[0053] The air guiding mechanism 100 according to an embodiment of the present utility model will be described below with reference to the drawings.
[0054] As Figure 6 、 Figure 7 and Figure 8 shown, the air guiding mechanism 100 according to an embodiment of the present utility model includes a first air guiding plate 1, a second air guiding plate 2, a link mechanism 3, and a driving motor 4.
[0055] Specifically, as Figure 1 and Figure 2 shown, in combination with Figure 3 and Figure 4 , the air guiding mechanism 100 is for an air conditioner 200. The air conditioner 200 may specifically be a ceiling unit. The air conditioner 200 includes a housing 7. The housing 7 has an air outlet 71. The housing 7 is used to form the overall appearance of the air conditioner 200. An air duct 72 is formed inside the housing 7, and the air outlet 71 is communicated with the air duct 72. An air inlet 73 may also be provided on the housing 7. The air inlet 73 is communicated with the air duct 72 to allow air to enter the air duct 72 through the air inlet 73.
[0056] As Figure 3In the illustrated example, a heat exchanger 8, a cross-flow impeller 9, etc. are also provided inside the housing 7. In the air flow direction in the air duct 72, the heat exchanger 8 is upstream of the cross-flow impeller 9. The heat exchanger 8 is used for heat exchange with the air flow passing through its surface, and the cross-flow impeller 9 is used to drive the air flow to flow from the air inlet 73 to the air outlet 71.
[0057] During the specific operation of the air conditioner 200, driven by the cross-flow impeller 9, the outside air will enter the housing 7 from the air inlet 73. After the heat exchange effect of the heat exchanger 8, the heat-exchanged air will flow out of the air conditioner 200 from the air outlet 71 under the guiding action of the first air deflector 1 and the second air deflector 2, so as to ensure the refrigeration, heating and air supply functions of the air conditioner 200.
[0058] Among them, the first air deflector 1 is rotatably arranged at the air outlet 71 for opening or closing the air outlet 71. The second air deflector 2 is rotatably arranged at the air outlet 71. When the first air deflector 1 closes the air outlet 71, the second air deflector 2 is located inside the first air deflector 1.
[0059] The first air deflector 1 can close the air outlet 71 by rotation and guide the air flow in the width direction of the air outlet 71 to blow out at different air outlet angles, so as to realize different air supply states of the air conditioner 200. The width of the second air deflector 2 is smaller than that of the first air deflector 1. The second air deflector 2 can change the air guiding direction by rotation, so that the air flow flows to the air outlet 71 and the first air deflector 1 at different angles. The second air deflector 2 can cooperate with the first air deflector 1 to better realize the function and effect of the air conditioner 200 blowing out at different angles. With the mutual cooperation of the first air deflector 1 and the second air deflector 2, a better air guiding effect can be achieved to realize different air supply states of the air conditioner 200, improve the richness of the air outlet effect of the air conditioner 200, meet the diversified air supply needs of users, and thus improve the comfort and experience of users.
[0060] Furthermore, the link mechanism 3 is rotatably connected to the first air deflector 1, and the driving motor 4 is arranged on the housing 7. The driving motor 4 is used to drive the link mechanism 3 and the second air deflector 2 to rotate simultaneously.
[0061] It can be understood that the output shaft of the driving motor 4 can provide a torque force to drive the link mechanism 3 and the second air deflector 2 to rotate, and the link mechanism 3 can realize transmission and drive the first air deflector 1 to rotate. Thus, the driving motor 4 can provide power for the rotation of the first air deflector 1 and the second air deflector 2 simultaneously to ensure the performance of the air guiding mechanism 100 and realize different air supply states of the air conditioner 200. There is no need to separately set driving motors 4 for the first air deflector 1 and the second air deflector 2, which can effectively reduce the number of driving motors 4 and reduce costs. At the same time, it can save the occupied space of the driving motors 4, and thus is beneficial to reducing the volume of the air conditioner 200.
