Description

{AIR CLEANER USING WATER}

The present invention relates to an air purifier using water, which is capable of sucking outside air, contacting the water with the water, moving the mixture into the circular filter, and discharging the pollutant-free air to the pores formed in the circular filter by centrifugal force .

More specifically, the air that is sucked into the air cleaner and primarily filtered at the suction port is moved to a circular filter together with the water in the receiving space, and the centrifugal force generated by rotating the rotating column and the circular filter removes contaminants And air discharged through the secondary filtration through the pores of the circular filter to discharge the purified air and the water vapor together.

Further, the present invention is characterized in that the filter cover is provided on the uppermost surface of the filter cover to filter the filter in a tertiary manner.

In addition, the present invention includes a circular filter and a filter cover which are easily detachable and removes contaminants from the air inside the air cleaner.

Generally, an air purifier mainly purifies air by filtering and adsorbing contaminants in the air by using a dry filter made of fibers mainly made of glass or cellulose.

However, in the case of air purifiers using such a filter, pollutants such as dust accumulate in the filter inside the filter for a long period of time, and the ability to purify the air is reduced.

In addition, since the particle size that can be removed depends on the type of the filter, it is difficult to remove contaminants in the air through the filter when fine particles or noxious gas smaller than the particles of the filter are contained in the air. Various studies have been conducted to improve the problems of the purifier.

On the other hand, in the case of a wet type air cleaner using water instead of a filter using fibers, Patent Document 10-2007-0104719 discloses an air cleaning apparatus using centrifugal force (see FIG. 7).

The technique described above relates to an air purification apparatus for purifying the air of a multipurpose facility. More particularly, the contaminated air passes through the spinneret, injects water at the inlet side of the spinneret, rotates the rotating shaft through the center of the spinneret, the contaminants in the contaminated air adhere to the water, So that the pollutants in the air introduced from the inlet side of the rotary kiln are removed from the rotary kiln, and then the purified air is discharged to the outside of the rotary kiln So that contaminated air is introduced from the outlet side of the rotary kiln and is discharged to the inlet side of the rotary kiln after being removed from the rotary kiln, and the air having centrifugal force capable of cleaning the contaminated air flowing in both directions And a purification device.

However, since the above-described technique removes contaminants in the air using a method of spraying water into the air sucked into the air purifying device, the air may not be sufficiently purified when water is not sufficiently sprayed.

In addition, by opening the front and rear sides of the air purifying device and sucking in air, foreign substances other than air are also introduced, thereby causing malfunction and safety accident of the air purifying device. Since the pollutant does not remain in the air purifying device, However, it is obvious that there is a need to clean the inside of the air cleaner later due to the water spray due to the water sprayed from the inside of the spinneret and the pollutants adhered to the inner wall of the spinneret.

Accordingly, it is an object of the present invention to solve the above-mentioned problems and to provide an air purifying device capable of easily removing and installing the filter inside the air purifier, It is required to develop an air purifier having a function of removing pollutants.
