[0044] 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.

[0045] The embodiments of the present disclosure provide an air conditioner, as shown in the drawings. Figure 1

[0046] 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 is first extended out of the air conditioner and then rotated 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 embodiments of the present disclosure can be a single cold machine, and the movement mechanism can only open the air deflector 50 upward to supply air. Alternatively, the air conditioner provided by the embodiments of the present disclosure can also be a hot air machine, and the movement mechanism can only open the air deflector 50 downward to supply air.

[0047] In some embodiments, the air conditioner comprises the movement mechanism for the air deflector 50 described above. Alternatively, the single cold machine comprises the movement mechanism for the air deflector 50 described above.

[0048] Alternatively, the air deflector 50 is provided with a movement mechanism on each side, and the movement mechanisms on both sides drive the air deflector 50 to move simultaneously. The structure and movement process of the movement mechanism will be described in detail below taking the movement mechanism on the right side of the air deflector 50 as an example.​

[0049] The embodiment of the present disclosure further provides a movement mechanism for the air deflector 50, as shown in Figures 2 to 13

[0050] 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 rotatably arranged on the air conditioner; one end of the first connecting rod 20 is rotatably connected with the air deflector 50, and the other end is slidably connected with the driving element 10, the first connecting rod 20 comprises a first limiting part; one end of the second connecting rod 30 is rotatably connected with the air deflector 50, and the second connecting rod 30 comprises a second limiting part; the track plate 40 is fixedly arranged on the air conditioner, the track plate 40 comprises a first track and a second track, the first limiting part is slidably arranged in the first track and the second track, and the second limiting part is slidably arranged in the second track; wherein the first track comprises an arc-shaped track 42 extending in one direction, so that the first connecting rod 20 cooperates with the second connecting rod 30 under the driving of the driving element 10, and drives the air deflector 50 to extend out of the air conditioner and then to open upward or downward.

[0051] The movement mechanism provided by the embodiment of the present disclosure comprises a driving element 10, a first connecting rod 20, a second connecting rod 30 and a track plate 40, the track plate 40 is provided with a first track and a second track, the first limiting part of the first connecting rod 20 is matched with the first track and the second track at the same time, and the second limiting part of the second connecting rod 30 is matched with the second track. In this way, the movement trajectory of the first connecting rod 20 and the second connecting rod 30 can be limited by the track plate 40, so that the first connecting rod 20 can drive the air deflector 50 to rotate after extending out of the air conditioner under the driving of the driving element 10. The first track comprises an arc-shaped track 42 extending in one direction, so that the air deflector 50 can extend out of the air conditioner and then open upward or downward, meeting the air supply demand of a single cold machine or a hot air machine.

[0052] The movement mechanism provided by the embodiment of the present disclosure can drive the air deflector 50 to extend and rotate by arranging one driving element 10, simplifying the structure of the movement mechanism, and increasing the air supply distance and range of the air conditioner, so that the air conditioner can reach the preset temperature faster. At the same time, the air volume per unit area is reduced, the air blown by the air conditioner is softer, and the comfort of the user is improved.

[0053] Optionally, the arc-shaped track 42 is outward convex, so that the air deflector 50 rotates at a constant speed in the process of opening upward or downward.

[0054] Wherein, the outward convex refers to that the center of the circle where the arc-shaped track 42 is located is located on the lower side of the arc-shaped track 42, as shown in Figure 3 ​As shown, the first limiting portion of the first connecting rod 20 moves in the arc-shaped track 42, so that the air deflector 50 can rotate at a uniform speed after extending out of the air conditioner, avoiding the situation that the air deflector 50 quickly rotates to open upward or downward after extending out of the air conditioner.

[0055] The embodiments of the present disclosure also provide another track plate 40, as shown in Figure 4 Figure 3 and Figure 4 The bending directions of the arc-shaped tracks 42 in the two track plates 40 shown are different. Figure 4 As shown, the arc-shaped track 42 is concave, that is, the center of the circle where the arc-shaped track 42 is located is located on the upper side of the arc-shaped track 42.

[0056] The movement trajectories of the air deflector 50 driven by the other components of the movement mechanism are different for the above two arc-shaped tracks 42 with different shapes, and the bending direction of the arc-shaped track 42 can affect the speed of the air deflector 50 during rotation. Figure 3 As shown, the arc-shaped track 42 of the track plate 40 is convex, so that the air deflector 50 can rotate at a uniform speed after extending out of the air conditioner. Figure 4 As shown, the arc-shaped track 42 of the track plate 40 is concave, so that the rotation speed of the air deflector 50 after extending out of the air conditioner will become faster and faster, and the air deflector 50 will quickly open upward or downward, directly affecting the sensory experience of the user.

