Description

Space sterilizer with air cleaning function

The present invention relates to a space sterilizer having an air cleaning function, and more particularly, to a space sterilizer having an air cleaning function, in which dust generation is eliminated through filtering from the beginning of introduction of outside air, It is a natural, effective and efficient space without the need to generate vortex to increase the residence time by prolonging the treatment time by thoroughly treating the untreated material through the oxidation reaction which is the mutual light of the ultraviolet lamp and the photocatalyst. To a space sterilizer having an air cleaning function improved to enable sterilization.

In recent years, as population growth and industrialization have progressed rapidly, air pollution has become more intense and has had a negative impact on people, animals and animals.

These air pollutants include airborne bacteria such as super bacteria, H1N2 (swine flu / bird flu), infectious germs, Salmonella, Escherichia coli, Staphylococcus aureus, Listeria, Legionella, Norovirus and fungi, Such as Nox (nitrogen oxides), SOx (sulfur oxides), volatile organic compounds (VOCs), formaldehyde (sick house syndrome), ammonia, toluene, acetaldehyde (main cause of tobacco smell) .

Especially, the recent Merges and Oxy events, which have been raised by social problems, have a huge impact.

If the contaminated air is inhaled without being sterilized, the human body may be adversely affected.

As a result, recently, it has become increasingly popular for hotels, motels, and other places where families and the public gather, shopping centers (such as department stores and marts), cultural facilities (museums, exhibition halls, concert halls, (Schools, kindergartens, academies, etc.), offices, shopping malls, etc., air purifiers are installed to purify the contaminated air so that people can take in purified clean air to live in a more pleasant environment.

Conventional air cleaners are devices that purify air by using a filter system using various filters or a plasma system using ions. It removes some pollutants and harmful substances contained in the air and can sterilize a part of the bacteria contained in the air However, there is a limit in completely sterilizing the bacteria contained in the air, and the inside is completely sealed, which makes it difficult to replace, repair, and clean the component parts, resulting in inconvenience in aftercare.

In order to solve this problem, a space sterilizer for sterilizing and deodorizing air by a photocatalytic oxidation reaction by combining a photocatalyst material and a broadband ultraviolet ray has been developed in order to improve the sterilization and deodorization effect of air. Examples thereof are Korean Patent No. 10-0660138 Korean Registered Patent No. 10-2008-0103037 (Publication Date: December 26, 2008), Korean Patent No. 10-0943328 (Registered Date: Feb. 11, 2010) 10-1055358 (registered date: Aug. 23, 2011), and the like.

Conventional prior art space sterilizers including the above-mentioned prior art documents sterilize and deodorize air using a photocatalytic oxidation reaction. The air sterilizer is used to sterilize and deodorize air using a photocatalyst activated by ultraviolet rays and ultraviolet rays, And the deodorized air and ions are discharged into the air to purify the indoor air. In comparison with the conventional filter type or plasma type air cleaner, the sterilizing and deodorizing effect is greatly improved.

However, since the sterilizer unit (unit) for sterilizing, deodorizing and discharging the introduced air is integrally formed with the main body, the conventional air purifier according to the related art is difficult to replace, repair and clean, In addition, since the air circulation path is simple, the time taken for the air introduced into the sterilizing apparatus to react with the ultraviolet ray and the photocatalyst is short, which has a limitation in maximizing the sterilizing and deodorizing effect of the air.

An example of this improvement is disclosed in Korean Patent No. 10-1676817 (Oct. No. 10-1676817 discloses a radial space sterilizer for sterilizing and deodorizing air by causing a photocatalytic oxidation reaction of a photocatalyst material and a broadband ultraviolet ray to generate a sterilization and deodorization effect by providing a plurality of guide plates to increase the residence time of the treated air. Is increased.

However, in the above-mentioned Japanese Patent No. 10-1676817, it is true that the treatment efficiency is increased by increasing the residence time of the treatment air. However, in order to increase the residence time, Since the vortex is generated as a result of the radial arrangement of the gaps, the structure is structured to sterilize and deodorize only through the oxidation reaction of the photocatalyst as well as the backflow phenomenon and dust generation of the processing air, and is processed only in the short space between the photocatalytic cell array and the plurality of guide plates Even if the residence time was increased, there was a limit in actually improving the treatment efficiency.
