The present invention relates to a sterilization module device included in an air purifier or a device having a sterilization function.

Light in the vicinity of visible light is divided into infrared rays (wavelength 780 nm or more), visible rays (wavelength 780-400 nm), and ultraviolet rays (wavelength 100-400 nm) depending on the wavelength. It is separated into -B (wavelength 280~315nm), UV-C (wavelength 200~280nm), and vacuum UV (wavelength 100~200nm). The lower the wavelength, the higher the energy of the light, and the higher the energy can be supplied for the same time.

As a special effect for each wavelength of ultraviolet rays, in the case of UV-A, industrial use using a photochemical band is advantageous, so it is used for curing and printing of UV ink, and in the case of UV-B, it is used for treating skin diseases. On the other hand, in the case of high energy UV-C, when certain conditions are met enough to use the term sterilization line, it destroys the DNA and RNA structure of the cell, making the cell unable to live, and has the effect of leading to death. is becoming

In particular, UV LEDs are being developed by improving the UV lamp, which is a fluorescent lamp, which has low light efficiency, since the wavelength of 254 to 275 nm is mainly used as the wavelength for sterilization, and devices that emit light have been developed.

Prepare the light source horizontally or squarely on the corresponding surface to maintain more than enough time for the bacteria to be killed by squeezing so that all bacteria collected in the filter can be sterilized, and repeat this situation using a fan continuously. To provide a structure of a device that circulates air in a space in which the corresponding air purifier or sterilizer is placed and collects germs so that repeated sterilization can be effectively performed.

Therefore, it goes without saying that the first component mentioned below may be the second component within the spirit of the present invention.

Like reference numerals refer to like elements throughout.

Each feature of the various embodiments of the present invention may be partially or wholly combined or combined with each other, and as those skilled in the art will fully understand, technically various interlocking and driving are possible, and each embodiment may be implemented independently of each other, It may be possible to implement together in a related relationship.

On the other hand, the potential effects that can be expected by the technical features of the present invention that are not specifically mentioned in the specification of the present invention are treated as described in the present specification, and this embodiment is provided to those of ordinary skill in the art. It is provided to more completely explain the present invention, and the details shown in the drawings may be exaggerated compared to the actual implementation of the present invention, and the detailed description of the configuration determined to unnecessarily obscure the gist of the present invention is omitted or abbreviated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

There are various methods to sterilize bacteria, but as a method using UV light, a method of culturing the target bacteria and irradiating UV light with an effective wavelength for more than a predetermined time from a certain distance is used. It is enough energy to kill most bacteria in a minute or so. On the other hand, in order to sterilize moving bacteria, instantaneous energy is very high, or light must be applied while following moving bacteria, which is a very difficult problem. In order to solve this problem, it is advantageous to constantly fix the bacteria.

General air purifiers control the flow of air forcibly, suck air in a certain space, and filter dust, bacteria, and harmful gases contained in the air. It refers to a device that discharges air again to gradually clean the air in the space where the air purifier is placed over time. Most of these air purifiers include a HEPA filter or a porous ceramic filter, which is a fine dust filter, to filter out only fine dust, or include a module that uses infrared heating to remove bacteria or uses a specific wavelength of UV light. Or, to decompose or adsorb harmful gases such as ammonia, toluene, formaldehyde and acetaldehyde, an adsorption filter such as activated carbon is used, or a module for decomposing gas using its own catalysis such as a photocatalyst is included.

Since the original purpose of such an air purifier is focused on fine dust, it creates an air flow and forcibly moves the air in a certain direction. Bacteria pass through in a short time even if you put on a sterilizer, so even with a device with good sterilization efficiency, the time the bacteria are exposed to ultraviolet light, which contains the energy to sterilize, shortens, and the sterilization efficiency drops dramatically. This device is designed to increase the effectiveness of sterilization by repeatedly circulating and sterilizing air in a limited space, so it is a very low-efficiency method to actually sterilize bacteria.

In addition, except for a device that seals and sterilizes a small space similar to this, a device (sterilizer) dedicated to circulating air uses the same method, so the effect of sterilization is not very high.

In the case of UV rays of a specific wavelength, it is essential to expose the UV rays to the bacteria for a certain period of time due to the inherent characteristics of the device that kills the cells of the bacteria due to exposure to the bacteria to be sterilized for a certain period of time. A pass-through sterilization device is a device that goes against its characteristics because it cannot give enough time and energy to kill bacteria.

Accordingly, the necessity of a device configured to further increase the effect is emphasized.

