As shown in Figure 1, the indoor air purifying apparatus according to a preferred embodiment of the present invention, a purifying unit 10 for discharging the indoor air to be discharged to the outside, and purifies the indoor air to return to the indoor circulation It consists of a circulating purifying unit 20, and an air supply unit for sucking contaminated indoor air to selectively supply to the discharge purifying unit 10 and the circulating purifying unit 20.

The exhaust purifying unit 10 includes an exhaust fan 15 that discharges purified air driven by an ozone generator 11, a plurality of first to third filters 12, 13, and 14 and a motor to the outside. ), And an exhaust passage 16.

The ozone generator 11 is a device for purifying air by the generated ozone after generating ozone, which is well known and thus will not be described in detail. The ozone generated by the ozone generator 11 is supplied to and mixed with air just before air enters the exhaust purification unit 10. That is, as shown in Figure 1, ozone is preferably supplied through a separate passage (11a) into the first branch pipe 34 of the air supply unit to be described later.

In an embodiment of the present invention, an electrostatic filter is used as the first filter 12, a nano filter is used as the second filter 13, and activated carbon is used as the third filter 14. The filter is used.

The electrostatic filter as the first filter 12 utilizes electrostatic collection by electric field in addition to the inertial, gravity, blocking, and diffusion collecting mechanism known as a mechanical collecting mechanism in which particles in the air stream are collected by fibers.

That is, the particles suspended in the air generally contain a large number of particles charged with (-) or (+), and these charged particles are strongly adsorbed by the electrostatic filter. In addition, among the suspended particles, particles that are not neutrally charged also generate dielectric polarization on the particles due to an electric field caused by the electrostatic filter, which causes attraction between the particles and the electrostatic filter and is adsorbed by the electrostatic filter. For this reason, the electrostatic filter using the electrostatic collection shows higher collection efficiency for all particle diameters than the mechanical collection filter.

In addition, the nano filter as the second filter 13 may be used as any type of nano filter known as being capable of separating various contaminants by utilizing nanotechnology, and thus will not be described in detail.

According to the embodiment of the present invention, as the cylindrical filter 21, a nano filter having permanent static electricity is used. That is, the cylindrical filter 21 is made by winding a charged polymer synthetic resin film in a cylindrical shape (see FIG. 3). The air passes through the cylindrical filter 21 in the longitudinal direction, and fine dust in the air at this time. Contaminants such as bacteria, bacteria, mite droppings, pollen, etc. are collected and attached to the surface of the film by static electricity. In particular, all living organisms such as bacteria and viruses are polar because they contain water, and thus the cylindrical filter 21 has a very good capturing ability against these bacteria, viruses, and the like.

The cylindrical filter 21 is formed so as to maximize the electrostatic attraction of the electrostatic film layer while extending the residence time by forming an obstacle in the gap through which the polymer resin film is rolled up to allow air to pass zigzag. It is desirable to be. That is, protrusions are formed on the film at a constant pitch, rolled up to secure a space and an area, and the air of contamination and odor is collected in the axial direction by the gap.

In addition, since the cylindrical filter 21 is in the form of a roll, the air is sucked in and discharged in the axial direction, and the pressure loss is significantly low, while maximizing filter collection efficiency. Existing filters inject air in the axial direction and switch the flow in the 90-degree direction while penetrating through the filter mesh and collecting pressure loss.

The circulation fan 22 has a function of cooperating with an intake fan 32 to be described later to inhale, purify the air in the room, and to continuously circulate.

The air supply unit includes a suction fan 32 driven by a motor to suck indoor air through the suction port 31, a duct 33 for transferring indoor air sucked by the suction fan 32, The first branch pipe 34 for branching from the duct 33 to send the indoor air to the purifying unit 10 for discharge, branched from the duct 33 to the circulation purifying unit 20 The second branch pipe (35) for sending, and the branch point of the first and second branch pipes (34, 35) are installed in any one of the discharge purifying unit 10 and the circulation purifying unit (20).
