In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0075] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0076] The air guide plate assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0077] like Figures 1-19 As shown, the air guide plate assembly 100 according to an embodiment of the present utility model includes a first air guide plate 3, a first rod 1, and a second rod 2.

[0078] Specifically, such as Figure 1 As shown, combined Figure 2 and Figure 3 The air guide plate assembly 100 is used in the air conditioner 200, which includes a housing 7. The housing 7 has an air outlet 71 that extends horizontally. The housing 7 forms the overall appearance of the air conditioner 200. An air duct 72 is formed inside the housing 7, and the air outlet 71 communicates with the air duct 72. The top of the housing 7 may also have an air inlet 73 that communicates with the air duct 72 to allow airflow to enter the air duct 72 through the air inlet 73.

[0079] like Figures 2-6 or Figure 10-15 As shown in the example, the housing 7 also includes a heat exchanger 8, a cross-flow fan 9, and louvers 10. In the airflow direction within the duct 72, the heat exchanger 8 is upstream of the cross-flow fan 9, and the louvers 10 are downstream of the cross-flow fan 9, near the air outlet 71. The heat exchanger 8 is used for heat exchange with the airflow flowing over its surface. The cross-flow fan 9 drives the airflow from the air inlet 73 to the air outlet 71. The first guide plate 3 and the second guide plate 6 can adjust the airflow angle vertically at the air outlet 71, while the louvers 10 can adjust the airflow angle horizontally within the duct 72.

[0080] During the specific operation of the air conditioner 200, driven by the cross-flow fan 9, outside air enters the air duct 72 inside the casing 7 from the air inlet 73. After heat exchange by the heat exchanger 8, the heat-exchanged air flows out of the air conditioner 200 from the air outlet 71 under the guidance of the louvers 10, the second air guide plate 6 and the first air guide plate 3, so as to ensure the cooling, heating and air supply functions of the air conditioner 200.

[0081] The first air guide plate 3 is used to open or close the air outlet 71. When the first air guide plate 3 opens the air outlet 71, the upper end of the first air guide plate 3 flips downward. One end of the first rod 1 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air guide plate 3. One end of the second rod 2 is rotatably connected to the housing 7, and the other end is rotatably connected to the first air guide plate 3. The second rod 2 is located above the first rod 1 and is spaced apart from the first rod 1 in the vertical direction. The upper side of the second rod 2 has a recessed relief groove 11.

[0082] Specifically, when the first air guide plate 3 closes the air outlet 71, the end of the first air guide plate 3 near the upper side wall of the air outlet 71 is the upper end of the first air guide plate 3, and the end of the first air guide plate 3 near the lower side wall of the air outlet 71 is the lower end of the first air guide plate 3. The second rod 2 being located above the first rod 1 can be understood as: the end of the second rod 2 rotatably connected to the housing 7 is located above the end of the first rod 1 rotatably connected to the housing 7. The first rod 1 being spaced apart in the vertical direction can be understood as: the end of the second rod 2 rotatably connected to the housing 7 is spaced apart from the end of the first rod 1 rotatably connected to the housing 7 in the vertical direction.

[0083] It is understandable that the housing 7, the first rod 1, the second rod 2, and the first air guide plate 3 can form a four-bar linkage mechanism. The first air guide plate 3 is the driven component in the four-bar linkage mechanism. The connection point where one end of the first rod 1 and the second rod 2 is rotatably connected to the housing 7 can serve as a fulcrum. Through the rotation of the first rod 1 and the second rod 2, the motion is transmitted to the first air guide plate 3, so that the motion of the first air guide plate 3 is no longer a simple linear or circular motion, but rather it rotates according to a predetermined trajectory to complete the action of opening or closing the air outlet 71. The design structure of the above four-bar linkage mechanism is simple and low in cost, and it can make the motion trajectory of the first air guide plate 3 more precise and controllable.

[0084] Meanwhile, the two ends of the first rod 1 and the second rod 2 are rotatably connected to the housing 7 and the first air guide plate 3, respectively, which can disperse the stress and impact during the movement process, making the first air guide plate 3 more stable when opening or closing the air outlet 71, thereby reducing vibration and noise and enhancing the reliability and stability of the air guide plate assembly 100.

[0085] Rotating the first rod 1 and the second rod 2 at different angles can drive the first air guide plate 3 to complete different angle flips and different position movements, which can increase the diversity of the air guiding mode of the first air guide plate 3. Without increasing the size of the air conditioner 200 or increasing the cost, different air supply states of the air conditioner 200 can be realized, improving the richness of the air conditioning air output effect, meeting the diverse needs of users, and thus improving the user's comfort and experience.

[0086] Furthermore, the upper side of the second rod 2 has a recessed relief groove 11, which can effectively avoid the end of the first air guide plate 3 that is close to the second rod 2, so that the transmission range of the four-bar linkage is larger in a limited space, thereby effectively increasing the rotation angle range of the first air guide plate 3, and thus increasing the air supply range of the air conditioner 200 in the vertical direction.

[0087] For example, such as Figure 6 or Figure 14As shown in the example, the air conditioner 200 is in a cooling state and can achieve upward airflow. At this time, the upper end of the first air guide plate 3 is flipped downward to open the air outlet 71. The first air guide plate 3 is inclined in the direction away from the air outlet 71 from bottom to top, and the air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. At this time, the air inlet end of the first air guide plate 3 can extend into the recessed relief groove 11 in the second rod 2. The recessed relief groove 11 of the second rod 2 can make the downward tilt angle of the air inlet end of the first air guide plate 3 larger, and the upward tilt angle of the air outlet end of the first air guide plate 3 larger. This can increase the upward flow angle of the airflow in the vertical direction, thereby expanding the air supply range of the air conditioner 200 in the vertical direction, and also helping to achieve long-distance air supply, thereby helping to improve the uniformity of indoor temperature.

