Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air guide plate structure and an air conditioner. Background Art

[0002] In order to prevent condensation from occurring on the air guide plate assembly of the air conditioner, the air conditioner is generally provided with a double-layer panel, for example, including an inner lining plate and an outer air guide plate, so that there is a gap between the inner lining plate and the outer air guide plate, thereby preventing the condensation water generated inside the air conditioner from penetrating to the outer surface of the outer air guide plate.

[0003] However, one drawback of the related art is that when the inner lining and outer air deflector are connected, a noticeable gap is created at the joint of the rotating shaft structure of the corresponding air deflector assembly. Therefore, a retaining rib is required to prevent the user from seeing the interior of the air conditioner through this gap, which would affect the overall aesthetics. However, the presence of the retaining rib makes the air deflector assembly prone to abnormal noise during operation. Summary of the Invention

[0004] The problem solved by the present invention is the technical problem that the air guide plate assembly is prone to abnormal noise during operation due to the presence of baffle ribs.

[0005] In order to solve the above problems, the present invention provides an air guide plate structure, comprising: an air guide outer plate, one end of which is provided with a first rotating shaft portion; an inner lining plate, which is cooperatively connected with the air guide outer plate, and one end of the inner lining plate is provided with a second rotating shaft portion; wherein, the first rotating shaft portion and the second rotating shaft portion cooperate to form a first contact surface and a second contact surface that are relatively arranged; a protruding structure, which is clamped between the first contact surface and the second contact surface; wherein, the protruding structure protrudes relative to the surface of either the air guide outer plate or the inner lining plate toward the other of the either one, so as to prevent the first contact surface from contacting the second contact surface and generating abnormal noise.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by providing a protruding structure between the first contact surface and the second contact surface to prevent the first contact surface and the second contact surface from contacting each other, that is, by reducing the contact area between the first contact surface and the second contact surface to avoid abnormal noise during the rotation of the air guide plate structure driven by the rotating shaft.

[0007] In one example of the present invention, the protruding structure is provided on the first contact surface; and / or the protruding structure is provided on the second contact surface.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: combined with the structural characteristics of the inner lining plate, specifically, the inner lining plate is lighter and thinner than the air guide outer plate, that is, in the process of assembling the first rotating shaft part and the second rotating shaft part, by setting the protruding structure on the second contact surface, the structural strength of the second rotating shaft part corresponding to the second contact surface position is enhanced.

[0009] In one embodiment of the present invention, the first rotating shaft portion and the second rotating shaft portion are nested and matched.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the first rotating shaft portion and the second rotating shaft portion are closely matched to form an arc-shaped rotating shaft space, thereby avoiding looseness between the first rotating shaft portion and the second rotating shaft portion during the process of the rotating shaft driving the air guide plate structure to rotate, and causing loose matching between the rotating shaft and the first rotating shaft portion and the second rotating shaft portion.

[0011] In one example of the present invention, the first rotating shaft portion and the second rotating shaft portion cooperate to form a rotating shaft space; a second baffle is provided at one end of the second rotating shaft portion close to the first rotating shaft portion, and the second baffle extends toward the direction of the first rotating shaft portion; the second baffle is located on a side of the first rotating shaft portion close to the rotating shaft space; wherein, the protruding structure is clamped between the second baffle and the first rotating shaft portion; and / or, a first baffle is provided at one end of the first rotating shaft portion close to the second rotating shaft portion, and the first baffle extends toward the direction of the second rotating shaft portion; the first baffle is located on a side of the second rotating shaft portion away from the rotating shaft space; wherein, the protruding structure is clamped between the first baffle and the second rotating shaft portion.

[0012] Compared with the existing technology, the technical effects achieved by adopting this technical solution are: on the one hand, it ensures the neatness and beauty of the appearance of the air guide plate structure, and avoids the situation where the second baffle is placed outside, which, although it can also play the role of blocking the fitting gap, makes the second baffle exposed to the user's line of sight, giving the user a sudden feeling, that is, the outer surface of the shaft sleeve composed of the first shaft part and the second shaft part is not smooth, forming a fault feeling, thereby affecting the overall appearance of the air conditioner; on the other hand, the second baffle is built into the shaft space, so that the shaft space is fully utilized. Since there is a protruding structure clamped between the second baffle and the corresponding inner wall of the first shaft part to prevent the first contact surface and the second contact surface from contacting each other, the contact area between the second baffle and the first shaft part is reduced, thereby avoiding the occurrence of abnormal noise.

