[0043] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] The present disclosure provides an air conditioner. The air conditioner is a large guide plate type air conditioner, which can completely close the air outlet when the air deflector 50 of the air conditioner is in a closed state, and there is no gap between the air deflector 50 and the air outlet. Moreover, during the air supply process, the air deflector 50 first extends out of the air conditioner and then rotates to guide the air. In this way, the air deflector 50 is far away from the air outlet, and the air flow blown out of the air conditioner has small wind resistance, which can reduce the noise generated at the air deflector 50 during the air supply process. At the same time, compared with the air deflector 50 rotating at the air outlet to supply air, the air deflector 50 rotating outside the air outlet can supply air in a larger angle and a larger range, thereby improving the cooling or heating effect of the air conditioner. Alternatively, the air conditioner provided by the present disclosure can also be a cabinet type air conditioner or a duct type air conditioner.

[0045] In some embodiments, the air conditioner comprises the following movement mechanism for the air deflector 50.

[0046] Alternatively, the movement mechanism is arranged on both sides of the air deflector 50, and the movement mechanisms on both sides drive the air deflector 50 to move simultaneously. The following movement mechanism can drive the air deflector 50 to extend out of the air outlet to a first preset position, and then drive the air deflector 50 to rotate. The structure and working process of the movement mechanism are described in detail below.

[0047] The present disclosure also provides a movement mechanism for the air deflector 50, as shown in Figures 1 to 12 .

[0048] In some embodiments, the movement mechanism for the air deflector 50 comprises a driving element 10, a first connecting rod 20, a second connecting rod 30 and a track plate 40. The driving element 10 is provided with a first transmission shaft 121. The first connecting rod 20 is provided with a through slot 21. One end of the first connecting rod 20 is rotationally connected with the air deflector 50. The first transmission shaft 121 is slidingly arranged in the through slot 21. One end of the second connecting rod 30 is rotationally connected with the air deflector 50. The track plate 40 is provided with a track portion for limiting the movement trajectories of the first connecting rod 20 and the second connecting rod 30. The driving element 10 drives the first connecting rod 20 and the second connecting rod 30 to move under the limitation of the track portion through the sliding of the first transmission shaft 121 in the through slot 21, so that the air deflector 50 is first extended out of the air outlet to a first preset position and then rotated. A limiting mechanism is arranged between the first connecting rod 20 and the second connecting rod 30, and the limiting mechanism is used for preventing the second connecting rod 30 from shaking during the movement of the air deflector 50.

[0049] In the above movement mechanism, only one end of the second connecting rod 30 is limitingly connected with the air deflector 50. If the second connecting rod 30 is manually pushed during the movement of the air deflector 50, the second connecting rod 30 will shake up and down. The reliability of the second connecting rod 30 is relatively low. Moreover, the shaking of the second connecting rod 30 will also affect the normal movement of the air deflector 50, and the reliability of the entire movement mechanism is reduced.

[0050] In the movement mechanism for the air deflector 50 provided by the embodiments of the present disclosure, the limiting mechanism is arranged between the first connecting rod 20 and the second connecting rod 30, so that the position of the second connecting rod 30 can be limited, the shaking of the second connecting rod 30 during the movement of the air deflector 50 is avoided, and the reliability of the connecting rods and the entire movement mechanism is improved.

[0051] It can be understood that the driving force for the movement of the first connecting rod 20 comes from the driving element 10. The driving element 10 provides the driving force for the movement of the first connecting rod 20 through the sliding of the first transmission shaft 121 in the through slot 21. One end of each of the first connecting rod 20 and the second connecting rod 30 is connected with the air deflector 50, and then the driving force is transmitted to the second connecting rod 30 through the connecting point between the air deflector 50 and the second connecting rod 30, so as to drive the second connecting rod 30 to move. The first connecting rod 20 and the second connecting rod 30 drive the air deflector 50 to be first extended out of the air outlet to the first preset position under the limitation of the track plate 40, and then drive the air deflector 50 to rotate. In this way, one driving element 10 can drive the connecting rod assembly to move, and then drive the air deflector 50 to be extended out of the air outlet and then rotated to guide the air. The cooperation relationship of the movement mechanism is close, and the structure is simple. At the same time, the air deflector 50 can be extended out of the air conditioner and rotated to guide the air at a large angle, so as to expand the air supply range of the air conditioner.

