[0061] The following describes embodiments of the present invention in detail. 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0062] The air guide plate assembly 10 , the air guide mechanism 100 , and the air conditioner 1000 according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0063] Reference Figure 1-Figure 3 As shown, according to an embodiment of the present invention, the air deflector assembly 10 is used for an air conditioner 1000, and the air conditioner 1000 includes a housing 200, the housing 200 is provided with an air outlet 2001, and the housing 200 has an air outlet channel 2002 connected to the air outlet 2001 (refer to FIG. Figure 4 ), the air guide plate assembly 10 can be movably provided at the air outlet 2001 to open or close the air outlet 2001.

[0064] For example, the air deflector assembly 10 is rotatably provided at the air outlet 2001, or the air deflector assembly 10 is movably provided at the air outlet 2001, or the air deflector assembly 10 is both movably and rotatably provided at the air outlet 2001 (see Figure 16 ).

[0065] Reference Figure 5-Figure 7 As shown, the air guide plate assembly 10 includes a first air guide plate 1, a diverter plate 2, and a second air guide plate 3. For example, the first air guide plate 1 and the diverter plate 2 can be stacked. The first air guide plate 1 is provided with a first air dispersion hole 11, and the diverter plate 2 is provided with spaced diverter holes 21 and a guide column 22. The diverter plate 2 is movably provided on the first air guide plate 1 between a first position and a second position. For example, the diverter plate 2 can be rotatably or movably provided on the first air guide plate 1 between the first position and the second position. In the first position, the guide column 22 cooperates with the first air dispersion hole 11 to close the first air dispersion hole 11. In the second position (refer to Figure 7 ), the guide column 22 opens the first air diffusion hole 11 so that the diverter hole 21 is connected to the first air diffusion hole 11.

[0066] It can be understood that when the diverter plate 2 is in the first position, the guide column 22 closes the first air dispersion hole 11, and the airflow discharged from the air outlet 2001 cannot flow out through the first air dispersion hole 11, and the airflow can flow on the surface of the air guide plate assembly 10. When the diverter plate 2 is in the second position, the guide column 22 opens the first air dispersion hole 11, and the airflow discharged from the air outlet 2001 can be dispersed through the first air dispersion hole 11 and the diverter hole 21 and then flow out, so that the wind guiding function of the air guide plate assembly 10 can be changed by changing the position of the diverter plate 2, so that the air conditioner 1000 can have multiple air supply modes, which is conducive to meeting the usage needs of different users.

[0067] In view of this, according to the air guide plate assembly 10 of an embodiment of the present invention, when the diverter plate 2 is in the first position, the guide column 22 closes the first air dispersion hole 11, and the airflow discharged from the air outlet 2001 cannot flow out through the first air dispersion hole 11, and the airflow can flow on the surface of the air guide plate assembly 10; when the diverter plate 2 is in the second position, the guide column 22 opens the first air dispersion hole 11, and the airflow discharged from the air outlet 2001 can be dispersed through the first air dispersion hole 11 and the diverter hole 21 and then flow out, so that the air guiding function of the air guide plate assembly 10 can be changed by changing the position of the diverter plate 2, so that the air conditioner 1000 can have a variety of air supply modes, which is conducive to meeting the usage needs of different users.

[0068] Optionally, refer to Figure 7-Figure 9 As shown, there are multiple guide posts 22 and multiple first air dispersion holes 11, and the multiple guide posts 22 are arranged in a one-to-one correspondence with the multiple first air dispersion holes 11. Therefore, in the second position, the first air guide plate 1 can improve the air flow dispersion effect, which is conducive to achieving a cool but windless air supply effect when the air conditioner 1000 is cooling.

[0069] In some examples, reference Figure 10-11 As shown, the diverter plate 2 is a grid plate and includes a plurality of diverter holes 21, and the plurality of diverter holes 21 are arranged in multiple rows and columns (refer to Figure 13 As shown), thus, in the second position, the air flow breaking effect of the diverter plate 2 can be improved, which is beneficial to further improve the wind dispersion effect of the air guide plate assembly 10 and realize softened air supply.

