Specifically, as shown in fig. 2, the back surface of the volute component 120 refers to an outer wall surface of the housing, which is on the volute casing formed by the volute component 120 and forms the air outlet and deviates from the air outlet direction. Since the volute of the fan is often formed into an involute shape wound around one end, the volute is generally formed into a circular arc, and during assembly, space distribution is mainly performed according to the maximum length, width and height of components, that is, when the volute component 120 distributes an assembly space, space distribution is performed according to the maximum length, width and height of the volute component 120, and a rectangular parallelepiped assembly space is obtained through distribution, so that an underutilized cavity, namely a back surface area of the volute component 120, exists at a corner of the rectangular parallelepiped assembly space relative to the rectangular parallelepiped assembly space to which the volute component 120 is distributed, and therefore, the circuit integrated device 130 is mounted on the back surface of the volute component 120, that is, the circuit integrated device 130 is mounted in the underutilized cavity at the corner of the rectangular parallelepiped assembly space, and therefore, it is not necessary to separately search for an assembly space for the circuit integrated device 130, but directly utilize an underutilized corner portion in the assembly space of the volute component 120, therefore, the assembly structure is simplified to the maximum extent, the assembly is compact, and the miniaturization is facilitated.

Moreover, since the back surface of the volute component 120 is the outer wall surface of the housing on the volute forming the air outlet and deviating from the air outlet direction, the back surface of the volute component 120 is close to the air conditioner rear cover plate 110, so that the assembly is convenient, and the operations such as installation and maintenance are convenient.

Thus, in order to mount the circuit integrated device 130 on the rear surface of the scroll housing assembly 120, that is, to mount the circuit integrated device 130 in the cavity of the underutilized corner at the corner of the rectangular parallelepiped assembling space, it is necessary to provide the circuit integrated device 130 in a triangular prism structure corresponding to the underutilized cavity at the corner.

Specifically, as shown in fig. 2 to 4, the mounting structure of the circuit integrated device 130 includes a mounting case 131, a mounting plate 132, a wire clamp 133 and a terminal plate 134, the mounting plate 132 is fixedly mounted on the back surface of the scroll housing assembly 120 through screw holes at four corners thereof, the mounting plate 132 has a first boss 132a at an upper portion thereof, the terminal plate 134 is fixedly mounted on the first boss 132a by screws, the mounting plate 132 has a second boss 132b at a lower portion thereof, the wire clamp 133 is fixedly mounted on the second boss 132b by screws, the mounting case 131 has two mounting grooves 137 at lateral sides thereof, corresponding to the two mounting buckles 136 on the side surface of the mounting plate 132, the mounting buckles 136 are formed by cutting and bending part of the plate on the mounting plate 132 upwards, the upper ends of the mounting buckles 136 are bent inwards to form hook parts, and the mounting grooves 137 on the side surface of the mounting box 131 are transversely moved to enable the hook parts on the upper ends of the mounting buckles 136 to be inserted into the mounting grooves 137. The first boss 132a and the second boss 132b may be formed by stamping the mounting plate 132, or hollow portions corresponding to the first boss 132a and the second boss 132b may be formed on the mounting plate 132, the first boss 132a and the second boss 132b are used as sheet metal parts, the outer side of each of the first boss 132a and the second boss 132b is in a boss shape, and the inner side of each of the first boss 132a and the second boss 132b is correspondingly in a cavity shape and is welded to the hollow portion of the mounting plate 132. Thus, the inner side of the mounting plate 132 has a cavity shape corresponding to the boss shape outside the first boss 132a and the second boss 132 b. Therefore, on the one hand, an assembly space is provided for the screw installation on the first boss 132a and the second boss 132b, and on the other hand, the concave cavity structure inside the first boss 132a can be matched with the installation boss 122, so that the installation of the wire clamping clip 133 and the wiring board 134 is facilitated while the embedding limit is realized to improve the assembly stability.

The other side of the mounting box 131 is further provided with a protruding fixing structure 135, the fixing structure 135 is provided with a threaded hole, and after the mounting groove 137 on the side of the mounting box 131 is transversely moved to enable the upper hook portion of the mounting buckle 136 to be inserted into the mounting groove 137, the threaded hole on the fixing structure 135 corresponds to the threaded hole on the back surface of the volute component 120, so that the mounting box 131 is fixed on the back surface of the volute component 120 through threads. Therefore, when the mounting box 131 needs to be opened to operate the interior thereof, the mounting box 131 can be completely removed, only the screws on the fixing structure 135 are removed, the mounting buckle 136 on the other side is connected with the mounting groove 137, and the mounting buckle 136 is partially hinged due to the bending structure, so that the mounting box 131 can be partially turned over and opened by the mounting buckle 136. The convenience of operation installation dismantlement is improved.

The wiring structure of the circuit integrated device 130 is shown in fig. 4, the connecting wire 150 sequentially passes through the wiring board 134 and the wire clamp 133, and is covered by the mounting box 131 after being pressed tightly by the screw on the wiring board 134 and the wire hole on the wire clamp 133, the side wall and the bottom wall of the mounting box 131 are respectively provided with a wire inlet hole 138 and a wire outlet hole 139, and the connecting wire 150 is respectively accommodated and limited by the wire inlet hole 138 and the wire outlet hole 139. Furthermore, the rear cover plate 110 is mounted on the hollow portion to cover the circuit integrated device 130, and the connection line 150 is led out from the connection port 112, so that the outlet of the circuit integrated device 130 and the connection port 112 on the rear cover plate 110 are at the same height, the connection line 150 can directly come out from the connection port 112 on the rear cover plate 110 after coming out from the circuit integrated device 130, the structure is simplified, the length required by the connection line 150 is shortened, the problems that the line body is bent and worn due to the fact that the mounting position and the mounting angle of the connection line 150 are not matched are avoided, meanwhile, the outlet of the circuit integrated device 130 corresponds to the connection port 112 on the rear cover plate 110, after-sale operators can easily and visually see the connection position, and operations such as mounting and maintenance are convenient.