[0052] Optionally, the limiting mechanism comprises a limiting column 36 and a V-shaped groove 22, the limiting column 36 is arranged on the second connecting rod 30, the V-shaped groove 22 is arranged on the first connecting rod 20, and the limiting column 36 is slidingly arranged in the V-shaped groove 22; wherein, in the process of movement of the air deflector 50, the limiting column 36 moves in the V-shaped groove 22 to limit the position of the second connecting rod 30.

[0053] One end of the second connecting rod 30 is rotationally connected with the air deflector 50, and the limiting column 36 of the second connecting rod 30 is arranged in the V-shaped groove 22, so that the second connecting rod 30 has two positioning positions and the position of the second connecting rod 30 can be limited. No matter where the air deflector 50 moves to, the limiting column 36 is always in the V-shaped groove 22, so that the user cannot manually move the second connecting rod 30, and the reliability of the second connecting rod 30 is improved.

[0054] Optionally, the second connecting rod 30 has a first plate surface opposite to the first connecting rod 20, and the limiting column 36 is arranged on the first plate surface and located at the upper portion of the second connecting rod 30.

[0055] Optionally, the first connecting rod 20 has a limiting plate surface opposite to the second connecting rod 30, and the V-shaped groove 22 is arranged at the middle portion of the limiting plate surface.

[0056] When the air deflector 50 is in a closed state, the first connecting rod 20 and the second connecting rod 30 in the movement mechanism of the embodiment are in a partially abutting state. The second connecting rod 30 has a first plate surface opposite to the first connecting rod 20, and the first connecting rod 20 has a limiting plate surface opposite to the second connecting rod 30. The limiting column 36 is located at the upper portion of the first plate surface of the second connecting rod 30, and the V-shaped groove 22 is located at the middle portion of the limiting plate surface of the first connecting rod 20, that is, the middle and lower portions of the first connecting rod 20 abut against the second connecting rod 30. Moreover, in the process of movement of the air deflector 50, the limiting column 36 is always located in the V-shaped groove 22, and the upper end of the second connecting rod 30 is always kept in a limiting state, so that the shaking of the second connecting rod 30 is avoided.

[0057] Optionally, the V-shaped groove 22 comprises a first positioning groove 221 and a second positioning groove 222 which are merged, the first positioning groove 221 and the second positioning groove 222 are both linear, the first positioning groove 221 and the second positioning groove 222 have the same starting end and the same end which extends in different directions; in the closed state of the air deflector 50, the limiting column 36 is located at the merging position of the first positioning groove 221 and the second positioning groove 222; in the process of upward opening of the air deflector 50 from the closed state, the limiting column 36 slides from the merging position to the end of the first positioning groove 221; in the process of downward opening of the air deflector 50 from the closed state, the limiting column 36 slides from the merging position to the end of the second positioning groove 222.

[0058] As Figure 3As shown, the limiting plate surface of the first connecting rod 20 is provided with a V-shaped groove 22, the V-shaped groove 22 includes a first positioning groove 221 and a second positioning groove 222, the first positioning groove 221 and the second positioning groove 222 are arranged like a “V” shape, both have a common convergence, and extend in different directions from the convergence. Understandably, the shape of the V-shaped groove 22 is the change trajectory of the relative position of the second connecting rod 30 to the first connecting rod 20 during the movement of the air deflector 50, and the position of the other end of the second connecting rod 30 is limited by using the change trajectory, so that the second connecting rod 30 cannot be affected by the user to affect the normal movement of the air deflector 50.

[0059] Optionally, the length of the first positioning groove 221 is not equal to the length of the second positioning groove 222.

[0060] The length of the first positioning groove 221 and the length of the second positioning groove 222 are related to the angle of the air deflector 50 opening upward and opening downward. When the angle of the air deflector 50 opening upward from the closed state is the same as the angle of opening downward, the length of the first positioning groove 221 is equal to the length of the second positioning groove 222. When the angle of the air deflector 50 opening upward from the closed state is different from the angle of opening downward, the length of the first positioning groove 221 is not equal to the length of the second positioning groove 222. Optionally, the length of the first positioning groove 221 can be greater than the length of the second positioning groove 222, and the length of the first positioning groove 221 can also be less than the length of the second positioning groove 222.

