As shown in fig. 4 and 5, the negative pressure generated by the exhaust fan causes the air in the lower air duct to be sucked in time through the lower air duct to the outlet of the exhaust fan and then discharged, and the automobile air conditioner forms a single streamline in which fresh air enters from the outside of the automobile and then is discharged from the outside of the automobile, and the streamline is shown in fig. 5. The upper air duct sub-air opening and the lower air duct sub-air opening correspond to each other, so that the trend of the streamline of the air is easy to control.
In conclusion, in the whole process from the inflow of fresh air to the exhaust of air from the interior of the vehicle, the upper air duct and the lower air duct of the vehicle utilize the upper air duct sub-air port and the lower air duct sub-air port which correspond to each other and correspond to the comfortable position of a human body at the seat, so that the air is ensured to be exhausted from the corresponding air ports in time after flowing through passengers, and the cross infection caused by the fact that the air flowing through the passengers stays in the vehicle for a long time is avoided. The air-conditioning air purifier realizes the open type single external circulation of air in a vehicle in the process of introducing fresh air to exhaust, so that the air is continuously sucked from the outside, and the freshness of the air in the vehicle is ensured under special conditions such as epidemic situations and normal conditions.
Alternative embodiments: as shown in fig. 6, the lower air duct is changed or switched to be a duct through which fresh air enters the vehicle, and the upper air duct is an air duct through which air is exhausted from the vehicle, wherein the exhaust fan is located at the total air opening of the upper air duct. As shown in fig. 7, according to the rapid increase of the temperature of the feet of a human body in a cold condition, the overall temperature of the human body can be greatly increased, and the comfort of the upper half part of the human body is greatly influenced in a summer heat condition, so that the air conditioner can adopt a heating working condition and adopt an air inlet upper air duct to exhaust air in different working conditions of refrigeration and heating of the air conditioner; in the refrigeration working condition, the upper air duct is used for air intake and the lower air duct is used for air exhaust, so that the comfort of the automobile is improved.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
