[0053] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0054] The following describes the air guide device 10 of the air conditioner 100 and the air conditioner 100 having the same according to an embodiment of the present invention with reference to the accompanying drawings. Figure 1-3 As shown, the air conditioner 100 includes a housing 20 having an air outlet 201 , and the air guide device 10 is used to guide the airflow in the air duct of the air conditioner 100 to the indoor environment.

[0055] Reference Figure 6-Figure 8 As shown, the air guide device 10 of the air conditioner 100 according to the embodiment of the present invention may include an air guide plate assembly 1, an air guide blade assembly 2 and a connecting rod 3.

[0056] Specifically, the air guide plate assembly 1 is rotatably disposed at the air outlet 201 to open or cover the air outlet 201. The air guide plate assembly 1 has an installation space 1a (refer to Figure 8 As shown), the guide blade assembly 2 is multiple and is arranged in the length direction of the guide plate assembly 1 (refer to Figure 6 The guide vane assembly 2 is rotatably connected to the guide plate assembly 1 and is located on the side of the guide plate assembly 1 facing the air outlet 201. The connecting rod 3 is disposed in the installation space 1a. The connecting rod 3 is rotatably connected to the guide vane assembly 2 to drive the multiple guide vane assemblies 2 to rotate synchronously. It can be understood that in the present invention, multiple refers to two or more.

[0057] It should be noted that, refer to Figure 5 As shown, when the air guide plate assembly 1 opens the air outlet 201 to discharge air normally, the air guide blade assembly 2 can guide the airflow to enhance the air supply effect of the air conditioner 100. However, in the related art, since the connecting rod is arranged on the side of the air guide plate assembly facing the air outlet of the air conditioner, the connecting rod occupies a part of the position of the air guide blade assembly, resulting in the need to cut off a part of the air guide blade assembly, resulting in a small air guide area of ​​the air guide blade assembly. At the same time, when the air guide plate assembly is rotated to the position of opening the air outlet to discharge air normally, the connecting rod has the problem of blocking the wind, and the connecting rod can be seen by the user, and children may pull the connecting rod out of curiosity, which poses certain safety hazards, and the appearance of the air guide device is complicated and messy, affecting the user's experience.

[0058] The air guide device 10 of the air conditioner 100 according to the embodiment of the present invention, by arranging the connecting rod 3 in the installation space 1a, can overcome the wind blocking problem of the connecting rod 3 and reduce wind resistance when the air guide plate assembly 1 opens the air outlet 201 to supply air normally. The air guide area of ​​the air guide blade assembly 2 can be designed to be larger, which is beneficial to improving the air supply capacity of the air guide blade assembly 2, and at the same time is beneficial to reducing safety hazards and improving the appearance of the air guide device 10.

[0059] In some embodiments of the present invention, reference Figure 8 and Fig. 9 As shown, the air guide plate assembly 1 includes a first air guide plate 11 and a second air guide plate 12. The first air guide plate 11 is provided with a plurality of first air dispersion holes 111, and the second air guide plate 12 is provided with a plurality of second air dispersion holes 121. The second air guide plate 12 is located on a side of the first air guide plate 11 facing the air outlet 201. The second air guide plate 12 and the first air guide plate 11 are in the width direction of the air guide plate assembly 1 (refer to Figure 6 The second air guide plate 12 is connected to the middle part of the first air guide plate 11 in the F2 direction, and the second air guide plate 12 is spaced apart from the middle part of the first air guide plate 11 to define an installation space 1a, and the first air dispersion hole 111 and the second air dispersion hole 121 are respectively connected to the installation space 1a.

[0060] It is understandable that, referring to Figure 1 and Figure 8 As shown, when the air guide plate assembly 1 blocks the air outlet 201, the air flow blown out from the air supply duct 801 of the air conditioner 100 by the air guide blade assembly 2 is guided to the air guide plate assembly 1, and the air flow flows from the second air dispersion holes 121 of the second air guide plate 12 to the installation space 1a, and flows out through the first air dispersion holes 111 on the first air guide plate 11 to achieve the dispersion of the air flow blown out by the air conditioner 100, which is beneficial to achieve uniform and soft air outlet of the air conditioner 100, thereby achieving a windless effect.

