[0041] The following describes the air conditioner indoor unit 100 according to an embodiment of the present utility model with reference to the drawings.

[0042] As Figures 2 - 12 shown, the air conditioner indoor unit 100 according to an embodiment of the present utility model includes a chassis 1 and an electronic control assembly 2.

[0043] Among them, a first positioning structure is provided on the chassis 1. The electronic control assembly 2 is located above the chassis 1 and is connected to the chassis 1 through a fastener 7. A second positioning structure is provided on the electronic control assembly 2. The second positioning structure cooperates with the first positioning structure to limit the electronic control assembly 2 in the up-down direction and the front-rear direction of the air conditioner indoor unit 100.

[0044] Thus, during the assembly process of the chassis 1 and the electronic control assembly 2, first, the second positioning structure cooperates with the first positioning structure to limit the electronic control assembly 2 in the up-down direction and the front-rear direction of the air conditioner indoor unit 100, thereby realizing the pre-positioning of the electronic control assembly 2, ensuring the accurate installation position of the electronic control assembly 2, reducing the operation process of adjusting the position of the electronic control assembly 2 during the process of connecting the electronic control assembly 2 and the chassis 1 by the fastener 7, and further reducing the assembly difficulty and improving the assembly efficiency.

[0045] Meanwhile, the second positioning structure and the first positioning structure ensure the accurate installation position of the electronic control component 2, effectively reducing the errors and failures caused by position deviation, improving the reliability of the air conditioner indoor unit 100, and extending the service life. In addition, the second positioning structure and the first positioning structure ensure the accurate installation position of the electronic control component 2, enabling the fasteners 7 connecting the electronic control component 2 and the chassis 1 to be driven in by automated equipment, meeting the requirements of automated production.

[0046] For the air conditioner indoor unit 100 according to an embodiment of the present invention, the chassis 1 is provided with a first positioning structure. The electronic control component 2 is located above the chassis 1 and is connected to the chassis 1 through fasteners 7. The electronic control component 2 is provided with a second positioning structure. By cooperating the second positioning structure with the first positioning structure, it is used to limit the electronic control component 2 in the up-down direction and the front-back direction of the air conditioner indoor unit 100, thereby realizing the pre-positioning of the electronic control component 2, ensuring the accurate installation position of the electronic control component 2, reducing the position adjustment operation process of the electronic control component 2 during the process of connecting the fasteners 7 to the electronic control component 2 and the chassis 1, and further reducing the assembly difficulty, improving the assembly efficiency, and meeting the requirements of automated production.

[0047] In some embodiments of the present invention, such as Figure 3 , Figure 9 and Figure 10 shown, the electronic control component 2 includes an electronic control box 21 and a limiting member 22. Among them, the limiting member 22 is located on the front side of the electronic control box 21 in the front-back direction, and the second positioning structure is provided on the limiting member 22.

[0048] Thus, by cooperating the limiting member 22 with the first positioning structure, the electronic control component 2 is limited in the up-down direction and the front-back direction of the air conditioner indoor unit 100. At the same time, by providing the limiting member 22 for cooperating with the first positioning structure, during the assembly process of the electronic control component 2 and the chassis 1, the limiting member 22 can reach the predetermined position more quickly and accurately, further improving the assembly efficiency, and the electronic control box 21 and the limiting member 22 can be produced separately, improving the production efficiency.

[0049] In some embodiments of the present invention, such as Figures 3 - 6 , Figure 10 and Figure 12 shown, the second positioning structure includes a clamping protrusion 221 provided on the limiting member 22. The clamping protrusion 221 protrudes towards the left or right side. The first positioning structure includes a recessed portion 11 provided at the front end of the chassis 1. The front side of the recessed portion 11 is open. The clamping protrusion 221 is adapted to be clamped in the recessed portion 11 for limiting the electronic control component 2 in the up-down direction.