[0013] In one embodiment of the present invention, there are multiple protruding structures; wherein, multiple protruding structures are arranged at intervals along the axial direction of the first rotating shaft portion; or multiple protruding structures are arranged continuously along the axial direction of the first rotating shaft portion.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are: on the one hand, the manner of arranging the protruding structures at intervals reduces the contact area between the first contact surface and the second contact surface, thereby reducing the loudness of the abnormal sound; in addition, the manner of arranging the protruding structures at intervals can also reduce the material cost expenditure caused by continuously arranging the protruding structures along the axis of the first rotating shaft portion; on the other hand, for example, the protruding structures can be arranged in a continuous manner, combined with the structural characteristics of the air guide plate structure, that is, it is made of plastic, and since the lengths of the first rotating shaft portion and the second rotating shaft portion along their axial directions correspond to the lengths of the air outlet on the air conditioner, that is, considering that the length of the air outlet is long, if the protruding structures are arranged at intervals, when the spacing between adjacent protruding structures is too large, it is easy for the first rotating shaft portion or the second rotating shaft portion corresponding to the spacing to deform. Because the deformation is too large, the first contact surface and the second contact surface corresponding to the position are in direct contact, thereby causing abnormal noise to occur during the rotation of the air guide plate structure driven by the rotating shaft.

[0015] In one embodiment of the present invention, the protruding structure is integrally formed with the air guide outer panel; and / or the protruding structure is integrally formed with the inner lining panel.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: reducing the processing technology and simplifying the processing procedures.

[0017] In one embodiment of the present invention, the inner lining plate includes: a lining plate body; a connecting portion for connecting the lining plate body and the second rotating shaft portion; and an anti-shrinkage structure provided on the connecting portion.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the anti-shrinkage structure at the connection part to enhance the structural strength of the connection part, combined with the processing process of producing the formed inner lining plate, that is, the thickness of the inner lining plate corresponding to the connection part is thinner and is prone to shrinkage, so the anti-shrinkage structure is set to reduce the degree of shrinkage.

[0019] In one embodiment of the present invention, the anti-shrinkage structure and the protruding structure are provided separately.

[0020] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by separating the anti-shrinkage structure and the protruding structure, the glue reduction at the corresponding setting positions of the two can be avoided.

[0021] In one example of the present invention, the protruding structure includes: a protruding body, connected to the surface of any one of the wind guide outer plate and the inner lining plate; a protruding end, connected to the protruding body, and the protruding end is located between the first contact surface and the second contact surface; wherein the protruding end and the first contact surface are in point-to-surface contact or line-to-surface contact; or the protruding end and the second contact surface are in point-to-surface contact or line-to-surface contact.

[0022] Compared with the existing technology, the technical effects achieved by adopting this technical solution are: for example, the first contact surface and the second contact surface are transformed from a surface-to-surface contact mode to a point-to-surface or line-to-surface contact mode through the structural characteristics of the protruding end, thereby avoiding the phenomenon of abnormal noise caused by adjusting and rotating the air guide plate structure when the air guide plate structure is applied to the air conditioner, thereby improving the user experience.

[0023] On the other hand, the present invention also provides an air conditioner, comprising: an air guide plate structure as described in any of the above examples; a middle frame provided with an air outlet; wherein the air guide plate structure is provided at a position of the middle frame corresponding to the air outlet.

[0024] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect corresponding to any of the above technical solutions, which will not be repeated here.

[0025] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0026] (1) A protruding structure is provided between the first contact surface and the second contact surface to prevent the first contact surface and the second contact surface from contacting each other, that is, by reducing the contact area between the first contact surface and the second contact surface to avoid abnormal noise during the rotation of the air guide plate structure driven by the rotating shaft;

[0027] (2) On the one hand, it ensures the neatness and beauty of the appearance of the air guide plate structure, and avoids the situation that when the second baffle is placed outside, although it can also play the role of covering the fitting gap, the second baffle is exposed to the user's sight, giving the user a sudden feeling, that is, the outer surface of the shaft sleeve composed of the first shaft part and the second shaft part is not smooth, forming a fault feeling, thereby affecting the overall appearance of the air conditioner; on the other hand, the second baffle is built into the shaft space, so that the shaft space is fully utilized. Due to the presence of the protruding structure sandwiched between the second baffle and the corresponding inner wall of the first shaft part, the first contact surface and the second contact surface are prevented from contacting each other, thereby reducing the contact area between the second baffle and the first shaft part, thereby avoiding the occurrence of abnormal noise;