[0061] In some optional embodiments of the present invention, referring to Figure 11-Figure 12 As shown, the air guide blade assembly 2 includes a louver 21 and a transmission member 23. The louver 21 is located on the side of the second air guide plate 12 facing the air outlet 201. The louver 21 can be generally in the shape of a sheet. The louver 21 has a pivot shaft 211. The second air guide plate 12 is provided with a pivot hole 122. The pivot shaft 211 passes through the pivot hole 122 and is rotatably matched with the pivot hole 122. The transmission member 23 is located in the installation space 1a. The transmission member 23 is fixedly connected to the part of the pivot shaft 211 passing through the pivot hole 122. The connecting rod 3 drives the louver 21 to rotate through the transmission member 23. It can be understood that by arranging the transmission member 23 in the installation space 1a, when the air guide plate assembly 1 opens the air outlet 201 to supply air normally, the wind shielding component of the connecting rod 3 can be reduced, and the air guide area of ​​the louver 21 can be designed to be larger, which is conducive to improving the air supply capacity of the louver 21, while helping to reduce safety hazards and improve the appearance of the air guide device 10.

[0062] In some optional embodiments of the present invention, referring to Figure 13-14 As shown, the transmission member 23 is a moving impeller 231, and the moving impeller 231 includes a moving hub 2311 and a plurality of moving blades 2313, and the plurality of moving blades 2313 are arranged at intervals in the circumferential direction of the moving hub 2311, and the moving hub 2311 is fixedly connected to the portion of the pivot shaft 211 that passes through the pivot hole 122, and the connecting rod 3 is rotatably connected to the moving blades 2313 to drive the moving impeller 231 and the louver 21 to rotate synchronously. For example, the connecting rod 3 is rotatably connected to one of the moving blades 2313 to drive the moving impeller 231 and the louver 21 to rotate synchronously, and the moving blade 2313 connected to the connecting rod 3 is provided with a first rotating shaft 23131, and the first rotating shaft 23131 is rotatably connected to the connecting rod 3.

[0063] It can be understood that when the air guide plate assembly 1 opens the air outlet 201, the louver 21 can guide the airflow to the air outlet 201, and the connecting rod 3 can drive the multiple impellers 231 to rotate. The rotation of the impellers 231 drives the corresponding louvers 21 to rotate, so as to achieve synchronization of multiple louvers 21 in the length direction of the air guide plate assembly 1 to adjust the air outlet direction, which is beneficial to ensure the wind guiding capacity and meet the different needs of users; when the air guide plate assembly 1 is blocked, the louver 21 guides the airflow to the impeller 231, and the multiple impellers 2313 spaced apart in the circumferential direction can break up the airflow, and the broken up airflow can flow out of the air guide device 10 through the second air dispersion hole 121 and the first air dispersion hole 111, thereby making the air outlet of the air conditioner 100 uniform and comfortable.

[0064] Of course, the present invention is not limited to this. For example, Fig.14 As shown, in some examples, the impeller 231 further includes an outer ring 2314, the impeller hub 2311 is installed in the outer ring 2314 and is spaced apart from the outer ring 2314, the impeller blades 2313 are connected between the outer peripheral wall of the impeller hub 2311 and the outer ring 2314, and the connecting rod 3 is connected to the outer ring 2314 of each impeller 231 to drive the multiple impellers 231 to rotate synchronously. This is conducive to improving the structural strength of the impeller 231 and ensuring the reliability of the connection between the connecting rod 3 and the impeller 231.

