Example 1

In the single-drive air deflector assembly of this embodiment, the first rotating arm 2 is a first crank assembly, and the second rotating arm 3 is a second crank assembly.

The direction of this embodiment is referred to in fig. 1, and since fig. 1 is close to the rear view of the single-drive air deflection assembly, the left side of fig. 1 is the "right" of the single-drive air deflection assembly, the right side of fig. 1 is the "left" of the single-drive air deflection assembly, the upper side of fig. 1 is the "upper" of the single-drive air deflection assembly, the lower side of fig. 1 is the "lower" of the single-drive air deflection assembly, the front side of fig. 1 is the "rear" of the single-drive air deflection assembly, and the rear side of fig. 1 is the "front" of the single-drive air deflection assembly. On the basis of this orientation limitation, the single drive air deflection assemblies of this embodiment will be described in detail.

The present embodiment provides a single drive air deflection assembly, referring to fig. 1, comprising an air deflection plate 1, a first crank assembly and a second crank assembly. The air deflector 1 can be rotatably arranged, the first crank rod assembly and the second crank rod assembly are respectively arranged at two opposite end parts of the air deflector 1 in the rotating direction, and the first crank rod assembly and the second crank rod assembly are rotatably connected with the air deflector 1.

Specifically, the left-right direction in fig. 1 is the longitudinal 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, whereby the opposite end portions in the rotation direction of the air guide plate 1 are the upper end portion of the air guide plate 1 and the lower end portion of the air guide plate 1, respectively. In this embodiment, the first crank assembly is disposed at the upper end of the air deflector 1, the second crank assembly is disposed at the lower end of the air deflector 1, and the first crank assembly and the second crank assembly are disposed opposite to each other in the vertical direction and are both rotatably connected to the air deflector 1.

The connection part of the air deflector 1 of the first crank rod assembly is a first rotation center, the connection part of the second crank rod assembly and the air deflector 1 is a second rotation center, the first crank rod assembly can drive the air deflector 1 to rotate around the second rotation center, the second crank rod assembly can drive the air deflector 1 to rotate around the first rotation center, and the first crank rod assembly and the second crank rod assembly intermittently rotate, namely, when the first crank rod assembly rotates, the second crank rod assembly is in a static state, and when the second crank rod assembly rotates, the first crank rod assembly is in a static state. Therefore, the single air deflector assembly intermittently rotates through the first crank rod assembly and the second crank rod assembly, and the rotation centers of the first crank rod assembly and the second crank rod assembly are different, so that the rotation angle range of the air deflector 1 is enlarged, and the swing angle of the air deflector 1 can be adjusted in a large range, so that air deflector 1 with multiple angles can be realized.

In order to ensure the stability of the air deflector 1 in rotation, referring to fig. 1, the air deflector 1 is provided with two groups of first crank rod assemblies and second crank rod assemblies, the two groups of first crank rod assemblies and second crank rod assemblies are uniformly distributed along the length direction of the air deflector 1, and the two groups of first crank rod assemblies and second crank rod assemblies can be respectively arranged in the middle area of the length direction of the air deflector 1 or at two ends of the length direction of the air deflector 1 and are rotatably connected with the air deflector 1. In this embodiment, two sets of first crank rod assemblies and second crank rod assemblies are respectively disposed at two ends of the air deflector 1 in the length direction.

Referring to fig. 2, two opposite ends of the air deflector 1 in the rotation direction are respectively provided with a first connecting shaft 11 and a second connecting shaft 12, one end of the first crank rod assembly, which is close to the air deflector 1, is provided with a first connecting portion 221, the first connecting portion 221 is provided with a first through hole 222 which is matched with the first connecting shaft 11, the first connecting shaft 11 rotatably penetrates through the first through hole 222, one end of the second crank rod assembly, which is close to the air deflector 1, is provided with a second connecting portion 321, the second connecting portion 321 is provided with a second through hole 322 which is matched with the second connecting shaft 12, and the second connecting shaft 12 rotatably penetrates through the second through hole 322, so that the first crank rod assembly and the second crank rod assembly are rotatably connected with the air deflector 1.

