DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 shown.

[0019] An improved electric control box assembly for an indoor unit of an air conditioner comprises a box body 1.

[0020] The box body 1 is in a rectangular box shape, and its panel 10 is detachable for easy installation and maintenance.

[0021] The box body 1 is provided with a main control board 2, a sub-control board 7 and a terminal block 5. The main control board 2 is smaller than the back plate of the box body 1 and is fixed to the upper part of the back plate. The sub-control board 7 is fixed to the bottom plate of the box body 1 and is perpendicular to the back plate and is separated from the main control board 2 to meet the heat dissipation requirements. The terminal block 5 is installed at the lower part of the back plate and is adjacent to the two sides of the box body 1 with the sub-control board 7, so that the two are separated.

[0022] The main control panel 2 and the auxiliary control panel 7 are respectively fixed to the back panel and the bottom panel through the aircraft frame 9, so as to facilitate installation and disassembly.

[0023] The back plate of the box body 1 is provided with a strong / weak current hole 8. There are two strong / weak current holes, which can have different apertures, and are used for passing strong and weak current wires respectively. The strong / weak current holes are respectively provided with a wire sleeve 11 to prevent damage to the wires. Preferably, the strong / weak current hole 8 is arranged near the main control board 2 for easy wiring.

[0024] A power cord hole 4 is provided on the side plate adjacent to the terminal block 5. A wire passing sleeve 11 is also provided on the power cord hole 4 to prevent the power cord from being cut by the edge of the power cord hole. The terminal block 5 is installed on a terminal block bracket 6.

[0025] The terminal block bracket 6 includes a horizontal plate 61 and a vertical plate 62 that are perpendicular to each other. The horizontal plate 61 is in a "U" shape, and the bottom is fixed on the back plate. The terminal block 5 is fixed on the horizontal plate 61 to raise the position of the terminal block 5, facilitating wiring operations. The upper end of the vertical plate 62 is provided with a wire pressing buckle mounting surface 63. The wire pressing buckle mounting surface 63 can be formed by bending the upper end of the vertical plate 62 outward and cooperating with the wire pressing component 3 to limit the wires connected to the terminal block 5.

[0026] The wire pressing component 3 includes a wire pressing buckle 31 and a wire pressing seat 32. The wire pressing seat 32 is a strip-shaped thin plate and is fixed on the wire pressing buckle mounting surface 63. There are two wire pressing buckles 31, both of which are in a "U" shape, and are connected to the wire pressing hole mounting surface 63 by screws to limit and fix the power cord between the wire pressing seat 32 and the wire pressing buckle 31. Preferably, the heights of the two wire pressing buckles 31 are different to better meet the installation requirements.

[0027] Without increasing the volume of the existing electronic control box, the present invention can make full use of the space inside the electronic control box and make its internal structure more compact by reasonably arranging the main control board and the sub-control board. Moreover, it can also make installation and maintenance more convenient and improve operation efficiency.

[0028] Parts not involved in the present invention are the same as or can be implemented using existing technologies.