[0088] In addition, during the specific implementation process, the length and angle of the first rod 1 and the second rod 2 can be adjusted as needed to achieve different angles of rotation and different positions of the first air guide plate 3, thereby achieving different air guiding effects.

[0089] According to the embodiment of this utility model, the air guide plate assembly 100 forms a four-bar linkage by rotatably connecting the two ends of the first rod 1 and the second rod 2, which are spaced apart in the vertical direction, to the housing 7 and the first air guide plate 3, respectively. This allows the first air guide plate 3 to rotate at different angles and move to different positions, thereby achieving different air supply states of the air conditioner 200. Simultaneously, the upper side of the second rod 2 has a recessed clearance groove 11, which effectively avoids the end of the first air guide plate 3 near the second rod 2. This allows for a larger transmission range of the four-bar linkage within a limited space, effectively increasing the rotation angle range of the first air guide plate 3, i.e., increasing the vertical air supply range of the air conditioner 200, thus meeting diverse user needs and improving user comfort and experience.

[0090] In some embodiments of this utility model, the second rod 2 is a straight rod, and the upper surface of the second rod 2 is recessed downward to form a recessed relief groove 11. Machining the recessed relief groove 11 on the straight rod can effectively reduce the machining difficulty, facilitate production, and improve production efficiency.

[0091] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, the second rod 2 is a curved rod, and the lower side of the second rod 2 has a protrusion 22 at least corresponding to the position of the recessed relief groove 11. By setting the protrusion 22, the structural strength of the second rod 2 can be effectively enhanced, especially the structural strength of the second rod 2 at the location where the recessed relief groove 11 is provided. This can prevent the second rod 2 from bending or breaking at the location where the recessed relief groove 11 is provided, thereby enhancing the stability and reliability of the four-bar structure formed by the air guide plate assembly 100.

[0092] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, when the first air guide plate 3 closes the air outlet 71, both the first rod 1 and the second rod 2 are connected to the upper end of the first air guide plate 3. The recessed clearance groove 11 is located at the end of the second rod 2 near the first air guide plate 3 along its length. The connection of the first rod 1 and the second rod 2 to the upper end of the first air guide plate 3 can be understood as: relative to the lower end of the first air guide plate 3, the first rod 1 and the second rod 2 are connected to a position closer to the upper end of the first air guide plate 3. The upper end of the first air guide plate 3 is the end near the upper edge of the air outlet 71 when the first air guide plate 3 closes the air outlet 71. This ensures that the rotation axis of the first rod 1 and the first air guide plate 3, and the rotation axis of the second rod 2 and the first air guide plate 3, are located at the upper end of the first air guide plate 3. This facilitates the first rod 1 and the second rod 2 to rotate the upper end of the first air guide plate 3 downwards to open the air outlet 71. The structural design is reasonable and can guarantee the function of the first air guide plate 3 in opening or closing the air outlet 71, thereby ensuring the air supply function of the air conditioner 200.

[0093] The first rod 1 and the second rod 2 can apply force to the upper end of the first air guide plate 3, causing the first air guide plate 3 to tilt. This allows the lower end of the first air guide plate 3 to open the air outlet 71 first downward and then upward, resulting in a reasonable structural design. At the same time, the recessed clearance groove 11 is set at the end of the second rod 2 near the first air guide plate 3, which facilitates the upper end of the first air guide plate 3 to smoothly extend into the recessed clearance groove 11 when it opens the air outlet 71. This effectively increases the rotation angle range of the first air guide plate 3, resulting in a reasonable structural arrangement.

[0094] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, the connection point between the second rod 2 and the first air guide plate 3 is located between the upper end of the first air guide plate 3 and the connection point between the first rod 1 and the first air guide plate 3. It can be understood that the rotatable connection point between the second rod 2 and the first air guide plate 3 is located above and spaced apart from the rotatable connection point between the first rod 1 and the first air guide plate 3. This avoids the first rod 1 and the second rod 2 from crossing and colliding and interfering during movement, thus forming a four-bar linkage mechanism with the first rod 1, the second rod 2, the housing 7, and the first air guide plate 3. This mechanism drives the upper end of the first air guide plate 3 to flip downwards and open the air outlet 71, resulting in a reasonable structural design.

[0095] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19As shown, during the opening process of the first air guide plate 3 from the closed position, the lower end of the first air guide plate 3 first descends and then rises in the vertical direction. When the first air guide plate 3 opens the air outlet 71, the end of the first rod 1 connected to the first air guide plate 3 and the end of the second rod 2 connected to the first air guide plate 3 move downwards, causing the first air guide plate 3 to move downwards as a whole. The rotation angle and rotation speed of the second rod 2 are greater than those of the first rod 1. As the second rod 2 continues to rotate, the upper end of the first air guide plate 3 continues to move downwards or diagonally downwards under the support of the first rod 1, while the lower end of the first air guide plate 3 moves upwards or diagonally upwards, thereby opening the air outlet 71. This ensures stable coordination between the first rod 1 and the second rod 2, as well as the stability of the process of the first air guide plate 3 opening the air outlet 71.

[0096] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, at least one end of the first rod 1 along its length has a first rotating shaft 23. The first rotating shaft 23 is rotatably connected to the first air guide plate 3 and / or the housing 7. The first rotating shaft 23 is provided with a first groove 231. The first groove 231 passes through the first rotating shaft 23 along the radial direction of the first rotating shaft 23 and is open at one end away from the first rod 1.

[0097] It is understandable that the first air guide plate 3 and / or the housing 7 are provided with a first rotating hole, and the first rotating shaft 23 passes through the first rotating hole, thereby realizing the rotatable connection between the first rotating shaft 23 and the first air guide plate 3 and / or the housing 7. The structure is simple, easy to implement, and low in cost. By providing a first groove 231 on the first rotating shaft 23, the first rotating shaft 23 has a certain deformation capability in the radial direction, which makes it easier to insert the first rotating shaft 23 into the first rotating hole, reducing assembly difficulty and thus improving assembly efficiency.

