The drainage structure is arranged on a bottom plate of the air conditioner and comprises an evaporation cavity drainage groove, a fresh air cavity drainage groove, a water diversion nozzle, a water collecting cover and a communicating pipe, the bottom plate is divided into a top face and a bottom face, and the top face faces the interior of an air conditioner cavity; openings of the evaporation cavity drainage groove and the fresh air cavity drainage groove face the bottom face and are fixed to the bottom face, an inlet of the communicating pipe communicates with an outlet of the fresh air cavity drainage groove and extends into the evaporation cavity drainage groove, and an outlet of the communicating pipe is formed in the outlet of the evaporation cavity drainage groove. The diversion nozzle is fixed on the bottom plate and is provided with a through stepped hole, the reducing part of the diversion nozzle is a transition surface, one end, far away from the transition surface, of a large hole of the stepped hole is a diversion nozzle inlet, the other end of the stepped hole is a diversion nozzle outlet, the diversion nozzle inlet is flush with the top surface, and the outlet is formed in the fresh air cavity drainage groove; the water collecting cover is fixed above the water diversion nozzle, and a water inlet is formed in the bottom end of one side wall. The problem that an existing drainage structure cannot discharge condensate water on the premise that a fresh air cavity and an evaporation cavity conduct centralized drainage is solved.

    本发明公开了一种轨道车辆空调防止冷凝水反流的排水结构,设置在空调的底板上,包括:蒸发腔排水槽、新风腔排水槽、引水嘴、集水罩和连通管,底板分为顶面和底面,顶面朝向空调腔内;蒸发腔排水槽和新风腔排水槽开口均朝向底面,均固定在底面上,连通管进口连通新风腔排水槽出口,伸入蒸发腔排水槽内部,其出口设在蒸发腔排水槽出口内;引水嘴固定在底板上,设有贯通的台阶孔,其变径处为过渡面,台阶孔大孔远离过渡面的一端为引水嘴入口,台阶孔另一端为引水嘴出口,引水嘴入口与顶面平齐,出口设在新风腔排水槽内;集水罩固定在引水嘴上方,一侧壁底端开设有进水口。克服现有排水结构无法在新风腔和蒸发腔集排的前提下满足冷凝水排出的问题。
