Embodiment 1

[0026] The embodiment of the present invention provides an improved device for the vehicle ventilation system, see figure 1 , the improved device is provided for the rear coat rack ventilation hole 1 on the rear coat rack 2 . join figure 2 , the device comprises a ventilation hole cover plate 3, a transmission shaft 4 and a motor 5, the ventilation hole cover plate 3 can cover the rear coat rack ventilation hole 1, and the middle part of one end of the ventilation hole cover plate 3 is connected with the motor 5 through the transmission shaft 4 As a whole, the motor 5 can drive the ventilation hole cover plate 3 to rotate, so that the ventilation hole cover plate 3 covers or leaves the rear coat rack ventilation hole 1 .

[0027] The improved device for the ventilation system of the whole vehicle provided by the embodiment of the present invention can make the vent hole of the rear coat rack in the closed state in the internal circulation mode by setting the vent hole cover ...

Embodiment 2

[0038] An embodiment of the present invention provides a control method for controlling the improved device of the vehicle ventilation system provided in Embodiment 1. The method is as follows:

[0039] When the temperature inside the car is too high, it is necessary to turn on the air conditioner for cooling, generally in the internal circulation mode:

[0040] When the automobile air conditioner is in the internal circulation mode, the motor 5 is started to drive the ventilation hole cover 3 to rotate, so that the ventilation hole cover 3 covers the ventilation hole 1 of the rear coat rack, and the rear ventilation hole 1 of the coat rack is closed;

[0041] When the occupants in the car need to exchange air with the outside environment, press the outer circulation button to select the external circulation mode:

[0042] When the automobile air conditioner is in the external circulation mode, the motor 5 starts to drive the ventilation hole cover plate 3 to rotate, so that ...

Abstract

The invention discloses an improved device for a full vehicle ventilation system and a control method for the improved device and belongs to the field of ventilation systems. The improved device comprises a ventilation hole cover board, a transmission shaft and a motor, wherein the ventilation hole cover board is connected with the motor through the transmission shaft; and the motor drives the ventilation hole cover board to rotate, so the ventilation hole cover board covers or uncovers a ventilation hole in a rear hat and coat stand. By arranging an openable and closable ventilation hole cover board on the ventilation hole in the rear hat and coat stand, the ventilation hole in the rear hat and coat stand is in a closed state under an inner circulation mode, so heat exchange between air in a vehicle and air in a trunk is avoided and unnecessary loss of the refrigeration quantity of an air conditioner is avoided; therefore, energy is saved.

Description

technical field [0001] The invention relates to the field of ventilation systems, in particular to a device for improving the ventilation system of a whole vehicle, which is especially suitable for a three-compartment car. Background technique [0002] The traditional car ventilation system channels include the intake grille of the decorative panel under the front windshield, the fresh air inlet of the air conditioner, the air blowing surface / foot blowing / defrosting air outlet, the ventilation grille of the rear coat rack and the rear ventilation frame at the rear of the car. [0003] In the above-mentioned traditional ventilation system, under the external circulation mode of the automobile air conditioner, the airflow of the whole vehicle flows from the intake grille through the components of the above-mentioned ventilation system in sequence, and finally flows to the rear ventilation frame at the rear of the car to achieve the purpose of ventilation of the whole vehicle; ...
