522 located between the first air vent 151 and the first sub-air vent 1521, such as... Figure 19 As shown.

[0098] like Figure 19 and Figure 20 As shown, the first air guide plate 21 is rotatably connected to the housing and is configured to rotate relative to the housing between a first position where the first air vent 151 is closed and the second sub-air vent 1522 is open, a second position where the first air vent 151 and the second sub-air vent 1522 are open, and a third position where the first air vent 151 is open and the second sub-air vent 1522 is closed.

[0099] like Figure 19 and Figure 20 As shown, the second air guide plate 22 is rotatably connected to the housing and is configured to rotate relative to the housing between the fourth position where the first sub-air vent 1521 is closed and the fifth position where the first sub-air vent 1521 is open.

[0100] When the first air guide plate 21 is in the third position and the second air guide plate 22 is in the fourth position, the first air vent 151 is open and the second air vent 152 is closed, and the air conditioner is in the first air outlet mode. At this time, the sealing edges of the first air guide plate 21 and the second air guide plate 22 overlap and seal each other, and the other parts of the edges of the first air guide plate 21 and the second air guide plate 22 overlap and seal with the housing.

[0101] When the first air guide plate 21 is in the first position and the second air guide plate 22 is in the fifth position, the first air outlet 151 is closed and the second air outlet 152 is open, and the air conditioner is in the second air outlet mode. At this time, the circumferential edge of the first air guide plate 21 overlaps and seals with the housing, such as... Figure 19 As shown.

[0102] When the first air guide plate 21 is in the second position and the second air guide plate 22 is in the fifth position, the first air vent 151 opens and the second air vent 152 opens, and the air conditioner is in the third air outlet mode.

[0103] In some exemplary embodiments, such as Figure 19 As shown, the housing includes an outer shell 11, a water receiving tray 12 connected to the outer shell 11, and an air guide support 13 connected to the outer shell 11 and the water receiving tray 12. The air guide support 13 is provided with a second air outlet 152, and the water receiving tray 12 and the air guide support 13 together form a first air outlet 151. The first air guide plate 21 and the second air guide plate 22 are both rotatably connected to the air guide support 13.

[0104] Among them, such as Figure 19 As shown, the water receiving tray 12 can be located inside the outer casing 11 and below the indoor heat exchanger 3, and the water receiving tray 12 can be connected to the bottom of the outer casing 11. The air guide support 13 can be located inside the outer casing 11 and connected to the front of the outer casing 11 and the top of the water receiving tray 12. The water receiving tray 12 can be provided with an air passage opening. One end (lower end) of the air guide support 13 near the water receiving tray 12 can be connected to the water receiving tray 12 and connected to the end of the air passage opening, so that the water receiving tray 12 and the air guide support 13 enclose the first air outlet 151. The lower end of the outer casing 11 can be open, and the casing can also include a cover plate, which covers the open end of the outer casing 11 and is provided with a clearance opening corresponding to and communicating with the first air outlet 151.

[0105] In some exemplary embodiments, such as Figure 22As shown, the stepped portion 26 of the first air guide plate 21 includes a first sealing surface 215 and a first clearance surface 216 that are connected to each other, and the stepped portion 26 of the second air guide plate 22 includes a second sealing surface 225 and a second clearance surface 226 that are connected to each other.

[0106] like Figure 19 and Figure 22 As shown, based on the first air guide plate 21 being located in the third position and the second air guide plate 22 being located in the fourth position, the first sealing surface 215 and the second sealing surface 225 overlap and seal, and there is a first clearance gap 281 between the first clearance surface 216 and the second clearance surface 226.

[0107] This not only achieves the overlapping and sealing of the first air guide plate 21 and the second air guide plate 22, but also helps to avoid friction when the first air guide plate 21 or the second air guide plate 22 rotates after deformation.

[0108] In some exemplary embodiments, such as Figure 22 As shown, the first sealing surface 215 includes a first stepped surface 211 and a third stepped surface 213, and the first clearance surface 216 includes a second stepped surface 212 and a fourth stepped surface 214. The first stepped surface 211, the second stepped surface 212, the third stepped surface 213 and the fourth stepped surface 214 are arranged along the direction from the second foaming space 252 to the first foaming space 251 and are connected by turns in sequence.

[0109] like Figure 22 As shown, the second sealing surface 225 includes a fifth step surface 221 and a seventh step surface 223, and the second clearance surface 226 includes a sixth step surface 222 and an eighth step surface 224. The fifth step surface 221, the sixth step surface 222, the seventh step surface 223, and the eighth step surface 224 are arranged along the direction from the second foaming space 252 to the first foaming space 251 and are connected by turns in sequence.

