BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air duct structure of a building, and more particularly, to an air duct structure having a vertically formed air duct for discharging contaminated air generated in an apartment, a multi- So that the purified air can be discharged from the building. At the same time, the indoor air flowing through the inside of the air duct is smoothly flowed to improve the exhaust speed, thereby reducing power consumption. Further, And the air duct function is greatly improved by reducing the noise and condensation phenomenon generated when the indoor air of the indoor air is exhausted.

Generally, in an apartment, a multi-family house, a commercial building, and the like, an air duct is generally a compartment space formed vertically on the inside or outside wall of a building for discharging polluted air discharged from each household or an underground space or a cooking chamber, And an air passage for naturally sucking and forcibly blowing indoor air by a non-powered ventilator installed at the top (roof) or by an electric fan installed independently for each generation.

The air discharge capacity of the air duct depends on the duct resistance (duct resistance) and the degree of airtightness of the duct depending on the degree of roughness of the inner wall surface of the duct. That is, the air discharging ability of the air duct becomes rougher as the inner wall surface becomes rough, the resistance of the air duct becomes larger, and the air discharging ability of the air duct is lowered as much as the air duct space is not hermetically sealed.

In order to solve such a problem, air ducts of various structures have been introduced, for example, Patent Document 1 Registration Utility Model No. 20-0446695 having a structure for improving airtightness of air ducts, Patent Document 2 having a duct frame fixing structure of a diffuser for air conditioning that allows the frame to be easily assembled to the ceiling can be easily assembled. Noise is generated in the duct to suppress noise generated in the interior of the air duct or the regenerative power generator 20-0450750 And Patent Document 3 (Japanese Patent Application Laid-Open No. 2017-116837) which discloses a device.

But. The above Patent Document 1 improves the air-tightness of the air duct to improve the air-discharging ability, but it does not filter pollutants containing foreign substances exhausted through the duct, And a frame containing a filter medium at the inlet of the air duct can be installed as a means for filtering contaminants contained in the indoor air passing through the inside of the duct to remove the air discharged from the filter medium. It is possible to filter the contaminants by filling the filter medium inside the air duct. However, this also prevents the flow of the air due to the filter medium filled in the air duct, and it is difficult to replace the filled filter medium The problem is pointed out.

Patent Document 2 discloses a duct frame fixing structure of an air conditioner diffuser which can easily fix a duct frame to a ceiling without using a separate screw, and it is an object of the present invention to provide a duct frame fixing structure for an air conditioner, The structure of the air duct is not sufficiently improved to improve the function of the air duct. Patent Document 3 can attenuate the noise generated by the air flowing through the inside of the air duct by the silencer, There is a problem that the technology for reducing the technical structure and the removal of the foreign matter is not disclosed and the air flow is obstructed by the silencer installed in the duct to degrade the exhausting ability.
