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 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 that can be rotatably closed or opened by the air outlet;

[0008] A rotatable sealing plate is provided on the first air guide plate, and two sealing plate limiting members are provided on both sides of the air outlet and at positions corresponding to the ends of the sealing plate; the sealing plate limiting members are provided with grooves facing the interior of the air conditioner.

[0009] When the first and second air guide plates close the corresponding air vents, the sealing plate is inserted into the groove and rotates to fit against the outer surface of the first and second air guide plates.

[0010] Optionally, the fixed ends of the first and second air guide plates can be rotatably fixed to the two sides of the corresponding air outlet; the free ends of the first and second air guide plates can be rotated and overlapped on the sealing plate limiting member, or moved away from the sealing plate limiting member.

[0011] Optionally, the sealing plate is fixed to the side of the first air guide plate facing the air guide limiting member by a rotating shaft; and the rotating shaft is spaced apart from the free end of the first air guide plate.

[0012] Optionally, a reset spring is provided on the rotating shaft; when the sealing plate is away from the sealing plate limiting member, it is in the initial state, and in the initial state, the sealing plate is subject to the force of the reset spring and a limiting angle is provided between it and the first air guide plate; after the sealing plate is inserted into the groove, it is rotated and attached to the outer side of the overlapping position of the first air guide plate and the second air guide plate by the squeezing force of the groove.

[0013] Optionally, the groove is a U-shaped structure with sloping sidewalls, and the distance between the two sidewalls of the U-shaped structure gradually increases along the opening direction of the groove.

[0014] Optionally, the angle between the slope of the groove and the bottom plane is 100°-160°.

[0015] Optionally, the width of the sealing plate matches the width of the opening of the groove. After the sealing plate is inserted into the groove, the side of the sealing plate that overlaps with the first air guide plate and the second air guide plate protrudes from the opening end face of the groove. Alternatively, the side of the sealing plate that overlaps with the first air guide plate and the second air guide plate is flush with the opening end face of the groove.

[0016] Optionally, the inner wall of the groove has an arc-shaped structure, and the width of the arc-shaped structure gradually increases from the bottom toward the opening direction.

[0017] Secondly, this application provides an air conditioner, 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;

[0018] At least one of the air outlets is provided with an air guide plate structure as provided in any of the foregoing embodiments.

[0019] 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;

[0020] The air guide plate structure is disposed on the first air outlet, and the second air guide plate in the air guide plate structure can close the second air outlet after rotating away from the sealing plate limiting member.

[0021] The air guide plate structure provided in this application embodiment allows the first air guide plate to move towards the air outlet when the first and second air guide plates rotate to their closed positions. During this movement, the end of the sealing plate contacts the groove sidewall of the sealing plate limiting member and rotates under the guidance of the groove. As the first and second air guide plates fully close, the sealing plate rotates to a state where it is completely in contact with the outer surfaces of the first and second air guide plates, forming a continuous surface contact seal that seals the assembly gap or seam between the first and second air guide plates.

[0022] Through the above technical solution, this application effectively solves the air leakage problem of dual-outlet air conditioners when the unused outlets are closed. During the closing process, the sealing plate is forced to rotate by the groove, ensuring a seamless fit with the outer surface of the air guide plate, blocking the leakage path of airflow through the joints of the air guide plate. This sealing structure avoids temperature exchange caused by air leakage, fundamentally eliminating the necessary conditions for condensation and protecting the internal components of the air conditioner and the indoor environment from damage by condensate.

Detailed Implementation

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In existing technologies, ceiling-mounted ducted air conditioning units typically have only a single fixed air outlet, which cannot meet the air supply needs of multiple functional areas within the same space. When using a multi-outlet design, the traditional baffle structure has assembly gaps between adjacent baffles when unused outlets are closed, leading to air leakage. When there is a temperature difference between the airflow inside the air conditioner and the ambient temperature, condensation is likely to occur at the leakage points, and the accumulation of condensate may damage the equipment or indoor items. For example, in a space connecting the living room and dining room, a single air outlet cannot meet the air supply needs of both areas, and sealing defects in the baffles of multi-outlet air conditioners can cause condensation problems.

[0042] To address these issues, researchers discovered that the gaps in traditional multi-baffle structures stemmed from mechanical assembly clearances. Analysis revealed that fixed gaps could be eliminated during the air guide plate's closure process. Based on this idea, a movable sealing component was added to the air guide plate system, utilizing forced guidance during mechanical movement to achieve a gapless seal.