[0061] Optionally, the first connecting rod 20 and the second connecting rod 30 are rotatably connected with the air deflector 50. Optionally, one end of the first connecting rod 20 is provided with a first connecting hole 27, and one end of the second connecting rod 30 is provided with a second connecting hole 34.

[0062] Optionally, the first connecting rod 20 and the second connecting rod 30 are rotatably connected with the air deflector 50. Optionally, one end of the first connecting rod 20 is provided with a first connecting hole 27, and one end of the second connecting rod 30 is provided with a second connecting hole 34.

[0063] Optionally, the first connecting rod 20 and the second connecting rod 30 are provided with a connecting piece 60 between the mounting seat 52 of the air deflector 50, the connecting piece 60 is hinged with the first connecting hole 27 and the second connecting hole 34 respectively, and the connecting piece 60 is clamped with the mounting seat 52.

[0064] Optionally, the first connecting rod 20 is further provided with at least two sliding columns moving along the track portion, and the second connecting rod 30 is provided with at least two sliding columns moving along the track portion.

[0065] Optionally, the limiting plate surface of the first connecting rod 20 is provided with two sliding columns, and the two sliding columns are respectively located at the top end and the middle part of the first connecting rod 20. In order to distinguish the two sliding columns, the sliding column defined at the top end of the first connecting rod 20 is the first sliding column 25, and the sliding column at the middle part of the first connecting rod 20 is the second sliding column 26.

[0066] Optionally, the second plate surface opposite to the first plate surface of the second connecting rod 30 is provided with three sliding columns, and the three sliding columns are arranged in a triangular shape. As shown in Figure 5 in order to distinguish the above sliding columns, the three sliding columns of the second connecting rod 30 are defined as the third sliding column 31, the fourth sliding column 32 and the fifth sliding column 33. In this way, the limiting effect of the track plate 40 on the movement track of the second connecting rod 30 is improved.

[0067] Optionally, the second connecting rod 30 is provided with a through sliding channel 35 penetrating through the plate surface thereof, and the plate surface opposite to the second connecting rod 30 of the first connecting rod 20 is provided with a sliding column, and the sliding column passes through the through sliding channel 35 and moves along the track part.

[0068] It can be understood that the sliding column passing through the through sliding channel 35 is the second sliding column 26 of the first connecting rod 20. In the rotating process of the air deflector 50, the second sliding column 26 can slide in the through sliding channel 35, thereby generating relative displacement with the second connecting rod 30. That is, the through sliding channel 35 provides relative displacement for the first connecting rod 20 and the second connecting rod 30, so that the position of the upper end of the second connecting rod 30 cannot be limited. When the air deflector 50 is rotated to any angle, the user drives the second connecting rod 30 with hands, and the second connecting rod 30 will shake up and down, thereby affecting the normal movement of the air deflector 50. In this way, the limiting mechanism is provided in the embodiment of the present disclosure, the limiting column 36 is arranged at the upper part of the second connecting rod 30, and the V-shaped groove 22 is arranged on the limiting plate surface of the first connecting rod 20, so as to limit the upper end of the second connecting rod 30, thereby avoiding the shaking of the second connecting rod 30 affecting the normal rotation of the air deflector 50, and further improving the reliability of the connecting rod and the whole movement mechanism.

[0069] Optionally, the track part includes a first track and a second track, the first track is in a herringbone shape, and the first track is used for limiting the movement direction changing of the first connecting rod 20; the second track is in a straight line shape, and is arranged on the lower side of the first track along the direction in which the air deflector 50 extends, and the second track is used for limiting the straight line movement of the second connecting rod 30; wherein under the constraint of the first track and the second track, the first connecting rod 20 and the second connecting rod 30 first synchronously move in a straight line to drive the air deflector 50 to move to a first preset position, and then the first connecting rod 20 moves to change the direction and generates relative movement with the second connecting rod 30, thereby driving the air deflector 50 to rotate.

