It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0050] The indoor unit of the current air conditioner has a relatively simple air sweeping mode, which can basically only sweep up and down, with a small air sweeping range, a single mode, and a poor user experience.

[0051] For this, see Figure 1 and 2An embodiment of the present application provides an air guide mechanism 10, comprising an air guide blade 20, a drive unit 30 and a transmission mechanism 40; the drive unit 30 is used to output movement; the transmission mechanism 40 is connected to the air guide blade 20 and the drive unit 30, so as to convert the movement output by the drive unit 30 into movement of the air guide blade 20 along a first direction and swinging in the first direction.

[0052] It should be noted that the specific implementation form of the wind guide blade 20 is not limited, and it can be only one blade or multiple blades. When multiple blades are included, the multiple blades can swing when moving along the first direction, or some can swing while the other part does not swing, one of every two adjacent blades can swing, or the blades can swing randomly, or only one blade can swing, etc., which are not limited here. The specific implementation form of the drive unit 30 is not limited, and it can be a drive motor, a drive cylinder, etc., which are not limited here. The specific implementation form of the transmission mechanism 40 is not limited, and it can be a connecting rod, a gear, a gear, etc. A combination of racks, for example, the driving cylinder is transmission-connected to the air guide blade 20 through a connecting rod, the air guide blade 20 is rotatably mounted on the connecting rod, a gear is provided on the air guide blade 20, and the rack is fixedly mounted on the housing 50 of the air-conditioning indoor unit 100, the driving cylinder drives the connecting rod to move in the first direction, the air guide blade 20 moves along the first direction, and then the gear rotates under the action of the rack, driving the air guide blade 20 to rotate, so that the air guide blade 20 swings in the first direction. Of course, the gear and the rack can also be replaced by a combination of a chain and a sprocket, or a combination of a transmission belt and a rotating wheel, etc., which are not limited here.

[0053] The specific implementation form of the first direction is not limited. Taking the application of the air guide mechanism 10 on an air-conditioning cabinet as an example, at this time, the first direction can be the up and down direction. When the air guide mechanism 10 is applied to an air-conditioning wall-mounted unit, the first direction can be the up and down direction or the left and right direction, etc., which is not limited here.

[0054] It should be emphasized that the movement of the air guide blade 20 along the first direction means that the air guide blade 20 moves as a whole in the first direction.

[0055] The embodiment of the present application sets up a transmission mechanism 40 to transmit and connect the air guide blade 20 and the driving unit 30, and the transmission mechanism 40 converts the movement output by the driving unit 30 into the movement of the air guide blade 20 along the first direction and the swinging in the first direction. Therefore, under the drive of the driving unit 30, the air guide blade 20 can swing in the first direction while moving along the first direction, thereby enriching the air supply mode of the air conditioner and giving the experiencer a new experience.

[0056] In further embodiments, please refer to Figure 8 The air guide blade 20 has a free end 212 and a mounting end, and the transmission mechanism 40 includes a first transmission component 11 and a second transmission component 15. The first transmission component 11 is transmission-connected to the driving unit 30 and the air guide blade 20, and the first transmission component 11 has a movable end that can move along a first direction, and the mounting end of the air guide blade 20 can be rotatably mounted on the movable end; the second transmission component 15 is connected to the air guide blade 20, and is used for converting the movement of the air guide blade 20 along the first direction into the swinging of the free end 212 of the air guide blade 20 along the first direction when the air guide blade 20 moves along the first direction.

[0057] In the technical solution of this embodiment, the driving unit 30 outputs motion, and after conversion by the first transmission component 11, the motion output by the driving unit 30 is converted into movement of its moving end along the first direction. Correspondingly, at this time, the mounting end of the air guide blade 20 is rotatably mounted on the moving end. Therefore, when the moving end moves along the first direction, the mounting end of the air guide blade 20 will also move with the moving end, driving the air guide blade 20 to move as a whole in the first direction. At this time, the second transmission component 15 converts the movement of the air guide blade 20 along the first direction into the swinging of the free end 212 of the air guide blade 20 along the first direction, so that when the air guide blade 20 moves as a whole along the first direction, its free end 212 can also swing in the first direction.