[0043] 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 1As 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 disposed 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.

[0044] 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 corresponds to the air outlet direction of the air outlet cavity 500. 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.

[0045] 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 10 is illustrated by taking the installation at the first air outlet 600 as an example.

[0046] See Figures 1-3 As shown, the air guide plate structure 10 in the figure may include: a first air guide plate 11, a second air guide plate 12, and a sealing plate limiting member 13. Both the first air guide plate 11 and the second air guide plate 12 can be fixed at the first air outlet position via a rotating shaft, and can rotate within the first air outlet's vertical plane and inside the first air outlet. Rotation can close or open the first air outlet. A rotatable sealing plate 110 is provided on the first air guide plate 11, and two sealing plate limiting members 13 are provided on both sides of the first air outlet 600. 14 in the figure shows the gap between the first air guide plate 11 and the second air guide plate 12. (See Figure 14 for details.) Figure 2 As shown, the sealing plate limiting member 13 is located on both sides along the length direction of the first air guide plate or the second air guide plate, that is... Figure 2 In the middle, the left and right sides of the first air outlet 600, and corresponding to the positions of the two ends of the sealing plate 110. Optionally, in the embodiment of this application, the width of the first air guide plate 11 and the second air guide plate 12 ( Figure 2 Since the width direction (vertical direction) and length direction (horizontal direction) are equal, the sealing plate limiting member 13 is located in the middle of the vertical sides of the first air outlet 600.

[0047] See Figure 1 and Figure 4As shown, the sealing plate limiting member 13 includes a first end 132 and a second end 131, wherein a groove is provided between the first end 132 and the second end 131 on the sealing plate limiting member 13, and the groove faces the interior of the housing 200. The first end 132 can be directly fixed to the housing 200, and the second end 131 can be a certain elastic end, which is convenient to play a certain buffering role when in contact with the sealing plate. In other embodiments of this application, the second end 131 can also be directly fixed to the housing 200. When the first air guide plate 11 and the second air guide plate 12 close the corresponding first air outlet 600, the sealing plate 110 can be inserted into the groove in the sealing plate limiting member 13, and can rotate and fit against the outer surface of the first air guide plate 11 and the second air guide plate 12 within the groove. Figure 1 The right side is the outer side.

[0048] In this embodiment, the first and second air guide plates refer to two independently rotating plate-like structures, specifically mounted on both sides of the air outlet via a shaft connection, achieving air outlet opening and closing through rotational movement. Their function is to form a basic sealing layer, covering the main opening area of ​​the air outlet. The sealing plate is a movable plate on the first air guide plate, specifically connected by a hinge, generating rotational displacement during the closing process of the first air guide plate. Its function is to form a second dynamic seal, sealing the assembly gap between the first and second air guide plates. The sealing plate limiting component refers to a positioning part fixed on both sides of the air outlet, specifically made of injection-molded plastic, with an internal guide structure. Its function is to constrain the movement trajectory of the sealing plate, ensuring precise positioning during closing. The groove refers to a recessed structure provided on the limiting component, specifically with a U-shaped cross-section, the opening facing the interior of the air conditioner's casing. Its function is to guide the end of the sealing plate into a predetermined position and control the rotation angle of the sealing plate through the sidewall shape.

[0049] Specifically, when the first and second air guide plates rotate to their closed positions, the first air guide plate moves the sealing plate towards the air outlet. During this movement, the end of the sealing plate contacts the groove sidewall of the sealing plate limiting component and rotates under the guidance of the groove. As the first and second air guide plates are fully closed, the sealing plate rotates to a state where it is completely in contact with the outer surfaces of the first and second air guide plates, forming a continuous surface contact seal that seals the assembly gap or gap between the first and second air guide plates.

[0050] Through the above technical solution, this application effectively solves the air leakage problem of dual-outlet air conditioners when the unused outlets are closed. During the closing process, the sealing plate is forced to rotate by the groove, ensuring a seamless fit with the outer surface of the air guide plate, blocking the leakage path of airflow through the joints of the air guide plate. This sealing structure avoids temperature exchange caused by air leakage, fundamentally eliminating the necessary conditions for condensation and protecting the internal components of the air conditioner and the indoor environment from damage by condensate.

[0051] See Figures 2-5 As shown, the first air guide plate 11 includes: a sealing plate 110, a first fixed end 111 and a first free end 112. The first fixed end 111 can be rotatably fixed at both sides of the corresponding air outlet. For example, the first fixed end 111 of the first air guide plate can be fixed at the top side of the first air outlet 600.

