Description

Thermal infrared sterilizer {Thermal infrared sterilizer}

The present invention relates to a thermal infrared sterilizer, and more particularly, is harmless to the human body and prevents secondary contamination by liquid disinfectants by sterilizing germs using infrared rays and heat of 75° C. or higher without using liquid disinfectants. It relates to a thermal infrared sterilizer that can be used.

The livestock industry is an industry that breeds livestock and poultry, produces materials necessary for people using them, and uses the products. As the mass consumption era coincides with the development of livestock industry and technology, farmers are breeding livestock in large quantities.

This has the advantage of mass supply, but has the fatal disadvantage of being annihilated in the event of an animal epidemic. That is, avian influenza (AI), foot-and-mouth disease, swine cholera, highly pathogenic infectious diseases, etc. are recently threatening animal epidemics, and if it is found to have occurred, livestock of nearby livestock farms can only be culled.

For example, Foot-and-mouth disease (FMD) is a virulent infectious disease that ranks first among OLE ListA Diseases of livestock designated by the International Bureau of Animal Health. It appears in animals with split hooves (such as sheep, deer, and elephants), and is characterized by a rapid rise in body temperature, blisters (blisters) on the mouth, tongue, hooves, nipples, etc., and loss of appetite, resulting in severe illness or death.

In addition, pig cholera (swine fever) is a type 1 infectious disease that only pigs naturally contract. It is a systemic, acute infectious disease that is very contagious. Once infected, 100% of people die regardless of age. It is characterized by shaped ulcers and hemorrhagic sepsis.

Since foot-and-mouth disease or swine cholera is a disease caused by a virus, there is no special treatment.

In the prior art, a device for preventing infection by a moving vehicle or person by installing a quarantine fence on a road to prevent infection and continuously spraying a pesticide is widely used.

However, since the conventional disinfection devices as described above continuously spray chemical solution, the amount of chemical solution consumed is large, and when disinfecting a moving vehicle, the chemical solution is sprayed only on the outside of the vehicle, such as both sides and the bottom surface of the vehicle, so that the inside of the vehicle There was a problem in that secondary contamination such as soil contamination and water contamination occurred without pest control for passengers and drivers.

In particular, the conventional disinfection device is capable of disinfecting the exterior of the vehicle, but there is a problem in that the disinfectant cannot be sprayed into the interior of the vehicle to be disinfected.

That is, when a driver visits an already contaminated farmhouse, many germs are smeared on his feet and he moves inside the vehicle to drive, but it is impossible to disinfect. In addition, disinfection work on people as well as vehicles should be performed, but it is practically impossible to spray liquid disinfectant directly on people, so there is a problem that quarantine measures cannot be properly performed.

After all, in the past, disinfectants are used to disinfect. tap water. There were problems in causing environmental destruction due to chemicals, requiring a large number of manpower to be mobilized, and preventing quarantine equipment from freezing in winter and failing to function.

On the other hand, the infrared lamp 220 of the lamp module 200 installed inside the chamber 100 as described above maintains its exothermic temperature to be 30° C. during normal times (a state in which no one enters or exits the stay space of the chamber) and stays there. By setting the temperature at 70 to 80° C. when a visitor is located in the space 120, the time for heating the stay space 120 to a certain temperature can be reduced, so that the visitor can be sterilized quickly.

That is, sterilization by infrared rays is due to a thermal action, and since it takes time for the infrared lamp 220 to reach 70 to 80° C. at a temperature lower than 30° C., power consumption increases.

However, as described above, the temperature rise period is shortened by maintaining the heating temperature of the infrared lamp 220 at 30 ° C in normal times and 70 to 80 ° C when the visitor is located in the staying space 120. Accordingly, the time during which a visitor is located in the stay space 120 can be reduced, and malfunction or damage to the infrared lamp 220 caused by a sudden temperature rise of the infrared lamp 220 can be prevented.

According to the thermal infrared sterilizer according to the present invention as described above, it is possible to sterilize germs on clothes and skin by heat action without using harmful rays such as ultraviolet rays, and it is possible to sterilize the human body by not spraying liquid disinfectant directly to the person entering the room. It is harmless to water and can prevent secondary contamination and freezing by liquid disinfectants.

On the other hand, the present invention is not limited to the above-described embodiments, but can be implemented with modifications and variations within a range that does not depart from the gist of the present invention, and such modifications and variations are also considered to belong to the technical spirit of the present invention. .
