Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sterilizing air cleaning apparatus,

The present invention relates to a sterilizing air purifying apparatus and a control method thereof, and more particularly, to a sterilizing air purifying apparatus and a sterilizing air purifying apparatus which are capable of providing an optimum sterilization effect and an air purifying effect A sterilizing air purifying device, and a control method.

Generally, a sterilization system is designed to administer a sterilizing medium to a surface or object to remove surface or object living organisms.

Application areas of sterilization systems include, but are not limited to, sterilization, disinfection of objects, and decontamination of space / area.

A sterilization system is used, for example, to sterilize surgical instruments, food, or pharmaceutical packaging.

Examples of the contamination purification system in the area / space include those used for disinfecting various surfaces and objects inside the room, for agricultural use, for example, breeding or breeding of animals.

It is known that pathogenic microorganisms are infecting the environment and infecting them, and disinfection of the area / space is becoming more and more important.

This is particularly important because antibiotic resistance strains are found in the environment and are becoming increasingly difficult to treat.

A challenge in existing space / area contamination clean-up systems is to obtain a sterilizing medium that is efficiently applied to all surfaces to be disinfected.

In particular, many conventional space / area contamination purification systems have limitations in the number of disinfection sources included in the system due to limitations in cost and size.

In addition, the directivity of the sterilizing medium in existing space / area contamination purification systems is largely fixed, and consequently, conventional systems often emit large amounts of sterilizing medium to simultaneously disinfect a large number of surfaces in space or areas .

The problem with the application of the bulk sterilizing medium is that the room or a portion of the periphery can be overexposed to the sterilizing medium, which in turn wastes the sterilizing medium and potentially wastes the time and / or energy required for disinfection treatment.

Also in some cases, when the germicidal medium is sprayed throughout the space, a sufficient amount of the germicidal medium does not reach a portion of the space / area, particularly a surface relatively far from the sterilizing source or a surface not in line with the sterilizing source.

Insufficient exposure of the germicidal medium leaves an undesirable number of pathogenic microorganisms on the surface or object, and the likelihood of infection by a person coming into contact with the surface is greatly increased.

Another problem with conventional space / area contamination purification systems is that the consideration and priorities of objects and surfaces in the space performing the disinfection process have not been considered and, as a result, the disinfection process for the space / When finished, there is a possibility that the object or surface in the space where the contamination amount is likely to be large is not sufficiently disinfected.

In particular, the source of sterilization of the space / area contamination purification system is often located or installed near a central point in space such that the sterilization medium exposure from the source of sterilization to the space / area periphery is substantially uniform throughout the space / area.

Likewise, when a plurality of disinfectors are included in the system, it is an effort to disinfect the entire space at a given disinfection process, and is uniformly distributed over the entire space other than near the specific object.

The disinfection source of the space / area contamination purification system can also be located near an object or surface such as an acupressure bed in a sickroom, but it may be desirable to place a sterilizing source near a particular object, There is a problem in that it can not adequately deal with the necessity of disinfection of other objects or surfaces in a space / area such as a handle or a light switch of the apparatus.
