[0040] Please refer to Figures 3 to 5 The edge of the volute fixing plate 2 extends to form a first flange 21, the edge of the top plate 1 or the bottom plate 4 extends to form a second flange 41, and the electric control box sheet metal 3 is provided with a first notch 311 and a second notch 312, the first flange 21 is matched with the first notch 311, and the second flange 41 is matched with the second notch 312. In this way, the first flange 21 formed on the volute fixing plate 2 is matched with the first notch 311 on the electric control box sheet metal 3, and the second flange 41 formed on the bottom plate 4 is matched with the second notch 312 on the electric control box sheet metal 3, which not only can pre-fix the electric control box sheet metal 3 in the receiving cavity, but also is convenient for subsequent screw connection, and can reduce the screws required for installing the electric control box sheet metal 3, so as to realize stable installation of the electric control box sheet metal 3.

[0041] The electric control box sheet metal 3 comprises a sheet metal body 31 and a flange connected to the edge of the sheet metal body 31, and a screw hole can also be formed on the flange to facilitate screw connection of the side wall of the receiving cavity. The first notch 311 and the second notch 312 are both formed on the sheet metal body 31. In this way, the first notch 311 and the second notch 312 are both formed on the sheet metal body 31, so that the first flange 21 formed by directly extending and bending the edge of the volute fixing plate 2 can be inserted into the first notch 311, and the second flange 41 formed by directly extending and bending the edge of the bottom plate 4 can be inserted into the second notch 312, so that the structure is simple and convenient to manufacture.

[0042] The width of the first gap 311 and the second gap 312 gradually decreases from the edge of the sheet metal body 31 to the inside of the sheet metal body 31. In this way, after the first folded edge 21 and the second folded edge 41 are inserted into the respective corresponding gaps, the first folded edge 21 and the second folded edge 41 can play the role of automatic centering and stable installation.

[0043] The first gap 311 and the second gap 312 are respectively arranged at diagonal positions on the sheet metal body 31. In this way, the distance between the first gap 311 and the second gap 312 is large, and after the first folded edge 21 and the second folded edge 41 are fixed to the first gap 311 and the second gap 312 respectively, the position of the electric control box sheet metal 3 can be more stably fixed.

[0044] Please refer to Figure 3 , the first folded edge 21 is an L-shaped folded edge, and the first folded edge 21 includes an extension section 211 and an insertion section 212.
