Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air guide plate assembly, an air guide device, and an air conditioner. Background Technology

[0002] Some single-flow cabinet air conditioners in related technologies often use a single-layer micro-perforated air guide plate to achieve a windless function. However, due to structural limitations, the micro-perforated air guide plate allows cold air to enter and exit axially (the thickness direction of the air guide plate) through the micro-holes, resulting in poor diffusion and flow of cold air radially (the plane direction of the air guide plate). This leads to a poor user experience as the cold air cannot be effectively dispersed. Furthermore, if the airflow is increased, the blowing effect is still noticeable in cooling mode, causing user discomfort. Adding a swivel blade air guide plate with rotating blades to the inside of the micro-perforated air guide plate requires an additional drive mechanism, resulting in a complex mechanism, higher cost, and difficulty in guaranteeing operational reliability.

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0048] Hereinafter, with reference to the accompanying drawings, a wind deflector assembly 10 according to a first aspect of the present invention will be described.

[0049] like Figure 1 and Figure 2 As shown, the air guide plate assembly 10 may include a first air guide plate 1, which may include a plate body 11 and a stationary blade 12. The plate body 11 has a pivot axis 111 extending along the length direction F1 of the plate body 11. That is, the plate body 11 can rotate about the pivot axis 111. The pivot axis 111 extends along the length direction F1 of the plate body 11, but the pivot axis 111 may pass through the plate body 11 or may not pass through the plate body 11.

[0050] Combination Figures 2-4 The plate 11 has a first ventilation opening 112 extending along the length direction F1 of the plate 11. The first ventilation opening 112 is provided with a plurality of stationary blades 12 arranged at intervals along the length direction F1 of the first ventilation opening 112. The root and tip of each stationary blade 12 in the first ventilation opening 112 extend to the two sides of the width of the first ventilation opening 112 respectively. Moreover, at least two stationary blades 12 in the first ventilation opening 112 have different installation angles. That is to say, the installation angles of all stationary blades 12 in the same first ventilation opening 112 are not consistent.

[0051] It is understandable that the first vent 112 penetrates both sides of the thickness of the plate 11, allowing airflow to pass through the first vent 112 from one side of the thickness of the plate 11 to the other side. The angle between the chord line at the blade root of the stationary blade 12 and the pivot axis 111 is the installation angle of the stationary blade 12. For example... Figure 4 The mounting angles of the first stationary blade 121 and the second stationary blade 122 shown are different.

[0052] Therefore, the airflow passing through the first vent 112 can be guided by stationary blades 12 with different installation angles. The airflow guided by the stationary blades 12 with different installation angles has different outlet directions. The airflows with different directions can collide and consume axial wind speed to a certain extent, reducing the blowing sensation index and improving the comfort experience. For example, when the airflow passing through the first vent 112 is cold air, it can improve the problem of cold air blowing directly on the user. Furthermore, since the blowing sensation can be reduced, the wind speed of the airflow passing through the first vent 112 can be appropriately increased, thereby improving the cooling capacity and better balancing the blowing sensation and cooling effect. Of course, the present invention is not limited to this; the airflow passing through the first vent 112 can also be hot air, which is not limited here.

[0053] Furthermore, it is understood that the stationary blade 12 is not rotatable relative to the plate 11. It can be integrally formed with the plate 11, or it can be fixed to the plate 11 through subsequent processes such as assembly; there are no restrictions here. By setting the stationary blade 12, compared with the solution of setting a rotatable blade, the cost can be further reduced, eliminating the mechanism for driving the blade to rotate, thereby reducing costs and improving the reliability of the air dispersion effect.

