The present invention relates to an air purifier, and more particularly, to an air purifier for purifying indoor air, by allowing rear suction to purify the air in three directions in various directions, purifying the air and then discharging upwards. will be.

An air purifier is a device that purifies contaminated air and converts it into fresh air. The contaminated air is sucked into a fan to collect fine dust or bacteria by a filter, and deodorizes odors such as body odor and tobacco smell. .

In general, air cleaners are classified according to the air purification method according to the filter. Filters used in air cleaners are classified into mechanical, electric, and ionic types according to their types, and each method has advantages and disadvantages.

For example, mechanical is a method of purifying air by using a dust collecting filter to remove foreign substances (fungus, pet hair, pollen, etc.) from the air passing through it. Such a mechanical method effectively removes foreign substances from the air, but the filter has to be replaced periodically, and there is a disadvantage that it cannot remove odors, viruses, bacteria, and the like.

By passing air through the + and-plates spaced at predetermined intervals, the electrical forms + poles on foreign matter particles in the air passing through the + pole plates, and + foreign matter particles with poles are electrically adsorbed on the pole plates. The air is purified. This electric type has the advantage that it can be implemented in a relatively small size, but when the foreign matter is attached to the + and-plates, the purification ability drops sharply. Likewise, there is a disadvantage that can not remove odors, viruses, bacteria, etc.

The ion type is a method of purifying air by injecting ions into the air to allow the ions to be adsorbed to the foreign matter particles, and then passing these air through the positive electrode dust collector plate to adsorb the foreign matter particles to which the ions are attached. This ion type has the advantage of very low noise by not using a separate fan, but the dust collector must be cleaned frequently, it can remove odors, viruses, bacteria and the like.

In addition, it is possible to remove odors in the air using activated carbon, but a large amount of activated carbon is required for effective odor removal, and this method also has a disadvantage in that viruses or bacteria cannot be removed.

In recent years, various methods can be used in combination, or by taking advantage of each method, air purifying ability can be improved. Furthermore, research and development of air purifiers, which can remove bacteria or viruses, and inexpensive maintenance costs, are actively conducted. have.

Inhaled). Air three-dimensionally sucked in three directions is introduced into the orifice 800 through the rear through-hole 320 of the lower end of the rear frame 300.

The air introduced into the orifice 800 is guided to the front of the orifice 800 again through the front guide 450 under the orifice 800, and the air of the filter assembly 730 together with the air sucked from the other side. Guided forward.

Therefore, the air of the indoor space for air purification is sucked into the air cleaner through the front / rear, left / right, and bottom of the air cleaner by the rotational force of the fan 820. That is, three-dimensional suction of indoor air occurs over the entire direction except for the upper surface where the discharge port 340 of the air cleaner is located.

The air sucked into the air cleaner in three dimensions as described above is sterilized by ozone generated from the ozone generator 240. That is, the ozone is injected into the outside air sucked from the outside to sterilize the air sucked in and the filter assembly 730. It is introduced into the suction through parts 140 and 320 and passes through the filter assembly 730.

At this time, since the filter assembly 730 is composed of a plurality of filter assemblies and has various functions, the filter assembly 730 removes foreign substances such as dust in the air, as well as odors.

That is, in the prefilter 730a, dust of relatively large size contained in the inhaled air is primarily filtered out, and fine dust passing through the prefilter 730a is filtered by the HEPA filter 730b. More than 99.97% of fine dust of 0.3 micrometer (micrometer) is almost eliminated.

The odor particles contained in the air passing through the hepa filter 730b are first removed by the deodorization filter 730c, and then carbon nanoparticles having stronger odor removal power than the deodorization filter 730c. It is removed again by the ball (CNB) filter 730d.

In the ozone removal filter 730e, ozone generated in the ozone generator 240 is removed, and in the nanosilver filter 730f, bacteria propagation in the filter is suppressed.

The air from which foreign substances and odors are removed while passing through the filter assembly 730 is introduced into the fan 820 installed at the center of the orifice 800 and then discharged in the centrifugal direction by the rotational force of the fan 820. The air discharged by the fan 820 is discharged back to the indoor space through the discharge port 340 formed on the upper surface of the air cleaner.

Then, after using such an air cleaner for a long time, the filter should be replaced. In this case, the side panel 500 is removed, and then the filter door 760 provided inside the side panel 500 is removed to remove the filter of the filter case 720 inside the filter guide 740. Pull it out to slide and replace the required filter.

If the new filter assembly 730 is to be mounted, the reverse order of separation described above is used.

The scope of the present invention is not limited to the above-exemplified embodiments, and many modifications are possible based on the present invention to those skilled in the art within the above technical scope.

In the air purifier according to the present invention as described in detail above, the rear panel is coupled to the rear frame by a predetermined distance, and the spaced apart gap is a rear suction port. The air in the rear of the air cleaner is sucked through the rear suction port.

Therefore, the air cleaner can suck and purify the air from the front, the bottom and both sides, as well as the rear, so that the effect of improving the air purification ability can be expected.

In addition, the rear panel is spaced apart and coupled to the rear frame to further enhance the appearance of the air cleaner without being affected by the internal structure, and the rear panel does not directly expose the suction hole to the outside so that external foreign substances It is possible to protect the interior of the air cleaner from.

In addition, the rear panel is formed of a simple coupling structure by the fixing protrusion and the fixing groove, so even when the internal management such as replacing the fragrance canning can be easily separated by separating the rear panel by hand to perform and combine operations It becomes convenient.

In addition, the intake of air occurs in three dimensions in a favorable direction to induce a smooth circulation of indoor air. In addition, the effect of inhaling a larger amount of air is added to maximize the air purification efficiency of the air cleaner can be expected to effect to clean the indoor air in a short time.