[0098] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, the end of the second rod 2 connected to the first air guide plate 3 in the length direction has a second rotating shaft. The second rotating shaft is rotatably connected to the first air guide plate 3. The second rotating shaft is provided with a second groove. The second groove passes through the second rotating shaft in the radial direction and is open at the end away from the second rod 2.

[0099] Understandably, the first air guide plate 3 has a second rotating hole, through which the second rotating shaft passes, thus enabling a rotatable connection between the second rotating shaft and the first air guide plate 3. This structure is simple, easy to implement, and low in cost. By providing a second groove on the second rotating shaft, the second rotating shaft has a certain deformation capability in the radial direction, making it easier to insert the second rotating shaft into the second rotating hole, reducing assembly difficulty, and thus improving assembly efficiency.

[0100] In some embodiments of this utility model, such as Figures 2-6 and Figures 10-15 As shown, when the first air guide plate 3 closes the air outlet 71, the first rod 1 and the second rod 2 are rotatably connected to the inner surface of the first air guide plate 3. The inner surface of the first air guide plate 3 is the surface facing the air outlet 71 when the first air guide plate 3 closes the air outlet 71. This can shield the first rod 1 and the second rod 2, preventing them from being exposed and thus improving the aesthetics of the air conditioner 200. At the same time, it makes it easier for the first rod 1 and the second rod 2 to rotate the first air guide plate 3, ensuring the stability of the air guide plate assembly 100. It should be noted that when the first air guide plate 3 closes the air outlet 71, the side of the first air guide plate 3 facing the inside of the housing 7 is the inner surface, and the side of the first air guide plate 3 away from the inside of the housing 7 is the outer surface.

[0101] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, the first air guide plate 3 includes a first plate body 32, a first mounting protrusion 33 and a second mounting protrusion 34. When the air outlet 71 of the first air guide plate 3 is closed, the first mounting protrusion 33 and the second mounting protrusion 34 are located inside the first plate body 32. The first rod 1 is rotatably connected to the first mounting protrusion 33, and the second rod 2 is rotatably connected to the second mounting protrusion 34.

[0102] Understandably, the first mounting protrusion 33 has a first rotating hole, and the second mounting protrusion 34 has a second rotating hole, allowing the first rod 1 to pass through the first rotating hole to achieve a rotatable connection between the first rod 1 and the first plate 32 body, and the second rod 2 to pass through the second rotating hole, thereby achieving a rotatable connection between the second rod 2 and the first plate 32 body. This design is simple, easy to implement, and low in cost. By setting the first mounting protrusion 33 and the second mounting protrusion 34, the assembly difficulty of the first rod 1 and the second rod 2 with the first air guide plate 3 can be reduced, thereby improving assembly efficiency.

[0103] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, the rotation axis of the first rod 1 and the housing 7 is located on the lower side of the air outlet 71 in the width direction, and the rotation axis of the second rod 2 and the housing 7 is spaced apart from both ends of the air outlet 71 in the width direction. This facilitates the placement of components such as the first drive assembly 4 at the end of the second rod 2 opposite to the first air guide plate 3, resulting in a reasonable spatial arrangement and effective utilization of the internal space of the housing 7. Simultaneously, it avoids collisions or interference between the first rod 1 and the second rod 2 during rotation, ensuring the transmission of the four-bar linkage, thereby guaranteeing the performance of the air guide plate assembly 100 and realizing the air supply function of the air conditioner 200.

[0104] like Figure 2 and Figure 10As shown in the example, when the first air guide plate 3 closes the air outlet 71, the rotation axis of the first rod 1 and the first air guide plate 3, and the rotation axis of the second rod 2 and the first air guide plate 3, are located at the upper end of the first air guide plate 3, that is, at the end of the first air guide plate 3 that is away from the rotation axis of the first rod 1 and the housing 7. When the air conditioner 200 blows air, the rotation of the first rod 1 and the second rod 2 can drive the first air guide plate 3 to flip upward. When the air outlet 71 is closed, the lower end of the first air guide plate 3 moves away from the air outlet 71, and the upper end of the first air guide plate 3 moves downward to open the air outlet 71, thereby realizing the air supply function of the air conditioner 200.

[0105] In some embodiments, as Figure 2 and Figure 10 As shown, when the first air guide plate 3 closes the air outlet 71, the rotation axis of the second rod 2 and the housing 7, and the rotation axis of the second rod 2 and the first air guide plate 3 are respectively located on the upper side of the rotation axis of the first rod 1 and the housing 7, and the rotation axis of the first rod 1 and the first air guide plate 3 along the width direction of the air outlet 71. This facilitates the transmission of the four-bar linkage formed by the housing 7, the first rod 1, the second rod 2, and the first air guide plate 3, and can avoid collisions or interference between the first rod 1 and the second rod 2 during rotation, ensuring that the first air guide plate 3 can be flipped and moved under the drive of the first rod 1 and the second rod 2, so as to ensure the performance of the air guide plate assembly 100 and realize the air supply function of the air conditioner 200.

[0106] In some embodiments of this utility model, such as Figure 7 , Figure 8 , Figure 16 and Figure 17 As shown, the first rod 1 and the second rod 2 are spaced apart along the length of the air outlet 71. This facilitates the transmission of the four-bar linkage formed by the housing 7, the first rod 1, the second rod 2, and the first air guide plate 3, and avoids collisions or interference between the first rod 1 and the second rod 2 during rotation. This ensures that the first air guide plate 3 can rotate and move under the drive of the first rod 1 and the second rod 2, thereby ensuring the performance of the air guide plate assembly 100 and realizing the air supply function of the air conditioner 200.

