[0043] Figure 1 This is a schematic structural diagram of the indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 8 This utility model provides an indoor unit 100 for an air conditioner, which includes a body 110, a panel 120, and at least two elastic arms 180. An air inlet 160 is formed on the body 110. The panel 120 is rotatably disposed at the air inlet 160 and is used to open and close the air inlet 160. The elastic arms 180 are spaced apart, with one end of each elastic arm 180 connected to the panel 120 and the other end abutting against the inner wall of the body 110. The elastic arms 180 are configured to apply a force to the panel 120 to open or close the air inlet.

[0044] In this embodiment, the indoor unit of the air conditioner achieves smooth opening and closing of the panel 120 through the elastic deformation of the elastic arms 180. When the air conditioner is started, the panel 120 can be rotated around the pivot by the drive mechanism to open the air inlet. At this time, one end of the multiple spaced elastic arms 180 rotates with the panel 120, and the other end undergoes elastic deformation due to abutting against the inner wall of the unit body 110, continuously applying a spring force to the panel 120 in the same direction of movement, assisting the drive mechanism in completing the opening and closing action. When the air conditioner is turned off, the spring force of the elastic arms 180 acts in the opposite direction, working with the drive mechanism to reset the panel 120 and block the air inlet. The elastic design of the elastic arms 180 can adapt to the mechanical requirements of different opening and closing angles of the panel 120, ensuring the continuity of action. In this embodiment, the panel can also be manually rotated to open or close the air inlet.

[0045] In this embodiment, at least two elastic arms 180 are provided between the inner wall of the panel 120 and the body 110. The multiple elastic arms 180 are spaced apart and can apply force evenly. By utilizing the buffering characteristics of the deformation of the elastic material, the sudden change in mechanical resistance during the movement of the panel 120 can be effectively mitigated, thereby effectively preventing the panel from jamming during the opening or closing of the air inlet, and thus effectively preventing overload failure of the drive motor due to jamming.

[0046] In some optional embodiments of this utility model, the indoor unit further includes at least two rotating arms 121, one end of each rotating arm 121 being connected to the panel 120, and the other end being rotatably mounted on the body 110; elastic arms 180 are arranged correspondingly to the rotating arms 121, and the elastic arms 180 are connected to the panel 120 through the rotating arms 121. Specifically, the elastic arms 180 are located on the rear side of the rotating arms, and one end of the elastic arms 180 is connected to the end of the rotating arms near the panel. The elastic arms allow all rotating arms to rotate synchronously.

[0047] Compared to the structure where the elastic arm 180 is directly mounted on the panel 120, this embodiment mounts the elastic arm 180 to the panel via a rotating arm 121. On one hand, the force application point of the elastic arm 180 is changed from a direct connection to the panel 120 to transmission via the rotating arm 121. Utilizing the lever principle, the opening and closing action of the panel 120 requires less effort. On the other hand, the assembly process between the elastic arm 180, the rotating arm 121, the panel 120, and the body 110 is simpler and easier to operate. Furthermore, the combined action of the rotating arm 121 and the elastic arm 180 results in smoother and more reliable movement of the panel 120, which helps reduce the load on the drive motor and decreases the risk of failure.

[0048] like Figure 2 and Figure 3 As shown, in some optional embodiments of this utility model, the body 110 is provided with a clearance hole for the rotating arm 121 to pass through, so that the two ends of the rotating arm 121 are respectively located on the inner and outer sides of the body 110. The body 110 is provided with a mounting bracket 1111, which has a mounting hole. The rotating shaft 1211 is inserted into the mounting hole, and one end of the rotating shaft 1211 is fixedly connected to or integrally formed with the rotating arm.

[0049] like Figure 4 As shown, in some embodiments of this utility model, each rotating arm 121 includes a first arm portion 1213 and a second arm portion 1214. A rotating shaft 1211 is disposed on the second arm portion 1214; the line connecting the two endpoints of the first arm portion 1213 along its length is the first connecting line, and the line connecting the two endpoints of the second arm portion 1214 along its length is the second connecting line. The angle between the first connecting line and the panel 120 is 20 to 45 degrees, and the angle between the second connecting line and the first connecting line is 45 to 70 degrees. The length of the first connecting line is 1.2 to 2 times the length of the second connecting line.

