Description

Air Purifier {Device for purifing contaminated air}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier, and more particularly, to absorb contaminated air by a fan operated by a motor into a reservoir containing purified water and to install dust under the fan by an impeller mounted under the fan and vertically rotating in water. The present invention relates to an air purifier configured to discharge only purified air to the atmosphere through the exhaust hole while allowing soot such as soot to be sucked into the water and dissolved or precipitated.

In recent years, as the industry develops, air pollution, which is seriously polluted, is not only severe, but also contaminated by air, dust, smoke, and tobacco smoke in hospitals, laboratories, food galleys, offices, department stores, and hotel lobbies. This is more severe and this causes a problem that causes various respiratory diseases or skin diseases.

In order to solve such a problem, the air was sterilized or purified by a filtering method, an electrostatic precipitating method, or an ultraviolet ray method.

Here, the filtering method is a method of sucking contaminated air using a suction fan and then filtering the filter body and discharging the air through a grill.Hepa filter (HEPA FILTER) By adsorbing dust and then removing gas and odor through a carbon filter.

However, this filtering method has a disadvantage in that very fine dust particles cannot be filtered and thus have a poor sterilization ability, and also cause a secondary pollutant caused by the filter.

In addition, the electrostatic precipitating method allows the polluted air to pass through the positively charged ionization line so that the contaminating molecules are positively charged and then strongly adsorbed to the negatively charged dust collecting plate. Since the current flowing in the high pressure portion is changed and there is no change in the air volume, the dust collection efficiency is lowered, and there is a disadvantage that the gaseous substance cannot be removed.

In addition, the ultraviolet method sterilizes dust particles by using a sterilizing line of 253.7㎛ in ultraviolet light, but its wavelength is limited, so it is easy to sterilize around the UV lamp, but sterilization ability is remarkably deteriorated when it is out of a certain distance. There was a problem that the processing was not smooth.

Therefore, the present invention improves the drawbacks of the conventional air purifier as described above, and absorbs and removes the pollutants in the air, such as solids, gases, liquids, and odors, as well as water. It is to provide an air purifier to discharge.
