[0028] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] This application provides an air guiding device to solve the technical problem that existing air guiding devices require an additional motor drive, resulting in high costs. The following description is in conjunction with the accompanying drawings.

[0031] In the embodiments of this application, such as Figures 1 to 3 As shown, the air guiding device 10 includes a first air guiding plate 11, a second air guiding plate 12, a first transmission member 13, a second transmission member 14, and a driving member 15. The first transmission member 13 has a toothed portion 131 and a gear portion 132. The second transmission member 14 meshes with the gear portion 132. The first transmission member 13 is connected to the first air guiding plate 11 to drive the first air guiding plate 11 to rotate. The second transmission member 14 is connected to the second air guiding plate 12 to drive the second air guiding plate 12 to rotate. The driving member 15 is connected to the first transmission member 13 to drive the first air guiding plate 12 to rotate. The first transmission member 13 rotates in either a first or second direction. When the first transmission member 13 rotates in the first direction, it drives the first air guide plate 11 to rotate in the first direction. The toothed part 131 cooperates with the second transmission member 14 to keep the second air guide plate 12 stationary while the first air guide plate 11 rotates in the first direction. When the first transmission member 13 rotates in the second direction, the second transmission member 14 cooperates with the gear part 132 to make the first air guide plate 11 and the second air guide plate 12 rotate synchronously in the second direction.

[0032] It should be noted that the common air guide plate structure on the market is usually a simple and reliable single air guide plate structure. Since the air guiding angle of the single air guide plate structure is limited, related technologies use a double air guide plate structure to improve the air delivery angle. However, this method requires an additional motor drive, which results in a higher cost for the air guide plate structure.

[0033] The air guiding device 10 provided in this application has a toothed portion 131 and a gear portion 132 in the first transmission member 13. When the first transmission member 13 rotates in the first direction, it drives the first air guiding plate 11 to rotate in the first direction. At this time, the second transmission member 14 cooperates with the toothed portion 131 of the first transmission member 13. During the rotation of the first air guiding plate 11, the second air guiding plate 12 remains stationary, and the air guiding device 10 is guided by the first air guiding plate 11. When the first transmission member 13 rotates in the second direction, it drives the first air guiding plate 11 to rotate in the second direction. At this time, the second transmission member 14 cooperates with the gear portion 132 of the first transmission member 13. The first air guiding plate 11 and the second air guiding plate 12 rotate synchronously, and the air guiding device 10 is guided by the first air guiding plate 11 and the second air guiding plate 12 together.

[0034] That is, in this application, the first transmission component 13 is connected to the drive component 15, and the second transmission component 14 can cooperate with the toothed part 131 or the gear part 132 of the first transmission component 13 to realize different air guiding modes. Only one drive component 15 is needed to realize different air guiding modes of the air guiding device 10. The structure is simple and the production cost of the air guiding device 10 is reduced.

[0035] For details, please refer to Figure 2 , Figure 5 and Figure 6 The first direction and the second direction are opposite directions. For example, the first direction is... Figure 5 The clockwise direction in the middle, the second direction is Figure 6 The air guide device 10 is in the counterclockwise direction. When the air guide device 10 is in the closed state, the second transmission member 14 meshes with the edge of the gear part 132. When the driving member 15 drives the first transmission member 13 to rotate in the clockwise direction, the transmission chain between the first transmission member 13 and the second transmission member 14 breaks. The first transmission member 13 drives the first air guide plate 11 to rotate in the clockwise direction at a certain angle, while the second transmission member 14 is stationary because it is not driven by any force. This achieves asynchronous rotation of the first air guide plate 11 and the second air guide plate 12, effectively expanding the air guide angle of the first air guide plate 11 and improving the air guide effect of the air guide device 10.

[0036] Further, please refer to Figure 3 Since the driving component 15 directly drives the first transmission component 13 to rotate, that is, the first transmission component 13 is the driving wheel, setting the toothed part 131 on the first transmission component 13 is conducive to the second transmission component 14 and the toothed part 131 to achieve precise cooperation, ensuring that when the first transmission component 13 rotates in the first direction, the second transmission component 14 can disengage from the gear part 132 of the first transmission component 13, thereby improving the reliability of the operation of the first transmission component 13 and the second transmission component 14.

[0037] Optionally, in one embodiment, the first transmission member 13 is an incomplete internal gear. Specifically, the first transmission member 13 is disc-shaped. Since the first transmission member 13 is an internal gear, when the first transmission member 13 meshes with the second transmission member 14, the second transmission member 14 can rotate in the same direction as the first transmission member 13, realizing the synchronous rotation of the first air guide plate 11 and the second air guide plate 12. When the second transmission member 14 disengages from the first transmission member 13, that is, when the second transmission member 14 engages with the missing tooth portion 131 of the first transmission member 13, the first transmission member 13 rotates while the second transmission member 14 remains stationary, realizing the independent air guidance of the first air guide plate 11.

[0038] Optionally, in one embodiment, please refer to Figure 3 and Figure 4 The second transmission component 14 includes a gear and a first connecting rod 141, one end of which is connected to the drive component 15.