[0050] For example, the angle between the first connecting line and the panel can be 20°, 25°, 30°, 40°, or 45°; preferably, the angle between the first connecting line and the panel is 25° to 30°. The angle between the second connecting line and the first connecting line can be 45°, 50°, 60°, 65°, or 70°; preferably, the angle between the second connecting line and the first connecting line is 65°. The length of the first connecting line can be 1.2 times, 1.4 times, 1.5 times, 1.8 times, or 2 times the length of the second connecting line; preferably, the length of the first connecting line can be 1.3 times the length of the second connecting line.

[0051] In this embodiment, the above-described configuration allows the panel 120 to have a large rotation angle, enabling it to open to a wider angle. This facilitates adjustment of the air intake volume and also makes it easier to perform maintenance on the indoor unit. Furthermore, the rotating arm in this embodiment, while having a large rotation angle, has a small size, requiring minimal installation space. This reduces manufacturing costs and simplifies assembly.

[0052] like Figure 2 As shown, in some optional embodiments of this utility model, the rotation axis of the panel 120 is parallel to the lateral direction of the body 110. That is, the rotation shaft on the rotating arm 121 is arranged along the lateral direction of the body 110. This embodiment is particularly suitable for situations where the indoor unit 100 is a wall-mounted indoor unit or a horizontally recessed indoor unit.

[0053] In some embodiments of this utility model, the rotation axis of the panel 120 is parallel to the vertical direction of the body 110. That is, the rotation shaft on the rotating arm 121 is arranged along the vertical direction of the body.

[0054] In some optional embodiments of this utility model, the rotating arm 121 is fixedly connected to the panel 120.

[0055] In some optional embodiments of this utility model, the rotating arm 121 and the panel 120 are integrally formed. Specifically, the integral formation of the rotating arm 121 and the panel 120 simplifies the structure, reduces the number of assembly parts, and reduces assembly errors and the risk of loosening at the connection. The integral molding design eliminates the gaps or frictional losses of traditional split connections (such as hinges or welding), improves the linkage rigidity of the rotating arm 121 and the panel 120, makes the torque transmission more direct and efficient, and reduces abnormal noises or vibrations caused by the relative displacement of components during movement. This further optimizes the smoothness and reliability of the panel 120's movement and reduces the risk of mechanical fatigue after long-term use.

[0056] In some optional embodiments of this utility model, the rotating arm 121 is fixedly connected to the elastic arm 180.

[0057] In some optional embodiments of this utility model, the rotating arm 121 and the elastic arm 180 are integrally formed. Specifically, the integral formation of the rotating arm 121 and the elastic arm 180 (such as integral injection molding or compression molding) can completely eliminate the assembly interface between the two, avoiding torque transmission deviation caused by loosening, wear, or tolerance accumulation of connecting parts; at the same time, it reduces the number of parts and assembly complexity, and lowers production and maintenance costs. In addition, after the overall structure is enhanced, the fatigue resistance is significantly improved, and it is less likely to produce residual deformation or fracture risk under long-term high-frequency operation, further extending the service life of the component.

[0058] In some optional embodiments of this utility model, the indoor unit 100 further includes at least one drive mechanism mounted on the body 110 for driving the panel 120 to rotate. In this embodiment, by providing a drive mechanism, it is easier to operate the opening and closing angle and speed of the precise control panel, improving the degree of automation and reducing the complexity of manual operation.

[0059] like Figure 2 As shown, in some optional embodiments of this utility model, there are two drive mechanisms, which are respectively arranged on both sides of the width direction of the air inlet 160.

[0060] like Figures 4 to 6 As shown, in some optional embodiments of this utility model, at least one guide rail 130 is provided on the inner side of the panel 120. The guide rail 130 is provided in a one-to-one correspondence with the drive mechanism.

[0061] Each drive mechanism includes a drive arm 141 and a drive unit. Each drive arm 141 has a sliding part at its end that slides with the guide rail 130; the drive unit is used to drive the drive arm 141 to move in the inward and outward directions along the body 110.