Specifically, the first connecting shaft 11 is disposed at the upper end of the air deflector 1 and extends along the length direction of the air deflector 1, the first through hole 222 penetrates the first connecting portion 221 along the length direction of the air deflector 1, and the first crank rod assembly is rotatably sleeved on the first connecting shaft 11 through the first through hole 222, so as to realize rotatable connection of the first crank rod assembly and the air deflector 1.

The second connecting shaft 12 is arranged at the lower end of the air deflector 1 and extends along the length direction of the air deflector 1, the second through hole 322 penetrates through the second connecting portion 321 along the length direction of the air deflector 1, and the second crank rod assembly is rotatably sleeved on the second connecting shaft 12 through the second through hole 322 so as to realize rotatable connection of the second crank rod assembly and the air deflector 1.

Although the first crank assembly and the second crank assembly are rotatably connected to the air deflector 1, this does not mean that the first crank assembly and the second crank assembly are always in a state of rotating relative to the air deflector 1, and the first crank assembly and/or the second crank assembly may be stationary relative to the air deflector 1, rotate relative to each other, or rotate synchronously. For example, in the initial state, the first crank lever assembly, the second crank lever assembly and the air deflector 1 are all in the stationary state. When the first crank rod assembly rotates around the second rotation center, the second crank rod assembly rotates relative to the air deflector 1, and the first crank rod assembly rotates synchronously with the air deflector 1. When the second crank rod assembly rotates around the first rotation center, the first crank rod assembly rotates relative to the air deflector 1, and the second crank rod assembly rotates synchronously with the air deflector 1.

Referring to fig. 1, the intermittent rotation of the first crank assembly and the second crank assembly is realized by a driving member 4, and the driving member 4 intermittently drives the first crank assembly and the second crank assembly to rotate and drives the air deflector 1 to synchronously rotate.

Referring to fig. 2, the driving member 4 includes a motor 41, a first rotating portion 211 is disposed at an end of the first crank assembly away from the air deflector 1, a second rotating portion 311 is disposed at an end of the second crank assembly away from the air deflector 1, and the motor 41 intermittently drives the first rotating portion 211 and the second rotating portion 311 to rotate, so that the first crank assembly and the second crank assembly intermittently rotate.

Intermittent driving of the first rotating portion 211 and the second rotating portion 311 by the motor 41 is achieved by 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 rotating part 211 and the second rotating part 311 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 disposed in contact with the first rotating portion 211, the second friction plate 46 is disposed in contact with the second rotating portion 311, and the motor 41 intermittently drives the first friction plate 45 to pre-press the first rotating portion 211 and the second friction plate 46 to pre-press the second rotating portion 311 so that the first rotating portion 211 and the second rotating portion 311 intermittently rotate.

The 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, and when the pretightening force of the first friction plate 45 to the first rotating part 211 is enough to drive the first rotating part 211 to rotate, the first rotating part 211 drives the first crank rod assembly to rotate, so that the air deflector 1 is driven to synchronously rotate. At this time, the pretightening force between the second friction plate 46 and the second rotating portion 311 is insufficient to drive the second rotating portion 311 to rotate, and the second crank assembly is in a stationary state.

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, and when the pretightening force of the second friction plate 46 to the second rotating part 311 is enough to drive the second rotating part 311 to rotate, the second rotating part 311 drives the second crank rod assembly to rotate, so that the air deflector 1 is driven to synchronously rotate. At this time, the pretightening force between the first friction plate 45 and the first rotating portion 211 is insufficient to drive the first rotating portion 211 to rotate, and the first crank assembly is in a stationary state.

