Description

Technical Field

[0001] This application relates to the field of air conditioning, and more particularly to an air guide plate structure and an air conditioner. Background Technology

[0002] Currently, ducted air handling units on the market are usually installed by embedding them into the ceiling. However, ducted air handling units typically only have one air outlet, and the air outlet is fixed during installation. In other words, when using a ducted air handling unit, it can only supply air in one direction.

[0003] In existing residential buildings, the spatial layout often includes two different functional areas within a single space, such as a living room and dining room connected together. Since ducted air conditioning units are typically fixed in position after renovation and can only supply air in one direction, the user experience for users in different functional areas of the same space is relatively poor.

[0004] To address this, a new type of ducted air handling unit has emerged, which is equipped with dual or multiple air outlets. Depending on the user's actual needs, different air outlets can be used in real time for blowing air. For unused air outlets, multiple baffles are usually used to block and close them.

[0005] However, when unused air outlets are covered by multiple baffles, gaps may appear between the baffles, leading to air leakage. Since there is a temperature difference between the air flowing through the duct unit and the ambient temperature, condensation may occur at the unused air outlets. The condensate water may flow into the duct unit and cause damage to the equipment, or drip into the room and damage the walls or indoor items. Utility Model Content

[0006] This application provides an air guide plate structure and an air conditioner to solve the problem of air leakage between air guide plates in the prior art.

[0007] In a first aspect, this application provides an air guide plate structure for use in an air conditioner, wherein the air conditioner is provided with an air outlet, and the air guide plate structure includes: a first air guide plate and a second air guide plate.

[0008] The fixed ends of the first and second air guide plates are rotatably fixed to both sides of the air outlet; the free ends of the first and second air guide plates can be rotated to overlap and close the air outlet or separate to open the air outlet.

[0009] The first air guide plate is provided with an overlap groove, and the second air guide plate is provided with an overlap member on the first side facing the air outlet. The overlap member can be inserted into the overlap groove and abut against the inner wall of the overlap groove for sealing.

[0010] Optionally, the overlapping member is a convex rib structure, which includes a first overlapping side perpendicular to the first side of the second air guide plate and a second overlapping side at an angle to the first side of the second air guide plate.

[0011] Along the air outlet's airflow direction, the distance between the first overlapping side and the second overlapping side gradually decreases.

[0012] Optionally, the second air guide plate is mounted on a mounting platform, and the mounting platform has a mounting surface in the direction from the fixed end of the second air guide plate to the free end;

[0013] A connecting part is provided at the bottom of the second overlapping side of the convex rib structure, and the connecting part is fixed to the mounting surface; a return gap is provided between the bottom of the convex rib structure and the second air guide plate.

[0014] Optionally, the overlap groove is a U-shaped groove, the two sidewalls of the U-shaped groove are parallel, and the two sidewalls correspond to the positions of the first overlap side and the second overlap side on the convex rib structure, respectively.

[0015] The width between the two sidewalls of the U-shaped groove is greater than the width between the first overlapping side and the second overlapping side at the end position of the convex rib structure, and less than the width between the first overlapping side and the second overlapping side at the bottom position of the convex rib structure.

[0016] Optionally, the two sidewalls of the U-shaped groove include: a first sidewall and a second sidewall with a height less than that of the first sidewall, wherein the position of the second sidewall corresponds to the position of the second overlapping side of the convex rib structure.

[0017] Optionally, a cover plate is provided at the free end of the second air guide plate, and a backflow gap is provided between the bottom of the convex structure and the cover plate.

[0018] Optionally, the end of the convex ridge structure is provided with an elastic abutment member;

[0019] When the first air guide plate overlaps with the second air guide plate, the elastic abutment on the convex rib structure abuts and seals against the bottom of the overlap groove.

[0020] Optionally, the overlapping member is an elastic member.

[0021] Optionally, the width of the reflux gap is between 2.5 mm and 4 mm.

[0022] Optionally, when the free ends of the first air guide plate and the second air guide plate overlap, the distance between the first overlapping side and the end face of the free end of the first air guide plate is the fitting distance, which is equal to 1.5 times to 2.5 times the return gap.

[0023] Optionally, the width of the sealing gap is less than or equal to 0.5 mm.

[0024] In a second aspect, an air conditioner is provided, wherein the air conditioner includes: a housing, and an air inlet cavity and an air outlet cavity disposed and connected within the housing, the air inlet cavity including an air inlet, the air outlet cavity including: at least two air outlets, and a heat exchanger disposed within the air outlet cavity;

[0025] At least one of the air outlets is provided with an air guide plate structure as provided in any of the foregoing embodiments.