[0107] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, the first rod 1 consists of multiple rods spaced apart along the length of the first air guide plate 3, and the second rod 2 consists of multiple rods spaced apart along the length of the first air guide plate 3. Thus, along the length of the first air guide plate 3, the housing 7, the first rod 1, the second rod 2, and the first air guide plate 3 can form multiple four-bar linkages. This allows the force on the first air guide plate 3 to be distributed and more evenly distributed during the rotation of the first rod 1 and the second rod 2, which in turn causes the first air guide plate 3 to flip, thus improving the reliability and stability of the air guide plate assembly 100.

[0108] In some embodiments, the rotation of the first rod 1 and the second rod 2 can drive the first air guide plate 3 to close the air outlet 71 and guide the airflow out of the air outlet 71, for example, as Figures 3-6 As shown in the example, when the user uses the air conditioner 200, the rotation of the first lever 1 and the second lever 2 can cause the upper end of the first air guide plate 3 to flip downwards to open the air outlet 71. Airflow can then smoothly pass through the air duct 72 and be guided by the first air guide plate 3 to be blown out from the air outlet 71, thus meeting the user's air supply needs. For example, as... Figure 1-Figure 2 As shown in the example, when the user does not need to use the air conditioner 200, the air conditioner 200 stops blowing air, and the first lever 1 and the second lever 2 can move the first air guide plate 3 to the position where the air outlet 71 is closed. At this time, the first air guide plate 3 and the housing 7 constitute the complete appearance of the air conditioner 200, thereby improving the aesthetics of the air conditioner 200, and also serving a dust prevention function. The air guide plate assembly 100 can ensure the basic functions of the air conditioner 200 and improve the practicality of the air conditioner 200.

[0109] It should be noted that the air outlet 71 can extend along the length of the housing 7 and be elongated. The elongated air outlet 71 can increase the air volume and air delivery range. At this time, the first air guide plate 3 extends along the length of the air outlet 71 and is elongated, so that the first air guide plate 3 can be adapted to the air outlet 71, making it easy for the first air guide plate 3 to close the air outlet 71.

[0110] Simultaneously, the rotation axis of the first rod 1 and the rotation axis of the second rod 2 can extend along the length of the air outlet 71, facilitating the closing of the air outlet 71 by the first air guide plate 3, or enabling the first air guide plate 3 to guide airflow in the width direction of the air outlet 71. Figure 1 and Figure 9 As shown, the air conditioner 200 is a wall-mounted unit, the air outlet 71 extends along the left and right directions of the air conditioner 200, and the first air guide plate 3 can guide air in the up and down directions.

[0111] In some embodiments of this utility model, such as Figure 7 , Figure 8 , Figure 16 and Figure 17As shown, the air guide plate assembly 100 also includes a first drive assembly 4, which is mounted on the housing 7. The first drive assembly 4 is located at at least one of the ends of the first rod 1 and the second rod 2 that are opposite to the first air guide plate 3, and is connected to the first drive assembly 4 for driving the first rod 1 or the second rod 2 to rotate. For example, the first drive assembly 4 is located at the end of the second rod 2 that is opposite to the first air guide plate 3, for driving the second rod 2 to rotate. In this case, the second rod 2 is the driving rod, and the first rod 1 is the driven rod. The first drive assembly 4 can increase the torque to drive the second rod 2 to rotate, thereby driving the first rod 1 to rotate. The first rod 1 and the second rod 2 drive the first air guide plate 3 to rotate and move at a certain angle, thereby achieving different air supply states of the air conditioner 200.

[0112] Of course, the first drive assembly 4 can be provided only at the end of the first rod 1 that is away from the first air guide plate 3 to drive the first rod 1 to rotate, or the first drive assembly 4 can be provided at the ends of the first rod 1 and the second rod 2 that are away from the first air guide plate 3 to drive the first rod 1 and the second rod 2 to rotate respectively.

[0113] In some embodiments, the first drive assembly 4 includes a first drive motor 41, which is mounted on the housing 7. The output shaft of the first drive motor 41 is connected to either the end of the first rod 1 facing away from the first air guide plate 3 or the end of the second rod 2 facing away from the first air guide plate 3. For example, the first drive motor 41 can be connected only to the end of the second rod 2 facing away from the first air guide plate 3, and a first shaft hole 21 is provided for the output shaft of the first drive motor 41 to pass through. This allows the first drive motor 41 to connect with the second rod 2 through the cooperation of its output shaft and the first shaft hole 21, thereby providing power for the rotation of the second rod 2. The structure is reasonably designed. The first drive motor 41 drives the second rod 2 to rotate through its output shaft, thereby causing the first rod 1 to rotate, which in turn causes the first air guide plate 3 to rotate and move at a certain angle. This ensures the performance of the air guide plate assembly 100 and enables different air supply states of the air conditioner 200.

[0114] Of course, the first drive motor 41 can be set only at the end of the first rod 1 away from the first air guide plate 3 to drive the first rod 1 to rotate, or the first drive motor 41 can be set at the ends of the first rod 1 and the second rod 2 away from the first air guide plate 3 to drive the first rod 1 and the second rod 2 to rotate respectively.

[0115] In some embodiments, as Figure 7 , Figure 8 , Figure 16 and Figure 17As shown, the first drive assembly 4 includes a first drive motor 41 and a gear mechanism 42. The first drive motor 41 is mounted on the housing 7. The input end of the gear mechanism 42 is connected to the output shaft of the first drive motor 41, and the output end of the gear mechanism 42 is connected to either the end of the first rod 1 facing away from the first air guide plate 3 or the end of the second rod 2 facing away from the first air guide plate 3. For example, the gear mechanism 42 may have a meshing drive gear and a driven gear. The drive gear is located at the input end of the gear mechanism 42 and is connected to the output shaft of the first drive motor 41, while the driven gear is located at the output end of the gear mechanism 42 and is connected to either the end of the first rod 1 facing away from the first air guide plate 3 or the end of the second rod 2 facing away from the first air guide plate 3.

