Description

[0001] WET TYPE AIR CLEANER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet type air cleaner capable of purifying dust or contaminants in air introduced using water vapor.

Generally, the air purifier removes dust or contaminants contained in the air while passing through the filter, and purifies the air in the process of forcibly sucking and discharging the outside air.

Conventional air cleaners are classified into a filter type and an electric dust collecting type. The filter type filters dust and contaminants in the air as they pass through the filter. In the electric dust collecting type, dust and contaminants in the air are adsorbed to the dust collector by an electric field.

In recent years, environmental pollution due to increase of fine dust such as automobile exhaust gas and dust from China has reached a serious level, and an air purifier using water has been proposed.

As one type of air purifier using water as described above, wet air cleaners using water as a filter are typical.

That is, the wet air cleaner described above is constituted of a lower case in which water is dewatered and a plurality of individual discs are placed, and an upper case having an inlet at an upper portion thereof, a discharge port at a side surface thereof, and a blower fan thereunder. According to this structure, air introduced into the air blowing fan is brought into contact with a plurality of individual disks supported and rotatable in a lower case in which water is drained, and then discharged to a discharge port formed in a side surface of the upper case. So as to purify the air.

However, in the wet air cleaner having the above-described structure, the incoming air is immediately discharged to the discharge port after coming into contact with the water particles buried in the individual disk, so that the contact time with the individual disk is short and the inflow air is saturated, There is a problem in that a considerable amount of air is discharged without being in contact with the individual discs, thereby deteriorating the air purification effect.

In addition, a plurality of individual disks of the wet air cleaner are provided in a tightly closed space and are maintained in a state of being contaminated with water stored therein, in addition to difficulties in maintenance such as watering and washing, There is a continuing problem.
