JP2013188447A - Sterilizer in which air filter having sterilizing power is combined with ozone generator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such a problem that sterilization in conventional food factories or the like uses organic acids, however, resistant bacteria or the like emerge due to the long-term use, and also, the dust and bacteria in the atmosphere are deposited on an air filter by circulating air in a room, therefore, the deposited bacteria grow and it leads to secondary contamination.SOLUTION: An air filter having sterilizing power is incorporated into a sterilizer. The dust and bacteria in the atmosphere are deposited on the air filter. The deposited bacteria are sterilized by the sterilizing power of the air filter. Clean air permeated through the air filter is mixed with ozone and sprayed by rotating a discharge port by 360 degrees so as to sterilize airborne bacteria and adhesive bacteria.

Description

  The present invention relates to a sterilizer capable of not only sterilization / deodorization but also dust removal.

People, the inner and the outside air plant one million / 1m ³ or more of the bacteria have been floating-attached. If these bacteria are harmful to the human body, people will become ill. In food factories, food spoilage and bacteria-attached products will serve as a hotbed and carrier for bacteria, and humans will have a negative impact on food. Will affect.

  In factories that require disinfection and sterilization of many foods, organic acids such as sodium hypochlorite, ethyl alcohol, and acetic acid are used for sterilization.

  Also, for dust and mold that are floating in the atmosphere, circulate the atmosphere using an air filter and attach the dust and mold that are floating in the air filter to cause dust and mold in the atmosphere. Is removed.

  For this reason, sodium hypochlorite, ethyl alcohol, acetic acid, etc. have been used as conventional sterilization techniques. However, these chemical sterilizations can produce resistant bacteria when used for many years, and can use ethyl alcohol as a nutrient source. In factories where fungi (yeasts and molds) appear or where organic acids such as acetic acid are used, the growth of acid-resistant molds has become a problem, causing problems in drug sterilization.

  The sterilization mechanism is completely different from the above chemical sterilization, and it has sterilization, deodorization and decolorization power, easily decomposes with unstable gas, and ozone which cannot be resistant because it does not remain has been widely used for sterilization. . In addition, ozone can have a bactericidal effect when used in combination with other chemicals.

  However, according to the above technology, the air filter was used to circulate the room air to remove dust, but it is represented by microorganisms such as dust and bacteria floating in the air attached to this air filter. Particulate matter cannot be killed, and the collected microorganisms may have proliferated and caused secondary infection.

  Therefore, the present invention allows air in the atmosphere to pass through an air filter with a single sterilizer, and attaches dust, bacteria, etc. floating in the air to the air filter to make dust-free and aseptic clean air. , Take in air in the atmosphere, separate oxygen and nitrogen in the atmosphere, mix only oxygen with ozone gas and dust-free and aseptic clean air to make dust-free and sterile clean ozone gas with sterilizing power By spraying around 360 ° around the sterilizer, airborne bacteria and adherent bacteria can be sterilized, and the bacteria attached to the air filter sterilize the bacteria with the sterilizing power of the air filter. It is an object to provide a sterilizer that does not cause secondary contamination.

  In order to solve the above problems, the first invention is a sterilizer characterized by combining a sterilizing air filter and an ozone generator.

  The sterilizing apparatus according to claim 1, wherein the second invention is characterized in that a discharge port of ozone air in which dust-sterilized air is mixed with ozone gas having sterilizing power rotates 360 ° and sprays.

  According to the first invention or the second invention, dust and bacteria are attached to the air filter from air in the atmosphere to clean air, and the bacteria attached to the air filter are sterilized by the sterilizing power of the air filter, Eliminate secondary infection, on the other hand, generate high-concentration ozone with an ozone generator, mix high-concentration ozone with clean air to make clean ozone gas, and sterilize by spraying around 360 ° around the sterilizer .

Embodiment of the Invention

  The air blower (2) built in the sterilizer passes through the air filter (1) to take in the outside air, and dust and bacteria floating in the air adhere to the air filter, making it dust-free and sterile clean air. Clean air is sprayed from clean ozone gas outlet (6). This clean ozone gas outlet can be rotated 360 ° and sprayed uniformly around the sterilizer.

  In addition, dust and bacteria floating in the air attached to the air filter sterilize the bacteria and microorganisms collected by the air filter's sterilizing power, so they do not grow and cause secondary infection.

  On the other hand, the nitrogen separator (3) built in the ozone generator (5) separates nitrogen, which is said to be about 70% in the atmosphere, from the air in the atmosphere and releases it into the atmosphere. In (4), high-concentration ozone is generated using only oxygen which is said to be about 20% in the atmosphere.

  The generated high-concentration ozone is mixed with dust-free and sterile clean air that has passed through the air filter and sprayed into the atmosphere as clean, sterile and dust-free clean ozone gas through the clean ozone gas outlet (6). Disinfect the surroundings.

  In addition, this device can detect the differential pressure before and after the air filter and judge the replacement time of the air filter based on the pressure difference. Features such as an automatic operation function that can set the operation time and forced manual operation, and a function that can be selected according to the volume of the room, and the operation status can be changed depending on the dust and germs situation of the installation location Have

Effect of the invention

  According to the sterilizing apparatus characterized by combining the sterilizing air filter of the present invention and the ozone generator, the sterilizing apparatus is installed at the place where the ambient air is sucked by the blower (2). Filter (1) is allowed to pass through, and air filter (1) is used to attach dust and bacteria. The attached dust and bacteria are sterilized and grown with an air filter, and there is no concern about secondary contamination. It can sterilize the floating bacteria and adhering bacteria on the floor and walls. Therefore, it is possible to prevent dust collection, sterilization, deodorization, and mold with this single sterilizer, and there is no concern about secondary contamination from the air filter, which is the dust collection part.
