Description

Plasma sterilizing module of air sterilization device

The present invention relates to a plasma sterilization module of an air sterilization device, and more particularly, it is applied by being inserted into the air sterilization device, and it oxidizes and removes bacteria such as viruses and bacteria floating in the air of the room by corona discharge, It relates to a plasma sterilization module of an air sterilizer for safely protecting the human body from infectious disease factors by promoting the decomposition of volatile organic compounds.

Recently, it has become a social problem due to the spread of the COVID-19 virus, and as non-face-to-face activities and financial working hours increase, the time spent working in the indoor space of an apartment or house, which is a residential space, is increasing. The health of family and improvement of indoor air quality in the workplace, which is a face-to-face work space, are essential.

As a sterilization method applied to the conventional sterilizer, there are a UV lamp use technology, a plasma use technology, a filter collection use technology, etc., and the most used method is a technology that collects by a filter. However, the UV lamp technology improves the sterilization power when both air contact and UV irradiation by titanium catalyst coating are made at the same time.

In the plasma use technology, it is necessary to increase the amount of plasma ions generated in proportion to the indoor use area to ensure the effect of eradicating mold bacteria in the back space and viruses in the indoor air. There are cases where it is misleading.

There is a limit to the lifespan of the collection technology by the filter. At the end of its lifespan, it causes a problem of further polluting the indoor air. In general, it is cumbersome to replace once a year, and the contaminated filter produced during replacement has a problem of causing 2.5 million secondary environmental wastes per year as industrial waste.

Therefore, research on measures to solve the problems of increasing the sterilization efficiency of the sterilization function, extending the life of the sterilizer, and generating secondary environmental pollution that occurred in the prior art is being actively conducted.
