Description

Air purifier using sterilization module

The present invention relates to an air purifier using a sterilization module, and more particularly, foreign substances are filtered while external polluted air passes through a filtration filter, and the filtered air is sterilized and sterilized by corona discharge while passing through the sterilization module. , It relates to an air purifier using a sterilization module, in which the clean air that has passed through the sterilization module is discharged to the outside through an air outlet to maintain comfort at all times.

In general, air purifiers can be divided into a filter method, an electric dust collection method, and a water method according to the air purification method.

The most common method here, the filter method, is a method of purifying indoor air by filtering dust or impurities using a filter. , a HEPA filter that suppresses the growth of fine dust and general bacteria and mold as a tertiary filter, and a carbon filter that removes odors and odors as a tertiary filter. There were problems in that it was difficult to manage parts, the cleaning work had to be done separately, and in the case of activated carbon filters, it was impossible to regenerate, and all filters were periodically replaced, adding to the economic burden of consumers.

In addition, the conventional electrostatic precipitation method has the ability to purify the air using an electrostatic filter, but it cannot adsorb and remove odors or bacteria contained in the air. functions only to remove .

On the other hand, to deodorize the odor in the conventional air purifier, a filter made of powdered activated carbon and granules gave a deodorizing effect in the air. It is an artificial filter made as a result of clogged pores, which causes harmful microorganisms contained in the air to multiply and become a secondary source of infection. There was a problem that could not be seen.