[0050] It can be understood that since the limiting member 22 is located on the front side of the electric control box 21 in the front-back direction, and the recessed portion 11 is provided on the front short side of the chassis 1 with the front side open, it is convenient for the clamping protrusion 221 to extend into the recessed portion 11, thereby reducing the assembly difficulty and improving the assembly efficiency. At the same time, by the clamping protrusion 221 being adapted to be clamped in the recessed portion 11, the electric control assembly 2 is limited in the up-down direction, further ensuring the pre-positioning of the electric control assembly 2 and improving the reliability. In addition, by the clamping protrusion 221 protruding towards the left or right, the limiting member 22 can be adapted to different models, improving the versatility.

[0051] In some embodiments of the present invention, as Figure 6 shown, in the front-to-back direction, the top wall of the recessed portion 11 slopes downward.

[0052] It can be understood that the clamping protrusion 221 enters the recessed portion 11 in the front-to-back direction. Thus, by setting the top wall of the recessed portion 11 to slope downward in the front-to-back direction, the top wall of the recessed portion 11 plays a guiding role, thereby guiding the recessed portion 11 to quickly and accurately extend into the recessed portion 11, reducing the adjustment and calibration time during the assembly process, avoiding assembly jams, and thus improving the assembly efficiency.

[0053] At the same time, in the front-to-back direction, by the top wall of the recessed portion 11 sloping downward, it is convenient for the clamping protrusion 221 to be clamped in the recessed portion 11, further ensuring the up-down direction limit of the electric control assembly 2 and improving the reliability.

[0054] In some embodiments of the present invention, as Figures 8 - 12 shown, the second positioning structure includes a groove 222 on the lower surface of the limiting member 22, and the first positioning structure includes a first positioning rib 12 provided on the chassis 1. The first positioning rib 12 is located in the groove 222 and is used to limit the electric control assembly 2 in the front-back direction.

[0055] Thus, by the first positioning rib 12 being located in the groove 222, the second positioning structure and the first positioning structure are cooperated to realize the front-back direction limit of the electric control assembly 2, further ensuring the pre-positioning of the electric control assembly 2 and improving the reliability. At the same time, by the first positioning rib 12 being located on the chassis 1 and the groove 222 being located on the lower surface of the limiting member 22, the electric control assembly 2 can be assembled in the up-down direction during the assembly process, reducing the assembly difficulty and improving the assembly efficiency.

[0056] In some embodiments of the present invention, as Figure 12As shown, the front surface of the first positioning rib 12 slopes upward in the front-to-back direction. Thus, with such a setting, the front surface of the first positioning rib 12 serves as a guiding function, so that during the process of assembling the electronic control component 2 onto the chassis 1 in the up-and-down direction, the adjustment and calibration time during the assembly process is reduced, and it is convenient for the first positioning rib 12 to be located within the groove 222, avoiding assembly jams, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0057] In some embodiments of the present invention, as Figure 12 shown, the rear surface of the first positioning rib 12 slopes downward in the front-to-back direction. Thus, with such a setting, the rear surface of the first positioning rib 12 serves as a guiding function, so that during the process of assembling the electronic control component 2 onto the chassis 1 in the up-and-down direction, the adjustment and calibration time during the assembly process is reduced, and it is convenient for the first positioning rib 12 to be located within the groove 222, avoiding assembly jams, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0058] In some embodiments of the present invention, as Figure 12 shown, the front surface of the first positioning rib 12 slopes upward in the front-to-back direction, and the rear surface of the first positioning rib 12 slopes downward in the front-to-back direction. Thus, with such a setting, both the rear and front sides of the first positioning rib 12 serve as guiding functions, further reducing the assembly difficulty and improving the assembly efficiency. At the same time, when the chassis 1 is an injection-molded part, such a setting facilitates demolding at the first positioning rib 12, improving the production efficiency.

[0059] In some embodiments of the present invention, as Figure 10 shown, the groove 222 is provided with a reinforcing rib 223, and the reinforcing rib 223 divides the groove 222 into a plurality of sub-grooves 2221, and the first positioning rib 12 is located within one of the sub-grooves 2221. Thus, the structural strength of the groove 222 is effectively enhanced by the reinforcing rib 223, ensuring the fitting strength between the first positioning rib 12 and the sub-groove 2221 it is located in, thereby ensuring the limitation of the electronic control component 2 in the front-to-back direction and improving the overall reliability.