[0070] In the embodiment of the present disclosure, the first preset position is the position where the air deflector 50 is translated to extend out of the air conditioner and is about to start rotating, as shown inFigure 10 As shown, at this time, the air deflector 50 has a certain distance from the air outlet, and the air deflector 50 can be opened upward or downward at the first preset position. In the embodiment of the present disclosure, the rotating position of the air deflector 50 is not limited to the first preset position, and the first preset position is the initial position of the rotation of the air deflector 50. The rotation of the air deflector 50 can be understood as stretching out and rotating.

[0071] Optionally, the first track includes a first straight track 41, a first branch track 42 and a second branch track 43; the first branch track 42 is in communication with the first straight track 41, the second branch track 43 is in communication with the first straight track 41, and the extension directions of the first branch track 42 and the second branch track 43 are different.

[0072] In the embodiment of the present disclosure, the first sliding column 25 of the first connecting rod 20 moves in the first track, and the second sliding column 26 of the first connecting rod 20 moves in the second track. When the first sliding column 25 moves from the first straight track 41 to the first branch track 42 or the second branch track 43, the first connecting rod 20 will produce relative motion with the second connecting rod 30, and the first connecting rod 20 will change the direction of motion.

[0073] Optionally, the second track includes three straight tracks, i.e., a second straight track 44, a third straight track 45 and a fourth straight track 46. In the stretching out and rotating process of the air deflector 50, the second connecting rod 30 always moves linearly along the three straight tracks of the second track. Among them, the third sliding column 31 moves in the second straight track 44, the fourth sliding column 32 moves in the third straight track 45, and the fifth sliding column 33 moves in the fourth straight track 46. That is, the second connecting rod 30 moves linearly under the constraint of the three tracks.

[0074] It can be understood that the direction of the first straight track 41 and the direction of the second track are the same as the direction of the air deflector 50 stretching out from the closed state to the first preset position.

[0075] Optionally, the through slot 21 is in a linear type, and the first transmission shaft 121 slides in the through slot 21, thereby driving the movement of the first connecting rod 20. It can be understood that the direction of the through slot 21 can be perpendicular to the direction of the air deflector 50 stretching out from the closed state to the first preset position, or there can be a preset angle, and the direction of the through slot 21 is not limited in the present application.

[0076] Optionally, the diameter of the circle formed by the movement of the first transmission shaft 121 of the driving element 10 is less than or equal to the length of the through slot 21. In this way, the first transmission shaft 121 of the driving element 10 can be rotated by 90° in the first direction or the second direction from the initial position, and then continue to rotate, and the rotation angle of the first transmission shaft 121 is not limited by the length of the through slot 21.

[0077] Optionally, the driving element 10 is further provided with a second transmission shaft 122, and the first connecting rod 20 is further provided with a limiting groove 23, and the second transmission shaft 122 is slidably set in the limiting groove 23; the second transmission shaft 122 slides in the limiting groove 23 to provide driving force for the movement redirection of the first connecting rod 20.

[0078] Optionally, the first straight track 41 includes a straight section and a transition section that are connected to each other, and the transition section is connected to the first branch track 42 and the second branch track 43. Figure 7 As shown, the straight section and the transition section are indicated by dotted lines respectively. The upper part of the first straight track 41 is the straight section, and the part surrounded by the dotted line is the transition section. During the movement of the air deflector 50, when the first sliding column 25 of the first connecting rod 20 moves to the transition section, the transition section has no track constraint force on the first sliding column 25. In this way, the first connecting rod 20 may not move along the preset first branch track 42 or the second branch track 43 due to gravity. In this way, a limit groove 23 can be set on the first connecting rod 20, and the abutment force generated between the second transmission shaft 122 and the limit groove 23 provides the first sliding column 25 of the first connecting rod 20 with a driving force to select the first branch track 42 or the second branch track 43. The transition section is used to prevent the air deflector 50 from suddenly accelerating at the first preset position.

[0079] Optionally, the limiting groove 23 is located below the through groove 21 and is in communication with the through groove 21. In this way, when the first transmission shaft 121 drives the first connecting rod 20 to move, the second transmission shaft 122 can slide from the limiting groove 23 through the through groove 21 to the top of the through groove 21 without interfering with the movement of the first connecting rod 20.