[0062] According to the air guiding mechanism 100 of the embodiment of the present utility model, by providing a rotatable first air guiding plate 1 and a second air guiding plate 2 at the air outlet 71, the functions and effects of the air conditioner 200 blowing air at different angles can be realized, so as to realize different air supply states of the air conditioner 200, meet the diverse needs of users, and further improve the comfort and experience of users. At the same time, by providing a link mechanism 3 rotatably connected to the first air guiding plate 1 and a driving motor 4 for simultaneously driving the link mechanism 3 and the second air guiding plate 2 to rotate, the same driving motor 4 can simultaneously provide power for the rotation of the first air guiding plate 1 and the second air guiding plate 2, which can effectively reduce the number of driving motors 4 and reduce costs, and at the same time can save the occupied space of the driving motor 4, and further is beneficial to reducing the volume of the air conditioner 200.
[0063] In some embodiments, as Figure 1 and Figure 2 shown, the air outlet 71 is strip-shaped and extends along the horizontal direction. The strip-shaped air outlet 71 can increase the air supply volume and the air supply range. The first air guiding plate 1 and the second air guiding plate 2 extend along the horizontal direction and are strip-shaped to ensure the air guiding effect. The first air guiding plate 1 is adapted to the air outlet 71, which is convenient for the first air guiding plate 1 to open or close the air outlet 71. At the same time, the rotation axes between the first air guiding plate 1 and the housing 7 and between the second air guiding plate 2 and the housing 7 also extend along the horizontal direction, which is convenient for the first air guiding plate 1 and the second air guiding plate 2 to guide air in the up and down directions at the air outlet 71.
[0064] In some embodiments of the present utility model, as Figure 6 , Figure 7 and Figure 8 shown, the air guiding mechanism 100 further includes a transmission mechanism 5. The transmission mechanism 5 includes a first gear 51 and a second gear 52 that mesh with each other. The first gear shaft 511 of the first gear 51 is connected to the link mechanism 3, the second gear shaft 521 of the second gear 52 is connected to the second air guiding plate 2, and the output shaft of the driving motor 4 is connected to one of the first gear 51 and the second gear 52.
[0065] It can be understood that, as Figure 7 and Figure 8In the illustrated example, the output shaft of the drive motor 4 is connected to the first gear 51. The drive motor 4 outputs a torque force through the output shaft to provide power for the rotation of the first gear 51. The first gear shaft 511 can drive the link mechanism 3 to rotate, thereby realizing the rotation of the first air deflector 1. At the same time, the first gear 51 and the second gear 52 are meshed with each other. The first gear 51 can drive the second gear 52 to rotate, so that the second gear shaft 521 can drive the second air deflector 2 to rotate. Thus, the drive motor 4 drives the first air deflector 1 and the second air deflector 2 to rotate simultaneously, thereby ensuring the air guiding function of the air guiding mechanism 100 and realizing different air supply states of the air conditioner 200. The meshing of the transmission mechanism 5 is stable and accurate, which is beneficial to increasing the transmitted torque force and improving the stability and accuracy of the transmission, thereby reducing the pressure of the output torque force of the drive motor 4 and effectively improving the operating stability of the air guiding mechanism 100.
[0066] The following is an example to illustrate the transmission connection structure of the transmission mechanism 5 with the drive motor 4, the link mechanism 3, and the second air deflector 2: The first gear 51 may be provided with a motor shaft hole 512, so that the drive motor 4 can complete the connection with the first gear 51 through the cooperation of the output shaft and the motor shaft hole 512, thereby providing power for the rotation of the first gear 51. The link mechanism 3 may be provided with a first shaft hole 321 that cooperates with the first gear shaft 511. The transmission connection between the first gear 51 and the link mechanism 3 can be realized through the cooperation of the first gear shaft 511 and the first shaft hole 321. Both ends of the second air deflector 2 in the length direction are provided with second rotating shafts 21, and the second rotating shafts 21 are provided with second shaft holes 211 that cooperate with the second gear shafts 521. The transmission connection between the second gear 52 and the second air deflector 2 can be realized through the cooperation of the second gear shafts 521 and the second shaft holes 211.
[0067] Among them, the transmission mechanism 5 is further provided with a cover body 53. The first gear 51 and the second gear 52 are rotatably arranged in the cover body 53. The cover body 53 can protect the first gear 51 and the second gear 52, thereby ensuring the transmission stability and reliability of the transmission mechanism 5. The cover body 53 is divided into a first gear cover 531 and a second gear cover 532, which is convenient for assembly and disassembly.