[0070] In some embodiments of the present invention, reference Figure 7 As shown, the diverter plate 2 is movably mounted on the first air guide plate 1 along the length of the diverter hole 21. In other words, the diverter plate 2 is movably mounted on the first air guide plate 1 along the axial direction of the diverter hole 21. This facilitates the mating and disengagement of the guide post 22 and the diverter hole 21, thereby improving the reliability of the mating between the diverter plate 2 and the first air guide plate 1.

[0071] In some embodiments of the present invention, reference Figure 7 As shown, the air guide plate assembly 10 includes: a driving device 4, the driving device 4 includes a driving motor 41, a gear member 42 and a rack structure 43, the rack structure 43 is provided on the diverter plate 2 (refer to Figure 11), and the rack structure 43 extends along the length of the diverter hole 21. The drive motor 41 is provided on the first air guide plate 1 to drive the gear member 42 to rotate, and the gear member 42 meshes with the rack structure 43. It will be understood that the motor shaft of the drive motor 41 is connected to the gear member 42, and the gear member 42 meshes with the rack structure 43. Driven by the drive motor 41, the drive motor 41 drives the gear member 42 to rotate, and the gear member 42 meshes with the rack structure 43 to drive the rack structure 43 and the diverter plate 2 to move along the length of the diverter hole 21. Therefore, through the meshing of the gear member 42 and the rack structure 43, the movement of the diverter plate 2 is smooth and stable, and the stroke of the first air guide plate 1 is easily controlled, thereby achieving high reliability and low cost.

[0072] Of course, the present invention is not limited thereto, and the driving device 4 may also be a screw drive mechanism, and the diverter plate 2 is connected to the screw and moves with the screw. The structure of the screw drive mechanism is prior art and will not be described in detail here.

[0073] In some embodiments of the present invention, reference Figure 7 As shown, one of the first air guide plate 1 and the diverter plate 2 is provided with a guide groove 23 (refer to Figure 11 ), the guide groove 23 extends in the length direction of the diverter hole 21, and the other of the first air guide plate 1 and the diverter plate 2 is provided with a guide block 12 (refer to Figure 9 ), the guide groove 23 slidably engages with the guide block 12. For example, the first air guide plate 1 is provided with a guide groove 23, and the diverter plate 2 is provided with a guide block 12 adapted to engage with the guide groove 23; or in another example, the first air guide plate 1 is provided with a guide block 12, and the diverter plate 2 is provided with a guide groove 23 adapted to engage with the guide block 12. It will be appreciated that the sliding engagement between the guide block 12 and the guide groove 23 can improve the reliability of the movable engagement between the diverter plate 2 and the first guide plate.

[0074] In some embodiments, reference Figure 8 and Figure 9 As shown, two guide blocks 12 are provided on the inner side wall of the first air guide plate 1. Figure 9 and Figure 11 As shown, two guide grooves 23 are provided on the diverter plate 2, and the two guide grooves 23 correspond to the two guide blocks 12 one by one. Optionally, the guide blocks 12 are formed into a columnar shape, and two connecting ears are provided on the drive motor 41. The two connecting ears are connected to the two guide blocks 12 one by one through threaded fasteners. Thus, the structure is simple and is conducive to improving the movement stability of the first air guide plate 1.

[0075] For example, in one embodiment of the present invention, referring to Figure 12-13As shown, a avoidance hole 24 is provided on the side wall of the diverter plate 2, and a rack structure 43 is provided on a portion of the inner peripheral wall of the avoidance hole 24. The avoidance hole 24 is located between the two guide grooves 23, thereby enabling reliable installation of the rack structure 43, and the structure is compact, which is conducive to reducing the volume of the air guide plate assembly 10.