[0039] Specifically, the first connecting rod 141 is block-shaped, with one end fixed to the center of the gear and the other end having a mounting hole. The driving component 15 includes an output shaft 151, and the first connecting rod 141 is fixed to the output shaft 151 through the mounting hole. Simultaneously, the center of the first transmission component 13 also has a mounting hole, through which it is fixed to the output shaft 151. This ensures that the rotation center of the second transmission component 14 coincides with the center of the first transmission component 13. When the first transmission component 13 rotates, the second transmission component 14 can engage or disengage with it, allowing the second transmission component 14 to produce intermittent motion. This enables the first air guide plate 11 and the second air guide plate 12 to rotate in different combinations, improving the comfort of the air guiding device 10.

[0040] Furthermore, the gear of the second transmission member 14 can also be an incomplete gear. When the first transmission member 13 rotates in the second direction, the gears of the first transmission member 13 and the second transmission member 14 mesh, thereby driving the first air guide plate 11 and the second air guide plate 12 to rotate synchronously in the second direction. At this time, the maximum rotation angle of the first transmission member 13 and the second transmission member 14 is 110°. Therefore, the second transmission member 14 can be set as an incomplete gear to achieve the same effect. As for the incomplete gear ratio of the second transmission member 14, it can be set according to the actual situation, and this application does not impose any restrictions.

[0041] Optionally, in one embodiment, please refer to Figure 7 The second transmission component 14 is a cam, with one end connected to the drive component 15 and the other end engaging with the first transmission component 13. Specifically, the two ends of the cam are semicircles of different sizes. The larger diameter semicircle has teeth that mesh with the gear portion 132 of the first transmission component 13 to achieve rotation. The smaller diameter end has a mounting hole that connects to the output shaft 151 of the drive component 15 for fixation. By setting the second transmission component 14 as a cam that engages with the first transmission component 13, the first air guide plate 11 and the second air guide plate 12 can rotate in different combinations, improving the comfort of the air guiding device 10.

[0042] Optionally, in one embodiment, please refer to Figures 1 to 3 The first air guide plate 11 is provided with a second connecting rod 111, and the second air guide plate 12 is provided with a third connecting rod 121. The second connecting rod 111 is connected to the first transmission component 13, and the third connecting rod 121 is connected to the second transmission component 14.

[0043] Specifically, the second connecting rod 111 is arranged perpendicularly to the first air guide plate 11. The second connecting rod 111 can be fixed to the first air guide plate 11 by welding, gluing or integral molding. The second connecting rod 111 is provided with a first shaft hole, which is used to connect to the output shaft 151 of the driving member 15. The output shaft 151 extends along the length direction of the first air guide plate 11. The second connecting rod 111 is connected to the first transmission member 13 through the output shaft 151. By starting the driving member 15, the first transmission member 13 and the first air guide plate 11 can be driven to rotate.

[0044] The third link 121 can be fixed to the second air guide plate 12 by welding, gluing or integral molding, and the third link 121 is oriented toward the second link 111. The third link 121 is provided with a second shaft hole, which is used to connect with the shaft of the second transmission member 14, thereby driving the second air guide plate 12 to rotate through the second transmission member 14. Since the second transmission member 14 meshes with the gear part 132 of the first transmission member 13, the first air guide plate 11 and the second air guide plate 12 can rotate synchronously.

[0045] Optionally, in one embodiment, please refer to Figure 2 and Figure 5 The first air guide plate 11 and the second air guide plate 12 are connected by a spring 16.

[0046] Understandably, when the first transmission member 13 rotates along the first direction, the second guide plate 12 remains stationary during the rotation of the first guide plate 11 along the first direction because the second transmission member 14 engages with the toothed portion 131 of the first transmission member 13. By providing a spring 16 at the contact point between the first guide plate 11 and the second guide plate 12, the spring 16 is in a stretched state during the rotation of the first guide plate 11. At this time, the spring 16 provides an upward traction force to the second guide plate 12, which can offset part of the gravity, preventing the second guide plate 12 from falling under gravity, thereby improving the reliability of the entire air guiding device 10. Of course, to maintain good reliability, the number of springs 16 can be two or more. When there are two springs 16, they can be located at opposite ends of the first guide plate 11 and the second guide plate 12, respectively.

[0047] Optionally, in one embodiment, to save transmission space and ensure structural reliability, the transmission ratio between the first transmission member 13 and the second transmission member 14 is 2:1; the ratio of the missing tooth portion 131 to the gear portion 132 of the first transmission member 13 is 4:6, that is, the incomplete tooth ratio of the first transmission member 13 is 0.6. In this application, the transmission ratio of the first transmission member 13 and the second transmission member 14, as well as the incomplete tooth ratio of the first transmission member 13, can be adjusted according to actual needs, for example, according to the size of the air outlet 21 of the air conditioner. This application does not impose any limitations on this adjustment.

