The present invention relates to an air purifier for corona virus sterilization that can remove not only ultrafine dust, yellow sand, but also bacteria and corona virus, and more specifically, it sucks indoor air and uses the negative (-) electrode and positive (-) electrode of the discharge dust collecting module ( +) A high voltage is applied to the electrode to cause a corona discharge to ionize the air around the electrode so that harmful substances in the air (e.g., ultrafine dust, yellow sand, as well as bacteria and corona virus) take on a negative charge, The harmful substances of the negative charge are electrodeposited toward the positive (+) electrode to remove them, and at the same time, the harmful substances are irradiated with strong high-power ultraviolet (UVC) for a long time to maximize the sterilization and virus inactivation effects, thereby improving the indoor air quality. It relates to an air purifier for corona virus sterilization that can maintain a comfortable and sanitary environment.

In general, an air purifier provides a more comfortable indoor environment for users by removing not only dust in the air, but also gaseous pollutants and bacteria that cause odor.

When air purifiers are classified according to dust collection and deodorization methods, mechanical air purifiers that use filter media or classify water to perform dust collection or dust collection and deodorization at the same time, and high voltage to collect dust or perform dust collection and deodorization functions at the same time It can be divided into an electric air purifier and a combined air purifier that combines a mechanical air purifier and an electric air purifier.

In addition to these air purifiers, they are divided into filter method, electrostatic filter method, electrostatic precipitation method, and composite method according to the method of collecting pollutants. method and photocatalytic method.

The conventional air purifier using high-pressure discharge receives polluted air from the outside and has a high-pressure pipe and a high-pressure line installed on an air passage partitioned in a certain shape, so that foreign substances in the air are electrodeposited. It is a technology in which foreign substances are separated from the air by the corona discharge, and the separated foreign substances are electrostatically collected on a charged plate to purify the air.

On the other hand, indoor air may be polluted by moisture or mold, and various pathogens floating in the hospital exist in the hospital room, and thus not only the patient but also the general public in the patient waiting room are exposed to the contamination of the pathogen.

In public facilities such as hospitals and restaurants, viruses, Escherichia coli, O-157, salmonella, etc. that cause various food poisoning in the summer may exist, and if food is served in such a virus-contaminated state, it may cause group food poisoning. Since it has only a simple function of purifying foreign substances in the air, there is a problem in that it cannot fundamentally block contamination sources such as mold or bacteria that occur indoors, and pathogens or viruses that occur in hospitals.

In general, an air purifier has a function of filtering/deodorizing various pollutants and odors after sucking polluted air into the room through a fan installed therein. and various filters, such as pre-filters and HEPA filters, which are mounted to collect or adsorb and remove contaminants and odors contained in the air sucked in by the fan, and formed to discharge the purified air through the filter to the outside It consists of an exhaust port, etc.

However, since the conventional air purifier simply filters air, it is insufficient to sterilize bacteria and supply perfectly purified air.

Disclosed is a photocatalytic sterilization module for air purification comprising a.

However, in conventional air purifiers, even when trying to sterilize bacteria and viruses, the speed at which bacteria and viruses float is proportional to the flow of air. There is a problem in that the blowing performance of clean air is weakened due to limitations in the amount and speed of air when the amount of UV irradiation is increased recklessly.

In addition, the conventional air purifier has a problem in that the effect of removing ultrafine dust, bacteria and corona virus is inferior.

In addition, it is possible to maximize the sterilization and virus inactivation effect by irradiating the harmful substances with the negative (-) charge toward the positive (+) electrode and simultaneously irradiating the harmful substances with strong high-power ultraviolet (UVC) for a long time.

Second, in the prior art, even when trying to kill bacteria and viruses, since the floating speed of bacteria and viruses is proportional to the flow of air, the time to irradiate the bacteria and viruses with ultraviolet rays is too short, so the effect of killing bacteria and viruses is reduced. However, in the present invention, the dust collecting plate is configured in an arc shape, and the air is guided to move along the inner circumferential surface of the dust collecting plate, maintaining the blowing capacity of clean air and irradiating the air with ultraviolet rays for a long time to obtain sterilization and virus inactivation effects. can be further maximized.

Third, since a powerful high-power UV emitting module is installed inside the housing, UVC light does not leak out of the housing at all, so there is an advantage that it is safe for the human body.

Fourth, the housing is composed of a double partition wall between the inner wall and the outer wall, and a space is formed between the inner wall and the outer wall to discharge the heat radiated from the heat sink to the outside of the housing through the discharge hole by the operation of the blower module. It is possible to effectively prevent overheating of the UV emitting module.

Fifth, the conventional air purifier has a disadvantage in that the dust collection rate rapidly drops when the particle size of the dust is less than 10 μm.

In the present specification and drawings, preferred embodiments of the present invention have been disclosed, and although specific terms are used, these are only used in a general sense to easily describe the technical content of the present invention and help the understanding of the present invention. It is not intended to limit the scope. It will be apparent to those of ordinary skill in the art to which the present invention pertains that other modifications based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein.

It is to be understood that the present invention is capable of various modifications and may take many forms, and is not limited to the particular form set forth in the above detailed description, but rather the spirit and scope of the present invention as defined by the appended claims. It is to be understood to include all modifications and equivalents and substitutes within.

For example, in this embodiment, while sterilizing bacteria with ultraviolet rays in a wavelength band of 254 nm, which has strong bacterial sterilization power, and at the same time sterilizing COVID-19 in the indoor air with far ultraviolet rays in a wavelength band of 222 nm, at an indoor temperature of 20 to 35 ° C. It is also desirable to control the ultrasonic humidification to maintain a humidity of 55 to 65% so that the inactivated environment of COVID-19 can be maintained.