[0116] When the first drive motor 41 rotates, it transmits power through the drive gear, driving the driven gear connected to the first rod 1 or the second rod 2 to rotate, thereby driving the first rod 1 or the second rod 2 to rotate, so as to realize the flipping and movement of the first air guide plate 3. This can ensure the performance of the air guide plate assembly 100 and realize different air supply states of the air conditioner 200. The meshing of the gear mechanism 42 is stable and accurate, which is conducive to increasing the torque and improving the stability and accuracy of the transmission.

[0117] In some embodiments of this utility model, such as Figures 1-8 As shown, the air guide plate assembly 100 also includes a second air guide plate 6, which is rotatably disposed at the air outlet 71. When the air conditioner 200 is in the off state, the first air guide plate 3 closes the air outlet 71, and the second air guide plate 6 is located outside the first air guide plate 3 and is stacked with the first air guide plate 3. The second air guide plate 6 can change the air guiding direction by rotating, guiding the airflow from the air outlet 71 of the air conditioner 200 in different directions. The first air guide plate 3 and the second air guide plate 6 work together to achieve the function and effect of air outlet at different angles of the air conditioner 200, so as to realize different air supply states of the air conditioner 200, improve the richness of the air outlet effect, meet the diverse needs of users, and thus improve the user's comfort and experience. The air guide plate assembly 100 can ensure the basic functions of the air conditioner 200 and improve the practicality of the air conditioner 200.

[0118] Among them. For example, Figure 1 and Figure 2As shown in the example, when the air conditioner 200 is in the off state, it stops airflow. The first air guide plate 3 flips to the position where the air outlet 71 is closed, and the second air guide plate 6 also rotates to the position where the air outlet 71 is closed. The second air guide plate 6 is located outside the first air guide plate 3 and is stacked with it. At this time, the first air guide plate 3 and the second air guide plate 6 together close the air outlet 71, and together with the housing 7, they form the complete appearance of the air conditioner 200, which can improve the aesthetics of the air conditioner 200. At the same time, the stacked first air guide plate 3 and the second air guide plate 6 can form a tighter sealing structure, which can improve the dust prevention effect and thus improve the cleanliness of the inside of the air conditioner 200.

[0119] When the air conditioner 200 is off, the first air guide plate 3 closes the upper part of the air outlet 71, and the second air guide plate 6 closes the lower part of the air outlet 71. The upper end of the second air guide plate 6 and the lower end of the first air guide plate 3 are stacked together. The first air guide plate 3 and the second air guide plate 6 cooperate with each other to completely block the air outlet 71.

[0120] In some embodiments of this utility model, such as Figures 9-17 As shown, the air guide plate assembly 100 also includes a second air guide plate 6, which is rotatably disposed at the air outlet 71. When the air conditioner 200 is in the off state, the first air guide plate 3 closes the air outlet 71, and the second air guide plate 6 is located inside the first air guide plate 3 and inside the air outlet 71. The width of the second air guide plate 6 is smaller than the width of the first air guide plate 3. The second air guide plate 6 can change the airflow direction by rotating, directing the airflow in the air duct 72 of the air conditioner 200 in different directions at the air outlet 71. The first air guide plate 3 and the second air guide plate 6 work together to achieve the function and effect of air outlets at different angles in the air conditioner 200, thereby achieving different air supply states, increasing the richness of the air conditioning's airflow effect, meeting diverse user needs, and ultimately improving user comfort and experience.

[0121] In addition, such as Figure 9 and Figure 10 As shown in the example, when the user does not need to use the air conditioner 200, the air conditioner 200 stops airflow. The first air guide plate 3 can be flipped to the position where the air outlet 71 is closed, and the second air guide plate 6 rotates to the inside of the first air guide plate 3 and is located inside the air outlet 71. At this time, the first air guide plate 3 and the housing 7 constitute the complete appearance of the air conditioner 200, thereby improving the aesthetics of the air conditioner 200, and also serving a dustproof function. The air guide plate assembly 100 can ensure the basic functions of the air conditioner 200 and improve the practicality of the air conditioner 200.

[0122] In some embodiments of this utility model, such as Figure 4As shown, when the air conditioner 200 is off, the second air guide plate 6 is located outside the first air guide plate 3 and is stacked with the first air guide plate 3. When the air conditioner 200 is in heating mode, the first air guide plate 3 opens the air outlet 71 from the bottom. The first air guide plate 3 is generally vertically arranged, and the second air guide plate 6 is located outside the air outlet 71 and below the air outlet 71.

[0123] Understandably, the housing 7 contains an air duct 72 connected to the air outlet 71. In heating mode, the second air guide plate 6 rotates downwards around the rotation axis located at the lower end of the air outlet 71 until it is below the air outlet 71 and tilts in a direction away from the air outlet 71 from top to bottom. At this time, the second air guide plate 6 fully opens the air outlet 71 and does not interfere with the hot airflow flowing out of the air outlet 71. At the same time, the air inlet end of the first air guide plate 3 is located near the upper end of the air outlet 71, and the first air guide plate 3 is generally vertically set. Thus, the inner surface of the first air guide plate 3 can guide the hot airflow flowing out of the air outlet 71 downwards, causing the hot airflow to blow downwards. Blowing the hot air downwards in the room is beneficial for the expansion and rise of hot air and the sinking of cold air, accelerating the alternation of hot and cold air and air circulation in the room, accelerating the indoor temperature rise, and thus improving the heating effect of the air conditioner 200.

