In general, a separate device for ventilating the polluted air in a vehicle is not equipped in the vehicle. Accordingly, in order to ventilate the polluted air in the vehicle, the windows of the vehicle should be opened and closed.
FIG. 1 is a schematic view showing an airflow using a window or windows at the time of ventilation in a conventional vehicle. As shown in FIG. 1, the external air which flows into the front windows of the running vehicle does not proceed to an operator an a passenger on the front seats, in other words, on the driver's andpassenger ' s seats, respectively, but flows toward the rear seats, at the time of ventilation of the vehicle using the windows. Accordingly, although the operator or the passenger of the front seat opens the front window, the operator or the passenger is unable to feel a particular ventilation effect.
Accordingly, since an air ventilation system such as an air-conditioner should be run for a comfortable environment in the vehicle, energy consumption becomes large.
In the meantime, a ventilation device named a 'sun roof may be mounted on the ceiling of a vehicle in order to solve the above-described problem. But, even in the case of the ventilation device such as a 'sun roof, the air flows toward the back seat of the vehicle.