Referring to the specific structure of the driving member 4 in fig. 2, a first groove 441 and a second groove 442 are formed on the radial peripheral side of the output shaft 44, a first through hole 451 adapted to the first groove 441 is formed in the first friction plate 45 along the axial direction of the output shaft 44, and the first friction plate 45 is fixedly connected with the output shaft 44 through 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 matching 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 through the fixed connection between the second groove 442 and the second through hole 461.

Specifically, the output shaft 44 has a cylindrical structure, and the first groove 441 and the second groove 442 are both provided with a flat surface, so that the outer circumferences of the first groove 441 and the second groove 442 are in a structure of connecting the circular arc surface and the flat surface, so that the first groove 441 and the first through hole 451 do not rotate relatively, and the second groove 442 and the second through hole 461 do not rotate relatively, so that the first friction plate 45 and the second friction plate 46 are fixedly connected with the output shaft 44.

The first friction plate 45 is disposed on a side of the first rotating portion 211 away from the second rotating portion 311, the second friction plate 46 is disposed on a side of the second rotating portion 311 away from the first rotating portion 211, the blocking portion 4311 is protruded on a radial circumferential side of the output shaft 44, the blocking portion 4311 is disposed between the first rotating portion 211 and the second rotating portion 311, and the first friction plate 45, the first rotating portion 211, the blocking portion 4311, the second rotating portion 311 and the second friction plate 45 are sequentially abutted, so that the first friction plate 45, the first rotating portion 211, the second rotating portion 311 and the second friction plate 45 are not relatively displaced in an axial direction of the output shaft 44.

In the present embodiment, the first friction plate 45 and the second friction plate 46 are elastic members, and when the first friction plate 45 abuts against the first rotating portion 211 and the second friction plate 46 abuts against the second rotating portion 311, the first friction plate 45 and the second friction plate 46 are elastically deformed, so that the first friction plate 45 has a pre-tightening force on the first rotating portion 211 and the second friction plate 46 has a pre-tightening force on the second rotating portion 311, and thus there is a possibility that the first friction plate 45 drives the first rotating portion 211 to rotate synchronously, and a possibility that the second friction plate 46 drives the second rotating portion 311 to rotate synchronously.

And whether the pre-tightening force of the first friction plate 45 to the first rotating portion 211 is enough to drive the first rotating portion 211 to rotate, and whether the pre-tightening force of the second friction plate 46 to the second rotating portion 311 is enough to drive the second rotating portion 311 to rotate are achieved through the following structure.

Referring to fig. 2, the first crank rod assembly includes a first crank 21 and a first sliding rod 22, wherein a first rotating portion 211 is disposed at one end of the first crank 21 away from the air deflector 1, a first opening is disposed at one end of the first crank 21 close to the air deflector 1, a first cavity is disposed inside the first crank 21 along an extending direction of the first crank, the first cavity is communicated with the first opening, and the first sliding rod 22 is disposed in the first cavity and extends out of the first opening and can slide reciprocally along the extending direction of the first cavity. The first connecting portion 221 is disposed at one end of the first sliding rod 22 near the air deflector 1, the first connecting portion 221 is provided with a first through hole 222 adapted to the first connecting shaft 11, and the first connecting shaft 11 rotatably penetrates through the first through hole 222, so that the first sliding rod 22 is rotatably connected with the air deflector 1.

The second crank rod assembly comprises a second crank 31 and a second sliding rod 32, one end, far away from the air deflector 1, of the second crank 31 is provided with a second rotating part 311, one end, close to the air deflector 1, of the second crank 31 is provided with a second opening, a second cavity is formed in the second crank 31 along the extending direction of the second crank, the second cavity is communicated with the second opening, and the second sliding rod 32 is arranged in the second cavity and extends out of the second opening and can slide back and forth along the extending direction of the second cavity. The second sliding rod 32 is provided with a second connecting part 321 near one end of the air deflector 1, the second connecting part 321 is provided with a second through hole 322 matched with the second connecting shaft 12, and the second connecting shaft 12 is rotatably arranged in the second through hole 322 in a penetrating way, so that the second sliding rod 32 is rotatably connected with the air deflector 1.

