Description

Easy-to-clean duct air purification system {Easy-to-clean duct air purification system}

The present invention relates to an air supply and exhaust duct air purification system that is easy to clean, and more particularly, one side of a supply and exhaust duct is exposed indoors to match the ceiling surface, but the exposed surface is detached from the duct. The interior can be cleaned periodically, and a pre-filter is installed inside the duct to filter the air once more, and to improve the indoor air quality by periodically cleaning the air supply and exhaust duct air purification system that is easy to clean.

In general, a forced supply and exhaust system is used so that indoor air is discharged to the outside and outdoor air is forcibly circulated to the room so that the room is not sealed. A total heat exchanger (total heat exchanger) is used as a means to reduce heat loss in the forced supply and exhaust system. When the indoor air is discharged to the outside, it is first heat-exchanged with the discharged indoor air, and then the outdoor air is brought to the room. As a supply method, indoor air is discharged to the outside and at the same time, in the process of inhaling outdoor air and discharging it to the room, heat exchange with each other, thereby adjusting the temperature of the outdoor air introduced into the room to bring it closer to the indoor air.

The total heat exchanger is fixed inside the veranda or indoor ceiling, and the air supply duct and exhaust duct are piped into the ceiling, and a number of air supply and exhaust ports are exposed to the ceiling. It is necessary to clean it by piled up, but these ducts are built into the ceiling, so there is a disadvantage that it is not easy to clean.

Conventional Utility No. 440344 is to expose the duct to the outside, and by forming a number of ducts in a slim double stacked structure that can achieve both supply and exhaust air, minimizing the space ratio and installation cost to be assembled on the ceiling and installation process An exposed duct structure for an indoor ventilation system has been proposed that shortens the installation period and increases convenience according to the simplification of the system.

However, the conventional practical duct is not a detachable structure capable of cleaning the inside of the duct even if it is exposed to the outside of the ceiling, so foreign substances and dust accumulated inside the duct are discharged into the room as it is, thereby degrading the indoor air quality. In addition, since the duct protrudes to the outside, there is a problem such as becoming an obstacle to the interior of the room.

The inventors of the present invention have previously applied for a system for purifying an air supply and exhaust duct that is easy to clean in view of the problems of the prior art as Patent Application No. 10-2019-0038259.

An object of the present invention is to improve the prior application of the present inventors, in which one side of the air supply and exhaust duct is exposed indoors to match the ceiling surface, but the exposed side is detached so that the inside of the duct can be periodically cleaned. In addition, a pre-filter is installed in the duct to filter the air once more and periodically clean water, so it is possible to reuse and to improve the indoor air quality and to provide an easy-to-clean air supply and exhaust duct air purification system.

To this end, the present invention removes the ceiling finishing material in the position where the supply air supply duct and the exhaust duct separated from each other are to be installed in a straight line, and a supply plate and an exhaust plate to be placed in the removed position are provided; An air supply cover and an exhaust cover are provided that are inserted into the ceiling through the removed position of the ceiling finishing material, and the air supply cover and the exhaust cover are composed of the air supply duct and the exhaust duct by sealing an open bottom with the supply and exhaust plate. Become; A plurality of ventilation holes are perforated in the supply plate and the exhaust plate, so that the outdoor air supplied from the supply passage is widely spread into the room along the ventilation hole of the supply plate, and the indoor air flows into the exhaust cover through the ventilation hole of the exhaust plate. In the air supply and exhaust duct air purification system for easy cleaning exhausted to the outside, wherein the ceiling finishing material is composed of a plurality of tex so that the tex at the place where the air supply duct and the exhaust duct are to be placed is removed from the tex bar; The supply plate and the exhaust plate are configured in a plurality of the same size as the tex or are configured integrally; The air supply cover and the exhaust cover have flanges formed on both sides of each lower end, so that the tex is removed and fastened to the underside of the tex bar exposed to the outside with screws; The supply plate and the exhaust plate are screwed to the tex bar from the bottom surface of each flange so as to be flush with the tex that has not been removed; A plate-type pre-filter covering the ventilation hole is detachably provided on the supply plate or the exhaust plate, and is embedded in the air supply cover or the exhaust cover, and the pre-filter can be reused through water cleaning.

According to the present invention, when the ceiling finishing material is tex, a porous supply plate and an exhaust plate are provided with the same size as tex. If it is composed of gypsum board or finishing board, not tex, a place where the supply and exhaust plates are to be placed is perforated, and the supply and exhaust plates are coupled to the perforated positions. In addition, these supply and exhaust plates cover the supply air supply cover and the exhaust air cover on the upper surface to constitute an air supply duct and an exhaust duct. Therefore, the air supply cover and the exhaust cover enter the inside of the ceiling, and the air supply plate and the exhaust plate serve as a ceiling finishing material in the same plane as the tex or finishing plate.

Therefore, since the air supply plate and the exhaust plate are installed in a long line, the air flow is uniformly distributed over a large area and is not concentrated in one place, so that the interior can be made comfortable. In addition, during the indoor air supply and exhaust process, dust, etc., adhere to the inside of the duct due to the humid air. When the supply and exhaust plates are removed, the air supply and exhaust covers are exposed. Therefore, foreign substances on the surface can be regularly removed. You can increase it.

In addition, since the air supply duct and the exhaust duct can be easily equipped with a pre-filter, the air can be filtered once more, and the water can be cleaned periodically, so there is an advantage that the room can be made comfortable if repeatedly reused.

It is fixed to the bottom of the cover 22. In the above, the supply plate 10 and the exhaust plate 20, the air supply cover 12 and the exhaust cover 22 may be composed of a plurality or each may be configured integrally as in other embodiments of the present invention.

A plate-shaped pre-filter 30 is incorporated in the air supply cover 12, and the pre-filter 30 is also incorporated in the exhaust cover 22. The pre-filter 30 filters lint, hair, and large dust, and can be used semi-permanently because it can be washed with water and there is no performance degradation even when used for a long time.

The pre-filter 30 is detachably adhered to the surfaces of the supply plate 10 and the exhaust plate 20 and is embedded in the supply cover 12 and the exhaust cover 22, and in the total heat exchanger 50 Since the supplied outside air flows into the room through the ventilation hole 11 of the pre-filter 30 and the supply plate 10, dust is firstly filtered. In addition, indoor air passes through the pre-filter 30 in the process of flowing into the exhaust cover 22 along the ventilation hole 21 of the exhaust plate 20.
