[0186] In the present application, in the vertical direction, when the contact point between the water and the guide surface is below the rotating shaft of the outdoor fan, the guide surface drives the water to move forward and upward. At the same time, in the length direction of the outdoor casing, the guide surface drives the water to move to the side away from the rotating shaft of the outdoor fan. If the outdoor air outlet is large enough, the water can flow out of the outdoor containing cavity through the outdoor air outlet.

[0187] In the present application, in the vertical direction, when the contact point between the water and the guide surface is above the rotating shaft of the outdoor fan, the guide surface drives the water to move forward and upward. At the same time, in the length direction of the outdoor casing, the guide surface drives the water to move to the side close to the rotating shaft of the outdoor fan, and the water flows out of the outdoor containing cavity through the outdoor air outlet.

[0188] In the present application, in the vertical direction, when the contact point between the water and the guide surface is above the rotating shaft of the outdoor fan, the guide surface drives the water to move forward and upward. At the same time, in the length direction of the outdoor casing, the distance between the guide surface and the rotating shaft of the outdoor fan remains unchanged, and the water can flow out of the outdoor containing cavity through the outdoor air outlet.

[0189] In this application, reference is made to Figure 10-12 The intersection line of the cylindrical outer surface with the rotating axis of the outdoor fan as the central axis and the guide surface is the guide contour line 8221112.

[0195] In the present application, the end of the guide contour line close to the windward side is the rear end of the guide contour line.

[0196] The end of the guide contour line close to the leeward side is the front end of the guide contour line, which can make the water move forward and upward after being broken, so as to facilitate the water to be discharged from the outdoor receiving cavity through the outdoor air outlet.

[0197] In this application, Fig.10 The arrow in the figure indicates the direction of water movement.

[0198] In the present application, the outdoor housing may include a housing top panel 814 .