[0052] The second air guide plate 12 includes a second fixed end 121 and a second free end 122. The second fixed end 121 can be rotatably fixed at both sides of the corresponding air outlet. For example, the second fixed end 121 of the second air guide plate can be fixed at the bottom side of the first air outlet 600.

[0053] After the free ends of the first air guide plate 11 and the second air guide plate 12 are rotated, they can overlap on the sealing plate limiting member 13 or move away from the sealing plate limiting member 13.

[0054] In this embodiment, the fixed end being rotatably fixed refers to the connection between the air guide plate and the edge of the air outlet using a rotatable mounting structure, specifically achieved using a hinge or pivot, ensuring stable rotation of the air guide plate around the fixed end. The free end overlapping the sealing plate limiting member refers to the end of the air guide plate forming contact support with the sealing plate limiting member when closed, specifically achieved through a snap-fit ​​or groove engagement, used to limit the offset of the sealed plate's closed position. The free end moving away from the sealing plate limiting member refers to the end of the air guide plate disengaging from the constraint of the limiting member when open, specifically achieved through a drive mechanism or manual operation, to expand the opening range of the air outlet.

[0055] Specifically, the fixed end of the air guide plate is mounted on both sides of the air outlet via a rotating shaft, forming a stable axis of rotation and preventing seal failure due to instability of the fulcrum during movement. In the closed state, the free end overlaps the surface of the sealing plate's limiting component, eliminating vibrations caused by airflow impact through rigid contact, thus reducing gaps in the closed state. In the open state, the free end is released from the limiting component, allowing the air guide plate to freely adjust its angle to adapt to different air delivery requirements. The overlapping surface of the sealing plate's limiting component and the contact area of ​​the free end of the air guide plate form a mechanical limit, further constraining the displacement of the air guide plate after closure and ensuring precise fit between the sealing plate and the groove.

[0056] See Figure 3As shown in the embodiment of this application, the sealing plate 110 is fixed on the side of the first air guide plate 11 facing the sealing plate limiting member 13 by the rotating shaft 113, that is, the right side in the figure. The rotating shaft 113 and the first free end 112 of the first air guide plate 11 are spaced apart, that is, there is a gap between the rotating shaft 113 and the end of the first air guide plate 11. So when the sealing plate 110 is flipped to be parallel to the first air guide plate 11, a part of the sealing plate 110 is in contact with the side of the first air guide plate 11.

[0057] The rotating shaft being fixed to the side of the first air guide plate facing the air guide limiting component means that the rotating shaft is installed on the surface of the first air guide plate near the air guide limiting component. This can be achieved by welding or bolting, ensuring that the rotation trajectory of the sealing plate aligns with the groove of the air guide limiting component. The spacing between the rotating shaft and the free end of the first air guide plate means that the rotating shaft is installed at a certain distance from the end of the first air guide plate. This can be achieved by adjusting the installation position of the rotating shaft or extending the length of the first air guide plate, preventing motion interference between the free end and the sealing plate during rotation.

[0058] To ensure that the sealing plate can be easily inserted into the groove in the sealing plate limiting member when it is in contact with the sealing plate limiting member, in this embodiment of the application, a return spring (not shown in the figure) is further proposed to be provided on the rotating shaft 113.

[0059] The function of the return spring is to maintain a limiting angle between the sealing plate and the first air guide plate when the sealing plate is not in contact with the sealing plate limiting component. For example, the limiting angle can be 60-90 degrees, that is, the angle between the sealing plate and the part of the first free end on the first air guide plate can be 60-90 degrees. For example, see: Figure 3 As shown, the sealing plate can be kept perpendicular to the first air guide plate.

[0060] In practical applications, the sealing plate 110 is in its initial state when it is away from the sealing plate limiting member. In the initial state, the sealing plate 110 is subject to the force of the reset spring and a limiting angle is set between it and the first air guide plate. After the sealing plate 110 is inserted into the groove, it is subjected to the squeezing force of the groove, which can counteract the action of the reset spring and thus rotate and fit against the outer side of the overlapping position of the first air guide plate and the second air guide plate.

