Description

Air purifier using water {AIR CLEANER USING WATER}

The present invention relates to an air purifier using water, and more particularly, to an air purifier using water capable of purifying air by contacting air introduced from the outside with circulating water to adsorb contaminants into the water.

In general, an air purifier is a device that filters pollutants or fine dust in polluted air in the process of forcibly circulating indoor air by blowing, and discharges the cleaned air into the room.

Such an air purifier purifies the air by filtering and adsorbing contaminants in the air using a dry filter made of fiber made of glass or cellulose.

However, in the case of an air purifier using such a filter, contaminants such as dust in the air accumulate inside the filter when used for a long time, reducing the ability to purify the air, incurring additional costs due to filter replacement, and replacing the filter There is a problem that maintenance is cumbersome because the external parts of the air purifier must be separated and reassembled after replacing the filter.

Accordingly, in recent years, a wet air purifier using water, rather than a method of filtering and adsorbing pollutants through various filters, has been developed.

The wet air purifier using water as described above is also called an air washer, and generally uses a method of attaching dust by injecting air containing dust into a rotating disk, but the disk has a sufficiently wide surface area There is a problem that cleaning is difficult and there is a concern that the performance of the basic function of an air purifier may be deteriorated because a plurality of them are installed at very narrow intervals.
