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

This significantly improves the closing stability. Attached Figure Description

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In existing technologies, traditional ducted air handling units typically employ a single air outlet design, resulting in a fixed airflow direction after installation. This makes it difficult to meet the diverse needs of different functional areas within the same space. To address the issue of multi-zone air supply, some models adopt a multi-outlet structure. However, multiple independent baffles are required to close unused outlets. These baffles, once closed, have assembly gaps, leading to air leakage. When there is a significant difference between the air conditioner's supply air temperature and the ambient temperature, condensation can easily form at these leaks, potentially damaging the equipment or the indoor environment. For example, in a layout where the living room and dining room are connected, closing the dining room's air outlet can cause cold air leakage through gaps between the baffles, resulting in condensation stains on the walls.

[0047] To address the aforementioned issues, researchers discovered that the core problem of incomplete closure of multi-baffles lies in the lack of a linkage locking mechanism. Traditional baffles rely solely on their own closure, making them prone to slight displacement under wind pressure. By analyzing the mechanical linkage principle, this application proposes designing the free ends of the two air guide plates as a synchronously lockable structure. When the air guide plates close, a sliding locking rod drives the locking tongue to simultaneously insert into the locking slots of both air guide plates, forming a rigid connection. This design concept is inspired by door latch mechanisms, transforming linear motion into multi-point locking to ensure uniform force distribution on the closing surface.

[0048] See Figures 1-3 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 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.

[0049] 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.

[0050] 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.

[0051] Figure 4 for Figure 3An enlarged schematic diagram of K when the first and second air guide plates overlap. In this embodiment, the air guide plate structure includes: a first air guide plate 11, a second air guide plate 12, and a support rod 13. 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. Furthermore, 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 to both sides of the first air outlet 600. Figure 2 As can be seen, both air deflectors are in the open position. Figure 3 In the middle, the two air guide plates are in a closed state and overlap the support rod. The first fixed end 111 of the first air guide plate 11 is fixed to the upper side of the first air outlet 600, and the second fixed end 121 of the second air guide plate 12 is fixed to 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.

[0052] After the free ends of the first air guide plate 11 and the second air guide plate 12 are rotated, they can be attached to the support rod 13. At this time, the first air outlet 600 can be closed. Alternatively, after the free ends of the first air guide plate 11 and the second air guide plate 12 are rotated away from the support rod 13, the first air outlet 600 can be opened.

[0053] In this embodiment, the free ends of both the first air guide plate 11 and the second air guide plate 12 are provided with at least one locking groove with the same guiding direction. See also Figure 5 As shown in the figure, the first air guide plate 11 is used as an example for illustration. The first air guide plate 11 has four locking slots 113. Two rotating shafts 114 are provided on both sides of the fixed end above the first air guide plate 11. The rotating shafts 114 can be engaged in the housing 200 and rotate, allowing the first air guide plate 11 to rotate around the rotating shafts 114. In this embodiment, the structure of the second air guide plate 12 is exactly the same as that of the first air guide plate 11, but it is symmetrically arranged with the first air guide plate 11. For example, the rotating shaft of the second air guide plate 12 is located below it.

[0054] See Figure 4 and Figure 6 As shown, a slidingly connected locking rod 14 is provided on the support rod 13. The locking rod 14 is provided with at least two locking tongues 32 that match the positions of each locking groove on the first air guide plate and the second air guide plate. When the locking rod 14 slides, the locking tongues 32 are inserted into the corresponding locking grooves 113 along the guide direction or slide out of the corresponding locking grooves 113.

[0055] The consistent guiding direction refers to the parallel extension directions of the locking grooves on the two air guide plates. In this embodiment, the guiding direction can be the length direction of the air guide plate. Specifically, this can be achieved using inclined channels at the same angle, ensuring that the locking tongue maintains a synchronized movement trajectory during sliding. The matching relationship between the locking tongue and the locking groove refers to the correspondence between the spatial position of the locking tongue and the opening position of the locking groove. This can be achieved using a staggered arrangement of protrusions, allowing the locking tongue to accurately enter the corresponding groove when the locking rod moves. The overlapping function of the support rod refers to providing a supporting surface for the free end of the air guide plate when closed. This can be achieved using a grooved metal profile, with the groove depth matching the thickness of the air guide plate.

