The present invention is to sterilize air in an elevator used by many people to prevent infection from bacteria or viruses and to provide a clean space. The means for sterilizing and purifying air directly is separated inside the exhaust duct or outside the elevator ceiling. The present invention relates to an air sterilization and purification system for an installed elevator.

In general, airborne microorganisms refer to the total number of microorganisms present in a room surrounding a human being. On average, more than 80% of the time people spend indoors in 24 hours a day. However, while most people are deeply aware of the seriousness of air pollution, they do not realize that indoor air pollution has a greater effect on humans than outdoor air pollution.

Since the 1970s, indoor air pollution has been treated as a new environmental pollution problem in developed countries such as the United Kingdom and the United States, but Korea still lacks awareness and studies are inadequate.

Various airborne microorganisms are known to cause headaches, dry cough, asthma and allergies, and some of the dust is composed of living biological substances that contain viruses or bacteria, and these particles can cause allergies to severe death. You may. If contaminated indoor air is continuously circulated through artificial facilities in a confined space and its concentration is increased, it can cause direct damage to the human body, such as a respiratory disease. In addition, when in the same space as a person contaminated with microorganisms, microbes are released into the air through breathing, coughing, sneezing, talking, and other activities, and the microorganisms released into the air are suspended in the air or breathed by others depending on their size and density. Inhalation into the trachea.

Table 1 below defines the commonly known bacteria contained in the air, their characteristics and the onset of the disease.

TABLE 1

Table 2 below shows guidelines and recommendations for the specification of microbial counts in indoor air in countries around the world, including Korea.

TABLE 2

Table 3 below shows the standards for maintaining indoor air quality in Korea (Article 3).

TABLE 3

In addition, bacteria contained in aerosols, such as air conditioners and humidifiers, can cause lung cancer in the elderly or infants who are weakly resistant, even though they are usually not pathogenic at all. It is a problem.

The average household air temperature of bacteria was 602.5 CFU / m ^3, as reported in the Korea Health Industry Development Institute's report on assessment of the impact of indoor environmental pollution on residents' health and development of prevention models (Hong Cheon Soo, 2002). The case was found to be 2.4 to 5.2 times higher than the mean value, 4 to 8.9 times higher than the average value of 352.5 CFU / m ³ of outdoor air. In the case of children's home were more severe by The Play 4,764 CFU / m3, the cooking chamber is higher than approximately 7.9 times from 4.2 times of the average value to 2,548 CFU / m ^3, based on the outside is higher at about 7.2 times to 13.5 times.

These results can not be concluded in that there is a big deviation (260 ~ 16,140 CFU / m ³ ) in each facility, but apart from the difference between school facilities and day care centers, the school classrooms, cooking rooms, and playrooms of day care centers average than the recommended standard (500 CFU / m ³⁾ 5.1 times that (school cooking 2,548 CFU / m ³⁾ is the to be hygienic environment in excess of 9.5 times (nursery school 4,764 CFU / m ³⁾ over-exposure to the bacteria in Able to know.

Recently, various techniques have been implemented to sterilize and purify airborne microorganisms, but each has disadvantages and needs supplementation or new measures. The main technologies so far are shown in Table 4 below.