[0065] In some optional embodiments of the present invention, referring to Fig. 9 and Fig.14As shown, the moving hub 2311 is provided with a first fixing hole 2312, and the first fixing hole 2312 is a non-circular hole. The portion of the pivot shaft 211 that passes through the pivot hole 122 has a fixing portion 212 that is suitable for cooperating with the first fixing hole 2312, and the shape of the outer peripheral wall of the fixing portion 212 is adapted to the shape of the inner peripheral wall of the first fixing hole 2312. It can be understood that by making the first fixing hole 2312 a non-circular hole, when the fixing portion 212 cooperates with the first fixing hole 2312 to drive the moving impeller 231 to rotate, it is helpful to prevent the fixing portion 212 and the first fixing hole 2312 from sliding relative to each other in the circumferential direction, thereby ensuring the reliability of the operation of the louver 21. Optionally, refer to Fig. 9 As shown, the free end of the fixing portion 212 is provided with an anti-slip portion 213 , and the anti-slip portion 213 is suitable for abutting against a side wall of the moving hub 2311 to prevent the shutter 21 from slipping off the moving hub 2311 .

[0066] For example, refer to Fig.14 As shown, the first fixing hole 2312 can be formed as a flat hole with a roughly quadrilateral cross-section, and the shape of the outer circumferential wall of the fixing portion 212 is adapted to the shape of the inner circumferential wall of the first fixing hole 2312. A deformation groove 214 is also provided on the pivot shaft 211, and the deformation groove 214 passes through the first fixing hole 2312 and the anti-slip portion 213 in the axial direction of the pivot shaft 211, thereby enhancing the deformation ability of the pivot shaft 211 and facilitating the installation between the louver 21 and the moving hub 2311.

[0067] In some optional embodiments of the present invention, referring to Fig.16 As shown, a plurality of stationary impellers 123 are arranged on the second air guide plate 12, and the plurality of stationary impellers 123 are arranged one by one with the plurality of moving impellers 231. The stationary impeller 123 includes a stationary hub 123a and a plurality of stationary blades 124. The pivot hole 122 is arranged on the stationary hub 123a and penetrates the stationary hub 123a in the thickness direction of the stationary hub 123a. It can be understood that when the air guide plate assembly 1 is blocked, the louver 21 directs the airflow to the stationary impeller 123 and the moving impeller 231 in sequence, and the airflow can be dispersed twice, which is conducive to further improving the softness of the air outlet of the air conditioner 100. At the same time, when the moving impeller 231 is in different positions, the flow rate and flow rate of the airflow dispersed twice by the stationary impeller 123 and the moving impeller 231 will also change, which is conducive to enriching the air outlet form of the air guide device 10 and meeting the different needs of users.

[0068] Optional, see Fig.14As shown, the transmission member 23 is a transmission rod 232, one end of the transmission rod 232 is connected to the portion of the pivot shaft 211 passing through the pivot hole 122, and the connecting rod 3 is rotatably connected to the other end of the transmission rod 232. As a result, the structure is simple and compact. For example, one end of the transmission tube is provided with a second fixing hole 2321, the second fixing hole 2321 is non-circular, the second fixing hole 2321 is fixedly connected to the portion of the pivot shaft 211 passing through the pivot hole 122, and the other end of the transmission rod 232 is provided with a second rotating shaft 2322, and the second rotating shaft 2322 is rotatably connected to the connecting rod 3.

[0069] In some examples, reference Fig.14 As shown, there are multiple transmission parts 23, a part of the multiple transmission parts 23 is formed as an impeller 231, and the remaining part of the transmission part 23 is a transmission rod 232. The multiple impellers 231 and the multiple transmission rods 232 are arranged alternately in the up and down directions. In this way, the connecting rod 3 can drive the impeller 231 and the transmission rod 232 to rotate at the same time, and the rotation of the impeller 231 and the transmission rod 232 respectively drives the corresponding louvers 21 to rotate, thereby realizing multiple synchronous up and down rotations to change the wind guide effect.