[0057] In order to more intuitively reflect the rotation speed of the air deflector 50 after extending out of the air conditioner, the embodiments of the present disclosure provide a comparison diagram of the rotation speed of the air deflector 50 driven by the above two track plates 40 Figure 5 . Among them, the rotation speed of the air deflector 50 can be understood as the angular speed of rotation.

[0058] As shown in Figure 5 , the solid line in the figure is the change trend of the rotation speed of the air deflector 50 with time using the track plate 40 shown in Figure 3 . In the time period of 0-2 seconds, the rotation speed of the air deflector 50 is 0, indicating that the air deflector 50 does not rotate during the extension process; in the time period of 2-4 seconds, the rotation speed of the air deflector 50 begins to gradually increase, indicating that the air deflector 50 gradually begins to rotate after extending out of the air conditioner; in the time period of 4-10 seconds, the rotation speed of the air deflector 50 remains unchanged, indicating that the air deflector 50 can basically maintain a uniform speed during rotation.

[0059] As shown in Figure 5 , the dotted line in the figure is the change trend of the rotation speed of the air deflector 50 with time using the track plate 40 shown in Figure 4 ​The variation trend of the rotation speed of the air deflector 50 of the track slab 40 shown over time. In the time period from 0 to 2 seconds, the rotation speed of the air deflector 50 is 0, indicating that the air deflector 50 does not rotate during the extension process; in the time period from 2 to 4 seconds, the rotation speed of the air deflector 50 begins to gradually increase, indicating that the air deflector 50 starts to rotate after extending out of the air conditioner; in the time period from 4 to 10 seconds, the rotation speed of the air deflector 50 gradually increases, indicating that the speed of the air deflector 50 is getting faster and faster during the rotation process.

[0060] Through the above Figure 5 Comparison of the simulation experiment data of measuring the rotation speed of the air deflector 50 by using two track slabs 40 shown above. From the rotation speed curve of the air deflector 50 in the time period from 4 to 10 seconds, it can be seen that the track slab 40 with the convex arc-shaped track 42 provided by the embodiment of the present disclosure can cooperate with other components of the moving mechanism to drive the air deflector 50 to rotate uniformly after extending out of the air conditioner, avoiding the phenomenon that the speed of the air deflector 50 becomes faster and faster during the rotation process and improving the user's sensory experience.

[0061] Optionally, the radian of the arc-shaped track 42 is greater than or equal to 10° and less than or equal to 25°. In this way, the air deflector 50 can rotate uniformly to the maximum opening angle after extending out of the air conditioner.

[0062] Optionally, the first track further includes a first straight track 41. The first straight track 41 is arranged above the arc-shaped track 42 and is connected to the starting end of the arc-shaped track 42. The arc-shaped track 42 is arranged on one side of the first straight track 41. Both the first straight track 41 and the second track are linear and are arranged along the direction in which the air deflector 50 extends; wherein, the first connecting rod 20 first moves along the first straight track 41, and the second connecting rod 30 moves along the second track, and then the synchronous linear motion drives the air deflector 50 to extend to the first preset position first. After that, the first connecting rod 20 and the second connecting rod 30 move relatively, and then drive the air deflector 50 to open upward uniformly.

[0063] The track slab 40 provided by the embodiment of the present disclosure as Figure 3 shown can be used in a single-cooling machine. The shape of the arc-shaped track 42 is similar to the right stroke of the Chinese character "ren". The first straight track 41 is arranged above the arc-shaped track 42 and is connected to the starting end of the arc-shaped track 42. Among them, the starting end of the arc-shaped track 42 is Figure 3 the upper end of the arc-shaped track 42 shown in

[0064] Optionally, the second straight track 44 includes multiple straight tracks, and the multiple straight tracks are arranged on one side of the first track. As Figure 3 shown, the multiple straight tracks are arranged on the left side of the first track.

