Air purifier system for vehicle and purification method of air purifier system

Abstract

The invention discloses an air purifier system for a vehicle and a purification method of the air purifier system. The air purifier system comprises an internal and external circulation module, an air conditioner controller and an air purifier, wherein the air conditioner controller is used for outputting a control signal used for enabling the air purifier to work according to a vehicle air state. The method comprises the following steps: obtaining a current vehicle air state; judging the current vehicle air state, if the current vehicle air state is an internal circulation state, enabling the air purifier to work under the condition that the duty cycle is T1 and the duty ratio is R1, and if the current vehicle air state is an external circulation state, enabling the air purifier to work under the condition that the duty cycle is T2 and the duty ratio is R2, wherein R1 is more than R2, and T1 and T2 are determined by the vehicle air circulation speed. According to the air purifier system and the purification method, the negative duty ratio is increased in the internal circulation state, so that circulation air in the vehicle can be better purified; a relatively large amount of fresh air enters the vehicle in the external circulation state, and at the moment, the duty ratio is reduced, so that the working time of a negative ion generator is shortened, the service life of the negative ion generator is prolonged, and the energy consumption of the vehicle is reduced.

Description

technical field [0001] The invention relates to a vehicle air purifier system and a purifying method thereof. Background technique [0002] During the process of the vehicle from starting to driving, the occupants of the vehicle will open or close the windows and air conditioners. When the window is closed, a relatively closed space is formed in the car, resulting in poor air quality in the car. In order to improve driving and riding comfort, air purifiers are usually used to improve the air quality in the car. A common air purifier is a negative ion generator, and the operation of the negative ion generator is completed manually or by setting a fixed switching rhythm. [0003] During the use of the vehicle, there are two states of internal circulation and external circulation of the air in the vehicle. During internal circulation, the windows are closed, and the air inside the car does not circulate and exchange with the air outside the car, but the air inside the car is...

AI Technical Summary

Problems solved by technology

[0004] Existing technical solutions do not take into account the actual state of the air in the car, but only complete the operation of the negative ion generator manually or by setting a fixed switching rhythm, which has the following disadvantages:

[0005] 1. The duty ratio of the negative ion generator cannot be adjusted well (the ratio of the time when the negative ion generator is on and off)