[0054] In some embodiments of the present invention, such as Figures 5-7 As shown, the multiple stationary blades 12 within the first vent 112 include a first stationary blade 121 and a second stationary blade 122. That is, at least one stationary blade 12 within the first vent 112 is a first stationary blade 121, and at least one stationary blade 12 within the first vent 112 is a second stationary blade 122. The installation angle X1 of the first stationary blade 121 is an acute angle, and the installation angle X2 of the second stationary blade 122 is an obtuse angle. Therefore, the airflow guided out by the first stationary blade 121 and the airflow guided out by the second stationary blade 122 have a significantly different angle, which allows for better collision and dissipation of axial wind speed, better reduction of the draft index, and improved comfort. This, in turn, can significantly increase the wind speed of the airflow passing through the first vent 112, thereby improving cooling capacity and better balancing draft feel and cooling effect.

[0055] Furthermore, such as Figure 4 and Figure 7As shown, the first vent 112 is provided with multiple first stationary blades 121 and multiple second stationary blades 122. N consecutive first stationary blades 121 and M consecutive second stationary blades 122 are alternately arranged, where N and M are both integers greater than or equal to 1. For example, along the length F1 of the first vent 112, N consecutive first stationary blades 121 can be arranged, followed by M consecutive second stationary blades 122, and so on. Therefore, the airflow guided by the first stationary blades 121 and the airflow guided by the second stationary blades 122 are relatively closer, allowing for better collision and axial wind speed reduction, thus better reducing the draft index and improving comfort. This further increases the wind speed of the airflow passing through the first vent 112, thereby improving cooling capacity and better balancing draft feel and cooling effect. It should be noted that N and M can be the same or different. For example, N can be 1, 2, 3, 4, etc., and M can be 1, 2, 3, 4, etc.

[0056] For example, in some specific examples, such as Figure 4 and Figure 7 As shown, multiple first stationary blades 121 and multiple second stationary blades 122 are arranged alternately in pairs, meaning that both N and M are 2. For example, along the length F1 of the first vent 112, two first stationary blades 121 can be arranged consecutively, followed by two second stationary blades 122, then two more first stationary blades 121, then two more second stationary blades 122, and so on. Thus, two second stationary blades 122 and two first stationary blades 121 can form one air guide unit 101. One air guide unit 101 can generate three airflows: one airflow between two first stationary blades 121, one airflow between two second stationary blades 122, and one airflow between adjacent first stationary blades 121 and second stationary blades 122. This allows for more effective dissipation of axial wind speed and reduction of the perceived wind speed through the collision of three jets.

[0057] In some embodiments, when a plurality of first stationary blades 121 and a plurality of second stationary blades 122 are alternately arranged in pairs, such as Figure 4 and Figure 7 As shown, the installation angle X1 of the first stationary blade 121 can be 35°-60°, for example, X1 can be 35°, 40°, 45°, 50°, 55°, 60°, etc., and the installation angle X2 of the second stationary blade 122 can be 120°-140°, for example, X2 can be 120°, 125°, 130°, 135°, 140°, etc. This allows for a more effective collision of the three jets, more effectively consuming axial wind speed and reducing the perceived wind speed.

[0058] In some embodiments of the present invention, there are multiple first ventilation openings 112, which are spaced apart along the width and / or length direction F1 of the plate 11. For example, in Figure 2 In the example shown, the plate 11 has three first ventilation openings 112, namely the first air opening 112a, the second air opening 112b and the third air opening 112c. The first air opening 112a and the second air opening 112b are spaced apart along the width direction of the plate 11, and the first air opening 112a and the third air opening 112c are also spaced apart along the width direction of the plate 11. The second air opening 112b and the third air opening 112c are spaced apart along the length direction F1 of the plate 11.

[0059] Therefore, the overall dimensions of the first vent 112 on the plate 11 can be maximized, thereby improving ventilation efficiency. Furthermore, it can be adapted to the shape of the plate 11, for example, by combining... Figure 2 When the plate 11 has a notch 115, first vents 112 can be provided on both sides of the notch 115 along the length direction F1 of the plate 11, such as the second vent 112b and the third vent 112c shown in the figure, thereby improving the adaptability to the plate 11. In addition, when several first vents 112 are spaced apart along the width direction of the plate 11, and a stationary blade 12 is provided in each vent, the collision between airflows ejected in different directions can be further improved, thereby better consuming axial wind speed, better reducing the blowing sensation index, and improving the comfort experience.