[0070] In some optional embodiments of the present invention, referring to Fig.15 As shown, the second air guide plate 12 is provided with a slide groove 125, the slide groove 125 penetrates the second air guide plate 12 in the thickness direction of the second air guide plate 12 and extends in the length direction of the air guide plate assembly 1, and the air guide device 10 also includes a slider 4 and a driving assembly 5, the slider 4 is slidably matched with the slide groove 125, and the driving assembly 5 is connected to the connecting rod 3 through the slider 4. It can be understood that when the rotation angle of the louver 21 needs to be adjusted, the driving assembly 5 can drive the slider 4 to move along the length direction of the air guide plate assembly 1, so as to drive the connecting rod 3 to move and then drive the multiple louvers 21 to rotate synchronously, thereby, the structure is simple, and it is conducive to improving the reliability of ensuring the movement of the connecting rod 3.

[0071] In some specific embodiments of the present invention, Fig.11 and Fig.12 As shown, the connecting rod 3 is detachably connected to the slider 4. For example, the connecting rod 3 can be connected to the slider 4 by a buckle, a threaded fastener or a riveting connection, thereby facilitating the installation and disassembly of the connecting rod 3 and the slider 4 and facilitating the cleaning of the connecting rod 3 and the slider 4 by making the connecting rod 3 and the slider 4 detachably connected.

[0072] In some specific embodiments of the present invention, referring to Fig.15 and Fig.14 As shown, the slider 4 is provided with a first sliding structure 41, and the connecting rod 3 is provided with a second sliding structure 31, and the first sliding structure 41 and the second sliding structure 31 are slidably matched in the width direction of the air guide plate assembly 1. Fig.13As shown, the first sliding structure 41 is a through slot extending in the width direction of the air deflector assembly 1, and the second sliding structure 31 is formed as a connecting column, which is slidably disposed in the through slot. Therefore, when the driving mechanism drives the slider 4 to move, the connecting rod 3 can move relative to the slider 4 along the length direction of the air deflector assembly 1 and along the width direction of the air deflector assembly 1, which is conducive to preventing the connecting rod 3 from getting stuck during the up and down movement process, and ensuring the reliability of the air deflector device 10.

[0073] In some embodiments of the present invention, reference Figure 3 and Figure 5 As shown, the driving assembly 5 includes: a driving motor 51, a gear member 52 and a pull rod 53. One end of the pull rod 53 is connected to the slider 4, and the other end of the pull rod 53 is provided with a rack structure 54. The rack structure 54 extends in the length direction of the air deflector assembly 1. The driving motor 51 is provided on the housing 20 to drive the gear member 52 to rotate. The gear member 52 is meshed with the rack structure 54 so that the pull rod 53 moves in the length direction of the air deflector assembly 1. For example, the driving motor 51 is provided below the air deflector assembly 1, and the lower end of the air deflector assembly 1 is provided with a first connecting plate 114. The first connecting plate 114 is provided with a first avoidance hole 1141. The pull rod 53 is inserted into the first avoidance hole 1141 and extends in the up-down direction. The central axis of the pull rod 53 is on the same straight line as the rotation center line of the air deflector assembly 1 and the air guide vane assembly 2 as a whole. It can be understood that the drive motor 51 drives the gear part 52 to rotate, the gear part 52 engages with the rack structure 54 to drive the pull rod 53 to move along the length direction of the air guide plate assembly 1, the pull rod 53 pulls the slider 4 to move to drive the connecting rod 3 to move, and the movement of the connecting rod 3 drives multiple air guide blade assemblies 2 to rotate synchronously to change the air guide effect.

[0074] Optionally, in some specific examples, refer to Figure 4 As shown, the rack structure 54 includes a plurality of annular teeth 541, which are spaced apart in the length direction of the pull rod 53. Thus, the structural strength of the rack structure 54 can be improved, which is conducive to ensuring reliable meshing of the rack structure 54 and the gear member 52.

[0075] In some embodiments of the present invention, reference Figure 4 , Fig. 9 and Fig.10 As shown, the pull rod 53 is detachably connected to the slider 4.