[0065] In the embodiments of the present disclosure, the first preset position is a position at which the air deflector 50 is about to start rotating after being translated out of the air conditioner, as shown in Figure 12 At this time, the air deflector 50 has a certain distance from the air outlet, and the air deflector 50 can be opened upward at the first preset position. In the embodiments of the present disclosure, the rotating position of the air deflector 50 is not limited to the first preset position. The first preset position is the initial position of the rotation of the air deflector 50, and the rotation of the air deflector 50 can be understood as being translated out and rotated at the same time.

[0066] Optionally, the first limiting part includes at least two sliding columns. Optionally, the two sliding columns are respectively slidingly arranged in the first track and the second track.

[0067] As shown in Figure 7 , the first limiting part includes a first sliding column 25 and a second sliding column 26. The first sliding column 25 is arranged at the top end of the first connecting rod 20, and the second sliding column 26 is arranged at the middle part of the first connecting rod 20. The first sliding column 25 is slidingly arranged in the first track, and the second sliding column 26 is slidingly arranged in one of the straight tracks of the second track. When the first sliding column 25 moves from the first straight track 41 to the arc-shaped track 42, the second connecting rod 30 always moves linearly along the second track, and the first connecting rod 20 will produce relative motion with the second connecting rod 30, the first connecting rod 20 changes the direction of motion, and then cooperates with the second connecting rod 30 to drive the air deflector 50 to rotate upward at a constant speed.

[0068] Optionally, the second limiting part includes at least two sliding columns, and the sliding columns are slidingly arranged in the second track.

[0069] As shown in Figure 8 , the second limiting part of the second connecting rod 30 includes a third sliding column 31, a fourth sliding column 32 and a fifth sliding column 33, and the three sliding columns are arranged in a triangular shape. In this way, the limiting effect of the track plate 40 on the movement track of the second connecting rod 30 is improved.

[0070] Optionally, the first straight track 41 includes a straight section and a transition section. The transition section is arranged at the communication position of the straight section and the arc-shaped track 42, and the transition section is arranged in an arc shape on both sides along the direction in which the arc-shaped track 42 extends. The transition section is used to avoid the air deflector 50 from suddenly accelerating at the first preset position.

[0071] As shown in Figure 3 , the transition section is arranged in an arc shape on both sides along the direction in which the arc-shaped track 42 extends. Figure 3The straight line segment and the transition segment are respectively shown by a dashed line. The upper part of the first linear track 41 is a straight line segment, and the part surrounded by the dashed line in the lower part of the first linear track 41 is a transition segment. If the first linear track 41 does not have the transition segment, the rotation speed of the air deflector 50 will suddenly increase at the first preset position. From a visual point of view, the air deflector 50 suddenly changes from the state of stretching out in translation to the state of rapidly rotating, which directly affects the user experience. After the first linear track 41 is provided with the transition segment, the air deflector 50 can gradually start to rotate from the state of stretching out in translation, and the sudden acceleration does not occur, thereby improving the degree of precise control over the movement process of the air deflector 50.

[0072] Optionally, the time ratio of the movement of the first connecting rod 20 along the first linear track 41 and the arc-shaped track 42 is greater than or equal to 0.5 and less than or equal to 0.7.

[0073] By limiting the time ratio of the movement of the first sliding column 25 in the first linear track 41 and the arc-shaped track 42, the air deflector 50 can rotate at a moderate speed in the process of opening upward. At the same time, the air deflector 50 can also stretch out an appropriate distance before rotating, avoiding the air deflector 50 from colliding with the shell of the air conditioner. For example, the time ratio of the movement of the first sliding column 25 in the first linear track 41 and the arc-shaped track 42 can be 2:3, or 3:5, etc.

[0074] Optionally, the second track includes a second linear track 44, a third linear track 45 and a fourth linear track 46. The second linear track 44 is arranged along the direction in which the air deflector 50 stretches out and is located on the same straight line as the first linear track 41. The third linear track 45 is arranged on one side of the second linear track 44. The fourth linear track 46 is arranged on the other side of the second linear track 44. The second linear track 44, the third linear track 45 and the fourth linear track 46 are all located on one side of the first track.

[0075] Optionally, the second linear track 44, the third linear track 45 and the fourth linear track 46 are track grooves penetrating the track plate 40. In this way, the second sliding column 26 and the three sliding columns of the second limiting part can stably slide in the track grooves, thereby improving the stability of the movement of the connecting rod in the track. The third sliding column 31 moves in the second linear track 44, the fourth sliding column 32 moves in the third linear track 45, and the fifth sliding column 33 moves in the fourth linear track 46.

