[0034] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] The direction of this embodiment is Figure 1 For reference, due to Figure 1 Close to the rear view of the deflector assembly, so Figure 1 The left side is the "right" of the air guide assembly. Figure 1 The right side is the "left" of the air guide assembly. Figure 1 The upper side of is the "upper" of the air guide assembly. Figure 1 The lower side of is the "lower" of the air guide assembly. Figure 1 The front side is the "rear" of the air deflector assembly. Figure 1 The rear side is the "front" of the air deflector assembly. Based on this orientation definition, the air deflector assembly of this embodiment is described in detail below.

[0038] This embodiment provides a wind deflector assembly, see Figure 1, comprising an air guide plate 1, a first rotating shaft 2 and a second rotating shaft 3. The air guide plate 1 is rotatably arranged, the first rotating shaft 2 and the second rotating shaft 3 are respectively arranged at two opposite ends of the air guide plate 1 in the rotating direction, and the first rotating shaft 2 and the second rotating shaft 3 are both rotatably connected to the air guide plate 1.

[0039] Specifically, Figure 1 The left-right direction is the length direction of the air guide plate 1, and the rotation of the air guide plate 1 is performed in a plane formed by the up-down direction and the front-back direction, so that the two opposite ends of the air guide plate 1 in the rotation direction are the upper end of the air guide plate 1 and the lower end of the air guide plate 1. In this embodiment, the first rotating shaft 2 is provided at the upper end of the air guide plate 1, and the second rotating shaft 3 is provided at the lower end of the air guide plate 1. The first rotating shaft 2 and the second rotating shaft 3 are relatively arranged in the up-down direction, and are both rotatably connected to the air guide plate 1.

[0040] Among them, the connection point of the first rotating shaft 2 and the air guide plate 1 is the first rotation center, and the connection point of the second rotating shaft 3 and the air guide plate 1 is the second rotation center. The first rotating shaft 2 can drive the air guide plate 1 to rotate around the second rotation center, and the second rotating shaft 3 can drive the air guide plate 1 to rotate around the first rotation center, and the first rotating shaft 2 and the second rotating shaft 3 rotate intermittently, that is, when the first rotating shaft 2 rotates, the second rotating shaft 3 is in a stationary state, and when the second rotating shaft 3 rotates, the first rotating shaft 2 is in a stationary state. Therefore, the air guide plate assembly of the present invention is intermittently rotated by the first rotating shaft 2 and the second rotating shaft 3, and the rotation centers of the two are different, which expands the rotation angle range of the air guide plate 1, so that the swing angle of the air guide plate 1 can be adjusted in a wide range to achieve wind guide of various angles of the air guide plate 1.

[0041] The working principle of the air guide plate assembly of this embodiment is:

[0042] Under the condition that the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in the initial state, the second rotating shaft 3 is kept stationary, the first rotating shaft 2 rotates around the second rotating center, and drives the air guide plate 1 to rotate downward synchronously. During the rotation of the first rotating shaft 2, the rotation angle of the first rotating shaft 2 can be controlled at any time to adjust the rotation angle of the air guide plate 1 until the first rotating shaft 2 rotates to the maximum angle, at which time the air guide plate 1 rotates to the maximum angle in this direction. The air guide plate 1 can be returned to the initial state by controlling the first rotating shaft 2 to rotate in the opposite direction to the initial state.

[0043] Under the condition that the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in the initial state, the first rotating shaft 2 is kept stationary, the second rotating shaft 3 rotates around the first rotating center, and drives the air guide plate 1 to rotate upward synchronously. During the rotation of the second rotating shaft 3, the rotation angle of the second rotating shaft 3 can be controlled at any time to adjust the rotation angle of the air guide plate 1 until the second rotating shaft 3 rotates to the maximum angle, at which time the air guide plate 1 rotates to the maximum angle in this direction. The air guide plate 1 can be returned to the initial state by controlling the second rotating shaft 3 to rotate in the opposite direction to the initial state.

