[0017] To facilitate understanding of the present invention, a more comprehensive description of the present invention is provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0018] See attached Figure 1-6 As shown, in this embodiment, an electric control box assembly structure for an air conditioner includes a frame 1 and an electric control box 2. The bottom of the frame 1 has a chamber for accommodating the electric control box 2, wherein the chamber is surrounded by a bottom plate 12 of the frame 1 and a plurality of boundary columns 11, that is, each boundary column 11 is vertically fixed at a corner position of the top surface of the chassis.

[0019] In this embodiment, a support beam 3 is further included that is fixedly placed in the chamber. The support beam 3 is used to support the bottom of the electric control box 2 so that an accommodation space is formed between the bottom of the electric control box 2 and the bottom plate 12. Specifically, a plurality of wire holes 22 are provided at the bottom of the electric control box 2 to facilitate the wires led out from the various electrical components inside the electric control box 2 to pass downward through the wire holes 22 to the accommodation space, which is more convenient for wiring connection and subsequent maintenance.

[0020] In this embodiment, the support beam 3 is integrally formed with at least one limit block 31 for interfering with the back of the electric control box 2. Thus, the top surface of the support beam 3 is used to limit the electric control box 2 in the height direction, and the limit block 31 is used to limit the electric control box 2 in the front and rear directions, thereby achieving a rapid positioning effect on the electric control box 2 and improving the efficiency and uniformity of assembly.

[0021] Furthermore, both side ends of the front face of the electric control box 2 are formed with connecting ribs 21 which respectively interfere with the inner side faces of the two adjacent boundary columns 11, and the connecting ribs 21 and the boundary columns 11 are fixedly connected by a number of screws, wherein each boundary column 11 is pre-drilled with a plurality of vertically arranged first screw holes, and accordingly, each connecting rib 21 is drilled with second screw holes which are aligned one by one with each first screw hole, and the screws are sequentially passed through the aligned first screw holes and the second screw holes to achieve a fixed connection between the electric control box 2 and the boundary columns 11, and since the electric control box 2 is pre-limited by the support beam 3 and the limit block 31, the alignment and locking operation of the screws is more convenient, thereby reducing the difficulty of assembly.

[0022] In this embodiment, the support beam 3 is formed by continuously bending a single sheet of plate to form an "inverted U-shaped" structure, and the two end portions of the support beam 3 at the bottom are bent outward as a whole to form connecting ears 32, wherein the connecting ears 32 and the base plate 12 are fixedly connected by a plurality of screws. The support beam 3 formed by bending a single sheet of plate as a whole not only ensures a certain structural strength, but also effectively reduces the production cost and difficulty. At the same time, the fixing method of the connecting ears 32 in combination with screws can reduce the difficulty of assembly.

[0023] In this embodiment, the limit block 31 is formed by punching and bending a single sheet of plate to form a sheet structure arranged perpendicular to the top surface of the support beam 3. In this embodiment, two limit blocks 31 arranged side by side are provided on the support beam 3 to jointly limit the electrical control box 2.

[0024] In this embodiment, a sealing cover plate 4 is also included that covers the chamber opening facing the front of the electric control box 2. During later maintenance, the sealing cover plate 4 can be removed to inspect the interior of the electric control box 2. Specifically, both side ends of the sealing cover plate 4 are formed with sealing ribs that are in conflict with the outer side surfaces of the boundary columns 11, and the sealing ribs and the boundary columns 11 are detachably connected by a number of screws, that is, the sealing ribs are formed with a plurality of vertically arranged third screw holes, and the outer side surfaces of the boundary columns 11 are formed with a plurality of vertically arranged fourth screw holes that are aligned one by one with each third screw hole. The installation of the sealing cover plate 4 can be completed by passing the preset screws through the relatively aligned third screw holes and fourth screw holes. When disassembling, the sealing cover plate 4 can be easily removed by removing the screws, which is convenient to operate.

[0025] In summary, the assembly structure of the electric control box 2 of this embodiment has the following characteristics:

[0026] 1. Compact structure: The assembly structure of the electric control box 2 is reasonably designed, which can effectively utilize the bottom space of the rack 1 and save additional installation space.

[0027] 2. Convenient wiring: The bottom of the electric control box 2 is provided with a plurality of wire holes 22, which are convenient for passing out and wiring of wires, simplifying the subsequent inspection and maintenance work.

[0028] 3. Quick positioning: The design of the support beam 3 and the limit block 31 enables the electric control box 2 to be quickly positioned, improving assembly efficiency and uniformity.

[0029] 4. Easy to assemble: The limiting function of the support beam 3 and the limit block 31 simplifies the operation of aligning and tightening the screws, reducing the difficulty of assembly.

[0030] 5. Cost-effectiveness: The support beam 3 is formed by bending a single piece of sheet material, which not only ensures structural strength but also effectively reduces production costs.

[0031] 6. Easy maintenance: The design of the sealing cover 4 makes the maintenance of the electric control box 2 simple, and the cover can be easily removed by removing the screws.

[0032] 7. Structural Strength: The sheet-like structure of the limit stop 31 is arranged perpendicular to the top surface of the support beam 3, thereby enhancing the structural stability of the electric control box 2.