[0110] like Figure 22 As shown, based on the first air guide plate 21 being located in the third position and the second air guide plate 22 being located in the fourth position, there is a first clearance gap 281 between the first step surface 211 and the fifth step surface 221, the second step surface 212 and the sixth step surface 222 overlap and seal, the third step surface 213 and the seventh step surface 223 have a first clearance gap 281, and the fourth step surface 214 and the eighth step surface 224 overlap and seal.

[0111] In this way, when the first air guide plate 21 and the second air guide plate 22 overlap and seal, a double seal can be achieved, which is beneficial to improving the sealing effect; and there are two first clearance gaps 281, which helps to avoid friction between the first air guide plate 21 and the second air guide plate 22.

[0112] In some exemplary embodiments, the width W1 of the first clearance gap 281 can be greater than 1 mm, which can effectively avoid friction between the first air guide plate 21 and the second air guide plate 22. Of course, the width of the first clearance gap 281 is not limited to the above range and can be adjusted as needed.

[0113] In some exemplary embodiments, the drive mechanism includes a first drive member and a second drive member. The first drive member is tightly fitted with the first shaft hole 2373 of the air guide plate, and the second drive member is loosely fitted with the second shaft hole 2374 of the air guide plate. The housing forms a support carrier for the air guide plate, and the third connecting portion of the air guide plate is rotatably connected to the housing.

[0114] The housing is provided with a positioning shaft 16, which is inserted into the positioning groove 2375 of the air guide plate to limit the axial movement range of the air guide plate relative to the housing.

[0115] like Figure 21 As shown, the positioning groove 2375 has a first end wall 2384 and a second end wall 2385 arranged along the direction from the first connecting portion 2371 of the air guide plate to the second connecting portion 2372. The gap between the positioning shaft 16 and the first end wall 2384 is greater than the gap between the positioning shaft 16 and the second end wall 2385. This helps to prevent the air guide plate from moving too much axially during the drop process, which could cause it to come loose.

[0116] The positioning groove 2375 has a first end wall 2384 and a second end wall 2385 arranged along the direction from the first shaft hole 2373 to the second shaft hole 2374. The gap between the positioning shaft 16 and the first end wall 2384 is greater than the gap between the positioning shaft 16 and the second end wall 2385.

[0117] The gap between the positioning shaft 16 and the first end wall 2384 allows the air guide plate to move closer to the second driving member. The gap between the positioning shaft 16 and the second end wall 2385 allows the air guide plate to move closer to the first driving member. Since the air guide plate is tightly fitted to the first driving member, its movement towards the first driving member should not be too large to prevent impact. However, the air guide plate is loosely fitted to the second driving member, and a certain range of axial movement space is reserved between them. Therefore, the air guide plate can move relatively larger towards the second driving member to prevent jamming. Thus, the gap between the positioning shaft 16 and the first end wall 2384 is larger than the gap between the positioning shaft 16 and the second end wall 2385, resulting in a relatively smaller axial movement of the air guide plate towards the first driving member to avoid impact, and a relatively larger axial movement towards the second driving member to avoid jamming.

[0118] In some exemplary embodiments, such as Figures 23 to 25As shown, the housing has a first sealing protrusion 171 extending along the length of the air guide plate and a second sealing protrusion 172 extending along the width of the air guide plate. The first sealing protrusion 171 is configured to overlap and seal with the portion of the insulation member 24 located at the first strip groove 2521 in the second foaming space 252. The second sealing protrusion 172 is configured to overlap and seal with the portion of the insulation member 24 located at the second strip groove 2522 in the second foaming space 252. This improves the sealing performance between the air guide plate and the housing.

[0119] Based on the air guide plate rotating to the position where it overlaps and seals with the first sealing protrusion 171 (e.g. Figure 23 and Figure 24 As shown, the minimum distance W2 between the first sealing protrusion 171 and the end of the first strip groove 2521 in the width direction is greater than or equal to 2.5mm. This helps to prevent the first sealing protrusion 171 from failing to effectively abut against the portion of the insulation component 24 located at the first strip groove 2521 when the air guide plate deforms, thus affecting the sealing effect. At this time, there can be a second clearance gap 282 between the rotating connection part 237 of the housing and the air guide plate. This helps to prevent friction when the air guide plate rotates relative to the housing when it deforms.

[0120] Based on the air guide plate rotating to the position where it overlaps and seals with the second sealing protrusion 172 (e.g. Figure 25 As shown, the minimum distance W2 between the second sealing protrusion and the end of the second strip groove in the width direction is greater than or equal to 2.5 mm. This helps to prevent the second sealing protrusion 172 from failing to effectively abut against the portion of the insulation component 24 located at the second strip groove 2522 when the air guide plate deforms, thus affecting the sealing effect. At this time, there can be a second clearance gap 282 between the rotating connection part 237 of the housing and the air guide plate. This helps to prevent friction from occurring when the air guide plate rotates relative to the housing when it deforms.

[0121] Of course, W2 is not limited to the above range and can be adjusted as needed.