[0026] Optionally, the at least two air outlets include: a first air outlet and a second air outlet, wherein the second air outlet and the air inlet are located on the same side of the housing; the opening direction of the first air outlet is perpendicular to the opening direction of the air inlet;

[0028] The technical solutions provided in this application have the following advantages compared with the prior art:

[0029] The air guide plate structure provided in this application embodiment allows the overlapping member of the second air guide plate to slide into the overlapping groove along the surface of the first air guide plate when the two air guide plates are rotated to the closed position. After being deformed by pressure, the overlapping member forms a surface contact with the groove wall, eliminating the contact gap between traditional rigid baffles. During air conditioning operation, the overlapping member ensures that the sealing surface remains tightly pressed, maintaining an effective seal even if the air guide plate experiences slight displacement due to airflow impact. In the closed state, the free ends of the two air guide plates form a continuous covering surface, completely blocking the airflow channel of the air outlet.

[0030] Compared to existing technologies, current baffles use a direct planar butt joint method, resulting in millimeter-level assembly gaps at the contact surfaces. This solution transforms planar contact into three-dimensional curved surface contact through the three-dimensional fit of overlapping parts and overlapping grooves, increasing the contact area and thus improving airtightness.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] 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 scope of 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.

[0044] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0045] In existing technologies, ducted air handling units typically employ a single air outlet structure, meaning the outlet direction is fixed and cannot be adjusted after installation. When multiple functional areas exist within the same space, a single air supply direction is insufficient to meet diverse needs. While dual-outlet models can switch air supply directions, gaps exist between multiple baffles when unused outlets are closed, leading to air leakage. During air conditioning operation, the temperature difference between the hot / cold air and the ambient environment causes condensation at the leak points. Accumulated condensate may damage equipment or indoor items.

[0046] To address these issues, researchers discovered that traditional baffle structures suffer from a rigid contact surface that cannot adapt to deformation. Through numerous experiments, they found that an elastic sealing structure can compensate for gaps caused by assembly tolerances. By analyzing the movement trajectory of the air guide plate, they proposed a mating method between the overlapping component and the overlapping groove, utilizing elastic deformation to eliminate gaps at the contact surface.

[0047] like Figure 1 The diagram shown is a structural schematic of an air conditioner according to an embodiment of this application. This air guide plate structure is applied in an air conditioner. (See attached image.) Figure 1 As shown, the air conditioner 100 includes: a housing 200, a fan 300 and a heat exchanger 400 disposed in the housing 200. The air inlet of the fan 300 is located on the left side or below. An air outlet cavity 500 is provided inside the housing 200. The fan 300 blows the air from the air inlet through the air outlet cavity 500 to the heat exchanger 400. The air after heat exchange in the heat exchanger 400 is blown out from the air outlet.

[0048] In this embodiment, the air conditioner 100 is provided with at least one air outlet, see [link to relevant documentation]. Figure 1 As shown in the figure, two air outlets are provided. The air outlets of the air conditioner 100 include a first air outlet 600 and a second air outlet 700. The first air outlet 600 is a front air outlet, and its position is opposite to the air outlet direction of the air outlet cavity 500 (the direction in which the fan faces the heat exchanger in the figure, i.e., from left to right). The second air outlet 700 is a lower air outlet, and its position is at an angle to the air outlet direction of the air outlet cavity 500. In other embodiments, the air conditioner 100 may also be provided with three or more air outlets, for example, in the direction of the front air outlet, the lower air outlet, and side air outlets.

[0049] The air guide plate structure provided in this application embodiment can be installed at any air outlet position of the air conditioner 100. See [link / reference] Figure 1 As shown, in Figure 1 In the embodiment shown, the air guide plate structure is illustrated by taking the installation at the first air outlet 600 as an example.

[0050] Figure 2 for Figure 1 An enlarged schematic diagram of A when the first and second air guide plates overlap. Figure 3 for Figure 1 An enlarged schematic diagram of A when the first and second air guide plates separate; Figure 4 This is a partial structural diagram of the free end of the second air guide plate. Figure 5 This is a three-dimensional structural diagram of a boss on the second air guide plate. Figure 6 This is a schematic diagram of another three-dimensional structure of the boss on the second air guide plate.