[0061] In this embodiment, the reset spring refers to a mechanical element with elastic restoring force, specifically a helical spring or a torsion spring. Its function is to provide a continuous reset torque to the sealing plate to maintain its initial state. The initial state refers to the natural posture of the sealing plate when it is not subjected to external force, which can be achieved by adjusting the spring preload. This state ensures that the sealing plate maintains rigid support perpendicular to the air guide plate when not in operation. Furthermore, the groove pressing force refers to the pressure exerted by the groove sidewall on the sealing plate, which can be achieved through the sloping structure or guide surface of the groove inner wall. Its function is to guide the sealing plate to rotate and conform to the outer surfaces of the first and second air guide plates during insertion into the groove.

[0062] Specifically, when the air guide plate is in the open state, the return spring forces the sealing plate to maintain its initial posture perpendicular to the first air guide plate, at which point the sealing plate is in a free state without external force. When the air guide plate begins to close, the sealing plate moves with the air guide plate and gradually inserts into the groove. The sidewall of the groove applies pressure to the sealing plate, which overcomes the torque of the return spring, causing the sealing plate to rotate around the axis. As the air guide plate closes completely, the sealing plate is finally pressed and adheres to the outer surface of the overlap between the first and second air guide plates, forming a surface contact seal. When the air guide plate reopens, the return spring drives the sealing plate to automatically rotate back to its initial vertical state, providing a positioning reference for the next closing action.

[0063] Compared with existing technologies, traditional air guide plate sealing structures lack automatic reset functions, which can easily lead to positional displacement or poor fit of the sealing plate after multiple opening and closing. This solution achieves dynamic self-calibration of the sealing plate through the elastic recovery characteristics of the reset spring, avoiding manual adjustment or the introduction of complex drive mechanisms.

[0064] Through the above technical solution, this application solves the problem that the sealing plate cannot automatically reset when the air guide plate is opened, realizes the precise positioning and dynamic fitting of the sealing plate during the closing process, simplifies the mechanical complexity of the sealing structure, and improves the reliability and sealing performance of the air guide plate system.

[0065] In the embodiments of this application, see Figure 4 As shown, the inner wall of the groove can also be an arc-shaped structure, with the width of the arc-shaped structure gradually increasing from the bottom towards the opening.

[0066] In other embodiments, the groove adopts a U-shaped structure, with sloping sidewalls that gradually increase in distance between the two sidewalls along the groove opening direction. In this embodiment, the angle between the sloping sidewall and the bottom plane of the U-shaped groove is between 100° and 160°.

[0067] The U-shaped structure refers to a groove-like structure with a bottom and two side walls, which can be achieved by metal stamping or injection molding. Its bottom width matches the thickness of the sealing plate, accommodating the sealing plate and limiting its lateral displacement. The sloping side walls form an angle with the bottom of the groove, achieved using linear slopes or curved transitions, with the angle ranging from 15 to 60 degrees, serving as a guide during sealing plate insertion. Gradually increasing spacing refers to a linear or non-linear expansion of the distance between the side walls as it extends from the bottom of the groove towards the opening. This can be achieved by changing the side wall angle or curvature, with the opening width, for example, being 1.5-3 times wider than the bottom of the groove, forming a gradually widening channel to compensate for assembly errors.

[0068] Specifically, as the sealing plate moves into the groove, the ramped sidewalls first contact the edge of the sealing plate and guide it to slide in along a predetermined trajectory. As the insertion depth increases, the gradually increasing sidewall spacing allows for a certain amount of lateral offset in the sealing plate, preventing jamming due to assembly errors. When the sealing plate is fully inside the bottom of the groove, the ramps on both sidewalls apply radial pressure to the sealing plate through geometric constraints, forcing it to rotate around the axis until it is completely in contact with the outer surface of the air guide plate. During this process, the rotation angle of the sealing plate is determined by both the ramp inclination angle and the change in sidewall spacing, enabling self-correction and clamping actions without relying on an external drive device.

[0069] Compared to existing technologies, traditional groove designs, which employ vertical sidewalls or fixed widths, require precise alignment during sealing plate insertion and cannot automatically compensate for positional deviations. They necessitate the use of additional devices such as springs or motors to forcibly adjust the sealing plate angle. This solution, however, utilizes the synergistic effect of sloping sidewalls and gradually widening gaps to simultaneously complete guidance, tolerance compensation, and rotational drive during the sealing plate's movement, eliminating reliance on complex drive mechanisms. This structure achieves sealing without an additional power source, reducing manufacturing costs and improving system reliability.