One side of the first crank rod assembly, which is far away from the second crank rod assembly, is provided with a first resisting piece, one side of the second crank rod assembly, which is far away from the first crank rod assembly, is provided with a second resisting piece, and in an initial state, the first crank rod assembly is abutted against the first resisting piece, and the second crank rod assembly is abutted against the second resisting piece.

The first retaining member may be disposed at any position on a side of the first crank rod assembly away from the second crank rod assembly, and the structure of the first retaining member is not limited. The second resisting member may be disposed at any position of a side of the second crank rod assembly away from the first crank rod assembly, and the structure of the second resisting member is not limited. Only the first resisting piece and the second resisting piece are convenient to set and can play a role in resisting.

On the basis, the working principle of the air deflector assembly of the embodiment is as follows:

under the condition that the first crank rod assembly, the second crank rod assembly and the air deflector 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, the first friction plate 45 has pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has pretightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a tendency to rotate clockwise. However, since the second crank rod assembly abuts against the second resisting member, the abutting force is greater than the pretightening force of the second friction plate 46 on the second rotating portion 311, so that the second friction plate 46 is insufficient to drive the second rotating portion 311 to rotate, and the second crank rod assembly is in a stationary state. The first crank rod assembly does not have the blocking of the abutting structure, the pretightening force of the first friction plate 45 to the first rotating part 211 is enough to drive the first rotating part 211 to rotate, so that the first crank rod assembly is driven to rotate around the second rotation center through the first rotating part 211, the first sliding rod 22 slides away from the first crank 21, and the air deflector 1 is driven to synchronously rotate until the maximum angle is reached.

On the basis of the above state, the motor 41 drives the output shaft 44 to reversely rotate and drives the first friction plate 45 and the second friction plate 46 to synchronously rotate, and the first friction plate 45 has a pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pretightening force on the second rotating part 311 due to elastic deformation, so that both the first crank rod assembly and the second crank rod assembly have a counterclockwise rotation trend. However, since the second friction plate 46 accumulates the pretightening force of the second rotating portion 311 during the clockwise rotation, the second rotating portion 311 has a certain invisible force during the clockwise rotation, and thus the second friction plate 46 rotates reversely to cancel the invisible force generated during the clockwise rotation until the reverse rotation is performed by the same angle, so as to cancel the invisible force, and during this process, the second rotating portion 311 and the second crank assembly are stationary. The first crank rod assembly does not have the abutting structure and the blocking of the invisible force, the pretightening force of the first friction plate 45 to the first rotating part 211 is enough to drive the first rotating part 211 to rotate, so that the first crank rod assembly is driven by the first rotating part 211 to reversely rotate around the second rotating center, the first sliding rod 22 slides close to the first crank 21, and the air deflector 1 is driven to synchronously rotate until the initial state is returned.

Conversely, under the condition that the first crank rod assembly, the second crank rod assembly and the air deflector 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate anticlockwise and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, the first friction plate 45 has a pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pretightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a tendency to rotate anticlockwise. However, since the first crank rod assembly abuts against the first resisting member, the abutting force is greater than the pretightening force of the first friction plate 45 on the first rotating portion 211, so that the first friction plate 45 is insufficient to drive the first rotating portion 211 to rotate, and the first crank rod assembly is in a static state. The second crank rod assembly does not have the blocking of the abutting structure, the pretightening force of the second friction plate 46 to the second rotating part 311 is enough to drive the second rotating part 311 to rotate, so that the second crank rod assembly is driven to rotate around the first rotation center through the second rotating part 311, the second sliding rod 32 slides away from the second crank 31, and the air deflector 1 is driven to synchronously rotate until the maximum angle is reached.