[0051] See Figures 2-6As shown in the embodiment of this application, the air guide plate structure includes: a first air guide plate 11 and a second air guide plate 12, wherein the first air guide plate 11 has a first fixed end 111 and a first free end 112, and the second air guide plate has a second fixed end 121 and a second free end 122, and the first fixed end 111 of the first air guide plate 11 and the second fixed end 121 of the second air guide plate 12 are rotatably fixed at both sides of the air outlet 600. Figure 1 As can be seen, the first fixed end 111 of the first air guide plate 11 is fixed to the upper side of the air outlet 600, and the second fixed end 121 of the second air guide plate 12 is fixed to the lower side of the air outlet 600. The first fixed end 111 and the second fixed end 121 can be a rotating shaft, which can be easily snapped into the housing on the side of the air outlet 600.

[0052] The free ends of the first air guide plate 11 and the second air guide plate 12 can be rotated to overlap and close the air outlet, or separated to open the air outlet 600. (See also...) Figure 2 The diagram shows the structure when the first air guide plate 11 and the second air guide plate 12 overlap. (See attached diagram.) Figure 3 The diagram shows the structure when the first air guide plate 11 and the second air guide plate 12 are separated. (See also...) Figure 7 The diagram shown is a structural schematic when the first and second air guide plates are not fully open. Figure 7 In the middle, the first air outlet 600 was fully opened.

[0053] In this embodiment, the first air guide plate 11 is provided with an overlapping groove 113, and the second air guide plate 12 has an overlapping member 123 on its first side surface 1222 facing the first air outlet 600. The overlapping member 123 can be inserted into the overlapping groove 113 and abuts and seals against the inner wall of the overlapping groove 113. In this embodiment, the abutment can be achieved by one or more of the overlapping member's top end, side wall, etc., abutting against the inner wall of the overlapping groove 113.

[0054] The overlap groove refers to a recessed structure located inside the free end of the first air guide plate. It can be implemented using a U-shaped groove or a dovetail groove, and is used to guide the overlap component into place and form a contact surface. The overlap component is a sealing part with deformation capability, which can be implemented using a silicone strip with raised ridges or an elastic metal sheet. Its deformation can compensate for assembly errors of the air guide plate.

[0055] Specifically, when the two air guide vanes rotate to the closed position, the overlapping member of the second air guide vane slides into the overlapping groove along the surface of the first air guide vane. After being deformed under pressure, the overlapping member forms a surface contact with the groove wall, eliminating the contact gap between traditional rigid baffles. During air conditioning operation, the continuous elasticity of the overlapping member keeps the sealing surface tightly pressed together, maintaining an effective seal even if the air guide vanes experience slight displacement due to airflow impact. In the closed state, the free ends of the two air guide vanes form a continuous covering surface, completely blocking the airflow passage of the air outlet.

[0056] Compared to existing technologies, current baffles use a direct planar butt joint method, resulting in millimeter-level assembly gaps at the contact surfaces. This solution transforms planar contact into three-dimensional curved surface contact through the three-dimensional fit of overlapping parts and overlapping grooves, increasing the contact area and thus improving airtightness.

[0057] Through the above technical solution, this application effectively eliminates the contact gap when multiple air guide plates are closed, reduces air leakage, and avoids condensation caused by air leakage.

[0058] In the embodiments of this application, see Figure 2 and Figure 3 As shown, the overlapping member 123 has a convex ridge structure. The convex ridge structure includes a first overlapping side 1231 and a second overlapping side 1232, wherein the first overlapping side 1231 is perpendicular to the first side 1222 of the second air guide plate 12, and the second overlapping side 1232 is at an angle to the first side 1222 of the second air guide plate 12.

[0059] Furthermore, along the air outlet direction of the first air outlet 600, which is also the direction in which the second side faces, the distance between the first overlapping side 1231 and the second overlapping side 1232 gradually decreases.

[0060] The convex ridge structure refers to an elastic protrusion on the first side of the second air guide plate. It can be made of rubber or silicone through molding, or it can be made of the same material as the second air guide plate, with a trapezoidal or triangular cross-section. This structure achieves tight contact with the overlapping groove through elastic deformation. The first overlapping side refers to the side of the convex ridge structure perpendicular to the surface of the second air guide plate. It can be a planar structure, forming surface contact with the corresponding sidewall of the overlapping groove during the overlapping process to ensure reliable sealing. The second overlapping side refers to the side of the convex ridge structure at an inclined angle to the surface of the second air guide plate. It can be a sloping structure with an inclination angle of 5° to 30°, generating progressive compression deformation when inserted into the overlapping groove to compensate for assembly tolerances. Furthermore, the gradually decreasing distance between the first and second overlapping sides refers to the wedge-shaped geometric feature formed by the convex ridge structure, which can be achieved through linear or curved transitions, generating continuously increasing contact pressure during the overlapping process. In this embodiment, the overlapping element can be an elastic element, for example, made of rubber or silicone.