[0044] In order to ensure the stability of the rotation of the wind deflector 1, refer to Figure 1 The air guide plate 1 is provided with two sets of first rotating shafts 2 and second rotating shafts 3. The two sets of first rotating shafts 2 and second rotating shafts 3 are respectively arranged at two ends of the length direction of the air guide plate 1, and are both rotatably connected to the air guide plate 1.

[0045] See also Figure 3 A first connecting shaft 11 and a second connecting shaft 12 are respectively provided at the opposite two ends in the rotation direction of the air guide plate 1, and a first through hole 22 adapted to the first connecting shaft 11 is provided at one end of the first rotating shaft 2 close to the air guide plate 1, and the first connecting shaft 11 is rotatably inserted into the first through hole 22, and a second through hole 32 adapted to the second connecting shaft 12 is provided at one end of the second rotating shaft 3 close to the air guide plate 1, and the second connecting shaft 12 is rotatably inserted into the second through hole 32, thereby realizing that the first rotating shaft 2 and the second rotating shaft 3 are rotatably connected to the air guide plate 1.

[0046] Specifically, the first connecting shaft 11 is arranged at the upper end of the wind guide plate 1 and extends along the length direction of the wind guide plate 1. The first through hole 22 penetrates one end of the first rotating shaft 2 close to the wind guide plate 1 along the length direction of the wind guide plate 1. The first rotating shaft 2 is rotatably mounted on the first connecting shaft 11 through the first through hole 22 to realize the rotatable connection between the first rotating shaft 2 and the wind guide plate 1.

[0047] The second connecting shaft 12 is arranged at the lower end of the wind guide plate 1 and extends along the length direction of the wind guide plate 1. The second through hole 32 penetrates one end of the second rotating shaft 3 close to the wind guide plate 1 along the length direction of the wind guide plate 1. The second rotating shaft 3 is rotatably mounted on the second connecting shaft 12 through the second through hole 32 to realize the rotatable connection between the second rotating shaft 3 and the wind guide plate 1.

[0048] It should be noted that, although the first rotating shaft 2 and the second rotating shaft 3 are both rotatably connected to the air guide plate 1, it does not mean that the first rotating shaft 2 and the second rotating shaft 3 are always in a state of relative rotation with the air guide plate 1. The first rotating shaft 2 and / or the second rotating shaft 3 and the air guide plate 1 can be relatively stationary, relatively rotating, or synchronously rotating. For example, in the initial state, the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in a stationary state. When the first rotating shaft 2 rotates around the second rotation center, the second rotating shaft 3 rotates relative to the air guide plate 1, and the first rotating shaft 2 rotates synchronously with the air guide plate 1. When the second rotating shaft 3 rotates around the first rotation center, the first rotating shaft 2 rotates relative to the air guide plate 1, and the second rotating shaft 3 rotates synchronously with the air guide plate 1.

[0049] See also Figure 2 The intermittent rotation of the first rotating shaft 2 and the second rotating shaft 3 is realized by the driving component 4. The driving component 4 intermittently drives the first rotating shaft 2 and the second rotating shaft 3 to rotate, and drives the air guide plate 1 to rotate synchronously.

[0050] See also Figure 3 The driving assembly 4 includes a motor 41, a first gear 42 and a second gear 43. The first rotating shaft 2 is provided with a first rack 21 meshing with the first gear 42, and the second rotating shaft 3 is provided with a second rack 31 meshing with the second gear 43. The motor 41 intermittently drives the first gear 42 and the second gear 43 to rotate, so that the first rotating shaft 2 and the second rotating shaft 3 rotate intermittently.

[0051] The working principle is as follows: when the motor 41 drives the first gear 42 to rotate, the first rotating shaft 2 is driven to rotate through the meshing of the first gear 42 and the first rack 21, thereby driving the wind guide plate 1 to rotate synchronously. At this time, the second gear 43 and the second rotating shaft 3 are in a stationary state.

[0052] When the motor 41 drives the second gear 43 to rotate, the second rotating shaft 3 is driven to rotate through the meshing of the second gear 43 and the second rack 31, thereby driving the wind guide plate 1 to rotate synchronously. At this time, the first gear 42 and the first rotating shaft 2 are in a stationary state.