[0060] Optionally, such as Figure 2 and Figure 4 As shown, the width of the plate 11 has a hub 113 extending along the length direction F1 of the plate 11 at its center. First ventilation openings 112 are provided on both sides of the hub 113, and the root of the stationary blade 12 is connected to the hub 113. That is, the hub 113 has first ventilation openings 112 on both sides of the width direction of the plate 11. The end of the stationary blade 12 connected to the hub 113 is the blade root, and the end of the stationary blade 12 away from the hub 113 (the end near the two sides of the width of the plate 11, as shown in the figure) is the blade tip. Therefore, by setting the hub 113, the stationary blade 12 can be connected using the hub 113. Furthermore, by providing first ventilation openings 112 on both sides of the hub 113, the design of the stationary blades 12 within the first ventilation openings 112 on both sides of the hub 113 allows the airflow on both sides to converge towards the direction closer to the hub 113, forming a collision. This better consumes axial wind speed, reduces the draft index, and improves comfort.

[0061] For example in Figures 3-5In the example shown, the stationary blades 12 on both sides of the width of the hub 113 can be arranged symmetrically about the centerline of the hub 113. The centerline of the hub 113 can be a line extending along the length F1 of the plate 11 and located at the center of the width of the plate 11. This facilitates manufacturing and allows the airflow on both sides of the hub 113 to better collide in the direction closer to the hub 113, thereby better dissipating axial wind speed, reducing the draft index, and improving comfort.

[0062] Optionally, such as Figure 4 and Figure 5 As shown, the hub 113 has a hollow structure, that is, the hub 113 is a non-solid structure, which can reduce wind resistance and increase ventilation. Of course, the present invention is not limited to this; in other embodiments of the present invention, the hub 113 may also be a solid structure.

[0063] In some embodiments, such as Figure 2 and Figure 5 As shown, a second vent 114 is provided on one side of the wheel hub 113 near the length end of the plate 11. The second vent 114 connects to the ends of two first vents 112 located on both sides of the width of the wheel hub 113. That is, the ends of the two first vents 112 on both sides of the wheel hub 113 near the same length end of the wheel hub 113 are connected by the second vent 114 provided at that end of the wheel hub 113. For example, in Figure 2 In the example shown, the plate 11 has an upper end and a lower end at its two ends. A second vent 114 is located on the upper side of the hub 113 near the upper end, and another second vent 114 is located on the lower side of the hub 113 near the lower end. The upper second vent 114 connects the upper end of the first vent 112a to the upper end of the second vent 112b, and the lower second vent 114 connects the lower end of the first vent 112a to the lower end of the third vent 112c. Therefore, by providing the second vent 114, the ventilation rate of the plate 11 can be further improved.

[0064] Furthermore, such as Figure 2 and Figure 5 As shown, at least one stationary blade 12 is provided inside the second vent 114, and the root and tip of each stationary blade 12 in the second vent 114 extend to the two sides of the width of the second vent 114, respectively. Therefore, since the extension direction of the second vent 114 is different from that of the first vent 112, the airflow guided by the stationary blade 12 in the second vent 114 can collide with the airflow guided by the stationary blade 12 in the first vent 112, thereby better consuming axial wind speed, better reducing the draft index, and improving comfort.

[0065] For example, alternatively, such as Figure 2 and Figure 5 As shown, the second vent 114 is a semi-circular ring protruding towards the long end of the plate 11, for example in Figure 2 In the example shown, the two ends of the length of the plate 11 are the upper and lower ends, respectively. The second vent 114 above the hub 113 is an upwardly protruding semi-circular ring, and the second vent 114 below the hub 113 is a downwardly protruding semi-circular ring. Thus, without considering the notch 115, the first vent 112 and the second vent 114 can roughly form an oblong vent. The distance L1 between the furthest points of the second vents 114 on both sides of the length of the plate 11 along the length direction F1 of the plate 11 is more than 80% of the length L2 of the plate 11, i.e., L1 ≥ 0.8L2. This further improves the space utilization of the plate 11, increases ventilation efficiency, and allows the airflow guided by the stationary blades 12 in the second vent 114 to better collide with the airflow guided by the stationary blades 12 in the first vent 112, thereby better consuming axial wind speed, reducing the draft index, and improving comfort.