[0076] In some embodiments of the present invention, reference Figure 7 As shown, the second air guide plate 3 is provided with a second air dispersion hole 31. In the flow direction of the airflow, the second air guide plate 3 is located at the downstream end of the first air guide plate 1. The second air guide plate 3 is connected to the first air guide plate 1 to define an insulation space 32, and the diverter plate 2 can be movably arranged in the insulation space 32. It can be understood that by defining an insulation space 32 between the first air guide plate 1 and the second air guide plate 3, the temperature difference between the outer surface of the second air guide plate 3 and the indoor space can be reduced, which is conducive to avoiding condensation, preventing condensation water from dripping onto the ground, and reducing installation hazards. At the same time, by arranging the diverter plate 2 in the insulation space 32, it is conducive to ensuring the reliability of the operation of the diverter plate 2, and when the diverter plate 2 is in the second position, the airflow discharged from the air outlet 2001 can flow into the insulation space 32 through the first air dispersion hole 11, and the guide column 22 of the diverter plate 2 can disperse the airflow, and then divert it through the diversion hole 21, which plays a role in breaking up the airflow. The dispersed air is then diffused to the outdoors through the second air dispersion hole 31 on the second air guide plate 3, reducing the wind speed, thereby further achieving the effect of softening the air outlet.

[0077] In some embodiments, the second air guide plate 3 is provided with a plurality of second air dispersion holes 31 , which are arranged in multiple rows and columns, thereby further improving the air dispersion effect of the second air guide plate 3 .

[0078] In some embodiments of the present invention, reference Figure 7 As shown, the side surface of the first air guide plate 1 facing the air outlet 2001 includes a first surface 1a and a second surface 1b in the width direction of the first air guide plate 1, one end of the first surface 1a is connected to one end of the second surface 1b, and the first surface 1a and the second surface 1b both extend toward the side surface of the second air guide plate 3 away from the air outlet 2001. For example, Figure 7 As shown, the first surface 1 a is located above the second surface 1 b.

[0079] It can be understood that when the air guide plate assembly 10 opens the air outlet 2001 and the upper and lower sides of the air guide plate assembly 10 are both outflowing, when the diverter plate 2 is in the first position, the guide column 22 cooperates with the first air dispersion hole 11 to close the first air dispersion hole 11, the first surface 1a and the second surface 1b are both air guide surfaces, and when the upper and lower sides of the air outlet 2001 are both outflowing, the first surface 1a and the second surface 1b are both windward surfaces and guide the airflow, and the first surface 1a and the second surface 1b divide the air outlet end of the air outlet channel 2002 into an upper air outlet portion 2003 and a lower air outlet portion 2004 (refer to Figure 7 As shown), the airflow flowing out from the upper air outlet 2003 can form a Coanda airflow along the ceiling, and the airflow flowing out from the lower air outlet 2004 can form another Coanda airflow along the wall. The two airflows realize a dual-flow mode, that is, a surround airflow.

[0080] When the diversion module moves from the first position to the second position, the guide column 22 opens the diversion hole 21, and the airflow discharged from the air outlet 2001 can also flow into the insulation space 32 through the first air dispersion hole 11. The guide column 22 of the diversion plate 2 can disperse the airflow, and then divert it through the diversion hole 21, which plays the role of breaking up the airflow. The broken air is then dispersed and diffused to the outdoors again through the second air dispersion hole 31 on the second air guide plate 3, reducing the wind speed, thereby realizing a multi-dimensional Coanda airflow that combines the surrounding airflow and the central windless diffusion airflow, achieving a cool and windless effect when the air conditioner 1000 is cooling.

[0081] Optionally, refer to Figure 7 As shown, the shapes of the matching surfaces of the diverter plate 2 and the first air guide plate 1 match each other, so that when the diverter plate 2 is in the first position, it is beneficial to increase the matching area between the diverter plate 2 and the first air guide plate 1 and improve the sealing matching effect.

[0082] In some embodiments of the present invention, reference Figure 7 As shown, in the second position, the distance between the guide column 22 and the first air dispersion hole 11 is L, and L satisfies: 2mm≤L≤8mm. In other words, L can take any value between 2mm and 8mm. For example, L can take a value of 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, or 8mm. Thus, on the one hand, the value of L is not too small, thereby ensuring the spacing between the guide column and the first air dispersion hole 11, thereby ensuring the air guiding effect of the guide column and the diversion effect of the diversion hole 21. On the other hand, the value of L is not too large, thereby ensuring that the volume of the air deflector assembly 10 is not too large, which is conducive to miniaturizing the air deflector assembly 10 and reducing the space occupied by the air deflector assembly 10.