[0061] Specifically, when the second air guide plate rotates to the position where it overlaps with the first air guide plate, the second overlapping side of the convex rib structure first contacts the inlet edge of the overlapping groove. As the second and first air guide plates continue to close, the tilt angle of the second overlapping side forces the convex rib structure to undergo elastic compression deformation, while the first overlapping side gradually adheres to the inner wall of the overlapping groove. During this process, the radial compressive force generated by the wedge structure causes the convex material to fill the assembly gap between the overlapping groove and the convex rib, eliminating local non-contact areas caused by manufacturing errors. When the air guide plate is fully closed, the first overlapping side forms a surface seal with the side wall of the overlapping groove, and the elastic restoring force of the second overlapping side further maintains the contact pressure, preventing airflow leakage from the overlapping interface.

[0062] Compared to existing technologies, traditional air guide plate sealing structures often employ rigid protrusions or independent sealing strips with planar contact, which are prone to localized gaps due to assembly errors or material deformation. This solution, however, utilizes a wedge-shaped ridge structure with inclined sides, which actively generates elastic deformation during the overlapping process. This not only compensates for component machining tolerances but also maintains continuous compression of the sealing interface through deformation recovery force, preventing air leakage caused by insufficient contact pressure. The application effectively solves the air leakage problem caused by loose contact at the air guide plate overlapping interface, prevents condensation at unused air outlets due to hot and cold air exchange, and avoids damage to equipment and the indoor environment caused by condensation.

[0063] In one embodiment of this application, a mounting platform 127 is disposed on the second air guide plate 12. The mounting platform 127 has a mounting surface (not shown in the figure) in the direction from the second fixed end 121 to the second free end 122 of the second air guide plate 12. A connecting portion 126 is disposed at the bottom of the second overlapping side surface 1232 of the convex rib structure, and the connecting portion 126 is fixed to the mounting surface. A return flow gap 124 is disposed between the bottom of the convex rib structure and the second air guide plate 12. See also... Figure 3 As shown, when a cover plate 125 is provided on the second air guide plate 12, the return gap 124 can also be provided between the cover plate 125 and the bottom of the convex structure.

[0064] The mounting platform refers to the raised structure on the surface of the second air guide plate, which can be achieved through injection molding or metal stamping. Its mounting surface extends along the rotation direction of the air guide plate, providing axial support for the raised structure. The connecting part refers to the fixing structure between the bottom of the raised structure and the mounting surface, which can be achieved through snap-fit ​​connections or adhesive bonding, limiting lateral displacement of the raised structure during overlap. The backflow gap refers to the gap between the bottom of the raised structure and the body of the second air guide plate, which can be achieved by allowing assembly tolerances or by incorporating elastic supports, allowing the raised structure to deform under pressure.

[0065] This application further proposes that the overlap groove is a U-shaped groove, the two side walls of the U-shaped groove are parallel, and the two side walls correspond to the positions of the first overlap side and the second overlap side on the convex rib structure, respectively; the width between the two side walls of the U-shaped groove is greater than the width between the first overlap side and the second overlap side at the end position of the convex rib structure, and less than the width between the first overlap side and the second overlap side at the bottom position of the convex rib structure.

[0066] In this embodiment, the overlap groove can be a U-shaped groove, with two parallel sidewalls corresponding to the positions of the first and second overlap sides on the convex ridge structure. Furthermore, the width between the two sidewalls of the U-shaped groove is greater than the width between the first and second overlap sides at the end position of the convex ridge structure, and less than the width between the first and second overlap sides at the bottom position of the convex ridge structure.

[0067] A U-shaped groove refers to a recessed structure with two parallel sidewalls, which can be achieved through injection molding or machining. It accommodates a protruding ridge structure and forms a sealing contact surface. The ends of the protruding ridge structure are positions 1, 2, 3, and 4 in the diagram, and can be achieved through a gradually narrowing bevel design, allowing for elastic deformation during insertion. The bottom of the protruding ridge structure refers to the root area near the mounting base, which can be achieved by fixing it to the mounting surface to ensure stable support at the root during deformation.

