Top air blowing device of automatic car washing machine

The invention discloses a top air blowing machine of an automatic car washing machine in the technical field of high voltage electric power engineering. The top air blowing device of the automatic carwashing machine comprises a gantry 1 and one or multiple air blowing mouths 2, wherein the air blowing mouths 2 are arranged at the top of the gantry 1 and are longitudinally arranged along a car orlongitudinally arranged, the air blowing directions of the air blowing mouths 2 point to the top of the car, and the air blowing mouths 2 are of an arc shape or a U shape integrally, so that includedangles between partial air directions of the air blowing mouths 2 and the top of the car are acute angles. The top air blowing machine of an automatic car washing machine avoids the problem of poor effect of air drying in a single direction, air blowing direction from the middle to the edge of the top of the car is gradually changed due to the arc-shaped or U-shaped structure, and water drops canbe blown off effectively. 本发