[0058] It should be noted that the specific implementation forms of the first transmission assembly 11 and the second transmission assembly 15 are not limited, and may be in the form of a multi-link, or in the form of a gear, a rack, etc., which are not limited here.

[0059] For further information, please also refer to Figures 2 to 6 and Figure 8The second transmission assembly 15 includes a driven rack 16 and a driven gear 17, the driven gear 17 is fixedly mounted on the mounting end of the air guide blade 20, the driven rack 16 is arranged on one side of the driven gear 17 in the second direction and is meshed with the driven gear 17, and the driven rack 16 is fixedly mounted on the housing 50 of the air conditioner indoor unit 100.

[0060] In the technical solution of this embodiment, when the first transmission component 11 drives the air guide blade 20 to move along the first direction, the air guide blade 20 drives the driven gear 17 to move on the driven rack 16. Due to the action of the rack teeth on the driven rack 16, the driven gear 17 is rotated. Since the driven gear 17 is fixedly installed on the mounting end of the air guide blade 20, after the driven gear 17 rotates, the mounting end of the air guide blade 20 will rotate with the driven gear 17, thereby allowing the free end 212 of the air guide blade 20 to swing along the first direction.

[0061] Please note that Figure 3 , Figure 4 and Figure 8 , the driven rack 16 can be provided with only one, and the corresponding driven rack 16 is arranged on any side of the driven gear 17 in the second direction. Taking the first direction as the up and down direction and the second direction as the left and right direction as an example, in one embodiment, the driven rack 16 is arranged on the left side of the driven gear 17. Correspondingly, at this time, the driving unit 30 drives the first transmission assembly 11 to drive the air guide blade 20 to move upward, and the driven gear 17 moves upward relative to the driven rack 16. Correspondingly, at this time, the free end 212 of the air guide blade 20 can also swing upward, and correspondingly, in the process of moving downward, the free end 212 of the air guide blade 20 can also swing downward. Therefore, under the drive of the driving unit 30, the air guide blade 20 can swing upward in the process of moving upward, and can swing downward in the process of moving downward. Compared with the single up and down movement form, the air supply range is wider and the user experience is better.

[0062] Of course, the driven rack 16 can also be arranged on the right side of the driven gear 17. Correspondingly, at this time, the driving unit 30 drives the first transmission assembly 11 to drive the air guide blade 20 to move upward, and the driven gear 17 moves upward relative to the driven rack 16. Under the action of the driven rack 16, the driven gear 17 rotates, and the free end 212 of the air guide blade 20 can swing downward. Correspondingly, in the process of moving downward, the free end 212 of the air guide blade 20 can swing upward. Compared with the single up and down movement form, the air supply is more concentrated.

[0063] Of course, see Figure 5 , Figure 6 and Figure 8 The driven rack 16 can also be provided with two, the two driven racks 16 are arranged on both sides of the driven gear 17, and the tooth portions 141 of the two driven racks 16 are staggered. In this way, since the driven rack 16 is provided with two, the stability of the driven gear 17 is better, and the tooth portions 141 of the two driven racks 16 are staggered, which can effectively prevent the driven gear 17 from getting stuck and unable to rotate.

[0064] Furthermore, it should be noted that the second transmission assembly 15 is composed of a driven gear 17 and a driven rack 16 , which has lower cost, simpler structure and better stability during transmission compared to other forms.

[0065] In addition, the specific implementation form of the wind guide blade 20 is not limited, and may include only the active blade 21, or may include the active blade 21 and the driven blade 22. No limitation is made here. It should be noted that the active blade 21 refers to the blade directly driven by the first transmission assembly 11, and the driven blade 22 refers to the blade driven by the active blade 21 after the active blade 21 moves.