[0124] In some embodiments of this utility model, such as Figure 5 As shown, when the air conditioner 200 is off, the second air guide plate 6 is located outside the first air guide plate 3 and is stacked with the first air guide plate 3. The air conditioner 200 has a cooling downward sweeping state. In the cooling state, the first air guide plate 3 opens the air outlet 71. The air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. The first air guide plate 3 is inclined in the direction away from the air outlet 71 from top to bottom. The second air guide plate 6 is located below the air outlet 71.

[0125] Understandably, in the cooling downward sweeping state, the second air guide plate 6 rotates downward around the rotation axis located at the lower end of the air outlet 71 until it is below the air outlet 71 and tilts downward in the direction away from the air outlet 71. This allows the air outlet 71 to be fully opened, avoiding interference with the airflow flowing out of the air outlet 71. The second air guide plate 6, located below the air outlet 71, also reduces the air resistance within the air duct 72, ensuring the airflow volume from the air outlet 71. Meanwhile, the air inlet end of the first air guide plate 3 and the two ends of the air outlet 71 are spaced apart in the width direction. In the vertical direction, the air outlet end of the first air guide plate 3 is located below or diagonally below the air inlet end of the first air guide plate 3. Thus, the first air guide plate 3 can form an extension of the air duct 72, so that the flow direction of the airflow from the air outlet 71 is roughly the same as the extension direction of the air duct 72. The airflow can flow smoothly from the air outlet 71, ensuring the air volume of the air conditioner 200, thereby achieving good circulation of cold air in the room and improving the cooling efficiency of the air conditioner 200.

[0126] In some embodiments of this utility model, such as Figure 6 As shown, when the air conditioner 200 is off, the second air guide plate 6 is located outside the first air guide plate 3 and is stacked with the first air guide plate 3. The air conditioner 200 has a cooling upward sweeping state. In the cooling upward sweeping state, the first air guide plate 3 opens the air outlet 71. The air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. The first air guide plate 3 is inclined towards the air outlet 71 in the direction from top to bottom. The second air guide plate 6 is located below the air outlet 71.

[0127] Understandably, in the cooling upward sweep mode, the second air guide plate 6 rotates downward around the rotation axis located at the lower end of the air outlet 71 until it is below the air outlet 71 and tilts downward in the direction away from the air outlet 71. This fully opens the air outlet 71, avoiding interference with the airflow flowing out of the air outlet 71. The second air guide plate 6, located below the air outlet 71, also reduces the wind resistance within the air duct 72, ensuring the airflow volume from the air outlet 71. Simultaneously, the air inlet end of the first air guide plate 3 is spaced apart from both ends of the air outlet 71 in the width direction. In the vertical direction, the air outlet end of the first air guide plate 3 is located above or diagonally above the air inlet end of the first air guide plate 3. This guides the airflow diagonally upward, thereby expanding the air supply range and angle of the air conditioner 200 in the vertical direction and enabling long-distance air supply, thus improving the uniformity of indoor temperature.

[0128] In some embodiments, when the air conditioner 200 is in cooling mode, the air inlet end of the first air guide plate 3 and the two ends of the air outlet 71 are spaced apart in the width direction. The air outlet end of the first air guide plate 3 can also swing back and forth between two positions located above and below the air inlet end of the first air guide plate 3, so that the first air guide plate 3 can sweep air back and forth in the vertical direction. At this time, both sides of the first air guide plate 3 in the thickness direction are guided by air, and the airflow can flow out from the air outlet 71 at different angles in the vertical direction, ensuring the vertical sweeping and air delivery state of the air conditioner 200, thereby enhancing the circulation effect of cold air in the room and improving the cooling efficiency of the air conditioner 200.

[0129] In some embodiments of this utility model, such as Figure 12 As shown, when the air conditioner 200 is off, the second air guide plate 6 is located inside the first air guide plate 3 and inside the air outlet 71. When the air conditioner 200 is in heating mode, the first air guide plate 3 opens the air outlet 71 from the bottom. The first air guide plate 3 is generally vertically arranged, and the second air guide plate 6 is located on the upper side inside the air outlet 71.

[0130] Understandably, an air duct 72 communicating with the air outlet 71 is formed inside the housing 7. In the heating state, the second air guide plate 6 rotates upward around the rotation axis located at the lower end of the air outlet 71 to the upper side inside the air outlet 71, so that the air inlet end of the second air guide plate 6 is joined or close to the upper side wall of the air duct 72 and tilted towards the outside of the air outlet 71 in the top-to-bottom direction. At the same time, in the vertical direction, the air outlet end of the second air guide plate 6 is located below the air inlet end of the first air guide plate 3. Thus, the second air guide plate 6 can guide at least part of the airflow in the air duct 72 to flow towards the lower end of the width direction of the air outlet 71 to the lower part of the first air guide plate 3, preventing at least part of the airflow in the air duct 72 from flowing out from the gap between the first air guide plate 3 and the upper end of the air outlet 71.

[0131] Meanwhile, the air inlet of the first air guide plate 3 is located near the upper end of the air outlet 71, and the first air guide plate 3 is generally vertically arranged. Therefore, the inner surface of the first air guide plate 3 can guide the hot airflow from the air outlet 71 downwards, causing the hot airflow to blow downwards. Furthermore, the lower part of the air outlet 71 is completely open in the width direction, so it will not interfere with the downward-blown hot air. Blowing the hot air downwards in the room facilitates the expansion and rise of hot air and the sinking of cold air, accelerating the alternation of hot and cold air and air circulation in the room, speeding up the indoor temperature rise, and thus improving the heating effect of the air conditioner 200.

[0132] In some embodiments of this utility model, such as Figure 13 As shown, when the air conditioner 200 is off, the second air guide plate 6 is located inside the first air guide plate 3 and inside the air outlet 71. The air conditioner 200 has a cooling downward sweeping state. In the cooling downward sweeping state, the first air guide plate 3 opens the air outlet 71. The air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. The first air guide plate 3 is inclined in the direction away from the air outlet 71 from top to bottom. The second air guide plate 6 is located outside the air outlet 71 and below the air outlet 71.

