Description

Air purifier that rotates liquid to collect pollutants {AIR PURIFIER ROTATING WATER FOR COLLECTING POLLUTANTS}

The present disclosure relates to air purifiers.

This disclosure is derived from a study conducted as part of the Small and Medium Venture Business Entrepreneurship Growth Technology Development (general, R&D). [Task identification number: 1425155278, detailed task number: S3130673, research management specialized institution: Small and Medium Business Technology Information Promotion Agency, research project name: total maintenance cost reduction and sustainable water-filtering air purifier's water exchange automation and airborne bacteria reduction and PM2. 5 Technology development for 95% reduction performance, contribution rate: 1/1, host organization: public corporation, research period: 2021.07.01 ~ 2023.06.30]

As the industry develops, the amount of fine dust in the air is increasing due to air pollution such as industrial dust, automobile exhaust, and yellow dust. As the amount of fine dust increases, the number of days contaminated beyond the recommended standard limits not only daily life but also outdoor activities. When exposed to fine dust for a long time, heavy metals, etc. contained in fine dust are introduced into the human body and adversely affect health. In addition, when ventilation is performed to discharge dust or carbon dioxide scattered due to indoor activities in the home, fine dust in the outside air is introduced and deteriorates indoor air quality, which is more harmful to the health of children and bronchial patients. can have adverse effects.

BACKGROUND ART Various types of air purifiers that collect harmful substances such as dust generated indoors or fine dust introduced from the outside to purify polluted indoor air and discharge the purified air have been developed and marketed.

Among various types of air purifiers, dry air purifiers are configured to purify and discharge fine dust by using a filter for physically filtering fine dust or a tread plate for electrically collecting fine dust, or using both together.

In the case of the dry air purifier described above, the life of the filter decreases as contaminants accumulate in the filter filtration method, and the collection resistance increases as contaminants accumulate in the dust collecting plate in the electric dust collecting method. Therefore, after a certain amount or more of contaminants are accumulated in the filter or the dust collection plate, since the dust cannot be filtered or rather pollutants are discharged, the filter or the dust collection plate must be replaced or cleaned at an appropriate time. In addition, when replacing filters or dust collection plates periodically, users may have an economic burden because additional costs are incurred for replacing filters or dust collection plates. This economic burden could increase exponentially. In addition, when the filter or the dust collecting plate is periodically washed, the user feels the inconvenience of washing and drying the filter or the dust collecting plate. In addition, when the power of the air purifier is cut off, there is a problem in that the collected contaminants are re-scattered because the adsorption performance of the filter or the dust collecting plate is lost.