[0080] Optionally, the limiting groove 23 is in the shape of a flared trumpet, and the inner edge of the limiting groove 23 includes a first flared section 231, a U-shaped section 233, and a second flared section 232 connected in sequence, and the first flared section 231 and the second flared section 232 are located on both sides of the U-shaped section 233. Optionally, a first limiting point is provided on the first flared section 231 to abut against the second transmission shaft 122, and a second limiting point is provided on the second flared section 232 to abut against the second transmission shaft 122. In the embodiment of the present disclosure, the first limiting point is as follows: Figure 2 The middle limit is represented by A and the second limit is represented by B.

[0081] The first transmission shaft 121 of the driving element 10 moves in the through slot 21 of the first connecting rod 20 to provide driving force for the movement of the first connecting rod 20, and the second transmission shaft 122 of the driving element moves in the limiting slot 23. It can be understood that, at the first limiting point A and the second limiting point B, the second transmission shaft 122 starts to abut against the inner edge of the limiting slot 23, so that the first connecting rod 20 can move along the preset track against gravity. Through the abutment force between the second transmission shaft 122 and the first limiting point A or the second limiting point B, driving force for the first sliding column 25 of the first connecting rod 20 to move along the first branch track 42 or the second branch track 43 is provided.

[0082] In the embodiments of the present disclosure, the shape of the first track of the herringbone shape on the track plate 40 is changed, and the shapes of the first branch track 42 and the second branch track 43 are convex outward, as shown in Figure 7 . Figure 7 Taking the first branch track 42 as an example, the center of the circle corresponding to the circular arc of the first branch track 42 is located on the right side of the first branch track 42, instead of on the left side as before. In order to adapt to the changes of the first branch track 42 and the second branch track 43, the shape of the transition section of the first straight section is also changed. In this way, the positions of the first limiting point and the second limiting point on the limiting slot 23 are changed. The position of the first limiting point changes from the connection between the U-shaped section 233 and the first flared section 231 to the position of point A, Figure 2 , and the position of the second limiting point changes from the connection between the U-shaped section 233 and the second flared section 232 to the position of point B, Figure 2 .

[0083] Designing the shapes of the first branch track 42 and the second branch track 43 to be convex outward can keep the speed of the air deflector 50 uniform during rotation, avoiding the situation that the rotation speed of the air deflector 50 becomes larger and larger, which affects the user experience.

[0084] Optionally, the first connecting rod 20 is further provided with a rolling part 28, which is used to move in the direction of movement of the first connecting rod 20 to reduce the friction during the movement of the first connecting rod 20.

[0085] In the disclosed embodiment, during the movement of the first connecting rod 20, due to the dimensional deviations that may exist between the first connecting rod 20 and its related components during the processing, there may be a certain degree of compression between the first connecting rod 20 and the related components. By providing the rolling portion 28 around the first connecting rod 20, the friction between the first connecting rod 20 and the related components during the movement can be reduced, thereby extending the service life of the first connecting rod 20 and the related components. It is understandable that the movement of the rolling portion 28 along the direction of movement of the first connecting rod 20 means that the rolling portion 28 can follow the first connecting rod 20 and move in the direction of movement of the first connecting rod 20, and does not refer to the movement direction of the rolling portion 28 itself. Optionally, the movement direction of the rolling portion 28 itself can be opposite to the movement direction of the first connecting rod 20.

[0086] Optionally, a rolling portion 28 is provided at the top of the first connecting rod 20. In this way, during the movement of the first connecting rod 20, the friction between the top and related components can be reduced, so that the first connecting rod 20 moves more smoothly. Optionally, the number of rolling portions 28 at the top of the first connecting rod 20 is two.

[0087] Optionally, the rolling portion 28 is also provided on one side of the through slot 21. The driving element 10 is slidably connected to the through slot 21, thereby providing a driving force for the movement of the first connecting rod 20, that is, the through slot 21 is the position of action of the driving force between the driving element 10 and the first connecting rod 20. Providing the rolling portion 28 on one side of the through slot 21, that is, providing the rolling portion 28 near the point where the above-mentioned driving force acts, is conducive to reducing the friction force near the force-bearing point of the first connecting rod 20. Especially when the first connecting rod 20 is tightly pressed, the pressure between the relevant components and the first connecting rod 20 can be reduced by providing the rolling portion 28 on one side of the through slot 21. Optionally, the rolling portion 28 can be provided on the upper side or the lower side of the through slot 21. Optionally, the number of rolling portions 28 provided on the lower side of the through slot 21 can be two.