[0028] (3) By setting an anti-shrinkage structure at the connection part to enhance the structural strength of the connection part, combined with the processing process of producing the molded inner lining plate, that is, the thickness of the inner lining plate corresponding to the connection part is thinner and is prone to shrinkage, the anti-shrinkage structure is set to reduce the degree of shrinkage.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] Example 1:

[0042] See also Figure 1, which is a structural diagram of a wind deflector structure 100 provided in the first embodiment of the present invention. Figure 2-7 The air deflector structure 100 includes, for example, an air deflector outer plate 10, an inner lining plate 20, and a protruding structure 30. A first rotation axis portion 11 is provided at one end of the air deflector outer plate 10; the inner lining plate 20 is coupled to the air deflector outer plate 10, and a second rotation axis portion 21 is provided at one end of the inner lining plate 20; the first rotation axis portion 11 and the second rotation axis portion 21 cooperate to form a first contact surface 13 and a second contact surface 23 that are oppositely disposed; the protruding structure 30 is sandwiched between the first contact surface 13 and the second contact surface 23; the protruding structure 30 protrudes from the surface of either the air deflector outer plate 10 or the inner lining plate 20 toward the other, so as to prevent the first contact surface 13 and the second contact surface 23 from contacting and generating abnormal noise.

[0043] In one specific embodiment, the air deflector structure 100 is used, for example, in a wall-mounted air conditioner. Specifically, the air deflector structure 100 is mounted to the air outlet 201 of the wall-mounted air conditioner 200. Thus, the air deflector outer panel 10 is exposed to the indoor environment, allowing the user to directly see it. At this time, when the air deflector structure 100 covers the air outlet 201, the inner lining panel 20 is sandwiched between the air deflector outer panel 10 and the middle frame 210. Furthermore, the shaft space 101 formed by the first shaft portion 11 and the second shaft portion 21 is used to mount the shaft. This allows the shaft to rotate the air deflector structure 100 under the drive of the drive motor to adjust the direction of the air outlet 201. For example, the rotating shaft controls the wind guide plate structure 100 to swing up and down in the vertical direction, so that the wind blown out from the air outlet 201 is also adjusted accordingly. Specifically, in the process of adjusting the wind guide plate structure 100 to swing downward in the vertical direction, the wind blown out from the air outlet 201 is directed to be blown out in the downward direction.

[0044] Among them, since the guide outer plate and the inner lining plate 20 are connected together by splicing, a fitting gap is formed between the two. Specifically, the fitting gap formed at the splicing of the first rotating shaft portion 11 and the second rotating shaft portion 21 is easy to expose the fitting gap to the user during the adjustment of the rotating air guide plate structure 100. On the one hand, when the user observes the air conditioner 200 from a close distance, the exposure of the fitting gap reduces the aesthetic appearance of the air conditioner 200, thereby reducing the user's evaluation and user experience of the air conditioner 200; on the other hand, it causes part of the air to be blown out from the fitting gap, that is, reduces the air volume blown out of the corresponding air outlet 201, thereby reducing the use efficiency of the air conditioner 200 and further reducing the user's user experience.

[0045] Therefore, in order to solve the above problem, a shielding structure is extended from any mating end surface of the first rotating shaft portion 11 or the second rotating shaft portion 21 in the direction toward the other, so as to shield the mating gap formed by the mating of the first rotating shaft portion 11 and the second rotating shaft portion 21. Specifically, the shielding structure is, for example, a long strip of plate, which is provided on either the first rotating shaft portion 11 or the second rotating shaft portion 21, and when it extends toward the other of the either one, a first contact surface 13 and a second contact surface 23 that are arranged oppositely are formed between the shielding structure and the corresponding side surface of either the first rotating shaft portion 11 or the second rotating shaft portion 21. In order to ensure that the shielding effect is optimal, the shielding structure is extended so as to fit the corresponding side surface of the corresponding first rotating shaft portion 11 or the second rotating shaft portion 21, so that the first contact surface 13 and the second contact surface 23 fit together. Therefore, due to the large contact area between the first rotating shaft portion 11, the second rotating shaft portion 21 and the shielding member, when the rotating shaft drives the air guide plate structure 100 to rotate, the first rotating shaft portion 11, the second rotating shaft portion 21 and the shielding member are squeezed against each other, causing abnormal noise, thereby affecting the user experience.