[0066] In some embodiments of the present invention, such as Figure 1 and Figure 8 As shown, the air guide plate assembly 10 may further include a second air guide plate 2. The second air guide plate 2 has the same thickness direction as the first air guide plate 1, and the second air guide plate 2 is located on the air outlet side of the first air guide plate 1. That is, the first air guide plate 1 is located on the thickness side of the second air guide plate 2, and the second air guide plate 2 is also located on the thickness side of the first air guide plate 1. The airflow from the first air guide plate 1 flows to the second air guide plate 2. The second air guide plate 2 has multiple air outlets 21, and there is a cavity between the second air guide plate 2 and the first air guide plate 1 that communicates with the air outlets 21. Thus, the airflow flowing out through the vents on the first air guide plate 1, such as the first vent 112 and the second vent 114, can first enter the cavity, effectively consuming the axial wind speed, and then be discharged through the air outlets 21 on the second air guide plate 2, thereby better reducing the blowing sensation index and improving the comfort experience.

[0067] The second air guide plate 2 is connected to the first air guide plate 1 and they both rotate around the pivot axis 111. That is, the second air guide plate 2 and the first air guide plate 1 are integrally formed or assembled together. In short, the two can rotate together around the pivot axis 111. For example, a pivot axis 22 can be set on one of the first air guide plate 1 and the second air guide plate 2, and the central axis of the pivot axis 22 is the pivot axis 111. Thus, when the first air guide plate 1 and the second air guide plate 2 are driven to rotate around the pivot axis 22, the two can rotate together around the pivot axis 111.

[0068] It should be noted that the assembly and connection method between the second air guide plate 2 and the first air guide plate 1 is not limited. For example, in some embodiments, it can be combined with... Figure 9 The edge of the second air guide plate 2 is connected to or integrally formed with a flange 3, the flange 3 surrounds the edge of the first air guide plate 1, and the flange 3 is snapped to the edge of the first air guide plate 1.

[0069] Optionally, combined Figure 9 The minimum dimension of the cavity in the thickness direction of the air guide plate assembly 10 is more than 0.25 times the thickness of the air guide plate assembly 10 at the first air guide plate 1 and the second air guide plate 2. That is, the thickness of the air guide plate assembly 10 at the first air guide plate 1 and the second air guide plate 2 is L, and the minimum dimension of the cavity in the thickness direction of the air guide plate assembly 10 is a, where a / L is greater than or equal to 0.25. For example, a is 0.25L, 0.28L, 0.3L, 0.35L, 0.4L, etc. This ensures that the airflow flowing out through the vents on the first air guide plate 1, such as the first vent 112 and the second vent 114, can effectively consume the axial wind speed when entering the cavity, and then be discharged through the air outlet 21 on the second air guide plate 2, thereby better reducing the blowing sensation index and improving the comfort experience.

[0070] It is worth noting that if the gap 'a' is too small, the airflow will not be entrained and dissipated after passing through the stationary blade 12, and will directly flow through the air outlet of the second air guide plate 2, resulting in a high outlet air velocity and a poor user experience. Furthermore, it should be noted that the specific location of the minimum dimension of the cavity in the thickness direction of the air guide plate assembly 10 needs to be determined based on the specific structural shapes of the first air guide plate 1 and the second air guide plate 2. For example, when the second air guide plate 2 has a forward-convex structure in the middle, and the first air guide plate 1 has a hub 113 that protrudes forward relative to the stationary blade 12, then the distance between the hub 113 and the middle of the second air guide plate 2 is the minimum dimension 'a'. If the first air guide plate 1 has a stationary blade 12 that protrudes forward relative to the hub 113, then the distance between the stationary blade 12 and the second air guide plate 2 is the minimum dimension 'a', which will not be elaborated further here.

