Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air filter system for an air duct of a vehicle having a multi-roll type air filter,

The present invention relates to an air filter system for an air duct of a vehicle having a multi-roll type air filter, and more particularly, to an air filter system for a multi-roll type air filter, which comprises a plurality of roll-shaped air filters each capable of filtering different- It is possible to greatly improve the filtration efficiency by filtering the minute size foreign substances in the order of size according to the size by each roll filter and to change the replacement time of the air filter having high pollution degree and the air filter having low pollution degree, The present invention relates to an air filter system for an air duct of a vehicle having a multi-roll type air filter having a structure capable of reducing the size of the air filter.

Generally, the air duct of the vehicle is equipped with an air filter for filtering foreign matter contained in the outside and inside air flowing into the air duct.

Such foreign matter remains on the conventional air filter, and the residue adheres to the air filter to create a very favorable environment for the propagation of noxious bacteria and fungus. In this environment, The fungus passes through the air filter, flows into the car through the air duct, and is sucked into the human body through the respiratory system of the occupant, causing various diseases.

In order to solve the above-mentioned problems, conventionally, a filter paper having an antibacterial function is used to manufacture an air filter, thereby suppressing the propagation of noxious bacteria and mold bacteria in the residue filtered on the air filter.

However, in the conventional antimicrobial method, since the antimicrobial substance coated on the filter paper of the air filter is exhausted in a short period of time, the antimicrobial function is extinguished until the air filter is exchanged, so that the propagation of harmful bacteria and fungi is suppressed In addition, the air filter is not changed according to the proper timing, so that the harmful bacteria which are harmful to the human body such as fungi propagate on the air filter, so that odorous air contaminated by the bacteria is introduced into the vehicle, There was a problem that it went crazy.

The Applicant has made various attempts and efforts in order to solve such a conventional problem. As a result, it has been necessary to invent an air filter system for an air duct of a vehicle having a roll type air filter, (Hereinafter referred to as "the earlier application") to the Korean Intellectual Property Office (KIPO).