[0060] In some embodiments of the present invention, as Figure 2 , Figure 3 , Figure 11 and Figure 12 shown, the chassis 1 is provided with a mounting groove 13, the electronic control component 2 is disposed within the mounting groove 13, and at least one of the two inner walls of the mounting groove 13 opposite to each other in the left-right direction is provided with a second positioning rib 131 for limiting the movement of the electronic control component 2 in the left-right direction, and the second positioning rib 131 is used to limit the electronic control component 2 in the left-right direction.

[0061] Thus, the electric control component 2 is limited in the left-right direction by the second positioning rib 131, so that the electric control component 2 is limited in the up-down direction, the front-back direction, and the left-right direction, further ensuring the accurate installation position of the electric control component 2, reducing the operation process of adjusting and correcting the position of the electric control component 2 during the connection process of the fastener 7 connecting the electric control component 2 and the chassis 1, thereby reducing the assembly difficulty and improving the assembly efficiency. At the same time, the installation groove 13 provides an installation point for the electric control component 2, further reducing the assembly difficulty.

[0062] In some embodiments of the present invention, Figure 3 and Figure 12 As shown, in the direction from front to back, the second positioning rib 131 is tilted downward. It can be understood that the electric control component 2 is assembled on the chassis 1 in the direction from top to bottom. Therefore, in the direction from front to back, the second positioning rib 131 is tilted downward, and the second positioning rib 131 improves the limiting effect of the electric control component 2 in the left and right directions, thereby improving reliability.

[0063] Furthermore, the electric control assembly 2 includes an electric control box 21 and a limiting member 22 , and the second positioning rib 131 limits the electric control box 21 in the left-right direction.

[0064] In some embodiments of the utility model, the second positioning rib 131 is one or more. When the second positioning rib 131 is multiple, the multiple second positioning ribs 131 are spaced apart in the front-to-back direction. Thus, through such an arrangement, the second positioning rib 131 is adapted to chassis 1 of different models, thereby improving versatility. At the same time, when the second positioning rib 131 is multiple, the positioning effect of the second positioning rib 131 on the electric control component 2 in the left-right direction is improved, thereby improving reliability.

[0065] In some embodiments of the utility model, the position-limiting member 22 includes a main body and a convex 221, the convex 221 is located on the left or right side of the main body and protrudes toward the side away from the main body, the lower surface of the main body has a groove 222, the front end of the chassis 1 is provided with a recessed portion 11, the front side of the recessed portion 11 is open, the convex 221 is suitable for being clamped in the recessed portion 11, and is used to limit the position of the electric control component 2 in the up-down direction, the upper surface of the chassis 1 has a first positioning rib 12, the first positioning rib 12 is located in the groove 222, and is used to limit the position of the electric control component 2 in the front-back direction, and the groove 222 and the convex 221 form a second positioning structure of the position-limiting member 2. Therefore, by such a setting, the electric control component 2 is limited in the up-down direction and the front-back direction of the air-conditioning indoor unit 100.

[0066] At the same time, if Figure 10 and Figure 12As shown, the main body part further has a first fastening hole 23. The groove 222 is located on the side of the first fastening hole 23 away from the clamping protrusion 221. The chassis 1 has a second fastening hole 14 disposed opposite to the first fastening hole 23. The fastener 7 passes through the first fastening hole 23 and the second fastening hole 14. Thus, after the electronic control component 2 is limited in the up-down direction and the front-back direction of the indoor air conditioner 100, the fastener 7 passes through the first fastening hole 23 and the second fastening hole 14 to realize the fixed connection between the electronic control component 2 and the chassis 1, completing the assembly of the electronic control component 2 and the chassis 1.

[0067] In some embodiments of the present invention, as Figure 1 shown, the indoor air conditioner 100 further includes a panel 3, a front frame 4, a wind deflector 5, and an evaporator 6. The front frame 4 and the chassis 1 are connected to form an accommodation space. The evaporator 6 is located in the accommodation space. The panel 3 covers the front frame 4, and the wind deflector 5 is disposed at the air outlet of the front frame 4. It should be noted that the panel 3, the front frame 4, the wind deflector 5, and the evaporator 6 are prior art for those of ordinary skill in the art, and will not be elaborated herein.