[0046] Therefore, in combination with the content of the present technical solution, a protruding structure 30 is provided between the first contact surface 13 and the second contact surface 23 to prevent the first contact surface 13 and the second contact surface 23 from contacting each other, that is, by reducing the contact area between the first contact surface 13 and the second contact surface 23, abnormal noise is avoided during the rotation of the air guide plate structure 100 driven by the rotating shaft. In addition, in combination with the content of the above-mentioned specific example, on the one hand, the shielding structure also ensures that the fitting gap formed by the first rotating shaft portion 11 and the second rotating shaft portion 21 is shielded, preventing it from being exposed to the user's field of vision and affecting the overall appearance of the air conditioner 200, thereby reducing the user's user experience; on the other hand, the shielding structure improves the use efficiency of the air conditioner 200, that is, reducing the amount of air blown out of the fitting gap so that as much air as possible is blown out from the air outlet 201 of the air conditioner 200.

[0047] Preferably, the protruding structure 30 is provided on the first contact surface 13 ; and / or the protruding structure 30 is provided on the second contact surface 23 .

[0048] In a specific embodiment, the protruding structure 30 can be provided on the second contact surface 23, that is, the protruding structure 30 can be provided on the second rotating shaft portion 21 and protrude toward the first contact surface 13. Therefore, when the rotating shaft drives the air deflector structure 100 to swing, the protruding structure 30 provided between the first contact surface 13 and the second contact surface 23 limits contact between the first contact surface 13 and the second contact surface 23, that is, the minimum distance maintained between the first contact surface 13 and the second contact surface 23 is greater than zero. Since the first rotating shaft portion 11 and the second rotating shaft portion 21 are both made of plastic and have a certain amount of deformation, in order to further prevent the first rotating shaft portion 11 and the second rotating shaft portion 21 from being squeezed against each other and causing at least part of the first contact surface 13 and the second contact surface 23 to contact, the protruding height of the protruding structure 30 can be adjusted to increase the distance formed when the first contact surface 13 and the second contact surface 23 abut against the protruding structure 30, thereby effectively preventing the first contact surface 13 and the second contact surface 23 from contacting. In addition, the protruding structure 30 can also enhance the structural strength of the second rotating shaft portion 21 corresponding to the second contact surface 23 .

[0049] Of course, for example, the protruding structure 30 can also be provided on the first contact surface 13, protruding toward the second contact surface 23. The specific situation is the same as that described in the above specific example, and will not be repeated here.

[0050] Of course, the protruding structures 30 can also be provided on both the first contact surface 13 and the second contact surface 23. Specifically, for example, the protruding structures 30 provided on the first contact surface 13 can be referred to as first protruding structures 30, and the protruding structures 30 provided on the second contact surface 23 can be referred to as second protruding structures 30. The first protruding structures 30 and the second protruding structures 30 can be arranged in an interlaced manner, or each protruding structure 30 can be arranged to abut against the end of each second protruding structure 30 in a one-to-one correspondence, thereby further increasing the distance between the first contact surface 13 and the second contact surface 23.

[0051] Preferably, the first rotating shaft portion 11 and the second rotating shaft portion 21 are nested and matched. Specifically, the first rotating shaft portion 11 is a first semi-circular arc structure, and a matching slot is provided in the first semi-circular arc structure; in contrast, the second rotating shaft portion 21 is a second semi-circular arc structure, and a matching clip is provided therein to match and connect with the matching slot. Therefore, when the first rotating shaft portion 11 and the second rotating shaft portion 21 are nested and matched, the matching clip is connected to the matching slot accordingly, so that the first rotating shaft portion 11 and the second rotating shaft portion 21 are tightly matched to form an arc-shaped rotating shaft space 101, thereby preventing the first rotating shaft portion 11 and the second rotating shaft portion 21 from becoming loose during the process of the rotating shaft driving the air guide plate structure 100 to rotate, and preventing the rotating shaft from loosely matching with the first rotating shaft portion 11 and the second rotating shaft portion 21.