[0088] Optionally, the rolling portion 28 includes a cylinder and a sleeve, one end of the cylinder is fixedly connected to the first connecting rod 20, and the other end is provided with a limiting end; the sleeve is sleeved on the outer surface of the cylinder and is clamped with the limiting end, and the sleeve is used to move along the movement direction of the first connecting rod 20; wherein, the outer diameter of the sleeve is greater than or equal to the thickness of the first connecting rod 20.

[0090] Optionally, the crank includes a rotating disk 11 and a rotating rod 12, the rotating disk 11 has a rotation center, and the rotating disk 11 is provided with a notch 111; the first end of the rotating rod 12 is fixedly connected to the notch 111, and the second end of the rotating rod 12 is a free end.

[0091] Optionally, the crank is drivingly connected with a motor, the motor provides driving force for the rotation of the crank, and the crank is slidingly connected with the first connecting rod 20 and drives the first connecting rod 20 to move.

[0092] Optionally, the first transmission shaft 121 is arranged at the free end of the rotating rod 12. In this way, the first transmission shaft 121 can slide on the first connecting rod 20 and drive the first connecting rod 20 to move. It can be understood that the rotating disc 11 has a driving surface in contact with the motor, the rotating rod 12 has a rotating surface in contact with the connecting rod, and the first transmission shaft 121 is arranged at the rotating surface of the rotating rod 12.

[0093] Optionally, the crank further comprises a second transmission shaft 122, the second transmission shaft 122 is used to change the direction of the movement of the first connecting rod 20. The second transmission shaft 122 is arranged at the rotating surface of the rotating rod 12 and is located between the first end of the rotating rod 12 and the first transmission shaft 121. The second transmission shaft 122 can provide driving force for the first connecting rod 20 to select the track.

[0094] The movement mechanism for the air deflector 50 provided by the embodiments of the present disclosure drives the air deflector 50 to move in the following way:

[0095] The initial state of the movement assembly of the air deflector 50 in the closed state is shown in Figure 1 When the driving element 10 rotates in the first direction or the second direction from the initial position shown in Figure 1 , the first transmission shaft 121 slides in the through slot 21 of the first connecting rod 20 to drive the first connecting rod 20 and the second connecting rod 30 to move. Among them, the first connecting rod 20 moves linearly along the straight line segment of the first linear track 41, the second connecting rod 30 moves linearly along the second track, and the air deflector 50 moves linearly to the first preset position. The first preset position can be understood as the position of the air deflector 50 corresponding to the movement of the first sliding column 25 of the first connecting rod 20 to the end of the straight line segment. In the embodiments of the present disclosure, the first direction is the clockwise direction based on Figure 1 , and the second direction is the counterclockwise direction based on Figure 1 .

[0096] When the driving element 10 rotates in the first direction, when the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the driving element 10 moves to the first limit point A, and because of the abutting force between the second transmission shaft 122 and the first limit point A, a driving force for selecting the track of the first sliding column 25 of the first connecting rod 20 is provided, so that the first sliding column 25 of the first connecting rod 20 enters the first branch track 42 from the first straight track 41, the second sliding column 26 of the first connecting rod 20 continues to move in the second straight track 44 through the through sliding channel 35 of the second connecting rod 30, and the first connecting rod 20 is changed in direction. At the same time, the second connecting rod 30 continues to move linearly along the second track, so that the air deflector 50 is opened upward under the joint driving of the first connecting rod 20 and the second connecting rod 30, as shown in Figure 11 .

[0097] When the driving element 10 rotates in the second direction, when the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the driving element 10 moves to the second limit point B, and because of the abutting force between the second transmission shaft 122 and the second limit point B, a driving force for selecting the track of the first sliding column 25 of the first connecting rod 20 is provided, so that the first sliding column 25 of the first connecting rod 20 enters the second branch track 43 from the first straight track 41, the second sliding column 26 of the first connecting rod 20 continues to move in the second straight track 44 through the through sliding channel 35 of the second connecting rod 30, and the first connecting rod 20 is changed in direction.
