The invention relates to a waterproof structure, an air conditioner and a motor home. The waterproof structure is used for a fan with an impeller arranged between a preset top or side air outlet and a motor, and comprises a cover waterproof structure suitable for being formed in the top or side air outlet and comprising a waterproof cover body and a cover water retaining ring extending downwards from the periphery of the cover body or close to the periphery; the fan water retaining ring is configured to surround the central mounting part of the impeller and extend from the central mounting part to the cover body, so that a first preset axial gap is formed between the fan water retaining ring and the cover body; the projection of the fan water retaining ring on the surface perpendicular to the center line of the center installation part is located in the projection of the cover water retaining ring on the same surface, a preset radial gap is formed between the fan water retaining ring and the cover water retaining ring, and the fan water retaining ring is configured to extend to the position between the cover body and a straight line. The straight line is composed of any point on the outer edge, close to the draught fan water retaining ring, of the cover water retaining ring and a point located on the periphery of the top or side air outlet and having the shortest distance from any point.
本发明涉及一种防水结构、空调、房车。该防水结构用于一种叶轮布置在预定的顶部或侧部出风口与电机之间的风机,包括:盖防水结构,其适于形成在顶部或侧部出风口中,并且包括防水的盖体和从盖体的外周或靠近外周向下延伸的盖挡水圈;和风机挡水圈,其配置成环绕叶轮的中心安装部并从中心安装部朝向盖体延伸,以在风机挡水圈与盖体之间形成第一预定轴向间隙,风机挡水圈在垂直于中心安装部的中心线的表面上的投影位于盖挡水圈在同一表面上的投影之内并在二者之间形成预定径向间隙,风机挡水圈配置成延伸到盖体与一条直线之间,直线由盖挡水圈的靠近风机挡水圈的外边缘上的任一点与位于顶部或侧部出风口的外周上的与任一点相距最短距离的一点构成。
