Description

VENTILATION CLEAN AIR SUPPLY SYSTEM

The present invention relates to a ventilation clean air supply device.

In general, houses, apartments, or offices are designed and constructed in a closed structure to improve cooling, heating and noise blocking functions, so that indoor or outdoor air cannot circulate indoors and outdoors, so fine dust or There is a problem in that fine dust (hereinafter referred to as "fine dust") accumulates indoors.

Such fine dust is transported to the lungs by respiration, and air is expelled from the lungs to the outside world. In this process, fine dust continues to accumulate indoors and in the body, ultimately harming human health.

In addition, indoor smoke generated during food cooking, toilet odor, cigarette smoke, and harmful exhaust gases such as carbon monoxide, carbon dioxide, and rust (hereinafter referred to as “fine dust”) are generated. There is a problem that various diseases occur due to the generated fine dust.

In particular, in recent years, fine dust caused by various emission sources has become serious enough to become a social problem.

In the past, although ventilation is required to prevent the inflow of severe external dust or polluted air, there are cases in which the window cannot be opened at all. Although conventional air purifiers have been developed to purify indoor air, in general, indoor air containing fine dust from the outside is sucked in, purified, and then discharged back into the room. By purifying only air, the purification ability was lowered, and there were disadvantages in that there were many dead spaces in which the indoor space was not purified by the air purifier.

In addition, fatal problems such as the inability to purify indoor air pollution caused by yellow sand and the like have been pointed out.

This is because there is a limit to removing particulate carbon monoxide, nitrogen oxides, carbon dioxide, etc. by dust collection and adsorption methods when the room is sealed, and hardly purifies the air during ventilation.

The air purification method of such an indoor space currently consists of a dust collecting filter, an electric dust collecting filter, an adsorption filter, an anion generator, etc., but in this way, only dust, some odorous substances, organic compounds, etc. can be removed. There is a problem that a person indoors also inhales dust, some odorous substances, organic compounds, etc. through breathing at the same time.

The indoor air environment generally has poor air ventilation and has a higher concentration of carbon monoxide, volatile organic compounds, carbon dioxide, nitrogen oxides, dust, etc. than the outdoor air environment due to pollutants generated from cooking, smoking, and painting materials for furniture and clothing. is high in reality.

General household air purifiers installed to improve the indoor air environment try to improve it through dust collection and adsorption methods, or to remove dust and odors through methods using catalysts or ozone, but the indoor air environment has a high level of pollution. Therefore, the equipment is complicated and the quality of the purified air is low.

In addition, the adsorption method exhibits superior performance at the beginning, but when the adsorption amount of the adsorbent is exceeded, the air quality is rather deteriorated, and when regular replacement is not performed, there is a problem that the air quality is further deteriorated, such as microorganisms breeding on the filter layer.

In addition, the air inlet 110 may be mounted in one of the first and second inlet mounting grooves 121 and 122 according to a location where the ventilation clean air supply device 10 is installed. In addition, the inlet dummy 101 is mounted in the inlet mounting groove to which the air inlet 110 is not mounted so that external or indoor air does not flow into the interior of the first housing 100 , thereby blocking the hole. . In addition, since the air inlet 110 is mounted by selecting any one of the first inlet mounting groove 121 and the second inlet mounting groove 122, the air inlet can be freely installed according to the structure of the building or the location of the window. (110) can be selected.

Referring to FIG. 4 , the damper unit 130 adjusts the blocking state of the indoor air inlet 111 or the outdoor air inlet 112 between the indoor air inlet 111 or the outdoor air inlet 112 so that indoor air or The outdoor air intake can be adjusted. In addition, the damper unit 130 may be detachably formed and disposed adjacent to a position where the air inlet unit 110 is mounted among the first and second inlet mounting grooves 121 and 122 .