[0068] In some embodiments of the present invention, such as Figure 6 、 Figure 7 and Figure 8As shown, the rotational speed of the first gear 51 is greater than that of the second gear 52, that is, the number of teeth of the first gear 51 is less than that of the second gear 52. Since the range that the first air deflector 1 needs to rotate is greater than the range that the second air deflector 2 needs to rotate, and the rotational speed of the first gear 51 is greater than that of the second gear 52, the rotational speed of the first air deflector 1 can be greater than that of the second air deflector 2. Thus, the first air deflector 1 and the second air deflector 2 can cooperate better with each other and achieve different air supply states of the air conditioner 200 under the drive of the same driving motor 4.
[0069] Among them, the transmission ratio range of the first gear 51 and the second gear 52 is 1:1 - 1:4, that is, the rotational speed ratio of the first gear 51 to the second gear 52 is 1:1 - 4:1. Thus, the ratio of the rotational speed of the first air deflector 1 to that of the second air deflector 2 is within an appropriate range, which can better achieve the cooperation with each other, thereby ensuring the realization of different air supply states of the air conditioner 200. The optimal value of the transmission ratio of the first gear 51 and the second gear 52 is 1:2. Of course, the transmission ratio of the first gear 51 and the second gear 52 can be adjusted according to the specific implementation situation, and the present application does not make specific limitations on this.
[0070] In some embodiments of the present utility model, as Figure 6 、 Figure 7 and Figure 8 shown, the two ends in the width direction of the first air deflector 1 are respectively the first end 11 and the second end 12. The link mechanism 3 is arranged close to the first end 11, which is beneficial to realizing the transmission cooperation between the link mechanism 3 and the first air deflector 1. Among them, the second end 12 of the first air deflector 1 is closer to the front of the air conditioner 200 as Figure 2 shown. When the link mechanism 3 rotates, it can generate a driving force on the first end 11 of the first air deflector 1 and drive the second end 12 of the first air deflector 1 to move to the outside of the air outlet 71 first, which is beneficial to improving the air guiding effect of the first air deflector 1 and the air outlet effect of the air outlet 71, and the structural design is reasonable.
[0071] In some embodiments of the present utility model, as Figures 3 - 8 shown, the link mechanism 3 includes a first rod 31 and a second rod 32. One end of the first rod 31 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air deflector 1 and is spaced from both the first end 11 and the second end 12. One end of the second rod 32 is connected to the driving motor 4, and the other end is rotatably connected to the first end 11 of the first air deflector 1.
[0072] It can be understood that the housing 7, the first rod 31, the second rod 32, and the first air deflector 1 can form a four-bar linkage mechanism. The first air deflector 1 is a driven component in the four-bar linkage mechanism. The driving motor 4 can provide a torque force to drive the second rod 32 to rotate. The connection point of the first rod 31 rotatably connected to the housing 7 can serve as a fulcrum. That is, the second rod 32 is the driving rod, and the first rod 31 is the driven rod. The second rod 32 can drive the first rod 31 to rotate. Through the rotation of the first rod 31 and the second rod 32, the motion can be transmitted to the first air deflector 1, so that the motion of the first air deflector 1 is no longer a simple linear or circular motion, but flips along a predetermined trajectory to complete the action of opening or closing the air outlet 71, thereby realizing different air supply states of the air conditioner 200.
[0073] The design of the above four-bar linkage mechanism is simple and low-cost, and can make the motion trajectory of the first air deflector 1 more precisely controllable. At the same time, the first rod 31 and the second rod 32 can disperse the stress and impact during the motion process, making the first air deflector 1 more stable during the process of opening or closing the air outlet 71, thereby reducing vibration and noise and enhancing the reliability and stability of the air deflector mechanism 100.