[0053] The motor 41 intermittently drives the first gear 42 and the second gear 43 to rotate through the output shaft 44, the first friction plate 45 and the second friction plate 46. The output shaft 44 is connected to the output end of the motor 41, the first gear 42 and the second gear 43 are rotatably sleeved on the output shaft 44, and the first friction plate 45 and the second friction plate 46 are fixedly sleeved on the output shaft 44. The first friction plate 45 is arranged to abut against the first gear 42, and the second friction plate 46 is arranged to abut against the second gear 43. The motor 41 intermittently drives the first friction plate 45 to pre-tighten the first gear 42 and the second friction plate 46 to pre-tighten the second gear 43, so that the first gear 42 and the second gear 43 rotate intermittently.

[0054] Its working principle is as follows: the motor 41 drives the output shaft 44 to rotate, and synchronously drives the first friction plate 45 and the second friction plate 46 to rotate. When the pre-tightening force of the first friction plate 45 on the first gear 42 is sufficient to drive the first gear 42 to rotate, the first rotating shaft 2 is driven to rotate through the meshing of the first gear 42 and the first rack 21, thereby driving the wind guide plate 1 to rotate synchronously. At this time, the pre-tightening force of the second friction plate 46 and the second gear 43 is insufficient to drive the second gear 43 to rotate, and the second rotating shaft 3 is in a stationary state.

[0055] The motor 41 drives the output shaft 44 to rotate, and synchronously drives the first friction plate 45 and the second friction plate 46 to rotate. When the pre-tightening force of the second friction plate 46 on the second gear 43 is sufficient to drive the second gear 43 to rotate, the second rotating shaft 3 is driven to rotate through the meshing of the second gear 43 and the second rack 31, thereby driving the wind guide plate 1 to rotate synchronously. At this time, the pre-tightening force of the first friction plate 45 and the first gear 42 is insufficient to drive the first gear 42 to rotate, and the first rotating shaft 2 is in a stationary state.

[0056] See also Figure 3 The specific structure of the middle drive assembly 4 is that the radial circumferential side of the output shaft 44 is provided with a first groove 441 and a second groove 442, and the first friction plate 45 is provided with a first through hole 451 matched with the first groove 441 along the axial direction of the output shaft 44, and the first friction plate 45 is fixedly connected with the output shaft 44 by the fixed connection between the first groove 441 and the first through hole 451. The second friction plate 46 is provided with a second through hole 461 matched with the second groove 442 along the axial direction of the output shaft 44, and the second friction plate 46 is fixedly connected with the output shaft 44 by the fixed connection between the second groove 442 and the second through hole 461.

[0057] Specifically, the output shaft 44 is a cylindrical structure, and the first groove 441 and the second groove 442 are both provided with a platform surface, so that the outer periphery of the first groove 441 and the second groove 442 is a structure in which an arc surface and a platform surface are connected, so that the first groove 441 and the first through hole 451 do not rotate relative to each other, and the second groove 442 and the second through hole 461 do not rotate relative to each other, so that the first friction plate 45 and the second friction plate 46 are fixedly connected to the output shaft 44.

[0058] The first friction plate 45 is arranged on the side of the first gear 42 away from the second gear 43, and the second friction plate 46 is arranged on the side of the second gear 43 away from the first gear 42. A blocking portion 443 is convexly provided on the radial circumferential side of the output shaft 44, and the blocking portion 443 is arranged between the first gear 42 and the second gear 43. The first friction plate 45, the first gear 42, the blocking portion 443, the second gear 43 and the second friction plate 45 are abutted in sequence, so that the first friction plate 45, the first gear 42, the second gear 43 and the second friction plate 45 do not have relative displacement in the axial direction of the output shaft 44.