[0068] Specifically, when the convex rib structure is inserted into the U-shaped groove, its narrower end enters the groove first. At this point, the groove width is greater than the end width, preventing jamming. As the insertion depth increases, the wider bottom portion of the convex rib gradually enters the groove. Because the groove width is smaller than the bottom width, the overlapping sides of the convex rib are compressed by the groove wall, causing elastic deformation. The reaction force generated by the deformation causes the first overlapping side to form surface contact with the groove wall, while the second overlapping side creates a wedge-shaped pressing effect with the corresponding groove wall through its inclined angle. The presence of the backflow gap allows for a slight displacement at the root of the convex rib, which both relieves assembly stress and maintains continuous compression and sealing.

[0069] See Figure 2 or Figure 3 As shown, the two sidewalls of the U-shaped groove include: a first sidewall (the upper sidewall) and a second sidewall (the lower sidewall) with a height less than the first sidewall. The position of the second sidewall corresponds to the position of the second overlapping side of the convex rib structure.

[0070] When the air guide plate is closed, the first overlapping side of the convex rib structure forms a rigid contact with the first sidewall of the U-shaped groove, establishing an initial sealing interface. The reduced height design of the second sidewall allows the second overlapping side of the convex rib structure to undergo elastic deformation during insertion. During deformation, the contact pressure between the second overlapping side and the second sidewall gradually increases, which also increases the pressure between the first overlapping side and the first sidewall, resulting in a better sealing effect.

[0071] See Figure 3 and Figure 4 As shown, a cover plate 125 is provided on the free end of the second air guide plate 12. The thickness of the cover plate 125 is less than the thickness of the second air guide plate, and it is located on the side of the second air guide plate closer to the fan. As can be seen from the figure, when the first air guide plate and the second air guide plate overlap, a backflow gap is provided between the cover plate 125 and the bottom of the convex structure.

[0072] In this embodiment of the application, an elastic abutment 1235 is provided on the end 1234 of the convex rib structure. When the first air guide plate overlaps with the second air guide plate, the elastic abutment on the convex rib structure abuts and seals against the bottom of the overlap groove.

[0073] Elastic abutment parts refer to sealing components with elastic deformation capabilities. They can be made of silicone, rubber, or elastic plastic materials and are fixed to the end of the convex structure by snap-fit ​​or adhesive. Their function is to compensate for the assembly gap between the overlapping groove and the convex structure through elastic deformation when the air guide plate is closed.

[0074] Among them, the bottom abutment seal of the overlap groove refers to the surface contact between the elastic abutment member and the bottom surface of the inner wall of the overlap groove after being compressed. Specifically, the cross-sectional shape of the elastic abutment member can be designed to be arc-shaped or wedge-shaped so that it can completely fit the bottom of the groove under compression, thereby blocking the path of airflow leakage from the bottom.

[0075] This application further discloses an air conditioner 100, wherein the air conditioner 100 includes a housing 200 and an air inlet cavity 101 and an air outlet cavity 500 disposed within the housing and communicating with each other. The air inlet cavity 101 includes an air inlet (not shown in the figure), and the air outlet cavity 500 includes at least two air outlets, including a first air outlet 600 and a second air outlet 700 in the figure. A heat exchanger 400 is disposed within the air outlet cavity 500, and an air guide plate structure is disposed at at least one air outlet. See [reference needed]. Figure 1 As shown, an air guide structure is installed at the first air outlet 600.

[0076] The air guide plate structure includes a first air guide plate 11 and a second air guide plate 12. The first air guide plate 11 has a first fixed end 111 and a first free end 112, and the second air guide plate has a second fixed end 121 and a second free end 122. Both the first fixed end 111 and the second fixed end 121 of the first air guide plate 12 are rotatably fixed to opposite sides of the first air outlet 600. Figure 1 As can be seen, the first fixed end 111 of the first air guide plate 11 is fixed on the upper side of the first air outlet 600, and the second fixed end 121 of the second air guide plate 12 is fixed on the lower side of the first air outlet 600. The first fixed end 111 and the second fixed end 121 can be a rotating shaft, which can be easily snapped into the housing on the side of the first air outlet 600.

