In the description of the present invention, "plurality" means two or more.
Referring to fig. 5-7, alternatively, the positioning columns 1214 and the positioning holes 132 are all three and are all distributed in a triangle shape, for example, when the electric control plate 13 is substantially rectangular, one positioning hole 132 is formed in the middle of the left end of the electric control plate 13, and the other two positioning holes 132 are respectively formed in the upper and lower parts of the right end of the electric control plate 13, so that the three positioning holes 132 are distributed in a triangle shape. By arranging three positioning columns 1214 and three positioning holes 132 to match, and the positioning columns 1214 and the positioning holes 132 are distributed in a triangular shape, the electric control plate 13 is precisely connected with the inner box body 12, and the electric control plate 13 is prevented from shaking in the inner box body 12.
Referring to fig. 5-7, according to some embodiments of the present invention, the portion of the outer case 11 accommodating the inner case 12 is a first accommodating cavity 112, the portion of the outer case 11 accommodating the component 14 is a second accommodating cavity 113, the area of the cross section of the second accommodating cavity 113 is larger than the area of the cross section of the first accommodating cavity 112, the cross section is perpendicular to the arrangement direction of the inner case 12 and the component 14, for example, the arrangement direction of the inner case 12 and the component 14 is an up-down direction, and the cross section is parallel to a horizontal plane. Since the electronic control board 13 is of a plate-like structure, the dimension of the electronic control board 13 in the thickness direction (the thickness direction of the electronic control board 13 is in the front-rear direction) is small, and the dimension of the inner case 12 accommodating the electronic control board 13 in the front-rear direction can also be designed small, so that the area of the cross section of the first accommodating chamber 112 can be designed small. The size of the component 14 in the front-rear direction may be larger, for example, when the component 14 is a transformer, the size of the component 14 in the front-rear direction is larger, so that the area of the cross section of the second accommodating cavity 113 accommodating the component 14 needs to be designed larger to ensure that the component 14 is accommodated in the outer case 11 as a whole. The area of the cross section of the second accommodating cavity 113 is larger than that of the cross section of the first accommodating cavity 112, so that the space requirement of the component 14 is met, the first accommodating cavity 112 is designed smaller, the whole volume of the electric control box assembly 1 is reduced while the space requirement of the inner box body 12 is met, other components of the air conditioner are convenient to set when the electric control box assembly 1 is applied to the air conditioner, and the whole volume is reduced.

The inner case 12 and the mounting bracket 121 constitute a stepped structure, for example, the mounting bracket 121 protrudes rearward in the front-rear direction so that the inner case 12 and the mounting bracket 121 integrally form a stepped structure. Since the electronic control board 13 has a plate-like structure, the size of the electronic control board 13 in the front-rear direction is small, and the size of the inner case 12 accommodating the electronic control board 13 in the front-rear direction can also be designed small. And the size of the component 14 in the front-rear direction may be larger, the mounting bracket 121 may protrude rearward to increase the contact area of the mounting bracket 121 with the component 14, so as to improve the connection strength of the component 14 and the mounting bracket 121. Meanwhile, the mounting bracket 121 protrudes backwards so that the overall structure of the inner box body 12 and the mounting bracket 121 is matched with that of the outer box body 11, wherein the mounting bracket 121 protruding backwards is accommodated in the second accommodating cavity 113 and corresponds to the protruding part of the back plate 115, the inner box body 12 is accommodated in the first accommodating cavity 112 and corresponds to the recessed part of the back plate 115, the space utilization rate in the outer box body 11 is improved, and the size of the electronic control box assembly 1 is reduced.