[0066] In one embodiment, see Figure 1 , 3 , 5 and 8, the wind guide blade 20 includes at least an active blade 21, the mounting end 211 of the active blade constitutes the mounting end of the wind guide blade 20, the mounting end 211 of the active blade is fixedly provided with a rotating shaft 213, and the driven gear 17 is arranged at one end of the rotating shaft 213 away from the mounting end 211 of the active blade; the rotating shaft 213 of the active blade is rotatably mounted on the moving end of the first transmission assembly 11.

[0067] In the technical solution of this embodiment, the rotating shaft 213 of the active blade is rotatably installed on the moving end of the first transmission component 11, so that when the moving end of the first transmission component 11 moves along the first direction, it can pull the rotating shaft 213 of the active blade to move along the first direction. Correspondingly, at this time, the rotating shaft 213 of the active blade drives the active blade 21 and the driven gear 17 to move along the first direction, and the driven gear 17 rotates under the action of the driven rack 16, driving the rotating shaft 213 of the active blade and the active blade 21 to rotate in the opposite direction. In addition, by setting the rotating shaft 213, the interference of the first transmission component 11 on the rotation of the driven gear 17 can be avoided, thereby improving the stability of the rotation of the active blade 21.

[0068] For further information, see Figures 1 to 4 In one embodiment, the first transmission assembly 11 includes a connecting rod assembly 12, including at least a first connecting rod 121 and a second connecting rod 122, the first connecting rod 121 and the second connecting rod 122 each having a first end and a second end arranged opposite to each other along their length direction, the second ends of the first connecting rod 121 and the second connecting rod 122 are hinged to each other through the rotating shaft 213 of the active blade, and the first end of the first connecting rod 121 is used to be rotatably installed on the housing 50 of the air-conditioning indoor unit 100; wherein the driving unit 30 is used to drive the first end of the second connecting rod 122 to move in the second direction toward or away from the first end of the first connecting rod 121, so as to drive the rotating shaft 213 of the active blade to move in the first direction.

[0069] It should be noted that, in the present embodiment, the second ends of the first link 121 and the second link 122 constitute the movable end. Taking the first direction as the up-down direction as an example, the second ends of the first link 121 and the second link 122 may be located above the first ends of the first link 121 and the second link 122. Correspondingly, at this time, the driving unit 30 drives the first end of the second link 122 to move in the second direction close to the first end of the first link 121, the first link 121 and the second link 122 are both folded, the second ends of the first link 121 and the second link 122 move upward, driving the active blade 21 to move upward together, the driving unit 30 drives the first end of the second link 122 to move in the second direction away from the first end of the first link 121, the first link 121 and the second link 122 are both unfolded, the second ends of the first link 121 and the second link 122 move downward, driving the active blade 21 to move downward together.

[0070] Of course, the second ends of the first link 121 and the second link 122 may be located below the first ends of the first link 121 and the second link 122. Correspondingly, at this time, the driving unit 30 drives the first end of the second link 122 to move in the second direction close to the first end of the first link 121, the first link 121 and the second link 122 are both folded, the second ends of the first link 121 and the second link 122 move downward, driving the active blade 21 to move downward together, and the driving unit 30 drives the first end of the second link 122 to move in the second direction away from the first end of the first link 121, the first link 121 and the second link 122 are both unfolded, the second ends of the first link 121 and the second link 122 move upward, driving the active blade 21 to move upward together, and no limitation is made here.

[0071] In the technical solution of this embodiment, by setting the first connecting rod 121 and the second connecting rod 122, the lengths of the first connecting rod 121 and the second connecting rod 122 can be controlled, and the stroke size and speed of the movement of the active blade in the first direction are correspondingly controlled. Compared with the solution of using a single connecting rod for direct transmission, for example, the solution of using a cylinder and a connecting rod, the movement stability is higher and the movement stroke size is better controlled.