The principle of sterilization of ultraviolet rays is that when ultraviolet rays are irradiated to DNA, the molecular structure of thymine among the bases of DNA is intensively destroyed. Thymine that absorbs UV light sticks to neighboring thymine or cytosine. When thymine is polymerized in this way, DNA replication cannot take place properly, so its function as a living organism stops. The difference in sensitivity to ultraviolet light between bacteria is because the amount of thymine contained in DNA is different. In addition, ultraviolet light oxidizes phospholipids and proteins that make up cell membranes, preventing the extension of life activities of bacteria.

The sterilization effect of ultraviolet rays varies depending on the wavelength, intensity, and irradiation time. In particular, UV with a wavelength of 250 to 260 nm is the most effective. There is a relationship.

In addition, the UV sterilization effect has a similar effect on many bacterial species and viruses. In particular, the sterilization effect on new strains is similar to that of known viruses, which is a huge advantage over sterilization by drugs.

The survival rate of bacteria exposed to the irradiated UV light decreases almost exponentially with respect to the amount of irradiation (radiation intensity × irradiation time), and is expressed as follows.

S = P/P0 = e(-Et)/Q

S: survival rate of sterilization

P: Number of bacteria after irradiation (number of colonies)

P0: number of bacteria before irradiation (number of colonies)

E : Radiation intensity of sterilization line (μW/cm^2)

t : irradiation time (min)

Q: Basic dose - sterilization radiation dose (μWmin) required for survival rate S to become 1/e (36.8%)

The value of Q for E. coli in relatively dry room temperature air is about 5 μW min/cm^2, but it is about twice this in humid air, and 3 to 5 times on the medium, In water, it is about 8 times the value. This data means that most bacteria do not die well even after UV sterilization depending on the humidity, and it indicates that the bacteria survive well if there is moisture.

It is a drawing. 3 to 6 are views showing sterilization authentication data of E. coli in a stationary state by the air purifier type sterilization module device using the filter collection of FIG. 1 .

Referring to Figure 1, an object of the present invention is to use a fan in the configuration of the sterilization module of the air purifier or sterilizer to send the flow of air in one direction, and in one of the directions of the air, in the passage through which all the air passes. By installing filters such as HEPA filters and ceramic separator filters, the filter collects fine dust as well as bacteria so that they cannot pass through and stays filtered. Prepare the UV light source horizontally or squarely on the corresponding surface so that the light source can reach it, and maintain it for more than enough time for the bacteria to be killed by squeezing, so that all the bacteria collected in the filter can be sterilized, and keep this situation continuously To provide a structure of a device that repeatedly circulates air in a space in which the corresponding air purifier or sterilizer is placed using a fan to collect bacteria so that repeated sterilization can be effectively performed.

For an effective sterilization effect on an air purifier or sterilizer, it is necessary to collect it in a certain space and sterilize it. Includes airflow passages to prevent leaks elsewhere.

A fan is a device for introducing air from one direction of an air purifier or sterilizer and discharging air in the other direction. place it At this time, it can also serve as a fan for air flow to filter out fine dust from the air purifier.

In addition, the filter is installed in the vertical direction to the air flow of the passage so that all of the air moved using the preceding fan can pass through the passage prepared previously. Depending on the shape of the installed filter, the front or rear end of the fan can be installed on The filter is a separator-type filter with a passage hole smaller than the size of the bacteria to be filtered and collected. Use a HEPA filter (H10 ~ H14) or a ceramic filter with an open pore diameter of 0.05 ~ 10 μm, or a filter with such a passage hole. It may be a filter of a different material.

In addition, the light source is arranged to be placed horizontally or obliquely to the filter so that the filter where the collected bacteria are collected can be applied to a wide area as possible, so that the energy of the light source is close enough to reach the filter. The wavelength of the light source is one that emits some of the wavelengths from 200 to 300 nm, and the light output of 10,000 to 20,000 Ws/cm^2 for bacteria or viruses and about 80,000Ws/cm^2 for mold is used. use. The light source configured in this way can be fixed using a PCB (circuit printed board) or an individual process device, and all or part of the part except for the light source emitting point is removed so that the air flow is not blocked in the fixed light source and the light source fixing device or the PCB. Punch a hole to allow air to flow smoothly.

It is placed on a certain passage so that the previously placed fans, filters, and light sources can be placed sequentially, and the air flows in one direction through the passage. It is constructed so that there are no side gaps.

In addition, some components can be shared with an air cleaning device or module equipped with a filter system for removing fine dust, a titanium dioxide photocatalyst device or module for decomposing harmful gases, and an activated carbon module for adsorption and removal of harmful gases, or sequentially in the same space. It can be arranged as a function to further improve the efficiency by combining with other functions.