[0062] The working principle of the drive mechanism is as follows: When the air conditioner is turned on, the drive unit drives the drive arm 141 to move from the inside to the outside along the body 110, thereby driving the sliding part 150 to slide along the guide rail 130, driving the panel 120 to rotate around the pivot, so that the panel 120 smoothly unfolds from the closed state to a preset opening angle to open the air inlet 160. When the air conditioner is turned off, the drive unit drives the drive arm 141 to move in the opposite direction, the sliding part 150 slides in the opposite direction along the guide rail, and pulls the panel 120 back to the position of completely blocking the air inlet 160. Specifically, when the air inlet 160 is located on the front side of the body 110, the drive arm 141 can move along the front-back direction of the housing. When the air inlet 160 is located on the upper side of the body 110, the drive arm 141 can move along the vertical direction of the housing. In this embodiment, the cooperation of the guide rail and the sliding part may make the movement of the drive arm smoother, reduce friction, and thus reduce wear. In some alternative embodiments, the panel can also be driven to rotate by a linkage mechanism or the like.

[0063] In some optional embodiments of this utility model, such as Figure 5 and Figure 6As shown, the drive unit is a gear and rack mechanism. The gear and rack mechanism includes a gear 142, a rack, and a drive motor 143. A transmission box 144 is provided inside the machine body 110, and the drive motor 143 and gear 142 are installed inside the transmission box 144. The rack is mounted on the drive arm 141, and the gear 142 meshes with the rack. The output end of the drive motor 143 is connected to the gear 142. The drive motor is configured to drive the gear 142 to rotate, thereby driving the drive arm 141 to move in the inward and outward directions along the machine body 110. In this embodiment, the gear and rack mechanism has the advantages of high transmission accuracy, long service life, and stable and reliable operation. Using a gear and rack mechanism to drive the drive arm ensures the stability and reliability of the drive arm 141's movement.

[0064] In some optional embodiments of this utility model, the sliding part 150 is a slider, which is fixedly disposed at the end of the drive arm 141.

[0065] like Figure 8 As shown, in some optional embodiments of this utility model, the sliding part 150 is a pulley, which is rotatably mounted on the end of the drive arm 141 via a mounting shaft 151. When the drive arm 141 moves in the inward and outward directions along the body 110, the drive arm 141 drives the pulley to roll along the groove of the guide rail 130. Compared with a slider, this embodiment uses a pulley as the sliding part, replacing sliding friction with rolling friction, reducing the wear rate of the sliding part and the guide rail, and improving the smoothness and stability of the overall movement.

[0066] In some optional embodiments of this utility model, the guide rail 130 includes a first guide rail portion 131, the first guide rail portion 131 having a first sliding groove, and a sliding portion 150 installed in the first sliding groove. The sliding portion 150 is a pulley or a slider.

[0067] like Figures 6 to 8 As shown, in some optional embodiments of this utility model, each guide rail 130 includes a first guide rail portion 131 and a second guide rail portion 132. The first guide rail portion 131 has a first sliding groove. The second guide rail portion 132 has a second sliding groove, and the openings of the first sliding groove and the second sliding groove are arranged opposite to each other.

[0068] Each sliding part includes a first sliding part installed in a first sliding groove and a second sliding part installed in a second sliding groove. Specifically, a mounting shaft 151 is fixedly provided at the end of the drive arm 141, and a sliding part is provided in the first sliding groove and the second sliding groove respectively, with the two sliding parts respectively located at both ends of the axial direction of the mounting shaft. Preferably, both sliding parts 150 are pulleys, and the two pulleys are mounted in the first sliding groove and the second sliding groove via the mounting shaft.

[0069] Compared to the previous embodiment, this embodiment adds a second guide rail 132 and its corresponding second slide groove, allowing the two sliding parts 150 at the end of the drive arm 141 to slide within the first and second slide grooves respectively. This dual-guide rail design not only further enhances the stability of the panel 120's opening and closing action, but also improves the load-bearing capacity and durability of the entire drive system by distributing the force on the sliding parts, reducing the risk of system failure due to wear or malfunction of a single guide rail, thereby improving the overall performance and reliability of the air conditioner indoor unit 100.

[0070] like Figure 5 and Figure 6 As shown, in some optional embodiments of this utility model, the first guide rail portion 131 and the second guide rail portion 132 are detachably connected.