[0052] Preferably, the first rotating shaft portion 11 and the second rotating shaft portion 21 cooperate to form a rotating shaft space 101; a second baffle 24 is provided at one end of the second rotating shaft portion 21 close to the first rotating shaft portion 11, and the second baffle 24 extends toward the direction of the first rotating shaft portion 11. In addition, the second baffle 24 is located on a side of the first rotating shaft portion 11 close to the rotating shaft space 101, wherein the protruding structure 30 is clamped between the second baffle 24 and the first rotating shaft portion 11; and / or, a first baffle is provided at one end of the first rotating shaft portion 11 close to the second rotating shaft portion 21, and the first baffle extends toward the direction of the second rotating shaft portion 21; and the first baffle is located on a side of the second rotating shaft away from the rotating shaft space 101, wherein the protruding structure 30 is clamped between the first baffle and the second rotating shaft portion 21.

[0053] In a specific example, when a second baffle 24 is provided at one end of the second rotating shaft portion 21 close to the first rotating shaft portion 11, since the second baffle 24 is located on the side of the first rotating shaft portion 11 close to the rotating shaft space 101, on the one hand, the appearance of the air guide plate structure 100 is ensured to be neat and beautiful, and when the second baffle 24 is placed outside, although it can also play the role of covering the fitting gap, the second baffle 24 is exposed to the user's line of sight, giving the user an abrupt feeling, that is, the outer surface of the rotating shaft sleeve composed of the first rotating shaft portion 11 and the second rotating shaft portion 21 is not smooth, forming a fault feeling, thereby affecting the overall appearance of the air conditioner 200; on the other hand, the second baffle 24 is built into the rotating shaft space 101, so that the rotating shaft space 101 is fully utilized. Since there is a protruding structure 30 sandwiched between the second baffle 24 and the corresponding inner wall of the first rotating shaft portion 11, the first contact surface 13 and the second contact surface 23 are prevented from contacting each other, thereby reducing the contact area between the second baffle 24 and the first rotating shaft portion 11, thereby avoiding the occurrence of abnormal noise.

[0054] More specifically, the end of the first rotating shaft portion 11 away from the air guide outer plate 10 is recorded as the first end, and the end of the second rotating shaft portion 21 away from the inner lining plate 20 is recorded as the second end. The first end and the second end abut against each other, and the second baffle 24 is arranged at the second end so that an "L"-shaped structure is formed by the second end and the second baffle 24.

[0055] In another specific example, a first baffle may be provided on the first contact surface 13. Similarly, the first baffle and the first end are combined to form an "L"-shaped structure. The specific content is similar to the above specific example and will not be repeated here.

[0056] Preferably, there are multiple protruding structures 30 , wherein the protruding structures 30 are arranged at intervals along the axial direction of the first rotating shaft portion 11 ; or multiple protruding structures 30 are arranged continuously along the axial direction of the first rotating shaft portion 11 .

[0057] In a specific embodiment, when multiple protruding structures 30 are arranged at intervals, on the one hand, compared with continuous arrangement, the contact area between the first contact surface 13 and the second contact surface 23 is reduced by arranging the protruding structures 30, thereby reducing the loudness of the abnormal sound; in addition, the material cost expenditure caused by the continuous arrangement of the protruding structures 30 along the axis of the first rotating shaft portion 11 can be reduced by arranging them at intervals, wherein, for example, adjacent protruding structures 30 can be arranged at equal intervals to make it more beautiful and reduce the difficulty of production; on the other hand, for example, the protruding structures 30 can be arranged in a continuous manner, combined with the structural characteristics of the air guide plate structure 100, that is, it is made of plastic, and because the first rotating shaft portion 1 1 and the length of the second rotating shaft portion 21 along the axial direction thereof corresponds to the length of the air outlet 201 on the air conditioner 200. That is, considering that the length of the air outlet 201 is relatively long, if the protruding structures 30 are arranged at intervals, when the spacing between adjacent protruding structures 30 is too large, it is easy for the first rotating shaft portion 11 or the second rotating shaft portion 21 corresponding to the spacing to deform. Because the deformation is too large, the first contact surface 13 and the second contact surface 23 corresponding to the position are in direct contact, thereby causing abnormal noise to occur during the rotation of the air guide plate structure 100 driven by the rotating shaft. Therefore, by continuously arranging the protruding structures 30, the first contact surface 13 and the second contact surface 23 can achieve a stable contact area through the protruding structures 30.