[0071] Some single-flow cabinet air conditioners in related technologies often use a single-layer micro-perforated air guide plate to achieve the windless function. However, due to structural limitations, the cold air enters and exits along the axial direction (thickness direction of the air guide plate) from the micro-perforations, while the diffusion effect of the cold air along the radial direction (planar direction of the air guide plate) is poor. The cold air cannot be effectively diffused, resulting in a poor user experience. Furthermore, if the air volume is increased, the blowing effect is still obvious when the user is in cooling mode, causing discomfort. If a swirl vane air guide plate with rotatable blades is added to the inside of the micro-perforated air guide plate, an additional drive mechanism is required, resulting in a complex mechanism, high cost, and difficulty in guaranteeing operational reliability.

[0072] In order to at least solve one of the above-mentioned technical problems, this application proposes an air guide plate assembly 10. The air guide plate assembly 10 according to a specific embodiment of the present invention is described below.

[0073] The air guide plate assembly 10 includes a first air guide plate 1 and a second air guide plate 2. The first air guide plate 1 has a generally oblong vent, and the vent is provided with multiple stationary blades 12. The oblong shape refers to an approximately elliptical shape composed of a rectangle and two semicircles at both ends of the rectangle. The second air guide plate 2 has multiple air supply holes 21. The shape of the air supply holes 21 is not limited and can be polygonal, circular, etc. The two ends of the length of the second air guide plate 2 are respectively provided with pivot shafts 22. The first air guide plate 1 and the second air guide plate 2 are fixedly connected and can rotate together around the central axis of the pivot shaft 22.

[0074] A hub 113 extending along the length direction F1 of the first air guide plate 1 is provided at the center of its width. Stable blades 12 are provided on both sides of the width direction of the first air guide plate 1. There are multiple stable blades 12 on each side, which are spaced apart along the length direction F1 of the first air guide plate 1. The root of each stable blade 12 is connected to the hub 113, and the tip of the blade extends to the width side edge of the first air guide plate 1 in a direction away from the hub 113. The chord length of the stable blade 12 gradually increases from the blade root to the blade tip. For example, the chord length at the blade tip is about 5 mm, and the chord length at the blade root is about 3 mm. The size of the first vent 112 in the width direction of the first air guide plate 1 is about 8 mm-9 mm. The stable blades 12 extend from the blade root to the blade tip in an inclined direction in the width direction of the first air guide plate 1. For example, the extension length from the blade root to the blade tip, i.e., the blade height, is 12 mm. The spacing between adjacent stable blades 12 in the width direction of the first air guide plate 1 can be 6-8 mm, and the spacing between adjacent stable blades 12 in the length direction F1 of the first air guide plate 1 can be 2-6 mm. The thickness of the air guide plate assembly 10 at the first air guide plate 1 and the second air guide plate 2 is L, and the minimum dimension of the cavity in the thickness direction of the air guide plate assembly 10 is a, where a / L is greater than or equal to 0.25.

[0075] Multiple stationary blades 12 are arranged in a 2-positive-2-negative configuration along the length F1 of the first air guide plate 1, that is, two first stationary blades 121 and two second stationary blades 122 form a unit. The installation angle X1 of the first stationary blade 121 is 35°-60°, and the installation angle X2 of the second stationary blade 122 is 120°-140°. Thus, the airflow through the first air guide plate 1 can form three jets colliding and consuming axial wind speed through this unit, and then being delivered through multiple air outlets 21 of the second air guide plate 2. This can achieve double-layer wind control technology, with the colliding flow superimposed with turbulence, achieving double-layer precise wind control, reducing the wind feel index within the range of personnel activity, and improving the comfort experience.

