[0002] In the structure of an air conditioner indoor unit, the air intake grille is one of the most crucial components. It not only plays a vital role in guiding air into the indoor unit, ensuring proper ventilation and cooling / heating cycles, but also significantly impacts the overall appearance and internal structural stability of the indoor unit.

[0003] Air intake grilles present numerous inconveniences in terms of installation and disassembly. Firstly, many grilles employ complex snap-fit ​​structures or require numerous screws for fixation. Snap-fit ​​structures are prone to aging and deformation after prolonged use, leading to loosening of the clips, insecure grille installation, noise, or even detachment, affecting the normal operation of the air conditioner. Furthermore, disassembling the clips often requires specialized tools or specific operating skills, increasing the difficulty and time cost of repair and replacement. Secondly, while screw fixation is relatively secure, the frequent tightening and loosening of screws during installation and disassembly is not only cumbersome but also prone to losing screws.

[0023] Please see Figure 1 In this embodiment, the connecting component includes connecting frames 2 that are fixedly connected to the left and right sides of the air inlet grille body 1 respectively. A connecting plate 3 is fixedly connected between the inner left and right side walls of the connecting frame 2. Threaded rods 4 are rotatably connected to the upper and lower sides of the connecting plate 3. A turn wheel 5 is fixedly connected to the outer side of the threaded rod 4. A threaded cylinder 6 is threadedly connected to the outer side of the threaded rod 4.

[0024] Specifically, the outer wall of the threaded cylinder 6 is square, and the left and right sides of the threaded cylinder 6 are fixedly connected to the limiting blocks 7. The inner left and inner right walls of the connecting frame 2 are provided with limiting grooves that are adapted to the limiting blocks 7. The limiting blocks 7 are slidably connected to the inner side of the corresponding limiting grooves.

[0025] It should be noted that this design is intended to restrict the rotation of the threaded cylinder 6. When the threaded rod 4 rotates, due to the sliding restriction of the limiting block 7 within the limiting groove, the threaded cylinder 6 can only move linearly along the axial direction of the threaded rod 4, thereby enabling the threaded cylinder 6 to extend or retract.

[0026] Specifically, the top and bottom of the inner side of the connecting frame 2 are provided with openings that are compatible with the threaded cylinder 6, and the height of the connecting frame 2 is equal to the height of the air inlet grille body 1.

[0027] It should be noted that the threaded cylinder 6 can extend out of the connecting frame 2 through the corresponding port.

[0028] Specifically, three reinforcing rods 8 are fixedly connected to the back of the air intake grille body 1, and the three reinforcing rods 8 are arranged sequentially along the left and right directions of the air intake grille body 1.

[0029] It should be noted that the reinforcing rod 8 can enhance the structural strength of the air intake grille body 1 and prevent the air intake grille from deforming or being damaged by external forces during use.

[0030] On the other hand, this application also relates to an indoor air conditioning unit, including an indoor unit body 9, a base 10, and an air inlet grille of any of the above embodiments.

[0031] Specifically, the front of the inner side of the indoor unit body 9 is provided with an installation port that matches the air inlet grille, and the inner top wall and inner bottom wall of the installation port are provided with positioning slots that match the threaded cylinder 6.

[0032] It should be noted that an installation opening adapted to the air inlet grille is provided on the front inner side of the indoor unit body 9, providing space for the installation of the air inlet grille. The inner top and bottom walls of the installation opening are provided with positioning slots adapted to the threaded cylinder 6. When the threaded cylinder 6 extends out of the connecting frame 2, it can be accurately inserted into the positioning slot, realizing precise positioning and firm connection between the air inlet grille and the indoor unit body 9.

[0033] Specifically, a reinforcing plate 1001 is fixedly connected to all four sides of the base 10, and the reinforcing plate 1001 is triangular in shape, with an angle of 90 degrees between the reinforcing plate 1001 and the base 10.

[0034] It should be noted that the triangular reinforcing plate 1001 has the characteristic of good stability, which can enhance the structural strength of the base 10, improve the load-bearing capacity of the base 10, and ensure the stability of the air conditioner indoor unit during placement and use.

[0035] The working principle of the above embodiments is as follows:

[0036] Place the air inlet grille body 1 with the connecting components into the mounting port of the indoor unit body 9 of the air conditioner. Rotate the actuating wheels 5 on the connecting frames 2 on the left and right sides of the air inlet grille body 1, which in turn drives the threaded rod 4 to rotate. As the threaded rod 4 rotates, the threaded cylinder 6 moves outward along the axial direction of the threaded rod 4 under the action of the threaded connection. The threaded cylinder 6 extends out of the connecting frame 2 through the through-hole on the connecting frame 2. Continue to rotate the actuating wheels 5 so that the extended threaded cylinder 6 is inserted into the positioning slot of the mounting port of the indoor unit body 9. When the threaded cylinder 6 is fully inserted into the positioning slot, the air inlet grille body 1 and the indoor unit body 9 achieve precise positioning and firm connection.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