[0083] In some embodiments of the present invention, reference Figure 9As shown, the equivalent diameter of the first air diffusion holes 11 is 2 mm to 5 mm. In other words, the equivalent diameter of the first air diffusion holes 11 can be any value within the range of 2 mm to 5 mm. For example, the equivalent diameter of the first air diffusion holes 11 can be 2 mm, 2.5 mm, 3.5 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm.

[0084] For example, the first air dispersion holes 11 can be formed in an elliptical, polygonal, or circular shape. The equivalent diameter of the first air dispersion holes 11 refers to the diameter of a circle with the same cross-sectional area as the first air dispersion holes 11. This prevents the equivalent diameter of the first air dispersion holes 11 from being too small, thereby facilitating the flow of air through the first air guide plate 1. Furthermore, it prevents the equivalent diameter of the first air dispersion holes 11 from being too large, thereby ensuring the effective air dispersion of the first air dispersion holes 11.

[0085] Reference Figure 1-Figure 3 As shown, the air guide mechanism 100 according to an embodiment of the present invention includes: an air guide plate assembly 10 according to the above embodiment of the present invention and a driving mechanism 20, the driving mechanism 20 is connected to the air guide plate assembly 10 to drive the air guide plate assembly 10 to open or close the air outlet 2001.

[0086] According to the air guide mechanism 100 of the embodiment of the present invention, by setting the air guide plate assembly 10 according to the above-mentioned embodiment of the present invention, the air guiding function of the air guide plate assembly 10 can be changed by changing the position of the diverter plate 2, so that the air conditioner 1000 can have multiple air supply modes, which is conducive to meeting the usage needs of different users.

[0087] In some embodiments of the present invention, reference Figure 16 and Figure 17 As shown, the driving mechanism 20 includes: a first connecting rod 201, a first driving assembly 202, a second connecting rod 203 and a second driving assembly 204. The first connecting rod 201 is movably arranged in the housing 200 along the extension direction of the air outlet channel 2002. The first driving assembly 202 is arranged on the housing 200. The first driving assembly 202 is connected to the first connecting rod 201 to drive the first connecting rod 201 to move. One end of the second connecting rod 203 is connected to the end of the first connecting rod 201 near the air outlet 2001. One end is rotatably connected, and the other end of the second connecting rod 203 extends toward the air outlet 2001. The air guide plate assembly 10 is non-movably connected to the end of the second connecting rod 203 away from the first connecting rod 201 to open or close the air outlet 2001. The second driving assembly 204 is arranged on the shell 200, and the second driving assembly 204 is connected to the second connecting rod 203 to drive the second connecting rod 203 to rotate relative to the first connecting rod 201, and the second driving assembly 204 and the second connecting rod 203 can slide relative to each other.

[0088] like Figure 16-21 As shown, in one embodiment of the present invention, Figure 13 As shown, when the first connecting rod 201 and the second connecting rod 203 are in the initial position, the first connecting rod 201 is located at a relatively inner position in the housing 200, the first connecting rod 201 and the second connecting rod 203 extend along the extension direction of the air outlet channel 2002, and the air guide plate assembly 10 closes the air outlet 2001, wherein, when the diverter plate 2 is in the first position, the guide column 22 cooperates with the first air dispersion hole 11 to close the first air dispersion hole 11, thereby facilitating the prevention of foreign matter from flowing into the air conditioner 1000 through the first air dispersion hole 11; when the diverter plate 2 is in the second position (refer to Figure 7 As shown in the figure, the guide column 22 opens the first air dispersion hole 11 to connect the diverter hole 21 with the first air dispersion hole 11. The airflow discharged from the air outlet 2001 is dispersed through the first air dispersion hole 11 and the diverter hole 21 and then flows out. This has a good effect on dispersing the airflow, can reduce the wind speed, and make the airflow slowly diffuse into the room, so that the air conditioner 1000 can achieve a completely windless air outlet.