[0133] Understandably, in cooling mode, the second air guide plate 6 rotates downwards around the rotation axis located at the lower end of the air outlet 71 to below the air outlet 71 and tilts downwards in the direction away from the air outlet 71. This opens the air outlet 71, avoiding interference with the airflow flowing out of the air outlet 71. Furthermore, the second air guide plate 6 is located outside the air outlet 71, reducing wind resistance within the air duct 72 to ensure sufficient airflow from the air outlet 71. Simultaneously, the air inlet end of the first air guide plate 3 is spaced apart from both ends of the air outlet 71 in the width direction. In the vertical direction, the air outlet end of the first air guide plate 3 is located below or slightly below the air inlet end of the first air guide plate 3. This extends the air duct 72, ensuring that the airflow direction from the air outlet 71 is roughly the same as the extension direction of the air duct 72. This allows the airflow to flow smoothly out of the air outlet 71, ensuring sufficient airflow from the air conditioner 200, thereby achieving good circulation of cold air indoors and improving the cooling efficiency of the air conditioner 200.

[0134] In some embodiments of this utility model, such as Figure 14 As shown, when the air conditioner 200 is off, the second air guide plate 6 is located inside the first air guide plate 3 and inside the air outlet 71. The air conditioner 200 has a cooling upward sweeping state. In the cooling upward sweeping state, the first air guide plate 3 opens the air outlet 71. The air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. The first air guide plate 3 is inclined towards the air outlet 71 from top to bottom. The second air guide plate 6 is located outside the air outlet 71 and below the air outlet 71.

[0135] Understandably, in cooling mode, the second air guide plate 6 rotates downwards around the rotation axis located at the lower end of the air outlet 71 to below the air outlet 71 and tilts downwards in the direction away from the air outlet 71. This opens the air outlet 71, avoiding interference with the airflow flowing out of the air outlet 71. Furthermore, the second air guide plate 6 is located outside the air outlet 71, reducing wind resistance within the air duct 72 to ensure sufficient airflow from the air outlet 71. Simultaneously, the air inlet end of the first air guide plate 3 is spaced apart from both ends of the air outlet 71 in the width direction. In the vertical direction, the air outlet end of the first air guide plate 3 is located above or diagonally above the air inlet end of the first air guide plate 3. This guides the airflow diagonally upwards, thereby expanding the airflow range and angle of the air conditioner 200 in the vertical direction and enabling long-distance airflow, thus improving the uniformity of indoor temperature.

[0136] In some embodiments, when the air conditioner 200 is in cooling mode, the air inlet end of the first air guide plate 3 and the two ends of the air outlet 71 are spaced apart in the width direction. The air outlet end of the first air guide plate 3 can also swing back and forth between two positions located above and below the air inlet end of the first air guide plate 3, so that the first air guide plate 3 can sweep air back and forth in the vertical direction. At this time, both sides of the first air guide plate 3 in the thickness direction are guided by air, and the airflow can flow out from the air outlet 71 at different angles in the vertical direction, ensuring the vertical sweeping and air delivery state of the air conditioner 200, thereby enhancing the circulation effect of cold air in the room and improving the cooling efficiency of the air conditioner 200.

[0137] In some embodiments of this utility model, such as Figure 15 As shown, when the air conditioner 200 is off, the second air guide plate 6 is located inside the first air guide plate 3 and inside the air outlet 71. The air conditioner 200 has an anti-direct-blow mode. In the anti-direct-blow mode, the first air guide plate 3 opens the air outlet 71. The first air guide plate 3 is set horizontally. The air inlet end of the first air guide plate 3 is spaced apart from the two ends of the air outlet 71 in the width direction. The second air guide plate 6 is located outside the air outlet 71 and below the air outlet 71. In the direction from bottom to top, the second air guide plate 6 is tilted away from the air outlet 71.

[0138] Understandably, in the anti-direct-blow mode, the second air guide plate 6 rotates downward around the rotation axis located at the lower end of the air outlet 71 and tilts downward in the direction away from the air outlet 71. This guides at least a portion of the airflow flowing out of the air outlet 71 upward, preventing the airflow in the air duct 72 from blowing directly downward from the air outlet 71 onto the user. Simultaneously, the air inlet end of the first air guide plate 3 is spaced apart from both ends of the air outlet 71 in the width direction, and the first air guide plate 3 is generally horizontal. In this case, the first air guide plate 3 can guide at least a portion of the airflow flowing out of the air outlet 71 in a horizontal direction, increasing the distance the airflow travels and preventing the airflow from blowing directly onto the user from the air outlet 71, thereby improving the comfort of the airflow.

[0139] In some embodiments of this utility model, such as Figures 2-8 and Figures 10-19 As shown, at least one of the first air guide plate 3 and the second air guide plate 6 is provided with a plurality of spaced-apart micro-holes 31. When the airflow passes through the first air guide plate 3 or the second air guide plate 6 provided with micro-holes 31, the micro-holes 31 can disperse and refine the airflow, making the airflow more uniform, delicate and gentle, which is conducive to achieving the windless air outlet effect of the air conditioner 200 and improving the user experience.

[0140] For example, when a user needs cooling but doesn't want to be exposed to drafts, they can turn on the air conditioner 200's windless mode. When the air conditioner 200 is in windless mode, as shown in the examples in Figures 1 and 2, an air duct 72 connected to the air outlet 71 is formed inside the housing 7. The first air guide plate 3 can close the air outlet 71, and the second air guide plate 6 is located inside the first air guide plate 3 and inside the air outlet 71. Airflow flows from the air duct 72 inside the housing 7 to the air outlet 71 and is blown out after passing through the first air guide plate 3. The airflow is dispersed by the micropores 31, forming a diffused airflow, which can improve the turbulence during airflow and reduce the airflow velocity, improving the smoothness of airflow and thus enhancing the comfort of the airflow. This prevents the airflow from blowing directly onto the user after exiting the air outlet 71, achieving a windless airflow effect for the air conditioner 200, enriching the airflow effects of the air conditioner 200, and thus meeting different user needs, improving user comfort and experience.