[0074] In some embodiments of the present invention, as Figure 3 , Figure 4 and Figure 5 shown, along the width direction of the first air deflector 1, the second air deflector 2 is entirely located on the side of the first air deflector 1 close to the first end 11, which is beneficial for the second air deflector 2 to cooperate with the first air deflector 1 to guide the air. Among them, the second end 12 of the first air deflector 1 is closer to the front of the air conditioner 200 as Figure 2 shown, that is, the second air deflector 2 is located on the side of the first air deflector 1 close to the rear of the air conditioner 200. Thus, at least part of the air flow in the air duct 72 can first flow through the second air deflector 2 and then flow to the first air deflector 1 and the air outlet 71 under the guidance of the second air deflector 2, which is beneficial for the cooperation between the second air deflector 2 and the first air deflector 1, thereby realizing different air supply states of the air conditioner 200.
[0075] In some embodiments of the present invention, as Figure 3 shown, when the first air deflector 1 closes the air outlet 71, in the direction from the inside to the outside of the air outlet 71, both the first rod 31 and the second rod 32 are inclined towards the first end 11. This is more convenient for the transmission of the four-bar linkage mechanism formed by the housing 7, the first rod 31, the second rod 32, and the first air deflector 1, ensuring that the first air deflector 1 can be flipped and moved under the drive of the first rod 31 and the second rod 32 to ensure the air guiding performance of the first air deflector 1 and realize the air supply function of the air conditioner 200.
[0076] Among them, when the first air guide plate 1 closes the air outlet 71, the second rod 32 and the rotation axis of the drive motor 4, and the rotation axis of the second rod 32 and the first air guide plate 1 are respectively located on the side of the rotation axis of the first rod 31 and the shell 7, and the rotation axis of the first rod 31 and the first air guide plate 1 along the width direction of the air outlet 71 close to the first end 11.
[0077] In some embodiments of the present invention, Figure 3 As shown, the rotation axis of the first rod 31 and the housing 7 is located at one side of the width direction of the air outlet 71, and the rotation axis of the second rod 32 and the drive motor 4 are spaced from both ends of the width direction of the air outlet 71. This facilitates the arrangement of components such as the drive motor 4 at the end of the second rod 32 away from the first air guide plate 1, and the spatial arrangement is reasonable. At the same time, it can avoid collision or interference between the first rod 31 and the second rod 32 during the rotation process, ensure the transmission of the four-bar linkage, and further ensure the performance of the air guide mechanism 100 and realize the air supply function of the air conditioner 200.
[0078] In some embodiments of the present invention, Figures 3 - 8 As shown, the first rod 31 is a straight rod, which is easy to process and produce, and can improve production efficiency and reduce production costs.
[0079] In some embodiments of the present invention, Figures 3 - 8 As shown, the second rod 32 is an arc-shaped rod, and when the first air guide plate 1 closes the air outlet 71, the second rod 32 protrudes toward the first rod 31. The structural strength of the second rod 32 can be enhanced to ensure the stability and reliability of the connecting rod mechanism 3. In particular, when the first air guide plate 1 closes the air outlet 71, a concave avoidance groove 322 is formed on the side of the second rod 32 away from the first rod 31, which can effectively avoid the first end 11 of the first air guide plate 1, so that the four-link transmission range is larger in a limited space, thereby increasing the flip angle range of the first air guide plate 1 and improving the wind guide effect.
[0080] For example, Figure 5 In the example shown, when the air conditioner 200 delivers hot air, the first air guide plate 1 rotates driven by the connecting rod mechanism 3, so that the first end 11 is located obliquely above the second end 12, and the first air guide plate 1 is slightly tilted toward the front of the air conditioner 200 in the top-to-bottom direction. At this time, the first end 11 of the first air guide plate 1 can extend into the recessed avoidance groove 322 formed by the second rod 32. The recessed avoidance groove 322 of the second rod 32 can make the first air guide plate 1 tilt downward at a larger angle, that is, closer to a vertical state, which can enhance the effect of the first air guide plate 1 in guiding the hot air flow downward, and the temperature rise efficiency is improved, thereby helping to improve the heating effect of the air conditioner 200.