[0076] Optionally, the second connecting rod 30 is further provided with a penetrating sliding channel 35 penetrating the plate surface of the second connecting rod 30. The penetrating sliding channel 35 provided on the second connecting rod 30 enables the second sliding column 26 of the first connecting rod 20 to move along the second track through the penetrating sliding channel 35.

[0077] Optionally, the first connecting rod 20 and the second connecting rod 30 are both rotationally 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.

[0078] Optionally, a connecting piece 60 is arranged between the first connecting rod 20, the second connecting rod 30 and the mounting seat 52 of the air deflector 50. The connecting piece 60 is hingedly connected 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.

[0079] Optionally, the connecting piece 60 includes a connecting body 64, a first mounting portion 61, a second mounting portion 62 and a clamping portion 63, as shown in Figure 10 The first connecting hole 27 is hingedly connected with the first mounting portion 61, and the second connecting hole 34 is clamped with the second mounting portion 62. By arranging the connecting piece 60 between the mounting seat 52 of the air deflector 50 and the first connecting rod 20 and the second connecting rod 30, the disassembly and assembly of the air deflector 50 can be facilitated, and the assembly efficiency of the air deflector 50 is improved.

[0080] The driving element 10 includes a transmission shaft 121 arranged at the free end of the driving element 10. The first connecting rod 20 is provided with a through slot 21, and the transmission shaft 121 is slidingly arranged in the through slot 21 to provide a driving force for the movement of the first connecting rod 20.

[0081] The driving element 10 is provided with only one transmission shaft 121 which is slidingly arranged in the through slot 21 of the first connecting rod 20 to provide a driving force for the extension of the air deflector 50 driven by the first connecting rod 20.

[0082] Optionally, the through slot 21 is linear, and the diameter of the circle formed by the movement of the 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 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 continue to rotate, and the rotation angle of the driving element 10 is not limited by the length of the through slot 21.

[0083] In the embodiment of the present disclosure, the driving element 10 can be a crank, as shown in Figure 9 .

[0084] Optionally, the crank includes a rotating disc 11 and a rotating rod 12. The rotating disc 11 has a rotation center, the first end of the rotating rod 12 is integrally connected with the rotating disc 11, and the second end of the rotating rod 12 is a free end.

[0085] Optionally, the crank is drivenly connected with a motor. The driving shaft of the motor is arranged in a groove at the rotation center of the crank. The motor provides a driving force for the rotation of the crank, so that the crank can be slidingly connected with the first connecting rod 20 and drive the first connecting rod 20 to move.

[0086] Optionally, the transmission shaft 121 is arranged at the free end of the rotating rod 12. In this way, the transmission shaft 121 can slide on the first connecting rod 20 to 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 disc 11 and the rotating rod 12 have rotating surfaces in contact with the first connecting rod 20, and the transmission shaft 121 is arranged on the rotating surface of the rotating rod 12.

[0088] As shown in Figure 6 , the hollow area 22 is arranged above the through groove 21, and the arrangement of the hollow area 22 makes the first connecting rod 20 lightweight, so that the torque of the motor can be reduced during the movement of the first connecting rod 20 driven by the motor-driven crank. At the same time, limiting the size of the hollow area 22 can also make the first connecting rod 20 have the reliability of movement.

[0089] The movement mode of the movement mechanism for the air deflector 50 provided by the embodiments of the present disclosure is as follows:

[0090] The initial state of the movement mechanism of the air deflector 50 in the closed state is as shown in Figure 2 . When the driving element 10 rotates in the first direction from the initial position as shown in Figure 2 , the transmission shaft 121 slides in the through groove 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 along the straight line segment of the first linear track 41, the second connecting rod 30 moves linearly along the second track, and then drives the air deflector 50 to move 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, as shown in Figure 12 . In the embodiments of the present disclosure, the first direction is based on the clockwise direction as shown in Figure 2 .

[0091] When the air deflector 50 reaches the first preset position, the transmission shaft 121 continues to slide in the through groove 21, the first sliding column 25 of the first connecting rod 20 enters the transition segment of the first linear track 41 and moves along the arc-shaped track 42, and the second sliding column 26 of the first connecting rod 20 continues to move in the second track. In this way, the first connecting rod 20 starts to move to turn, the first connecting rod 20 and the second connecting rod 30 produce relative movement, and then jointly drive the air deflector 50 to open upward to meet the air supply demand of the single cold machine, as shown in Figure 13 .
