Description

[0001] Air purification equipment [0002]

The present invention relates to an air sterilization and purification apparatus for removing contaminants such as suspended particulates, bacteria, and toxic gases contained in air in a room to maintain the cleanliness of an indoor space, and more particularly, And the sterilized air is removed by the ultraviolet rays and the photocatalyst, and then the sterilized air containing the anion and the ozone is discharged into the room by the air sterilization purifier .

Generally, an air sterilization apparatus is a device that filters out dust or germs in the air to clean the air, and is mainly used in a work environment of a factory, including a large amount of dust in an office, a home, or the air. At this time, the air sterilizing apparatus has an air inlet and an air outlet, and has a blowing device for sucking indoor air into the main body and forcedly blowing air into the main body, and dust contained in air introduced into the main body of the air- And a filter device for filtering bacteria.

The filter device for purifying the air typically comprises a prefilter composed of a mesh having a plurality of grids for filtering relatively large dust particles and an electrostatic dust collecting electrostatic filter for collecting dust using the ionization phenomenon of the dust particles And a fine dust filter made of a fine nonwoven fabric and collecting fine dust.

Thereafter, the indoor air passes through the interior of the air sterilization apparatus body by the operation of the air blowing apparatus, and the air through which the filter apparatus passes is purified. At this time, when the filter device is used for a long period of time, dust and germs adhere to the outer surface, the pressure of the filter device increases, and the suction force of the suction portion is rapidly lowered due to contaminated air, can not do it.

Accordingly, in recent years, the filter device is capable of filtering dust and germs in the air by separating, replacing, cleaning, and rejoining the filter device installed inside the air sterilization purifier from time to time. However, the above-described air sterilization apparatus has a problem that the user has to check the condition of the filter device from time to time to separate and clean it, and the replacement cost increases when the user changes the filter apparatus.

In addition, the indoor air introduced into a part of the side of the air sterilization apparatus has a problem that it can not pass through the entire area of the filter apparatus. That is, even though the overall area of the filter device can be maximized to the efficiency of the filter device by passing the contaminated air uniformly, the area of the suction section of the conventional air device corresponds to a portion of the overall area of the filter device, The indoor air that has not passed through the entire area of the filter device has reduced the air purification efficiency of the filter device. As a result, the replacement period of the filter device is inevitably shortened, and the maintenance cost is increased due to the frequent replacement period of the filter device, thereby causing an economical burden to the user.

Therefore, the polluted indoor air passing through the filter device uniformly passes through the entire area of the filter device, thereby improving the purification efficiency of the contaminated air in the filter device, and sterilizing the sterilizing device And to develop an air sterilization purification apparatus which is constructed so that purified air can be discharged including anion and ozone.