[0056] In practical use, when it is necessary to close the first air outlet 600, the first air guide plate 11 and the second air guide plate 12 rotate around their respective fixed ends until their free ends contact the surface of the support rod 13. At this time, the locking rod 14 can slide along the length of the support rod 13, causing the locking tongue 32 to insert into the locking grooves 113 of the two air guide plates. Since the locking grooves 113 have a consistent guiding angle, the locking tongue 32 exerts the same constraint force on the two air guide plates during movement, forcing the free ends of the two air guide plates to fit tightly against the support rod 13.

[0057] Compared to existing technologies, traditional multi-baffle structures rely on the closing accuracy of individual baffles, lacking mechanical linkage between baffles, and are prone to gaps during vibration or wind pressure changes. This solution synchronously controls the locking state of the two side guide vanes through the linear movement of the locking rod, utilizing a rigid locking tongue to counteract guide vane deformation and form a continuous sealing line on the closed surface. This significantly improves closing stability. The dual guide vanes in this application form a rigid closed structure under the action of the locking tongue, blocking air leakage paths and effectively solving the problems of air leakage and condensation when multiple air outlets are closed.

[0058] In this embodiment, the slot of the latch groove is located on the end face of the free end of the first air guide plate or the second air guide plate; the latch groove has a latch opening on the first side wall corresponding to the position of at least one latch piece; the shape of the latch opening matches the shape of the latch piece, and the opening width is greater than the width of the latch piece; the first side wall is located on the side of the first air guide plate or the free end of the second air guide plate facing the air outlet in the air outlet direction.

[0059] See Figure 5 As shown, the opening of the locking groove 113 is located on the end face of the free end of the first air guide plate 11, that is, the opening direction of the groove is along the direction from the first fixed end 111 of the first air guide plate 11 to the first free end 112. Figure 5 As can be seen, the lower side of the first air guide plate 11 is in contact with the support rod. Here, the lower side refers to the side of the free end of the first air guide plate 11 facing the air outlet 600.

[0060] The upper side wall of the latch groove 113 is the first side wall. A latch opening 115 is provided on the first side wall, which corresponds to the position of at least one latch. The shape of the latch opening 115 matches the shape of the latch 32, and the opening width is greater than the width of the latch 32. Here, the width refers to the distance in the length direction of the first air guide plate. The direction from the first fixed end to the first free end on the first air guide plate is the width direction, and the direction from one side pivot 114 to the other side pivot 114 on the first air guide plate is the length direction.

[0061] In this embodiment, the slot of the latch groove refers to a groove structure provided on the free end face of the air guide plate for accommodating the latch bolt. Specifically, it can be implemented using a rectangular or trapezoidal cross-section groove, the depth of which matches the insertion stroke of the latch bolt, to guide the latch bolt to move in a specific direction. The latch bolt opening refers to a through hole provided on the side wall of the latch groove that corresponds to the shape of the latch bolt. Specifically, it can be formed by stamping or injection molding. The opening width is 0.1 mm to 0.5 mm larger than the width of the latch bolt, for example, 0.3 mm, to allow the latch bolt to smoothly enter the latch groove even if there is a slight deviation during insertion. The first side wall is located on the side of the air guide plate facing the air outlet direction. Specifically, it can be achieved by adjusting the overlap angle when the air guide plate is closed, so that the latch bolt is subjected to pressure in the direction of airflow when inserted into the latch groove, further strengthening the locking state.

[0062] In practical applications, when the first air guide plate 11 rotates to the closed position, the locking groove 113 on the free end face aligns with the locking tongue 32 on the support rod. The locking tongue 32 is inserted into the locking groove 113 along the locking tongue opening 115. The shape of the locking tongue opening 115 can be consistent with the contour of the locking tongue 32 in the length direction, such as using an arc or bevel structure, so that the locking tongue 32 automatically adjusts its position during insertion to avoid jamming.

[0063] In this application, the locking groove 113 on the second air guide plate is consistent with the one on the first air guide plate 11, and the locking tongue opening 115 in the locking groove 113 on both air guide plates is located on the same side of the guiding direction in the corresponding locking groove. Figure 5 As shown, the latch opening 115 is located on the left side of the latch groove.

[0064] In one embodiment of this application, see [link to embodiment]. Figures 4-9 As shown, the support rod 13 is provided with a first overlapping surface 132 that overlaps with the free end of the first air guide plate, a second overlapping surface 133 that overlaps with the free end of the second air guide plate, and a guide rib 134 located between the first overlapping surface and the second overlapping surface; the locking rod 14 is provided with a U-shaped guide groove 41 that slides with the guide rib 134, and the locking tongue 32 is respectively provided on the outer walls of both sides of the U-shaped guide groove 41.