[0081] In some embodiments of the present invention, Figure 3As shown, when the first air deflector 1 closes the air outlet 71, the rotation axis of the second rod 32 and the first air deflector 1 is located on the side of the rotation axis of the second rod 32 and the housing 7 that is away from the first rod 31. This facilitates the rotation of the second rod 32 to drive the first air deflector 1 to move towards the outside of the air outlet 71. The structural design is reasonable, which is conducive to the transmission between the first air deflector 1 and the link mechanism 3, thereby realizing the closing or opening of the air outlet 71 and realizing different air supply functions of the air conditioner 200.
[0082] As Figure 3 and Figure 4 shown in the example, the rotation axis of the first rod 31 and the housing 7 is located on the side of the second end 12 in the width direction of the air outlet 71, and the rotation axis of the end of the second rod 32 away from the first air deflector 1 is spaced from both ends in the width direction of the air outlet 71. When the first air deflector 1 closes the air outlet 71, the rotation axis of the second rod 32 and the first air deflector 1 is located on the side of the first end 11 in the width direction of the air outlet 71, and the rotation axis of the first rod 31 and the first air deflector 1 is spaced from both ends in the width direction of the air outlet 71. When the air conditioner 200 blows air, the rotation of the first rod 31 and the second rod 32 can drive the first air deflector 1 to flip downward, the first end 11 of the first air deflector 1 moves upward, and the second end 12 of the first air deflector 1 moves downward, thereby opening the air outlet 71 to realize the air supply function of the air conditioner 200.
[0083] In some embodiments of the present invention, as Figure 6 , Figure 7 and Figure 8 shown, there are multiple first rods 31 spaced apart along the length direction of the first air deflector 1, and there are multiple second rods 32 spaced apart along the length direction of the first air deflector 1. Thus, in the length direction of the first air deflector 1, the housing 7, the first rod 31, the second rod 32, and the first air deflector 1 can form multiple four-bar linkages, so that during the process of the first rod 31 and the second rod 32 rotating to drive the first air deflector 1 to rotate, the force on the first air deflector 1 can be dispersed and more uniform, which helps to improve the reliability and stability of the air guiding mechanism 100.
[0084] In some embodiments of the present invention, as Figure 3 , Figure 4 and Figure 5 shown, the inner surface of the first air deflector 1 has a first inclined surface 13, the first inclined surface 13 is located at the first end 11 and extends along the length direction of the first air deflector 1, and in the direction from the first end 11 to the second end 12, the first inclined surface 13 is inclined towards the direction away from the outer surface of the first air deflector 1.
[0085] Therefore, when the first air guide plate 1 opens the air outlet 71 to guide the air, the first end 11 of the first air guide plate 1 moves to the inside of the air outlet 71, and at the same time, the second end 12 of the first air guide plate 1 rotates to the outside of the air outlet 71. Since the first inclined surface 13 is inclined in the direction from the first end 11 to the second end 12 in the direction away from the outer surface of the first air guide plate 1, when the airflow flows from the first end 11 to the second end 12 along the width direction of the first air guide plate 1, the first inclined surface 13 can produce an upward supporting effect on the airflow, and the airflow can thus flow obliquely upward, thereby increasing the flow distance of the airflow and enhancing the air supply distance and long-distance air supply effect of the air conditioner 200.
[0086] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the thickness of one end of the first air guide plate 1 connected to the connecting rod mechanism 3 is h1, and satisfies: h1>0.5mm. If h1≤0.5mm, the thickness of the first end 11 of the first air guide plate 1 is too thin, which affects the connection strength between the first air guide plate 1 and the connecting rod mechanism 3. Therefore, h1>0.5mm can ensure the structural strength of the first end 11 of the first air guide plate 1, thereby ensuring the connection stability between the first air guide plate 1 and the connecting rod mechanism 3. Of course, h1 cannot be too large, which will generate resistance to the airflow at the air outlet 71, which is not conducive to the air guiding of the first air guide plate 1 and is prone to generate noise.
[0087] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 5 As shown, the inner surface of the first air guide plate 1 has a second inclined surface 14, which is located at the second end 12 and extends along the length direction of the first air guide plate 1. In the direction from the first end 11 to the second end 12, the second inclined surface 14 is inclined toward the direction close to the outer surface of the first air guide plate 1.