[0059] The first friction plate 45 and the second friction plate 46 of the present embodiment are both elastic parts. When the first friction plate 45 abuts against the first gear 42 and the second friction plate 46 abuts against the second gear 43, the first friction plate 45 and the second friction plate 46 are both elastically deformed so that the first friction plate 45 has a pre-tightening force on the first gear 42 and the second friction plate 46 has a pre-tightening force on the second gear 43, so that there is a possibility that the first friction plate 45 drives the first gear 42 to rotate synchronously, and there is a possibility that the second friction plate 46 drives the second gear 43 to rotate synchronously.

[0060] Whether the pre-tightening force of the first friction plate 45 on the first gear 42 is sufficient to drive the first gear 42 to rotate, and whether the pre-tightening force of the second friction plate 46 on the second gear 43 is sufficient to drive the second gear 43 to rotate, is achieved through the accommodating box 5.

[0061] See also Figure 2 and Figure 4 The first rotating shaft 2, the second rotating shaft 3, the first gear 42, the second gear 43, the output shaft 44, the first friction plate 45 and the second friction plate 46 are all arranged in the accommodating box 5, and the first rotating shaft 2 and the second rotating shaft 3 pass through the accommodating box 5 and are rotatably connected to the air guide plate 1, and the ends of the first rotating shaft 2 and the second rotating shaft 3 away from the air guide plate 1 both abut against the inner wall of the accommodating box 5.

[0062] On this basis, the working principle of the air guide plate assembly of this embodiment is:

[0063] Under the condition that the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate clockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate clockwise. However, since the end of the second rotating shaft 3 away from the air guide plate 1 abuts against the inner wall of the accommodating box 5, the abutting force is greater than the pre-tightening force of the second friction plate 46 on the second gear 43, so that the second friction plate 46 is insufficient to drive the second gear 43 to rotate, so that the second rotating shaft 3 is in a stationary state. Since the first rotating shaft 2 has no abutment structure to block it, the pre-tightening force of the first friction plate 45 on the first gear 42 is sufficient to drive the first gear 42 to rotate, thereby driving the first rotating shaft 2 to rotate around the second rotation center through the engagement of the first gear 42 with the first rack 21, and driving the air guide plate 1 to rotate synchronously until it rotates to the maximum angle.

[0064] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate counterclockwise. However, due to the accumulation of the pre-tightening force of the second friction plate 46 on the second gear 43 during the above clockwise rotation, the second gear 43 has a certain invisible force for clockwise rotation, so the second friction plate 46 rotates in the opposite direction to offset the invisible force generated by the above clockwise rotation, until the reverse rotation is the same angle to complete the offset of the invisible force, and in this process, the second gear 43 and the second rotating shaft 3 are stationary. Since the first rotating shaft 2 has no abutment structure and invisible force obstruction, the pre-tightening force of the first friction plate 45 on the first gear 42 is sufficient to drive the first gear 42 to rotate, thereby driving the first rotating shaft 2 to rotate in the opposite direction around the second rotation center through the engagement of the first gear 42 with the first rack 21, and driving the air guide plate 1 to rotate synchronously until it returns to the initial state.

[0065] On the contrary, when the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate counterclockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate counterclockwise. However, since the end of the first rotating shaft 2 away from the air guide plate 1 abuts against the inner wall of the accommodating box 5, the abutting force is greater than the pre-tightening force of the first friction plate 45 on the first gear 42, so that the first friction plate 45 is insufficient to drive the first gear 42 to rotate, so that the first rotating shaft 2 is in a stationary state. Since the second rotating shaft 3 has no abutment structure to block it, the pre-tightening force of the second friction plate 46 on the second gear 43 is sufficient to drive the second gear 43 to rotate, thereby driving the second rotating shaft 3 to rotate around the first rotation center through the engagement of the second gear 43 with the second rack 31, and driving the air guide plate 1 to rotate synchronously until it rotates to the maximum angle.