On the basis of the state, the motor 41 drives the output shaft 44 to reversely rotate and drives the first friction plate 45 and the second friction plate 46 to synchronously rotate, the first friction plate 45 has pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has pretightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a clockwise rotating trend. However, since the first friction plate 45 accumulates the pretightening force of the first rotating portion 211 during the counterclockwise rotation, the first rotating portion 211 has a certain anti-clockwise invisible force, and thus the first friction plate 45 rotates reversely to cancel the invisible force generated by the counterclockwise rotation until the reverse rotation is completed by the same angle, so that the invisible force is cancelled, and the first rotating portion 211 and the first crank assembly are stationary during the process. The second crank rod assembly does not have the abutting structure and the blocking of the invisible force, the pretightening force of the second friction plate 46 to the second rotating part 311 is enough to drive the second rotating part 311 to rotate, so that the second crank rod assembly is driven to reversely rotate around the first rotating center through the second rotating part 311, the second sliding rod 32 slides close to the second crank 31, and the air deflector 1 is driven to synchronously rotate until the initial state is returned.

The rotation principle that the single-drive air deflector assembly rotates around two rotation centers in the embodiment can enlarge the rotation angle range of the air deflector 1, so that the swing angle of the air deflector 1 can be adjusted in a large range, and the air deflector 1 with various angles can be realized.

In addition to the single-drive air deflection assemblies described above, the present embodiment also provides an air conditioner, and referring to fig. 3 to 4, the air conditioner includes a housing 5, and an air outlet 51 and an air inlet 52 are provided on the housing 5.

In the present embodiment, the air inlet 52 is disposed at the top of the housing 5, the air outlet 51 is disposed at the lower portion of the front side wall of the housing 5, and the air outlet 51 is disposed obliquely. The inclined structure of the air outlet 51 is: the front side wall of the housing 5 extends beyond the front end of the bottom plate of the housing 5, and the air outlet 51 is inclined from the bottom end of the front side wall of the housing 5 to the front end of the bottom plate of the housing 6.

The air deflector assembly is disposed at the air outlet 51 of the housing 5, specifically, the air deflector 1 is obliquely disposed at the air outlet 51 to close the air outlet 51, and the air deflector 1 can rotate at the air outlet 51. The first crank rod assembly and the second crank rod assembly are arranged on the shell 5, specifically, the driving piece 4, the first crank rod assembly and the second crank rod assembly are all arranged in the shell 5, and the first crank rod assembly and the second crank rod assembly penetrate out of the shell 5 to be rotatably connected with the air deflector 1. In this embodiment, the first resisting member is a housing 5 of the first crank rod assembly above the air outlet 51, and the second resisting member is a housing 5 of the second crank rod assembly below the air outlet 51.

On the basis, the air conditioner of the embodiment can realize the following air outlet modes:

the first crank rod assembly, the second crank rod assembly and the air deflector 1 are in an initial state, and the air conditioner is in a closed state.

Under the condition that the first crank rod assembly, the second crank rod assembly and the air deflector 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, the first friction plate 45 has pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has pretightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a tendency to rotate clockwise. At this time, since the lower portion of the second crank rod assembly abuts against the housing 6, the abutting force is greater than the pretightening force of the second friction plate 46 on the second rotating portion 311, so that the second friction plate 46 is insufficient to drive the second rotating portion 311 to rotate, and the second crank rod assembly is in a stationary state. The first crank rod assembly is not blocked by the abutting structure, the pretightening force of the first friction plate 45 to the first rotating part 211 is enough to drive the first rotating part 211 to rotate, so that the first crank rod assembly is driven to rotate around the second rotation center through the first rotating part 211, the first sliding rod 22 slides away from the first crank 21, and the air deflector 1 is driven to synchronously rotate clockwise for a certain angle. When the air deflector 1 forms an acute angle with the bottom plate of the shell 6, the air conditioner outputs air at an upward angle. When the air deflector 1 rotates to be parallel to the bottom plate of the shell 6, the air conditioner horizontally discharges air.

