The first water baffle portion 15 is used to block a large part of rainwater that reaches the connecting portion 143 through the first wiring trough section 141, reduce the amount of rainwater that flows along the connecting portion 143 to the second wiring trough section 142, or prevent rainwater from entering the second wiring trough section 142, thereby improving the problem of rainwater entering the electrical installation cavity 13 along the wiring trough 14, thereby reducing the risk of electrical components in the electrical installation cavity 13 becoming damp and failing.

[0045] In some embodiments of this application, see Figures 1 to 7 The casing 11 includes a top cover 111 and a partition 112 connected to each other. The first wiring trough section 141 is arranged on the lower surface of the top cover 111. The partition 112 is used to separate the fan installation cavity 12 and the electrical appliance installation cavity 13 to further prevent rainwater from entering the electrical appliance installation cavity 13 through the fan installation cavity 12.

[0048] In some embodiments of this application, see Figures 1 to 7The first wiring trough section 141 includes a first side baffle portion 1411 and a first side wall 1412 that are oppositely arranged, and the second wiring trough section 142 includes a second side baffle portion 1421 and a second side wall 1422 that are oppositely arranged, and the first side baffle portion 1411 and the second side baffle portion 1421 are connected at an acute angle; the second baffle portion 1421 is located on the side of the second side wall 1422 close to the electrical installation cavity 13, and the second baffle portion 1421 is located between the first baffle portion 15 The first water baffle portion 15 is connected to the second side wall 1422 and extends to the area between the first side water baffle portion 1411 and the second water baffle portion 1421. On the one hand, it can reduce the amount of rainwater penetrating from the second side wall 1422 into the electrical appliance installation cavity 13. On the other hand, it can rebound the rainwater flowing through the first side water baffle portion 1411 and / or the second water baffle portion 1421 to the first water baffle portion 15, thereby further reducing the amount of rainwater entering the electrical appliance installation cavity 13.

[0049] In some embodiments of the present application, the second water baffle portion 1421 is arranged parallel to the first water baffle portion 15 .

[0050] In some embodiments of the present application, the acute angle is 55° to 65°, for example, it can be 55°, 57°, 60°, 63°, 65° or a value between any two of the foregoing values, so as to further improve the effect of rainwater rebounding to the first water baffle portion 15, thereby further reducing the amount of rainwater entering the electrical installation cavity 13.