[0076] Therefore, according to the embodiment of the present invention, the air guide plate assembly 10, by setting the first air guide plate 1 and cooperating with the second air guide plate 2, can effectively improve its air dispersion effect. For example, through flow field analysis and experimental data, after softening the wind feel, the DR value within 2.5m directly in front of the crowd's activity range can be less than 5%, increasing the air volume in the windless mode by 28%, thus improving the windless capability and increasing the windless air volume from 450m³ / h. 3 / h increased to 630m 3 / h. In short, the radial dispersion of the first air guide plate 1 and the microporous dispersion of the second air guide plate 2 reduce the blowing sensation index, achieve a windless feeling, increase the air volume in the windless mode, and improve the user's comfort.

[0077] Compared with the aforementioned related technologies, the air guide plate assembly 10 according to the embodiments of the present invention can use the first air guide plate 1 to disperse the cold air, reduce the wind speed, and prevent the cold air from blowing directly. The cold air is then delivered through the outer second air guide plate 2, which can effectively improve the user comfort in the windless mode. Furthermore, when a windless mode is achieved, the wind speed flowing through the air guide plate assembly 10 can be appropriately increased, for example, by increasing the fan speed of the air conditioner 1000, thereby improving the cooling capacity in the windless mode and solving problems such as poor cooling effect in the windless mode.

[0078] The air guiding device 100 according to a second aspect embodiment of the present invention will now be described.

[0079] like Figure 10 As shown, the air guiding device 100 includes at least one air guiding unit 101. Each air guiding unit 101 includes a drive mechanism 20 and an air guiding plate assembly 10 according to the first aspect embodiment of the present invention. The drive mechanism 20 drives the air guiding plate assembly 10 to rotate about a pivot axis 111. Thus, the rotation of the air guiding plate assembly 10 achieves a more effective air guiding effect, and the first air guiding plate 1 in the air guiding plate assembly 10 effectively reduces the blowing sensation index, improving user comfort. Furthermore, since the blowing sensation can be reduced, the air velocity flowing through the first vent 112 can be appropriately increased, thereby improving cooling capacity and achieving a better balance between airflow sensation and cooling effect.

[0080] In some embodiments, such as Figure 10As shown, at least one air guiding unit 101 includes multiple air guiding plate assemblies 10 arranged side by side. The pivot axes 111 of the multiple air guiding plate assemblies 10 are parallel. The drive mechanism 20 drives the multiple air guiding plate assemblies 10 to rotate synchronously. That is, each air guiding plate assembly 10 in the same air guiding unit 101 can be driven to rotate synchronously around its respective pivot axis 111 by the same drive mechanism 20. This simplifies the structure, reduces the number of drive structures, lowers costs, and ensures the consistency of synchronous rotation of the multiple air guiding plate assemblies 10, reducing control difficulty. Furthermore, by utilizing the multiple air guiding plate assemblies 10 arranged side by side working together, in the air guiding state, the multiple air guiding plate assemblies 10 arranged side by side can jointly guide the air, improving the overall air guiding effect and more effectively changing the air outlet direction. In the wind blocking state, the multiple air guiding plate assemblies 10 arranged side by side can jointly play a role in dispersing the air, thereby achieving both a good air dispersion effect and ensuring the air outlet volume.

[0081] Furthermore, it is understood that in order to achieve synchronous rotation of multiple air guide vane assemblies 10, the drive mechanism 20 can be configured in various forms. For example, in some examples, the drive mechanism 20 may include a drive motor and a connecting rod, with the drive motor pulling multiple air guide vane assemblies 10 to rotate synchronously via the connecting rod. Thus, the structure is simple and easy to implement. Of course, the present invention is not limited to this. For example, in other embodiments of the present invention, multiple drive mechanisms 20 can be used to drive each air guide vane assembly 10 to rotate separately. In this case, the control is relatively complex.

[0082] An air conditioner 1000 according to a third aspect embodiment of the present invention will now be described.