[0088] Thus, in the width direction of the first air guide plate 1, the thickness in the middle of the first air guide plate 1 is greater than the thickness at both ends of the first air guide plate 1, and part of the airflow flowing through the first inclined surface 13 can flow obliquely downward along the second inclined surface 14, which can increase the direction of the airflow flow and enhance the air guiding effect of the first air guide plate 1, thereby increasing the air supply range and air supply effect. In addition, reducing the thickness of the second end 12 of the first air guide plate 1 can also effectively reduce the weight of the air outlet end of the first air guide plate 1, which is conducive to enhancing the stability of the rotation of the first air guide plate 1.
[0089] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the thickness of one end of the first air deflector 1 in the width direction, which is away from the link mechanism 3, is h3, and it satisfies: h3 > 1 mm. If h3 ≤ 1 mm, the thickness of the first end 11 of the first air deflector 1 is too thin, which affects the structural strength of the air outlet end of the first air deflector 1, thereby affecting the stability of its supporting the air flow. Thus, making h3 > 1 mm can ensure the structural strength of the second end 12 of the first air deflector 1, thereby ensuring the stability of the air diversion at the air outlet end of the first air deflector 1. Of course, h3 cannot be too large, as it will increase the weight of the air outlet end of the first air deflector 1, which is not conducive to the stability of the rotation of the first air deflector 1.
[0090] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the maximum thickness of the first air deflector 1 is h2, and it satisfies: 3 mm < h2 < 10 mm. If h2 ≤ 3 mm, the inclination angle of the first inclined surface 13 is too small, which is not conducive to the effect of the first inclined surface 13 supporting the air flow and guiding it obliquely upward. If h2 ≥ 10 mm, the maximum thickness of the first air deflector 1 is too thick, which will increase the weight of the first air deflector 1, which is not conducive to the stability of the rotation of the first air deflector 1. Thus, making 3 mm < h2 < 10 mm can ensure the effect of the first air deflector 1 supporting the air flow and guiding it obliquely upward, thereby enhancing the air supply distance and the long-distance air supply effect of the air conditioner 200, and can also avoid the overweight of the first air deflector 1, thereby ensuring the stability of the rotation of the first air deflector 1.
[0091] In some embodiments, such as Figure 1 and Figure 3 As shown, the air conditioner 200 has a closed state. When the user does not need to use the air conditioner 200, the air conditioner 200 stops blowing air, and the first air deflector 1 can be rotated to the position of closing the air outlet 71 and the link mechanism 3 is located inside the first air deflector 1. At this time, the first air deflector 1 and the housing 7 form the complete appearance of the air conditioner 200, thereby improving the aesthetics of the air conditioner 200. At the same time, it can also play a role in dust prevention to ensure the cleanliness inside the air conditioner 200. The air guiding mechanism 100 can ensure the basic functions of the air conditioner 200 and improve the practicability of the air conditioner 200.
[0092] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the air outlet 71 of the air conditioner 200 is located on the lower surface of the housing 7. The air conditioner 200 has an air outlet state. In the air outlet state, the second end 12 is flipped to the outside of the air outlet 71, and the second air deflector 2 is located on one side of the first end 11 of the first air deflector 1 along the width direction of the air outlet 71.
[0093] It can be understood that the air inlet end of the first air deflector 1 is spaced from both ends in the width direction of the air outlet 71. The air outlet end of the first air deflector 1 is obliquely below the air inlet end and the inclination angle of the first air deflector 1 is small. The inner surface of the first air deflector 1 can guide at least part of the air flow flowing out from the air outlet 71 to flow in the horizontal direction or the obliquely upward direction, which can increase the distance of the air flow, so as to realize air supply over a longer distance, accelerate the cooling speed at a distant position of the air conditioner 200, improve the indoor cooling efficiency and enhance the comfort of users located far away from the air conditioner 200.
[0094] Meanwhile, there is a duct 72 communicated with the air outlet 71 in the housing 7. The air outlet end of the second air deflector 2 is obliquely below the air inlet end of the second air deflector 2, and the air outlet end of the second air deflector 2 is close to or flush with the air inlet end of the first air deflector 1. Thus, the second air deflector 2 is more convenient for cooperating with the first air deflector 1 to deflect air. The first air deflector 1 and the second air deflector 2 can be connected in series to become an extension of the duct 72, guiding at least part of the air flow in the duct 72 to flow in a generally horizontal direction above the first air deflector 1, and then the first air deflector 1 guides the air flow to flow in a direction close to the horizontal direction, which can further increase the distance of the air flow, thereby enhancing the air supply effect over a longer distance, and further improving the indoor cooling efficiency and enhancing the comfort of users located far away from the air conditioner 200.