[0071] This embodiment employs a detachable connection design for the first guide rail section 131 and the second guide rail section 132, significantly improving the convenience of processing, assembly, and maintenance. Specifically, the split guide rail structure is simpler to process than the integrated type; at the same time, the easy disassembly and reassembly of the guide rail greatly facilitates daily cleaning and maintenance as well as repair and replacement work in case of failure, effectively reducing maintenance costs.

[0072] In some optional embodiments of this utility model, the first guide rail portion 131 and the second guide rail portion 132 are fastened by a threaded connection.

[0073] like Figure 7 As shown, in some optional embodiments of this utility model, one end of the first guide rail portion 131 is provided with a first insertion portion 1312, the extension direction of the first insertion portion 1312 being parallel to the extension direction of the first slide groove; the other end of the first guide rail portion 131 is provided with a second insertion portion 1311, the extension direction of the second insertion portion 1311 being perpendicular to the extension direction of the first slide groove. The second guide rail portion 132 is provided with a first insertion groove 1322 and a second insertion groove 1321, the first insertion groove 1322 being used for insertion and engagement with the first insertion portion 1312, and the second insertion groove 1321 being used for insertion and engagement with the second insertion portion 1311.

[0074] This embodiment achieves a stable and flexible plug-in connection between the first guide rail section 131 and the second guide rail section 132 by providing a first insertion part 1312 parallel to the slide groove and a second insertion part 1311 perpendicular to the slide groove on the first guide rail section 131, and a corresponding insertion groove on the second guide rail section 132. This structure not only enhances the stability and reliability of the guide rail connection but also facilitates quick installation and disassembly, improving assembly efficiency and maintenance convenience.

[0075] like Figures 4 to 6As shown, in some optional embodiments of this utility model, one end of the guide rail 130 is rotatably connected to the panel 120, and the other end of the guide rail 130 is detachably connected to the panel 120. Specifically, a mounting base 123 is provided on the inner wall surface of the panel 120, and one end of the guide rail 130 is rotatably mounted on the mounting base 123 via a rotating shaft, the axis of which is perpendicular to the extension direction of the guide rail. The guide rail 130 and the panel 120 can be detachably connected by a snap-fit ​​connection or a threaded connection. Preferably, the guide rail 130 and the panel 120 are connected by a snap-fit ​​122. More preferably, multiple snap-fit ​​structures are provided between the guide rail 130 and the panel 120, so that the installation stability of the guide rail 130 can be ensured when the guide rail 130 and the panel 120 are fixed together.

[0076] In this embodiment, when the guide rail 130 is fixed to the panel 120, the panel 120 can only open to a preset angle, such as 35 degrees. Figure 5 As shown, after separating the guide rail 130 from the panel 120, the panel 120 can be opened 90 degrees, which is more conducive to air intake at the air inlet 160 and also makes it easier to remove the filter at the air inlet 160, thus facilitating the cleaning of the filter.

[0077] like Figure 5 As shown, in some optional embodiments of this utility model, an air outlet 170 is also formed on the body 110, and the air inlet 160 and the air outlet 170 are disposed on the front side of the body 110, with the air inlet 160 located above the air outlet 170. A rotating arm 121 is disposed at the bottom of the panel 120. Specifically, the body 110 includes a front shell 111, on which an air inlet 160 and an air outlet 170 are formed. A heat exchange air duct connecting the air inlet 160 and the air outlet 170 is formed inside the body 110; the air inlet 160 and the air outlet 170 are distributed along the vertical direction. The drive arm 141 is inclined relative to the front shell 111.

[0078] In this embodiment, both the air inlet 160 and the air outlet 170 are located on the front side of the unit, which facilitates the embedded installation of the indoor unit in a cabinet or wall to meet the diverse usage needs of users. Furthermore, the rotating arm 121 is located at the lower edge of the panel 120, which can prevent the intake airflow and the blower airflow from interfering with each other.

[0079] In some embodiments of this utility model, the indoor unit 100 is a recessed air conditioning indoor unit, a wall-mounted air conditioning indoor unit, a floor-standing air conditioning indoor unit, or other air conditioning indoor units.

[0080] Preferably, the indoor unit 100 is a recessed air conditioning indoor unit.