[0083] like Figure 11 As shown, the air conditioner 1000 according to an embodiment of the present invention may include: an air conditioner body 200 and an air guide device 100. The air conditioner body 200 has an air outlet area 201, and the air guide device 100 is an air guide device 100 according to a second aspect embodiment of the present invention, and the air guide device 100 is disposed at the air outlet area 201. Therefore, since the air guide device 100 includes the aforementioned air guide plate assembly 10, the first air guide plate 1 in the air guide plate assembly 10 can effectively reduce the draft sensation index, improving user comfort. Furthermore, since the draft sensation can be reduced, the air velocity flowing through the first vent 112 can be appropriately increased, thereby improving cooling capacity and achieving a better balance between draft sensation and cooling effect.

[0084] Furthermore, when the air guiding device 100 includes multiple air guiding plate assemblies 10 arranged side by side, in the air guiding state, the multiple air guiding plate assemblies 10 arranged side by side can be used to guide the air together, thereby improving the overall air guiding effect and more effectively changing the air outlet direction. In the wind blocking state, the multiple air guiding plate assemblies 10 arranged side by side can be used to disperse the air together, thereby achieving both a better air dispersion effect and ensuring the air outlet volume.

[0085] Furthermore, it should be noted that the specific type of air conditioner 1000 according to the embodiments of the present invention is not limited. It can be a split-type air conditioner indoor unit, such as a cabinet air conditioner or a wall-mounted air conditioner, or an integrated air conditioner, such as a portable air conditioner or an integrated air conditioner unit. For example, when applied to a wall-mounted air conditioner, the length direction F1 of the air guide plate assembly 10 can be horizontal, and multiple air guide plate assemblies 10 can be arranged side by side vertically. As another example, when applied to a cabinet air conditioner, the length direction F1 of the air guide plate assembly 10 can be vertical, and multiple air guide plate assemblies 10 can be arranged side by side horizontally. Moreover, once the specific type of air conditioner 1000 according to the embodiments of the present invention is determined, other components of the air conditioner 1000, such as heat exchangers, fans, etc., and their operation are known to those skilled in the art and will not be described in detail here. For simplicity, the following description will only use an application to a cabinet air conditioner as an example.

[0086] In some embodiments, such as Figure 11 As shown, the air outlet area 201 may include an upper area 201a and a lower area 201b arranged vertically. The air guiding device 100 includes two air guiding units 101, which are independent of each other and respectively located in the upper area 201a and the lower area 201b. That is, the upper area 201a is provided with one independently controlled air guiding unit 101, and the lower area 201b is provided with one independently controlled air guiding unit 101. The air guiding units 101 in the upper area 201a and the lower area 201b can be in the same state (e.g., both in the air guiding state or both in the air blocking state), or they can be in different states (e.g., one in the air guiding state and the other in the air blocking state). Thus, different practical application requirements can be met.

[0087] For example, when the air guide unit 101 in the upper region 201a switches to the wind-blocking state, and the air guide unit 101 in the lower region 201b switches to the air guide state, the air can be dispersed upwards and normally discharged downwards. Another example is when the air guide unit 101 in the lower region 201b switches to the wind-blocking state, and the air guide unit 101 in the upper region 201a switches to the air guide state, the air can be dispersed downwards and normally discharged upwards. Yet another example is when the air guide unit 101 in the upper region 201a switches to the wind-blocking state, and the air guide unit 101 in the lower region 201b also switches to the wind-blocking state, the air can be dispersed both upwards and downwards.

[0088] For example, in some embodiments, such as Figure 11 As shown, each air guiding unit 101 includes multiple air guiding plate assemblies 10 arranged side by side in a horizontal direction. That is, the length direction F1 of each air guiding plate assembly 10 is vertical, and the multiple air guiding plate assemblies 10 in one air guiding unit 101 can be arranged horizontally. Thus, the multiple air guiding plate assemblies 10 in one air guiding unit 101 can be driven by the linkage of the drive mechanism 20 to rotate left and right simultaneously to guide the air, thereby realizing the switching and adjustment of the wind blocking state and the air guiding state of each air guiding plate assembly 10. As a result, the number of drive mechanisms 20 can be minimized, which can simplify the structure and reduce costs. It can also reduce the number of drive motors and matching drive connectors used, thereby simplifying the structure and reducing costs.