[0066] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate clockwise. However, due to the accumulation of the pre-tightening force of the first friction plate 45 on the first gear 42 during the above counterclockwise rotation, the first gear 42 has a certain invisible force for counterclockwise rotation, therefore, the first friction plate 45 rotates in the opposite direction to offset the invisible force generated by the above counterclockwise rotation, until the reverse rotation is the same angle, so that the invisible force is completely offset, and in this process, the first gear 42 and the first rotating shaft 2 are stationary. Since the second rotating shaft 3 has no abutment structure and invisible force obstruction, the pre-tightening force of the second friction plate 46 on the second gear 43 is sufficient to drive the second gear 43 to rotate, thereby driving the second rotating shaft 3 to rotate in the opposite direction around the first rotation center through the engagement of the second gear 43 with the second rack 31, and driving the air guide plate 1 to rotate synchronously until it returns to the initial state.

[0067] The above is the rotation principle of the air guide plate assembly of this embodiment around two rotation centers, which can expand the rotation angle range of the air guide plate 1, thereby being able to adjust the swing angle of the air guide plate 1 over a wide range to achieve air guiding of the air guide plate 1 at various angles.

[0068] It should be noted that in order to ensure the rotation trajectory of the first rotating axis 2 and the second rotating axis 3, a first guide rail 51 and a second guide rail 52 are provided in the accommodating box 5. The first guide rail 51 is adapted to the first rotating axis 2, and the second guide rail 52 is adapted to the second rotating axis 3, so that the first rotating axis 2 can rotate along the first guide rail 51, and the second rotating axis 3 can rotate along the second guide rail 52, thereby avoiding trajectory deviation of the first rotating axis 2 and the second rotating axis 3 during rotation.

[0069] Specifically, the accommodating box 5 includes a first box body 53 and a second box body 54 that are detachably connected, the first guide rail 51 is arranged in the first box body 53, and the second guide rail 52 is arranged in the second box body 54 to avoid mutual interference between the rotation of the first rotating shaft 2 and the second rotating shaft 3.

[0070] The detachable connection between the first box body 53 and the second box body 54 can be a common snap connection, bolt connection, etc. in the prior art, which will not be listed here one by one.

[0071] In addition to the above-mentioned air guide plate assembly, this embodiment also provides an air conditioner, see Figures 5 to 7 The air conditioner comprises a shell 6 , a heat exchanger 8 and a fan 7 are arranged in the shell 6 , and an air outlet 61 and an air inlet 62 are arranged on the shell 6 .

[0072] In this embodiment, the air inlet 62 is arranged at the top of the housing 6, the air outlet 61 is arranged at the lower part of the front side wall of the housing 6, and the air outlet 61 is arranged obliquely. The inclined structure of the air outlet 61 is as follows: the front side wall of the housing 6 exceeds the front end of the bottom plate of the housing 6, and the air outlet 61 is arranged obliquely from the bottom end of the front side wall of the housing 6 to the front end of the bottom plate of the housing 6.

[0073] The aforementioned air guide plate assembly is arranged at the air outlet 61 of the housing 6, specifically, the air guide plate 1 is arranged at the air outlet 61 at an angle to close the air outlet 61, and the air guide plate 1 can rotate at the air outlet 61. The first rotating shaft 2 and the second rotating shaft 3 are arranged on the housing 6, specifically, the accommodating box 5, the driving assembly 4, the first rotating shaft 2 and the second rotating shaft 3 are all arranged in the housing 6, and the first rotating shaft 2 and the second rotating shaft 3 pass through the housing 6 and are rotatably connected to the air guide plate 1.

[0074] On this basis, the air conditioner of this embodiment can achieve the following air outlet modes:

[0075] The first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are in an initial state, and the air conditioner is in a closed state.

[0076] Under the condition that the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate clockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 have a tendency to rotate clockwise. At this time, since the end of the second rotating shaft 3 away from the air guide plate 1 abuts against the inner wall of the accommodating box 5, the abutting force is greater than the pre-tightening force of the second friction plate 46 on the second gear 43, so that the second friction plate 46 is not enough to drive the second gear 43 to rotate, so that the second rotating shaft 3 is in a stationary state. Since the first rotating shaft 2 has no abutment structure to block it, the pre-tightening force of the first friction plate 45 on the first gear 42 is sufficient to drive the first gear 42 to rotate, so that the first rotating shaft 2 is driven to rotate around the second rotation center through the meshing of the first gear 42 and the first rack 21, and the air guide plate 1 is driven to rotate clockwise synchronously by a certain angle. When the air guide plate 1 and the bottom plate of the housing 6 are at an acute angle, the air conditioner blows air upward. When the air guide plate 1 rotates to be parallel to the bottom plate of the housing 6, the air conditioner blows air horizontally.