[0072] Of course, in other embodiments, the wind guide blade 20 may also include a plurality of active blades 21. Correspondingly, at this time, the first transmission assembly 11 further includes a linkage rod, the second ends of the first link 121 and the second link 122 and one end of the linkage rod are hinged to each other, and the rotating shafts 213 of the plurality of active blades are rotatably mounted on the linkage rod. Correspondingly, at this time, when the second ends of the first link 121 and the second link 122 move in the first direction, the linkage rod is pulled to move in the first direction, and the linkage rod simultaneously drives the plurality of active blades 21 to move in the first direction. Correspondingly, in this embodiment, the linkage rod constitutes the moving end.

[0073] In a further embodiment, the connecting rod assembly 12 also includes a third connecting rod 123 and a fourth connecting rod 124, and the third connecting rod 123 and the fourth connecting rod 124 each have a first end and a second end arranged opposite to each other along their length direction, and the second ends of the third connecting rod 123 and the fourth connecting rod 124 are hinged to each other, and the first ends of the third connecting rod 123 and the fourth connecting rod 124 are hinged to the first ends of the first connecting rod 121 and the second connecting rod 122, respectively.

[0074] In this embodiment, by setting the third connecting rod 123 and the fourth connecting rod 124, they can be connected end to end with the first connecting rod 121 and the second connecting rod 122 to form a four-bar linkage. Since the four-bar linkage has stability, it can improve the stability of the active blade 21 moving in the first direction, and when the active blade 21 moves eccentrically in the first direction, it can also automatically adjust the eccentricity.

[0075] Furthermore, the first connecting rod 121, the second connecting rod 122, the third connecting rod 123 and the fourth connecting rod 124 have the same length. With this arrangement, on the one hand, the effect of adjusting the eccentricity is better, and on the other hand, the four can be used universally, thereby reducing the cost of production.

[0076] At the same time, the second end of the third connecting rod 123 and the second end of the first connecting rod 121 are arranged opposite to each other in the first direction, and the second end of the third connecting rod 123 is located on the side of the second end of the first connecting rod 121 away from the air guide plate.

[0077] Taking the first direction as the up and down direction as an example, the second end of the third connecting rod 123 is located on the side of the second end of the first connecting rod 121 away from the wind guide plate, that is, the second end of the third connecting rod 123 is located above the first connecting rod 121. At this time, since the third connecting rod 123 and the active blade 21 are spaced apart in the up and down directions, the third connecting rod 123 can be effectively prevented from interfering with the movement of the active blade 21 in the up and down directions.

[0078] At the same time, the specific implementation form of the driving unit 30 is not limited. It can be directly driven by a driving cylinder to drive the first end of the second connecting rod 122 to move, or it can be driven by a driving motor. In one embodiment, the driving unit 30 includes a driving motor, and the first transmission assembly 11 also includes a driving gear 13 and an driving rack 14, which are fixedly mounted on the rotating shaft of the driving motor; the driving rack 14 is engaged with the driving gear 13, and the driving rack 14 is rotatably connected to the first end of the second connecting rod 122 and extends along the second direction, so as to drive the first end of the second connecting rod 122 to move in the second direction under the rotation of the driving gear 13.

[0079] In the technical solution of this embodiment, under the rotation of the rotating shaft of the driving motor, the active gear 13 rotates synchronously with the rotating shaft of the driving motor. Under the rotation of the active gear 13, the active rack 14 moves along the second direction. At the same time, since the first end of the second connecting rod 122 is also rotatably connected to the active rack 14, the first end of the second connecting rod 122 will also move along the second direction with the active rack 14. The first connecting rod 121 and the second connecting rod 122 rotate with each other to be folded or unfolded, so that the second ends of the first connecting rod 121 and the second connecting rod 122 move in the first direction. Compared with the direct driving method using the driving cylinder, such a setting can slow down the movement rate due to the transmission effect of the active gear 13 and the active rack 14, improve the stability of the movement of the active blade 21, and better control the movement stroke.

[0080] See also Figure 1 , 2 9. In a further embodiment, the active rack 14 includes two tooth portions 141 arranged at intervals along the first direction, and a connecting portion 142 connecting the two tooth portions 141; the two tooth portions 141 are clamped on both sides of the active gear 13 in the first direction; the connecting portion 142 is rotatably connected to the first end of the second connecting rod 122.

