The invention relates to the technical field of motor home air conditioners, particularly provides a fan mounting structure and a motor home air conditioner, and aims to solve the problem that noise is generated due to friction and collision between a volute and a fan. In order to achieve the purpose, the invention provides the fan mounting structure which comprises a chassis, the fan assembly is fixedly connected to the chassis, and the length from the fan assembly to a cantilever of the chassis is L; the volute is arranged on the chassis, and a preset gap is formed between the fan body and the volute; and setting the sum of the deviation of the chassis, the fan assembly and the volute for reducing the preset gap as a, and enabling the fan assembly to deflect towards the direction for increasing the preset gap by taking the joint of the fan assembly and the chassis as the vertex. The invention further provides a motor home air conditioner which adopts the fan mounting structure. The deflection angle is set and counteracts the deviation a, the preset gap is still reserved between the fan body and the volute, and the conditions of friction, collision or noise and the like are avoided.
本发明涉及房车空调技术领域,具体提供一种风扇安装结构和房车空调,旨在解决因蜗壳与风扇摩擦、碰撞、发出噪音的问题。为此目的,本发明提供一种风扇安装结构,包括底盘;风扇组件,风扇组件固定连接于底盘,风扇组件至底盘的悬臂长度为L;蜗壳,其设置在底盘上,风扇本体与蜗壳之间设置有预设间隙;设定底盘、风扇组件与蜗壳使预设间隙缩小的偏差之和为a,则使风扇组件以与底盘连接处为顶点向使预设间隙增大的方向偏转度。本发明还提供一种房车空调,其采用上述的风扇安装结构。本发明通过设置偏转角度,与偏差a相抵消,风扇本体与蜗壳之间依然会保留预设间隙,不会发生摩擦、碰撞或噪音等情况。