[0089] like Figure 17 As shown, the first driving assembly 202 drives the first connecting rod 201 to move a certain distance toward the air outlet 2001, the second driving assembly 204 does not work, the second connecting rod 203 moves a certain distance toward the air outlet 2001 along with the first connecting rod 201, and the second connecting rod 203 slides relative to the second driving assembly 204, the air guide plate assembly 10 opens the air outlet 2001, and when the diverter plate 2 is in the first position, the guide column 22 cooperates with the first air dispersion hole 11 to close the first air dispersion hole 11, and the air guide plate assembly 10 divides the air outlet end of the air outlet channel 2002 into an upper air outlet portion 2003 and a lower air outlet portion 2004 (refer to Figure 4 As shown), the airflow flowing out from the upper air outlet 2003 can form a Coanda airflow along the ceiling, and the airflow flowing out from the lower air outlet 2004 can form another Coanda airflow along the wall, and the two airflows realize a dual-flow mode, i.e., surround airflow, which is beneficial to ensure the air volume and improve the user's wind feeling experience especially when the air conditioner is cooling; when the diverter plate 2 moves from the first position to the second position, the airflow can not only be discharged through the upper air outlet 2003 and the lower air outlet 2004, but also be dispersed and discharged through the first air dispersion hole 11 and the diverter hole 21 to reduce the wind speed, thereby realizing a multi-dimensional Coanda airflow combining surround airflow and central windless diffusion airflow, and then realizing the first windless air supply mode of the air conditioner 1000, which is beneficial to ensure the wind feeling requirements of different users.

[0090] like Figure 18 As shown, in Figure 17On the basis of the above, the first driving assembly 202 does not work, and the second driving assembly 204 drives the second connecting rod 203 to rotate upward relative to the first connecting rod 201. For example, when the distance between the air deflector assembly 10 and the housing 200 is less than or equal to 5 mm, the second driving assembly 204 stops, so that the air deflector assembly 10 is located at the upper limit position. At this time, the diverter plate 2 can be in the first position, and the guide column 22 cooperates with the first air diffusion hole 11 to close the first air diffusion hole 11. The air conditioner 1000 can achieve downward blowing, which is conducive to achieving rapid heating of the air conditioner 1000 when the air conditioner 1000 is in the heating mode.

[0091] As shown in Figure 19, Figure 17 or Figure 18 On the basis of this, the first drive component 202 does not work, and the second drive component 204 drives the second connecting rod 203 to rotate downward relative to the first connecting rod 201. For example, when the distance between the air guide plate assembly 10 and the shell 200 is less than or equal to 5 mm, the second drive component 204 stops, so that the air guide plate assembly 10 is located at the lower limit position. At this time, the diverter plate 2 can be in the first position, and the guide column 22 cooperates with the first air dispersion hole 11 to close the first air dispersion hole 11. The air conditioner 1000 can achieve upward blowing and can achieve protection against direct blowing. For example, when the air conditioner 1000 is in cooling mode, it is conducive to achieving rapid cooling of the air conditioner 1000.

[0092] like Figure 21 As shown, in Figure 17 On the basis of the first driving assembly 202, the first connecting rod 201 is driven to continue to move a certain distance toward the air outlet 2001, so that the air outlet space of the upper air outlet portion 2003 and the lower air outlet portion 2004 defined between the upper and lower ends of the air guide assembly 10 and the air outlet 2001 can be larger, which is convenient for the outflow of air. Figure 20 As shown, in Figure 21 On the basis of the first driving assembly 202 not working, the second driving assembly 204 drives the second connecting rod 203 to rotate downward, and the downward swing angle of the wind deflector assembly 10 can be greater than Figure 19 The middle is larger, so that the air guide plate assembly 10 avoids the airflow and blows the airflow out directly to achieve rapid cooling. It can be understood that at this time the diverter plate 2 can be located in the first position or the second position, thereby further increasing the air outlet mode of the air conditioner 1000.

[0093] Of course, in Figure 21 On the basis of the first driving assembly 202 not working, the second driving assembly 204 can also drive the second connecting rod 203 to rotate upward, and the upward swing angle of the wind deflector assembly 10 can be greater than Figure 18 The air guide plate assembly 10 avoids the air flow and blows the air out directly through the air outlet 2001.