[0070] In this embodiment of the application, in order to ensure the sealing effect, the width of the sealing plate matches the width of the opening position of the groove. After the sealing plate is inserted into the groove, the side of the sealing plate that is in contact with the first air guide plate and the second air guide plate protrudes from the opening end face of the groove, or the side of the sealing plate that is in contact with the first air guide plate and the second air guide plate is flush with the opening end face of the groove.

[0071] The matching of the width of the sealing plate to the width of the groove opening means that their lateral dimensions form a clearance fit or interference fit. This can be achieved through machining with tolerances controlled within ±0.5 mm. This design eliminates lateral gaps when the sealing plate is inserted into the groove. The sealing plate protruding from the groove opening end face means that the outer surface of the sealing plate extends 0.1-2 mm beyond the groove opening plane. This can be achieved by adjusting the sealing plate thickness or the groove depth. This structure generates elastic clamping force when the air guide plate is closed. The sealing plate side being flush with the groove opening end face means that their contact surfaces are on the same plane. This can be achieved by setting a limiting step or a positioning reference surface. This structure ensures that there is no height difference between the contact surfaces.

[0072] Specifically, when the air guide plate is closed, the sealing plate is driven into the groove. Under width matching conditions, a gapless fit is formed between the sealing plate and the sidewall of the groove, preventing lateral air leakage. When the side of the sealing plate protrudes from the end face of the groove opening, the sealing plate undergoes elastic deformation due to the pressure of the groove during the air guide plate closure process, continuously pressing against the outer surface of the air guide plate to form a dynamic seal. When the side of the sealing plate is flush with the end face of the groove opening, the contact surfaces of the two achieve a static seal through planar contact. Both implementations, through precise mechanical matching, completely block the leakage path of air between the sealing plate and the groove when the air guide plate is closed.

[0073] Figure 6 The diagram provided in this application embodiment shows the first air guide plate in multiple rotating states, which is used to facilitate the explanation of the cooperation relationship between the sealing plate and the sealing plate limiting member.

[0074] As shown in the figure, in the first state, the sealing plate 110 is perpendicular to the first air guide plate 11 under the action of the return spring. The first air guide plate 11 rotates to the right to close the first air outlet. In the second state, the end of the sealing plate 110 contacts the side wall of the groove of the sealing plate limiting member 13. The side wall of the groove provides a squeezing force, which counteracts the elastic force of the return spring, causing the sealing plate 110 to rotate downward. In the third state, the sealing plate 110 continues to rotate under the squeezing and guiding action of the groove of the sealing plate limiting member 13. Until the fourth state, the sealing plate 110 is completely in contact with the outer surfaces of the first air guide plate 11 and the second air guide plate 12.

[0075] The left side of the sealing plate 110 can be flush with or protrude from the opening of the groove, so that the sealing plate 110 can contact and abut against the outer sides of the first air guide plate 11 and the second air guide plate 12 to seal the seal between them.

[0076] Figures 7-9 The first air guide plate provided in this embodiment of the application gradually rotates from the position of closing the first air vent to the position of opening the first air vent.

[0077] Figure 10 and Figure 11 The second air guide plate provided in the application embodiment gradually rotates from the position where the first air vent is closed to the position where the first air vent is open. Furthermore, see... Figure 10 As shown, after the first air vent is opened, the second air guide plate can be flipped to close the second air vent.

[0078] This application further discloses an air conditioner 100, including 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 10 is disposed at at least one air outlet. See [reference needed] Figure 1 As shown, an air guide plate structure 10 is provided at the first air outlet 600.

[0079] The air guide plate structure 10 includes a first air guide plate 11 and a second air guide plate 12 that can rotate to close or open the air outlet. The first air guide plate 11 is provided with a sealing plate 110, and sealing plate limiting members 13 with grooves are provided on both sides of the air outlet. In the closed state, the sealing plate 110 is embedded in the groove and fits against the outer side of the air guide plate.

[0080] 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 10 is disposed on the first air outlet 600, and the second air guide plate 12 in the air guide plate structure 10 can close the second air outlet 700 after rotating away from the sealing plate limiting member.

[0081] 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.

[0082] Compared to existing technologies, traditional solutions use multiple independent baffles to close the air outlet, resulting in gaps between the baffles and air leakage. This solution, however, uses a linked sealing structure to ensure a seamless fit between the sealing plate and the air guide plate. Through this technical solution, this application effectively blocks the air leakage path from the air outlet when it is closed, avoiding condensation problems caused by temperature differences due to air leakage.
