[0055] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 10 This utility model provides an indoor air conditioning unit 10, which includes a housing 100, an air guide plate 200, a first rotating shaft 300, and a drive device 400. The housing 100 has an air outlet 110 and a first through hole. The air guide plate 200 is rotatably disposed at the air outlet 110. The air guide plate 200 has a rotating hole coaxially arranged with the first through hole. The first rotating shaft 300 passes through the first through hole and is inserted into the rotating hole, and is configured to drive the air guide plate 200 to rotate. The drive device 400 is installed inside the housing 100, and the drive device 400 and the air guide plate 200 are respectively located on both sides of the first through hole. The drive device 400 has an output shaft portion 410, which is rotatably connected to the first rotating shaft 300 about an axis perpendicular to the first rotating shaft 300.

[0056] The assembly process in this embodiment is as follows: Figure 6 As shown, firstly, the output shaft 410 is rotated around an axis perpendicular to the first rotating shaft 300, so that the output shaft 410 and the first rotating shaft 300 have a certain angle; then, the rotating hole of the air guide plate 200 is aligned with the first through hole of the housing 100, the first rotating shaft 300 is passed through the first through hole and inserted into the rotating hole of the air guide plate 200, thus completing the initial fixing of the air guide plate 200. Figure 4 As shown, the output shaft 410 is then rotated to a set position on the other side of the first through hole, and the drive device 400 is mounted on the housing 100.

[0057] The working process of this embodiment is as follows: When the drive device 400 is running, the output shaft 410 rotates around its own axis and transmits the torque to the first rotating shaft 300, which in turn drives the air guide plate 200 to swing around the axis of the rotating hole, thereby realizing the adjustment of the air direction of the air outlet 110.

[0058] This embodiment significantly optimizes the assembly process between the air guide plate 200 and the drive device 400 by using a rotational connection design between the output shaft 410 of the drive device 400 and the first rotating shaft 300 about a direction perpendicular to the axis of the first rotating shaft 300. During assembly, the first rotating shaft 300 can be assembled with the rotating hole of the air guide plate 200 first, and then the drive device 400 can be assembled with the housing 100. This step-by-step operation completely solves the technical problem of inconvenient assembly of the air guide plate 200 and its drive device 400 in the prior art, significantly improving the assembly efficiency of the air guide plate 200 and the drive device 400, while reducing the risk of wear or deformation of the first rotating shaft 300 and the air guide plate 200 during the assembly process.

[0059] In some optional embodiments of this utility model, the output shaft includes a second rotating shaft, which is configured to output rotation, and the second rotating shaft is rotatably connected to the first rotating shaft about an axis perpendicular to the first rotating shaft.

[0060] like Figure 5 As shown, in some optional embodiments of this utility model, the output shaft portion 410 includes a second rotating shaft 411 and a connecting shaft 412. The second rotating shaft 411 is configured to output rotation; the second rotating shaft 411 is inserted into the shaft hole 4121 of the connecting shaft 412, and the second rotating shaft 411 and the connecting shaft 412 are coaxially arranged; the end of the connecting shaft 412 away from the second rotating shaft 411 is rotatably connected to the end of the first rotating shaft 300 away from the air guide plate 200. Specifically, the connecting shaft 412 and the first rotating shaft 300 are rotatably connected about an axis perpendicular to the first rotating shaft 300.

[0061] In this embodiment, the second rotating shaft 411 and the connecting shaft 412 form a power output unit. During operation, after the drive device 400 is started, the second rotating shaft 411 rotates around its own axis and transmits the rotational motion to the first rotating shaft 300 through the connecting shaft 412. After receiving the torque from the connecting shaft 412, the first rotating shaft 300 drives the air guide plate 200 to rotate smoothly around the axis of the rotating hole, thereby achieving precise adjustment of the air outlet 110 angle. During assembly, one end of the connecting shaft 412 is first rotatably connected to the first rotating shaft 300, and then the first rotating shaft 300 is inserted into the shaft hole 4121 of the connecting shaft 412, thereby achieving the connection between the output shaft 410 and the first rotating shaft 300.

[0062] In the previous embodiment, the second rotating shaft was connected to the motor of the drive device, which meant that when it was rotated to connect with the first rotating shaft, it was necessary to overcome the inertial resistance generated by the weight of the drive motor, requiring the operator to apply a large external force to complete the assembly. In this embodiment, since the connecting shaft 412 is lightweight, it can be quickly connected to the first rotating shaft 300 via a low-resistance rotating component such as a hinge pin; then, the second rotating shaft 411 of the drive device 400 is directly inserted into the shaft hole 4121 of the connecting shaft 412, and tool-free fixing can be achieved using an interference fit or a snap-fit ​​structure. Compared with the previous embodiment, the assembly process in this embodiment is simpler and easier to operate.

