Drying system of automatic car washing machine

Abstract

The invention discloses a drying system of an automatic car washing machine. The drying system comprises a first gantry, a second gantry, a top blowing assembly, side blowing assemblies and a control board. The top blowing assembly comprises a first top draught fan set, a second top draught fan set, a top draught fan wind tunnel, a distance measuring sensor and a servo motor; the first top draught fan set is connected with a first top draught fan swinging mechanism, the second top draught fan set is connected with a second top draught fan swinging mechanism, the wind outlets of the first top draught fan set and the second top draught fan set communicate to the left wind inlet and the right wind inlet of the top draught fan wind tunnel, and the wind outlets of the top draught fan wind tunnel follow the shape of the car and have a fixed distance relative to the car body surface; and the servo motor, the distance measuring sensor, the side blowing assemblies and draught fan startup optoelectronic switches arranged on the first gantry are connected with the control board. According to the drying system of the automatic car washing machine, the drying effect is good, the rigid impact, vibration and noise when the top blowing machine assembly is lifted can be avoided, and the service life of electric-mechanical components is favorably prolonged.

Description

technical field [0001] The invention relates to the field of automatic car washing machines, in particular to a drying system of the automatic car washing machine. Background technique [0002] At present, in the existing automatic car washing machines, the combination of top blowing and side blowing is mostly used to dry the car body. Among them, the top blower is controlled by a photoelectric switch. When the photoelectric switch detects that the top surface of the car is The blower goes up, and when the photoelectric switch detects no car, the top blower goes down. It can be seen that this control method will not only make the lifting motor used to lift the top blower start and stop frequently, but also cause the top blower to go up and down frequently. Rigid impact, vibration and noise will have a serious impact on the service life of electrical and mechanical components such as the lifting motor and the top blower; in addition, in the process of drying the car body, the...