[0065] In this embodiment, the support rod 13 can be a cross-shaped structure, wherein, see... Figure 4 The cross-shaped structure has a first support platform 1321 at the top, a second support platform 1331 at the bottom, and a guide rib 134 on the left. The first overlapping surface 132 can be the side of the first support platform 1321 facing the inside of the shell; the second overlapping surface 133 can be the side of the second support platform 1331 facing the inside of the shell.

[0066] The first overlapping surface 132 refers to the planar structure on the support rod 13 that contacts the free end of the first air guide plate, used to limit the displacement of the first air guide plate in the closed state. The second overlapping surface refers to the planar structure on the support rod that contacts the free end of the second air guide plate, used to fix the position of the second air guide plate when closed. The guide rib 134 refers to the raised strip-shaped structure set between the two overlapping surfaces, which can be manufactured by aluminum alloy extrusion molding process, used to provide a rigid sliding track for the locking rod 14. The U-shaped guide groove 41 refers to the groove structure in the locking rod 14 that cooperates with the guide rib 134, which can be formed by injection molding process, and its inner wall contacts the three sides of the guide rib to constrain the lateral displacement of the locking rod 14. The locking tongue 32 is set on the outer walls on both sides of the U-shaped guide groove to fix the locking tongue in a predetermined position on the outer wall of the groove, which can be fixed by bolt connection or welding to ensure that the movement trajectory of the locking tongue 32 is consistent with the extension direction of the locking rod 14.

[0067] Specifically, when the locking bar slides along the guide rib, the three-sided contact structure of the U-shaped guide groove restricts the horizontal displacement of the locking bar, and the rigid support of the guide rib prevents the locking bar from bending and deforming due to force. When the locking tongue moves with the locking bar, its movement path is strictly limited to the extension direction of the guide rib, ensuring that the movement direction of the locking tongue is aligned with the guide direction of the air guide plate's latch groove. When the locking bar moves to the closed position, the locking tongues on both sides simultaneously insert into the corresponding latch grooves, see [reference]. Figure 13 and 14 As shown, in Figure 13 In the middle, the locking tongue 32 and the locking slot are not locked. Figure 13 In the middle, the locking tongue 32 moves to the right, until... Figure 14 At the indicated position, the locking tongue 32 is locked to the locking groove, preventing the air guide plate from rotating. The contact between the overlapping surface and the free end of the air guide plate creates a double positioning, preventing the air guide plate from shifting under wind pressure.

[0068] To prevent the U-shaped guide groove from detaching from the guide rib, in the embodiments of this application, as follows: Figure 10 As shown, at least one sliding groove 131 is provided on the guide rib 134, and a guide pin 42 is provided on the locking rod 14. The guide pin 42 can pass into the sliding groove 131 and cooperate with the sliding groove 131. Each guide pin 42 is inserted into the corresponding sliding groove 131 and slides in the sliding groove 131.

[0069] The sliding groove 131 refers to the hole structure provided on the surface of the guide rib 134, which is used to limit the movement trajectory of the guide pin. The guide pin 42 refers to the protruding part fixed inside the sliding groove 131, which can be implemented as a cylindrical or rectangular column, and is fitted with the sliding groove 131.

[0070] Specifically, when the locking rod 14 is subjected to a driving force, the guide pin 42 slides along a predetermined path within the sliding groove 131, forcing the movement direction of the locking rod 14 to be mechanically limited. The side wall of the sliding groove 131 and the contact surface of the guide pin 42 form a sliding constraint, eliminating the possibility of the locking rod 14 deviating.

[0071] See Figure 6 , Figure 11 and Figure 12 As shown, this application further proposes to install a drive end on the locking bar ( Figure 6 The right end is the drive end. A rack 33 is provided on the drive end. A locking rod drive motor 34 is provided in the air conditioner 100 at the position corresponding to the drive end. The rotating shaft of the locking rod drive motor 34 meshes with the rack 33 through a gear 35. The rack 33 drives the locking rod 14 to slide back and forth on the guide rib 134.