[0141] It should be noted that the cross-sectional shape of the micro-hole 31 can be circular, polygonal, or a strip-shaped hole (slit), etc., and the specific shape is not limited here. For example, as shown in Figures 1 and 2, the cross-section of the micro-hole 31 is circular, which has a simple structure and is easy to process. Furthermore, when multiple micro-holes 31 are provided on the first air guide plate 3, the multiple micro-holes 31 can be arranged in an array on the first air guide plate 3. This allows for the arrangement of as many micro-holes 31 as possible on the first air guide plate 3 while ensuring a certain structural strength. This ensures sufficient airflow without affecting the airflow dispersion of the first air guide plate 3, thereby ensuring the airflow of the air outlet 71. Of course, multiple micro-holes 31 can also be provided only on the second air guide plate 6, or multiple micro-holes 31 can be provided on both the first air guide plate 3 and the second air guide plate 6.

[0142] In some embodiments of this utility model, such as Figure 3 and Figure 11 As shown, the air conditioner 200 has a windless state. In the windless state, the first air guide plate 3 opens the air outlet 71 from the bottom, and the second air guide plate 6 rotates to the outside of the air outlet 71. The air outlet end of the second air guide plate 6 abuts against the air outlet end of the first air guide plate 3 or the inner surface of the first air guide plate 3.

[0143] Understandably, in the windless state, the first air guide plate 3 is generally vertically positioned, and the second air guide plate 6 is generally horizontally positioned. The air outlet end of the second air guide plate 6 abuts against the air outlet end of the first air guide plate 3 or the inner surface of the first air guide plate 3, so that at least part of the air outlet 71 is confined between the first air guide plate 3 and the second air guide plate 6. An air duct 72 communicating with the air outlet 71 is formed inside the housing 7. The airflow flows from the air duct 72 to the air outlet 71 and passes through the micro-holes 31 on the first air guide plate 3 and / or the second air guide plate 6 and blows into the room. The airflow is dispersed by the micro-holes 31 and forms an airflow dispersion, which can improve the turbulence state during the airflow process, and at the same time reduce the airflow velocity and improve the smoothness of the airflow. This ensures that the airflow blown out from the air outlet 71 will not blow directly towards the user, thus achieving the windless air outlet effect of the air conditioner 200 and improving the user's comfort and experience.

[0144] In addition, compared with the first air guide plate 3 having micro-holes 31 and closing the air outlet 71 to achieve a windless state for the air conditioner 200, the air inlet end of the first air guide plate 3 is close to the upper end of the air outlet 71 and the first air guide plate 3 is generally vertically set, and the air outlet end of the second air guide plate 6 abuts against the first air guide plate 3. This can increase the air outlet area while achieving a windless air outlet state, thereby increasing the air volume of the air outlet 71.

[0145] In some embodiments of this utility model, such as Figure 20 As shown, the micro-hole 31 includes a first hole 311 and a second hole 312 arranged sequentially. The air outlet end of the first hole 311 and the air inlet end of the second hole 312 are connected. In the direction from the air inlet end of the micro-hole 31 to the air outlet end of the micro-hole 31, the cross-sectional area of ​​the first hole 311 gradually decreases, and the cross-sectional area of ​​the second hole 312 gradually increases. Therefore, when airflow passes through the micro-hole 31, the diameter of its flow channel first decreases and then increases. When airflow passes through the first hole 311, the diameter of the first hole 311 gradually decreases in the airflow direction, thereby increasing the resistance to airflow on the sidewall of the first hole 311, thus reducing the airflow velocity and improving the smoothness of airflow, thereby improving the windless airflow effect. Simultaneously, when airflow passes through the second hole 312, the diameter of the second hole 312 gradually increases in the airflow direction, which can prevent the micro-hole 31 from having excessive resistance to airflow, ensuring both the windless airflow effect and the airflow volume from the air outlet 71, thus ensuring the cooling effect of the air conditioner 200.

[0146] The air conditioner 200 according to an embodiment of the present invention is described below.

[0147] An air conditioner 200 according to an embodiment of the present utility model includes: a housing 7 and the above-described air guide plate assembly 100.

[0148] Specifically, such as Figures 1-19As shown, the housing 7 has an air outlet 71; one end of the first rod 1 is rotatably connected to the housing 7, and one end of the second rod 2 is rotatably connected to the housing 7 and is spaced apart from the first rod 1 in the width direction of the air outlet 71. The first air guide plate 3 is used to open or close the air outlet 71. The other end of the first rod 1 and the other end of the second rod 2 are both rotatably connected to the first air guide plate 3. When the first air guide plate 3 opens the air outlet 71, the upper end of the first air guide plate 3 flips downward.

[0149] According to the embodiment of the present invention, the air conditioner 200 forms a four-bar linkage by rotatably connecting the two ends of a first rod 1 and a second rod 2, which are spaced apart in the vertical direction, to the housing 7 and the first air guide plate 3, respectively. This allows the first air guide plate 3 to rotate at different angles and move to different positions, thereby achieving different air supply states of the air conditioner 200. Simultaneously, the upper side of the second rod 2 has a recessed clearance groove 11, which effectively avoids the end of the first air guide plate 3 near the second rod 2. This allows for a larger transmission range of the four-bar linkage within a limited space, effectively increasing the rotation angle range of the first air guide plate 3, i.e., increasing the vertical air supply range of the air conditioner 200. This, in turn, meets diverse user needs and improves user comfort and experience.
