Description

Air cleaner {AIR CLEANER}

The present invention relates to an air purifier, and more particularly, to an air purifier capable of effectively removing contaminants such as fine dust contained in the air by contacting with a fluid.

In general, an air purifier is a device that removes contaminants such as fine dust, various harmful gases, germs, mold, and viruses from the air and discharges purified air.

Such air cleaners are classified into dry cleaners and wet cleaners according to the method of removing contaminants from the air, and the dry cleaners are divided into an electrostatic precipitator type and a filter filtration type.

The electrostatic precipitating method has the advantage that no filter replacement is required, but it has the disadvantage that when the contaminants are accumulated on the electrostatic precipitating plate, the purifying ability is reduced and the removal performance of contaminants such as fine dust is reduced.

Meanwhile, the filter filtration method is widely used to filter and treat fine dust, such as dust contained in the air, using a filter made of a non-woven fabric or filter paper in such a way that air flows between filters to filter contaminants from the air.

However, since the air purifier using the filter degrades the filtration performance by attaching foreign substances such as dust to the filter as the usage time elapses, the user must periodically clean the filter or replace it with a new one.

Therefore, the air purifier using a filter made of non-woven fabric or filter paper is also pointed out as a problem that it takes a lot of manpower and cost to manage because the filter needs to be periodically cleaned or the filter frequently replaced.

Filter performance depends on the through-hole through which air passes. In addition, when the filter is not clean, there is a fear that various bacteria may multiply, which may cause a problem of supplying air contaminated with bacteria.

On the other hand, Korean Patent Publication No. 10-2018-0001395 discloses an air purifier that removes contaminants by contact with water by passing contaminated air therein. This air purifier is to remove contaminants in such a way that contaminants such as fine dust are adsorbed into the water particles by contacting the water particles with the air to be introduced or precipitated in the water tank.

However, the air purifier according to Patent Publication No. 10-2018-0001395 has a problem that fine dust that does not come into contact with water comes out of the air purifier.

And, Japanese Patent No. 2998022 discloses an apparatus for removing fine contaminants such as fine dust using a water filter. The apparatus disclosed in Japanese Patent No. 2998022 is a device that uses water as a filter to remove contaminants by trapping them in water when air containing contaminants passes through the water.

However, the apparatus disclosed in Japanese Patent No. 2998022 has a limitation in that it cannot be used as a household air purifier because a large noise is generated when the air bubble rises over water due to the large size of the air bubble.

Can be configured without limitation.

For example, the noise attenuation mechanism 7 is composed of a disc structure in which a bubble shattering slit is formed between and divided into a plurality as shown in FIGS. 2 and 5 to be located on the water surface accommodated in the main tank 1 so that the main tank is located. It can be coupled to the inner peripheral surface.

As described above, when the noise reduction mechanism 7 is disposed close to the water surface, air bubbles rising toward the water surface are once again crushed to attenuate noise generated on the water surface.

Hereinafter, the operation of the air purifier according to the first embodiment of the present invention will be briefly described.

8 is a view for explaining the operation of the air purifier according to the first embodiment of the present invention.

The air purifier according to the first embodiment of the present invention is only to be used for the purification of polluted air. As shown in FIG. 8, water is introduced into the main tank or inserted into the water by a predetermined depth to form the inner drum 3 and the outside. Let the drum 4 immerse in water. At this time, the water depth is adjusted so that floating air can be introduced into the upper space of the main tank 1 and discharged through the air outlet 13.

In this state, when the driving motor 5 is operated, while the rotational force is transmitted via the rotation shaft 63, the pressure regulating mechanism 6 rotates and the internal drum 3 mechanically fixed to the pressure regulating mechanism also rotates. It will perform.

In this state, when the blower configured as the air intake means 2 is operated, contaminated air is introduced into the inside of the inner drum 3 through the air intake pipe 25. At this time, the static pressure generated by the normal blower can not blow contaminated air into the interior of the drum 3 while pushing water having a density difference of 800 times or more with the air, but the pressure is corrected by the pressure regulating mechanism 6. By this, it is possible to easily perform the blowing operation.

More specifically, when the fluid discharge blade 61 of the pressure regulating mechanism 6 is rotated at high speed by the rotational force of the driving motor 5, the water inside the internal drum 3 is pushed outward, and most When water is discharged and the internal pressure is lowered, contaminated air is easily introduced, so that a smooth blowing action is possible.

On the other hand, when the contaminated air supplied from the air intake means 2 flows into the inner drum 3 by the action of the pressure regulating mechanism 6 as described above, the circular first through hole 33 is formed by the pressure-transmitting force. Primary crushing while passing, the primary crushed air bubbles are finely crushed while passing through the second through hole 43 of the square shape. In particular, since the inner drum 3 in which the first through hole 33 is formed is rotated, it performs a function similar to a cutter in the process of passing air bubbles through the first through hole 33 and the second through hole 43. The effect of crushing air bubbles more finely is exerted.

In addition, a plurality of air bubbles ejected to the outside of the second through-hole 43 is raised by buoyancy, and the outer surface of the air bubbles is in contact with water during this ascent process, thereby removing the pollutants. At this time, the smaller the size of the air bubble based on the contaminated air of the unit volume, the larger the contact area with the water becomes, so the purification efficiency can be further improved. In addition, the size of the air bubble has an advantage in that the smaller the particle size, the less the noise generated as the air bubble bursts from the water surface.

Thereafter, when air bubbles floating in the water of the main tank 1 are close to the water surface, the crushing action is performed once again at the bubble slit portion of the noise damping mechanism 7 to minimize noise generation on the water surface. When used as an air purifier in an office or the like, there is an advantage that does not cause discomfort.

On the other hand, the air purifier according to the present invention can increase the rotational speed of the inner drum 3 when the rotational speed of the drive motor 5 is increased during the crushing process of the air bubbles, as described above, thereby further increasing the size of the air bubbles. Since it can be crushed small, it is possible to efficiently purify the contaminated air by controlling the rotational speed of the drive motor according to various conditions such as the amount of contaminated air or the place of installation.

For example, the air purifier according to the present invention is a fine dust detection means (not shown), a detection means for detecting the rotational speed of a blower (not shown) or a detection means for measuring the flow rate of contaminated air flowing into an air intake pipe (not shown) It is further provided, it is possible to effectively perform the purifying action of the polluted air by increasing or decreasing the rotational speed by controlling the drive motor according to the pollution degree of the air or the flow rate of the polluted air calculated by the detection signal applied from the sensing means.
