Prior to the description, components having the same configuration are denoted by the same reference numerals as those in the first embodiment. In other embodiments, configurations different from those of the first embodiment will be described do.

Hereinafter, a humidifying air purifier according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a schematic view of a humidifying air cleaner according to a first embodiment of the present invention, FIG. 3 is a side view of FIG. 2, FIG. 4 is a plan view of the adsorption disk of FIG. 2, to be.

2 and 3, the humidifying air purifier according to the first embodiment of the present invention includes a housing 10, a suction disk 20, and a discharge unit.

The housing 10 includes an upper housing 11 and a lower housing 12, and a water tank 13 in which water is stored is installed in the housing 10.

The upper housing 11 has a suction port 11a through which external air is sucked to the side and an outlet port 11b through which the internal air is discharged.

A blowing fan 14 is installed on the side of the discharge port 11b to form an air flow which sucks the outside air and is discharged to the discharge port 11b.

In the present embodiment, the air blowing fan 14 is used to suck the air stream from the side and discharge it upward. However, another configuration capable of forming the air flow upward from the side may be used.

A plurality of suction discs 20 are arranged on a rotating shaft 21 installed on the lower housing 12 so as to rotate at both ends thereof along the axial direction and are rotated in a state where a part of the water stored in the water tank 13 is locked .

4, the adsorption disk 20 is made of a nonconductive material such as plastic, and a thin metal film is formed on the edge 20a of the adsorption disk 20 to improve the grounding performance .

Further, the surface of the adsorption disk 20 is subjected to a hydrophilic surface treatment, and even if fine dust is adsorbed, it can be easily washed down. Thereby, no separate cleaning means for cleaning the adsorption disk 20 can be provided.

The discharge unit is a discharge electrode including a metal fiber or a carbon fiber at the end thereof. The first discharge unit 31 and the second discharge unit 32 are disposed on both sides of the rotation axis 21 of the adsorption disk 20 Respectively.

As shown in Fig. 5, the distal end of each discharging portion is disposed adjacent to the edge of the adsorption disk 20 so as to be spaced apart from the adsorption disk 20, discharges when a high voltage is applied, .

At this time, the first discharge unit 31 and the second discharge unit 32 may be applied with a high voltage of a single polarity or a high voltage of a polarity opposite to the first voltage.

When a high voltage of a single polarity is applied (unipolar charge), the intake air particles are charged to have the same polarity as the applied high voltage

Further, when a high voltage of opposite polarity is applied (positive charge), particles of the intake air are charged to have a (+) polarity and a (-) polarity.

Hereinafter, the operating state of the humidifying air cleaner will be described. 6 is an operational state diagram of the humidifying air cleaner according to the first embodiment of the present invention.

Referring to FIG. 6, when power is applied to the humidifying air cleaner, the water film A is formed on the surface of the adsorption disk 20 while the rotation shaft 21 rotates. In addition, air is sucked into the housing 10 by the blowing fan 14.

At this time, a high voltage of a single pole is applied to each discharging portion so that the particles of the intake air are charged to either the (+) polarity or the (-) polarity, and the charged particles are adsorbed on the adsorption disk 20.

That is, a high electric field is formed between each discharge portion and the adsorption disk 20, so that charged particles can be adsorbed on the adsorption disk along the electric field.

As a result, the adsorption performance of contaminants in the air can be improved as compared with an air filtering apparatus without a conventional discharge unit.

Further, the gap between the adsorption discs 20 can be secured more widely, and the number of adsorption discs 20 can be remarkably reduced as compared with the prior art, thereby reducing the manufacturing cost.

On the other hand, when the foreign substance (a) is adsorbed on the water film (A) formed on the surface of the adsorption disk (20), part of the water (A) falls on the surface of the adsorption disk And some of them may be rotated while attached to the surface of the adsorption disk 20. [

The foreign substance a adsorbed to the adsorption disk 20 is washed while being immersed in water when the adsorption disk 20 is rotated. At this time, since the surface of the adsorption disk 20 is surface-treated with hydrophilicity, Can be done completely.

The air from which the foreign substance (a) is removed moves to the upper end of the housing 10 and is discharged to the outside through the discharge port 11b.

Figs. 7 and 8 are operational states when high voltages are applied to the respective discharging parts and the opposite polarity to each other. 7 and 8, a high voltage of positive polarity is applied to the first discharger 31 and a high voltage of negative polarity is applied to the second discharger 32.

When a high voltage is applied in this manner, the particles of the intake air are charged to one of the (+) and (-) poles, a part of which is adsorbed to the adsorption disk 20, ≪ / RTI >

When the particles of the intake air are charged with (+) polarity and (-) polarity, the charged particles that are not adsorbed to the adsorption disk 20 and are discharged to the room are bonded by the attraction force of each other, do. When the particles are re-introduced into the housing 10, the size of the particles is larger, so that the adsorption can be easily performed.

That is, as shown in FIG. 8, a particle (b) having a (+) pole is bonded to a particle (c) having a (- . The particles (d) that are grown in association with each other can be more easily adsorbed on the adsorption disk 20 due to their size when re-inhaled into the housing 10.

Through the operation as described above, it is possible to completely discharge and discharge the foreign matter a including fine dust and the like of the air sucked from the outside.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