[0058] Preferably, the protruding structure 30 is integrally formed with the air guide outer panel 10; and / or the protruding structure 30 is integrally formed with the inner lining panel 20, thereby reducing the number of processing steps and simplifying the processing procedures. For example, the protruding structure 30 can be integrally formed with the air guide outer panel 10, or of course, the protruding structure 30 can also be integrally formed with the inner lining panel 20; or, alternatively, the protruding structure 30 can be provided on the air guide outer panel 10 and the inner lining panel 20 respectively, and the protruding structure 30 can be integrally formed with the air guide outer panel 10, or the protruding structure 30 can be integrally formed with the inner lining panel 20, further simplifying the processing steps and making the overall production more efficient.

[0059] Preferably, the inner lining plate 20 includes, for example, a lining plate body 22, a connecting portion 25, and an anti-shrinkage structure 40. Specifically, the connecting portion 25 is sandwiched between the second rotating shaft and the lining plate body 22, and is used to connect the lining plate body 22 to the second rotating shaft portion 21; the anti-shrinkage structure 40 is provided on the connecting portion 25.

[0060] In a specific embodiment, the anti-shrinkage structure 40 is, for example, provided on a side of the inner lining plate 20 close to the wind guide outer plate 10, that is, the anti-shrinkage structure 40 is sandwiched between the inner lining plate 20 and the wind guide outer plate 10. The anti-shrinkage structure 40 is, for example, in the shape of a triangular rib and is arranged at the connection portion 25 to enhance the structural strength of the connection portion 25. In combination with the actual processing process of the inner lining plate 20, there is a large curvature change between the lining plate body 22 and the second rotating shaft portion 21, that is, the connection portion 25 is a transition arc plate, which is used to transitionally connect the corresponding end arcs of the lining plate body 22 and the second rotating shaft portion 21 to avoid large stress. Commonly, the thickness at this location is thinner, so shrinkage is prone to occur at this location. Therefore, by providing the anti-shrinkage structure 40, the degree of shrinkage can be reduced and the structural strength of this location can be improved.

[0061] Furthermore, the shrink-proof structure 40 is separately provided from the protruding structure 30. By separating the shrink-proof structure 40 from the protruding structure 30, the glue reduction at the corresponding arrangement positions of the two structures is avoided.

[0062] Preferably, the protruding structure 30 includes, for example, a protruding body and a protruding end. The protruding body is connected to the surface of either the air deflector outer panel 10 or the inner lining panel 20; the protruding end is connected to the protruding body and is located between the first contact surface 13 and the second contact surface 23. The contact between the protruding end and the first contact surface 13 is point-to-surface contact or line-to-surface contact; or the contact between the protruding end and the second end surface is point-to-surface contact or line-to-surface contact.

[0063] In a specific embodiment, the protruding end is, for example, an arc end surface, and when the second baffle 24 is disposed on the second rotating shaft portion 21, the arc end surface and the first contact surface 13 of the first rotating shaft portion 11 are in point-to-surface contact. Of course, the first rotating shaft portion 11 is a semi-circular arc structure, and in order to reduce the distance between the protruding end and the first contact surface 13, the radius corresponding to the arc end surface can be made smaller than the radius corresponding to the first rotating shaft portion 11. Of course, the greater the difference between the radius corresponding to the arc end surface and the radius of the first rotating shaft portion 11, the smaller the contact area between the protruding end and the first rotating shaft portion 11. For example, the protruding end can also have a convex hull structure or a pointed tip structure, which will not be described in detail here.

[0064] In another specific embodiment, the protruding end can be in the shape of a long triangular prism, so that the tip surface of the triangular prism contacts the first contact surface 13 of the first rotating shaft portion 11, that is, the contact between the protruding end and the first contact surface 13 is in the form of line and surface, thereby achieving the purpose of reducing the contact area, and further avoiding abnormal noise due to excessive contact area between the protruding end and the first rotating shaft portion 11 during the rotation of the air guide plate structure 100.

[0065] Example 2:

[0066] See also Figure 8 , which is a schematic structural diagram of an air conditioner 200 provided in a second embodiment of the present invention. The air conditioner 200 includes, for example, a middle frame 210 and the air deflector structure 100 described in the first embodiment. The middle frame 210 is provided with an air outlet 201, and the air deflector structure 100 is provided at a position on the middle frame 210 corresponding to the air outlet 201.
