Method and device for promoting efficiency of purifying in-vehicle air

Abstract

The invention relates to a method for promoting the efficiency of purifying in-vehicle air. The method comprises: providing a central air outlet mechanism provided with at least one air outlet assembly, and introducing first airflow from an air conditioning system to the inside of an automobile after the first airflow enters the air outlet assembly; and providing an air purification device, introducing the air from the inside of the automobile into the air purification device to form second airflow and leading the second airflow to the air outlet assembly, wherein the flow velocity of the second airflow in the air outlet assembly is increased by the first airflow, so as to accelerate air circulation in the automobile. The invention further relates to a device for promoting the efficiency of purifying the in-vehicle air. According to the method provided by the invention, the velocity of the purified second airflow from the air purification device in the air outlet assembly is increased by virtue of the first airflow from the air conditioning system, so that the circulation of the air blown out of the air outlet assembly in a whole cabin is accelerated, and the efficiency of purifying the in-vehicle air is improved.

Description

technical field [0001] The invention relates to air purification in a vehicle, and more particularly to a method and a device for improving the efficiency of air purification in a vehicle. Background technique [0002] With the development of the economy and the improvement of people's living standards, people pay more attention to the safety of the car itself while pursuing the convenience brought by the car lock. Among them, the air quality in the car has become another key indicator of car safety. [0003] In the prior art, the air purification methods for the internal circulation of the air in the car are mainly divided into two types: one is active air purification, mainly represented by negative ions, photocatalyst technology, etc.; the other is passive air purification, mainly form through a sieve. These two methods have their drawbacks. Among them, active air purification is mainly represented by negative ion and plasma technology. Although this active purification ...

Problems solved by technology

Among them, the passive air purification device arranged in the armrest of the central console is often provided with air inlets and air outlets at the longitudinal ends of the armrest, so that the blown purified air is either blown to the front row space or to the rear row space, so that The purification area per unit time is limited, which also affects the purification efficiency; and because the distance between the air inlet and the air outlet arranged at both ends of the armrest is small, the motor arranged between the air inlet and the air outlet emits The noise is amplified by the air inlet and outlet, causing discomfort to the passengers in the car

The purified air blown out by the passive air purification device arranged on the upper surface of the instrument panel diffuses from the front row space to the rear row space. Although the purification area per unit time is expanded, the purification efficiency is still relatively low due to the limitation of its own motor power. , and the arrangement on the upper surface of the instrument panel also affects the appearance of the car interior

[0005] For the air purification method under the external circulation of the air in the car, it is usually to add a filter screen to the air conditioning system, but this purification effect is often affected by the filter screen itself. When the filter screen is relatively dense, the purification effect is better. The air volume will decrease accordingly; on the contrary, when the filter is relatively loose, the air volume will increase, but the purification effect will decrease accordingly