[0072] The drive end refers to the part connecting the end of the locking lever to the transmission mechanism. This can be implemented using a metal component with a rack and pinion, converting rotary motion into linear motion. The locking lever drive motor is a miniature stepper motor with a gear mounted on its shaft. This can be implemented using a DC motor with a gearbox, providing precise and controllable driving force. Gear and rack meshing refers to the continuous contact between the gear teeth and the rack's tooth grooves. This can be implemented using an involute gear pair with a module of 0.5-1.0, converting the motor's rotary motion into the linear displacement of the locking lever.

[0073] See Figure 12 As shown, the rotating shaft 114 at the end of the first air guide plate 11 can be connected to the first drive motor 110. The first drive motor 110 can drive the rotating shaft 114, thereby driving the first air guide plate 11 to rotate. Similarly, the rotating shaft at the end of the second air guide plate 12 can be connected to the second drive motor 120. The second drive motor 120 can drive the rotating shaft, thereby driving the second air guide plate 12 to rotate.

[0074] To further improve sealing, in this embodiment, at least one flexible sealing gasket is provided on the first overlapping surface 132 or the second overlapping surface 133 of the support rod 13. See also Figure 4As shown, a first flexible sealing gasket 21 is provided on the first overlapping surface 132. When the free end of the first air guide plate 11 overlaps with the first overlapping surface 132, it can press on the first flexible sealing gasket 21 to seal the gap between the first air guide plate 11 and the support rod. A second flexible sealing gasket 22 is provided on the second overlapping surface 133. When the free end of the second air guide plate 12 overlaps with the second overlapping surface 133, it can press on the second flexible sealing gasket 22 to seal the gap between the second air guide plate 12 and the support rod.

[0075] The first overlapping surface refers to the planar structure on the support rod that receives the free end of the first air guide plate. Its shape matches the contact area of ​​the free end of the air guide plate, achieving positioning of the air guide plate when closed through planar contact. The second overlapping surface refers to the planar structure on the support rod that receives the free end of the second air guide plate, and its function is the same as the first overlapping surface. The flexible sealing gasket refers to a strip-shaped component made of elastic material, specifically rubber, silicone, or foam material. Its thickness can be compressed and deformed to fill the gap between the contact surfaces.

[0076] Specifically, when the air guide plate rotates to the closed position, its free end contacts the overlapping surface of the support rod, and the flexible sealing gasket undergoes compression deformation under the pressure of the air guide plate. The compressed sealing gasket completely fills the assembly gap between the air guide plate and the overlapping surface, forming a continuous sealing interface. Thus, even if there are manufacturing tolerances or component deformation due to long-term use, the adaptive deformation of the elastic material can still maintain the sealing effect and prevent air leakage from the overlapping surface.

[0077] 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 plate structure 10 is provided at the first air outlet 600.

[0078] In this embodiment, the air guide plate structure includes: a first air guide plate 11, a second air guide plate 12, and a support rod 13. 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. Furthermore, 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 to both sides of the first air outlet 600. Figure 2As 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.

[0079] After the free ends of the first air guide plate 11 and the second air guide plate 12 are rotated, they can be attached to the support rod 13. At this time, the first air outlet 600 can be closed. Alternatively, after the free ends of the first air guide plate 11 and the second air guide plate 12 are rotated away from the support rod 13, the first air outlet 600 can be opened.

[0080] In this embodiment, the free ends of both the first air guide plate 11 and the second air guide plate 12 are provided with at least one locking groove with the same guiding direction. See also Figure 5 As shown in the figure, the first air guide plate 11 is used as an example for illustration. The first air guide plate 11 has four locking slots 113. Two rotating shafts 114 are provided on both sides of the fixed end above the first air guide plate 11. The rotating shafts 114 can be engaged in the housing 200 and rotate, allowing the first air guide plate 11 to rotate around the rotating shafts 114. In this embodiment, the structure of the second air guide plate 12 is exactly the same as that of the first air guide plate 11, but it is symmetrically arranged with the first air guide plate 11. For example, the rotating shaft of the second air guide plate 12 is located below it.

[0081] See Figure 4 and Figure 6 As shown, a slidingly connected locking rod 14 is provided on the support rod 13. The locking rod 14 is provided with at least two locking tongues 32 that match the positions of each locking groove on the first air guide plate and the second air guide plate. When the locking rod 14 slides, the locking tongues 32 are inserted into the corresponding locking grooves 113 along the guide direction or slide out of the corresponding locking grooves 113.

[0082] In one embodiment of this application, such as Figure 2 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 rotation.