[0048] This application also provides an air conditioner, which includes a housing 20 and an air guide device 10. The housing 20 is provided with an air outlet 21, and the air guide device 10 is rotatably installed at the air outlet 21. The specific structure of the air guide device 10 is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0049] The air outlet 21 is located on the lower front side of the indoor unit of the air conditioner and is rectangular in shape. By rotating the air guide device 10, the air outlet angle of the indoor unit can be changed, thereby increasing the air delivery distance of the indoor unit. The length and width of the air guide device 10 are slightly smaller than the length and width of the air outlet 21. When the indoor unit of the air conditioner is turned off, the air guide device 10 can seal the air outlet 21.

[0050] The first air guide plate 11 and the second air guide plate 12 are arranged in an arc shape. The cross-section of the lower front side of the air conditioner indoor unit is usually arc-shaped. Therefore, setting the first air guide plate 11 and the second air guide plate 12 to be arc-shaped can ensure the appearance of the air conditioner indoor unit and seal the air outlet 21. At the same time, the arc-shaped air guide plate is conducive to air guidance and can increase the air delivery angle.

[0051] Optionally, in one embodiment, please refer to Figure 8 The housing 20 is provided with a first adsorption member 22, and the second air guide plate 12 is provided with a second adsorption member 122. When the first transmission member 13 rotates in the first direction, the first adsorption member 22 and the second adsorption member 122 cooperate to fix the second air guide plate 12 at the air outlet 21.

[0052] Specifically, the first adsorption member 22 is disposed at the top of the air outlet 21, and the second adsorption member 122 is disposed on the side of the second air guide plate 12 away from the first air guide plate 11. It is understood that when the first transmission member 13 rotates in the first direction, because the second transmission member 14 engages with the toothed portion 131 of the first transmission member 13, the second air guide plate 12 remains stationary during the rotation of the first air guide plate 11 in the first direction. The first adsorption member 22 can provide an attractive force to the second adsorption member 122 to fix the second air guide plate 12 at the air outlet 21, preventing the second air guide plate 12 from falling downwards due to gravity, thus preventing the second air guide plate 12 from completely closing with the top of the air outlet 21.

[0053] This application provides a first adsorption element 22 on the top of the air outlet 21 and a second adsorption element 122 on the second air guide plate 12. The first adsorption element 22 can adsorb with the second adsorption element 122 to reduce the gap between the second air guide plate 12 and the top of the air outlet 21, thereby beautifying the appearance of the air conditioner indoor unit and improving the reliability of the air guide device 10.

[0054] Optionally, in one embodiment, the first adsorption element 22 is metal, and the second adsorption element 122 is a magnet. Specifically, the first adsorption element 22 can be an iron sheet, a cobalt sheet, a nickel sheet, etc. By setting the second adsorption element 122 as a magnet, the second air guide plate 12 can be adsorbed at the air outlet 21, preventing the second air guide plate 12 from falling off while stationary. In this application, the first adsorption element 22 and the second adsorption element 122 can both be set as magnets, or the first adsorption element 22 can be set as a magnet and the second adsorption element 122 can be set as metal; this is not limited here.

[0055] It is understandable that the indoor unit of the air conditioner has a cooling mode and a heating mode. In order to improve the user experience in the cooling and heating modes, in the cooling mode, the air guide device 10 usually needs to push the cold air forward as much as possible, while in the heating mode, the air guide device 10 usually needs to push the hot air downward as much as possible.

[0056] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the air guide device 10 when the indoor unit of an air conditioner is in heating mode. Figure 6 This is a schematic diagram of the air guide device 10 when the indoor unit of the air conditioner is in cooling mode. When the indoor unit of the air conditioner is in the off state, the first air guide plate 11 and the second air guide plate 12 together constitute part of the appearance of the indoor unit of the air conditioner. At this time, the second transmission member 14 meshes with the edge of the gear part 132, that is, the second transmission member 14 is located at the critical position between the gear part 132 and the toothed part 131.

[0057] When the indoor unit of the air conditioner receives the instruction for heating mode, please refer to [link / reference needed]. Figure 5 The driving component 15 drives the first transmission component 13 to rotate in the first direction. The second transmission component 14 cooperates with the toothed part 131 of the first transmission component 13. During the rotation of the first air guide plate 11 in the first direction, the second air guide plate 12 remains stationary. The air conditioner indoor unit guides the air through the first air guide plate 11, thereby realizing the downward airflow for heating of the air conditioner indoor unit. In the heating mode, the angle range of the first transmission component 13 rotating in the first direction is 0 to 110°.

[0058] When the indoor unit of the air conditioner receives the instruction for heating mode, please refer to [link / reference needed]. Figure 6The driving component 15 drives the first air guide plate 11 to rotate in the second direction to achieve a reset. Then, the second transmission component 14 engages with the gear portion 132 of the first transmission component 13, causing the first air guide plate 11 and the second air guide plate 12 to rotate synchronously in the second direction. The indoor unit of the air conditioner is guided by the first air guide plate 11 and the second air guide plate 12, thereby achieving forward airflow for cooling. In cooling mode, the rotation angle of the first air guide plate 11 and the second air guide plate 12 in the second direction ranges from 0 to 110°. By achieving airflow at different angles in cooling and heating modes, the comfort of the indoor unit of the air conditioner is improved, and the increased airflow angle makes the comfort of the air conditioner even better in both cooling and heating modes.