[0077] The free ends of the first air guide plate 11 and the second air guide plate 12 can be rotated to overlap and close the air outlet, or separated to open the first air outlet 600. (See also...) Figure 2 The diagram shows the structure when the first air guide plate 11 and the second air guide plate 12 overlap. (See attached diagram.) Figure 3 The diagram shows the structure when the first air guide plate 11 and the second air guide plate 12 are separated. (See also...) Figure 7 The diagram shown is a structural schematic when the first and second air guide plates are not fully open. Figure 7 In the middle, the first air outlet 600 was fully opened.

[0078] In one embodiment of this application, such as Figure 1 As shown, at least two air outlets include a first air outlet 600 and a second air outlet 700. The second air outlet and the air inlet are located on the same side of the housing (e.g., both located at the bottom of the housing). The opening direction of the first air outlet is perpendicular to the opening direction of the air inlet; for example, the opening direction of the first air outlet in the figure is to the right. The air guide plate structure is disposed on the first air outlet 600, and the second air guide plate 12 in the air guide plate structure can close the second air outlet 700 after rotation.

[0079] The casing refers to the external support structure of the air conditioner, which can be injection molded from metal or plastic, used to fix internal components and form a sealed space. The air inlet and outlet chambers refer to independent air duct areas separated by internal partitions, which can be welded or snap-fit ​​connected, used to guide airflow. At least two air outlets refer to openings located on different sides of the casing, specifically on the front and sides, used to deliver air in different directions. The heat exchanger is a component used for heat exchange between air and refrigerant, specifically a finned tube structure, installed in the air outlet chamber. The air guide plate structure refers to a mechanism consisting of a rotatable air guide plate and sealing components, specifically rotated by a shaft and drive motor, used to control the opening, closing, and sealing of the air outlets.

[0080] Through the above technical solution, this application effectively solves the problem of air leakage caused by the baffle not closing tightly in the air outlet of the dual-outlet air conditioner. By combining the linkage of the air guide plate and the elastic sealing structure, the path of airflow leakage from the non-use air outlet is blocked, avoiding condensation caused by temperature difference due to air leakage, and preventing condensate from entering the equipment or dripping into the indoor environment.

[0081] In practical use, such as Figures 1-7 As shown, the airflow distribution and sealing mechanism of the air guide plate structure under different operating conditions are illustrated. Figure 1 In this configuration, when the second air outlet 700 (i.e., the lower air outlet) is open, the first and second air guide plates are closed via a linkage mechanism, while the first air outlet 600 (i.e., the upper air outlet) is closed. At this time, airflow exits unidirectionally through the second air outlet 700. Because the movement directions of the first and second air guide plates are perpendicular to the airflow direction, they experience dynamic disturbances under the impact of the airflow. During this process, the backflow gap (i.e., backflow gap c) between the first and second air guide plates becomes a potential path for airflow leakage, with some airflow entering the internal space between the first and second air guide plates through this gap.

[0082] like Figure 2 As shown, the air guide plate sealing structure of the present invention achieves efficient airflow control through a multi-stage sealing design. Specifically, the width of the return gap c (i.e., the left-right direction in the figure) is strictly controlled within the range of ≤0.5mm. This tiny gap can effectively suppress the direct penetration of airflow. When the airflow enters the interior of the air guide plate through the return gap c, it will enter the preset return bend structure (i.e., return gap 124).

[0083] In this embodiment, a backflow gap is provided between the bottom of the convex ridge structure and the second air guide plate. The width of the backflow gap (i.e., the left-right direction in the figure) is set in the range of 2.5-4 mm, and its geometry is optimized through fluid dynamics design to produce a significant throttling effect on the airflow. Specifically, the ratio of the curvature radius to the diameter of the backflow bend is calculated to cause local pressure loss when the airflow passes through, thereby blocking about 30%-50% of the airflow from entering the subsequent channel, forming a primary structural seal.

[0084] In addition, when the free ends of the first air guide plate and the second air guide plate overlap, the distance between the first overlapping side and the end face of the free end of the first air guide plate is the fitting distance. The fitting distance b when the first air guide plate and the second air guide plate overlap is designed to be in the range of 1.5a to 2.5a, which improves the sealing effect.

[0085] Dynamic adaptive design: Under airflow impact, the first and second air guide vanes may undergo slight displacement (typically 0.1–0.3 mm). Due to the special geometry of the interlocking structure, this displacement causes dynamic contraction of the return gap c and the interlocking distance b between the first and second air guide vanes, forming a secondary structural seal. This mechanism achieves dynamic enhancement of sealing performance through mechanical self-adaptation, effectively offsetting the risk of seal failure caused by airflow disturbance.