[0077] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate counterclockwise. However, due to the accumulation of the pre-tightening force of the second friction plate 46 on the second gear 43 during the above clockwise rotation, the second gear 43 has a certain invisible force for clockwise rotation, so the second friction plate 46 rotates in the opposite direction to offset the invisible force generated by the above clockwise rotation, until the reverse rotation is the same angle to complete the offset of the invisible force, and in this process, the second gear 43 and the second rotating shaft 3 are stationary. Since the first rotating shaft 2 has no abutment structure and invisible force obstruction, the pre-tightening force of the first friction plate 45 on the first gear 42 is sufficient to drive the first gear 42 to rotate, thereby driving the first rotating shaft 2 to rotate in the opposite direction around the second rotation center through the engagement of the first gear 42 with the first rack 21, and driving the air guide plate 1 to rotate synchronously until it returns to the initial state to turn off the air conditioner.

[0078] On the contrary, when the first rotating shaft 2, the second rotating shaft 3 and the air guide plate 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate counterclockwise, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate counterclockwise. However, since the end of the first rotating shaft 2 away from the air guide plate 1 abuts against the inner wall of the accommodating box 5, the abutting force is greater than the pre-tightening force of the first friction plate 45 on the first gear 42, so that the first friction plate 45 is insufficient to drive the first gear 42 to rotate, so that the first rotating shaft 2 is in a stationary state. Since the second rotating shaft 3 is not blocked by the abutment structure, the pre-tightening force of the second friction plate 46 on the second gear 43 is sufficient to drive the second gear 43 to rotate, thereby driving the second rotating shaft 3 to rotate around the first rotating center through the meshing of the second gear 43 and the second rack 31, and driving the air guide plate 1 to rotate counterclockwise by a certain angle synchronously. When the air guide plate 1 and the front side wall of the shell 6 have an acute angle, the air conditioner discharges air at a downward angle, and when the air guide plate 1 rotates to be parallel to the front side wall of the shell 6, the air conditioner discharges air vertically.

[0079] Based on the above state, the motor 41 drives the output shaft 44 to rotate in the opposite direction, and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, and the first friction plate 45 has a pre-tightening force on the first gear 42 due to elastic deformation, and the second friction plate 46 has a pre-tightening force on the second gear 43 due to elastic deformation, so that the first rotating shaft 2 and the second rotating shaft 3 both have a tendency to rotate clockwise. However, due to the accumulation of the pre-tightening force of the first friction plate 45 on the first gear 42 during the above counterclockwise rotation, the first gear 42 has a certain invisible force for counterclockwise rotation, therefore, the first friction plate 45 rotates in the opposite direction to offset the invisible force generated by the above counterclockwise rotation, until the reverse rotation is the same angle, so that the invisible force is completely offset, and in this process, the first gear 42 and the first rotating shaft 2 are stationary. Since the second rotating shaft 3 has no abutment structure and invisible force obstruction, the pre-tightening force of the second friction plate 46 on the second gear 43 is sufficient to drive the second gear 43 to rotate, thereby driving the second rotating shaft 3 to rotate in the opposite direction around the first rotation center through the engagement of the second gear 43 with the second rack 31, and driving the air guide plate 1 to rotate synchronously until it returns to the initial state to turn off the air conditioner.

[0080] Therefore, the air conditioner of this embodiment rotates with two rotation centers through the air guide plate 1, and the rotation angle range of the air guide plate 1 relative to the shell 6 becomes larger, so that the swing angle of the air guide plate 1 relative to the shell 6 can be adjusted in a wide range, thereby realizing horizontal air outlet, vertical air outlet and angle air outlet, so that the air outlet direction of the air conditioner is diverse to meet user needs.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