[0095] Further, in the air outlet direction of the air flow, the air flow can be guided by the second air deflector 2 in the duct 72 to form two split air flows. The one above the second air deflector 2 is the first split air flow 61, and the one below the second air deflector 2 is the second split air flow 62. Under the guiding action of the second air deflector 2 and the first air deflector 1, the first split air flow 61 can be divided into a first sub-air flow 611 and a second sub-air flow 612. Among them, the first sub-air flow 611 is guided above the first air deflector 1, the second split air flow 62 flows below the first air deflector 1, and the second sub-air flow 612 is guided to flow between the first air deflector 1 and the second split air flow 62. In Figure 4 the illustrated example, multiple arrows respectively show the schematic of the flow directions of the first split air flow 61, the second split air flow 62, the first sub-air flow 611 and the second sub-air flow 612.
[0096] Thus, the second sub-airflow 62 is located below the second sub-airflow 612, and can generate a force to support the second sub-airflow 612, such that the second sub-airflow 612 flows below the second air deflector 2 and adheres to the surface of the second air deflector 2. After the airflows through the first air deflector 1, the second sub-airflow 612 and the second sub-airflow 62 below can generate a force to support the first sub-airflow 611, such that the first sub-airflow 611 can flow a longer distance, thereby achieving a better long-distance air supply effect, further accelerating the cooling speed at a distant position of the air conditioner 200, improving the indoor cooling efficiency and enhancing the comfort of users located far away from the air conditioner 200.
[0097] In addition, the second sub-airflow 62 generates a force to support the second sub-airflow 612, and the second sub-airflow 612 can flow along the lower surface of the second air deflector 2, such that cold airflows adhere to the walls on both the upper and lower surfaces of the first air deflector 1, effectively preventing dew condensation on both sides in the thickness direction of the first air deflector 1 during the air guiding process due to excessive temperature difference.
[0098] In some embodiments, as Figure 5 shown, the air conditioner 200 has a heating state. The first end 11 of the first air deflector 1 is located obliquely above the second end 12. In the direction from top to bottom, the first air deflector 1 is slightly inclined forward towards the air conditioner 200, and the second air deflector 2 and the first air deflector 1 are arranged substantially parallel. The first air deflector 1 and the second air deflector 2 can guide the hot airflows flowing out from the air outlet 71 substantially vertically downward, causing the hot airflows to blow downward, which is conducive to the expansion and rise of hot air and the fall of cold air, accelerating the air circulation in the room, making the indoor temperature rise faster, and improving the heating effect of the air conditioner 200.
[0099] In some embodiments of the present invention, as Figure 3 、 Figure 4 and Figure 5 shown, the second air deflector 2 is an arc-shaped plate. When the first air deflector 1 closes the air outlet 71, the second air deflector 2 protrudes towards the outside of the air outlet 71. When the air conditioner 200 supplies air and the second air deflector 2 guides the air, the surface of the arc helps to concentrate the airflows and reduce the wind resistance, enabling the air supply distance to be farther, enhancing the air supply ability of the air conditioner, and thus improving the air circulation efficiency. At the same time, the concave design enables the airflows to flow more smoothly, reducing the retention of airflows on the second air deflector 2, reducing the wind resistance and lowering the noise, which helps to improve the use comfort. In addition, the arc-shaped second air deflector 2 can also effectively avoid the first air deflector 1 when the air guiding mechanism 100 guides the air, thereby ensuring the operation of the air guiding mechanism 100.