[0063] like Figure 5 and Figure 7 As shown, in some optional embodiments of this utility model, a first connecting block 310 is provided on the first rotating shaft 300. Two second connecting blocks 4122 are provided on the connecting shaft 412, and the two second connecting blocks 4122 are spaced apart. The first connecting block 310 is inserted between the two second connecting blocks 4122; the first connecting block 310 and the two second connecting blocks 4122 are rotatably connected.

[0064] Specifically, the first connecting block 310 and the two second connecting blocks 4122 are provided with mounting holes, which can be used to insert pins or rotating shafts. The extending direction of the mounting holes is perpendicular to the axial direction of the first rotating shaft 300. During assembly, the first connecting block 310 is inserted between the two second connecting blocks 4122, and the first connecting block 310 and the two second connecting blocks 4122 are rotatably connected together by pins or rotating shafts. This embodiment has the beneficial effect of facilitating manufacturing and assembly.

[0065] like Figure 8 and Figure 9 As shown, in some optional embodiments of this utility model, a connecting frame 140 is provided on the housing 100, and a first through hole is provided on the connecting frame 140. A baffle 320 is provided on the first rotating shaft 300, and the baffle 320 is located on the side of the first through hole away from the air guide plate 200. The baffle 320 is configured to contact the connecting frame 140 to limit the position of the first rotating shaft 300 inserted into the rotating hole.

[0066] In this embodiment, the rapid and precise assembly of the first rotating shaft 300 is achieved by setting the baffle 320 and the connecting bracket 140. Specifically, the baffle 320 is located on the side of the first perforation away from the air guide plate 200. When the first rotating shaft 300 is inserted into the perforation, the baffle 320 and the connecting bracket 140 contact to form a stop structure, directly limiting the axial insertion depth of the first rotating shaft 300, avoiding the tedious operation of repeatedly measuring or relying on experience to judge the insertion position during assembly.

[0067] like Figure 2 and Figure 3As shown, in some optional embodiments of this utility model, the housing 100 is further provided with a second through hole, which is coaxially arranged with the first through hole. The air guide plate 200 is provided with a third rotating shaft 500, which passes through the second through hole; the rotating hole and the third rotating shaft 500 are respectively provided at both ends of the air guide plate 200.

[0068] During the assembly process, firstly, align the third rotating shaft 500 of the air guide plate 200 with the second through hole on the housing 100 and insert it to initially fix one end of the air guide plate 200; then align the rotating hole at the other end of the air guide plate 200 with the first through hole of the housing 100, and then insert the first rotating shaft 300 from the side of the connecting frame 140 into the first through hole and into the rotating hole until the baffle 320 on the first rotating shaft 300 contacts the connecting frame 140 and the insertion stops.

[0069] This embodiment ensures that the air guide plate 200 is subjected to force at both ends by adding a third rotating shaft 500 and a second through hole, thereby eliminating the risk of twisting of the air guide plate 200 caused by force on one side.

[0070] like Figure 4 As shown, in some optional embodiments of this utility model, the air guide plate 200 is provided with a mounting base 210, and a rotating hole is provided on the mounting base 210. The axial direction of the rotating hole is parallel to the extension direction of the air guide plate 200. Specifically, the axial direction of the rotating hole extends in the left-right direction.

[0071] like Figure 1 and Figure 2 As shown, in some optional embodiments of this utility model, the housing 100 includes a panel 130, an air outlet 110 is disposed on the panel 130, and a first through hole is disposed on the inner side of the panel 130. The drive device 400 is mounted on the inner side of the panel 130.

[0072] In this embodiment, the drive device 400 and the first through hole are directly installed inside the panel 130, which saves space inside the housing 100 and also facilitates the assembly efficiency of the drive device 400, the guide plate, and the housing 100. In addition, after removing the panel 130, the drive device 400, the first rotating shaft 300, and the air guide plate 200 can be directly exposed, thereby facilitating the inspection or maintenance of the above-mentioned components.

[0073] In some optional embodiments of this utility model, the housing 100 further includes a rear housing, and the panel 130 is detachably disposed at the front opening of the rear housing.

[0074] like Figure 4As shown, in some optional embodiments of this utility model, the drive device 400 further includes a motor housing 420 and a motor 430. The motor housing 420 has a receiving space; a connecting structure is provided on the peripheral wall of the motor housing 420, and the connecting structure is connected to the panel 130. The motor 430 is installed in the receiving space, and the motor 430 has an output shaft portion 410.

[0075] In this embodiment, the motor 430 is installed inside the motor housing 420, and the motor housing 420 can be fixedly connected to the panel 130 through a connecting structure. The motor housing 420 provides shock-absorbing and sealed protection for the motor 430, which can reduce operating noise.