[0081] In the technical solution of this embodiment, the active rack 14 includes two tooth portions 141. Under the rotation of the active gear 13, the two tooth portions 141 can be driven to move in the second direction at the same time, and the driving stability is higher. In addition, the two tooth portions 141 are clamped on both sides of the active gear 13 in the first direction, which can prevent the active rack 14 from falling off the active gear 13, thereby further improving the stability of the transmission.

[0082] The connection portion 142 is rotatably connected to the first end of the second connecting rod 122 , so that the second connecting rod 122 can avoid interfering with the movement of the tooth portion 141 and the driving gear 13 .

[0083] In the meantime, please see Figure 1 and Figure 3 The wind guide blade 20 also includes a plurality of driven blades 22 and a connecting rod 23. The rotating shaft 213 of the active blade is rotatably mounted on the connecting rod 23. The driven blade 22 is rotatably mounted on the connecting rod 23 via the rotating shaft, so that when the active blade 21 moves along the first direction, the connecting rod 23 and the plurality of driven blades 22 are driven to move in the first direction; and the plurality of driven blades 22 are spaced apart along the first direction.

[0084] In the technical solution of this embodiment, the active blade 21 moves along the first direction under the transmission of the first transmission component 11, and can drive the connecting rod 23 to move in the first direction together. Then the connecting rod 23 drives the multiple driven blades 22 to move together in the first direction, so that multiple blades are simultaneously transmitted through the first transmission component 11, so that they can all move in the first direction.

[0085] It should be emphasized that the rotating shafts of the multiple driven blades 22 can be all provided with the driven gear 17, so that the multiple driven blades 22 can swing along the first direction when moving in the first direction under the action of the driven rack 16. It can also be that some of them are provided with the driven gear 17 and the other part is not. When the driven gear 17 is partially provided, one and only one driven blade 22 can be provided with it among every two adjacent driven blades 22, or the driven blades 22 can be randomly provided with it, or it can be provided in the upper half of the connecting rod 23, and so on, which is not limited here.

[0086] The plurality of driven blades 22 are arranged at intervals along the first direction, so that each driven blade 22 can guide the airflow in a certain area, thereby avoiding excessive overlap of the active areas of the driven blades 22 and improving the wind guiding effect.

[0087] Since the driven gear 17 is provided on the rotating shaft of the active blade 21 and / or the driven blade 22, generally speaking, the diameter of the driven gear 17 is larger than the diameter of the rotating shaft. Therefore, when installing the active blade 21 and / or the driven blade 22, it is easy to interfere with other components due to the diameter of the driven gear 17, resulting in difficulty in installation.

[0088] Therefore, in order to facilitate the installation of the active blade 21 and / or the driven blade 22, the connecting rod 23 has a first side and a second side arranged relatively to each other along the second direction; the connecting rod 23 is provided with a plurality of rotating mounting grooves 231 extending along the second direction, the open end of the rotating mounting groove 231 is formed on the second side of the connecting rod 23, and the rotating mounting groove 231 penetrates the connecting rod 23 along the third direction; the rotating shafts of the active blade 21 and the plurality of driven blades 22 are respectively rotatably mounted on the plurality of rotating mounting grooves 231.

[0089] In the technical solution of this embodiment, since the open end of the rotating mounting groove 231 is formed on the second side of the connecting rod 23, during the installation of the active blade 21 and / or the driven blade 22, the rotating shaft can be inserted through the open end of the rotating mounting groove 231. Correspondingly, at this time, the rotating mounting groove 231 penetrates the connecting rod 23 along the third direction, and the driven gear 17 and the main body of the active blade 21 and / or the driven blade 22 can be arranged on both sides of the third direction of the connecting rod 23 to avoid interference with the connecting rod 23, thereby improving the ease of installation of the active blade 21 and / or the driven blade 22.
