Description

Air sterilizer with pipe narrowing structure {AIR STERILIZER WITH PIPE NARROWNESS STRUCTURE}

The present invention relates to an air sterilizer with a duct constriction structure.

Modern people are exposed to various pollutants and viruses, and cases of not only contact infection but also non-contact infection through the air are rapidly increasing. In particular, face-to-face situations are essential in various service industries where customers and employees conduct business face-to-face, such as public institutions such as civil complaints, financial institutions such as banks, and medical institutions such as hospitals. In this way, there are cases of infection caused by inhaling air containing various droplets and airborne viruses while an unspecified number of people are working face-to-face.

To improve this problem, air sterilizers are installed as needed. In conventional air sterilizers, the fluid passage area of the path through which air moves is kept constant, allowing air to flow in and out within a short period of time. Therefore, there is a problem that the time for air to be sterilized inside the sterilizer is significantly shortened, thereby reducing sterilization efficiency.

Figure 1 is a perspective view of an air sterilizer 100 according to an embodiment of the present invention, Figure 2 is an exploded perspective view of an air sterilizer 100 according to an embodiment of the present invention, and Figure 3 is an embodiment of the present invention. This is a cross-sectional view of the air sterilizer 100 according to .

1 to 3, a first part 110 that discharges air to the outside, a second part 120 that sterilizes the air discharged through the first part 110, and a second part 120 that sterilizes the air discharged through the first part 110. It may include a third part 130 that introduces external air into the interior of 120. Here, the first part 110 may be formed so that the passage area of the air provided from the second part 120 gradually decreases. This structure reduces the area through which air passes through the process of air being delivered through the second part 120 being discharged to the outside through the first part 110, thereby increasing the discharge speed and reducing the fluid passing area. A pressure change occurs in the space within the second part 120 before the fluid passage area is reduced, and the fluid stays in the space inside the body 121 for a predetermined period of time. The air may be sterilized during the time it remains within the body 121. Additionally, the surface constituting the inner area of the first part 110 may be formed as a curved surface to prevent the generation of vortices etc. during the process of discharging air.

Meanwhile, the second part 120 is located in the tubular body 121, a plurality of brackets 123 extending radially from the distal part of the body 121, and the distal part, and has an area where the brackets 123 extend. It may include a sterilizing unit 125 that irradiates light to the excluded sterilizing area 123a. That is, as shown in FIG. 2, the bracket 123 may be formed to extend from the center of the tubular body 121 to reach the inner peripheral surface of the body 121.

In order to promote coupling between the second part 120 and the first part 110, the second part 120 may include an assembly guide portion 121a. The assembly guide portion 121a may be preferably located at the top of the bracket 123 so as not to block the air flow. It is formed to be inclined inward so that the first part 110 can be guided to correspond to the second part 120 when inserted.

In addition, it may further include a blade 124 that is interposed through a pin connection so as to be rotatable with the bracket 123 and is positioned in a direction parallel to the direction in which air moves. The blade 124 may guide air to move between the sterilization areas 123a formed inside the body 121. For example, air introduced from the outside can be discharged back to the outside through the first part 110 via the second part 120. As described above, due to the pressure change, the air inside the second part 120 The air stays for a certain amount of time. Therefore, turbulence may occur within the second part 120 as air is provided by the blower fan 135 during the stay, and the air generating the turbulence is moved clockwise or counterclockwise to the adjacent sterilization area 123a. ) so that it can be moved to . This utilizes the flow of air moving through turbulence, and the blades 124 do not generate forced convection.

As described above, the blade 124 can be rotated around the pin by being connected to the pin, and the above-described effect can be expected while maintaining the rotated state at a predetermined angle. Furthermore, the light irradiation angle of the sterilizing unit 125 may include at least the sterilizing area 123a formed from the distal part. Air moving to the adjacent sterilizing area 123a through the blade 124 may be sterilized by the sterilizing unit 125. The sterilization may be performed by light irradiated by the sterilizing unit 125, and the light irradiated by the sterilizing unit 125 may be irradiated laterally at an angle of 120 degrees according to this example.

Accordingly, the 120-degree area divided by the bracket 123 extending in three directions can become the sterilization area 123a, and the blade 124 can facilitate air movement between each sterilization area 123a. For example, if the air is not guided by the blade 124, a dead point may occur where air stagnates. To prevent this, the air flow can be circulated using turbulence to prevent the dead point from occurring.

In addition, the third part 130 includes a coupling part 132 on which the second part 120 is seated and coupled, a plurality of support parts 131 that support the coupling part 132 upward and extend vertically from the ground, and a coupling It may include a blowing fan 135 that is coupled to the part 132 and transports air into the second part 120 through the space formed between the plurality of support parts 131. The air introduced by the blowing fan 135 is external air, and since the inflow direction of the blowing fan 135 is from downward to upward, the air can be separated from the ground so that the air can be guided. To this end, the support portion 131 provided on the outer peripheral surface of the blower fan 135 extends upward from the ground, thereby supporting the blower fan 135 upward. Of course, the blowing fan 135 can be supported indirectly by the support part 131 being seated and coupled to the coupling part 132 supporting upward. Optionally, for more stable placement, a base 131a is provided at the ground side end of the support part 131 and can be coupled to the ends of the plurality of support parts 131.

In order for air to flow in like this, a suction space (137a) may be provided between the support portions 131, that is, below the blowing fan 135. The second part is provided in the suction space (137a) through the blowing fan 135. A filter 137 through which air passes before flowing into 120 may be disposed. The filter 137 can perform primary filtering by physically filtering foreign substances floating in the incoming air.

Here, the primary filter 137 ring refers to physical filtration through the filter 137, and the air passing through the filter 137 is sterilized in the sterilization area 123a within the body 121 and is used as a secondary filter. (137) It can be a ring. Here, the sterilization performed in the sterilization area 123a is by light irradiated from the sterilization unit 125, as described above, and the sterilizer includes a reflector located along the inner surface of the body 121 to further enhance the sterilization effect. 122) may further be included. With this arrangement, the reflector 122 can reflect the light irradiated from the sterilizing unit 125 to have a more active influence on the air in the sterilizing area 123a.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims described later but also by equivalents to the claims.