[0094] In view of this, according to the air guide mechanism 100 of the embodiment of the present invention, by providing a first connecting rod 201 and a second connecting rod 203, the first connecting rod 201 is movably provided in the housing 200 along the extension direction of the air outlet channel 2002, one end of the second connecting rod 203 is rotatably connected to the end of the first connecting rod 201 close to the air outlet 2001, and the other end extends toward the air outlet 2001, the air guide plate assembly 10 is connected to the end of the second connecting rod 203 away from the first connecting rod 201, and is driven by the first driving assembly 202. By driving the first connecting rod 201 to move and the second driving assembly 204 driving the second connecting rod 203 to rotate relative to the first connecting rod 201, the rotation center of the air guide plate assembly 10 can be made variable, and the swing angle of the air guide plate assembly 10 and the position relative to the shell 200 of the air conditioner 1000 can be adjusted, with a variety of different air-guiding functions. At the same time, the position of the diverter plate 2 can be switched between the first position and the second position to change the air-guiding mode of the air guide plate assembly 10, further enriching the air supply mode of the air conditioner 1000.

[0095] Reference Figure 16 and Figure 21 As shown, the first connecting rod 201 is provided with a first rack 2011, which extends along the length of the first connecting rod 201. The first driving assembly 202 includes a first driving motor 2021 and a first gear 2022. The first driving motor 2021 is provided on the housing 200. The first gear 2022 is connected to the output shaft of the first driving motor 2021, and the first gear 2022 is meshed with the first rack 2011. When the first driving motor 2021 is activated, it drives the first gear 2022 to rotate. Through the cooperation between the first gear 2022 and the first rack 2011, the first connecting rod 201 can be driven to move, which can simplify the driving method of the first connecting rod 201 and ensure the reliability of the movement of the first connecting rod 201.

[0096] Of course, the present invention is not limited to this. The first drive component 202 can also be a screw drive mechanism 20. The first connecting rod 201 is connected to the screw and moves with the screw. The structure of the screw drive mechanism 20 is existing technology and will not be described in detail here.

[0097] like Figure 1 and Figure 7As shown, the second connecting rod 203 is provided with a slide groove 2031 extending along the length direction of the second connecting rod 203, the second driving assembly 204 includes a second driving motor 2041, a second gear 2042 and a third connecting rod 2043. Specifically, the second driving motor 2041 is provided on the housing 200, the second gear 2042 is connected to the output shaft of the second driving motor 2041, the third connecting rod 2043 is movably provided on the housing 200, and the third connecting rod 2043 is provided with a second rack 2044, the second rack 2044 extends along the length direction of the third connecting rod 2043, the second rack 2044 is engaged with the second gear 2042, and the third connecting rod 2043 is provided with a slider 2045 (refer to Figure 17 As shown), the slider 2045 is slidably disposed in the slide groove 2031.

[0098] The second drive motor 2041 can drive the second gear 2042 to rotate, and the third connecting rod 2043 can be driven to move through the cooperation between the second gear 2042 and the second rack 2044. The third connecting rod 2043 drives the second connecting rod 203 to rotate through the cooperation between the slider 2045 and the slide groove 2031 on the second connecting rod 203, thereby driving the wind guide plate assembly 10 to swing, thereby realizing wind guidance at different angles of the wind guide plate assembly 10.

[0099] In addition, when the second drive motor 2041 is not working and the first drive assembly 202 drives the first connecting rod 201 to move, the second connecting rod 203 moves with the first connecting rod 201, and the slider 2045 can slide in the sliding groove 2031, thereby ensuring the reliability of the movement of the second connecting rod 203.

[0100] In some embodiments of the present invention, reference Figure 3 and Figure 4 As shown, there are two drive mechanisms 20, and the two ends of the first air deflector 1 in the longitudinal direction are respectively connected to the second connecting rod 203. The two drive mechanisms 20 drive the two ends of the air deflector assembly 10 in the longitudinal direction, which can ensure the reliability of the movement of the air deflector assembly 10 and ensure that the air deflector assembly 10 moves more accurately to the preset position.