On the basis of the above state, the motor 41 drives the output shaft 44 to reversely rotate and drives the first friction plate 45 and the second friction plate 46 to synchronously rotate, and the first friction plate 45 has a pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pretightening force on the second rotating part 311 due to elastic deformation, so that both the first crank rod assembly and the second crank rod assembly have a counterclockwise rotation trend. However, since the second friction plate 46 accumulates the pretightening force of the second rotating portion 311 during the clockwise rotation, the second rotating portion 311 has a certain invisible force during the clockwise rotation, and thus the second friction plate 46 rotates reversely to cancel the invisible force generated during the clockwise rotation until the reverse rotation is performed by the same angle, so as to cancel the invisible force, and during this process, the second rotating portion 311 and the second crank assembly are stationary. The first crank rod assembly does not have the abutting structure and the blocking of the invisible force, the pretightening force of the first friction plate 45 to the first rotating part 211 is enough to drive the first rotating part 211 to rotate, so that the first crank rod assembly is driven by the first rotating part 211 to reversely rotate around the second rotating center, the first sliding rod 22 slides close to the first crank 21 and drives the air deflector 1 to synchronously rotate until the air conditioner returns to the initial state, and the air conditioner is closed.

Conversely, under the condition that the first crank rod assembly, the second crank rod assembly and the air deflector 1 are all in the initial state, the motor 41 drives the output shaft 44 to rotate anticlockwise and drives the first friction plate 45 and the second friction plate 46 to rotate synchronously, the first friction plate 45 has a pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has a pretightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a tendency to rotate anticlockwise. However, since the first crank rod assembly abuts against the upper housing 6, the abutting force is greater than the pre-tightening force of the first friction plate 45 on the first rotating portion 211, so that the first friction plate 45 is insufficient to drive the first rotating portion 211 to rotate, and the first crank rod assembly is in a stationary state. The second crank rod assembly is not blocked by the abutting structure, the pretightening force of the second friction plate 46 to the second rotating part 311 is enough to drive the second rotating part 311 to rotate, so that the second crank rod assembly is driven to rotate around the first rotation center through the second rotating part 311, the second sliding rod 32 slides away from the second crank 31, and the air deflector 1 is driven to synchronously rotate anticlockwise by a certain angle. When the air deflector 1 and the front side wall of the shell 6 form an included angle with an acute angle, the air conditioner outputs air at a downward angle, and when the air deflector 1 rotates to be parallel to the front side wall of the shell 6, the air conditioner outputs air vertically.

On the basis of the state, the motor 41 drives the output shaft 44 to reversely rotate and drives the first friction plate 45 and the second friction plate 46 to synchronously rotate, the first friction plate 45 has pretightening force on the first rotating part 211 due to elastic deformation, and the second friction plate 46 has pretightening force on the second rotating part 311 due to elastic deformation, so that the first crank rod assembly and the second crank rod assembly have a clockwise rotating trend. However, since the first friction plate 45 accumulates the pretightening force of the first rotating portion 211 during the counterclockwise rotation, the first rotating portion 211 has a certain anti-clockwise invisible force, and thus the first friction plate 45 rotates reversely to cancel the invisible force generated by the counterclockwise rotation until the reverse rotation is completed by the same angle, so that the invisible force is cancelled, and the first rotating portion 211 and the first crank assembly are stationary during the process. The second crank rod assembly does not have the abutting structure and the blocking of the invisible force, the pretightening force of the second friction plate 46 to the second rotating part 311 is enough to drive the second rotating part 311 to rotate, so that the second crank rod assembly is driven to reversely rotate around the first rotating center through the second rotating part 311, the second sliding rod 32 slides close to the second crank 31, and the air deflector 1 is driven to synchronously rotate until the air conditioner returns to the initial state, and the air conditioner is closed.

From this, the air conditioner of this embodiment rotates with two rotation centers through aviation baffle 1, and the rotation angle scope of aviation baffle 1 relative casing 5 grow to can adjust the swing angle of aviation baffle 1 relative casing 5 on a large scale, thereby realize horizontal air-out, vertical air-out and angle air-out, make the air-out direction of air conditioner have the variety, satisfy the user demand.