[0076] like Figure 4 As shown, in some optional embodiments of this utility model, the connecting structure includes at least two ear plates 421, each ear plate 421 being parallel to the axis of the first through hole. At least two connecting posts 150 are provided on the panel 130, and each ear plate 421 is mounted on one connecting post 150. Specifically, the connecting ears and the corresponding connecting posts 150 can be connected by screws or by a snap-fit ​​structure. This embodiment has the advantages of simple structure and ease of processing, manufacturing, and assembly.

[0077] In some optional embodiments of this utility model, the peripheral wall of the motor box 420 is also provided with protruding ribs, which are in contact with the inner surface of the panel 130.

[0078] In this embodiment, by setting the ribs, the support function of the motor 430 can be guaranteed, preventing the motor 430 from being suspended and unstable due to the connection of only the connecting column 150, and improving the motion stability of the motor 430.

[0079] In some optional embodiments of this utility model, the peripheral wall of the connecting column 150 is provided with reinforcing ribs, and the protruding ribs are connected to the inner surface of the panel 130 to increase the structural stability of the connecting column 150, thereby improving the motion stability of the motor 430.

[0080] In some optional embodiments of this utility model, a positioning plate is provided on the first rotating shaft 300. When the first rotating shaft 300 rotates in a first direction, one side of the positioning plate contacts the inner surface of the panel 130 for limiting; when the first rotating shaft 300 rotates in a second direction, the other side of the positioning plate contacts the inner surface of the panel 130 for limiting; the first direction is opposite to the second direction; the positioning plate is perpendicular to the first rotating shaft 300.

[0081] In this embodiment, by setting a positioning plate, the maximum forward and reverse rotation angle of the first rotating shaft 300 can be limited, thereby ensuring that the air guide plate 200 rotates only within a preset angle range, and avoiding collision between the air guide plate 200 and the housing 100 or damage to the transmission components due to excessive rotation.

[0082] In some optional embodiments of this utility model, when one side of the positioning plate contacts the inner surface of the panel 130, the air guide plate 200 closes the air outlet 110, and the axis of rotation between the output shaft portion 410 and the first rotating shaft 300 is parallel to the inner surface of the panel 130. The positioning plate is perpendicular to the first rotating shaft 300, and the positioning plate and the baffle 320 are the same plate.

[0083] In this embodiment, the positioning plate and the baffle 320 are set as the same plate. While ensuring the limit of the insertion hole depth and the limit of the rotation angle of the first rotating shaft 300, the structure can be simplified and the production cost can be reduced.

[0084] like Figure 1 and Figure 2 As shown, in some optional embodiments of this utility model, the panel 130 faces forward, and the air outlet 110 is located at the lower part of the panel 130; the panel 130 is also provided with an air inlet 120, which is located above the air outlet 110. The indoor unit 10 of the air conditioner also includes a sealing plate 700, which is rotatably installed at the air inlet 120 for opening or closing the air inlet 120.

[0085] like Figure 1 , Figure 2 and Figure 10 As shown, in some optional embodiments of this utility model, the indoor unit 10 of the air conditioner further includes a guide rail 601, a slider 602, a connecting rod 603, and a telescopic arm 604. The guide rail 601 is disposed on the inner wall of the enclosed plate 700 and extends in a direction perpendicular to the rotation axis of the enclosed plate 700. The slider 602 is disposed on the guide rail 601. One end of the connecting rod 603 is fixedly connected to the slider 602; the connecting rod 603 is inclined relative to the extension direction of the guide rail 601. The telescopic arm 604 is disposed inside the housing 100, and is movably disposed along the inner and outer directions of the housing 100. The front end of the telescopic arm 604 is rotatably connected to the other end of the connecting rod 603, and the telescopic arm 604 drives the enclosed plate 700 to rotate through the connecting rod 603, the slider 602, and the guide rail 601.

[0086] Specifically, the guide rail 601 has a groove, and the slider 602 is located within the groove. When the air conditioner is turned on, the telescopic arm 604 moves from the inside to the outside along the housing 100, driving the slider 602 to slide along the guide rail 601 via the connecting rod 603, thereby driving the sealing plate 700 to rotate around its rotation axis to open the air inlet 120. When the air conditioner is turned off, the slider 602 drives the telescopic arm 604 to move in the opposite direction, and the connecting rod 603 drives the slider 602 to slide in the opposite direction along the guide rail 601, pulling the sealing plate 700 back to the position where it completely blocks the air inlet 120.

[0087] This embodiment utilizes the lever effect of the inclined connecting rod 603 to optimize force transmission, continuously pressing the slider 602 against the inner wall of the guide rail 601 groove, avoiding gaps between the slider 602 and the groove, reducing jamming, and improving motion stability.

[0088] In some optional embodiments of this utility model, the air conditioner indoor unit 10 is a wall-mounted air conditioner indoor unit.

[0089] In some optional embodiments of this utility model, the air conditioner indoor unit 10 is an embedded air conditioner indoor unit.
