Description

Flow path structure of air sterilization and purification device

The present invention relates to a flow path structure applied to an air sterilizing and purifying device that introduces outside air to perform sterilization and purification and then discharges the air.

An air purifier is understood as a device that sucks in polluted air, purifies it, and then discharges the purified air. For example, the air purifier may include a blower for introducing external air into the interior of the air purifier and a filter capable of filtering dust or bacteria in the air.

In general, an air purifier has an inlet and an outlet for introducing and discharging air. In addition, a blower for circulating air, a filter for filtering contaminants contained in the introduced air, and the like may be provided inside the air purifier.

Looking at the operating principle of the air purifier including the above-described configuration, the air purifier sucks outside air into the suction port through an air flow generated while the blower is driven, and pollutants contained in the sucked air are stored inside the air purifier. The air filtered through the filters of various materials provided and the pollutants are filtered out is discharged to the outside through the outlet.

An air sterilizer is understood as a device for sterilizing bacteria contained in the outdoor air by sucking in the outdoor air, and then discharging it.

In general, an air sterilizer can be distinguished from an air purifier that filters out contaminants contained in the outdoor air through a filter in that it sterilizes bacteria contained in the outdoor air. The air purifier generally sterilizes the air sucked in from the outside through ozone, ions, ultraviolet rays, photocatalysts, and the like.

Recently, in order to supply clean air, an air purifier capable of performing the functions of an air purifier such as purifying air through a filter method using various filters or a plasma method using ions has been proposed.

However, in order to increase the sterilization effect of the air, since the sterilization of the air must be continued for an effective time, the flow of the air must be made slowly. Conversely, in order to effectively filter foreign substances contained in the air, the filtering effect increases as the air flow increases, and the filtering effect decreases as the air flow decreases.

Therefore, in the case of an air purifier that has been proposed recently, it is possible to remove some of the pollutants or harmful substances contained in the air and sterilize the bacteria contained in the air to a certain extent, but there is a limit to completely sterilizing the bacteria contained in the air. There is a situation.

In addition, the UV sterilizer refers to a device that sterilizes the bacteria on the object to be disinfected by irradiating ultraviolet rays to the object to be disinfected. Most of them were for sterilization, and as the sterilization effect of ultraviolet rays became more widely known, recently, among ultraviolet sterilizers, devices that sterilize indoor air using ultraviolet rays have appeared.

Ultraviolet sterilizer for indoor air sterilization is prepared for the purpose of preventing infection of the human body by bacteria in the air, and is used in various places such as operating rooms and clean rooms as well as general homes. It is intended to include an ultraviolet lamp to be used, a ballast connected to the ultraviolet lamp, and a blower connected to the chamber so that external indoor air is introduced into the chamber and discharged to the outside of the chamber while passing through the interior.

The blower, the ultraviolet lamp and the ballast are accommodated in the chamber, and the blower and the ballast are generally respectively fixed to different positions inside the chamber by separate brackets.

In the ultraviolet sterilizer configured as described above, when the blower is driven, indoor air is sucked into the chamber through the inlet of the chamber, sterilized while passing around the ultraviolet lamp, and then discharged to the outside of the chamber through the outlet of the chamber.

However, since the conventional ultraviolet sterilization apparatus as described above moves along the longitudinal direction of the chamber in which the ultraviolet lamp is installed, the air residence time in the chamber is very short, so there is a problem that sufficient sterilization effect cannot be expected. In particular, although sterilization treatment can be expected to some extent for the air moving close to the UV lamp, a sufficient amount of UV irradiation is not made for the air moving close to the inner wall of the chamber and away from the UV lamp. This phenomenon cannot be completely sterilized, and thus the overall sterilization efficiency is lowered.

Accordingly, the present invention aims to solve the above-described problem.

One of the various tasks of the present invention is to provide a flow path structure that is applied to an integrated air sterilization and purification device that sucks in outside air, performs purification and sterilization, and then discharges it.

One of the various problems of the present invention is to provide a flow path structure capable of increasing the residence time of the outside air introduced through the suction port in the air sterilization and purification device.

In general, an air purifier and an air sterilizer are provided respectively, and even in a device in which a household air purifier and a sterilizer are combined, the air purifier removes dust in several circulation processes, and air sterilization is effective in sterilizing air for a period of time should be done For this reason, when the air forms a fast airflow to secure the air cleaning ability, the sterilization ability is greatly reduced.

For the above reasons, in order to sterilize the air in the air purifier, even if the air purifying ability is reduced, the air must flow slowly or a method having a very strong sterilization power must be used.

However, according to the above-described structure of this embodiment, the light source unit 23 is located in the center of the inner space of the second body 20, and the guide unit 21 is radiated along the outer periphery of the light source unit 23 to the light source unit ( 23), as it is provided in a spiral shape along the longitudinal direction, it is possible to increase the time the air stays inside the second body 20, and thus it is possible to prevent deterioration of the sterilization ability while maintaining the output of the fan motor.

It moves radially and moves spirally along the longitudinal direction of the light source unit 23 .

In this case, one surface of the first guide member 211 and one surface of the first filter 212 are spaced apart from each other to face each other, so that one surface of the first guide member 211 and the first filter 212 are spaced apart from each other.

In the above-described structure, the first application layer 2123 and the second guide member 213 are spaced apart from each other and provided at positions facing each other, so that between the first application layer 2123 and the second guide member 213 . The diffusion of chemicals is easy in the flow path formed in the However, a diffusion rate may be reduced in a flow path formed between one surface of the first filter member 2121 and one surface of the first guide member 211 .

Accordingly, the first filter member 2121 of the present embodiment may be formed in a porous mesh structure. As the first filter member 2121 is formed of a porous mesh structure, the chemical substances generated in the first application layer 2123 applied to the other surface of the first filter member 2121 are transferred to the first filter member 2121 ) can be easily diffused into a flow path formed between one surface of the first guide member 211 and the first guide member 211 .

In the structure of the present invention described above, according to the structure of the guide part, it is possible to increase the residence time of air in the air sterilization and purification apparatus, thereby increasing the sterilization efficiency of air, and photocatalysts in all flow paths formed by the guide part The diffusion of by-products generated by the chemical reaction of the light source and the light source can increase the sterilization power of the air.