[0100] In some embodiments of the present invention, as Figure 3 and Figure 4As shown, the radius of the second air deflector 2 is R, and it satisfies: 5 mm < R < 20 mm; if R ≥ 20 mm, the radius of the second air deflector 2 is too large, the arc formed by the second air deflector 2 is too small, and the effect of the second air deflector 2 in supporting the air flow becomes poor, which is not conducive to the air guiding effect of the second air deflector 2; if R ≤ 5 mm, the radius of the second air deflector 2 is too small, the arc formed by the second air deflector 2 is too large, which is not conducive to the smooth flow of the air flow around the second air deflector 2, and is not conducive to the cooperation between the second air deflector 2 and the first air deflector 1 to split the first sub-air flow 61 into the first sub-air flow 611 and the second sub-air flow 612. Therefore, making 5 mm < R < 20 mm can better ensure the air guiding effect of the second air deflector 2, and further improve the air guiding effect of the air guiding mechanism 100.
[0101] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the dimension of the connection line between the two ends in the width direction of the first air deflector 1 is L1, and it satisfies: 10 mm < L1 < 25 mm. If L1 ≥ 25 mm, the width of the second air deflector 2 is too large, and it is easy to collide with the first air deflector 1; if L1 ≤ 10 mm, the width of the second air deflector 2 is too small, resulting in a reduction in the air guiding ability of the second air deflector 2. Therefore, making 10 mm < L1 < 25 mm can not only better ensure the air guiding effect of the second air deflector 2, but also prevent interference between the first air deflector 1 and the second air deflector 2, and further improve the air guiding effect of the air guiding mechanism 100.
[0102] In some embodiments of the present invention, such as Figure 3 、 Figure 4 and Figure 5 As shown, the first air deflector 1 is a single-layer solid plate-like structure, which has a simple structure and is convenient for processing and maintenance, helping to reduce production costs.
[0103] In some embodiments of the present invention, the first air deflector 1 includes a first plate and a second plate stacked on top of each other. The two ends in the width direction of the first plate and the second plate are connected, and a cavity is defined in the middle. Dividing the first air deflector 1 into the first plate and the second plate is convenient for separately processing the first plate and the second plate into arc surfaces, and then assembling and connecting them, so that the first air deflector 1 forms a double-sided concave arc surface structure in the thickness direction, which is convenient for processing and production. At the same time, the cavity defined between the first plate and the second plate can effectively prevent the condensation phenomenon from occurring on both sides in the thickness direction of the first air deflector 1 due to too large a temperature difference during the air guiding process. Structures such as sponges can also be provided in the cavity to further enhance the anti-condensation effect.
[0104] The following describes the air conditioner 200 according to the embodiments of the present invention.
[0105] The air conditioner 200 according to an embodiment of the present utility model includes: a housing 7 and the above-mentioned air guiding mechanism 100.
[0106] Specifically, as Figure 1 and Figure 2 shown, in combination with Figure 3 and Figure 4 , the housing 7 has an air outlet 71; the first air guiding plate 1 is rotatably arranged at the air outlet 71 for opening or closing the air outlet 71, and the second air guiding plate 2 is rotatably arranged at the air outlet 71. When the first air guiding plate 1 closes the air outlet 71, the second air guiding plate 2 is located inside the first air guiding plate 1.
[0107] The air conditioner 200 according to an embodiment of the present utility model can achieve the functions and effects of the air conditioner 200 blowing air at different angles by arranging the rotatable first air guiding plate 1 and second air guiding plate 2 at the air outlet 71, thereby realizing different air supply states of the air conditioner 200 to meet the diverse needs of users, and further improving the comfort and experience of users. At the same time, by arranging the link mechanism 3 rotatably connected to the first air guiding plate 1 and the driving motor 4 for simultaneously driving the link mechanism 3 and the second air guiding plate 2 to rotate, the same driving motor 4 can provide power for the rotation of both the first air guiding plate 1 and the second air guiding plate 2, which can effectively reduce the number of driving motors 4 and lower the cost. At the same time, the occupied space of the driving motor 4 can be saved, which is beneficial to reducing the volume of the air conditioner 200.
[0108] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the air conditioner 200 is a ceiling-mounted unit, and the air outlet 71 is located on the lower surface of the housing 7. The ceiling-mounted unit can avoid occupying the user's activity space, and the air outlet 71 located on the lower surface of the housing 7 can better supply air to the room in all directions, which can ensure the air supply effect of the air conditioner 200.
